Achilles tendon is the most powerful and the biggest tendon of the body and its rupture is frequently sports-related. Many authors reported the effects of mobilization, electricity, ultrasound and various drugs as factors influencing the injured tendon. We studied the effects of early passive mobilization after firm suture using plantaris tendon as tension suture material and reinforcing membrane on the repair of a ruptured Achilles tendon. From March 1992 to December 1995, twenty-two operations on the Achilles tendon were carried out in our hospital. 1. Fourteen patients were male and eight patients were female. The mean patient age was 38 years, ranging from 13 to 68 years. Average follow-up periods was 2 years and 7 months, ranging from 12 months to 3 years and 8 months. 2. The rupture site was 4.7cm proximal to the tendon insertion into the calcaneus on average. 3. We performed the operations with end to end suture technique. After approximation of the ruptured ends of the tendon with a No. 5 Ethibond tension suture using a modified Kessler stitch, placed plantaris tendon in a fascial needle and pass it circumferentially and distal plantaris tendon is fanned out and tacked over the repair. 4. Postoperative treatment was done as following protocol Short leg cast was done with equinus position for initial 3 weeks, and then cast was removed, hydrotherapy and passive exercises was employed. About 6 weeks after operation when the foot can be brought to right angle, a reverse 90degrees ankle stop short leg brace was applied for additional 6 weeks and partial weight bearing was aUowed. 5. Follow-up results were classified according to the Arner-Lindholm scale. We had 16 excellent results and 6 satisfactory results. After rigid suture it may be possible to introduce a regimen of progressive isometric stimulation and protected loading and streching combined with removable orthosis. Such early exercises are likely to improve the rate of rehabilitation over plaster immobilization.

Indirect composite resin are used as an popular effective esthetic material in prosthetic dentistry, often with metallic substructure that provides support for restorations. Recently, new indirect composite resins as a substitute of ceramic have been developed. These resins provide good esthetics, with a wide range of hue and chroma. And the flexural strength of those is in the range of 120-150MPa, which is higher than that of feldspathic ceramic, and similar tot hat of Dicor. Although it has many merits, one of the major clinical problems of composite resins is the bond failure between metal and resin due to insufficient interfacial bond strength. The purpose of this study was to evaluate shear bond strength of the reinforced indirect composite resin to dental alloys. Three different composite resin systems(Artglass . Sculpture , Targis ) as test groups and ceramic(VMK 68 ) as control group were bonded to Ni-Cr-Be alloy(Rexillium III ) and gold alloy(Dave 4). All specimens were stored at 37degrees C distilled water for 24 hours and the half of specimens were thermocycled 2000 times at temperature from 5degrees C to 60degrees C. The shear bond strengths of reinforced indirect composite resins to dental alloys were measured by using the universal testing machine, and modes of debonding were observed by stereoscope and scanning electron microscope. The results were as follows : 1. The shear bond strengths of reinforced indirect composit resins to dental alloys were approximately half those of ceramic to dental alloys(P<0.01). 2. There was no significant difference between the shear bond strength of several reinforced indirect composite resins to metal. 3. Alloy type did not affect on the shear bond strengths of resin to metal, but the shear bond strengths of ceramic to gold alloys were higher than those of ceramic to Ni-Cr alloys(P<0.05). 4. The shear bond strenghts of Artglass and Targis to gold alloys were significantly decreased after thermocycling treatment(P<0.01). 5. Sculpture showed cohesive, adhesive, and mixed failure modes, but Artglass and Targis showed adhesive or mixed failures. And ceramic showed cohesive and mixed failures.

BACKGROUND: Generalized aggressive periodontitis (GAP) is a destructive periodontal disease that can develop in young age. Only a few cases of full mouth rehabilitation, using dental implants, have been reported in a patient with aggressive periodontitis. CASE DESCRIPTION: This clinical report describes the treatment procedures and results of full mouth rehabilitation in a patient with aggressive periodontitis. After all teeth were extracted, 6 implants were placed in the maxilla and mandible, respectively. Fixed detachable implant prostheses were made. The patient was satisfied with the final results. She was followed for 10 months postloading. CLINICAL IMPLICATION: For a long-term success, continuous maintenance care is critical, as the contributing factors of the disease (such as immune factors or periodontal pathogens) may not be controlled adequately.

