Background: AIDS is now a pandemic in children. Asymptomatic children with human immunodeficiency virus (HIV) infection cannot be distinguished from children without infection. Opportunistic infections are common in children with AIDS. Aims: Describe the prevalence of human immunodeficiency virus acquired immunodeficiency syndrome (AIDS) among all children with opportunistic infections in Bosnia. Methods: The control group was composed of six boys and six girls for every year age class between one day and six years. Children were included from the study when they presented with a opportunistic infectious disease at the time of planned investigation assessment. Results: Children are underrepresented among recipients of antiretroviral therapy in almost every setting in Bosnia where treatment programs have been established. HIV-affected children and HIV-infected children had a significantly poorer socioeconomic living standard compared with control children. Ninety percent of the sample had been diagnosed with HIV before three years of age; the mean age of diagnosis for this sample was eleven months. Among the groups at highest risk for suprainfections of HIV infection were newborns from infected SIDA mothers. Conclusions: The prevention of opportunistics HIV infections in children and its consequent illness must be the primary component of any education program. Pediatricians and specialist for infectious diseases can play an important role in educating parents about opportunistic infection of HIV prevention, transmission, and testing, with an emphasis on risk reduction.

The report deals with the case of a 10-year-old girl with chronic cystic fibrosis. She has been repeatedly treated at the hospital. She has been hospitalized due to respiratory deterioration. Cystic fibrosis is a rare disease, inherited autosomaly recessively, but is very complex in terms of diagnostic and treatment (2). The diagnosis is confirmed based on a clinical picture of the child, measure of Chloride in the sweat, chest X-ray, CT thorax, laboratory findings--genetic confirmation CFTR ( cystic fibrosis transmembrane conductance regulator) genes (3), which result in the production of hyper-viscous mucus and chloride malabsorption in the sweat glands ducts (5,6). Bronchial thickening and plugging and ring shadows suggesting bronchiectasis, segmental or lobar atelectasis are often. Computer tomography of the chest can be used to detect and localize thickening of bronchial airways walls, mucus plugging, hyperinflation and early bronchieactasiae. Pulmonary therapy: the object is to clear secretions from airways and to control infection (7). The diagnosis is originally set when she was 4 years old. She is now admitted due to a deterioration of the main disease. Day before admission in the hospital had a higher bodily temperature, cough and difficult breathing. She already treated conservatively (Ceftazidim, Ceftriakson, Kloksacillin) Since the girl is a chronic patient with bronchiectasie chronic walls of bronchi changes full of the mucus, who is not responding to conservative treatment (antibiotics), therapeutic and diagnostic flexible bronchoscopy had to be performed, resulting in a gram-negative bacteria pseudomonas aeruginosa--a typical bacteria for chronically sick C. F. patient. A pseudomonas therapy was prescribed according to the sensitive antibiogram, during which bronchoscopy was given locally on changes mucous pulmozyme and garamycin. Flexible bronchoscopy was performed as therapeutic. Local bronchoscopy findings:by aspiration of tracheo-bronchal truncus it was found hyperemia and a lot of mucous sticky secretion inside of tracheobronchal tree, especially middle lobe right side, lingual and basals part of the lungs. It was performed broncho-alveolar lavage and given steroids on the place of changed inflamed mucous membrane of the bronchi. It was also given pulmozyme to destroid mucous and make better spontaneously expectorations. Control chest x ray was performed and it was better.

The paper presents the case of a 4-year-old child who was admitted with the diagnosis Dg: Pleuropneumonia lat. sin, while in the further course as a suspicion due to progressive flow as staphylococcus pneumonia. The illness is complex in terms of treatment. The diagnosis was set based on the history of illness, its clinical course, laboratory findings, radiology tests. The boy was hospitalized in January in current year with symptoms (coughing, vomiting and fever) that have been lingering for the past two days. The boy has been treated with a ternary antibiotic therapy (cephalosporin of third generation parenterally with aminoglycosides, plus anti-staphylococcus therapy). In laboratory findings Sedimentation rate increased 88/134 WBC 75 thousands. Radiologically extended pleuropneumonia on the left side. In sputum staphylococcus aureus was isolated. In the further course of hospitalization, due to the development of progressive form of staphylococcus pneumoniae with a fever of up to 39 degrees, pale aspect and dyspnoic patient with anemia and with complications in the form of cysts, ruptures and pneumothorax, with a thoracic drainage performed. In the further course, the cysts were gradually absorbed, while the thoracic drain was grafted. Clinically, the child was looking better. We continued the anti-staphylococcus therapy (stanicide), to which the child reacted well clinically and radiologically. Auscultatory breathing on the left side was audible. The last follow-up and the last rtg pulmo et cor 6 months after the outbreak of illness with a complete regression of the foregoing changes.

