Evaluation of plasma cholecystokinin levels and gallbladder functions in hyperemesis gravidarum: a prospective cohort study.

This is a prospective cohort study aimed to compare women treated due to hyperemesis gravidarum (HG) (n = 24) to women with normal pregnancy attending regular antenatal outpatient care (n = 22) in terms of fasting and post-prandial cholecystokinin (CCK) levels, and gallbladder (GB) functions. The Pregnancy-Unique Quantification of Emesis (PUQE) scores, fasting and postprandial CCK levels, and ultrasonographic GB parameters were recorded at admission before any treatment. The median PUQE score in the study group was 8. There were no statistically significant differences in GB parameters (p>.05), and fasting and postprandial CCK levels between the groups (p=.851, p=.395, respectively). Fasting CCK levels were positively correlated with postprandial GB volume (PGv) (p=.022, r = 0.464). Although GB contractility is compromised during pregnancy, HG does not cause further GB impairment. The positive correlation between fasting CCK levels and PGv requires further evaluation. Impact StatementWhat is already known on this subject? The pathophysiology of hyperemesis gravidarum (HG) remains poorly understood. Altered cholecystokinin (CCK) levels may have potential consequences on gastric emptying, which may be related to nausea and vomiting. In this context, alterations in CCK secretion in women diagnosed with HG have been previously reported, and alterations in CCK levels lead to impaired gallbladder (GB) functions.What do the results of this study add? CCK levels and GB functions in pregnant women with HG are not statistically significantly different from those in healthy pregnant women.What are the implications of these findings for clinical practice and/or further research? Further studies designed in patients with different severities of HG and larger sample sizes are required for a better understanding of HG pathophysiology.

The assessment of the relationship between the vascularity of FIGO Type 4-7 leiomyomas and abnormal uterine bleeding.

The current study aimed to analyse and compare the vascularity of FIGO Type 4-7 leiomyoma specimens obtained from women with or without abnormal uterine bleeding (AUB). The records of 31 women who underwent myomectomy for FIGO Type 4-7 leiomyomas in a university hospital setting were analysed. Group I (n = 16) was composed of women that were symptomatic for AUB and group II (n = 15) consisted of asymptomatic cases. The myomectomy material(s) of each case were processed with CD34 staining and evaluated by Image J® software (Image J 1.52a, Wayne Rasband National Institutes of Health, Bethesda, MD). There was no statistically significant difference between the rates of vascular areas in the specimens of the two groups (p>.05). Although areas with large vessels were higher in group I compared to group II, the difference did not reach statistical significance (p>.05). AUB caused by FIGO Type 4-7 leiomyomas seems to be related to factors other than vascular density.Impact StatementWhat is already known on this subject? Uterine leiomyomas are the most common benign gynaecologic neoplasms with a prevalence of approximately 40% in women of reproductive age. They are most often asymptomatic but when symptomatic, abnormal uterine bleeding (AUB) is one of the most commonly observed symptoms. Although there are some hypothetical explanations, the exact pathogenesis underlying leiomyoma-associated AUB has not yet been elucidated. Almost a century ago, the vascular abnormalities of fibroids were hypothesised as one of the etiopathological factors correlated with clinical symptoms, such as AUB, and current data suggest that the vascular map of leiomyomas consists of an avascular core surrounded by a vascularised capsule. To our knowledge, there are no studies in the literature comparing the histopathological evaluation of the vascularity scores of FIGO Type 4-7 leiomyomas in symptomatic (with AUB) and asymptomatic (without AUB) women.What the results of this study add? The study revealed that there was no statistically significant difference between the vascularity scores of FIGO Type 4-7 leiomyomas excised from the symptomatic and asymptomatic women. Large vessel densities also did not statistically significantly differ between the two groups.What the implications are of these findings for clinical practice and/or further research? This study revealed that AUB caused by FIGO Type 4-7 leiomyomas was related to factors other than vascular density.

