Nodular distribution pattern on chest computed tomography (CT) in patients diagnosed with nontuberculous mycobacteria (NTM) infections.

Background: This study evaluated the prevalence of spreading pathways in nontuberculous mycobacteria (NTM) pulmonary infections according to nodular distribution patterns seen on chest computed tomography (CT).

Methods: This study included 63 patients diagnosed with NTM lung infections who underwent CT at our institution. A retrospective analysis of CT images focused on the presence and distribution of nodules, presence of intrathoracic lymphadenopathy and the predominant side of infection in the lungs.

Morphometric and DNA image analysis of bronchoalveolar lavage fluid macrophages nuclei in interstitial lung diseases with lymphocytic alveolitis.

Lymphocytic alveolitis is a characteristic of diverse interstitial lung diseases (ILD-s), but macrophages are often more numerous cell population in bronchoalveolar lavage fluid (BALF). Aim of this study is to analyze morphometric characteristics of macrophages nuclei in BALF in patients with ILD-s and to detect possible differences allowing distinguishing sarcoidosis from other lymphocytic alveolitis ILD-s. Thirty-one patient with interstitial lung disease who had lymphocytic alveolitis in BALF cell count (17 sarcoidosis and 14 other ILD-s) and nine controls were included in the study.

Prognostic value of computed tomography morphologic characteristics in stage I non-small-cell lung cancer.

Background: In this study, we describe the prognostic value of NSCLC morphologic characteristics obtainable by computed tomography (CT) in the preoperative staging. Starting with the initial hypothesis that CT morphologic characteristics of NSCLC have a prognostic value, we conducted a retrospective study that included 194 patients.

Patients And Methods: All patients underwent surgery because of stage IA or IB non-small-cell lung carcinoma (NSCLC).

[Pulmonary Langerhans' cell histiocytosis--case report].

Authors report a case of a 29-year old patient with pulmonary Langerhans' cell histiocytosis who presented with chest pain as a consequence of rib osteolytic process. We carried out a diagnostic work-up which included laboratory and radiographic analysis, lung function tests, bronchoscopy, cytologic and pathologic analysis. After reaching the diagnosis, corticosteroid therapy was introduced with long-term follow-up.

[Thyroid transcription factor-1 in pulmonary cytology].

Unlabelled: Currently it is necessary to define in almost each case whether a carcinoma is a small or non-small cell carcinoma, adenocarcinoma, pulmonary or metastatic in origin. Thyroid transcription factor-1 (TTF-1) was positive in more than 80% of primary pulmonary adenocarcinomas and in none from the sites other than the thyroid. Mucinous bronchioloalveolar carcinomas are usually negative.

Mycobacterium xenopi pulmonary disease - epidemiology and clinical features in non-immunocompromised patients.

Objectives: The genus Mycobacterium has more than 120 well-characterized species. Although the incidence of tuberculosis has decreased over the studied period, other, non-tuberculous mycobacteria (NTM) are isolated more often. Since, Mycobacterium xenopi is the most frequent NTM isolate in Croatia we studied its epidemiology and clinical relevance.

Recombinant factor VIIa in massive haemoptysis associated with chronic necrotising aspergillosis.

The successful use of recombinant activated factor VII (rFVIIa), in treating massive, life-threatening haemoptysis in a 55-year-old male patient with chronic necrotising aspergillosis, is reported. Patient diagnosed with chronic necrotising aspergillosis three months ago was admitted to our department with massive haemoptysis. Patient was treated as outpatient with itraconazole.

Wegener's granulomatosis of the breast.

Wegener's granulomatosis is a multisystem disorder characterized by necrotizing granulomatous inflammation and vasculitis of small vessels and can affect any organ system. The most common sites of involvement are upper and lower respiratory tracts, and kidneys. Breast involvement is unusual and very rare.

Description of diffuse interstitial lung diseases and assessment of their activity.

Conventional roentgenograms constitute the groundwork for the evaluation of diffuse interstitial lung disease (DILD). ILO classification with its symbols (additionally extended to granulomatoses) does not comprise pathoanatomic assumptions and does not enter lesion genesis for it could lead to diagnostic misconception. "High resolution" computer tomography (HRCT) provides the evaluation of lesion morphology and disease activity.
