Spatial distribution of immatures of the banana skipper （Erionota thrax L.） and their parasitisms from three major parasitoids were studied in a Cavendish banana plantation from April 2004 to December 2004. Infestation levels and parasitism of E. thrax life stages were recorded from bunched plants （BP）, flowering plants （FP）, preflowered plants （PF）, broad leaf followers （BLF） and narrow leaf followers （NLF）, as well as on well managed and poorly managed plants. Mean numbers of the immatures and numbers parasitized from the nine blocks in the plantation were fitted to four dispersion indices. Significant numbers of E. thrax immatures and those parasitized by Ooencyrtus erionotae, Cotesia erionotae and Brachymeria albotibialis were recorded from BLF and PF; no eggs were found on BP and FP. Although infestation was higher on well managed plants, only larval parasitism was significantly different. Three of the four indices indicated that eggs and larvae were random while all the indices showed pupae to be clumped. Parasitized eggs and pupae were clumped （4/4 indices） while 3/4 indices revealed a random pattern for parasitized larvae.

Takayasu's arteritis and Crohn's disease are chronic in-flammatory diseases of uncertain aetiology. They rarely occur together, with only twenty nine cases of co-ex-istent Takayasu's arteritis and Crohn's disease reported in the literature. In 88% of these cases, Takayasu's arteritis was diagnosed simultaneously or following a diagnosis of Crohn's disease. We present a case of a young Caucasian medical student, incidentally found to have bilateral carotid bruits on auscultation by a colleague. Magnetic resonance angiography revealed stenoses of the common carotid arteries with estab-lished collaterals, and a diagnosis of Type 1 Takayasu's arteritis was made. An 18F-fluorodeoxyglucose positron emission tomography scan revealed no active disease. Nine months later, she presented with a short history of abdominal pain, vomiting and abdominal disten-sion. Barium follow-through and computer tomography revealed a terminal ileal stricture and proximal small bowel dilation. An extended right hemicoloectomy was performed and histopathology supported a diagnosis of Crohn's disease. This case report is presented with a particular focus on the temporal relationship between these two disease processes and explores whether their concurrence is more than just co-incidence.

Peripheral nerve injury impairs motor, sensory, and autonomic function, incurring substantial financial costs and diminished quality of life. For large nerve gaps, proximal lesions, or chronic nerve injury, the prognosis for recovery is particularly poor, even with autografts, the current gold standard for treating small to moderate nerve gaps. In vivo elongation of intact proximal stumps towards the injured distal stumps of severed peripheral nerves may offer a promising new strategy to treat nerve injury. This review describes several nerve lengthening strategies, including a novel internal fixator device that enables rapid and distal reconnection of proximal and distal nerve stumps.
