A 27-year-old man was admitted to our hospital for his legs' numbness of subacute onset and
discomfort
while standing. No specific previous history was found and his family history was non-contributory. On admission, his general status was unremarkable except for arterial
hypertension
and mild tachycardia. Moderate impairment of superficial sensations and dysesthesia were noted in the distal extremities, tongue, oral cavity, and lips. Deep sensation was moderately impaired in the lower legs. Romberg sign was positive. He had mild weakness in the proximal muscles of the lower extremities. Hyporeflexia was noted in all extremities, but Achilles reflexes were absent. Pathologic reflexes were not noted. He fainted after two minute standing. On laboratory examination, serum IgM, C3, and C4 were mildly elevated. CSF protein level was prominently high without CSF pleocytosis. MCV was mildly decreased, and F wave conduction velocity was prominently decreased in the posterior tibial nerve, SCV was also mildly decreased in the right sural nerve. Needle electromyography showed mild neuropathic changes. Left sural nerve biopsy showed no abnormal finding in the myelinated and unmyelinated fibers. A 60 degree head-up tilting test caused a hypotensive attack, and Valsalva ratio was decreased. However, hand grip test and cold pressor test were normal. The response to noradrenaline infusion test and CVR-R were also normal. Muscle sympathetic activity (MSA) was recorded from the tibial nerve using a tungsten microelectrode (Iwase, et al.). His basic activity was higher and responsiveness was lower than age-matched normal controls. The regression line existed above the normal range.(ABSTRACT TRUNCATED AT 250 WORDS)

Even in patients with complete loss of sensation and paraplegia after cervical spinal trauma, abdominal operations usually require general or spinal anesthesia due to spasms and increased muscle tone. Both anesthetic types have serious drawbacks under these circumstances, e.g. hyperkalemia induced by relaxation or the impossibility of adequate monitoring of the level of spinal blockade. After an onset time of 1-2 h the intrathecal injection of approx. 100 micrograms baclofen, a spinally acting GABAB-agonist, led to complete and long-lasting suppression of surgically induced spasticity. This could be demonstrated by neurological examination (spasticity scores: Ashworth score, spasm score, clonus score) during 5 neurosurgical operations in 3 patients with paraplegia. Except for slight sedation, the patients had no
discomfort
during operation. Intrathecal baclofen was also effective against autonomic hyperreflexia, i.e. vegetative dysregulation such as bradycardia or
hypertension
, provoked by catheterization or bladder surgery.

We describe 3 patients with painful intraarticular knee effusions composed of a viscous milky white suspension of monosodium urate crystals, in the absence of any cellular component. Two patients presented with acute bilateral knee pain. One patient presented with unilateral knee pain of gradual onset. All 3 patients had a history of ethanol abuse. Two patients had a history of gout. Two patients had chronic renal insufficiency,
hypertension
, and congestive heart failure. One patient had alcoholic cirrhosis. Two patients' pain responded to colchicine. One patient's
discomfort
was relieved only by repeated arthrocentesis. We conclude that intraarticular free urate can cause painful joints in the absence of an apparent inflammatory response.

PTA is an established method of revascularization in a variety of medical conditions. It is performed for specific morphologic and clinical indications. PTA is the procedure of choice in Fontaine stage IIB through IV lower extremity ischemia due to iliac and/or femoropopliteal stenosis or short occlusion. Its role is less certain in infrapopliteal disease, although current studies have begun to establish long-term effectiveness. PTA is the procedure of choice for renal revascularization in renovascular
hypertension
due to fibromuscular disease or non-ostial atherosclerosis, selected cases of renal artery stenosis associated with renal insufficiency, and transplant renal artery stenosis. It is also useful in treating the renovascular component of complex
hypertension
and may be indicated in severe renal artery stenosis (75%-99%), even in the absence of clinically demonstrable RVHTN. PTA has limited applications in the venous system and only short-term success in the treatment of stenoses in dialysis access fistulas. PTA often serves as an important adjunct to surgical revascularization by providing improved inflow or outflow. PTA is the procedure of choice when anatomically feasible in subclavian steal syndrome. The role of PTA in carotid artery disease, particularly atheromatous disease of the internal carotid artery, is uncertain. The same may be said of PTA for vertebral artery stenosis, although the overwhelming majority of vertebral artery stenoses are morphologically suitable for PTA. PTA and surgery are both effective in the treatment of abdominal angina. There are more data available to verify the long-term patency of thromboendarterectomy and bypass grafts than PTA for mesenteric ischemia. However, since the technical success for PTA is high and since coronary co-morbidity is the most common cause of perioperative mortality in surgical series, PTA should be seriously considered as the procedure of first choice. Serious complications of PTA occur in approximately 5% of cases. Two to three percent of PTA patients have complications requiring surgery or causing a prolongation or alteration of hospital course. The morbidity, mortality, and cost associated with PTA are low. The
discomfort
is minor, and postprocedural recovery rapid. The major limitations of PTA include its unsuitability for some lesions (long-segment occlusions and stenoses, orifice lesions, eccentric lesions) and postangioplasty restenosis. These problems are being addressed by ongoing laboratory and clinical research. In the near future, it is likely that endoluminal transmural sonography of the vessel wall will help guide our interventions.

