Riboflavin/UVA cross-linking is a technique introduced in the past decades for the treatment of keratoconus, keratectasia, and infectious keratitis. Its efficacy and safety have been investigated with clinical and laboratory studies since its first clinical application by Wollensak for the treatment of keratoconus. Although its complications are encountered during clinical practice, such as inf...

introduction for decades, acetabular fractures were treated conservatively. judet et al. in 1960s established the operative treatment of these fractures by continuous improvement of pre-operative evaluation and classification of fractures. several studies demonstrated that accurate fracture reduction decreases the incidence of post-traumatic arthritis and improves functional outcome. conclusion...

a 32-year-old female patient with previous bentall operation and mitral valve repair surgery due to severe aortic insufficiency, mitral valve insufficiency, and ascending aortic aneurysm was admitted to our hospital with serious dyspnea, fatigue, and mild chest pain. two-dimensional echocardiography demonstrated a markedly dilated basal aorta and cardiac chambers. thoracic computed tomography s...

context hepatocellular carcinoma (hcc) is a fatal disease. chronic hepatitis b virus (hbv) and/or hepatitis c virus (hcv) infection is the major cause of hcc. high viral replication rate and related hepatic/systematic inflammation are the major risk factors in hcc recurrence after hepatectomy or liver transplantation. evidence acquisition some of the carcinogenesis-related hbv mutations are als...

introduction: tonsillectomy is the one of the most common types of surgery in children, and is often accompanied by post-operative pain and discomfort. methods of pain control such as use of non-steroidal anti-inflammatory drugs (nsaids), narcotics, and local anesthetics have been used, but each have their own particular side effects. in this study we investigated the effect of ketamine on post...

objective(s)the purpose of this study holds, for the first time, an evaluation of the intraperitoneal curcumin lavage on the development of post-operative intra-abdominal adhesions.materials and methodsthirty male wistar rats were randomized into five groups. the rats were administered anesthesia and underwent surgery in order to create intra-abdominal adhesions. before the abdomen was closed, ...

background & aim: operation as a stressor can induce physical and psychological negative reactions. considering the anxiety prevalence as the most important sign and symptoms before surgery, on one hand, and the necessity of patients’ mental preparation as the most essential care before surgery, on the other hand, the importance of primary communication of medical centers’ staff would be determ...

UNLABELLED Our understanding of etiology and pathogenesis of many disorders, corneal included, greatly relies on existing knowledge in human biochemistry and biophysics. This study was aimed at chemical mapping of normal and keratoconic corneas. MATERIAL AND METHODS Modern methods of analytical chemistry, such as X-ray fluorescence and energy-dispersive X-ray spectroscopy on the basis of scan...

We describe a technique using deep anterior lamellar keratoplasty (DALK) in 5 eyes that developed keratectasia after LASIK. The technique is based on surgical manipulation that allows visualization of the lamellar dissection depth using a posterior approach to reach the predescemetic space. The mirror effect, indentation effect, and folding effect were used to determine proximity to Descemet's ...
