<p><strong><em>Objectives: </em></strong><em>To assess by means of cone-beam computed tomography (CBCT) the relative bone density of newly formed bone in rabbit mandibles treated with low-level laser therapy (LLLT) during distraction osteogenesis (DO). </em><strong><em>Methods: </em></strong><em>Seven rabbits underwent surgical osteotomy and immediate installation of a distractor on the mandible (right side). DO was performed for 10 days, and LLLT (aluminum-gallium-arsenide [AlGaAs] infrared laser, λ 830 nm, 40 mW) was applied during distractor activation (days 4-10). Three rabbits were euthanized at the end of the activation period (day 10, group A), and four at the end of the maturation period (day 20, group B). Quality and quantity of newly formed bone in the distracted area were measured on grayscale images using adjacente untreated areas as controls. Two CBCT images were acquired for each animal (before and after removal of soft tissue) to evaluate the influence of the soft tissue on X-ray beam attenuation. </em><strong><em>Results: </em></strong><em>Mean grayscale values in the distracted area were higher in group B rabbits (140.47 vs. 102.55 in group A), indicating greater bone maturation in a short period. Absence of soft tissues during CBCT scanning was associated with higher grayscale values, indicative of less X-ray beam attenuation. </em><strong><em>Conclusions: </em></strong><em>It is possible to measure differences in bone density in areas subjected to DO on CBCT scans, providing an objective assessment useful for monitoring bone quality during the repair process.</em></p><p><em> </em></p>

The restoration processes of damaged or lost bone tissue are an important and topical issue of surgical dentistry and maxillofacial surgery today. According to statistics, diseases that are accompaning by destructive changes in bone tissue occupy one of the dominant places among the nosologies of MFA. Along with the use of updated methods of surgical technique, both before and now the problem of choice of bone-plastic material is relevant, because it is known that osteoplasty opens up great opportunities for complete rehabilitation of patients. The purpose of the study was to determine the effectiveness of our developed osteoplastic composition for the restoration of bone defects in dentistry. Materials and methods. X-ray computed tomography to determine bone density was performed in 26 patients with bone defect replacement "Kolapan-L" (group A), 28 people during augmentation of our proposed osteoplastic composition "Kolapan-L" + multipotent mesenchymal stromal cells + platelet-rich plasma) (group B), and 25 patients where the healing of the bone defect occurred spontaneously (group B). X-ray computed tomography was performed on a 16-slice spiral computed tomography Siemens Somatom Emotionc. Image processing was performed using the program "Dicom". Statistical processing of research results was carried out using conventional methods of variation statistics. Results and discussion. After 1 year of research, the average value of the bone density in patients of group B was probably higher: 1.5 times and 1.8 times relative to the corresponding data in groups A and B. At the same time, the minimum value of the bone density in patients of subgroups A and B was 1.5 times and 1.8 times lower than in persons of group B (p <0.01, p1 <0.01). At the same time, the maximum values of the bone density in patients of group B, where the augmentation of bone defects was performed using our proposed composition, were 1.4 times (p <0.01) and 1.8 times (p <0.05, p1 <0.01) higher than in group A, in the replacement of bone defects "Kolapan-L" and in group B, where the healing of the bone defect was spontaneous, respectively. It was found that in patients of group B after 12 months of studies, the average density of osteoregeneration was 1036.69±55.53 (HU), which was 1.5 times and 1.8 times more than in group A (p <0.01) and in group B patients (p <0.05, p1 <0.01) respectively. Conclusion. The use of tissue equivalent of bone tissue, proposed by us to replace a bone defect based on multipotent mesenchymal adipose tissue cells, contributed to the maximum increase in bone density, with a slightly lower effect of increasing bone density in the augmentation of bone defects

Shoulder pain is a common complication of a stroke which can impede participation in rehabilitation and has been associated with poor outcomes. Low Level LASER Therapy (LLLT) is one of the adjunct treatments of choice with exercise therapy for shoulder rehabilitation in Physiotherapy. The objective of this study was to investigate the effect of LLLT on Hemiplegic Shoulder Pain (HSP) in reducing shoulder pain and improving upper limb function in post Stroke subjects. Prospective study design. 68 subjects with mean age of 53 years having a clinical diagnosis of Stroke with HSP were randomly allocated into two groups. In Group-A (n=34) subjects were treated with LLLT and standardized Rehabilitation Programme, where as in Group-B (n=34) subjects were treated with standardized Rehabilitation Programme. Participants were given interventions twice a week for 8 weeks. The outcomes of this intervention were measured by SPADI for pain, disability and FMA-UE for function. Statistical analysis of the data revealed that within group comparison both groups showed signicant improvement in all parameters, where as in between groups comparison Group-A showed better improvement compared to the Group-B. After 8 weeks of interventions both Group-A and Group-B showed signicant improvement in reducing pain and improving upper limb function. However LLLT along with Standardized Rehabilitation Programme showed more improvement when compared to the Standardised Rehabilitation Programme alone. Thus this study concludes that LLLT is a useful adjunct in HSPalong with rehabilitation

