Spot Urine Protein-to-Creatinine Ratio to Predict the Magnitude of 24-Hour Total Proteinuria in Preeclampsia of Varying Severity.

OBJECTIVE: The predictive value of spot urine protein-to-creatinine ratio (PCR) for estimating total 24-hour proteinuria in severe preeclampsia is unclear. This study aimed to assess the diagnostic accuracy of spot urine PCR for ascertaining the magnitude of proteinuria in women with preeclampsia of varying severity. METHODS: A total of 205 patients with prediagnosed preeclampsia were included in this prospective cohort study. Patients were allocated into one of the three groups categorized by severity of disease, as follows: gestational hypertension, group 1 (n = 41); preeclampsia, group 2 (n = 88); and severe preeclampsia, group 3 (n = 76). We assessed the spot urine PCRs to determine significant proteinuria and the magnitude of proteinuria in these groups. RESULTS: The spot urine PCR was 0.53, with 81% sensitivity and 93% specificity to detect significant proteinuria. A significant correlation was found between PCR and 24-hour total proteinuria in group 1 (r = 0.473, P = 0.002). There were also significant correlations in group 2 (r = 0.814, P < 0.001) and group 3 (r = 0.912, P < 0.001). The established formula using spot urine PCR to estimate 24-hour total proteinuria in severe preeclampsia was Y = 832.02X + 378.74 mg (r2 = 0.8304). CONCLUSION: Although 24-hour urine collection remains a merely reliable test to determine the degree of total proteinuria, our findings suggest that it is likely to assess the magnitude of proteinuria by the spot urine PCR, especially in severe preeclampsia.

Troponin T and NT ProBNP Levels in Gestational, Type 1 and Type 2 Diabetic Mothers and Macrosomic Infants.

This study compares NT proBNP and troponin T levels in umbilical cord arterial blood and postnatal echocardiographic findings for infants of gestational and pregestational diabetic mothers and macrosomic infants. Twenty-seven infants of pregestational diabetic mothers, 61 infants of gestational diabetic mothers and 37 macrosomic infants of nondiabetic mothers were prospectively enrolled in this study along with a control group of 58 healthy infants of mothers without any pregestational or gestational disorders as the control group. All enrollees were born after 34 weeks of gestation. For this study, umbilical cord blood was drawn during delivery to determine NT proBNP and troponin T levels. Echocardiography was performed 24-72 h after the delivery. Umbilical cord troponin T and NT proBNP levels were found to be higher in the diabetic and macrosomic groups than in the control group (all of them p < 0.001). NT proBNP levels were positively correlated with interventricular septum thickness in the pregestational and gestational infants of diabetic mothers groups (r = 0.564 and r = 0.560, respectively, p < 0.01). Both pregestational and gestational diabetic mothers were divided into two groups according to HbA1c levels in the third trimester as good (<6.1 %) and suboptimal (>6.1 %) metabolic control. In the good and suboptimal metabolic control diabetic groups, NT proBNP levels were also positively correlated with interventricular septum thickness (r = 0.536 and r = 0.576, respectively, p < 0.01). In the suboptimal metabolic control diabetic group, NT proBNP was only found to be positively correlated with the left ventricular mass index (r = 0.586, p < 0.01). While there was no correlation in the myocardial performance index between infants of diabetic mothers and the control group, the myocardial performance index of macrosomic infants was lower than that of the control group (p = 0.017). Cardiac biomarkers (NT proBNP and troponin T) were elevated in infants of diabetic mothers and macrosomic infants. While there was a positive correlation between NT proBNP levels and cardiac structure in infants of pregestational and gestational diabetic mothers, there was no relationship between NT proBNP levels and cardiac function.

Comparison of two misoprostol regimens for mid-trimester pregnancy terminations after FIGO's misoprostol dosage recommendation in 2012.

