38. hyperventilation causes a mild respiratory alkalosis and is experienced as acral and periorbital dysesthesias.(tingling sensation in the fingertips.)

39.Remember treatment of CMV retinitis in HIV if Gancyvlovier dosen't work is FOSCARNET(can cuase renal toxicity).

40.Asperger disorder it's characterized by defecits in interpersonal development,restricted patterns of interest&behaivior,and normal cognitive and speech development.

41.Spondylolysis is a defect seen in the pars interarticularis portion of the lamina.Spondylolysis is believed to be caused by repeated microtrauma, resulting in stress fracture of the pars interarticularis. Heredity also is believed to be a factor. Patients with spina bifida occulta have an increased risk for spondylolysis. Approximately 95% of cases of spondylolysis occur at the L5 level.Athletes who participate in sports, such as soccer, baseball, football, wrestling, gymnastics, and tennis, are more likely to have symptomatic spondylolysis at some point(with hyperextension maneuvers)

42.Patients with suspected spondylolysis should be evaluated initially with plain radiography, consisting of anteroposterior, lateral, and oblique views of the lumbar spine. The lateral views are most sensitive for detection of pars fractures, and the oblique views are most specific.

43..Remember The sudden onset of tachycardia and hypotension in a patient who is being mechanically ventilated with positive pressure, is at increased risk of a bullous rupture from barotrauma, leading to a pneumothorax.

44. young age, occurrence of pain at night, negativity of rheumatoid factor, and especially, bilateral involvement of sacroiliac joints are consistent with ankylosing spondylitis.
