Insights

Mitochondrial Myopathy Encephalopathy, Lactic Acidosis with Stroke-like episodes (MELAS) can initially present with gastrointestinal issues like abdominal pain and vomiting. This case highlights the importance of considering metabolic disorders even when symptoms seem unrelated to typical neurological or muscular presentations.

Area of Science:

  • Neurology
  • Genetics
  • Gastroenterology

Background:

  • Mitochondrial disorders, such as MELAS, often manifest with neurological or myopathic symptoms.
  • Visceral symptoms are common in mitochondrial diseases but rarely the primary presenting feature.

Observation:

  • A patient presented with abdominal pain and vomiting, initially misdiagnosed as gastro-oesophageal reflux.
  • Detailed clinical history revealed the possibility of an underlying metabolic defect.

Findings:

  • The patient was diagnosed with Mitochondrial Myopathy Encephalopathy, Lactic Acidosis with Stroke-like episodes (MELAS) syndrome.
  • The molecular defect underlying the condition was identified.

Implications:

  • This case underscores the need to consider rare metabolic disorders in patients with atypical gastrointestinal presentations.
  • Early suspicion and investigation of MELAS can lead to timely diagnosis and management.
  • Recognizing diverse clinical presentations of MELAS is crucial for accurate diagnosis.

Pathophysiology of Vomiting01:22

Pathophysiology of Vomiting

Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through interaction...

Acute Pancreatitis I: Introduction

Acute pancreatitis is the sudden inflammation of the pancreas caused by the early activation of digestive enzymes, leading to the autodigestion of pancreatic tissue. This results in local inflammation and, in severe cases, systemic complications.EtiologyUnderstanding the underlying causes is crucial, as identifying the etiology guides treatment and anticipates complications. Acute pancreatitis can be triggered by various factors, typically grouped into the following clinical categories.Biliary...
Acute Pancreatitis I: Introduction01:27

Acute Pancreatitis I: Introduction

Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
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:
Appendicitis-I: Introduction01:22

Appendicitis-I: Introduction

The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...
Mitochondrial Membranes01:45

Mitochondrial Membranes

A single mitochondrion is a bean-shaped organelle enclosed by a double-membrane system. The outer membrane of mitochondria is smooth and contains many porins - the integral membrane transporters. Porins enable free diffusion of ions and small uncharged molecules through the outer mitochondrial membrane but limit the transport of molecules larger than 5000 Daltons. Further, the outer mitochondrial membrane forms a unique structure called membrane contact sites with other subcellular organelles,...
