In the East, Probably one of the most commonly performed esthetic operation is the piercing of the earlobes for earring. the complication of this procedure includes infection, the formation of the hypertrophic scar or keloid, and tearing. Keloid formation is one of the disaterous common complications of the ear piercing. the patients regard the keloid as a cosmetic blemish and they complain that they cannot wear earrings. We have experienced 5 patients of earlobe keloid complicated from piercing of the earlobes. We used intralestional steroid njection, in conjunction with surgical excision and pressure therapy for treatment of the keloid. Among various techniques for reconstructing a piercing, we chose modified Pardue's method for artificial earlobe cleft after wide excision of the keloid. the result was good and satisfactory without any complication after 4 to 24 months of follow-up. the purpose of this paper is to present a simple method of treatment of the earlobe keloid with preservation of the perforation for an earring.

OBJECTIVE: Using Lee et al (1996) model, we assessed the effect of opioid within the PAG on the manifestations of the neuropathic pain, and we studied the effects of naloxone on the analgesic effects of opioid. METHOD: Under pentobarbital anesthesia, male Sprague-Dawley rats were implanted with cannula in the ventral (n=10) and dorsal (n=6) PAG after the unilateral tibial and sural nerves were ligated and cut, leaving the common peroneal nerve intact. Pain sensitivity was assessed using the von Frey filament (8 mN) and acetone applied to the sensitive area for 1 week postoperatively. Rats with neuropathic pain were intracerebrally microinjected with DAMGO (0.1microgram/5microliter) and enkephaline (20microgram/5microliter) into the ventral and dorsal PAG and the pain sensitivity was assessed. Naloxone was injected to assess the observed change of pain sensitivity. RESULTS: Intracerebral microinjection of DAMGO and enkephaline into the ventral PAG, but not the dorsal PAG, increased the pain threshold which was reversed by naloxone. CONCLUSION: The results suggest that stimulation of the ventral PAG in neuropathic rats may reduce neuropathic pain via opioid-mediating pathway of the descending pain inhibition system.

BACKGROUND: Many disinfectants have been used clinically in both single and combination applications, but there have been few studies on disinfective power according to sterilization sequence when using a combination of disinfectants. The purpose of this study was to evaluate the disinfective power of a combination of 70% isopropyl alcohol and 10% povidone-iodine (PVP-I) according to sterilization sequence. METHODS: Two hundred healthy volunteers were recruited. Subjects were disinfected with a combination of 70% isopropyl alcohol and 10% PVP-I on both forearms, in varying sequence. The AP group included disinfections on the left forearm with isopropyl alcohol first followed by 10% PVP-I, while the PA group included disinfections on the right forearm with same disinfectants in reverse order. Skin cultures were obtained using cotton swabs 3 min after application of each disinfectant, and then were inoculated on blood agar plates for bacterial culture. Cultures were incubated at 37degrees C under aerobic conditions for 48 hours. RESULTS: There was no significant difference in the number of positive cultures after the 1st disinfection (AP, 45; PA, 36, P = 0.262) or the 2nd disinfection (AP, 6; PA, 13, P = 0.157), suggesting that there is no relationship between disinfective power and the sequence of the disinfectants used. The number of positive cultures significantly decreased after the 2nd disinfection (P < 0.01), however. CONCLUSIONS: There was no significant difference in disinfective power according to sterilization sequence with 70% isopropyl alcohol and 10% PVP-I in healthy volunteers. The combination of 70% isopropyl alcohol and 10% PVP-I was more effective than disinfection with a single agent regardless of sterilization sequence.

A 33-year old male was admitted due to continuous high spiking fever for 2 months via local clinic. He had been diagnosed pulmonary tuberculosis at local clinic. However, spiking fever had not been controlled by anti-tuberculous medications. Chest PA showed confluent consolidation on right upper & mid-lung field. 5 anti-tuberculous regimens (Streptomycin, Isoniazid, Rifampin, Ethambutol, Pyrazinamaide) were administered initially and steroid therapy was followed for relieving toxic symptoms Very slowly resolved chest X-ray lesion and continuous fever suggested the possibility of misdiagnosis. After 60th hospital day, the chest X-ray lesion was resolved gradually and fever subsided almost completely. He was discharged on 76th hospital day with anti-tuberculous drugs and steroid(prednisolon), without any other problems except sustained mild fever.

PURPOSE: The purpose of the present study was to compare the osteoconduction in porous bodies made of various compositions of calcium phosphate compounds and other porous artificial bones. MATERIALS AND METHODS: Single-level posterolateral spinal fusions were performed on ninety rabbits. The animals were divided into nine groups by graft materials: autograft (positive control), implantation of HA, TCP, CPP, HA/TCP composite, TCP/CPP composite, Lubboc(R) and Calcium sulfate pellet (CSP), no-graft after decortication (negative control). Serial radiography, serum calcium and phosphorus levels were checked. All animals were sacrificed 12 weeks after surgery and the fusion masses were compared by manual palpation, uniaxial tensile strength measurement and histological evaluation. RESULTS: Autografted and CPP implanted groups showed significantly higher fusion ratio than TCP, TCP/CPP composite, and no-graft groups. Meanwhile, HA and HA/TCP groups showed no significant difference with other groups in fusion ratio. From the radiological examination, TCP and CPP groups seemed to show more rapid absorption of implant than HA group. The mean values of tensile strength of autografted and CPP group were significantly larger than those of TCP, TCP/CPP composite, and no-graft groups. The result of direct inspection and microscopic examination showed the TCP-contained implants lost their porous structure, whereas the other implants did not. On the light microscopy, both HA and CPP groups showed more abundant new bone growth into the pores than TCP-contained groups, but the pore size of CPP became larger than that of the HA, which manifested more rapid absorption of CPP in the living body. CONCLUSION: The porous CPP implant is considered to be more desirable bone graft substitute because it has satisfactory osteoconductive ablility and better biodegradation than porous HA. And the maintenance of porous structure is considered to be indispensable for osteoconduction.

BACKGROUND: The purpose of this study was to investigate the changes in airway pressure and arterial oxygenation between ventilation modes during one-lung ventilation (OLV) in patients undergoing thoracic surgery. METHODS: We enrolled 27 patients for thoracic surgery with OLV in the lateral decubitus position. The subjects received various modes of ventilation in random sequences during surgery, including volume-controlled ventilation (VCV) and pressure-controlled ventilation-volume guaranteed (PCV-VG) with a tidal volume (TV) of 8 ml/kg of actual body weight. Target-controlled infusion (TCI) with propofol and remifentanil was used for anesthesia induction and maintenance. After double-lumen endobronchial tube (DLT) insertion, the proper positioning of the DLT was assessed using a fiberoptic bronchoscope. Peak inspiratory pressure (Ppeak), exhaled TV, and arterial blood gas were measured 30 min after each ventilation mode. RESULTS: P(peak) was significantly reduced with the PCV-VG mode (19.6 +/- 2.5 cmH2O) compared with the VCV mode (23.2 +/- 3.1 cmH2O) (P < 0.000). However, no difference in arterial oxygen tension was noted between the groups (PCV-VG, 375.8 +/- 145.1 mmHg; VCV, 328.1 +/- 123.7 mmHg) (P = 0.063). The exhaled TV was also significantly increased in PCV-VG compared with VCV (451.4 +/- 85.4 vs. 443.9 +/- 85.9 ml; P = 0.035). CONCLUSIONS: During OLV in patients with normal lung function, although PCV-VG did not provide significantly improved arterial oxygen tension compared with VCV, PCV-VG provided significantly attenuated airway pressure despite significantly increased exhaled TV compared with VCV.
