BACKGROUND: Decreased heart rate variability(HRV) has been shown to be an independent predictor of poor outcome after acute myocardial infarction, Spectral analysis of HRV has recently been shown to be a reliable noninvasive test for quantiative assessment of cardiovascular autonomic regulatory response. We estimated the reproducibility and circadian rhythm of HRV parameters in patients with acute myocardial infarction. METHODS: Three consecutive 24-hour ambulatory electrocardiographic recordings were made in 24 patients with acute myocardial infarction, with 10~14 days after the acute attack, and analyzed for HRV parameters of both frequency and time domains. Parameters of frequency domain include low frequency(LF) and high frequency(HF) components. Parameters of time domain include sdRR, SDANN, SD, pNN50, rMSSD, HRV index. RESULTS: Mean total, low frequency and high frequency amplitude spectral densities were 33msec, 19msec and 11msec, respectively. Mean values of sdRR, SDANN, SD, rMSSD, pNN50 and HRV index were 103msec, 90msec, 47msec, 28msec, 7% and 32, respectively. Coefficients of variation(CV) of total amplitude spectral density, and low and high frequency components were 7%, 9% and 12%, respectively. CV of most HRV parameters of time domain were also around 10% except rMSSD and pNN50. Heart rate increased in the morning to be sustained during the day time and decreased in the night. Heart rate variability of high frequency component decreased in the early morning to be sustained during day time with increase in the night. CONCLUSIONS: We conclude that in the predischarge period of acute myocardial infarction, HRV parameters of frequency and time domains are reproducible and there are some morning fall of cardiac vagal activity.

Spondylometaphyseal dysplasia (SMD) is an extremely rare, which affects the spine and metaphy-ses of the tubular bones on terms of enchondrogenesis. Children who had Kozlowski dwarfism, type of SMD are not recognized until they reach school age since they have normal clinical feature, weight and size in early childhood. Authors experienced a typical case of Kozlowski type of SMD in a 10 years old male who had i) generalized platyspondyly with anterior tapering of vertebrae ii) generalized metaphyseal dysplasia iii) minimal changes in the carpal and tarsal bones. This case is to be reported with review of references.

BACKGROUND: The SF-6D, derived from the SF-36, is a preference-based instrument measuring health-related quality of life (HRQOL). Using this tool, we measured the HRQOL of persons disabled by stroke dwelling in Gyeongju city and identified factors affecting the HRQOL. METHODS: As of March 2008, 991 persons who had had a stroke and were aged 50 and over were identified on the Gyeongju city disabled registry. Interviewers specifically trained for this face-to-face survey gathered pertinent information including general and clinical characteristics from June to October 2008. In addition, the health status was measured using the Modified Rankin Scale, the Barthel ADL index, and the SF-36. The SF-6D index was derived from the SF-36. We analyzed the known-group construct validity and convergent validity. Finally, we performed multiple regression analyses to identify factors affecting the HRQOL. RESULTS: Of the 991 potential subjects, 498 persons participated in the interviews (response rate: 50.3%). The SF-6D indices for females and those aged 70 and over were lower than indices for males and those aged 60 and less. Correlation coefficients between the Modified Rankin Scale, the Barthel index, and the SF-6D index were relatively high (-0.533 and 0.555, respectively) and statistically significant (P<0.001). Multiple regression analyses showed that sex, age, smoking, alcohol use, comorbidity, the Modified Rankin Scale, and the Barthel index had an effect on the SF-6D index of persons with stroke, and the Barthel index was the most important factor. CONCLUSIONS: Our results indicate that the SF-6D can be a valid tool for evaluating health states of persons disabled by stroke, and functional limitation was the main factor affecting the HRQOL.

