Dermatology Residency Selection Criteria with an Emphasis on Program Characteristics: A National Program Director Survey Mon, 17 Mar 2014 07:10:08 +0000 http://www.hindawi.com/journals/drp/2014/692760/ Background. Dermatology residency programs are relatively diverse in their resident selection process. The authors investigated the importance of 25 dermatology residency selection criteria focusing on differences in program directors’ (PDs’) perception based on specific program demographics. Methods. This cross-sectional nationwide observational survey utilized a 41-item questionnaire that was developed by literature search, brainstorming sessions, and online expert reviews. The data were analyzed utilizing the reliability test, two-step clustering, and -means methods as well as other methods. The main purpose of this study was to investigate the differences in PDs’ perception regarding the importance of the selection criteria based on program demographics. Results. Ninety-five out of 114 PDs (83.3%) responded to the survey. The top five criteria for dermatology residency selection were interview, letters of recommendation, United States Medical Licensing Examination Step I scores, medical school transcripts, and clinical rotations. The following criteria were preferentially ranked based on different program characteristics: “advanced degrees,” “interest in academics,” “reputation of undergraduate and medical school,” “prior unsuccessful attempts to match,” and “number of publications.” Conclusions. Our survey provides up-to-date factual data on dermatology PDs’ perception in this regard. Dermatology residency programs may find the reported data useful in further optimizing their residency selection process.

Epidermal Growth Factor Receptor Inhibitors: A Review of Cutaneous Adverse Events and Management Sun, 02 Mar 2014 11:19:52 +0000 http://www.hindawi.com/journals/drp/2014/734249/ Epidermal growth factor inhibitors (EGFRI), the first targeted cancer therapy, are currently an essential treatment for many advance-stage epithelial cancers. These agents have the superior ability to target cancers cells and better safety profile compared to conventional chemotherapies. However, cutaneous adverse events are common due to the interference of epidermal growth factor receptor (EGFR) signaling in the skin. Cutaneous toxicities lead to poor compliance, drug cessation, and psychosocial discomfort. This paper summarizes the current knowledge concerning the presentation and management of skin toxicity from EGFRI. The common dermatologic adverse events are papulopustules and xerosis. Less common findings are paronychia, regulatory abnormalities of hair growth, maculopapular rash, mucositis, and postinflammatory hyperpigmentation. Radiation enhances EGFRI rash due to synergistic toxicity. There is a positive correlation between the occurrence and severity of cutaneous adverse effects and tumor response. To date, prophylactic systemic tetracycline and tetracycline class antibiotics have proven to be the most effective treatment regime. K. Chanprapaph, V. Vachiramon, and P.

Comparison the Efficacy of Fluconazole and Terbinafine in Patients with Moderate to Severe Seborrheic Dermatitis Tue, 18 Feb 2014 07:12:16 +0000 http://www.hindawi.com/journals/drp/2014/705402/ Background. Topical agents can be unpleasant due to long-term therapies in patients with moderate to severe seborrheic dermatitis. Systemic antifungal therapy is another alternative in treatment. Aim. This study was conducted to compare the efficacy of oral fluconazole and terbinafine in the treatment of moderate to severe seborrheic dermatitis. Methods. 64 patients with moderate to severe seborrheic dermatitis (SD) were enrolled in a randomized, parallel-group study. One study group took terbinafine 250 mg daily () and the other one fluconazole 300 mg () weekly for four weeks. Seborrheic dermatitis area severity index (SDASI) and the intensity of itching were calculated before, at the end of treatment, and two weeks after treatment. Results. Both drugs significantly reduced the severity of seborrheic dermatitis (). Multivariate linear regression revealed that efficacy of terbinafine is more than fluconazole (, 95% CI (0.63–4.7)). Moreover, each index of SD severity reduced 0.9 times after treatment. (, 95% CI (0.8–1.02)). The itching rate significantly diminished (); however, there was no difference between these two drugs statistically. Conclusions. Both systemic antifungal therapies may reduce the severity index of SD. However, terbinafine showed more reduction in the intensity of the disease. In other words, the more the primary intensity of the disease is, the more its reduction will be. This trial is resgistered with 201102205871N1.

