Različita oboljenja pluća se na radiogramu grudnog koša mogu manifestovati u obliku solitarnih perifernih kružnih plućnih promena. U najvećem procentu radi se o tumorima pluća i to najčešće o karcinomu bronha perifernog tipa. Po učestalosti zatim dolaze tuberkulozne, bakterijske, gljivične, parazitne, infekcijske lezije kao i metastaze na plućima. Ostala oboljenja su zastupljena u znatno manjem procentu. Ovakve periferne plućne lezije su uglavnom asimptomatske i otkrivaju se slučajno. Veličine su 3-6 cm u prečniku. Lokalizovane su u desnom plućnom krilu, apikalno znatno češće, u odnosu na levo plućno krilo. Kod tuberkuloznih lezija u 50 % slučajeva prisutne su kalcifikacije, a najčešće su zastupljeni tuberkulomi. Periferne solitarne plućne lezije mogu pričinjavati značajan dijagnostički problem što iziskuje primenu mnogih dopunskih metoda ispitivanja do konačne dijagnoze i primene adekvatnog lečenja.

Povrede u sportu su relativno česte i mogu biti akutne i hronične, kao i endogene i egzogene. Na obim i učestalost povređivanja mogu uticati brojni faktori, kao što su loša kondicija, mišićni disbalans, anatomske anomalije, nutritivni faktori i period rasta. Nakon zbrinjavanja i lečenja sportske povrede sledi rehabilitacija i procena takmičarske sposobnosti pojedinca od strane lekara na osnovu prirode povrede, bolne osetljivosti, vremenskog faktora, poređenjem sa zdravim ekstremitetom, funkcionalnim ispitivanjima. Pravilna evaluacija takmičarske sposobnosti nakon povrede je važan faktor prevencije eventualnog povređivanja u kasnijim sportskim aktivnostima pojedinca.

Strenuous exercises greatly increase oxygen consumption in the whole body, especially in skeletal muscles. Large part of oxygen consumption is reduced to H2O and ATP, but smaller part (2-5%) results in an increased leakage of electrons from the mitochondrial respiratory chain, forming various reactive oxygen species-ROS (02, H2O,iOH). These free ra- dicals are capable of triggering a chain of damaging biochemical and physiological reactions (oxidative stress, lipid peroxi- dation), as a base for skeletal muscles damage after exercise. MDA (malondialdehyde) is a marker of exercise induced lipid peroxidation process. L-ascorbic acid is a major aqueous-phase antioxidant. To estimate antioxidant role of ascorbic acid we use rate between dehydroascorbate and ascorbate. In this paper those markers of lipid peroxidation (MDA, MDA ind, % ind MDA), and ascorbic acid status (ascorbic acid Asc, ascorbat A, dehidroascorbat DHA, DHA/A) were determinated in 30 stu- dents, in rest and after treadmill running protocol (Bruce Treadmill Protocol). It was found that after the treadmill test, plas- ma MDA level had increased from 3,04 to 4,39 M/L (p<0,0001) and % ind MDA decreased significantly from 35% to 24,7% (p=0,0003). Plasma ascorbic acid was also found to be higher after the treadmill test comparing to rest level (from 55,4 to 67,6 μM/L). DHA/A level in rest was 1,62 and after treadmill test it increased to 2,05 (p=0,0014). These results suggests that strenuous exercise increased process of lipid peroxidation (MDA †, % ind MDA), but in the same time incre- ased ascorbic acid level in plasma and DHA/A rate indicates stronger activation of nonenzymatic antioxidant defense system.

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.

Many research projects that deal with the transformations of morphological characteristics have pointed out their extensive complexity, considering the fact that they are the result of genetic factors (endogenic influence) as well as factors pertaining to the environment (exogenic factors), where it is necessary to point out that the influence of genetic factors is not the same for all of the latent morphological dimensions. Òhe different positions of the biacromial and bicristal range in the latent and taxonomic structure of morphological characteristics that have contributed to the actualization of the problem of the relation between the first and second horizontal axis of the body, as well as their relations to the other components of morphological status. Taking that viewpoint, we defined the aim of this research to identify those morphological characteristics which are to the greatest extent related to the development of the horizontal axes. Using a sample of 130 athletes, handball players (N=70) and soccer players (N=60), aged 16 to 27, all of whom play in national leagues, and using a system of 21 anthropometric variables, we analyzed the relations between the first and second horizontal axis of the body, and their connection to the development of the remaining morphological characteristics. The first horizontal axis was defined as the biacromial range and the other as the bicristal range, while the remaining morphological characteristics were defined as the 19 standard measurements of longitudinal and transversal dimensionality, volume and body mass, and subcutaneous fatty tissue. When calculating the connection between the first and second horizontal axis and the remaining variables of the morphological system, we used the Pearson correlation coefficient. In addition, we calculated the dimorphism index for the biacromial and bicristal range as the point of the biserial correlation between the peripheral types of sport and every horizontal axis. It has been determined that in the case of handball players, it is possible to talk of biacromial and bicristal variants of an ectomesomorphic body type, while in the case of soccer players, of a biacromial variant of an ectomorphic type and a bicristal variant of an endomesomorphic body type. Both in the case of the biacromial and bicristal range, the dimorphism is pronounced among athletes who belong to different populations. 

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.

In clinical hyperkalemia, correlation between plasma K and the ECG is less reliable. A tall, peaked, symmetrical T wave with a narrow base, the so-called "tented" T wave is the earlinest ECG abnormality, usually best seen in leads II, III, V2, V3, and V4. The tented appearance and the narrow base are probably more characteristic of hyperkalemia than is the amplitude of the T wave. A decrease in amplitude of the R wave, appearance of a prominent S wave, widening of the QRS complex, depression of the ST segment evolve as plasma K approaches 8-9m Eq/liter. With hyperkaliemia, depression of intraventricular conduction is characteristically diffuse and results in prolongation of both the initial and terminal parts of the QRS complex. The resulting pattern may resemble RBBB, LBBB, left anterior or posterior divisional block, or a combination of the four.

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.
