[Abstract]:Research background
Foot and mouth disease (hand-foot-and-mouth disease HPMD) is a common infectious disease caused by a variety of intestinal virus, mainly in infants, HFMD are the main pathogens caused by enterovirus 71 (Enterovirus type71, referred to as EV71) and Coxsackie virus type eight group 16 (Coxsakie virus group A type16, referred to as CoxA16) as a global epidemic. In recent years, HFMD has become more and more threat to children's health at home and abroad widely epidemic of.HFMD patients with mild and usually asymptomatic or only mild discomfort, often manifested as fever, oral herpes, ulcer, hand, foot and buttocks rash, herpes, cured in 1 weeks, but a minority of patients develop to severe, often associated with meningitis, encephalitis, acute flaccid paralysis, severe complications of neurogenic pulmonary edema, rapid progression, and even lead to death in children with severe cases. At present, HFMD is still on Therefore, it is essential to identify the high risk factors of HFMD for positive treatment, improvement of prognosis and reduction of mortality.
The first part analysis of the high risk factors for children with hand foot and mouth disease in Guangdong
Objective to summarize the clinical characteristics of hand foot and mouth disease (HFMD) and to explore the high risk factors of severe hand foot and mouth disease.
Methods 1204 cases of HFMD patients from April 2008 to December 2011 in our hospital were selected as the research object, including 806 cases of male (66.86%), 398 cases were female (33.14%). The age ranged from 3 months to 14 years, average 2.25 years old. This study first describes HFMD patients in July, age distribution, gender and other aspects. Then on the basis of "intestinal virus (EV71) infection diagnosis and treatment guidelines (2010 Edition) >, the patients were divided into mild HFMD cases in 1156 cases (96.01%) and severe HFMD were 48 cases (3.99%). HFMD was observed in patients with sex, age, duration of fever, rash and heat peak, time, location and rash the degree of the spirit, there is no acral temperature, runny nose, startle, convulsions, consciousness changes, difficulty in breathing, vomiting, abdominal distension, regular laboratory detection of blood routine test, liver function and myocardial enzymes, if necessary, chest X-ray, ECG, head CT or magnetic resonance imaging applications, in May 2009 the Ministry of health to develop a" hand foot and mouth disease The case with the above parameters. The questionnaire > record repeated assessment of patients'condition, clear changes in patient condition. Real time fluorescence quantitative PCR (RT-PCR) detection of enterovirus universal type (EV), type EV71 (?) CoxA16 type nucleic acid for determination of pathogens. The clinical symptoms of patients with HFMD, signs and test results were graded. With EV71 (?) CoxA16 positive HFMD patients were given the severity of the Logistic regression analysis of single factor and multi factors analysis.
Result
Analysis of 1. epidemiological data
From April 2008 to December 2011 in our hospital 1204 cases of HFMD patients, there was no significant difference in the incidence of change each year (P0.05).4 in HFMD peak appeared in the year of 4-11 months, the trough appeared in 12-3 months. 806 cases of male patients (66.94%), 398 cases of female patients (33.06%), gender ratio of 2.03:1, HFMD in each year were no statistically significant differences in gender distribution (P0.05). Through the analysis of the age distribution, the minimum age is 2 months, the maximum age of 14 years. Among them 943 patients less than 3 years (78.32%), the incidence of 3 and less than 7 years old in 235 cases (19.51%). At the age of 7 in 26 cases (2.16%).2008 years from April to December 2011 in our hospital were HFMD cases, real-time fluorescence quantitative PCR (RT-PCR) positive rate was the highest in EV, followed by EV71, CoxA16,.EV71 and CoxA16 ranked third to change each year the incidence of no significant difference (P0.05) of HFMD in each year. Patients There was no statistical difference between the severity of the disease and the distribution of sex (P0.05)
2. clinical data analysis
Analysis of the annual HFMD patients with gender, age, distribution of symptoms. In the observation of the selected indicators, age, duration of fever, heat peak, oral mucosa rash, cough, startle, change of consciousness, the spirit of difference had significant difference (P0.05); sex, (hand, foot, hip.), runny nose, convulsions, limb temperature, difficulty breathing, vomiting, no statistically significant difference (P0.05). The abdominal distension from April 2008 to December 2011 in our hospital 1204 cases of HFMD patients according to the severity of the disease is divided into mild and severe, the symptoms and the incidence of early (within 3 days) for single factor analysis. Blood routine and biochemical test results. The heating time, the buttocks rash, startle, convulsions, consciousness, spirit, acral temperature, difficulty breathing, vomiting, abdominal distension, early onset (within 3 days) Dbil values were statistically significant differences (P0.05). The general condition and symptoms, age, The time interval from onset to peak (day), heat rash, (hand, foot, mouth), cough, there were no differences statistically significant (P0.05), runny nose, laboratory index, admission check WBC, PLT, GLU, ALT, AST, Tbil, Ibil, GGT, CK, CK_MB, LDH_L, HBDH HSCRP, PT, APTT, Fg, PCT_F, no statistically significant difference (P0.05). Multivariate LR analysis method using logistic regression of the symptoms and test results, the early warning indicators of severe HFMD disease that is: poor spirit, startle, convulsions, vomiting, the incidence of early (within 3 days) WBC increased and Dbil increased.
