The incidence of hospital fungal infections--yeast fungaemia.

In order to determine the incidence and the causative agents of fungaemia, a survey was undertaken of blood culture specimens received from the Bloemfontein academic hospitals. Over a period of 1 year, 5,017 successive blood cultures were examined; 1,030 (20.5%) had growth of which 106 (2.1%) yielded yeasts. Candida albicans (42%), C. tropicalis (26%) and C. parapsilosis (20%) were the species most frequently isolated. Fungaemia occurred most often after broad-spectrum antimicrobial therapy and abdominal disorders.

[Rapid identification methods of yeasts during fungaemia].

A wet preparation method, modified serum test and a modified disc diffusion method were evaluated in order to identify yeasts more rapidly during fungaemia. A total of 2,932 blood cultures were processed, of which 54 (1.8%) yielded yeasts. By using these methods, Candida albicans was identified within 3 hours, after yeast growth in the blood culture was confirmed by Gram stain. The wet preparation examinations were accurate in 60% of cases and the serum test in 95% of cases. After growth was detected, yeast species other than C. albicans were identified within 24 hours using the modified disc diffusion method. C. albicans (50%), C. tropicalis (22%) and C. parapsilosis (22%) were the species most frequently isolated. Fungaemia occurred most often after antimicrobial therapy and abdominal conditions.

Iopamidol for myelography--practical implications.

Iopamidol (Jopamiron 200) is a new water-soluble, non-ionic contrast medium for myelography, which recommends itself for reasons of safety, diagnostic effectiveness, economy and convenience. It has been used in a small series of 185 patients in doses of 10-15 ml and found to be highly satisfactory for myelography of the lumbosacral, thoracic and cervical regions.
