RESUMO

OBJECTIVE: Ultrasonographic evaluation of the postpartum uterus to prevent retained placental tissue complications is still a matter of debate, and it is difficult to interpret its necessity on the basis of previous studies. We hypothesized that the application of uterotonics on the basis of regular postpartum ultrasound scanning of the uterus may reduce the number of unnecessary curettages in a large unselected population. METHODS: This was a cross-sectional observational study conducted among mothers (n = 6,028) delivering at two different (secondary and tertiary) hospitals to analyze the benefit of postpartum uterine ultrasound for clinical implications. Women delivering at the secondary care unit (n = 1,915) had no regular postpartum ultrasound scans in comparison to those delivering at the tertiary unit (n = 4,113). On regular ultrasound scans, morphological findings in the uterine cavity were recorded. Upon the presence of an intrauterine hyperechogenic mass larger than 2 cm in diameter, mothers received a single dose of uterotonics (methylergometrin 0.2 mg or oxytocin 5 IU) intramuscularly and control sonography after 24 h. In case of intrauterine mass persistence and serious postpartum hemorrhage women underwent a surgical intervention. The management was similar at the secondary unit, but ultrasound scans were provided only when there was a clinical finding. All patients were followed-up 6 weeks after labor. RESULTS: Women delivering at the secondary institution experienced a higher incidence of puerperal surgical interventions (1.51 vs. 0.87%) and lower agreement between sonography and histological findings (72.4 vs. 86.1%) compared with women delivering at the tertiary care unit, respectively (P < 0.05), where the general incidence of interventions was 1.10% after spontaneous and 0.19% after cesarean deliveries. In addition, trained sonographers reached only 13.9% false-positive ultrasound scans. Time-dependent regression analysis of uterine morphological involution variables showed a significant association between uterine length, width, uterine cavity and cervical channel mass, P < 0.0001, P < 0.01, P < 0.05, P < 0.05, respectively, and insignificant association between uterine cavity volume with an increased time period postpartum. CONCLUSIONS: In this study, routine ultrasound evaluation of the uterus in the postpartum period with regular application of uterotonics decreased the rate of surgical interventions. We strongly advise the introduction of postpartum uterine scanning into obstetrical practice, most suitably provided around day 3 after delivery.

RESUMO

Ductus venosus waveform analysis has become increasingly affected by technical errors; however, these errors could be avoided if more attention was paid during sampling and analysis. The most common misevaluations include incorrect tracing, under- or overestimation of the peak systolic velocity, overestimation of the end-diastolic velocity, and, as a consequence, incorrect calculation of the pulsatility index facilitated either by human or software error. This article proposes practical suggestions to avoid technical errors in ductus venosus waveform analysis.

RESUMO

Spontaneous regression of malignant tumors is a rare event. It is defined as partial or total disappearance of a proven malignant tumor without adequate medical treatment. The causes of this phenomenon are various. Nevertheless, malignant tumors do regress occasionally for no apparent reason, as evidenced by many clinical observations. We report a case of a 68-year-old woman, who was presented with a several-month history of a painless firm lump, initially of 1 cm in diameter and growing to a large solid regular tumor of 2.5 x 2.5 cm in size, in the upper outer quadrant of her right breast. Preoperative histopathological diagnosis revealed ductal invasive carcinoma. Later on, while awaiting surgical treatment, she suffered an arm injury requiring a 1-month delay of surgery. After recovery, on the date of surgery the tumor disappeared, and, in addition, it was not found in tissue specimens obtained from quadrantectomy. After 78 months of follow-up there was no evidence of relapse. In this report, we discuss clinical and histopathological findings, patient management and possible mechanisms of cancer regression.

