Introduction/Objective. Low-level laser therapy has been suggested as an alternative pain relief therapy in temporomandibular disorder patients. The aim of this study was to examine the effects of low-level laser therapy on reducing pain intensity in temporomandibular disorder patients, compared to nonsteroidal anti-inflammatory drugs. Methods. A total of 63 patients diagnosed with Research Diagnostic Criteria for Temporomandibular Disorders were divided into two groups. In the first group of 35 patients, low-level laser therapy was applied three times a week, 15 treatment sessions during five weeks (wavelength: 780 nm; power density: 70 mW/ cm2; radiant energy: 4.2 J; energy density: 4.2 J/cm2; total treatment dose: 16.8 J/cm2). The second group included 28 participants subjected to nonsteroidal anti-inflammatory drugs therapy (ibuprofen) during two weeks (first three days 3 × 400 mg, remaining time 2 × 400 mg per day). Pain was evaluated using 100 mm visual analog scale, at the baseline, during therapy, two weeks and three months after treatments. Results. Statistically significant reduction of pain intensity was achieved in both low-level laser therapy and in nonsteroidal anti-inflammatory drugs therapy groups and remained steady in the follow-up period of three months (p < 0.01). Differences in visual analog scale scores between the observed groups were not statistically significant in each of the evaluation periods, (p = 0.375, p = 0.665, p = 0.52, respectively). Conclusion. The low-level laser therapy protocol applied in this research was efficient in reducing pain in patients with temporomandibular disorders.

The aim of the paper was to present the results achieved with triple pelvic osteotomy in the treatment of residual hip dysplasia, with special interest in identifying recurrences and complications and how to avoid them. 60 patients (76 hips) with developmental dysplasia of the hip (DDH), treated by the triple pelvic osteotomy according to Tönnis and modified by Vladimirov, were included in the study. Hips were evaluated radiologically with the center-edge (CE) angle, break of the Shenton-Menard arch and index of acetabular depth by Heyman-Herndon, and functionally using the Harris Hip Score (HHS). The postoperative results showed an average increase of the CE angle by a mean of 23.5±9.28 degrees, with a highly significant difference between the preoperative and final postoperative findings (t-test, t=-20.85, p<0.01). The mean HHS significantly improved (p<0.01). Total complication rate was 13,1%, divided in: 1,3% (one case) of triple nonunion of iliac, pubic and ischial bones, 7,9% (six cases) of double nonunion of pubic and ischial bones, 2,6% (two cases) of peroneal palsy and 1,3% (one case) of infection. In this study the triple pelvic osteotomy showed to be reliable for acetabular dysplasia in adolescent and young adult, alone or in association with proximal femoral osteotomy and/ or great trochanter distal advancement.

Background/Aim. Matrix metalloproteinase-9 (MMP-9) index is the ratio of active MMP-9 and total MMP-9 levels. It reflects the importance of MMP-9 in acute coronary syndrome (ACS). Methods. The study included 3 groups of patients (n = 87): the group 1 - non-diabetic subjects without ACS (control); the group 2 - diabetic patients with ACS [subgroups with unstable angina pectoris (UAP), myocardial infarction (MI) or reinfarction]; and the group 3 non-diabetics patients with ACS. Total and active MMP-9 were measured and used to create MMP-9 index. Results. MMP-9 index, as a marker showed good sensitivity and specificity, of ACS in diabetics, with a cut-off value over 58.2. MMP-9 was higher in the study groups than in the control one. MMP-9 correlated with ACS occurrence and type of cardiovascular event. A statistically significant difference was found among the groups according to active MMP-9 (p < 0.001). The same was found with active MMP-9 between the control and the group with MI (p < 0.001). The control was highly statistically significantly different from the group of patients with UAP (p < 0.01). Statically significant differences in MMP-9 index was found between the control and the diabetics with ACS (p < 0.001). Statistically significant difference of MMP-9 index was also found in the controls compared to the value in non-diabetic patients with ACS (p < 0.01). Conclusion. MMP-9 index may be a possible marker of atheromatous plaque rupture in diabetics.

