Plasma L-carnitine levels of obese and non-obese polycystic ovary syndrome patients.

It is well-known that plasma L-carnitine concentrations are significantly decreased in obese individuals. A study showed that L-carnitine concentrations are significantly lower in lean PCOS patients than in lean healthy women. Thus, it has been suggested that lowered L-carnitine is associated with PCOS. This study also showed that the women with PCOS had significantly lower L-carnitine levels than those of the healthy controls. In addition, this study hypothesised that low L-carnitine levels in PCOS patients were associated with obesity and/or insulin resistance. Moreover, plasma L-carnitine concentrations were found to be statistically similar in PCOS patients and healthy controls, when controlled for obesity. This study implied that L-carnitine could be used as an adjunctive therapy in the management of insulin resistance or obesity in women who have PCOS. Further research might be planned to clarify the clinical effects of L-carnitine administration in PCOS patients with insulin resistance and/or obesity.

Heart rate variability and heart rate turbulence in patients with polycystic ovary syndrome.

OBJECTIVE: Cardiac autonomic dysfunction may develop in patients with polycystic ovary syndrome (PCOS). Heart rate variability (HRV) and heart rate turbulence (HRT) are used in assessing cardiac autonomic functions. The goal of this study was to compare the cardiac autonomic functions in patients with PCOS and healthy controls. To our knowledge, this is the first study evaluating cardiac autonomic functions in patients with PCOS with respect to both HRV and HRT. METHODS: Twenty-three patients with PCOS (mean age 22.8±3.9 years) and 25 healthy female volunteers who were matched for age and body mass index (BMI) (mean age 23.5±6.2 years) were enrolled in this as case-control study. Twenty-four hour ambulatory electrocardiogram recordings of all participants were taken using Pathfinder software. The time domain parameters of HRV and HRT, including turbulence onset (TO) and turbulence slope, were calculated. Diagnosis of PCOS was made with physical and laboratory findings of hirsutism or biochemical hyperandrogenism and chronic anovulation. Diabetes mellitus, other hormon disorders or hormon therapy, pregnancy, atrial fibrilation, obesite, chronic diseases, disorders of the autonomic nervous system, a history of drug use affecting the autonomic nervous system were excluded. RESULTS: There were no significant differences in HRV and HRT parameters between the two groups. Cardiovascular risk factors, such as BMI, blood pressure, fasting blood glucose, and lipid parameters, were also similar. Triangular index measure of HRV was negatively correlated with high density lipoprotein cholesterol levels (r=-0.47, p<0.05), while age and BMI were significantly correlated with TO (r=0.31 and 0.47, respectively; p<0.05 for all). CONCLUSION: Cardiac autonomic functions were not found to be altered in patients with PCOS in comparison with healthy controls. These results may be explained with the absence of concomitant cardiovascular risk factors with the patients being in the early stage of the disease.

Comparison of four different pain relief methods during hysterosalpingography: a randomized controlled study.

BACKGROUND: Hysterosalpingography (HSG) is the most commonly used method for evaluating the anatomy and patency of the uterine cavity and fallopian tubes, and is an important tool in the evaluation of infertility. The most frequent side effect is the pain associated with the procedure. OBJECTIVES: To evaluate four analgesic methods to determine the most useful method for reducing discomfort associated with HSG. METHODS: In the present prospective study, 75 patients undergoing HSG for evaluation of infertility were randomly assigned to four groups: 550 mg of a nonsteroidal anti-inflammatory drug (NSAID) (group 1); 550 mg NSAID + paracervical block (group 2); 550 mg NSAID + paracervical analgesic cream (group 3); or 550 mg NSAID + intrauterine analgesic instillation (group 4). A visual analogue scale was used to assess the pain perception at five predefined steps. RESULTS: Instillation of the liquids used for HSG was found to be the most painful step of HSG, and this step was where the only significant difference among groups was observed. When comparing visual analogue scale scores, group 2 and group 3 reported significantly less pain than the other groups. Group 1 reported significantly higher mean (± SD) scores (7.2 ± 1.6) compared with groups 2 and 3 (4.7 ± 2.5 and 3.8 ± 2.4, respectively) (P<0.001). In addition, group 2 reported significantly less pain than group 4 (4. 7 ± 2.5 versus 6.7 ± 1.8, respectively) (P<0.02). CONCLUSIONS: For effective pain relief during HSG, in addition to 550 mg NSAID, local application of lidocaine cream to the posterior fornix of the cervix uteri and paracervical lidocaine injection into the cervix uteri appear to be the most effective methods.

