Short-term outcomes of cranial cruciate ligament rupture treated surgically with tibial plateau leveling osteotomy or non-surgically in small-breed dogs weighing less than10 kg. J Vet Med Sci 2024; 86:428-435. [PMID: 38417876 PMCID: PMC11061578 DOI: 10.1292/jvms.23-0512] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Accepted: 02/12/2024] [Indexed: 03/01/2024] Open
Abstract
Cranial cruciate ligament rupture (CCLR) is a common cause of stifle joint pain in dogs. This study assessed the short-term outcomes in the management of CCLR, with or without concurrent medial patellar luxation (MPL), in small-breed dogs, comparing surgical intervention using tibial plateau leveling osteotomy (TPLO) with non-surgical approaches. Dogs weighing less than 10 kg and suffering from CCLR were divided into two groups: surgical and non-surgical (nine stifles per group). Both groups followed the same rehabilitation protocol. Measurements were taken on days 0, 14, 28, 42, 56, 70, and 84. These measurements included the mean difference in orthopedic assessment score (diffOAS) and thigh muscle circumference (TMC) assessed by veterinarians, as well as the Canine Brief Pain Inventory score (CBPI) evaluated by the owners. Six stifles had concurrent MPL in the surgical group and five in the non-surgical group. No significant differences were observed in diffOAS (P=0.685), TMC (P=0.557), CBPI pain severity score (P=0.062), and CBPI pain interference score (P=0.29) between the two groups. However, both groups showed a significant decrease (P<0.05) in diffOAS and CBPI. The TMC remained relatively stable in the non-surgical group (P>0.05), but it significantly increased in the surgical group (P<0.05). Both groups demonstrated improved clinical outcomes in the short term, with no significant differences. However, cautious consideration should be given to a conservative treatment in small-breed dogs, particularly when considering the exclusive improvement observed in TMC within the TPLO group.

Effectiveness of multiwave locked system laser on the treatment of patients with idiopathic Bell's palsy: a randomized double-blind placebo controlled trial. Lasers Med Sci 2022; 37:3495-3502. [PMID: 35881208 DOI: 10.1007/s10103-022-03616-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Accepted: 07/19/2022] [Indexed: 10/16/2022]
Abstract
The objective of this study is to investigate the effect of scanning and point application of multiwave locked system (MLS) laser therapy on the recovery of patients with idiopathic Bell's palsy (IBP). A randomized double-blind placebo-controlled trial was carried out on 60 patients with subacute BP. Patients were randomly assigned into three groups of 20 patients each. Facial massage and facial exercises were applied to all patients. Group one received MLS laser as a manual scanning technique (10 J/cm2, area 50cm2, total energy 500 J). Group two received MLS laser using point application technique (10 J/point, 8 points, total 80 J). Group three received placebo laser. House-Brackmann scale (HBS) and facial disability index (FDI) were used to evaluate the facial recovery. Assessment was performed at baseline and after 3 and 6 weeks of treatment. Comparison within and between groups was performed statistically with significance level p < 0.05. Results showed significant improvement in the FDI and HBS after treatment in all groups. Both scanning and point application significantly improved the score of FDI and HBS more than placebo group. Scanning technique combined with facial massage and exercises had a more significant effect than the point application group or the placebo group in improving FDI and HBS scores after 3 and 6 weeks of treatment. The MLS laser is an effective physiotherapy method used for the treatment of patients with IBP. MLS laser in scanning or point application techniques was more effective than exercise alone with greater effect of scanning technique than point application technique.