Background: Diabetic wound is a major socioeconomic debilitating problem in this society. Various treatment options are available but still it requires better treatment option. In diabetes mellitus the oxygenation to the tissues is reduced. In this study effects of low level laser therapy were compared with topical application of Streptococcus thermophilus on diabetic wounds that induces formation of new blood vessel and free radical scavenging system, a comparative study to get better treatment option for diabetic wounds.Methods: 18 male rats were selected and divided randomly into three groups. Diabetes was induced in all the rats by using the Alloxan monohydrate at a dose of 120mg/kg of the body weight. Group A was treated with normal saline, group B was treated with low level laser therapy and group C was treated with Streptococcus thermophilus topically. Skin tissues were collected on day three and seven, slides were prepared for microscopic examination to observe the new blood vessels formation.Results: Mean number of new blood vessel formation was observed in group B compared with group A and C. Significant vasculogenesis was seen in group B when treated with Low level laser therapy.Conclusions: In the group of low level laser therapy new blood vessel formation was seen with better wound healing. It means LLLT provides better oxygenation to the tissues by generation of new blood vessels compared with Streptococcus thermophilus and normal saline.

Abstract Objective Postnatal scanty milk secretion is a common complaint. Some physical and medical interventions were advocated to help milk production. These interventions should be effective and safe for the mother and the infant. This study aimed to compare the effects of low-level laser therapy and electroacupuncture on postnatal scanty milk secretion. Study Design A randomized controlled study conducted on 60 healthy primiparous mothers with insufficient lactation. They were randomly divided into three equal groups: group A (control), group B (those who received low-power He–Ne laser beam on both breasts), and group C (those who received faradic current stimulation at Spleen 6, Liver 3, and Small Intestine 1 acupuncture points on both sides). All participants received 10 mg Domperidone three times a day and were given advice about lactation, nutrition, and fluid intake. Evaluation was done before and after the treatment program. Results The mean serum prolactin, infant weight, and visual analog scale (VAS) score were significantly increased in the three groups posttreatment when compared with their corresponding levels pretreatment. Posttreatment serum prolactin was significantly elevated in group C more than the other two groups (p = 0.001 and 0.012, respectively). Also, it was significantly elevated in group B more than in group A (p = 0.001). The mean value of infant weight was significantly elevated in group C when compared with its corresponding values in both groups A (p = 0.001) and B (p = 0.029). The VAS score was significantly increased in both groups B and C when compared with group A (p = 0.001). Conclusion Electroacupuncture is more effective than low-level laser therapy in increasing postnatal scanty milk secretion. Clinical Trial Registration NCT03806062.

Background/Aim. Complex regional pain syndrome type I (CRPS I) is characterized by continuous regional pain, disproportional according to duration and intensity and to the sort of trauma or other lesion it was caused by. The aim of the study was to evaluate and compare, by using thermovison, the effects of low level laser therapy and therapy with interferential current in treatment of CRPS I. Methods. The prospective randomized controlled clinical study included 45 patients with unilateral CRPS I, after a fracture of the distal end of the radius, of the tibia and/or the fibula, treated in the Clinical Centre in Nis from 2004 to 2007. The group A consisted of 20 patients treated by low level laser therapy and kinesy-therapy, while the patients in the group B (n = 25) were treated by interferential current and kinesy-therapy. The regions of interest were filmed by a thermovision camera on both sides, before and after the 20 therapeutic procedures had been applied. Afterwards, the quantitative analysis and the comparing of thermograms taken before and after the applied therapy were performed. Results. There was statistically significant decrease of the mean maximum temperature difference between the injured and the contralateral extremity after the therapy in comparison to the status before the therapy, with the patients of the group A (p < 0.001) as well as those of the group B (p < 0.001). The decrease was statistically significantly higher in the group A than in the group B (p < 0.05). Conclusions. By the use of the infrared thermovision we showed that in the treatment of CRPS I both physical medicine methods were effective, but the effectiveness of laser therapy was statistically significantly higher compared to that of the interferential current therapy.

