[Tuberculous meningitis: value of neuro-imaging for early diagnosis].
The authors report a case of tuberculous meningoencephalitis diagnosed in a 20-month-old boy with severe neurological sequelae. Most cases of the tuberculous meningitis occur in children less than 3 years old. The mortality rate and incidence of sequelae are greater without early treatment. Imaging has a great impact in the early diagnosis of this disease. In Europe, the increasing incidence of tuberculosis underscores the need to diagnose tuberculous meningitis without delay in children in order to provide a prompt and appropriate treatment.

[Cerebellar vermis hypoplasia with extracerebral involvement (retina, kidney, liver): difficult to classify syndromes].
UNLABELLED: Congenital cerebellar vermis hypoplasias diversely associated with retinopathy, nephropathy and hepatopathy are rare syndromes of uncertain nosology. We report three new cases. CASE REPORTS: Case 1. A 3-month-old boy presented a brief nystagmus. At the age of 2 years, he had facial dysmorphia, hypotonia, ataxia, ocular motor apraxia and neurodevelopmental impairment with cerebellar vermis hypoplasia. The electroretinogram showed asymptomatic retinal involvement. At the age of 6 years, he developed chronic renal failure. The diagnosis of familial juvenile nephronophthisis was made by detection of a large homozygous deletion of the NPH1 region. Case 2. A term newborn boy presented apnea, tachypnea, hypotonia, nystagmus, ptosis, lack of visual contact and hepatomegaly. He had facial dysmorphia, bilateral optic coloboma with chorioretinal dysplasia and cerebellar vermis hypoplasia. There were cysts in the kidneys with increased echogenicity and lack of demarcation between the pyramids and the cortex. The liver was hyperechoic with fibrosis. At the age of 15 months, the child had severe developmental delay. He had bouts of fever. A search for a large homozygous deletion of the NPH1 region was negative. Case 3. A term newborn girl presented difficulty to suck, cyanosis, hypotonia and ptosis. Later, the child had a developmental delay. At the age of 6 years, she developed chronic renal failure (nephronophthisis). At the age of 23 years, she presented divergent strabismus, ataxia, mental retardation, slow ocular pursuit and facial dysmorphia. The neuroimaging showed a cerebellar vermis hypoplasia. A search for a large homozygous deletion of the NPH1 region was negative. CONCLUSION: The diagnosis of cerebellar vermis hypoplasia requires searching for retina, kidney and liver involvement. The large homozygous deletion of the NPH1 region has to be investigated if typical familial juvenile nephronophthisis is associated. Because cerebellar vermis hypoplasia with extracerebral involvements (retina, kidney, liver) is part of many different closely related syndromes, a clear molecular classification is necessary for accurate genetic counselling and an early prenatal diagnosis.

Profiles of nursing home residents with multiple sclerosis using the minimum data set.
This paper profiles nursing home residents with multiple sclerosis (MS) at the time of admission, including sociodemographic characteristics, health status measures, and treatments received. Admission assessments from the Minimum Data Set are used to create these profiles of residents with MS. There are 9,013 admission assessments in the MDS for residents with MS between June 22, 1998 and January 17, 2000 analyzed for this study. Residents with MS are distinctly younger at admission than most nursing home residents, averaging 57.98 years of age. Recently admitted residents with MS are more physically dependent than other nursing home residents and tend to have limited range of motion and loss of voluntary movement About one in three newly admitted residents with MS had some degree of impaired cognitive function. Over one third of residents with MS were depressed at admission, yet only 11.7% of recently admitted residents with MS were evaluated by a licensed mental health specialist This prompts concem about the psychosocial well-being of MS residents in nursing homes.

[Feingold syndrome].
BACKGROUND: Feingold syndrome is a combination of hand and foot anomalies, microcephaly, tracheo-esophageal fistula, esophageal/duodenal atresia, short palpebral fissures and developmental delay. The most frequent physical findings are clinodactyly of the second and fifth fingers with absent or hypoplastic middle phalanges, and syndactyly of the toes. Inheritance is autosomal dominant (MIM number 164280) with full penetrance concerning hand anomalies, variable expressivity and great intrafamilial variability. CASE REPORT: We report the case of an African boy with duodenal atresia, microcephaly, brachymesophalangy of the second and fifth fingers, unilateral thumb hypoplasia, bilateral syndactyly of toes 2-3 and amesophalangy of the toes. Karyotype was normal. No other member of the family was affected. A fresh mutation is possible. CONCLUSION: Brachymesophalangy affecting mainly the second and fifth fingers and amesophalangy of the lateral toes are cardinal clinical findings in Feingold syndrome. These clinical findings define the syndrome of brachydactyly A4-Temtamy type (MIM 112800), suggesting that brachydactyly A4 would be a partially expressed Feingold syndrome. The incidence of esophageal/duodenal atresia is 29%, including all the known cases. All karyotypes of reported patients were normal.

