Despite the widespread use of non-steroidal anti-inflammatory drugs (NSAIDs), the current number of reported cases of poisoning is small. However, with the introduction of 'over-the-counter' preparations of NSAIDs in some countries (e.g. ibuprofen in the UK and USA) an increased incidence of acute poisoning from this group of drugs can be expected. Conventionally, NSAIDs are divided into the following groups based on their chemical structure: arylpropionic acids, indole and indene acetic acids, heteroarylacetic acids, fenamates, phenylacetic acids, pyrazolones and oxicams. Unless NSAIDs are ingested in substantial overdose, acute poisoning with these agents does not usually result in significant morbidity or mortality. In most cases the clinical features are mild and confined to the gastrointestinal and central nervous systems, though acute renal failure, hepatic dysfunction, respiratory depression, coma, convulsions, cardiovascular collapse and cardiac arrest may complicate severe poisoning. Arylpropionic acid derivatives were thought initially to have a low order of toxicity in overdose but, in addition to anticipated gastrointestinal symptoms, headache, tinnitus, hyperventilation, sinus tachycardia, hypoprothrombinaemia, haematuria, proteinuria and acute renal failure have been described. In addition, drowsiness, coma, nystagmus, diplopia, hypothermia, hypotension, respiratory depression and cardiac arrest have been reported in severe cases of poisoning. Oxyphenbutazone and phenylbutazone are considerably more toxic in overdose. Complications of severe poisoning include coma, convulsions, hepatic dysfunction, acute renal failure, sodium and water retention, haematuria, cardiovascular collapse, respiratory alkalosis, metabolic acidosis, hypoprothrombinaemia and thrombocytopenia. In contrast, indomethacin appears to be much less toxic. In addition to gastrointestinal symptoms, indomethacin taken in overdose induces headache, tinnitus, dizziness, lethargy, drowsiness, confusion, disorientation and restlessness. Only 1 case of acute sulindac poisoning has been reported in the literature. A 16-year-old boy was admitted with hypokalaemia (2.2 mmol/L), transient granulocytosis and 'scanty' haematemesis after ingesting 12 g sulindac. No case of acute tolmetin poisoning have been reported. The fenamates (flufenamic acid, meclofenamic acid, mefenamic acid, tolfenamic acid) are, with the exception of mefenamic acid, not as widely prescribed as other groups of NSAIDs. In overdose, mefenamic acid may result in nausea, vomiting, diarrhoea, muscle twitching, convulsions and coma.(ABSTRACT TRUNCATED AT 400 WORDS)

A 68-year-old man who developed MPO-ANCA-associated glomerulonephritis during propylthiouracil (PTU) treatment is reported. In 1986, he was diagnosed as having interstitial pneumonitis. Although he tested positive for antinuclear antibody and rheumatoid factor, he had no symptoms and was followed up without therapy. Five years later, the diagnosis of Graves's disease was made after complaints of body weight loss, diplopia and exophthalmos. Tests showed positivity for anti-thyroid stimulating hormone (TSH) receptor antibody, antithyroidperoxidase antibody and antithyroglobulin antibody. He was treated with PTU and prednisolone for four years. In November 1995, hematuria and proteinuria developed, and renal function deteriorated rapidly. A renal biopsy revealed crescentic glomerulonephritis and the serum titer of MPO-ANCA was markedly elevated. He was treated with a high dose of prednisolone and cyclophosphamide. Although the serum creatinine level gradually decreased, irreversible renal dysfunction persisted. In this patient, the presence of various autoantibodies had been recognized for several years before MPO-ANCA-associated glomerulonephritis developed. Polyclonal B-cell activation and PTU treatment may have played a role in the pathogenesis of MPO-ANCA-associated glomerulonephritis.

A cadaveric kidney transplant recipient, with no history of a connective tissue disease, was admitted with malaise, arthralgias, diplopia, mild headache, and a painful left eye. The patient was on maintenance immunosuppression for 14 years with cyclosporine and methylprednisolone. Initial laboratory data indicated an elevated serum creatinine from baseline, 2+ proteinuria, and 50 to 100 red blood cells (RBCs)/high-power field (HPF) in the urine. Renal biopsy was consistent with necrotizing vasculitis involving glomerular capillaries, with crescent formation and an absence of immune complexes. Perinuclear antineutrophil cytoplasmic autoantibodies (P-ANCA) and anti-myeloperoxidase (MPO) were found to be elevated. To the best of our knowledge, this is the first reported case of an ANCA-associated small vessel vasculitis (SVV) developing in a renal transplant recipient without history of connective tissue disease.

