Musculoskeletal pain in female asylum seekers and hypovitaminosis D3

Résumé de l'article L'hypovitaminose D3 est bien connue et courante chez la population âgée en Occident. Toutefois, elle est probablement sous-diagnostiquée chez les jeunes femmes immigrantes, bien qu'elle soit bien documentée, principalement en Angleterre dans la population Indo-Pakistanaise. Lorsque ce déficit est diagnostiqué, le traitement substitutif est simple et bon marché. Nous avons suspecté une haute prévalence chez de jeunes femmes requérantes d'asile, surtout chez celles provenant de cultures différant quant à l'exposition solaire et la diète. Nous publions donc une série de 11 cas de patientes avec une hypovitaminose D symptomatique issues de la consultation générale de la Policlinique Médicale Universitaire. Toutes les patientes présentaient une anamnèse d'une faible exposition solaire et de douleurs osseuses diffuses, d'une fatigue, d'une faiblesse musculaire ou des modifications de la marche. Toutefois, les premiers diagnostics évoqués par les médecins étaient une possible somatisation (3 patientes), des douleurs dorso-lombaires chroniques (4 patientes) et des symptômes somatiques multiples et inexpliqués (3 patientes). Le diagnostic a été posé d'emblée chez une patiente seulement. La durée moyenne des plaintes avant la pose du diagnostic était de 38 mois et 5 jours. Avec le traitement de cholecalciférol et de calcium, les symptômes disparaissaient entre 1 et 3 mois, chez une patiente ils ont duré sept mois. Le taux moyen de 250H vitamine D3 était de 10.9 nmol/l (IR 21-131). Le taux moyen de calcium était de 2.19 mmol/l (2.15-2.55) et quatre patientes présentaient une hypocalcémie. Nous pensons donc que les femmes requérantes d'asile sont à risque d'une durée prolongée de symptômes, de part la possible haute prévalence de cette condition et la difficulté chez les médecins à la reconnaître. Le diagnostic d'hypovitaminose devrait être recherché chez les femmes requérantes d'asile souffrant de douleurs musculo-squelettiques de longue durée. Le premier diagnostic souvent évoqué, dans un contexte psychosocial souvent difficile, était de l'ordre d'un trouble somatoforme douloureux ou de somatisations. Toutefois, les douleurs liées à l'hypovitaminose D3 sont relativement bien définies ; elles sont symétriques, osseuses, débutent souvent dans la région lombaire pour ensuite s'étendre au bassin, aux membres inférieures proximalement et à la cage thoracique. Le traitement substitutif est simple, peu onéreux et il serait judicieux d'initier d'autres études pour évaluer le besoin d'une substitution de routine dans la population présentée. Abstract: Deficiency of vitamin D, which can lead to osteomalacia, is common in elderly patients in Western countries. However, it is still widely underdiagnosed in young immigrant women, even though the condition has been extensively reported in the immigrant Indo- Asian population in the United Kingdom since the 1960s. A recent study reports an average 59 months before diagnosis was established, and another study found a prevalence of 78% of hypovitaminosis D3 (compared with 58% in controls) in an Indo-Asian population attending a UK rheumatology clinic. When recognised, hypovitaminosis D3 is easily treatable. A study on osteomalacic myopathy in veiled Arabic women in Denmark found that muscle strength returned to normal (except in maximal voluntary con-traction) after six months' treatment. We expected to see this disease in female asylum seekers, especially in those from societies with different customs regarding exposure to sunlight and diet We report 11 cases of symptomatic hypovitaminosis D3 in female asylum seekers (table 1). We focus on the pathology encountered by the primary care doctors caring for these 11 patients, the length of time between the appearance of symptoms, and the establishment of the diagnosis of hypovitaminosis D3 as well as the women's response to treatment by the improvement of a wide range of clinical symptoms-bone pain, muscular weakness, and fatigue.

Advanced age increases the failure rate of non-operative management of blunt splenic injuries

