Among the most important coronary risk factors are a diet rich in saturated fatty acids, cholesterol and calories, hypercholesterolemia, high blood pressure and excessive smoking. The typical pain can be elicited by putting a strain on the patient, e.g. climbing stairs. The disappearance of the pain after treatment with nitroglycerine is one of the most important pointers. Treatment is with nitroglycerine which, moreover, remains the drug of choice, also with nitrates such as pentaerythritol tetranitrate and with betablockers like propranolol. Favorable results have also been reported with a combination of isosorbide dinitrate and propranolol.

In this report the clinical, laboratory, and histopathologic findings of nine children with polyarteritis are reviewed. All have had evidence of systemic involvement. Eight presented with fever, calf pain, erythematous painful nodules, and elevation of the acute-phase reactants. All were treated with prednisone at a dosage of 2 mg/kg/day. All of the children are alive but have had relapses at least once during the course of tapering the dosage of corticosteroids. Serious complications of disease have included myocardial infarction, hypertension, and impaired renal function.

Attempt at evaluation of the operative risk depending on seven factors. 1--For benign tumours (Example: meningiomas): 1--greater than 65 years; 2--functional insufficiency, depending on the type of tumour; 3--the volume of the tumour; 4--site of the tumour; 5--foreseeable operative difficulties; 6--the importance of intra-cranial hypertension and the level of pre-operative consciousness; 7--life expectancy, quantitative and qualitative. II--Extrapolation of the previous equation to malignant tumours, chronic sub-dural hematoma, intra-cerebral hematoma and surgery of pain.

A 35-year-old man ingested food contaminated with lindane, an insecticide containing almost pure gamma hexachlorocyclohexane. Grand mal seizures and severe acidemia developed rapidly. The seizures recurred for nearly 2 hours, then ceased. In addition, the patient had muscle weakness and pain, headaches, episodic hypertension, myoglobinuria, acute renal failure and anemia. Pancreatitis developed 13 days after the ingestion of lindane. A muscle biopsy on the 15th day of illness demonstrated widespread necrosis and regeneration of muscle fibres. The patient's condition improved and he was discharged 24 days after the onset of his illness. During the year following the poisoning the patient noted difficulty with recent memory, loss of libido and easy fatigability. One year after lindane ingestion the results of physical examination, including those for muscle power and bulk, were normal.

Loin pain may be a major presenting symptom in patients with glomerulonephritis. Most of these patients show an underlying focal and segmental proliferative glomeruloneyphritis and there may be associated deposits of IgA and Igg in the mesangium. In this group of patients, vascular lesions are often prominent in the absence of hypertension. Episodes of recurrent macroscopic hematuria also occur, but the pain cannot be attributed to colic due to blood clots in the ureter.

Three new cases of chronic vitamin A intoxication are reported and a review of the literature with special reference to chronic intoxication in adolescents and adults is presented. The most prominent features are intracranial hypertension, skin and hair deviations, pain in the musculoskeletal system, and fatigue. Intracranial hypertension occurs in 50% of chronic intoxications, but is not invariably linked with the other symptoms. Young women are the major age group represented. There seems to be no relation between the severity of the clinical picture and the vitamin A serum level. Discontinuance of vitamin A intake is sufficient for cure.

Prostaglandins are highly potent derivatives of unsaturated fatty acids with multiple biological activities. They are synthesized and metabolized in almost all tissues studied so far. The E- und F-type prostaglandins may be regarded as local modulators of hormonal effects on cell function and--in some cases (kidney, uterus-corpus luteum)--as regional or tissue hormones. Thus they seem to be involved in the regulation of neurotransmission, kidney function, triglyceride metabolism in adipose tissue and progesterone biosynthesis. Apart from their influence on renal blood flow prostaglandins of the A-type possibly have an additional function as circulatory hormones regulating blood pressure. Second messenger-systems (cAMP, Ca++-cGMP) which mediate the effects of most non-steroidal hormones are also involved in the action of prostaglandins, at least of the E-and F-types. Disturbances in prostaglandin metabolism (increased or decreased biosynthesis) are discussed to play a role in the pathogenesis of inflammation, pain, fever, hypertension, bronchial asthma and gastric or duodenal ulcer formation. Drugs with antiinflammatory, analgesic and antipyretic activity have been shown to be potent inhibitors of prostaglandin formation. The correlation of a local prostaglandin deficit or the therapeutic use of single effects of prostaglandins by administration of exogenous compounds (natural prostaglandins or modified derivatives) has so long been less satisfactory because of their large number of biological actions which lead to undesired side effects. Extensive experience have been obtained in the successful induction of therapeutic abortion. This effect is based on the stimulatory action of E- and F-type prostaglandins on the smooth muscles of the pregnant uterus which is resistent to the influence of other stimuli, e. g. oxytocin. Here the incidence of side effects could be reduced by local administration of low doses of prostaglandins into the uterine cavity. A general improvement of the therapeutic usefulness of prostaglandins will however only be achieved, if modified derivatives with more specific actions on the desired "target" tissues are available.

The authors report 45 cases of unilateral renal atrophy. The circumstances of discovery are related to the urological symptoms: pain, hematuria, pyuria. On the other hand, hypertension is rarely the reason for consultation. Women are more affected than men. Intravenous urography, retrograde cystography and arteriography are essential examinations to collect information concerning the etiology. Dynamic scintiscanning with measurement of the percentage of isotope fixed on the kidneys, has the advantage of permitting comparative evaluation of renal function on each side. In our study, obstruction of the urinary tract was more frequent than parenchymatous disease favoured by infection. Vascular abnormalities were rare. The etiological enquiry remained, however, negative in one third of cases. Surgical operation was necessary when a urological abnormality was the cause of persistence of severe symptoms. On the other hand, removal of the atrophic kidney does not seem to us advisable when decided simply to relieve hypertension. The latter point is particularly discussed.

Sixty patients out of 1,844 recovery room admissions had significant postoperative arterial hypertension. Nearly 60% of them had a history of hypertension. The postoperative hypertension usually began within 30 min from the end of operation and lasted about 2 hours. In 20% of the patients it lasted 3 hours or longer. Complications attributable to hypertension were confined to this latter group. The principal factors possibly contributing to the pressure elevations were pain (35%), hypercarbia (15%) and emergence excitement (16%). Ten of the patients (17%) had no demonstrable cause for hypertension. The hypertension in this group appeared to have a shorter and more benign course.

1. Bradykinin (0.02-5 microgram) applied to the epicardium of the left ventricle in the open-chest, anaesthetized dog, elicits dose-related reflex pressor effects and acceleration of the heart rate. 2. Bradykinin-induced reflex tachycardia was suppressed after the blockade of beta-adrenoceptors with propranolol, whereas reflex pressor responses were prevented by blocking the alpha-adrenoceptor sites with phenoxybenzamine. 3. Vagotomy and atropine treatment did not affect reflex hypertension and tachycardia to epicardial bradykinin. 4. After spinal section at C1, the pressor responses to epicardial bradykinin were significantly reduced, but still present in all but one experiment. A small acceleration of the heart occurred in two out of five spinal dogs with intact vagi and was absent in three vagotomized spinal dogs. 5. The results indicate the reflex activation of the sympathetic outflow to the heart and blood vessels, mediated mainly at a supraspinal level as a predominant mechanism for the cardiovascular response initiated by bradykinin-induced stimulation of cardiac pain receptors.
