Bacteriophage types and antibiotic susceptibility of Staphylococcus aureus.

In vitro tests of 132 strains of Staphylococcus aureus, among which were 38 (28.7%) heteroresistant strains, were performed with 14 commonly used antibiotics, including gentamicin and vancomycin. Heteroresistant strains were found predominantly, but not only, with group 3 phage-typable strains; no heteroresistant strain was found in out-patients. Gentamicin appeared as a uniformly effective agent at low concentrations against oxacillin-sensitive and -resistant strains. It is suggested that gentamicin should be compared to vancomycin in future clinical therapeutic trials in severe staphylococcal infections, especially in cases due to oxacillin-resistant strains.

Radiation therapy of the oral cavity: sequelae and management, part 1.

This is the first article in a two-part series dealing with the effects and manifestations in the oral cavity of radiation therapy of head and neck tumors. In this section, oral mucous membranes, taste buds, edema and trismus, diet, salivary glands, bone, periodontium, teeth, and composition of oral flora are discussed. Dental management of the dentulous patient is then approached; criteria for preradiation extraction are delineated. In the next issue of Head & Neck Surgery, the final article in this series will discuss preradiation and postradiation extractions and will elaborate on the dental management (fluoride treatments, follow-up, and restorative care) of the dentulous patient. Dental management of the edentulous patient will also be presented.

Radiation therapy of the oral cavity: sequelae and management, part 2.

This is the concluding portion of a two-part series dealing with the effects and manifestations in the oral cavity of radiation therapy of head and neck tumors. Preradiation and postradiation extractions in dentulous patients, as well as dental maintenance of such patients (including fluoride treatments follow-up, and restorative care), are discussed. Guidelines for the dental management of edentulous patients are also presented at length (this section covers risk of bone necrosis, soft liners, timing of denture placement, dentures and preexisting bone necrosis, soft-tissue necrosis and dentures, morbidity, and prosthodontic procedures). The article concludes with a brief discussion of osteoradionecrosis and soft-tissue necrosis.

A smoking cessation intervention for head and neck cancer patients: trial design, patient accrual, and characteristics.

This paper describes the aims, study design, and patient accrual and characteristics from an ongoing randomized controlled trial evaluating a surgeon- and dentist-delivered smoking cessation intervention for head and neck cancer patients. Subjects (n = 186) accrued into the trial are profiled in terms of demographics, medical and treatment descriptors, smoking history and behavior at enrollment, and related psychosocial variables (mood, adherence indicators, and alcohol consumption). These patients have long histories of tobacco use, moderate to high levels of nicotine dependence, and a lack of overt mood disturbance and are receptive to behavioral change.
