Introduction. Acute pulmonary hypertension leading to right ventricular failure and circulatory collapse is usually caused by a pulmonary embolism. However, in extremely rare cases, similar clinical manifestations can be related to another diseases, such as lymphangitis carcinomatosa. Aim. The purpose of this paper is to report on the case of a 29-year-old male patient presented with rapidly progressing dyspnoea. Description of the case. The diagnosis of pulmonary embolism was made on the basis of echocardiographic signs of pulmonary hypertension and right ventricular (RV) dilatation, and the recommended therapy was introduced. On the suspicion of bronchopneumonia, antibiotics and steroids were applied. However, the previously stated diagnosis of pulmonary embolism was not confirmed by the angio-CT scan, which showed small diffusive lung parenchyma intra-biliary nodules (ground glass opacity) with the peripheral appearance of a tree-in-bud sign. Consecutive CT of pelvis and abdomen along with endoscopy revealed a metastatic gastric cancer with the presence of lymphangitis carcinomatosa and miliary dissemination to the lungs. The presence of pulmonary metastases in the course of disseminated gastric cancer is known in literature as Bard’s syndrome. Conclusion. Extrapulmonary malignancies, particularly gastric cancer, should be taken into consideration in differential diagnosis in patients with an acute right ventricular failure and nonspecific lesions in the respiratory system.

Introduction. Entero-bladder fistula (fistula entero-vesicalis) is a pathological connection between the lumen of the gastrointestinal tract and the bladder. Entero-bladder fistulas are not a common condition. The main reason for the formation of entero-bladder fistulas are intestinal diseases occurring within the intestinal loop adjacent to the bladder resulting in the formation of an abnormal channel, the connection between the above structures Aim. The aim is to present the causes of the fistulas can be divided into congenital and acquired (intestinal infection, cancer, Crohn’s disease, resulting from trauma and iatrogenic). Clinical manifestations of the biliary-bullous fistulae may be from the digestive or urinary tract. The most characteristic ailments are pneumaturia, fecuria, urge to urinate, frequent urination, lower abdominal pain, hematuria, urinary tract infection. Description of the case. The article discusses the case of a patient with Leśniowski-Crohn disease complicated with a bladder-fistula. The treatment of entero-bladder fistulas is primarily surgical, it consists in resection of the fistula together with resection of the affected intestine and bladder wall fragment. Conclusion. The test confirming the presence of an entero-bladder fistula is a test with oral administration of poppies, although it happens that the test result may be negative, especially in the case of a bladder-follicular fistula. Among the tests useful in the diagnosis of entero-bladder fistula include abdominal ultrasound, computed tomography, magnetic resonance imaging, endoscopic tests (colonoscopy or cystoscopy).

Introduction. Glycosaminoglycans (GAGs) play a widespread role in tissue modelling. GAG polymers may affect several receptor pathways in parallel. Aim. To present difference in concentration of GAG in healthy and cancer tissues. Material and methods. The literature search was performed nd reviewed using selected keywords. Results. We revieved the methods of detection various types of glycans measured by Magnetic Resonance Imaging. Conclusion. MRI methodology provides an efficient tool forstudy of cellular composition. The use T1 aof T2 measurements to study cancer tissue is a promising assay.

Introduction. The use of Quantitative Magnetic Resonance Imaging to drug monitoring in vitro or in vivo can provides a powerful means to map the effects of drugs on tissue activity. Aim. The purpose of this study was to measure relaxation time of antibody phantom. For this purpose, infliximab sample was used. Material and methods. The selected methods to detect relaxation time of antibody was Magnetic Resonance Imaging technique. We detected spin-lattice (T1 ) relaxation time and discuss differences where compare to water. Results. The measurements ofspin-lattice (T1 ) relaxation time showed significant differences. The results obtained in phantom indicate that we can use this result for measurements of relaxation time in vitro. Conclusion. Infliximab is approved for severe cases of rheumatoid arthritis, together with methotrexate, for pronounced psoriasis and psoriasis-arthritis, ankylosing spondylitis as well as for chronic inflammatory bowel disease. We conclude, that Quantitative Magnetic Resonance Imaging can be used to monitor drug effects

Aim of the study. In this study, we sought to create a model of reversible hyperoxaluria in pigs by feeding with hydroxyproline (HP). Materials and methods. The experiment included 12 pigs divided into 2 groups (n = 6). The pigs were fed twice a day. At the beginning of the experiment, in the adaptation period, all pigs were given standard feed. In the next 7 days, an increasing amount of hydroxyproline (1–3% HP), was added to the feed. In next 14 days, 4% HP was administered in each pig meal. After 14 days of 4% HP diet, the pigs were randomly divided into 2 groups. For 6 pigs, 4% HP treatment had been continued for the next 14 days while the second group of pigs for the next 14 days received a standard HP free diet. 24h urine samples, blood and fecal samples were collected on particular days. Results. The addition of HP to the diet increased urinary oxalate excretion. A characteristic increase was noted after 12 days of treatment with 4% HP. During the removal period, oxalate excretion decreased in the group without HP in diet, while in the group which continued with a 4% HP diet, oxalate excretion significantly increased. Gross examination of kidneys showed that in the group which had 4% HP diet for 4 weeks, kidneys were fibrotic with enlarged cavities, and had small visible urinary stones. In second group, kidneys were relatively normal looking with no visible stones. Conclusion. Hyperoxaluria is reversible, if HP is removed 14 days after the start of 4% HP diet. Prolonged exposure up to 4 weeks causes pathologic changes in kidneys including crystals, sand and small stone formation.
