“…The cardinal symptoms include those of joint and skin diseases. While inflammatory joint disease is a frequent presenting symptom, and is sole symptom in 45% of patients, skin disease is the presenting manifestation in 30% of patients [10]. Arthropathy usually precedes skin lesions (50%); skin lesions may precede disease (25%) or both can occur concurrently (25%) [3].…”

“…The trapping of NPs within topological defect cores allows for the release of the defect core energy and for the stabilization of the composite systems [5][6][7][8][9] . LC topological defects may thus be useful as a matrix for new kinds of NP organizations templated by the defect geometry [10][11][12] . The research on LC topological defects is constantly expanding and many attractive systems are emerging, in particular characterized by the formation of different kinds of topological defects in a single system, like LC droplets or shells [13][14][15][16] or even oriented thin smectic films 17,18 .…”

In this article, we show how advanced hierarchical structures of topological defects in the so-called smectic oily streaks can be used to sequentially transfer their geometrical features to gold nanospheres. We use two kinds of topological defects, 1D dislocations and 2D ribbon-like topological defects. The large trapping efficiency of the smectic dislocation cores not only surpasses that of the elastically distorted zones around the cores but also the one of the 2D ribbon-like topological defect. This enables the formation of a large number of aligned NP chains, within the dislocation cores that can be quasi-fully filled without any significant aggregation outside the cores. When the NP concentration is large enough to entirely fill the dislocation cores, the LC confinement varies from 1D to 2D. We demonstrate that the 2D topological defect cores induce a confinement that leads to planar hexagonal networks of NPs. We then draw the phase diagram driven by NP concentration, associated with the sequential confinements induced by these two kinds of topological defects. Owing to the excellent large-scale order of these defect cores, not only the NP chains but also the NP hexagonal networks can be oriented along the desired direction, suggesting a possible new route for the creation of either 1D or 2D highly anisotropic NP networks. In addition, these results open rich perspectives based on the possible creation of coexisting NP assemblies of different kinds, localized in different confining areas of a same smectic film that would thus interact thanks to their proximity but also would interact via the surrounding soft matter matrix.

This is a rare case report of a thirty-eight-year-old male who presented with multiple asymptomatic hyper-pigmented papulonodular lesions on the face for the past two years without the association of pain or pruritus and with restriction of elbow movements. The diagnosis of multicentric reticulohistiocytosis was made on histopathological findings of Touton type of giant cells and sheets of foamy histiocytes along with immunohistochemistry (IHC) studies. Workup was done for other associated diseases. Multicentric reticulohistiocytosis (MRH) is also known as lipoid dermatitis,1 a rare disease which is characterised by the presence of extensive papulonodular cutaneous eruptions and severe, sometimes destructive arthropathy, followed by eruption of the skin and mucous membrane lesion.2,3 It’s a rare idiopathic nonLangerhans cell histiocytosis.4 This disorder is characterised by predominant cutaneous manifestation and joint involvements. The lesions may show regression and recurrence, many case studies show an association of this lesion with internal malignancies, autoimmune diseases, hyperlipidaemias, and tuberculosis.5,6 Few cases have shown musculoskeletal involvement with features such as myositis. The disease was described initially as reticulocytosis granuloma in 1952 by Caro and Senear, later the term was coined by Goltz and Laymon as multicentric reticulohistiocytosis in 1954.4 It is also known by different names such as giant cell histiocytosis, lipoid dermato-arthritis, lipoid-rheumatism and reticulohistiocytosis granuloma. The disease incidence is very low worldwide, less than 200 cases have been reported in literature5 and reports from India are limited.
