Assessing Osteoporosis Knowledge and Beliefs Among Adults Living in Saudi Arabia: A Cross-Sectional Study.

BACKGROUND: Knowledge and beliefs about osteoporosis have been considered one of the vital parts of early prevention against it. OBJECTIVES: This study aimed to evaluate knowledge and beliefs toward osteoporosis using the Osteoporosis Knowledge Assessment Tool (OKAT) and Osteoporosis Health Belief Scale (OHBS) questionnaires among the public in Jeddah, Saudi Arabia. METHODS: This cross-sectional study was conducted from March 2019 to April 2019 among adults aged 15 years and above. A validated questionnaire was allocated electronically to the participants through social platforms (such as Twitterand WhatsApp) using a convenience sampling technique. RESULTS: A total of 754 participants completed the questionnaire. The majority were females 481 (63.8%). A total of 34 (4.1%) have not heard about osteoporosis before. Respondents scored a total mean of 7.92±3.0for the OKAT questionnaire and a mean score of 126.74±22.38for the OHBS questionnaire. These two scores were significantly associated with age groups and gender (P < 0.05). CONCLUSION: Although there is a relative increase in the knowledge of our sample, the belief towardosteoporosis is evidently lower. Therefore, implementing educational programs that tackle belief perception and other preventive measures such as healthy eating habits, physical activities, and educational materials are needed in the future.

Efficacy of Platelet-Rich Plasma on Pain and Function in the Treatment of Knee Osteoarthritis: A Prospective Cohort Study.

Background Osteoarthritis (OA) is a degenerative disease commonly affecting the knee joints. It affects patients socially, psychologically and economically and rates of the disease have been increasing due to obesity and old age. Regardless of choosing a medically conservative approach, it is a challenge in the long term to provide OA patients efficient treatment with minimal side effects and long-term efficiency. Platelet-rich plasma (PRP) is a convenient, low-cost and affordable treatment technique used in treating knee OA with encouraging efficient and safe outcomes. In this study we will investigate the effect of PRP on knee OA. Methods This is a prospective cohort study involving 252 patients with different OA grades. The Kellgren and Lawrence (K&L) system was used in classifying the affected knee by degenerative cartilage lesions as well as early and severe OA. All patients with a diagnosis of knee OA were screened in every visit before the injection, the pain was assessed by the 0-10 Numeric Rating Scale (NRS), and knee range of motion including flexion and extension was assessed by goniometer. Follow-up appointments were done on three-month intervals for a total of three visits for evaluation. Injection of PRP was given to all the patients with a maximum of four injections. The results were evaluated statistically according to the total number of follow-up visits. Results In grade II patients, the pain improved with the visits and the maximum improvement in flexion degree was noticed in patients who came for a total of three follow-up visits. In grade III patients, the most improvement in pain was in patients who came for three follow-up visits, while the most improvement in flexion degree was in patients who came for a total of two follow-up visits. Patients with grade IV who came for three follow-up visits showed the most improvement in pain and degree of flexion. Conclusions Intra-articular injections gave significant pain and flexion improvement in grades II, III and IV in OA patients, especially with multiple injection in the short-term follow-up. As a result, recommendation of repeated multiple injections up to four times is efficient in providing long time relief in knee OA.

Unusual Case of Gouty Arthritis of the Second Distal Interphalangeal Joint (Second Toe).

Gout is one of the most common diseases affecting men globally due to the spread of unhealthy dietary habits, kidney disease, and the use of diuretics. It is characterized as having monosodium crystals depositions in the synovial fluid, which causes an inflammatory response and painful joints. Most of the time, it can be found affecting the first metatarsophalangeal joint or other large joints in concurrence with other disorders. Non-steroidal anti-inflammatory drugs (NSAIDs), colchicine, and steroids have been known to suppress such events in most cases without the need for any surgical intervention. We present a case of a 44-years-old medically free healthy male who presented with a case of gouty arthritis in the second distal interphalangeal joint. Initially, colchicine treatment was given along with NSAIDs, but symptoms failed to subside. After a persistent increase of swelling and pain, the surgical evacuation was sought to reduce the pain and exclude any other causes of arthritis. Histopathology report confirmed the presence of monosodium urate crystals without any signs of infection. In conclusion, surgical intervention of gouty arthritis can be beneficial in cases of persistent pain and increasing rate of swelling despite the medicinal trial, especially in unusual cases of gouty arthritis such as gout of the second metatarsophalangeal joint.

The association between smartphone addiction and thumb/wrist pain: A cross-sectional study.

