Prevalence and Risk Factors Associated With Carpal Tunnel Syndrome Among Sudanese Females: A Cross-Sectional Study.

Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy resulting from compression of the median nerve. This condition is more common in females than in males. The earlier the diagnosis, the better the prognosis and treatment outcomes. This is a cross-sectional hospital-based study conducted at Soba Teaching Hospital in obstetrics and gynecology outpatient clinic in Khartoum in the period from February 2022 to March 2022. A simple random sampling was applied, and an interview was conducted using a four-partquestionnaire. The first part was based on socio-demographic data, the second was lifestyle, and the third and fourth were based on the Boston Carpal Tunnel Questionnaire (BCTQ). The data were analyzed using the statistical package for social sciences (SPSS) software, version 23 (IBM Corp., Armonk, NY) to find the correlation between the various variables. A total of 113 women participated in the study (response rate=100%). The prevalence of CTS was found to be 5%. No significant association was found between lifestyle and medical history, e.g., obesity and oral contraceptives and CTS were p=0.167, 0.841 respectively. Conversely, there was a significant association between age and residency, with p=0.005 and 0.049, respectively. The prevalence of CTS is increasing in Sudan. Therefore, it is essential to thoroughly assess patients for any symptoms related to hand pain by asking detailed questions during consultations. In addition, further studies covering more states are neededto better understand the regional variation in CTS prevalence.

Relationship Between Pain, Muscle Strength, Function, and Quality of Life in Overhead Players With Chronic Internal Shoulder Impingement

Background and Objectives: This study aims to determine the relationship between pain, muscle strength, function, and quality of life (QoL) in overhead players with chronic shoulder internal impingement syndrome. Methods: Forty-seven overhead players consisting of 15 men, 32 and women (mean age 32.45±7.2) with chronic shoulder internal impingement were enrolled. The pain was measured by a visual analogue scale (VAS). Disabilities of the arm, shoulder, and hand (DASH) and shoulder pain and disability index (SPADI) questionnaires were used to measure pain and function, and a short form (SF)-36 questionnaire to measure QoL. Muscle strengths were evaluated in both hands with a hand-held dynamometer and players were asked to hold the maximal voluntary isometric contraction (MVIC) in the middle range for 3 s and rest for 30 s between each test and each contraction was repeated three times on both affected and healthy side and the average of contractions was considered for each side. Results: The study showed a significant relationship between pain, the strength of shoulder muscle groups (-0.354), function (-0.935), and QoL (-0.861) in overhead throwers with chronic shoulder internal impingement syndrome and the strength of internal rotators of the affected shoulder decreased more than others. (P<0.05) Conclusions: This correlational study showed a significant relationship between pain and strength of shoulder muscles and function and QoL in overhead throwers with this syndrome.

Arthrodesis of the Distal Interphalangeal Joint of the Finger Using an Intramedullary Implant

