The recent discovery of plasmid derived beta-lactamase production by N. gonorrhoeae has changed the outlook of treatment of gonococcal infections and may well become the single most important factor in gonorrhoea control. Penicillinase is a beta-lactamase that splits the beta-lactam ring of penicillin hetween the C and N atoms to form penicilloic acids. We have been trying to assess the prevalence of PPNG in Korea since May 1980. We report here 7 strains of beta-lactamase producing N. gonorrhoae detected by chrornogenic cephalosporin method from Jan. 1981 to Mar. 1981 at the Joong Ku puhlic health center in Seoul. In January, I strain (l.3%); February, 2 strains (5.0%); and March, 4 strains .(6 4%) have been isolated. All restrains were confirmed by sugar feriventation test. Previously only one strain of PPNG had been reported among Korean laymen. The sudden appearance of PPNG among Korean laymen in 1981 may mean the barruer between U.S. Army enc1aves and Korean public has been broken recently and/or direct irnport of PPNG frorn abroad especially from South East Asia.

FISH is suggested as a possible method to detect the numerical and structural abnormalities of chromosomes in interphase nucleus. We performed this study to discuss the clinical usefulness of FISH in uncultured amniocytes and to set up the cut-off value for further study. We collected amniotic fluid samples from patients whose chromosome studies were recommended due to screen positive for Down and Edword syndrome in triple marker test using maternal serum. The centromeric probe for chromosome 18 and the locus-specific probe for chromosome 21 were used and the results were compared to their karyotypes. We could find 2 cases of trisony 21 and 2 cases of trisony 18 and the other cases represented normal karyotypes. The accuracies were 91% for disomy 18, 89% for trisomy 18, 92% for disomy 21 and 88% for trisomy 21. Therefore FISH technique is a possible method to detect the chromosomal abnormalities in uncultured amniocytes and the use of locus-specific probe for chromosome 21 would be more useful for detecting the aneuploidy of chromosome 21 than 13/21 centromeric probe.

OBJECTIVE: To determine the fetal aneuploidy in fetal blood cells from cordocentesis. METHODS: We analyzed their karyotype and performed fluorescence in situ hybridization(FISH) for chromosome 18, 21, X, and Y in 14 cases of fetal blood cells from cordocentesis at Department of Obstetrics & Gynecology, College of Medicine, Seoul National University and Hamchoon Women's Clinic. RESULTS: In all cases we obtained the consistent results in both methods and were able to rapidly detect aneuploidy in uncultured fetal blood cells using FISH before karyotyping with culture for 48 hr. The averages for accuracy of FISH were from 84.6 % to 93.9%. CONCLUSION: In this study we suggest that the rapid detection in uncultured fetal blood using FISH is possible and that this diagnostic method will be clinically useful when rapid result would be demanded.

The authors have experienced a case of extrascleral extension of choroidal malignant melanoma. The patient has suffered from the ocular pain and proptosis of right eye. We performed Kronlein operation under the clinical impression of the retrobulbar mass and obtained the histopathological diagnosis of malignant melanoma. Fifteen days after the operation, we performed exenteration and the rotation flap of temporalis muscle was inserted into the right eye ball socket through the lateral wall of the orbit.

OBJECTIVE: To investigate cortical reorganization of the brain during voluntary activities of the hand in patients with subcortical cerebral infarction. METHOD: Twelve patients with first-ever subcortical brain lesion causing hemiparesis had been evaluated with functional MRI. Bilateral hand clenching was done to test voluntary hand activities. Recovery period ranged from 2 to 36 months. RESULTS: During the unaffected hand movement, activation of contralateral primary sensorimotor cortex (SMC) were recorded in all cases and supplmentary motor area (SMA) in 1 case. The affected hand movement showed activation of the cotralateral SMC in all cases, ipsilateral SMC in 4 cases, SMA in 4 cases and contralateral prefrontal area in 2 cases. As for the contralateral SMC, affected hand movement showed more increased activation than the unaffected. For the bilateral SMC activation during movement of the affected hand, contralateral SMC activation was greater than the ipsilateral. CONCLUSION: Ipsilateral activation of the SMC, SMA, prefrontal area and increased activation of the contralateral SMC during affected hand movement suggest that these may play an important role in the reorganization of sensory and motor system in stroke patients with subcortical lesion. Functional MRI studies of patients who recovered from subcortical stroke provide evidence for several process that may be related to restoration of neurologic function.

