Asperger syndrome and the English curriculum: addressing the challenges

A major criterion for the diagnosis of Asperger syndrome is an impairment of the imagination. This article focuses on the specific difficulties that students with Asperger syndrome have with the imaginative content of the English curriculum. It examines the problems with reading and writing imaginatively of a group of students with AS in a secondary school mainstream setting. Various strategies and interventions are considered and discussed which could aid their understanding and learning in relation to the imaginative element of the English curriculum. While acknowledging that this is an area of real difficulty for these students, recommendations include: treating students with AS as individuals; using a small group setting; providing support through structured frameworks.     

Clinical and biochemical characteristics of high-intensity functional training (HIFT) and overtraining syndrome: findings from the EROS study (The EROS-HIFT)

The metabolic and hormonal consequences of high-intensity functional training regimens such as CrossFit® (CF) are unclear. Little is known about the triggers and clinical and biochemical features of CF-related overtraining syndrome (OTS). The EROS study compared endocrine and metabolic responses, and eating, social, psychological and body characteristics of OTS-affected (OTS) and healthy athletes (ATL), and non-physically active controls (NPAC). The current study is a post-hoc analysis of the CF subgroups of the EROS study, to evaluate specific characteristics of CF in ATL and OTS. Parameters were overall and pairwise compared among OTS-affected (CF-OTS) and healthy (CF-ATL) athletes that exclusively practiced CF, and NPAC. CF-ATL yielded earlier and enhanced cortisol, GH, and prolactin responses to an insulin tolerance test (ITT), increased neutrophils, lower lactate, increased testosterone, improved sleep quality, better psychological performance, increased measured-to-predicted basal metabolic rate (BMR) ratio and fat oxidation, and better hydration, when compared to NPAC. Conversely, more than 90% of the adaptive changes in CF were lost under OTS, including an attenuation of the hormonal responses to an ITT, increased estradiol, decreased testosterone, and decreased BMR and fat oxidation; the most remarkable trigger of OTS among “HIFT athletes” was the long-term low carbohydrate and calorie intake.     

Naturalistic intervention for Asperger syndrome – a case study

On the basis of their cognitive abilities, children with Asperger syndrome are attractive candidates for inclusive education and, in Australia, most are in integrated settings. However, social interaction between children with Asperger syndrome and their peers remains problematic, with the children with Asperger syndrome often being left alone despite being among or near classmates. For classroom teachers, effective interventions in terms of class management are critical to facilitate positive social interaction between these two groups of children, and case studies can tell us a great deal about what works. In practice, a combination of intervention techniques may be best, in case a single one is ineffective, and in order to take advantage of potential synergies. In this article, Serene Choi, of the School of Education at the University of Newcastle (Australia) and Timo Nieminen, of the Centre for Biophotonics and Laser Science in the Department of Physics at the University of Queensland, report a naturalistic multiple-component intervention used to develop the social skills of a boy with Asperger syndrome in a mainstream school in Australia. This combined intervention, making use of social stories, simple peer modelling and individual lessons, appears to be a practical teaching method for inclusive education.

Munchausen syndrome by proxy: A family affair

Munchausen syndrome by proxy is an unusual form of child abuse: a child presents with an illness that has been factitiously produced by a parent, typically the mother. A case of chronic illicit insulin administration to a one-year-old girl is described. Despite temporary separation of the child from the mother and long-term psychiatric intervention, factitious illnesses continued, including urine specimen contamination, laxative-induced diarrhea, suspected bladder catheterization, and suspected poisoning. Retrospective review of the medical records of the mother and two siblings demonstrated previously unrecognized evidence of factitious illnesses. The medical records contained evidence of 30 separate episodes of suspected or documented factitious illness in these four members of the same family. This unique family illustrates the significant morbidity of Munchausen syndrome by proxy and a poor response to psychiatric treatment.     

Visceral and somatic hypersensitivity,autonomic cardiovascular dysfunction and low-grade inflammation in a subset of irritable bowel syndrome patients

The pathophysiology of irritable bowel syndrome (IBS) is complex and not fully understood, so the aim of this study was to evaluate whether visceral and somatic hypersensitivity, autonomic cardiovascular dysfunction, and low-grade inflammation of the gut wall are associated with diarrhea-predominant IBS (D-IBS). Sixty-two patients with D-IBS and 20 control subjects participated in the study. Using the ascending method of limits (AML) protocol, we demonstrated that D-IBS patients had significantly lower sensory thresholds compared with healthy controls (P<0.001). Using diverse methods, especially the ischemic sensitivity test, for the first time in China, we confirmed that D-IBS patients have somatic hypersensitivity. They had a significantly higher systolic blood pressure and heart rate after a cold stimulus, indicative of autonomic cardiovascular dysfunction. Compared with the control group, D-IBS patients had a significantly higher level of calprotectin (P<0.001). We also found significant correlations between visceral and somatic hypersensitivity, visceral hypersensitivity and autonomic cardiovascular dysfunction, and somatic hypersensitivity and autonomic cardiovascular dysfunction. Our findings may provide valuable suggestions for the treatment of D-IBS.     

Two unrelated patients with rare Crigler-Najjar syndrome type I: two novel mutations and a patient with loss of heterozygosity of UGT1A1 gene

Crigler-Najjar syndrome type I (CN-I) is the most severe type of hereditary unconjugated hyperbilirubinemia. It is caused by homozygous or compound heterozygous mutations of the UDP-glycuronosyltransferase gene (UGT1A1) on chromosome 2q37. Two patients clinically diagnosed with CN-I were examined in this paper. We sequenced five exons and their flanking sequences, specifically the promoter region of UGT1A1, of the two patients and their parents. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to determine the UGT1A1 gene copy number of one patient. In patient A, two mutations, c.239_245delCTGTGCC (p.Pro80HisfsX6; had not been reported previously) and c.1156G>T (p.Val386Phe), were identified. In patient B, we found that this patient had lost heterozygosity of the UGT1A1 gene by inheriting a deletion of one allele, and had a novel mutation c.1253delT (p.Met418ArgfsX5) in the other allele. In summary, we detected three UGT1A1 mutations in two CN-I patients: c.239_245delCTGTGCC (p.Pro80HisfsX6), c.1253delT (p.Met418ArgfsX5), and c.1156G>T (p.Val386Phe). The former two mutations are pathogenic; however, the pathogenic mechanism of c.1156G>T (p.Val386Phe) is unknown.
