Clinical management of constipation has evolved from the prescription of dietary supplements, to potent stimulant laxatives, to corrective surgeries for organic blockage. Yet constipation does not respond to a one-size-fits-all treatment. In recent decades, the Bristol Stool Form Scale and Rome III diagnostic criteria have allowed for algorithmic diagnosis, yet these criteria could benefit from further extension and meaningful discussion. This review incorporates pertinent clinical updates and uses the anatomy and physiology of constipation as helpful signposts for the practicing clinician.
The creases of the palm have been of interest for clinicians, anthropologists, and palmists for hundreds of years, but the variations in them have only been studied during the past 50 years. The simian crease, aptly named for its resemblance to the palmar creases of nonhuman simian primates, has received recognition clinically and anthropologically owing to its abnormal appearance and confounding cytogenetic etiology. Given the rarity of these palmar creases but also their usefulness in diagnosing congenital disorders, discussion of cases of those disorders could provide clinicians with further helpful diagnostic knowledge. This review of the literature focuses on the history, embryology, genetic and hereditary origins, and clinical significance of simian creases for the benefit of the diagnosing clinician.
Obesity is a worldwide issue that many global health authorities consider a growing epidemic. Having a positive correlation between increases in the industrialization of processed foods and sedentary occupations as well as a lack of access to healthcare in poorer socioeconomic areas, obesity is a multifactorial disease affecting several organ systems. The tendency for obesity to cause detrimental changes to the human body is a focal point for healthcare providers to establish more effective clinical treatment and management plans. Implementing comprehensive global educational programs to decrease the prevalence of this unforgiving disease is imperative for a healthier future. Herein, we have provided a comprehensive review of the health effects of obesity upon the human body for the interest of many practicing clinicians managing this health crisis.
The evolution and variation of human anatomy are of great interest to physicians and anatomists. Some of these variations can be categorized as vestigial, accessory or atavistic structures. Vestigial structures are rudimentary structures normally seen in human anatomy that correspond to fully elaborated structures in mammals with more primitive phenotypes. They are present in all members of a population. Some of the more common vestigial structures in humans include the wisdom teeth, the appendix and the coccyx.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
