[Isolation and identification of Burkholderia cepacia complex from cystic fibrosis patients].

In this study, sputum samples collected from cystic fibrosis patients with preliminary diagnosis of pulmonary infection were evaluated for the presence of bacteria belonging to Burkholderia cepacia complex by commercial phenotypic systems and recA polymerase chain reaction (PCR). A total of 85 patients ages between 5-30 years (mean age: 12.8 years) were included to the study with female/male ratio of 44/41. The mostly isolated bacteria from 85 sputum samples were found as Staphylococcus aureus (55.3%), Pseudomonas aeruginosa (48.2%) and Haemophilus influenzae (15.3%), whereas B. cepacia complex was phenotypically identified from two (2.3%) out of the samples. However only one was confirmed by PCR and typed as Burkholderia multivorans by restriction fragment lenght polymorphism method. This study emphasizes the importance of molecular methods as confirmatory tests for accurate identification of B. cepacia complex.

Bronchiectasis: the consequence of late diagnosis in chronic respiratory symptoms.

Bronchiectasis is still common among some developing countries like Turkey. The aim of this study was to document the number of children with non-cystic fibrosis (CF) bronchiectasis, to evaluate the risk factors and to emphasize early diagnosis and treatment. All children, except those diagnosed with CF, with bronchiectasis established by chest radiogram, bronchography and/or computed tomography or biopsy material, were retrospectively reviewed. They were tested for serum total eosinophil count, nasal smear, serum levels of immunoglobulins A, G, M, E, and serum alpha-1 antitrypsin level. Pulmonary function tests, rigid bronchoscopy, nasal biopsy, lung scintigraphy, and echocardiogram were also performed. There were 204 patients whose most common presenting symptoms were cough, sputum expectoration, and dyspnea. Bronchiectasis was present mostly in the left lower lobe. The cause could not be determined in 49 per cent of patients. Among the identified causes, infection was present in most patients, followed by asthma, primary ciliary dyskinesia, congenital immune deficiency, and foreign body aspiration. It is possible to prevent bronchiectasis in children with vaccinations and improved nutrition in developing countries. Early diagnosis and treatment will increase the quality of life and survival of patients with bronchiectasis, which has irreversible and progressive complications if untreated.

Medical treatment of pulmonary hydatid disease: for which child?

There have been many encouraging studies on medical treatment of pulmonary hydatid disease due to Echinococcus granulosus infection. Our aims were to demonstrate the safety and efficacy of medical treatment in pulmonary hydatid disease and to describe a pediatric population who would benefit from medical treatment, especially in respect to the diameter of the hydatid cyst. All patients were treated with mebendazole or albendazole. Treatment outcome was defined as cure, improvement or failure. Among 82 patients, 34.1% were cured, 34.1% improved and 31.8% failed. When 102 cysts were individually evaluated, 36.31% were cured, 32.4% improved and 31.3% failed. The cure and the failure rates were statistically insignificant in cysts treated with mebendazole and albendazole; however statistically significantly more cysts were improved with albendazole. The results were statistically insignificant between continuous and cyclic albendazole treatment. The mean size of successfully treated cysts was 5.3+/-3.4 cm, but "failed" for cyst with a mean size of 7.3+/-4.3 cm. There was a positive, weak and statistically significant correlation between the cyst size and treatment results. The major complication was infection. We suggest that selected pediatric patients with uncomplicated pulmonary hydatid cysts sized less than 5 cm should have a trial of medical treatment with a very close follow up.

Clinical features and treatment approaches in cystic fibrosis with pseudo-Bartter syndrome.

INTRODUCTION: Infants with cystic fibrosis (CF) are prone to develop episodes of hyponatraemic, hypochloraemic dehydration with metabolic alkalosis, which are biochemical hallmarks of the pseudo-Bartter syndrome (PB). METHOD: We reviewed the clinical and laboratory features and treatment approaches of 29 children with CF and PB who were under follow-up in our institution from May 1992 to November 2003. RESULTS: Of 241 patients with CF, PB was detected in 29 (12%) with a median age of 4 months at the time of the first attack. Most patients experienced vomiting, loss of appetite and dehydration during episodes of PB. All patients were managed with intravenous fluids and sodium chloride solutions. During follow-up, 12/29 cases required hospital admission for recurrent PB attacks. The oldest age at the time of the last attack was 48 months. CONCLUSIONS: CF should be considered in the differential diagnosis of metabolic alkalosis in young children. Vomiting and loss of appetite are important warning signs of possible PB in CF patients, particularly before 4 years of age. To prevent serious complications, it is crucial that parents and physicians recognise PB as early as possible.

Cardiac hydatid cyst and pulmonary hydatidosis in a child.

Hydatidosis in the lungs is unusual, and a cardiac localization occurs rarely. We report a child with cardiac hydatid cyst that developed during albendazole treatment for preceding multiple pulmonary hydatid lesions. The cardiac lesion was treated by surgical excision, and the pulmonary cysts improved with a combination of praziquantel and albendazole therapy.

Postinfectious bronchiolitis obliterans in children: clinical and radiological profile and prognostic factors.

