Chronic anteromedial rotatory instability has not been demonstrated to have a satisfactory solution and we have experienced recurrence of the instability after operations. So the authors devised a new operative technique for the TCL (Tibial collateral ligament), that is, burying of the torn end of the ligament beneath the “ㄷ” shaped bony flap. It would better be called advancement and bony reinsertion operation. And we performed modifed MacIntosh tenodesis for the torn anterior cruciate ligament. The results were as follows: l. Of six knees, four (66.6%) rated “good”, two (33.3%) “fair”, and none (O%) “poor” (follow-up period; at least 6 months). 2. The technical problem of the advancement and bony reinsertion operation was discussed.

PURPOSE: To assess how accurately computed tomography (CY) can demonstrate the abnormal findings which are believed to cause the clinical signs and symptoms of hearing loss (HL), vertigo and facial paralysis (FP) in patients with temporal bone trauma. MATERIALS AND METHODS: The authors studied CT scans of 39 ears in 35 patients with temporal bone trauma. CT scans were performed with 1-115 mm slice thickness and table incrementation. Both axial and coronal scans were obtained in 32 patients and in three patients only axial scans were obtained. We analyzed CT with special reference to the structural abnormalities of the external auditory canal, middle ear cavity, bony labyrinth, and facial nerve canal, and correlated these findings with the actual clinical signs and symptoms. As to hearing loss, we evaluated 32 ears in which pure tone audiometry or brainstem evoked response audiometry had been performed. RESULTS: With respect to the specific types of HL, CT accurately showed the abnormalities in 84% (16/19) in conductive HL, 100% (2/2) in sensorineural HL, and 25% (2/8) for mixed HL. When we categorized HL simply as conductive and sensorineural, assuming that mixed be the result of combined conductive and sensorineural HL, CT demonstrated the abnormalities in 89% (24/27) for conductive HL and 50% (5/10) for sensorineural HL. Concerning vertigo and FP, CT demonstrated abonormalities in 67%(4/6), and 29% (4/14), respectively. CONCLUSION: Except for conductive HL, CT seems to have a variable degree of limitation for the demonstration of the structural abnormalities resulting sensorineural HL, vertigo or facial paralysis. It is imperative to correlate the CT findings with the signs and symptoms in those clinical settings.

Core tissue for histologic study is believed by many pathologists to be more diagnostic than material from needle aspiration. Recently introduced automated biopsy gun simplifies core biopsies with increased quantity and quality of samples. Authors performed 38 percutaneous biopsies from 38 patients with 18G automated biopsy guns under US guide. Diagnostic target tissues were obtained in 33 biopsies(87%), inadequate tissues in 4 (11%), and adequate but not of target tissue in 1(3%). There was no major complication requiring treatment, but pain needing analgesics and pain with nausea/vomiting were experienced in 2 and 1 biopsies respectively. Average number of needle passes was 1.5(1-5) We concluded that US-guided gun biopsy was a easy and safe way to obtained tissue samples of good quantity and quality, especially useful in hospitals without constant availability of specialists in cytopathology.

We present herein 3 cases of early secondary syphilis with simultaneous primary syphilitic lesions. These cases developed primary syphilitic lesions four to six weeks after sexual contact and lasted six to ten weeks thereafter until the secondary syphilitic lesions appeared. All three patients showed a strong positive for the STS. Spirochetes were seen under dark field examination of the primary syphilitic lesions, Histopathologically, numerous plasma cells around capillaries and endothelial hyperplasia were seen in the dermis.

PURPOSE: We investigated the possible inhibitory effect of aspirin during the initiation and post initiating stages on N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN) induced bladder carcinogenesis in female rats. MATERIALS AND METHODS: Forty-five female Sprague-Dawley rats were divided into three groups. Group A received 0.05% BBN in drinking water for 12 weeks. Group B re ceived 0.05% BBN in drinking water with 0.5% aspirin in the diet for 12 weeks. Group C received control diet without added chemicals. The rats were sacrificed after 12 weeks. For identification of chemopreventive effect of aspirin, apoptosis was detected by in situ cell death detection method. The apoptotic index (AI) was calculated from the ratio of typical apoptotic cells relative to the total cells from observation of at least 1000 cells in each preneoplastic lesion among the groups. RESULTS: All cases of group A showed multiple lesions of simple and focal hyperplasia. The incidence of papilloma was 80% in group A. All cases of group B also showed multiple lesions of simple and focal hyperplasia but the incidence of papilloma was decreased to 20%. The total numbers counted of focal hyperplasia and papilloma lesions were significantly reduced in group B than in group A (p<0.001 and p<0.001, respectively). The mean AI in group A and B sequentially increased in preneoplastic lesions, as compared to that in the normal epithelium of the rat bladder. Significant differences in AI in the lesions of simple and focal hyperplasia between group A and B were noted (p<0.001 and p<0.001, respectively). CONCLUSIONS: The result suggests that aspirin significantly decreases the incidence of precancerous lesions and it can act as a chemopreventive agent for precancerous lesions of urinary bladder.

BACKGROUND: Hydrofluoric acid(HF) is one of the strong stirritating, corrosive and poisonous inorganic acid, The HF burns are occuring with ever-increa firifrequency due to the wide use of this acid in industrial fields, such as electronics and semicor tor industries. OBJECTIVE: The purpie of this study is to quantiate theound depths produced by varying concentrations of HF aiud to suggest the treatment guideline. METHODS: Uarious cinicentrations of HF(5%, 25%, 50%),were applied to two pairs of test sites on a guinea pig's back in a uniform fashion with cotton-tip applicators and then the histopathologic changes of guinea pig skin were observed. RESULTS: 1, In the 5% HF applied group, intracellular edema vaobserved in the epidermis after 12 hours. After 3days, epidermal cell necrosis was observed. 2. In the 25% HF applied group, intraepidermal vesice was observed after 6hours. After 12hours, inflammatory cell infiltrations were observed in the apper dermis and then after 3days, dermal necrosis was oberved. 3. In the 50% HF applied group, epidermal cell necros After 6hours, liquefaction degeneration in the epidermis an was observed focally after 3hours. iflhmmatory cell infiltrations in the upper dermis were observed. After 2days, dermalar.ecrosis was observed and then after days, the reaction was at its peak and subcutaneous tissuc. necrosis was observed. CONCLUSION: This study showed that a higher concentrator HF exposure enhances The penetration of HF. For treatmi not alcohloic solution of a quarternary ammonium for avintralesional injection of calcium gluconate within 24 hours of HF and a longer period after we suggest wet dressing with an concentration of HF burn and high concentration of HF burn.
