The effect of lung-recruitment maneuver on postoperative shoulder pain in patients undergoing laparoscopic cholecystectomy: a randomized controlled trial.

PURPOSE: Lung-recruitment maneuvers (LRM) have been shown to reduce postoperative pain after laparoscopic surgery. This study aimed to investigate the association of LRM with the incidence of shoulder pain after laparoscopic cholecystectomy. METHODS: A randomized controlled study was conducted with 110 patients undergoing elective laparoscopic cholecystectomy from July 2022 to March 2023. Participants were randomized to receive either routine exsufflation or LRM at pneumoperitoneum release. The postoperative shoulder pain and abdominal pain were assessed at 1, 4, 6, 12, and 24 h after surgery using a numeric rating scale. Analgesic consumption and postoperative nausea or vomiting (PONV) were evaluated during the first 24 h after surgery. RESULTS: The incidence of shoulder pain during the first 24 h after surgery was significantly lower in the LRM group compared to the control group (26.9 vs. 59.3%; P = 0.001). The median [interquartile range] score of worst shoulder pain was significantly lower compared to the control group (3 [2-3] vs 4 [3-5.5]; P = 0.003). Participants in the LRM group showed reduced abdominal pain at rest at 4 and 24 h after surgery, and experienced significantly lower intensities of abdominal pain during mobilization at all time points over 24 h after surgery. There were no significant differences in opioid consumption or the incidence of PONV between the groups. CONCLUSIONS: LRM reduces both the incidence and intensity of shoulder pain during 24 h after laparoscopic cholecystectomy. Additionally, LRM was associated with reduced intensity of abdominal pain during mobilization over the study period.

An Unusual Case of Fever in Paralytic Ileus.

Still's disease is frequently a condition of exclusion for patients with an unidentified cause of fever. Accompanying symptoms typically include fever, arthralgia, and a transient skin rash. The underlying pathophysiology indicates an autoimmune origin. Diagnosis is primarily clinical, often utilizing the Yamaguchi criteria. The case in question involves a 19-year-old male presenting with high-grade fever and paralytic ileus. The patient received intravenous glucocorticoids and cyclophosphamide, resulting in a rapid clinical improvement. During the follow-up, tofacitinib was initiated based on the clinical response observed.

An exploration of clinical features and factors associated with pain frequency and pain intensity in children with growing pains: a cross-sectional study from Chongqing, China.

Instruction: Growing pains are the most common cause of musculoskeletal pain in children, affecting both children's and caregivers' well-being. The lack of definitive diagnostic criteria complicates diagnosis and treatment. Objectives: This study aims to outline the clinical features and identify factors associated with the frequency and intensity of growing pains in children in Chongqing, China. Methods: A cross-sectional study was conducted in a children's hospital using its Internet hospital follow-up platform. Children initially diagnosed with growing pains between July and September 2022 were enrolled. Sociodemographics, pain locations, duration, frequency, intensity, and potentially related factors were collected. Results: Eight hundred sixty-three children were enrolled (average age: 8.19 ± 3.24 years; 455 boys [52.72%]). Pain frequency was reported as quarterly (62.11%), monthly (24.80%), biweekly (1.74%), weekly (10.08%), and daily (1.27%). The prevalence of mild, moderate, and severe pain was 26.65%, 55.74%, and 17.61%, respectively. The knee was the most common pain location (63.85%), mostly encountered between 4 pm and 5 pm (20.51%). Multivariate analysis revealed that pain frequency negatively correlated with vitamin supplementation during pregnancy, positively correlated with underweight, bad temper, increased exercise, and cold lower extremities. Pain intensity positively correlated with irritability, increased exercise, and pain sensitivity but negatively correlated with age and vitamin supplementation during lactation. Conclusion: Growing pains typically occur on a quarterly basis, predominantly affecting the knees during 4 pm to 5 pm. Factors in sociodemographics, maternal aspect, temperament, and exercise levels can influence pain frequency and intensity. Clinicians should consider these aspects when developing comprehensive strategies for pain management.

