A case series of kaposi's varicelliform eruption in dermatology in-patients in a tertiary care centre

Background:

Recently, we noted increasing number of cases of Kaposi''s varicelliform eruption (KVE) among dermatology in-patients who were being treated for various dermatoses, some of which have not been reported earlier to be associated with KVE, and hence, this report.

Aims:

This study was designed to identify various dermatoses in which KVE occurred, to study the clinical features, course and response to specific antiviral treatment, to establish the risk factors, and course of the primary dermatoses during the episode of KVE.

Materials and Methods:

We analyzed our data of dermatology in-patients in a tertiary care centre in South India from April 2008 to November 2009 (20 months). The data were tabulated and analyzed.

Results:

Twenty cases (12 female and 8 male patients) of KVE were seen. The mean age of the patients was 46.4 years. There were seven cases of erythroderma, four of pemphigus vulgaris, three of toxic epidermal necrolysis, two of airborne contact dermatitis (ABCD), one each of lichenoid drug rash, and drug rash with eosinophilia and systemic symptoms (DRESS). Underlying dermatoses for erythroderma were: ABCD (3), psoriasis (3), and cutaneous T-cell lymphoma (1). Possible source of infection could be identified in five cases: exogenous sources in four cases and endogenous source in one case. The mean incubation period for cases with known source was 5 days (range, 2–9 days). Eighteen patients responded favorably to acyclovir. None of our patients had recurrent KVE during the study period.

Conclusion:

KVE may complicate any dermatosis where the integrity of the skin is compromised. Diagnosis and early treatment are important and possible in most cases if suspected.     

A clinicopathological study of cutaneous tuberculosis at Dibrugarh district, Assam

Background:

Cutaneous tuberculosis forms a small subset of extra pulmonary tuberculosis and has a worldwide distribution.

Aims:

The present study is an attempt to find out the incidence, clinical spectrum, and histopathological features of cutaneous tuberculosis.

Materials and Methods:

A total of 42 cases of newly diagnosed patients of cutaneous tuberculosis attending dermatology out patient department over a period of 1 year were included in the study. A detailed clinical examination and investigations including histopathological examination were carried out.

Results:

Scrofuloderma was the most common form seen in 50% cases followed by lupus vulgaris in 42.86%, tuberculosis verrucosa cutis in 4.76%, and lichen scrofulosorum in 2.38% cases. The Mantoux test was positive in 83.33% cases. Characteristic tuberculoid granulomas were seen in 72.22% cases of lupus vulgaris, 42.86% cases of scrofuloderma and all cases of tuberculosis verrucosa cutis and lichen scrofulosorum.

Conclusion:

Cutaneous tuberculosis is still highly prevalent in upper Assam. Early diagnosis and treatment are essential to prevent its complications.     

Pattern of pediatric dermatoses in a tertiary care centre of South West Rajasthan

Background:

The evaluation for skin disorders forms an important component of primary health care practice for all including children. The prevalence of certain skin diseases in children can reflect status of health, hygiene, and personal cleanliness of a community.

Aims:

This study was planned to evaluate the magnitude of skin diseases, pattern of various dermatoses, factors contributing to these dermatoses and concurrent systemic disease among children up to five years of age.

Materials and Methods:

Consecutive 1000 children, aged up to five years, attending the Dermatology OPD of RNT Medical College and MB Government Hospital, Udaipur were the subjects of this study. A detailed general, systemic and cutaneous examination followed by relevant investigations were carried out. The findings were recorded in a proforma for analysis and interpretation of data.

Results:

One thousand twenty seven (1027) diagnoses were made in 1000 children. Etiological analysis revealed that majority (417; 40.60%) of dermatoses belonged to infection and infestation group followed by eczematous (358; 34.86%) and hypersensitivity (105; 10.22%) groups. Of the infection and infestation group, bacterial infection (141; 13.72%) was the most common entity followed by scabies (107; 10.42%), fungal (67; 6.52%), and viral infection (35; 3.40%).

Conclusion:

This study provides a preliminary baseline data for future clinical research. It might also help to assess the changing trends of pediatric dermatoses.     

