Background: Dermoscopy is useful in the diagnosis of basal cell carcinoma (BCC). However, most descriptions of the dermoscopic features of BCCs are in Caucasians (skin types I-III) and there is a paucity of data in dark-skinned Indian patients. Aims: The aim of this study was to describe the various dermoscopic features of BCC in dark-skinned patients from South India and correlate these with the histopathologic subtypes. Methods: A retrospective observational study of biopsy-proven cases of BCC was conducted at a tertiary care center in South India using nonpolarized contact dermoscopy. Results: Sixty BCCs in 35 patients predominantly of skin phototypes IV or V were studied. These included 32 nodular, 27 superficial and 1 infiltrative type of BCC. The most common dermoscopic features noted were maple leaf-like areas (61.7%), blue-white veils (53.4%), ulceration (48.4%) and short fine telangiectases (46.7%). Ulceration, blue-white veils and arborizing vessels were significantly associated with nodular BCCs, while maple leaf-like areas, red-white structureless areas, multiple small erosions and spoke wheel areas were noted with superficial BCCs. Limitations: The limitations of this study include its retrospective nature, the use of only nonpolarized light for examination, the lack of other histopathological variants of BCC as well as the lack of a comparison group. Conclusion: We report a dermoscopic study of BCC in dark-skinned patients from Puducherry, South India. The blue-white veil was observed in half of the patients and was significantly associated with nodular BCCs. The addition of the blue-white veil to the diagnostic criteria for pigmented BCC could improve the diagnostic accuracy of dermoscopy in Indian patients. [ABSTRACT FROM AUTHOR]

The article is a book review of "Dermatitis-A contemporary approach in primary care practice." The book is aimed at general practitioners who struggle with diagnosing and managing eczemas, which make up about 30% of skin diseases. The book covers commonly encountered dermatitis in the Indian context, with each chapter introducing a case scenario and providing information on diagnosis and treatment. The reviewer recommends the book to private practitioners and inexperienced dermatologists, as it addresses the issue of misuse of topical corticosteroids. [Extracted from the article]

Background: Chronic paronychia, earlier considered to be an infection due to Candida, is currently being considered as a dermatitis of the nail fold. Irritant, allergic and protein contact dermatitis are the suggested major pathogenic mechanisms. Hypersensitivity to Candida is more likely to be the etiology, rather than the infection itself. Aims: To assess the clinico-etiological profiles of patients with chronic paronychia and to determine the role of contact sensitization and hypersensitivity to Candida. Methods: All consecutive patients of chronic paronychia attending the dermatology outpatient department (OPD) were assessed for risk factors, number of nails affected, clinical presentation and presence of fungus, patch tested for contact allergy and prick tested for hypersensitivity to Candida allergen. Results: A total of 80 patients of chronic paronychia were recruited into our study. There was female preponderance (66 patients, 82.5%), with the most common group affected being housewives (47 patients, 58.8%). Frequent washing of hands (64 patients, 80%) was the most common risk factor. Fungal culture was positive in 56.1% (41 patients), the predominant species cultured was Candida albicans (15 patients, 36.5%). Patch testing with Indian standard series was positive in 27.1% patients (19 out of 70 patients tested), with nickel being the most common allergen. Prick test with Candida allergen was positive in 47.6% patients (31 out of 65 patients tested). Limitations: Prick test and patch test provide indirect evidence of hypersensitivity, with inherent limitations. Conclusion: Our study shows that chronic paronychia is probably a form of hand dermatitis associated with prolonged wet work, and that there is a higher incidence of contact sensitization and Candida hypersensitivity in these patients.

