Investigation of the Relationship Between Spiritual Well-Being, Prenatal Stress and Attachment Level of Turkish Women Conceiving Spontaneously or with Assisted Reproductive Techniques.

The aim of the study is to examine the relationship between spiritual well-being, prenatal stress and attachment level of Turkish women conceiving spontaneously or with assisted reproductive techniques (ART). The comparative descriptive study type was conducted between November 2021 and June 2022 with 202 pregnant women, including 87 women conceiving with ART and 115 women conceiving spontaneously, who applied for routine prenatal care checkup in a state hospital in the west of Turkey. Both groups have a high level of spiritual well-being. Pregnant women in the ART group experience higher prenatal distress (9.6% for spontaneous, 12.6% for ART, p = 0.487) and low level of attachment (69.72 ± 7.98 for spontaneous, 66.24 ± 8.88 for ART, p = 0.006) compared to the other group. Additionally, as insufficient partner involvement in the prenatal process increases in pregnant women in both groups, prenatal attachment decreases. It is extremely important that midwives and nurses evaluate the spiritual well-being of pregnant women and provide holistic care in line with their spiritual needs.

Association of increased fetal epicardial fat thickness with maternal pregestational and gestational diabetes.

OBJECTIVE: To evaluate the changes of fetal epicardial fat thickness (EFT) in pregnancies with pregestational diabetes mellitus (PGDM) and gestational diabetes mellitus (GDM) and to identify the diagnostic effectiveness of fetal EFT in differentiating PGDM and GDM from normal pregnancies. METHODS: The study was conducted with pregnant women who admitted to perinatology department between October 2020 and August 2021. Patients were grouped as PGDM (n = 110), GDM (n = 110), and control (n = 110) for comparison of fetal EFT. EFT was measured in all three groups at 29 weeks of gestation. Demographic characteristics and ultrasonographic findings were recorded and compared. RESULTS: The mean fetal EFT was significantly higher in PGDM (1.47 ± 0.083 mm, p < .001) and GDM (1.40 ± 0.082 mm, p < .001) groups compared to control group (1.19 ± 0.049 mm) and was also significantly higher in PGDM group than GDM group (p < .001). Fetal EFT was significantly positively correlated with maternal age, fasting, 1st hour, 2nd hour glucose values, HbA1c, fetal abdominal circumference, and deepest vertical pocket of amniotic fluid (p < .001). Fetal EFT value of 1.3 mm diagnosed PGDM patients with a sensitivity of 97.3% and a specificity of 98.2%. Fetal EFT value of 1.27 mm diagnosed GDM patients with a sensitivity of 94% and a specificity of 95%. CONCLUSIONS: Fetal EFT is greater in pregnancies with diabetes than in normal pregnancies, and also greater in PGDM than in GDM. In addition, fetal EFT is strongly correlated with maternal blood glucose levels in diabetic pregnancies.

Vitamin C (Ascorbic acid) protects from neuropathy caused by cisplatin, through enhanced heat shock protein-70 and reduced oxidant effect.

OBJECTIVE: We aimed to determine whether vitamin C has a protective effect on cisplatin-induced neuropathy in rats. METHODS: In total, 24 rats were included in the study of which 8 rats (no drug administered) were categorized as the control group. The remaining 16 rats were given a total dose of 20 mg/kg cisplatin to induce neuropathy. These drug-administered rats (16 rats) were randomly divided into two groups, namely, group-1 (n=8): cisplatin+saline and group-2 (n=8): cisplatin+vitamin C (500 mg/kg/day). All rats were tested for motor function and electromyographic activity 3 days after cisplatin. Motor performance was evaluated by an inclined-plane test. Compound muscle action potential was evaluated. Plasma malondialdehyde, glutathione, tumor necrosis factor-α, interleukin 6, and sciatic nerve HSP 70 levels were measured. Axon diameter and nerve growth factor expression levels were analyzed. RESULTS: Plasma malondialdehyde, tumor necrosis factor-α, and interleukin 6 levels were higher in the cisplatin+saline group than control group (p<0.001). But vitamin C significantly reduced malondialdehyde and inflammatory cytokine levels when compared with the cisplatin+saline group (p<0.001). Glutathione levels were lower in both cisplatin+saline and cisplatin+vitamin C groups than control group, but vitamin C significantly ameliorated the glutathione levels (p<0.05). Sciatic heat shock protein-70 levels were significantly higher in the cisplatin+vitamin C group than cisplatin+saline group. Compound muscle action potential amplitude and inclined plane test scores were significantly improved in the vitamin C group (p<0.05). Axon diameter and nerve growth factor expression ameliorated with vitamin C (p<0.05). CONCLUSIONS: We demonstrated the ameliorated effects of vitamin C on cisplatin-induced neuropathy through increased heat shock protein-70, nerve growth factor levels, and reduced inflammatory and oxidant effects. The results are promising to improve the neurotoxic effects of cisplatin in cancer patients.

