Recently, numerous publications have appeared warning that oil production is near an unavoidable , geologically-determined peak that could have consequences up to and including ªwar, starvation, economic recession, possibly even the extinction of homo sapiensº (Campbell in Ruppert 2002) The current series of alarmist articles could be said to be merely(More)
BACKGROUND Studies have shown that the nature and amount of supragingival plaque can influence the composition of the contiguous subgingival flora. The purpose of this study was to investigate the effect of rinsing with an essential oil antimicrobial mouthrinse on levels of representative subgingival bacteria in subjects with mild to moderate periodontitis.(More)
AIM This study was conducted to investigate the effect of rinsing with an essential oil-containing mouthrinse on levels of specific supra and subgingival bacteria in subjects with gingivitis. MATERIAL AND METHODS Fifteen subjects meeting entry criteria completed this randomized, controlled, double-blind, crossover study. Subjects were required to have(More)
BACKGROUND The purpose of this study is to investigate the antimicrobial effects of minocycline hydrochloride microspheres versus infrared light at 810 nm from a diode laser on multispecies oral biofilms in vitro. These biofilms were grown from dental plaque inoculum (oral microcosms) and were obtained from six systemically healthy individuals with(More)
Tick bites can cause a number of local inflammatory reactions, which are often difficult to differentiate from those induced by other arthropod bites or stings. These include erythematous nodular or pustular lesions, erosive plaques, annular lesions of erythema chronicum migrans, and both scarring and nonscarring inflammatory alopecia. We report a case of(More)
Epithelioid sarcoma (ES) is a rare malignancy notorious for its tendency to histologically mimic granuloma annulare and other palisading granulomatous processes. We report a case of ES on the right hand of a 23-year-old man that histopathologically resembled a benign fibrous histiocytoma. Superficial portions of the tumor were well differentiated,(More)
Extraskeletal Ewing's sarcoma (EES), or primitive neuroectodermal tumor, is an uncommon neoplasm with low incidence in the head and neck. Occurrences in the larynx are even more exceptional with only two previous reported cases of EES arising from the larynx. We report the case of a 45-year-old woman with a laryngeal Ewing's sarcoma treated with(More)
A teenage girl presented with multiple warty skin lesions and had a diagnosis of epidermodysplasia verruciformis made several years later. Later in life she presented with an extensive SCC in situ in her gluteal crease that was surgically resected with wide margins. Despite this treatment, the lesion recurred with extension onto her lower back. Biopsies at(More)
AIM This 4-week, single-centre, randomized, examiner-blind, controlled study investigated the efficacy and safety of 0.15% ethyl lauroyl arginate (LAE)-containing mouthrinse in adults with mild-to-moderate gingivitis. MATERIAL AND METHODS Subjects were randomized to use 0.15% LAE-containing mouthrinse or 5% hydroalcohol-negative control twice daily after(More)
