Fractional Laser Resurfacing for Acne Scars: Our Experience at Tertiary Care Hospital of North India.

Background: Acne is very common among adolescents, which may sometimes persist into adulthood, and acne scars continue to have a profoundly negative impact on quality of life. Of all the various modalities available, fractional lasers have shown effective results. Aims and Objectives: The aim of this study was to assess the efficacy and safety of fractional carbon dioxide (CO2) laser resurfacing in atrophic facial acne scars. Materials and Methods: The study included 104 subjects aged ≥18 years with atrophic acne scars on face of more than 6 months of duration recruited over a period of 1 year. All the patients were treated with fractional CO2 laser (600 W power and wavelength 10,600 nm). Four sessions of fractional CO2 laser resurfacing were done at 6-week intervals in each patient. We compared the improvement rate of scars after every session at 6-week interval, 2 weeks after the last session, and finally 6 months after the last laser session. Results: The difference between the mean baseline score (3.43) and mean final score (1.83) using Goodman and Baron's qualitative scar scale was found to be statistically significant (P = 0.001). Mean improvement increased from first treatment session to the end of the treatment course from 0.56 to 1.62 indicating the role of the number of sessions in the overall improvement of acne scars. With regard to overall satisfaction, maximum number of patients were either very satisfied (55.8%) or satisfied (25%) as compared to those who were only slightly satisfied (11.5%) or completely unsatisfied (7.7%). Conclusion: Fractional ablative laser gives excellent results in the management of acne scars and has emerged as an appealing non-invasive option for this indication. Being a safe and effective option for atrophic acne scar treatment, it can be recommended wherever available.

Management of Pre-malignant and Malignant Non-melanoma Skin Cancers: A Study from a Tertiary Care Hospital of North India.

Introduction: The incidence of non-melanoma skin cancers (NMSCs) is increasing over the last few decades. This necessitates an early diagnosis which is nowadays aided by dermoscopy. Once diagnosed early, the treatment armamentarium is diverse and includes both topical and surgical modalities. Objective: Our aim was to diagnose pre-malignant and malignant NMSCs at an early stage and treat them as per the standard protocol. Materials and Materials: Out of 136 patients of pre-malignant and malignant tumors enrolled, 100 were taken up for treatment. These were then classified into various subtypes on the basis of clinical examination and dermoscopy. The selected patients were subjected to topical treatment or surgical modalities, wide local excision or flap excision, based on the type of tumor and its size. Results: The pre-malignant group included actinic keratoses, Bowen's disease, and keratoacanthoma, whereas the malignant group included undifferentiated squamous cell carcinoma (SCC), differentiated SCC, pigmented basal cell carcinoma (BCC), nodulo-ulcerative BCC, and superficial BCC. Actinic keratoses, superficial BCCs, and five cases of keratoacanthoma were treated with topical therapies with a resolution of 90% in 86.8% cases. All the remaining cases (62 in number) were treated with conventional and flap surgery with 88% and 89.1% clearance rates, respectively, with complications in only 7 patients. Conclusion: A prompt identification of NMSCs can enable selection of the appropriate treatment modality for a specific lesion and thus reduce their associated morbidity and mortality.

Efficacy of Fractional CO2 Laser for Improvement of Limited Mouth Opening in Systemic Sclerosis.

Background: Systemic sclerosis is a multisystem auto-inflammatory disease-causing fibrosis in the skin and internal organs. A frequent complication of systemic sclerosis is the limited mouth opening (LMO), a difficult-to-treat condition with only a few treatment options available. Aims and Objectives: The aim of this study was to evaluate the response of fractional carbon dioxide (CO2) laser resurfacing in LMO associated with systemic sclerosis. Materials and Methods: This was a hospital-based prospective study in which diagnosed cases of systemic sclerosis were taken. Patients who had significant LMO and who gave informed consent were included in the study. Fractional CO2 laser treatment was performed in the perioral area. Patients were assessed at baseline, after three and six sessions, and 3 months after the last session. Assessment was done by measurement of the interincisor distance (IID) using a ruler and calculation of the mouth handicap in systemic sclerosis (MHISS) scale. Results: Improvement in IID occurred 3 months after the first session with a mean gain of +5 mm (range 2-7). At 6 months, a mean gain of +8.5 mm (range 7-10) in IID was observed (P < 0.001). The MHISS score decreased by a mean of 14 (range 11-17) (P < 0.001). All patients showed improvement of mouth opening, which allowed the patients to have better phonation and the patients were able to have proper dental care posttreatment in the form of brushing of teeth and other dental procedures. The adverse effects noted in these patients included erythema that resolved spontaneously or after icing posttreatment. Other adverse effects noted were stinging and burning sensations that were mild and transient. Conclusion: Fractional CO2 laser forms a safe, effective, and well-tolerated treatment modality for improvement of LMO in systemic sclerosis. Limitations: The limitations of this study were less number of patients and no long-term follow-up.

