The nasal tips of Orientals are different from those of caucasians with are characterized by flat nose and bulbous nasal tip appearance because of its thick and tense skin, shory columella, flaring of nostrils, and restriction of nasal tip projection due to underdevelopement of medial crus of alar cartilage. For better nasal tip definition and projection, alar carilage must be realigned and tip might be augmented with autogenous cartilage onlay graft. Furthermore in patient with short columella, strut formation might be performed because the nostril comprises two-thirds of height of nasal tip. If the nasal tip is prjected without lengthening of columella, sometimes we noted unnaturally tented appearance of nasal tip may result. Also for the soft tissue lengthening in columella in proportion to the nasal tip projection, the short columella can be lengthened with columella based V-Y advancement. Surgical approach through alar rim incision or open rhinoplasty incision may be employed depending upon the severity of tip defomity. If flattening is severe to enough require lengthening of the columella, open rhinoplasty incision is the best choice. Through the incision, the alar cartilage is dissected freely from the skin and vestibulsr mucosa. Cartilage grafts are performed using carilage onlay graft or columella strut formation after transdormal fixation suture. This study presents clinical cases of various nasal tips in the view of nasal tip deformity which were corrected with various operative methods using combined technique of approximating the alar cartilage and a multilayered autogenous onlay cartilage graft on the nasal tip harvested from the auricular cartilage, also Silicone implant was used for augmetation of nasal dorsum and columella strut formation with columella base V-Y advancement. The ten years of our experience with nasal tip plasty in over one hundred patient showed excellent result and no complications were observed during post operative follow-up so we are reporting these cases with review of literature.

As the elderly population continues to grow, the number of geriatric patients reported to poison centers continues to increase. Older poisoned patients are at an increased risk of death compared to younger adult patients. The purpose of this paper is to report a case of hydrofluoric acid poisoning along with a discussion of poisoning characteristics. A 79 year-old male with dementia visited emergency department presenting epigastic discomfort after ingestion of 50% hydrofluoric acid solution. At admission, he presented with a stable vital sign but progressed to pulseless electrical activity. In spite of advanced resuscitation efforts and administration of calcium gluconate, he rapidly detoriated and died 3 hours after the ingestion.

Various cancer types have been associated with cancer-related cerebral infarction. In this study, we
describe the first case of cancer-related cerebral infarction in which the underlying disease was primary
bone marrow lymphoma (PBML). A 79-year-old man presented with abruptly developed bilateral lower
extremity weakness and confusion. Diffusion-weighted imaging on admission showed multiple cortical
and subcortical embolic infarction lesions in multiple vascular territories. Diagnostic evaluations to
determine the embolic source revealed no abnormalities. Laboratory testing demonstrated elevated
D-dimer (2.59 μg/mL) but no other prothrombotic abnormalities. In suspicion of cancer-related stroke,
we performed chest CT, abdomen CT, and FDG-PET to detect the hidden malignancy. Findings
revealed no evidence of cancer; however, they did reveal signs of anemia (hemoglobin 9.0 g/dL).
Bone marrow aspiration biopsy showed large atypical B cell involvement suggestive of high-grade B
cell lymphoma. The patient was diagnosed with primary bone marrow diffuse large B-cell lymphoma
initially presenting with ischemic stroke. Our case suggests that primary bone marrow cancer may be a
candidate for the differential diagnosis of hidden malignancy in patients with suspected cancer-related
stroke. Bone marrow biopsy may be essential for establishing an appropriate differential diagnosis in
patients with abnormal hematologic findings.

Myxedema coma is the extreme form of untreated hypothyroidism. In reality, few patients present comatose with severe myxedema. We describe a patient with myxedema coma which was initially misdiagnosed as a brain stem infarct. She presented to the hospital with alteration of the mental status, generalized edema, hypothermia, hypoventilation, and hypotension. Initially her brain stem reflexes were absent. After respiratory and circulatory support, her neurologic status was not improved soon. The diagnosis of myxedema coma was often missed or delayed due to various clinical findings and concomitant medical condition and precipitating factors. It is more difficult to diagnose when a patient has no medical history of hypothyroidism. A high index of clinical suspicion can make a timely diagnosis and initiate appropriate treatment. We report this case to alert clinicians considering diagnosis of myxedema coma in patients with severe decompensated metabolic state including mental change.

A 47-year-old woman ingested about 12 mg of colchicine with suicidal intent. Colchicine, a highly poisonous alkaloid, is a commonly used treatment for gout, Bechet's disease, and familial Mediterranean fever. Despite the knowledge of its side effects, the risk of a significant overdose is under-appreciated. She suffered from acute multisystem toxicity, including gastrointestinal disorders, bone marrow suppression, alopecia, and probable pancreatitis, but she ultimately recovered with supportive therapy. We report a case of acute colchicine toxicity from a single overdose with a review of the literature.