Homocysteine and C-reactive Protein Levels in Women with Polycystic Ovary Syndrome.

OBJECTIVES: Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in infertile women characterized by both reproductive and metabolic dysfunctions of different degrees. Furthermore, it has been associated with increased cardiovascular disease (CVD) risk and related long-term health sequela. The aim of this study is to evaluate serum homocysteine (Hcy) and C-reactive protein (CRP) levels in women with PCOS and to evaluate their relationship with clinical and laboratory parameters in women with PCOS. MATERIALS AND METHODS: The prospective single-center study included 45 women with PCOS (study group) and 41 control subjects. Demographic variables and Hcy, CRP, fasting blood glucose, insulin, follicle-stimulating hormone, luteinizing hormone, estradiol, total and free testosterone, dehydroepiandrosterone sulfate, thyroid-stimulating hormone levels, and lipid profiles of the subjects were recorded. homeostatic model assessment for insulin resistance (HOMA-IR) indexes were calculated. RESULTS: Fasting plasma glucose, insulin, HOMA-IR, free and total testosterone levels, and clinical hirsutism were significantly higher in the study group. There was no statistically significant difference in lipid profile between groups. Hcy and CRP levels were higher in the study group, which was not statistically significantly different (P > 0.05). CONCLUSION: Some of the parameters that are correlated with CVD risk were found to be higher in women with PCOS, although the difference for Hcy and CRP did not reach statistical significance. However, the current study reveals that the CVD risk associated with PCOS deserves more comprehensive prospective studies with long-term outcomes.

The levels of matrix metalloproteinase-9 and neutrophil gelatinase-associated lipocalin in different stages of endometriosis.

This study was designed to explore matrix metalloproteinase-9 (MMP-9), neutrophil gelatinase-associated lipocalin (NGAL) levels and MMP-9/NGAL ratio in women with and without endometriosis diagnosed surgically and/or histopathologically. The correlation between biomarkers and the severity of the disease is analysed. The revised American Fertility Society classification system was used to determine the severity of endometriosis. Serum MMP-9 and Ca125, urine NGAL levels were measured in all participants. Serum MMP-9 levels were significantly higher in the study group (n = 60) compared to controls (n = 31) (15.0 pg/mL (6.0-143.0) vs. 12.0 (4.0-18.0), respectively; p=.002). MMP-9 levels were significantly higher in severe endometriosis compared to mild endometriosis subgroups (p<.001). No significant difference was found between NGAL levels in study and control groups (p>.05). The diagnostic value of MMP-9 and NGAL is not superior than CA-125 for endometriosis. Nevertheless, MMP-9 might be a potential predictive marker for advanced stage of the disease. Impact Statement What is already known on this subject? The gold standard diagnostic test for diagnosis of endometriosis is laparoscopy combined with histopathological confirmation of eutopic endometrial glands and/or stroma. Both invasiveness and possible accompanying complications limit the preference regarding the surgical approach. Among non-invasive markers none has been accepted as gold standard neither for diagnosis nor for determining the severity of the disease. MMPs are extracellular endopeptidases, which have a significant role in degradation and remodelling of extracellular matrix for cellular migration and invasion. Among these, MMP-9 has been shown to be higher in eutopic/ectopic endometrial tissue in women with endometriosis and has been suggested to have a role in pathogenesis of endometriosis by promoting invasion of the endometriotic lesions. NGAL is an acute phase protein, which is involved in a variety of physiological and pathophysiological processes. The molecule has also been revealed to correlate with endometriosis pathophysiology through the epithelial-mesenchymal transition process which is the basis for the onset of endometriosis. But also, NGAL which composes a complex with MMP-9 (MMP-9 and NGAL complex), has been shown to protect MMP-9 from autodegradation in vitro which might be a contributing factor for endometriosis pathophysiology. What the results of this study add? MMP-9 cut-off level for prediction of severe endometriosis is a novel finding obtained from this study with acceptable sensitivity and specificity. On the other hand, NGAL seems to have no significant value either for diagnosis of for determining severity of the disease. After all, MMP-9 might be an easy use acceptable biomarker for endometriosis but further studies on larger populations are needed. What the implications are of these findings for clinical practice and/or further research? MMP might be a potential non-invasive predictive marker for advanced stage disease.