The report deals with the case of a 10-year-old girl with chronic cystic fibrosis. She has been repeatedly treated at the hospital. She has been hospitalized due to respiratory deterioration. Cystic fibrosis is a rare disease, inherited autosomaly recessively, but is very complex in terms of diagnostic and treatment. Fibrosis is the formation of scar tissue due to injury or long term inflammation. The diagnosis is confirmed based on a clinical picture of the child, measure of Chloride in the sweat, chest X-ray, CT thorax, laboratory findings--genetic confirmation CFTR genes. The diagnosis is originally set when she was 4 years old. She is now admitted due to a deterioration of the main disease. Five days before the admission, the girl had a higher bodily temperature, cough and difficult breathing. Due to the deteriorated general condition and the respiratory insufficiency and respiratory acidosis in blood gas analysis, the girl was intubated and put on the complete mechanical ventilation (IPPV). Since the girl is a chronic patient with bronchiectasie chronic walls of bronchi changes full of the mucus, who is not responding to conservative treatment (antibiotics), therapeutic and diagnostic flexible bronchoscopy had to be performed, resulting in a gram-negative bacteri Pseudomonas aeruginosa--a typical bacteri for chronically sick C. F. patient. Pseudomonas aeruginosa is typically acquired in early childhood. This bacteria is giving progressive lung disease and often aggravates morbidity and mortality. So the main thing as a respiratory management is prevention of lung infection with this bacteria. A Pseudomonas therapy was prescribed according to the sensitive antibiogram, (Garamycin). Antibiotics are crucial to treating cystic fibrosis lung infections. Therapy with an amynoglicoside in combination with a B-lactam or a quinolone antibiotic is standard. It is a difficult to deliver a high doses at these antibiotics via the iv. route without significant systemic adverse events (otoxicity and nephrotoxicity). A reformulation of the aminoglycoside antibiotic tobramicin or garamycin therapy is solution for inhalation. To be well established infections the suppression of Pseudomonas aeruginosa has been shown to lead to decreasing same bacteria and benefits lung function from antibiotic therapy in a way that can be maintained over extended period. During bronchoscopy was given locally on changes mucous pulmozyme (to destroy a very hard mucous) and garamycin. So, after taking out a lot of mucus, it was later continued spontaneously. Control chest x ray and blood gas analysis are now very improved.

A case of sarcoma Ewing hemithorax lst sin has been reported in an 8-year-old girl. The girl was admitted in our hospital with referral diagnosis Pleuropneumonia exudativa left side. The girl was sent from Nova Bila with the foregoing diagnosis. The difficulties started in early April this year with high body temperature, pains in the left side of the chest. After a detailed anamnesis, clinical picture of the girl and radiological examinations/ chest x ray, CT scan of the chest and operative findings/ sarcoma Ewing diagnosis was confirmed. The disease is very rare, while diagnostics and course are complex. The girl was admitted at the Pulmology Department of the Pediatric Clinic on 16.03.2005. At the Department, the girl was medically treated with three antibiotics: cephalosporins of third generation, ceftriaxon (Longacef), aminoglycoside Amikacin and antistaphyloccoc therapy (Orbenin). Due to a dull sound on percussion and weaker auscultatory breathing on the left, and radiological shading of the left chest, a CT of the thorax was performed. It showed expansive changes of the left chest. Also performed was a pleural punction of the left chest, after which around 500 ml sero-hemorrhagic content was taken out and sent for patohistology analysis. After a pre-operative preparation, the operation was performed on 28.03.2005, which is when a fat-like tumorous mass was found completely filling up the pleural cavum and by its weight exerting pressure on the lungs. In the projection of VI and VII rib, the described mass infiltrates the thoracic wall. The tumor extirpation "in toto" was performed and sent for patohistology analysis, ex tempore. Also performed was a pleuropectomy in the projection of the wall infiltration, as well as a partial resection of the VII rib. Also performed was a decortication of the visceral pleurae. The post-operative course has been passing normally and with good pleuropulmonary findings, with the wound healing per primum. Patohistology results: sarcoma Ewing hemithorax lat. sin. The girl continued her cytostatic therapy in Zagreb following the operation.

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.
