    Il capitolo fornisce gli elementi base dell'elettroneurografia (ENG), dell'elettromiografia (EMG) e della stimolazione muscolare diretta. Nell'ambito dell'ENG descrive i metodi per la valutazione della velocità di conduzione motoria (VCM) e sensitiva e dei potenziali d'azione muscolare composto e sensitivo, della risposta F, del riflesso H e della stimolazione ripetitiva. Nell'ambito dell'EMG descrive i principali quadri della registrazione elettromiografica, inclusi l'attività spontanea, il potenziale di unità motoria e la contrazione volontaria. Infine nell 'ambito della stimolazione muscolare diretta descrive il razionale, la tecnica e i criteri per la diagnosi differenziale tra neuropatia e miopatia

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Acute neuromuscular respiratory failure after ICU discharge. Report of five patients

    Objective: To describe a syndrome of acute neuromuscular respiratory failure (NM-ARF) caused by ICU-acquired acute myopathy and neuropathy. Design: Case series. Setting: General Regional University Hospital in Brescia, Italy. Patients: Five adult patients with NM-ARF after prolonged ICU stay and successful weaning from the ventilator and ICU discharge. Interventions: None. Measurements: Clinical signs of NM-ARF electroneurography and electromyography (ENMG) of peripheral nerves and muscles, and functional assessment of respiratory muscles. Results: NM-ARF was diagnosed at the time of (one case), or 1-3 days after, ICU discharge. Limb weakness alarmed the physicians, while the signs of the NM-ARF were initially undetected. In the first observed case the acute respiratory failure was near fatal, and necessitated ICU readmission, while in the other cases 2 weeks of aggressive chest physiotherapy permitted resolution of the respiratory failure
