Review Case Reports
Intracranial Hemorrhaging Following Cardiobacterium hominis Endocarditis.
Acute infectious endocarditis (IE) is a complex disease that presents as a serious clinical condition associated with a high mortality rate, especially due to intracranial hemorrhaging (ICH). The most common causative organism is Staphylococcus aureus. ⋯ A review of the existing literature revealed that acute IE associated with Cardiobacterium has been reported to cause ICH in only seven previous cases. Prolonged culture-specific antibiotic therapy along with extended surveillance of blood culture is therefore essential for timely intervention.

A 63-year-old man presented with persistent cough and progressive dyspnea. Computed tomography showed irregular pleural thickening and fibrotic changes with volume loss in the upper lobes, and subtle reticulation in the lower lobes. Pleuroparenchymal fibroelastosis (PPFE) was diagnosed based on the findings of a surgical lung biopsy. ⋯ A usual interstitial pneumonia (UIP) pattern was also observed in the lower lobes. Three weeks after the biopsy, an acute exacerbation occurred. We herein describe a rare case of idiopathic PPFE with various bronchiolar lesions and a UIP pattern in which an acute exacerbation developed.

Ewing's sarcoma (ES)/primitive neuroectodermal tumors (PNETs) are highly malignant neoplasms that usually affect the bones and soft tissues in children and young adults. ES/PNET of the lung is very rare and is associated with a poor prognosis. ⋯ He was started on pazopanib, which resulted in a five-month progression-free survival. To our knowledge, this is the first demonstration of pazopanib efficacy in ES/PNET of the lung.

Immunotherapy targeting programmed cell death-1 (PD-1) signaling is becoming the standard of care for advanced gastric cancer. We herein report a patient with gastric adenocarcinoma with peritoneal dissemination who was treated with nab-paclitaxel and ramucirumab following nivolumab and developed sclerosing cholangitis. ⋯ Thereafter, the administration of fourth-line chemotherapy with nab-paclitaxel and ramucirumab following nivolumab resulted in a clinical response. Nivolumab may enhance the efficacy of the subsequent chemotherapy regimens but also induce sclerosing cholangitis.

Objective Renal arteriolosclerosis is a risk factor for acute reductions in the glomerular filtration rate (GFR) when renin-angiotensin system (RAS) inhibitors are administered. Renal arteriolosclerosis can be detected by an increase in the resistive index (RI) on Doppler ultrasonography. The purpose of the present study is to determine whether or not the RI can predict acute GFR reductions following RAS blockade in chronic kidney disease (CKD). ⋯ A univariate Cox proportional-hazards analysis showed that the RI, age, GFR, systolic blood pressure, urinary protein excretion, diabetic kidney disease, coronary artery disease, and use of diuretics were significant variables. Multivariate hazard ratios were calculated from the RI and three established variables (age, GFR, diuretics), and the RI and use of diuretics were shown to be significant risk factors for acute GFR reductions. Conclusion These results suggest that an increase in the RI, as well as the use of diuretics, may be risk factors for acute GFR reductions following RAS blockade.
