[Improvement of pneumococcal immunization coverage in older patients]. / Amélioration de la couverture vaccinale anti-pneumococcique chez le sujet âgé.

PURPOSE: To study pneumococcal immunization coverage in older patients in hospital, and the impact of two actions aiming at improving this coverage. METHODS: We reported a prospective and descriptive study conducted from November 2009 to August 2010, including all new patients ≥75 years old received in a geriatric short-stay department and residing in Val-de-Marne, France. This study was performed in three successive three-month periods, to assess the vaccination coverage in the months following hospital release. Period I was the reference; Period II included an awareness campaign of general practitioners relying on the hospitalization discharge report, containing an indication for the vaccination; Period III consisted in a systematic proposal of vaccination by the geriatric hospital department. RESULTS: Indication for pneumococcal vaccination has been given to 139 patients (61.2%) in 227 processed questionnaires. The main indication was heart failure for 105 patients (75.5%). Twenty-four patients were already vaccinated (17.2%). No vaccination was reported in the three months following period I in 33 included patients. The awareness campaign targeting regular doctors resulted in only one vaccination out of 37 patients. Immunization coverage in the department had reached 84.5% of inoculation (38 of 45 patients). CONCLUSION: Pneumococcal vaccination is often prescribed in elderly patients but generally not executed. The awareness campaign did not result in a big enough immunization coverage improvement, compared to a codified proposal of vaccination during hospital stay.

The role of androgens or growth factors in the bone resorption process in recent spinal cord injured patients: a cross-sectional study.

STUDY DESIGN: This cross-sectional study compared the androgen and growth factor profiles and the bone turnover of patients with spinal cord injury (SCI) versus able-bodied controls (AB). OBJECTIVE: Determine whether androgens, GH, or either IGF-I or IGFBP-3, are implicated in bone turnover alteration in patients with recent SCI. SETTING: Propara Center, Montpellier, France. METHODS: In all, 16 men (31.3 years) with complete SCI, seven paraplegics and nine tetraplegics, who had sustained injury an average of 3 months earlier, and 12 AB who served as controls (27.5 years) participated. Androgens, growth hormone and its mediators were investigated. The bone resorption process was evaluated by urinary and plasma type I collagen C-telopeptide (CTXu, CTXp), while bone formation was evaluated by osteocalcin (OC) and bone alkaline phosphatase. RESULTS: Total testosterone (TT) and the free androgen index (FAI) were significantly lower in the SCI patients, whereas FSH was significantly higher (P<0.05). These hormonal variations were not related to the level of neurological lesion. There was no significant difference in GH, IGF-I, or IGFBP-3 levels. CTXu and CTXp indicated high bone resorption activity in the SCI patients (P<0.05). Regarding bone formation markers, only OC was affected by neurological lesion (P<0.05). Basal hormone levels did not correlate with markers of bone turnover. CONCLUSION: The high bone resorption process observed in SCI patients did not seem directly related to testicular endocrine abnormalities or an altered growth factor profile. Nevertheless, the reduced TT and FAI levels could be aggravating factors in the development of acute bone loss.

Changes in osteoprotegerin/RANKL system, bone mineral density, and bone biochemicals markers in patients with recent spinal cord injury.

This study analyzed the temporal and regional variations in bone loss and explored bone cell activities via biochemical markers during an extended follow-up in patients with spinal cord injury (SCI). In parallel, the possible role of the osteoprotegerin (OPG)/RANKL system in disuse osteoporosis was investigated. Seven male patients with acute and complete SCI (31.3 +/- 9.5 years) and 12 able-bodied (AB) men (26.9 +/- 4.2 years) participated in the study. Measurements were performed 16, 24, 36, 48, and 71 weeks after injury. At week 16, marked calcium homeostasis disturbance and a concomitant increase in bone resorption markers were observed, reflecting an intense bone degradation process. Resorption activity decreased continuously with time. Contrasting with the great rise in the resorption markers, the bone formation markers showed little variation. During the period of investigation, a loss in bone mineral density (BMD) was demonstrated for the total body (-4.3%), pelvis (-15.7%) and lower limbs (-15.2%), whereas BMD did not change at the lumbar spine, upper limbs, or skull. At all stages, SCI patients had lower serum RANKL levels and higher serum OPG levels than did AB controls, but no significant variation with time was observed for either cytokine. These findings suggest that bone resorption persisted long after SCI and specifically affected BMD at sublesional sites. The marked modification of serum OPG/RANKL levels in SCI patients suggests that this system is affected, in disuse osteoporosis. However, the precise biologic role of the OPG/RANKL system in the bone tissue of SCI patients has yet to be determined.

