RESUMO

OBJECTIVE: This study examines the electromyography pattern of abdominal trigger points developed after a caesarean section, and the association between clinical response and local anaesthetic injection. DESIGN: Prospective cohort study. SETTING: A tertiary university hospital. POPULATION: Twenty-nine women with chronic pelvic pain associated with trigger points after a caesarean section were included in the study. METHODS: Participants received needle electromyography before treatment, then underwent a treatment protocol consisting of trigger-point injection of 2 ml of 1% lidocaine. The protocol was repeated once a week for 4 weeks. The clinical responses of the patients were compared 1 week after and 3 months after treatment. The clinical trial is registered with the Brazilian Clinical Trials Registry (REBEC) under RBR-42c6gz (www.ensaiosclinicos.gov.br/rg/RBR-42c6gz/). MAIN OUTCOME MEASURES: Needle electromyography and algometry results and pain reduction. RESULTS: Fifteen patients had abnormal electromyography findings; 14 had normal findings. The rates of response 1 week and 3 months after treatment within the abnormal electromyography group were 95 and 87%, respectively. In the normal group, the rate was 38% both 1 week after and 3 months after treatment. CONCLUSIONS: Trigger points developed after caesarean section, even without clinical symptoms or signs of neuralgia, may originate from neuropathies. Electromyographic abnormalities were associated with pain remission after anaesthesia injection; normal electromyography findings were associated with undiagnosed causes of pain, such as adhesions. TWEETABLE ABSTRACT: Trigger points developed after caesarean section are neuropathies, even in the absence of classical neuralgia.

RESUMO

Cystic fibrosis (CF) is a common autosomal recessive disorder, being the p.F508del the most frequent mutation. Also, a nearby restriction fragment length polymorphism (RFLP) named XK (KM19 and XV2C) is non-randomly associated with specific CF alleles. Our aim was to analyze the occurrence of the p.F508del mutation and XK haplotypes in Afro-Brazilians CF patients and controls, since these data is available for the other two main ethnic groups found in Brazil (Euro-Brazilians and Brazilian Amerindians), contributing for the whole comprehension of these haplotypes in the Brazilian population. A total of 103 patients and 54 controls were studied. PCR and PCR-RFLP methodologies were used to identify the presence of the p.F508del and the XK haplotype in the subjects. The combined data show that 84.2% of p.F508del mutation is associated with haplotype B and only 15.8% with haplotype A; no other haplotypes were found to be associated with this mutation. Our data suggest that the occurrence of p.F508del mutation and haplotype B in Afro-Brazilian patients occurs probably due to admixture with Euro-descendants. Therefore this mutation and haplotype could be used as a admixture marker.

RESUMO

OBJECTIVES: To evaluate the expression of four genetic markers (PTEN, BCL2, MLH1, and CTNNB1), linked to endometrial carcinogenesis, in endometrial polyps of patients with and without postmenopausal bleeding in order to determine whether symptomatic endometrial polyps have a genetic phenotype similar to that of endometrial cancer. METHODS: Samples were obtained hysteroscopically from endometrial polyps of postmenopausal patients, and the expression of genetic markers involved in the pathogenesis of endometrial cancer (PTEN, BCL2, MLH1, and CTNNB1) was analyzed. The expression of these markers was then compared between patients with and without symptoms, which was characterized as postmenopausal bleeding. Other clinical characteristics of the patients, such as duration of menopause, polyp size, presence of systemic hypertension, diabetes mellitus, and smoking habits were also analyzed. RESULTS: Samples from a total of 60 patients were obtained, as calculated for a test power of 0.80. No statistical differences (p > 0.05) were observed between the two groups concerning the expression of the studied endometrial cancer risk factor genes, or with regard to the clinical aspects evaluated. CONCLUSION: The study found no evidence that symptomatic endometrial polyps have a similar phenotype to type 1 endometrial cancer; further studies are needed in order to establish whether endometrial polyps are in fact true cancer precursors, or simply raise cancer incidence due to a detection bias.

