RESUMEN

BACKGROUND: Vitamin D deficiency has been linked to the increased severity of numerous viral infections. OBJECTIVE: To assess whether vitamin D supplementation is safe and effective for the treatment of COVID-19. METHODS: We searched MEDLINE, EMBASE, CENTRAL, LILACS and LOVE for randomised controlled trials (RCTs) published up to 2 March evaluating the effects of vitamin D for the treatment of coronavirus disease (COVID-19). Two authors selected the studies and analysed the data evidence following Cochrane Recommendations. RESULTS: We included three RCTs with a total of 385 participants. We found low certainty evidence indicating that hospitalised patients under calcifediol plus standard care (SC) treatment seem to present a significantly lower risk of being admitted to ICU but no difference in mortality. We found low to very low certainty evidence that the improvement in fibrinogen levels is slightly greater in mildly symptomatic or asymptomatic patients with COVID-19 that used cholecalciferol plus SC than in those treated with placebo plus SC (mean difference), and the patients who used cholecalciferol plus SC achieved more SARS-CoV-2 negativity, but not on d-dimer, c-reactive protein (CRP) or procalcitonin compared with the patients in the placebo plus SC group. We also found low to moderate certainty evidence that a single high dose of vitamin D does not seem to be effective for reducing mortality, length of hospital stay, ICU admissions and d-dimer or CRP levels when used in patients with moderate to severe COVID-19. CONCLUSIONS: As a practical implication, the use of vitamin D associated with SC seems to provide some benefit to patients with COVID-19. However, the evidence is currently insufficient to support the routine use of vitamin D for the management of COVID-19, as its effectiveness seems to depend on the dosage, on the baseline vitamin D levels, and on the degree of COVID-19 severity.

RESUMEN

OBJECTIVE: Our study compared the amount of total collagen and type I collagen in ovular membranes of pregnant smokers and non-smokers. MATERIAL AND METHODS: The study group consisted of 14 pregnant smokers at 24-36 weeks of gestation; 39 pregnant non-smokers between 24-36 weeks of gestation comprised the control group. The expressions of total collagen and type I collagen were analyzed using two histological sections of the fetal membranes. The assessment of total collagen was performed using the Picro-Cirius red stain, and type I collagen expression was determined by means of immunohistochemistry The Mann-Whitney test was applied to verify possible differences between the groups. RESULT: The average area covered by total collagen was lower in smokers (20630.45 microm2) as compared to non-smokers (24058.61 microm2), although the difference was not statistically significant (p = 0.454). Comparison involving collagen type I deemed similar results (20001.33 microm2 vs. 25328.29 microm2, p = 0.158). CONCLUSION: The amount of total collagen and type I collagen was lower in ovular membranes of pregnant smokers as compared to non-smokers, although the difference was not statistically significant.

RESUMEN

PURPOSE: To evaluate the changes in quality of life (QOL) over a 1-year follow-up period in patients submitted to laparoscopic colorectal resection for the treatment of deep endometriosis. METHODS: A prospective observational cohort study (Canadian Task Force Design Classification II) involving 40 women with intestinal deep endometriosis was conducted between June 2007 and September 2008 at the Department of Obstetrics and Gynecology, Santa Casa Medical School, Sao Paulo, Brazil. Prior to the surgical procedure, all patients received magnetic resonance studies of the pelvis and rectal echoendoscopy, which suggested intestinal involvement of the disease in all cases. The patients received laparoscopic colorectal resections and treatment for other endometriotic lesions. The subjects completed the QOL SF-36 at 3 time points (T0 pre-operatively; T1 6 months post-operatively; and T2 1 year post-operatively). RESULTS: The physical functioning, role physical, social functioning and role emotional subscales evidenced the most substantial median increases for T0, T1 and T2. The pain, general health, vitality and mental health domains showed slight changes and increases in medians but did not increase to the same extent as the previous group. Significant improvements were observed in all domains of the SF-36 throughout the study period (p < 0.05). Physical health-related QOL domains showed greater improvement than mental health domains. Analyses of age, parity and body mass index as potential factors influencing the impact of surgery on QOL revealed no differences. Therefore, these factors were not used as prognostic indicators for the surgical procedure or for patient follow-up. In addition, we noted that the patients with poorest results on the initial QOL questionnaire showed the greatest improvements at the end point. CONCLUSION: The study results showed that laparoscopic colorectal segment resection for endometriosis had a positive impact on QOL in this patient group. The positive effects persisted 1 year after surgery.

