Objective This study explored the prognostic factors of in-hospital mortality in patients with Pneumocystis pneumonia (PCP) without human immunodeficiency virus (HIV) infection, using a Japanese nationwide inpatient database. Methods We extracted the data of patients with PCP without HIV infection between July 2010 and March 2022 from the Diagnosis Procedure Combination database. We performed multivariable logistic regression analyses to identify the prognostic factors of in-hospital mortality in with PCP without HIV infection. ⋯ Higher in-hospital mortality was associated with advanced age, male sex (odds ratio [OR], 1.45; 95% confidence interval [CI], 1.06-2.00), a low Barthel index score, non-hematological malignancy (OR, 1.81; 95% CI, 1.22-2.70), receipt of mechanical ventilation (OR, 2.49; 95% CI, 1.47-4.21), and administration of antibiotics (OR, 1.52; 95% CI, 1.12-2.06) and antifungal drugs (OR, 1.83; 95% CI, 1.26-2.67). Lower in-hospital mortality was associated with connective tissue disease and vasculitis (OR, 0.55; 95% CI, 0.37-0.81), hematological malignancy (OR, 0.59; 95% CI, 0.38-0.93), and early trimethoprim-sulfamethoxazole treatment (OR, 0.63; 95% CI, 0.44-0.90). Conclusions These findings will help physicians identify patients who may benefit from early aggressive therapeutic interventions.

A 76-year-old woman with persistent diarrhea was referred to our hospital. She had purpura, peripheral eosinophilia (18,177/μL), and an elevated serum IgG4 level (819 mg/dL). Abdominal computed tomography revealed massive ascites and bowel edema. ⋯ Biopsies of the gastrointestinal mucosa revealed dense eosinophilic infiltration, indicating eosinophilic gastroenteritis (EG) associated with the hypereosinophilic syndrome. The number of IgG4-positive cells increased in the duodenal mucosa; however, the diagnostic criteria for IgG4-related disease (IgG4-RD) were not met. Whether or not EG with ascites is a manifestation of IgG4-RD warrants further investigation.

Exercise-associated hyponatremia (EAH) is a life-threatening dilutional hyponatremia that typically occurs during or immediately after exercise in endurance athletes. A 49-year-old actress experienced dizziness 15 min after a 2-h stage performance while drinking several bottles of water. ⋯ After initial treatment with 3% saline, her sodium levels immediately increased, and she recovered consciousness without developing subsequent osmotic demyelination syndrome. This case emphasizes the need for caution against excessive fluid intake during and/or after exercise to avoid EAH, even in non-athletes.

A 73-year-old man with a history of heterotaxy syndrome and intestinal malrotation developed hemorrhagic shock due to bleeding from a duodenal ulcer. Esophagogastroduodenoscopy failed to achieve hemostasis because of restriction of the view by massive hemorrhage. Transcatheter arterial embolization cannot achieve endovascular hemostasis due to the vascular anatomy. ⋯ Intestinal malrotation due to heterotaxy syndrome is a risk factor for gastrointestinal bleeding. Severe gastrointestinal bleeding in patients with intestinal malrotation is difficult to control with endoscopy alone. Therefore, combined therapies with endoscopy, interventional radiology, surgical procedures, and intensive care are vital for achieving a better prognosis.