Effects of physical activities that induce moderate external loading on bone metabolism in male athletes.

Sports characterized by little or moderate weight bearing or impact have a low osteogenic effect. However, the action of such sports on bone turnover remains unclear. The objective of this study was to determine the effect on bone remodelling of physical activities that induce moderate external loading on the skeleton. Thirty-eight male athletes aged 18-39 years (cyclists, n = 11; swimmers, n = 13; triathletes, n = 14) and 10 age-matched sedentary controls aged 22-35 years participated in the study. The study combined measurement of bone mineral density by dual-energy X-ray absorptiometry and bone turnover assessment from specific biochemical markers: serum bone-specific alkaline phosphatase, osteocalcin, urinary type I collagen C-telopeptide and calcium. Compared with the controls and swimmers, adjusted bone mineral density was higher (P < 0.05) in triathletes at the total proximal femur and lower limbs. No differences in bone mineral density were found between cyclists, swimmers and controls. Compared with controls, osteocalcin was higher (P < 0.05) in triathletes and swimmers and urinary type I collagen C-telopeptide was higher in swimmers only. Serum bone-specific alkaline phosphatase was lower (P < 0.05) in cyclists than in all other groups. In conclusion, an osteogenic effect was found only in triathletes, mainly at bone sites under high mechanical stress. Bone turnover differed in athletes compared with controls, suggesting that bone turnover may be sport-practice dependent. Despite some encouraging observations, it was not possible to show that changes in the bone remodelling process were sport-discipline dependent.

[Resurgence of syphilis: a prospective study at an University Hospital, Nimes]. / Recrudescence de la syphilis: à propos d'une étude prospective au CHU de Nîmes.

BACKGROUND: Since 2000, the incidence of syphilis has increased in France. The study objective was to estimate the frequency of syphilis in Languedoc Roussillon region in Southern France. METHOD: The prospective study was conducted between January 1, 2003 and June 30, 2003 in different medical wards in a French University Hospital, Nimes. The diseased patients in this study answered to a questionnaire, providing epidemiological and socio-economic data, symptomatology and treatment-seeking behaviour. Blood specimens were tested for syphilis by the serological methods (TPHA, VDRL, FTA). RESULTS: In 6 months, serologic evidence of syphilis infection was found in 30 patients. Men were more than twice as likely as women to be infected with syphilis. Most men (64.7%) acquired the infection homosexually. Four women acquired infection during pregnancy. The mean age of study population was 46.3 years. 40.7% were married. Out of 27 cases, 70.4% cases had an associated sexually transmitted infection (HIV, hepatitis, herpes, and gonorrhoea). CONCLUSIONS: These data confirm the increase of syphilis in south of France and underline the importance of a permanent monitoring of sexually transmitted infection in target populations to allow a timely diagnosis and an appropriate treatment, and to plan preventive strategies.

Testosterone is significantly reduced in endurance athletes without impact on bone mineral density.

AIMS: To compare the basal plasma reproductive hormonal profile in three groups of athletes involved in different training programs, and to define the relationship between androgen level and bone mineral density (BMD) in male athletes. METHODS: Basal serum total testosterone (TT), free androgen index (FAI), sex hormone-binding globulin (SHBG), cortisol, cortisol to TT ratio, luteinizing hormone (LH), estrogen and BMD were evaluated in cyclists (CY; n = 11), triathletes (TR; n = 14) and swimmers (SW; n = 13) and compared with less active controls (n = 10). RESULTS: TT and FAI levels were lower (p < 0.05) in CY and TR, whereas the ratio of cortisol to TT was increased in CY only (p < 0.05). No alteration in serum LH, SHBG, estrogen or cortisol concentration was observed. BMD was higher in the proximal femur in TR (p < 0.05). No BMD or hormonal differences were found in SW. CONCLUSION: Only the endurance training of CY and TR induced androgen deficiency without apparent alteration of BMD.

Celecoxib is as efficacious as naproxen in the management of acute shoulder pain.

