RESUMEN

Ovarian torsion is agynecologic emergency that affects females of all ages. Early diagnosis is important to preserve ovarian function. The false positive rate for sonographic diagnosis of ovarian torsion is 50%; therefore, a new real-time approach is required to improve diagnostic accuracy. We investigated diffuse reflectance spectroscopy for diagnosing ovarian torsion. Spectroscopic measurements were performed in vivo prior to, during and after detorsion. After bilateral oophorectomy, hemoxygenase and myeloperoxidase enzyme activity in ovarian tissue was evaluated and the tissues were examined for pathology. Spectroscopic data were compared to histopathological and biochemical data to assess the diagnostic value of the spectroscopic method for differentiating healthy and damaged ovarian tissue. We found a good correlation between spectroscopy and histopathology. We also found a correlation between the spectroscopic data and heme oxygenase enzyme activity. We found no correlation between the histopathological tissue damage score and myeloperoxidase enzyme activity. Diffuse reflectance spectroscopy may be of prognostic and diagnostic value for ovarian torsion in vivo.

RESUMEN

OBJECTIVES: To evaluate the effectiveness and reliability of microinsert hysteroscopic sterilization method at short- and long-term. MATERIALS AND METHODS: In the period between January 2004 and December 2005, 34 patients who submitted to the present gynecology outpatient clinic seeking for permanent contraception and accepted tubal sterilization with microinsert method were included in this prospective, interventional study. RESULTS: Bilateral microinsert placement was successful in 28 (87.5%) of 32 patients that underwent the procedure. In all of the 30 patients (100%) in whom the placement procedure was attempted, bilateral tubal occlusion was documented by hysterosalpingogram (HSG) including the two patients in whom unilateral placement was carried out. First three procedures were performed under general anesthesia. Local or general anesthesia was not administered in any other cases (97.5%). The mean visual analogue scale score for pain felt during the procedure was 3.1. The mean procedure time was 11.5 ± 4.88 (5-22) minutes, the average time from beginning the procedure to discharge of the patients was 41.7 ± 18.5 (15-94) minutes. One intrauterine pregnancy was detected in one of the patients nine months after cessation of the alternative contraceptive period. This patient was excluded from the follow-up. At short-term all patients rated their microinsert-wearing tolerance as good or excellent. At eighth year, three patients were lost to follow-up. Mean follow-up time was 83.4 ± 15.0 (36-103) months. During 2,420 woman-months of follow-up, no other pregnancies were detected. Almost all of the patients were happy with the procedure and recommended it to a friend. CONCLUSION: Essure microinsert is a safe, effective, minimally invasive sterilization method which can be performed in outpatient settings without any anesthesia requirement. It appears to be a good alternative to laparoscopic tubal sterilization. The procedure time and the time to discharge are brief. Patient tolerance during the procedure and at long-term is very good.

RESUMEN

Intrauterine growth restriction (IUGR) is one of the most common problems in obstetrics. Ischaemia-modified albumin (IMA), a product deriving from albumin as a result of the modification by oxidative free radicals in response to hypoxia, was previously used as a marker of ischaemia in acute coronary syndrome. We performed this study to determine whether umbilical venous IMA levels are associated with IUGR. A total of 40 pregnancies with IUGR were compared with 40 of normal fetal development. Blood samples were obtained from the umbilical vein after delivery. IMA levels in the IUGR group were higher than in the control group (78.74 ± 6.87 vs 74.43 ± 7.84 U/ml, respectively, p = 0.011). An elevated IMA level was associated with IUGR (OR: 1.079, 95% CI: 1.000-1.163, p = 0.049). We suggest that IMA, which was formerly proved to arise in ischaemic conditions, may also be a valuable marker in perinatal hypoxia and IUGR detection.

RESUMEN

It has been reported that, compared with simple increased nuchal translucency, fetal cases with septated cystic hygroma (CH) are more likely to face perinatal handicaps. However, pediatric outcomes and proper prenatal counseling for this anomaly have not yet been truly defined. We performed this study to determine pregnancy and pediatric outcomes of fetuses with septated CH. We searched records for cases with septated CH and collected data for structural abnormalities, karyotype analysis, and pregnancy outcomes. Fetuses born with septated CH were also evaluated for their pediatric outcomes. Sixty-nine fetuses with septated CH were enrolled in the study. Results showed that chromosomal abnormalities were present in 28 fetuses (40.6%), and the most common aneuploidy was Turner syndrome (n=14, 20.3%); 16 (23.2%) of the remaining cases, in which aneuploidy was not found, had coexistent structural malformations; 25 (36.2%) cases had normal karyotype and morphology. The total number of live births and infants with unfavorable neurologic follow-up were 13 (18.8%) and 2 (2.9%), respectively. Septated CH is associated with poor perinatal outcomes; therefore, karyotype analysis and ultrasonographic anomaly screening should be performed as initial steps, and expectant management should be offered to couples with euploid fetuses that have normal morphology.

