[EX Q]: Abstract: Boerhaave's syndrome represents a diagnostic dilemma for the emergency physician. The prognosis of this truly life-threatening emergency is darkened by any significant diagnostic delay. Unfortunately, classic or expected symptoms and signs are frequently absent at presentation, a circumstance that leads to frequent misdiagnosis. Two cases of Boerhaave's syndrome with "atypical" clinical presentations are reviewed and discussed. It is clear that Boerhaave's syndrome should always be suspected in the evaluation of any sudden chest, abdominal, or back pain associated with emesis. However, emphasis should be placed on the fact that this entity may occur without emesis. The chest radiograph is the most helpful diagnostic aid. Undoubtedly, maintenance of a high degree of suspicion by the emergency physician for Boerhaave's syndrome will lead consistently to earlier diagnosis, and subsequent aggressive intervention should result in considerable reduction in rates of both morbidity and mortality.

[EX Q]: Abstract: Early mobilisation after arthroplasty of the knee sometimes results in wound breakdown. The two commonly used incisions, the anterior midline and the medial parapatellar incisions, were compared in order to determine which had the best potential for wound healing. Study of the cleavage lines around the knee demonstrated that the medial parapatellar incision lies parallel to the lines, whilst the anterior midline incision lies perpendicular to them. In addition, the medial parapatellar wound was found to be subjected to significantly less tension during flexion; after arthroplasty it can be expected to heal faster and to be less liable to disruption during early mobilisation.

[EX Q]: Abstract: A retrospective study of patients patch tested between 1968 and 1970 was undertaken and case records of 200 patients with unequivocal positive patch tests were studied for age and sex distribution. There was an overall female preponderance (61%), with 2 peaks of incidence in the 10-20 and 40-50 year age groups in females, but only 1 peak of incidence in the 40-50 year age group in males. There was a steady decline in all sensitivities after the 6th decade of life in both sexes. Nickel sensitivity was more common in females (92%), whereas dichromate sensitivity predominated in males (64%). Of the 200 patients, only 5(2.5%) were atopics, all of whom were females.
