Effects of thyroidectomy alone or followed by radioiodine ablation of thyroid remnants on the outcome of graves' ophthalmopathy.

Fifty-five patients with Graves' disease (GD) and mild to moderate Graves' ophthalmopathy (GO) underwent near-total thyroidectomy (Tx). In 16 patients this was followed by a standard ablative dose of (131)I because of the hystologic evidence of differentiated thyroid carcinoma. We retrospectively evaluated whether or not GO activity could be affected by thyroid surgery alone or followed by complete ablation of thyroid tissue. Accordingly, on the basis of clinical activity score (CAS) values prior to thyroidectomy, we identified two groups: group A with active GO (CAS > or = 3; n = 31) and group B with inactive GO (CAS < or = 2; n = 24). CAS values were then recorded at 6, 12, and 24 months after surgery/(131)I ablation. Over the course of the follow-up period, GO became inactive in approximately 70% of group A patients (CAS 4.2 +/- 0.8 at baseline, 2.1 +/- 2.0 at 24 months, p < 0.0001) and became active in 37.5% patients from group B. When we examined GO activity according to the type of treatment used (Tx or Tx and (131)I), the prevalence of inactive GO both short- and long-term, was significantly higher in the group of patients who underwent Tx and (131)I ablation. Therefore, this seems to be a more effective means of inducing and maintaining inactive GO.     

Epidemiology and clinical course of Behçet's disease in the Reggio Emilia area of Northern Italy: A seventeen‐year population‐based study

Objective

To investigate the epidemiology and clinical course of Behçet's disease (BD) over a 17‐year period in a defined area of northern Italy.

Methods

All patients with incident BD diagnosed over a 17‐year period (from January 1, 1988 to December 31, 2004) living in the Reggio Emilia area were identified through the following sources: physicians at Reggio Emilia Hospital, medical practitioners, and community‐based specialists. We identified all patients registered in a centralized index and in the Reggio Emilia district database for rare diseases. Patients were followed up from the time of diagnosis until either their death or April 1, 2005.

Results

Eighteen patients (9 men and 9 women) had complete BD. Mean ± SD age at diagnosis was 33 ± 7 years. The incidence rate of BD was 0.24 per 100,000. The prevalence of BD on January 1, 2005 was 3.8 per 100,000. No patients died during the followup period. Although all patients developed oral ulceration during the disease course, 22.2% had no oral lesions at disease onset. Eye disease occurred in 55.6%. Ocular disease was more common in men and appeared at disease onset or within the first few years of disease onset (median 3 years). Only 1 patient had loss of useful vision in at least 1 eye at the end of followup. In all affected patients, visual acuity improved once treatment was started.

Conclusion

This population‐based study is the first to report the prevalence and incidence of BD in Italy. In Italian patients, BD is nonfatal and the prognosis of eye disease is good.     

Lytic Growth of Human Herpesvirus 8: Morphological Aspects

The human herpesvirus 8 (HHV-8), also known as Kaposi's sarcoma-associated herpesvirus, is a gamma herpesvirus associated with AIDS-related body cavity-based lymphomas (BCBL), also called primary effusion lymphomas (PEL). These are a rare form of non-Hodgkin lymphomas in which HHV-8 is present, often associated with Epstein-Barr virus (EBV) infection. HHV-8 is also present in a latent state or in a state of low-level persistence in different primary effusion lymphoma-derived cell lines, such BCBL-1 cells, that lack EBV infection. This cell line was induced to produce mature virions by treatment with 12- O -tetradecanoyl phorbol-13-acetate (TPA) and the characteristic ultrastructural features of HHV-8 lytic replication were identified and compared to those of the other members of Herpesviridae family.     

Right but not left angular gyrus modulates the metric component of the mental body representation: a tDCS study

The parietal lobes contribute to body-space representation. The present work aims at characterizing the functional role of the inferior parietal lobe in body-space representation and at studying the different roles of the angular gyrus in the right and left hemisphere. We conducted three separate transcranial direct current stimulation (tDCS) experiments using “tactile distance task” as an implicit measure of body representation. Whereas anodal tDCS on the right angular gyrus influences vocal reaction times (vRT) for stimuli delivered on the ipsilateral body parts without changes of accuracy, right tDCS improved both vRT and accuracy for tactile stimuli on the contralateral limbs. Sham or left parietal anodal tDCS had no effect. These evidences support the view that right parietal areas have a crucial role in the metric component of the body representation.     

Is CA72-4 a Useful Biomarker in Differential Diagnosis between Ovarian Endometrioma and Epithelial Ovarian Cancer?

Background. Surgical excision of ovarian endometriomas in patients desiring pregnancy has recently been criticized because of the risk of damage to healthy ovarian tissue and consequent reduction of ovarian reserve. A correct diagnosis in cases not scheduled for surgery is therefore mandatory in order to avoid unexpected ovarian cancer misdiagnosis. Endometriosis is often associated with high levels of CA125. This marker is therefore not useful for discriminating ovarian endometrioma from ovarian malignancy. The aim of this study was to establish if the serum marker CA72-4 could be helpful in the differential diagnosis between ovarian endometriosis and epithelial ovarian cancer. Methods. Serums CA125 and CA72-4 were measured in 72 patients with ovarian endometriomas and 55 patients with ovarian cancer. Results. High CA125 concentrations were observed in patients with ovarian endometriosis and in those with ovarian cancer. A marked difference in CA72-4 values was observed between women with ovarian cancer (71.0%) and patients with endometriosis (13.8%) (P < 0.0001). Conclusions. This study suggests that CA72-4 determination can be useful to confirm the benign nature of ovarian endometriomas in women with high CA125 levels.     

What Happens at a Dental Surgery When the Patient is a Child with Autism Spectrum Disorder? An Italian Study

Oral health care can be a difficult experience for a child with Autism Spectrum Disorder (ASD), for their family and for the dentist. The purpose of this study is to provide an understanding of the challenges experienced by the three aforementioned figures during oral care treatment. A cohort of 275 parents of typical development children (TD), 57 parents of children with ASD (3–15 years old) and by 61 dentists, completed two different multiple choices questionnaires. The data obtained show a great difficulty in the treatment of children with ASD as seen by the dentists and by the parents. This is due to: caregivers’ demographic issues; difficulties encountered before and during the dental examination; scarce presence of experts in ASD treatment.

     

Leukocyte and platelet activation in patients with giant cell arteritis and polymyalgia rheumatica: A clue to thromboembolic risks?

Ischemia is a leading causes of morbidity in giant cell arteritis (GCA). We studied circulating platelets and leukocytes in patients with GCA and with polymyalgia rheumatica. Normal healthy donors (>60 a) served as controls. Patients had a significantly greater fraction of platelets expressing P-selectin, of platelet–Nph and platelet–Mo aggregates, and of Nph and Mo expressing tissue factor. These differences were correlated with the percentage of platelets expressing P-selectin and were not influenced by clinical features or by systemic inflammation. Activated circulating leukocytes and platelets could contribute to indolent vessel inflammation and possibly to thromboembolic events in patients with systemic large vessel vasculitis.
