Abstract
This study aimed to assess the prognostic significance of total leukocyte count (TLC) and hemoglobin (Hb) levels upon admission for patients with acute pulmonary embolism (PE), considering the European Society of Cardiology (ESC) model for mortality risk. 1622 patients from a regional PE registry were included. Decision tree statistics were employed to evaluate the prognostic value of TLC and Hb, both independently and in conjunction with the ESC model. The results indicated all-cause and PE-related in-hospital mortality rates of 10.7% and 6.5%, respectively. Subgrouping patients based on TLC cut-off values (≤11.2, 11.2-16.84, >16.84 × 109/L) revealed increasing all-cause mortality risks (7.0%, 11.8%, 30.2%). Incorporating Hb levels (≤126 g/L or above) further stratified the lowest risk group into two strata with all-cause mortality rates of 10.1% and 4.7%. Similar trends were observed for PE-related mortality. Notably, TLC improved risk assessment for intermediate-high-risk patients within the ESC model, while Hb levels enhanced mortality risk stratification for lower-risk PE patients in the ESC model for all-cause mortality. In conclusion, TLC and Hb levels upon admission can refine the ESC model's mortality risk classification for patients with acute PE, providing valuable insights for improved patient management.

Abstract
OBJECTIVE Lung cancer (LC) is one of the most frequently diagnosed cancers and the leading cause of cancer mortality worldwide. The aim of this study was to get a comprehensive insight into the epidemiology of LC among patients in Vojvodina, the Northern Serbian region, during the ten-year period. PATIENTS AND METHODS This retrospective study was performed using LC hospital registry data of the Institute for Pulmonary Diseases of Vojvodina (IPBV) from 2011 to 2020. All patients reported in the registry with a place of residence in Vojvodina were included in this study. The data used in this research were: date of diagnosis, gender, age at diagnosis, place of residence, smoking habits at diagnosis, the intensity of smoking (pack/years), ECOG performance (0-5), histological cancer type, TNM classification and disease stage. RESULTS A total of 12,055 LC patients were included, 69.6% of whom were male. The percentage of female LC patients significantly increased, from 26.9% in 2011 to 35.9% in 2020 (p<0.001). Non-small cell lung cancer (NSCLC) was diagnosed in 80.8% of patients, while 15.4% of patients had small cell lung cancer (SCLC). The most common histological type was adenocarcinoma (41.9%), followed by squamous cell carcinoma (30.0%) and SCLC (15.4%). CONCLUSIONS The number of diagnosed LC patients in the Northern Serbian region increased over the past decade and is significantly higher in females. There was a strong correlation between smoking habits and LC in both genders. Our results also indicate the importance of introducing and promoting LC screening programs for all risk populations, particularly current and ex-smokers of younger age.

Abstract
Introduction/Objective. Tonsillitis is a very common condition found in the pediatric population but also in adult patients. One of the consequences of such conditions is poor voice quality. Hoarseness, poor voice impostation, interruption, and hypernazalization are just some of the differences in patient voice quality. The objective of this paper was to examine the effects of tonsillectomy on the voice quality. Methods. The sample included 37 patients, 17 female and 20 male, ranging in age 3?39 years. The method involved recording patients one month before and one month after tonsillectomy with a digital sound recorder, with recordings analyzed in the Praat program. The variables monitored in the basic voice were as follows: voice pitch, standard deviation of voice, degree of voice interruption, jitter, shimmer, and signal-to-noise ratio. In the statistical analysis, in addition to standard descriptive analyzes, t-test and ACNOVA were also used. Results. The results showed that there are effects of tonsillectomy on standard deviation of baseline voice (p = 0.002), shimmer (p = 0.002), baseline voice interruption rate (p = 0.023), signal to noise ratio (p = 0.003). There were no differences in the effects of tonsillectomy with respect to the sex of the subjects. Conclusion. Based on the conducted research, there were some methodological conclusions that could be considered as a recommendation for future research: increase the number of persons in the sample, introduce a variable of chronological age, type of surgical intervention, and gradation of size of the tonsil and adenoid tissue.