Skin Biopsy in the Context of Dermatological Diagnosis: A Retrospective Cohort Study Thu, 30 Jan 2014 09:24:33 +0000 http://www.hindawi.com/journals/drp/2014/734906/ Background. Skin biopsy is an established method for allying the dermatologist in overcoming the diagnostic dilemmas which occur during consultations. However neither do all skin biopsies produce a conclusive diagnosis nor the dermatologists routinely perform this procedure to every patient they consult. The aim of this study was to investigate the favourable clinical diagnoses set by dermatologists when performing skin biopsy, the diagnoses reached by the dermatopathologists after microscopic examination, and the relationship between them and finally to comment on the instances that skin biopsy fails to fulfill the diagnostic task. Methods. Six thousand eight hundred and sixteen biopsy specimens were reviewed and descriptive statistics were performed. Results. The mean age of the patients was years, the most common site of biopsy was the head and neck (38.3%), the most frequently proposed clinical diagnoses included malignancies (19.28%), and the most prevalent pathological diagnosis was epitheliomas (21.9%). After microscopic examination, a specific histological diagnosis was proposed in 83.29% of the cases and a consensus between clinical and histological diagnoses was observed in 68% of them. Conclusions. Although there are cases that skin biopsy exhibits diagnostic inefficiency, it remains a valuable aid for the dermatology clinical practice.

Type I Interferons: Key Players in Normal Skin and Select Cutaneous Malignancies Sun, 05 Jan 2014 14:01:50 +0000 http://www.hindawi.com/journals/drp/2014/847545/ Interferons (IFNs) are a family of naturally existing glycoproteins known for their antiviral activity and their ability to influence the behavior of normal and transformed cell types. Type I Interferons include IFN-α and IFN-β. Currently, IFN-α has numerous approved antitumor applications, including malignant melanoma, in which IFN-α has been shown to increase relapse free survival. Moreover, IFN-α has been successfully used in the intralesional treatment of cutaneous squamous cell carcinoma (SCC) and basal cell carcinoma (BCC). In spite of these promising clinical results; however, there exists a paucity of knowledge on the precise anti-tumor action of IFN-α/β at the cellular and molecular levels in cutaneous malignancies such as SCC, BCC, and melanoma. This review summarizes current knowledge on the extent to which Type I IFN influences proliferation, apoptosis, angiogenesis, and immune function in normal skin, cutaneous SCC, BCC, and melanoma.

Health-Care Delay in Malignant Melanoma: Various Pathways to Diagnosis and Treatment Sun, 05 Jan 2014 12:27:15 +0000 http://www.hindawi.com/journals/drp/2014/294287/ We aimed to describe and compare patients diagnosed with malignant melanoma (MM), depending on their initial contact with care and with regard to age, sex, and MM type and thickness, and to explore pathways and time intervals (lead times) between clinics from the initial contact to diagnosis and treatment. The sample from northern Sweden was identified via the Swedish melanoma register. Data regarding pathways in health care were retrieved from patient records. In our unselected population of 71 people diagnosed with skin melanoma of SSM and NM types, 75% of patients were primarily treated by primary health-care centres (PHCs). The time interval (delay) from primary excision until registration of the histopathological assessment in the medical records was significantly longer in PHCs than in hospital-based and dermatological clinics (Derm). Thicker tumors were more common in the PHC group. Older patients waited longer times for wide excision. Most MM are excised rapidly at PHCs, but some patients may not be diagnosed and treated in time. Delay of registration of results from histopathological assessments within PHCs seems to be an important issue for future improvement. Exploring shortcomings in MM patients’ clinical pathways is important to improve the quality of care and patient safety.

Effect of Narrow Band Ultraviolet B Therapy versus Methotrexate on Serum Levels of Interleukin-17 and Interleukin-23 in Egyptian Patients with Severe Psoriasis Tue, 31 Dec 2013 13:16:15 +0000 http://www.hindawi.com/journals/drp/2013/618269/ Background. There is raised interest in the involvement of interleukin-(IL-)23/T-helper 17 cells (Th17) axis in the pathogenesis of psoriasis. Objectives. To compare the effect of narrow band ultraviolet B (NB-UVB) and methotrexate (MTX) therapy on serum levels of IL-17 and IL-23 in psoriatic patients. Methods. Thirty patients with severe plaque psoriasis were included: 15 patients received NB-UVB three times weekly (group I) and 15 patients received MTX 0.3 mg/kg per week (group II), both for 8 weeks. Before and after treatment, serum levels of IL-17 and IL-23 were investigated by ELISA technique and psoriasis area and severity index (PASI) was calculated. Results. After treatment, all patients showed a reduction in their PASI score, IL-17 and IL-23 serum levels with a nonsignificant difference between both therapeutic modalities ( value ). A positive correlation was detected between the percent of reduction of IL-17, IL-23 and the percent of reduction of PASI score for patients receiving both treatments. No correlation was found between the percent of reduction of IL-17, IL-23 and duration of disease or age of all patients in this study. Conclusion. Interleukin-17 and IL-23 serum level may serve as a potential biomarker for predicting the prognosis and therapeutic response of NB-UVB or MTX in treating psoriasis.

