RESUMO

The objective of this study was to investigate proliferation, apoptosis, and antiapoptotic molecule expression in endometrial cells of reproductive-aged women with and without type II diabetes mellitus (T2D). In this case-control study, a total of 80 endometrial tissue specimens from reproductive-aged women (35 in the proliferative phase and 45 in the secretory phase) were examined. The age and body mass index (BMI) were matched between the groups. Formalin-fixed and paraffin-embedded endometrial tissue samples were used for immunohistochemistry analysis. The presence of proliferation was evaluated with Ki-67 expression, antiapoptotic function of cells was evaluated with Bcl-2 expression, and apoptosis was evaluated with terminal deoxynucleotidyl transferase (TUNEL) immunoreactivity in both the glandular epithelium and stroma of endometrial tissue samples from women with and without T2D. Ki-67 expression in the glandular epithelium and Bcl-2 expression in both the glandular epithelium and stroma were significantly higher in endometrial tissue samples of women in the T2D group than the control group (p = 0.0008, p = 0.0022, and p = 0.0261, respectively). TUNEL immunoreactivity was significantly lower in the glandular epithelium of women in the T2D group than the control group (p = 0.0001). Glandular Ki-67 expression correlated positively with BMI, use of insulin, and hemoglobin A1c level (p = 0.0034, p = 0.0154, and p = 0.0011, respectively). Glandular Bcl-2 expression correlated positively with BMI and duration of T2D (p = 0.0090 and p = 0.0109, respectively). Stromal Bcl-2 expression correlated positively with duration of T2D (p = 0.0069). TUNEL immunoreactivity in the glandular epithelium correlated negatively with duration of T2D (p = 0.0340) and positively with the use of oral antidiabetic agents (p = 0.0226). Compared to age and BMI-matched controls, women with T2D experienced increased cell proliferation and decreased apoptosis in the glandular epithelium and increased antiapoptotic function in both the glandular epithelium and stromal cells. High BMI values in women with diabetes seemed to contribute to increased cell proliferation and increased antiapoptotic function in the glandular epithelium but not the stromal cells.

RESUMO

The chronic course of endometriosis suggests that the immune system may play a role in its aetiology. There may be resistance to cell lysis, as well as an immune defect underlying endometriosis. Granzyme B is a serine protease that is secreted by Natural Killer (NK) cells and cytotoxic T lymphocytes during a cellular immune response and can induce apoptosis. The aim of this study was to evaluate the relationship between both Granzyme B levels and Granzyme B gene polymorphisms in endometriosis patients. Women between the ages of 20 - 45 were included in the study. The patients were divided into two groups: those diagnosed with endometriosis and those who had not been diagnosed with endometriosis. In the blood samples, Granzyme B gene polymorphisms and serum levels of Granzyme B were studied. There was no difference between the groups in terms of median Granzyme B levels and the presence of AA, AG, and GG genotypes. There was a difference in median granzyme levels for the control group; the GG genotype was found at a lower frequency. The immune defect within endometriosis-related immune cells may not be exclusively due to Granzyme B. Other mediators that are secreted from immune cells may have additive effects.IMPACT STATEMENTWhat is already known on this subject? NK cells are cytotoxic and inhibit the implantation of autologous endometrial cells that are spilled into the peritoneum by retrograde menstruation. Thus, a reduction in NK cell activity may facilitate the progression of endometriosis. The literature review reveals that there are studies suggesting that NK cell activity may be insufficient in endometriosis. Granzyme B is a serine protease that is secreted by NK cells and cytotoxic T lymphocytes during a cellular immune response.What do the results of this study add? Granzyme B is one of the cytotoxic granules in NK and cytotoxic T lymphocyte cells and its genetic polymorphisms were tested in endometriosis. We found that median Granzyme B levels were significantly different in patients with the GG genotype in the control group, compared to those with the AA and AG genotype. However, this difference was not detected between the control and endometriosis groups.What are the implications of these findings for clinical practice and/or further research? Our results contribute to uncovering the pathogenesis of endometriosis since there are no previous studies in the literature regarding this topic. Although we did not find a difference, our results will inform further studies made on this topic. Studies with different molecules and an increased number of patients are needed. The immune defect of endometriosis may not be due exclusively to Granzyme B. Other mediators that are secreted from immune cells may have mutual effects and interactions.

