Usefulness of laboratory data in estimation of Crohn's disease activity.

Crohn's disease (CD) is a chronic inflammatory disease characterized by unpredictable and severe course. Most clinicians use simple laboratory parameters of inflammatory activity such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), the number of leukocytes (Le) and platelet count to assess disease activity. The aim of this paper was to determine the value of various laboratory parameters in the assessment of Crohn's disease activity. The study included 36 patients, 15 men and 21 women, treated for Crohn's disease at the Gastroenterohepatology Clinic, Clinical Centre, University of Sarajevo, in period 2006 and 2007. Assessed patients were divided into three groups, according to the degree of disease activity, which was determined using the Crohn's Disease Activity Index (CDAI). Mild disease (MD) was present in 15, moderately severe disease (MSD) in 14, and severe disease (SD) in 7 patients. Statistical significance of association between values of laboratory parameters with the degree of severity of illness was investigated using the 95% Confidence Interval test. CRP showed a statistical significance for the relationship between MD-MSD (95% CI 6,645-74,333) and the relationship between MD-SD (95% CI 4,114-135,278), while the relationship between MSD-SD was not statistically significant. MPV showed statistical significance only for the relationship between MD-MSD (95% CI 0,060-2,909). Sedimentation rate and the number of red blood cells showed statistical significance for the relationship MD-SD (95% CI 10,638-62,943 and 0,077-1,080). Haemoglobin, hematocrit and platelet count showed statistical significance for the relationship between MD-MSD and MD-SD. Number of leukocytes did not show any statistically significant relationship with clinical activity of disease. The most reliable indicators of activity of Crohn's disease in this study were CRP, MPV, haemoglobin, hematocrit and platelet count, while leukocyte number did not correlate with disease activity. Neither parameter was sensitive enough to distinguish the relationship between moderately severe disease and severe disease. Until finding a "gold standard" for assessment of clinical disease activity, various laboratory and other parameters must be combined and compared with other indicators, such as endoscopic findings and radiological results.

Congenital malformations of the central nervous system: clinical approach.

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.
