Zygomatic arch is a prominent structure among facial bone and this is the major cause of vulnerability from the facial trauma. The fracture of zygomatic arch has been treated by ancillary methods of closed reduction approaching through temporal incision or intraoral incision. But, these methods gas a limitation of reduction force vector and it has a difficulty in maintaining the secure fixation of the reduced unstable fractured bones. All 22 cases of zygomatic fracture were reduced by transcutaneous screw and fixed with external fixation device successfully. There was no post-operative complication, such as non union, malunion, and visible scar. This method also has advantages of less post-operative edema and pain.

Medial orbital wall fracture was described by Converse and Smith in the first time in 1957. These fractures which comprise more than 30% of all the orbital wall fracture are may easily be overlooked in routine orbital radiology. Accordingly, examination with orbital CT is essential for accurate diagnosis and appropriate treatment. These type of fracture are followed frequently by post-oprative complication such as diplopia and enophthalmos because it is very difficult to approach to orbital medial was in these operations. The mechanism of the orbital wall fractures are abruptly increased hydraulic pressure by sudden impact on orbital rim or soft tissue of orbital region. So patients who show the signs of subcutaneous emphysema, edema on the orbital region or diplopia need to get through examination with orbital CT for accurate diagnosis and immediate reconstruction of the fractured orbital wall. Conventional approaches in the operations of the orbital medial wall fractures are that with bicoronal incision, subciliary incision, transconjunctival incision and infra-orbital rim incision. But, approach with bicoronary incision, needs broader dissection and longer time for operation. Operations with transconjunctival incision and that with subciliary incision have difficulty to approach to fractured sites. Operations with other conventional methods may be also followed by scar problem. The authors performed reduction and reconstruction of the fractured orbital medial wall fractures successfully without any complications and difficulties by intra-eyebrow approach with which they made incision of 2 - 2.5 cm on mid-area of eyebrow to expose fractured medial wall with good operative field.

PURPOSE: Sexual differences in the incidence and crystalline composition of urinary stones in humans are well-known, but it is unclear why men have a higher incidence of calcium oxalate stones than women. We investigated the effects of male sex hormones on stone formation using an ethylene glycol (EG) - induced urolithiasis model in rats. MATERIALS AND METHODS: Adult male Sprague-Dawley rats were divided into 4 groups, each containing 10 rats. One group of rats was left untreated and served as control. The other 3 groups were fed a 1% ethylene glycol (EG) lithogenic diet for 4 weeks. Among these, one group was non-castrated, one group was castrated and one group was non-castrated and given finasteride orally. Serum testosterone, creatinine, electrolytes, 24-hour urine levels of oxalate and citrate, and creatinine clearance were measured. The crystal deposits were examined by light and polarizing microscopes. RESULTS: Testosterone promoted calcium oxalate stone formation in EG - treated rats. Finasteride administration significantly decreased urinary oxalate excretion and calcium oxalate deposition, compared with controls. Urinary citrate was significantly decreased in EG-treated rats, but was not influenced by castration or administration of finasteride. There were no significant differences in serum concentrations of creatinine, sodium, or potassium among the control and experimental groups. CONCLUSIONS: Our data suggest that testosterone promotes calcium oxalate stone formation, and that dihydrotestosterone may be partially responsible for the exaggerated hyperoxaluria in EG-treated rats. Additionally, male sex hormones have a lesser influence on urinary citrate than oxalate.

We present a case of carcinoma erysipelatoides which or iginated from an internal organ. The patient was a 50 year-old female who had peritoneal carcinomatosis, She presented an erythematous lesion resembling erysipelas on her right breast. Histopathologic findings were consistent with metastatic adenocarcinoma but clinically it was not associated with carcinoma of the breast.

Although nearly 100 cases of prurigo pigmentosa have been reported in Japan, there has been no report in Korea. Recently, we exporienced two cases of prurigo pigmentosa in Korean women of 27 and 20 years of age. Histopathological findings of reddish papules showed exocytosis, inter and intra-cellular edema in the epidermis, liquefaction degeneration of the basal cell layei and perivascular round cell infiltration in the dermis. The specimens from the pigmented lesions show merely incontinence of pigments and mild perivascular round cell infiltration. We treated two patients with oral antihistamines and topical corticosteroids. One patient showed complete regression after 8 months of treatment but the other patient was lost for follow up.
