C) III
Serum sickness is an example of type III hypersensitivity. This type requires formation of antibodies, usually IgG or IgM, against soluble antigens. Complexes of antigens and antibodies are then deposited in tissues, primarily the joints, kidneys, and lung vascular endothelium. Serum sickness involves inflammation due to activation of complement and leukocytes inside the tissues.

What does the diagnosis paresthesias mean?
Procedure: Lumbar puncture Indication: Paresthesias Procedure: Prior to the procedure, the relevant films were reviewed. Informed consent was obtained from the patient. The patient was placed on the procedure table in prone position. The lower spine was examined with fluoroscopy. The area was then marked. The L3–L4 area was then prepped and draped in the usual fashion using chlorhexidine swab. Approximately 5 cc of 1 percent lidocaine was then used to anesthetize the area. A 20-gauge, 10 cm spinal needle was then advanced under direct fluoroscopic guidance into the thecal sac. The stylette was then removed, demonstrating adequate CSF backflow. Opening pressure was approximately 115 cm of water. Approximately 24 cc of fluid was removed without complication. Closing pressure was about 75 cm of water. Needle was then removed and bandage applied. 0.3 minutes of fluoroscopy time were utilized. The patient was instructed to lie in the horizontal position for at least 2 hours to decrease risk of spinal headache.
