Background:
Korea recently established 70 emergency medical service areas. However, there are many concerns that medical resources for stroke could not be evenly distributed through the country. We aimed to compare the treatment quality and outcomes of acute stroke among the emergency medical service areas.
Methods:
This study analyzed the data of 28,800 patients admitted in 248 hospitals which participated in the 8th acute stroke quality assessment by Health Insurance Review and Assessment Service. Individual hospitals were regrouped into emergency service areas according to the address of the location. Assessment indicators and fatality were compared by the service areas. We defined the appropriate hospital by the performance of intravenous thrombolysis.
Results:
In seven service areas, there were no hospitals which received more than 10 stroke patients for 6 months. In nine service areas, there were no patients who underwent intravenous thrombolysis (IVT). Among 167 designated emergency medical centers, 50 hospitals (29.9%) responded that IVT was impossible 24 hours a day. There are 97 (39.1%) hospitals that meet the definitions of appropriate hospital. In 23 service areas (32.9%) had no appropriate or feasible hospitals. The fatality of service areas with stroke centers were 6.9% within 30 days and 15.6% within 1 year from stroke onset than those without stroke centers (7.7%, 16.9%, respectively).
Conclusions
There was a wide regional gap in the medical resource and the quality of treatments for acute stroke among emergency medical service areas in Korea. The poststroke fatality rate of the service areas which have stroke centers or appropriate hospitals were significantly low.

BACKGROUND: The objective of this paper was to describe a novel technique for improving the maintenance of nipple projection in primary nipple reconstruction by using acellular dermal matrix as a strut in one of three different configurations, according to the method of prior breast reconstruction. The struts were designed to best fill the different types of dead spaces in nipple reconstruction depending on the breast reconstruction method. METHODS: A total of 50 primary nipple reconstructions were performed between May 2012 and May 2015. The prior breast reconstruction methods were latissimus dorsi (LD) flap (28 cases), transverse rectus abdominis myocutaneous (TRAM) flap (10 cases), or tissue expander/implant (12 cases). The nipple reconstruction technique involved the use of local flaps, including the C-V flap or star flap. A 1×2-cm acellular dermal matrix was placed into the core with O-, I-, and L-shaped struts for prior LD, TRAM, and expander/implant methods, respectively. The projection of the reconstructed nipple was measured at the time of surgery and at 3, 6, and 9 months postoperatively. RESULTS: The nine-month average maintenance of nipple projection was 73.0%±9.67% for the LD flap group using an O-strut, 72.0%±11.53% for the TRAM flap group using an I-strut, and 69.0%±10.82% for the tissue expander/implant group using an L-strut. There were no cases of infection, wound dehiscence, or flap necrosis. CONCLUSIONS: The application of an acellular dermal matrix with a different kind of strut for each of 3 breast reconstruction methods is an effective addition to current techniques for improving the maintenance of long-term projection in primary nipple reconstruction.

BACKGROUND AND OBJECTIVES: MUC5AC and MUC5B are representative secretory mucin genes in the human airway, whose expressions are increased by a variety of inflammatory mediators. Betulinic acid, a naturally occurring pentacyclic triterpenoid, is known to have an anti-inflammatory property. However, the effects of betulinic acid on mucin secretion of airway epithelial cells still have not been reported. Therefore, in this study, the effect of betulinic acid on inflammatory mediators-induced MUC5AC and MUC5B expressions was investigated in human airway epithelial cells. SUBJECTS AND METHOD: In the mucin-producing human NCI-H292 airway epithelial cells, the effects of betulinic acid on interleukin-1beta (IL-1beta)-, lipopolysaccharide (LPS)-, and phorbol myristate acetate (PMA)-induced MUC5AC and MUC5B expressions were analyzed by reverse transcription-polymerase chain reaction and enzyme-linked immunosorbent assay. RESULTS: Betulinic acid attenuated IL-1beta-, LPS-, and PMA-induced MUC5B mRNA and glycoprotein expression in NCI-H292 cells. On the other hand, betulinic acid did not attenuate IL-1beta-, and LPS-, but induced PMA-induced MUC5AC mRNA and glycoprotein expressions in NCI-H292 cells. CONCLUSION: These results suggest that betulinic acid attenuates IL-1beta-, LPS-, and PMA-induced MUC5B expression in the airway epithelial cells. Therefore, betulinic acid may modulate a control of mucus-hypersecretion in airway inflammatory diseases.

