Abstract Objectives Hereditary multiple exostosis (HME) often involves forearm deformities. The aim of this study was to present the clinical results of 37 children who underwent ulnar lengthening with two different types of unilateral external fixators and to investigate the risk factors of complications. Methods We evaluated 37 children with forearm deformities caused by HME treated in our hospital from January 2008 to July 2019. The surgical procedures included resection of exostosis, osteotomy of the ulna, and gradual lengthening of the ulna with a unilateral external fixator. According to the type of fixator they received, the children were divided into two groups: group A received monorail fixators and group B received multi-joint fixators. Radiographic and functional parameters were assessed. Complications were recorded. Results All patients were followed-up for an average of 4.6 years (3.0 to 6.5). In both group A and group B, the ulna shortening (US), radial articular angle (RAA), carpal slip (CS), elbow flexion, forearm pronation, supination, and Mayo Elbow Performance Score (MEPS) values improved significantly from preoperatively to postoperatively (p < 0.05). However, the ulnar deviation was observed in 4 cases in group B and no cases in group A. According to logistic regression, the difference was only related to age (p < 0.05) and the type of external fixator (p < 0.05). Conclusions Ulnar lengthening with unilateral external fixation is a safe and effective procedure for the treatment of HME. Regarding complications, deviation of the ulna axis was more likely to occur in older children with multi-joint external fixators.

Methods: We evaluated 37 children with forearm deformities caused by HME treated in our hospital from January 2008 to July 2019. The surgical procedures included resection of exostosis, osteotomy of the ulna, and gradual lengthening of the ulna with a single arm external fixator. According to the type of external fixator they received, the children were divided into two groups: group A received monorail fixators, and group B received multi-joint fixators. Radiographic and functional parameters were assessed. Complications were recorded. Results: All patients were followed up for an average of 4.6 years (3.0 to 6.5).

Modern trends in the deterioration of health and the growth of non-communicable diseases among the adult working-age population, including medical workers, actualize the importance of a healthy lifestyle for maintaining health and professional longevity. There were almost no studies related to cosmetologists' experienced group as representatives of aesthetic medicine. There is no scientific evidence on behavioral risks of this group. It justifies the relevance of this study. The study aims to analyze the essential components of the cosmetologists' lifestyle depending on age and the argumentation of priority behavioral health risk factors for preventive and recreational work justification. Sixty women (practicing cosmetologists in Volgograd at the age of 28-39 years (group A) and 40-53 (group B)) took part in the study. Lifestyle assessment included a modified questionnaire. The questionnaire consists of 5 blocks (block 1 - nutrition; 2 - physical activity, including hardening and active rest; 3 - daily regimen; 4 - personal hygiene; 5 - bad habits). It allows the analysis of the adherence to a healthy lifestyle based on the provision of quantitative data. Statistical data processing was carried out using the Excel package. The authors identified the essential and statistically significant differences in the cosmetologists' lifestyle depending on age. The respondents of group B demonstrated hygienically rational indicators in all blocks of the lifestyle more often. They had a more formed adherence to a healthy lifestyle: 504 answers in the category "insignificant risk" of respondents in group B versus 354 in group A. Distribution of answers in the "high risk" category: 119 responses in group B and 185 in group A. The lifestyle of 46.7% of the respondents in group B refers to a healthy lifestyle. 3.3% of the group B respondents have an anxious lifestyle, 50% have health risks. 10% of Group A respondents' lifestyle refers to a healthy lifestyle. 13.3% of Group A respondents' lifestyle refers to an anxious lifestyle; 76.7% of this group have health risks. There was almost no complex hygienic research profession of medical cosmetologists. Cosmetologists of the older age group (40-53 years old) are more conscious of maintaining a hygienically rational lifestyle. The most significant defects among cosmetologists aged 28-39 years are low physical activity, nutritional defects, insufficient duration of night rest, and excessive use of information and communication technologies for rest, accompanied by manifestations of neurotization and signs of pronounced fatigue. The obtained results argue the need to develop and implement informational and educational measures to prevent risk behavior patterns, taking into account the age of cosmetologists and the priority of the identified behavioral risk factors.

Background: Despite that the unfavorable prognostic role of a high Total Metabolic Tumor Volume (TMTV) in Follicular Lymphoma has been demonstrated, the role of SUVmax alone at baseline PET/CT could have a different prognostic role. Patients and Methods: We performed a retrospective observational monocentric cohort study. All patients affected by FL who underwent a basal PET/CT were included. Two subgroups were identified and compared in terms of PFS and OS: (A) Basal SUVmax ≤ 6; and (B) Basal SUVmax > 6. Results: Ninety-four patients were included, 34 in group A (36.2%) and 60 in group B (63.8%). The PFS at two years was comparable in the two groups (97%). The five-year PFS was 73.5% for group A and 95% for group B (p 0.005). The five-year PFS in the whole cohort was 87.5%. A clear advantage was confirmed in group A in the absence of other risk factors. Patients with SUVmax ≤ 6 and no risk factors showed a 5-year PFS of 73% against 83% for patients with SUVmax > 6 and at least two risk factors. Conclusion: A high FDG uptake favorably correlated with PFS. A low basal SUVmax reflected a higher rate of late relapse requiring a prolonged follow-up. The basal SUVmax is an approachable parameter with prognostic implications.

