BACKGROUND: Even though excellent impression materials are now available for making accurate replication for hard and soft tissue, the numerous dentists have faced lots of obstacles in making simultaneous impressions of multiple abutments. CASE DESCRIPTION: This article describes a modified method of tray fabrication using auto-polymerizing acrylic resin and impression technique for multiple prepared teeth in cases with limitations and difficulties in taking dental impressions. CLINICAL IMPLICATION: This segmental tray technique has several advantages, including higher impression quality, fewer impressions, and being more comfortable for the patient and less stressful for the clinician.

Two cases of vertebra plana due to eosinophilic granuloma were experienced and successfully treated by anterior fusion of the involved spines at the department of Orthopedic Surgery in Seoul National University Hospital. Literature on the subject was reviewed.

The prognostic significance of vascular (blood and lymphatic vessels) invasion was evaluated in a retrospective review of 27 patients with upper urinary tract transitional cell carcinoma from January 1985 to December 1993, who underwent a nephroureterectomy with bladder cuff resection. Vascular invasion was found in 10 patients (37%). The incidence of vascular invasion was well correlated with tumor grade and stage. The incidence of postoperative metastases was significantly higher in the patients with (70%) than without (17.6%) vascular invasion (p<0.05). The survival rate of the patients with vascular invasion was significantly lower than in those without vascular invasion (p<0.01). In multivariate Cox`s regressional analysis the prognostic value of vascular invasion was independent of tumor grade and stage. These results indicate that vascular invasion should predict a more unfavorable outcome in patients with upper urinary tract transitional cell carcinoma as an independent morphological indicator.

Albinism is an inherited ongenital disarder in which there is sgr neralized decrease or absence of pigrnent in the eyes, skin, and hair. There are two general groups (1) Oculocutneou albinism, (2) Ocular albinism. Skin cancers in albinos are rare in ternperate clirnats and t.hey occur rnostly on sun ex posed areas. We present a case of recurrance of squarnous cell carcinoma ir a Korean albinoid on both sides of the neck and right ear. On liistopathologic examination, we find I or pearls, and irregular mases of epidermal cells that proliferite downward into the devmis. The invaing cell masses are composed of atypical squamous cells.

After the analysis of 40 pediatric patients who underwent exploratory surgery under the diagnostic impression of testicular torsion for the period of 8 years from January 1981 to December 1988 in terms of age distribution, clinical features, diagnostic methods, therapeutic options, outcome and follow up, the results can be summarized as follows : 1. The most common causes of the disorder were testicular torsion (50% ), and torsion of append ages (33%). The remaining 17% of the cases were acute epididymitis (13%), orchids (2%), and hydrocele (2%). The prevalent ages for testicular torsion was over 11 years old (80%). On the other hand, torsion of appendages mainly affected children below 11 years old. 2. The observation of the presence or absence of the cremasteric reflex helped to differentiate the diagnosis of acute scrotum. Testicular scanning in 2 cases with vague symptoms provided to determine testicular torsion. With the endoscopic evaluation of the inside of tunica vaginalis, which was the first trial in these cases, we diagnosed 2 cases of testicular torsion. 3. Among the 20 patients with testicular torsion, 7 required orchiectomy because of obvious necrosis. There were 13 testes considered to be salvageable and they were fixed successfully. The early salvage rate of surgery in testicular torsion was 100% (9/9) for the patients operated less than 24 hours after torsion, and 36% (4/11) for the patients over 24 hours. The overall immediate testicular salvage rate was 65% (13/20). 4. Semen analyses revealed normal for 2 patients who underwent orchiectomy for testicular torsion that had lasted over 48 hours. Testicular scans 2 weeks after fixation in 2 patients with testicular torsion that had lasted 12 and 16 hours, showed normal perfusion. In conclusion, immediate scrotal exploration followed by appropriate treatment would result to maximal testicular salvage, minor morbidity and rapid symptomatic improvement in patients with pediatric acute scrotum.

Although more reports on the fungal keratitis are recently coming out, cases of mixed infection by two or more fungal agents have not yet beenreported in the literature. The authors experienced a case of fungal keratitis caused by a combination of Fusarium solani and Acremonium falciforme in which central corneal ulcer with severe suppurative infilteration and hypopyon were observed. Since the conditions were resistant to conservative treatment and corneal perforation occurred despite of medical treatment, penetrating keratoplasty was performed along with postoperative topical and systemic antifungal therapies for several weeks and good results were obtained with no evidence of recurrence.

Hamartoma of the breast is a rare benign lesion presenting as palpable mass. They are, however, sometimes misdiagnosed by pathologist due to their resemblance to other benign or physiologic conditions of the breast. We report two cases of hamartomas of the breast. The clinical diagnosis was fibroadenoma in both cases. One patient was a 49-year-old woman presented with palpable mass for the duration of 5 months. Mammography showed a well demarcated round mass with homogeneous density which is slightly greater than the surrounding glandular tissue. Grossly it was a 3.5 3.0 2.0 cm sized round firm mass covered by thin fibrous tissue. Microscopically it was a well defined mass composed of variable amount of breast lobules, dilated ducts and adipose tissue surrounded by dense hyalinized connective tissue. The adipose tissue accounted for 30% of the entire lesion. Cellular atypism was not found. The other patient was a 18-year-old woman presented with palpable mass of the duration of 3 years, which was increased in size recently. Mammography demonstratesd a well delimited lobulated mass with lucent halo. Ultrasonography showed a well encapsulated low echoic mass admixed with high echoic areas. Grossly, it was a 4.0 4.0 2.0 cm sized well demarcated oval-shaped firm mass with translucent thin fibrous capsule.. Microscopic findings were similar to the former. The amount of adipose tissue was 20%.

A case of linear IgA bullous dermatosis reported. A 32-year-old male with pruritic, papulovesicular eruptions on the whole body of 2 months' duration was examined. He had no history of diarrhea or fou]smellirig stool even though his diet cnntained gluten. A skin biopsy revealed subepidennal vesicles and papillary microabscesses infiltrated by many neutrophils and some eosinophils. Direct irnmunofluorescent examination of the perilesional skin showed a linear deposition of IgA along the basement mernbrane zone. The lesions responded rapidly to oral dapsone and topical steroid therapy but recurred whenever the oral mcdication was discontinued.
