Proportion of urinary schistosomiasis among HIV-infected subjects in Benin city, Nigeria

This study aimed to determine the prevalence of urinary schistosomiasis, and the effect of CD4+T cell counts and demographics on its prevalence among HIV-positive patients in Benin City, Nigeria. Urine and blood samples were collected from 2000 HIV-positive subjects. A wet preparation of the urine deposit was examined microscopically to identify ova of Schistosoma haematobium. The blood specimens were analyzed using the flow cytometry for CD4+T-lymphocyte count. An overall prevalence rate of 0.3% was reported. Gender and CD4 count<200 cells/micro L did not affect the prevalence of urinary schistosomiasis, while HIV patients that were single had significantly higher prevalence of urinary schistosomiasis [p=0.002]. The prevalence of urinary schistosomiasis among HIV patients in Benin City is low. CD4+count did not affect the prevalence of urinary schistosomiasis

Hydatid cyst of urinary tract. Eleven cases at a single center

We retrospectively reviewed clinical records of 11 patients with hydatid cyst of the urinary tract admitted to our institution from 1998 to 2005. Hospital and follow-up records of 11 patients with hydatid cyst of the urinary tract were reviewed and data on the patients' symptoms and signs at presentation, radiological findings, diagnostic tests, pathologic findings, and surgical outcomes were reviewed. The chief complaint was flank pain in 7 patients [63.6%]. Hydaturia was not seen in any of our patients. Ten patients had renal involvement and 1 had a retrovesical hydatid cyst. Eosinophilia was detected in 2 of 11 patients who were tested. A positive indirect hemagglutination test was seen in 4 of 7 patients and a positive Casoni test in 1 of 2. Intravenous urography revealed caliceal distortion in 6 patients [54.5%], caliectasis in 3 [27.3%], and nonfunctioning kidney in 2 [18.2%]. Ultrasonography showed a complex cyst in all of the patients. Computed tomography demonstrated multivesicular cystic structure in 4 patients [36.4%], complex cyst in 4 [36.4%], and a simple cyst in 3 [27.3%]. Definite diagnosis was made only after surgical operation. We performed nephrectomy in 2 patients [18.2%], partial nephrectomy in 2 [18.2%], cystectomy plus marsupialization in 5 [45.4%], and retrovesical surgery in 1 [9.1%]. One patient refused surgical treatment. There was no perioperative major complication. Renal hydatidosis is a rare entity and the main challenge is preoperative diagnosis. Radiological and serologic studies, although indicative, cannot confirm the diagnosis, and only pathologic examination after surgical removal can confirm echinococcal infection

Incidencia de E coli en infecciones urinarias y su respuesta a los antimicrobianos (Experiencia del hospital San Gabriel 1994-1995) / Incidence of E. coli in urinary infection and antibacterial response (experience at San Gabriel Hospital)

Se realizo un estudio bacteriologico en muestras de orina de pacientes atendidos en el hospital San Gabriel durante el periodo comprendido entre mayo de 1994 a septiembre de 1995, cuyo diagnostico clinico fue ITU (infeccion del tracto urinario); de dichas muestras, 414 evidenciaron una bacteria como microorganismo causal. El estudio realizado, demuestra a E. coli como el agente causal mas frecuente en ITU (88.4 por ciento). Las pruebas de suceptibilidad a los distintos antimicrobianos demuestran una baja sensibilidad de E. coli a la ampicilina y al cotrimoxazol, antimicrobianos que frecuentemente se utilizan en nuestro medio para el tratamiento de ITU y cuyo estudio bacteriologico no siempre puede realizarse. Para la confirmacion estadistica de los resultados, se realizo la prueba Chi-cuadrado (X2), p< 0.05, cuyo resultado 13.08 indica que la elevada resistencia de E. coli a la ampicilina y al cotrimoxazol no se debe al azar, o a la casualidad sino mas bien a otros mecanismos que en el futuro deben investigarse. Cabe destacar la elevada sensibilidad de este microorganismo a antimicrobianos tales como: norfloxacina, acido pipemidico, nitrofuratoina, acido nalidixico, cefotaxima y gentamicina; lo cual concuerda con reportes internacionales previos

Schistosomiasis in a village in Assiut governorate: prevalence, intensity and urinary troubles

This work was done in El-Tawabya Village. Urine samples were collected from 3072 individuals. Results revealed that, prevalence rate of schistosomiasis infection was 7.5% and peak prevalence was among age group 10-14 years. Infection rate among males was nearly double [10.2%] that among females [5.6%]. Intensity of infection was of mild type [91.7%] and heavy infection occurred among those less than 30 years. The geometric mean of egg count of urinary schistosomiasis was 9.6 eggs/10 ml urine. Rate of infection was 15.3% among agricultural workers. As regards urinary symptoms, dysuria was found among 29.1%, turbid urine among 12.7%, terminal hematuria among 8.4% and total hematuria among only 0.5% and there is a significant relation between them and schistosomiasis infection. These symptoms had specificity of 74.2%, 90.5%, 95.7% and 99.9%, respectively. Microscopic urine examination showed that presence of RBCs with schistosomiasis infection had sensitivity of 89.2% and specificity of 80.6%
