RESUMO
OBJECTIVE: Afamin is a protein that increases in gestational diabetes but its concentration in neonates hasn't been investigated. Our objective is to compare cord blood afamin levels in neonates born to mothers with and without diabetes, and to explore its relationship with maternal and neonatal variables. METHODS: In this case control study, umbilical cord blood was collected for afamin measurement in pregestational/gestational diabetic pregnancies (n = 40) and healthy pregnancies (n = 45) after delivery. Correlation analysis was conducted to examine the relationship between afamin levels and maternal BMI, age, HbA1c, fasting and postprandial blood glucose, gestational age, birth weight. RESULTS: The diabetic group had a higher median afamin level (p < 0.001). Afamin concentrations did not differ significantly between diabetic subgroups. The concentration of afamin in cord blood was independent of maternal BMI, age, HbA1c, blood glucose, gestational age, birth weight. CONCLUSION: The concentration of afamin in cord blood of diabetic pregnancies is significantly higher, irrespective of other clinical factors.

Uterine wall perforation which is commonly seen through the posterior wall of the uterus is the most serious complication of an intrauterine device (IUD). We present a case of laparoscopic removal of an IUD from the sigmoid colon in a 31-years-old female who was admitted to hospital with a history of pelvic pain and abnormal vaginal bleeding for one month. The dislocated IUD was removed from the sigmoid colon of laparoscopic intervention without any complications. In conclusion, the treatment modality for the removal of a dislocated IUD is possible by laparoscopic surgery in selected patients where the dislocated IUD is accessible.
RESUMO
Objective: In this study, maternal and neonatal outcomes of pregnant women with positive severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) RNA tests were evaluated according to their symptomatic status. The clinical progression of SARS-CoV-2-positive pregnant women and the effect of coronavirus disease-2019 (COVID-19) on newborns was investigated. Material and Methods: This retrospective cohort study was conducted at a tertiary pandemic hospital specializing in caring for pregnant women infected with SARS-CoV-2. We included patients with a positive SARS-CoV-2 polymerase chain reaction test at delivery, subdividing them into symptomatic and asymptomatic groups. Results: Two hundred and forty-nine patients were included in the study. The mean age of the pregnant women in the symptomatic group was higher than those in the asymptomatic group (p=0.001). The iatrogenic preterm birth rates in the symptomatic and asymptomatic groups were 43.37% and 8.43%, respectively (p<0.001). Cesarean section rate was higher in symptomatic group (p=0.01). Maternal death was significantly higher in symptomatic pregnant women (p<0.001). The neonatal intensive care unit admission rate was higher in symptomatic pregnant women (p<0.001). Conclusion: The maternal and fetal outcomes for mothers with symptomatic infections tend to be worse, highlighting the importance of careful management, good follow-up and the advisability of closer monitoring.
RESUMO
BACKGROUND: Adolescent pregnant women have significant risk factors in terms of preterm birth, low birth weight, gestational and neonatal complications, and neonatal and infant deaths. In many countries, living as a refugee differs from living as a local citizen regarding education level, access to health services, and lifestyle. We aimed to compare the obstetric, perinatal, and neonatal outcomes of Turkish and refugee adolescent pregnant women admitted to a tertiary maternity center. METHODS: The study was planned as a retrospective cross-sectional. We included adolescent pregnant women who delivered between February 2018 and August 2023. Adolescent pregnant women were divided into two groups, the Turkish group and the Syrian refugee group, and compared with each other. RESULTS: One thousand and fifty-one Turkish and 742 refugee adolescent pregnant women were included in the study. Adolescent pregnancy rates are higher in refugees than in the Turkish group (p < 0.001). We found that maternal age (p < 0.001), preeclampsia rates (p=0.029), gestational age at delivery (p < 0.001), and cesarean delivery rates (p=0.02) were lower in refugee adolescent pregnant women. Furthermore, we found that the anemia rates (p < 0.001) and low birth weight newborn rates (p = 0.011) were higher in refugee adolescent pregnant women. CONCLUSIONS: Enhancing the outcomes of adolescent pregnancies among refugees necessitates a heightened focus on education regarding sexual reproduction, increased prenatal follow-ups, and enhanced training in family planning.

