The frequency of sarcopenia in haemophilia patients: Effects on musculoskeletal health and functional performance.

INTRODUCTION: In patients with haemophilia A, chronic arthropathy develops over time as a result of recurrent joint bleeds, which leads to restricted mobility and disability in the affected joints. There are limited studies in the literature evaluating sarcopenia in patients with haemophilia. The present study aims to determine the prevalence of sarcopenia in severe haemophilia-A patients and to evaluate musculoskeletal health and functional performance. METHODS: Thirty haemophilia-A patients and 26 adult male volunteers were enrolled in the study. For detection of sarcopenia, the appendicular skeletal muscle mass (ASM) obtained by bioelectrical impedance analysis (BIA) was divided by height squared (m2 ) to obtain the appendicular skeletal muscle mass index (ASMI) value. The thighs of both lower extremities were measured using the Modified Sonographic Tight Adjustment Ratio (STAR) method, which was obtained by adding the bilateral rectus femoris and vastus intermedius muscle thicknesses measured by ultrasound. Hand and quadriceps muscle strength (MS) were measured with a dynamometer. Physical performance was determined using the walking speed (WS), timed up-and-go test (TUGT), 5-repetition sit-to-stand test (5RSTS), and 6-min walk test (6MWT). Haemophilia Joint Health Score (HJHS) and Haemophilia Early Arthropathy Detection-Ultrasonography (HEAD-US) were also used to assess the musculoskeletal system. RESULTS: According to the modified STAR values calculated based on body mass index, sarcopenia was present in 15 (50%) of 30 patients. However, based on the ASMI-BIA values, sarcopenia was present in only two (6.6%) patients. A weak correlation was found between ASMI and HJHS, HEAD-US, WS, TUGT, and hand MS (left), while a moderate correlation was found with knee MS (right), knee MS (left), and 5RSTS. A strong correlation was found between the modified STAR score and HEAD-US, HJHS, knee MS (left), 5RSTS, TUGT, and WS, while a moderate correlation was found with hand MS (left), hand MS (right), and knee MS (right). CONCLUSION: This study showed muscle loss, joint mobility restrictions, and decreased functional capacity in haemophilia patients and demonstrated the presence of sarcopenia in these patients. The STAR measurement method showed stronger relationships with MS and functional performance values than ASMI measurements in terms of evaluating sarcopenia.

Frequency of idiopathic intracranial hypertension with ultrasound in patients with fibromyalgia: Relation with function, central sensitization, and neuropathic pain.

OBJECTIVE: The purpose of this study was to evaluate the prevalence of idiopathic intracranial hypertension (IIH) in fibromyalgia (FMS) patients by utilizing ultrasound to measure the optic nerve sheath diameter (ONSD), a marker of elevated intracranial pressure and also to investigate the relationship with function, fatigue, quality of life (QOL), central sensitization (CS) and neuropathic pain. METHODS: The study encompassed 80 female FMS patients and 75 healthy controls. Ultrasound was employed to measure the average ONSD in both groups. Conditions potentially elevating intracranial pressure were ruled out following neurological assessments. Pain (via visual analog scale, VAS), function (revised Fibromyalgia Impact Questionnaire, r-FIQ), QOL (Short Form-36, SF-36), fatigue (fatigue severity scale, FACIT), CS (Central Sensitization Scale), and neuropathic pain (Douleur Neuropathique-4) were evaluated. RESULTS: The average ONSD was significantly higher in the patient group than the control group. Patients with ONSD >5.5 mm consistent with IIH were categorized as Group 1 (n = 54, 67.5%), while those with a diameter of 5.5 mm and below-formed Group 2. VAS pain (p = .033) and FIQ-R scores (p = .033) were significantly higher in Group 1 than Group 2. Headache was found more common in Group 1. CONCLUSION: This study unveils a substantial occurrence (67.5%) of IIH in FMS patients, suggesting shared pathophysiological mechanisms contributing to symptoms like fatigue, headache, and cognitive dysfunction. Additionally, these findings implicate heightened functional impairment, CS, headache, and fatigue in FMS patients with IIH.

Comparison of the efficacy of continuous radiofrequency thermocoagulation, pulsed radiofrequency denervation applications, and TENS therapies for lumbar facet syndrome: A single-blind randomized controlled trial.