Background and Objectives: Recently, the concept of "psoriatic march" has come to the fore, in which chronic cutaneous inflammation in psoriasis leads to systemic inflammation which, in conjunction with increased oxidative stress, triggers a cascade of events resulting in increased cardiovascular risk in patients with severe psoriasis. We, therefore, decided to study the levels of some biochemical cardiovascular risk markers: lipid peroxidation (malondialdehyde), lipoprotein (a), lipid indices and atherogenic index, in patients with psoriasis and their association with disease severity. Methods: Fortyfive patients with psoriasis and 45 age and gender-matched healthy controls were included in this cross-sectional study. Disease severity was assessed by the Psoriasis Area Severity Index (PASI). Serum malondialdehyde, lipoprotein (a) and fasting lipid profile were estimated in all study subjects. Lipoprotein ratios were computed using standard formulae. Atherogenic index was calculated as ratio of lipoprotein (a)/high-density lipoprotein. Results: In psoriasis, we observed significantly higher levels of malondialdehyde, total cholesterol, low-density lipoprotein cholesterol, non-high-density lipoprotein cholesterol, lipoprotein (a), lipid ratios, atherogenic index and comprehensive lipid tetrad index, compared to controls. These levels were directly proportional to disease severity. Serum levels of malondialdehyde correlated positively with serum lipoprotein (a), comprehensive lipid tetrad index and atherogenic index. Limitations: Different morphological types of psoriasis were not included and follow-up post-therapy was not done. A larger sample size would have validated the results further. Conclusion: Our results indicate that psoriasis, especially the severe variants, are associated with increased oxidative stress and dyslipidemia, which correlate positively with atherogenic index and hence, an increased cardiovascular risk.

Mongolian spots (MS) are birthmarks that are present at birth and their most common location is sacrococcygeal or lumbar area. Lesions may be single or multiple and usually involve < 5% total body surface area. They are macular and round, oval or irregular in shape. The color varies from blue to greenish, gray, black or a combination of any of the above. The size varies from few to more than 20 centimetres. Pigmentation is most intense at the age of one year and gradually fades thereafter. It is rarely seen after the age of 6 years. Aberrant MS over occiput, temple, mandibular area, shoulders and limbs may be confused with other dermal melanocytoses and bruises secondary to child abuse, thus necessitating documentation at birth. Although regarded as benign, recent data suggest that MS may be associated with inborn errors of metabolism and neurocristopathies. Mongolian spots usually resolve by early childhood and hence no treatment is generally needed if they are located in the sacral area. However, sometimes it may be required for extrasacral lesions for cosmesis. [ABSTRACT FROM AUTHOR]

Background: Intralesional corticosteroids are the treatment of choice for adults with less than 50% of scalp area involvement with alopecia areata. The sensitivity of picking up clinical response to treatment by clinical examination is very variable and has inter individual variation. Aims: To evaluate the efficacy of intralesional triamcinolone acetonide in the treatment of alopecia areata and to use dermoscopy to identify signs of early clinical response and adverse effects. Methods: Seventy patches in 60 patients were injected with steroid at 4 weeks interval and followed up for 24 weeks. Treatment response was evaluated using regrowth scale (RGS). Heine DELTA 20® dermatoscope was used to assess disease activity, response to treatment and side effects. Results: Twenty eight patients responded early and achieved RGS of 4 within 12 weeks and 29 patients responded late and achieved RGS of 4 within 24 weeks of initiating therapy. There were 3 patients who did not achieve RGS of 4 at 24 weeks. Late and incomplete responders showed statistically significant association with family history of alopecia areata (p < 0.0001), presence of recurrent disease (p = 0.0147) and presence of nail changes (p = 0.0007). Dermoscopically, 60 patches demonstrated regrowth of new vellus hair at 4 weeks. Tapering hair disappeared maximally at 4 weeks. At 12 weeks, complete disappearance was seen in tapering hairs, broken hairs and black dots whereas for yellow dots to disappear completely in all patches it took 16 weeks. The adverse effects were observed at an earlier stage using dermoscopy than clinically. Conclusion: Intralesional triamcinolone acetonide is efficacious for treatment of localized patchy alopecia areata. Dermoscopy is very useful to identify signs of early clinical response, adverse effects and markers of disease activity. [ABSTRACT FROM AUTHOR]

There is increasing evidence in support of the interplay of growth hormone (GH), insulin, and insulin-like growth factor-1 (IGF-1) signaling during puberty, which have a causal role in pathogenesis of acne by influencing adrenal and gonadal androgen metabolism. Milk consumption and hyperglycemic diets can induce insulin and IGF-1-mediated PI3K/Akt-activation inducing sebaceous lipogenesis, sebocyte, and keratinocyte proliferation, which can aggravate acne. Occurence of acne as part of various syndromes also provides evidence in favor of correlation between IGF-1 and acne. [ABSTRACT FROM AUTHOR]

