ABSTRACT

BACKGROUND: Immune responses have long been an area of interest in cancer research. In this study, the effects of programmed cell death-1 (PD-1) and its ligand (PD-L2) on the prognosis of colorectal cancer (CRC) were investigated. METHODS: Primary tumour specimens of stage III CRC patients operated between 2002 and 2013 were assessed for PD-1 and PD-L2 expression and various clinicopathological and prognostic factors. RESULTS: We observed a significant relationship between poor prognostic factors and PD-1/PD-L2 expression. These biomarkers were also found to serve as independent risk factors for LIR and MSI. In univariate analysis, relapse-free survival (RFS) and overall survival (OS) rates were found to be poor in PD-1 and PD-L2 positive patients. In multivariate analysis, these biomarkers were found to serve as independent poor prognostic factors for RFS and OS. CONCLUSIONS: Our data indicate that PD-1 and PD-L2 may serve as independent prognostic survival parameters for CRC patients and may be employed for the design of targeted therapies.

ABSTRACT

AIM: This study aims to assess the educational needs of family practitioners and evaluate the efficacy of the ongoing "Maternal Health and Family Planning Distance Education" program conducted by the General Directorate of Health Research (SAGEM) of the Turkish Ministry of Health. METHODS: This study consisted of three phases. In the first phase, an online survey on maternal health and family planning educational needs was sent to 20,611 physicians via e-mail. Of the 20,611 physicians, 4,729 completed the survey. In the second phase, of the 1,061 physicians registered to the education program, 632 physicians with active participation were included. In the third phase, the preeducation expectations of 287 physicians and posteducation satisfaction of 54 physicians were analyzed with a questionnaire. RESULTS: The majority of the physicians were employed in a family health center (97.4%) and practicing for 16-20 years (23.2%) without any prior in-service training (60.9%). High-to-very high educational need was expressed by 56.4% of physicians for pregnancy, delivery, and puerperality. Topics that the physicians, including both those with ≥16 years in practice and without prior in-service training, expressed need for more detailed content were pregnancy, delivery, and puerperality (37.5%); emergency obstetric approach in the primary care setting (33.1%); and gynecological infectious diseases and treatment approach (32.4%). Following the education program, the participants' expectations were fulfilled in terms of refreshing their knowledge, particularly in the field of Maternal Health and Family Planning (87.1% and 75.9%) and the percentage of participants who expressed that they had sufficient high level knowledge increased from 55% to 68.5%. CONCLUSION: The education on Maternal Health and Family Planning refreshed the knowledge of participants and highly met the preeducation expectations. Determining the educational needs and expectations of the target population prior to the education program seems to have an important role on determining its overall success.

ABSTRACT

OBJECTIVE: The aim of this study was to investigate the clinical and laboratory features of patients with the incidental diagnosis of endometrial adenocarcinoma (EC) during infertility work-up, with special attention given to treatment approaches, recurrence rate, and fertility outcome. MATERIAL AND METHODS: The medical records of 577 patients who were diagnosed with EC and treated between 2007 and 2013 were included in the study. Out of 577 EC patients, 5.1% (n = 30) were ≤ 40 years of age. However, 10 patients had a history of infertility and had been diagnosed during evaluation for infertility. Patients' clinical and laboratory data were reviewed retrospectively. RESULTS: The mean age at diagnosis was 34.3 ± 4.5 years and the mean duration of infertility was 5.1 ± 4.7 years. Immediate staging surgery was performed on three patients. The others were treated with oral megestrol acetate and/or a levonorgestrel-containing intrauterine device (IUD) for 6 months. The mean duration of postoperative or postdiagnostic follow-up was 44.7 ± 25.9 months. The disease persistence and recurrence rates were 11.1% and 22.2%, respectively. Two patients achieved pregnancy naturally or by assisted reproductive technology (ART) trial. CONCLUSION: The investigation of patients during infertility work-up provides an opportunity to evaluate the endometrium and its malignancies in young women, when the disease is in its early stage and symptom free. The standard surgical treatment for early-stage EC is total hysterectomy with bilateral salpingo-oophorectomy. However, conservative management of early stage EC with progestational drugs, especially in young patients who wish to preserve their fertility, is acceptable with the possibility of future pregnancies.

