Relevance. The purpose of the research is to improve the functional diagnosis protocol in prosthodontic treatment of patients with TMD.Materials and methods. The optimal position of the mandible was determined for each patient by two methods: 1) TENS (transcutaneous electrical nerve stimulation) and 2) TENS + kinesiography. Then, the cone-beam computed tomography (CBCT) data were analyzed to determine the most physiological position of the condyles.Results. The analysis of the CT scans of patients without TMD (control group) showed that the right and left condyles occupy an anterior or central symmetrical position relative to the glenoid fossa. In the first and second methods, the condyles occupy an anterior or central position, which is the most optimal position of the lower jaw for the manufacturing of an occlusal stabilization splint. The statistical coefficients allowed us to determine that the second method was more accurate, since the obtained values were lower than those of the first method.Conclusion. Based on the results of this study, we can conclude that the improvement of the protocol, namely a new method for determining the optimal position of the mandible is more time-consuming, but more accurate and allows increasing the effectiveness at all stages of treatment of patients with this pathology.

Thing. The optical density of the lower jaw in the frontal part of female patients was studied, age-related differences in the optical density of the lower jaw were revealed. The aim is to reveal the variability of the values of optical density of the lower jaw in the anterior region in female patients. Methodology. Computed tomograms of the lower jaws of 26 patients were analyzed. The optical density of the bone was assessed using the method of computer densitometry in Hounsfield arbitrary units, measurements were carried out in the area of the root apexes of the lower canines. Statistical analysis was carried out using Microsoft Excel, Windows 9. Results. In 84.6 % of cases, the optical density of bone tissue in the area of 3.3 and 4.3 teeth is within the same class according to the Misch classification. In this group, 72.7 % of patients had class D2, 18.18 ― D1, 9 ― D3; in 15.4 %, the bone density on the right and left sides of the mandible belongs to D2 and D3. The optical density between two relatively symmetrical points is in the range from 2 to 238 units, between the right and left sides it is 129.66 HU. In the group of 30―39 (n = 6) years, in 50 % of cases, bone density belongs to class D2, in 33.33 ― D1, in 16.66 ― D3; 40―49 (n = 8) years in 87.5 % of cases ― D2, in 12.5 ― D1; 50―59 (n = 6) years at 50 % ― D2 and at 50 ― D3; 60―68 (n = 6) years at 50 % ― D2 and at 50 ― D3. Conclusions. With increasing age of patients, there is a decrease in bone density in the lower jaw in the canine area.

Objectives: This purpose of this  case report is to explain the imaging characteristics of unilocular ameloblastoma in CBCT 3D radiograph. Case Report: A 32-year-old male patient came to the dentist complaining his painful right lower jaw over the past few days. Clinical examination showed extensive swelling in the posterior region of the right mandible to cause asymmetry at the inferior border of the mandibular corpus. Panoramic radiography showed radiolucent area in periapical mesial root of 46 tooth, extending to the right angular mandibular with a clearly demarcated shape,  and there was a root resorption of 47 tooth. CBCT 3D examination showed the presence of unilocular radiolucent lesion in a regular shape and a clear borderline, extending to the inferior border of the mandible and causing buccal-lingual cortical perforation accompanied with the resorption of adjacent 47 tooth. Conclusion: CBCT is a supporting radiography that may act as a more accurate diagnostic tool for the diagnosis of unique ameloblastoma lesions.

Objectives: This case report is aimed to describe the features of CBCT in assessing tooth fracture. Case Report: A 50-year-old man came with complaints of discomfort in the right lower jaw area, especially when used for chewing. The results of the percussion test were positive. CBCT examination showed that there was a radiolucent image of the enamel in the middle of the crown root to the 1/3 apical of the mesial and distal roots of tooth 47 which resembled a fracture line. The fracture line also appears to have reached the pulp. In addition, there is a well-defined radiolucent appearance with an irregular shape along the root from the buccal to lingual alveolar crest and accompanied by a decrease in the alveolar crest. The fracture that occurred in this case was from the enamel to the apical and involved the pulp, thus the radiodiagnosis on tooth 47 was a complicated crown root fracture with lateral periodontal cyst. Conclusion: CBCT can be used to help identify tooth fractures by obtaining a more accurate and useful value in differentiating conditions associated with fractures. CBCT provides data on the size and length of the fracture line and the size of the lesion.