OBJECTIVE: The objective of this study was to learn more about the prevalence and pathophysiology of depression and anxiety that may be caused by polycystic ovary syndrome and to make plans for taking necessary precautions for this vulnerable group. METHODS: This case-control study was conducted between January 2022 and October 2022. A total of 120 women with polycystic ovary syndrome and 143 controls were included in the study. All healthy volunteers and women with polycystic ovary syndrome were evaluated using self-administered questionnaires and physical examination. Anthropometric data such as weight and height and laboratory value were documented. RESULTS: There was no significant difference between the groups in terms of demographic characteristics. When the Hospital Anxiety and Depression Scale scores of both groups were compared, both depression and anxiety scores were found to be significantly higher in women with polycystic ovary syndrome compared with the control group (OR: 3.319, 95%CI, 1.563-7.047, p<0.001 and OR: 3.238, 95%CI, 1.659-6.315, p<0.001). In the Hospital Anxiety and Depression Scale questionnaire, the rate of irregular menstruation and Ferriman-Gallwey score were statistically significant in women with polycystic ovary syndrome with high depression and anxiety scores. While serum LH levels and LH/FSH ratios were significantly different in women with polycystic ovary syndrome with high depression scores, serum LH, LH:FSH ratios, and serum total testosterone levels were found significant in women with polycystic ovary syndrome with high anxiety scores. CONCLUSION: It is clear that depression and anxiety are more common in patients with polycystic ovary syndrome than in healthy women. Our findings support previous recommendations regarding routine screening for depression and anxiety in this population.

BACKGROUND: Adolescent pregnancies are more likely to be complicated with adverse perinatal outcomes. OBJECTIVE: Assess the sociodemographic and clinical characteristics of adolescents who have delivered singleton newborns. DESIGN: Retrospective cohort. SETTINGS: A tertiary training and research hospital in Turkey. PATIENTS AND METHODS: This was a review of adolescents and adults who delivered singleton newborns at a tertiary health center between January 2018 and June 2022. Pregnant adolescents were aged <20 years. MAIN OUTCOME MEASURES: Adverse maternal and perinatal outcomes. SAMPLE SIZE: 2233 pregnant women (754 adolescents and 1479 adults). RESULTS: Turkish nationality was significantly less prevalent in pregnant adolescents than pregnant adults (P=.001). Oligohydramnios, fetal growth restriction, perineal injury and postpartum intravenous iron treatment were significantly more prevalent in pregnant adolescents than pregnant adults (P<.05 for all). The neonates born to adolescent mothers had significantly lower birth weight and first minute Apgar score than the neonates born to adult mothers (P=.001 for both). Small for gestational age, need for intensive care and death were significantly more prevalent in neonates born to adolescent mothers than those born to adult mothers (P=.001 for all). Compared with pregnant adults, pregnant adolescents had a significantly higher risk of oligohydramnios (P=.001), preterm delivery (P=.024), intravenous iron treatment (P=.001), and small for gestational age (P=.001). CONCLUSION: Due to the refugee population received by Turkey, it would be prudent to expect more frequent adolescent pregnancies. Adolescent pregnancies are more likely to be complicated with low birth weight, oligohydramnios, preterm delivery, postpartum iron treatment, lower Apgar scores, need for neonatal intensive care and neonatal death. LIMITATION: Retrospective.

