Use of functional magnetic resonance imaging in patients with irritable bowel syndrome and functional dyspepsia.

Functional brain imaging (positron emission tomography - PET, functional magnetic resonance imaging - fMRI), allowing in vivo analysis of the brain-digestive tract interaction and the neurological mechanisms underlying visceral hypersensitivity, significantly advanced research and helped in the understanding of the interrelations in this field. Differences in this parameter can result from alterations in task-related cognitive states or from resting state processes. Nowadays, advanced imaging techniques such as fMRI are more frequently used and are acknowledged among both clinicians and radiologists in the diagnostic algorithm of digestive tract diseases. Functional dyspepsia is a condition in which neuroimaging allows for analysis of dysfunctions within the brain-gut axis (BGA) engaged in processing of visceral discomfort and pain. The results of studies in patient groups with irritable bowel syndrome prove that psychosocial factors significantly affect the mechanisms regulating visceral sensitivity within the brain. The BGA includes neuronal pathways (autonomic nervous system), neuroendocrine (hypothalamo-pituitary-adrenal axis), and neuroimmunological ones. Psychological processes affect the functioning of the digestive system and can cause dyspeptic symptoms. A patient's mental condition associated with stress can affect processes taking place in the central nervous system and trigger somatic reactions in the digestive tract through the autonomic visceral system.

Analysis of safety, risk factors and pretreatment methods during rush hymenoptera venom immunotherapy.

BACKGROUND: The safety profile of venom immunotherapy is a relevant issue. We evaluated the frequency of severe adverse events (SAE), associated risk factors, retrospective comparison of pretreatment protocols including solely H1 receptor blockers and a combination of H1 and H2 receptor blockers during rush Hymenoptera venom immunotherapy. METHODS: The study group comprised 118 patients. The treatment was initiated according to a 5-day rush protocol with the use of standardized venom allergens of either wasp or honeybee. RESULTS: During the rush induction, side effects occurred in 18 patients (15.2%), whereas SAE were present in 7 patients (5.9%). Twelve out of 18 (66.6%) developed anaphylactic reactions on the fourth day of the rush protocol, with the majority of cases at a dose of 40 or 60 microg of the venom extract (p = 0.001). The frequency of SAE was also significantly higher on the fourth day than thereafter (p = 0.0001) as well as in patients allergic to bee venom (p = 0.049). All systemic side effects were more frequent in women (p = 0.0065). However, this relation was not true when SAE were consider (p = 0.11). A higher percentage of SAE was observed in the subjects pretreated with both H1 and H2 receptor antagonists than in those pretreated with H1 blocker only (8.8 vs. 4.1%); however, the difference was not significant. CONCLUSIONS: Considerable severity of allergic adverse events requires particular attention to patients allergic to bee venom and during rush phase, especially when rapidly increasing doses are administered. Pretreatment with H2 blockers is debatable and warrants further investigation.

[The effects of pulmonary rehabilitation on the quality of life in patients with COPD]. / Wplyw rehabilitacji na jakosc zycia u chorych na przewlekla obturacyjna chorobe pluc.

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity, hospitalization and disability among lung diseases. Its chronic, progressive nature and acute exacerbations influence the quality and expectancy of life of COPD patients. The pulmonary rehabilitation is a basic non-pharmacological intervention in COPD and its role is increasing in recent years. The goal of this work was to evaluate the impact on quality of life patients undergoing 3 weeks pulmonary rehabilitation program. MATERIAL AND METHODS: 132 patients with COPD were admitted to pulmonary rehabilitation program; 70 completed the 3 weeks long program. Pulmonary function tests, exercise endurance, quality of life (St. George's Respiratory Questionnaire) were measured at baseline, 3 weeks, and 3 months. RESULTS: There was significant improvement in quality of life in St. George's Respiratory Questionnaire and exercise endurance (treadmill) measured at 3 weeks and at 3 months. Parameters of lung function tests did not improved after completion of rehabilitation. CONCLUSIONS: 3 weeks pulmonary rehabilitation program of patients with COPD was effective in improving exercise endurance and the quality of life. The improvement was noted as well at 3 months post rehabilitation.

[Latent tetany masked by syndroms of bronchial asthma and depressive syndrome. Case report]. / Astma oskrzelowa i zespól depresyjno-lekowy maskujace utajona tezyczke. Opis przypadku.

Tetany, which occurs in young women, poses common diagnostic problem. Two types of tetany are distinguished: one which is characterized by hypocalcemia and which rarely occurs (in person after strumectomy in the course of post-operational hypoparathyroidism) and latent one, which occurs more often. In the literature there is a lack of precise data concerned witch most probably results from its underestimation. Clinical symptoms which appear in latent tetany (normocalcemic) are related to the intracellular magnesium deficiency and increased respiratory drive. A noncharacteristic clinical picture and the lack of a pathognomonic symptom, cause that despite of the fearly common occurrence, the latent tetany is rarely recognized. In this paper the case of a 53 year old women has been described. The women had the symptoms of gastroesophageal reflux of asthma and depressive syndrome, witch masked the symptoms of the latent tetany.

[Malignant mesothelioma of the pleura--diagnostic difficulties]. / Zlosliwy miedzybloniak oplucnej--trudnosci diagnostyczne.

Malignant mesothelioma of the pleura is a rare neoplasm with a poor prognosis. Noncharacteristic clinical signs, radiological features and similarity to other neoplasma (adenocarcinoma) in a microscopical evaluation lead to often diagnostic problems. Thoracoscopy followed by biopsy is routinely performed and is considered a main diagnostic procedure. Microscopic samples are usually examined by immunohistochemical analysis. In this report, presented is a case of malignant pleural mesothelioma, in which final diagnosis was delayed because of difficulties in diagnosis based on thoracoscopic biopsy.
