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.     

INCREASED INCIDENCE OF TUBERCULOSIS IN PATIENTS OF SYSTEMIC SCLEROSIS ON DEXAMETHASONE PULSE THERAPY: A SHORT COMMUNICATION FROM KASHMIR

Background:

Systemic sclerosis is a multi-systemic autoimmune disorder affecting predominantly the skin, lungs, gut and kidneys.

Purpose:

To report the increased incidence of tuberculosis in patients of systemic sclerosis on dexamethasone pulse (DP) therapy.

Methods:

Forty-seven patients of systemic sclerosis were included in the study. After taking a complete history and doing a detailed physical examination, the patients were submitted to a battery of investigations including complete hemogram (CBC) with erythrocyte sedimentation rate (ESR(F)), Chest X-ray CXR (PA view) Mantoux test and urine analysis. CBC, ESR and urine examination was done monthly and CXR were repeated six-monthly.

Findings:

Seven patients on DP therapy developed genitourinary tuberculosis. Four had pulmonary tuberculosis. One patient developed tubercular lymphadenitis, one patient succumbed to miliary tuberculosis.

Conclusion:

There is an increased incidence of tuberculosis amongst patients of systemic sclerosis on DP therapy.

Limitation of the Study:

There was no control group of systemic sclerosis patients not on DP therapy to rule out the confounding effect of the disease per se predisposing to tuberculosis as all our patients as a matter of routine were put on steroid pulse. Also, the increased incidence of tuberculosis was detected incidentally while on monthly follow-up.     

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.     

Cutaneous manifestations of deep mycosis: an experience in a tropical pathology laboratory

Background:

Cutaneous manifestations of deep mycotic infection are fraught with delayed or misdiagnosis from mainly cutaneous neoplastic lesions.

Aim:

This study is designed to present our experience of these mycoses in a pathology laboratory in the tropics.

Materials and Methods:

A clinicopathologic analysis of deep mycotic infections was conducted over a 15 years period Formalin fixed and paraffin wax processed biopsies were stained with hematoxylin and eosin, periodic acid Schiff (PAS), and Grocott''s methenamine silver (GMS) for the identification of fungus specie. Patients’ bio-data and clinical information were obtained from records.

Results:

Twenty males and seven females presented with 6 months to 6 years histories of varying symptoms of slow growing facial swellings, nodules, subcutaneous frontal skull swelling, proptosis, nasal blockage, epistaxis, discharging leg sinuses, flank mass, convulsion and pain. Of the 27 patients, four gave antecedent history of trauma, two had recurrent lesions which necessitated maxilectomy, two presented with convulsion without motor dysfunction while one had associated erosion of the small bones of the foot. None of the patients had debilitating illnesses such as diabetes mellitus, tuberculosis, and HIV infection. Tissue histology revealed histoplasmosis (10), mycetoma (9), subcutaneous phycomycosis (6), and phaeohyphomycosis (2).

Conclusion:

Deep mycoses may present primarily as cutaneous lesions in immunocompetent persons and often elicit distinct histologic inflammatory response characterized by granuloma formation. Diagnosis in resource constraint setting can be achieved with tissue stained with PAS and GMS which identifies implicated fungus. Clinical recognition and adequate knowledge of the pathology of these mycoses may reduce attendant patient morbidity.     

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.     

Limits of fine-needle aspiration cytology in diagnosing pilomatrixoma: a series of 25 cases with clinico-pathologic correlations

Background:

Pilomatrixoma (PMX) is a benign, quite uncommon, skin neoplasm, which is frequently misdiagnosed by clinicians.

Aim:

We have analyzed 25 PMX to determine the agreement between clinical diagnosis, preoperative FNA characteristics, and corresponding histopathological specimens; moreover, reliable cytologic criteria for PMX and the differential diagnosis to avoid cytological pitfalls have been emphasized.

Materials and Methods:

By fine-needle aspiration (FNA) cytology a series of consecutive cases of PMX collected during last 5 years were studied. Smears were stained by Papanicolau and May-Grünwald-Giemsa.

