This study was aimed to elucidate the relationship between combinations of treadmill speed-grade and oxygen consumption(Vo2). Twenty athetic and 20 non-athletic male college students aged 19-24yr were employed to exercise on a treadmill using 4 speeds(4.02, 5.47, 6.76 and 8.05km/h) and 5 grades(0, 8, 12, 16 and 20%). A fixed speed was selected for each session with the grade increased every 3 min. The Vo2, heart rate, stride frequency and stride length were measured during the last min of each 3-min stage. Vo2increased linearly with increasing speed and grade showing significant multiple correlations in nonathletes(Vo2=3.64x+0.831y+0.031xy-7.03, R=0.98, P<0.01) and athletes(Vo2=3.48x+0.324y+0.112xy-5.74, R=0.99, P<0.01). Stride frequency and length tended to increase with increasing speed except for the transition from walking to runnig at 8.05Km/h at which the stride frequency ran up much higher with the stride length getting lower than at 6.76Km/h. Heart rate increased linearly with increasing Vo2. The rate of increase was higher during walking than during running. These results indicate that athletes have higher rate of increase in Vo2than nonathletes at near-maximal exercise and may be used as a guideline in predicting maximum oxygen comsumption and in prescribing exercise intensity.

Erythema multiforme is an episodic, self-limited, mucocutaneous, inflammatory disorder and the disease manifests as severe form is called Stevens-Johnson syndrome. It is most commonly precipitated by herpes simplex infection or drugs and the pathogenesis of the mucocutaneous lesion is thought to be related to immune complexes, cell-mediated immunity, or both. We experienced a case of Stevens-Johnson syndrome in 23-year-old female who had systemic bullous kin lesion and diffue mucopurulent conjunctivitis after use of oral acetazolamide for control of steroid-induced increased intraocular pressure after excimer laser photorefractive keratectomy, which has not been reported in Korea. So, we report this case with a review of the literature.

We performed 15 cases of modified Bristow procedures for recurrent anterior instability of shoulder from january, 1987 to december, 1992 and the following results were obtained. 1. The patient's age at initial dislocation varied from 15 years to 29 years of age. 2. The most common cause of the recurrent anterior instability of shoulder was sport injury(6 cases) and next were traffic accident, hanging with one hand. 3. The average loss of external rotation of shoulder after operation were 10 degrees and internal rotation were 7 degrees. 4. The post-operative complication and recurrence were not observed. 5. End results were excellent in 7 and good in 5 by Rowe's grading system. 6. Strict attention to bone block placement was mandatory and decreased the risk of screw malpo-sition.

Premature peripheral arterial disease is characterized by onset of peripheral arterial occlusion before age of 50 years. Its prevalence is rare. To the best of the authors’ knowledge, there is rare research of premature peripheral arterial disease in Korea. The authors encountered a case of necrotic toe caused by premature peripheral arterial disease after soccer workout. This paper reports this case with a review of the relevant literature.

PURPOSE: The purpose of this study was to investigate the experience of uncertainty in cancer patients undergoing chemotherapy in South Korea. METHODS: Data were obtained from in-depth interviews with ten cancer patients conducted from Mar. 21 to Nov. 11, 2017. The data were collected until saturation and analyzed via Colazzi's phenomenological method. RESULTS: In this study, 6 categories were extracted: Four categories contributed to uncertainty including ‘Confusion about cancer and course of treatment’, ‘Inner conflicts’, ‘Being overwhelmed by treatment’, and ‘Unknown future’. Two categories facilitated coping with uncertainty including ‘Seeking knowledge’ and ‘Need for spiritual peace’. CONCLUSION: Uncertainty experiences for cancer patients undergoing chemotherapy in different societies is largely similar. However, some experiences seemed unique to Korean patients. Also, there is a great deal of uncertainty about the treatment outcomes and loss of treatment opportunities in cancer patients undergoing chemotherapy. The results of this study will help oncology professionals develop patient-centered psychological interventions by improving understanding of the uncertainty of cancer patients undergoing chemotherapy.

