RESUMO

OBJECTIVE: To determine the correlation of ultrasonographic estimation of fetal weight and actual birthweight and the impact of the level of resident s training on the results. METHODS: This was a prospective study of 90 women with term pregnancies. Ultrasound estimated fetal weight (EFW) was calculated by a pre-programmed Hadlock formula. Days from ultrasound to delivery were less than seven. The EFW was compared to the actual birthweight at delivery. The year of training of the resident that performed the ultrasound was recorded. Exclusion criteria included diabetes mellitus and known fetal anomalies. RESULTS: Mean age was 28 years, parity was 0 to 4 and mean gestational age was 38 weeks. There was an average over-estimation of 64.8 grams. The difference between mean EFW and mean birthweight was not significant (p = 0.067). The difference between mean EFW and mean birthweight when calculated according to year of residency was not significant, p = 0.075 and 0.402for junior and senior residents, respectively. CONCLUSION: There is good correlation between residents' ultrasonographic estimation of fetal weight and actual birthweight at the UHWI. There was no significant difference in correlation between senior and junior residents. Developments in computer technology might contribute to decrease in the learning curve.

OBJETIVO: Determinar la correlación de la estimación ultrasonográfica del peso fetal y el peso real al nacer, y el impacto del nivel de formación del residente en los resultados. MÉTODOS: Se trató de un estudio prospectivo de 90 mujeres con embarazos a término. El peso fetal estimado (PFE) por ultrasonido fue calculado mediante una fórmula de Hadlock preprogramada. Los días transcurridos desde el ultrasonido hasta el parto fueron menos de siete. Se comparó el PFE con el peso real en el parto. Se registró el año de formación del residente que realizó el ultrasonido. Los criterios de exclusión criterios incluyeron diabetes mellitus y anomalías fetales conocidas. RESULTADOS: La edad promedio fue 28 años; la paridad fue de 0 a 4; la edad gestacional fue de 38 semanas. Hubo una sobreestimación promedio de 64.8 gramos. La diferencia entre el PFE promedio y el peso promedio al nacer no fue significativa (p = 0.067). La diferencia entre el PFE promedio y el peso promedio al nacer calculada según el año de residencia no fue significativa, siendo p = 0.075 y 0.402 para médicos en la primera y última etapa de su residencia, respectivamente. CONCLUSIÓN: Existe una buena correlación entre la estimación ultrasonográfica del peso fetal, realizada por los residentes, y el peso real al nacer en el HUWI. No hubo ninguna diferencia significativa en la correlación entre los residentes en sus primeras y últimas etapas. Los desarrollos en la tecnología informática pueden contribuir a la disminución de la curva de aprendizaje.

RESUMO

OBJECTIVE: To determine the correlation of ultrasonographic estimation of fetal weight and actual birthweight and the impact of the level of resident's training on the results. METHODS: A prospective study of 90 women with term pregnancies. Ultrasound estimated fetal weight (EFW) was calculated by a preprogrammed Hadlock formula. Days from ultrasound to delivery were less than seven. The EFW was compared to the actual birthweight at delivery. The year of training of the resident that performed the ultrasound was recorded. Exclusion criteria included Diabetes mellitus and known fetal anomalies. RESULTS: Mean age was 28 years, parity zero to four, mean gestational age 38 weeks. There was an average over-estimation of 64.8 grams. The difference between mean EFW and mean BWT was not significant (p = 0.067). The difference between mean EFW and mean BWT when calculated according to year of residency was not significant, p = 0.075 and 0.402 for junior and senior residents, respectively. CONCLUSION: There is good correlation between resident's ultrasonographic estimation of fetal weight and actual birthweight at the UHWI. There was no significant difference in correlation between senior and junior residents. Development in computer technology might contribute to decrease in the learning curve.

RESUMO

OBJECTIVE: Pumpkin seed oil is rich in phytoestrogens and animal studies suggest that there is some benefit to supplementation in low estrogen conditions. This study is the first to evaluate the benefit of pumpkin seed oil in postmenopausal women. METHODS: This pilot study was randomized, double-blinded and placebo-controlled. Study participants included 35 women who had undergone natural menopause or had iatrogenically entered the climacteric due to surgery for benign pathology. Wheat germ oil (placebo; n = 14) and pumpkin seed oil (n = 21) were administered to eligible participants over a 12-week period at a dose of 2 g per day. Serum lipids, fasting plasma glucose and blood pressure were measured and an 18-point questionnaire regarding menopausal symptoms was administered; the atherogenic index was also calculated. Differences between groups, as well as before and after the period of supplementation, were evaluated with Student's t-test, Wilcoxon matched-pair signed-ranked test and Mann-Whitney test, as appropriate (Stata version 10.1). RESULTS: Women receiving pumpkin seed oil showed a significant increase in high density lipoprotein cholesterol concentrations (0.92 ± 0.23 mmol/l vs. 1.07 ± 0.27 mmol/l; p = 0.029) and decrease in diastolic blood pressure (81.1 ± 7.94 mmHg vs. 75.67 ± 11.93 mmHg; p < 0.046). There was also a significant improvement in the menopausal symptom scores (18.1 ± 9.0 vs. 13.2 ± 6.7; p < 0.030), with a decrease in severity of hot flushes, less headaches and less joint pains being the main contributors. Women in the group receiving wheat germ oil reported being more depressed and having more unloved feeling. CONCLUSION: This pilot study showed pumpkin seed oil had some benefits for postmenopausal women and provided strong evidence to support further studies.

RESUMO

The mutation in the hypoxanthine-guanine phosphoribosyltransferase (HPRT) gene has been determined in two brothers affected with Lesch-Nyhan syndrome. Female members of the family who are at risk for being heterozygous carriers of the HPRT mutation were also studied to determine whether they carry the mutation. DNA sequencing revealed that the boys' mother is heterozygous for the mutation in her somatic cells, but that three maternal aunts are not heterozygous. Such carrier information is important for the future pregnancy plans of at-risk females. The mutation, an A-->T transversion at cDNA base 590 (590A-->T), results in an amino acid change of glutamic acid to valine at codon 197, and has not been reported previously in a Lesch-Nyhan syndrome male. This mutation is designated HPRTBrasil.