This study compared the analgesic efficacy and safety of the cyclo-oxygenase-2 specific inhibitor celecoxib with the non-specific non-steroidal anti-inflammatory drug, naproxen, in patients with acute shoulder pain. Adult patients with shoulder pain, onset within the previous 14 days and shoulder pain of > or = 40 mm on a 100 mm visual analogue scale (VAS), were treated with oral doses of celecoxib or naproxen for 14 days and followed by a visit at day 42 in a double-blind, randomized study. The primary efficacy assessment was change in maximum pain at rest on a 100 mm VAS at day 14 compared with baseline. In addition, secondary efficacy pain and functional assessments were analysed at baseline, day 14 and day 42. A total of 202 patients were included in the trial (99 celecoxib 400 mg/day; 103 naproxen 1 g/day). The difference in change from baseline at day 14 in maximum pain at rest was not statistically significant between the two treatment groups, but was numerically higher for celecoxib than for naproxen (-47.9 +/- 2.5 versus -42.3 +/- 2.5, respectively). According to the limits of the 95% confidence interval of the difference between groups (-12.52; 1.38), celecoxib appeared to be at least as effective as naproxen. All secondary efficacy measures followed the same pattern, showing similarity between the two treatments with a trend in favour of celecoxib. The incidences of adverse events were similar for both groups. Fewer patients experienced epigastric pain with celecoxib (seven patients versus 14 with naproxen). This adverse event led to discontinuation in two patients receiving celecoxib and five receiving naproxen. Celecoxib 400 mg/day was at least as effective as naproxen 1 g/day in managing pain in this condition.

[Anatomy, physiology and clinical examination of the shoulder]. / Anatomie, physiologie et examen clinique de l'épaule.

Shoulder pain is usually caused by periarthritis. Impingement syndrome and frozen shoulder (adhesive capsulitis) are the more frequently clinical aspect observed. A shoulder standardised clinical examination often give a precise lesional diagnostic. Complementary examinations are useful to distinguish other cause of shoulder pain.

Neurological complications in insufficiency fractures of the sacrum. Three case-reports.

Three cases of nerve root compromise in elderly women with insufficiency fractures of the sacrum are reported. Neurological compromise is generally felt to be exceedingly rare in this setting. A review of 493 cases of sacral insufficiency fractures reported in the literature suggested an incidence of about 2%. The true incidence is probably higher since many case-reports provided only scant information on symptoms; furthermore, sphincter dysfunction and lower limb paresthesia were the most common symptoms and can readily be overlooked or misinterpreted in elderly patients with multiple health problems. The neurological manifestations were delayed in some cases. A full recovery was the rule. The characteristics of the sacral fracture were not consistently related with the risk of neurological compromise. In most cases there was no displacement and in many the foramina were not involved. The pathophysiology of the neurological manifestations remains unclear. We suggest that patients with sacral insufficiency fractures should be carefully monitored for neurological manifestations.

Tophaceous gout of the navicular bone as a cause of medial inflammatory tumor of the foot.

A case of tophaceous gout of the navicular bone in a 24-year-old woman is reported. Emphasis is placed on the conditions that might have been precipitating, i.e., anorexia nervosa and alcoholism, and the mechanisms by which increased uric acid level may be explained. The main radiographic patterns of tophaceous gout of the foot are recalled to avoid unnecessary surgery in future cases.

Postoperative shoulder rotators strength in stages II and III impingement syndrome.

In healthy subjects, the shoulder internal rotator muscle strength overrides the external rotators. This has been confirmed in different isokinetic studies showing the ratio of the relative strengths of the internal to external rotators to range from 1.3 to 1.5 points, depending on the study. The authors previously reported a decrease in the relative strength ratio of the internal to external rotators to close to 1 in patients suffering from Neer's impingement syndrome. The aim of the present study was to assess, long after surgery (mean, 44.5 months), the isokinetic strength performance of shoulder rotator muscles in 72 patients who had had operative treatment for chronic subacromial impingement using anterior acromioplasty, sometimes combined with cuff repair surgery. Tests were conducted with a Biodex Multi-Joint System in the plane of the scapula and in 45 degrees abduction at 60 degrees and 180 degrees per second. Peak torque and average power were calculated. The mean ratios of relative strengths of the internal to external rotators ranged from 1.3 to 1.6 points depending on the parameter studied and the test speed. These results indicate that surgery restores normal muscular balance between shoulder rotator muscles affected by the impingement syndrome.

Diagnostic value of clinical tests for shoulder impingement syndrome.

Results of three clinical tests for detecting shoulder impingement syndrome (Neer's, Hawkins', and Yocum's tests) and four tests for determining the location of the rotator cuff lesion (Jobe's test [supraspinatus], Patte's test [infraspinatus], lift-off test [subscapularis], and palm-up test [long head of the biceps brachii]) were compared to intraoperatively observed anatomic lesions in 55 consecutive patients who had surgery for Neer's syndrome. For Jobe's and Patte's tests, both pain (denoting tendinitis) and functional impairment (denoting tendon rupture) were evaluated. All clinical tests were done by the same examiner and all surgical procedures (acromioplasty with or without rotator cuff repair) by the same surgeon. The location and extent of the lesions (size of the tear in the 34 patients with rotator cuff defects) were determined intraoperatively. The sensitivity, specificity, and positive and negative predictive values of each test were calculated. Sensitivity was satisfactory but specificity was poor, in particular for determining the location and type of rotator cuff lesions. The severity of functional impairment during Jobe's and Patte's maneuvers was not correlated with the size of the tear.

