OBJECTIVES: The aims of the study were to determine: 1) how mucociliary activity in acute bacterial rhinosinusitis is affected; 2) how this activity is changed by therapy; 3) the effects of topical agents on mucociliary clearance, and 4) the most appropriate topical agent(s) to be used in the therapy of sinusitis. STUDY DESIGN: Five groups of patients with acute bacterial rhinosinusitis were studied prospectively. METHODS: All patients had 500 mg oral amoxicillin and 125 mg oral clavulanic acid preparations given three times daily for 3 weeks. According to the topical agent applications, these groups included: group I (n = 12), no topical treatment was given; group II (n = 14), two puffs for each nostril once daily of 50 microg/100 mL fluticasone propionate was given; group III (n = 9), one puff for each nostril three times daily of 0.05% oxymetazoline was given; group IV (n =12), 3% sodium chloride (NaCl) (buffered to pH 6.5-7 at room temperature) was given; and group V (n =13), 10-mL solutions of 0.9% NaCl (buffered to pH 6.5--7 at room temperature) were given for nasal irrigations three times daily. All patients had medication for 3 weeks and were controlled each week. The saccharin method was used to measure nasal mucociliary clearance. To investigate the early effects of the topical agents for groups II to V, an additional test was repeated 20 minutes after the basal mucociliary clearance recordings. The test was repeated in the first, second, and third weeks of the treatment. RESULTS: The mucociliary clearance was significantly slower in the acute bacterial rhinosinusitis group than in the control group. There was no significant difference between the basal mucociliary clearance and the 20th minute mucociliary clearance of the fluticasone propionate and 0.9% NaCl solution groups. The mean values of the basal and the 20 minute's mucociliary clearance of the oxymetazoline group were 24.72 +/- 6.16 and 15.5 +/- 7.45 minutes, respectively, which were statistically significant. The mean values of the basal and the 20th minute mucociliary clearance of the 3% NaCl solution groups were 19.45 +/- 9.35 and 15.45 +/- 8.20 minutes, respectively, which were also statistically significant. In the first group (without topical treatment), the basal mucociliary clearance became significantly shorter after the second week of treatment. In the first and second weeks of the treatment of the oxymetazoline group, the mucociliary clearance did not change significantly, but after the third week the mucociliary clearance was significantly shorter. In the 3% NaCl solution group, significant improvement began from the first week and continued through the third week. Comparing the basal and the third weeks' mucociliary clearance values among the groups, the oxymetazoline and 3% NaCl solution groups revealed more significant improvement than the other groups, but this improvement was not different from the improvement of group I. There was still a statistically significant difference in the mucociliary clearance of the post-treatment sinusitis groups from the control group. CONCLUSIONS: The oxymetazoline and 3% NaCl solution groups seemed to be more effective in mucociliary clearance, but there was no significant difference in improvement among the groups. The improvement of acute bacterial rhinosinusitis takes more than 3 weeks, according to the mucociliary clearance values of the groups. 相似文献

Spontaneous early exposure of implants can become a serious complication during the initial healing phase. These early perforations and partial exposure of the coverscrews are a foci for plaque accumulation which, if left untreated, may result in inflammation, damage to the periimplant mucosa, and possible bone loss. Sometimes, these exposures are so small so as not to be clinically visible. This article presents methods of diagnoses of perforated mucosa around submerged implants. In addition, an easy-to-use classification of the spontaneous early exposure is proposed. Treatment modalities to prevent or intercept mucositis during the initial healing phase, when early exposures occur, are suggested. 相似文献

The utilization of the metacarpal bones and interosseous muscles in the reconstruction of the hand should be based on the vascular anatomy of the metacarpal bones and the interosseous muscles. The authors studied the vascular anatomy of the metacarpal bones and the interosseous muscles to design a split metacarpal musculoosseous flap. Eighteen cadaveric hands from 9 cadavers were included in the study. The dorsal metacarpal arteries arise from the arch and course along the metacarpal bones closer to the ulnar borders of the bones supplying their periosteum through the muscular branches. Despite the indistinct pattern of muscular supply and anastomotic branches to the palmar surface, in all hands the arteries extend constantly along the metacarpal bone closer to the ulnar border. For defects or any pathology of the carpal bones, the metacarpal bones could be split at the ulnar border distally and a split metacarpal musculoosseous flap (based proximally depending on the dorsal metacarpal artery) could be performed (or based distally along with a distal intermetacarpal anastomosis). 相似文献

Objective: To evaluate the efficacy and toxicity of gemcitabine plus vinorelbine chemotherapy in patients with advanced bladder carcinoma who are unsuitable for or who have failed cisplatin-containing chemotherapy.Patients and Methods: Thirty-one patients with advanced transitional cell carcinoma (TCC) of the bladder were scheduled to receive gemcitabine and vinorelbine chemotherapy. Twenty-one patients had received no prior chemotherapy and their creatinine clearance was below 50 ml/min (group 1), and the remaining 10 patients did not respond to previous cisplatin-containing chemotherapy (group 2).Results: In group 1, objective response rate was 47.6%, including 2 (9.5%) complete and 8 (38.9%) partial responses. In group 2, partial response was observed in 2 (20%) patients. The median survival time for patients in group 1 and 2 were 15 months (range 3–23) and 7 months (range 3–21), respectively. Grades 3 or 4 leukopenia developed in 16.1% of patients. Overall, 12.9% of the patients suffered from grade 3 nonhematologic toxicity.Conclusion: Our preliminary data indicate that the combination of gemcitabine and vinorelbine is active and well tolerated especially in patients with advanced TCC who are unsuitable for cisplatin-based chemotherapy. 相似文献

PURPOSE: To report two patients, 3 and 40 years of age, respectively, each of whom had an isolated intramuscular hemangioma of an extraocular muscle. DESIGN: Two retrospective, interventional case reports. INTERVENTION: Incisional biopsy and short-term oral corticosteroids. MAIN OUTCOME MEASURES: Clinical observation and pathologic examination of specimens and tumor status, visual acuity, and ocular motility at final follow-up. RESULTS: Orbital magnetic resonance imaging revealed that, compared with other extraocular muscles, the tumor was isointense on T1-weighted scans and hyperintense on T2-weighted images. Marked homogeneous enhancement was observed after contrast agent administration. Biopsy results showed a hemangioma of the lateral rectus muscle with predominantly capillary-like small vessels in the child and a mixed small and large vessel type hemangioma of the medial rectus muscle in the adult. CONCLUSIONS: Intramuscular hemangiomas may cause painless, isolated extraocular muscle enlargement in children and in adults without disturbing the ocular motility. The tumors do not seem to be sensitive to systemic corticosteroid therapy. 相似文献

We describe a 45-yr-old woman with an intermediate type atrioventricular septal defect associated with a double-orifice left atrioventricular valve (DOLAV). We diagnosed this exceptional anomaly by intraoperative transesophageal echocardiography (TEE) during surgery that was scheduled for only a primum type atrial septal defect (ASD) repair. Preoperative transthoracic echocardiography and angiography revealed the ASD but could not demonstrate the DOLAV. We were able to repair this rare and challenging abnormality successfully under the guidance of TEE imaging during the operation. TEE provides valuable information about both anatomy and functional aspect of the valvular structures. Besides its proven role in cardiac surgery, intraoperative use of TEE also serves as a useful tool for diagnosis of such unexpected and potentially missed abnormalities. 相似文献
