ABSTRACT
Chronic spontaneous urticaria has a substantial impact on patients' quality of life. The first disease-specific tool to assess quality of life impairment in this condition, the Chronic Urticaria Quality of Life Questionnaire (CU-Q2oL), was developed recently. The aim of this study was to adapt the original Italian version to the Turkish language and to evaluate its reliability, validity, and sensitivity to change. The Turkish version was developed by performing forward- and back-translation. It was then applied to 140 consecutive patients with chronic spontaneous urticaria, along with the Dermatology Life Quality Index and the Skindex-29. Disease activity was assessed using the Urticaria Activity Score. Sensitivity to change was measured in 101 patients, who completed the instruments twice at intervals of 4 weeks. Confirmatory factor analysis demonstrated that the six-scale structure of the original Italian version ("pruritus", "swelling", "impact on life activities", "sleep problems", "limits", "looks") can be retained in the Turkish instrument. Analysis regarding convergent validity showed good correlations of the Turkish CU-Q2oL with the other instruments. In addition, it was found to discriminate well between patients with different levels of urticaria activity, and to be sensitive to change. In conclusion, the Turkish version of CU-Q2oL is a reliable, valid, and sensitive instrument, which will help to characterize better the clinical impact of chronic spontaneous urticaria and treatment outcomes in Turkish patients. Its identical scale structure to that of other CU-Q2oL instruments makes it ideal for cross-cultural comparisons and for its application in future national and multinational studies.

Recent concerns have arisen about the specificity and interpretation of the autologous serum skin test (ASST), suggesting that ASST might produce false-positive results, and proposing the use of autologous plasma (APST) instead for intradermal testing in autoreactive urticaria. We investigated autoreactivity to autologous plasma and compared the results for reproducibility, sensitivity, specificity and accuracy and evaluated their association with quality of life and anti-TPO antibodies. 70 adults with chronic spontaneous urticaria (CU) and 62 controls underwent testing with ASST and APST and the tests were repeated two days after the first visit. Blood tests measured anti-TPO levels. Disease activity was assessed by urticaria activity score (UAS-7) and quality of life impairment was assessed by DLQI and CU-Q(2)oL. There were no statistically significant differences between ASST (+) and ASST (-) and also APST (+) and APST (-) patients with regard to disease duration, anti-TPO antibodies, urticaria activity scores, DLQI scores and CU-Q(2)oL scores. The results of first ASST and APST were well correlated with the results of second ASST and APST. The specificity of the two tests was similar, while ASST had a higher sensitivity and accuracy. Our results showed that there is no need to use autologous plasma instead of autologous serum for intradermal testing in CU.

Pigmented purpuric dermatoses are a group of dermatoses characterized clinically by pinpoint petechia and purpura on a brown, red or yellow base. Five diseases are included in the group of pigmented purpuric eruptions which significantly overlap clinically and histologically. Phototherapy in various forms of purpuric dermatoses has been reported in literature previously. Here we present a case of pigmented purpuric lichenoid dermatitis which rapidly cleared with narrowband UVB therapy.

Reticulate Acropigmentation of Kitamura (RAPK) was first described in Japan and most cases reported have been in patients of Asian ethnic groups. Angulated, slightly atrophic, hyperpigmented macules that are arranged in a reticulate pattern are typically found on the dorsal hands and feet. The condition is inherited in an autosomal dominant fashion and skin changes begin to develop during childhood. We report RAPK in a mother and daughter who are from a non-Asian ethnic group.

Prolidase deficiency is an autosomal recessive disorder that is associated with chronic cutaneous ulcers, mental retardation, unusual facial appearance, skeletal deformities, joint dislocations, hematological anomalies, splenomegaly, and chronic infections. The most typical finding is chronic, recurrent leg ulcers appearing in early childhood. Prolidase (peptidase-D) is necessary for collagen biosynthesis and its deficiency leads to impairment in connective tissue of the skin, capillaries, and lymphatic vessels. We report a 33-year-old woman who had a 15-year history of nonhealing ulcer on left pretibial region accompanied by splenomegaly, hypochromic microcytic anemia, and thrombocytopenia. Prolidase deficiency is a rare genodermatosis and must be considered in the differential diagnosis of leg ulcers that develop at an early age.

Granulomatous cheilitis (GC) is a chronic granulomatous inflammation of the lips of unknown etiology. The possible relationship with tuberculosis has been described although most of the studies excluded infectious agents as potential causes of the granulomatous response. To our knowledge only one case of granulomatous cheilitis resulting from a tuberculide has been reported in the literature but accompanying internal involvement has not been previously described. We report a case of GC resulting from a tuberculide. Investigations showed pulmonary involvement compatible with tuberculosis and improvement following antituberculous chemotherapy for 3 months.