Neutrophil Gelatinase-Associated Lipocalin Levels During Pneumoperitoneum.

BACKGROUND AND OBJECTIVES: A temporary deterioration in renal function during pneumoperitoneum has been reported, but the extent is not known. A new marker for the early detection of renal injury, neutrophil gelatinase-associated lipocalin (NGAL), has been shown to increase in various conditions that affect renal function. This study was conducted to explore detrimental effects of pneumoperitoneum in laparoscopic surgery on renal function by studying levels of urinary NGAL (uNGAL). METHODS: Thirty-two women scheduled to undergo laparoscopic surgery in a gynecology clinic were recruited. NGAL was measured in urine collected at the beginning (0 h) and at 2 and 24 hours after the initiation of surgery. Hemodynamic parameters were analyzed immediately after intubation and before desufflation. RESULTS: Levels of uNGAL increased from 5.45 ng/mL at 0 hours to 6.35 ng/mL at 2 hours and to 6.05 ng/mL at 24 h; however, there was no significant change in uNGAL levels at the collection time points. Intraoperative oliguria was observed in all cases, and the severity increased with the duration of surgery. uNGAL levels did not correlate with the duration of surgery or pneumoperitoneum. CONCLUSION: In patients with normal renal functions, pneumoperitoneum results in transient oliguria without any early renal damage, as indicated by nonsignificant changes in uNGAL levels.

Effects of different doses of tramadol added to levobupivacaine in continuous wound infusion for postoperative pain treatment following cesarean section.

OBJECTIVE: The aim of this study was to compare the effects of two different doses of tramadol added to levobupivacaine as continuous wound infusion, on VAS scores following cesarean section. METHODS: The study was conducted in an University Hospital and was approved by the Local Ethical Committee. Sixty-five ASA I-II parturients, between 18 and 45 years were enrolled. The participants were randomized to three groups. Group T1 (n = 21) was given the study solution consisting of levobupivacaine 0.25% + tramadol 1 mg/kg. Group T2 (n = 21) was given levobupivacaine 0.25% + tramadol 2 mg/kg and Group L (n = 21) was given levobupivacaine 0.25%, subcutaneously, alone. Each patient who delivered by cesarean section was applied a triple orifice epidural catheter above rectus fascia for continious wound infiltration. VAS at rest and with 20 degrees leg lift, time to first additional analgesic, total additional analgesic consumption, side effects, and sedation scores were recorded. RESULTS: There were no statistically significant differences among groups, concerning VAS scores at rest and VAS scores at leg lift. Total amount of additional analgesics and sedation scores were also similar for three groups. CONCLUSION: Different doses of tramadol as adjunct to local anesthetics in continuous wound infiltration following cesarean section do not seem to provide superior analgesia.

Single-organ vasculitis of the cervix accompanying human papillomavirus infection.

Single-organ vasculitis (SOV) has rarely been reported to involve the female genital tract but mostly the uterine cervix. A 39-year-old woman was diagnosed to have a high-grade cervical intraepithelial lesion and was treated by large loop excision of the transformation zone. Histopathological evaluation of the excised specimen confirmed the diagnosis of cervical intraepithelial neoplasia grade III accompanied by human papillomavirus infection. The excised second specimen showed the evidence of vasculitis of medium-sized vessels of the cervix, which is a quite rare form of SOV. It seems to be important to be aware of the localized form of polyarteritis nodosa limited to the female genital tract to prevent unnecessary immunosuppressive therapies.

Electrocardiographic P-Wave Duration, QT Interval, T Peak to End Interval and Tp-e/QT Ratio in Pregnancy with Respect to Trimesters.

