Museum samples could help to reconstruct the original distribution of Salmo trutta complex in Italy.

Partial D-loop sequences of museum specimens of brown trout and marble trout (Salmo trutta species complex) collected from Mediterranean rivers in the late 19th century were analysed to help to describe the native distribution of these species. All the individuals studied carried native haplotypes, the geographic distribution of which is consistent with published data. These results indicate that museum specimens from the 19th century could represent an opportunity to get a picture of the original genetic diversity distribution of this species complex.

Effects of consumption of whole grain foods rich in lignans in healthy postmenopausal women with moderate serum cholesterol: a pilot study.

This study aims at investigating the effect of an experimental period of intake of whole grain foods rich in lignans as part of an habitual diet on the plasma and urinary excretion of enterolignans, the biomarkers of lipid metabolism and the immunological and antioxidant status in a group of postmenopausal women with moderate serum cholesterol. A randomized double-blind crossover study was completed on 13 subjects in 12-weeks after protocol approval of an ethical committee. The subjects consumed whole grain foods high in lignans (30 g/d of breakfast cereals or biscuits, etc., 80 g/d of whole grain pasta) or refined grain foods for 4 weeks, separated by a 2-weeks wash-out period. A modest hypocholesterolemic effect (p < 0.05) of the whole grain diet was observed and the intake of whole grain products rich in lignans was also associated with an increase in urinary enterodiol excretion (p < 0.05).

Adipose tissue fatty acid composition and colon cancer: a case-control study.

PURPOSE: An increased dietary intake of fat, particularly polyunsaturated fatty acids (PUFAs), has been related to an increased risk of breast, prostate and colon cancers. Patients with and without colon cancer were tested for differences in their fatty stores composition. METHODS: The fatty acid levels were determined by gas-liquid chromatography in adipose tissue samples, subcutaneous and visceral, obtained intra-operatively from 52 colon cancer and 50 nonneoplastic abdominal disease patients. Statistical analysis was performed using one-way ANOVA, SNK test and Dunnet test. Differences in the composition of saturated, monounsaturated and polyunsaturated fatty acids, in visceral and in subcutaneous samples of colon cancer and nonneoplastic patients, were assessed. RESULTS: The sum of saturated and monounsaturated fatty acids, respectively, in visceral and in subcutaneous samples, was higher in neoplastic patients (p < 0.001). The sum of some n-6 polyunsaturated fatty acids (PUFAs), the dietary precursor linoleic acid (LA-18:2n-6), and their metabolites, gammalinolenic acid (GLA-18:3n-6) + dihomogammalinolenic acid (DGLA-20:3n-6) + arachidonic acid (AA-22:4n-6), was higher in subcutaneous fat of controls (p < 0.05). The samples from these patients had a fatty acid composition, both subcutaneous and visceral, with a higher content of alphalinolenic acid (ALA-18:3n-3) and stearidonic acid (SDA-18:4n-3) compared to neoplastic patients (p < 0.001). These had subcutaneous and visceral fat stores statistically higher in GLA, DGLA and AA (p < 0.001). Colon cancer patients had subcutaneous adipose stores higher in ALA and LA than visceral sites (p < 0.001). CONCLUSIONS: Fatty acids may be involved in colon carcinogenesis and there is a depot-specific impact on this process by visceral fat.

The effect of newer serotonin-noradrenalin antidepressants on cytokine production: a review of the current literature.

Cytokines may influence brain activities especially during stressful conditions, and elevated levels of IL-6 and C-reactive protein have been pointed out in subjects with Major Depression. If pro-inflammatory cytokines play a causative role in major depressive disorders, one would expect that antidepressants may down-regulate these cytokines or interfere with their actions, leading to improvement of depressive symptoms. Accumulating evidence has been published that antidepressants modulate cytokine production and this is particularly true for Tricyclics and Selective serotonin reuptake inhibitors (SSRIs), but the influence of newer antidepressants acting on both serotonin (5-HT) and norepinephrine (NE) such as venlafaxine, duloxetine and mirtazapine on cytokine levels has not been extensively studied. However, both pre-clinical and clinical studies examined in this review have demonstrated that newer serotonin-noradrenalin antidepressants can inhibit the production and/or release of pro-inflammatory cytokines and stimulate the production of anti-inflammatory cytokines, suggesting that reductions in inflammation might contribute to treatment response. Moreover, the results of the present review support the notion that the serotonin-noradrenalin antidepressants venlafaxine and mirtazapine may influence cytokine secretion in patients affected by MD, restoring the equilibrium between their physiological and pathological levels and leading to recovery. To date, no studies have evaluated the effect of duloxetine, the newest serotonin-noradrenalin antidepressant, on cytokine levels and therefore this should be evaluated in future studies.

[The plan for prevention of obesity of ASL RMB, Italy]. / Prevenzione dell'Obesità: l'esperienza del piano attuativo aziendale per la prevenzione dell'obesità in una ASL romana.

