BACKGROUND: Controversy exists as to whether or not inhalation anesthetics and intravenous anesthetics impair arterial oxygenation (PaO2) during one lung ventilation (OLV). Accordingly, we examined the effect of enflurane and propofol on PaO2 and pulmonary vascular resistance (PVR) during OLV. METHODS: Forty patients, who had prolonged periods of OLV anesthesia with minimal trauma to the nonventilated lung were studied in a cross over design. Patients were randomized to four groups; Group 1 received 1 MAC of enflurane and oxygen from induction until the first 20 min after complete lung collapse, then were switched to propofol 100 g/kg/min (P100). In group 2, the order of the anesthetics was reversed. Group 3, Group 4 received the same order of the anesthetics as Group 1, Group 2, respectively but received propofol 200 g/kg/min (P200). RESULTS: During OLV, the PaO2 values were lower than those with two lung ventilation (TLV), there were no significant differences among each groups and between propofol and enflurane in PaO2, but in the selected patients (n=10, PaO2<120 mmHg during OLV), PaO2 in propofol group was higher than that of enflurane group (p<0.05). Conversion from TLV to OLV caused a significant increase in PVR, but there were no difference in PVR between propofol and enflurane group. CONCLUSIONS: These results suggest that the usual clinical dose of propofol affords no advantage over 1 MAC of enflurane anesthesia except low PaO2 patients during OLV. Propofol might be of value in risk patients of hypoxemia during thoracic surgery when OLV is planned.

We examined 984 objects for exercise stress test, using CASE I(computer assisted system for exercise). They exercised according to Bruce's protocol, Among them, the mal were 613 and the female were 371. (Male:Female;17:1) The 5th and 6th decades occupied 61% of total objects. The purpose of test was evaluation of chest pain in 84% of total cases. The most frequent end point of test was dyspnea(42%) and chest pain was observed in 13% of total cases. Most of all objects above 8-9 METS. Positive results of exercise stress tert were obtained in 23%. As complications, ventricular tachycardia occurred in 7 cases, supraventricular tachycardia; 8, high degree VPB's; 6, sudden cardiovascular collapse;15, The complication rate was 0.36% but morbidity and mortality were 0. All complicated cases recoved spontaneously only by rest.

PURPOSE: Perinatal asphyxia occurring in newborn is one of the major causes of acute mortality and chronic neurological disability in survivors. We have studied the relationship between early electroencephalography(EEG) findings and clinical course and neurologic outcome in severe asphyxiated neonates. METHODS: Between the period of July 1999 and June 2002, 25 neonates who were diagnosed with severe perinatal asphyxia(1-minute Apgar score of < or =3 and initial pH is less than 7.2) at NICU in Dongsan Medical Center were enrolled. An EEG was recorded and analyzed within three days of life and divided into two groups - group 1(normal or focal change on EEG) and group 2(generalized abnormal EEG). Between the two groups, clinical courses and neurologic outcomes were compared. RESULTS: Fifteen infants(60%) were group 1 and ten infants(40%) were group 2(polyspikes, burst- suppression, generalized low voltage). Associated maternal disease, days of hospitalization, need for ventilator support, delay of oral feeding and convulsion duration are significantly higher and longer in group 2. Also, poor neurologic outcome(expire, developmental delay) was significantly higher in group 2(60%) than group 1(13.3%). CONCLUSION: Thus, the early neonatal EEG in asphyxiated newborn can be a predictable diagnostic tool in assessment of neurologic outcome.