Many smartphone users experience pain in the thumb/wrist. This pain can be due to certain types of hand injuries as well as inflammation of the extensor pollicis brevis and the abductor pollicis longus tendon sheaths, known as De Quervain tenosynovitis. The objective of this study was to evaluate the association between smartphone addiction and wrist/thumb pain and to determine the severity of the pain, as well as to calculate the prevalence of De Quervain tenosynovitis among medical students at King Abdulaziz University (KAU) in Jeddah.A total of 387 medical students were enrolled. The smartphone addiction scale-short version (SAS-SV) was used to divide participants into the smartphone addict group and non-addict group. Both groups completed the self-administered patient-rated wrist and hand evaluation (PRWHE) questionnaire to evaluate wrist/hand pain. The Finkelstein test was administered to those who reported pain in the thumb/wrist.Two hundred fifty-seven (66.4%) participants were smartphone addicts; 74 (19.1%) had a positive Finkelstein test. There was a significant correlation between smartphone addiction and high PRWHE scores (P = .036).Our study found the prevalence of smartphones addiction among university students to be high (66%), furthermore a correlation between heavy smartphones usage and hand pain was found which indicates that heavy usage of these devices can cause subclinical effects on the human hand.

Relationship between Body Mass Index and T-Scores of Bone Mineral Density in the Hip and Spine Regions among Older Adults with Diabetes: A Retrospective Review.

Diabetes mellitus (DM) cases are increasing worldwide, especially in Saudi Arabia. Previous studies suggested a positive relationship between body mass index (BMI) and bone mineral density (BMD) levels. Generally, patients with low BMI (<18.5 kg/m2) have reduced BMD levels and, thus, low T-scores; hence, they are categorized as osteopenic or osteoporotic. In this study, we aimed to determine whether a relationship between BMI and BMD T-scores in the hip and spine regions of patients with diabetes exists. This retrospective record review investigated older adult patients with diabetes in King Abdulaziz University Hospital (n=198; age 50-90 years) who underwent BMD scan between January 1, 2016, and June 25, 2018, regardless of their sex but limited to type 2 DM. The height and weight of all subjects were recorded, and BMI was calculated and categorized. We used SPSS version 21 for data analysis; measures of central tendencies, Pearson's correlations, chi-square tests, and independent t-tests were employed. We found positive relationships between BMI and BMD T-scores in the hip and spine regions (right femoral neck: R=+0.214, P ≤ 0.002; total right hip: R=+0.912, P ≤ 0.001; left femoral neck: R=+0.939, P ≤ 0.001; total left hip: R=+0.885, P ≤ 0.001; and total lumbar region: R=+0.607, P ≤ 0.001). Low BMI (<18.5 kg/m2) could be a risk factor for osteoporosis, whereas normal/high BMI could be protective against osteoporosis among adults with diabetes.

Bariatric surgery improves knee function and not knee pain in the early postoperative period.

BACKGROUND: Obesity remains the strongest predictor of knee osteoarthritis (OA). Studies have reported improvement in knee pain and function post-bariatric surgery secondary to weight loss and reduced mechanical loading, yet others found increased rates of total knee arthroplasty (TKA) in that patient population. To address this controversy, our study aimed to further assess the effect of surgically induced, "rapid" weight loss on knee pain and function. METHODS: Obese patients with chronic knee pain, who were undergoing bariatric surgery, were enrolled and surveyed preoperatively and 3 months postoperatively. Our outcome measures were knee pain and knee function, assessed by a knee injury and osteoarthritis outcome score (KOOS). The paired t test was used to compare pre- and postoperative KOOS scores. Pearson correlation coefficient was used to test the correlation between change in body mass index (BMI) with knee function, pain, and stiffness. RESULTS: A total of 30 patients was included in the study. The mean age was 35 years, with a mean preoperative BMI of 42.8. The mean difference in BMI at 3 months was 8.4 (SD3). There was a significant improvement in KOOS, - 23.2 (± 20) points, p < 0.01, most pronounced in knee function related to sport activities, with a difference of - 22.6 points, p < 0.01. Knee pain scores improved but did not reach statistical significance. CONCLUSION: Surgically induced rapid weight loss significantly improved knee function, particularly related to sports. However, there was no change in knee pain. This may be related to increased high-impact knee exercises and reduced lean mass. Tailored exercise programs for bariatric surgery patients postoperatively, may improve symptoms and decrease the need for knee replacements in the long term.

Acute Cholecystitis Following Total Knee Replacement: A Case Report and Literature Review.

INTRODUCTION: Infection poses a substantial challenge after joint replacement. CASE PRESENTATION: We report a 53-year-old female with multiple co-morbidities, who underwent unilateral total knee arthroplasty. Her postoperative course was complicated by acute cholecystitis necessitating cholecystectomy. CONCLUSION: In patients who require joint replacement surgery, careful and detailed preoperative assessment is important to identify those at risk for this complication in order to provide timely treatment.

A preliminary exploration of ulnar variance in healthy wrists at a tertiary hospital in Jeddah.