Background: Periorbital dermatoses are very common dermatological disorders which pose a diagnostic and therapeutic challenge for the treating dermatologist due to the similarity of symptoms in this area. Aims: To study the spectrum of periorbital dermatoses and to assess the association of systemic diseases with periorbital dermatoses. Methods: This was a hospital based descriptive study done on 250 consecutive patients irrespective of their age and sex who attended the Dermatology out patient department (OPD), with dermatological conditions pertaining to the periorbital area over a period of 2 years from October 2010 to September 2012. Results: The most common dermatological conditions seen in the periorbital region were benign and malignant skin tumors observed in 63 (25.2%) cases, followed by the disorders of pigmentation in 51 (20.4%) and eczema in 44 cases (17.6%), infections in 33 (13.2%) cases and nevoid conditions in 26 (10.4%) cases. Certain periorbital dermatoses were significantly more in females than in males in the present study like skin tags, connective tissue diseases, and periorbital melanosis (POM). Some periorbital dermatoses were significantly more common in older age group such as seborrheic keratoses, skin tags and airborne contact dermatitis whereas infections, syringomas, allergic contact dermatitis and atopic dermatitis were more prevalent in younger age group. Syringomas and POM were more common in middle-aged women. Conclusions: The most common dermatological condition seen in the periorbital region in this study are benign skin tumors (keratosis and skin tags), followed by the disorders of pigmentation and eczema, infections and nevoid conditions.

The authors reflect on the concept of impact factor (IF) which has become a common parlance in the scientific community. They outline the factors relevant on the calculation of IF, including the coverage and language preferences of the Science Citation Index (SCI) database, negative citations and publication lag. The authors further claim the need to realize that IF is a misleading tool in assessing the quality of the paper and the researcher as well.

Depigmentation therapy in vitiligo is an option in those with extensive vitiligo who have failed to respond to medical therapy and have obvious cosmetic disfigurement due to intervening patchy pigmented areas. Various aspects of this therapy such as the cost, treatment time, course, permanency of depigmentation, side effects, and the possibility of repigmentation should first be discussed with the patient. At present, there is no ideal depigmenting therapy available, but many agents in the market have been in use for many years. Monobenzyl ether of hydroquinone (MBEH) is the mainstay and Food and Drug Administration (FDA) approved in USA but takes many months to depigment and is associated with local side effects and risk of repigmentation. Other agents which are also used are 4-methoxy phenol and 88% phenol. Physical therapies for depigmentation include Q-switched ruby and alexandrite lasers and cryotherapy. Second-line agents which can be explored for depigmentation include imatinib mesylate, imiquimod, and diphencyprone. Many possible experimental agents are being explored like various phenol derivatives, melanoma vaccines, interferon gamma, busulfan, etc. A major lacuna still exists in this area and a lot more research is desirable to give satisfactory cosmesis to these patients with extensive vitiligo.

The authors reflect on how to monitor methotrexate hepatotoxicity in patients with psoriasis. The authors say that the adverse effects of taking methotrexate are gastrointestinal symptoms and abnormal liver function tests (LFTs). They mention that methotrexate can be administered effectively if the patient is under regular monitoring on the progression of liver fibrosis and cirrhosis. They suggest that procollagen III (PIIINP) levels can be a useful alternative in monitoring methotrexate.

Congenital melanocytic nevus (CMN) may rarely regress which may also be associated with a halo or vitiligo. We describe a 10-year-old girl who presented with CMN on the left leg since birth, which recently started to regress spontaneously with associated depigmentation in the lesion and at a distant site. Dermoscopy performed at different sites of the regressing lesion demonstrated loss of epidermal pigments first followed by loss of dermal pigments. Histopathology and Masson-Fontana stain demonstrated lymphocytic infiltration and loss of pigment production in the regressing area. Immunohistochemistry staining (S100 and HMB- 45), however, showed that nevus cells were present in the regressing areas. [ABSTRACT FROM AUTHOR]