A clinical study of dermatoses in diabetes to establish its markers

Background:

Cutaneous manifestations of diabetes mellitus generally appear subsequent to the development of the disease, but they may be the first presenting signs and in some cases they may precede the primary disease manifestation by many years.

Aims:

The aim of our study was to study the spectrum of dermatoses in diabetics, to know the frequency of dermatoses specific to diabetes mellitus (DM), and to establish the mucocutaneous markers of DM.

Material and Methods:

The study was conducted at a diabetic clinic and our department between September 2008 and June 2010. Two hundred and twenty-four diabetic patients were included in the study group and those with gestational diabetes were excluded. Healthy age- and sex-matched individuals were taken as controls.

Results:

The male to female ratio was 1 : 1.21. Type 2 DM was seen in 89.7% and type 1 DM in 10.3% of the patients. Dermatoses were seen in 88.3% of the diabetics compared to 36% in non-diabetic controls (P<0.05). Cutaneous infections were the most common dermatoses followed by acanthosis nigricans and xerosis in diabetics. Type 2 DM was found to have an increased risk of complications than type 1 DM. Complications of diabetes were seen in 43.7% of the diabetic cases. Diabetic dermopathy, loss of hair over the legs, diabetic foot ulcer, and so on, were found to be the cutaneous markers of DM in our group of cases.

Conclusion:

Dermatoses were more common in diabetics than non-diabetics. Cutaneous infections formed the largest group of dermatoses in DM.     

A CROSS SECTION OF SKIN DISEASES IN RURAL ALLAHABAD

Background:

The pattern of skin diseases varies form one country to another and across different parts within the same country. A two-day multispecialty medical camp was held among the local population at the district of Kausambi, Allahabad, UP, in October 2005. A cross section of pattern of skin diseases observed at the camp is reported and compared with similar studies in literature.

Materials and Methods:

All cases attending the medical camp were included in the study. All those with dermatological complaints were examined in detail, brief relevant history was elicited and clinical diagnosis was made.

Results:

Skin diseases comprised 7.86% of all those who attended the camp. The 11–20 year age group was the most common age group involved with 164 (31.4%) cases. Infective disorders were found in 59.1% and noninfective disorders in 40.9% of all the skin cases. Among the infective disorders, fungal infections were most common (54.52%), and among the noninfective dermatoses, eczemas were most common (39.2%) cutaneous disorders.

Conclusion:

Our study brought out a higher prevalence of infective dermatoses and a relatively higher, but statistically insignificant, prevalence of fungal infections, scabies and eczemas, thereby reflecting minor regional variance in our study group.     

A clinicoepidemiological study of 50 cases of cutaneous tuberculosis in a tertiary care teaching hospital in pokhara, Nepal

Background:

Cutaneous tuberculosis (TB) is essentially an invasion of the skin by Mycobacterium tuberculosis, the same bacteria that causes pulmonary tuberculosis.

Aim:

This study was conducted to study the common types of cutaneous TB and to find the management pattern in a tertiary teaching hospital in Pokhara, Nepal.

Materials and Methods:

All the cases of cutaneous TB were biopsied and furthermore investigated by performing Mantoux test, sputum examination, fine needle aspiration cytology, chest X-ray and ELISA.

Results:

In this study, we found that tuberculosis verrucous cutis (48%) had a higher incidence than other types of cutaneous TB. More males were affected than were females (1.2:1). Commonly affected sites were the limb and the buttock (48%). The most commonly affected age group was 16–25 years (40%). All cases (except two) were more than 15 mm in size in the Mantoux test. The histopathological picture was typical in all except three cases. All patients were treated with antitubercular treatment as per the national guidelines.

Conclusion:

The most common type of cutaneous TB was tuberculosis verrucous cutis and the most commonly affected sites were the limb and the buttock. As cutaneous TB sometimes reflects the presence of pulmonary tuberculosis, its incidence should not be ignored.     

Severe Adverse Events Related to Tattooing: An Retrospective Analysis of 11 Years

Background:

The incidence of tattoos has been increased markedly during the last 20 years.

Aims:

To analyze the patient files for severe adverse medical reactions related to tattooing.

Settings:

Academic Teaching Hospital in South-East Germany.

Materials and Methods:

Retrospective investigation from March 2001 to May 2012.

