Summary

The objective of this study was to test the clinical effectiveness of the gallium-aluminum-arsenide laser (GaAlAs; 785 nm) and superluminiscent diodes (633 nm) phototherapy (MedX 1100 device) for the treatment of patients with temporomandibular disorders and myofascial pain syndrome. The results demonstrated a positive effect in pain relief. A significant reduction (p < 0.05) in the level of pain was observed for the temporomandibular joint and for the masseter muscles using paired samples t-test and Wilcoxon signed rank test. The experimental study on pork muscle samples showed that a) the main part of laser radiation is absorbed by the tissue in thin layer of 3-4 mm, b) in the spectral region 650-950 nm the intensity of light penetration is about 0.2-0.25 percent of the initial light intensity.

Summary

Out of 19,046 goats aged between 5 and 6 month and slaughtered at an abattoir in Dubai between September 2012 and March 2014, 57 carcasses were objected at meat inspection due to the presence of bladder worms of the coenurus type. The majority showed single cysts that were cut out but 10 carcasses had to be discharged due to the presence of multiple cysts and with a maximum number of 41 coenuri. In the majority of carcasses, cysts were located in the legs (n=45) followed by abdominal muscles (n=16), diaphragm (n=14) and shoulder (n=13). Loin, rack, renal fat, heart, neck, masseter were other cyst locations. The size of the detected parasitic cysts ranged from 0.7 ml to 90 ml. The maximum number of 1,102 scolices was counted in an 86 ml coenurus found in the leg of a goat. Cysticercus tenuicollis was another cestode larval stage found in livers of 302 goats. A mixed infection with both parasites was detected in 35 carcasses.

Abstract

Introduction. Pathological muscle tone can cause changes in the facial skeleton, including tension headaches, tinnitus, temporomandibular joint dysfunctions. The complexity of pathologies and their spectrum may also indicate changes beyond the facial skeleton. The aim of the study was to determine the possible correlation between the pressure pain threshold of the trapezius muscle and the bioelectrical tension on the masticatory muscles.

Aim. The aim of the study was to determine the possible correlation between the pressure pain threshold of the trapezius muscle and the bioelectric tension on the masticatory muscles.

Material and methods. The number of 36 women applied for the study. They were all examined using an algometer within a trapezius muscle to determine the pressure pain threshold. The electromyographic study was carried out in accordance with the SENIAM guidelines. The resting activity of selected masticatory muscles (temporal and masseter) was recorded for 10 sec. The study involved an 8-channel BioEMG IIITM surface electromyography apparatus with BioPak Measurement System (BioResearch Associates, Inc. Milwaukee, WI, USA). Statistical analysis was carried out using the r-Pearson test. The level of significance was set at 5%.

Results. After comparing the bioelectric tension of the masticatory muscles and the pressure pain threshold, left-sided correlation was observed (p<0.05). Both in the right-hand and general comparison, the results did not reach the required level of statistical significance (p>0.05).

Conclusions. The pressure pain threshold seems to be linked to the bioelectrical muscle tone of the masticatory muscles. To confirm this observation, further research into a larger and more diverse group of participants is recommended.
