Malignant eccrine poroma, or eccrine porocarcinoma, is a rare malignant cutaneous appendageal tumor arising from the intraepidermal eccrine sweat duct(acrosyringium), and usually develops ia an eccrine poroma of long-standing. We report a case of malignant eccrine poroma on the left buttock in a 72 year-old female. She was presented with a slightly pruritic, well-defined, reddish, firm, 4.5 x 4.5 x 0.7cm sized, protruding, ulcerated tumor. Histopathological examination revealed well-defined tumor cell nests in the epidermis and dermis. The tumor nests consisted of areas of eccrine poroma cells with benign appearance adjoining areas of anaplastic cells. Duct-like structures were observed within the tumor nests and showed a PAS-positive, diastase-resistant reaction. On immunohistochemical staining, the tumor cells were, positive for EMA, and most of tumor cells were negative but the duct-like structures were positive for CEA. She was treated with surgical excision. During the three year follow up period after excision, there was no recurrence.

Maspin is a recently described gene with tumor suppressor activity. The gene product is a 42 kD protein with homology to the serpin family of protease inhibitors and may play a role as an inhibitor of tumor cell invasion. The prior observation that invasive breast cancers and their metastases showed decreased maspin protein expression by immunostaining supports this speculation. However, the role of maspin in breast cancer progression has not been studied in detail. We, therefore, studied maspin protein expression in a series of hyperplasia, atypical ductal hyperplasia, intraductal carcinoma and invasive carcinomas. Immunohistochemical staining (IHC) for maspin was performed on paraffin sections of 136 breast specimens using a commercially available monoclonal antibody. Among the 106 cases studied were 36 moderate/florid ductal hyperplasia, 11 atypical ductal hyperplasia (ADH), 29 intraductal carcinoma (IDC) (4 low grade, 13 intermediate grade, 12 high grade) and 30 invasive ductal carcinomas. Thirty cases of normal breast were also studied as control group. IHC stains were scored using a semiquantitative scoring system. The mean IHC scores for maspin for normal, moderate/florid hyperplasia, atypical ductal hyperplasia, intraductal carcinoma, and invasive carcinoma were 5.51 1.30, 7.36 0.72, 3.82 1.60, 4.48 2.69, 3.97 3.30, respectively. These scores for each category were statistically significant (p<0.05), except between ADH and IDC. Maspin protein expression was increased in most cases of moderate/florid hyperplasia, while maspin expression was more heterogeneous in ADH and IDC. In high grade IDC, maspin protein expression was stronger than low and intermediate grade IDC, and this suggests the possibility of a compensatory cellular response against the forces driving further tumor progression. Two thirds of invasive ductal carcinomas expressed maspin protein weakly and focally. All metastatic carcinomas of lymph nodes were negative for maspin. It is possible that high grade IDC with strong maspin expression may represent a subset less likely to progress to invasive cancer. This speculation merits investigation in clinical outcome studies.

Macrophage-associated inflammation is crucial for the pathogenesis of diverse diseases including metabolic disorders. Rhodanthpyrone (Rho) is an active component of Gentiana rhodantha, which has been used in traditional Chinese medicine to treat inflammation. Although synthesis procedures of RhoA and RhoB were reported, the biological effects of the specific compounds have never been explored. In this study, the anti-inflammatory activity and mechanisms of action of RhoA and RhoB were studied in lipopolysaccharide (LPS)-stimulated macrophages. Pretreatment with RhoA and RhoB decreased inducible nitric oxide synthase and cyclooxygenase-2 expressions in RAW 264.7 cells and in thioglycollate-elicited mouse peritoneal macrophages. In addition, it downregulated transcript levels of several inflammatory genes in LPS-stimulated RAW 264.7 cells, including inflammatory cytokines/chemokines (Tnfa, Il6, and Ccl2) and inflammatory mediators (Nos2 and Ptgs2). Macrophage chemotaxis was also inhibited by treatment with the compounds. Mechanistic studies revealed that RhoA and RhoB suppressed the nuclear factor (NF)-κB pathway, but not the canonical mitogen activated protein kinase pathway, in LPS-stimulated condition. Moreover, the inhibitory effect of RhoA and RhoB on inflammatory gene expressions was attenuated by treatment with an NF-κB inhibitor. Our findings suggest that RhoA and RhoB play an anti-inflammatory role at least in part by suppressing the NF-κB pathway during macrophage-mediated inflammation.

Intestinal obstruction is a rare but important complication of pregnancy and puerperium leading to increased maternal and fetal motality. Diagnosis is often delayed or missed because many of the manifestations of intestinal obstruction such as nausea, vomiting and abdominal pain can be interpreted as pregnancy related symptoms. This delay in diagnosis or misdiagnosis, reluctance to surgery during pregnancy are thought to be responsible for the high maternal and fetal death rate. So we report a case of postpartum small bowel obstruction following vaginal delivery with a review of the literature.

