A Rare Case of Rhabdomyolysis.

Rhabdomyolysis is a pathological condition presenting with symptoms of localized or generalized myalgia and weakness, associated with an increase in serum creatine kinase level and, often leading to myoglobinuria and acute kidney injury. It has a wide range of etiologies. Immune-mediated necrotizing myopathy (IMNM) is a rare type of inflammatory myopathy, that leads to rhabdomyolysis, and it is divided into three different subtypes: anti-3-hydroxy-3-methylglutaryl-coA reductase (anti-HMGCR, anti-signal recognition particle (anti-SRP), and seronegative. There are slight differences in incidence, age of onset, clinical course, and prognosis between these subtypes. We describe the case of a 67-year-old female with myalgias and weakness of the thighs for six weeks. Laboratory findings showed marked rhabdomyolysis and severe acute kidney injury. The workup led to the diagnosis of seronegative immune-mediated necrotizing myopathy (IMNM) and treatment with corticosteroid and methotrexate was introduced, which led to marked clinical improvement.

Epipericardial fat necrosis as a differential diagnosis of chest pain-A case report.

Epipericardial fat necrosis (EFN) is an uncommon self-limiting benign condition that can present with substantial chest pain. We present a case of an otherwise healthy 42-year-old man who presented with severe chest pain in the emergency department. Initial cardiopulmonary workup was unrevealing. Contrast-enhanced thorax CT demonstrated an increased radiolucency and nodularity of anterior pericardial fat consistent with epipericardial fat necrosis. The transthoracic echocardiogram was normal, and cardiac magnetic resonance imaging confirmed the lesion. Combined anti-inflammatory therapy was started with favorable evolution.

Acquired von Willebrand Syndrome and Chronic Anaemia: A Different Diagnostic Approach.

Heyde's syndrome is a form of acquired von Willebrand syndrome that consists of bleeding from intestinal angiodysplasia in the presence of aortic stenosis (AS). An association with obstructive hypertrophic cardiomyopathy, rather than AS, by a similar mechanism has also been described. We report the case of a 78-year-old woman with chronic anaemia and hypertrophic obstructive cardiomyopathy in whom intestinal angiodysplasia with active bleeding was identified by an unconventional method. In this case, the authors describe a different approach to reach the correct diagnosis. LEARNING POINTS: In patients with anaemia due to gastrointestinal bleeding, a high level of suspicion is crucial to identify the haemorrhagic focus.Intestinal angiodysplasia is associated with acquired von Willebrand syndrome.Acquired von Willebrand syndrome secondary to hypertrophic obstructive cardiomyopathy occurs by the same mechanism of aortic stenosis.

Foodborne Botulism: Neglected Diagnosis.

Botulism is rare neuroparalytic disease caused by botulinum toxin, one of the most toxic substances known. Foodborne botulism is caused by consumption of foods contaminated with botulinum toxin. The clinical manifestations are flaccid, symmetrical, descending paralysis affecting cranial and peripheral nerves. The only specific treatment is botulinum antitoxin. We report the case of a 37-year-old man with gastrointestinal manifestations and posterior cranial nerve palsy who was diagnosed with botulism infection. Clinicians should be aware of rare causes of infection and determine the aetiology of symptoms. LEARNING POINTS: Botulism remains a diagnostic challenge.Misdiagnosis of early cases suggests sporadic cases are overlooked.Timely clinical diagnosis is critical for treatment decisions as botulinum antitoxin cannot reverse existing paralysis.
