An aneurysm of the distal superior cerebellar artery (SCA) is a highly rare disease. Fusiform aneurysms of the distal SCA are particularly challenging to treat. Clipping, trapping with or without bypass using microsurgery or endovascular treatment (EVT) were used to treat this condition. We describe the case of fusiform distal SCA aneurysms treated successfully with endovascular coiling with a 3-month follow-up. A 39 year-old male was presented with subarachnoid hemorrhage (SAH) and a 15 mm fusiform aneurysm of the ambient segment of the left distal SCA. EVT for parent artery occlusion and packing of the aneurysm was done. Left sixth nerve palsy appeared after 1 day of EVT. The symptom completely recovered within 1 week of the post-procedural period. No neurological deficit was seen during the clinical 3-month follow-up. EVT of fusiform distal SCA aneurysms with coils is a safe and feasible option to manage this rare condition. However, the treatment options must be carefully selected depending on the neurologic condition, development of collateral circulation, and configuration of the dissection.

The advance of the immunobiology clarifies the nature of non-Hodgkin's lymphoma(NHL). In addition the proceed in the immunophenotyping renders the classification of NHL. According to the Revised European American Lymphoma(REAL) classification, classified by the etiologic factors, molecular biological characteristics, immunophenotype, cytogenetics and histologic feature, nasal T/NK-cell lymphoma(=angiocentric lymphoma) belongs to the category of peripheral T-cell and natural killer cell lymphoma. Nasal T/NK-cell lymphoma is a distinct clinicopathologic entity characterized by progressive necrotic lesions in the nasal cavity, nasopharynx, and palate. The cellular origin of this tumor has been controversial. Although most nasal T/NK-cell lymphomas are of NK-cell lineage, being CD56+, negative for surface CD3(Leu4), and unassociated with rearrangements of the T-cell receptor genes, other minor variants have been reported. This lymphoma is a rare disease and usually experienced in adult. Recently, we experienced a rare type lymphoma, nasal T/NK-cell lymphoma, in 14 years old boy. His soft mass occupied the right nasal cavity including the nasal septum and turbinate. Pathologically this nasal mass showed the infiltration into the vascular wall, illustrating angiodestructive lesion. The cellular origin was NK-cell lineage, being CD56+ and negative to CD3. Now, we report the case with a brief review of related literatures.

OBJECTIVE: This study analyzed retrospectively the bladder function of patients after early surgery for cauda equina syndrome (CES) performed within 24 or 48 hours, or after 48 hours of the onset of autonomic symptoms. METHODS: We retrospectively reviewed the clinical data of 31 patients after decompression surgery for lumbar disc herniation (LDH) who had been diagnosed with CES between January 2001 and December 2014 at Inha University Hospital. The following factors were assessed to evaluate the influence of time to surgery: bladder function, rectal incontinence, sexual dysfunction, LDH level, and degree of spinal canal compression. RESULTS: After decompression, the outcome group was categorized into normal bladder function and abnormal bladder function. The patients operated on within 48 hours showed an improved postoperative outcome. Among 16 patients operated on within 48 hours, 13 (81%) recovered normal bladder function. In contrast, among 15 patients with decompression after 48 hours, 6 (40%) recovered normal bladder function. Among 21 patients with mild bladder dysfunction at admission, 16 (76%) recovered normal bladder function after decompression. CONCLUSION: Our study suggests that patients who have decompression surgery within 48 hours of the onset of bladder dysfunction, improve their chances of recovering bladder function than those who have a late operation (>48 hours). Also, patients with mild bladder dysfunction are more likely to recover bladder function after decompression, than patients with severe bladder dysfunction.