Results:

The incidence of severe adverse medical reactions has been estimated as 0.02%. Infectious and non-infectious severe reactions have been observed. The consequences were medical drug therapies and surgery.

Conclusions:

Tattooing may be associated with severe adverse medical reactions with significant morbidity. Regulations, education and at least hygienic controls are tools to increase consumer safety.     

Simulation-Based Cutaneous Surgical-Skill Training on a Chicken-Skin Bench Model in a Medical Undergraduate Program

Background:

Because of ethical and medico-legal aspects involved in the training of cutaneous surgical skills on living patients, human cadavers and living animals, it is necessary the search for alternative and effective forms of training simulation.

Aims:

To propose and describe an alternative methodology for teaching and learning the principles of cutaneous surgery in a medical undergraduate program by using a chicken-skin bench model.

Materials and Methods:

One instructor for every four students, teaching materials on cutaneous surgical skills, chicken trunks, wings, or thighs, a rigid platform support, needled threads, needle holders, surgical blades with scalpel handles, rat-tooth tweezers, scissors, and marking pens were necessary for training simulation.

Results:

A proposal for simulation-based training on incision, suture, biopsy, and on reconstruction techniques using a chicken-skin bench model distributed in several sessions and with increasing levels of difficultywas structured. Both feedback and objective evaluations always directed to individual students were also outlined.

Conclusion:

The teaching of a methodology for the principles of cutaneous surgery using a chicken-skin bench model versatile, portable, easy to assemble, and inexpensive is an alternative and complementary option to the armamentarium of methods based on other bench models described.     

A cross-sectional study of dermatological problems among differently-abled children

Background:

Differently-abled children may be particularly susceptible to skin disorders either as a direct consequence of their disability or due of lack awareness regarding personal and environmental hygiene.

Aim:

To study the prevalence of skin problems in differently-abled children.

Materials and Methods:

A total of 122 differently-abled children in two special schools were examined for this study. Details regarding the disabilities were obtained from the school records.

Results:

More than half (53.2%) of the children had skin problems. Infections and infestations, acne, and dermatitis were the common dermatoses encountered in the present study.

Conclusion:

Periodic skin examination is of vital importance for all people with disabilities to reach a proper diagnosis and to offer treatment. Health education for teachers and parents on maintenance of sound personal hygiene and a clean environment is also recommended.     

A Study of Correlation Between Clinical and Histopathological Findings of Erythroderma in North Bengal Population

Background:

Erythroderma is a reaction pattern characterized by erythema and desquamation of 90% or more body surface area along with some metabolic alterations.

Materials and Methods:

Here we studied 32 patients of erythroderma at of North Bengal Medical College for a period of 1 year to find the etiology, clinical features and histological changes. Detailed history was taken from all the patients followed by relevant biochemical investigations and histological examination. To correlate the clinical and histopathological findings chi square test was used.

Results:

Male preponderance was present and most of them were in the 4^th or 5^th decade. Etiologically the patients were divided into secondary erythroderma developing over pre-existing dermatoses, and idiopathic erythroderma. Secondary erythroderma (n = 24) cases outnumbered the idiopathic cases (n = 8). Among the pre-existing dermatoses, psoriasis was found to be the most common etiologic agent. Apart from erythema the other common presenting features were scaling and itching. Histopathological categorization was possible in 59.3% cases, rest of the cases showed non-specific dermatitis. The most common histopathologic diagnosis was psoriasis (21.8% of cases).

Conclusions:

Our study of clinicopathological correlation of erythroderma patients among north bengal population corroborates with most of the previous studies done in other areas. As ours is a cross-sectional study in a undefined population so we could not determine the true incidence of erythroderma in north bengal population. We might have missed lymphoma as a cause of erythroderma in idiopathic cases due to lack of long follow-up, so we understand that further studies over a defined population with long follow-up is needed to determine the true incidence and causes of idiopathic erythroderma.     

THE ��HOLI�� DERMATOSES: ANNUAL SPATE OF SKIN DISEASES FOLLOWING THE SPRING FESTIVAL IN INDIA

Background:

‘Holi’ is an annual spring festival celebrated all over India. The central ritual of Holi involves throwing of colors on one another. Playing with toxic industrial dyes often results in various dermatological complaints in a significant number of people immediately following the celebration.