RESUMO

BACKGROUND: Endometriosis is an estrogen-dependent inflammatory disease that often causes infertility and chronic pelvic pain. Although endometriosis is known as a benign disease, it has demonstrated characteristics of malignant neoplasms, including neoangiogenesis, tissue invasion, and cell implantation to distant organs. Octamer-binding protein 4 (Oct-4) is a molecular marker for stem cells that plays an essential role in maintaining pluripotency and self-renewal processes in various types of benign and malignant tissues. CD44 is a multifunctional cell surface adhesion molecule that acts as an integral cell membrane protein and plays a role in cell-cell and cell-matrix interactions. E-cadherin is an epithelial cell-cell adhesion molecule that plays important role in the modulation of cell polarization, cell migration, and cancer metastasis. The aim of this study was to investigate the expression patterns of Oct-4, CD44, and E-cadherin in eutopic and ectopic endometrial tissues from women with endometrioma compared to control endometrial tissues from women without endometrioma. METHODS: In the present study, Oct-4, CD44, and E-cadherin expressions were evaluated in eutopic and ectopic endometrial tissue samples from women with endometrioma (n = 32) and compared with those of control endometrial tissue samples from women without endometrioma (n = 30). RESULTS: Immunohistochemical expression of Oct-4 was significantly higher in the ectopic endometrial tissue samples of women with endometrioma than in the control endometrial tissue samples (p = 0.0002). Conversely, CD44 and E-cadherin expressions were significantly lower in the ectopic endometrial tissue samples of women with endometrioma than in the control endometrial tissue samples (p = 0.0137 and p = 0.0060, respectively). Correlation analysis demonstrated significant correlations between Oct-4 expression and endometrioma cyst diameter (p = 0.0162), rASRM stage (p = 0.0343), and total rASRM score (p = 0.0223). Moreover, CD44 expression was negatively correlated with the presence of peritoneal endometriotic lesions (p = 0.0304) while E-cadherin expression was negatively correlated with the presence of deep infiltrating endometriosis (p = 0.0445). CONCLUSIONS: Increased expression of Oct-4 and decreased expression of adhesion molecules in endometriotic tissues may contribute to the development and progression of endometriosis.

RESUMO

BACKROUND: HPV causes specific cell-mediated immunity in the cervix. Mononuclear cells such as helper T cells (CD4+), cytotoxic T cells (CD8+), and dendritic cells play a critical role in the initiation of the HPV-specific immune response and destruction of virus-infected cervical epithelial cells. The programmed cell death ligand 1 (PD-L1) gene encodes an immune inhibitory receptor ligand and overexpression of PD-L1 inhibits T-cell activation and cytokine production. The aim of this study was to investigate the expression of PD-L1 in cervical tissue and its correlation with clinicopathological findings. METHODS: In this cross-sectional study, a total of 94 women who were referred for colposcopy due to abnormal Papanicolaou (PAP) test results and/or HPV positivity were evaluated. The presence of HR-HPV-DNA was analyzed using type- and gene-specific primers along with commercial real-time polymerase chain reaction. The cervical examination was done with a colposcope. Cervical biopsies were obtained from the areas that were evaluated as abnormal during the colposcopy. Histopathological result of cervical biopsies were defined as no intraepithelial neoplasia (CIN 0), mild CIN (CIN I), and moderate-to-high CIN (CIN II-III). All women were classified into four groups based on their HR-HPV positivity and cervical biopsy results: Group I (controls; n = 29), HR-HPV (-) CIN 0; Group II (n = 21), HR-HPV (+) CIN 0; Group III (n = 20), HR-HPV (+) CIN I; and Group IV (n = 24), HR-HPV (+) CIN II-III. A semi-quantitative scoring system was used to evaluate the degree of Ki-67, p16, and PD-L1 immunoreactivity in the cervical tissue samples. RESULTS: We found that PD-L1 expression in both mononuclear cells and in cervical epithelial cells gradually increases from the HR-HPV (-), CIN 0 group to the HR-HPV (+), CIN II-III group (p = 0.0003 and p = 0.0394, respectively) and mononuclear PD-L1 expression was correlated with HPV type, initial Pap test results, HPV persistence, and CIN persistence or recurrence (p = 0.0180, p = 0.0109, p = 0.0042, and p = 0.0189, respectively). Moreover, mononuclear PD-L1 expression was also correlated with Ki-67 and p16 immunoreactivity (p = 0.0432 and p = 0.0166, respectively). Epithelial PD-L1 expression was only correlated with HPV type and the presence of HPV persistence (p = 0.0122 and p = 0.0292, respectively). CONCLUSION: During the initial evaluation of the cervical histology results, the assessment of PD-L1 expression-especially in mononuclear cells in cervical tissue samples-may provide more information on the progression of HR-HPV infection and its persistence.

