Abstract:

Introduction: Human T cell Lymphotropic Virus Type I (HTLV-I) associated infective dermatitis (IDH) is characterised by exudation and crusting around the nostrils, ears and scalp. Other than its description, not much else is known about the entity of IDH, now accepted to be more common in Latin America and the Caribbean. Pathogenetic mechanisms behind the development of the dermatitis in IDH remain to be elucidated. There are no data addressing the possible effect that HTLV-1 infection may have on the skin.

Aim: The objectives of this study were to investigate if IDH patients have the same atopic tendencies as atopic dermatitis (AD).

Method: In a study of 14 cases with IDH from South Africa and their controls which included five AD patients, five asymptomatic carriers (ACs), and 18 healthy uninfected individuals, we conducted a clinical assessment. We measured total IgE levels together with allergen specific IgE levels to house dust mite. Skin samples of cases with IDH and that of controls without AD was stained for filaggrin protein. The clinical examination, the IgE tests, filaggrin staining were all conducted in search of a possible association with an atopic diathesis in patients with IDH. We then measured the proviral loads in the DNA of patients with IDH comparing with them with ACs. We stained the skin sections to investigate the frequency and phenotype of the cellular infiltrate in the skin of patients with IDH.

Result: The clinical outcomes in this study revealed evidence of dry skin, scarring alopecia, significant visual disturbances but no asthma in IDH cases compared to controls. The cohorts with IDH neither have anemia nor lymphocytosis but an elevated ESR. Patients with IDH neither have elevated allergen-specific IgE nor clinical evidence of associated atopic disease. Filaggrin protein was down-regulated in the skin of cases with IDH. A high proviral load was noted in IDH cases compared to ACs. We identified a strong lymphocytic infiltrate which did not confine itself to the dermis but extended into the epidermis. A significant proportion of this infiltrate were in keeping with the CD4+FoxP3+ T cell phenotype in lesional skin of IDH cases as opposed to uninfected individuals.

Conclusions: In summary, this preliminary data shows that IDH is not associated with an atopic diathesis. FLG protein in the epidermal skin of IDH patients is down-regulated which may contribute to barrier dysfunction. Furthermore CD4+FoxP3+ T cells are enriched in the blood and skin of individuals with IDH, compatible with a role for such cells in disease pathogenesis.

Abstract:

Atopic dermatitis (AD) is one of the most common chronic inflammatory skin diseases that affect both children and adults with a prevalence of 30% and 10%, respectively. Even though most of patients respond satisfactory to topical anti-inflammatory drugs, about 10% require one or more systemic treatments to achieve good control of their illness. The progressive knowledge in the immune-pathogenesis of AD has allowed research on new therapeutic targets with very promising results in the field of biological therapy. In my talk, I will review the different biological treatments with a focus on novel drugs, their mechanism of action, side effects and results from different clinical trials and studies.

Abstract:

Anaphylaxis is a potentially life-threatening condition. We have aimed to characterize clinical profiles and triggers in patients with anaphylaxis who presented at the Queen Medical Center, Doha during December 2014 to May 2016. 38 patients (14 males and 24 females) were evaluated including four children. Among the patients, 10 (26.3%) were Qatari and 28 (73.7%) were non-Qatari [17 (44.7%) Arabs, 7 (18.4%) Caucasians and 4 (10.5%) Asians]. Drugs, were the causative agents in 18 (47.4%) of cases, foods in 11 (28.9%), insect stings in 7 (18.4%) and 2 (5.3%) were of unknown aetiology. The sites of clinical manifestations in order of frequency were cutaneous in 37 cases (97.4%), respiratory in 31 (81.6%), cardiovascular in 26 (68.4%) and gastrointestinal in 17 (44.7%). Among all reactions, 5 (13.2%) were fatal and 16 (42.1%) were life-threatening. The fatal reactions were in response to injection of drugs (pethidine, morphia, lidocaine and iron infusion) but unknown aetiology in one case. NSAIDs, iron infusion and seafoods were the most common triggers of severe reactions (3 of each). Of the 38 patients, 22 (57.9%) reported other co-existing allergic diseases with rhinoconjunctivitis the most common (11; 28.9% patients). Our findings implicate drugs as the major triggers of fatal and severe anaphylaxis in our patients followed by seafood. Our findings highlight the importance of anaphylaxis in Qatar and indicate the range of triggers for this serious condition.

