Femtosecond laser versus mechanical microkeratome laser in situ keratomileusis for myopia: Metaanalysis of randomized controlled trials.

2011

Purpose To examine differences in efficacy, accuracy, safety, and changes in aberrations between femtosecond and mechanical microkeratome laser in situ keratomileusis (LASIK) for myopia. Setting Department of Ophthalmology, Shanghai First People's Hospital Affiliated to Shanghai Jiaotong University, Shanghai, China. Design Evidence-based manuscript. Methods Data sources, including PubMed, Medline, EMBASE, and Cochrane Controlled Trials Register, were searched to identify potentially relevant prospective randomized controlled trials. Primary outcome measures were efficacy (uncorrected distance visual acuity ≥20/20), accuracy (±0.50 diopter mean spherical equivalent), and safety (loss of ≥2 l…

Effects of LASIK on Corneal Endothelium Using the 15-kHz IntraLase Femtosecond Laser

2011

PURPOSE: To assess the effects of LASIK with the 15-kHz IntraLase femtosecond laser on corneal endothelium. METHODS: In a prospective, single-center clinical trial, 138 patients (mean age: 32.0±7.1 years [range: 21 to 42 years]) underwent femtosecond LASIK for the correction of myopia −0.75 to −9.00 diopters (D) and cylinder up to 3.25 D. Patients were divided into two groups: contact lens group (n=76) and non-contact lens group (n=62). Pre- and 12-month postoperative specular microscopy of the central corneal endothelium was performed. The integrity of the central endothelium was assessed in terms of endothelial cell density and percentage of hexagonality. RESULTS: In the contact lens gro…

Femtosecond laser versus mechanical keratome LASIK for myopia.

2005

To assess efficacy, safety, predictability, stability, and changes in corneal higher-order aberrations (CHOAs) and contrast sensitivity (CS) after a femtosecond laser for LASIK and standard LASIK for myopia.Prospective, randomized, comparative clinical study.Two hundred eyes of 100 consecutive patients who underwent LASIK treatment using the VISX S2 laser system. A femtosecond laser for flap creation was used in 100 eyes (50 patients; spherical equivalent [SE], -2.85+/-1.79 diopters [D]), and a mechanical microkeratome was used in 100 eyes (50 patients; SE, -2.90+/-1.63 D).Uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), manifest refraction, CS by means of t…

Contrast sensitivity after LASIK flap creation with a femtosecond laser and a mechanical microkeratome

2007

ABSTRACT PURPOSE: To compare the effects on contrast sensitivity of the IntraLase femtosecond laser for flap creation (IntraLASIK) and standard LASIK for myopia. METHODS: Two hundred eyes of 100 consecutive patients underwent LASIK treatment using the VISX S2 laser system. The femtosecond laser (15 kHz IntraLase) was used for flap creation in 100 eyes (50 patients) and a mechanical microkeratome (Carriazo-Barraquer) was used in 100 eyes (50 patients). Best spectacle-corrected contrast sensitivity was measured before and 6 months postoperatively in the IntraLASIK and mechanical LASIK groups. The IntraLASIK and mechanical LASIKinduced changes in contrast sensitivity were compared under photop…

Data from: Moving in the Anthropocene: global reductions in terrestrial mammalian movements

2019

Animal movement is fundamental for ecosystem functioning and species survival, yet the effects of the anthropogenic footprint on animal movements have not been estimated across species. Using a unique GPS-tracking database of 803 individuals across 57 species, we found that movements of mammals in areas with a comparatively high human footprint were on average one-half to one-third the extent of their movements in areas with a low human footprint. We attribute this reduction to behavioral changes of individual animals and to the exclusion of species with long-range movements from areas with higher human impact. Global loss of vagility alters a key ecological trait of animals that affects no…

First record of Beroe gracilis Künne, 1939 (Ctenophora: Beroida: Beroidae) from Norway, found in a Mnemiopsis leidyi A. Agassiz, 1865 bloom

2015

In September 2014 an unusual mixture of ctenophores was recorded at Arboretet, south-western Norway and at Flødevigen, near Arendal on the south coast of Norway. In addition to the invasive American lobate ctenophore,Mnemiopsis leidyi, the common northern lobate ctenophoreBolinopsis infundibulumand the cydippidPleurobrachia pileus, two beroid ctenophores, were noted –Beroe cucumisandBeroegracilis. The latter species had not been documented before in Norwegian waters.

ILEO BILIARE: DIAGNOSI E TRATTAMENTO. CASE REPORT

2006

The authors present a case of gallstone intermittent ileus caused by the passage of a big gallstone (about 4 cm in diameter) in the intestinal lumen, through a cholecystoduodenal fistula. They emphasize the peculiarity of the case for the characteristics of symptoms and for casual diagnostic check-up with a ultrasonography. The disease is not frequently diagnosed; today it has a safe recognition by modern imaging. The symptoms can be intermittent and, even when there are the classic signs of intestinal occlusion, the site of the occlusion is various. With a timely endoscopical or surgical approach (open or laparoscopic) it is possible to reduce mortality of patients treated in emergency.

Contrasting the Effects of Maternal and Behavioral Characteristics on Fawn Birth Mass in White-Tailed Deer

2015

Maternal care influences offspring quality and can improve a mother’s inclusive fitness. However, improved fitness may only occur when offspring quality (i.e., offspring birth mass) persists throughout life and enhances survival and/or reproductive success. Although maternal body mass, age, and social rank have been shown to influence offspring birth mass, the inter-dependence among these variables makes identifying causation problematic. We established that fawn birth mass was related to adult body mass for captive male and female white-tailed deer (Odocoileus virginianus), thus maternal care should improve offspring fitness. We then used path analysis to identify which maternal characteri…

Post-operative ileus in elderly patients

2009

Materials and methods Data collected from 20 patients undergoing right hemicolectomy for right bowel cancer were evaluated. Patients included were divided in two groups of 10 subjects respectively, according their age. In the first group were allocated patients of age ≥ 70 years, whereas in the second group were included subjects of age ≤ 60 years. Patients affected by postoperative delirium or presenting complications that could altered the regain of intestinal motility were excluded. The time of first passage of flatus, the time of first defecation and the postoperative stay were evaluated.
