Scurvy still exists in children: A case report.

Scurvy is one of the oldest diseases known to mankind. Although rare lately, the clinical suspicion arises in front of a precarious situation or deficient nutrition and food restriction secondary to a psychiatric condition, even in patients with non-specific complaints. We report the observation of a 6 -year- old boy, followed for autism since the age of 3 years and who was admitted for limping, hemorrhagic syndrome, arthritis and weakness. The diagnosis of child abuse was initially suspected but clinical and radiological abnormalities seen were characteristic of scurvy. Vitamin C level was undetectable. The child had an unbalanced diet.A favorable outcome was rapidly obtained following supplementation. Scurvy is rare, but it should be mentioned among children with psychiatric disorders, presenting with musculoskeletal manifestations or hemorrhagic syndrome. It is essential to prevent it by systematic dietary supplementation of vitamin C in children with eating difficulties.

Pediatric Noncerebral Thromboembolism: Etiological Assessment and Outcome.

OBJECTIVE: To report clinical presentation and etiologic investigation findings during pediatric noncerebral thromboembolism. METHODS: Retrospective study of cases of vascular non cerebral thromboses admitted in Medicine infantile A Department of the Children's Hospital of Tunis over 08 years. RESULTS: We confirmed 14 cases of non cerebral vascular thromboses. So that these accidents constitute 0,26 ‰ of the overall etiologies of hospitalizations in the Department. The mean age of our patients was 56±41 months [25 days-12 1/2 years]. The sex ratio was 1.8. The vascular incident was venous in 2/3 of cases. The clinical presentation was mainly painful swelling in four cases, abrupt dyspnea and hematemesis in three cases each and the incident was locally asymptomatic in four cases. Thromboses locations included deep vein thrombosis of limbs (n=6), vena cava thrombosis (n=1), portal thrombosis (n=4) and pulmonary embolism (n=3). The promoting factors identified were: tumors in seven cases, thrombophilias and catheterization in four cases each, trauma, surgery and Behçet disease in one case each. Eleven patients received anticoagulant treatment including unfractioned heparin in three cases and low molecular weight heparin in the other cases. No one died while four patients developed sequelae. CONCLUSION: Vascular thromboses are rare in children. They are mostly venous and diagnosed in ill children especially those having central venous catheters. Outcome of pediatric thromboembolism depends on efficient anticoagulation therapy which is well tolerated by children.

Congenital pulmonary alveolar proteinosis.

Pulmonary alveolar proteinosis (PAP) is a rare syndrome characterized by pulmonary surfactant accumulation within the alveolar spaces. It occurs with a reported prevalence of 0.1 per 100,000 individuals. Two clinically different pediatric types have been defined as congenital PAP which is fatal and a late-onset PAP which is similar to the adult form and less severe. The clinical course of PAP is variable, ranging from spontaneous remission to respiratory failure. Whole-lung lavage is the current standard treatment for PAP patients. We report a new congenital case of PAP.

Brain MRI and biological diagnosis in five Tunisians MLD patients.

Metachromatic leukodystrophy (MLD) is a recessive autosomal disease which is characterized by an accumulation of sulfatides in the central and peripheral nervous system. It is due to the enzyme deficiency of the sulfatide sulfatase i.e. arylsulfatase A (ASA). we studied 5/200 cases of MLD and clearly distinguished three clinical forms. One of them presented the juvenile form; two presented the late infantile form; and two other presented the adult form. The Magnetic Resonance Imaging (MRI) of these patients showed a diffuse, bilateral and symmetrical demyelination. The biochemical diagnosis of MLD patients evidencing the low activity of ASA and sulfatide accumulation. PATIENTS AND METHODS: We studied 5/200 MLD patients addressed to us for behavioral abnormalities and progressive mental deterioration. All of them were diagnosed at first by brain MRI evidencing a bilateral demyelination, then the measurement of ASA activity using P-nitrocathecol sulfate as substrate, finally the sulfatiduria was performed using thin-layer chromatography using alpha-naphtol reagent. RESULTS: In this study, from 200 patients presenting behavioral abnormalities and a progressive mental deterioration, we reported just 2 patients were diagnosed as late-infantile form of MLD. Only1 case presented as the juvenile form; and 2 patients with the adult-type of MLD. The brain magnetic resonance imaging (MRI) of all patients showed characteristic lesions of MLD with extensive demyelination. Biochemical investigations of these patients detected a low level of ASA activity at 0°C and 37°C; the excess of sulfatide in sulfatiduria. CONCLUSION: MRI is required to orient the diagnosis of MLD patients; the latter must be confirmed by the biochemical investigations which is based on the measurement of ASA activity and the excess of sulfatide showed in the sulfatiduria.
