We report a case of endobronchial metastasis from prostate adenocarcinoma. A patient with a history of prostate cancer under
complete androgen blockade presented to the respiratory department complaining of dyspnea and dry coughing. Flexible bronchoscopy
showed multiple polypoid lesions in the tracheobronchial tree and the immunohistochemical studies on the biopsy specimen determined
the diagnosis. The patient was treated with paclitaxel, estramustine phosphate and carboplatine, and experienced symptoms
suppression. To our knowledge, this is the first case of endobronchial metastasis of a patient with androgen refractory prostate
cancer without any evidence of extrathoracic metastasis. The current report also emphasises the need for a multidisciplinary
approach for cases of endobronchial metastases, with the collaboration of pneumologists, urologists, pathologists and oncologists. 相似文献

BACKGROUND: Although the effect of statins on lowering low-density lipoprotein cholesterol (LDL-C) has been extensively studied, their hypotriglyceridemic capacity is not fully understood. OBJECTIVE: The present study examined clinical and laboratory factors potentially associated with the triglyceride (TG)-lowering effect of rosuvastatin. METHODS: Eligible patients had primary dyslipidemia and a moderate risk of heart disease. Patients were prescribed rosuvastatin 10 mg/d in an open-label fashion and kept 3-day food diaries. Laboratory measurements, performed at baseline and 12 weeks, included serum lipid parameters (total cholesterol [TC], TGs, LDL-C, high-density lipoprotein cholesterol [HDL-C], and apolipoprotein [apo] levels), non-lipid metabolic variables (including carbohydrate metabolism parameters and renal, liver, and thyroid function tests), and LDL-subfraction profile (by high-resolution 3% polyacrylamide gel electrophoresis). Tolerability was assessed at each visit. RESULTS: Participants were 75 hyperlipidemic patients (39 men and 36 women; mean age, 51.7 years). At 12 weeks, TC levels were reduced by 35.1% (P < 0.001), TGs by 15.2% (P < 0.001), LDL-C by 48.5% (P < 0.001), apoE by 35.4% (P < 0.001), and apoE by 17.3% (P < 0.001) from baseline, whereas HDL-C and apoA1 levels were not significantly changed. Stepwise linear regression analysis showed that baseline TG levels were most significantly correlated (R(2) = 42.0%; P < 0.001) with the TG-lowering effect of rosuvastatin, followed by the reduction in apoCIII levels (R(2) = 13.6%; P < 0.01). Rosuvastatin use was associated with a reduction in cholesterol mass of both large LDL particles (mean [SD], from 150.5 [36.6] to 90.5 [24.3] mg/dL; P < 0.001) and small, dense LDL (sdLDL) particles (from 11.5 [8.4] to 6.6 [4.5] mg/dL; P < 0.001). Rosuvastatin had no effect on cholesterol distribution of the LDL subfractions (mean [SD], large particles, from 90.8% [7.0%] to 91.8% [5.1%]; sdLDL, from 7.1% [4.7%] to 7.5% [4.8%]) or the mean LDL particle size (from 26.5 [4.2] to 26.6 [4.0] rim). A significant increase in mean LDL particle size after rosuvastatin treatment (mean [SD], from 26.4 [0.4] to 26.9 [0.4] rim; P = 0.02) was observed only in patients with baseline TG levels > or =120 mg/dL. No serious adverse events requiring study treatment discontinuation were reported. One patient who presented with headache and 2 patients who presented with fatigue quickly recovered without discontinuing rosuvastatin treatment. A posttreatment elevation in aminotransferase levels <3-fold the upper limit of normal (ULN) was recorded in 5 (6.7%) patients, and 2 (2.7%) patients experienced elevated creatine kinase concentrations <5-fold ULN. CONCLUSION: Baseline TG levels were the most important independent variable associated with the TG-lowering effect of rosuvastatin. 相似文献

