The Anatomy nerve passes below the piriform muscle (or pierces it), into the gluteal region and moves first laterally, then caudally. It continues between the greater trochanter and the ischial tuberosity through the inferior buttock, where it is embedded in fatty tissue in the subgluteal space. It is positioned on the dorsal side of the femoral bone, between the flexor muscles of the knee. The location of the division into the tibial and peroneal nerves varies, but usually occurs in the upper thigh. Fibers from the lateral and medial divisions of the sciatic nerve become the peroneal and tibial nerves. Fibers from the lateral division (peroneal nerve) are more prone to compression. The peroneal and tibial nerves include motor, sensory and autonomic fibers. The nerve provides motor innervation to the following muscles: the semiten- dinosus, the long head of the biceps femoris, the semimembranosus, part of the adductor magnus (medial trunk), the short head of the biceps femoris (lateral trunk) and all muscles innervated by the peroneal and tibial nerves (see Fig. Complete proximal transsection produces a paralysis of hamstring muscles and Symptoms all the muscles innervated by the peroneal and tibial nerves. Sensory loss occurs in all cutaneous areas supplied by both nerves, with the exception of a small medial zone that is innervated by the saphenous nerve. Many sciatic lesions are partial and tend to resemble peroneal nerve lesions, due to the increased susceptibility of the peroneal nerve fibers. Painful neuropathic syndromes can result from sciatic nerve lesions. Inspection and palpation along the sciatic nerve (the sciatic notch in the thigh). Signs Tenderness in the notch is a non-specific sign. Muscle testing should include hip muscles (gluteal), which should be spared. Complete lesions will lead to involvement of all muscles in the lower leg, as well as loss of sensation in all regions except the region supplied by the saphenous nerve. Severe trophic changes may be present in the tibial nerve distribution. Absent (or at least diminished) ankle jerk and gait difficulties will also occur.

Approximately 80% of cases of kyphosco- liosis are idiopathic generic midamor 45 mg with mastercard blood pressure yahoo answers. Idiopathic kyphoscoliosis commonly begins in late childhood or early adolescence and may progress in severity during these years of rapid skeletal growth purchase midamor 45 mg without a prescription pulse pressure of 100. Idiopathic kyphoscoliosis is not to be confused with kyphoscoliosis caused by a known underlying condition, such as osteoporosis or compression fractures in elder- ly patients. The incidence of kyphoscoliosis in females is four times higher than that in males. A 37-year-old man arrives at your emergency center by ambulance shortly after being involved in a motor vehicle accident. The emergency medical technician (EMT) reports that the patient is hemody- namically stable with minimal external blood loss and no loss of consciousness. The EMT reports that the patient appears to be in moderate to severe respiratory distress; the patient has a respiratory rate of 40 breaths/min and an O2 saturation of 78% while receiving supplemental oxygen at a rate of 3 L/min by nasal cannula. On physical examination, you note a remarkable 15 cm right anterolateral chest con- tusion. The contused segment appears to move paradoxically with respect to respiration. The patient has clear bilateral breath sounds in the upper and lower regions of both lungs. Which of the following statements regarding flail chest injury is most accurate for this patient? In young, otherwise healthy patients, a large flail chest segment is not a life-threatening injury B. The most appropriate step to take next in treatment of this patient is to provide supplemental oxygen by 100% nonrebreathing mask to attain O2 saturations greater than 90% C. The most appropriate step to take next in the treatment of this patient is to provide positive pressure ventilation D. The most appropriate step to take next in the treatment of this patient is to order and evaluate a stat portable chest x-ray to rule out a tension pneumothorax Key Concept/Objective: To understand emergent therapy of flail chest segment with respiratory failure Flail chest is an acute process that may lead to life-threatening abnormalities of gas exchange and mechanical function. This patient is in acute respiratory failure as a result of the massive chest-wall trauma and resultant flail segment. Stability of the thoracic cage is necessary for the muscles of inspiration to inflate the lung. In flail chest, a local- ly compliant portion of the chest wall moves inward as the remainder of the thoracic 24 BOARD REVIEW cage expands during inhalation; the same portion then moves outward during exhala- tion. Consequently, tidal volume is diminished because the region of lung associated with the chest wall abnormality paradoxically increases its volume during exhalation and deflates during inhalation. The result is progressive hypoxemia and hypercapnia. Multiple rib fractures, particularly when they occur in a parallel vertical orientation, can produce a flail chest. The degree of dysfunction is directly proportional to the volume of lung involved in paradoxical motion. Patient management may be complicated by other manifestations of trauma to the chest, such as splinting of ventilation because of pain, contusion of the underlying lung, or hemothorax or pneumothorax. Positive-pressure inflation of the lung or negative pressure applied to the chest wall corrects the abnor- mality until more definitive stabilization procedures can be undertaken. For this patient, the most appropriate step to take next is to provide posi- tive-pressure ventilation, preferably with endotracheal intubation. A chest x-ray is need- ed in this patient, but ventilatory resuscitation should take precedence. The fact that the patient has good bilateral breath sounds and is hemodynamically stable would make a significant tension pneumothorax unlikely. A 51-year-old man presents to your office for evaluation of a nonproductive cough and a "scratchy" throat. He has no significant medical history but does have a 50-pack-year history of cigarette smoking. He states that his cough and mild sore throat started 3 weeks ago when he developed a "head cold" and that he has had a persistently runny nose since. Because of his significant smoking history, you order a routine chest x-ray, which is interpret- ed as being normal except for an elevated right hemidiaphragm.
