1.  Hand Eczema 
Indian Journal of Dermatology  2014;59(3):213-224.
Hand eczema is often a chronic, multifactorial disease. It is usually related to occupational or routine household activities. Exact etiology of the disease is difficult to determine. It may become severe enough and disabling to many of patients in course of time. An estimated 2-10% of population is likely to develop hand eczema at some point of time during life. It appears to be the most common occupational skin disease, comprising 9-35% of all occupational diseases and up to 80% or more of all occupational contact dermatitis. So, it becomes important to find the exact etiology and classification of the disease and to use the appropriate preventive and treatment measures. Despite its importance in the dermatological practice, very few Indian studies have been done till date to investigate the epidemiological trends, etiology, and treatment options for hand eczema. In this review, we tried to find the etiology, epidemiology, and available treatment modalities for chronic hand eczema patients.

2.  Caveolin-1 Expression in Different Types of Psoriatic Lesions: Analysis of 66 Cases 
Indian Journal of Dermatology  2014;59(3):225-229.
Background:
Caveolin-1 is a key structural and functional protein. Caveolin-1 is known to modulate multiple signal-transducing pathways involved in cell differentiation and proliferation. Psoriasis is viewed as a multifactorial pathology characterized by keratinocyte hyperproliferation and abnormal cell maturation.
Objectives:
To examine the expression of caveolin-1 in skin biopsies from normal subjects, patients, and subjects with the three respective isoforms of psoriasis (psoriasis vulgaris, localized pustular psoriasis, and erythrodermic psoriasis). The expression level of caveolin-1 was compared among psoriasis vulgaris, localized pustular psoriasis, erythrodermic psoriasis, and normal subjects.
Materials and Methods:
Using immunohistochemical methods, caveolin-1 protein expression was assayed in four groups. An analysis was conducted on skin samples obtained from 22 normal subjects and 28 patients with psoriasis vulgaris, 22 patients with localized pustular psoriasis, and 16 patients with erythrodermic psoriasis. The statistical analysis of the scoring criteria reflecting the level of Caveolin-1 immunostaining between different groups was determined using the Mann–Whitney U-test.
Results:
In the normal skin, intense and consistent caveolin-1 staining was present in 22 cases. The Caveolin-1 protein was significantly reduced and showed very weak or absent staining within the tissues of psoriasis vulgaris, localized pustular psoriasis, and erythrodermic psoriasis (respective P < 0.001). Caveolin-1 protein expression in psoriasis vulgaris was higher than that in localized pustular psoriasis and erythrodermic psoriasis (respective P < 0.05). Caveolin-1 protein expression was no different in localized pustular psoriasis and erythrodermic psoriasis (P > 0.05).
Conclusion:
The finding of this study was consistent with a downregulation of Caveolin-1, which might serve as an etiological factor in the development of psoriasis vulgaris, localized pustular psoriasis, and erythrodermic psoriasis. Further mechanistic investigations are required to prove that Caveolin-1 protein has the potential and may be a novel target for therapy of psoriasis vulgaris, localized pustular psoriasis, and erythrodermic psoriasis.

3.  Apoptosis and Clinical Severity in Patients with Psoriasis and HCV Infection 
Indian Journal of Dermatology  2014;59(3):230-236.
Background:
It has been proposed that hepatitis C virus (HCV) antigens are involved in the pathogenesis of psoriasis and may contribute to severity of the disease. Increased expression of the apoptosis-regulating proteins p53 and tTG and decreased levels of bcl-2 in the keratinocytes of the skin of psoriatic patients have been reported.
Aim:
This study aims to identify the serum levels of apoptosis-regulating proteins in patients with psoriasis and without HCV infection and to study the relation between clinical severity of psoriasis and the presence of HCV infection.
Materials and Methods:
Disease severity was assessed by psoriasis area severity index score (PASI) of 90 patients with psoriasis grouped as mild (n = 30), moderate (n = 30) and severe (n = 30); 20 healthy individuals were used as controls. All groups were subjected for complete history taking, clinical examination, and tests for liver function and HCV infection. The serum levels of apoptosis related proteins: p53, tTG and bcl-2 were estimated by enzyme linked immune sorbent assay (ELISA).
Results:
There was a statistically significant (P < 0.001) correlation between clinical severity of psoriasis and presence of HCV antibodies and HCV-mRNA. In addition, significantly (P < 0.001) raised serum p53 and tTG, and reduced bcl-2 were observed among HCV-positive patients as compared to HCV-negative patients and control patients.
Conclusion:
These results conclude that clinical severity of psoriasis is affected by the presence of HCV antibodies and overexpression of apoptotic related proteins. In addition, altered serum levels of apoptosis-regulating proteins could be useful prognostic markers and therapeutic targets of psoriatic disease.

