1/215. Unusual site for oesophageal perforation in an extremely low birth weight infant.A male infant born at 26 weeks gestation became unwell at 10 days of age with blood-stained pharyngeal aspirates. The chest radiograph revealed a feeding tube in the right pleural cavity, indicating a perforation of the thoracic oesophagus. The infant had had a chest drain inserted on the right side on two previous occasions. These had been allowed to remain across the mediastinum at the site of the subsequent perforation. The infant was successfully managed conservatively with no long-term sequelae The unusual site of the perforation led us to conclude that pressure necrosis from the drains was a contributing factor in the aetiology. CONCLUSION: Oesophageal perforations in the neonate, in contrast to the adult, can be managed conservatively.- - - - - - - - - - ranking = 1keywords = gestation (Clic here for more details about this article) |
2/215. cytomegalovirus associated neonatal pneumonia and Wilson-Mikity syndrome: a causal relationship?lung injury caused by intrauterine inflammation has recently been strongly implicated in the pathogenesis of Wilson-Mikity syndrome (WMS). This article supports this theory by suggesting a causative role of intrauterine cytomegalovirus (CMV) infection for the development of WMS. A male premature infant, born at 33 weeks of gestational age, developed chronic lung disease compatible with WMS and diagnostic evaluation was positive for CMV infection. High-resolution computed tomography scan and lung histology revealed typical features of WMS in association with signs of interstitial pneumonia. CMV was found in urine, breastmilk, bronchoalveolar lavage material and lung tissue from open lung biopsy. Follow-up after treatment with ganciclovir and steroids showed resolving lung disease at the age of 6, 10 and 16 months, with lung function signs of mild obstruction. Assuming that a chance coexistence of cytomegalovirus pneumonia and Wilson-Mikity syndrome is rather unlikely, it is possible that intrauterine cytomegalovirus infection caused a pattern of lung injury consistent with Wilson-Mikity syndrome. Further cases of Wilson-Mikity syndrome should be investigated as to a possible role of congenital infection.- - - - - - - - - - ranking = 1keywords = gestation (Clic here for more details about this article) |
3/215. brain dysgenesis in Cornelia de lange syndrome.The neuropathological findings in a neonatal case of Cornelia de lange syndrome (CDLS) were described. Two different types of lesions were revealed in the affected brain. The first type was classified as perinatal hypoxic-ischemic brain damage, associated with cyanotic congenital heart anomalies: subarachnoideal, intraventricular, and parenchymal hemorrhage, and multiple necrosis in the cerebral white matter, basal ganglia, internal capsule, thalamus, mammillary bodies and dentate nucleus. This type may be non-specific and common in premature babies dying soon after birth. On the other hand, the second type was classified as congenital dysgenesis of the brain: microbrachycephaly, immature or simple convolution pattern of the cerebral gyri, thickened leptomeninges, persistent subpial granule cells, hypoplasia of the anterior thalamic nuclei, neurohypophysis, lateral geniculate body, cerebral peduncle, ventral pons and cerebellar internal granular layer, and heterotopic cell nests in the cerebellar white matter. This type may indicate that the maturation of the brain can be disturbed in the fetal period, particularly in the mid-gestational period. In conclusion, pathognomonic or specific changes of CDLS might be absent in the brain. However, congenital dysgenesis of the brain, especially that found in the diencephalon and the cortico-ponto-cerebellar system, may constitute morphologic evidence explaining the severe growth retardation and neurological abnormalities in CDLS.- - - - - - - - - - ranking = 1keywords = gestation (Clic here for more details about this article) |
4/215. chorioamnionitis with intact membranes caused by capnocytophaga sputigena.We report a case of chorioamnionitis with intact membranes caused by capnocytophaga sputigena. The pregnant woman was hospitalised in preterm labor without fever, neither tenderness, just regular contractions. In spite of the tocolitic treatment the patient gave birth to a girl at 29 weeks' gestation, weighing 1220 g and transferred to intensive care. The newborn had clinical and biological signs of infections and was initially treated by ampicillin, cephalosporin and metronidazol. capnocytophaga sputigena was found on membranes, cord, amniotic fluid and placenta. It was also identified in maternal endocervix culture. Histologic findings showed a focal chorioamnionitis. This was the fourteenth reported case of infection due to capnocytophaga species occurring in pregnancy. All the cases are reviewed.- - - - - - - - - - ranking = 1.0439697707571keywords = gestation, pregnancy (Clic here for more details about this article) |
5/215. Scar formation after skin injury to the human foetus in utero or the premature neonate.A macroscopically visible scar was present at birth in three infants with a history of injury during amniocentesis at 16-20 weeks' gestation. In several neonates born between 21 and 31 weeks' gestation, chemical injury to the skin caused by extravasation of calcium gluconate healed by formation of a large scar. In the infant born at 21 weeks, biopsy of the injured area showed infiltration by large numbers of neutrophils and macrophages. It appears that a very immature neonate can mount a prominent inflammatory reaction and that both a midtrimester foetus and a very immature neonate heal injuries to the skin by scar formation and not by scarless healing.- - - - - - - - - - ranking = 2keywords = gestation (Clic here for more details about this article) |