This was a multicenter, randomized, double-blind, parallel-group study of the efficacy and safety of dilevalol, 200 mg (n = 86), compared with enalapril, 20 mg (n = 92), administered once daily to patients with mild
hypertension
. Three weeks of placebo washout were followed by 4 weeks of comparative treatment. Beginning with the first week of treatment, both drugs substantially decreased blood pressure from baselines of approximately 160/100 mm Hg. Decreases in systolic pressure were comparable throughout treatment, but dilevalol tended to have a greater effect on diastolic pressure. At the end of double-blind treatment, average decreases in blood pressure with dilevalol and enalapril were 16/13 and 16/11 mm Hg supine and 15/13 and 15/10 mm Hg standing (p = 0.03 for between-group comparisons of standing diastolic pressure). More dilevalol- than enalapril-treated patients achieved a diastolic pressure less than 90 mm Hg; 73 vs 55% (p = 0.02) supine, and 69 vs 43% (p less than 0.01) standing. The safety profiles of the 2 drugs were comparable. The incidence of adverse effects was low, and few patients discontinued treatment. Headache and gastrointestinal
discomfort
were reported in both groups. Average postural changes in blood pressure were similar to baseline. Electrocardiographic changes were rare and not treatment related. Changes in laboratory test results were minor. Heart rate decreased modestly with dilevalol relative to enalapril (6 vs 2 to 3 beats/min; p less than 0.01), but no bradycardia was observed.

A double-blind, placebo-controlled trial was carried out in 40 patients affected by multi-infarct dementia to see if a daily intravenous infusion of 3 mg co-dergocrine mesylate ('Hydergine') over 14 days would improve severely deteriorated elderly patients and shorten the latent period (3 months) which is observed when the drug is given orally. All the patients had severe mental impairment, psychological deficit or altered consciousness. A Hachinski score of 7 or more, and a cumulative score of at least 12 points on SCAG scale Items 1, 2 and 4 (anxiety/depression) and/or Items 5, 6 and 8 (alertness/confusion) were required for admission. After 1 week of intravenous infusion of placebo, patients were randomly allocated to treatment with co-dergocrine mesylate or placebo, from Day 1 to Day 14. The solutions were infused over a period of 2 hours. During the follow-up period from Day 15 to Day 21, the patients did not receive any treatment. Thirty-six patients (17 on co-dergocrine mesylate, 19 on placebo) completed the study. The results, as rated on the SCAG scale, indicated significant improvements, in favour of co-dergocrine mesylate, in cognitive dysfunction, mood depression, withdrawal and overall impression. Furthermore, the factor fatigue on the Nowlis scale and clinical global assessments by physicians also showed significant advantages of the co-dergocrine mesylate group over placebo. Nine out of 17 co-dergocrine mesylate patients complained of side-effects, usually experienced during infusion; they consisted mainly of nausea (6 patients), gastric
discomfort
(2 patients), and tremor, nasal congestion, flushing, hypotension and
hypertension
(1 patient each). Despite the appearance of side-effects, general tolerability was rated as 'good' by both physicians and patients. It is concluded, therefore, that intravenous high dose co-dergocrine mesylate treatment has a fast and clinically relevant effect on the key clinical symptoms of multi-infarct dementia.

