BACKGROUND: Whether or not the excitation-contraction (EC) uncoupler, diacetyl monoxime (DAM) and cytochalacin D (Cyto D) alter the ventricular fibrillation activation patterns is unclear. METHODS: We recorded single cell action potentials and performed optical mapping in isolated perfused swine right ventricles at different concentrations of DAM and cyto D during ventricular fibrillation and dynamic pacing. RESULTS: Increasing concentration of DAM results in progressively shortened action potential duration measured to 90% repolarization (APD90), reduced slope of the action potential duration restitution(APDR) curve, decreased Kolmogorov-Sinai entropy, and reduced number of ventricular fibrillation wavefronts. In all right ventricles, 15 to 20 mmol/l DAM converted ventricular fibrillation to ventricular tachycardia. The ventricular fibrillation could be reinduced after the DAM was washed out. In comparison, cyto D (10 to 40 mol/l) has no effects on APDR curve or the dynamics of ventricular fibrillation. The effects of DAM on ventricular fibrillation are associated with reduced number of wavefronts and dynamic complexities in ventricular fibrillation. CONCLUSION: These results are compatible with Restitution Hypothesis of ventricular fibrillation and suggest that DAM may be unsuitable as an EC uncoupler for optical mapping studies of ventricular fibrillation in the swine right ventricles.

BACKGROUND: Peripheral blood stem cell transplantation in children has some difficulties compared with adult cases. Despite the children's total blood volume is small, they have a relatively higher volume of blood per weight than adults. Also, it is hard for the children to maintain 2 central vein during leukapheresis to shorten the time consumed. We compared the artery-harvest and central vein-harvested group for possible risk and stem cell yield in pediatric patients with malignancies. METHODS: From August, 1995 to January, 1997, 21 leukapheresis was performed by 7 patients. The patients who could have 2 central veins for leukapheresis were included in vein-harvested group and the patients who could have only 1 central vein were included in artery-harvested group. The peripheral vein was not used for leukapheresis. COBE Spectra(COBEBCT, Lakewood, CO) was used and priming was done by packed RBCs in patients weighing less than 20kg. Stem cell yield was assessed by MNC, CD34+, CFU-GM, respectively. During leukapheresis, the patients were closely monitored for change in vital sign, evidence for thrombosis, bleeding, hypocalcemia, etc. RESULTS: There was no serious complication in each group of patients. After the leukapheresis, WBC and platelet count decreased but Hb level was increased due to reinfusion of primed packed RBCs. Average flow rate was higher in vein-harvested group but there was no difference in time consumed and results in stem cell assay. CONCLUSION: Peripheral stem cell harvest in children by radial artery can be performed safely and easily without an increased risk or complication. In younger children, it is possible to achieve even more higher stem cell yield. If the patient is unable to maintain 2 central vein for leukapheresis, transient radial arterial catheterization is a safe and convenient method.

Allergic contact dermatitis from aroma oils has long been recognized and with increasing frequency. Contact dermatitis of the allergic type of fragrances used for aromatherapy has been reported rarely, and only in patients exposed due to their occupation. We report herein a case of allergic contact dermatitis to aroma oils in an aroma therapist. A 25-year-old woman, an aroma therapist, had been treated with topical steroids under the impression of contact dermatitis. She had had pruritic erythematous maculopapules on the arms extending to the hands for the previous 6 months. Patch tests showed strong reactions to aroma oils(3% fennel and 3% juniper). The skin lesions were cleared after she stopped her job. However, re-exposure to aroma oils caused eczematous lesions repeatedly at the sites previously involved. We predict that increasing popularity of aromatherapy will lead to increasing number of patients developing allergic contact dermatitis from aroma oils. This has to be taken into consideration when testing patients with suspected contact dermatitis.

