Bone densitometry in osteopenia of prematurity Osteopenia of premalury is seen more frequently as more very low birth weight babies survive. Diagnosis based on classical radiological or alcaline phosfafase deletminations is not reliable. Bone densitometry has rarely oeen used at this age. In order lo asses ih value in the diagnosis of osleopenia of prematurity, 12 pteterm babies [gestationaf age 25 to 30 weeks) and 10 control babies (36 and 37 weeks gestational age) wefe studied prospecth/ely. Determinations were done in a double photon 2600 Norlan densitometer. Values were expresed as IBM (total bone mineral), IBM/Weight, and BMD (bone mineral density]. Controls had a mean birth weight of 2 833 g, all were exdusively breast fed and were studied before age 3 days. Mean birth weight of study group was 1 238 g, they were studied at 36 and 44 weeks postconceptional age and they were fed with their own s mother milk or a formula which contains 80 mg% Ca and 40mg%P. Control group babies had IBM 54.9 +9.05 g. IBM/Weight 19.65± 1.98 g, and BMD 0.531 ±0.061 g/cm 2. Newborn babies
Localization of functioning parathyroid adenomas by SPECT/CT. Report of two cases Single photon emission computed tomography and computed tomography (SPECT/CT), integrates a gamma camera and a CT scan and is effective for the location of parathyroid adenomas. We report a 55 years old male and a 80 years old female with primary hyperparathyroidism. In both cases the 99m Tc-Sestamibi parathyroid scintigraphy detected a functioning nodule whose presence was confi rmed with SPECT/CT.
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.
