Pigmentary dermarcation lines are boundaries between more deeply pigmented skin and areas of lighter pigmentation. We report 4 cases of pigmentary demarcation lines of pregnancy associated with erythema which developed in the third trimester of pregnancy and were symmetrically located in the buttock and posteromedial portion of the lower extremities. After delivery, the erythema disappeared within 3-7 days, followed by slow resolution of the brownish pigmentation.

Orthofix, a unilateral external fixator is simple and easy to use and it's design is also convenient to reduce and maintain the fracture site. In addition, wide range of application is an another advantage because compression and distraction is possible in the central body. Authors reviewed 56 operations in 50 patients for whom Orthofix was applied for 4 years from march 1988 to february 1992 in Chonnam University Hospital. There were 46 males and 4 females. Twenty five patients(50%) were between 20 to 40 years of age. The indication was open fracture of the long bone in 27 cases, infected nonunion in 17 cases, bony defect in 4 cases, arthrodiastasis in 3 cases, arthrodesis in 2 cases and others in 3 cases. 1. There were 23 cases treated with Orthofix only until completion of treatment, 17 cases necessary to another methods of treatment, 14 cases maintaining Orthofix until now and 2 cases miscellaneous. 2. The duration of maintenance of Orthofix until completion of treatment in 20 cases of open fracture of long bone or infected nonunion was 9.5 months in average. 3. The bone union time averaged 9.5 months in above 20 cases and there was a little difference of bone union time between open fractures and infected nonunions. 4. Result of long term follow-up in 20 cases open fracture of long bone or infected are as follows; 12 cases(60%) have angulation less than 10° or length inequality less than 10mm, 14 cases(70%) have showed no limitation in range of motion or mild limitation of joint above and below the fracture site. 5. Complications, directly related to Orthofix, developed in 17 cases. There were 15 cases of pin tract infection and 2 cases of fixation loosening. Orthofix was considered as one of the excellent external fixation system, for it is simple and easy to use and could provide rigid fixation for difficult conditions in Orthopedic field such as open fracture, infected nonunion, bony defect and arthrodiatasis.

We report a case of epidermal nevus syndrome showing various skin manifestations improved with CO₂ laser and chemical peeling in a 11-year-old girl. Skin lesions were composed of linear verrucous plaques and numerous papillomatous papules on the face, neck, scalp and trunk, multiple congenital nevocellular nevi on the face, and extensive cafe au lait spots on the trunk. The associated findings of skeletal involvement were gingival hemihypertrophy and benign bone lesion of the 7th rib. CO₂ laser and chemical peeling MCA, 50% TCA) were applied to remove these skin lesions which improved considerably.

9.Association of Occupational Stress and Cardiorespiratory Fitness with Cardiovascular Disease Risk Factors in Office Workers.
The Korean Journal of Sports Medicine 2017;35(1):48-56
Occupational stress is associated with increased risk of cardiovascular disease (CVD), while cardiorespiratory fitness (CRF) is associated with decreased risk of CVD. We tested the hypothesis that high occupational stress would be associated with increased cardiovascular risk profiles, but CRF may attenuate this association. We conducted a cross-sectional analysis in 70 healthy office workers (male, 28; female, 42; mean age, 38±8 years). Occupational stress was assessed using a validated self-reported questionnaire. Total CVD risk score (sum of z-standardized residuals) was calculated by blood pressure, body mass index, lipid profiles and glucose. CRF was estimated by predicted equation during maximal treadmill exercise test. The results showed that an interpersonal conflict as an index of occupational stress was positively correlated with cardiovascular risk score (r=0.43, p<0.05). In contrast, Higher CRF was associated with lower occupational climate (r=−0.25, p<0.05) and total occupational stress score (r=−0.29, p<0.05). The total CVD risk score was similar between group with high stress but high fitness and group with low stress and high fitness (p>0.05). Furthermore, Participants with high stress but high CRF had lower cardiovascular risk score than those with high stress but low CRF (p<0.05). In conclusion, occupational stress is associated with an increased CVD risk, but CRF attenuated this association in office worker with increased occupational stress.

Cardiovascular changes induced by a variety of physiological, surgical or emotional stresses are associated with increased sympathetic nervous system activtity. Sympathetic stimulation lowers the ventricular resistance in patients with ischemic heart disease. Thus sympathoadrenal aetivation may play role in sudden cardiac death. We measured the catecholamine levels just before and after fiberoptic gastroscopy, The results were as follows: 1) Though there was no statistical significance, plama catecholamine levels tends to increase during and after fiberoptic gastroscopy. 2) Significant changes in mean blood pressure did not occur during and after fiberoptic gastroscopy. 3) Before fiberoptic gastroscopy, norepinephrine level of three hypertensive patients were lower than the levels of studied patients, But during and after fiberoptic gastroacopy, norepinephrine level increased by 3 times. 4) The highest norepinephrine level was 847 pg/ml and epinephrine level was 110 pg/ml. Though sympathetic response was enhanced by fiberoptic gastroscopy, norepinephrine level did not increase up to the level shown in myocardial infarction or severe exercise.
