Abdominal surgery in patients with chronic noncirrhotic extrahepatic portal vein obstruction: A multicenter retrospective study.

Background And Aims: In patients with noncirrhotic chronic extrahepatic portal vein obstruction (EHPVO), data on the morbimortality of abdominal surgery are scarce.

Approach And Results: We retrospectively analyzed the charts of 76 patients (78 interventions) with EHPVO undergoing abdominal surgery within the Vascular Disease Interest Group network. Fourteen percent of the patients had ≥1 major bleeding (unrelated to portal hypertension) and 21% had ≥1 Dindo-Clavien grade ≥3 postoperative complications within 1 month after surgery.

Abundance and diversity of Culicoides Latreille (Diptera: Ceratopogonidae) in southern Ontario, Canada.

Background: Culicoides Latreille (Diptera: Ceratopogonidae) is a genus of hematophagous midges feeding on various vertebrate hosts and serving as a vector for numerous pathogens important to livestock and wildlife health. North American pathogens include bluetongue (BT) and epizootic hemorrhagic disease (EHD) viruses. Little is known about Culicoides spp.

Abdominal pain patterns during COVID-19: an observational study.

Abdominal pain and liver injury have been frequently reported during coronavirus disease-2019 (COVID-19). Our aim was to investigate characteristics of abdominal pain in COVID-19 patients and their association with disease severity and liver injury.Data of all COVID-19 patients hospitalized during the first wave in one hospital were retrieved.

New Distribution Records of Biting Midges of the Genus Culicoides (Diptera: Ceratopogonidae) Latreille, Culicoides bergi and Culicoides baueri, in Southern Ontario, Canada.

Some species of Culicoides Latreille (Diptera: Ceratopogonidae) can be pests as well as pathogen vectors, but data on their distribution in Ontario, Canada, are sparse. Collecting this baseline data is important given ongoing, accelerated alterations in global climate patterns that may favor the establishment of some species in northern latitudes. Culicoides spp.

Incidence of Hepatocellular Carcinoma in Patients With Nonalcoholic Fatty Liver Disease: A Systematic Review, Meta-analysis, and Meta-regression.

Background & Aims: Nonalcoholic fatty liver disease (NAFLD) may be a risk factor for hepatocellular carcinoma (HCC), but the extent of this association still needs to be addressed. Pooled incidence rates of HCC across the disease spectrum of NAFLD have never been estimated by meta-analysis.

Methods: In this systematic review, we searched Web of Science, Embase, PubMed, and the Cochrane Library from January 1, 1950 through July 30, 2020.

Rectal stump mucocele after a Hartmann's procedure causing mechanical ileus.

Two years after a Hartmann's procedure, an 85-year-old woman was admitted at our emergency department with abdominal bloating and severe constipation for 5 days. Abdominal CT showed a large rectal stump mucocele associated with compression of surrounding structures, causing a mechanical ileus and a bilateral pyelocaliceal dilatation. Successful transanal drainage with a rectal catheter allowed rapid recovery.

Surgical management of vascular Ehlers-Danlos syndrome and its challenges: a case report.

Background: Ehlers-Danlos syndrome (EDS) is a heterogeneous group of rare inherited diseases involving connective tissue. Vascular EDS (vEDS) is associated with abnormal type III collagen, which is an essential component of skin, hollow organs and arterial walls, and causes potentially fatal visceral and arterial complications. The surgical management of these patients is challenging and should be limited to life-saving procedures.

First case of Cryptococcus gattii multilobar pneumonia in Switzerland and associated challenges.

Background: Cryptococcosis is a frequent complication in immunosuppressed patients, causing mainly central nervous system and lung infection, and leading to increased mortality risk.

Case Presentation: We present the first documented case in Switzerland of Cryptococcus gattii pneumonia in a kidney-pancreas transplant patient, with a concomitant Pneumocystis jirovecii infection mimicking an immune reconstitution syndrome. Diagnosis of cryptococcal pneumonia was based on a positive serum cryptococcal antigen and confirmed by Grocott’s methenamine silver and periodic acid-Schiff stains on bronchoalveolar lavage fliud.

Introduction of a specialized consultation prior to insertion of totally implantable access venous devices: Impact on cancellation rate and patient satisfaction.

Objectives: Preoperative consultation is usually not performed before insertion of a totally implantable venous access device (TIVAD). In our experience, an incomplete preoperative assessment, a predictable medical condition contraindicating surgery, or no-show patients the day of surgery led to several surgery cancellations. Therefore, we introduced a specific preoperative surgical consultation for TIVAD that took place shortly before surgery.

Impact of an intra-abdominal cooling device during open kidney transplantation in pigs.

Background: Transplantation of kidneys from deceased donors is still associated with a high rate of postoperative renal dysfunction. During implantation into the recipient, the kidney rewarms. This second warm ischaemia time, which is not monitored, is harmful especially if prolonged.

Epizootic Hemorrhagic Disease in White-Tailed Deer, Canada.

Epizootic hemorrhagic disease affects wild and domestic ruminants and has recently spread northward within the United States. In September 2017, we detected epizootic hemorrhagic disease virus in wild white-tailed deer, Odocoileus virginianus, in east-central Canada. Culicoides spp.

Kidney transplantation, bioengineering and regeneration: an originally immunology-based discipline destined to transition towards ad hoc organ manufacturing and repair.

Kidney transplantation (KT), as a modality of renal replacement therapy (RRT), has been shown to be both economically and functionally superior to dialysis for the treatment of end-stage renal disease (ESRD). Progress in KT is limited by two major barriers: a) a chronic and burgeoning shortage of transplantable organs and b) the need for chronic immunosuppression following transplantation. Although ground-breaking advances in transplant immunology have improved patient survival and graft durability, a new pathway of innovation is needed in order to overcome current obstacles.

Clinical impact and cost of monitoring for asymptomatic laboratory abnormalities among patients receiving antiretroviral therapy in a resource-poor setting.

Background: Laboratory monitoring for toxicity among patients receiving antiretroviral therapy (ART) in less-developed settings is technically challenging and consumes significant resources.

Methods: We conducted a cohort study of the 1800 adult patients who initiated ART at the Haitian Study Group for Kaposi's Sarcoma and Opportunistic Infections (GHESKIO) in Haiti from 2003 to 2006, using baseline data to establish the prevalence and using follow-up data to establish the incidence of hepatitis, renal insufficiency, hyperglycemia, anemia, neutropenia, and thrombocytopenia. We determined how frequently routine (not symptom-driven) testing detected significant laboratory abnormalities and calculated the cost per disability-adjusted life year (DALY) averted by detection of these events in the asymptomatic stage, compared with a strategy of symptom-prompted testing only.

Pathogenic hantaviruses, northeastern Argentina and eastern Paraguay.

We describe the first, to our knowledge, cases of han-tavirus pulmonary syndrome in northeastern Argentina and eastern Paraguay. Andes and Juquitiba (JUQ) viruses were characterized. JUQV was also confirmed in 5 Oligoryzomys nigripes reservoir species from Misiones.

Genetic diversity, distribution, and serological features of hantavirus infection in five countries in South America.

Since 1995 when the first case of hantavirus pulmonary syndrome (HPS) was reported in Patagonia, there have been more than 400 cases of HPS reported in five countries in South America. The first case of HPS was associated with Andes (AND) virus. In this study, we report on the genetic diversity, geographical distribution, and serological features of hantavirus infection in six countries in South America based on 87 HPS cases from Argentina, Bolivia, Chile, Paraguay, and Uruguay.
