Abstract

Nowadays, minimally invasive and non-invasive approaches in aesthetic medicine are increasingly popular and non-surgical rhinoplasty is one of the procedures with rising demand worldwide. In Bulgaria, this procedure seems to be uncommonly performed, since there are no reports in the local scientific literature. The aim of this preliminary study was to briefly explore the possibilities of hyaluronic acid (HA) fillers for correcting three of the most common nasal deformities – dorsal hump, under-projected and under-rotated nasal tip in primary cases. In order to accomplish this objective, a retrospective clinical study was conducted encompassing 11 cases of the authors’ practices with the above mentioned nasal irregularities and no previous surgical/non-surgical treatment. The analysis of patient-reported outcomes suggested a high satisfaction rate, with no major complication in the series. The HA filler has shown to be safe, relatively easily applicable and highly effective for camouflaging nasal deformities. A special emphasis was put on the patient safety and ten golden rules for staying out of trouble were given.

Abstract

Background: Atrial fibrillation is a relatively common complication of acute myocardial infarction with significant impact on the short and long-term prognosis.

Methods: A systematic literature review was done through Pubmed and CENTRAL to extract data related to new-onset atrial fibrillation following primary PCI.

Results: Searching resulted in twenty-one matched studies. Extraction of data showed an incidence rate of new-onset atrial fibrillation (2.8%-58%). A negative impact was found on the outcomes of patients treated with primary PCI with increased short and long-term mortality and morbidity.

Conclusion: New-onset atrial fibrillation is an adverse prognostic marker in patients with acute myocardial infarction treated invasively. Preventive measures and anticoagulant therapy should be considered more intensively in this subset of patients.

Abstract

Introduction: The total knee replacement is the definitive treatment for knee osteoarthritis (OA). It is an effective intervention to correct OA-related functional limitation. In such patients postoperatively are observed significant differences in the biomechanics of the two knee joints. While bearing the body weight the unoperated knee joint becomes very painful, stiff and incapable of neutral positioning. These factors significantly hamper the initial training in gait with aids in the standard locomotive stereotype immediately after surgery for knee joint replacement, where walking plays an essential role in daily activities and has varied health benefits.

Aim: The aim of the study was to check whether different types of gait with aids in the early postoperative period after total knee replacement have a different influence on the recovery process.

Material and methods: This study was conducted between January 2017 and July 2018 in the Department of Orthopedics and Traumatology of the University Hospital “Kanev” – Rousse. It included 56 patients with unilateral total knee replacement after gonarthrosis, divided into a control and experimental group, each of 28 patients. All patients in both groups had knee extension deficit of the untreated knee joint. The patients in both groups followed the same physiotherapy programs, performed from about the 2nd postoperative day to the 21st day when they were discharged from the department. The difference between the patients in both subgroups was their gait pattern with two axillary crutches.

Results and Discussion: There were statistically significant differences between both groups. One of the most significant differences was in ROM. In the experimental group patients, flexion was improved with an average of 20° more than in the control group patients. Also, in the operated joint, the patients in the experimental group had no contracture, whereas those in the control group showed 15° at the end of the follow-up period.

Conclusion: The results of the study show that the choice of gait training in the following order “crutches, operated leg, crutches, untreated leg” in patients with extensor deficiency and contracture in the untreated knee is more appropriate than the standard type of training in walking with aids.

Abstract

The sad news about the death of Acad. Yucel Kanpolat (September 17, 2016), a famous scholar, a pioneer in the field of neurosurgery, and a friend of the Republic of Macedonia, saddened the members of the Editorial Board of the journal PRILOZI of the Department of Medical Sciences of the Macedonian Academy of Sciences and Arts, of which he was a member, as well as the other members of the Academy. Yucel Kanpolat was an international figure, linking Turkey to almost every country in the world. Neurosurgery has lost a very special surgeon, scientist and humanitarian. During the visit to the Macedonian Academy of Sciences and Arts in 2011, we discussed the cooperation between the Turkish Academy of Sciences and the Macedonian Academy of Sciences and Arts, which he respected very much, as well as the role of the academies. He delivered a lecture on The Mission of Academia in the Age of Science, PRILOZI, MASA, XXXII, 2, p. 7-10 (2011), which we reprint in addition.

Abstract

The active metabolite of azathioprine, 6-thioguanine nucleotide (6-TGN) is the main component responsible for the immunosuppressive effect in treatment of inflammatory bowel disease (IBD).