Is abnormal glucose metabolism during pregnancy related to endothelial dysfunction?

OBJECTIVE: Endothelial dysfunction is an independent risk factor for cardiovascular events. We aimed to investigate the relationship between endothelial dysfunction and gestational diabetes mellitus and impaired glucose tolerance. METHODS: Pregnant women who had impaired glucose metabolism in the 75-g oral glucose tolerance test (OGTT) and their age- and body mass index-matched controls were included in the study and assessed for flow-mediated vasodilatation to evaluate endothelial dysfunction. RESULTS: A total of 51 patients participated in the study. There were 20 patients in the control group, 13 in the impaired glucose tolerance group and 18 in the gestational diabetes mellitus group. Flow-mediated vasodilatation measured at the 60th and 120th seconds were significantly lower in the impaired glucose tolerance and gestational diabetes mellitus groups than in the control group (8.5 ± 5.7 and 8.9 ± 6.5 versus 14.9 ± 9.0, p=0.022 and 6.2 ± 6.7 and 5.2 ± 5.0 versus 12.0 ± 8.3, p=0.011, respectively). CONCLUSIONS: Patients with gestational diabetes mellitus and impaired glucose tolerance have impaired endothelial dysfunction. Delivery might have protective effects on endothelial functions. The significance of impaired endothelial dysfunction for pregnant women must be investigated, and if needed, lifestyle changes might be suggested, according to the determined importance of the endothelial dysfunction.

L-Carnitine: a new insight into the pathogenesis of endometrial cancer.

OBJECTIVES: The present study aims to specify the role of L-carnitine in the pathogenesis of endometrial cancer by comparing the serum total L-carnitine levels of endometrial cancer patients with those of healthy women. METHODS: Serum total L-carnitine concentrations were measured in patients with endometrioid-type endometrial cancer (n = 20) and healthy controls (n = 20) who were matched with respect to age and body mass index (BMI). RESULTS: Stage I endometrial cancer was diagnosed in 12 women (60.0%) whereas three women (15.0%) had stage II disease, three women (15.0%) had stage III disease and two women (10.0%) had stage IV disease. The healthy controls and endometrial cancer patients were statistically similar in aspect of age, gravidity, parity, BMI, waist-to-thigh ratio, waist-to-hip ratio, menopause, complete blood count parameters, and serum biochemistry. Serum total L-carnitine levels of women with endometrial cancer were significantly lower than those of healthy women (respectively, 5,519.4 ± 2,712.5 vs 7,940.8 ± 3,566.6 ng/dl, p = 0.021). Moreover, serum total L-carnitine levels decreased significantly and progressively with advancing stage (stage I vs II vs III vs IV; 6,294.0 ± 2,885.1 vs 5,800.0 ± 441.2 vs 4,016.0 ± 2,833.3 vs 2,560.0 ± 67.9 ng/dl; p = 0.021). CONCLUSIONS: This is the first study to hypothesize that L-carnitine deficiency participates in the pathogenesis of endometrial cancer by means of a mechanism which is unrelated with obesity and increased amount of fat in human body.

Could mean platelet volume in late first trimester of pregnancy predict intrauterine growth restriction and pre-eclampsia?

AIM: The present study aims to determine whether mean platelet volume (MPV) specified in late first trimester of pregnancy can be used to predict pre-eclampsia and intrauterine growth restriction (IUGR). METHODS: This study prospectively reviews 200 healthy women with 11-14-week-old pregnancies. RESULTS: Average pregnancy-associated plasma protein-A (PAPP-A) multiples of the median (MoM) value was significantly lower and MPV was significantly higher in pre-eclamptic pregnancies (P = 0.001 for both). MPV values of 10.5 fl or more can predict pre-eclampsia with 66.7% sensitivity and 63.8% specificity. The combination of MPV of 10.5 fl or more and PAPP-A MoM of 0.33 or less can predict pre-eclampsia with 75% sensitivity and 70.0% specificity. MPV values of 10.5 fl or more can predict IUGR with 82.4% sensitivity and 60.0% specificity. The combination of MPV of 10.5 fl or more and PAPP-A MoM of 0.33 or less can predict IUGR with 85.3% sensitivity and 62.0% specificity. CONCLUSION: Increased MPV reflects enhanced platelet activation which may be caused by impairment in uteroplacental circulation. When MPV of 10.1 or more and PAPP-A MoM of 0.33 or less are combined as a threshold, the pregnancies that are destined to develop IUGR and pre-eclampsia can be predicted with considerably high sensitivity and specificity. The MPV and PAPP-A combination can be addressed as a useful biochemical tool for the prediction of IUGR and pre-eclampsia in late first trimester.

