A Case of Hepatitis B Reactivation with Acute Flare Three Months After Tenofovir Prophylaxis Withdrawal in a Allogenic Hematopoietic Stem Cell Transplantation Patient

Hepatitis B virus (HBV) infection is a major health problem worldwide. HBV reactivation is associated with high mortality rates in hematopoietic stem cell transplantation (HSCT) and, prophylactic antiviral treatment is suggested to prevent this phenomenon. However, the duration of antiviral treatment in HSCT patients is not fully defined and the time of immune recovery is considered the best parameter for a drug to be safely interrupted. We aimed to present a case of hepatitis B reactivation after cessation of one-year prophylactic tenofovir treatment in a anti-hepatitis B core immunoglobulin G-positive patient who received allogenic HSCT treatment for chronic lymphocytic leukemia

Immunosuppressive therapy and the risk of hepatitis B reactivation: Consensus report

This consensus report includes expert opinions and recommendations regarding the screening, and if necessary, the follow-up, prophylaxis, and treatment of hepatitis B before the treatment in patients who will undergo immunosuppressive therapy due to the risk of hepatitis B reactivation emergency. To increase awareness regarding the risk of hepatitis B reactivation in immunosuppressive patients, academicians from several university health research and training centers across Turkey came together and discussed the importance of the subject, current status, and issues in accordance with the current literature data and presented solutions

Is Gastric Xanthelasma an Alarming Endoscopic Marker for Advanced Atrophic Gastritis and Intestinal Metaplasia?

Gastric xanthelasma(s) is a warning endoscopic sign for the presence of multifocal atrophic gastritis and advanced intestinal metaplasia

A secure communication using cascade chaotic computing systems on clinical decision support

Clinical decision support systems (C-DSS) provide supportive tools to the expert for the determination of the disease. Today, many of the support systems, which have been developed for a better and more accurate diagnosis, have reached a dynamic structure due to artificial intelligence techniques. However, in cases when important diagnosis studies should be performed in secret, a secure communication system is required. In this study, secure communication of a DSS is examined through a developed double layer chaotic communication system. The developed communication system consists of four main parts: random number generator, cascade chaotic calculation layer, PCM, and logical mixer layers. Thanks to this system, important patient data created by DSS will be conveyed to the center through a secure communication line

Biliary Endoscopic Sphincterotomy: Techniques and Complications

Biliary endoscopic sphincterotomy (EST) refers to the cutting of the biliary sphincter and intraduodenal segment of the common bile duct following selective cannulation, using a high frequency current applied with a special knife, sphincterotome, inserted into the papilla. EST is either used solely for the treatment of diseases of the papilla of Vater, such as sphincter of Oddi dysfunction or to facilitate subsequent therapeutic biliary interventions, such as stone extraction, stenting, etc. It is a prerequisite for biliary interventions, thus every practitioner who performs endoscopic retrograde cholangiopancreatography needs to know different techniques and the clinical and anatomic parameters related to the efficacy and safety of the procedure. In this manuscript, we will review the indications, contraindications and techniques of biliary EST and the management of its complications.PubMedWoSScopu