The aim of this study was to assess the correlation between the concentration of 6-thioguanine nucleotide and disease activity, azathioprine-related adverse effects and time duration of treatment in patients with inflammatory bowel disease.

Thirty-four patients were included in this study. Type of disease, gender, time duration of therapy and adverse effects were recorded. Metabolite concentration was determined by high performance liquid chromatography.

Twenty-one percent of patients have experienced an adverse effect, with leucocytopenia most commonly occurring (42.9%). More adverse effects were registered when patients were treated with azathioprine in a period of less than 3 months in comparison to the group of patients that have been under therapy between 3-12 months and more than 12 months (p˂0.05). Most of the patients that presented any adverse effect had high 6-TGN concentration (>450 pmol/8x108 Er). The mean value of 6-TGN metabolite concentration in IBD patients treated with azathioprine was 437.46 pmol/8x108 Er ± 198.82 pmol/8x108. The time duration of azathioprine treatment did not have any significant impact on the achieved 6-TGN concentration (p>0.05).Twenty patients (58.9%) had achieved remission after therapy initiation with azathioprine.

More alertness is recommended to clinicians towards patients in the first 3 months of the therapy. Our study demonstrated that higher 6-TGN concentration is associated with azathioprine toxicity.

Abstract

Background/objectives: Recent data suggest a role for heparanase in several proteinuric conditions. An increased glomerular heparanase expression is associated with loss of heparan sulfate in the glomerular basement membrane (GBM). The aim of the present study was to investigate the renal effects of heparanase inhibition in a diabetic experimental model.

Methods: Fifteen male Wistar rats (230 ± 20 g) were divided into three groups: 1) controls, 2) diabetics (STZ, 50 mg/kg, dissolved in saline, ip), 3) diabetics + heparanase inhibitor (Sulodexide 1/5 mg/kg per day, gavage). The treatment started on the 21st day, for 21 consecutive days. The rats were kept individually in a metabolic cage (8 AM-2 PM) and urine samples were collected on the 21st and 42nd day. At study end blood, urine and tissue samples were collected for biochemical (blood BUN and Cr, urine GAG and Protein) and histological analyses.

Results: The results of this study showed that the heparanase inhibitor (sulodexide) significantly decreased urine GAG and protein excretion, urine protein/creatinine ratio and serum BUN and Cr in streptozotocin-induced DN in the rats. Pathological changes were significantly alleviated in the DN rats having received the heparanase inhibitor (sulodexide).

Conclusion: Our data suggest that the heparanase inhibitor (sulodexide) is able to protect against functional and histopathological injury in DN.

Abstract

The extraction of mandibular third molars is a traumatic procedure accompanied by marked clinical symptoms in the postoperative period. The aim of the present study was to determine the effects of the removal of a partially impacted mandibular third molar on the masticatory efficiency in patients in the early postoperative period.

Material and methods. A total of 47 participants, divided into two groups, took part in this pilot study. The first group included 33 patients with a mean age of 18.3 years (SD = 0.9 years), defined as the Control group; the second group involved patients with a mean age of 33.3 years (SD = 1.86), referred to as the Clinical group. The masticatory efficiency of the Clinical group patients was objectively double-checked using a Protab® test bite: once during the preliminary examination (prior to extraction of the wisdom tooth) and again 7 days after the surgical removal of the wisdom tooth. A sieve analysis was applied to determine the artificial test bite particle size and size distribution following mastication. Feedback on the Clinical group patients’ assessment of any subjective complaints was obtained through a questionnaire containing two questions considered relevant to patients’ masticatory efficiency. The data from the sieve analysis of each fraction were analyzed using the Statistics Software Package for Epidemiological and Clinical Research (IBM SPSS V.20.00).

Results. The data processing of all parameters tested prior to and after extraction of the wisdom tooth revealed statistically significant differences. Only the duration of chewing after the third molar extraction matched the chewing duration in the healthy control subjects (p = 0.198). The analysis of the feedback on the self-assessment of patients from the Clinical group demonstrated that prior to extraction all subjects (100%) experienced pain to a varying degree, whereas in half of the patients (50%) the pain disappeared following extraction. The Spearman’s test for correlation between mean particle sizes as well as the questionnaire feedback indicated a strong positive relationship with food trapping. Accordingly, the larger mean particle size was linked to the self-assessment of food trapping around the wisdom tooth prior to extraction (Spear-man’s Rho = 0.57, p = 0.032). There was also a correlation between the chewing time and the sensation of pain in the teeth adjacent to the extraction wound. The results suggested that the shorter duration of chewing was associated with a greater sensation of pain (Spear-man’s Rho = -0.61, p = 0.026).

