Background: The epidemiology of tuberculosis (TB) has been assessed based on the data of the analysis of TB patients notified to the surveillance system in Korea. However, the national status of TB is not validated through this surveillance system. The objective is to determine the epidemiology of TB and to understand the accurate status of TB patients treated in private institutions. Methods: Medical records of 53,579 patients who had been diagnosed with TB in 2008 were analyzed. Results: Among 53,579 patients, the number of sputum smear positive cases was 15,639(29.2%) and the number of new cases was 39,191 (73.1%). The drug resistance rate of new cases was 5.3%, while the rate stood at 13.3% for TB patients with treatment history. The number of multi-drug resistant TB (MDR-TB) patients was 2,472 (4.6%), which consists of 2.9% of new cases and 9.3% of TB patients with prior treatment history. The number of extensively drug-resistant TB patients was 749 (1.4%), consisting of 1.1% of new cases and 2.2% of TB patients with prior treatment history. In terms of treatment outcomes, 66.4% of all TB patients, 70.5% of new cases, 64.4% of relapse cases, and 46.8% of MDR-TB cases were cured or completed. It was inferred that in 2008, the total number of TB patients reached 70,767, 145.6 per 100,000 people (95% confidence interval, 145.5~145.7). Conclusion: We conclude that the medical records review of the Health Insurance Review and Assessment Service (HIRA) data can be very effective in promoting the understanding of the current status of TB in private institutions.

Purpose: This study aimed to determine new criteria for detecting independent factors with high sensitivity in cases of cervical spine injury. We compared the sensitivity, the specificity, and the false negative predictive value (NPV) of plain radiographs with those of computed tomography for cervical spine injury in patients with minor head injury. Methods: We retrospectively reviewed the cases of 357 patients who underwent both cervical plain radiographs and computer tomography from January 2006, to September 2008. Patients were divided into two groups: the cervical spine injury group and the no cervical spine injury group. New criteria were organized based on variables that had significant differences in the logistic regression test. Results: Among the 357 patients, 78 patients had cervical spine injuries. The average age was $43.9{\pm}15.2$ yrs old, and the male-to-female ratio was 1.90. The most common mechanism of injury was motor vehicle accidents. There was a significant difference in loss of consciousness, Glasgow Coma Scale (GCS)=14, neurologic deficit, posterior neck tenderness, and abnormality of the cervical plain radiographs between the two groups on the logistic regression test. New criteria included the above five variables. If a patient has at least variable, the area under the ROC curve of the new criteria was 0.850, and the sensitivity and the false NPV were 87.2% and 5.2%, respectively. Conclusion: New criteria included loss of consciousness, GCS=14, neurologic deficit, posterior neck tenderness, and abnormality of the cervical plain radiographs. If the patient had at least 1 variable, he or she could have a of cervical spine injury with a sensitivity of 87.2% and a false NPV of 5.2%.

Background: Minimally invasive direct coronary artery bypass surgery(MIDCAB) has been increasing in interest along with the new techniques in myocardial immobilization for easier and safer procedures. Until the opening of the era of new techniques, adequate accuracy and good patency of grafts were debatable. Our experiences of MIDCAB were studied according to the stages of technical developments. Material and Methods: Since March 1996, 55 patients have undergone MIDCAB procedures. The patients of off-pump CABG(no cardiopulmonary bypass under full sternotomy) were excluded from the study. In the early experience(Stage I), a left anterior small thoracotomy through the left parasternal incision was performed(n=6); then an approach through the lower partial sternotomy was used(Stage II, n=33); and recently, a chest wall elevator for harvesting the internal thoracic artery and the foot plate for myocardial immobilization have been used(USSC, Norwalk, CT)(Stage III, n=16). Result: The surgical procedures of four patients in the Stage II group have been converted to conventional bypass because of the deeply seated left anterior descending coronary artery in two patients, fracture of the calcific lesion in the right coronary artery in one patient, and a cardiogenic shock during hypothermia in the other patient with ventricular dysfunction. Two patients in stage II experienced symptomatic recurrences after surgery and restenosis was verified on angiocardiography. They were managed by interventional procedures. All the other patients were doing well without symptoms, except one patients in Stage II who underwent PTCA procedure for a lesion in the circumflex artery during the follow up period. Conclusion: The new and specialized devices are essential to the development of MIDCAB surgery. MIDCAB and the hybrid procedures in multi-vessel disease are on the way to further development. So far, our experience is limited only to a single device among the many new devices for the purpose.