RESUMEN

INTRODUCTION: Polycystic ovary syndrome (PCOS) is a prevalent disease affecting women of reproductive age. It may be associated with metabolic disorders such as insulin resistance (IR) and obesity. The anti-Mullerian hormone (AMH) levels seem to be higher in patients with PCOS. OBJECTIVE: The present study was designed to evaluate the association between AMH and insulin in women with PCOS with and without IR. METHODS: Cross-sectional study, including 86 patients, selected and divided into three groups: Group A: 26 women with PCOS and IR; Group B: 30 women with PCOS and without IR; and Group C: 30 controls without PCOS. RESULTS: We found significant difference between serum AMH levels in the group of women with PCOS and without IR when compared to the control group, thus showing that PCOS and IR play an important role in elevating the levels of this hormone. When the groups were compared with each other following adjustment for BMI, serum AMH levels were significantly higher in the group of women with PCOS and IR. CONCLUSION: AMH levels are significantly higher in patients with PCOS, particularly in those women with PCOS and IR. Nevertheless, larger samples are required to confirm these findings.

RESUMEN

Epignathus teratomas are rare tumors that originate in the region of the palate or pharynx and are known as Rathke pouch. They may be associated with other malformations such as a cleft palate and bifid tongue or nose. The prenatal diagnosis can be established by two-dimensional ultrasonography showing a heterogeneous mass protruding through the mouth of the fetus. The three-dimensional ultrasonography in rendering mode permits better understanding of this anomaly by the parents, facilitating the counseling. The importance of prenatal diagnosis lies in the fact that this tumor may obstruct the airways, thus leading to death at birth due to respiratory insufficiency. We report a case of prenatal diagnosis of epignathus teratoma in the 30th week of pregnancy by two-dimensional ultrasonography. We focus on the importance of three-dimensional ultrasonography in rendering mode for demonstrating the spatial relationships of the tumor with the oral cavity and provide correlations between the ultrasound images and the anatomopathological findings.

RESUMEN

Nipple-sparing mastectomy (NSM) is increasingly offered to women for therapeutic and prophylactic indications. Although, clinical series have been described, there are few studies describing risk factors for complications. The objective of this study is to evaluate the incidence of complications in a series of consecutive patients submitted to NSM and differences between clinical risk factors, breast volume, and different incision types. In a cohort-designed study, 158 reconstructed patients (invasive/in situ cancer and high risk for cancer) were stratified into groups based on different types of incision used (hemi-periareolar, double-circle periareolar, and Wise-pattern). They were matched for age, body mass index, associated clinical diseases, smoking, and weight of specimen. Also included were patients treated with adjuvant chemotherapy and postoperative radiotherapy. Mean follow-up was 65.6 months. In 106 (67 %) patients, NSM was performed for breast cancer treatment and in 52 (32.9 %) for cancer prophylaxis. Thirty-nine (24.6 %) patients were submitted to hemi-periareolar technique, 67 (42.4 %) to double-circle periareolar incision, and 52 (33 %) to Wise-pattern incision. The reconstruction was performed with tissue expander and implant-expander. Local recurrence rate was 3.7 % and the incidence of distant metastases was 1.8 %. Obese patients and higher weight of specimen had a higher risk for complications. After adjusting risk factors (BMI, weight of specimen), the complications were higher for patients submitted to hemi-periareolar and Wise-pattern incisions. This follow-up survey demonstrates that NSM facilitates optimal breast reconstruction by preserving the majority of the breast skin. Selected patients can have safe outcomes and therefore this may be a feasible option for breast cancer management. Success depends on coordinated planning with the oncologic surgeon and careful preoperative and intraoperative management. Surgical risk factors include incision type, obesity, and weight of breast specimen.

