Stress Fracture in Non-Athletes: A Systematic Review

The present study seeks to discuss the incidence of a stress fracture in not athletes. This type of pathology occurs as a result of a repetitive number of movements in a given region, fatigue and muscle imbalance are the main responsible for these fractures, which mainly affect runners and military, groups that are more susceptible to a large amount of impact In practice, and has been increasing in non-athletes. To do so, it reviews the literature based on the first descriptions of the stress fracture, the causes of this type of occurrence, the results on the patient's body, and the modes of treatment and recovery. The objective of this study is to review the literature currently available to aggregate the most relevant information regarding this pathology

Photoprotection and Vitamin D: A Concise Systematic Review

One of the main factors for the increase in the incidence of skin cancer in Brazil today is exposure to solar radiation. The main means of prevention is through photoprotection, together with factors such as solar incidence in the region, the habits of the population, and the skin phototype. The relationship between photoprotection and vitamin D is fundamental for patient orientation since photoprotection is a practice widely used today for all people, both those who have already suffered some type of skin cancer and others who are at greater risk or not. to develop it. On the other hand, some studies suggest that the photoprotection of the skin would jeopardize the development of Vitamin D, which may cause its deficiency, and may subject patients to future changes in bone mineralization, increasing the risk of bone deformities and fractures since the vitamin D is essential for bone tissue and its production is stimulated by skin exposure to ultraviolet B radiation (UVB), with natural sources limited through the diet. The discussion about the relationship between photoprotection and vitamin D is essential to establish the right conditions for each patient

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
