Eosinophilic colitis is a chronic inflammatory bowel condition of unknown etiology and a rare subtype of eosinophilic gastrointestinal diseases. It is characterized by gastrointestinal symptoms and increased eosinophil numbers in the intestinal mucosa and absence of other potential causes of gastrointestinal eosinophilia. The clinical presentation is varied and depends on the involved layer of the large intestine. There are no confirmatory laboratory tests, and the morphologic evaluation of biopsies or surgical specimens is required to confirm the diagnosis. A 65-year-old man presented with an 8 day duration of bloody diarrhea and lower abdominal pain. The patient was diagnosed with eosinophilic colitis by histopathological evaluation of biopsies and was further categorized as a nonatopic variant associated with non-IgE-mediated reaction. The patient was successfully treated with systemic corticosteroid for 2 weeks. On follow-up after 9 months, the patient remained well without relapse or new lesions.

OBJECTIVE: To evaluate the influences of age and height on pulmonary function in cervical spinal cord injury patients and to suggest the reference value of Pulmonary Function Test (PFT) with respect to each level of injury. METHOD: One hundred eighteen subjects with complete cervical spinal cord injury underwent PFT. Forced Vital Capacity (FVC) and Forced Expiratory Volume in 1 second (FEV1) were measured and percentages of normal predictive values were also calculated. RESULTS: Age, height and injury level were determinants of FVC and FEV1. But only injury level affected the percen-tages of FVC and FEV1 predictive values. The mean FVC of C4, C5, C6, C7, C8 tetraplegic subjects were 1.78 L, 2.00 L, 2.20 L, 2.74 L, 2.94 L respectively. The mean FEV1 of C4, C5, C6, C7, C8 tetraplegic subjects were 1.64 L, 1.83 L, 2.08 L, 2.59 L, 2.74 L respectively. CONCLUSION: Age and height should be considered when interpreting PFT of tetraplegic patients. The reference values suggested would help to evaluate the severity of pulmonary function loss in complete cervical spinal cord injury patients.

Targetoid hemosiderotic nevus (THN) is a rare variant of melanocytic nevus, characterized by a sudden development of a targetoid ecchymotic halo around a pre-existing nevus. THN clinically raises concern for malignant transformation due to its abrupt change in color and size. THN should be distinguished from other diseases showing a peripheral halo, including targetoid hemosiderotic hemangioma, halo nevus, and Meyerson nevus. Dermoscopy can help clinicians to differentiate THN from these diseases. The typical dermoscopic features of THN are known to be divided into two distinctive areas: the central melanocytic area and the peripheral ecchymotic area. In our case, dermoscopy revealed a novel bull’s eye pattern composed of a central area with characteristic features of benign melanocytic nevus, an intermediated white circular ring, and a peripheral milky red area. When a sudden change occurs in a pre-existing nodule showing targetoid features, dermoscopy should be considered before conducting a biopsy or surgical intervention.

Daylight Saving Time (DST) is used worldwide and affects millions of people annually. In the most countries, DST begins turning clocks forward by an hour in the spring and backward by an hour in the fall. transition out of DST in the fall increases the available daylight in the morning by one hour. Springtime transition into DST leads to an increase of the available daylight in the evening. During World War I, in an effort to reduce fuel consumption, Germany and England began to practice DST in 1916. Currently, 77 countries and most of OECD adopted DST except Korea, Japan, Iceland. The rationale for Daylight Saving Time (DST) is bolstered by the fact that it increases daylight hours within which the activity a population reaches its peak. Therefore, the effects of transitions into DST to the public health should be further explored, as DST affects millions of people annually and its impacts are still largely unknown. A general perception is that Turning clock forwards (on spring) or backwards (on fall) by one hour would affect our health. In This study, the association between Daylight Saving Time (DST) and health in population was investigated through theoretical and systemic review studies. Since the study was conducted solely on theoretical grounds, further research is needed to assess additional health-related impacts of Daylight Saving Time (DST) and to carry out more specific analysis on population health in Korea. In conclusion, population health is more strongly affected during spring transition into DST than during fall transition out of DST.

BACKGROUND AND OBJECTIVES: Carotid artery stenting has evolved as a potential alternative to carotid endarterectomy in patients (pts) with significant carotid artery stenosis. We evaluated the feasibility and long-term outcome of carotid artery stenting in selected pts at high surgical risk. MATERIALS AND METHODS: Between May, 1996 and September 1998 we performed carotid artery stenting at 35 lesions in 25 pts. There were 23 males and 2 fe-males. Mean age was 63.2+/-6.6 (range 54 - 77). Eight four percent (21/25) of the pts had significant coronary artery disease. Sixty four percent (16/25) of the pts had significant peripheral artery lesions. Sixty percent (15/25) of the pts had neurologic symptoms or non-disabling stroke. We used Wallstent in 32 lesions and Palmaz stent in 3 lesions. Carotid stenting was undertaken in 33 internal carotid, 1 common carotid and 1 external carotid lesions. Bil-ateral carotid stenting was undertaken in forty percent (10/25) of the pts. RESULTS: Carotid stenting was successful in all lesions. One patient died due to massive cerebral hemorrhage 3 days after carotid stenting, who had und-erwent stenting as a rescue procedure for failed endarterectomy. One major stroke developed during procedure with partial recovery. For the combined endpoint of strokes and death within 30 days of procedure, the incidence was 8% and 5.7% in terms of pts and procedures, respectively. On follow-up (12+/-7 months), we found neither neurologic complications nor death. Angiographic and/or duplex sonography which were performed at 5.5 month in all (18) eligible pts with 24 lesions revealed no evidence of stent deformity or restenosis ( 50% of diameter stenosis). Mean angiographic stenosis was 20% on follow-up angiography. CONCLUSION: Carotid artery stenting can be performed with high success and low complication rate in pts with significant carotid artery stenosis especially at high surgical risk. Follow-up clinical outcome of average 12 month was good with low restenosis rate.