BACKGROUND: Postinfectious bronchiolitis obliterans (BO) designates a clinical syndrome of chronic airflow obstruction associated with inflammatory changes in the small airways. OBJECTIVES: The aim of this study was to determine the etiology, clinical and radiological features and define prognostic factors of postinfectious BO in children. METHODS: We undertook a review of the medical records of 20 children with postinfectious BO, who were followed up between January 1994 and August 2001. RESULTS: Postinfectious BO was diagnosed in 11 boys and 9 girls with a median age of 21.5 months (6-69 months) who were followed up for a median of 23 months. Cough and wheezing persisted since the initial lung infection in all patients. Postinfectious BO was diagnosed in an average of 6 months (1-42 months) after the acute illness. Adenoviruses were the most common etiologic agents identified serologically. The diagnoses of postinfectious BO was made by thoracic high-resolution computed tomography and clinical features. Corticosteroid therapy was used in 17 patients and supportive treatment was applied in all patients. Age at initial lung infection, gender, time of starting corticosteroid treatment, presence of bronchiectasis or atelectasis and etiologic agents identified on presentation did not predict severity in our study. CONCLUSIONS: Despite the prominent role of inflammation in the pathogenesis of postinfectious BO, the use of anti-inflammatory agents remains controversial. We could not identify any prognostic factors related to disease severity. In order to minimize associated complications, patients with postinfectious BO should be closely followed up and receive meticulous lung care.

BALF nitrite as an indicator of inflammation in children with cystic fibrosis.

BACKGROUND: A unique substance reflecting the degree of inflammation localized to the lower respiratory tract in patients with cystic fibrosis (CF) has been the concern of several investigators and nitric oxide has gained interest for this purpose in the last decades. OBJECTIVES: The aim of this study was to evaluate the cytokine and nitrite levels by showing the relationship between them in serum and bronchoalveolar lavage fluid (BALF) of patients with CF and patients in which flexible fiberoptic bronchoscopy (FFB) was applied because of indications other than infection. METHODS: 20 children with CF with mean age 8.2 years and 10 children as control group with mean age 4.2 years were included in the study. Cultures for aerobes, anaerobes, fungi and mycobacteria, cell differentials, cytokine and nitrite measurements were made from BALF specimens. White blood cell (WBC) count, erythrocyte sedimentation rate (ESR), quantitative C-reactive protein (QCRP), cytokine and nitrite levels were measured from serum samples. RESULTS: BALF neutrophil, TNF-alpha, IL-8 and nitrite levels were significantly higher in patients with CF than control patients. There was no correlation between serum and BALF cytokine and nitrite levels. However, there was a significantly positive correlation between BALF IL-8 and nitrite levels in patients with CF (r = 0.5) and also in control patients (r = 0.6). CONCLUSIONS: The results suggest that BALF nitrite levels reflect the degree of inflammation localized to lower respiratory tract and may be a useful indicator of airway inflammation for patients with CF.

Tracheomalacia and bronchomalacia in 34 children: clinical and radiologic profiles and associations with other diseases.

We reviewed our experience on tracheomalacia (TM) and bronchomalacia (BM) in children who presented with chronic respiratory problems and evaluated their clinical and radiologic characteristics and their associations with other disorders. There were 26 males and 8 females with a median age of 9 months. The main symptoms were wheezing, persistent or recurrent pneumonia, and chronic cough. Atelectasis on chest radiograph was the most common sign. Of 23 children with TM, 1 had a double aortic arch, 1 had tracheoesophageal fistula, and 1 other had associated laryngomalacia. BM was found in 27 children and was predominantly seen on the right side. TBM was found in 16 cases (in an infant TBM was accompanied by pharyngeal dyskinesia and in another by laryngomalacia). Malacia disorders were associated with gastroesophageal reflux, cardiovascular anomalies, and tracheoeosophageal fistula. TM and BM should be considered in the differential diagnosis of children with chronic and recurrent respiratory symptoms. Early diagnosis of malacia disorders will prevent unnecessary use of antibiotics or antiasthmatic drugs, which are often abused to treat these children. In these patients, treatment for associated diseases should also be considered.

Using computer based data acquisition and analysis system for nasal potential difference measurement in cystic fibrosis.

Nasal potential difference (PD) measurement has been used as a diagnostic test for cystic fibrosis (CF). It has been shown that large differences in reproducibility of nasal PD measurement can exist between different study sites. These differences reduce the validity of studies. In our study we tried to measure nasal PD values for a group of Turkish CF patients by using a computer based data acquisition system, which could eliminate the bias due to using different voltmeters. The CF group (n=40, mean age 9.3 years) value was -39.21+/-1.74 mV, and the control group (n=36, mean age 17.08 years) value was -18.24+/-1.48 mV (mean+/-SEM). Using the electronic data acquisition and analysis systems gave reliable results with high specificity (92%), sensitivity (79%), positive predictive value (95%) and negative predictive value (72%). Computer based data acquisition and analysis system provides suitable monitoring and continuous recording during measurements and facilitates repeat readings at the same distances along the nasal floor. Using electronic data acquisition may help to minimize the subjectivity in voltmeter measurements and hand analysis.