Osteoarthritis (OA) of the joints of the hand is one of the most common musculoskeletal disorders in the elderly population. It is a complex, degenerative disease affecting all components of the joint. Surgical treatment is indicated when conservative therapy fails. The ultimate solution is arthrodesis of the distal interphalangeal (DIP) joint. Various methods of arthrodesis have been described, ranging from the use of K-wires or compression screw to different types of intra-articular (intramedullary) implants. The aim of this study is to evaluate the surgical outcomes of arthrodesis of the distal interphalangeal (DIP) joint of the fingers using intramedullary implants. Since 2011, arthrodesis of the distal interphalangeal joint using an intramedullary implant has been performed at our department 97 times in total, in 59 patients. 9 patients (15 cases of arthrodesis) were excluded from the study group due to their failure to complete the questionnaire, 1 female patient died. In the final group, 82 cases of arthrodesis in 49 patients (47 women, 2 men) were evaluated. In 72% of cases, the surgery was performed on the dominant hand. The mean age at the time of surgery was 58 years (median 59 years). The patients were indicated for surgery after the failure of all conservative treatment options. In addition to radiographs, also the hand function and pain were assessed based on the preand postoperative DASH score questionnaires. The surgical outcomes for all implants are satisfactory. In all 82 patients, the surgical wounds healed per primam. In one case, implant extraction was performed due to infection. Another complication was an unhealed fusion and formation of a non-union with minimum pathological mobility (the patient is satisfied with the outcome). In three patients, a fracture at the base of the distal phalanx was observed on postoperative radiographs, which fully healed within 3 months after surgery. The mean DASH score decreased from 41.95 preoperatively to 14.93 postoperatively. The mean time to healing of the arthrodesis observed on radiographs was 9.1 weeks. Currently, there are many different types of arthrodesis of the distal interphalangeal joint of the hand. Each method has its pros and cons. Arthrodesis using an intramedullary implant has the advantages of the older methods while minimizing postoperative complications. Our results are comparable to those reported in the foreign literature. Based on the evaluated outcomes, arthrodesis of the distal interphalangeal joint using an intramedullary implant can be considered valid. It definitely deserves to be included in the portfolio of surgical treatment of osteoarthritis of the DIP joints of the hand. According to our observation, the differences between various types of implants are minimal and their outcomes are comparable to those reported in foreign publications. The pain relief, restored finger function and fusion rate are comparable to, if not better than, those achieved by the older surgical methods. The advantage of this method is mainly easier implantation, fewer complications, and the possibility of implantation without the use of an X-ray image intensifier, which ultimately reduces the cost of surgery. The main disadvantage is the higher purchase price of the implant. osteoarthritis, distal interphalangeal joint, arthrodesis.

Case report: hypertrophic osteoarthropathy improves with immune checkpoint inhibitor therapy.

We report a case of a 66 year-old male with recurrent stage IIIA non-small cell lung cancer (NSCLC) and no prior arthritis or bone disease who developed hypertrophic osteoarthropathy (HOA) prior to immunotherapy treatment. Approximately one month after the first durvalumab infusion and without other interventions for symptom management, the patient reported improvements to his hand pain, with complete resolution of symptoms after five durvalumab treatments. Repeat x-ray after nine cycles of durvalumab showed decreased periosteal thickening of the phalanges bilaterally. He had no evidence of recurrent NSCLC based on serial computed tomography one year after durvalumab initiation. To our knowledge, there are no documented reports on the isolated effect of immune-checkpoint inhibitor (ICI) therapy on HOA. This case suggests that durvalumab may have a positive role in the management of HOA in NSCLC patients. Further research is needed to better understand the interaction of ICIs, HOA and other paraneoplastic syndromes.

Preliminary application of ulnar cortex transverse transport technique in treatment of upper extremity thromboangiitis obliterans