RESUMEN

OBJECTIVE: To estimate the prevalence of exposure to the SARS-CoV-2 virus among individuals living in restricted freedom. METHODS: A seroprevalence survey was carried out with the population of the female penitentiary of the Centro de Progressão Penitenciária (CPP) in Butantan (municipality of São Paulo), between June 24 and August 20, 2020. During this period, according to the Secretariat of Penitentiary Administration (SAP), the positivity of rapid tests among inmates ranged from 65% to 78%. The evaluation method used in the study was the "One Step COVID-19" rapid test (chromatography), from the company Wondfo, also using the RT-PCR method in symptomatic participants to confirm the viral condition. The study population consisted of 879 female inmates and 170 employees of the institution. RESULTS: The prevalence of total antibodies (IgG/IgM) against the SARS-CoV-2 virus in the total population of 1049 study participants was 6.1%; among the population of 879 inmates,a prevalence of 5.8% was observed, and among the institution's employees, 7.5%. CONCLUSIONS: The prevalence of covid-19 at the Butantan CPP was low, which is due to the implementation of simple prevention measures at the institution, such as the use of masks (with appropriate changes), emphasis on hygiene, hand washing and social distancing, in addition to other strategies, such as suspending inmates' visits from relatives and friends and cutting back on elective medical appointments and outside work.

RESUMEN

Bone mass was only previously studied in juvenile dermatomyositis/polymyositis (DM/PM) patients. Therefore, the objective this study was to evaluate the prevalence of osteoporosis and fractures in adult DM/PM. Forty female DM/PM and 78 age-, gender-, and BMI-matched healthy controls were studied. Medical charts and clinical interviews of all patients were evaluated for demographic and clinical data, including disease activity, cumulative doses of glucocorticoid, menarche and menopause age, and fractures. Bone mineral density (BMD) using dual X-ray absorptiometry (DXA) were measured at lumbar spine (L1-L4) and hip. A decreased BMD in lumbar spine [0.902 (0.136) vs. 0.965 (0.141) g/cm(2), P = 0.022] and femoral neck [0.729 (0.12) vs. 0.784 (0.127) g/cm(2), P = 0.027] was observed in patients compared to controls. In addition, osteoporosis was more frequent in patients than in controls in both lumbar spine (20 vs. 3.8%, P = 0.007) and the femoral neck (27.5 vs. 10.3%, P = 0.016). Moreover, a high prevalence of fractures was found in patients in comparison to healthy subjects (17.9 vs. 5.1%, P = 0.040; OR = 3.92; CI 95%:1.07-14.33). Comparing DM/PM patients with (n = 17) and without (n = 23) osteoporosis/fractures, significant differences were observed regarding age [56.8 (11.9) vs. 48.3 (13.2) years, P = 0.042], weight [62.05 (13.56) vs. 71.51 (11.46) kg, P = 0.022] and frequency of post menopausal women (94.1 vs. 65.2%, P = 0.0002). No differences were observed concerning height, lean mass, total fat mass, disease activity, mean value of creatine kinase, cumulative glucocorticoid dose, or bisphosphonate use. Logistic regression analysis revealed a negative association between the presence of osteoporosis/fractures and weight (OR: 0.92, 95% CI: 0.85-0.98; P = 0.016). This is the first study that analyzed bone mass in adult DM/PM patients and it demonstrated that about one quarter of these patients have osteoporosis/fracture.