Background and Aims: The importance of sessile serrated lesions (SSLs) in the pathogenesis of colorectal carcinoma has been recently established. These are supposed to cause the so-called “interval cancer”, having a rapidly progressive growth and being difficult to detect and to obtain an endoscopic complete resection. We aimed to establish the most important metabolic risk factors for sessile serrated lesions. Methods: We performed a retrospective case-control study, on a series of 2918 consecutive patients who underwent colonoscopy in Gastroenterology and Endoscopy Unit, County Clinical Emergency Hospital, Târgu-Mureș, Romania between 1 st of January 2015-31 th of December 2017. In order to evaluate the metabolic risk factors for polyps’ development, enrolled participants were stratified in two groups, a study group, 33 patients with SSLs lesions, and a control group, 138 patients with adenomatous polyps, selected by systematic sampling for age and anatomical site. Independent variables investigated were: gender, smoking, alcohol consumption, obesity, arterial hypertension, diabetes, hypercholesterolemia, hypertriglyceridemia, hyperuricemia, nonalcoholic liver disease. Results: For SSLs the most common encountered localization was the right colon in 30.55% of cases. By comparative bivariate analysis between SSLs group and control group, it was observed that hypertension (p=0.03, OR 2.33, 95 %CI 1.03-5.24), obesity (p=0.03, OR 2.61, 95 %CI 1.08-6.30), hyperuricemia (p=0.04, OR 2.72, 95 %CI 1.28-7.55), high cholesterol (p=0.002, OR 3.42; 95 %CI 1.48-7.87), and high triglycerides level (p=0.0006, OR 5.75; 95 %CI 1.92-17.2) were statistically associated with SSLs development. By multivariate analysis hypertension and hypertriglyceridemia retained statistical significance. Conclusions: Our study showed that the highest prevalence of SSLs was in the right colon and hypertension and increased triglycerides levels were associated with the risk of SSLs development. These risk factors are easy to detect in clinical practice and may help identifying groups with high risk for colorectal cancer, where screening is recommended.

Thyroid disease often causes unspecific or mild symptoms, so laboratory tests are needed to confirm the functional diagnosis of the thyroid disorder. The laboratory tests which are important to establish the diagnosis of thyroid disorder include: total and free thyroidhormones, its related (thyroid) hormone binding proteins and auto antibodies. The thyroid hormone tests are mostly measured with competitive or sandwich immunoassays and each method can be interfered by several factors. Some drugs may increase or decrease thethyroid functional tests and several factors such as: underlying diseases, age, pregnancy, occurrence of heterophil antibody and auto antibodies may also interfere the thyroid tests results. The interpretation of an unusual combination from thyroid stimulating hormonesuch as free thyroxin and tri-iodothyronine results needs confirmation of underlying condition for establishing the right diagnosis. This review is aimed to evaluate several factors which may influence the thyroid tests and interpretation.

Primary cutaneous follicle center lymphoma (PCFCL) accounts for the majority of primary cutaneous B-cell lymphomas. We report a 60-year-old womanwith PCFCL. She had a red nodule (25 × 25 mm) on the right side of the lower jaw. She was diagnosed with PCFCL by skin biopsy. And then, she was treated with radiation therapy (total 30.6 Gy), which completely eliminated the nodule. Our case suggests that radiation therapy may be a first choice for PCFCL patients with a solitary lesion or localized lesions.

The aim of this study was to identify correlations between electrocardiographic and echocardiographic changes in patients with silicosis prior to the occurrence of chronic pulmonary heart disease. We conducted a prospective, descriptive, analytical study, in which we included a group of 67 patients consecutively admitted to the Health Promotion and Occupational Medicine Clinic between December 2016 and January 2018, aged 47 to 78 years.There was a biochemical and electrocardiographic evaluation for each patient as well as a right ventricle echocardiographic evaluation (diameters, volumes, function). A control group, including 25 patients with benign minor diseases that required a cardiologist consultation, was also used. From the electrocardiographic point of view, slight changes were observed regarding the waves of electrical activity of the right ventricle. Taking into account the degree of ventilatory dysfunction (depending on FEV1), changes in right heart echocardiographic parameters were identified. Thus, in what the most important right ventricular parameters, including the tricuspid annular plane systolic excursion (TAPSE) or the RV index of myocardial performance (RVMPI) were concerned, values at the upper limit of normality were recorded in most patients with moderate and severe ventilatory dysfunction. Values of echocardiographic parameters of the right heart at the upper limit of normality, correlated with the degree of ventilatory dysfunction, are early markers for cardiovascular damage in patients with pulmonary silicosis prior to the occurrence of chronic pulmonary heart disease also known ascor pulmonale.