OBJECTIVE: To compare the safety and efficacy of two misoprostol regimens for mid-trimester pregnancy terminations. METHODS: Retrospective analysis of 263 cases of pregnancy terminations with misoprostol between 12 and 24 weeks was performed. Group 1 (total 129 patients) consisted of patients who were given 200 mcg vaginal misoprostol every 4 h until the abortion, whereas Group 2 patients (total 134 patients) were given misoprostol as in International Federation of Gynecology and Obstetrics's (FIGO) 2012 recommendation. In case of a previous cesarean section doses were halved in both groups. Primary outcomes of the study were the time to abortion and the total drug dose used. Secondary outcome was the rate of complications. RESULTS: Total dose and time to abortion did not differ between the groups. As for complications, one patient (%0.8) in group 1 developed HELLP syndrome and had hysterotomy. One patient (%0.8) in group 2 had uterine rupture and had total hysterectomy. Two patients in both groups considered failure of induction and terminated with surgery (hysterotomy). Groups did not show difference in induction failure rates. CONCLUSIONS: We respect the presence of dose recommendation stated by the FIGO and found similar results with our recent protocol. Other misoprostol regimens used worldwide should also be compared with this guideline in order to improve its efficacy.

Fetal Oropharyngeal and Neck Tumors: Determination of the Need for Ex-Utero Intrapartum Treatment Procedure.

BACKGROUND: The aim of this study was to assess the ex-utero intrapartum therapy (EXIT) applied to 3 of the 7 cases with oropharyngeal or neck masses and review the indicators of the need for an EXIT procedure. CASE REPORT: Prenatal presentation, size and localization of the masses, existence of fetal hydrops and associated findings such as polyhydramnios, intraoperative managements, complications, and maternal and neonatal outcomes were evaluated through a retrospective analysis. Four cases had neck masses and three cases had oropharyngeal masses. Prenatal sonography was used as the main diagnostic tool for all patients. The median gestational age was 34.5 weeks at the time of diagnosis and 36 weeks at delivery. Polyhydramnios was observed in three of the seven cases and they were delivered prematurely. Interventions such as endotracheal intubation or tracheostomy were performed to provide patency of the airway during delivery by the EXIT procedure in three cases. Hemangioma was found in two cases, teratoma in two cases, lymphangioma in two cases and hamartoma in one case following pathological examination of the masses. CONCLUSION: The localization of mass, its characteristics, invasion (if it exists), and relation to the airway are the main factors used to determine the need for EXIT. The presence of polyhydramnios may be an important indicator to predict both the need for EXIT and fetal outcomes.

Perinatal autopsy evaluation of 2150 autopsies in the Çukurova region of Turkey.

OBJECTIVE: We aimed to document the reasons of perinatal deaths in a large autopsy series performed in our institute, which is a reference center in the Çukurova region of Turkey. MATERIAL AND METHOD: The study included 2150 autopsies performed between January 2000 and December 2012 at our institute. Diagnoses were categorized according to the detected pathologies; congenital malformations were detailed based on systems. RESULTS: A pathology was detected in 1619 of 2150 (73.3%) autopsies. Congenital malformations were the most common diagnosis with 68.2%. Neural tube defects and central nervous system malformations were the most frequent system malformation in 28.8% of cases, followed by the urogenital system (11.4%) and musculoskeletal system (8.3%), respectively. Malformation syndromes including multisystem anomalies were defined in 109 cases (9.3%). CONCLUSION: Congenital malformations are the most common reason for perinatal deaths, with autopsy having an additive role to prenatal and genetic evaluations and providing foresight for planning a subsequent pregnancy.

The necessity of using tenaculum for endometrial sampling procedure with pipelle: a randomized controlled study.