To investigate the feasibility and effectiveness of ulnar cortex transverse transport technique in treating upper extremity thromboangiitis obliterans (TAO). A retrospective analysis was conducted on the clinical data of 7 male patients with upper extremity TAO who were admitted and met the inclusion criteria between January 2019 and July 2022. The patients ranged in age from 32 to 50 years, with a mean age of 40.1 years. The disease duration ranged from 6 to 24 months, averaging 13.6 months. The smoking history ranged from 8 to 31 years, with a mean of 18.4 years. All patients presented with finger ulcers or gangrene, including 1 case affecting the thumb and index finger, 1 case affecting the index and middle fingers, 1 case affecting the middle and ring fingers, 1 case affecting only the ring finger, and 3 cases affecting the ring and little fingers. The preoperative visual analogue scale (VAS) score was 9.1±0.7. All patients underwent treatment with the ulnar cortext transverse transport technique. The wound healing time and the disappearance time of rest pain were recorded. The VAS score was used to assess the degree of hand pain before and after operation. Serum interleukin 6 (IL-6) levels were measured before operation and at 1 month after operation. Computed tomography angiography (CTA) of the affected limb was performed before operation and at 3 months after operation to evaluate changes in blood vessels. The clinical outcomes were evaluated at 1 year after operation based on the Patwa and Krishnan grading system. All 7 patients were followed up 12-17 months, with an average of 13.7 months. All patients experienced successful healing of ulcers, with wound healing time ranging from 14 to 21 days, averaging 17.3 days. During the follow-up, no complication occurred, and there was no recurrence of ulcers. The disappearance time of rest pain ranged from 8 to 15 days, averaging 12.1 days. The pre- and post-operative (1-month) serum IL-6 levels were (25.1±5.9) pg/mL and (11.9±2.9) pg/mL, respectively, with a significant difference ( t=5.363, P=0.002). CTA examination at 3 months after operation revealed partial revascularization of upper extremity arteries and establishment of collateral circulation, showing significant improvement compared to preoperative status. The VAS scores at 1, 7, 28 days, and 6 months postoperatively were 6.4±0.8, 3.7±0.8, 0.6±0.8, and 0.1±0.4, respectively, all of which significantly improved compared to preoperative scores ( P<0.05). Furthermore, the VAS scores gradually decreased over time, with significant differences observed between postoperative time points ( P<0.05). At 1 year after operation, the effectiveness of all 7 patients were evaluated as excellent based on the Patwa and Krishnan grading system. The ulnar cortex transverse transport technique can improve blood circulation in the upper limb of patients with TAO, reconstruct microcirculation, inhibit inflammation, promote ulcer healing, and alleviate limb pain.

De Quervain's tenosynovitis as an occupational disease in agricultural worker: A case report.

De Quervain's tenosynovitis is upper-limb disorder, more frequent in women. It is rarely recognized as an occupational disease. In this paper we reported work related de Quervain's tenosynovitis in cow milker. Ergonomic risk factors were assessed by utilizing assessment of repetitive tasks (ART) of the upper limbs method. Physical examination and imaging exams were used. We presented a 36-year-old female agricultural worker (workplace cow milker) exposed to work factors (forceful hand/wrist exertions, repetition, extreme postures) for 14 years. She was suffering the pain in the right hand, mainly near the thumb for few years. She was treated conservatively and surgically, however disability was permanent. Clinical examination showed slight edema of the right hand, increased palm's sweating. Patient had reduced range of movements and grip strength. Report shows that work-related factors were strongly associated with diagnosed de Quervain's tenosynovitis. Hand function plays an essential role in carrying out activities of daily living and this disorder pose a relevant burden of disease. Exposure to biomechanical factors should be an important initial target for the prevention of De Quervain's tenosynovitis in the working population.

The Gaming Disorder Identification Test (GADIT) - A screening tool for Gaming Disorder based on ICD-11.

Gaming Disorder was included as an addictive disorder in the latest version of the International Classification of Diseases (ICD-11), published in 2022. The present study aimed to develop a screening tool for Gaming Disorder, the Gaming Disorder Identification Test (GADIT), based on the four ICD-11 diagnostic criteria: impaired control, increasing priority, continued gaming despite harm, and functional impairment. We reviewed 297 questionnaire items from 48existing gaming addiction scales and selected 68 items based on content validity. Two datasets were collected: 1)an online panel (N = 803) from Australia, United States, United Kingdom andCanada, split into a development set (N = 589) and a validation dataset (N = 214); and 2) a university sample (N = 408) from Australia. Item response theory and confirmatory factor analyses were conducted to select eight items to form the GADIT. Validity was established by regressing theGADIT against known correlates of Gaming Disorder. Confirmatory factor analyses ofthe GADIT showed good model fit (RMSEA=<0.001-0.108; CFI = 0.98-1.00), and internal consistency was excellent (Cronbach's alphas = 0.77-0.92). GADIT scores were strongly associated with the Internet Gaming Disorder Test (IGDT-10), and significantly associated with gaming intensity, eye fatigue, hand pain, wrist pain, back or neck pain, and excessive in-game purchases, inboth the validation and the university sample datasets. The GADIT has strong psychometric properties in two independent samples from four English-speaking countries collected through different channels, and shown validity against existing scales and variables that are associated with Gaming Disorder. A cut-off of 5 is tentatively recommended for screening for Gaming Disorder.

