Pyridoxine-dependent epilepsy: report on three families with neuropathology.

Pyridoxine-dependent epilepsy (PDE) is a pharmacoresistant epileptogenic encephalopathy controlled by pyridoxine supplementation at pharmacological doses. Despite supplementation, the long-term outcome is often poor possibly because of recurrent seizures and developmental structural brain abnormalities. We report on five patients with PDE from three unrelated families.

Report of the Tunisian Registry of Primary Immunodeficiencies: 25-Years of Experience (1988-2012).

Purpose: Primary immunodeficiencies (PIDs) are a large group of diseases characterized by susceptibility to not only recurrent infections but also autoimmune diseases and malignancies. The aim of this study was to describe and analyze the distribution, clinical features and eventual outcome of PID among Tunisian patients.

Methods: We reviewed the record of 710 patients diagnosed with Primary Immunodeficiency Diseases (PIDs) from the registry of the Tunisian Referral Centre for PIDs over a 25-year period.

Tuberculous meningitis in Bacille Calmette-Guerin-vaccinated children: clinical spectrum and outcome.

The Bacille Calmette-Guérin vaccination (BCG) contributed widely to reduce tuberculosis incidence in developing countries. The aim of this report was to assess the clinical "spectrum" and outcome of tuberculous meningitis in 16 Bacille Calmette-Guérin-vaccinated Tunisian children. They were 9 boys and 7 girls aged 2 to 168 months (median 72 months ± 65.

Antiphospholipid antibodies: lupus anticoagulants, anticardiolipin and antiphospholipid isotypes in patients with sickle cell disease.

Antiphospholipid antibodies were investigated in 37 individuals with sickle cell disease and compared to a control group of 30 healthy subjects. Sickle cell patients included 18 homozygous sickle cell patients, 8 S/beta thalassemic patients and 11 sickle cell trait subjects. In all individuals, antiphospholipid antibodies were explored by lupus anticoagulant (LA) detection and the quantification of IgG and IgM anticardiolipin (aCL) isotypes, total antiphospholipid antibodies (APA) and IgM, IgG and IgA antiphospholipid classes.

Abnormalities of coagulation and fibrinolysis in homozygous sickle cell disease.

Abnormalities of coagulation and fibrinolysis were studied in a group of 28 children and young adults with homozygous sickle cell disease (SCD), either in the steady state (n = 12) or during painful crisis (n = 16). Coagulation was explored by standard clotting tests and by measurement of prothrombin complex factors, factor VIII (VIII:C) and antithrombin III (ATIII), protein C (PC) and protein S (PS) activities, while fibrinolytic potential was evaluated using D-dimer, tissue plasminogen activator (t-PA) and plasminogen activator inhibitor (PAI-1) assays. In SCD patients, thrombin time (TT) was constantly shortened, both in the steady state (ratio to control 0.

[Study of a custom in Somalia: the circumcision of girls].

Female circumcision and infibulation is a common practice in parts of Africa. The present report describes the results of a study conducted in Somalia during Operation "Restore Hope". Using pre-defined questionnaire, a total of 300 women and 70 men were interviewed in order to evaluate the prevalence of this practice in Somalia, the procedures used, and the psychologic implications for the population.

[Hereditary hyperoxaluria or oxalosis. Apropos of a case].

We report a case of primary oxalosis in a 12-year old girl. This unusual observation exemplifies two diagnostic pitfalls, i.e.
