ENDOSCOPIC SHIELDING OF RECTOURETHRAL FISTULA AFTER LAPAROSCOPIC RADICAL PROSTATECTOMY; REPORT OF A CASE.

Rectourethral fistulais a relatively rare complication of radical prostatectomy but is extremely difficult to treat. We report a case with post-laparoscopic radical prostatectomy rectourethral fistula, treated with only endoscopic shielding.A 75-year-old man had undergone laparoscopic radical prostatectomy for prostate cancer, cT2cN0M0. Although there was no finding of rectal injury during the operation, pneumaturia, pyuria and diarrhea appeared at postoperative day 21 and diagnosed rectourethral fistula by colonoscopy and amidotrizoic acid enema. The fistula did not close spontaneously. Four months after the prostatectomy, we treated with endoscopic shielding by use of polyglycolic acid sheets and fibrin glue. The fistula have not recurred for 20 months after the endoscopic procedure.This method is simple and less-invasive for patients. We think it is worth trying this method before surgical management for narrow rectourethral fistula following radical prostatectomy.

Acute Monocytic Leukemia Masquerading Behçet's Disease-Like Illness at Onset in an Elderly Female.

A previously healthy 74-year-old Japanese female was hospitalized with fever and high C-reactive protein. She developed palatal herpangina-like aphthous ulcers, localized intestinal wall thickening, terminal ileum ulcers, and an erythematous acneiform rash; thus Behçet's disease-like illness was suspected. Significant peripheral blood acute monocytosis developed during her hospitalization and acute monocytic leukemia (FAB M5b) with normal karyotype was diagnosed. By immunostaining, the infiltrating cells in the skin and the terminal ileum were identified as monocytic leukemic cells. This case exhibited a unique initial presentation of Behçet's disease-like illness associated with acute monocytic leukemia.

Opportunistic Infections in Patients with HTLV-1 Infection.

As an acquired immunodeficiency, human immunodeficiency virus (HIV) infection is primarily responsible for opportunistic infections in infected patients. However, opportunistic infections also occur in individuals with human T cell lymphotrophic virus type 1 (HTLV-1) infection. Here, we report opportunistic infections in two Japanese HTLV-1-seropositive patients. The first patient was a 67-year-old male, who had cytomegalovirus infection associated with esophagogastritis and terminal ileitis. The patient was HTLV-1-positive and was diagnosed with smoldering adult T cell leukemia (ATL). High levels of serum soluble IL-2 receptor (sIL-2R; 4,304 U/mL) and an increased percentage of CD4+CD25+ T cells (75.5%) in peripheral blood were also detected. The second patient was a 78-year-old female, a known asymptomatic HTLV-1 carrier, who presented with persistent herpes zoster, followed by Pneumocystis jirovecii pneumonia. Disease progression of smoldering ATL along opportunistic infections was observed with very high levels of serum sIL-2R (14,058 U/mL) and an increased percentage of CD4+CD25+ T cells (87.2%) in peripheral blood. In patients with suspected opportunistic infections, both HTLV-1 and HIV should be considered. In HTLV-1-positive patients, an increase in the CD4+CD25+ T cell subset may have its value as a prognostic marker.