Introduction. Perthes disease is idiopathic avascular osteonecrosis of the hip in children, with unknown etiology. Inflammation is present during development of Perthes disease and it is known that this process influences bone remodeling. Objective. Since genetic studies related to inflammation have not been performed in Perthes disease so far, the aim of this study was to analyze the association of frequencies of genetic variants of immune response genes, toll-like receptor 4 (TLR4) and interleukin-6 (IL-6), with this disease. Methods. The study cohort consisted of 37 patients with Perthes disease and 50 healthy controls. Polymorphisms of well described inflammatory mediators: TLR4 (Asp299Gly, Thr399Ile) and IL-6 (G-174C, G- 597A) were determined by polymerase chain reaction restriction fragment length polymorphism method. Results. IL-6 G-174C and G-597A polymorphisms were in complete linkage disequilibrium. A statistically significant increase of heterozygote subjects for IL-6 G-174C/G-597A was found in controls in comparison to Perthes patient group (p=0.047, OR=2.49, 95% CI=1.00-6.21). Also, the patient group for IL-6 G-174C/G- 597A polymorphisms was not in Hardy-Weinberg equilibrium. No statistically significant differences were found between patient and control groups for TLR4 analyzed polymorphisms. A stratified analysis by the age at disease onset also did not reveal any significant difference for all analyzed polymorphisms. Conclusion. Our study revealed that heterozygote subjects for the IL-6 G-174C/G-597A polymorphisms were significantly overrepresented in the control group than in the Perthes patient group. Consequently, we concluded that children who are heterozygous for these polymorphisms have a lower chance of developing Perthes disease than carriers of both homozygote genotypes.

Introduction. Numerous authors have indicated the beneficial effect of glycoregulation on micro- and macro-angiopathic complications. Objective. The aim of the study was to examine whether intensive treatment with maintaining blood glucose concentrations close to normal range could improve electrophysiological parameters. Methods. The study involved 81 patients with type 1 diabetes mellitus type 1 randomly assigned to intensive insulin therapy. The patients were followed for a period of 3 months by metabolic and electrophysiological control. The metabolic control included daily measurement of concentration of blood glucose and HbA1c and lipid status, while the neurophysiological control included nerve conduction velocity (NCV) of median, peroneal, tibial and sural nerve and latency of F wave. Results. In the beginning of our study blood glucose was 9.10±3.69 mmol/l and HbA1c 8.12±1.20%. After 3 months of administered intensive insulin therapy, blood glucose was 7.88±2.79 mmol/l and HbA1c 6.63±1.33. After 3 months NCV improved in the tibial, median and sural nerve (p

Introduction The number of patents with dementia increases among hip fracture patients. Cognitive dysfunction is defined as a premorbid state which is potentionally negatively related to short-term functional outcome. Objective To assess the relationship between cognitive status on admission and functional gain during an early rehabilitation period in elderly hip fracture patients. Methods Forty-five elderly patients with surgically treated hip fracture were examined. Cognitive status was assessed by the Mini Mental State Examination (MMSE) at admission; functional status was assessed by the motor subscale of Functional Independence Measure (FIM) at admission and before discharge, while absolute functional gain was determined by the motor FIM gain (FIM discharge - FIM admission). Absolute functional gain was analyzed in respect to cognitive status. Results Both cognitively impaired and cognitively intact hip fracture patients exhibited overall FIM motor improvements, as well as functional gains in specific FIM motor areas (p0.05). Conclusion The systematic use of MMSE identifies cognitively impaired hip fracture patients, and effectively predicts their short-term functional outcome. A higher admission cognitive status is related to a more favorable short term rehabilitation outcome. In spite of cognitive impairment, elderly patients with hip fracture can benefit from participation in rehabilitation programmes. The systematic identification of cognitively impaired hip fracture patients at admission facilitates optimal treatment and rehabilitation, and thus enables the best achievable outcome to be reached.

