Fibrin immobilization vestibular extension (FIVE): A case series

paythelady.61 shared this article with you from Inoreader Fibrin immobilization vestibular extension (FIVE): A case series Via Clinical Implant Dentistry and Related Research Abstract Aims The objective of the present case series is to report on the rationale, surgical technique and outcome of a protocol for peri-implant mucosal phenotype modification therapy, referred to as "fibrin immobilization vestibular extension (FIVE)". Material and Methods The protocol utilized entailed apical positioning and stabilization of peri-implant flap with modular screws. The screws were also used for the immobilization of solid matrix platelet-rich fibrin to fill the gap created between apically positioned flap and the crestal margin of the flap. Results A total of 30 patients (12 male, 18 females) with 93 implants were treated with FIVE protocol for various indications, including for vestibular extension following alveolar ridge augmentation (N = 6), preprosthetic (N = 9), postprosthetic (N = 2), and peri-implantitis (N = 13). The keratinized mucosal width preoperatively was 1.67 mm with 95% confidence interval [CI] (1.46, 1.88). Immediately following FIVE surgery, the vestibule was extended to 9.10 with 95% CI (8.44, 9.76). At 3 months, 4.9 mm (95% CI: 4.5–5.2 mm) of peri-implant keratinized mucosal width was present. The keratinized mucosal width remained relatively stable thereafter and was 4.0 mm (95% CI: 3.5–4.5 mm) at 3 years post-FIVE surgery. When overall group means across all time points were analyzed, maxilla had mean of 6.1 mm (95% CI: 5.8–6.5) versus mandible exhibited mean of 5.1 mm (95% CI: 4.6–5.6 mm). The mean of maxilla was si gnificantly higher than that of the mandible (p < 0.0001) across all time points. Treatment of peri-implantitis with FIVE lead to significant pocket reduction and wide band of keratinized mucosa. Seven of 38 implants in 3 of 13 peri-implantitis patients were removed due to advanced peri-implantitis. Discussion The present case series provides proof-of-principle data for efficacy of FIVE for peri-implant phenotype modification therapy that generated attached keratinized mucosa in a variety of applications. This protocol provides an alternative to procedures involving harvesting of autogenous mucosal graft. View on the web Inoreader. Take back control of your news feed.

The efficacy of Kinesio taping on lymphedema following head and neck cancer therapy: a randomized, double blind, sham-controlled trial

a.sfakia shared this article with you from Inoreader The efficacy of Kinesio taping on lymphedema following head and neck cancer therapy: a randomized, double blind, sham-controlled trial Via swallowing exercises Physiother Theory Pract. 2022 Mar 28:1-15. doi: 10.1080/09593985.2022.2056862. Online ahead of print. ABSTRACT OBJECTIVE: The aim was to investigate the effectiveness of Kinesio taping for lymphedema following head and neck cancer therapy and its effect on patient compliance and quality of life. METHODS: A total of 66 patients with lymphedema following head and neck cancer therapy were randomly allocated to the therapeutic Kinesio taping group (n = 33) and the sham Kinesio taping group (n = 33). All participants received manual lymphatic drainage, Kinesio taping, and home exercises for the first four weeks, and only home exercises for the second four weeks. The tape measurements, a scale of external lymphedema, a scale of the internal ly mphedema, and quality of life were evaluated in both groups. The perceived discomfort consisting of limitation of daily living activities, pain, tightness, stiffness, and heaviness were also recorded. RESULTS: When the group x time effect was evaluated, it was observed that external lymphedema was significantly reduced in both groups according to neck and face composite measurements (p < .001). However, in these measurements, a significant difference was found between the groups in favor of the KT group (p = .001, p = .032, respectively). At the end of the study, there was no significant difference in terms of internal lymphedema in both groups (p = .860). The quality of life parameters such as global health status and swallowing were significantly better in the Kinesio taping group (p < .001). There was no significant difference in the parameters of perceived discomfort between the two groups (p = .282, p = .225, p = .090, p = .155, p = .183, respectively). CONCLU SION: Kinesio taping is effective in tape measurements and positively affects the quality of life in lymphedema following head and neck cancer therapy.

Classification of superficial lymphatic pathways in the upper extremity and incidence of lymphatic obstruction according to the lymphatic pathways in patients with unilateral upper extremity lymphedema

