RESUMEN
OBJECTIVES: Nicaraguan sugarcane workers, particularly cane cutters, have an elevated prevalence of chronic kidney disease of unknown origin, also referred to as Mesoamerican nephropathy (MeN). The pathogenesis of MeN may include recurrent heat stress, crystalluria, and muscle injury with subsequent kidney injury. Yet, studies examining the frequency of such events in long-term, longitudinal studies are limited. METHODS: Using employment and medical data for male workers at a Nicaraguan sugarcane company, we classified months of active work as either work as a cane cutter or other sugarcane job and determined occurrence of dysuria, heat events and muscle events. Work months and events occurred January 1997 to June 2010. Associations between cane cutting and each outcome were analyzed using logistic regression based on generalized estimating equations for repeated events, controlling for age. RESULTS: Among 242 workers with 7257 active work months, 19.5% of person-months were as a cane cutter. There were 160, 21, and 16 episodes of dysuria, heat events, and muscle events, respectively. Compared with work months in other jobs, cane cutting was associated with an elevated odds of dysuria [odds ratio 2.40 (95% confidence interval 1.56-3.68)]. The number of heat and muscle events by cane cutter and other job were limited. CONCLUSIONS: Working as a cane cutter compared with other jobs in the sugarcane industry was associated with increased dysuria, supporting the hypothesis that cane cutters are at increased risk of events suspected of inducing or presaging clinically evident kidney injury.

OBJECTIVES: Our study evaluates the reliability and validity of a Chinese version of the Urinary Tract Infection Symptom Assessment questionnaire (UTISA). MATERIAL AND METHODS: Our study enrolled women who were diagnosed with uncomplicated urinary tract infection (uUTI) at clinics. The Chinese version of UTISA was completed upon first visit to the clinic for uUTI and at 1-week follow-up. We enrolled 124 age-matched women without uUTI from the community as the control group. The UTISA consists of 14 items (seven symptom items and seven related to quality of life), with each item scoring 0 to 3. The internal consistency was assessed with Chronbach's alpha test. Factor analysis was used to classify symptoms into latent factors. The predictive validity was analyzed by using logistic regression and Receiver Operating Characteristic (ROC) curve analysis. RESULTS: Mean total symptom scores of the UTISA in the 169 cases and 124 controls were 8.9 ± 4.6 and 1.4 ± 2.4, respectively (p < 0.01). The alpha coefficient was 0.77, showing a homogeneous composition of symptoms. At a cut-off value of greater than 3, the UTISA symptom score had good predictive value for uUTI (sensitivity of 87.0%, and specificity of 93.1%). Factor analysis revealed two latent variables: 1) lower urinary tract symptoms and 2) physical symptoms. Among the seven items, we found that urinary frequency (OR = 2.6), dysuria (OR = 5.0), sense of incomplete emptying (OR=2.0), and hematuria (OR=7.6) were significant predictors for uUTI. CONCLUSIONS: The Chinese version of UTISA is reliable to predict uncomplicated UTI in women with an optimal cut-off point at > 3.

A pesar de los avances tecnológicos, la historia clínica y el examen físico continúan y continuarán siendo la base de un buen enfoque y aproximación diagnóstica correcta, por ésto, la semiología sigue siendo un área muy importante en la medicina. En ésta revisión se plantea una guía sistemática e integral para la evaluación del sistema nefro-urológico en el niño desde las herramienta básicas y fundamentales como la historia clínica, el examen físico con sus componentessemiológicos en lo normal y lo patológico, integrando además los métodos diagnósticos de laboratorio e imagen disponibles en la actualidad, para lograr un buen enfoque y aproximación diagnóstica en niños con enfermedad renal.
Despite technological advances, medical history and physical examination remain the foundation of a good approach and correct diagnosis; semiology remains a very important area in medicine. In this review a systematic and comprehensive guide for the evaluation of nephron urological system in children is presented, with emphasis in medical history, physical examination and semiotic aspects, in normal and pathological conditions; additionally laboratory and imaging studies available to achieve a good diagnostic approach in children with renal disease are presented.

OBJECTIVES: To describe the frequency of urologic manifestations in human T-cell lymphotropic virus type I (HTLV-I) seropositive individuals from Salvador and other cities in Bahia, Brazil, with or without clinical HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP). METHODS: A total of 218 HTLV-I seropositive subjects referred from blood banks or neurologic clinics were admitted to the HTLV-I multidisciplinary outpatient clinic from January 2001 to April 2004. They were assessed using a standardized questionnaire to determine urinary complaints and quality of life. Neurologic impairment was established using the Expanded Disability Status Scale (EDSS). HAM/TSP was considered as an EDSS score of 2 or greater. RESULTS: Nocturia (35.8%) was the most frequent finding, followed by incontinence (29.8%), urgency (25.2%), frequency (22.0%), and dysuria (15.6%). Differences were found between individuals with an EDSS score of 0 and those with an EDSS score greater than 0 but less than 2 regarding frequency, nocturia, urgency, urinary loss of any degree, and quality of life. Dysuria and great or total urinary loss were more frequent among those with severe HAM/TSP (EDSS score greater than 6). CONCLUSIONS: Even HTLV-I subjects considered not to have HAM/TSP may have prominent urinary findings already present. Urologic manifestations, including nocturia and urinary loss, might be early manifestations of neurologic disease in those with HTLV-I.

OBJECTIVE: To determine prevalences and predictors of sexually transmitted and reproductive tract infections among men and women seeking care at pharmacies. METHODS: Men and women with urethral discharge or dysuria and vaginal discharge were enrolled at 12 central and 52 smaller pharmacies in Lima, Peru. All participants answered a questionnaire. Men provided urine for polymerase chain reaction (PCR) testing for Neisseria gonorrhoeae and Chlamydia trachomatis, and for leucocyte esterase testing. Women provided self-obtained vaginal swabs for PCR testing for N gonorrhoeae and C trachomatis, Trichomonas vaginalis culture and bacterial vaginosis and Candida. RESULTS: Among 106 symptomatic men, N gonorrhoeae and C trachomatis were detected in 34% and were associated with urethral discharge compared with dysuria only (odds ratio (OR) 4.3, p = 0.003), positive urine leucocyte esterase testing (OR 7.4, p = 0.009), less education (OR 5.5, p = 0.03), and with symptoms for <5 days (OR 2.5, p = 0.03). Among 121 symptomatic women, 39% had bacterial vaginosis or T vaginalis, and 7.7% had candidiasis. N gonorrhoeae and C trachomatis were detected in 12.4% of the women. Overall, 48.8% had one or more of these infections. No factors were associated with vaginal infection, and only symptoms of vaginal discharge for <5 days were associated with N gonorrhoeae and C trachomatis (OR 4.0, p = 0.02). The main reason reported for seeking advice at pharmacies by both men and women was trust in pharmacy workers. CONCLUSIONS: Among men and women presenting to pharmacies with urethral and vaginal symptoms, rates of urethral and vaginal infections were comparable to those found in other clinical settings. Pharmacies can contribute to the care and prevention of sexually transmitted infection in developing countries.
