A study of 866 vaginal swabs from non-pregnant women showed that 167 (19.3%) contained Group B beta-haemolytic streptococci, with a predominance of Types 3 (31.4%) and Ib (25.2%). The incidence of severe neonatal infections due to Group B streptococci during a 3 1/2 year period at The Prince of Wales Hospital was examined, and a study was made of the distribution of serotypes and associated clinical features (including prematurity and abnormal deliveries) in 16 neonates with septicaemia and/or meningitis admitted to the Royal Alexandra Hospital for Children, and the Paediatric Department of The Prince of Wales Hospital. From this study it was concluded that prophylactic antibiotic therapy should be administered to neonates with evidence of Group B streptococcal colonization of the throat, umbilicus, or gut, when there is also evidence of prematurity, prolonged interval between membrane rupture and delivery, or other associated obstetric complications.

There has been a gradual accumulation of reported Campylobacter fetus human infections since the first description in 1947. The taxonomy of these fastidious and morphologically confusing organisms has been recently revised and, in the past few years, through the use of selective culture medium for stool isolation C fetus has been implicated as a frequent paghogen in children. There are three relatively distinct patterns of human C fetus infection. The first, most frequent, pattern of disease is enteritis which is usually uncomplicated and due to C fetus subsp jejuni. A second form of disease consists of focal infections, often associated with vasculitis and/or chronic bacteremia. These infections, due to C fetus subsp intestinalis, are seen most often in older, debilitated, or chronically ill men. The third pattern, perinatal infections causing abortion, prematurity, and neonatal meningitis, is the least frequent, but these infections are usually fetal to the fetus or infant and are also due to C fetus subsp intestinalis.

Group B streptococci are an important cause of infant septicemia and meningitis. A prospective study of group B streptococcal colonization in a 300-bed community hospital disclosed rates of 29% of 297 third-trimester women, 37% of 242 newborn infants, and 45% of 22 hospital personnel. Colonized parturients were more frequently black and anemic on admission for delivery. Infant colonization was statistically associated with a positive maternal genital culture, low birthweight, and prematurity. Nosocomial transmission of group B streptococci was strongly suggested by observations that 41% of colonized infants were born to culture-negative women and such infants became colonized later in their hospital stay than did colonized infants born to colonized women. Furthermore, hospital personnel working in the labor-delivery and nursery areas had a significantly higher prevalence of the organism than did personnel from other areas. Clearly, more information is needed about the epidemiology of group B streptococcal disease before appropriate and rational control measures can be recommended.

During the period January 1988 to December 1990, the overall incidence of infantile hydrocephalus in the south-western region of Saudi Arabia was 0.81/1000. The series comprised 61 infants affected by infantile hydrocephalus. The total number of live births in this period was 74,923. Hydrocephalus associated with spinal dysraphism (spina bifida cystica and encephalocoele) constituted 24 cases (39.3%), and there was aqueduct stenosis in 10 cases (16.4%). Nine cases (11.9%) were post-meningitic, and seven (14.8%) post-haemorrhagic. There was Dandy-Walker malformation in five cases (8.2%), three (4.9%) had congenital idiopathic hydrocephalus, two (3.3%) congenital toxoplasmosis, and one (1.6%) isolated Arnold Chiari malformation. There were congenital causes in 45 cases, 73.7% of all the cases in this series (incidence: 0.6/1000 births). Of the remaining 16 cases (26.3%) which were due to postnatal factors, seven (11.5%) were caused by acquired cerebral haemorrhage, only two of them being premature, and the other nine (14.8%) were due to meningitis. The data indicate the predominance of prenatal causes of infantile hydrocephalus and the relatively low contribution of extreme prematurity. This is possibly due to the high mortality of this group of infants in this region.

Five hundred and forty four cases of cerebral palsy were studied to find the etiology. Male to female ratio was 1.9:1. Prenatal, natal and postnatal factors were found in 42 (7.72%), 238 (43.75%) and 142 (26.1%) cases respectively. Only 79 (14.52%) cases were found to have more than one factor which could have contributed to brain damage. In 43 (7.9%) cases the prenatal, natal and postnatal history were normal and the cause was not known. Toxemia (1.29%) cases and microcephaly (1.84%) cases were the most common etiological factors in the prenatal category. Among the natal causes, birth anoxia was the most common etiological factor and was observed in 24.45% cases. Infections of the central nervous system comprised the major etiopathogenetic factors of the postnatal causes--11.95% cases had encephalitis, while 5.15% cases had meningitis. In cases where more than one etiology was present, the most frequent causes were a combination of prematurity or birth anoxia in association with toxemia, antepartum hemorrhage, prolonged labour, twins, forceps or caesarean delivery. Anoxia was consistently the most common etiological factor in those cases of monoplegia paraplegia, quadriplegia, diplegia, and ataxia, i.e. in 0.55%, 1.29%, 11.76%, 6.07% and 0.55% cases respectively. The present study reveals that majority of the cases were found to have natal or post natal etiology.

We examined 30 infants in whom cortical visual impairment was diagnosed during their first year of life to ascertain prognostic factors for the development of object vision, defined as the ability to recognize faces or hand-held toys. All patients were followed up for a minimum of 12 months. The most common causes of cortical visual impairment in the 30 infants were hydrocephalus in nine infants (30.0%), birth asphyxia or neonatal hypoxia in eight infants (26.7%), intracranial hemorrhage with or without hydrocephalus in seven infants (23.3%), and meningitis in five infants (16.7%). Lack of development of object vision was associated only with hypoxia (P = .013). Findings on ophthalmic examination, an abnormality in the visual pathway on computed tomographic or magnetic resonance scan, and seizures, hydrocephalus, intracranial hemorrhage, meningitis, cerebral palsy, developmental delay, prematurity, microcephaly, and hearing deficit, did not appear to be risk factors for the lack of development of object vision.