Polydeoxyribonucleotide Dermal Infiltration in Male Genital Lichen Sclerosus: Adjuvant Effects during Topical Therapy Mon, 30 Dec 2013 18:14:11 +0000 http://www.hindawi.com/journals/drp/2013/654079/ Background. Lichen sclerosus (LS) is an autoimmune inflammatory skin disease that leads to tissue sclerosis. Actually, the first-line treatment consists of local steroid as clobetasol propionate (CP). Polydeoxyribonucleotide (PDRN) has demonstrated anti-inflammatory effects through the reduction of cytokine production and growth stimulation of fibroblast. Objective. To evaluate the efficacy of intradermal administration of PDRN in male patients suffering from genital lichen sclerosus in addition to topical 0.05% CP, as compared to administering 0.05% CP without PDRN injection. Patients/Methods. A group of male patients ( = 28; aged 25 to 65) suffering from LS were observed during topical therapy or subdermal in addition to topical therapy. Disease activity at baseline was evaluated on Investigator’s Global Assessment (IGA) and the Dermatology Life Quality Index (DLQI). We used polydeoxyribonucleotide in a commercial preparation for human use and a topical CP emulsion. Results. After therapy, in all group A patients there has been a regression of most of clinical pathological signs, while there has been a moderate improvement in all group B patients. Conclusions. On site intradermal administration of PDRN, associated with CP 0.05% cream, seemed to be associated with a clinical improvement of lichen sclerosus better than CP used in single therapy.

The Effect of Q-Switched Nd:YAG 1064 nm/532 nm Laser in the Treatment of Onychomycosis In Vivo Sat, 14 Dec 2013 10:56:38 +0000 http://www.hindawi.com/journals/drp/2013/379725/ In this prospective clinical study, the Q-Switched Nd:YAG 1064 nm/532 nm laser (Light Age, Inc., Somerset, NJ, USA) was used on 131 onychomycosis subjects (94 females, 37 males; ages 18 to 68 years). Mycotic cultures were taken and fungus types were detected. The laser protocol included two sessions with a one-month interval. Treatment duration was approximately 15 minutes per session and patients were observed over a 3-month time period. Laser fluencies of 14 J/cm2 were applied at 9 billionths of a second pulse duration and at 5 Hz frequency. Follow-up was performed at 3 months with mycological cultures. Before and after digital photographs were taken. Adverse effects were recorded and all participants completed “self-evaluation questionnaires” rating their level of satisfaction. All subjects were well satisfied with the treatments, there were no noticeable side effects, and no significant differences were found treating men versus women. At the 3-month follow-up 95.42% of the patients were laboratory mycologically cured of fungal infection. This clinical study demonstrates that fungal nail infections can be effectively and safely treated with Q-Switched Nd:YAG 1064 nm/532 nm laser. It can also be combined with systemic oral antifungals providing more limited treatment time.

Evaluating of Life Quality in Patients with Acne Vulgaris Using Generic and Specific Questionnaires Mon, 25 Nov 2013 09:51:23 +0000 http://www.hindawi.com/journals/drp/2013/108624/ Background. Acne vulgaris is a common skin disease that can adversely affect the quality of life of patients. Objective. The aim of this study was to determine the quality of life in patients with acne vulgaris. Methods. This study was carried out on 70 patients with acne vulgaris (28 males, 42 females). All the patients filled out two Persian versions of questionnaires: short form 36 (SF-36) and Dermatology Life Quality Index (DLQI). The obtained data were analyzed by using SPSS software (version 17). Results. The scores for physical functioning, social functioning, and bodily pain domains in patients were over 70%, but the scores for role physical, general health, vitality, role emotional, and mental health in patients were under 70%. Scores on the DLQI in patients with acne vulgaris ranged from 0 to 22 (mean ± SD, 8.18 ± 4.83). After comparing mean score of DLQI with respect to gender and age, it was found that the difference between the two groups was not statistically significant. Conclusion. Acne vulgaris has a significant effect on the quality of life. There was not any significant gender or age related difference in QOL.

Efficacy of Onabotulinum Toxin A (Botox) versus Abobotulinum Toxin A (Dysport) Using a Conversion Factor (1 : 2.5) in Treatment of Primary Palmar Hyperhidrosis Tue, 22 Oct 2013 18:40:55 +0000 http://www.hindawi.com/journals/drp/2013/686329/ Background. Two preparations of botulinum A toxin (BTX-A) are commercially available for the treatment of palmar hyperhidrosis (PPH): Botox (Allergan; 100 U/vial) and Dysport (Ipsen Limited; 500 U/vial), which are not bioequivalent. Results regarding an appropriate conversion factor between them are controversial. Objectives. This paper aims to compare the efficacy of Botox and Dysport in PPH using a conversion factor of 1 : 2.5. Methods. Eight patients with severe PPH received intradermal injections of Botox in one palm and Dysport in the other in the same session. Clinical assessment was performed at baseline and posttreatment for 8 months using Minor’s iodine starch test, Hyperhidrosis Disease Severity Scale (HDSS), and Dermatology Life Quality Index (DLQI) test. Results. At 3 weeks, a significant decrease in sweating for both preparations was noted which was more pronounced with Dysport compared with Botox. At 8 weeks, this difference turned insignificant. Continued evaluation showed similar improvement in both palms with a nonsignificant difference. Patients with longer disease duration were more liable to relapse. Conclusion. The efficacy and safety of Botox and Dysport injections were similar using a conversion factor of 1 : 2.5. There was a trend towards a more rapid action after Dysport treatment but without significant importance.

