Acute graft-versus-host disease of the gut
Abstract:
A 28-year-old man with acute promyelocytic leukemia at first early relapse received HLA-matched allogenic bone marrow transplantation (BMT) at first early relapse. Cyclosporin A and methotrexate were administered at conventional doses as a prophylaxis for graft-versus-host disease (GVHD). He presented with severe bloody diarrhea on day 87 after BMT. Examination of the lower gastrointestinal tract revealed diffuse mucosal change of inflammation. A diagnosis of late onset of acute gut GVHD was made, in the absence of other manifestations such as skin and liver involvement. A further survey is needed to clarify the incidence and the pathogenesis of atypical gut GVHD.

Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
Acute Respiratory Failure-I
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...
Acute Respiratory Failure-II
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:
