Abstract
BACKGROUND A xanthoma is a rare bone condition consisting of a predominant collection of lipid-rich, foamy histiocytes. The central xanthoma of the jaws is a unique benign tumor. CASE REPORT A 15-year-old Caucasian male has been presented to our department. He had radiological changes in the area of the left mandibular angle, with an area of diffuse osteolysis of 3.0 cm by 2.0 cm. Computed tomography reveals an area of diffuse osteolysis that starts from the distal root of the lower second molar and reaches the ascending process. A bone biopsy was performed, which revealed a benign proliferative process composed of histiocytic cells involving and infiltrating trabecular bone in a background of loose fibrous connective tissue devoid of any other significant inflammatory infiltrate. The size of the formation was 2.9 cm by 2.0 cm. Immunohistochemical staining for CD68 was strongly positive and negative for S-100 and CD1a. From routine blood tests, cholesterol, triglycerides, and blood sugar are within normal values, which excludes systemic metabolic disease. Subsequent to the surgical intervention, the patient underwent postoperative assessments at intervals of 14, 30, 60 days, and a year later, revealing the absence of any discernible complications during the aforementioned observation periods. CONCLUSION The diagnosis of primary xanthoma of the mandible is rare and can often be confused with other histiocytic lesions. A differential diagnosis should be made with nonossifying fibroma and Langerhans cell histiocytosis, as in our case. In these cases, immunohistochemistry with CD 68, S-100, and CD1a, as well as blood parameters, are crucial for the diagnosis.

Abstract
Abstract
Background and purpose
Treatment effects from the large cardiovascular outcome trials (CVOTs) in diabetes are almost exclusively communicated as hazard ratios, although reporting guidelines recommend to report treatment effects also on an absolute scale, e.g. as numbers needed to treat (NNT). We aimed to analyze NNT in CVOTs of novel oral antidiabetic drugs comparing dipeptidyl peptidase-4 (DPP-4) inhibitors, glucagon-like peptide-1 (GLP-1) receptor agonists, or sodium-glucose cotransporter-2 (SGLT2) inhibitors to placebo.
Methods and results
We extracted individual time-to-event information for the primary outcome and all-cause mortality from 19 CVOTs that compared DPP-4 inhibitors, GLP-1 receptor agonists, or SGLT2 inhibitors to placebo. We estimated Weibull models for each trial and outcome and derived monthly NNTs. NNTs were summarized across all trials and within drug-classes by random effects meta-analysis methods. Treatment effects in the CVOTs appear smaller if they are reported as NNTs: Overall, 60 (95%-CI: 40–124) patients have to be treated for 29 months (the median follow-up time across all trials) to avoid a single event of the primary outcome, and 101 (95%-CI: 69–191) patients have to be treated for 39 months to avoid a single death.
Conclusion
We found that the respective treatment effects of novel oral antidiabetic drugs look less impressive when communicated on an absolute scale, as numbers needed to treat. For a valid overall picture of the benefit of these drugs, trial authors should thus also report treatment effects on an absolute scale.

Abstract
Common metabolic diseases such as obesity, type 2 diabetes mellitus and non-alcoholic fatty liver disease significantly contribute to morbidity and mortality worldwide. They frequently associate with insulin resistance and altered mitochondrial functionality. Insulin-responsive tissues can show changes in mitochondrial features such as oxidative capacity, mitochondrial content and turnover, which do not necessarily reflect abnormalities but rather adaption to a certain metabolic condition. Lifestyle modifications and classic or novel drugs can modify these alterations and help treating these metabolic diseases. This review addresses the role of mitochondria in human metabolic diseases and discusses potential future research directions.

Abstract
BACKGROUND Recently, there has been an interest in the relative effectiveness of progressive muscle relaxation (PMR) within the multidisciplinary treatment of patients with schizophrenia.The present study is aimed at providing evidence on the efficacy of PMR as means of alleviating the state anxiety and psychological distress and a way to increase subjective well-being in chronic patients with schizophrenia. SUBJECTS AND METHODS Sixty four schizophrenia patients underwent 2 sessions of PMR. On the third session they were randomly allocated to either the PMR or the reading control condition. The State Anxiety Inventory (SAI) was used to assess state anxiety and the Subjective Exercise Experience Scale (SEES) to assess psychological distress and subjective well-being before and after the third session for both groups. RESULTS Our data show a significant time by group interaction for the SAI and SEES (Wilks λ=0.58, p<0.001). Effect sizes for PMR were -0.22 (95%CI=-0.73 to 0.19) for state anxiety, -0.96 (95%CI=-0.41 to -1.43) for psychological stress, and +1.01 (95%CI=0.45 to 1.54) for subjective well-being. CONCLUSION The present study provides scientific evidence for the utility of PMR in the chronic psychiatric settings for patients with schizophrenia.

