SETTING: Undergraduate training on tuberculosis at Istanbul Medical School. OBJECTIVE: To assess whether tuberculosis-related questions asked in chest medicine examinations comply with the World Health Organization's (WHO) learning objectives for tuberculosis training, and to investigate students' skills in interpreting radiology and smears with respect to tuberculosis. DESIGN: Tuberculosis questions set for 4th year medical students (n = 838) were compared with WHO objectives (n = 23): 122 students were each asked to interpret 10 chest X-rays which had been read by three experts as 'typical tuberculosis lesions', 'normal' or 'non-tuberculosis lesions'; 114 students were also each given five smears which had been interpreted by an expert as 'negative' or 'positive' with respect to acid-fast-bacilli (AFB), and were asked to interpret them. RESULTS: Questions covered only nine of the WHO objectives. Among 117 types of questions, 91 (77.8%) were about clinical-radiological findings, treatment and drugs; 334 (65.1%) of 513 X-rays with typical tuberculosis lesions, 77 (21.1%) of 364 normal X-rays and 87 (25.4%) of 343 X-rays with non-tuberculosis lesions were identified as tuberculosis (kappa 0.45). Of 369 AFB-positive smears, 149 (40.4%) were evaluated as false negative, and of 185 AFB-negative smears, 48 (25.9%) were evaluated as false positive (kappa 0.49). CONCLUSION: Examination questions set on tuberculosis at Istanbul Medical School do not adequately reflect WHO learning objectives. Students' skills in interpreting radiology and smears suggest that their practical training on tuberculosis is insufficient. 相似文献

SETTING: Department of Chest Diseases, Istanbul Faculty of Medicine, Istanbul University. OBJECTIVE: To determine the clinical and radiographic presentation of pulmonary tuberculosis in non-AIDS immunocompromised patients (ICP). DESIGN: A retrospective review of medical records of 143 patients (63 immunocompromised patients and 80 immunocompetent patients) with pulmonary tuberculosis from 1992 to 2001. RESULTS: In ICPs, fever was more frequently observed (84.1% vs. 40%, P = 0.0000002), tuberculosis was more frequently disseminated (23.8 vs. 3.8%, P = 0.0008), and lung infiltrations were more often lobar or segmental consolidation (20.6% vs. 0%, P = 0.00007) and miliary lesions (17.5 vs. 3.8%, P = 0.014) than in the control patients. Hilar and/or mediastinal adenopathy was also more frequently documented in ICPs (14.3% vs. 2.5%, P = 0.01). CONCLUSION: Fever, atypical chest radiograph and disseminated disease are common findings of pulmonary tuberculosis in ICPs. 相似文献

Finding a gene or genes that are involved with multidrug resistance will be useful for finding a new target for the treatment of drug resistant tuberculosis. In this study, we aimed to compare the differences of the expression of 15 putative multidrug efflux pump genes in clinically isolated drug sensitive and multidrug resistant (MDR) Mycobacterium tuberculosis isolates, and reference strains. We found that these genes in the drug-sensitive and MDR M. tuberculosis isolates have similar rates of expressions. However, we found the expression levels of the all the genes are significantly higher in the clinical strains compared to the expression level of genes in the reference strains. In addition to this, it is found that standard strain has lower MIC value for the drugs including streptomycin and rifampin compared to the clinical isolate. We presume that the increase of the gene expression in the clinical strains is due to the exposure of antituberculosis drugs during treatment of patients, which cause constitutive expression of efflux systems, which might increase MIC levels of the major anti-tuberculosis drugs. 相似文献

Thoracic endometriosis is an uncommon disorder. In most cases, the diagnosis is based on history alone and radiographic findings depend on the menstrual cycle. CT findings include ill-defined or well-defined opacities, nodular lesions, cavities, cystic changes and bullous formation. We report a case of pulmonary parenchymal endometriosis with an unusual radiographic finding. 相似文献

A 2-mo-old infant with paramyotonia congenita was scheduled for pyloromyotomy and repair of inguinal hernia. Diagnosis of paramyotonia congenita was done with positive family history, myotonia at eyelids, provocation by cold, and electromyogram analysis. Anesthesia was induced via face mask with sevoflurane at 4 minimum alveolar anesthetic concentration in oxygen. Tracheal intubation was attempted without a neuromuscular relaxant. Anesthesia was maintained with sevoflurane at 0.5 minimum alveolar anesthetic concentration in oxygen and remifentanil infusion at a rate of 0.2 micro g. kg(-1). min(-1). After discontinuation of sevoflurane and remifentanil, the patient was awake and had full recovery of muscle activity. IMPLICATIONS: The literature concerning general anesthesia in paramyotonic patients is limited. We report a case of paramyotonia congenita in a 2-mo-old male infant undergoing surgery for pyloric stenosis and inguinal hernia after an uneventful anesthesia. 相似文献

Hereditary angioedema (HAE) is a rarely seen disorder of C1 inhibitor (C1-INH) deficiency usually manifested by non-pruritic swelling of the skin. Acute exacerbations are not sensitive to conventional medications, and C1-esterase inhibitor concentrates are recommended as the first-line therapy. However, fresh frozen plasma is the main treatment alternative in many centers due to the lack of C1-esterase inhibitor concentrates. In this report, we present 3 patients with acute exacerbations of hereditary angioedema who were effectively and safely treated with fresh frozen plasma. 相似文献

BACKGROUND: The aim of this study is to identify the effectiveness of perioperative pneumoperitoneum to prevent air leak after the lobectomy-bilobectomy operations for lung cancer. METHODS: A prospective study was designed on consecutive 50 patients who had lobectomy-bilobectomy operations for lung cancer and whose remnant lung had failed to fill the half of the hemithoracic cavity under 30 cm H(2)O positive pressure ventilation during the operation with totally relaxed diaphragm. The patients were divided into two groups: group 1 (25 patients) with perioperative pneumoperitoneum, group 2 (25 patients) without perioperative pneumoperitoneum. RESULTS: The statistical analysis between the two groups did not show any significant difference in terms of age, preoperative FEV1, and the type of resection. Perioperative pneumoperitoneum significantly reduced the duration of postoperative air leak (2.2 +/- 1.15 days vs. 6.04 +/- 3.27 days p < 0.0001) and total chest tube drainage time (3.84 +/- 0.98 days vs. 7.88 +/- 3.16 days p < 0.001). CONCLUSION: Perioperative pneumoperitoneum after lobectomy-bilobectomy operations for lung cancer is an effective method to decrease air leak and chest tube drainage time. 相似文献

Chylothorax is the most common cause of pleural effusion in the newborn. We report three patients with congenital chylothorax and discussed the clinical course and treatment options. Cases 1 and 2 with congenital chylothorax were treated by chest tube placement and total parenteral nutrition (TPN), and were fed a formula rich in medium-chain triglyceride. They were discharged home without any sequelae. Our 3rd case with chylothorax did not respond to the conventional therapies. Octreotide infusion was tried without any benefits and necessitated surgical intervention, but the infant developed chronic lung disease requiring nasal oxygen therapy until three months of age. All three patients developed complications of chylothorax treatment like chest tube dysfunction, pneumothorax, nosocomial sepsis, and cholestasis. Management of congenital chylothorax necessitates a multidisciplinary approach. Treatment options include pleural drainage, cessation of enteral feeding and initiation of TPN. Experience with octreotide treatment is limited. Surgery should be reserved for severe and refractory cases. 相似文献