Background: Even though seborrheic keratoses (SK) have been well characterized clinically and histopathologically, data regarding clinical and dermoscopic correlation of different types of SK are inadequate. Aims: We carried out a study to establish any correlation between the clinical and dermoscopic appearance of SK and its variants. Methods: This was a descriptive study conducted in the Department of Dermatology, a tertiary care institute, from August 2008 to June 2010. Patients with SK were evaluated with respect to age, sex, age of onset, duration, site of lesions, number of lesions, and morphology. Dermoscopy was performed in all cases. Results: A total of 250 cases of SK were recruited. A male-to-female ratio was 1:1.04. The most common age group affected by SK was 60 years and above (40%). The most common clinical variant was common seborrheic keratosis (CSK) (60%). Comedo-like openings (CL) (80%), fissures and ridges (FR) (52%), and sharp demarcation (SD) (83%) were consistent finding on dermoscopy in CSK. Dermatosis papulosa nigra (DPN) and pedunculated seborrheic keratoses (PSK) had characteristic CL and FR in both of them. Fingerprint (FP) (55%) and network-like (NL) (88%) structures were commonly seen in flat SK. Stucco keratoses demonstrated SD (100%) and NL structures (100%). Conclusions: The most common clinical variant of SK was CSK, followed by DPN, PSK, Flat SK, and stucco keratoses. Dermoscopic findings were consistent with those described in the literature.

Background: Lichen simplex chronicus (LSC) of the anogenital region, is a benign, extremely uncomfortable disease. Aims: As very little is known about the cause of anogenital LSC (AGLSC), we undertook this study to determine various clinico-etiological factors involved in it and to assess the frequency of AGLSC. Methods: This was a descriptive study, including 105 patients with AGLSC, who attended the Dermatology clinic in our institute from September 2007 to June 2009. Detailed history, physical examination, and relevant investigations were done. The collected data were tabulated and analyzed. Results: The frequency of AGLSC among patients presenting with anogenital pruritus was 2.54%. Primary AGLSC was more common than secondary AGLSC (69.5% vs. 30.5%). AGLSC manifested more commonly in males than in females (56.2% vs. 43.8%). The mean duration of the disease was 30.6 months. The common triggering factors for itching were sweating (41.9%), rubbing of thighs while walking for long distances (9.5%), and mental stress (5.7%). Pruritus of AGLSC was related to the intake of various food items in 37.1% of patients. In males, scrotum was the predominant site involved (89.8%), whereas in females, labia majora was the predominant site involved (78.2%). Nearly one-third of cases (30.5%) of AGLSC had some other dermatoses in the anogenital region. Conclusions: Though psychological factors are thought to play an important role in disease causation and perpetuation among AGLSC patients, their significance could not be ascertained by us.

Drug hypersensitivity syndrome (DHS) is an adverse drug reaction commonly associated with the aromatic antiepileptic drugs (AEDs), viz., phenytoin (PHT), carbamazepine (CBZ), phenobarbital (PB), lamotrigine, primidone, etc. It can also be caused by other drugs, such as sulfonamides, dapsone, minocycline, gold derivatives, cyclosporine, captopril, diltiazem, terbinafine, azathioprine and allopurinol. Diagnosis of DHS may be difficult because of the variety of clinical and laboratory abnormalities and manifestations and because the syndrome may mimic infectious, neoplastic or collagen vascular disorders. The risk for developing hypersensitivity within 60 days of the first or second prescription in new users of PHT or CBZ was estimated to be 2.3-4.5 per 10,000 and 1-4.1 per 10,000, respectively. The syndrome is defined by the fever, skin rash, lymphadenopathy and internal organ involvement within the first 2-8 weeks after initiation of therapy. Internal manifestations include, among others, agranulocytosis, hepatitis, nephritis and myositis. Insufficient detoxification may lead to cell death or contribute to the formation of antigen that triggers an immune reaction. Crossreactivity among PHT, CBZ and PB is as high as 70%-80%. Management mainly includes immediate withdrawal of the culprit drug, symptomatic treatment and systemic steroids or immunoglobulins. [ABSTRACT FROM AUTHOR]

Background: Psoriatic nail changes predispose to onychomycosis because it becomes easier for fungi to penetrate an already compromised nail plate. Moreover, some of the psoriatic nail changes closely resemble onychomycosis. Aim: To investigate cases of nail psoriasis for any evidence of onychomycosis. Methods: Seventy-two patients with psoriasis were included in the study. The patients were selected from the psoriasis clinic and dermatology in-patient ward. Direct microscopic examination with 20% KOH and culture were carried out in all patients showing psoriatic nail changes. Histopathological examination with Periodic Acid-Schiff (PAS) stain was done in cases negative by KOH examination and culture. Results: Nail changes were seen in 66.66% (48/72) of psoriasis patients. The most common fingernail changes observed were pitting, onycholysis and subungual hyperkeratosis, and the most common toenail changes were onycholysis and subungual hyperkeratosis. Nail changes were significantly more common in males. The duration of skin lesions of psoriasis and Psoriasis Area Severity Index scores were significantly higher in patients with nail changes. Out of 48 patients with psoriatic nail change, 23 (47.91%) had investigative evidence of onychomycosis. The fungal isolates on culture were non-dermatophytic molds in nine patients (18.75%) and yeast like fungi also in nine patients (18.75%). Conclusion: Coexistent onychomycosis in psoriatic nails does occur. [ABSTRACT FROM AUTHOR]

