    Abstract Fusiliers of the family Caesionidae comprise a group of Indo-Pacific reef fishes important in the live bait and artisanal fisheries in many parts of its range, particularly in the Indian Ocean region. Using newly generated mitochondrial COI sequences of 10 species of caesionid fishes from the Laccadive archipelago, we carried out a molecular phylogenetic analysis, which has helped improve our understanding of the diversity, distribution, and systematics of this poorly known group of fishes. The two speciose genera within Caesionidae, Caesio and Pterocaesio, were revealed to be paraphyletic, and as a result, four names earlier considered as subgenera within Caesionidae (Flavicaesio, Odontonectes, Pisinnicaesio, and Squamosicaesio) were elevated to the status of distinct genera. We also discovered the presence of a new lineage in the Central Indian Ocean, sister to Caesio caerulaurea and Caesio xanthalytos, but distinct from both in several morphological characters and a genetic distance of between 2% and 3% in the mitochondrial COI gene. We describe this lineage as Caesio idreesi, a new species, with a distribution spanning the Laccadive Sea and the Bay of Bengal. Our genetic data also helped confirm the first confirmed records of two species, Pisinnicaesio digramma and Squamosicaesio randalli, from the Central Indian Ocean, and a new distribution record for C. xanthalytos in the Laccadive Sea. Combined, these results have helped bridge key biodiversity knowledge gaps of the family Caesionidae and form an excellent baseline for further investigations on their taxonomy, systematics, and life history.

    Abstract The One Health concept recognizes that the health of people is connected to the health of animals and the environment. A 21-year-old female patient presented with several nodular and cystic swellings on the front and sides of her neck for the past 2 years. Histopathology showed sulfur granules surrounded by neutrophils in an area of granulation tissue with filamentous Gram-negative bacilli in the granules. She was a regular cattle handler since her childhood, and one of her cows on the farm had died from a similar sort of illness 2 years back at the same period when her disease began. We made a provisional diagnosis of actinobacillus infection and started the patient on doxycycline 100 mg twice daily. With this treatment, the patient showed an excellent clinical response and her condition healed with resultant scarring within 7 weeks of treatment.

    Abstract The purpose of this study is to relate the distribution and diversity of organisms found in association with plastic debris from South Andaman intertidal ecosystem using several statistical functions. In this study, ten different sites at South Andaman Island were examined for six months for plastic debris of various shape, size and colour along with the concerned organism. A total of 34 species of fauna and 17 species of flora are found associated with the plastic debris from this study. The most common ones are Arthropods, Bryozoans, Annelids and Rhodophyta. Few rare ones are sea anemones- Anthopleura handi and Actinia equina which were also seen attached on hard plastic objects. Diversity analysis highlighted the species evenness and diversity of Mazar Pahad to be maximum and species richness of Brookshabad to be the highest. No correlation was seen between the colour of plastic and the associated organism. Barnacle, Spirorbis and Sea Anemone prefer hard-rigid plastic fragments, whereas Bryozoans prefer a flexible, smooth surface. Lepas, on the other hand, preferred bottle caps, rubber material, and ropes. Many polychaetes were found in almost all the stations indicating that the coast and the water are quite polluted. Correlation between debris size and the number of taxa group showed stochastic phenomenon. Positive correlation was seen among the colony size of taxa group in relation with the exposed area of the debris. In terms of the distribution of plastic debris across the various zones of the intertidal region and the preference of the specific flora or fauna groups, no general trends or pattern was observed. Through this study, it is understood that plastic in one way provides shelter to certain organisms but at the same time harms other organisms through invasion as well as by providing an unnatural habitat.

    Abstract The present review provides a comprehensive account of coral-reef associated fishes around the waters of the Indian subcontinent. The review highlights fishes from coral reefs of the Northern Indian Ocean, particularly from Andaman and Nicobar Island, Lakshadweep Islands, Kerala, and Tamil Nadu coasts. The basis of this review is the compilation of results on the occurrence of fishes from varied pieces of literature obtained for these sites. This article lists various families under the Order Pisces, highlighting their abundance in various locations in Indian waters. A total of 2,810 species were recorded from 176 families covering the above locations of Indian waters. Pomacentridae (160) is the family with more species among the reef fishes, while various species in the family Carangidae (115) showed consistent occurrence in all the sites. Diversity indices are high in Andaman and Nicobar Islands except for species evenness, which was high in one site from Tamil Nadu, the southeast coast of India. Similarity dendrogram showed a high degree of similarity between the two island ecosystems, and the dominance plot revealed a higher relative dominance in Andaman and Nicobar Island. Species abundance plot shows similarity in fish assemblage in reefs of island ecosystems. This review aims to furnish a list of various families of reef-associated fishes and compile data on diversity, distribution, dominance, and abundance within different coral reef systems on the Indian coast. This work is a pioneering effort for creating a complete overview of the reef fishes of the Indian Ocean for future references.

