Hyperkinesis has been increasingly recognized as a medical problem of great significance in everyday practice. Not infrequently, a child has been labeled hyperkinetic at an early age, with a battery of tests, psychological evaluations and multiple medications, in addition to the family frustration and anxiety that follow the diagnosis of ...

The family physician has the unique opportunity to evaluate suicidal ideas, behavior and risk by using his demographic and medical knowledge, applying interview skills and involving the family and friends in the initial assessment. Having made an intelligent and complete assessment of the suicide threat, he can then select the ...

Pulpotomy in primary teeth using the formocresol method results in varying degrees of devitalization of the root pulp. The extent of this devitalization depends on, among other things, the ability of the components of formocresol to leave the dressing. The purpose of this study was to evaluate the rate and ...

Identification accuracy of fourteen cephalometric landmarks was compared between xeroradiographic cephalograms and conventional cephalograms. Four landmarks--point A, upper incisor tip, infradentale, and menton--were more accurately determined on the xeroradiograph, while two landmarks--point B and condylion--were more accurately determined on the conventional cephalogram. Although not conclusively demonstrated in this study, the ...

A medical audit revealed marked deficiency in the quality of functional evaluations in a rehabilitation hospital. Routine staff educational programs and an optional, simple functional evaluation form failed to correct this deficiency. The functional evaluations of the patients never reached 100% completion and the quality of the evaluations varied widely. ...

A five month study was undertaken to evaluate the role played by a clinically trained pharmacist on a polydrug detoxification unit. A total of 69 patients were included in the study. Four parameters were investigated in the evaluation. These sought to document the pharmacist's ability to: (1) evaluate degree of ...

During a 30-month period 229 couples were evaluated for infertility at the Naval Regional Medical Center, Oakland. Laparoscopy was used in all cases of otherwise unexplained infertility. The resulting laparoscopic examination of the female partner of 24 such couples demonstrated abnormal findings in 18 (75%). Of these 18 subjects, unsuspected ...

During the period 1969-1975, 12 disqualified U.S. Army helicopter aviators with various finger amputations were evaluated by the U.S. Army Aeromedical Consultation Service for return to flying duties. The evaluations included both medical examinations and in-flight performance observed by aviation medicine specialists and standardization instructor pilots. The criteria for aeromedical ...

The literature of continuing medical education (CME) program evaluation was reviewed and analyzed. The "State-of-the-art" of CME evaluation is depicted in a series of tables which indicate evaluation methods and results. Evaluation designs providing strong assurances of valid results were not often found. The weakness of most published evaluations limit ...

The advent of nuclear cardiology has resulted in a veritable explosion of new techniques for evaluating coronary artery disease. Most of these new techniques for detecting myocardial performance, myocardial perfusion patterns, shunt detection, and infarct detection can be done in sequential noninvasive fashion so that patient may be selected earlier ...

A new cholangiography catheter has been evaluated in 66 consecutive gall bladder operations. The catheter has an integral moulded cone shaped locking attachment and a tap to reduce the risk of air bubbles entering the biliary tree. The catheter coulc not be introduced into the duct in 10% of patients. ...

This paper is a review of the theory and practice of disability evaluation with emphasis on the distinction between medical impairment and disability. The requirements for making an accurate assessment of medical impairments are discussed. The author suggests three basic standards which can be used for establishing a simplified method ...

The medical work-ups received by hypertensive patients at Charity Hospital, New Orleans, during a three-month period in 1972 were evaluated. One hundred charts were reviewed using a questionnaire which covered aspects of history, physical examination, and laboratory tests important to the clinical evaluation of hypertension. The frequency with which these ...

Cholecystokinin-cholecystography originated in Stockholm in 1955. At the present time the radiological procedure is conducted under supervision of medical research teams in the United States. The cholecystokininpancreozymin preparation is imported for clinical investigation under "Investigational Drug" regulations. Dr. Donald Hanscom, gastroenterologist, who is conducting clinical investigations in the Midwest, submitted ...

The results of an in vivo evaluation of silver sulfadiazine dry foam are described. Using burned guinea pigs infected with Pseudomonas aeruginosa, silver sulfadiazine was applied every 12hr as the dry foam or ointment. After 72 hr of therapy with the medicated dry foam, only one of the 15 burns ...

In male pseudohermaphrodites born with ambiguity of the external genitalia but with marked virilization at puberty, biochemical evaluation reveals a marked decrease in plasma dihydrotestosterone secondary to a decrease in steroid 5alpha-reductase activity. In utero the decrease in dihydrotestosterone results in incomplete masculinization of the external genitalia. Inheritance is autosomal ...

Xanthomatous infiltration of tendons is a clinical feature common to many cases of hyperlipidemia. The xanthomas can be detected and only grossly assessed by palpation.