BACKGROUND: P-wave duration helps to determine the risk of atrial arrhythmia, especially atrial fibrillation. QT interval, T peak to end interval (Tp-e), and Tp-e/QT ratio are electrocardiographic indices related to ventricular repolarization which are used to determine the risk of ventricular arrhythmias. We search for any alterations in electrocardiographic indices of arrhythmia in the pregnancy period with respect to trimesters. METHODS: We enrolled 154 pregnant and 62 nonpregnant, healthy women into this cross-sectional study. Maximum and minimum P-wave durations (Pmax, Pmin), and QT intervals (QTmax, QTmin) were measured from 12 leads. QT measurements were corrected using Fridericia (QTc-Fr) and Bazett's (QTc-Bz) correction. Tp-e interval was obtained from the difference between QT interval, and QT peak interval (QTp) measured from the beginning of the QRS until the peak of the T wave. Tp-e/QT ratio was calculated using these measurements. RESULTS: Pmax were 93.0 ± 9.1, 93.9 ± 8.9, 97.9 ± 5.6, 99.0 ± 6.1 in nonpregnant women, first, second, third trimesters of pregnancy, respectively (P = 0.001); whereas Pmin values were not significantly different. QTc-Fr max were 407.4 ± 14.2, 408.5 ± 16.1, 410.1 ± 13.1, 415.1 ± 10.1 (P = 0.007); Tp-e were 72.7 ± 6.2, 73.2 ± 6.5, 77.2 ± 8.9, 87.2 ± 9.6 (P < 0.001); and Tp-e/QT were 0.17 (0.14-0.20), 0.17 (0.14-0.20), 0.18 (0.15-0.23), 0.20 (0.16-0.25) in nonpregnant women, first, second, and third trimesters of pregnancy respectively (P < 0.001). None of the participants experienced any arrhythmic event. CONCLUSIONS: P-wave duration is prolonged in the second trimester, and resumes a plateau thereafter. Maximum QTc interval, Tp-e interval and Tp-e/QT ratio are increased in the late pregnancy. Although these indices are altered during the course of pregnancy, they all remain in the normal ranges.

The prognostic value of first-trimester cystatin C levels for gestational complications.

AIMS: This study is designed to evaluate predictive value of first-trimester cystatin C levels for long-term pregnancy complications. METHODS: The cross-sectional study population consisted of patients who admitted to outpatient clinic of a Maternity Hospital between September 2013 and December 2014. Among the 203 participants who accepted to participate in the study, 174 subjects who continued antenatal follow-up in the same clinic were included in the final analyses. Cystatin C, blood urea nitrogen, Creatinine levels and estimated glomerular filtration rates were evaluated in the first-trimester routine antenatal visit. Mode of delivery and gestational complications were noted. RESULTS: First-trimester cystatin C levels were significantly higher in cases complicated with preterm delivery and premature rupture of membrane (PROM) compared to uncomplicated ones (0.58±0.07 vs. 0.55±0.07, P=0.041, and 0.58±0.07 vs. 0.55±0.07, P=0.036). With a cutoff value of 0.505 mg/L, sensitivity of cystatin C for preterm delivery and PROM was 91.9% and specificity was 27.7% with a negative predictive value of 92.3% and a positive predictive value of 26.6%. CONCLUSION: Detection of cystatin C levels in the first trimester of pregnancy for the prediction of preterm/PROM seems as a promising preliminary data. The relatively higher first-trimester cystatin C levels in complicated pregnancies are conspicuous. The results imply that in pregnancy cystatin C might be more than a marker for renal function.

The association between ischemia modified albumin and placental histopathology in uncomplicated term deliveries.

Ischemia modified albumin (IMA) is a marker of ischemia elevated in different clinical conditions and its use for hypoxia in perinatology is of current interest. We aimed to investigate the association between maternal and cord blood IMA levels and placental histopathological findings in uncomplicated term deliveries. In this study, placental histopathological evaluation in uncomplicated deliveries that ended with healthy newborns revealed 80.6% vasculopathy. The results support the hypothesis that hypoxia exceeding the placental reserve ends with fetal compromise. Moreover, the presence of maternal vasculopathy in placenta is not correlated with maternal and fetal IMA levels.

