Introduction: Dental caries is the most common oral disease in all age groups. Being more and more frequent in preschool and school-age children, it has become one of the most important problems in oral pathology. The aim of this study was to determine the incidence of dental caries in schoolchildren aged 12 and 15 years in the northern part of Kosovo and Metohija, as well as to inform them about the importance of oral health. Materials and Methods: The study included 626 schoolchildren of both sexes from five schools from the municipalities of Kosovska Mitrovica, Zvečan and Leposavić. Klein-Palmer DMFT system (D-Decayed, M-Missing, F-filled) was used to estimate the prevalence of dental caries the following indices were also used: Person Caries Index, Teeth Caries Index, Average Caries Index and DMFT structure. All the selected children were examined using standard dental diagnostic agents. Tooth surfaces were examined dry under artificial lighting. Results: The average value of DMFT index for children aged 12 and 15 years was 4.2. On average, 92.3% of the examined children had caries. The mean value of caries index was 15.11%.Conclusion: After these new epidemiological studies, it can be concluded that the state of children's oral health, considering the high levels of untreated caries and all other features of DMFT index, is not satisfactory. This situation points to the necessity of applying modern preventive and prophylactic measures to preserve and improve the population oral health.

Introduction: Sapho syndorm is a syndrom characterizing with osteoarticular end dermatologic symptoms. Acronym „SAPHO“ means: S-Sinovitis, A-Acne, H-Hyperostosis, O-Osteytis. SAPHO syndrom has a 50 different names in existing literature. For now, etiology remains unclear, but it belongs to group of seronegative spondylarthropathies. Therapy of SAPHO includes NSAIL, glucocorticosteroids, disease modifying anthireumatic drugs (DMARD), antibiotics, bifosfonatos, and anti TNF - alfa drugs with variable success. Case outline: Pacent P.Z, 47 age, female, comes in the hospital, because of pain in anterior chest, with propagation in right arm, end morning stiffness in sacral part, which passes short after. Also, with recidivant pustules on the palms, bilaterally, which precedes itch. Bone scintigraphy was performed: There is a clear increasing binding of radiopharmacs in projection of strenoclavicular joint, and slightly in both shoulders and both knees. HP: Pustulosis palmoplantaris. We introduced in therapy azithromycin in the dose of 500 mg, two times weekly, for 16 weeks. Patient, one year after, is without relapses of arthritis and skin lesions. Conclusion: This report has goal, to get more knowledge about this rare disease, and to be easier for recognition. Also we want to introduce other physicians, of varying specialities, like orthopaedics, and other surguries, with this disease, not only rheuamatologists, dermatologists, and pediatrics.

The panoramic radiography is the most used diagnostic imaging method in planning impacted lower third molar extractions. However, often panoramic radiography does not provide enough information in treatment planning for performing safely surgical extraction of impacted third molars. CBCT (Cone beam computed tomography) provides more precise information in diagnostic analysis especially for planning surgical procedures where complications can be expected due to close relationship between mandibular canal and lower impacted third molars. The aim of this study is comparative analysis of panoramic radiography and CBCT in evaluating the topographic relationship between mandibular canal and impacted third molars. The study included 50 patients with close relationship between mandibular canal and impacted third molars detected using panoramic radiography. After panoramic radiography analysis CBCT was performed in order to diagnose, plan and prevent complications during the surgical tooth extraction. CBCT examination considered comparative analysis with panoramic radiography, marking, volume rendering and assessment of mandibular canal in buccolingual direction. Out of total patients where suprimposition of mandibular canal and impacted third molar on panoramic radiography was detected, in 32 patients mandibular chanal was localised on lingual side. Mandibular canal was positioned at bucal side in 18 of 50 patients. Results of this research indicate that panoramic radiography can be useful in everyday practice for diagnosis, planning and preparing lower third molar extractions, but in cases where close relationship between mandibular canal and lower third molars is detected CBCT is recommended as more precise radiographic imaging method in order to prevent complications.

Hepatitis A is an acute viral disease of the liver caused by the hepatitis A virus (HAV) .In many areas of the world represents a significant epidemiological problem, and the infection is usually transmitted by contact, rarely contaminated water and food. The main objective of the study was to identify the most important epidemiological characteristics of hepatitis A in Serbian areas of Kosovo and Metohija. We used the data of reporting of infectious diseases, reports on infectious diseases (seven-day, month, year) of the Department of Public Health Pristina in Kosovska Mitrovica. In our research we used epidemiological Studies of cross-section (crosssectional). Between 2003-2015. in Kosovo and Metohija (Serbian middle) registered 223 cases of hepatitis A. The average incidence in the reporting period was 11.03 / 10,0000. Analysis of age distribution revealed that the most common incidence in people aged 15-19 years, and the rarest people aged 50-59 years. Hepatitis A occurs throughout the year, showing seasonal variations. Trend of incidence shows a negative trend with a reduction in the number of cases in the territory of Kosovo and Metohija. Based on the results of our study we can conclude that hepatitis A is an important public health and socioeconomic problem. In order to prevent hepatitis A, it is important to continue to improve hygiene and sanitary conditions of life as the best general preventive measures.

