Investigating dysregulation of TGF-ß1/SMAD3 signaling in Atopic Dermatitis: A Molecular and Immunohistochemical Analysis".

Atopic Dermatitis (AD) is a persistent and recurring inflammatory condition affecting the skin. An expanding corpus of evidence indicates the potential participation of TGF-ß1 in the modulation of inflammation and tissue remodeling in AD. The primary objective of this study was to examine the aberrant modulation of TGF-ß1/SMAD3 signaling through a comprehensive analysis of their molecular and protein expression profiles. The study encompassed an aggregate of 37 participants, which included 25 AD patients and 12 controls. The assessment of mRNA and protein levels of TGF-ß1 and SMAD3 was conducted utilizing quantitative real-time PCR and immunohistochemistry, whereas serum IgE and vitamin D levels were estimated by ELISA and chemiluminescence, respectively. Quantitative analysis demonstrated a 2.5-fold upregulation of TGF-ß1 mRNA expression in the lesional AD skin (p<0.0001). Immunohistochemistry also exhibited a comparable augmented pattern, characterized by moderate to strong staining intensities. In addition, TGF-ß1 mRNA showed an association with vitamin D deficiency in serum (p<0.02), and its protein expression was linked with the disease severity (p<0.01) Furthermore, a significant decrease in the expression of the SMAD3 gene was observed in the affected skin (p = 0.0004). This finding was further confirmed by evaluating the protein expression and phosphorylation of SMAD3, both of which exhibited a decrease. These findings suggest that there is a dysregulation in the TGF-ß1/SMAD3 signaling pathway in AD. Furthermore, the observed augmentation in mRNA and protein expression of TGF-ß1, along with its correlation with the disease severity, holds considerable clinical significance and emphasizes its potential role in AD pathogenesis.

Interleukin 4 and Interleukin 4 receptor alpha gene variants and risk of atopy - A case control study based assessment.

INTRODUCTION: IL4 pathway is known to upregulate IgE mediated immune responses and responsible for the manifestation of Atopic disorders. The current study was aimed to elucidate the genetic variations of Interleukin 4 (IL4) and Interleukin 4 receptor alpha (IL4R) genes and their possible association with atopic subjects. METHODS: The well-designed questionnaire was used to collect the subject demographic and clinical details. Biochemical parameters were analysed using Chemiluminescent Immunoassay (CLIA) technique. The genotyping was performed using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP). RESULTS: We observed a statistically significant difference of serum Immunoglobulin-E (IgE) levels among cases and controls (P<0.05). Subjects harbouring the variant genotypes of I50V and Q576R single nucleotide polymorphisms (SNPs) in IL4R gene showed statistically differential risk towards atopic disorders. However, the variants genotype of 70 bp VNTR polymorphism in IL4 gene showed a protective role towards in predisposition to Atopy. On stratification, the above genetic variants had a significant impact on modifiable and non-modifiable factors associated with the disease. CONCLUSION: Our study demonstrates that increased IgE levels and IL4 gene variants (I50V and Q576R) are significantly associated towards predisposition to allergic disorders in this study population.

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.

Treatment of post-burn and post-traumatic atrophic scars with fractional CO2 laser: experience at a tertiary care centre.

Scars are abnormal wound responses in predisposed individuals. They occur after any kind of wound and skin inflammation in predisposed individuals. Despite their benign nature, they can be aesthetically disabling. Although several approaches have been tried in their management, most of them have produced poor results. This study aims to assess the efficacy and safety of fractional CO2 laser treatment in the management of post-burn and post-traumatic scars. One hundred consecutive patients (77 females and 23 males) affected by post-burn scars as well as post-traumatic atrophic scars were treated with monthly sessions of fractional CO2 laser treatment. Patient's response to treatment was assessed clinically as well as improvement of scars by comparing the photographs taken before treatment with those taken 6 months after the last treatment session. Changes in skin texture, surface irregularity and pigmentation were assessed on a quartile grading scale and scored individually from 0 to 4. A mean of the three individual scores was calculated and the response was labelled as 'excellent' if the mean score achieved was > 3. A score of 2-3 was labelled as good response while a score below 1 was labelled as 'poor' response. A mean of six treatments per scar were required and all patients, followed up for 1 year after the last treatment, had optimum results and no recurrence. Response to treatment was excellent in 53.75%, good in 16.25% patients, and poor in 30% patients. Fractional CO2 laser gives a very good result in the management of patients with post-burn scars as well as post-traumatic scars with minimal adverse effects.