Atherosclerosis is significant risk factor for cardiovascular morbidity and mortality in dialysis patients. Aim of the study was ultrasound evaluation of intima media thickness on carotid arteries (as a marker of atherosclerosis), in dialysis patients and its correlation with proposed risk factors. Intima media thickness was measured in 45 dialysis patients with no signs of cardiovascular diseases (15 on peritoneal dialysis, group I,30 on hemodialysis, group II) and 20 healthy controls. The mean carotid artery intima media thickness was significantly higher in dialysis patients than in control group. According to intima media thickness, dialysis patients were divided in group A (patient with intima media thickness less or equal 0,720 mm) and group B (intima media thickness higher then 0,720mm). Intima media thickness in bout group was correlated with proposed risk factors. In group A there was not significant correlation of intima media thickness with risk factors. In group B significant correlation have been found between intima media thickness and LDL, VLDL cholesterol, body mass index and systolic, diastolic and mean blood pressure. Although atherosclerosis was not the only cause for cardiovascular morbidity and mortality, it has a dominant role in dialysis patients. Augmented intima media thickness could be early marker of atherosclerosis. The risk factors of great influence on intima media thickness are lipid disturbances, obesity and hypertension.

Abstract Background: A retrospective study investigated and compared the results of a lamina withspinous process (LSP) and an iliac graft (IG) as bone grafts in single-segment lumbar pyogenic discitis (LPD) through one-stage-posterior-only approach with radical debridement and internal instrumentation.Methods: Data from 37 patients were reviewed. A LSP was placed in 17 patients (group A), and an IG was implemented in 20 patients (group B). The surgery time, surgery hemorrhage, hospital stay, drainage, and follow-up (FU) were reviewed. The visual analogue scale (VAS), Oswestry Disability Index (ODI), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) level, segmental angle, intervertebral height and bony fusion time were compared preoperatively and at the final FU.Results: All patients were followed-up for a mean of 27.94±2.35 months in group A and 30.29±1.89 months in group B, without a difference. The mean age was younger in group A than in group B (P<0.05). The surgery time, surgery hemorrhage, and hospitalization cost were lower in group A than in group B (P<0.05), except for the hospital stay and drainage time. Fever occurred in 10 patients in group A and 12 patients in group B. The ESR, CRP level, and VAS and ODI scores were significantly decreased, and there were no significant differences between the groups at the final FU. The distribution of bacterial agents in blood culture was 1 case of Aerobacter cloacae, 2 of Staphylococcus aureus, 2 of Escherichia coli, and 1 of Streptococcus viridis in group A and 1 of S. aureus，1 of Staphylococcus warneri and 2 of Klebsiella pneumoniae in group B. Pyogenic infection was observed in the pathological findings of all patients. No significant difference was found in the mean segmental angle or mean intervertebral height preoperation and at the final FU between the groups.Conclusion: The use of LSP as a new bone graft is reliable, safe, and effective for surgical management for the LPD while surgery is proposed as a good management strategy for LPD in carefully selected patients.

ABSTRACT Objective: To evaluate and compare the knowledge of dental undergraduate students about oral cancer. Methods: The students were divided into two groups according to semester attended in the undergraduate course: Group A, the first semester; and Group B, seventh semester. They were asked to answer a questionnaire about epidemiology, risk factors, clinical aspects, therapeutic solutions and oral self-examination. For statistical analysis, the Fisher's exact test, the Cochran's G test and Kendall's concordance test were used, with significance level set at 0.05. Results: Regarding the prevalent sex, only 8.0% of Group A and 56.0% of Group B judged males as the frequent affected by the disease (p=0.0006). In terms of age, 84.0% of the Group B and 44.0% of the Group A estimated that most cases were diagnosed over 40 years (p=0.0072). Smoking was identified as the major risk factor for 64.0% and 91.6% of Groups A and B, respectively (p=0.0110). On issues related to sex, ethnicity, age, risk factors, self-examination, treatment, professional responsible for treatment and profile of an individual with the disease, the seventh-semester showed significantly higher correct answer percentages than first-semester undergraduates. Conclusion: There was significant correlation between the right and wrong answers given by first and seventh semester students, making necessary a specific approach directed to their lack of knowledge.