Background: Melasma is a common cause of facial hyperpigmentation with significant cosmetic deformity. Many modalities of treatment are available, but none is satisfactory. Aim: This study was designed to compare the therapeutic response of melasma in Indian women to glycolic acid (GA 20-35%) versus trichloroacetic acid (TCA 10-20%) for chemical peeling. Methods: Forty nonpregnant female patients with a minimum melasma area and severity index (MASI) of 10 were recruited in the study. After a detailed history and clinical examination under natural light, MASI was calculated and color photographs were taken of all the patients. The patients were advised to carry out a prepeel program of daily application of 12% GA cream or 0.1% tretinoin at night for 2 weeks. They were then treated with graded concentrations of 20-35% GA facial peel every 15 days in GA group and 10-20% TCA in the second group. Results: Objective response to treatment evaluated by reduction in MASI scoring after 12 weeks was by 79% reduction (from 26.6 to 5.6) in GA group and by 73% reduction in TCA group (from 29.1 to 8.2) but this difference was not significant. Patients with epidermal-type melasma showed a better response to treatment than those with mixed-type melasma (P < 0.05). Subjective response, as graded by the patient, showed good or very good response in 75% in GA group and 65% in TCA group. No relation of treatment response to age and duration of melasma could be established in this study. Conclusions: A prepeel program of daily application of 12% GA cream at night for 2 weeks, followed by graded increase in GA and TCA concentrations proved to be an equally effective treatment modality for epidermal and mixed melasma. There are hardly any major side effects, and regular use of sunscreens prevents chances of postpeel hyperpigmentation. GA peel is associated with fewer side effects than TCA and has the added advantage of facial rejuvenation. [ABSTRACT FROM AUTHOR]

Diet has an important role to play in many skin disorders, and dermatologists are frequently faced with the difficulty of separating myth from fact when it comes to dietary advice for their patients. Patients in India are often anxious about what foods to consume, and what to avoid, in the hope that, no matter how impractical or difficult this may be, following this dictum will cure their disease. There are certain disorders where one or more components in food are central to the pathogenesis, e.g. dermatitis herpetiformis, wherein dietary restrictions constitute the cornerstone of treatment. A brief list, although not comprehensive, of other disorders where diet may have a role to play includes atopic dermatitis, acne vulgaris, psoriasis vulgaris, pemphigus, urticaria, pruritus, allergic contact dermatitis, fish odor syndrome, toxic oil syndrome, fixed drug eruption, genetic and metabolic disorders (phenylketonuria, tyrosinemia, homocystinuria, galactosemia, Refsum's disease, G6PD deficiency, xanthomas, gout and porphyria), nutritional deficiency disorders (kwashiorkar, marasmus, phrynoderma, pellagra, scurvy, acrodermatitis enteropathica, carotenemia and lycopenemia) and miscellaneous disorders such as vitiligo, aphthous ulcers, cutaneous vasculitis and telogen effluvium. From a practical point of view, it will be useful for the dermatologist to keep some dietary information handy to deal with the occasional patient who does not seem to respond in spite of the best, scientific and evidence-based therapy.

Management of genital herpes is complex. Apart from using the standard antivirals, an ideal management protocol also needs to address various aspects of the disease, including the psychological morbidity. Oral acyclovir, valacyclovir or famciclovir are recommended for routine use. Long-term suppressive therapy is effective in reducing the number of recurrences and the risk of transmission to others. Severe or disseminated disease may require intravenous therapy. Resistant cases are managed with foscarnet or cidofovir. Genital herpes in human immunodeficiency virus-infected individuals usually needs a longer duration of antiviral therapy along with continuation of highly active anti retroviral therapy (HAART). Genital herpes in late pregnancy increases the risk of neonatal herpes. Antiviral therapy and/or cesarean delivery are indicated depending on the clinical circumstance. Acyclovir appears to be safe in pregnancy. But, there is limited data regarding the use of valacyclovir and famciclovir in pregnancy. Neonatal herpes requires a higher dose of acyclovir given intravenously for a longer duration. Management of the sex partner, counseling and prevention advice are equally important in appropriate management of genital herpes. Vaccines till date have been marginally effective. Helicase-primase inhibitors, needle-free mucosal vaccine and a new microbicide product named VivaGel may become promising treatment options in the future. [ABSTRACT FROM AUTHOR]