Lazio District, by pointing out the guidelines of the "Obesity and Overweight for Lazio District Plan" (DGR no1166, 23/12/05), enacts the "National Prevention Plan 2005-2007". The Public Health Service for Food and Nutrition has been the main player of the Plan; the District and Department of Health of the District had a technical and organizational support role. Within the development of the Plan for prevention of obesity of ASL RMB, a technical multidisciplinary group was constituted and three more programs were developed, all of them were dedicated to promotion and support of breast-feeding, prevention of obesity and overweight in childhood and adulthood. The educational activity concerning promotion and support of breast-feed ing actively involved operators from consultory rooms and hospital staff from ASL. The reports about nutritional surveillance allowed a careful analysis of the service conditions and priorities. Special criticality facets have been pointed out such as the high prevalence of overweight (31%) and obesity (7%), the habit of skipping breakfast, a low fruit and vegetables consumption, a generally sedentary lifestyle and, during the intervention, the parents' low involvement. In geriatric age cases, a high malnutrition risk both for overnutrition and undernutrition was found in the elderly groups that were checked; the diets' nutritional density as well as the physical activity aspect recover an important role in the intervention planning. Moreover the discussions with catering companies were an important aspect in order to make several target groups aware. The globally considered experience highlighted positive elements of mobilization, consensus, reorientation of activities and resources, giving proof of the significance of integration concerning specifical aims of different company services. Nevertheless, the carrying on of such activities needs resource investments in the specifical area and enlargement of activities especially for the multisector-based efforts.

A comparative, randomized, double-blind study of trazodone prolonged-release and sertraline in the treatment of major depressive disorder.

OBJECTIVES: To evaluate the efficacy and safety of trazodone prolonged-release compared with sertraline in the treatment of patients with major depression. RESEARCH DESIGN AND METHODS: A total of 122 patients aged 19-64 years were enrolled in this multicenter, double-blind, double-dummy, randomized, comparator-controlled study. Patients received 7 days of single-blind placebo treatment followed by 6 weeks of double-blind treatment with trazodone prolonged-release 150-450 mg/day (n = 62) or sertraline 50-100 mg/day (n = 60). OUTCOME MEASURES: Efficacy was evaluated by mean changes from baseline in the Hamilton Depression Rating scale (HAM-D), Montgomery Asberg Depression Rating Scale, Hamilton Anxiety Rating scale, and the Clinical Global Impression-Global Improvement/Severity scores; and by the rates of patients responding to treatment and considered to be in remission. Time to onset of efficacy and safety were assessed. RESULTS: Trazodone and sertraline were equally effective in reducing depressive symptoms and promoting remission, and had similar onset times. In the Intent-to-Treat population, there were no significant differences in favor of trazodone at study endpoint in all efficacy measures, while a statistically significant difference was detected in the Per-Protocol population on HAM-D and in the percentage of responders. Analysis of HAM-D factors (anxiety/somatization, cognitive disturbance, retardation, and sleep disturbance) indicated that sleep disturbances were significantly less evident for patients taking trazodone at study endpoint. Adverse drug reactions, mostly of mild intensity, were reported in 42% of trazodone-treated patients (mainly of the nervous system) and 43% of sertraline-treated patients (mainly gastrointestinal). One event was considered to be serious: a patient treated with trazodone 450 mg/day showed moderate anxiety/tremor/insomnia and was hospitalized. Treatment was discontinued; the patient made a full recovery. CONCLUSIONS: This study showed that after 6 weeks, trazodone and sertraline were not different in reducing symptoms of depression and in producing disease remission. Tolerability profiles reflected the differing pharmacological properties of these antidepressants. Trazodone may be a therapeutic option in the treatment of patients with major depression showing prevalent sleep disturbances.

A comparative, randomised, double-blind study of trazodone prolonged-release and paroxetine in the treatment of patients with major depressive disorder.

OBJECTIVES: To evaluate the efficacy and safety of trazodone prolonged release compared with paroxetine in the treatment of patients with major depression. RESEARCH DESIGN AND METHODS: A total of 108 patients aged 20-68 years were enrolled in this multicentre, double-blind, double-dummy, randomised, paroxetine-controlled study. Each patient received 3 days single-blind placebo treatment followed by 6 weeks double-blind treatment with either trazodone prolonged release 150-450 mg/day (n = 55) or paroxetine 20-40 mg/day (n = 53). OUTCOME MEASURES: Efficacy was evaluated by the rate of patients responding to each treatment and considered to be in remission, and by mean changes from baseline in the Hamilton Depression Rating scale scores (HAM-D), Montgomery Asberg Depression Rating Scale scores (MADRS), and Clinical Global Impression (CGI)--Severity and Global Improvement scores. Time to onset of efficacy and safety were assessed. RESULTS: Trazodone and paroxetine were equally effective at reducing symptoms of depression and promoting remission. Onset of efficacy was slightly faster for patients treated with paroxetine. Overall, there were no significant differences between the groups at endpoint in efficacy measures, and in percentage of responders (> 85%) or patients in remission (> 65%). Sleep disorders (HAM-D subset) were significantly less evident for patients in the trazodone group at the end of the study (p < 0.05). Adverse drug reactions were reported by 35% of trazodone-treated patients (mainly of the nervous system) and 26% of paroxetine-treated patients (mainly gastrointestinal), although none was considered to be serious. CONCLUSIONS: This study showed that after a 6-week period trazodone and paroxetine are not different in reducing the symptoms of depression and, in many patients, in producing the remission of the illness. The known divergence in tolerability profile of the two medications, related to their differing pharmacological properties, was also confirmed. Trazodone may be of advantage in depressed patients with sleep difficulties.

