The slide centrifuge gram stain as a urine screening method.

A slide centrifuge Gram stain procedure was performed to screen for bacteriuria 4161 urine specimens submitted in urine preservative tubes for routine culture. For slide centrifuge Gram staining, each urine sample was mixed well. Thereafter, 0.2 mL of each sample was placed, using a pipette, into a slide centrifuge chamber and centrifuged at 2,000 rpm for 5 minutes. The slides were heat fixed, Gram stained, and read by laboratory personnel who scanned 12 consecutive oil-immersion fields using a set pattern. The presence of the same organism in six or more fields was defined as a positive urine screen. Urine samples were cultured using a 0.001-mL loop and a comparison of culture growth with slide centrifuge screening was made. When growth of 100,000 or more colony-forming units per milliliter (CFU/mL) was the reference for comparison, the screen had a sensitivity rate of 98%, a specificity rate of 90%, a negative predictive value of 99%, and a positive predictive value of 65%. When a lower colony count of 10,000 or more CFU/mL was the reference for comparison, the screen had a sensitivity rate of 88%, a specificity rate of 95%, a negative predictive value of 96%, and a positive predictive value of 84%. The slide centrifuge Gram stain is a very sensitive screening method to detect bacteriuria in an adult male population.

Disability and rehabilitation in head and neck cancer patients after treatment.

In an effort to obtain quantitative and qualitative information regarding the extent of disability sustained following definitive treatment for head and neck cancer, 51 patients--28 who had had laryngectomy and 23 who had had other major surgery--were interviewed. Also examined were the types of rehabilitation measures taken. In all cases, the following areas in which disability could occur were identified and explored: physical appearance, speech, deglutition, mastication, salivation, sensory deficits, cranial motor-nerve deficits, pain, nutrition, activities of daily living, psychosocial functioning, vocational status, environmental parameters, and delayed complications. Where appropriate, ratings and delineations of severity were compiled. Nine methods of rehabilitation were assessed with regard to frequency of utilization: surgical reconstruction, dental-maxillofacial prosthetics, speech therapy, physical therapy, rehabilitation nursing, occupational therapy, vocational rehabilitation, rehabilitation counseling, and social service. Our conclusions were that half of the patients studied had sustained significant disability in three to four areas, while 43% had moderate or severe disability in five to nine areas. Additionally, the head and neck surgeon was found to have used surgical reconstruction and dental-maxillofacial prosthetic measures, as well as the services of seven categories of allied health professionals, to provide rehabilitation.
