Association between unilateral quiescent stromal herpetic keratitis and bilateral dry eyes.

PURPOSE: According to our clinical observation, patients with quiescent herpes simplex virus (HSV) stromal keratitis often seem to present with signs of dry eye in the contralateral eye. Our goal was to compare dry eye signs and symptoms in both eyes of patients with quiescent HSV stromal keratitis with those of age- and sex-matched control subjects with healthy corneas. METHODS: A case-control study with 24 subjects per group. RESULTS: The average age of 10 men and 14 women in each group was 58 years. The HSV eye of cases was first compared with the contralateral eye with a healthy cornea. As expected, the HSV eye had a significantly lower corneal sensation threshold (P = 0.001); no significant difference was however found for Schirmer tests done with anesthesia (basal tear secretion) and without anesthesia, tear breakup time, mucus and debris in the tear film, and eyelid margin redness or swelling. Then, the HSV eye of cases was compared with the right eye of controls, whereas the healthy eye of cases was compared with the left eye of controls. Patients with unilateral quiescent HSV stromal keratitis had significantly lower bilateral Schirmer tests both with anesthesia (P = 0.001) and without anesthesia (P = 0.02). Dry eye symptoms of the healthy cornea of cases and those of controls did not differ significantly. CONCLUSIONS: Both eyes of patients with quiescent HSV stromal keratitis in our population were dry even if many patients with HSV stromal keratitis did not have symptoms in their fellow eye.

Factors associated with an individual's decision to withdraw from genetic testing for breast and ovarian cancer susceptibility: implications for counseling.

Our study aimed to examine why individuals withdraw from genetic testing for breast and ovarian cancer susceptibility. We explored the characteristics of 334 individuals from high-risk breast and ovarian cancer families who declined genetic testing for BRCA1/2 mutations, when, and why they did so. Individuals who declined genetic testing were older, and a greater proportion had never developed breast or ovarian cancer. Fifty one per cent (51.1%) of individuals withdrew after the first genetic counseling session. Most of those who declined were afraid of the psychological effects of genetic testing (36.3%). The next most-cited explanations concerned logistic problems such as a limited ability to travel, lack of time, personal issues, advanced age, or health problems (21.7%). The third category included individuals who did not see any advantage in being tested (14.5%). Insurability was a concern (5.9%), mainly for men. Surprisingly, confidentiality was not a frequently reported issue (1.3%). Sixty eight per cent (68%) of individuals belonging to a family in which at least one individual has been tested withdrew after the presence of a deleterious BRCA1/2 mutation in a relative was disclosed, compared to 42% after the disclosure of a nonconclusive test result in at least one relative. Concern about the psychological effects of the result was still one of the major reasons. Several factors may influence an individual's decision to decline genetic testing; a greater understanding of these issues may help health professionals to better meet the needs and concerns of individuals from high-risk families, thus possibly improving their health outcomes.