RESUMEN

New biological markers are emerging trying to identify earlier cardiovascular high risk subjects. Myeloperoxidases have been involved in the role of atherosclerosis process, by the beginning of the endothelial dysfunction up to the plaque rupture and clinical manifestation, and it has been demonstrated that this enzyme has also a prognostic value. We aimed to assess myeloperoxidases levels in patients with polycystic ovary syndrome (PCOS) with insulin resistance (IR), considering that these women represent a high risk group for cardiovascular disease. We developed a transversal study, comprising 26 patients with PCOS and IR and 30 controls (PCOS without IR). IR was considered with HOMA-IR ≥3.0. IR absence was considered when HOMA-IR <3.0, triglycerides <200, BMI <28.7, and BMI<27.8 in patients with familial history of type 2 diabetes. All patients went through anamnesis, physical examination, transvaginal ultrasound, and blood samples. IR PCOS patients had higher levels of myeloperoxidase (22.3 × 18.1, p = 0.047), and also higher BMI. Myeloperoxidase levels correlated directly with insulin. In conclusion, IR PCOS young patients have higher myeloperoxidase levels.

RESUMEN

BACKGROUND: Bilateral mammaplasty or mastopexy is frequently used for oncoplastic objectives. However, little information has been available regarding outcome following immediate and delayed reconstruction. METHOD: Patients were divided into Group I (immediate reconstruction) and Group II (delayed reconstruction). Retrospective review was performed to compare complications, length of hospital stay, revision surgeries, and satisfaction. The associations between the complications with potential risk factors (timing, age, body mass index, smoking, and comorbid medical conditions) were analyzed. RESULTS: There were a total of 144 patients with a mean follow-up of 47 months. Of the 106 patients in Group I, complications occurred in 24 (22.6%), skin necrosis was observed in 7.5%, fat necrosis in 5.6%, and 6.6% patients developed local recurrence. Mean period of hospitalization was 1.89 days. Of the 38 patients of the Group II, complications occurred in 12 (31.5%), skin necrosis was observed in 7 (18.4%), fat necrosis in 4 (10.5%), and 5.2% patients developed local recurrence. Mean period of hospitalization was 1.35 days. Increased length of hospital stay greater than 1 day (P < 0.001) and the number of revision surgeries (P = 0.043) were associated with the timing of the reconstruction. In univariate analysis, no difference between groups was found with respect to complication incidence (P = 0.275); however, after adjusting for other risk factors, the probability of complications tend to be higher for Group II (OR = 2.65; 95% confidence interval = 1.01-7.00; P = 0.049). CONCLUSIONS: On the basis of the results of our study, the probability of complications tends to be higher for delayed reconstructions, and it is demonstrated that obesity and smoking are risk factors for complications. Ultimately, these data may facilitate the provision of individualized risk information for shared medical decision-making.

RESUMEN

OBJECTIVE: Hot flashes have a negative impact on the quality of life of women during the menopausal transition and thereafter. The progressive reduction in gonadal estrogen levels associated with aging promotes an accumulation of abdominal fat, dyslipidemia, and arterial hypertension, all of which are components of metabolic syndrome (MetS). The objective of the present study was to estimate the prevalence of hot flashes and evaluate their relationship with MetS in women ≥ 40 years of age. METHODS: This was a cross-sectional study involving women aged between 40 and 65 years. We used the Kupperman index to quantify the climacteric symptoms and the National Cholesterol Education Program Adult Treatment Panel III criteria for the diagnosis of MetS. RESULTS: 1,435 women were initially selected, and we obtained information from 647. The mean age at menopause was 45.99 years (SD 6.61 years) and the prevalence of hot flashes and MetS were 55.83% (95% CI: 52.35-59.25%) and 46.29% (95% CI: 44.75-52.53%), respectively. We identified a positive association between MetS and hot flashes (OR 1.16; 95% CI: 1.01-1.33). CONCLUSIONS: In women ≥ 40 years of age, hot flashes are highly prevalent and appear to be associated with MetS.

RESUMEN

OBJECTIVES: The outbreak of coronavirus disease (COVID-19) is a public health emergency of international concern. Inflammatory changes are part of COVID-19 pathophysiology and this might generate a higher thromboembolic risk in patients using combined hormonal contraception and menopausal hormone therapy. We aimed to discuss the main aspects related to this issue and propose management strategies for women affected by COVID-19. METHODS: This narrative review collected information from several articles published since the beginning of the outbreak of the new coronavirus disease about the pathophysiology, stage of the disease, the occurrence of thrombotic events, and the risk of thromboembolism in users of contraception and hormonal therapy. RESULTS: This article consolidates clinical parameters about the risk of venous thromboembolism in users of contraception and menopausal hormone therapy emphasizing the probable increase of that risk in women with suspected or confirmed COVID-19 and bringing safer recommendations. CONCLUSIONS: In this scenario, apart from the fundamental orientations of preventive measures, like social isolation and hygiene, it is important that all female health professionals have knowledge of the new rules and adopt safety measures, especially on the prescription of hormonal therapy and contraception.