Adhesion around tendons of the hand and wrist and subsequent limitation of motion, is one of the major complications after tendon surgery. In addition to the tendon surgery such as tendon repair or graft, infection, open reduction of fracutres, and burn scar contracture could be the casuses of tendon adhesion. Tenolysis and adequate postoperative rehabilitation program, has been proved to be effective in preventing of adhesion, whatever the cause may be, if its continuity is maintained. In order to evaluate the efficiency and problems of tenolysis, we reviewed 37 fingers of 31 patients who had been treated by tenolysis at Seoul National University Hospital from 1981 to 1991. There were 20 men and 11 women, and the average age was 28.2 years(9-45 years). The causes of adhesion were various; 24 fingers(64%) after tendon repair or tendon graft, 3 fingers(8%) after infection, 4 fingers(10%) after treatment of fracture, 4 fingers(10%) after burn scar contracture, and the other 2 fingers(5%) after curettage of enchondroma. Involved tendon were flexor tendon in 28 fingers and extensor in 9. The average duration of follow-up was 17 months(13 months to 4 years). Active motion of involved finger was started within 2 days after operation. The Total Active Motion(TAM) after operation was average 213°(100°-260°), compared to 123°(40°-180°) before operation. According to Strickland formula which was modified by us, the postoperative results were excellent in 17 fingers, good in 9 fingers, fair in 6 fingers and poor in 5 fingers. In 24 cases who had tenolysis after repair or graft, 19 case(79%) were rated as excellent or good. But in 7 cases whose causes of adhesion were infection or burn scar contracture, only 3 cases(42%) were rated as excellent or good. Compairing the results between younger(less than 30 years of age) and older(more than 30 years of age) group, the younger group showed excellent and good in 8496 and the older group in 41%, The complications were tendon rupture in 3 fingers and minor infection in 2 fingers, respectively. In summary, tenolysis was considered as a useful procedure to improve function of tendon bound down in scar tissue. And the results were better in younger age group(p < 0.05) and in previous tendon repair or graft(p < 0.05) group.

Carpal tunnel syndrome is the most common peripheral nerve entrapment syndrome due to compression of the median nerve at the wrist. Division of the transverse carpal ligament for median nerve compression in patients with carpal tunnel syndrome is a common and successful procedure. A variety procedures exist to release the transverse carpal ligament the classic open release, limmited open or percutaneous release, and endoscopic release. From February 1994 to January 1996, 39 carpal tunnel releases were performed by percutaneous method in 30 patients (3 males and 27 females) at the Chonnam University Hospital. The patients age ranged from 42 to 67 years (average 54.8 years). The duration of the symptoms ranged from 3 months to 10 years. According to Brown's outcome analysis, results were as follows. 1. Persistent pain and paresthesia were noted in only 3 cases (7.7%) at 24 week postoperatively. 2. Two-Point discrimination on the index finger was improved significantly at 12 week postoperatively (p<0.05). In electromyographic study, conduction delay of motor and sensory fibers was diminished significantly at 4 week postoperatively (p<0.05). 3. Functional outcomes (grip strength, pinch strength, scar tenderness and return to work) were showed good and excellent result. We concluded that percutaneous decompression is one of the less morbid method for decompressing the carpal canal and relief of symptoms for the patient.

Background: Facial rejuvenation techniques using thread lifts are performed by passing sutures under the facial skin to treat sagging and facial flaccidity, and their advantages include a relatively short recovery time and relatively small incisions. In this study, we describe the short-term safety of a facial rejuvenation technique involving an absorbable polydioxanone monofilament thread (Mint Lift) in patients with mild-to-moderate facial skin sagging. Methods: The current multicenter, retrospective, case-series study was conducted in a total of 196 patients who visited the Grace Plastic Surgery Clinic or the Songdo IB Clinic between 2016 and 2018. The patients underwent insertion of the Mint Lift 43 and 17 in the deep temporal fascia and the deep subcutaneous layer, respectively. Of these patients, 179 met the eligibility criteria and their medical records were retrospectively reviewed. Results: The patients comprised six men (3.4%) and 173 women (96.6%), with a mean age of 44.4±14.4 years. In our series, postoperative complications included ecchymosis (1.7%), infection (0.4%), thread extrusion (1.1%), and skin dimpling (1.5%). No cases of iatrogenic nerve injury were observed, and all postoperative complications spontaneously resolved. Conclusions The Mint Lift 43 and 17 may be safe for thread lifting in patients with mildto-moderate facial skin sagging. However, further long-term follow-up studies are warranted.