A Rare Case of Carpal Tunnel Syndrome with Bifid Median Nerve and Palmaris Profundus Muscle

Summary: Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy. We report an extremely rare case of CTS associated with a bifid median nerve and palmaris profundus muscle. A 68-year-old man presented with numbness and pain in the right hand. Intraoperatively, a bifid median nerve was identified, with the ulnar branch severely compressed by the palmaris profundus muscle. The muscle was resected, leading to symptom resolution. Anatomical variations of the median nerve and anomalous muscles should be considered in CTS. Preoperative imaging and open carpal tunnel release are recommended to identify and address such variations.

Managing RS3PE: Diagnostic approach, initial steroid response, and long-term management with DMARDs

Background. RS3PE, or Remitting Seronegative Symmetrical Synovitis with Pitting Edema, is a unique and relatively rare form of inflammatory arthritis that predominantly affects older adults. It is distinguished by its hallmark features: symmetrical swelling of the joints, significant pitting edema in the extremities, and a negative serological profile for common markers associated with rheumatoid arthritis, such as rheumatoid factor (RA factor) and anti-citrullinated protein antibodies (anti-CCP). This condition is often characterized by a remitting course, meaning that symptoms may improve or resolve over time, particularly with appropriate treatment. The condition usually affects older adults and can sometimes be associated with other underlying health issues, such as malignancies or infections. The “remitting” aspect of RS3PE refers to the fact that the symptoms often improve or resolve over time, particularly with appropriate treatment, which usually involves corticosteroids or other anti-inflammatory medications. Case report. This case study details the clinical presentation, diagnosis, and management of a 56-year-old female patient with known hypertension who presented with bilateral dorsal hand swelling, pain, and early morning stiffness over a 15-day period. The patient’s initial examination revealed bilateral pitting edema and active arthritis in the proximal interphalangeal joints, with significant warmth and tenderness. Laboratory tests showed elevated ESR and CRP, normocytic normochromic anemia, and negative rheumatoid factor and anti-CCP antibodies. Imaging studies, including X-ray, ultrasound, and mammogram, showed no erosive changes or malignancy, while a Pap smear and serum CA-125 levels were within normal limits. The clinical picture, combined with the exclusion of other conditions, supported the diagnosis of RS3PE. Treatment commenced with intravenous low-dose dexamethasone, which led to significant symptomatic improvement. This was followed by a transition to oral prednisolone, and the patient initially showed complete resolution of symptoms. However, recurrence of symptoms occurred upon discharge, prompting the introduction of steroid-sparing agents: methotrexate and hydroxychloroquine, alongside continued oral steroid treatment. Over a two-month follow-up period, the patient experienced no signs of relapse. This case fits the clinical and investigative criteria for RS3PE. The patient showed symptomatic improvement after treatment with low-dose steroids.

Examining the relationship between smartphone characteristics and the prevalence of hand discomfort among university students