Results:

Patients affected by PMX were 11 males, 14 females (ratio 1:1.27); the mean age was 32.72 years with age range 3-78 years, being 72% (18/25) of patients 40 years or less. PMX was mainly distributed in the head-neck region (52%), scalp (16%), upper/lower arms (28%), and chest (4%). The observed diagnostic cytological features were represented by clusters of basaloid epithelial cells, shadow or ghost cells, inflammatory background, calcification, and giant cells. Unfortunately, not all these morphological aspects were always disclosed in smears, thus making the cytological preoperative diagnosis questionable and problematic.

Conclusions:

The experience of a well-trained cytopathologist should distinguish the relevant FNA features in terms of smear background, architecture, and cell morphology. The most dangerous mistake in FNA diagnosis of PMX regards a diagnosis of primary malignant or metastatic cutaneous lesions.     

Decreased effect of glucantime in cutaneous leishmaniasis complicated with secondary bacterial infection

Background:

Glucantime is regarded as the first-line treatment of cutaneous leishmaniasis (CL); however, failure to treatment is a problem in many cases.

Aim:

The aim was to evaluate the therapeutic effect of glucantime in CL complicated with secondary bacterial infection compared to uncomplicated lesions.

Methods:

This experimental study was performed in Skin Diseases and Leishmaniasis Research Center, Isfahan, Iran. A total of 161 patients enrolled in the study had CL confirmed by positive smear of lesions. All the patients were treated with systemic glucantime for 3 weeks and followed for 2 months. Response to treatment was defined as loss of infiltration, reepithelization, and negative smear. Depending on the results of bacterial cultures, the lesions were divided into two groups and the efficacy of glucantime was compared.

Results:

A total of 123 patients (76.4%) were negative, and 38 patients (23.6%) were positive for secondary bacterial infection. In groups with negative bacterial culture response to treatment was 65% (80 patients) and in the other positive group, it was 31.6% (12 patients), with a difference (χ² = 13.77, P < 0.01).

Conclusion:

Therapeutic effect of glucantime showed a decrease in CL lesions with secondary bacterial infection. Therefore, in the cases of unresponsiveness to treatment, the lesions should be evaluated for bacterial infection, before repeating the treatment.     

Plantar warts treated with topical adapalene

Background:

Treatment of plantar warts caused by human papilloma virus (HPV) strain types 1, 2 and 4 is often difficult and a challenging problem. Various therapeutic modalities available for treating this problem have not been uniformly successful.

Purpose:

The purpose of present study is to evaluate the efficacy of adapalene applied locally with occlusion in plantar warts.

Materials and Methods:

A total of 10 patient with 118 plantar warts were included in an open study. All were treated by applying adapalene gel 0.1% after paring of warts if needed followed by occlusive dressing with polythene paper in each patient. The effects of the treatment were evaluated every week till the clearance of all warts.

Findings:

Adapalene was used in 10 patient having 118 plantar warts. All the warts cleared in 39±15.07 days. There was no side effects like scar formation, irritation, erythema or infection with adapalene.

Conclusion:

Adapalene clears the plantar warts faster compared to other modalities available.

Limitation:

Need trial with large number of patients.     

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.     

Comparison of intralesional two percent zinc sulfate and glucantime injection in treatment of acute cutaneous leishmaniasis

Introduction:

Cutaneous leishmaniasis is an endemic disease in developing countries caused by different species of leishmania parasite, and if left untreated, it will result in a deformed scar after a relatively long period. Although various systemic and topical treatments have been proposed for leishmaniasis, pentavalent Antimony compounds remain the first-line treatment for it. Considering the cases with treatment failure, potential side effects and reluctance of patients to receive the drug, there are continuing efforts to find better treatment alternatives.

Aim:

Comparison of the effect of intralesional 2% zinc sulfate injection with Glucantime in treatment of acute cutaneous leishmaniasis.

Materials and Methods:

In this clinical trial, 45 patients with clinical diagnosis of cutaneous leishmaniasis and positive direct smear for leishman body were treated by intralesional injection of either 2% zinc sulfate or Glucantime. After simple randomization, in one group the patients were treated with 2 bouts of intralesional 2% zinc sulfate with a 2-week interval, and in the other group they were treated with 6 weekly bouts of intralesional Glucantime. The patients were monitored in two week intervals for 8 weeks. Healing of the lesions was evaluated clinically and by direct smear, and the data were analyzed using SPSS (11.5) software, t-Student, Mann-Whitney and Analysis of covariance (ANCOVA) statistical tests.

