Functional outcome after decompression and instrumented arthrodesis in degenerative lumbar spinal stenosis: factors influencing unsuccessful outcome change.

Objective: To determine functional outcome after decompressive laminectomy and instrumented arthrodesis in patients with degenerative lumbar spinal stenosis and identify predictors of failed clinical outcome in these patients.

Material And Method: A retrospective cohort data were collected from January 1999 to February 2004. Degenerative lumbar spinal stenosis patients who had decompressive laminectomy and instrumented fusion with pedicular screw system and completed at least 2 years follow-up were enrolled in the present study.

Pharmacogenetics of cyclophosphamide and CYP2C19 polymorphism in Thai systemic lupus erythematosus.

To assess whether the CYP2C19 polymorphism modified the effect of cyclophosphamide on ovarian toxicity in Thai patients with SLE. We performed a case-control study of female patients with SLE who were treated with cyclophosphamide at Ramathibodi Hospital, Bangkok, Thailand. Cases were patient who had ovarian toxicity (sustained amenorrhoea >12 months or lack of menstruation for >4 months).

An observation study of rapid sequence, awake and sedation-only intubations in an emergency department in Thai patients.

Background: Rapid Sequence Intubation (RSI) in emergency departments (EDs) is recognized as a cornerstone of emergency airway management in developed countries. In Thailand, emergency medicine is a new specialty and RSI is a novel method for patients in EDs. The observation of RSI and two former methods in EDs were carried out to assess whether RSI was more successful and had lower immediate complication in Thai patients or not.

Alcohol, illicit and non-illicit psychoactive drug use and road traffic injury in Thailand: a case-control study.

The objective of this study was to determine the relationship between alcohol use, psychoactive drug use and road traffic injury (RTI). A case-control study was conducted among drivers in Bangkok, Thailand. Two hundred cases and 849 controls were enrolled between February and November 2006.

Prevalence of psychoactive drug use among drivers in Thailand: a roadside survey.

The objective of this study was to determine the prevalence of psychoactive drug and alcohol use among general drivers and predictors of the drug use in Thailand. One thousand six hundred and thirty-five motor vehicle drivers were randomly selected from five geographical regions of Thailand between December 2005 and May 2006. The prevalence of psychoactive drugs was determined using urine tests by gas chromatography/mass spectrometry (GC/MS).