Abstract
UNLABELLED The aim of this paper is to present the importance of orthopaedics in the prevention, treatment and rehabilitation of persons with cerebral palsy. MATERIAL AND METHODS The paper is based on a study realized at the University Orthopaedic Clinic, Medical School, Ss. Cyril and Methodius University in Skopje, with application of documentary analysis, observation and clinical analysis of 76 patients with cerebral palsy, aged between 1 and 15 years. RESULTS Orthopaedics is a surgical field of medicine, in which context there have been, are and will be, as a challenge, many questions for the present and future generations. Data analysis pointed out that surgical treatment in combination with conservative treatment give a hope that a definite or prolonged cure is possible, with maximal and possibly preserved function of the loco-motor system or, in the most serious cases, abatement of the impaired locomotor system symptoms. SUMMARY Early diagnosis and appropriate application of surgical treatment enable better functioning of persons with cerebral palsy by maximal exploitation of their remaining abilities.

Abstract
We report our clinical opinion for recombinant activated factor VII (NovoSeven, Novo Nordisk, Copenhagen, Denmark) administration in gynecology patients with massive haemorrhage. 3 women with gynecology deseases and severe bleeding in recieved NovoSeven in bolus IV. The blood loss and laboratory changes in hematology and haemostasis parameters are monitored. The bleeding was ceased in all cases. Decrease in values of Hb, Er and PTT was noted. The use of recombinant factor VIIA in gynecology patients with severe bleeding is effective and safe enough and could be an alternative to the extreme surgical procedures.

Abstract
138 patients with chronic papillooditis were investigated, 15 of them in a stage of decompensation. In 83.3% of the cases, the diagnosis was not clinically determined (including 68 of 92 endoscoped before their hospitalization--82.9%). 34 patients were diagnosed as having chronic gastroduodenitis, 15--ulcer, 42--chronic cholecystitis, 11--chronic pancreatitis, 4--cholangitis, 9--postcholecystectomic status. All these diseases developed simultaneously with the papillitis. In a second endoscopic check-up with an examination of papilla Vateri, the patients were in all the cases diagnosed without difficulties and the diagnose was confirmed by biopsy. In 21 patients there was confirmed primary papillooditis and in 127--accompanying disorders: chr. gastroduodenitis--29, chr. atrophic gastritis--18, ulcer--15, chr. cholecystitis--42, postcholecystectomic status--9, choledocholithiasis--14, chr. pancreatitis--11. Most often misdiagnosis occurs if: 1) during the routine endoscopic investigation the endoscopist does not examine papilla of Vater; 2) chr. papillitis exists simultaneously with one of the already mentioned diseases that are easier of approach for diagnostics and explanation of the disorders; 3) the clinical picture of papillitis cannot be differentiated from the one of the basic or accompanying disease; 4) the bile drainage is not prevented; 5) the result of the venous biligraphy does not lead to the diagnosis and ERCP is carried out only in a case of a clinical suspicion.

Abstract
The study covers 39,233 patients presenting biliodigestive pathology of which 12,230 in advanced and senile age, admitted to the emergency surgery section of the EMI "NI Pirogov" over a 12-year period (1985 through 1996). Of the total number, 6555 or 53.71 per cent are subjected to operation, with postoperative deaths amounting to 477 (7.27 per cent). In 320 cases (4.88 per cent) 218 men and 102 women, relaparotomy is done for postoperative peritonitis with 55 per cent lethality. Postoperative peritonitis is usually observed after operative treatment of ulcers. Operations for bleeding ulcers are performed in 175 patients of which 32 (18.28 per cent) are relaparotomized. Those operated for postoperative peritonitis are 65 per cent with 21 fatal outcomes; the commonest cause of death is insufficiency of the anastomosis or duodenal stump, followed by subhepatic and interfold abscesses.

Abstract
The effect of medazepam in a model of isolation aggression in mice was studied according to Yen et al. It was established that the mean effective dose of medazepam was 250 micrograms/kg and the therapeutic index (LD50:ED50) 6200. The simultaneous biochemical investigations showed a reduction of the affinity and number of benzodiazepine receptors in the brain of aggressive animals. Medazepam 10 mg/kg p.o. led to the restoration of the number of benzodiazepine receptors at a single and 10-day treatment.
