A total of 35 cases of periarticular new bone formation (PNBF) was observed among 160 patients with coma following severe craniocerebral trauma. All cases were associated with blunt trauma and none with penetrating wounds. Only 6 of 500 cases of acute non-traumatic hemiplegia developed PNBR, and all 6 of them followed craniotomy, brain surgery and coma. New bone formation first appeared mainly between 50 and 120 days after craniocerebral injury with prolonged coma. Three-quarters of the patients with PNBF showed involvement of the shoulder joint, but this was not associated with previous subluxation. Metabolic studies were done in some patients; no disturbances were found in the metabolism of calcium, phosphorus or alkaline phosphatase. The pathologic process of PNBF seemed to stabilize some 6 to 8 months following trauma, and surgery after this period produced functional improvement in the 3 patients in whom it was tried. No satisfactory pathophysiological explanation has been found for the phenomenon of PNBR. Prolonged coma is common to all patients who suffered from PNBF and is probably an etiologic factor. The absence of PNBF in cases of cerebrovascular accident with subluxations of the gleno-humeral joint and intensive physiotherapy seems to contradict the suggestion of microtrauma as an etiological factor.

A case of alternating hemiplegia in a young girl is presented. The partial benefits of treatment with a calcium antagonist Flunarizine in this patient and in those reported in literature are reviewed. The onset of the disease in this girl was at three months of age with several episodes that were diagnosed as seizures; afterwards she presented, besides, repeated attacks of hemiplegia involving both sides of her body in an alternating way each time with daily frequency and hours of days of duration accompanied of bad mood and irritability as well as autonomic disturbances, oculomotor abnormalities, acquired mental retardation and residual focal neurological abnormalities. After one year of treatment with a calcium-entry blocker: Flunarizine, there was a 30% reduction in the attacks frequency as well as in its severity and stop of the progression of mental retardation. So we report the consequence of precocious diagnosis and treatment of this not well known entity whose clinical signs resemble paroxistic vascular anomalies in the brainstem territory.

Twelve children with alternating hemiplegia were treated with the calcium-entry blocker flunarizine for 4 months. All but one patient responded favourably with a reduction in frequency and/or duration and severity of attacks. Interictal symptoms decreased and mental development improved in several patients. Nine of the patients entered a subsequent double-blind placebo-controlled withdrawal study lasting another 4 months. Relapses were observed in part of the placebo as well as of the flunarizine-treated patients. The reason for this is not clear, since it is unlikely that the favourable response during the initial open-label study would be due to a placebo effect, or that tolerance to the drug had developed. Feed-back from the parents rather suggests that stress and tension, which were known trigger factors in a majority of these patients, played a role when the patient was switched to the double-blind treatment. Although the present study is not fully conclusive, apparently because of the use of an inadequate trial design, flunarizine, the first truly promising drug in this disease, deserves further study. An appeal is made to join another international double-blind study.

This 60 year old male developed a right hemiplegia and aphasia. A C.T. head scan showed a cerebral infarct which appeared hyperdense on a subsequent scan done 18 days after presentation. This was interpreted as indicating a hemorrhagic transformation resulting in discontinuation of anticoagulation therapy. At autopsy, the area of infarction in the left frontoparietal hemisphere appeared intensely green due to breakdown of the blood-brain barrier in the presence of jaundice. A striking finding on microscopy was the presence of calcium salts throughout the area of infarction but most prominent in the grey matter at the periphery of the infarct corresponding to the areas which appeared hyperdense on the CT head scan and stained intensely with bilirubin. There was no evidence of recent hemorrhage. This case illustrates that calcification can occur within weeks after the onset of a recent cerebral infarct and should be considered when interpreting the development of C.T. scan hyperdensity in recent cerebral infarcts.

Cerebral ischemia was recorded in 1.9% of 1277 patients with myocardial infarction. In most cases ischemia involved the carotid artery system, usually causing a hemiparesis or hemiplegia. Patients were mostly elderly, and the ischemic episode worsened their prognosis. The pathogenesis was surely often of embolic origin but several facts suggest that other mechanisms were also involved. Anticoagulant therapy, at least in the form in which it was used in these patients, i.e. subcutaneous administration of calcium heparin 5000 I.U. b.i.d. for thrombophlebitis prophylaxis, does not seem to prevent these complications.

