Conventional hemorrhoidectomy is still the main stairway to the treatment of the third or the fourth degree hemorrhoids. Among the various methods of hemorrhoidectomy, open hemonhoidectomy is claimed to decrease postoperative pain and wound infection, but to have disadvantage of long period of wound healing. Semi-closed hemorrhoidectomy has the advantage of rapid wound healing without increased risk of wound infection, but more painful postoperative course than open hemorrhoidectomy is suggested. To assess this conventional concept, two hundreds of patients were randomly allocated to either an open hemorrhoidectomy(Group 4, Operated by modified Goligher method, n=100) or a semi-closed hemorrhoidectomy(Group B, Operated by modified Nesselrod method, n=100), and postoperative results were analyzed. In group 4, the average time for disappearance of wound edema was 4.9days, average time for disappearance of wound pain was 9.0days, average time for painless defecation was 14.1 days, average time for complete wound healing was 28.4days. The main complications were overgranulation, skin tag, anal discharge and pruritus. The overgranulation requires curettage, the skin tags were resected under local anesthesia. Anal discharge and pruritus were spontaneously disappeared after the healing of the wound. In group B, the average time for disappearance of wound edema was 6.1 days, average time for disappearance of wound pain was 6.3days, average time for painless defecation was 9.2days, average time for complete wound healing was 20.7days. The main complications were skin tags, more prevalent than group 4, requiring resection under local anesthesia. No infectious complications were noted in both groups. Consequently, the old concept that open hemorrhoidectomy has advantage of less painful postoperative course than semiclosed hemorrhoidectomy cannot be accepted. Semi-closed hemorrhoidectomy offers more rapid loss of pain and more rapid healing of the wound than open hemorrhoidectomy, without increased risk of infectious complications. In conclusion, semi-closed hemorrhoidectomy is superior method to open hemorrhoidectomy in third or fourth degree hemorrhoids.

PURPOSE: To evaluate the efficacy of the arterial phase of dynamic spiral CT in the detection of pancreatic adenocarcinoma compared with the late phase. MATERIALS AND METHODS: Two phase spiral CT images of seventeen patients with pathologically proven pancreatic ductal adenocarcinomas were compared retrospectively. CT scans were performed with 5mm collimation at 1:1 pitch table speed. Images of arterial and late phases were obtained at 35 seconds and 180 seconds after initiation of administration of 100mL of contrast material(3mL/sec), respectively. Images of the arterial phase were compared with those of the late phase. RESULTS: Images of the arterial phase showed sufficient contrast between the tumor and adjacent pancreatic parenchyma in 12 cases, insufficient in four cases, and no significant contrast in one case. Images of the late phase showed sufficient contrast in five cases, insufficient in five cases, and no significant contrast in seven cases. Images of the arterial phase was superior to that of the late phase in 12 patients(70.6%). In six of the 12 patients, only the images of the arterial phase showed contrast between the tumor and the adjacent parenchyma. The images of late phase showed only one case of three metastasis detected on the images of the arterial phase. CONCLUSION: The arterial phase of spiral CT is superior to the late phase that is comparable with conventional CT in the detection of pancreatic adenocarcinoma.

Two cases of Castleman's disease (Giant lymph node hyperplasia) are reported. The first case was a multicentric cervical giant lymph node hyperplasia. Excisional biopsy confirmed the diagnosis of Castleman's disease of the plasma-cell type. Despite repeated dissection of the cervical lymph nodes, complete removal of the lymph nodes was impossible, and the type was changed into mixed type, and regrowth of the tumor was noted. Prednisolone was of no benefit. The patient is now living with cervical masses in situ without general symptoms, 4 years after the initial diagnopsis. The second case was a solitary retroperitoneal giant lymph node hyperplasia, incidentally found. Complete excision was performed and biopsy confirmed the diagnosis of Castleman's disease of hyaline-vascular type. No recurrence was found at 2 years after the excision.

We have used mivacurium in two myasthenic patients, a generalized myasthenia gravis (MG) patient presenting for thymectomy and a Lambert-Eaton myasthenic (LEM) patient for mediastinoscopic lymph node biopsy. Both of them received nitrous oxide/oxygen (1:1)-narcotic-enflurane anesthesia with mivacurium as a muscle relaxant and the neuromuscular blocking effect of mivacurium was monitored continuously through the operation as well as before the induction of anesthesia. The dose of mivacurium for MG patient was 5.5 mg and LEM patient was 12 mg, because MG patient showed more severe clinical symptoms. The response to train-of-four (TOF) ulnar nerve stimulation was recorded using accelography. The onset times to maximal block in MG and LEM patients were 30 and 120 sec, respectively after injection and the recovery times to 25% from maximal block were 117 and 76 min, respectively. Mivacrium would be safe and appropriate for use in myasthenic patients, with relatively small dose under the neuromuscular monitoring.

