Clinical study of hand foot and month disease with acute flaccid paralysis / 中国小儿急救医学

ABSTRACT

Objective To investigate the epidemiological and clinical characteristics and prognosis of 31 children with hand foot and mouth disease(HFMD) complicated with acute flaccid paralysis(AFP).Methods Thirty-one HFMD children complicated with AFP served as study objective,who were admitted to Tangshan Maternity and Children Health Hospital from Jun 2011 to Dec 2014.The clinical manifestations and follow-up outcomes of 31 children with HFMD followed by AFP were retrospectively reviewed.Results Participants in this study consisted of 31 children(16 males,15 females,age from 3 months to 9 years) who met the criteria for HFMD with AFP.Among the 31 cases,27(87.1％)cases were less than 3 years old and 29(93.5％) cases were from countryside.Eleven cases (35.5％)were infected by enterovirus 71,1 case (3.2％) was infected with coxsackieviruses A16 and 19 cases(61.3％) were infected by other enteroviruses.AFP developed(7.1 ±2.9) days after the onset of fever and progressed to maximum severity within 1-2 days.All of the cases presented with fever and skin rash,38.7％ cases presented with limbs tremor and 87.1％ cases presented with startle and skip.Besides AFP of limbs, 100％ cases complicated with encephalitis.Thirty-one cases showed poliomyelitis-like syndrome(20 cases with one flaccid limb,5 cases with lower limbs,4 cases with upper limbs and 2 cases with left hemiplegia).In these cases, the muscle power varied from level 0 to level 4.The muscle strengthen and muscle tone in 21 patients were recovered within 2 weeks,and the other cases showed recovery 2 to 3 weeks later.After four weeks, the muscle strengthen in 19 cases recovered to 5 level(10 cases with single lower limb,5 cases with single upper limb,3 cases with two lower limbs and 1 case with two upper limbs).Conclusion HFMD complicated with AFP most commonly occurs in children aged less than 3 years old.The majority of cases were from countryside.Enterovirus 71 is still relatively common pathogen.All the 31 cases complicated with encephalitis.Cases clinically presented one flaccid limb, lower limbs, upper limbs and hemiplegia.AFP may be to some degree reversible in HFMD cases.In most cases described here, paralysis occurred in a single lower extremity and recovered more rapidly than those with two fimbs affected or with single upper extremity impairment.
