Juvenile xanthogranuloma is characterized histologically by a dense, sheetlike, well-demarcated, histiocytic infiltration within the papillary and reticular dermis, with occasional extension into subcutaneous tissue, fascia, and peripheral muscle. We report a case of juvenile xanthogranuloma developed in a 5-month-old male infant which showed typical histopathologic features of juvenile xanthogranuloma, involving the papillary dermis only without deep dermal or subcutaneous change.

This study was conducted to evaluate the effect of a teaching program on patients with myocardial infarction. Forty-five patients were randomly selected 22 were assigned to a teaching group and 23 to a control group. An individualized teaching program was delivered to the teaching group during the hospitalization period. It covered aspects such as: the characteristics of heart disease, the anatomy and physiology of the heart, risk factors of atherosclerosis, medication and diet and exercise therapy. When these subjects were discharged to their homes, they received regular supportive care via telephone or mail for 12 weeks. Atherosclerotic risk factors, including, smoking, exercise, blood lipid profile and BMI were measured before and after the teaching program. Post-testing revealed that the numbers of those who exercised and the number of non-smokers were significantly higher in the teaching group than in the control group. Increased HDL cholesterol (High-Density Lipoprotein cholesterol) was significantly greater in the teaching group than in the control group. The above findings suggest that this individualized teaching program might be helpful at reducing the risk factors of atherosclerosis in myocardial infarction patients.

BACKGROUND: Stunned myocardium may be mediated by intracellular Ca2+ overloading or oxygen derived-free radicals. Halothane and propofol have been shown to block Ca2+ channels. Propofol is also known to have antioxidant properties. The present study was aimed to investigate the effects of anesthetics on recovery of postischemic, reperfused myocardium in open-chest dogs. Incidence of ventricular arrhythmia upon ischemia and reperfusion was also determined. METHODS: Forty dogs were subjected to 15 min occlusion of left anterior descending coronary artery (LAD) followed by 3 hr reperfusion during halothane (n=10), fentanyl (n=12), or propofol plus fentanyl (n=11) anesthesia. Regional contractile function was assessed using percent systolic shortening (%SS), the preload recruitable stroke work slope (Mw), and peak systolic intramyocardial pressure (IMPs). Diastolic function was evaluated using time constant for isovolumic intramyocardial pressure decline of left ventricle (IMP-tau) and percent post-systolic shortening (%PSS). RESULTS: %SS in the halothane, fentanyl, and propofol-fentanyl groups was similar at 3 hours of reperfusion (58%, 60%, and 55% of baseline value, respectively). Moreover, Mw recovered to the baseline values in the early reperfusion period in all three groups. However, IMP-tau was significantly prolonged in the halothane group throughout the 3 hour reperfusion period, whereas it remained unchanged in the fentanyl and propofol-fentanyl groups. Coronary occlusion was associated with 9, 33, and 0% mortality rate due to ventricular fibrillation upon ischemia and reperfusion in the halothane, fentanyl, and propofol-fentanyl groups, respectively. CONCLUSION: These findings indicate that halothane, but not fentanyl and propofol- fentanyl, impairs myocardial relaxation, while recovery pattern of contractile function do not differ among three groups, and that halothane and propofol reduce reperfusion arrhythmia in the canine model of myocardial stunning.

Purpose:
This descriptive study investigated the effects of nurses’ knowledge of withdrawalof life-sustaining treatment, death anxiety, and perceptions of hospice care on their attitudes toward withdrawal of life-sustaining treatment.
Methods:
Data were collected from 262 nurses at tertiary hospitals, general hospitals, or primary hospitals in Busan, Korea, and statistically analyzed using the t-test, analysis of variance, the Scheffé test, Pearson correlation coefficients, and hierarchical regression analysis.
Results:
The participants’ scores were 3.68±0.45 (out of 5) for attitudes toward withdrawal of life-sustaining treatment, 0.65± 0.15 (out of 1) for knowledge of withdrawal of life-sustaining treatment, 2.61±0.26 (out of 4) for death anxiety, and 4.06±0.43 (out of 5) for perceptions of hospice care. Furthermore, knowledge of withdrawal of life-sustaining treatment and perceptions of hospice care showed positive correlations with attitudes toward withdrawal of life-sustaining treatment, while death anxiety showed a negative correlation. The most significant factors influencing attitudes toward withdrawal of life-sustaining treatment were perceptions of hospice care, followed by having experienced caring for patients who withdrew life-sustaining treatment, death anxiety, having a spouse, and ethical values, and the overall explanatory power was 43.0%.
Conclusion
This study showed that perceptions of hospice were an important fac-tor influencing nurses’ attitudes toward withdrawal of life-sustaining treatment. Therefore,it is necessary to develop and validate educational intervention programs that can improve perceptions of hospice care.

In approximately 10% of patients with acute myocardial infarction (MI), angiography does not reveal an obstructive coronary stenosis. This is known as myocardial infarction with non-obstructive coronary arteries (MINOCA), which has complex and multifactorial causes. However, this term can be confusing and open to dual interpretation, because MINOCA is also used to describe patients with acute myocardial injury caused by ischemia-related myocardial necrosis. Therefore, with regards to this specific context of MINOCA, the generic term for MINOCA should be replaced with troponin-positive with non-obstructive coronary arteries (TpNOCA). The causes of TpNOCA can be subcategorized into epicardial coronary (causes of MINOCA), myocardial, and extracardiac disorders. Cardiac magnetic resonance imaging can confirm MI and differentiate various myocardial causes, while cardiac computed tomography is useful to diagnose the extracardiac causes.

