Hereditary motor and sensory neuropathy with deafness, mental retardation and absence of large myelinated fibers.

Two brothers with a presumably hereditary motor and sensory polyneuropathy (HMSN), sensory-neural hearing loss and mental retardation had clinical features and neuropathological changes in the sural nerve which may set the disorder apart from previously described types of HMSN. Consecutive sural nerve biopsies from one case showed absence of large myelinated fibers and a normal complement of small fibers. We infer from our findings that a developmental abnormality with faulty growth and subsequent axonal atrophy may be responsible.

Rapid diazepam introduction (venous or rectal) in childhood epilepsy: taxonomic and therapeutic considerations.

Rapid diazepam (DZP) introduction was investigated in 24 children with different types of cryptogenic or symptomatic generalized epilepsy and EEG epileptic "status" with EEG and pharmacologic monitoring. In 12 cases DZP was given intravenously and in another 12 by the rectal route. In general, intravenous administration proved more rapid and more effective as to high blood levels of DZP and the arrest of the paroxysmal activity. However, when the results were correlated to the different forms of paroxysmal EEG activity it was apparent that cases with a typical hypsarrhythmic EEG pattern under the age of 12 months and cases with unorganized paroxysmal activity over the age of 12 months are insensitive or only slightly sensitive to both intravenous and rectal introduction. A number of taxonomic and therapeutic considerations are presented.

[The Guillain-Barré syndrome. The clinico-electrophysiological correlations].

The authors refer about clinico-electrophysiological correlations in children with Guillain-Barré syndrome (GBS). The dates confirm the diagnostic and prognostic value of electrodiagnostic studies in GBS, so that the authors suggest an electrodiagnostic protocol. According to the authors, independently of the extent of electrophysiological abnormalities, young age has a favourable influence on the restoration of conduction abnormalities and on the evolution of damage to peripheral neurones.

Secondary generalized epilepsy in childhood: EEG patterns and correlation with responsiveness to benzodiazepines or ACTH (preliminary note).

Secondary generalized epilepsy in childhood, characterized by absences or minor motor seizures, occurs in the forms of various syndromes, as defined by current classifications. EEG often shows continuous or subcontinuous paroxysmal activity associated with partly reversible psychomotor or mental regression. The paroxysmal activity can exhibit one of two distinct patterns: "organized" or "disorganized," although intermediate forms are common. The two patterns differ not only morphologically but also in the responsiveness to drug or hormone therapy, reactivity to stimuli, sleep changes and frequency of disordered slow rhythms. These features are illustrated by means of a survey of 10 cases.

[Leukoencephalopathy with swelling, megalencephalopathy and surprisingly mild course. A case report].

Leukoencephalopathy with swelling and a discrepantly mild clinical course is a recently identified syndrome described by van der Knaap et al. It is characterised by macrocephaly occurring during the first year of life, initially normal or nearly normal development, slowly progressive ataxia and spasticity with initial preservation of intellectual functions. MRI shows diffuse abnormality of signal intensity in the hemisphere white matter with subcortical cyst-like spaces in the fronto-parietal and anterior temporal areas. The case of a 5-year-old boy whose clinical and neuroimaging findings are consistent with this syndrome is reported. The clinical and neuroimaging findings of this case may provide further information about this new syndrome which could possibly be useful also for genetic counselling.

[Early autism and congenital muscular dystrophy: a clinical case].

The authors describe the case of a twelve-year-old patient presenting early autism associated with congenital muscular dystrophy--subtype IV, according to the subclassification of Fukuyama (slight mental retardation, ability to walk, muscle pseudohypertrophy). To our knowledge, this association has never been reported. Several factors may have played a causative role in the development of an autistic disorder in the patient. The authors suggest the following as the most significant ones: disharmonious personality, weak emotional structure, inadequate primary relation with the mother, poor environmental influences, frustrations encountered because of the muscular disorder.

[Neurogenic hypernatremia syndrome in children].

Chronic "neurogenic" hypernatremia is the consequence of defective thirst mechanism either alone or in combination with impaired osmoregulation of ADH release. Both the specific receptors and the structures involved in hormonal secretion are localised in the hypothalamic area. "Neurogenic" hypernatremia can be secondary to a hypothalamic lesion of different type (neoplastic, vascular, malformative) or rarely it can be idiopathic. We present three cases: two females 4 and 5 months old, affected by cerebral malformations involving midline structures of the brain (III ventricule, corpus callosum etc.) and a male 4 years old with a idiopathic form. We discuss the relationship between the origin of the cerebral malformations and the ontogeny of the structures involved in the control of the osmolarity. Moreover we have observed that the hypernatremia in associated with hyperlipemia: the pathogenetic hypothesis explaining this abnormality are discussed.