Footwear Contact Dermatitis: A Prospective Cross-Sectional Study of 108 Outpatients from Delhi, India.

Footwear contact dermatitis is a common problem with multifactorial exogenous, as well as endogenous, etiologies. Patch testing is the gold standard for detection of the possible contactants. A cross-sectional study was conducted in 108 outpatients over a period of 18 months. Demographic data comprising age, sex, and occupation were collected. Details of clinical and laboratory investigations were used to define the incriminating ingredient(s), subsequently confirmed by patch test using Indian standard and footwear series approved by the Contact and Occupational Dermatitis Forum of India. Reading and interpretation were carried out according to the International Contact Dermatitis Research Group (ICDRG) guidelines. Of the 108 patients, 64 were girls or women and 44 boys or men. Although footwear contact dermatitis affected all age groups, most individuals were 21 to 40 years old. The morphology and distribution of the lesions were very specific. Patch testing was helpful, the primary sensitizing agent being mercapto mix, followed by mercaptobenzothiazole, potassium dichromate, and paraphenylenediamine. Footwear contact dermatitis is an extraordinary entity, requiring a high level of expertise (or knowledge) to determine its etiology through history, clinical examination, and patch testing.

Assessment of esophageal involvement in systemic sclerosis and morphea (localized scleroderma) by clinical, endoscopic, manometric and pH metric features: a prospective comparative hospital based study.

BACKGROUND: Systemic sclerosis (SSc) is a generalized disorder of unknown etiology affecting the connective tissue of the body. It affects the skin and various internal organs. Gastrointestinal tract involvement is seen in almost 90% of the patients. Esophagus is the most frequently affected part of the gastrointestinal tract. Esophageal motility disturbance classically manifests as a reduced lower esophageal sphincter pressure (LESP) and loss of distal esophageal body peristalsis. Consequently, SSc patients may be complicated by erosive esophagitis and eventually by Barrett's esophagus and esophageal adenocarcinoma. Morphea, also known as localized scleroderma, is characterized by predominant skin involvement, with occasional involvement of subjacent muscles and usually sparing the internal organs. The involvement of esophagus in morphea has been studied very scarcely. The proposed study will investigate the esophageal involvement in the two forms of scleroderma (systemic and localized), compare the same and address any need of upper gastrointestinal evaluation in morphea (localized scleroderma) patients. METHODS: 56 and 31 newly and already diagnosed cases of SSc and morphea respectively were taken up for the study. All the patients were inquired about the dyspeptic symptoms (heartburn and/or acid regurgitation and/or dysphagia). Upper gastrointestinal endoscopy, esophageal manometry and 24-hour pH monitoring were done in 52, 47 and 41 patients of SSc; and 28, 25 and 20 patients of morphea respectively. RESULTS: Esophageal symptoms were present in 39 cases (69.6%) of SSc which were mild in 22 (39.3%), moderate in 14 (25%), severe in three (5.3%); while only four cases (7.1%) of morphea had esophageal symptoms all of which were mild in severity. Reflux esophagitis was seen in 17 cases (32.7%) of SSc and only two cases (7.14%) of morphea. Manometric abnormalities were seen in 32 cases (68.1%) of SSc and none in morphea. Ambulatory 24-hour esophageal pH monitoring documented abnormal reflux in 33 cases (80.5%) of SSc and no such abnormality in morphea. CONCLUSION: While the esophageal involvement is frequent in SSc, no such motility disorder is seen in morphea. Meticulous upper gastrointestinal tract evaluation is justified only in SSc and not in morphea.