[Severe forms of eosinophilic meningitis in infants of Mayotte. Apropos of 3 cases].
BACKGROUND: Eosinophilic meningitis caused by Angiostrongylus cantonensis is widespread in Southeast Asia and the Pacific islands. Adults develop transient meningitis with a benign course, whilst severe or fatal disease may occur in pediatric patients. CASE REPORTS: Three infant girls, aged 8 to 11 months, living on the island of Mayotte, developed fever, hypotonia, coma (2 cases), and, for one of them, seizures. Eosinophilia was detected in the peripheral blood and cerebrospinal fluid. Secondary, flaccid quadraplegia (1 case) or paraplegia (2 cases) with absence of deep tendon reflexes, urinary retention and anal incontinence were noted. Three patients had autonomic dysfunction. Computerized tomography showed enlarged ventricles and cerebral subarachnoid spaces. One patient had sequelae. Two patients could not be followed. Retrospectively, the diagnosis of angiostrongylus infection was established for two infants by a serological study. CONCLUSION: We report three new cases of infants with severe Angiostrongylus cantonensis infection in the French island of Mayotte (Comoro Islands). In this Indian Ocean area, eosinophilic meningitis seems to occur exclusively in infants and with severe radiculomyeloencephalitic forms.

[Pseudo-periodic disease with hyperimmunoglobulinemia D: a never-ending story with probable prenatal onset].
UNLABELLED: Diagnosis of inflammatory non-infectious diseases with a neonatal onset is often retrospective. It may lead to aggressive and iatrogenic procedures. PATIENT: A 6-year-old boy was suffering, since birth, from recurrent febrile attacks including rashes, gastrointestinal manifestations and inflammatory joint involvement. This syndrome, partially improved with steroids, could have been of antenatal onset. Since the age of 4 years, the patient is considered as having hyper-IgD syndrome (HIDS). DISCUSSION: HIDS must be distinguished from familial Mediterranean fever. Patients suffer from recurrent fever concomitant to inflammatory joint involvement, abdominal distress, skin lesions, swollen lymph nodes and hepatosplenomegaly (especially seen in children). All patients have high serum IgD (> 100 UI/mL) and IgA levels. Nevertheless, a high IgD level is not specific. Our case could also be part of the CINCA (chronic, infantile, neurological, cutaneous and articular) syndrome, which includes similar early manifestations associated with a constant neurological and frequent ophthalmological involvement and epiphyseal changes; to date, these last three manifestations are not present in our patient. CONCLUSION: HIDS and CINCA syndrome are not known to be modified by any effective therapeutic agent. When presenting at birth, these inflammatory diseases must be considered as entities with a rarely described potential severity.

[Angiostrongylosis in infants in Reunion and Mayotte. Apropos of 3 cases of eosinophilic meningitis including 1 fatal radiculo-myeloencephalitis with hydrocephalus].
BACKGROUND: Eosinophilic meningitis caused by Angiostrongylus cantonensis is widespread in Southeast Asia and Pacific islands. Adults develop a transient meningitis with a benign course but severe or fatal disease may occur in pediatric patients. CASE REPORT: Case 1. A 11-month-old boy living in Mayotte island was hospitalized a few days with fever and skin rash following by seizure, coma, flaccid quadraplegia, absence of deep tendon reflexes, urinary retention and anal incontinence. Eosinophilia was observed in peripheral blood and cerebrospinal fluid. He further developed a triventricular hydrocephalus treated by ventriculoperitoneal shunt. The child died 3 weeks later. A serodiagnosis of angiostrongylus infestation was restrospectively established. Case reports 2 and 3.-Two infants, 10 and 11-month-old-boys, living in Reunion island, developed fever and vomitings, irritability and, for one of them, unilateral sixth cranial nerve palsy. There was eosinophilia in the peripheral blood and in the cerebrospinal fluid. All symptoms progressively disappeared with complete recovery. The suspected diagnosis of angiostrongylus infestation was confirmed by the serology. CONCLUSION: We report the first case of Angiostrongylus cantonensis infection in the French island of Mayone (Comoro Islands) and we confirm the presence of this disease in Reunion island. In this Indian Ocean area, eosinophilic meningitis occurs most of the time in infants with sometimes severe radiculomyeloencephalitic forms.