Because this patient is used to a sedentary lifestyle 4 BOARD REVIEW and is not strongly motivated to begin exercising midamor 45mg arteria faciei, compliance with exercise recommen- dations may be an issue safe midamor 45mg blood pressure testing. Lifestyle interventions appear to be as effective as formal exercise programs of similar intensity in improving cardiopulmonary fitness, blood pressure, and body composition. Exercise does not appear to cause or accelerate osteoarthritis. However, counseling concerning warm-ups, stretches, and a graded increase in exercise intensity can help prevent musculoskeletal problems as a side effect of exercise. A 50-year-old woman presents for a follow-up visit to discuss the laboratory results from her annual physical examination and a treatment plan. Her total serum cholesterol level is 260 mg/dl, which is up from 200 mg/dl the previous year. Her blood pressure is 140/100 mm Hg, which is up from 135/90 mm Hg; she weighs 165 lb, a gain of 12 lb from the previous year. Results from other tests and her physical examination are normal. She is postmenopausal and has been receiving hormonal replacement therapy for 2 years. You discuss her increased lipid levels and increased blood pressure in the context of her weight gain and dietary habits. When asked about her dietary habits, she says that she has heard that putting salt on food causes high blood pressure. She asks if she should stop putting salt on her food because her blood pressure is high. How would you describe for this patient the relationship between sodium and hypertension? Tell her that reducing sodium intake usually leads to significant reduc- tions in blood pressure ❏ B. Tell her that reducing intake of sodium and fats while increasing intake of fruits, vegetables, and whole grains usually leads to significant reduc- tions in hypertension ❏ C. Explain to her that decreasing sodium is only important in elderly patients ❏ D. Tell her that research studies are unclear about the role of sodium in hypertension ❏ E. Explain to her that antihypertensive medication is effective in reducing hypertension, making sodium reduction unnecessary Key Concept/Objective: To understand current evidence that supports the relationship between sodium and hypertension The Dietary Approaches to Stop Hypertension (DASH) trial1 demonstrated that the combi- nation of eating fruits, vegetables, and whole grains along with reducing fat and sodium levels can lower systolic blood pressure an average of 11. Reductions in dietary sodium can contribute to substantial reductions in the risk of stroke and coronary artery disease. In addition, for this patient, a reduction in sodium intake will decrease urinary calcium excretion and thus reduce her risk of osteoporosis. Because the patient has asked about putting salt on food, she should also be counseled that 80% of dietary sodium comes from processed food. It is important to review these hidden sources of salt with patients who would benefit from sodium restriction. The average American diet contains more than 4,000 mg of sodium a day. There is no recommended daily allowance for sodium, but the American Heart Association (AHA) recommends that daily consumption of sodium not exceed 2,400 mg, with substantially lower sodium intake for patients with hypertension. Sacks FM, Svetkey LP, Vollmer WM, et al: Effects on blood pressure of reduced dietary sodium and the Dietary Approaches to Stop Hypertension (DASH) diet. A 64-year-old man comes to your clinic for a routine visit. He has a history of myocardial infarction, which was diagnosed 1 year ago. Since that time, he has been asymptomatic, and he has been taking all his medications and following an exercise program. He has been getting some information on the Internet about the use of omega-3 polyunsaturated fatty acids as part of a cardioprotective diet.
