title: [Guillain-Barre syndrome. Experience in a third level hospital].
abstract: BACKGROUND
  Acute peripheral neuropathy represents a medical emergency. The causes of it are diverse and plentiful. The most common cause of acute paralytic peripheral neuropathy is the Guillain-Barré syndrome (GBS). As many as 85% of those affected can be expected to make an excellent recovery.
  
  
  OBJECTIVE
  To describe the principal risk factors associated, clinical manifestations, treatment, evolution and complications of 28 cases of Guillain-Barré syndrome (GBS) in the "Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán".
  
  
  METHODS
  We search in our computer records all files under diagnostic of GBS, during the last ten years. We found 28 cases that were available to study.
  
  
  RESULTS
  Mean age was 37 years old (SD 17.2). Fifteen patients were female (54%) and 13 were male (46%). Nine patients (32%) were preceded by a superior via infection, 5 (18%) by a diarrhea illness and 14 patients had not a predisposing factor. The duration of symptoms before diagnostic has a median of 7 days (2-15). Twenty-six patients (93%) had an ascending paralysis and 18 had paresthesias (64%). The most frequent subtype was acute inflammatory-demyelinating polyneuropathy (AIDP) in 18 patients (64%), acute motor-sensory axonal neuropathy (AMSAN) in 5 (18%), acute motor axonal neuropathy (AMAN) in 3 (11%) and 2 patients (7%) had the Fisher-Miller syndrome. Fifteen patients (54%) developed respiratory involvement requiring mechanical ventilation. Twenty-four patients (86%) had cerebrospinal fluid proteins elevated. Twenty patients (72%) had a total recovery, 6 (21%) had a partial recovery and 2 had not any response (7%).
  
  
  CONCLUSIONS
  GBS is a particularly highstakes illness in that its onset is sudden and paralysis is frequently extreme (requiring assisted respiration), however, as many as 85% of those affected can be expected to make an excellent recovery. In our study the majority of patients (54%) develop respiratory involvement requiring mechanical ventilation but in this group the majority had a favorable outcome (71%).