RESUMEN

OBJECTIVE: To estimate the prevalence of accidental falls in women and to identify possible associations of sociodemographic, clinical and lifestyle variables with falls, in 2007 and 2014. METHODS: Two cross-sectional studies were performed, in 2007 and 2014, within the Projeto de Saúde de Pindamonhangaba (PROSAPIN - Pindamonhangaba Health Project), with women aged between 35 to 75 years. Probabilistic samples were selected among women living in the municipality and participating in the Health Family Strategy. Data collection included: face-to-face interview, anthropometric examination and blood test. The outcome variable "have you fallen in the last six months?" was raised during the interview. The prevalence of falls in 2007 and 2014 were estimated by score with a 95% confidence interval (95%CI). Multiple logistic regression models were constructed to identify the association of independent variables with the occurrence of falls for each year based on the odds ratio (OR). We used the Stata 14.0 software for statistical analysis. RESULTS: The prevalence of accidental falls were: 17.6% (95%CI 14.9-20.5) in 2007 and 17.2% (95%CI 14.8-19.8) in 2014. In 2007, factors associated with falls were: aged 50-64 years (OR = 1.81; 95%CI 1.17-2.80), high school (OR = 1.76; 95%CI 1.06-2.93), hyperuricemia (OR = 3.74; 95%CI 2.17-6.44), depression (OR = 2.07; 95%CI 1.31-3.27), poor sleep (OR = 1.78; 95%CI 1.12-2.82) and daytime sleepiness (OR = 1.86; 95%CI 1.16-2.99). In 2014, they were: aged 50-64 years (OR = 1.64; 95%CI 1.04-2.58), hyperuricemia (OR = 1.91; 95%CI 1.07-3.43) and depression (OR = 1.56; 95%CI 1.02-2.38), plus metabolic syndrome (OR = 1.60; 95%CI 1.03-2.47) and musculoskeletal pain (OR = 1.81; 95%CI 1.03-3.18). CONCLUSIONS: Falls occur significantly in women aged 50 years or over, indicating that they are not restricted to older adults and that there is a need to initiate preventive measures earlier. Both studies showed similar magnitudes of occurrence of accidental falls and reinforced their multifactorial nature. In addition, hyperuricemia may be a potential new factor associated with falls.

RESUMEN

OBJECTIVE: to evaluate the expression of aromatase in simultaneously invasive ductal carcinoma (IDC) and ductal carcinoma in situ (DCIS). METHODS: forty-five surgical samples were obtained from mastectomy and quadrantectomy with simultaneous IDC and DCIS of stage I and II patients. Aromatase was evaluated using antibodies anti-aromatase and the samples classified in accordance with the number and intensity of stained cells. RESULTS: Aromatase was expressed positively in 32(71%) and negatively in 13(29%) of the cases in the IDC. The same results were obtained in the DCIS showing a perfect positive correlation. In the normal epithelium,aromatase was positive in 19(42.2%) and negative in 26 (57.8%) and a positive correlation, statistically significant was obtained when compared with IDC and DCIS(p<0.01). Concerning the normal stroma, positivity was only 7 (15.5%) showing no correlation with aromatase expression. Aromatase was positive in 36(80%) of the tumor stroma and this result was statistically significant as in the IDC and DCIS. Comparing results of aromatase expression with nuclear grade, histological grade, tumor size and age no difference was found. CONCLUSION: our results demonstrated high correlation between aromatase expression in IDC, DCIS, normal epithelium and tumor stroma showing a possible autocrine and paracrine mechanism of this enzyme in breast cancer.