Early second trimester retinol-binding protein-4 values in cases with or without gestational diabetes mellitus risk factors: a cross-sectional study.

AIM: Retinol-binding protein-4 (RBP-4) has been correlated with different degrees of insulin resistance including gestational diabetes mellitus (GDM). Presence of risk factors for GDM is an indication for early screening. We studied RBP-4 values in the early second trimester of pregnancy in pregnant subjects with or without GDM risk factors and compared the results by routine GDM screening methodology. METHODS: Seventy-nine patients with at least one GDM risk factor and 46 patients without any GDM risk factors were enrolled in the cross-sectional study as risk and control groups, respectively. In the early second trimester, RBP-4 values were measured, in addition to fasting plasma glucose and 50-g glucose challenge test in all subjects. RESULTS: The RBP-4 values in 16-18th weeks of pregnancy were not significantly different between risk and control groups (95.3 ± 20.1 vs 103.1 ± 24.4 µg/mL, respectively; P = 0.055) although fasting plasma glucose levels and 50-g glucose challenge test results were higher in the risk group than the control group (75.3 vs 69.3 mg/dL and 112.4 vs 97.5 mg/dL, respectively; P < 0.05). CONCLUSION: Presence of GDM risk factors does not have an impact on early second trimester RBP-4 values in pregnant subjects.

CRP at early follicular phase of menstrual cycle can cause misinterpretation for cardiovascular risk assessment.

OBJECTIVE: C-reactive protein (CRP) is a well-known marker of inflammation and infection in clinical practice. This study is designed to evaluate CRP levels in different phases of menstrual cycle, which might end up with misleading conclusions especially when used for cardiovascular risk assessment. METHODS: Twenty-seven women were eligible for the cross-sectional study. Venous blood samples from each participant were collected twice during the menstrual cycle. The first sampling was held at 2nd to 5th days of the menstrual cycle for FSH, estradiol, CRP, and sedimentation, and the second was done at 21st to 24th days of the menstrual cycle for measurement of progesterone, CRP, and sedimentation values. RESULTS: CRP values were significantly higher in the early follicular phase compared to luteal phase (1.8 mg/L [0.3-7.67] vs. 0.7 mg/L [0.1-8.3], p < 0.001, respectively). In both phases of the menstrual cycle, sedimentation rate was similar (12.1 ± 6.7 vs. 12.3 ± 7.7; p = 0.717, respectively). CONCLUSIONS: CRP levels in early follicular phase of the menstrual cycle (menstruation) are significantly higher than CRP levels in luteal phase of the same cycle. In reproductive age women, detection of CRP for cardiovascular risk assessment during menstruation might not be appropriate.

Improved cycle outcomes after laparoscopic ovarian diathermy in hyper-responder patients with previous ART failure.

Excessive response to ovarian stimulation is common among hyper-responder patients undergoing assisted reproductive technology (ART). Cycle cancellations and severe ovarian hyperstimulation syndrome (OHSS) are all detrimental consequences observed within this cohort and several approaches have been proposed to enhance outcomes. The current study is designed to evaluate whether laparoscopic ovarian diathermy (LOD) improves ART outcomes and pregnancy rates by reducing Anti-mullerian hormone (AMH) levels in a group of patients who had a history of recurrent ART failure and high response. A total of 40 hyper-responder patients with history of previous ART failure were included. Group I consisted of 22 patients that underwent LOD prior to ART. Group II consisted of 18 patients that underwent only ART. Cycle outcomes of groups were compared. Following LOD, significant reduction in AMH levels were detected in group I (4.75 ng/mL to 2.25 ng/mL). Clinical pregnancies were similar among groups (40% versus 27.8% p = 0.65). There was no cycle cancellation in Group I, whereas there were three cycle cancellations observed due to OHSS in Group II. Our results indicate that LOD might offer enhanced fertility outcomes and may reduce the likelihood of cycle cancellations in hyper-responders with previous ART failures.

