BACKGROUND: The more vital organ blood flow during cardiopulmonary resuscitation (CPR), the more successful outcome. The worldwide CPR drug of choice, epinephrine also has some limitations and is often challenged by another catecholamine drug. This study was designed to compare the effects of epinephrine with those of vasopressin and epinephrine mixture on cerebral no-reflow during closed-chest CPR in a rabbit model of ventricular fibrillation. DESIGN: Prospective, randomized, experimental study. SETTING: University research laboratory. SUBJECTS: Domestic rabbits,3 to 6 months of age InteNentions : Four rabbits were randomly allocated to receive only 0.020 mg/kg of epinephrine(group 1) and another four rabbits were received both 0.020 mg/kg of epinephrine and 0.8 U/kg of vasopressin after 5 mins of cardiac arrest(group 2). MEASUREMENTS AND MAIN RESULTS: Carotid arterial blood flow and arterial gas analysis were showed no statistical difference between two groups but in the points of cerebral no reflow area and fluorescence exposure time, there were significant differences(group 1,5.15+/-.45%, group 2, 6.38+/-.54%, p=.029/ group 1; 29.65+/- 17.09 seconds, group 2;17.98+/- 18.75 seconds, p=.014). CONCLUSIONS: In cardiac arrest there is some synergistic effect with epinephrine and vasopressin mixture on cerebral no-reflow phenomenon.

PURPOSE: Nowadays, concern about the care of one's offspring has been increasing due to increased active participation of wornen in society and having fewer children than in the past. Therefore, we performed a study to evaluate the rnajor fields of child care counselling and establish effective child care counselling. METHODS: We retrospectively analyzed 2,754 cases of child care counselling about sex ratio, distribution of age, major fields of concern and major questions of each field using personal computer communication from April 1994 to March 1999. RESULTS: Sex distribution was usually unknown. The most frequent questions concerned the infantile period, especially less than 6 months of age. Nutrition, digestive system, development and psychology were the major fields of child care counsellng. CONCLUSION: We conclude that the major period of child care counselling was during the infantile period, and there was a major concern about nutrition, development and psychology. But, more efforts and studies are needed to establish effective child care counselling.

BACKGROUND: Portable devices for measuring peak expiratory flow(PEF) are now of proved value in the diagnosis and management of asthma and many lightweight PEF meters have become available. However, it is necessary to determine whether peak expiratory flow rate(PEFR) measurements measured with peak flowmeters is accurate and reproducible for clinical application. The aim of the present study is to define accuracy, agreement, and precision of mini-Wright peak flow meter(MPFM) against standard pneumotachygraph. METHODS: The lung function tests by standard pneumotachygraph and PEFR measurement by MPFM were performed in a random order for 2 hours in 22 normal and 17 asthmatic subjects and also were performed for 3 successive days in 22 normals. RESULTS: The PEFR measured with MPFM was significantly related to the PEFR and FEV1 measured with standard pneumotachygraph in normal and asthmatics(for PEFR, r=0.92 p<0.001; for FEV1, r=0.78 ; p<0.001). The accuracy of MPFM was within 10%(limits of accuracy recommeded by NAEP) in all the subjects or 22 normal, mean difference from standard pneumotachygraph being I 6.5L/min(percentage of difference being 2.90%) or 1 0.6L/min(percentage of difference being 1.75%), respectively. According to the method proposed by Bland and Altman, the 95% limits of the distribution of differences between MPFM and standard pneumotachygraph after correction of PEFR using our regression equation were +38.2 and -71.5L/min in all the subjects or -20.49~ + 9.49L/min in 22 normal and was similar to the intraindividual agreements for 3 successive days in normal. There was no statistically significant difference of PEFR measured with MPFM and standard pneumotachygraph among three days(p>0.05) and the coefficient of variation(2.4 1.2%) of PEFR measured with MPFM was significantly lower than that( 5.2 3.5%) with standard pneurnotachygraph in normal (p<0.05). CONCLUSION: This results suggest that the MPFM was as accurate and reproducible as standard pneumotachygraph for monitoring of PEFR in the asthmatic subjects.

Spindle cell hemangioendothelioma was first described in 1986 by Weiss and Enzinger as a low grade angiosarcoma resr mbling a cavernous hemangioma and kaposis sarcoma. Recently, it is suggested to be non neoplastic lesion or reactive process arising from pre-existing vascular mal- formation. We report a case of spindle cell hemangioendothelioma in a 9-month-old boy. He had multiple, variable sized, colorful, cutaneous or subcutaneous nodules on the forearm and hand. The tumor first appeared on the forearm as erythematous patches at birth and grew rapidly with- in 3 months. Histopatholgical findings showed that the lesion was composed of thin walled cavernous spaces mixed with spindle cells and occasional epithelioid endothelial cells containing intracytoplasmic vacuole. Most af the endothelial cells lining the cavernous spaces and intracytoplasmic lumina, were positive for factor VIII associated antigen. But the spindle cells were negative. Atypical vascular structures resembling arteriovenous shunts were noted around the tumor suggesting a reactive proliferation due to disturbance of local blood flow. Several turnors were excised. No recurrence has been recognized in the one year- follow-up period.