In vitro evaluation of the effectiveness of calcium hydroxide and paramonochlorophenol on anaerobic bacteria from the root canal 总被引:9,自引:0,他引:9
Abstract The effectiveness of calcium hydroxide and paramonochlorophenol (PMCP) was tested on anaerobic bacteria isolated from infected root canals, at time intervals 5, 15, 30 and 60 min. The experimental method used was similar to that proposed by the German Society of Hygiene and Microbiology (DGHM), with slight modifications. Testing revealed that calcium hydroxide was significantly more effective than PMCP against the total number of anaerobes. Additionaly, it was proved to be quickly and highly effective against some microorganisms related to severe clinical symptoms, such as B. melaninogenicus and P. gingivalis as well as against actinomyces species. 相似文献

The purpose of the present study was to examine the flora from the root canals and periodontal pockets of teeth with advanced periodontal disease in order to compare the predominant cultivable microflora from the canals with those found in the adjacent periodontal pockets. Three samples were collected from each of sixteen patients, one from the root canal and two from the adjacent periodontal pocket in two different sites. Criteria for inclusion in the survey were pocket depth of greater than or equal to 7 mm, intact clinical crowns, and lack of periapical lesions. The study has demonstrated that the microorganisms present in the root canals of caries-free teeth with advanced periodontitis generally resembled those found in the adjacent periodontal pockets. The similarity in the recovery of organisms in the current study suggests that the pocket could be the source of the root canal infections. Further investigation is needed to clarify whether such factors as duration of periodontitis and age of the patient play a role in pulpal pathosis and whether the presence of specific bacterial species is also a factor in the etiology and pathogenesis of pulp disease. 相似文献

Microflora in adult periodontitis 总被引:3,自引:0,他引:3
The subgingival microflora of adult periodontitis was studied in 8 adults (36–47 years) and compared with that of 10 periodontally healthy individuals (36–43 years). A total of 64 periodontal lesions were examined, and classified according to the attachment level in three categories: attachment loss >6 mm, attachment loss 4–6 mm and attachment loss <4 mm. Also for comparative purposes 20 gingival sulci were evaluated. Samples were taken using three standardized paper points and were incubated anaerobically in selective and non-selective media. The results showed a statistically significant association of Capnocytophaga gingivalis and Capnocytophaga sputigena with moderate periodontal lesions, while Haemophilus segnis has been correlated to severe periodontal lesions. We concluded that C. gingivalis, C. sputigena and H. segnis might be potentially conducive to periodontal deterioration in adult periodontitis. 相似文献

A diversity of microbial species has been detected in children's oral flora at an early age. To investigate the composition of the subgingival microbiota of different groups of teeth in children with mixed dentition, 40 systemically healthy children, aged 7-8 years, randomly chosen, were examined. Subgingival plaque samples were taken from the mesiobuccal sites of 21, 41, 16 and 36 permanent teeth and 53, 73, 64 and 84 deciduous teeth. The samples were cultured for bacterial isolation anaerobically and in 10% CO2 plus air using selective and nonselective media. Forty-five different microbial species were isolated from both permanent and deciduous teeth. Streptococcus sanguis (79-70%), Streptococcus mitis (66-65%), Prevotella melaninogenica (51-57%), Eikenella corrodens (51-52%), Capnocytophaga gingivalis (46-34%), Capnocytophaga ochracea (45-45%), Actinomyces naeslundii (39-60%) and Prevotella intermedia (42-35%) were among the most frequently detected species in permanent and deciduous teeth respectively. Several suspected periodontal pathogens, such as Porphyromonas gingivalis, Prevotella loescheii, Campylobacter gracilis, Bacteroides forsythus, Campylobacter concisus, Peptostreptococcus micros and Selenomonas sputigena, albeit less frequently detected, were present in the microbiota of these children. The bacterial species Streptococcus constellatus, Peptostreptococcus micros, Pseudoramibacter alactolyticus, E. corrodens and Fusobacterium nucleatum were associated with non-bleeding permanent and deciduous teeth whereas Streptococcus intermedius, C. concisus, P. intermedia and P. loescheii were associated with bleeding. 相似文献
