[Three Cases of Bilateral Metachronous Testicular Tumors].

Polymyxin B and low-dose hydrocortisone treatment in a patient with uroseptic shock in a rural health unit.

Sepsis has a high mortality rate; thus, in the intensive care unit, early diagnosis and adjunctive treatments are crucial. However, generally, most patients with sepsis from rural area initially visit the emergency department at a rural hospital and are managed in general medical wards in Japan. Here we report on an 81-year-old Japanese female manifesting septic shock caused by the upper urinary tract infection of extended-spectrum beta-lactamase-producing secondary to the left ureter obstruction by the urothelial carcinoma.
