Background: Guillain-Barre Syndrome (GBS) is an acute polyradidulonevritis which is primitive inflammatory and demyelinisant. It represents the most frequent cause of acute peripheric paralysis of the child., Aim: To study the epidemiologic, clinic, electromyographic, outcome and therapeutic features of this disease., Methods: 22 cases of GBS were reported in the pediatric department of Ibn El Jazzar's hospital of Kairouan from January 1990 to September 2009., Results: The GBS represents a hospital frequency of 0.45 %o . The mean age of the patients was 6.88 years with a sex ratio of 1.2. The prodromic infectious manifestations were observed in 54.5% of cases. The clinic symptomatology was the muscular deficiency observed in all cases with absence of deep reflex an albumincytologic dissociation was observed in 12 cases. The electromyographic manifestations were: an axonal disorder in four cases, axonomyelinic in eight cases and myelinic in seven cases. A specific therapy by intravenous polyvalent immunoglobulin was prescribed for 14 patients. The evolution was favourable in 10 cases with total recovery three cases of drop foot gait were observed, seven patients were lost to follow up and two patients are dead., Conclusion: GB syndrome is the most frequent cause of child acute primitive distal paralysis, since acute polio has been eradicated. Acute Respiratory disorder is the most severe complication this syndrome can lead to in 5% of cases. The course of the disease is often mild and severe scars are only encountered in 5 to 10 % of cases. Indeed, the use intravenous immunoglobulin has utterly changed prognosis.

A retrospective study of 120 cases of acute polyradiculoneuropathy hospitalized in the National Institute of Neurology, since 1974. We analysed the clinical and neurophysiological pictures, the course of the disease and the prognosis. All ages and sex were affected. The mean age of onset was 34 years. There were a predominance of male 2.5:1. Weakness, particularly of the lower limbs, was the initial complaint of patients. A rise in the level of cerebro-spinal fluid protein in the absence of pleiocytosis was found in 80% of patients. Electrophysiological data showed most frequent sensory motor demyelinating polyradiculo-neuropathies (60%). Conduction blocks were found in 90% of cases. The last 6 years, gammaglobulin (0.4g/kg per day for 5 days) was given for the first days of the disease and has been shown to improve the vital and functional prognosis.
