This study aimed to evaluate the role of gender in types and frequency of coronary artery aneurysm and ectasia.We assessed retrospectively the angiography records of 6100 patients. At first, we mainly reviewed angiographic movies for the presence of coronary ectasia and/or aneurysm. Consequently, based on the number of the coronary artery involvement, the coronary ectasia and aneurysm were grad...

PURPOSE To analyze the risk factors associated with a series of ectasia cases following photorefractive keratectomy (PRK) and all published cases. METHODS In a retrospective study on post-PRK ectasia patients, 9 eyes of 7 patients were included, in addition to 20 eyes of 13 patients from the literature. Risk of post-PRK ectasia was calculated using the ectasia risk score system (ERSS) for las...

PURPOSE To present the Tomographic and Biomechanical Index (TBI), which combines Scheimpflugbased corneal tomography and biomechanics for enhancing ectasia detection. METHODS Patients from different continents were retrospectively studied. The normal group included 1 eye randomly selected from 480 patients with normal corneas and the keratoconus group included 1 eye randomly selected from 204...

Chernogubov-Ehlers-Danlos and Marfan syndromes are among the most prevalent disorders of connective tissue, health care providers various specialties may deal with such patients. The agreed diagnostic criteria have been devised for these diseases they should be used conducting a thorough medical examination. article refers to some difficulties associated application clinical practice. As result...

Corneal ectasia is a serious complication of laser in situ keratomileusis (LASIK). We report the case of a 29-year-old man who underwent LASIK in both eyes and in whom corneal ectasia developed in the left eye 3 years after surgery. He was treated sequentially with intraocular pressure-lowering medication, intrastromal corneal ring segment (ICRS) implants, and collagen cross-linking. Vision imp...

The incidence of male duct ectasia (periductal mastitis) is extremely rare, only eight cases having been reported. The underlying cause (as in females) is uncertain. Two cases in HIV positive males of recurrent unilateral nipple lesions are reported with histology consistent with duct ectasia. At presentation neither patient had an AIDS defining illness. An impaired immunity secondary to HIV in...

frequent cause of lower intestinal bleed− ing in the elderly. Recent advances in co− lonoscopy have discovered colonic vascu− lar ectasia with increasing frequency. Co− lonic vascular ectasia often presents as multiple reddish, slightly elevated, muco− sal lesions. It may be treated at colonos− copy with laser photocoagulation, heat probe, electrocoagulation, and argon plasma coagulation [1 ± 4...

1 for their comments on our recent review of dural arteriovenous fistula (DAVF). 2 We disagree with their suggestion that meningeal vessels exclusively supply DAVFs. Although pial supply is rare, we have observed it on several occasions, and it has been described in the literature. 3 We recognize the contributions made by Houser et al and Djindjian in the identification of cortical venous drain...

collagen fibrils, extracellular empty spaces(likelyclefts formedfromlipid removalduringprocessing), andpersistentlyactivatedkeratocytesaresimilar to these animal findings. The extracellular lipid collections, which likelycorrespondtothecrystallinedeposits seen clinically, probably arise fromchronicmechanical irritation to keratocytes that continually strive to heal the stromal wound. The breaks...