RESUMO

Endometriosis is an estrogen-dependent inflammatory disease that causes infertility and chronic pelvic pain. Ovarian endometrioma is the most common form of endometriosis, and conservative surgery is the main preferred therapeutic approach for endometrioma-associated symptoms. The aim of this study was to investigate the persistence of cyclic and noncyclic pelvic pain (NCPP) after endometrioma excision and their relationship to clinical and histopathological findings. In this prospective observational study, 41 symptomatic patients were evaluated for the presence of pain symptoms 3 to 6 months after endometrioma excision. Tissue specimens of endometrioma were collected during the operation and embedded in paraffin. The persistence of pain was 41.4%. Surgical excision of endometrioma significantly decreased NCPP and dysmenorrhea, but not dyspareunia ( P < .0001, P = .0001, and P = .25, respectively). Histopathological changes, including depth of endometriosis penetration into the cyst wall, the presence of macrophage infiltration, and vascularity of endometrioma cyst walls were significantly higher in patients with pain persistence than in patients without pain persistence ( P = .0034, P = .0042, and P = .0007, respectively). Moreover, proliferating cell nuclear antigen (PCNA) and CD34 immunoreactivity in both glandular and stromal cells and vascular endothelium were significantly higher in patients with pain persistence ( P = .0079 and P = .0025, respectively). Additionally, these histopathological changes and PCNA and CD34 immunoreactivity were significantly correlated with the persistence of NCPP and dysmenorrhea. The discovered differences in patients with endometrioma with or without pain persistence may indicate a possible relationship between endometrioma-associated pain and histopathological variability of endometrioma.

RESUMO

BACKGROUND: Women with polycystic ovary syndrome are more likely to suffer from obesity, insulin resistance, and chronic low-grade inflammation. In fact, the excessive activation of monocytes exacerbates oxidative stress and inflammation. However, high-density lipoprotein cholesterol neutralizes the pro-inflammatory and pro-oxidant effects of monocytes. The aim of this study is to investigate whether monocyte counts to high-density lipoprotein cholesterol ratio can predict the inflammatory condition in patients with polycystic ovary syndrome. METHODS: In this cross-sectional study, a total of 124 women (61 of them with polycystic ovary syndrome and 63 age-matched healthy volunteers) were included in the study population. Obese polycystic ovary syndrome patients (n = 30) with a body mass index of ≥25 kg/m2 and lean polycystic ovary syndrome patients (n = 31) with a body mass index of < 25 kg/m2 were compared to age-and body mass index-matched healthy subjects (30 obese and 33 non-obese). RESULTS: The monocyte counts to high density lipoprotein cholesterol values in women with polycystic ovary syndrome were significantly higher than in control subjects (p = 0.0018). Moreover, a regression analysis revealed that body mass index, the homeostasis model assessment of insulin resistance and the high sensitivity C-reactive protein levels were confounding factors that affected the monocyte counts to high density lipoprotein cholesterol values. Additionally, a univariate and multivariate logistic regression analysis demonstrated that the increased monocyte counts to high density lipoprotein cholesterol values were more sensitive than the other known risk factors (such as increased body mass index, homeostasis model assessment of insulin resistance and high sensitive C-reactive protein levels) in the prediction of the inflammation in patients with polycystic ovary syndrome. CONCLUSION: The present study demonstrated that the monocyte count to high density lipoprotein cholesterol may be a novel and useful predictor of the presence of polycystic ovary syndrome.

