Ultrazvuk pluća (LUS), postao je u prvoj deceniji 21. veka sve više i više popularan. Nekoliko radova opisuju prednosti ovog postupka, uglavnom zbog mogućnosti da se koriste u krevetu, bez opasnosti od zračenja, zajedno sa jednostavnim i neposrednim tumačenjem slike. Svrha ovog rada je da predstavi vezu LUS i najčešćih neonatalnih respiratornih bolesti i nekih akutnih plućnih bolesti. Opisali smo tehniku LUS izvršenja, normalan izgled i LUS nalaze sa najčešćim neonatalnim i pedijatrijskim akutnim bolestima. Upotreba LUS na klinici je jednostavna i laka za korišćenje.

Matične ćelije su nespecijalizovane ćelije organizma u vrlo ranom stadijumu razvića, koje u normalnim uslovima u datom tkivu mogu da se diferenciraju u različite tipove funkcionalno specijalizovanih zrelih ćelija. Mezenhimalne matične ćelije (MSCs) su atraktivni kandidati za kliničku primenu u obnavljanju oštećenih tkiva, pogotovu što se mogu izolovati iz više izvora i umnožavati, a njihova primena ne nosi nikakve etičke probleme. Metode izolacije MSCs iz masnog tkiva zasnivaju se na enzimatskom razlaganju dobijenog materijala. Uslovi kultivacije mezenhimalnih matičnih ćelija su temperatura od 37°C i parcijalni pritisak CO2 5%. MSCs se gaje u medijumu, najčešće u a-MEM medijumu sa 10% ili 20% fetalnim telećim serumom. Pod tim uslovima kultivisanja za 7-14 dana adherisane ćelije formiraju kolonije. MSCs su multipotentne i sposobne da se diferenciraju u uslovima in vitro u mezodermalnom pravcu, stvarajući osteoblaste, hondrocite i adipocite. Međutim, one mogu da se diferenciraju i u ćelije ektodermalnog (npr. neurone) i ćelije endodermalnog porekla (npr. ß-ćelije Langerhansovih ostrvaca pankreasa i hepatocite). U Laboratoriji za matične ćelije Departmana za biomedicinske nauke Državnog univerziteta u Novom Pazaru sprovodi se istraživanje MSCs poreklom iz humanog masnog tkiva. U saradnji sa hirurzima Zdravstvenog centra Novi Pazar, a uz poštovanje normi Etičkog komiteta obe ustanove u periodu od 01.07.2011. do 01.07.2012. godine dobijeno je 22 uzorka potkožnog humanog masnog tkiva od ispitanika starosti od 18 do 65 godina. Od 15 uzoraka uspešno je završen proces izolacije i kultivacije, a od 8 i ciljane mezodermalne diferencijacije.

Class III malocclusion are complex anomalies of the skeletal and dental systems. The aim of this study is that the sample of 30 untreated orthodontic patients, aged 18-30 years, rendgencephalometrics analysis closer to determine the mor- phological characteristics of this malocclusion. In patients previously clinically diagnosed class III. For this analysis, were used in a number of cephalometrics points on the basis of which the measured angles and planes. The results were compared with the patients with class I malocclusion and they point to the following morphological characteristics of class III maloc- clusion: a smaller cranial base, normognathic and normal size maxilla, prognathic mandible and chin, the greater the total mandibular length, open gonial angle and a larger anterior and lower posterior facial height.
Key words: malocclusion; morphology; cephalometrics

Introduction: antibiotic prophylaxis in surgical patients is defined as the use of antibiotics to prevented infection of the operating field. Applies in cases where the infection is not clinically manifested. The aim of this paper is to demonstrate the importance of the prophylactic use of antibiotics in the prevention of postoperative infection for patient's inguinal hernia. Materials and methods: The making of the material used Surgical Clinic KBC Pristina in Gracanica, which is part of the "preventive use of antibiotics in surgical patients, through follow-up prospective study of 200 patients. The first group (study group-Group I) consisted of 100 patients with inguinal hernia, in which we apply the prophylactic use of antibiotics. Study group was divided into two subgroups: (Group IA), 50 patients with inguinal hernia in which the solution methods with installation of mesh. (Group IB), 50 patients with inguinal hernia where the tension applied in the treatment methods of treatment. In the second group of patients (control group-Group II) with the same number of patients in the postoperative tre- atment are therapeutic dose used antibiotics. Research results: In our study, the prophylactic purposes, we used compound II generation cephalosporine cefuroxime (Nilacef), which are given in intravenous bolus, the induction of anesthesia, in a dose of 1.5 grams. In 100 patients examined groups, we used prophylactic cefuroxime 100 ampoules (Nilacefa) of 1.5 grams, whi- le the treatment of 100 patients in the control group used for therapeutic purpose 894 ampoules of different antibiotics. Pos- toperative wound infection in patients with prophylactic application of antibiotics are not recorded, while we were in the gro- up where the applied dose of antibiotics therapeutics wound infection noted in two (2%) patients. The average number of days of treatment the study group, the postoperative period was 2.81 days, while patients with a therapeutic dose of antibiotics the average number of days was 5.28. Cost of treatment cefuroksim 50 patients, the prophylactic use amounted to 32,460RSD, while the cost of antibiotics applied in the postoperative treatment of the control group, in which we applied the therapeutic dose antibiotic treatment, was 253,961.52 RSD, which is 7.8 times more expensive. Conclusion: The prophylac- tic application of antibiotics reduced the non-critical use of antibiotics, the incidence of infection of the operating field, mor- bidity and mortality due to postoperative infection, the frequency of resistance to antibiotics, antibiotics to minimize the ef- fect of Bacterian normal flora of the patient, changes in the defense system of the patient, and thus the cost of hospital treat- ment of surgical patients.

