We report a case of primary diffuse tracheobronchial amyloidosis in a 72-year-old lady who presented with a long history of recurrent cough, dyspnoea, wheezing, haemoptysis and chest infection. She was treated successfully with three sessions of laser therapy. There were improvements in both clinical symptoms and measurements of airway obstruction. Bronchodilators and oral prednisolone were not required after treatment.

Case ReportsCerebral hemorrhage with biopsy-proved amyloid angiopathy.
Clinical, radiological, and immunohistochemical findings in brain biopsy specimens from six patients with cerebral amyloid angiopathy-associated intracerebral hemorrhage were reviewed. Acute clinical presentations included headache, nausea and vomiting, loss of consciousness, and focal neurological deficits such as hemiplegia and blindness. Transient ischemic attacks experienced by one patient and referable to one hemisphere did not indicate impending hemorrhage in that region. ⋯ Immunoreactive senile plaques were few compared with the numbers of stained microvessels. Reactive astrocytes in some patients were labeled by both antiserum samples, suggesting uptake or production of these proteins by the astrocytes. This study demonstrates the heterogeneous clinical and radiological features of cerebral amyloid angiopathy-related brain hemorrhage and the value of anti-A4 and anti-gamma-trace immunohistochemical study of biopsy material from patients with suspected cerebral amyloid angiopathy-related intraparenchymal bleeding.

Case ReportsExcessive hypernatremia in a patient with renal amyloid disease.
A 24-year-old Italian male presented with a nephrotic syndrome in September 1984. In February 1985 renal biopsy showed amyloid disease with tubular atrophy and interstitial fibrosis. Edema was treated with furosemide, and cholchicine was started. ⋯ The fluid deficit was slowly corrected. He was discharged three weeks later with normal serum electrolytes. This case demonstrates that (1) severe hypernatremia can present with mild neurological symptoms and (2) it can be survived provided that it develops slowly and is corrected cautiously.

Cerebral amyloid angiopathy is increasingly recognized as a cause of lobar cerebral hemorrhage in normotensive elderly individuals. Isolated reports have suggested that neurosurgical intervention entails a high risk of precipitated hemorrhage. We identified 16 pathologically confirmed cases of cerebral amyloid angiopathy. ⋯ Recurrent postoperative cerebral hemorrhage was seen in four patients at 2 days, 9 days, 6 weeks, and 10 months, but surgery was thought to have precipitated the cerebral hemorrhage in only one patient. Recurrent cerebral hemorrhage also was seen in two of the eight nonoperated cases. Recurrent cerebral hemorrhage is characteristic of cerebral amyloid angiopathy, but we conclude that neurosurgical intervention, particularly evacuation of hematomas, is not associated with major risk of precipitated hemorrhage.

Case ReportsHemodialysis-associated amyloidosis of bone of beta-2 microglobulin origin.
A case of hemodialysis-associated amyloidosis in a patient who had been on hemodialysis for 10 years is described. Bone lesions were found in the humeral heads, carpal bones, and femoral heads and necks. ⋯ We reconfirmed that bone lesions associated with long-term hemodialysis are manifestations of amyloidosis of beta-2 microglobulin origin. Hemodialysis-associated amyloidosis should be considered in the treatment of long-term hemodialysis patients.
