purpose : to determine the efficacy of fibrin glue in corneal perforations up to 3 mm in diameter methods : a case series study was performed on corneal perforations up to 3 mm who were admitted at farabi hospital- tehran. age, visual acuity, presence and size of corneal thinning, corneal epithelial defect, size and depth of corneal infiltration, site and size of corneal perforation, corneal va...

This paper presents a modified analytical formula for estimating the static top-to-bottom compressive strength of corrugated board packaging with different perforations. The framework is based here on Heimerl’s assumption an extension from single panel to full box, enhanced numerically calculated critical load. In proposed method, torsional and shear stiffness cardboard, as well depth-to-width ...

Acoustic impedance of perforations in contact with fibrous material, as well as air alone, is experimentally determined in the absence of mean flow. Different porosities 2.1, 8.4, 13.6, and 25.2 % and hole diameters 0.249 and 0.498 cm are applied for perforations, along with two fiber filling densities 100 and 200 kg/m3 to illustrate the effect of variations in such parameters on the perforatio...

OBJECTIVES The clinical features of various facial deformities in Korean leprosy patients were evaluated according to the type of leprosy. METHODS One hundred ninety six patients with leprosy were examined for various facial deformities using a nasal speculum, endoscope, and digital camera. The frequency and severity of external nasal deformities and septal perforations were evaluated accordi...

BACKGROUND AND PURPOSE The risk of intraprocedural aneurysm perforation in patients with previously ruptured aneurysms tends to be higher than that of patients with previously unruptured aneurysms, but a statistically significant difference has not been shown. Our purpose was to define the rates of occurrence and of morbidity and mortality associated with aneurysmal perforation associated with ...

Finney (I900) stated that in 20 per cent. of patients with a perforated peptic ulcer, more than one perforation occurred. Fifty years later Aird gives a figure of less than I per cent.; both report multiple perforations of a single large ulcer. Yet, while every volume of the 'Index Medicus' contains hundreds of references to peptic ulceration, reports of double perforations are rare. Masson and...

This prospective study was conducted to evaluate the efficacy of sea buckthorn oil patches in treating traumatic tympanic membrane (TM) perforations. We enrolled 370 patients with traumatic TM perforations of different sizes. These patients were randomly assigned to control group and treatment group. In the treatment group, a sterile cotton patch with sea buckthorn oil was used to cover the TM ...

OBJECTIVE To compare the efficacy of three different myringoplasty techniques, namely hyaluronic acid fat graft myringoplasty (HAFGM), fat graft myringoplasty (FGM), and temporal fascia for the closure of different sizes and sites of tympanic membrane perforations. MATERIALS AND METHODS We retrospectively analyzed the medical records of patients who had undergone a type 1 tympanoplasty operat...

Implant placement in the posterior maxilla often requires elevation of the sinus floor, which can be achieved through either the modified Caldwell-Luc or the crestal osteotome technique. The objectives of this study were to evaluate (a) the resistance to perforation of maxillary sinus membranes obtained from formaldehyde-fixed cadavers in vitro, (b) the frequency and extent of membrane perforat...