    Abstract Background: Atopic dermatitis (AD) is a chronic, relapsing inflammatory skin disease. Hanifin and Rajka's criteria is the most common diagnostic criteria used for the clinical diagnosis of this condition. However, many find that it is too exhaustive to be used in routine practice, and the specificity of many of the minor criteria poses challenges, particularly from Asian countries with type III, IV, and V skin.
    Aims and objectives: The aim of the study is to evaluate the effectiveness of the minor features of the Hanifin and Rajka criteria for AD in comparison to the UK working party's diagnostic criteria in pediatric populations of India.
    Methodology: A hospital-based cross-sectional study of 100 patients in the pediatric age group (3 months-12 years) with AD was conducted based on history, clinical, and laboratory evaluation. An age-matched control group of 100 pediatric patients who did not have a personal or family history of atopic dermatitis was included after obtaining informed consent to find out the prevalence of minor criteria among the control group.
    Results: Mean of the number of minor clinical criteria found positive in our study population in the infantile and toddler (below 2 years) and childhood groups (2-12 years) was (4.72 ± 1.75) and (5.67 ± 1.78), respectively. Early-onset of disease was the most consistent feature among the minor criteria found in 83% of patients, followed by xerosis (71%), hyperlinearity of palm (56%), pityriasis alba (54%), Denny Morgan fold (52%), elevated serum IgE (47%), perifollicular accentuation (37%), and tendency toward cutaneous infections (37%).
    Conclusion: We found that though some of the minor criteria are highly sensitive and specific to the diagnosis of AD (xerosis, ichthyosis, palmar hyperlinearity, tendency of cutaneous infections, Dennie-Morgan infraorbital fold, pityriasis alba, and perifollicular accentuation), some other criteria were either very rare or nonspecific for AD. We suggest that many of the minor criteria of Hanifin and Rajka may not have much significance for Indian patients and a multicentric nationwide study with a larger patient pool is required to create a trimmed and improved version of Hanifin and Rajka criteria.

    Abstract Juvenile xanthogranuloma (JXG) is the most common form of non-Langerhans cell histiocytic lesion, characterized by benign, usually asymptomatic, self-healing yellowish brown papulonodular lesions of skin and other organs in the absence of metabolic disorder. The cells of origin of JXG are dermal dendrocytic cells. Histopathologically there is dermal infiltration of foamy or non-foamy histiocytes with or without giant cell. Immunohistochemistry shows CD68 positivity with CD1a and S-100 negativity of lesional cells although S-100-positive JXG have been reported. JXG may be associated with neurofibromatosis type one (NF 1) with increased risk of juvenile chronic myelogenous leukemia and other hematological malignancies. Our case was S-100 immunoreactive multiple, cutaneous JXGs with NF 1 without any visceral involvement or malignant complication. We are presenting this case due to its rarity.

    Abstract Background: There are very little elaborative studies in India about various patterns of skin diseases and various factors those influence the diseases in a tertiary institution.
    Aims: To find out the various patterns of skin diseases in relation to age, sex, occupation, and socio-economic status. To find out the magnitude of skin diseases and compare with other similar studies.
    Materials and methods: Collection of data of all new skin cases in a specified period of one year and put on proforma for diagnosis. Few investigations were done for correct diagnosis.
    Results: It was found that skin OPD patients (new) were 4.16% of total new OPD patients, and male female ratio was 1.1:1. Among all patients (12910), infection was commonest (39.54%), followed by allergic skin disorder (29.20%). 25.05% patients were housewives, followed by students (23.21%). Study showed that 33.28% patients had per capita income of ` 361-720/month, and 22.35% patients were educated and/or studied up to class V.
    Conclusion: Pattern of skin diseases are mostly depend not only on environmental factors but also on occupation, socio-economic status, literacy, and age of the patients.