RESUMO

Endometriosis is defined as the presence of functional endometrial tissues outside of the uterine cavity. Ovarian endometrioma is the most common type of endometriosis. It is an estrogen-dependent inflammatory disease that frequently causes infertility and chronic pelvic pain. Cyclophilin A (CyPA) is secreted from various types of cells in response to inflammatory stimuli. Many previous studies have shown that the increased expression and/or heightened plasma levels of CyPA exacerbates inflammation. The aim of this study is to evaluate CyPA immunoreactivity in ovarian endometrioma cyst wall. In this cross-sectional study, CyPA immunoreactivity in endometrial tissue samples obtained from uterine cavity and in endometrioma cyst walls of 44 consecutive women with ovarian endometrioma were compared with control endometrial tissue samples obtained from uterine cavity of 40 women without endometrioma. All endometrioma samples were confirmed via histopathological examination. Finally, the relationship between CyPA immunoreactivity and the clinicopathological findings related to endometrioma were evaluated. The CyPA expression rates in glandular cells, stromal cells, and the capillary endothelium were significantly higher in endometrioma cyst walls of women with ovarian endometrioma than in the control endometrial tissue of women without endometrioma (p = 0.0002, p = 0.0417 and p = 0.0067, respectively). The correlation analysis demonstrated that glandular CyPA expression was correlated with endometrioma recurrence (p = 0.0267). However, stromal and vascular endothelial CyPA expression were correlated with dysmenorrhea recurrence (p = 0.0023 and p = 0.0003, respectively). In conclusion, the increased expression of CyPA in ectopic endometrial tissue is associated with endometrioma recurrences and vascularity.

RESUMO

Osteogenesis imperfecta is a clinically heterogenous disease caused by defective collagen syntesis associated with a mutation in the COL1A1 or COL1A2 genes. In this report, we present a case of osteogenesis imperfecta (OI) type IV, seen in a female fetus with incurved femurs at 18 weeks of gestation. Molecular analysis of the newborn revealed a novel mutation at position c.560 (c.560 G > T) of the exon 12 in the COL1A2 gene; which lead to the glycine modification with valine (p.Gly187Val) at codon 187. The pregnancy follow-up was uneventful. After delivery, the newborn underwent biphosponat therapy and no fracture was detected until 1 year old.

RESUMO

Nesfatin-1, encoded by the nucleobindin-2 (NUCB2) gene, is an anorexigenic protein related to energy metabolism, obesity, and insulin resistance. The aim of this study was to evaluate NUCB2 gene polymorphism (rs757081) and its association with serum levels of nesfatin-1 in obese and non-obese women with polycystic ovary syndrome (PCOS). In the study population, we analyzed 60 patients with PCOS and 26 age-matched healthy women as controls. The patients with PCOS were divided into two groups based on body mass index (BMI): obese group (n = 28) or non-obese group (n = 32). NUCB2 was genotyped using the polymerase chain reaction-restriction (PCR) technique. Serum nesfatin-1 level was measured by enzyme-linked immunosorbent assay (ELISA). Nesfatin-1 levels in the obese PCOS group were significantly lower than those in the non-obese PCOS and control groups (p < 0.001). There was no statistically significant difference in the distribution of NUCB2 genotypes among the groups (p > 0.05), whereas nesfatin-1 levels in the CC and CG genotypes were lower than those in the GG genotype. Nesfatin-1 decreases in PCOS, especially in obese women, and is negatively correlated with cardiometabolic risk factors. Although genotype disturbances of NUCB2 were similar among the groups, CC and CG genotypes accompanied lower nesfatin-1 levels. C allele of NUCB2 gene polymorphism and nesfatin-1 may play a role in the pathophysiology of PCOS.

RESUMO

The aim of the study is to investigate the effects of the interleukin-6 (IL-6) blocker tocilizumab in a hyperstimulated rat model and compare it with ranibizumab, a gonadotropin-releasing hormone antagonist (GnRHA), and cabergoline. Forty-seven rats were randomly divided into the following seven groups: Group 1: OHS; Group 2: OHS+ GnRHA; Group 3: OHS + ranibizumab; Group 4: OHS + cabergoline; Group 5: OHS + low-dose tocilizumab (TL); Group 6: OHS + high-dose tocilizumab (TH); Group 7: sham. Ovarian weight was significantly lower only in the ranibizumab group than in the OHS group. Estrogen levels were significantly lower in the GnRHA group than in the OHS and the treatment groups. Progesterone levels were significantly lower in the ranibizumab, cabergoline, and TL groups than in the OHS group. Among the treatment groups, corpus luteum counts were lower than in the OHS group. Corpus luteum counts were lowest in the tocilizumab groups. IL-6 intensity was lower in all treatment groups than in the OHS group. In the ranibizumab group IL-6 intensity was the lowest. The TL group did not significantly differ from the GnRHA and cabergoline groups regarding IL-6 expression. Ovarian VEGF expression was significantly lower in all treatment groups. For the TL, ranibizumab, and cabergoline groups VEGF intensity was similar. Tocilizumab may be a new strategy for preventing ovarian hyperstimulation syndrome by inhibition of IL-6.

