Heterotopic ossification and rhabdomyolysis.

Heterotopic ossification and rhabdomyolysis are well described entities but, as far as we know, their association has never been described in the literature. We recently treated a patient who presented with this association. After a suicide attempt, this patient developed rhabdomyolysis of the left upper and lower limbs with peripheral neurological impairment. Two months later radiographs showed ectopic ossification around the left hip. Rhabdomyolysis is underdiagnosed, and is due to local disturbance of the calcium-phosphorus metabolism resulting in soft tissue calcifications. Underlying rhabdomyolysis may be a possible aetiology of heterotopic ossification. Recognition of this may help us to understand the pathophysiology and to improve the management of heterotopic ossification.

[Functional ability and quality of life in rheumatoid arthritis: use of the Functional Independence Measure and the Reintegration to Normal Living Index]. / Capacité fonctionnelle et qualité de vie dans la polyarthrite rhumatoïde: utilisation de la mesure de l'indépendance fonctionnelle (MIF) et de l'index de réintégration a la vie normale (RNLI).

Functional disability and quality of life were evaluated using the Functional Independence Measure and the Reintegration to Normal Living Index, respectively, in 57 subjects (15 men and 42 women) with a mean disease duration of 15 years. Scores on both these nonspecific scales correlated with those obtained using instruments specifically designed for rheumatoid arthritis (ARA index, Lee index) and with a number of clinical parameters including patient age, disease duration and number of affected joints. Functional ability was correlated with quality of life in this study and in others performed using other evaluation tools. Nonspecific assessment scales are useful for comparing function and quality of life in various diseases.

A comparative study of the muscle strength and mass of the arm flexors and extensors in paraplegic and in non paraplegic basketball players.

OBJECTIVES: to study the changes in the strength of the elbow flexors and extensors in paraplegic subjects, and the agonist/antagonist mass and strength ratio in paraplegic wheelchair users. METHOD: 10 paraplegic wheelchair basketball players were compared with 10 healthy basketball players. The 20 subjects underwent a clinical and dynamometric isokinetic assessment, and a CT scan measurement of the muscle cross-sectional surface area of the flexor and extensor muscles of the elbows. RESULTS: there was an increase in muscle strength in paraplegic subjects. There was no significant difference in the agonist/antagonist ratio between the dominant and non dominant upper limb in paraplegics whereas such a difference was found in healthy subjects. The muscle mass was increased in the paraplegics, but a correlation between muscle mass and strength was only found in the healthy subjects.

Posturographic evaluation of the proprioceptive effect of ankle orthoses in healthy volunteers.

This study analyses the proprioceptive effect of wearing a unilateral and then bilateral ankle orthosis on 34 healthy volunteer subjects by posturography. An elastic orthosis with a ligamentous support band was used, and evaluation was performed by a posturographic statokinesimetric platform. Three tests, one without an orthosis, one with one orthosis, and one with two orthoses, were recorded for each volunteer. The results and statistical analyses demonstrated a significant difference in the antero-posterior measurement between the test without ankle orthosis and the tests with one and with two orthoses. This study provides information about the prophylactic effect of wearing a flexible support; it appears that there are important inter-individual variations in postural equilibrium, and the wearing of prophylactic ankle orthoses should be reserved for subjects after a posturographic examination.

Radionuclide bone imaging in diaphyseal aclasis with malignant change.

Chondrosarcoma is a rare complication in hereditary multiple exostoses. The six patients in this study have had a complete follow-up and constitute the largest group of such cases to have been studied so far. Five patients had histologic evidence of malignancy. Since histologic examination can be very difficult, any other diagnostic features, may it be clinical, radiologic, or scintigraphical, should be taken into account for early surgical treatment. Bone scintigraphic examination is a valuable adjunct to early diagnosis of malignant change by showing highest uptake in malignant areas. It is also very useful for posttherapeutic follow-up.

[Critical study of the interpretation and use of laboratory biochemical examinations in a hospital milieu]. / Essai d'étude critique de l'obtention et de l'utilisation des résultats d'examens de laboratoire de biochimie en milieu hospitalier.

The criticism of interpretation of routine biochemical examinations by four clinical units (motor rehabilitation, cardiology, gastro-enterology, diabetes) was in relation to four criteria: result in agreement with the clinical observation but not providing new information, result in disagreement with the clinical observation and judged too low, result in disagreement with the clinical observation and judged too high. The comparison of judgements with regard to various analysis permits one to discuss applications of a method of objective assessment of the dialogue between the laboratory and the clinical units.
