Objectives: In the light of increased suicide risk among adolescents, this research aimed at determining the prevalence and severity of suicidal ideations and behaviors of senior high school students in a public secondary school in Metro Manila using the Columbia-Suicide Severity Rating Scale (C-SSRS). Methodology: This is a descriptive cross-sectional school-based study, conducted on 236 senior high school students, 18 years old and above, in San Juan National High School (SJNHS) in San Juan, Metro Manila. The study employed convenience sampling. Upon selection, the C-SSRS was administered. Data on four constructs of suicide were gathered: 1) suicidal ideation severity; 2) intensity, which was quantified in terms of frequency, duration, control, deterrents and reasons for suicidal ideation; 3) suicidal behavior rated on a nominal subscale as actual, aborted, interrupted, preparatory behavior and non-suicidal injurious behavior; and lastly 4) lethality of actual suicide attempts on a 6-point ordinal scale, and if actual lethality was zero, potential lethality was further rated on a 3-point ordinal scale. Results: The majority (67.8%) had mild suicidal ideations; 37.71% had active suicidal ideations with intent but not necessarily a specific plan and only 13.98% had active suicidal ideation with intent to act and a specific plan. The intensity of suicidal ideation was not that frequent in 35.59% of the respondents i.e.18.64% 1x/ week and 16.95% less than 1x/ week. About a third (30.07%) had very short duration of suicidal ideations i.e. fleetingly (19.92%) or less than an hour/ day (11.02%). A third (32.62%) were able to easily control (18.64%) or control with minimal difficulty (13.98%). Reason for suicidal ideation were either to get attention (10.59%) or to end the emotional pain (11.02%). A third (30.93%) had actual attempts (15.25%) and Non -Suicidal Self Injury (NSSI) (15.68%); while another 35.06 % had interrupted (16.53%) or aborted (19.07%) attempts. Those who had actual attempts, 41.67% had no physical injury while 50 % incurred minor injuries. Thirty- two (88.89%) had suicidal attempt that was likely to result in injury but not likely to cause death. Conclusion In light of these relatively high prevalence rates for suicidal ideation and behaviors, schoolwide intervention on education or awareness programs, gatekeeper training, peer leadership, skills training and screening or assessment may have to be instituted to curb the increased suicide risk of the senior high school students and further prevent suicide attempts.

Objective: To describe changes in the retinal-nerve-fiber layer (RNFL) in patients diagnosed with ethambutol toxic optic neuropathy (ETON) using optical coherence tomography (OCT). Methods: Ophthalmological examinations were performed in 3 patients diagnosed with ETON. Visual acuity (VA), contrast sensitivity, color vision testing, slitlamp examination, applanation tonometry, dilated funduscopic examination, fundus and disc photography, automated perimetry and OCT were performed. Results: Three patients with ETON had VA ranging from 20/150 to counting fingers (CF). They were unable to resolve contrast sensitivity and discriminate fingers (CF). TWo patients with VA of CF in both eyes had RNFL thinning of 48.8% and 49.5%. A third patient 3 with VA of 20/150 in both eyes showed RNFL thickening of 14.10%. Conclusion: The results suggest that OCT may be useful ancillary procedure in early detection and monitoring of ophthalmological changes due to ETON.
