Screening for impulse control disorders in Parkinson's disease and dopamine agonist use: a study of pharmacokinetic and psychological risk factors.

Introduction: Dopamine agonist (DA) use is considered the main risk factor for impulse control disorder (ICD) development in Parkinson's disease (PD). Besides DAs, personality traits and cognitive features may represent risk factors for ICDs. The primary aim of this study was to investigate differences in DA plasma concentrations in PD patients with and without a positive screening for ICDs according to validated tools.

Reconstruction of the Maxillary Sinus After Previous Major Sinus Elevation Failure: A Study with a 3-Year Follow-up.

Fourteen maxillary sinuses were reconstructed in 12 patients who presented with a previous sinus elevation failure. In all cases, large perforations of the sinus membrane occurred during removal of the failed graft from the sinus; the perforations were sealed with fibrin glue, then the site was grafted using homologous fibrin glue (HFG) mixed with a calcium phosphate scaffold (CPS). Histologic analyses revealed that the CPS-HFG graft was followed by an ossification process, with the formation of spongy bone similar to that of the normal skeleton.

Metabolite Changes After Metabolic Surgery - Associations to Parameters Reflecting Glucose Homeostasis and Lipid Levels.

Aims: To test the hypothesis that adipose tissue gene expression patterns would be affected by metabolic surgery and we aimed to identify genes and metabolic pathways as well as metabolites correlating with metabolic changes following metabolic surgery.

Materials And Methods: This observational study was conducted at the Obesity Unit at the Catholic University Hospital of the Sacred Heart in Rome, Italy. Fifteen patients, of which six patients underwent Roux-en-Y gastric bypass and nine patients underwent biliopancreatic diversion, were included.

Mixed neuropathology in frontotemporal lobar degeneration.

: Frontotemporal lobar degeneration (FTLD) is a significant cause of dementia in mid-life and older adults. The extent of interactions between FTLD and other neurodegenerative pathologies is unclear. We reviewed the occurrences of mixed pathology in cases of neuropathologically diagnosed FTLD from the UK Brain Bank Network.

Biliopancreatic Diversion Induces Greater Metabolic Improvement Than Roux-en-Y Gastric Bypass.

Diabetes remission is greater after biliopancreatic diversion (BPD) than Roux-en-Y gastric bypass (RYGB) surgery. We used a mixed-meal test with ingested and infused glucose tracers and the hyperinsulinemic-euglycemic clamp procedure with glucose tracer infusion to assess the effect of 20% weight loss induced by either RYGB or BPD on glucoregulation in people with obesity (ClinicalTrials.gov number: NCT03111953).

A Step-by-Step Procedure for Bone Regeneration Using Calcium Phosphate Scaffolds: From Site Preparation to Graft Placement.

Hydroxyapatite (HA) is the main mineral component of bone and teeth. HA is often used as a bone substitute and especially in its granular form it is osteoconductive and osseointegrating as shown by many investigations in animals and humans. HA granules are used for filling bone defects, but they have poor handling qualities and retention at the surgical site, leading to graft voids between the granules and bone tissue and resulting in mechanical instability.

A Step-By-Step Technique for the Piezosurgical Removal of Fractured Implants.

With the increasing popularity of dental implants, the removal of fractured implants has become a major challenge for clinicians. Several tools can be used for the removal of osseointegrated implants; however, few of these have the characteristics of easy control, selective cutting, and rapid healing. In this study, the authors describe a step-by-step technique for the removal of osseointegrated fractured implants via multiple peri-implant osteotomies performed using a piezoelectric device and appropriate inserts.

Final overall survival analysis of a phase II trial evaluating vinorelbine and lapatinib in women with ErbB2 overexpressing metastatic breast cancer.

Lapatinib plus capecitabine (lap+cap) is approved as treatment for patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer (MBC), who have progressed on prior trastuzumab in the metastatic setting. We previously reported progression-free survival (PFS), overall survival (OS) and safety results from this open-label, multicentre, phase II study (VITAL; NCT01013740) conducted in women with HER2 positive MBC, to evaluate the efficacy and safety of lap plus vinorelbine (lap+vin), an important chemotherapy option for MBC, compared with lap+cap. In total, 112 patients were randomised 2:1 to treatment with lap+vin (N = 75) or lap+cap (N = 37).

Improving memory following prefrontal cortex damage with the PQRST method.

We tested (1) whether the PQRST method, involving Preview (P), Question (Q), Read (R), State (S), and Test (T) phases, is effective in enhancing long-term memory in patients with mild memory problems due to prefrontal cortex lesions, and (2) whether patients also benefit from a more self-initiated version of the PQRST. Seven patients with prefrontal lesions encoded new texts under three different conditions: the Standard condition, requiring to read texts repeatedly, the PQRST-Other condition, in which the experimenter formulated questions about the text (Q phase), and the PQRST-Self condition, in which patients formulated the relevant questions on their own. Compared to the Standard condition, both the PQRST-Other and the PQRST-Self condition resulted in higher immediate and delayed recall rates, as well as a higher ability to answer questions about the texts.

