Binge-eating and sodium bicarbonate: a potent combination for gastric rupture in adults-two case reports and a review of literature.

Background: Disordered eating behaviour including binge-eating often results in significant medical conditions, which are at times fatal. It can result in acute gastric dilatation which can lead to ischemic necrosis and stomach rupture. Dyspepsia and bloating are common symptoms following binge eating.

Laparoscopic choledochotomy and choledochoduodenostomy for the management of persistent common bile duct stones.

Choledochotomy and choledochoduodenostomy were commonly used technique in the early twentieth century to extract bile duct stones. Endoscopic retrograde cholangiopancreatography and sphincterotomy revolutionised the scenario and is currently the preferred first-line option for managing choledocholithiasis. However, in certain circumstances, where endoscopic retrograde cholangiopancreatography fails, choledochotomy and choledochoduodenostomy are the only available options.

Life-threatening gastrointestinal haemorrhage requiring surgical resection caused by SARS-CoV-2 induced ANCA associated vasculitis: A case report.

Introduction And Importance: SARS-CoV-2 infection has been linked to the diagnosis of various autoimmune conditions as well as flares in pre-existing disease. With such high prevalence of SARS-CoV-2 in the community, it is important to consider rare manifestations of autoimmune conditions when patients present with severe symptoms. Multi-specialty care is required to ensure optimal outcomes and prompt diagnosis.

Portal vein stenting in the management of duodenal varices due to malignant obstruction: A case report and literature review.

Introduction And Importance: Ectopic varices of the small bowel are a rare complication of portal hypertension. There are various aetiologies that can cause portal vein hypertension such as portal vein obstruction. Each of these pathologies has their own management strategies.

Case series on high grade appendiceal cancer with peritoneal and liver carcinomatosis undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC).

Background: Pseudomyxoma Peritonei (PMP) is a mucin producing cancer with appendix as primary site. Cytoreductive Surgery (CRS) combined with hyper-thermic intraperitoneal chemotherapy (HIPEC) is an established form of therapy known to prolong survival in patients with PMP and peritoneal carcinomatosis. Methods/patients In our case series, we present five cases of PMP with synchronous liver and peritoneal metastasis treated with CRS and HIPEC.

Incidental adenocarcinoma of the gallbladder in a patient with Y insertion gallbladder duplication in the context of recurrent biliary colic: A video case report.

Rationale: Gallbladder cancer is the most common malignancy of the biliary tree. Despite this, the only curative therapy remains surgical resection of the lesion achieving microscopically clear margins before malignant spread has occurred. Gallbladder duplication is an uncommon anatomical variance which occurs globally.

A very rare case report of an iatrogenic bladder perforation in a young female with concurrent Fitz-Hugh-Curtis syndrome.

Acute bladder injuries are rare and usually occur following significant amount of trauma. It has also been reported to occur in patients with chronic conditions like carcinoma, prolonged indwelling catheters, chronic infections of the bladder among others. We present a case of an otherwise fit and healthy young woman who presented to our emergency department following an episode of binge drinking and urinary retention.

Robotic resection of a multicystic tailgut cyst.

A 29-year-old woman with recurrent pelvic pain that progressed post partum was diagnosed with a multicystic pararectal lesion on ultrasound and CT scan. Physiology was conducted to establish a preoperative function and pudendal nerve integrity. The lesion was resected using a Da Vinci Xi robotic system.

Very rare case of synchronous volvulus of the sigmoid colon and caecum causing large-bowel obstruction.

Large-bowel obstruction caused by volvulus is potentially life threatening if not managed promptly. Sigmoid colon is the most common site of volvulus followed by caecum. Synchronous double colonic volvulus is an exceedingly rare entity, with only five cases published previously.

Passivation of Germanium by Graphene.

The oxidation of Ge covered with graphene that is either grown on or transferred to the surface is investigated by X-ray photoelectron spectroscopy, Raman spectroscopy, and transmission electron microscopy. Graphene properly grown by chemical vapor deposition on Ge(100), (111), or (110) effectively inhibits room-temperature oxidation of the surface. When graphene is transferred to the Ge surface, oxidation is reduced relative to that on uncovered Ge but has the same power law dependence.