RESUMO

PURPOSE OF INVESTIGATION: To assess the accuracy of CA-125 determination associated with clinical history and of the neutrophil/lymphocyte (N/L) ratio for a presumptive diagnosis of endometriosis in women with chronic pelvic pain (CPP). MATERIALS AND METHODS: This was a cross-sectional study of data from the medical records of women with CPP submitted to laparoscopy from August 1999 to January 2009 at the University Hospital. The performance of the evaluation of CA-125 and of the N/L ratio for the prediction of endometriosis was compared based on the corresponding ROC curves and their 95% confidence intervals. RESULTS: CA-125 levels were significantly higher in women with CPP and endometriosis and their association with a complaint of dysmenorrhea improved their sensitivity. For a cut-off of 20 IU/ml, the predictive value for a diagnosis of endometriosis in women with CPP was 97.6%. Dyspareunia, subfertility, and N/L ratio were not useful for a diagnosis of endometriosis in women with CPP. CONCLUSION: The association of elevated CA-125 levels with a complaint of dysmenorrhea is adequate in a presumptive and accurate diagnosis of endometriosis in this specific group of women with CPP, permitting an early institution of clinical treatment without the need of previous laparoscopic confirmation.

RESUMO

In this study, we identified miRNAs and their potential mRNA targets that are intricately linked to primary chemotherapy response in patients with invasive ductal carcinomas. A cohort of individuals diagnosed with advanced invasive breast ductal carcinoma who underwent primary chemotherapy served as the cornerstone of our study. We conducted a comparative analysis of microRNA expression among patients who either responded or did not respond to primary systemic therapy. To analyze the correlation between the expression of the whole transcriptome and the 24 differentially expressed (DE) miRNAs, we harnessed the extensive repository of The Cancer Genome Atlas (TCGA) database. We mapped molecular mechanisms associated with these miRNAs and their targets from TCGA breast carcinomas. The resultant expression profile of the 24 DE miRNAs emerged as a potent and promising predictive model, offering insights into the intricate dynamics of chemotherapy responsiveness of advanced breast tumors. The discriminative analysis based on the principal component analysis identified the most representative miRNAs across breast cancer samples (miR-210, miR-197, miR-328, miR-519a, and miR-628). Moreover, the consensus clustering generated four possible clusters of TCGA patients. Further studies should be conducted to advance these findings.

RESUMO

PREDICT is a tool designed to estimate the benefits of adjuvant therapy and the overall survival of women with early breast cancer. The model uses clinical, histological, and immunohistochemical variables. This study aimed to evaluate the model's performance in a Brazilian population. We assessed the discrimination and calibration of the PREDICT model to estimate overall survival (OS) in five and ten years of follow-up in a cohort of 873 women with early breast cancer diagnosed from January 2001 to December 2016. A total of 743 patients had estrogen receptor (ER)-positive and 130 had ER-negative tumors. The area under the receiver operating characteristic (ROC) curve (AUC) for discrimination was 0.72 (95%CI: 0.66-0.78) at five years and 0.67 (95%CI: 0.61-0.72) at ten years for women with ER-positive tumors. The AUC was 0.72 (95%CI: 0.62-0.81) at five years and 0.67 (95%CI: 0.54-0.77) at ten years for women with ER-negative tumors. The predicted survival in ER-positive tumors was 91.0% (95%CI: 90.2-91.6%) at five years and 79.3% (95%CI: 77.7-81.0%) at ten years, and the observed survival 90.7% (95%CI: 88.6-92.9%) and 77.2% (95%CI: 73.4-81.4%), respectively. The predicted survival in ER-negative tumors was 84.5% (95%CI: 82.5-86.6%) at five years and 75.0% (95%CI: 71.6-78.5%) at ten years, and the observed survival 76.3% (95%CI: 69.1-84.3%) and 67.9% (95%CI: 58.6-78.6%), respectively. In conclusion, PREDICT was accurate to estimate OS in women with ER-positive tumors and overestimated the OS in women with ER-negative tumors.

