A school-based treatment model for pediatric obsessive-compulsive disorder.

School psychologists have expertise in the realm of school-based assessment and intervention for behavioral, educational, and psychological difficulties. Recent evidence indicates that many school psychologists lack evidenced based knowledge about assessment and treatment of pediatric Obsessive-Compulsive Disorder (OCD). Pediatric OCD is a relatively common disorder that contributes to substantial impairment in educational and psychosocial domains.

Electrocardiographic abnormalities in patients receiving hemodialysis.

We assessed standard 12-lead and Holter electrocardiographic (ECG) abnormalities in maintenance hemodialysis (HD) patients. Of 221 outpatients receiving HD, 143 (65%) had ECG abnormalities. Rates were higher in male, elderly, hypertensive, and diabetic patients than in female, younger, normotensive, and nondiabetic patients.

Angiotensin-converting enzyme inhibition, the sympathetic nervous system, and congestive heart failure. The Australian Zestril (Lisinopril) Study Group.

Catecholamines have been found to be powerful indicators of prognosis in patients with congestive heart failure. However, it is uncertain whether catecholamines are a marker for decreased cardiac performance or part of the pathologic process. Catecholamines, exogenously derived beta-adrenergic stimulants, and drugs that amplify sympathetic responsiveness produce early hemodynamic benefits, but do not appear to provide long-term improvement in terms of symptoms or exercise tolerance, whereas blockade of the beta-adrenoceptor appears to have little early benefit but may improve long-term prognosis.

Blood pressure changes with age in two ethnic groups in Fiji.

Blood pressure was studied in urban and rural samples of the Melanesian and Indian populations of Fiji during a National Cardiovascular Disease and Diabetes Survey in 1980. Mean blood pressures rose with age and tended to be higher in urban than in rural populations, particularly in the middle age range. There was no clear or significant difference between the ethnic groups.

Cardiac surgery in a private hospital. With special reference to coronary artery surgery.

In a four-year period in a private hospital there were 1396 open heart operations of which 1275 were for isolated coronary artery disease. The various techniques that were used for coronary artery reconstruction were saphenous vein grafts and internal mammary artery grafts, both singly and sequentially, and endarterectomy. The operative mortality for isolated coronary artery surgery was 1.

Prevalence of diabetes and impaired glucose tolerance in the biracial (Melanesian and Indian) population of Fiji: a rural-urban comparison.

Rural-urban and ethnic comparisons of impaired glucose tolerance and diabetes mellitus were made in the biracial population of Fiji in 1980. No statistically significant differences existed in age-standardized impaired glucose tolerance prevalence between rural and urban groups or between Melanesians and Indians. The age-standardized prevalence of diabetes in the rural Melanesian male population was one-third that of the urban male population (1.

Comparison of lead complications with polyurethane tined, silicone rubber tined, and wedge tip leads: clinical experience with 822 ventricular endocardial lads.

Lead-related complications have been prospectively studied for 602 unipolar tined endocardial ventricular pacemaker leads implanted over a five-year period. No differences were noted in overall complication rates between 238 polyurethane insulated leads (4.2%) and 364 silicone rubber insulated leads (3.

Electrophysiologic studies in survivors of late cardiac arrest after myocardial infarction.

Nine patients resuscitated from life-threatening ventricular arrhythmias (VA) within 3 months of an acute myocardial infarction (AMI) underwent electrophysiologic studies (EPS) with clinical follow-up for at least 12 months. Neither reinfarction, drug therapy, nor electrolyte imbalance was a precipitating factor. VA was induced by ventricular pacing in six of nine patients.

High density lipoprotein apoprotein variability in a biracial population.

High density lipoprotein (HDL) cholesterol is a sensitive index for coronary disease in affluent societies. We have measured plasma apoprotein A-I levels (the major HDL protein) in randomly selected groups of urban and rural Fijian Melanesians and Indians. Despite higher prevalence rates of coronary disease and diabetes mellitus in Indians, Indian men and women had significantly higher A-I levels than Melanesian men and women.

Prediction of sudden death by electrophysiologic studies in high risk patients surviving acute myocardial infarction.

