RESUMO
BACKGROUND: Intestinal disorders are common in very low-birthweight infants. The purpose of this study was to evaluate the impact of prophylactic oral Gastrografin® (diatrizoate acid) on meconium-related ileus (MRI) in extremely preterm infants. METHODS: This was a retrospective case-control study of infants born extremely preterm at <28 weeks of gestation and treated with diatrizoate acid (prophylactic group) or not (control group) in the periods 2007-2014 and 2000-2009, respectively. In the 2007-2014 period, 120 infants received prophylactic diatrizoate acid solution. From the 165 infants in the control group, we selected 120 infants matched for gestational age. Cases of death before 72 h of life or congenital abnormalities were excluded. Intestinal disorders, time until full enteral feeding, duration of hospital stay, mortality rate, and neurodevelopmental outcome were compared. RESULTS: MRI occurred in six infants in the control group and in none of the infants in the prophylactic group (P = 0.039). Median time until full enteral feeding was 25 versus 22 days (P < 0.01), hospital stay was 142 versus 126 days (P < 0.01), and mortality rate for infants aged 24-27 weeks was 8.2% versus 0% (P = 0.021), respectively. CONCLUSIONS: Prophylactic oral diatrizoate acid reduced MRI in extremely preterm infants without side-effects and decreased the mortality rate of infants born at 24-27 weeks, and is thus beneficial in extremely preterm infants.

Here we report a case of fetal left ventricular non-compaction cardiomyopathy with ascites and cardiac dysfunction at a gestational age of 34+5 weeks. Laboratory tests did not reveal any sign of viral infection in utero. A female neonate weighing 2436 g was delivered by emergency cesarean section due to non-reassuring fetal status. Postnatal echocardiography confirmed left ventricular non-compaction cardiomyopathy with severe cardiac failure. Although she was treated effectively during the acute period by continuous flow peritoneal dialysis, surgical ligation of a patent ductus arteriosus, and inhaled nitric oxide, she died on day 41 of life. Symptoms of severe cardiac dysfunction appeared antenatally in this patient and the outcome was poor.

Objective. The improvement of the accuracy of fetal heart rate (FHR) pattern interpretation to improve perinatal outcomes remains an elusive challenge. We examined the impact of an FHR centralization system on the incidence of neonatal acidemia and cesarean births. Methods. We performed a regional, population-based, before-and-after study of 9,139 deliveries over a 3-year period. The chi-squared test was used for the statistical analysis. Results. The before-and-after study showed no difference in the rates of acidemia, cesarean births, or perinatal death in the whole population. A subgroup analysis using the 4 hospitals in which an FHR centralization system was continuously connected (compliant group) and 3 hospitals in which the FHR centralization system was connected on demand (noncompliant group) showed that the incidence acidemia was significantly decreased (from 0.47% to 0.11%) without a corresponding increase in the cesarean birth rate due to nonreassuring FHR patterns in the compliant group. Although there was no difference in the incidence of nonreassuring FHR patterns in the noncompliant group, the total cesarean birth rate was significantly higher than that in the compliant group. Conclusion. The continuous FHR centralization system, in which specialists help to interpret results and decide clinical actions, was beneficial in reducing the incidence of neonatal acidemia (pH < 7.1) without increasing the cesarean birth rate due to nonreassuring FHR patterns.

OBJECTIVE: We conducted the study to see the incidence of thyroid dysfunction in women with obstetrical high-risk factors. METHODS: We retrospectively reviewed medical charts of high-risk pregnant women who had examination for thyroid function during pregnancy. Women were divided according to clinical presentation, symptoms of thyroid disease and those with a personal history of thyroid disease (thyroid disease, n = 32), intrauterine growth restriction (IUGR, n = 115), diabetes mellitus (diabetes, n = 115), hypertension (n = 63), intrauterine fetal death (IUFD, n = 52), and placental abruption (abruption, n = 15). The incidence of thyroid dysfunctions including hyperthyroidism or hypothyroidism was compared. RESULTS: The overall prevalence of thyroid dysfunction was 24.7%. The incidence of thyroid dysfunction in each group was as follows: 31% in thyroid disease, 25% in IUGR, 30% in diabetes, 27% in hypertension, 12% in IUFD, and 7% in abruption. Except IUFD, the incidence was not statistically significant from the group of thyroid disease (thyroid disease versus IUFD, P = 0.03 by χ (2) test). Thyroid disease represented for only 10% of all thyroid dysfunctions. CONCLUSION: Testing of women with a personal history or current symptoms of thyroid disease during pregnancy may be insufficient to detect women with thyroid dysfunction, who will become at high-risk pregnancy.

