Foreign body aspiration x-ray findings that can be seen with foreign body aspiration include obstructive emphysema, atelectasis, and consolidation. While, x-ray can be used to visualize the location and identity of a foreign body, rigid bronchoscopy under general anesthesia is the gold-standard for diagnosis since the foreign body can be visualized and removed with this intervention. Rigid bronchoscopy is indicated when two of the three following criteria are met: report of foreign body aspiration by the patient or a witness, abnormal lung exam findings, or abnormal chest x-ray findings. Treatment of foreign body aspiration is determined by the severity of obstruction of the
Cold and heat adaptations in humans observed in Eskimo, who have shorter limbs than other people and are laterally built. Origins of heat and cold adaptations can be explained by climatic adaptation. This can be traced back to the body’s responses to differing environments immediately after leaving Africa, such as extreme cold, humid heat, desert conditions, and high altitudes. Ambient air temperature affects how much energy investment the human body must make. The temperature that requires the least amount of energy investment is 21 °C (69.8 °F). The body controls its temperature through the hypothalamus. Thermoreceptors in the skin send signals to the hypothalamus, which indicate