RESUMO

INTRODUCTION: Accessory Spleen (AS) is a very rare entity and usually near the spleen's hilum and in the tail of the pancreas. Pelvis reported as an atypical and a rare localization. AS may be formed during embryonic life, they rise from the left side of the dorsal mesogastrium as a result of imperfect fusion of separate splenic masses. PRESENTATION OF CASE: We report a case of an AS presenting as an left adnexal mass in a middle-aged woman. Transvaginal ultrasonography and magnetic resonance imaging (MRI) revealed a left adnexial mass. Laparatomy was performed, and histological examination revealed that resected mass was splenic tissue. DISCUSSION: An AS is an incidental finding of no clinical significance in most patients. AS are generally determined during radiological investigations or during open or laparoscopic surgeries. When, the AS settle in the adnexal area; the differential diagnosis could include the causes of adnexal masses like enlarged lymph nodes, subserous fibroid, ovarian tumors, organized hematoma, tuboovarian abscess. CONCLUSION: Althought pelvic accessory spleen is a rare condition, should be considered in the differential diagnosis of adnexal masses.

RESUMO

OBJECTIVE: Polycystic ovary syndrome (PCOS) is one of the most common endocrinopathies, affecting 5-8% of reproductive-age women. It is associated with insulin resistance, central obesity, type 2 diabetes mellitus, dyslipidemia, and cardiovascular diseases. The current study was undertaken to evaluate serum copeptin and obestatin levels, carotid artery intima-media thickness, and brachial artery flow mediated dilatation in obese and nonobese women with PCOS and age-matched healthy controls and to investigate their relationship with each other and with clinical, metabolic, and hormonal parameters and cardiovascular risk factors. METHOD: In the study population, we analyzed 60 patients with PCOS and 30 age-matched healthy women as controls. The patients with PCOS were divided into two groups based on body mass index (BMI): obese group (BMI>30kg/m(2), n=30) or nonobese group (BMI<30kg/m(2), n=30). History was obtained and a physical examination, peripheral venous blood sampling, and carotid and brachial artery ultrasonography were performed. Serum copeptin and obestatin levels, total testosterone, C-reactive protein (CRP), glucose, total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, triglycerides, homeostasis model assessment for insulin resistance (HOMA-IR), carotid artery intima-media thickness (CIMT), and brachial artery flow-mediated vasodilation (FMD) were determined and compared among the groups. RESULTS: Women with PCOS, especially obese ones, had higher triglycerides, HOMA-IR, total testosterone, CRP, systolic and diastolic blood pressure, and waist-to-hip ratio (WHR), and lower HDL. Serum obestatin levels were significantly lower in the obese PCOS group than they were in the nonobese and control groups (p<0.001). Serum copeptin levels were significantly higher in the obese PCOS group than they were in the nonobese PCOS and control groups (p<0.001). CIMT values were similar among the groups (p>0.05). Brachial artery FMD was lower in the PCOS groups than it was in the control group (p<0.001). Obestatin and FMD values were negatively correlated with cardiovascular risk factors, whereas copeptin was positively correlated. A significant positive correlation was found between copeptin, BMI, WHR, hirsutism score, total testosterone, and HOMA-IR. There was no correlation between CIMT, copeptin, obestatin, and FMD. A positive correlation was seen between CIMT, BMI, triglycerides, and HOMA-IR. CONCLUSION: Copeptin and obestatin may provide useful information regarding future cardiovascular risk in PCOS patients as copeptin was positively correlated and obestatin was negatively correlated with cardiovascular risk factors.

