The association between osteoporosis and jawbones remains an argument of debate. Both osteoporosis and periodontal diseases are bone resorptive diseases; it has been hypothesized that osteoporosis could be a risk factor for the progression of periodontal disease and vice versa. Hypothetical models linking the two conditions exist: in particular, it is supposed that the osteoporosis-related bone mass density reduction may accelerate alveolar bone resorption caused by periodontitis, resulting in a facilitated periodontal bacteria invasion.

- A study was conducted to determine the safest duration for anticoagulation therapy after a first unprovoked deep vein thrombosis (DVT) by assessing patients for residual vein thrombosis (RVT) after three months of treatment with vitamin K antagonists (VKAs).
- Among 409 patients, 33.2% had no RVT and stopped VKA therapy, while 66.8% with RVT continued treatment for up to 2 years.
- Results showed that the risk of recurring thrombosis was significantly higher in patients with RVT even after extended treatment, suggesting shorter VKA therapy is adequate for those without RVT.
The acute phase of Mediterranean spotted fever (MSF) is characterized by dramatic changes in cytokine production patterns, clearly indicating their role in the immunomodulation of the response against the microorganism, and the differences in cytokine production seem to influence the extent and severity of the disease. In this study, the single nucleotide polymorphisms (SNPs) of tumor necrosis factor alpha (TNF-alpha) -308G/A (rs1800629) and interleukin-10 (IL-10) -1087G/A (rs1800896), -824C/T (rs1800871), and -597C/A (rs1800872) and the gamma interferon (IFN-gamma) T/A SNP at position +874 (rs2430561) were typed in 80 Sicilian patients affected by MSF and in 288 control subjects matched for age, gender, and geographic origin. No significant differences in TNF-alpha -308G/A genotype frequencies were observed.

Clin Gastroenterol Hepatol
January 2009
Background & Aims: Rectal bleeding and lymphonodular hyperplasia (LNH) in children can be caused by food hypersensitivity (FH). Our aim was to verify whether similar clinical and endoscopy presentations in adults can be due to FH.
Methods: Consecutive adult patients with rectal bleeding were enrolled.
The pathogenetic mechanisms, risk factors and relationship between densitometric data and risk of fractures have been examined. The results of treatment trials and prevention measures have been showed.

In the last years the number of Bartonella species significantly raised, often with an epidemiological profile of emergent disease. B. bacilliformis is the etiological agent of Carrion's disease.

We designed the epidemiological project "Ventimiglia di Sicilia" to characterize the risk profile in a rural village with low total cholesterol levels and low early cardiovascular mortality but with a large prevalence of overweight and obesity, which previously have been significantly associated with total mortality.
Methods: 488 individuals of age 20 to 69 years were included in the dietary survey conducted by a seven-day food record.
