Externalizing and internalizing syndromes in relation to school truancy among adolescents in high-risk urban schools.

INTRODUCTION: To examine the relationship between externalizing/internalizing syndromes and school truancy among Form Four (10th grade) students attending "high-risk" schools in Kuala Lumpur. METHODS: This is a cross-sectional study conducted upon 16-year-old adolescents attending three high-risk schools in Kuala Lumpur. A total of 373 students completed self-administered questionnaires on the sociodemographic variables and externalizing/internalizing syndromes. The number of truant-days per student during the study period was obtained from the school records. RESULTS: The mean internalizing score, externalizing score and total problem score of those who were truant were found to be significantly higher (P < 0.05) than those who were non-truant. Multiple logistic regressions showed externalizing syndrome (odds ratio [OR] = 1.044; confidence interval [CI] = 1.012-1.078, P = 0.018) significantly predicts truancy but not the internalizing syndrome. Two other psychosocial factors, namely, having divorced parents (OR = 2.495, CI = 1.058-5.886, P = 0.037) and did not understand or were uncertain of the purpose of schooling (OR = 2.621, CI = 1.265-5.433, P = 0.010) were also showed to be stronger predictors of truancy compared to externalizing/internalizing syndromes. DISCUSSION: Truancy has significant association to externalizing syndrome, in addition to other significant psychosocial variables like parental and schooling factors. This finding indicated the need for comprehensive assessment of students presenting with truant behavior, including the identification of associated psychological and behavioral problems which highlights the roles of mental health professionals in tackling truancy.

Vincristine-induced vocal cord palsy: case report and review of the literature.

Vincristine-induced vocal cord paralysis is a rare but serious complication. We report 2 patients with acute lymphoblastic leukemia who developed progressive stridor during induction chemotherapy. There were no clinical features of peripheral or autonomic neuropathy. Flexible laryngoscopy confirmed the diagnosis of bilateral vocal cord palsy; interestingly, the nerve conduction test revealed axonal motor neuropathy involving the median and common peroneal nerves in both patients. The first patient required prolonged ventilatory support necessitating unilateral cordectomy before extubation, whereas the second only required supplemental oxygen therapy. There was resolution of stridor in the first patient after cordectomy and gradual clinical improvement in the second. These cases illustrate that a high index of suspicion of vincristine-induced vocal cord palsy with prompt otolaryngology consultation for laryngoscopy is required in the diagnostic evaluation of a patient who has received vincristine.
