Clinical characteristics of generalized idiopathic pruritus in patients from a tertiary referral center in Singapore
Bibliographic record
Abstract
BACKGROUND: Generalized idiopathic pruritus is a rarely studied heterogeneous condition, where patients with non-inflamed, non-pathologic skin complain of widespread pruritus. METHODS: We had administered a detailed pruritus questionnaire, based on the short form of the McGill pain questionnaire, on 75 patients with this condition. RESULTS: All 75 patients recruited with generalized idiopathic pruritus completed the questionnaire. In 92% of the patients, pruritus appeared on a daily basis. Most patients experienced pruritus at night (56%) and in the evening (61%) and 69% had difficulty falling asleep. Pruritus mainly involved the legs (79%), arms (76%) and back (68%). Accompanying symptoms were heat sensation (17%) and pain (13%). 80% had been prescribed antihistamines, of whom 56% obtained short-term relief. The sensation of itch has been reported to be crawling (33%), tickling (20%), stinging (19%) and burning (19%). Patients also reported that the itch was unbearable (73%), bothersome (72%), annoying (67%) and worrisome (45%). The worst-state VAS scores were significantly higher in patients who reported agitation (P = 0.006), difficulty in concentration (P= 0.010) and anxiety (P= 0.033). CONCLUSION: This study describes the sensory and affective dimensions of generalized idiopathic pruritus, and this questionnaire has been found to be a useful tool for evaluating pruritus in this condition.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
