ABSTRACT

OBJECTIVE: To compare the results of surface electromyography in patients with functional disorders of the masticatory muscles at all stages of complex therapy and to demonstrate the need for the introduction of a generally accepted comprehensive approach to the examination and treatment of patients with this pathology.

MATERIAL AND METHODS: EMG studies were conducted in 127 patients of both sexes aged 35 to 54 years, who were divided into 2 groups. The first (control group) consisted of 20 patients without signs of functional disorders in the masticatory muscles. The second (main) group included 107 patients of both sexes with functional disorders in the masticatory muscles. The examination was carried out using a portable electromyograph “Synapsis” (Neurotech), adapted for dental purposes.

RESULTS: The application of surface electromyography in patients with functional disorders of the masticatory muscles revealed statistically significant differences in the values of the compared indices. EMG allowed for a visual assessment of the work of the masticatory musculature based on the results of qualitative and quantitative indicators of the bioelectrical activity of the masticatory muscles.

CONCLUSION: Performing surface EMG at all stages of rehabilitation is of undeniable value as the most accessible and informative method for diagnosing neuromuscular disorders in patients with increased tooth wear and masticatory muscle dysfunction, which improves the quality of orthopedic treatment.

ABSTRACT

OBJECTIVE: To study the frequency of visits to dental surgeons in different subjects of the Russian Federation.

MATERIAL AND METHODS: The work used the data of sectoral statistical observation for 2017-2023 presented in the statistical compilations of the Ministry of Health of Russia on resource provision in federal districts and subjects of the Russian Federation for 2018, 2020, 2022 and 2024. Statistical and analytical methods of research were used in the work.

RESULTS: It was found that the highest attendance rate of dental surgeons nationwide was recorded in 2018 and 2019. During the COVID-19 pandemic period from 2019 to 2021, specialist attendance decreased by 10.5%. However, despite the imposed restrictive measures during the COVID-19 pandemic the number of visits to dental surgeons for the disease increased in 17.6% of the subjects of the Russian Federation. After the COVID-19 pandemic (from 2022 to 2023) the rate in general increased by 0.5%. In the period under study, the dynamics of attendance of dental surgeons in the country as a whole remains negative with a decrease of 9.9%.

CONCLUSION: The increase in the frequency of visits to dental surgeons among the population of the Russian Federation both during the COVID-19 pandemic and after it indicates an increase in the medical activity of the population in maintaining dental health.

ABSTRACT

OBJECTIVE: Evaluation of the effectiveness of treatment of chronic generalized periodontitis by PDT method based on PCR diagnostic data.

MATERIAL AND METHODS: A clinical and laboratory study and treatment of chronic generalized periodontitis of moderate severity was conducted in 30 people (16 men and 14 women) aged 35 to 55 years without somatic pathology with orthognathic bite diagnosed according to ICD-10 K05.3. Complex treatment consisted of oral sanitation, removal of dental plaque and curettage of periodontal pockets followed by photodynamic therapy (4 sessions of 10 minutes each). Bacteriological examination was performed before and after PDT. The test material was collected from inflammation sites in the gingival sulcus area and from periodontal pocket areas. DNA determination of Prevotella intermedia, Tannerella forsythia (Bacteroides forsythus), Treponema denticola, Aggregatibacter actinomycetemcomitans (Actinobacillus actinomycetemcomitans) and Porphyromonas gingivalis was performed using the reagent kit Multident-5 by the method of accelerated sample preparation using reagents manufactured by Genlab LLC in accordance with the manufacturer’s instructions. The results were assessed by a semi-quantitative method (in points from 0 to 4).

RESULTS: According to PCR diagnostics, a positive trend was observed in patients after PDT treatment. The decrease in the frequency of A. actinomycetemcomitans DNA detection after treatment was not statistically significant. At the same time, A. actinomycetemcomitans was identified in 17 (85%), after therapy in 15 (80%) indivisuals. The frequency of P. intermedia detection after therapy decreased from 15 (40%) to 0 (0%) cases. The frequency of P. gingivalis DNA detection decreased by 1.4 times: from 18 (90%) cases before treatment to 13 (65%) after treatment. One month after PDT, the frequency of P. gingivalis DNA detection decreased by 2 times, and after 3 months by 1.4 times. T. forsythia was detected before treatment in all patients, after treatment in 18 cases (90%). One month after PDT, it decreased significantly and was completely eliminated, which remained the case after 3 months. T. denticola was detected in 16 (80%) patients before treatment and in 14 (70%) people after treatment.

CONCLUSIONS: PDT resulted in a significant reduction in the bacterial load in patients with moderate chronic generalized periodontitis.

