Effects of exosomes from mesenchymal stem cells on functional recovery of a patient with total radial nerve injury: A pilot study.

BACKGROUND: Peripheral nerve injury can result in significant clinical complications that have uncertain prognoses. Currently, there is a lack of effective pharmacological interventions for nerve damage, despite the existence of several small compounds, peptides, hormones, and growth factors that have been suggested as potential enhancers of neuron regeneration. Despite the objective of achieving full functional restoration by surgical intervention, the persistent challenge of inadequate functional recovery remains a significant concern in the context of peripheral nerve injuries. AIM: To examine the impact of exosomes on the process of functional recovery following a complete radial nerve damage. METHODS: A male individual, aged 24, who is right-hand dominant and an immigrant, arrived with an injury caused by a knife assault. The cut is located on the left arm, specifically below the elbow. The neurological examination and electrodiagnostic testing reveal evidence of left radial nerve damage. The sural autograft was utilized for repair, followed by the application of 1 mL of mesenchymal stem cell-derived exosome, comprising 5 billion microvesicles. This exosome was split into four equal volumes of 0.25 mL each and delivered microsurgically to both the proximal and distal stumps using the subepineural pathway. The patient was subjected to a period of 180 d during which they had neurological examination and electrodiagnostic testing. RESULTS: The duration of the patient's follow-up period was 180 d. An increasing Tinel's sign and sensory-motor recovery were detected even at the 10th wk following nerve grafting. Upon the conclusion of the 6-mo post-treatment period, an evaluation was conducted to measure the extent of improvement in motor and sensory functions of the nerve. This assessment was based on the British Medical Research Council scale and the Mackinnon-Dellon scale. The results indicated that the level of improvement in motor function was classified as M5, denoting an excellent outcome. Additionally, the level of improvement in sensory function was classified as S3+, indicating a good outcome. It is noteworthy that these assessments were conducted in the absence of physical therapy. At the 10th wk post-injury, despite the persistence of substantial axonal damage, the nerve exhibited indications of nerve re-innervation as evidenced by control electromyography (EMG). In contrast to the preceding. EMG analysis revealed a significant electrophysiological enhancement in the EMG conducted at the 6th-mo follow-up, indicating ongoing regeneration. CONCLUSION: Enhanced comprehension of the neurobiological ramifications associated with peripheral nerve damage, as well as the experimental and therapy approaches delineated in this investigation, holds the potential to catalyze future clinical progress.

Consensus recommendations for botulinum toxin injections in the spasticity management of children with cerebral palsy during COVID-19 outbreak

Spasticity is the most common motor disturbance in cerebral palsy (CP). Lockdown in the COVID-19 outbreak has profoundly changed daily routines, and similarly caused the suspension of spasticity treatment plans. Besides, the delay in botulinum toxin (BoNT) injection, which is important in the management of focal spasticity, led to some problems in children. This consensus report includes BoNT injection recommendations in the management of spasticity during the COVID-19 pandemic in children with CP. In order to develop the consensus report, physical medicine and rehabilitation (PMR) specialists experienced in the field of pediatric rehabilitation and BoNT injections were invited by Pediatric Rehabilitation Association. Items were prepared and adapted to the Delphi technique by PMR specialists. Then they were asked to the physicians experienced in BoNT injections (PMR specialist, pediatric orthopedists, and pediatric neurologists) or COVID-19 (pediatric infectious disease, adult infectious disease). In conclusion, the experts agree that conservative management approaches for spasticity may be the initial steps before BoNT injections. BoNT injections can be administered to children with CP with appropriate indications and with necessary precautions during the pandemic.

Tai Chi vs. combined exercise prescription: A comparison of their effects on factors related to falls.