BackgroundStudents are among the groups that use smartphones for long periods throughout the day and night. Therefore, this study aimed to examine the relationship between smartphone characteristics and the prevalence of hand discomfort among university students.MethodsThis study included 204 university students, selected based on their willingness to participate and inclusion criteria. Participants reported hand pain and discomfort by completing the Cornell Hand Discomfort Questionnaire (CHDQ). Personal information was collected through a demographic questionnaire. Smartphone characteristics were obtained from the Internet based on the smartphone model self-reported by students.ResultsAccording to the Cornell questionnaire, 59.3% of students reported experiencing discomfort in their right hand, while 38.2% reported discomfort in their left hand due to smartphone use. Furthermore, 36.3% of students reported experiencing pain in two or more regions on their right hand, while 20.1% reported pain in two or more areas on their left hand. More than half of the students in the right hand (53.5%) and more than one-third (33.3%) in the left hand obtained pain scores of more than 1.5. The chi-square test indicated a statistically significant relationship between the weight of the smartphone and the prevalence of discomfort in the right hand (χ2 = 4.80, p = 0.03). Furthermore, a statistically significant relationship was found between the discomfort or pain scores experienced in both hands and the number of painful areas in those hands (right hand: χ2 = 219.04, p = 0.00; left hand: χ2 = 213.13, p = 0.00).ConclusionsSmartphone use can cause discomfort and pain in the hands of university students. The physical characteristics of the smartphone, such as its weight, play a significant role in contributing to right-hand-related pain among students. It is important to consider ergonomic factors in smartphone design and usage to reduce musculoskeletal problems among users, especially students.

Classical ayurveda management of TCH (taxane, carboplatin, and herceptin) based chemotherapy induced peripheral neuropathy- A case report

Although empirical data on the influence of Ayurveda on Chemo/Radiotherapy-induced side effects are limited, its methodological framework, grounded in a 'systems thinking' perspective, enables the precise delineation of the pathogenic stage of these side effects. This, in turn, facilitates the development of a strategy to address the decline in the quality of life parameters commonly associated with cancer treatment. Ayurveda personalized approach to disease management typically involves providing customized diets, lifestyle adjustments, medications, and detoxification therapies that target the entire body.We present a case involving a patient with numbness and pain in the right hand after undergoing chemotherapy who was referred to us by an oncologist for symptom management. This case report demonstrates the Ayurveda approach for establishing the etiology, pathogenesis, pathophysiology, and treatment of Chemotherapy-Induced Peripheral Neuropathy (CIPN) resulting from taxane-based chemotherapy. Following Ayurveda intervention, the patient exhibited significant improvements in symptoms and quality of life parameters.This case report systematically illustrates the application of Ayurveda approach in CIPN management.

Relapsing-Remitting Immunotherapy Responsive Small-Fiber Neuropathy: Longitudinal Tracking Through 10 Years Including Pregnancies.

To expand understanding of the pathogenesis, presentations, and treatment of initially idiopathic small fiber polyneuropathy (SFN). We longitudinally readministered validated metrics to track disease course and treatment responses in a previously healthy woman with acute, postinfectious, skin biopsy-confirmed, idiopathic SFN. During 5 years, viral respiratory infections triggered 3 separated episodes of acute, disabling burning hand, foot, and face pain (erythromelalgia). The initial 2 resolved with high-dose prednisone, and the third responded to repeated immunoglobulin treatments. Pregnancy with miscarriage triggered a fourth exacerbation refractory to corticosteroids and cyclosporin. Immunoglobulins restored total remission for 2 months; then, 2 rituximab doses slightly improved later flaring. Subsequently, daratumumab initiated 100-day remission later maintained by belimumab, initiated to permit another pregnancy. Remission continued after gestational week 13 all-treatment withdrawal. A week 30 fifth flare responded to plasmapheresis, with healthy birth at week 40. At 11-week postpartum, as symptoms returned, restarting belimumab restored remission maintained during ≥19 months of breastfeeding. This decade of tracking characterizes a relapsing-remitting course of SFN with initially separated monophasic episodes becoming more confluent, as with multiple sclerosis. This tempo and responsiveness to 5 immunotherapies suggest dysimmune causality. Validated metrics helped define the course and track treatment efficacy, particularly during pregnancy and breastfeeding. This is a single observational study without controls. This provides Class IV evidence.

