Background: The treatment success rates in patients with tuberculosis are known to be lower in the private sector compared to the public sector. To improve treatment outcomes in the private sector we developed a public-private collaboration model for strengthening health education and case holding activities with public health nursing in the private sector. Methods: We performed a prospective cohort study in new smear positive pulmonary tuberculosis patients treated at private hospitals, selected by non-randomization, with an intervention consisting of health education and case holding activities by specially trained public health nurses (intervention group) results were compared with cases treated without the intervention (conventional group). Physicians were asked to treat both groups routinely. The treatment outcomes of patients under treatment by the National Tuberculosis Programme were also analyzed for comparison. Results: There were 172 cases each in the intervention and conventional groups. The mean age was 48.9±19.0 and 48.2±19.7 in the respective groups (p=0.66). The PHN interacted with the cases in the intervention group by initial face to face interview and telephone calls an average of 7.1±9.2 times during the initial six months. The intervention group showed a significantly higher treatment success rate, 91.6%, (Rate Ratio [RR]; 1.23, 95% Confidence Interval [CI]; 1.12∼1.36), lower default, 3.6%, (RR; 0.31, 95% CI; 0.13∼0.75) and transfer-out rate, 3.0%, (RR; 0.32, 95% CI; 0.12∼0.86) than the conventional group where they were: 75.0%, 11.6%, 9.3%, respectively. The success rate was even higher than the rate (80.5%) of 1,027 cases treated in health centers (RR; 1.11, 95% CI; 1.05∼1.17). Of the completed cases in the intervention group, 82.2% regarded the role of the public health nurse as very helpful. Conclusion: The treatment success rate, of tuberculosis patients in the private sector, was significantly improved by an intervention using a public-private collaboration model.
Background: The appropriate empirical antimicrobial choice in the treatment of community-acquired pneumonia(CAP) should be advocated by community-based information on the etiologic pathogens, their susceptibility to antimicrobials, clinical characteristics and outcomes. Jeju is a geographically isolated and identical region in Korea. However, there is no regional reference on adult CAP available. This study investigated the etiologic agents and clinical outcomes of adult patients diagnosed with CAP in Jeju, Korea, to help guide the empirical antimicrobial choice. Methods: A prospective observational study for one year in a referral hospital in Jeju, Korea. Patients diagnosed with CAP were enrolled with their clinical characteristics. Microbiological evaluations to identify the etiologic agents in the adult patients with CAP were performed with blood culture, expectorated sputum smear and culture, antibody tests for mycoplasma, chlamydophila, and antigen tests for legionella and pneumococcus. The clinical outcomes of the initial empirical treatment were analyzed. Results: Two hundred and three patients with mean age of 64 and 79 females were enrolled. Ten microbials from 90 cases (44.3%) were isolated and multiple isolates were confirmed in 30. Among the microbial isolates, S. pneumoniae (36.3%) was the most common, followed by M. pneumoniae (23.0%), C. pneumoniae (17.0%), S.aureus (9.6%) and P. aeruginosa (5.9%). The initial treatment failure (23.8%) was related to the isolation of polymicrobial pathogens, elevated inflammatory markers, and the presence of pleural effusion. Among the 30 isolates of S. pneumoniae, 16 (53.3%) were not susceptible to penicillin, and 19 isolates (63.3%) to erythromycin and clarithromycin. However, 29 isolates (96.7%) were susceptible to levofloxacin and ceftriaxone. Conclusion: S. pneumoniae, M. pneumoniae, S. aureus, and P. aeruginosa are frequent etiologic agents of adult CAP in Jeju, Korea. The clinical characteristics and antibiotic resistance should be considered when determining the initial empirical antimicrobial choice. Respiratory quinolone or ceftriaxone is recommended as an empirical antimicrobiotic in the treatment of adult CAP in Jeju, Korea.
Prompt and proper discovery of cause is important in lung cancer patients with signs and symptoms of intestinal obstruction because approach for treatment may differ according to its etiology and emergency operation can often be required to prevent more severe complications. In this report, we present two different causes of intestinal obstruction in lung cancer. Physicians need to be aware of these possibilities to differentiate the cause of intestinal obstruction in patients with lung cancer.
