Testing Midstream Urine for Chlamydia trachomatis |

Midstream samples might be adequate for evaluating both chlamydial and urinary tract infections, but study results were not definitive.
First-void urine samples are recommended for diagnosing chlamydia with nucleic acid amplification tests, whereas midstream specimens are used for sediment evaluation and bacterial culture. Might midstream samples be sufficient for both purposes? In a New Zealand study, women with known chlamydial infections (based on positive vaginal swabs) collected concomitant first-catch and midstream urine samples; researchers then calculated the sensitivity of midstream urine specimen testing for detection of Chlamydia trachomatis.

Epilepsy and TBI May Increase Risk for Violence |
|
|

Written by Myette

This population-based study suggests that substance use and developmental factors also play a role.
Aggressive behavior and agitation, which sometimes occur in neuropsychiatric disorders, have an unclear link to violent crime. Researchers examined associations between convictions for violent crime in 1973–2009 and earlier diagnoses of epilepsy or traumatic brain injury (TBI), identified in hospital inpatients or outpatients in Sweden. The study population comprised 22,947 epilepsy patients and 22,914 TBI patients, each matched by age and sex to 10 controls (birth years, 1958–1994). Separate analyses of unaffected siblings were conducted.