Role of VPAC1 and VPAC2 receptors in the etiology of pregnancy rhinitis: an experimental study in rats / O papel dos receptores VPAC1 e VPAC2 na etiologia da rinite gestacional: um estudo experimental em ratos

Abstract Introduction: Pregnancy rhinitis is a common sex hormone-related otorhinolaryngological disorder. There are some epidemiological and physiological studies on pregnancy rhinitis, but histopathological and biomolecular changes have not been studied thoroughly. Objectives: The receptors VPAC1 and VPAC2 are known for their roles in allergic rhinitis. On the other hand, activation of subclinical allergy has been suggested in the pathophysiology of pregnancy rhinitis. Therefore, we aimed to compare the physiological and gestational pattern of VPAC1 and VPAC2 expression in rat nasal mucosa. Methods: Twenty adult Wister albino female rats were enrolled into the study. Two groups constituted as 10 control (group A) and 10 pregnant (group B) rats. They were fed ad libitum and sheltered at room temperature (22°±2°C). The rats were sacrificed at the 20th day of gestation by intraperitoneal injection of 400mg/kg Na-pentobarbitone. Then, 10 - 15 mL of blood was taken, and samples were reserved for the detection of serum estradiol and progesterone levels by ELISA test. The nasal septum was resected and divided in half for immunohistochemical analyses and real time polymerase chain reaction testing of VPAC1 and VPAC2. Results: VPAC1 and VPAC2 were found to be in all layers of septal specimens, but the immunostaining of surface epithelium was more distinct in specimens of both groups. We demonstrated higher overall staining intensity in the pregnant group. PCR revealed significant increase in expression of VPAC1 (p = 0.023) and VPAC2 (p = 0.021) in pregnant group when compared with control group. In addition, we demonstrated upregulatory effect of estradiol and progesterone on the vasoactive intestinal peptide receptor expression. Conclusions: Gestational up-regulation of nasal VPAC1 and VPAC2 was shown both by PCR and immunohistochemical analysis. These findings support the hypothesis that PR is caused by the activation of subclinical allergy that is present before pregnancy.

Resumo Introdução: A rinite gestacional é um distúrbio comum da otorrinolaringologia relacionado a hormônios sexuais. Existem alguns estudos epidemiológicos e fisiológicos sobre rinite gestacional, mas as alterações histopatológicas e biomoleculares ainda não foram estudadas completamente. Objetivo: Os receptores VPAC1 e VPAC2 são conhecidos por seu papel na rinite alérgica. Por outro lado, a ativação da alergia subclínica tem sido sugerida na fisiopatologia da rinite gestacional. Portanto, objetivamos comparar o padrão fisiológico e gestacional da expressão de VPAC1 e VPAC2 na mucosa nasal de ratos. Método: Vinte ratas fêmeas Wistar albinas adultas foram incluídas no estudo. Os dois grupos foram divididos em 10 ratas; controle (grupo A) e 10 ratas prenhes (grupo B). Elas foram alimentadas ad libitum e abrigadas em temperatura ambiente (22° ±2° C). Sacrificamos as ratas no 20° dia de gestação por injeção intraperitoneal de 400 mg/kg de sódio-pentobarbital. Em seguida, foram coletados 10 a 15 mL de sangue e as amostras foram reservadas para a detecção dos níveis séricos de estradiol e progesterona pelo método Elisa. O septo nasal foi ressecado e dividido em 2 para análises imuno-histoquímicas e testes de reação em cadeia da polimerase em tempo real, RT-PCR, de VPAC1 e VPAC2. Resultados: VPAC1 e VPAC2 foram encontrados em todas as camadas da amostra septal, mas a imunocoloração do epitélio de superfície foi mais distinta nas amostras de ambos os grupos. Demonstramos maior intensidade geral de coloração no grupo gestante. A reação de polimerase em cadeia revelou aumento significante na expressão de VPAC1 (p = 0,023) e VPAC2 (p = 0,021) no grupo gestante quando comparado ao grupo controle. Além disso, demonstramos um efeito up-regulador do estradiol e progesterona na expressão do receptor peptídeo intestinal vasoativo. Conclusão: A up-regulação gestacional dos receptores VPAC1 e VPAC2 nasais foi demonstrada tanto por reação de polimerase em cadeia quanto por análise imuno-histoquímica. Esses achados corroboram a hipótese de que a rinite gestacional é causada pela ativação de alergia subclínica presente antes da gestação.