Effect of Capacitive Radiofrequency on the Fibrosis of Patients with Cellulite Thu, 10 Oct 2013 08:53:16 +0000 http://www.hindawi.com/journals/drp/2013/715829/ Background. Cellulite is a type of lipodystrophy that develops primarily from an alteration in blood circulation or of the lymphatic system that causes structural changes in subcutaneous adipose tissue, collagen, and adjacent proteoglycans. The radiofrequency devices used for cutaneous applications have shown different physiological treatment effects, but there is controversy about the suitable parameters for this type of treatment. Objectives. The aim of this study was to evaluate the effects of low-temperature radiofrequency to confirm the thinning of the collagen tissue and interlobular septa and consequent improvement of cellulite. Methods. A sample of eight women was used to collect ultrasonographic data with a 12 MHz probe that measured collagen fiber thickness. The Vip Electromedicina (Argentina) device, frequency of 0.55 MHz and active electrode 3.5 cm in diameter (area = 9.61 cm2), was applied to a 10 cm2 region of the gluteal region for 2 minutes per area of active electrode, during 10 biweekly sessions. Results. The Wilcoxon matched paired test was applied using GraphPad InStat 3.01 for Win95-NT software. Pre- and posttreatment mean collagen fiber thickness showed a 24.66% reduction from 1.01 to 0.67 mm. Statistical analysis using the Wilcoxon matched paired test obtained a significant two-tailed P value of 0.0391. Conclusion. It was concluded that the use of more comfortable temperatures favored a reduction in fibrous septum thickness and consequent cellulite improvement, evidenced by the lower degree of severity and decrease in interlobular septal thickness.

Skin Cancer Knowledge, Beliefs, Self-Efficacy, and Preventative Behaviors among North Mississippi Landscapers Mon, 07 Oct 2013 08:27:26 +0000 http://www.hindawi.com/journals/drp/2013/496913/ There are slightly over one million workers in the landscape service industry in the US. These workers have potential for high levels of solar ultraviolet radiation exposure, increasing their risk of skin cancer. A cross-sectional sample of 109 landscapers completed a self-administered questionnaire based on Health Belief Model (HBM). The participants correctly answered 67.1% of the knowledge questions, 69.7% believed they were more likely than the average person to get skin cancer, and 87.2% perceived skin cancer as a severe disease. Participants believed that the use of wide-brimmed hats, long sleeved shirts/long pants, and sunscreen was beneficial but reported low usage of these and other sun protective strategies. The primary barriers to using sun protection were “I forget to wear it” and “it is too hot to wear.” Of the HBM variables, perceived benefits outweighing perceived barrier (, ) and self-efficacy (, ) were correlated with sun protection behaviors. The reasons for absence of the relationship between perceived skin cancer threat and sun protection behaviors could be lack of skin cancer knowledge and low rate of personal skin cancer history.

Evaluation of the Quantitative and Qualitative Alterations in the Fatty Acid Contents of the Sebum of Patients with Inflammatory Acne during Treatment with Systemic Lymecycline and/or Oral Fatty Acid Supplementation Thu, 26 Sep 2013 18:12:03 +0000 http://www.hindawi.com/journals/drp/2013/120475/ Background. Acne is a dermatosis that involves an altered sebum pattern. Objectives. (1) To evaluate if a treatment based on antibiotics (lymecycline) can alter fatty acids contents of the sebum of patients with acne; (2) to evaluate if oral supplementation of fatty acids can interfere with fatty acids contents of the sebum of patients with acne; (3) to evaluate if there is any interaction in fatty acids contents of the sebum of patients with acne when they use both antibiotics and oral supplementation of fatty acids. Methods. Forty-five male volunteers with inflammatory acne vulgaris were treated with 300 mg of lymecycline per day, with 540 mg of -linolenic acid, 1,200 mg of linoleic acid, and 510 mg of oleic acid per day, or with both regimens for 90 days. Every 30 days, a sample of sebum from the forehead was collected for fatty acids’ chromatographic analysis. Results. Twelve fatty acids studied exhibited some kind of pattern changes during the study: C12:0, C14:0, C15:0, C16:1, C18:0, C18:1n9c+C18:1n9t, C18:2n6t, C18:3n6, C18:3n3, C20:1, C22:0, and C24:0. Conclusions. The daily administration of lymecycline and/or specific fatty acids may slightly influence some fatty acids levels present in the sebum of patients with inflammatory acne vulgaris.

