RESUMO

OBJECTIVE: To report clinical, neuroradiologic, neurophysiologic, and genetic findings on 16 patients from 11 unrelated families with a remarkable uniform phenotype characterized by infantile ascending hereditary spastic paralysis (IAHSP). METHODS: Sixteen patients from 11 families, originating from North Africa and Europe, who presented severe spastic paralysis and ascending progression were studied. RESULTS: Spastic paraplegia started in the first 2 years of life in most patients and extended to the upper limbs by the end of the first decade. The disease progressed to tetraplegia, anarthria, dysphagia, and slow eye movements in the second decade. The clinical course showed a long survival and preservation of intellectual skills. Clinical, neuroradiologic, and neurophysiologic findings were consistent with a relatively selective early involvement of the corticospinal and corticobulbar pathways. No signs of lower motor neuron involvement were observed, whereas motor evoked potentials demonstrated predominant involvement of the upper motor neurons. MRI was normal in young patients but showed brain cortical atrophy in the oldest, predominant in the motor areas, and T2-weighted bilateral hyperintense signals in the posterior arm of the internal capsule. The ALS2 gene, recently found mutated in consanguineous Arabic families with either an ALS2 phenotype or a juvenile-onset primary lateral sclerosis, was analyzed. Alsin mutations were found in only 4 of the 10 families, whereas haplotype analysis excluded the ALS2 locus in one family. CONCLUSIONS: The syndrome of IAHSP is genetically heterogeneous, and no clinical sign can help to distinguish patients with and without Alsin mutations.

RESUMO

Seckel syndrome is a rare autosomal recessive condition belonging to the group of osteodysplastic primordial "dwarfism" and characterized by the association of 1) severe pre- and postnatal growth retardation, 2) microcephaly with mental retardation, and 3) specific dysmorphic features. Recently, two disease loci have been mapped to chromosomes 3q22.1-q24 and 18p11.31-q11.2, respectively, by homozygosity mapping in consanguineous families. Here, we report on the exclusion of these loci in five consanguineous and one multiplex nonconsanguineous Seckel syndrome families and in two consanguineous families presenting type II osteodysplastic primordial dwarfism. These results support the view that Seckel syndrome is a clinically and genetically heterogeneous condition.

RESUMO

We report on two new cases of syndromic lissencephaly in two consanguineous sibs, with skeletal abnormality, born to young, healthy, second cousin parents with healthy children. In Case 1, fetal ultrasound screening at 32 weeks of gestation showed microcephaly, skin infiltration and equinovarus feet. MRI disclosed cerebral agyria, hypoplastic cerebral mantle and posterior agenesis of the corpus callosum. The propositus, a boy, died soon after birth at term. In Case 2, fetal ultrasound study performed at 16 weeks of gestation disclosed skin infiltration. MRI at 22 weeks of gestation showed microcephaly with agenesis of corpus callosum and cerebellar hypoplasia. Pregnancy was terminated at 22 weeks of gestation. The fetus had normal 46, XY karyotype and similar anomalies found in the index case, with cranio-facial edema and arthrogryposis. X-ray films showed epiphyseal stippling of cervical vertebrae, feet and sacrum. Metacarpal bones were shortened with hypoplastic distal phalanges. Neuropathological findings were concordant with the pattern described in type III lissencephaly: an agyric brain with hypoplastic brain stem and cerebellum, severe neuronal loss of the cortical plate, matrix zone, basal ganglia, brainstem nuclei and spinal cord with axonal swelling and microcalcification. This entity seems to be a new syndromic lissencephaly type III, because of epiphyseal calcifications and metacarpophalangeal bone dysplasia.

RESUMO

DECLINING INCIDENCE: Between 1982 and 1994, the incidence of rubella infections during pregnancy in France declined form 45 to 9 cases per 100,000 births. The incidence of congenital rubella declined from 5 to 0.85 per 100,000 births. These results are the fruit of systematic vaccination of 1-year-old children in France. Eradication of congenital rubella has been achieved in Sweden and requires further efforts to be obtained in our country. SEROLOGY: Physicians must systematically check rubella serologies in all women desiring pregnancy and/or of reproductive age even if they have been vaccinated. Rubella serology must be checked in all pregnant women even if they were seropositive during a prior pregnancy. IN CASE OF EXPOSURE OR ERUPTION DURING PREGNANCY: Serology must be obtained as early as possible in case of suspected rubella infection during pregnancy with a second serology 3 weeks later. The IgM titre should be obtained in case of suspected exposure with significant rise in IgG in successive serologies, if specific IgG titre is elevated after an eruption, if the first serum sample was taken late after suspected exposure, and finally if a systematic serology early in pregnancy is positive after a previously negative serology. ANTENATAL DIAGNOSIS: PCR on amniotic fluid or fetal blood is indicated if a seroversion occurs before 18 weeks gestation. Therapeutic termination of pregnancy should be proposed if fetal infection is certain. After 18 weeks, there is nearly no risk for the fetus: an antenatal diagnostic sample is not required and ultrasound surveillance is sufficient.

RESUMO

Between 1978 and 1987, 109 patients without metastatic disease were treated by induction chemotherapy for inflammatory breast cancer (IBC) or "neglected" locally advanced breast cancer (LABC): 62 patients had a clinical history of rapidly growing tumours (doubling time < or = 4 months) and inflammatory signs; conversely, the 47 neglected patients had local inflammation with a longer history of LABC. 103 patients were fully evaluable. All patients received the same induction chemotherapy with doxorubicin, vincristine, cyclophosphamide and 5-fluorouracil. After six cycles, locoregional treatment was by radiotherapy if a complete or nearly complete response had been obtained, and total mastectomy, with pre or postoperative radiotherapy, in other cases. The chemotherapy after local treatment comprised of six cycles for LABC and 12 cycles for IBC (six without doxorubicin). With a median follow-up of 120 months, the median overall survival (OS) time was 70 months as against 45 months for disease-free survival (DFS). No difference was observed for OS and DFS between LABC and IBC. The regional recurrence rate was 24% (15% for radiotherapy alone). 20 factors of potential prognostic significance were evaluated by univariate and multivariate analysis. For DFS and OS, univariate analysis suggested a worse prognostic significance for "peau d'orange" appearance of the skin, clinical evidence of node involvement and poor response to chemotherapy after three cycles, on mammographic criteria. The cumulative dose of doxorubicin after three cycles seemed to have a significant effect on OS (P < 0.03) but was too closely correlated with age to draw definite conclusions. In the multivariate analysis, "peau d'orange", menopausal status and clinical node involvement predicted DFS. "Peau d'orange" and clinical node involvement also predicted OS. Our results indicate that IBC and LABC do not behave differently when treated with our procedure.
