An Institution Based Cross-Sectional Observational Aetiological Study Correlating the Clinico-Pathological Findings in Patients Presenting with Acquired Palmoplantar Keratoderma.

Background: Palmoplantar keratoderma (PPK) is a heterogeneous group of hereditary or acquired disorders characterised by excessive epidermal thickening of the palms and soles. Proper knowledge about the aetiology of the disease and clinico-demographic profile helps in planning management and predicting outcomes. Aims and Objective: To determine the prevalence of different dermatoses and describe their clinico-histological correlation in acquired palmoplantar keratoderma. Materials and Methods: An institution-based cross-sectional study conducted after obtaining Ethics-Committee permission and consent from participants. Patients of any age or gender presenting with acquired PPK were recruited. The calculated sample size was 67 by using the prevalence rate (p) of 22.2%, allowable error (L) of 10%, the confidence level of 95% (z = 1.96), and an infinite population size of 20,000. Patients were evaluated by taking demographic and clinical data in a pre-designed case record form, necessary laboratory investigations and histopathological examination that wereevaluated by three blinded experts. The pooled data were analysed with statistical software. Results: Among the 67 participants, Psoriasis was diagnosed clinically in 39 (58.2%) and histologically in 7 (10.4%), Lichen planus (LP) clinically in 16 (23.9%) and histologically in 9 (13.4%), Pityriasis rubra pilaris (PRP) in 8 (11.9%) patients clinically and 7 (10.4%) histologically and Hyperkeratotic eczema (HKE) in 4 (6%) clinically and 43 (64.2%) histopathologically. There was very poor inter-rater agreement (Kappa = 0.148, SE 0.0047, 95% CI 0.057 to 0.24). The clinico-pathological correlation was found to be agreeable in 17.9% Psoriasis, 56.2% LP and 87.5% PRP. HKE was commonly misdiagnosed as Psoriasis in 65.1% of patients. Conclusion: Hyperkeratotic lesions of the palm and sole often present with overlapping clinical features and a skin biopsy has to be done to aid in diagnosis. Limitation: Stratification of the clinical expertise of clinicians was done during the analysis.

A Clinico-Demographic Profile and Sexual Behaviour Pattern in Attendees of Designated STI/RTI Clinic Having Sexually Transmitted Infections with Special Reference to HIV Seropositivity.

Introduction: The dynamics of sexually transmitted infections (STIs) are influenced by sexual behaviour (age of first sexual exposure, number of sexual partner/s, sexual orientation, mode of intercourse, addiction, occupation, correct and consistent use of condom). The presence of the human immunodeficiency virus (HIV) influences the clinical pattern of STIs and the course of disease too. Objective: Our study was conducted to find the prevalence of STIs among attendees of a designated STI/RTI clinic (DSRC) with the description of clinico-demographic profile and sexual behaviour and association of HIV seropositivity with STIs. Methods: Ours was an institution-based cross-sectional study conducted at DSRC after obtaining ethics committee approval and consent from patients. Clinical diagnosis, demographic profile and sexual history were obtained after maintaining audio-visual privacy. Statistical Analysis: Medcalc, version 10.2 was used. Results: Among 167 patients attending DSRC during the study period, 76 having sexual dysfunctions were excluded. The major STIs diagnosed were primary syphilis (6.59%), secondary syphilis (2.2%), herpes genitalis (42.86%), condyloma acuminata (26.37%), molluscum contagiosum (5.49%), genital candidiasis (7.69%), bowenoid papulosis (3.3%), genital scabies (4.4%) and chancroid (1.1%). Sexual orientations were heterosexual (64.83%), lesbian (1.1%), gay (12.1%), bisexual (17.58%) and with an animal partner (4.4%). Among the total study population, 8.8% was rapid plasma reagin (RPR) reactive and 12.1% was Integrated Counselling and Testing Centre (ICTC) reactive. Among the total patients who used condoms (n = 49), only 15 (16.4% of total participants) used condoms correctly and consistently. Peno-vaginal mode of intercourse (n = 78) was found to be most common followed by oro-insertive (n = 42), oro-receptive (n = 34), ano-insertive (n = 24), ano-receptive (n = 17) and digital insertion (n = 20). Conclusion: Sexual behaviour influences the disease outcome in patients with reproductive tract infection (RTI)/STI.

