[Elevation of atrial natriuretic factor in alveolo-interstitial lesions of connective tissue diseases].

Plasma levels of the atrial natriuretic factor were prospectively measured in 15 patients suffering from connective tissue disease with alveolar-interstitial lung lesions. The mean level was significantly higher in these patients than in 12 patients without known lung lesions (74.8 +/- 20.7 pg/ml versus 30.8 +/- 12 pg/ml; P less than 0.01) and in 18 healthy subjects (25.4 +/- 12.6 pg/ml). There was no correlation between these levels and lung function tests. Three patients with isolated lymphocytosis in the alveolar lavage fluid had a high level of atrial natriuretic factor.

[Metacarpal bone chondrosarcoma. Apropos of a case].

On the basis of a personal case of non-symptomatic chondrosarcoma of the metacarpal bone and a review of the literature, the authors advise the biopsy of any lesion which resembles a chondroma of the hand. Only histological examination can provide evidence for diagnosis and guide effective treatment.

[Exploration of the parathyroid gland function by intake or oral calcium and phosphate (only oral intake and sequential treatment with calcium-phosphate)].

The parathyroid hormone response to the oral intake of either calcium or phosphate was explored in 10 young adults (23-28 years). First, the subjects were investigated during free running diet. They ingested a single oral dose of 500 mg of calcium (as a bag of Sandocal) and 10 days later a single oral dose of phosphate (750 mg of phosphorus as a tablet of Phosphore Sandoz Forte). Samples of blood and urine were collected before and during the 4 hours following the ingestion of either calcium or phosphate. After intake of calcium an acute response was obtained with a 58% decrease in PTH 1-84 at 1 hr (p less than 0.001) and a 33% decrease in nephrogenous cAMP (p less than 0.001). After ingestion of phosphate the response was delayed and less constant with a 25% increase in PTH 1-84 at 3 hr (p less than 0.01) and a 27% increase in nephrogenous cAMP (p less than 0.001). Then, the effects of a calcium therapy (3 daily doses of 500 mg each for 20 days) and of a subsequent phosphate therapy (2 daily doses of 750 mg each for 10 days) on the parathyroid hormone response to the administration of a single dose of phosphate were studied. On days 10, 21 and 31 baseline blood and urine samples were obtained prior to calcium and phosphate administration for measuring PTH 1-84 and nephrogenous cAMP. No significant variation was found. On days 21 (after calcium therapy) and 31 (after phosphate therapy) an oral load of phosphate was administered according to the procedure described above.(ABSTRACT TRUNCATED AT 250 WORDS)

[Primary hyperparathyroidism: value of "intact parathormone" assay (PTH 1-84)].

In a prospective study of 20 patients with primary hyperparathyroidism the diagnostic value of the intact parathormone assay was compared with that of intermediate fragment measurement and that of nephrogenic cyclic AMP determination. In the basal state, measuring the intact parathormone is the best way of separating hyperparathyroid patients form normal subjects. During calcium infusion tests, there is good concordance between changes in intact parathormone and in nephrogenic cyclic AMP. In addition, the intact parathormone assay enables a thorough study of the relationship between ionized calcaemia and parathyroid secretion to be performed and confirms the existence, in hyperparathyroid patients, of two types of secretory response to a rise in calcaemia. Being more reliable than the measurement of a C-terminal or intermediate fragment and easier to perform than nephrogenic cyclic AMP determination, the intact parathormone assay seems to be particularly suitable for the study of primary hyperparathyroidism.

[Expression of pain in rheumatic disease. Exploratory study].

An investigation done in 34 rheumatology departments on 259 patients in order to analyse their perception of pain and its repercussions on daily living. The main three diseases justifying hospitalization are: rheumatoid arthritis, lumbosciatica and bone neoplasia. In these patients, pain occurs daily in 75 p. cent of them and continuous in 32 p. cent; the intensity of the pain varies according to the time. There are repercussions on work (63 p. cent), walking (81 p. cent), but also on leisure (74 p. cent), friendly interelations (42 p. cent) and disposition which is disturbed in 62 p. cent of patients. Behavioral analysis in the presence of pain brings up differences depending on the patients: the elder the patient, the least they are able to respond to the handicap caused by pain. Analysis of the pain vocabulary suggest that if the terms expressing the experience of the patient are different according to the diseases, the usual description of painful phenomena are common to patients and the diseases in question.

Erosive arthritis of the costovertebral joint in seronegative spondyloarthropathy.

A 50-year-old male presented with polyarthritis and pain of the right costovertebral angle in the cervicothoracic area. Radiological findings in a sacroiliac joint, the presence of a syndesmophyte, the HLA B-27 phenotype and negative serological studies prompted the diagnosis of HLA-B27 related seronegative spondyloarthropathy. Conventional and computerized tomograms disclosed an erosive arthritis of the 1st right costovertebral joint that was responsible for the pain in the costovertebral angle. We are unaware of previous CT scan documentation of such lesions.
