This paper presents the most common disorders of pituitary function: acromegaly, hypopituitarism, diabetes insipidus and syndrome similar to diabetes insipidus, in terms of their importance in preoperative preparation of patients. Pituitary function manages almost the entire endocrine system using the negative feedback mechanism that is impaired by these diseases. The cause of acromegaly is a pituitary adenoma, which produces growth hormone in adults. Primary therapy of acromegaly is surgical, with or without associated radiotherapy. If a patient with acromegaly as comorbidity prepares for non-elective neurosurgical operation, then it requires consultation with brain surgeons for possible delays of that operation and primary surgical treatment of pituitary gland. If operative treatment of pituitary gland is carried out, the preoperative preparation (for other surgical interventions) should consider the need for perioperative glucocorticoid supplementation. Panhypopituitarism consequences are different in children and adults and the first step in diagnosis is to assess the function of target organs. Change of electrolytes and water occurs in the case of pituitary lesions in the form of central or nephrogenic diabetes insipidus as a syndrome of inappropriate secretion of antidiuretic hormone (SIADH). Preoperative preparation of patients with pituitary dysfunction should be multidisciplinary, whether it is a neurosurgical or some other surgical intervention. The aim is to evaluate the result of insufficient production of pituitary hormones (hypopituitarism), excessive production of adenohypophysis hormones (acromegaly, Cushing's disease and hyperprolactinemia) and the influence of pituitary tumours in surrounding structures (compression syndrome) and to determine the level of perioperative risk. Pharmacological suppressive therapy of the hyperfunctional pituitary disorders can have significant interactions with drugs used in the perioperative period. Source

Purpose: To investigate the influence of the angiogenesis parameter CD34 microvascular density (MVD) on overall survival of colorectal cancer (CRC) patients. Methods: Thirty-one CRC patients were followed-up for 72 months after curative colorectal operation. Blood vessels measurement was done using the CD34-MVD immunochemistry method, and light microscopy. Results: MVD was inversely correlated with patients' survival. MVD value < 35 proved as independent good prognostic factor, and patients with this value lived during the 72-month follow up after surgery, while a MVD value > 65 was an independent poor prognostic factor and such patients died within 11 months after radical surgery for CRC (p<0.01). Conclusion: According to these results, the CD34-MVD seems to be a significant prognosticator of overall survival in CRC patients. © 2012 Zerbinis Medical Publications. Source

Aim To compare efficacy and toxicity of bolus application of chemotherapy protocol, oxaliplatin, fluorouracil (bolus), leucovorin (folfox) between two groups of patients in the therapy of metastatic colorectal carcinoma (mCRC). Methods A total of 63 patients were treated for mCRC in the period January 2009 - January 2010 at the Department of Oncology of the Cantonal Hospital Zenica, Bosnia and Herzegovina (first group, 30 patients) and at the Department of Oncology of the Clinical Hospital Centre Bezanijska kosa in Belgrade, Serbia, in the period January 2005 - January 2006 (second group, 33 patients). The patients were treated according the same protocol, i.v. bolus infusion, but in different day intervals (D), 1, 8, 15/28 days or D1- D5/28 days, respectively. In all patients the following factors were analyzed: tumor response, overall survival (OS), progression free survival, hematological and non-hematological toxicity . Results Colon was the primary localization in almost two thirds of patients. There was no statistically significant difference between the groups according to the age, hematological and non-hematolo- gical toxicity, as well as in achieved OS. Progression free survival expressed in months was in average 5 months though with a large range between minimal and maximal survival time. Conclusion Both groups have shown equivalent efficacy to applied chemotherapy protocols. Overall survival in the two groups matched data from the literature. Further research should confirm success of the combination of chemotherapy protocols and their combination with the biological therapy. © 2015, Medical Association of Zenica-Doboj Canton, All rights reserved.

Antiphospholipid syndrome (APS) or Hughes syndrome represents a systemic autoimmune disorder characterized by arterial and/or venous thrombosis, multiple and recurrent fetal losses, accompanied by persistently elevated levels of antiphospholipid antibodies (aPL). This syndrome is considered primary if unassociated with any other connective tissue disease, or secondary if it appears in association with other autoimmune disorders, mainly systemic lupus erythematosus. Cardiac manifestations in APS are integral part of the syndrome. aPL are involved in the pathogenesis of pseudoinfective endocarditis (Libman Sacks) and other valvular manifestations presented as their thickening and dysfunction. Intracardiac thrombi and myxomas, pulmonary hypertension and left ventricular dysfunction are also distinguishing features of APS. On the other hand, accelerated atherosclerosis, proven in APS and also aPL mediated, is accountable for the development of coronary and peripheral artery disease. This leads to higher cardiovascular mortality rate in the population of patients with low incidence of the traditional atherosclerosis risk factors. Furthermore, recent studies implied that presence of certain aPL could be a risk factor for a specific cardiac manifestation. Bearing all this in mind, early diagnosis of cardiac manifestations, control and abolition of traditional risk factors, as well as close cardiac follow-up of APS patients, are crucial in reducing their cardiovascular mortality. © 2015, Serbia Medical Society.

Background: The aim of this study was to analyze the demographic and clinical characteristics of male breast cancer patients in Serbia, and furthermore to determine overall survival and predictive factors for prognosis. Materials and Methods: In the period of 1996-2006 histopathological diagnosis of breast cancer was made in 84 males at the Institute for Oncology and Radiology of Serbia. For statistical analyses the Kaplan-Meier method, long-rank test and Cox proportional hazards regression model were used. Results: The mean age at diagnosis with breast cancer was 64.3±10.5 years with a range from 35-84 years. Nearly 80% of the tumors showed ductal histology. About 44% had early tumor stages (I and II) whereas 46.4% and 9.5% of the male exhibitied stages III and IV, respectively. Only 7.1% of male patients were grade one. One-fifth of all patients had tumors measuring ≤2 cm, and 14.3% larger than 5 cm. Lymph node metastasis was recorded in 40.4% patients and 47% relapse. Estrogen and progesterone receptor expression was positive in 66.7% and 58.3%, respectively. Among 14.3% of individuals tumor was HER2 positive. About two-thirds of all male patients had radical mastectomy (66.7%). Adjuvant hormonal (tamoxifene), systematic chemotherapy (CMF or FAC) and adjuvant radiotherapy were given to 59.5%, 35.7% and 29.8% patients respectively. Overall survival rates at five and ten years for male breast cancer were 55.0% and 43.9%, respectively. According to the multivariate Cox regression predictive model, a lower initial disease stage, a lower tumor grade, application of adjuvant hormone therapy and no relapse occurrence were significant independent predictors for good overall survival. Conclusions: Results of the treatment would be better if disease is discovered earlier and therefore health education and screening are an imperative in solving this problem. Source