The Impact of Work-Related Musculoskeletal Pains on Routine Tasks Among Operating Room Nurses: A Multicenter Cross-Sectional Study

PurposeTo determine work-related musculoskeletal pain (MSP) among 105 operating room nurses (ORNs) and its effect on their routine work. DesignMulticenter cross-sectional design. MethodsThis study was conducted with 105 nurses working in operating rooms of five different hospitals between December 15, 2021, and February 15, 2022. Data were collected using the “Nordic Musculoskeletal Questionnaire.” SPSS 22.0 was used for data analysis, and a significance level of p < .05 was established. ResultsAmong the nurses, 75.2% were female, 78.1% had undergraduate education, and 59% worked >40 hours/week. In the previous 12 months, 69.5% of ORNs experienced lower back pain; 68.6%, neck pain; and 61.9%, back pain. The duration spent working as a scrub nurse increased the possibility of experiencing pain in the hands, wrists, back, shoulders, and lower back region (p < .05), and women had an increased risk of lower back and back pain (p < .05). Neck, lower back, back, wrist, and hand pain increased the risk of being unable to perform daily tasks (p < .05). ConclusionsExtended work hours as a scrub nurse increase the risk of MSP, including lower back region, neck, and back pain among ORNs. Women have a higher risk of lower back and back pain. Addressing musculoskeletal issues in this profession is crucial. Clinical ImplicationsAddressing musculoskeletal discomfort is vital because of its impact on nurses’ job performance and potential patient harm. Providing ergonomic equipment, training nurses on musculoskeletal health, and raising awareness can help. It is also important to encourage regular breaks.

Ultrasound Guided Hydrodissection of Median Nerve with the Use of 5% Dextrose in Carpal Tunnel Syndrome: A Case Report

Carpal tunnel syndrome is an entrapment neuropathy of median nerve in wrist presenting with symptoms like pain, numbness, and paresthesia in hand and lateral three fingers. Conservative treatments are effective for mild to moderate cases, whereas severe or refractory carpal tunnel syndrome may require surgical intervention. Hydrodissection, a technique involving the separation of the nerve from surrounding tissues, has emerged as a minimally invasive and effective treatment option for carpal tunnel syndrome, leading to faster recovery and lower complication.In this case report, a 48 years female with two years history of severe pain and paresthesia in right hand, underwent ultrasound-guided hydrodissection of median nerve with 5% dextrose. Following intervention, the patient reported decreased symptoms and expressed satisfaction with the treatment during subsequent follow-up after 2 weeks. Ultrasound-guided hydrodissection of median nerve with 5% dextrose is effective treatment modality for patients with failed conservative management of carpal tunnel syndrome.

Unveiling workplace safety and health empowerment: Unraveling the key elements influencing occupational injuries

Introduction: Millions of workers globally experience work-related injuries, leading to fatalities, injuries, job loss, and wider societal implications. This study utilizes both the U.S. database and the General Social Survey (GSS) to delve into the factors linked to occupational injuries. Methods: In this study, 30 questions from the GSS between 2002 and 2014 were used. The sample included 5,914 workers from various sectors, distributed between both female and male, and were of 18 years and above. The analysis encompasses several dimensions: demographics, job-related characteristics, administrative factors, and health and safety measures. The study particularly focuses on assessing the prevalence of three common work-related injuries: nonfatal injuries, back pain and arm pain. Logistic regression models were constructed to gauge the effects of identified factors. Results: Significant insights emerge from the analysis. Factors such as age, gender, race, working hours, overtime work, trust in management, coworker support, and workflow smoothness were identified as having notable impacts on work-related injuries. For each model, the study quantifies these impacts through odds ratio and relative effects. For example, in the nonfatal injuries model, the relative effects of age showed that workers aged 65 years or older experience a 2.56% decrease in the frequency of nonfatal injuries compared to younger workers. Furthermore, in the back pain model, the estimated odds of having back pain in males are 0.90 lower than that in females. Moreover, in the arm pain model, workers who have sufficient time to complete their tasks have estimated odds of experiencing arm pain that are 0.85 lower than those who don’t have adequate time, etc. Conclusions: Understanding the intricate interplay of various factors influencing workers’ safety and health is vital for addressing occupational injuries. By addressing these factors, there’s potential for reducing work-related injuries, enhancing work environment, and minimizing costs. Practical Applications: Organizations can use the study’s findings for reducing work related injuries. Flexible work arrangements, tailored training programs, and ergonomic improvements might highlight factors such as age, gender, and working hours. Enhancing communication, fostering a positive work culture, and prioritizing safety and health measures could reduce risks associated with trusting management and coworker support. Cost-benefit analysis and continuous monitoring ensure these interventions’ effectiveness, reduce back and hand pain incidents, minimize cost, and create safer workplaces, thereby boosting the overall well-being of workers and organizational success.

