This study investigated whether a modified Cold Provocation Test could distinguish between 86 normal subjects and 31 patients with Raynaud’s phenomenon or 59 with hand arm vibration syndrome (HAVS). Of the HAVS subjects, 56 were seen for medical reports as they were involved in litigation. Their assessments were done in a different location but the same protocol was used. A standardised cold stress was used to reduce the finger temperature to 15°C or less without inducing reflex hyperaemia. This test had acceptable repeatability for subjects without HAVS with an intra-class correlation of 0.7. Baseline temperature, temperature rise in the first 30 seconds and the time taken to rewarm by 5°C were measured. Patients with Raynaud’s phenomenon and HAVS had cooler hands than controls. HAVS patients rewarmed most in the first 30 seconds. Patients with Raynaud’s phenomenon take longer to rewarm by 5°C than controls or those with HAVS ( P<0.001). A baseline difference of >7.5°C between the temperature of the digit and that of the room is unlikely to occur in patients with Raynaud’s phenomenon or HAVS. A temperature gain of ≥2.2°C in the first 30 seconds on rewarming combined with a low baseline temperature strongly suggests HAVS. This modified cold provocation test may differentiate between patients with Raynaud’s phenomenon, HAVS and controls but this observation requires independent verification in subjects not involved in litigation and tested in the same facility.

Abstract Rheumatoid arthritis (RA) is a chronic inflammatory tissue disease that leads to cartilage, bone, and periarticular tissue damage. This study aimed to investigate whether the use of infrared thermography and measurement of temperature profiles along the hand fingers could detect the inflammation and improve the diagnostic accuracy of the cold provocation test (0 °C for 5 s) and rewarming test (23 °C for180 s) in RA patients. Thirty RA patients (mean age = 49.5 years, standard deviation = 13.0 years) and 22 controls (mean age = 49.8 years, standard deviation = 7.5 years) were studied. Outcomes were the minimal and maximal: baseline temperature (T1), the temperature post-cooling (T2), the temperature post-rewarming (T3), and the Tmax-Tmin along the axis of each finger. The statistical significance was observed for the thumb, index finger, middle finger, and ring finger post-cooling and post-rewarming. Receiver operating characteristics (ROC) analysis to distinguish between the two groups revealed that for the thumb, index finger, middle finger, and ring finger, the area under the ROC curve was statistically significantly (p < 0.05) post-cooling. The cold provocation test used in this study discriminates between RA patients and controls and detects an inflammation in RA patients by the measurement of temperature profiles along the fingers using an infrared camera.

Vibration Induced White Finger

The purpose of the study was to investigate if vibration-induced white finger may be a reversible symptom after cessation of vibration exposure. Fifty-nine welders, previously employed by a ship building company and who had shown various levels of vibration-induced vasospastic symptoms in the hand were interviewed 5 to 6 years after closure of the company. Out of the 43 patients exposed to no or insignificant vibration subsequently, 28 claimed improvement, 11 claimed unchanged problems and four complained of worse problems. Twelve of these patients had the cold provocation test repeated at follow up. One patient showed the same result as 5 years earlier, six showed improvement and five showed much improvement. Of 16 patients with continued vibration exposure none showed subjective improvement, nine claimed unchanged problems while seven patients were worse. It is concluded that vibration-induced white finger is not a progressive condition following cessation of exposure to vibration. On the contrary it may be static or even reversible to some extent.

Background: Erythromelalgia (EM) incidence has not been well studied and there are only two studies published on this subject as far as we know. The aims are to study the incidence of this rare condition in the south of Sweden, to report the clinical experience from a single centre including characterisation of comorbidity and to report on prognosis. Patients and methods: Retrospective study of a population-based analysis of data from the southernmost part of Sweden corresponding to the median age of the patients (Statistics Sweden). The diagnosis of EM is based on the medical record reflecting the triad of redness, burning pain and increased temperature of the feet or hands or both. We evaluated the presence or absence of EM triad by recording the history, physical examination, laboratory analysis, cold provocation test and laser Doppler imaging, and by searching for any confounding disease in cases of suspected EM. Results: During a 10.5 year period we clinically identified 27 patients with EM. Median age was 49 [IQR (34 - 68)] years, 19 (70 %) were women. The mean delay from the onset of the symptoms to the time of diagnosis was 4.5 (SD ± 3.9) years. Gender and age adjusted incidence of EM for our region was calculated to be 0.36 per 100 000 persons per year. Three patients developed intraabdominal cancer during the follow up, but there was no mortality directed related to EM. Conclusions: The overall population-based incidence of erythromelalgia was 0.36 per 100 000 which is identical with a previous report in a Scandinavian population.