Protective effects of dichloroacetic acid on endometrial injury and ovarian reserve in an experimental rat model of diabetes mellitus.

AIM: To study (1) ovarian and endometrial damage caused by the hyperglycemia and (2) the effects of dichloroacetic acid (DCA) on follicular reserve and endometrial damage in streptozocin induced diabetic rats. METHODS: This study consisted 24 rats randomly separated into three groups. A diabetes model was achieved in 16 rats experimentally, and normoglycemic eight rats were assigned as control group (Group 1). The rats with diabetes were randomly separated to two groups: 1 mL/kg/day intraperitoneal 0.9% NaCl was given to eight rats as diabetic vehicle (Group 2) and 10 mg/kg/day DCA was given to other eight rats as DCA treated group (Group 3). Hysterectomy with bilateral oophorectomy was performed for histopathological evaluation and blood samples were collected after 4 weeks. RESULTS: Diabetes caused ovarian and endometrial damage (p < 0.0001). Pentraxin-3 (PTX-3), lactic acid, and transforming growth factor-beta (TGF-ß) were higher (p < 0.05, p < 0.05, and p < 0.0001, respectively), whereas anti-Mullerian hormone (AMH) was lower in diabetic rats (p < 0.05). These findings reflected the diabetic damage in the genital tract and diminished ovarian reserve occurred via fibrosis, severe inflammation, and oxidative stress. DCA improved the histopathological fibrosis and degeneration in the ovaries and endometrium (p < 0.05). There was a concominant decrease of TGF-ß and lactic acid levels with DCA treatment (p < 0.05). DCA also improved ovarian reserve with higher AMH levels (p < 0.05). CONCLUSIONS: The several unfavored changes in the endometrium and ovaries due to diabetes have been determined in this present study. DCA might provide the continuity of the endometrial cycle, physiological endometrial structure, ovarian follicular growth, oocyte maturation, and physiological ovarian function by decreasing the lactate levels via inhibiting pyruvate dehydrogenase kinase enzyme.

Impact of Pregnancy and Glucocorticoid Treatment on NF-κB and MUC5AC in Mucosa of Rat Larynx.

OBJECTIVE: The aim of this study is to reveal physiological expression and distribution of nuclear factor-kappa B (NF-κB) and MUC 5 subtype AC (MUC5AC) in rat laryngeal mucosa and to find out the effect of pregnancy and glucocorticoid treatment on these biomolecules. METHODS: This animal experiment was done in Experimental Animals Research and Application Center of Manisa Celal Bayar University in accordance with the accepted policy on the use of animals. A total of 30 young, adult Wister albino female rats were randomized into a control group (group A), a pregnant group (group B), and a steroid administered group (group C). Sacrification was done by injection of sodium-pentobarbitone (400 mg/kg) solution via intraperitoneal route in all groups. Serum estradiole (E2) and progesterone (PG) were determined by enzyme-linked immunosorbent assay. The relative expression and distribution of NF-κB and MUC5AC in laryngeal mucosa was studied both by immunohistochemistry (IHC) and polymerase chain reaction testing. Expression and immunohistochemical localization of NF-κB and MUC5AC was evaluated by light microscopy (Olympus BX41). In statistical analyses; relative expression of NF-κB and MUC5AC were compared on group basis. The effect of E2 and PG levels on these biomolecules was also evaluated. RESULTS: NF-κB was found to be significantly low both in group B (P < 0.05) and C (P < 0.001) when compared with group A, while MUC5AC was found to be significantly high both in group B (P < 0.05) and group C (P < 0.05) when compared with group A. Concerning IHC; NF-κB was found to be expressed in epithelium and lamina propria. MUC5AC was found to be expressed particularly in the epithelial layer in all groups. Statistically significant negative correlation between PG and NF-κB expression (P = 0.048), but no correlation between PG and MUC5AC expression (P = 0.487) were revealed. On the other hand, no correlation was found between E2 and the expression of relevant biomolecules (NF-κB [P = 0.270], MUC5AC [P = 0.829]). We also did found a significant negative correlation between the expression of NF-κB and MUC5AC (P = 0.031). CONCLUSIONS: In this study, the physiological expression of NF-κB and MUC5AC in rat laryngeal mucosa was shown for the first time both by polymerase chain reaction and IHC. The impact of pregnancy and glucocorticoid treatment on the expression and distribution of these biomolecules was also revealed. The expression of NF-κB was found to be decreased while the expression of MUC5AC was found to be increased both by pregnancy and glucocorticoid treatment. The inhibitory effect of serum PG on NF-κB expression in rat laryngeal mucosa was also shown for the first time. The expression of MUC5AC was found to be increased both in pregnant and glucocorticoid administered group. Negative correlation between NF-κB and MUC5AC expression was also revealed in rat larynx for the first time. These findings may partially unclose the histochemical background of voice changes caused by pregnancy and as well as by glucocorticoid treatment.

