Burkholderia is an important bacterial genus with a complex taxonomy that contains species of both ecological and pathogenic importance, including nine closely related species collectively termed the Burkholderia cepacia complex (BCC). In order to more thoroughly investigate the virulence of this bacterial complex of microorganisms, alternative infection models would be useful. To this end, we ...

A nosocomial polyclonal outbreak associated to bacteremia caused by different Burkholderia cepacia complex (BCC) species and clones is reported. Molecular characterization identified Burkholderia stabilis, Burkholderia contaminans, and Burkholderia ambifaria among BCC isolates obtained from patients in neonatal and adult intensive care units. BCC was also isolated from an intrinsically contamin...

Giant basal cell carcinoma (BCC), defined as a lesion greater than 5 cm at its largest diameter, is a rare variant of BCC. In contrast to small BCC, giant BCC develops on skin that is not exposed to sunlight, including the back, shoulder, groin and thigh. Most of the histopathologic subtypes of giant BCC are micronodular, morpheaform and nodular, but the superficial subtype is rare. Giant super...

Burkholderia cepacia complex (Bcc) bacteria reside in soil, plant rhizospheres, and water, but their prevalence and distribution in outdoor environments is not clear. We sampled a variety of soil and rhizosphere environments with which people may have contact: playgrounds, athletic fields, parks, hiking trails, residential yards, and gardens. A total of 91 sites was sampled in three large U.S. ...

Basal cell carcinoma (basalioma, BCC) is the most common skin cancer and the most common human malignancy in general, with a continuously increasing incidence. In most cases, BCC develops on chronically sun-exposed skin in elderly people, most commonly in the head and neck region. Besides chronic UV radiation, other risk factors for the development of BCC include sun bed use, family history of ...

Basal cell carcinoma (BCC) is the most common skin cancer. The most significant risk factor is ultraviolet radiation and the most frequent site of BCC is head and neck, with around 75-80% occurring on face. BCC occurs infrequently in non-sun-exposed skin. The axilla is one of the least sun-exposed areas of our body, and as such BCC at this site is very rare. We present a case of large neglected...

Basal cell carcinoma (BCC) is the most frequent malignant skin tumor, which is associated with both genetic factors and environmental influences. The objective of this study was to investigate the risk factors associated with the occurrence of BCC in the inhabitants of the Western Herzegovina area. The study took place during 1997-2003. We examined the risk factors which are presumably associat...

BACKGROUND In vivo reflectance confocal microscopy (RCM) is a promising non-invasive skin imaging technique that could facilitate early diagnosis of basal cell carcinoma (BCC) instead of routine punch biopsies. However, the clinical value and utility of RCM vs. a punch biopsy in diagnosing and subtyping BCC is unknown. OBJECTIVE To assess diagnostic accuracy of RCM vs. punch biopsy for diagno...

We address crystal nucleation and fcc-bcc phase selection in alloys using a multiphase field model that relies on Ginzburg-Landau free energies of the liquid-fcc, liquid-bcc, and fcc-bcc subsystems, and determine the properties of the nuclei as a function of composition, temperature, and structure. With a realistic choice for the free energy of the fcc-bcc interface, the model predicts well the...