Abstract:

Background: Psoriasis is associated with high levels of psychological distress and considerable life impact. The impact of psoriasis, beyond the skin, is often not recognized and under-treated.

Objectives: To assess the prevalence of anxiety in patients diagnosed with psoriasis according to standard criteria.

Methods: The study was a cross-sectional survey conducted in three hospitals in Riyadh region over a period of 6 months from October 2013 to March 2014, using a self-administered questionnaire. The general part of the questionnaire is composed of 10 questions that covered the demographic, behavioral and clinical characteristics. Anxiety was assessed using the 14-items Hamilton Anxiety Scale. The severity of anxiety symptoms was categorized into mild (<17), moderate (18-24) and severe (25-30) anxiety. Out of 250 distributed questionnaire, 219 responded (response rate of 87.6%).

Result: The age of the patients ranged between 10 and 60 years, 54.8% were females and 53.4% were not-married. Out of 219 examined patients, 150 (68.5%) were found to have mild anxiety, 51 (23.3%) with moderate anxiety, 18 (8.2%) with sever anxiety. Severe anxiety was considerably seen more among those who were between 20 and 39 years (15.2%) compared to those <20 years (0%) and those between 40 and 60 years (5%). Severe anxiety was significantly higher among patients with longer duration of the illness. There was no significant association between the psoriasis severity and the severity of anxiety symptoms.

Conclusions: The current study reported high prevalence of anxiety symptoms among patients with confirmed psoriasis in Riyadh Hospitals, Saudi Arabia.

Abstract:

Inability of topical medications to penetrate via nail plate brings a great challenge to clinicians in treating onychomycosis. Furthermore, oral medications are not appropriate for all patients because of drug interactions, adverse effects and contraindications. We sought to evaluate the clinical efficacy of fractional carbon-dioxide laser-assisted topical therapy for onychomycosis. In total, 75 patients with 356 onychomycotic nails confirmed by mycologic examination were included in this study. All the affected nails received 3 sessions of laser therapy at 4-week intervals and once-daily application of terbinafine cream for 3 months. In all, 94.66% and 92% of the treated patients were potassium hydroxide and culture negative, respectively, after 3 months of treatment. However, only 84% and 80% were potassium hydroxide and culture negative, respectively at 6 months of follow-up. Using Scoring Clinical Index for Onychomycosis electronic calculator, 73.33% of the patients scored higher than 6 and 26.66% of the patients scored 6 or less. Those who scored more than 6 were evaluated clinically and 98.18% of them showed response to treatment at 3 months and 78.18% of them at 6 months of follow-up. Lack of control group and short duration of follow-up are limitations. Fractional carbon-dioxide laser therapy combined with topical antifungal was found to be effective in the treatment of onychomycosis. However, randomized clinical studies are needed before it can be widely used in clinics.

Abstract:

Objective: To develop a new pigmented/non-pigmented skin questionnaire and to compare its reliability and validity with the Baumann’s skin questionnaire in adults in China.

Methods: A new pigmented/non-pigmented skin questionnaire (Huaxi questionnaire) was developed and 695 adults in Chengdu were included by a simple random sampling method to fill in both the Huaxi questionnaire and the Baumann’s skin type questionnaire. 100 respondents among the 695 adults were randomly selected to complete the 2^nd test after 2 weeks. SPSS 22.0 statistical software was adopted to evaluate the internal consistency reliability, test-retest reliability and construct validity.