Is three-dimensional prenatal ultrasound necessary: pregnant women's point of view.

OBJECTIVES: The role and applicability of three-dimensional ultrasound (3D-US) in perinatology has been repeatedly discussed in the literature. Regardless, our knowledge about patient expectations remains limited. We aimed at determining the expectations, perception and knowledge of pregnant women about 3D-US. MATERIAL AND METHODS: Upon admission to the labor unit, the women filled out a questionnaire, with the help of a doctor investigating sociodemographic data, pregnancy and delivery history previous experiences and expectations for US imaging. RESULTS: A total of 644 pregnant women were included in the study Respondents declared that approximately 70% of all kinds of structural abnormalities could be detected by 3D-US and estimated its reliability at nearly 70%. While 60% of the participants underwent 3D-US, 70% of them believed that every pregnant woman should undergo such test. Also, 457 (70.9%) of the participants were of the opinion that every pregnant woman must undergo 3D-US imaging, whereas 173 (26.8%) did not think 3D-US imaging was necessary CONCLUSIONS: To the best of our knowledge, this has been the first study on patient opinions regarding the need for 3D-US imaging during pregnancy Although the participants were not certain about the harmful effects of 3D-US, the majority believed that it was necessary for every pregnant woman to undergo such testing. Obviously patients must be instructed on the limitations of US imaging before the examination to clarify any misunderstandings about the possibilities such a technique may offer

Maternal blood pressure and dominant sleeping position may affect placental localization.

OBJECTIVE: This study investigates whether maternal socio-demographic and clinical characteristics influence the site of placental implantation so that placental localization and associated abnormalities can be predicted. METHODS: This study reviews 500 healthy women with singleton pregnancy that were consecutively admitted to the study center and eventually delivered healthy newborns. RESULTS: The most frequently observed sites of placentation were anterior uterine wall (53.2%), posterior uterine wall (28.8%), lateral uterine walls (10.0%) and uterine fundus (8.0%), respectively. The women with fundal placentation had significantly higher systolic and diastolic blood pressures (p = 0.044 and p = 0.040, respectively). Supine sleeping position was more frequent in women with anterior placenta and (OR: 11.568, 95% CI: 2.720-49.193) and prone sleeping position was more frequent in women with posterior placenta (OR: 15.449, 95% CI: 2.151-52.978) (p = 0.001). The women who favored to sleep in right lateral position were more likely to have lateral placentation, while the women who used to sleep in left lateral position were more likely to have fundal placentation (p = 0.001). CONCLUSIONS: Sleeping position in early pregnancy may influence placental implantation site. The probable mechanism may refer to the alterations in uterine perfusion which is induced by the change in systemic blood pressure and dominant sleeping position.

Transcutaneous electrical nerve stimulation (TENS) for pain control after vaginal delivery and cesarean section.

OBJECTIVE: The present study aims to determine the efficiency and reliability of transcutaneous electrical nerve stimulation (TENS) in the management of pain related with uterine contractions after vaginal delivery and the pain related with both abdominal incision uterine contractions after cesarean section. METHODS: A hundred healthy women who underwent cesarean section under general anesthesia were randomly assigned to the placebo group (Group 1) or the TENS group (Group 2), while 100 women who delivered by vaginal route without episiotomy were randomized into the placebo group (Group 3) or the TENS group (Group 4). RESULTS: The patients in Group 2 had statistically lower visual analog scale (VAS) and verbal numerical scale (VNS) scores than the patients in Group 1 (p < 0.001 for both). The patients in Group 4 had statistically lower VAS and VNS scores than the patients in Group 3 (p = 0.022 and p = 0.005, respectively). The analgesic requirement at the eighth hour of cesarean section was significantly lower in the patients who were treated with TENS (p = 0.006). The need for analgesics at the eighth hour of vaginal delivery was statistically similar in the patients who were treated with TENS and the patients who received placebo (p = 0.830). CONCLUSION: TENS is an effective, reliable, practical and easily available modality of treatment for postpartum pain.

Lowered serum total L-carnitine levels are associated with obesity at term pregnancy.

