Two autopsy cases of congenital muscular dystrophy of Fukuyama type (F-CMD) were described. The first case was diagnosed clinically and pathologically as its typical case. Neither his family history nor the history of his prenatal period were contributory. He had suffered from muscle weakness and atrophy since his birth. Serum CPK was markedly elevated. EMG and muscle biopsy proved dystrophic changes of the skeletal muscles. In addition, he manifested mental retardation and attacks of convulsion. EEG failed to elicit remarkable changes, but PEG represented ventricular dilatation. He died of respiratory insufficiency at age 12. His postmortem examination showed variegated anomalies in the nervous system. Extensive micropolygyria was present in the cerebrum and cerebellum accompanied by adhesions between the bilateral cerebral hemispheres. Assymmetry of the longitudinal fibers was pointed out in the pontine base. Anterior horn cells were atrophic and moderately depopulated. On the other hand, the second patient was an atypical F-CMD case in symptoms, signs and pathology. His grand-mothers on both father's and mother's sides wee first cousins. His three siblings showed no similar disorders. His mother developed slight gestational toxicosis in the sixth and seventh months of pregnancy. His muscle weakness, contracture of the bilateral hip-joints and clubfoot had been observed since his birth. Physical and neurological examinations at age 6 showed deformity of the skull, myopathic face, macroglossia, high-arched palate, pigeon chest, scoliosis of the thoracic spine. In addition, generalized muscular atrophy, hypotonia and areflexia were recognized. Pseudohypertrophy of the muscles was absent. Sensation was intact to all modalities. Serum CPK and LDH were moderately increased.(ABSTRACT TRUNCATED AT 250 WORDS)

Eighty infants with cerebral palsy including monoplegia, diplegia, quadriplegia, hemiplegia, choreoathetosis, hypotonia with mental retardation and cerebellar ataxia, underwent Computed Cranial Tomography (CCT). Specific morphological anomalies such as ventricular dilatation with or without diverticulum, cortical atrophy, low density areas and calcifications, occur with varying frequency in each clinical groups. There exists a good correlation between the pathogenesis of the lesions, clinical data and CCT pictures.

A thirty-three-year-old male with Lowe's syndrome had cataract; nystagmus, buphthalmos, prominent frontal bossing, growth and mental retardation, aminoaciduria, proteinuria, rickets, areflexia, genu valgum, piercing cry and head-banging being among the presenting features. The rickety changes improved over a period of years with the administration of vitamin D2. Pathological changes include: (1) tubular damage in the kidneys and hypertrophies of Bowman's capsules; (2) small brain with ventricular dilatation with thickened meninges, small corpus callosum, small size of pyramidal tracts and medial leminisci, neurofibrillary tangles in the pyramidal cells of the Ammon's horn and frontal lobe; (3) eye changes of buphthalmos, congenital cataracts and thickening of Descemet's membrane; (4) testicular atrophy--both testes showing peritubular fibrosis with an increase of fibrous tissue in the interstitial tissue. Azoospermia was present linked with poor development of spermatogonia and spermatocytes. The lumina of the seminiferous tubules were filled with foamy exudate.

A 7-year-old girl was admitted with an unusual anomaly of hemimegaloencephaly associated with periventricular heterotopia manifesting as intractable seizures and mental retardation. Magnetic resonance (MR) imaging showed left hemispheric hypertrophy and left ventricular dilatation. Proton density-weighted MR imaging revealed a periventricular lesion isointense with gray matter. MR imaging is an effective method for diagnosing hemimegaloencephaly and heterotopia.

Nine children with congenital rubella syndrome were examined with respect to the relation between clinical symptoms and the findings of computed tomography (CT, 9/9 cases) and magnetic resonance imaging (MRI, 7/9 cases). All patients had deafness, and three had relatively severe sequelae in the central nervous system (CNS), such as mental retardation (MR), cerebral palsy (CP) or microcephaly. In four patients, dilatation of the lateral ventricles was found by CT; in four patients, low-density areas were noted in the periventricular white matter and/or the subcortical white matter; one patient showed a spotty calcified area in the lenticula. No abnormal findings were found by CT in other three patients. MRI in seven children demonstrated areas of prolonged T1 and T2 relaxation times in the white matter in all of them. In relation to clinical symptoms, five patients without dilatation of the lateral ventricles had no sequelae except deafness. On the other hand, in four patients with dilation of the lateral ventricles, three had MR, CP or microcephaly. This study showed that there was a close relation between the ventricular dilatation and sequelae with in CNS, whereas abnormal intensity areas in the white matter found by MRI were not related well to the sequelae of CNS.

