A rare presentation of a paediatric sinonasal inverted papilloma

Abstract

Sinonasal inverted papilloma (IP) is a benign tumour with an extremely low incidence in children. We report the case of an 11-year-old Caucasian male presenting with recurrent right-sided epistaxis, nasal obstruction and a mass in the right nasal cavity. An initial diagnosis of a nasopharyngeal angiofibroma was considered; however, on detailed histological examination, the mass was found to be an inverted papilloma. This report aims to increase awareness of IP in the paediatric age group, as well as reinforcing the role of endoscopic surgery in the management of this condition.

Brunner’s gland hyperplasia: an unusual duodenal submucosal lesion seen in four patients

Abstract

Brunner's gland hyperplasia is an extremely rare benign hamartomatous lesion seen in proximal duodenum. Difficulty in diagnosing the condition pre-operatively puts the surgeon in dilemma for deciding appropriate management. We retrieved details from prospectively maintained retrospective data from January 2014 to April 2018. Four patients were identified of which three were males and one was female. Symptoms ranged from 4 days to 4 years, with abdominal pain, vomiting and malena being predominant. No patients were identified with diagnosis pre-operatively. Diagnosis was made on histopathological examination of the resected specimen and none of them were having malignant features. At a median follow up of 11 months, no patient had recurrence and were symptom free. Brunner's gland hyperplasia is a rare elusive duodenal pathology, symptomatically mimicking alarming duodenal lesions and mostly diagnosed on histopathology of specimen. Patients may harbour the lesion for long periods with little symptoms and upon treatment have good outcomes.

Minimally invasive drainage of a giant ovarian mucinous cystadenoma associated with a mature cystic teratoma

Abstract

A 26-year-old, otherwise healthy female presented to the Emergency Room for the evaluation of abdominal pain. It was immediately apparent that she had a massively distended abdomen. History revealed progressive abdominal distension over several years. Evaluation for pregnancy was negative and a computed tomography (CT) scan demonstrated a 38 × 32 × 23 cm septated cystic mass. Careful controlled partial needle decompression of the cyst, removing 18.5 l of fluid, was followed by a mini-laparotomy with complete removal of a multi-loculated cystic ovarian mass approximately 45 lb in weight. Pathology was consistent with mucinous cystadenoma of the ovary in association with a mature cystic teratoma. This surgical technique of percutaneous drainage of the cyst, followed by mini-laparotomy is a valuable example of a safe and effective minimally invasive treatment modality for giant ovarian mucinous cystadenomas.

Corneal Toxicity Induced by ABT-414 Therapy for Glioblastoma Multiforme: A Case Report

Background: To describe a case of corneal toxicity associated with the use of the epidermal growth factor receptor (EGFR) inhibitor ABT-414 in the treatment of glioblastoma multiforme. Case Presentation: Case report of a 56-year-old male with glioblastoma multiforme who developed mild painless blurred vision after systemic treatment with the investigational EGFR inhibitor ABT-414. The patient had best corrected visual acuity of 20/60 right eye and 20/50 left eye. Ophthalmic examination revealed corneal toxicity with whorl-like opacities in the inferior interpalpebral cornea. The patient was treated with topical fluoromethalone and lifitegrast, and his ocular symptoms as well as the corneal findings improved. Conclusions: The systemic use of EGFR inhibitor ABT-414 may be associated with corneal toxicity and the effects are reversible with treatment.

A Comparison of Spinal Anesthesia Versus Monitored Anesthesia Care With Local Anesthesia in Minimally Invasive Fetal Surgery

BACKGROUND: Minimally invasive fetal surgery is commonly performed to treat twin-to-twin transfusion syndrome with selective fetoscopic laser photocoagulation and twin-reversed arterial perfusion sequence using radiofrequency ablation. Although an increasing number of centers worldwide are performing these procedures, anesthetic management varies. Both neuraxial anesthesia and monitored anesthesia care with local anesthesia are used at different institutions. We sought to determine the efficacy and outcomes of these 2 anesthetic techniques for fetal procedures at our institution. METHODS: All patients undergoing minimally invasive fetal surgery for twin-to-twin transfusion syndrome or twin-reversed arterial perfusion sequence over a 6-year time period (2011–2016) were reviewed. Patients receiving monitored anesthesia care with local anesthesia were compared with those receiving spinal anesthesia in both selective fetoscopic laser photocoagulation and radiofrequency ablation fetal procedures. The primary outcome examined between the monitored anesthesia care and spinal anesthesia groups was the difference in conversion to general anesthesia using a noninferiority design with a noninferiority margin of 5%. Secondary outcome measures included use of vasopressors, procedure times, intraoperative fluids administered, maternal complications, and unexpected fetal demise within 24 hours of surgery. RESULTS: The difference in failure rate between monitored anesthesia care and spinal was −0.5% (95% CI, −4.8% to 3.7%). Patients receiving monitored anesthesia care plus local anesthesia were significantly less likely to need vasopressors, had a shorter presurgical operating room time, and received less fluid (P

Speaker Gender Representation at the American Society of Anesthesiology Annual Meeting: 2011–2016

The American Society of Anesthesiologists (ASA) Annual Meeting is the primary venue for anesthesiologists to present research, share innovations, and build networks. Herein, we describe gender representation for physician speakers at the Annual Meeting relative to the specialty overall. Details of ASA Annual Meeting presentations for individuals and panels were abstracted from the ASA archives for 2011–2016. Observed speaker gender composition was compared to expected composition based on the gender distribution of members of the ASA. There were 5167 speaker slots across 2025 presentations and panels. Of the speaker slots, 3874 were assigned to men and 1293 to women. Speaker slot gender composition was relatively consistent between 2011 and 2016 (annual percentage 22.3%–27.7% women, trend test P = .062). ASA membership composition of women increased slightly over the study period (24%–28%). The overall observed number of women in speaker slots over the study period did not differ significantly from what would be expected based on the ASA membership composition (25.0% observed vs 25.9% expected; P = .153). However, the percentage of single speakers who were women was significantly less than would be expected based on the ASA gender distribution (20.2% observed vs 25.9% expected; P

The Impact of Postoperative Intensive Care Unit Admission on Postoperative Hospital Length of Stay and Costs: A Prespecified Propensity-Matched Cohort Study

BACKGROUND: In this prespecified cohort study, we investigated the influence of postoperative admission to the intensive care unit versus surgical ward on health care utilization among patients undergoing intermediate-risk surgery. METHODS: Of adult surgical patients who underwent general anesthesia without an absolute indication for postoperative intensive care unit admission, 3530 patients admitted postoperatively to an intensive care unit were matched to 3530 patients admitted postoperatively to a surgical ward using a propensity score based on 23 important preoperative and intraoperative predictor variables. Postoperative hospital length of stay and hospital costs were defined as primary and secondary end points, respectively. RESULTS: Among patients with low propensity for postoperative intensive care unit admission, initial triage to an intensive care unit was associated with increased postoperative length of stay (incidence rate ratio, 1.69 [95% CI, 1.59–1.79]; P

General Anesthesia Alters the Diversity and Composition of the Intestinal Microbiota in Mice

Dysbiosis of the intestinal microbiota has been shown to result in altered immune responses and increased susceptibility to infection; as such, the state of the intestinal microbiome may have profound implications in the perioperative setting. In this first-in-class study, we used 16s ribosomal RNA sequencing and analysis in a mouse model of general anesthesia to investigate the effects of volatile anesthetics on the diversity and composition of the intestinal microbiome. After 4-hour exposure to isoflurane, we observed a decrease in bacterial diversity. Taxonomic alterations included depletion of several commensal bacteria including Clostridiales. These data identify volatile anesthetics as potential contributors to microbial dysbiosis in the postoperative patient. Accepted for publication October 17, 2018.

