Bronchogenic carcinoma, the commonest lung tumor occurs more frequently in the elderly with typical symptoms of cough, haemoptysis, weight loss, dyspnoea or chest pain. These symptoms mimic common respiratory infections in en-demic areas like pulmonary tuberculosis. Also, metastasis at presentation itself is common, the favoured sites being liver, contra-lateral lungs, bones, brain, etc., although unusual and rare sites like heart also are known. We herein report a rare association of both carcinoma with active pulmonary tuberculosis in the same lobe associated with intracardiac metastasis. Very few cases have been published describing lung carcinoma with intracardiac metastasis. We hope the documentation of this rare case will shed further light into the subject area and improve clinical education. 相似文献

Background Bisphosphonate use in adult patients has been linked to osteonecrosis of the jaw (ONJ). This complication has not been systematically assessed in a paediatric population receiving bisphosphonates.
Objective To assess our cohort of paediatric patients treated with intravenous bisphosphonate for occurrence of ONJ.
Design Observational study at a tertiary children's hospital.
Patients A total of 42 paediatric patients with osteoporosis who received bisphosphonate infusions for a mean of 6·5 years (SD 2·7 years) were assessed clinically and radiographically for possible ONJ. Among 42, 37 patients had received disodium pamidronate 1 mg/kg/dose at a mean cumulative dose of 19·8 mg/kg and zoledronic acid (ZA) 0·05 mg/kg/dose at a mean cumulative dose of 0·49 mg/kg; four had received ZA and one received pamidronate alone. Invasive dental treatment during bisphosphonate treatment, a known risk factor for osteonecrosis, was specifically assessed.
Results In all patients assessed, including 11 who had invasive dental treatment, there were no cases of osteonecrosis.
Conclusion ONJ has so far not been demonstrated in this patient group. 相似文献

Though a century old hypothesis, infection as a cause for atherosclerosis is still a debatable issue. Epidemiological and clinical studies had shown a possible association but inhomogeneity in the study population and study methods along with potential confounders have yielded conflicting results. Infection triggers a chronic inflammatory state which along with other mechanisms such as dyslipidemia, hyper-homocysteinemia, hypercoagulability, impaired glucose metabolism and endothelial dysfunction, contribute in pathogenesis of atherosclerosis. Studies have shown a positive relations between Cytotoxic associated gene-A positive strains of Helicobacter pylori and vascular diseases such as coronary artery disease and stroke. Infection mediated genetic modulation is a new emerging theory in this regard. Further large scale studies on infection and atherosclerosis focusing on multiple pathogenetic mechanisms may help in refining our knowledge in this aspect. 相似文献

Background
The significance of tumor markers in patients with appendiceal carcinomatosis is poorly defined. We determined preoperative and postoperative tumor marker levels in patients undergoing cytoreductive surgery (CRS) and heated intraperitoneal chemoperfusion (HIPEC) and examined their association with clinicopathologic features and survival.Methods
A total of 176 patients undergoing attempted CRS/HIPEC for appendiceal carcinomatosis had at least 1 tumor marker measured. Marker levels were correlated with tumor characteristics and oncologic outcomes. Kaplan–Meier curves and multivariate Cox regression models were used to identify prognostic factors affecting progression and survival.Results
At least 1 marker was elevated prior to CRS/HIPEC in 70 % of patients (CEA, 54.1 %; CA19-9, 47.7 %; CA-125, 47.2 %). Among patients with elevated preoperative marker levels, normalization occurred postoperatively in 79.4 % for CEA, 92.3 % for CA19-9, and 60 % for CA-125. Absolute preoperative tumor marker levels correlated with peritoneal carcinomatosis index (PCI) (p < .0002), and the number of elevated markers was associated with PCI and progression-free survival (PFS). Elevated postoperative CEA level was associated with decreased PFS (median, 13 vs 36 months, p = .0008). On multivariate Cox regression analysis, elevated preoperative CA19-9 was associated with shorter PFS (hazard ratio [HR] 2.9, 95 % confidence interval [95 % CI] 1.5–5.3, p = .0008), whereas elevated CA-125 was associated with shorter overall survival (HR 2.6, 95 % CI 1.3–5.4, p = .01).Conclusions
Most patients with appendiceal carcinomatosis will have at least 1 elevated tumor marker and will normalize following CRS/HIPEC, allowing for ongoing surveillance. CA19-9 is a promising biomarker for early progression following CRS/HIPEC, whereas CA-125 is associated with shorter survival. 相似文献47.

