Objective: To estimate the direct medical cost of severe hand, foot and mouth disease (HFMD) in patients aged less than five years. Methods: A stratified sampling method was used to collect data on severe HFMD cases reported in the National HFMD surveillance database between Jan 1, 2012, and Dec 31, 2013. The sampling was referenced with the national aetiologic distribution of Enterovirus A71 (EV-A71), Coxsackievirus A16 (CV-A16) and other Enteroviruses (OEV) for severe HFMD cases and the included cases were distributed among seven geographic regions (Northeast, North China, Northwest, Central China, Southwest, East China and South China). A nationwide telephone interview using a structured questionnaire was conducted to obtain the direct medical cost and any complications that occurred in patients during the outbreak of laboratory-confirmed HFMD. After excluding the cases who could not recall their medical expenses or complications, a total of 685 cases were included in the analysis. Kruskal-Wallis H test was used to analyze the differences among patients who reported different complications. Multiple linear regression with bootstrap analysis of 500 replicates was used to explore the factors that influenced the direct medical costs. Results: Of 685 patients analyzed, 456 (66.6%) were male and 229 (33.4%) were female. The direct medical costs P₅₀ (P₂₅, P₇₅) were 14 250 (10 301, 20 600) Yuan. In total, 127 (18.5%) patients were diagnosed with severe HFMD patients with respiratory disease, 38 (5.5%) patients were diagnosed with aseptic meningitis, and 378 (55.2%) with encephalitis/brainstem encephalitis/acute flaccid paralysis. Furthermore, 53 (18.5%) patients were diagnosed with myocarditis, 39 (5.7%) with pulmonary hemorrhage/pulmonary edema and 50 (7.3%) with cardiopulmonary failure. The median (interquartile range) direct medical costs were 12 360 (7 313, 16 480) Yuan for severe HFMD patients with respiratory disease, 13 803 (9 064, 19 930) Yuan for aseptic meningitis, 14 438 (11 000, 20 015) Yuan for encephalitis/brainstem encephalitis/acute flaccid paralysis, 14 800 (8 500, 21 218) Yuan for myocarditis, 20 600 (12 500, 31 130) Yuan for pulmonary hemorrhage/pulmonary edema, and 20 043 (12 772, 28 840) Yuan for cardiopulmonary failure (H=17.70, P<0.001). The results of multiple linear regression with bootstrap analysis revealed that the direct medical cost for severe HFMD patients from Central China was 7 881 (95% CI: 3 814-11 949) Yuan higher than that of North China; severe HFMD patients diagnosed with OEV had direct medical costs of 1 987 (95%CI: 206-3 769) Yuan less those associated with EV-A71; severe HFMD patients whose duration of illness was ≥21 d had 20 480 (95% CI: 10 985- 29 974) Yuan higher direct medical costs those whose illness lasted ≤5 d; the direct medical costs for severe HFMD patients with pulmonary hemorrhage/pulmonary edema and cardiopulmonary failure were 7 874 (95%CI: 3 723-12 026) and 9 855 (95% CI: 328- 19 382) Yuan higher, respectively, than that associated with respiratory disease. Conclusion The direct medical costs associated with severe HFMD were found to be substantial. The total cost was affected by the duration of the illness and the severity of any complications.

Objective To clarify the age patterns and types of differences so as to provide reference on prevention and interventions of hand,foot and mouth disease (HFMD) cases,in Hubei province.Methods We collected the HFMD case information of Hubei province from the Chinese National Notifiable Infectious Disease Reporting System in 2009-2015 while the information on pathogens from the laboratory monitoring system of Center for Disease Control and Prevention at all levels in Hubei province.All the data were stratified by age,disease severity,laboratory confirmation status,and serotypes of enterovirus.Results There were 495 783 reported HFMD cases from 2009 to 2015,in Hubei province,of which 1 045 were severe with 99 fatal.The annual notification rate was 1 231.0/106.HFMD cases were concentrated mainly in 0.5-5 year olds,with highest severity and mortality seen in 6-11 month-olds.The predominated pathogen in mild laboratory-confirmed cases each year,in order during 2009-2015 as:EV71,Cox A16,Cox A16,Cox A16,EV71,Cox A16 and other EV.HFMD showed semiannual peaks in April-June,November-December,and with more cases in the even years than in the odd years.Conclusions Children aged 0.5 to 5 years with 6 to 11 month-olds in particular,were the focused groups of attention in Hubei province.Our findings provided evidence for the improvement on monitoring program.Targeted intervention approaches should be strengthened to reduce the mortality and morbidity of HFMD in the province.

