An amorphic lens, designed by William Feinbloom, was tested on 69 patients with retinitis pigmentosa. The results showed that one-half of the patients experienced immediate improvement in mobility and one-third of the patients fitted with the amorphic lens reported (after wearing the lenses for 2 weeks) improved mobility compared to their mobility before using the lens.
From 1970 to 1984 late complications including the prox. anastomosis of aortoiliacal/-femoral bifurcation-prothesis were observed angiographically in 37/647 (6.5%) of patients with art. occl. disease and 4/367 (1.1%) of patients with aneurysmatic disease. Concerning the dist. bilateral anastomotic region the complication-rate was markedly higher. This study was carried out to evaluate accuracy of transvenous DSA in a preselected outpatient group (n = 24) following aortoiliacal/-femoral bifurcation-bypass. In 15 cases DSA showed prothetic complications such as occlusion (n = 4), stenosis (n = 2), anastomotic aneurysms (n = 8) and a.v. fistula (n = 1). The results demonstrate that in outpatients transvenous DSA is a method of low risk to get excellent images of bifurcation-prothesis and prothetic complications considering recommended technical criteria.

Cell behavior is three-dimensional (3-D), even when it takes place on a flat surface. Migrating cells form pseudopods on and off the substratum, and the cell body undergoes height changes associated with a 1 min behavior cycle. Inside the cell, the nucleus has a 3-D migratory cycle, and vesicles move up and down in the z-axis as a cell locomotes. For these reasons, the two-dimensional (2-D) analysis of cellular and subcellular behavior is, in many cases, inadequate. We have, therefore, developed 3-D motion analysis systems that reconstruct the cell surface, nucleus, pseudopods, and vesicles of living, crawling cells in 3-D at time intervals as short as 1 s, and compute more than 100 parameters of motility and dynamics morphology at 1-s intervals. We are now in the process of developing a multimode reconstruction system that will allow us to reconstruct and analyze fluorescently tagged molecular complexes within the differential interference contrast-imaged subcellular architecture of a crawling cell. These evolving technologies should find wide application for a host of biomedical problems.
OBJECTIVE: To report the clinical signs and management of 4 foals with persistent frenulum of the epiglottis. STUDY DESIGN: Case report. ANIMALS: Four newborn foals. METHODS: Foals were admitted with a complaint of oronasal reflux after nursing. Variable systemic signs of aspiration pneumonia were evident. Nasal endoscopy confirmed persistent dorsal displacement of the soft palate. Persistent frenulum of the epiglottis, confirmed by oral endoscopic examination, was transected. RESULTS: After surgery, all foals had the epiglottis positioned normally, dorsal to the soft palate. Clinical signs of oronasal reflux resolved by the second nursing attempt in 3 foals, whereas this was difficult to assess in one foal that was nursed intermittently because of the mares behavior. This foal died 2 days later. The other 3 foals have had normal epiglottic function for 2-4 years. CONCLUSIONS: Persistent frenulum of the epiglottis should be considered in foals with oronasal reflux from birth. With appropriate medical and surgical management the prognosis for resolution should be good.
According to the records of the Royal College of Obstetricians and Gynaecologists (1990) more than 80,000 hysterectomies were performed in the UK during 1990. Minimally invasive procedures are replacing conventional hysterectomies in ever-increasing numbers. This article describes the techniques and considers whether the trend is a welcome one.
