Lid lesions of childhood: a histopathologic survey at the Wilmer Institute (1923-1974).

This study reports 398 excised eyelid lesions in 385 children from birth through age 15. This study analyzes and discusses the clinical and histological features of the 34 types of lesions which were encountered. This tabulation serves as a guide to the physician when confronted with lid lesions in children as to the types of lesions which may be found. More importantly, however, this study is the first comprehensive clinco-pathologic evaluation of eyelid lesions in children, a topic which had previously been written and discussed in a fragmentary manner. This study analyzes data from the Wilmer Institute during 1923-1974.

Experimental production of cartilage necrosis by cold injury: failure to cause degenerative joint disease.

A cryoprobe (-20 to -80 C) was applied for 10-60 seconds to cause necrosis of metatarsal head cartilages of 11 rabbits. Segmental loss of nuclear staining was noted at 1 week and depletion of chondroitin sulfate (toluidine blue metachromasia and staining with safranin 0) a few days later. No degenerative joint disease was evident up to 6 months later. The latter finding suggests that, in addition to chondrocyte death, externally imposed stresses are necessary to disrupt the collagenous "skeleton" and initiate the changes of degenerative joint disease.

Primary vitrectomy for rhegmatogenous retinal detachment: an analysis of failure.

PURPOSE: To find the cause of failure in primary vitrectomy for rhegmatogenous retinal detachment. METHODS: Retrospective review of 171 consecutive cases of RRD treated by primary pars plana vitrectomy (PPV) from a tertiary referral centre to identify the 25 cases in which surgery had failed. Detachments with giant or macula breaks at initial presentation, with proliferative diabetic retinopathy or with PVR greater than grade B were excluded. RESULTS: The failure rate after the first operation was 14.6% and the commonest cause of failure was missed retinal breaks, accounting for 64.3% of failures. CONCLUSION: Missed retinal breaks are the commonest cause of failure of primary PPV for RRD although proliferative vitreoretinopathy may contribute to surgical failure. This re-emphasises the importance of assiduous peroperative retinal examination.

Volkmann's ischemia. A volar compartment syndrome of the forearm.

In a series of 19 patients with Volkmann's iscemia, 63 per cent had suffered skeletal trauma, whereas 38 per cent had received non-skeletal trauma. Non-specific trauma may trigger an ischemia-edema cycle, producing increased intracompartmental pressure. This cycle, if unrelieved, can involve all of the muscles in the compartment, via cyclic propagation and reinforcement of arterial spasm. The volar compartmental syndrome is not an all or none phenomenon. Localized ischemia may trigger a gradually spreading arterial spasm which results in slowly progressive clinical changes as late as 3-4 months after onset. Decompression not only of the compartment but of each individual muscle which shows evidence of vascular compromise, may reverse this destructive cycle even as late as 3-4 months but it should be performed promptly with the onset of symptoms, when its effect is rapid and dramatic. Induration of the compartment is pathognomonic of the compartmental syndrome. As long as it is present, benefit can be expected from decompression procedures. Regeneration of necrotic ischemic muscle is possible following restoration of circulation.