RESUMEN

OBJECTIVE: Vitamin D plays an important role in bone metabolism. There is now evidence that a higher serum level of 25-hydroxyvitamin D (25[OH]D) is associated with a lower risk of developing type 2 diabetes mellitus, because it provides better glycemic control, possibly by promoting greater insulin sensitivity, and also by improving pancreatic beta cell function. The objective of the present study was to evaluate the possible association between 25(OH)D sufficiency and glycemia. METHODS: This was a cross-sectional study involving 680 women, 35 to 74 years of age, selected through systematic sampling. From each participant, fasting blood samples were collected for the determination of 25(OH)D and glucose levels. RESULTS: The mean fasting blood glucose level was 105 mg/dL (range 26-401 mg/dL). Fasting serum levels of 25(OH)D were <30 ng/mL in 65.4% of the participants and <20 ng/mL in 25.6%. A serum 25(OH)D level <30 ng/mL was positively associated with a blood glucose level ≥100 mg/dL (odds ratio [OR] 1.29, 95% confidence interval [CI] 1.05-1.57), as was a serum 25(OH)D level <20 ng/mL (OR 1.25, 95% CI 1.04-1.50). CONCLUSIONS: Lower serum 25(OH)D concentrations appear to be associated with a high blood glucose levels.

RESUMEN

BACKGROUND: Hypovitaminosis D is considered a global public health issue. Knowledge of its true dimensions will allow us to design interventions and plan preventive measures that can have a significant impact on human health. OBJECTIVES: The aim of this study was to evaluate the prevalence of hypovitaminosis D, defined as a serum 25-hydroxyvitamin D concentration < 30 ng/ml, in postmenopausal women around the world, as well as to identify the potential associated factors. METHODS: A systematic review was performed in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analyses recommendations. Specific search terms were consulted in Medline, Excerpta Medica, and Latin-American and Caribbean Health Sciences Literature databases, with no restriction for the year or language of publication. RESULTS: Of 451 studies initially identified, 32 were selected for analysis. Collectively, those 32 studies evaluated 21,236 postmenopausal women, of whom 16,440 (77.4%) had serum 25-hydroxyvitamin D concentrations < 30 ng/ml. The reported prevalence of hypovitaminosis D ranged from 29% (in the United States) to 99.4% (in China). In six of the studies, the prevalence was above 90%. CONCLUSIONS: If the criterion is the 30 ng/ml cut-off point, the majority of postmenopausal women in the world could be classified as having hypovitaminosis D. Among the studies evaluated, the lowest prevalence reported was nearly 30%. Neither latitude, region of the world, nor laboratory methodology were found to be associated with the prevalence of hypovitaminosis D.

RESUMEN

OBJECTIVE: To assess the prevalence of high-risk genital human papillomavirus (HPV) infection by age group and risk factors associated. METHODS: Cross-sectional study in a sample of 2,300 women (15-65 years old) who self-referred to cervical cancer screening in Sao Paulo and Campinas, Southeastern Brazil, between February 2002 and March 2003. An epidemiological questionnaire was applied and cervical specimens were obtained for cytology and hybrid capture II test (HCII) for HPV detection. Statistical analysis included Pearson Chi-square and unconditional multiple logistic regression model (forward likelihood ratio). RESULTS: High-risk genital HPV infection prevalence in this sample was 17.8% and age distribution was as follows: 27.1% (<25 years), 21.3% (25-34 years), 12.1% (35-44 years), 12.0% (45-54 years) and 13.9% (55-65 years). Subjects with the highest number of lifetime sexual partners had the highest rates of genital HPV infection. To be living with a partner, aged 35 to 44 years, and former smokers were protective factors. High-risk genital HPV infection was 14.3% in normal cytology, 77.8% in high grade squamous intraepithelial lesions and in the two cases (100%) of cervical cancer. CONCLUSIONS: High-risk HPV prevalence was high in the sample studied. The highest prevalence of HPV infection was seen in women under 25 years old and then a new increase was seen over the age of 55 and the highest rates were found among those with many sexual partners during their lifetime.