Findings:

In the end of study, 34 patients completed the study, 10 of whom received intralesional Glucantime and 24 of whom received intralesional 2% zinc sulfate. The healing rate after 8 weeks was 80% in the group receiving intralesional Glucantime and 33.3% in the one receiving 2% zinc sulfate (P=0.009).

Conclusion:

Based on the results of this study, intralesional injection of 2% zinc sulfate was less effective in treatment of cutaneous leishmaniasis than intralesional Glucantime.     

MUCOCUTANEOUS CHANGES IN TUBEROUS SCLEROSIS COMPLEX: A CLINICAL PROFILE OF 27 INDIAN PATIENTS

Background:

Tuberous sclerosis complex (TSC) is an autosomal dominant neurocutaneous disease resulting in a wide array of clinical manifestations, primarily affecting the skin and central nervous system. Mucocutaneous features play a very important role in the recognition of this syndrome.

Aims:

To review the prevalence and patterns of cutaneous manifestations in tuberous sclerosis, in a group of patients from eastern India.

Methods:

Observational clinical study on twenty-seven consecutive patients of tuberous sclerosis collected during a period of four years.

Results:

Most were between 10–20 years of age; the male to female ratio was 2:1. Family history was found in two-thirds. The classical triad of tuberous sclerosis was present in only nine (33.3%) patients. Adenoma sebaceum was the most common cutaneous feature (100%), followed by hypomelanotic macules (92.6%), connective tissue nevi (66.6%), and Koenen''s tumors (33.3%). Oral mucosal fibromas were seen in six (22.22%) patients. Fibromatous plaque over forehead and scalp was seen in three patients. Limitation of the study was small size of study sample.

Conclusion:

Prominent mucocutaneous changes are extremely common manifestation of TSC, which may provide crucial diagnostic clues for primary care physicians.     

ISOLATION OF BACTERIA CAUSING SECONDARY BACTERIAL INFECTION IN THE LESIONS OF CUTANEOUS LEISHMANIASIS

Background:

Cutaneous Leishmaniasis (CL) is a parasitic disease characterized by single or multiple ulcerations. Secondary bacterial infection is one of the complications of the disease that can increase the tissue destruction and the resulting scar.

Objective:

To effectively determine the incidence of real secondary bacteria infection in cutaneous leishmaniasis, we designed the current study.

Methods and Materials:

This was a cross-sectional study performed in Skin Diseases and Leishmaniasis Research Centre, Isfahan, Iran. In this study, 854 patients with confirmed CL were enrolled. Samples were taken from all the patients. Sterile swaps were achieved for the ulcer exudates and scraping was used for nonulcerated lesions. All the samples were transferred to tryptic soy broth medium. After 24 h of incubation in 37°C, they were transferred to eosin methylene blue agar (EBM) and blood agar. Laboratory tests were used to determine the species of bacteria. All of the collected data were analyzed by SPSS software and chi-square.

Results:

Among 854 patients with confirmed cutaneous leishmaniasis, 177 patients (20.7%) had positive cultures for secondary bacterial infection. Bacteria isolated from the lesions were as follows: Staphylococcus aureus - 123 cases (69.4%), coagulase negative Staphylococcus - 41 cases (23.1%), E. coil - 7 cases (3.9%), Proteus - 3 cases (1.7%) and Klebsiella - 3 cases (1.7%).

Conclusions:

The incidence of secondary bacterial infection in lesions of CL was 20.7%. The most common isolated pathogen was Staphylococcus aureus. The incidence of secondary bacterial infection was significantly more in the ulcerated lesions as compared with nonulcerated lesions (P = 0.00001).     

Mycetoma in Iran: Causative Agents and Geographic Distribution

Background:

Mycetoma is a chronic granulomatous disease caused by true fungi (eumycetoma) or filamentous bacteria (actinomycetoma). It usually involves the subcutaneous tissue after a traumatic inoculation of the causative organism. We reviewed retrospectively 13 patients with mycetoma.

Materials and Methods:

This study reports the etiologic agents and distribution of mycetoma in 35 cases from 1994 to2009 in Iran. The diagnostic of mycetoma were confirmed by histopathology and direct preparation, culture techniques, and histopathology of granules and surgical biopsies, radiological examination of the affected site.