RESUMO

The aim of this study is to evaluate the effects of sildenafil citrate on cisplatin-induced ovarian toxicity. Thirty-two female rats were divided into four groups. Group 1: saline control; group 2: cisplatin; group 3: sildenafil citrate; and group 4: cisplatin plus sildenafil citrate group. In groups 2 and 4, the rats were injected with 5 mg/kg cisplatin intraperitoneally (i.p.). In groups 3 and 4, the rats were injected with 1.4 mg/kg sildenafil citrate i.p. The ovaries were removed two weeks later in all groups. Histopathologic examination, follicle counting and classification were performed. The expression of anti-Müllerian hormone (AMH) was detected immunohistochemically in the ovarian tissues. Sildenafil alleviated cisplatin-induced histopathological changes in the ovarian tissue. Primordial, secondary and tertiary follicles were diminished in group 2 compared with group 1 (p < 0.05). Pretreatment with sildenafil citrate preserved primordial follicle count in group 4 compared with group 2, and the difference was statistically significant (p < 0.05). According to our results, immunoreactivity intensity of AMH was lower in group 2 compared with group 1 (92.4 ± 3.97 versus 88.8 ± 1.77) but not significantly, whereas immunoreactivity intensity of AMH was higher in group 4 compared with group 2 (88.8 ± 1.77 versus 94.1 ± 2.36; p < 0.05). Our results demonstrated that pretreatment with sildenafil citrate is beneficial for protecting the ovaries from cisplatin-induced damage. Sildenafil citrate can be a choice for fertility preservation.

RESUMO

AIMS: To evaluate the role of metastin levels in the pathophysiology of pre-eclampsia and to determine whether there is a relationship between the severity of the disease and Doppler velocimetry measurements. METHODS: This cross-sectional study included 89 pregnant women (50 healthy normotensive pregnant women, 15 patients with mild pre-eclampsia, and 24 patients with severe pre-eclampsia) at the third trimester of pregnancy. The maternal levels of plasma metastin were determined by enzyme-linked immunosorbent assay. The umbilical artery and uterine artery blood flow velocities were measured by transabdominal color and pulsed Doppler ultrasound. RESULTS: Plasma metastin levels were lower in patients with pre-eclampsia than those in the normotensive pregnant women. Four patients with mild pre-eclampsia and seven patients with severe pre-eclampsia had abnormal Doppler velocimetry findings. Metastin levels of pre-eclamptic patients with abnormal Doppler velocimetry findings were significantly lower than those in patients with normal Doppler velocimetry findings. Plasma metastin levels negatively correlated with proteinuria in 24 hours and with mean arterial pressure in the cases of pre-eclampsia. CONCLUSIONS: The findings suggest that decreased maternal concentrations of plasma metastin may be involved in the pathogenesis of pre-eclampsia. Plasma metastin levels may be useful in the assessment of the severity of pre-eclampsia. However, further trials are needed to clarify the role of metastin in pre-eclampsia.

RESUMO

OBJECTIVE: To evaluate retinol-binding protein 4 (RBP4), leptin, and asymmetric dimethylarginine (ADMA) levels in young women with polycystic ovary syndrome (PCOS) and to investigate their relationship with each other and with clinical, metabolic, and hormonal parameters. DESIGN: Clinical study. SETTING: University hospital. PATIENT(S): Fifty-seven young women with PCOS (obese [n = 27] and nonobese [n = 30]) and 27 age-matched healthy controls. INTERVENTION(S): History and physical examination, peripheral venous blood sampling. MAIN OUTCOME MEASURE(S): Asymmetric dimethylarginine, RBP4, leptin, LH, FSH, DHEAS, total T, E(2), total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, triglyceride (TG), and homeostasis model assessment insulin resistance index (HOMA-IR). RESULT(S): Obese women with PCOS had significantly higher HOMA-IR, DHEAS, leptin, RBP4, and ADMA levels. Leptin levels were significantly increased in nonobese subjects with PCOS. Leptin and ADMA levels were positively correlated with HOMA-IR in PCOS. There was no correlation between RBP4 and HOMA-IR. Leptin, RBP4, and ADMA levels are positively correlated in PCOS. CONCLUSION(S): [1] Young obese women with PCOS have increased ADMA, RBP4, and leptin levels, and they are positively correlated with each other. [2] The increased levels of leptin are independent of obesity, and leptin seems to have an association with IR. [3] Levels of RBP4 may not reflect IR in PCOS.

