Synthesis of β-hydroxy-1,4-disubstituted-1,2,3-triazoles catalyzed by copper ferrite nanoparticles in tap water using click chemistry

A novel one pot synthesis of β-hydroxy-1,4-disubstituted-1,2,3-triazoles has been developed by using CuFe2O4 magnetic nanoparticles. This methodology involves additive free, easily recyclable catalyst in water medium and avoids the handling of organic azides as they are generated in situ.

Ru-Catalyzed highly site-selective C–H bond arylation of 9-(pyrimidin-2-yl)-9H-carbazole

We describe here an efficient ruthenium-catalyzed C–H bond ortho-arylation of 9-(pyrimidin-2-yl)-9H-carbazole by using boronic acids. This methodology exhibits excellent and high site-selectivity, functional group tolerance and was found to give the desired product in moderate to good yields.

Two Uncommon Paraneoplastic Neurological Syndromes in a Child With Hodgkin Lymphoma.

Paraneoplastic neurological syndromes (PNS) are rare, remote effects of cancer that are usually caused by an altered immune response to the tumor and not due to the tumor mass, metastasis, infection, ischemia, or metabolic derangements. PNSs can affect any area of the central, the peripheral, and the autonomic nervous systems. These are rare in lymphomas compared with solid tumors attributed to their presentation even in late stages and the absence of onconeural antibodies. We present a child with stage IIB Hodgkin lymphoma who presented with dual PNS, achalasia cardia, and Holmes Adie pupil occurring synchronously with the cancer.

Anaplastic large cell lymphoma: a rare cause of extreme neutrophilia in a child

Anaplastic large cell lymphoma (ALCL) in children can present with a broad spectrum of clinical manifestations which apart from nodal and extra nodal disease include paraneoplastic phenomena that can mimic an infection or inflammatory illness leading to delayed diagnosis. The following case report describes a child with prolonged fever, hepatosplenomegaly, polyserositis and extreme neutrophilia masquerading as an infection or inflammatory disorder for long before the definitive diagnosis of ALCL was made. This case highlights the rare paraneoplastic phenomena in ALCL and the heightened need to suspect this disorder when the search for underlying infections and connective tissue disorders are not conclusive.
