RESUMEN
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.
RESUMEN
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.
RESUMEN
Pulmonary arteriovenous malformations (PAVMs) are rare vascular anomalies. Alternative designations are pulmonary arteriovenous fistulae or aneurysms. Although mostly asymptomatic, PAVMs can cause respiratory symptoms due to right-to-left shunt. The central nervous system is a potential target for complications, including stroke, as a result of paradoxical embolism. In this report, the authors describe an unusual case of cerebral emboli caused by paradoxical embolism through a PAVM, presenting with a broad pathology including orthodeoxia, central cyanosis and digital clubbing, which should be kept in mind since misdiagnosis may cause severe morbidity in young adults. LEARNING POINTS: Pulmonary arteriovenous fistulae, although rare, must be considered in the presence of dyspnoea, cyanosis, hypoxaemia/orthodeoxia and stroke.In young adults with embolic stroke of undetermined source (ESUS), paradoxical embolism has to be ruled out.Meticulous anamnesis and physical examination can guide diagnostic investigation, reducing hospitalization time and superfluous complementary examinations.
RESUMEN
The bacteremic spread of the sexually transmitted pathogen, Neisseria gonorrhoeae (N. gonorrhoeae), results in disseminated gonococcal infection (DGI), which can lead to a variety of clinical signs and symptoms, such as multiple skin lesions, tenosynovitis and arthralgias/arthritis. The Centers for Disease Control and Prevention listed that drug-resistant N. gonorrhoeae (cephalosporin resistance) poses an urgent threat due to antimicrobial resistance. The authors describe the case of a young woman presenting in the emergency department (ED) with skin lesions and malaise. DGI was confirmed by blood cultures, nucleic acid amplification testing (NAAT) in cervical mucosa and urine gonococcal probe. One week of intravenous ceftriaxone was administrated with complete clinical and analytical resolution. The patient made a full clinical recovery. Clinicians must be aware of the signs and symptoms of this rare yet reemerging disease.
