Fever is not a symptom of chronic rhinosinusitis.

INTRODUCTION: In the chronic rhinosinusitis (CRS) definition of the RhinoSinusitis Task Force (RSTF) of the American Academy of Otolaryngology-Head and Neck Surgery, fever is one of the minor symptoms. In the EP3OS definition, fever is not mentioned as a contributing factor. The main aim of this study was to evaluate the role of fever in CRS. PATIENTS AND METHODS: Patients with CRS, scheduled for surgery were compared with a control group consisting of patients without CRS, suffering from esthetic complaints or obstruction of the nose. Temperature prior to surgery was measured and analyzed. RESULTS: In both groups, hundred patients were included. In the CRS group the mean temperature was 36.94 degrees C, with a maximum of 37.8 degrees C. The control group revealed a mean temperature of 36.87 degrees C. Analysis demonstrated no significant difference between the mean temperatures of the CRS patients and the controls (p = 0.306). Additional analysis, correcting for possible confounders, did not reveal significant differences between both groups either. DISCUSSION: There have been several attempts to define CRS in the past, but an all including definition or classification system for this disorder does not currently exist. Fever is a factor under discussion. We found no significant difference between the preoperative body temperature in CRS patients and controls. These results suggest that fever is not a relevant symptom in CRS.

Association between valgus and varus alignment and the development and progression of radiographic osteoarthritis of the knee.

OBJECTIVE: Although knee malalignment is assumed to correlate with knee osteoarthritis (OA), it is still unknown whether malalignment precedes the development of OA or whether it is a result of OA. The aim of this study was to assess the relationship between malalignment and the development of knee OA as well as progression of knee OA. METHODS: A total of 1,501 participants in the Rotterdam study were randomly selected. Knee OA at baseline and at followup (mean followup 6.6 years) was scored according to the Kellgren/Lawrence (K/L) grading system. Alignment was measured by the femorotibial angle on radiographs at baseline. Multivariable logistic regression for repeated measurements was used to analyze the association of malalignment with the development and progression of OA. RESULTS: Of 2,664 knees, 1,012 (38%) were considered to have normal alignment, 693 (26%) had varus alignment, and 959 (36%) had valgus alignment. A comparison of valgus alignment and normal alignment showed that valgus alignment was associated with a borderline significant increase in development of knee OA (odds ratio [OR] 1.54, 95% confidence interval [95% CI] 0.97-2.44), and varus alignment was associated with a 2-fold increased risk (OR 2.06, 95% CI 1.28-3.32). Stratification for body mass index showed that this increased risk was especially seen in overweight and obese individuals but not in non-overweight persons. The risk of OA progression was also significantly increased in the group with varus alignment compared with the group with normal alignment (OR 2.90, 95% CI 1.07-7.88). CONCLUSION: An increasing degree of varus alignment is associated not only with progression of knee OA but also with development of knee OA. However, this association seems particularly applicable to overweight and obese persons.
