The escape is the practice that changes a person into a fugitive. Such escape might have been induced by economic, political and/or social reasons. Generally, two terms were used to identify people who ran away from their habitat: hapirum and munnabtum. In this paper, I will follow the viewpoints of Bottéro and Rowton to denote that the former were social rootless people while the latteraccording to Buccellatiwere politically displaced individuals. These stances do not agree with Durand’s perspective about such social actors located within the political scenario at Mari. This author defines and re-defines them throughout several papers to finally understand the hapirum as political adversaries and the munnabtum as emigrants due to specific situations. Based on the analysis of the approaches of all the mentioned authors, we get to understand that the term hapirum would explain the situation of emigrant/immigrant people. The alleged political opposition of these social actors was not the source of their displacement but one of the consequences resulted from it. Thereafter, the political aspect that would sheathe the hapirum would be a result of their need and not the motive. Conversely, the term munnabtum would actually imply a political bias that could be traced out by finding them isolated or hunted individually by the political power. Thus, the aim of this paper is to set out the complexity that the translation of certain terms involves and, considering the cases 1 Una primera versión de este trabajo fue presentada en el Workshop “Convegno internazionale.

Objective: Tuberous sclerosis complex (TSC) is a multisystem disorder characterized by the formation of hamartoma in multiple organ systems of the body. However, without a well-established cooperative system involving related departments, some organ lesions might be overlooked until symptoms appear or even until the disorder progresses. Therefore, the purpose of this study is to investigate the current status of follow-ups in the TSC patients in the Department of Child Neurology at Okayama University Medical Hospital. Methods: We performed a retrospective chart review of 38 patients with TSC who visited our hospital at least twice between January 2005 and December 2014. Patients were between 3 years and 48 years of age at their latest visit. We divided the patients into a child group and an adult group, and investigated the patients’ follow-up data while focusing on the various multiorgan systems. Results: The follow-ups were well conducted in the child group in terms of every organ. In the adult group, neuroimaging tests were unsatisfactorily performed. The kidney has not been examined in seven patients more than five years even though these patients all had kidney lesions. The lung was not been examined in 7 out of 14 female patients over 18 years of age who are most at risk for lymphangioleiomyomatosis (LAM). In 12 out of 18 child patients, echocardiograms were performed every few years, while electrocardiograms to assess underlying conduction defects were rarely performed in either age group. Conclusions: In Europe, guidelines for the management of TSC have been well established. However, in our hospital, the multiorgan system follow-up is not satisfactorily performed especially in adult patients. We decided the establishment of a TSC board in our hospital for the management of this multiorgan disorder.
We report the case of a 14-month-old girl with Dravet syndrome carrying a splice-site mutation of c. 1170+1G>A on neuronal sodium channel alpha 1 subunit (SCN1A). 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. Therefore, clinicians should carefully manage prolonged febrile seizures in patients with Dravet syndrome.
Objective: Anti-epileptic drugs, such as carbamazepine (CBZ) or phenytoin, may induce hypothyroidism in epilepsy patients. 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.
We report the case of a patient born with extreme muscle hypotonia, respiratory failure, and slightly elevated serum levels of lactic acid. Histochemical examination and mitochondrial respiratory chain enzyme activities of a muscle biopsy specimen revealed reduced activities of complexes Ⅰ, Ⅲ, and Ⅳ, diagnostic of mitochondrial respiratory chain disorder. Hypertrophic cardiomyopathy developed as a complication and additional therapy was administered at 3 months after birth. He was able to be discharged to home on applied home mechanical ventilation with tracheotomy at 1 year old. The patient survived until 4 years and 10 months of age, upon which he died of bronchitis. Early-onset mitochondrial respiratory chain disorder shows very poor prognosis and long-term survival has not been reported. Prompt assessment of mitochondrial respiratory chain enzyme activities is necessary for the diagnosis of congenital nonspecific multiple-organ failure, and early intervention may achieve better prognosis for mitochondrial respiratory chain disorder.
