Neonatal lupus erytematosus is a distinct subset of lupus erythematosus. It is characterized by cutaneous findings exhibiting the morphology of subacute cutaneous lupus erythematosus, congenital heart block, and anti-Ro/SSA and/or anti-La/SSB autoantibodies which result from the transplacental passage of maternal autoantibodies. We report a case of a 12-week-old female infant who presented with characteristic clinical and histopathological features of cutaneous neonatal lupus erythematosus but without evidence of congenital heart block. Initial serological studies reveled the presence of anti-La/SSB anti-bodies and antinuclear antibodies. 5 months later, follow-up serology was negative in accordance with a clinical remission.

Nowadays shoulder ultrasound is commonly used in the assessment of shoulder diseases and is as accurate as magnetic resonance imaging in the detection of several pathologies. Operator dependence is the main disadvantage of shoulder ultrasound. After adhering to a strict examination protocol, good knowledge of normal anatomy and pathologic processes and an awareness of common pitfalls, it can be used as a focused examination providing rapid, real-time diagnosis, and treatment by ultrasound-guided interventions in desired clinical situations. Also shoulder ultrasound can help the surgeon decide whether treatment will be surgical or nonsurgical. If arthroscopy is planned, sonographic findings help to counsel patients regarding surgical and functional outcomes. If a nonsurgical approach is indicated, ultrasound can be used to follow patients. This review article presents the examination techniques, the normal sonographic appearances and the main pathologic conditions found in shoulder ultrasound. And also addresses a simplified approach to scanning and ultrasound-guided intervention. Knowledge of optimal techniques, normal anatomy, dynamic maneuvers, and pathologic conditions is essential for optimal performance and interpretation of images.

OBJECTIVES: Manganese is cytotoxic to the central nervous system including basal ganglia. Its toxic mechanism is related to oxidative stress, mediated by toxic free radicals but is specultives. In the present study, we have investigated to manifest apoptosis in manganese-induced cytotoxicity in primary neuronal cell culture of rat basal ganglia. METHOD: To detect apoptotic neuronal cells were stained by the terminal deoxynu-cleotide(TdT)-mediated dUTP nick end-labelling(TUNEL) method and apoptotic changes in nuclei of neurons were observed by electron microscopy. RESULTS: We showed that TUNEL immunostain showed brownish signal in the nuclei of apoptotic cells and the proportions of apoptotic cells in Manganese treatment groups were more higher than controls. On transmission electron microscopy, there were chromatine condensation with margination toward nuclear membrane and condensation of cytoplasm in the treated with luM MnC1, for 48 hours in a basal ganglia neurons. Apoptotic bodies were found and consisted of semilunar-like condensed nuclei with relatively intact cytoplasmic organelles. CONCLUSIONS: Apoptosis appears to be one mechanism in the manganese-induced neuronal cell death. Manganese intoxication is a convenient model for apoptosis study.

Zygomatic fractures are the second most common facial bone fractures encountered and treated by plastic surgeons. Stable fixation of fractured fragments after adequate exposure is critical for ensuring three-dimensional anatomic reduction. Between January 2008 and December 2010, 17 patients with zygomatic fractures were admitted to our hospital; there were 15 male and 2 female patients. The average age of the patients was 41 years (range, 19 to 75 years). We exposed the inferior orbital rim and zygomatic complex through a lateral brow, intraoral, and subciliary incisions, which allowed for visualization of the bone, and then the fractured parts were corrected using the Carroll-Girard T-bar screw. Postoperative complications such as malar asymmetry, diplopia, enophthalmos, and postoperative infection were not observed. Lower eyelid retraction and temporary ectropion occurred in 1 of the 17 patients. Functional and cosmetic results were excellent in nearly all of the cases. In this report, we describe using the Carroll-Girard T-bar screw for the reduction of zygomatic fractures. Because this instrument is easy to use and can rotate to any direction and vector, it can be used to correct displaced zygomatic bone more accurately and safely than other devices, without leaving facial scars.