Seventy patients surviving a myocardial infarction complicated by heart failure or arrhythmias, or both, were studied 7 to 20 days after the infarction. Twenty-four hour electrocardiographic ambulatory monitoring and intracardiac electrophysiologic studies were performed in each patient. Electrophysiologic studies included introduction of single right ventricular premature stimuli during sinus rhythm (70 patients), atrial pacing (35 patients) and ventricular pacing (70 patients) at a stimulating voltage of 2 V, with the use of higher stimulating voltages (up to 10 V), and double right ventricular premature stimuli in 33 patients and pacing at a second right ventricular site in 50 patients.

The St Jude medical valve - the Australian experience.

Since October, 1978, 181 St Jude medical cardiac valves have been implanted in 166 patients throughout Australia. There were 152 single implants, 13 combined mitral and aortic valve implants, and one triple valve implant. Hospital mortality rates were similar to those for all types of prosthetic cardiac valves.

Results of coronary artery surgery.

Four hundred and two patients undergoing coronary artery surgery from 1972 to 1978 inclusive have been followed up; 343 patients had coronary artery surgery without associated surgical procedures. In the over-all experience, the operative mortality rate was 5% falling to 1.5% in recent years.

Use of lignocaine and atropine autoinjectors for patients at high risk of sudden death and reinfarction after myocardial infarction.

Twenty-five patients entered a prospective study to assess the usefulness of atropine and lignocaine autoinjectors for coronary events after discharge from hospital after a definite, complicated myocardial infarction. They were selected on the basis of being at high risk of sudden death and reinfarction, being less than 70 years of age and being able to maintain a close liaison with the hospital. One or both autoinjectors were used for five reported events (four of collapse, one of chest pain) in four patients, with possible benefit in two instances.

Patient initiated implantable pacemakers for paroxysmal supraventricular tachycardia.

Seven patients with recurrent paroxysmal supraventricular tachycardia (PSVT) resistant to standard drug therapy were treated with patient initiated implantable pacemakers. All patients had required frequent hospital admissions and cardioversions prior to pacemaker implantation. Two patients had Wolff-Parkinson-White (WPW) syndrome on their surface ECGs and five patients had no ECG evidence of preexcitation.

Effects of quinidine and disopyramide on serum digoxin concentrations.

Although quinidine and digoxin are frequently given together, it has only recently become apparent that serum digoxin concentration may rise during quinidine treatment. A prospective study was performed to compare the effects of quinidine and disopyramide in patients receiving maintenance digoxin therapy. During quinidine administration serum digoxin concentration rose by more than 50% in seven of nine patients (the mean concentration rising from 1.

Prospective angiographic assessment of factors affecting early patency of saphenous vein-coronary artery bypass grafts.

Between November 1977 and September 1978, early post-operative angiography was performed in 50 of 53 consecutive patients undergoing coronary artery bypass surgery. An average of 2.4 grafts per patient were applied.

The refurbished pulse generator.

With the advent of long-life lithium pulse generators, normally functioning pulse generators with a potential life of more than five years have been removed from patients and become available for re-implantation. Although pulse generator refurbishing is widely employed, the practice has not been accepted in the United States. At The Royal Melbourne Hospital, all lithium pulse generators removed because of patient death or other causes were washed in a quaternary ammonium compound and soaked in formaldehyde.

Electrocardiographic findings in a partly urbanised Polynesian population. The Funafuti survey.

Electrocardiographic changes defined as probable or suspect ischaemic heart disease and coded according to the Minnesota coding system, were found in 14 (10.3 percent) of 136 Funafutians surveyed. Of these abnormal electrocardiograms, nine were classified as "probable" ischaemia and five as "suspect" ischaemia.

The small-tined pacemaker lead--absence of dislodgement.

The Medtronic 6961 unipolar transvenous ventricular lead has four symmetrically placed, small tines that protrude backward just proximal to the tip, and are designed to become entrapped beneath or between right ventricular trabeculae. One hundred leads were implanted. Initially, the leads were more difficult to position at the right ventricular apex as the tines tended to anchor on intracardiac structures.
