OBJECTIVE:
To explore the clinical characteristics and genetic etiology for two children with Neurodevelopmental disorder with hypotonia, stereotypic hand movements, and impaired language (MEDHSIL).
METHODS:
Two children who had visited the Ningbo Women and Children's Hospital on October 15, 2021 were selected as the study subjects. Whole exome sequencing (WES) was carried out for both patients. Candidate variants were verified by Sanger sequencing of their family members.
RESULTS:
The two children were respectively found to harbor a heterozygous c.138delC (p.Ile47Serfs*42) variant and a c.833del (p.L278*) variant of the MEF2C gene. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), both variants were predicted to be pathogenic (PVS1+PS2+PM2_Supporting).
CONCLUSION
The c.138delC and c.833del variants of the MEF2C gene probably underlay the pathogenesis of MEDHSIL in the two children. Above findings have enriched the mutational spectrum of the MEF2C gene and enabled genetic counseling for their families.

3.Clinical and genetic analysis of a child with maternal uniparental disomy of chromosome 20.
Chinese Journal of Medical Genetics 2023;40(11):1420-1424
OBJECTIVE:
To explore the clinical and genetic characteristics of a boy with isolated maternal uniparental disomy of chromosome 20 [UPD(20)mat].
METHODS:
A child who was admitted to the Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology on April 8,2021. was selected as the study subject. Phenotypic and endocrinological findings of the child were retrospectively analyzed. Whole exome sequencing (WES) and methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) were carried out for detecting the UPD sequences and copy number variations. Both of his parents were verified by Sanger sequencing. Relevant literature was systematically reviewed.
RESULTS:
The child, a 3-year-and-8-month-old boy born to a 41-year-old mother by Cesarean delivery at 36+2 gestational weeks due to oligohydramia, had a birth weight of 2 300 g and length of 46 cm. He was admitted to the NICU for feeding difficulties which had persisted despite of clinical management. At the age of 3.75, he had a height of 92.5 cm (< 3rd percentile; 25th ~ 50th percentile at 2.5 years) and a weight of 10.8 kg (< 3rd percentile; 50th percentile at 15 months). He had also presented with growth retardation, short stature, attention deficit and hyperactivity disorder (ADHD), mild mental retardation, and speech and language development disorders. He had simian creases in both hands but no additional dysmorphic signs, and his motor development was normal. Serum insulin, thyroid-stimulating hormone, and insulin growth factor binding protein 3 levels were within the normal ranges, though insulin growth factor-1 (IGF-1) was slightly decreased. Since that time he had continuously used atomoxetine hydrochloride capsules to control his ADHD. WES and MS-MLPA revealed the existence of UPD (20)mat.
CONCLUSION
The UPD(20)mat syndrome is characterized by feeding difficulties, growth retardation and short stature. The child in our case has been accompanied by ADHD and speech and language development disorders, which required long-term treatment. For women with advanced maternal age and suggestive phenotypes, genetic testing and counseling should be conducted.

In this paper, we propose a multi-scale mel domain feature map extraction algorithm to solve the problem that the speech recognition rate of dysarthria is difficult to improve. We used the empirical mode decomposition method to decompose speech signals and extracted Fbank features and their first-order differences for each of the three effective components to construct a new feature map, which could capture details in the frequency domain. Secondly, due to the problems of effective feature loss and high computational complexity in the training process of single channel neural network, we proposed a speech recognition network model in this paper. Finally, training and decoding were performed on the public UA-Speech dataset. The experimental results showed that the accuracy of the speech recognition model of this method reached 92.77%. Therefore, the algorithm proposed in this paper can effectively improve the speech recognition rate of dysarthria.

INTRODUCTION:
The National Institutes of Health Stroke Scale (NIHSS), originally designed in the United States of America, contains items on dysphasia and dysarthria that are deemed culturally unsuitable for the Singapore context. We compared the error rates of dysphasia objects, dysphasia phrases and dysarthria words between the original and alternative items in a cohort of Singaporean subjects without dysphasia or dysarthria.
METHODS:
In this prospective study, 140 English-speaking Singaporean subjects without impairments of dysphasia or dysarthria had an assessment of NIHSS items 9 and 10 using the original and alternative items. Paired analyses were conducted for comparison of error rates.
RESULTS:
The error rates were high for four original dysphasia objects (Hammock: 62.9%, Cactus: 38.6%, Feather: 23.6%, Glove: 20.7%) and significantly lower for alternative items (Snail: 5%, Horse: 1.4%, Hanger: 1.4%, Car: 0%) (P < 0.001). For dysphasia phrases and dysarthria words, the error rates were low and there were no differences in error rates between the original and alternative items.
CONCLUSION
There are cultural issues with several dysphasia objects in the original NIHSS as evidenced by the high error rates, which were lowered with more culturally suitable alternatives. This study formed a basis to derive a more suitable version of the NIHSS for English-speaking subjects in Singapore.