Results:

Mycetoma was identified in 35 patients of 168 suspected patients (20.8%). They occurred in 22 male and 13 females. Their ages ranged from 14 to 80 years. The duration of the disease ranged from two months to 38 years. Sixteen patients had eumycetoma, and 19 patients had actinomycetoma, one of them had mix infections by eumycetoma and actinomycetoma. The majority of the patients were from central and states in south and north of Iran. The feet were most affected site (65.7%) of the cases, followed by hands (25.7%), face (2.8%), and trunk (2.8%), and buttock (2.8%). Most patients (68.5%) were more than 40 year-old. The male to female ratio was 5:3. The disease was abundant among housewife in urban and farmer in rural area of Iran. The most common prevalent mycetoma agents in this study were Actinomyces sp. There was a history of risk factors in 28.6% of patients in this study.

Conclusion:

Mycetoma occasionally occurs particularly in the South, Central, and North of Iran, and seen most often in persons, who live in hot, humid climates. If there are risk factors for invasive fungal infections traumatic inoculation with any fungus may result in rapid local spread and systemic disease, often with fatal outcome.     

Clinico-Mycological Study of Dermatophyte Toenail Onychomycosis in New Delhi,India

Introduction:

There is a constant need to define the epidemiological and mycological characteristics of onychomycosis (OM) for optimal management strategies.

Objectives:

To define the epidemiological and mycological characteristics of patients with dermatophyte toenail OM in a tertiary care hospital.

Materials and Methods:

Hundred consecutive patients of KOH and culture-positive dermatophyte toenail OM were subjected to detailed history, clinical examination and investigations.

Results:

Maximum number of patients (40%) belonged to 31-45 years age group and there was a male preponderance (M:F = 6.7:1). The mean duration of disease was 54 months. Thirty-three patients had fingernail involvement in addition to the toenail OM and 37% had co-existent cutaneous dermatophyte infection. Discoloration was the most common symptom (98%). Ninety-four (94%) patients had distal lateral subungual onychomycosis (DSLO) while two had superficial onychomycosis (SO) and only one had proximal superficial onychomycosis (PSO). Trichophyton interdigitale was the most common etiological agent (61%) followed by Trichophyton rubrum and Trichophyton verrucosum.

Conclusions:

Toenail OM is more common in males. DSLO was the most common clinical variant and T. interdigitale the most common etiological fungus responsible for toenail OM in our region. The importance of early diagnosis and treatment is highlighted as long-standing toenail OM predisposes to fingernail onychomycosis and recurrent tinea pedis.     

The impact of chronic urticaria on the quality of life in Indian patients

Backgound:

Besides the relief of symptoms, the main purpose of any treatment must be to ensure a better quality of life (QOL). Mere recording of symptoms reveals their severity and frequency, but gives scant information on its effect on QOL.

Aim:

The study was designed to assess QOL in Indian patients with chronic urticaia (CU).

Subjects and Methods:

We used the validated CU-QOL by Bairadani et al., consisting of five domains and each domain consisting of several items. Each item was scored from 1 to 5 (score 5 = most affected, score 1 = not affected).

Criteria for Inclusion:

Patients having symptoms of rash and pruritis on most of the days for at least 6 weeks were enrolled.

Criteria for Exclusion:

If the individuals had CU secondary to any other disease, they were excluded.

Results:

We enrolled 48 patients. The means of the domains, the items, and the frequency of occurrence of an item were tabulated. The highest mean scores were in the domains of symptoms, followed by sleep disturbances, life activities, looks, and limits. The highest mean scores for the items were for pruritis and wheals followed by sleep disturbances, mood changes, nervousness, embarrassment, fatigue, loss of concentration, reduced work, and social relationships. We also observed a significant relationship among individual items. It is possible that they may have an additive effect.

Conclusions:

Even though CU significantly affected many items, patients were rarely aware of them. There was a significant inter-item correlation, suggesting that items might be aggravating each other. It is important to address the issues regarding QOL along with symptoms for better management of CU.     

Genital/Perigenital Inflammatory Linear Verrucous Epidermal Nevus: A Case Series

Background:

Inflammatory linear verrucous epidermal nevus (ILVEN) is a distinct variety of keratinocytic epidermal naevus. In contrast to non-inflammatory epidermal naevi, ILVEN are far less common, usually erythematous and intractably pruritic. ILVEN usually appears at birth or early childhood and has a linear distribution following the Blaschko lines. Genital/perigenital involvement is relatively rare.