Menstrual pain in Australian adolescent girls and its impact on regular activities: a population-based cohort analysis based on Longitudinal Study of Australian Children survey data.

OBJECTIVES: To determine the proportion of Australian adolescent girls who experience menstrual pain (dysmenorrhea); to assess associations of dysmenorrhea and period pain severity with adolescents missing regular activities because of their periods. STUDY DESIGN: Prospective, population-based cohort study; analysis of Longitudinal Study of Australian Children (LSAC) survey data. SETTING, PARTICIPANTS: Female adolescents in the nationally representative cross-sequential sample of Australian children recruited in 2004 for the Kinder cohort (aged 4-5 years at enrolment). Survey data from waves 6 (mean age 14 years), wave 7 (16 years) and wave 8 (18 years) were analysed. MAIN OUTCOME MEASURES: Severity of period pain during the preceding three months (very, quite, a little, or not at all painful); number of activity types missed because of periods; relationship between missing activities and period pain severity. RESULTS: Of the 1835 participating female members of the LSAC Kinder cohort at waves 6 to 8, 1600 (87%) responded to questions about menstruation during at least one of waves 6 to 8 of data collection. At wave 6 (14 years), 227 of 644 respondents (35%) reported dysmenorrhea, 675 of 1341 (50%) at wave 6 (16 years), and 518 of 1115 (46%) at wave 8 (18 years). Of the 366 participants who reported period pain severity at all three waves, 137 reported no dysmenorrhea at all three waves (37%), 66 reported dysmenorrhea at all three waves (18%), 89 reported increasing period pain over time (24%), and 38 reported declining pain (10%). At wave 6, 223 of 647 participants reported missing at least one activity because of their periods (34%), 454 of 1341 at wave 7 (34%), and 344 of 1111 at wave 8 (31%). Of the participants who experienced very painful periods, 72% (wave 6), 63% (wave 7), and 65% (wave 8) missed at least one activity type because of their periods, as did 45% (wave 6), 36% (wave 7), and 40% (wave 8) of those who experienced quite painful periods. CONCLUSIONS: A large proportion of adolescent girls in Australia experience period pain that affects their engagement in regular activities, including school attendance. Recognising adolescent period pain is important not only for enhancing their immediate quality of life with appropriate support and interventions, but also as part of early screening for chronic health conditions such as endometriosis.

Preliminary development of a measure of parental behavioral responses to everyday pains in young children: the PREP.

Introduction: Everyday pains are experienced frequently by young children. Parent responses shape how young children learn about and experience pain. However, research on everyday pains in toddlers and preschoolers is scarce, and no self-report measures of parent responses to their child's pain exist for this age group. Objectives: The objective of this study was to develop a preliminary self-report measure of parent behavioral responses to everyday pains in the toddler and preschool years (the PREP) and examine its relationship with child age, sex, and parent and child distress. Methods: Items for the PREP were based on a behavioural checklist used in a past observational study of caregiver responses to toddler's everyday pains. Parents (N = 290; 93% mothers) of healthy children (47.9% boys) between 18 and 60 months (Mage = 34.98 months, SD = 11.88 months) completed an online survey of 46 initial PREP items, demographic characteristics, and their child's typical distress following everyday pains. An exploratory factor analysis was performed on the PREP items that describe observable actions parents may take in response to their young child's everyday pains. Results: The final solution included 10 items across 3 factors: Distract, Physical Soothe, and Extra Attention and explained 60% of the model variance. All PREP subscales were related to child distress; only Physical Soothe and Extra Attention were related to parent distress. Conclusion: This study was a preliminary step in the development and testing of a new self-report measure of parental responses to everyday pains during early childhood.

The effectiveness of aerobic exercise and neck exercises in pediatric migraine treatment: a randomized controlled single-blind study.

