Desmoplastic small round cell tumor (DSRCT) is a rare neoplasm of young adults and it is characterized by polyphenotypic differentiation. We experienced a case of abdominal DSRCT that occurred in a 19-year-old female who presented with painful swelling of her right forearm. The tumor was cytokeratin-negative and it exhibited some tumor cells with intranuclear inclusions. Molecular demonstration of EWS-WT1 fusion transcripts is particularly useful to confirm the diagnosis of DSRCT without epithelial differentiation. We report here on a case of cytokeratin-negative DSRCT that showed an unusual feature of intranuclear inclusions.

Background & Objective: EGB 761 is a standardized natural extract used to treat impaired cerebral
perfusion and nutrition (cerebrovascular insufficiency) in Korea. Although several animal studies have
been conducted, few studies have investigated the clinical effects of EGB 761 in acute stroke. This
study assessed the clinical benefit of intravenous EGB 761 in patients with acute ischemic stroke.
Methods: This retrospective study examined a prospectively collected stroke database. We evaluated
232 patients with acute ischemic stroke within 48 hours of symptom onset. All patients were treated
with antiplatelet or anticoagulation agents. We compared baseline characteristics between the EGB
761-treated and non-treated groups. The functional outcome measure was the modified Rankin Scale
(mRS) score 90 days after stroke onset. Results: Of the 232 patients, 170 received EGB 761 during the
first 3 days after arrival in the emergency department. We found no significant differences in baseline
characteristics between the groups, with the exception of atrial fibrillation (p=0.032). After adjusting
for baseline factors, intravenous administration of EGB 761 was associated with an improved 90-day
functional outcome (mRS ≤2) compared with the control group (odds ratio, 2.56; p<0.05).
Conclusions: Our results showed a clinical benefit of intravenous EGB 761 in patients with acute
ischemic stroke

Beckwith-Wiedemann syndrome is a rare clinical entity characterized by exomphalos, macroglossia, macrosomia, and renal hyperplasia/dysplasia. Although its entity is established, its etiology and obligatory features have not been settled. We report an autopsy case with the unusual involvement of the salivary gland. This infant was born to a 37-year-old mother as a normal full-term spontaneous delivery. At 11 days of age she developed with purulent eye discharge and weak sucking, and died suddenly. At autopsy the baby weighed 2,630 gm and the head circumference was 35 cm. She showed thick and prominent skin folds, bilateral aural fissures, macroglossia, hepatomegaly, cardiomegaly, dysmorphic kidneys, and nesidioblastosis. Both kidneys showed dysplastic tubules and hyperplastic cortical tissue enclosing the medulla. In this case there were characteristic findings in major and minor salivary glands with both acinar and ductal hyperplasia, and hypertrophy of mammary glands. Besides, she had generalized depletion of subcutaneous fat, immature buccal fat, patent ductus arteriosus, hyperlobation of the right lung, two accessory spleens, and hyperplasia of basophils and chromophobes in the pituitary gland. The lungs showed diffuse interstitial pneumonia and multiple fibrin thrombi. There were no adrenal cytomegaly, umbilical hernia and exophthalmos.

The purpose of the study was to investigate two areas as a basis for providing an educational program for pulmonary rehabilitation. A) the learning needs about chronic obstructive pulmonary disease in patients with chronic obstructive pulmonary disease and B) the perception of nurses of the same learning needs. The subjects consisted of 57 patients, with chronic obstructive pulmonary disease, at the general hospital in Seoul and 71 nurses, who were working in the medical ward. Data was obtained from a "learning need" questionnaire between October 29 and November 19, '99. Data was analyzed using SAS program for t-test, ANOVA, Scheff test. The result were as follows: 1. The learning needs of the nurses(mean 4.36 +/- .38) were higher than those of the patients (mean 3.56 +/- .83). (t=6.78, P=.001) 2. The highest ranked patient education needs were as follows ; a)"how to control dyspnea", b)"cause for activating dyspnea", and c)"how to minimize the necessity of oxygen in daily living": and nurses' learning needs were ; a)"how to cope with the risk situation", b)"management after discharge", and c)"how to control dyspnea". 3. In the patient group, those who had a college degree or higher education and paid their own hospital expenses were higher in the learning needs. According to the above results, we should consider an educational program which is realistic and effective for patients by evaluating the items the patients really want to learn about and how much they know about the evaluated items.

To define the basic sequential events of the healing process in normal fracture and evaluate the role of growth regulatory molecules and extracellular matrix components, the expression of transforming growth factor β(TGF-β), platelet-derived growth factor(PDGF), type I and II collagen, and chemistry during the healing process of an experimental fracture of tibia in 41 adult rats for 7 weeks using ABC methods. The phases of inflammation, reparation, and remodeling followed each other in sequence. The inflammatory phase was characterized by hemorrhage, edema, and infiltration of inflammatory cells on the first day. During the reparative phase, the undifferentiated mesenchyme undergoes rapid chondrogenesis, followed by endochondral ossification and supplemented by appositional bone formation. At day 3, the expression of TGF-β and PDGF was noted in the undifferentiated mesenchymal cells and from day 5, these two growth factors were detected in the osteoblasts and extracellular matrix in areas of endochondral ossification and newly formed periosteal bone. From day 3, the expression of type I collagen and osteonectin was noted in the osteoblasts and extracellular matrix in both endochondral ossification and appositional bone growth as a marker of ossification. From day 3, type III collagen was mainly expressed in the plump mesenchymal cells showing chondroid differentiation and chondroid matrix as a marker of cartilaginous reparative phase. From day 14, these growth factors and extracellular matrix components were decreased in staining intensity and at the 5th week, the histology and immunostaining pattern were similar to the mature bone.