Purpose: The aim of this study was to determine the scope of knowledge, attitudes, and behaviors of pregnant women about the coronavirus disease 2019 (COVID-19) vaccine. Materials and Methods: A total of 886 pregnant women were recruited for the study. A cross-sectional questionnaire was conducted on these selected participants. Data about past infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), SARS-CoV-2 infection of closely related people, and deaths due to COVID-19 among their relatives were questioned. Results: The rate of vaccination was higher (64.1%) in pregnant women with higher education levels. Informing about the vaccine, especially by health professionals, showed that the rates of vaccination (25%) increased (p<0.001). In addition, a significant increase was observed in vaccination rates with increasing age and financial income (p<0.001). Conclusion: The main limitation of our study is that the vaccine, which was approved for "emergency use", was just started to be administered to pregnant women during the study. Our findings show that our target audience, low-income, low-education, younger pregnant women should be given more attention than those who apply to the doctor for routine follow-up.
RESUMO
AIM: To compare the effectiveness of the Pfannenstiel-Kerr method (PKM) or modified Misgav-Ladach method (MMLM) in previous cesarean sections (C/Ss). METHODS: Hundred and fifteen gravidas were included with previous one C/S, using either a PKM or MMLM. Demographic characteristics, operative outcomes, surgical complications, and neonatal outcomes were compared in two groups. RESULTS: The mean operative time (18.0 ± 3.5 vs. 23.5 ± 5.7 min; p < 0.0001) and mean extraction time (90.1 ± 41.2 vs. 208.1 ± 79.1 s; p < 0.0001) were significantly shorter in the MMLM group than the PKM group. Postoperative recovery (mobilization, normalization of bowel function, need for analgesics, time to oral feeding, and intra-operative blood loss) was similar between the MMLM and PKM groups. CONCLUSION: The MMLM appears to be a faster alternative to PKM for previous C/Ss, with similar results as in previous studies with primary CSs.

Turner syndrome is associated with a higher frequency of heart defects detected prenatally when compared to postnatal reports. The most common heart defects detected prenatally are hypoplastic left heart syndrome and coarctation of the aorta. We report a case involving a fetus at 16 gestational weeks with a septated cystic hygroma located on the neck and head, an interventricular septal mass, a hypoplastic left ventricle due to aortic stenosis, mitral stenosis, and a hypoplastic aortic arch with a karyotype of mos 45, X, [47 cells]/47, XXX [3 cells]. The autopsy findings confirmed our prenatal diagnosis with a final diagnosis of Turner syndrome and congenital cardiac vascular malformation.

RESUMO
OBJECTIVE: To determine the changes in cervical collagen during the first trimester of pregnancy and to evaluate the collagen deficit in cases with a previous diagnosis of cervical insufficiency (CI). MATERIALS AND METHODS: Cervical punch biopsies were obtained from 66 patients divided into three groups: patients with recurrent abortions due to CI (CI group; n = 8); first-trimester abortion group (study group; n = 37), subdivided into three groups according their gestational week (<7, 7-9 and 9-12 weeks), and patients with cervical biopsy due to gynecologic reasons (control group; n = 12). Collagen quantity was determined by a biochemical method that measured the levels of hydroxyproline (HOP) in dry cervix tissue. RESULTS: The HOP concentrations were significantly higher at lower gestational ages (p = 0.001). Collagen quantity was lowest in the CI group compared with other groups (p < 0.001). CONCLUSION: This study shows collagen component of cervix decreases as pregnancy advances through the first trimester. Cervical collagen concentration is lower in women with a history of CI compared to controls who has not a history of CI.