Histopathological examination of nail clippings using PAS staining (HPE-PAS): gold standard in diagnosis of Onychomycosis.

Onychomycosis is fungal infection of one or more of the nail units. However, because fungi cause only about half of all nail dystrophies, the use of appropriate diagnostic techniques is important to ensure correct diagnosis and treatment. Aim of the present study was to compare direct microscopy, culture and HPE-PAS for diagnosis of onychomycosis by evaluating their sensitivity and various other relevant statistical parameters. A prospective, hospital-based, cross-sectional study was conducted on 216 patients with a high degree of clinical suspicion of onychomycosis. Nail specimens were evaluated using three diagnostic methods, i.e. direct microscopy using 20% Potassium hydroxide (KOH) & 40% Di-methyl-suphoxide (DMSO), culture and histopathological examination using PAS stain (HPE-PAS). Of 216 patients direct microscopy was positive in 138 (63.9%), culture in 147 (68%) and HPE-PAS in 164 patients (76%). One hundred and seventy-nine patients fitted into the criteria set for confirmed diagnosis of onychomycosis. Using this as a denominator; direct microscopy, culture and HPE-PAS had sensitivities of 77.1%, 70% and 91.6% respectively. Also, HPE-PAS showed the highest sensitivity of 94.7% in 19 cases with prediagnostic antimycotic treatment compared to direct microscopy (42.1%) or culture (57.9%). HPE-PAS shows high sensitivity for diagnosis of onychomycosis and can be considered as a gold standard in the diagnosis of onychomycosis.

Diagnostic Utility of Nailfold Capillaroscopy using Hand-held Dermoscope in Systemic Sclerosis.

Introduction: The pathogenesis in systemic sclerosis (SSc) mainly involves vascular injury, fibrosis, and immune activation. Visualization of these microvascular changes by nailfold capillaroscopy (NFC) can help in the early diagnosis of the disease. Even though the gold standard for NFC is a videodermoscope, the ease, practicality, and accessibility make the hand-held dermoscope a more versatile and suitable device in the hands of the dermatologists in the busy outpatient department. Aim: To study the pattern of nail fold capillaries using hand-held dermoscope in the patients of SSc and correlate the findings with disease severity. Materials and Methods: An observational, cross-sectional hospital-based study was carried out over a span of 2 years, from January 2020 till December 2021, in 50 patients of SSc. NFC using DermLite DL4 was performed in all the patients and distribution, morphology, density of capillaries, and nail fold capillary pattern were observed. Results: Out of 50 patients, 38 patients had diffuse type of disease, and 12 had limited type of disease. The mean capillary density in our patients was 4.7 ± 0.81/mm. Dilated capillaries was the most common NFC finding (80%), whereas active scleroderma pattern was the most common pattern (56%). A significant association was found between the type of capillary pattern and duration of disease, type of disease, and cutaneous manifestations. Conclusion: Hand-held dermoscope is reliable, practical, and assessable tool that aids in early diagnosis of the disease and also helps in assessing the severity and prognosis of SSc.

Increasing the Safety Profile of Follicular Unit Extraction by Eliminating the Use of Bupivacaine and Nerve Block: Experience from a Tertiary Care Center of North India.