From May 1, 1993 to May 31 1995, the authers studied retrospectively 211 patients who underwent cardiovascular operation with cardiopulmonary bypass (CPB). Because we were interested in new development of ARF (prevalence, mortality rate, and main risk factors), we performed a multivariate statistical analysis about data of patients with preoperative serum creatinine values of less than 1.5 mg/dL. Normal renal function before operation (serum creatinine level less than 1.5 mg/dL) was registered in 198 (74%) patients. Of these, 27 (14%) patients showed postoperative renal complication, including 20 (10%) patients classified as renal dysfunction (serum creatinine level between 1.5 and 2.5 mg/dL) and 7 (4%) patients as acute renal failure (serum creatinine level higher than 2.5 mg/dL). The mortality rate was 5.8% in normal patients, 5% in patients with renal dysfunction, and 43% when acute renal failure developed (p=0.036). Indeed, the renal impairment proved to be an independent predictor of mortality (odd ratio 2.52~11.25), along with cardiovascular (odd ratio 4.20) and respiratory (odd ratio 2.18) complications. Multivariate analysis identified the following variables as independent risk factors for postoperative renal impairment : advanced age (odd ratio 1), need for emergency operation (odd ratio 3.78), low-output syndrome (odd ratio 3.66), respiratory complication (odd ratio 1.30), need for deep hypothermic circulatory arrest (odd ratio 1.4). The 13 patients (7%) with preoperative renal failure showed a significantly higher morbidity and mortality rate than those without renal complications before operation. We concluded that the likelihood of severe renal complications is resonably low in the patients undergoing cardiac operation without preexisting renal dysfunction, but associated mortality remains high. A prominant role of hemodynamic factor in the development of postoperative acute renal failure must be recognized during preoperative, intraoperative, and postoperative periods.

A 56-year old female underwent total aortic arch replacement March 1995, because of an expanding chronic Debakey type I aortic dissection. This aortic dissection had an intimal tear at the origin of the right carotid artery. Retrograde and antegrade propagation of dissection resulted in aortic arch blood flow separation and expanding pseudolumen to the abdominal aorta. Sudden anuria (ARF) developed 3 hours later postoperatively and renal doppler ultrasonography and aortography showed diminished blood flow of renal arteries. We performed balloon aortic dilatation but failed. She could be restored good renal flow after intimal flap fenestration resection and thrombectomy of the abdominal aorta. This patient could be discharged in a state of mild CRF after 2 months of ICU care for respiratory and renal failure.

BACKGROUND: Quyyumi et al described circadian variation of ischemic eletrocardio-graphic changes and heart rate in patients with and without significant coronary disease in 1985. Rocco et al also described circadian variation of transient myocaldial ischemia in patients with coronary artery disease. They also noted an increse in ischemic eletrocardiographic abnormalities in the morning hours.In recent years the important of circadian variation of cardiovascular phenomena has generated a great deal of interest. Such phonomena include the occurrence of ischemia in patients with both chronic stable angina and variant angina, myocaldial infarction, sudden cardiac death, ventricular arrhythmia and platelet aggregability. METHOD: To examine whether a significant circadain variation of transient myocardial ischemia exists and to better understand the character of such variation, 35 patients with againa pectoris(15 patients treated with nitrate and/or caclcum channel blocker and 20 patients without treatment) underwent 24 hours ambulatory monitoring of ischemic ST segment changes during daily life. RESULT: Only 21% of the episodes of ST depression were accompanied by chest pain. While 79% were asymptomatic. A significant circadian increase in ischemic activity was found with 44% of episodes and 40% of total ischemic time in not treated group, and 52% of episodes and 56% of total ischemic time in treated group, occuring between 6 A.M. to 12 P.M.(P<0.05 respectively) When the distribution of ischemic episodes was corrected for the variable time of waking, the peak ischemic activity was occuring in the 1st and 2nd hours after rising. There were no significant differences in heart rate at onset and heart rate at 1 min before onset. CONCLUSION: Is summary, transient myocardial ischemia in the absence of pain was more common and there were a significant circadian variation of transient myocardial ischemia with peak activity in the morning. In addition most of transient myocardial were not preceded by a rise in heart rate.

Patient management is considered an important factor in dental field. The aim of this review is to analyze the efficacy of hypnosis to treat fear, anxiety, pain, stress of dental patients, and see how it can be adopted in dentistry for improving patient satisfaction. Medline research was carried out to find the use of hypnosis in dentistry and other aspects of hypnosis in medical area. It can help patient more comfortable, relax, and accordingly reduce patient's negative feelings such as fear, anxiety, pain, stress during dental treatment. Also, it affects patient recovery after surgery by accelerating healing speed and reinforce immune system. When hypnosis is used with other anesthetic method, it can reduce the use of main medication, leading to reduce possibility of side effect. Therefore, using Hypnosis can give patients more comfortable dental experience, both mentally and physically, ultimately making patients more satisfied with the dental treatment.
