Recently, the frequency of meniscal injury of knee has been increasing due to increase of sports activities. It has been known that bucket handle tear is the most common type of the entire injuries of the meniscus. We found 127 cases of meniscal tears and experienced 42 cases of bucket handle tears in the arthroscopic findings from Jan. 1991 to April 1994 in our hospital. We analysed 31 cases which were followed up for at least 1 year. The purpose of this study is to analyse the locking history and frequency, to discuss the several types of bucket handle tear in arthroscopic view, to introduce three portal techniques using posteormedial or posterolateral portal to resect the meniscus, and to analyse our clinical results. So we concluded as follows. 1. Among the 31 cases, 23 cases(74%) had an episode of locking. 2. We found many different types of bucket handle tears in arthroscopic view and the most common type was complete tear in a classic type(11 cases). 3. We were able to resect the meniscal fragment very easily using posteromedial or posterolateral portal. 4. We obtained satisfactory results in 24 cases(77%).

Augmentation mammoplasty can be done in various manners according to the way of approach. the type of implant or implatation site depending on the status and demand of the patients or the operator's preferrence. In reviewing the many published reports about augmentation mammoplasty, they compare their surgical outcomes with mixed factors, so it is difficult to compare the results of mammoplasty simply with one factor under the same conditions. We think that analyzing the surgical results with one consistent method enables to compare and decide the influencing effect of one factor within it in augmentation mammoplasty. We could find the fact that the Korean women who wanted augmentation mammoplasty had same physical characteristics and demands, so developed the standardized method of augmentation mammoplasty among those debatable data for the purpose of increasing the patients' satisfaction, decreasing the complications, and shortening the operation time. The method we adopted was placing the implant through transaxillary subpectoral approach and using the endoscope auxiliarily in additional dissection and hemostasis. We employed saline-filled implants of round, textured type with the size ranging fro 125cc to 175cc and overinflated them by 10 to 30% beyond its original volume. After irrigation of the dissected pocket, we placed the suction drainage system into the subpectoral pocket. We educated the patients to massage their breasts right after removal of the drain. During the period of follow-up (from 6 months to 24 months), most of the patients were satisfied with their operative results. Though we experienced one case of capsular contracture, one case of malposition of the implant, and three cases of scar contracture on axillar incision site, as a whole, we could minimize the complications associated with augmentation mammoplasty. We present our postoperative results with the conclusion that our standardized method of augmentation mammoplasty can bring results of high satisfaction rate, minimal complication, predictability of postoperative results, shortening of operation time when applied consistently to the Korean patients whose physical characteristics are similar. We also hope that stanadardized method can be used to compare the influencing effect of many factors in the case of changing one factor within the standardized in the future follow up period.

In analyzing the postoperative results or evaluating the velopharyngeal incompetence after palatoplasty, speech evaluation is the inevitable factor. However, a standardized method for evaluating the speech problem in Korean cleft palate patients has not been available until now. So, the authors tried to establish a method of speech evaluation which is simple, economic and applicable to young patients, and to make a scoring method of the speech results in cleft palate patients based on the 'hypernasality diagnosing tool for cleft palate patient (OK Ran Jung)' which is commonly used by domestic speech therapists. The authors adopted the 'hypernasality diagnosing tool for cleft palate patients (OK Ran Jung)' male and female of children and adults, each consisting of 10 patients and make them speak according to the items about hypernasality and misarticulation evaluation, and record the results. We also calcuted the degree of the formants of the vowels (/a/, /o/, /u/)using sound spectrography. We examined the interjudge and intrajudge reliance of speech evaluation among the 10 inverstigators, revised the evaluation tool, devised the scoring method according to the above results, and compared the scoring results with those of sound spectrography to prove the reliance of our speech evaluation tool. With the scoring method, the authors could estimate the degree of hypemasality and misarticulation in cleft palate patients with evidence of reliability based on point-to-point agreement in two items. In comparing the results of our scoring method with the formant of vowels using sound spectrography, staistical significance existed except /u/F2 and that meant that our scoring method was reliable. We suggest that this simple, economic and reliable method of speech evaluation in cleft palate patients can create the basis for speech evaluation in patients of cleft palate and velopharyngeal incompetence under circumstances in which the results of various speech treatments are evaluated in comparison to various methods of speech evaluation.

Many methods of correcting secondary cleft lip nose deformity have been introduced, but a single best method that can be uniformly adjusted for all cases does not exist. Since it is difficult to make the nostril of the cleft side symmetric with that of normal side, the authors tried to formulate the basis for correction of unilateral secondary cleft lip nose deformity according to the varying amounts of deformed nostril. We then adopted 4 different methods of correcting the soft tissue and nostril deformity in 63 patients from 1996 to 1998 and surveyed the results. Our principles were as follows: 1) Alar rim incision was done in cases of different-shaped cleft-side nostrils with nearly the same measured area in comparison to the normal side. 2) When deformity of the alar-columellar web was severe, we performed modified Z-plasty. 3) When the nostril of the cleft-side nostril was smaller than the normal side with slight asymmetry, reverse W-plasty was done. 4) We adopted a reverse-U incision when there was a discrepancy in height with moderate asymmetry compared with the normal nostril. After dissection, repositioning of alar cartilage was done by same method in each case. A nasal stent was kept in position for at least 6 months postoperatively in almost all cases. After follow-up of 6 to 24 months, we concluded that our choice was correct in selecting the optimal operative method, considering the characteristics of deformity of the cleft side nostril in an effort to make it symmetric with that of the normal side.