Conclusion. The eruption of mandibular third molars causes difficulties in the masticatory process. A positive trend was observed towards normalizing of the chewing duration following extraction (t = -1.356, p = 0.198).

Abstract

Background: Fearful and anxious behaviour is especially common in children, when they come across new situations and experiences. The difference between normal worry and an anxiety disorder is in the severity and in the interference with everyday life and normal developmental steps. Many longitudinal studies in children suggest that anxiety disorders are relatively stable over time and predict anxiety and depressive disorders in adolescence and adulthood. For this reason, the early diagnostic and treatment are needed.

Researchers supposed that anxiety is a result of repeated stress. Additionally, some genetic, neurobiological, developmental factors are also involved in the aetiology.

Methods and subjects: The aim of this article is to summarize and to present our own results obtained with the assessment and treatment of different forms of anxiety disorders in children and adolescents such as: Posttraumatic Stress Disorder (PTSD), Obsessive Compulsive Disorder (OCD), Dental anxiety, General Anxiety Disorder (GAD), and Anxious-phobic syndrome. Some results are published separately in different journals.

a) Post Traumatic Stress Disorder (PTSD) in 10 young children aged 9 ± 2, 05 y. is evaluated and discussed concerning the attachment quality.

b) The group with OCD comprises 20 patients, mean age 14,5 ± 2,2 years, evaluated with Eysenck Personality Questionnaire (EPQ), Child behaviour Checklist (CBCL), K-SADS (Schedule for Affective Disorders and Schizophrenia for School age children), Beck Depression Inventory (BDI), SCWT (Stroop Colour Word task), WCST (Wisconsin Card Scoring test).

c) Dental stress is evaluated in a group of 50 patients; mean age for girls 11,4 ± 2,4 years; for boys 10,7 ± 2,6 years, evaluated with (General Anxiety Scale (GASC), and Eysenck Personality Questionnaire (EPQ).

d) Minnesota Multiphasic Personality Inventory (MMPI) profiles obtained for General Anxiety Disorder in 20 young females and 15 males aged 25,7± 5,35 years, and a group with Panic attack syndrome N=15 aged 19,3±4,9 years are presented and discussed by comparison of the results for healthy people.

e) Heart Rate Variability (HRV) was applied for assessment and treatment in 15 anxious-phobic patients, mean age 12, 5±2,25 years and results are compared with other groups of mental disorder.

Results: Children with PTSD showed a high level of anxiety and stress, somatization and behavioural problems (aggression, impulsivity, non-obedience and nightmares), complemented by hypersensitive and depressed mothers and misattachment in the early period of infancy. Consequently, the explanation of the early predisposition to PTSD was related to be the non-developed Right Orbital Cortex. The later resulted from insecure attachment confirmed in all examined children.

The obtained neuropsychological profile of children with OCD confirmed a clear presence of obsessions and compulsions, average intellectual capacities, but the absence of depressive symptoms. Executive functions were investigated through Event Related Potentials on Go/NoGo tasks. Results showed that no significant clinical manifestations of cognitive dysfunction among children with OCD in the early stage of the disorder are present, but it could be expected to be appearing in the later stage of the disorder if it is no treated.

In a study of 50 children randomly selected, two psychometric instruments were applied for measuring general anxiety and personal characteristics. It was confirmed that there was presence of significant anxiety level (evaluated with GASC) among children undergoing dental intervention. The difference in anxiety scores between girls and boys was also confirmed (girls having higher scores for anxiety). Results obtained with EPQ showed low psychopathological traits, moderate extraversion and neuroticism, but accentuated insincerity (L scale). L scales are lower by increasing of age, but P scores rise with age, which can be related to puberty. No correlation was found between personality traits and anxiety except for neuroticism, which is positively correlated with the level of anxiety.

The obtained profiles for MMPI-201 in a group of patients with general anxiety are presented as a figure. Females showed only Hy peak, but in the normal range. However, statistics confirmed significant difference between scores in anxiety group and control (t= 2, 25164; p= 0, 038749). Males showed Hs-Hy-Pt peaks with higher (pathological) scores, related to hypersensitivity of the autonomic nervous system, as well as with manifested anxiety. Calculation confirmed significant difference between control and anxiety in men (t= 15.13, p=0.000).