OBJECTIVE: To evaluate the use of tenaculum on pain perception of patients and on ease of endometrial sampling procedure with a pipelle. METHODS: A randomized controlled trial was conducted in 118 patients for assessing pain perception and the ease of the procedure. Patients were randomly assigned to group 1 (without tenaculum) and group 2 (with tenaculum). Visual analog scale (VAS) was used to assess patients' pain at four different times during the process. VAS-3 reflected the pain during the procedure. Likert scale was employed by the surgeon to measure the ease of the procedure. Main outcome was VAS and the secondary outcomes were Likert scale and success rate in obtaining adequate samples of endometrial tissue for histopathological diagnosis. RESULTS: Endometrial sampling procedure could not be performed only on three patients who belonged to group 1. The VAS-3 scores were higher in group 2 than group 1 (p = 0.001). Nullipar patients had higher VAS-3 scores than multipars (p = 0.012). VAS-3 did not vary in pre-peri-postmenopausal women (p = 0.901). Likert scale was lower in postmenopausal women than peri- or pre-menopausal patients (p = 0.020, 0.017, respectively). Use of tenaculum was found by logistic regression analysis to be an independent risk factor for patients' pain perception (p = 0.0001, RR 31.8, 95 % CI 8.3-122.4). Inadequate endometrial sampling was reported in 12 patients who were all postmenopausal. CONCLUSION: Endometrial sampling procedure without tenaculum is feasible and yields less pain perception than with tenaculum.

Comparison of clinical and laboratory findings in early- and late-onset preeclampsia.

OBJECTIVE: To compare clinical and laboratory findings between the early-onset preeclampsia (EOP) and late-onset preeclampsia (LOP). METHODS: This prospective longitudinal study was performed at a tertiary referral university clinic. All patients meeting the inclusion criteria were divided into two groups, the EOP group and the LOP group, according to gestational age at the onset of disease. The distinction criterion for early versus late onset was set as week 34 of gestation. Clinical and laboratory findings, and maternal-perinatal outcomes were compared between the groups. RESULTS: A total of 157 patients with preeclampsia were included. A significant difference was observed between the groups in terms of diagnosis and severity of the disease (p = 0.007 and <0.001, respectively). The history of previous preeclampsia, diastolic blood pressure and hourly urine output on admission to the hospital were significantly different between the groups (p = 0.016, 0.018 and 0.024, respectively). Latent period for delivery and postpartum hospitalization time were longer in the EOP group than in the LOP group (p = 0.024 and 0.002, respectively). The patients with EOP received betamethazone (p < 0.001) and MgSO4 (p = 0.029) more frequently. Neonatal characteristics such as birth weight, low APGAR score and admission to neonatal intensive care unit were significantly different between the groups (p < 0.001, for all variables). Total proteinuria at 24 h was found significantly higher in the EOP group than in the LOP group (p = 0.012). CONCLUSION: The results confirmed the opinion that EOP is a distinct and more severe clinical entity than LOP. In particular, higher proteinuria is associated with EOP.

Prenatal determination of the upper lesion level of spina bifida with three-dimensional ultrasound.

INTRODUCTION: To evaluate the role of three-dimensional (3D) sonography in the prenatal detection of the upper pole in fetuses with spina bifida. MATERIAL AND METHODS: Women admitted to a tertiary center with pregnancies with isolated open spina bifida were enrolled in the study. All fetuses had 3D sonography to predict the lesion level. The exact lesion level was ascertained using radiography and/or autopsy following the delivery at term or abortion. RESULTS: Forty-eight cases were eligible for this study. Twenty-eight fetuses were diagnosed in the second trimester and the lesion level was precisely predicted in 24 (86%) of them. In 14 (70%) of the 20 fetuses diagnosed in the last trimester, the level was accurately determined. The remaining 10 fetuses, from both the second and third trimesters, were found to have a lesion level that was within one segment of the predicted lesion level. The correct matching rate was 38/48 (79%), and agreement within one segment was achieved in all cases. DISCUSSION: According to our data, 3D ultrasound is useful for the prenatal determination of lesion level in spina bifida, which is an important prognostic factor.

The reliability of maternal serum triple test in prenatal diagnosis of fetal chromosomal abnormalities of pregnant Turkish women.

