Risks of carpal tunnel syndrome and carpal tunnel release surgery in users of sodium-glucose cotransporter 2 inhibitors and glucagon-like peptide-1 receptor agonists: a target trial emulation study

AimPreclinical studies have shown that sodium-glucose cotransporter 2 inhibitors (SGLT2is) have a neuroprotective effect. This study compared the risks of carpal tunnel syndrome and carpal tunnel release surgery between new users of SGLT2is and new users of glucagon-like peptide-1 receptor agonists (GLP-1RAs). MethodsA retrospective new-user active comparator cohort study with a target trial design was conducted by using the TriNetX platform. Patients with type 2 diabetes mellitus prescribed SGLT2is or GLP-1RAs were identified. Covariates were balanced using propensity score matching to form 2 homogenous treatment groups. Outcomes were the risk of carpal tunnel syndrome and the risk of carpal tunnel release surgery. Hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated using the TriNetX platform. ResultsThe crude cohort included 86188 and 100244 patients in the SGLT2is group and GLP-1RAs group, respectively. After matching, each group included 65464 patients. The SGLT2is group had an average age of 59.6 years, and 46% were women. The GLP-1RAs group had an average age of 59.5 years, and 45.9% were women. The incidences of carpal tunnel syndrome (HR: 0.928; 95% CI: 0.869 to 0.991) and carpal tunnel release surgery (HR: 0.840; 95% CI: 0.726 to 0.971) were significantly lower in the SGLT2is group than in the GLP-1RAs group. ConclusionIn patients with type 2 diabetes mellitus, SGLT2is seem to decrease the risk of carpal tunnel syndrome and the need for carpal tunnel release surgery. Prospective studies are required to confirm our results.

Association of carpal tunnel syndrome risk factors with treatment modality selection focusing on corticosteroid injection and surgery: A nationwide population-based study.

Several studies have revealed the risk factors for carpal tunnel syndrome (CTS). However, no studies have evaluated the influence of these risk factors on the selection of treatment modalities for CTS. This study aimed to determine the influence of CTS risk factors on the selection of CTS treatment modalities with a focus on corticosteroid injection (CI) and surgery. We conducted a retrospective cohort study of patients aged ≥20 years with newly diagnosed CTS in the Korean health insurance review and assessment service between 2010 and 2019. We evaluated the demographic information, the existence of CTS risk factors, and the applied treatment modalities for CTS, including CI and operation. The CTS risk factors include age, sex, diabetes mellitus, osteoarthritis of the hand or wrist, rheumatoid arthritis, hypothyroidism, gout, chronic kidney disease (CKD) on dialysis, antiestrogen or aromatase inhibitor medication, and a history of distal radius fracture (DRF). Multivariable logistic regression analyses were conducted. Age over 80 years was the most significantly associated factor for the selection of CI in CTS (odd ratio [OR], 2.149; 95% confidence interval [CI], 2.092 to 2.209; P < .001). Among underlying diseases or medications, CKD on dialysis (OR, 4.001; 95% CI, 3.819-4.193; P < .001) was the most significant associated factor for the selection of operation for CTS, followed by a history of DRF (OR, 1.803; 95% CI, 1.749-1.860; P < .001). Old age was the most significantly related factor for selecting CI. Among underlying diseases or medications, CKD on dialysis and the history of DRF were the most significantly related factors for selecting operative treatment. For these patients, clinicians should proactively consider an operation to reduce the long-term discomfort and economic burdens.

