Items 27-29
An 18-year-old white high school student comes to the office in late August because of a stuffy nose for 1 week. He reminds you that he has had severe hay fever in the fall for the past 10 years. Review of his chart shows that he has positive skin tests to ragweed, dust and dust mites, and he is receiving maintenance immunotherapy with extracts of these antigens. He also takes over-the-counter antihistamines for symptomatic relief. This regimen has not provided relief so far this season. Physical examination is normal, apart from clear rhinorrhea. He is afebrile, and there is normal transillumination of the frontal and maxillary sinuses. In reviewing his medical records you note that smears of his nasal mucus contained large numbers of eosinophils. There is no record of any extensive immunologic work-up. You tell him that he now has either an early viral upper respiratory tract infection or the beginnings of his seasonal allergic rhinitis. You suggest that he use a corticosteroid nasal spray plus his usual antihistamines as needed. The appropriate treatment is undertaken, but 4 days later he returns because of a toothache and fever. On physical examination he has right facial fullness and pain below his eye when he leans forward. There is tenderness in the region of the upper premolar and molar teeth on the right side. His temperature is 38.7EC (101.6EF), orally. He has bloody, thick, green mucus coming from his right nostril. The remainder of his physical examination is normal. You suspect maxillary sinusitis on the basis of the clinical findings. 27. Before beginning antibiotic treatment in this patient, it is necessary to first do which of the following? (A) Confirm the diagnosis with CT films of the sinus (B) Confirm the diagnosis with plain x-ray films of the sinus (C) Confirm the diagnosis with transillumination of the sinus (D) Request consultation with a dentist (E) No additional steps are necessary 28. The appropriate steps are taken. In prescribing antibiotic therapy for this patient, it is most important to remember which of the following? (A) Antibiotics are ineffective unless there is a concomitant surgical drainage procedure (B) He is likely to be allergic to penicillin (C) He needs to take medication for more than 7 days (D) Only bactericidal antibiotics are effective (E) Ordinarily at least two antibiotics are given He is treated and initially feels much better. However, soon thereafter he developed a headache, right ear pain and painful stiff neck; he spikes a temperature to 39.3EC (102.7EF), orally. Extraocular movements are normal. 29. Which of the following is the most likely explanation for these new symptoms? (A) Allergic reaction to the antibiotic(s) (B) Associated meningeal inflammation or infection (C) Development of cavernous sinus thrombosis (D) Direct spread of infection from the maxillary to the mastoid sinus (E) Obstruction of the orifice of the maxillary sinus with a mucous plug END OF SET

ой.. я в них немного запуталась...
По поводу второго вопроса: мне кажется, все упирается в давний спор Яны с нашими ЛОР-врачами... и вообще.. все равно остается ощущение, что я недопонимаю акценты или окраску  вопроса, сформулированного на другом языке...

Трудности перевода тоже имеют место.Не всегда понятно ,что собственно от тебя хотят
Все-таки у нас обычно смотрит ЛОР в такой ситуации и решает нужно ли хирургическое вмешательство.

Гм.. по поводу 49 - там описан отек, но ухо "сине-черное" кажется? Если расценивать эту синеву как гематому - напряженные гематомы вскрывают - но ввиду свежей травмы, этого делать нельзя - С
прошу прощения. (в дитях не сильна, но самый operator-dependent метод обследования ИМХО УЗИ)