AIM: The purpose of this article was to evaluate the reliability of maternal serum triple marker screening of alpha-fetoprotein, human chorionic gonadotropin, and unconjugated estriol for the prenatal diagnosis of fetal chromosomal abnormalities in Turkish pregnant women. METHOD: Medical records were used to analyze indications of amniocentesis and quantitative fluorescent-polymerase chain reaction. Anomaly screening was performed for all patients between 13 and 22 weeks of pregnancy. A total of 1725 pregnancies with chromosomal abnormality risk according to triple test screening were accepted for fetal chromosome analysis and quantitative fluorescent-polymerase chain reaction. RESULTS: Chromosomal aberrations were observed in 56 (3.2%) cases. About 44.6% of the abnormalities detected were numerical aberrations; however, 55.3% of the abnormalities were structural aberrations. Abnormalities detected were inversion of chromosome 9 in 20 cases, trisomy 21 in 14 cases, 46,XX/47,XX, +21 in 1 case, trisomy 18 in 2 cases, trisomy 13 in 1 case, 47,XXY, in 1 case, 45,X, in 1 case, structural abnormalities in 12 cases, and mosaic or tetraploidy in 6 cases. CONCLUSION: Second trimester triple test is an effective screening tool for detecting fetal Down syndrome in Turkish women.

An evaluation of risk factors in pregnant women with Candida vaginitis and the diagnostic value of simultaneous vaginal and rectal sampling.

In this study, we investigated the epidemiological characteristics of VVC among pregnant women. We conducted a prospective survey among 372 pregnant women to investigate the prevalence, clinical forms, etiological agents, and predisposing factors of VVC. In addition, we determined the relationship between vaginal and rectal flora by simultaneously obtaining one high vaginal swab and one rectal swab from each patient using sterile cotton-tipped swabs. Furthermore, we compared the recovery and identification performances of chromID Candida agar to Sabouraud dextrose agar with gentamicin and chloramphenicol. Clinically and mycologically confirmed cases of VVC were detected in 139 (37.4%) and vaginal colonization described in 42 (11.3%) of 372 pregnant women. Rectal cultures were also positive in 98 of the 139 (70.5%) VVC cases. Candida albicans and C. glabrata were identified in vaginal samples in 58.0 versus 19.0% and from rectal samples in 49.0 versus 13.5%, respectively. Increases in gestational week and gravidae were identified to be statistically significant in patients with acute VVC (AVVC) and symptomatic recurrent VVC (RVVC), and asymptomatic RVVC (P = 0.04 and P = 0.03, respectively). In the laboratory diagnosis of VVC, specifically tailored chromogenic media are reliable tools for both the recovery and rapid identification of common Candida spp., particularly C. albicans, as well as for the detection of polyfungal populations in vaginal samples (P > 0.05). In addition, rectal colonization is a common finding in cases of AVVC and symptomatic-RVVC cases and corresponds well with the presence of the same yeast species in the vagina.

Detection of parental origin and cell stage errors of a double nondisjunction in a fetus by QF-PCR.

AIM: To investigate parental origins and cell stage errors of a double nondisjunction in a fetus. METHOD: For the determination of the most common chromosome anomalies, quantitative fluorescent polymerase chain reaction method using short tandem repeat (STR) DNA markers was applied to a fetus with abnormal ultrasonographic findings. Parental origin and cell stage errors of the trisomies were inferred by comparing the inherited STR alleles. Conventional cytogenetic technique was also applied for the confirmation of the aneuploidies. RESULTS: A double nondisjunction including chromosomes 21 and X (48,XXX,+21) was detected prenatally in the fetus. The origin of both chromosomes was maternal, and the errors were in meiosis I for 21 and meiosis II for X. Molecular results were concordant with cytogenetic results. CONCLUSION: Molecular techniques could be useful for the pre- and postnatal diagnosis of the common aneuploidies and determining its parental origin. This kind of study will improve knowledge about the mechanisms of nondisjunction and enable appropriate and rapid genetic counseling.

Cord blood cytokine levels in neonates born to mothers with prolonged premature rupture of membranes and its relationship with morbidity and mortality.

