The association of impaired gestational glucose tolerance with maternal and fetal outcomes.

The aim of the present study was to examine the associations of gestational diabetes mellitus (GDM) and impaired glucose tolerance (IGT) with maternal and fetal outcomes.A total of 200 pregnant women were included in this cross-sectional study. A 50-gram oral glucose challenge test (GCT) was performed between 24 and 28 weeks of gestation, followed by glucose tolerance test (OGTT) with 100 grams of oral glucose in those with an abnormal one-hour test result. The following were not significantly different between groups. Preterm labour (PL), pregnancy induced hypertension(PIH), pre-eclampsia, polyhydramnios, and macrosomia. However, a significant increase was noted in the fetal birth weight as well as in number of cesarean deliveries among GDM subjects. Neonatal outcomes were also similar between the two groups. In conclusion, the present results suggest that single high glucose readings in OGTT may be as important as a diagnosis of GDM in terms of fetomaternal complication risk.

The relationship between uterine prolapse and premalignant endometrial pathology.

OBJECTIVE: The aim of this study was to stress the importance of performing a thorough uterine assessment before selecting an organ- sparing surgery in patients presenting with uterine prolapse and no other complaints. MATERIALS AND METHODS: This study included a total of 111 participants who presented with pelvic organ prolapse and underwent hysterectomy for grades 3-4 uterine prolapse. The posthysterectomy histopathology results were classified as benign (atrophic endometrium, proliferative or secretory endometrium) or pathologic (endometrial hyperplasia, endometrial polyp, adenomyosis, myoma uteri, and endometrium carcinoma). RESULTS: Of the 111 patients enrolled in this study, 23 (20.2%) had endometrial hyperplasia, eight (7.2%) had endometrial polyps, 30 (27%) had uterine fibroids, and 20 (18%) had adenomyosis. CONCLUSION: There may be premalignant lesions of the endometrium in both premenopausal and postmenopausal women presenting with uterine prolapse and no other symptoms. A chronic inflammatory process resulting from the extra-vaginal location of the uterus may play a role in the development of these lesions. Further studies are needed on this subject.

Effect of Ramadan fasting on metabolic markers, dietary intake and abdominal fat distribution in pregnancy.

BACKGROUND: The aim of this study is to evaluate the effect of Ramadan intermittent fasting on metabolic markers, dietary intake, anthropometric measurements, and abdominal visceral fat thickness (VFT) in pregnancy. METHODS: Seventy-eight healthy pregnant subjects who had fasted for at least 15 days during the month of Ramadan in 2012 and 2013 and 78 controls were included in this study. Metabolic markers, dietary intake, anthropometric measurements, and ultrasonographic VFT were calculated for each subject before and after Ramadan fasting. RESULTS: When before and after Ramadan values in the fasting group were compared, we found that daily protein intake was increased (p <0.001), but fat and carbohydrate intake remained unchanged. A significant reduction was observed in liquid consumption while the frequency of asymptomatic bacteriuria was increased. High-density lipoprotein significantly increased, and glycated hemoglobin, insulin, and homeostasis model index significantly decreased (p =0.005, p =0.01, p <0.001, and p =0.03, respectively). A significant increase in ferritin was found (p =0.02). No change was observed in subcutaneous fat thickness, while VFT significantly decreased (p =0.08, p =0.005). However, in the control group, only ferritin level increased. CONCLUSION: A combined change in the number and timing of meals and the portioning of the entire daily intake into only two meals per day may have beneficial metabolic effects and reduction in VFT during pregnancy.

Does bupivacaine and fentanyl combination for epidural analgesia shorten the duration of labour?

In this study we aimed to explore the effects of epidural analgesia achieved by a combination of low-dose bupivacaine and fentanyl infused through an epidural catheter on mother, foetus and labour process in nulliparous at-term pregnant women during vaginal delivery. This study was designed in a prospective, randomised controlled manner. Epidural analgesia was achieved in 50 nulliparous women. Fifty nulliparous women did not undergo epidural analgesia procedure. The duration of the first stage of labour was significantly shortened, while the second stage was significantly lengthened in pregnant women who underwent epidural analgesia (p < 0.05). In conclusion, starting epidural analgesia application during the active phase of the first stage of labour may shorten the duration of the first stage compared with the group of nulliparous women not undergoing epidural analgesia. The factor that has an impact on this may be the addition of fentanyl to bupivacaine used for epidural analgesia.

