Resting and total energy expenditure in patients with ischemic heart disease.

Total energy expenditure (TEE) was measured by doubly labeled water in 13 preoperative patients undergoing elective coronary artery surgery and compared to resting energy expenditure (REE) measured by indirect calorimetry (IC) calculated from the Harris-Benedict (HB) formula or from formulas based on midarm circumference and arm muscle circumference. Mean REE measured by IC and calculated from the HB, midarm circumference, arm muscle circumference formulas were 62, 75, 62, and 69%, respectively, of TEE measured by doubly labeled water. REE measured by IC correlated significantly with that predicted by the HB (p = 0.006) but not the anthropometric formulas. The relationship between REE derived from anthropometric predictive formulas and REE measured by IC is altered in ischemic heart disease.     

Some new clinical applications of rhinomanometry

Clinical applications of active anterior rhinomanometry of the oscillation type had been carried out for the purposes other than the conventional uses of rhinomanometry. 1. Effect of acupuncture upon the nasal resistance to airflow: Among 8 acupuncture points which were recorded in Chinese traditional medical literatures as effective for improving nasal breathing, Ingxiang point had been proved to possess definite effect of lowering the nasal resistance to air-flow in patients with congestion of nasal mucosa, whereas in other acupuncture points this effect was not certain. 2. The severity of snoring before and after treatment could be determined objectively by the measurement of nasal resistance to air-flow and the breathing pattern of the patient.     

Deafness in juvenile relapsing polychondritis. A case report

Relapsing polychondritis is an autoimmune disease that affects all body cartilages. The disease may also involve the audio-vestibular system, usually bilaterally. Most of the reported cases were adults 20 years old or more. This is a case report of a 12-year-old girl with unilateral sensorineural hearing loss, and a review of the literature.     

Ethmoidal mucocoeles in children

Children presenting with ethmoidal mucocoeles are rare. Five children are presented with such findings, and the diagnosis, treatment and possible aetiology discussed. C.T. scanning was found to be the investigation of choice, while plain sinus X-rays correlated poorly with the presence of disease. Exenteration through an external approach was found to be satisfactory. In two cases drainage obstruction due to congenital abnormality was thought to be the underlying cause, while in four cases there was a strong history of atopy, indicating allergy as a possible reason for mucocoele formation.     

Phonological disorders in children: changes in phonological process use during treatment

Unintelligible speech in childhood is often characterised by the use of unusual or deviant (i.e. non-developmental) phonological processes, e.g. initial consonant deletion. These processes are reported to appear at speech onset and to undergo little spontaneous change during the preschool years. The study reported here documents the changes that occurred in the phonological systems of seven phonologically disordered children during remediation that targeted unusual phonological processes. Qualitative changes in phonological process use were observed for all children. Six of the children made quantitative improvement in terms of the percentage consonants produced correctly in spontaneous speech. Individual differences in phonological learning strategy use are described.     

The effect of social learning intervention on metabolic control of insulin-dependent diabetes mellitus in adolescents

This paper reports the results of an experimental study modeled after a study conducted by Kaplan et al. The hypothesis tested was: Adolescents who receive a social learning intervention (SLI) will show greater improvement in metabolic control of their diabetes than will adolescents who receive only traditional diabetes instruction. Thirty-four adolescents between the ages of 12 and 16 who attended a midwestern camp were randomly divided into two groups. Both groups attended a daily 1-hour teaching session about diabetes. Later each day, the experimental group received an SLI consisting of role modeling to help the subjects circumvent peer pressure. To determine metabolic control, HbA1 values were determined before and 3 1/2 months after the intervention. The control group showed no significant difference in HbA1 values, while the experimental group showed a decrease in metabolic control.     

Clinical features and outcome in 68 cases of aneurysmal subarachnoid hemorrhage without aneurysm repair--a community hospital study

The authors studied the clinical features and outcome at 6 months in 191 patients with subarachnoid hemorrhage (SAH) from ruptured aneurysms. Aneurysm repair (AR) was undertaken in 123 cases (64.4%). In the non-AR group (n = 68), 48.5% of the patients were 70 years of age or older, compared with 12.2% in the AR group. The duration from onset to admission was less than 3 hours in 48 non-AR cases (70.6%) and in 42 AR cases (34.1%). Among non-AR patients, 63.2% were Hunt and Hess grade IV or V, whereas the figure for AR patients was only 14.7%. By 6 months after SAH, 94.1% of non-AR patients had died, and the remainder were vegetative or severely disabled. In contrast, only 15.4% in the AR group died, and over 50% showed good recovery. The large majority of non-AR patients were treated conservatively because they were judged to be poor surgical risks and, among these patients, nearly one half were elderly. In the 10 elderly patients considered good surgical candidates, vasospasm was the most common reason (70%) for not performing AR.     

Decreased caloric intake in normal-weight patients with bulimia: comparison with female volunteers

Patients with bulimia (binge-purge syndrome) frequently complain that they consume a very restrictive diet to avoid gaining weight. To investigate this claim, 23 hospitalized bulimic patients were assessed daily for body weight, caloric intake, macronutrient diet content, activity measures, and body composition estimates during weight-stable periods. Bulimic patients ate fewer kilocalories per kilogram body weight (22.1 +/- 4.6 kcal/kg) than did age-matched normal women (29.7 +/- 6.5 kcal/kg) but had similar activity levels and body composition. Clinical variables, such as history of laxative abuse, anorexia, or obesity, and physiological characteristics, such as body weight, activity level, or dietary content, could not account for this difference in caloric consumption. Bulimic patients tended to eat a diet lower in fat and higher in protein than did control subjects. These results agree with observations of increased efficiency of caloric utilization in obese patients and support patient complaints of a tendency to gain weight easily.