BACKGROUND: Regular exercise training is one of the core components of multifactorial fall-prevention programs. OBJECTIVE: To compare the effect of Tai Chi and combined exercise prescription that consists of three main components of an exercise prescription on static balance, dynamic balance, fear of falling and mood. METHODS: Sixty older adults aged 55-76 were randomly assigned to Group 1 (Tai Chi exercise) or Group 2 (combined exercise prescription). Exercise was performed three times a week over a period of 12 weeks. Single Leg-Stance-Eyes Open (SLS-EO), Single Leg-Stance Eyes Closed (SLS-EC), computerized balance measurements, the Timed Up and Go (TUG) test, Berg Balance Scale (BBS), the Survey of Activities and Fear of Falling in the elderly (SAFFE), the Geriatric Depression Scale (GDS), and the Beck Depression Scale (BDS) were assessed before and after the final training session. RESULTS: Both exercise groups yielded better results in dynamic balance assessments (TUG and BBS) at the 12th week (p< 0.05). Group 1 also showed significant improvements in the measurements of SLS-EO, SLS-EC, SAFFE, GDS, and BDS during the post-intervention period (all p< 0.05). When the groups were compared, a significant difference was found between groups in favor of Group 1 in terms of the SLS-EO and SAFFE (p< 0.05). CONCLUSIONS: It can be concluded that Tai Chi may be a more successful exercise intervention for factors-related to falls in older people.

Simultaneous bilateral ganglion cysts of the anterior cruciate ligaments.

Intra-articular ganglion cysts of the anterior cruciate ligament (ACL) are rare, and bilateral ganglion cysts are even rarer. These cysts may cause intermittent or chronic nonspecific knee discomfort. Although three cases of bilateral ganglion cysts have been reported in the literature, the knees were not simultaneously affected in those cases. Herein, we report the case of a 56-year-old woman who presented with simultaneous bilateral ganglion cysts of the ACL that were symptomatic. She was successfully treated with arthroscopic resection and debridement. We also present a brief review of the literature, highlighting the aetiology, diagnosis and management of ganglion cysts of the ACL. To the best of our knowledge, this is the first report of simultaneous bilateral intra-articular ganglion cysts of the ACL.

Simultaneous and spontaneous bilateral quadriceps tendons rupture.

Simultaneous and spontaneous bilateral quadriceps tendon rupture is an uncommon injury that is usually seen in association with multiple medical conditions and some medications. We report a case of simultaneous and spontaneous bilateral quadriceps tendon rupture that may be related to the long-term use of a statin.

Transforaminal epidural steroid injection via a preganglionic approach for the treatment of lumbar radicular pain.

AIM: To evaluate the effectiveness of transforaminal epidural steroid injection (TFESI) for lumbar radiculopathy with respect to effect of injection levels, gender, and age group. MATERIAL AND METHODS: Hundred-fifty-three consecutive patients who underwent to lumbar TFESI were enrolled. The outcomes were measured by using a visual numeric scale (VNS), NASS and EQ-5D. The relationship between possible outcome predictors and the therapeutic effect were evaluated. RESULTS: All the patients completed the 2nd year follow-up visits. Significant differences were observed between the pre-procedure and post-procedure VNSs, NASS patients' satisfactions scores and EQ-5D (P < 0.01) except 1st and 2nd year follow-up (P=0.12, P=0.27and P=0.19 respectively). Gender (higher in female patients) showed significant effect to pre-procedure VNS (P=0.04). An increase in the level number was significantly associated with an increase in the 6th month (P=0.005, P=0.004 respectively) and the 1st year (P=0.05, P=0.029 respectively) NASS and EQ-5D. No complication was occurred except discitis in two chronic renal failure patients. CONCLUSION: Especially in the patients with severe co-morbidities TFESI is an option to provide higher life quality. The clinical course of the success of the TFESI decreases in one year and becomes stable thereafter. In the patients with immune deficiency, the practitioners should always be aware for an infectious complication.

Comparison of effectiveness of facet joint injection and radiofrequency denervation in chronic low back pain.