RESUMEN

The authors describe uterus retrieval in cadavers. Uterine retrieval with its vasculature could be successfully achieved in four of the presented cases. Special attention was given to dissection of bilateral ureters and hypogastric vasculature. Uterine retrieval with its vasculature and supporting sacrouterine,vesicouterine peritoneal folds is an anatomically feasible procedure in preparation for uterus transplantation.

RESUMEN

UNLABELLED: The purpose of the study was to compare laparoscopic total radical hysterectomy with classic radical hysterectomy regarding parametrial, and vaginal resection, and lymphadenectomy. METHODS: Laparoscopic or laparotomic total radical hysterectomy with advantages and disadvantages was offered to the patients diagnosed as having operable cervical cancer between 2007 and 2010. Lymph node status, resection of the parametria and vagina, and margin positivity were recorded for both groups. Data were collected prospectively. Statistical analysis was performed with the SPSS statistical software program. RESULTS: Totally, 53 cases had classical abdominal radical hysterectomy and 35 laparoscopic radical hysterectomy, respectively. Parametrial involvement was detected in four (11.4%) cases in laparoscopic radical surgery versus nine (16.9%) in laparatomic surgery. All the cases with parametrial involvement had free surgical margins of tumor. Also there were no significant statistical differences in lymph node number and metastasis between the two groups. CONCLUSION: There is no difference in anatomical considerations between laparoscopic and laparatomic radical surgery in the surgical management of cervical cancer.

RESUMEN

OBJECTIVE: To investigate whether first trimester low PAPP-A levels are associated with adverse pregnancy outcomes. METHODS: A case control retrospective study including 663 pregnant women whose gestational age ranged between 11 and 14 weeks attending prenatal care at Akdeniz University Hospital was carried out. Chromosomal abnormalities, spontaneous abortions, and multiple pregnancies were excluded from the study. Finally 318 singleton pregnancies were included in this study. Pregnant women whose PAPP-A levels were < or =10th percentile were compared with PAPP-A levels > 10'h percentile for the frequency of pregnancy complications such as SGA, preeclampsia, preterm delivery, gestational diabetes mellitus and gestational hypertension. RESULTS: The most common complication of pregnancy was SGA (9.4%, n=30). There was no significant association between low PAPP-A levels and incidence of subsequent pregnancy outcomes. Maternal age was found to be a risk factor for gestational diabetes (p = 0.00). Small for gestational age was significantly associated with nulliparity and smoking during pregnancy (p = 0.03 and p = 0.01, respectively). CONCLUSION: First trimester of low PAPP-A level (< or = 10th percentile) was not associated with SGA, preeclampsia, preterm delivery, gestational hypertension or gestational diabetes mellitus.

RESUMEN

AIM: To determine whether preeclampsia is associated with an increase in placental apoptosis and altered expression of mediators of apoptosis such as Fas, Fas ligand, caspase-3, p53, Bcl-2 and Bax. METHODS: Placental samples obtained from 20 women with preeclampsia and 14 normal women were analyzed using the Klenow, Frag-EL DNA fragmentation detection kit for apoptosis. Expression of Fas, Fas ligand, caspase-3, p53 Bcl-2, and Bax was assessed using immunohistochemistry. RESULTS: The median percentage of apoptotic nuclei in trophoblasts was significantly higher for the preeclampsia group than for the controls (6.9 vs 0.25; p =.001). Fas ligand expression was significantly higher in the decidua among the subjects with preeclampsia compared with controls (1.2 vs 0; p = .023). Otherwise no difference was observed in the expression of Bax , Bcl-2, p53, caspase-3, and Fas between groups. CONCLUSION: Increased apoptosis in preeclampsia may not be associated with significant alterations in Fas, Fas ligand, caspase-3, p53, Bcl-2 and Bax expression.
