Gallbladder volvulus—acute cholecystitis ‘with a twist’

m_rjy303f01.png?Expires=1542705900&Signa

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

m_rjy307f01.png?Expires=1542705896&Signa

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.

Systematic Review of the Efficacy and Safety of Gabapentin and Pregabalin for Pain in Children and Adolescents

The barriers to opioid use in some countries necessitate the need to identify suitable alternatives or adjuncts for pain relief. The gabapentinoids (gabapentin and pregabalin) are approved for the management of persistent pain in adults, but not in children. Searches were conducted in Embase, Medline, Scopus, and Web of Science up until November 2017, for randomized controlled trials that investigated the analgesic effects of gabapentin or pregabalin in children and adolescents

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