RESUMEN

OBJECTIVE: To describe the incidence and mortality by AIDS in Brazil involving women in the menopause transition and post-menopause stage. METHODS: Retrospective study conducted from 1996 to 2005, using secondary data provided by the DATASUS Health Information System - Ministry of Health. The population was extracted from the "Demographic and Socio-economic" database, incidence from "Epidemiology and Morbidity" and mortality from "Vital Statistics". Specific coefficients for incidence and mortality by AIDS (for 100,000 women) were calculated for each age ranging from 30 to 69 (30-39, 40-49, 50-59, 60-69) as this includes the population of interest; i.e. women in menopause transition and post-menopause, that is to say from 35 to 65 years of age. RESULTS: There was an increase in the incidence of AIDS between 1996 and 1998, followed by a slight downward trend until 2000 and then an increment up to 2004. In 2005, the coefficient returns to values close to those of 1997. Mortality fell in all age ranges from 1996 to 1997 and afterwards coefficients remained virtually stable until 1999, except for ages from 30-39, which continue stable until 2005. For women older than 40, the mortality coefficient increased between 1999 and 2005. CONCLUSION: There was an increase in the number of new cases of AIDS in women over 30 and the same was true for mortality. The increase and "aging" of epidemics among Brazilian women show that health supporting measures, disease prevention and early diagnoses as well as effective care must be provided for women in the 30-69 age group considering personal characteristics, family context and social role played by women of this age.

RESUMEN

A hiperplasia adrenal congênita (HAC) pode cursar com redução da fertilidade na mulher. Entretanto, nos casos em que ocorre gestação, os recém-nascidos das por- tadoras de hiperplasia adrenal congênita exibem risco de hiperandrogenismo, com todas as suas consequências. A presente revisão atualiza o tema, considerando também as necessidades da assistência a essas pacientes. A busca identificou 294 artigos na base de dados MEDLINE/PubMed de 1961 a março/2023, e os resultados mostraram que as portadoras de hiperplasia adrenal congênita exibem significativa redução da fertilidade. Nos casos de interesse de gestação, as portadoras de hiper- plasia adrenal congênita devem fazer um planejamento reprodutivo, envolvendo a fase antenatal, o acompanhamento pré-natal especializado, o parto e o aleitamento.


Congenital adrenal hyperplasia may lead to reduced male and female fertility. Mo- reover, when the pregnancy occurs, the newborns of patients with congenital adrenal hyperplasia are at risk of hyperandrogenism with all its consequences. This review updates the theme and emphasizes assistance needs. The search identified 294 ar- ticles in the MEDLINE/PubMed database from 1961 to March/2023, and the results showed that patients with congenital adrenal hyperplasia truly exhibit a significant reduction in fertility. In cases of interest in pregnancy, patients with congenital adre- nal hyperplasia should carry out reproductive planning, involving the antenatal pha- se, specialized prenatal care, till delivery and breastfeeding.

RESUMEN

Objective To evaluate the expression of survivin protein in low- and high-grade ductal carcinoma in situ. Methods Breast tissue fragments obtained by incisional biopsy and surgical procedures of 37 women with ductal carcinoma in situ of the breast were subdivided into two groups: Group A, composed of women with low-grade ductal carcinoma in situ, and Group B, women with high-grade ductal carcinoma in situ. Survivin protein expression test was performed by immunohistochemistry, using a monoclonal antibody clone I2C4. The criterion to evaluate survivin immunoexpression was based on the percentage of neoplastic cells that presented brown-gold staining. This criterion was positive when the percentage of stained cells was ≥10%. Results The survivin protein was expressed in 22 out of 24 cases of high-grade ductal carcinoma in situ (78%), whereas, in Group A, of low-grade ductal carcinoma in situ (n=13), it was positive in only 6 cases (21.40%; p=0.004). Conclusion The frequency of expression of survivin was significantly higher in the group of patients with high-grade ductal carcinoma in situ compared to those in the low-grade ductal carcinoma in situ group.
