Use of a dual-wave bolus extended over an 8-h period following a pizza meal provided significantly less postprandial hyperglycemia in the late postprandial period (8-12 h) with no increased risk of hypoglycemia.
BackgroundStreptococcus intermedius is a member of the Streptococcus anginosus group. Clinical disease with S. intermedius is characterized by abscess formation and rarely endocarditis. Identification of Streptococcus intermedius is difficult, leading to the development of molecular methods to more accurately identify and characterize this organism.Case presentationOver a period of 6 months we encountered three cases of invasive Streptococcus intermedius infection presenting as hepatic abscesses, brain abscess, and endocarditis. We confirmed our microbiologic diagnosis through 16S sequencing and found a common virulence gene in each case.ConclusionOur report illustrates three different clinical manifestations due to Streptococcus intermedius infection that can be encountered in healthy individuals in a community hospital setting. To our knowledge, this is the first case of Streptococcus intermedius endocarditis confirmed by 16S sequencing analysis. The use of molecular methods may allow a better understanding of the epidemiology and pathogenesis of this organism.
Objective. To describe an asymptomatic presentation of severe hypocalcemia secondary to vitamin D deficiency in an elderly patient. Methods. We describe the presentation and clinical course of an elderly woman with asymptomatic severe hypocalcemia referred to an endocrinology clinic for hyperparathyroidism. Results. The patient is an 83-year-old Caucasian woman who presented to an endocrinology clinic for evaluation of hyperparathyroidism, with an intact PTH of 462 pg/mL (normal range 14–72 pg/mL). The same lab report included a serum calcium of 5.2 mg/dL (normal range 8–10.5 mg/dL). She displayed no signs or symptoms of hypocalcemia. Given the extreme severity of hypocalcemia and her age, she was hospitalized. Vitamin D deficiency was suspected and was subsequently confirmed with undetectable serum levels. The patient remained asymptomatic throughout her hospital stay. Total and ionized calcium levels at discharge were 7.2 mg/dL and 1.03 mmol/L (normal range 1.1–1.4 mmol/L), respectively. Conclusion. Physicians should exercise prudent management with respect to the vitamin D status of the elderly patient, as certain patients may exhibit severe hypovitaminosis D and hypocalcemia without apparent clinical symptoms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
