Osteoporosis and osteoarthritis are two different medical conditions, which beside the first part of their name „osteo“, have very little in common. Osteoporosis is a disorder which influences bones in terms of reduction of quality and quantity, which can easily result in bone fracture. Clinical signs of osteoporosis show no pain or other symptoms which could point to changes in bone structure, unless a bone fracture is diagnosed. Osteoarthritis is a disease which influences joints and its surrounding tissues. Seeing through clinical signs, changes could be verifi ed in terms of pain and limitations of movement and the cause of pain and way of its treatment are numerous. A person can suffer from osteoporosis and osteoarthritis at the same time. Although these medical conditions are more frequent in female than in male population, mechanisms which lead to them may interfere. Osteoporosis and osteoarthritis are muscular-bone disorders with signifi cant morbidity and mortality, but clinical experiences and epidemiological studies have shown their negative correlation.

Intracranial dermoid cysts are congenital, usually nonmalignant lesions with an incidence of 0.5% of all intracranial tumors. They tend to occur in the midline sellar, parasellar, or frontonasal regions. Although theirnature is benign, dermoid cysts have a high morbidity and mortality risk, especially when rupture occurs. A 40 year old woman presented with head injury after she experienced sudden loss of consciousness. She hada history of headache, loss of consciousness; her past medical history was not remarkable. The patient had no complaints of nausea, vomiting, or seizures. Vital signs were stable, neurologic defi cit was not identifi ed.Computed tomography (CT) and magnetic resonance imaging (MRI) showed right temporobasal zone with fat droplets within right fi ssure Sylvii and interhemispheric fi ssure indicating a rupture of a dermoid cyst. Craniotomy and cyst resection were done, and diagnosis was confirmed with pathological examination following surgery. After surgery the patient did not recover. Cerebral ischemia from chemical meningitis was fatal forour patient. Headache as a symptom has many causes. It is rarely due to chemical meningitis arising from a ruptured dermoid cyst. This case report illustrated the importance of investigating a cause of the headache,CT and MRI being diagnostic methods. In this way, mortality as well as morbidity from complications such as chemical arachnoiditis can be significantly reduced if imaging is done early in these patients.

Introduction: This study is the fi rst study about the distribution ABO blood types at children with acute leukemia in Federation of Bosnia and Herzegovina. The aim of the study is to point out distribution of blood type groups at children with acute leukemia (AL)Methods: The number of children in this study was the following: 145 children with acute leukemia and 27 of children with acute myeloblastic leukemia (AML). All of the children were treated at Hemato- Oncology Unitof Pediatric Clinic in Sarajevo, in the period January 2000 until December 2010. Age of children was between 1 month and 15 years.Results: The results showed that different blood types were registered in 93. 1% of children who got ill and treated from acute leukemia for the mentioned period. At 6. 9 % of children, none of the blood types wereregistered. It was noticed that 40.9 % children who have registered blood type O, 37% blood type A,16% blood type B and 6.5% blood type AB had AL, too. It has been observed that children with following bloodtypes had AML: O, 47.8%, A, 47.7% and AB, 30.4%.Conclusion: Signifi cance ABO types distribution was confi rmed for children with ALL, p<0, 05. The analysis of the distribution of ABO types based on gender showed that signifi cance was confi rmed at females with both ALL and AML (p<0.05).

Introduction: Several decades of basic science and animal research provided considerable support for significant role of plasma free fatty acids (FFAs) in etiology of Type 2 diabetes mellitus (T2DM). Contradicting data related to signifi cance of elevated FFAs in plasma of patients with Type 2 diabetes prompted us to study concentrations of palmitic acid, stearic acid, and linoleic acid, in patients and healthy controls in an attempt to possibly use them as potential biomarkers in progression of the disease. Since aging is associated withincreased plasma glucose and insulin levels that are consistent with an insulin resistant state, in this study,age differences in the concentration of the above mentioned acids were tested.Methods: Progressive changes in their concentrations were followed through a period 6 months. All subjects included in the study were free of evidence of hepatitis B or C viral infection or active liver and kidney damage. Analysis of glucose and glycated hemoglobin levels were performed on BT PLUS 2000 analyzer using standard IFCC protocols, while concentrations of FFAs were analyzed by gas chromatography.Results: Our data demonstrated signifi cantly higher FFA values in plasma of diabetic patients as compared to healthy controls. There was a trend of correlation of FFAs levels with the blood glucose levels in diabetic patients, which was more prominent in diabetic men than in women.Conclusion: With aging, levels of free fatty acids signifi cantly increased in plasma of diabetic patients, and this effect was also more profound in male than in female diabetics.