Endometrial pathology in postmenopausal women with no bleeding.

OBJECTIVE: The aim of this study was to determine the rate of unexpected uterine pathology in postmenopausal women admitted to a gynecology clinic with symptoms other than vaginal bleeding and who were scheduled to undergo hysterectomy. MATERIALS AND METHODS: We reviewed retrospectively the medical records of 283 postmenopausal patients who had gynecological surgery between September 2007 and January 2014. We reviewed their presenting symptoms on admission, the indications for surgery, and their transvaginal ultrasonographic findings. Postoperative histopathological results based on uterine specimens were also recorded. The results were analyzed statistically. RESULTS: Of 283 patients who had surgery, 209 had no vaginal bleeding at the time of admission. From this group, 75.6% were found to have unsuspected pathology, including endometrial hyperplasia, endometrial polyps, uterine fibroids, adenomyosis, and one case of endometrial carcinoma (0.5%). The remaining 74 patients had experienced postmenopausal bleeding and in 87.8% there were pathological findings including 13 cases (17.6%) of endometrial cancer (p = 0.0001). CONCLUSION: Vaginal bleeding in postmenopausal women is indicative of a wide array of gynecological pathologies, including endometrial carcinoma. However, uterine fibroids, pelvic masses, or even endometrial cancer may develop without co-morbid vaginal bleeding. Therefore we advocate that postmenopausal women should undergo yearly screening and consultation, without waiting for an episode of vaginal bleeding.

Primary lung cancer coexisting with active pulmonary tuberculosis.

SETTING: Lung cancer and pulmonary tuberculosis (TB) comorbidity is a clinical problem that presents a challenge for the diagnosis and treatment of both diseases. OBJECTIVE: To clarify the clinical and survival characteristics of cases with both lung cancer and active pulmonary TB. DESIGN: From 2008 to 2013, 3350 TB patients admitted to the TB Department of the Chest Diseases Hospital of Izmir, Turkey, were evaluated. RESULTS: In 38 (1.1%) male patients, lung cancer and TB were found to coexist. Almost all of the patients were diagnosed at Stage III (n = 14, 36.8%) or IV (n = 17, 44.7%) lung cancer, whereas four (10.6%) had Stage II and three (7.9%) had Stage I disease. Squamous cell lung cancer was the predominant histology (n = 23, 60.7%). The median overall survival among patients was 13.4 months (95%CI 8.09-18.8). One-year survival rates for patients with Stages I, II, III and IV were respectively 100%, 75%, 57% and 40%. CONCLUSION: The present study demonstrates that lung cancer combined with active pulmonary TB most frequently presents as squamous cell carcinoma, with a male predominance. The overall survival of lung cancer patients did not change even with concomitant active TB.

A new Pseudophoxinus (Teleostei, Cyprinidae) species from Southwestern Anatolia, with remarks on the distribution of the genus in western Anatolia.

Pseudophoxinus burduricus sp. n. is described from drainages of Salda and Burdur lakes, southwestern Turkey. It is distinguished from other Anatolian Pseudophoxinus by a combination of characters: lateral line incomplete, with 21-39 (commonly 26-37) perforated scales and 47-57+1-2 scales in lateral series; 10½-12½ scale rows between lateral line and dorsal fin origin, 3-4(5) scale rows between lateral line and the pelvic fin origin; dorsal fin commonly with 7½ branched rays; anal fin commonly with 6½ branched rays; 7-8(9) gill rakers on the first branchial arch; a faint and diffuse epidermal black stripe from eye to caudal fin base in alive and preserved individuals; mouth slightly subterminal, tip of mouth cleft on about level of lower margin of eye; snout rounded, its length greater than eye diameter. Comparison is given with all Pseudophoxinus species from western Anatolia.

Alburnoides manyasensis (Actinopterygii, Cyprinidae), a new species of cyprinid fish from Manyas Lake basin, Turkey.