Additionally, MMPI profiles for patients with attack panic syndrome are also presented as a figure. Control scales for females showed typical V form (scales 1 and 3) related to conversing tendencies. In addition, females showed peaks on Pt-Sc scales, but in normal ranges. Pathological profile is obtained in males, with Hy-Sc peaks; this profile corresponds to persons with regressive characteristics, emotionally instable and with accentuated social withdraw.

Heart rate variability (HRV) is a measure of the beat to beat variability in heart rate, related to the work of autonomic nervous system. It may serve as a psychophysiological indicator for arousal, emotional state and stress level. We used HRV in both, the assessment and biofeedback training, in a group of anxious-phobic and obsessive-compulsive school children. Results obtained with Eysenck Personality Questionnaire showed significantly higher psychopathological traits, higher neuroticism and lower lie scores. After 15 session HRV training very satisfying results for diminishing stress and anxiety were obtained.

Abstract

Introduction: The aim of the study was to compare the results of two human papillomavirus (HPV) diagnostic techniques: human papillomavirus deoxyribonucleic acid (HPV DNA) testing and human papillomavirus E6/E7 messenger ribonucleic acid (HPV E6/E7 mRNA) testing in women with squamous cell abnormalities of the uterine cervix.

Material and Methods: Comparative prospective study, conducted in the period from January 2016 to June 2017 of 128 sexually active women, age groups of 20 to 59 years (40.50 ± 10.85) with squamous cell abnormalities on the cervical cytology. All patients were subject to: HPV DNA testing, HPV E6/E7 mRNA testing and colposcopic cervical biopsy with endocervical curettage for histopathologycal analysis. HPV DNA testing was done using multiplex polymerase chain reaction (PCR) and reverse hybridization methods. HPV E6/E7 mRNA testing was done using real-time PCR method.

Results: Data analysis showed an association between the results of HPV DNA testing and HPV E6/E7 mRNA testing (p˂0.0001). The concordance between the results of both tests was moderate (55.47%). The results show that HPV E6/E7 mRNA testing had a higer specificity 88.89% and positive predictive value (PPV) 93.59% for HSIL + invasive squamous cell carcinoma compared to HPV DNA testing that had specificity of 55.56% and PPV 84.61%, respectively.

Conclusion: The results of our study suggested that HPV E6/E7 mRNA testing is more specific and has a higher positive predictive value than HPV DNA testing and that viral oncoproteins E6 and E7 are superior biomarkers for the detection of high-risk HPV-associated squamous intraepithelial lesions of the uterine cervix.

Abstract

Objective: Graves’ disease (GD) is characterized by elevated TSH-receptor antibodies (TRAb) and less often – thyroid peroxidase (TPOAb) and thyroglobulin antibodies (TgAb). Our aim was to examine the hormonal and ultrasound characteristics of patients with newly diagnosed GD with differing positive thyroid antibodies.

Materials and Methods: This study included 249 patients with newly diagnosed GD (191 women, 58 men). 40.2% of them had Graves’ ophtalmopathy. The serum levels of TSH, free T4, free T3, TRAb, TPOAb, and TgAb were measured with third generation ECLIA assays (Roche Diagnostics, Switzerland). Thyroid ultrasound was performed with a Fukuda-Denshi 550 device (Fukuda Corp., Japan) and an Ultrasonix device (Ultrasonix Medical Corp., Canada). Statistical analyses were done using the SPSS 23.0 statistical package (Chicago, IL).

Results: 64% of the patients were TPOAb+ and 36% − TgAb+. One third were only TRAb+, 1/3 had two positive antibodies (TRAb + second antibody) and 1/3 – all three positive antibodies. Patients with more positive antibodies tended to be younger, had higher fT4, TRAb levels, thyroid volume but rarely had nodules on US and accompanying GO. Positive TPOAb antibodies were found in younger patients, with higher fT4 and TRAb levels, higher thyroid volume and lower prevalence of nodules and GO. The same trends were found in patients with positive TgAb.

Conclusion: The different characteristics of GD patients with varying thyroid antibody profiles may be due to a variation in the pathogenesis of the disease. An individualized clinical approach may be suitable in those cases.