Introduction: Follicular unit extraction (FUE) is a safe and effective procedure in the hands of an expert. Side effects, particularly those which can lead to significant morbidity or mortality, are unacceptable as the procedure is done purely for cosmetic reasons. Any modification that decreases the risk associated with the procedure should be promoted. Aim and Objective: The study was conducted to determine whether FUE can be carried out effectively with the elimination of nerve blocks and bupivacaine from the procedure. Materials and Methods: The study was conducted in 30 patients suffering from androgenetic alopecia. The donor areas was anesthetized using lignocaine with adrenaline just below the area to be harvested. The anesthetic was injected intradermally resulting in the development of wheals in continuity, forming a linear line. From our previous experience, we found intradermal administration of lignocaine to give better anesthetic effect as compared to subcutaneous administration, although the former is more painful. This was followed by injection of tumescent into the donor area and donor harvesting, which lasted for a couple of hours. The recipient area was anesthetized using a similar technique of linear injection of anesthetic just ahead of the proposed hair line. Results: The total amount of lignocaine with adrenaline consumed during the surgery ranged from a minimum of 6.1 ml to 8.5 ml, with an average of 7.6 ml. The average duration of the entire surgery was 6.5 h, ranging from 4.5 to 8.5 h. None of the patients experienced any pain during the entire surgery, and there were no significant side effects related to anesthetic administration in any patient. Discussion: We found lignocaine with adrenaline to be a very safe and effective anesthetic agent for field block anesthesia in FUE. The exclusion of bupivacaine and nerve blocks from the procedure of FUE can further increase the safety of the procedure, particularly for beginners and in cases where the area to be covered is not extensive (Norwood-Hamilton grades 3, 4, and 5).

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.

Rituximab in Pemphigus - An Observational Study from a Tertiary Care Center of North India.

Background: Pemphigus is a group of potentially fatal autoimmune mucocutaneous blistering diseases. Rituximab (RTX) is a chimeric anti-CD20 (anti-cluster of differentiate 20) monoclonal antibody being increasingly used and becoming the first-line therapy in the management of pemphigus. Aims and Objectives: This was an observational study to evaluate the efficacy and safety of rituximab in patients of pemphigus vulgaris (PV) who either did not respond or relapsed after conventional therapeutic regimens and in treatment naive pemphigus patients. Materials and Methods: The study included pemphigus patients coming to our immunobullous clinic who did not respond to conventional therapy or relapsed after receiving conventional therapy as well as fresh cases between January 2019 and October 2021. All enrolled patients received two doses of rituximab (1 gram in each) as intravenous infusions two weeks apart as per the rheumatoid arthritis protocol. The efficacy and safety were evaluated by assessing pemphigus area and activity score (PAAS) before and after the therapy, clinical response, and any adverse events during follow-up. Results: Sixteen (ten males and six females) patients were included in the study. The age of these patients ranged from 27 to 60 years, with a mean of 43.8 ± 9.8 years. There were 15 (93.75%) patients with PV (14 mucocutaneous type and 01 mucosal) and one (6.25%) with pemphigus foliaceus. Among these patients, nine (56.25%) were relapse cases, four (25%) were non-responders, and three (18.75%) were fresh cases who received rituximab as first-line therapy. Fourteen (87.5%) patients reached complete remission off therapy over a median time of 6.36 months (ranging from 18 weeks to 35 weeks). Rituximab was well-tolerated by our patients, and no serious adverse events were observed. The main limitation of our study was the small sample size and the lack of a comparison group. Conclusion: Rituximab is a safe and effective treatment for pemphigus.

Prevalence and Pattern of Dermatological Manifestations Among Substance Users Across Kashmir Valley in North India.