Variant to gene mapping for carpal tunnel syndrome risk loci implicates skeletal muscle regulatory elements

Carpal tunnel syndrome (CTS) is a common disorder caused by compression of the median nerve in the wrist, resulting in pain and numbness throughout the hand and forearm. While multiple behavioural and physiological factors influence CTS risk, a growing body of evidence supports a strong genetic contribution. Recent genome-wide association study (GWAS) efforts have reported 53 independent signals associated with CTS. While GWAS can identify genetic loci conferring risk, it does not determine which cell types drive the genetic aetiology of the trait, which variants are "causal" at a given signal, and which effector genes correspond to these non-coding variants. These obstacles limit interpretation of potential disease mechanisms. We analysed CTS GWAS findings in the context of chromatin conformation between gene promoters and accessible chromatin regions across cellular models of bone, skeletal muscle, adipocytes and neurons. We identified proxy variants in high LD with the lead CTS sentinel SNPs residing in promoter connected open chromatin in the skeletal muscle and bone contexts. We detected significant enrichment for heritability in skeletal muscle myotubes, as well as a weaker correlation in human mesenchymal stem cell-derived osteoblasts. In myotubes, our approach implicated 117 genes contacting 60 proxy variants corresponding to 20 of the 53 GWAS signals. In the osteoblast context we implicated 30 genes contacting 24 proxy variants coinciding with 12 signals, of which 19 genes shared. We subsequently prioritized BZW2 as a candidate effector gene in CTS and implicated it as novel gene that perturbs myocyte differentiation invitro. Taken together our results suggest that the CTS genetic component influences the size, integrity, and organization of multiple tissues surrounding the carpal tunnel, in particular muscle and bone, to predispose the nerve to being compressed in this disease setting.

Prevalence of Carpal Tunnel Syndrome During Pregnancy

Background: Carpal Tunnel Syndrome (CTS) is a common condition during pregnancy, associated with symptoms like tingling, numbness, and pain in the hand and arm due to median nerve compression. The prevalence and severity of CTS can increase due to physiological changes during pregnancy, such as fluid retention and hormonal fluctuations. Objective: This study aimed to determine the prevalence of CTS in pregnant women, identify the trimester with the highest occurrence, and assess the effectiveness of Phalen's and Durkan compression tests in diagnosing CTS during pregnancy. Methods: A cross-sectional study was conducted over six months at Akhtar Saeed Trust Teaching Hospital and Farooq Hospital, Lahore, involving 121 pregnant women. Participants were selected using non-probability convenience sampling and were divided by trimester. The diagnosis of CTS was confirmed through Phalen's and Durkan compression tests. Data analysis was performed using SPSS version 25, with a chi-square test to evaluate the association between CTS prevalence and pregnancy trimester. Results: The prevalence of CTS among the participants was identified as 33.1% with Phalen's test and 55.4% with Durkan's compression test. The third trimester showed the highest occurrence of CTS symptoms, with a significant increase in prevalence (p=0.005 for Phalen’s test and p=0.394 for Durkan compression test). The frequency of CTS symptoms was 28.9% in the first trimester, 32.2% in the second trimester, and 38.8% in the third trimester. Conclusion: The study confirms that CTS is prevalent among pregnant women, particularly in the third trimester. The findings emphasize the need for healthcare providers to be aware of the increased risk of CTS during pregnancy and the importance of early diagnosis and management to alleviate symptoms.

Association between the digit ratio (2D:4D), handgrip strength, wrist ratio, and body fat distribution in women with different carpal tunnel syndrome severity

BackgroundTo evaluate the relationship of the second to fourth digit ratio (2D:4D), a biomarker of prenatal sex hormone exposure, with wrist ratio (WR), wrist-palm ratio (WPR), body mass index (BMI), waist-hip ratio (WHR), and handgrip strength (HGS) in different carpal tunnel syndrome (CTS) severity. MethodThis study involved 90 female participants (aged 18 to 83) with CTS. According to CTS severity, the participants were divided into four groups: normal, mild, moderate, and severe. All parameters of hand anthropometry and body fat distribution were measured, and the mean 2D:4D, WR, WPR, HGS, BMI, and WHR values were compared based on CTS severity. Data were collected with a visual analog scale (VAS) for pain and a Likert (LS) scale for numbness severity. ResultsThe mean age, 2D:4D, WD, WW, WR, WPR, BMI, and HGS values showed a significant differences between CTS severity groups. We found that lower 2D:4D and higher WPR and BMI were associated with increased risk of CTS (AUC = 0.728) after removing the effect of age. Bilateral hands were affected in 38.9 % (70/180) of participants. Regression analysis showed that lower HGS can be used as independent variable for predicting the females having bilateral affected hands. The LS score was considerably higher in the severe and moderate groups. Also, the VAS score was significantly higher in the severe group. ConclusionThe findings of the study demonstrated an association between 2D:4D, WPR, and BMI among women, emphasizing the effect of intrauterine sex hormone exposure on late life CTS severity.