Objective To evaluate the health related quality of life (HRQoL) for severe hand,foot and mouth disease (HFMD) patients with different complications.Methods A national telephone interview under the EQ-5D proxy2 questionnaire (EQ-SD and EQ-VAS),was conducted to obtain the HRQoL of lab-confirmed severe HFMD patients,aged between six months and five-year-olds from the national communicable disease surveillance system from January 1,2012 to December 31,2013.Results A total of 685 severe HFMD cases were included in the study.A total of 456 (66.6％) of them were males with 75.8％ of them younger than three years old.A total of 337 (49.2％) and 407 (59.4％) of the participants reported that they had problems in mobility or daily activities.A total of 569 (83.1％) and 616 (89.9％) of the cases reported having problems in pain/discomfort or anxiety/depression.The average EQ-5D and EQ-VAS scores were 0.58 ± 0.23 and 53.6 ± 25.7,both were positively associated with the duration of illness.Mean quality adjusted life years loss during the HFMD episode for the severe patients was (15.45 ± 13.75) years/1 000 persons.The QALY losses for severe patients with each of below complication were:respiratory diseases (11.17 ± 8.83) years/1 000 persons,aseptic meningitis (13.56 ± 11.99) years/1 000 persons,encephalitis/brainstem encephalitis/acute flaccid paralysis (AFP) (15.31 ± 12.63) years/1 000 persons,Myocarditis (17.28 ± 18.16) years/1 000 persons,pulmonary hemorrhage/pulmonary edema (17.34 ±14.98) years/1 000 persons,cardiopulmonary failure (25.47 ± 20.53) years/1 000 persons.Among patients with lab confirmed Entero virus A71 (EV71) (16.51 ± 14.48) years/l 000 persons,the QALY loss was seen higher than Coxsackie virus A16 (Cox A16) (13.02± 11.45) years/1 000 persons and other Enter virus (14.74 ± 14.22) years/1 000 persons (Z=11.83,P=0.003).Conclusion The HRQoL loss for severe HFMD patients substantially increased under complications exacerbation and related to the duration of illness.

Objective:To investigate the clinical efficacy of transfer of a free segment of the proximal second toe interphalangeal joint composite tissue flap in reconstruction of defects of interphalangeal joint of fingers, and simultaneously reconstruct the donor site defect left with the second toe by a transfer of a pedicled bone flap of the fibular proximal great toe.Methods:From December 2020 to April 2023, a total of 9 patients with interphalangeal joint defects of fingers were treated in the Department of Hand Microsurgery of Shunde Heping Surgery Hospital. The patients were 7 males and 2 females, aged 18-55 years old, with an average age of 31 years old. Firstly, transfers of a free segment of the proximal second toe interphalangeal joint composite tissue flap were performed to reconstruct the defects of finger joints. Simultaneously in the surgery, transfers of the fibular pedicled bone flap of the proximal great toe were conducted to reconstruct the donor site defects left in the second toe. Patients were instructed with appropriate postoperative functional exercises. K-wires were removed at 8-12 weeks after surgery. Outpatient visits, telephone and WeChat follow-ups were conducted to evaluate the appearance and functional recovery of the reconstructed interphalangeal joints and donor feet. Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, Vancouver Scar Scale (VSS) and American Orthopedic Foot and Ankle Society (AOFAS) foot function scoring standards were employed in the evaluation.Results:Postoperative follow-up lasted for 6 to 30 months. All of the 9 interphalangeal joint composite tissue flaps in the fingers survived with complete and good appearance. Function of the reconstructed interphalangeal joints of the fingers recovered well. According to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, the average score achieved 12 points, with 6 patients of excellent, 2 of good and 1 of fair. After surgery, the appearance and function of the donor great toes and second toes all recovered well. The average score of the scars in donor second toe evaluated by VSS was 4 points. All the donor feet were kept with 5 toes, with full, intact and good in appearance. According to the AOFAS foot function scoring standard, the average score achieved 95 points, and were excellent.Conclusion:Application of transfer of free proximal segment of interphalangeal joint composite tissue flap of the second toe in reconstruction of the interphalangeal joint defect of a finger, and simultaneously reconstruct the defect left with the donor second toe with a fibular proximal great toe flap pedicled with bone tissue can achieve good clinical efficacy in reconstruction of the defects of interphalangeal joint of fingers, restore the function of the interphalangeal joint of fingers and the appearance and function of the donor foot.

Objective Through analyzing the surveillance data on typhoid fever and paratyphoid fever in 2015 to understand the related epidemiological features and most possible clustering areas of high incidence.Methods Individual data was collected from the passive surveillance program and analyzed by descriptive statistic method.Characteristics on seasonal,regional and distribution of the diseases were described.Spatial-temporal clustering characteristics were estimated,under the retrospective space-time method.Results A total of 8 850 typhoid fever cases were reported from the surveillance system,with incidence rate as 0.65/100 000.The number of paratyphoid fever cases was 2 794,with incidence rate as 0.21/100 000.Both cases of typhoid fever and paratyphoid fever occurred all year round,with high epidemic season from May to October.Most cases involved farmers (39.68％),children (15.89％) and students (12.01％).Children under 5 years showed the highest incidence rate.Retrospective space-time analysis for provinces with high incidence rates would include Yurnan,Guangxi,Guizhou,Hunan and Guangdong,indicating the first and second class clusters were mainly distributed near the bordering adjacent districts and counties among the provinces.Conclusion In 2015,the prevalence rates of typhoid fever and paratyphoid fever were low,however with regional high prevalence areas.Cross regional transmission existed among provinces with high incidence rates which might be responsible for the clusters to appear in these areas.