Background: Substance use has turned out to be one of the growing social problems of the present society cutting across all sorts of boundaries of the world with Kashmir Valley being no exception to this growing pathological phenomenon. Aims and Objectives: To find the prevalence and pattern of dermatological manifestations among substance users across Kashmir Valley. Materials and Methods: Cross-sectional study where patients of all age-groups, irrespective of gender, were enrolled in the three largest districts of Kashmir Valley over a span of 18 months. Results: Sample size was 710 with a male/female ratio of 12.4:1. The mean age of the cases was 25.2 ± 7.05 years. Heroin, one of the opioids, was the most common substance used (n = 515), followed by cannabis (n = 334). Pruritus was found to be the most common dermatological manifestation overall and statistically significant among heroin users. Stigmata of injection drug use (IDU) with the presence of track marks and sooting tattoos (93.1%), atrophic scars secondary to skin popping (30.7%), active skin ulcers (18.8%), and puffy hand syndrome (8.7%) were specifically seen among injection drug users. Oral involvement was seen in 48.5%, including periodontal disease, oral thrush, and stomatitis nicotinica. Hyperhidrosis was present in 30%, and hesitation cuts over arms in 16.3% of all substance users. Conclusion: Dermatological manifestations are quite prevalent among substance users in the population of Kashmir. Pruritus with temporal relation to substance use, stigmata of injectable drug use including track marks and sooting tattoos, atrophic scars at injection sites, active skin ulcers, and skin and soft tissue infections, and hyperhidrosis are among important dermatological clues for detecting substance use. Recognition of such cutaneous signs is important in these cases for more effective diagnosis and treatment.

Dermoscopy of Oral Mucosal Lesions: Experience from a Tertiary Care Center in North India and Review of Literature.

Background: Patients with mucosal lesions form a significant number of routine outpatients presenting to the dermatology department where diagnostic confirmation using histopathological examination of mucosal biopsy is neither feasible nor warranted in every patient. Objective: To study the dermoscopic features of various mucosal lesions affecting the oral cavity and to assess the reliability of mucoscopy vis-a-vis clinico-laboratory findings. Materials and Methods: An observational, cross-sectional, hospital-based study was conducted over a period of 2 years from March 2019 to February 2021 in the dermatology outpatient department. Patients presenting with oral mucosal lesions, with or without associated cutaneous involvement, were recruited for mucoscopic evaluation after taking an informed written consent. A detailed history and clinical examination, with emphasis on mucocutaneous examination, was performed and findings were recorded on a standard predesigned proforma. Mucoscopy of oral mucosa was carried out using a handheld dermoscope as well as Universal Serial Bus connected video-dermoscope in both nonpolarized and polarized modes. The different mucoscopic features were seen at these sites, compared with each other, analyzed and findings were recorded. A diagnosis was made on the basis of mucoscopic findings and correlated with clinical diagnosis. The data was analyzed using appropriate statistical tests. Results: The mean age of patients was 34.3 years and the mean lesional duration was 68.2 weeks. Oral lichen planus (18.66%) was the most common disorder studied, followed by recurrent apthous stomatitis (16.00%), pigmentary lesions (12.66%), vascular disorders (12.00%), mucocele (5.33%), pemphigus vulgaris (4.66%), and discoid lupus erythematosus (4.66%). Conclusion: Dermoscopy in oral lesions facilitates the visualization of the mucosal surface and provides quick confirmation of diagnosis in various mucosal disorders with advanced diagnostic accuracy. Mucoscopy was found helpful in differentiating the oral ulcers, which are a presenting feature of various serious mucocutaneous disorders. Mucoscopy could be a helpful aid in diagnosing pigmented skin lesions and alleviating the apprehension regarding oral melanoma and serve as a screening tool in case of squamous cell carcinoma lips. Limitations: Confirmatory histopathological analysis and correlation with mucoscopic findings could not be established in our study.

Profile of Dermatological Disorders Among Workers Involved in Fruit Growing Industry of Kashmir Valley in North India.

