STUDY OBJECTIVE: Paragonimiasis is a typical food-borne parasitic disease that is common in Southeast Asia, the Far East, Latin American, and Africa. Recently, however, this disease has been seen in many parts of the world, largely due to increases in the numbers of immigrants and overseas travelers. The purpose of this study was to evaluate the clinical and radiologic features of recently diagnosed pulmonary paragonimiasis. PATIENTS: We retrospectively analyzed the clinical and radiologic characteristics of 36 patients (21 men and 15 women; median age 48 years; range, 19 to 75) with pulmonary paragonimiasis whose conditions were diagnosed between October 1994 and September 2004. RESULTS: Thirty-four patients (94%) presented with respiratory symptoms, including hemoptysis (n = 20, 56%) and cough (n = 17, 47%). However, chest pain (n = 5, 14%) and fever (n = 5, 14%) were less frequently reported. Chest radiography revealed intrapulmonary parenchymal lesions (n = 26, 72%), such as nodules (n = 14, 39%), linear opacity (n = 6, 17%), and airspace consolidations (n = 4, 11%), which occurred more commonly than did pleural lesions (n = 10, 28%). Most cases were initially suspected to be lung cancer or tuberculosis. In 13 patients with intrapulmonary parenchymal lesions who underwent bronchoscopy, bronchial luminal narrowing, coupled with congested or edematous mucosal changes, was seen in 7 patients (54%). Bronchial mucosal biopsy specimens exhibited chronic inflammation with eosinophilic infiltrations in three of these seven patients (43%). CONCLUSIONS: Our findings indicate that patients with pulmonary paragonimiasis presented with a variety of clinical and radiologic findings that were different from the classic presentations reported earlier, frequently mimicking those of lung cancer or tuberculosis. 相似文献

An enzyme immunoassay kit that detects serum IgA antibody reacting to glycopeptidolipid core antigen derived from Mycobacterium avium complex (MAC) was not useful for differentiating MAC pulmonary disease (PD) from Mycobacterium abscessus complex PD (MAB-PD). However, this assay could be useful for differentiating MAC- and MAB-PD from pulmonary tuberculosis. (This study has been registered at ClinicalTrials.gov under registration no. .) NCT00970801相似文献

We investigated the effects of rifampin and rifabutin on serum itraconazole levels in patients with chronic pulmonary aspergillosis. Serum itraconazole concentrations were significantly lower in patients who received itraconazole with rifampin (median, 0.1 μg/ml; P < 0.001) or rifabutin (median, 0.34 μg/ml; P < 0.001) than those receiving itraconazole alone (median, 5.92 μg/ml). Concomitant use of rifampin or rifabutin and itraconazole should be avoided in patients with chronic pulmonary aspergillosis and coexisting mycobacterial infections. 相似文献

BackgroundVancomycin is the treatment of choice for serious methicillin-resistant Staphylococcus aureus (MRSA) infections. Current guidelines recommend giving an initial loading dose (LD) of 25–30 mg/kg to rapidly increase the serum concentration. However, high-quality evidence for the clinical benefit of LD is lacking. Herein, we aim to examine the association between vancomycin LD and clinical outcome.MethodsA retrospective cohort study was conducted on adult patients treated for MRSA pneumonia with vancomycin in medical intensive care units from April 2016 to August 2018. MRSA pneumonia was defined by the Centers for Disease Control and National Healthcare Safety Network definition. The primary outcome was the clinical cure of pneumonia. Secondary outcome measures included time to pharmacokinetic (PK) target attainment, microbiological cure, acute kidney injury, and all-cause mortality.ResultsA total of 81 patients were included; of these 22 (27.2%) received LD. The mean initial dose was significantly higher in the LD group. Clinical cure was similar in both groups (68.2% vs. 66.1% in the LD and non-LD groups, respectively; P=0.860). No significant difference was observed in the microbiological cure, all-cause mortality, and incidence of acute kidney injury. Furthermore, no difference was observed in terms of time to PK target attainment (69.2 vs. 63.4 h in the LD and non-LD groups, respectively; P=0.624). Vancomycin minimum inhibitory concentration of <2 mg/L was identified as an independent predictive factor for clinical cure in multivariable analysis, whereas vancomycin LD was not.ConclusionsInitial LD is not associated with better clinical outcome or rapid pharmacological target attainment in critically ill patients with MRSA pneumonia. Further studies are warranted to provide better evidence for this widely recommended practice. 相似文献

OBJECTIVE: The purpose of our study was to identify any specific CT features that may help in the diagnosis of pleuropulmonary paragonimiasis. CONCLUSION: Pleuropulmonary paragonimiasis usually manifests as a subpleural or subfissural nodule of about 2 cm in diameter that frequently contains a necrotic low-attenuation area. The constellation of focal pleural thickening and subpleural linear opacities leading to a necrotic peripheral pulmonary nodule is another frequent CT finding of paragonimiasis. Although minimal and easily overlooked, focal fibrotic pleural thickening adjacent to a pulmonary nodule can be an important clue in the diagnosis of pleuropulmonary paragonimiasis on CT. 相似文献

