Dependence of exhaled breath composition on exogenous factors, smoking habits and exposure to air pollutants.

Non-invasive disease monitoring on the basis of volatile breath markers is a very attractive but challenging task. Several hundreds of compounds have been detected in exhaled air using modern analytical techniques (e.g.

Intrahepatic transposition of bile ducts.

Objective. To describe the intrahepatic bile duct transposition (anatomical variation occurring in intrahepatic ducts) and to determine the frequency of this variation. Material and Methods.

Morphometric changes of the lumbar intervertebral space following discectomy on one or two levels.

Aim: To investigate a potential difference in postoperative morphological changes of two-level lumbar disc surgery as compared to one level surgery.

Methods: The standard lateral radiographs of lumbar spine obtained preoperatively and postoperatively were used in the study . The morphological study included 60 adult patients of both sexes who had undergone the surgery in the period 2002-2006.

[Chronic epidural haematoma mimicking meningioma].

The study presents a rare case of organised chronic epidural haematoma that imitated a meningioma. A patient was admitted to the Department of Neurology of the Cantonal Hospital Zenica due to loss of consciousness and right hemiparesis. Non-contrast Computed Tomography (CT) scan had shown an expansive intracranial process in the left parietal region which was radiologically diagnosed as a meningioma.

Noninvasive detection of lung cancer by analysis of exhaled breath.

Background: Lung cancer is one of the leading causes of death in Europe and the western world. At present, diagnosis of lung cancer very often happens late in the course of the disease since inexpensive, non-invasive and sufficiently sensitive and specific screening methods are not available. Even though the CT diagnostic methods are good, it must be assured that "screening benefit outweighs risk, across all individuals screened, not only those with lung cancer".