Is Carpal Tunnel Release Necessary in High-Energy Distal Fractures of the Radius?

Purpose This study aimed to compare the clinical outcomes of patients who underwent volar plate osteosynthesis for high-energy distal radius fracture (DRFx) and carpal tunnel release (CTR) for acute or subacute carpal tunnel syndrome (CTS) with patients who did not undergo CTR. Methods This study is a retrospective evaluation of all high-energy DRFx treated with volar plate osteosynthesis in a regional hospital between January 2021 and January 2023. All adult patients (≥18 years) who underwent open reduction and internal fixation were included in the study after obtaining approval from the internal review board of our institution. Only patients who underwent plate osteosynthesis of the volar aspect through a modified Henry incision and patients who underwent CTR through a classic separate incision were included in the study. Clinical results includehand dynamometry, visual analog scale (VAS) scores, and physical examination findings of patients who underwent volar plate osteosynthesis because of high-energy DRFx and CTR due to CTS in the acute and subacute periods were retrospectively examined. Results Among the patients who underwent volar plate osteosynthesis because of high-energy DRFx, no statistically significant difference was detected between the hand grip strength and VAS scores of patients who underwent CTR because of acute CTS and subacute CTS at the sixth postoperative week (p>0.05). Conclusion Prophylactic CTR may be performed in the same session in selected cases, such as DRFx caused by a high-energy injury, to establish a scale for DRFx at a high risk of CTS and avoid delays in treatment. CTR for transient CTS detected in the subacute period during outpatient follow-up does not improve clinical outcomes.

Carpal tunnel syndrome among Manitoba workers: Results from the Manitoba Occupational Disease Surveillance System.

Carpal tunnel syndrome (CTS) is associated with occupational high-force repetitive tasks and vibration. This project examines the relationship between CTS and work to: (1) identify jobs and industries with increased CTS risk; (2) explore whether there is a sex difference in the risk of CTS after controlling for occupation; and (3) determine whether any observed relationships persist after excluding Workers Compensation Board (WCB) accepted time-loss CTS claims. We linked 95.5% of time-loss WCB claims from 2006 to 2019 to provincial administrative health data. The cohort included 143,001 unique person-occupation combinations. CTS cases were defined as at least two medical claims for (ICD-9 354) within a 12-month period or a surgical claim for CTS from 2 years before the WCB claim to 3 years after. WCB accepted CTS time-loss claims not identified by the medical claims were also included. A total of 4302 individuals (3.0%) met the CTS definition. Analysis revealed that the hazard ratios (HRs) of CTS vary considerably with occupation. Sex-based differences in CTS risks were observed, both in low- and high-risk occupations. In many occupations with increased HR, the HR remained elevated after excluding accepted time-loss WCB cases. The risk of developing CTS varied with occupation. Job titles with ergonomic risk factors had higher risks than those with lower exposures. This finding remained after eliminating time-loss compensated WCB cases, suggesting that all cases of CTS in high risk jobs are not identified in WCB statistics. Female workers in some job titles had excess CTS cases compared to male workers within the same job title.

External wrist ratio is not a proxy for internal carpal tunnel shape: Implications for evaluating carpal tunnel syndrome risk.

