Care of diabetic patients in hospital clinics and general practice clinics: a study in Dudley.

A five year retrospective casenote review was undertaken of 452 patients attending 11 different general practice diabetic clinics, and 506 patients attending a diabetic clinic at hospital A and 210 patients attending a diabetic clinic at hospital B. The populations attending the clinics, the degree of glycaemic control achieved and the monitoring for the development of diabetic complications were investigated. Insulin dependent patients comprised 57.9% of patients attending the diabetic clinic at hospital A, 35.7% at hospital B and 25.0% of patients attending the diabetic clinics at general practices. Of these 55.6%, 37.3% and 30.1% respectively received multiple daily insulin injections. Hospital A had a higher proportion of patients under 40 years old than hospital B or the general practice clinics. The ages of diabetic patients attending the general practice diabetic clinics were broadly similar to those attending hospital B. Significantly more general practice patients, both insulin and non-insulin dependent, had a mean blood glucose level of less than 11 mmol l-1 compared with patients attending clinics at hospitals A and B (P < 0.001). Glycosylated haemoglobin levels did not differ between patients attending hospital A and the general practice clinics. More non-insulin dependent and insulin dependent diabetic patients attending the general practice clinics and hospital A had been monitored satisfactorily for diabetic retinopathy (general practice clinic 68.8% and 39.7% respectively, hospital A 61.7% and 43.5%) than at hospital B (43.0% and 19.4%). Referral rates among all groups for ophthalmological assessment were similar.(ABSTRACT TRUNCATED AT 250 WORDS)

Familial nephropathic non-neuropathic amyloidosis: clinical features, immunohistochemistry and chemistry.

Classification of familial amyloidosis by the chemical nature of the fibrillar protein has become possible. Most such amyloidogenic proteins so far recognized are variant transthyretins, but two kindreds with the same apolipoprotein AI modification have been reported. We describe the clinical features of another such family in whom petechial skin rash appeared to be a marker for the disease, which was non-neuropathic and of the Ostertag-type. Immunohistochemistry showed the protein to be apolipoprotein AI, but allele-specific DNA amplification indicated that it was not the Arg26 variant previously identified.

Disappearing hypercalcaemia.

Four women presented with symptomatic hypercalcaemia and raised concentrations of serum parathyroid hormone (PTH). In each case, serum calcium returned spontaneously to normal. In two patients serum PTH also fell to the normal range and biochemical relapse has not occurred despite prolonged follow-up. In the others, serum PTH remained elevated and subsequent symptomatic hypercalcaemia necessitated parathyroidectomy. In the first two cases, autoparathyroidectomy is the most likely explanation; the initial fall in serum calcium in the other two patients is unexplained. Large fluctuations in serum calcium may occur in some patients with hyperparathyroidism and prolonged and careful observation is required when this occurs.

Elevation of free thyroxine measurements in patients without thyrotoxicosis.

The recent development of single step analogue assay techniques to measure free thyroxine in serum has meant that this estimation has become widely used as a first line test of thyroid function. However these assays are subject to in-vitro interference in two ways: where there is a variant serum albumin in familial dysalbuminaemic hyperthyroxinaemia, or where there are circulating thyroid hormone binding antibodies. In both these situations a spuriously high result for free thyroxine is obtained. This may have serious implications for patient management and we describe 10 patients in whom the finding of a misleadingly high free thyroxine concentration led to confusion in diagnosis and, in eight of the 10, to inappropriate antithyroid treatment. Clinicians should be aware of these technical problems and where a result for the free thyroxine concentration seems inappropriate to the patient's clinical state then measurement of thyrotrophin (TSH) by a sensitive immunometric method should be performed. If the results remain confusing the presence of a variant serum albumin or thyroid hormone binding antibodies should be sought.

Anorexia nervosa presenting as reversible hypoglycaemic coma.

Hypoglycaemic coma was the presenting feature in two patients with anorexia nervosa, both of whom rapidly regained consciousness following intravenous administration of glucose. This uncommon complication of malnutrition does not appear to have been reported previously in anorexia nervosa.