Background: Scalp seborrheic dermatitis is a common disease characterized by flaking and itching of the scalp. Conventional treatment options, such as the use of topical corticosteroids and antifungal agents, may cause adverse effects and reduce user satisfaction rates; thus, it is important to explore other treatment options for scalp seborrheic dermatitis. Objective: We aimed to evaluate the efficacy and safety of a new-formula shampoo containing natural ingredients, including the extract of Rosa centifolia petals, epigallocatechin gallate, zinc pyrithione, and climbazole. Methods: A total of 50 patients with scalp seborrheic dermatitis were enrolled and divided into two groups: the new-formula shampoo-treated group and the 1.5% ciclopirox olamine shampoo-treated group. Clinical severity scores, sebum secretion, and inflammatory cytokines were assessed. In addition, patient satisfaction and adverse events were assessed using a questionnaire. Results: The new-formula shampoo was comparable with ciclopirox in reducing the clinical severity scores and sebum secretion. Patients' improvement scores and user satisfaction rates were higher in the new-formula shampoo group than in the 1.5% ciclopirox olamine shampoo-treated group. The inflammatory cytokine levels considerably changed in both groups during the course of the study. Conclusion: Thus, the new-formula shampoo can be considered a treatment option for patients with scalp seborrheic dermatitis.

BACKGROUND : The purpose of this study was to investigate the new effective oriental medical treatments in pediatric diseases and its clinical applicability. METHOD : The study was composed of 1725 new patients who had been treated at the pediatric unit in the Dongguk Bun-Dang Oriental Medicine Hospital for 1 year, from 1 January 1997 to 31 December 1997, and had ages between 0 and 18 years. The chief complaint was mainly categorized by oral examination on patients and their care-givers. RESULT 1. The ratio of male to female was 1.35:1 and the number of each age group and its percentage distribution was 228 patients (13.2%) for the age group between 0 and 1 year, 746 patients (43.2%) between 2 and 6 years, and 751 patients (43.6%) for the age group over 7 years. 2. The chief complaint of the new outpatients was weakness, asthma, common cold, sinustis, skeletal disease, atopic dermatitis, stomach-ache, short stature, diarrhea, nasal blooding, night terror, allergic rhinitis, gastric disorder, enuresis, dermatitis, strabismus in the order of majority.3. The number of patients and its percentage for the most three complaints was 494 patients (28.6%) for weakness, 647 patients (37.4%) for respiratory disease, 144 patients (8.3%) for digestive disease. 4. The digestive disease tended to increase in summer, and appeared mostly in the age group between 0 and 2 years. The respiratory disease increased In inter-season and winter, but decreased significantly in summer. The age group between 1 and 5 years was the largest group of respiratory disease. CONCLUSION 1. The chief complaint in pediatric diseases that needed an oriental medical treatment was mainly the disease that tends to take long time and the weakness, and appeared frequently in digestive and respiratory diseases. 2. The oriental medical treatment was still preferred as a way to improve the weakness by patients, rather than a way to overcome their disease. In particular, the study shows that the oriental medical treatment should be emphasized in terms of preventing the disease. 3. The new diseases, which were developed with the change of human life and environment, (atopic dermatitis, enuresis, short stature, obesity, dysthymic disorder, strabismus), should be investigated as a new field of oriental medical treatment.

During a 17-month period 32 consecutive patients underwent coronary artery bypass graft. The mean age of these patients was 45.3 years [range 39 to 71 years]. There were 18 men and 14 women. Preoperatively 11 patients had stable angina pectoris and 12 patients of unstable angina pectoris. 28% [9 patients] had of myocardial infarction history. The patterns of disease were single vessel involvement [4 casis], double vessel involvement [11 cases], triple vessel involvement [12 caese] and 5 cases of left main coronary artery disease. Thirty-seven percent [12/32] were in New York Heart Association class IV. Myocardial revascularization was performed under emergency conditions in 3 patients. We performed 13 case of double anastomosis, 12 case of triple anastomosis and 4 case of 4 anstomosis [mean 2.59 anastomosis per patient]. The left internal mammary artery was used in 68.7%. 90% of the patients receieved two or more grafts. Complications occurred in 8 patients [25%]. All patients were followed up for a mean of 8.6 months [2 to 17 months]. There was no hospital and late death. Postoperatively 87% were in New York Heart Association class I or II and 96% of the patient were free from angina.

Objective : We compared the survival time between patients with multiple gamma knife radiosurgery (GKRS) and patients with a single GKRS plus whole brain radiation therapy (WBRT), in patients with multiple metachronous brain metastases from lung cancer. Methods : From May 2006 to July 2010, we analyzed 31 patients out of 112 patients who showed multiple metachronous brain metastases. 20 out of 31 patients underwent multiple GKRS (group A) and 11 patients underwent a single GKRS plus WBRT (group B). We compared the survival time between group A and B. Kaplan-Meier method and Cox proportional hazards were used to analyze relationship between survival and 1) the number of lesions in each patient, 2) the average volume of lesions in each patient, 3) the number of repeated GKRS, and 4) the interval of development of new lesions, respectively. Results : Median survival time was 18 months (range 6-50 months) in group A and 6 months (range 3-18 months) in group B. Only the average volume of individual lesion (over 10 cc) was negatively related with survival time according to Kaplan-Meier method. Cox-proportional hazard ratio of each variable was 1.1559 for the number of lesions, 1.0005 for the average volume of lesions, 0.0894 for the numbers of repeated GKRS, and 0.5970 for the interval of development of new lesions. Conclusion : This study showed extended survival time in group A compared with group B. Our result supports that multiple GKRS is of value in extending the survival time in patients with multiple metachronous brain metastases, and that the number of the lesions and the frequency of development of new lesions are not an obstacle in treating patients with GKRS.

