Which anaesthesia should be recommended for prostate biopsy / ¿Qué Anestesia debe Recomendarse para la Biopsia de la Próstata?

OBJECTIVE: Although transrectal ultrasound-guided prostatic biopsies are associated with significant discomfort and pain, most urologists do not use any kind of anaesthesia. We therefore compared the efficacy of two local anaesthetics, namely, the rectal administration of lidocaine gel and lidocaine periprostatic infiltration prior to biopsies. DESIGN AND METHODS: Three hundred and fifty-six randomized patients received either 15 mL of 2 lidocaine gel administered intrarectally ten minutes before prostate biopsies in group 1 (180 patients) or 10 mL of 1 lidocaine given under ultrasound guidance in two periprostatic injections of 5 mL, four minutes before the biopsies in group 2 (176 patients). A visual analogue scale (VAS) was used to assess the pain score during anaesthesia (VAS 1), during the biopsies (VAS 2) and 30 minutes after them (VAS 3). RESULTS: Patients receiving lidocaine gel experienced statistically less pain than the lidocaine injection group for mean VAS 1 (0.1 vs 1.4, p < 0.0001) and mean VAS 3 (0.8 vs 1.4, p < 0. 001) but VAS 2 showed no statistically significant difference (2.0 vs 2.1). No major morbidity was noted with either anaesthetic. CONCLUSION: Rectal administration of lidocaine gel is both safe, simple and effective and results are more satisfactory than with lidocaine periprostatic infiltration

Objetivo: Aunque las biopsias prostáticas transrectales guiadas mediante ultrasonido se asocian con considerable malestar y dolor, la mayoría de los urólogos no usa cualquier tipo de anestesia. Por lo tanto, comparamos la eficacia de dos anestésicos locales, a saber, la administración rectal de gel de lidocaína y la infiltración con lidocaína del área periprostática antes de las biopsias. Diseño y métodos: Trescientos cincuenta y seis pacientes randomizados recibieron o bien 15 mL de lidocaína en gel al 2%, administrada intrarectalmente diez minutos antes de las biopsias de la próstata en el grupo 1 (180 pacientes); o alternativamente 10 mL de lidocaína al 1% administrada bajo la guía de ultrasonido en dos inyecciones periprostáticas de 5 mL, cuatro minutos antes de las biopsias en el grupo 2 (176 pacientes). Se usó una escala analógica visual (EAV) para evaluar el grado de dolor durante la anestesia (EAV 1), durante las biopsias (EAV 2) y 30 minutos después de realizarlas (EAV 3). Resultados: Los pacientes que recibieron lidocaína en gel, experimentaron menos dolor estadísticamente, que el grupo de la inyección de lidocaína, para la VAS 1 media (0.1 frente a 1.4, p <0.0001) y VAS 3 media (0.8 frente a 1.4, p <0.001). Sin embargo, la VAS 2 no mostró diferencia significativa alguna en términos estadísticos (2.0 frente a 2.1). No se vio morbosidad de consideración con ninguno de los anestésicos. Conclusión: La administración rectal de gel de lidocaína es tan segura y simple como efectiva, y siendo los resultados más satisfactorio que aquellos producidos con la infiltración periprostática de lidocaína..

Retrospective review of leptospirosis in Guadeloupe, French West Indies 1994-2001 / Revisión retrospectiva de la leptospirosis en Guadalupe, Indias Occidentales Francesas 1994­2001

Demographic, clinical, biological and personal data were obtained from patients hospitalized with symptoms of leptospirosis in the Hospital of Pointe a Pitre, Guadeloupe, French West Indies from 1994 to 2001. Of the 897 screened patients, 212 were acute cases, 607 were non-infected and 78 were undetermined cases. There was no predominant age group. Leptospirosis transmission followed the rainfall cycle and was greater in rural areas. Jaundice and conjunctival suffusion were significantly more frequent in cases than non-cases. Males, professions considered to be at risk and contact with swine or bovine were associated with infection. Serogroups Icterohaemorrhagiae, Cynopteri, Australis, Sejroe, Pomona and Ballum were serovars presumed responsible for acute cases

Se obtuvieron los datos demográficos, clínicos, biológicos y personales de pacientes hospitalizados con síntomas de leptospirosis en el Hospital de Pointe à Pitre, Guadalupe, Indias Orientales Francesas, en el período comprendido de 1994 a 2001. De los 897 pacientes investigados, 212 eran casos graves, 607 eran no infectados y 78 eran casos indeterminados. No hubo grupo etario predominante. La transmisión de la leptospirosis seguía el ciclo hidrológico y era mayor en las áreas rurales. La ictericia y sufusión conjuntival fueron significativamente más frecuentes en los casos que en los no casos. Los varones, las profesiones consideradas en riesgo, y el contacto con cerdos o bovinos estuvieron asociados con la infección. Los serogrupos Icterohemorragia, Cynopteri, Australis, Sejroe, Pomona y Ballum fueron serovares presumiblemente responsables de los casos graves

