BACKGROUND Over the course of the past 40 years, there have been a significant number of changes in the way in which lymphomatous disease is diagnosed and managed. With the advent of computed tomography, there is little role for staging laparotomy and the surgeon's role may now more diagnostic than therapeutic. AIMS To review all cases of lymphoma(More)
INTRODUCTION Langerhans' cell histiocytosis is a collective term used to describe a group of enigmatic proliferative disorders. The natural history of the disease varies from a slow, benign, localized symptomatic bony or soft tissue lesion, to a rapidly progressive widespread multiple organ disorder which is often fatal. Eosinophilic granuloma accounts for(More)
INTRODUCTION Orbital emphysema is a recognised complication of fractures of the orbit and only rarely poses a threat to vision. PATIENTS AND METHODS We present three patients with threatened vision secondary to orbital emphysema that required an immediate surgical decompression. RESULTS Visual function was preserved in all three patients. CONCLUSION(More)
The physiological and physical principles involved in the management of facial lacerations are reviewed. Because there have been no previously published descriptions of the actual problems encountered in clinical practice in A & E Departments, a prospective clinical survey of 100 consecutive patients with facial lacerations repaired by oral & maxillofacial(More)
Giant orf is a zoonotic infection that is endemic in sheep and goats. It may be transmitted to humans by direct contact with infected animals or contaminated objects and is typically found on the hands. We report the case of a sheep farmer with facial orf that proliferated dramatically with the formation of satellite lesions after curettage.
New measurements of the electrophoretic mobility of T-cell model systems have been carried out and analyzed to obtain the dynamic variation in mobility in small titration increments during separate upscale and downscale sweeps in pH. We demonstrate that a plot of plambda vs p[NaCl] has been found essential in evaluating the consistency of electrophoretic(More)
New measurements of the dependence of the surface charge on the pH and electrolyte concentration for three living human white blood cell lines that are the principal targets of the HIV-1 virus are reported. Comparison of the electrophoretic fingerprint (EF) pattern, especially the line of zero mobility, with that of reference colloids establishes the(More)
An electrophoretic fingerprint of a CD4+ T-cell (H9) has been produced for the first time. Samples were taken from three separate cultures prepared at different times to obtain a general characterization of the cells. The availability of commercial instrumentation equipped with an auto-titrator has made possible the application of both the 2-dimensional and(More)
Bilateral mandibular coronoid hyperplasia is a rare cause of restricted mouth opening. Diagnosis of the condition prior to general anaesthetic is essential, as oral intubation may be impossible. The reported case illustrates the role of computed tomography in assessment of the disorder and effective treatment by coronoidectomy.