Triplet exciton dissociation and electron extraction in graphene-templated pentacene observed with ultrafast spectroscopy.

We compare the ultrafast dynamics of singlet fission and charge generation in pentacene films grown on glass and graphene. Pentacene grown on graphene is interesting because it forms large crystals with the long axis of the molecules "lying-down" (parallel to the surface). At low excitation fluence, spectra for pentacene on graphene contain triplet absorptions at 507 and 545 nm and no bleaching at 630 nm, which we show is due to the orientation of the pentacene molecules.

Effects of confinement, surface-induced orientations and strain on dynamical behaviors of bacteria in thin liquid crystalline films.

We report on the organization and dynamics of bacteria (Proteus mirabilis) dispersed within lyotropic liquid crystal (LC) films confined by pairs of surfaces that induce homeotropic (perpendicular) or hybrid (homeotropic and parallel orientations at each surface) anchoring of the LC. By using motile vegetative bacteria (3 µm in length) and homeotropically aligned LC films with thicknesses that exceed the length of the rod-shaped cells, a key finding reported in this paper is that elastic torques generated by the LC are sufficiently large to overcome wall-induced hydrodynamic torques acting on the cells, thus leading to LC-guided bacterial motion near surfaces that orient LCs. This result extends to bacteria within LC films with hybrid anchoring, and leads to the observation that asymmetric strain within a hybrid aligned LC rectifies motions of motile cells.

Evolution, kinetics, energetics, and environmental factors of graphene degradation on silicon dioxide.

Recent studies have qualitatively shown that the oxidative stability of monolayer graphene integrated on oxides is relatively poor. Here, the evolution, kinetics, and energetics of this degradation are quantified. Specifically, the deterioration of graphene on SiO2 is studied in grain interiors and at grain boundaries in ambient air, dry air and nitrogen between 473 and 673 K, using spatially and temporally resolved in situ Raman spectroscopy in addition to electron microscopy and charge transport measurements.

Observing electron extraction by monolayer graphene using time-resolved surface photoresponse measurements.

Graphene is considered a next-generation electrode for indium tin oxide (ITO)-free organic photovoltaic devices (OPVs). However, to date, limited numbers of OPVs containing surface-modified graphene electrodes perform as well as ITO-based counterparts, and no devices containing a bare graphene electrode have been reported to yield satisfactory rectification characteristics. In this report, we provide experimental data to learn why.

Semiconducting carbon nanotube aerogel bulk heterojunction solar cells.

Using a novel two-step fabrication scheme, we create highly semiconducting-enriched single-walled carbon nanotube (sSWNT) bulk heterojunctions (BHJs) by first creating highly porous interconnected sSWNT aerogels (sSWNT-AEROs), followed by back-filling the pores with [6,6]-phenyl-C(71)-butyric acid methyl ester (PC(71)BM). We demonstrate sSWNT-AERO structures with density as low as 2.5 mg cm(-3), porosity as high as 99.

Highly stretchable carbon nanotube transistors with ion gel gate dielectrics.

Field-effect transistors (FETs) that are stretchable up to 50% without appreciable degradation in performance are demonstrated. The FETs are based on buckled thin films of polyfluorene-wrapped semiconducting single-walled carbon nanotubes (CNTs) as the channel, a flexible ion gel as the dielectric, and buckled metal films as electrodes. The buckling of the CNT film enables the high degree of stretchability while the flexible nature of the ion gel allows it to maintain a high quality interface with the CNTs during stretching.

Staff Satisfaction in the Functionalisation of Psychiatric In-patient Care.

In many UK mental health services, in-patient psychiatric care is being separated from community care by having dedicated in-patient medical team. We evaluated staff satisfaction in this functionalised in-patient care. A survey was conducted amongst multidisciplinary staff from various teams using a questionnaire survey.
