  • In general, gastroesophageal reflux disease (GERD) is diagnosed clinically based on typical symptoms and/or response to proton pump inhibitor treatment. Upper gastrointestinal endoscopy is reserved for patients presenting with alarm symptoms, such as dysphagia, odynophagia, significant weight loss, gastrointestinal bleeding, or anorexia; those who meet the criteria for Barrett's esophagus screening; those who report a lack or partial response to proton pump inhibitor treatment; and those with prior endoscopic or surgical anti-reflux interventions. Newer endoscopic techniques are primarily used to increase diagnostic yield and provide an alternative to medical or surgical treatment for GERD. The available endoscopic modalities for the diagnosis of GERD include conventional endoscopy with white-light imaging, high-resolution and high-magnification endoscopy, chromoendoscopy, image-enhanced endoscopy (narrow-band imaging, I- SCAN, flexible spectral imaging color enhancement, blue laser imaging, and linked color imaging), and confocal laser endomicroscopy. Endoscopic techniques for treating GERD include esophageal radiofrequency energy delivery/Stretta procedure, transoral incisionless fundoplication, and endoscopic full-thickness plication. Other novel techniques include anti-reflux mucosectomy, peroral endoscopic cardiac constriction, endoscopic submucosal dissection, and endoscopic band ligation. Currently, many of the new endoscopic techniques are not widely available, and their use is limited to centers of excellence.

  • Purpose: To report the clinical results of two cases of coronoid process fractures that were treated with volar plating through a medial approach. Materials and Methods: Two fractures of the coronoid process that needed to be fixed were managed with open reduction and internal fixation through a medial approach using 2.4 mm locking compression plates (Compact Hand set$^{(R)}$, Synthes, Switzerland). The patients were followed up for 14 months and 17 months and were evaluated using the Mayo Elbow Performance Score (MEPS). Results: The MEPS was 95 for Case 1 and 100 for Case 2. Active elbow joint motions were $5^{\circ}-120^{\circ}$ (Case 1) and $0^{\circ}-130^{\circ}$ (Case 2). Supination and pronation fully recovered. Conclusion: Satisfactory results can be obtained in cases of coronoid process fractures because volar plating through a medial approach allows sound fixation and early mobilization of the elbow joint.

  • Surgical procedures on the trachea have only been undertaken within the past 50 years. Knowing the unique blood supply of the trachea and how to reduce tension on any anastomosis are key to a successful outcome. Tracheal conditions requiring surgery usually present with shortness of breath on exertion, and preoperative evaluation involves computed tomography and rigid bronchoscopy. Tracheal resection and reconstruction can be safely performed with excellent outcomes by following a well-described technique.

  • Copolymerization of glycidyl methacrylate(GMA) with methyl acrylate(MA) and the reaction of the copoly mer with primary amines were investigated. The monomer reactivity ratios were determined by Mayo-Lewis intersecting method. $r_1=0.22{\pm}0.03(GMA),\;r_2=0.50{\pm}0.07(MA)$. GMA and MA copolymerized to afford the polymer having good alternate arrangements of the units of the monomers.

  • This paper discusses the strategic concepts applied to integrated delivery system(IDS). IDS is rooted in vertical integration(VI) and strategic alliance(SA), but only few knows about the theoretical backbone of the IDS. The paper explains how VI and SA applies to IDS, then provides cases of IDS rooted in strategic concepts; Kaiser Permanante Model, Mayo Clinic Model, and ACO(Accountable Care Organizations). Finally the paper provides the implication of IDS on Korean healthcare delivery system.

  • Eosinophil degranulation plays a crucial role in tissue inflammatory reactions associated with helminth parasitic infections and allergic diseases. Paragonimus westermani, a lung fluke causing human paragonimiasis, secretes a large amount of cysteine proteases, which are involved in nutrient uptake, tissue invasion, and modulation of hos's immune responses. There is, however, limited information about the response of eosinophils to direct stimulation by cysteine proteases (CP) secreted by P. westermani. In the present study, we tested whether degranulation and superoxide production from human eosinophils can be induced by stimulation of the 2 CP (27 kDa and 28 kDa) purified from excretory-secretory products (ESP) of P. westermani newly excysted metacercariae (PwNEM). A large quantity of eosinophil-derived neurotoxin (EDN) was detected in the culture supernatant when human eosinophils isolated from the peripheral blood were incubated with the purified 27 kDa CP. Furthermore, the 27 kDa CP induced superoxide anion production by eosinophils in time- and dose-dependent manners. In contrast, the purified 28 kDa CP did not induce superoxide production and degranulation. These findings suggest that the 27 kDa CP secreted by PwNEM induces superoxide production and degranulation of human eosinophils, which may be involved in eosinophil-mediated tissue inflammatory responses during the larval migration in human paragonimiasis.

  • A retrospective study was performed to report the case occurrence of cystic echinococcosis (CE) in three hospitals of north-eastern region in Punjab Province, Pakistan. We reviewed retrospectively the clinical records of patients in 4 hospitals which were diagnosed with CE during 2012-2017. A total of 198 cases, 82 (41.4%) male and 116 (58.6%) females were detected as CE. The most Highest incidence was revealed in${\ldots}$. 21-30 years-old group (24.2%) followed by 41-50 (22.7%), 31-40 (16.2%), 11-20 (13.6%), 51-60 (8.1%), below 10 (5.5%), over 71 (5.1%) and 61-70 year-old group (4.5%). CE was detected in various organs of infected individuals. However, most of CE cases were detected in the liver (47.4%) and lung (18.6%). The present study indicated that CE is more or less prevalent in surveyed areas and one of the most important public health problems in Punjab Province, Pakistan.

  • Background: We described a surgical method for osteosynthesis and reported the resultant strength after application of a PHILOS plate through the anterolateral approach for the treatment of fractures of the distal humerus. Methods: Between February 2010 and March 2012, open reduction and internal fixation operations with the PHILOS plate for treatment of fracture of the distal humerus were performed on a total of nine patients (five men, four women). The mean age was 40.8 years (range, 24-50 years), and the average follow-up period was 9.1 months (range, 6-15 months). Clinical evaluations were performed 6 months after the operation. Clinical assessment included determination of the range of motion of the elbow, the Mayo and Oxford elbow scores, and any postoperative complications. Results: Fracture union was noted in all patients, with an average period of 12.4 weeks. The average Mayo elbow and Oxford elbow scores were 87.2 (of a total of 100) and 43.3 (of a total of 48), respectively. For the postoperative range of motion of the elbow, all patients showed complete recovery to the preoperative range of motion. No other conditions, such as neurolepsis, plate breakage, or rotational deformity, were observed. Conclusions: Open reduction and internal fixation of distal humerus fractures with a PHILOS plating system via anterolateral approach can be effective. A high rate of union with good outcomes can be assumed.
