Introduction Trauma is one of the leading causes of mortality, morbidity and disability worldwide. In developing countries, the magnitude of the problem has been increasing consuming more and more of the meager health resources of these nations. Moreover, trauma mostly affects people in their productive years of life, hence the high economic and social burden to society. The causes of trauma are various and their relative incidence varies in different populations. Immediate death (50%) • Occur in the first few minutes after the accident • Are due to extensive and lethal injuries to the brain, heart & major blood vessels 2. Early deaths (30%) • Occur in the first few hours • Are due to the collections and bleedings in the chest and abdomen, extensive fractures and increased intracranial pressure • Early resuscitation, diagnosis and appropriate management can prevent these deaths. Types of Trauma: Trauma can be classified according to the: I- Cause: Homicidal injuries Road traffic accident and falls Industrial accidents, burn, etc. I- The primary survey and resuscitation This part of management comprises a quick evaluation of the patient to detect immediately life threatening situations and institution of measures to correct them. In a trauma victim, it may be compromised by the back fallen tongue, broken tooth, vomitus, blood etc. If the air way is compromised, use suctioning, jaw trust, positioning, oropharyngeal tube or endotracheal tube to open it, taking care of the cervical spine. It may be compromised by pneumothorax, hemothorax or multiple rib fractures causing flail chest. Look for external hemorrhage and arrest it by pressure, bandaging or tourniquet if the other methods fail. Tachycardia, hypotension, pallor may mean bleeding into the body cavities or from an obvious external wound. E- Expose (undress) the patient fully for examination not to miss serious injuries. It includes the following aspects: A- Take History: The informant may be the injured patient, relatives, police or ambulance personnel. The history should include: • Time of injury, • Mechanism of injury, • Amount of bleeding, • Loss of consciousness, • Any intervention performed or drugs given should be asked for. C- Make necessary investigations such as hematocrite, cross-match, urinalysis, X-ray, ultrasound, etc. However, never send a patient with unstable vital signs for investigation or referral before resuscitation. These include poor condition and design of roads, traffic mix (sharing of road by vehicles of different speeds and pedestrians), poor condition of the vehicles and poor traffic rule enforcement. The incidence of this serious problem can be reduced by improving the public awareness and the quality of training given to the drivers and strict enforcement of traffic rules. Moreover, improving the design and quality of the roads and regular checkup of vehicle fitness would help alleviate the problem. In many developing countries like Ethiopia, the magnitude of the problem is big due to high distribution of firearms among civilians who have little or no knowledge on safe handling and usage. It is made worse by the presence of large number of land mines, which are remnants of repeated wars and conflicts in these poor nations. Generally, missile injuries may be caused by bullets from pistols, rifles, machine guns or fragments from exploded grenades and mines. The degree of injury sustained depends on the amount of energy transferred from the missile to the patient as formulated below. The extensive tissue injury with the high degree of contamination creates a perfect medium for life threatening infection to occur. Missile injuries are classified into: I- Low- velocity missile injuries • Comprise missiles fired from hand guns (<400m/s) • Injury is limited to the path of the bullet. All patients with missile injuries should receive broad spectrum antibiotics and tetanus prophylaxis. It is mostly seen in developing countries where there is overcrowding, poor housing designs and wide spread usage of open fire for cooking. Types of burns, according to the mechanism, include: • Flame burn • Scalding • Chemical burn • Electrical burn, etc. The severity of a burn injury is a function of the burn depth (degree) and the extent or percentage of the body surface that is burned. Determining the percentage of burn surface is important to calculate the amount of fluid requirement while determination of burn depth is important for burn wound management. Classification of Burn according to depth (degree) 1- First degree burn: It involves the epidermis only and manifests with erythema. The extent or percentage of burn is determined by the “rule of nine” in which the body surface is divided into eleven parts each constituting 9% of the total (fig.

