Fragility spinal fractures among cirrhotic liver transplant candidates in Croatia.

INTRODUCTION: Existing data on fragility spinal fractures prevalence in liver transplant candidates are scarce and inconsistent. This may be due to other comorbidities, besides hepatic osteodystrophy (HO), that contribute to bone loss and fragility fracture prevalence in chronic liver disease (CLD). OBJECTIVES: The aim of this study was to investigate the prevalence of spinal thoracic and lumbar fragility fractures among cirrhotic, non-chronic kidney disease (CKD), non-diabetic liver transplant candidates and to explore their relationship with clinical characteristics, laboratory markers and dual-energy x-ray absorptiometry (DXA) results. MATERIAL AND METHODS: This cross-sectional observational study was conducted at Merkur University Hospital, Croatia, between February 2019 and May 2023. Adult patients with liver cirrhosis referred for liver transplantation were included. Patients with acute infection, CKD, diabetes mellitus, malignancies, inflammatory bone diseases and those on corticosteroid or antiresorptive therapy were excluded. Clinical, laboratory and radiological assessment was carried out and patients were accordingly allocated into non-fractured and fractured group for the purpose of statistical analysis. RESULTS: A total of 90 patients were included in the study. There was 123 fractures, 87 (70.7 %) in the thoracic and 36 (29.3 %) in the lumbar region. Eighty-nine (72.4 %) fractures were grade 1, 31 (25.2 %) were grade 2 and 3 (2.4 %) were grade 3. Patients in the fractured group were significantly older (p < 0.001). No significant differences between fractured and non-fractured group according to laboratory and DXA parameters were noted. Subgroup with lumbar fractures had significantly lower bone mineral density values at L1-L4 region. Statistically significant negative correlation between bone specific alkaline phosphatase (BALP) and hip total BMD (rho = -0.414, p < 0.001) and spine total BMD (rho = -0.258, p = 0.014) values was found. CONCLUSION: Present study confirmed detrimental impact of CLD and HO on bone strength. DXA measurement correlated with the presence of lumbar fragility fractures. A combination of standard X-ray imaging and DXA is needed for adequate bone evaluation in pretransplant period and BALP could be useful for detecting HO in CLD. Searching for other risk factors and implementing bone turnover markers and additional imaging techniques for bone loss evaluation in liver transplant candidates is needed.

Fibroblast growth factor 23 and its role in bone diseases.

Fibroblast growth factor 23 (FGF23) has been casually linked to numerous hypophosphatemic bone diseases, however connection with bone loss or fragility fractures is still a matter of debate. The purpose of this review is to explore and summarise the known actions of FGF23 in various pathological bone conditions. Besides implication in bone mineralisation, elevated FGF23 showed a pathological effecton bone remodelling, primarily by inhibiting osteoblast function. Unlike the weak association with bone mineral density, high values of FGF23 have been connected with fragility fracture prevalence. This review shows that its effects on bone are concomitantly present on multiple levels, affecting both qualitative and quantitative part of bone strength, eventually leading to impaired bone strength and increased tendency of fractures. Recognising FGF23 as a risk factor for the development of bone diseases and correcting its levels could lead to the reduction of morbidity and mortality in specific groups of patients.

Efficacy of therapeutic ultrasound in the treatment of chronic calcific shoulder tendinitis: a randomized trial.

