Background/Aims: We aimed to compare the outcomes of Helicobacter pylori eradication in patients receiving sequential therapy (ST) depending on the use of ecabet sodium (ES). Materials and Methods: Between January to December 2015, 176 patients randomly received either ST alone (n=72) or 10-day ES therapy combined with ST (n=104). After applying the exclusion criteria, 56 patients were finally assigned to the ST-only group and 84 to the ST with ES group. We retrospectively reviewed and analyzed the H. pylori eradication rate and adverse events between the two groups. Results: Among the 140 patients, 121 (86.4%) achieved successful H. pylori eradication and 24 (17.1%) had adverse events. Eradication was achieved in 50 patients (89.3%) in the ST-only group and in 71 patients (84.5%) in the ST with ES group (P=0.420). No significant difference in the incidence of adverse events was found between the ST-only and ST with ES groups (12.5% vs. 20.2%, respectively; P=0.234). However, the ST with ES group tended to have a higher prevalence of nausea or vomiting than the ST-only group (11.9% vs. 1.8%; P=0.050). Conclusions: ST showed a good H. pylori eradication rate without deteriorating the adverse events regardless of adding ES.

Autoimmune pancreatitis (AIP) is rarely associated with pancreatic pseudocysts. AIP-associated pseudocysts requiring drainage despite steroid therapy are rather rare. We report a case of AIP with an infected pseudocyst requiring drainage despite steroid therapy. A 68-year-old male was diagnosed with AIP via pancreatic imaging, a high serum immunoglobulin G4 level, and steroid responsiveness. The AIP was accompanied by a pancreatic pseudocyst. Steroid therapy was prescribed, but the pancreatic pseudocyst became aggravated during steroid tapering. Endoscopic ultrasonography-guided cyst drainage was required; the pseudocyst then became completely resolved.

Malignant lesion of the trachea predominantly results from direct spread of adjacent tumors, whereas primary tracheal malignancies are rarely observed. Tracheal tumors are usually diagnosed late on account of delayed specific symptoms: dyspnea, stridor, coughing and hemoptysis. Primary tracheal tumors, although very rare, may extend into the thyroid gland and present as a thyroid mass. Surgery, followed by adjuvant radiotherapy, is the treatment of choice. A case of primary tracheal cancer with thyroid invasion is reported, and a review of the literature is presented.

Acute disseminated encephalomyelitis (ADEM) and Guillain-$Barr{\acute{e}}$ syndrome (GBS) are both rare post-infectious neurological disorders. The co-existence of these conditions has often been reported despite of low incidence. We describe a 20-year-old male, who presented with acute flaccid paralysis and encephalopathy. The patient showed reversible MRI lesions suggesting ADEM. This case showed anti-GT1a IgG and anti-GM1 IgM antibodies positivity. We suggest that certain immunogenicity within central and peripheral nervous system may share a common autoimmune process during the disease course.

Objectives This study aims to assess the status quo of depression among Korean physicians and identify stressors and psychiatric assets related to it. Methods The questionnaire was designed to assess depression, stressors, burnout and psychiatric assets. 343 physicians were included in the analyses. Results Physician depression in Korea was found to be related to several daily life stressors and occupational stressors. It was also related to higher burnout and lower psychological assets. Physicians who reported workplace problems, familial problems, and mannerism were at higher risk of depression while who reported passion (in psychiatric assets) were at lower risk of depression. Conclusions This study identified factors affecting physician depression in Korea. Further research would benefit physicians and their patients by identifying and testing various, including personal and organizational, intervention methods.

Skeletal muscle metastasis of gastric cancer is extremely rare and is associated with various symptoms. Here, we report on a 60-year-old woman with right hip pain after excessive walking. Two years earlier, the patient had been treated for advanced gastric cancer (surgery, adjuvant chemotherapy). Upon magnetic resonance imaging, diffuse muscle swelling and high signal intensity were observed in T2-weighted images of the right hip muscle. However, the FDG uptake in the right gluteal muscles was not obviously increased. Pathological examination of muscle biopsy revealed metastatic adenocarcinoma of stomach origin. The patient was treated with chemotherapy, and the swelling and pain in the right hip are progressively improving.

We report a case of neurolymphomatosis of lumbosacral plexus. A 63-year-old man, who had no past history except for diabetes mellitus, complained of severe pain and weakness on left lower extremity. Idiopathic lumbosacral plexopathy was diagnosed by electromyography. There were no abnormal findings except for FDG-PET/CT and MRI. They showed high uptake and thickening lesion in sciatic nerve and sacral plexus. However, about 7 months later, mass like lesion in left thigh was detected by FDG-PET/CT and MRI. Also, multiple hypermetabolic lesions were found in brain. Through brain biopsy, diffuse large B-cell lymphoma was confirmed. When a patient with idiopathic lumbosacral plexopathy complains of severe pain, it is necessary to consider FDG-PET/CT and MRI to differentiate neurolymphomatosis, even in patients who have no past history of lymphoma before. Especially, if FDG-PET/CT and MRI show sciatic and/or lumbosacral plexus lesion, neurolymphomatosis of lumbosacral plexus should be considered.

The nose is a complex three-dimensional structure and represents a major aesthetic focus of the face. As a gold standard for nasal soft tissue reconstruction, the 'forehead flap' provides reconstructive surgeons a robust pedicle and large amount of tissue to reconstruct almost any defect. However, during this process, some hair can be unintentionally introduced to the nose. Accordingly, laser hair removal is sometimes needed, but blood circulation and flap survival should be carefully monitored. Despite careful evaluation, a third-degree burn occurred in our patient that required eight weeks to heal. Here, we report on a burn resulting from epilation conducted 2 weeks after forehead flap for nasal reconstruction.

Anemia commonly occurs in kidney transplantation (KT) recipients. Many factors such as viral infection, bleeding, erythropoietin deficiency, and immunosuppressants are the causes of chronic anemia in KT recipients. We report 2 cases who developed severe anemia caused by parvovirus B19 infection and were successfully treated with intravenous immunoglobulin in pediatric KT recipients.

Tracheal leiomyoma is a rare benign tumor, which is composed of transformed cells of mesenchymal origin. We describe a case in which digital tomosynthesis was useful to evaluate a tracheal tumor that was overlooked on initial chest radiographs.