Background/Aim. During the first 10 years over 50% of diabetes patients develop erectile dysfunction (ED). It is more severe and resistant to therapy than in male patients with normal glucoregulation. The purpose of this pilot study was to estimate the tadalafil (Cialis) efficacy and safety in male patients with diabetes mellitus (DM), together with moderate to severe ED. Methods. The study included 30 male patients with diagnozed type 1 or type 2 DM together with ED. ED was estimated through the International Index of Erectile Function (IIEF-6), Sexual Encounter Profile (SEP) questionnaire and prostaglandin test, at the beginning of the research and three months after the 20 mg tadalafil therapy initiation, once a week (on Fridays). Glycosylated haemoglobin in blood (HbA1c) values were also monitored. According to the ED severity (IIEF values at the beginning of the therapy) the patients were divided into 2 groups. The previous experience with sildenafil citrate (Viagra) and prostaglandin E1 intracavernous therapy was recorded. Results. Tadalafil significantly improved ED (p < 0.001) for 7.40 points of the IIEF score, i.e. for 58% and 60% towards SEP2 and SEP3 questionnaire, respectively. Compared to the previous ED therapy subjectively better tadalafil experience was recorded. Each group experienced a significant improvement in IIEF score (p < 0.001), more significantly in the group 2 (8.26±1.49 points) compared with the medium improvement in the group 1 (6.27±1.35 points). After three months HbA1c values decreased for 2.26±1.62 (p < 0.001). Conclusion. Tadalafil is an effective tool for treating ED in diabetes patients. In some situations tadalafil application could replace prostaglandin test. The sexual sphere motivation leads to the improvement of glucoregulation in DM patients. .

Introduction: Optimal treatment of ACL (anterior cruciate injury) injuries is one of the most dynamic topics of contemporary orthopedics. Despite huge amount of publications on this subject, golden rehabilitation standard has not been established yet. Objective: The aim of our study was to compare two different rehabilitation groups in respect to dynamics and safety of recovery, and accordingly to recommend contemporary rehabilitation approach. Method: A prospective study included 45 patients with unilateral ACL rupture who were randomized into conservative (THC) and intensive rehabilitation (TH-I) group. The arthroscopic reconstruction of ACL was performed using the BTBP or STG graft. After the operation, in the TH-C group, ROM was limited to 0-0-90˚ and weight bearing was not allowed in the first 4 postoperative weeks. In the TH-I group, progression depended only on the knee edema and pain. The groups were compared in relation to demographic, anamnestic, and clinical characteristics (knee circumference, thigh circumference, stability tests, Lysholm, Tegner and one-leg hop test, and single stance test). Data were recorded preoperatively and postoperatively after 6 weeks, 4, 6, 9 and 12 months, and compared with parametric and non-parametric statistical tests. Results: The investigated groups clearly differed already after 6 weeks by range of motion (p

Rehabilitation after ACL (anterior cruciate ligament) reconstruction has drastically changed over the last decade, with the adoption of a more aggressive approach, right from the first day after surgery. Progress in the effectiveness of rehabilitation is based on improvements in operative techniques, as well as on the encouraging results of histological studies regarding graft healing. Despite a huge amount of research papers on this topic, a rehabilitation golden standard still has not been established, due to the complexity of this problem. In this review, we point out the basic principles of rehabilitation after arthroscopically assisted ACL reconstruction based on actual practices, as well as the importance of specific procedures for the prevention of complications during the postoperative period. The importance of range-of-motion exercises, early weight bearing, an appropriate gait scheme, patella mobilisation, pain and oedema control, as well as stretching and balance exercises is explained. The functional advantages of closed kinetic chain exercises, as well as their influence on the graft are also described, in comparison to open kinetic chain exercises. The fundamentals of returning to sports are revealed and the specific aspects of rehabilitation regarding graft choice are pointed out. While waiting for new clinical investigations, which are expected to enable the establishment of a rehabilitation golden standard, the outlined principles should be followed. The complexity of this injury requires treatment in highly specialised institutions.

