Horizontal gaze palsy with progressive scoliosis (HGPPS) is a rare, autosomal recessive inherited disorder caused by mutations in ROBO3 gene. The clinical features of HGPPS include horizontal gaze palsy, progressive scoliosis, other oculomotor abnormalities such as strabismus and nystagmus. Whole-exome sequencing (WES) is used to diagnose rare Mendelian disorders, when routine standard tests have failed to make a formal pathological diagnosis.

Background: Port-wine stain (PWS) is a congenital capillary malformation associated with negative effects on the quality of life and psychological health of the patients. Pulsed dye laser (PDL) is the current treatment of choice for PWS; however, there is little information on the factors determining the treatment price of PWS. We aim to explore the factors determining the treatment price of PWS.

While bacteria can be beneficial to our health, their deadly pathogenic potential has been an ever-present concern exacerbated by the emergence of drug-resistant strains. As such, there is a pressing urgency for an enhanced understanding of their gene function and regulation, which could mediate the development of novel antimicrobials. Transcriptomic analyses have been established as insightful and indispensable to the functional characterization of genes and identification of new biological pathways, but in the context of bacterial studies, they remain limited to species-specific datasets.

Introduction: Asian patients often seek to address lower facial aging through clinical interventions that increase anterior projection and jawline contouring. The Definisse™ (also known as Happy Lift™) thread lift treatment uses barbed absorbable threads to suspend tissues and induce biostimulation. We evaluated the efficacy and safety of absorbable barbed threads for lower facial reshaping in Thai patients.

Introduction: Port-wine stain (PWS) is a congenital malformation that does not resolve spontaneously and can cause a physiological or psychological burden to the patients. At present, most of the studies done on PWS are focused on the treatment rather than the quality of life and psychological effects of the disease.

Material And Methods: A comprehensive literature search was done in MEDLINE using PubMed database, Embase, and Cochrane.

Background: Port-wine stain (PWS) is a congenital malformation that does not resolve spontaneously and can lead to social and self-stigma. However, little is known about how PWS affects the patients' quality of life (QoL) and psychosocial well-being. In this article, we examine the existing empirical evidence on self-stigma caused by PWS.

Vaginal laxity, a common cause of decreased sexual sensation, is a common problem affecting the quality of life of women worldwide. Recently, lasers and energy-based devices (EBDs) have been applied in the treatment of this condition. The aim of this study was to compare the efficacy and safety of Er:YAG laser and placebo in treating decreased sexual sensation in Asians.

Topical corticosteroid delivery following fractional laser treatment is an effective means of treating hypertrophic scars. However, the relative efficacy of adjuvant corticosteroid treatment vs fractional laser mono-therapy alone is unclear. The aim of this study was to compare the efficacy and safety of fractional laser-assisted topical corticosteroid delivery with fractional laser monotherapy in the treatment of hyper-trophic scars.

Introduction: Port-wine stain (PWS) is a progressive capillary malformation that does not resolve spontaneously without treatment. Pulsed dye laser (PDL) is currently the gold standard treatment for PWS, although it is difficult to attain complete clearance and recurrences are common. This study determined the cost-effectiveness of PDL treatment among Thai patients with facial PWS.

The fungi kingdom is composed of eukaryotic heterotrophs, which are responsible for balancing the ecosystem and play a major role as decomposers. They also produce a vast diversity of secondary metabolites, which have antibiotic or pharmacological properties. However, our lack of knowledge of gene function in fungi precludes us from tailoring them to our needs and tapping into their metabolic diversity.

TAR DNA-binding protein 43 (TDP-43) has been identified as the major constituent of the proteinaceous inclusions that are characteristic of most forms of amyotrophic lateral sclerosis (ALS) and ubiquitin positive frontotemporal lobar degeneration (FTLD). Wild type TDP-43 inclusions are a pathological hallmark of >95% of patients with sporadic ALS and of the majority of familial ALS cases, and they are also found in a significant proportion of FTLD cases. ALS is the most common form of motor neuron disease, characterized by progressive weakness and muscular wasting, and typically leads to death within a few years of diagnosis.
