Objective: The main objective of this study is to evaluate the medico-legal aspects of fatal road traffic accidents.
Methods: This is a retrospective study consisting of 80 forensic autopsies performed at the Institute of Legal Medicine – Tîrgu Mureș, Romania during a two years period, between January 1st, 2016 to December 31st, 2017. The information obtained was based on the medical records and the evaluation of autopsy reports.
Results: Male victims involved in road traffic accidents were nearly three times more numerous than women (72.5% vs. 27.5%). Divided into 3 age groups (under 35 years old, 36-59 years old and over 60 years old) we noticed a relatively uniform distribution of the victims, with a slight dominance of the 36-59 age group and the over 60 years of age group. The highest number of victims was among the pedestrians (36.25%), followed in decreasing order by the drivers (33.75%), passengers (17.5%), cyclists (7.5%) and motorcyclists (5%). Positive alcohol testing was found in 14 of drivers (81 %). The analysis of lesions found during necropsies of the deceased at the scene of the accident highlights some particularly life-incompatible injuries that resemble any rescue effort on the part of the medical crew moved to the scene of the accident.
Conclusion: Inappropriate road conditions and indiscipline in traffic of both drivers and pedestrians contribute to unacceptably high mortality.

Objective: The study aims to analyze obesogenic behavioral patterns of adolescents living in Mureş County, Romania, as well as to establish a relationship between these behaviors and their Body Mass Index (BMI), in an attempt to provide effective prevention strategies for obesity.
Material and Methods: 153 students between 9th to 12th grade, aged between 14 and 19 years old, from the Vocational and Art Highschool of Târgu Mureş were included in the study. All the candidates filled out an evaluation questionnaire of lifestyle and risky behaviors. The analyzed data were sex, age, residence, BMI and risky eating behavior defined as the consumption of carbohydrates (bread, potatoes, sweets), sodas, junk food, alcohol (wine, distilled beverages, beer), beer separately, level of physical activity (school and extra-school sports activities), sedentary behaviors (≥2 hours/day in front of a screen: personal computer-PC and television-TV), and spending ≥2 hours/day separately on the PC and on the TV.
Results: A statistically significant association was observed between BMI and consumption of fast-food, tobacco, beer, sedentary behavior and spending ≥2 hours/day in front of the PC. Moreover, there was a statistically significant difference between the BMI values of adolescents presenting all studied risk behaviors compared to those who did not.
Conclusions: Obesity among adolescents from Mureș County is influenced by lifestyle choices like fast-food, tobacco, beer, sedentary behavior and spending ≥2 hours/day in front of the PC.

Introduction: The orthodontic treatment helps in reestablishing a functional occlusion, improving the aesthetics and functionality of the dento-facial complex. A correct alignment of the teeth, through the correction of some dental or skeletal anomalies, enhances the possibilities of dental hygiene, thus reducing the risk of periodontal affections. Nevertheless, the presence of orthodontic appliances in the oral cavity may reduce the efficacy of the means of oral hygiene by creating retentive areas for food, thus producing damages at the level of the marginal periodontium.
Objective: The evaluation of oral hygiene practices for patients in the course of fixed orthodontic therapy and the identification of changes appeared at the level of the marginal periodontium caused by the orthodontic appliances.
Material and methods: A questionnaire with 20 questions was distributed to a number of 129 patients undergoing the active phase of orthodontic treatment in the Orthodontic and Dentofacial Clinic of the Medical Dental School Tîrgu Mureș or in some private practices in the Bucharest metropolitan area.
Results: The majority of patients surveyed are aware of the means of dental hygiene and practice a daily brushing, associated with auxiliary means. The iatrogenic effects of the fixed therapy are represented by gingival recession, gingival overgrowth and bleeding during brushing but these were visible only in the case of a small number of patients.
Conclusions: The fixed orthodontic treatment must be started only after a thorough evaluation of the marginal periodontium, with a close orthodontist – periodontist collaboration and avoidance of jiggling-like movements.

DOI: 10.2478/amma-2019-0022

Objective: Our study aimed to validate the neutrophil-to-lymphocyte ratio (NLR) as a marker for aortic arch calcification in hypertensive patients with less advanced chronic kidney disease (CKD).
Methods: A number of forty-four hypertensive patients with chronic kidney disease (categories G3a and G3b – 2012 KDIGO nomenclature) were included in the study. Considering the presence of aortic arch calcification (AAC) on chest X-ray, the study population was divided into two groups: 27 patients AAC present and seventeen without aortic arch calcification. Laboratory data were collected for each patient and NLR was computed. Comorbidities were also recorded: stable coronary artery disease, lower extremity arterial disease and hypertensive heart disease.
Results: A positive correlation between neutrophil-to-lymphocyte ratio and aortic arch calcification in hypertensive CKD patients was identified. Furthermore, advanced age, increased alkaline phosphatase and increased erythrocyte sedimentation rate had a positive association with aortic arch calcification. We found no statistical correlation between neutrophil-to-lymphocyte ratio and other laboratory features in both groups of patients.
Conclusions: Neutrophil-to-lymphocyte ratio may be viewed as a potential risk factor for vascular calcification in patients with moderate chronic kidney disease; nevertheless, future extensive studies are necessary. In the management of hypertensive patients, general medicine might particularly benefit of this simple, readily available inflammatory marker.