Alburnoides manyasensis, sp. n., is described from the Koca Stream (Lake Manyas drainage, Marmara Sea basin) in Anatolia. It is distinguished from all species of Alburnoides in Turkey and adjacent regions, Alburnoides tzanevi (Rezovska [Rezve], Istranca and Terkos streams in the western Black Sea drainage), Alburnoides cf. smyrnae (Banaz Stream, a drainage of Büyük Menderes River, Aegean Sea basin), Alburnoides fasciatus (streams and rivers in the eastern Black Sea drainage) and Alburnoides eichwaldii (Kura and Aras rivers [a drainage of Kura River], Caspian Sea basin) by a combination of the following characters (none unique to the species):marked hump at nape, especially in specimens larger than 60 mm SL; partly developed ventral keel between pelvic fin and anal fin, scaleless 1/2 to 2/3 its length; body depth at dorsal-fin origin 29-32% SL; caudal peduncle depth 11-12% SL; 45-52+ 2-3 lateral-line scales; 9-12 scale rows between lateral line and dorsal-fin origin; 4-5 scale rows between lateral line and anal-fin origin, 10½-12½ branched anal-fin rays; 40-42 total vertebrae.

Do amniotic fluid leptin levels decrease in pregnancies with fetal trisomy 21?

The objective of this study was to find a possible correlation between Down syndrome and amniotic fluid leptin. We compared 2nd trimester amniotic fluid leptin levels of fetuses with normal karyotype and with trisomy 21. We retrospectively found 15 fetuses with Down syndrome and we randomly selected 48 fetuses with normal karyotype as controls from our perinatology record database, in order to analyse their 2nd trimester amniotic fluid leptin levels. Amniotic fluid leptin levels were analysed by enzyme-linked immunosorbent assay (ELISA). The results were evaluated by Mann-Whitney U test. It was found that amniotic fluid leptin levels did not show any significant difference between amniotic fluids of fetuses with normal karyotype and those with trisomy 21 (p = 0.061). Median level of leptin was 10.06 ng/ml (range 2.10-36.69) for trisomy 21 fetuses and 14.53 ng/ml (range 2.30-67.33) for normal fetuses. In conclusion, leptin levels were not found to change in the amniotic fluids of fetuses with trisomy 21. This excludes a possible involvement of leptin in pathogenic processes associated with trisomy 21 during the fetal period and its potential employment as a diagnostic tool.

Safety and tolerability of NVA237, a once-daily long-acting muscarinic antagonist, in COPD patients.

NVA237 is a novel once-daily inhaled long-acting muscarinic antagonist administered via a dry powder inhaler. This randomized, double-blind, placebo-controlled study evaluated the safety, tolerability and bronchodilator efficacy of two doses of NVA237 (100 and 200 microg), versus placebo, in patients with moderate-to-severe COPD (forced expiratory volume in 1s [FEV(1)]>or=30% and <80% predicted and FEV(1)/forced vital capacity [FVC]<0.7, 30 min after inhalation of 80 microg ipratropium bromide). After appropriate washout periods, patients were randomized to treatment with NVA237 100 microg (n=92), NVA237 200 microg (n=98) or placebo (n=91) for 28 days. The primary objective was evaluation of safety, with efficacy measures included as secondary objectives. NVA237 was generally well tolerated and associated with a frequency and distribution of adverse events similar to placebo. Serious adverse events were uncommon and there was no evidence of adverse cardiovascular effects or unexpected events. Trough FEV(1) was significantly higher in those receiving NVA237 compared with placebo. For NVA237 100 microg the differences were 131 and 161 mL on Days 1 and 28, respectively (p<0.05), and for NVA237 200 microg the differences were 146 and 151 mL on Days 1 and 28, respectively (p<0.05). Peak FEV(1), FEV(1) at all timepoints up to 24h after dosing, and FEV(1) area under the curve during 5 min-5 h post-dosing were also significantly higher in both NVA237 groups, compared with placebo. Patients receiving NVA237 required fewer daily puffs of rescue medication and had a higher percentage of days on which rescue medication was not required. Overall, the present study provides further evidence of the safety, tolerability and bronchodilator efficacy of once-daily treatment with NVA237 100 and 200 microg in patients with moderate-to-severe COPD.

The influence of epidural volume extension on spinal block with hyperbaric or plain bupivacaine for Caesarean delivery.

