Preliminary results of this retrospective-prospective analysis of renal hypertension in 110 children indicate that hypertension may be secondary to a wide variety of acute progresive, and chronic renal diseases which may be either congenital or acquired. Affected children may be detected at any time from infancy through adolescence. Symptoms usually associated with acute glomerulonephritis (i.e., headache, swelling, nausea, vomiting, anorexia, fatigue, dizziness, and fever) occur in both acute and chronic renal diseases associated with hypertension. Headache and swelling are the most common symptoms in this series. Peripheral edema, rales, and increased heart size were found in between 10 and 25% of these children. Differential diagnosis may be approached by a consideration of causes of acute and chronic hypertension. The child with chronic renal disease usually presents with a long history of fatigability, poor growth, and pallor, and laboratory tests reveal elevation of the creatinine and BUN along with anemia, hypocalcemia, and hyperphosphatemia. In contrast, the child with acute renal disease and hypertension presents with a history of prior good health followed by the abrupt onset of signs and symptoms of renal disease; laboratory tests usually reveal modest elevations of creatinine and BUN, anemia is unusual, an abnormal urinalysis is common, and serum calcium and phosphorous levels are usually normal. Renovascular and asymmetric renal parenchymal disease represent uncommon but important conditions because surgery may be curative. Treatment may be surgical, medical, or combined. Surgical conditions include renal trauma, hydronephrosis, asymmetric renal disease, and renal arterial disease. Adequate blood pressure control without medication can be expected following surgery in instances of unilateral involvement with a normal contralateral kidney. Meticulous assessment of the contralateral kidney is needed to determine that it is normal. If surgery is unsuccessful or is not indicated, pharmacologic therapy is initiated with a stepwise regimen starting with the mildest agent (e.g., thiazides) and then adding additional antihypertensive drugs when adequate blood pressure control has not yet been achieved. The goal of therapy is the lowest, safest, tolerated blood pressure levels. Long-term, carefully designed studies of antihypertensive agents for children with renal hypertension are not available. The need for collection and critical analysis of data concerning the clinical course of children with renal hypertension is evident from a review of the literature and from the preliminary data presented in this series. The presentation of such information and a critique of outcome variables will provide a basis for program planning for affected children and improvement in patient care where indicated.

Headache is an alarm sympton, whether there is an organic disease (lesional headache) or a perturbation of one of the various functions of the head (functional headache). Lesional headaches follow a sinusitis or an arthrosis, or accompany a "temporal arteritis of Horton". Funstional headaches include several varieties. 1. Trigemellar neuralgia. 2.Vascular algi originating from the basal arteries, the large cerebral venous sinuses or the branches of the external carotid. Among these are: a) headaches due to a dilatation of the internal wall, causing "Horton headache", migraine-like psychosomatic migraine and hormonal migraines (premenstrual, menstrual, menopausal or linked to the use of contraceptive pills); b) headaches caused by an angiospasm of the arteriole, which is the case in exposure to the cold, in traumatic headaches (malfunction of temporomandibular articulation, dry alveolitis), in psychosomatic angiospastic algias and in ethmoidal artery algias preciously described by the author in 1949 (Godin's disease).3. Headaches due to psychic hypertension. 4. Postconcussional psychogenic headaches. 5. Neurotic headaches. The author gives a detailed description of the subjective symptoms in each case, including localisation, from, intensity, duration course and associated phenomenons. This facilitates greatly the differential diagnosis and the choice of complementary examinations. Necessary biological investigations should be performed (e.g. hormonal balance). One should however avoid to increase the number of complementary examination which would only delay treatement and would expose patients to somatisation. Furthermore, in each case drug treatment, periarterial infiltration technics of the temporal, internal frontal, facial, mastoid and occipital arteries are described. The necessity of questioning the patient at lenght and to listen to him to enable him to verbalise conscious conflicts is emphasized. A serious medicopsychlogical examination and a relaxation treatment to reduce anxiety and muscular tension are advised in some cases.

The analgesic syndrome, comprising renal disease, hypertension, peptic ulcer, anaemia and recurrent headache, accounts for wide-spread morbidity and mortality especially in Queensland and New South Wales. Epidemiological and clinical evidence gathered from many Western societies implicates unsupervised consumption of compound analgesic preparations, particularly those containing phenacetin, in the causation of the majority of cases. Laboratory experiments so far have failed to produce an entirely satisfactory model of clinical analgesic nephropathy. In small animals, papillary necrosis results from prolonged feeding with large doses of aspirin and a number of other anti-inflammatory agents more readily than when phenacetin, paracetamol or phenazone is given alone. The apparently conflicting deductive and experimental data may be reconciled if, as indicated by preliminary observations, salicylates enhance the toxicity of phenacetin derivatives. In planning a programme of prevention for the analgesic syndrome, the central aetiological role of non-narcotic drug dependency must be recognized. As the analgesics to which addiction commonly occurs are the compound powders and tablets, or those containing a stimulant, these preparations should be available only in circumstances where their use can be monitored. Suspected unsupervised and unwarranted consumption of analgesics should be checked by urinary testing for drug metabolites. Because the underlying problem of analgesic dependency is behavioural and environmental in origin rather than medical, the physician must combine forces with the social engineer to devise a definitive solution for this condition.