ABSTRACT

BACKGROUND: There are limited data in the literature related to concomitant genital or extra-genital organ pathologies in patients with borderline ovarian tumors (BOTs). The aim of this study was to evaluate our experience with 183 patients to draw attention to the accompanying organ pathologies with BOTs. MATERIALS AND METHODS: One hundred eighty-three patients with BOTs, diagnosed and/or treated in our center between January of 2000 and March of 2013 were evaluated retrospectively. Data related to age, tumor histology, lesion side, disease stage, accompanying incidental ipsilateral and/or contralateral ovarian pathologies, treatment approaches, and follow-up periods were investigated. Incidental gynecologic and non-gynecologic concomitant organ pathologies were also recorded. RESULTS: The mean age at diagnosis was 40.6 years (range: 17-78). Ninety- five patients (51%) were ≤40 years. A hundred and forty-seven patients (80%) were at stage IA of the disease. The most common type of BOT was serous in histology. Non-invasive tumor implants were diagnosed in 4% and uterine involvement was found 2% among patients who underwent hysterectomies. There were 12 patients with positive peritoneal washings. Only 17 and 84 patients respectively had concomitant ipsilateral and concomitant contralateral incidental ovarian pathologies. The most common type of uterine, appendicular and omental pathologies were chronic cervicitis, lymphoid hyperplasia and chronic inflammatory reaction. CONCLUSIONS: According to our findings most of accompanying pathologies for BOT are benign in nature. Nevertheless, there were additional malignant diseases necessitating further therapy. We emphasize the importance of the evaluation of all abdominal organs during surgery.

ABSTRACT

BACKGROUND AND OBJECTIVES: Chorioamnionitis (CA) is an acute inflammation of the membranes and chorion of the placenta. The aim of this study was to determine the effect of histological CA on the short-term outcome of preterm infants. SUBJECTS AND METHODS: The clinical characteristics and outcomes of the preterm infant including respiratory distress syndrome, duration of mechanical ventilation, patent ductus arteriosus (PDA) requiring medical treatment or ligation, necrotizing enterocolitis, bronchopulmonary dysplasia, death and intraventricular hemorrhage (IVH; grade III-IV) were analyzed. RESULTS: Two hundred and eighty-one infants born at ≤32 weeks gestational ages were included. Infants were divided into two groups: one with histological CA (n = 145) and without histological CA (n = 136). Mean gestational age was 28.8 ± 2.6 weeks and 29.1 ± 2.5 weeks, and mean birth weight was 1138 ± 350 g and 1210 ± 299 g, respectively. There were no differences in gestational age and birth weight among the groups. Compared with the group, histological CA was associated with early onset sepsis (p = 0.007), PDA (p = 0.003), IVH (p = 0.03), and death (p = 0.04). CONCLUSION: Maternal histological CA is an important risk factor for preterm deliveries and associated with serious morbidities such as early onset sepsis, IVH, PDA and increased mortality.

ABSTRACT

OBJECTIVE: In this study, the Ki-67 proliferative indices among the stages of the endometriosis were compared to clarify whether the proliferation was increased with increasing disease stage. MATERIALS AND METHODS: Thirty-eight patients who underwent surgery either by laparotomy or by laparoscopy with the diagnosis of endometriosis and 21 patients, as controls, who underwent hysterectomy with the diagnosis of myoma uteri and without any endometrial pathology at our hospital between 2005 and 2007 were studied. Biopsy specimens of endometriotic foci and endometriomas in study group, and eutopic endometrium of hysterectomy specimens of control group were studied. RESULTS: Fifty-nine patients were divided into Group 1 (21 patients in control), Group 2 (19 patients in stage I and II of endometriosis), and Group 3 (19 patients in stage III and IV). A moderate correlation between the stage of endometriosis and the degree of Ki-67 staining was found. When Ki-67 immunohistochemical staining was considered according to the threshold value for CA-125 (35 U/mL), Ki-67 positivity was increased with the increase in CA-125 value, but this increase was not statistically significant. CONCLUSION: Endometriosis shows some characteristics of tumors such as high rate of invasion, getting autonomy, and proliferation as the disease progresses with subsequent damage to target organs. When the stage of the disease increases, environment becomes more suitable for increased proliferation and invasion. In this study, the increase in proliferative activity as the severity increases is shown by the increase in Ki-67 index. As more studies are being conducted in this field, pathogenesis will be clarified, which could help in the development of new treatment modalities.