BACKGROUND: Calcific shoulder tendinitis (CST) is characterized by hydroxyapatite crystals deposition in the rotator cuff tendons. Therapeutic exercises have been the mainstay of CST treatment, and evidence for therapeutic ultrasound (T-US) utilization and efficacy is lacking. AIM: This study aimed to determine whether 4500 J T-US combined with therapeutic exercises is superior to therapeutic exercises alone regarding calcification size reduction and symptom improvement in chronic symptomatic CST. DESIGN: This is a double-blind, placebo-controlled study. SETTING: This study was conducted at a University Department for Rheumatic Diseases and Rehabilitation of a University Hospital. POPULATION: Patients with chronic CST were analyzed. METHODS: After eligibility allocation, 46 patients with sonographically confirmed CST were divided into two groups (56 shoulders, 26 per group). Both groups performed the same therapeutic exercises for half an hour under physiotherapist supervision. In the treatment group T-US (4500 J, 10 minutes per session at a frequency of 1 MHz and an intensity of 1.5 W/cm2), and in the placebo group, sham T-US was applied for 4 weeks. Patients were assessed for: calcification size, shoulder pain, global health (GH), shoulder mobility (ROM), handgrip strength, Health Assessment Questionnaire Disability Index (HAQ-DI), Shoulder Pain and Disability Index (SPADI), and overall rehabilitation satisfaction. RESULTS: All assessed variables improved in both groups. A significantly greater reduction in calcification size was recorded in the treatment group compared to placebo: -10.92% (IQR 4.61% to 19.38%) versus -5.04% (2.30% to 7.22%), P=0.008. There was a significantly greater decrease in HAQ-DI, reduction of VAS GH, and an increase in hand grip strength in the treatment group, while no significant differences were observed for other parameters between the groups. CONCLUSIONS: Our results showed that adding the 4500 J T-US to therapeutic exercises in chronic symptomatic CST therapy resulted in greater calcification size reduction immediately following the treatment, as well as hand grip strength, HAQ-DI, and VAS GH improvement. CLINICAL REHABILITATION IMPACT: 4500 J T-US combined with therapeutic exercises is more effective in reducing calcification size than therapeutic exercises alone in the treatment of chronic symptomatic CST.

Local Cryotherapy, Comparison of Cold Air and Ice Massage on Pain and Handgrip Strength in Patients with Rheumatoid Arthritis.

BACKGROUND: The main benefits of cryotherapy in rheumatoid arthritis (RA) are in reducing inflammation and swelling and in relieving joint pain. This study aimed to compare the short-term effects of cold air therapy vs. ice massage, on pain and handgrip strength (HGS) in patients with RA. SUBJECTS AND METHODS: The study is a non-randomized clinical trial. Patients were recruited if they had disease activity score (DAS28) ≥3.2 with at least 2 swollen joints on the dominant hand and were consecutively divided into two groups of 15 patients. There was no statistically significant difference in DAS28 score between groups. The first group received cold air therapy at -30°C and the second ice massage of the hands. The pain (visual analogue scale, 0-10), and HGS (kg) were measured immediately prior and after cryotherapy, and 30 and 60 minutes after cryotherapy. Descriptive statistics, Independent Samples T-test, and Paired Samples T-test were used for statistical analysis. RESULTS: Pain intensities for cold air therapy were as follows: 5.33 (±2.44), 3.13 (±2.67), 2.87 (±2.56), 2.80 (±2.73), and for ice massage were: 5.20 (±2.37), 2.87 (±2.42), 2.60 (±2.23), 2.67 (±2.28). In both groups pain was significantly lower immediately after, 30 and 60 minutes after the treatment compared to the baseline (p=0.001). There was no significant difference in pain alleviation between the groups regarding the used method of cryotherapy on all three measured time points. Nonsignificant improvement in HGS occurred after both methods of cryotherapy. There was no significant correlation between pain intensity and HGS. CONCLUSIONS: A single application of cold air therapy and ice massage equally provides immediate and significant pain alleviation in patients with active RA, which is maintained for one hour. There is scientific evidence that HGS is influenced greatly by the disease activity. A single application of cryotherapy could not reduce disease activity explaining recorded nonsignificant effect on HGS.

The Impact of Disease Activity on Quality of Life, Fatigue, Functional Status and Physical Activity in Patients with Ankylosing Spondylitis.