Carpal tunnel syndrome (CTS) is highly prevalent, resulting in decreased function and increased need for costly healthcare services. External wrist ratio (depth/width >0.70) is a strong predictor of the development of CTS and has been suggested to be a proxy for internal carpal tunnel (CT) shape. Conversely, sonography can more directly evaluate CT shape. The purpose of our study was to explore the relationship between wrist ratio and sonographic CT measurements to (1) evaluate the reliability of sonographic CT measurements and (2) explore how external wrist measures relate to anthropometric features of the CT. We used sonographic imaging on a sample of healthy participants (n = 226) to measure CT cross-sectional area, depth, width, and depth/width ratio. We conducted exploratory correlation and regression analyses to identify relationships of these measures with external wrist ratio. Reliability for dominant and nondominant sonographic CT measures ranged from good to excellent (0.79-0.95). Despite a moderate correlation between CT width and depth and their external wrist counterparts (0.33-0.41, p < 0.001), wrist ratio and CT ratio demonstrated weak to no correlation (dominant: r = 0.12, p = 0.053; nondominant: r = 0.20, p = 0.002) and the mean CT ratio was far lower than the mean wrist ratio (0.45 vs. 0.71 bilaterally). Supporting this, we observed several key differences in the relationship between external wrist measures compared to corresponding CT measures. Additionally, regression analyses combining participant factors and CT measurements produced models accounting for less than 15% of the variability in external wrist ratio (linear models) or correctly predicting less than 68% of wrist ratio-based risk categorization (logistic models). Overall, among healthy young adults, wrist shape is not an adequate proxy for CT shape.

The Carpal Tunnel Syndrome and Ergonomic Risk Factor Profile in Online Motorcycle Taxi Drivers (ojol) in Jakarta

Introduction: The increasing need for online motorcycle taxi driver (ojol) transportation continues to increase in Jakarta. This increases the activity of motorcycle taxi drivers, which can cause Carpal tunnel syndrome risks due to the awkward posture of the wrist while riding the motorcycle (the wrist posture is too long on the motorcycle handlebars with repetitive motion), which will affect the nerves and blood supply to the wrist and hand. This study aims to determine the risk of the motorcycle taxi driver’s upper limb using Rapid Upper Limb Assessment (RULA) and Carpal tunnel syndrome risk factor using the Boston Carpal Tunnel Syndrome Questionnaire (BTCSQ). Method: This research used a cross-sectional study approach with 97 respondents online motorcycle taxi drivers. The respondents were collected based on the activity of online motorcycle taxi drivers who were in or passing through the data collection location and willing to take part in the Rapid Upper Limb Assessment (RULA) and the Boston Carpal Tunnel Syndrome Questionnaire (BTCSQ). The RULA assessment and analysis were performed and supported by video (recording from a cycle of the activity while the respondents were riding the motorcycles). The respondents’ criteria were an online motorcycle taxi driver with a minimum of 1 year of working experience, at least 3 hours working duration per day, and not clinically suffering from rheumatoid arthritis and wrist problems. This study has been approved by Universitas Kristen Krida Wacana ethical committee. Result: The results of BCTSQ and RULA in online motorcycle taxi drivers have found that there’s mild–moderate risk respectively in Jakarta. In RULA, it was found that there were 87.6% of respondents were reported at moderate risk which had an impact on musculoskeletal problems, especially the upper limb. In the BCTSQ, the result showed that there were mild complaints in 38.1% of respondents regarding the wrist which was at risk of developing carpal tunnel syndrome. Discussion: With RULA results, in the form of moderate risk, Further ergonomics investigation and assessment are needed to find out further risk factors, mitigation plans, and best improvements to reduce the risks. The occurrence of mild complaints in the wrist based on BCTSQ requires further clinical examination of carpal tunnel syndrome to reduce the incidence of CTS cases in online motorcycle taxi drivers. Conclusion: This research’s result has found mild-moderate risk factors from the activity and working posture among online motorcycle taxi drivers in Jakarta. Further investigation and research ergonomically are needed.