Diabetes mellitus is one of the most common non-communicable chronic diseases, which is the combined action of genetic factors, environmental factors and lifestyle. Specific conditions occur in the oral cavity in the course of diabetes that cause changes in all oral tissues with different symptoms and signs. Increased salivary glucose level is followed by increased accumulation of dental plaque and decreased resistance to noxious agents. The most common oral manifestations in diabetic patients include higher prevalence of periodontal desease, burning mouth syndrome, disruption in salivary flow, opportunistic infections, higher prevalence of denture stomatitis, oral lichen planus, fissured tongue, angular cheilitis etc. Dental interventions in patients with well-controlled diabetes are not different from those applied to nondiabetic patients. Regular monitoring of these patients is required because of the complications that can occur.

Cardiovascular complications are the major cause of mortality and morbidity in children with end-stage renal disease who are treated with chronic hemodialysis Arterial hypertension is a major cardiovascular risk factors in this population. The aim is that children who are on HD displays the prevalence of hypertension, to check arterial pressure before and after HD and displays the correlation with the left ventricle mass (LVM). Method: The study in 20 patients on chronic HD and 20 healthy control group children, blood pressure was measured by sphygmomanometer before and after HD. Also echocardiography were measured left ventricular mass before and after HD and track the correlation of these two parameters. Results: The prevalence of hypertension in children on HD is 62% for significant different compared to the control group (p <0.001) .. TA values of systolic and diastolic significantly lower after HD. (P <0.05). After HD TA values were significantly higher than the value of TA (p <0.05) in healthy children. The prevalence of LVH was 60% in children on HD and statistically be statistically highe then to the control group (p <0.001). The correlation between LVH and increased TA was linear but was not statistically significant in either group of patients. In conclusion: The fact that hypertension does not correlate significantly with left ventricular mass suggests that the increase in LVM except high blood pressure and affect other cardiovascular risk factors.

Necrotizing otitis externa, also known as malignant type of the inflammatory process, represents an infection of the skin of external hearing canal, a fast development of tissue necrosis and infection spreading to the surrounding structures. Basic clinical characteristics are: strong earache, leaking from ear, granulation findings at the bottom of the hearing canal, the disorder of hearing function and a potential possibility of complications (paralysis of facial nerve, intracranial infections). Mycrobiologically the most present bacerium is Pseudomonas aeruginosa. Other microorganisms that can be isolated are Aspergillus species, Staphylococcus aureus, Proteus mirabilis, Klebsiella oxytoca, Candida parapsilosis. The disease is more common in patients with general diseases, mostly of metabolic nature (diabetes mellitus). The approach to diagnosis and therapy is usually urgent in order to prevent the development of serious complications. This paper shows the results of the analysis of clinical process of malignant otitis in 25 patients from the Clinic of ORL and MFS KCS according to the type of the cause and the development of potentially severe and life threatening complications.

The most important characteristic of calcium channels is selective regulation of slow incoming stream of calcium into the cell tissue providing the slow increasement of action potential. Such tissues include smooth muscles of blood vessels, cardiocytes and heart noduses (AV and SA node). Different calcuim antagonists have different effects on previous tissues due to their different chemical formula. Verapamile, Nifedipin and Diltiazem are the most frequently used of all. Their commonest characteristic is blocking the calcium channels causing vasodilatation of blood vessels as well as negative inotropic and chronotropic influence. By blocking the incoming calcium through slow channels of myofibrils of smooth muscles, the antagonists of calcium decrease the quantity of available calcium for contraction which causes vasodilatation. The most famous and most frequently used calcium antagonist is Verapamile. In terms of electrophysiology, Verapamile inhibits action potentials of heart noduses, especially the AV node, where the slow incoming of calcium is the most important for depolarization. Prolongation of the efective refractory period of SA node causes the heart frequency decreasement while prolongation of the effective refractory period of AV node slows down the work of chambers in case of flater and fibrillation of atriums. The molecules of calcium-bonding protein called kalmodulin are located in synaptic endings. Each kalmodulin can bond four calcium ions providing transfer into active calcium-kalmodulin complex which activates the kinase protein. Activated kinase protein starts the exocytosis of neurotransmitters into synaptic gap. Apart from activating kinase protein, calciumkalmodulin complex also starts the activity of calcium pump presynaptic membrane which pumps calcium out of presynaptic ending stopping the further exocytosis of neurotransmitters into synaptic gap. Taking into consideration the fact that opening the calcium channels on membrane of presynaptic ending is necessary to free the neurotransmitter out of the vesicle, the aim of our work is to study whether Verapamile has effects on the membrane of presynaptic endings of sympathetic nervous system checking the level of catecholamine in serum. The experiment was conducted in 6 healthy dogs which were, after 10-minute- infusion (0.9% NaCl), treated with intravenous bolus veramapile injections in three occasions, in every 5 minutes, until the first signs of intoxication had appeared. This caused bradycardia, heart rhythm disorder and blood pressure drop. In order to determine the level of catecholamine, blood was taken sequentially, in every 5 minutes, before the new dose of verapamile was given. Verapamile (given intravenous) significantly decreases the concentration of adrenaline and noradrenaline in the serum of dogs.
