Meningoencephalitic syndrome can be caused by many infective agents. Over a period of 13 years, 15 of 170 cases of neurocysticercosis (NCC) presented as meningoencephalitis. The basis of diagnosis of NCC was positive subcutaneous nodule histopathology (4), CT scan (9) and autopsy (3) findings. The age of the patients ranged from 7-68 years (mean 32). Fever was encountered in 12, altered sensorium in 7, seizures in 10 and abnormal behaviour in 3 cases. All cases had papilloedema. Focal neurological signs included optic atrophy, lateral rectus palsy, hemiplegia, internuclear ophthalmoplegia and cerebellar ataxia. Cerebrospinal fluid was abnormal in 8 of 13 cases, leading to a suspicion of tuberculous meningitis. Twelve patients improved with therapy. Three cases ended fatally and autopsy confirmed the diagnosis.

We report on an infant male who presented with microcephaly of prenatal onset, schizencephaly, decorticated disturbance of the neurological function, congenital optic atrophy, abnormal eye movements and nystagmus. In addition, he had a skeletal dysplasia with predominant acromelic involvement and a renal disease characterized by both nephritic and nephrotic changes. The natural history of his condition included severe postnatal failure to thrive, lack of development of psychomotor milestones, intractable seizures, terminal renal insufficiency with early death. Such spectrum of phenotypic abnormalities has never been reported before and we suggest that it may represent a new syndromic entity. The differential diagnosis with the oculo-skeletal-renal syndromes, with the osteodysplastic primordial dwarfism of the Taybi-Linder type and with the Hutterite cerebro-osteo-nephrodysplasia, is discussed.

Observation of neurosarcoidosis in a thirty-year-old black female characterised predominantly by bilateral facial nerve paralysis gave rise to a review of literature since 1978 and also to a comparison with an early study in 1963. As described 1963 the clinical picture is characterized by increased protein content of the CSF (33.8%), facial nerve paresis (25.5%), pleocytosis (23%), diabetes insipidus (21%), hemiparesis (17.2%), organic psychosis (16.9%), papilloedema (15.5%), ataxia (13%), convulsive seizures (12.5%), optic atrophy (12.5%), loss of hearing (12.2%), nystagmus (8.6%) and numerous other symptoms more rarely found. This corresponds to the symptoms of chronic basal meningitis with an infiltration in the neighbouring structures of brain and less frequently the spinal cord. In only 58.7% of the cases (presumably at the onset of sarcoidosis) was the bronchial tract (or the lungs) affected, in 11.5% the skin or the eyes. Although the clinical picture is clear enough the etiology has yet to be determined. Evidence of a pathogen or a pathogenic agent (analogous to berylliosis) has never been established to date. On the other hand there are some indications of a disturbance in the immune system, perhaps of a particular genetic foundation since sarcoidosis strikes black patients with conspicuous frequency. There exist more cases in one family. Exceeding expected random distribution, many patients have the HLA-Factor B 8 (on the chromosome 6) and DR 3. The Kveim-Test was in 71 cases positive, in 12 cases negative. The possibilities of carrying out studies of CSF - analogous to the studies of bronchial lavage - in the most cases of neurosarcoidosis have not been exhausted as to determine the activity of the T-lymphocytes, the interleucines, the angiotensin-converting enzyme while the Gallium 67 scintigraphy and other methods to determine the non-specific activity of the inflammation. The efficiency of the treatment with corticosteroids (Prednison or Triamcinolonacetonid) depends of the phase of the inflammatory process. 12% of the registered cases died.

Recent electrophysiologic studies have focussed attention on the X-linked adrenoleukodystrophy (ALD) and its myeloneuropathic variant. No organized studies are, however, yet available on its relatively recently described neonatal variant. We conducted electroencephalographic, electroretinographic and evoked response studies in 2 patients with neonatal ALD. In one patient, an infant, initial EEG, hypsarrhythmic in waking and somewhat periodic in sleep, showed dramatic improvement on ACTH therapy accompanied with a seizure-free status. The EEG and clinical improvement, however, were temporary. No improvement occurred following pyridoxine therapy. Her electroretinogram (ERG), visual evoked responses (VERs) and far-field short latency brain-stem auditory evoked responses were also abnormal. The latter studies probably reflected photoreceptor degeneration, optic nerve involvement, cochlear and/or auditory nerve involvement respectively in neonatal ALD. The other patient, a 3.5-year-old girl, also had an EEG characterized by a moderate- to high-amplitude slow background activity and high-amplitude multifocal, generalized or periodic paroxysmal discharges, but presence of some better formed theta frequencies in background activity precluded a hypsarrhythmic label on her EEG. Her ERGs and VERs were totally extinct but in contrast to the first patient, she had clear-cut optic atrophy and retinitis pigmentosa on ophthalmological examination.

A newborn is reported with diffuse gliomatosis involving the cerebral hemispheres, the brainstem and the cerebellum. The presenting signs were paucity of spontaneous movements except for multifocal clonic seizures, absent response to sensory stimuli and optic atrophy. A CT scan suggested agyria. The child expired on the seventh day. Autopsy disclosed diffuse gliomatosis affecting both cerebral hemispheres, the brainstem and the whole cerebellum, but excluding the spinal cord. Neuronal loss was unusually severe in all the affected areas. The genitals were ambiguous, an association not explained by the cerebral pathology. The karyotype was 46XY (male pseudohermaphroditism). This is probably the first reported instance of gliomatosis cerebri in a newborn.