Background: Pemphigus disorders are a group of serious and potentially life-threatening diseases affecting skin and/or mucus membranes. Dexamethasone-cyclophosphamide pulse (DCP) therapy has shown promising results in the management of these diseases. Aims: The objective of the study was to assess the outcome of DCP therapy in pemphigus. Methods: Pemphigus patients who had been treated with DCP therapy from 2001 to 2008 were prospectively and retrospectively analyzed. Results: A total of 65 pemphigus patients were enrolled. Male to female ratio was 1 : 1.82. Mean age of patients was 44.65 ± 11.85 years with a range of 14 to 73 years. Thirty two patients completed phase I, of which 28 (9 in phase II, 7 in phase III and 12 in phase III) were maintaining remission and four patients relapsed. Relapse was observed only in patients who discontinued or took irregular treatment. Six patients were declared cured of disease. Five patients died during phase I. Dexamethasone-cyclophosphamide pulse therapy is not absolutely free from adverse effects. Most of the immediate side effects were expected, tolerable and did not pose any problem in continuing treatment. There was a slight increased incidence of weight gain, hypertension, diabetes mellitus, cataract and Cushingoid habitus, since most of our patients also received additional daily oral steroids. Also, there was a high incidence of secondary pyogenic infections of skin lesions and oral candidiasis during phase I. Staphylococcus aureus was the commonest bacteria isolated from the pus of skin lesions. Most of the alterations in laboratory parameters were transitory or correctable, and did not pose a problem in continuing therapy. Conclusions: DCP therapy was found to be effective in inducing and maintaining remission in pemphigus, provided the patients receive regular and complete treatment. [ABSTRACT FROM AUTHOR]

Background: Acne vulgaris is believed to be the most common disease of the skin. There is no Indian study on the profile of acne vulgaris, markers of severe forms of acne vulgaris and a possible correlation between acne vulgaris and markers of androgenicity in females. Aim: To study the profile of acne vulgaris, its seasonal variation, relationship with smoking and possible correlation between acne vulgaris and markers of androgenicity in females. Methods: The study was conducted between August 2006 and June 2008. All patients with acne vulgaris who consented to participate in the study were included. The parameters evaluated included age, gender, age of onset, duration of lesions, site of lesions, grade, relation with menstrual cycle, markers of androgenicity, number of acne lesions such as comedones, papules pustules and nodules, number and site of post-acne scarring, post-acne hyperpigmentation, seasonal variation and history of smoking. Results: A total of 309 patients with acne vulgaris were included in the study. The frequency of acne vulgaris in our study was 1.068%. Mean age of the study group was 19.78 years. Male to female ratio was 1.25:1. The most common age group involved was 16 to 20 years (59.8%). Mean age of onset was 15.97 years. Face was involved in all the patients, followed by back (28.2%), chest (20.1%), neck (9.4%) and arms (10%). In the older age groups, women were more likely to report having acne vulgaris than men (P = 0.01). The closed comedones outnumbered open comedones by a factor of 4.9:1. A total of 186 patients (60.2%) had grade 1 acne vulgaris, 85 (27.5%) had grade 2 acne, 8 (2.6%) had grade 3 acne and 30 (9.7%) had grade 4 acne vulgaris. There was a higher incidence of scarring (39.5%) and post-acne hyperpigmentation (24.6%) in our study. In female patients, 57.7% had premenstrual flare and 12.4% had cutaneous markers of androgenicity. There was no association between severity of acne vulgaris and other markers of androgenicity (P = 0.108). Seborrheic dermatitis (21.35%) was the most common disease associated. Seasonal variation was observed only in 80 patients (25.9%); 71 patients (23%) exacerbated in summer and 9 patients (2.9%) in winter. Smokers had more severe grade of acne vulgaris compared to nonsmokers (P = 0.001). Conclusion: This study brings out the clinical profile of acne vulgaris in a tertiary care hospital in South India.

