At the defense, the student normally opens with an overview statement of the purpose, method, and results of the thesis (15- 20 minutes). Committee members then ask questions, usually in turn, in what turns out to be a relatively informal and lively exchange of ideas, lasting an average of an hour and a half. A student passes with no more than one negative vote. The thesis, as with all Honors coursework, is letter-graded, and the committee may suggest an appropriate letter grade for the student’s work; however, the thesis adviser is responsible for determining and submitting the student's grade.
Note that this brush cytology collection system is not designed to provide the kind of information, specifically cellular architecture, that would be obtained through a punch or incisional biopsy. But it will provide an answer to the question of whether malignancy exists or not, through a quick, minimally invasive, and inexpensive procedure. Should positive results be returned through this system, the brush biopsy must be followed by a conventional biopsy procedure for confirmation. The argument for the brush biopsy is that it eliminates the waiting and watching of a suspicious lesion, while it develops from a highly treatable and curable, early stage localized cancer, into a life-threatening late stage malignancy. Positive identification of oral cancers at the earliest stages, result in the best prognosis for long-term survivability.
The best way to prevent these conditions is to wash your face regularly, keep the skin dry and clean, and to be especially careful of sharing personal items. Borrowing or sharing personal objects from another individual can cause the spread of any fungal infections they may have had. Ringworm is especially contagious, it is of utmost importance to avoid using other people's things, especially those which are very intimate and consistently touch the facial area like headgear or protective masks.
If you do, unfortunately, encounter a facial infection caused by a fungus, there are many ways in which it can be treated. The Office of Women's Health mentions "antifungal cream" as being a treatment for many of these conditions, and the creams can be both prescription and over-the-counter. Otomycosis can be treated with antibiotics, and your doctor may need to suction the area if it has become extremely infected. Pityriasis versicolor can be treated with topical agents like shampoos and lotions, and a person may need to be prescribed antifungal agents for this condition as well. In severe cases, patients may be given oral medications to treat the disorder, but this is rare. It will often take longer for the pigment of the skin to return to normal than it will for the medication to clear the condition itself .