RESUMO

The objective of this study was to evaluate the immunohistochemical expression of Dicer, Drosha, and Exportin-5 in the eutopic and ectopic endometrium of women with adenomyosis. Twenty-two paired ectopic and eutopic endometrium from women with adenomyosis and 10 eutopic endometrium samples from control women undergoing hysterectomy were included in the study. Paraffin-embedded tissue blocks were cut and stained for immunohistochemistry. The percentage of epithelial cells positively marked was identified digitally after an automated slide scanning process. Mann-Whitney test or Wilcoxon signed-rank test was performed for independent and paired groups, respectively. A lower expression of Drosha was observed in the eutopic endometrium of women with adenomyosis than in the eutopic endometrium of women without the disease (69.9±3.4% vs 85.2±2.9%, respectively) (P=0.016; 95%CI: 3.4 to 27.4%). We also detected lower Drosha expression in the ectopic endometrium of women with adenomyosis than in the eutopic endometrium of the same women (59.6±3.2% vs 69.9±3.4%, respectively) (P=0.004; 95%CI: 2.3 to 16.7%). Additionally, we observed a correlation between Drosha expression in the ectopic and paired eutopic endometrium (P=0.034, rho=0.454). No significant difference in Dicer or Exportin expression was observed. Predominant pattern of cytoplasmic staining for the anti-Drosha antibody and both a nuclear and cytoplasmic pattern for the anti-Exportin antibody were observed. Drosha expression was significantly lower in the endometrium of women with adenomyosis compared to the eutopic endometrium of asymptomatic women without the disease. Furthermore, its expression was lower in the ectopic endometrium but correlated to the paired eutopic endometrium.

RESUMO

BACKGROUND: The Choosing Wisely initiative aims to promote discussions among healthcare professionals and patients about low-value, or potentially harmful, health practices. OBJECTIVES: To describe the process of development of the Brazilian Choosing Wisely list for musculoskeletal physical therapy. METHODS: The Brazilian Choosing Wisely list was developed in accordance with the recommendations of the American Board of Internal Medicine. A three-step procedure was used. First, an expert panel was selected, and a modified Delphi approach was used to obtain a list of evidence-based statements. Second, members of the research team performed content analysis. Third, a national survey was conducted to present selected statements to a sample of physical therapists. Participants were invited to vote considering the level of importance of selected statements for physical therapists and patients. RESULTS: The expert panel comprised 17 physical therapists. The median age of the expert panel was 33 [interquartile range (IQR) 29 to 37; range 26 to 60] years and the median length of professional experience was 12 (IQR 10 to 18) years. A list of eight recommendations was presented to a national sample composed of 1127 physical therapists. The median length of professional experience of the national sample was 10 (IQR 5 to 15) years. Based on the number of votes, the five most important recommendations were included in the Brazilian Choosing Wisely list for musculoskeletal physical therapy. Descriptive and frequency analysis were used to report the results. CONCLUSION: The Brazilian Choosing Wisely list for musculoskeletal physical therapy provides an opportunity for physical therapists, patients, society and policy makers to collaboratively discuss tests and treatments that are unnecessary or potentially harmful.

RESUMO

Obesity has been associated with an increased risk of breast cancer recurrence and death. Some readily available biomarkers associated with systemic inflammation have been receiving attention as potential prognostic indicators in cancer, including neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR). This study aimed to explore the correlation between body mass index (BMI) and invasive breast cancer and the association of NLR, PLR, and BMI with breast cancer outcomes. We undertook a retrospective study to evaluate patients treated for breast cancer over 14 years. Clinicopathological data was obtained before receiving any treatment. Of the 1664 patients included with stage I-III, 567 (34%) were obese (BMI≥30 kg/m2). Obese patients had larger tumors compared to non-obese patients. Higher BMI was associated with recurrence and worse survival only in patients with stage I disease. NLR and PLR were classified into high and low level groups. The NLRhigh (NLR>4) was found to be an independent prognostic factor for recurrence and mortality, while the PLRhigh (PLR>150) group had no impact on survival. A subgroup of patients with NLRhigh and BMIhigh had the worst disease-free survival (P=0.046), breast cancer-specific survival (P<0.001), and overall survival (P=0.006), compared to the other groups. Patients with early-stage breast cancer bearing NLRhigh and BMIhigh had worse outcomes, and this might be explained by the dysfunctional milieu of obesity in adipose tissue and its effects on the immune system. This study highlights the importance of lifestyle measures and the immune system interference with clinical outcomes in the early breast cancer setting.