RESUMO

OBJECTIVE: To compare lipocalin-2 (LCN2) levels in pre-eclamptic women with those in healthy pregnant women, and to determine whether there is a correlation between LCN2 levels and the severity of the disease. METHODS: The study included 66 pregnant women: 22 healthy pregnant women (Group 1), 23 women with mild pre-eclampsia (Group 2), and 21 women with severe pre-eclampsia (Group 3). Pre-eclamptic women and normal controls were carefully matched for maternal age, gestational age, and body mass index (BMI). The maternal levels of plasma LCN2 were determined by enzyme-linked immunosorbent assay. RESULTS: Plasma LCN2 levels in the pre-eclamptic group were significantly lower than those in the healthy control group (p < 0.05). Although plasma LCN2 level was lower in the severe compared to the mild pre-eclamptic group, the difference was not statistically significant (p > 0.05). There was no significant correlation between LCN2 levels and the homeostasis model assessment of insulin resistance (HOMA-IR), BMI, triglyceride, gestational week at delivery, birth weight, and systolic and diastolic blood pressure in pre-eclamptic and healthy pregnant women (p > 0.05). CONCLUSIONS: Our results show that there are decreased concentrations of plasma LCN2 in pre-eclamptic subjects and this may indicate that LCN2 plays a role in the pathogenesis of pre-eclampsia. However, further experiments are needed to clarify this role.

RESUMO

Cranial diabetes insipidus (DI) due to postpartum haemorrhage is an extremely rare clinical event. We describe herein isolated posterior pituitary insufficiency in a 26-year-old woman who had undergone subtotal hysterectomy for severe postpartum haemorrhage because of uterine rupture. The patient experienced polyuria within 6 h postoperatively. DI was suggested by the elevated urine volumes and low urine specific gravity. The diagnosis of DI was confirmed by water deprivation test and vasopressin stimulation test. The anterior pituitary function was within normal limits. A high clinical suspicion is certainly required for the diagnosis of DI in the immediate postpartum period. To rapidly initiate appropriate therapy, the possibility of DI should always be kept in mind while evaluating patients who have polyuria and polydipsia after severe postpartum bleeding. Delay or failure to treat this condition might result in hypovolemic shock.

RESUMO

Background. Intraabdominal lesions such as mesenteric cysts are uncommon disorders. Most are discovered incidentally during routine abdominal examinations. Methods. We report a patient with a mesenteric cyst masquerading as tuberculous peritonitis and ascites. Conclusion. Mesenteric cysts generally do not show typical clinical findings. They may also present with peritoneal tuberculosis findings such as low albumin gradient ascites with high ascitic adenosine deaminase levels. Surgery is used to remove a wide variety of mesenteric cysts. A correct diagnosis can be made by the combined use of radiographic and sonographic examinations in conjunction with the clinical signs.

RESUMO

Conjoined twins are an extremely rare congenital malformation without any known genetic predisposition. Omphalopagus twins are the second most common variety of conjoined twins and usually are joined at the umbilicus. We present omphalopagus conjoined twins demonstrated with true FISP (fast imaging with steady-state procession) and HASTE (half- Fourier acquisition single-shot turbo spin-echo) magnetic resonance imaging (MRI) sequences, which showed Dandy- Walker malformation in one of the pair. To our knowledge, this is the first case of conjoined twins with this malformation, which was diagnosed with ultrafast MRI.

RESUMO

PURPOSE: The purpose of this study was to evaluate the short-term efficacy and complication rates of posterior intravaginal slingplasty (IVS) procedures. METHODS: Thirty-four patients who had advanced (grade 4) uterine prolapse were recruited. All patients underwent vaginal hysterectomy and the cuff was suspended with a posterior IVS operation. The mean follow-up duration was 12 months (range 3-20 months). RESULTS: Thirty-three patients (97.1%) had satisfactory level I support defined objectively as stage 0 or I for point C as described in the pelvic organ prolapse quantification system. There were no rectal, vesical, ureteric, or vascular injuries in this series. During the postoperative period no complications, including tape erosion, were seen. CONCLUSIONS: Posterior IVS is a minimally invasive procedure for grade 4 genital prolapse with a high success rate.