Abstract
SummaryBeneficial effects of aggressive lipid-lowering with high-dose atorvastatin (80 mg/day) have been demonstrated in patients with coronary and cerebrovascular disease. The impact of such a therapy in patients with peripheral arterial disease (PAD) is less known so far. Here we studied the effects of high-dose atorvastatin on brachial artery endothelial function, common carotid intima-media thickness (IMT) and local progression of PAD in these patients. One hundred of 500 patients screened with documented PAD were randomly assigned to receive 80 mg of atorvastatin daily for six months or to continue on conventional medical treatment. Ninety-six percent of patients in the control group were on standard statin treatment. High resolution B-mode ultrasonography was used to study brachial artery flowmediated dilation (FMD), IMT and ankle-brachial index (ABI) at baseline and at six months. FMD and IMT at baseline and at six months were 4.1 (0.06–8.6) versus 5.0 (0.76 vs. 8.1) %, p=0.96, and 0.76 (0.66–0.82) versus 0.73 (0.63–0.81) mm, p=0.41, respectively, in the atorvastatin group, and 2.66 (-1.9 – 6.9) versus 3.65 (0.0–8.6)%, p=0.02, and 0.78 (0.71–0.90) versus 0.77 (0.70–0.90) mm, p=0.48,in the control group. ABI at baseline and at six months was not different in either group. LDL cholesterol was reduced from 2.53 (2.21–3.28) to 1.86 (1.38–2.29) mM (p<0.0001) in the atorvastatin group, whereas levels remained stable in the control group [2.38 (1.94–3.16) vs.2.33 (1.82–2.84) mM, p=0.61]. Major adverse cardiovascular events occurred in 2.1% in the atorvastatin group and 1.9% in the control group (p= 0.61). In conclusion, in this pilot trial aggressive lipid-lowering with 80 mg of atorvastatin daily for six months had no effect on brachial artery FMD in patients with PAD. IMT andABI were also similar in patients with and without high-dose atorvastatin at six months.

Abstract
Background Riedel thyroiditis is a rare, chronic inflammatory disease of the thyroid, characterized by a dense fibrosis that replaces normal thyroid parenchyma. In literature descriptions of individual cases of Riedel thyroiditis can be found. Case report We present an euthyroid patient with multinodular goiter who was diagnosed with Riedel thyroiditis using pathology. Imaging diagnostic methods (Ultrasonography, X-ray computed tomography, Magnetic resonance imaging, Radionuclide imaging) or various tests of thyroid function cannot confirm the diagnosis of Riedel thyroiditis. Conclusion Only level of IgG4 may be helpful for the diagnosis of Riedel thyroiditis, while pathology is used for its definitive confirmation.

Abstract
Neodymium yttrium-aluminium-garnet (Nd : YAG) laser resection is one of the mostly used interventional pulmonology techniques for urgent desobstruction of malignant central airway obstruction (CAO). The major aim of this trial was to evaluate potential influence of Nd : YAG laser resection on overall quality of life (QoL) in patients with central lung cancer. Patients with malignant CAO scheduled for Nd : YAG laser resection were prospectively recruited in the trial. All patients were given European Organization for Research and Treatment, Quality of Life questionnaire (EORTC QLQ-30 v.3) before the procedure and approximately 2 weeks after the treatment. There were 37 male and 10 female patients, average age 54 ± 10 years. Most common tumour type was adenocarcinoma diagnosed in 51% of patients. Majority of patients were diagnosed in stage IIIB (53.2%) and stage IV (25.5%). Most common Eastern Cooperative Oncology Group performance status was 1 (72.3%). Nd : YAG laser resection significantly improved (P<0.0001) QoL and overall health according to EORTC QLQ-30. However, in some of the questions dealing with nausea, vomiting, diarrhoea, constipation, family life, social activities and financial situation, we did not observe statistically significant improvement. Nd : YAG laser resection of malignant CAO significantly improves QoL and overall health in patients with lung cancer.

