Massive gastropathy due to gallstone obstruction of the duodenum (Bourveret syndrome).

Gallstones are common in the general population and are often asymptomatic, but they can also cause complications such as cholecystitis and pancreatitis. In rare instances, they can lead to the formation of a cholecystoduodenal fistula and gallstone ileus. Gastric dilatation and distension following gallstone ileus are extremely uncommon and have rarely been reported in the literature.

Neuropsychiatric correlates of olfactory identification and traumatic brain injury in a sample of impulsive violent offenders.

Background: Olfactory deficits have a diverse etiology and can be detected with simple olfactory tests. Key olfactory pathways are located within the frontal and temporal lobes where they are vulnerable to damage due to head trauma. Orbitofrontal cortex (OFC) integrity is important for olfaction and aspects of behavioral regulation.

Self-reported traumatic brain injury in a sample of impulsive violent offenders: neuropsychiatric correlates and possible "dose effects".

Background: Traumatic brain injury (TBI) is a major public health problem that may be associated with numerous behavioral problems, including impulsivity, aggression and violence. Rates of self-reported TBI are high within offender populations, but the extent to which TBI is causally implicated in causing illegal behavior is unclear. This study examined the psychological and functional correlates of histories of traumatic brain injury in a sample of impulsive violent offenders.

Olfaction and Executive Cognitive Performance: A Systematic Review.

Objective tests of olfaction are widely available to aid in the assessment of olfaction. Their clearest role is in the characterization of olfactory changes, either reported by or suspected in a patient. There is a rapidly growing literature concerned with the association of olfactory changes with certain neuropsychiatric conditions and the use of olfactory testing to supplement conventional assessments in clinical and research practice is evolving.

Level and determinants of knowledge of symptomatic knee osteoarthritis among railway workers in Malaysia.

Background: Symptomatic knee osteoarthritis, an ancient malady greatly impairing modern population quality of life, has stimulated global attention to find effective modes of prevention and intervention.

Purpose: This study aimed to assess factors affecting knowledge of symptomatic knee osteoarthritis (knee OA) among Malaysian railway workers.

Methods: A cross-sectional study was conducted among 513 railway workers involving eight major states within Peninsular Malaysia using population-based sampling.