5.  Severity of Psoriasis Among Adult Males is Associated with Smoking, Not with Alcohol Use 
Indian Journal of Dermatology  2014;59(3):237-240.
Context:
Lifestyle factors such as tobacco smoking and alcohol use can affect the presentation and course of psoriasis. There is a paucity of data on this subject from India.
Aims:
To find out whether increased severity of psoriasis in adult Indian males is associated with tobacco smoking and alcohol use.
Settings and Design:
Cross-sectional study in the Department of Dermatology of a Tertiary Care Teaching Hospital.
Subjects and Methods:
Male patients above 18 years of age attending a psoriasis clinic between March 2007 and May 2009 were studied. Severity of psoriasis (measured using Psoriasis Area and Severity Index – PASI) among smokers and non-smokers was compared. We also studied the correlation between severity of psoriasis and nicotine dependence (measured using Fagerström Test for Nicotine Dependence) and alcohol use disorders (measured using Alcohol Use Disorders Identification Test–AUDIT).
Statistical Analysis:
Z-test, Odd's ratio, Chi-square test, Spearman's correlation coefficient.
Results:
Of a total of 338 patients, 148 were smokers and 173 used to consume alcohol. Mean PASI score of smokers was more than that of non-smokers (Z-test, z = −2.617, P = 0.009). Those with severe psoriasis were more likely to be smokers (χ2 = 5.47, P = 0.02, OR = 1.8, Confidence Interval 1.09-2.962). There was a significant correlation between PASI scores and Fagerström score (Spearman's correlation coefficient = 0.164, P < 0.01). Mean PASI scores of persons who used to consume alcohol and those who did not were comparable.(Z-test, z = −0.458, P = 0.647). There was no association between severity of psoriasis and alcohol consumption.(χ2 = 0.255, P = 0.613, Odds Ratio = 1.14, CI 0.696-1.866). There was no correlation between PASI scores and AUDIT scores (Spearman's correlation coefficient = 0.024, P > 0.05).
Conclusions:
Increased severity of psoriasis among adult males is associated with tobacco smoking, but not with alcohol use.

6.  Predictive Factors for Loco Regional Recurrence and Distant Metastasis Following Primary Surgical Treatment of Cutaneous Melanoma 
Indian Journal of Dermatology  2014;59(3):241-246.
Background:
Cutaneous melanoma (CM) has a high propensity for regional and systemic spread. This is one of the largest series of CM reported from India.
Aims:
To predict factors for loco regional recurrence (LRR) and distant metastasis in patients with CM primarily treated with surgery.
Study Design:
Retrospective analysis of patient database at a tertiary care cancer center with evaluation of factors for LRR and distant metastasis for CM.
Materials and Methods:
Data from 68 patients treated for CM between January 2006 and December 2010 were reviewed. Data recorded included age, sex, symptoms, investigations, treatment given, histopathology, recurrence and follow-up. Patient factors, tumor factors, pathologic variables, and adjuvant treatment were investigated as predictors’ of LRR and distant metastasis.
Results:
Mean age of patients was 54 years. Melanoma was more common in males (44). Tumor thickness > 4 mm was found in 43 patients. Lymph node involvement was found in 43 patients. Adjuvant radiotherapy was given in seven patients. At mean follow-up of 16.5 months, LRR was seen in 34 patients and distant metastasis in 28 patients. LRR and distant metastasis were more commonly found in females, age > 40 years, Clark's level IV and V, Breslow's depth > 4 mm, patients with lymph node involvement and extra-capsular spread.
Conclusion:
The age, sex, site, thickness of lesion, involvement of lymph node, and extra-capsular spread were important factors in predicting LRR and distant metastasis. Distant metastasis was also more commonly found in patients with LRR.

