PURPOSE Retrospective evaluation of treatment of epiphora due to punctal stenosis with application of perforated plugs as well as evaluation of complications. MATERIAL AND METHOD There were inserted perforated plugs into inferior lacrimal puncta to twelve patients with epiphora due to proximal stenosis in efferent lacrimal ducts. Their size were predeterminated by caliper measuring. Patients ...
The transport of liquid plugs in a microfluidic branching tree is studied experimentally. The global flow pattern can be either symmetric or asymmetric, with daughter plugs dividing in synchrony or asynchrony as a function of the driving flow rate and the network geometry. For trees with narrowing channels, the plugs always reach the exits even at low flow rates. In contrast, only one path is o...
Articular cartilage is avascular. Nutrients are transported to the cells mainly by diffusion from the synovial fluid. Nutrient transport is also sometimes thought to be assisted by movement of fluid in and out of cartilage in response to cyclic loading of the tissue ('pumping'). The influence of pumping on transport of solutes through cartilage was measured by subjecting plugs of human femoral ...
Numerous designs of punctal and canalicular plugs are available on the market. This variety presents challenges to ophthalmologists when choosing punctal plugs for the management of various ocular conditions. The aim of this literature review is to provide a classification system for lacrimal occlusive devices based on their location and duration of action as well as to identify different chara...
A case of a patient who developed multiple calcium oxalate dihydrate calculi, some of them connected to intratubular calcifications (Randall's plugs), is presented. Randall's plugs were isolated and studied. The mechanism of Randall's plug development is also suggested.
One apparent pitfall of the technique was the fact that reactions were carried out first on the plate supernatants and then on individual plugs from the plates, suggesting the possibility of a general contamination of the plugs. We could see that it was not the case and that the contamination level was very low compared with the signal obtained with positive plugs. Therefore, this technique mak...
A 54-year-old woman was admitted for cough, sputum, and an abnormal chest X-ray shadow. Bronchoscopy showed mucoid impaction of the bronchi (MIB). Histopathologic evidence of mucous plugs was consistent with one component of allergic bronchopulmonary mycosis. Schizophyllum commune (S. commune) was identified. Two attempts at removal of the mucous plugs were unsuccessful. Itraconazole was then a...