Abstract
Raynaud's phenomenon (RP) is a multifactorial vasospastic disorder characterized by a transient, recurrent, and reversible constriction of peripheral blood vessels. RP is documented to affect up to 5% of the general population, but variation in its prevalence is commonly recognized owing to many factors, including varied definitions, gender, genetics, hormones, and region. Furthermore, RP may be idiopathic or be a clinical manifestation of an underlying illness. Patients with RP classically describe a triphasic discoloration of the affected area, beginning with pallor, followed by cyanosis, and finally ending with erythema. This change in color spares the thumb and is often associated with pain. Each attack may persist from several minutes to hours. Moreover, the transient cessation of blood flow in RP is postulated to be mediated by neural and vascular mechanisms. Both structural and functional alterations observed in the blood vessels contribute to the vascular abnormalities documented in RP. However, functional impairment serves as a primary contributor to the pathophysiology of primary Raynaud's. Substances like endothelin-1, angiotensin, and angiopoietin-2 play a significant role in the vessel-mediated pathophysiology of RP. The role of nitric oxide in the development of this phenomenon is still complex. Neural abnormalities resulting in RP are recognized as either being concerned with central mechanisms or peripheral mechanisms. CNS involvement in RP may be suggested by the fact that emotional distress and low temperature serve as major triggers for an attack, but recent observations have highlighted the importance of locally produced factors in this regard as well. Impaired vasodilation, increased vasoconstriction, and several intravascular abnormalities have been documented as potential contributors to the development of this disorder. RP has also been observed to occur as a side effect of various drugs. Recent advances in understanding the mechanism of RP have yielded better pharmacological therapies. However, general lifestyle modifications along with other nonpharmacological interventions remain first-line in the management of these patients. Calcium channel blockers, alpha-1 adrenoreceptor antagonists, angiotensin-converting enzyme inhibitors, nitric oxide, prostaglandin analogs, and phosphodiesterase inhibitors are some of the common classes of drugs that have been found to be therapeutically significant in the management of RP. Additionally, anxiety management, measures to avoid colder temperatures, and smoking cessation, along with other simple modifications, have proven to be effective non-drug strategies in patients experiencing milder symptoms.

Abstract
Background/aims Osteoporosis is a systemic disorder characterised by a decrease in bone quality and density. This causes the bones to become weak and unable to withstand mild stresses, and the associated pain is made worse with activities. The aim of this study was to investigate the effect of class IV laser therapy and Pilates exercises on bone mineral density and pain in patients with primary osteoporosis. Methods A total of 60 patients with osteoporosis (40 women and 20 men) participated in this study. Their age ranged between 40 and 60 years. They were allocated randomly to three groups: Group A (n=20) received multiwave locked system laser therapy, group B (n=20) patients received Pilates exercises and group C (n=20) received multiwave locked system laser therapy and Pilates exercises. The treatment programme took place three times a week for 8 weeks. Bone mineral density of the lumbar spine (L1–L4) was measured by dual-energy X-ray absorptiometry and pain intensity during activities was measured by using the Numeric Pain Rating Scale. Evaluation of lumbar bone mineral density and pain intensity were performed before and after 8 weeks. Results The statistical analysis of this study revealed there was a significant increase of T-scores post-treatment compared to pre-treatment within group A (P=0.0001; P<0.05), group B (P=0.0001; P<0.05), and group C (P=0.0001), with improvement percentages of 19.59, 34.69 and 50.66% respectively. There was a decrease of pain intensity during activities post-treatment compared to pre-treatment within group A (P=0.0001; P<0.05), group B (P=0.0001; P<0.05) and group C (P=0.0001), with improvement percentages of 41.28, 54.39 and 70.09% respectively. Conclusions Class IV laser therapy and Pilates exercises are useful therapeutic modalities to increase bone mineral density and decrease pain in patients with osteoporosis, but combining them is more effective than using them separately.

Abstract
[Purpose] To investigate the efficacy of the multi-wave locked system laser therapy on
the regeneration of peripheral nerve injuries by evaluating the functional,
electrophysiological, and morphological changes of the crushed sciatic nerve in Wistar
rats. [Materials and Methods] Sixty male Wistar rats (200–250 g) were randomly assigned to
control negative, control positive, or laser groups and subjected to no laser therapy or
crushing, to crushing without laser therapy, or crushing followed by multi-wave locked
system laser therapy five times/week for four weeks (power=1 W, energy
density=10 J/cm2, total energy=100 J), respectively. Functional,
electrophysiological, and morphometric analyses were performed before and 7, 15, 21, and
28 days after crushing. The sciatic functional index, compound motor action potential
amplitude, motor nerve conduction velocity, and nerve and myelin sheath diameters were
measured. [Results] The sciatic functional index value decreased significantly, while the
compound motor action potential amplitude, motor nerve conduction velocity, nerve
diameter, and myelin sheath diameter increased significantly in the laser group
post-treatment compared to the values in the control groups. [Conclusion] Multi-wave
locked system laser therapy was effective in accelerating the regeneration of crushed
sciatic nerves in Wistar rats.