Purpose: The 7th AJCC tumor node metastasis (TNM) staging system modified the classification of the lymph node metastasis widely compared to the 6th edition. To evaluate the prognostic predictability of the new TNM staging system, we analyzed the survival rate of the gastric cancer patients assessed by the 7th staging system. Materials and Methods: Among 2,083 patients who underwent resection for gastric cancer at the department of surgery, Hanyang Medical Center from July 1992 to December 2009, This study retrospectively reviewed 5-year survival rate (5YSR) of 624 patients (TanyN3M0: 464 patients, TanyNanyM1: 160 patients) focusing on the number of metastatic lymph node and distant metastasis. We evaluated the applicability of the new staging system. Results: There were no significant differences in 5YSR between stage IIIC with more than 29 metastatic lymph nodes and stage IV (P=0.053). No significant differences were observed between stage IIIB with more than 28 metastatic lymph nodes and stage IV (P=0.093). Distinct survival differences were present between patients who were categorized as TanyN3M0 with 7 to 32 metastatic lymph nodes and stage IV. But patients with more than 33 metastatic lymph nodes did not show any significant differences compared to stage IV (P=0.055). Among patients with TanyN3M0, statistical significances were seen between patients with 7 to 30 metastatic lymph nodes and those with more than 31 metastatic lymph nodes. Conclusions: In the new staging system, modifications of N classification is mandatory to improve prognostic prediction. Further study involving a greater number of cases is required to demonstrate the most appropriate cutoffs for N classification.

Objective: To find a more appropriate alternative to D-dimer cutoff value for the diagnosis of deep vein thrombosis (DVT) in cancer patients. Methods: A total of 711 cancer patients with symptoms suspicious of DVT were included in the study. D-dimer levels were assessed using ELISA. All patients were subjected to imaging procedures. Results: Among 711 patients with cancer, 466 (65.5%) were females and 245 (34.5%) were males, with an average age of $57.3{\pm}13.23$ years. The mean age in the DVT group was significantly higher than in the non-DVT group (P<0.05). The D-dimer levels of the DVT group were significantly higher than those of the non-DVT group (P<0.05). The incidence rate of DVT varied significantly according to cancer type (P<0.05). Increasing age and lung cancer were significantly correlated with D-dimer levels (P<0.05), and a one-year increase in age was associated with a 14.28 ng/ml increase in the D-dimer value. The optimal cutoff point for D-dimer was found to be 981 ng/ml, with a sensitivity of 86.4%, specificity of 79.4%, and accuracy of 82.6%. If the D-dimer cutoff point was set to 981ng/ml, the specificity would increase from 61.8% to 85.5% without loss of sensitivity in patients aged 40 years or younger. In patients aged more than 40 years, the new cutoff almost doubled the specificity with slightly reduced sensitivity. Conclusion: In cancer patients, a new cutoff value of 981 ng/ml effectively improved the exclusion of DVT, especially for patients aged more than 40 years.

Background This study evaluated the outcomes of a new modified Wies technique for patients with involutional lower eyelid entropion without horizontal eyelid laxity. Methods This case series retrospectively analyzed consecutive patients with entropion who underwent surgery between January 2014 and March 2019 by the same experienced surgeon. Horizontal eyelid laxity, lower eyelid retractor function, and orbicularis muscle overriding were recorded before and after surgery. The recurrence rate and complications were also evaluated. This technique consisted of modified everting sutures combined with reattachment of the lower eyelid retractors to the inferior tarsal plate. Results This new technique was performed on 28 eyes in 25 patients (mean age, 71.0±8.0 years; range, 56-87 years). Nine patients (36%) were women and 16 (64%) were men. Lower lid entropion was present in the right eye in 14 patients (56%), the left eye in eight patients (32%), and both eyes in three patients (12%). The mean follow-up period was 27.3±12.4 months (range, 6-60 months). No intraoperative complications were observed. All patients' symptoms were alleviated. One patient (3.6%) had recurrence after 2 years (success rate, 96.4%). The remaining 27 eyes maintained a satisfactory and comfortable eyelid position. No patients had problems with scarring. Conclusions The approach described herein proved to be safe and feasible in eyes with involutional lower eyelid entropion without horizontal eyelid laxity. These advantages of this procedure include the lack of a conjunctival scar, punctal eversion, and lateral canthal angle deformation. A low recurrence rate and a long interval to recurrence were also observed.