Termination of pregnancy following a Down Syndrome diagnosis: decision-making process and influential factors in a Muslim but secular country, Turkey.

OBJECTIVES: This study aims to present the termination of pregnancy (TOP) rates and elucidate the decision-making process following a prenatal diagnosis of Trisomy 21 in Turkey. METHODS: This retrospective single-center study was conducted with 146 pregnant women between January 2016 and December 2019 in a tertiary hospital. Data on maternal characteristics, sonographic findings, indications for chromosome analysis, and educational, religious, and economic factors that can influence the parental decision process were collected. RESULTS: The TOP rate of Down syndrome (DS) in our center was 78.8%. We concluded that maternal age, earlier diagnosis, indication for chromosome analysis, and previous pregnancies had no effect on the TOP decision. On the other hand, not having a minor or a major sonographic sign, employed mothers, middle- and high-income families, and families having a secondary or higher education tended to terminate the pregnancy affected by DS at statistically higher rates. CONCLUSIONS: There are many studies worldwide investigating the TOP preferences for DS. However, there is limited data about TOP rates and influential factors affecting the decision-making process in Muslim countries. This study contributes by clarifying the factors in the decision-making process and elucidating perspectives about TOP in a Muslim country with a unique status: Turkey.

Assessment of renal volume by 3D VOCAL Ultrasonography method in late-onset growth-restricted fetuses with normal amniotic fluid index.

OBJECTIVES: The aim of this study was to study renal volumetric alterations and renal artery doppler changes in late-onset fetal growth restricted (FGR) fetuses with normal amniotic fluid compared to healthy pregnancies. MATERIAL AND METHODS: This prospective study was composed of pregnant women with late-onset FGR and a control group of uncomplicated pregnancies within 32-37 weeks of gestation. Following the assessment of umbilical, bilateral uterine, middle cerebral using Doppler Ultrasonography (US), three dimensional (3D) US Virtual Organ Computer-aided Analysis (VOCAL) was executed to calculate bilateral renal volumes. RESULTS: A total of 76 fetuses with FGR and 51 healthy fetuses (control group) were evaluated. Umbilical artery Doppler systole/diastole and Pulsatility index values were found to be significantly different between the two groups (p = 0.001 and p = 0.001, respectively). Middle cerebral, bilateral uterine, and bilateral renal arteries' Doppler indices revealed no difference between the two groups. Right, left, and mean renal volume of the fetuses with FGR were smaller than the control group, and the differences were statistically significant (p = 0.025, p = 0.004, p = 0.004, respectively). Left renal volume was significantly greater than the right renal volume in the control group (p = 0.009). CONCLUSION: Although not accompanied by oligohydramnios, and having similar renal vascular resistance as the control group, renal volumes of fetuses with late-onset FGR were still observed lower than the control group. This difference was explained by not decreased blood flow via redistribution but other mechanisms like glomeruli reduction and glomerular apoptosis.

Maternal serum ADAMTS-9 levels in gestational diabetes: a pilot study.

