Liver fibrocystic disease (LFCD), characterized by dilatation of the intrahepatic bile ducts and variable degree of fibrosis, can be present alone or as part of many syndromes, such as Bardet-Biedl syndrome (BBS), Meckel syndrome, Jeune asphyxiating thoracic dysplasia, and Fraser-Jequier-Chen syndrome. We report two cases of LFCD and polydactyly with features similar, but not diagnostic of, BBS. Patient 1 was an 18-month-old boy with mental retardation, polydactyly, chronic renal failure, convergent strabismus, and hepatic fibrosis. Patient 2 was a male neonate with LFCD and polydactyly. Their manifestations could not be diagnosed as any of the previous mentioned entities. Difficulties in the early diagnosis of BBS have been previously reported and this could explain the clinical variability and heterogeneity of manifestations at the time of diagnosis. On the other hand, the existence of liver abnormalities in association with BBS has been previously described, but is rare. Our patients' malformations might represent a new entity where autosomal recessive inheritance is probable, but other patterns cannot be ruled out.

We report on a young male with mental retardation, slightly upslanting palpebral fissures, strabismus, high-arched palate, retrognathia, and flat feet. Cytogenetic analysis in addition to fluorescent in situ hybridization (FISH) and comparative genomic hybridization (CGH) showed the presence of a chromosome 10p11.2-->p12.2 duplication. Karyotypes of the parents were normal. Comparison of the clinical findings observed in the present patient with those observed in other reported cases with duplication 10p suggest that the presence of high arched/cleft palate and retrognathia may be related to the 10p11.2-->p12.2 duplication. Also, no critical region for the trisomy 10p syndrome has been delimited.

The Dubowitz syndrome is a rare, autosomal recessive disorder including intrauterine growth retardation, craniofacial abnormalities, mental retardation and eczematous skin eruption. Ocular problems occur in about 20%: strabismus, blefarophimosis, ptosis, telecanthus and epicanthal folds being the most frequent ones. We present a three years old girl, diagnosed with Dubowitz syndrome, with sudden visual loss due to bilateral cataract.

A boy with an unspecific symptomatology consisting of mental retardation, strabismus, hypotonia and mild ataxia was diagnosed with a congenital disorder of glycosylation (CDG). Neither cerebellar atrophy nor dysmorphic features were present. The serum transferrin band pattern obtained by isoelectric focusing(IEF) showed a strongly elevated disialotransferrin band together with only slightly elevated asialotransferrin, thus a type I pattern. This is a new CDG classified CDG-x since CDG-la, -b, -c, -d and -e were excluded. Quantitative differences to the type 1 pattern of a CDG-la patient with a moderate to severe course were confirmed by densitometric evaluation of the gels and by SDS gel electrophoresis. Liver biopsy showed lysosomal inclusions suggesting a pre-Golgi defect. This patient's case supports the approach to include isoelectric focusing of serum transferrin in the diagnostic work-up of patients with unexplained symptoms.

A cross sectional survey was conducted in Central Region, Ghana to determine the prevalence of children with disabilities. Forty-seven (1.8%) out of a total of 2,556 children under fifteen years of age had disabilities. About a third, had difficulty with movement of which post poliomyelitis infection disability formed the majority. Twelve children (25.5%) had difficulty with hearing and speech (deaf and dumb). Three children were reported as having epilepsy and 2 others had mental retardation. There was no case of total blindness, however, two children complained of poor vision and three others had a squint. Other disabilities identified, included one child each with kyphosis (hunch back), hydrocephalus (very large head) and extensive facial scars from burns. Disability was more common among children who had not been immunized or who did not have immunization card at the time of interview. The prevalence of disability was higher among female children in the rural community and in children with no formal education. Prevalence of disability increased with age. The prevalence of disability was 14.4 per 1,000 for children (1-5) years, 16.6 per 1000 for children (6-9) years and 3.7 per 1,000 for (10-15) years age group. Younger children had better immunization status and lower disability rates. Thirty percent of the children with disability said they were experiencing discrimination especially among the female children. This study has demonstrated that there is a need to intensify the preventive efforts at reducing the problem of childhood disability and to increase public support to the disabled children by avoiding discrimination and encouraging education and training of the disabled children.

