  • Background: A tuberculous destroyed lung is sequelae of pulmonary tuberculosis and causes various respiratory symptoms and pulmonary dysfunction. The patients with a tuberculous destroyed lung account for a significant portion of those with chronic lung disease in Korea. However, few reports can be found in the literature. We investigated the computed tomography (CT) findings in a tuberculous destroyed lung and the correlation with lung function. Methods: A retrospective analysis was carried out for 44 patients who were diagnosed with a tuberculous destroyed lung at the Keimyung University Dongsan Hospital between January 2004 and December 2009. Results: A chest CT scan showed various thoracic sequelae of tuberculosis. In lung parenchymal lesions, there were cicatrization atelectasis in 37 cases (84.1%) and emphysema in 13 cases. Bronchiectasis (n=39, 88.6%) was most commonly found in airway lesions. The mean number of destroyed bronchopulmonary segments was 7.7 (range, 4~14). The most common injured segment was the apicoposterior segment of the left upper lobe (n=36, 81.8%). In the pulmonary function test, obstructive ventilatory defects were observed in 31 cases (70.5%), followed by a mixed (n=7) and restrictive ventilatory defect (n=5). The number of destroyed bronchopulmonary segments showed a significant negative correlation with forced vital capacity (FVC), % predicted (r=-0.379, p=0.001) and forced expiratory volume in one second ($FEV_1$), % predicted (r=-0.349, p=0.020). After adjustment for age and smoking status (pack-years), the number of destroyed segments also showed a significant negative correlation with FVC, % predicted (B=-0.070, p=0.014) and $FEV_1$, % predicted (B=-0.050, p=0.022). Conclusion: Tuberculous destroyed lungs commonly showed obstructive ventilatory defects, possibly due to bronchiectasis and emphysema. There was negative correlation between the extent of destruction and lung function.

  • Background: The involvement of HPV in oral and oropharyngeal carcinogenesis was first proposed in 2004, based on epithelial HPV tropism and detection of HPV genotypes in oral squamous cell carcinoma samples. While 60-70% of oropharynx tumors may be HPV-positive, only 10 to 19% of tumors of the oral cavity, larynx and hypopharynx appear to have HPV infection. The aim of the study was to evaluate HPV infection associated with oropharyngeal cancer. Materials and Methods: Seventy-eight cases were selected for p16 immunoexpression reactions, and demographic data were collected for comparisons. Results: Most patients were over 60 years old, and 64.1% were smokers. Immunohistochemistry results showed that 86.3% of cases stained positive for p16 protein. Conclusion: The oropharyngeal cancer profile at Erasto Gaertner Hospital presented a high index of smokers over 60 years as well a high number of p16+ tumors, for what we can not determinate the main etiologic factor, but can be aware of the number of patients that presented HPV infection. Since prevention is still the best way to deal with cancer disease, it is important to analyze the interaction of these two etiologic factors and how to detect lesions at an early stage.

  • Ethanol exerts different effects on hepatic cellular metabolism, depending mainly on the duration of its intake. In the presence of ethanol following an acute load, a number of hepatic functions are inhibited, including lipid oxidation and microsomal drug metabolism. In its early stages, chronic ethanol consumption produces adaptive metabolic changes in the endoplasmic reticulum which result in increased metabolism of ethanol and drugs and accelerated lipoprotein production. Prolongation of ethanol intake may result in injurious hepatic lesions such as alcoholic hepatitis and cirrhosis A number of such metabolic effects of ethanol are directly linked to the two major products of its oxidation; hydrogen and acetaldehyde. The excess hydrogen from ethanol unbalances the liver cell's chemistry. In the presence of excess hydrogen ions the process is turned in a different direction. In this study, it was attempted to observe the effect of ginseng saponins on alcohol Oehydrogenase(ADH), aldehyde dehydrogenase(ALDH) and microsomal ethanol oxidizing system(MEOS) in vivo as well as in vitro. Furthermore, the effect of ginseng saponin on the hydrogen balance in the liver and the hepatic cellular distribution of (1-14C) ethanol, its incorporation into acetaldehyde and lipids was also investigated. It seemed that ginseng saponin stimulated the above enzymes and other related enzymes in ethanol metabolism, resulting in a rapid removal of acetaldehyde and excess hydrogen from the animal body,

  • Purpose: To determine the incidence of high-grade cervical intraepithelial neoplasia (CIN2-3) among patients with atypical squamous cells of undetermined significance (ASC-US) Papanicolaou (Pap) smears. Materials and Methods: One-hundred and eighty-seven patients with ASC-US Pap smears who underwent colposcopy with histological study were enrolled between September 2007 and August 2015. Patient factors (including age, parity, current pills used, HIV status, age at first sexual intercourse and number of sexual partners) were obtained. Logistic regression analysis was used to evaluate clinical factors associated with CIN2-3. Results: CIN was diagnosed in 92 of 187 women (49.2%). Sixty-one of these (32.6%) had CIN1 and 31 (16.6%) had CIN2-3. There was no woman who had invasive cancer. There was no correlation of high-grade CIN with factors in this study including age, parity, current pills used, HIV status, age at first sexual intercourse and number of sexual partners. Conclusions: Data from this study showed no invasive cervical cancer was found in patients with ASC-US. There was no patient factor associated with high grade intraepithelial neoplasia in patients with ASC-US Pap smears.

