The metal ceramic crown is currently the most popular complete veneer restoration in dentistry, but in many cases, the metal cervical collar at the facial margin is unesthetic and unacceptable. Facial porcelain margin has been used in place of it. But this dose not solve the problems, such as dark gingival discoloration and cervical opaque reflection of porcelain veneer. Recently, metal copings which were designed to terminate its labio-cervical end on the axial walls coronal to the shoulder have been clinically used to solve the esthetic problem of metal ceramic crown. But in this design, porcelain veneer of labio-cervical area which is not supported by metal may not be able to resist the stress during cementation and mastication. The purpose of this study was to evaluate fracture strength and fractured appearance of crowns according to different coping designs. A resin maxillary left central incisor analogue was prepared for a metal ceramic crown, and metal dies were made with duplication mold. Metal copings were made and assigned to one of four groups based on facial framework designs: group 1, coping with 0.5mm metal collar; group 2, metal extended to the shoulder; group 3, metal extended to 1 mm coronal to the shoulder; group 4, metal extended to 2mm coronal to the shoulder. Copings and crowns were adjusted to be same size and thickness, and cemented to metal dies with zinc phosphate cement by finger pressure. Fracture strength was measured with Instron Universal Testing Machine. Metaldies were anchored in Three-way-vice at 3mm below finish line and at 130degree inclined to the lone axis of the crown. Load was directed lingually at 2mm below midincisal edge. Load value at initial crack and at catastrophic fracture was recorded. The results obtained were as follows: 1. Fracture strength values at initial crack were higher in groups 1, 2 than in groups 3, 4 but this difference was not statistically significant(P<0.05). 2. Conventional metal collared crown had greater catastrophic fracture strength than any other collarless crowns. 3. The greater the labial metal coping reduction, the lower the catastrophic fracture strength of crowns but when more than 1mm of labial metal reduction was done, the difference in strengths was not statistically significant(p<0.05). 4. The strongest collarless coping design was group 2.

Cutaneous metastatic tumors on the scalp from the rectum are very A 66-year-old male presented a nodule and papule an his scalp three months after surgical removal of a rectal adenocarcinorna. Biopsy specien from the scalp showed adenocarcinoma which is similar to the primary rectal carcinoma.

Fungal infection has been observed with increasing frequency in recent years because the use of combinations of broad spectrum antibiotics, immunosuppressive agents, and antineoplastic agents is increasing and the survival rate of premature baby is increasing. We experienced a 3 month old male infant with anuria due to bilateral ureteropelvic fungus balls. He was born at 31 weeks gestation period and had been treated with broad spectrum antibiotics for 5 weeks after birth. We removed fungus balls surgically and made nephrostomy bilaterally. And then irrigation of amphotericn B through nephrostomy and systemic amphotercin B injection had performed for 3 weeks. Thereafter fungus balls completely disappeared.

The paratertiary butylphenol formaldehyde resin(PTBP-FR) is commonly used in neoprene shoe adhesive to provide stability, durability, flexibility, and to stick quickly. We report here a case of allergic contact dermatitis in a 22-year-old female, who had well defined, pruritic, erythematous, and papulovesicular lesions on the lateral side of the left foot and ankle for 3 years. Patch test showed 2+(vesicular) reaction .to PTBP-FR(1% in petrolatum), a piece of leather shoes(as is), and a piece of leather watch strap(as is).

Type II mucopolysaccharidosis (MPS II) commonly known as Hunter syndrome, is a rare X-linked lysosomal storage disorder caused by iduronate-2-sulfatase deficiency, which in turn causes otorhinolaryngological manifestations, including sensorineural hearing loss (SNHL). Previously, the median survival age of patients with MPS was approximately 13.4 years. However, in the era of enzyme replacement therapy and other multidisciplinary care modalities, the life expectancy has increased. Herein, we report a rare case of an adolescent with MPS II who underwent SNHL treatment with cochlear implantation (CI). Based on unexpected findings of mastoid emissary veins and overgrowth of the vessels around the temporal bone, CI was performed using the transmeatal approach instead of the conventional transmastoid method, to avoid damage to the vessels. The average hearing threshold after CI was 35 dB and no surgical complications were encountered. Adolescent MPS II may present vessel abnormalities, which can reduce the success rate of surgery. In patients with MPS II with SNHL, CI should be performed under careful monitoring of vessel overgrowth. Moreover, with regard to feasibility of CI in adolescent patients with MPS II with SNHL, surgical techniques such as the transmeatal approach should be selected based on adequate assessment of the case.