Aims:

To describe patterns of various skin manifestations directly or indirectly related to the use of different colors in the celebration of Holi.

Methods:

Observational clinical study on consecutive patients presenting to a teaching hospital in Kolkata, India.

Results:

Forty-two patients with a mean age of 24.2 years were studied. Itching was the commonest symptom (25, 59.5%), followed by burning sensation, pain, oozing, and scaling. Eleven patients’ symptoms were attributed to activities related to preparation of colors and the removal of colors from the skin surface. Eczematous lesions were the most common pattern (24, 57.1%) followed by erosions, xerosis and scaling, erythema, urticaria, acute nail-fold inflammation, and abrasions. Thirteen (30.9%) patients reported aggravation of preexisting dermatoses (acne, eczema, and paronychia). Secondary pyoderma occurred in 3 (7.1%). Face was the commonest site affected (24, 57.1%), followed by dorsum of the hands, scalp, forearm, palms, arms, and trunk. Ocular complaints in the form of redness, watering, and grittiness occurred in 7 (16.7%) patients.

Conclusion:

Various forms of cutaneous manifestations, often associated with ocular complaints, occur commonly due to Holi colors. Public awareness and regulatory actions are needed to avoid these preventable conditions.     

Mucocutaneous and demographic features of systemic sclerosis: a profile of 46 patients from eastern India

Background:

Systemic sclerosis (SSc) is a multisystem connective tissue disorder of uncertain etiology. The clinical picture is frequently dominated by prominent cutaneous manifestations that have diagnostic and prognostic significance. The objective of the present study was to find out the demographic profile and the relative frequencies and characteristics of different mucocutaneous features of SSc in a group of patients from eastern India. In addition, we sought to compare the frequency and pattern of the findings in the limited versus the diffuse variety of the disease.

Materials and Methods:

This was a cross-sectional, clinical observational study. Consecutive patients of SSc attending the dermatology O.P.D. of a tertiary care hospital of eastern India over 3 years were enrolled to the present study.

Results:

A total of 46 patients (41 females and 5 males; mean age 29.6±12.3 years) of SSc were evaluated. Among mucocutaneous manifestations Raynaud''s phenomenon was present in 39 (84.8%) patients. Other cutaneous features included dyspigmentation (40, 86.9%), sclerodactyly (38, 82.6%), inability to open the mouth (38,82.6%), mat-like telangiectasia (11,23.1%), fingertip ulceration and scarring (29,63%), cutaneous calcinosis (1,2.2%), digital gangrene in (2,4.3%), generalized pruritus (4,8.7%), cutaneous small vessel vasculitis (2,4.3%), chronic urticaria (2,4.3%), flexion contractures of the fingers (13,28.3%), and amputation of the digits (3,6.5%). Mucosal changes were observed in 10 (21.7%) patients and nail changes were seen in 13 (28.2%) patients. Diffuse cutaneous SSc was noted in 27 (58.7%) patients and limited cutaneous SSc was seen in the remainder. Thirty-six (78.2%) patients tested positive for ANA.

Conclusion:

The present study provides a snapshot of the spectrum of the demographic and mucocutaneous manifestations of SSc in the eastern Indian population. We have not observed any statistically significant differences between dcSSc and lcSSc in terms of mucocutaneous manifestations in the studied population.     

EFFICACY OF PULSED DYE LASER IN COSMETICALLY DISTRESSING FACIAL DERMATOSES IN SKIN TYPES IV AND V

Background:

Pulsed dye laser (PDL) has revolutionized treatment of vascular dermatoses. It has been successfully employed to treat several non-vascular conditions in fair skinned individuals without producing significant pigmentary and textural complications.

Aim:

A preliminary study was undertaken to assess its efficacy in cosmetically distressing facial, vascular and non-vascular dermatoses in Indian patients with skin types IV and V.

Materials and Methods:

Nine patients of ages 7 to 55 years, with facial verruca plana (VP- 4 cases), angiofibromas (AF- 4 cases) and multiple pyogenic granulomas (PG- one case) were recruited. They had no systemic complaints. Laser parameters used were (spot size/fluence/wavelength/pulse duration):VP- 5mm/5.5-7.5J/585nm/0.45ms; AF-5mm/6-8.5J/585nm/0.45ms;PG- 5mm/7J/585 and 595nm alternately/1.5ms. Response was assessed clinically and photographically.

