Allergy Prevalence

Background: Contact allergy to methylisothiazolinone (MI) or to the combination of methylchloroisothiazolinone and MI (MCI/MI) is an important and increasing cause of allergic contact dermatitis, with prevalence rates higher than 10% in some centers. Objectives: The objective of this retrospective chart review is to provide a western Canadian perspective on whether the positive patch testing rate to MCI/MI or MI increased during the testing period of 2008 to 2015 and whether the addition of MI at 2000 ppm resulted in increased detection. Methods: We conducted a retrospective chart review of patients who tested positive (n = 104) of 2177 total patients who were patch tested for MCI/MI or MI at a community dermatology clinic in Vancouver, British Columbia, Canada, from January 2008 through April 2015. Results: One hundred and four patients had positive patch testing results for MCI/MI, MI, or both. Positive results increased over the study period, with the highest prevalence in 2015 at 9.41% for MCI/MI, 12.94% for MI, and 15.29% for either. When testing for MI at 2000 ppm was introduced in 2013, the initial positive patch testing prevalence was 6.6%, followed by 10.1% in 2014, and 12.9% in 2015. Conclusions: We demonstrate an increasing prevalence of MCI/MI and MI allergy between 2008 and 2015, with the highest prevalence of 15.29% in 2015 for MCI/MI and/or MI allergy. The addition of MI 2000 ppm greatly increased the positive patch testing yield for MI. Our results support the importance of continued efforts to monitor and regulate these preservatives.

Background: Fungal infections are one of the common skin diseases with difficulty in their treatment approach. The present efficient drugs for fungal infection are limited. Aim: To determine the therapeutic efficacy of plant extracts as alternative antifungal agents. Materials and methods: 100 clinical samples [68 from female and 32 from male] were collected during the period from March to July 2017 from subjects attending Dermatology Clinic in Salah Uldean General Hospital. Fungal infection was diagnosed with using KOH wet preparation. Fungal species identified by using conventional approach. The active ingredients existing in the plant extracts were detected and analyzed through qualitative and quantitative detection technique of chemical compounds using a high performance liquid chromatographic device (HPLC). Agar diffusion method was used to determine antifungal activity of plant extracts. Results: Direct microscopic examination showed that there were (75%) positive samples, while culture shows (67%) positive samples. The isolated dermatophytes belong to Epidermophyoton, Microsporum, and Trichophyton genus. The predominant dermatophytes were T. rubrum (25%) species. The highest frequency of infection was in the age group of 11-20 years. The sensitivity of the tested fungi to the aqueous and alcoholic plant extracts varies. Alcoholic extract of the hot pepper plant was more effective as antifungal than the aqueous extract of the same plant. However, aqueous hot pepper extracts was more effective against T. mentagrophyte than that of alcoholic extract. Additionally, alcoholic Sumac extract shows higher efficacy that aqueous extract. Conclusion: Hot pepper and Sumac extracts show antifungal activity against Microsporum canis, Trichophyton rubrum and T. mentagrophyte.

Alopecia areata (AA) is a type of non-scarring alopecia first described by Cornelius Celsus, characterized by hair loss without any clinical inflammatory signs and affecting both males and females equally. The activity of AA is by the presence of black dots, broken hair, and tapering, furthermore black dots and yellow dots are equated to severity of AA. Aim - To study dermoscopic features of untreated cases of alopecia areata. Study subjects-All the patients who attended the dermatology clinic from March 2015 to March 2017 with the clinical diagnosis of alopecia areata and who fulfilled the inclusion and exclusion criteria. Study period - Two year (from March 2015 to March 2017). Methodology - All the patients who attended the dermatology clinic from March 2015 to March 2017 with the diagnosis of alopecia areata and who fulfilled the inclusion and exclusion criteria were recruited for the study. Trichoscopy was performed with DL4 dermatoscope. The images were further magnified with smart phone. Results - We got various dermoscopic signs in different combinations in our study. Yellow dots were seen in 10 cases, White dots in cotton wool pattern were seen in 3 cases, Black dots were seen in 25 cases, Dermoscopic coudability sign was demonstrated in 38 cases, Pigtail hairs were present in 2 cases, five cases showed short vellus hairs, Short broken hairs were found in 18 cases, Exclamation mark hairs were very common and were detected in 131 patients out of 138. Discussion - Single feature is not leading to the diagnosis so we should use combination of features which will help in difficult cases like AA incognito. Dermatoscope is an indispensible valuable tool in trichology practice which helps in prognosticating and making early diagnosis of AA. It also helps to differentiate it from trichotillomania and other causes of alopecia. In our study the incidence of AA was almost similar in both sexes. Our study revealed that exclamation mark hair is very common and sensitive dermoscopic marker of AA.
