Modern tissue engineering has made substantial advancements that have revolutionized plastic surgery. Acellular dermal matrix (ADM) is an example that has gained considerable attention recently. ADM can be made from humans, bovines, or porcine tissues. ADM acts as a scaffold that incorporates into the recipient tissue. It is gradually infiltrated by fibroblasts and vascularized. Fortunately, many techniques have been used to remove cellular and antigenic components from ADM to minimize immune system rejection. ADM is made of collagen, fibronectin, elastin, laminin, glycosaminoglycans, and hyaluronic acid. It is used in critical wounds (e.g., diabetic wounds) to protect soft tissue and accelerate wound healing. It is also used in implant-based breast reconstruction surgery to improve aesthetic outcomes and reduce capsule contracture risk. ADM has also gained attention in abdominal and chest wall defects. Some studies have shown that ADM is associated with less erosion and infection in abdominal hernias than synthetic meshes. However, its higher cost prevents it from being commonly used in hernia repair. Also, using ADM in tendon repair (e.g., Achilles tendon) has been associated with increased stability and reduced rejection rate. Despite its advantages, ADM might result in complications such as hematoma, seroma, necrosis, and infection. Moreover, ADM is expensive, making it an unsuitable option for many patients. Finally, the literature on ADM is insufficient, and more research on the results of ADM usage in surgeries is needed. This article aims to review the literature regarding the application, Benefits, and costs of ADM in reconstructive surgery.

Osmotic demyelination syndrome (ODS) happens in osmotic stress. Thiamine deficiency causes Wernicke-Korsakoff syndrome (WKS). A 39-year-old woman with anorexia nervosa presented with impaired consciousness. Sodium was 179, MRI showed signs of ODS and WKS. Hypernatremia is argued as a rare ODS cause. In malnutrition, WKS might overlap with ODS.

The effects of a sufficient amounts of vitamins and nutrients on the proper function of the nervous system have always been regarded by scientists. In recent years, there are many studies have been done on controling or improving the symptoms of neurological and behavioral disorders which is created by changes in the level of vitamins and other nutrition, such as omega-3 and iron supplements. Autism spectrum disorder (ASD) is a neurodevelopmental disorder that causes disruption individual communication, especially in social interactions. Its symptoms include anxiety, violence, depression, self-injury, trouble with social contact and pervasive, stereotyped, and repetitive behavior. ASD is most noticeable in early childhood. Attention Deficit Hyperactivity Disorder (ADHD) is a lasting pattern of inattention with or without hyperactivity that makes functional disrupt in daily life. ADHD symptoms included; impulsivity, hyperactivity, inattention, restlessness, talkativeness, excessive fidgeting in situations as sitting, meetings, lectures, or at the movies, boredom, inability to make decisions, and procrastination. The exact etiology of ADHD has not yet been found, but several observations have been assumed the reduced function of the brain lead to deficits in motor planning and cognitive processing. It has been shown that Pro-inflammatory cytokines and oxidative stress biomarkers could be increased in both ASD and ADHD. Several studies have been done to illustrate if vitamins and other dietary supplements are effective in treatment and prevention of ASD and ADHD. In this review, we aim to evaluate the effects of vitamins and other dietary supplements (e.g., melatonin, zinc supplements, magnesium supplements) on ASD and ADHD.
