The first symptoms of the disease encountered in 30 patients were paresthesia, constant dull headaches and a feeling of numbness of the face or its half. Eventually weakness, atrophia of the masticatory muscles, a drop or absence of the corneal reflexes and cerebral and focal symptoms super vened (the symptoms depended upon the direction of the neurinoma growth). Signs of hypertension were seen in 17 cases. There was also a protein-cell dissociation: 0.5--7% of protein in pleocytosis 6/3--68/3. The craniograms showed a destruction of the ground of the middle cranial cavity in 24 cases, while in 23 cases there was a destruction of the pyramidal apex. Antiographic studies demonstrated a displacement of the carotid siphon medially (18 cases), forward (8 cases) or behind (5 cases). The tumor vascular network was detected in 5 patients. The diagnosis of neurinomas of Gasser's node requires a comprehensive summarization of the clinical and x-ray findings.

We describe a patient with papilledema due to benign intracranial hypertension who had sudden, painless monocular visual loss. Fear of further visual deterioration prompted vigorous therapeutic efforts to reduce intracranial pressure. Subsequent neuro-ophthalmologic evaluation disclosed that the visual loss was due to a subretinal neovascular membrane. Vision continued to improve after medical therapy was discontinued, and was accompanied by complete resolution of papilledema and headache. In any patient with minimal papilledema, sudden visual deterioration should initiate a search for other causes rather than zealous therapeutic efforts to reduce intracranial pressure.

Benign intracranial hypertension, an unusual case of headaches, was associated with pregnancy in a gravid female with the chief complaint of headache. Symptoms resolved after three days of prednisone therapy. In benign intracranial hypertension, the possibilities of intracranial mass lesions, intracranial infection, obstruction of the cerebral ventricles, and hypertensive encephalopathy are excluded by evaluation with skull films, computerized axial tomography, electroencephalography and lumbar puncture. The only symptom may be headache and the only physical sign, papilledema. Therefore, neurological examination must include visualization of the fundi.

A 17-year-old woman manifested fever, abdominal pain, headache, and hypertension caused by a solitary, benign pheochromocytoma. She also had hypercalcemia and elevated plasma immunoreactive calcitonin levels. After removal of the pheochromocytoma, calcium and calcitonin levels returned to normal. Studies of peripheral and tumor venous blood showed no excess or ectopic parathyroid hormone secretion, but the tumor contained and secreted calcitonin. Sporadic pheochromocytoma may secrete calcitonin and cause hypercalcemia by non-parathyroid hormone-mediated mechanisms. The potential is clearly present for confusion with multiple endocrine neoplasia, type 2 (medullary thyroid carcinoma, pheochromocytoma, and primary hyperparathyroidism).

The case histories of 125 children with hypertension and no apparent primary CNS disease were analyzed for neurological symptoms or complications. Eleven children had neurological symptoms of high blood pressure. In only one of these patients was the diagnosis of arterial hypertension made before the observation of the neurological findings. The symptoms were severe headache in eight children, convulsions and coma in four, hemiplegia in two, and impaired vision and apraxia in one child. Symptomatology was rapidly reversed by antihypertensive treatment in four children, while six had long-term stigmata and one child died in hypertensive crisis. Because elevated arterial pressure can cause severe neurological disease, routine blood pressure measurement in children--especially those with neurological symptomatology--is stressed.

A sleep apnea syndrome due to upper airway obstruction was diagnosed in 25 adult men (25 to 65 years of age) using nocturnal polygraphic monitoring. Excessive daytime somnolence, hypnagogic hallucinations, and automatic behavior, personality changes with abnormal behavioral outbursts, impotence, morning headaches, abnormal motor activity during sleep, nocturnal enuresis, and high blood pressure should suggest this diagnosis when any of the symptoms are associated with loud snoring. Respiratory monitoring during sleep and nocturnal cardiovascular evaluation bring prognostic information and indications for therapy. Three types of therapeutic trials, namely, diet, medications with or without diet, and surgery have been performed. Only surgery has been beneficial in these cases.

A detailed questionnaire concerning life history of headache and its characteristics was administered to 1,809 nonmedical volunteers. Questions dealt with severity of headache, the nature of preceding and accompanying phenomena (nausea, visual scotomata, neurologic symptoms), precipitating factors, and history of other illness. For the total sample and in the 25 to 39 age group, severe or disabling headaches were significantly more frequent in women and mild headaches were significantly more common in men. Migraine characteristics were common with mild headache. An association between hypertension and severe headache was found in women, between asthma and severe headache in men.

Guancydine (1-cyano-3-tert-amylguanidine) lowered within normal limits the tensional values in an interval of four hours after its administration in eight out of nine hypertensive patients under experiment. The hypotensive effect of a single oral dose of 500-750 mg persists for about 6-7 hours after its administration. Guancydine does not impair the vasopressor response to angiotensin II but reduces the action of this peptide on the excretion of water, Na, K and Ca through urine. The hypotensive effect of Guancydine is associated with a decrease of platelet adhesiveness and an activation of fibrinolysis. In view of this fact, Guancydine might play a role in the prophylaxis of complications of arterial hypertension - atherosclerosis and trombosis. The increase of venous blood oxygenation after Guancydine could be attributed to the opening of arterio-venous shunts or to the reduction of tissular extraction of oxygen. Guancydine does not seem to be toxic. It produced, in some patients, slight headache and orthostatic hypotension, especially during the first hours after administration.

Despite the recent publicity given to studies pointing out the negative side effects associated with the use of oral contraceptives, the pill is still the most common form of contraceptive used in Great Britain and constitutes the form of contraception for many women. Some of the negative effects currently receiving wide publicity, no longer represent a serious threat for the pill user; many of these effects have been negated or ameliorated by modifying the composition of the pills. In combined pills the estrogen content has been reduced from 150ug to 20-35ug. In the 2 major studies linking oral contraceptives with the development of cardiovascular disease most of the women in the studied population had taken pills containing 50-100ug of estrogen. Given the wide choice of pills currently available, many of the negative effects, such as nausea and pain, cna be ameliorated by choosing a more appropriate oral contraceptive for the specific patient. Other side effects such as headaches and poor cycle control can be treated by regimen modification. Although there is a relationship between pill use and hypertension, pills containing levonorgestrel in combination with 30ug of ethinyloestradiol have only a slight effect on blood pressure. Lactation is not reduced for women who take progestogen only pills. Fertility is successfully restored in almost all women shortly after they stop using the pill. Drug interaction failures can be avoided in many cases by prescribing pills containing 50ug of estrogen for women taking other drugs. In order to obtain immediate effectiveness, the combined pill can be started on the 1st day of the period instead of waiting until the 5th day.

The effect of tolamolol 50-300 mg three times daily in the treatment of 30 patients with mild-severe hypertension was studied. The duration of therapy in the majority of cases was 3-6 months. There was a highly significant reduction of mean blood pressure (p less than 0.001) for the group as a whole. Overall, 61% of patients became normotensive or showed a reduction in severity of hypertension, In the majority of cases, this improvement occurred within the first four weeks of therapy. There was not postural hypertension. Apart from one patient with Prurigo Besnier who developed asthma, another patient who developed severe headache and a third patient who stopped treatment without giving a reason, treatment was well tolerated and there were no other serious side or toxic effects.
