Introduction: Mirror syndrome, also referred to as Ballantyne’s syndrome, is normally defined as the development of maternal edema in association with fetal hydrops. The incidence of mirror syndrome is low and few cases have been published. We describe a case report in association with fetal Ebstein anomaly and provide a systematic review on the fetal associated conditions, maternal presentatio...
INTRODUCTION International guidelines suggest that non-urgent planned deliveries be scheduled at or after 39 weeks. Despite this recommendation elective cesarean often occurs before 39 weeks. Some research has demonstrated that elective cesarean before 39 weeks poses a greater risk to the infants than at or after 39 weeks. OBJECTIVE To evaluate neonatal morbidity in term newborns born by elec...
A 32 year old Indian female was referred to our hospital at 32 weeks of gestation because of difficulty in blood group determination and further antenatal care. The results of cell and serum grouping of her blood sample were suggestive of Bombay (O(h)) Rh (D) negative phenotype. An indirect antiglobulin test (IAT) using a pool of red cells from two Bombay Rh (D) positive blood donors gave negat...
Dexamethasone or prednisolone, added in vitro to bilirubin-containing amniotic fluid, produces a time-dependent decrease in the 450-nm absorbance of the pigment. Neither the chemical determination of bilirubin in amniotic fluid nor the lecithin/sphingomyelin ratio as determined by thin-layer chromatography is affected by these glucocorticoids. The effect probably is not a result of displacement...
The objective was to determine frequency of sensorineural hearing loss (SNHL), identified by abnormal threshold in evoked potentials, absence of otoacoustic emissions and behavioral responses, auditory neuropathy (AN) (absence of evoked potentials, with preservation of otoacoustic emissions), and neurological comorbidity in infants with hyperbilirubinemia (HB) treated with exchange-transfusion ...
OBJECTIVE To report on an infrequent association of pathologies causing considerable increase in bilirubin production and a significant decrease in its excretion. DESCRIPTION The third pregnancy of an RhD negative woman. Her first child was normal and delivered to term and did not receive Rhogam. The second pregnancy was problematic due to Rh isoimmunization. She delivered a child to term, wh...
The first article of this series dealt with errors in neonatology, which occurred during the ‘‘Hands-Off’’ years, 1920 to 1970. In this period, premature infants were protected by the nurses who provided food, warmth, and isolation. The only routine treatments were silver nitrate eye drops to prevent ophthalmia neonatorum, oxygen for apnea and cyanosis, and vitamin K to prevent hemorrhagic dise...
Alloimmunization to granulocyte-specific antigens can occur during pregnancy. Maternal antibodies of IgG class can cross the placenta to result in alloimmune neonatal neutropenia. Antibodies to human neutrophil antigens anti-HNA-1a, HNA-1b, and HNA-2a have been most commonly reported to cause alloimmune neonatal neutropenia. Isoantibodies to Fc gamma RIIIb (CD16) if mother is a HNA-null phenoty...
Twenty-four out of 81 fetuses affected by anti-D isoimmunization underwent ultrasonic guided intrauterine transfusions (2.8 I. U. T.s per fetus). The absolute value and trend of delta OD 450 micron value was correlated with the severity of fetal condition as evaluated by ultrasonography following simple semiquantitative grading of ascites (mild, moderate, severe) and diagnosis of hydrops. The e...
Investigators have been studying the mechanical phenomena associated with impact to the head for many years. Several theories on the behavior of the brain during head impact have come from these studies but there has been a notable lack of information on the bulk mechanical properties of the brain which are necessary for the evaluation of these theories. This paper represents an initial attempt...