ABSTRACT

BACKGROUND: Large for gestational age (LAG) neonates who had been exposed to an intrauterine environment of either diabetes or maternal obesity are at increased risk of developing the metabolic syndrome. This can be explained by exposure to high glucose and insulin levels in utero which alter fetal adaptation and programming. OBJECTIVES: The aim of the study was to evaluate the onset of preclinical atherosclerosis in utero. METHODS: We measured umbilical artery wall thickness (ruWT) in the third trimester by obstetric ultrasound and umbilical artery intima-media thickness (uIMT) in pathologic specimens of umbilical cords obtained shortly after delivery and investigated the relation between these measurements and serum insulin level and C-peptide level in cord blood and assessed insulin resistance with the homeostasis model assessment of insulin resistance (HOMA-IR) in infants of diabetic mothers (IDMs), i.e. the study group, which was divided into a large for gestational age group (LGA)-IDM group and an appropriate for gestational age group (AGA)-IDM group and compared with a control group. RESULTS: The LGA-IDM group had significantly higher insulin (p < 0.001), C-peptide (p = 0.018) and HOMA-IR levels (p < 0.001) compared with the AGA-IDM and control groups. The LGA-IDM group had significantly larger ruWT (p = 0.013) and uIMT (p < 0.001) compared with the AGA-IDM and the control groups. The LGA-IDM group had increased uIMT and ruWT that correlated with the severity of maternal hyperglycemia. CONCLUSIONS: Measurement of ruWT in the third trimester is feasible, reproducible and strongly correlated with pathological serum insulin, C-peptide in cord blood and HOMA-IR levels.

ABSTRACT

OBJECTIVE: To analyze the relationship of obstetric complications and neonatal outcomes with the thrombophilic status of the mother-infant couples in case of demonstrated placental villous thrombosis in histopathological evaluation after delivery. METHODS: Placentas of high-risk pregnancies, unexplained fetal loss or infants who needed neonatal intensive care unit (NICU) admission were collected at the time of delivery. RESULTS: In a 6 months period, placental villous thrombosis was detected in 30 among 800 placentas. Half of the mothers had a bad obstetric outcome previously, such as at least one abortus or stillbirth. Eighteen neonates (60%) were premature. Seventy-five percent of the neonates (n = 24) needed NICU admission and the mortality rate was 9.3 %. Five of the patients had congenital anomalies. Thrombophilic mutations could be evaluated in seven mothers-infant couples, all of whom had at least one positive mutation for thrombosis. CONCLUSIONS: Severe fetal vasculopathy appears to be a predisposing factor for adverse neonatal outcomes. Analyzing placentas will yield advantages as the same pathological process may repeat in subsequent pregnancies. Thrombophilic mutations should be evaluated to provide the etiology of the adverse outcome and to give prophylaxis for the future pregnancies.

