OBJECTIVETo study the modulation effect of pro- and anti-inflammatory cytokines following long term use of water soluble ethanol extracts from different organs of Nyctanthes arbortristis (NAT) in mouse model of arthritis.

METHODSArthritis was induced in mice by two injections of Freund's complete adjuvant on days 0 and 12 in the sub-planter surface of the right hind paw.

RESULTSInjection of adjuvant resulted in a maximum primary edema of the footpad with erythema, and edema and distortion of joints of the right hind paw after 24-48 hours. Second injection of FCA led to the formation of secondary swellings persisting more than four weeks that spread onto the other hind limb but to a lesser extent. Histological analysis of the ankle on day 47 showed marked evidence of cartilage destruction in association with pannus formation and moderate bone resorption. Proinflammatory cytokine levels in the inflamed joint homogenate were elevated on days 2, 14, and 47. Oral administration of leaf and fruit extracts in arthritic mice reduced joint homogenate levels of tumor necrosis factor-alpha, interleukin-1beta, and interleukin-6 on days 2, 14, and 47 in comparison to untreated arthritic mice. Interleukin-10 level was elevated in the inflamed joint on days 2, 14, and 47 in comparisons to untreated arthritic mice.

CONCLUSIONEvidence of lesser inflammation of the footpad and joint and associated histological observation support the therapeutic benefit of leaf and fruit extracts from Nyctanthes arbortristis. This study helps in understanding the mechanism of anti-inflammatory action of Nyctanthes arbortristis in the light of pro- and anti-inflammatory cytokine balance.

A 31-year-old Indian female with a history of near-total thyroidectomy 2.5-years prior presented with recurrent neck swelling. Magnetic resonance imaging (MRI) of the neck revealed an infiltrating mass involving the thyroid bed. Biopsy from the mass and review of slides from the previous thyroidectomy revealed a spindle cell tumour with interspersed areas of fibrosis and infiltrative edges entrapping thyroid follicles. Beta-catenin immunopositivity and CTNNB1 mutation confirmed the diagnosis of fibromatosis. The case is being reported for its rarity and the discussion of its differential diagnoses.

A 35-year-old female presented with abdominal pain, fever, projectile vomiting, and a diffuse tender epigastric mass. She was diagnosed to have acute persistent pancreatitis with a pancreatic pseudocyst. Elevated serum calcium levels provided an etiologic link between hypercalcemia and pancreatitis. On examination, a nodule was found in the left side of her neck which was later diagnosed as a giant left inferior parathyroid adenoma. This report highlights the critical analysis of history, examination, and investigations to reach an ultimate diagnosis. Pseudocyst drainage and parathyroidectomy resolved her symptoms.
