Clonazepam (Antelepsin) was tested on 179 patients in 8 institutions during a period of 180 days. 169 patients had been unsuccessfully treated with the usual standard medication and were additionally given Antelepsin. Typical absences and attacks of the West and Lennox syndromes yielded best to treatment with the drug, with favorable effects also being produced in cases of partial or focal epilepsy. The most important side-effect was tiredness, other collateral effects being balance disorders, sensations of dizziness, and musuclar weakness. The frequency of side-effects decreased in the course of therapy. In the electroencephalogram there was observed a significant increase in beta waves and a significant decrease in 3 Hz spike and wave complexes.

Psychoactivity, pharmacodynamic properties and drug tolerance of 2-bromo-4-(2-chlorophenyl)-9-methyl-6H-thieno[3,2-f]1,2-(4-triazolo)[4,3-a][1,4]diazepine (WE 941), a new triazolodiazepine, were studied in 10 normal subjects utilizing quantitative pharmaco-EEG and clinical evaluation methods. In the double-blind, placebo-controlled trial, the subjects received randomized at weekly intervals oral single doses of 0.1 mg, 0.3 mg and 0.5 mg WE 941, placebo, and 30 mg flurazepam as reference substance. Measurements were obtained before and at the 2nd, 4th, 6th h post drug. EEG power spectral density analysis demonstrated no changes after placebo, while WE 941 and flurazepam induced statistically significant alterations characterized by an increase in beta-activity, a decrease in alpha-activity and increase in average frequency ("anxiolytic pharmaco-EEG profile"). In addition, 0.3 mg and 0.5 mg WE 941 and 30 mg flurazepam produced a significant augmentation of delta-activity indicating hypnotic qualities. Considering spontaneous and placebo-induced alterations, evaluation of the time- and dose-effect relationship indicated that all active substances exerted a tranquilizing effect throughout 8 h, while the hypnotic properties of 0.1 mg WE 941 were minimal (up to the 4th h), those of 0.3 mg WE 941 were moderate (up to 6 h) and those of 0.5 mg WE 941 were marked (up to 8 h). The dosage equipotent to 30 mg flurazepam is 0.3 mg WE 941. Heart rate and blood pressure exhibited no relevant changes, while side effects including fatigue, drowsiness and dizziness were mostly observed after the highest dosage of WE 941.

Patients present themselves with neurotologic symptoms which may be early and subtle indicators of active vestibular pathology. The frequently slighted complaints of light-headedness, imbalance and a floating sensation are as important as "true rotatory vertigo." Ear fullness, the most underinvestigated of neurotologic complaints may be a cardinal symptom. Occipital headaches are a frequent complaint of the dizzy patient. Blurred vision, and, in some severe peripheral disorders, diplopia are symptoms referrable to oculovestibular interaction. Visual stimulation intensifies vestibular symptoms. Stress may precipitate or increase dizziness in patients who have partially compensated for a vestibular deficit. Anxiety, fatigue and systemic illness are exemplary. Patient histories are presented to emphasize clinical relevance and therapeutic modalities.

The response to electrocardiographically monitored submaximal exercise stress testing has been studied in 44 patients with mitral leaflet prolapse (MLP). With exercise, ventricular premature contractions occurred in 7, ventricular tachycardia in 1, and atrial fibrillation in 1. Exercise was terminated short of target heart rate in 18 patients, because of chest pain (5), fatigue (7), ventricular arrhythmia (4), dizziness (1) or ST segment depression (1). 23 patients developed postexercise ST segment abnormalities, of whom 5 had 'ischemic' patterns and arteriographically proven coronary artery disease (CAD); among the 18 others, the ST segments were depressed and minimally downsloping in 2, slowly ascending from depressed J point in 3, horizontal for greater than or equal to 80 msec with J depression of less than 1 mm in 12, and cupped in 1. The incidence of arrhythmias provoked by submaximal exercise stress testing in patients with MLP was lower than suggested in previous reports. In all 5 cases where MLP and CAD coexisted, the classical 'ischemic' electrocardiographic response to exercise was not obscured. Even in the absence of CAD, postexercise ST segment abnormalities were common with MLP (18/39 = 46%) and differed from the progressively resolving ST segment deviation characteristic of CAD with angina. Exercise testing can safely be recommended, subject to standard contraindications, in patients with MLP and yields useful information.

During the course of an obscure illness in a teenage girl it was eventually realized that the diagnosis was 'epidemic neuromyasthenia'. The illness which occurred between February and September 1976 was characterized by fatigue, pallor, headache, nuchal pain, alterations in mentation, dizziness, nausea and vomiting, paraesthesiae, weakness and heaviness of limbs, and a prolonged relapsing course. Investigation brought to light fourteen patients with similar symptoms--twelve female and two male. In view of the shortcomings of retrospective enquiries, especially those involving the assessment of notes made by other people, and the problem of trying to define a nonfatal illness with protean symptoms, many of a nonspecific nature, with few physical findings and negative laboratory studies, caution is necessary. Under these circumstances it is claimed on clinical epidemiological evidence that a diagnosis of 'epidemic neuromyasthenia' could be sustained confidently in three patients and probably in a fourth. Six patients were considered possible cases and four were rejected.