ABSTRACT

Listeria monocytogenes, although an uncommon cause of illness in the general population, is an important pathogen in pregnants, neonates, elderly and immunocompromised patients. Neonatal listeriosis is classified as early (< 5 days) and late (? 5 days) according to the onset of the symptoms and findings of the infection. The most encountered serotypes in early neonatal listeriosis are 1a and 1b, while serotype 4a is more prevalent in the late form. In this report, a neonatal L.monocytogenes meningitis case developed in a female infant born after 36 weeks of gestation from a 29 years old mother, was presented. The newborn was hospitalized in intensive care unit because of low birth weight (1740 g) and prematurity. Due to the worsening of her general condition (feedings difficulty, tachypnea, high fever and bulging fontanel) on the 11th day, blood and cerebrospinal fluid (CSF) cultures were done. CSF culture yielded catalase positive, oxidase negative, gram-positive bacilli on the 4th day of cultivation. The isolate was identified as Listeria monocytogenes and found susceptible to all tested antibiotics (erythromycin, gentamicin, penicillin, trimethoprim sulphamethoxazole, vancomycin, teicoplanin) by automated identification and antibiogram system (VITEC 2, bioMérieux, France). The empirical treatment initiated with vancomycin and meropenem was changed to ampicillin and gentamicin and clinical and microbiological response was obtained. The isolate was serotyped as type 1/2b. No data related to maternal infection or environmental contamination were obtained from the studies investigating the origin of infection. There have been no reported cases of neonatal Listeria meningitis from Turkey in the avaliable literature. This was the first case of neonatal Listeria meningitis in our country and it was presented to withdraw attention to L.monocytogenes serotype 1/2b which was a rare cause of late onset neonatal listeriosis.

ABSTRACT

OBJECTIVE: To determine the efficacy of anti-tumor necrosis factor therapy (etanercept) for treating endometriosis in the rat endometriosis model. STUDY DESIGN: A randomized, placebo-controlled, blinded study using rat endometriosis model. After the peritoneal implantation of endometrial tissue, twenty-eight Wistar female rats were randomized to two equal intervention groups: the control group and the etanercept-treated group. After measuring implant volume, pretreatment blood and peritoneal fluid samples were obtained. A vehicle treatment of 2 mL saline to the rats in control group and 0. 4 mg/kg etanercept SC once weekly were administered in the etanercept-treated group. After four weeks treatment period, the volumes and histopathological properties of the implants were evaluated. A scoring system was used to evaluate preservation of epithelia. Endometrial explants were evaluated immunohistochemically for tumor necrosis factor receptor type 2 (TNFR2). A scoring system was used to evaluate expression grade of TNFR2. RESULTS: There was not a significant difference in spherical volume between control (131.0 (60.3-501.2)) and treatment groups (72.8 (31.2-149.6)) (p>0.025). There was a significant change in between the volumes of implants before and after treatment in etanercept group (p<0.05). At the end of the treatment significant differences among the groups were found in histopathological and immunohistochemical parameters (p<0.05) also histologic scores and HSCORES were decreased in the treatment group significantly (p<0.05). CONCLUSION: These results indicate that etanercept was found to effectively reduce the development of endometriosis in this experimental rat model.

ABSTRACT

The effects of maternal influenza on the fetus are not well understood. Viremia is believed to occur infrequently and thus vertical transmission appears to be rare. Highly pathogenic strains of influenza virus, such as avian influenza A (H5N1), are more likely to be transmitted across the placenta. Placental tissues of seven women with confirmed H1N1 infection were examined molecularly with RT-PCR and microscopically to investigate whether H1N1 virus vertically transmitted. We found no evidence for placental transmission of H1N1 virus in this study. In the absence of vertical transmission, adverse effects like neonatal seizures, encephalopathy, cerebral palsy, and even neonatal death can still occur. Since a significant knowledge gap exists for the effects of this novel virus on the fetus, further studies will be beneficial.

ABSTRACT

OBJECTIVE: This study aims to review cases of extra-ovarian conditions that resembled ovarian malignancy and thus, to evaluate the distribution of primary pathology mimicking ovarian malignancy. METHODS: A retrospective review of women, with final pathology of extra-ovarian diseases mimicking ovarian malignancy, which were managed at Zekai Tahir Burak Women's Health Education and Research Hospital, from January 1995 to April 2010 was undertaken. RESULTS: Among the 2,210 women treated during the study period, extra-ovarian diseases accounted for 5.11% (113/2,210) of all the cases. Of the 113 extra-ovarian diseases, 42 (37.17%) were peritoneal tuberculosis, 25 (22.13%) were gastrointestinal malignancies, 20 (17.70%) were pelvic abscess, 8 (7.08%) were pelvic echinococcosis, 8 (7.08) were schwannoma and other retroperitoneal tumors, 4 (3.53%) were malignant lymphoma, 2 (1.77%) were chronic ectopic pregnancy, gossypiboma, and mesenteric cyst, respectively. CONCLUSION: Medical awareness of infectious diseases such as peritoneal tuberculosis, pelvic abscess, and pelvic echinococcosis in the differential diagnosis of ovarian malignancy is still lacking, especially in developing countries. In addition, in case of a pelvic mass, gastrointestinal and retroperitoneal tumors and malignant lymphoma should always be considered to avoid pitfalls in diagnosis and therapy.