BACKGROUND: Migraine is a prevalent condition with debilitating effects. In the context of pediatric migraine, there exists a notable scarcity of data regarding the effectiveness of exercise interventions. Furthermore, despite the prevalent occurrence of neck pain in these patients, the role of cervical musculoskeletal disorders in the etiology continues to be a debated topic. AIMS: This study is aimed at evaluating the effectiveness of aerobic and neck exercises for treatment of pediatric migraine. METHODS: This randomized, controlled, single-blind trial included 51 pediatric migraine patients. Participants were divided into two groups: one performing aerobic exercise and the other performing neck exercises. Assessments included attack frequency, severity, duration, and neck pain for over 3 months. RESULTS: Both exercise groups exhibited significant reductions in the attack frequency, severity, and duration. After 3 months, the aerobic exercise group showed a lower attack frequency than the neck exercise group. Subgroup analysis involving patients with neck pain showed similar neck pain reduction but favored the aerobic exercise group for attack frequency and severity. CONCLUSIONS: Aerobic and neck exercises are effective in reducing the symptoms of pediatric migraine. Aerobic exercise may be particularly beneficial for reducing the attack frequency. These findings contribute to the limited data on exercise interventions for pediatric migraineurs and highlight the importance of tailored exercise programs for managing this condition. Future studies should consider more extensive exercise modalities and include diverse patient cohorts. TRIAL REGISTRATION: Clinicaltrials.gov ID: NCT0606875.

Correlates of sexual function in women with acute lumbar disc herniation in Iran: a cross-sectional study.

Evidence suggests that lumbar disc herniation (LDH) influences sexual function to a great deal. However, most existing studies have been conducted on men. Thus, the current study aimed to assess sexual function and its correlates in women with acute LDH. This descriptive cross-sectional study was conducted on 350 women of reproductive age with acute LDH in Fasa, Iran in 2023. The mean score of female sexual function was 21.33 (3.38). Almost 80% of women had sexual dysfunction. Women scored lower on sexual desire and the higher on lubrication. As the severity of LDH increased, arousal, lubrication and sexual pain score decreased and low back pain (LBP) score increased (p < 0.05). The number of sexual activities after disc herniation was significantly lower in the women with sexual dysfunction (p < 0.001). Regression analysis showed a significant association between sexual dysfunction and LBP intensity (OR = 1.13, CI 1.02-1.26, p = 0.01) and lumbar disc herniation intensity (OR = 2.22, CI 1.07-4.62, p = 0.03). Lumbar disc herniation (LDH) may significantly affect women's sexual function. Severity of low back pain and severity of lumbar disc herniation were found to be risk factors for sexual dysfunction in this population.

The experiences of men in prison who do not receive visits from family or friends: A qualitative systematic review.

BACKGROUND: Visits present an opportunity for prisoners to preserve family ties and reduce isolation, but not all receive visits from family or friends whilst incarcerated. AIMS: To locate, appraise and synthesise qualitative data on the experiences of adult male prisoners (aged 18 years+) who do not receive prison visits from family or friends. METHODS: Nine electronic databases were searched from the date of their inception until March 2023. The quality of included studies was assessed using the Critical Appraisal Skills Programme checklist for qualitative studies, and data from the studies were synthesised using the thematic synthesis method. RESULTS: Eighteen studies from seven countries (the USA, the UK [England, Northern Ireland & Scotland], Canada, Netherlands and the Philippines) were eligible for inclusion. Three main themes emerged: (1) reasons for not receiving visits, (2) harmful effects of not receiving visits and (3) the value of volunteer visitor programmes. Practical problems were cited as interfering with visiting opportunities, but also some prisoners or families chose not to meet in prison. Loneliness and depression were extensively described as effects of not receiving visits. Qualities associated with volunteer visitors included raised self-esteem, improved mood and personal growth. CONCLUSION: Narratives of the experiences of adult men in prison without visits from family or friends suggest that not only the practical difficulties of imprisonment affect visiting; barriers that prisoners themselves impose would merit further exploration, as would family and relationship dynamics during incarceration and the emotional impact of prison visits, for both prisoners and their families. There are suggestions of therapeutic as well as humanitarian benefits from volunteer visiting programmes. There is a gap in the literature about any specific effect on rebuilding family relationships.