Chronic Urticaria: Indian Context—Challenges and Treatment Options Tue, 24 Sep 2013 10:46:32 +0000 http://www.hindawi.com/journals/drp/2013/651737/ Urticaria is a common condition that occurs in both children and adults. Most cases have no specific allergic trigger and the aetiology of urticaria remains idiopathic and occasionally spontaneous in nature. Inappropriate advice such as avoidance of foods (milk, egg, prawn, and brinjal) is common place in certain sections of India mostly by nonspecialists that should not be routinely recommended. It is important to look for physical urticarias such as pressure urticaria in chronic cases, which may be present either alone or in combination with other causes. Autoimmune causes for chronic urticaria have been found to play an important role in a significant proportion of patients. Long-acting nonsedating antihistamines at higher than the standard doses is safe and effective. Quality of life is affected adversely in patients with chronic symptomatic urticaria and some may require multidisciplinary management.

Clinical and Capillaroscopic Modifications of the Psoriatic Plaque during Therapy: Observations with Oral Acitretin Mon, 23 Sep 2013 08:46:12 +0000 http://www.hindawi.com/journals/drp/2013/781942/ Psoriasis is considered to be an inflammatory autoimmune disease, where angiogenesis plays an undefined pathogenetic role. The well-known changes of the superficial microvasculature in the psoriatic plaque can be easily assessed in vivo by videocapillaroscopy. In the last years, several studies reported the clinical and capillaroscopic response of the psoriatic plaque during different topical and systemic treatments. In the present work we evaluated the effects of acitretin (0.8 mg/kg/day) on videocapillaroscopic alterations and the clinical response in 11 patients affected by plaque psoriasis at the baseline (T0) and after 4 (T1), 8 (T2), and 12 (T3) weeks. A clinical improvement during the treatment with a complete clinical healing of the plaque in 7 of the 11 patients was observed. The typical “basket-weave” capillaries of the psoriatic lesions showed a reduction of 65.4% in diameter at the end of the study; only 3 patients returned to a normal capillaroscopic pattern. As observed during previous our studies, we found a discrepancy between clinical and capillaroscopic results, with a far greater improvement in the first than in the second. This finding could be in agreement with a secondary role of blood vessels in the pathogenesis and persistence of psoriatic lesions.

The Importance of Trichoscopy in Clinical Practice Thu, 19 Sep 2013 08:55:41 +0000 http://www.hindawi.com/journals/drp/2013/986970/ Trichoscopy corresponds to scalp and hair dermoscopy and has been increasingly used as an aid in the diagnosis, follow-up, and prognosis of hair disorders. Herein, we report selected cases harbouring scalp or hair diseases, in whom trichoscopy proved to be a valuable tool in their management. A review of the recent literature on this hot topic was performed comparing the described patterns with our findings in clinically common conditions, as well as in rare hair shaft abnormalities, where trichoscopy may display pathognomonic features. In our view, trichoscopy represents a valuable link between clinical and histological diagnosis. We detailed some trichoscopic patterns, complemented with our original photographs and our insights into nondescribed patterns.

The Effect of Weight Loss in Obese Patients with Chronic Stable Plaque-Type Psoriasis Wed, 18 Sep 2013 08:17:55 +0000 http://www.hindawi.com/journals/drp/2013/795932/ Background. Chronic plaque psoriasis is frequently associated with obesity. The effect of a low-calorie diet on psoriasis has not been investigated. Objective. The objective was to investigate whether moderate weight loss increases the therapeutic response to topical treatment in obese patients with chronic stable plaque-type psoriasis. Material and Method. A 24-week clinical trial was conducted in 10 patients. The efficacy of a low-calorie diet with topical treatment was compared with baseline in obese patients with chronic stable plaque-type psoriasis. The primary measure of clinical response was the Psoriasis Area and Severity Index at weeks 12 and 24. Results. At week 12, the mean reduction in body weight was 9.6 percent. There was an improvement from baseline of 50 percent or more in the Psoriasis Area and Severity Index in 50 percent of the patients. The responses as measured by improvements in the Psoriasis Area and Severity Index were paralleled by improvements in global assessments by the physician and the patients and in the Dermatology Life Quality Index. Conclusion. Obese patients with chronic stable plaque-type psoriasis increase their response to a low-calorie diet. Lifestyle modifications, including a low-calorie diet, may supplement the pharmacologic treatment of obese psoriasis patients.

