[A Case of Penile Strangulation Due to Metal Rings Released with the Cooperation of a Rescue Team].

In this report, we describe a case of penile strangulation via metal rings. A 65-year-old Japanese man was transferred to the emergency room of our hospital for, dysuria and penile pain following penile incarceration with metal rings. Five metal rings approximately 30 mm in diameter were incarcerated to the penile root. Physical examination, revealed marked penile swelling distal to the rings. Various methods including the use of a ring cutter, were attempted to relieve the penial strangulation. However, these techniques failed, prompting referral to a rescue team. We started cutting the rings with an air cutter. After, 90 minutes, the rings were successfully removed. This study highlights the benefit of early cooperation with the rescue team in managing patients with mechanical penile strangulation.

[Well Leg Compartment Syndrome after Cystectomy in the Lithotomy Position: A Case Report].

Well leg compartment syndrome (WLCS) is an uncommon and severe complication that occurs after prolonged surgery in the lithotomy position. A 67-year-old male with bladder cancer who underwent cystectomy including ileal conduit construction in the lithotomy position developed severe, gradually worsening cramping pain in the right leg on the day after surgery. The posterior compartmental pressure of the right leg was high (40 mmHg), and WLCS was diagnosed. Emergency fasciotomy was followed by rehabilitation for one month and he recovered from motor or sensory deficits, but the pain continued. We considered that important factors associated with the development of WLCS in this patient were arteriosclerosis obliterans and the length of time during which he remained in the lithotomy position during the ileal conduit procedure. We consider thatlengthy surgical procedures for cystectomy with patients in the lithotomy position have high potential for inducing WLCS.

[Three Patients with Acute Myocardial Infarction Associated with Targeted Therapy of Sorafenib for Metastatic Renal Cell Carcinoma : Case Report].

Sorafenib is a tyrosine kinase inhibitor (TKI) of the vascular endothelial growth factor receptor (VEGFR) used for advanced renal cell carcinoma. Treatment with sorafenib prolongs progression-free survival in patients with advanced clear-cell renal cell carcinoma. However, in spite of its therapeutic efficacy, sorafenib causes a wide range of adverse events. Cardiovascular adverse events have been observed when sorafenib was used with targeted agents. Although these adverse events like hypertension, reduced left ventricular ejection fraction, cardiac ischemia or infarction were manageable with standard medical therapies in most cases, some had a poor clinical outcome. We report three cases of acute myocardial infarction associated with sorafenib in patients with metastatic renal cell carcinoma.