BACKGROUND AND OBJECTIVE: Epidural volume extension via a combined spinal-epidural is the enhancement of a small-dose intrathecal block by an epidural injection of physiological saline solution. We evaluated the effect of epidural volume extension on the combined spinal-epidural technique of providing spinal anaesthesia for Caesarean section with hyperbaric or plain 0.5% bupivacaine. METHODS: Patients (n = 240) with height >163 cm received 9 mg and patients <163 cm received 8 mg of bupivacaine. Each study drug was combined with 20 mug fentanyl. Using the combined spinal-epidural technique, Group A (n = 60) received hyperbaric bupivacaine, and Group B (n = 60) received hyperbaric bupivacaine and 10 mL saline epidurally 5 min after subarachnoid injection. Group C (n = 60) received plain bupivacaine and Group D (n = 60) received plain bupivacaine and 10 mL saline epidurally 5 min after subarachnoid injection. An anaesthetist blinded to the anaesthetic solution injected examined the level of analgesia by the pinprick method and motor block with the modified Bromage scale for 30 min after subarachnoid injection, during the intraoperative period and subsequently every 15 min for 135 min during the recovery period. RESULTS: Time to reach a sensory block at T4 was significantly shorter in Groups C and D than in Groups A (P = 0.003 and 0.017) and B (P = 0.006 and 0.048), respectively. During the intraoperative period, sensory block levels were significantly higher in Group C than in Group A. Recovery was similar in all groups; only onset was faster in Groups C and D. CONCLUSION: There was no effect of epidural volume extension on the profile of spinal anaesthesia with the combined spinal-epidural technique for Caesarean section using hyperbaric or plain bupivacaine.

What happens when oral tuberculosis is not treated?

Pulmonary tuberculosis (TB) is the most important form of the disease, although infection may also occur by way of the intestinal tract, tonsils and skin. Oral lesions consist of persistent ulcers or granulomatous masses. A 50 year old man had been diagnosed "necrotising granulomatous inflammation" following a biopsy of a lesion on lower lip, 21 months before at a medical centre. A chest-X-ray had not been performed and he had not been given any advise in respect of treatment. He was admitted to the hospital with cough, sputum, weakness, weight loss and lesions on his lower lip. In radiology, it was detected that he had supraclavicular, submental, cervical, mediastinal lymphadenopathies, pulmonary infiltrations with cavities, thickening and roughness on left oropharengial tonsil, thickenning on inner parts of larynx and bilateral surrenal thickening. The biopsy of lesions on larynx, tonsil and epiglottis revealed "necrotising granulomatous inflammation" and histopathology supported TB infection. Sputum acid-fast bacilli was positive and culture was positive for Mycobacterium tuberculosis complex. Two months of combination treatment resulted in a gradual relief of the symptoms, radiological response, disappearing of neck swelling and healing of lesions on lip, tonsil and larynx. Although unusual oral cavity manifestations of TB are rare, clinicians should be aware of possible occurrance.

Nifedipine therapy for preterm labor: effects on placental, fetal cerebral and atrioventricular Doppler parameters in the first 48 hours.

OBJECTIVE: To assess the effect of nifedipine tocolysis on Doppler parameters of the uterine, umbilical and fetal middle cerebral arteries and atrioventricular valves in the first 48 h of therapy. METHODS: Doppler waveforms of uterine, umbilical and middle cerebral arteries and both atrioventricular valves were measured from 28 pregnant women and fetuses prior to and during nifedipine therapy for preterm labor. Maternal and fetal heart rates (FHR), maternal systolic and diastolic blood pressure, and the Doppler pulsatility index (PI) of the uterine, umbilical and middle cerebral arteries were measured. The cerebroplacental ratio (middle cerebral artery PI/umbilical artery PI) was calculated. The total time velocity integrals (TVIs) of tricuspid and mitral valves and their E- and A-wave peak velocity ratio (E/A) were measured. Friedman repeated-measures analysis of variance was used to compare the variables before and after nifedipine therapy. If significant differences were found, Wilcoxon's signed ranks test was used to analyze the difference between the two variables. A P-value of < 0.05 was considered significant. RESULTS: Nifedipine maintenance was associated with a significant decline in maternal systolic and diastolic blood pressure after 24 h, while maternal heart rate and FHR were unaffected. The uterine artery PI had decreased significantly at 24 and 48 h, while the umbilical artery PI did not change significantly. The middle cerebral artery PI had decreased significantly at 24 and again at 48 h. A significant fall in the cerebroplacental Doppler ratio was maintained beyond 24 h. The mean E/A values, TVIs and TVI x FHR values at 24 and 48 h were unchanged from the baseline values. CONCLUSIONS: Nifedipine maintenance tocolysis is associated with a significant decline in uterine artery and middle cerebral artery Doppler indices 24 h after the first dose. Fetal cardiac diastolic function is unaffected and the significant redistribution observed after 24 h is likely to be attributable to altered cerebral blood flow.