RESUMO

BACKGROUND: Some ovarian metaplasias may contain bone or osteoid tissue. The most common tumors presenting these alterations are teratomas and mixed mesodermal tumors with heterologous elements. CASE REPORT: We report the case of a woman who, during gynecologic follow-up for chronic anovulation at the age of 31 years, presented a solid ovarian ultrasonographic image with calcifications. After laparoscopy and histological examination it was found to be an isolated ovarian osseous metaplasia. CONCLUSION: A rarely occurring condition, ovarian osseous metaplasia continues to be of uncertain clinical significance.

RESUMO

BACKGROUND: Chronic pelvic pain (CPP) is a common and complex disease whose cause is often clinically inexplicable, with consequent difficulty in diagnosis and treatment. Patients with CPP have high levels of anxiety and depression, with a consequent impairment of their quality of life. AIMS: The objective of this study was to determine the prevalence of anxiety and depression and their impact on the quality of life of women with CPP. MATERIALS AND METHODS: A cross-sectional controlled study was conducted on 52 patients with CPP and 54 women without pain. Depression and anxiety were evaluated by the Hospital Anxiety and Depression Scale, and quality of life was evaluated by the World Health Organization Quality of life Whoqol-bref questionnaire. Data were analysed statistically by the Mann-Whitney U-test, the Fisher exact test, chi-square test and Spearman correlation test. RESULTS: The prevalence of anxiety was 73% and 37% in the CPP and control groups, respectively, and the prevalence of depression was 40% and 30% respectively. Significant differences between groups were observed in the physical, psychological and social domains. Patients with higher anxiety and depression scores present lower quality of life scores. DISCUSSION: The fact that DPC is a syndromic complex, many patients enter a chronic cycle of search for improvement of medical symptoms. The constant presence of pain may be responsible for affective changes in dynamics, family, social and sexual. Initially the person is facing the loss of a healthy body and active, to a state of dependence and limitations. In this study, patients with higher scores of anxiety and depression scores had lower quality of life and patients with lower scores of anxiety and depression had scores of quality of life. These results show that perhaps the depression and anxiety may be related to the negative impact on quality of life of these patients. CONCLUSION: In view of this association, we emphasise the importance of a specific approach to the treatment of anxiety and depression together with clinical treatment to improve the quality of life of these patients.

RESUMO

INTRODUCTION: Endometriosis is a benign, estrogen-dependent, chronic gynecological disorder associated with pelvic pain and infertility. The disease most commonly affects women during the reproductive age, although postmenopausal patients do rarely present it. These rare occurrences are generally associated with hormonal use. MATERIAL AND METHODS: We present three cases of endometriosis in postmenopausal patients who have no history of hormone therapy and no previous history of endometriosis or infertility. CASE REPORTS: In case 1, a 62-year-old woman presented with acyclic pelvic pain and a left ovarian homogeneous cystic mass. After laparoscopic salpingoophorectomy and histological analysis, an ovarian endometriotic cyst was confirmed. In case 2, a 78-year-old woman presented with a painful abdominal wall mass that was confirmed by ultrasound and tomography. Her past medical history included an abdominal hysterectomy 20 years prior to the discovery of this mass. The lesion was surgically excised and histological analysis showed areas of endometrial stroma and glands surrounded by fibrosis, compatible with endometriosis. In case 3, a 54-year-old woman presented with chronic pelvic pain and a nodule in the rectovaginal septum was noted during gynecological examination. Menopause occurred at 48 years of age. She had no previous dysmenorrhea. Ultrasound confirmed the nodule in the rectovaginal septum. The patient was submitted to a diagnostic colonoscopy that revealed a friable lesion, which was subsequently biopsied. The histological diagnosis was endometriosis. CONCLUSIONS: These three cases of postmenopausal endometriosis support the celomic metaplasia theory for the genesis of this disease.

