Since 1924, when ependymomas were first classified as a distinctive glial neoplasm by Bailey, much has been published concerning these tumors, but there are important points of interest that are still not clear. In order to study more fully the clinical and pathologic characteristics of the ependymoma, we identified 62 patients with histologically proven neoplasms. Twenty-two were supratentorial, 21 were infratentorial, and 19 were intramedullary spinal cord tumors. These groups had mean ages of 17, 7, and 41 years, respectively, at the time of first symptoms. The presenting and accompanying symptoms were related to location and included headaches, nausea, visual changes, hemiparesis, and neck, back, and radicular pain. Neurological signs included papilledema, nystagmus, gait disturbance, cranial nerve palsies, altered mental status, paraparesis, and sensory dysfunction. Radiologic modalities of particular importance included computed tomography and myelography. Surgery and radiation therapy were the primary treatment modalities with median survival times from first symptoms being 92, 36, and 117 months for the above groups, respectively. Based on computer-generated survival curves, several characteristics significantly affected survival. These included tumor site, age, and neuraxis metastases. In patients with supratentorial tumors, cranial nerve palsies, microcystic changes, and mitotic figures were important, while in patients with infratentorial tumors, widened sutures, increased head circumference, age, epithelial features, and subependymal features significantly affected survival. Patients who had complete gross resection of a spinal cord tumor had no recurrences or mortality.

15 patients aged between 24 and 66 years with 10 different malignant tumor diseases were treated with a recombinant human tumor necrosis factor preparation PAC-4D in a phase-I trial. The starting dose was 10(5) U PAC-4D as an intravenous short infusion. The maximally tolerable dose is around 18 X 10(5) U/m2. As the main clinical side effects were observed: fever, chills, hypertension with subsequent hypotension, lethargy, transient somnolence, headache, neurological deficiency symptoms, nausea and vomiting. Important laboratory-chemical parameters were the increase in transaminases and, in higher dose levels, leukocytosis with the left shift and lymphopenia in the differential blood picture. As dose-limiting toxicity are estimated hypotension, and neurological side effects and hepatotoxicity. In one female patient who received 27 X 10(5) U PAC-4D there appeared pronounced, histologically verified necroses in the metastases of a malignant fibrous histiocytoma.

We analyze a series of 44 medulloblastomas in patients aged 20 and older, listed in the Connecticut Tumor Registry. Average age was 34.1 years. Incidence was 0.058 per 100,000 per year. Headache and ataxia were the most frequent presenting complaints. Findings at diagnosis most often were papilloedema, cranial nerve palsies, and cerebellar dysfunction. Treatments included operation (15%), radiation (7%), and operation plus radiation (60%). Probability of survival at one year was 0.62; at five years, 0.26. Survival with operation and radiation was superior to survival with other courses of treatment. Extracranial metastases to the spinal cord, the bones, and the pleura occurred in 27% of cases. For the first two years from diagnosis, survival in this series was significantly better than survival in the contemporary series of children with medulloblastoma. At five years and ten years, survival in adults and children was comparable.

A patient was admitted to the Emergency Department of the Montreal General Hospital and referred to the Ophthalmology Clinic. He reported disorientation, dizziness, frontal headaches, and near vision problems. He had reduced near vision, binocular vision anomalies, Collier's sign, and abnormal pupil sizes, shapes, and responses. A diagnosis of pinealoma with a poor prognosis due to metastases was made.

A 55 year-old man complained of headaches, dizziness and vomiting. Neurological examination only showed a cerebellar syndrome. CT scan revealed two hyperdense round areas in the right frontal lobe and cerebellar vermis consistent with metastases and a lung carcinoma was diagnosed. Two months later he presented with typical right hemichorea. A second CT scan showed another hypodense lesion with slight contrast enhancement in the left subthalamic region. He died 6 months after clinical onset. Post mortem examination showed an adenocarcinoma of the right lung with liver metastases. Neuropathological examination revealed four intraparenchymatous metastases one of which involved the left subthalamic nucleus. Hemichorea secondary to metastatic neoplasm of the corpus Luysii is uncommon; only 6 cases have been reported previously; five of them had a post mortem examination of the brain. In three cases a CT scan was available and had demonstrated the site and nature of the lesion.

