Adipose tissue derived stromal cells (ADSCs) play a crucial role in research and applications of regenerative medicine because they can be rapidly isolated in high quantities. Nonetheless, their purity, pluripotency, differentiation capacity, and stem cell marker expression might vary greatly depending on technique and tools used for extraction and harvesting. There are two methods described in the literature for isolating regenerative cells from adipose tissue. The first technique is enzymatic digestion, which utilizes many enzymes to remove stem cells from the tissue they reside in. The second method involves separating the concentrated adipose tissue using non-enzymatic, mechanical separation methods. ADSCs are isolated from the stromal-vascular fraction (SVF) of processed lipoaspirate, which is the lipoaspirate's aqueous portion. The purpose of this work was to evaluate a unique device 'microlyzer' for generating SVF from adipose tissue using a mechanical technique that required minimal intervention. The Microlyzer was examined using tissue samples from ten different patients. The cells that were retrieved were characterized in terms of their cell survival, phenotype, proliferation capacity, and differentiation potential. The number of progenitor cells extracted only from the microlyzed tissue was in comparable amount to the number of progenitor cells acquired by the gold standard enzymatic approach. The cells that were collected from each group exhibit similar levels of viability as well as proliferation rates. In addition, the differentiation potentials of the cells derived from the microlyzed tissue were investigated, and it was discovered that cells isolated through microlyzer entered the differentiation pathways more quickly and displayed a greater level of marker gene expression than cells isolated by enzymatic methods. These findings suggest that microlyzer, particularly in regeneration investigations, will allow quick and high rate cell separation at the bedside., (© 2023. The Author(s).)

Study Design: Cross-sectional study., Objective: To investigate the role of ultrasonographic measurement of the diaphragm thickness on pulmonary function tests in patients with spinal cord injury (SCI)., Setting: Rehabilitation center in Ankara, Turkey., Methods: A total of 42 patients (34 M, 8 F) with SCI and 20 able-bodied volunteers (8 M, 12 F) were enrolled. Patients with SCI were divided into three groups according to their neurological (injury) levels. All participants underwent ultrasonographic measurements for diaphragm thickness on both sides and spirometric tests for pulmonary functions. The thickness ratio of the diaphragm was also calculated., Results: There were seven patients (5 M, 2 F) in C2-C4 injury group, 14 patients (12 M, 2 F) in C5-T5 group, 21 patients (14 M, 7 F) in T6-L2 group, and 20 able-bodied volunteers (8 M, 12 F). The diaphragms of C2-C4 group were thicker than those of the controls at end-inspirium on the right side (2.7 ± 0.7 mm vs. 2.0 ± 0.5 mm; p = 0.035). The thickness ratios of C2-C4 group were lower than those of controls on the right (0.8 ± 0.4 vs. 1.5 ± 0.5; p = 0.005) and left (0.8 ± 0.5 vs. 1.6 ± 0.7; p = 0.003) sides. For all the pulmonary function tests (except for FEV1/FVC); patients with SCI had worse results than controls; and among the SCI groups, the higher the injury level, the worse the results., Conclusion: Although patients with high-level SCI had worse pulmonary function tests and decreased the contractile capacity of the diaphragm, they had thicker diaphragm muscles than controls. This may have been due to the compensatory effect of the diaphragm (performing its maximum contraction capacity and increasing frequency of inspiration).

We report the case of a 40-year-old female patient presenting with resistant heel pain attributable to plantar fascia rupture. She was treated with ultrasound-guided platelet-rich plasma injection, and her pain was decreased. Additionally, ultrasound was useful for diagnosis, intervention and follow-up of the patient.