PURPOSE: This is a report on the outcomes associated with a consecutive series of 1,000 cementless hip arthroplasties utilizing the Bencox® hip stem–the first Korean-developed hip prosthesis. MATERIALS AND METHODS: A consecutive series of 1,000 hip arthroplasties using the Bencox® hip stem were analyzed, starting from its initial release (September 2006) until June 2014. Patients in this consecutive series underwent surgery for fractures (n=552), arthritis (n=155), avascular necrosis (n=209), and revisions (n=84). Of these 1,000 cases, patients with a minimum follow-up of at least 1 year (n=616) were retrospectively analyzed for radiographic and clinical outcomes (i.e., Harris hip score). The stability of the prosthesis was evaluated by examining subsidence. RESULTS: During the follow-up period (mean follow-up period of 54.8 months), there were 2 cases requiring revision of the femoral stem–both were caused by periprosthetic fractures and neither involved stem loosening. The mean Harris hip score during follow-up was 95.5. Bone ongrowth occurred in 95% of patients; no cases of subsidence or aseptic loosening of the stem were detected, and no cases of postoperative complications such as ceramic breakage were observed. CONCLUSION: Clinical and radiographic evaluations of hip arthroplasty using the Bencox® hip stem revealed excellent outcomes with an average of 54.8 month follow-up in a consecutive series of 1,000 cases.

OBJECTIVE: Cross-sectional survey was performed to evaluate prevalence of allergic rhinitis and its causative allergens in people in rural area of Cheju Isl~and. Subject and METHOD: A total of 1,236 people with 1,055 children and 181 adults in rural area of Cheju Island were enrolled in this study. In children, 544 were males and 511 were females, and their mean age was 12.3(ranging from 7 to 16) years. In adults, 78 were males and 103 were females, and their mean age was 50.1 (ratging from 18 to 87) years. Evaluations included a questionnaire survey, and skin prick test with extracts of Japanese cedar (Cryptomera japonica, J cedar) pollen and citrus red mite (Panonychus citri, CRM) as well as eleven common inhalant allergens. RESULTS: Prevalence of chronic nasal symptoms was 40.6% (429/1,055) in children, and 45.8 % (83/181) in adults. Prevalence of allergic rhinitis based on positive nasal symptoms on the questionnaire and positive skin response to one or more of the 13 inhalant allergens were 15.4 % (159/1.035) in children, and 19.3% (35/181) in adults. Of 1,035 children, skin-test response was positive in 37.6%, and common sensitizing allergens in order of decreasing frequency were Dermatophagoides pteronpssinus (DP) (26.6%), D. farinae (DF)(22.6%), CRM(14.2%), cockroach(11.3%) and J cedar(9.7%). Of 181 adults, skin-test response was positive in 25.9%, and t,he most common sensitizing allergen was CRM(16.5%), followed by cockroach(11.0%), DP(9. 9%), DF(9.4%), and J cedar(6.6%). Of 159 children with allergic rhinitis, the common sensitizing allergens in order of deereasing frequency were DP(79.2%), DF(67.3%), CRM(35.8%), J cedar(32.7%), and cockroach(27.0%). Of 35 adults with allergic rhinitis, the most common sensitizing allergen was CRM(68.6%), followed by DP(40%), DF(34.3%), cockroach(34.3%), and J cedar(28.9%). CONCLUSION: Allergic rhinitis is a very common disease with a prevalence of 15.4% in children and 19.3% in adults in rural area of Cheju island, and common sensitizing allergens include house dust mite, citrus red mite, cockroach, and Japanese cedar pollen.

BACKGROUND: Prevalence of bee venom allergy in Korea is unknown, OBJECTIVE: We performed a cross-sectional study to evaluate the prevalence of bee venom allergy and importance of risk factors, such as age, sex, and atopy, in the development of the allergic reaction in children and adults living in rural area of Cheju Island. Swbject and METHOD: The prevalence was investigated in subjects with 1,054 children and 370 adults (701 male, 723 female), aged 7-87 years, living in rural area of Cheju Island. A history particularly focused on the systemic reactions after the bee stings was taken in all subjects. Skin prick test,s to common inhalant allergens, including house dust mites, fungi, tree, grass, mugwort and ragweed pollen, cockroach, animal epithelium, Japanese cedar pollen, and citrus red mite were performed. RESULT: The prevalence of bee venom allergy was 5.8% (mild systemic reactions 5.0%, severe systemic reactions 0.8% ). The prevalence was higher in adults than in children (10.2% vs. 5.0%, g = 12.0, p<0.01). Among the children, the prevalerlce wB.S Signifcantly higher ill male than in female (8.6% vs. 1.3%, x=28.7, p<0.01), but no significant diffecence was noted between male and female in adults (10.0% vs. 10.3%, p>0.05). The prevalence of bee venom allergy was not significantly different between subjects with positive skin reaction and those with negative skin reaction to inhalant allergens (6.4% vs. 5.4% ), Conclasion'. The prevlence of bee venom allergy in inhabitants of rural area of Cheju Island is 5.8% (mild systemic,' 5.0%, severe systemic reaction. 0.8%), and bee venom allergy was more common in adults than in children, and in male children than in female children.