OBJECTIVE: The aim of this study was to evaluate the efficacy of endovascular therapy as a primary treatment for spinal dural arteriovenous fistula (DAVF). METHODS: The authors reviewed 18 patients with spinal DAVFs for whom endovascular therapy was considered as an initial treatment at a single institute between 1993 and 2006. NBCA embolization was considered the primary treatment of choice, with surgery reserved for patients in whom endovascular treatment failed. RESULTS: Surgery was performed as the primary treatment in one patient because the anterior spinal artery originated from the same arterial pedicle as the artery feeding the fistula. Embolization was used as the primary treatment modality in 17 patients, with an initial success rate of 82.4%. Two patients with incomplete embolization had to undergo surgery. One patient underwent multiple embolizations, which failed to completely occlude the fistula but relieved the patient's symptoms. Spinal DAVF recurred in two patients (one collateral development and one recanalization) during the follow-up period. The collateral development was obliterated by repeated embolization, but the patient with recanalization refused further treatment. The overall clinical status improved in 15 patients (83.3%) during the follow-up period. CONCLUSION: Endovascular therapy can be successfully used as a primary treatment for the majority of patients with spinal DAVFs. Although it is difficult to perform in some patients, endovascular embolization should be the primary treatment of choice for spinal DAVF.

PURPOSE: The purposes of this study was to identify the effects of nursing practice environment, compassion fatigue and compassion satisfaction on burnout in clinical nurses. METHODS: Participants selected for the final analysis were 208 nurses working in 2 general hospitals in Busan and Masan. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation and Hierarchial Multiple Regression with SPSS/WIN 18.0. RESULTS: Compassion fatigue had a significant positive effect on burnout, while Compassion satisfaction had a negative effect on burnout, but Nursing practice environment had no effect on burnout. The explained variance for burnout was 61% and compassion satisfaction was the most significant factor in burnout of nurses. CONCLUSION: The results of this study indicate that to reduce burnout in clinical nurses it is necessary to develop programs to increase nurses' compassion satisfaction and decrease compassion fatigue.

OBJECTIVE: Reactive oxygen metabolites and polymorphonuclear leukocytes have been implicated in the pathophysiology of reperfusion injury. The mechanisms involved in superoxide-mediated leukocyte adherence remain unclear, however, nitric oxide(NO) may contribute to this response. The present study is undertaken to elucidate mechamisms controlling NO based mechanisms that regulated leukocyte-endothelial interactions in the cerebral vasculature after global cerebral ischemia and reperfusion. METHODS: Pial venular leukocyte adherence of anesthetized newborn piglets was quantified by in situ fluorescence videomicroscopy through closed cranial windows during basal conditions and during 2hours of reperfusion after global ischemia induced by 9minutes of asphyxia. Nitric oxide synthase(NOS) was inhibited by local window superfusion of L-nitroarginine(NA); superfusion of sodium nitroprusside(SNP) was used to donate NO. RESULTS: The mean number of adherent leukocytes to cerebral venules in the 9minutes asphyxia and 2hours reperfusion group were 161+/-19 compared with 13+/-4 in the nonasphyxial group. Superfusion of L-NA through the cranial window for 2hours resulted in leukocyte adherence similar to that observed during the initial 2hours of reperfusion after asphyxia. Leukocyte adherence was not additionally increased in asphyxic animal treated with L-NA. SNP inhibited asphyxia induced leukocyte adherence back to control levels. CONCLUSIONS: Nitric oxide inhibits leukocyte adherence to cerebral venules during the initial hours of reperfusion after asphyxia, and that NO supplementation inhibit asphyxia induced leukocyte adherence back to control levels. These results indicate that NO is an important factor in ischemia-reperfusion induced leukocyte adherence.

Down syndrome is associated with a large number of abnormal skin features including syringoma. Milia-like idiopathic calcinosis cutis is one of the rare dermatoses associated with Down syndrome. It has been reported in children with Down syndrome and clinically suggested as milia. The histological features show small nodular foci of calcium within the papillary dermis and transepidermal elimination of calcium deposits occasionally. We describe a 14-year-old female affected by Down syndrome, who had whitish papules on both the dorsal hands and feet and periorbital syringomas. Histopathological findings of the papule on the dorsal hand showed calcium deposits as amorphous, basophilic masses in the upper dermis and focal discharge of calcium by means of transepidermal elimination.

Dermatomyositis is a rare inflammatory myopathy with characteristic skin manifestations and muscular weakness. Vesicle or bulla formation in the dermatomyositis is rare and probably related to the presence of an internal malignant process. We report a case of dermatomyositis associated with esophageal cancer in a 72-year old man who had vesicles and bullae on his arms. He had erythema and edema on the face, chest, abdomen, back and legs for 20 days. Tense vesicles and bullae were found on his forearms and hands. Diagnosis of dermatomyositis was established by clinical manifestations, muscle enzyme study, electromyogram and histopathological findings of the skin. Adenocarcinoma of esophagus was found by gastroendoscopy. He was treated with total esophagectomy and topical steroid, but died of pneumonia and septicemia.