BACKGROUND/AIMS: Hepatic damage during transarterial chemoembolization (TACE) is a critical complication in patients with hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). Apart from its role in preventing HBV reactivation, there is some evidence for the benefits of preemptive antiviral therapy in TACE. This study evaluated the effect of preemptive antiviral therapy on acute hepatic deterioration following TACE. METHODS: This retrospective observational study included a prospectively collected cohort of 108 patients with HBV-related HCC who underwent TACE between January 2007 and January 2013. Acute hepatic deterioration following TACE was evaluated. Treatment-related hepatic decompensation was defined as newly developed encephalopathy, ascites, variceal bleeding, elevation of the bilirubin level, prolongation of prothrombin time, or elevation of the Child-Pugh score by ≥2 within 2 weeks following TACE. Univariate and multivariate analyses were conducted to identify factors influencing treatment-related decompensation. Preemptive antiviral therapy involves directing prophylaxis only toward high-risk chronic hepatitis B patients in an attempt to prevent the progression of liver disease. We regarded at least 6 months as a significant duration of preemptive antiviral treatment before diagnosis of HCC. RESULTS: Of the 108 patients, 30 (27.8%) patients received preemptive antiviral therapy. Treatment-related decompensation was observed in 25 (23.1%) patients during the follow-up period. Treatment-related decompensation following TACE was observed more frequently in the nonpreemptive group than in the preemptive group (29.5% vs. 6.7%, P=0.008). In the multivariate analysis, higher serum total bilirubin (Hazard ratio [HR] =3.425, P=0.013), hypoalbuminemia (HR=3.990, P=0.015), and absence of antiviral therapy (HR=7.597, P=0.006) were significantly associated with treatment-related hepatic decompensation. CONCLUSIONS: Our findings suggest that preemptive antiviral therapy significantly reduces the risk of acute hepatic deterioration. Preventing hepatic deterioration during TACE by applying such a preemptive approach may facilitate the continuation of anticancer therapy and thus improve long-term outcomes.

OBJECTIVE: The purpose of this study was to evaluate the incidence of inability to flex proximal interphalangeal (PIP) and distal interphalangeal (DIP) joint in normal Koreans. The opposition palm ratio and thumb index ratio was also of interest. METHOD: Randomly selected eighty nine normal Korean adults of 48 men and 41 women, with ages 20 to 79 years. The finger flexion was measured using the standard flexor digitorum superficialis (FDS) and flexor digitorum profundus (FDP) screening tests. Thumb index ratio and opposition palm ratio was also assessed additionally. RESULTS: In the sample population, 2 subjects (2.2%) were unable to bilaterally flex their fifth PIP joints independently. Four subjects (4.4%) were unable to flex one or both of their fourth or fifth DIP joints. These results show far less incidence of FDS dysfunction comparing with 52% of FDS dysfunction rate in Americans. The opposition palm ratio in men were 63.6% and in women 69.9%, indicating lower ratio in men. The thumb index ratio was not different statistically between the men and women. CONCLUSION: These data suggest that the different incidences of FDS and FDP dysfunction should be considered in interpretation. The opposition palm ratio and thumb index ratio might be useful in the hand rehabilitation.

FSH is the pivotal hormone in the regulation of ovarian function and acts by binding to specific receptor, FSH receptor (FSHR), which is belong to the family of G-protein coupled receptor. It have been considered that ovary is the only target organ of FSH because FSHR mRNA was first detected in ovarian follicles. However expression of FSHR mRNA was also detected on fallopian tube in experimental animal study and it is related wih tumorigenesis in postmenopausal women.In this study, in order to understand the FSH function in female genital organs, the ontogeny of the production profile of FSHR and the pattern of its localization in female genital organs were studied. We obtained the fresh tissues of ovary, fallopian tube, uterine body and uterine cervix with blood samples during proliferative phase in women with regular menstrual cycle. To establish FSHR mRNA expression of human internal genital organ, we studied by using in situ hybridization and quantitative competitive reverse transcription polymerase chain reaction (QC RT-PCR). To localize FSHR transcripts by in situ hybridization, we synthesized digoxigenin-labelled ssRNA probe (about 800 bp) from the cloned FSHR cDNA. For QC RT-PCR, we designed oligonucleotide primers (antisense: 5'-GGCCCTGCTCCTGGTCTCTTTG-3', sense: 3'-AACAGCGGGAGTACCTTCGG-5') which produced 799 bp sized PCR products. Simultaneously we synthesized 149 bp deleted DNA competitor by site-directed mutagenesis to quantify target FSHR mRNA expression comparing as internal control.In situ hybridization with digoxigenin-labelled ssRNA probe showed no signal above the background in primordial follicles. FSHR mRNA was first detected in the single layer of cuboidal granulosa cells surrounding primary follicles. As follicular growth progressed, FSHR mRNA expression increased gradually in antral and graafian follicles. Similary, in fallopian tube, the epithelium stained intensly. But FSHR mRNA expression was absent in uterine body including endometrium and myometrium and uterine cervix. Total RNA was extracted and quantitated by QC RT-PCR. The amounts of FSHR transcript measured were 840.00+/-516.29 in the ovarian tissue, 240.00+/-154.91 in the fallopian tube, 6.06+/-4.13 in the uterine body, 5.48+/-5.00 fg in the uterine cervix. These experiments demonstrated that FSHR mRNA is expressed in the ovary and fallopian tube, albeit only small amount was expressed in uterine body and cervix.In conclusion, the presence of FSHR mRNA in female internal genital organ with site specific pattern suggested that FSH may have some role in female genital organs during the adult reproductive cycle and may act as an factor in the tumorigenesis. Further study about the functional role and tumorigenesis of FSH should be performed in human internal genital organ.