Remote Surveillance Technologies: Realizing the Aim of Right Patient, Right Data, Right Time

The convergence of multiple recent developments in health care information technology and monitoring devices has made possible the creation of remote patient surveillance systems that increase the timeliness and quality of patient care. More convenient, less invasive monitoring devices, including patches, wearables, and biosensors, now allow for continuous physiological data to be gleaned from patients in a variety of care settings across the perioperative experience. These data can be bound into a single data repository, creating so-called data lakes. The high volume and diversity of data in these repositories must be processed into standard formats that can be queried in real time. These data can then be used by sophisticated prediction algorithms currently under development, enabling the early recognition of patterns of clinical deterioration otherwise undetectable to humans. Improved predictions can reduce alarm fatigue. In addition, data are now automatically queriable on a real-time basis such that they can be fed back to clinicians in a time frame that allows for meaningful intervention. These advancements are key components of successful remote surveillance systems. Anesthesiologists have the opportunity to be at the forefront of remote surveillance in the care they provide in the operating room, postanesthesia care unit, and intensive care unit, while also expanding their scope to include high-risk preoperative and postoperative patients on the general care wards. These systems hold the promise of enabling anesthesiologists to detect and intervene upon changes in the clinical status of the patient before adverse events have occurred. Importantly, however, significant barriers still exist to the effective deployment of these technologies and their study in impacting patient outcomes. Studies demonstrating the impact of remote surveillance on patient outcomes are limited. Critical to the impact of the technology are strategies of implementation, including who should receive and respond to alerts and how they should respond. Moreover, the lack of cost-effectiveness data and the uncertainty of whether clinical activities surrounding these technologies will be financially reimbursed remain significant challenges to future scale and sustainability. This narrative review will discuss the evolving technical components of remote surveillance systems, the clinical use cases relevant to the anesthesiologist's practice, the existing evidence for their impact on patients, the barriers that exist to their effective implementation and study, and important considerations regarding sustainability and cost-effectiveness.

Posterior Reversible Encephalopathy Syndrome due to Hypomagnesemia: A Case Report and Literature Review

Background. Hypomagnesemia can cause various unspecific neurological complications, which can lead to diagnostic confusion. One of these complications is the posterior reversible encephalopathy syndrome (PRES), which is extremely uncommon and has been reported only twice in the English-language literature. Case presentation. We report the case of a 60-year-old man who presented with PRES involving only the cerebellar hemispheres and associated with hypomagnesemia. After excluding all the other possible etiologies of PRES, we started magnesium replacement therapy, which led to a remarkable but fluctuating clinical and chemical improvement. A full recovery with no need for further supplementation was achieved only after discontinuation of a proton pump inhibitor. Conclusions. This case highlights the role of magnesium in the pathophysiology of PRES; thereby, underlying hypomagnesemia should be considered in every PRES case with unclear etiology.

Subglottic acute lymphoblastic leukaemia

Acute lymphoblastic leukaemia (ALL) is one of the the most common malignancies of childhood and can occasionally present as acute airway obstruction. We present the unusual case of a 1-year-old boy who was referred to our Paediatric Otolaryngology (ENT) clinic with a recurrent history of croup. This is the first reported case of localised ALL presenting as a subglottic mass in a paediatric patient. It highlights the need to have a broader differential diagnosis in children presenting with 'recurrent croup' including extramedullary presentation of leukaemia and to have a low threshold for performing endoscopy in such cases.

Metformin-associated lactic acidosis precipitated by liraglutide use: adverse effects of aggressive antihyperglycaemic therapy

Older patients with type 2 diabetes are prone to developing adverse events with aggressive antihyperglycaemic therapy. Metformin-associated lactic acidosis (MALA) is one such rare, life-threatening adverse drug effect. We report the case of a 70-year-old man with a glycated haemoglobin of 7.9% who was on a stable, maximally tolerated dose of metformin for managing his type 2 diabetes. He was initiated on liraglutide injections with hopes to achieve better glycaemic control, but developed unrelenting nausea and vomiting during the third week of treatment. He presented to the hospital with these symptoms and was noted to have severe MALA. He sustained an in-hospital cardiac arrest requiring emergent resuscitation along with vasopressor and mechanical ventilator support. He underwent continuous venovenous haemodiafiltration to remove metformin and correct the acidosis, following which he stabilised and supportive therapy was weaned off. He was discharged from the hospital on insulin therapy with incomplete renal recovery.

Corynebacterium striatum prosthetic valve endocarditis with severe aortic regurgitation successfully treated with transcatheter aortic valve replacement

We describe the case of a 69-year-old man with a history of bioprosthetic aortic valve replacement who presented with Corynebacterium striatum prosthetic valve endocarditis (PVE) complicated by severe aortic insufficiency with refractory cardiogenic shock despite antibiotic therapy. He was considered a prohibitive-risk surgical candidate due to co-morbid conditions and off-label valve-in-valve transcatheter aortic valve replacement (TAVR) was performed after detailed multidisciplinary evaluation. He recovered well without recurrent infection following completion of antibiotics and transthoracic echocardiogram at 12 months showed a normal functioning prosthetic valve. To our knowledge, this is the first reported case of native or PVE treated with TAVR.

Insertion of a Dumon Y-stent via a permanent tracheostoma without using a rigid bronchoscope

A 63-year-old man who had received a permanent tracheostoma after oesophageal cancer surgery developed fistulas in the left and right main bronchi and suffered repeated aspiration pneumonia. Placing an indwelling Dumon Y-stent using a rigid bronchoscope is an option to treat fistula and stenosis at the tracheal bifurcation, but in some cases, it may be difficult to use a rigid bronchoscope in patients with a permanent tracheostoma. In this study, we report placing a Dumon Y-stent in a patient with a permanent tracheostoma using a specially modified stent and forceps instead of a rigid bronchoscope.

Foot drop post varicella zoster virus

Leg pain and weakness can often be seen in a musculoskeletal physiotherapy outpatient setting. While the differential diagnoses for neuropathic pain and weakness is often spine related, this unusual cause for polyradiculopathy is less commonly seen. Shingles is not something routinely seen in a physiotherapy department but is usually associated with skin eruptions and pain but less so with motor loss. The purpose of this case report is to therefore raise awareness that this presentation can occur and should not be mistaken for spinal radiculopathy.

Does ocular inflammation play a role in xeroderma pigmentosum with endothelial dysfunction: an immunological study

We report a case of xeroderma pigmentosum (XP) with endothelial dysfunction where the analysis of tears revealed elevated levels of proinflammatory cytokines, even in the absence of active inflammation and neovascularisation of the ocular surface. Although the role of ultraviolet (UV) radiation-induced inflammation in the occurrence of ocular manifestations of XP is known, little is published on the molecular mechanisms and there are no reports quantifying the presence of inflammatory cytokines in the tears of patients with ocular involvement of XP. Tear analysis demonstrated an increase in inflammatory cytokines and chemokines, especially interleukin-8 (2.38 ng/µg), tumour necrosis factor alpha (0.87 ng/µg) and granulocyte monocyte colony stimulating factor (0.44 ng/µg) as compared with the control eye. Effective management of the underlying UV-induced inflammation and promoting DNA repair may play a vital role in managing ocular manifestations and its sequelae in patients of XP.

