2015—2019年四川省流感哨点监测结果分析

目的 描述四川省2015—2019年流感病毒流行特征,为疫情防控提供依据。方法 对流感监测系统上报的流感样病例数据开展回顾性流行病学分析。结果 2015—2019年间,四川省共监测流感样病例标本131 477份,其中阳性标本23 844份,流感阳性率为18.14%。2015—2019年四川省优势流感亚型主要为甲型H1N1,季节性H3N2和B(Victoria)系流感。流感阳性率随月份、季节而改变,四川省流感阳性率高峰主要出现在冬季,其次为秋季。甲型流感主要在秋冬季流行,乙型流感主要在冬春季流行。流感病毒阳性检出率在5～14岁组年龄段最高。结论 四川省流感有明显的冬季流行高峰,各型别呈交替流行。秋冬季应加强流感防控工作;甲型和乙型流感好发于5～14岁群体,应继续加强对儿童学生流感的防控。

Clinical presentation,viral kinetics,and management of human monkeypox cases from New Delhi,India 2022

We describe the clinical and demographic characteristics, virological follow-up, and management of five confirmed monkeypox cases from New Delhi, India without any international travel history. The viral load kinetics and viral clearance were estimated in oropharyngeal swabs (OPS), nasopharyngeal swabs (NPS), EDTA blood, serum, urine, and various lesion specimens on every fourth day of follow-up ranging from 5 to 24 post onset day (POD) of illness. All five cases presented with mild to moderate-grade intermittent fever, myalgia, and lesions on the genitals, groins, lower limb, trunk, and upper limb. Four cases had non-tender firm lymphadenopathy. No secondary complications or sexually transmitted infections were recorded in these cases except for the presence of viral hepatitis B infection marker hepatitis B virus surface antigen (HBsAg) in one case. All the cases were mild and had a good recovery. A higher viral load was detected in lesion fluid (POD 9), followed by lesion roof (POD 9), urine (POD 5), lesion base (POD 5), and OPS/NPS (POD 5). The monkeypox virus (MPXV) DNA was detected in clinical samples from 5th to 24th POD. These monkeypox cases without international travel history suggest the underdiagnosed monkeypox infection in the community. This emphasizes the need for active surveillance of MPXV in the high-risk population such as men having sex with men and female sex workers.     

Awake intubation of the adult trachea using the Bullard laryngo-scope

Awake intubation using the Bullard laryngoscope can be comfortably and easily performed in the adult. Five cases are presented in which tracheal intubation was performed under topical anaesthesia with light intravenous sedation. In each case, topical anaesthesia was performed by insertion of a Guedel oral airway, with lidocaine ointment applied to the inferior and posterior surfaces. In one case, Bullard intubation was successful where direct laryngoscopy and multiple attempts at bronchoscopic intubation by three different operators had failed. We conclude that the Bullard laryngoscope can be easily used in awake patients and may be a useful alternative where other methods for awake intubation have failed.

Mathematical aspects of the paternity index I=X/Y,especially in relation to the chance of non-exclusion of non-fathers