A 19-year-old woman with long-standing sensorineural deafness, bilateral cataracts and mild clumsiness, presented with acute focal edema in the left temperoparieto-occipital area which required surgical decompression as a life-saving measure. Investigation revealed a persistent lactic acidemia and evidence of many ragged red fibres in a skeletal muscle biopsy specimen, suggesting a diagnosis of mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS) syndrome. The patient developed two further stroke-like episodes over a short period. One sibling died at the age of 14 years with a progressive neurological illness characterised by seizures, bilateral optic atrophy, ataxia, myoclonus and progressive dementia. The diagnosis of MELAS syndrome should be considered in young people presenting with stroke-like episodes that fail to conform to a given vascular territory, particularly if they have long-standing minor neurological abnormalities or a family history of obscure early onset neurological disease. The different clinical pictures in the two affected siblings in this family suggest that MELAS syndrome is part of a spectrum of inherited mitochondrial cytopathies rather than a discrete disease entity.

There are several clinically distinct forms of neuronal ceroid lipofuscinosis whose presentation and pathology are usually homogeneous within families. Several atypical variants have also been reported. We have studied an inbred sibship in which neuronal ceroid lipofuscinosis appeared to present in two completely different ways. In the proband, the course was compatible with a somewhat atypical juvenile variant. Ataxia and spasticity started at 4.5 years, followed by blindness with optic atrophy, intractable seizures, dementia, and death at 14 years. Atypical features included areflexia, hypotonia, and ataxia. Electron microscopic studies of her skin and her rectal ganglion cells showed lucent, dense, and fingerprint inclusions that were also found in the central nervous system at autopsy. Her brother and sister developed difficulty walking at ages 8.5 and 10.5 years and are alive at 24 and 18 years. They presented with slowly progressive spinocerebellar degeneration with sensorimotor neuropathy without dementia, seizures, or visual impairment. Lysosomal enzymes and lipoprotein analysis were normal in all three siblings and their parents. Elevated dolichol in the urine and lucent, dense, and fingerprint inclusions in skin, cutaneous nerve, buffy coat lymphocytes in both siblings and in the sural nerve of the brother suggest that their disease may represent a novel phenotype of neuronal ceroid lipofuscinosis. While it is possible that two different recessive genes may be segregating in this consanguineous family, we cannot dismiss the possibility that variability of gene expression may account for the divergent phenotypes.

We have studied the clinical presentation and course of a chronic inflammatory disease occurring in childhood and observed in 30 patients. The first symptoms were generally present at birth, except in a few patients where they were first noticed in early infancy. All the patients had the association of three main symptoms: neurological, cutaneous and articular. The skin rash was the first symptom observed in all the patients and looked like a chronic non pruritic urticaria varying during the day. The articular manifestations involved knees, ankles and feet, elbows, wrists and hands unaffecting the other joints. They could be mild giving arthritis during flare-ups or severe with major radiological modifications affecting the epiphysis, metaphysis and growth cartilage. The neurological manifestations were characterized by a chronic meningitis and symptoms indicating meningeal irritation: headaches, seizures, spasticity of legs. Most patients had a cerebral atrophy and a low IQ. Sensory organ involvement occurred progressively during the follow-up: ocular inflammation with optic atrophy, deafness and hoarseness. Common morphological features characterized these patients with short stature, head enlargement, saddle back nose and short and thick extremities with clubbing of fingers. The course was that of a chronic inflammatory disease with numerous flare-ups associating fever, splenomegaly and adenomegaly. Except for a high level of eosinophils in blood, CSF and tissues, the biology was non specific and only exhibited features of inflammation. Except for two families, the disease was sporadic. A high frequency of prematurity with features resembling a foetal infection was observed but no proof of a possible causal virus has so far been found so that etiology remains unknown.

Biotinidase deficiency is the primary defect in most individuals with late-onset multiple carboxylase deficiency. We have reviewed the presenting clinical features of 31 children with the disorder. Seizures, either alone or with other neurological or cutaneous findings, are the most frequent initial symptom observed. Other neurological symptoms, such as hypotonia, ataxia, hearing loss, optic atrophy, and developmental delay, are seen, in addition to skin rash and alopecia. The disorder is also characterized by ketolactic acidosis and organic aciduria. Biotinidase activity may be diagnosed using a simple, rapid, semiquantitative colorimetric procedure. Samples of whole blood spotted on the same filter paper used by most states to screen for phenylketonuria and other inborn errors of metabolism may be sent to an appropriate reference laboratory. None of the common anticonvulsants or sedatives used to treat newborns and children interfere with the test. Because biotinidase deficiency can be treated readily with biotin, this disorder should be considered in children with infantile seizures, especially in the presence of other characteristic neurological or cutaneous features.

We studied a patient with somatic growth failure with easy fatigability, myopathy with mitochondrial abnormality, increased lactate and pyruvate in blood and CSF, mental retardation, seizure, myoclonus, deafness, cerebellar ataxia, and blindness with macular degeneration and optic atrophy. Pathologic findings included multiple brain infarctions and massive calcification in the basal ganglia. Biochemical studies of isolated mitochondria revealed decreased oxygen consumption in skeletal muscle, diaphragm, and brain, suggesting an abnormality in the respiratory chain.