Discovery and optimization of (2-naphthylthio)acetic acid derivative as selective Bfl-1 inhibitor.

Bcl-2 anti-apoptotic protein family suppresses cell death by deploying a surface groove to capture the critical BH3 α-helix of pro-apoptotic members. Bfl-1 is a relatively understudied member of this family, though it has been implicated in the pathogenesis and chemoresistance of a variety of human cancers. Reported small molecular Bfl-1 inhibitors encountered the issue of either lack in potency or poor selectivity against its most homologous member Mcl-1. In order to tackle this issue, compound library was screened and a hit compound UMI-77 was identified. We modified its chemical structure to remove the characteristic of PAINS (pan-assay interference compounds), demonstrated the real binding affinity and achieved selectivity against Mcl-1 under the guidance of computational modeling. After optimization 15 was obtained as leading compound to block Bfl-1/BIM interaction in vitro with more than 10-fold selectivity over Mcl-1. We believe 15 is of great value for the exploration of Bfl-1 biological function and its potential as therapeutic target.

Poor quality of sleep and musculoskeletal pains among highly trained and elite athletes in Senegal.

BACKGROUND: Previous studies reported that poor sleep quality (PSQ) was associated with musculoskeletal pains (MSP) and poor physical performance in athletes. OBJECTIVE: The current study aimed at determining PSQ and its associations with MSP in some sub-Saharan athletes. METHODS: A cross sectional study was conducted among 205 highly trained and 115 elite athletes (aged: 25 ± 2 years, Body mass index: 22.8 ± 0.9 kg/m2) in Dakar, Senegal, during a competitive season in a variety of sport disciplines including athletics, basketball, football, rugby, wrestling, tennis. Quality of sleep and MSP were assessed using the French version Pittsburgh Sleep Quality Index (PSQI) and French version of Nordic questionnaire respectively. Pain on body joints during a week was defined as seven-day MSP (MSP-7d) and PSQ for a PSQI > 5. RESULTS: 27.8% (95%CI: 23.2-32.9) of the overall sample suffered PSQ, with 33.7% (95%CI: 24.7-44.0) in basketball and 24.7% (95%CI: 16.9-34.6) in football. According to athletic status and gender, PSQ was more prevalent among highly trained (66.3; 95%CI: 55.9-75.3) and men (69.7%; 95%CI: 59.5-78.7). Among athletes with PSQ 43.8% (95%CI: 33.9-54.2) suffered MSP-7d, with 36.6%; highly trained (95%CI: 23.7-42.9) and 28.1% female. Considering body region, hips/thigh (14.6%; 95% CI: 8.74-23.4) and upper back (13.5%; 95%CI: 7.88 -21, 1) were more affected. Basketball players were more affected from MSP (MSP-7d = 38.5%; 95%CI: 24. 9-54.1) on high on wrists/hands (MSP-7d = 44.4%; 95%CI: 18.9 -73.3; P = 0.04). Based on athletic status, MSP-7d were higher on highly trained necks (100%; 95%CI: 56.1-100; p = 0.04). PSQ was associated with basketball (OR: 3.062, 95%CI: 1.130-8.300, p = 0.02) compared to Athletic. PSQ and MSP-7d were associated on Wrist/hands (OR: 3.352, 95%CI: 1.235-9.099, p = 0.01), and at the upper back (OR: 5.820, 95%CI: 2.096-16.161, p = 0.0007). CONCLUSION: These results indicate that PSQ is considerable among Senegalese athletes and is associated with MSP during a week. Hence, we recommend to look for strategies optimizing good quality of sleep in order to reduce pains, to improve health.

Effect of Extracorporeal Shockwave Therapy on Pain Management of Patients with Post-Stroke Hemiplegic Shoulder Pain: A Prospective Randomized Controlled Trial.