Objectives:

To describe the clinical features of 9 children with ILVEN localized to the genital and perigenital areas.

Method:

A retrospective study of 9 children with ILVEN presenting to a tertiary care Dermatology Clinic between 2007 and 2014 was undertaken. The clinical and histopathological features were reviewed.

Results:

Nine children (6 females, 3 males) were included in the study based on their characteristic clinicopathological features. The lesions were associated with severe itching in all cases. The mean age at presentation was 4 years (range 1-11 years). Onset of lesions was before 6 months of age in 8 patients. Left sided involvement was twice as common as the right sided one. Male patients had penoscrotal and groin involvement while all the female children had vulvar lesions. None of the children had any extracutaneous abnormalities. The children were treated with topical agents with variable relief or symptoms.

Conclusions:

The possibility of ILVEN should be considered in every linear genital lesion in children. We have presented the largest series of perigenital ILVEN reported in English literature.     

Human Papillomavirus Deoxyribonucleic Acid may not be Detected in Non-genital Benign Papillomatous Skin Lesions by Polymerase Chain Reaction

Background:

Papillomatosis is a known histopathologic pattern usually seen in human papillomavirus (HPV) infection and verruca vulgaris is the typical example. This pattern is also detected in some other benign cutaneous lesions such as nevus sebaceous (NS), seborrheic keratosis (SK), trichilemmoma (TL) and inverted follicular keratosis (IFK). The association between papillomatous lesions and HPV infection is questionable.

Objective:

The objective of this study was to investigate the presence of HPV deoxyribonucleic acid (DNA) in non-genital benign papillomatous skin lesions (NS, SK, TL and IFK) by polymerase chain reaction (PCR).

Materials and Methods:

A total of 100 specimens of non-genital NS, SK, TL and IFK were retrieved from archives of Dermatopathology Department of Razi Hospital, between 2003 and 2010. The conventional PCR using consensus GP5+/GP6+ primer and hydroxymethylbilane synthase gene as inner control was performed.

Results:

PCR for HPV DNA revealed no positive results in any of 28 seborrheic keratosis (SK), 28 nevus sebaceous (NS), 28 inverted follicular keratosis (IFK) and 13 trichilemmoma (TL) studied specimens.

Conclusion:

Papillomatosis is usually a characteristic pattern of HPV infection. However, we found no association between HPV infection and non-genital benign papillomatous lesions.     

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.     

The Rate and Pattern of Bcl-2 and Cytokeratin 15 Expression in Trichoepithelioma and Nodular Basal Cell Carcinoma: A Comparative Study

Context:

Histopathological evaluations can differentiate between clinically resembling trichoepithelioma (TE) and basal cell carcinoma (BCC) unless the biopsy specimens are small or superficial. Previous studies used immunohistochemical evaluation for Bcl-2 and cytokeratin 15 (CK15), in attempts to differentiate between these two entities, with heterogeneous findings.

Aims:

This study intended to compare the rate and patterns of Bcl-2 and CK15 expressions between specimens of TE and nodular BCC.

Settings and Design:

Case-series including formalin-fixed, paraffin-embedded cutaneous biopsies.

Subjects and Methods:

Twenty-two BCC and 12 TE specimens were stained for Bcl-2 and CK15 and examined microscopically. The rate and patterns of expressions were compared between the two groups.

Statistical Analysis Used:

Statistical analysis was performed using the statistical software (SPSS version 16.0; SPSS Inc., Chicago, IL, USA), Pearson Chi-square, or Fisher''s exact tests, wherever appropriate.

Results:

The two groups were comparable for the expression rate and patterns of Bcl-2 (86.4%: 5 central, 14 diffuse in BCC vs. 83.3%: 2 central, 8 diffuse in TE; P = 0.59 and 0.54 for rate and pattern, respectively). The rate of CK15 expression was significantly higher in TE specimens (66.7%: 4 central, 3 diffuse, 1 peripheral vs. 4.5%: 1 central; P < 0.001). The positive likelihood ratio in distinguishing the two neoplasms was 14.7 (95% confidence interval: 2.1-103.7).

Conclusions:

CK15 but not Bcl-2 staining may help in differentiating between BCC and TE even in BCCs with follicular differentiation.     

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.
