RESUMEN
A retrospective study was done on blood donated at Department of Transfusion Medicine, Siriraj Hospital from 1987 to 1996. The total number of 274,288 units were donated from three types of blood donors : voluntary (61.31%), replacement (35.57%) and paid (3.12%) during 1987-1993. The serological infectious disease markers were found to be highest in replacement donors. The prevalence of anti-HIV, HIV antigen, HBsAg, anti-HCV and positive VDRL were 0.7%, 0.02%, 6.2%, 1.6% and 2.3% respectively. The prevalence of these markers in voluntary donors were 0.3%, 0.01%, 2.6%, 0.9% and 1.0% respectively. In conclusion, the serological infectious disease markers in blood donated at Siriraj Hospital during the 10 years period consisted of 0.44% anti-HIV, 0.01% HIV antigen, 3.7% HBsAg, 1.13% anti-HCV and 1.40% positive VDRL. It was also noted that the prevalence of these markers in new blood donors were higher than those found in repeat blood donors.
RESUMEN
Four cases of fungal sinusitis are reported. These include one case of aspergillus sinusitis alone, one case of combined aspergillus and paecilomyces sinusitis, and two cases of mucormycotic (zygomycotic) sinusitis. Although fungal sinusitis appears to be rare, it can pose difficulty in clinical diagnosis and we have demonstrated how the pathologist can help to alert the otolaryngologists of possible fungal sinusitis. Since the histopathological examination is important, a specimen for biopsy is mandatory.
