BACKGROUND A biofilm is defined as a collection of organisms attached to a surface and surrounded by a matrix. OBJECTIVE To present three cases in which bowel necrosis coexisted with biofilm. METHODS The medical records, bacteriological findings and tissue biopsies from three infants with bowel necrosis who subsequently died from sepsis were analysed. Tissue sent for histological evaluation...

The gold standard treatment of large segmental bone defects is autologous bone transfer, which suffers from low availability and additional morbidity. Tissue engineered bone able to engraft orthotopically and a suitable animal model for pre-clinical testing are direly needed. This study aimed to evaluate engraftment of tissue-engineered bone with different prevascularization strategies in a nov...

At birth, an otherwise healthy term female infant was noted to have a 3 cm blue-coloured tense cyst-like lesion attached by a skin-coloured pedicle to the ulnar aspect of the right hand, adjacent to the fifth metacarpal–phalangeal joint (figure 1). Over the following 48 h, the cystic lesion involuted and appeared necrotic, but remained attached to the hand via a skin-coloured pedicle (figure 2)...

OBJECTIVE To investigate the morphological and structural changes of oral mucosa under the influence of alcohol. METHODS Sixty male and female specimens (42 males and 18 females) who died of chronic alcoholism were selected in this study. The specimens (5-7 mm) were sliced by the morphological-histological detection method, and stained by the HE and Spielmeyer (myelin staining) protocols resp...

The aim of this paper was to develop a computer assisted tissue classification (granulation, necrotic, and slough) scheme for chronic wound (CW) evaluation using medical image processing and statistical machine learning techniques. The red-green-blue (RGB) wound images grabbed by normal digital camera were first transformed into HSI (hue, saturation, and intensity) color space and subsequently ...

Pennyroyal (Mentha pulegium) leaves with small irregular or ellipsoidal necrotic spots were collected in a suburb area of Ardal city, Chaharmahal and Bakhtiari province Iran summer 2018. A fungal isolate was recovered from diseased tissue identified as Bipolaris sorokiniana based on morphological characteristics partial sequence the gpdh gene. In pathogenicity study, disease symptoms observed i...

Rupture of a vulnerable plaque and subsequent thrombus formation are important mechanisms leading to the development of an acute myocardial infarction (AMI). Typical intravascular ultrasound (IVUS) features of AMI include plaque rupture, thrombus, positive remodeling, attenuated plaque, spotty calcification, and thin-cap fibroatheroma. No-reflow phenomenon was attributable to the embolization o...

The gold standard for determining carotid artery stenosis is to calculate using the North American Symptomatic Carotid Endarterectomy Trial criteria and ultimately plan medical vs surgical management based on percent symptomatic status. Few studies have assessed plaque morphology as an additive tool stroke prediction. Our study uses artificial intelligence software in conjunction with a patient...

The goal of root canal treatment is to prevent and treat apical periodontitis, by eliminating inflamed pulp tissue as well microorganism necrotic chemomechanical debridement providing a good quality filling. According Sjögren, et al. [1] the success rate goes high 96% in teeth without periapical lesions. Salehrabi, Rotstein [2] metanalyses, found 97% retention treated while Hannahan, Eleazer [3...
