"The following two pictures are from the evaluation of a 34 year old man. He complains of chrionic cough, fever and weight loss. He claims to be gay, but says he is very careful about his sexual contacts.<p>The first image is his chest X-Ray and the second is a silver stain of a bronchial specimen.<p>The most likely diagnosis is<p><IMG SRC=que1a.jpg><p><IMG SRC=que1b.jpg>$$cytomegalovirus%%Kaposi sarcoma^^Cryptosporidium&&Pneumocystis",
"The 34 year old man in the previous question most likley$$has been HIV positive for no more than 6 months%%has a peripheral T-4 count of less than 200^^should be quarantined&&should receive immediate immunoglobulin ijections",
"A newborn with a significant congenital rubella infection may have cord blood containing elevated levels of$$IgG%%IgA^^IgG and IgM&&IgG and IgE",
"A 26-year old man suffered an open fracture of the femur in a construction accident. The leg wound became infected with Staphylococcus aureus. After antibiotic therapy was initiated, the patient's temperature and leukocyte count fell, but the next day he developed fever, chills, and hematuria. A blood count indicated that his hematocrit and hemoglobin had fallen from 40% and 14 g/dl to 35% and 11.5 g/dl in two days. A direct Coomb's test was positive.<p>The most likely explanation of events described is$$recrudescence staphylococcal infection%%hypersensitivity reaction to the antibiotic^^late bleeding into the fractured femur&&systemic lupus erythematosus",
"Antinuclear antibodies are$$seen in a small percentage of older individuals in the absence of disease%%diagnostic of autoimmune disease^^specific for systemic lupus erythematosus&&directed only at the nucleic acids present in cell nuclei",
"Type IV hypersensitivity is involved in all of the following except$$autoimmune disease%%peneumococcal pneumonia^^transplant rejection&&influenza infection",
"The ELISA, enzyme linked immunosorbent assay, is a sensitive test for antibody to HIV. Which of the following statements is true?$$a positive ELISA must be confirmed by a specific test such as a western blot%%the ELISA screening test for HIV is 100% specific^^the ELISA screening test for HIV is 100% sensitive&&the ELISA is a sensitive test during the window period of HIV infection",
"HISTORY: This 12-year-old male elementary school student was admitted to the hospital complaining of swelling of the face, pallor and lethargy of four days duration. One month prior to admission he had experienced painful swelling of his cervical lymph nodes associated with an erythematous rash and fever.  He was treated at home with aspirin. Several of his close friends had complained of severe sore throats at about this same time.<p>PHYSICAL FINDINGS: BP-140/90 mm Hg; slight pitting edema of ankles and puffiness of face.<p>LABORATORY RESULTS: WBC-12,000/mm3 (nl: 4,000-11,000/cu mm) with 83% neutrophils urinalysis-reddish brown with 1+ protein, more than 100 RBC/hpf, RBC casts, 25 WBC/hpf BUN-75 mg/dl (nl: 8-25 mg/dl); serum creatinine-5 mg/dl (nl: 0.5-1.2 mg/dl).<p>Which of the following is MOST PROBABLY involved in the pathogenesis of this disease?<p>The following picture is a glomerular immunofluorescent pattern with IgG antibody. It represents<p><IMG SRC=que7.gif>$$type I hypersnestivity reaction%%type II hypersnestivity reaction^^type III hypersnestivity reaction&&type IV hypersnestivity reaction",
"The following two photographs are of a 48 year old woman who describes symptoms of arthritis, dysphagia and pain in her fingers following exposure to cold. Antibody tests show a positive ANA, postive Anti-Scl 70 and positive anticentromere antibody.<p>The most significant systemic aspect of this disease is most likley to be<p><IMG SRC=que9a.jpg><p><IMG SRC=que9b.jpg>$$an acquired bleeding tendency%%panus formation in the joints^^ocular infections&&intimal fibrosis of the microvasculature",
"The following picture is of a surgical specimen of a woman who had noted slight enlargment of the anterior aspect of her neck. She was euthyroid.<p>The surgeon described the specimen as grey and rubbery.<p>Another diagnostic test of help would be<p><IMG SRC=que10.jpg>$$a creatinine clearance%%thyroid antitmicrosomal antibodies^^analysis for Philadelphia chromsome on the peripheral blood&&lateral X-Ray view of the skull to assess sella turcica"