Mucormycosis is an opportunistic fungal infection caused by the mucorales, which consist of the Rhizophus, Absidia, Mortierella, and Mucor. The diverse clinical forms of mucormycosis can be categorized as rhinocerebral, pulmonary, disseminated, gastrointestinal, cutaneous and miscellaneous. Although it can cause disease in healthy people, it most commonly affects patients who are diabetic or immunosup-pressed. Rarely, mucormycosis develops confined to the subcutaneous tissue. We experienced a case of cutaneous mucormycosis developed in a well-controlled diabetic patient who had previously injected foreign material on her face for an aesthetic purpose at the behest of an unlicensed physician. The patient had tissue necrosis and purulent discharge on her left cheek. Following histologic examination, we diagnosed the condition as cutaneous mucormycosis and treated it by wide excision combined with amphotericin B therapy. The disease was cured without any significant sequelae within 6 months of follow up. Cutaneous mucormycosis is rarely reported but it can cause facial deformity due to tissue necrosis, so that early diagnosis and appropriate treatment are important. Currently, foreign material injection for aesthetic purposes is still performed by unlicensed physicians. We present a case report concluding that one should consider the possibility of fungal infection in skin lesion in diabetic or other immunosup-pressed patients. We also emphasize the seriousness of illegal injection of foreign material.

Kainic acid[KA], a glutamic acid analogue, has been widely used as a excitotoxin in the study of neurotoxicity due to its ability to induce strong excitation and to increase intracellular calcium concentration of the mature central nervous system[CNS] neurons. However, it is not well known whether KA is also strongly cytotoxic to the neurons of the postnatal brain. We have injected KA into rats at different developmental stages and have investigated the changes in the expression of c-fos[transcriptional factor and a marker of neuronal activity], heat shock proetin 72[hsp 72, a neuronal injury marker], and glial fibrillary acidic protein[GFAP, a neuronal injury marker] mRNAs, which are known to be increased in KA-induced neurotoxicity, and glyceraldehyde 3-phosphate dehydrogenase [GAPDH, a house keeping gene] mRNAs with in situ hybridization histochemistry using specific riboprobes. The expression of c-fos mRNA was first identified in the CA3 area of hippocampus from 6hr after KA treatment in P7 rats. The c-fos mRNA-expressing area and the level of expression was gradually increased from P7 to adult. Hsp 72 mRNA was first expressed in the dentate gyrus and hippocampus from 6hr after KA treatment in P2l rats. In the adult rats, hsp 72 mRNA was broadly expressed in the brain at 2hr after KA treatment. The increase of GFAP mRNA expression was first identified in Pl4 rat brain from 6hrs after KA treatment, and by the development of brain it tends to appear earlier. The expression of GAPDH mRNA, however, did not show changes after KA treatment except for the adult rats showing a slight decrease at 12hr after KA treatment. These results suggest that KA may offer different level of cytotoxicity to the developing neurons by their developmental status and the difference may be correlated with the completion of synaptogenesis and increase of KA receptor.

PURPOSE: We evaluated the ability of endo-rectal coil MRI (ER-MRI) to predict the local pathological stage of prostate cancer prior to radical prostatectomy and compared the results with those of transrectal ultrasonography (TRUS). MATERIALS AND METHODS: ER-MRI using high field magnets (1.5 Tesla) were performed in 22 patients (mean age 62.8 years, range 51-73) with clinically localized prostate cancer before radical prostatectomy. Of the 22 patients, 17 patients were also assessed by TRUS. The results of the imaging techniques were compared with the post-operative histopathological findings. As one patient with pelvic lymph node metastasis, which was detected on frozen-section examination during surgery, was spared radical prostatectomy, the final evaluation included 21 patients. RESULTS: DSeven of the 21 patients (33%) were found to have extraprostatic extension (EPE), and 5 had seminal vesicle invasion (SVI). The sensitivity and specificity for diagnosing EPE using ER-MRI were 62.5% and 84.6%, respectively, and 16.7% and 100% with TRUS. The sensitivity and specificity for diagnosing SVI were 80.0% and 93.8%, respectively with ER-MRI, and 0% and 92.3% with TRUS. The accuracy of predicting SVI was 90.5% with ER-MRI compared to 70.6% with TRUS. CONCLUSIONS: ER-MRI was significantly better than TRUS for determining the local extent of prostatic cancer and for prediction of SVI in the preoperative staging of clinically localized prostate cancer.

The congenital long-QT syndrome (LQTS) is characterized by recurrent syncope, prolonged QT intervals, QT interval lability, polymorphic ventricular tachycardia, and sudden death. We report a case of congenital long QT syndrome in a 28-day-old male infant who presented with syncope, bradycardia with 2: 1 pseudo-atrioventricular block and a markedly prolonged QT inteval. One episode occured after crying and degenerated into ventricular fibrillation and terminated after cardioversion. A VVI type cardiac pacemaker was implanted. Subsequently, the infant's heart rate was over 110/min and 2: 1 AV block and any other arrhythmia were absent. The infant recovered from the accompanied pneumonia and sepsis and was discharged 47 days after adrnission. However, 13 days after discharge, the infant returned to our hospital ER with syncope. Ventricular fibrillation ceased after cardioversion. Despite medication with propranolol, ventricular tachycardia persisted. The infant expired the day after he was discharged against medical advice.