OBJECTIVE: To show the efficacy of anti-tumor necrosis factor therapy (etanercept) for treating endometriosis in an experimental model. DESIGN: A randomized, placebo-controlled, blinded study using rat endometriosis model. SETTING: Experimental research center of Ankara Education and Research Hospital. ANIMAL(S): Twenty-two Wistar female rats. INTERVENTION(S): After peritoneal implantation of endometrial tissue, rats were randomized to two equal intervention groups: control and etanercept-treated groups. After measuring implant volume, blood and peritoneal fluid samples were obtained. Vehicle treatments of 2 mL saline to rats in control and 0.4 mg/kg etanercept SC once weekly were administered in treatment group. Four weeks later, a third laparotomy was performed to remeasure implant volumes, blood, and peritoneal fluid samples. MAIN OUTCOME MEASURE(S): To compare spherical volume, peritoneal fluid and serum levels of VEGF, IL-6, and TNF-α between groups. RESULT(S): There was a significant difference in spherical volume between control [131.0 (60.3-501.2)] and treatment groups [72.8 (31.2-149.6)] (p < 0.025). In etanercept-treated group, a significant difference was found between peritoneal fluid and serum levels of VEGF, IL-6, and TNF-α (p < 0.01). CONCLUSION(S): These results indicate that etanercept was found to effectively reduce the development of endometriosis.

ABSTRACT

OBJECTIVE: Placental factors and hypoxemia are the keys to intrauterine growth restriction (IUGR) and stillbirth. The aim of the study is to analyze histological changes in placentas of IUGR fetuses in pregnancies with no apparent etiologic factor and unexplained intrauterine fetal deaths. MATERIAL AND METHODS: A total of 110 placentas were collected; 26 placentas of IUGR fetuses with no apparent cause, 58 placentas from unexplained intrauterine deaths over 20 weeks of gestation, and 26 placentas from uncomplicated pregnancies who delivered a healthy live baby. Microscopic examinations of placentas were performed for histopathological analyzes. RESULTS: Gestational age at delivery was 33.67±4.37 weeks, 29.15±8.36 weeks, and 39.0±1.52 weeks in women in group I, group II and group III, respectively (p<0.01). Infarction and intervillous thrombosis are significantly more frequent in placentas of Group I and group II. Chronic villitis occurred in 69%, 63% and 30% of group I, group II, and group III, respectively. Placental intravascular thrombi (Group I, 31% and group II, 26%), perivillous fibrin deposition and fibrinoid necrosis (65% in Group I and 53% in group II), infarction, intervillous thrombosis, chronic villitis, hemorrhagic endovasculitis, placental intravascular thrombi, perivillous fibrin deposition, fibrinoid necrosis, erythroblastosis and villous edema were found in the study group. CONCLUSION: The results reported here indicate that a relationship exists between morphological changes in the placentas of IUGR and intrauterine fetal deaths.