Carpal Tunnel Syndrome as a Complication of Surgical Scaphoid Reconstruction in Nonunion and Secondary Fracture Dislocation

AbstractThe purpose of this study was to identify risk factors for postoperative carpal tunnel syndrome (CTS) in operative management for scaphoid nonunion and secondary fracture dislocation, treated surgically with takedown and bone grafting. We reviewed medical records of all our patients that underwent carpal tunnel release after scaphoid reconstruction surgery from August 2002 to December 2020. We identified a total of 7 out of 191 patients (3.7%). We investigated surgical parameters, pre- to postoperative changes, in three-dimensional measurements of the scaphoid and carpal tunnel morphometry. We found the preoperative intrascaphoid angle (ISA) and the postoperative change in ISA to correlate with an increased risk of postoperative CTS. Patients undergoing operative scaphoid reconstruction that require a high degree of geometric correction can be at risk to develop postoperative CTS, hence they should be subject to a lower threshold decision for prophylactic carpal tunnel release. Level of Evidence Level III.

A systematic review Risk Factors of Carpal Tunnel Syndrome in Food Industry Workers

Carpal Tunnel Syndrome (CTS) is a health disorder that occurs due to compression of the median nerve in the carpal tunnel with the main symptoms being tingling and pain in the fingers and hands which are innervated by the median nerve. CTS is a multifactorial disease, involving various risk factors (occupational, non-occupational). CTS is at risk of occurring in various industrial sectors, especially workers in the clothing industry, food and beverage industry, and agriculture who cause repetitive movements or maintain unergonomic work postures. CTS has become the center of attention of researchers because it can cause disability in workers, disrupting work productivity. This study aims to analyze the risk factors for CTS in food industry workers. This type of research is a systematic review that was searched via Google Scholars, PubMed, Cochrane Library, ResearchGate and Science Direct with a publication deadline of the last 5 years. The research results showed that 33 journals contained the topic of CTS risk factors in food industry workers. Based on 33 journals, it was found that the factors that cause Carpal Tunnel Syndrome are divided into occupational and non-occupational risk factors. Occupational risk factors include work duration, non-ergonomic workplace, work experience, repetitive wrist movements, hand position and body posture, and exposure to vibration. Apart from that, non-occupational factors include underlying disease, age, female gender, obesity, smoking. The conclusion of this research is that the risk factors for Carpal Tunnel Syndrome (CTS) in food industry workers are caused by various things. In general, it consists of occupational and non-occupational risk factors.

Prevalence of Carpel Tunnel Syndrome among Dentists, A Cross-Sectional Study

Background: Carpal Tunnel Syndrome (CTS) is a neuromuscular disorder predominantly seen in professions demanding repetitive and forceful hand movements, notably among dentists. This study aimed to assess the prevalence of CTS among dentists and its impact on their professional activities. Objective: To determine the prevalence of CTS in dentists and understand how it affects their daily professional tasks. Methods: This cross-sectional study utilized the Boston Carpal Tunnel Questionnaire to evaluate sensory and functional impairments in a sample of 50 dentists. The questionnaire encompassed demographic details, the Functional Status Scale (FSS), and the Symptom Severity Scale (SSS). Data analysis was conducted using SPSS version 28.0. Results: The study sample comprised 38% female and 62% male dentists, primarily aged between 20-30 years (48%), followed by 31-40 years (30%), and 41-50 years (22%). It was found that female dentists exhibited a higher prevalence of CTS compared to male counterparts. Regarding symptoms, 40% of the participants reported mild hand or wrist pain during the day, while 10% experienced moderate pain. Furthermore, 30% of the dentists reported experiencing wrist pain 1-2 times per day. A notable 40% felt slight weakness in the hands, and 6% reported moderate weakness. Conclusion: The study concludes that CTS is highly prevalent among dentists, with a more significant impact observed in female practitioners. These findings highlight the need for targeted preventive measures and ergonomic interventions in dental practice to reduce the risk and burden of CTS.

