Complete Androgen Insensitivity Syndrome: A Rare Case of Prenatal Diagnosis.

With the widespread uptake of noninvasive prenatal testing (NIPT), a larger cohort of women has access to fetal chromosomal sex, which increases the potential to identify prenatal sex discordance. The prenatal diagnosis of androgen insensitivity syndrome (AIS) is an incidental and rare finding. We wish to present the diagnosis of a prenatal index case after NIPT of cell-free fetal DNA and mismatch between fetal sex and ultrasound phenotype. In this particular case, the molecular analysis of the androgen receptor (AR) gene showed the presence of a pathogenic mutation, not previously reported, consistent with complete androgen insensitivity syndrome. Carrier testing for the mother revealed the presence of the same variant, confirming maternal hemizygous inheritance. Identification of the molecular basis of these genetic conditions enables the preimplantation or prenatal diagnosis in future pregnancies.

Pretendemos apresentar um caso índice de diagnóstico pré-natal por meio de DNA fetal livre e incompatibilidade entre sexo fetal e fenótipo ecográfico.

Value of Bishop score and ultrasound cervical length measurement in the prediction of cesarean delivery.

AIM: The aim of this study was to evaluate the role of Bishop score and cervical length in predicting the outcome of induced labor. MATERIAL AND METHODS: A prospective observational study was performed during a year in women undergoing labor induction. Prior to the procedure, Bishop score was evaluated by transvaginal digital examination and cervical length was measured by transvaginal ultrasound. Demographic data and labor details were recorded. RESULTS: A total of 197 women were analyzed; 166 women had a vaginal delivery (84.3%) and 31 had a cesarean section (15.7%). On univariate analysis, nulliparity, Bishop score >5 and cervical length <30 mm were all associated with cesarean delivery. On multivariate analysis, only nulliparity remained significantly associated with cesarean delivery and the other characteristics did not achieve statistical significance. When women were stratified according to parity, there was a significant association between cesarean delivery and nulliparity, but not multiparity. CONCLUSIONS: Our results suggest that Bishop score and cervical length are good predictors of successful induction of labor, particularly in nulliparous women.

Sociological evaluation of patients with lung cancer--revision study in hospital patients.

Lung cancer was a rare disease until the middle of the XX century, a time when it became one of the most important causes of morbidity and mortality in the actual world. Nowadays, it is esteemed that one million people all over the world die every year due to lung cancer, which means that a life is lost each 30 seconds. The quality of life of this patients decreases inevitably, being frequent hospital readmission due to the lack of conditions to lead a normal and painless life. The aim of this study was to evaluate physical and cognitive incapacity and the social needs of patients with lung cancer in the outpatient department of Hospital de S. João--Porto. Our study includes 68 patients, predominantly married male, with average age of 63, retired, ex-smokers. Moreover, they had high physical dependence degrees and the most frequent social need was the attribution of the "complemento por dependência". In this type of patients, the family has a very important role on which the treatment is concerned, as well as to the level of the personal adjustment of the patient to his disease. Its social workers job to play a mediating role between the patients and their relatives and the several institutions which can give better responses to the needs of this sort of patients.

Screening of plants found in the State of Amazonas, Brazil for activity against Aedes aegypti larvae

Ethanol, methanol and water extracts representing mostly native plant species found in the Amazon region were prepared, respectively, by maceration, continuous liquid-solid extraction and infusion, followed by evaporation and freeze-drying. The freeze-dried extracts were tested for lethality toward Aedes aegypti larvae at test concentrations of 500 mg / mL. In general, methanol extracts exhibited the greatest larvicidal activity. The following 7 methanol extracts of (the parts of) the indicated plant species were the most active, resulting in 100% mortality in A. aegypti larvae: Tapura amazonica Poepp. (root), Piper aduncum L. (leaf and root), P. tuberculatum Jacq. (leaf, fruit and branch). and Simaba polyphylla (Cavalcante) W.W. Thomas (branch).

Extratos aquosos, etanólicos e metanólicos, representando principalmente espécies vegetais nativas encontradas na região Amazônica, foram preparados, respectivamente, por infusão, maceração e extração contínua líquido-sólido, seguida de evaporação e liofilização. Os extratos liofilizados foram testados para atividade contra larvas de Aedes aegypti, na concentração única de 500 mg / mL. Os extratos metanólicos foram, em geral, os que apresentaram maior atividade larvicida. Os seguintes 7 extratos metanólicos das (partes das) espécies vegetais indicadas foram os mais ativos, provocando 100% de mortalidade em larvas de A. aegypti: Tapura amazonica Poepp. (raiz), Piper aduncum L. (folha e raiz), P. tuberculatum Jacq. (folha, fruto e galho) e Simaba polyphylla (Cavalcante) W.W. Thomas (galho).
