Essential oil production in plants is known to play crucial roles in attractive and defensive
mechanism responses to environmental conditions. Various factors are known to determine the
chemical variability and yields for specific essential oil bearing plants including genetic, physiology
and environment. The purpose of this review is to summarize recent publications on the variation of
essential oil and its composition with regards to physiological aspects of the plants.
Midgut malrotation commonly presents in the neonatal period, and rarely manifests its symptoms in adulthood with an estimated incidence of 0.2-0.5%. Nevertheless, the symptoms are non-specific with no strong pointers towards the clinical diagnosis. Consequently, the diagnosis is usually disclosed with imaging or surgery. We report a case of small bowel obstruction secondary to a congenital peritoneal band with underlying midgut malrotation in a 48-year-old man.