6/215. Extensor tendon lacerations in a preterm neonate.A fetus of 30-weeks' gestation sustained 2 extensor tendon lacerations as an intraoperative complication of an emergency cesarean section. This report describes treatment of the tendon lacerations in the preterm neonate using 2 different repair techniques which both yielded an excellent clinical outcome.- - - - - - - - - - ranking = 1keywords = gestation (Clic here for more details about this article) |
7/215. pituitary gland gumma in congenital syphilis after failed maternal treatment: a case report.A preterm, very low birth weight infant was born to a mother with early latent syphilis who was treated 10 days and 3 days before delivery with 2.4 mU of benzathine penicillin. The infant had clinical, laboratory, and radiographic abnormalities consistent with congenital syphilis, ie, a Venereal disease research Laboratory test titer that was fourfold greater than was the maternal titer, hepatosplenomegaly, abnormal liver function tests, pneumonitis, osteochondritis of the long bones, and cerebrospinal fluid (CSF) examination showing a reactive Venereal disease research Laboratory test, pleocytosis, and elevated protein content. The infant died on the third day of life, and an autopsy revealed an evolving gumma of the anterior pituitary. immunoglobulin m immunoblotting of serum and CSF was positive, and polymerase chain reaction detected treponema pallidum dna in endotracheal aspirate and CSF. This case highlights the pathologic abnormalities observed in congenital syphilis and focuses on the rare finding of an evolving anterior pituitary gumma. Furthermore, it documents the failure of maternal syphilis treatment during the last 4 weeks of pregnancy to cure fetal infection and supports the recommendation that all infants born to mothers with syphilis treated during the last 4 weeks of pregnancy should receive penicillin therapy.- - - - - - - - - - ranking = 0.087939541514247keywords = pregnancy (Clic here for more details about this article) |
8/215. Multiple atresias in a low-birth-weight twin.This report describes a case of 16 small bowel atresias in a twin who was born at 31 weeks' gestation, weighing 1,690 g. All atresias and intestinal segments of 5 cm or less in length were resected, resulting in nine primary anastomoses, preserving 75% (107 cm) of his initial small bowel length. The baby went home on full oral feedings after 10 weeks. Multiple anastomoses in the low-birth-weight neonate can be tolerated with the functional benefit of maximal bowel length. The time taken to tolerate feedings appears to be independent of the number of anastomoses. Vascular anastomoses associated with monochorionic twinning may place both fetuses at risk of intestinal atresia in the event of an ischemic insult, either concurrently or with the demise of one affecting the other. Prenatal ultrasound scan appears to be useful for monitoring the evolution of intestinal atresia. However, the risks of extreme prematurity preclude the delivery of the affected baby at the time of initial diagnosis, and as yet it is unknown whether early delivery will alter the number, type, or prognosis of multiple atresias.- - - - - - - - - - ranking = 1keywords = gestation (Clic here for more details about this article) |
9/215. Case of the month: January 1999--fetus with echogenic mass in third ventricle.A 29-week gestational age newborn male infant was found to have an echogenic mass in the 3rd ventricle by prenatal ultrasound 2 weeks prior to delivery. At delivery he was poorly responsive and had hydrocephalus and ascites. A CT scan after birth showed cerebral infarction, amorphous tissue in the left hemisphere and numerous calcifications. Despite supportive treatment he died 4 days after birth. Postmortem examination of the brain revealed marked distortion of the architecture and a supratentorial undifferentiated neoplasm consistent with a PNET. The tumor showed extensive areas of hemorrhage and necrosis and involvement of lateral and third ventricles, brain parenchyma, and meninges.- - - - - - - - - - ranking = 1keywords = gestation (Clic here for more details about this article) |
10/215. Primary aldosteronism caused by aldosterone-producing adenoma in pregnancy--complicated by EPH gestosis.pregnancy in conjunction with primary aldosteronism is an unusual occurrence. We report a 28-year-old woman who presented with mild hypertension and hypokalemia as manifestations of primary aldosteronism caused by an aldosterone-producing adenoma in the left adrenal gland during pregnancy. Although the diagnosis was straightforward, the patient refused to undergo the proposed operation during the second trimester of her pregnancy. She was not admitted to hospital until she developed EPH gestosis in the 27th week of gestation, which had an unfavourable outcome for the infant who died nine days after delivery. The patient underwent a laparoscopic adrenalectomy which resulted in normalization of blood pressure and blood potassium levels. In cases of aldosterone-producing adenoma, surgery in the second trimester is the most appropriate option to avoid a poor obstetric outcome.- - - - - - - - - - ranking = 1.2638186245427keywords = gestation, pregnancy (Clic here for more details about this article) |