Introduction: Non-operative management (NOM) of blunt splenic injuries in hemodynamically stable patients is nowadays considered the standard treatment. Material and Methods: The aim was to clarify the criteria used for primary operative management (OM) and planned NOM. Furthermore, the study aimed to identify risk factors for failure of NOM. All adult patients with blunt splenic injuries treated from 2000-2008 were reviewed and a logistic regression analysis employed. Results: There were 206 patients (146 men, 70.9%). Mean age was 38.2 ± 19.1 years. The mean Injury Severity Score (ISS) was 30.9 ± 11.6. The American Association for the Surgery of Trauma (AAST) classification of the splenic injury was: grade I, n = 43 (20.9%); grade II, n = 52 (25.2%); grade III, n = 60 (29.1%), grade IV, n = 42 (20.4%) and grade V, n = 9 (4.4%). 47 patients (22.8%) required immediate surgery (OM). More than 5 units of red cell transfusions (odds ratio [OR] 13.72, P < 0.001), a Glasgow Coma Scale < 11 (OR 9.88, P = 0.009) and age ? 55 years (OR 3.29, P = 0.038) were associated with primary OM. 159 patients (77.2%) qualified for a non-surgical approach (NOM), which was successful in 89.9% (143/159). The overall splenic salvage rate amounted to 69.4% (143/206). Multiple logistic regression analysis found age ? 40 years to be the only factor significantly and independently related to the failure of NOM (OR 13.58, P = 0.001). Conclusion: Advanced age is associated with an increased failure rate of NOM in patients with blunt splenic injuries.

PET-measured responses of MBF to cold pressor testing correlate with indices of coronary vasomotion on quantitative coronary angiography.

The aims of this study were to determine whether responses in myocardial blood flow (MBF) to the cold pressor testing (CPT) method noninvasively with PET correlate with an established and validated index of flow-dependent coronary vasomotion on quantitative angiography. METHODS: Fifty-six patients (57 +/- 6 y; 16 with hypertension, 10 with hypercholesterolemia, 8 smokers, and 22 without coronary risk factors) with normal coronary angiograms were studied. Biplanar end-diastolic images of a selected proximal segment of the left anterior descending artery (LAD) (n = 27) or left circumflex artery (LCx) (n = 29) were evaluated with quantitative coronary angiography in order to determine the CPT-induced changes of epicardial luminal area (LA, mm(2)). Within 20 d of coronary angiography, MBF in the LAD, LCx, and right coronary artery territory was measured with (13)N-ammonia and PET at baseline and during CPT. RESULTS: CPT induced on both study days comparable percent changes in the rate x pressure product (%DeltaRPP, 37% +/- 13% and 40% +/- 17%; P = not significant [NS]). For the entire study group, the epicardial LA decreased from 5.07 +/- 1.02 to 4.88 +/- 1.04 mm(2) (DeltaLA, -0.20 +/- 0.89 mm(2)) or by -2.19% +/- 17%, while MBF in the corresponding epicardial vessel segment increased from 0.76 +/- 0.16 to 1.03 +/- 0.33 mL x min(-1) x g(-1) (DeltaMBF, 0.27 +/- 0.25 mL x min(-1) x g(-1)) or 36% +/- 31% (P <or= 0.0001). However, in normal controls without coronary risk factors (n = 22), the epicardial LA increased from 5.01 +/- 1.07 to 5.88 +/- 0.89 mm(2) (19.06% +/- 8.9%) and MBF increased from 0.77 +/- 0.16 to 1.34 +/- 0.34 mL x min(-1) x g(-1) (74.08% +/- 23.5%) during CPT, whereas patients with coronary risk factors (n = 34) revealed a decrease of epicardial LA from 5.13 +/- 1.48 to 4.24 +/- 1.12 mm(2) (-15.94% +/- 12.2%) and a diminished MBF increase (from 0.76 +/- 0.20 to 0.83 +/- 0.25 mL x min(-1) x g(-1) or 10.91% +/- 19.8%) as compared with controls (P < 0.0001, respectively), despite comparable changes in the RPP (P = NS). In addition, there was a significant correlation (r = 0.87; P <or= 0.0001) between CPT-related percent changes in LA on quantitative angiography and in MBF as measured with PET. CONCLUSION: The observed close correlation between an angiographically established parameter of flow-dependent and, most likely, endothelium-mediated coronary vasomotion and PET-measured MBF further supports the validity and value of MBF responses to CPT as a noninvasively available index of coronary circulatory function.