Summary In a previous paper the author mentioned some aspects of the paternity index I (=X/Y): Among false triplets the frequency of those with I equal to or higher than an (observed) I value of I ^x is considerably lower than 1/I ^x; among false triplets the mean value of I is equal to 1, and among non-excluded non-fathers it is equal to the inverse of the chance of non-exclusion; among true triplets the mean value of 1/I (=i) is equal to the chance of non-exclusion of non-fathers. In a statistical material rather strong deviations from some of these expectations were observed.In the present paper further characteristics of the distribution of I values were taken into consideration, and especially those that should hold if lnI would fit in with a normal distribution. It was supposed that with the aid of such a distribution the deviations mentioned above could be recognized as chance variability. It appears, however, that neither the logarithms of the paternity index, nor those of the zygosity index of twins (chosen as an analogous model that is more easily analysable than the paternity index) are really normally distributed. This, in turn, makes that estimates of probability of paternity, based on such a supposition, are of doubtful reliability. Besides it is concluded that also for other reasons other estimates than Essen-Möller's W (or I or i), as probability of first type errors, lead in practice to conclusions that are equally subdue to a priori suppositions as are W values and may be, in fact, much more erroneous than those.Special attention is paid to the statistical analysis of paternity studies with more than one alleged father, and it is concluded that in such cases the general formula that may be considered to be equivalent with Essen-Möller's formula for one-man paternity cases, i.e., W=X/(X+Y) or I/(I+1), must be W ₁=I ₁/(I+n); W ₂=I ₂/(I+n) etc. and certainly not W ₁=I ₁/(I+1); W ₂=I ₂/(I+1) etc.Dedicated to Prof. Dr. Erik Essen-Möller on the occasion of his 80th birthday     

纳洛酮加清开灵治疗野生蕈中毒30例疗效观察

目的：观察纳洛酮与清开灵合用治疗急性野生蕈中毒的临床疗效。方法：采用随机数字表法将86例患者随机分为3组。治疗组30例以纳络酮加清开灵治疗，纳洛酮组26例单用纳洛酮治疗，清开灵组30例单用清开灵治疗。观察3组患者症状好转时间、症状消失时间、重症清醒时间。治疗5天为1疗程，共治2－8疗程。结果：治疗组在症状好转时间、症状消失时间、清醒时间均明显短于纳洛酮组和清开灵组（P＜0．05，P＜0．01）。结论：纳洛酮与清开灵合用，可以从不同途径作用于脑组织，尽快改善中毒症状，减少脑损伤，二者合用尚可减少纳洛酮的用量，从而减少纳洛酮的心血管效应。     

Comparison of a new video-optical intubation stylet versus the conventional malleable stylet in simulated difficult tracheal intubation

Handling and efficacy of a new video-optical intubation stylet were assessed in a simulated difficult tracheal intubation setting and compared with a conventional malleable stylet. Forty-five anaesthetists performed 10 tracheal intubations using both techniques. Laryngoscopy was performed by the observer, who created a grade 3 view according the classification by Cormack and Lehane. The time taken to place the tracheal tube and the final tracheal tube positions were documented. Mean (SD) intubation time for the video-optical stylet was 20.4 (7.7) s and for the malleable stylet 10.2 (3.3) s (p<0.01). With the video-optical stylet the trachea was correctly intubated in all 225 attempts; with the malleable stylet 44 (19.6%) oesophageal and 44 (19.6%) endobronchial intubations occurred (p<0.01). The video-optical intubation stylet enabled us to recognise inappropriate tracheal tube positions and to correct them immediately. This equipment can be considered a reliable and effective tool for management of the difficult airway.     

口头尸检对河池市5～60岁死亡病例进行死因评估结果分析

目的 分析河池市5～60岁居民死亡主要原因，分析口头尸检(Verlbal Autopsy，VA)进行死因调查的效果。方法 建立死亡监测系统，对所有报告的监测区内5～60岁死亡个案进行口头尸检调查。结果 2002年7月-2003年6月金城江镇、东江镇共死亡624人，全人口总粗死亡率为4．67‰，标化死亡率为5．34‰，男女之比为1．71：1；5～60岁死亡病例248例，粗死亡率为2．10‰；导致5～60岁居民主要死亡原因为意外死亡、恶性肿瘤、心脑血管疾病、消化系统疾病等，其中意外死亡占死亡构成比的1／3；通过VA进行死因调查，使3．000%的错误死因定义得到更正、5．00％的不明死因得到诊断；无因伤寒导致的死亡。结论 交通事故成为当地5～60岁居民死亡的主要因素；随着社会经济发展，伤寒等肠道传染病已不是导致死亡的重要因素；使用VA对于死因的判定比一般的监测系统报告更为准确。
