Modified Mohs surgery is a procedure which eliminated chemical fixation step from Mohs chemosurgery. This technique is faster, less painful and more tissue conserving, allows for immediste repairs, yields higher quality histologic preparations and facilitates an interdisciplinary apporoach; it is the treatment of choice for recurrent or difficult skin cancers. A 58-year-old femele patient presented with a 2x 3cm sized dark brownish, ulcerated nodule on the left upper eyelid. Histopathologic findings revealed several small solid nest composed of basalioma cells in the dermis. We treated with modified Mohs surgery and obtained good result.

We report a case of trichorrhexis nodosa in a 27-year-old male. Scanning electron microscopic findings reveals those of typical trichorrhexis nodosa nodal swelling of affected hair showed longitudinal fissures and fractures in the cortex. A paintbrush effect was noted at the site of fracture. Simple avoidance of trauma gave some regrowth of hairs.

Chondromalacia patella is a symptom complex characterized by aching pain behind the knee cap, retropatella tenderness that is aggravated by the stair climbing. Malalignment is an important factor causing chondromalacia patella. And to recognize it, is important in the diagnosis and treatment. We studied 3 parameters in the chondromalacic knee and nonchondromalacic knee and the following results was obtained. l. In nonchondromalacic knee, the sulcus angle is 141° 7′ and the congruence angle is −5° 1′ 2. In chonduomalacic knee the sulcus sagle is 139° 2′ and the congruence angle is +5° 3′ 3. In the group with abnormal congruence angle, there was much degenerative changes in the patellofemaral joint. So, it can be inferred that chondromalacia is a precursor of the osteoarthritis and the patient with abnormal congruence angle should be treated actively at the early stage if the conservative treatment had failed.

The purpose of this study was to determine the proliferative activity of the osteoblasts and fibroblasts in the midpalatal area and to investigate the adjacent periodontal tissues of individual tooth following rapid expansion of the palate. Ten young adult dogs, aged approximately ten months, were used in the experiment. The experimental design was consisted of 1 week expansion group(Group E1, 3 dogs), 2 week expansion group(Group E2, 3 dogs), 2 week expansion and 2 week retention group(Group E3, dogs), and control group(Group C, 1 dog). For each group, expansion screw was activated one time per day(1/4 turn;90degrees) following Hyrax-screw application. The experimental animals in each group were sacrificed at 1, 2 and 4 weeks following palatal expansion. Maxillary tissue blocks wee obtained and prepared for the histomorphologic and immunohistochemical studies. Light microscope, polarizing microscope, and soft X-ray apparatus were used in this study, and following results were obtained. 1. In polarizing microscopic study, the expansion group(E1 & E2) showed blue color representing bone resorption and new bone formation in midpalatal suture area. E3 groups showed less color compared to the E1 and E2 group. But yellow color increased by calcification in the E3 groups. 2. Immunohistochemical study revealed that positive responses of the osteoblasts to PCNA and undifferentiated fibroblasts to EGF in E1 group were somewhat increased. Positive response to PCNA and EFG were increased in fibroblasts and the osteoblasts forming new bone in E2 group. In E3 group, the positive response cell concentrated the periphery of edge of palatal process in both PCNA and EGF. 3. Throughout the expansion period(E1 & E2), light microscopic study showed the edges of the extensive resorption new palatal processes, indication bone remodeling within the suture. E3 group exhibited less remodeling of midpalatal suture area. E2 group and E3 group showed cementum formation and resorption at the apex of 3rd premolar and 1st molar. E3 group exhibited extensive hyalinized zone on the cervical portion of buccal side of 1st molar. 4. Soft X-ray analysis of E1 group showed hypomineralized defect and microfractures in various parts of the suture areas when compared with control animals. There was no significant difference in the degree of mineralization in the midpalatal suture region between the C and E3 groups. Tooth axis showed tipping of 3rd premolar and 1st molar in the E2 group and E3 group. Based upon these experimental results, it is concluded that the undifferentiated mesenchymal cells always presented in midpalateal suture area following RPE. Differentiated osteoblasts and fibroblasts possess proliferating cellular activity until the 2 week retention period. The posterior teeth area tend to tip buccally as RPE force applied. Retention group exhibited irreversible response with severe hyalinized on the buccal surface of the first molar.

Human Papillomaviruses(HPVs) are regarded as sexually transmitable and closely associated with precancerous lesions or invasive cancers of the vulva, vagina, and cer V1X. In situ hybridization, besides showing higher sensitivity, allowed the identification of specific viral types. We studied 12 cases of condylomata accuminata for HPV typing by in situ hybridization techenique. Ten cases(83.3 % ) showed positive for HPV type 6/11, and 2 cases(16.7% ) were positive for HPV type 16/18.

BACKGROUND: Hemoptysis is a common clinical symptom responsible for 11% of admission to the hospital chest service. In KOREA pulmonary tuberculosis is still the most common cause of hemoptysis and the incidence of hemoptysis due to neoplasia has increased. Bronchoscopy and high resonance CT are essential for diagnosis of the cause of hemoptysis. We studied the causes, diagnostic tools and treatment treatment of hemoptysis. METHODS: We conducted a retrospective analysis of clinical profiles, radiologic and bronchoscopy findings and treatments of hemoptysis for 220 patients who were admitted to our hospital with hemoptysis between 1994 and 1998. RESULTS: The mean age at diagnosis was 49.3 years and male to female ratio was 2.1:1. The main causes were active pulmonay pulmonary tuberculosis in 72 cases(32.7%), inactive pulmonary tuberculosis with sequlae in 69 cases(31.4%) lung cancer in 43 cases(19.5%), bronchiectasis in 10 cases(4.5%), and chronicbronchitis in 10 cases(4.5%). The mean amount of hemoptysis for 24hrs was 120cc. The mean duration of bleeding was 25 days. The number of cases with a past history of pulmonary tuberculosis were 128 cases, in which 24 were relapsed tuberculosis cases, 25 chronic tuberculosis cases, 69 inactive tuberculosis cases, and 10 lung cancer cases. High resonance CT was the most useful method for structural etiologic evaluation of hemoptysis developed in patients with inactive tuberculosis, bronchiectasis and aspergilloma. sputum study and bronchofiberscopy were the confirmative diagnostic tools for active pulmonary tuberculosis and lung cancer. The treatments of hemoptysis medical in 152 cases(71.7%), bronchial artery embolization in 39 cases(17.8%), and operation in 9 cases(4.0%). The mean following up duration was 22.4 months. The overall outcomes of hemoptysis were controlled in 77 cases (43.5%), rebleeding in 100 cases (56.5%) and expired in 9 cases (4.0%). The outcomes of hemoptysis in pulmonary tuberculosis were controlled in 21.6%, rebleeding in 78.4%, and expire in 14.7%. CONCLUSION: The most common cause of hemoptysis was related with pulmonary tuberculosis. HRCT was an important diagnostic tool in AFB smear negative active pulmonary tuberculosis and inactive tuberculosis with sequelae. Early, proper management of pulmonary tuberculosis is important for prevention of hemoptysis in Korea.
