Aim: The aim of this study is to present the first total number of tested children in the Federation of Bosnia and Herzegovina and the number of children with positive sweat test. During the study we determined the number of ill children, the median age of children with cystic fibrosis, date of initial diagnosis, an average amount of chloride in the sweat. Material and methods: The study was a retrospective, conducted at the Department of Pulmonology Pediatric Clinic of University Clinical Center of Sarajevo. Results: In the period from March 2003 to December 2014, we have tested 625 children. 351 child were from Sarajevo Canton and 272 children from other cantons. Female children were more affected then male children, in the ratio of 1: 1,105. An average age of female children was 4.19±4.26 years, and the male 2.15±3.11 years. The median concentration of chloride in the sweat measured by sweat test was for male children 103.05±21.29 mmol/L, and for the female children 96.05±28.85 mmol/L. Conclusion: Most of children in Federation of Bosnia and Herzegovina have ∆F508 gene mutation. In the post-war period we started to use a sweat test. Male children tend to live longer than female children with CF.

A case of lung abscessi has been reported in 10 years old child, boy. This lung disease is uncommon, but treatment is complex. A lung abscess is a suppurative process resulting in destruction of the pulmonary parenchyma and formation of a cavity containing purulent material. The child was already treated in the hospital in Bihac since 19.07.2004. to 04.08.2004. Lung abscess was secondary caused by staphylococcus, started as panaritium second finger. The diagnosis is generally made by roentgenographic examination when a cavity with a fluid level surrounded by alveolar infiltration is demonstrated. After a few consultations with thoracal surgeon conservative treatment was continued Vankomicin 40 days and Funzol, later Stanicid 10 days. Brronchosacopy to faciliate drainage or to obtain culture is controversial so the same wasn't done. Surgical drainage of a lung abscess is almost never indicated and resection should be considered only in a children with recurrent hemoptysis, repeated episodis of infection. Serial chest roentgenograms show gradual diminution of the abscessus over a period of several weeks during hospitalization. Last one chest X ray shows as sequely air cyst on the left side. X ray of the second finger shows osteitis of the second phalange. After 40 days the child was discharged with recommendation for follow up by thoracal surgeon next 6 months.