OBJECTIVES: To gain preliminary insight by exploring ulnar variance changes in a Saudi-based sample.   METHODS: This 6-month (December 2013 to June 2014) cross-sectional study was conducted on a randomly selected healthy adult volunteers with a sample size of 104, at King Abdulaziz University Hospital, Jeddah, Saudi Arabia. Posteroanterior (PA), anteroposterior (AP), and PA grip views are taken. The variables of interest were the PA, AP, and PA fist measurements of both right and left wrists. An independent t-test was used to compare means between groups. RESULTS: A total of 104 volunteers were recruited. Among 17 participants who had a negative ulnar variance on right PA views, a significantly high proportion (n=9; 56.2%) maintained a negative value on fist views; 7 participants (43.8%) had a neutral ulnar variance while none (0%) had a positive value (p less than 0.001). Similarly, a significant proportion of participants who had neutral, or positive values on right PA views maintained the same values on right fist views (p less than 0.001). On radiographs of the right wrist, the ulnar variance decreased with a change in wrist position, with an absolute difference in magnitude of 2.13 (p less than 0.001) between PA and AP views. Similarly, the ulnar variance on the left side decreased significantly between PA and AP views (absolute difference in magnitude, 1.68; p less than 0.001).   CONCLUSIONS: Ulnar variance changes in our sample are similar to what is reported in the literature.

Tuberculous Dactylitis : Case Presentation and Functional outcome.

INTRODUCTION: Skeletal tuberculosis involving the small bones is less common than pulmonary tuberculosis. Tuberculous dactylitis involves the short tubular bones of the hands and feet more commonly in children. The bones of the hands are the one's more frequently affected than bones of the feet, with the proximal phalanx of the index and middle fingers as the commonest sites for infection. Spread to the skeletal system occurs during the initial infection via the lympho-haematogenous route. The radiographic features of cystic expansion have led to the name "Spina Ventosa" for tuberculous dactylitis of the short bones. We report a case of tuberculous dactylitis in the right little finger. CASE PRESENTATION: We describe a 36-year-old woman, who presented with a 12-month history of painless swelling of her right little finger associated with fever and night sweats. Her history was remarkable for persistent productive cough. On examination, her investigation reports and radiographs correlated with the symptoms of tuberculosis, suggestive of tuberculous arthritis. Magnetic resonance imaging of the hand was suggestive of osteomyelitis. Histopathological examination revealed chronic granulomatous inflammation that was consistent with osteomyelitis of the bone due to tuberculosis. However, acid-fast bacilli were not identified. Full course of anti-tuberculosis regimen was commenced. Monthly follow-up and radiographic examinations revealed improvement of the patient under this treatment. She also achieved a good functional outcome. CONCLUSION: Tuberculosis should be considered in patients with unusual soft tissue or skeletal lesions in order to make an early diagnosis and to achieve a good functional outcome. Although tuberculosis of the hand has a varied presentation, the majority of lesions respond to conservative treatment, as anti-tuberculosis chemotherapy is the cornerstone in the management of skeletal tuberculosis.

A prospective metal ion study of large-head metal-on-metal bearing: a matched-pair analysis of hip resurfacing versus total hip replacement.

The current study measured ion release among large-head metal-on-metal hip bearings. Twenty-six patients with a modular, Profemur® TL with A-Class® big femoral head total hip replacement were matched (gender, femoral size, BMI) with a group of 26 patients with the Conserve® Plus implant hip resurfacing. Compared with HR patients, THR patients had higher median serum cobalt ion levels at 6 months (3.26 vs 1.12 µg/L, P = .002) 1 year (4.51 vs 1.02, P = .002), and 2 years (3.77 vs 1.22, P<.001) following surgery. No differences in chromium ions were observed. Further research is required to determine the clinical significance of elevated serum cobalt ions.

Biomechanical analysis of lateral pin placements for pediatric supracondylar humerus fractures.

AIM: Several clinical studies have shown that lateral pinning alone is of equal stability to crossed pins in the treatment of supracondylar fractures. The aim of this study was to compare the stability of parallel and varied divergent lateral pin configurations to provide an easily reproducible technique for optimal pin placement. METHODS: Twelve third-generation synthetic composite humeri were osteotomized at the level of the coronoid and olecranon fossae to simulate a humeral supracondylar fracture. Each fracture was reduced and fixed using two 1.6 mm (0.062 inches) Kirschner wires (1 fixed, 1 varied) in 4 different positions (from parallel to divergent with respect to fixed wire), and sequentially tested in extension, varus, and valgus as well as internal and external rotations using an MTS 858 Minibionix materials testing load frame (MTS Corporation, Eden Prairie, MN). A 2-way analysis of variance was carried out to compare construct stiffness in all 5 modes of testing according to both pin position and testing sequence. A level of P<0.05 was considered statistically significant. RESULTS: The best torsional, valgus, and extension resistances were found with position 4, which was the most divergent configuration. For both internal and external rotations, position 4 showed statistically higher stiffness as compared with all other configurations (P<0.05). In resistance to extension, both positions 3 and 4 were stiffer than either position 1 or 2 (P<0.05). For resistance in varus testing, position 3 showed statistically greater stiffness than all other pin positions (P<0.05). Although there was no statistical difference between all the 4 positions in valgus testing, position 4 showed greater resistance when compared with other positions. CONCLUSIONS: The lateral pin placed parallel to the metaphyseal flare of the lateral humeral cortex, in combination with a second diverging pin crossing the fracture site at the medial edge of the coronoid fossa (position 4), provided the optimum fixation for supracondylar fractures of the humerus. CLINICAL RELEVANCE: Using these readily available landmarks, the treating surgeon can reproducibly provide appropriate pinning treatment for most of these fractures.