BACKGROUND AND OBJECTIVES: Roflumilast, a selective inhibitor of phosphodiesterase type 4, has an anti-inflammatory property. It has been used in the treatment of chronic inflammatory airway diseases such as chronic obstructive pulmonary disease and asthma. However, the effect of roflumilast on mucus secretion in inflammatory airway epithelial cells has not been reported. Therefore, this study was aimed at investigating the effects of roflumilast on the inflammatory mediator-induced MUC5AC and MUC5B expression in human airway epithelial cells. MATERIALS AND METHOD: In human mucin-producing NCI-H292 airway epithelial cells and primary cultures of nasal epithelial cells, the effects of roflumilast on lipopolysaccharide (LPS)- and phorbl-12-myrsitate-13-acetate (PMA)-induced MUC5AC and MUC5B expression were analyzed by reverse transcription polymerase chain reaction and enzyme-linked immunosorbent assay. RESULTS: Roflumilast attenuated LPS-induced MUC5AC and MUC5B mRNA and glycoprotein expression in NCI-H292 cells. And roflumilast attenuated PMA-induced MUC5AC and MUC5B mRNA and glycoprotein expression in NCI-H292 cells. In addition, roflumilast attenuated LPS and PMA-induced MUC5AC and MUC5B mRNA expression in the primary cultures of nasal epithelial cells. CONCLUSION: These results suggest that roflumilast attenuates MUC5AC and MUC5B expressions in airway epithelial cells. Roflumilast may be a potentially ideal therapeutic agent for the control of mucus-hypersecretion in treating chronic inflammatory airway diseases.

BACKGROUND AND OBJECTIVES: Naringenin and delphinidin are types of anthocyanidin, which are flavonoids and thus have anti-inflammatory property. Moderate consumption of natural dietary naringenin and delphinidin is believed to do anti-inflammatory action, but the action mechanism is unclear. Therefore, this study aimed to investigate the effects of naringenin and delphinidin on interleukin-1beta (IL-1beta)- and lipopolysaccharide (LPS)-induced MUC5AC and MUC5B expressions in airway epithelial cells. MATERIALS AND METHOD: In NCI-H292 cells and cultured nasal polyp epithelial cells, the effects of naringenin and delphinidin on IL-1beta- and LPS-induced MUC5AC and MUC5B expressions were analyzed by real-time polymerase chain reaction and enzyme-linked immunosorbent assay. RESULTS: Delphinidin attenuated IL-1beta- and LPS-induced MUC5AC and MUC5B mRNA and glycoprotein expression in a dose-dependent pattern in NCI-H292 cells and in cultured nasal polyp epithelial cells. Naringenin partially attenuated IL-1beta- and LPS-induced MUC5AC and MUC5B mRNA and glycoprotein expression at a high dose. CONCLUSION: These results suggest that delphinidin attenuates MUC5AC and MUC5B expressions in the airway epithelial cells. Between anthocyanidin and delphinidin, delphinidin exhibits greater potential as an ideal therapeutic agent for the control of mucus-hypersecretion in the treatment of airway inflammatory diseases.

A 53-year-old woman was diagnosed with gastrointestinal stromal tumor (GIST) of the stomach. Computed tomography (CT) revealed a huge mass (12 cm in diameter), likely to invade pancreas and spleen. In the operation field, the tumor was in an unresectable state. The patient was then started on imatinib therapy for 4 months. On follow-up imaging studies, the tumor almost disappeared. We performed total gastrectomy and splenectomy upon which two small-sized residual tumors were found on microscopy. In this paper, we describe a case of clinicopathologic change in unresectable GIST after neoadjuvant imatinib mesylate.

