The relevance of the topic is related to the necessity for a more detailed study of the effectiveness of surface electromyography as a method for diagnosis of pathological conditions of the teeth-and-jaws system and estimation of the orthopaedic treatment results. The objective of the study was to investigate the effectiveness of using a mastication test while performing surface electromyography in dental patients. We studied and analysed the output of surface electromyograms of m.masseter and m.temporalis obtained from a functional test of the maximum jaw clenching and a mastication test with a food stimulus in 54 persons. The results of the study showed a slight difference in the absolute values between the data of the functional test of the maximum jaw clenching and the mastication test. However, the comparative data of the tests after editing (removal of fragments representing the maximal mouth opening during the mastication from electromyograms in the "Neuro-MSP" program) showed no significant difference in data ($>$0.05) and the maximum approximation of the absolute values of the functional and mastication tests in all cases. Thus, it has been established that in practice the mastication test while performing electromyography in dental patients should be determined and carried out as an additional one in order to clarify the results of treatment. Further studying and establishment of the most effective methods for electromyography is considered to be promising in dentistry.

The aim of this study was to analyse the structural characteristics of the temporo-mandibular joint (TMJ) and the dysfunctional consequences induced by disease in subjects with juvenile idiopathic arthritis (JIA). The study was conducted in 25 patients with JIA (median age (IQR), 13.9 (10.9–15.3)) and 26 healthy controls (median age (IQR), 14.3 (11.6–17.2)) years. All enrolled patients were subjected to anamnestic evaluation, laboratory parameters, JIA subclass, and type of therapy for the disease. A clinical-gnathological evaluation, anamnestic and dysfunctional index (Ai and Di), and magnetic resonance imaging of TMJs were performed in all patients. The test group showed a significant reduction (p < 0.001) regarding the clinical findings such as maximal mouth opening, left and rightward laterotrusion and protrusion, and a significant difference in the reported symptoms (TMJ sounds, reduced mouth opening and pain), and Ai and Di (p < 0.001) compared to healthy patients. Correlation analysis showed a significant correlation between the median duration of disease and the maximum mouth opening and between visual analogue scale (VAS) score and maximum mouth opening, leftward laterotrusion, rightward laterotrusion, and protrusion. The results obtained in this study suggest that patients with JIA presented a cohort of symptoms in TMJs in comparison with healthy controls. Moreover, a careful TMJs evaluation and an early diagnosis of TMJs dysfunction and regular follow-ups are recommended in order to prevent and reduce functional and chewing problems in patients with JIA.

Background and Objectives: Awareness of temporomandibular joint disorder (TMD) is fairly concerning in management of physiotherapy as patients often seek for treatment from orthodontics when pain become their main concerns. In this case, cervical aspects are often overlooked in the treatment of temporomandibular joint disorder. This study aims to determine the effect of cervical extensor strengthening on severity of temporomandibular joint disorder. Methods: A randomized controlled trial study was carried out for 4 weeks to determine the effect of cervical extensor strengthening on severity of temporomandibular joint disorder among university students. A total of 40 participants were recruited via convenient sampling method. Subjects were randomly assigned into two groups: experimental group (E) and control group (C) through lottery randomization. Subjects in experimental group were instructed to perform 1 set of cervical extensor strengthening with 10 repetitions and goldfish exercises whereas subjects in control group were asked to perform goldfish exercises only. A pre-test and post-test severity of TMD, maximal mouth opening and maximal isometric cervical extensor strength were measured for both groups. Results: After 4 weeks of training, there was significant difference in pre-test and post-test severity of TMD and maximal mouth opening for both E and C group. On the other hand, there was significant difference of pre and post-test of maximal isometric cervical extensor strength in experimental group. There was no significant difference in post-test for severity of TMD (p=0.67), maximal mouth opening (p=0.21) and maximal isometric cervical extensor strength (p=0.40) between two groups. Conclusions: The study concluded that, 4 weeks of anti-gravity cervical extensor strengthening exercises protocol showed there was no significantly difference of the severity of TMD and maximal mouth opening between both control and experimental group. On the other hand, goldfish exercises showed significant improvement of maximal mouth opening and reduction in severity of TMD after 4 weeks of intervention period.

ABSTRACT A comparison has been made between (A), a relatively simple method for the measurement of aldosterone secretion rate, based on paper chromatography and direct densitometry of the aldosterone spot and (B) a more elaborate isotope derivative method. The mean secretion rate in 9 normal subjects was 112 ± 26 μg per 24 hours (method A) and 135 ± 35 μg per 24 hours (method B). The »secretion rate« in one adrenalectomized subject after the intravenous injection of 250 μg of aldosterone was 230 μg per 24 hours (method A) and 294 μg per 24 hours (method B). There was no significant difference in the mean values, and correlation between the two methods was good (r = 0.80). It is concluded that the densitometric method is suitable for clinical purposes as well as research, being more rapid and less expensive than the isotope derivative method. Method A also measures the urinary excretion of the aldosterone 3-oxo-conjugate, which is of interest in many pathological conditions. The densitometric method is obviously the less sensitive and a prerequisite for its use is an aldosterone secretion of 20—30 μg per 24 hours. Lower values are, however, rare in adults.

