Evaluation of Heavy Metals and Polycyclic Aromatic Hydrocarbons (PAHs) in <Emphasis Type="Italic">Mullus barbatus</Emphasis> from Sicily Channel and Risk-Based Consumption Limits

Our study is a preliminary step to evaluate water contamination of the Mediterranean Sea surrounding Lampedusa island and health risks for fish consumers. We analyzed muscle tissue of Mullus barbatus specimens to detect metals and polycyclic aromatic hydrocarbons (PAHs). Results show the following average concentrations of heavy metals: Pb 0.035, Cd 0.001, Hg 0.027, Cr 0.524, As 27.01, Cu 0.433, Co 0.013, Ni 0.042, Se 0.487, V 0.072, U 0.055 and Zn 3.360 ppm. PAHs ranged from 0.250 to 13.16 ppb. A possible risk to human health was determined based on consumption limits data and the content of total PAHs in fillets of this species.     

Oocyte cryopreservation: oocyte assessment and strategies for improving survival

Despite significant progress in cryopreservation of mammalian oocytes and embryos, many ofthe molecular and biochemical events that underlie this technology are poorly understood. In recent years, researchers have focused on obtaining viable oocytes that are developmentally competent. Even under the most favourable conditions, experimental approaches have achieved only limited success compared with fresh oocytes used in routine in vitro embryo production. Chilling injuries and toxic effects of the cryoprotectants are the major adverse consequences following cryoprocedures. To overcome these problems, different strategies have been developed for improving cryopreservation results. These strategies include reducing container volumes, increasing the thermal gradient, changing the cell surface/volume ratio, enhancing cryotolerance by supplementation with various additives or modifying the lipid composition of the oocyte membrane. In order to develop new strategies for reducing the various forms of stress associated with oocyte cryopreservation, it is fundamental to gain a better understanding of the major changes responsible for poor post-thaw survival. With this knowledge, we hope that oocyte cryostorage will become a fully reliable reproductive technique in the near future.     

Combined oral lysine acetylsalicylate and metoclopramide in the acute treatment of migraine: a multicentre double-blind placebo-controlled study

This multicentre, double-blind, randomized, placebo-controlled, parallel study was designed to evaluate the efficacy of combined oral lysine acetylsalicylate and metoclopramide (LAS-MCP) in the acute treatment of migraine attacks. A total of 266 patients, 18–65 years old, with two to six attacks of migraine with or without aura (IHS criteria) per month were included. The patients had to treat two migraine attacks with LAS-MCP (1620 mg lysine acetylsalicylate-the equivalent of 900 mg aspirin- combined with 10 mg metoclopramide) or placebo. The main outcome measure was headache relief (reduction in headache severity from grade 3 or 2-severe or moderate-to grade 1 or 0-mild or none) 2 h after treatment. LAS-MCP was superior to placebo for headache relief (56% vs 28%) and for the following secondary outcome measures: complete headache relief (18% vs 7%; p < 0.001), nausea (28% vs 44%; p < 0.001), vomiting (3% vs 11%; p = 0.001), use of rescue medication (47% vs 68%; p < 0.001), global efficacy judged as good or excellent (32% vs 14%; p < 0.001). The tolerability was considered as good in 94% of treated attacks in both groups. Combined oral lysine acetylsalicylate and metoclopramide is an effective and well-tolerated acute treatment of migraine attacks.     

Characterization of circulating and monocyte-derived dendritic cells in obese and diabetic patients

Dendritic cells (DCs) are suspected to be involved in the development of atherogenesis, but their role is still unclear. The aim of this study was to characterize circulating DCs and monocyte-derived DCs (Mo-DCs) of obese and diabetic patients (T2D), and to study their interaction with human coronary smooth muscle cells (CASMCs). Obese post-menopausal women with or without insulin resistance were enrolled and were compared to age-matched healthy women. Myeloid circulating DCs significantly increased in obese T2D patients compared to healthy donors and a smaller increase was observed for plasmacytoid one. Mature Mo-DCs from obese T2D patients significantly decreased when compared to control, but they were significantly more capable of adhering to CASMCs compared to that from healthy controls and from not-T2D obese subjects. Altogether these data suggest that in conditions of insulin-resistance and obesity there is an up-regulation of myeloid DCs that might contribute to pathological vascular remodeling.     

Early-onset Psychoses: Comparison of Clinical Features and Adult Outcome in 3 Diagnostic Groups

A comparison of clinical features and adult outcome in adolescents with three types of psychotic disorders: schizophrenic (SPh), schizoaffective (SA) and bipolar with psychotic features (BPP). Subjects (n = 41) were finally diagnosed (DSM-IV criteria) with SPh (n = 17), SA (n = 11) or BPP (n = 13). Clinical evaluation took place at onset and at a 3-year follow-up in all 41, and at least after 5 years in 36 patients. Symptoms were rated on the basis of the Positive and Negative Syndrome Scale (PANSS), integrating items from the Brief Psychiatric Rating Scale (BPRS) and the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL). The Children Global Assessment Scale (C-GAS) and the Global Assessment Scale (GAF) were used to evaluate global functioning. Significant differences in clinical features were found in the three diagnostic groups as regards several parameters, some present on one and not on other rating scales, underscoring the insufficiency of a single scale for accurate analysis of the features of a psychotic disorder. At onset, a comparison using the simple presence/absence of symptoms showed scant differences among groups, while differences emerged if symptom severity was included in the comparison. Functioning at 3- and 5-year follow-ups showed a significantly better outcome in the BPP group and more substantial deterioration, with similar evolution, in the SPh and SA groups. The integration of several rating scales differentiated between diagnostic groups more effectively. The similar adult functioning outcome in the SPh and SA groups showed how difficult it is to clearly separate these two disorders.     

A mathematical model for the evaluation of amplitude of hemoglobin fluctuations in elderly anemic patients affected by myelodysplastic syndromes: correlation with quality of life and fatigue

Therapy with RBC transfusions and rHuEPO for management of anemia in patients with myelodysplastic syndromes causes recurrent fluctuations in hemoglobin levels. The purpose of this study was to elaborate a mathematical model for the interpretation of hemoglobin fluctuations and to correlate the resulting numerical parameter (Variaglobin Index) with quality of life and fatigue. In 32 myelodysplastic patients, lower amplitude of the Variaglobin Index was found significantly correlated with a better quality of life and less fatigue. The mathematical model proposed here makes it easy to monitor anemia in myelodysplastic patients and to adjust therapy accordingly.     

The east–west advancement flap (horizontal advancement flap) to repair a defect on the nose ala

Background The repair of an alar nasal defect is a frequent challenge for dermatologic surgeons for reasons of the high rate of non‐melanoma cancers in the area. Objective Our aim was to describe the use of an east–west cheek‐based flap (horizontal advancement flap) to repair a surgical defect on the nose ala. Methods Benefits and limits of this surgical procedure are evaluated. Result The resulting S‐shaped scar was well‐camouflaged among the natural skin lines (melolabial fold and melonasal junction). No architectural distortion of the nose resulted from the procedure. Conclusion In selected patients with small‐to‐medium‐size defects of the nasal ala, the horizontal advancement flap is a simple, reliable and aesthetic reconstruction option.
