Recent studies have indicated a rising prevalence of hypertension in rural and urban areas of India. A population-based survey was carried out during 1994 -1995 in seven rural and non-industrialised villages around RaipurRani block in the state of Haryana, India, to determine the prevalence of hypertension and its associated risk factors. A total of 2559 individuals (86% of the eligible population) in the 16 to 70-year age group were interviewed using a pre-tested structured questionnaire to find out the lifestyle characteristics. Three blood pressure (BP) readings were recorded with a random zero sphygmomanometer at three different times. One hundred and fourteen individuals (4.5%) were found to be hypertensive according to JNC V criteria (BP of у 140/90 mm Hg). Mean systolic and diastolic BPs were 116.9 and 71.7 mm Hg in males and 119.1 and 72.7

Blood pressure was determined among 2,453 schoolchildren aged between 7 and 16 years in the northwest Indian town of Chandigarh to establish the norms. The percentiles were calculated for each age group in both sexes. Both systolic and diastolic blood pressure had a positive correlation with age, weight, height, and body surface area (r = 0.112-0.178, p less than 0.01). There was no difference in the systolic and diastolic pressures of boys compared with girls of corresponding age. The upper limits of normal (90th percentile) systolic/diastolic pressure were 113/74, 119/76, and 126/79 in children aged 7-9 years, children aged 10-12 years, and adolescents aged 13-16 years, respectively. The lower limits of hypertension (95th percentile) for systolic/diastolic pressure were 119/80, 124/81, and 132/82 in each of these groups, respectively. The 99th percentile values indicative of severe hypertension for systolic/diastolic pressure in these groups were 128/88, 135/88, and 149/89, respectively. The 90th percentile of height and weight shown in the percentile table should be taken into consideration whenever blood pressure exceeds the 90th percentile for age and sex while planning the management of an individual.

Shallow-ablation of endometrial lining using microwaves has been traditionally indicated as a minimally invasive treatment option for dysfunctional uterine bleeding (DUB). Known as microwave endometrial ablation (MEA), relevant procedure is used as an alternative to hysterectomy considering its safety, simplicity and effectiveness. In lieu of the prevailing MEA techniques, it is attempted in this study to foresee the possibility of conceiving an alternative and a newer option on endometrial ablation using mm-wave/THz frequencies. Commensurate with this motivated impetus, objectively considered are merits and design issues of using electromagnetic (EM) spectrum of mm-wave/THz region toward optimal conversion of EM energy into a thermal ablative source so that, the basal layer of endometrium can be effectively destroyed in surgical contexts as necessary. Hence, the feasibility of designing appropriate TEA applicators for controlled and safe procedures so as to ablate just the unwanted tissues within a localized zone of energy field is addressed. Lastly, a quantitative analysis on the interaction of THz EM-energy versus the lossy dielectric characteristics of endometrial medium is indicated to model the underlying (THz-energy)-to-(thermal energy) transduction. Relevant prospects of conceiving TEA and the associated pros and cons are identified specific to the prospects of feasibility, requirement considerations and technical challenges.