Introduction: Skin disorders represent a major proportion of occupational disorders. Dermatoses are becoming a source of concern in various population groups. In Kashmir valley, a large number of people are associated directly or indirectly with horticulture. Fruit cultivation is the main occupation of around 33 lakh people in the Union Territory. Aim: To study the profile of dermatological disorders in workers involved in fruit growing industry of Kashmir valley. Materials and Methods: This study was a cross-sectional observational study, carried out over a period of 2 years, in which 701 workers of fruit growing industry of Kashmir valley were screened. Results: 276 (39.37%) of these workers were found to have skin lesions while the rest, that is, 425 (60.63%) were not found to have any dermatoses. Out of the total dermatological lesions observed, occupational dermatoses contributed to 94 cases (34.05%), while non-occupational dermatoses accounted for 182 cases (65.94%). Among the occupational dermatoses, friction-related disorders (callosities and cuts) were predominant (15.9%) followed by allergic (12%) and irritant contact dermatitis (6.2%). Out of the non-occupational dermatoses group, the major portion was comprised by polymorphic light eruption (6.2%) in non-infectious type while in infectious type, onychomycoses predominated (3.3%). Conclusion: Dermatological conditions form a major group of occupational dermatoses among workers involved in fruit cultivation.

Carbon Dioxide Laser Plus Topical 5% Luliconazole: A Better Combination Therapeutic Modality for Onychomycosis.

BACKGROUND: Onychomycosis has always been a therapeutic challenge because of longer treatment duration, potential adverse effects of oral antifungals, and limited efficacy of topical agents. During the past few years, the emergence of laser therapy has been the topic of discussion as a newer, safe, minimally invasive modality of treatment. AIM: The aim of this study was to evaluate the role of fractional CO2 laser and topical luliconazole 5% lotion in the treatment of onychomycosis, as a combined treatment and as independent modalities. MATERIALS AND METHODS: This was a prospective, randomized, triple-limb comparative observational study in which 106 patients with KOH and culture-proven onychomycosis were randomly assigned to three groups. Group A received fractional CO2 laser (10,600nm) triweekly for four sessions (0, 3, 9, and 12 weeks) plus topical luliconazole 5.0% lotion applied twice daily on the affected nail plates and nail folds for 12 weeks. Group B received only fractional CO2 with the same frequency of sessions and laser parameters as in group A. Group C received only topical luliconazole 5.0% solution twice daily for 12 weeks. Treatment outcome was evaluated using onychomycosis severity index (OSI) score, mycological parameters, and level of satisfaction of patients. RESULTS: The degree of clinical improvement, mycological cure, and patient's satisfaction was significantly better in the combined group than individual modalities. There were no severe adverse effects that warranted the discontinuation of the treatment in any of these patients. CONCLUSION: Fractional CO2 laser combined with topical luliconazole 5% lotion is a safe and effective treatment for onychomycosis especially in those who have contraindications to oral antifungals.

Role of Intralesional Vitamin D3 in the Treatment of Cutaneous Warts.

Background: Cutaneous warts are common benign skin lesions caused by human papillomavirus. Various treatment options are available for these but immunotherapy is becoming more and more popular over the past few years. It stimulates cell-mediated immunity causing clearance of warts. Aims and Objectives: The aim is to determine the role of intralesional vitamin D3 in the treatment of warts. Materials and Methods: Consecutive patients with verruca vulgaris attending OPD were included. Around two to three warts were injected first with 0.2 mL of lignocaine (20 mg/mL). After a few minutes, the same warts were injected with 0.2 mL (4 U) of vitamin D3 (15 mg/mL). The injections were given2 weeks apart for a maximum of six sessions, and the patient was followed up 3 months after the last injection. Results: A total of 41 patients of cutaneous warts completed the study. Complete clearance was seen in 27 (65.85%) patients, partial response was seen in 11 (26.83%) patients, and three patients (7.32%) showed no response at all. The mean number of injections required for complete response was four. Recurrence was seen in two patients (4.88%) and one patient had keloid formation at the sight of injection. Limitation: This is a small sample sized study and lacks a control group. Conclusion: Intralesional vitamin D3 is an effective treatment option for common warts.

Pattern of Skin Diseases and Occupational Dermatoses among Paddy Field Workers in Kashmir Valley: A Cross-Sectional Study from North India.

