Prescription Opioid Misuse Index in sickle cell patients: A brief questionnaire to assess at-risk for opioid abuse.

OBJECTIVE: To develop a survey instrument to identify adult sickle cell disease (SCD) patients on chronic opioid therapy who are at-risk for opioid abuse. DESIGN: Prospective survey and interview. SETTING: Adult SCD clinic in a large urban teaching facility. PATIENTS/PARTICIPANTS: Convenience sampling of adult patients presenting to the sickle cell clinic. INTERVENTIONS: None. MAIN OUTCOME: Primary outcome was "at-risk for opioid misuse," defined as at least 3/8 "yes" answers (a positive composite score) on the Prescription Opioid Misuse Index (POMI) questionnaire. Secondary outcome was DSM-IV criteria for substance abuse using the DSM IV Diagnostic Interview Schedule. RESULTS: Of the 99 patients who completed the POMI, the mean age was 36 years; 58.6 percent were female, 48 percent were hemoglobin SS (47/99), and 26 percent were SC (26/99). Twenty-four percent (24/99) were identified as at-risk for opioid misuse using the POMI. There were no differences in demographic, SCD genotype, or socioeconomic variables for at-risk versus not-at-risk patients. CONCLUSION: Twenty-four percent of unselected adult SCD patients on opioids were identified as at-risk for opioid misuse using a quick survey. This may represent as much as 2.5-7 times the national misuse rate. This group of patients may benefit from additional diagnostic and therapeutic interventions to help understand and manage their opioid usage.

Adult Status Epilepticus: A Review of the Prehospital and Emergency Department Management.

Seizures are a common presentation in the prehospital and emergency department setting and status epilepticus represents an emergency neurologic condition. The classification and various types of seizures are numerous. The objectives of this narrative literature review focuses on adult patients with a presentation of status epilepticus in the prehospital and emergency department setting. In summary, benzodiazepines remain the primary first line therapeutic agent in the management of status epilepticus, however, there are new agents that may be appropriate for the management of status epilepticus as second- and third-line pharmacological agents.

Intracellular secretory leukoprotease inhibitor modulates inositol 1,4,5-triphosphate generation and exerts an anti-inflammatory effect on neutrophils of individuals with cystic fibrosis and chronic obstructive pulmonary disease.

Secretory leukoprotease inhibitor (SLPI) is an anti-inflammatory protein present in respiratory secretions. Whilst epithelial cell SLPI is extensively studied, neutrophil associated SLPI is poorly characterised. Neutrophil function including chemotaxis and degranulation of proteolytic enzymes involves changes in cytosolic calcium (Ca(2+)) levels which is mediated by production of inositol 1,4,5-triphosphate (IP3) in response to G-protein-coupled receptor (GPCR) stimuli. The aim of this study was to investigate the intracellular function of SLPI and the mechanism-based modulation of neutrophil function by this antiprotease. Neutrophils were isolated from healthy controls (n = 10), individuals with cystic fibrosis (CF) (n = 5) or chronic obstructive pulmonary disease (COPD) (n = 5). Recombinant human SLPI significantly inhibited fMet-Leu-Phe (fMLP) and interleukin(IL)-8 induced neutrophil chemotaxis (P < 0.05) and decreased degranulation of matrix metalloprotease-9 (MMP-9), hCAP-18, and myeloperoxidase (MPO) (P < 0.05). The mechanism of inhibition involved modulation of cytosolic IP3 production and downstream Ca(2+) flux. The described attenuation of Ca(2+) flux was overcome by inclusion of exogenous IP3 in electropermeabilized cells. Inhibition of IP3 generation and Ca(2+) flux by SLPI may represent a novel anti-inflammatory mechanism, thus strengthening the attractiveness of SLPI as a potential therapeutic molecule in inflammatory airway disease associated with excessive neutrophil influx including CF, non-CF bronchiectasis, and COPD.