This article takes a critical look at the pros and cons of human papillomavirus (HPV) vaccines. There is enough evidence to suggest that the prophylactic vaccines are efficacious in preventing various benign and malignant conditions (including cervical cancers) caused by HPV. Even though the vaccine is costly, hypothetical analysis has shown that HPV vaccination will be cost effective in the long run. Therapeutic HPV vaccines used to treat established disease are still undergoing evaluation in clinical studies, and results seem to be encouraging. Although several countries have started mandatory vaccination programs with the prophylactic HPV vaccines, conservatives have voiced concerns regarding the moral impact of such vaccination programs.

The article discusses the scoring systems that dermatologists used to measure acne vulgaris based on clinical examination and photographic documentation. Since the acne lesions may vary in number during the natural course of the disease, it notes that various measurements have been developed in order to assess the clinical severity of acne vulgaris. It stresses that an ideal grading system should be accurate and reproducible, and should be capable of documentation for future verification.

The article offers information on the history of the Indian Association of Dermatologists, Venereologists and Leprologists (IADVL) in India. The association was established on January 28, 1973. U. B. Narayan Rao began the publication "Indian Journal of Venereology" in 1935. He was the brainchild of the creation of the association of dermatologists and venereologists. The association was inaugurated by Home and Revenue Minister Shri Morarji M. Desai.

Leprosy is unique in terms of the nature of the causative organism (Mycobacterium leprae), the chronicity of the disease, its prolonged treatment and the definitions of "cure" and "relapse." The principal mode of assessing the efficacy of therapeutic regimens in leprosy is the "relapse rate." There are wide variations in estimates of relapse rates after the World Health Organization (WHO) multidrug therapy in different regions. The important predisposing factors for relapse include the presence of "persister" bacilli, monotherapy, inadequate/irregular therapy, presence of multiple skin lesions/thickened nerves and lepromin negativity. The conventional methods of confirming activity or relapse in an infectious disease (demonstration and/or culture of the etiologic agent) have limited utility in leprosy because of the difficulty in demonstrating bacilli in paucibacillary (PB) cases and absence of a method of in vitro cultivation of M. leprae. Bacteriological parameters are useful in multibacillary (MB) leprosy, whereas in PB leprosy, the criteria for relapse depend primarily on clinical features. Although there are no widely available serologic tests for leprosy other than in a research setting, various immunological tests may be useful for monitoring patients on chemotherapy as well as for confirming suspected cases of relapse. The main differential diagnoses for relapse are reversal reactions, erythema nodosum leprosum and reactivation/ resistance/reinfection. The most reliable criteria for making an accurate diagnosis of relapse include clinical, bacteriological and therapeutic criteria. Additional ones that may be used, depending on the setting, are histopathological and serologic criteria. Relapsed cases of leprosy should be identified and put back on chemotherapy as soon as possible to prevent further disability and transmission of infection. Factors that should be considered in choosing an appropriate regimen are the type of leprosy (PB or MB), previous treatment and drug resistance. Occasionally, clinicians may need to use their judgement to modify the standard WHO treatment regimens according to the scenario in each patient. [ABSTRACT FROM AUTHOR]

The article discusses the emergence of dermatology in India. Dermatology as a specialty came into prominence only in the twentieth century, although skin diseases like leprosy, viral fevers like measles and chicken pox, psoriasis, and vitiligo were recognized long back. The incidence and etiology of endemic skin diseases in the country is reviewed. The start of postrgraduate teaching in the specialty is included.

Rhinosporidiosis is a chronic granulomatous disorder caused by Rhinosporidium seeberi . It frequently involves the nasopharynx and occasionally affects the skin. We report a case of 45-year-old man who had disseminated cutaneous rhinosporidiosis with cutaneous pseudohorn, its base arising from rhinosporidiosis. The case presented with multiple reddish lesions over the nose of six years duration. In the past year, he developed skin lesions over the left arm, forearm, back, and chest. On examination, polymorphic lesions of rhinosporidiosis in form of verrucous plaque, unulcerated tumor, granulomatous growth, and furunculoid lesions were observed. Interestingly, there was a cutaneous horn over the chest which on histopathological examination showed hyperplastic epithelium with numerous globular cysts of varying shape, representing sporangia in different stages of development and transelimination. Computerized tomography scan of the chest showed bilateral opacities suggestive of lung involvement. On the basis of these clinical and histopathological findings, a diagnosis of nasal rhinosporidiosis with cutaneous and systemic dissemination was made. [ABSTRACT FROM AUTHOR]

