A community survey of ptosis of the eyelid and pupil size of elderly people.

A randomly selected, age-stratified sample of subjects 50 years of age and older, living in the Salford Health District area of Greater Manchester was drawn from the age-sex register of a four-doctor group practice and invited by post to enter a study of ptosis. Of 851 subjects approached, 499 (59%) replied. Of these, 99 refused to participate. The remaining 400 were visited at home and underwent a standardized protocol of ophthalmic history, and examination including a photograph of the eyes in the primary position. Forty-six (11.5%) of the subjects had ptosis and its prevalence increased with age. Ptosis was bilateral in 18 (39%) and unilateral in 28 (61%). In all but four cases, the ptosis was acquired. The cause was evident in 23 (50%), with 11 cases being due to mechanical ptosis and 12 to aponeurotic disinsertion secondary to a known pathology. A further 22 cases had primary aponeurotic disinsertion and there was one case of probable myasthenia gravis. The prevalence of pupillary diameter of 1 mm or less increased significantly with age.

Gallstone cirrhosis: are we only seeing the tip of the iceberg?

Gallstones are common and their incidence increases with age. Fifty per cent of these stones are in the common bile duct (CBD) in the elderly. Most of them are silent but with time there is an increasing chance of developing symptoms which are more likely to be serious in the elderly. Failure to relieve mechanical obstruction of bile flow may lead to secondary biliary cirrhosis. It has been estimated that on average secondary biliary cirrhosis develops some seven years after the onset of obstruction from a stricture, four and half years after gallstone obstruction and 10 months after the onset of malignant stricture. The characteristic features are the pathological findings of portal-portal linkages, with a pattern of monolobular cirrhosis and the preservation of normal vascular relationships. Secondary biliary cirrhosis may lead to hepatic insufficiency and portal hypertension with the resultant complications, such as bleeding oesophageal varices, hypersplenism with pancytopenia, ascites and encephalopathy. We describe a patient in whom the diagnosis was not suspected until laparotomy and confirmed only at autopsy.

Guillain-Barré syndrome in the elderly. A retrospective comparative study.

There have been no reported studies specifically devoted to the Guillain-Barré syndrome in elderly patients. The survey reported in this paper investigated the manifestations of the disease in older patients and compared them with those seen in younger patients. All adult patients with an established diagnosis of Guillain-Barré syndrome admitted over 9 years to a Regional Referral Centre providing services for a population of 543,213 were identified and studied. Fifteen patients were over the age of 60 years and 21 between 19 and 60 years of age. Antecedent illnesses and, in particular, gastro-intestinal symptoms were reported less frequently in older patients. Where there was an antecedent illness, this was of shorter duration in elderly subjects. Neurological symptoms related to peripheral nerve damage, such as paraesthesiae, myalgia, backache and an inability to stand, occurred with a similar frequency in both age groups. Double vision and facial weakness, however, occurred less often in older patients, and cerebellar features were not encountered in the older age group. The cerebrospinal fluid immunoglobulin abnormality was more marked in the elderly. The interval between onset and peak severity was shorter in elderly patients. The duration of hospital stay was significantly greater in the elderly, though the overall prognosis was similar in both age groups. There was only one death in each group. The incidence of the Guillain-Barré syndrome in the elderly was higher than in subjects aged 19-60 years, but this difference was not significant.(ABSTRACT TRUNCATED AT 250 WORDS)

"Liver cancer ... or is it?".

There has been a gradual change in the pattern of presentation of pyogenic liver abscess with an increasing incidence in the elderly. At the same time an improvement in mortality with early diagnosis and treatment has been recognised. We describe two patients in whom the diagnosis of liver abscess was not suspected until autopsy in one and aspiration of pus during biopsy of a liver "tumour" in the other.

Pyogenic liver abscess in the elderly.

Seventeen patients over the age of 60 years, admitted to the Aberdeen Teaching Hospitals between 1980 and mid-1988, were diagnosed as having pyogenic liver abscess. Eleven were women and the mean age was 73.5 years. The diagnosis of liver abscess was made by needle aspiration in seven patients and was an unexpected finding at laparotomy in three. Six patients were thought to be suffering from advanced malignant disease until autopsy. The overall fatality was 53%. Misleading results from special investigations reduced the chance of a correct diagnosis in several patients. Even in frail elderly patients, a filling defect in the liver should not be attributed to metastatic malignancy when there is no known primary site, until liver abscess has been excluded by aspiration biopsy under ultrasound or computerized tomographic scan guidance. The high fatality of pyogenic liver abscess seems to be at least in part due to a lack of clinical suspicion.
