As Malaysia races towards a developed nation status, children are increasingly being ferried daily in vehicles almost exclusively as the majority of the population are able to afford private transportations. This paper reviews the current safety concerns for children whilst going in vehicles on Malaysian roads and the steps undertaken to address the need to enhance children’s safety whilst going in these vehicles and suggest possible remedial action to counter the possible lack of awareness for children’s safety whilst in these vehicles. This paper focuses on children on motorcycles and private vehicles (cars, vans and multi-purpose vehicle (MPV)) and excludes other form of transport (buses, lorries) as this paper tries to put forth measures that can be undertaken by the children’s parents and guardian to better enhance the safety of their children. A search was undertaken of all the major database of articles. Articles related to children’s safety systems, children related injuries, children related accident data, available laws and legislation were reviewed to present the need for greater awareness of children’s safety while going in vehicles in Malaysia. There are currently already safety legislations, measures, steps and equipments in place in ensuring the safety of children whilst going in vehicles on Malaysian roads. However, enforcement of laws in developing countries are not easy and we have to start at the root of the problem which is the parents and adults who ferry these children in vehicles. There is a pressing need to educate parents and adults alike on the urgent undertaking of child safety whilst in vehicles. Engineering countermeasures and intervention are probably needed to protect these vulnerable users. For vehicles, a device capable of providing some sort of protection to the child whilst riding pillion should be designed and developed. A legislation mandating the use of child seats whilst ensuring the child seats are affordable to the masses.

Myasthenia gravis (MG) is a disease of neuromuscular junction and mainly autoimmune in aetiology.
The state of thymus is a critical determinant for the prognosis. In this retrospective review study, we
aimed at clarifying the relationship between the mode of clinical presentation of MG and the radiopathological classification of the thymus. We identified patients with MG from the database of our
medical center from 1988 – 2017. The patients were classified into two groups according to their
clinical presentation: those with a typical presentation with diurnal variation, and those with an atypical
presentation of persistent weakness or respiratory failure from the beginning. The underlying thymic
state was categorized into six groups: normal, abnormal by imaging (if no operation was performed),
hyperplasia, benign thymoma, cortical type thymoma, and malignant thymoma. In total, 227 patients
(133 females and 94 males) were included in the analysis, of whom 68% were classified into the
typical presentation group. The atypical presentation correlated significantly with thymic categories
(p = 0.014) and sex (p = 0.026) but not age at onset (p = 0.232). The atypical presentation was more
common in the male patients and in those with thymic carcinoma.

Muscularis propria of the esophagus is organized into circular and longitudinal muscle layers. Goal of this review is to summarize the role of longitudinal muscle in physiology and pathophysiology of esophageal sensory and motor function. Simultaneous manometry and ultrasound imaging that measure circular and longitudinal muscle contraction respectively reveal that during peristalsis 2 layers of the esophagus contract in perfect synchrony. On the other hand, during transient relaxation of the lower esophageal sphincter (LES), longitudinal muscle contracts independently of circular muscle. Recent studies provide novel insights, i.e., longitudinal muscle contraction of the esophagus induces LES relaxation and possibly descending relaxation of the esophagus. In achalasia esophagus and other motility disorders there is discoordination between the 2 muscle layers. Longitudinal muscle contraction patterns are different in the recently described three types of achalasia identified by high-resolution manometry. Robust contraction of the longitudinal muscle in type II achalasia causes pan-esophageal pressurization and is the mechanism of whatever little esophageal emptying that take place in the absence of peristalsis and impaired LES relaxation. It may be that preserved longitudinal muscle contraction is also the reason for superior outcome to medical/surgical therapy in type II achalasia esophagus. Prolonged contractions of longitudinal muscles of the esophagus is a possible mechanism of heartburn and "angina like" pain seen in esophageal motility disorders and possibly achalasia esophagus. Novel techniques to record longitudinal muscle contraction are on the horizon. Neuro-pharmacologic control of circular and longitudinal muscles is different, which provides an important opportunity for the development of novel pharmacological therapies to treat sensory and motor disorders of the esophagus.

OBJECTIVES: This study investigated the prevalence of reading and mathematical learning disabilities of students at primary schools in Jeju Island, South Korea. We examined major causes of learning disabilities including reading disorder, mathematical disorder, attention deficit, and other causes including socioemotional factors. METHODS: We conducted screening processes to 659 participants (340 male, 51%) in 4 elementary schools in Jeju Island. To identify the causes of learning problems, 84 children were administered tests such as the Korean-Wechsler Intelligence Scale for Children-fourth edition, the Comprehensive Learning Test-Reading/Math, and the Comprehensive Attention Test. RESULTS: This study found that 13% of elementary school students in the Jeju region had learning disabilities. Among learning disabilities, specific reading and mathematical disorders accounted for 9% of study subjects. In addition, 2% of participants had intellectual impairment and 1% had other causes such as socioemotional factors. 65% of children with learning disabilities and 74% of children with reading or mathematic disorders had concurrent attention deficit disorder. 68% of children with reading disorders also had comorbid mathematical disorder. CONCLUSION: The prevalence, causes, and comorbidity of reading and mathematical learning disabilities of students in Jeju Island, South Korea did not differ from those in foreign countries. Because most learning disabilities are complex, comprehensive evaluations and tailored interventions are necessary to help children with learning disabilities.

