Objective:
To investigate whether the combination of oral propranolol and topical 0.5% timolol maleate cream is more effective than oral propranolol alone for treating infantile hemangioma (IH).
Methods:
From September 2015 to July 2016, 14 patients with proliferative IH, visited the infantile hemangioma outpatient clinic of the Department of Plastic and Reconstructive Surgery of Shanghai 9th People′s Hospital, were enrolled in this study. All patients took oral propranolol. Half of each IH lesion was treated with 0.5% timolol maleate cream. There were 5 male patients and 9 female patients, aged from 1.5 to 5.0 months. After 4 months of treatment, the color, size, extent, volume and the overall clinical outcomes of each lesion were measured, and the side effects were recorded. The therapeutic outcomes of oral propranolol alone and the combination of propranolol and timolol were analyzed and compared using Wilcoxon matched-pair signed-rank nonparametric tests.
Results:
Both oral propranolol alone and oral propranolol combined with topical 0.5% timolol maleate cream were proved to effectively improve the regression of IH with minor side effects. The color VAS score of oral propranolol alone group was 6.92±2.63, while the combination group was 6.88±2.33 (

Objective To investigate the anesthesia residents' proficiency in the epidural puncture and training needs using questionnaire survey in China.Methods A questionnaire designed by ourselves was sent to anesthesia residents via the WeChat platform within 1 month.The data were recorded by the system automatically.Results A total of 795 anesthesia residents involved in the investigation,and the number of valid questionnaires was 753 (94.7%).There were 233 (30.9%) junior residents (0-2 yr of training),279 (37.1%) semi-senior residents (3-5 yr of training),and 241 (32.0%) senior residents (>5yr of training).Compared with junior group,the difficulty score for epidural puncture was significantly decreased,and the confidence scores for performing normal middle lumbar,difficult lumbar,lateral lumbar and thoracic epidural puncture were increased in semi-senior and senior groups (P<0.05).Compared with semi-senior group,the difficulty score for epidural puncture was significantly decreased,and the confidence scores for performing normal middle lumbar,difficult lumbar,lateral lumbar and thoracic epidural puncture were increased in senior group (P<0.05).The self-evaluated difficulty of epidural puncture was lower as the number of prior epidural cases was more (r=-0.719,P<0.01).There were 46.6% of the residents who had received simulation-based training before performing epidural puncture on the patient,among which most residents considered the simulation-based training is effective in helping to familiarize with procedure (77.2%),familiarize with anatomy (70.4%),simulate the texture of different layers (47.9%),and enhance success rate of epidural puncture (56.7%).There were 75.0% residents who considered visualization technology is helpful in enhancing the success rate and confidence of epidural puncture.Conclusion Currently,the proficiency of junior anesthesia residents in epidural puncture needs to be strengthened.The simulation-based training has not been widely applied in the epidural training,while residents think high of simulation-based training and are looking forward to visualization technique training.

Objective:To explore the safety and efficacy of radiofrequency in the treatment of overactive bladder(OAB).Methods:A prospective, multicenter, non-randomized controlled trial was conducted. Eligible patients were divided into test group and control group in Zhejiang Provincial People’Hospital, The First Affiliated Hospital of Wenzhou Medical University, and Sir Run Run Shaw Hospital affiliated to Zhejiang University School of Medicine from March 2019 to June 2020. Inclusion criteria: patients diagnosed with OAB, and bladder capacity>100ml. Exclusion criteria: pregnant and lactating women; patients with secondary OAB symptoms such as urinary tract obstruction; patients with uncontrolled urinary tract infection within 1 week; patients in stable stage by using other treatment methods; patients implanted with any nerve stimulator, cardiac pacemaker or implantable defibrillator; patients with malignant tumors, serious cardiovascular, cerebrovascular diseases, renal insufficiency or received BTX treatment in recent 12 months. The patients were allocated to test group and the control group in a ratio of 2∶1 according to the time sequence of the visit. The patients in the test group were treated with radiofrequency treatment. After entering the group, they were treated for 4 times at the 1st, 2nd, 7th and 8th week respectively. In the control group, the energy was turned off during the radiofrequency treatment. The patients were followed-up every week until the end of the 12th week. The treatment success rate [the average frequency of urination in 24 h was reduced more than 50% from the baseline or returned to the normal (≤8 times/day) or the average frequency of urgent urination in 24 h was reduced more than 50% from the baseline], the frequency of urination, urgent urination and nocturnal urination before and after treatment, the residual urine volume of the bladder, the quality of life (QOL) score and the occurrence of catheter related adverse events in two groups were compared.Results:114 patients were enrolled in the study, including 76 patients in the test group and 38 patients in the control group. There were no significant differences in the age [(44.2±12.8) vs. (41.7 ± 12.1) years old], male female ratio (13/63 vs. 4/34), average course of disease [2.0(1.2, 5.0) vs. 2.0 (1.0, 4.0) years], the frequency of urination[12.8 (10.6, 16.8) vs. 12.8 (10.3, 17.0) times], urgency urination [11.8(9.3, 15.8) vs. 11.8 (9.0, 17.0) times], nocturia [2.7 (1.3, 3.7) vs. 2.3(0.7, 3.3) times], residual urine volume of bladder [12.0 (3.0, 28.0) vs. 14.0 (3.7, 20.0) ml ] and the QOL score [5.0(4.0, 5.0) vs. 4.0(4.0, 5.0)]before the treatment between the two groups ( P>0.05). The treatment success rate in the test group was 76.3% (58/76), while 26.3% (10/38) in the control group, with a statistically significant difference ( P<0.01). There were significant differences between the test group and control group in the frequency of urination [9.7 (7.7, 12.0) vs. 12.9 (9.6, 15.7) times], urgent urination [7.3 (5.0, 10.0) vs. 11.7 (7.3, 15.3) times], nocturia [1.3 (0.7, 2.0) vs. 1.7 (1.0, 3.0) times] and the QOL score of the patients[3.0(1.0, 3.0) vs. 4.0(3.0, 4.5)]after the treatment(all P<0.05). The frequency of urination, urgency urination, nocturia, the residual urine volume and the QOL score in the test group were significantly improved ( P<0.05) after the treatment.The frequency of urination, nocturia, residual urine volume and the QOL score in the control group were improved ( P<0.05) after the treatment. 13 (11.4%) patients had catheter related adverse events. In the test group and the control group, there were 7 cases of macroscopic hemorrhage caused by the placement of instruments (5/76 vs. 2/38), 5 cases of acute urinary tract infection within 3 days (3/76 vs. 2/38), and 1 case of instrument breakage (catheter breakage) (0/76 vs. 1/38). There were no significant differences in the adverse events between the two groups ( P> 0.05). Conclusions:Radiofrequency treatment of OAB can effectively improve the symptoms of patients, improve the QOL of patients, and has low incidence of adverse events, with good efficacy and safety.