RESUMO

The objective of this prospective study was to determine the plasma levels of nitric oxide (NO) in women with chronic pelvic pain secondary to endometriosis (n=24) and abdominal myofascial pain syndrome (n=16). NO levels were measured in plasma collected before and 1 month after treatment. Pretreatment NO levels (µM) were lower in healthy volunteers (47.0±12.7) than in women with myofascial pain (64.2±5.0, P=0.01) or endometriosis (99.5±12.9, P<0.0001). After treatment, plasma NO levels were reduced only in the endometriosis group (99.5±12.9 vs 61.6±5.9, P=0.002). A correlation between reduction of pain intensity and reduction of NO level was observed in the endometriosis group [correlation = 0.67 (95%CI = 0.35 to 0.85), P<0.0001]. Reduction of NO levels was associated with an increase of pain threshold in this group [correlation = -0.53 (-0.78 to -0.14), P<0.0001]. NO levels appeared elevated in women with chronic pelvic pain diagnosed as secondary to endometriosis, and were directly associated with reduction in pain intensity and increase in pain threshold after treatment. Further studies are needed to investigate the role of NO in the pathophysiology of pain in women with endometriosis and its eventual association with central sensitization.

RESUMO

A retrospective observational study was carried out to analyze the correlations between formal pulmonary function tests and the Shwachman-Kulczycki (SK) score. Forty-six Brazilian cystic fibrosis (CF) patients, clinically stable, aged 7-19 years, were included. Clinical and radiological findings of the SK score system and spirometry variables were assessed by independent observers in a blinded manner. The strongest correlation (r = 0.75; 95% CI, 0.59-0.85; P < 0.001) was found for forced expiratory volume in 1 sec (FEV1). Despite some peculiarities of our patients, the results are in agreement with studies undertaken in industrialized countries, showing good correlation between FEV1 and SK score and its usefulness in managing CF. Accordingly, in countries where pulmonary function testing is not available, the SK score remains a valuable parameter on which to base treatment results.

RESUMO

The objective of the present study was to determine the possible prognostic factors which may explain the difference in the survival of patients with cystic fibrosis (CF) with and without meconium ileus. Over a period of 20 years, 127 patients with CF, whose diagnosis was confirmed by typical clinical characteristics and altered sweat chloride levels, were studied retrospectively. The patients were divided into two groups: group 1 consisted of patients who presented CF and meconium ileus (N = 9), and group 2 consisted of patients with CF without meconium ileus (N = 118). The characteristics studied were based on data obtained upon admission of the patients using a specific protocol. Demographic, clinical, nutritional and laboratory data were obtained. The genotype was determined in 106 patients by PCR. Survival was analyzed using the Kaplan-Meier method. The median follow-up period was 44 months. A statistically significant difference was observed between the groups studied regarding the following variables: age at diagnosis and weight and height z scores. The presence of meconium ileus was associated with an earlier diagnosis; these patients had greater deficits in height and weight at the time of diagnosis and at the end of the study. The estimated probability of survival for patients with CF without meconium ileus was 62 +/- 14% and for those with meconium ileus 32 +/- 18%. Patients with CF and meconium ileus presented a poor nutritional status at diagnosis and a lower survival rate compared to the general CF population.

RESUMO

OBJECTIVE: To determine if the history of cesarean section was associated with chronic pelvic pain, independent of the presence of other conditions such as pelvic adhesions, endometriosis, sequelae of pelvic inflammatory disease, leiomyoma and pelvic varices. METHODS: Retrospective case-control study conducted on 199 patients consecutively admitted from January 1998 to January 2000, 116 of them submitted to laparoscopy for the diagnosis of chronic pelvic pain and 83 asymptomatic patients submitted to tubal ligation by laparoscopy. A logistic regression analysis was used to verify the association between chronic pelvic pain and the history of previous cesarean section. RESULTS: In women with chronic pelvic pain, a history of cesarean section was observed in 67.2% of cases, adhesions in 51.7%, endometriosis in 33.6%, sequelae of pelvic inflammatory disease in 31.9%, leiomyoma in 6.9% and pelvic varices in 11.2%. In asymptomatic women, a history of cesarean section was observed in 38.5%, adhesions in 24.1%, endometriosis in 9.6%, sequelae of pelvic inflammatory disease in 4.8%, leiomyoma in 7.2% and pelvic varices in 3.6%. In a logistic model, chronic pelvic pain was associated with a history of cesarean section (O.R.=3.7), as well as with endometriosis (O.R.=8.5), sequelae of pelvic inflammatory disease (O.R.=10.5). CONCLUSIONS: In the present study cesarean section was associated with chronic pelvic pain. This fact may be the cause of a public health problem in the coming years, due to the raised rates of cesarean section in Brazilian women.
