It has been shown that both rest and stress myocardial perfusion imagings with technetium agents can be performed on the same day using two different doses injected within few hours. The purpose of this study was to compare the two protocols (stress-rest and rest-stress) in detecting coronary artery diseases. One hundred and sixty patients (101 males, 59 females, mean age 57+/-9 years) and 120 patients (79 males, 41 females, mean age 59+/-10 years) underwent stress-rest myocardial perfusion SPECT and rest-stress myocardial perfusion SPECT, respectively All of them underwent both myocardial perfusion SPECT and coronary angiography within 1 month. A coronary stenosis was considered significant when it compromised the luminal diameter by> or =50%. The chi square test was used to compare differences in sensitivity, specificity and accuracy between the two groups. The overall sensitivity, specificity and accuracy of stress-rest protocol were 99%, 35%and 68%, respectively. Those of rest-stress protocol were 96%, 47%, and 78%, respectively. There was no difference between the two protocols in identifying individual diseased coronary artery branches. Therefore, one day stress-rest and rest-stress myocardial SPECT using Tc-99m agents were comparable and were very sensitive tests in detecting coronary artery diseases.

6.Diapers and Infant Skin Health.
Korean Journal of Child Health Nursing 1999;5(3):241-249
Diaper dermatitis, or commonly called "diaper rash", is among the most prevalent cutaneous disorders of infancy and early childhood and important issue in nursing. The term itself is not diagnostic since it encompasses a variety of acute inflammatory reactions which are best regarded as a family of disorders arising from a combination of factors specifically attributable to the use of diapers. Intensive study of the rash process has shown that skin wetness and fecal enzyme activity are damaging to skin and lead to the development of diaper rash. This suggests that it is important to keep urine away from babies' skin, so that the skin remains as dry as possible and maintains its barrier function abilities. Controlling the urine will also minimize the mixing of urine and feces within the diaper, which helps prevent the increased activity of enzymes that attack the skin and cause irritation. Therefore, a diaper that keeps the skin drier and limits the mixing of urine and feces will help prevent the conditions that lead to diaper rash. Since their introduction about 35 years ago, disposable baby diapers have undergone many design and performance changes. In particular, the performance of diapers was advanced by the introduction of absorbent gel materials(AGMs) to provide advantages in skin care, dryness, and leakage protection. Especially, important was the introduction of AGM which increased the absorbent capacity of the diaper several fold and yielded marked reductions in the degree of skin hydration occurring under the diaper. Studies show not only drier skin but more stable skin pH and less dermatitis with AGM diapers than with home-laundered cloth diapers or single-use diapers without AGM. Minimizing diaper area skin wetness is important for managing and preventing diaper rash. To minimize wetness, parents should use super absorbent diapers, change them frequently, and gently clean the perineal area with each diaper change. In addition to the skin care benefits, disposable diapers are also better than cloth diapers in minimizing the risk of diarrhea outbreaks among infants and toddlers in day-care environments by reducing fecal contamination and minimizing the potential for transmission of gastro-intestinal tract disease in day-care settings. Furthermore, disposable diapers in the hospital provide nursing, health care, and other advantages over cloth diapers: convenience for nurses and parents, and better containment than cloth with less handling, decreasing the chance of spreading infections. These benefits extend from the care of infants in hospitals to children at home or in day care centers.

Myocardial scintigraphy is a widely used noninvasive procedure with high sensitivity for the detection of patients with suspected coronary artery disease. The purpose of this study was to determine the prognostic value of a normal myocardial scintigraphy in 292 patients (150 males, 142 females, mean age 53+/-12 years) with chest pain who were followed from 7 to 58 (mean 25) months. Myocardial SPECT was performed with Tc-99m MIBI in 173 patients, with Tc-99m tetrofosmin in 74 patients and with T1-201 in 45 patients. During the follow-up period, there were 2 cardiac deaths and 2 nonfatal myocardial infarctions resulting in cardiac event rate of 1.37% (0.66% per year). The cardiac event rate was not different in patients with angiographically normal coronary arteries (1/30, 3.3%) and in those who had significant coronary a disease (2/27, 7.4%) (p=0.60). In conclusion, patients with chest pain and normal myocardial scintigraphy have a low cardiac event rate, and there was no significant difference of cardiac event rates between patients with normal and abnormal coronary angiograms.

PURPOSE: There has been little research regarding the effectiveness of oseltamivir for influenza B infections. We sought to identify the different clinical manifestations between patients treated with and without oseltamivir. METHODS: We retrospectively studied the medical records of 72 inpatients or outpatients from two medical centers diagnosed with influenza B infections by either a rapid antigen test or multiplex reverse transcriptase PCR between January 2012 and July 2012. We compared gender, age, past medical history, admission period, total fever duration, fever duration after hospitalization, post-oseltamivir medication peak temperature, laboratory test, chest X-ray, antibiotic medication, and the presence of concomitant viral or bacterial infections. RESULTS: The number of subjects in our study was 72 who were diagnosed with influenza B pneumonia, acute bronchitis, acute bronchiolitis, croup, and mean age was 3.6+/-2.8 year old. The demographic characteristics and clinical manifestations of oseltamivir and the non-oseltamivir groups, including hospitalization period (4.18+/-2.10 vs 4.79+/-1.49 days, P=.17) and total fever duration (5.32+/-2.07 vs 6.41+/-3.25 days, P=.09), demonstrated no significant differences. Notably, the oseltamivir group did have significantly reduced usage of antibiotic treatment than the non-oseltamivir group (P=.04). When we limited our patient group to patients under the age of three, similar results were seen. The group prescribed oseltamivir within 48 hours of fever onset had less antibiotic usage, in addition to a shorter fever duration. CONCLUSION: Oseltamivir appeared to have no benefit in improving the clinical course. However, if it is prescribed within the first 48 hours of symptoms, it may be more effective.

10.Pain Insensitivity and Pressure Pain Thresholds in Patients with Schizophrenia.
Journal of Korean Neuropsychiatric Association 2000;39(1):14-22
OBJECTIVES: Decreased pain sensitivity to the external stimuli was sought by measuring the pressure pain thresholds in patients with schizophrenia. In the case of the pain insensitivity(PI) being confirmed, the relationship between psychiatric symptoms and PI was to evaluated. METHODS: 21 schizophrenic and 23 healthy controls were enrolled. Pressure pain thresholds(PPT) were measured by pressure algometer on initial and recovered phase, and positive and negative symptoms by PANSS(Positive and Negative Symptoms Scale)(Stanley et al. 1991) were obtained in patient group. The confounding factor induced by antipsychotics to the PPT was controlled for. Comparisons of PPT between two groups, and correlations of PPT and psychiatric symptoms in patient group were tested. RESULTS: 1) Schizophrenic patients with active psychotic symptoms showed higher PPT compared to healthy controls. 2) When psychiatric symptoms were improved, PPT was decreased to the level of healthy controls. 3) Only the subscale of delusion in PANSS was closely correlated with PPT in patients with schizophrenia. 4) The dose of antipsychotics did not influence the PPT of the patient group. CONCLUSIONS: A part of patients with schizophrenia revealed they had higher pressure pain thresholds, which suggested PI in active symptom phase. However, PPT were restored almost to the level of normal controls when psychotic symptoms were improved. Thus, PI seemed to be a transient phenomenon rather than a persistent one. Changes of pain sensitivity to the external stimuli in schizophrenics would be associated with severity of delusion based upon reversible changes of brain function. Decreased attention due to delusion or lack of motivation seemed to be causal factors of PI. Clinicians should give attention to PI in schizophrenic patients to prevent physical illness and serious injuries in them.
