A novel approach has been used to identify functional interactions relevant to human disease. Using high-throughput human-yeast genetic interaction screens, a first draft of disease interactome was obtained. This was achieved by first searching for candidate human disease genes that confer toxicity in yeast, and second, identifying modulators of toxicity. This study found potentially disease-relevant interactions by analyzing the network of functional interactions and focusing on genes implicated in amyotrophic lateral sclerosis (ALS), for example. In the subsequent proof-of-concept study focused on ALS, similar functional relationships between a specific kinase and ALS-associated genes were observed in mammalian cells and zebrafish, supporting findings in human-yeast genetic interaction screens. Results of combined analyses highlighted MAP2K5 kinase as a potential therapeutic target in ALS.

Purpose: The aim of this article is to review a group of lesions associated with periodontal ligament (PDL) widening. Materials and Methods: An electronic search was performed using specialized databases such as Google Scholar, PubMed, PubMed Central, Science Direct, and Scopus to find relevant studies by using keywords such as "periodontium", "periodontal ligament", "periodontal ligament space", "widened periodontal ligament", and "periodontal ligament widening". Results: Out of nearly 200 articles, about 60 were broadly relevant to the topic. Ultimately, 47 articles closely related to the topic of interest were reviewed. When the relevant data were compiled, the following 10 entities were identified: occlusal/orthodontic trauma, periodontal disease/periodontitis, pulpo-periapical lesions, osteosarcoma, chondrosarcoma, non-Hodgkin lymphoma, progressive systemic sclerosis, radiation-induced bone defect, bisphosphonate-related osteonecrosis, and osteomyelitis. Conclusion: Although PDL widening may be encountered by many dentists during their routine daily procedures, the clinician should consider some serious related conditions as well.

Purpose: The purpose of this study was to evaluate the correlation between the clinical symptoms of temporomandibular disorder and findings in the magnetic resonance imaging (MRI). Materials and Methods: Clinical data and MRI images were collected from a total of 240 German patients. Clinical symptoms were briefed as joint clicking, crepitus and pain. MRI findings were further defined according to the condyle position, condyle degeneration, disc positon, disc degeneration and the presence of osteophyte/sclerosis/synovitis. Hypermobility was separately recorded. Correlation analysis between parameters was performed. Result: Joint clicking had a positive correlation with unilateral disc degeneration, osteophyte, sclerosis and synovitis. Crepitus had a significant correlation with bilateral osteophyte. Pain was not correlated with any MRI findings except hypermobility. Conclusion: Selective correlations between the MRI findings and clinical symptoms were elucidated. The results of this study imply that condyle-disc deformities could be advanced without pain, and that joint clicking and crepitus could be clinical symptoms of condyle-disc degeneration.

A 77-year-old male with amyotrophic lateral sclerosis had a hypoxic event. After resuscitation, generalized myoclonus appeared and resolved after two days. Five days after the hypoxic event, myoclonic seizures re-emerged right after performing a somatosensory evoked potential and persisted for ten days. Electroencephalogram revealed frequent bi-hemispheric synchronous spike and waves in the central areas. We suggest that somatosensory evoked potential testing may trigger myoclonic status epilepticus. Underlying cortical degeneration associated with amyotrophic lateral sclerosis could attribute to this phenomenon.

We report a case of fluoroscopy-guided intraarticular steroid injection for sternoclavicular joint (SCJ) arthritis caused by limited cutaneous systemic sclerosis (SSc). A 50-year-old woman diagnosed with limited cutaneous SSc presented with swelling and pain in the right SCJ. MRI revealed signs of inflammation consistent with right-sided sternoclavicular joint arthritis. After the failure of oral medications, we performed fluoroscopy-guided injection in this region. She reported complete resolution of her symptoms at 4 and 12-week follow-ups. This outcome suggests that a fluoroscopy-guided SCJ injection might be a safe and successful treatment option for sternoclavicular joint arthritis.

목적 : 대표적인 motor neuron disease(MND)이면서 가장 치명적인 신경퇴행성 질환인 ALS의 발생 양상과 한방치료효과에 대하여 연구하였다. 방법: 상지대학교 부속 한방병원에 래원한 ALS 환자들의 성별, 연령, 발병일, 발병양상, 래원 당시의 병태양상 등을 분석하였고, 이 중 3개월 이상 입원치료를 통하여 치료과정 평가가 가능하였던 18명의 환자들의 치료 전과 치료 후의 변화양상을 평가하였다. 결과 : 외국의 보고에 비하여 여성 환자가 많았고 발병 연령도 유의하게 낮았으며 상지에서 최초의 증상이 발현되는 비율이 상대적으로 높았다. Bulbar From의 비율도 높았고, 대부분의 환자가 여성인 것도 특이하였다. 환자들이 생각하는 질병의 발생원인 중 약 80%가 stress나 정신적 충격 등을 지적하여 정신적 불안상태가 유관함을 추정할 수 있었다. 한방치료가 ALS를 호전시키지는 못하였으나 진행을 억제하였고, 국소적인 주소증을 완화시키며 심리적 안정 상태를 유지하는데 도움이 된다고 평가되었다.

Flail arm syndrome (FAS), known as one of the atypical amyotrophic lateral sclerosis (ALS) variants, has a similar clinical course and pathologic findings as ALS. Therefore it is difficult to differentiate between ALS and FAS at a glance. There are few reports involving individual analysis of FAS patients to date. The findings of polysomnography (PSG) in patient with FAS are not well known. We report a male FAS patient with review of literatures and several issues related to the diagnostic process.

Neurodegenerative diseases such as Parkinson's disease and amyotrophic lateral sclerosis may induce impairment of speech motor system. This review discusses the characteristics of dysarthria and symptom management for these conditions. Given the progressive nature of the neurodegenerative diseases, speech-language pathologists must be aware of appropriate augmentative and alternative communication equipment at the early stage of the disease course. Patients with neurodegenerative diseases can maintain functional communication with augmentative and alternative communication supports.

Significant research efforts are ongoing to elucidate the complex molecular mechanisms underlying amyotrophic lateral sclerosis (ALS), which may in turn pinpoint potential therapeutic targets for treatment. The ALS research field has evolved with recent discoveries of numerous genetic mutations in ALS patients, many of which are in genes encoding RNA binding proteins (RBPs), including TDP-43, FUS, ATXN2, TAF15, EWSR1, hnRNPA1, hnRNPA2/B1, MATR3 and TIA1. Accumulating evidence from studies on these ALS-linked RBPs suggests that dysregulation of RNA metabolism, cytoplasmic mislocalization of RBPs, dysfunction in stress granule dynamics of RBPs and increased propensity of mutant RBPs to aggregate may lead to ALS pathogenesis. Here, we review current knowledge of the biological function of these RBPs and the contributions of ALS-linked mutations to disease pathogenesis.
