The incidence of heterotopic gastric mucosa located in the submucosa in resected stomach specimens has been reported to be 3.0 to 20.1%. Heterotopic gastric mucosa is thought to be a benign disease, which rarely becomes malignant. Heterotopic gastric mucosa exists in the gastric submucosa, and gastric cancer rarely occurs in heterotopic gastric mucosa. Since tumors are located in the normal submucosa, they appear as submucosal tumors during endoscopy, and are diagnosed through endoscopic biopsies with some difficulty. For such reasons, heterotopic gastric mucosa is mistaken as gastric submucosal tumor. Recently, two cases of early gastric cancer arising from heterotopic gastric mucosa in the gastric submucosa were treated. Both cases were diagnosed as submucosal tumors based on upper gastrointestinal endoscopy, endoscopic ultrasound, and computed tomography findings, and in both cases, laparoscopic wedge resections were performed, the surgical findings of which also suggested submucosal tumors. However, pathologic assessment of the surgical specimens led to the diagnosis of well-differentiated intramucosal adenocarcinoma arising from heterotopic gastric mucosa in the gastric submucosa.

BACKGROUND: Maintenance of adequate vascular access for hemodialysis is important in patients with end-stage renal disease. Once arteriovenous fistula (AVF) occlusion occurs, the patient should be treated with rescue therapy. This study was performed to evaluate the results of a rescue therapy for AVF occlusion. METHODS: From January 2008 to December 2012, 47 patients who underwent surgical rescue therapy for AVF occlusion after graft AVF formation, were enrolled in this study. The patients were divided into two groups, namely the graft repair group (group A, n=19) and the thrombectomy group (group B, n=28). Postoperative results of both groups were analyzed retrospectively. RESULTS: There were no statistically significant differences in the clinical characteristics between the two groups. In terms of the duration of AVF patency after the first rescue therapy, group A showed a longer AVF patency duration than group B (24.5+/-21.9 months versus 17.7+/-13.6 months), but there was no statistically significant difference (p=0.310). In terms of the annual frequency of AVF occlusion after the rescue therapy of group A was lower than that of group B (0.59 versus 0.71), but there was no statistically significant difference (p=0.540). The AVF patency rates at 1, 2, 3, and 5 years after the first rescue therapy in group A were 52.6%, 31.5%, 21.0%, and 15.7%, respectively, and those in group B, they were 32.1%, 25.0%, 17.8%, and 7.14%, respectively. There was no statistically significant difference (p=0.402). CONCLUSION: Graft repair revealed comparable results. Although there was no statistically significant difference, the patent duration and annual frequency of AVF occlusion of group A were better than those of group B. Therefore, graft repair is considered as a safe and useful procedure for maintaining graft AVF.

OBJECTIVE: The purpose of this study was to determine, when measuring prostate volume by TRUS, whether height is more accurately determined by transaxial or midsagittal scanning. MATERIALS AND METHODS: Sixteen patients who between March 1995 and March 1998 underwent both preoperative TRUS and radical prostatectomy for prostate cancer were included in this study. Using prolate ellipse volume calculation (height x length x width x pi/6), TRUS prostate volume was determined, and was compared with the measured volume of the specimen. RESULTS: Prostate volume measured by TRUS, regardless of whether height was determined transaxially or midsagittally, correlated closely with real specimen volume. When height was measured in one of these planes, a paired t test revealed no significant difference between TRUS prostate volume and real specimen volume (p = .411 and p = .740, respectively), nor were there significant differences between the findings of transaxial and midsagittal scanning (p = .570). A paired sample test, however, indicated that TRUS prostate volumes determined transaxially showed a higher correlation coefficient (0.833) and a lower standard deviation (9.04) than those determined midsagittally (0.714 and 11.48, respectively). CONCLUSION: Prostate volume measured by TRUS closely correlates with real prostate volume. Furthermore, we suggest that when measuring prostate volume in this way, height is more accurately determined by transaxial than by midsagittal scanning.

OBJECTIVES: Narcolepsy with cataplexy is a rare chronic sleep disorder characterized by excessive daytime sleepiness, cataplexy, sleep paralysis, and hypnagogic/hypnopompic hallucinations. The aims of the present study were comparing the health-related quality of life (HR-QOL) of patients with type I and type II narcolepy patients, and determining the factors that influence the HR-QOL in narcolepsy patients. METHODS: All patients performed night polysomnography (PSG) and multiple sleep latency test (MSLT). HR-QOL and the severity of subjective symptoms were evaluated using various questionnaires, including the Korean versions of the Medical Outcome Study Short Form-36, the Pittsburg Sleep Quality Index-Korean version, the Korean version Epworth Sleepiness Scale, and the Korean version Beck Depression Inventory-2. RESULTS: We enrolled 21 type I narcolepsy patients and 27 type II patients. Type I patients had short rapid eye movement (REM) latency on night PSG and more sleep onset REM periods on MSLT. The total score of HR-QOL was worse in patients with type I narcolepsy than in the type II narcolepsy patients. There was association between the severities of excessive daytime sleepiness, depression and the degree of worsening of QOL. CSF hypocretin level had no correlation with the scores of HR-QOL. CONCLUSIONS: These findings demonstrate that type I narcolepsy patients are sleepier, depressive, and have more burden on the HR-QOL. And the impairment in QOL of narcolepsy patients is related to the degree of excessive daytime and depressive mood.