[Angiostrongylus in the infant at Reunion and Mayotte. Apropos of 3 cases of eosinophilic meningitis including 1 fatal radiculomyeloencephalitis with hydrocephalus].
BACKGROUND: Eosinophilic meningitis caused by Angiostrongylus cantonensis is widespread in Southeast Asia and Pacific islands. Adults develop a transient meningitis with a benign course but severe or fatal disease may occur in pediatric patients. CASE REPORT 1: A 11 months old boy living in Mayotte island was hospitalized some days after fever and skin rash with seizure status, coma, flaccid quadriplegia, absence of deep tendon reflexes, urinary retention and anal incontinence. Eosinophilia was observed in peripheral blood and in the cerebrospinal fluid. Secondary, he developed a triventricular hydrocephalus treated by a ventriculoperitoneal shunt. After 3 weeks, the child died. Retrospectively, the diagnosis of angiostrongylus infection was established with the help of serology. CASE REPORTS 2 AND 3: Two infants, 10 and 11 months old boys, living in Reunion island, developed fever and vomitings, irritability and, for one of them, a unilateral sixth cranial nerve palsy. There was eosinophilia in the peripheral blood and in the cerebrospinal fluid. All symptoms progressively disappeared with complete recovery. The suspected diagnosis of angiostrongylus infection was confirmed by the serology. CONCLUSION: We report the first case of Angiostrongylus cantonensis infection in the French island of Mayotte (Comoro Islands) and we confirm the presence of this disease in Reunion island. In this Indian Ocean area, eosinophilic meningitis occurs most of the time in infants with sometimes severe radiculomyeloencephalitic forms. The origin of these occasionally massive infections is the giant African snail Achatina fulica. For a child with meningitis living in Reunion or Mayotte, or coming back from these 2 islands, Angiostrongylus cantonensis infection must be evoked, especially if there is a blood eosinophilia. Since efficiency of antiparasitic treatment is nowadays not proved, information must be given to people living in exposed areas in view to limit incidence of this disease.

[Multiple cerebral telangiectasias. Apropos of an anatoma-radioclinical case].
UNLABELLED: Telangiectasias are vascular malformations corresponding to dilated capillary separated by nervous parenchyma. They are generally asymptomatic and discovered during autopsy. CASE REPORT: We describe the case of a 2-year-old girl who was admitted for drowsiness and vomitings with craniomegaly and right hemiparesis. The cerebral imaging demonstrated large amounts of calcium in the region of pons and left thalamus with a contrast enhancement throughout these calcifications. The thalamic lesion was cystic with obstruction of the third ventricle and hydrocephalus. There were multiple calcifications scattered throughout the basal ganglia and the white matter. The latter had a low density on CT and high signal intensity on MRI (T2). The cerebral angiographic study showed a blush in the pons and the thalamus. Clinical course was fluctuating or intermittently progressive. Finally, in spite of radiotherapy and oral corticosteroid treatment, the child became quadriparesic with oculomotor palsy. She suddenly died at age 4 years and 6 months from a hemorrhage of the pons. Neuropathological study showed two clusters of telangiectasias with calcifications in the pons and the thalamus. Other calcified vascular malformations were seen in the white matter and the basal ganglia. Near the lesions, astrocytar gliosis and edema were observed. The white matter was malacic with isolated calcifications. CONCLUSION: Cerebral telangiectasias may be multiple and may produce severe neurologic disorders, occurring in infancy with fluctuating clinical course. Arteriography may show these usually cryptic vascular malformations. This diagnostic should be kept in mind in view to the neuroradiological aspect we report here.

In situ assay of acid sphingomyelinase and ceramidase based on LDL-mediated lysosomal targeting of ceramide-labeled sphingomyelin.
The activity of lysosomal sphingolipid hydrolases is usually estimated in vitro from complex assays on cell lysates under artificial conditions including the presence of detergents and substrate analogs. However, the measure of their effective activity in situ (i.e., in living cells) is necessary to understand the normal intracellular sphingolipid turnover. Moreover, their determination in cells from patients with genetic enzyme deficiencies represents a key parameter of the pathophysiology of sphingolipid storage disorders. In this report, we have developed a procedure for estimating the effective activity of lysosomal sphingomyelinase and ceramidase in situ. This procedure is based on the selective targeting to lysosomes of a natural substrate under physiological conditions of substrate influx. Epstein-Barr virus-transformed human lymphoid cells and human skin fibroblasts were incubated with purified human low density lipoproteins (LDL) containing [3H]ceramide-labeled sphingomyelin. Data demonstrate that this substrate is internalized through the apolipoprotein B/E receptor pathway and targeted to lysosomes. Lysosomal localization of the incorporated substrate was evidenced by ultrastructural autoradiography and subcellular fractionation as well as by metabolic studies in mutant cells. Short-term pulse-chase experiments with LDL-associated [3H]ceramide-labeled sphingomyelin allowed us to determine the effective activity of lysosomal sphingomyelinase and ceramidase in normal cells. Initial velocities of sphingomyelin and ceramide degradation were, respectively, estimated at 0.66 and 1.14 nmol.h-1.mg cell protein-1 in lymphoid cells, and 5.4 and 3 nmol.h-1.mg cell protein-1 in skin fibroblasts. The advantages and applications of these in situ studies are discussed.