An 11-year-old boy with Lesch-Nyhan syndrome (LNS) had persistently injured himself by biting his lips and buccal mucosa since infancy. Risperidone was only partially effective in suppressing this behavior. Oral administration of S-adenosylmethionine (SAMe), involving increasing the dose from 400 mg to 1 g, resulted in the amelioration of self-injurious behavior and anxiety as well as marked improvement in his self-esteem, performance at school, and friendships. No adverse effects were noted. SAMe may have a favorable effect on symptoms of LNS by activating monoaminergic pathways and/or increasing the adenosine pool in the salvage pathway of guanosine monophosphate synthesis. Defects in these pathways have been essentially implicated in the neurological pathophysiology of LNS.
CDKL5 gene mutations are the cause of symptomatic infantile epilepsy in some patients. Such patients present with partial seizures and characteristic hand movements that are often observed in patients with Rett syndrome. This clinical entity has recently been recognized as CDKL5 disorder. In a girl with CDKL5 disorder, who had been treated with combinatory therapy using many anti-epileptic drugs, we were able to control the seizures with valproate monotherapy. As a result of the monotherapy, the patient’s seizures ameliorated temporarily and her quality of life improved. Some patients show improvement in seizures during the natural course of CDKL5 disorder. Therefore, there is a possibility that this was also the case in our patient. However, the patient and her family were satisfied with the improvement in quality of life after the withdrawal of the multi-drug combinatory therapy. Thus, it is important to select the best therapy for patients with intractable epilepsy through long term follow-up.
A 3-month-old male was brought to our hospital due to fever, poor sucking, and a bulging anterior fontanel. His general condition was poor. Analysis of the cerebrospinal fluid (CSF) showed increases in the cell count (8/μl) and the polymorphonuclear leukocyte count (2/μl) but normal sugar (66 mg/dl) and protein (28 mg/dl) levels. A CSF smear showed no bacterial cells. The administration of antibacterial drugs was initiated, and head MRI was performed on the next day. Plain images revealed no abnormalities. However, contrast-enhanced fluid-attenuated inversion recovery (FLAIR) MRI showed clear contrast enhancement along the brain surface in the meninges of the left and right frontal and left parietal lobes and fluid retention accompanied by contrast enhancement in a part of the adjacent subdural space. These findings could be confirmed only by contrast-enhanced FLAIR MRI. A diagnosis of bacterial meningitis with an unknown cause was made, and the administration of 2 antibacterial drugs was continued. MRI on day 8 of the illness showed the disappearance of contrast enhancement, and plain FLAIR also facilitated a diagnosis of a subdural hygroma. The treatment was effective. At present, the patient is 1 year and 6 months old without sequelae. The diagnosis of bacterial meningitis in infants is difficult based on only symptoms. In its early stage with few abnormal findings in the CSF, diagnosis is sometimes difficult. Antibacterial drug administration should be immediately initiated. However, definite findings are necessary for the continuation of large amounts of antibacterial drugs. Contrast-enhanced FLAIR allows the sensitive visualization of meningeal inflammation and is useful as a complementary diagnostic method for meningitis. In addition, this technique can reveal marked inflammatory lesions such as a subdural hygroma in the early stage, providing information useful for making a diagnosis of bacterial meningitis.
Objective: The objective of this study was to investigate the trends in the prevalence and characteristics of unilateral spastic cerebral palsy among children born between 1988 and 2007 in Okinawa, Japan. 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. Conclusion: We found a trend for an increased prevalence of unilateral spastic cerebral palsy in periodⅡ. However, the cause of this increase is as yet unknown.
To evaluate the diagnostic value of SPECT (single photon emission computed tomography) brain blood flow imaging for patients with non-herpetic acute limbic encephalitis (NHALE). A retrospective review of three patients who had clinical symptoms compatible to NHALE and were positive for anti-N-methyl-d-aspartate-type glutamate receptor (GluRε2) antibody. The patients consisted of a 6-year-old female, a 10-year-old female and a 13-year-old male, all of whom had limbic symptoms and were anti-GluRε2 antibody-positive. In all cases, brain MRI failed to detect any abnormality, but SPECT brain blood flow imaging was able to detect blood flow changes. All three cases showed some abnormality in their brain waves, and one of them also developed epilepsy. SPECT brain blood flow imaging may therefore be helpful for diagnosing NHALE which can lead to the development of either epilepsy or cognitive impairment.
