A clinico-pathological study on the true skin appendage tumors was carried on the accumulated cases during pat 11 years from 1976 to 1986 years in the Department of Pathology, Seoul National University Hospital. The results was as follows; 1) Among various benign skin appendage tumors pilomatricoma was the most common benign tumor consisting of 72 out of 244 cases (30.1%), followed by dermoid cyst 48 cases (20.0%), steatocystoma multiplex 37 cases (15.5%), syringoma 33 cases (13.8%) and trichilemmal cyst 19 cases (0.8%). Other benign skin appendage tumors were rarely noted under 3%. Sebaceous carcinoma was most common among malignant skin appendage tumors and no malignant tumor of sweat gland origin was noted. 2) The sex ratio of male to female of the pilomatricoma was 1 : 2.6 and on the face, neck, and extremeties in 1st and 2nd decades. The sex ratio of dermoid cyst was 1 : 1.2 on the face in 1st decade. The sex ratio of steatocystoma multiplex was 1 : 1.9 and on the trunk in 3rd decade. The sex ratio of syringoma was 1 : 7 and on the face in 5th decade. The sex ratio of trichilemmoma was 1 : 1.6 and on the trunk in 5th decade. Other tumors were not avaiable for analysis because of small number. The sex ratio of sebaceous carcinoma was 1 : 2 and on the eyelid in 6th decade

5.Current Opinion on Endovascular Therapy for Emergent Large Vessel Occlusion Due to Underlying Intracranial Atherosclerotic Stenosis
Korean Journal of Radiology 2019;20(5):739-748
For recanalization of emergent large vessel occlusions (ELVOs), endovascular therapy (EVT) using newer devices, such as a stent retriever and large-bore catheter, has shown better patient outcomes compared with intravenous recombinant tissue plasminogen activator only. Intracranial atherosclerotic stenosis (ICAS) is a major cause of acute ischemic stroke, the incidence of which is rising worldwide. Thus, it is not rare to encounter underlying ICAS during EVT procedures, particularly in Asian countries. ELVO due to underlying ICAS is often related to EVT procedure failure or complications, which can lead to poor functional recovery. However, information regarding EVT for this type of stroke is lacking because large clinical trials have been largely based on Western populations. In this review, we discuss the unique pathologic basis of ELVO with underlying ICAS, which may complicate EVT procedures. Moreover, we review EVT data for patients with ELVO due to underlying ICAS and suggest an optimal endovascular recanalization strategy based on the existing literature. Finally, we present future perspectives on this subject.

Background: The highly lipid soluble opioid, fentanyl, has a rapid onset and short duration of action. The present study was designed to examine the analgesic efficacy and side effects of the combination of fentanyl with morphine in patients using intravenous PCA. Methods: Patients were randomly assigned to receive one of three PCA regimens: M4 group (40 mg morphine+90 mg ketorolac+1.5 mg dorperidol), M2F2 group (20 mg morphine+200 ug fentanyl+90 mg ketorolac+1.5 mg dorperidol), or M2F4 group (20 mg morphine+400 ug fentanyl+90 mg ketorolac+1.5 mg dorperidol). All patients were given initial loading dose of 0.1 mg/kg morphine plus 1 mg droperidol at the end of surgery. Pain score, side effects, and overall satisfaction were assessed at 30 min, 1 hr, 8 hr, 24 hr, and 48 hr postoperatively. Results: The pain score was significantly higher in the M2F2 group than in the M4 group and M2F4 group during 1 hr and 8 hr postoperatively. The total opioid consumption was significantly greater in the M2F4 group than in the M4 group. Patient satisfaction was better in the M2F4 than other two groups. There were no differences in the overall incidence of side effects among three groups. Conclusions: The present results suggest that the combination of fentanyl with morphine for intravenous patient-controlled analgesia is a useful method, and the double dose of fentanyl in comparison with the equipotent morphine dose is recommended in the early postoperative period.