Reports of complications due to estrogen-progestagen combinations are summarized. Common minor symptoms include nausea, abdominal distress, headache, depression, and weight gain. Some of these are directly due to the pill, but others are not; for instance, depression may result from pyrodoxine deficiency, but psychodynamic factors explain the problem in others. Effects on the reproductive organs include secondary amenorrhea in about 2 of every 1000 women; structural and functional changes of the ovaries, uterus, and cervix; increase in incidence of yeast vulvovaginitis; and inhibition of lactation. Most changes in laboratory values of various constituents of blood and other body fluids reflect changes in hepatic function. Thromboembolic diseases, hypertension, and hypertriglyceridemia are rare but more serious conditions for which the pill may be responsible in some cases. Contribution of the pill to carcinogenesis and fetal abnormalities has not been proven.

A case of central nervous system actinomycosis is reported. A 33-year-old male complained of headache, vomiting and blurred vision lasting for eight days prior to admission. On examination, a right hemiparesis, as well an intracranial hypertension were detected. The cerebrospinal fluid showed mild lymphomononuclear hypercytosis. Necropsy disclosed three abscess in the cerebral hemispheres, in addition to moderate cerebral edema on the left side but without purulent leptomeningitis. Actinomyces filaments and granules were demonstrated in the cerebral and lung abscessess. The Brazilian literature on actinomycosis is reviewed and six published cases with nervous system involvement were found. Relevant clinical and anatomical aspects of the cases and of the present one are discussed.

Prolonged ingestion of mixed analgesics containing phenacetin has been associated significantly with the development of a chronic interstitial nephritis frequently associated with papillary necrosis. This disease is frequently underdiagnosed. If an adequate history of headache and/or backache (of which most of these patients complain) is not taken, the central causative effect of phenacetin ingestion may never be appreciated. Laboratory tests show the usual abnormalities seen in any form of chronic interstitial nephritis such as poor urinary concentration, renal failure with large urine output, and no hypertension. Papillary necrosis is helpful but not pathognomonic. The type of medications ingested appears to be changing to prescription compounds. The with significant improvement in renal function.

Restovar, a low dose combined oral contraceptive containing .75 mg lynestrenol and 37.5 mcg ethinyl estradiol was given to 83 women for up to 25 cycles or 1265 total. A cycle contained 22 pills begun on the first day of menstruation or withdrawal bleeding from previous pill cycles. Each woman was questioned regularly on side effects and bleeding, had weight and blood pressure taken, and received gynecologic exams before and after pill treatment. There were no pregnancies. Latency from end of the cycle to bleeding was 2-3 days in 87%; cycles lasted 28 days in 80%; bleeding lasted 3-4 days in 84%; flow was moderate in 72%; and spotting occurred in 4.2% of cylces and breakthrough bleeding in 2.4%; withdrawal bleeding was absent in 4.2% of cycles. The most common side effects were breast pain in 1.9% of cycles and headaches in 1.2%. These complaints as well as nausea, vomiting, leucorrhea, nervousness and depression were reported as less frequent or absent more often than present or aggravated. 6 women quit for drug related reasons. There was no significant weight change or hypertension (means 126/82 and 120/80 before and during Restovar. Thus this low dose pill is remarkably effective and well tolerated.

Information about headache was collected from a nonclinical sample of 451 women, aged 15 to 44, in 12 major U.S. cities. Questions were asked in regard to the presence in the past year of headache, and of the following characteristic symptoms of migraine: unilateral location, throbbing quality, visual aura, vomiting, and severity sufficient to affect daily activities. Twenty-three percent of the women had headaches with two or more of these characteristics. The frequency of such symptoms was significantly greater in women who smoked or formerly had smoked cigarettes, in women with lower incomes and poor education, and in women with a history of hypertension, stomach ulcer, fainting, and a variety of emotional complaints. The frequency of reported symptoms of migraine did not vary significantly according to age, race, marital status, use of oral contraceptives, or number of living children. These findings do not support the commonly held clinical impression that migraine is uncommon among blacks or among the poorly educated.

2 women complaining of headaches were found to have benign intracranial hypertension with increased rCBV (regional cerebral blood volume) of 85% and reduced rCBF (regional cerebral blood flow) of 10%. A lumbar puncture was done showing a small rCBV reduction of 13% but no significant change in rCBF. The patients were also administered 1.5 gm/kilogram body weight of glycerol 3 times a day. After 18 weeks of glycerol treatment, headaches and papilledema disappeared, rCBV and rCBF returned to normal levels, and cerebrospinal fluid pressure was reduced. It is believed that all 3 intracranial compartments may be involved in producing intracranial pressure in benign intracranial hypertension patients although it is difficult to determine the varying degrees to which each factor may be involved. The intracranial pressure may be increased due to venous engorgement and increased CBV. Because of undesirable side effects after long term use of deramethasone and diuretics like furosemide, oral glycerol therapy is used for prolonged therapy without adverse reactions.

Bilateral intracranial occlusion of the internal carotid arteries (Moya Moya) is more common in Japan and occurs more often among women. In a family of 14, 2 sisters and 1 brother were found to have occlusive disease of the intracranial vessels, and 4 siblings were investigated for severe headaches but had normal findings. The 3 siblings had one or more cerebrovascular attacks and a typical cerebral angiogram. One of the sisters, 32 years old, had used the pill before the occurrence of the disease. The arterial occlusion was typical of Moya Moya and not attributable to the pill but the pill may have precipitated the symptoms. Moya Moya has been reported as a cause of meningitis, encephalomeningitis, autoimmune disorders, or even hypertension; however, most cases do not indicate a cause. It has been suggested that Moya Moya is a hereditary disease due to the frequency of siblings with the disease.