Soil Water Potentials and Capsicum annuum L. under Salinity

ABSTRACT Investigations into water potentials in the soil-plant system are of great relevance in environments with abiotic stresses, such as salinity and drought. An experiment was developed using bell pepper in a Neossolo Flúvico (Fluvent) irrigated with water of six levels of electrical conductivity (0, 1, 3, 5, 7 and 9 dS m-1) by using exclusively NaCl and by simulating the actual condition (using a mixture of salts). The treatments were arranged in a randomized block design, in a 6 × 2 factorial arrangement, with four replicates. Soil matric (Ψm) and osmotic (Ψo) potentials were determined 70 days after transplanting (DAT). Soil total potential was considered as the sum of Ψm and Ψo. Leaf water (obtained with the Scholander Chamber) and osmotic potentials were determined before sunrise (predawn) and at noon at 42 and 70 DAT. There were no significant differences between the salt sources used in the irrigation water for soil and plant water potentials. The supply of salts to the soil through irrigation water was the main factor responsible for the decrease in Ψo in the soil and in bell pepper leaves. The total potential of bell pepper at predawn reached values of -1.30 and -1.33 MPa at 42 and 70 DAT, respectively, when water of 9 dS m-1 was used in the irrigation. The total potential at noon reached -2.19 MPa. The soil subjected to the most saline treatment reached a water potential of -1.20 MPa at 70 DAT. There was no predawn equilibrium between the total water potentials of the soil and the plant, indicating that soil potential cannot be considered similar to that of the plant. The determination of the osmotic potential in the soil solution should not be neglected in saline soils, since it has strong influence on the calculation of the total potential.

Does altering inclination alter effectiveness of treadmill training for gait impairment after stroke? A randomized controlled trial.

Objective: To assess whether a downhill walking training programme is more effective than the same amount of training applied uphill in chronic stroke survivors. Design: Randomized, single-blind study. Setting: Outpatient rehabilitation service. Methods: Thirty-eight adults with hemiplegia from stroke lasting more than three months were randomly allocated to one of the two groups: 'UP' - 45 minutes of physical therapy + 30 minutes of treadmill with 5% ascending slope; and 'DOWN' - 45 minutes of physical therapy + 30 minutes of treadmill with 5% descending slope. Both groups were treated 5 times a week for six weeks. Patients were evaluated before treatment, at the end of treatment and after three months. Outcome measures: Primary outcome measure was the number of patients showing an improvement in 6-minute walking test (6MWT) greater than 50 m. Secondary outcome measures were: (1) number of patients showing a clinically relevant improvement of gait speed during 10-m walking test (10mWT); (2) number of patients showing an improvement in timed up and go (TUG) greater than minimal detectable change. Results: Both groups had a significant improvement after treatment and at follow-up. At the end of treatment, compared to UP group, more patients in the DOWN group showed clinically significant improvements in primary and secondary outcomes (16/19 patients for 6MWT, 11/19 patients for 10mWT and 9/19 patients for TUG compared with 3/19, 4/19 and 2/19 patients, respectively, P < 0.01). At follow-up, results were similar except for 10mWT. Conclusions: In chronic stroke patients, downhill treadmill training produces a bigger effect than uphill training.

Outcome of long-axis percutaneous sacroplasty for the treatment of sacral insufficiency fractures.

Our aim was to assess the clinical outcome of patients who were subjected to long-axis sacroplasty for the treatment of sacral insufficiency fractures. Nineteen patients with unilateral (n = 3) or bilateral (n = 16) sacral fractures were involved. Under local anaesthesia, each patient was subjected to CT-guided sacroplasty using the long-axis approach through a single entry point. An average of 6 ml of polymethylmethacrylate (PMMA) was delivered along the path of each sacral fracture. For each individual patient, the Visual Analogue pain Scale (VAS) before sacroplasty and at 1, 4, 24 and 48 weeks after the procedure was obtained. Furthermore, the use of analgesics (narcotic/non-narcotic) along with the evolution of post-interventional patient mobility before and after sacroplasty was also recorded. The mean pre-procedure VAS was 8 +/- 1.9 (range, 2 to 10). This rapidly and significantly (P < 0.001) declined in the first week after the procedure (mean 4 +/- 1.4; range, 1 to 7) followed by a gradual and significant (P < 0.001) decrease along the rest of the follow-up period at 4 weeks (mean 3 +/- 1.1; range, 1 to 5), 24 weeks (mean 2.2 +/- 1.1; range, 1 to 5) and 48 weeks (mean 1.6 +/- 1.1; range, 1 to 5). Eleven (58%) patients were under narcotic analgesia before sacroplasty, whereas 8 (42%) patients were using non-narcotics. Corresponding values after the procedure were 2/19 (10%; narcotic, one of them was on reserve) and 10/19 (53%; non-narcotic). The remaining 7 (37%) patients did not address post-procedure analgesic use. The evolution of post-interventional mobility was favourable in the study group as they revealed a significant improvement in their mobility point scale (P < 0.001). Long-axis percutaneous sacroplasty is a suitable, minimally invasive treatment option for patients who present with sacral insufficiency fractures. More studies with larger patient numbers are needed to explore any unrecognised limitations of this therapeutic approach.