Cutis Verticis Gyrata in Men Affected by HIV-Related Lipodystrophy Thu, 12 Sep 2013 11:57:52 +0000 http://www.hindawi.com/journals/drp/2013/941740/ We report the occurrence of cutis verticis gyrata (CVG), a disfiguring dermatological condition, in four patients with HIV-related lipodystrophy (HIVLD). These four patients had abnormal metabolic and hormonal lab values which we compare with metabolic and hormonal perturbations cited in previous HIVLD cohorts. In addition, we describe the sole use of poly-L-lactic acid as a potential treatment for decreasing the appearance of CVG-associated ridges. Keshav Khanijow, Patrick Unemori, Kieron S.

Tamarind Seed Xyloglucans Promote Proliferation and Migration of Human Skin Cells through Internalization via Stimulation of Proproliferative Signal Transduction Pathways Mon, 09 Sep 2013 14:41:13 +0000 http://www.hindawi.com/journals/drp/2013/359756/ Xyloglucans (XGs) of Tamarindus indica L. Fabaceae are used as drug vehicles or as ingredients of cosmetics. Two xyloglucans were extracted from T. indica seed with cold water (TSw) and copper complex precipitation (TSc). Both were analyzed in regard to composition and influence on cell viability, proliferation, cell cycle progression, migration, MAPK phosphorylation, and gene expression of human skin keratinocytes (NHEK and HaCaT) and fibroblasts (NHDF) in vitro. TSw and TSc differed in molecular weight, rhamnose content, and ratios of xylose, arabinose, galactose, and glucose. Both XGs improved keratinocytes and fibroblast proliferation, promoted the cell cycle, and stimulated migration and intracellular enzyme activity of NHDF after endosomal uptake. Only TSw significantly enhanced HaCaT migration and extracellular enzyme activity of NHDF and HaCaT. TSw and TSc predominantly enhanced the phosphorylation of molecules that referred to Erk signaling in NHEK. In NHDF parts of the integrin signaling and SAPK/JNK pathway were affected. Independent of cell type TSw marginally regulated the expression of genes, which referred to membrane proteins, cytoskeleton, cytokine signaling, and ECM as well as to processes of metabolism and transcription. Results show that T. indica xyloglucans promote skin regeneration by a direct influence on cell proliferation and migration. W. Nie and A. M. Deters Copyright © 2013 W. Nie and A. M. Deters.

Psoriasis and Cardiovascular Risk: Assessment by CUORE Project Risk Score in Italian Patients Sun, 08 Sep 2013 15:46:53 +0000 http://www.hindawi.com/journals/drp/2013/389031/ Background. Psoriasis is a common inflammatory and immune-mediated skin disease. There is growing controversy as to whether cardiovascular risk is elevated in psoriasis. A number of studies suggest a high prevalence of cardiovascular risk factors as well as cardiovascular diseases in psoriasis patients. Objective. The objective of this study was to estimate cardiovascular risk score in psoriasis patients and the relation between cardiovascular risk and psoriasis features. Cardiovascular risk was assessed by CUORE project risk score built within the longitudinal study of the Italian CUORE project and suited to populations with a low rate of coronary heart disease. Results. A case-control study in 210 psoriasis outpatients and 111 controls with skin diseases other than psoriasis was performed. CUORE project risk score was higher in patients than controls ( versus , ). Compared to controls, psoriasis patients have higher risk of developing major cardiovascular events. Cardiovascular risk was not related to psoriasis characteristics. Conclusion. Increased focus on identifying cardiovascular risk factors and initiation of preventive lifestyle changes or therapeutic interventions in patients with psoriasis is warranted.

In Vivo Noninvasive Imaging of Healthy Lower Lip Mucosa: A Correlation Study between High-Definition Optical Coherence Tomography, Reflectance Confocal Microscopy, and Histology Tue, 03 Sep 2013 08:06:36 +0000 http://www.hindawi.com/journals/drp/2013/205256/ In recent years, technology has allowed the development of new diagnostic techniques which allow real-time, in vivo, noninvasive evaluation of morphological changes in tissue. This study compares and correlates the images and findings obtained by high-definition optical coherence tomography (HD-OCT) and reflectance confocal microscopy (RCM) with histology in normal healthy oral mucosa. The healthy lip mucosa of ten adult volunteers was imaged with HD-OCT and RCM. Each volunteer was systematically evaluated by RCM starting in the uppermost part of the epithelium down to the lamina propia. Afterwards, volunteers were examined with a commercially available full-field HD-OCT system using both the “slice” and the “en-face” mode. A “punch” biopsy of the lower lip mucosa was obtained and prepared for conventional histology. The architectural overview offered by “slice” mode HD-OCT correlates with histologic findings at low magnification. In the superficial uppermost layers of the epithelium, RCM imaging provided greater cellular detail than histology. As we deepened into the suprabasal layers, the findings are in accordance with physiological cellular differentiation and correlate with the images obtained from conventional histology. The combined use of these two novel non-invasive imaging techniques provides morphological imaging with sufficient resolution and penetration depth, resulting in quasihistological images.