A 6-year-old girl experienced nausea and vomiting for 3 weeks and double vision for 1 week prior to her first visit to our hospital. She had bilateral ophthalmoplegia from sixth cranial nerve palsy and papilledema. Her brain MRI showed normal brain parenchyma. The lumbar cerebrospinal fluid (CSF) opening pressure was 1000 mm of water measured with normal CSF contents. From these findings, she was diagnosed with idiopathic intracranial hypertension (IIH). Initial lumbar puncture (LP) immediately improved her symptoms, but acetazolamide, a first line drug for the treatment of IIH, failed to maintain the remission, and three more periodical LP were required to relieve her symptoms every 2 weeks. After the fourth LP, acetazolamide was switched to a second line drug for IIH, topiramate, which was found to be highly effective in controlling IIH in a short time period. The long process of IIH causes vision loss, therefore, its prompt treatment is vital. In cases refractory to medical treatment, surgical treatments such as CSF shunt are considered. Acetazolamide is used in most IIH cases after the initial diagnosis, but in this case, it was ineffective, and topiramate was highly effective. Both acetazolamide and topiramate are inhibitors of carbonic anhydrase isoforms involved in CSF secretion. Inhibition of choroid plexus carbonic anhydrase by these drugs leads to decreased CSF secretion and the consequent control of intracranial pressure. Higher isoform specificity and increased lipophilic nature of topiramate, which are advantageous for passing through the blood brain barrier, may be the reasons for better activity than acetazolamide, at least in the present case. Topiramate might be effective and should be considered for refractory IIH cases before surgical treatments.
We describe the case of a 15-year-old male with early juvenile type GM2 gangliosidosis. He first manifested with progressive clumsiness in his extremities at the age of 1.5 years, followed by motor regression. Intellectual disability became evident as late as age 6 years. This discrepancy along with rapid motor deterioration after varicella infection, lack of startle response or macrocephaly, and paucity of myoclonus were thought to be characteristic of juvenile GM2 gangliosidosis. In contrast to the cerebellar atrophy as the initial finding in usual juvenile GM2 gangliosidosis, magnetic resonance imaging revealed initially cerebral, and subsequently cerebellar, progressive atrophy. Autistic behavioral problems, including phonophobia, during intellectual regression in this patient was also unusual in juvenile GM2 gangliosidosis. Thus, recognition of these features would prompt proper diagnosis and insights into the pathomechanisms of GM2 gangliosidosis.
A male infant suffered from partial seizures at four months of age, and developed West syndrome at eight months of age. ACTH therapy was effective for the West syndrome. However, partial seizures recurred at 14 months of age, which could not be sufficiently controlled with an anti-epileptic drug. A characteristic facial appearance, great toe abnormalities, and developmental retardation were noted. An interstitial deletion of 2q was detected by chromosomal G-banding and array comparative genomic hybridization (CGH) confirmed the deletion as arr 2q24.3q31.3 (166,303,447-180,982.972) ×1 (build19). He presented with clinical findings similar to those of the recently defined 2q31.1 deletion syndrome. The deletion extended to the SCN1A gene, a gene responsible for Dravet syndrome, mapped to the 2q24.3 region. No deletion was noted in the adjacent SCN2A gene. Thus, for interstitial deletions, detailed breakpoints should be identified by array CGH. The frequency of epilepsy varies with deletion ranges in the 2q24-q31 region, suggesting that deletions in the SCN1A gene deletion, as well as in the 2q31.1 region, are involved in the development of West syndrome.
