ABSTRACT
Objective To evaluate the effect of surgery combined with aminolevulinic acid (ALA)-based photodynamic therapy (PDT) on the prognosis of extramammary Paget's disease.Methods A prospective open-labelled controlled trial was conducted.A total of 38 patients with pathologically comfirmed extramammary Paget's disease were enrolled from Shanghai Dermatology Hospital,and divided into 2 groups to be treated with surgery alone (surgery alone group,n =21) or surgery combined with ALA-PDT (combination group,n =17).Patients in the combination group received ALA-PDT after the surgery once every two weeks for 3 sessions.All the patients were followed up once every three months for more than 12 months,and the incidence of relapse was evaluated and compared between the 2 groups after the treatment.Results During the follow-up of 12-58 months (mean,35.45 ± 16.98 months),7 patients in the surgery alone group experienced relapse,and the median time to relapse was 9 months,with an upper quartile of 18 months and a lower quartile of 6 months.However,relapse only occurred in 1 patient in the combination group,and the time to relapse was 18 months after the end of treatment.The recurrence rate was significantly lower in the combination group than in the surgery alone group (P ＜ 0.05),and the time to relapse was also longer in the combination group than in the surgery alone group.Furthermore,ALA-PDT after the surgery was well tolerated in all the patients.Conclusion Surgery combined with ALA-PDT can reduce the recurrence rate of extramammary Paget's disease,and improve its prognosis.
ABSTRACT
Objective To investigate the changes in severe burn patients with acute renal failure by using continuous blood purification(CBP). Methods Twelve severe bum patients underwent early CBP were included in this study. The levels of creatinine、blood urea nitrogen and interleukin-6(IL-6) in plasma were determined. The termperature and heart were also observed. Results After the treatment of CBP,the clinical symptoms were improved obviously ( P ＜ 0. 05 ). The levels of creatinine[( 376. 2 ± 24. 5 ) μ mol/L vs ( 145.2 ± 57. 1 ) μmol/L] 、sodium concentration [( 5.3 ± 1.6 ) mmol/L vs ( 4. 0 ± 0. 7 ) mmol/L] and potassium concentration [( 153. 4 ± 13.0 ) mmol/L vs( 140. 1 ±8.6)mmol/L]in plasma were all decreased evidently after the treatment of CBP. There were significant differences ( t = 2. 79,3.06,3. 01, P ＜ 0. 05 ). The levels of IL-6 and APACHE Ⅱ score were ( 264. 31 ± 122.42 ) ng/Land( 15.2 ±5.8) scores before treatment. While after treatment,their levels were(94. 18 ±63. 82) ng/L and(5.4 ±3. 6) scores. The difference was also significant ( t = 4. 17,3. 67, P ＜ 0. 05 ). In this study, 8 patients cured and 4 patients died. Conclusion CBP could eliminate inflammation factors effectively in severe burn patients with acute renal failure. It could afford a useful assist treatment to these patients.
ABSTRACT
Objective To investigate and report a group of patients with cutaneous nocardiosis occurring in China.Methods The skin lesion of twenty-three patients were examined and the pathogen was identified.The possible cause of this disease was also investigated.Results All the twenty-three patients belon g to a same village in a province.Skin lesions on buttoc ks manifested as nodules and abscesses whereas some other lesions as ulcers and draining sinuses,occurring 2-10mo nths after intramuscular injection.The pathogens were identified as Nocardia asteroides.Conclusion Twenty-three patients of cutaneous nocardiosis were related to intramu scular injection.
