Body Piercings and Posttraumatic Stress Disorder Symptoms in Young Adults

Body piercing, which is prevalent in young adults, has been suggested to be associated with features usually related to posttraumatic stress disorder (PTSD) such as high‐risk behaviours and psychopathological symptoms and might be motivated by a wish to deal with prior traumatic experiences. However, to date, no research has investigated the relationship between this practice and PTSD symptoms. The present research aims to investigate the possible relationship between body piercing and PTSD symptoms in French‐speaking young adults. According to our results, having two or more body piercings was associated with a twofold increased risk for scoring above the cut‐off score for PTSD on the PTSD checklist. Our findings suggest that two or more body piercings might serve as an identifiable marker for PTSD symptoms and may have important implications for clinical screening.

RNA quality control and protein aggregates in amyotrophic lateral sclerosis: A review

Amyotrophic lateral sclerosis (ALS) is the most common motor neuron disease in adults. The biologic basis of ALS remains unknown. However, ALS research has taken a dramatic turn over the past 4 years. Ground breaking discoveries of mutations of genes that encode RNA processing proteins, and demonstration that abnormal aggregates of these and other proteins precede motor neuron loss in familial and sporadic ALS, have initiated a paradigm shift in understanding the pathogenic mechanisms of ALS. Curiously, some of these RNA binding proteins have prion‐like domains, with a propensity to self‐aggregation. The emerging hypothesis that a focal cascade of toxic protein aggregates, and their consequent non–cell‐autonomous spread to neighborhood groups of neurons, fits the classical temporo‐spatial progression of ALS. This article reviews the current research efforts toward understanding the role of RNA‐processing regulation and protein aggregates in ALS. Muscle Nerve 47:330‐338, 2013     

The history of parkinsonism: Descriptions in ancient Indian medical literature

The clinical syndrome of parkinsonism was identified in ancient India even before the period of Christ and was treated methodically. The earliest reference to bradykinesia dates to 600 bc . Evidences prove that as early as 300 bc , Charaka proposed a coherent picture of parkinsonism by describing tremor, rigidity, bradykinesia, and gait disturbances as its components. The scenario was further developed by Madhava, Vagbhata, and Dalhana all through history. The 15th‐century classic “Bhasava rajyam” introduced the term kampavata, which may be regarded as an ayurvedic analogue of parkinsonism. The pathogenesis of kampavata centered on the concept of imbalance in the vata factor, which controls psychomotor activities. The essential element in therapy was the administration of powdered seed of Mucuna pruriens, or atmagupta, which as per reports, contains 4%?6% of levodopa. In addition to proving the existence and identification of parkinsonism in ancient India, the study points to the significance of ancient Indian Sanskrit works in medical history. © 2013 Movement Disorder Society
