BACKGROUND To report a case of interface fluid syndrome (IFS) following small incision lenticule extraction (SMILE) evaluated with corneal densitometry and optical coherence tomography (OCT). CASE PRESENTATION An 18-year-old man reported sudden vision loss 24 days after SMILE procedure. Intraocular pressure (IOP) was 36.3 mmHg (OD) and 36.7 mmHg (OS) by noncontact tonometry. Moderate corneal ...

Concern for bone fragility in children and adolescents has led to increased interest in bone densitometry. Pediatric patients with genetic and acquired chronic diseases, immobility, and inadequate nutrition may fail to achieve the expected gains in bone size, mass, and strength, which leaves them vulnerable to fracture. In older adults, bone densitometry has been shown to predict fracture risk ...

PURPOSE To evaluate the changes in corneal transparency and thickness measured objectively using Pentacam Scheimpflug (Oculus Optikgeräte GmbH) corneal tomography (densitometry) after corneal cross-linking (CXL). METHODS Twenty-two eyes from 15 patients with keratoconus underwent CXL. Corneal thickness and curvature as well as lens and corneal densitometry were measured at baseline and 1, 3, ...

background: nontypeable haemophilus influenzae (nthi) is a common cause of respiratory tract disease and initiates infection by colonization in nasopharynx. the haemophilus influenzae (h. influenzae) hap adhesin is an auto transporter protein that promotes initial interaction with human epithelial cells. hap protein contains a 110 kda internal passenger domain called “haps” and a 45 kda c-termi...

Standardization of toxin preparations derived from Bacillus thuringiensis (Berliner) used in laboratory bioassays is critical for accurately assessing possible changes in the susceptibility of field populations of target pests. Different methods were evaluated to quantify Cry1Ab, the toxin expressed by 80% of the commercially available transgenic maize that targets the European corn borer, Ostr...

PURPOSE To determine the natural history of collagen crosslinking (CXL)-associated corneal haze measured by Scheimpflug imagery and slitlamp biomicroscopy in patients with keratoconus or ectasia after laser in situ keratomileusis. SETTING Cornea and refractive surgery subpecialty practice, United States. DESIGN Prospective randomized controlled clinical trial. METHODS The treatment group ...

introduction: this study was conducted to evaluate prevalence and risk factors for diagnostic discordance for osteoporosis due to different t-scores of lumbar spine and femoral neck. methods: in this cross sectional study demographic, anthropometric and risk factors for osteoporosis were derived from a database on 3,039 post-menopausal women who underwent bone densitometry for the first time i...
