Normal dietary consumption and absorption of copper exceed the metabolic need, and homeostasis of this element is maintained exclusively by the biliary excretion of copper. Wilson’s disease is an inherited disorder in which defective biliary excretion of copper leads to its accumulation, particularly in liver and brain. Continue reading “Diagnostic Scoring System for Wilson’s Disease”
Portal hypertension is the haemodynamic abnormality associated with the most severe complications of cirrhosis, including ascites, hepatic encephalopathy and bleeding from gastroesophageal varices. Variceal bleeding is a medical emergency associated with a mortality that, in spite of recent progress, is still in the order of 10–20% at 6 weeks. The evaluation of diagnostic tools and the design and conduct of good clinical trials for the treatment of portal hypertension have always been difficult.

Evaluation and management of Covid-19 depend on the severity of the disease. Patients with mild disease usually recover at home, whereas patients with moderate disease should be monitored closely and sometimes hospitalized.

Invasive fungal diseases (IFDs) remain important causes of morbidity and mortality. The consensus definitions of the Infectious Diseases Group of the European Organization for Research and Treatment of Cancer and the Mycoses Study Group have been of immense value to researchers who conduct clinical trials of antifungals, assess diagnostic tests, and undertake epidemiologic studies. Continue reading “Criteria for Proven Invasive Fungal Disease”
IgG4-related disease is characterized by a high level of serum IgG4 and dense infiltration of IgG4-positive plasma cells into multiple organs, with the kidney being one representative target. Although several sets of diagnostic criteria for autoimmune pancreatitis (AIP) are available and renal lesion is recognized as an extrapancreatic manifestation of AIP, it is difficult to differentiate IgG4-related tubulointerstitial nephritis (TIN) without
AIP from other types of TIN. Continue reading “Diagnostic Criteria for IgG4-Related Kidney Disease (IgG4-RKD)”
Immunoglobulin G4-related disease is an immune mediated condition resulting in disease in various organs of the body such as the pancreas, kidneys, salivary glands, lung, liver, lymph nodes, biliary tract and orbits of the eyes. The disease is recognized by a characteristic pattern of pathological, serological or clinical features shared amongst the organs system that are involved. In some cases, IgG4-RD can mimic malignant, infectious or inflammatory disorders and therefore distinguishing the disease is crucial. Continue reading “Classification Criteria for IgG4-Related Disease”
Metabolic dysfunction-associated fatty liver disease (MAFLD) is a new concept proposed in 2020. Unlike non-alcoholic fatter liver disease (NAFLD), the diagnosis of MAFLD requires the presence any of the following 3 metabolic risks, including overweight/obesity, presence of diabetes mellitus, and evidence of metabolic dysregulation. Continue reading “Diagnosis of Metabolic Dysfunction-Associated Fatty Liver Disease (MAFLD)”
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a newly identified pathogen and it is assumed there is no pre-existing human immunity to the virus. Initial seroconversion, including neutralizing antibodies, has been documented and there is some evidence that immunity to SARS-CoV-2 re-challenge during early convalescence is likely. Continue reading “Case Definition for Coronavirus Disease 2019 (COVID-19)”
Autosomal dominant polycystic kidney disease (ADPKD) is the most common inherited cause of kidney disease. Enlarging cysts within the kidneys are the clinical hallmark of the disease. Renal manifestations include varying degrees of kidney injury, urinary tract infections, kidney stones, and hematuria. Extrarenal manifestations can include pain, hypertension, left ventricular hypertrophy, hepatic cysts, intracranial aneurysm, diverticulosis, and abdominal and inguinal hernias. Continue reading “New Diagnostic Criteria Proposed for Polycystic Kidney Disease”
There is currently no vaccine to prevent coronavirus disease 2019 (Covid-19).
The best way to prevent illness is to avoid being exposed to this virus. Continue reading “Prevention of Coronavirus Disease (Covid-19)”
