OBJETIVO: Foram realizadas medidas antropométricas de recém-nascidos (RN) baianos, para definir medidas condizentes com a realidade desta região. MÉTODO: Estudo tipo corte transversal em bebês de termo e normais com as medidas de perímetro cefálico, distância biauricular, distância anteroposterior, tamanho da fontanela e índice cefálico. RESULTADOS: Foram avaliados 388 bebês, sendo 204 (52,6%) masculinos e 184 (47,4%) femininos. O perímetro cefálico variou entre 31,0 e 38,0 cm, com média de 34,4 ± 1,2. O índice cefálico variou entre 0,75 e 1,06, com média de 0,91 ± 0,05. CONCLUSÃO: As medidas antropométricas são aferidas visando à detecção precoce de anomalias. Possivelmente, estas medidas podem ser influenciadas por fatores raciais; no entanto, as medidas realizadas no Brasil em geral seguem valores de autores estrangeiros. Assim, o estudo mostra dados de uma região nordestina e salienta a importância da realização de estudos multicêntricos.

    • "Regarding gestational age, one study found that newborns of mothers with DM I were born at lower gestational ages than those of mothers with GDM (21). In a similar study, the 1- and 5-minute Apgar scores of infants from women with DM I, DM II and GDM were 5±2 and 9±0.5, 8±1.5 and 10±0.5, and 9±1.5 and 10±0.5, respectively (22). In our study, there was no statistically significant relationship between Apgar scores and the type of maternal DM. "

    ABSTRACT: The current study sought to identify macroscopic placental changes associated with clinical conditions in women with or without diabetes and their newborns. The study population consisted of 62 pregnant women clinically diagnosed with diabetes and 62 healthy women (control group). Among the subjects with diabetes, 43 women (69.3%) were diagnosed with gestational diabetes mellitus, 15 had diabetes mellitus I (24.2%), and four had diabetes mellitus II (6.5%). The mean age of the women studied was 28.5 ± 5.71 years, and the mean gestational age of the diabetic women was 38.51 weeks. Of the 62 placentas from diabetic pregnancies, 49 (79%) maternal surfaces and 59 (95.2%) fetal surfaces showed abnormalities, including calcium and fibrin deposits, placental infarction, hematoma, and fibrosis. A statistical association was found between newborn gender and fetal and maternal placental changes (p = 0.002). The mean weight of the newborns studied was 3,287 ± 563 g for women with diabetes mellitus, 3,205 ± 544 g for those with gestational diabetes mellitus, 3,563 ± 696 g forthose with diabetes mellitus II, and 3,095 ± 451 g forthose with diabetes mellitus I. Infarction, hematoma, calcification, and fibrin were found on the maternal and fetal placental surfaces in women with diabetes. Women with gestational diabetes and post-term infants had more calcium deposits on the maternal placental surface as compared to those with type I and type II diabetes.

    ABSTRACT: Cool cap is a device used in newborns with perinatal asphyxia. Several researches have pointed that localized hypothermia can decrease the metabolism of brain, which would reduce the sequelae on the brain due to the absence of oxygen. The system for cooling of conventional cool caps is based on the recirculation of a cold fluid around the head of the newborn. The main disadvantage of this system is the size of device, which is large because of the reservoir for the fluid and the mechanical devices for the cooling of fluid. In this work, it is proposed to design a cool cap using Peltier effect in the cooling system. The use of plates with Peltier effect could decrease significantly the size of apparatus. For the correct design, a thermodynamic model of the skull of newborns was developed in order to determine the thermal load of the system. In this model, the temperature of brain should be around 34.5 º C for a mild localized hypothermia. The model of Yablonskiy, which is based on adult head, was adapted in this work for the case of newborns. The mechanical structure of cool cap was designed using the average values of the dimensions of heads of newborns. Also, the average geometry of heads of newborns was evaluated and considered in the mechanical design. A proper control of the plates of Peltier was also developed using microcontrollers and thermal sensors (LM35). This paper presents the method to evaluate the heat transfer of the cool cap to the brain and the firsts impressions with the prototype of cool cap.
