A linear accelerator with the flattening-filter removed generates a non-uniform dose profile beam. We aimed to analyse and compare plan quality and treatment time between flattened beam (FB) and flattening-filter-free (FFF) beam to assess the efficacy of FFF beam for stereotactic body radiation therapy (SBRT). The sear…

BACKGROUND: The Internet has recently made possible the free global availability of scientific journal articles. Open Access (OA) can occur either via OA scientific journals, or via authors posting manuscripts of articles published in subscription journals in open web repositories. So far there have been few systematic…

The lacrimal sac (LS) is a dilated structure that lies in the lacrimal fossa, and the nasolacrimal duct (NLD) is the continuation of LS from its neck up to the inferior meatus of the nose. A study of 50 specimens of formalin-fixed adult cadavers of both sexes of Indian origin was conducted. The morphological features l…

UNLABELLED: The aim of the study was to evaluate the effect of photocoagulation and range of treatment on visual acuity (VA) in patients with diabetic macular edema. MATERIAL AND METHOD: 56 patients with type II diabetes mellitus--109 eyes were divided into four groups depending on the type of treatment. The evidence…

BACKGROUND: Benign schwannomas, also referred to as neurilemomas, neurinomas, and perineural fibroblastomas, are encapsulated nerve sheath tumors. Primary schwannomas of the liver are extremely rare. We present a case of liver schwannoma, incidentally found in a patient with breast cancer. CASE: A 66-year-old female c…

Accelerated atherosclerosis can lead to an increased prevalence of coronary artery disease, heart failure, brain stroke and peripheral arterial disease. Thus, subjects with chronic renal failure are exposed to increased morbidity and mortality from cardiovascular events. A strong and pervasive link exists between kidne…

Dyspeptic symptoms are quite common in chronic hemodialysis patients, and Helicobacter pylori (cagA(+)) is thought to play an important role in the pathogenesis of the active gastritis and other upper gastrointestinal mucosal lesions in these patients. The aim of this study was to evaluate a probable association betwee…

BACKGROUND: It is assumed that changes in different parts of the host defence mechanisms could influence the outcome by making way for extracranial complications. MATERIAL AND METHODS: For our study we enrolled 121 patients who had sustained various types of severe head injury (GCS 3-8). We investigated several labora…

: Treat to target (T2T) is a strategy that has been increasingly employed in the management of several chronic diseases, with demonstrated improved outcomes. The use of T2T in juvenile idiopathic arthritis (JIA), a common rheumatic disease of childhood, is still in its infancy, and the feasibility of its use in attaini…

OBJECTIVE: This was a cross-sectional study of 150 consecutive patients (105 males and 44 females) with nephrolithiasis. Serum and urine metabolic evaluations were preformed. RESULTS: 70 percent (n=105) of patients were males. Sixty patients (40%) had hypertension. The urine volume of 114 subjects (76%) was less than…

PURPOSE: Our aim was to perform a clinical analysis of small intestinal obstructions caused by surgically treated phytobezoars. METHODS: Twenty-four patients, with small intestinal obstructions caused by phytobezoars, underwent surgery in our department between 1998 to 2008, were reviewed retrospectively. RESULTS: Tw…

The analysis of health and nutrition data from various countries shows many surprising and seemingly incomprehensible facts and paradoxical relationships. Health status of a country is the result of long-term factors and therefore it cannot be changed from day to day. For example in Central European countries there was…

BACKGROUND: Dosage of chemotherapy for colon cancer is currently based on the patient's body surface area. Several studies have identified an association between low fat-free mass and chemotherapy toxicity among patients with metastatic colorectal cancer. This has been less widely studied for localised disease. This re…