Results and Conclusions:

All VP lesions completely resolved after 2-4 sessions (mean 3.25 sessions), AF showed 50% regression in all cases after 2-3 sessions (mean 2.5 sessions) and ≥75% subsidence after 3-7 sessions (mean 5.5 sessions) and in PG, after 3 sessions, there was complete subsidence of small satellite lesions with moderate shrinkage of larger papules and complete resolution after 5 sessions. Complications included transient hyperpigmentation/hypopigmentation only. There was no recurrence during next 6 months. PDL offers significant cosmetic improvement in facial dermatoses in Indian patients.     

Cutaneous manifestations of internal malignancy

Background:

Many malignancies affecting the internal organs display cutaneous manifestations which may be either specific (tumor metastases) or nonspecific lesions.

Aims:

The study is aimed at determining the frequency and significance of cutaneous manifestations among patients with internal malignancy.

Materials and Methods:

750 cases of proven internal malignancy, who attended a cancer chemotherapy center in South India, were studied. Specific infiltrates were confirmed by histopathology, fine needle aspiration cytology (FNAC) and marker studies.

Results:

Out of the 750 patients with internal malignancy, skin changes were seen in a total of 52 (6.93%) patients.

Conclusion:

Cutaneous metastases (specific lesions) were seen in 20 patients (2.66%): contiguous in 6 (0.8%), and non-contiguous in 14 (1.86%). Nonspecific skin changes were seen in 32 patients (4.26%). None of our patients presented with more than one type of skin lesions. Herpes zoster was the most common nonspecific lesion noticed in our patients, followed by generalized pruritus, multiple eruptive seborrheic keratoses, bullous disorder, erythroderma, flushing, purpura, pyoderma gangrenosum, insect bite allergy and lichenoid dermatitis.     

Applicability of Proposed Diagnostic Criteria of Pityriasis Rosea: Results of a Prospective Case-Control Study in India

Background:

The diagnosis of pityriasis rosea (PR) is generally clinical. Previous studies usually recruited relatively small numbers of patients and control subjects, leading to low power of study results. Systematic reviews and meta-analyses cannot be readily performed, as the inclusion and exclusion criteria of these studies were not uniform. We have previously validated a set of diagnostic criteria (DC) in Chinese patients with PR.

Aim:

Our aim is to evaluate the validity and applicability of the DC of PR in Indian patients with PR.

Study Design:

Prospective unblinded pair-matched case-control study.

Materials and Methods:

The setting is a dermatology clinic in India served by one board-certified dermatologist. We recruited all 88 patients seen by us during five years diagnosed to have PR to join our study. For each study subject, we recruited the next patient who consulted us with differential diagnoses of PR as control subjects. We applied the DC of PR on all study and control subjects.

Result:

The sensitivity, specificity, positive predictive value, and negative predictive value of the DC were all 100%. Two-tailed Fisher''s exact probability test result was 0.036. Φ was 1.00.

Conclusion:

The set of DC can be validly applied to Indian patients with PR.     

Steroid-induced rosacea: a clinical study of 200 patients

Background:

Topical corticosteroids were first introduced for use in 1951. Since then uncontrolled use (abuse) has caused many different reactions resembling rosacea – steroid dermatitis or iatrosacea. Multiple pathways including rebound vasodilatation and proinflammatory cytokine release have been proposed as the mechanism for such reactions.

Aim:

The aim was to study the adverse effects of topical steroid abuse and the response to various treatment modalities.

Materials and Methods:

Two hundred patients with a history of topical steroid use on face for more than 1 month were studied clinically and various treatments tried.

Results:

The duration of topical corticosteroid use varied from 1 month to 20 years with an average of 19.76 months. Majority of patients were using potent (class II) topical steroids for trivial facial dermatoses. The common adverse effects were erythema, telangiectasia, xerosis, hyperpigmentation, photosensitivity, and rebound phenomenon. No significant change in laboratory investigations was seen.

Conclusion:

A combination of oral antibiotics and topical tacrolimus is the treatment of choice for steroid-induced rosacea.