The effects of a single 2 mg oral dose of molsidomine were assessed with treadmill multistage exercise testing in six men with stable angina. A double-blind, placebo-controlled protocol was used, with exercise to the point when anginal pain forced the patient to stop. Exercise was undertaken before and at 1/2, 1 1/2, 4, and 6 hours after drug administration. Molsidomine improved exercise performance, with the best antianginal effect at 1 1/2 hours after administration, when the mean times to limiting angina were approximately 6 3/4 minutes with placebo and 11 1/2 minutes with molsidomine (p less than 0.05). The corresponding energy expenditures were 33.8 and 77.6 mets, an increase of 130% with the active drug. Intra-arterial blood pressure recording verified that molsidomine had a vasodilator hemodynamic profile, and the immediate postexercise rate-pressure product 1 1/2 hours after molsidomine treatment was 232 mm Hg/min X 10(-2), compared with 183 mm Hg/min X 10(-2) after administration of placebo (NS). Side effects of molsidomine were limited to headache in two patients.

This paper presents two cases of Rouviere node metastasis in carcinoma of the hypopharynx as confirmed by gallium scintigraphy. Invasion of the Rouviere nodes was clarified within six months of the onset of symptoms in both cases. One patient eventually died of intracranial cancerous invasion and the other remains in the terminal stage of cancer with multiple bone metastases. It was hitherto believed that metastases to the Rouviere nodes were extremely difficult to diagnose in the early stages. However, it is now apparent that the neurological signs and symptoms which commonly appear in patients with cancerous invasion of the jugular foramen syndrome facilitate early diagnosis of the disease, the most common symptom being a headache.

A case of nontraumatic chronic subdural hematoma due to obstruction of dural vessels by tumor cells is presented and 25 reported cases are reviewed. A 39-year-old female was referred for headache, vomiting, disturbance of consciousness and right homonymous hemianopia with macular sparing. She had undergone mammectomy for medullary nodular carcinoma of the left breast five years before. She had been treated with combined hormonal therapy and chemotherapy for the cancer metastases to the liver in preceeding six months. Hematological examination revealed drug-induced thrombocytopenia, increase of FDP in blood (80 micrograms/ml), but no abnormality of prothrombin time and fibrinogen content. Therefore in the present case there was no evidence of disseminated intravascular coagulation (DIC) after Colman's criteria. However, it was suggested that this case had compensated DIC after Cooper's criteria. CT scan showed a biconvex-shaped low and partially iso-density area over the left fronto-temporal convexity, indicative of chronic subdural hematoma, and no abnormal findings in the occipital area. After removal of the hematoma she became alert without headache and vomiting. However, seven days later she complained of headache and vomiting again. Repeated CT scan showed a larger biconvex-shaped low density area over the left hemisphere extending to the parietal region at that time. Second operation was performed, but she expired four days later. Autopsy showed systemic metastases of the medullary nodular carcinoma in the scalp, temporal muscle and dura as well as lungs, adrenal glands, ovaries and bone marrow.(ABSTRACT TRUNCATED AT 250 WORDS)

In a series of 24 pheochromocytomas, four were tumors in the organ of Zuckerkandl. Their presenting symptoms of headache, palpitation, diaphoresis, and anxiety were similar to symptoms of adrenal pheochromocytomas. Two patients had paroxysmal and two patients sustained hypertension. All four had elevated urinary vanillylmandelic acid, metanephrine or catecholamine levels. Two of the tumors were localized with angiography before the availability of computerized tomography. Two patients underwent initial computerized tomography, which was nondiagnostic. Later scans looking specifically for organ of Zuckerkandl tumors were positive. Organ of Zuckerkandl tumors, like other ectopic pheochromocytomas, have a higher rate of malignancy. Two of the four were malignant tumors. One patient died 4 years after operation, but the other patient remains stable despite metastatic disease 8 years after operation. The two patients with benign tumors remain well 2 and 3 years after resection and treatment with alpha-blockade.