ACL injury leads to a decrease in proprioceptive abilities, which can be improved with ACL surgery and postoperative rehabilitation. The goal of our study was to investigate whether the impact of coordinative training can be differentiated from the influence of surgery on proprioceptive improvement, and whether there is a correlation between improvement in coordinative abilities and other objective parameters of functional recovery. This follow-up study included 45 patients who had undergone ACL reconstruction and who were randomized into a conservative (TH-C) and an intensive (TH-I) rehabilitation group. In the TH-I group, coordinative training began earlier due to unrestricted weight-bearing. The groups were first compared preoperatively, then postoperatively, after 6 weeks, 4,6,9, and 12 months via the single leg stance test, the one leg hop test, the Lysholm knee score, and the Tegner score. A faster recovery of coordinative skills was registered in the TH-I group. Already after 6 weeks, highly statistically significant progress in one leg stance abilities was noticed, while in the TH-C group the same was not noticed until 4 months after surgery (p

Boleslas Matuszewski, born in 1856, was a pioneer in medical film-making. He worked simultaneously on improving his movie camera, film-making, collecting film documentation, and the idea of establishing an archive of medical films. Although his first attempts at filming and showing surgical operations didn't gain widespread approval, he was not discouraged, and succeeded in garnering support from a number of French doctors, who realized the importance of his ideas, not only in filming and forming medical film documentation, but also in the use of film for educative purposes. His visionary ideas gained acceptance when Dr. Doyen, on the occasion of the 66th Convention of the British Medical Society, in 1898, used film material as part of his lecture. Shortly afterwards, the Medical Academy took steps to show certain operative techniques, which represented both the confirmation and fruition of Matuszewski's ideas about filmmaking and the establishment of an archive of medical films.

Background: Aim of our study was to evaluate degree of genetic homozygosity in male and female gender of spina bifida (SB) occulta and SB aperta patients. Patients and Methods: We evaluated 95 patients with SB occulta and 51 with SB aperta. Degree of genetic homozygosity was evaluated by direct observation of 15 homozygously recessive characteristics (HRC) by HRC-test separately for SB occulta and SB aperta participants. Additionally 370 individuals without SB from Serbia were randomly selected and evaluated as control group. Male and female gender was separately evaluated for assessing degree of genetic homozygosity. Results: There was no significant difference in mean values of HRC between male and female gender in control group (male gender -3.9±1.2, female gender -4.0±1.4, z=0.39; p>0.05), SB occulta (male gender -4.1±1.5, female gender -4.7±1.4, z=1.87, p>0.05) and SB aperta patients (male gender -4.3±1.6, female gender -4.5±1.4, z=0.66, p>0.05), while there was significantly increased recessive homozygosity in female SB occulta group versus control female group (Females: SB occulta -4.7±1.4, Control group -4.0±1.4, z=3.16, p<0.01) and female SB aperta group versus control female group (Females: SB aperta -4.5±1.4, Control group -4.0±1.4, z=2.05, p<0.05). Conclusion: There is increased recessive homozygosity in tested female SB occulta and female SB aperta individuals versus SB male participants and significantly increased recessive homozygosity in female groups of SB patients versus control female group. These findings could lead to the possible assumption that different genes in different degree might be expressed in SB occulta and SB aperta patients.

The mental health of healthcare workers, especially the nursing staff in intensive care units, is crucial for the optimal functioning of healthcare systems during medical emergencies. This study implements a cross-sectional design to investigate the associations between nurses' personal characteristics, workplace challenges, and job satisfaction with the increased perception of tension, stress, and pressure at the workplace (TSPW) before and during the COVID-19 pandemic. In 2021, we surveyed 4210 nurses from 19 intensive healthcare facilities in the capital of Serbia, Belgrade, and, at that time, collected data about their perceived TSPW before and during the COVID-19 pandemic. Our study identified six predictors of the increase in TSPW, as perceived by nurses: their work in COVID-19 infectious zones (OR = 1.446), exhaustion due to work under protective equipment (OR = 1.413), uncertainty and fear of infection (OR = 1.481), a high degree of superiors' appreciation and respect (OR = 1.147), a high degree of patients' attitudes (OR = 1.111), and a low degree of work autonomy (OR = 0.889). The study's findings suggest that a solution to this issue is necessary to ensure that nurses are safe and able to alleviate the physical and mental strain that comes with prolonged use of protective equipment. Nurses on the frontline of the pandemic require better health protection, better conditions, and respect for their role. Strategies to promote mental health would help reduce nurses' stress and increase job satisfaction.