Introduction: Present study describes the antimicrobial activity and free radical scavenging capacity (RSC) of essential oil from Mentha longifolia (L.) Huds. Aim of this study to investigate the quality, antimicrobial andantioxidant activity of wild species Mentha longifolia essential oil from Bosnia and Herzegovina.Methods: The chemical profi le of essential oil was evaluated by the means of gas chromatography-mass spectrometry (GC-MS) and thin-layer chromatography (TLC). Antimicrobial activity was tested against 6bacterial strains. RSC was assessed by measuring the scavenging activity of essential oils on 2,2- diphenyl-1-picrylhydrazil (DPPH).Results: The main constituents of the essential oil of M. longifoliae folium were oxygenated monoterpenes,piperitone oxide (63.58%) and 1,8-cineole (12.03%). Essential oil exhibited very strong antibacterial activity.The most important antibacterial activity essential oil was expressed on Gram negative strains: Escherichia coli, Pseudomonas aerginosa and Salmonella enterica. subsp.enterica serotype ABONY. Antioxidant activity was evaluated as a RSC. Investigated essential oil was able to reduce DPPH radicals into the neutral DPPHH form (IC50=10.5 μg/ml) and this activity was dose –dependent.Conclusion: The study revealed signifi cant antimicrobial activity of the investigated essential oil. The examined oil exhibited high RSC, which was found to be in correlation to the content of mainly monoterpeneketones and aldehydes. These results indicate that essential oils could serve as safe antioxidant and antiseptic supplements in pharmaceuticals.

Introduction: Intramedullary nailing is synthesis and  consolidation of fracture fragments with the main goalto gain strength and permanent placement of the implants. Two techniques of intramedullary osteosynthesis are used: with dynamic or with static intramedullary nail. Dynamization include conversion of static nail by removing screws from the longest fragment. The aim of this study is to determine whether there is a difference in the speed and quality of healing of the type A and B fractures of the femur and tibia treated by static or dynamic intramedullary nails and to compare the results.Methods: The study was conducted on a total of 129 patients with closed fractures of the diaphysis of the femur and tibia type A and type B. Patients were divided into two groups, based on the applied operating method, static or dynamic intramedullary osteosynthesis.Results: The average number of weeks of healing femoral and tibial fractures was slightly in advantage of static intramedullary osteosynthesis, it was 17.08 weeks (SD=3.382). The average number of weeks of healing in 23 patients with fractures of the femur, treated by dynamic intramedullary osteosynthesis was 17.83 (SD=2.978).Conclusion: We can conclude that static intramedullary nailing osteosynthesis unable movements between fragments which directly stimulates bone formation and formation of minimal callus. Static intramedullary ostesinthesys resolve the problem of stabilizing the fracture, limb shortening and rotation of fragments.