Crohn’s disease, a major form of inflammatory bowel disease (IBD), is a chronic inflammatory condition that is characterized by microvascular and macrovascular involvement. Some extraintestinal complications can occur due to chronic systemic inflammation in IBD. Among them, a pulmonary hromboembolism is a rare manifestation of IBD but is associated with a high morbidity and mortality. To our best of knowledge, there is only one case report of a pulmonary thromboembolism as a complication of Crohn’s disease in Korea. We present another rare case of pulmonary thromboembolism as complication in a 25-year-old man with underlying Crohn’s disease.
천식조절 중이던 환자에서 임상증상과 조직검사를 바탕으로 진단된 Churg-Strauss 증후군을 진단하고 치료 중발생한 장천공을 경험하였기에 문헌고찰과 함께 보고하는 바이다.
Churg-Strauss syndrome (CSS) or allergic granulomatous angiitis is a rare syndrome that is characterized by hypereosinophilic systemic necrotizing vasculitis affecting small- to medium-sized arteries and veins. In general, it occurs in individuals with pre-existing allergic asthma. When CSS appears in patients, it has the following characteristics: eosinophilia of more than 10% in peripheral blood, paranasal sinusitis, pulmonary infiltrates, histological proof of vasculitis with extravascular eosinophils, and mononeuritis multiplex or polyneuropathy. Therapeutic trials dedicated to Churg-Strauss syndrome have been limited due to the rarity of this disorder and the difficulty in making a histological diagnosis. Proper treatment of patients with CSS is not widely known. In this case study, we report on our experience with an unusual patient case, characterized by purpura and a perforation of the small intestine after inadequate steroid therapy.
Drug-induced subacute cutaneous lupus erythematosus (SCLE) is associated with use of the following classes of medications: anti-hypertensives, anti-cholesterolemia, anti-psychotics, and anti-inflammatory drugs. Docetaxel is an anti-neoplastic agent, which is widely used for treatment of non-small cell lung cancer. Few cases of docetaxel-induced SCLE have been reported in the medical literature. Here, we report the case of a 58-year-old female patient who developed drug-induced SCLE after administration of docetaxel. After 4 cycles of chemotherapy with docetaxel and cisplatin, erythematous skin eruptions developed on the patient’s face. Skin biopsies of the eruptions were remarkable for interfacing dermatitis with basement membrane thickening. Immunofluorescent study revealed characteristic features of SCLE, including granular deposition of IgM, C3, and apoptotic bodies along the basement membrane. The skin eruptions resolved gradually after cessation of drug and with the use of topical corticosteroids.
Congenital cystic adenomatoid malformation (CCAM), which is classified into five types according to size and bronchial invasion, is a rare type of developmental anomaly of the lung. CCAM is occasionally accompanied by malignancy, such as bronchioloalveolar carcinoma (BAC) or habdomyosarcoma. As defined by the WHO, atypical adenomatous hyperplasia (AAH) is a non-invasive spread of atypical epithelial cells in single rows along the alveolar wall, within a lesion that is usually less than 5 mm in diameter. AAH was also regarded as a pre-invasive neoplasia, especially associated with BAC and adenocarcinoma. We report a case of type II CCAM with AAH in adults, with a review of the references.
기관지폐쇄에 의한 폐농양 혹은 공동성 병변에 발생한암성 농양은 임상 양상 및 방사선학적 소견이 흡인성 폐농양과 흡사하여 감별이 어려워서 폐암을 조기 진단할 수있는 기회를 놓치기 쉽다. 따라서 항생제에 대한 반응이뚜렷하지 않거나 선행 요인이 없고 비전형적인 위치에 발생한 폐농양의 경우 악성 병변의 동반 가능성을 염두에두고 적극적인 검사가 필요하다. 저자들은 발열, 기침, 혈담, 호흡곤란을 주소로 내원하여 폐농양 의심하에 항생제치료에도 불구하고 병변이 악화된 67세 남자 환자에서 간세침흡인생검을 통해 다발 전이성 농양을 일으킨 편평상피세포암성 농양으로 진단된 예가 있어 문헌 고찰과 함께보고하는 바이다.
Among the bronchogenic carcinomas, especially squamous cell carcinoma and large cell carcinoma frequently present with cavitation, which may result from tumor necrosis. Cavitary lesions of the tumor are occasionally associated with infection and misdiagnosed as benign lung abscess owing to the partial responsiveness to antibiotics. It is very difficult to distinguish the carcinomatous abscess from the benign lung abscess, because of their similar clinical and radiologic features. Delay in diagnosis of underlying lung cancer may result in poor outcome. Therefore, clinicians should remember that the patients with highly suspicious carcinoma of the lung should undergo further precise examinations to find out malignant cells.