Newer Hemostatic Agents Used in the Practice of Dermatologic Surgery Wed, 07 Aug 2013 14:44:28 +0000 http://www.hindawi.com/journals/drp/2013/279289/ Minor postoperative bleeding is the most common complication of cutaneous surgery. Because of the commonality of this complication, hemostasis is an important concept to address when considering dermatologic procedures. Patients that have a bleeding diathesis, an inherited/acquired coagulopathy, or who are on anticoagulant/antiplatelet medications pose a greater risk for bleeding complications during the postoperative period. Knowledge of these conditions preoperatively is of the utmost importance, allowing for proper preparation and prevention. Also, it is important to be aware of the various hemostatic modalities available, including electrocoagulation, which is among the most effective and widely used techniques. Prompt recognition of hematoma formation and knowledge of postoperative wound care can prevent further complications such as wound dehiscence, infection, or skin-graft necrosis, minimizing poor outcomes.

Botanical Agents for the Treatment of Nonmelanoma Skin Cancer Wed, 24 Jul 2013 11:26:26 +0000 http://www.hindawi.com/journals/drp/2013/837152/ Nonmelanoma skin cancers, including basal cell carcinoma and squamous cell carcinoma, are common neoplasms worldwide and are the most common cancers in the United States. Standard therapy for cutaneous neoplasms typically involves surgical removal. However, there is increasing interest in the use of topical alternatives for the prevention and treatment of nonmelanoma skin cancer, particularly superficial variants. Botanicals are compounds derived from herbs, spices, stems, roots, and other substances of plant origin and may be used in the form of dried or fresh plants, extracted plant material, or specific plant-derived chemicals. They possess multiple properties including antioxidant, anti-inflammatory, and immunomodulatory properties and are, therefore, believed to be possible chemopreventive agents or substances that may suppress or reverse the process of carcinogenesis. Here, we provide a review of botanical agents studied for the treatment and prevention of nonmelanoma skin cancers. Jillian W. Millsop, Raja K. Sivamani, and Nasim Fazel Copyright © 2013 Jillian W.

Alopecia areata (AA) has a significant impact on the quality of life and social interaction of those suffering from it. Our aim was to assess the impact of AA on the quality of life. Methods. Fifty patients diagnosed with AA seen in the Department of Dermatology of Hedi Chaker University Hospital, between March 2010 and July 2010, were included. Quality of life was measured by SF 36; severity of AA was measured by SALT. Results. Eighty percent had patchy alopecia with less than 50% involvement, 12% had patchy alopecia with 50–99% involvement, and 8% had alopecia totalis. Compared with the general population, AA patients presented a significantly altered quality of life, found in the global score and in five subscores of the SF-36: mental health, role emotional, social functioning, vitality, and general health. Gender, age, marital status, and severity of alopecia areata had a significant influence on patients’ quality of life. Conclusions. This study indicates that patients with AA experience a poor quality of life, which impacts their overall health. We suggest screening for psychiatric distress. Studies of interventions such as counseling, psychoeducation, and psychotherapeutic interventions to reduce the impact of the disease may be warranted.

Autologous Serum Skin Test versus Autologous Plasma Skin Test in Patients with Chronic Spontaneous Urticaria Tue, 09 Jul 2013 14:31:34 +0000 http://www.hindawi.com/journals/drp/2013/267278/ Previous studies indicate that 25–45% of chronic urticaria patients have an autoimmune etiology. Autologous serum skin test (ASST) and autologous plasma skin test (APST) are simple tests for diagnosing chronic autoimmune urticaria (CAU). However, there are still some questions about the specificity of these tests. This study consisted of 50 patients with chronic spontaneous urticaria (CSU) and 50 sex- and age-matched healthy individuals aged 18 years, and older. A total of 31 (62%) patients and 5 (10%) control patients had positive ASST; 21 (42%) patients and 3 (6%) control patients had positive APST. Statistically significant differences were noted in ASST and APST positivity between the patient and control groups (ASST ; APST ). Thirteen (26%) patients and 5 (10%) control patients had antithyroglobulin antibodies or antithyroid peroxidase antibody positivity. No statistically significant differences were noted in thyroid autoantibodies between the patient and control groups (anti-TG ; anti-TPO ). We consider that the ASST and APST can both be used as in vivo tests for the assessment of autoimmunity in the etiology of CSU and that thyroid autoantibodies should be checked even when thyroid function tests reveal normal results in patients with CSU.