Abstract
The purpose of this study was to investigate lymphatic clearance of the human skin in patients with acute deep thrombosis of the femoral vein. In 13 patients with deep vein thrombosis and no other cause for swelling of the limbs, lymphatic clearance of the skin at the foot was measured. Ten microliters of fluorescein isothiocyanatedextran 150,000 were injected intradermally and the fluorescent light intensity of the deposit measured 10 min and 24 hours after injection by window densitometry. In addition, intralymphatic pressure was measured by the servo-nulling system. The results were compared with a sex- and age-matched control group. Fluorescent light intensity decreased by 23.8 +/- 12.3 arbitrary units or by a factor of 1.8 +/- 0.5 in patients with DVT after 24 hours, which was significantly less than in healthy controls (33.7 +/- 8.9 arbitrary units or by factor 5.0 +/- 4.1, p < 0.013). Intralymphatic pressure was not different between the two groups. These results indicate that lymphatic clearance is significantly reduced in the acute phase of deep venous thrombosis.

Abstract
Rheological abnormalities are well known in patients with peripheral arterial occlusive disease (PAOD). We wanted to determine whether rheological variables are related to restenosis after femoropopliteal percutaneous transluminal angioplasty (PTA). In 114 patients (62 men; median age 70 years) undergoing femoropopliteal PTA for symptomatic peripheral arterial occlusive disease (PAOD) plasma viscosity, red cell aggregation, whole blood viscosity, hematocrit, fibrinogen, platelet count, leukocytes and C-reactive protein were determined the day after the procedure and at 1, 3, and 12 months. The primary endpoint was restenosis >50% documented by duplexsonography up to 12 months. Cox proportional hazards analysis was used to assess the risk of restenosis for postinterventional values of rheological variables. Forty-eight patients (42%) developed restenosis at 12 months. Patients with restenosis had higher baseline plasma viscosity (PV) (medians, 1.71 vs. 1.65 millipascal seconds [mPa.s]; p = 0.04) and lower platelet count (224 vs. 240 x 10(3)/microl; p = 0.03) than patients without restenosis. The hazard ratio (HR; 95% CI) of incident restenosis was 9.2 (1.12-76; p = 0.03) for PV and 0.99 (0.99-1.0; p = 0.07) for PLT. When examining jointly both high PV and low platelet count (PLT), patients with PV > 1.66 mPa.s and PLT < 233 x 10(3)/microl (i.e. variables split at their respective median) had an increased risk of restenosis (log-rank test p = 0.01). Multivariate Cox proportional hazard analysis showed that plasma viscosity (p = 0.02), low platelet count (p = 0.01), lesion length (p = 0.0037) and lack of hypertension (p = 0.01) were associated with restenosis at 12 months. No associations were found between restenosis and the other rheological and inflammatory variables studied. Our data suggest that increased PV and low PLT contribute to restenosis after femoropopliteal PTA.

Abstract
PURPOSE To assess the relationship between plasma homocysteine levels and restenosis after femoropopliteal percutaneous transluminal angioplasty. METHODS Over a 10-month period, 128 consecutive, symptomatic patients (72 men; median age 70 years) having successful femoropopliteal angioplasty for atherosclerotic occlusive disease were prospectively enrolled in the study. Plasma homocysteine levels were determined the day before the procedure. The primary endpoint was restenosis >50%, documented by duplex sonography, at up to 12 months' follow-up. Cox proportional hazards analysis was used to determine the risk of restenosis in relation to pretreatment homocysteine levels. RESULTS The restenosis rate at 12 months was 46%. Median baseline plasma homocysteine levels were not different in patients with and without restenosis (15.4 versus 16.7 micromol/L, p=0.30). Compared to patients with homocysteine levels </=14 micromol/L (lower tertile, n=43), the hazard ratio of incident restenosis was 0.75 (95% CI 0.40 to 1.40) in patients with homocysteine levels from 14.1 to 19.6 micromol/L (middle tertile, n=42) and 0.64 (95% CI 0.33 to 1.22) in patients with homocysteine levels >/=19.7 micromol/L (upper tertile, n=42) (p=0.38). Multivariate analysis showed that lesion length (p<0.0001) and lack of hypertension (p=0.0013) were associated with restenosis. CONCLUSIONS Elevated plasma homocysteine levels are not associated with restenosis after femoropopliteal angioplasty. Therefore, plasma homocysteine cannot be considered as an important risk factor influencing the outcome after initially successful angioplasty in femoropopliteal arteries.