RESUMO

Studies on the association between the Ile to Val polymorphism at codon 655 of the human epithelial growth factor receptor 2 (HER-2) gene and susceptibility to breast cancer have been reported for almost all ethnic populations, with both positive or negative conclusions. No study, however, has yet been focused on the possible association between this gene and its predisposition to benign breast lesions, especially on risk for fibroadenoma. We aimed to study the association of the single nucleotide polymorphism V655 HER-2 gene polymorphism with histologically verified breast fibroadenoma risk. We conducted a molecular epidemiological case-control study of 70 breast fibroadenoma cases without cellular atypia and 172 healthy female controls. We found that the Val variant allele and genotype frequency of this polymorphism is higher in cases with fibroadenoma; however, this difference was not significant (allele Val 655: 27.86 and 22.67% in fibroadenoma and controls, respectively; genotype Ile/Val: 35.71 and 38.37% and Val/Val: 10.0 and 3.49% in fibroadenoma and controls, respectively). Applying logistic regression analysis, we found an increased risk of fibroadenoma formation in carriers of the Val allele (odds ratio = 1.17; 95% confidence interval = 0.67-2.05), in which the highest risk was associated with homozygous genotype (odds ratio = 3.07; 95% confidence interval = 0.97-9.72), but this risk was not significant. Stratification by age (cut-off 45 years) revealed the highest risk of fibroadenoma among young women homozygous for the Val allele (odds ratio = 3.30). The risk, however, was slightly increased (odds ratio = 1.24) among older carriers of the aberrant allele in their genotype as well, but it was not significant. In spite of insignificant differences, our results indicate that HER-2 Ile655Val polymorphism, especially in a homozygous form might play some role in the etiology of breast fibroadenoma formation. The significance of this susceptibility, however, will have to be verified by larger studies.

RESUMO

OBJECTIVES: To assess ductus venosus (DV) indices during the first stage of labor and the effect of ruptured membranes, meconium stained liquor and epidural analgesia (EDA). METHODS: Prospective cross-sectional study. Eighty-one women with low-risk singleton term pregnancies participated, 51 had normal labor (Group 1), and 30 experienced ruptured membranes and/or stained liquor (Group 2). Of the latter group 14 received EDA. The effect of various interventions and application of EDA on the ductus venosus index (DVI) and pulsatility index for veins (DV PIV) were tested. RESULTS: The feasibility rate was 94%. A significant increase of DV indices (DVI, DV PIV) was found in group 2 (P<0.001 and P<0.0005, respectively). The A-velocity was also significantly lower in group 2 (P<0.02). A markedly significant increase of DV indices (P<0.0001) among participants receiving EDA was observed in group 2. The mean+/-SD indices were: 0.53+/-0.10 for the DVI and 0.68+/-0.14 for the DV PIV in those women. There was a significant positive correlation of DV indices with the duration of amniorrhea in group 2 (PIV: r=0.66; P<0.002; DVI: r=0.68; P<0.001). CONCLUSIONS: Long-term amniorrhea seems to affect the fetal venous circulation reflected in increased DV waveform indices.

RESUMO

Solitary fibrous tumor (SFT) is a rare mesenchymal tumor that occurs preferentially in the pleura. Although it has been described at some extrathoracic sites, its occurrence in the female genital tract is extremely rare. We are the first to report on an unusual case of a large (14cm in the largest diameter) SFT localized in the broad ligament of the uterus in a 50-year-old woman. The patient underwent surgical tumor extirpation and has remained well without any sign of local tumor recurrence after 6 years of follow-up. We discuss the clinical aspects, the gross macroscopic appearance, the histologic findings, and the differential diagnosis, and provide a review of the literature.

RESUMO

It is known that BRCA genes play central roles in hereditary breast and ovarian cancers. BRCA1 mutation carriers face a cumulative lifetime risk of ovarian and breast cancer development. We report on a case of a strong family prevalence of BRCA1 linked malignancies as an immense psychological encumbrance and reason of demand for radical prophylactic risk decreasing surgeries in a 29 year-old healthy woman with proved 3889delAG BRCA1 gene mutation on exon 11, codon 1265 in effort to prevent possible malignant changes in the ovaries and the breast. Problems regarding the management of asymptomatic BRCA mutation carriers, time and impact of early prophylactic surgery in young women are discussed with a review of recent literature.