Microvascular Capillary Plexus Findings of Commotio Retinae on Optical Coherence Tomography Angiography

Optical coherence tomography (OCT) and histopathology features of commotio retinae (CR) have been established, but alterations of the microvascular macular capillary plexus on OCT angiography (OCTA) has not been previously studied. We present a 46-year-old man who sustained a tennis ball injury to the right eye with visual acuity reduction to 20/30 and grey-white deep macular discoloration, suggestive of CR. Spectral-domain OCT (SD-OCT) showed increased reflectivity and thickness of the ellipsoid zone (junction of photoreceptor inner and outer segments). OCTA revealed no apparent microvascular alterations (right versus left eye) in the foveal avascular zone superficial (0.42 vs. 0.43 mm²) and deep (0.45 vs. 0.44 mm²), superficial foveal capillary density (34.1 vs. 32.6%), and superficial parafoveal capillary density (55.2 vs. 52.2%). Deep macular capillary plexus and choriocapillaris were qualitatively comparable between the two eyes. At 2 months' follow-up, SD-OCT had normalized. CR is characterized by disruption of the ellipsoid zone without detectable alteration of the capillary plexuses.

Novel HAX1 Gene Mutation in a Vietnamese Boy with Severe Congenital Neutropenia

Severe congenital neutropenia (SCN) is a rare disease that involves a heterogeneous group of hereditary diseases. Mutations in the HAX1 gene can cause an autosomal recessive form of SCN-characterized low blood neutrophil count from birth, increased susceptibility to recurrent and life-threatening infections, and preleukemia predisposition. A 7-year-old boy was admitted due to life-threatening infections, mental retardation, and severe neutropenia. He had early-onset bacterial infections, and his serial complete blood count showed persistent severe neutropenia. One older sister and one older brother of the patient died at the age of 6 months and 5 months, respectively, because of severe infection. Bone marrow analysis revealed a maturation arrest at the promyelocyte/myelocyte stage with few mature neutrophils. In direct DNA sequencing analysis, we found a novel homozygous frameshift mutation (c.423_424insG, p.Gly143fs) in the HAX1 gene, confirming the diagnosis of SCN. The patient was successfully treated with granulocyte colony-stimulating factor (G-CSF) and antibiotics. A child with early-onset recurrent infections and neutropenia should be considered to be affected with SCN. Genetic analysis is useful to confirm diagnosis. Timely diagnosis and suitable treatment with G-CSF and antibiotics are important to prevent further complication.

Preoperative continuation of aspirin administration in patients undergoing major abdominal malignancy surgery

Abstract

Purpose

In contrast to that in a nonoperative setting, it has been shown that perioperative administration of aspirin did not decrease the rate of death or myocardial infarction but increased major bleeding risk. Since these conflicting results might be due to concurrent use of anticoagulants and a lower thrombotic risk of patients, this cohort study was carried out for patients at a high thrombotic risk without concurrent use of anticoagulants.

Methods

Medical records for patients who underwent major abdominal malignancy surgery and who were on a preoperative antiplatelet regimen were reviewed. The patients were divided into two groups according to perioperative antiplatelet management: administration of all preoperative antiplatelet agent-suspended (no aspirin) group and only aspirin administration-continued (aspirin) group. The incidence of symptomatic thromboembolic events, frequency of exogenous blood transfusion within 30 days after surgery and the amount of intraoperative bleeding were compared between the two groups.

Results

After propensity score matching, 105 patients of each group were matched. The incidence of perioperative thromboembolic events in the no-aspirin group was significantly higher than that in the aspirin group [7/105 (6.7%) vs 0/105 (0%), 95% CI 1.44–∞, P = 0.016]. In contrast, neither the frequency of exogenous transfusion [21.0% vs 11.4%, 95% CI 0.88–4.38 P = 0.110] nor the amount of intraoperative bleeding [median (interquartile range), ml: 230 (70–500) vs 208 (50–500), P = 0.325] was different between the two groups.

Conclusion

Although the sample size is relatively small, our findings suggest that continuation of aspirin administration is likely to reduce the thrombotic risk but unlikely to increase the bleeding risk of patients who undergo major abdominal surgery for malignancy.

Syphilis as an atypical cause of perianal fissure

Abstract

We present the case of a 29-year-old woman who attended a surgical outpatient clinic with symptoms of perianal fissure due to syphilitic infection. This uncommon aetiology of a common condition is often alluded to in textbooks, but little information exists in the scientific literature regarding the pathogenesis, presentation and treatment of fissure-in-ano secondary to syphilis. We present the case and an overview of the topic aimed at surgeons and clinicians who manage patients with perianal pathology. Syphilis is far from a disease of antiquity; in patients presenting with fissure-in-ano a thorough sexual history and sexually transmissible infection screening in at-risk groups may avoid mis-diagnosis, community transmission and unnecessary procedures.

Toxicological and Biochemical Analyses of an Autopsy Case Involving Oral Overdose of Multiple Antidiabetic and Antihypertensive Drugs

Oral antidiabetics can cause fatal hypoglycemia; although they can be chemically identified and quantified, biochemical investigations are important for assessing the biological consequences of an overdose. Such cases of overdose involving oral antidiabetics may involve other drugs for treating lifestyle-related diseases, particularly antihypertensives. Here, we report a toxicological and biochemical investigation of drugs and biochemical profiles in a fatal overdose involving multiple oral antidiabetics and antihypertensives. A 55-year-old woman died about 2 days after the ingestion of around 110 tablets of antidiabetics and antihypertensives that had been prescribed for her husband. A forensic autopsy and histological analysis demonstrated no evident pathology as the cause of death. A toxicological analysis suggested hypoglycemia and an overdose of antihypertensives as well as the retention of antidiabetics and diuretics in the pericardial fluid. A relatively low pericardial amlodipine concentration was observed, which may have been the result of its long half-life (slower distribution and reduction rate) and/or possible affinity with the myocardium. In addition, a biochemical analysis indicated hypoglycemia, without increased serum insulin and C-peptide, but with increased glucagon levels, as the possible influence of glibenclamide overdose. These observations suggest the usefulness of a combination of toxicological and biochemical analyses in postmortem investigations involving a fatal overdose of such drugs.

Efficiency of the TOF-Cuff™ for the evaluation of rocuronium-induced neuromuscular block and its reversal with sugammadex: a comparative study vs. acceleromyography

Abstract

Purpose

The aim of this study was to compare TOF-Cuff™ (TOF-C) and TOF-Watch™ (TOF-W) data following rocuronium-induced neuromuscular block and its reversal with sugammadex.

Methods

Twenty elderly patients aged 68–82 years scheduled for surgery under general anesthesia were enrolled in this study. After induction of anesthesia, neuromuscular block resulting from administration of 0.6 mg/kg rocuronium was concurrently evaluated using TOF-C and TOF-W. The onset of neuromuscular block and duration until the first twitch response following post-tetanic count (PTC) and 2 Hz train-of-four (TOF) stimulation reappeared were evaluated. When the response to the TOF stimulus was detected with both monitors, additional doses of rocuronium were administered to maintain the neuromuscular block. After surgery, 2 mg/kg sugammadex was administered when 1–2 TOF twitches were observed with the TOF-W and the time required for facilitated recovery to a TOF ratio of > 0.9 was assessed.

Results

Regression analyses revealed no statistically significant differences in the mean [SD] onset of rocuronium-induced neuromuscular block [127.8 (27.2) s, 123.5 (30.5) s], time to recovery of the first PTC twitch [23.9 (8.0) min, 25.4 (8.6) min], time to recovery of the first twitch with TOF stimulation [37.2 (8.8) min, 38.9 (11.1) min] and time to adequate reversal with sugammadex [139.2 (30.6) s, 151.8 (31.5) s] between TOF-C and TOF-W, respectively. Bland–Altman analyses also showed acceptable ranges of the biases and limits of agreement between the two methods.