PURPOSE: Chlorine gas is a common irritant that usually causes mild respiratory symptoms. One severe symptom, RADS (Reactive Airway Dysfunction Syndrome), is not well known to physicians. We analyzed the clinical features of chlorine gas exposure. METHODS: We prospectively collected 25 cases of chlorine gas exposure near our emergency center on January 10th, 2007, and analyzed demographic data, event-to-ER interval, symptoms, and laboratory results based on medical records. RESULTS: Only 2 patients out of 25 were admitted because of severe symptoms, the rest were discharged without complications. Sixty percent of them visited the ER within 12 h of exposure. The most common symptoms were chest discomfort (60%), headache (40%), nausea (40%), throat irritation (26%), and cough (32%). Two out of eight dyspnea cases showed abnormal pulmonary function, but only one case was diagnosed as RADS. CONCLUSION: Most symptoms after chlorine gas exposure can be treated conservatively. However, patients with chlorine exposure should be followed up long term for delayed complications.

Early recognition of coalescence in pneumoconiotic lesions is important because such coalescence is associated with the respiratory symptoms and deterioration of lung function. This complicated form of pneumoconiosis also has worse prognosis than does simple pneumoconiosis. High resolution computerized tomography(HRCT) provides significant additional information on the stage of the pneumoconiosis because it easily detects coalescence of nodules and emphysema that may not be apparent on the simple radiograph. The Purpose of this study is to clarify the role of HRCT in detection of large opacity and the relationship of change between the coalescence of nodules or emphysema and lung function in dust exposed workers. 1. There was good correlation between the HRCT grade of pneumoconiosis and ILO category of profusion. 5(9.09%) in 55 study population had confluent nodule extending over two or more cuts on HRCT. HRCT could identify the pneumoconiotic nodules which was not found by simple radiography in 6 workers with category 0/0. 2. No significant difference was observed coalescence of nodules and emphysema by dust type. 3. There was no significant difference in pulmonary function according to ILO and HRCT classification. 4. HRCT could detect the significant reduction in FEV1, FEV1/FVC, PEER, FEF25, FEF50, and FEF75 and remarkable increase in RV and TLC in study persons with emphysema compared with non-emphysema group. 5. Emphysema was found more often in nodules-coalescence group than small opacity group by HRCT. We found that HRCT could easily detect areas of coalescence and complicated emphysema compared to plain chest X-ray. Also our data suggest that it is primarily the degree of emphysema rather than the degree of pneumoconiosis that determines the level of pulmonary function.

OBJECTIVES: To develop dedicated markup language for clinical contents models (CCM) to facilitate the active use of CCM in electronic health record systems. METHODS: Based on analysis of the structure and characteristics of CCM in the clinical domain, we designed extensible markup language (XML) based CCM markup language (CCML) schema manually. RESULTS: CCML faithfully reflects CCM in both the syntactic and semantic aspects. As this language is based on XML, it can be expressed and processed in computer systems and can be used in a technology-neutral way. CONCLUSIONS: CCML has the following strengths: it is machine-readable and highly human-readable, it does not require a dedicated parser, and it can be applied for existing electronic health record systems.

Objective:
It is essential to measure the effect of burnout on doctors because burnout can affect doctors’ mental health as well as the functioning of medical practice. This study aims to validate a Korean version of the single-item burnout measure (SIBM), which was developed to quickly measure the level of burnout among doctors.
Methods:
Through an online survey, a self-report questionnaire was administered to 324 public health doctors in Korea. The Korean version of the SIBM was validated against the Maslach Burnout Inventory-General Survey (MBI-GS), the Patient Health Questionnaire-9 (PHQ-9), the Generalized Anxiety Disorder-7 (GAD-7) screening tool, the Perceived Stress Scale (PSS), and the Vaccination Attitudes Examination (VAX) scale. Pearson correlation coefficients and analysis of variance (ANOVA) were used to determine the association between the SIBM and other scales. ANOVA was additionally used to determine the associations between the subscales of the MBI-GS and those of the SIBM.
Results:
The correlation coefficient between the SIBM and the MBI-GS, PHQ-9, GAD-7, and PSS was positive (p<0.01), and the correlation coefficient between the SIBM and the VAX scale was not significant. Therefore, convergent and discriminant validity was verified. Exhaustion and cynicism, which were correlated with the SIBM, with r2=0.43 (p<0.01) and 0.48 (p<0.01), yielded R2 scores of 0.27 (p<0.01) and 0.20 (p<0.01) in ANOVA.
Conclusion
The Korean version of the SIBM is an appropriate screening tool for burnout. It can be evaluated in a short time, thereby enhancing continuous follow-up observations and response rates to burnout.