ABSTRACT

OBJECTIVE: To study the expression of NOD-like receptors (NLRs) in periodontal tissue cells of patients with aggressive periodontitis before and after complex treatment.

MATERIAL AND METHODS: An immunohistochemical study of NLR expression (NOD1, NOD2, NLRC3, NLRP3, NLRP7, NLRP12, NAIP) was performed in periodontal tissue samples from patients with aggressive periodontitis before and after complex treatment, as well as in samples of the gingival mucosa of patients with gingival fibroids without signs of inflammation, who served as a control group.

RESULTS: In the control group, NLR expression in the multilayer squamous epithelium of the gingival mucosa was not detected. In patients with aggressive periodontitis, during the exacerbation period, pronounced expression of all studied NLRs was revealed in the inflammatory infiltrate cells of the subepithelial tissues of the periodontal pocket, as well as NOD1, NLRP3, NLRP12 and NAIP in the nuclei and cytoplasm of the cells of the multilayer squamous epithelium of the periodontal pocket. During complex treatment, the expression of most NLRs in epithelial cells persists for 21 days, while it decreases in the inflammatory infiltrate cells of the subepithelial tissues of the periodontal pocket.

CONCLUSION: Statistically significant differences between IHC expression parameters before and after treatment according to the criterion of “inflammatory infiltrate” were found among such receptors as NAIP, NLRP12 and NLRP7.

ABSTRACT

OBJECTIVE: To study the dental status of patients depending on the presence of precancerous diseases of the oral mucosa.

MATERIAL AND METHODS: For the first time in the Ryazan region 1857 people aged 18 to 89 years were examined. To assess the dental status of patients the CFE (DMFT) index and the OHI-S hygienic index (Green, Vermillion, 1964) were used, the presence of orthopedic structures was noted.

RESULTS: During the examination 1700 (92.34%) patients did not have diseases of the oral mucosa, while 141 (7.66%) had precancerous diseases: leukoplakia, lichen planus, papilloma and papillomatosis of the palate. The highest value of the CFE index was found in women aged 60-74 years, as well as in men and women aged 75-89 years, both among patients with and without precancerous diseases of oral mucosa. When analyzing the data of individual components of the CFE index of patients with precancerous diseases of the oral mucosa, the predominant C index (caries) was identified in the group of men aged 45-59 years, a high value of the F index (filling) was obtained among women aged 18-44 years. There were equally many extracted teeth (an indicator E of the CFE index) in men and women aged 75-89 years, both in the group of patients with precancerous diseases of the oral mucosa and in the group of patients without them. A significantly higher number of orthopedic structures were found in patients diagnosed with leukoplakia (44 people – 61.11%). A satisfactory level of hygiene was diagnosed in all age groups of patients with both precancerous diseases of the oral mucosa and healthy patients.

CONCLUSION: Based on the results of the study of the dental status, the absence of differences in the CFE index and its individual components, the OHI-S index, and the number of orthopedic structures between groups of patients with and without precancerous diseases of the oral mucosa was obtained and statistically proven. A statistically significant higher number of orthopedic structures was shown in patients diagnosed with leukoplakia in comparison with the group of patients without pathological changes of the oral mucosa.

ABSTRACT

OBJECTIVE: The aim of this study was to observe the effect of clomiphene citrate on sperm parameters in infertile men diagnosed with idiopathic oligoasthenozoospermia.

METHODS: This randomized controlled trial involved 50 infertile men diagnosed with idiopathic oligoasthenozoospermia, all of whom had normal serum testosterone and follicle-stimulating hormone levels. The participants were divided into two groups. The first group (n=25) received a daily dose of 50 mg of clomiphene citrate in tablet form for 3 months, while the second group (n=25) was given a placebo. Sperm concentration, sperm motility, and serum testosterone levels were measured at the start of the study and after 3 months of treatment. Changes in these parameters were then assessed and compared between the two groups.

RESULTS: There was a significant increase in the mean sperm count (9.17±4.11 million/mL vs. 13.88±7.27 million/mL), progressive motility (14.67±7.03 vs. 21.42±11.9), total motile sperm count (3.53±3.08 million vs. 7.81±7.10 million), and mean serum testosterone levels (371.97±88.51 ng/dL vs. 805.94±290.77 ng/dL) in the clomiphene citrate group. In contrast, the changes in the placebo group were not significant. Post-treatment severe oligozoospermia was substantially lower in the clomiphene citrate group (odds ratio, 0.31) compared to the placebo group. Additionally, half of the participants in the clomiphene citrate group experienced a statistically significant upgrade in World Health Organization (WHO) sperm concentration categories, versus 27.3% in the placebo group.

