The activity of natural killer (NK) cells can be modified by a number of factors that either increase or suppress cytotoxicity. We have investigated in detail the cytokine induced killing of a NK resistant renal carcinoma cell line Cur by human NK cells. Preincubation of peripheral blood mononuclear cells with interferon alpha (IFN alpha), interleukin 2 (Il-2), interleukin 1 (Il-1) and tumor necrosis factor alpha greatly increased the rate and magnitude of Cur killing. Positively selected CD16 (+) cells were found to respond to cytokine stimulation and to mediate Cur killing. The effects of Il-2 and IFNa could be upregulated by costimulation of effector cells with Il-1 or TNF alpha. It was shown that TNF alpha induced Il-2 receptor expression on CD16(+) cells alone and even more in combination with Il-2. Studies of NK cell function in various rheumatic diseases revealed reduced NK cytotoxicity in peripheral blood and synovial fluid (SF), both in rheumatoid arthritis (RA) and juvenile rheumatoid arthritis (JRA). By contrast, normal NK function was found in patients with ankylosing spondylitis (AS) and psoriatic arthritis. A discordance with regard to the percentage of Leu 7 positive mononuclear cells and NK function in peripheral blood and SF was demonstrated. Minimal expression of Leu 7 positive cells and cytotoxicity was present in synovial membranes. NK function in rheumatic disease was largely independent of drug therapy. Natural killer (NK) cells are a subset of lymphocytes that mediate spontaneous cytotoxicity against certain tumor and virus infected cells without any known prior sensitation.(ABSTRACT TRUNCATED AT 250 WORDS)

Amyloidosis is a systemic disorder characterized by the extracellular tissue deposition of insoluble, toxic aggregates in bundles of beta-sheet fibrillar proteins. These deposits are typically identified on the bases of their apple-green birrefringence under a polarized light microscope after staining with Congo red, and by the presence of rigid, nonbranching fibrils 8 to 10 nm in diameter on electron microscopy. The type of amyloid fibril unit can be further defined by immunohistology or by immunoelectron microscopy. It has been described at least 25 different human protein precursors of amyloid fibrils, which will describe its corresponding amyloid disease. The most common types of amyloidosis are AL (primary) and AA (secondary) types; the former, is the most frequent and is due to deposition of proteins derived from immunoglobulin light chain fragments, occurring alone or in association with multiple myeloma. The later (AA), is caused by deposition of fibrils composed of fragments of the acute phase reactant serum amyloid A (SAA) and complicates chronic diseases with ongoing or recurring inflammation, namely; rheumatoid arthritis (RA), juvenile chronic polyarthritis, ankylosing spondylitis, familial periodic fever syndromes (Familial Mediterranean Fever), chronic infections and furthermore, some neoplasms (mainly renal cell carcinoma and Hodgkin's disease). Despite its less frequent association, some benign neoplasms can subsequently complicate to AA amyloidosis, therefore, an early diagnose and successful treatment may lead indeed, to regression of the amyloid disease. Herein, we present two cases of AA amyloidosis, both of them caused by 2 different benign neoplasms: 1. A 34 year-old woman, after chronic oral contraceptive use, developed an hepatic adenoma (fig. 1) which finally lead to AA amyloidosis with primary kidney presentation (pure nephrotic syndrome) (table 1). Post-surgical complications yield to acute renal failure from which unfortunately could not be recovered. After being on hemodialysis therapy during 10 months she received a first renal allograft without any complication. 2. A 20 year old woman, was diagnosed of AA amyloidosis after a renal biopsy (fig. 2) because of nephrotic syndrome (table 1). Further investigation lead to the finding of a hialyne-vascular type Castleman's disease located in the retroperitoneum (fig. 2). Despite surgical resection and medical treatment (colchicine) she developed progressive renal failure requiring initialization of hemodialysis therapy. After 6 years being on hemodialysis, she received a first renal allograft which is currently functioning after one year of follow- up. Although other chronic inflammatory diseases complicate more frequently to AA amyloidosis, benign tumors have to be taken into account as a potential ethiological cause for secondary amyloidosis.

This case report presents a patient suffering acute fatal intracranial-intratumoral hemorrhage during a gamma knife treatment session. Acute hemorrhage during a radiosurgery session is extremely rare and a plausible cause for this case is discussed along with a literature review of previously reported incidents. The patient was a 71-year-old male presenting with three large intracranial lesions and an underlying primary renal cell carcinoma malignancy. Because of a severe kyphotic deformity resulting from ankylosing spondylitis, the patient was placed in a moderate Trendelenburg position to allow his head to fit into the gamma knife unit during the radiosurgery session. The two left-sided lesions were to be treated with 20 Gy to the 50% isodose line, and the right-sided lesion with 16 Gy to the 40% isodose line. Anesthesia was available throughout the treatment session to aid with pain control. The gamma knife treatment was aborted because the patient suffered a generalized seizure while in the unit. Immediate head CT of the patient revealed large acute hemorrhages into all three intracranial masses. This proved to be a fatal complication. It is likely that this positioning contributed to the hemorrhage. The clinical history of this patient is provided as well as a review of the literature on acute intracranial hemorrhage associated with radiosurgical therapy.

Nonsteroid antiinflammatory drugs have been implicated as nephrotoxic drugs, causing both acute and chronic adverse effects that range from reversible ischemia to chronic kidney disease and urothelial tumors to renal cell carcinoma specially papillary subtype. We report one case of collecting duct (Bellini duct) renal cell carcinoma in patient with analgesic-abuse nephropathy. This young individual was suffering from ankylosing spondylitis since the age of 16 years and was consuming diclofenac and paracetamol (acetaminophen) combination for >15 years. He developed hypertension, secondary glomerulopathy, chronic kidney disease and collecting duct renal cell carcinoma.
