Minor sperm abnormalities in young male post-pubertal patients with juvenile dermatomyositis

The objective of the present study was to identify sperm abnormalities in young male patients with juvenile dermatomyositis (JDM). In 2005, 18 male JDM patients, diagnosed according to the criteria of Bohan and Peter, were followed at the Pediatric Rheumatology Unit and Rheumatology Division, of our Institution. Of the 18 males, 11 were pre-pubertal and 7 were post-pubertal. Two of 7 post-pubertal JDM male patients were excluded: one for orchidopexy for cryptorchidism and the other for testicular ectopia in the left testis. The remaining 5 post-pubertal JDM patients were prospectively evaluated on the basis of two semen analyses, according to the World Health Organization (WHO), urologic evaluation, testicular Doppler ultrasound hormone profile. The data of the JDM patients were compared with those of 5 age-matched healthy controls. The median age 18, was similar in JDM patients and controls. All JDM patients had teratozoospermia (abnormal sperm morphology), as did 4 (80%) of the controls. One of JDM patients had previous oligoasthenoteratozoospermia treated with intravenous cyclophosphamide with normalization of the number and concentration of the sperm after 5 years. All sperm parameters (sperm concentration, total sperm count and total motile sperm count by WHO, and sperm morphology by Kruger strict criteria), testicular volumes by Prader orchidometer and ultrasound, and hormones were similar in JDM patients compared with controls. The frequency of anti-sperm antibodies was similar in both groups. All JDM patients had minor sperm abnormalities in the head, midpiece, and/or tail of spermatozoids. Serial semen analyses in larger study populations are necessary to identify the extent and duration of sperm abnormalities in male patients with idiopathic inflammatory myopathies.FAPESPCNP

The Study Of Cardiovascular Risk In Adolescents - Erica: Rationale, Design And Sample Characteristics Of A National Survey Examining Cardiovascular Risk Factor Profile In Brazilian Adolescents

Background: The Study of Cardiovascular Risk in Adolescents (Portuguese acronym, "ERICA") is a multicenter, school-based country-wide cross-sectional study funded by the Brazilian Ministry of Health, which aims at estimating the prevalence of cardiovascular risk factors, including those included in the definition of the metabolic syndrome, in a random sample of adolescents aged 12 to 17 years in Brazilian cities with more than 100,000 inhabitants. Approximately 85,000 students were assessed in public and private schools. Brazil is a continental country with a heterogeneous population of 190 million living in its five main geographic regions (North, Northeast, Midwest, South and Southeast). ERICA is a pioneering study that will assess the prevalence rates of cardiovascular risk factors in Brazilian adolescents using a sample with national and regional representativeness. This paper describes the rationale, design and procedures of ERICA. Methods/Design: Participants answered a self-administered questionnaire using an electronic device, in order to obtain information on demographic and lifestyle characteristics, including physical activity, smoking, alcohol intake, sleeping hours, common mental disorders and reproductive and oral health. Dietary intake was assessed using a 24-hour dietary recall. Anthropometric measures (weight, height and waist circumference) and blood pressure were also be measured. Blood was collected from a subsample of approximately 44,000 adolescents for measurements of fasting glucose, total cholesterol, HDL-cholesterol, LDL-cholesterol, triglycerides, glycated hemoglobin and fasting insulin. Discussion: The study findings will be instrumental to the development of public policies aiming at the prevention of obesity, atherosclerotic diseases and diabetes in an adolescent population.151Schmidt, M.I., Duncan, B.B., Silva, G.A., Menezes, A.M., Monteiro, C.A., Barreto, S.M., Chronic non-communicable diseases in brazil: Burden and current challenges (2011) Lancet, 377 (9781), pp. 1949-1961Juonala, M., Viikari, J.S., Kahonen, M., Taittonen, L., Laitinen, T., Hutri-Kahonen, N., Life-time risk factors and progression of carotid atherosclerosis in young adults: The cardiovascular risk in young finns study (2010) Eur Heart J., 31 (14), pp. 1745-1751WHO, Obesity - Preventing and managing the global epidemic (2004) Geneva: Report of a WHO Consultation on Obesity, , World Health OrganizationJuonala, M., Magnussen, C.G., Berenson, G.S., Venn, A., Burns, T.L., Sabin, M.A., Childhood adiposity, adult adiposity, and cardiovascular risk factors (2011) N Engl J Med., 365 (20), pp. 1876-1885Williams, D.E., Cadwell, B.L., Cheng, Y.J., Cowie, C.C., Gregg, E.W., Geiss, L.S., Prevalence of impaired fasting glucose and its relationship with cardiovascular disease risk factors in us adolescents, 1999-2000 (2005) Pediatrics, 116 (5), pp. 1122-1126IBGE, (2010) Antropometria E Estado Nutricional de Crianças, Adolescentes E Adultos No Brasil2008-2009, p. 130. , Pesquisa de Orçamentos Familiares (POF).
