RESUMO
Ventricular fibrillation and cardiac arrest rarely occur after local application of epinephrine. Local and superficial application of epinephrine is a common hemostatic method during bronchoscopy, especially after biopsies. Although high plasma levels following endobronchial application of epinephrine have been observed in previous animal studies, there is no report of ventricular fibrillation after a usual dose of endobronchial application of epinephrine during bronchoscopy. We present a case of endobronchial epinephrine-induced ventricular fibrillation and cardiac arrest in a 31-year-old man with no previous history of cardiac disease.

Hemophagocytic lymphohistiocytosis (HLH) is a rare disease with a high mortality rate. It is associated with a variety of bacterial, viral, fungal, and parasitic infections. In the literature, there are several cases of HLH associated with scrub typhus in adults, all of which were successfully treated with antibiotic therapy for scrub typhus. This report describes a case of HLH accompanied by scrub typhus in an 81-year-old woman, in whom the disease progressed despite doxycyclin therapy. The patient refused to receive immunosuppressive chemotherapy for HLH and died 5 weeks after admission due to multi-organ failure. To our knowledge, this is the first case of death due to scrub typhus-associated HLH in an adult.

Follicular dendritic cells (FDC) are non-lymphoid, non-phagocytic accessory cells of the immune system and these cells are essential for antigen presentation and regulation of the reactions in germinal centers. Follicular dendritic cell sarcoma (FDCS) is a rare neoplasm that shows a low-to-intermediate malignant potential. The most commonly involved sites are the lymph nodes, but FDCS may also occur at a variety of extranodal sites, including the oral cavity, tonsils, gastrointestinal tract and liver. We describe here a 79-year-old woman who had FDCS with extensive lymph node involvement, dry cough, and an itching sensation. The patient improved after systemic chemotherapy.

Infective endocarditis caused by Pasteurella multocida is a rare disease with a high mortality rate. Most patients have a previous history of animal contact. The most common comorbid condition is a chronic liver disease, which is attributable to the high mortality rate. Over half of the patients who survived the disease had required valve replacement surgery. We report the case of a 70-year-old man diagnosed with prosthetic valve endocarditis caused by Pasteurella multocida and complicated with multiple peripheral arterial embolism. He had neither any underlying immunocompromising diseases nor previous history of animal contact. He was successfully cured after antibiotic therapy for 6 weeks without valve replacement surgery.