Mixed desmoplastic primitive neuroepithelial tumor of infancy: a light microscopic, immunocytochemical, ultrastructural and genetic study.
We describe a case of a desmoplastic brain tumor which was initially resected from the right fronto-temporal region in a 2 year-old boy. This nodular, calcified tumor was vascularized by the internal carotid artery and the middle meningeal artery branches. Grossly, it contained several mucoid cysts. Light microscopy showed cords or nests of small cuboidal cells surrounded by a loose connective tissue and desmoplastic areas containing fibers and spindle cells. The cuboidal cells expressed epithelial, neuronal and neuroendocrine markers. Some foci of spindle cells showed glial differentiation. The tumor recurred 16 months later and displayed some characteristics of the small cell neuroepithelial component, mitoses being conspicuous. Electron microscopy revealed undifferentiated clear cells, some containing neurosecretory granules. Karyotyping demonstrated the following formula: < 15 > 46, t(8;11) (q13; q11). The chromosome 11 breakpoint was different from that described in Ewing's sarcoma. This isolated translocation has not been previously reported to our knowledge. These unusual features lead us to report this case and to discuss its pathogenesis.

Human beta-mannosidase deficiency associated with peripheral neuropathy.
Human beta-mannosidosis is an inherited lysosomal storage disorder described in only seven families. We present a further case in a black African 14-year-old boy with severely deficient beta-mannosidase activity, bilateral thenar and hypothenar amyotrophy, electrophysiologically demonstrable demyelinating peripheral neuropathy, and cytoplasmic vacuolation of skin fibroblasts and lymphoid cells. The clinical and biochemical features of our patient are compared to those of previously reported patients.

Accurate differentiation of neuronopathic and nonneuronopathic forms of Niemann-Pick disease by evaluation of the effective residual lysosomal sphingomyelinase activity in intact cells.
Niemann-Pick disease types A and B are two clinical forms of an inherited lysosomal storage disorder characterized by accumulation of sphingomyelin due to deficient activity of the lysosomal enzyme, acid sphingomyelinase. Patients with both types have hepatosplenomegaly, but only those with type A have nervous system involvement leading to death in early infancy. The residual activities of lysosomal sphingomyelinase in types A and B have never been well characterized because of limitations in both in vitro enzymatic assays and loading tests on intact cells. To evaluate the effective level of sphingomyelinase activity, intact, living cultured Epstein-Barr virus-transformed lymphoid cells were incubated with a radiolabeled sphingomyelin that was first associated to human low-density lipoproteins. This lipoprotein-associated sphingomyelin was targeted to lysosomes, thereby permitting selective hydrolysis by the lysosomal sphingomyelinase. Short-term pulse-chase experiments allowed the determination of the initial rates of degradation; in normal cells, the half-time of sphingomyelin degradation averaged 4.5 h. Whereas cells from the severe neuronopathic type A form of Niemann-Pick disease exhibited about 0.15% residual sphingomyelinase activity, cells from patients with the visceral type B form exhibited about 4%, i.e., 27 times more. Cells from heterozygous Niemann-Pick subjects showed about 70% residual activity. These results provide the first approach to measuring the effective activity of a lysosomal enzyme and represent an accurate method for the differential diagnosis of Niemann-Pick disease types A and B. They also support the hypothesis of relationships among the effective in situ residual enzyme activity, the amount of stored substrate, and the severity of the ensuing lysosomal storage disorder.

Reappraisal of Rasmussen's syndrome with special emphasis on treatment with high doses of steroids.
Eight patients with Rasmussen's syndrome and epilepsia partialis continua were treated with high doses of steroids, including pulses of methylprednisolone and prednisone in decreasing doses. Three patients exhibited clinical, radiological, or histological evidence of bilateral involvement. Epilepsy and focal deficit decreased within six months in seven patients. Only five patients, in whom steroid treatment had begun less than 15 months after the onset of epilepsia partialis continua, experienced a lasting effect although they had periodic episodes of transient relapse. Treatment with high doses of steroids seems advisable during the first year after onset of epilepsia partialis continua, before hemiplegia has developed and in cases with bilateral involvement.

[Cerebral arteritis, carotid thrombosis and rubella: relation or coincidence?].
A 10 year-old boy presented with an acute transitory right hemiparesis with aphasia. On CT-scan there was a left temporal low density. The cerebral angiography showed a total obstruction of the left terminal internal carotid with a "beading" of the posterior cerebral artery on the same side. Blood serologies and the presence of specific IgM in the cerebrospinal fluid gave evidence for recent rubella. An other arteriogram after a follow-up of 3 months showed a persistent obstruction of the internal carotid but a disappearance of the cerebral posterior artery abnormalities.