Purpose Capecitabine in combination with docetaxel given every 3 weeks has shown a high degree of activity in a number of tumor types, but at the expense of significant toxicity. To improve the therapeutic index, we evaluated a weekly regimen of docetaxel in combination with capecitabine, and determined the maximum tolerated dose, toxicities and pharmacokinetics of this combination.Patients and methods Patients with advanced solid malignancies were treated with docetaxel on days 1 and 8, and capecitabine, twice daily on days 1–14, of an every-21-day cycle. Pharmacokinetics of docetaxel were assessed on days 1 and 8 of the first cycle of chemotherapy.Results Enrolled in the study were 25 patients. The most frequent toxicities were asthenia, hand-foot syndrome and mucositis. Inability to deliver at least 75% of the planned doses of both drugs during the first two cycles of chemotherapy was noted at dose levels 2, 3 and 4. Dose level 1 (docetaxel 30 mg/m2 and capecitabine 825 mg/m2 twice daily) is the recommended dose for phase II studies. Five patients experienced a partial response, and eight patients had stabilization of disease. Coadministration of capecitabine did not alter the pharmacokinetics of docetaxel.Conclusion The regimen consisting of docetaxel 30 mg/m2 (days 1, 8) and capecitabine 825 mg/m2 twice daily (days 1–14) was well tolerated. Capecitabine did not alter pharmacokinetics of docetaxel. Further testing of this regimen in tumor-specific trials, especially gastric, lung and breast cancer, is warranted.Presented at the 39th Annual Meeting of the American Society of Clinical Oncology, May 2003, Chicago, IL. 相似文献

Background
Access to specialty care is critical for patients with advanced stage lung cancer. This study assessed access to cancer specialists and cancer treatment in a broad population of patients with advanced stage lung cancer.Materials and Methods
Two study samples were extracted from 2 claims databases and analyzed independently: patients aged ≥ 18 years with de novo diagnosis of metastatic lung cancer in the MarketScan database between 2008 and 2014 (commercially insured adult patients; n = 22,268); and patients aged ≥ 65 years in the Surveillance, Epidemiology, and End Results–Medicare database with a diagnosis of advanced non–small-cell lung cancer between 2007 and 2011 (Medicare-insured elderly patients; n = 9651). The study period spanned from 6 weeks before the first lung biopsy tied to the initial lung cancer diagnosis until the end of continuous health insurance enrollment, or data availability, or death.Results
Among the commercially insured adults (MarketScan), most patients were seen by a cancer specialist within a month of first lung biopsy (80%), 12% were never seen by a cancer specialist, and 6% did not receive cancer-directed therapy. Among the Medicare-insured elderly patients (SEER–Medicare), the proportions were 79%, 4%, and 10%, respectively. Patients seen by a cancer specialist were more likely to receive cancer-directed therapy (95% vs. 92%, P < .001 and 92% vs. 38%, P < .001, respectively).Conclusion
Between 4% and 12% of patients with advanced stage lung cancer do not have appropriate access to cancer specialist, which appears to negatively affect access to optimal and timely treatment. 相似文献50.

A novel series of new flurbiprofen hydrazide derivatives 2-(2-fluorobiphenyl-4-yl)-N′-[(substituted phenyl/5-nitro-2-furyl)methylene]propanehydrazide (3a–k), 2-(2-fluorobiphenyl-4-yl)-N-(2-substituted-4-oxo-1,3-thiazolidine-3-yl)propanamide (4a–b, 4d–k), 2-[2-(2-fluorobiphenyl-4-yl) propanoyl]-N-substituted hydrazinecarbothioamide (5a–h) and 2-(2-fluorobiphenyl-4-yl)-N′-[(3-methyl-4-oxo-1,3-thiazolidin-2-ylidene]propanehydrazide (6a–b, 6e and 6g) has been synthesized in this study. All synthesized compounds were screened for antimicrobial activity against various bacterial and fungal strains. Additionally, compounds were evaluated for the ability to inhibit Hepatitis C virus NS5B polymerase. The most active 4-thiazolidinone compound was 4k (SGK119) with 67.0 % and thiosemicarbazide compound was 5d (SGK123) with 69.50 % inhibition at 200 μM against hepatitis C virus NS5B RNA polymerase. Anticancer activity of the selected compounds (3i, 3j, 3h, 4d, 4i and 6b) was determined at a single dose towards the full panel of 60 human cancer cell lines by the National Cancer Institute (NCI). 2-(2-Fluoro-4-biphenylyl)-N-[2-[4-(trifluoromethyl)phenyl]-4-oxo-1,3-thiazolidine-3-yl]propanamide 4d, containing thiazolidinone ring, demonstrated the most marked effect with 20.80 % growth percent on leukaemia cancer cell line SR at 10?5 M. The results demonstrated that none of the compounds tested have anticandidal and antifungal activities, but two of them (4a and 4i) showed antibacterial inhibition against Micrococcus luteus, and Staphylococcus cohnii and Staphylococcus aureus, respectively. 相似文献
