Povidone-iodine sclerotherapy is ineffective in the treatment of symptomatic renal cysts.

PURPOSE: To evaluate the efficacy of povidone-iodine sclerotherapy after percutaneous drainage of simple renal cysts in the treatment of symptomatic patients. PATIENTS AND METHODS: Sixteen patients with symptomatic renal cysts were treated by percutaneous drainage and injection of povidone-iodine solution. The cysts were drained by a nephrostomy tube catheter, and povidone- iodine injections were repeated every 24 hours for 3 days. All patients were followed up by ultrasound examination during a period ranging from 1 to 4 years (mean 1.8 years). RESULTS: Thirteen patients experienced recurrence of cysts, while complete resolution was observed in only three patients. Of the cysts that recurred, only partial resolution in cyst diameter was observed (from 3-10.5 cm to 2.4-8.6 cm). During the follow-up period, 12 of the 16 patients (75%) continued to have pain that necessitated additional treatments. CONCLUSION: Povidone-iodine sclerotherapy is followed by a high rate of recurrence and is therefore not indicated for the treatment of symptomatic simple renal cysts.

Herpes simplex virus type 2 seropositivity in a sexually transmitted disease clinic in Israel.

BACKGROUND: Seroepidemeliogic surveys have provided valuable information on the prevalence and incidence of herpes simplex virus-2 infection in general and in selected populations. OBJECTIVE: To review the reliability of traditional diagnostic approaches in herpes simplex virus-2 infection. METHODS: In this cross-sectional study, 472 patients attending a clinic for sexually transmitted disease in 1998-1999 were evaluated for HSV-2 infection through collection of epidemiologic and clinical data. HSV-2 infection was confirmed by the presence of specific viral glycoprotein, gG-2, antibody in sera. RESULTS: The seroprevalence of HSV-2 among clinic attendees was 9.33%. Of these attendees only 22% presented with or reported a history of typical vesicular lesions in the genital area. Infection rate was higher in patients with multiple sex partners (20.8% vs. 8.7%, P < or = 0.0023), in individuals aged 30 or older (12.6 vs. 6.4%, P = 0.03) and in the Israeli Jewish population as compared to the Israeli Arab population (11.1% vs. 2.4%, P < or = 0.01). Females with multiple sex partners exhibited higher rates of infection than did their male counterparts (50 vs. 16.1%, P < or = 0.0275). CONCLUSION: The findings support the need for HSV-2 serologic testing in patients presenting to STD clinics even when typical genital lesions are not evident but where risk factors for HSV-2 infection are identified.

Candida albicans colonization of dental plaque in elderly dysphagic patients.

BACKGROUND: Dysphagia is a common disorder among the elderly population. As many as 50% of nursing home residents suffer from dysphagia. It is important to identify patients at increased risk for colonization of dental and denture plaque by pathogenic organisms in order to prevent associated disease. OBJECTIVES: To quantify the prevalence and evaluate the effect of dental and denture plaque colonization by Candida albicans in hospitalized elderly dysphagic patients as a complication of stroke, as well as the effect of systemic antimicrobial therapy on C. albicans colonization in these patients. METHODS: We evaluated dysphagia and antibiotic therapy as risk factors for dental and denture plaque colonization by C. albicans in elderly stroke rehabilitating patients with dysphagia, as compared to elderly non-dysphagic stroke and non-stroke rehabilitating patients on days 0, 7 and 14 following admission to the Fliman Geriatric Rehabilitation Hospital. RESULTS: The risk of C. albicans colonization of dental plaque was greater in dysphagic patients than in those without dysphagia on day 0 (50% vs. 21%, P = 0.076), day 7 (58 vs. 15.2%, P = 0.008) and day 14 (58 vs. 15.2%, P = 0.08). Similarly, patients on antibiotic therapy were at greater risk for C. albicans colonization of dental plaque on day 0 (56 vs. 11%, P = 0.002), day 7 (44 vs. 14.8%, P = 0.04) and day 14 (39 vs. 19%, P = 0.18). The risk of C. albicans colonization of denture plaque as opposed to dental plaques in non-dysphagic patients was significantly greater on day 0 (45.7 vs. 21.2%, P = 0.03), day 7 (51.4 vs. 15.1%, P = 0.0016) and day 14 (54.3 vs. 15.1%, P = 0.0007). Dysphagia did not increase the risk of denture plaque colonization by C. albicans. CONCLUSIONS: Both dysphagia and antibiotic therapy are risk factors for C. albicans colonization of dental plaque, and although dysphagia does not significantly increase colonization of denture plaque, denture wearers are at greater risk of such colonization.

Medical management of Crohn's disease.

The clinical course of Crohn's disease (CD) is characterized by unpredictable phases of disease activity and quiescence. The majority of CD patients experience mild to moderate disease or are in clinical remission over significant periods during the course of their disease. These patients can be treated conservatively with 5-aminosalicylates or budesonide depending on the disease location. Those patients with more severe forms of the disease who require corticosteroids should be treated more aggressively with early introduction of immunomodulator and/or biologic therapy, which may help to prevent the complications associated with CD. It has been suggested that therapies directed at mucosal healing may favorably modify the natural history of CD. As newer, more effective medications become available and new therapeutic approaches are introduced (top-down therapy), mucosal healing, and not solely clinical remission, may well become the preferred treatment objective.

Metastatic breast cancer to the bladder: a diagnostic challenge and review of the literature.

Nineteen cases of breast cancer metastatic to the bladder and diagnosed in living patients have been identified in the English literature. Most patients were symptomatic with evidence of disseminated disease at the time of diagnosis. Metastasis usually occurred many years after diagnosis, and the prognosis was poor. The definitive modality for diagnosis in all cases was cystoscopy, which demonstrated an abnormal lesion in the bladder wall that was confirmed on biopsy. In our study, we discuss the case of a patient with breast cancer metastatic to the bladder despite a normal cystoscopic evaluation.