This issue of the International Journal of Nephrology focused on kidney diseases within a devil's triangle, oxidative stress (OS), mediators, inflammation, specifically relating to the clinical significance of identification, and prevention. Every creature in need of oxygen faces OS. It has a critical role in the molecular mechanisms of renal injury in several kidney diseases, and many complications of these diseases are mediated by OS, mediators, and inflammation. There is a complex relationship between these three; mostly they induce each other. While some of the diseases themselves can contribute to OS, reactive oxygen species (ROS) produced by activated leukocytes and endothelial cells in sites of inflammation cause tissue damage. Although inflammation looks dangerous for the organism, it is a normal reaction of organs and tissues to protect themselves against several invasion(s). It enables the immune system to remove the injurious stimuli and initiate the healing process of tissues. However, the interactions between OS, mediators, and inflammation may result in glomerular damage, proteinuria, electrolyte, and volume instabilities which cause nephron loss, on the long view. Detailed studies on this topic are included in this issue. The kidney can easily be damaged by ROS, due to the rich structure of long-chain polyunsaturated fatty acids. The article by E. Ozbek summarizes the induction of OS within kidney in several conditions, including diabetes, hypertension, hypercholesterolemia, obesity, aging, urinary obstruction, environmental toxins, and molecular mechanisms of these inductions in the light of existing literature data. Diabetic nephropathy is one of the most common microvascular complications of type 1 and type 2 diabetes mellitus and the leading cause of end-stage renal disease worldwide [1]. Rojas-Rivera et al. reviewed the biological bases of oxidative stress and its role especially on diabetic nephropathy, as well as the role of the Keap1-Nrf2 pathway, and recent clinical trials targeting this pathway with bardoxolone methyl, a novel synthetic triterpenoid with antioxidant and anti-inflammatory properties. Obesity continues to be a public health problem throughout the world. Epidemiologic studies have shown that 66% of adults and 16% of children and adolescents are overweight or obese [2]. Obesity-related glomerulopathy is an increasing cause of end-stage renal diseases. J. Tang et al. stressed the chronic low-grade systemic inflammation in obesity and discussed the roles of inflammation and oxidative stress in the progression of obesity-related glomerulopathy and possible treatment modalities to prevent kidney injury in obesity, such as the usage of anti-IL-6 receptor antibody, TNF-α antagonist, adiponectin, nutritional and surgical interventions to reduce OS. Hypertension is an another important global health issue both in adults and children. It is one of the major risk factors for the progression of kidney diseases. The relationship between blood pressure and dietary sodium and salt sensitivity has been well known, and renal sodium handling is a key determinant of long-term blood pressure regulation [3]. There is a limited knowledge in the literature regarding the role of ROS-mediated fibrosis and renal proximal tubule sodium reabsorption through the Na/K-ATPase. S. Liu et al. reviewed the possible role of ROS in the regulation of Na/K-ATPase activity. The authors emphasized the importance of further researches whether ROS signaling is a link between the Na/K-ATPase/c-Src cascade and NHE3 regulation and how OS, stimulated by high salt and cardiotonic steroids, regulates Na/K-ATPase/c-Src signaling in renal sodium handling and fibrosis. Urotensin-II is the most potent mammalian vasoconstrictor identified to date, almost tenfold more potent than endothelin-I [4]. A. Balat and M. Buyukcelik discussed the role of urotensin-II on renal hemodynamics and its possible role on several kidney diseases, such as the minimal change nephrotic syndrome. The article includes a detailed discussion of urotensin-II immunoreactivity in renal biopsy specimens of children with membranoproliferative glomerulonephritis, membranous nephropathy, IgA nephropathy, Henoch-Schonlein nephritis, and focal segmental glomerulosclerosis. Because of its complex relation with OS and other mediators, authors describe it as “more than a mediator” in glomerular diseases. They briefly mention from the effectiveness of U-II antagonism, as a new promising pharmacological treatment target in some kidney diseases. Given the potential impact of OS, mediators, and inflammation trio, the importance of prevention has come into question. Strong evidence indicates the importance of new molecules that are able to diminish them which in turn may help to decrease the prevalence and/or progression of several kidney diseases. Therefore, further researches are needed to the better understanding of the molecular and clinical mechanisms of this triad. They may help to provide new therapeutical strategies to control several complications in patients with kidney diseases. Ayse Balat Halima Resic Guido Bellinghieri Ali Anarat

Beside the historical overview of the broader area, this paper will also encompass the technical analysis of medieval tombstones and a grave tumulus on the site of Mramorje in the village Raonići, in Kaoštice, municipality of Višegrad. The site is located on a small hill, next to the road which was used in the time of the Illyrians. The road led from Međeđa, across the right side of the River Drina, over Kaoštice to Strgačina, connecting the lower Polimlje with the land of the noble family Pavlovići. It was used in the period of Austro-Hungarian rule over Bosnia and Herzegovina (1878-1918). Due to the preserved information in the medieval documents, we know that the region of Kaoštica was not a part of the Pavlovići property, but it is also interesting that the family of Vladimirić-Radosalić stemmed from Kaoštice (Koštice) and that members of this family were counts of lower status on the Pavlovići court.
