The technique of plssma exchange has been applied to a number of immune disorders in which c4eulating antibodies are present. We observed a patient with bullous pemphigoid and serious side effects of longterm use of steroid therspy. We applied ten times of plasmapheresis to him over six months period. After the plasmapheresis, clinical symptoms have greatly improved and steroid maintenance doses have been decreased. We have not observed any side effect of plasmapheresis such as thrambotopenia or hypogarnrnaglobulinemia during the whole therapeutic period.

Anesthesia for thoracic surgery is most commonly performed with the patient in the lateral decubitus position, with nondependent hemithorax comprising the operation field. When one-lung ventilation is employed, the nondependent lung is nonventilated and collapsed, while the dependent lung is ventilated. Consequently one-lung ventilation creates an obligatory right to left transpulmonary shunt through the nondependent nonventilated lung. Therefore one-lung ventilation results in a much larger alveolar-arterial oxygen tension-difference P(A-a)O2 and lower PaO2 than does two-lung ventilation. The present study was to evaluate oxygenation effect of selective CPAP to nondependent lung in the 17 thoracic surgical patients. Arterial blood gases were analysed, systolic blood pressures and heart rates were measured at following stages. Stage I; lateral decubitus position before chest opening Stage II; 15 min after chest opening and one lung ventilation stage III; 15 min after application of selective CPAP 5 cmHO to the nondependent lung stage IV; 40 min after application of selective CPAP 5 cmHO to the nondependent lung The results were as follows: 1) In stage II, the value of PaO2 was significantly lower as compared to that in stage I(224.9+/-78.0 vs 418.2+/-63.1 mmHg, P<0.01). 2) In stage III and IV, the values of PaC4 were significantly higher.as compared to that in stage II(333.8+/-97.1, 364.5+/-88.6 vs 224,9+/-78.0 mmHg, P<0.01). 3) In stage III, the value of PaCO2 was significantly lower as compared to that in stage II(37.1+/-2.9 vs 38.2+/-2.7 mmHg, P<0.05). 4) In stage IV, the value of pH was significantly lower as compared to that in stage III(7.37+/-0.05 vs 7.38+/-0.05 P<0.05). 5) Systolic blood pressures and heart rates remained unchanged at all times. We concluded that application of 5 cmHO CPAP to the nondependent lung during one-lung ventilation is one of most efficacious maneuvers to increase PaO2, accompanying less surgical interference.

Angioleiomyoma is a type of benign smooth muscle tumor. It is common in uterus and the gastrointestinal tract but rare in head and neck. This neoplasm is extremely rare in the larynx as only 10 cases have been reported in the literature in the world so far. Main symptoms are hoarseness and dyspnea. The treatment of choice is complete removal with care taken to avoid profuse bleeding. The authors report one case of angioleiomyoma of the larynx that was excised surgically with CO2 laser under suspension microlaryngoscopy.

PURPOSE: In order to help identifying the subgroups of primary megaureter who neck operation, we retrospectively reviewed the clinical records of the patients who had primary megaureters without vesicoureteral reflux. MATERIALS AND METHODS: We analyzed the initial differential renal function, UTI rate and the incidence of breakthrough infection of each group. Every patient had abdominal renal ultrasonograms and diuretic renograms during his/her follow-up period and the calyceal changes and differential renal functions were assessed. RESULTS: Those who underwent operation in their neonatal period did not have considerable postoperative problems. Those with primary obstructive megaureters who underwent operation had severe calyceal dilatation at the initial evaluation. However, there were severe calyceal dilatation in the nonobstructive-nonrefluxing group, too. Those who had poor differential renal function at the initial evaluation had a greater chance to have surgical correction. Those who were classified as primary obstructive megaureter and underwent operation had a higher rate of urinary tract infection than the counterpart who had consevative care. CONCLUSIONS: In order to differentiate those who need operation, we think that the differential renal function, the calyceal morphology, The diuretic renogram curve and urinary tract infection all act as combined factors altogether and not a single factor acts as a contributing factor. That is, if the diuretic renogram cutie is obstructive and there is urinary tract infection in the initial evaluation or if there is severe calyceal dilatation and decline of the differential renal function, we think that surgical correction should be under consideration. In contrast, if the diuretic renogram cutie is not obstructive and there are other factors combined, we think that conservative treatment should be the choice only if there is no breakthrough infection.

Background: This study aimed to investigate trends in the prevalence of current smokers and motivation to quit among Korean male cancer survivors. Methods: Out of 20,012 men who participated in the Korea National Health and Nutrition Examination Survey V (2010–2012), VI (2013–2015), and VII (2016–2017), 742 cancer survivors were included. A cancer survivor was defined as a person who concurred to the item, “The cancer has been diagnosed by a doctor” in the health questionnaire. Smoking status was classified as current, former, and never smokers. Regarding motivation to quit smoking, we defined those who had a willingness to quit within 6 months as the willing group. Logistic regression analysis was conducted to examine trends in the prevalence of current smokers and the proportion of the willing group among current smokers. Results: Overall, 3.7% of Korean men who participated in the study were cancer survivors. Current smokers constituted 19.5%, 19.1%, and 15.3% of cancer survivors in phases V, VI, and VII respectively which did not show significant changes (P for trend=0.33). However, the proportion of current smokers in the non-cancer group was significantly reduced to 46.6%, 41.2%, and 38.9% in phases V, VI, and VII, respectively (P for trend <0.001). The proportion of those with a motivation to quit smoking did not show a significant trend in the cancer survivors (P for trend=0.964) and non-cancer group (P for trend=0.884). Conclusion Prevalence of current smokers and motivation to quit in Korean male cancer survivors did not show significant trends.