OBJECTIVES: We aimed to compare the effectiveness of TENS, used in physical therapy departments, and continuous radiofrequency thermocoagulation (CRF) and pulsed radiofrequency denervation (PRF), used in algology departments, in patients with lumbar facet syndrome (LFS). METHODS: Subjects were selected from patients with LFS visiting outpatient clinics of physical therapy and algology departments at Ege University School of Medicine, whose pain was refractory to medical treatment for at least 3 months. Subjects were randomized into 3 groups. A total of 60 patients, with 20 in each group, were enrolled. The first group received CRF, the second group received TENS for 30 minutes a day for 15 days, and the third group received PRF. Patients were assessed at baseline, at the end of the first and sixth months, for a total of three times. RESULTS: Improvements at month 1 and month 6 were found to be statistically significant in all three treatment groups with respect to their pain scores, Oswestry Disability Indexes, hand-floor distance measurements, 20-meter walking times, 6-min walking distances, Beck Depression Inventory, and most of the SF-36 domain scores (p<0.05). A comparison of the treatment groups showed no superiority of any group over the others in any assessment parameters (p>0.05). CONCLUSION: We suggest that it might be more appropriate to use TENS, a non-invasive treatment, before trying more invasive procedures like CRF and PRF in these patients. However, it has been stated that further studies involving a larger patient sample are needed.

The attitudes of Turkish physicians in the treatment of fibromyalgia; is 'Pregabalinophobia' the new reality of pain medicine?

OBJECTIVES: This study aims to determine the treatment preferences of physicians interested in fibromyalgia treatment and to investigate their hesitations about prescribing pregabalin. METHODS: Our survey study was conducted between February 5 and 20, 2021. The survey forms were sent to the known email addresses and phone numbers of 1569 physical medicine and rehabilitation (PMR), algology, and rheumatology physicians. The replies to the surveys were checked for possible resubmissions. The pooled data were evaluated with the SPSS 22.0 statistical package program. Frequency distributions were calculated and presented as n, %. RESULTS: Four hundred and six PMR, rheumatology, and algology specialists fulfilled the study forms. About 59.0% of physicians stated that they prefer duloxetine as the first-line agent of fibromyalgia syndrome (FMS) treatment. Pregabalin was only 6.0% of the physicians' first choice for FMS. About 35.0% of the participating physicians stated that the PMR department should follow up FMS patients. About 44.3% of the participants noted that they refer FMS patients to other departments which interested in FMS treatment and do not want to follow-up FMS patients. About 81% agreed that pregabalin causes addiction. About 36.7% stated that at least 20% of the patients could abuse pregabalin and 97.8% of physicians stated that they were prejudiced about prescribing pregabalin to prisoners. Approximately two of the three physicians experienced an act of violence in their hospital regarding pregabalin prescribing. CONCLUSION: These data showed that the 'Pregabalinophobia' should be accepted. This condition is associated with life safety concerns of the physician not only from unreliability of the drug. It seems that the doctors have valid reasons to develop this prejudice.

Epidermal growth factor enhances spinal fusion: Posterolateral lumbar fusion model on rats.

OBJECTIVE: The aim of this study was to investigate the effects of human recombinant epidermal growth factor (EGF) on posterolateral lumbar fusion in a rat model. METHODS: 36 male Sprague Dawley rats underwent posterolateral fusion at L4-5 level. They were randomly assigned to 3 groups: 1- Sham control group where no local augmentation was made, 2- Local Hydoxyapatite ß-tricalcium phosphate (HA/ß-TCP) augmentation group and 3- Local HA/ß-TCP + EGF augmentation group. Rats were euthanized at 8 weeks post-surgery. 6 rats from each group were selected for manual palpation examination, micro-computed tomography analysis and histologic analysis; and the rest was used for biomechanical analysis. RESULTS: Based on manual palpation, there was no fusion in the sham control group. Fusion rate was 33.3% in the HA/ß-TCP group and 66.7% in the HA/ß-TCP + EGF group (p = 0.085). Micro-CT results revealed that new bone formation was higher in the HA/ß-TCP + EGF group (BV/TV: 40% vs. 65%) (p = 0.004). Histologically newly formed bone tissue was more pronounced in the EGF group and compacted and bridging bone spicules were observed. The median maximum bending moment values were 0.51 Nmm (0.42-0.59), 0.73 Nmm (0.49-0.88) and 0.91 Nmm (0.66-1.03) in the sham control, HA/ß-TCP and HA/ß-TCP + EGF groups, respectively (p = 0.013). The median stiffness values were 1.69 N/mm (1.12-2.18), 1.68 N/mm (1.13-2.74) and 3.10 N/mm (1.66-4.40) as in the previous order (p = 0.087). CONCLUSION: This study demonstrates that EGF enhances posterolateral lumbar fusion in the rat model. EGF in combination with ceramic grafts increased the fusion rates. Our findings may provide insights to further studies, investigating EGF's clinical usage as an alternative fusion enhancer.

