This paper describes a simple method of classification and evaluation of the functional results of replanted and revascularized parts in the hand. The results are presented in graphic form and have been analyzed to correlate various factors: injured part, cause, and zone (level) of injury. The type of injury, ischemic time and age have been studied in more detail to determine their influence of the final functional result. The series contains 187 amputated and devascularized parts of the hand in 119 patients who have undergone surgery at the Prince of Wales Hospital from 1984 through 1988. The length of cold or warm ischemic times, up to 16 hours in this series, while not affecting survival of the amputated part, does adversely affect the functional result. The survival rate of replanted parts in children was significantly less favorable than in adults, but the functional results were uniformly superior.

Background: Boxing is a sport well-known for the risk of injury. However, the epidemiology of boxing-associated fractures has not been well studied. This study aims to report the characteristics of boxing fractures that lead to presentation to the emergency room and evaluate the demographics and practices of the patients to prevent these injuries.

Background: Vaginal delivery in twins is feasible but challenging. Successful vaginal delivery of a non-vertex second twin depends on knowledge of specific obstetrical maneuvers. Skill acquisition at the patient's bedside is difficult, making simulation training an integral part of obstetrics and gynecology residency programs.

Selectively stopping individual parts of planned or ongoing movements is an everyday motor skill. For example, while walking in public you may stop yourself from waving at a stranger who you mistook for a friend while continuing to walk. Despite its ubiquity, our ability to selectively stop actions is limited.

Sign language is a form of non-verbal communication used by people with hearing disability. This form of communication relies on the use of signs, gestures, facial expressions, and more. Considering that in Colombia, the population with hearing impairments is around half a million, a database of dynamic, alphanumeric signs and commonly used words was created to establish a basic conversation.