BACKGROUND: Inflammatory back pain and stiffness are the leading symptoms of ankylosing spondylitis (AS). AS progression leads to substantial functional impairment and can reduce quality of life (QoL). The aim of this study was to determine the impact of disease activity on QoL, fatigue, functional status and physical activity. SUBJECTS AND METHODS: One hundred and fifty AS patients were included in the study, their body mass index (BMI) was calculated and they completed questionnaires regarding disease activity (The Bath Ankylosing Spondylitis Disease Activity Index, BASDAI) functional status (The Bath Ankylosing Spondylitis Functional Index, BASFI) spinal mobility (The Bath Ankylosing Spondylitis Metrology Index, BASMI), physical activity (the International Physical Activity Questionnaire, IPAQ), functional disability (The Health Assessment Questionnaire Disability Index, HAQ-DI), fatigue (The Functional Assessment of Chronic Illness Therapy - fatigue, FACIT-F) and QoL (The Short Form Survey-36, SF-36). RESULTS: Patients with inactive disease (BASDAI<4) had significantly better HAQ scores (p=0.001), SF-36 mental component scores - MCS (65.68±19.54 inactive vs. 46.89±21.78 active disease, p=0.001), SF-36 physical component scores - PCS (median score 56.25 inactive vs. 30.00 active disease, p=0.001) and FACIT-F scores (38.49±10.62 inactive vs. 26.21±10.81 active disease, p=0.001). There was no significant difference in patient's physical activity or BMI regarding disease activity (p=0.564 and p=0.162 respectively). Also, there was no significant difference in BASDAI, BASMI or BASFI scores regarding different BMI categories (p=0.818, p=0.474, p=0.436, respectively). CONCLUSION: AS activity increased fatigue, impaired functional ability and QoL, especially the physical component. Although more than half (61.4%) of our patients were categorized as pre-obese or obese according to BMI, this was not related to disease activity, spinal mobility or daily functioning scores. Reported physical activity level had no effect on disease activity. Disease activity influences the course of AS and QoL assessment should be implemented into regular AS evaluation in order to improve treatment outcome.

Influence of Non-pharmacological Treatment on Pain, Morning Stiffness, Fatigue, and Physical Function in Patients with Psoriatic Arthritis.

Naphthalanotherapy (NT) is a therapeutic procedure that uses mineral oil obtained from petroleum. The aim of this study was to investigate the influence of the duration of NT combined with an individually adjusted rehabilitation program (IARP) on pain, morning stiffness (MS), fatigue, and physical function in patients with psoriatic arthritis (PsA). A total of 29 consecutive patients with PsA were divided into two groups. Group 1 (n=17) participated in a two-week and Group 2 (n=12) in a three-week intervention program. Pain (using the Visual Analogue Scale - VAS), fatigue (VAS and Functional Assessment of Chronic Illness Therapy-Fatigue - FACIT-F), duration of MS (minutes), and physical function (Health Assessment Questionnaire - HAQ) were assessed before and after therapy. Statistical analysis was performed using SPSS version 20, with P<0.05. There was a significant improvement in VAS-pain, VAS-fatigue, MS, HAQ, and FACIT-F before vs after therapy: Group 1:5.88±1.62 vs 3.94±1.25, P=0.001; 6.59±1.73 vs 4.35±1.73, P=0.001; 35.47±31.64 vs 23.71±29.30, P=0.001; 1.43±0.78 vs 1.23±0.74, P=0.001; 25.88±10.89 vs 30.71±10.65, P=0.009; Group 2: 6.17±1.27 vs 3.92±1.44, P=0.001; 6.50±1.93 vs 3.75±1.71, P=0.001; 38.42±32.00 vs 21.25±17.31, P=0.006; 1.47±0.79 vs 0.93±0.54, P=0.008; 25.00±9.87 vs 36.83±7.20, P=0.001, respectively. Regarding the length of the therapy, significant difference was reached only in FACIT-F (P=0.009). Two-week and three-week NT combined with IARP are equally efficient in reduction of pain and MS, as well as in improving physical function in patients with PsA. The three-week program showed an additional effect on reducing fatigue assessed by the FACIT-F score.

Klippel-Feil syndrome misdiagnosed as spondyloarthropathy: case-based review.