Carpal Tunnel Syndrome in Motorbike Riders: Prevalence, Severity, and Implications for Occupational Health

The clinical diagnosis of Carpal Tunnel Syndrome (CTS) is based on a collection of symptoms and indicators that point to compression of the median nerve within the carpal tunnel. Objective: To find out the severity, functional status, and pain of carpal tunnel syndrome in motorbike riders using BCTQ and NPRS. Methods: A cross-sectional study was conducted in 4 months on 169 motorbike riders in Faisalabad based on inclusion and exclusion criteria after obtaining consent. Phalen test was used to see carpal tunnel syndrome. Pain identification was done by using BCTQ in the selected subjects. Data were evaluated by SPSS version 22. Pearson Chi-Square test was applied for BCTQ symptom severity and functional limitation. Results: Data showed that all 169 participants were men. It also demonstrated that 42% fall in the category of 20-24 years, 33.1% fall in the 25-29 years category, and 24.9% fall in the age category of 30-34 years. The distribution showed that the prevalence of carpal tunnel syndrome by the Phalen test was 13% (22) among motorbike riders (169). Conclusions: Bike riding is an occupational hazard for CTS. To lower the risk of CTS in occupations involving motorbike riders, programs utilizing ergonomic and industrial hygiene improvement must be developed and implemented. The study showed that the prevalence of CTS among motorbike riders was 13% and the mean ± S.D was 1.869 ± .3375.

Occupational Risk Factors of Carpal Tunnel Syndrome on Workers: A Literature Review

The median nerve at the wrist becomes crushed in a condition known as carpal tunnel syndrome (CTS), which causes pain, numbness, and tingling in the worker's hand's palm. Risk elements for CTS include things like uncomfortable body posture at work, repetitive hand motions, and vibration exposure. Reviewing prior research on the connection between CTS and potential risk factors such worker hand posture, exposure to hand-arm vibrations, and repetitive hand movements is the goal of this study. The research approach involves searching for relevant articles using the terms carpal tunnel syndrome AND (occupational risk factors OR uncomfortable posture OR hand-arm vibrations OR repeated hand movements) in databases like ScienceDirect, PubMed, ResearchGate, and Scopus. The study indicates that Carpal Tunnel Syndrome is related to repetitive hand movements, hand-arm vibrations, and awkward hand posture during work. This research implies the importance of awareness about occupational safety. Additionally, the study suggests that job designs considering repetitive hand movements, vibrations, and incorrect posture can reduce the risk of Carpal Tunnel Syndrome. Therefore, it is hoped that organizations and workers can collaborate to create a safer, healthier, and more productive work environment.

Screening Plasma Proteins for the Putative Drug Targets for Carpal Tunnel Syndrome.

Carpal tunnel syndrome (CTS) is one of the most common work-related musculoskeletal disorders. The present study sought to identify putative causal proteins for CTS. We conducted a two-sample Mendelian randomization (MR) analysis to evaluate the causal association between 2859 plasma proteins (N = 35,559) and CTS (N = 1,239,680) based on the published GWAS summary statistics. Then we replicated the significant associations using an independent plasma proteome GWAS (N = 10,708). Sensitivity analyses were conducted to validate the robustness of MR results. Multivariate MR and mediation analyses were conducted to evaluate the mediation effects of body mass index (BMI), type 2 diabetes (T2D), and arm tissue composition on the association between putative causal proteins and CTS. Colocalization analysis was used to examine whether the identified proteins and CTS shared causal variant(s). Finally, we evaluated druggability of the identified proteins. Ten plasma proteins were identified as putative causal markers for CTS, including sCD14, PVR, LTOR3, CTSS, SIGIRR, IFNL3, ASPN, TM11D, ASIP, and ITIH1. Sensitivity analyses and reverse MR analysis validated the robustness of their causal effects. Arm tissue composition, BMI, and T2D may play a fully/partial mediating role in the causal relationships of ASIP, TM11D, IFNL3, PVR, and LTOR3 with CTS. The association of ASPN and sCD14with CTS were supported by colocalization analysis. Druggability assessment demonstrated that sCD14, CTSS, TM11D, and IFNL3 were potential drug therapeutic targets. The present study identified several potential plasma proteins that were causally associated with CTS risk, providing new insights into the pathogenesis of protein-mediated CTS and offering potential targets for new therapies.

