Non-Hodgkin's lymphoma rarely originates from bone, and even more infrequently from a vertebral body. Lymphoblastic lymphoma is a rare type of non-Hodgkin's lymphoma, and results from an abnormality in adaptive immune cells. A 27-year-old man presented with a two-month history of night sweats, weight loss, and severe back pain. Radiological studies demonstrated an osteolytic lesion compressing the subarachnoid space at the T11 level. Posterolateral fusion with decompression was performed and a pathologic examination confirmed lymphoblastic lymphoma of the B-cell precursor type. To our knowledge, this is the first report of solitary lymphoblastic lymphoma from B-cell precursors in of the thoracic spine. Herein, we discuss the presenting symptoms and the management of this rare case of lymphoblastic lymphoma.

BACKGROUND/AIMS: Superficial esophageal squamous cell carcinoma (SESCC) is being increasingly detected during screening endoscopy. Endoscopic submucosal dissection (ESD) allows for en bloc and histologically complete resection of lesions. This study assessed the technical feasibility and long-term outcomes of ESD for SESCCs. METHODS: Between January 2005 and August 2012, 27 patients with 28 SESCCs underwent ESD at Pusan National University Hospital. The en bloc and pathologically complete resection rates, complication (perforation and bleeding) rate, incidence of esophageal stricture after ESD, and overall and disease-specific survival rates were evaluated. RESULTS: The en bloc and pathologically complete resection rates were 93% and 83%, respectively. No significant bleeding occurred, and perforation with mediastinal emphysema was observed in two patients (7%). Post-ESD stricture occurred in two patients (7%) who had mucosal defects involving more than three-fourths of the esophageal circumference. During a mean follow-up of 23 months, local tumor recurrence was seen in two of four lesions with pathologically incomplete resection; one was treated by re-ESD, and the other was treated by surgical esophagectomy. The 5-year overall and disease-specific survival rates were 84% and 100%, respectively. CONCLUSIONS: ESD seems to be a feasible, effective curative treatment for SESCCs. All patients should be closely followed after ESD.

This study was to examine the actual conditions and contributing factors of absenteeism in manufacturing workers. Subjects were 1,184 workers employed in Taejon city and the observation period for absenteeism was 3 months (June to August), 1992. We obtained the following results. 1. Percentage of the absentees among the studied subjects were 21.1% in gross absence and 6.9% in sickness absence. Gross absence rate of subjects was 1.2% and sickness absence rate was 0.5%. 2. In the group of absentees, mean days of absence was 2.8 days and those of sickness was 4.4 days. Mean days of sickness absence due to injury was higher than that of illness, but the total days of sickness absence was high in extremity injuries, trunk injury, general fatigue, head injury, musculoskeletal problem in that order. 3. Variables contributing to the absence were job classification, education level, working hours per day, exposure of noxious factor, worker classification. 4. In the group of absentees, variables influencing the gross absence rate were working atmosphere, body mass index, working environment, working hours per day but those of the sickness absence were working hours per day, education level and working atmosphere.

This study was performed to compare the cadmium accumulation levels in kidney with urinary cadmium excretion levels according to the duration of cadmium exposure in rats. Total 120 male rats, 6 weeks of age, were administered 0.5 mg/day of Cd to subcutaneously, intraperitoneally and orally 6 times per week for 12 weeks. The animals were sacrificed in the 1st day of 2nd, 4th, 6th, 8th, 10th and 12th week after beginning of cadmium administrations. Body weight, hematologic values, enzyme activities, renal Cd levels, urinary Cd and proteins were calculated and each value was compared according to the Cd administration routers. The Cd accumulation levels in the kidney of rats increased remarkably for 6-8th weeks which were experimented and urinary Cd excretion levels and urinary protein levels showed the tendency of increasing with the Cd accumulations in kidneys, especially in the subcutaneous injected rats. On the other hand, there was a significant positive correlation among the total Cd administration, the Cd accumulation in the kidneys, the urinary Cd excretion and protein.