Objective To investigate the clinical severity,etiological classification and risk factors of severe cases with hand,foot and mouth disease (HFMD).Methods A total of 1 489 records on severe and fatal HFMD cases reported to the national pilot surveillance system of HFMD were used to analyze the demographic,medical treatment,etiological classification of the cases.Treatment outcome related risk factors were also studied with multi-variable stepwise logistic regression method.Results Seven out of the 1 489 severe HFMD cases died of this disease.A total of 960 (72.9％) were under three years old and 62.9％ were male and most of the cases (937,62.9％) resided in rural areas.Among all the cases,494 (33.2％) went to seek the first medical assistance at the institutions of village or township level.Durations between disease onset and first medical attendance,being diagnosed as the disease or diagnosed as severe cases were 0(0-1) d,1 (0-2) d and 2 (1-4) d,respectively.In total,773 (51.9％) of the severe HFMD cases were diagnosed as with aseptic meningitis,260 (17.5％) with brainstem encephalitis,377 (25.3 ％) with non-brainstem encephalitis,6 (0.4％) with encephalomyelitis,1 (0.1％) with acute flaccid paralysis,4 (0.3％) with pulmonary hemorrhage/pulmonary edema and 68 (4.6％) with cardiopulmonary failure.Of the etiologically diagnosed 1 217 severe and fatal HFMD cases,642 (52.8％) were with EV71,other enterovirus 261 (21.5％),Cox A16 36 (3.0％),1 (0.1％) with both EV71 and Cox A16.However,277 (22.8％) showed negative on any pathogenic virus.Complication (Z=3.15,P=0.002) and duration between onset and diagnosed as severe cases (Z=3.95,P＜0.001) were shown as key factors related to treatment outcomes.Conclusions Most severe HFMD cases appeared in boys,especially living in the rural areas.Frequently seen complications would include aseptic meningitis,non-brainstem encephalitis and brainstem encephalitis.EV71 was the dominant etiology for severe and fatal cases.Early diagnosis and complication control were crucial,related to the treatment outcome of HFMD.

Most common causative agents for hand, foot and mouth disease (HFMD) are enterovirus 71 (EV-A71) and coxsackievirus A16 (CV-A16). The symptomatic and asymptomatic cases could transmit the disease in population. Many sero-epidemiological surveys were launched to estimate the sero-incidence of EV-A71 and CV-A16 enterovirus, the susceptibility of different sub-population, and to observe the dynamics of neutralizing antibody. A literature search of sero-epidemiological study focused on EV-A71 or CV-A16 was conducted via PubMed and China Hospital Knowledge Database. Based on the 20 selected studies, the different age groups' antibody level, the susceptibility, the dynamics of antibody and sero-incidence of EV-A71 or CV-A16 were analyzed. From our results, the antibody level against EV-A71 or CV-A16 in neonates was associated with their mothers, which was similar with that of adults. The antibody level against EV-A71 or CV-A16 in neonates dropped to lowest level at one years-old, and started to dramatically increase until four years-old, and reached a plateau at five years-old. In conclusion, the infants aged 6-12 months were the priority group to receive vaccination when the EV-A71 vaccine is licensed in the future.

Objective: To understand the characteristics relating to the etiology and complications of hand, foot and mouth disease (HFMD) based on data from the pilot National Sentinel Surveillance (NSS) program so as to explore the feasibility, advantages and disadvantages of the NSS. Methods: Data were extracted from the NSS system, conducted in 11 provinces of China from November 2015 to October 2016. Characteristics regarding the etiology, complications of HFMD and factors related to the positive rates of HFMD specimens were analyzed under the logistic regression method by SPSS 20.0 software. Results: A total of 4 783 specimens were collected, including 3 390 from mild, 1 390 from severe and 3 from death cases. The overall positive rate was 81.43% (3 895/4 783). Other enteroviruses (non EV71/Cox A16 enteroviruses) appeared the major serotype (52.68%, 1 482/2 813) for mild infection of the disease while EV71 was for the severe cases (65.31%, 706/1 081). The serotype spectrum revealed by the pilot NSS was almost identical with the existing surveillance system. Other enteroviruses tended to infect younger children (χ²=130.17, P<0.001) than EV71 and Cox A16, in China. The multivariate logistic regression results showed that higher positive rate was associated with specimens which were collected from males, at children’ hospitals, in peak seasons, timely and in stools. The positive rates presented downwarding trends with the extension of the onset-sampling interval (χ²=14.47, P<0.001 in stool specimen; χ²=31.99, P<0.001 in throat swab; χ²=24.26, P<0.001 in anal swab). Aseptic meningitis, non-brainstem encephalitis and brainstem encephalitis appeared the top three complications of both EV71-associated and other enteroviruses-associated severe HFMD cases. Conclusions Factors as gender, season/place/timeliness of specimen collection, and types of hospital all appeared independently influenced the positive rates. NSS seemed feasible to be used as an alternative or supplement tool to the existing surveillance program in China.