OBJECTIVE: Gestational diabetes mellitus (GDM) is characterized with insulin resistance which is diagnosed during pregnancy. Although pregnancy is a diabetogenic state, not all women develop GDM. Genetic factors together with enviromental factors cause the maladaptation of maternal pancreas to this diabetogenic state and GDM develops. ADAMTS-9 is a recently recognized molecule whose genetic variants have risk of GDM. Decreased levels have already been shown in fetal membranes. Maternal serum levels of this protein have not been studied yet. We hypothesized that the alteration of ADAMTS-9 expression should cause changes in maternal serum levels which further could help to identify the disease and develop new treatment strategies. MATERIALS AND METHODS: This prospective case-control study is consisted of 27 pregnancies with GDM and 30 healthy singleton pregnancies matched for matenal age, gestational week, and maternal weight. GDM diagnosis was made with 2-h 75 g oral glucose tolerance test. ADAMTS-9 levels were compared between groups. RESULTS: ADAMTS levels were 3.62 ± 0.33 ng/dL (range: 3.04-4.23) in GDM group and 4.65 ± 1.70 ng/dL (range: 3.07-8.21) in control group (p < 0.001). ADAMTS levels were not affected by maternal age, gestational age, and maternal weight. CONCLUSION: ADAMTS-9 levels were significantly lower in GDM pregnancies. This may help to understand the mechanism of GDM pathogenesis. In future, target treatments with ADAMTS proteins may help to improve the severity of diabetes pathogenesis.

Pregnancy rhinitis in Turkish women: Do gestational week, BMI and parity affect nasal congestion?

OBJECTIVE: To determine the cumulative incidence of pregnancy rhinitis along with prevalence in different trimesters and to find out whether gestational age, BMI and parity have any effect on pregnancy related nasal congestion. METHODS: In the prospective protocol at the obstetrics outpatient clinic, 167 pregnant women were enrolled consecutively. According to exclusion criteria, 67 of them were excluded. Visual-Analogue-Scale (VAS), Nasal-Obstructive-Symptom-Evaluation (NOSE) scale and Discharge-Inflammation-Polyps/Oedema (DIP) scoring were utilized for diagnosis of pregnancy rhinitis. Besides, weight, length, age, parity and week of pregnancy were recorded. RESULTS: Total prevalence of pregnancy rhinitis was 17.17% and cumulative incidence was 38.89%. Our study revealed significant relation of NOSE score with both gestational week (r=0.474, p=0.001) and BMI (r=0.301, p=0.003). VAS score was significantly related with gestational week (r=0.409, p=0.001) and BMI (r=0.270, p=0.007). DIP score was found to be correlated only with gestational week (r=0.375, p=0.001). CONCLUSION: Cumulative incidence of pregnancy rhinitis was 38.89%. Nasal congestion was significantly associated with BMI and gestational week. Patients should be informed about unfavorable fetal and maternal outcomes of pregnancy related nasal congestion which is triggered by obesity and excessive weight gain in pregnancy.

Three-dimensional ultrasonographic placental volume in gestational diabetes mellitus.

OBJECTIVES: We aimed to evaluate the placental volume and placental mean gray value in gestational diabetes mellitus (GDM) and healthy placentas using three-dimensional (3D) ultrasound and Virtual Organ Computer-aided AnaLysis (VOCAL). METHODS: This case-control prospective study consisted of 39 singleton pregnancies complicated by GDM and 42 healthy singleton pregnancies matched for gestational age, maternal age and parity. Placental volume and placental volumetric mean gray values were evaluated. The placental volume (cm(3)) was analyzed using the VOCAL imaging analysis program and 3D histogram was used to calculate the volumetric mean gray value (%). RESULTS: Placental volume was significantly larger in GDM (411.59 ± 170.82 versus 343.86 ± 128.94 cm(3); p = 0.046). There was no significant difference in mean gray value between GDM and healthy placentas (36.65 ± 7.02 versus 38.71 ± 7.91, respectively; p = 0.277). Placental volume was significantly correlated with gestational week (r = 0.219, p = 0.035) and parity (r = 0.228, p = 0.048). There was negative significant relation between placental volume and umbilical artery systolic/diastolic ratio, pulsatility index and resistance index (r = -0.278, p = 0.007; r = -0.315, p = 0.002; r = -0.322, p = 0.001, respectively). CONCLUSIONS: Placental volume increases significantly in GDM, whereas mean gray values do not alter significantly. These data may reflect the placental changes in GDM placentas that may help to understand the pathophysiology better.

