[Periarteritis nodosa with heart valve disease disclosed by occlusion of the central artery of the retina].

We report a case of periarteritis nodosa revealed by blindness due to occlusion of the central retinal artery. The disease appeared after a serous otitis and was accompanied by thrombocytosis. Its outcome was favourable under corticosteroid therapy, but it was complicated by aortic valve regurgitation. Lesions of fibrinoid necrosis were found on the aortic cusps removed during surgical replacement. It seems highly probable that the ocular and valvular lesions were specific, although this cannot be directly demonstrated. The case presented here is exceptional, and the relevant literature is reviewed.

[Treatment with iloprost of critical ischemia of the lower limbs associated with cardiac insufficiency. Study of interaction with the pharmacokinetics of digoxin].

We have treated with intravenous iloprost twelve patients suffering from cardiac insufficiency compensated under oral digoxin (NYHA class II) associated with severe limb ischaemia due to arterial insufficiency. Our aim was to study its possible interaction on digoxin levels and to evaluate the long-term efficacy of iloprost. Although iloprost slowed the digoxin absorption by approximately one hour, we found no clinically significant difference between the digoxin pharmacokinetic data before and during treatment by iloprost. Moreover, 11 out of the 12 patients had a good clinical fate after the treatment, which persisted at 6 months. The pain disappeared in 4 and diminished in 7; and all skin ulcers healed. This improvement has lasted up to two and a half years in two patients. The clinical tolerance of iloprost was acceptable despite frequent headache and flushing associated with hypotension and nausea. We conclude that iloprost seems to be a very promising treatment of severe limb ischaemia when no intervention on the proximal arteries is possible. The patients on digoxin can continue their treatment without dose alteration while starting on iloprost.

[Paralytic shellfish poisoning (author's transl)].

Different diseases as viral or bacterian gastro-enteritis, Tiphoid, viral hepatitis can come from shellfishes. Less known is the shellfish poisoning although recent outbreaks took place in Spain, France, England, Morocco. Toxic poisoning is caused by a poison produced by dinoflagelates of plankton which get developped in shells and make them dangerous, even cooked, to be eaten. A respiratory failure can result from this neurotropic poison.

Two familial cases of malignant Reiter's syndrome.

A Cambodian man and his son concomitantly developed malignant Reiter's syndrome soon after their arrival in France. In both cases generalized skin lesions of pustular psoriasis and systemic features were present. The son died after 2 years of unresponsive continuously progressive disease. The father received pulses of high dose immunosuppressants that worked rapidly and prevented a life threatening course. These 2 cases illustrate the pathophysiologic hypothesis of Reiter's syndrome, emphasizing the role of environmental triggering factors and the relationship between spondylarthropathies in B27 positive patients. Fatal cases of Reiter's syndrome are very rare in the review of the literature.