Spondyloarthropathy refers to any joint disease of the vertebral column, but the term is mainly used for a specific group of disorders called seronegative spondyloarthropathies (SpAs). The axial skeletal involvement, peripheral and extra-articular manifestations and an association with the major histocompatibility complex class I human leukocyte antigen-B27 (HLA B27) are commonly shared features of SpAs. Klippel-Feil syndrome (KFS) is a rare congenital disorder characterized by the fusion of one or more cervical vertebrae, accompanied by various skeletal and extra-skeletal anomalies. We report a case of an adult male patient with HLA B27 positivity presenting with chronic cervical spine pain accompanied by morning stiffness and periodic night pain, with radiologically confirmed ankylosis and fusion of several cervical segments. His medical history included urogenital abnormalities operated in childhood and mild mitral prolapse. Initially suspected diagnosis of an early axial form of SpA was rejected after thorough workup. Instead, the nature of vertebral defects along with the past medical history of urogenital and cardiac abnormalities pointed towards the diagnosis of KFS. HLA B27 presence can be a confounder in patients presenting with spinal pain and that is why the differential diagnosis of CSD-s and SpA can be challenging in some patients.

Correspondence of vitamin D status with functional scores and disease activity among Croatian patients with ankylosing spondylitis: a preliminary study.

BACKGROUND: Ankylosing spondylitis (AS) is a chronic inflammatory rheumatic disease which primarily affects the axial spine and sacroiliac joints. Over the past several years Vitamin D has been recognized as a hormone with significant immunomodulatory effect due to the fact that it inhibits T-cell proliferation and decreases the production of interleukin-2, interferon-γ, and tumor necrosis factor-α. Therefore, vitamin D may play a role in the development and progression of inflammatory diseases. Our aim was to estimate and evaluate the correspondence of vitamin D status with functional scores, spinal mobility and disease activity among patients with AS in Croatia. SUBJECTS AND METHODS: One hundred and fifty (150) AS patients were prospectively enrolled and assessed for disease activity, spinal mobility and functional disability. Blood samples were obtained from all patients and 25(OH)D concentration and inflammatory markers were determined. All patients underwent bone mineral density measurement at the lumbar spine (L1-L4) and proximal femur (total hip and femoral neck) with dual-energy x-ray absorptiometry. RESULTS: The prevalence of 25(OH)D inadequacy considering cut-offs of 75, 50 and 30 nmol/L was 80, 46.7 and 16.7% respectively. The mean 25(OH)D serum concentration was 52.63±23.45 nmol/L. There was no significant difference in mean 25(OH)D concentration regarding patient's age, sex, smoking status, season change, disease activity, spinal mobility or functional scores. However, there was a trend towards lower 25(OH)D concentration in patients with higher disease activity, worse spinal mobility and worse functional scores. CONCLUSION: Our results showed that there is no significant association between serum 25(OH)D concentration and activity of AS. Given that significant proportion of our patients had inadequate vitamin D status, the role of vitamin D in pathophysiology of AS still remains to be elucidated.

Factors Contributing to the Reduction of Pain during Electromyography and Nerve Conduction Studies.

BACKGROUND: Electromyography (EMG) and nerve conduction studies (NCS) are an unpleasant and sometimes painful examinations. Pain can reduce patient's compliance and have a negative effect on the examination results. Different studies report that music affects pain perception by acting as a distractor, by inducing positive emotional valence or through the concept of convergence of different sensory modalities. The aim of this study was to explore the effect of music and different environmental and sociodemographic factors on pain perception during EMG and NCS. SUBJECTS AND METHODS: Sixty patients with suspected neuromuscular disease were randomized into music and control group. Specific questionnaire assessed sociodemographic characteristics, medical history, examination waiting time, examination extent and biometeorological forecast. The numerical rating scale was used for the evaluation of pain. The examiner evaluated patient's compliance after the examination. RESULTS: NCS was less painful for patients in the music group (p=0.03), as well as for more cooperative patients (p=0.011). For patients who previously underwent EMG/NCS, present NCS was more painful (p=0.001), regardless of the music intervention (p=0.019). EMG was more painful for older patients (p=0.041). Patients with lower level of education reported lower pain during NCS (p=0.026). Gender, financial satisfaction, biometeorological forecast, diabetes, depression or malignant disease, use and dosing of analgesics or antidepressants, symptoms, examination waiting time and the examination extent had no effect on pain perception. CONCLUSIONS: Music significantly decreased the perception of pain associated with NCS, but not the EMG portion of the examination. During EMG pain level was not significantly reduced, but the median of pain was still lower. Generally, the pain level during NCS, unlike the one during EMG, was affected by patients' compliance, level of education and painful predetermination. We propose using music during EMG/NCS because it can make the examination more comfortable for the patient and thus contribute to better quality of this examination.