Introduction: Oral Submucous Fibrosis (OSMF) is a precancerous condition of the oral mucosa. It is characterized by excessive production of collagen leading to inelasticity of the oral mucosa and atrophic changes of the epithelium.Aim and objective: To evaluate the efficacy of oral Colchicine in comparison to intralesional injections of Dexamethasone plus Hyaluronidase in the management of OSMF patients.Materials and Methods: Fourty patients with OSMF were randomly divided equally into two groups. 20 patients in Dexamethasone group received biweekly intralesional injections of Dexamethasone (4mg/ml) plus Hyaluronidase 1500 IU in buccal mucosa for a period of 12 weeks. Other 20 patients in Colchicine group received oral Colchicine 0.5 mg tablets twice daily for 12 weeks. Parameters taken in the study were burning sensation, and mouth opening. Descriptive statistics, paired t test and unpaired t test were used for statistical analysis.Results and Conclusions: The pre- and post-treatment differences were found to be statistically significant for both the groups (p<0.001) and for both the treatment outcomes. When the average difference of the treatment outcomes was compared between the two study groups, statistically highly significant difference was noted (p <0.001) only in mouth opening but not in burning sensation.These encouraging results should prompt further clinical trials with Colchicine on a larger sample size to broaden the therapeutic usefulness of the drug in the management of OSMF. JNGMC,  Vol. 14 No. 2 December 2016, Page: 60-65

Abstract Autoimmune diseases are pathological conditions in which the immune system mistakenly attacks its own tissues. This study evaluates the performance of two techniques, which are identifiers of autoantibody specifics: immunoblot and immunodot. This study was conducted in 300 patients of whom 62 were tested positive for antinuclear antibodies. The patients were initially screened for antinuclear antibodies using indirect immunofluorescence. Then, the identification of specific autoantibodies such as anti-extractable nuclear antigens (ENAs) was carried out using the immunoblot and immunodot techniques. The results showed that immunoblot and immunodot did not present a significant difference in their sensitivity against anti-SSA/52, SSB, CENP-B, PCNA, U1-snRNP, Jo-1, Pm-scl, and Mi-2 (p > 0.05). However, the two techniques showed a significant difference in their sensitivity toward autoantibodies anti-DNAn, anti-histone, anti-SmD1, and anti-ds-DNA (p < 0.05). The immunoblot data were in complete accordance with the immunodot data (100%) regarding the detection of autoantibodies such as anti SSA/52, SSB, CENP-B, PCNA, U1-snRP, Jo-1, Pm-scl, and Mi-2, 80% regarding SmD1, and 75% concerning ds-DNA. We should certainly pay closer attention to the efficiency of the techniques used in the diagnosis of autoimmune diseases.

Maximal Mouth Opening

This retrospective study investigated the effects of combining manual therapy and acupuncture on the pain and maximal mouth opening (MMO), which were associated with temporomandibular joint dysfunction (TMD). The 49 TMD patients (15 men, 34 women; mean age = 30.47 years, SD = 13.52 years) were treated with a combination of acupuncture and manual therapy two or three times a week at the hospital. The pain and maximal mouth opening were assessed before and after 1 and 4 weeks of treatment. The combination therapy produced significant changes in pain levels ( p < 0.001) and mouth opening ( p < 0.001). All pairwise non-parametric comparison showed a significant improvement in pain ( p < 0.05 for all pairs) and MMO ( p < 0.05 for all pairs). These findings suggest that combining manual therapy and acupuncture decreases the pain level and increases the MMO of TMD patients. However, future studies should further investigate the efficacy of combined treatment on TMD with more rigorous randomized clinical trials.

Acupoints microcirculatory dynamics vary depending on the body’s health status. However, the functional changes observed during acupoint sensitization, that is, the disease-induced change from a “silenced” to an “activated” status, remain elusive. In this study, the microcirculatory changes at acupoints during sensitization were characterized. Thirty SD rats were randomly divided into five groups: normal control group (N), sham osteoarthritis group (S), light osteoarthritis group (A), mild osteoarthritis group (B), and heavy osteoarthritis group (C). The obtained results showed that the blood perfusion levels at the acupoints Yanglingquan (GB34), Zusanli (ST36), and Heding (EX-LE2) in groups A, B, and C were higher than those in groups N and S on days 14, 21, and 28 (p < 0.01 or p < 0.05). A significant difference in the blood perfusion was also observed at the acupoint Weizhong (BL40) in groups B and C on days 21 and 28 (p < 0.01). In addition, remarkable differences in the level of blood perfusion at the GB34, ST36, and EX-LE2 acupoints were observed on day 28 (p < 0.01 or p < 0.05) among groups A, B, and C. No marked differences in blood perfusion levels were observed at the nonacupoint site among all groups. In conclusion, acupoint sensitization is associated with an increase in the level of local blood perfusion at specific acupoints, and this increase is positively correlated with the severity of the disease. The functional changes in microcirculation at acupoints during sensitization reflect the different physiological and pathological conditions imposed by the disease.

Introduction. The study was to see whether there were differences in values of facial surface electromyography in subjects of good heath by muscles, age, and sex. Methods. It draws ratio between lower value and higher value (R-LV/HV) and asymmetry index (AI), based on root mean square (RMS) from measurement of facial surface electromyography (sEMG) in 154 people of healthy people (male:female = 70:84) aging between more than 20 and less than 70. Results. For R-LV/HV, it averages 81.70±14.60% on frontalis muscle, 73.74±19.12% on zygomaticus muscle, and 79.72±14.77% on orbicularis oris muscle. With analysis of the AI average was 10.87±10.14% on frontalis muscle, 16.71±14.79% on zygomaticus muscle, and 12.10±10.05% on orbicularis oris muscle. Both values were statistically significant in three parts of muscles as shown. Both of R-LV/HV and AI show no statistically significant difference on age and sex (p>0.05). Conclusions. It could provide basic data for the future diagnosis of facial nerve palsy patients by measuring facial sEMG values for healthy people.
