Effects of Three Interventions Combining Impact or Walking at Intense Pace Training, with or without Calcium and Vitamin Supplements, to Manage Postm…
2022
The purpose was to assess the effects of three interventions on bone mineral density (BMD) to prevent the onset or progression of osteoporosis in postmenopausal women. Specifically, thirty-nine postmenopausal women, diagnosed with osteopenia or osteoporosis, implemented either high-impact training (G1), the same training + calcium and vitamin D intake (G2), or walked at an intense pace + calcium and vitamin D (G3). Baseline change (BC) in BMD was estimated using the femoral neck and lumbar spine T-scores. Participants were classified as having suffered fractures and/or falls before (24-month) and during the 2-year intervention. The participants—aged 61.8 years—were allocated int…
The Exosomes-derived EGFR Ligand Amphiregulin (AREG) is a new key player in Multiple Myeloma Bone Destruction
Il Mieloma Multiplo (MM) è caratterizzato dalla presenza di aree osteolitiche dovute alla presenza di plasmacellule (PC) neoplastiche che causano l'interruzione della normale omeostasi ossea, promuovendo l'attività degli osteoclasti (OC) ed inibendo la funzione degli (OB). Al momento, uno dei campi di ricerca nella fisiopatologia del MM è proprio lo studio dei meccanismi che regolano l’attività degli OC e degli OB così come l’identificazione di target terapeutici per la prevenzione ed il trattamento delle lesioni osteolitiche. Negli ultimi anni è emerso che le vescicole extracellulari (EV), ed in particolare gli esosomi, giocano un ruolo fondamentale nel mediare il cross-talk tra le cellule…
Tuberkulöse Destruktion des Iliosakralgelenkes
2001
In dieser Kasuistik wird der Fall einer tuberkulosen Destruktion des rechten Sakroliakalgelenks eines 56-jahrigen Patienten vorgestellt. Auffallig sind die verspatete Diagnose durch Verwechslung der Beschwerdesymptomatik mit einer Lumbalgie durch Bandscheibenprolaps und die Abszedierung entlang der Psoasmuskulatur und in die umgebende intra- und extrapelvine Muskulatur. Die Therapie ist eine chirurgische, die durch eine einjahrige medikamentose Kombinationstherapie erganzt wird.
Peculiar hyper-IgM syndrome. Case report / Sindrom hiper-IgM atipic. Prezentare de caz
2015
Abstract We report a male infant diagnosed at the age of 10 months with hyper-IgM syndrome (HIGM) in context of severe infections caused by Streptococcus pneumoniae, Staphylococcus aureus and Candida albicans. In patient’s outcome, in spite of immunoglobulin therapy, he continues presenting bilateral suppurative otitis media due to both Candida and penicillin-resistant pneumococcus and forearm abscess caused by Staphylococcus aureus. The infant developed bilateral cataracts, chronic hepatitis and comminuted fracture secondary to bone demineralization. The patient didn’t develop opportunistic infections as compare to CD40 Ligand deficiency patients. In contrast with the majority of HIGM case…
Bedeutung der Ganzkörper-Skelettszintigraphie im Rahmen des Staging von Malignomen im HNO-Bereich*
1992
Concerning malignant tumours of the oral cavity, pharynx and larynx, bone metastases are in general rarely seen. For the specification to which patients the whole body bone scintigraphy as detection method should be applied, the findings of 370 patients were analysed retrospectively. In respect of primary staging, bone metastases could be found by scintigraphy in only 1.4% of the patients. On the other hand, there was a detection rate of 12% during the further course of the disease, especially in case of clinical symptoms pointing at spreading metastases or in tumour recurrences. Nevertheless, positive scan findings which were not due to metastases could be found in both groups with equal f…
Bone metastases in soft tissue sarcoma: a survey of natural history, prognostic value and treatment options
2013
Abstract Background We surveyed the natural history of bone metastases in patients affected by soft tissue sarcoma (STS). Methods This multicenter retrospective observational study included 135 patients. Histological subtype, characteristics of bone metastases, treatment, skeletal related events (SREs) and disease outcome were recorded. Results The most represented histological subtypes were leiomyosarcoma (27%) angiosarcoma (13%) and undifferentiated sarcoma (8%). Axial skeleton was the most common site for bone involvement (70%). In 27% of cases, bone metastases were present at the time of diagnosis. Fifty-four (40%) patients developed SREs and the median time to first SRE was 4 months (r…
Adverse drug reactions to antiretroviral medication
2009
Antiretroviral therapy has greatly improved prognosis of HIV infection, with a dramatic reduction of morbidity and mortality worldwide. Nevertheless, the condition is still a common cause of death in many underdeveloped countries, where effective treatment is not always unavailable. More than 20 drugs active against HIV are commercially available, which belong to one of four groups: nucleoside reverse transcriptase inhibitors, non-nucleoside reverse transcriptase inhibitors, protease inhibitors, and fusion/entry inhibitors. In the near future new drugs are expected, including those of a novel group, the integrase inhibitors. To avoid viral resistance, combinations of the drugs must always b…
Significant liver fibrosis assessed using liver transient elastography is independently associated with low bone mineral density in patients with non…
2017
Background Metabolic bone disorders frequently occur in patients with chronic liver disease; however, the association between liver fibrosis and bone mineral density in patients with non-alcoholic fatty liver disease (NAFLD) is unclear. Methods This is a cross-sectional analysis of 231 asymptomatic subjects (160 women, 61.6 years old) from a university hospital setting, between February 2012 and December 2014. Bone mineral density (BMD) was measured at the lumbar spine, femur neck, and total hip using dual-energy X-ray absorptiometry (DXA). Liver fibrosis and steatosis were assessed using transient elastography. Results Among a total of 231 individuals, 129 subjects (55.8%) had NAFLD. BMDs …
Platelet-Rich Plasma (PRP) in Dental Extraction of Patients at Risk of Bisphosphonate-Related Osteonecrosis of the Jaws: A Two-Year Longitudinal Study
2020
: Dental extraction has often been described as the main trigger event of osteonecrosis of the jaws (ONJ). This longitudinal hospital-based study aimed to evaluate the outcome at 2 years of a standardized medical-surgical protocol for dental extraction, combined with platelet rich-plasma (PRP) application, compared with conventional protocol not combined with PRP or any other autologous platelet concentrate in cancer (ONC) and osteometabolic (OST) patients, at risk of bisphosphonate (BP)-related ONJ. Twenty patients were consecutively recruited: six received BPs for cancer skeletal-related events (34.17 ±
De Novo Mutations in SLC25A24 Cause a Disorder Characterized by Early Aging, Bone Dysplasia, Characteristic Face, and Early Demise
2017
International audience; A series of simplex cases have been reported under various diagnoses sharing early aging, especially evident in congenitally decreased subcutaneous fat tissue and sparse hair, bone dysplasia of the skull and fingers, a distinctive facial gestalt, and prenatal and postnatal growth retardation. For historical reasons, we suggest naming the entity Fontaine syndrome. Exome sequencing of four unrelated affected individuals showed that all carried the de novo missense variant c.649C>T (p.Arg217Cys) or c.650G>A (p.Arg217His) in SLC25A24, a solute carrier 25 family member coding for calcium-binding mitochondrial carrier protein (SCaMC-1, also known as SLC25A24). SLC25A24 all…
