Background: Univent(R) tube was designed to overcome the disadvantages of double lumen endotracheal tube for one lung anesthesia. But overinflation of the blocker cuff of an endobronchial tube can cause pressure damage to the bronchus. The purpose of this study was to evaluate whether the blocker cuff pressure and the duration of ballooning using the Univent(R) tube is correlated with the degree of bronchial mucosal damage (BMD). Methods: A total of 13 men and 7 women intubated with the Univent(R) tube were enrolled for the study. The BMD were evaluated by direct visualization using fiberoptic bronchoscopy prior to intubation and following extubation and the degree of the BMD were scored from 0 to 4 as follows; 0: normal, 1: erythema, 2: swelling, 3: hemorrhage, 4: mucosal wall tearing. Results: No change in bronchial mucosa (score 0) were observed in 11 patients (55%), erythema (score 1) in 5 patients (25%), swelling (score 2) in 3 patients (15%), hemorrhage (score 3) in 1 patient (5%) and mucosal wall tearing (score 4) is none in 20 patients. The bronchial blocker cuff pressure required to "just sealing" the bronchus was 178.1+/-37.4 mmHg with corresponding cuff volume of 6.7+/-1.0 cc. The duration of ballooning was 115.5+/-26.4 min. The correlation coefficient between the blocker cuff pressure and duration of ballooning to the degree of bronchial mucosal damage were 0.125 and 0.137, respectively, which was not statistically significant. Conclusions: The bronchial blocker of Univent(R) tube doesn't cause any severe BMD and the degree of BMD are correlated with neither the bronchial blocker cuff pressure nor duration of ballooning of Univent(R) tube.

This study was designed to estimate the prevalence of hepatitis C virus(HCV) infection in drug abusers. The subjects were 141 inpatients who had been admitted to a general hospital with the symptoms and signs of methamphetamine intoxication. Seroprevalence of antibody to the hepatitis C virus(anti-HCV) was 60.3%,(85/141) and it was higher in the group with increased frequency and duration of drug abuse, but such a relationship was not found in the seroprevalence of hepatitis B surface antigen(HBsAg). These findings suggested the possibility of high prevalence of HCV infection in methamphetamine abusers, and the importance of repetitive percutaneous injection in the transmission of HCV infection.

Juvenile xanthogranuloma is characterized by one, or oftener many, yellow, re3dish yellow, or, brown 4-to-20 mm papules or nodules on the face, scalp, trunk, and mostly, extensor surfaces. It may involve internal organ besides the skin such as eye, gastrointestinal and genitourinary tracts. anthogranuloma in adult is usually solitary and dose not involve organs other than skin, and generally dose ncit resolve without treatment. Histopathologically, characteristic Touton giant cells usually appear numerously. We report a case of juvenile xanthogranulorna which occured on scalp of 49 year-old male showing typical clinical and histopathological findings.

In systemic rheumatic disease, marker antibodies such as anti-Sm, anti Scl-70 and anti Jo-1 are helpful in the diagnosis of disease, but in rheumatoid arthritis, the diagnosis is difficult due to the low sensitivity and specificity of the rheumatoid factor(RF). So, a new maker antibody with high sensitivity and specificity was needed. Recently, the antiperi- nuclear factor(APF) has gained particular attention. The results of the APF and RF test in 165 patients with rheumatoid arthritis, 77 patients with osteoarthritis, and 109 normal healthy persons, which were taken between January, 1994 through December 1994 were as follows; 1. The sensitivity, specificity, and predictive value of positivity of the RF test in patients with rheumatoid arthritis were 58.2%, 93.5%, and 95.0%, and that of the APF test were 72.1%, 94.6% and 92.2%, respectively. 2. The sensitivity, specificity and predictive value of positivity when combining the APF with the RF were 83.0%, 85.7%, and 92.6%, respectively. 3. The disease status of the patients correlated with intensity of the APF test, that is, the more severe the disease status, the higher intensity. In conclusion, the APF was useful in the diagnosis of rheumatoid arthritis, and may be used as an indicator of disease status. When combining test the APF with RF, the incidence of sero-negative rheumatoid arthritis decreased.

PURPOSE: To compare the lamina cribrosa thickness in fellow eyes of patients with unilateral retinal vein occlusion (RVO) with the normal control eyes and the type of RVO. METHODS: This study included 40 patients with unilateral RVO and 45 normal control subjects. We compared the lamina cribrosa thickness between the RVO eyes and the fellow eyes, the fellow eyes and the normal control eyes and the type of RVO eyes. We measured central lamina thickness using enhanced depth imaging spectral-domain optical coherence tomography. RESULTS: In patients with unilateral RVO, central lamina cribrosa thickness was not significantly different between the RVO eyes (211.33 microm) and the fellow eyes (204.13 microm; p = 0.202). However, central lamina cribrosa thickness in the fellow eyes was significantly reduced compared with the normal control eyes (217.76 microm; p = 0.046). Central lamina cribrosa thickness in the fellow eyes according to the type of RVO was not statistically significantly different (p = 0.672). CONCLUSIONS: This study showed that the central lamina cribrosa thickness in the fellow eyes of patients with unilateral RVO was thinner than in normal patients. Therefore, the lamina cribrosa thickness may be associated with RVO as well as glaucoma.

PURPOSE: In spite of appropriate management, ophthalmic artery occlusion has a poor prognosis and eventually progresses to the blindness or phthisis bulbi. We report one unusual cause of ophthalmic artery occlusion for the preventive purpose. METHODS: A 44 year-old woman visited emergency room with an acute visual loss in the left eye and right hemiplegia. She had undergone illegal augmentation rhinoplasty using liquid silicone one day prior to the presentation. RESULTS: Angiogram showed that injected liquid silicone entered the systemic circulation via nasal vein and induced the left cerebral infarction and left ophthalmic artery occlusion. On the 30th hospital day, right carotid cavernous fistula was developed with right ocular pain.

PURPOSE: To investigate the changes in choroidal thickness in diabetic retinopathy patients after panretinal photocoagulation (PRP). METHODS: This retrospective study included 42 eyes of treatment-naive, severe non-proliferative diabetic retinopathy or proliferative diabetic retinopathy patients undergoing 3-session PRP. At baseline and 1 and 2 months after completion of the PRP treatments, subfoveal choroidal thickness (SFCT) was measured using enhanced depth imaging optical coherence tomography. RESULTS: The mean SFCT at baseline was 261.52 +/- 77.98 microm, changing to 249.14 +/- 72.23 microm and 242.95 +/- 70.28 microm at 1 and 2 months, respectively (p < 0.05). The mean central macular thickness (CMT) was increased (>10%) in 9 eyes (21.43%) at 1 month and 8 eyes (19.05%) at 2 months after PRP. The mean SFCT showed no significant difference between increased mean CMT (238.22 +/- 57.59 microm and 240.00 +/- 67.71 microm at 1 and 2 months, respectively) and stable mean CMT groups (252.12 +/- 76.24 microm and 243.65 +/- 71.84 microm at 1 and 2 months, respectively; p > 0.05). CONCLUSIONS: Choroidal thickness decreased after PRP. There was no significant relationship between change in SFCT and CMT after PRP.