Abstract
Raynaud's phenomenon (RP) is an episodic vasospasm of the peripheral arteries caused by an exaggerated reaction to cold temperature or emotional stress. Restoring the angiogenesis capability of the acral lesional skin is a critical strategy to treat RP. Local injection of botulinum toxin-A (BTX-A) has also been reported for treatment of RP. However, since the exact mechanisms of BTX-A action are still unclear, its administration for treatment of RP is not widely used. In the present study, BTX-A was found to promote angiogenesis and relieve RP in the patient. To elucidate its mechanisms against angiogenesis, BTX-A was used to treat human umbilical vein endothelial cells (HUVECs), one of the most popular in vitro models of angiogenesis, and RNA sequencing was used to investigate differentially expressed genes. A total of 413 genes were upregulated, and 1634 were downregulated, with fold-changes >2.0 in HUVECs treated with BTX-A. Gene ontology annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis showed BTX-A affected expression of angiogenesis-associated, angiogenesis-associated signaling pathway-related, metabolic pathway, and epigenetic regulation-related genes. These results demonstrate potential biomarkers of BTX-A action, thereby providing potential therapeutic mechanism(s) by which BTX-A relieves RP symptoms.

Abstract
BACKGROUND Multiwave locked system (MLS) laser therapy utilizes the synchronized emission of an 808 nm continuous laser and a 905 nm pulsed laser. It is postulated that MLS enables greater penetration and therapeutic benefit than single-wavelength low-level laser therapy (LLLT). OBJECTIVE The aim of this research was to evaluate the efficacies of MLS laser therapy and the 830 nm laser in the treatment of patients with chronic neck pain (CNP). MATERIALS AND METHODS Seventy-five patients with CNP (mean age 46.28 ± 5.89, weight 83.78 ± 5.65 kg, height 1.72 ± 4.96 m, and duration of illness of 5.98 ± 1.44 months). They were randomized into three groups. Group I received MLS laser therapy and exercises, Group II received LLLT and exercises, and Group III received placebo laser therapy plus exercises (PL + EX). Neck pain levels and neck function were measured using the visual analogue scale (VAS) and neck disability index (NDI), respectively. RESULTS Both VAS and NDI were significantly reduced post-treatment for all treatment groups. After 6 weeks of treatment, MLS plus exercise showed a significantly greater decrease in pain and disability scores {Δ VAS (6.68) and Δ NDI (39.84)} compared to both LLLT plus exercise group {Δ VAS (5.72) and Δ NDI (37.88)} and PL + EX {Δ VAS (4.84) and Δ NDI (36.68)}. CONCLUSIONS MLS laser therapy in conjunction with exercises decreased pain and increased functional activity following 6 months of therapy. MLS laser therapy in combination with exercises is a more effective therapy for CNP compared to exercise plus LLLT or exercise alone.

Raynaud's phenomenon: new aspects of pathogenesis and the role of nailfold videocapillaroscopy. Reumatologia 2015; 53:87-93.

Abstract
Raynaud's phenomenon (RP) refers to paroxysmal pallor or cyanosis of the digits of the hands or feet and, infrequently, the tips of the nose or ears (acral parts) owing to cold-induced vasoconstriction of the digital arteries, precapillary arterioles, and cutaneous arteriovenous shunts. Raynaud's phenomenon reflects an exaggeration of normal central and local vasomotor responses to cold or emotion. Raynaud's phenomenon has been classified as primary or secondary, depending on whether it occurs as an isolated condition or is associated mainly with a connective tissue disease. Dysregulation of autonomic and sensitive nerve fibers, functional and structural vessel changes, and intravascular alterations can be observed in the pathogenesis of RP. Nailfold videocapillaroscopy (NVC) is the best non-invasive and repetitive diagnostic technique for detecting morpho-functional changes in the microcirculation. Nailfold videocapillaroscopy is accepted in early diagnosis and monitoring of primary and secondary RP.
