15 male patients who received total cystectomy with ileal conduit for bladder tumor were reviewed in relation to the incidence of urethral involvement. Of 15 patients six had recurrent transitional cell carcinoma in the urethral remnant among them one (1/15) received subsequent therapeutic urethrectomy and remaining 5 patients underwent delayed therapeutic urethrectomy after confirmation of urethral tumor but 9 of the 15 had only received total cystectomy. We concluded that the remaining urethra might constitute a potential hazard for further tumor formation. We believe that prophylactic urethrectomy is the way to prevent the recurrence of the malignancy who have multiple tumors, concurrent upper tract tumors, and involvement of the trigone or prostatic urethra.

We report a 36-year-old male with the bilateral visual field defect following LASIK was observed. Preoperatively, patient had high myopia(right. -7.25 0.75x18, left. -7.5-0.5x12), normal intraocular pressure(IOP)(right/left: 16/14 mmHg), normal visual field(Humphrey 30-2 visual field)and revealed the tilted discs with symetric optic nerve head cupping(cup-to-disc ratio, 0.70), parapapillary atrophy. Bilateral LASIK keratorefractive surgery was on the same day and intraoperative complication was not noted. After the first operative visit day, examination revealed uncorreted visual acuity right 0.8 and left 0.6 but scotoma was reported. Three months later, Humphrey 30-2 visual field revealed a near-superior altitudinal defect in the right eye and nasal side visual field defect in the left eye. Best corrected visual acuity was 1.0 in the right eye, 0.8 in the left eye. Repeated visual fields over a 11-month period postoperatively showed stability of the defect, with IOP of 12 mmHg to 15 mmHg in each eye. We considered LASIK uses a microkeratome vaccum ring to make a corneal flap, transient elevation of IOP alters the microcirculation of optic nerve head and may have precipitated visual field defect.

PURPOSE: This study was performed to find out the effects of lidocaine or 8.4% sodium bicarbonate mixed with rocuronium on mean arterial pressure, heart rate and withdrawal movement. METHODS: Data collection was performed from December 15, 2006 through May 31, 2007. Seventy-five patients with American Society Anesthesiologist (ASA) physical status I & II, under general anesthesia, were randomly assigned to 1 of 3 groups: R group (RG) received rocuronium 0.6 mg/kg; RL group (RLG), rocuronium 0.6 mg/kg mixed with 2 mL of 2% lidocaine; RS group (RSG), rocuronium 0.6 mg/kg with the same volume of 8.4% sodium bicarbonate. Mean arterial pressure, heart rate and withdrawal movement were observed from its injection until 5 min after endotracheal intubation. RESULTS: The incidence of withdrawal movement with its corresponding injections was 72%, 40% and 4% in RG, RLG and RSG, respectively (p<.001). Score of withdrawal movement was the lowest in RSG of all groups (p<.001). While mean arterial pressure (p=.011) in RSG decreased significantly, and heart rate (p=.003) in RG increased more with its injection than before induction of anesthesia. CONCLUSION: Administration of the equivalent volume of 8.4% sodium bicarbonate with rocuronium is more effective than that of lidocaine with rocuronium compared with rocuronium only, in preventing withdrawal movement and in stabilizing mean arterial pressure and heart rate.

Being described first 1912 by Hashimoto, Chronic lymphocytic thyroiditis has been most commonly diagnosed as inflammatory thyroid disease. Despite of worldwide reports about the concomitant malignancy with Hashimoto's thyroiditis, the definite incidence of coexsiting malignancy and the etiologic relationship between these different pathologic conditions remains to be brought out. Analyzing 18 cases of coexisting thyroid carcinoma among 80 cases of Hashimoto's thyroiditis, confirmed by pathologic study at Presbyterian medical center in Chonju between 1991 and 1995, the authors intended to make guideline of management for them. The results are as follows: 1. The incidence of coexisting carcinoma with HT was 18/80(22.5%). 2. The average age of patients with coexisting carcinoma was 44.1 years and all of them were female.3. Cold nodules on thyroid scan were noticed in 23 cases(22.7%) of HT and 7 cases(33.8%) of coexisting carcinoma with HT. 4. Calcified lesions on thyroid sonography were detected in 0 cases of HT and 4 cases(50%) of coexisting carcinoma. 5. The pathologic types of carcinoma were papillary(17/18, 94.4%) and follicular(1/18, 5.6%). 6. 3 cases of coexisting carcinoma had metastatic lesions on peritracheal lymph nodes and another 3 cases had on ipsilateral jugular nodes. 7. The carcinoma of smaller than 0.5cm were 7 cases, of 0.6-1.0cm were 3 cases, of 1.1-1.5cm were 5 cases, and so 15 cases(83.3%) were occult carcinoma. Only 3 cases were larger than 1.6cm. 8. Coexisting carcinoma patients with HT underwent subtotal thyroidectomy (4 cases), subtotal thyroidectomy & anterior compartment dissection (ACD, 6 cases), subtotal thyroidectomy & modified RND (2 cases), thyroid lobectomy & ACD (4 cases), thyroid lobectomy & modified RND (1 cases), or near total thyroidectomy & ACD (1 case).