Skin Disorders among Elder Patients in a Referral Center in Northern Iran (2011) Mon, 08 Jul 2013 09:17:06 +0000 http://www.hindawi.com/journals/drp/2013/193205/ Background. Geriatric health care has become a worldwide concern, but a few statistical studies were carried out about skin diseases in this age group. In this study, we set out to determine the frequency as well as the age and gender distribution of dermatological diseases in geriatric patients. Materials and Methods. In a cross-sectional study, all patients over 60 years who were accepted to department of dermatology in north of Iran participated in this study. Baseline information and clinical examination were done by a group of dermatologists. Biopsy, Pathological and laboratory methods were used in order to confirm the diagnosis. Results. 440 patients were accepted to the department that 232 patients were male (52.7%). Benign neoplasm was as the common skin disease among patients (65%), followed by erythemo-squamous (35.3%) and precancerous lesions (26.1%). The most common precancerous lesion was actinic keratosis (24.3%). BCC by 8.8% was the most prevalent skin carcinoma. Pruritus was the common problem in other dermatological disease (22%). Conclusion. Skin disorders especially precancerous lesion are among those important health problems in elderly patients in this geographic area. Increasing general awareness about risk factors of these diseases and doing more researches in other regions are highly recommended.

Psoriasis Patients’ Knowledge about the Disease and Treatments Mon, 24 Jun 2013 13:52:40 +0000 http://www.hindawi.com/journals/drp/2013/921737/ Patients’ knowledge about psoriasis and its treatment has been randomly studied previously. The aim of the study is to investigate patients’ knowledge about psoriasis in relation to undergoing patient education in the context of climate therapy (CT). The psoriasis knowledge questionnaire (PKQ) was used in a follow-up pre–post study design of Norwegian patients with psoriasis at the age of 20 years and older undergoing CT at Gran Canaria (Spain). Patients completed the PKQ and provided selected demographic, clinical and health information before (T1), immediately after (T2), and 3 months after (T3) CT. Disease severity was assessed using the psoriasis area and severity index (PASI). 254 psoriasis patients were included (74%). The PKQ score improved significantly from T1 to T2 and T3 ( for both comparisons). Although patient’s knowledge improved, further research should use gold standard designs (experiments) to study the effects of educational interventions in different contexts.

Psoriatic Arthritis and Diabetes: A Population-Based Cross-Sectional Study Mon, 17 Jun 2013 09:34:32 +0000 http://www.hindawi.com/journals/drp/2013/580404/ Background. Diabetes has been associated with psoriasis, but little is known about the association between psoriatic arthritis and diabetes. Methods. Patients diagnosed with psoriatic arthritis by a rheumatologist were compared to age- and sex-matched patients without psoriatic arthritis regarding the prevalence of diabetes in a population-based cross-sectional study using logistic multivariate models. The study was performed utilizing the medical database of Clalit, the largest healthcare provider organization in Israel. Results. The study included 549 patients with psoriatic arthritis ≥21 years and 1,098 patients without psoriatic arthritis. The prevalence of diabetes in patients with psoriatic arthritis was increased as compared to the prevalence in patients without psoriatic arthritis (15.3% versus 10.7%, value = 0.008). The difference was prominent among females (18.7% versus 10.3%, ) but not among males (11.2% in patients with and without psoriatic arthritis, ). In a multivariate analysis, psoriatic arthritis was associated with diabetes among females (OR = 1.60, 95% CI: 1.02–2.52, ) but not among males (OR = 0.71, 95% CI: 0.42–1.22, ). Conclusion. Our study suggests a possible association between psoriatic arthritis and diabetes in women. Women with psoriatic arthritis might be candidates for diabetes screening.

Treatment of Nail Psoriasis: Common Concepts and New Trends Mon, 13 May 2013 08:15:08 +0000 http://www.hindawi.com/journals/drp/2013/180496/ The lifetime incidence of nail involvement in psoriatic patients is estimated to be 80–90%, and the nails can be affected in 10% to 55% of psoriatic patients. Psoriasis may also solely involve the nails, without any other skin findings, in which the treatment can be more challenging. Nail psoriasis may lead to considerable impairment in quality of life due to aesthetic concerns and more importantly limitations in daily activities resulting from the associated pain, which may be overlooked by the physicians. Several topical and systemic treatment modalities, as well as radiation and light systems, have been used in the treatment of nail psoriasis. In the last decade, the introduction of biologic agents and the utilization of laser systems have brought a new insight into the treatment of nail psoriasis. This paper focuses on the recent advances, as well as the conventional methods, in treating nail psoriasis in adults and children, in reference to an extensive literature search. Yasemin Oram and A.
