Endotracheal intubation has been widely used for general anesthesia and patency of airway. But intubation granuloma may be developed after intubation. From Feb. 1986 to Jun. 1993, the authors encountered 20 cases of intubation granuloma in Korea University Hospital and following results were obtained. 1) The incidence of intubation granuloma was 0.017%. 2) The age range was from 24 to 49 years. 3) The ratio of male to female was 1 to 19. 4) All cases located at posterior one third of vocal cord, 6 cases were bilateral, 14 were unilateral, of them 10 were in the right sides. 5) Eleven cases were occurred after caesarian section, and the ineidence of which was 0.134% . 6) Hoarseness was the main symptom in 18 cases. 7) The duration from intubation to development of symptom was 15 days to 4 months.

BACKGROUND: Transfer of foreign genes to the renal glomerular cells is an important step for the gene therapy of renal diseases in which the primary pathology is confined to the glomeruli. We developed a non-surgical method of gene transfer to rabbit renal glomeruli using percutaneous arterial catheterization without any laparatomy procedure. METHODS: The recombinant adenovirus type 5, containing a nuclear-targeted beta-galactosidase gene and driven by a cytomegalovirus promoter, was slowly infused into the unilateral renal artery via percutaneous arterial catheterization. The animals were sacrificed 3 days after virus infusion and lacZ staining was done on the fresh harvested tissue. RESULTS: Only the animals those received 6x10(12) particles/rabbit for 120 minutes show lacZ expression in 90.6+/-5% (n=3) of glomeruli. Mostly, it was the endothelial cells and mesangial cells those were positive for the stain. CONCLUSION: This non-surgical method for gene transduction of the renal glomeruli can be applied to human trials of glomerulus-directed gene therapy.

OBJECTIVE: The aim of the present study was to investigate differences in discontinuation time among antidepressants and total antidepressant discontinuation rate of patients with depression over a 6 month period in a naturalistic treatment setting. METHODS: We reviewed the medical records of 900 patients with major depressive disorder who were initially prescribed only one kind of antidepressant. The prescribed antidepressants and the reasons for discontinuation were surveyed at baseline and every 4 weeks during the 24 week study. We investigated the discontinuation rate and the mean time to discontinuation among six antidepressants groups. RESULTS: Mean and median overall discontinuation times were 13.8 and 12 weeks, respectively. Sertraline and escitalopram had longer discontinuation times than that of fluoxetine, and patients who used sertraline discontinued use significantly later than those taking mirtazapine. No differences in discontinuation rate were observed after 24 weeks among these antidepressants. About 73% of patients discontinued antidepressant treatment after 24 weeks. CONCLUSION: Sertraline and escitalopram tended to have longer mean times to discontinuation, although no difference in discontinuation rate was detected between antidepressants after 24 weeks. About three-quarters of patients discontinued antidepressant maintenance therapy after 24 weeks.

PURPOSE: Integration of the functional information of myocardial perfusion SPECT (MPS) and the morphoanatomical information of coronary CT angiography (CTA) may provide useful additional diagnostic information of the spatial relationship between perfusion defects and coronary stenosis. We studied to know the added value of three dimensional cardiac SPECT/CTA fusion imaging (fusion image) by comparing between fusion image and MPS. MATERIALS AND METHODS: Forty-eight patients (M:F=26:22, Age: 63.3+/-10.4 years) with a reversible perfusion defect on MPS (adenosine stress/rest SPECT with Tc-99m sestamibi or tetrofosmin) and CTA were included. Fusion images were molded and compared with the findings from the MPS. Invasive coronary angiography served as a reference standard for fusion image and MPS. RESULTS: Total 144 coronary arteries in 48 patients were analyzed; Fusion image yielded the sensitivity, specificity, negative and positive predictive value for the detection of hemodynamically significant stenosis per coronary artery 82.5%, 79.3%, 76.7% and 84.6%, respectively. Respective values for the MPS were 68.8%, 70.7%, 62.1% and 76.4%. And fusion image also could detect more multi-vessel disease. CONCLUSION: Fused three dimensional volume-rendered SPECT/CTA imaging provides intuitive convincing information about hemodynamic relevant lesion and could improved diagnostic accuracy.

BACKGROUND: Performing antibody screening and identification tests before blood transfusion are important since unexpected red cell antibodies can cause acute or delayed hemolytic transfusion reactions. We investigated the frequency and distribution of unexpected red cell antibodies that were detected in cancer patients at National Cancer Center (NCC) and we compared our results with the previously published data. METHODS: From January 2001 to June 2009, 56,660 sera of the cases from NCC were screened and 197 sera were identified with using the Ortho BioVue System (Ortho-Clinical Diagnostics, Raritan, USA) and the conventional tube method. In case of the presence of autoantibody, the ZZAP method was performed to distinguish alloantibody from autoantibody. RESULTS: 759 cases (1.34%) showed positive results out of all 56,660 cases that underwent unexpected antibodies screening. Among them, unexpected antibodies were identified in 197 cases. The most frequently detected antibody was anti-Le(a) in 62 cases (31.47%), followed by anti-E in 32 cases (16.24%) and anti-Le(b) in 18 cases (9.14%). Unidentified antibodies were detected in 43 cases (21.83%). In the cases with a previous history of transfusion at the NCC and the screening results were altered from negative to positive, anti-E was the most frequently detected antibody (8/30 cases, 26.67%), and this included the mixed antibodies. CONCLUSION: Compared with the previous reports, this study showed that the frequency and distribution of the unexpected red cell antibodies of cancer patients were not different from those of general patients. Moreover, there was no apparent difference of frequency of the unexpected red cell antibodies among the diagnosed cancers. Our research may provide data for the frequency and characteristics of red cell antibodies because we targeted only cancer patients.

Chronic cough is defined as a cough that lasts for more than three weeks. In most patients, chronic cough is caused by four conditions: postnasal drip, asthma, chronic bronchitis, gastroesophageal reflux. Psychogenic chronic cough is not a frequent disorder. Furthermore, chronic vocal tic disorder is a very rare cause of chronic dry cough. A 22- year-old male suffered from chronic dry cough for last two years. His character showed obsessive- compulsive disorder. He has been shrugging both shoulders inadvertently since his childhood. Consequently, he was diagnosed as having chronic motor tic disorder. But after contracting respiratory tract infection, his motor tic disappeared and chronic dry cough was developed concomitantly. He had no history of smoking, chronic rhinitis, sinusitis, asthma, and gastroesophageal reflux. Physical examinations were normal. Chest X-ray, paranasal sinus view, metacholine bronchial provocation test, and esophago-gastroscopy were normal. Chronic cough was never relieved despite empirical treatment. Psychiatric consultation suggested chronic vocal tic disorder. The frequency of cough was diminished two days after administeration of valium and haloperidol and thereafter his complaint disappeared in one month. Here we report a very rare case of chronic motor tic disorder which was transformed into chronic vocal tic disorder presenting as a chronic cough. As far as we know, this is the first case of its kind in Korea.
