    Notes: Abstract We evaluated outcome and the clinical value of cognitive impairment in systemic lupus erythematosus (SLE). Fifty-one consecutive SLE subjects with or without overt nervous system involvement received two comprehensive neuropsychiatric and neuropsychological assessments, including the Mental Deterioration Battery, the Mini Mental State Examination (MMSE), and tests from the Wechsler Adult Intelligence Scale. The two neuropsychological assessments were made when subjects were in stable neurological condition. Twenty-seven patients were found to have neuropsychiatric symptoms (NP-SLE) at the first assessment, and three others developed them during the follow-up. Fifteen patients (10 NP-SLE) had cognitive impairment at the first assessment. At retest the cognitive deficit persisted in all patients but one (non-NP-SLE) and had developed in four others. In the cognitively impaired subjects scores on MMSE approached the cutoff for an overt dementing condition. No progressively decreasing scores were found on any of the tests. No relationships were shown between neuropsychological diagnosis and neuropsychiatric disorder, neuroradiological findings, disease activity, or steroid and nonsteroid immunosuppressive therapy. Cognitive impairment thus seems to be a stable symptom of CNS involvement in SLE. It corresponds to the subjective complaint of intellectual difficulties and marginal performance on the MMSE. Intellectual deterioration may occur in patients without other symptoms of NP-SLE. Standardized neuropsychological testing methods should be used routinely to assess SLE patients.

    Description / Table of Contents: Sommario Le Polineuropatie Amiloidosiche Familiari (FAP) sono un gruppo eterogeneo di affezioni trasmesse in via autosomica dominante caratterizzate dalla deposizione sistemica di fibrille amiloidi e dall'interessamento preminente del Sistema Nervoso Periferico (SNP). Queste affezioni, descritte frequentemente in vari gruppi etnici, sono state raramente segnalate in Italia. L'osservazione di un 42enne, venuto alla nostra osservazione per una perdita della sensibilità termo-dolorifica agli arti inferiori, ci ha consentito l'identificazione di una estesa famiglia italiana con 19 membri affetti da FAP. La diagnosi era basata su dati clinico-strumentali in 8 soggetti e su notizie anacatamnestiche in altri 11. Nella famiglia da noi studiata la malattia esordisce tra i 35 e i 50 anni di età e il decorso è progressivo e spesso fatale. L'esordio è contrassegnato dai sintomi disautonomici e neuropatici. La compromissione cardiaca e renale è frequente ed è spesso causa di morte.
    Notes: Abstract Familial amyloidotic polyneuropathy (FAP) is a heterogeneous group of genetic disorders characterized by progressive systemic deposition of extracellular amyloid fibrils, mainly affecting the peripheral nervous system (PNS). These disorders, inherited as an autosomal dominant trait, have frequently been described in various ethnic groups, but have rarely been reported in Italy. A 42 year-old man came to our observation for loss of pain and temperature sense in his legs. Clinical and laboratory data pointed to an amyloidotic polyneuropathy. This led us to discover a large italian kindred in which 19 members were affected by FAP. The diagnosis, established in 8 members on the clinical and laboratory findings, was ana-catamnestic in other 11. In this kindred the onset of the disease ranges from 35 to 50 years of age and the course is progressive and often fatal. The early symptoms are mainly related to autonomic disturbances and to peripheral neuropathy. Cardiac and renal involvement occurs frequently and may be life-threatening.

    Notes: Abstract We report a 26-year-old Italian man with X-linked Charcot-Marie-Tooth (CMT) disease type 1 (CMT-X1) and a negative family history for neuromuscular diseases. Clinical and electrophysiological examinations of the patient's mother and siblings were normal. Molecular analysis by polymerase chain reaction – single-strand conformation polymorphism (PCR-SSCP) on genomic DNA from the patient and all members of his family revealed a C-to-T transition in codon 8 of exon 2 of the connexin-32 (Cx32) gene on the X chromosome only in the patient. This transition in the 5'-coding region, resulting in a Thr-Ile substitution, is likely to be the cause of CMT phenotype in our patient, and it represents a new de novo mutation of the Cx32 gene.