Background: Post-stroke hemiplegic shoulder pain (HSP) is a common complication leading to significant activity limitation. Some approaches have been recommended for the management of HSP, and most of them have various adverse effects, while none were established to be effective. This study aimed to evaluate the effect of minimally invasive extracorporeal shockwave therapy (ESWT) on patients with HSP pain management. Materials and Methods: Using a single-blind, randomized clinical trial, 43 patients with HSP were randomly assigned to complete three focus ESWT sessions once a week and additional five radial ESWT sessions twice a week. Patients in the control arm received zero energy ESWT. Visual analog scale, passive range of motion (ROM), Fugl-Meyer upper extremity assessment (FMA-UE), and shoulder pain and disability scale (SPADI) were measured at baseline, at the end of the interventions, and within four and eight weeks' intervals to evaluate the pain, function, and ROM in the affected shoulder. Result: Both groups showed an improvement in pain scores on the fourth and eighth weeks visits (P-value <0.001). Intervention with ESWT could effectively lead to a less severe pain score compared to the control group (P-value <0.001). In the intervention group, the ROM improved in both passive abduction and forward flexion (P-value <0.05), but no significant change was observed in the control group (P-value >0.05). FMA-UE and SPADI did not differ significantly between groups. Conclusion: Based on the findings of this study, the combination of rESWT and focused ESWT can efficiently improve stroke-induced HSP.

Brain Wave Patterns in Patients With Chronic Low Back Pain: A Case-control Study.

Introduction: Research evidence indicates that maladaptive reorganization of the brain plays a critical role in amplifying pain experiences and pain chronification; however, no clear evidence of change exists in brain wave activity among patients with chronic low back pain (CLBP). The objective of this study was to assess brain wave activity in patients with CLBP, compared to healthy controls. Methods: Twenty-five patients with CLBP and twenty-four healthy controls participated in the study. A quantitative electroencephalography device was used to assess brain wave activity in eyes-open and eyes-closed (EO and EC) conditions. The regional absolute and relative power of brain waves were compared between the groups. Results: Our results showed a significant increase in the absolute power of theta (F=5.905, P=0.019), alpha (F=5.404, P=0.024) waves in patients with CLBP compared to healthy subjects in both EC and EO conditions. Patients with CLBP showed a reduced delta absolute power in the frontal region (F=5.852, P=0.019) and augmented delta absolute power in the central region (F=5.597, P=0.022) in the EO condition. An increased delta absolute power was observed in the frontal (F=7.563 P=0.008), central (F=10.430, P=0.002), and parietal (F=4.596, P=0.037) regions in patients with CLBP compared to the healthy subjects in the EC condition. In the EC condition, significant increases in theta relative power (F=4.680, P=0.036) in the parietal region were also found in patients with CLBP. Conclusion: The increased absolute power of brain waves in people with CLBP may indicate cortical overactivity and changes in the pain processing mechanisms in these patients. Highlights: Chronic low back pain (CLBP) increases the alpha, theta, and delta power in the brain.CLBP is associated with increased brain wave activity in the frontal, central, and parietal regions.Our findings suggest altered central pain processing in CLBP. Plain Language Summary: Traditional diagnosis and treatment of CLBP are mainly focused on peripheral pathology. But, the modern neuroscience approach to pain highlights the role of cortical plasticity in chronic musculoskeletal pain. In this regard, several studies found structural and functional changes in the brain in patients with chronic pain. Detailed knowledge about cortical changes in CLBP can improve our understanding of mechanisms involved in CLBP, opening a new window to better treatment of LBP (Low back pain). This study investigated brain wave activity in patients with CLBP compared to healthy individuals. Our findings suggest increased brain activity in various parts of the brain in patients with chronic LBP. This finding indicates that CLBP treatment should focus on both peripheral and cortical factors rather than local tissue damage.

