Haemophagocytic lymphohistiocytosis (HLH) secondary to disseminated histoplasmosis infection in a patient with HIV.

A male in his 30s who was recently diagnosed with HIV arrived at the emergency department exhibiting an altered mental state and acute respiratory distress. Initial laboratory tests revealed a high anion gap metabolic acidosis, elevated liver enzyme levels and bicytopenia. A CT scan identified a miliary pattern.

ANCA vasculitis: A manifestation of Post-Covid-19 Syndrome.

The SARS-CoV-2 infection has been found to present with different degrees of response and variable levels of inflammation. Patients who have recovered from the initial infection can develop long-term symptomatology. We present a unique case of a middle aged-healthy man who developed complications of ANCA-associated vasculitis after recovering from a mild COVID-19 infection.

Atypical Presentation of Acute Disseminated Encephalomyelitis (ADEM) in a Middle-Aged Adult.

BACKGROUND Acute disseminated encephalomyelitis (ADEM) is a demyelinating disease that usually presents in pediatric patients, usually following a viral or bacterial infection. The clinical findings in ADEM include acute neurologic decline that typically presents with encephalopathy, with some cases progressing to multiple sclerosis. An atypical case of ADEM is reported that presented in a middle-aged adult.

Epstein-Barr-positive classical Hodgkin lymphoma-associated haemophagocytic lymphohistocytiosis: a rare case.

Haemophagocytic lymphohistiocytosis (HLH) is a life-threatening condition, which is usually triggered by autoimmune disorders, viral infections and malignancy, like lymphomas. We present a 60-year-old Hispanic woman with a medical history of hypertension and systemic lupus erythematosus presenting with fever, generalised weakness and shortness of breath for 3 weeks. She was hypotensive on presentation, and a CT scan of abdomen/chest showed multiple irregular hepatic and splenic hypodense lesions.

Cardiomyopathy induced by anabolic-androgenic steroid abuse.

Bodybuilders use anabolic-androgenic steroids to increase muscle mass, but abuse of these hormones has been related to cardiomyopathy in the past. A 60-year-old Caucasian male bodybuilder with medical history of male hypogonadism and on testosterone replacement therapy, allegedly preparing for a weightlifting competition and receiving stem cell infusions from his trainer, is transferred to the intensive care unit for worsening shortness of breath after failing treatment for community-acquired pneumonia. Chest X-ray on transfer was suggestive of pulmonary oedema, and transthoracic echocardiography showed an ejection fraction of 25%-30%.

A case of posterior reversible encephalopathy syndrome associated with sepsis.

Posterior reversible encephalopathy syndrome (PRES) is a neurological disorder characterised by parieto-occipital vasogenic oedema seen on MRI. Infection and sepsis has been reported as a possible cause for this disorder.We present a 19-year-old immunocompetent Caucasian man with known type 1 diabetes mellitus who presented to the emergency department with acute onset of bilateral visual loss, headaches and hypertension; he had been discharged 2 weeks ago for severe diabetic ketoacidosis and bacteraemia.

Headache in an HIV-Positive Patient: Dangerous Interaction.

Ergotism is an ischaemic complication due to vasoconstriction throughout the body due to ingestion of ergotamine. A 34-year-old Hispanic man with HIV infection treated with saquinavir, ritonavir and abacavir/lamivudine presented to the emergency department complaining of left foot pain 1 week prior to admission. The affected extremity was cold with absence of pedal and tibial pulses.

Disseminated Nocardiosis Associated with Treatment with Infliximab in a Patient with Ulcerative Colitis.

BACKGROUND Opportunistic infections may occur when patients with inflammatory bowel disease (IBD) are treated with tumor necrosis factor (TNF)-alpha inhibitors. With the increasing use of new immunosuppressant drugs, the incidence of opportunistic or atypical infections is also increasing, including with Nocardia spp. A high level of awareness of atypical infections is warranted in immunosuppressed patients.

Complement activation: an atypical presentation of an atypical syndrome.

A 42-year-old Hispanic female and long-distance runner was seen for evaluation of fatigue. Her physical examination showed petechiae and ecchymoses in upper extremities, abdominal distension and bilateral ankle oedema. Laboratory workup revealed anaemia, thrombocytopenia, hypoalbuminemia and proteinuria of 1.
