- Choque tóxico por streptococcus B hemoliticus do grupo APublication . Pontes, T; Antunes, HIn the last years has been observed an increased incidence of invasive group A beta-hemolytic streptococcal infections, including the toxic shock syndrome. The most common portal of entry is the skin and mucous membranes. The toxic shock syndrome can occurred as a rare complication of pharyngitis. The association between varicella and the use of nonsteroidal antiinflammatory drugs with necrotizing fasciitis by Streptococcus pyogenes has been discussed without reach at consensus, but some authors disapproved the use of nonsteroidal antiinflammatory drugs in this viral infection. The authors reported the clinical case of a 12 year old adolescent, that 15 days after the diagnosis of mononucleosis infectious confirmed by serology and treated with ibuprofen, was internment by streptococcal toxic shock syndrome with rhabdomyolysis, hepatitis, cellulitis of the leg, arthritis of the knee and pleural effusion. Therapeutics was made with penicillin G and clindamycin. We present this case for the severity of the clinical situation and for the questions that rise.

- Taxa de cobertura vacinal com imunização para o vírus da hepatite BPublication . Antunes, H; Macedo, M; Estrada, AThe hepatitis B virus is an important cause of morbidity and mortality in humans, thus making it a serious public health issue. The purpose of this study was to determine the hepatitis B virus vaccination rate with immunization, the risk of this population group becoming infected before vaccination and the prevalence of hepatitis B virus infection. The study involved randomly analyzing the serum of 311 adolescents of both sexes aged 14 from a total population of 536 adolescents attending schools in Braga, Portugal. A questionnaire was administered to the adolescents and asked them if they had received the Hepatitis B vaccine, how many doses they received, if they had a history of acute hepatitis, drug abuse, whether or not they had had sexual intercourse and if so, if they had used protection. The determination of the hepatitis B surface antigen (HbsAg), the antibody to HbsAg and the antibody to hepatitis B core antigen was carried out using the chemoluminiscence method. The vaccination rate with immunization was 85.8 %, [95% CI 81.9-89.7%]. The prevalence of hepatitis B virus infection was 0.6%, [95% CI 0-1.5%]. Conclusions: The prevalence of hepatitis B virus infection was low in this adolescent population of Braga. The vaccination rate with immunization is satisfactory, but does not reach 100%, which means that the risk of transmission is still present in this age group.
- Congenitally corrected transposition of the great arteries and aortic coarctation--an uncommon associationPublication . Brandão, A; Magalhães, S; Correia, ACongenitally corrected transposition of the great arteries, L-TGA, is a rare abnormality accounting for less than 0.5% of clinically apparent congenital heart disease. Age at time of diagnosis and survival rate are variable and depend mostly on associated anomalies. The authors present a clinical case of a twenty-four-year-old woman in whom, in a routine echocardiogram, congenitally corrected transposition of the great arteries and aortic coarctation were diagnosed, an unusual association. They describe the results of complementary exams (echocardiography, chest X-ray, electrocardiogram and cardiac angiography) that they believe to be useful for the correct diagnosis of this clinical situation. Additionally, the authors make a brief review of the literature relevant to the case.
- Quisto da Vesicula Seminal Sintomático – Diagnóstico e Implicações TerapeuticasPublication . Cabral-Ribeiro, J; Sousa, L; Mendes, M; Ribeiro dos Santos, AOs quistos da vesícula seminal são uma patologia relativamente frequente. São quistos congénitos ou adquiridos, na maioria assintomáticos e diagnosticados como achados imagiológicos. Ocasionalmente, podem dar origem a complicações infecciosas, manifestando-se com sintomatologia semelhante a prostatite, dar sintomas miccionais (irritativos ou obstrutivos), dor pélvica ou causar infertilidade. Relatamos o caso clínico de doente com quisto da vesícula seminal complicado de abcesso a que se associou um quisto vesical com tecido seminal ectópico. O doente foi tratado com antibioterapia sistémica, drenagem do abcesso por via transrectal e ressecção transuretral da lesão vesical. Realizamos uma breve revisão sobre a patologia quística das vesículas seminais.
- Secretory breast carcinoma--case report and review of the medical literature.Publication . Costa, NM; Rodrigues, H; Pereira, H; Pardal, F; Matos, ESecretory breast carcinoma (SBC) is a rare type of invasive breast cancer. Since little is known about the biology of this rare tumour, it is useful to report every such case, in order to make as much information as possible available in the medical literature. We present the case of an 18-year-old woman with a SBC treated by mastectomy (Madden) and axillary node dissection (stage pT3N1M0) followed by chemotherapy (FEC regimen) and radiotherapy. The patient has meanwhile completed 4 years of follow-up with no evidence of recurrence. The authors review the literature and summarize relevant findings concerning definition, pathology, clinical picture, treatment, and follow-up.

- Prevalência do vírus da hepatite A: primeiros resultados de baixa endemicidade em PortugalPublication . Antunes, H; Macedo, M; Estrada, AThe prevalence of the hepatitis A virus in a population determines the degree of morbidity associated with this illness, that is, the higher the morbidity, the lower the prevalence. This study aims to obtain the prevalence of total antibody to the hepatitis A virus in children, 5 and 8 years of age, and in adolescents, 14 years of age. The study was based on two samples: the serum of 64 healthy five-year-olds and 76 healthy eight-year-olds living in the proximity of the São Marcos Hospital in Braga and the serum of 311 adolescents, aged 14, from a total population of 536 adolescents attending schools in Braga, North of Portugal. The samples were collected in 1999 for the adolescent group, in 2000 and 2001 for the group of the five-year-olds and in 2002 and 2003 for the group of the eight-year-olds. None of the persons involved had been vaccinated with the hepatitis A virus vaccine. The Enzyme Linked Fluorescent Assay method was used to measure the serum total antibody to the hepatitis A virus. The prevalence of total antibody to the hepatitis A virus was 1.6% at 5 years of age, [95% confidence intervals (CI), 0-4.7%]; 3.9% at 8 years of age, [95% CI, 0-8,4%]; and 32.5% at 14 years of age +/- 6 months, [95% CI, 27.3-37.7%]. The prevalence of total antibody to the hepatitis A virus in this population revealed lower natural immunity. The results obtained for the five and eight-year-olds were the first Portuguese results of low endemicity to the hepatitis A virus.
