ABSTRACT

Celebratory use of fireworks has been an integral part of human civilization for over millennia. While the majority of firework use is festive, their explosive nature can result in traumatic injuries and death. The authors present the death of a 21-year-old man found unresponsive on the floor of his parent's garage with extensive damage to his head after an explosion was heard. Firearms could not be found, but there were unexploded homemade and commercially produced firecrackers and components for the manufacture of additional firecrackers. The radial expansion of the blast wave formed by the intraoral explosion of a firecracker created injuries matching those of an intraoral shotgun wound.

ABSTRACT

The constellation of injuries observed in hangings is a subject receiving frequent review in forensic pathology literature. Whereas recent studies have reported high concordance between hangings and internal findings such as strap muscle hemorrhages and hyoid bone and thyroid cartilage fractures, a 2-part study examining autopsied suicidal hangings over a 9-year period at the Wayne County Medical Examiner's Office produced markedly differing results. Retrospectively and prospectively, external and internal autopsy observations were correlated with factors such as age, sex, body height, body mass index, ligature, and height of suspension. In keeping with well-established forensic textbooks, nearly all cases displayed ligature marks and there was strong association between body position and the presence of petechiae. Diverging from contemporary articles, there was a distinctive paucity of internal injuries in both retrospective and prospective portions. Addressing concerns of confirmation bias, assessments confirmed the consistency in identifying and documenting injuries by the pathologists both retrospectively and prospectively.

ABSTRACT

Polyvinyl alcohol functionalized carbon black with H2S-sensor moieties can be pumped through oil and water in porous rock and the H2S content can be determined based on the fluorescent enhancement of the H2S-sensor addends.

ABSTRACT

OBJECTIVE: Safety and tolerability assessment of initiating treatment with a once monthly long-acting injectable form of aripiprazole (aripiprazole once monthly) in patients stabilized on oral antipsychotics other than aripiprazole. METHODS: Patients with schizophrenia treated with oral atypical antipsychotics other than aripiprazole and with a history of aripiprazole tolerability were enrolled. Patients were stabilized per investigator's judgment for ≥14 days on oral atypical antipsychotics during screening. Patients then received one dose of aripiprazole once monthly (400 mg). Concomitant with aripiprazole once monthly, subjects received their current oral atypical antipsychotic for 14 ± 1 days at doses reduced to the mid/lower recommended dose range. Safety and tolerability were assessed for the 28-day treatment phase. For pharmacokinetic analyses, aripiprazole plasma concentrations were measured on Days 7, 14, and 28. RESULTS: Sixty patients were enrolled and initiated with aripiprazole once monthly while continuing treatment with oral olanzapine (n = 3), quetiapine (n = 28), risperidone (n = 24) or ziprasidone (n = 5). Duration of co-administered oral antipsychotic treatment varied, ranging from 0 to 15 days. Treatment was well tolerated. Frequently reported treatment-emergent adverse events (TEAEs) were injection-site pain and toothache (4/60 subjects each, 6.7%), followed by dystonia, fatigue, increased blood creatine phosphokinase, insomnia and restlessness (3/60 subjects each, 5.0%). Most TEAEs occurred in the first 8 days of co-administration irrespective of days of oral overlap. No clinically relevant mean changes from baseline were observed for laboratory values or fasting metabolic parameters. Psychotic symptoms remained stable. Aripiprazole plasma concentrations were similar to those observed following daily doses of oral aripiprazole. CONCLUSIONS: The adverse-event profile of patients receiving aripiprazole once monthly concomitant with oral atypical antipsychotics other than aripiprazole was consistent with previous reports of aripiprazole once monthly concomitant with oral aripiprazole. Adverse events were similar irrespective of prior atypical antipsychotic and duration of oral antipsychotic overlap, suggesting that patients can be safely switched from their existing oral antipsychotic to aripiprazole once monthly without requiring an intermediate stabilization phase with oral aripiprazole. Aspects of the study design (open-label trial and short duration) and patient population (predominantly male and of African-American ethnicity) may limit the generalizability of these findings.

ABSTRACT

OBJECTIVES: The aim of this study was to evaluate the efficacy of aripiprazole in the treatment of discrete symptoms of irritability associated with autistic disorder, as well as other symptoms captured on the Aberrant Behavior Checklist (ABC). METHODS: This was a post hoc analysis of data from two 8-week, randomized, double-blind, multicenter trials to evaluate the efficacy of aripiprazole dosed flexibly (2-15 mg/day, n=47) or fixed (5, 10, or 15 mg/day, n = 166) versus placebo (flexibly dosed, n = 51; fixed dose, n = 52). The effects of treatment on the 58 ABC items were evaluated. RESULTS: Statistically significantly greater improvement was seen with aripiprazole versus placebo (p < 0.05) for all arms in both trials on the ABC-Irritability total subscale score and on the following individual ABC-Irritability items: Mood changes quickly, cries/screams inappropriately, and stamps feet/bangs objects. Several additional items measuring tantrum-like behaviors improved in the flexibly dosed trial and at least one arm of the fixed-dose trial (p < 0.05). Measures of self-injurious behavior, which had low baseline values, demonstrated numerical, but not statistically significant, improvement in both trials. Statistically significantly greater improvement in ABC Stereotypic Behavior and Hyperactivity total subscale scores was also consistent across all arms in both trials. In particular, there was a cluster of items related to hyperkinesis that were consistently sensitive to treatment. CONCLUSIONS: Aripiprazole is efficacious in the treatment of irritability in children and adolescents with autistic disorder, particularly with respect to symptoms associated with tantrum behavior.
