PURPOSE: To evaluate the incidence and CT findings of the medial depression and bony dehiscence of lamina papyracea as an anatomic variation. MATERIAL AND METHODS: 1472 PNS CTs of the patients with symptoms of chronic sinusitis were retrospectively evaluated. RESULTS: The total incidence of depressed lamina papyracea as an anatomic variation was 3.5%(52/1472) on PNS CT. There was a statistically significant correlation between the increasing age and the incidence of delamina papyracea. Depression of lamina papyracea anterior to the basal lamella were more common those of the posterior depression. Associated findings were herniation of adjacent fatty tissue in all cases and the roedial bowing and hypertrophied configuration of the medial rectus muscle without significant herniation in 19 cases(34%). CONCLUSION: Nontraumatic, asymptomatic depression with bony dehiscence of lamina papyracea as an anatomic variation is not uncommon with the incidence of 3.5%. Recognition of its existence and degree may helpful in avoiding various ocular complication during ethmoid surgery.

Purpose: To present a case of oculomotor nerve atrophy complicated by herpes zoster ophthalmicus (HZO).Case summary: A 68-year-old man with a history of type 2 diabetes and dyslipidemia complained of diplopia and deviation in left eye. On examination, visual acuity was 20/25 in right eye and 20/20 in left eye. Prism and alternate cover tests revealed right exotropia and hypertropia in the primary position. Examination of ductions and versions showed limitation of adduction and depression in the right eye. On detailed history taking, we found that his symptoms started after suffering HZO on right side about 2 years ago. He was prescribed antiviral agents from a dermatology clinic and was told that all symptoms would improve after medication so he didn't undergo an ophthalmologic examination at that time. Magnetic resonance imaging confirmed that diffuse atrophy of oculomotor nerve in cistern along with atrophic changes of medial rectus and inferior rectus muscles in right eye. A diagnosis of strabismus complicated by HZO-induced oculomotor nerve atrophy was done. Conclusions Ophthalmoplegia secondary to HZO may not be self-limiting and have a poor prognosis resulting in cranial nerve atrophy. A detailed imaging investigation of extraocular muscle and cranial nerves along with thorough history taking are required for proper diagnosis and better prognosis.

Background: Due to the importance of the cold chain related to vaccine transportation, it is necessary to establish a blood cold chain operation strategy by checking the status of blood transportation from blood donation to transfusion. Methods: The blood transportation system and blood storage facilities were checked by inspecting the Korean Red Cross (KRC) Blood Centers and its affiliated supplier and Hanmaeum Blood Center. The status of the cold chain was evaluated through an interview with the quality control manager or blood supply team leader. For the hospital, the status was investigated from the perspective of the 30-min rule. A questionnaire survey was conducted for medical technicians and nurses working at the hospital. Results: Data on temperature during transport of blood components were computerized, and all standards were met. A nationwide network that could supply blood from the blood supply center to the hospitals within 2 hours was established. The frequency of temperature monitoring in the blood transport box and constant temperature check in the transport box during long-distance transport were evaluated. Conclusion This study confirmed that blood storage and transportation in Korea complied with the cold chain standards of high-income countries or higher. The evaluation of the cold chain is a constantly evolving process requiring continuous attention. When standards for storage and transportation of blood products are established, strict regulations and examinations will be required.

On July 6, 2009, an outbreak of gastroenteritis occurred among middle school students in Incheon. An investigation to identify the source and describe the extent of the outbreak was conducted. A retrospective cohort study among students, teachers, and food handlers exposed to canteen food in the middle school was performed. Using self-administered questionnaires, information was collected concerning on symptoms, days that canteen food was consumed, and food items consumed. Stool samples were collected from 66 patients and 11 food handlers. The catering kitchen was inspected and food samples were taken. Of the 791 people who ate canteen food, 92 cases became ill, representing an attack rate of 11.6%. Thirty-one (40.3%) of the 77 stool specimens were positive for Campylobacter jejuni. Interviews with kitchen staff indicated the likelihood that undercooked chicken was provided. This is the first recognized major C. jejuni outbreak associated with contaminated chicken documented in Korea.

BACKGROUND: Although the National Committee for Clinical Laboratory Standards (NCCLS) defined a standard reference broth microdilution method for testing the susceptibility of Candida species to antifungal drugs, many clinical laboratories require easier but reliable alternatives for routine antifungal susceptibility testing. We evaluated ATB FUNGUS 2 (bioMerieux, France.; ATB) compared to the method recommended by the NCCLS (NCCLS). METHODS: A total of 28 strains of Candida species consecutively isolated from blood and CSF cultures at Asan Medical Center from April to June 2004 were tested. In addition, 12 strains comprising C. krusei (3), C. glabrata (7) and C. guilliermondii (2) from the collection of Chonnam National University Hospital were included in the study. These strains were tested for minimum inhibitory concentrations (MICs) against flucytosine (FC), fluconazole (FZ), itraconazole (IZ) and amphotericin B (AB) by both of ATB and NCCLS. In NCCLS, MICs were read using a spectrophotometer after 24 and 48 hour-incubation. RESULTS: The concordance rates of MICs between ATB and NCCLS after 24 hour-incubation were 100%, 75%, 89% and 96% within two-fold dilution and 100%, 97%, 97%, 100% within four-fold dilution for FC, FZ, IZ and AB, respectively. For C. krusei, all three FC and FZ-resistant strains were either intermediate or SDD and one IZ-resistant strain was SDD in ATB, respectively. One C. tropicalis strain resulted in AB MICs of 0.5 microgram/mL in NCCLS, but 2 microgram/mL in ATB. CONCLUSIONS: ATB showed good concordance rates with NCCLS after 24 hour-incubation. ATB appears to be a useful alternatives to NCCLS for routine antifungal susceptibility tests. However, ATB needs further evaluation with more clinical strains, especially those resistant to antifungal agents.

Takayasu's arteritis(TA) is a chronic idiopathic vasculitis mainly involving the aorta and its main branches, such as brachiocephalic, carotid, subclavian, vertebral and renal arteries, as well as coronary and pulmonary arteries. The clinical features usually reflect limb or organ ischemia resulting from gradual stenosis of involved arteries. We experienced a case of idiopathic Takayasu's arteritis with negative tuberculin test involving multiple main branch arteries at active stage without pulse. We treated this patient with combined therapy of steroid and azathioprine, with remission of disease activity.
