Aim: To characterize the frequency of hyperglycemia in a tertiary hospital and to correlate it with length of hospital stay (LOS). Material and Methods: Review of medical records of hospitalized patients. Demographic data and laboratory data, previous diabetes mellitus (DM) history, current main diagnosis, unit of hospitalization and the two highest capillary blood glucose values from the analyzed period were recorded for each patient. LOS was obtained from electronic clinical records. Results: 210 subjects, aged 60 ± 19 years (104 women) were included. 113 patients (54%) developed hyperglycemia ≥ 140 mg/L. Thirty one percent of these had a previous history of diabetes and 29% had stress hyperglycemia (SHG). Patients with a history of DM had a higher average blood glucose than those with SHG (238.9 and 178.2 mg/dL, respectively, p < 0.01) and a greater percentage of cases with a blood glucose above 180 mg/dL (72 and 40.0%, respectively, p < 0.01). Hospital LOS was significantly longer in patients with hyperglycemia ≥ 140 mg/dL as compared with those with normoglycemia (29.3 and 12.8 days, respectively, p < 0.01). This association remained significant when introduced in a linear regression analysis including diagnosis, decreased glomerular filtration rate (GFR) and hospitalization unit (p < 0.01). Conclusions: Hyperglycemia during hospitalization affects more than half of hospitalized patients and is associated with a longer length of stay.

    Polyostotic fibrous dysplasia (McCune-Albright) with rare multiple epiphyseal lesions in association with aneurysmal bone cyst and pathologic fracture
    (Academic Press, 2021) Burdiles A.; Marín R.; Klaber I.; Solar A.; Calderón M.; Jara F.; Kara F.; Bazáes D.
    © 2021Fibrous dysplasia, including McCune-Albright syndrome, is a genetic, non-inheritable benign bone disorder that may involve a single or multiple bone, typically occurring in the diaphysis or the metaphysis of long bones. In very rare instances polyostotic fibrous dysplasia present involvement of the epiphysis in long bones. Aneurysmal bone cysts are benign, expansile, lytic bone lesions formed by cystic cavities containing blood, that may occur de novo or secondary to other lesions of bone, including fibrous dysplasia. We report a case of an 18-year-old female with polyostotic fibrous dysplasia (McCune-Albright syndrome) with diaphyseal and unusual multiple foci of epiphyseal involvement of long bones as well as in the patella, and a simultaneous aneurysmal bone cyst of the left femoral neck with pathologic fracture. This is the first report of a simultaneous aneurysmal bone cyst in a patient with polyostotic fibrous dysplasia (McCune-Albright syndrome) with involvement of diaphysis and epiphysis of long bones, highlighting that fibrous dysplasia should be included in the differential diagnosis of polyostotic tumors involving the diaphysis as well as the epiphysis. In patients with polyostotic fibrous dysplasia there should be an active search for lesions in the epiphysis.