Conclusions

TOF-C may be clinically applicable for the evaluation of both the depth of neuromuscular block and restoration of neuromuscular function.

Postoperative thoracic and low back pain following endovascular aortic repair associated with stenting location

Abstract

Background

We have noted that patients frequently complain of thoracic or low back pain after undergoing an endovascular aortic repair, which we speculated was caused by the indwelling stent.

Methods

We investigated the patients who underwent an elective thoracic or abdominal endovascular aortic repair (TEVAR or EVAR) and noted the location of stent, and postoperative pain. The incidence of either thoracic or low back pain at individual vertebra levels was determined, after which we fitted the sigmoidal function to the discrete data to obtain a cut-off line. The study patients were then divided into 2 groups using the cut-off line to compare the incidence of pain.

Results

We analyzed 96 patients (68 TEVAR, 28 EVAR). The incidence of thoracic pain was significantly higher in TEVAR as compared to EVAR (26.5% vs. 3.6%, P = 0.01), while that of low back pain was significantly higher in EVAR (35.7% vs. 16.2%, P = 0.04). With the cut-off line for thoracic pain set at the 12th thoracic vertebra, the incidence of thoracic pain was significantly higher in patients with the upper end of the stent above the cut-off as compared to at a lower point (26.5% vs. 3.6%, P = 0.01). As for low back pain, the cut-off line was set at the 9th thoracic vertebra, and the incidence of that pain was significantly higher in patients with the lower end of the stent below that line (30.9% vs. 0.0%, P < 0.01).

Conclusion

Thoracic and low back pain after an endovascular aortic repair procedure were associated with stenting site.

Transmesenteric hernia with two mesenteric defects in an adult

Abstract

Transmesenteric hernia is a rare cause of small bowel strangulation in adults and, to our knowledge, no one has reported the existence of two mesenteric defects in an adult. Our patient was a 73-year-old Japanese woman who presented to our emergency department complaining of abdominal pain and nausea. Computed tomography with contrast enhancement revealed a closed loop obstruction in the pelvis, suggesting small bowel strangulation due to an internal hernia. The emergency exploratory laparotomy indicated a small bowel strangulation caused by a transmesenteric hernia. With the examination across whole parts of the mesentery, we identified another small defect. Both defects were closed by suture intraoperatively, and the patient's postoperative course was satisfactory. Searching for whole parts of the mesentery after the reduction of a hernia can help prevent the recurrence of internal hernias.

Intracystic papillary breast carcinoma in a male patient: a case report and review of literature

Abstract

Intracystic papillary carcinoma of the breast is a rare subtype of breast cancer accounting for approximately 0.5–1% of all breast carcinomas. To the best of our knowledge, the occurrence of this rare subtype of breast cancer in the male is even lower with less than 20 cases reported in the English literature over the past 30 years. We report a case of an elderly Asian male with intracystic papillary breast carcinoma who initially presented with a right sided breast lump for 4 months duration and his subsequent management. In addition, a review of similar cases in the English literature is included.

Off-Label Use of Phakic Intraocular Lens with a “Piggyback” Technique

Purpose: We report a case of a highly myopic pseudophakic patient who received off-label placement of a phakic intraocular lens (pIOL) via a "piggyback" technique, allowing the placement of an intraocular lens (IOL) in his fellow eye, resulting in improved visual acuity and emmetropia. Case Report: A 66-year-old, highly myopic, pseudophakic male with an IOL implant in his left eye was referred for second opinion for surgical options for his phakic right eye. Given the severe myopic status of both eyes, he received off-label placement of a posterior chamber pIOL with a piggyback technique for the pseudophakic left eye followed by standard cataract surgery and intraocular lens implantation in the right eye. For the left eye, uncorrected best visual acuity improved from 20/70 to 20/25. Conclusion: This case demonstrates the successful off-label use of a phakic IOL in a pseudophakic, highly myopic patient with a piggyback technique, resulting in improved visual acuity and ultimately allowing IOL placement in the fellow eye for emmetropia. This off-label use of pIOL can offer ophthalmologists an alternative option for pseudophakic patents with severe refractive error.

Prolapsing mucosal fold: largest reported, presenting with major haemorrhage

Abstract

Prolapsing mucosal folds are uncommon benign colonic lesions that when inflamed may macroscopically resemble, and be confused with, an adenomatous or hyperplastic polyp. They are usually small and rarely cause symptoms. We report the case of a 55-year-old female admitted to hospital following six episodes of significant rectal bleeding. A colonoscopy revealed a 45 × 12 × 5 mm³ pedunculated polyp in the sigmoid colon. There was no evidence of haemorrhoids, colitis or diverticulosis. The polyp was resected by electrosurgical snare at 40 cm and a resolution clip was used to prevent postoperative bleeding. Histology of the polyp demonstrated a polypoid prolapsed mucosal fold with a core of fibrovascular submucosal tissue and normal overlying mucosa. In an extensive review of available literature, no polyp of this size has been reported.

Analysis of Treatment of 3 Patients with Acute-on-Chronic Liver Failure

Acute-on-chronic liver failure (ACLF) is an acute liver decompensation that occurs within 4 weeks on the basis of chronic liver disease. At present, the treatments of ACLF include general supportive treatment, etiological treatment, prevention and treatment of complications, artificial liver treatment, and liver transplantation. Many studies suggest that stem cell therapy may become a new treatment for patients with ACLF. Our department has also tried the application of this treatment. Now, there are three cases of stem cell therapy for patients with ACLF by our department which will be briefly reported.

Prognostic Value of Tissue Oxygen Monitoring and Regional Cerebral Oxygen Saturation Monitoring and Their Correlation in Neurological Patients With Sepsis: A Preliminary, Prospective, Observational Study

Background: There is paucity of literature on the prognostic value of tissue oxygen saturation (StO2) and regional cerebral oxygen saturation (rSO2) in neurological patients with sepsis. In this preliminary study, we investigated the prognostic value of StO2 and rSO2 in a group of neurological patients and correlated StO2 and rSO2 with hemodynamic and metabolic parameters. Materials and Methods: This preliminary, prospective observational study was conducted in 45 adult neurological patients admitted to intensive care unit. Once a diagnosis of sepsis or septic shock was established, parameters of oxygenation (StO2, rSO2, central venous oxygen saturation [ScvO2]), serum lactate, illness severity scores (Acute Physiology and Chronic Health Evaluation score, Sequential Organ Failure Assessment score, Glasgow Coma Scale) were recorded at 0, 6, 12, 24, 36, and 48 hours, and once daily thereafter. Outcomes were in-hospital mortality attributable to sepsis and the Glasgow outcome score at hospital discharge. Results: There was a moderately positive correlation between StO2 and rSO2 at baseline (r=0.599; P=0.001). StO2, illness severity scores and serum lactate, but not rSO2, were significantly different between survivors (n=29) and nonsurvivors (n=16) at baseline and during the first 48 hours. An rSO2 of 62.5% had a sensitivity of 83% and specificity of 67% to differentiate survivors and nonsurvivors of septic shock at 48 hours. StO2 had a higher correlation with ScvO2 and serum lactate than rSO2. Conclusions: StO2 prognosticates survival and favorable/unfavorable outcomes in neurological patients with sepsis. The role of rSO2 in predicting survival in milder form of sepsis is doubtful. The authors have no funding or conflicts of interest to disclose.