Diagnosis of Rheumatoid Vasculitis From Ischemic Change in Hands: A Case Report.

Rheumatoid arthritis (RA) is a chronic inflammatory disorder with a wide clinical heterogeneity. Among its complications, rheumatoid vasculitis (RV) is notable for its severity and potential to involve multiple organ systems. A particularly serious manifestation of RV is ischemia, which is indicative of advanced vasculitic involvement and a significant risk of tissue damage. This case report describes an 83-year-old male with RA who presented with polyarticular joint pain and hand ischemia. Despite the initial diagnosis of RA exacerbation, worsening systemic symptoms without identifiable infectious causes and hypocomplementemia led to the diagnosis of RV exacerbation. Initial management with steroids showed temporary improvement. However, relapse after dose reduction prompted the administration of rituximab, an anti-cluster-of-differentiate-20 (anti-CD20) monoclonal antibody, which yielded favorable outcomes. This case underscores the importance of clinical vigilance in older patients with RA for signs, such as ischemic hands, emphasizing the pivotal role of early detection and intervention in RV management, particularly in community hospital settings.

Acute Onset Rheumatoid Vasculitis With Polyarthritis and Erythema: A Case Report.

We present the case of a woman in her 70s who was diagnosed with rheumatoid vasculitis (RV) after initially presenting with systemic joint pain and erythema. RV, a rare complication of rheumatoid arthritis, involves inflammation of blood vessels, leading to various skin manifestations. The patient's complaints included fever, generalized joint pain, and skin manifestations that initially resembled erythema multiforme. However, a skin biopsy revealed vasculitis, which guided the RV diagnosis. Although rheumatoid arthritis primarily affects the joints, systemic implications such as RV can arise in rare cases. This case underscores the importance of a holistic and meticulous diagnostic approach, especially in older patients, as early detection and treatment are crucial for managing disease progression and associated complications. Collaborative care involving multidisciplinary teams is vital to achieving optimal outcomes in complex cases.

Prevalence of Orthopedic Pains in Children and Adolescents: A Systematic Review and Meta-analysis.

Context: Musculoskeletal disorders are among the main causes of death and disability and can impose high costs on individuals and countries. Considering the importance of pain, the present meta-analysis study aimed to investigate the prevalence of orthopedic pains in Iranian children and adolescents. Methods: The present study was reported in line with PRISMA. The searching process was carried out using keywords, including adolescents, pain, youth, school-age children, shoulder pain, neck pain, shoulder, and neck, AND/OR operators for the articles published during 2000 and 2022 in Scopus, Embase, PubMed, Scientific Information Database, Magiran, International Statistical Institute, and Islamic World Science Citation Center databases. This study reviewed the articles that reported the prevalence of orthopedic pains (i.e., wrists/hands, shoulders, elbows, and knees) among the 5-18-year age group in Iran and extracted their results. Two researchers conducted the search quite independently and extracted the necessary data using a researcher-made checklist. The collected data were analyzed using Comprehensive Meta-Analysis software (CMA3). Results: Initially, 418 articles were identified, and 14 articles were entered into the systematic review stage. The prevalence rates of pains related to wrists/hands, shoulders, elbows, and knees were 6.6 (95% confidence interval [CI]: 3.2 - 13.0), 26.9 (95% CI: 17.0 - 39.7), 2.9 (95% CI: 1.3 - 6.3), and 6.6 (95% CI: 3.0 - 14.2), respectively. Conclusions: The prevalence of shoulder and knee pains in individuals under 18 years in Iran was high. Therefore, it is necessary to make necessary interventions and take preventive measures.

"Growing pains" in children and adolescents as an early symptom of migraine: A prospective study.