Introduction. Although the incidence of pregnancy-associated sacroiliitis is low, it is associated with significant morbidity and mortality. Timely diagnosis of the disease is confusing due to its nonspecific clinical features. Case. A 28-year-old woman at 34 weeks of gestation with severe pain in her right buttock radiating down the backside of the right thigh was admitted to our hospital. White blood cell (WBC) count and C-reactive protein (CRP) were elevated. The pelvic magnetic resonance imaging (MRI) scan revealed right sacroiliitis. Conclusion. Infectious sacroiliitis should be considered as a differential diagnosis even in low-risk women who present with debilitating pelvic pain in pregnancy and medical treatment should not be delayed.
RESUMO
Primary torsion of the omentum majus is a rare cause of acute abdomen and it commonly mimics acute appendicitis. An eight year old boy was admitted to our clinic with symptoms and clinical findings of perforated appendicitis. The patient underwent emergency laparotomy at which a normal appendix and serosanguinous fluid in the peritoneal cavity were observed. The operative diagnosis was primary torsioned omentum. In the present study, preoperative and operative findings of primary omental torsion that differentiated it from acute appendicitis are discussed in the light of the literature.
RESUMO
OBJECTIVE: Mirror syndrome (Ballantyne's syndrome) refers to the association of fetal hydrops and maternal preeclampsia. The aim of this study was to determine the relation and incidence between fetal hydrops and preeclampsia in our clinic. METHODS: A retrospective review of patients associated with fetal hydrops and findings with preeclampsia was used. Seventy-five cases with single pregnancy and diagnoses with nonimmune hydrops fetalis were found. According to the data 4 cases were found related with preeclampsia. RESULTS: Mirror syndrome is rarely encountered and underdiagnosed. We found a frequency of 5.3% (4 cases in 75 affected pregnancies) for single non-immune hydrops cases in which maternal hypertension occurred. Fetal outcome is depending on etiology and prognosis is mainly very low. Maternal symptoms and laboratory findings are resolving after intrauterine fetal death or delivery. CONCLUSION: Hydrops fetalis must be considered as a potential risk factor for preeclampsia. It is important that this clinical condition has a potential of about 5% for proceeding preeclampsia.

The aim of this study was to determine the distribution of cases associated with congenital abnormalities during the following three periods: pregnancy, birth, and the neonatal period. This was a retrospective study of cases between 2002 and 2006. All abnormal pregnancies, elective terminations of pregnancies, stillbirths, and births with congenital abnormalities managed in the Neonatology Unit were classified based on the above distribution scheme. During the 5-year study period, 1906 cases with congenital abnormalities were recruited, as follows: 640 prenatally detected and terminated cases, with most abnormalities related to the central nervous system, chromosomes, and urogenital system (56.7%, 12.7%, and 8.9%, respectively); 712 neonates with congenital abnormalities (congenital heart disease [49.2%], central nervous system abnormalities [14.7%], and urogenital system abnormalities [12.9%]); and hospital stillbirths, of which 34.2% had malformations (220 prenatal cases [34.4%] had multiple abnormalities, whereas 188 liveborn cases [26.4%] had multiple abnormalities). The congenital abnormalities rate between 2002 and 2006 was 2.07%. Systematic screening for fetal anomalies is the primary means for identification of affected pregnancies.

BACKGROUND/PURPOSE: Intestinal damage in patients with gastroschisis is characterized by bowel wall thickening, intestinal dilatation, mesenteric shortening, and a fibrous peel. The prevention of intestinal damage in gastroschisis by amnio-allantoic fluid (AAF) exchange has been reported using histologic and macroscopic evaluation of intestines, but the effects of this treatment on bowel contractility have not been investigated. The current study was performed to determine the effect of AAF exchange on the intestinal contractility in chick embryos with gastroschisis. METHODS: Thirteen-day-old fertilized chick eggs were used. Gastroschisis was created through amnio-allantoic cavity. There were 3 study groups: control group, gastroschisis-only group, and gastroschisis-plus-exchange group. The bowels were evaluated by an in vitro muscle strip technique, and the response was expressed as a percentage of the maximum acetylcholine evoked contraction (E(max)) in each tissue obtained. Additionally, parasympathetic ganglion cells per 10 plexus at the intestinal wall were counted. Differences between groups were analyzed by analysis of variance (ANOVA) followed by Tukey-Kramer. Probabilities of less than 5% were considered significant. RESULTS: The intestines were thickened and covered by fibrous peel in the gastroschisis-only group when compared with the control group and the gastroschisis exchange group morphologically. There was a statistically significant decrease in contractility in the gastroschisis-only group compared with the control group (P <.05). It exerted 42.03 +/- 46.73% contraction of control group's E(max). This decrease in contractility was significantly reversed in the exchange group (P <.05; E(max) value of gastroschisis plus exchange group was 71.45 +/- 23.54% of control group's E(max)). Although the number of ganglia per 10 plexus was 76.7 +/- 4.3 in the control group, it was measured 28% less in the gastroschisis-only group (P <.05). There was no significant difference between the ganglion numbers of control and exchange groups. CONCLUSIONS: Prenatal AAF exchange treatment prevents decreased bowel contractility in gastroschisis. Gastroschisis does not affect intestinal ganglia morphology, but the number of ganglion cells decreases. AAF exchange prevents these functional and morphologic adverse effects of disease. By these findings the expectancy of a better clinical result in gastroschisis with intrauterine pretreatment by amniotic fluid exchange increases.

