Carcinomas of the lacrimal drainage system
Head & Neck, 1993AbstractPrimary carcinomas of the lacrimal drainage system are rare. These malignant neoplasms typically present as noncompressible, nontender masses with low‐grade dacyrocystitis and/or unilateral epiphora. Lymph node metastasis may occur late in the disease course. Complete surgical resection is the best treatment choice; extensive procedures such as

Obstruction of the lacrimal drainage system
Current Opinion in Ophthalmology, 2002This review covers evolving concepts in lacrimal outflow obstruction. Recent studies have increased our understanding of the surgical anatomy and pathophysiology of the lacrimal drainage system through radiologic, clinical, and microbiologic techniques.

Lacrimal Drainage System Obstruction
Seminars in Ophthalmology, 2010The lacrimal drainage system consists of the lacrimal puncta, inferior and superior canaliculi, common canaliculus, lacrimal sac, and nasolacrimal duct. It is classically divided into upper and lower portions. Obstruction of the drainage system can be congenital or acquired, and may result in persistent epiphora and mucopurulent discharge.

Tumors of the Lacrimal Drainage System
Orbit, 2010Tumors of the lacrimal drainage system are rare, but potentially life-threatening. They comprise a large and variable spectrum of entities grouped into three major categories of primary epithelial, primary nonepithelial and inflammatory lesions. The most common primary epithelial tumors include papilloma, squamous cell carcinoma and transitional cell ...

Detergents in drainage systems for buildings
Water Research, 2001Current soil waste vent (SWV) system design guides aim to produce ventilated drainage networks for buildings which protect attached water trap seals from unwanted air pressure effects. Such effects may cause trap seal failure that are caused by airflow induction during discharge.

An improved system of bladder drainage
Australian and New Zealand Journal of Obstetrics and Gynaecology, 2001Summary: We report the successful use of a modified No. 8 infant feeding tube for postoperative bladder drainage in 100 gynaecological patients after surgery.In previous years, problems arising from the use of transurethral postoperative catheter drainage led to the use of various types of suprapubic catheter drainage after gynaecological surgery ...

Evaluation of the Lacrimal Drainage System
Ophthalmology, 1978Methods of testing for lacrimal drainage insufficiency and a modification of the Jones fluorescein dye tests are presented. Despite their excellence, Jones tests have never been widely employed because of difficulty in dye retrieval. The modification consists of instilling one drop of the dye three times at 15 second intervals, and after a one minute ...

A Model for Fluid Drainage by the Lymphatic System
Bulletin of Mathematical Biology, 2012This study investigates the fluid flow through tissues where lymphatic drainage occurs. Lymphatic drainage requires the use of two valve systems, primary and secondary. Primary valves are located in the initial lymphatics. Overlapping endothelial cells around the circumferential lining of lymphatic capillaries are presumed to act as a unidirectional ...

Der Unfallchirurg, 1996
A study of 120 total hip replacements showed the advantages of the variable vacuum drainage system over the continuous high vacuum drainage system. Better wound healing, less severe hematomas and less occlusion of drains confirmed the higher effectiveness of secretion draining.

Drainage Systems for Condensation
Journal of Engineering for Power, 1974Efficient condensing surfaces are highly desirable in the design of solar sea power plants utilizing the ocean temperature difference. This paper examines a number of surface designs and presents a convenient method for optimizing the design. In particular, the various parameters of a Gregorig surface are optimized.
