    Evaluation of application of multiple needle pricks on the pathergy reaction
    (WILEY, 2008) Ozdemir, Mustafa; Bodur, Said; Engin, Burhan; Baysal, Ibrahim
    Background The pathergy reaction (PR) to a needle prick is a well-known feature of Behcet's disease (BD). Although PR is accepted as a major criterion in this disease, there is a lack of a standardized method to measure PR. The aim of this study was to evaluate the effect on the positive rate of PR of the application of numerous (one to six) needle pricks. Methods Six needle pricks were performed on 105 patients with BD. The results of the test were noted from the proximal to the distal region for each area of each patient. The positive rates of all combinations (one, two, three, four, five, and six needle pricks) were calculated as percentages by a computer-based program (SPSS version 13 for Windows), and the mean percentage rates were obtained. Results There was an increase in the percentage of positive PR rates in each combination relative to the former combination. When one needle prick was performed, the mean percentage positive PR rate was 13%. The positive PR rates were 19%, 24%, 28%, 30%, and 33% for two, three, four, five and six needle pricks, respectively. The greatest increase in the mean percentage of positive PR rates was detected for the application of the two needle prick combination. Conclusion There is no consensus about the number of needle pricks required to detect PR, and multiple needle pricks have been used in many studies. We suggest that two needle pricks are suitable for the PR skin test as a useful adjunct to the diagnosis of BD.

    A Randomized Comparison of Acitretin-narrow-band TL-01 Phototherapy and Acitretin-Psoralen plus Ultraviolet A for Psoriasis
    (ACTA DERMATO-VENEREOLOGICA, 2008) Oezemir, Mustafa; Engin, Burhan; Baysal, Ibrahim; Mevlitoglu, Inci
    The combination of retinoids with phototherapy enhances the efficacy of phototherapy and reduces the cumulative ultraviolet dose and duration of the therapy needed to treat chronic plaque psoriasis. Although TL-01 phototherapy has been used widely, there are few data about the effectiveness of the combination of acitretin with TL-01 in treatment of the disease. The aim of this study was to compare acitretin-narrow-band TL-01 phototherapy with acitretin-psoralen plus ultraviolet A (acitretin-PUVA) in psoriasis. We studied 60 patients with moderate to severe plaque psoriasis who were randomly allocated to three times weekly treatment acitretin-narrow-band TL-01 or acitretin-PUVA. The efficacy of treatments was assessed using the Psoriasis Area and Severity Index by a blinded observer. Clearance of psoriasis was achieved in 56.6% of patients treated with acitretin-narrow-band TL-01 and in 63.3% of those treated with acitretin-PUVA. All of these patients remained clear of psoriasis 3 months after finishing the treatments. Mucocutaneous side-effects, such as dry lips and mouth, were the most common complaints in both groups. In conclusion, acitretin-narrow-band TL-01 is an effective and well-tolerated treatment for moderate to severe plaque psoriasis, with a therapeutic effect equal to that of acitretin-PUVA.

    Treatment of Angiokeratoma of Fordyce with Long-Pulse Neodymium-Doped Yttrium Aluminium Garnet Laser
    (WILEY-BLACKWELL PUBLISHING, INC, 2009) Oezdemir, Mustafa; Baysal, Ibrahim; Engin, Burhan; Oezdemir, Suna
    Angiokeratomas are typically asymptomatic, blue-to-red papules with a scaly surface located on the scrotum, shaft of penis, labia majora, inner thigh, or lower abdomen. The treatment of angiokeratomas may be necessary if they bleed and lead to patient anxiety. To determine the safety and effectiveness of long-pulse 1,064 neodymium-doped yttrium aluminium garnet (Nd:YAG) laser for the treatment of angiokeratomas of Fordyce. Ten consecutive patients with angiokeratoma of Fordyce were treated with long-pulse Nd:YAG laser in two to six sessions. The three authors independently assessed improvement of the lesion based on digital photographs taken before the treatment and 2 months after the end of the treatment. Significant (> 75%, < 100%) and moderate (> 50%, < 75%) improvement was seen in six and two patients, respectively. Complete improvement was achieved in one patient. Transient swelling, purpura, bleeding, and some pain in the treated area were noted in all patients as short-term side effects. There were no permanent side effects. The long-pulse Nd:YAG laser is a highly effective and safe treatment for angiokeratoma of Fordyce. The authors have indicated no significant interest with commercial supporters.