The aim of the present study was to investigate whether high-pressure carbon dioxide insufflation facilitates mucosal dissection in the transanal endorectal pull-through (TEPT) operation performed in Hirschsprung's disease in a rabbit model. In the study, ten New Zealand rabbits were used. In six of the rabbits, CO(2) under 50 mmHg pressure was insufflated into the submucosal area through a 25-gauge scalp needle inserted 0.3 cm over the dentate line. Two of the rabbits were taken for histopathological examination. In four rabbits, the TEPT operation was performed and in another four the operation was performed without CO(2) insufflation. Histopathological examination in the CO(2)-insufflated group of rabbits showed that at transversal incisions mucosa was seen to be separated circumferentially from submucosa by high pressure CO(2) and at longitudinal incision the separation was seen to be complete along the anal canal. It was noted that mucosal dissection was rapid, non-bloody and without induced mucosal tears or perforation; however, in the non-insufflated group the operation was time-consuming, bloody and more difficult to perform and needed meticulous care. In the present study, it was seen that submucosal high pressure CO(2) insufflation in rabbits facilitates mucosal dissection in the TEPT operation and is easy to perform, time-saving and highly economical.

BACKGROUND: The primary goal of surgical therapy for short bowel syndrome is to increase intestinal absorptive capacity. Many surgical procedures have been described for this purpose. One of these is ileal reverse-segment procedure. This procedure after massive small-bowel resection is an alternative way to treat short bowel syndrome, but how it affects intestinal morphology in short bowel syndrome has not been investigated. The aim of this study is to investigate macroscopic and microscopic effects of reverse-segment procedure on the short bowel. METHODS: Twenty rats underwent resection of 80% of the small bowel. The rats were separated into two groups (n = 10). In the first group (reverse group), a reverse segment was formed by twisting a 2-cm ileal segment 180 degrees, without damaging its vascularity. In the second group (control group), a 2-cm ileal segment was resected, preserving its mesentery, and end-to-end anastomosis was performed to maintain the intestinal passage. The segment was not twisted 180 degrees. The 2-cm proximal (jejunal) and distal (ileal) segments of the resected bowel were reserved for histologic investigation. Two months later, the rats were killed and the jejunal and ileal segments were evaluated morphologically. RESULTS: In the reverse group, body weight and total intestinal length significantly increased (14% more than in the control group). The diameter of both proximal (jejunal) and distal (ileal) segments in the reverse group also increased 53.8% and 22.8%, respectively ( P < 0.05). Histologically, crypt depth and villus height of the ileal segment in the reverse group increased 15.2% and 18.2% more than in the control group ( P < 0.05). No histologic change was observed at the jejunal level except for intestinal muscle thickness. CONCLUSIONS: Ileal reverse-segment procedure in rats with short bowel syndrome 1) does not cause intestinal obstruction, 2) increases total bowel length and body weight, 3) increases the diameter of both jejunal and ileal segments, and 4) increases villus height and crypt depth only at the ileal level. For this reason, reverse-segment procedure positively affects intestinal adaptation.