ABSTRACT

OBJECTIVE: To evaluate the effects of hysterectomy with ovarian conservation on ovarian histology, and FSH, inhibin A, and inhibin B plasma levels. STUDY DESIGN: Forty-five female Wistar albino rats were used in this study and randomly divided into two groups: hysterectomy (n=30) and sham-operated (n=15). Blood samples were collected before and after (50 and 100 days) abdominal hysterectomy from both groups to measure plasma levels of FSH, inhibin A, and inhibin B. All animals were sacrificed by decapitation to obtain ovaries for histological examination. For statistical analyses, Mann-Whitney U, Chi-square, Wilcoxon matched pairs signed rank sum tests, and two-sided variance analysis were used and statistical significance was defined as p<0.05. RESULTS: There was no difference in hormonal variables between groups when the time interval was considered completely [p>0.05 (for FSH p=0.962; for inhibin A p=0.321; for inhibin B p=0.476)]. In the hysterectomy group, the inhibin B level at postoperative day 50 was significantly lower than the control group (p=0.007) and at postoperative day 100, inhibin A concentrations were increased significantly when compared with the levels at both baseline and postoperative day 50 (p<0.001). Histopathologic evaluation of ovaries 100 days after hysterectomy showed that ovaries from the hysterectomy group had significantly fewer primary (p=0.01), preantral (p<0.001), and antral follicles (p<0.001), and significantly more corpora lutea (p<0.001), atretic (p=0.02), and cystic follicles (p=0.003). CONCLUSION: The results of this experimental rat model suggest that hysterectomy may affect ovarian function.

ABSTRACT

The effect of immunomodulator leflunomide on the development of an experimental endometriosis model was assessed by surgically transplanting autologous fragments of endometrial tissue onto the inner surface of the abdominal wall and arterial cascades of the small intestines. Leflunomide was found to affect the development of endometriosis negatively and seemed to interfere with the growth and maintenance of the uterine explant in this experimental rat model.

ABSTRACT

OBJECTIVE: To test if leflunomide, an immunomodulator, could impede the growth of an ectopic uterine tissue. METHODS: Endometriosis was surgically induced in 26 rats by transplanting an autologous fragment of endometrial tissue onto the inner surface of the abdominal wall. Four weeks later two rats were killed. The volume and weight of the implants were measured. The remaining rats were randomly grouped, and in group 1 no medication was given. To the rats in group 2, 35 mg/kg/d of leflunomide was administered orally. Four weeks later, rats were killed and ectopic uterine tissues were reevaluated morphologically and histologically. A scoring system was used to evaluate preservation of epithelia. RESULTS: Two rats in the control group died 5 weeks after surgery. There was a significant difference in post-treatment spherical volumes (139.1 +/- 92.8 versus 33.5 +/- 12.5 mm3) and explant weights (156.3 +/- 105.6 versus 38.6 +/- 12.6 mg) between the control and leflunomide-treated groups. The epithelia were found to be preserved significantly better in the control group when compared with the leflunomide-treated group (median 2.5 [interquartile range, 1.25] versus median 1.00 [interquartile range, 1.5]). CONCLUSION: Leflunomide appeared to cause regression of experimental endometriosis in rats.

ABSTRACT

The current study was designed to investigate the efficacy of a hyaluronate/carboxymethylcellulose membrane for the prevention of post-operative adhesion in a rat uterine horn model. This is a prospective double-blinded controlled study. Nineteen injured uterine horns were treated with a hyaluronate/carboxymethylcellulose membrane as a barrier and 19 injured uterine horns without any treatment served as a control group. Two weeks later, second look laparotomies were performed in order to assess the degree of the adhesion. Total adhesion scores, histopathological analysis of inflammation process and vascularization of adhesions were compared with control group. P values of 5% or less were considered statistically significant. Animals treated with a hyaluronate/carboxymethylcellulose membrane had significantly reduced post-surgical adhesion scores when compared with control group. In histopathological examination, there was less vascularization in the treatment group. The types and extent of inflammation were similar in two groups. Clinically and histopathologically, a hyaluronate/carboxymethylcellulose membrane is effective in reducing postoperative adhesion formation in the rat uterine horn model.

ABSTRACT

INTRODUCTION: The incidence of genital system hydatid disease in abdominal operation is 0.1%. During a period of 20 years (1957-1977), 12 cases were reported. This disease has no specific symptoms and findings. It is diagnosed intraoperatively. CASE REPORT: We report a 50-year-old patient admitted to our hospital with the complaint of abdominal pain and swelling, operated because of her adnexal mass and diagnosed as primary ovarian hydatid disease (echinococcosis).