Predictive Factors for Hypotension Associated With Supine-to-Prone Positional Change in Patients Undergoing Spine Surgery

Background: Positional change during general anesthesia can cause hypotension. The objective of this retrospective study was to determine predictive factors for hypotension associated with supine-to-prone positional change in spinal surgery patients. Materials and Methods: Data on demographics, current medications, comorbidity, intraoperative mean arterial pressure (MAP), heart rate, pulse pressure variation, tidal volume, peak inspiratory pressure, and propofol and remifentanil effect-site concentrations were collected from 179 patients undergoing elective spine surgery. Hypotension associated with supine-to-prone positional change was defined as >20% reduction in MAP during positional change. Results: Hypotension associated with supine-to-prone positional change was observed in 16 (8.9%) patients.

Dysmorphic Short Stature: Radiological Diagnosis of Trichorhinophalangeal Syndrome

Trichorhinophalangeal syndrome (TRPS), a type of skeletal dysplasia, is characterized by a triad of dysmorphic (bulbous nose and large ears); ectodermal (thin and sparse hair); and skeletal (short stature and cone-shaped epiphyses) findings, and this combination is helpful for early diagnosis and appropriate follow-up. A 14-year-old boy presented with short stature and distinctive facial features, and following the first clinical and biological evaluation, no precise diagnosis was reached. Progressive bilateral development of noninflammatory and painless deformity of his second finger required a radiological exam that highlighted the key elements (cone-shaped epiphyses) for final diagnosis. This case illustrates the difficulties to early recognition of TRPS when the clinical presentation is not complete and radiological findings are missing.

A Rare Cause of Acute Hepatopancreatitis in a Nepalese Teen

Background. Acute pancreatitis (AP) coexisting with acute hepatitis (AH) in children is uncommon. Moreover, a single bacterial cause explaining both the complications is even rarer. Despite familiarity with the usual presentation of enteric fever, atypical presentations can go unnoticed. Case Presentation. A 16-year-old previously healthy male presented to the emergency unit with recurrent swinging pyrexia, abdominal symptoms, and jaundice for a week. Blood work-up revealed deranged liver function tests (LFTs) and elevated pancreatic enzymes. Further assessment with imaging made a diagnosis of AH and AP without necrosis. Blood culture positivity for Salmonella typhi eventually confirmed the diagnosis. Conclusion. This is an uncommon presentation of an infection that is fairly common in our part of globe. Nevertheless, early suspicion and recognition is the key to timely management. Regular follow-ups are required to pick complications up early.

Efficacy of axillary versus infraclavicular brachial plexus block in preventing tourniquet pain: A randomised trial

BACKGROUND Axillary and infraclavicular brachial plexus blocks are commonly used for upper limb surgery. Clinicians require information on the relative benefits of each to make a rational selection for specific patients and procedures. OBJECTIVES The main objective of the study was to compare axillary and infraclavicular brachial plexus block in terms of the incidence and severity of tourniquet pain. DESIGN Single blinded, randomised trial. SETTING University affiliated hospital, level-1 trauma centre. PATIENTS Age more than 18 years, ASAI-III patients undergoing orthopaedic surgery distal to the elbow, with an anticipated tourniquet duration of more than 45 min were recruited. INTERVENTIONS Patients underwent either ultrasound guided axillary brachial plexus block or infraclavicular block (ICB). MAIN OUTCOME MEASURES Incidence of tourniquet pain (onset, severity, associated haemodynamic changes) and block characteristics (block performance/onset times, distribution, incidence of adverse events, patient satisfaction) were recorded. RESULTS Eighty two patients (40 in the axillary block and 42 in the ICB group) were recruited. The incidence (5/36 and 3/35; P = 0.71), onset time mean (SD) were 73.0 (14.8) and 86.6 (5.7) min (P = 0.18) and severity (mild/moderate; 4/1 and 1/2; P = 0.51) of tourniquet pain were similar in the two groups. The incidence of paraesthesia during block performance, and block performance time were greater in the axillary block group (P = 0.0054 and 0.012, respectively). The volume of local anaesthetic administered was greater in the ICB group (P

Gallbladder volvulus—acute cholecystitis ‘with a twist’

Abstract

A Caucasian 92-year-old female was admitted to hospital with acute epigastric pain associated with vomiting. Initial investigations revealed mildly raised inflammatory markers, normal liver function tests but a markedly distended gallbladder with prominent wall thickening. The patient was managed with intravenous antibiotics for acute cholecystitis but deteriorated significantly on Day 2 of admission. An emergency laparoscopic cholecystectomy was performed and we found a gangrenous gallbladder secondary to gallbladder volvulus. The patient recovered well in the postoperative period and was discharged home 7 days later.

Paradoxical embolism through PFO leading to stroke in a gunshot victim with IVC injury

Abstract

A 23-year-old man presented to the emergency department with multiple gunshot wounds to the chest and abdomen, and was taken to the operating room emergently for exploratory laparotomy due to hemodynamic instability. The patient underwent inferior vena cava (IVC), bowel and ureter repair during the procedure, requiring massive amounts of blood products. The patient transferred to the surgical intensive care unit with a routine post-operative course for approximately the next 7 days before presenting with signs of stroke. The patient was diagnosed with deep vein thrombosis in IVC at the repair site on a follow-up venogram. Upon further work-up with echocardiography, the patient was determined to have a patent foramen ovale (PFO), with paradoxical embolism as the most likely cause of the stroke. We present this unusual case of a GSW leading to stroke due to embolism from a venous source through a PFO.

Solitary fibrous tumor of the stomach with high-grade sarcomatous dedifferentiation

Abstract

Solitary fibrous tumors (SFT) are uncommon fibroblastic mesenchymal neoplasms that display a wide range of histologic behaviors. These tumors, which are estimated to account for 2% of all soft tissue neoplasms, typically follow a benign clinical course. However, it is estimated that 10–30% of SFTs are malignant and demonstrate aggressive behavior with local recurrence and metastasis up to several years after surgical resection. We report a case of SFT arising from the stomach, which is an exceptionally rare finding and has been reported only six times in the literature. Our case was complicated by diagnostic dilemma with GIST, highlighting the challenges of diagnosing and characterizing SFTs. Additionally, this tumor was associated with dedifferentiation into undifferentiated pleomorphic sarcoma. To our knowledge, there are no documented cases of a malignant SFT arising from the stomach to demonstrate dedifferentiation into an undifferentiated pleomorphic sarcoma.

Glycocalyx Degradation Is Independent of Vascular Barrier Permeability Increase in Nontraumatic Hemorrhagic Shock in Rats

BACKGROUND: Glycocalyx shedding after traumatic hemorrhagic or septic shock, as well as different resuscitation fluids, has been causally linked to increased vascular barrier permeability (VBP) resulting in tissue edema. In nontraumatic hemorrhagic shock (NTHS), it remains questionable whether glycocalyx degradation in itself results in an alteration of VBP. The composition of fluids can also have a modulatory effect on glycocalyx shedding and VBP. We hypothesized that the shedding of the glycocalyx during NTHS has little effect on VBP and that the composition of fluids can modulate these effects. METHODS: Fully instrumented Wistar-albino rats were subjected to a pressure-controlled NTHS (mean arterial pressure of 30 mm Hg) for 60 minutes. Animals were fluid resuscitated with Ringer's acetate, balanced hydroxyethyl starch (HES) solution, or 0.9% normal saline to a mean arterial pressure of 80 mm Hg and compared with shams or nonresuscitated NTHS. Glycocalyx shed products were determined at baseline and 60 minutes after fluid resuscitation. Skeletal muscle microcirculation was visualized using handheld vital microscopy. VBP changes were assessed using plasma decay of 3 fluorescent dyes (40- and 500-kDa dextran and 70-kDa albumin), Evans blue dye exclusion, intravital fluorescence microscopy, and determination of tissue edema (wet/dry weight ratio). RESULTS: All glycocalyx shedding products were upgraded as a result of NTHS. Syndecan-1 significantly increased in NTHS (mean difference, −1668; 95% confidence interval [CI], −2336 to −1001; P

