For the non-invasive evaluation of cardiac performance in hyperthyroidism, fractional systolic and diastolic time intervals were determined in 96 female patients with hyperthyroidism from the mechanocardiograms which included apexcardiograms together with electrocardiograms, phonocardiograms and carotid arterial pulse tracings. The observed values of the time intervals inversely related to heart rate, i.e., ejection period, mechanical systole, isovolumic relaxation time and active ventricular filling period, were significantly shortened in proportion to the severity of the disease in general, as determined by the rate of the radioactive iodine uptake of the thyroid glands. However, these values were not significantly different from those of the predicted for heart rate, except for one of mechanical systoles which is a time interval from the onset of the systolic upstroke in the apexcardiogram to the second aortic sound. This suggests that the shortening of these observed values is promarily due to tachycardia associated with hyperthyroidism. One the other hand, the observed values of the time intervals unrelated to heart rate, i.e., electromechanical delay, isovolumic contraction time together with one of its components, namely ventricular pressure elevation time, and rapid ventricular filling period, were significantly shorter than those in the controls, although the degree of the shortening was not related to the degree of the radioactive iodine uptake of the thyroid gland. It appears that the shortening of these time intervals is related to the altered cardiac function caused by hyperthyroidism and, in particular, that of the isovolumic contraction time and ventricular pressure elevation time reflects enhancemet by the thyrotoxic myocardial contractility.

PURPOSE: Infrared thermometers are increasingly used as a convenient, non-invasive assessment method for febrile children. However, the diagnostic accuracy of the infrared thermometer for children has been questioned, particularly in relation to sensitivity and specificity. The aim of this study was to evaluate diagnostic accuracy of infrared thermometers in febrile children. METHODS: Articles published between 1966 and 2012 from periodicals indexed in the Ovid Medline, Embase, CINAHL, Cochrane, KoreaMed, NDSL, KERIS and other databases were selected, using the following keywords: 'infrared thermometer'. The QUADAS-II was applied to assess the internal validity of the diagnostic studies. Selected studies were analyzed using meta-analysis with MetaDisc 1.4. RESULTS: Nineteen diagnostic studies with high methodological quality, involving 4,304 children, were included. The results of meta-analysis showed that the pooled sensitivity, specificity and AUC (Area Under the Curve) of infrared tympanic thermometers in children over 1 year were 0.80 (95% CI 0.78, 0.81), 0.94 (95% CI 0.93, 0.95) and 0.95 respectively. However the diagnostic accuracy of infrared tympanic thermometers in children with hyperthermia was low. CONCLUSION: The diagnostic accuracy of infrared tympanic thermometer was similar to axillary and rectal thermometers indicating a need for further research to substantiate these findings in children with hyperthermia.

Antianginal and untoward effects of fenalcomine hydrochloride were studied in 24 cases of angina pectoris. Following discontinuation of all medications for 2 weeks except for liberal use of sublingual nitroglycerin for the relief of anginal attack, fenalcomine, 150mg a day in 3 divided doses, was given for 8 to 16 weeks. In 20 cases, routine blood counts including platelets, serum electrolytes and cholesterol as well as blood sugar level were checked before and at the completion of the medication. hepatic and renal functions were also studied. The effect of fenalcomine on severity, frequency and duration of anginal attack was excellent to good in 17 cases(70.9%), and was fair in 5 cases(20.8%). In the remaining 2 cases(8.3%), who responded poorly had angina pectoris for more than 3 years. It appeared that fenalcomine was similarly effective in those with or without associated hypertension or diabetes mellitus, or history of previous myocardial infarction. The comparison of the results of post-treatment laboratory tests with pre-treatment data revealed no significant changes. Furthermore, no untoward clinical reactions attributable to the drug was noted in all cases. These facts suggest that fenalcomine is a reliable and well tolerated antianginal agent which can be used singly or in combination with other agents.

Effects of thoracentesis on thoracic impedance and cardiac performance were studied in patients with uncomplicated unilateral tuberculous pleural effusion. The speed of the removal of the pleural effusion in thoracentesis was essentially similar to that of a generally used for therapeutic purpose in daily practice. Thoracic impedance was measured in 23 cases before, 4 and 10 minutes after thoracentesis to the amount of pleural effusion aspirated was observed. In 11 cases out of 23, the changes in cardiac performance as assessed by stroke volume, cardiac output, heart rate, heather index and ratio of pre-ejection period to left ventricular ejection time(PEP/LVET) were observed 4 minutes after 150 ml to 1,000 ml of thoracentesis. In these cases, stroke volume, cardiac output, and Heather index were determined from impedance cardiograms, and PEP/LVET from mechanocardiograms recorded simultaneously with the former. A significant increase in thoracic impedance was observed both 4 and 10 minutes after thoracentesis. There was a slight but a significant correlation between the changes in thoracic impedance and the amount of pleural fluid aspirated only 4 minutes after thoracentesis. Thoracentesis showed no consistent influence on cardiac performance as reflected to stroke volume, cardiac output, heart rate, heart index and PEP/LVET. These facts suggest that measurement of thoracic impedance may be a useful method reflecting alterations in pleural fluid volumes, particularly when it occurs in a relatively short period of time, and the effects of thoracentesis of less than one liter on the cardiac functions as determined by the above-mentioned parameters were variable.