INTRODUCTION: Paddy farming is one of the main occupations in Kashmir valley. The workers associated with paddy are exposed to variety of irritants such as manures, fertilizers, and pesticides, besides getting exposed to intense sunlight for long hours due to the nature of their work. All these factors can potentially either trigger skin diseases or can worsen them. AIM: The aim of this study was to find out the prevalence and pattern of various skin disorders among paddy field workers in Kashmir valley. MATERIALS AND METHODS: This was a cross-sectional descriptive study in which 600 workers engaged in paddy farming in different areas of Kashmir valley were screened. The diagnosis was made on clinical grounds and wherever deemed necessary, relevant investigations were carried out to establish the nature of the disease. RESULTS: A total of 600 workers were evaluated for the presence of skin disorders. Two hundred thirty workers (38.3%) were found to have skin lesions, while the rest, i.e. 370 (61.7%) were free from any skin problem. Out of the total skin lesions, infectious ones were seen in 40.4%, while non-infectious accounted for 59.6% cases. The main non-infectious disorders included melasma, followed by hand and foot eczemas, hyperkeratosis of palms and soles and callosities/cuts, while among the infectious group the major chunk was formed by bacterial infections followed by fungal, viral, and parasitic. Pitted keratolysis and intertrigo were the most common bacterial and fungal infections respectively. CONCLUSION: A large number of skin diseases were seen in paddy field workers, with some diseases showing an occupational nature.

Intra-individual Right-Left Comparative Study of Combined Therapy of Intramatricial Triamcinolone and Platelet-Rich Plasma vs. Intramatricial Triamcinolone Only in Lichen Planus-Associated Nail Dystrophy.

BACKGROUND: While intramatricial triamcinolone is the most commonly used treatment option for onychodystrophy due to lichen planus, the role of platelet-rich plasma (PRP) in the treatment of onychodystrophy is not established. So we combined the two treatment modalities to assess the synergistic action on nail dystrophy. AIMS AND OBJECTIVES: The aim of this article is to compare the effect of combination of intramatricial triamcinolone and PRP vs. intramatricial triamcinolone alone in the treatment of onychodystrophy. MATERIALS AND METHODS: This study was done in 26 and 25 pairs of symmetrical dystrophic nails in hands and feet, respectively. The patients received intramatricial injection of triamcinolone and PRP on one side of finger and toe nails and triamcinolone on the contralateral side. RESULTS: Statistically significant improvements in grades of dystrophy according to the Nail Dystrophy Grading System (NDGS) in the finger and toe nails treated with combined therapy were obtained (P < 0.001 and = 0.002, respectively). According to the physician global assessment, response to combination therapy was statistically significant between the two comparison groups of finger and toe nails (P = 0.001 and = 0.004, respectively). Similarly, according to the patient satisfaction score, statistically significant difference was found between the comparison groups of combination therapy and single therapy (P < 0.001). CONCLUSION: Addition of PRP significantly improved the nail quality. Intramatricial PRP is a safe and effective therapeutic modality in refractory nail dystrophies.

Pediatric Cutaneous Leishmaniasis: A Clinico-Epidemiological Study from North India.