Patterns and Trends of Tribal Leprosy: An Overview from a Tertiary Care Leprosy Clinic of Choto Nagpur Plateau of Eastern India.

Background: Leprosy is a chronic granulomatous disease mainly affecting the peripheral nerves and skin. Any communities including the tribals are susceptible to leprosy. Very few studies on clinico-epidemiological patterns of leprosy have been reported in the tribal population, especially in the Choto Nagpur plateau. Aims: To observe clinical types of newly diagnosed leprosy cases among the tribal population and demonstrate bacteriological index, frequency of deformity, and lepra reaction at presentation. Methods: An institution-based cross-sectional study was conducted with consecutive newly diagnosed tribal leprosy patients attending the leprosy clinic of a tribal-based tertiary care center of Choto Nagpur plateau of eastern India, from January 2015 to December 2019. Thorough history taking and clinical examination were done. A slit skin smear for AFB was performed to demonstrate the bacteriological index. Results: There was a steady rise in total leprosy cases from 2015 to 2019. Borderline tuberculoid (BT) was the commonest form of leprosy (64.83%). Pure neuritic leprosy was not uncommon (16.26%). Multibacillary leprosy was noted in 74.72% of cases and childhood leprosy was observed in 6.70% of cases. The commonest nerve involved was the ulnar nerve. Garde II deformity was noted in around 20% of cases. AFB positivity was observed in 13.73% of cases. A high bacteriological index (BI ≥3) was noted in 10.65% of cases. Lepra reaction was observed in 25.38% of cases. Conclusion: BT leprosy, pure neuritic leprosy, childhood leprosy, grade II deformity, and higher AFB positivity were prevalent in this study. The tribal population required special attention and care for the prevention of leprosy amongst them.

BCG vaccination: Effects on the patterns of pediatric leprosy.

INTRODUCTION: Leprosy in pediatric population continues to remain as one of the major public health problems in India. BCG vaccination has been implicated in producing some protection against leprosy. OBJECTIVES: The present study intended to find out the patterns of leprosy in the pediatric age group (<12 years) and to determine the proportion of paucibacillary (PB) and multibacillary (MB) leprosy cases among the BCG-vaccinated and nonvaccinated groups. METHODOLOGY: It is a cross-sectional study among patients with leprosy up to the age of 12 years attending a tertiary care hospital in Eastern India by comprehensive history taking and through clinical examination. The history of BCG vaccination was enquired and the BCG scar was looked for to determine the BCG-vaccinated and nonvaccinated group. After collecting the data in a predesigned case sheet, the data were analyzed. RESULT: Of the 137 patients included in this study, 71.53% belonged to the 11-12 years age, 27.74% the 5-10 years age, and 1 patient the <5 year age group. The sex ratio was 1:1.63. PB leprosy was more common than MB leprosy. Smear positivity, deformity, and reaction were not very frequent. Among the vaccinated patients, the ratio of PB and MB leprosy was 5.3:1, while in the nonvaccinated group the ratio was 1.2:1. Data analysis showed that the proportion of MB leprosy was statistically significant in the nonvaccinated group than in the vaccinated group (p = 0.0352). CONCLUSION: Our study pointed that BCG vaccination might have a role in enhancing the cell-mediated immunity (CMI).

Clinico-Etiological Evaluation of Chronic Leg Ulcer in a Tertiary Care Center of Eastern India.

BACKGROUND: A chronic leg ulcer (CLU) is a significant public health problem. It has various etiologies. Racial, familial, occupational, and social factors may also have an impact on the prevalence of different causes of leg ulcers. Though there are western data on the epidemiology of leg ulcer, similar data are largely unavailable from our part of the world. AIMS: We undertook a study in a tertiary care center in eastern India to determine the clinical and etiological pattern of patients with CLU. MATERIALS AND METHODS: Hundred consecutive patients presenting with CLU, fulfilling the criteria, were included after informed consent. Patients were subjected to proper history taking, clinical examination, routine blood test, and pus for culture and sensitivity test (where needed) along with Ankle Brachial Index (ABI). RESULTS: Among the 100 patients, venous ulcer (34%) was predominant followed by arterial ulcer (14%), mixed arterial and venous ulcer (11%). History of smoking (56%) and obesity (BMI >25) (32%) were the common risk factors in leg ulcer patients. Fifty nine percent of the total CLU were infected and out of this, 86.4% showed growth of microorganisms. Staphylococcus aureus (39%) was the most commonly isolated organism, followed by Pseudomonas aeruginosa (15%). Eleven (24.44%) clinically diagnosed venous ulcer patients showed significantly lower ABI (<0.9) and were diagnosed as mixed ulcer (a venous ulcer with a peripheral arterial disease). CONCLUSION: Venous ulcer and mixed ulcer are the most common type of CLU.