The short-term effect of nifedipine tocolysis on placental, fetal cerebral and atrioventricular Doppler waveforms.

OBJECTIVE: To evaluate the effect of nifedipine on placental and fetal middle cerebral and atrioventricular Doppler waveforms. METHODS: Doppler waveforms of uterine (UtA), umbilical (UA) and middle cerebral (MCA) arteries and both atrioventricular valves were measured from 21 pregnant women/fetuses prior to and during nifedipine therapy for preterm labor. Maternal and fetal heart rates (FHR), maternal systolic and diastolic blood pressure, the Doppler pulsatility index and systolic/diastolic ratio of the UtA, UA and MCA were measured. The total time velocity integrals (TVI) of tricuspid and mitral valves and their E-wave/A-wave (E/A) TVI ratios were measured. Wilcoxon signed pairs test was used to compare the differences in Doppler parameters before and at 3 h after nifedipine loading up to a maximum dose of 40 mg. RESULTS: Fetal arterial and UtA Doppler parameters were not different before and after nifedipine therapy. Blood flow across the atrioventricular valves and the TVI were equally unaffected by nifedipine. The TVI x FHR product was also unchanged following nifedipine therapy. CONCLUSIONS: In women with otherwise uncomplicated pregnancies, nifedipine loading and tocolysis are generally well tolerated by the mother. Placental and fetal cerebral arterial blood flow, fetal systolic and diastolic cardiac function and downstream distribution of fetal cardiac output are unaffected by nifedipine loading. These results apply to women with unchanged vital parameters. Further studies are necessary to show long-term effects of nifedipine therapy and may help to refine choice of tocolytic agents.

Risk factors for pelvic surgery.

One hundred and eighty four women who had corrective surgery for stress incontinence, genital prolapse or both were compared with two hundred and ninety women who had no surgery for these conditions. Patients and controls did not differ in terms of age, height, weight or body mass index. Younger age at first delivery (20.1+/-4.1 vs 22.8+/-4.9, p<0.000) and a smoking history (33.2% vs 23%, p<0.015) were found as risk factors for the study group. Women who underwent surgery had greater gravidity (4.85+/-2.9 vs 3.87+/-2.5, p<0.001), greater parity (3.03+/-1.9 vs 2.19+/-1.3, p<0.000), were less often nulliparous (2.2% vs 7.9%, p<0.008), less likely to have had a cesarean delivery (1.1% vs 9%, p<0.001) and more likely to have had a vaginal delivery (97.3% vs 85.9%, p<0.000) than the control group. The study group have had larger neonates on average (3800+/-416 vs 3373+/-637 gm's, p<0.000) and had greater use of forceps or vacuum extractor for at least one delivery (17.9% vs 7.6%, p<0.001). Highly significant relationship was found between the risk of having corrective surgery and the number of children born vaginally. Women who had 4 or more vaginal deliveries had 11.7 times more risk of urinary incontinence or genital prolapse.

The effect of ascites, mass volume, and peritoneal carcinomatosis on serum CA125 levels in patients with ovarian carcinoma.