Hormones produced by the anterior pituitary (in response to releasing hormones) enter a secondary capillary plexus buy cheap flagyl 500mg on-line, and from there drain into the circulation order 500mg flagyl fast delivery. The hypothalamus produces separate hormones that stimulate or inhibit hormone production in the anterior pituitary. Growth Hormone The endocrine system regulates the growth of the human body, protein synthesis, and cellular replication. Its primary function is anabolic; it promotes protein synthesis and tissue building through direct and indirect mechanisms (Figure 17. As a result, many tissues switch from glucose to fatty acids as their main energy source, which means that less glucose is taken up from the bloodstream. Follicle-Stimulating Hormone and Luteinizing Hormone The endocrine glands secrete a variety of hormones that control the development and regulation of the reproductive system (these glands include the anterior pituitary, the adrenal cortex, and the gonads—the testes in males and the ovaries in females). Much of the development of the reproductive system occurs during puberty and is marked by the development of sex-specific characteristics in both male and female adolescents. Throughout life, gonadotropins regulate reproductive function and, in the case of women, the onset and cessation of reproductive capacity. During pregnancy, it contributes to development of the mammary glands, and after birth, it stimulates the mammary glands to produce breast milk. However, the effects of prolactin depend heavily upon the permissive effects of estrogens, progesterone, and other hormones. Nevertheless, this hormone is capable of darkening of the skin by inducing melanin production in the skin’s melanocytes. Each of the thyroid lobes are embedded with parathyroid glands, primarily on their posterior surfaces. Surrounded by a wall of epithelial follicle cells, the colloid is the center of thyroid hormone production, and that production is dependent on the hormones’ essential and unique component: iodine. The following steps outline the hormones’ assembly: This OpenStax book is available for free at http://cnx. As a result, the concentration of iodide ions “trapped” in the follicular cells is many times higher than the concentration in the bloodstream. The oxidation of two iodide ions (2 I ) results in iodine (I ), which passes2 through the follicle cell membrane into the colloid. In the colloid, peroxidase enzymes link the iodine to the tyrosine amino acids in thyroglobulin to produce two intermediaries: a tyrosine attached to one iodine and a tyrosine attached to two iodines. When one of each of these intermediaries is linked by covalent bonds, the resulting compound is triiodothyronine (T ), a thyroid hormone with3 three iodines. Much more commonly, two copies of the second intermediary bond, forming tetraiodothyronine, also known as thyroxine (T ), a thyroid hormone with four iodines. There, lysosomal enzymes break apart the thyroglobulin colloid, releasing free T and T , which diffuse3 4 across the follicle cell membrane and enter the bloodstream. When blood levels of T and T begin to decline, bound T and3 4 3 T are released from these plasma proteins and readily cross the membrane of target cells. Functions of Thyroid Hormones The thyroid hormones, T3 and T , are often referred to as metabolic hormones because their levels influence the body’s4 basal metabolic rate, the amount of energy used by the body at rest. Adequate levels of thyroid hormones are also required for protein synthesis and for fetal and childhood tissue development and growth. They are especially critical for normal development of the nervous system both in utero and in early childhood, and they continue to support neurological function in adults. As noted earlier, these thyroid hormones have a complex interrelationship with reproductive hormones, and deficiencies can influence libido, fertility, and other aspects of reproductive function. Finally, thyroid hormones increase the body’s sensitivity to catecholamines (epinephrine and norepinephrine) from the adrenal medulla by upregulation of receptors in the blood vessels. When levels of T3 and T4 hormones are excessive, this effect accelerates the heart rate, strengthens the heartbeat, and increases blood pressure. Because thyroid hormones regulate metabolism, heat production, protein synthesis, and many other body functions, thyroid disorders can have severe and widespread consequences. But for much of the world’s population,3 4 foods do not provide adequate levels of this mineral, because the amount varies according to the level in the soil in which the food was grown, as well as the irrigation and fertilizers used. Marine fish and shrimp tend to have high levels because they concentrate iodine from seawater, but many people in landlocked regions lack access to seafood. Fortification of salt with iodine began in the United States in 1924, and international efforts to iodize salt in the world’s poorest nations continue today. Dietary iodine deficiency can result in the impaired ability to synthesize T3 and T , leading to a variety of severe4 disorders. As a result of this hyperstimulation, thyroglobulin accumulates in the thyroid gland follicles, increasing their deposits of colloid. The accumulation of colloid increases the overall size of the thyroid gland, a condition called a goiter (Figure 17.