To investigate the relationship between job-stress and blood pressure increase, 373 male blue collar workers without
hypertension
were followed for one year. 5 kinds of perceived job-stress were assessed by means of mailed questionnaires. Stepwise multiple regression analysis was conducted to examine significant determinants of blood pressure increases during follow-up. Job-stress due to complicated machine operation was found to be a significant predictor of diastolic blood pressure increase independent of other significant factors, i.e., systolic and diastolic blood pressure at the beginning of the follow-up, age, total serum cholesterol, alcohol consumption, type A behavior and family history of
hypertension
. Job-overload, physical
discomfort
, human relations and job-dissatisfaction, on the other hand, bore no significant relation to systolic and diastolic blood pressure increases. The results suggest that the use of production machines involving complicated operations and newly developed technology might be a risk factor for high diastolic blood pressure.

In an eight-week, multicenter open-label study of enalapril monotherapy for mild-to-moderate essential hypertension, data for 115 of the 276 participants between the ages of 55 and 75 years (whites, n = 90; blacks, n = 25) were analyzed. These data were compared with similar data for the study subset of 92 younger patients between the ages of 21 and 45 years (whites, n = 58; blacks, n = 34). The most striking finding was the overall lack of significant differences in response between older and younger patients. There were, however, significant differences in response to therapy between the two racial groups studied. In the older group, normotension was achieved in 66% of white patients and 60% of black patients with a single daily dose of enalapril ranging from 5 to 40 mg; the group means, 13 +/- 1 mg in whites vs 22 +/- 2 mg in blacks, differed significantly (P less than 0.05). Thirty-one percent of older white patients attained normotension with a daily dosage of 5 mg, whereas only 4% of black patients in this age group did so. Only 4% of the older white patients but 24% of the older black patients reached the highest recommended daily dosage of 40 mg of enalapril. Adverse reactions occurred in 11% of the older white patients and 16% of the older black patients (a nonsignificant difference), consisting mostly of gastrointestinal
discomfort
, malaise, dizziness, and pruritus. There were no significant biochemical abnormalities, the only consistent change being a slight increase in mean plasma potassium from 4.34 to 4.45 mEq/L in older whites (P less than 0.05). Enalapril appeared to be generally effective and well tolerated in the management of mild-to-moderate
hypertension
in the older subset of patients in this study. Efficacy and tolerability data for older and younger patients were comparable.

We studied a patient with a very small somatostatinoma that arose from the prominence of the orifice of the duct of Santorini. The patient presented clinically with epigastric
discomfort
, marked loss of weight, diarrhea, exertional dyspnea, and chest pain. He flushed intermittently and had occasional tachycardia and
hypertension
. Levels of serum serotonin and urinary 5-hydroxyindoleacetic acid were normal. A small ampullary tumor was resected and identified by immunohistochemical staining to be a somatostatinoma. The patient had gained 6.75 kg and was essentially free of symptoms 16 months after surgery.

There is currently much concern over the morbidity and mortality of donors undergoing nephrectomy for living related renal transplants. Between April, 1970 and July, 1986, 247 cases of living related renal transplants were performed at the Second Department of Surgery, Kyoto Prefectural University of Medicine. The average age of the donors was 50.3 +/- 9.7 years, 81 per cent of the donors being parents of the recipients. Minor abnormalities which did not affect the donors suitability were found in 71 cases. Nephrectomies were performed extraperitoneally in all cases. Peri-operative complications, including wound complications in 13 cases, urinary infection in 12 cases and pulmonary complications and arrhythmia in 4 cases, were considered to be minor in nature. A variety of renal function tests, carried out two weeks after nephrectomy revealed normal levels, although they had become slightly worse than those estimated pre-operatively. Long-term sequelae in the follow-up period from 18 months to 16 years and 2 months, was studied on 124 donors who answered questionnaires. Currently, there are 5 late deaths, none of which are directly related to the nephrectomy. Of the 124 donors, 85.5 per cent stated that there had been no change in their physical states following surgery. Pain or a feeling of
discomfort
at the wound site was reported by 10 donors (8.1 per cent) and
hypertension
was observed only in 3 (2.4 per cent). No major complication directly related to the donor nephrectomy was found, except for one case of incisional hernia.(ABSTRACT TRUNCATED AT 250 WORDS)