Results: The Baumann’s skin type questionnaire had a Cronbach's α coefficient of 0.745, while the Huaxi questionnaire had a Cronbach's α coefficient of 0.780, both of them showed acceptable internal consistency. The retest reliability ‘r’ of the Baumann’s skin type questionnaire and the Huaxi questionnaire were 0.735 and 0.936, respectively. Four common factors were extracted in the Baumann’s skin type questionnaire by factor analysis that accounted for 55.77% of total variance, while three common factors were extracted in the Huaxi questionnaire that accounted for 62.76% of total variance. The factor loads of some items that were extracted in the Baumann’s skin type questionnaire had values less than 0.4, which should be deleted.

Conclusion: The version of Baumann’s skin type questionnaire in China has a good reliability and validity but the items should get further modification to ensure the reliability and effectiveness of its measurements. The Huaxi questionnaire appeared to be more preferable and suitable than the Baumann’s skin type questionnaire on evaluation of pigmentation type of facial skin in adults.

Abstract:

Traditionally, ROS have been implicated in the progression of various kinds of inflammatory diseases, including atopic dermatitis (AD) and psoriasis but several opposing observations suggest the protective role of ROS in inflammatory diseases. Many inflammatory diseases were aggravated in rodents and human with lowered levels of ROS, such as Ncf-1^-/-, NOX2^-/- mice and CGD patients, whereas attenuated in those with elevated levels of ROS, such as Gpx-1^-/- and Prx II^-/- mice, suggesting the anti-inflammatory role of ROS. In particular, the suppressive function of regulatory T cells (Tregs) seems to be closely linked to ROS level; Ncf1^-/- Tregs were hypofunctional, while Gpx1^-/- Tregs were hyperfunctional. Based on this background, we investigated animal models of AD and psoriatic dermatitis (PD) in mice with elevated or lowered levels of ROS, such as Ncf-1^-/-and Gpx1^-/- mice, or WT mice treated physically or chemically that may increase or decrease tissue levels of ROS; hyperbaric oxygen therapy or an oxygen-carrying chemical, perfluorodecalin increases, whereas antioxidants, such as N-acetylcysteine (NAC) or ascorbic acid decrease tissue ROS level. The results consistently showed appropriately elevated levels of ROS attenuated, whereas lowered levels of ROS aggravated, murine models of AD and PD. Correlation of Treg function with ROS level was also demonstrated in vitro by using DMNQ or NAC. In the present study, two molecules that may link ROS level and Treg function were investigated; Indoleamine 2,3-di-Oxygenase and Hypoxia-inducible factor-1α. The results of the present study suggest the potential therapeutic effect of oxygen therapy for inflammatory skin diseases.

The frequency and severity of atopic disease is increasing in Qatar. We have aimed to determine characteristics of patients with severe forms of atopic asthma, rhinoconjunctivitis and atopic dermatitis in adult Qatari and non-Qatari residents who presented at Queen Medical Center, Doha from January 2015 to May 2016. A total of 31 adult patients (11 males) with severe atopic conditions attended outpatient clinics and ER during the defined period. Among the patients, 5 (16.1%) were Qatari and 26 (83.9%) were non-Qatari [11 (35.5%) Arabs, 7 (22.6%) Caucasians, 7 (22.6%) Asians and 1 (3.2%) African]. A family history of atopy was present in 17 (54.8%) patients with asthma the most common conditions reported (in 12 patients; 38.7%). Severe asthma was diagnosed in 14 (45.2%) patients, severe rhinoconjuctivitis in 11 (35.5%) and severe atopic eczema in 6 (19.6%). Overall, 21 (67.7%) patients had one severe atopic condition while 10 (32.3%) had other atopic manifestations as well with severe rhinoconjuctivitis commonly associated with asthma. Only three of the patients surveyed had all three of these atopic conditions. Eight patients (25.8%) reported that the condition had an onset or worsening in adulthood; in seven of them, it was coincident with residency in Qatar; possibly related to the local environment or climate. Generally, dust was mentioned as the most common trigger factor, followed by pollens and grass, strong smells and animal dander. Patients with severe atopic dermatitis were likely to have allergies other than classic atopy; penicillin allergy, food allergy and contact dermatitis (each reported in 2 patients). Our findings indicate that severe atopic disease is an important public health problem in Qatar. There will be a need for improvement in prevention and management plans.