OBJECTIVE: This study aims to compare the serum total l-carnitine concentrations of obese and non-obese pregnant women and to identify the role of L-carnitine in both maternal and fetal weight gain during pregnancy. METHOD: This study reviews 118 healthy women with singleton term pregnancy (≥37 weeks). The characteristics of the recruited subjects were analyzed according to their pre-pregnancy body mass index (BMI). RESULTS: The women with pre-pregnancy BMI < 18.5 kg/m(2) had significantly higher serum L-carnitine levels whereas the women with BMI > 29.9 kg/m(2) at term pregnancy had significantly lower serum l-carnitine levels (p = 0.001 for both). The neonates born to women with BMI > 29.9 kg/m(2) at term pregnancy had significantly longer height and wider head circumference (p = 0.001 for both). Serum total L-carnitine levels correlated significantly and negatively with pre-pregnancy body weight, pre-pregnancy BMI, pregnancy body weight, pregnancy BMI and serum triglyceride levels (r = -0.397, p = 0.001; r = -0.357, p = 0.001; r = -0.460, p = 0.001; r = -0.463, p = 0.001 and r = -0.216, p = 0.019, respectively). There was a significant and positive correlation between L-carnitine and HDL values (r = 0.243, p = 0.008). CONCLUSIONS: The crucial role of L-carnitine in pregnancy metabolism suggests that nutritional supplementation of this amino acid can be offered to women who are either overweight or obese at the beginning of the pregnancy.

Awareness and use of folic acid among reproductive age and pregnant women.

OBJECTIVE: Folic acid supplementation during the pre-conception period and first trimester of pregnancy reduces the incidence of neural tube defects (NTDs). In this study, our aim is to investigate knowledge and use of folic acid among women attending our clinic. MATERIAL AND METHODS: Between January 2012 and June 2012, 817 participants, consisting of 345 pregnant and 472 non-pregnant women, were enrolled in this survey. A questionnaire including socio-demographic information, knowledge and use of folic acid was applied. RESULTS: 48.2% of participants were aware of folic acid for the prevention of congenital anomalies. Knowledge and use of folic acid increase with socio-economic status and educational level. Participants who were already knowledgeable about folic acid cited health care professionals as common sources of information. Although 88.2% of the pregnancies were planned among the currently pregnant women, only 14.2% of them stated that they had used folic acid in the pre-conception period. The use of folic acid during the first trimester among pregnant women was 48.6%. Furthermore, 18.4% of participants had not used folic acid and 29.3% of them had not remembered whether they had or not. Even though 94.4% of health care professionals had heard about folic acid, 28.3% reported that they had used folic acid before pregnancy. CONCLUSION: It is thought that there is a relatively high incidence of NTD in Turkey, which is due to inadequate information about NTDs and the use of folic acid. Primarily health care professionals such as midwives, nurses and family physicians should aim to inform all reproductive age women about folic acid for the prevention of NTDs, who should be encouraged to take the supplement when planning pregnancy.

Cystic lymphangiomatosis with severe intra-abdominal bleeding in a newborn: case report.

We report the case of a newborn girl with intestinal cystic lymphangiomatosis who presented with abdominal distension and intra-abdominal bleeding following a prenatal ultrasound diagnosis of intestinal anomaly. Postnatal abdominal ultrasound revealed disseminated submucosal and intramural cystic dilatations of various sizes in the bowel and intestinal lymphangiomatosis was diagnosed. The presence of severe bleeding diathesis and widespread disease led to conservative treatment. The patient died on postnatal day 7 and postmortem examination confirmed cystic lymphangiomatosis. Detection of intestinal hyperechogenicity and/or dilatation in prenatal ultrasonography and the persistence of these findings during pregnancy are suggestive for pathologies such as meconium ileus, meconium peritonitis, and intestinal atresia. Although rare, intestinal lymphangiomatosis should be kept in mind in patients whose prenatal sonographic findings persist until birth.

Very rare cause of vaginal mass in pregnancy: cavernous hemangioma.

Vaginal cavernous hemangioma is a considerably rare condition during pregnancy. There has only been one reported case to date. A multiparous, 24-year-old woman in the 32nd week of pregnancy was admitted with a mass prolapsed from the vagina, which had suddenly increased in size over the previous few days. A necrotic mass obstructing the vaginal canal and originating from the posterior wall was observed in a pelvic physical examination and carefully excised. The patient had contractions after the intervention and was administered tocolytic treatment with bed-rest and fluids. Her obstetric clinical status was stable after treatment and she gave birth without complication at 37 weeks and 5 days from the vaginal canal. The main approach to these very rare tumors of pregnancy, especially in the presence of necrosis, infection and/or obstruction, should be excision. But the potential for increased blood loss that may occur due to the hypervascular structure of the tumor should be taken into account.

