Behçet's disease (BD) is a chronic inflammatory multisystemic disorder characterized mainly by vasculitis. Although the pathergy reaction (PR) has been accepted as one of the major criteria in this disease, there is a lack of a standardized method to measure PR. The aim of this study was to evaluate results of PR in different body areas and the effect on the positive rate of PR of application of numerous needle pricks. The pathergy test was performed using simultaneous 16 needle pricks with 20G disposable needles on different body areas of 56 patients with BD, 49 patients with recurrent aphthous stomatitis (RAS) and 17 healthy subjects. No positive PR was found in healthy controls, but was observed in nine patients with RAS (18.3%). It was detected in 48 of 56 patients with BD, a positive rate of 85.7%. The site most frequently positive for PR was the forearm, while the least frequent was the abdomen. Multiple needle pricks could play an important role in increasing the positive rate of PR in BD, and it may be important in the investigation of aetiological factors in RAS.

Tear secretion, tear film stability, and meibomian gland function (plugging, volume, and thickness) were assessed in patients with psoriasis vulgaris (n = 70). As compared to that of the healthy controls (n = 125) mean Schirmer I value of psoriatic patients was found to be in normal ranges, whereas tear film break-up time was significantly lowered. When evaluating meibomian gland function, psoriatic patients were found to have higher plugging and thickness indices but a normal volume of meibomian gland secretion. These findings suggested an obstructive type of meibomian gland dysfunction in psoriatic patients which might result from increased turnover of the epithelia lining the meibomian gland duct.

There are a few studies in the literature about dermatology consultations requested from Pediatrics Department. In the present study, it was aimed to assess the clinical features, pre-diagnosis and dermatologie diagnosis of patients consulted to the Dermatology Department from Pediatrics Department, and also to detect possible different approaches between the clinics. Methods: The list of dermatology consultations requested from Pediatrics Department between 1 September 2016 and 1 September 2017 were retrospectively evaluated by means of pre-diagnosis, dermatological diagnosis and unit consultations. Results: The mean age of patients was 7.4±5.3 years. Of the 628 patients, 52.1% were males, and 85% of the consultations were requested from outpatient clinics and 15% were from the inpatient clinics. Among all consultations 28.7% general pediatrics unit and 17.5% pediatric emergency unit required consultations. The most common diagnosis reported from Dermatology Department were eczema (28.2%), viral diseases (13.2%), parasitic diseases (8.4%) and fungal diseases (5.4%). Although, the ratio of an accurate pre-diagnosis was significantly higher in consultations requested from the inpatient clinics than those from outpatient clinics(p<0.001), 42.7% of the patients were referred to Dermatology Outpatient Clinic with an incorrect pre-diagnosis. Conclusion: Almost half of the patients, who were referred to Dermatology consultation, were diagnosed with incorrect pre-diagnosis. It was seen that pediatricians were difficult to recognize dermatoses. The awareness of Pediatric Dermatology Department should be raised for both specialties.