Teratomas are neoplasm composed of a wide variety of tissues foreign to the organs or anatomic sites in which they arise. They generally arise in gonads but a few cases are described in extragonadal sites, such as sacro-coccygeal region, mediastinum, neck, and retroperitoneum. Most sacrococcygeal teratomas are encountered in infants, particularly in neonates, and a primary sacrococcygeal teratoma is a extremely rare neoplasm in adults. Recently, we experienced two cases of presacral teratomas arising in adult, therefore we present these cases with a brief review of the literatures

Wilms' tumor is one of the most common primary malignant tumors of the kidney during infancy and childhood and is known to be originated from the primitive cells of metanephric blastema. It presents difficulties when encountered in deciding the presence of anaplasia or in differentiating it from other renal tumors of childhood with different biologic behavior because of its diverse histologic patterns and varying degrees of differentiation. Evaluation of clinical and histopathologic features in terms of prognostication was done of 32 cases of Wilms' tumor which were surgically resected and diagnosed in the period from January 1979 through June 1992. Immunohistochemical reaction for cytokeratin, vimentin, actin and desmin was also analysed on all cases of Wilms' tumor in conjunction with clear cell sarcoma of the kidney(CCSK), malignant rhabdoid tumor of the kidney(MRTK) and congenital mesoblastic nephroma(CMN) to assess the validity of immunohistochemistry in differentiating Wilms' tumor from these renal tumors. Twenty four(75%) cases were diagnosed before the age of 5 and 40.7% were under 2 years old. Mixed type was most common(62.5%), followed by epithelial, blastemal and stromal predominant type in descending order of frequency. Anaplasia was observed in 3 cases(9.4%), two of which were epithelial predominant type and one blastemal predominant type. Treatment modality and presence of anaplasia were significantly correlated with 5 year survival rate of patients. Immunohistochemical stain revealed that all epithelial component of Wilms' tumor were positive for cytokeratin and 56.3% of Wilms' tumor had blastemal component which were positive for both cytokeratin and vimentin. Twenty cases(62.5%) of Wilms' tumor had blastemal component which were positive for cytokeratin with a proportion of more than 5% of reactive cells. Stromal component of Wilms' tumor generally did not show differentiation into the specialized type of tissue and all revealed positive reactions for vimentin among which some revealed positive reactions for actin. Only 3 out of 6 cases with rhabdomyoblastic differentiation were positive for desmin. CCSK, MRTK and CMN which have different biologic behavior and treatment modality compared to Wilm's tumor showed positivity only for vimentin and/or actin. In summary, treatment modality and presence of anaplasia are significantly correlated with patients' survival and the immunohistochemical stain for cytokeratin is very helpful in confirming the presence of blastemal component and useful in the differential diagnosis of Wilms' tumor from other kinds of pediatric renal tumors.

Hypersensitivity myocarditis is an inflammatory disease of the myocardium usually related to drug allergy. The clinical manifestation may be nonspecific, and the diagnosis is seldom suspected or established during the life. So in most of the reported patients, the diagnosis was made at autopsy. Although, retrospectively, more than 90% of the patients described have had clinically recognizable cardiac involvement before death, tole clinical suspicion of hypersensitivity myocarditis is rare. The presence of nonspecific cardiac finding in a patient receiving any drug associated with hypersensitivity should alert the clinician to the possibility of drug related myocarditis. We experienced a case of hypersensitivity myocarditis accompanying allergic skin lesion in a 58 years old man with a history of taking cefadroxil. Fortunately, the outcome was favorable, therefore we do not have histologic confirmation of the diagnosis.