Normal ranges of biorbital and interorbital distances in healthy Turkish pregnancies at 19-23 weeks of gestation and correlation with craniofacial structures.

OBJECTIVE: We aimed to determine the normal ranges for biorbital (BOD) and interorbital distances (IOD) during the second trimester in Turkish women with normal pregnancies and to assess the correlation between BOD, IOD, and other fetal craniofacial structures and biometric parameters. MATERIAL AND METHODS: Our retrospective study comprised 1328 women with singleton normal pregnancies who had undergone ultrasonography (USG) examinations at 19-23 weeks of gestation in the second trimester screening. The measurements of BOD and IOD were obtained with the coronal section of the fetal face at the plane of orbits. RESULTS: Mean BOD was 3.4±0.33 cm, whereas mean IOD was 1.28±0.24 cm. Correlation analysis revealed that BOD was significantly correlated with IOD, transcerebellar diameter (TCD), cisterna manga (CM), nuchal fold (NF), nasal bone (NB), biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), femur length (FL), and gestational week. There was a significant relation between IOD and the lateral ventricle posterior horn, TCD, CM, NF, NB, BPD, HC, AC, and FL. CONCLUSION: The reference ranges obtained in our study enabled accurate evaluation of BOD and IOD in the second trimester of normal pregnancies. USG detection of fetal orbital biometric anomalies may alert the clinician for different anomalies associated with abnormal development of eye.

Therapeutic effect of sunitinib on diabetes mellitus related ovarian injury: an experimental rat model study.

The aim of our study is to investigate the effect of sunitinib on diabetes mellitus related-ovarian injury and fibrosis in rat models. An experimental diabetes mellitus model was created in 16 rats, and eight rats with normal blood glucose levels were included in control group (Group-1). The diabetic rats were divided into two groups:diabetic control group (water given) - Group-2 and sunitinib treatment group - Group-3. After four weeks, bilateral oophorectomy was performed and ovaries were examined histologically. The groups were compared by Student's t-test, analysis of variance (ANOVA) and Mann-Whitney's U-test. There was a significant increase in no-medication (water given) diabetic rat's ovary (Group-2) in terms of follicular degeneration, stromal degeneration, stromal fibrosis and NF-kappaB immune-expression compared with control group normal rats' ovary (Group-1) (p < 0.0001). Stromal degeneration (p = 0.04), stromal fibrosis (p = 0.01), follicular degeneration (p = 0.02), NF-kappaB immune-expression (p = 0.001) significantly decreased in sunitinib-treated diabetic rat's ovary (Group-3) when compared with no-medication (water given) diabetic rat's ovary (Group-2) (p < 0.05). When we used sunitinib in the treatment of diabetic rats, ovarian injury, fibrosis and NF-kappaB immunoexpression decreased significantly. The effects of sunitinib in rat models give hope to the improved treatment of premature ovarian failure due to diabetes mellitus in humans.

De novo reciprocal translocation t(5;11)(q22;p15) associated with hydrops fetalis (reciprocal translocation and hydrops fetalis).

OBJECTIVE: This is a case of a prenatally diagnosed non-immune hydrops fetalis (NIHF) associated with translocation t(5;11)(q22;p15). An association between NIHF and this translocation has not been reported previously. CASE REPORT: The patient was referred to the perinatology clinic with hydrops fetalis diagnosis at 23 weeks' gestation. We noted that the fetus had bilateral pleural effusion, ascites, widespread subcutaneous edema, membranous ventricular septal defect, hypoplastic fifth finger middle phalanx, clinodactyly, single umbilical artery. We performed cordocentesis. Chromosomal analysis on blood showed a balanced translocation between the long arm of chromosome 5 and the short arm of chromosome 11 with karyotype of 46,XX,t(5;11)(q22;p15). CONCLUSION: We present prenatal diagnosis of a de novo translocation (5;11) in a hydropic fetus with ultrason abnormalities. In our case, karyotype analysis of the fetus, mother and father provided evidence of a de novo translocation, that might explain the NIHF.

Exenatide improves ovarian and endometrial injury and preserves ovarian reserve in streptozocin induced diabetic rats.