a.sfakia shared this article with you from Inoreader Classification of superficial lymphatic pathways in the upper extremity and incidence of lymphatic obstruction according to the lymphatic pathways in patients with unilateral upper extremity lymphedema Via Journal of plastic, reconstructive & aesthetic surgery : JPRAS J Plast Reconstr Aesthet Surg. 2022 Mar 2:S1748-6815(22)00133-4. doi: 10.1016/j.bjps.2022.02.049. Online ahead of print. ABSTRACT BACKGROUND: Indocyanine green (ICG) lymphography is frequently used in the diagnosis of lymphedema, as well as the planning of its surgical management, but the typical anatomy of the superficial lymphatic pathways is incompletely delineated. This study aims to evaluate the topographical anatomy of superficial lymphatic vessels of the upper extremity METHODS: Sixty consecutive patients undergoing lymphaticovenular anastomosis for unilateral upper extremity lymphedema were selected. Lymphatic mapping was performed on the normal contralateral arm with ICG lymphography. A single upper arm reference line and two separate forearm reference lines (anterior and posterior) were drawn between anatomic landmarks. Lymphatic pathways were analyzed based on distances (cm) from the reference lines and were compared with th ose in lymphedema arms. RESULTS: Mean age of the patients were 54.6 ± 8.4 years. Three lymphatic flow pathways were identified: anterior (100%), posterior (96.6%), and posterior-ulnar lymphatic (33.3%) vessels. The anterior and posterior lymphatic vessels ran along the anterior and posterior reference lines, respectively, on the forearm (within 2 cm) and medial to the upper arm reference line. In arms with lymphedema, the absence of lymphatic flow was most commonly observed in posterior lymphatics (29/59, 49%), followed by anterior (15/60, 25%) and posterior-ulnar lymphatics (1/20, 5%). Compared to normal arms, new lymphatic flow through posterior-ulnar lymphatics was observed in 34.5% of patients (10/29) in whom posterior lymphatics was completely obstructed. CONCLUSIONS: Superficial lymphatic vessels can be classified into anterior, posterior, and posterior-ulnar lymphatic vessels. Posterior-ulnar lymphatic vessels might be least affected by lymphosclerosis in patient s with lymphedema. PMID:35346607 | DOI:10.1016/j.bjps.2022.02.049 View on the web Inoreader.

Migration of a Fish Bone From the Esophagus to the Thyroid Gland

a.sfakia shared this article with you from Inoreader Migration of a Fish Bone From the Esophagus to the Thyroid Gland Via ear nose throat Ear Nose Throat J. 2022 Mar 29:1455613221086032. doi: 10.1177/01455613221086032. Online ahead of print. ABSTRACT Accidental swallowing of fish bone is one of the most common emergencies in the otolaryngology department. The impacted fish bones are usually found in the palatine tonsil, base of the tongue, valleculae, pyriform sinus, and esophagus, which can be successfully removed after a thorough examination. However, in some cases, the fish bone may penetrate into the neck soft tissue and migrate to extraluminal organs, causing infection, abscess formation, or rupture of vessels. In such cases, prompt recognition and immediate removal of the impacted fish bone are necessary. Herein, we report a rare case of a 60-year-old woman who had accidently swallowed a fish bone 10 days prior to visiting the outpatient department. The fiberoptic scope and head and neck computed tomography scans were obtained from the outpatient department. The fish bone was found to migrate from the upper esophagus to the left thyroid gland. First, a rigid esophageal endoscopy was performed in the operating room, but no obvious fish bone was noted over the esophagus. Finally, the fish bone was removed via exploratory cervicotomy with left-sided total lobectomy of the thyroid. The patient recovered after the operation, and there were no further complications during the 3 years of follow-up. PMID:35348022 | DOI:10.1177/01455613221086032 View on the web Inoreader.

A model to predict a risk of allergic rhinitis based on mitochondrial DNA copy number

a.sfakia shared this article with you from Inoreader A model to predict a risk of allergic rhinitis based on mitochondrial DNA copy number Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2022 Mar 29. doi: 10.1007/s00405-022-07341-7. Online ahead of print. ABSTRACT PURPOSE: To determine whether mitochondrial DNA copy number (mtDNA-CN) is associated with allergic rhinitis (AR), and further establish a nomogram model for the early diagnosis of AR. METHODS: We carried out a case-control study involving a total of 134 subjects, including 66 healthy controls and 68 AR patients. The mtDNA-CN in peripheral blood of all subjects was detected by real-time fluorescence quantitative polymerase chain reaction, and general information of patients was recorded. And, least absolute shrinkage selection operator (LASSO) regression was used to screen clinically significant variables, which were substituted into a logistic regression analysis to determine independent risk factors. Next, a nomogram model was developed for the risk prediction of AR. Then, internal validation was performed with the bootstrap resampling. Ultimately, the clinical benefit and validity of the nomogram were assessed by receiver operating characteristic (ROC) curve, bias-corrected curve, and decision curve analysis (DCA). RESULTS: MtDNA-CN and total IgE were determined as independent risk factors of AR. The final model achieved an area under the ROC curve (AUC) of 0.869, and the DCA curve demonstrated that the nomogram was clinically beneficial for practical application. CONCLUSION: An increase of the mtDNA-CN was linked to the occurrence risk of AR. The nomogram prediction model based on mtDNA-CN showed the potential clinical utility in improving risk prediction and providing new insights for exploring the pathogenesis of AR.