BACKGROUND: The bcl-2 is an oncogene involved in tumorigenesis by blocking apoptosis, or programmed cell death and over-expression of bcl-2 protein has been reported in several malignant tumors such as lung cancer, basal cell carcinoma, breast cancer and malignant melanoma. However, there have been only a few studies about bcl-2 expression of cutaneous T cell lymphoma. OBJECTIVE: The purpose of this study was to examine whether there is any difference in expression of bcl-2 between mycosis fungoides(MF), angiocentric T cell lymphoma, angioimmunoblastic T cell lymphoma, subcutaneous T cell lymphoma and anaplastic large cell lymphoma. We also evaluated the statistical significance between expression of bcl-2 and the prognosis of the diseases. METHODS: Routine paraffin sections of formalin-fixed 36 tissues (14 MF, 7 angiocentric T cell lymphoma, 5 subcutaneous panniculitic T cell lymphoma, 2 anaplastic large cell lymphoma, 1 angioimmunoblastic T cell lymphoma, 1 unspecified peripheral T cell lymphoma, 2 small plaque parapsoriasis, 2 psoriasis and 2 lichen planus) were labelled with anti-bcl-2 monoclonal antibody using an avidin- biotin-peroxidase complex. Normal skin for bcl-2 served as negative controls. RESULTS: The results were as follows. l. All cases of benign inflammatory diseases, small plaque parapsoriasis and patch stages of MF showed positive staining for bcl-2. Therefore, there were no differences in expression of bcl-2 among these diseases. 2. In the plaque and tumor stages of mycosis fungoides, statistically significancant differences in bcl-2 expression were not found during disease progression. 3. bcl-2 expression in peripheral T cell lymphoma (five in seven cases of angiocentric T cell lymphoma showed positive staining but all other peripheral T cell lymphoma was negative) decreased significantly (p<0.05) than that of MF. 4. No statistical significance was found between bcl-2 expression and prognosis of cutaneous lymphoma (p>0.05). CONCLUSION: These results suggest that the loss of bcl-2 expression may play a significant role in progression of cutaneous T cell lymphoma except in MF and angiocentric T cell lymphoma.

Clinical characteristics of papular-purpuric gloves and socks syndrome consist of a purpuric erythema affecting the hands and feet in a gloves and stocking distribution. It is sometimes associated with fever and oral lesions. The disease is self-limiting and resolves within 1 to 2 weeks. Serological studies have shown that there is an association with parvovirus B19 infection in most patients affected by this syndrome. We report a case of gloves and socks syndrome in a 21-year-old female. She had a 4-day history of papular-purpuric eruptions of the hands and feet in a gloves-and-socks distribution. She also complained of fever(up to 39C) during the first 2 or 3 days of clinical onset. The oral mucosa was normal and there were no palpable lymph nodes. Laboratory and histopathological findings were non-specific. However, human parvovirus B19 DNA was detected in the serum by a polymerase chain reaction. Systemic manifestations were transient and disappeared within a few days, whereas the skin lesions resolved gradually over a period of 2 weeks.

Spindle cell lipoma was first described in 1975 by Enzinger and Harvey as a variant of lipomas. Histopathological findings show the lipomatous tissue to be replaced by a mixture of uniform spindle cells and mature fat cells closely associated with a mucoid matrix and a varying number of collagen fibers. Immunohistochemical staining is reported to give assistance in the differential diagnosis af spindle cell lipoma from other fibrous or neural tumors. Also, it can be used to investigate the origin of the spindle cells. We report a case of spindle cell lipoma in a 41-year-old female. She had a solitary, normal skin colored, bean sized, subcutaneous mass on the forearm. Most of the spindle cells were strongly positive for vimentin, CD34 and NSE, but negative for actin, factor VIII, S-100 protein and neuro- filaments. The tumor was excised. No recurrence was recognized in a 10 month follow up period.

PURPOSE: The purpose of the study was to have an in-depth understanding of delivery room nurses'experiences of caring for stillborn babies and their parents. METHODS: After obtaining approval from the Institutional Review Board, data were collected from March 1 to August 30, 2016. A total of six nurses participated in the study. Semi-structured in-depth interviews were conducted and the data subsequently analyzed. RESULTS: Using thematic analysis, six themes were defined and refined: Emotional distress as a result of encountering stillborn babies; Caring for the deceased baby; Concerns for the mother's pain; Consideration for the father; Conflicts between accepting and dismissing parents' requests; and Strong mindset for the stillborn babies and their parents. CONCLUSION: The results showed that the nurses' experiences of caring for stillborn babies and their parents might be a difficult and lonely process. However, it could also be a process of attaining maturity by finding meaning and value in one's work. It would be helpful for the delivery room nurses to share examples of effective communication, train through simulation, and learn useful strategies that each nurse can use.