The purpose of this study was to determine cord blood cytokine levels and their relationship with morbidity and mortality in neonates with prolonged, premature rupture of membranes (PPROM). Forty two premature neonates of 29-35 weeks gestational age with PPROM exceeding 24 hours were considered as the PPROM group and simultaneously, 41 premature neonates without PPROM were considered as the control group. All the neonates were admitted to the Neonatology Unit for further evaluation of subsequent complications such as early neonatal sepsis, pneumonia, intraventicular haemorrhage (IVH), respiratory distress syndrome (RDS), necrotizing enterocolitis (NEC) and chronic lung disease (CLD). Cord blood and mothers' blood samples were obtained during delivery in both groups and tested for IL-6, IL-8 and TNF-alpha levels. Twenty one percent of patients with PPROM had histological chorioamnionitis. The risk for developing early neonatal sepsis increased significantly in neonates whose mothers had histological chorioamnionitis (p < 0.05). There was a statistically significant relationship between PPROM and risk of developing NEC (p < 0.05); no significant increase was seen as regards early neonatal sepsis, IVH, RDS, pneumonia, or BPD. The mean IL-8 levels in cord blood and mothers' serum were significantly higher in the PPROM group (p < 0.001, p< 0.005). In addition, IL-6 levels found in mothers' serum were significantly higher than those found in the control group (p < 0.01). However, levels in cord blood were similar (p > 0.05). TNF-alpha levels were similar in both groups (p > 0.05). Neonates who developed NEC had higher IL-8 levels in their cord blood when compared to those without NEC (p < 0.05). In conclusion, the presence of PPROM increases the risk of chorioamnionitis. In addition, PPROM increases the risk of NEC, and patients who developed NEC had significantly higher cord blood IL-8 values. We may conclude that patients with PPROM and higher IL-8 levels in cord blood might be considered as at possible risk of NEC.

Polymorphisms in the tumor necrosis factor-alpha gene in Turkish women with pre-eclampsia and eclampsia.

The genetic background predisposing pregnant women to pre-eclampsia/eclampsia (PE/E) is still unknown. The aim of the current study was to investigate whether there is an association between the TNF-alpha-308 and 850 polymorphisms and PE or eclampsia. In this study, 40 cases of eclampsia, 113 cases of PE and 80 normotensive control cases were genotyped for the TNF-alpha-G-308A and C-850 polymorphisms. At position 308, the replacement of Guanine with Adenosine was denoted as TNF2. We found a significant difference between the TNF2 allele frequencies of the eclamptic, pre-eclamptic and normotensive controls. TNF2 (AA) polymorphism frequency was significantly higher among the eclamptics and pre-eclamptics (control : 5%, PE : 13.3%, E : 12.9%). A significantly different genotype distribution of C-850T polymorphism was observed between the PE/E and control groups, with the frequency of the variant TT genotype being significantly reduced in the preeclamptics (PE : 17% ; E : 17.5%) when compared with the control group (24.3%). We have demonstrated an association between TNF-alpha polymorphisms and pre-eclampsia susceptibility. However, it is not known whether C-850T polymorphism has a functional effect on the TNF-alpha gene. In addition, it was not possible to determine whether this polymorphism promotes the progression from PE to eclampsia because of no statistically significant difference between eclampsia and the controls.

Non-puerperal inversion of the uterus caused by leiomyosarcoma: a case report and clinical management.

Uterine inversion is a rare complication of the postpartum period, but it is an even rarer complication of the non-puerperal period. A 49-year-old nulliparous woman was admitted to the hospital with the following complaints: abnormal vaginal bleeding, pain, anuria and a mass protruding from the vulva. The mass was removed by twisting and a laparotomy was required for massive bleeding due to the inversion. The diagnosis of complete inversion was made during the laparotomy. Total abdominal hysterectomy and bilateral salpingo-oophorectomy was performed and the pathological examination revealed a leiomyosarcoma. Uterine inversion in the non-puerperal period is an extremely rare event and it should be kept in mind that the cause of the inversion may be a malignant disease, like leiomyosarcoma.