To assess the clinical impact of microcephaly among children with developmental disabilities, we reviewed the charts of 1393 consecutive patients from birth to 5 years of age referred to our child development center. Comparisons were made between normal and low IQ microcephalic patients and between children with cerebral palsy with and without small head circumference. Microcephaly was detected in 15.4% of patients. Although mental retardation was more common among microcephalic children (P < .001), almost half had normal intelligence. Prematurity (P < .001), perinatal asphyxia (P < .001), small for gestational age (P < .001), respiratory distress syndrome (P < .001), and brain hemorrhage (P < .001) were associated with microcephaly. Hypotonia (P < .001) and spasticity (P < .001) were the most common neurologic findings. Cerebral palsy (P < .001), growth retardation (P < .001), epilepsy (P < .001), and strabismus (P < .001) were the main associated diagnoses found. Mental retardation was significantly more common among microcephalic patients with cerebral palsy than among normocephalic ones (P < .0004). Microcephaly is common among children evaluated for developmental disabilities. Many of these patients have normal or borderline IQ. Of several perinatal conditions associated with later microcephaly, respiratory distress syndrome and intraventricular hemorrhage show the strongest correlation. Mental retardation is not a risk factor for other neurologic complications in microcephalic children. However, in children with cerebral palsy, microcephaly is a risk factor for mental retardation.

The authors report a case of de novo duplication 1q32-qter present in a patient with dysmorphic syndrome and developmental delay. This article describes the eighth case of partial trisomy 1q32-qter "pure", without chromosomal abnormalities. In the literature, a dysmorphic "syndrome" is described for trisomy 1q32-qter: hypertelorism, low set and malformed ears, prominent forehead, long philtrum, antimongoloid slanting, foot and digital malformations, cardiovascular abnormalities, urogenital abnormalities, and mental retardation. The ocular defects described in previously reported cases include: cataract, strabismus, hypoplasia of the optic disk, microphthalmia, epicanthal folds, ptosis, persistent tunica vasculosa lentis, and hyaloid vessels, but this seems to be nonspecific of this chromosomal abnormality.

We present the clinical, electroencephalographic, neuroimaging (brain magnetic resonance image - MRI and spectroscopy by MRI) and cytogenetic findings of a young male patient with a rare cytogenetic anomaly characterised by a de novo 46,XY,r(20)(p13q13.3) karyotype. He presents with mental retardation, emotional liability, and strabismus, without any other significant dysmorphies. There are brain anomalies characterised by corpus callosum, uvula, nodule and cerebellum pyramid hypoplasias, besides arachnoid cysts in the occipital region. He had seizures refractory to pharmacotherapy and long period of confusional status with or without a motor component. The authors recognised that the EEG pattern was not fixed but changed over time, specially for bursts of slow waves with great amplitude accompanied or not by sharp components, and bursts of theta waves sharply contoured. Previously, epilepsy solely has been assigned to region 20q13. However, the important structural cerebral alterations present in our case has not been reported associated to such chromosomal abnormality and may indicate possible new chromosomal sites where such atypical neurological characteristics could be mapped.

We identified an oligophrenin 1 (OPHN1) gene mutation in a family with five brothers affected by a recognizable pattern of clinical and neuroradiological hallmarks. The distinctive phenotype comprised moderate to severe mental retardation, myoclonic-astatic epilepsy, ataxia, strabismus and hypogenitalism. Neuroimaging displayed fronto-temporal atrophy with rostral enlargement of the lateral ventricles, lower vermian agenesis and asymmetric cerebellar hypoplasia. Mutation analysis of the OPHN1 gene on Xq12 disclosed a genomic deletion of exon 19 causing a frameshift. Notably, OPHN1 mutations have been previously reported as a rare cause of non-syndromic X-linked mental retardation. Our findings, however, indicate that OPHN1 mutations result in a recognizable syndrome. In addition, identification of OPHN1 as a further gene associated with epileptic seizures will help to unravel aetiologic factors of epilepsy.

To get a comprehensive picture of prematurity and neonatal death or survival, all factors on the maternal and fetal records that might be pertinent were recorded. This information, having to do with factors such as age, gravida of the mother, blood group incompatibility, period of gestation, weight at birth, type of delivery, medication and anesthesia administered to the mother, is presented in tabular form. In the study of perinatal mortality it was noted that failure to establish normal pulmonary ventilation is the most common cause of death in the neonatal period. Maternal history of relative infertility, that is, previous abortions, stillbirths and premature deliveries, was the most impressive finding in the stillborn series. In the follow-up study of premature infants who survived the neonatal period, 8.5 per cent were found to be severely handicapped. In four cases the handicap was due to congenital anomalies, in two others probably to infection, leaving 12 with complications possibly ascribable to prematurity. Six of these had retrolental fibroplasia as a major handicap. In seven, mental retardation was the presenting problem. Most of the handicapped children had multiple handicaps, which included spasticity, delayed motor development, strabismus, etc. The incidence of the necessity for corrective measures for feet and legs appeared relatively high. In general, survivors compared favorably with the rest of the childhood population. Complications and twinning were associated inordinately often.
