Trends in the detection of causative pathogens and changes in bacterial counts in patients with sinusitis treated between January 1989 and December 1993 were investigated. In adult patients with chronic sinusitis, Staphylococcus aureus (S. aureus), coagulase negative staphylococci (CNS), Streptococcus pneumoniae (S. pneumoniae), Corynebacterium sp., Haemophilus influenzae (H. influenzae), and Moraxella catarrhalis were often isolated while Pseudomonas aeruginosa (P. aeruginosa) and anaerobic bacteria were detected in 2.4% and 5.3% of patients, respectively. The bacteria isolated from adult patients with acute sinusitis and pediatric patients with either acute or chronic sinusitis were somewhat different from those of adult chronic sinusitis. No bacteria could be isolated from 5.8% of adult chronic sinusitis patients, 8.1% of adult acute sinusitis patients, and 3.1% of pediatric sinusitis patients. The detection rate for anaerobic bacteria has been rising in chronic sinusitis patients owing to improved detection techniques in recent years, while there has been no appreciable change in the isolation rate for other types of bacteria. When the pathogenicity of isolated bacteria was determined based on the amount of bacterial colonization it was found that P. aeruginosa, S. pneumoniae, H. influenzae, and S. aureus were significant as causative pathogens in sinusitis, while CNS.

D010256 Paranasal Sinuses Air-filled spaces located within the bones around the NASAL CAVITY. They are extensions of the nasal cavity and lined by the ciliated NASAL MUCOSA. Each sinus is named for the cranial bone in which it is located, such as the ETHMOID SINUS; the FRONTAL SINUS; the MAXILLARY SINUS; and the SPHENOID SINUS.

D002908 Chronic Disease Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).

D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