Clinicopathological Study of Primary Cutaneous Amyloidosis in a Tertiary Care Center of Eastern India Reveals Insignificant Association with Friction, Scrubbing, and Photo-Exposure: How valid is the "Keratinocyte Hypothesis"?

INTRODUCTION: Primary cutaneous amyloidosis (PCA) can be classified into four principal categories: macular amyloidosis, lichen amyloidosis, biphasic, and nodular amyloidosis. Some unusual variants such as widespread diffuse hyperpigmentation without papules, poikiloderma like involvement, lesions following Blaschko's line, etc., have also been reported. However, not much data are available regarding the demography, epidemiology, clinical patterns, and distribution and histopathological findings, especially from the eastern part of India. AIMS: We conducted a cross-sectional, institution-based study to evaluate clinicopathological pattern and factors of PCA in eastern India. MATERIALS AND METHODS: We recorded clinical and histopathological findings of 100 consecutive patients of PCA presenting to a tertiary care institution of Kolkata in eastern India. RESULTS: We found female patients of PCA outnumber male (M:F =1:1.9) with majority of patients being young adults (56%) between 20 and 40 years of age. More than half (54%) of the patients were pruritic. The severity of pruritus is significantly more associated with lichenoid and biphasic variants over macular amyloidosis. Positive family history was recorded in 17% of cases. Macular variant was the most common variant constituting 48% of the total PCA. We also found that the association with history of friction and scrubbing and photo-exposure were statistically insignificant. However, duration of the disease has statistically significant association with the disease morphology. Congo red stain showed these deposits as reddish orange substance in 28 patients out of 64 patients' samples on which Congo red could be performed. CONCLUSION: Our study revealed that many concepts of pathogenesis of PCA including friction and photoexposure might have lesser importance. However, morphological types were significantly associated with the duration of the disease and symptom severity.

Pattern of sexually transmitted infections: A profile from a rural- and tribal-based sexually transmitted infections clinic of a tertiary care hospital of Eastern India.

INTRODUCTION: Prevalence of Sexually transmitted infections (STI's) in developing nations is very high where the measures for STI treatment and prevention are limited. Enormous variation in clinical presentation make STI's very difficult to be studied epidemiologically. To know the exact prevalence of STI's is very important for a region or community for planning preventive strategies. The aim of the present study is to observe the pattern of sexually transmitted infections among the tribal and non-tribal population attending a rural and tribal base tertiary care Centre. METHOD: All the consecutive STI patients irrespective of age and sex attending the STI clinic were included. Thorough clinical examination and relevant investigations were done to know the different STI's present in them. They were divided into tribal and non-tribal group as per history and comparison of patterns of STI's done among the two groups. RESULT: Around 34% of STI patients were tribal. Majority of patients belong to 20-40 years of age. Sex ratio of tribal group was 1:0.86 and non-tribal group was 1:2.64. The difference is statistically significant. Commonest STI in both the group was Genital ulcer disease Herpetic but the occurrence of urethral discharge, genital scabies, and inguinal bubo were among the tribal group. Per vaginal discharge was the commonest STI among the female in both the groups. VDRL positivity was 1.16% and HIV positivity was 0.36% among STI clinic attendees. CONCLUSION: Tribal females need special attention for prevention of STI in tribal community.

Clinico-epidemiological Study of Congenital Ichthyosis in a Tertiary Care Center of Eastern India.

BACKGROUND: Congenital ichthyoses comprises various specific genetic diseases and can range from mild to very severe presentation. Furthermore, these may be associated with various syndromes. There is scanty data regarding the demographic profile and clinical features of patients with congenital ichthyosis in India. AIMS AND OBJECTIVES: The aim is to evaluate the epidemiology and clinical characteristics of various types of congenital ichthyoses. MATERIALS AND METHODS: The study was conducted for 1 year from April 2013 to March 2014. Patients were evaluated for epidemiological profile and clinical features. RESULTS: During the study of 1 year, 106 patients of congenital ichthyoses were identified. The most common of the various ichthyoses was ichthyosis vulgaris, followed by lamellar ichthyosis, X-linked recessive ichthyosis. One case of Netherton syndrome and one of ichthyosis hystrix were also identified. CONCLUSION: Various types of congenital ichthyoses present with different clinical features which range from mild to severe. These present with significant psychological stress to both patients and their families. Furthermore, all these diseases have significant implications of transmission to their offspring.

