With the development of body sensor technology, wearable health monitoring systems have been an emerging information technology in the 'ubiquitous health care' system. Wearable sensors enable long-term continuous physiological monitoring important in health promotion and management of many chronic disorders. In this paper, we present several wearable health monitoring systems developed by different countries and discuss emerging opportunities, as well as, existing challenges such as standardization, administration, validation, and discrepancy issues between technology and clinical implication.

Hemorrhagic cystitis is potentially life-threatening sequellae of chemotherapy using oxazaphosphorine alkylating agents (cyclophosphamide and ifosfamide). Mesna contains a sulfhydryl group that is believed to bind acrolein within the urinary collecting system and reduce the hemorrhagic cystitis without affecting the chemotherapeutic potential. To date, about thirty cases of hypersensitivity or allergic reactions of the delayed and urticarial type associated with mesna have been reported. We reported two patients with systemic lupus erythematosus who developed facial rash and flushing associated with mesna which imitate malar rash.

OBJECTIVE: Whether exposure to chronic noise induces an increase in blood pressure, or the development of hypertension, has not been established. A cohort study was performed to identify the effects of chronic noise exposure on blood pressure. METHODS: 530 males working at a metal manufacturing factory in Busan, Korea were enrolled for the study. They were monitored for 9 consecutive years, from 1991 to 1999, with an annual health check-up. The subjects were divided into 4 groups, which were determines by noise level categories(NLC) according to noise intensity ; NLC-I: office workers, exposed to noise a level below 60dB(A); NLC-II: field technical supporters or supervisors, frequently exposed to workplace noise, wearing no hearing protection device; NLC-III: workers, exposed to workplace noise below 85 dB(A), wearing ear plugs or muffs; NLC-IV: workers, exposed to workplace noise over 85 dB(A), wearing both ear plugs and muffs. RESULTS: After controlling possible confoundens, such as baseline age, smoking, alcohol intake, exercise, family history of hypertension, systolic(SBP) or diastolic blood pressure(DBP) and changes in BMI (body mass index), the pooled mean for the systolic blood pressures, over the duration of the study period, were 3.8mmHg, 2.0mmHg and 1.7mmHg higher in NLC-IV, NLC-III NLC-II groups, respectively, than in the NLC-I group. There were no significant differences in the diastolic blood pressures between the groups. CONCLUSION: This study suggests that chronic noise exposure increases systolic blood pressure independently, among male workers.

Lead has been widely used in industry and contained in various household products. However, allergic reaction to lead is known to be extremely rare. A 23-year-old woman who had been working in an electronics company for 1 year presented with pruritic erythematous macules and papules on both arms and hands of 1 month duration. She was diagnosed as a contact dermatitis due to lead by patch test using lead nitrite(0.01% aq.). The cutaneous eruption subsided with treatment and has not recurred by changing the working place for 6 months. We report a case of contact dermatitis due to lead.
