The effects of gender on adolescent suicide in ontario, Canada.

OBJECTIVE: Identify patterns of suicide amongst male and female adolescents aged 11-18 years in Ontario. METHOD: All 370 adolescent suicides in Ontario between January 2000 and November 2006 were analyzed. Previous attempts, history of psychiatric treatment, location committed and method of suicide were assessed. Data was analyzed using 2-tailed t-tests and chi-square without Yates' correction. RESULTS: Male adolescent suicide was twice as common as female suicide. Males were more likely to use violent methods (p=0.0352) and females were more likely to have a history of a previous suicide attempt (p=0.0001). CONCLUSIONS: While most of the data agree with previous studies in adult populations, the ratio of male to female suicides was much lower in our adolescent population.

Nasal spray adherence after sinus surgery: problems and predictors.

OBJECTIVES: To assess patient adherence to nasal spray regimens after endoscopic sinus surgery (ESS) and to study factors that predict adherence. METHODS: A three-arm, randomized, blinded, controlled trial was conducted at a tertiary care academic hospital, studied via a prospective longitudinal survey, of 60 consecutive chronic rhinosinusitis patients managed with ESS and started on one of three postoperative nasal spray regimens. Structured telephone interviews were conducted after surgery over a 12-month period using a validated questionnaire that assessed both spray adherence and barriers to adherence. Patient demographics, time post-ESS, preoperative Sino-Nasal Outcome Test (SNOT) scores, Lund-Mackay scores, adherence risk factors, and polyp grades were used as covariates with logistic regression. RESULTS: Overall, 57.4% of patients were nonadherent. Logistic regression showed that preoperative SNOT scores (p = .018, 95% CI = 0.84-0.98), time post-ESS (p = .016, 95% CI = 1.02-1.22), and the presence of an adherence risk factor (p = .03, 95% CI = 1.18-26.99) significantly predicted whether a patient was adherent and correctly classified 70.4% of all patients. Age, gender, and nasal spray regimen did not predict adherence (p > .05). CONCLUSION: The majority of patients were nonadherent to post-ESS nasal sprays, irrespective of which nasal spray regimen they were on. Preoperative SNOT scores, time post-ESS, and the presence of an adherence risk factor predicted adherence. With this knowledge, otolaryngologists can selectively employ strategies to improve adherence in high-risk patients and possibly improve ESS outcomes.

Peripheral vascular disease: who gets it and why? A histomorphological analysis of 261 arterial segments from 58 cases.

AIMS: This retrospective study aimed to document and illustrate the histomorphological changes underlying peripheral vascular disease (PVD). More specifically, it aimed to analyse and quantify those changes that lead to lower limb amputations. Histological changes were assessed in relation to various clinical pathologies, and significant correlations were sought thereafter. METHODS: A total of 1305 arterial segments were examined from 58 consecutive patients undergoing a lower limb amputation from January 2002 to December 2003. Serial arterial segments were taken from the femoral, popliteal, anterior tibial, posterior tibial, peroneal, and dorsalis pedis arteries, and the degrees of atherosclerotic stenosis and medial calcification were histologically quantified. RESULTS: Atherosclerosis was associated with severe arterial stenosis. An increased occurrence of severe atherosclerotic narrowing coincided with increasing patient age (p = 0.0166), hypertension (p = 0.0019), and diabetes mellitus (p = 0.0036). The presence of medial calcification was an important pathological feature in patients under 70 years of age (p = 0.0308) and significantly more severe in those with diabetes mellitus (p<0.001). CONCLUSION: Atherosclerosis and medial calcification are significant underlying lesions in diabetic patients undergoing lower limb amputation. Medial calcification can cause significant stiffening of the arterial wall and a reduction in its ability to respond to vasodilator stimuli.