Prolactinoma

a.sfakia shared this article with you from Inoreader Prolactinoma Via Otolaryngologic Clinics of North America Prolactinomas are the most common secretory tumor of the pituitary gland. Clinical symptoms may be due to prolactin oversecretion, localized mass effect, or a combination of both. Although the mainstay of prolactinoma management is medical therapy with dopamine agonists, endoscopic endonasal or transcranial surgery, radiation therapy, or a combination of these is an important treatment option in select cases. This article discusses prolactinoma phenotypes, clinical presentations, and clinically pertinent medical and surgical considerations when managing these tumors. View on the web Inoreader.

Acromegaly

a.sfakia shared this article with you from Inoreader Acromegaly Via Otolaryngologic Clinics of North America Acromegaly results from excessive secretion of insulinlike growth factor-1 and growth hormone, which most commonly occurs because of pituitary somatotrophinoma. Diagnostic features of acromegaly include elevated insulinlike growth factor-1 and growth hormone; lesion on brain MRI; and clinically dysmorphic features, such as soft tissue swelling, jaw prognathism, and acral overgrowth. Transsphenoidal resection is the primary therapy for individuals with acromegaly, even in the cases where gross total resection is not possible because of parasellar extension and cavernous sinus involvement. For recurrent or persistent disease after resection, systemic medications and stereotactic radiosurgery are used. View on the web Inoreader. Take back control of your news feed.

Giant Pituitary Adenoma – Special Considerations

a.sfakia shared this article with you from Inoreader Giant Pituitary Adenoma – Special Considerations Via Otolaryngologic Clinics of North America Giant pituitary adenomas (GPAs) comprise 5% to 15% of pituitary adenomas, but have higher rates of extrasellar invasion, subtotal resection, surgical morbidity, and recurrence. With the possible exception of giant prolactinomas, GPAs require surgical decompression. On review of 3 decades of case series encompassing 699 microsurgical transsphenoidal (MT), 1060 endoscopic endonasal trans-sphenoidal (EET), and 513 transcranial (TC) patients, gross total resection and recurrence rates were comparable across modalities, but the EET approach had lower perioperative mortality and superior restoration of visual function. Each approach has unique indications. Combined EET-TC approaches for minimizing residual tumor represent another area of study. View on the web Inoreader. Take back control of your news feed.

Improvement of performance and function in respiratory protection equipment using nanomaterials

xlomafota.13 shared this article with you from Inoreader Improvement of performance and function in respiratory protection equipment using nanomaterials Via Latest Results for Journal of Nanoparticle Research Abstract Nanotechnology has become one of key areas for the current development and research. Nanotechnology focuses on matter at the nanoscale and is capable of using different approaches to produce nanomaterials, structures, devices, and systems. One of the concerns that have to be addressed is the adverse effects of exposure to pathogens and pollutants in different workplaces and environments. Respiratory protective equipment (RPE) is one of the personal protective equipment (PPE) utilized to reduce the risk of exposure to environmental or occupational respiratory hazards. Thus, various studies have been conducted for improving the functional properties of sorbents or filters in different kinds of RPE. Different categories of nanomaterials have been reported as effective agents for achieving this goal. The application of these nanomaterials in mask layers or respirators' cartridge could significantly increase the filtration efficiency, breathing comfort, and antiba cterial/antiviral properties of the masks and respirators. The present study aimed to comprehensively review the nanomaterials used in different types of face RPE with emphasis on various properties of the utilized nanomaterials. The study also aimed to show an applied perspective for future research on this important subject. Graphical abstract View on the web Inoreader. Take back control of your news feed.

The contralateral progression in a cohort of Chinese adult patients with unilateral moyamoya disease after revascularization: a single-center long-term retrospective study

xlomafota.13 shared this article with you from Inoreader The contralateral progression in a cohort of Chinese adult patients with unilateral moyamoya disease after revascularization: a single-center long-term retrospective study Via Latest Results for Acta Neurochirurgica Abstract Background Moyamoya disease (MMD) is a chronic progressive cerebrovascular disease mainly existing in the Asian population, which can be divided into unilateral and bilateral types. Contralateral progression has been reported in pediatric patients with unilateral MMD, while large series about contralateral progression in Chinese adult patients were rare. The goal of this study is to elucidate the clinical features and incidence of contralateral progression in Chinese MMD adult patients. Methods One hundred one Chinese adult patients with unilateral MMD who received surgery treatments between January 2015 and January 2017 in our hospital were enrolled in this study. This study contained 89 patients. Digital subtraction angiography was performed in all patients for initial diagnosis, and magnetic resonance angiography was repeated 6 months from the initial operation and then annually. Clinical characteristics, contralateral progression, and risk factors were studied. Previous related studies were also reviewed and meta-analyzed. Results Of these 89 patients, contralateral progression was identified in 8 patients (9.0%) within a median follow-up period of 63 months, which was lower than that in previous studies (25.9%). Single-factor analysis and multivariate analysis did not reveal significant risk factors related to the contralateral progression. Conclusion The progress rate in this cohort of Chinese adult patients with unilateral MMD after revascularization was 9.0%, which indicates that some of the unilateral MMD were an early form of bilateral MMD rather than a separate condition.
