We assessed thyroid function of chronic patients with severe motor and intellectual disabilities (SMID) in our hospital. Methods: We examined thyroid-stimulating hormone (TSH), free thyroxine (fT4), and free thyronine (fT3) in 73 patients with SMID (47 men and 26 women, average age 48.4 years, range 30-68 years) without thyroid hormone supplement therapy. We determined the relationship between the thyroid function of patients taking the anti-epileptic drugs CBZ, valproate (VPA), and phenobarbital, other medications including anti-psychotic drugs, and treatments without anti-epileptic or anti-psychotic drugs. Results: TSH levels were not significantly different between the groups taking CBZ (CBZ+med), other anti-epileptic drugs or anti-psychotic drugs (CBZ-med), and only medications without anti-epileptic or anti-psychotic drugs (Non-med). The CBZ+med group had significantly lower fT4 levels than the CBZ-med or Non-med groups. There was a negative correlation between thyroid function level and the phenobarbital groups. TSH levels of the VPA+med group were significantly higher than VPA-med and Non-med group; fT3 and fT4 levels were not significantly different. Conclusions: Our results indicate that hypothyroidism may be present in patients with SMID taking anti-epileptic drugs. This suggests it is important to regularly measure thyroid function in patients with SMID taking anti-epileptic drugs, especially CBZ.</p>","PeriodicalId":39367,"journal":{"name":"No To Hattatsu","volume":"49 1","pages":"19-24"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36315749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

She had a history of recurrent febrile or afebrile seizures since 4 months of age and developed acute encephalopathy due to infection with human herpesvirus-6, which presented with high grade fever, severe consciousness disturbances, and prolonged and clustered seizures. Electroencephalography showed a generalized slow activity. Intensive treatments, including mechanical ventilation, continuous thiopental infusion, and high-dose steroid therapy were initiated, and she gradually recovered. During the recovery phase, choreoathetosis-like involuntary movements appeared on the face and limbs, which were treated successfully with haloperidol. MRI findings during the acute phase were normal; however, diffuse cerebral atrophy became evident during the recovery phase. Single photon emission computed tomography (SPECT) of the brain revealed decreased cerebral perfusion over bilateral frontal and temporal lobes; however, perfusion of the occipital lobes, basal ganglia, and cerebellum remained normal. The patient showed serious developmental regression at discharge, with the loss of head control and meaningful words. Patient’s clinical course and the findings of SPECT resembled those of acute encephalopathy with biphasic seizures and late reduced diffusion (AESD), with the exception of lack of reduced diffusion of the subcortical white matter on the acute phase MRI and the prolonged and severe clinical symptoms. It has been reported that patients with Dravet syndrome are prone to complications, including various types of acute encephalopathies.

Method: We conducted a surveillance of children with cerebral palsy using the local cerebral palsy registration system. For analysis purposes, the study was divided into two periods: periodⅠ (from 1988 to 1997) and periodⅡ (from 1998 to 2007). We performed a chi-squared test and Poisson regression analysis. Result: We observed a significant trend for an increased prevalence of unilateral spastic cerebral palsy in periodⅡ (p<0.01). The number of children with unilateral spastic cerebral palsy who were born with birth weights of 1500 g or more and/or a gestational age of 32 weeks or more was increased in periodⅡ. In addition, brain magnetic resonance imaging and computed tomography scans showed that porencephaly and periventricular white matter damage were common findings in preterm children of gestational age less than 31 weeks in period II. The most frequently observed neuroimaging feature in children with a gestational age of over 32 weeks was brain infarction.

To minimize potential adverse effects, VGB was given to the patients for limited 6 months with titration from 30 mg/kg/day as an initial dose. Results: Main seizure types were classified into spasms (n=10) or tonic seizures (n=7). Seizure reduction was positively associated with seizure type of infantile spasms, lower maximum dosage, younger age on VGB administration, and earlier VGB treatment after the diagnosis. Seizure type of infantile spasm was an independent favorable predictor and also associated with long-term seizure reduction.