Progressive Increase in Scholarly Productivity of New American Board of Anesthesiology Diplomates From 2006 to 2016: A Bibliometric Analysis

BACKGROUND: Improving research productivity is a common goal in academic anesthesiology. Initiatives to enhance scholarly productivity in anesthesiology were proposed more than a decade ago as a result of emphasis on clinical work. We hypothesized that American Board of Anesthesiology diplomates certified from 2006 to 2016 would be progressively more likely to have published at least once during this time period. METHODS: A complete list of 17,332 new diplomates was obtained from the American Board of Anesthesiology for the years 2006 to 2016. These names were queried using PubMed, and the number of publications up to and including the diplomate's year of primary certification was recorded. Descriptive statistics and logistic regression analysis were used to analyze the association of the year of primary certification and whether a diplomate had published at least once. RESULTS: The percentage of American Board of Anesthesiology diplomates with ≥1 publication at the time of primary certification increased from 14.9% to 29.3% from 2006 to 2016. The mean number of publications per diplomate more than doubled from 0.31 to 0.79. Logistic regression analysis revealed the year of primary certification as significantly associated with having ≥1 publication (P

Intraluminal Pulmonary Vein Stenosis in Children: A “New” Lesion

Pulmonary vein stenosis (PVS) is a rare disorder that leads to progressive narrowing of the extrapulmonary veins. PVS has been reported in both children and adults and in its worse iteration leads to pulmonary hypertension, right ventricular failure, and death. Multiple etiologies of PVS have been described in children and adults. This review will focus on intraluminal PVS in children. Intraluminal PVS has an estimated incidence ranging from 0.0017% to 0.03%. It is associated with conditions such as prematurity, bronchopulmonary dysplasia, necrotizing enterocolitis, Smith-Lemli-Opitz syndrome, and Down syndrome. Cardiac catheterization and pulmonary vein angiography are the gold standard for diagnosis and anatomic delineation. Other imaging modalities including magnetic resonance imaging, chest tomography, and transesophageal echocardiography are increasingly being used. Mortality of PVS in children is approximately 50%. Predictors of mortality include involvement of ≥3 pulmonary veins, bilateral pulmonary vein involvement, onset of PVS in infancy, elevated pulmonary artery pressure or systolic pulmonary artery-to-aortic pressure ratio, right ventricular dysfunction, restenosis after surgery, distal/upstream disease, and disease progression to previously uninvolved pulmonary veins. Treatment includes catheter-based pulmonary vein dilations with or without stenting, surgical interventions, medical therapy, and in some instances, lung transplantation. Cardiac catheterization for PVS involves a comprehensive hemodynamic and anatomic assessment of the pulmonary veins as well as therapeutic transcatheter interventions. Several surgical strategies have been used. Sutureless repair is currently most commonly used, but patch venoplasty, endarterectomy, ostial resection, and reimplantation are used in select circumstances as well. Medical therapies such as imatinib mesylate and bevacizumab are increasingly being used in an effort to suppress the myofibroblastic proliferation seen in PVS patients. Lung transplantation has been used as an alternative treatment strategy for end-stage, refractory PVS. Nonetheless, despite the different innovative approaches used, morbidity and mortality remain high. At present, the preferred treatment strategy is frequent reassessment of disease progression to guide use of catheter-based and surgical interventions in conjunction with medical therapy.

A Rare Case of Monophasic Synovial Sarcoma of Thoracic Vertebra

Synovial sarcoma of spine is an extremely rare malignancy with poor prognosis. It is often metastatic at the time of presentation. Its relative rarity and histological resemblance to other tumors make it diagnostically challenging, requiring the need of immunohistochemistry and cytogenetics for definite diagnosis. Surgery is the mainstay of therapy with adjunct chemotherapy, although survival rates are very low.

Cerebral Small Vessel, But Not Large Vessel Disease, Is Associated With Impaired Cerebral Autoregulation During Cardiopulmonary Bypass: A Retrospective Cohort Study

BACKGROUND: Impaired cerebral blood flow (CBF) autoregulation during cardiopulmonary bypass (CPB) is associated with stroke and other adverse outcomes. Large and small arterial stenosis is prevalent in patients undergoing cardiac surgery. We hypothesize that large and/or small vessel cerebral arterial disease is associated with impaired cerebral autoregulation during CPB. METHODS: A retrospective cohort analysis of data from 346 patients undergoing cardiac surgery with CPB enrolled in an ongoing prospectively randomized clinical trial of autoregulation monitoring were evaluated. The study protocol included preoperative transcranial Doppler (TCD) evaluation of major cerebral artery flow velocity by a trained vascular technician and brain magnetic resonance imaging (MRI) between postoperative days 3 and 5. Brain MRI images were evaluated for chronic white matter hyperintensities (WMHI) by a vascular neurologist blinded to autoregulation data. "Large vessel" cerebral vascular disease was defined by the presence of characteristic TCD changes associated with stenosis of the major cerebral arteries. "Small vessel" cerebral vascular disease was defined based on accepted scoring methods of WMHI. All patients had continuous TCD-based autoregulation monitoring during surgery. RESULTS: Impaired autoregulation occurred in 32.4% (112/346) of patients. Preoperative TCD demonstrated moderate-severe large vessel stenosis in 67 (25.2%) of 266 patients with complete data. In adjusted analysis, female sex (odds ratio [OR], 0.46; 95% confidence interval [CI], 0.25–0.86; P = .014) and higher average temperature during CPB (OR, 1.23; 95% CI, 1.02–1.475; P = .029), but not moderate-severe large cerebral arterial stenosis (P = .406), were associated with impaired autoregulation during CPB. Of the 119 patients with available brain MRI data, 42 (35.3%) demonstrated WMHI. The presence of small vessel cerebral vascular disease was associated with impaired CBF autoregulation (OR, 3.25; 95% CI, 1.21–8.71; P = .019) after adjustment for age, history of peripheral vascular disease, preoperative hemoglobin level, and preoperative treatment with calcium channel blocking drugs. CONCLUSIONS: These data confirm that impaired CBF autoregulation is prevalent during CPB predisposing affected patients to brain hypoperfusion or hyperperfusion with low or high blood pressure, respectively. Small vessel, but not large vessel, cerebral vascular disease, male sex, and higher average body temperature during CPB appear to be associated with impaired autoregulation.

The Perioperative Management of Ascending Aortic Dissection

Acute aortic syndromes are a distinct group of pathologies involving the wall of the aorta that present acutely and can be potentially fatal unless treated in a timely fashion. The syndrome is dominated by aortic dissections, which comprise ≥95% of all such presentations. Those involving the ascending aorta are particularly lethal and require specific and early surgical treatment compared to dissections involving other parts of the aorta. The surgical repair of an ascending aortic dissection presents multiple challenges to the anesthesiologist. Thoughtful management throughout the perioperative period is critical for minimizing the significant morbidity and mortality associated with this condition. In this narrative review, we provide an overview of the perioperative management of patients presenting for the surgical repair of an ascending aortic dissection. Preoperative discussion focuses on assessment, hemodynamic management, and risk stratification. The intraoperative section includes an overview of anesthetic management, transesophageal echocardiographic assessment, and coagulopathy, as well as surgical considerations that may influence anesthetic management.