OBJECTIVES: Few long-term studies have been conducted on the serotype and antibiotic resistance patterns of Salmonella speices (spp.) The aim of this study was to determine the serotypes and antibiotic resistance patterns of Salmonella spp. isolated at Jeollanam-do in Korea from 2004 to 2014. METHODS: A total of 276 Salmonella samples were evaluated. Serotyping was carried out according to the Kauffmann–White scheme. Antibiotic susceptibility was determined using the Vitek II system with an AST-N169 card. RESULTS: A total of 22 different serotypes were identified, and the major serotypes were Salmonella Enteritidis (116 strains, 42.0%) and Salmonella Typhimurium (60 strains, 21.7%). The highest resistance was observed in response to nalidixic acid (43.4%), followed by ampicillin (40.5%) and tetracycline (31.6%). Resistance to nalidixic acid was detected in 81.0% of S. Enteritidis. Multidrug resistance was detected in 43.3% of Salmonella spp. S. Enteritidis and S. Typhimurium presented the highest resistance (98.3%) and multidrug resistance rate (73.3%), respectively. The most highly observed antibiotic resistance pattern among Salmonella spp. in this study was ampicillin-chloramphenicol (14 strains, 5.7%). CONCLUSION: Overall, S. Enteritidis and S. Typhimurium showed higher antibiotic resistance than the other Salmonella serotypes tested in this study. Our study will provide useful information for investigating the sources of Salmonella infections, as well as selecting effective antibiotics for treatment.

After renal transplantation, we are more likely to encounter hyperkalemia rather than hypokalemia. We report a case of kidney transplantation recipient with hypokalemia and hypertension secondary to primary aldosteronism. A 48 year-old woman was presented with fatigue and weight loss that had lasted for 3 months. She was diagnosed as autosomal dominant polycystic kidney disease that ultimately progressed to end-stage renal disease. She was operated for renal transplantation before 6 months. She had hypokalemia and hypertension at that time. The ratio of plasma aldosterone over plasma renin activity was 851.7. The computed tomography (CT) revealed 2.4x1.7 cm sized adrenal mass on the right side. The pre-transplantation CT also showed that there had been adrenal mass in the same location even before the transplantation. Right adrenalectomy was performed. After she got discharged, she was again presented with nausea and vomiting. She developed hyperkalemia and was diagnosed as hyporeninemic hypoaldosteronism. She was prescribed with fludrocortisones and recovered from the disease, and resumed the state of normokalemia and normotension.

BACKGROUND/AIMS: We used high-resolution impedance manometry (HRIM) to determine the length of breaks on the isobaric contour which would predict incomplete bolus clearance in patients in the sitting position. METHODS: In total, 651 swallows in 71 patients with esophageal symptoms were studied using a solid-state HRIM system in the sitting position. Each swallow was classified as complete or incomplete bolus clearance by impedance criteria and peristaltic integrity was evaluated using 20- and 30-mmHg pressure topography isobaric contours. Correlations between the lengths of the breaks for 20- and 30-mmHg were analyzed. RESULTS: Complete bolus clearance was observed in 83.3% (542/651) of swallows. Breaks of 3 and 7 cm or less were associated with a bolus clearance of 96.8% on the 20-mmHg and 94.7% on the 30-mmHg isobaric contour, respectively (P < 0.001). The areas under the ROC curves for the 20 and 30 mmHg isobaric contours were 0.900 and 0.950, respectively. The sensitivity and specificity for complete bolus clearance were 75.6% and 89.3% for breaks 3 cm or less on the 20-mmHg isobaric contour and 87.9% and 78.7% for breaks 7 cm or less on the 30-mmHg contour (P < 0.001). CONCLUSIONS: Breaks of < 3 cm in the 20-mmHg isobaric contour or < 7 cm in the 30-mmHg isobaric contour were associated with com -plete bolus clearance. The threshold for breaks in the sitting position was greater than previous reports using the supine position and longer breaks predicted incomplete bolus clearance.

Secondary hyperparathyroidism is one of the most common complications of patients with chronic kidney disease (CKD). Mandibular enlargement, metastatic pulmonary calcification, and gastric mucosal calcinosis are rare complications in these patients. The defect of calcium and phosphorus metabolism may precipitate pathologic calcification at diverse organs and soft tissue, and change bone architecture. In case of involving periarticular area, patients usually present with localized swelling, pain, and reduced mobility in affected sites. However, in case of organ involvement, except in an advanced stage of disease, there are no specific symptoms. Among these patients, treatment strategies include tight control of calcium and phosphate levels, parathyroidectomy for hyperparathyroidism, renal transplantation, and local excision of calcific lesions. We report a case of mandibular enlargement, metastatic pulmonary calcification, and gastric mucosal calcinosis due to CKD with improvement 3 months after medical and surgical treatment.