AIM: The study was conducted to compare the clinical effectiveness of FJ injections (FJI) and FJ radiofrequency (FJRF) denervation in patients with chronic low back pain. MATERIAL AND METHODS: This study included 100 patients; 50 in FJI 50 in FJRF group. VNS, NASS and EQ-5D were used to evaluate the outcomes. All outcome assessments were performed at baseline, 3 months, 6 months and 12 months. RESULTS: FJI in early post-op but FJRF in 1st, 6th and 12th month VNS showed better results (p < 0.001). There was no significant difference in the 1st (p=1) and 6th month (p=0.13) but in 12th month (p=0.04) in NASS. Increase in level number showed positive effect in NASS in FJRF group (p=0.018) but no effect in FJI group (p=0.823) in the 12th month follow-up. There was no significant difference with respect to 1st month (p=0.17), 6th month (p=0.22) and 12th month (p=0.11) post-procedure follow-ups in EQ-5D. At the short term FJI was more effective than FJRF however in midterm follow-up FJRF had more satisfying results than FJRF. CONCLUSION: To our knowledge, the first choice should be the FJI and if pain reoccurs after a period of time or injection is not effective, RF procedure should be used for the treatment of chronic lumbar pain.

The role of kinesiotaping combined with botulinum toxin to reduce plantar flexors spasticity after stroke.

PURPOSE: To evaluate the effect of kinesiotaping as an adjuvant therapy to botulinum toxin A (BTX-A) injection in lower extremity spasticity. METHODS: This is a single-center, randomized, and double-blind study. Twenty hemiplegic patients with spastic equinus foot were enrolled into the study and randomized into 2 groups. The first group (n=10) received BTX-A injection and kinesiotaping, and the second group (n=10) received BTX-A injection and sham-taping. Clinical assessment was done before injection and at 2 weeks and 1, 3, and 6 months. Outcome measures were modified Ashworth scale (MAS), passive ankle dorsiflexion, gait velocity, and step length. RESULTS: Improvement was recorded in both kinesiotaping and sham groups for all outcome variables. No significant difference was found between groups other than passive range of motion (ROM), which was found to have increased more in the kinesiotaping group at 2 weeks. CONCLUSION: There is no clear benefit in adjuvant kinesiotaping application with botulinum toxin for correction of spastic equinus in stroke.

The effect of an ankle-foot orthosis on temporal spatial parameters and asymmetry of gait in hemiparetic patients.

OBJECTIVE: To investigate the effect of an ankle-foot orthosis (AFO) on certain walking parameters in patients with hemiplegia. DESIGN: Retrospective study. SETTING: Gait and Motion Analysis Laboratory at MossRehab. PARTICIPANTS: A total of 1150 records of patients with stroke who were referred to the Gait and Motion Analysis Laboratory between 2000 and 2008 for an evaluation of their walking. Of this group, 217 patients wore braces at the time of the gait evaluation and were selected for a more in-depth review. Among these patients, 42 records were selected because of the existence of available data from temporal spatial analysis meeting 2 conditions: walking with bare feet and walking with an AFO during the same visit. METHODS AND MAIN OUTCOME MEASUREMENTS: Under both conditions, temporal spatial parameters of gait, including self-selected velocity, cadence, stance time, swing time, double support time, step length, and width of the base of support, were assessed by the use of an electronic gait mat (Gait Mat II, EQ Inc.) originally designed in the Moss Rehabilitation Engineering Center. RESULTS: Walking velocity, cadence, percent stance, double support, and step length significantly increased, whereas affected side percent swing and width of the base of support decreased when patients used an AFO. Symmetries of stance time (P = .0001) and step length (P = .002) improved as well when patients used an AFO compared with walking barefoot. CONCLUSION: In this sample of patients with stroke, the use of an AFO improved the symmetry of several of the temporal spatial parameters of gait, and consequently, the gait pattern of these hemiparetic patients was enhanced.

[Orthotic management in cerebral palsy]. / Beyin felcinde ortez uygulamalari.