Cutaneus melanoma is the most malignant tumor of the skin. Melanoma arises from the malignant transformation of melanocytes at the dermal-epidermal junction or from the nevomelanocytes of atypical melanocytic nevi, that become invasive and metastasize after various time intervals. Dermoscopy is a noninvasive diagnostic technique in dermato- venereology that includes the inspection of the lesion with a handheld dermoscope. Dermoscopy enables the evaluation of the specific morphological structures of the skin that are not visible to the naked eye.therefore, it links clinical dermatology and dermatopathology. The major goal is to differentiate pigmented lesions into melanocytic and nonmelanocytic lesions, and make further differentiations within each group. Furthermore, it is essential to distinguish melanoma from other me- lanocytic and nonmelanocytic skin lesions, and to diagnose melanoma and amelanotic melanoma in their early stages. Der- moscopic follow up includes long-term and short-term monitoring, and is an essential diagnostic technique in the manage- ment of pigmented skin lesions.

Bone and joints tuberculosis is a secondary infection of locomotor system, caused by a Mycobacterium Tuberculo- sis. Low incidence of tuberculosis has been maintained for a long period of time due to use of efficient chemotherapy. Howe- ver, in recent years increasing number of newly registered cases is seen, due to wide use of immunosuppressive therapy, spread of HIV, aging population. Those factors influence mycobacterium more likely to become drug resistant. The objecti- ve of the study is to review epidemiological, clinical,radiology and laboratory findings of bone and joints tuberculosis in our patients, and treatment efficiency. In 15 years of prospective study, 107 different ages male and female adult patients, were treated. In most cases spinal tuberculosis was registered (24%), then hip tuberculosis (17%), knee tuberculosis (16%) and tu- berculosis of sacroiliac joint (7%). Non operative treatment with antitubercular drugs was performed in all patients, while in 41% we used operative treatment. Early diagnosis of bone and joints tuberculosis, while treated with non operative (anti tu- berculosis drugs) and operative methods are preconditions to achieve high percentages of long term remission.

Ocular contusion followed by hyphema is very common ophthalmologic problem. Aim: to determinate basic epidemiologic characteristics, comorbidity of other ocular findings, as well as complications associated with different grade of hyphema. Method: 55 patients with hyphema and ocular contusion were examinated. Results. Male had hyphema almost four times more often then women (80%:20&); workers (34.5%), afterward pensioners (20%) and pupils (18.2%) were the most often injured. The most frequent causes were the wood (43.6%), stone (10.9%) and vegetable foreign body (9.1%), The first grade of hyphema was demonstrated at 30 patients (54.5%), the second at 16 (29.1%), the third at 6 (10.9%) and the fourth at 3 (5.5%). The most frequent associated ocular findings regarding to segments were the following : haematoma palpebrarum, subconjunctival hemorrhage, erosio corneae and haemophthalmus. Secondary glaucoma was the most common ocular complication and it was finding at one patient with the first stage of hyphema but at all patients with the fourth grade of hyphema. Conclusion: grade of hyphema is directly proportional with a grade of ocular complications and frequency of associated ocular findings.

The importance of the examination of life quality of children having asthma is more and more emphasized in the world. Asthma is a disease which limits the persons having this disease in physical, social and mental activities. Information about life quality can only be obtained by the patients because only they have direct insight into their feelings and thoughts. Our research included 95 children having allergic asthma and 40 children having nonallergic asthma were examined. Questionnaire on life quality of children having asthma in the case of general activities PAQLQ(S), whose creator is prof. Elizabeth Juniper, was used for the examination of life quality. The results were shown by questionnaire scores (total and individual ones). Determination of the activities representing the biggest restraints in the life of examined patients gives the possibility for adequate carrying out of therapy as well as better education of the patients concerning self-control of disease.

Epidemiological characteristics of acute stroke certify the great importance of such disease, which takes the measures of a mass incontagious illness, because it represents one of leading causes of death and invalidity in the world. Contemporary knowledge about the complexity of cerebral infarct has been significantly increased thanks to new imaging methods, which allows correction of clinicaly stated diagnose. The aim of our research was to determine clinical manifestation signs of supratentorial infarcts and their presence compared to anatomic localisations of lesions. 60 patients were clinicaly tested, and a computerised tomografy of brain followed, which disclosed anatomic localisation of lesions. Results have shown that the maniestation of supratentorial infarct in the AMC zone has the most neurological signs, from conscious state disorders, graver pyramid deficit, speaking disorder to hemihypesthesia and hemianopsys. Lighter neurological deficit is found in infarcts which affect AAC and APC zones, which brings to a conclusion that knowing the clinical state and without applying neuroradiological methods can imply to localisation of supratentorial infarcts.

There are different stick types and shapes, different root canal preparation techniques, as well as different materials for stick cementing and making annexes around posts. The use of fiber-reinforced resin posts to restore endodontically treated teeth has gained popularity due to its mechanical and esthetic characteristics as well as properties of modern adhesive systems. The aim of this article was to show a clinical technique to reconstruct endodontically treated teeth with great loss of tooth structure using direct fiber-reinforced post systems and direct composite restorations. After the preparation of the root canal and cementation of a FRR post, particular attention was paid to the incremental and curing techniques adopted to reconstruct coronal part of the tooth. It is possible to place of fiber-reinforced resin posts.