CONCLUSION: Clomiphene citrate improves sperm count and motility, leading to upgrades in WHO sperm concentration categories in infertile men with idiopathic oligoasthenozoospermia.

ABSTRACT

BACKGROUND/AIMS: The effectiveness of colonoscopy largely depends on the quality of bowel preparation. Polyethylene glycol (PEG) is commonly used but has certain limitations. This review evaluates whether combining PEG with linaclotide improves preparation efficacy and safety compared with PEG alone.

METHODS: A search was conducted in Medline, Embase, and ClinicalTrials.gov up to October 2024. Only randomized controlled trials comparing PEG combined with linaclotide versus PEG alone and reporting adenoma detection rates (ADR) or polyp detection rates (PDR) were included. Mean differences (MDs) and risk ratios (RRs) with 95% confidence intervals (CIs) were reported.

RESULTS: A total of eight studies, including 3,071 participants, were included. Pooled analysis indicated that PEG combined with linaclotide was significantly associated with a higher ADR (RR, 1.15; 95% CI, 1.03-1.28), higher Boston bowel preparation scale score (MD, 0.31; 95% CI, 0.02-0.61), and greater willingness to repeat colonoscopy (RR, 1.16; 95% CI, 1.08-1.24). Although PDR (RR, 1.05; 95% CI, 0.89-1.24) was numerically higher in the intervention group, the difference was not statistically significant. Additionally, the intervention significantly reduced the incidence of nausea, vomiting, bloating, and abdominal pain.

CONCLUSIONS: PEG combined with linaclotide is a safe alternative to PEG alone, improving ADR, bowel preparation quality, and patient comfort.

ABSTRACT

BACKGROUND/AIMS: Endoscopic retrograde cholangiopancreatography (ERCP) is conventionally performed in the prone position (PP). Recent studies have shown that the supine position (SP) is an effective alternative, with comparable success rates. We conducted a meta-analysis to directly compare the safety and efficacy of the two ERCP positions.

METHODS: In line with Cochrane and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic review was performed through a comprehensive search of PubMed, Embase, Web of Science, and the Cochrane Library. Statistical analyses were performed using RevMan, with results considered significant at p<0.05 and reported as odds ratios (ORs) and mean differences (MDs).

RESULTS: Eleven studies (24,285 patients) were included in the final analysis. Procedural success was significantly higher in the PP (OR, 0.52; 95% confidence interval [CI], 0.36-0.75; p<0.0004) than the SP. However, no significant difference was observed in procedure times (MD, 0.22; 95% CI, -7.07 to 7.50; p=0.95), number of cardiopulmonary complications (OR, 1.08; 95% CI, 0.47-2.48; p=0.86), or post-ERCP pancreatitis (OR, 1.12; 95% CI, 0.52-2.42; p=0.31) between the two groups.

CONCLUSIONS: The PP demonstrates superior ERCP success compared to the SP, without prolonging procedure time or increasing the risk of adverse events. However, given the comparable procedure times, incidence of adverse events, and increased comfort for both patients and anesthesiologists, the SP may be a suitable alternative for a select group of patients in whom the PP is not feasible, such as those with morbid obesity or recent abdominal surgery.

ABSTRACT

AIM: This study aimed to reveal demographic data for care-dependent older adults receiving home medical care and to evaluate whether potentially inappropriate medication (PIM) prescriptions were associated with hospitalization and death.

METHODS: Data of health-care and long-term care insurance claims of older adults aged ≥65 years receiving home medical care of Kure City, Japan in April 2017 were obtained. They included age, sex, recorded diagnosis on medical claims, level of long-term care (LTC) needs, and medication profile. Hospital admissions and deaths were identified between April 2017 and April 2019. Factors associated with hospitalization/death and PIM (≥1 PIM) defined by STOPP-J were analyzed statistically.

RESULTS: A total of 2052 participants (mean age 86.5±7.4 years, female 71.7%) were included. The mean number of prescribed medications was 6.6±4.3. PIM increased as LTC level became severer (8.7% for support level 1 and 2, 22.6% for care level 1 and 2, 26.0% for care level 3 to 5). Among PIM, H2 receptor antagonists were the most common medication (29.0%), followed by antiplatelet agents (22.6%), magnesium oxide (19.4%), non-benzodiazepine sedatives (17.7%), and benzodiazepines (16.8%). On logistic regression analysis, the number of medications, PIM, and care level 1 and 2 were associated with higher likelihood of hospital admission. There was no significant correlation between each PIM and hospital admissions. Regarding death, while age was associated with higher likelihood, female gender and severer level of disability were associated with lower likelihood.

CONCLUSIONS: PIM was prevalent among homebound older adults, suggesting that careful medication review should be conducted especially in those with disability.