Atrial Fibrillation – An Orchestra of Classic and Modern Risk Factors

Alkora Ioana Balan, Alina Scridon

University of Medicine and Pharmacy Science and Technology of Targu Mures, Romania

DOI: 10.2478/amma-2019-0020

Over the past years, prevention and control of risk factors has begun to play an important role in the management of patients prone to develop atrial fibrillation (AF). A considerable number of risk factors that contribute to the creation of a predisposing substrate for AF has been identified over the years. Although certain AF risk factors such as age, gender, genetic predisposition, or race are unmodifiable, controlling modifiable risk factors may represent an invaluable tool in the management of AF patients. In the recent decades, numerous studies have evaluated the mechanisms linking different risk factors to AF, but the exact degree of atrial remodeling induced by each factor remains unknown. Elucidating these mechanisms is essential for initiating personalized therapies in patients prone to develop AF. The present review aims to provide an overview of the most relevant modifiable risk factors involved in AF occurrence, with a focus on the mechanisms by which these factors lead to AF initiation and perpetuation.

DOI: 10.2478/amma-2019-0019

Objective: The aim of our study is to compare the ability of two nickel-titanium systems that use different rotation motions to create preparations that could promote a complete filling of the apical third of root canals.
Methods: We used 36 freshly extracted teeth, randomly divided in two groups, as follows: in Group A we used ProTaper Next, a system characterized by a continuous rotary motion and in Group B the teeth were instrumented with Wave-One, in which the files have a reciprocating motion. All teeth were root filled based on the same protocol, using gutta-percha and AH Plus. The teeth were further prepared for microleakage evaluation based on dye penetration technique, as follows: immersion in 2% methylene blue, longitudinally sectioned and examination of the apical thirds with an operating microscope. The distance of dye penetration along dentin walls was measured using the ImageJ program.
Results: The comparison between rotational and reciprocating systems showed that reciprocating files significantly promoted a reduced apical microleakage, as demonstrated by unpaired t test, Welch corrected (p=0.0346).
Conclusion: The use of Wave-One Reciprocating system was considered more effective in the shaping of root canals, as they demonstrating better conditions for the hermetic, tridimensional sealing of apical third of the roots canals.

Introduction: Hypertension is one of the most important modifiable risk factor related to cognitive decline and dementia. However, screening for cognitive dysfunction is not part of the routine clinical assessment.
Case presentation: In this report, we present the case of a 75 year old hypertensive male patient with new-onset atrial fibrillation, admitted to the Cardiovascular Rehabilitation Clinic Târgu Mureș. Apart from the routine clinical assessment, the evaluation of cognitive functions was performed with three different screening instruments which identified cognitive dysfunction. Depressive state was assessed with the shortened 13 items form of the Beck Depression Inventory BDI-13 (BDI-13) and it showed moderate depression which could influence the results of cognitive tests. Detection of cognitive impairment was followed by magnetic resonance imaging, which revealed not only hypertension specific microvascular impairment but also a sequelae of a former stroke in the territory of the left middle cerebral artery and a possible meningioma.
Conclusion: Screening for cognitive dysfunction in high-risk hypertensive patients can be easily performed and in several cases like ours, can unmask silent cerebrovascular pathologies, leading to prognostic and therapeutic consequences.

DOI: 10.2478/amma-2019-0017

Objective: The present research aimed to investigate whether a pharmacokinetic drug interaction exists between atomoxetine, a substrate of CYP2D6 and duloxetine, an enzymatic inhibitor of the same metabolic pathway.
Methods: Twenty-three healthy volunteers were enrolled in an open-label, non-randomized, sequential, 2-period clinical study. During the trial, they received a single dose of atomoxetine 25 mg (Period 1:Reference) followed by a combination of atomoxetine 25 mg and duloxetine 30 mg, after a pretreatment regimen with duloxetine 30-60 mg/day for 4 days (Period 2:Test). The pharmacokinetic parameters of atomoxetine and its main metabolite (4-hydroxyatomoxetine-O-glucuronide) were estimated using a non-compartmental approach and statistical tests were used to compare these parameters between study periods.
Results: A total of 22 subjects, extensive metabolizers (EMs), were considered for the final report of the study findings. Duloxetine influenced the plasma concentration-time profile of both parent drug and its glucuronidated metabolite. The pharmacokinetic and statistical analysis revealed that pretreatment with the enzymatic inhibitor increased the mean atomoxetine AUC0–t (from 1151.19±686.52 to 1495.54±812.40 [ng*h/mL]) and AUC0–∞ (from 1229.15±751.04 to 1619.37±955.01 [ng*h/mL]) while kel was decreased and the mean t1/2 was prolonged. With regard to 4-hydroxyatomoxetine-O-glucuronide, Cmax was reduced from 688.76±270.27 to 621.60±248.82 [ng/mL] after coadministration of atomoxetine and duloxetine.
Conclusions: Duloxetine had an impact on the pharmacokinetics of atomoxetine as it increased the exposure to the latter by ~30%. Although the magnitude of this pharmacokinetic interaction is rather small, a potential clinical relevance cannot be ruled out with certainty without further investigation.

Heart failure still represents a real challenge both in everyday practice and research, due to the complex issues related to its pathogenesis and management. Humoral biomarkers have emerged in the last decades as useful tools in the diagnosis, risk stratification and guiding the treatment of heart failure. These molecules are related to different pathological and adaptive processes, like myocardial injury, neurohormonal activation and cardiac remodeling, their most widespread representatives being the natriuretic peptides (e.g. NT-proBNP). The role of altered gene expression and transcription as the basis of myocardial structural and functional changes in heart failure is largely recognized. MicroRNAs (miRNAs) are non-coding RNAs which have a major role in post-transcriptional gene expression by interfering with messenger RNA molecules. Our short review summarizes the molecular biology of miRNAs and their possible role as biomarkers in the diagnosis and prognosis of heart failure. Furthermore, the therapeutical perspectives conferred by these molecules are also presented.