OBJECTIVE: To investigate the effect of environmental factors on the ability of mobility in subjects with chronic stroke who can perform nearly independent activities of daily living (ADL). METHOD: Sixty one patients were divided into three groups (superior, middle, and inferior) by the degree of independent walking. Modified self-administered questionnaire was completed to report how well the patients encountered the environmental elements faced in community mobility. In addition, all patients were assessed to find out the difference of ADL performance, Berg balance scale (BBS), 10 m walking time (10 mWT) and patterns of 'going out' among the three groups. RESULTS: The group 1 (superior group) had shown better performance than group 2 (middle group) and group 3 (inferior group) in performance of ADL, BBS, 10 mWT. Secondly, the group 1 visited more places or destinations per day than the group 2 and 3, and they used more various transportation systems than other groups. Finally, there were significant differences in the distance dimension, the temporal dimension, terrain dimension (except for a 'getting on a elevator' component), and density dimension among the groups. CONCLUSION: Environmental factors as well as functional abilities could affect the mobility of subjects with chronic stroke. This result suggests that any kinds of compensation and the supports of social institutions are needed even in subjects of nearly independent ADL for their improvement of mobility and convenience.

PURPOSE: DC cardioversion is the treatment choice for atrial fibrillation and flutter. Because of the high voltage power across the thorax, most patients suffer some degree of superficial erythema or burn at the pad site. 2nd or 3rd degree burn and muscle necrosis is very rare after shock. We experienced one case of 3rd degree burn with ulceration after DC cardioversion. METHODS: A 44-year-old male was admitted to local hospital with the presenting palpitation and atrial fibrillation on ECG. During radiofrequency catheter ablation (RFCA) for the treatment of atrial fibrillatoin, DC cardioversion was performed. The patient did not complain of any pain or discomfort at the pad site during or immediately after the procedure. Approximately 14 days after the shock, he had blisters at the pad site. But he received simple dressing treatment at the local hospital for 6 months. When he visited our burn clinic, there was 3x5 cm sized 3rd degree burn with eschar and necrotic fat tissue at the pad site of right back. Surgical removal of a necrotic tissue was performed on the patient by STSG (Split thickness skin graft) with Matriderm(R). RESULTS: Muscle fascia was exposed after debridement of the necrotic skin and fat tissue. The skin graft was well taken within 2 weeks after operation. CONCLUSION: In case of using monophasic 360 J, approximately 3,000 V energy is discharged. The energy is sufficient to cause burn injury to skin. Damage may result both thermal burn and electrical burn. The burn degree in the electric circuit is proportional to amperage and time, is inversely proportional to pad site area. We therefore suggest that in order to reduce deep burn, DC cardioversion is started with lower energy shocks, proper pad placement and correct pad application is important. And we give a notice that deep pad burn possibly occur after the cardioversion procedure.

PURPOSE: In cases of high voltage electrical burns, a wound occurs as current enters or leaves the body and is accompanied by deep tissue injury. If upper extremity amputation is inevitable, consideration should be given to the residual limb functions, secondary reconstruction, and wearing of an upper prosthesis. Our hospital has achieved satisfactory outcomes through the use of a pedicled latissimus dorsi (LD) flap in patients undergoing transhumeral amputation and shoulder disarticulation due to upper extremity damage from high voltage electrical burns. METHODS: The study was targeted to five patients who suffered high voltage electrical burns, underwent above-elbow amputation, and were reconstructed in the acute and secondary phases using a pedicled LD flap from January 2005 to December 2011. All patients underwent equilateral pedicled LD flap surgery, with primary closure at the donating site. RESULTS: The average age of patients was 49.6 years (38~64); they were all male. One patient underwent sublayer skin grafting after a pedicled muscular LD flap, and four patients had a pedicled myocutaneous LD flap: one patient among the four had a forearm flap after the pedicled myocutaneous LD flap. All flaps were well adhered, and post-surgical flap reduction and local flaps were performed for adequate sizing and aesthetic improvement. CONCLUSION: In cases of upper arm amputation due to wide upper extremity damage caused by electrical burns, the use of the pedicled LD flap and adequate amputation length made subsequent wearing of a prosthesis possible. The pedicled LD flap procedure allowed reconstruction of a relatively large area of soft tissue and the surgery to the donating site was unproblematic.