Levels of oxidative damage and proinflammatory cytokines are enhanced in patients with active vitiligo.

Vitiligo is an autoimmune depigmenting skin disease characterised by loss of melanocytes wherein oxidative stress is proposed to be the initial triggering factor with subsequent immune dysregulation. This study aimed to evaluate the relationship, if any, between the generation of reactive oxygen species (ROS), markers of oxidative damage and circulating cytokines in patients with active vitiligo. The generation of ROS in erythrocytes and neutrophils was significantly higher in patients with active vitiligo than healthy controls. Alongside, markers of oxidative stress-mediated damage namely lipid peroxidation, DNA damage and protein carbonylation were evaluated. Patients with active vitiligo demonstrated increased lipid and DNA damage but minimal protein damage. There was a significant decline in the free radical scavenging capacity of active vitiligo cases. A positive correlation existed between baseline levels of ROS and lipid peroxidation as also DNA damage. Patients with active vitiligo demonstrated an increase in several proinflammatory (IL-6, TNF-α, IL-1ß, IFN-γ and IL-8) and some anti-inflammatory/immunoregulatory (IL-5 and IL-10) cytokines. Importantly, the levels of IFN-γ and IL-10 consistently correlated with the generation of ROS, markers of damage and their free radical scavenging capacity. Taken together, patients with active vitiligo demonstrated an enhanced generation of ROS in erythrocytes and neutrophils which mediated lipid peroxidation, DNA damage and coupled with a decline in their antioxidant capacity created a pro-oxidant milieu that favoured tissue damage and potential generation of neoantigens, accounting for disease progression.

A study of the free radical scavenging effects of Piper betle leaf extract in patients with vitiligo.

BACKGROUND: Vitiligo is an idiopathic skin disease manifested by depigmented macules. It is characterised by melanocyte destruction, and redox imbalance is proposed to play a contributory role. AIM: The aim of this study was to analyze the effects of an ethanolic extract of Piper betle leaves on the generation of reactive oxygen species in erythrocytes sourced from vitiligo patients. METHODS: The effect of Piper betle on the generation of reactive oxygen species in erythrocytes was measured by flow cytometry in patients with active and stable vitiligo versus healthy controls, using 5-(and-6)-chloromethyl-2'-7'-dichlorodihydrofluorescein diacetate. RESULTS: The generation of reactive oxygen species in erythrocytes was higher in patients with vitiligo (n = 23) compared to healthy controls (n = 18). The geometrical mean fluorescence channel was 23.05 ± 2.11 in patients versus 17.77 ± 1.79 in controls, P = 0.039. The levels of reactive oxygen species were higher in patients with active vitiligo. Treatment of erythrocytes with Piper betle in concentrations of 0.5 and 1.0 µg/ml significantly decreased the baseline levels of reactive oxygen species by 31.7% in healthy controls, and 47.6% and 44.3% in patients with active vitiligo, respectively. Piper betle effectively scavenged hydrogen peroxide, which was evident by a decrease in the geometrical mean fluorescence channel by 52.4% and 62.9% in healthy controls, and 45.0% and 57.0% in patients with active vitiligo. LIMITATIONS: The study had a small sample size. Future studies should focus on evaluation of the antioxidant role of Piper betle at the lesional site. CONCLUSION: This pilot study indicates that patients with active vitiligo demonstrate enhanced generation of reactive oxygen species in erythrocytes, which was significantly reduced following ex vivo treatment with Piper betle.

A 5-year Journey with Cutis Laxa in an Indian Child: The De Barsy Syndrome Revisited.

De Barsy syndrome (DBS), synonymously known as autosomal recessive cutis laxa type III, is an extremely rare condition clinically characterized by cutis laxa, a progeroid appearance, and ophthalmologic abnormalities. We present here an account of 5-year follow-up since the birth of an Indian boy with DBS, who had a few rare and unusual manifestations. In addition, our case probably represents the first reported case of DBS from India.
