Pharmacological manipulation of serotonin receptors during brain embryogenesis favours stress resiliency in female rats
2018
Manipulations of the serotonin transmission during early development induce long-lasting changes in the serotonergic circuitry throughout the brain. However, little is known on the developmental consequences in the female progeny. Therefore, this study aimed at exploring the behavioural effects of pre- and postnatal stimulation of the serotonergic system by 5-methoxytryptamine in adolescent female rats on behavioural reactivity and anxiety- like phenotype. Our results show that perinatal 5- methoxythyptamine decreased total distance travelled and rearing frequency in the novel enviroment, and increased the preference for the centre of the arena in the open field test. Moreover, perinatal 5-…
A 2013 European survey of clinical practice patterns in the management of Graves' disease
2014
SummaryObjective Management of Graves' disease (GD) in Europe was published in 1987. Aim of this survey was to provide an update on clinical practice in Europe, and to compare it with a 2011 American survey. Design Members of the European Thyroid Association (ETA) were asked to participate in a survey on management of GD, using the same questionnaire of a recent American survey. Results A total of 147 ETA members participated. In addition to serum TSH and free T4 assays, most respondents would request TSH-receptor autoantibody (TRAb) measurement (85·6%) and thyroid ultrasound (70·6%) to confirm aetiology, while isotopic studies were selected by 37·7%. Antithyroid drug (ATD) therapy was the …
A retrospective study of 72 cases diagnosed with idiopathic trigeminal neuralgia in indian populace
2014
Context: Trigeminal neuralgia is as a chronic, debilitating condition, which can have a major impact on quality of life. There are few reports of trigeminal neuralgia in oriental populations. Objectives: To evaluate the retrospective data of the patients diagnosed with idiopathic trigeminal neuralgia and to understanding the disorder in the Indian populace. Methods: The retrospective data of 72 patients with typical idiopathic trigeminal neuralgia regarding age of onset, gender, site of involvement, clinical presentations and treatment received during three years of the follow up was collected and analyzed. Results: In the present retrospective study, the mean age was 54.9 years; female to …
TREATMENT WITH SILDENAFIL PREVENTS IMPAIRMENT OF LEARNING IN RATS BORN TO PRE-ECLAMPTIC MOTHERS
2010
Pre-eclampsia is an important hypertensive pregnancy disorder and a main cause of maternal and fetal morbidity and mortality Children born from mothers with preeclampsia may present cognitive deficits The mechanisms leading to this cognitive impairment remain unclear and no treatments to improve it have been tested Pre-eclampsia is associated with impaired regulation of the nitric oxide 3 5 guanosine monophosphate cyclic (cGMP) pathway, which modulates some cognitive functions We hypothesized that alterations in the NO-cGMP pathway would be involved in the mechanisms leading to cognitive impairment in rats born to pre-eclamptic mothers and that treatment with sildenafil an inhibitor of the …
Perinatal high-fat diet increases hippocampal vulnerability to the adverse effects of subsequent high-fat feeding
2015
Epidemiological observations report an increase in fat consumption associated with low intake of n-3 relative to n-6 polyunsaturated fatty acids (PUFAs) in women of childbearing age. However, the impact of these maternal feeding habits on cognitive function in the offspring is unknown. This study aims to investigate the impact of early exposure to a high-fat diet (HFD) with an unbalanced n-6/n-3 PUFAs ratio on hippocampal function in adult rats. Furthermore, we explored the effects of perinatal HFD combined with exposure to HFD after weaning. Dams were fed a control diet (C, 12% of energy from lipids, n-6/n-3 PUFAs ratio: 5) or HFD (HF, 39% of energy from lipids, n-6/n-3 PUFAs ratio: 39) th…
NeXt for neuro-radiosurgery: A fully automatic approach for necrosis extraction in brain tumor MRI using an unsupervised machine learning technique
2017
Stereotactic neuro-radiosurgery is a well-established therapy for intracranial diseases, especially brain metastases and highly invasive cancers that are difficult to treat with conventional surgery or radiotherapy. Nowadays, magnetic resonance imaging (MRI) is the most used modality in radiation therapy for soft-tissue anatomical districts, allowing for an accurate gross tumor volume (GTV) segmentation. Investigating also necrotic material within the whole tumor has significant clinical value in treatment planning and cancer progression assessment. These pathological necrotic regions are generally characterized by hypoxia, which is implicated in several aspects of tumor development and gro…
Role of S-adenosyl-L-methionine in the treatment of intrahepatic cholestasis.
1990
Recent studies have established the clinical efficacy of S-adenosyl-L-methionine (SAMe) in the treatment of cholestasis associated with hepatic diseases, pregnancy and the administration of estrogen-containing oral contraceptives. In 4 clinical trials involving a total of 639 patients with cholestasis due to acute or chronic liver disease, SAMe in an intravenous dose of 800 mg/day or an oral regimen of 1.6 g/day for 2 weeks was superior to placebo in relieving the symptom of pruritus and in restoring serum total bilirubin and serum alkaline phosphatase towards normal. The drug is also effective in intrahepatic cholestasis of pregnancy (ICP), with intravenous administration of 800 mg/day for…
Water maze performance, exploratory activity, inhibitory avoidance and hippocampal plasticity in aged superior and inferior learners
2002
In 28- to 30-month-old rats, in vitro short-term and long-term potentiation (STP and LTP) were measured in area CA1 of the hippocampus in seven superior and seven inferior learners, that were selected from a pool of 40 rats based on water maze escape performance over a period of 9 days. The aim was to examine whether levels of STP and LTP could account for group differences in learning of water maze escape, spatial preference and wall (thigmotaxis)-avoidance and in short-term retention of an inhibitory avoidance task. There was no significant group difference in open-field exploration, i.e. the number of rearings. In contrast to expectation, the superior and inferior learners did not differ…

In this double-blind clinical trial 429 patients (217 terbinafine and 212 clotrimazole) were randomized to receive twice daily terbinafine 1% topical solution for 1 week followed by a vehicle application for 3 weeks, or 1% clotrimazole solution for 4 weeks. Patients were evaluated clinically and mycologically at baseline and then at weeks one, two, four (end of treatment), and eight (end of follow-up). To be evaluable the patient needed to have a positive culture for a dermatophyte and positive KOH microscopy and a clinical diagnosis of tinea pedis (interdigital type) at baseline. Effective treatment of tinea pedis was recorded in 181 of 217 (83%) of patients treated for 1 week with terbina…
Health Tecnology Assessment: bisogni formativi teorici e pratici nelle Scuole di Specializzazione in Igiene e Medicina Preventiva
2010
Objective: The aim of our study was to perform a survey of Italian graduate students (medical doctors) attending Public Health Schools, in order to assess the importance and training needs concerning Health Technology Assessment (HTA) during their public health postgraduate education. Methods: In July 2010, we sent by e-mail a questionnaire to all graduate medical students attending Public Health Schools from four Italian Regions (representing Northern, Center and Southern Italy). The questionnaire included two sections: 1) knowledge on HTA; 2) assessment of the importance of HTA training during academic public health education. Main results: Eighty-two Public Health graduate students from …
