OBJECTIVES: A different sequence change, in the mitochondrial tRNA gene, has been proposed as a candidate mutation in the sensorineurnal hearing loss. The purpose of current study is to identify the association between the noise-induced sensorineurnal hearing loss and the A to G mutation at nucleotide 3243 of mitochondrial DNA. METHODS: Subjects were established by history and chart review, and audiological and clinical data were obtained. Blood was sampled from 101 controls, 50 noise-induced hearing loss, and 12 sensorineural deafness. The DNA of these individuals was extracted, and mitochondrial genome was analyzed by polymerase chain reaction. Subsequently, the coding sequence of mitochondrial genome was sequenced, and compared to the normal sequence, and all sequence variations were analyzed by restriction endonuclease ApaI. RESULTS: Mitochondrial DNA mutation (3243A->G) was not detected by polymerase chain reaction (PCR) in any patients with noise-induced hearing loss, sensorineural hearing loss, and normal control without hearing loss in Koreans. The DNA sequencing of PCR products did not revealed an A to G substitution at nucleotide 3243 of mitochondrial DNA. CONCLUSIONS: The noise-induced sensorineural hearing loss was not associated with mitochondrial DNA mutation (3243A->G)

BACKGROUND: Neer type II distal clavicle fractures have the drawback of coracoclavicular instability and insufficient distal bony fragment, thereby making it difficult to achieve adequate fixation. Although various surgical treatments have been described for Neer type II fracture, the optimal treatment remains controversial. This study reports the clinical results and usefulness of anatomical locking plate with additional K-wire fixation. METHODS: A totally of 21 patients with type II distal clavicle fracture were included in the study. The surgical procedure reduced the fracture temporarily; it included insertion of one or two K-wire from the lateral margin of the distal fragment to the proximal fragment through the fracture site, followed by application and fixation of the locking plate. The bony union and migration of K-wire was evaluated in the follow-up radiography. The coracoclavicular distance and acromioclavicular joint arthrosis were assessed at the final follow-up. The Constant Score (CS) and Korean Shoulder Score (KSS) were evaluated for clinical scoring. RESULTS: Bone union was achieved in all cases. At the final follow-up, coracoclavicular distance of the injured shoulder was increased, as compared to the intact shoulder (p=0.002), with no accompanying clinical symptoms. No K-wire migration was observed. At the final follow-up, K-wire irritation was observed in two cases and acromioclavicular arthrosis in one case, with no other adverse effects. Pain visual analogue scale, CS, and KSS were improved in all cases. CONCLUSIONS: The method of anatomical locking plate with additional K-wire fixation could be useful in achieving beneficial clinical results.

Nevus lipomatosus cutaneous superficialis(NLCB) is a rare condition consisting of ectopic fat tissue in the dermis and having the predilection for the pelvic girdle, especially gluteal region. The patient was a 20 year-old female. About 8 years prior to the first visit she had noticed the rice-sized papules on her lower back, which had been gradually increased in size and coalesced to become two, cerebriform, skin colored to yellowish tumor masses of soft consistency, distributed on both sides of the midline of lower back, and measuring respectively 3.5X7.Qcm and 7.0x11.5cm in size. Jihe biopsy specimen taken from the tumor mass revealed the ectopic presence of fat lobules occupying half of the reticular dermis. The fat lobules consisted of almost mature fat cells with the presence of dilated capillaries in their centers.

Brodie's abscess is a primary subacute pyogenic osteomyelitis that has a thin wall of fibrous tissue and sclerotic bone. The authors have encountered a case of a Brodie's abscess that was developed in the same place of both tibia at the same time and treated the case with surgery and continuous closed irrigation.

Severe injuries of hands frequently expose the bone and joint due to the defect of crushing of soft tissues. Although the several methods are introduced, the treatment of bone and joint exposure of finger and hand is very difficult to control satisfactorily. From October 1986 to February 1988, we performed the pedicled skin flap in 11 cases; 9 abdominal skin flaps and 2 pectoral skin flaps. Follow up stuides showed good results. The successful surviving of flaps was accomplished in all cases and the dead bones were regenerated by the creeping substitution. Therefore this pedicled skin flap operation can be considered to be a simple and effective method in treating the bone and joint exposure of fingers.

Darier's disease is a well-known genodermatosis characterized by recurrent waxy, hyperkeratotic papules usually occurring over the seborrheic area. The major histopathological changes are characteristic acantholysis and dyskeratosis which are diagnostic of the disease with typical clinical features. There are less common variants including the hypertrophic, vesicobullous and linear type. However, comedonal lesions are very rare. We report an unusual case of Darier's disease, which showed prominent comedonal papules and plaques over the face, scalp and upper trunk with the typical findings of Darier's disease.

The characteristics of modern society's trauma is a propensity for multiple and severe trauma, specially, the fatal damage accompanied by facial bone fracture. We observed the malocclusion owing to delayed prompt treatment If the fractured fragments is crushed severely, it is difficult to make them positioned into the normal anatomical states and to fix them tightly. Post-traumatic malocclusion is usually caused by a delay in treatment and inadequate anatomic reduction. Inadequately treated facial bone fractures result in facial disfiguring and functional impairment of mastication and speech.We performed 27 cases of correction of post-traumatic malocclusion between April 1994 and June 1996. We used various operative techniques such as anterior segmental osteotomy, Le Fort osteotomy, maxillary segmental osteotomy and mandibular sagittal split osteotomy. If the malocclusion was due to disarrangement segmental osteotomy. If that malocclusion was attributed to a malpositioned skeletal bone, we take maxillary segmental osteotomy or mandibular sagittal split osteotomy. We acquired the desirable occlusion first followed by a fixation between the mandible and maxillary skeletal bones with the bite block. The aim in the correction of malocclusion was to create a harmony of centric relation and centric occlusion. After operation, intermaxillary fixation with bite block have many advantages in the treatment of malocclusion.

The inverted nipple presents many problems including both cosmetic and functional aspects and impairment in breast feeding. the histopathologic characters of inverted nipple are that inverted nipple has less fibromuscular tissue than normal nipple and has short lactiferous duct and dense fibrous tissue. Many surgical and non-surgical techniques have been designed for correction of the inverted nipple. But most of these techniques have produced unsatisfactory problems. especially undesirable recurrence is most important problem. We experienced 19 inverted nipples in 12 patients between March 1995 and January 1998. We combined modified Teimourian method, purse-string suture and Z-plasty. and had good result for 3weeks to 30months follow up. This method was effective for correction of the inverted nipple with low recurrence rate and simple techniques.