Cerebral Small Vessel, But Not Large Vessel Disease, Is Associated With Impaired Cerebral Autoregulation During Cardiopulmonary Bypass: A Retrospective Cohort Study

BACKGROUND: Impaired cerebral blood flow (CBF) autoregulation during cardiopulmonary bypass (CPB) is associated with stroke and other adverse outcomes. Large and small arterial stenosis is prevalent in patients undergoing cardiac surgery. We hypothesize that large and/or small vessel cerebral arterial disease is associated with impaired cerebral autoregulation during CPB. METHODS: A retrospective cohort analysis of data from 346 patients undergoing cardiac surgery with CPB enrolled in an ongoing prospectively randomized clinical trial of autoregulation monitoring were evaluated. The study protocol included preoperative transcranial Doppler (TCD) evaluation of major cerebral artery flow velocity by a trained vascular technician and brain magnetic resonance imaging (MRI) between postoperative days 3 and 5. Brain MRI images were evaluated for chronic white matter hyperintensities (WMHI) by a vascular neurologist blinded to autoregulation data. "Large vessel" cerebral vascular disease was defined by the presence of characteristic TCD changes associated with stenosis of the major cerebral arteries. "Small vessel" cerebral vascular disease was defined based on accepted scoring methods of WMHI. All patients had continuous TCD-based autoregulation monitoring during surgery. RESULTS: Impaired autoregulation occurred in 32.4% (112/346) of patients. Preoperative TCD demonstrated moderate-severe large vessel stenosis in 67 (25.2%) of 266 patients with complete data. In adjusted analysis, female sex (odds ratio [OR], 0.46; 95% confidence interval [CI], 0.25–0.86; P = .014) and higher average temperature during CPB (OR, 1.23; 95% CI, 1.02–1.475; P = .029), but not moderate-severe large cerebral arterial stenosis (P = .406), were associated with impaired autoregulation during CPB. Of the 119 patients with available brain MRI data, 42 (35.3%) demonstrated WMHI. The presence of small vessel cerebral vascular disease was associated with impaired CBF autoregulation (OR, 3.25; 95% CI, 1.21–8.71; P = .019) after adjustment for age, history of peripheral vascular disease, preoperative hemoglobin level, and preoperative treatment with calcium channel blocking drugs. CONCLUSIONS: These data confirm that impaired CBF autoregulation is prevalent during CPB predisposing affected patients to brain hypoperfusion or hyperperfusion with low or high blood pressure, respectively. Small vessel, but not large vessel, cerebral vascular disease, male sex, and higher average body temperature during CPB appear to be associated with impaired autoregulation.

Tranexamic Acid Dosing for Cardiac Surgical Patients With Chronic Renal Dysfunction: A New Dosing Regimen

BACKGROUND: Tranexamic acid (TXA) is a common antifibrinolytic agent used to minimize bleeding in cardiac surgery. Up to 50% cardiac surgical patients have chronic renal dysfunction (CRD). Optimal dosing of TXA in CRD remains poorly investigated. This is important as TXA is renally eliminated with accumulation in CRD. High TXA doses are associated with postoperative seizures. This study measures plasma TXA concentrations in CRD cardiac surgical patients for pharmacokinetic modeling and dose adjustment recommendations. METHODS: This prospective cohort study enrolled 48 patients with stages 1–5 CRD, classified by Kidney Disease Outcome Quality Initiative. Patients were separated into 2 treatment groups. A "low-risk" group underwent simple aortocoronary bypass or single-valve repair/replacement and received a 50 mg/kg TXA bolus. A "high-risk" group underwent redo, aortic, multiple valve or combination surgery and received the Blood Conservation Using Anti-fibrinolytics Trial dosing regimen (loading dose 30 mg/kg, infusion 16 mg/kg/h with 2 mg/kg in pump prime). Primary outcome identified changes in TXA clearance and distribution volume, which provided the rationale for dose adjustment. Descriptive clinical outcomes assessed postoperative seizures, blood loss, ischemic-thrombotic complications, in-hospital mortality, and length of hospital stay. RESULTS: TXA concentrations were elevated and sustained above the therapeutic threshold for approximately 12 hours in high-risk stages 3–5 groups, in accordance to CRD severity. CONCLUSIONS: Using a pharmacokinetic model, we propose a simple new TXA dosing regimen that optimizes maximal antifibrinolysis and avoids excessive drug dosing.

Effects of hypothermia during propofol anesthesia on learning and memory ability and hippocampal apoptosis in neonatal rats

Abstract

Objective

At present, the harm of hypothermia to the central nervous system has received a great attention from scholars. The present study aimed to investigate the effects of hypothermia on learning and memory abilities and hippocampal apoptosis in neonatal rats and the role of p-ERK and p-CREB in anesthesia.

Methods

In this study, 60 Sprague Dawley newborn rats (age 7-day-old) were randomly divided into 3 groups (n = 20), including Control Group (Group C), Anesthesia Group (Group A), and Anesthesia Hypothermia Group (Group AH). Group C was intraperitoneally injected with 0.1 ml saline, and rectal temperature was maintained in the range of 38–39 °C; Group A was intraperitoneally injected with 25 mg/kg of propofol (0.1 ml), the 1/2 initial dose was added per each period of 20 min, anesthesia was maintained for 2 h, and rectal temperature was kept in the range of 38–39 °C. The anesthesia mode and duration of Group AH were as same as Group A, room temperature was set to 23 °C, which caused body's temperature naturally dropped down. After the anesthesia recovered, each group randomly involved five rats for analyzing by Western blot to detect the expression level of p-ERK and p-CREB, and other five rates were also analyzed by flow cytometry assay to detect hippocampal apoptosis rate. The remaining 10 rats in each group were kept up to 30 days for conducting the Morris water maze test, five rats were tested for detecting the expression level of p-ERK and p-CREB, as well as hippocampal apoptosis rate in each group.

Results

Compared with Group C and Group A, the rectal temperature of Group AH was decreased significantly (P < 0.05); At the age of 7 days, compared with Group C and Group A, apoptosis rate of hippocampal tissue in Group AH was increased (P < 0.05), the expression level of p-ERK and p-CREB proteins in Group AH was significantly reduced (P < 0.05), and there were no significant differences between Group C and Group A. At the age of 36 days, there were no significant differences in the results of behavioral test, apoptotic rates, and expression level of the proteins.

Conclusion

Our findings suggest that hypothermia during anesthesia can increase the apoptosis rate in the hippocampus of neonatal rats, whose mechanism may be related to the downward adjustment of p-ERK and p-CREB. However, it has no obvious influence on the long-term learning and memory abilities.

Roles of inflammation, neurogenic inflammation, and neuroinflammation in pain

Abstract

Inflammation is the body's response to injury and infection, involving a complex biological response of the somatosensory, immune, autonomic, and vascular systems. Inflammatory mediators such as prostaglandin, proinflammatory cytokines, and chemokines induce pain via direct activation of nociceptors, the primary sensory neurons that detect noxious stimuli. Neurogenic inflammation is triggered by nerve activation and results in neuropeptide release and rapid plasma extravasation and edema, contributing to pain conditions such as headache. Neuroinflammation is a localized inflammation in the peripheral nervous system (PNS) and central nervous system (CNS). A characteristic feature of neuroinflammation is the activation of glial cells in dorsal root ganglia, spinal cord, and brain which leads to the production of proinflammatory cytokines and chemokines in the PNS and CNS that drives peripheral sensitization and central sensitization. Here, we discuss the distinct roles of inflammation, neurogenic inflammation, and neuroinflammation in the regulation of different types of pain conditions, with a special focus on neuroinflammation in postoperative pain and opioid-induced hyperalgesia.

