Abstract Background: Levocetirizine and desloratadine are mostly used H1-antihistamines in the treatment of allergic disease in 5 mg and 10 mg doses. Objective: In this study, the efficacy of single oral dosages of 5 mg and 10 mg desloratadine and levocetirizine were compared by using histamine-induced wheal and flare reactions. Methods: Eighty healthy volunteers were randomized for 4 double blinded treatment with desloratadine 5 mg-10 mg, levocetirizine 5 mg-10 mg. Wheal and flare responses were produced by histamine. Measurements were performed just before the ingestion of antihistamines (baseline) and afterwards at 30, 60, 240 minutes and 24 hours. The values obtained for each antihistamine were compared with baseline values. Results: It was found that, except the flare reactions at 30th minute, levocetirizine 5 mg and 10 mg suppressed histamine-induced wheal-flare reactions more than desloratadine 5 mg and 10 mg did. There were not any significant differences between desloratadine 5 mg and 10 mg in all periods. Levocetirizine 10 mg suppressed wheal-flare reactions significantly more than levocetirizine 5 mg only at 24th hour. Conclusion: In this study it was observed that levocetirizin 5 mg and 10 mg has a higher activity than desloratadine’s.

Abstract Objective: There are controversies in the treatment of seborrheic dermatitis. The aim of this study was to compare the efficacy of sertaconazole 2 % cream vs. ketoconazole 2% cream in the treatment of seborrheic dermatitis. Methods: 132 patients, with diagnosis of seborrheic dermatitis were studied. The first group received sertaconazole 2% cream (group A), and the other received ketoconazole 2% cream (group B) . At the beginning of referring and also 2 and 4 weeks after first visit, the patients were examined by a dermatologist to control improvement of clinical symptoms and drug side effects. Results: The mean age of sertaconazole and ketoconazole group was 30.18 ± 12.36 and 34.68 ± 10.16, respectively. Patients with moderate SI had the most frequency (76.6%) at pretreatment stag with ketoconazole 2% cream. This is while patients with mild SI had the highest frequency (53.3%) at post-treatment stage. In patients received the sertaconazole 2 % cream, the highest frequency was observed in 80% of cases with moderate SI at pretreatment stage while patients with slight SI had the highest frequency (83.3%) at post-treatment stage. Conclusion: Sertaconazole 2 % cream may be an excellent alternative therapeutic modality for treating seborrheic dermatitis.

Abstract Background: Acne scarring has lifelong sequelae. Fractional photothermolysis (FP) has been shown to provide fast recovery from acne within a short period, thereby aiding skin rejuvenation. Isotretinoin is a well-known, effective drug for the treatment of severe recalcitrant acne. This study investigated the safety and the efficacy of infrared fractional laser treatment in conjunction with low-dose isotretinoin for the treatment of acne and acne scars. Materials: A 1550 nm Erbium-doped fiber laser was used to treat 35 patients with acne scarring. All the patients had taken isotretinoin (10 mg/day) for more than one month prior to the commencement of the fractional laser treatment. Results: There was no aggravation of acne scars, hypertrophic scars, or keloids. Most of the patients (33 patients) received reduced microthermal damage zone (MTZ) treatment. Eighty percent of the treated patients (28 patients) demonstrated more than a fair improvement. The total average score on the global acne scarring classification before treatment was 13.5, and the score after treatment was 11.2. Conclusion: Acne and acne scars can be treated more effectively by concomitant use of an infrared fractional laser with low-dose isotretinoin with reduced MTZ densities. Most patients showed more than a fair improvement, and there was no aggravation of the scars.

The clinical efficacy of biologic agents for the treatment of moderate to severe psoriasis is well proven in clinical studies, but patients may lose response over time. Loss of response may be due to immunogenicity and the formation of anti-drug antibodies (ADA). Although data on the immunogenicity of drugs used to treat psoriasis are now emerging, more information on the impact of factors, such as dosing regimens and concomitant immunosuppressive therapy is needed. Exploring research from other disease areas where immunogenicity has long been recognised as a significant clinical issue may help in developing future strategies for using drug level and ADA measurements to help tailor biologic therapy to meet individual needs. To this end, we analyse what is known about biologics and immunogenicity in psoriasis. In order to learn from other indications, we then address the issue of immunogenicity for three different types of biologic treatments. First, factor VIII-substitution in haemophilia, where the immune system is newly exposed to a physiologic but formerly absent protein. Second, the use of biologics in inflammatory bowel disease, where similar treatment challenges apply as observed in psoriasis. Third, immunogenicity in multiple sclerosis caused by therapeutic antibodies or interferons. Immunogenicity strategies used in other disease areas will need to be tested in psoriasis before they can be widely adopted in routine clinical practice.

Background Although biologics introduced a new era in psoriasis care when available a decade ago, it is unclear to what extent the available systemic treatments treat patients adequately. Objective To analyse the clinical severity and quality of life of the psoriasis population in Sweden treated with systemics. Methods Data included 2,646 patients from the Swedish Registry for Systemic Treatment of Psoriasis. Average Psoriasis Area and Severity Index (PASI), Dermatology Life Quality Index (DLQI), and EQ-5D were reported. A subgroup of persisting moderate-to-severe psoriasis as defined by PASI≥10 and/or DLQI≥10 after >12 weeks treatment was analysed. Results Mean (SD) PASI, DLQI, and EQ-5D were 4.12 (4.57), 4.11 (5.24) and 0.79 (0.22). Eighteen percent had persisting moderate-to-severe psoriasis (n = 472). These patients were younger, had higher BMI, had psoriasis arthritis and were smoking to a larger extent (p < 0.01) compared to lower-severity patients (n = 2174). Mean (SD) EQ-5D was also considerably lower 0.63 (0.29) vs. 0.82 (0.19) (p < 0.01). Conclusion Almost one in every five patients had persisting moderate-to-severe psoriasis, despite ongoing systemic treatment. Both comorbidities and life style factors were associated with persisting moderate-to-severe psoriasis. The considerably lower generic quality of life in these patients demonstrates an unmet need. Subsequently, improved access to biologics and continuous drug development is needed in psoriasis.

Acquired trichorrhexis nodosa is a common cause of hair loss for patients of all ethnicities. It is especially prevalent in black patients with tightly curled hair types and can present unique diagnostic and therapeutic challenges due to structural differences in these hair types and the combination of various hair care and styling practices that contribute to hair damage. While scalp biopsies can help rule out other etiologies of hair loss, there is a paucity of histologic findings in acquired trichorrhexis nodosa, making this primarily a clinical diagnosis. Instead of more traditional prescription based therapies, the management of this form of hair loss emphasizes protecting the hair shaft and minimizing further damage through the development of a healthy hair care regimen. This involves appropriate selection and use of cleansing products and conditioning agents that help protect the hair from the insults of daily grooming. This paper will review the current literature on acquired trichorrhexis nodosa and will provide guidelines and recommendations for management by reviewing the different types of cleansing and conditioning products that can be used to prevent and/or halt the progression of hair breakage.