The greatest advantage of endoscopic submucosal dissection (ESD) in the stomach is that it can be used to perform en bloc resection of a large gastric neoplasm. However, ESD is more technically difficult and more commonly associated with prolonged procedure time and complications than conventional endoscopic mucosal resection. Until now, only a few reports have considered aspiration pneumonia after ESD, which is rare, but can be fatal. We experienced two cases of aspiration pneumonia after ESD with a gastric neoplasm. One was treated by intensive care with mechanical ventilation, and the other by antibiotics only. Prevention is thought to be important for aspiration pneumonia after ESD; therefore, patients at high risk for aspiration pneumonia are urged to take precautions. We considered various factors contributing to aspiration under endoscopy, such as local pharyngeal anesthesia, procedural time, and bleeding.

A 54 year old man was referred to our hospital with gastric cancer. The patient had a history of splenectomy and a left nephrectomy as a result of a traffic accident 15 years earlier. The endoscopic findings were advanced gastric cancer at the lower body of the stomach. Abdominal ultrasonography (USG) and magnetic resonance imaging demonstrated a metastatic nodule in the S2 segment of the liver. Eventually, the clinical stage was determined to be cT2cN1cM1 and a radical distal gastrectomy, lateral segmentectomy of the liver were performed. The histopathology findings confirmed the diagnosis of intrahepatic splenosis, omental splenosis. Hepatic splenosis is not rare in patients with a history of splenic trauma or splenectomy. Nevertheless, this is the first report describing a patient with gastric cancer and intrahepatic splenosis that was misinterpreted as a liver metastatic nodule. Intra-operative USG guided fine needle aspiration should be considered to avoid unnecessary liver resections in patients with a suspicious hepatic metastasis.

BACKGROUND AND OBJECTIVES: Recently, obesity has become one of the major health problems in our society. To overcome this problem, keeping a balance between food intake and energy expenditure is very important. Many natural substances including essential oils have been suggested for their potential effect on reducing weight. This study was performed to evaluate whether aroma inhalation of essential oil has a role in appetite regulation and works on the central nervous system through the olfactory stimulus. MATERIALS AND METHOD: Food intake was measured after 30 minutes of treatment with essential oil in overnight fasted Sprague-Dawley rats. In the control group, saline was used instead of essential oil. Changes in pro-opiomelanocortin (POMC) and neuropeptide Y (NPY) mRNA expression levels in the hypothalamus were measured following 30 minutes of treatment with geranium essential oil using real-time polymerase chain reaction. RESULTS: Of the seven essential oils, geranium significantly decreased the amount of food intake compared to the control group. Geranium essential oil significantly increased POMC mRNA expression in the hypothalamus, but did not change the NPY mRNA expression. The increased POMC mRNA expression was reversed by treatment with xylocaine, which blocks the olfactory perception. CONCLUSION: These results suggest that geranium essential oil has anorexic effect through the activation of POMC neurons in the hypothalamus via olfactory stimulus.

PURPOSE: Since skin sparing mastectomy removes the mammary gland and the nipple-areolar complex preserving all mammary skin, it makes the widespread use of implants in immediate reconstruction. This article reports our experience in immediate breast reconstruction after skin sparing mastectomy by using the silicone implants in patients especially who have small to moderate sized and minimal ptotic breast. METHODS: From September of 2007 to July of 2009, we performed breast reconstruction for 44 breasts of 40 women with silicone implant after mastectomy. Tumors were divided into 5 malignant types (21 IDC, 18 DCIS, 2 ILC, 2 phylloides tumor, 1 mucinous carcinoma). The implant is placed in a submuscular pocket or in a submuscular-subfascial pocket depending upon the condition of the muscles and skin flaps after mastectomy. RESULTS: The mean age was 47 years and the average follow-up period was 11 months. Cosmetic outcome was assessed by evaluation of photographs and assessment of breast volume and shape, breast symmetry, and overall outcome. About 80% of each of these parameters was scored as good or excellent. Breast complication was developed in a total of 6 cases including 2 capsular contracture, 2 partial skin necrosis due to blue dye injection and 2 implant infection. CONCLUSION: The use of definitive implants in a skin sparing mastectomy is a one-stage immediate breast reconstruction with low morbidity and acceptable result. This method is considered reliable with favorable aesthetic result.