Prevalence of Carpal Tunnel Syndrome Symptoms Among Young Dentists.

Objectives Although age is a risk factor, carpal tunnel syndrome (CTS) can also affect younger individuals, particularly those involved in activities or occupations that require repetitive hand movements, forceful gripping, or prolonged wrist flexion/extension. This case-control study aimed to examine the prevalence of CTS symptoms and frequent object dropping among a group of young dentists who are exposed to CTS risk factors. Additionally, other reported risk factors for CTS, such as sex, obesity, and square wrist sign, were also investigated. Methods A total of 74 dentists (48 women, mean age 28.5 years), who are working at Istanbul Faculty of Dentistry, the largest dental school in Istanbul, which is the biggest city in Turkey, were included in the study. Additionally, 61 age- and sex-matched controls (38 women, mean age 27.9 years) were also recruited. The Edinburgh Hand Preference Questionnaire, Boston Carpal Tunnel Syndrome Questionnaire (BCTQ), a questionnaire for object dropping and occupational hand usage, anthropometric measurements of the hands, clinical neurologic examination, and electromyography intended for the detection of CTS were performed. Results The dentists had a higher total weekly hand usage duration compared to the controls (66.3 vs 44.8 hours, p<0.001). BCTQ scores and the frequency of object dropping were also significantly higher in dentists compared to controls (respective p values: 0.011, 0.003). Positive correlations were found between BCTQ scores, hand usage durations, and object dropping (respective p values: 0.001, <0.001). BCTQ scores were higher in women than in men (p=0.027). Electrophysiologic evidence of CTS was found in one dentist. Conclusions Symptoms of CTS may manifest in individuals at a younger age than predicted, primarily influenced by their occupation and the duration of hand usage. Dentists, in particular, report a higher incidence of complaints related to object dropping, which can be attributed to their frequent use of specialized tools and engagement in delicate tasks, resulting in heightened awareness. However, it can also potentially serve as an indicator of CTS.

The Role of Vitamin D in Carpal Tunnel Syndrome Risk and Supplementation Outcomes: A Systematic Review.

Carpal tunnel syndrome (CTS) is a debilitating neuropathy that accompanies pain and other physical limitations and disrupts the normal functioning of the victims' lives. We aimed to investigate Vitamin D's preventive and therapeutic effects on the occurrence and remission of CTS symptoms. In this systematic review the PRISMA statement has been designed primarily. An extensive search was undertaken in various databases, including PubMed, Cochrane library, Web of Science, EMBASE, and Scopus. After considering the inclusion and exclusion criteria of the study, finally, 19 articles were retrieved. The raw data were extracted and entered into an Excel form, and the study outcomes were investigated. The main symptoms and tests, including functional score, nerve conduction, and pain, were improved after Vitamin D supplementation in CTS patients. However, they revealed worse scores in people with low Vitamin D levels. In addition, the scores of mentioned indices were worsened in people with lower serum Vitamin D levels. Nevertheless, some studies did not find a significant relationship between low serum 25(OH)D and more significant pain scores in CTS patients. In addition, Vitamin D inserts its effects on CTS by regulating cell proliferation, nerve growth factor, suppression of oxidative stress and inflammatory cytokines, and improvement in cartilage and microvascular damage. Vitamin D supplementation can improve the symptoms in CTS patients, and low serum 25(OH)D can aggravate the symptoms of the disease and could be a risk factor for its occurrence. However, more observational studies and clinical trials are needed.