BACKGROUND: Children and adolescents may experience pain in the lower limbs, predominantly at the end of the day or during the night, without any relation to organic disease. These pains are often called "growing pains" (GP) by pediatricians and orthopedists. They are commonly attributed to rapid growth. OBJECTIVE: The aim of this study was to review and characterize GP in children and adolescents as a precursor/comorbidity with migraine. METHODS: The study was of a cross-sectional, prospective, longitudinal cohort, with group comparison. A sample of 100 children/adolescents born to mothers with migraine seen at a headache clinic was recruited in a random order chosen by lot, maintaining the ratio of 1:1 for the group with GP and the controls. Both groups were followed for a period of 5 years. RESULTS: After 5 years of follow-up, 78 patients completed the study, of which 42 were from the GP group and 36 were from the control group. Headache fulfilling the International Classification of Headache Disorders, 3rd edition diagnostic criteria for migraine without aura or probable migraine occurred in 32/42 (76%) of patients with GP and in 8/36 (22%) of controls (p < 0.001). In the sample that initially had "growing pains," these pains persisted in 6/42 (14%) and appeared in 14/36 (39%) of those who were previously asymptomatic (p = 0.026). CONCLUSIONS: Pain in the lower limbs of children and adolescents, commonly referred to as GP by pediatricians and orthopedists, may reflect a precursor or comorbidity with migraine.

Investigation of the Effect of Oral Selenium on the Reduction of Clinical Symptoms and Joint Pain in Patients With Rheumatoid Arthritis in the Iranian Population.

Rheumatoid arthritis (RA) is a common inflammatory joint disease. Because inflammation and nitrosative stress play an important role in the pathogenesis of RA, drugs that have antioxidant and anti-inflammatory effects can be effective as adjuvant treatment in these patients. Selenium is a compound that has been shown in recent studies to have anti-inflammatory and antioxidant effects. Therefore, the aim of this study was to investigate the effect of oral selenium on the reduction of clinical symptoms and joint pain in patients with RA. Fifty-one patients with moderate and severe RA were randomly divided into selenium and placebo groups. The first group of patients received selenium at a dose of 200 µg twice a day for 12 weeks along with standard RA interventions and treatments, and the second group received standard treatments of RA along with a placebo. Clinical symptoms were evaluated with standard indicators to evaluate disease activity before and after the intervention in the 12th week. Examination of clinical symptoms at the end of the study showed that in the selenium group and after 12 weeks, a reduction in clinical symptoms and joint pain were observed, which was statistically significant compared with before the study began. Meanwhile, no significant changes were observed in the patients of the placebo group in terms of reducing symptoms and joint pains. A dose of 200 µg of oral selenium twice a day for 12 weeks can significantly reduce clinical symptoms and joint pain in patients with RA.

Prevalence of growing pains in a general paediatric OPD: A descriptive, observational and cross-sectional study.

Context: Growing pain (GP) is a common presentation in primary care settings. Aims: To find out the prevalence of GP and to observe its characteristics and associations. Settings and Design: General paediatric outpatient department (OPD). Methods and Material: Children coming to the general paediatric OPD of a tertiary centre in India between April 2019 and March 2020 for 'chronic leg pains' were screened with Peterson's criteria. Patients with systemic illness were excluded. All received vitamin D and calcium supplementation. Patients with haemoglobin less than 11 gm% received additional 3 mg/kg iron supplementation. Then, patients were asked for follow-up. Statistical Analysis Used: Chi-square test. Results: A total of 333 children were diagnosed as GP out of the total OPD attendance of 26750. The prevalence was 1.24% and 72.7% among the children with chronic leg pain. Highest prevalence was in winter (1.74%). The mean age of the patients was 7.88 years. The mean duration of symptoms was 10.92 months. After 3 months, 267 patients could be followed up. Seventy-two out of 107 (67.3%) children, who received iron became symptom-free. Only 43 (28.8%) patients became symptom-free out of 160, who received only calcium and vitamin D3 and did not receive iron. The difference was highly significant statistically (P < 0.0001). Conclusions: The prevalence of GP in the OPD was 1.24% and 72.7% among the children with chronic leg pain. Iron supplementation along with vitamin D3 and calcium was associated with faster resolution of the symptoms.