Objectives: The primary aim of this study was to compare the effects of aquatic exercises and land-based exercises on spasticity, quality of life, and motor function in children with cerebral palsy (CP). The secondary aim was to assess the morphology of spastic muscle using ultrasonography., Patients and Methods: Thirty-two children (17 boys, 15 girls; mean age 9.7±2.7 years; range 4 to 17 years) with CP were enrolled in this study. The patients were randomly assigned to two groups to receive 30 sessions of an aquatic or a land-based exercise program. The patients were assessed for the impairment level, functional measures, and quality of life before and after therapy. Ultrasonographic assessment of spastic gastrocnemius muscle was also performed., Results: Both group showed significant improvements in most functional outcome measures. There were no significant differences in the percentage changes of the scores for functional outcome measures between the two groups. However, aquatic exercise produced a higher improvement in quality of life scores than the land-based exercises. Post-treatment ultrasonographic assessment of spastic gastrocnemius muscle showed a significant improvement in the compressibility ratio in the aquatic exercise group. The modified Ashworth Scale score of spastic gastrocnemius muscle in patients with CP showed a negative and weak-to-moderate correlation with the compressibility ratio based on the ultrasonographic evaluation., Conclusion: Our study results suggest that the aquatic exercises are as effective as land-based exercises for spasticity management and motor function improvement in children with CP. Aquatic exercise can result in a higher level of improvement in quality of life scores than the land- based exercises. Ultrasonographic muscle compressibility ratio may be used to evaluate muscle elasticity in children with CP., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article.

Aim: The use of biomarkers of osteoarthritis (OA) have potential for early diagnosis, evaluation of disease severity and monitoring treatment. Serum and synovial fluid YKL-40 levels are increased in severe knee OA. Pulsed electromagnetic field (PEMF) therapy is a novel treatment method for OA. However, studies evaluating the PEMF therapy in treatment of knee OA revealed conflicting results. This study was conducted to objectively assess the effect of PEMF therapy in patients with knee OA, by using ultrasonographic measurements and a novel biomarker, YKL-40., Methods: Forty patients were randomized into two treatment groups. Both groups received conventional physical therapy, while Group 1 received additional PEMF therapy. The patients were asked to rate their pain on a visual analogue scale (VAS) and complete a Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire. Serum YKL-40 levels were measured, and knee effusion and cartilage degeneration level were evaluated with ultrasonography before and after treatment., Results: Pre-treatment YKL-40 level was correlated with WOMAC pain subscale (P = 0.032, r = 0.339). VAS and WOMAC scores significantly improved in both treatment groups (P < 0.05). The effusion in the right knee significantly decreased in Group 1. The change in YKL-40 level was not correlated with the change in VAS, WOMAC scores and knee effusion., Conclusion: This study revealed that adjuvant PEMF therapy has no additional effect on pain in patients with knee OA. Serum YKL-40 level seems to be unuseful for monitoring the treatment in knee OA., (© 2015 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.)

Background: Inadequate relief of postthoracotomy pain is a major reason of increased occurrence of postoperative complications. We aimed to investigate and compare the effects of transcutaneous electrical nerve stimulation (TENS) and paravertebral block (PVB) to relieve pain after thoracotomy procedures., Materials and Methods: We studied 40 patients who underwent thoracotomy. Patients were randomly allocated to receive either PVB (group P, n = 20) or TENS (group T, n = 20) for postoperative pain. The electrodes of TENS were placed 2 cm under and 2 cm over the thoracotomy cut on both posterior and anterior sides. The surgeon inserted paravertebral catheters using direct vision at the end of the surgery. A patient-controlled analgesia (PCA) device was connected to all patients. Visual analog scales, patient demand, and consumption of tramadol were evaluated postoperatively., Results: Mean visual analog scale (VAS) values were significantly lower in group P for all time points. The patients in group P needed lower amounts of opioid (tramadol) and the difference was statistically significant (258.4 ± 13.52 mg vs. 314.4 ± 8.65 mg, p = 0.005). In addition, the number of demand attempts recorded from the PCA device was significantly lower in group P (14.95 ± 13.64 vs. 26.7 ± 17.34, respectively and p < 0.001)., Conclusion: TENS has beneficial effects for pain relief after thoracotomy, without any side effects; however, it cannot provide sufficient pain relief when compared with PVB., (Georg Thieme Verlag KG Stuttgart · New York.)