Efficacy of transcutaneous electrical nerve stimulation for pain relief in women undergoing office endometrial biopsy.

AIM: To evaluate the efficacy of transcutaneous electrical nerve stimulation (TENS) for decreasing pain related with office endometrial biopsy. METHODS: In this prospective study, 65 women undergoing office endometrial biopsy were randomly allocated to receive 550 mg oral naproxen sodium plus active TENS (Group I, n = 33) or 550 mg oral naproxen sodium plus placebo TENS (Group II, n = 32). The intensity of pain perceived by the patients was measured using a 10-cm visual analog scale (VAS) before insertion of the speculum, when the cervix grasped, immediately after biopsy, and 15 min after the procedure. The effect of anxiety (Spielberger's state anxiety inventory) on pain scores was also investigated. RESULTS: There were no statistical significant differences between groups in age, weight, body mass index, gravidity, parity, education, and menopausal status (p > 0.05). The pain scores before insertion of the speculum, when the cervix grasped, and immediately after biopsy were similar in both groups (p > 0.05). But at 15 min after the procedure, there was a significant reduction of the mean VAS pain score in naproxen sodium plus TENS group, compared with the naproxen sodium plus placebo TENS group (0.14 ± 0.47, 1.44 ± 1.37, respectively, p < 0.0001). The mean anxiety scores were 48.19 ± 6.71 and 45.85 ± 6.22 in Group I and Group II, respectively. We did not find any significant correlation between anxiety and VAS pain scores (p > 0.05). CONCLUSIONS: TENS appears to be successful in decreasing pain only after the procedure undergoing office endometrial biopsy. It can be used as a simple, cheap, safe, and effective pain relief method.

Evaluation of amniotic fluid as a skin graft storage media compared with RPMI and saline.

We aimed to assess and compare the histological changes of grafts stored in Roswell Park Memorial Institute-1640 solution (RPMI), amniotic fluid (AF), and saline. Amniotic fluid which has abundant nutrients, proteins, and growth factors, and antimicrobial features may be an easily achievable and cheap alternative for the short term preservation of skin grafts. Discarded surgical skin pieces obtained from 15 trauma patients were divided into three groups as RPMI, AF, and saline. The specimens were evaluated at days 7, 14, 21, and 28 for histological alterations by a 3-point scoring scale. Histological scores in the grafts stored in amniotic fluid and RPMI were found significantly lower than those stored in saline (p<0.01). No significant difference was detected between AF and RPMI stored grafts. AF may be a good alternative for skin graft preservation as demonstrated by histological changes. New studies with multiple AF donators and repeated experiments will be worthwhile. Besides, restrictions of some ethical and legal issues for AF use should be solved.

Maternal and fetal leptin and ghrelin levels: relationship with fetal growth.

PURPOSE: In our study, we investigated the influence of plasma levels ghrelin, leptin and other metabolic hormones (ILGF-1 and ILGF-2) in pregnants in regulating fetal body weight and mode of delivery. METHODS: A total of 36 appropriately healthy pregnants 19-36-year-old were involved in the study. Demographic characteristics, serum ghrelin, leptin, IGF-1 and IGF-2 levels of the pregnants were studied. RESULTS: Plasma ghrelin and leptin levels did not differ significantly among trimesters and delivery, in contrast to IGF-I and IGF-II concentrations were significantly higher in the first half of the pregnancy (P < 0.05). Serum leptin was significantly associated with mode of delivery (r = 0.231; P = 0.008), BMI (r = 0.462; P = 0.004). CONCLUSION: Metabolic factors are associated with fetal growth, but in AGA babies, there were no differences between any parameter and clinical factor.

Assessment of pulmonary functions and anthropometric measurements in women with polycystic ovary syndrome.

