Disseminated histoplasmosis progressive extrapulmonary infectio...

Acute Disseminated Encephalomyelitis (ADEM) is a monophasic demyelinating disease most often triggered by infection or immunization, though associations with malignancy and stem cell transplant have been described. We described the case of a four-year-old boy with new-onset neurological symptoms associated with ADEM, acute leukemia, and equivocal evidence of Mycoplasma pneumoniae infection. He ...

Mycobacterium bolletii is a rapidly growing nontuberculous mycobacterium first characterized in 2006. Here, we report a case of disseminated infection caused by M. bolletii in a young adult patient. To our knowledge, this is the first case of disseminated M. bolletii infection in an otherwise healthy young adult.

Disseminated herpes simplex virus (HSV) and varicella zoster virus (VZV) have been reported individually in immunosuppressed adults. We present a case of coinfection with disseminated HSV and VZV infection in a patient taking thalidomide for relapsed multiple myeloma. This is the first report of opportunistic infection associated with thalidomide.

Malakoplakia in an acquired immunodeficiency syndrome (AIDS) patient with disseminated Mycobacterium simiae infection presented with a large pelvic mass that caused organ dysfunction from mimicking a tumor. Malakoplakia is a rare, chronic granulomatous abnormal host response toward infectious agents, presenting as a tumor-like lesion. This is the first report of pelvic malakoplakia after dissem...

Disseminated neonatal herpes simplex virus (HSV) infection is characterized by progressive multiple organ failure and high mortality rates. It can result from infection with either HSV-1 or HSV-2. We report a case of disseminated neonatal herpes that was caused by HSV-1 and HSV-2.

Eight patients with AIDS and Pneumocystis carinii infection were studied. Protean manifestations were a feature not untypical of disseminated pneumocystosis. Aerosolised pentamidine as prophylaxis against P carinii pneumonia was ineffective at suppressing dissemination. The knowledge that extrapulmonary infection can occur has implications for the detection and treatment of, and prophylaxis aga...

Acute disseminated encephalomyelitis is a demyelinating disease, typically occurring in children following a febrile infection or a vaccination. Primary and secondary immune responses contribute to inflammation and subsequent demyelination, but the exact pathogenesis is still unknown. Diagnosis of acute disseminated encephalomyelitis is strongly suggested by temporal relationship between an inf...

introduction cryptococcosis is an opportunistic fungal infection mostly in immunocompromised patients. here we present the immunocompetent case with crypotoccosis. case presentation a 60-year-old man without any history of immunodeficiency or major risk factor of fungal infection, referred to the emergency department with systemic symptoms and low back pain. the patient’s condition gradually de...
