Natural history of Candida species and yeasts in the oral cavities of infants

A longitudinal study was made of the presence of Candida species and yeasts in infants from the day of birth until 1-yr-old, diagnosed by the culture of oral swab samples. The isolation rate of Candida rose from 5.7 per cent neonatally to 14.2 per cent on discharge from hospital at 7 days. The prevalence increased sharply when the infants returned home, reaching 82 per cent at 4 weeks of age, but then slowly declined to 50 per cent at 1 yr. At 4 weeks, yeasts were isolated from an additional 14 per cent of infants. The predominant species was C. albicans with relatively few isolates of C. tropicalis, C. parapsilosis and C. pseudotropicalis. Estimates of neonatal serum antibody to C. albicans showed no correlation with initial or subsequent oral colonization by this organism.     

Digital subtraction arthrography and arthrofluoroscopic dynamic observations on TMJ dysfunction syndrome

Digital subtraction arthrography and arthrofluoroscopic dynamic observation were performed for seventy cases with TMJ dysfunction syndrome. A comparative study between the findings of digital subtraction arthrography and the operative findings was carried out for eleven cases who underwent surgery. It has been found that digital subtraction arthrography can overcome the disadvantages of conventional arthrography and has important diagnostic value for TMJ dysfunction syndrome, especially for disc perforation. In addition. The procedure of digital subtraction arthrography, the normal and abnormal manifestations of digital subtraction arthrograms were described in the present study.
