Retrospective study about the postoperative stability of zygomaticomaxillary complex fracture / 대한악안면성형재건외과학회지

Background@#The aim of this study is to evaluate the postoperative stability of zygomaticomaxillary complex (ZMC) fractures according to the number of fixation sites and to investigate the direction of postoperative displacement of the unfixed part of the fractured segment. @*Methods@#This study was retrospectively performed on 38 patients who were treated by open reduction and internal fixation of ZMC fractures and were taken postoperative computed tomography (CT) between February 2012 and July 2019. The patients were classified into 3 groups: 1-point fixation, 2-point fixation, 3-point fixation according to the number of fixations. The postoperative displacement of the fractured segment was evaluated by the superimposition between postoperative CT and follow-up CT, and the postoperative stability according to the fixation sites was investigated through the amount of postoperative displacement. In addition, it was investigated in which direction the location of the fractured segment was changed in the unfixed fractured segment according to the fixation sites. @*Results@#The amount of postoperative displacement of the fractured segment was 0.75 ± 1.18 mm on average. In the postoperative displacement of the distal area according to the number of fixation of the fracture, there was no statistically significant difference in the amount of displacement of the fracture (p = 0.574). As for the direction of the change in the location of the fractured segment, 12 patients among 38 patients with the change in the location of the fractured segment were investigated, and the displacement in the medial direction (n = 11, 91.67%) was the most common in all three fixation methods. @*Conclusion@#In patients with a ZMC fracture who were treated by open reduction and internal fixation, the number of fixations did not make the difference in the postoperative displacement of the fracture. In addition, the fractured segment mainly changes in the medial direction after surgery, and this fact can be used as a reference for the reduction direction during surgery for the stable prognosis.

Chronic Dermatophyte Infection Recalcitrant to Various Antifungal Agents Therapy / 대한의진균학회지

Chronic dermatophyte infection rarely fails to respond to topical or systemic antifungal therapy. Such refractory condition relates to many factors and one of them is the decreased response of delayed type hypersensitivity. A plausible mechanism by which the delayed hypersensitivity response may cause dermatophyte inhibition has been proposed already. Our patient had skin rashes for 6 years. It was diagnosed as tinea corporis and treated with various systemic antifungal agents, such as griseofulvin, itraconazole, fluconazole, terbinafine and topical forms of econazole and terbinafine. But the skin lesions did not resolve completely and reaggravated frequently. Numerous verrucae planar were found on face, neck and both extremities. Trichophyton rubrum was identified by fungus culture study. Laboratory examination showed no response against multi-CMI test, DPCP sensitization and prick test for trichophytons. We challenged the therapy with the combined antifungal agents and immune stimulatory drugs. This case is thought to be a chronic dermatophyte infection due to the defects in the both cell mediated immunity and immediate type hypersensitivity which is crucial for the host defence mechanisms against fungal infection.

Porokeratotic Eccrine Ostial and Dermal Duct Nevus

A 6-year-old boy with porokeratotic eccrine ostial and dermal duct nevus on the left sole is reported. The patient was born with keratotic plugs, each measuring 1-2 mm in diameter, on the left sole. Light-microscopic examination revealed epidermal invagination and cornoid lamella, which was found to be connected with hyperplastic intraepidermal and dermal eccrine duct. The present case can be histologically differentiated from nevus comedonicus and punctate porokeratotis.

Cutaneous Chylous Reflux / 대한피부과학회지

We describe a case of cutaneous chylous reflux, which is thought to be a kind of primary lymphedema, in a 19-year-old male who had suffered from multiple vesiculobullae and intermittent swelling on scrotum for about 6 years. Histopathologic findings showed multiple dilated lymphatic vascular channels in papillary dermis.

A Clinical Study on Microsporum canis Infections in Wonju City and Neighboring Kangwon Provinces / 대한피부과학회지

During the past 2 years : June, 1985 to May, 1987, 564 cases with dermatophytosis who visited the Dermatology Clinic of Wonju Christian Hospital were studied for Microeporam(M,) canis infection by mycologieal examination. The incidence of M.canis infection found to be 16.3%. The monthly distribotion was the highest in January and lowest in August. The ratio of male to female patient was 1: 1. Most of the cases (80.0%) were found in children under the age of 10. Tinea capitis was the most common clinical type of dermatophytosis caused by M. canis. Patients who had a history of contact with domestic cats (27.5%) or dogs (6.3%) were observed in 27 cases and family infections were observed in 22 cases. The incidence of patients with the noninflammatory and inflammatory lesions in tinea cspitis was similar. Most of patients with tinea corporis exhibited multiple, smaller than 2 cm in diameter, annular patches having pustules or papules.

A Case of Keratoderma Palmoplantaris Striata et Marginata / 대한피부과학회지

We herein report a case of keratoderma showing the combined clinical manifestations of striate and marginal keratoderma. The patient was a 18-year-old giri who about a year ago noticed slightly yellowish, well-circurnscribed, hyperkeratotic plaques on the volar aspect of the fingers and palms of both hands in a linear pattern with bands of hyperkeratotic plaques at the edeges of the 2nd fingers. We also found hyperkeratotic plaques on the both soles which were confined to sites of pressure. She denied a history of any chronic pressure or trauma. There was no family member showing the same clinical features. The histopathological findings from the palm, volsr aspect of finger and a sole revealed marked hyperkeratosis, hypergranulosis, and acanthosis.

Fibrous Hamartoma of Infancy : Report of A Case / 대한피부과학회지

We report a case of fibrous hamartoma of infancy in a 7-month-old male infant, in which a solitary, asymptomatic, walnut-sized, nomal skin-colored plaque occurred on the left middle back for about one month. Histopathologic findings showed the distinctive features of fibrous hamartoma of infancy, ie, trabeculae of dense collagenous tissue, whorls of immature spindle cells within a mucoid matrix, and interspersed mature adipose tissue, in the lower dermis. The lesion was excised without recurrence.