Background: The pattern of eczema is altered by geography, habits of people and environmental factors and regional variation in skin structure and function. Aims: Our study was done to estimate frequency and patterns of lower leg and foot eczemas. Methods: A total of 200 patients with various types of lower leg and foot eczemas were recruited over a period of 2 years. Demographic and clinical characteristics were noted. Suspected cases of allergic contact dermatitis were patch tested. Results: The frequency of these eczemas was 2.5 per 1000 out patients. Mean age of patients was 40.49 years. Female to male ratio was 1.6:1. Sixty (30%) patients were farmers, sixty (30%) were housewives, forty (20%) were students, nineteen (9.5%) were daily laborers, nine had sedentary jobs and three were teachers. Most eczemas were bilateral (72%). Mean duration of eczema was 36.6 months. Most common type of eczema was lichen simplex chronicus (36%) followed by discoid eczema (18.5%), allergic contact dermatitis (14.5%) and stasis eczema (7.5%). Other eczemas noted were juvenile plantar dermatosis, cumulative irritant contact dermatitis, infected eczema, hyperkeratotic eczema, asteatotic eczema, pompholyx, infective eczema and unclassified endogenous eczema. Common sites of involvement were dorsa of feet (49.5%), followed by lateral aspect of lower leg (31%), medial aspect of lower leg (17.5%) and ankle (12%). Conclusion: Our study highlights lichen simplex chronicus as the most common eczema affecting the lower legs and feet. [ABSTRACT FROM AUTHOR]

We describe two cases of methotrexate toxicity occurring due to inappropriate self-medication with the drug. The first patient was a 57-year-old man with plaque-type psoriasis on intermittent methotrexate therapy. He discontinued his medications for 2 months and had exacerbation of psoriasis for which he self-medicated with methotrexate following which he developed ulceration of the psoriatic plaques accompanied by bone marrow suppression. The second patient was a 68-year-old man with chronic plaque-type psoriasis for 20 years and was being treated with intermittent methotrexate for 15 years. He also self medicated with oral methotrexate 15 mg daily for 7 days for exacerbation of psoriasis and developed ulceration of the psoriatic plaques with bone marrow suppression and evidence of gastrointestinal erosions.

The author reflects the medical study for onychomycosis treatment in India. He describes onychomycosis as one of the intergumental fungal infects and nail disease in the country. Dermatophytes is demonstrated as the common cause in onychomycosis disease. He cites some alternative therapies of onychomycosis disease such as palliative care, mechanical/chemical debridement and other antifungal agents. He also illustrates some of the antifungal drug agents including terbinafine and itraconazole.

The article discusses the methods of specimen collection for the diagnosis of sexually transmitted infections (STIs). According to the authors, the correct method of specimen collection facilitates in achieving desirable goals in the laboratory diagnosis of STIs. They stress that if simple precautions are taken, it will avert spurious results. They also note that the collection of specimens and use of the appropriate swab and transport media are critical in the success of tissue culture.

Background: During pregnancy profound immunologic, metabolic, endocrine and vascular changes occur, that are responsible for the changes of the skin and its appendages, both physiologic and pathologic. Aims: We undertook a clinical study to find out the frequency and pattern of skin changes in pregnant women. Methods: All consecutive pregnant women were included in the study. Results: A total of 607 pregnant women were included in this study. Of these, 303(49.9%) pregnant women were primigravida and 304(51.1%) were multigravida. Skin changes grouped into: physiological changes (all cases), specific dermatoses (22 cases) and other dermatoses affected by pregnancy (125 cases). Most common physiological changes were pigmentary alterations seen in 555 (91.4%) followed by striae seen in 484(79.7%) cases. Of the various specific dermatoses of pregnancy, pruritic urticarial papules and plaques of pregnancy (PUPPP) was the most common disorder (14 cases) followed by pruritus gravidarum (5 cases). The most common dermatoses affected by pregnancy were candidal vaginitis (17 cases), acne vulgaris (15 cases), skin tags (15 cases), eczemas (14 cases). Conclusion: This study brings into focus various skin changes during pregnancy in south India. [ABSTRACT FROM AUTHOR]