Purpose:
The objective of this study was to analyze the effects of non-pharmacological interventions on cancer patients with sleep disorder.
Methods:
A total of 4,246 studies published between 2000 and 2018 were identified by searching NDSL, RISS, Koreamed, PubMed, EMBASE, Cochrane Library, and CINAHL. Seventeen of these studies were selected for inclusion in the meta-analysis.Data were analyzed using the Comprehensive Meta-Analysis (CMA) Ver. 3.4.1 program, and the effect sizes were shown using Hedges’ g score.
Results:
Intervention studies included 8 studies on exercise, 4 studies on cognitive-behavioral therapy, 2 studies on music, and 1 study each on aromatherapy, massage, and mindfulness-based stress reduction. The overall controlled effect size was .78 (95% Confidence Interval=.40, 1.16, Z=4.02, p<.001), using a random effects model.
Conclusion
Through this study, it was found that the effects of exercise (walking), aromatherapy, massage, and music intervention were all statistically significant. As such, the findings of this study provide evidence supporting the incorporation of various non-pharmacological interventions into nursing practice to improve sleep quality in patients with sleep disorder.

Background: We hypothesized that intravenous lidocaine mixed with propofol may have an influence on anesthesia induction and hemodynamic responses to propofol induction and endotracheal intubation as well as propofol-induced pain on injection. Methods: Seventy-five patients were allocated to group L1 (2% lidocaine 1.5 mg/kg, n=25), group L2 (2% lidocaine 2 mg/kg, n=25) or group C (normal saline 0.05 mL/kg, n=25) according to the lidocaine dosage mixed with propofol 2 mg/kg. The pain on injection was scored as none, mild, moderate, and severe. The site of pain and recall of pain were also recorded. Loss of verbal response was observed during induction. Mean arterial blood pressure (MAP) and heart rate (HR) were recorded before anesthetic induction (baseline value), immediately before and after endotracheal intubation, and every min until 5 min thereafter. Results: Ninety-two percent of patients reported pain upon injection in group C, whereas 8% of the patients in group L1 and no patient in group L2. Loss of verbal response before injection of total dose of propofol was observed in 44% in group L2, 36% in group L1 and 28% in group C. Lowered MAP caused by propofol increased significantly after endotracheal intubation in all three groups (p<0.05). HR increased immediately and 1 min after endotracheal intubation in all three groups (p<0.05). Conclusions: Our results indicate that intravenous lidocaine 1.5 mg/kg or 2 mg/kg mixed with propofol 2 mg/kg significantly reduces the incidence and the degree of pain, but does not affect anesthesia induction and hemodynamic responses to propofol and tracheal intubation.

PURPOSE: To determine the characteristics of benign breast calcifications on mammogram. MATERIALS AND METHODS: Benign breast calcifications on mammograms of 25 patients, which were confirmed by needle localization and excisional biopsy(15 cases), cytology(1 case), or follow-up study(9 cases), were retrospectively analysed according to size, shape, number, distribution, and density. RESULTS: The size of benign breast calcifications was uniform in 4 cases (16%), and variable in 21 cases (84%). The shape of calcifications was round or oval in 18 cases(72%), linear or branching pattern in 6 cases (24%), and irregular in 1 case(4%). The number of calcifications was 2-5 in 7 cases(28%), and over 6 in 12 cases(48%). The distribution of calcifications was focal in 13 cases(52%) and diffuse in 12 cases(48%). The density of calcification was homogenous in all 25 cases(100%). CONCLUSION: Analysis of number, shape, size, and distribution is helpful for the diagnosis of benign breast calcifications. However the homogenous density of the calcification is suggested to be the most helpful criterion for the diagnosis of benign breast calcifications.

BACKGROUND/AIMS: To investigate the diagnostic performance of diffusion-weighted imaging (DWI) for hepatic neuroendocrine tumors (NET) compared with combined DWI and contrast-enhanced magnetic resonance imaging (MRI). METHODS: Fifteen patients with hepatic NET (n=128) underwent enhanced MRI and DWI with multiple-b values. We analyzed three different sets: Precontrast set; DWI set (added DWI); combined set (added enhanced image). Two reviewers rated possibility of NET using a 5-point scale for each image set. Their diagnostic performance was compared using Jackknife alternative free-response ROC (JAFROC). RESULTS: Diagnostic performance was better on the combined set (figure of merit [FOM]=0.852, 0.761) than the precontrast set (FOM=0.427, 0.572, P〈0.05) and the DWI set (FOM=0.682, 0.620, P〈0.05). However, DWI improved performance compared with precontrast set without statistical difference. In small NETs (〈1 cm), all sets showed low sensitivity (10.7-65.9%) with high specificity (95.4-100%). Interobserver agreement was moderate in all image sets (k=0.521 to 0.589). CONCLUSIONS: Combined DWI and enhanced MRI were more useful for detecting NET. Although statistically insignficant, there was a trend in improved diagnostic performance with DWI.
