Purpose The purpose of this research was to evaluate the outcomes, specifically diplopia and enophthalmos, as well as the complications of surgical repair of orbital fractures using the transconjunctival surgical approach. Methods A cross-sectional descriptive study was conducted. Thirty patients who underwent surgical repair of an orbital fracture were included in this case series. All patients were operated using the transconjunctival surgical approach and in all cases the fracture was repaired with 0.4 mm nylon foil sheeting (Supramid). The preoperative and postoperative clinical findings of visual acuity, diplopia and enophthalmos were analyzed, and postoperative complications were noted. Results Twenty-five of 30 patients (83%) presented with diplopia preoperatively and two patients (7%) had persistent diplopia postoperatively. Enophthalmos of greater than 2mm was present in 16 of 30 patients (53%) preoperatively and five patients (17%) had persistent enophthalmos postoperatively. All patients with persistent postoperative diplopia and or enophthalmos underwent late surgical repair (mean 10.6 months). Ten patients (33%) in this series were repaired early, within three weeks of trauma, and had no diplopia or enophthalmos postoperatively. There were no cases of lower lid retraction or ectropion. There was one complication related to the nylon foil. Conclusion The transconjunctival surgical approach used to repair orbital fractures was associated with good functional outcomes and few complications. Early surgical repair of orbital blowout fractures and the use of nylon foil sheeting are supported by this case series.

This study was designed to gather information about the nature and content of post-surgical play behaviour displayed by hospitalized pre-school children. Four questions were explored: Are common themes expressed in the play behaviour of hospitalized pre-school children after major surgery? Does the quality and intensity of the play behaviour demonstrated by pre-school children follow a similar pattern? Will pre-school children use play therapy as a medium through which to express fears and concerns about their hospital experience? Do children tend to act out their perceptions of what has happened to them in hospital? The population selected for the study were four girls and one boy between the ages of three and five years, who were admitted for major surgery on the heart or great vessels. During the recovery period after surgery each child had the opportunity to take part in at least five play therapy sessions lasting approximately one hour each. Play therapy took the form of situational play using real or simulated hospital equipment and various dolls representing children and adults. Each child chose the direction and content of play. The investigator took part in play as directed by the child. Parents could join in if they wished. The verbal and non-verbal behaviour displayed by each child during play therapy was recorded by audio tape and by process recordings. Four out of five children in the study participated actively in play therapy. In the course of play they expressed five common themes: intrusive procedures; re-enactment of procedures; testing reality; autonomy: regaining control; separation from home and family; and nurturing activities. The quality and intensity of the children's play behaviour followed a pattern from intense to more relaxed and from aggressive to more gentle play. During play each child expressed some individual fears and concerns about his hospitalization. Intrusive procedures were the most frequent topic of play for all the children. Finally, each child tended to act through specific procedures so that play behaviour became a factual account of the child's hospital experience. One child, the only boy in the study, did not want to participate in play therapy. The reasons for this were not investigated. It was concluded that play therapy is a useful technique which can assist nurses understand the pre-school child's perception of his hospital experience. Play therapy also has potential as a therapeutic intervention to help a child come to terms with the traumatic events of his hospitalization. / Applied Science, Faculty of / Nursing, School of / Graduate

The mast cell is one of the few outposts of the body to which, as yet, no definite function has been attributed. These cells, with their numerous coarse basophilic metachromatic granules, are classified into two groups, firstly, the blood mast cells, or mast leucocytes, or basophils, and secondly, the tissue or histogenous mast cells. Modern authorities agree that the only common feature possessed by these two groups, aside from their name, is the basic metachromatic staining reaction of their granules.
Progress in surgical therapy is based upon the firm understanding of the anatomical, physiological and pathological processes involved in any specific disease entity. Each contribution must necessarily be only the addition of a brick, or at best a keystone, to the vast masonry work of scientific knowledge. [...]