7.  The Spectrum of Cutaneous Infection in Diabetic Patients with Hepatitis C Virus Infection: A Single-Center Study from Egypt 
Indian Journal of Dermatology  2014;59(3):247-251.
Context:
Hepatitis-C virus (HCV) infection and diabetes mellitus (DM) have a significant association with skin disorders. Aims: The aim of this study was to assess the impact of HCV infection on the pattern of cutaneous infections among diabetic patients. Methods and Material: A prospective study included diabetic patients who attended Al-Hussein University hospital, Cairo during the period from 2008 to 2010. Patients were examined for skin infections, and investigated for HCV infection.
Statistical Analysis Used:
SPSS (version 11.5).
Results:
The study included 163 patients (102 males and 61 females) with a mean age of 46.2 ± 4.83 years. Ninety five patients (58.3%) were HCV+ve (group A) while 68 patients (41.8%) were HCV-ve (group B). Skin infections in group A included fungal (48.4%), viral (26.3%), bacterial (22.1%) and parasitic (3.2%) while in group B, the spectrum included bacterial (41.2%), fungal (39.7%), viral (11.7%) and parasitic (7.4%). Onychomycosis was the commonest infection in group A (25.2%) compared with folliculitis in group B (19.1%). Cutaneous infections in HCV+ patients were more characterized by increased severity, aggressive course, resistance to treatment and rapid relapse.
Conclusions:
HCV infection has a significant impact in increasing and changing the spectrum of skin infections in diabetic patients. Severe and resistant infections in diabetics could be an important sign of HCV infection.

8.  Aeroallergen Patch Testing in Patients of Suspected Contact Dermatitis 
Indian Journal of Dermatology  2014;59(3):252-256.
Background:
Aeroallergens are airborne substances present in the environment with the potential to trigger an allergic reaction in the respiratory tract, mucosae, or skin of susceptible individuals. The relevance of aeroallergens in the pathogenesis of atopic dermatitis has been reported by many investigators. However, very few studies have been conducted to investigate their role in the production of allergic contact dermatitis (ACD).
Aims:
To determine the prevalence of aeroallergen patch test positivity in patients of suspected ACD and to study the clinical characteristics of patients testing positive with aeroallergens.
Materials and Methods:
Patients presenting to our department with suspected contact allergy and undergoing patch testing with Indian Standard Series (ISS) between January 2010 and June 2011 were studied. After a detailed history and clinical examination, patients were patch tested with ISS and aeroallergen series. Based on the history and clinical suspicion, patients were additionally patch tested with 15% Parthenium. Prior tape stripping was done in some patients.
Results:
Out of total 114 patients, 26 (22.8%) showed sensitivity to aeroallergen series. Parthenium was the commonest aeroallergen being positive in all 26 patients followed by Xanthium in two. None reacted to other allergens. Although positivity was more in patients with prior tape stripping, the difference was not statistically significant.
Conclusion:
Most common aeroallergen found to be positive in our study was Parthenium hysterophorus. In view of low positivity to other allergens, routine aeroallergen patch testing in patients with suspected contact dermatitis may not be necessary.