Risk factors, clinical syndromes and the case-fatality rates associated with Group B Streptococcus (GBS) infections in infants managed at the University of Rochester Medical Center during 1979 to 1989 were reviewed. Overall 92 episodes of early onset disease (EOD) and 54 of late onset disease (LOD) were diagnosed in 143 infants (3 infants with EOD presented later with LOD). About one-third of patients with EOD and controls were non-white compared with two-thirds of patients with LOD that occurred in racial minority groups. Prematurity and low birth weight were significantly more common in patients with invasive GBS disease than in controls. Eighty-three of 92 (90%) cases of EOD were detected during the first day of life and 10 of 54 (19%) cases of LOD occurred in infants older than 3 months of age. At the time of diagnosis 4% of infants with EOD were asymptomatic, 54% had respiratory disease, 27% had sepsis without a focus, 15% had meningitis and 1% had urinary tract infection or omphalitis. Among infants with LOD 46% had sepsis, 37% meningitis, 7% urinary tract infection, 6% osteomyelitis and/or septic arthritis and 4% cellulitis or pneumonia. Leukopenia and shift to the left were observed in 43 and 61% of episodes of EOD and in 28 and 57% of episodes of LOD, respectively. All infants were promptly treated with antibiotics and vigorous supportive therapy. The case-fatality rate was 13% in EOD and 0 in LOD.(ABSTRACT TRUNCATED AT 250 WORDS)

In the present study, brainstorm auditory evoked responses (BAER) were recorded in 68 at risk neonates discharged from the neonatal ICU of Safdarjung Hospital. The high risk group of 35 neonates included 13 neonates with multiple (3-4) risk factors and 22 neonates with single risk factors, viz., prematurity (less than 32 weeks) low birth weight (LBW) (less than 1500 g), hyperbilirubinemia requiring exchange transfusion, severe birth asphyxia, craniofacial malformations and sepsis with meningitis treated with amikacin for 3 weeks. The remaining 33 neonates were grouped in the low risk category who had only one of the following factors: prematurity (33-36 weeks)/LBW (1500-2000 g), hyperbilirubinemia requiring phototherapy, mild/moderate birth asphyxia, or sepsis treated with amikacin for 2 weeks. The test was performed at the mean conceptional age of 40.2 weeks (range 34-44 weeks) and involved determination of threshold of hearing as per presence of wave V. A normal response had wave V at 30 dB hearing level click stimulus at 50/sec from both ears or to 30 dB hearing level from one ear and 45 dB hearing level from the other ear. Thirteen neonates of the high risk group failed to produce a normal response (5 failed at 30 dB, 6 failed at 45 dB, and 2 failed at 75 dB hearing level). Forty six per cent of them had multiple high risk factors. All the low risk group neonates had normal threshold of 30 dB hearing level in the initial screening.(ABSTRACT TRUNCATED AT 250 WORDS)

Click-evoked otoacoustic emissions (OAEs) were recorded from both ears in two groups of neonates ranging in age from a few days to two months after birth. The first group consisted of 55 full-term neonates with normal developmental history and health status, including absence of middle ear disease and familial history of hearing loss. The second group consisted of 40 infants admitted to an intensive care baby unit for various pathological conditions (anoxia, prematurity, hyperbilirubinemia, meningitis). The method achieved 97% success in assessing cochlear function in the normal group; it was possible to identify a clear and reproducible response in all ears, except 3, at 70 dB SPL (i.e. approximately 30 dB nHL). The detection-threshold of OAEs was comparable to that measured in adult ears. Several babies from the second group produced no OAEs and were also tested by auditory brainstem responses (ABR): these infants demonstrated ABR thresholds higher than 30 dB nHL. OAEs provide an objective tool for a rapid and effective screening test for cochlear impairment in neonates.

Babies, on admission into a neonatal ward at the Lagos University Teaching Hospital, had their rectal swab specimens examined bacteriologically and screened for enteric bacterial pathogens over a one-year-period at two-week intervals. It was found that on the average there were 3 (9.68%) enteric bacterial pathogens out of an average of 31 admissions at each screening period. The enteric bacterial pathogens isolated included: non-typhoid salmonellae, which accounted for 55 (80.88%) isolates out of the 68 enteric bacterial pathogens, Salmonella typhi 2.94%, Shigella dysenteriae 2.94%, Shigella flexneri 4.41%, S. boydii 1.47%, S. sonnei 1.47%, Campylobacter jejuni 1.47% and Enteropathogenic Escherichia coli (EPEC) 2.94%. The main clinical conditions associated with those babies in whom the enteric pathogens were isolated included sepsis, prematurity, neonatal jaundice and tetanus. It is concluded that the enteric bacterial pathogens, even though they were not directly associated with diarrhoeal disease in the newborns in this study, might have contributed to other illnesses like sepsis and meningitis. It is also noteworthy that the enteric bacterial pathogens isolated sporadically from the babies could have been over-looked in view of the fact that it is not conventional to search for enteric bacterial pathogens in babies without diarrhoea on admission. Rectal swab investigations could provide additional information which might be of epidemiological importance in ill neonates in the clinical settings that prevail in developing countries.
