Isolated Aberrant Right Subclavian Artery and Trisomy 21 Case

Abnormal right subclavian artery (ARSA) is the most common anomaly of the aortic arch with a rate of 0.5-1.4%. Normally, three vessels arises from the aortic arch, while four vessels arise in ARSA. ARSA leaves the distal of the aortic arch and passes behind the esophagus and trachea. It is also called the abnormal retroesophageal right subclavian artery. It is generally an asymptomatic benign finding, but it can cause esophageal compression causing dysphagia. In this article, an isolated ARSA and trisomy 21 case referred to our clinic in the second trimester of pregnancy and detected ultrasonographically is presented

Wpływ rodności na kształt fali przepływu Dopplera w pierwszym trymestrze pojedynczej ciąży niskiego ryzyka

Objectives: The aim of the study was to evaluate the effect of parity on uteroplacental blood flow during the first trimester in low-risk singleton pregnancies. Materials and methods: Uterine artery Doppler examinations were performed in 190 singleton pregnancies between 11-14 gestational weeks. Twenty-five pregnancies were excluded from the study due to history of preeclampsia, diabetes mellitus or inherited thrombophilia. A total of 165 low-risk singleton pregnancies were included in the study. Mean uterine artery pulsatility index (PI) was recorded and compared between nulliparous and multiparous women. The relation between maternal age, gestational week, maternal weight, parity, biochemical markers and abnormal uterine artery Doppler flows was evaluated. T-test and logistic regression analyses were used for the statistical analysis. Results: A total of 165 singleton pregnancies without any risk factors for uteroplacental insufficiency were included in the study. Of them, 58 (36.7%) were nulliparous and 107 (63.3%) were parous. Correlation analysis revealed that the uterine artery pulsatility indices during the first trimester were not affected by maternal age and parity. Conclusions: Mean uterine artery pulsatility indices are not different in nulliparous and multiparous low risk pregnancies at 11-14 weeks of gestation.Cel: Celem badania była ocena wpływu rodności na przepływ maciczno-łożyskowy w pierwszym trymestrze pojedynczej ciąży niskiego ryzyka. Materiał i metoda: Przepływ w tętnicy macicznej zbadano w 190 pojedynczych ciążach w 11-14 tygodniu. Z analizy wyłączono 25 ciąż z powodu dodatniego wywiadu w kierunku stanu przedrzucawkowego, cukrzycy lub wrodzonej trombofilii. Ostatecznie do badania włączono 165 pojedynczych ciąż niskiego ryzyka. Zmierzono średni indeks pulsacji w tętnicy macicznej (PI), który porównano pomiędzy nieródkami i wieloródkami. Oceniono również związek pomiędzy wiekiem matki, wiekiem ciążowym, masą matki, liczbą porodów, markerami biochemicznymi a nieprawidłowym przepływem w tętnicach macicznych. T-test i regresji logistycznej zostały wykorzystane do analizy statystycznej. Wyniki: Do badania włączono 165 pojedynczych ciąż bez czynników ryzyka niewydolności maciczno-łożyskowej. Z tej grupy, 58 (36,7%) kobiet było nieródkami a 107 (63,3%) wieloródkami. Analiza statystyczna wykazała brak związku pomiędzy indeksem pulsacji w pierwszym trymestrze ciąży a wiekiem matki i rodnością. Wnioski: Średni indeks pulsacji w tętnicy macicznej nie różni się pomiędzy nieródkami a wieloródkami w ciąży niskiego ryzyka w 11-14 tygodniu

Abnormal Elevated CA 19-9 in the Dermoid Cyst: A Sign of the Ovarian Torsion?

Dermoid cyst is the most common germ cell tumor of the ovary containing various tissue elements. Ovarian torsion is a common complication of which ultrasonographic diagnosis is confusing. We report here a 14-year-old adolescent with painless torsion of the ovary including dermoid cyst and with abnormal elevated CA 19-9 serum levels. Elevated CA 19-9 level may be related to ovarian torsion and may predict the extent of tissue necrosis

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

WOS: 000358467100006PubMed ID: 25366063We 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 mu g/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-beta), 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

Ovarian failure in diabetic rat model: Nuclear factor-kappaB, oxidative stress, and pentraxin-3

WOS: 000348753800012PubMed ID: 25510691Objective: The aim of the present study was to investigate the effects of diabetes mellitus (DM) on ovarian reserve and injury by considering laboratory and histopathological parameters in rat models. Materials and methods: An experimental DM model was created in 16 rats. Eight rats with normal blood glucose levels were included in the control group. Diabetic rats were divided randomly into two groups: nontreated and resveratrol-treated groups. Histopathological examination and nuclear factor (NF)-kappa B immunoexpression level determination were performed. Plasma malondialdehyde, glutathione, pentraxin-3, and anti-Mullerian hormone levels were measured. Relations between the variables were compared by Student t test, analysis of variance, and Mann-Whitney U and X-2 tests. Results: We found statistically significantly lower glutathione and anti-Mullerian hormone levels, and higher malondialdehyde and pentraxin-3 levels in nontreated diabetic group when compared with the control and resveratrol-treated diabetic groups. Stromal degeneration, follicle degeneration. stromal fibrosis scores, and NF-kappa B immunoexpression levels were significantly higher in nontreated diabetic rats. Primordial and primary follicle counts were significantly lower in the nontreated diabetic group when compared with the control and resveratrol-treated groups. There was no statistically significant difference in secondary and tertiary follicles between these groups. Conclusion: These findings provide strong evidence that the ovarian follicle pool in nontreated diabetic rats is affected in the early stages of the follicle development process. We precluded negative effects of DM on ovaries by inhibiting the NF-kappa B pathway with resveratrol. We thought that the NF-kappa B pathway plays a role in the pathophysiology of ovarian failure in diabetic rats. Further studies should evaluate this precise mechanism that leads to a decline in the anti-Mullerian hormone levels. In addition, the relationship between this abnormality and reproductive function in diabetic patients should be analyzed further. Copyright (C) 2014, Taiwan Association of Obstetrics & Gynecology.

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

WOS: 000358972300011PubMed ID: 25703256The 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
