This study was performed to investigate associations between serum alpha(1)-antitrypsin(AAT) concentration and radiological categories of coal workers' pneumoconlosis(CWP), between AAT concentration and pulmonary complications such as tuberculosis and emphysema, and to study associations between AAT concentration and FEV(1.0)% in CWP patients, We classified 254 CWP patients in D Hospital into categories of small opacity profusion. And we selected 86 subjects by with or without emphysematous finding in each categories by proportional stratified sampling method. Semm AAT concentrations were quantkated by single radial immunodiffusion method, and the findings of chest radiographs were evaluated by radilogist. The results were as follows: 1. Serum AAT concentrations were not significantly different among groups of radiological categories of small opacities. 2. Complication of emphysema was associated with smoking habits sigmficantlyl(chi square=12.16, p<0,01). And AAT concentraLion was higher in smokers and ex-smokers than in non-smokers. Serum AAT concentration was significantly higher in the cases with emphysema than in the cdses without emphybema{p<0.01). 3. Serum AAT concentration of the group with active pulmonary tuberculosis was significantly higher than with inactive or without: pulmonary tuberculosis group(p<0.1). 4. Serum AAT concentration of the group with low FEV(1.0)% was significantly higher than with high or normal group(p<0.05).

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: Spatial hearing refers to the ability to understand speech and identify sounds in various environments. We assessed the validity of the Korean version of the Spatial Hearing Questionnaire (K-SHQ). MATERIALS AND METHODS: We performed forward translation of the original English SHQ to Korean and backward translation from the Korean to English. Forty-eight patients who were able to read and understand Korean and received a score of 24 or higher on the Mini-Mental Status Examination were included in the study. Patients underwent pure tone audiometry (PTA) using a standard protocol and completed the K-SHQ. Internal consistency was evaluated using Cronbach's alpha, and factor analysis was performed to prove reliability. Construct validity was tested by comparing K-SHQ scores from patients with normal hearing to those with hearing impairment. Scores were compared between subjects with unilateral or bilateral hearing loss and between symmetrical and asymmetrical hearing impairment. RESULTS: Cronbach's alpha showed good internal consistency (0.982). Two factors were identified by factor analysis: There was a significant difference in K-SHQ scores for patients with normal hearing compared to those with hearing impairment. Patients with asymmetric hearing impairment had higher K-SHQ scores than those with symmetric hearing impairment. This is related to a lower threshold of PTA in the better ear of subjects. The hearing ability of the better ear is correlated with K-SHQ score. CONCLUSION: The K-SHQ is a reliable and valid tool with which to assess spatial hearing in patients who speak and read Korean. K-SHQ score reflects the severity and symmetry of hearing impairment.

Sinonasal teratocarcinosarcoma is extremely invasive malignant tumor that has a histological characteristic of having both more than one epithelial and mesothelial tissue components. It is a rare cancer of having less than 50 cases reported until now and domestically. This case presents a 51 year-old male who had nasal stuffiness for 2 months. A mass was noticed in his right nasal cavity, and histopathologic findings revealed the mass as a teratocarcinosarcoma. Computed tomography and magnetic resonance imaging showed that the mass originated from right nasal septum and did not invade the sinuses and that it was touching the inferior turbinate. No cervical lymph node metastasis was observed (T2N0M0, Stage II). Wide excision of the mass was performed, and no invasion in the resection margin was confirmed. Radiotherapy was performed postoperatively. Currently, the patient has been followed up on a regular basis for 28 months. Thus, the authors present a report of very rare sinonasal teratocarcinosarcoma.

BACKGROUND: The use of autogenous cartilage has the problem of donor site morbidity and limited supply in reconstructive surgery. OBJECTIVES: The purpose of this study is to increase the size and the volume of the autogenous small cartilage by the new three dimensional culture technique. MATERIALS AND METHODS: The chondrocytes from biopsied human septal cartilage were subcultured. The increased cells were encapsulated with calcium alginate and were injected to the subcutaneous tissue of the athymic nude mouse for in vivo 3-dimensional culture. RESULTS: After 8 weeks of the injection, the implanted subcutaneous nodule was seemed to be the natural cartilage and the histoarchtectures revealed characteristics of the hyaline cartilage. CONCLUSION: This results suggest that the small biopsied cartilage can be expanded by the techniques of subculture and the 3-dimensional culture., and can potentially overcome the limited availability of autogenous donor cartilage.

Melnick-Fraser syndrome is a rare congenital anomaly that is characterized by preauricular fistula, branchial fistula, hearing impairment, and is often combined with renal anomaly. Preauricular fistula and branchial fistula can occur in the same individual, but their association with hearing impairment is very rare. The condition is inherited in an autosomal dominant mode. Recently, we experienced a case of Melnick-Fraser syndrome in a 32 years old male patient with familial tendency. We report this case with a review of literature.