OBJECTIVES: The aims of this study were to compare pulmonary function tests of patients with polycystic ovary syndrome (PCOS) versus healthy women, and to investigate correlations between pulmonary function tests and anthropometric measurements of them. MATERIALS AND METHODS: A total of 31 women with PCOS and 29 controls matched for age and body mass index (BMI) were enrolled into the study. Pulmonary function tests were performed with spirometer. Body fat percentage was calculated from the skinfold thicknesses using the formula. Biacromial, chest antero-posterior and lateral diameter measurements were carried out with anthropometric set. RESULTS: There were no significant differences between patients with PCOS and healthy controls in the pulmonary function tests, body fat %, chest and abdomen region anthropometric measurements. There were moderate negative correlations only between forced expiratory volume per 1 s and BMI, abdomen circumference, body fat percentage in patients with PCOS. In the control group, however, there were moderate or strong negative correlations between anthropometric measurements (BMI, body fat percentage, abdominal circumference, chest lateral diameter) and at least three different pulmonary function tests. CONCLUSION: These results suggest that the upper body anthropometry and respiratory function relations might have impaired in patients with PCOS. We think that this situation might support the increased tendency for poor health status in patients with PCOS.

Histological assessment of skin grafts stored in amniotic fluid and saline.

We investigated the efficacy of amniotic fluid as a substance in which to store grafts; it is rich in nutrients, proteins, and growth factors, and has well-known antimicrobial features. We compared it with the widely-used and practical saline. Split-thickness grafts 4 × 4 cm were prepared from the back of 20 rats and divided into four groups (n = 5 each). The rolled grafts were wrapped in gauze dampened with saline or amniotic fluid and placed into refrigerators in sterile containers for storage. On days 7, 14, 21, and 28, histological examinations were made. A semiquantitative evaluation of the histological damage to the skin was made by scoring its degree of severity. Compared with saline, histological scores in the grafts stored in amniotic fluid were found to be significantly lower on the 14th, 21st, and 28th days (p values on days 14, 21, and 28; cell swelling: 0.014, 0.006, and 0.005, respectively; nuclear swelling: 0.003, 0.006, and 0.007, respectively; nuclear pleomorphism: 0.004, 0.005, and 0.003, respectively; nuclear haloes: 0.015, 0.005, and 0.005, respectively; nuclear pyknosis: 0.003, 0.005, and 0.003, respectively; dermo-epidermal clefting: 0.005, 0.003, and 0.003, respectively; eosinophilia and mitosis: 0.003, 0.006, and 0.004, respectively; dermal collagen: 0.003, 0.003, and 0.003, respectively). Amniotic fluid maintained preservation better for skin grafts than saline. Comparison with other modern storage media would be beneficial.

Protective effect of aprotinin on ischemia-reperfusion injury in rat ovary.

AIM: We investigated the effects of aprotinin on reperfusion injury in a controlled experimental rat torsion-detorsion model. METHODS: Thirty-two female Sprague-Dawley rats were divided into four groups. Sham operation was performed in group I; in group II only ovarian torsion was performed. In group III, torsion-detorsion was performed, plus 3 mL/kg saline was injected i.v. 30 min before detorsion. In group IV, torsion-detorsion was performed, plus aprotinin (30,000 KIU/kg) was injected 30 min before detorsion. Rats in the torsion group were killed after 360 degrees clockwise adnexial torsion for 3 h, and the ovaries were harvested. After 3 h of adnexial detorsion, the rats in the saline and aprotinin groups were killed and the adnexa were surgically removed. RESULTS: Ovarian tissue damage scores were significantly different among groups. Ovarian tissue and serum malondialdehyde levels in group III were significantly higher than those of groups I and IV (P<0.05). The serum levels of superoxide dismutase in group III were significantly lower than those of groups I and IV (P=0.01). Tissue and serum xanthine oxidase, nitric oxide, and tissue superoxide dismutase levels were comparable among groups (P>0.05). CONCLUSIONS: Aprotinin attenuates ischemia-reperfusion injury in a rat adnexial torsion-detorsion model.

Prenatal diagnosis of a fetal intracranial immature teratoma.

Congenital intracranial teratoma is a rare disease. A fetus with a congenital intracranial teratoma presenting with a hydrocephalus at 27 weeks' gestation is presented. Prenatal ultrasonography and fetal magnetic resonance imaging demonstrated a huge, heterogeneous intracranial mass including the infra- and supratentorial region and polyhydramnios. At 28 weeks' gestation, a cesarean section was performed to avoid divisive operation during delivery. The infant died after 10 min from respiratory failure. Histological examination revealed the diagnosis of immature teratoma. Early detection of congenital intracranial tumors is crucial. The prognosis is poor with death usually occurring shortly after birth.
