A Case of Organizing Pneumonia Associated with FOLFIRI Chemotherapy.

The combination chemotherapy of irinotecan with 5-fluorouracil and leucovorin (FOLFIRI regimen) was recently proven to be beneficial in patients with advanced colorectal cancer. Pulmonary toxicity is very rare in adverse effects of irinotecan. No case of organizing pneumonia (also known as bronchiolitis obliterans organizing pneumonia) associated with FOLFIRI chemotherapy has been reported. We experienced a case of a 62-year-old man who presented persistent dry cough and progressive dyspnea after receiving chemotherapy with FOLFIRI regimen. After surgical lung biopsy, the patient was diagnosed with FOLFIRI chemotherapy-induced organizing pneumonia which was successfully treated with steroid therapy.

A case of shoshin beriberi presenting as cardiogenic shock with diffuse ST-segment elevation, which dramatically improved after a single dose of thiamine.

Shoshin beriberi is a fulminant form of cardiac beriberi caused by thiamine deficiency. We report on a case of an 87-year-old man with shoshin beriberi presenting as cardiogenic shock with diffuse ST-segment elevation, which dramatically improved after thiamine administration. Because of the rarity of the occurrence, lack of diagnostic test and atypical presentation, diagnosing shoshin beriberi is challenging and requires a high index of clinical suspicion. Shoshin beriberi leads to rapid haemodynamic collapse and death. Therefore, clinicians should consider shoshin beriberi (or cardiac beriberi) as one of the differential diagnoses in patients with heart failure or cardiogenic shock.