Background and objective: Bronchoscopic resection of endobronchial hamartomas has been reported to have a favourable outcome. This study describes the bronchoscopic features of endobronchial hamartoma and reports the clinical outcome of bronchoscopic intervention. Methods: A retrospective analysis was conducted of patients with histologically proven endobronchial hamartomas, diagnosed in the 10‐year period 1999–2009 to elucidate the clinical, radiological and bronchoscopic features of hamartoma and to describe the clinical outcomes. Results: Seventeen of the 135 patients with pulmonary hamartomas were diagnosed as having endobronchial hamartomas. CXR was abnormal in 11 of the 17 patients. On chest CT (n = 16), the median diameter of the lesion was 15.6 mm. Calcification and areas of focal fat in the lesion, the diagnostic CT findings of pulmonary hamartoma, were found in two of 16 (12.5%) patients. At bronchoscopy (n = 16), all tumours had a mass appearance and most were smooth surfaced round masses (50.0%) with 18.8% having a ‘stalk’. Bronchoscopic forceps biopsies were performed in 13 patients, which resulted in five patients (38.5%) being diagnosed with endobronchial hamartoma. Fifteen patients were treated with rigid or flexible bronchoscopic resection, one had lobectomy, and one had no intervention. No procedure‐related mortalities or late complications developed. Conclusions: Bronchoscopic intervention appears to be a safe and effective method to resect endobronchial hamartomas. 相似文献

Introduction and objectives
This study investigated whether the vasoactive inotropic score (VIS) is independently predictive of mortality in cardiogenic shock (CS).Methods
This study was retrospective, observational study. Patients who were admitted to the cardiac intensive care unit from January 2012 to December 2015 were screened, and 493 CS patients were finally enrolled. To quantify pharmacologic support, the patients were divided into 5 groups based on a quintile of VIS: 1 to 10, 11 to 20, 21 to 38, 39 to 85, and > 85. The primary outcome was in-hospital mortality.Results
In-hospital mortalities in the 5 VIS groups in increasing order were 8.2%, 14.1%, 21.1%, 32.0%, and 65.7%, respectively (P < .001). Multivariable analysis indicated that VIS ranges of 39 to 85 (aOR, 3.85; 95%CI, 1.60-9.22; P = .003) and over 85 (aOR, 10.83; 95%CI, 4.43-26.43; P < .001) remained significant prognostic predictors for in-hospital mortality. With multiple logistic regression to remove any confounding effects, we found that the localized regression lines regarding the odds of death intersected each other's (medical therapy alone and combined extracorporeal membrane oxygenation group) path at VIS = 130. In contrast to linear correlation between VIS and mortality for patients treated with medical therapy alone, there was little association between a VIS of 130 or more and the probability of in-hospital mortality for patients who were treated with extracorporeal membrane oxygenation.Conclusions
A high level of vasoactive inotropic support during the first 48 hours was significantly associated with increased in-hospital mortality in adult CS patients. 相似文献9.

Objective
We investigated low dose digital tomosynthesis (DT) for the evaluation of the paranasal sinus (PNS), and compared its diagnostic accuracy with a PNS radiography series (XR).Materials and Methods
We enrolled 43 patients for whom XR, PNS DT, and OMU CT were performed. We measured effective doses (EDs) of XR, DT, and OMU CT using Monte Carlo simulation software. Two radiologists performed independent observation of both XR and DT. For seven PNSs, they scored anatomic conspicuity of sinuses and confidence on the presence of sinusitis using nine point scales. OMU CT was observed by the third radiologist and the findings were regarded as reference standard. We compared scores for conspicuity and sinusitis confidence between XR and DT.Results
Mean EDs were 29 ± 6 µSv, 48 ± 10 µSv, and 980 ± 250 µSv, respectively, for XR, DT, and CT. Mean scores for conspicuity were 6.3 and 7.4, respectively, for XR and DT. Sensitivity per patient basis for sinusitis detection were 52% and 96%, respectively, for XR and DT in observer 1 (p = 0.001) and 80% and 92% for observer 2 (p = 0.25). Specificities for sinusitis exclusion were 100% for both XR and DT for observer 1 and 89% and 100% for observer 2 (p = 0.50). Accuracies for sinusitis diagnosis were 72% and 98%, respectively, for XR and DT for observer 1 (p = 0.001) and 84% and 95% for observer 2 (p = 0.125).Conclusion
Patient radiation dose from low dose DT is comparable with that of PNS XR. Diagnostic sensitivity of DT for sinusitis was superior to PNS XR. 相似文献10.