The natural history of marginal erosions in hands with and without osteoarthritis.

Among people with or without hand osteoarthritis, we aimed to identify characteristics of people (e.g., age and gender) with marginal erosions (MEs). We also examined changes in MEs during 48months. We described radiographic severity and progression among joints with MEs, changes in MEs, or central erosions (CEs). We studied participants from the Osteoarthritis Initiative with baseline and 48-month hand radiographs. A radiologist and rheumatologist evaluated the radiographs for disease severity (Kellgren-Lawrence grades) and erosions (central or marginal), respectively. We used descriptive statistics to characterize participants and calculated frequencies at the joint level. Of the 3558 participants, 89 had a ME at baseline. People with MEs were more often male, older, and ever (former and current) smokers than those without a ME. There was no difference in inflammatory biomarkers or the presence of hand pain between individuals with and without a baseline ME. Almost all hands had only one ME (80%), whereas only 50% of individuals with CEs had only one CE at baseline. Compared to CEs, MEs appeared more frequently in joints without osteoarthritis (54% vs. < 1%). Approximately 18% of joints with an ME progressed in Kellgren-Lawrence grade versus 4% without ME. Among the joints with an ME at baseline, 10% resolved by 48months. Less than 0.1% of joints developed a new ME. MEs appear to be distinct from CEs. MEs are predominantly present in males, isolated to one specific joint without osteoarthritis within a hand, and possibly predictive of radiographic progression. Key Points • Marginal erosions appear to be distinct from central erosions. • Most marginal erosions occur in joints without radiographic osteoarthritis. • Radiographic progression but not hand pain is more common in joints with a marginal erosion than without one.

Efficacy of vitamin C on chemotherapy-related anemia in pancreatic cancer: study protocol for a randomized controlled trial

BackgroundIn the treatment of advanced pancreatic cancer, chemotherapy plays a pivotal role. Despite its effectiveness, this regimen is often marred by side effects such as anemia, neuropathy, fatigue, nausea, and malnutrition, which significantly affect patients’ tolerance to the treatment. Some studies have shown that vitamin C could potentially augment chemotherapy’s tolerability, notably by boosting iron absorption, ameliorating anemia, and relieving pain and numbness in hands and feet. Nevertheless, the integration of vitamin C with chemotherapy to mitigate toxic side effects and enhance the quality of life for advanced pancreatic cancer patients has not been examined in any randomized controlled trials to date.MethodsA prospective, single-center, open-label, randomized controlled trial will be conducted at Fudan University Shanghai Cancer Center from September 2023 to September 2026. A total of at least 100 patients with advanced pancreatic adenocarcinoma exhibiting distant metastases will be recruited and randomly assigned to the chemotherapy group or the chemotherapy plus vitamin C group. The primary endpoint is the rate of anemia. Secondary endpoints include the rate of grade 3 neuropathy, change of numeric rating scale, quality of life, and overall survival.DiscussionThis study aims to assess the impact of low-dose vitamin C on enhancing the quality of life for patients with metastatic pancreatic cancer undergoing gemcitabine and nab-paclitaxel chemotherapy.Trial registrationThe trial was registered with the ClinicalTrials.gov (NCT06018883) on August 31, 2023.

