[Osteoporosis during pregnancy. 4 cases].

Osteoporosis of pregnancy is an infrequent condition of unclear pathogenesis. We report four new cases. Mean age of patients was 28 years; diffuse bone loss was seen on pre-pregnancy roentgenograms in two patients. Two patients were primiparas. In all four cases, acute spinal pain led to the discovery of vertebral crush fractures and diffuse osteopenia predominating in the spine and pelvis. Urinary calcium was low in one case. Our cases and a review of the literature demonstrate that diffuse osteopenia exists prior to the pregnancy and becomes symptomatic during childbearing as a result of additional mechanical stresses with or without concomitant vitamin D deficiency and/or heparin therapy.

[Inflammatory Gorham disease].

The case of a 48-year old female with massive osteolysis since the age of 13 years is reported. She had inflammatory flares which resolved spontaneously or after a transient discharge of lymph.

[Antigliadin antibodies in rheumatoid arthritis].

To investigate the potential role of gliadin in the pathophysiology of some cases of rheumatoid arthritis (RA), the authors assayed antigliadin antibodies (AGAb) in RA patients. They used an ELISA to determine AGAb levels in 100 RA patients, a group of RA-free controls with a variety of inflammatory diseases (ID), and a group of controls with noninflammatory diseases (NID). The authors found no significant increase in AGAb titers in the RA patient group as compared with either control group. Only nine patients with RA had detectable levels of AGAbs, which were of the IgG type in seven cases and of the IgA type in two cases. RA patients with and without AGAbs were compared. Patients with AGAbs more often had signs of autoimmune disease including sicca syndrome, positive tests for rheumatoid factor, and positive tests for antinuclear antibodies.

[Peripheral erosive arthritis in pustulosis palmoplantaris. Apropos of 3 cases].

Three cases of pustulosis palmoplantaris with erosive arthritis are reported. There were two females (aged 53 and 59 years) and one male (aged 39 years). Skin lesions preceded joint lesions in every case (by 2 years, several weeks, and 1 year, respectively). Joints involved were one wrist in two patients and both hips in one patient. Inflammatory joint pain occurred concomitantly with an exacerbation of the skin disease. In two cases, an upper respiratory tract infection preceded the joint manifestations by a few days. Synovial fluid from affected joints was obtained in all three cases and found to be sterile. In the two patients who had histologic studies of skin lesion biopsy specimens, unilocular non-spongiform lesions suggestive of nonpsoriasic disease were found. Erythrocyte sedimentation rate and C-reactive protein levels were raised in every case. HLA groups were [A2, A19, B12, B27], [A2, A9, B12, B19, B27, Dr4, Dr6], and [A2, A19, B12, B13, Dr7, Dr8]. All three patients were given a nonsteroidal antiinflammatory agent. Despite this therapy, destruction of the wrist occurred in both females and bilateral hip destruction required bilateral total hip replacement in the male. The rapidity with which joint destruction occurred suggested infectious disease, especially due to a saprophytic organism. Virtually all previously reported pustulosis palmoplantaris patients with bone and joint manifestations had arthralgia or non-destructive arthritis in appendicular joints, whereas bone and joint destruction has been described in axial structures.

[Systemic urticaria, sclerosing osteopathy, monoclonal gammopathy (Schnitzler syndrome). Apropos of a case].

A 65 years old man has been suffering from the upper limbs and legs for 2 years. Bone pain was associated with a non pruritic chronic urticaria and fever. Bone scintigraphy showed lesions of the lower limbs. X rays showed only one sclerotic bone lesion. Immunoelectrophoretic analysis showed an IgM kappa monoclonal gammapathy. Bone marrow aspirate and bone marrow biopsy were normal. The association of chronic urticaria, bone pain and macroglobulinemia has been first reported by L. Schnitzler. Seventeen other cases have been reported in the literature. The pathogenesis of the syndrome is unknown although anti-interleukin 1 alpha autoantibodies were found in several cases (8 out of 13).

[The influence of buprenorphine and tramadol on the postoperative CO2 response after general anaesthesia (author's transl)].

The degree of respiratory depression caused by buprenorphine and tramadol were studied in two groups of 25 patients each by means of Read's re-breathing technique. The estimations were made during the immediate postoperative stage in order to include potential residual effects of the general anaesthesia. The slope of the CO2 curve as a measure of respiratory depression decreased by 27 per cent after administration of 0.3 mg of buprenorphine, a reduction which equals that produced by potent morphine-type analgesics. The response to 50 mg of tramadol was a non-significant decrease by 3 per cent. At doses mentioned buprenorphine produced reliable pain relief, whereas with tramadol the failure rate was 28 per cent. There was no difference between the two drugs in respect of circulatory reactions and side-effects. Despite its depressing effect on the respiration (an action it shares with all potent analgesics) buprenorphine is a very useful analgesic because it provides excellent pain relief, has no or only minimal addictive properties and is not subject to the Dangerous Drugs Act.

Experimental canine atherosclerosis and its prevention. The dietary induction of severe coronary, cerebral, aortic, and iliac atherosclerosis and its prevention by safflower oil.

Severe atherosclerotic lesions were produced without thyroid suppression in seven out of eight dogs by feeding semisynthetic diets containing 5 per cent cholesterol and 16 per cent hydrogenated coconut oil for 12 to 14 months. Occlusive plaques were located in the coronary arteries and major cerebral arteries as well as in the aorta and iliac vessels. The lesions were characterized by an intense sclerotic reaction to areas of lipid deposition and foam cell accumulation in the intima. The diet induced a rapid elevation of plasma-free and esterfied cholesterol, triglyceride, and phospholipid, and the extent of aortic atherosclerosis was shown to be partially dependent on mean plasma cholesterol concentration. A second group of eight dogs were fed a diet identical with the first except for the replacement of 4 per cent hydrogenated coconut oil by 4 per cent safflower oil. Despite receiving the same amounts of dietary cholesterol and fat, this second group of dogs was completely protected from the atherogenic process. Plasma lipids became only slightly elevated and no induced atherosclerotic lesions were found at autopsy. Circulating thyroid hormone concentrations were similar between the two groups of dogs and the thyroid glands had a normal morphology in both groups.
