[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.

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.

Pubic post-fracture osteolysis simulating a malignancy.

The authors report one case of pubic post-fracture osteolysis, an uncommon and as yet not well understood pathology. It corresponds to an unusual healing of an insufficiency fracture in osteoporotic patients. Its pathogenesis is unclear, but the biomechanical theory seems to be the most convincing.

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.

Measurement of the bone mineral density of the os calcis as an indication of vertebral fracture in women with lumbar osteoarthritis.

In women with lumbar osteoarthritis, measurement of the os calcis bone mineral density (BMD) using dual-energy X-ray absorptiometry (DEXA) as an indication of vertebral fracture was evaluated. The in vivo precision of the method was 1.28%. Age- and sex-matched control curves were evaluated using a control of 193 females. The correlation between spine BMD and os calcis BMD was significant (r = 0.65, p << 0.001). For the osteoporotic women without osteoarthritis (n = 34), there was no significant difference in the spine and the os calcis Z-scores (-1.99SD and -1.83SD respectively). Whereas for osteoporotic women with osteoarthritis (n = 30) the spine Z-score was -0.49SD the os calcis Z-score was -1.92SD. The difference was significant (p < 0.001). Receiver operating characteristic (ROC) curves demonstrate the superiority of the os calcis as a measurement site over the lumbar spine, in correlation with existing crush fractures in the presence of osteoarthritis. It is concluded that when lumbar osteoarthritis occurs measurement of the os calcis BMD using DEXA is clinically useful for the estimation of bone mass.

Sacral insufficiency fractures presenting as acute low-back pain. Biomechanical aspects.

Sacral insufficiency fractures are an often unsuspected cause of low-back pain in elderly women with osteopenia who have sustained unknown or only minimal trauma. The authors describe 10 cases of spontaneous sacral insufficiency fractures, confirmed by computed tomography, characterized by the onset of acute low-back pain. Differential clinical and radiographic diagnosis of these fractures is often difficult. Recognition of the characteristic scintigraphic patterns in sacral fractures, which are frequent in osteopenic patients, could avoid mistaken diagnoses and unnecessary tests or treatment. One of the striking feature of these sacral fractures is their invariable location. The fractures extend vertically in the sacral alae, parallel to the sacroiliac joints. They are located just lateral to the margins of the lumbar spine. This distribution suggests that such fractures could be partially caused by weight-bearing transmitted through the spine.

Lumbar posterior marginal node (LPMN) in adults. Report of fifteen cases.

This report concerns 15 adults (nine men and six women) who experienced lumbar and sciatic pain associated with an unusual defect of the edges of the vertebral bodies together with a small bony ridge protruding into the spinal canal. This lesion was well demonstrated by computed tomography and easily differentiated from the posterior longitudinal ligament or herniated disc calcifications, as well as from posterior degenerative ridge osteophytes. This lesion looked like the so-called lumbar posterior marginal node. First described in adolescents, this entity was considered as a traumatic fracture of the posterior ring apophysis. Recently, identical cases were noted in young adults in the absence of previous trauma, which were a particular type of marginal cartilaginous node. In the cases reported here, the computed tomographic scans suggested several mechanisms of formation of the vertebral lesion: a variant of marginal cartilaginous nodes; traumatic avulsion; avulsion related to disc herniation; and fusion of the avulsed bony fragment with the vertebral body.

Stenosis of the lumbar spinal canal in vertebral ankylosing hyperostosis.

Certain morphologic features frequently observed in radiography or computed tomography (CT) scan in patients with hyperostosis led us to study the association between a narrowed spinal canal and vertebral hyperostosis. Twenty-eight items were selected and studied by three different investigators (two rheumatologists and one radiologist) in radiographs and CT scans of 100 patients with acquired stenosis of the lumbar canal, with or without hyperostosis (46 and 54 cases, respectively). The most distinctive points that we suggest can be used as diagnostic criteria of the hyperostotic narrowed lumbar canal are anterior or posterior lateral marginal somatic osseous proliferations, proliferations of the nonarticular aspects of the posterior apophyses, and ossifications of the posterior articular capsule and of the ligaments (yellow ligament, posterior longitudinal ligament, and the supraspinal ligament). Four of these six criteria should be present to establish the diagnosis of hyperostotic lumbar stenosis. The appearance of lumbar hyperostosis on X-ray or CT scans differs from that of simple degenerative changes due to arthrosis, and the hyperostosis can be held responsible for dural compression.

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.

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.

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.

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.

[Meningoencephalitis disclosing Behçet disease. Value of nuclear magnetic resonance imaging]. / Méningoencéphalite révélatrice d'une maladie de Behçet. Intérêt de l'imagerie par résonance magnétique nucléaire.

A meningoencephalitis Behçet's disease revealing is reported. Magnetic resonance imaging is more sensitive than computerized tomography in detecting encephalitic lesions. However, no specific pattern may be retained. This exploration is non invasive and can be used to monitor the evolution after treatment.

[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.

[Cauda equina syndrome disclosing adenocarcinoma of the ethmoid]. / Syndrome de la queuè de cheval révélateur d'un adénocarcinome de l'ethmoïde.

Cauda equina metastases have been exceptionally described in sinusal neoplasms. MRI with gadolinium injection show up the primitive lesion and its neurologic extension. We report a case of cauda equina syndrome in which, only MRI, had show up intradural metastases and localised the ethmoïd sinus carcinoma.

[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.

[Inferior glenohumeral subluxation: an indirect sign of sepsis of the shoulder]. / Le décrochement gléno-huméral inférieur: un signe indirect de sepsis de l'épaule.

Drooping shoulder is a roentgenographic abnormality consisting in a discontinuity in the scapulo-humeral arch due to inferior subdislocation of the humeral head. Drooping shoulder is commonly seen in patients with injuries to the shoulder or neurological loss. Two cases of drooping shoulder due to staphylococcal arthritis (after local corticosteroid injections) are reported herein. The mechanism of the downward humeral displacement in septic arthritis is discussed. The other causes of drooping shoulder are reviewed. Precautions needed to avoid increasing the displacement during rehabilitation therapy are outlined.

[Determination of the instantaneous center of rotation of the shoulder using the ELITE system. Application to the study of normal and pathological abduction]. / Détermination du centre instantané de rotation de l'épaule par le système ELITE. Application à l'étude de l'abduction normale et pathologique.

The authors determined the in vivo displacement of the instantaneous center of rotation (ICR) of the shoulder from data supplied by an optoelectronic system (ELITE System) which uses a specifically designed software program to achieve 3-dimensional analysis of abduction. The study involved 10 control subjects and 20 patients suffering from a periarticular disorder of the shoulder capsule retraction in 10 cases and rotator cuff tears before and after rehabilitation in 10 cases. This method provides an objective assessment of humeral head misalignment in relation to the glenoid cavity induced by the periarticular shoulder disorder and of the realignment achieved through rehabilitation. The proposed ICR calculation technique is entirely harmless for the patient in (particular because it requires no radiation analysis).
