Question: A 16-year-old boy who consulted due to pultulose tonsillitis, fever up to 38.5ºC, painful cervical adenopathies, non-pruritic macular exanthema in the thorax and mild hepatosplenomegaly, 4-5 days old. The Paul-Bunnell test and the IgM for the Epstein-Barr virus are positive. During his admission he develops a continuous fever of up to 40ºC, pancytopenia, icteric hepatitis and coagulopathy of progressive intensity. One week after admission, he was transferred to the ICU due to confusion and respiratory failure. The blood cultures and a urine culture are negative, the CSF is normal and the chest plate does not show infiltrates. Procalcitonin is normal, but PCR and ferritin are very high. From the statements below, what would be the most correct diagnostic and therapeutic approach? 
 Options:  <0> It has a bacterial sepsis of undetermined origin and should be administered ceftriaxone and supportive treatment. <1> It has a bacterial sepsis of undetermined origin and should be administered vancomycin, ceftacidime and supportive treatment. <2> It is an infectious mononucleosis of severe course and glucocorticoids must be administered. <3> It is an infectious mononucleosis of severe course and treatment with acyclovir should be started. <4> Perform a biopsy / aspirate of bone marrow and if hemophagocytosis is confirmed, start treatment with immunosuppressants.

Question: A 27-year-old woman, pregnant for 10 weeks and with persistent severe allergic asthma. Currently, it is adequately controlled with daily inhaled budesonide and inhaled salbutamol at the request of rescue. Go to your consultation concerned about the possible teratogenic effects of your antiasthmatic medication. Which of the following would be the correct attitude? 
 Options:  <0> Since asthma improves during pregnancy in most patients, it is best for the patient and the fetus to discontinue anti-asthmatic treatment. <1> Suspend budesonide because it has been linked to an increased risk of fetal malformations and replace it with an oral antileukotriene (montelukast). <2> Remove the current treatment and replace it with oral prednisone at the lowest possible dose. <3> Maintain the current treatment and reassure the patient about its side effects and the need for adequate control of asthma during pregnancy. <4> Replace budesonide with an anti-IgE monoclonal antibody (omalizumab) for its greater safety in pregnancy as it is not a drug.