The external laryngeal trauma is a rare but clinically important injury. The blunt trauma is more common than penetrating one. As other trauma, early suspicion and accurate diagnosis of acute laryngeal and tracheal injuries are crucial. If the airway obstruction is impending, secure airway should be made before diagnosis or treatment. The computed tomography scans play an important role in diagnosis and combined cervical esophageal injury should be evaluated. Proper restoration of the laryngeal framework with appropriately timed open reduction and internal fixation is critical for optimal recovery of the airway, voice, and swallowing.

PURPOSE: Median nerve entrapment syndrome within carpal tunnel is usually called carpal tunnel syndrome and it is the most common form of peripheral nerve entrapment syndrome. Many factors such as diabetes mellitus, hypothyroidism, hormonal replacement theraphy, corticosteroid use, rhematoid arthritis and wrist fractures may cause carpal tunnel syndrome. To the best of our knowledge, this is the first case report of median nerve entrapment syndrome due to adhesion of laceration wound after suicidal attempt. METHODS: A 28-year-old woman presented with a sensory change and thenar hypotrophy on her left hand. On her history, she attempted suicide by slashing her wrist. Initial electromyography (EMG) showed that the nerve conduction velocities of median nerve was delayed. Therefore, we performed surgical procedures. When exploration, Fibrous scar tissue observed around the median nerve but nerve had not been injured. Transcarpal ligament was completely released and adjacent fibrous tissue was removed to decompress the median nerve. RESULTS: The postoperative course was uneventful until the first year. Opposition difficulty and thenar hypotrophy were improved progressively after the surgery. Sensory abnormality was slowly improved over one year. CONCLUSION: We report a case of median nerve entrapment syndrome that was caused by adhesion of laceration wound after suicidal attempt. This is an unusual cause of median nerve entrapment syndrome, the symptoms were relieved after transcarpal ligament release and fibrous scar tissue removal.

PURPOSE: According to the data presented by ministry of justice, a number of foreign workers in Korea is approximately 700 thousands and among them 22 thousands are illegal workers. We would like to provide the basic information the foreign workers by analyzing clinical contents. METHODS: 1456 patients who visited the hospital were reviewed by nationality, medical department, gender and age. 62 patients have visited plastic surgery department and they were additionally reviewed by diagnosis, chief complant and operation. RESULTS: Mongolians were 388 cases (26.7%), followed by Chineses with 452 cases (31.1%). General surgery had 264 visits (18.1%) followed by internal medicine with 388 visits (26.6%). In gender grouping, 781 patients were males and 675 patients were females. Hand, face and extremity injuries were common in plastic surgery field but many foreign worker patients also wanted to take aesthetic surgery such as scar revision, blepharoplasty and augmentation rhinoplasty. CONCLUSION: It has been twenty years since foreign workers have come to the Korean society. In the past foreign workers were mostly neglected. However with the vast improvement in labor and welfare related services, demands for plastic surgery, especially aesthetic surgery are increasing among foreign workers. Therefore plastic surgeons' continuous interest in foreign workers is required.

OBJECTIVES: In an effort to improve hearing aid users’ satisfaction, recent studies on trainable hearing aids have attempted to implement one or two environmental factors into training. However, it would be more beneficial to train the device based on the owner’s personal preferences in a more expanded environmental acoustic conditions. Our study aimed at developing a trainable hearing aid algorithm that can reflect the user’s individual preferences in a more extensive environmental acoustic conditions (ambient sound level, listening situation, and degree of noise suppression) and evaluated the perceptual benefit of the proposed algorithm. METHODS: Ten normal hearing subjects participated in this study. Each subjects trained the algorithm to their personal preference and the trained data was used to record test sounds in three different settings to be utilized to evaluate the perceptual benefit of the proposed algorithm by performing the Comparison Mean Opinion Score test. RESULTS: Statistical analysis revealed that of the 10 subjects, four showed significant differences in amplification constant settings between the noise-only and speech-in-noise situation (P<0.05) and one subject also showed significant difference between the speech-only and speech-in-noise situation (P<0.05). Additionally, every subject preferred different β settings for beamforming in all different input sound levels. CONCLUSION: The positive findings from this study suggested that the proposed algorithm has potential to improve hearing aid users’ personal satisfaction under various ambient situations.