Is the Duration Of Riding Vespas Related To The Risk Of Carpal Tunnel Syndrome?

Vespa is a popular scooter vehicle in Indonesia. The Vespa rider tends to use their wrist in flexion and extension positions while driving, especially when pulling vespa gas, controlling the brakes, and changing the gears. This repetitive movement could affect the suppression of the median nerve and cause the risk of carpal tunnel syndrome. The observational, analytic descriptive design was used to see the relationship between the duration of a Vespa ride and the risk of carpal tunnel syndrome in Vespa riders. 50 respondents were chosen using purposive sampling with inclusion and exclusion criteria in the Vespa Motorbike community of Malang City. A Carpal Tunnel Syndrome questionnaire was used to assess the risk of carpal tunnel syndrome. The Spearman Test was used to examine the relationship between both variables. All statistical analyses were performed using SPSS. The normality test showed the failure of the number of rearing data (p&lt;0,05). The Spearman test revealed that both groups had a significant relationship (p=0,002). We concluded that there is a relationship between the duration of riding and the risk of carpal tunnel syndrome in Vespa riders.&#x0D; Keywords: Duration of riding, Vespa riders, Carpal Tunnel Syndrome

Carpal tunnel syndrome in dentists compared to other populations: A nationwide population-based study in Taiwan.

Dentists may be at a higher risk of developing carpal tunnel syndrome (CTS) because of their use of frequent wrist and vibratory instruments at work; however, this issue remains unclear. Therefore, we conducted this study to clarify it. Taiwan National Health Insurance Research Database was used for this nationwide population-based study. We identified 11,084 dentists, 74,901 non-dentist healthcare professionals (HCPs), and identical number of age- and sex-matched participants from the general population. Participants who had the diagnosis of CTS before 2007 were excluded. Between 2007 and 2011, the risk of developing CTS among dentists, non-dentist HCPs, and the general population was compared by following their medical histories. The cumulative incidence rate of CTS among dentists was 0.5% during the 5-year follow-up period. In dentists, the risk was higher in women (women: 0.7%; men: 0.4%) and older individuals (≥60 years: 1.0%; <60 years: 0.4%). After adjusting for age, sex, and underlying comorbidities, dentists had a lower risk of CTS than the general population (adjusted odds ratio [AOR]: 0.65, 95% confidence interval [CI]: 0.45-0.92). Dentists had a higher risk for CTS compared with non-dentist HCPs, although the difference was not statistically significant (AOR: 1.21; 95% CI: 0.90-1.64). In CTS, dentists had a lower risk than the general population and a trend of higher risk than non-dentist HCPs. The difference between dentists and non-dentist HCPs suggests that we should pay attention to dentists for potential occupational risk of this disease. However, further studies are warranted to better clarify it.

An Integrated Review of Carpal Tunnel Syndrome: New Insights to an Old Problem.

Carpal tunnel syndrome (CTS) is a common entrapment neuropathy characterized by pain, numbness, and impaired function of the hand due to compression of the median nerve at the level of the wrist. Although CTS can develop from repetitive strain, injury, or medical conditions, there are also congenital and genetic risk factors that can predispose individuals to the condition. With respect to anatomical factors, some individuals are born with a smaller carpal tunnel, which increases their susceptibility to median nerve compression. Variations in specific genes, such as those encoding proteins involved in extracellular matrix remodeling, inflammation, and nerve function, have also been linked to an increased risk for CTS. CTS is associated with a high cost of health care maintenance and loss of work productivity. Therefore, it is vital that primary care physicians fully understand the anatomy, epidemiology, pathophysiology, etiology, and risk factors of CTS, so they can be proactive in prevention, diagnosing, and guiding proper treatment. This integrated review also provides insights into how biological, genetic, environmental, and occupational factors interact with structural elements to determine who is most likely to acquire and suffer from CTS. Keeping health practitioners abreast of all the factors that could impact CTS should go a long way in decreasing the health care and socioeconomic burden of CTS.