Body satisfaction and eating attitudes among girls and young women with and without polycystic ovary syndrome.

PURPOSE: The main goal of the current study was to examine the associations between polycystic ovary syndrome (PCOS) and body dissatisfaction and eating attitudes in a sample of adolescent girls and young women. Body dissatisfaction is 1 of the strongest predictors of the development of negative outcomes such as low self-esteem, and eating disorders. In adolescent age group of patients, both hirsutism and increased body mass index, appearing with PCOS, may be the leading symptoms also resulting or contributing to body dissatisfaction and eating disorder. MATERIALS AND METHODS: The sample of 94 Turkish adolescent girls and young women [PCOS (n = 42) vs non-PCOS (n = 52)] completed measures of figure rating scale, the socio-cultural attitudes toward appearance questionnaire, body esteem scale, eating attitude test, and demographics. RESULTS AND CONCLUSION: The results revealed that body esteem was important for predicting eating attitudes in both groups and sociocultural internalization of thinness ideal and body dissatisfaction were also significant factors in PCOS group. However, scores for major study variables (BMI, sociocultural attitudes toward awareness and internalized appearance ideals, body esteem subscales, body dissatisfaction and eating attitudes) in the PCOS group were not significantly higher than those for girls without PCOS.

Incidental diagnosis of unilateral renal and adnexal agenesis in a 46-year-old multiparous woman.

PATIENT: Female, 46 FINAL DIAGNOSIS: Unilateral adneksial and renal agenesis Symptoms: Menometrorrhagia Medication: - Clinical Procedure: Total abdominal hysterectomy and unilateral salphingoopherectomy Specialty: Obstetrics and gynecology. OBJECTIVE: Rare disease. BACKGROUND: Unilateral renal and adnexal agenesis is quite rare. Absence of any uterine abnormality accompanying current urogenital abnormalities is even rarer. CASE REPORT: We report on the case of a 46-year-old multiparous woman, incidentally diagnosed to have unilateral renal, ovarian, and tubal agenesis just before hysterectomy due to menometrorrhagia and myoma uteri. CONCLUSIONS: Any diagnosis of a urogenital abnormality necessitates investigation of comorbid renal or genital abnormalities.

The impact of route of anesthesia on maternal and fetal ischemia modified albumin levels at cesarean section: a prospective randomized study.

OBJECTIVE: Ischemia modified albumin has been shown to increase in ischemic situations, and has also been shown to increase in fetal cord blood in deliveries by cesarean section. The aim of this study is to reveal whether anesthesia has an impact on maternal and fetal cord ischemia modified albumin levels. METHODS: Seventy two women with uncomplicated term pregnancies were randomized to spinal (n=37) or general anesthesia (n=35) groups. The blood pressure, oxygen saturation, and pulse rate of the patients were recorded during the procedure. Maternal blood samples of ischemia modified albumin (IMA) were taken 10 min from the start of the procedure. The fetal cord blood samples of IMA were taken immediately after birth. RESULTS: Maternal (0.99 ± 0.19 vs. 0.80 ± 0.27) and fetal (1.00 ± 0.21 vs. 0.70 ± 0.26) IMA levels were significantly higher in the general anesthesia group. Fetal IMA levels were positively correlated with maternal gravidity (r=0.31; P=0.008), parity (r=0.25; P=0.028), and fetal birth weight (r=0.23, P=0.045). Also, as time from incision to delivery lengthens, fetal IMA levels increase (r=0.29, P=0.012). CONCLUSION: Fetal cord ischemia modified albumin levels were higher in the general anesthesia group, therefore, it is proposed that regional anesthesia should be the preferred route of anesthesia for an elective cesarean section, at least until the impact of high fetal cord IMA levels are manifested.
