Respiration; international review of thoracic diseases

Echinococcus disease is endemic in sheep-and cattle-raising areas world wide. Its prevalence is also high in the Mediterranean region including Turkey. ⋯ In conclusion, hydatidosis is still an important public health problem in Turkey and in an endemic country such as Turkey hydatid lung disease should be considered initially in a patient presenting with a corresponding chest roentgenogram and a compatible epidemiologic history. Surgery is indicated in all symptomatic and/or enlarging or infected cysts. When necessary lobectomy or wedge resection can be the procedure of choice. Single-stage combined resection is preferred in hydatid lung disease with associated liver hydatid cysts. Total postoperative complication and mortality rate is low and we recommend a close follow-up of the operated cases to diagnose postoperative recurrence early in its course.

Crohn's disease can be associated with several respiratory manifestations. We report here a case of pulmonary migratory infiltrates associated with bilateral pleural thickening and peripheral eosinophilia. The histopathological findings show an association of necrotizing nodules, eosinophilic infiltration in the non-abscessed lung tissue, areas of non-caseating epithelioid granulomas, and an extensive pleural fibrosis. The different histopathological findings are detailed and the responsibility of either Crohn's disease or treatment by mesalazine is discussed.

Randomized Controlled Trial Clinical Trial
Placebo-controlled study of inhaled budesonide on indices of airway inflammation in bronchoalveolar lavage fluid and bronchial biopsies in cross-country skiers.
Asthma-like symptoms, methacholine hyperresponsiveness, use of inhaled steroids, airway inflammation, and increased tenascin expression in the reticular basement membrane have been reported in competitive cross-country skiers. ⋯ We were unable to show any clear beneficial effect of budesonide in 'ski asthma'. As changes in training intensity probably accounted for the spontaneous improvement in bronchial responsiveness, more attention should be directed at reducing environmental stress to the airways than at attempting pharmacological modulation of induced inflammatory changes.

Cystic fibrosis (CF) is caused by mutations in the CF transmembrane conductance regulator (CFTR) gene which encodes a protein expressed in the apical membrane of exocrine epithelial cells. CFTR functions principally as a cAMP-induced chloride channel and appears capable of regulating other ion channels. Besides the most common mutation, DeltaF508, accounting for about 70% of CF chromosomes worldwide, more than 850 mutant alleles have been reported to the CF Genetic Analysis Consortium. ⋯ Besides patients with atypical CF, there are large numbers of so-called monosymptomatic diseases such as various forms of obstructive azoospermia, idiopathic pancreatitis or disseminated bronchiectasis associated with CFTR mutations uncharacteristic for CF. The composition, frequency and type of CFTR mutations/variants parallel the spectrum of CFTR-associated phenotypes, from classic CF to mild monosymptomatic presentations. Expansion of the spectrum of disease associated with the CFTR mutant genes creates a need for revision of the diagnostic criteria for CF and a dilemma for setting nosologic boundaries between CF and other diseases with CFTR etiology.

Trepopnea is a condition whereby breathing may be comfortable in one position but difficult or labored in another. A unique case with trepopnea due to recurrent lung cancer with right main pulmonary artery stenosis and left main bronchus obstruction is presented. ⋯ An emergent wall stent implantation was performed via the right femoral vein in the sitting position with the patient's leg stretched out. The symptoms and respiratory function improved after stent implantation.
