    Seizures, metabolic acidosis and coma resulting from acute isoniazid intoxication
    (Australian Society of Anaesthetists, 2005) Topcu I.; Yentur E.A.; Kefi A.; Ekici N.Z.; Sakarya M.
    Isoniazid is an anti-tuberculosis drug, used commonly for treatment and prophylaxis of tuberculosis. Acute isoniazid intoxication is characterized by a clinical triad consisting of metabolic acidosis resistant to treatment with sodium bicarbonate, seizures which may be fatal and refractory to standard anticonvulsant therapy, and coma. Treatment requires admission to the intensive care unitfor ventilatory support, management of seizures and metabolic acidosis. Pyridoxine, in a dose equivalent to the amount of isoniazid ingested, is the only effective antidote. We report the successful treatment of two isoniazid intoxication cases: the case of a child developing an accidental acute isoniazid intoxication and an adult case of isoniazid intoxication with the intent of suicide.

    Evaluating sleep characteristics in intensive care unit and non-intensive care unit physicians
    (Australian Society of Anaesthetists, 2011) Ok G.; Yilmaz H.; Tok D.; Erbüyün K.; Çoban S.; Dinç G.
    Healthcare workers' cognitive performances and alertness are highly vulnerable to sleep loss and circadian rhythms. The purpose of this study was to investigate the changes in sleep characteristics of intensive care unit (ICU) and non-ICU physicians. Actigraphic sleep parameters, Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale and Hamilton Depression Rating Scale were evaluated for ICU and non-ICU physicians on the day before shift-work and on three consecutive days after shift-work. Total sleep time, sleep latency, wakefulness after sleep onset, total activity score, movement fragmentation index, sleep efficiency, daytime naps and total nap duration were also calculated by actigraph. In the ICU physicians, the mean Pittsburgh Sleep Quality Index score was significantly higher than the non-ICU physicians (P=0.001), however mean Epworth Sleepiness Scale scores were not found significantly different between the two groups. None of the scores for objective sleep parameters were statistically different between the groups when evaluated before and after shift-work (P >0.05). However in both ICU and non-ICU physicians, sleep latency was observed to be decreased within the three consecutive-day period after shift-work with respect to basal values (P <0.001). Total sleep time, total activity score and sleep efficiency scores prior to shift-work were significantly different from shift-work and the three consecutive-days after shift-work, in both groups. Working in the ICU does not have an impact on objective sleep characteristics of physicians in this study. Large cohort studies are required to determine long-term health concerns of shift-working physicians.