Children with cerebral palsy (CP) may have many musculoskeletal deformities depending on the type of CP. These deformities may result from (i) lack of motor control, (ii) abnormal biomechanical alignment, (iii) impairment in timing of muscle activation, (iv) impairment in normal agonist/antagonist muscle balance, (v) lack of power generation, and (vi) balance disorder. Rehabilitation, orthopedic surgical intervention, and additional orthotic management can prevent and correct these deformities. In this review, mainly lower extremity orthoses are described, with brief explanation on upper and spinal orthotic applications.

A case report: pregnancy-induced severe osteoporosis with eight vertebral fractures.

Osteoporosis associated with pregnancy and lactation is a rare condition. The prevalence, etiology and its pathogenesis is unknown. It causes one or more vertebral fractures with severe, prolonged back pain and height loss in affected women. Majority of the cases are seen in the third trimester or just after delivery in primagravid women. In this case report, a 30-year-old woman who had severe pregnancy-induced osteoporosis with 8 vertebral fractures was presented. During last month of her first pregnancy she had moderate back pain. After delivery, the back pain has gotten worse. The radiological examinations have shown that there was 50% in T6, T8 and T10; 30% in L2; 20% in L1 height loss and biconcave vertebral images in L3-5. In the bone mineral density, L2-4 T score was -4.7 and total femoral T score was -3.1. There was no abnormality in the laboratory findings except mild elevation in alkaline phosphates. Although pregnancy-associated osteoporosis is a rare condition, when pain occurs in the last trimester or early postpartum period, it should be considered in differential diagnosis.

Relationship between arm span and height in postmenopausal osteoporotic women.

Osteoporosis is a progressive systemic skeletal disease characterized by low bone density and microarchitectural deterioration of the bone. A minimum 3-cm difference between arm span and height makes up one of the criteria for suspecting osteoporosis. Therefore, it is easy to determine osteoporotic women by measuring the proportion of height to the arm span. The purposes of this study are to assess the relationship between arm span and height and to compare them in postmenopausal and young healthy women. This was a randomized-controlled, prospective study. There were two groups in this study. Group I included 70 postmenopausal osteoporotic women and group II had 70 healthy young women. Height, weight and arm span of the individuals were measured in all subjects. Bone mineral density and radiological examination of spine were also evaluated. Mean age of postmenopausal women was 64.4 +/- 8.6 years and it was 27.3 +/- 3.5 years in young healthy women. Mean height was 152 +/- 5.1 and 161.5 +/- 5.9 cm in group I and II, respectively. Mean arm span length was 159.6 +/- 6.3 cm in postmenopausal women and 163.5 +/- 6 cm in young healthy women. Mean arm span-height difference was significantly higher in postmenopausal women when compared to healthy young women (7.7 +/- 3.6 and 2 +/- 2.9 cm, respectively, P < 0.001). We suggest that arm span measurements can be used in the estimation of youth height and age-related loss in stature in postmenopausal women.

Early effect of nasal salmon calcitonin on the bone marker Crosslaps.

The aim of this study was to investigate the early effect of nasal salmon calcitonin on a bone-resorption marker, "Crosslaps", in postmenopausal osteoporotic women. In this randomized, single-blind and placebo-controlled study we included 78 postmenopausal women with osteoporosis, between 45 and 65 years of age, with at least 5 years duration of menopause. Patients were randomly divided into two groups, the treatment and the placebo groups. Patients in the treatment group were given 100 IU day(-1) nasal salmon calcitonin, 1,000 mg day(-1) elemental calcium, and 400 IU day(-1) vitamin D. Patients in the placebo group took only 1,000 mg day(-1) elemental calcium, and 400 IU day(-1) vitamin D. The outcome measurements were urinary deoxypyridinoline, serum alkaline phosphatase, osteocalcin, and Crosslaps. The treatment group consisted of 39 patients whose mean age was 60.4 +/- 6 years and the placebo group included 39 patients with a mean age of 60.5 +/- 4.9 years. There was no significant difference between two groups in terms of demographic characteristics. The results of bone marker measurements were analyzed statistically. Crosslaps levels in the treatment group were significantly lower (P < 0.05) than in the placebo group. Other bone marker levels at the end of the study were not significantly lower (P > 0.05) than those at baseline in both treatment and placebo groups, however. Salmon calcitonin affects bone turnover within a few months and bone-resorption markers such as Crosslaps can be used to monitor the effect of nasal salmon calcitonin in the early phase of treatment for postmenopausal osteoporosis.