Abstract:

Aquagenic Wrinkling of the Palms (AWP) is a rare dermatologic disease. It was first described four decades ago as a potential test for Cystic Fibrosis (CF) by detecting “skin wrinkling” in response to water immersion. We are reporting two cases of AWP diagnosed at Derma Clinic, Riyadh, Saudi Arabia. The first case was a nine year old girl and the second case was a 17 year old adolescent male. The second case was associated with palmer hyperhidrosis. Both patients denied any medication use. Additionally, signs and symptoms suggesting CF were lacking. Local dermatologists should be aware of rare conditions such as AWP and lack of previous reports from the region may indicate under-reporting rather than lack of cases.

Abstract:

Background & Aim: Stevens-Johnson syndrome (SJS) is one of the most dreaded drug related complication leading to extensive mucocutaneous involvement in severe cases and long term complications. This group of disease is related to certain medication groups however we report a substantial number of non-drug related cases as well. The aim of this study was to look into various causes and outcome of SJS in children presenting to our institute.

Method: A 10 year retrospective review was done on all the cases coming to the Aga Khan University Hospital, variables like etiology, clinical characteristic, treatment and outcome were entered on a predesigned profoma and frequencies were analyzed on SPSS 17.

Results: Total sample size of 97 patients was analyzed; 69 patients presented with generalized rash (more than 10% of body involvement with mucositis) and 12 had localized disease (less than 10% skin involvement) 16 patents were categorized as in between category. Exposure to drugs 77 (79.4%), 20 (20.6%) cases were categorized as non-drug related. Out of drug group 52% were exposed to antibiotics, 22% were given antimalarial and 10.5% were given antiepileptic medication. Among the therapeutic interventions intravenous steroids were given 30%, IVIG 2% either alone or in combination rest were managed with supportive care. 23.7% developed systemic complications (AKI 12.6%, sepsis 46%, Pneumonia 13%, and one case developed ocular complication while in hospital. Outcome was classified at the dime of discharge fully resolved 10.6%, partial resolution 71%, mortality 14.4%.

Conclusion: Drug related dermal complications like SJS are predominantly attributed to antibiotics, antimalarial and antiepileptic drugs however non drug related presentations also contribute to significant number of cases. Delay in recognition leads to systemic complications morbidity and mortality if not treated on time.

Abstract:

Skin lightening products are widely used by people with hyperpigmentary skin disorders. The most effective molecules used in these products were hydroquinone, mercury and corticosteroids. These chemical compounds are banned to be used in cosmetic products because they can be harmful to human health. We investigated the Rapid Alert System (RAPEX) database from January 2005 until December 2014 to give information about the safety of skin lightening products in European markets. 124 cosmetic products contained hydroquinone in concentration from 0.06 to 7.1%. Hydroquinone was found in skin lightening products (90.32%) body lotions, (8.06%) body oils (0.81%) and hair creams (0.81%). The country of origin of the products was Democratic Republic of Congo, Ivory Coast, United States, France, United Kingdom, Poland, Germany, Belgium and Jamaica. A large number of cosmetics were contaminated by heavy metals: Lead, mercury, antimony, chromium, cadmium, arsenic and nickel. In 45 cosmetic products mercury was present in skin lightening products in concentration from 9.1 mg/kg to 42000 mg/kg. Lead was found lipsticks, make-up, children products in concentration up to 16900 mg/kg. Skin lightening products with clobetasol propionate were also recalled during the period. As a conclusion we can say that people with hyperpigmentary skin disorders are exposed by the risk of chronic use of prohibited chemical compound in skin lightening products.