Background: Venoarterial extracorporeal membrane oxygenation support is a well-established tool in the care of severe refractory cardiac and respiratory failure. The application of this support may serve as a bridge to transplant, recovery or to implantation of a ventricular assist device. Venoarterial extracorporeal membrane oxygenation support can be administered through an open surgical access via the common femoral or axillary artery or a percutaneous approach using Seldinger technique. Both techniques may obstruct the blood flow to the lower limb and may cause a significant ischemia with possible limb loss. Malperfusion of the distal limb can be avoided using an ipsilateral distal limb perfusion, which may be established by adding a single-lumen catheter during venoarterial extracorporeal membrane oxygenation treatment to overcome the obstruction. The aim of this study is to distinguish the presence or absence of a distal limb perfusion regarding the incidence of distal limb ischemia. Furthermore, expected risk factors of open and percutaneous femoral venoarterial extracorporeal membrane oxygenation installation were evaluated for the development of distal limb ischemia. Methods: Between January 2012 and September 2015, 489 patients received venoarterial extracorporeal membrane oxygenation support at our institution. In total, 307 patients (204 male, 103 female) with femoral cannulation were included in the analysis. The cohort was distinguished by the presence (group A; n = 237) or absence (group B; n = 70) of a distal limb perfusion during peripheral venoarterial extracorporeal membrane oxygenation treatment. Furthermore, a risk factor analysis for the development of distal limb ischemia was performed. Results: The main indications for venoarterial extracorporeal membrane oxygenation therapy were a low cardiac output syndrome (LCOS) (53%) and failed weaning of extracorporeal circulation (23%). A total of 23 patients (7.49%) under venoarterial extracorporeal membrane oxygenation support developed severe distal limb malperfusion (3.38% in group A vs 21.42% in group B). Preemptive installation of distal limb perfusion extended the intervention-free intervals to 7.8 ± 19.3 days in group A and 6.3 ± 12.5 in group B. A missing distal limb perfusion (p = 0.001) was identified as a main risk factor for critical limb ischemia. Other comorbidities such as arterial occlusion disease (p = 0.738) were not statistically significantly associated. Surgical intervention due to vascular complications after extracorporeal membrane oxygenation explantation was needed in 14 cases (4.22% in group A and 5.71% in group B). Conclusion: We were able to identify the absence of distal limb perfusion as an independent risk factor for the development of critical distal limb ischemia during femoral venoarterial extracorporeal membrane oxygenation treatment. The application of a distal limb perfusion should be considered as a mandatory approach in the context of femoral venoarterial extracorporeal membrane oxygenation treatment regardless of the implantation technique.

Background: It has been postulated that adhesion molecules (AM) may be involved in development and progression of human atherosclerosis. We examined whether prostaglandin (PG) E1 affects circulating levels of the AM (ICAM-1, VCAM-1 and E-selectin) in peripheral vascular disease (PVD) patients. Methods and results: AM are significantly (p < 0.01) increased in PVD (n = 65) as compared to controls (n = 31). There was no influence of risk factors. 26 PVD-patients received 2 different schemes of PGE1-therapy (group A [n = 17]; 5 ng PGE1/kg/min × 6 h × 5 d × 4 wk; group B [n = 9]; 60 mug PGE1/2 h × 5 d × 2 wk). PGE1 decreases all the AM significantly (p < 0.01) using both therapeutic schemes. Stopping PGE1-therapy reverses values within about 4 weeks. Details on therapeutic regimens (dose, duration, route, etc.) and individual response still need to be assessed. Conclusion: Our results indicate that PGE1-treatment of PVD is associated with a significant benefit on circulating AM. These findings are in line with the described anti-inflammatory actions of PGE1 and may represent a further contributing factor to the great variety of beneficial actions of PGE1 on human atherosclerosis.

ABSTRACT Objective: To study the correlation of compound muscle action potential of donor nerves with the recovery of elbow flexion in Oberlin transfer in brachial plexus injury. Introduction: Distal nerve transfer using motor fascicle of ulnar or median nerve to restore elbow flexion is a part of reconstructive surgery after upper brachial plexus injury, first described by Oberlin et al. However, one of the most critical influences on functional outcome is number of functioning motor axons in donor fascicle which is reflected by its compound muscle action potential. We studied whether nerve transfers with donor nerves showing higher amplitudes will yield better reinnervation of muscle and therefore better function as estimated by clinical examination. Methods: We prospectively studied 30 cases of upper brachial plexus injury, of which were treated with Oberlin transfer using ulnar or median or both nerves. The prerequisites were no elbow flexion and hand and wrist flexors showing the power of more than Medical research Council MRC Grade 4. Donor nerves selected either ulnar or median having CMAP >4 mv in our electrophysiology laboratory during nerve conduction study. Patients were followed up for 1 year and assessed clinically for restoration of elbow flexion, weight tolerance. Results: A total of 30 patients of Oberlin transfer were evaluated for improvement power of biceps and elbow flexion. (MRC) grading was done at 1 year. Twenty-seven patients had a good result (MRC grade ≥3), i.e., 90% of patients. Based on the MRC grades, we categorised the patients into two groups as follows: Group A and Group B. Group A included patients with MRC Grade 4–5 and Group B included Grades 3–3.5. We tried to establish a correlation between CMAP and MRC scores by comparison of MRC grade patients for their pre CMAPs which revealed a statistically significant higher CMAPs between the groups. (Mann–Whitney U-test, P = 0.028). This indicates the association of higher pre-CMAPs with higher MRC grades. Conclusion: We conclude that higher the compound muscle action potential of donor nerves, better the recovery of elbow flexion in Oberlin transfer in brachial plexus injury.
