With a significant proportion of the worlds population remaining barefoot, minor skin trauma is a frequent cause of local infection. The rising incidence of diabetes means that this is now a potent cause of major infections. Even with relatively minor bacterial infec tions, lymphatic spread is not uncommon. Local investigation with wound swabs, culture of discharged material and skin scrap ings or nail clippings can be helpful in identi fyingtheorganism. Bloodinvestigationssuch as full blood count, blood sugar and blood cultures can be helpful in determining the exact diagnosis and monitoring the benefit of treatment. Treatment Treatment the basic principles of management involve rest, elevation of foot, antibiotics and where necessary, surgical debridement. Trimming the nail too 67 Section 2 Surgical Infection and Burn excessive amounts of keratin and other debris around the nail plates. Pathogenesis and Pathology the presence of poor vascularity (ischemia) and neuropathy are the two major predispos ing factors for the development of diabetic foot infections. The growth factors are released by ischemic tissues and cause endothelial cells to proliferate. The nail appears to be digging under the skin producing an inflamed tender lesion. The corner of the nail on the affected side cannot be seen as it is buried in the surround ing soft tissue. Peripheral neuropathies this clearly predisposes the patients to unrec ognized injury, which potentiates the risk of bacterial invasion and infection. The end result is decreased plantar sensation, intrinsic muscle atrophy, and lack of autonomic,glandular and vasomotor responses. Intrinsic muscle atrophy produces tendon imbalances that expose the metatarsal heads to excessive trauma. There is a progression from this superficial form of infection through deep infection and abscess formation to osteomyelitis. If this situation is not brought under rapid control the foot will become gangrenous. Diabetic foot Diabetes Treatment In the initial stages the condition can be con trolled by footwear that does not press on the affected toe. During routine trimming the nail is cut straight and no attempt should be made to clip the corners. Unfortunately this treatment is not effec tive in many cases and surgical intervention becomes necessary once an ingrowing toe nail has been infected a few times to prevent recurrence. Deeper infection may involve soft tissue only or can involve bones (osteitis or osteomyelitis).

Cell bodies of first-order afferent neurons of the facial nerve are located in the geniculate ganglion; those of the glossopharyngeal nerve lie in its superior and petrosal ganglia; and those of the vagal nerve are located in the jugular ganglion (somatic) and the ganglion nodosum (visceral) treatment cervical cancer order persantine on line. Second-Order Neurons As afferent fibers enter the spinal cord treatment hypercalcemia buy persantine 25mg, they segregate according to size symptoms kidney disease buy persantine cheap, with large, myelinated fibers becoming medial, and small, unmyelinated fibers becoming lateral. In many instances they communicate with second-order neurons through interneurons. The first six laminae, which make up the dorsal horn, receive all afferent neural activity and represent the principal site of modulation of pain by ascending and descending neural pathways. Nociceptive-specific neurons are arranged somatotopically in lamina I and have discrete, somatic receptive fields; they are normally silent and respond only to high-threshold noxious stimulation, poorly encoding stimulus intensity. In contrast, nociceptive A fibers synapse mainly in laminae I and V, and, to a lesser degree, in lamina X. Lamina I responds primarily to noxious (nociceptive) stimuli from cutaneous and deep somatic tissues. It is also of special interest because it is believed to be a major site of action for opioids. Visceral afferents terminate primarily in lamina V, and, to a lesser extent, in lamina I. These two laminae represent points of central convergence between somatic and visceral inputs. Lamina V responds to both noxious and nonnoxious sensory input and receives both visceral and somatic pain afferents. Compared with somatic fibers, visceral nociceptive fibers are fewer in number, more widely distributed, proportionately activate a larger number of spinal neurons, and are not organized somatotopically. The Spinothalamic Tract the axons of most second-order neurons cross the midline close to their dermatomal level of origin (at the anterior commissure) to the contralateral side of the spinal cord before they form the spinothalamic tract and send their fibers to the thalamus, the reticular formation, the nucleus raphe magnus, and the periaqueductal gray. The lateral spinothalamic (neospinothalamic) tract projects mainly to the ventral posterolateral nucleus of the thalamus and carries discriminative aspects of pain, such as location, intensity, and duration. The medial spinothalamic (paleospinothalamic) tract projects to the medial thalamus and is responsible for mediating the autonomic and unpleasant emotional perceptions of pain. Lastly, some fibers in the dorsal columns (which mainly carry light touch and proprioception) are responsive to pain; they ascend medially and ipsilaterally. Note the spatial distribution of fibers from different spinal levels: cervical (C), thoracic (T), lumbar (L), and sacral (S). Integration with the Sympathetic and Motor Systems Somatic and visceral afferents are fully integrated with the skeletal motor and sympathetic systems in the spinal cord, brainstem, and higher centers. Afferent dorsal horn neurons synapse both directly and indirectly with anterior horn motor neurons. These synapses are responsible for the reflex muscle activity-whether normal or abnormal-that is associated with pain. In a similar fashion, synapses between afferent nociceptive neurons and sympathetic neurons in the intermediolateral column result in reflex sympathetically mediated vasoconstriction, smooth muscle spasm, and the release of catecholamines, both locally and from the adrenal medulla. Although most neurons from the lateral thalamic nuclei project to the primary somatosensory cortex, neurons from the intralaminar and medial nuclei project to the anterior cingulate gyrus and are likely involved in mediating the suffering and emotional components of pain. Collateral fibers also project to the reticular activating system and the hypothalamus; these are likely responsible for the arousal response to pain. Alternate Pain Pathways As with epicritic sensation, pain fibers ascend diffusely, ipsilaterally, and contralaterally; some patients continue to perceive pain following ablation of the contralateral spinothalamic tract, and therefore other ascending pain pathways are also important.

Their direct effects include promotion of protein synthesis in the liver and muscle and lipolysis of fat stores. Local Effects: Their actions help to contain tissue damage by contributing to the inflammatory reaction through vasodilatation and increased permeability of vessels, migration of neutrophils and monocytes to the wounds, activation of the coagulation and complement cascades and proliferation of endothelial cells and fibroblasts.

They are released by thrombin, catrequired for acute phase protein synthesis to echolamines, hypoxia and endotoxins. This shunting represents a reprioritization ability of endothelial cells to albumin. The anabolic phase is characterized by increased metabolism, hyperglycemia, lipolysis, negative nitrogen balance, increased heat production and oxygen consumption. The increase in metabolic rate ranges from about 10 percent in elective surgical operations to 50 percent in multiple trauma and 200 percent in major burns. The anabolic phase, on the other hand is characterized by protein and fat synthesis and associated with weight gain. Resting energy expenditure is increased after tissue injury, the degree of increase being proportional to the magnitude of trauma. The muscle and liver glycogen, however, cannot continue to supply glucose all the time, as its total store would be exhausted in a day or two. Protein can also be used as an energy source but it cannot be mobilized beyond a certain level. It is important to spare proteins since their excessive breakdown would lead to muscle wasting, ineffective coughing, impaired wound healing and a diminished synthesis of enzymes. Therefore, the calorie distribution of protein to the fuel mixture of the injured is small and the main energy requirement is met from fat. Physiological Basis of Surger y carbohydrate Metabolism After Injury of triglycerides to fatty acids and glycerol. Fatty acids are burnt in the liver Hyperglycemia occurs immediately after injury to supply energy for gluconeogenesis and because glucose is mobilized from stored gly- in the periphery to supply energy directly.
