    Notes: Summary A multicentre retrospective study was carried out on the characteristics and course of myasthenia gravis (MG) in Italy. Data from 1152 patients, fairly representative of the myasthenic population seeking medical advice, were analysed for diagnostic criteria, clinical aspects and therapeutic approaches. Mean follow-up was 4.9 years. The disease was correctly diagnosed within 2 years of the onset in 80% of cases. Onset of symptoms peaked in the second and third decade in females and fell between 20 and 59 years in males. At first observation 87% of the patients had generalized MG. Maximal worsening was observed within 3 years in 77% of patients. At the last follow-up, 35% of cases were symptom-free (pharmacological remission 24%, remission without treatment 11%). The more severe the disease at the first observation and at the maximal worsening of symptoms, the lower was the proportion of remissions. Steroids were given in 54% and immunosuppressants in 18%. Thymectomy was performed in 72%, mostly in women, younger than age 40, and with generalized MG. Thymectomy seemed to improve the course of the disease, mostly in patients operated on shortly after diagnosis and those with generalized mild-to-moderate disease and with a normally involuted thymus. MG was lethal in 4% of patients, principally men, older than 40, in grade 3 or worse at first observation, with a short history of disease, and with thymona.

    Notes: Summary Azathioprine (Aza) has been used alone or in combination with steroids for two groups of myasthenic patients. Positive responses were noted in 75% of patients on Aza alone and in 70% receiving the combined regimen. The clinical course of the two groups differed in terms of respiratory crisis and need for plasma exchange. With an appropriate Aza administration schedule side-effects were not a limiting factor to its use. Aza treatment induced a reduction in anti-AchR-antibody level that was correlated with clinical improvement and greatly decreased the need for steroids.

    Description / Table of Contents: Sommario Abbiamo paragonato 25 pazienti affetti da neuropatia ereditaria sensitivo-motoria (HMSN) di tipo I ad ereditarietà autosomica dominante con 7 pazienti affetti da neuropatia ipertrofica ad ereditarietà non dominante. Tutti i pazienti con ereditarietà autosomica dominante sono risultati portatori della duplicazione 17p11.2, dimostrando così che questa è largamente presente nelle famiglie HMSN I. Il secondo gruppo comprendeva: due fratelli affetti da una neuropatia ipertrofica di gravità nettamente diversa, nati da genitori sani non consanguinei; due sorelle con un fenotipo HMSN I nate da genitori sani, cugini di primo grado; due fratelli con un fenotipo HMSN III nati da genitori non consanguinei affetti da HMSN II; un bimbo con un classico fenotipo HMSN III, nato da genitori sani, non consanguinei. L'analisi del DNA ha dimostrato l'assenza della duplicazione sia nei pazienti del secondo gruppo che nei loro genitori. I nostri dati dimostrano che: l'HMSN III è eterogenea e comprende pazienti omozigoti per differenti geni neuropatogeni; è opportuno tenere distinti i pazienti con neuropatia ipertrofica recessiva da quelli portatori di una HMSN Ia dominante poiché è probabile che le due malattie siano dovute a difetti genici diversi.
    Notes: Abstract We compared 25 autosomal dominant hereditary motor and sensory neuropathy (HMSN) type I patients with 7 subjects affected by hypertrophic HMSN with non-dominant inheritance. All the autosomal dominant HMSN I cases carried the chromosome 17p11.2 duplication, providing evidence that it is widely represented in HMSN I families. The second group included: Two siblings born to unrelated, unaffected parents and suffering from hypertrophic HMSN of strikingly different severity; two sisters with HMSN I phenotype, born to first-cousin unaffected parents; two brothers with HMSN III phenotype born to unrelated parents both showing HMSN II phenotype; a child with classic HMSN III phenotype, born to unrelated, unaffected parents. The 17p11.2 duplication was not found in any of the patients of the second series or in their parents. Our data provide further evidence that: HMSN III is heterogeneous and encompasses the homozygous expressions of different neuropathic genes; it is advisable to separate autosomal recessive hypertrophic HMSN from dominant HMSN Ia, because they appear to be due to different DNA mutations.

    Description / Table of Contents: Sommario 227 sieri da pazienti miastenici sono stati titolati per la presenza di anticorpi specifici anti recettore colinergico. Il dosaggio è stato eseguito con recettore estratto da muscolo di feto bovino. 73.5% dei casi sono risultati positivi per la presenza di questi anticorpi. È stato possibile evidenziare correlazioni con aspetti clinici come: lo stadio clinico, la durata della malattia ed, inoltre, titoli più elevati sono stati riscontrati nei pazienti in cui la malattia è insorta prima dei 40 anni.
    Notes: Abstract 227 sera from myasthenic patients were tested for the presence of anti-AChR antibodies (anti-AChR Abs) by mean of a fetal calf receptor (Fc-AChR); 73.5% of cases proved positive with this method. Significant correlations were found between presence of anti-Fc-AChr Abs and various clinical aspects such as: clinical stage and duration of disease; moreover significantly higher than the median titers were found among younger patients (i.e. age 〈40 yrs).