Objective:
As part of the thrust towards Universal Health Care, the Philippines has enhanced health insurance coverage for rehabilitation with recent introductions of benefits for disabilities in children, prostheses, and orthoses. The project aimed to develop a functionality-based framework to guide comprehensive benefits for rehabilitation services for adult Filipinos.
Methods:
Scoping review was conducted to identify common rehabilitation conditions, frameworks for clinical assessment, and essential services for rehabilitation. Key informant interviews and focus group discussions were conducted with targeted rehabilitation service providers and experts to validate the information collected. A unified pathway of care and essential services for the provision of rehabilitation medicine services was developed through triangulation. The study was conducted from October 2018 to September 2019, with activities done in Metro Manila.
Results:
The results summarized treatment pathways for four major disease categories: neurologic, musculoskeletal, chronic pain, and activities of daily living/ cardiopulmonary. Impairments were identified reflecting the principles from the International Classification of Function. Disabilities were categorized based on function: mobility, self-care, cognitive-behavioral, and communication. A unified care pathway was developed to harmonize rehabilitation assessment, management, and care. A framework to simplify financial coverage was likewise provided. The extent of management (e.g., duration of therapy) depends on the severity of the disability classified as mild, moderate, or severe. Based on this classification, essential management modalities included physiatry interventions, medications, and rehabilitation sessions, supported by outcomes evaluation.
Conclusion
A framework is proposed to guide the design and implementation of benefits and health insurance coverage. Awareness and application of this approach among rehabilitation practitioners and health facilities are essential steps for successful uptake and implementation of the upcoming expansion in PhilHealth coverage.

Chinese Journal of Medical Genetics 2022;39(12):1385-1389
OBJECTIVE:
To explore the genetic etiology for a child featuring mental retardation and speech delay.
METHODS:
Clinical data of the child was collected. DNA was extracted from peripheral blood samples of the child and members of his pedigree. Whole exome sequencing was carried out for the child, and candidate variants were verified by Sanger sequencing. Prenatal diagnosis was provided for his mother upon her subsequent pregnancy.
RESULTS:
The child has mainly featured mental retardation, speech delay, ptosis, strabismus, photophobia, hyperactivity, and irritability. Whole exome sequencing revealed that he has harbored a pathogenic heterozygous variant of the KAT6A gene, namely c.5314dupA (p.Ser1772fs*20), which was not detected in either of his parents. The child was diagnosed with Arboleda-Tham syndrome. The child was also found to harbor a hemizygous c.56T>G (p.Leu19Trp) variant of the AIFM1 gene, for which his mother was heterozygous and his phenotypically normal maternal grandfather was hemizygous. Pathogenicity was excluded. Prenatal diagnosis has excluded the c.5314dupA variant of the KAT6A gene in the fetus.
CONCLUSION
The heterozygous c.5314dupA (p.Ser1772fs*20) variant of the KAT6A gene probably underlay the Arboleda-Tham syndrome in this child. Above finding has enabled genetic counseling and prenatal diagnosis for this pedigree.

Chinese Journal of Contemporary Pediatrics 2021;23(2):148-152
OBJECTIVE:
To study the intellectual characteristics of children with attention deficit hyperactivity disorder (ADHD) and developmental dyslexia (DD).
METHODS:
A total of 55 children with ADHD and DD (ADHD+DD group), 150 children with ADHD alone (ADHD group), and 22 children with DD alone (DD group) were enrolled as subjects. Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) was used to evaluate and compare intellectual characteristics among the three groups.
RESULTS:
There were significant differences in the scores of full-scale intelligence quotient (FSIQ), verbal comprehension index, perceptual reasoning index, and working memory index among the three groups (
CONCLUSIONS
Compared with the children with ADHD alone, the children with ADHD and DD have more severe impairment of FSIQ, verbal comprehension, perceptual reasoning, and working memory, and therefore, it is suggested to enhance the training on similarities, vocabulary, matrix reasoning, picture concepts, and recitation for children with ADHD and DD in clinical practice.

OBJECTIVE:
To compare the clinical efficacy between scalp acupuncture electrical stimulation and routine scalp acupuncture for motor aphasia in subacute stage of cerebral infarction.
METHODS:
A total of 54 patients with motor aphasia in subacute stage of cerebral infarction were randomly divided into an observation group (27 cases, 1 case dropped off) and a control group (27 cases, 2 cases dropped off ). Both groups were treated with routine medication and language training. In the observation group, scalp acupuncture was given at bilateral lower 2/5 of the parietal and temporal anterior oblique line and temporal frontline; after the arrival of
RESULTS:
After treatment, the scores of listening comprehension, retelling, naming, spontaneous conversation and BDAE grade in the two groups were improved compared with those before treatment (
CONCLUSION
The scalp acupuncture electrical stimulation could improve cerebral circulation, activate specific functional areas of cerebral cortex, and promote the reconstruction and recovery of brain language function. Its curative effect is better than conventional scalp acupuncture.

Chinese Journal of Medical Genetics 2021;38(10):933-936
OBJECTIVE:
To describe a family with intellectual developmental disorder with autism and speech delay (IDDAS) caused by a splice variant of TBR1 gene.
METHODS:
A pregnant women with mental retardation, who also had a family history of mental retardation, was admitted to Prenatal Diagnosis Center of WanBei Coal and Electricity Group General Hospital Corporation in April 2019. Molecular genetic tests were performed on the pregnant women and ten other family members to analyze the pathogenic genotype. Functional assays of the pathogenic variant was carried out by minigene technology. With the determination of the genotype, prenatal diagnosis was carried out by amniotic fluid sampling.
RESULTS:
Through whole exome sequencing, a novel splicing variant (c.1129-1G>C) was identified in the TBR1 gene of the proband, which has co-segregated with the disease phenotype in the family. The results of minigene assay showed abnormal splicing of exon 5. The variant was not detected in the fetal amniotic fluid. Fetal growth and development were normal one year after the birth.
CONCLUSION
The c.1129-1G>C variant of the TBR1 probably underlay the disease in of the pedigree. Timely prenatal genetic diagnosis and consultation can help to stop the transmission of the pathogenic variant.
