Measuring Quality of Life in Hidradenitis Suppurativa: Development and Validation of a Disease-specific Patient-reported Outcome Measure for Practice and Research.

Hidradenitis suppurativa is a chronic disease that disrupts patients' physical and psychological well-being. A disease-specific measure was developed and validated for assessing health-related quality of life in hidradenitis suppurativa. After qualitative item development, the quality of life in hidradenitis suppurativa instrument was tested in 101 patients, applying convergent measures and a usability questionnaire. Descriptive and validation-specific analyses were conducted. There was no ceiling, but moderate floor effects (scores between 0 and 3.13 on a scale of 0-4). Few missing values were observed (21 of 23 items < 5%). Internal consistency was satisfying: 2 subscales with 6 and 16 items were identified (Cronbach's alpha=0.95 and 0.88). The quality of life in hidradenitis suppurativa instrument correlated significantly with all convergent criteria (including change in convergent patient-reported outcomes; p < 0.05) except for Hurley stage (p = 0.490). In conclusion, the quality of life in hidradenitis suppurativa questionnaire is an internally consistent, valid, responsive, and usable instrument to assess quality of life in patients with hidradenitis suppurativa.

Non-fracture acute compartment syndrome in the upper extremity of a 14-year-old boy: A case report and review of the literature.

INTRODUCTION: Acute compartment syndrome (ACS) is an orthopaedic emergency affecting all age groups, yet diagnosis proves particularly difficult within the paediatric population and especially in the absence of fractures. CASE PRESENTATION: In this case report, we detail a rare instance of a non-fracture acute compartment syndrome (NFACS) in a 14-year-old boy, initially missed due to lack of suspicion. Symptoms included swelling, severe pain, and initial paresthesia in the hand. Despite prompt forearm fasciotomy, severe post-traumatic Volkmann contracture ensued, resulting in limited upper extremity function despite multiple corrective surgeries. CLINICAL DISCUSSION: Acute compart syndromes, occurring without fractures, often faces delayed diagnosis, particularly in paediatrics population. Clinical examination remains the diagnostic gold standard, with analgesia refractory pain warranting suspicion. Additional diagnostic criteria like ultrasound, MRI or CK blood values can be evaluated with reservation, especially in the paediatric population. CONCLUSION: This case highlights the importance of increased vigilance in diagnostics for NFACS especially in children, in order to not overlook NFACS, due to the wide variability in the aetiology and clinical appearance. We emphasize the relevance of clinical diagnostics and point out an increased awareness of NFACS in analgesic refractory pain.
