ABSTRACT
BACKGROUND AND AIMS: To assess the incidence and prognostic value of hypoglycemia in hospitalized non-diabetic elderly patients. METHODS: An observational retrospective study, with a 3-year follow-up, was performed in a series of 678 patients aged over 65 years, admitted between January 1 2001 and December 31 2001 to the Units of Gerontology and Geriatrics of the Careggi University Hospital, Florence, Italy. Patients with diabetes mellitus were excluded. To determine the cumulative incidence of hypoglycemia, all measurements of venous or capillary blood glucose during hospital stay were taken into account. In-hospital mortality was determined from hospital discharge records. Information on all-cause, three-year mortality after hospital admission was obtained from the City of Florence Registry Office. RESULTS: Hypoglycemia was observed in 8.6% of patients, and was asymptomatic in about 25% of cases. In-hospital mortality was significantly higher in patients with hypoglycemia (41.4% vs 14.3%; p<0.001), even after adjustment for potential confounders, including comorbidity, indices of malnutrition, and pharmacological treatment (adjusted OR 2.17[1.25;3.85]). 3-year mortality was significantly higher in patients with hypoglycemia during hospital stay, but the difference was not significant after adjustment for confounders. CONCLUSIONS: Hypoglycemia is a prognostic marker of in-hospital mortality in non-diabetic hospitalized patients, even after adjustment for comorbidity and indices of malnutrition. Instead, it does not seem to have any relevant independent prognostic value in the longer term.

Anderson-Fabry's disease (AFD) is a rare inborn X-linked sphingolipid storage disorder. Deficient activity of the lysosomal enzyme alpha-galactosidase A (alpha-GAL-A) leads to progressive accumulation of glycosphingolipids within most visceral tissues and body fluids of affected patients, provoking a clinical syndrome that includes nervous system, renal, cardiac, ophthalmologic and cutaneous manifestations. Also heterozygous women, who had been considered as healthy carriers until recently, often demonstrate clinical signs of multi-organ involvement. In older women these manifestations are frequently attributed to other more common conditions of older age, and a genetic disorder is rarely hypothesized. We report the cases of two elderly women, who had been diagnosed with AFD at the ages of 70 and 74. Although it is a rare disease, AFD should be considered as a diagnostic hypothesis in women with a clinical history of cardiomyopathy and vascular encephalopathy, appearing at ages 40-50 without identification of major vascular risk factors.

Accumulation of calcium in the skin is usually classified as a group of disorders referred to as calcinosis cutis. We report the case of a patient who developed iatrogenic calcinosis at the site of subcutaneous administration of low-molecular-weight heparins (LMWH) as nadroparin. This is usually used for the prevention of deep venous thrombosis, especially following renal transplantation. The role of calcium content in nadroparin is discussed.
