[Three Cases of Bilateral Metachronous Testicular Tumors].

We present three cases of bilateral metachronous testicular tumors. The patient in case 1 had a history of left orchiectomy for undescended testis at the age of 19. The pathological findings revealed germ cell neoplasia in situ. Twenty-four years later (age＝43), he was diagnosed with right testicular tumor with lymph node and lung metastasis (stage IIIc). Right orchiectomy was performed, and the pathological finding showed nonseminomatous germ cell tumor. He underwent chemotherapy, followed by lymph node dissection and lung metastasectomy. The patient in case 2 had a history of left orchiectomy for testicular tumor at the age of 41. The pathological finding of the left testis revealed seminoma (stage IA). Nineteen years later (age＝60), he was diagnosed with right testicular tumor and underwent right orchiectomy. Herein, the pathological finding showed seminoma (stage IA). The patient in case 3 had a history of right orchiectomy for testicular tumor at the age of 25. The pathological findings revealed seminoma (stage IS), and he underwent adjuvant radiation of the para-aortic field without subsequent recurrence. Fourteen years later (age＝39), he was diagnosed with left testicular tumor and underwent left orchiectomy. The pathological finding revealed seminoma (stage IB). The patient underwent adjuvant carboplatin monotherapy to prevent recurrence. Due to the long interval between the occurrence of bilateral metachronous testicular tumors (mean＝19 years ; three cases), long-term observation is necessary to detect the possible occurrence of contralateral testicular tumors. Contralateral testicular biopsy might be considered at the time of orchiectomy for unilateral testicular tumor if associated with testicular atrophy and/or a history of undescended testis.

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 Escherichia coli secondary to the left ureter obstruction by the urothelial carcinoma. Broad-spectrum antibiotics were administered. Although critical for the source control of infection, drainage of the ureteropelvic junction could not be performed immediately because of catecholamine-resistant hypotension. Hence, we administered polymyxin B-immobilized fiber column direct hemoperfusion, followed by low-dose hydrocortisone administration. After 8 hours of infusion, she recovered from the septic shock and successfully underwent emergency percutaneous nephrostomy. This presented strategy may provide a new resolution of catecholamine-resistant patients in urosepsis.
