Objective To investigate and analyze the clinical features of children with colorectal polyps and the efficacy of laparoscopic surgery combined with colonoscopy. Methods A total of 98 children with colorectal polyps diagnosed and treated in our hospital from February 2019 to October 2021 were selected as subjects of this study. The clinical characteristics of all children were recorded,and they were divided into the laparoscopic group(laparoscopic surgery combined with colonoscopy,n=40)and the colonoscopy group(colonoscopy,n=58)according to the differences in surgical methods. The therapeutic effect,complication rate,VAS pain score,polyp recurrence and reoperation rate of different surgical methods were compared. Results Among the 98 children,the polyps of 44 cases were in rectum,38 cases in transverse rectum and 16 cases in other sites. The maximum diameter of polyp was(1. 65±0. 24)cm. Polyps were solitary in 83 cases and multiple in 15 cases. The perioperative indexes in the laparoscopic group were significantly improved compared with those in the colonoscopy group(P<0. 05). The incidence of postoperative complications such as infection,bleeding,intestinal perforation and intestinal obstruction was 5. 00% in the laparoscopy group,which was significantly lower than 17. 24% in the colonoscopy group(P<0. 05). The total effective rate of laparoscopic group was 97. 50% one month after operation,which was significantly higher than that of colonoscopy group(82. 76%,P<0. 05). The VAS pain score of the laparoscopic surgery group was significantly lower than that of the colonoscopy group at 1,3 and 7 days after surgery(P<0. 05). After 1 year of follow-up,the combined polyp recurrence rate and reoperation rate were 5. 00% and 2. 50%,which were significantly reduced compared with 18. 97% and 13. 79% in colonoscopy group(P<0. 05). Conclusions The main sites of colorectal polyps in children are rectum and transverse rectum,and most of them are solitary. Laparoscopic and colonoscopic surgery for colorectal polyps in children can promote the recovery of children,improve the overall treatment effect of patients,relieve the pain of children,reduce the occurrence of complications,and reduce the recurrence rate and reoperation rate of follow-up polyps in children.

Methods From January 20, 2020 to February 29, 2020, a retrospective analysis was carried out on 129 suspected cases of 2019-nCoV infection admitted to the isolation ward of the only medical unit designated for children in Guangzhou. The epidemiology, disease characteristics, clinical characteristics, laboratory examination, outcome and follow-up were summarized and analyzed. Results There were 79 males and 50 females, with a minimum age of 1 month and a maximum age of 13 years. Anong them, 51 cases (39.5%) had a history of tourism or residence in the epidemic area of Wuhan, 20 cases (15.5%) had a history of contact with people with respiratory symptoms from the epidemic area, 17 cases (13.1%) with a confirmed case in the surrounding area or community, 3 cases (2.3%) had a history of contact with a confirmed patient (2 of them were family clustering cases), 38 cases (29.5%) were clinically suspected cases. Clinical symptoms: 121 cases with fever (93.8%), 92 cases with coughing (71.3%), 50 cases with runny nose (38.8%), 32 cases with diarrhea, vomiting or abdominal pain (24.8%). In 102 cases (79.0%), white blood cells were decreased or normal, 103 cases (79.8%) with CRP＜20 mg/L, and 57 cases (44.2%) showed focal infection on chest X-ray or CT scan. Etiological examination: only one case (0.78%) of the family confirmed cases had positive anal swab result, but the throat swab results were negative all the time. The anal swab and throat swab results of other patients and the throat swab results of their accompanying family members were negative. Other pathogens were detected in 61 cases (47.3%), including 14 RSV positive cases, 9 influenza A positive cases, 8 human metapneumovirus positive cases, 6 enterovirus positive cases, 6 influenza B positive cases, 6 Mycoplasma pneumoniae positive cases, 4 parainfluenza virus type 1 positive cases, 1 parainfluenza virus type 3 positive cases, 2 human bocavirus positive cases, 3 adenovirus positive cases, 1 Klebsiella pneumoniae positive cases, 1 Human Staphylococcus positive case, and 1 case with parainfluenza virus type 1 and human bocavirus. The only confirmed patient was followed up while multiple pharyngeal swab results were negative, and the positive anal swab results lasted for 19 days before turning negative and remained asymptomatic. Other patients were followed up on the 3rd, 7th and 14th day after discharge, and no abnormal findings were found. Conclusion Screening/suspected cases of 2019-nCoV infection in children were mostly clinically manifested as respiratory or gastrointestinal symptoms. The diagnosis rate of nucleic acids was extremely low, and there was a possibility of missed diagnosis. Nearly 50% of cases could find other relevant pathogens excluding the 2019-nCoV. The positive rate of anal swab results was higher than that of pharyngeal swab.

目的 探讨右美托咪定与咪达唑仑在儿童牙科患者术前镇静中的作用及安全性。方法 选取2020年6月—2021年1月需行择期全麻牙科治疗的60例患儿作为研究资料,将其根据数字法随机分为对照组(采取咪达唑仑)与观察组(采取右美托咪定)各30例,比较2组患儿的镇静效果。结果 2组患儿经麻醉后,观察组患儿的自主呼吸恢复时间、苏醒时间以及拔管时间低于对照组,经统计学分析有差异(P＜0.05);患儿在给药前Ramsay镇静评分中比较无差异;在给药10 min、20 min、30 min时Ramsay镇静评分均能达到2分以上,但经统计学比较无差异;血氧饱和度未发现异常,而且在给药观察期间患儿的血氧饱和度也在95%以上;但经统计学分析,患儿在给药前和给药10 min、20 min、30 min时心率、呼吸以及血氧饱和度均无差异(P＞0.05)。结论 右美托咪定与咪达唑仑均能成功用于儿童牙科患者术前镇静中,但经本文研究发现右美托咪定其效果更为显著些,而且绝大多数患儿能够配合与父母分离、配合麻醉面罩,降低患儿术后躁动发生率。
