Two-Year Outcome of Partial Lacrimal Punctal Occlusion in the Management of Dry Eye Related to Sjogren Syndrome

Purpose: To analyze the influence of thermal partial punctal occlusion on the ocular surface of dry eye related to Sjogren syndrome. Material and Methods: Thirty-seven eyes of 19 patients (3 male and 16 female; 49.11 +/- 14.33 years old) with keratoconjunctivitis sicca were enrolled in this study. Superior and inferior partial occlusion were performed in both eyes under topical anesthesia using thermal cautery with a sterile tip to obtain lacrimal punctum smaller than 0.5 mm. Schirmer I, break-up-time, diameter of lacrimal puncta, corneal fluorescein, and rose Bengal staining scores were analyzed before and after 24 weeks and after 24 months of the procedure. All measurements were performed under controlled climate. Results: The average lacrimal punctum diameter before the procedure was 0.65 +/- 0.134 mm. All lacrimal puncta were successfully reduced to less than 0.5 mm after 4 weeks of the procedure. The average Schirmer I test values improved statistically after 24 weeks and maintained stable after 24 months. Average break-up-time, rose Bengal, and fluorescein staining score values improved statistically after 24 weeks and improved even more after 24 months. Average Schirmer I test, break-up-time, rose Bengal, and fluorescein staining scores showed significant improvement (p < 0.0001) after 24 months of partial thermal punctal occlusion. Conclusion: Our study showed that reducing the punctum diameter to 0.5 mm can improve vital staining scores, break-up-time, and Schirmer I test in dry eye related to Sjogren syndrome.

Ethical Conflicts over the Management of Transsexual Adolescents-Report of Two Cases

Introduction. The diagnosis and the treatment of transsexualism, particularly during adolescence, generate considerable discussion among specialists. Many health and legal professionals have not yet reached a strong consensus on medical treatment for juvenile transsexuals. Hormonal therapy cannot only represent a medical procedure to adjust the somatic sex to the psychological gender, but can also be a reasonable means of preventing some juvenile transsexuals from engaging in undesirable and risky behavior. Aim. To report the cases of two transsexual adolescents who resorted to prostitution to afford hormonal medications when treatment was denied because of age criteria. Results. Hormonal medications were not recommended by the endocrinology staff because specific laws regulating this medical procedure for juvenile transsexuals in Brazil are lacking. In response, these adolescents chose to use illegally obtained sex hormones to treat themselves. Conclusions. We propose ""harm reduction"" as a means of coping with this dilemma in some cases.

Presence of tropical spastic paraparesis/human T-cell lymphotropic virus type 1-associated myelopathy (TSP/HAM)-like among HIV-1-infected patients

Human immunodeficiency virus type 1 (HIV-1) and human T-cell lymphotropic virus types 1 and 2 (HTLV-1 and -2) are retroviruses that share similar routes of transmission and some individuals may have a dual infection. These co-infected subjects may be at increased risk for tropical spastic paraparesis/HTLV-1-associated myelopathy (TSP/HAM)-like. To study the prevalence of tropical spastic paraparesis/HTLV-1-associated myelopathy (TSP/HAM) among coinfected HIV-1/HTLV-1 subjects. Since July 1997, our group has been following a cohort to study the interaction of HTLV with HIV and/or hepatitis C virus (HCV), as well as HTLV-1-only infected asymptomatic carriers or those already presenting with TSP/HAM. During these 9 years, 296 HTLV-1-infected individuals were identified from a total of 538 patients who were referred to our clinic at the Institute of Infectious Diseases ""Emilio Ribas,"" in Sao Paulo, Brazil. All subjects were evaluated by two neurologists, blinded to the HTLV status. TSP/HAM diagnosis was based on Kagoshima diagnostic criteria. Results: A total of 38 HIV-1/HTLV-1 co-infected subjects were identified in this cohort: Twenty-six had already been diagnosed with AIDS and 12 remained asymptomatic. Six of 38 co-infected subjects (18%) were diagnosed as having TSP/HAM and also AIDS, and for 5 of them TSP/HAM was their first illness. One additional incident case was diagnosed after 2 years of follow-up. No modifications on HIV-1 viral load was seen. In contrast, the co-infected with TSP/HAM-like group showed higher HTLV-1 proviral load (505 +/- 380 vs. 97 +/- 149 copies/10(4) PBMC, P= 0.012) than asymptomatic co-infected subjects, respectively. The incidence of myelopathy among HIV-1/HTLV-1 co-infected subjects is probably higher than among patients infected only with HTLV-1, and related to a higher HTLV-1 proviral load. Thus, HTLV-1/2 screening should be done for all HIV-1-infected patients in areas where HTLV-1 infection is endemic.
