Long-term diabetes and hypertension can lead to changes in cardiac contractility, reduced left ventricular efficiency and heart failure. The aim of this study is to evaluate the effect of the coexistence of diabetes mellitus and hypertension on left ventricular myocardial performance and structural changes. The study involved 45 patients with essential hypertension and type 2 diabetes (14 males and 31 females, their mean age was 53.28 ± 13.28 years), and 45 healthy subjects (10 males and 35 females, their mean age was 48.11 ± 13.07 years) as a control group. Transthoracic echocardiography was done for all patients. The echocardiographic measurements included: left ventricle internal diameter at end diastole (LVIDd), left ventricle internal diameter at end systole (LVIDs), peak velocity of early transmitral flow (E), peak velocity of late transmitral flow (A), ejection fraction (EF%), isovolumic relaxation time (IVRT), isovolumic contraction time (IVCT) and ejection time (ET) from which the index of myocardial performance (IMP) was calculated. Results revealed a significant change in the ratio (E/A) between patients and controls (-32.45%) with p value p value 0.05. In conclusion, diabetic patients with hypertension had an increase in IMP and reduced E/A indicating deterioration in cardiac performance despite normal ejection fraction and insignificant change in LV dimensions.展开更多

A total of 26 have completed three months’ treatment, aged 16 - 50 years. Patients were treated by diode laser 808 nm and IPL 690 - 1200 nm devices. Pulse repetition rate for both was 1 Hz and short pulse width for diode laser and the IPL pulse width was 15 ms. The fluence was (33 - 41 and 30 - 41) J/cm2 respectively. A split face treatment method was used. The treatment was carried out on monthly bases for three months. Hair density and regrowth duration were recorded before and after each session. After the third session, the hair density was decreased by (58%) for diode laser versus (49%) for IPL p = 0.366. The time of hair regrowth was increased to (327%) for diode laser versus IPL (339%) p = 0.821. Pain appeared more during the treatment with IPL than with diode laser. Post treatment side effects such as erythema, hyper pigmentation, and burn appeared on patients treated with diode laser more than those treated with IPL. In conclusion both diode laser and IPL were effective in reduction of hair density, and prolongation of the time of hair regrowth.展开更多