Fibromyalgia may present with widespread pain and tenderness, fatigue, anxiety, and depression and is associated with a low pain threshold. The etiology of fibromyalgia is yet to be ascertained, although both genetic and environmental factors may play a role in the susceptibility of patients to fibromyalgia. Various genetic variations have been investigated to explain fibromyalgia susceptibility and differences in pain sensitivity, pain threshold, and tolerance. The A118G rs1799971 polymorphism in the opioid receptor μ1 gene (OPRM1) is one of the candidate genes. We hypothesized that the OPRM1 polymorphism may play a role in fibromyalgia susceptibility and impact the pain intensity and pain-related symptoms in fibromyalgia patients. This study comprised of 108 patients with fibromyalgia and 100 healthy controls. Overall, the 118G allele frequency was 16.3 % and was significantly lower in patients with fibromyalgia than in the control group (13.9 and 19 %, respectively). No difference was observed between fibromyalgia patients with and without the A118G allele with regard to the Beck Depression Inventory, widespread pain index, symptom severity, and Fibromyalgia Impact Questionnaire scores. All body parts of patients with fibromyalgia demonstrated lower pressure pain thresholds (PPT) compared to controls. The PPTs were higher in the 118 A/A genotype carrier fibromyalgia patients than in 118*/G carriers; however, the differences were not significant. As the A118G polymorphism frequency was lower in fibromyalgia patients, this polymorphism may exert a protective effect against fibromyalgia in Turkish women. However, the OPRM1 polymorphism does not have a significant effect on pressure pain and fibromyalgia severity.

Metachromatic leukodystrophy (MLD) is a lysosomal storage disease characterized by demyelination of the peripheral and central nerves. Patients with MLD can present with gait disturbances, progressive spastic quadriparesis, diffuse muscle atrophy, and areflexia attributable to central or peripheral nerve involvements. The rehabilitation of patients with MLD generally focuses on gait disturbances, balance impairments, and muscle weaknesses. Here, we present a case of MLD in which virtual reality (VR) training was used as an adjunctive therapy. We also discuss the complementary role of VR therapy, which was successfully integrated with a conventional rehabilitation program for a young patient with MLD who had impaired balance and gait. After completion of the integrated rehabilitation program, the patient demonstrated improvements in functional independency, mobility, walking speed, and balance. His total Functional Independence Measure score increased from 97 to 109, 6-minute walk test increased from 342 to 396 m, 10-minute walk test decreased from 11 to 7 seconds, and Berg Balance Scale score increased from 38 to 42 points. Moreover, 6 weeks after completion of the therapy, these improvements were sustained for the most part. Adding VR to a conventional rehabilitation program is an emerging trend in neurologic rehabilitation. Our patient with MLD demonstrated considerable improvements with a high level of enjoyment and satisfaction., (Copyright © 2014 American Academy of Physical Medicine and Rehabilitation.

Objectives: This study aims to investigate the effect of acromioclavicular joint (ACJ) degeneration on orthopedic shoulder tests (OST) and to determine complementary role of ACJ injections in the treatment of subacromial shoulder impingements., Patients and Methods: At a secondary care center, 62 patients (56 females, 6 males; mean age 55.8±9.3 years; range 35 to 74 years) with the clinical and radiological diagnosis of shoulder impingement syndrome were enrolled to the study. Two injections were applied to ACJ and subacromial space. Patients were assessed through OSTs (Neer, Hawkins-Kennedy, empty can, full can, external rotation resistance, lift-off and cross-body adduction tests) at baseline and after injection to ACJ and subacromial space. Visual analog scale was used for overall pain., Results: Two injections and three sets of OSTs were performed on the patients. A significant difference was found in the all OSTs after ACJ injection (p<0.001). Visual analog scale scores improved significantly following both ACJ and subacromial injections (p<0.001)., Conclusion: Concomitant ACJ diseases should assessed carefully in the patients with rotator cuff lesions, as it may change the type of management approach.

Reported here is a 19-year-old female patient with familial Mediterranean fever who was seen for altered mental status and seizures. She was eventually diagnosed to have posterior reversible leukoencephalopathy syndrome. Although a variety of conditions have been reported in association with this syndrome, to our best notice, this is the second case in whom familial Mediterranean fever and posterior reversible leukoencephalopathy coexists.