Metacarpal Stress Fractures in Athletes: A Systematic Review.

Stress fractures in general are common injuries; however, there is limited literature on metacarpal stress fractures in athletes. Our objective is to contribute the first systematic review of metacarpal stress fractures in athletes, with a particular focus on epidemiology, presentation, and outcomes. A systematic review regarding metacarpal stress fractures in athletes was performed via PubMed, EMBASE, MedLine, Cochrane, and Web of Science. Inclusion criteria consisted of case reports and case series of metacarpal stress fractures in athletes. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. A total of 11 studies (29 cases) were included. The mean patient age was 17 years, with 12 men and 15 women. The most common sports were tennis and badminton. The most common presentation was pain in the dorsal aspect of the hand related to activity. All patients underwent successful nonoperative management, with mean return to play of 9 weeks. Metacarpal stress fractures can present with significant pain and impact performance in athletes who perform sports involving repetitive movements of the hand and wrist. Nonoperative treatment, consisting of abstinence from sport until the patient was pain free combined with gradual return to play, was successful for all patients. The addition of proper technique and training load can result in satisfactory return to play. For patients who present with hand pain related to exercise, particularly a young racquet sport player, metacarpal stress fractures are a "can't miss" diagnosis associated with significant functional impairment.

The impact of smartphone use duration and posture on the prevalence of hand pain among college students

BackgroundExcessive smartphone usage among students can lead to discomfort in their hands and fingers. This study investigates the impact of smartphone holding posture, duration of usage, and the prevalence of wrist and finger pain among university students.MethodsThis cross-sectional study involved 213 university students who were selected based on inclusion criteria. Data was collected through a demographic information questionnaire. Participants self-reported five different postures for holding and interacting with a smartphone. The prevalence, frequency, severity, and interference of wrist and finger discomfort were assessed using the Cornell Hand Discomfort Questionnaires (CHDQ).ResultsThe study revealed that the average age of participants was 21.3 ± 2.2 years. On average, they had been using smartphones for 7.9 ± 3.1 years and spent an average of 4.9 ± 2.5 h daily holding them in their hands. In terms of discomfort, more than 25% of students reported pain in areas C (thumb finger), E (Palm Pollicis), and F (wrist) of the right hand, which was significantly related to the duration of holding the smartphone in that hand. Additionally, smartphone holding duration significantly affected areas D (palm) and F of the left hand, with over 11% of students experiencing discomfort. The most prevalent posture among students (41% of participants) involved holding the smartphone with the right hand only, with the thumb touching the screen. Notably, areas B (χ2 = 21.7), C (χ2 = 10.27), D (χ2 = 65.54), and E (χ2 = 59.49) of the right hand, as well as areas C (χ2 = 6.58) and E (χ2 = 44.28) of the left hand, exhibited significant associations with the postures of holding the smartphone.ConclusionsThe duration of smartphone use and the postures in which it is held contribute to the prevalence of discomfort in the thumb area and related muscles among right-handed students.

Recalcitrant Ulnar Sided Hand Pain in a Collegiate Golfer: A Case Report.

This case report details a diagnosis of myositis ossificans (MO) in a collegiate golfer with right ulnar-sided hand pain after striking the ground on a swing. Despite conservative treatment and a thorough workup, the patient's ulnar-sided hand pain did not improve. An ultrasound eventually revealed MO within the abductor digiti minimi muscle. The patient received an ultrasound-guided fenestration and injection of lidocaine and dexamethasone into the affected muscle, leading to complete symptom resolution. MO is often secondary to trauma, causing bone formation in soft tissue, leading to pain, limited range of motion (ROM), and disability. This case highlights the importance of considering MO in cases of persistent muscular pain and the diagnostic challenges related to ulnar-sided hand anatomy.