Background: The purpose of this study was to investigate which psychosocial risk factors show the strongest association with occurrence of myocardial infarction (MI) in the population of Belgrade in peacetime, after the big political changes in Serbia., Methods: A case-control study was conducted involving 154 consecutive newly diagnosed patients with MI, and 308 controls matched by gender, age, and place of residence., Results: According to conditional logistic regression analysis, after adjustment for conventional coronary risk factors, the odds ratios (95% confidence intervals) for work-related stressful events, financial stress, deaths and diseases, and general stress were 3.78 (1.83-7.81), 3.80 (1.96-7.38), 1.69 (1.03-2.78), and 3.54 (2.01-6.22), respectively. Among individual stressful life events, the following were independently related to MI: death of a close family member, 2.21 (1.01-4.84); death of a close friend, 42.20 (3.70-481.29); major financial problems, 8.94 (1.83-43.63); minor financial problems, 4.74 (2.02-11.14); changes in working hours, 4.99 (1.64-15.22); and changes in working conditions, 30.94 (5.43-176.31)., Conclusions: During this political transition period , stress at work, financial stress, and stress in general as they impacted the population of Belgrade, Serbia were strongly associated with occurence of MI.

The aim of our study was to investigate the relationship between the metabolic control parameters of diabetes mellitus (glycemia and HbA1c) and visual evoked potentials (VEP) latency values. The study included 61 patients with diabetes mellitus type 1 that were hospitalized at the Clinic for Endocrinology, Diabetes and Metabolic Diseases due to the poor metabolic control. All patients were divided into 3 groups. Group 1 consisted of patients on conventional insulin therapy (CT); Group 2 included patients on CT at the moment of hospitalization, with a change towards intensified insulin therapy (IIT); and Group 3 consisted of patients on IIT. Patients with diabetic retinopathy (DR) were excluded from the study. Metabolic control (glycemia and HbA1c) and VEP parameters were compared at the beginning of the study and six months later. After six months of strict glycoregulation, significant improvement in VEP parameters was followed by significant improvement of evaluated parameters of metabolic control. We found statistically significant reduction in frequency of pathological VEP findings, prolonged P100 latency and low amplitude potentials in Group 2, while in Groups 1 and 3 we found that these parameters did not significantly changed but the frequencies were lower. The VEP testing is a noninvasive diagnostic procedure which may help in early diagnosis of DR, prognosis during the metabolic control and treatment. If changes in the retina could be detected before DR is noticed using this noninvasive diagnostic procedure and include patients in a strict glycoregulation, we could be in the position to prevent serious complications that may cause blindness.

This article presents the results of Legg-Calve-Perthes (LCP) disease treatment using triple pelvic osteotomy. Thirty patients were analysed. The conditions for inclusion in the study were complete medical documentation and follow-up until the disease was resolved. Postoperatively, no patients were immobilised. Rehabilitation was initiated early in all patients, and full weight bearing was allowed after ten weeks. With this method, an increase of the CE angle of 17.43 +/- 4.020 degrees was achieved. Containment was increased from an initial 6.67% to 53.33% of patients at the final check-up. Similar improvement was achieved by using Herring classification of the damage; preoperatively most hips belonged to group C, and postoperatively to group A. Postoperatively, functional results were also considerably improved. The authors recommend triple pelvic osteotomy as the method of choice in the treatment of severe cases of LCP disease.