BACKGROUND: Trichomonas vaginalis is a pathogenic protozoa infecting human genitourinary tract. Metronidazole is currently the drug of choice to treat T. vaginalis infection. However, because of the side effects and the occurrence of resistant strains of metronidazole, it is needed to investigate alternatives. METHODS: The antiprotozoal effect of aquatic extract from Sophora flavescens on the growth and fine structure of T. vaginalis was examined by using trypan blue exclusion assay and electron microscopy. RESULTS: One hour after the addition of 4 mg/mL extract and half hour after the addition of 5 mg/mL showed antiprotozoal effect. One to two hours after the addition of 3 mg/mL extract, the movement of flagella and axostyle had disappeared, but death of the cells had not occurred until two hours after the addition. The fine structure of the cytoplasm was also changed half an hour to two hours after addition. The number of polyribosome decreased when that of single ribosomes in the cytoplasm increased. CONCLUSION: These results indicated that S. flavescens had the antiprotozoal effect on T. vaginalis by inhibition of cell multiplication as well as an impairment of protein synthesis.

To investigate long term effects of CAPD on the left ventricular function in end-stage renal disease patients, M-mode echocardiographic studies and measurement o fsystolic time intervals were performed in 20 CAPD cases, 28 hemodialysis cases and 29 uremic controls. Compared to the uremic control grup, the patients on CAPD treatment revealed significant improvement of ventricular contractility and reduction of volume. On the other hand in hemodialysis group, even though there was improvement of ventricular contractility, volume control was not adequate. In the systolic time interval measurement, it is postulated that increase of PEP/LVET ratio in CAPD group probably results from reduction of volume(preload) rather than from deranged ventricular function.

Crohn's disease of the perineum is notably resistant to treatment. We describe our experiences of tacrolimus ointment application in three patients with intractable perianal Crohn's disease. At the time of diagnosis patients showed anal fissure with ulcer, anal fistula, or perianal abscess, respectively. These lesions did not respond to steroid, metronidazole, mesalazine, or azathioprine, though the pediatric Crohn's disease activity index was markedly improved during the treatment period (4 to 12 months). Topical tacrolimus was applied and resulted in marked healing and a rapid granulation of cavity edges within 6 weeks to 3 months. Topical tacrolimus at a low dose shows a promise for the management of childhood perianal Crohn's disease. Further controlled studies are required to assess the efficacy and safety of this treatment.

Journal of Korean Academy of Psychiatric and Mental Health Nursing 2022;31(4):458-468
Purpose:
The purpose of this study is to find out the meaning of self-care experiences of family members of mentally ill patients and describe its essential structure.
Methods:
The Giorgi's phenomenological research methodology was used. Six families participated in this study. In-depth individual interviews were used to collect data from October to December in 2021.
Results:
Five clusters of themes were identified. They were “Selfless life”, “Life on shaky grounds”, “Attempts to escape from the suffering”, “Moving forward on self-care path”, and “Happiness blooming in being together”.
Conclusion
The findings suggest that mental health care professionals should provide educational programs to enable families of patients with mental illness to recognize the necessity for self-care and discover ways to take care of themselves. In addition, it is necessary to develop policies to expand patient management services at mental health welfare centers so that families of patients with mental illness can secure time for self-care.

Purpose:
As the daily life experiences of community-dwelling people with mental disabilities are closely correlated to mental health recovery, this study aimed to analyze their daily life experiences in depth to determine their significance. Method: Participants included eight community-dwelling people with mental disabilities. A total of 12 in-depth interviews were conducted once or twice per participant. The collected data were analyzed using the phenomenological analysis method described by Giorgi.
Results
The daily life experiences of community-dwelling people with mental disabilities were categorized into the following four components: “encountering shocking reality in the outside world”, “life tied down by the mental illness”, “happiness and gratefulness encountered in daily life”, and “wishing for a change and self-sustaining life”. Conclusion: This study found that the recovery and welfare of community-dwelling people with mental disabilities were promoted and that these patients made necessary efforts to become a member of the local community. These findings could be used as a reference for establishing social welfare policies which enable people with mental disabilities to participate as functioning members of the community that facilitate the prevention of relapse, to promote their integration into the community. Furthermore, the present results will contribute to the development of nursing intervention programs to promote recovery and prevent relapse, to ultimately establish a mental health management system.