Clinical Pattern and Patch Test Profile of Hand Eczema in Hospital Employees in a Tertiary Care Hospital of North India.

INTRODUCTION: Health care workers form an important occupational group with a high risk of hand eczema. All health care professionals are exposed to a variety of allergens and irritants which can cause hand dermatitis, resulting in significant morbidity. AIMS AND OBJECTIVES: To assess the clinical profile of hand eczema in hospital employees, to perform patch test in relevant cases and to find out the most common sensitizers in them. MATERIALS AND METHODS: This was a cross-sectional, hospital-based study in which the staff was screened for features of hand eczema and patch testing was done in the suspected cases of allergic contact dermatitis. RESULTS: Out of 340 employees screened, 46 employees (13.5%) suffered from hand eczema. The most common type was wear and tear dermatitis accounting for 17 (36.9%) cases, followed by discoid eczema, pompholyx, focal palmar peeling, finger-tip eczema, hyperkeratotic eczema, ring eczema, and unspecified types. Patch testing was positive in 15 (32.6%) cases. The most common allergen was paraphenylene diamine, followed by fragrance mix, nitrofurazone, mercaptobenzothiazole, potassium bichromate, black rubber mix, and thiuram mix. A statistically significant association (0.001) was found with an underlying history of atopy. CONCLUSION: Hand eczema is a commonly encountered dermatological complaint in many hospital employees. Proper counseling, work, up, patch testing, and treatment can mitigate the symptoms in such employees.

Etiopathological and Clinical Study of Acute Generalized Exanthematous Pustulosis: Experience from a Tertiary Care Hospital in North India.

BACKGROUND: Acute generalized exanthematous pustulosis (AGEP) is a type of severe cutaneous adverse reaction that is characterized by the rapid development of nonfollicular, sterile pustules on an erythematous base. OBJECTIVES: The aim of our study was to enroll all cases of AGEP reporting to our department over a period of one year and to find out the clinical and etiological profile of the patients. MATERIALS AND METHODS: All the patients reporting to our department with clinical features suggestive of AGEP were enrolled for the study. Careful history and examination were done to rule out other causes of pustular eruptions, which can resemble AGEP. AGEP validation score of the EuroSCAR study group was used to establish the diagnosis. RESULTS: A total of 16 patients were enrolled during the study period of one year. The majority of the patients were females with a mean age of 28.41 ± 12.2 years. Twelve (75%) of the patients had a history of drug intake while 4 (25%) had developed AGEP following an insect bite. Penicillins were the causative factor in five patients followed by cephalosporins in three patients, nonsteroidal anti-inflammatory drugs (NSAIDs) in 2 patients, and terbinafine in 1 patient. Tetanus toxoid was responsible for the development of AGEP in one patient. The insect bites were all spider bites. CONCLUSION: AGEP is a rare type of severe cutaneous adverse drug reaction.We encountered 16 patients of AGEP over a period of one year. An important cause of AGEP was spider bite in our study group.

Clinicoepidemiological and Patch Test Profile of Patients Attending the Contact Dermatitis Clinic of a Tertiary Care Hospital in North India: A 7-Year Retrospective Study.

INTRODUCTION: Allergic contact dermatitis (ACD) is a growing concern due to increased use of cosmetics and topical medications routinely and exposure to a large number of allergens on day-to-day basis. Patch testing is a reliable method for detecting the causative antigens in suspected cases. AIMS AND OBJECTIVES: To assess the demographic profile, pattern of ACD, and patch test profile of suspected cases of ACD attending contact dermatitis clinic of our department. MATERIALS AND METHODS: It was a retrospective study in which all the data enrolled in the contact dermatitis clinic of our department over a 7-year period were analyzed. Patch testing was done using the Indian Standard Series of 20 antigens primarily, and other batteries were used depending on patient requirement and availability. RESULTS: A total of 582 patients were enrolled in the contact dermatitis clinic over a period of 7 years. Hand eczema was the most common pattern seen in 268 cases followed by feet eczema, hand and foot eczema, facial eczema, forearm and leg eczema and photoallergic contact eczema. A total of 177 patients (30.4%) gave positive patch test results, with nickel sulfate being the most common allergen identified followed by potassium dichromate, cobalt sulfate, paraphenylenediamine, neomycin sulfate, and fragrance mix. CONCLUSION: Common allergens identified in our study were more or less similar to studies from other parts of India. However, due to the unique climate of the valley, the profile of parthenium sensitivity was low in our study when compared to the rest of the country.

