Please answer Questions 1–9 based on the following scenario: You were recently appointed as the Medical Director for the Hemostasis Laboratory at your hospital. You would like to evaluate the possibility of perform- ing the assay in your laboratory. You have several options for this assay, including several commercially available kits, as well as an in-house developed assay. Waived tests (Answer A) are defned as “simple laboratory examinations and procedures that have an insignifcant risk of an erroneous result. It is also responsible to promote healthy and safe behaviors and to train the public health workforce, including disease investigators. Based on the information, at what point (A,B,C,D or E) will the commercial assay give you the most diagnostic accuracy (i.

A defciency in selenium has been described to affect the immune system and to have an effect on the ability to control the infection (Harbige generic 100 mg zithromax mastercard zombie infection android, 1996; Kukreja and Khan buy zithromax 500 mg free shipping antibiotic resistance review, 1998). Thus, selenium defciency is involved in a higher host susceptibility to Cryptosporidium parvum infection (Wang et al. Likewise, selenium defciency in rats and mice has been shown in in vitro studies to alter the ability of neutrophils and peritoneal macrophages to eliminate Candida albicans. For other studies that have been conducted investigating the relation between sele- nium and different bacterial infections, defciency of this trace element increases the persistence of Listeria monocytogenes in the intestine and mesentery lymphoid nodules (Wang et al. By contrast, the removal of species such as Salmonella typhimurium and Staphylococcus aureus is not related to selenium defciency (Boyne and Arthur, 1986; Boyne et al. Changes in the intracellular environment that are induced by alterations in micro- nutrient status can directly infuence viral virulence and can cause immune sys- tem dysfunction. Thus, selenium defciency is able to promote the mutation of a virulent strain of coxsackievirus in the heart to a strain that causes myocarditis, when the virus is passed from the selenium-defcient to a nutritionally adequate host. This pathology is an endemic disease in China, which is called Keshan disease, a cardiomyopathy characterized by necrotic lesions throughout the myocardium accompanied by cellular infltration and calcifcation. Indeed, the administration of selenium to individuals from defcient areas is able to prevent the disease. In the same way, Se-defcient mice were more susceptible to infuenza virus infection than Se-adequate mice (Beck et al.

Afer performing a his- tory and physical and ensuring that the patient has a peripheral seventh nerve palsy, you believe the most likely diagnosis is Bell’s palsy. T e patient is very concerned about his face and asks if there is anything you can do to improve his condition. Suggested Answer: Bell’s palsy is an idiopathic condition with possible viral and autoimmune etiologies. T e patient does not have any signifcant contraindications to corticosteroid therapy, such as poorly controlled diabetes, and so he should be started on prednisolone 25 mg twice daily, or an equivalent dosing of another cortico- steroid. In the absence of specifc viral diagnoses, such as herpes zoster reactivation, the addition of antiviral therapy for the treatment of facial nerve palsy remains considerably more controversial. However, a modest efect has not been entirely excluded, and physicians may consider adding antiviral therapy in certain clinical situations. Overall, the patient can be reassured about the good prognosis of his condition based on the high per- centage of patients with complete recovery of facial nerve function afer pred- nisolone treatment.