The case of a 22-year-old white male without known heart disease who presented with activity related lightheadedness at age 19 and dizziness and fatigue at age 21 is described. Standard electrocardiograms (ECG's) revealed intermittent complete trifascicular block. Rapid progression of symptoms over the succeeding eight months resulted in increasing incapacity. Holter monitoring demonstrated that symptoms were related to development of second and higher degrees of A-V block. Normal A-H interval and markedly prolonged H-Q interval on His bundle electrograms indicated that block was infranodal and localized to bundle branch system. Conduction problems aside, clinical and laboratory evaluation, including echocardiograms and cardiac catheterization, were unremarkable. Progression of bilateral bundle branch disease in a young patient without other demonstrable heart lesions and a negative family background conforms with criteria for Lenegre's disease. To our knowledge, this represents the youngest reported patient with this entity. Possible electrophysiologic basis of block and of exercise induced improvement in A-V conduction also are considered.

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.

This report details our total experience with documented chronic His bundle block in 24 patients. Ten patients had second-degree block (eight with 2:1 block and two with type-1 block), and 14 patients had complete heart block. There were 16 women (67 percent) and eight men (33 percent) with ages ranging from 17 to 87 years. Diagnoses were as follows: hypertensive cardiovascular disease, nine patients (38 percent); arteriosclerotic heart disease, six patients (25 percent); aortic valvular disease, three patients (13 percent); primary conduction disease, two patients (8 percent); primary myocardial disease, two patients (8 percent); congenital heart block, one patient (4 percent); and traumatic heart block, one patient (4 percent). Pacing was instituted in 20 patients because of the following; congestive heart failure, seven patients; syncope, seven patients; fatigue, four patients; and recurrent dizziness, two patients. Permanent pacing was indicated within ten days of initial diagnosis in 13 patients, from 20 to 80 days in four patients, and later than 100 days in three patients. An additional two asymptomatic patients were treated with prophylactic pacing.

Seventy patients presenting symptoms of hysteria (49 women and 21 men) were selected among patients observed at the Institute Minkowska during the year. This work is part of a research work on socio-cultural and environmental factors which can change mental status of immigrants. These are all portugese workers presenting for the first time atypical mental troubles called by the author: "bastard hysterical syndrome of the immigrant" and characterized partly or totally by the following symptoms: fatigue, anxiety, sense of suffocation, dyspnea, coughing, unilateral chills or generalized chil, abdominal or gastric pains, headaches and "diffused pains", paresthesia, aching back, tears and sorrow, fear of dying or having a cancer, asthenia, leg paresthesia and contractions, vomiting, diarrhea, cardiac pains, palpitations, dizziness and collapsing. These troubles appear sometimes without apparent motives but they are almost always due to a precipitating cause expressed by the patient: a delivery, a familial death, a homosexual proposition, a trauma without importance, a working conflict etc... But the most frequent cause invoked is "the french climate" without knowing precisely what the word "climate" means: atmospheric conditions, athmosphere or reception milieu? This latest interpretation seems more likely after months of psychotherapy. Most patients are not french speaking and cannot write; their origin is rural (familial villages well structured regarding their food and sexual economy), and people well "armed" by a system of defense mechanisms and well adopted conditioned reflexes. In this work, hysteria of the portugese immigrant is compared to childhood hysteria. As the hysterical burst of the child is aimed at calling attention, love of the mother, at finding a solution to a familial or social conflict, the hysterical burst of the immigrant is aimed at the absent family or at its substitutes, the bos, social security, the doctor. Furthermore, the attitude of the hosting Country--wanting and rejecting--is very ambivalent; "tenderness" at the time of reception, followed by indifference. Early attentions are followed by constant interdictions (threat of unemployment, false statements on sexual dangers of the immigrant etc;..). The immigrant, like the hysterical child, is periodically controlled (work and visit cards), supervised (supervisors), The narcistic satisfactions of being called a good worker can be followed by threats of firing in economic crisis. The society of the hosting country requires the immigrant to be identical to this society: language, physical appearance, food. The real paradoxical situation to which the immigrant is confronted and the real or hypothetical fears constitute conditions of experimental neurosis, to which portugese immigrants react very often by a bastard symptomatology of hysterical type, characteristic of displaced man. These preliminary studies are the frame for a future epidemiological survey in this specific population.

Clinical, biochemical, haematological and erythrokinetic studies were performed on 63 adult males with prolonged lead exposure. Their most common symptoms and findings were abdominal pain (62%), gingival lead lines (48%), headache and/or dizziness (33%), muscle cramps (32%), anaemia (19%), and fatigue (18%). Colicky abdominal pain (27%) and gingival lead lines correlated with urinary lead excretion. Anaemia was mild, but more frequent in the subjects with the greatest urinary lead excretion. Other associated findings were: higher reticulocyte counts and more basophilic stippling of the RBCs, more sideroblasts and greater erythroid hyperplasia of the bone marrow, more reduction in 51Cr-tagged RBC survival time, smaller RBC mass, a more rapid plasma iron clearance, a greater plasma iron turnover and greater utilization of 59Fe in subjects with urinary lead excretion of greater than 100 microng/day in comparison with the remainder and normal controls. These findings suggest that minimal chronic exposure to lead causes an increased haemolysis with resulting increased production of erythrocytes.