Objectives:
This study investigated the effectiveness of the intervention program for elementary school students with reading disorders.
Methods:
The intervention program focused on phonological awareness, phonics, and decoding training applied individually to 25 children with a reading disorder by the teachers in charge for four months. To measure the efficacy, this study evaluated the word reading accuracy, fluency, and the related cognitive functions, including phonemic awareness, phonics, and rapid automatized naming using the Computerized Comprehensive Learning Test-Reading before and after the program.
Results:
After the intervention, improvements were observed in the following: the reading fluency score and fluency percentile in the word attack test; reading accuracy rate, fluency score, and fluency percentile in the nonword decoding test; fluency score and fluency percentile in the rapid automatized naming tests; accuracy rate in the letter-sound matching test; accuracy rate in the nonword repetition test. On the other hand, there was no significant difference in the paragraph reading fluency test. According to the subtypes of reading disabilities, children with dyslexic or mixed types improved after the intervention.
Conclusion
Reading accuracy and fluency of school-aged children with reading disorders improved through the intervention program by the schoolteachers.

Background:
In lipopolysaccharide-induced RAW264.7 cells, Aster tartaric (AT) inhibits the nuclear factor kappa-light-chain-enhancer of activated B cells and MAPKs pathways and critical pathways of osteoclast development and bone resorption.
Objectives:
This study examined how aster saponin A2 (AS-A2) isolated from AT affects the processes and function of osteoclastogenesis induced by receptor activator of nuclear factor kappa-B ligand (RANKL) in RAW264.7 cells and bone marrow macrophages (BMMs).
Methods:
The cell viability, tartrate-resistant acid phosphatase staining, pit formation assay, polymerase chain reaction, and western blot were carried out to determine the effects of ASA2 on osteoclastogenesis.
Results:
In RAW264.7 and BMMs, AS-A2 decreased RANKL-initiated osteoclast differentiation in a concentration-dependent manner. In AS-A2-treated cells, the phosphorylation of ERK1/2, JNK, and p38 protein expression were reduced considerably compared to the control cells. In RAW264.7 cells, AS-A2 suppressed the RANKL-induced activation of osteoclast-related genes. During osteoclast differentiation, AS-A2 suppressed the transcriptional and translational expression of NFATc1 and c-Fos. AS-A2 inhibited osteoclast development, reducing the size of the bone resorption pit area.
Conclusion
AS-A2 isolated from AT appears to be a viable therapeutic therapy for osteolytic illnesses, such as osteoporosis, Paget’s disease, and osteogenesis imperfecta.

All drugs have both favorable therapeutic and untoward adverse effects. Conventional opioid analgesics possess both analgesia and adverse reactions, such as nausea, vomiting, and respiratory depression. The opioid ligand binds to µ opioid receptor and non-selectively activates two intracellular signaling pathways: the G protein pathway induce analgesia, while the β-arrestin pathway is responsible for the opioid-related adverse reactions. An ideal opioid should activate the G protein pathway while deactivating the β-arrestin pathway. Oliceridine (TRV130) has a novel characteristic mechanism on the action of the µ receptor G protein pathway selective (µ-GPS) modulation. Even though adverse reactions (ADRs) are significantly attenuated, while the analgesic effect is augmented, the some residual ADRs persist. Consequently, a G protein biased µ opioid ligand, oliceridine, improves the therapeutic index owing to increased analgesia with decreased adverse events. This review article provides a brief history, mechanism of action, pharmacokinetics, pharmacodynamics, and ADRs of oliceridine.

This practice parameter for non-pharmacological treatment for attention-deficit hyperactivity disorder(ADHD) review the domestic and international literature on the psychosocial treatment of children and adolescents with ADHD. This parameter include the parental training & education, cognitive behavior therapy(group or individual), social skill training, family therapy, play therapy(individual psychotherapy) and non-traditional therapy(art therapy, herbal therapy et al). Among them, there is some proven evidence only in parental training & education and cognitive behavior therapy. So, this parameter describes some details only in the field of parental training & education and cognitive behavior therapy. The efficacy or effectiveness, especially, cost-effectiveness of specific psychosocial treatment method for ADHD cannot be fairly assessed due to the scarcity of controlled clinical data. Based on the clinical expert consensus and limited evidence, we cautiously suggest the practice recommendations about the non-pharmacological psychosocial treatment for children and adolescents with ADHD.