Patients with spinal muscular atrophy type Ⅰ (SMA Ⅰ) with the onset before the age of 3 months are considered as severe form of SMA Ⅰ (severe SMA Ⅰ) and have poor prognosis. Here, we report the efficacy of non-invasive positive pressure ventilation (NPPV) in a patient with severe SMA Ⅰ. She was born with generalized hypotonia and feeding difficulties, and had SMN1 gene mutations (the deletion of exons 7 and 8). At 1 month of age, she was intubated because of respiratory failure due to a respiratory tract infection, and extubation proved difficult. Her parents decided that NPPV and a mechanical in-exsufflator (MI-E) should be used for respiratory management rather than a tracheotomy. The NPPV improved her peripheral coldness, cold sweats, chest wall movement, and heart rate and enabled her to sleep well. At 1 year and 2 months, chest computed tomography revealed mild pneumonia and did not show any atelectasis. The NPPV facilitated discharge, and the patient had a good quality of life (QOL) from the point of view of voice production, the ability to move easily, the simplicity of bathing, and the low level of discomfort she experienced. However, she suffered repeated episodes of aspiration pneumonia and airway obstruction (by sputum) after 11 months of age. Thereafter, she required continuous NPPV and high-span inspiratory positive airway pressure (21 cmH2O). At 1 year and 4 months, she died of respiratory failure at home. As her bulbar weakness worsened, respiratory management with NPPV became difficult. However, the long-term use of NPPV together with high-span positive inspiratory pressure plus positive end-expiratory pressure, and a high-pressure MI-E at an early age might improve respiratory management outcomes and patient prognosis. In our case, NPPV was effective at improving ventilation and preventing atelectasis and helped to provide the patient with a good QOL.
We report a 9-year-old girl with Sturge-Weber syndrome (SWS) type III, whose motor function deteriorated after an episode of febrile status epilepticus. The patient had leptomeningeal angiomas in the left temporal, occipital, and parietal lobes. Complex partial seizures, which started at 8 months, were controlled by antiepileptic medications. At 9 years of age, she developed irreversible ischemic lesions in the left temporal and occipital regions after the febrile status epilepticus and her motor function deteriorated. In addition to antiepileptic medications, aspirin therapy was started.SWS type III is a rare disorder characterized by leptomeningeal angiomatosis without facial nevus. In addition to the chronic ischemia in the affected cortex, epileptic seizures result in a phased progression of ischemia in SWS. Although the patient’s complex partial seizures had been well-controlled, a single episode of febrile status epilepticus resulted in permanent brain lesions. The impairment of appropriate hemodynamic response to status epilepticus, together with venous hypertension in the affected side in SWS may have caused the cerebral infarction in our case. Seizure control is crucial to improving the neurological prognosis of SWS.
Even though evidence-based clinical guidelines are useful for the management of common diseases, there are several problems in applying such guidelines to patients with rare diseases. First, there are few references providing high-level evidence pertaining to such diseases, and randomized control as well as large cohort studies are lacking. Most grades of recommendation are “suggest” rather than “recommend” or, often, are based on “expert opinion”. Juvenile myasthenia gravis (MG) is a rare disease and has mainly been reported in East Asia. In 2014, evidence-based clinical guidelines for MG diagnosis and treatment were published in Japan. Since references were scarce, these guidelines were also based on expert opinions such as those of a few institutes or specialists who had gathered most of the patients in Japan. The guidelines might be of limited usefulness for general pediatricians or pediatric neurologists with no MG experience, and we should be aware of strengths and pitfalls when applying such guidelines. For example, while knowing when to start steroid administration or the appropriate steroid dose is feasible, the optimal timing of switching from an anti-cholinesterase drug to a steroid or adding an anti-inflammatory drug and how to decrease or stop steroid administration cannot be ascertained from the guidelines. The lack of references with high-level evidence makes the guidelines difficult to apply, since this would be the information most desired by clinicians. Another problem is that a recommendation may easily be reversed if opposing results are obtained in a single study of a rare disease. Thymectomy was recognized as not being beneficial for MG without thymoma but one recent study reversed this recommendation in the guidelines. Herein, we discuss pitfalls in applying diagnostic and treatment guidelines in patients with juvenile MG.