Methemoglobinemia is an uncommon but potentially fatal disorder. Most cases have no adverse clinical consequence and require no treatment, but methemoglobinemia is often overlooked as a cause of low oxygen saturation, and often mistaken for the more common causes of hypoxia by anesthesiologists despite simple bedside tests that indicate the presence of this treatable abnormality. We present a 68-year-old female patient who underwent gastrectomy for advanced gastric cancer with bleeding. In the preoperative period, the patient showed cyanosis and oxygen saturation was 85% by pulse oximeter, but oxygen saturation by arterial blood gas analysis was 100%. After tracheal intubation, the methemoglobin level was 18.3%. Ascorbic acid and methylene blue were administered. During preanesthetic evaluation, the patient had not informed the anesthesiologist that she had been taking dapsone.

PURPOSE: This study examined the results of treatment according to the stage and size of a spontaneous osteonecrosis lesion of the knee (SONK) in the patients over 60 years of age. MATERIALS AND METHODS: Twenty-two knees from 19 patients over 60 years of age were treated for spontaneous osteonecrosis of the knee at our institution between January, 2000, and June, 2004. The mean follow time was 20.7 months. The condylar ratios, proportion of the lesion size to the condyle were measured. The size was obtained by multiplying the values from the anteroposterior and lateral radiographs. The stages were classified radiographically, and the treatment results were analyzed according to the size and stage. Conservative treatment was performed if the ratio and size were <40% and 5.0 cm2, respectively. Arthroplasty was performed if the ratio or size was >40% or 5.0 cm2. A paired T-test, Spearman correlation test and Wilcoxon test were used for the statistical evaluation. RESULTS: There was a higher prevalence in females (15 patients, 79%), and the mean age was 65 years (46-77 years). Bilateral involvement was observed in 3 patients. The lesions involved mainly the medial femoral condyle (21 cases, 95%). Seven cases (31%) had a condylar ratio <40% and 15 cases (69%) had a condylar ratio >40%. Conservative treatments were performed in 5 cases staged radiographically as I or II and there were no significant changes in the knee scores (p=0.931). Of the 17 cases staged III and IV radiographically, conservative treatment and arthroplasty were performed in 7 and 10 cases, respectively. Seven cases, in whom conservative treatments had been performed, showed a decreased in the knee scores compared with the increased knee scores in 10 patients treated with arthroplasty (p=0.943). CONCLUSION: An accurate diagnosis and measurement of the size and staging of spontaneous osteonecrosis of knee in patients over 60 years of age is important for proper treatment. Clinically, no further progression of symptoms is visible on grade I and II spontaneous osteonecrosis of the knee after conservative treatment. However, arthroplasty improves the clinical results in patients with radiological grade III and IV osteonecrosis compared with conservative treatment.

PURPOSE: There is little information about the treatment of carpometacarpal (CMC) fracture-dislocations. The purpose of this study was to investigate treatment methods and times between diagnosis and surgery in CMC fracture-dislocations. MATERIALS AND METHODS: In 18 cases treated by surgery, the 4, 5th CMC joints were found to be the most frequently involved in 13 cases. Comminution of the carpal or metacarpal bone was present in 8 cases. The time to surgery was within 3 days in 10 patients, within 5 days in 6, within 9 days in one patient and more than 4 weeks in one. All the injuries were managed by closed reduction and K-wire fixation except for one which was detected after 4 weeks since initial trauma. RESULTS: A painless full hand function was restored in 13 cases. Intermittent pain was present in 5 cases in which there was comminution in 4. However, clinically full hand function was restored in 4 cases except for one in whom the treatment was delayed. CONCLUSION: If the treatment of CMC fracture-dislocation is not delayed a successful result can be gained using the closed method even though comminution occurs.

Hiccup can be regarded as a failure of the usual alternating excitation-inhibition between glottis closure and inspiration. The coordinating center is located in the brain-stem reticular formation. A wide variety of pathological conditions can cause intractable hiccup: myocardial infarction, brain tumor, renal failure, prostate cancer, abdominal surgery, etc. Stroke is an unusual cause of intractable hiccup. Intractable hiccup is rare but disabling condition which can induce depression, weight loss, sleep deprivation, and even death. Etiological treatment is not always available and intractable hiccup treatment has classically relied on metoclopramide and chlorpromazine. We experienced a case of intractable hiccup induced by multiple cerebral infarct, and we present this rare case with the review of literature.
