PURPOSE: to assess the morphological and morphometric alterations in the uterine cervix of pregnant albino rats determined by local hyaluronidase administration. METHODS: ten rats with a positive pregnancy test were randomly distributed into two equal groups. The control group consisted of rats that received a single dose of 1 mL distilled water in the uterine cervix, on gestational day 18, under anesthesia. The experimental group consisted of rats that received 0.02 mL hyaluronidase, diluted in 0.98 ml distilled water (total = 1 mL), in the same conditions as those of the control group. On day 20, the rats were anesthetized and submitted to dissection. The uterine cervix was prepared for morphological and morphometric study at light microscopy (hematoxylin and eosin, and Masson trichrome). RESULTS: in the experimental group, greater thinning of the superficial mucified epithelium was observed, with lamina propria rich in blood vessels and eosinophils. Diversely, the control group showed a large concentration of collagen fibers. The histometric analysis in the experimental group was characterized by a smaller number of collagen fibers (mean = 248 versus 552 of control; SD = 49.7 versus 31.1 of control). The parametric method (Student's t test) showed a significant difference between groups (p<0.0001). CONCLUSION: the local use of hyaluronidase in the cervix of pregnant rats determined predominance of loose connective tissue and a smaller concentration of collagen fibers.

PURPOSE: to investigate the association between gene polymorphism of the progesterone receptor (PROGINS) and the risk of premature birth. METHODS: In this case-control study, 57 women with previous premature delivery (Case Group) and 57 patients with delivery at term in the current pregnancy and no history of preterm delivery (Control Group) were selected. A 10 mL amount of peripheral blood was collected by venipuncture and genomic DNA was extracted followed by the polymerase chain reaction (PCR) under specific conditions for this polymorphism and 2% agarose gel electrophoresis. The bands were visualized with an ultraviolet light transilluminator. Genotype and allele PROGINS frequencies were compared between the two groups by the χ2 test, with the level of significance set at value p<0.05. The Odds Ratio (OR) was also used, with 95% confidence intervals. RESULTS: PROGINS genotypic frequencies were 75.4% T1/T1, 22.8% T1/T2 and 1.8% T2/T2 in the Group with Preterm Delivery and 80.7% T1/T1, 19.3% T1/T2 and 0% T2/T2 in the term Delivery Group. There were no differences between groups when genotype and allele frequencies were analyzed: p=0.4 (OR=0.7) and p=0.4 (OR=0.7). CONCLUSIONS: the present study suggests that the presence of PROGINS polymorphism in our population does not constitute a risk factor for premature birth.

PURPOSE: to evaluate the performance of the combined first trimester screening for chromosomal abnormalities in a group of the Brazilian population. METHODS: a retrospective study including pregnant women with single fetuses referred to a fetal medicine center to perform the first trimester screening that combines maternal age, nuchal translucency measurement and two maternal serum biochemical markers: free B-hCG and PAPP-A. To evaluate the performance of the test, the detection rate, specificity, negative and positive predicted values and false-positive rates were calculated, considering as high risk the cut-off value above 1 in 300. RESULTS: we studied 456 patients submitted to the test. Advanced maternal age above 35 years was observed in 36.2% of cases. The incidence of chromosomal abnormalities in the study population was 2.2%. Twenty-one patients (4.6%) presented a high risk (above 1:300) by the combined test. Using this cut-off level, the detection rate of the test was 70% for all chromosomal abnormalities and 83.3% for trisomy 21, for a false-positive rate of 3.1%. CONCLUSIONS: the combined first trimester screening was effective to detect chromosomal abnormalities, mainly for trisomy 21, with low false-positive rates. The combined test contributed to decreasing the indication of an invasive test if we compare to maternal age alone as a risk factor.

PURPOSE: to determine whether prenatal sonographic findings and uterine contractions can predict neonatal motor outcome in fetuses with open spina bifida. METHODS: we evaluated retrospectively 53 fetuses with open spina bifida from 1993 to 2001. These fetuses were born and followed-up at the fetal medicine units of the Hospital São Paulo ("Universidade Federal de São Paulo") and the "Hospital Santa Joana". The influence of the alterations observed through ultrasound scan on neonatal muscular strength (macrocrania, microcrania, level of the spinal column opening, clubfoot and type of fetus position) was evaluated. The influence of uterine contractions on neonatal motor outcome was also evaluated. All deliveries were made through cesarian section. c² and Fisher tests were used for categorical comparisons. A p<0.05 was considered significant. RESULTS: Fifty-three cases of isolated open spina bifida were studied. Alterations of the cranial circumference size and the level of the lesion did not interfere in the neonatal motor perfomance. However, clubfoot and breech position showed to be predictors of an unfavorable neurological prognosis (p<0.05). Twenty-tree (43%) infants had clubfoot. Eighteen (78.3%) of these had abnormal leg movements. No infant in breech presentation (n=10) showed normal motor function. The presence of uterine contractions and the premature membrane rupture, observed in 13 fetuses (87%), were also linked to the alteration of neonatal muscular strength (p<0.05). CONCLUSION: clubfoot and breech presentation are ultrasonographic findings useful in predicting neurological neonatal outcome. Uterine contractions and premature membrane rupture are associated with poor motor neonatal outcome.

The present study aims to assess the feasibility and patient satisfaction of teleoncology orientation in a vulnerable population of breast cancer patients assessed in a government health system during the coronavirus pandemic in 2020.
Eligible patients received an invitation to receive remote care to minimize exposure to an environment in which the risk of respiratory infection was present. The means of communication was telephone through an application that allows free conversation with no charge. An anonymous-response questionnaire based on a Likert-type scale was sent through a cell phone application or e-mail directly to each patient or close relative of the patient immediately after teleconsultation. Responses to the questions, which addressed utility, facility, interface quality, interaction quality, reliability, satisfaction, and interest in future evaluation, were compiled and analyzed.
A total of 176 eligible patients scheduled for consultation were evaluated and 98 were included. Seventy (71.4%) successfully undertook the teleorientation. The questionnaire was submitted by 43 (61.4%) patients. The overall teleoncology orientation was classified as very positive by 41 (95.3%) patients. Specifically, regarding the questionnaire items, 43 (100%) patients scored 4 or 5 (agreed that the teleconsultation was beneficial) concerning the facility, followed by 42 (97.2%) for the interface quality, 41 (95.3%) for both utility and interaction quality, 40 (93%) for satisfaction and interest in future evaluation, and, finally, 39 (90.6%) for reliability.
Teleoncology orientation of low-income breast cancer patients is most feasible and leads to high patient satisfaction.
