The palatal fracture results in deformity of the midface, as well as change in occlusion. However, no report was found on the incidence, treatment and results of palatal fracture in Korea. A retrospective review was done over 6 years and 11 patients(6.5%) with palatal fracture were determind out of 168 patients who had midfacial bone fractures without nasal bone fracture. According to the Hendrickson's classification, the number of patients with specific types of palatal fracture was described as follows; sagittal (2 cases), parasagittal (2 cases), para-alveolar (3 cases), transverse(3 cases) and complex(1 case). Le Fort I (6 cases), Le Fort II (7 cases) and mandible (6 cases) fractures were also associated. Open reduction and internal fixation was applied to all patients. Internal fixation consisted of pyriform or alveolar ridge stabilization and maxillary buttress stabilization. The rigid palatal vault stabilization was applied in one patient with midline split of the palate. The duration of intermaxillary fixation was shortened to less than 3 weeks from 4 to 6 weeks with rigid fixation. The palatal splint was used temporarily before internal fixation. All the patients showed good bony union and satisfactoryocclusion postoperatively. Open reduction and internal fixation showed satisfactory results from the aspects of stability, occlusion, patient convenience and final aesthetics. The following treatment model for palatal fracture according to the fracture type is proposed; 1) Alveolar type - close reduction or open reduction and selective alveolar ridge fixation and selective application of palatal splint, 2) Sagittal type - open reduction and internal fixation of the alveolar ridge, maxillary buttress and palatal vault. 3) Parasagittal type - open reduction and internal fixation of the pyriform aperture and maxillary buttress, as well as selective fixation of the palatal vault. 4) Para-alveolar type - open reduction and internal fixation of the alveolar ridge and maxillary buttress. 5) Complex type - open reduction and internal fixation of the alveolar ridge, maxillary buttress, pyriform aperture and continuous use of a palatal splint to bony union. 6) Transverse type - open reduction and internal fixation of the alveolar ridge and maxillary buttress.

To find clinical significance of routine “dipstick” urinalysis on admission, we analyzed the results of the “dipstick” urinalyses performed in 844 patients admitted to the pediatric department of Yeungnam University hospital from May 1, 1983 to October 31, 1984. Ketonuria, proteinuria, hematuria and glucosuria were found in 9.5%, 4.9%, 2.4% and 1.1% of the patients respectively. There were no significant differences by sex, age and presence of fever. However, proteinuria and ketonuria were found more frequently in the patients with dehydration (p<0.05). All of the patients with proteinuria and ketonuria showed negative results on follow up. However, among 13 patients with hematura, 9 patients showed negative results and 4 patients had persistent hematuria on follow up. These 4 patients were found to have chronic pyelonephritis (2), asymptomatic urinary tract infection (1) and benign recurrent hematuria (1). This routine “dipstick” urinalysis on admission seems to be simple test which is useful in detecting unrecognized kidney and other urinary tract disease.

It has been clarified that myoepithelial cells contain S-100 protein which is known to be a marker protein of neural tissue. To evaluate the participation of myoepithelial cells in the histogenesis of the salivary gland tumors, normal salivary glands and various salivary gland tumors were stained by immuno-peroxidase method. PAP kits (DAKO Co, USA) for the S-100 protein and the Cytokeratin were used and the following resulting were obtained. Acinic cells of the normal salivery gland were negative for both cytokeratin and S-100 protein. The intercalated duct cells were weakly positive for cytokeratin and S-100 protein. The normal myoepithelial cells scattered around the acini and the intercalated ducts were positive only S-100 protein. In contrast, the striated duct were positive only for cytokeratin. In plemorphic adenoma, the S-100 protein positive cells were found in solid sheets of tumor cells, in chondromyxoid areas and in areas of spindle-cell stroma as well as in the outer layer of the tubular structures. Only the inner lining of the tubules were positive for cytokeratin. In basal cell adenoma, the stromal spindle cells were strongly positive for S-100 protein and the epithelial cells weakly positive. When tubules were present within the epithelial sheets, the inner most lining cells were positive for cytokeratin. The peripheral palisaded tumor cells were negative for both substances. By immunostaining of the adenoid cystic carcinoma, S-100 protein containing cells were found focally scattered independently on the variety of histologies. The lining cells of true cystic structure were positive for cytokeratin. Immunostaining of the mucoepidermoid carcinoma demostrated that the squamous cells and the tubular epithelial cells contained cytokeraitn, whereas only a few intermediate cells were positive for S-100 protein. In Warthin's tumor there were no S-100 protein positive cells, although basally located epithelial cells of the papillae were positive for cytokeratin. These findings suggest that salivary gland tumors other than the Warthin's tumor arise from myoepithelial cells or reserve cells having dual potentiality differentating into myoepithelial and intercalcated duct cells.