FLT3 mutations are common genetic changes, and are reported to have prognostic significance in acute myeloid leukemia (AML). The FLT3 internal tandem duplication (ITD) and the D835 activating mutation in the tyrosine kinase domain (TKD) were analyzed by polymerase chain reaction (PCR) in the genomic DNA of Korean patients with AML at diagnosis and during follow-up. There were 226 patients with AML enrolled between March 1996 and August 2005. The incidence of ITD and TKD at diagnosis was 13% (29/226) and 3% (6/226). When compared to Western and other Asian patients with AML, Korean patients had a lower frequency by about two-thirds of ITD and TKD. Among the non-M3 cases (N=203), the patients with an ITD had a significantly shorter event-free survival when compared with those without an ITD (p=0.0079). Among 54 relapsed patients, 9 patients had the FLT3 ITD at diagnosis. Six patients demonstrated a reappearance of the ITD and 3 patients remained negative at relapse. One patient, among 45 patients who relapsed, had a negative baseline ITD but acquired a de novo ITD at relapse. There were 101 samples from 93 patients in remission; they were all negative for an ITD. Among 34 patients who failed to achieve a remission, five patients had a persistent ITD and one patient had a de novo ITD. These results support the concept of resistance of FLT3 ITD leukemic clones to chemotherapy. Therefore, effective therapy with FLT3 targeting agents may improve the prognosis of non-M3 AML patients with the FLT3 mutation.

BACKGROUND/AIMS: The efficacy and safety of a combination of ezetimibe and low-dose statin as primary treatment for dyslipidemia in renal transplant patients were evaluated prospectively. METHODS: The study enrolled 77 renal transplant recipients with dyslipidemia. They were given ezetimibe (10 mg) and simvastatin (10 mg) for 6 months as the initial treatment for dyslipidemia. Efficacy and safety were evaluated using lipid profiles, trough calcineurin inhibitor levels, allograft function, and adverse effects. The effects on proteinuria and high sensitivity C-reactive protein (hsCRP) levels were also evaluated. RESULTS: Ezetimibe and low-dose simvastatin significantly decreased the levels of total cholesterol (34.6%), triglyceride (16.0%), and low-density lipoprotein cholesterol (LDL-C) (47.6%), and 82.5% of the patients reached the target LDL-C level of <100 mg/dL. No significant change in the trough calcineurin inhibitor levels or allograft function occurred, and no serious adverse effects were observed. Fourteen patients (18.2%) discontinued treatment; eight patients (11.7%) developed muscle pain or weakness without an increase in creatinine kinase levels, and two patients (2.6%) developed elevated liver transaminase levels. The proteinuria and hsCRP levels did not change significantly. CONCLUSIONS: Ezetimibe and low-dose statin treatment is safe and effective as a primary treatment for dyslipidemia in renal transplant patients.

BACKGROUND: Boerhaave's syndrome is a spontaneous rupture of the esophagus. The classic symptom triad, vomiting, chest pain, and subcutaneous emphysema, rarely develop together. It is diagnosed by using plain chest film, an esophagogram with a water soluble contrast media, and computerized tomography, but it is somewhat difficult to make an early diagnosis. It is generally treated with a surgical procedure, but the most frequent complication is suture line leakage, which leads to a pyothorax, pneumonia, mediastinitis, and eventually an irreversible septic condition. METHODS: We retrospectively reviewed 10 cases of patients with spontaneous esophageal rupture treated by various surgical methods during the recent 6 years at the Department of Surgery and Internal Medicine, the Catholic University of Korea. RESULTS: The results of the clinical reviews are as follows: There were 9 males and 1 female, and the mean age was 53 years old. The main symptom was chest pain (70%), and that developed after severe vomiting in 6 cases (60%). Abnormal findings were revealed on the chest PA films of 6 cases. Esophagogram were used in 8 cases, and a combined chest CT in 5 cases. Seven (70%) received an operation in less than 24 hours after the attack and 3 cases after 72 hours. The lower one-third of the esophagus was perforated in 9 cases (90%), and the left side of the esophagus was perforated in 8 cases (80%). The methods of operation were primary repair (6 cases), an esophagectomy and esophagogastrostomy (3 cases), and a cardial ligation, proximal esophagostomy, gastrostomy, and feeding jejunostomy (1 case). Anastomosis leakage and empyema developed in each of 4 cases. The overall mortality rate was 20%; only two patients died due to a delayed hospital visit (surgery 72 hours after first attack of symptoms). CONCLUSIONS: We recommand that the most important factor affecting the prognosis for spontaneous rupture of the esophagus is early diagnosis and immediate surgical intervention.