Lateral Inverted Osteochondral Fracture of the Talus: Case Reports and Review of the Literature.

Lateral inverted osteochondral fracture of the talus (LIFT) is a rare variant of stage IV osteochondral lesion of the talus (OLT), where the fragment is inverted in situ by 180°. The management of LIFT lesion is very challenging and early recognition crucial, given that treatment options depend on the articular cartilage condition and sufficiency of the adjacent bone of the displaced fragment. We describe two LIFT cases referred from other institutions after unsuccessful conservative treatment of OLT. They presented with pain, swelling and tenderness over the anterolateral aspect of the right ankle. We recognized the LIFT lesion on the magnetic resonance imaging scans in patient 2, while in patient 1 the orientation of the fragment was recognized upon direct visualization during operative treatment. Both patients underwent arthroscopic procedure. Due to articular cartilage damage and insufficiency of the adjacent bone of the fragment, both patients were treated with excision fol-lowed by microfracture. Treatment of the LIFT lesion should start arthroscopically to allow clear evaluation of the osteochondral fragment, assessment of the talar defect and identification, as well as treatment of associated disorders. If the articular cartilage appears intact with sufficient subchondral bone, fixation of the fragment is optimal management, otherwise excision and microfracture can be the treatment of choice.

Prevalence and Correlation of Depressive Symptoms with Functional Scores, Therapy and Disease Activity among Croatian Patients with Rheumatoid Arthritis: A Preliminary Study.

BACKGROUND: Rheumatoid arthritis (RA) is a chronic, autoimmune and disabling disease that significantly affects the quality of life. Additionally, significant number of patients with RA suffer from depressive disorders, which are commonly underrecognised and undertreated. We aimed to estimate the prevalence of depressive symptoms in Croatian RA patients and to assess the relationship between them and clinical correlates. SUBJECTS AND METHODS: Fifty-four RA patients treated at the Clinic for Rheumatic Diseases and Rehabilitation at the University Hospital Centre Zagreb were prospectively enrolled in the study and evaluated for functional status using the Disease Activity Score 28 (DAS-28), Health Assessment Questionnaire (HAQ), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) and Visual Analogue Scale (VAS) for pain and health related quality of life (HRQL) measurement. The depressive symptoms were assessed using the Beck Depression Inventory-II (BDI-II) questionnaire. RESULTS: Thirty RA patients (55.6%) had some sort of mood disorder, with 10 (18.5%) patients accounting as depressed. Positive correlation was found between depressive symptoms, higher disease activity and disablity during daily activities (τb=0.385, p=0.001 and τb=0.282, p=0.024 respectively). We found no significant association between depression and disease activity in the whole sample of RA patients, but for postmenopausal patients, the disease activity correlated with postmenopausal patients accounting as depressed (BDI-II score moderate or severe; τb=0.363, p=0.021). The use of biologic therapy correlated negatively with the disease acitivity, pain intensity and worse health related quality of life score (τb=-0.360, p=0.06; τb=-0.310, p=0.07; τb=-0.380, p=0.01 respectively). CONCLUSION: Considering the high prevalence of depressive sympoms in RA patients and the effect on functional disability and quality of life, we wanted to emphasize the importance of recognizing and optimizing depression treatment through multidisciplinary approach in RA patients.