Prevalence of tick-borne pathogens in an urban park in Rome, Italy.

Introduction: Limited information is available about the presence of tick-borne pathogens in urban parks in Italy. To fill this gap, ticks were collected in a public park in Rome over a 1-year period and screened by molecular methods for tick-borne pathogens.

Results And Conclusion: The most abundant tick species were Rhipicephalus turanicus and Ixodes ricinus.

A phase II, randomized, multicenter study evaluating the combination of lapatinib and vinorelbine in women with ErbB2 overexpressing metastatic breast cancer.

Lapatinib is approved in combination with capecitabine for treatment of patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer (MBC) who have progressed on prior trastuzumab in the metastatic setting. Vinorelbine is an important chemotherapy option for MBC. We evaluated efficacy and safety of lapatinib plus vinorelbine, compared with lapatinib plus capecitabine, in women with HER2-positive MBC.

Seasonal dynamics of tick species in an urban park of Rome.

Regular collections were obtained in the Natural Reserve of the Insugherata of Rome during 2011 in order to obtain the tick species composition and the respective seasonal dynamics of the area. A total of 325 ticks was collected in selected sites by means of drag sampling. Among the identified species, Rhipicephalus turanicus was the most abundant (72.

Preoperative chemotherapy plus trastuzumab, lapatinib, or both in human epidermal growth factor receptor 2-positive operable breast cancer: results of the randomized phase II CHER-LOB study.

Purpose: This is a noncomparative, randomized, phase II trial of preoperative taxane-anthracycline in combination with trastuzumab, lapatinib, or combined trastuzumab plus lapatinib in patients with human epidermal growth factor receptor 2 (HER2) -positive, stage II to IIIA operable breast cancer. The primary aim was to estimate the percentage of pathologic complete response (pCR; no invasive tumor in breast and axillary nodes).

Patients And Methods: In the three arms, chemotherapy consisted of weekly paclitaxel (80 mg/m(2)) for 12 weeks followed by fluorouracil, epirubicin, and cyclophosphamide for four courses every 3 weeks.

Gemcitabine plus cisplatin versus gemcitabine plus carboplatin as first-line chemotherapy in advanced transitional cell carcinoma of the urothelium: results of a randomized phase 2 trial.

Objectives: This phase 2 randomized study compared the toxicity and assessed the efficacy of gemcitabine-cisplatin (GP) and gemcitabine-carboplatin (GC) in patients with advanced transitional cell carcinoma of the urothelium (TCC), with the main objective to demonstrate a reduction in toxicity of at least 25% in the GC arm.

Methods: A total of 110 chemonaive patients (55 per arm) with locally advanced or metastatic TCC received gemcitabine 1250 mg/m(2) on days 1 and 8 plus cisplatin 70 mg/m(2) on day 2 (GP) every 3 wk or gemcitabine 1250 mg/m(2) on days 1 and 8 plus carboplatin AUC 5 on day 2 (GC) every 3 wk for a maximum of six cycles.

Results: No differences between arms were noted in the overall toxicity profiles and any parameter of toxicity.

Cellular and pharmacogenetics foundation of synergistic interaction of pemetrexed and gemcitabine in human non-small-cell lung cancer cells.

Gemcitabine and pemetrexed are effective agents in the treatment of non-small-cell lung cancer (NSCLC), and the present study investigates cellular and genetic aspects of their interaction against A549, Calu-1, and Calu-6 cells. Cells were treated with pemetrexed and gemcitabine, and their interaction was assessed using the combination index. The role of drug metabolism in gemcitabine cytotoxicity was examined with inhibitors of deoxycytidine kinase (dCK), 5'-nucleotidase, and cytidine deaminase, whereas the role of pemetrexed targets, thymidylate synthase (TS), dihydrofolate reductase (DHFR), and glycinamide ribonucleotide formyltransferase (GARFT) in drug chemosensitivity was analyzed in cytotoxicity rescue studies.

[Drug trafficking and international law].

The production, the commerce and the use of drugs and other substances are ruled by several conventions of international law, that, at first, have had as object the production and the commerce of drugs for lawful purposes, and the measures required to prevent and to repress, at certain conditions, abuses and unlawful traffics. Just more recently, following some solicitations noticed by the International Community, and according to the concept of "well-balanced approach" described in the text, the measures introduced in this way were supported by a more incisive international movement, fit for the repression of unlawful traffics of drugs and to the adoption of suitable measures of prevention, also to avoid, at national level, sanitary, social and economical implications of the criminal phenomenon.