  • To prevent recurrence of spontaneous pneumothorax, 23 patients were operated through median sternotomy for simultaneous resection of bilateral bullae, And 27 patients with spontaneous pneumothorax were treated with unilateral thoracotomy, We studied the number, duration and sites of recurrence including findings of CT scan, as well as comparing the both operated group. The incidence of spontaneous pneumothorax was 88% in patients with the ages between 16 to 35 Forty one patients[82%] were operated with the indication of recurrent pne-umpthorax. The number of pneumothorax attack was 2.34 per patient with recurrent pneumothorax. The 87.8% of recurrence was occured within 6 months from last attack. Ips-ilateral recurrnet pneumothorax was 56.1% and contallateral involve was 43.9%. The bilaterality of visible bullae was 90.9% in the findings of chest CT scan and 91.3% in the operative finding. The sensitivity and accuracy for bulla detection with chest CT were 92.6%, respectively. Exclude one case of complicated median sternotomy infection, the postoperative hospital stay was shorter in median sternotomy approached group[P<0.05]. In conclusion, the bullous lesions of the lung have tendency of bilaterality so that median sternotomy for simultaneous resection of bilateral bullae should be considered in patients with contralateral visible bullae with chest CT.

  • The global number of Mycobacterium avium complex (MAC) pulmonary infection is increasing. Patients with preexisting lung disease or who are immunodeficient are at the greatest risk for developing MAC infection. Endobronchial lesions with MAC infection are rare in the immunocompetent host. However, there have been an increasing number of reports of an immunocompetent host being afflicted with various manifestations of MAC infection. We report a case of pulmonary and endobronchial MAC infection presenting as an acute pneumonia in a 59-year-old female without preexisting lung disease or immunodeficiency.

  • Objective : The sacroiliac joint complex is often related with functionally incapacitating pain in old aged people. The purpose of this study is to delineate the investigation strategies and to determine the long-term effect of radiofrequency [RF] neurotomies for pain arising from sacroiliac Joint dysfunction[SIJD]. Methods : Sixteen patients were diagnosed as having chronic pain from SIJD by comparative controlled blocks on L5 dorsal rami, sacroiliac Joints and deep interosseous ligaments. After confirming the positive response [more than 50% of pain relief], sensory stimulation was applied to detect the 'pathological' branches. Subsequently, RF neurotomies were performed on the selected nerve branches. Surgical outcome was graded as successful, moderate improvement, and failure after a 6month follow-up period. Results : Stimulation intensity was 0.45V to elicit pain response in the L5 dorsal rami and lateral sacral branches. The number of RF-lesioned nerve branches was 6per patient. The average number of lesions for each branch was 1.3. Most commonly selected branches were L5 dorsal ramus [88%] and S2-upper division [88%]. Ten patients [63%] reported a successful outcome according to the outcome criteria after 6months of follow-up, and five patients [31%] reported complete relief [100%]. Five patients [31%] showed moderate improvements. One patient reported failure. Conclusion : RF neurotomy of lateral sacral branches is an excellent treatment modality for the pain due to SIJD, provided that comparative controlled block shows a positive response.

  • A mosaic diseased radish collected from the suburb of Seoul, in November, 1961 was used for studing the host range, physical properteis, purificaitiion, insect transmission, and electron microscopy. A Japanese strain of radish mosaic(RPV) was also used with Korean strain of radish mosaic (KRMV) for a comparative study. The two viruses, KRMA and RPV, were identified by the difference in host range, insect transmission and electron microscopy. The KRMA was severely infective on tobacco and Nicotiana glutinosa, while on Gomphrena globsa was immune to the virus. RPV produces necrotic local lesions on Gomphrena globosa but did not infect tobacco and N. glutinosa. Among varieties of radish, Seoul, Akamaroo, Akanagea, Koong-Joong showed more severe symptoms than Simoo, Minong, Paek-soo, which appeared to be fainly resistant. In a number of tests, it was found that the virus KRMA retained its infectivity until to a dilution of 1:2,000, heating at $58^{\circ}$ for 10 minutes, adn aging in vitro for 7 days at room temperature. The RPV was not inactivated until it was diluted to 1:2,000, heated to $56^{\circ}$, and aged for 6 days. The KRMV was readily transmitted by the aphid(Myzus persicae Sulz). The virus RPV was not transmitted by the aphid in a number of tests. Partialy purified viruses using ammonium acetate buffer, salting-out by ammonium sulfate and centrifugation of high and low speed were highly infective. Electron micrographs showed that the KRMV paticles are of spherical particles whereas the RPV particles are rod-shaped.

  • HHPV (Human Papillomavirus) is a DNA virus that can cause benign lesions, genitourinary cancer, and oropharyngeal cancer by penetrating the mucous membrane and skin. It is widely known to be transmitted mainly through sexual contact. As with many viral infections, vaccines have been developed to prevent infection with HPV. Currently, in many countries, HPV vaccines are mainly used for national immunization for women to prevent diseases that traditionally occur frequently in women, especially cervical cancer. However, since the vaccination rate is relatively low, many countries are struggling with ways to increase the vaccination rate. Meanwhile, the incidence of oropharyngeal cancer caused by HPV in men has been increasing recently. In the United States, the annual number of oropharyngeal cancers in men already exceeds the number of cervical cancers in women, so HPV infection in men has emerged as a major problem. Accordingly, interest in HPV vaccination in men has also increased, and studies on the effectiveness and necessity of vaccination of both women and men compared to women alone are being actively conducted. In this paper, the evidence of HPV vaccination for men will be reviewed through previous studies, and its validity and cost-effectiveness will be analyzed to bolster the clinical usefulness of HPV vaccination for men.