We reviewed 48 skin bicpsies obtained from 48 patients with epidermal nevus during a 10 year period from January 1981 to December 1990. The results are summarized as follows : 1) Of our 48 patients, 23 were male and 25 were female, and male to female ratio was 1 to 1.1. 2) The average of the patients was 19.8 years at the time of diagnois. 3) Lesions were present at birth in 45.7 percent of patients, and most of the remainder de veloped in childhood. The mean age of onset was 7.7 years. 4) The clinical varieties of the nevi in 48 patients were classified according to caicegories of nevus verrucosus, including systematized epidermal nevus, nevu, unius lateris, ichthyosis hystrix, epidermal nevus syndrome and inflammatory linear veirucous epidermal nevus. The most common type was nevus verrucosus(88.6%). 5) A large variety of histopathologic changes can be seen in epidermal nevi. The most common histopathologic .ype was nonspecific(31.3%), follows by common(12.5%), epidermolytic hyperkertosis(12.5%), and acanthosis nigricans(10.4%). 6) The most commonly affected area was head and neck(48.5%) followed by trunk(28.6%), upper limb(11.4%) and lower limb(2.9%).

PURPOSE: To determine the different of enhancement patterns of hepatic hemangioma according to the lesionsize, using dual-phase spiral CT. MATERIALS AND METHODS: Fify-nine lesions in 45 patients with hepatichemangiomas were subjected to spiral Ct. According to size, the lesions were divided into two groups(< 2.5cm :n=34 ; >_2.5cm : n=25). The enhancement patterns of the lesions were classified as one of four types (homogeneoushyperdense, peripheral hyperdense, central hyperdense, or hypodense) during the early phase, and as one of fivetypes homogeneous hyperdense, peripheral hyperdense, central hyperdense, hypodense or isodense) during the delayedphase. We evaluated differences in enhancement patterns during the early and delayed phase according to lesionsize. RESULTS: During the early phase, the enhancement patterns of lesions large than 2.5cm were peripheralhyperdense(96%) or homogeneous hyperdense (4%);those of less than 2.5cm were peripheral hyperdense (53%),homogeneous hyperdense(26%), hypodense(18%), or central hyperdense(3%). Thus, hemangiomas in these two groupsusually showed a peripheral enhancement pattern during the early phase, but in those which were smaller than2.5cm, atypical enhancement patterns were more common. During the delayed phase, the enhancement patterns oflesions larger than 2.5cm were peripheral hyperdense (60%) or homogenous hyperdense (40%), while the patterns ofthose smaller than 2.5cm were homogeneous hyperdense (67%), peripheral hyperdense (24%), central hyperdense (3%),hypodense (3%), or isodense (3%). Thus, the enhancement patterns of lesions larger than 2.5cm were usuallyperipherally hyperdense during the delayed phase, while those smaller than 2.5cm showed a homogeneous enhancementpattern. CONCLUSION: The enhancement patterns of hepatic hemangiomas differ according to lesion size. A knowledgeof these differences is helpful in the diagnosis of hepatic hemangioma.

