Grave's disease is an autoimmune disorder and affects thyroid gland and orbit. Ocular manifestations of this disease, referred to as Grave's ophthalmopathy are caused by deposition of antithyroglobulin immune complexes into extraocular muscles and orbital fats. Consequent increase in volume of orbital contents results in exopthalmos. Severe exopthalmos results in several significant visual consequences as follows: exposure keratitis, diplopia and optic neuropathy. Orbital decompression for Grave's ophthalmopathy has traditionally been performed through either an external or a transantral approach. The advent of intranasal endoscopes allowed for the development of a transnasal approach for medial and inferior orbital wall decompression. Recently, the authors experienced a case of Grave's ophthalmopathy complicated with exposure keratitis and performed endoscopic transnasal orbital decompression, so report this case with a review of literature.

BACKGROUND: Experimental data indicate that low-flow reperfusion following prolonged cardiocirculatory arrest may aggravate early cerebral microcirculatory repefusion disorders. We investigated the influence of cerebral repefusion flow change to the ischemic histopathologic damage of brain tissue after incomplete forebrain ischemia in rats. MATERIALS AND METHOD: Anesthetized Sprague-Dawley rats were undergone ligation of both infernal carotid artery by microvascular clamp for 10 minutes. After release of the clamp, reperfusion was started with several different flow levels (0, 10, 20, 30, 50, and 100%) of infernal carotid artery comparing to pre-clamping phase using flowmeter. After 15minutes of reperfusion, rat brains were prepared by perfusion-fixation with 3% formaldehyde. Under light microscopic examination of Hematoxylin-Eosin stained tissue slide, histopathologic damage was examined at cortex, putamen, and hippocampus regions. Categorical hisotopathologic damage scores were derived in each regions by manual counts of ischemic neurons. RESULT: The histopathologic damage scores were 0, 10. 2+/-0.5, 7.6+/-1.5, 5.9+/-1.4, 5.0+/- 2.8, 3.5+/-0.7, and 1.0+/-0.0 in control, 0, 10, 20, 30, 50, and 100% reperfusion groups, respectively(p<0.05). CONCLUSION: Our insults showed significant increment of brain histopathologic damage scores along with decreasing amount of cerebral reperfusion know after incomplete forebrain ischemia. We believe restoration of repefusion flow to pre-ischemic level would be a critical component in attenuation of brain ischemic damage.

Duplex ultrasonography (USG) is an accepted method to assess noninvasively arterial inflow to the penis. Optimal pharmacological agents as well as timing of the scan and stimulation during the scan continue to be debated. Between August 1994 and May 1996, 24 normal males (control group) and 45 impotent patients (impotence group) underwent penile doppler sonography, and their records were reviewed. Scans were performed at 1, 3, 5, 10, 15, 20 and 30 minutes after intracavernous injection of PGE1 (10 pg) in all subjects. Any subject not having a full erection at 15 minutes performed private self-stimulation for at least 5 minutes before the 30 minute scan. If we define normal arterial inflow as a peak systolic velocity (PSV) of 30 cm. per second or greater in the best artery, 46% of control group and 55% of impotence group achieved this velocity until 5 minutes. One (4%) of control group and three (6%) of impotence group achieved maximum velocity at 1 or 3 minutes but continually PSV of 30 cm. per second or greater after 5 minutes, so any subject may not have had an incorrect diagnosis. When we calculated maximum velocity in the best artery in relation to percentage tumescence, maximum velocity were recorded most often at 10% tumescence (46% of control group and 51% of impotence group). If we define normal arterial inflow as PSV of 30 cm. per second or greater in best artery, the cumulative percentage of patients who achieved this velocity at 1, 3, 5, 10, 15, 20 and 30 minutes were 4, 34, 46, 88, 96, 96 and 100% in control group and 6, 28, 55, 90, 92, 94 and 96% in impotence group. In conclusion, we support delaying the initial scan until 5 minutes, performing the additional scans until 30 minutes and self-stimulation when necessary. We believe all efforts should be made to have studies performed in the setting of least anxiety to the patient.

Renal cell carcinoma is an uncommon tumor in children and only 3-5 percent of the renal cell carcinoma occur under age of twenty. Interestingly, some of the patients had a history of trauma occurring shortly before the onset of symptom calling attention to the tumor. In histology of renal cell carcinoma, clear cell type is most common and papillary type is 10-15 percent. The papillary type of renal cell carcinoma is characterized by better prognosis than non-papillary types. We report a case of papillary type of renal cell carcinoma which was detected incidentally after trauma in 13-year-old male patient.