BACKGROUND: The purpose of this study was to evaluate the preemptive analgesic effect of a single intravenous infusion of low dose ketamine-clonidine. We compared the placebo with low dose ketamine and low dose ketamine-clonidine in patients undergoing an appendectomy. METHODS: Sixty ASA class 1 or 2 patients who received general anesthesia for an appendectomy were allocated randomly to three groups. Group 1 received intravenous normal saline 6 ml and group 2 received ketamine 0.15 mg/kg in normal saline 6 ml and group 3 received ketamine 0.15 mg/kg and clonidine 1microgram/kg in normal saline 6 ml 5 minutes before surgical incision. In the recovery room postoperative analgesia was assessed by the verbal numerical rating scale (VNRS) at 0 min, 15 min, 30 min, 60 min, 90 min and 120 min. Vital signs, sedation score and side effects were also checked. For postoperative analgesia, morphine 2 mg was given intravenously whenever a patient complained of pain, or the VNRS score was above 7. RESULTS: There were no intergroup differences of individual morphine requirements for postoperative pain control among the three groups. VNRS score, blood pressure, heart rate, sedation score and side effects were not significantly different among the three groups. CONCLUSIONS: A single low dose of ketamine-clonidine may not produce a postoperative analgesic effect in the recovery room, and a single low dose of ketamine also may not produce the preemptive effect for at least 2 hours.

PURPOSE: Conservative management of multicystic dysplastic kidney(MCDK) without nephrectomy has recently been advocated. The purpose of this study was to determine the clinical course of conservatively managed MCDK and to find out possible predictive factors for involution of MCDK by ultrasonography(US). METHODS: A retrospective analysis was made on 46 patients(26 boys and 20 girls) in whom MCDK was detected and had been traced by US between Dec. 1993 and Aug. 2005 at Severance Hospital. RESULTS: Median follow-up time was 30 months(range 2-102 months). All patients underwent radionuclide scans and voiding cystourethrograms. The serial follow-up US showed complete involution in 11(24%), partial involution in 19(41%), and no interval change or increased in cyst size in 13(28%) patients. Nephrectomy was done in 3 patients(7%) due to relapsing urinary tract infection(UTI) and severe abdominal distension. The mean age of complete involution of MCDK was 37 months(range 12-84 months). Episodes of UTI were present in 17 patients(37%) and additional genitourinary(GU) abnormalities were found in 22 patients(44%). Hypertension and renal insufficiency was complicated in one patient. No child developed malignant tumor. Univariate analysis showed that five variables were associated with complete involution of the MCDK; gender, site, UTI episode, additional GU abnormalities, and renal length on initial US. After adjusting using the Pearson model, the presence of additional GU abnormalities was exclusively associated with complete involution among the 5 variables(P=0.034). CONCLUSION: In our review of 46 cases of MCDK, non-surgical approach for patients with MCDK was advisable and we could predict poor prognosis when MCDK is associated with other GU anomalies.

BACKGROUND: A postoperative ileus after anesthesia and surgery may be bothersome to recovery and prolong hospitalization periods. The object of this study was to investigate the effect of lidocaine and ketorolac combined to fentanyl IV PCA on the recovery of bowel function after surgery. METHODS: Forty-nine patients undergoing a total abdominal hysterectomy were divided into three groups (F, FT, LFT). All patients received IV PCA for postoperative pain control. PCA contents were fentanyl 1,000 microgram only in saline 100 ml in group F (n = 16) and fentanyl 500 microgram-ketorolac 150 mg in saline 100 ml in group FT (n = 17) and LFT (n = 16). Group LFT received a lidocaine bolus (1.5 mg/kg) before induction and a continuous infusion of lidocaine (2 mg/min) until one hour after surgery. We measured postoperative pain scores (at postoperative 1 hour, 6 hours, 24 hours, and 48 hours) and checked the first flatus time, the first defecation time, and the side effects. RESULTS: The intravenous lidocaine infusion group showed better pain scores at postoperative 1 hour only. The FT and LFT groups provided a more rapid return of bowel function than group F. A combined infusion of lidocaine and ketorolac had no difference in the return of bowel function. There were no significantly different incidences of nausea, vomiting and other side effects. CONCLUSIONS: Ketorolac allowed an earlier recovery of bowel function after surgery. However, an additional infusion of lidocaine was not helpful in the return of bowel function.
