Paget's disease of the skull is the main cause of basilar artery syndromes in the adult. They may cause various neurological symptoms, including signs of ischemia of the spinal cord or medulla, or involvement of the cranial nerves and brain stem and, also, distant symptoms due to hydrocephalus, with various mental disorders including transient, recurrent, coma. The authors discuss 30 cases found in the world literature and 6 unreported personal cases, study the clinical symptoms of these cases of basilar artery compression due to Paget's disease, and the methods of neuro-radiological investigation, and emphasize the interest, in severe forms, of early surgical decompression before the stage of severe neurological complications. Regular supervision of patients with Pagets disease is thus essential to detect at an early stage, decompensation of basilar artery insufficiency in Paget's disease. In late forms, calcitonin may be indicated.

The authors report 3 new cases of femoral nerve paralysis complicating anticoagulant treatment. The first sign was pain, the neurological signs occurred later and the patient usually recovered but recovery was sometimes incomplete. The pathogenesis is not clear : a muscle hematoma, ischemia of the nerve trunk, and intraneural hemorrhage are the commonest theories.

The authors report 15 cases collected over a few years on a gastroenterology unit, and emphasize the digestive complications occurring after pelvic or abdomino-pelvic irradiation for genital carcinoma. The rectum and pelvic colon are generally affected. The delays of onset after radiotherapy may reach or exceed several months. The vascular lesions, caused by ionising radiation, explain the tissue ischemia and, consequently the failure of local medical treatment. When severe hemorrhage or visceral perforation occur, surgery is necessary. However, sutures often break down on these insufficiently vascularised tissues and re-operation is always associated with a poor prognosis.

The authors report 7 new cases of colitis above a carcinoma. The study of these cases and of those reported in the literature shows the main pathological characteristics of the lesions and permits discussion of the pathogenesis. Chronic ischemia caused by an increase in intraluminal pressure above the neoplastic stenosis seems to be the main etiological factor.

A patient with a toxic adenoma, already reduced in size by TSH, presented on the third day after treatment of a common cold by phenylpropanolomine, a severe pain in the thyroid gland. 4 weeks later, the nodule, which measured 3 x 4 cm. had clinically disappeared and the scan returned to normal. The disappearance 5 months later of the antithyroid antibodies confirmed the cure. Catecholamines, stimulating the production of thyroid hormone and producing temporary ischemia of the gland, phenylpropanolamine, a sympathomimetic drug, may have caused hemorrhagic necrosis of the adenoma and its disappearance.

The authors report a case of temporal arteritis accompanied with appearance of "cold areas" on the liver scan, regressing after steroid therapy. This observation confirms the existence of hepatic manifestation in giant cell arteritis and evokes a discussion of their mechanism. A hypothesis of hepatic ischemia is proposed.

74 by-passes on leg arteries have been performed during these last ten years at St Joseph's hospital to cure: femoropopliteal atherosclerotic occlusive disease (67 cases), aneurisms (5 cases), post-traumatic arteriovenous fistula (1 case), popliteal thrombosis on exostosis (1 case). The indication for operation was, in almost every case, carried on a distal advanced ischemia, followed by an imminent limb loss. In four cases, there existed an acute sensory and motor ischemia. The accumulated potency rate was 58.5% at 1 year and decreased progressively afterwards: 38.20% at 3 years and 21.6% at 5 years. However, the choice of a surgical technics doesn't find its justification in a long-dated prognosis for this operation, the aim of which being limb-salvage. In this prospect, the results are hopeful: 77% of the limbs have effectively been preserved at the end of the follow-up period.

During 2588 coronarography examinations conducted over a period of 4 years, assisted circulation was employed in 63 cases to reduce the risks of the examination procedure in particularly debilitated patients. These high risk cases included 48 patients with unstable angina resistant to medical treatment and 45 cases of recent infarcts with complications. Mortality with assisted circulation was very low, in spite of the severe nature of the affections, but the authors use this technique in only a limited number of cases, mainly because of the risk of lower limb ischemia, and the possibility of using intravenous nitroglycerin and analgesia from neuroleptics for examination. For this reason the number of cases examined in this way has dropped from 4% in 1977 to 2% in 1978, though assisted circulation is still employed in certain particularly severe cases of angina, and for infarcts with complications.

The effect of the reperfusion on the pathological appearance of experimental myocardial infarction has been studied in the rat (87 animals). Following permanent ischemia (33 animals sacrified after 1, 6, 24 and 48 hours), there appeared a reproducible extended transversal infarction marked by an uniform sequence of histologic, histoenzymatic and ultrastructural changes. Following temporary ischemia (54 animals), the pathological patterns were marked by myofibrillar degeneration (contraction band necrosis), cellular edema, calcium deposits and interstitial hemorrhages. These changes appeared after reperfusion of short duration (10 minutes). Sarcolemmal and capillary permeability alterations could be the main factor involved in the reperfusion injury. Similar tissue damage have been found in clinical conditions in subendocardial hemorrhagic necrosis after cardiopulmonary by-pass, and in reperfused infarction.

The authors report 31 cases of "vascular epilepsy" among 280 cerebral strokes confirmed by cranial computerized tomography. A high incidence of ischemia (28 cases : 90%) is noted. Epileptic seizures are initial (14 cases) or sequellar (17 cases) manifestations of cerebral stroke. Partial seizures are the most frequent (58%), particularly "Jacksonian" motor fits, which, when initial, often lead to status epilepticus. Frequency and bad prognosis of initial status epilepticus are pointed out.
