Cerclage Clamping Using Cerclage Passer for Reduction of Anterior and Posterior Column Fracture / 대한정형외과학회잡지

PURPOSE: Both column and T-shaped acetabular fractures are frequently presented with difficulty in reduction. Incomplete reduction may cause traumatic arthritis in the hip joint, resulting in inferior clinical outcomes. The purpose of this study is to introduce our wiring technique and to report the clinical and radiological outcomes of such technique. MATERIALS AND METHODS: Eight patients who underwent our proposed technique for having acetabular fracture with displaced quadrilateral plate between March 2013 and December 2014 were enrolled. All patients were followed-up more than 1 year. The wire passer was set up from an anterolateral aspect of the iliac crest to the greater sciatic notch, between the abductor muscle and the periosteum. The quadrilateral plate of acetabular fracture was reduced with wiring. Internal fixation was added to the pelvic brim. An analysis of the clinical and radiological outcomes was performed. RESULTS: Reduction was performed within the 3 mm intra-articular step-off in all patients. The mean duration of union was 11.8 weeks (9-15 weeks). Five patients (62.5%) showed excellent results, and radiologically, three patients (37.5%) showed good results, and seven patients (87.5%) showed better than good results. CONCLUSION: The cerclage wiring fixation technique using a large cerclage passer instrument can be a useful and safe reduction method in some cases of acetabular fractures.

The Use of Medical Devices for Medical Skin Care and the Legal Issues / 대한피부과학회지

BACKGROUND: Medical skin care is essential for the treatment of skin diseases all over the world. Medical skin care is also part of medical practice and this must be differentiated from the simple skin care that is given for normal healthy skin. OBJECTIVE: We wanted to discuss medical skin care and the related medical devices and legal issues. METHODS: We reviewed the related laws and regulations, we consulted experts and associations and we analyzed the result of the survey. RESULTS: Legally, medical skin care and simple skin care are well classified. However, many illegal procedures are still performed by non-medical personnel and many adverse effects have been reported as a result. Furthermore, there are no legal restrictions for the performer based on the grade of each medical skin care procedure. CONCLUSION: For the best results and safe procedures, medical skin care must be performed by approved medical equipment under the supervision of a physician or medical personnel. Continuous control and guidance by the government is strongly needed.

A Case of Direct Hypoglossal-Facial Nerve Side-to-End Anastomosis / 대한이비인후과학회지

When a surgeon fails to save intracranial segement of the facial nerve and can not identify the proximal segment of the facial nerve due to severe adhesion or severe brain stem compression by the tumor, the interpositional graft has no place in helping this patient. Hypoglossal-facial nerve (XII-VII) direct side to end anastomosis is the effective facial reanimation technique used in such a case. This technique compensates for the drawbacks of classical XII-VII anastomosis, and the bothersome strong mass movement and hemiparalysis of the tongue. We recently experienced a case where XII-VII direct side-to-end anastomosis was applied. We report our case with literature review.

The Immunohistochemical Study of bcl-2 and p53 Expression of Pilomatricoma / 대한피부과학회지

BACKGROUND: The pathogenesis of pilomatricoma is unknown. Several reports have suggested that apoptosis may play a role in the pathogenesis of pilomatricoma. As the bcl-2 and p53 are well-known regulators of apoptosis, a disturbance in either bcl-2 or p53 could compromise a proper apoptotic response and relate to the development of the tumor. OBJECTIVE: The purpose of this study was to evaluate the expression of bcl-2 and p53 proteins in pilomatricoma. METHODS: Paraffin blocks of 14 cases of pilomatricoma were stained immunohistochemically by using anti-bcl-2 and anti-p53 antibodies. RESULTS: 1. Histologically, SCs were found in all 14 pilomatricomas, while BCs and TCs were found each in 9 tumors. 2. All the SCs found in 14 tumors and all the TCs found in 9 tumors were unstained for both bcl-2 and p53. 3. The expression of bcl-2 in 9 tumors was variable. Basal BCs showed reactivity from negativity(-) to strong positivity(+++) and suprabasal BCs showed reativity from negativity(-) to moderately strong(++) positivity. Both basal BCs and suprabasal BCs showed negativity for bcl-2 in 3 tumors and similar positive staining in 1 tumor, while basal BCs showed stonger positivity than suprabasal BCs in 5 tumors. 4. The expression of p53 in 9 tumors was also variable. Both basal BCs and suprabasal BCs showed reactivity from negativity(-) to moderately strong positivity(++). Both basal BCs and suprabasal BCs showed negativity for p53 in 1 tumor and similar positive staining in 6 tumors, while suprabasal BCs showed stronger positivity than basal BCs in 2 tumors. CONCLUSION: The above immunohistochemical findings showed that the expression of bcl-2 and p53 was variable and suggest that both bcl-2 and p53 have a limited role in the control of apoptosis in pilomatricoma.

A Case of Squamous Papilloma in the Middle Ear, External Auditory Canal, and Infratemporal Fossa / 대한이비인후과학회지

Papilloma is a benign neoplasm confined almost exclusively to the sinonasal tract. And rare cases involving middle ear or external auditory canal, usually extended or contaminated from nasal cavity have been reported. We recently experienced a case of squamous papilloma involving middle ear, external auditory canal, and infratemporal fossa without any evidence of involving sinonasal tract. We present a review of literature and discuss the pathophysiology of the papilloma.
