SPECIFIC SITES OF BONE EXPANSION DEPEND ON THE LEVEL OF VOLLEYBALL PRACTICE IN PREPUBESCENT BOYS

The purpose of this study was to investigate the effect of 18 months of high and low levels of volleyball practice on bone acquisition. 130 prepubescent boys (mean age 11.4 ± 0.7) were divided into a high-level training group (HLG), low-level training group (LLG), and controls. Bone mineral content (BMC) and bone area at the whole body, lumbar spine L2-L4, femoral neck of the dominant leg, and right and left radius were measured using dual-photon X-ray absorptiometry. Enhanced BMC resulted from high-training volleyball activity in all measured sites except the third left and right distal radius, which is not modified by low-level training in prepubescent players but it was accompanied by a bone area expansion in radius and weight-bearing sites for the HLG, and in legs, whole right and left radius for the LLG. Significant improvement of skeletal tissues is associated with the intensity and duration of volleyball training

Bone metastasis as the first sign of gastric cancer

The skeleton is a common metastatic site for visceral carcinomas. However, the presentation of gastric cancer as bony metastases without preceding gastrointestinal symptoms is rare which has been infrequently reported in the literature. We report an infrequent case of a 60-year-old patient diagnosed having a gastric carcinoma with bone metastasis as the first evidence. She has consulted with worsening backache which started two months priorly

Sacroiliites infectieuses dans le centre tunisien: étude rétrospective de 25 cas

Les sacroiliites infectieuses sont rares mais peuvent se compliquer de séquelles fonctionnelles invalidantes. L’objectif de cette étude était de écrire les caractéristiques cliniques et bactériologiques des sacroiliites infectieuses chez les patients suivis à Sousse, Centre Tunisien. Etude rétrospective, descriptive, des cas de sacroiliites infectieuses chez les patients hospitalisés à Sousse entre 2000 et 2015. Le diagnostic a été retenu devant des signes cliniques, d’imagerie, et microbiologiques évocateurs. Vingt-cinq patients, 10 hommes et 15 femmes, d’âge moyen 41 ans (19-78) ont été inclus. Les sacroiliites étaient dues à des bactéries pyogènes dans 14 cas (56%), brucelliennes dans 6 cas (24%), et tuberculeuses dans 5 cas (20%). La durée moyenne d’évolution était de 61, 45 et 402 jours respectivement. Les signes cliniques les plus fréquents étaient les douleurs fessières (92%) et la fièvre (88%). La radiographie standard était anormale dans 75% des cas. La TDM et l’IRM sacro-iliaques dans tous les cas. Le diagnostic a été confirmé bactériologiquement dans 24 cas (96%). La durée moyenne d’antibiothérapie était de 83 jours dans les sacroiliites à pyogènes, et de 102 jours dans les SI brucelliennes. L’évolution était favorable chez 12 patients (48%), 9 patients (36%) ont gardé une douleur sacro-iliaque séquellaire, et 4 patients (16%) sont décédés. Dans notre étude, la durée d’évolution de la sacroiliite infectieuse ne permettait pas de prédire la bactérie responsable, d’où la nécessité d’obtenir une documentation bactériologique afin de prescrire une antibiothérapie appropriée.Pan African Medical Journal 2016; 2

Reparative radiological changes of hip joint after TNF inhibitors in ankylosing spondylitis

Background: Hip involvement in ankylosing spondylitis (AS) is a common extraspinal arthritic manifestation, which is associated to a worse functional outcome. Little data are available on the effectiveness of conservative treatment strategies. The TNF inhibitors have been proven effective on AS activity parameters. Their structural effect on hip disease however, little is studied. Case presentation: We describe four new cases of reparative changes of a damaged hip joint after treatment with TNF inhibitors. The average of age was 32.5 (27- 36) years. There were 3 men and 1 woman. Hip involvement was bilateral in all cases. Etanercept was prescribed in 3 cases and infliximab in 1 case. At baseline, all patients had a painful and limited hip with high disease activity and an important functional impairment. After an average of 5.5 years of treatment with TNF inhibitors, the BASRI hip evaluated in antero-posterior x-rays of the pelvis remained unchanged at 2.4. The average of mean hip joint space was 2.9mm (2.3-3.6). A widening in hip joint space was observed in all cases with less subchondral cysts. Conclusion: TNF inhibitors seem to be effective on hip joint disease in patients with AS

Musculoskeletal ultrasonography of the Achilles tendon and plantar fascia in spondyloarthritis patients

Aim of the work: To assess the frequency and severity of peripheral enthesitis in spondyloarthritis (SpA) patients using musculoskeletal ultrasound (MSKUS) in B mode associated with power Doppler (PD) compared to a group of patients with mechanical low back pain (M-LBP). Patients and methods: The study included 40 SpA patients and 20 M-LBP patients as a control group. Ultrasound (US) in B mode and PD was performed at Achilles tendon (AT) and plantar fascia (PF). Results: The mean age of SpA patients was 41.9 ± 14.3 years and disease duration 8.4 ± 5.8 years. Axial form was found in 36 cases (90%) and peripheral form in 4 (10%). The mean ESR was 28.3 ± 23.2 mm/1sth and the CRP was 22.9 ± 31.2 mg/l. In SpA patients 109/160 (68.1%) of the assessed entheseal sites were significantly abnormal compared to 27/80 (33.8%) in M-LBP patients (AT p < .0001 and PF p = .02). Compared to the M-LBP patients, a significant difference was found in AT for hypoechogenicity (p = .006) and bone erosion (p = .005) and at both entheses for cortical hypervascularisation (AT: p < .0001 and PF: p = .03). Otherwise, in SpA patients, 60.2% (53/88) of non tender entheses showed at least one ultrasound abnormality compared to 77.8% (56/72) of tender entheses. A significant correlation was identified between clinical and ultrasound assessment (r = 0.4, p = .01). Conclusion: The frequency of enthesitis was high among SpA compared with M-LBP patients and AT was the most affected enthesis. Abnormal vascularization in the cortical bone insertion of entheses was detected especially in SpA patients, and there was great evidence of subclinical enthesitis.
