Most of orthodontic cases are treated with extraction of certain teeth, which influence the pre-eruptive movement of the lower third molar. The purpose of this study was to evaluate the positional change of lower third molar following orthodontic treatment. Pre- and post-treatment pantomograms of 163 orthodontic patients (77 nonextraction group, 78 first premolar- extraction group. 8 second molar- extraction group) were analyzed in terms of the mesiodistal and buccolingual angles of lower third molar. The results were as follows. 1. The change of the mesiodistal angle of lower third molar by orthodontic treatment was significant in second molar-extraction group. 2. The mesiodistal angle of lower third molar in pre-treatment was significantly correlated to the mesiodistal angle in post-treatment and/or the change of the mesiodistal angle by treatment. 3. The change of the buccolingual angle of lower third molar by orthodontic treatment was significant in non-extraction group or first premolar-extrction group. 4. The change of the buccolingual angle of lower third molar by treatment was significantly correlated to the mesiodistal angle in post-treatment, the change of the mesiodistal angle by treatment, the buccolingual angle in pre-treatment or the buccolingual angle in post-treatment.

PURPOSE: The object of the present study were to clarify the effect of dialysis treatment and residual renal function on olfactory function of patients with chronic renal failure and to assess the correlations between the Cross Cultural Smell Identification Test (CC-SIT) scores and various clinical variables. METHODS: Ninety subjects were studied and divided four groups; age- and sex-matched healthy controls (Control, n=20), patients with varying degree of renal insufficiency but not on dialysis (Pre- dialysis, n=20), patients on CAPD (PD, n=22), and patients on hemodialysis (HD, n=28). We performed olfactory function test using the CC-SIT kit and compared the CC-SIT scores of each of the groups. RESULTS: The CC-SIT scores of each of the groups were; Control : 8.6+/-1.5, Pre-dialysis : 7.2+/-2.0, PD : 8.1+/-1.2, HD : 8.5+/-1.4. In Pre-dialysis group, the CC-SIT scores were significantly lower than Control group (p=0.01). But, no significant difference was observed in the CC-SIT scores between HD and PD group and control group (p>0.05). Creatinine clearance was positively correlated with the CC-SIT scores in control and Pre-dialysis group (r=0.58, p= 0.0001). Total Kt/V was positively correlated with the CC-SIT scores only in HD group (r=0.39, p= 0.03). But, no correlation was found between Kt/ Vurea, URR or residual renal function and the CC- SIT scores in HD and PD group (p>0.05). Age was negatively correlated with the CC-SIT scores only in Control group (r=-0.76, p=0.0001). CONCLUSION: Our results indicate that smell disturbance in patients with chronic renal faliure can be recovered by adequate dialysis treatment.

Foreign bodies in the upper esophagus should be removed as soon as possible to avoid serious complications. These foreign bodies can penetrate the bowel wall and cause severe complications. The peristalsis of the esophagus is not strong enough to prevent it from retaining swallowed objects. Hence, perforation from a foreign body is more likely to occur in the esophagus than in the rest of the gastrointestinal tract. A razor blade is a rare foreign body of the esophagus. Its sharpness and large size make it difficult to remove. A razor blade was very firmly impacted in the esophageal wall in our case, and the razor blade had not moved from the upper esophagus. A standard overtube has limitations to remove a razor blade inside the overtube's lumen. We report here on a case of using a wedge resected overtube made it possible to successfully extract a razor blade and no serious complications occurred after extraction of the razor blade.

Ischemic colitis is generally considered a disease of the elderly. The causes of ischemic colitis include low-flow states due to cardiac dysfunction or hypovolemia and certain medications including estrogen. Here we report a case of ischemic colitis in a 26-year-old woman. She had no specific medical history except taking oral-contraceptives for a long time. The mechanism of estrogen-induced ischemic colitis is not clearly understood. But we recommend that oral-contraceptives should be considered as a cause of ischemic colitis in young women.

Doxylamine succinate is an over-the-counter drug widely used for treating insomnia. We experienced a case of severe rhabdomyolysis complicating acute renal failure after doxylamine overdose in a 24-year- old male. The maximum values of creatine kinase and creatinine level during hospitalization were 264,141 IU/L and 8.4 mg/dL, respectively. Oliguria and severe dyspnea occurred on the sixth hospital day and were treated with hemodialysis. Then, he recovered without any sequelae. To the best of our knowledge, the maximum creatine kinase level of 264,141 IU/L in the present case is the highest value among the case reports on doxylamine-induced rhabdomyolysis and this is the first case report in Korea of doxylamine-induced severe rhabdomyolysis accompanying oliguric acute renal failure and requiring treatment with hemodialysis.

PURPOSE: This study analyzed the tumor response, overall survival, progression free survival and related prognostic factors in patients with muscle invasive bladder cancer subjected to bladder preserving treatment. MATERIALS AND METHODS: Between August 1995 and June 2004, 37 patients with muscle invasive (transitional cell carcinoma, clinically stage T2-4) bladder cancer were enrolled for the treatment protocol of bladder preservation. There were 33 males and 4 females, and the median age was 67 years (range 38~86 years). Transurethral resection of the bladder (TURB) was performed in 17 patients who underwent complete resection. The median radiation dose administered was 64.8 Gy (range 55.8~67 Gy). The survival rate was calculated by the Kaplan-Meier method. RESULTS: An evaluation of the response rate was determined by abdomen-pelvic CT and cystoscopy at three months after radiotherapy. A complete response was seen in 17 patients (46%). The survival rate at three years was 54.7%, with 54 months of median survival (range 3~91 months). During the study, 17 patients died and 13 patients had died from bladder cancer. The progression free survival rate at three years was 37.2%. There were 24 patients (64.9%) who had disease recurrence: 16 patients (43.2%) had local recurrence, 6 patients (16.2%) had a distant recurrence, and 2 patients (5.4%) had both a local and distant recurrence. The survival rate (p=0.0009) and progression free survival rates (p=0.001) were statistically significant when compared to the response rate after radiotherapy. CONCLUSION: The availability of complete TURB and appropriate chemoradiotherapy were important predictors for bladder preservation and survival.