A 14-year-old boy with mild mental retardation, myopathy, and nonobstructive hypertrophic cardiomyopathy (HCM) with clinical and histopathologic features consistent with lysosomal glycogen storage disease with normal acid maltase is described. The case illustrates the aggressive nature of the cardiomyopathy of this syndrome. This condition is associated with malignant ventricular arrhythmias, relentlessly progressive ventricular dilatation, dysfunction, and sudden death. It is important to recognize this unusual and malignant form of HCM to precipitate low early diagnosis by muscle biopsy. Patients with this condition would be excellent candidates for life-saving heart transplant as the myopathy and mental retardation are mild and nonprogressive. The underlying biochemical defect and mode of inheritance of this syndrome are unclear. However, a significant proportion are genetically related and thus, relatives may benefit from family screening.

In 1964, Sotos and co-workers defined a syndrome of advanced height and bone maturation, dating from birth, mental deficiency and unusual craniofacial appearance with acromegaloid features. About 200 cases have subsequently been reported, more often in males. Occurrence is sporadic, but inheritance may be dominant autosomal. The aetiology is unknown. A two- and a half-year-old boy with Sotos's syndrome is described. He was the first-born child of non-sanguineous healthy parents. The family history revealed no congenital abnormalities and no mental retardation. The proband was born at 36 weeks of gestation with a weight of 4100 g (> P97), length of 53 cm (> P90) and occipital-frontal circumference of 36 cm. His postnatal sornatic linear growth was excessive taking a curve above the 97th percentile. Skeletal maturation and bone age were accelerated. Premature eruption of teeth was observed. Clinical features included macroencephaly, dolichocephaly with a prominent forehead, down-slanting palpebral fissures, hypertelorism, high-arched palate and large hands and feet. His mental deficiency was mild (IQ = 60) with delay of early psychomotor development and expressive language. His karyotype was normal. The CT brain scans revealed mild ventricular dilatation and some cortical atrophy. Electroencephalographic records showed localised theta activity. Endocrinological and metabolic studies failed to show andy definite abnormality.

X-linked hydrocephalus is a genetic form of hydrocephalus that frequently occurs in females. It is characterized by ventricular dilatation, mental retardation, deformity of the thumb and spastic paraparesis. Recently, 23 different mutations of the gene for the neural cell adhesion molecule, L1CAM, located at chromosome region Xq28, have been reported, 16 of which were detected in families with X-linked hydrocephalus. We sequenced the coding region of the L1CAM gene of patients from two different families with X-linked hydrocephalus and found a novel mutation at nucleotide residue 1963 in one family. This mutation from adenine to guanine results in an amino acid change from lysine to glutamic acid at residue 655 of the L1CAM protein, which belongs to the fibronectin type III domain. We report another method of the rapid identification of the mutation based on the polymerase chain reaction. This mutation was not detected among 70 X chromosomes from a healthy population. Ours is the first report demonstrating this gene mutation in X-linked hydrocephalus in an Asian population. Our findings further emphasize the evolving genotypic heterogeneity in X-linked hydrocephalus.

In 1972, Fried described a large Scottish family affected by X linked mental retardation (XLMR), hydrocephalus, and mild facial dysmorphism. The phenotype has considerable similarity to the MASA syndrome, which results from mutations of the L1CAM gene in Xq28, and this family has since been assumed to be an example of this condition. We have reinvestigated the family for linkage to X chromosome markers, and obtained additional clinical information on surviving affected subjects. The phenotype in these patients has evolved into a distinctive syndrome, with severe mental retardation (MR), spastic diplegia, ventricular dilatation, and calcification of the basal ganglia. Linkage to Xq28 markers has been excluded, suggesting that Fried syndrome is not allelic with MASA syndrome. Two point and multipoint linkage analysis indicates that the gene for this condition lies within the interval KAL-DXS989 in Xp22. We propose the designation Fried syndrome to emphasise the disorder's distinctive phenotype.

Fourteen children (of Arab ethnic origin) with Sotos syndrome are described. They were referred to King Khalid University Hospital, Riyadh between July 1992 and June 1997. Their phenotypic characteristics were compared with established diagnostic criteria. There was a male:female ratio of 1.3:1 and a high rate of consanguinity (36%) among parents. At birth, 54% were large and about one-third showed increased height and occipitofrontal head circumference (OFHC). The neonatal histories revealed respiratory and feeding problems in 21%, followed later by delayed motor milestones and speech development in 57%. During childhood, weight, height and OFHC increased further to > 97th centile in 71%, 71% and 93%, respectively. A seizure disorder affected 43%, and 75% had mental retardation (IQ < 70). A non-specific EEG abnormality was found in half of those with seizures. Cranial CT/MRI showed ventricular dilatation in 15% and one patient had corpus callosum dysgenesis. Abdominal ultrasound revealed hydronephrosis in two patients. Radiological cephalometric measurements showed relative prognathism in cases of Sotos syndrome compared with controls (p = 0.003). The study highlights the importance of considering Sotos syndrome in children who present with psychomotor delay.