9.  Lichen Planus: A Clinical and Immuno-Histological Analysis 
Indian Journal of Dermatology  2014;59(3):257-261.
Background:
Direct immunofluorescence examination is an important technique in the diagnosis of cutaneous inflammatory disorders including lichen planus, especially in clinically and histopathological doubtful cases.
Objective:
To study the diagnostic utility of intensity, number, and subtypes of positive immuno-reactants found in lichen planus.
Materials and Methods:
A detailed analysis of clinical as well as immuno-histological features of lichen planus cases was carried out.
Results:
The male to female ratio was 1:1.1. The largest number of patients was in 31-50 year age group. Itching was the most common presenting symptom. Papular lesions were seen in 53% cases. Remaining had hypertrophic (6), follicular (3) and mucosal (9) variants. Clinico-pathological discrepancies were observed in 3 patients. The characteristic histopathological changes including basal cell vacuolization, band-like lymphocytic infiltrate at dermo-epidermal junction were seen in all the biopsies while Civatte bodies were detected in 29% cases. The overall positive yield of direct immunofluorescence microscopy was 55%. Immune deposits at Civatte bodies and dermo-epidermal junction were detected in 47% and 8% of cases, respectively. Immunoglobulin M was the most common immunoreactant followed by immunoglobulin G.
Conclusions:
There was no correlation found between the number and intensity of Civatte bodies with clinical variants of disease and also between the number of positive immunoreactants and clinical severity of the disease. The frequency, number, and arrangement of Civatte bodies in clusters in the papillary dermis as well as multiple immunoglobulins deposition at the Civatte bodies on direct immunofluorescence of skin biopsies are important features distinguishing lichen planus from other interface dermatitis.

10.  A Clinical and Mycological Study of Dermatophytic Infections 
Indian Journal of Dermatology  2014;59(3):262-267.
Background:
Dermatophytoses refer to superficial fungal infection of keratinized tissues caused by keratinophilic dermatophytes. According to observations worldwide, dermatophytoses are the most common of the superficial fungal infections. It is common in tropics and may present in epidemic proportions in areas with high rates of humidity. Although common, the precise size of the problem defies measurement.
Aims:
The present study was undertaken to assess the clinical profile of dermatophytic infection and to identify the species of fungi that are prevalent in this region.
Materials and Methods:
A total of 100 patients clinically suspected for dermatophytoses were selected for the study. Direct microscopy in 10% potassium hydroxide (KOH) and culture was done in each case.
Results:
Out of 100 patients, the maximum were seen in the age groups of 16-30 years. Tinea corporis was the most common clinical type (44.3%) followed by tinea cruris (38.2%). Overall positivity by culture was 39% and by direct microscopy 96%.
Conclusion:
Trichophyton rubrum was the predominant species isolated (67.5%) in all clinical types followed by Trichophyton mentagrophytes. Culturing the fungus may identify the species, but it is not essential for the diagnosis as it is not a sensitive test.

12.  Dermatological Side Effects of Epidermal Growth Factor Receptor Inhibitors: ‘PRIDE’ Complex 
Indian Journal of Dermatology  2014;59(3):271-274.
Epidermal growth factor receptor (EGFR) inhibitor therapy has become the standard treatment for non-small cell lung cancer and head neck malignancy. This class of drug comprises EGFR inhibitors (erlotinib and gefitinib) and monoclonal antibody (cetuximab). Use of this class of drugs has been associated frequently with dermatological side effects termed as PRIDE complex–Papulopustules and/or paronychia, Regulatory abnormalities of hair growth, Itching, Dryness due to EGFR inhibitors. We hereby report the cutaneous side effects of EGFR inhibitor therapy in 15 patients of lung and head/neck cancer. The major clinical findings being acneiform eruption and severe xerosis of skin. Management of these dermatological adverse effects rarely requires discontinuation of targeted therapy and can be managed symptomatically.

13.  Wolf's Isotopic Response: Report of a Case and Review of Literature 
Indian Journal of Dermatology  2014;59(3):275-282.
“Wolf's isotopic response” refers to the occurrence of a new dermatosis at the site of previously healed dermatosis. A number of factors including viral, neural, vascular, and immunologic factors have been implicated in the causation of this peculiar response but none has been proven conclusively. Here, we report a case where lichen planus developed at the site of dermatofibrosarcoma protruberans that had been previously treated with surgery and radiotherapy. We also put forth a hypothesis on the genesis of isotopic response considering the above mentioned factors.

14.  Allergic Contact Dermatitis (Type IV Hypersensitivity) and Type I Hypersensitivity Following Aromatherapy with Ayurvedic Oils (Dhanwantharam Thailam, Eladi Coconut Oil) Presenting as Generalized Erythema and Pruritus with Flexural Eczema 
Indian Journal of Dermatology  2014;59(3):283-286.
Herbal and Ayurvedic medications, believed to be “mild” and “natural” are usually sought as the first line of treatment before resorting to “stronger” allopathic medication. There are very few reports of adverse reactions to either topical and/or systemic Ayurvedic medications. Massage aromatherapy with ayurvedic oils plays an important role in alleviation of pain, but may cause allergic contact dermatitis. This is the second case report of allergic contact dermatitis to ayurvedic oil.