Background: Shear wave electrography (SWE) is a novel non-invasive imaging technique which demonstrate tissue elasticity. Recent research evaluating the elasticity properties of normal and pathological tissues emphasize the diagnostic importance of this technique. Aims: Polycystic ovarian syndrome (PCOS), which is characterized by menstrual irregularity, hyperandrogenism, and polycystic overgrowth, may cause infertility. The aim of this study was to evaluate the elasticity of ovaries in patients with PCOS using SWE. Methods: 66 patients diagnosed with PCOS according to the Rotterdam criteria (PCOS = group I) and 72 patients with non-PCOS (Control = group II), were included in the study. Demographic and clinical characteristics of the participants were recorded. Ovarian elasticity was assessed in all patients with SWE, and speed values were obtained from the ovaries. The elasticity of the ovaries was compared between the two groups. Results: While there were statistically significant differences between the groups in body mass index (BMI), right and left ovarian volumes, luteinizing hormone and testosterone levels (p<0.05), no significant differences were found between groups I and II in the velocity (for the right ovary 3.89±1.81 vs. 2.93±0.72, p=0.301; for the left ovary 2.88±0.65 vs. 2.95±0.80, p=0.577) and elastography (for the right ovary 36.62±17.78 vs. 36.79±14.32, p=0.3952; for the left ovary 36.56±14.15 vs. 36.26±15.10, p=0.903) values, respectively. Conclusion: We could not obtain different velocity and elastography values from the ovaries of the patients with PCOS using SWE. Therefore, further large-scale studies are needed to elucidate this issue.

Electrical Nerve Stimulation

Background: Transcutaneous Electrical Nerve Stimulation (TENS) is a non-invasive pain therapy that uses the sensory effects of an electrical current applied to the skin. Some clinical studies demonstrated that this treatment helps to reduce acute and chronic pains, while others gave sometimes contradictory or uncertain conclusions about the performances of this strategy according to pathology classification. The purpose of this study is the development and evaluation of a new modulated version of transcutaneous electrical nerve stimulation called PWM-TENS. The principle is based on an automatic variation of the stimulation parameters (frequency, amplitude, duration, shape, cyclic ratio) according to the pain evolution. Methods: The study was a controlled clinical trial involving 15 participants, divided into 2 groups. The first experimental group performed modulated PWM-TENS electro-stimulation sessions applied to the painful areas 3 to 4 times a day, for one month. The second control group did parallel treatments by Placebo. The evaluation of the pain intensity is done with the Visual Analog Scale (EVA), the DN4 and SF36 questionnaires. Results: The tests and measurements with our embedded PWM-TENS technique demonstrated that we succeeded to increase the analgesic effect after stopping the stimulation and reduced the pain sensation by about 60%. An improvement in pain intensity scores and questionnaires (EVA, DN4), as well as the quality of life score (SF36), was observed. Also, a reduction of the treatment period from 3 to 1 month was also obtained. Conclusion: The first results clinically observed in the PWM-TENS technique are encouraging. The findings of this study confirm that this noninvasive strategy is suitable and useful for acute pains coming from the nociceptive, neuropathic and musculoskeletal origin. However, its efficiency is moderated and less adapted for low back pain. The experiments make it possible to estimate whether this modulated TENS method could improve existing anti-pain therapies, taking into account objective and subjective evaluation criteria. But this study must be followed by large population samples to answer all the problems of acute and chronic pains.

The aims of this study were to develop and validate an instrument to quantitatively assess the handedness of basketballers in basketball tasks (Basketball Handedness Inventory, BaHI) and to compare it with their handedness in daily activities by the Edinburgh Handedness Inventory (EHI). The participants were 111 basketballers and 40 controls. All subjects completed the EHI and only basketballers filled in the BaHI. To validate the BaHI, a voluntary subsample of basketballers repeated the BaHI. Exploratory and confirmatory factor analyses supported a two-factor model. Our results show that: (i) Handedness score (R) in daily actions did not differ between basketball players (R by EHI = 69.3 ± 44.6) and the control group (R by EHI = 64.5 ± 58.6); (ii) basketballers more frequently favored performing certain sport tasks with the left hand or mixed hands (as highlighted by R by BaHI = 50.1 ± 47.1), although their choice was primarily the right hand in everyday gestures; and (iii) this preference was especially true for athletes at the highest levels of performance (R by BaHI of A1 league = 38.6 ± 58.3) and for those playing in selected roles (point guard’s R = 29.4 ± 67.4). Our findings suggest that professional training induces handedness changes in basketball tasks. The BaHI provides a valid and reliable measure of the skilled hand in basketball. This will allow coaches to assess mastery of the ball according to the hand used by the athlete in the different tasks and roles.