A 26-year-old man presented with a bluish speckled patch on the dorsum of the left hand. It had apperaed at birth as a bluish spot. Since adolescence the lesion extended and at the time of visiting hospital it covered the most part of the dorsum of the left hand and even some palmar aspect. The histopathological and ultrastructural examination revealed numerous dermal melanocytes, mainly in the upper dermis. Clinically and pathologically, the patient was diagnosed as having dermal melanocyte hamartoma, a distinct type of dermal melanocytosis.

PURPOSE: Pilomatrixoma is a benign, usually asymptomatic tumor. It presents clinically as a solitary superficial subcutaneous nodule measuring between 0.5 cm and 5 cm in diameter on the head or upper extremeties and has not been reported after skin graft. The objective of this article is to report our experience in treating pilomatrixoma which occurred after split thickness skin graft on the lower extremity. METHODS: A 56-year-old female was treated in August 2005 with a 0.5 X 0.5 cm firm subcutaneous nodule at recipient site of split thickness skin graft on the left medial thigh. The tumor was successfully removed by complete excision and histologic examination was followed. RESULTS: The diagnosis was pilomatrixoma which was characterized by a dual population of proliferating basophilic cells and diagnostic shadow cells. CONCLUSION: The tumor was successfully treated by complete resection. The authors report this very rare case of pilomatrixoma which occurred at recipient site of split thickness skin graft.

PURPOSE: To evaluate the frequently of low ahetenuation area in enhanced CT scans of non-Hodgkin lymphoma(NHL) and to find out if there is any pertinent relationship between this and the histopathologic classification. MATERIALS & METHODS: The authors reviewed CT scans in the newly diagnosed 53 patients with NHL. We defined the-low attenuation area as the one with CT attenuation value lower than that of the muscle, surrounding lesion, or other lymph nodes after contrast enhancement. NHL with the low attenuation areas were correlated with the histopathologic findings according to the classification based on the Working Formulation and the frequency of the lesion was evaluated. RESULT: Of the 53 patients, the low attenuation area was found in 13 patients (25%) at CT. The histopathologic classification could be made in 12 patients, among whom one patient was classified as low grade, six as intermediate grade, and five as high-grade. Concerning the specific cell typing, the diffuse large cell type was most common in intermediate-grade NHL seen in five patients and the large cell, immunoblastic type was most common in high-grade NHL seen ih three patients. CONCLUSION: The authors concluded that the low attenution area within lymphoma is not an infrequent finding at CT, and there was no stastistically significant correlation between this finding and the prognostic grading of the Working Formulation.

We present three cases of eosinophilic pustular folliculitis without eosinophilia in a 19-year-old female, a 27-year-old male, and a 51-year-old male. Multiple erythematous plaques with papules and pustules were observed on the face in two patients and on the face, trunk, and extremities in the third patient. Histopathologic findings showed hair follicles and the sebaceous glands infiltrated with mixed inflammatory cells composed of eosinophils and neutrophils, characteristic of eosinophilic pustular follicultitis. However, peripheral blood eosinophilia was not present in any of our three cases.