Epidemiologic study of the association between human T-cell lymphotropic virus type 1 and Strongyloides stercoralis infection in female blood donors (Guadeloupe, French West Indies)

This case control study was conducted among female blood donors in Guadeloupe. A total of 85 HTLV-1 positive subjects were matched by age (+/- 5 years) in a 1:3 ratio to 255 HTLV-1 negative controls. The mean age was 48.5 and 48.9 years respectively. Ethnic, environmental and socio-economic risk factors were studied. Four risk factors were found independently associated with HTLV-1 seropositivity: Strongyloides stercoralis antibodies (OR = 3.6, CI 1.8, 7.3), low socio-economic status (OR = 2.0 CI 1.0, 4.0), low educational level (OR = 2.0 CI 1.0, 4.0) and agricultural activity (OR = 2.8 CI 1.4, 5.6). This logistic regression analysis demonstrates the reality of the association between HTLV-1 carriers and Strongyloides stercoralis, and its association with socio-economic and environmental risk factors

Malaria in Guadeloupe (French West Indies) 1991-2000

The only islands in the Caribbean that still have endemic malaria are Haiti and the Dominican Republic. Cases of imported malaria occur on the other islands, particularly Martinique and Guadeloupe, due to the movement of people to and from endemic regions that are geographically and/or culturally close. The re-emergence of transmission cannot be ruled out due to the local persistence of the potential vectors, the anopheles mosquitoes. This retrospective study, over a ten year-period (1991-2000), included all of the cases of malaria confirmed by blood tests at Pointe-à-Pitre University Hospital. This hospital is the main healthcare facility in Guadeloupe. Fifty-nine bouts of malaria occurred in 56 patients. The annual incidence was estimated at 2 to 2.5 cases per 100,000 inhabitants. Plasmodium falciparum largely predominated, accounting for over 80 of cases. The only pernicious case observed resulted in the death of the patient. In all cases the patient had recently travelled to an endemic region, except in one case, caused by P ovale which has never been endemic in the Caribbean. African countries accounted for 43 of cases. No Asian or Pacific strains were identified. In all cases, anti-malarial drugs were not taken, taken incorrectly or were inappropriate. All of the cases of malaria reported in Guadeloupe in the last decade were imported and this region cannot be considered to be at risk of malaria infection. However, long-term epidemiological monitoring is necessary, together with specific entomological monitoring

Trends of AIDS in Guadeloupe (French West Indies): a longitudinal survey from 1998 to 1997

The study objective was to describe morbidity and mortality from HIV infection and the acquired immunodeficiency syndrome (AIDS) in Guadeloupe from 1998 to 1997 and to evaluate survival and prognostic factors. The HIV infected patients database of Guadeloupe included 1771 adult patients up to December 31, 1997. Annual incidence of AIDS defining illnesses were calculated and compared using Poisson regression. Survival analysis with log-rank test and multivariate analysis with Cox's model were performed for patients with AIDS. At the end of December 1997, 599 cases of AIDS (33.8 percent) and 367 deaths (20.7 percent) were reported. For 32.1 percent of the patients, AIDS was diagnosed before inclusion. Incidence of most AIDS-defining events decreased over time, especially after the introduction of protease inhibitor therapy. Before the introduction of protease inhibitors in September 1996, overall median survival after AIDS was 11.8 months (95 percent Confidence Interval (CI), 95 percent CI 10.2 - 14.1.) After this date median survival increased to 17.8 months (95 percent CI 18.6 - 22.5 ) and probability of survival was significantly higher for patients treated with protease inhibitor in combination regimen (mean 19.0 months. Standard deviation (SD) 1.3) compared to those who were not (mean 7.9 months, SD 0.6, p<0.0001). Prognosis factors of death after AIDS were older age (Relative Hazard, RH : 1.17, 95 percent CI 1.07 - 1.28), occurrence of two or more AIDS-defining events at the beginning of the disease (RH: 1.70, 95 percent CI 1.32 - 2.19), and a CD4 cell count less than 50/mm3 (RH: 2.33, 95 percent CI 1.71- 3.17). On the other hand, occurrence of AIDS during follow-up had a better prognosis (RH : 0.68, 95 percent CI 0.52 - 0.89) and protease inhibitor therapy was strongly associated with a longer survival (RH 0.26, 95 percent CI 0.13 - 0.53). We concluded that HIV infection in Guadeloupe was frequently diagnosed at the stage of AIDS. However, survival of patients and trends of major AIDS defining illnesses were more similar to the European pattern than to the Caribbean one, as a consequence of the availability of modern therapy.
