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

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.

Effect of midazolam combined with fentanyl as adjuvant therapy on inflammatory factors and biochemical indexes in children with serious hand-foot-mouth disease with mechanical ventilation / 中华传染病杂志

Objective To investigate the effect of midazolam combined with fentanyl as adjuvant therapy on inflammatory factors and biochemical indexes in children with serious hand-foot-mouth disease with mechanical ventilation .Methods One hundred and thirty children with serious hand-foot-mouth disease treated with mechanical ventilation were selected at Maternal and Child Health Care Hospital from January 2010 to January 2014 . The patients were divided into two groups according to the treatment regimen :58 cases treated with midazolam for sedation and analgesia as control group and 72 cases treated with midazolam combined with fentanyl as observation group . Inflammatory factors (interleukin-6 , interferon-γ ,high-sensitivity C-reactive protein and tumor necrosis factor-α) and biochemical indices (albumin ,alanine transaminase [ALT] ,aspartate transaminase [AST] ,alkaline phosphatase ,glutamate transpeptidase [γ-GT] and fasting blood glucose) before drug exposure and on withdrawal were compared between two groups .Adverse reactions were analyzed in the two groups .Continuous variables were compared using two-sample t-test , while categorical variables were compared using chi-square test . Results Interleukin-6 ,interferon-γ, high sensitive C reactive protein and tumor necrosis factor-α on withdrawal decreased significantly in both groups than those before drug exposure (all P0 .05) .However ,in observation group ,fasting blood glucose level decreased significantly on drug withdrawal compared with that before drug exposure ([5 .17 ± 0 .28] vs [10 .31 ± 1 .39] mmol/L ,t=46 .237 ,P=0 .000) ,and that was also lower than control group ([5 .17 ± 0 .28] vs [5 .85 ± 0 .34] mmol/L ,t=4 .372 ,P=0 .000) .Incidence of adverse reactions in observation group was significantly lower than control group (15 .3% vs 32 .8% ,χ2=4 .707 ,P=0 .030) . Conclusions Midazolam combined with fentanyl as adjuvant therapy is helpful to improve blood glucose , stabilize biochemical indices and reduce inflammation factor secretions in children with serious hand-foot-mouth disease with mechanical ventilation .This therapy is safe and worthy of clinical use .

Severe hand foot and mouth disease in 68 children with brainstem encephalitis / 中国小儿急救医学

Objective To explore the clinical features and risk factors of children with severe hand foot and mouth disease (HFMD).Methods The clinical data of 68 children with HFMD associated with brainstem encephalitis were analysed retrospectively from Apr to Sep 2010.Results Among the 68 cases,63cases(92.6％ ) were younger than 3 years.The major symptoms and physical signs of 68 cases included rash (68 cases,100％ ),fever (68 cases,100％ ),fatigue (68 cases,100％ ),irritability (65 cases,95.6％ ),somnolence (42 cases,61.8％ ),vomiting (28 cases,41.2％ ),limb tremor (23 cases,33.8％ ),tendon reflexe hyperactivity (60 cases,88.2％ ),tachypnea or respiratory rhythm abnormality (63 cases,92.6％ ),tachycardia (65 cases,95.6％ ),and hypertension (54 cases,79.4％ ).Twenty-five cases (36.8％,25/68 ) had leucocytosis ( ＞ 12 × 109/L ),and 19 cases ( 27.9％,19/68 ) had hyperglycaemia.X-ray appearances:patchy and pathy shadows in single or bilateral pulmonary were seen in 46 cases( 67.6％,46/68 ).Forty-eight cases were examined by MRI,eight cases displayed ischemic lesions or demyelination.Spinal cord MRI was performed in 3 cases with flaccid paralysis,which showed demyelination.The etiology indicated that 38 cases ( 55.9％,38/68 ) were infected by enterovirus 71,25 cases( 36.8％,25/68 ) were infected by other enterovirus,5 cases (7.3％,5/68) were negative.All the cases were treated by mechanical ventilation with tracheal intubation,in whom 63 cases recovered well,4 cases improved,and 1 case gave up to die.Conclusion Ages ＜ 3 years,enterovirus 71 infection,continual fever,fatigue,somnolence,irdtability,vomiting,limb tremor,tendon reflexes hyperactivity,tachypnea or respiratory rhythm abnormality,tachycardia and hypertension are the high risks of critically ill children associated with severe HFMD.To reduce the fatality rate of HFMD,it is crucial to early judge the high risk factors,and take mechanical ventilations earlier.

Effect Of mechanical ventilation with the least delay on the severe cases of hand-foot-mouth disease / 中国小儿急救医学

objective To explore the indication of mechanical ventilation and evaluate the effects of mechanical ventilation with the least delay on the Severe cases of hand-foot-mouth disease(HFMD).Methods Retrospective cohort study was conducted among the severe HFMD cases(n=66)admitted to pediatric intensive care unit(PICU)between July 2008 and september 2009.Sixty-six cases were divided into two groups:42 cases(group A,July 5 to October 31,2008)were ventilated with the common mechanical ventilation,24 cases(group B,April 21 to september 30,2009)were ventilated at least delay when the symptoms of neurogenic pulmonary edema appeared.Then the diffcrences on the survival rate and the mortality in the group A and group B were investigated.Results Twenty out of 42 patients died(47.6%),eighteen were cured(42.6%) and four showed improved signs(9.5%)in group A.Twenty-two out of 24 patients were cured(91.7%),two showed improved signs(8.3%)and no death in group B.The clinical effect of group B was much better tllan group A(P<0.001).Conclusion Early mechanical ventilation would improve the survival rate and decrease the mortality of severe hand-foot-mouth disease.