Bilateral tibial stress fracture in a young man due to hypercalciuric osteoporosis: a case report.

Osteoporosis is commonly thought of as a disease of postmenopausal women, and older men have a lower risk of fracture than women. A stress fracture is an overuse injury and an important cause of disability in the athletic population. Presented here is a 30-year-old healthy man with pain on the anterior surface of the bilateral tibia. He did not communicate any trauma or overuse activity. The neurologic and locomotor system examinations were normal. Radiological examinations revealed tibial stress fractures in both left and right tibia and he had low bone mineral density. Routine hematological tests, bone resorption and formation markers were normal, except for hypercalciuria. After analyzing the results of these tests, the patient was diagnosed with bilateral tibial stress fractures due to hypercalciuric secondary osteoporosis. Osteoporosis should be considered in the differential diagnosis of atraumatic insufficiency fractures, especially in young healthy adults.

Hypermobility in women with fibromyalgia syndrome.

The purpose of this study was to evaluate the relationship between hypermobility and fibromyalgia syndrome (FS) in women. Ninety-three women with FS who met the American College of Rheumatology criteria for FS and 58 healthy women without FS were included in this study. All women were examined for hypermobility by blinded observers using the Beighton criteria. The mean age was 43.5+/-9.9 (21-68) and 40.2+/-11.1 (21-63) years in the FS and control groups, respectively, and the two groups were statistically similar (p>0.05). The mean Beighton total score was 4.7+/-2.1 and 2.9+/-2.4 in the FS and control groups, respectively (p<0.0001). The frequency of joint hypermobility was 64.2% in the FS group and 22% in the control group. In accordance with the Beighton criteria (p<0.05), we found that the joint hypermobility ratio was significantly higher in patients with FS than in subjects without FS. Additionally, we evaluated the correlation between the total Beighton score and the age and number of trigger points. There were negative correlations between the total Beighton score and the age (r=-0.42, p<0.001) and number of trigger points (r=-0.24, p=0.03) in all patients. Hypermobility syndrome is more common in women with FS than in those in the control group. Therefore, the relationship between hypermobility and FS should be taken into consideration in the diagnosis and follow-up of women, especially those with widespread pain.

Evaluation of the neurosensory function of the medial meniscus in humans.

PURPOSE: Menisci are known to have receptors mainly concentrated at the anterior and posterior horns. Although they are purported to send afferent impulses to the central nervous system, this function has not been thoroughly evaluated. The purpose of the study was to investigate whether stimulation of the menisci initiates a cortical response. The reaction of the end organ to the reflex arc is also evaluated. TYPE OF STUDY: Prospective case series. METHODS: Fourteen patients with normal medial menisci were included in the study. Different parts of the knee joint (the posterior horn and the body of the medial meniscus, the medial femoral condyle, the capsule, and the joint space) were electrically stimulated by a probe during arthroscopy. The cortical response was monitored with somatosensory-evoked potentials (SEPs). The compound muscle action potentials (CMAPs) of the semimembranosus, quadriceps, and biceps femoris muscles were also monitored with electroneuromyography (ENMG). RESULTS: Among the stimulated parts, only the posterior horn of the meniscus produced cortical responses. No response was obtained with stimulation of the medial femoral condyle, the body of the medial meniscus, the capsule, or the joint space. Stimulation of the posterior horn of the medial meniscus produced a measurable amount of CMAP latency for the semimembranosus muscle, but not for the quadriceps and biceps femoris muscles. CONCLUSIONS: Stimulation of the posterior horn of the medial meniscus produces reproducible cortical SEPs and results in ENMG-verified response of the semimembranosus muscle where no response of the semimembranosus muscle is detected with stimulation of the other parts of the knee. CLINICAL RELEVANCE: The knowledge that only the horns of the medial meniscus have mechanoreceptors in the medial compartment of the knee helps to understand patients' signs and symptoms in medial compartment disease.

