Systemic onset Juvenile Idiopathic Arthritis (SoJIA) is rare pediatric disease, it accounts for 10% of children with Juvenile Idiopathic Arthritis. The onset of disese can be vary nonspecific and may suggest bacterial or viral infection, malignancy or other rheumatic disease. It is highly characterised by its extra-articular systemic illness features and, in some ways, it resembles a fever of unknown origin. Diagnosis is mostly clinical by using ILAR criteria (International League of Associations for Rheumatology).

Antiphosphospholipid syndrome (APS) secundary to systemic lupus erythematosus (SLE) can be recognised in children with arterial or venous thrombosis. Amaurosis due to thrombosis of central retinal vene is rarely presenting manifestation of SLE with secondary APS.

Catatonia is a rarely reviewed clinical feature of neuropsychiatric (NP) manifestation of pediatric systemic lupus erythematosus (pSLE). It is a state of neurogenic motor immobility, and behavioral abnormality manifested by stupor.

Common variable immunodeficiency (CVID) or acquired hypogammaglobulinemia is the type of primary immunodeficiency. Deregulation of the immune system, leading to hypogammaglobulinemia, defective activation and proliferation of T cells and dendritic cells, and malfunction of the cytokines are observed in CVID. The clinical picture of CVID varies, any organ or system can be affected, therefore the diagnosis is often difficult and delayed and sometimes is not always possible. This article describes a twelve years old boy with all the clinical signs of immunodeficiency, as confi rmed by laboratory. The main treatment consists of life-long immunoglobulin substitution in intravenous or subcutaneous form.

Central nervous system (CNS) malformations represent important factor of morbidity and mortality in children. The aim of the study was to determine the incidence, type and clinical features of CNS malformations in children who were admitted at the Neonatal and Child Neurology Department, Neonatal Intensive Care Unit and Paediatric Intensive Care Unit of Paediatric Clinic, University of Sarajevo Clinics Centre, from January 1st, 2002 to December 31st, 2006. There were total of 16520 admissions at the Paediatric Clinic over the studied period. CNS malformations, solitary or multiple, have been diagnosed in 100 patients (0,61%). The total number of various CNS malformations was 127. Lethal outcome was established in 9/100 cases (9%). The most frequent CNS malformations were neural tube defects 49/127 (38,6%). Hydrocephalus was seen in 34/127 (26,8%), microcephaly in 24/127 (18,9%), agenesis of corpus callosum in 10/127 (7,9%), Dandy Walker malformation in 6/127 (4,7%) and other CNS malformations in 4/127 (3,1%). In 20/100 of patients neural tube defect was associated with hydrocephalus (20%). CNS malformations were prenatally diagnosed in 13/100 of patients (13%). Primary prevention of CNS malformations can be improved in our country by better implementation of preconceptional folic acid therapy for all women of childbearing age. Secondary prevention by prenatal diagnosis requires advanced technical equipment and adequate education of physicians in the field of foetal ultrasonography. In our circumstances, prenatal diagnostics of CNS malformations is still not developed enough.