Common Contact Allergens in Patients with Palmoplantar and Scalp Psoriasis and Impact of their Avoidance on Dermatology Life Quality Index: A Hospital-Based Study.

BACKGROUND: Scalp psoriasis and psoriasis limited to palms and/or soles have been referred to as difficult to control psoriasis. Contact allergy has long been suspected to aggravate existing lesions and cause resistance to therapy in these psoriasis variants. OBJECTIVES: The objective of the study was to assess common contact allergens in patients with palmoplantar and scalp psoriasis and the impact of their avoidance on dermatology life quality index (DLQI). MATERIALS AND METHODS: A total of 54 patients with palmoplantar and scalp psoriasis were patch tested with Indian Standard Series. The patch test results were read on day 2 and day 4. DLQI was calculated before patch testing and at 1 month and 3 month in patch test positive patients after instructing allergen avoidance. RESULTS: Sixteen out of fifty-four patients (29.62%) showed positive patch test reactions. Metal antigens like nickel and cobalt were the most common sensitizers identified. Statistically significant improvement in DLQI was observed at 1 month and at 3 month of allergen avoidance. CONCLUSION: Patch testing is a useful test to determine the triggering or aggravating antigens in patients with palmoplantar and scalp psoriasis and subsequent allergen avoidance should be stressed on.

Contact dermatitis caused by tulips: identification of contact sensitizers in tulip workers of Kashmir Valley in North India.

BACKGROUND: Tulip, belonging to the genus Tulipa and family Liliaceae, is a spring-blooming perennial that grows from bulbs. Owing to manual handling, contact dermatitis can occur in professionals at any stage of the growth cycle of the tulip plant. OBJECTIVES: To determine the clinical pattern of contact dermatitis resulting from tulip plant cultivation, and to assess contact allergy in workers coming into contact with this plant. METHODS: One hundred and sixty-four tulip workers were screened, and 48 patients with suspected contact dermatitis were patch tested with 39 allergens, including haptens from the Indian baseline series, a plant series, and extracts from different parts of the tulip plant. RESULTS: Thirty-nine positive patch test reactions were observed in 21 patients. Seventeen patients showed positive reactions to either α-methylene-γ-butyrolactone or to tulip plant extract. Clinical relevance was observed for 13 of 17 positive patch test reactions. CONCLUSIONS: Contact dermatitis is an important health hazard in workers dealing with tulip bulbs. Further studies to identify and isolate other possible tulip allergens, and to quantify the amounts of allergens in different parts of the tulip plant, are recommended.

Occupational Dermatoses among Cottage Industry Workers of Kashmir Valley in North India.

INTRODUCTION: Cottage industry is usually a small-scale industry operated from home by family members using their own equipment. Kashmir has a unique cottage industry of its own which deals with production of many handicrafts, which may lead to a peculiar pattern of skin diseases in these artisans. Aim: The aim of this study was to find out the pattern of skin disorders in the cottage industry workers of Kashmir valley, with primary focus on the occupation-related dermatoses and to identify the most common cutaneous manifestation in these workers. MATERIALS AND METHODS: This was a cross-sectional descriptive study in which 1062 cottage industry workers engaged in different crafts were screened. A detailed history taking and examination was carried out in each worker and the diagnosis was made on clinical grounds. Wherever deemed necessary, relevant investigations were done to establish the nature of the disease. RESULTS: A total of 1062 workers were evaluated for the presence of skin disorders. The male-to-female ratio was 1:1.5. The mean age of the study group was 30.3 years ± 10.79 years, with maximum number of workers (164) belonging to the crewel embroidery industry. The mean duration of work was 6.4 ± 2.08 hours/day. A total of 953 workers (89.7%) had cutaneous manifestations, with callosities being the most common finding seen in 371 workers (35%), followed by cumulative insult dermatitis seen in 201 workers (19%). CONCLUSION: Cottage industry of Kashmir valley is a unique occupational group where a high percentage of workers had cutaneous manifestations related to their occupation, with callosities being the most common finding. Information and better knowledge regarding these dermatoses are important in devising strategies to improve the health scenario of these workers. Simple measures such as proper use of instruments, use of protective gloves, guarded use of chemicals, and hand washing may be very beneficial in reducing the burden of health problems in these workers.