We aimed to evaluate: (1) endometrial and ovarian tissue injury caused by the glucose toxicity in diabetic rat model and (2) the effect of GLP-1 analog (exenatide) on endometrial and ovarian diabetes induced injury with emphasizing the underlying mechanism. The study group composed of 24 female rats assigned randomly into 3 groups. Group 1 was the control group (n = 8) and received no treatment. Diabetes was induced by intraperitoneal injection of streptozocin for 16 rats which are further assigned randomly into 2 groups: 1 ml/kg intraperitoneal saline was given to Group-2 (diabetic non-treated control group, 8 rats) and 10 µg/kg/day of intraperitoneal exenatide was given to Group 3 (exenatide treated group, 8 rats) for four weeks. After four weeks, blood samples were collected and hysterectomy with bilateral oophorectomy was performed for histopathological examination. Diabetes caused endometrial and ovarian tissue injury in rats (p < 0.0001). Serum transforming growth factor beta (TGF-ß), malonylaldehyde (MDA), pentraxin-3 (PTX-3) levels were higher in diabetic rats (p < 0.0001), whereas antimullerian hormone (AMH) was lower (p < 0.001). Serum levels of these markers reflected that Diabetes induced injury in the reproductive tract occured via oxidative stress, fibrosis and severe inflammation. Diabetes diminished ovarian reserve. Exenatide treatment improved the histological degeneration and fibrosis in the endometrium and ovary with concomitant decrease in inflammatory and oxidative stress markers (p < 0.05). Exenatide also improved ovarian reserve (p < 0.05). Glucose toxicity occured severely in ovary and endometrium in DM. After exenatide treatment; ovarian and endometrial injury and fibrosis seems to decrease significantly. The effects of exenatide in rat models give hope to prevent the women with DM from premature ovarian failure and endometrial dysfunction.

Foetal axillary lymphangioma with ipsilateral pes equinovarus: pitfalls in sonographic differential diagnosis (axillary lymphangioma & pes equinovarus).

Lymphangiomas are rare congenital malformations of the lymphatic system. Despite the benign histology, they are likely to grow rapidly and invade the surrounding tissues. In contrast to the cystic hygromas, lymphangiomas at the axillary region tend to have normal karyotype. However, associated hydrops makes the prognosis poor. Due to isolated few cases in the literature, the true incidence of foetal axillary lymphangiomas is not known. We present here a pre-natal ultrasonographic diagnosis of a 15-week foetus with rapidly growing axillary lymphangioma with ipsilateral foot abnormality which had normal karyotype.

The assessment of placental volume and mean gray value in preeclamptic placentas by using three-dimensional ultrasonography.

OBJECTIVES: We aimed to evaluate the placental volume and placental mean gray value in preeclampsia and healthy placentas by using three-dimensional (3D) ultrasonography and Virtual Organ Computer-aided AnaLysis (VOCAL). METHODS: This case-control prospective study consisted of 27 singleton pregnancies complicated by preeclampsia and 54 healthy singleton pregnancies matched for gestational age, maternal age and parity. Placental volume and placental volumetric mean gray values were evaluated. The placental volume (cm(3)) was analyzed using the VOCAL imaging program, and 3D histogram was used to calculate the volumetric mean gray value (%). RESULTS: Preeclamptic and control group consisted of 27 (mean age: 28.90 ± 5.95 years, mean gestation: 32.0 ± 4.55 weeks) and 54 (mean age: 29.48 ± 5.78 years, mean gestation: 32.61 ± 4.23 weeks) singleton pregnancies, respectively. Placental volume was significantly smaller in preeclampsia (250.62 ± 91.69 versus 370.98 ± 167.82 cm(3); p = 0.001). Volumetric mean gray value of the placenta was significantly higher in preeclampsia (38.24 ± 8.41 versus 33.50 ± 8.90%; p = 0.043). Placental volume was significantly correlated with the estimated fetal weight (r = 0.319; p = 0.003). There was negative significant relation between placental volume and umbilical artery pulsatility index, resistance index and systolic/diastolic ratio (r = -0.244, p = 0.024; r = -0.283, p = 0.005; r = -0.241, p = 0.024, respectively). CONCLUSIONS: Placental volume diminishes significantly in preeclampsia, whereas volumetric mean gray values increases. This may reflect the early alterations in preeclamptic placentas, which may help to understand the pathophysiology better.
