ABSTRACT
OBJETIVO: apresentar o quadro clínico das pacientes com metaplasia óssea e avaliar os fatores de risco, as mudanças dos sinais e sintomas após a retirada do fragmento ósseo. MÉTODOS: foi realizado um estudo transversal com 16 pacientes diagnosticadas com fragmentos ósseos na cavidade uterina no período de julho de 2006 a janeiro de 2009. O critério de inclusão foi o achado de fragmento ósseo retirado da cavidade uterina. Todas as pacientes tiveram confirmação histológica de presença de tecido ósseo na cavidade endometrial. Obtivemos os dados de todas as pacientes antes e depois da retirada por meio de um questionário para avaliar o efeito da retirada sobre a sintomatologia das pacientes, além da pesquisa de possíveis fatores relacionados ao aparecimento da doença. RESULTADOS: metade das pacientes (8/16) tinha sintomas hemorrágicos e um terço (6/16) apresentava infertilidade. A retirada dos fragmentos foi efetiva na melhora das queixas, havendo desaparecimento dos sintomas em todos os casos de menorragia e dor pélvica. CONCLUSÃO: A retirada do fragmento ósseo pode restaurar a fertilidade em pacientes selecionadas e que tenham como causa a metaplasia óssea, além de ser bastante efetiva em proporcionar melhora nos casos que cursam com dor pélvica e menorragia.
PURPOSE: to describe the clinical signs and symptoms of patients with bone metaplasia and to assess the risk factors for changes in these symptoms after removal of the bone fragment. METHODS: a cross-sectional study was conducted on 16 patients with a diagnosis of bone fragments in the uterine cavity during the period comprising July 2006 to January 2009. The inclusion criterion was the detection of a bone fragment removed from the uterine cavity. The presence of bone tissue in the endometrial cavity was histologically confirmed in all patients. The data of all patients were obtained before and after removal by means of a questionnaire for the evaluation of the effect of removal on the symptoms and for the search of possible factors related to the onset of the disease. RESULTS: half the patients (8/16) had hemorrhagic symptoms and one third (6/16) were infertile. Removal of the fragments was quite effective in improving the complaints, with the disappearance of symptoms in all cases of hemorrhage and of pelvic pain. CONCLUSION: removal of bone fragments can restore the fertility of selected patients whose infertility is caused by bone metaplasia and is quite effective in leading to improvement in patients with pelvic pain and menorrhage.

OBJETIVO: Este estudo avaliou a contribuição de seis polimorfismos genéticos presentes em genes do sistema renina-angiotensina-aldosterona (SRAA) e fatores de risco clínicos para o desenvolvimento da hipertensão arterial essencial em um município da região Amazônica. MÉTODOS: Oitenta e dois indivíduos hipertensos e setenta e oito indivíduos normotensos foram genotipados quanto à presença de polimorfismos REN-G1051A (renina), AGT-M235T (angiotensinogênio), ECA-Alu I/D (enzima conversora de angiotensina I), AGTR1-A1166C (receptor tipo 1 da angiotensina II) e CYP11B2-C344T (aldosterona sintetase) pela técnica de reação em cadeia da polimerase (PCR), com análise de restrição quando necessário. A influência de polimorfismos genéticos e fatores de risco clínicos na variação da pressão arterial foi avaliada por meio de regressão linear stepwise. RESULTADOS: Relatamos a co-ocorrência de fatores de risco clínicos e polimorfismo do gene da enzima conversora de angiotensina (ECA) na população de um município da região amazônica. Nossos resultados mostram que a elevação da pressão arterial sistólica é favorecida pelo alelo D do polimorfismo de inserção/deleção do gene da ECA e pelo aumento da idade, enquanto consumo de bebida alcoólica e envelhecimento estão associados ao aumento da pressão arterial diastólica (PAD). CONCLUSÃO: Esses achados indicam que os moradores de Santa Isabel do Rio Negro que possuem o alelo D da ECA ou têm o hábito de beber apresentam valores mais elevados de PAS e PAD, respectivamente, com o passar dos anos.
OBJECTIVE: In the present study, we evaluated the contribution of six genetic polymorphisms of the Renin-Angiotensis-Aldosterone system (RAAS) and clinical risk factors in the development of essential hypertension in a Brazilian rural population in the Amazon region. METHODS: Eighty-two hypertensive patients and seventy-eight normotensive individuals were evaluated. Genotyping for renin (REN G1051A), angiotensinogen (AGT) M235T, insertion/deletion of angiotensin-converting enzyme (ACE I/D), angiotensin II type 1 receptor (AGTR1) A1166C and aldosterone synthase (CYP11B2) C344T polymorphisms were performed using polymerase chain reaction, with further restriction analysis when required. The influence of genetic polymorphisms and clinical risk factors on blood pressure variation was assessed by stepwise linear regression. RESULTS: We report the co-occurrence of clinical risk factors and angiotensin-converting enzyme (ACE) gene polymorphism in a Brazilian rural population in the Amazon region. Our results indicate that increase of systolic blood pressure (SBP) is favored by ACE I/D- D allele and advanced age, while alcohol consumption and aging are associated with high diastolic blood pressure (DBP). CONCLUSION: These findings suggest that in the Santa Isabel do Rio Negro population, the residents that carry ACE-D allele or have an alcohol consumption habit present higher values of SBP and DBP, respectively, with the passing of years.

Myotonic dystrophy (DM) is a neuromuscular disorder caused by the expansion of the cytosine-thymine-guanine (CTG) repeat of the myotonic dystrophy protein kinase gene (DMPK). This repeat is highly polymorphic in healthy individuals [(CTG)5-37], and it has been proposed that expanded CTG alleles originated from larger sized normal alleles [(CTG)19-37]. According to this hypothesis, a positive correlation should be expected between the frequency of these large-sized normal alleles and the prevalence of the disorder in a population. We determined the distribution of CTG alleles of the DMPK gene in 156 healthy Brazilians from Rio de Janeiro city. Our analyses of 312 chromosomes detected 20 different alleles ranging in size from 5 to 27 CTG repeats, with 24 alleles having more than 18 repeats (7.69 percent). This frequency of (CTG)3(19) alleles observed in our population suggests that the prevalence of DM in Rio de Janeiro should not be different from the prevalence in European populations.

Fixed bin frequencies for the VNTR loci D2S44, D4S139, D5S110, and D8S358 were determined in a Minas Gerais population sample. The data were generated by RFLP analysis of HaeIII-digested genomic DNA and chemiluminescent detection. The four VNTR loci have met Hardy-Weinberg equilibrium, and there was no association of alleles among VNTR loci. The frequency data can be used in forensic analyses and paternity tests to estimate the frequency of a DNA profile in the general Brazilian population