Pain is often associated with a more rapid progression of cognitive and functional decline, and behavioral disturbance in dementia. Therefore, it is essential to accurately assesses pain for proper intervention in patients with dementia. The Face, Legs, Activity, Cry, and Consolability (FLACC) scale is an excellent behaviour scale which includes most of the domains that are recommended by the American Geriatrics Society to evaluate when assessing pain in patients with dementia. The purpose of this study was to develop the Korean version of the FLACC (K-FLACC) and to verify its reliability and validity in assessing pain of elderly patients with dementia. We developed the K-FLACC to consist of the five domains (face, legs, activity, cry, and consolability) with scores of 0, 1, and 2 for each domain and a total score ranging from 0 to 10 as in the original FLACC. Eighty-eight patients with dementia who visited Konkuk University Medical Center were evaluated. The K-FLACC revealed good validity as compared to the Numeric Rating Scale (NRS; r = 0.617, P < 0.001) and the Face Pain Scale (FPS; r = 0.350, P = 0.001). All of the five domains of the K-FLACC were related to the NRS and FPS, in which the activity domain showed the highest correlation. Test-retest reliability was excellent, as the intra-class correlation coefficient comparing the retest to test was 0.73 (95% confidence interval, 0.59–0.82). Our results show that the K-FLACC is a suitable and valuable scale to assess pain in patients with dementia in Korea.

Patients undergoing monocular excimer laser photorefractive keratectomy (PRK) for myopic correction can develop strabismus secondary to decompensated heterophorias. We experienced a case of ocular esodeviation and diplopia that developed 8 nionths after monocular excimer laser phtorefractive keratectomy. So, we report this case with 8 review of the literature.

PURPOSE: Wernicke's syndrome, which is characterized by nystagmus, abducent and conjugate gaze palsies, ataxia, mental confusion, and amnesia, is caused by a deficiency in levels of thiamine and is observed mainly in persons who abuse alcohol. Recognized predisposing conditions other than alcoholism include chronic dietary deprivation(imbalanced diet, prolonged intravenous feeding.) and impaired absorption or intake of dietary nutrients. METHODS: We have experienced a 31-year-old female presented 15 weeks into pregnancy who complained of icteric skin color, diplopia, and gait disturbance after prolonged vomiting for 2 months. Neurologic examination demonstrated obtunded sensations, nystagmus and ataxia of gait. EEG showed a mild degree of slowly diffuse activity. The neurological signs pointed to a diagnosis of Wernicke's encephalopathy. RESULTS: We report a case of Wernicke's syndrome induced by hyperemesis gravidarum with the review of literature.

Hepatic osteodystrophy is frequent complication in patients with chronic liver disease, particularly with chronic cholestasis. We report a male infant with congenital hepatoblastoma, who had osteodystrophy complicated by multiple bone fractures despite adequate supplementation of fat-soluble vitamins including vitamin D. He was born by Caesarean section because of a 7 cm–sized abdominal mass detected by prenatal ultrasonography. The pathologic diagnosis was hepatoblastoma, PRETEXT staging III or IV. Whole body bone scan at the time of diagnosis showed no abnormal uptake. Oral vitamin D3 of 2,000 IU/day was administered with other fat-soluble vitamins. Serum direct bilirubin level gradually increased up to 28.9 mg/dL at postnatal 6 days and was above 5 mg/dL until 110 days of age. Bony changes consistent with rickets became apparent in left proximal humerus since 48 days of age, and multiple bone fractures developed thereafter. With resolving cholestasis by chemotherapy, his bony lesions improved gradually after add-on treatment of bisphosphonate and parenteral administration of vitamin D with calcium. High level of suspicion and prevention of osteodystrophy is needed in patients with hepatoblastoma, especially when cholestasis persists.