BACKGROUND: Clean dermatologic procedures create wounds with a low risk of infection (usually up to 5%). Whether the use of topical antibiotics is advocated, with regard to its efficacy and safety issues such as antibiotic resistance and sensitizing potential, is controversial. Fusidic acid, a topical antibiotic against gram-positive bacteria, is a rare sensitizer and commonly used in postprocedure care in Korea. OBJECTIVE: This is a retrospective study aimed at comparing the efficacy and safety between fusidic acid and petrolatum for the postprocedure care of clean dermatologic procedures. METHODS: Patients were treated with either fusidic acid or petrolatum ointment, applied on the wound created during clean dermatologic procedures such as biopsy of the punch, incisional, excisional, and shave types. The efficacy, adverse events, and subjective level of satisfaction were retrieved from medical records. RESULTS: A total of 414 patients with a total of 429 wounds were enrolled. The overall rate of adverse events was 0.9%, and the rates of adverse events in the fusidic acid group and the petrolatum group were 1.4% and 0.5%, respectively (p=0.370). There was no wound discharge, pain, tenderness, swelling, induration, or dehiscence in both groups. The patients' self-assessment of the wound was not significantly different between the two treatment groups. CONCLUSION: Our findings support the hypothesis that the routine prophylactic use of topical antibiotics is not indicated for clean dermatologic procedures. We recommend the use of petrolatum in the postoperative care of clean dermatologic procedures because of its equivalent efficacy and superior safety profiles.

The surgical methods of injured peripheral nerve were limited to end-to-end neurorrhaphy, nerve graft, neurotization, etc. Recently, Several studies were executed about end-to-side neurorrhaphy in peripheral nerve injury. The purpose of this study is to investigate the axonal regeneration of end-to-side neurorrhaphy in rats, as alternative surgical method for peripheral nerve injury comparing with the state of normal, denervated, and end-to-end neurorrhaphy. Sixty female Sprague-Dawley rats were divided into four groups; group I as normal control group, group II as denervated control group, group III as end-to-end neurorrhaphy group, group IV as end-to-side neurorrhaphy group. At postoperative 4, 8, 12, 16, 20 and 24 week, nerve regeneration was assessed through electrophysiologic and histological studies. The results obtained were as follows: 1. In electrophysiologic test, the mean amplitude was higher in normal control group(group I) than either in end-to-end neurorrhaphy group(group III) or in end- to- side neurorrhaphy group(group IV)(p < 0.05). But there is no significant difference between group III and group IV. 2. The mean number of regenerating myelinated nerve fibers was higher in group I than either in group III or in group IV(p < 0.05). But there is no significant difference between group III and group IV, except at postoperative 16 week. 3. The mean number of motor end-plates at postoperative 24 week was 20.5 in group III and 18.2 in group IV, but there is no significant difference between group III and group IV. In conclusion, end-to-side neurorrhaphy through an epineural window could induce distal nerve regeneration by collateral sprouting of main peripheral nerve and positively reflected in functional improvement of the target muscle.

We experienced a case of postoperative quadriparesis secondary to operative position in a patient with pre-existing, asymtomatic,cervical neurilemmoma. The patient was admitted with chronic otitis media for mastoidectomy on right side. There was no specific event throughout operation and anesthesia but developed quadriparesis one hour after arrival on ward. With magnetic resonance imaging, the patient was dignosed to have cervical neurilemmoma. On seventh postoperative day the patient had second operation,cervical laminectomy and tumor removal. Ten days after second operation he was discharged without any complication. Eight months later he had mastoidectomy on the left side and was discharged without any sequale.

BACKGROUND: Nausea, vomiting are among the most common postoperative complaints. We compared the effects of dexamethasone with or without propofol to the effects of conventional regimen consisting of enflurane-N2O in the prevention of postoperative nausea and vomiting. METHODS: Eighty healthy children, aged 3~14 yr, undergoing elective tonsillectomy were alldegrees Cated randomly to receive either 67% nitrous oxide and 1.5~2.0% enflurane or 67% nitrous oxide and propofol infusion 6~10 mg/kg/hr for maintenance of anesthesia. Dexamethasone 150 microgram/kg(maximum dose 8mg) or placebo was administered intrvenously(IV) in a double-blinded fashion before surgery. RESULTS: Dexamethasone reduced the overall incidence of vomiting from 45%(control) to 10%, Propofol also reduced from 45% to 15%. Combination of propofol anesthesia and dexamethasone administration reduced from 45% to 10%. CONCLUSIONS: Dexamethasone and propofol markedly decreased vomiting in healthy children after elective tonsillectomy.