PURPOSE: The use of the Ondol, which is a traditional Korean floor heating system, has made the electric heating pad popular in Korea. Although the surface temperature of electric pads is around 45 degrees, rarely they can cause severe contact burns. Because an electric pad is usually used while sleeping, the skin could be exposed to heat and pressure for a prolonged period. The purpose of this study was to investigate the epidemiology and clinical features of these types of burns and to advise caution in the use of electric heating pads. METHODS: We performed a retrospective analysis of 58 cases identified from March 2007 to March 2012 at the Hangang Sacred Heart Hospital plastic surgery department. Collected data included sex, age, seasonal variation, distribution and extent of the burn, underlying disease, related factors, and treatment. RESULTS: Patients (23 females and 10 males) were predominantly in their twenties, with an average age of 40.7 years (range, 14~83). The majority of the burns occurred during winter (51.5%). According to the patients' histories, sleeping in a drunken state was the most common associated factor, with taking hypnotics and lying under spinal anesthesia being the second and third factors, respectively. Eight patients had diabetes mellitus and four patients had hypoesthesia after spinal cord injury and cerebral stroke. The lower extremity was the most commonly involved site (42.4%), followed by the buttocks (33%). The extent burn areas accounted for less than 2% of the total body surface area. But deep second degree and third degree burns were sustained that required surgical intervention. CONCLUSION: Unconsciousness and hypoesthesia were the primary factors that provoked contact burns related to the use of electrical pads. Although the percentage of body surface area burns is often small, the burns caused by electric pads can cause deep thermal injuries, necessitating the use of skin grafts and local flaps. These injuries could be prevented by taking precautions when using electric pads and by educating the public.

OBJECTIVE: Surgical treatment of posterior inferior cerebellar artery (PICA) aneurysms is challenging due to limited surgical accessibility. Endovascular approach has a benefit of avoiding direct injury to the brainstem or lower cranial nerves. Therefore, it has recently been considered an alternative or primary modality for PICA aneurysms. We retrospectively assessed outcomes following detachable coil embolization of saccular PICA aneurysms. METHODS: From February 1997 to December 2007, we performed endovascular procedures to treat 15 patients with 15 PICA aneurysms. Fourteen patients with 14 PICA aneurysms morphology of which was saccular were reviewed retrospectively. Twelve patients had ruptured aneurysms. The aneurysms arose from the PICA origin site (n = 12), the PICA lateral medullary segment (n = 1), or the PICA tonsilomedullary segment (n = 1). RESULTS: Complete aneurysm occlusion was achieved in 10 patients, residual neck in 3, and residual sac in one. Radiological follow-up was performed in 7 patients with mean duration of 34.7 months (range, 1-97 months) and showed stable or complete occlusion in 6 patients. There were no rebleeding or retreatment after endovascular treatment. Thromboembolism was the only procedure-related complication (n = 4 ; 28.6%). Asymptomatic PICA infarction occurred in two patients and symptomatic PICA infarction in two elderly patients with poor clinical grade. Of these procedural PICA infarction cases, 1 symptomatic PICA infarction patient developed ventriculitis and septic shock leading to death. The clinical outcome was good in 10 patients (71.4%). Conclusions: In the present study, detachable coil embolization has shown as an efficient modality for PICA saccular aneurysms challenging indications of microsurgery. However, thromboembolic complications should be considered, especially in poor clinical elderly patients with ruptured aneurysms.