PURPOSE: This study was designed to investigate that men with prostatodynia have petechiae in the bladder and improvement of symptoms after hydrodistension. MATERIALS AND METHODS: A total of 14 men with the diagnosis of prostatodynia underwent cystoscopy and hydrodistension under a general or regional anesthetic. Their charts were retrospectively reviewed. RESULTS: Of the 14 men 5(36%) had moderate to severe petechiae similar in appearance to women with interstitial cystitis after hydrodistension. Men with moderate to severe bladder petechiae had fewer leukocytes in expressed prostatic secretions and smaller bladder capacities than men with more normal appearing bladders after hydrodistension. Symptomatic improvement 2 to 6 weeks after hydrodistension was more common in men with moderate to severe petechiae than in those with fewer petechiae. CONCLUSIONS: We suggest that bladder petechiae after hydrodistension may be a diagnostic finding in men with prostatodynia as well as women with interstitial cystitis. Therefore, the diagnosis of interstitial cystitis should be considered in patients with prostatodynia.

BACKGROUND: Norwegian scabies is a highly infectious disease characterized by crust formation, different from ordinary scabies, and is caused by Sarcoptes scabiei. After the patient in our case was diagnosed with Norwegian scabies, active measures were taken to prevent its transmission within the hospital. Methods: A 66-year-old female patient was admitted to the general ward of a university hospital on January 23rd, 2008 and 6 days later, she was found to have been infected with Norwegian scabies all over the body. For epidemiological investigation, those who had been in contact with the patient were identified and interviewed. The patient was advised to follow the contact precaution, and linen the patient used was cleaned thoroughly. The surrounding environment was decontaminated by applying surface disinfectant. Preventive cream against the Norwegian scabies was distributed to staff members and patients who had been exposed to the patient, and appointed a dermatologist to educate them on how to use of medicine, what the mechanism of the disease is, what cautions must be taken, and how to write an ex post facto report. RESULTS: After the confirmation of the 1st case, no additional cases have been reported in the hospital during the ensuing 2 months. Therefore, prompt prevention and infection control activities against Norwegian scabies can be thought to have been successful. CONCLUSION: Whena patient with an uncertain skin disease is admitted, pertinent measures must be taken from the moment the patient is admitted and contact precaution should be applied both to the patients and the staff members. When a scabies patient is detected in an institution, the medical staff must enforce as much active preventive measures as possible, and by doing so, there will be a better chance to prevent the outbreak of scabies in the hospital.

PURPOSE: To find the effect of visual feedback of head angle with using a mobile posture-aware system on craniocervical angle and neck and shoulder muscles fatigue for preventing or decreasing the forward head posture. METHODS: Twenty-four healthy young adults in Chungbuk to participate in this study. The subjects started to watch a movie clip for 10 minutes with visual feedback in 0°, 30°, and 60° of head angles. During the task, surface electromyography (EMG) was used to collect data from the upper trapezius (UT), sternocleidomasetoid muscle (SCM), cervical erecter spinae (CES) during watching the smartphone. Craniocervical angles were measured using a sagittal-view photograph of the subject in a sitting posture. A one-way repeated analysis of variance with a significant level of 0.05 used for statistical analysis. RESULTS: Craniocervical angle with 0° visual feedback was significantly greater than 30°and 60°. Craniocervical angle with 30° visual feedback was significantly greater than 60°. In addition, MDF of UT muscles in 0° and 30° of visual feedback was significantly greater than 60°. CONCLUSION: We concluded that 0° visual feedback of head angle with using a mobile posture-aware system would be beneficial to prevent or decrease forward head posture during watching a smartphone. We also could recommend using of 30° visual feedback in case of caring UT muscle fatigue primarily.

PURPOSE: To reassess the diagnostic value of plain radiographs, compared with computed tomography, in thediagnosis of acute traumatic spinal fracture. MATERIALS AND METHODS: Forty-six patients (total 64 cases) withacute traumatic spinal fracture were studied using plain radiographs and computed tomography. Fracture site andtype (according to the three-column theory), classification as major or minor injury, stability of fracture, andthe presence of associated soft tissue change were evaluated on plain radiographs and CT. The results of the twoimaging techniques were compared. RESULTS: Excluding eight cases of C1 and C2 fractures, 41 cases involvedfractures of the vertebral body, and 15 involved only the posterior column. Plain radiographs and CT showed,respectively, 27 and 25 cases of simple compression fracture, 13 and 16 of bursting fracture. One case ofcompression fracture was not detected on plain radiographs. The results of classification as major (43/56) orminor (13/56) injury were equivalent on plain and CT films. For the evalvation of unstable fracture, plainradiographs were superior to CT(stable fracture, 46/64; unstable fracture, 18/64), while for the evaluation ofsoft tissue change, CT was better than plain radiographs. CONCLUSION: If correct procedures are meticulouslyadhered to, plain radiographs of acute traumatic spinal injury provide good information for the diagnosis oftraumatic fracture.
