ABSTRACT

PURPOSE: Vertebral fractures are associated with persistent pain, disability and mortality. However, around two thirds of women with vertebral fractures are unaware of them. We aimed to analyze which factors could mostly be associated to the presence of vertebral fractures in post-menopausal women, and evaluate the effectiveness of current screening criteria for the detection of vertebral fractures in an outpatient setting. METHODS: We evaluated 1132 post-menopausal women referred to the osteoporosis outpatient clinic of the Geriatrics Department of Padova. For each participant we assessed: anthropometric data, femoral and lumbar bone mineral density (BMD), dorso-lumbar X-rays, bone metabolism markers. Current recommendations for X-ray examinations by SIOMMMS (Società Italiana di Osteoporosi, Metabolismo Minerale e Malattie dello Scheletro) and ISCD (International Society of Clinical Densitometry) versus routine X-ray examinations were considered, and fracture risk was assessed through the derived FRAX (DeFRA) tool. RESULTS: Of the women included in our study, 28% presented vertebral fractures, most of these previously unknown (82.8%). Lumbar BMD did not differ between patients with and without vertebral fractures. According to SIOMMMS guidelines, 50% of patients <60 years with unknown vertebral fractures would have been excluded from spinal X-ray examination. According to ISCD recommendations, the number of patients excluded reached 94.6% in the <60 age-group and 84.9% in the 60-70 age-group. The under-identification of vertebral fractures led to the 10-year risk of fractures computed by DeFRA being underestimated by around 15%. CONCLUSIONS: BMD, particularly in the lumbar site, may not properly predict the presence of vertebral fractures in post-menopausal women. Improvement of the current recommendations for spinal X-ray examination may lead to early identification and better management of patients with vertebral fractures.

ABSTRACT

A long history of diabetes mellitus and increasing age are associated with the onset of diabetic neuropathy, a painful and highly disabling complication with a prevalence peaking at 50% among elderly diabetic patients. Acetyl-L-carnitine (ALC) is a molecule derived from the acetylation of carnitine in the mitochondria that has an essential role in energy production. It has recently been proposed as a therapy to improve the symptoms of diabetic neuropathy. ALC is widely distributed in mammalian tissues, including the brain, blood-brain barrier, brain neurons, and astrocytes. Aside from its metabolic activity, ALC has demonstrated cytoprotective, antioxidant, and antiapoptotic effects in the nervous system. It exerts an analgesic action by reducing the concentration of glutamate in the synapses. It facilitates nerve regeneration and damage repair after primary trauma: its positive effects on metabolism promote the synthesis, fluidity, and functionality of neuronal membranes, increase protein synthesis, and improve the axonal transport of neurofilament proteins and tubulin. It also amplifies nerve growth factor responsiveness, an effect that is believed to enhance overall neurite growth. ALC has been proposed for the treatment of various neurological and psychiatric diseases, such as mood disorders and depression, dementias, Alzheimer's disease, and Parkinson's disease, because synaptic energy states and mitochondrial dysfunction are core factors in their pathogenesis.

ABSTRACT

HCMV infection is a major cause of morbidity and mortality following kidney transplantation. Clinical diagnosis is difficult, and rapid and sensitive diagnostic methods are needed since antiviral therapy is available. One hundred-forty-five consecutive kidney-transplanted patients were studied during a period of three months after transplantation. For laboratory diagnosis of HCMV infection, we looked for the presence of pp-65 antigen in polymorphonuclear leukocytes, HCMV-DNA and IgM. Demonstration of HCMV pp-65 antigen by immunofluorescence and HCMV DNA by PCR in leukocytes were efficient methods for early diagnosis of infection.
