A 24-year-old woman presents to the clinic with fatigue generic cytotec 200 mcg mastercard, fever buy cytotec 200 mcg on-line, sore throat, and puffy eyes. On exami- nation, she is found to have lymphadenopathy and mild hepatosplenomegaly. How would you interpret a positive heterophile antibody test result in this patient? Heterophile antibody testing would not be helpful for this patient, because the results may be positive owing to her previous episode of mononucleosis B. She has acute infectious mononucleosis from primary EBV C. A positive result indicates moderate to severe clinical disease E. She has acute rheumatoid arthritis Key Concept/Objective: To understand the use of heterophile antibodies in the diagnosis of EBV mononucleosis 88 BOARD REVIEW More than 90% of adolescents and adults with primary infectious mononucleosis test positive for heterophile antibodies. The monospot test is commonly used to test for het- erophile antibodies. Patients test positive for 3 to 4 months after the onset of illness, and heterophile antibodies may persist for up to 9 months. Although CMV mononucleosis is often difficult to differentiate clinically from other forms of mononucleosis, patients with other forms of mononucleosis rarely test positive for heterophile antibodies. The heterophile titer does not correlate with the severity of the illness. A 24-year-old man presents to the emergency department complaining of headache, fever, nausea, and photophobia. On examination, the patient has a temperature of 101° F (38. A non–contrast-enhanced CT scan of the head shows no evidence of bleeding, trauma, or mass effect. Which of the following cerebrospinal fluid profiles is most consistent with aseptic meningitis associ- ated with enteroviral infection? In addition, aseptic meningitis is the most common central nerv- ous system illness associated with enteroviruses.

Differential diagnosis The perception of loss or altered smell may be actually due to altered taste secondary to dysfunction in the glossopharyngeal nerve (CN IX) order 100 mcg cytotec. Therapy Therapy depends upon etiology and in cases of trauma is usually supportive purchase cytotec 200 mcg on line. Prognosis When the loss of smell is due to trauma, more than one third of individuals have full recovery within 3 months.

T Tumor Special sensory: visual information from the retina Quality Light energy is transduced into electrical signals in the posterior layer of the Anatomy retina by receptor cells called rods and cones. Primary sensory neurons called bipolar cells receive signals from the rods and cones. Bipolar cells pass these signals onto secondary sensory neurons called ganglion cells, which are found in the most anterior layer of the retina. The axons of the ganglion cells traverse the retina and converge at the optic disc near the center of the retina.

The red light is less effective at photoactivating Liquid Nitrogen porphyrins, but penetrates more deeply into tissue.