PURPOSE: Early detection of appendicitis has increased due to development of computed tomography and ultrasonography, yet we are frequently meeting complicated appendicitis, including perforation, abscess and a gangrenous appendicitis due to delayed diagnosis. For that reason, we want to evaluate predictive factors for the complicated appendicitis. METHODS: A total of 128 patients with appendicitis, after 13 patients with a duration of under 12 hours and 15 patients with pathological non-appendicitis were excluded from 156 patients, who visited Kwangju Christian Hospital from November 2008 to November 2010 were retrospectively reviewed. RESULTS: There were 62 patients (48.3%) with simple appendicitis and 66 patients (51.7%) with complicated appendicitis. In univariate analysis, age (P < 0.001), C-reactive protein (P < 0.001) and the diameter of the appendix (P = 0.006), were found to be significant. Multivariate analysis demonstrated that C-reactive protein was an independent predictor for complicated appendicitis (odds ratio, 1.371; 95% confidence interval, 1.155 to 1.628; P < 0.001). The cut-off value of C-reactive protein was set at 7.05 mg/dL by using receiver operating characteristic curve (0.805; sensitivity, 57.6%; specificity, 98.3%). CONCLUSION: This study suggests that if C-reactive protein is above 7.05 mg/dL, immediate and proper management should be performed due to a high probability of complicated appendicitis, especially in young children or elderly patients who frequently present with vague symptoms.

BACKGROUND: Efficacy of percutaneous transluminal angioplasty(PTA) in the treatment of Peripheral arterial disease has been established. Complications such ans PTA-induced dissections or residual stenosis with occasional mural thrombi have been reported, which compromise the results. New procedures can be used in combination with PTA to improve the immediate and long term results, such ans prolonged balloon inflation, atherectomy, or implantation of endovascular prosthesis. In addition, the occurrence of other lesions, such as spontaneous or post-catheterization dissection or post-PTA restenosis, has prompted the insertion of a vascular stent. But there was few reports on stenting for peripheral arterial disease in Korea. METHODS: To evaluate the safety, efficacy and stability of stent in peripheral arterial disease, twenty-six consecutive symptomatic patients with 37 peripheral lesions were treated with 39 balloon expandable(33 Strecker and 6 Palmaz)stents with or without prior balloon angioplasty in the period of March 1991 and February 1994. RESULTS: The major cause of disease was arteriosclerosis(22 out of 26). The implantation sites for our study include 22 in common iliac artery, 11 in external iliac artery 2 in aorta, subclavian artery, superficial femoral artery each other. Indication for stent deployment were primarily suboptimal results(19 lesions), insufficient PTA such as dissections(4), restenosis after previous PTA(2), and primary stenting was performed without preceding therapeutic PTA(10). Stent deployment was technically successful in 24 of the 26 patients(92%) and clinical success rate was in 25 of the 26 patients treated(96%). Hemodynamic change revealed markedly improvement before and after stenting(peak pressure difference from 66.329.0mmHg to 9.1+/-7.1mmHg; Mean pressure difference from 33.0+/-22.5mmHg to 4.7+/-4.3mmHg). There were two procedural complications which included one stent migration and one artery perforation. During the 7 months of follow-up(1-18 momths), two restenosis occurred. One patient died due to cerebral hemorrhage during thrombolysis with urokinase. CONCLUSION: The stent deployment is relatively safe and very effective primary therapeutic modality and may abolish the limitation of PTA such as suboptimal result, dissection with sudden occlusion and restenosis in peripheral vascular disease and highly recommended in selected cases.
