Insights

Familial Mediterranean Fever (FMF) can present with prolonged abdominal pain, lasting over a week. Early diagnosis and colchicine treatment are crucial for managing this rare clinical characteristic.

Area of Science:

  • Genetics
  • Internal Medicine
  • Rheumatology

Background:

  • Familial Mediterranean Fever (FMF) is an autoinflammatory disorder characterized by recurrent inflammatory episodes.
  • Abdominal pain and fever are common symptoms, typically resolving within 24-48 hours.

Observation:

  • A 50-year-old Japanese male presented with recurrent episodes of abdominal pain and fever since his late 20s.
  • His abdominal pain episodes lasted 1-2 weeks, significantly longer than the typical FMF presentation.
  • Immobility was necessary during episodes due to pain exacerbation with movement.

Findings:

  • Genetic analysis revealed MEFV gene exon 10 mutations (p.Met694Ile), confirming the FMF diagnosis.
  • Colchicine therapy proved effective in controlling the patient's FMF attacks.
  • The case highlights prolonged abdominal pain as an uncommon but possible clinical manifestation of FMF.

Implications:

  • Awareness of rare clinical presentations, such as prolonged abdominal pain, is essential for accurate FMF diagnosis.
  • Timely diagnosis and treatment, including colchicine, can improve patient quality of life.
  • Effective management of FMF is critical to prevent long-term complications like secondary amyloidosis.

Pericarditis II: Clinical features and Diagnostic Tests

Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...

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...

Increased Body Temperature

A body temperature above  38°C  (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Acute Pancreatitis II: Clinical Manifestations and Management

Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...
