Rice-based integrated farming system improves the soil quality, bacterial community structure and system productivity under sub-humid tropical condition.

Rice-based integrated farming system improves the productivity and profitability by recycling resources efficiently. In the sub-humid tropics, rice production without sufficient nutrient replenishment often leads to soil health and fertility degradation. There has been very limited research on soil health and fertility after adopting a multi-enterprising rice-based integrated farming system (IFS), notably in the rice-fish-livestock and agroforestry system, when compared to a conventional farming system (CS). Therefore, the present study analyzed the dynamics of soil properties, soil bacterial community structure and their possible interaction mechanisms, as well as their effect on regulating soil quality and production in IFS, IFSw (water stagnant area of IFS) and CS. The results indicated that soil nutrient dynamics, bacterial diversity indices (Shannon index, Simpson index, Chao 1, ACE and Fisher index) and system productivity were higher in IFSw and IFS compared to CS. Moreover, relative operational taxonomic units of dominant bacterial genera (Chloroflexi, Acidobacteria, Verrucomicrobia, Planctomycetes, Cyanobacteria, Crenarchaeota and Gemmatimonadetes) were also higher in IFSw and IFS compared to CS. Mean soil quality index (SQI) was highest in IFSw (0.780 ± 0.201) followed by IFS (0.770 ± 0.080) and CS (0.595 ± 0.244). Moreover, rice equivalent yields (REY) and rice yields were well correlated with the higher levels of soil biological indices (SQIBiol) in IFS. Overall, our results revealed that rice-based IFS improved the soil health and fertility and ensuing crop productivity through positive interaction with soil bacterial communities and nutrient stoichiometry leading to agroecosystem sustainability.

Waxy papules, infiltrated alopecic plaques, and shin ichthyosis.

A 38-year-old male presented with waxy papules, plaques over the neck and extremities, and ichthyotic scales over the lower limbs. Skin biopsy revealed a dense medium-sized lymphocytic infiltrate in the dermis, with perifollicular accentuation and focal exocytosis into the follicular epithelium with strong positivity for CD 3, 4, and 5. Considering the clinicopathological correlation, a diagnosis of follicular mycosis fungoides (FMF) was made. It is a variant of classic mycosis fungoides (MF) where atypical cells invade the follicular epithelium.

'Generalised Pruritus with Prurigo-Like Lesions and Generalised Lymphadenopathy: Could be an Early Diagnostic Clue for Angioimmunoblastic T-Cell Lymphoma (AITL) and/or Histoplasmosis'.

Angioimmunoblastic T-cell lymphoma (AITL) is an uncommon systemic lymphoproliferative disorder that comprises approximately one-fifth of all mature peripheral T-cell lymphomas. A broad range of cutaneous manifestations include maculopapular, papulovesicular, erythrodermic, urticarial, plaque-like and nodular, and they are mentioned in 50% of patients and may precede systemic symptoms, which include lymphadenopathy, hepatosplenomegaly and constitutional symptoms. Histoplasmosis is a common granulomatous infection worldwide caused by Histoplasma capsulatum, a dimorphic fungus. Cutaneous manifestations are reported to occur in 10% to 25% of immunosuppressed patients with disseminated histoplasmosis. Generalised pruritus as a presenting feature is rarely described in both of these entities. We report a unique case of AITL with histoplasmosis discovered during paraclinical assessment of generalised pruritus (? neurodermatitis) with prurigo-like lesions and lymphadenopathy.