The authors conducted a clinical observation of 55 cases of solitary pulmonary nodules at Yeungnam University Hospital from June 1986 to October 1990, and the following results were obtained: 1. The age distribution was ranged from 18 to 77 years, and the male-to female ratio was 1.8:1. 2. Among 55 cases of nodules, 28 cases were benign and 27 cases were malignant nodules, and of malignant nodules, the primary lung cancer was 23 cases and of benign nodules, 18 cases were tuberculoma. 3. 23 cases (41.8%) was asymptomatic and the other 32 cases were symptomatic; chest pain 12 cases, hemoptysis; 8 cases, cough; 8 cases and dyspnea; 4 cases. 4. The non-smoker-to-smoker ratio was 1:1.04, but among 23 smoker over 20 pack years, 14 cases were malignant nodules. 5. According to nodular size, there is no striking differences between benign and malignant nodules except 3-4 cm sized nodules. 6. The lobar distribution of nodules, 35 cases were in the right lung (upper lobe; 14 cases, middle lobe; 11 cases, and lower lobe; 10 cases) and 23 cases were in the left lung (upper lobe; 9 cases, lower lobe; 11 cases), and the malignant nodules were most commonly observed in the right upper lung.

BACKGROUND/AIMS: This study evaluated the efficacy of endoscopic treatment in a bile leak that occurred through various causes. METHODS: The medical records of 35 patients (mean age 55.4 years; male/female 25/10), who were diagnosed with a bile leak by endoscopic retrograde cholangiopancreatography in Yeungnam University Hospital from January 1998 to January 2006, were reviewed. RESULTS: The most common cause of the bile leak was an open cholecystectomy (n=13, 37.1%) followed by a laparoscopic cholecystectomy (n=10, 28.6%), trauma (n=2, 5.7%), transarterial chemoembolization (n=3, 8.6%), spontaneous (n=3, 8.6%), and a hepatic resection (n=4, 11.4%). Thirty-four patients were treated endoscopically by the insertion of a plastic stent with/without a sphincterotomy (70.6%, 24/34), a nasobiliary drainage (11.8%, 4/34), or a sphincterotomy alone (17.6%, 6/34). Of these 34 patients, 30 were cured by the endoscopic treatment, 2 patients died from liver failure despite the use of nasobiliary drainage and 2 patients did not improve after endoscopic treatment. One patient underwent surgery without endoscopic treatment because of a transsection of the common bile duct. With the exception of the two who died from liver failure, the overall cure rate of endoscopic treatment was 90.9% (30/33). There were no complications associated with the endoscopic treatment. CONCLUSIONS: Endoscopic treatment for a bile leak is safe and effective regardless of the cause.

The cardiovascular manifestations of hyperthyroidism are sinus tachycardia, paroxysmal supraventricular tachycardia, atrial fibrillation, atrial flutter, atrioventricular block, bundle branch block, angina pectoris, heart failure, and cardiomyopathy. Though complete atrioventricular block is rare, it is important to recognize it in clinical practice because of the possibility of cardiac arrest. We experienced a 47-year-old female patient who had hyperthyroidism with complete atrioventricular block and developed cardiac arrest despite the initiation of an antithyroid drug. We could resuscitate successfully and inserted a temporary pacemaker, but eventually a permanent pacemaker was needed to prevent the recurrence of cardiac arrest. We report a rare case of complete atrioventricular block and cardiac arrest associated with hyperthyroidism with the review of references.

Neurilemmoma, also refired to as Schwannoma, neurinoma and perineural fibroblastoma, is well capsulated solitary tumor of Schwann cell origin. The most common sites for benign solitary neurilemmoma are the extremities or the head and neck region. In the retroperitoneum, they are commonly seen in the presacral region. It is incidentally detected and confirmed by pathologic findings. We report a case of retroperitoneal neurilemmoma arising from adjacent to kidney, in 49 years old man.

PURPOSE: We evaluated the differences between radiologically measured size and pathologic size of renal tumors. MATERIALS AND METHODS: The data from 171 patients who underwent radical or partial nephrectomy for a renal tumor at Ajou University Hospital were reviewed. Radiologic tumor size, which was defined as the largest diameter on a computed tomographic scan, was compared with pathologic tumor size, which was defined as the largest diameter on gross pathologic examination. RESULTS: Mean radiologic size was significantly larger than mean pathologic size for all tumors (p=0.019). When stratified according to radiologic size range, mean radiologic size was significantly larger than mean pathologic size for tumors <4 cm (p=0.003), but there was no significant difference between the sizes for tumors 4-7 cm and >7 cm. When classified according to histologic subtype, mean radiologic size was significantly larger than mean pathologic size only in clear cell renal cell carcinomas (p=0.002). When classified according to tumor location, mean radiologic size was significantly larger than mean pathologic size in endophytic tumors (p=0.043) but not in exophytic tumors. When endophytic tumors were stratified according to radiologic size range, there was a significant difference between the mean radiologic and pathologic sizes for tumors <4 cm (p=0.001) but not for tumors 4-7 cm (p=0.073) and >7 cm (p=0.603). CONCLUSIONS: Our results suggest that in planning a nephron-sparing surgery for renal tumors, especially for endophytic tumors of less than 4 cm, the tumor size measured on a computed tomography scan should be readjusted to get a more precise estimate of the tumor size.