Fibrillary glomerulonephritis (FibGN) is a rare cause of progressive renal dysfunction, often leading to dialysis within a few years. A 60-year-old woman presented with a 2 month history of right-sided retro-orbital pain and recent diplopia. Laboratory testing revealed an altered renal function with increased serum creatinine and mild proteinuria. MRI of the brain revealed the presence of a soft tissue mass on the right cavernous sinus compatible with the diagnosis of Tolosa-Hunt syndrome (THS). Renal biopsy showed a pattern compatible with fibrillary glomerulonephritis. For this reason steroid therapy was initiated at a dose of 1 mg/kg/day and adjusted according to the clinical course. Neurological symptoms regressed shortly after the beginning of therapy and renal function and proteinuria remained stable for the 3 years following the withdrawal of steroid therapy. Percutaneous renal biopsy was again performed and confirmed the previous diagnosis of FibGN in association with other glomerular-lesion-like mesangial widening, thickening of capillary walls and severe arterio-arteriolosclerosis. This case report describes what is believed to first report of the association of FibGN and THS, which both responded to steroid therapy.

Randall disease is an unusual cause of extraocular motor nerve (VI) palsy. A 35-year-old woman was hospitalized for sicca syndrome. The physical examination showed general weakness, weight loss, diplopia related to a left VIth nerve palsy, hypertrophy of the submandibular salivary glands, and peripheral neuropathy. The biological screening revealed renal insufficiency, serum monoclonal kappa light chain immunoglobulin, urinary monoclonal kappa light chain immunoglobulin, albuminuria, and Bence-Jones proteinuria. Bone marrow biopsy revealed medullar plasma cell infiltration. Immunofixation associated with electron microscopy analysis of the salivary glands showed deposits of kappa light chains. Randall disease was diagnosed. The patient received high-dose melphalan followed by autostem cell transplantation which led to rapid remission. Indeed, at the 2-month followup assessment, the submandibular salivary gland hypertrophy and renal insufficiency had disappeared, and the peripheral neuropathy, proteinuria, and serum monoclonal light chain had decreased significantly. The persistent diplopia was treated with nerve decompression surgery of the left extraocular motor nerve. Cranial nerve complications of Randall disease deserve to be recognized.

Preeclampsia can cause myriad organ dysfunction, including cranial nerve palsies that pose diagnostic and management dilemmas. We present an unusual case of third nerve palsy, (presenting as diplopia, ptosis) with hypertension, hyperreflexia, proteinuria, easy bruising in a parturient at 34 + 6/52 weeks of twins gestation. She was treated as for severe preeclampsia and HELLP syndrome; intravenous magnesium sulphate and labetalol commenced and emergent cesarean delivery performed under general anesthesia due to concerns of low platelets and for airway protection should her glascow coma scale (GCS) deteriorate. Postoperatively, stroke, aneurysm and intra-cerebral causes of third nerve palsy were excluded, with subsequent recovery of symptoms upon blood pressure normalization. The eye signs are postulated to be due to two preeclamptic mechanisms involving disordered cerebral autoregulation: (1) hyperperfusion and breakdown of the blood-brain barrier that occurs with rising hypertension, causing fluid/blood product extravasation into brain parenchyma, or (2) focal reactive vasoconstriction and local hypoperfusion, contributed to by endothelial dysfunction.

We report a 76-year-old male with ANCA-associated hypertrophic pachymeningitis, who presented with crescentic glomerulonephritis. At the initial visit, he had episodic frontal headache and multiple cranial nerve palsy, including double vision, right deafness, hoarseness, and dysphagia. Because proteinuria and hematuria were detected on urinalysis, we performed a kidney biopsy, leading to the diagnosis of crescentic glomerulonephritis. The presence of vascular inflammation in the kidney biopsy led us to consider that this patient may show progression to the systemic type of MPO-ANCA-positive hypertrophic pachymeningitis. This proved useful for prognostic and treatment determination. Based on the results of laboratory tests, imaging studies, and biopsies of the dura mater and kidney, the patient was diagnosed with ANCA-associated hypertrophic pachymeningitis.