Three versus five lumbar paravertebral injections for inguinal hernia repair in the elderly: a randomized double-blind clinical trial

Abstract

Purpose

The objective of the study was to compare three nerve stimulator-guided paravertebral injections versus five injections for elderly patients undergoing inguinal hernia repair in terms of the amount of intraoperative fentanyl and propofol consumption and conversion to general anesthesia. The secondary objective was postoperative pain.

Methods

A prospective, randomized, double-blind clinical trial was performed. 200 elderly patients undergoing unilateral herniorrhaphy were randomized into two groups. Group III received three PVB injections from T₁₂ to L₂ and placebo at T₁₁ and L₃. Group V received five PVB injections from T₁₁ to L₃.

Results

The mean intraoperative fentanyl and propofol consumption were significantly lower in group V (4.9 ± 7.2 µg versus 20.0 ± 12.9 µg and 5.7 ± 11.6 mg versus 34.6 ± 22.9 mg, respectively, p value < 0.0001). Five patients (5.0%) in group III had failed block and were converted to general anesthesia (p value = 0.024). Group V had significantly lower pain scores compared to group III during the first three postoperative days (p value < 0.0001).

Conclusion

The five PVB injection technique is more suitable as a sole anesthetic technique for elderly patients undergoing herniorrhaphy, since it required less intraoperative supplemental analgesia and provided lower postoperative pain scores compared to the three PVB injection technique.

Evaluating the psychometric properties of two-item and four-item short forms of the Japanese Pain Self-Efficacy Questionnaire: a cross-sectional study

Abstract

Purpose

The Pain Self-Efficacy Questionnaire is a valid measure assessing self-efficacy in individuals with chronic pain. Short-form versions of the measure have been developed to decrease the assessment burden. However, few studies have evaluated the psychometric properties of the short forms in languages other than English. The aim of this study was to evaluate two 2-item short forms and one 4-item short form of the Japanese Pain Self-Efficacy Questionnaire in terms of internal consistency, criterion validity, structural validity, and construct validity.

Methods

This was a cross-sectional study. Data from 150 individuals with mixed chronic pain at a pain management center in a university hospital were extracted from clinical records and analyzed. The data included the information of the original version and short forms of the Japanese Pain Self-Efficacy Questionnaire, and other pain-related measures assessing pain intensity, pain interference, anxiety, depression and pain catastrophizing.

Results

Item statistics supported the item selection for each of the three short forms. All the short forms demonstrated adequate internal consistency and criterion validity. With respect to construct validity, one of the 2-item short forms failed to meet the criterion regarding the change in the magnitude of correlation with a depression scale. The 4-item short form met all the criteria including structural validity.

Conclusion

The study findings provide evidence for the reliability and validity of 2- and 4-item versions of the Japanese Pain Self-Efficacy Questionnaire for use in clinical and research settings.

Relevance of peripheral cholinesterase activity on postoperative delirium in adult surgical patients (CESARO): A prospective observational cohort study

BACKGROUND The cholinergic system is considered to play a key role in the development of postoperative delirium (POD), which is a common complication after surgery. OBJECTIVES To determine whether peri-operative acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) activities are associated with the development of POD in in-hospital surgical patients, and raise hypotheses on cholinergic regulatory mechanisms in POD. DESIGN A prospective multicentre observational study by the Peripheral Cholinesterase-activity on Neurocognitive Dysfunctions in Surgical Patients (CESARO) study group. SETTING Nine German hospitals. PATIENTS Patients of at least 18 years of age scheduled for inpatient elective surgery for a variety of surgical procedures. A total of 650 patients (mean age 61.5 years, 52.8% male) were included. METHODS Clinical variables, and peripheral AChE and BuChE activities, were assessed throughout the peri-operative period using bedside point-of-care measurements (one pre-operative and two postoperative measurements). POD screening was conducted postoperatively for at least 24 h and up to the third postoperative day using a validated screening tool (nursing delirium screening scale). RESULTS In all, 179 patients (27.5%) developed POD within the early postoperative phase. There was a lower BuChE activity in patients with delirium compared with patients without delirium pre-operatively (Cohen's r = 0.07, P = 0.091), on postoperative day 1 (Cohen's r = 0.12, P = 0.003) and on postoperative day 2 (Cohen's r = 0.12, P = 0.002). In contrast, there was a significantly higher AChE activity in patients with delirium compared with patients without delirium pre-operatively (Cohen's r = 0.10, P = 0.012), on postoperative day 1 (Cohen's r = 0.11, P = 0.004) and on postoperative day 2 (Cohen's r = 0.13, P = 0.002). After adjusting for covariates in multiple logistic regression, a significant association between both BuChE and AChE activities and POD was not found. However, in the multivariable analysis using the Generalized Estimating Equation, cholinesterase activities showed that a decrease of BuChE activity by 100 U L−1 increased the risk of a delirium by approximately 2.1% (95% CI 1.6 to 2.8%) and for each 1 U g−1 of haemoglobin increase in AChE activity, there was a 1.4% (95% CI 0.6 to 2.2%) increased risk of POD. CONCLUSION Peri-operative peripheral cholinesterase activities may be related to the development of POD, but the clinical implications remain unclear. Further studies, in homogeneous patient groups with a strict protocol for measurement time points, are needed to investigate the relationship between cholinesterase activities and POD.

Goal-directed therapy during transthoracic oesophageal resection does not improve outcome: Randomised controlled trial

BACKGROUND Goal-directed therapy (GDT) is expected to be of highest benefit in high-risk surgery. Therefore, GDT is recommended during oesophageal resection, which carries a high risk of postoperative complications. OBJECTIVES The aim of this study was to confirm the hypothesis that GDT during oesophageal resection improves outcome compared with standard care. DESIGN A randomised controlled study. SETTING Two Swedish university hospitals, between October 2011 and October 2015. PATIENTS Sixty-four patients scheduled for elective transthoracic oesophageal resection were randomised. Exclusion criteria included colonic interposition and significant aortic or mitral valve insufficiency. INTERVENTION A three-step GDT protocol included stroke volume optimisation using colloid boluses as assessed by pulse-contour analysis, dobutamine infusion if cardiac index was below 2.5 l min−1 m−2 and norepinephrine infusion if mean arterial blood pressure was below 65 mmHg. MAIN OUTCOME MEASURE The incidence of complications per patient at 5 and 30 days postoperatively as assessed using a predefined list. RESULTS Fifty-nine patients were available for analysis. Patients in the intervention group received more colloid fluid (2190 ± 875 vs. 1596 ± 759 ml, P

Development of a prediction model for postoperative pneumonia: A multicentre prospective observational study

BACKGROUND Postoperative pneumonia is associated with increased morbidity, mortality and costs. Prediction models of pneumonia that are currently available are based on retrospectively collected data and administrative coding systems. OBJECTIVE To identify independent variables associated with the occurrence of postoperative pneumonia. DESIGN A prospective observational study of a multicentre cohort (Prospective Evaluation of a RIsk Score for postoperative pulmonary COmPlications in Europe database). SETTING Sixty-three hospitals in Europe. PATIENTS Patients undergoing surgery under general and/or regional anaesthesia during a 7-day recruitment period. MAIN OUTCOME MEASURE The primary outcome was postoperative pneumonia. Definition: the need for treatment with antibiotics for a respiratory infection and at least one of the following criteria: new or changed sputum; new or changed lung opacities on a clinically indicated chest radiograph; temperature more than 38.3 °C; leucocyte count more than 12 000 μl−1. RESULTS Postoperative pneumonia occurred in 120 out of 5094 patients (2.4%). Eighty-two of the 120 (68.3%) patients with pneumonia required ICU admission, compared with 399 of the 4974 (8.0%) without pneumonia (P
