RESUMO
PURPOSE: To describe the management of infants with epileptic spasms (ESs) in a low-income country and identify factors predictive of their prognosis. MATERIAL AND METHODS: We conducted a retrospective study in a university hospital in Tunis, Tunisia, over a period of 10 years. We included infants with recurrent ESs. RESULTS: Thirty-eight patients were included. The median age at onset of ESs was 5 months. Typical hypsarrhythmia was found in 21 patients (55%). Brain MRI was done in 32 patients (84%) and metabolic work-up in 34 patients (89%). ESs were categorized as symptomatic in 58% of the patients. Vigabatrin was prescribed as the first-line drug in almost half of the patients. At the last follow-up, 63% of the patients were seizure-free and 82% had a psychomotor delay. The presence of other types of seizures was associated with uncontrolled epilepsy at the last follow-up (P=0.020). The persistence of spasms after the first-line treatment was associated with abnormal final psychomotor development (P=0.047). CONCLUSIONS: Investigation practices and final outcomes of our patients were comparable to data from high-income countries. Treatment practices have been standardized to be in line with international guidelines.

Rosai-Dorfman disease (RDD) is a benign lymphoproliferative disorder characterized by cervical lymph node enlargement with a consistent risk of airway compression and esthetic damage. Extranodal localizations are also described. There is no therapeutic consensus for pediatric forms of RDD. Through 2 pediatric cases with nodal involvement in 1 patient and a sinonasal and soft tissue localization in the other, we focus on the management problems of both nodal and extranodal RDD.

The natural history and clinical presentation of the perinatal-lethal Gaucher's disease, a severe variant of acute type 2 Gaucher's disease, is quite different from classic type 2 Gaucher's disease. Rare reported patients had an overlapping phenotype between these two forms confirming that phenotyping may be difficult. Here we report three patients with an intermediate phenotype. The first two patients showed at birth cholestatic jaundice, hepatosplenomegaly and hematological involvement consistent with hemophagocytosis in one patient, the death occurred from a severe liver involvement in one and lung disease in the second in the absence of neurological symptoms. The third patient displayed ichthyosis and facial dysmorphism but with neurological degeneration course and survival consistent with classic type 2 Gaucher's disease.

Congenital generalized lipodystrophy (CGL) is a rare disorder characterized by near complete absence of adipose tissue from birth. At least 2 genes located in 9q34 (AGPAT2) and 11q13 (Seipin) are implicated in type 1 and 2, respectively, and result in insulin resistance. We report here a novel case of CGL type 1 resulting from a novel homozygote mutation in the AGPAT2 gene. The clinical picture included pseudoathletic muscular hypertrophy, hypertrophic cardiomyopathy, enlarged liver, hypermetabolism rate, and hyperinsulinemia in a 1-year-old child from Libya. Peripheral hypertonia and reflex excitability revealed signal abnormalities in white matter on magnetic resonance imagery, which has not been described previously in the literature.

OBJECTIVE: Analysis of epidemiological data concerning GSD I in Tunisia. SUBJECTS AND METHODS: All the cases diagnosed as GSD I between 1992 and 2005 in a paediatric department recruiting all the metabolic diseases referred from the North of Tunisia were reviewed. Individual data (sex, socioeconomic and educational background, geographic origins, insurance coverage) were collected and pedigrees were reconstituted. RESULTS: Twenty-two cases (9 boys and 13 girls from 20 homes) were identified. Fourteen belonged to 11 families originating from the North of Tunisia; ten of them are still alive. Both parents in 4 homes (21%) and one parent in 9 homes (47%) were illiterate. Most of the homes (60%) had a low income and 45% comprised at least 3 children. Only 7 homes (35%) had health insurance. Pedigrees indicated 44 infant deaths and at least 10 other cases fulfilling the clinical features of GSD I but not diagnosed. CONCLUSION: The paediatric prevalence of GSD I in the North of Tunisia can be estimated to 7.93 cases per one million inhabitants and its incidence to 1/100,000 births. However, it is likely to be more frequent because of underreporting or underdiagnosis leading to precocious deaths.

Glycogen storage disease type Ia (GSD Ia; OMIM 232200) is an autosomal recessive disorder of glycogen metabolism caused by a deficiency of the microsomal glucose-6-phosphatase (G6Pase). It is characterized by short stature, hepatomegaly, hypoglycaemia, hyperuricaemia, and lactic acidaemia. Various mutations have been reported in the G6Pase gene (G6PC). In order to determine the mutation spectrum in Tunisia, we performed mutation analysis in 22 Tunisian type I glycogen storage disease (GSD I) patients belonging to 18 unrelated families. All patients were clinically classified as GSD Ia. The R83C mutation was found to be the major cause of GSD Ia, accounting for 24 of 36 mutant alleles (66.6%), The R170Q mutation was the second most frequent mutation; it accounts for 10 of 36 mutant alleles (27.7%). The R83C and R170Q mutations could be rapidly detected by PCR/RFLP. Since the majority of Tunisian patients carried R83C and/or R170Q mutations, we propose direct screening of these mutations as a rapid, valuable and noninvasive tool for diagnosis of GSD Ia in Tunisian as well as in Northern African populations.
