Another study showing link to cold temperatures

Post by webslave »

And this study takes the extra step of linking cold to muscle spasm. So we keep moving, slowly, in the right direction.

Pain associated with the chronic pelvic pain syndrome is strongly related to the ambient temperature.

Abstract Objective. There are indications suggesting that the pain associated with the chronic pelvic pain syndrome (CPPS) may be related to cold. The purpose of the present study was to evaluate how the symptom intensity reported by the patient relates to the time of the year in a temperate climate, i.e. to the ambient temperature and to weather changes. Material and methods. Thirty-one patients, mean age 51 years (range 35-66 years), with CPPS for 17 ± 10 years (3-42 years) were asked to complete a set of questionnaires including questions concerning how they experienced their symptom intensity during the different seasons using the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) questionnaire. Results. The total NIH-CPSI score was 22.2 ± 8.2. There was a highly marked relationship between season and pain intensity as reported by the informants: it was experienced to be three times more intense during the winter months. All subjects reported that a temperature drop was associated with deterioration. Conclusion. The strong relationship between the ambient temperature, a drop in temperature and the pain experienced by men with CPPS confirms the association between cold and symptom intensity in the Scandinavian countries, where the seasonal temperature variation spans a long range and the winters are long. The cause of this relationship is still to be established. Muscular spasm/stiffness is a possibility that remains to be explored.

Seasonal changes in symptoms in patients with chronic prostatitis/chronic pelvic pain syndrome: a seasonal follow-up study.
Shin JH1, Lee G.

Aim: The aim of this study was to evaluate whether seasonal changes aggravate the symptoms of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), by serial administration of the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) questionnaire for an extended period.

Material and methods: Seventy-seven men with CP/CPPS were serially evaluated with the Korean version of the NIH-CPSI questionnaire every 2-3 months from October 2008 to October 2012. The mean duration of follow-up was 27.11 ± 10.00 months and the mean number of visits per patient was 14.68 ± 5.33 times during the study.

Results: The number of patients complaining of breakthrough pain during the study was 31 in spring and autumn, nine in summer and 18 in winter. However, there were no significant differences in the mean NIH-CPSI scores across the seasons. In spring, summer and autumn, only urination symptoms correlated with quality of life (QoL) (r2 = 0.277, p < 0.001). In winter, both pain items and urination symptoms correlated with QoL (pain: r2 = 0.522, p < 0.001; urination symptoms: r2 = 0.250, p < 0.001).

Conclusion: Although fewer severe pain attacks occurred in summer, the mean NIH-CPSI scores did not differ across seasons. The pain from CP/CPPS had a greater impact on QoL during winter than it did in the other seasons. In addition, pain was a more significant determinant of QoL than urination symptoms during winter.