Sensorial donor site morbidity after saphenous neurocutaneous flap.

Neurocutaneous flaps based on the arterial network around the superficial sensory nerves are popular in soft tissue coverage of the lower extremities, and are usually preferred in reconstruction of the lower leg and foot. Although sacrifice of sensory cutaneous nerves is mentioned as one of their major disadvantages to our knowledge the morbidity in the foot and at the donor site has not been properly investigated. We investigated sensorial morbidity in the foot and at the donor site caused by raising a saphenous neurocutaneous flap in 14 patients by using static two-point discrimination test, Semmes-Weinstein monofilament test, vibration test, and by measuring somatosensory evoked potentials in the twelfth postoperative month. Our results suggest that sensory recovery is good and protective sensation is gained in most patients.

A method for determining the grade of osteoporosis based on risk factors in postmenopausal women.

The aim of this study was to determine whether the probability of osteoporosis and osteopenia was affected by the risk factors, physical examination findings, or radiological investigations such as spinal X-rays in postmenopausal women. We assessed risk factors such as use of hormone replacement therapy, physical activity level, calcium intake, smoking, caffeine consumption, long-term immobilization, previous history of fracture, family history of fracture, presence of certain systemic diseases (hyperthyroidism or hyperparathyroidism), or use of medications (corticosteroids or others), physical examinations, and presence of vertebral fractures on spinal X-rays. Patients' bone mineral density (BMD) was evaluated using dual energy X-ray absorptiometry (DXA) in the lumbar spine, and we compared the risk factors between osteopenic and osteoporotic women according to DXA. We evaluated 235 postmenopausal women who attended our osteoporosis outpatient clinic. Those patients were divided into two groups as either osteopenic (n = 67, mean age: 63.1 years) or osteoporotic (n = 168, mean age: 66.2 years) according to WHO criteria. The lumbar spinal (L1-L2) T-score values were -1.5 +/- 0.6 and -3.1 +/- 0.6 in osteopenic and osteoporotic groups, respectively. There were significant differences between the two groups in terms of mean age and lumbar BMD (p = 0.009 and p < 0.001, respectively). We also observed that vertebral tenderness on palpation, back pain, and existing vertebral fracture (fx) were significantly different between the osteopenic and osteoporotic groups (p < 0.05). As a result of the statistical analysis, we found an equation to determine osteopenic and osteoporotic women by using those four factors (age, vertebral tenderness on palpation, back pain, and existing vertebral fx) in multivariate stepwise logistic regression. The equation is as follows: Y (DXA) = -2.9024 + 0.044 (age in year) + 0.819 (vertebral fx) + 0.877 (pain) + 1.136 (vertebral tenderness). We can estimate whether a postmenopausal woman is osteopenic or osteoporotic based on these risk factors by using the stepwise logistic regression equation.

Quality of life in patients with fibromyalgia syndrome and rheumatoid arthritis.

The objective of this study was to determine and compare the quality of life (QOL) of patients with fibromyalgia syndrome (FS) and rheumatoid arthritis (RA) and to assess patients' psychological and functional status in each group. This prospective study included 62 female FS patients and 60 female RA patients diagnosed by the American College of Rheumatology criteria. The Turkish translations of the Arthritis Impact Measurement Scale II (AIMS II) and Beck Depression Index (BDI) were given to all of the patients and they were asked to complete the two questionnaires. The scores of AIMS II, pain, and QOL were evaluated in the FS and RA groups. There were no statistically significant differences between the FS and RA groups (p>0.05) in terms of QOL. The affect subgroup scores of the AIMS II and BDI were highly correlated in the FS and RA groups (p<0.002, r=0.85 and p<0.05, r=0.80, respectively). The results show that the QOL is negatively but similarly affected in FS and RA groups.