Conversion of endogenous arachidonic acid to 5,15-diHETE and lipoxins by polymorphonuclear cells from patients with rheumatoid arthritis.

The conversion of endogenous arachidonic acid (AA) by polymorphonuclear cells (PMN) from patients with rheumatoid arthritis (RA) was studied before (D0) and one day (D1) after antiinflammatory drug therapy. The biosynthesis of 5,15-diHETE and lipoxins (LXS), were investigated ex vivo, after PMN stimulation by ionophore A23187 without exogenous addition of 15-HETE. The eicosanoids were resolved by RP-HPLC and simultaneously detected at 246 and 302 nm respectively. Large amounts of 5,15-diHETE (50 to 400 ng/10(7) PMN) and significant levels of LXS (from 2 to 20 ng/10(7) PMN) were produced with individual differences between donors. Metabolite levels varied between patients but this work showed for the first time a linear relationship between the amounts of 5,15-diHETE and LXS. Moreover LXS production after treatment may be related to long-term clinical improvement of patients.

Tophaceous gout of the patella with primary hyperparathyroidism.

The case of an 81-year-old woman with persistent post-traumatic pain of the knee linked to tophaceous gout of the patella is presented. This gout was associated with adenomatous primary hyperparathyroidism. The relationship between hyperuricemia, hyperparathyroidism and chronic renal failure is discussed.

Multiple psoas abscesses after posterior spinal fusion.

STUDY DESIGN: A case of multiple psoas abscesses after Dove lumbar spine fixation is reported. OBJECTIVES: To review the diagnosis and treatment of deep infection after internal spinal fixation. METHODS: The possibility of septic complications after spinal surgery that may present with a degenerative pattern is examined. The clinical and computed tomographic findings of a psoas abscess are recalled. RESULTS: Surgical drainage of the purulent collection was performed along with prolonged parenteral antibiotic treatment. CONCLUSION: Infection should be considered as a cause of recurrence of pain after internal fixation of the lumbar spine.

Enhancement of leukotriene A4 biosynthesis in neutrophils from patients with rheumatoid arthritis after a single glucocorticoid dose.

Human blood polymorphonuclear cells (PMN) from seven patients with active rheumatoid arthritis (RA) were compared for their capacities to produce leukotrienes ex vivo before (D0) and 24 hr (D1) after glucocorticoid pulse therapy. The present study shows for the first time that endogenous arachidonic acid metabolism via 5-lipoxygenase pathway is significantly increased after glucocorticoid administration, leading to increased generation of the unstable precursor leukotriene A4 (LTA4) followed by predominant non-enzymatic LTA4 opening and leukotriene B4 (LTB4) omega-hydroxylation pathway. These results are unexpected since usually glucocorticoids are usually thought to decrease inflammatory mediator biosynthesis and, moreover, they work to the detriment of the clinical improvement of the patient. The results are discussed in terms of product inactivation and cellular cooperation with monocytes and endothelial cells.

Primary Subcutaneous Abscess and Osteitis Caused by Nocardia asteroides.

We describe the case of a 84-year-old man with a subcutaneous abscess and osteitis of the lower limb caused by Nocardia asteroides. Attention is drawn to the infrequency of Nocardia asteroides cutaneous infection without previous pulmonary involvement. Moreover, sulfonamides were surprisingly not effective in this case, but pefloxacin was.

Isokinetic evaluation of rotational strength in normal shoulders and shoulders with impingement syndrome.

The purpose of this study was to determine whether imbalance of the internal and external rotator musculature of the shoulder were etiological factors implicated in impingement syndrome. Shoulder torque measurements were obtained from 15 asymptomatic volunteers and 30 patients with chronic impingement syndrome, 15 of whom were evaluated after arthroscopic anterior acromioplasty. Isokinetic strength was assessed using the Biodex system in a modified position (in the plane of the scapula and in 45 degrees abduction) with test speeds of 60 degrees and 180 degrees per second. Internal and external rotator strength values and ratios were calculated for both peak torque and average power. Shoulder rotational strength values and the internal rotator/external rotator ratio were significantly higher in the dominant and nondominant control group shoulders than in the involved and uninvolved impingement shoulders for operated on and nonoperated on patients. These data demonstrate that primary change in the normal internal rotator/external rotator ratio of the shoulder is an etiological factor implicated in impingement syndrome not modified by anterior acromioplasty.
