Kimura Disease in an Adult Indian Female, A Rare Presentation: A Novel Treatment with a Review of Literature.

Kimura disease (KD) is a chronic inflammatory disorder, which is quite rare and has an unclear and much debated etiology. KD is characterized by painless, nodular, subcutaneous swellings along with lymphadenopathy, encountered in the head and neck region more often. It is also known to affect major salivary glands. It is also associated with elevated Immunoglobulins (IgE) and peripheral blood and tissue eosinophilia. Kimura disease generally affects young Asian males. There is considerable difficulty in arriving at clinical diagnosis and often it is frustrating to both patients and the treating physicians because of the difficulty in its management. We are presenting and reporting a case of Kimura disease in a young adult Indian female patient who presented with a swelling in the left parotid region. We have successfully managed this patient medically with a unique combination of drugs, most of which have already been tried and reported in literature by various authors.

Synthesis and biological evaluation of novel 2-alkoxycarbonylallylester phosphonium derivatives as potential anticancer agents.

Several phosphonium derivatives have been synthesized from Baylis-Hillman (BH) reaction derived allyl bromides and aryl phosphines as mitochondria targeting anticancer agents. In vitro cell proliferation inhibition studies on various solid tumor cell lines indicate that most of the compounds exhibit IC50 values in µM concentrations. Further studies reveal that ß-substituted BH bromide derived phosphonium derivatives enhance the biological activity to low µM IC50 values. In vitrometabolic studies show that the lead candidate compound 16 inhibits the production of mitochondrial ATP, increases the proton leak within the mitochondrial membrane and abolishes the spare respiratory capacity in a concentration dependent manner.

Salvage Surgery in Recurrent Oral Squamous Cell Carcinoma.

More than half of patients with oral cancer recur even after multimodality treatment and recurrent oral cancers carry a poorer prognosis when compared to other sites of head and neck. The best survival outcome in a recurrent setting is achieved by salvage surgery; however, objective criteria to select an ideal candidate for salvage surgery is difficult to frame, as the outcome depends on various treatment-, tumor-, and patient-related factors. The following is summarizes various tumor- and treatment-related factors that guide our decision-making to optimize oncologic and functional outcomes in surgical salvage for recurrent oral cancers. Short disease-free interval, advanced tumor stage (recurrent and primary), extracapsular spread and positive tumor margins in a recurrent tumor, regional recurrence, and multimodality treatment of primary tumor all portend worse outcomes after surgical salvage. Quality of life after surgical intervention has shown improvement over 1 year with a drastic drop in pain scores. Various trials are underway evaluating the combination of immunotherapy and surgical salvage in recurrent head and neck tumors, including oral cavity, which may widen our indications for salvage surgery with improved survival and preserved organ function.

Thyroid Hemiagenesis and Papillary Carcinoma: a Rare Association.

A 20-year-old female presented with a slowly growing solitary left thyroid nodule for 1 year. USG and CECT neck showed a 4 × 3 cm solid-cystic nodule in the left lobe of thyroid, with notable absence of the right lobe. FNAC from the nodule was Bethesda V. Operative findings confirmed right thyroid lobe agenesis with corresponding absence of right superior thyroid vessels. The right sided RLN, ESBLN, superior and inferior parathyroids, and inferior thyroid vasculature were in their anatomical positions. She underwent standard left hemithyroidectomy. Histopathological examination revealed follicular variant of papillary carcinoma.