Objective: The study was designed to evaluate the efficacy of Cyriax physiotherapy versus Cyriaxand Low Level Laser Therapy to compare these techniques in reducing pain and improving gripstrength in patients with lateral epicondylitis. Methodology: The study population included 30patients of lateral epicondylitis (signs and symptoms present for more than 6 weeks) diagnosedin outpatient and indoor facilities of MM Hospital, Mullana. The subjects were selected bymeans of simple random sampling. After fulfilling the inclusion and exclusion criteria, thepatients were randomly allocated in two groups: Group A and Group B. Group A received cyriaxphysiotherapy alone whereas Group B patients were subjected to combined Cyriax and low levelLaser therapy. Baseline measurements of pain and grip strength were taken before treatmentand then at 3 weeks respectively. Results: Our findings showed that there was significantlyhigher improvement in pain and grip strength in Group B (patients receiving combination ofcyriax therapy with low dose laser therapy) as compared to Group A (p<0.05). Conclusion:Cyriax physiotherapy and low level laser therapy were effective in reducing pain and improvinggrip strength after the treatment sessions. But benefits of cyriax physiotherapy with low levellaser therapy in lateral epicondylitis patients are significantly higher as compared to cyriaxphysiotherapy alone over a three week period. Hence, cyriax with low level laser therapy isproved to be a better treatment. Bangladesh Journal of Medical Science Vol.20(2) 2021 p.356-360

Objectives: Plantar fasciitis is a common pain disorder that affects the heel and soles of the feet. These are abnormalities at the location of tendon insertions in the bone and are characterized by scarring, inflammation, or damage to the plantar fascia. Treatment options for patients with plantar fasciitis vary with little consensus on the clinical approach. Physical therapy procedures including LLLT (Low-Level Laser Therapy) are most often applied in conservative treatment of plantar fasciitis. While steroid injection is a treatment that has been proven effective in the management of short-term symptoms. The aim of this study was to compare the effects of LLLT and steroid injection on pain and functional conditions in patients with plantar fasciitis. Methods: This is a prospective study conducted in 30 patients. 15 patients were treated with local injection steroids (single Group A) and 15 patients were treated with LLLT (Group B), 8 J / cm2 per day, 3 days per week for 2 weeks. VAS scores and FFI (Foot Function Index) are measured. Results: Pain intensity was reduced in both groups after 2 weeks. VAS scores decreased to 3.47 in Group A and 3.82 in Group B in 2 weeks (p <0.05). In Group A, FFI decreased to 22.03 ± 4.45 while in Group B it decreased to 26.40 ± 2.52 in the same interval. But generally, patients who suffer from plantar fasciitis prefer LLLT compared to more invasive steroid injection therapy. Conclusion: LLLT therapy and steroid injection are effective methods for reducing pain and improving foot function in plantar fasciitis. It appears that steroid injection is superior to LLLT therapy. But fear of invasive action, patients have LLLT.

Dual energy X-ray absorptiometry (DEXA) measuring tool is a reliable and accurate technology to measure bone density and bone mineral composition. This research examined the composition and bone density (bone mineral composition and bone mineral density) of the whole body and representative body parts using DEXA. The participants were 240 healthy adult men and women who were divided into three groups based on age. The total bone mineral density (BMD) of women amounted to an average of 1.14 g/㎠ in Group A, 1.14 g/㎠ in Group B, and 0.98 g/㎠ in Group C. For men, the average BMD was 1.25 g/㎠ in Group A, 1.20 g/㎠ in Group B, and 1.17 g/㎠ in Group C. As a result, the reduction of age-specific BMD was shown to have a correlation with aging and body mass index(BMI), and it is determined that exercising on a regular basis can prevent reduction in BMD by maintaining appropriate muscle mass.

Abstract Purpose To evaluate the effect of cone-beam computed tomography (CBCT) on radiation exposure, procedure time, and contrast media (CM) use in prostatic artery embolization (PAE). Materials and Methods Seventy-eight patients were enrolled in this retrospective, single-center study. All patients received PAE without (group A; n = 39) or with (group B; n = 39) CBCT. Total dose-area product (DAPtotal; Gycm2), total entrance skin dose (ESDtotal; mGy), and total effective dose (EDtotal; mSv) were primary outcomes. Number of digital subtraction angiography (DSA) series, CM use, fluoroscopy time, and procedure time were secondary outcomes. PAE in group A was performed by a single radiologist with 15 years experience, PAE in group B was conducted by four radiologists with 4 to 6 years experience. Results For groups A vs. B, respectively, median (IQR): DAPtotal 236.94 (186.7) vs. 281.20 (214.47) Gycm2(p = 0.345); EDtotal 25.82 (20.35) vs. 39.84 (23.75) mSv (p =  < 0.001); ESDtotal 2833 (2278) vs. 2563 (3040) mGy(p = 0.818); number of DSA series 25 (15) vs. 23 (10)(p = 0.164); CM use 65 (30) vs. 114 (40) mL(p =  < 0.001); fluoroscopy time 23 (20) vs. 28 (25) min(p = 0.265), and procedure time 70 (40) vs.120 (40) min(p =  < 0.001). Bilateral PAE was achieved in 33/39 (84.6%) group A and 32/39 (82.05%) group B(p = 0.761), all other patients received unilateral PAE. There were no significant differences between clinical parameters and origins of the prostatic arteries (PA) (p = 0.206–1.00). Conclusion Operators with extensive expertise on PAE may not benefit from addition of CBCT to DSA runs, whereas for operators with less expertise, CBCT when used alongside with DSA runs increased the overall radiation exposure.