Moya moya is an obstructive cerebrovascular disease characterised by peculiar cerebral angiographic features consisting of intracranial stenosis or occlusion of the internal carotid artery or its terminal branches associated with telangiectatic vessels at the base of the brain. Opinion is still divided between a congenital versus an acquired aetiology. Recurrent episodes of sudden hemiplegia, headache and convulsive manifestations occur more frequently in paediatric patients, while subarachnoid bleeding is usually the presenting finding in adults. After a progressive course for many years, the disease frequently stabilizes sometimes with residual disability. Surgical approach to improve cerebral blood flow has been developed but there is a high incidence of complications in pediatric patients. To minimize the defects during ischemic phase, a pharmacological therapy might be useful. We report a new case of childhood moya moya disease which developed a typical angiographic progressive pattern during three years between the first and the latest bilateral study. Clinical course of patient suggest that antiaggregating drugs and calcium antagonists might be useful in this disease although controlled studies are of course needed.

A 32 year old obese, diabetic and hypertensive woman presented with signs of increasing intracranial pressure: diplopia, partial lateralised Jacksonian seizures followed by alternating post-ictal hemiplegia. She was also anaemic. Investigation revealed lead poisoning and thrombosis of the superior sagittal sinus. She recovered rapidly with heparin and calcium EDTA therapy, except for persistent optic atrophy due to the papilloedema. The authors discuss the relation of lead encephalopathy and dural sinus thrombosis, and the contribution of each condition to this patient's clinical symptoms.

No statistical increase in the prevalence of either diabetes, rheumatoid arthritis or primary hyperparathyrodism was found among the hip fracture patient population. Since the relative risks for these diseases is small, the statistics suggest that these conditions are either noncontributory or represent only a minor risk factor in the overall pathogenesis of hip fractures. About 20% of the hip fracture patients had a history of other identifiable risk factors such as thyrotoxicosis, hemiplegia, malabsorption syndromes and corticosteroid therapy. Of these conditions only thyrotoxicosis could be evaluated by comparison of prevalence rates, and a significant increase was found among the fracture patients. A highly significant correlation was found between the side of a previous hemiplegia and side of he subsequent hip fracture; this may be due to the development of disuse osteoporosis in the hemiplegic limb. Recent reports have shown that a reduction in the number of hip fractures is associated with a high calcium intake or prophylactic estrogen therapy. Preventive therapy in patients with hemiplegia, thyrotoxicosis, or other predisposing conditions leading to osteopenia might result in a further reduction of the hip fracture rate.

Intracranial mesenchymal chondrosarcoma is very rare, only 14 cases being reported in Europe and in the United States of America. Recently we experienced a case in which the follow-up indicating computed tomograms (CT) demonstrated interesting data on the radiosensitivity of this tumor. The patient, a 14-year-old female was admitted to out hospital with the complaint of left hemiplegia which had gradually progressed. CT revealed an area spreading upward from the right median base of the skull and consisted of two components showing (A) a density as high as that of calcium and (B) a density higher than that of surrounding brain tissue, but much lower than that of calcium. Temporoparietal craniotomy was performed to react approximately one-half of the tumor. Histological finding revealed mesenchymal chondrosarcoma. The component-A was though to be a cartilaginous tissue, and-B to be an undifferentiated mesenchymal tissue. Postoperative irradiation of 7,000 rad was initiated. The effect of radiotherapy as seen on computed tomograms is as follows, (1) decrease in the volume of the tumor by 26%, (2) decrease in density and enhancement of the area which is considered to be the undifferentiated mesenchymal cells, (3) mild reduction of the area which is considered to be the cartilaginous tissue, and (4) a very high density of the entire tumor similar in degree to that of the bone one year later. These results suggested that radiotherapy is effective for this tumor.

Moyamoya is an obstructive cerebrovascular disease characterized by a cerebral angiographic picture of stenosis or occlusion of main cerebral arteries with an abnormal vascular network at the base of the brain. No definitive cause has been found for this disease and opinion is still divided between a congenital and an acquired etiology. Hemiplegia of sudden onset and epileptic seizures are the prevailing presentation in childhood, while subarachnoid bleeding occurs more frequently in adults. We report a new case of childhood moyamoya with clinical onset of the neurological symptoms within the 3rd year of life; during the child's illness the maternal grandmother presented with moyamoya disease too. Antiaggregating and calcium-antagonist drugs seem effective in preventing further vascular accidents, while a surgical approach is not possible. Computed tomography, single positron emission computed tomography, and magnetic resonance imaging are very useful in the diagnosis of this rare disease.
