Matrix metalloproteinase-9 (MMP-9) was detected by zymography and enzyme-linked immunosorbent assay (ELISA) in matched serum and cerebrospinal fluid (CSF) samples from patients with neurological diseases. Patients with relapsing-remitting multiple sclerosis (RR-MS) had serum and CSF MMP-9 levels comparable to those from patients with inflammatory neurological diseases (INDs), but higher than patients with non-inflammatory neurological diseases (NINDs) and healthy donors (HDs). MMP-9 increased in active RR-MS in comparison with inactive RR-MS implying that MMP-9 in MS is related with clinical disease activity. A correlation between the CSF/serum albumin (Q(AIb)) and CSF/serum MMP-9 (Q(MMP-9)) was observed in IND and NIND but not in RR-MS patients, indicating that CSF MMP-9 levels in NIND and IND patents could be influenced by serum MMP-9 and blood-brain barrier (BBB) permeability properties. MS patients had higher values of Q(MMP-9):Q(Alb)(MMP-9 index) than IND and NIND patients suggesting that in MS the increase in CSF MMP-9 could be due to intrathecal synthesis of MMP-9. A significant inverse correlation was found between MMP-9 and its endogenous inhibitor TIMP-1 in RR-MS indicating that in MS patients both the increase in MMP-9 and the decrease in TIMP-1 serum levels could contribute to BBB disruption and T-lymphocyte entry into the CNS.

Scleroderma is a disorder involving oral and facial tissues, with skin hardening, thin lips, deep wrinkles, xerostomia, tongue rigidity, and microstomia. The aim of this study was to investigate the prevalence of oral manifestations and temporomandibular disorders (TMD) in Systemic Sclerosis (SSc) patients compared with healthy people. Eighty patients (6 men, 74 women) fulfilling ACR/EULAR SSc Criteria were enrolled. A randomly selected group of 80 patients, matched by sex and age served as control group. The examination for TMD signs and symptoms was based on the standardized Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) through a questionnaire and clinical examination. SSc patients complained more frequently (78.8%) of oral symptoms (Xerostomia, dysgeusia, dysphagia and stomatodynia) than controls (28.7%) (χ2 = 40.23 p = 0.001). TMD symptoms (muscle pain on chewing, difficulty in mouth opening, headaches) were complained by 92.5% of SSc patients and by 76.2% of controls (χ2 = 8.012 p = 0.005). At the clinical examination, 85% of SSc patients showed restricted opening versus 20.0% of controls (χ2 = 67.77 p = 0.001), 81.2% of SSc showed reduced right lateral excursion versus 50% of controls (χ2 = 17.316 p = 0.001); 73.8% of SSc showed limited left lateral excursion versus 53.8% of controls (χ2 = 6.924 p = 0.009); and 73.8% of SSc had narrow protrusion versus 56.2% of controls (χ2 = 5.385 p = 0.02).

We provide evidence that serum sarcosine has a higher predictive value than tPSA and %fPSA in patients with PSA < 4 ng/ml. Moreover, sarcosine levels were significantly different in low grade versus high grade cancers in this subset of patients, suggesting that this marker may be a further tool not only for diagnosing PCa in normal PSA and abnormal DRE/TRUS patients but also for selecting candidates for non-aggressive therapies and active surveillance.

A randomised placebo controlled study was performed in 32 women with intrdhepatic cholestasis of pregnancy. The population was divided into four groups: for 20 days each group was treated only with ursodeoxycholic acid, or S-adenosylmethionine, or a combination of both drugs, or a placebo (vitamin). Itching, standard liver function tests and serum total bile acids were measured before, during, and after treatment. Itching improved in all the women as well as the biochemical abnormalities. No side-effects in the mother or in the infant were recorded during and after therapy. A combination of ursodeoxycholic acid and S-adenosylmethionine is more effective than placebo and than either drug alone.
