The elbow joint is the most commonly dislocated-joint in the body except for the shoulder, and in children less then 10 years old, it is the most frequently dislocated articulation. The injury and the treatment are well described in most standard textbooks, but the characteristic findings and follow-up evaluations are not generally recognized. Authors have clinically analyzed 45 cases of traumatic fracture and dislocation of the elbow joint which are treated between January, 1975 and June, 1985 at the Department of Orthopedic Surgery, Wonju Medical College of Yonsei University. The results were as follows; 1. The age incidences were in even distribution except in the old ages where the incidence was low and the male to female ratio was 7: 3. 2. The major cause of the injury of the elbow was fall down (60%). 3. Posterior and posterolateral dislocations were about 60% of all cases. 4. Associated fractures were 35.6% of all the elbow dislocations, of which medial epicondyle fracture had the highest incidence. 5. Complications including ulnar nerve injury (3 cases), median nerve injury(1 case), radial nerve mjury(1 case), rupture of brachial artery(2 cases), recurrent dislocation(1 case) and calcification of ligament(2 cases) were observed. 6. Pure elbow dislocation occurred in 13 cases (28.9%). 7. The average immobilization period for patient with non-operative treatment (45%) and operative treatment(55%) were 7 days and 3 weeks, respectively, and much better results were seen in patients with non-operative treatment than in operative treatment and in shortened immobilization period.

A case of severe osteoarthritic patient of both hip treated with McKee-Farrar total endoprosthesis on one hip is reported. The introduction, indication, procedure of the surgery and the use of the self curing acrylic cement were reviewed briefly. The hip following the surgery, even though the follow-up duration is short, showed exceIlent result.

It is well-known that the infection of bone and joints could produce the shortening by destroying the articuiar cartilage and growth plate, or the lengthening hy increased hlood circulation to the epiphyseal and metaphyseal regions of long bone. Since 1985, we have treated total l7 cases of children s pyogenic or tuberculous children s knee with early arthrotomy and continuous irrigation etc. and followed their long hone growth for average 53 months after surgical intervention. Five patients (group I ) were early treated within 2 weeks and twelve patients(group 3 ) were delayed to treat their knees for more than 2 weeks of symptom development. Total 11 patients out of 17 cases(64.7%) (2 cases of group 1 pyogenic arthritis, and 1 case of group l and 8 cases of group II tuberculous arthritis) revealed growth acceleration. Femoral lengthening was much more greater than that of tibial growth, and the size of patella, distal femoral and proximal tibial epiphysis which were measured by computerized digitizer were also significantly larger than that of opposite knee. The total limb length was increased hy average 7mm in 6 months, l4mm in 1 year and 3mm in 2 years after operation. These results suggest the pyogenic and tuberculous arthritis in children s knee should he treated as early as possible after symptoms developed, and followed them to trace their limh inequality for at least 2 years after surgery. That means the early arthrotomy for tuberculous knee or even in pyogenic arthritis can preserve normal articular cartilage and can also prevent the early epiphyseal closure hy infection. and can get the limh lengthening by increased blood circulation around the knee joint.

OBJECTIVES: Auditory verbal hallucination (AVH) is knoun for its high prevalence and difficulty in evaluation. Authors hypothesized that it may be possible to find useful dimensions of AVH that reflect the clinical status of schizophrenic patients by assessing the multi-dimensional changes and linguistic forms' of AVH during antipsychotic treatment. METHODS: 33 schizophrenic patients with AVH were selected and periodically assessed with the 11 items of hallucinations subscale of 'The Psychotic Symptom Rating Scales (PSYRATS)'. In addition, to assess the linguistic forms observed in the AVH, the evaluations of sentence structure of AVH reported by the patients were conducted. RESULTS: PSYRATS showed the multidimensionality inherent in AVH. The changes in the quantitative dimensions did not correlate well with patients' subjective distress. However, qualitative changes in the cognitive and emotional dimensions showed more favorable correlation with clinical course of the patient. The sentence structures of AVH showed tendency to change from "sentence" to "non-sentence" type with overall improvement during treatment. CONCLUSION: Multi-dimensional approach to AVH can give us more information about the changing patterns of multi-faceted structure of AVH and clinical status of patients than one-dimensional or categorical approach.

Verrucous carcinoma is a slow growing, low grade squamous cell carcinoma, which usually occurs on oropharynx, genitalia and soles. When it occurs on feet, it is known as epithelioma cuniculatum. Epithelioma cuniculatum is characterized by its histologic sinuses and cystic formations in a cuniculate(rabbit burrow-like) pattern. A 59-year-old man was consulted to our department for a well circumscribed, 5 × 5 cm sized, round, hyperkeratotic, verrucous plaque on the right great toe. He suffered from diabetes mellitus for 16 years and was managed by peritoneal dialysis three times a week due to chronic renal failure for last two years. The plaque had gradually increased in size. The biopsy specimen taken from the tumor mass showed chronic ulcerative inflammation with atypical squamous cell proliferation. We herein report a case of verrucous carcinoma occurring in a patient with diabetes melli-t tus and chronic renal failure.

Bond strength of luting cements to dentin is a critical consideration for success of complete cast crowns. This study was performed to evaluate the relationship between surface characteristics of teeth prepared for complete cast crowns and retention of cemented restorations. Eighty artificial crowns were cast for standardized complete crown tooth preparations accomplished with the use of a special device on recently extracted human teeth. Coarse diamond(#102R, Shofu) and superfine finishing diamond(#SF102R, Shofu) burs of similar shape were used. Crowns in each group were randomly subdivided into four subgroups of 10 for luting cements selected for this study: zinc phosphate cement (FLECK'S), polycarboxylate cement (Poly-F), reinforced glass ionomer cement (Fuji PLUS), and adhesive resin cement (Panavia 21). Retention was evaluated by measuring the tensile load required to dislodge the artificial crown from tooth preparations with an Instron testing machine, and analysed by one-way ANOVA and Student's t-test. The obtained results were as follows ; 1. When tooth preparation was done with coarse diamond bur, retentive force was diminished in order of Panavia 21, Fuji PLUS, FLECK'S, and Poly-F. Retentive forces showed the significant difference between Fuji PLUS group and FLECK'S group(p<0.001). 2. When tooth preparation was done with superfine diamond bur, retentive force was diminished in order of Fuji PLUS, Panavia 21, FLECK'S and Poly-F. Retentive forces showed the significant difference between Panavia 21 group and FLECK'S group(p<0.001). 3. Retentive force in coarse tooth surfaces was significantly higher than that in superfine tooth surface with all luting cements(p<0.001), and cement residues were almost retained with in the cast crown in all groups.