BACKGROUND: There has been an upsurge in the cases of cutaneous leishmaniasis over the past few years in the pediatric population of Jammu and Kashmir, hitherto a nonendemic area for the disease., The aim of this study was to describe the clinico-epidemiological profile and therapeutic outcome of pediatric cutaneous leishmaniasis (PCL) over a 10-year period in J and K. MATERIALS AND METHODS: An observational study was conducted at two tertiary care hospitals of Jammu and Kashmir over a period of 10 years (July 2010-June 20). Children presenting to the outpatient department with lesions suggestive of CL were enrolled. Patients suspected of having CL based on clinical criteria were subjected to slit skin smears (SSS) and histopathological examination (HPE) for validation of the diagnosis. Intralesional or systemic sodium stibogluconate (SSG) was the treatment modality used for the management of patients. Clinical follow-up was done at intervals of 2 weeks for the first 2 months and monthly thereafter. RESULTS: A total of 376 cases of CL in children aged 1.5-15 years (mean age 8.4 ± 1.4 years) were included in the study. The duration of the disease ranged from 8 to 52 weeks (mean 22.52 ± 1.5 weeks). Lesions were noted mainly on exposed parts of the body, with face being the most commonly affected site (89.0%). Nodulo-ulcerative plaques were the predominant clinical presentation (62.76%). The diagnosis was confirmed by the demonstration of Leishman Donovan (LD) bodies in 54.25% on SSS- and 25.79% on hematoxylin and eosin -stained tissue sections. In cases where diagnosis could not be confirmed by demonstration of LD body, a histological pattern conforming to CL and response to a therapeutic trial of SSG provided evidence of leishmanial infection. Complete healing was achieved in 95.02% of the cases at the end of treatment. CONCLUSION: CL is an emerging health problem in the pediatric population of Jammu and Kashmir. Awareness among pediatric health workers regarding this disease and recognition among the differential diagnosis of ulcerated papules or plaques in the pediatric population is imperative.

Clinical and epidemiological study of cutaneous leishmaniasis in two tertiary care hospitals of Jammu and Kashmir: An emerging disease in North India.

BACKGROUND: An increasing number of patients with cutaneous leishmaniasis (CL) are reporting to tertiary care centers in Jammu and Kashmir, an area that has previously been non-endemic for this disease. This merits consideration of CL as a major health problem of considerable epidemiological importance. The aims of this study were firstly to describe the clinico-epidemiological profile, therapeutic characteristics, and outcomes of patients with CL and secondly to highlight this union territory as a new focus of endemicity for CL. METHODS: A two-center hospital-based prospective cohort study was conducted at two tertiary care hospitals in Jammu and Kashmir over a period of 10 years (July 2009 to June 19). All patients presenting to the outpatient departments with lesions suggestive of CL were enrolled for the purpose of this study. Demographic data were recorded on a proforma questionnaire, along with a detailed history and the results of a meticulous examination. Patients diagnosed with CL based on clinical criteria were subjected to slit skin smear (SSS) and histopathological examination for confirmation of the diagnosis. An intralesional pentavalent antimonial, sodium stibogluconate (SSG), was administered at a dose of 0.5 mL/cm2 (100 mg/mL solution) three times weekly to those patients with smaller lesions, and intravenously or intramuscularly at a dose of 20 mg/kg/day to those with larger lesions. The response to treatment was assessed by total re-epithelialization of the lesion and an absence of infiltration and erythema, with or without scarring. Treatment was given until complete resolution of the lesions or for a maximum duration of 10 weeks when given intralesionally and 3 weeks when given systemically. Clinical follow-up was performed twice weekly for the first 2 months and monthly thereafter. The final response to treatment was assessed at 6 months. RESULTS: The study included a total of 1300 patients with a mean age of 26.7 ± 18.5 years. The mean duration of the disease was 28.52 ± 13.5 weeks, ranging from 8 to 64 weeks. Lesions were noted mainly on exposed parts of the body, with the face being the most commonly affected site (89.00%). Nodulo-ulcerative plaques were the predominant lesion type observed (73.92%). The presence of Leishman-Donovan bodies could be demonstrated on SSS and histopathology in 60.69% and 39.54% of patients, respectively. The presence of a recognizable histological pattern conforming to CL and a response to a therapeutic trial of SSG was considered to be confirmatory in the remaining patients. Complete cure was achieved in 84.23% of cases during the study period. Single lesions were more likely to respond to treatment as compared to multiple lesions. The route of administration did not have any significant impact on the final outcome. CONCLUSIONS: With the disease showing an escalating trend in Jammu and Kashmir, the possibility of a new focus of endemicity and its impact on public health need to be contemplated, and appropriate measures should be initiated to contain its spread.