16.  A Case of Reticulate Acropigmentation of Kitamura: Dowling Degos Disease Overlap with Unusual Clinical Manifestations 
Indian Journal of Dermatology  2014;59(3):290-292.
Reticulate hyperpigmentary disorders are a group of rare genetic pigmentary abnormalities which includes reticulate acropigmentation of Kitamura (RAPK), Dowling-Degos disease (DD), reticulate acropigmentation of Dohi (RAPD), Haber's syndrome, and Galli-Galli disease. A 25-year-old male presented with asymptomatic dark-colored lesions on his hands and feet with light-colored skin lesions involving the trunk since three years. Dermatological examination revealed hyperpigmented macules in a reticulate pattern involving the dorsa of the hands and feet, front and sides of the neck, axillae, periorbital region, and groin. Multiple pits were present over both palms, with breaks in dermatoglyphics. He also had multiple nonacne facial scars predominantly on the nose and malar areas. The patient had overlapping features of RAPK and DDD. In addition, he also had hypopigmented macules and acneiform facial scars. Such an overlap of features of reticulate pigmentation has not been previously reported in the literature.

17.  Acquired Bilateral Nevus of ota-like Macules with Mucosal Involvement: A New Variant of Hori's Nevus 
Indian Journal of Dermatology  2014;59(3):293-296.
Acquired bilateral nevus of Ota-like macules (ABNOM) or Hori's nevus, a rare form of acquired dermal melanocytoses, presents as bilateral facial blue-gray macules without ocular or mucosal involvement. This condition is mostly found in women of Asian descent and usually appears in the fourth or fifth decade of life. Pathogenesis is unknown, though few theories have been proposed. Effective treatment has been found to be achieved with pigment-specific lasers. Herein, we report a case of Hori's nevus with mucosal involvement. A 42-year-old male patient, presented to us with blue-gray discoloration on either side of his face, both eyes, and in the mouth since the age of one year. Histopathological examination showed clusters and singly dispersed pigmented melanocytes within the upper and mid-dermis regions. Special staining of melanocytes using Masson-Fontana stain was positive. Diagnosis of Hori's nevus was made by correlating clinical and histopathological findings. Patient was informed of his treatment options, but refused treatment. A similar case of Hori's nevus with mucosal involvement has not been reported so far.

19.  Myxoinflammatory Fibroblastic Sarcoma: An Uncommon Tumour at an Unusual Site 
Indian Journal of Dermatology  2014;59(3):297-298.
Myxoinflammatory fibroblastic sarcoma is a low grade sarcoma that is composed of a mixed inflammatory infiltrate along with spindled, epithelioid and bizarre appearing cells in a background of hyaline and myxoid zones. Seen affecting the distal extremities commonly, with an equal sex predilection, these tumors are rare and require an extensive immunohistochemical work up for proper diagnosis. They have a tendency to recur.

20.  Varicella Zoster with Erythema Multiforme in a Young Girl: A Rare Association 
Indian Journal of Dermatology  2014;59(3):299-301.
Erythema multiforme (EM) is an acute, self-limited, mucocutaneous disorder regarded as a hypersensitivity reaction which is triggered by various factors like infection, drugs, and food. Infectious agents are considered to be a major cause of EM other than idiopathic cause. A young girl presented with fluid-filled lesions all over the body of 3 days duration with history of similar lesions with fever in her sibling 2 weeks prior to admission. This was followed by large fluid-filled lesions with halo 3 days thereafter over the trunk, extremities suggesting target lesions of EM. The diagnosis was confirmed by cytology and positive serology. Varicella zoster virus (VZV) has rarely been reported as an etiological agent, despite its high incidence in childhood. VZV as an etiology of EM in a young girl has not been reported so far. This case was reported for its rare association of EM and varicella zoster and also for its rare presentation in a young girl.
