Comparative Study
Differences among primary care patients with different mechanical patterns of low back pain: a cross-sectional investigation.
To characterise and compare a persistent low back pain (LBP) population based on 4 clinical pain patterns. ⋯ This is the first study to examine the 'Hall system' in a non-rehab primary care population. Subgroups classified according to this system appear to have distinct profiles. Further research is needed to better characterise and determine the prognostic implication of these clinically derived subgroups.

Disease-specific pain and function predict future pain impact in hip and knee osteoarthritis.
The objective of this study is to determine if osteoarthritis (OA) pain and function, persistent low back pain (LBP) and psychosocial factors predict future pain impact (PI) in people with hip and knee OA. In a population-based cohort with hip/knee OA, a standardized telephone questionnaire was used to assess baseline sociodemographics, baseline PI, patient-reported OA severity (Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) summary score), psychosocial factors (fatigue, pain catastrophizing (PC), anxiety, social network, and depression), and self-reported persistent LBP. Two years post-baseline, PI was assessed using the Pain Impact Questionnaire. ⋯ In a population-based cohort with hip/knee OA, only the baseline WOMAC summary score was an independent predictor of future PI. This suggests that treatment needs to be focused on limiting pain severity and functional limitations in individuals with hip and knee OA. However, scores for the psychosocial factors are indicative of a healthy cohort and therefore results may not be generalizable to those with poorer psychosocial health.

Prediction of hemodynamic reactivity using dynamic variations of Analgesia/Nociception Index (∆ANI).
The Analgesia/Nociception Index (ANI), a 0-100 non-invasive index calculated from heart rate variability, reflects the analgesia/nociception balance during general anesthesia. We hypothesized that dynamic variations of ANI (∆ANI) would provide better performance than static values to predict hemodynamic reactivity during desflurane/remifentanil general anesthesia. One hundred and twenty-eight patients undergoing ear-nose-throat or lower limb orthopedic surgery were analyzed in this prospective observational study. ⋯ A ∆ANI threshold of -19 % predicts hemodynamic reactivity with 85 % [95 % CI 77-91] sensitivity and 85 % [95 % CI 81-89] specificity. Dynamic variations of ANI provide better performance than static values to predict hemodynamic reactivity during desflurane/remifentanil general anesthesia. These findings may be of interest for the individual adaptation of remifentanil doses guided by ∆ANI during general anesthesia, although this remains to be demonstrated.

Comparative Study
A comparison between modified Alvarado score and RIPASA score in the diagnosis of acute appendicitis.
Acute appendicitis is a common but elusive surgical condition and remains a diagnostic dilemma. It has many clinical mimickers and diagnosis is primarily made on clinical grounds, leading to the evolution of clinical scoring systems for pin pointing the right diagnosis. ⋯ We prospectively compared the two scoring systems for diagnosing acute appendicitis in 50 patients presenting with right iliac fossa pain. The RIPASA score correctly classified 88 % of patients with histologically confirmed acute appendicitis compared with 48.0 % with modified Alvarado score, indicating that RIPASA score is more superior to Modified Alvarado score in our clinical settings.

Millions suffer from chronic vulvar pain (ie, vulvodynia). Vulvodynia represents the intersection of 2 difficult subjects for health care professionals to tackle: sexuality and chronic pain. Those with chronic vulvar pain are often uncomfortable seeking help, and many who do so fail to receive proper diagnoses. ⋯ These patterns of findings are consistent with the literature on the multidimensional nature of vulvodynia. The VPAQ can be used for assessment, diagnosis, treatment formulation, and treatment monitoring. In addition, the VPAQ could potentially be used to promote communication between patients and providers, and point toward helpful treatment options and/or referrals.