Although allergen-specific immunotherapy (AIT) is a standard treatment for allergic diseases, only 5% or less of patients in whom AIT is indicated have been receiving immunotherapy because AIT needs a long-term therapeutic duration of up to 5 years. To overcome this limitation of conventional AIT, Kündig and his colleagues first introduced intralymphatic immunotherapy (ILIT) in patients with allergic rhinitis, publishing their results in 2008. Since then, 10 clinical trials that evaluated therapeutic efficacies and adverse effects of ILIT have been conducted. This article reviews the clinical trials of ILIT and suggests unmet needs in research fields of ILIT.

PURPOSE: Gastric emptying scan (GES) is usually acquired up to 2 hours. Our study investigated whether a fraction of meal-retention in the stomach at 120 minutes (FR120) was predicted from the data measured for 90 minutes by using non-linear curve fitting. We aimed at saving the delayed imaging by utilizing mathematical models. MATERIALS AND METHODS: Ninety-six patients underwent GES immediately after taking a boiled egg with 74 MBq (2 mCi) Tc-99m DTPA. The patients were divided into Group I (T1/2 < or=90 min) and Group II (90 min< T1/2< or=120 min). Group I (n=51) had 21 men and 30 women, and Group II (n=45) 15 men and 30 women. There was no significant difference in age and sex between the two groups. Simple exponential, power exponential, and modified power exponential curves were acquired from the measured fraction of meal-retention at each time (0, 15, 30, 45, 60, 75, and 90 min) by non-linear curve fitting (MATLAB (R) 5.3) and another simple exponential fitting was performed on the fractions at late times (60, 75, and 90 min). A predicted FR120 was calculated from the acquired functional formulas. A correlation coefficient between the measured FR120 and the predicted FR120 was computed (MedCalc (R) 6.0). RESULTS: Correlation coefficients (r) between the measured FR120 and the predicted FR120 of each mathematical functions were as follows: simple exponential function (Group I: 0.8858, Group II: 0.5982, p< 0.0001), power exponential function (Group I: 0.8755, Group II: 0.6008, p< 0.0001), modified power exponential function (Group I: 0.8892, Group II: 0.5882, p< 0.0001), and simple exponential function at the late times (Group I: 0.9085, Group II: 0.6832, p< 0.0001). In all the fitting models, the predicted FR120 were significantly correlated with the measured FR120 in Group I but not in Group II. There was no statistically significant difference in correlation among the 4 mathematical models. CONCLUSION: In the cases with T1/2 < or=90 min, the predicted FR120 is significantly correlated with the measured FR120. Therefore, FR120 can be predicted from the data measured for 90 minutes by using non-linear curve fitting, saving the delayed imaging after 90 minutes when T1/2 < or=90 min is ascertained.

PURPOSE: Recently, a key role of tumor necrosis factor (TNF) in the development of inflammatory bowel disease (IBD), especially Crohn's disease (CD), has emerged. In Japan, 3 single base pair polymorphisms in the 5'-flanking region of the TNF-alpha gene at position 1031, 863, and 857, which are related to high transcriptional promoter activity, have been identified in the Japanese CD patients. And the polymorphisms of the TNF-alpha gene at position 308, 238 have been reported in western CD patients. So, in order to find the same polymorphisms in Korean population and CD patients, the author evaluate the patients diagnosed with CD, ulcerative colitis (UC) and healthy controls (HCs). METHODS: Blood samples were obtained from 70 patients with CD, 72 patients with UC and 52 healthy controls. Polymorphisms in the TNF-alpha gene at their respective positions were analyzed by single strand conformational polymorphism (SSCP), and allele frequencies in CD and UC patients were compared with those in healthy controls. RESULTS: Allele frequencies of 1031C, 863A, and 857T in health controls were 18.3%, 8.7%, and 19.2%, respectively. Polymorphic allele frequencies of 1031C, 863A, 857T were 22.9%, 27.1%, and 24.3% in CD patients respectively. The frequencies at all 3 positions were higher in CD patients than in HCs. However, the frequency at 863A was statistically significant (P=0.000). The allele frequencies of 308A and 238A alleles were 0.7% and 3.6% in CD, 0.7% and 2.1% in UC, and 1.9% and 4.8% in HCs, respectively. The allele frequency of 1031C was significantly higher in B3 than in B2 (P=0.033). CONCLUSION: Polymorphisms of 5'-flanking region of the TNF-alpha at positions 1031 (T/C), 863 (C/A) and 857 (C/T) may be associated with susceptibility of CD.