AIM: The aim of this study was to determine the correlation between non-reassuring fetal heart rate (NRFHR) patterns and poor neonatal outcome in placental abruption. MATERIAL AND METHODS: A retrospective study was performed involving 83 placental abruptions with a live fetus at one tertiary and one secondary hospital in Miyazaki prefecture, Japan. We examined the correlation among NRFHR, umbilical arterial blood gas status, and neonatal poor outcomes, including neonatal death (ND) and cerebral palsy (CP). RESULTS: A total of 83 cases were divided into bradycardia (n=27), recurrent late deceleration (rLD, n=29), severe variable deceleration or prolonged deceleration (sVD/PD, n=8), and other cases (n=19). In the bradycardia group, the incidence of low umbilical artery (UA) pH (<7.0) was 59% and the average UA pH was 6.96±0.22. Among these cases, 10 showed severe bradycardia (less than 80 b.p.m.) and an average UA pH of 6.85±0.24, and four cases resulted in poor outcome (three CP and one ND). In the rLD group, the incidence of low UA pH (<7.0) was 7% and the average UA pH was 7.24±0.12. In this group, a 40-week-old fetus with umbilical phlebitis had a lower UA pH (6.92) and developed CP. In the sVD/PD group, there were no cases of a low UA pH (<7.0) and the average UA pH was 7.30±0.04. In this group, a 31-week-old boy with a UA pH of 7.36 developed CP (PVL). The remaining 19 cases had no CP. CONCLUSION: Poor neonatal outcome of placental abruption is closely related to NRFHR, especially the degree of bradycardia. In the rLD and sVD/PD groups, risk factors, such as prematurity and fetal inflammation, co-existed.

A case of umbilical cord hemangioma with a large cystic mass, diagnosed by ultrasound at 18 weeks of gestation, is reported. A normal female infant was born at 39 weeks of gestation. The umbilical cord was 32 cm long with a cystic mass (10 × 10 × 8 cm). Histopathologic examination of the umbilical cord revealed a hemangioma with myxomatous degeneration, presenting as a large cyst with thinning of the umbilical venous wall. A total of 33 umbilical cord hemangioma cases have been reported in detail, and only seven cases had a pseudocystic degeneration. The associated pathologic findings of umbilical cord hemangioma are reviewed.

BACKGROUND: Due to circulatory instability, premature infants require volume loads, catecholamines and steroid supplementation to improve mortality and neurodevelopmental outcome. However, a complete quantitative analysis concerning the relationship between supplementation and gestational age, especially in infants born at 22 to 24 weeks of gestation, is lacking. AIM: To investigate whether less mature infants need higher doses of catecholamine, volume loads and steroid, and whether those who require higher doses have poorer outcome. STUDY DESIGN: A retrospective, observational study was performed at a tertiary center in a university setting. Among the consecutive 221 premature infants born at 22 to 28 weeks of gestation, we selected 108 infants who had no apparent pathological conditions other than prematurity. Catecholamines, volume loads and steroid, given to attain sufficient blood pressure and urinary output, were quantitatively analyzed during the first 24 hours. OUTCOME MEASURES: Quantity of catecholamines, volume expanders and steroid supplementation as a function of gestational age and childhood outcome at 2 years. RESULTS: Catecholamines and volume loads were increased in a step-wise manner with decreasing gestational age. Intact survival rate was significantly lower in infants born before 25 weeks of gestation compared with the more mature infants. Among infants born at 22 to 24 weeks' gestation, catecholamine and volume load increased significantly in poor outcome infants compared with good outcome infants. CONCLUSIONS: From a developmental viewpoint, progressively larger doses of catecholamine, volume expanders and corticosteroid are required to stabilize circulatory adaptation to neonatal life in infants between 22 to 28 weeks of gestation.

A solid well-circumscribed ovarian tumor in a 63-year-old Japanese woman is reported. Histologically, the tumor consisted predominantly of a hemangiomatous component with a small cyst lined by a respiratory ciliated epithelium. The remaining ovarian stroma showed a marked proliferation of luteinized cells that were strongly positive for inhibin immunohistochemically. Neither dermoid nor other teratomatous components were found, even in the serial sections of the tumor. To date, vascular tumors of the ovary are uncommon and some cases of ovarian hemangioma have been reported. However, their origin, whether a monodermal teratoma or a true neoplasm arising in the ovarian stroma, has not yet been elucidated. When a hemangiomatous proliferation is found in an ovarian tumor, a thorough microscopic search for teratomatous components is necessary before diagnosing the tumor as a pure hemangioma.