BACKGROUND: This study evaluated the clinical results of arthroscopically assisted single and double bundle tibial inlay reconstructions of an isolated posterior cruciate ligament (PCL) injury. METHODS: This study reviewed the data for 14 patients who underwent a single bundle tibial inlay PCL reconstruction (Group A) and 16 patients who underwent a double bundle tibial inlay PCL reconstruction (Group B) between August 1999 and August 2002. The mean follow-up period in groups A and B was 90.5 months and 64 months, respectively. RESULTS: The Lysholm knee scores in groups A and B increased from an average of 43.3 +/- 7.04 and 44.7 +/- 5.02 preoperatively to 88.1 +/- 7.32 and 88.7 +/- 9.11 points at the final follow-up, respectively. In group A, stress radiography using a Telos device showed that the preoperative mean side-to-side differences (SSDs) of 9.5 +/- 1.60 mm at 30degrees of flexion and 9.8 +/- 1.70 mm at 90degrees of flexion were improved to 2.8 +/- 1.19 mm and 3.0 +/- 1.1 mm, respectively. In group B, the preoperative SSDs of 10.4 +/- 1.50 mm at 30degrees of flexion and 10.7 +/- 1.60 mm at 90degrees of flexion improved to 2.7 +/- 1.15 mm and 2.6 +/- 0.49 mm, respectively. There was no significant difference in the clinical scores and radiologic findings between the two groups. CONCLUSIONS: Single bundle and double bundle PCL reconstructions using the tibial inlay technique give satisfactory clinical results in patients with an isolated PCL injury, and there are no significant differences in the clinical and radiological results between the two techniques. These results suggest that it is unnecessary to perform the more technically challenging double bundle reconstruction using the tibial inlay technique in an isolated PCL injury.

Patients with inflammatory bowel disease (IBD) are at risk for extraintestinal manifestations (EIM) over the course of their disease. As EIMs can involve nearly every organ, and strongly influence the quality of life, early recognition and adequate treatment are necessary to prevent severe morbidity and mortality in affected patients. Pyoderma gangrenosum is a highly severe and debilitating skin condition that occurs in 1% to 10% of ulcerative colitis (UC) patients. Thromboembolic events are also serious EIMs and usually present as deep vein thromboses in the legs or as pulmonary embolisms. A 19-year-old woman presented with bloody diarrhea lasting for 3 months and deep ulceration on the right foot. She was diagnosed with UC. The patient's skin lesions did not improve with intravenous corticosteroids and oral mesalazine. After she was started on infliximab, we observed rapid resolution of the skin lesions. She continued to complain of mild dyspnea while in the hospital. Computed tomography performed using the thromboembolism protocol revealed pulmonary thromboembolism and deep venous thrombosis. The patient underwent anticoagulant therapy with low-molecular-weight heparin, and her dyspnea gradually improved. Anticoagulation was continued with warfarin. It is rare for IBD patients to have multiple EIMs; however, this case demonstrates that multiple EIMs are a possible presentation in UC and underscores the importance of a meticulous clinical examination and adequate evaluation in the management of IBD patients presenting with EIMs.

Extraintestinal manifestation (EIM) of inflammatory bowel disease (IBD) is approximately 36%. Of genitourinary complications as an EIM of Crohn’s disease (CD), nephrolithiasis is the most common urinary complication in patients with CD. CD patients have been shown to have decreased urinary volume, pH, magnesium, and excretion of citrate, all of which are significant risk factors for nephrolithiasis. Genitourinary complications often occur in case of a severe longstanding disease and are associated with, the activity of bowel disease, especially in those who have undergone bowel surgery. As uncontrolled nephrolithiasis could impair renal function as well as adversely affect quality of life, proper monitoring, early detection, and prevention of the occurrence of urologic complications in CD is crucial. Few data are available about urolithiasis in patients with CD. Herein we report a case of a successful removal of a 2.7 cm calcium oxalate stone using percutaneous nephrolithotomy from a patient with long-standing CD with a previous surgery for small intestinal and colonic stricture.

Fibrovascular polyps are rare benign intraluminal tumors that usually arise from the cervical esophagus. These often present as very large sized pedunculated polyps and cause symptoms including dysphagia and respiratory distress. Generally, large polyps are surgically excised, while endoscopic resection is limited to smaller polyps. Herein, we present a giant fibrovascular polyp of the esophagus treated successfully by endoscopic resection.

Intraductal papillary mucinous neoplasm of the bile duct (IPMN-B) is frequently found and has recently been recognized as a precancerous lesion leading to invasive carcinoma characterized by papillary growth of the ductal epithelium with rich mucin production and cystic dilatation of the hepatic duct. Surgical resection is the treatment of choice to avoid malignant transformation. Despite a growing number of studies on IPMN-B, there are few reports of its treatment aside from surgery. A 75-year-old woman was incidentally diagnosed as IPMN-B. Considering the patient's age, comorbidity, and preference, we recommended an argon plasma coagulation (APC) as local ablation therapy rather than surgical resection. There was no evidence of remnant tumor on percutaneous transhepatic cholangioscopy 4 weeks after the ablation of tumor mass by using APC. We report a rare case of IPMN-B successfully treated with APC.