Investigation of the effects of semaphorin 3A on new bone formation in a rat calvarial defect model.

PURPOSE: This study investigates the effects of semaphorin 3A on new bone formation in an experimental rat model. MATERIALS AND METHODS: Cortical bone defects, 5 mm, were created in the calvaria of 40 Wistar rats, which were then separated into three groups: empty defect (control) group, collagen group, collagen + semaphorin 3A group. The bone blocks were harvested after 4 and 8 weeks. New bone formation was assessed by micro-computed tomography (micro-CT), histology, histomorphometry, transmission electron microscope (TEM) and immunohistochemistry. RESULTS: Increased bone formation was observed in collagen + semaphorin 3A groups both histologically and with micro-CT. In the histomorphometic analysis, the control group had significantly less bone formation compared to both the collagen and collagen + semaphorin 3A group at 4 weeks (p = 0.0001) and 8 weeks (p = 0.0001). The collagen group had significantly less bone formation compared to collagen + semaphorin 3A group both at 4 weeks (p = 0.002) and 8 weeks (p = 0.005). Immunohistochemical analysis revealed that semaphorin 3A inhibited receptor activator of nuclear factor-kB ligand (RANKL) expression and increased the expressions of osteoblastic bone markers at 4 weeks. In TEM analysis, the collagen + semaphorin 3A group had an increased proliferation and bone formation rate at 4 weeks, whereas bone quantity and maturation were enhanced at 8 weeks. CONCLUSION: Locally applied semaphorin 3A increases callus formation at 4 weeks and bone formation at 8 weeks. Semaphorin 3A prevents bone resorption by inhibiting osteoclasts and increases bone formation by inducing osteoblasts.

The effects of preadministration of local anesthetic on pulsed radiofrequency

Background/aim: Pulsed radiofrequency (PRF) has been reported to be a safe and reliable method for the management of a variety of chronic pain syndromes. It is not known whether the preadministration of local anesthetic increases the size of the electrical field. We revealed the effects of administering local anesthetic on PRF and investigated whether they were related to local anesthetic or fluid effects. Materials and methods: Group 1 (n = 18) received PRF to the suprascapular nerve with 1 mL of bupivacaine, group 2 (n = 20) received PRF with 1 mL of physiological saline solution, and group 3 (n = 18) received PRF only. Results: There were significant improvements in visual analog scale (VAS) scores at 30 min, 1 month, and 3 months after treatment in group 1 (P < 0.05) and at 1 month and 3 months in groups 2 and 3 (P < 0.05). There was a significant improvement in VAS scores in group 1 compared with groups 2 and 3 at 30 min after treatment. Conclusion: PRF applied to the nerve along with local anesthetic may increase pain relief, especially in the early posttreatment period. The favorable effects may depend on the pharmacodynamic features of the local anesthetic .

Michigan Hand Outcomes Questionnaire in rheumatoid arthritis patients: relationship with disease activity, quality of life, and handgrip strength.

BACKGROUND AND OBJECTIVES: The aim of this study was to investigate the clinical relevance of Michigan Hand Outcomes Questionnaire (MHQ) in patients with rheumatoid arthritis (RA) and to evaluate the relationship between MHQ and disease activity, quality of life (QL), and handgrip strength separately. MATERIAL AND METHOD: Eighty RA were included in the study. Disease activity is evaluated with Disease Activity Score 28 (DAS28), pain is evaluated with Visual Analog Scale (VAS). The Disabilities of Arm, Shoulder and Hand (DASH), MHQ, Short-Form 36 (SF-36), and Health Assessment Questionnaire (HAQ), Arthritis Impact Measurement Scales-hand and finger function scale-2 (AIMS-2) were completed by all patients. Hand muscle strength (HMS) was measured with a hand-held dynamometer. RESULTS: The MHQ moderately correlated with DAS28. When the patients were grouped according to three disease activity measurements, DASH scores were significantly higher with higher disease activity and MHQ scores were significantly lower with higher disease activity. A high correlation was found between MHQ total and HAQ, AIMS-2. The SF-36 scores were correlated with MHQ scores. CONCLUSIONS: The MHQ scores correlate with disease activity indices, functional disability, QL and DASH. The clinical relevance of MHQ, like DASH, is high and both questionnaires can be used effectively.