The aim of this study is to investigate the effects of ascites, ovarian mass volume, and peritoneal carcinomatosis on serum CA125 levels in patients with nonmucinous epithelial ovarian carcinoma. Serum CA125 levels were determined by a commercial enzyme immunoassay kit in a series of 98 patients with stage I-IV nonmucinous epithelial ovarian carcinoma. Amounts of ascites were determined in each patient with ascites. Ovarian mass volumes were calculated in 22 patients with stage I disease without ascites. Peritoneal carcinomatosis was detected in 35 ovarian cancer patients. Serum CA125 levels were compared among the patients with different clinical conditions. Serum CA125 levels were significantly higher in cases of ovarian cancer with ascites when compared with those without ascites (P < 0.01). Abnormal levels of serum CA125 were found in 80% of all patients; these abnormal levels were detected in 92% and 97% of the patients with ascites and with peritoneal carcinomatosis, respectively. A positive correlation between serum CA125 levels and ascites amounts was found in patients with ascites (P < 0.01, r = 0.74). However, there was no correlation between ovarian mass volumes and levels of serum CA125 in patients having stage I disease but no ascites (P = 0.5, r = 0.15). Our results showed that serum CA125 levels might be affected by the amount of ascites and the presence of peritoneal carcinomatosis but not with ovarian mass volume. However, these findings need to be confirmed in more and larger studies. These results may be beneficial in the management of ovarian carcinoma patients with elevated CA125 levels.

[A case of upper gastrointestinal system obstruction by duodenal intramural hematoma caused by using an oral anticoagulant drug]. / Oral antikoagulana bagli duodenal intramural hematomun olusturdugu üst gastrointestinal sistem obstrüksiyonu olgusu.

Unwanted haemorrhage can be seen due to long-term oral anticoagulant use. Sometimes these may lead obstructions forming intramural haemotomas. We noticed a case of duodenal obstruction due to an intramural hematoma in a patient who is on chronic oral anticoagulant therapy. In Taksim Hospital 1st General Surgery Department in April 2000, we treated a patient who presented anaemia, jaundice, pyloric obstruction conservatively. As a result we implicated to treat such cases nonoperatively.

May cathepsin D immunoreactivity be used as a prognostic factor in endometrial carcinomas? A comparative immunohistochemical study.

OBJECTIVE: To investigate the prognostic value of immunohistochemical detection of cathepsin D and the association between cathepsin D and established prognostic factors in endometrial carcinoma. METHODS: Cathepsin D immunoreactivity was determined by an immunohistochemical technique in a series of 79 patients with surgical stage I-III primary endometrial carcinoma. RESULTS: Of 79 tissue specimens, 48 (61%) showed a positive reaction for cathepsin D. A significant correlation between cathepsin D and histological grade was found (P < 0.05). The other established clinicopathological prognostic factors were not associated with cathepsin D. There was not any significant difference in prognosis between the positive cases and negative cases for cathepsin D (P > 0.05). In the univariate analysis cathepsin D immunoreactivity did not show significant prognostic value for overall survival (P > 0.05). The multivariate analysis also showed that cathepsin D was not related to patient outcome (P = 0.24, relative risk = 0.34, 95% confidence interval = 0.05-2.09). CONCLUSIONS: Our results suggest that cathepsin D immunoreactivity may not be of prognostic value but more studies are needed to evaluate the relationship between its immunoreactivity in tumor cells and in other cells.

Ecophysiological studies in Kalanchoë porphyrocalyx (Baker) and K. miniata (Hils et Bojer), two species performing highly flexible CAM.

Preceding results, based on the determination of stable carbon isotope composition (δ13C) of leaf tissues from various Kalanchoë species, suggested a close coincidence between the photosynthetic flexibility of the species and their habitat, life form and taxonomic position within the genus. The ability to shift from C3-to Crassulacean Acid Metabolism (CAM)-type of photosynthesis seemed to concern in particular the more ancestral species in the genus and to be linked to epiphytism and changing climatic situations. For deeper insights into these interrelationships, physiological studies in controlled conditions were carried out on K. miniata and K. porphyrocalyx. These two species differ by their habitat preference and life form. Measurements were conducted on CO2 exchange patterns, day/night fluctuation of malate content in the leaves and 'capacity' of phosphoenolpyruvate carboxylase (PEPC). The results show that the 2 species can be considered as 'facultative' CAM plants, with very high flexibility in their photosynthetic behaviour. The decrease in water availability seems to be a major factor triggering the shift from C3 to the CAM mode. In K. miniata, 21 days of drought depressed CO2 uptake to the level of CAM idling whereas in K. porphyrocalyx, CO2 exchange was considerably more resistant. At least for K. miniata, short-day treatment was found to be a further CAM-inducing factor. The results are discussed in terms of their ecophysiological significance under the environmental conditions of the sites where the investigated species naturally grow.