Prulifloxacin versus ciprofloxacin in the treatment of adults with complicated urinary tract infections.

INTRODUCTION: The present study was performed to evaluate the efficacy and safety of a 10-day regimen of prulifloxacin 600 mg once daily as compared to ciprofloxacin 500 mg twice daily in the treatment of patients with complicated urinary tract infections (UTIs). MATERIALS AND METHODS: 257 patients (mean age +/- SD 62.3 +/- 16.5) were enrolled and orally treated with prulifloxacin (127 patients) or ciprofloxacin (130 patients). The study was designed as a randomized, double-blind, double-dummy, controlled clinical trial. The primary efficacy parameter was the eradication of infecting strains (<10(3) cfu/ml). The clinical outcome and tolerability were also assessed. RESULTS: At baseline, the most common infecting strains were Escherichia coli (62.8%), Proteus mirabilis (7.1%) and Klebsiella pneumoniae (4.1%). At the early follow-up, the rate of patients showing successful treatment was 90.8% in the prulifloxacin group, and 77.8% in the ciprofloxacin group (p = 0.008). A positive clinical outcome was observed in 94.8 and 93.3% of prulifloxacin- and ciprofloxacin-treated patients. Both drugs were well tolerated. Two patients dropped out for treatment-related adverse events. CONCLUSIONS: The high urinary concentrations of prulifloxacin, combined with a broad-spectrum antimicrobial activity, allow its use in the empiric therapy of UTIs.

Novel anthracycline oligosaccharides: influence of chemical modifications of the carbohydrate moiety on biological activity.

Several observations highlight the importance of the carbohydrate moiety for the biological activity of antitumoural anthracyclines. Here is reported the synthesis, cytotoxicity and topoisomerase II-mediated DNA cleavage intensity of the new oligosaccharide anthracyclines 1--4 modified in the sugar residue. Evaluation of cytotoxic potency on different cell lines, resulted in quite similar values among the different analogues. On the other hand, topoisomerase II-mediated DNA breaks level was different for the various compounds, and was not related to cytotoxicity, thus supporting previous observations reported for some monosaccharide anthracyclines modified in the carbohydrate portion.

Study of the breakup under shear of a new thermally reversible water-in-oil-in-water (W/O/W) multiple emulsion.

PURPOSE: Thickening of the external aqueous phase of W/O/W multiple emulsions is essential to increase the release under shear. However, it leads to globules bursting during fabrication. To reduce this problem, we have tested a novel thermally reversible hydrogel, EMP hydrogel. This way, the corresponding multiple emulsion (EMPME) would gel only at skin temperature, which may increase the active ingredient delivery when topically applied. METHODS: Samples were sheared at different shear rates and temperatures (20, 30, and 35 degrees C) with a controlled rheometer. A granulometric analysis was then performed with a laser diffraction granulometer, to assess the break up as a function of the shear rate at the three temperatures. Conductometric measurements (CDM 230 conductometer) provided the corresponding release curves. RESULTS: As we expected, EMPME exhibited a thermally reversible behavior. Compared to a reference emulsion thickened by carbopol, this new thermo-sensitive multiple emulsion displayed higher break up and fraction released at 35 degrees C. CONCLUSION: The first thermally reversible multiple emulsion has been developed in the present work. This one presents interesting advantages: (1) an easy fabrication process with a higher entrapment yield and (2) a higher fraction released at 35 degrees C compared with the reference emulsion.

Primary eyelid plasmacytoma.

We report a case of eyelid plasmacytoma. The patient presented with a superficial lesion on the upper left eyelid, 10x7 mm in size. Histological and immunohistochemical findings were indicative of plasmacytoma with slightly abnormal sub-epidermic plasma cell infiltrates. Immunoperoxidase staining was strongly positive for intracytoplasmic kappa light chains. No infiltration by atypical plasma cells could be documented in the bone marrow biopsy and aspirate. Skeletal survey showed no osteolytic lesions or osteoporosis. The tumor on the left eyelid was surgically removed. No radiotherapy was administered.

Fibrillary glomerulonephritis and Charcot-Marie-Tooth disease.

We report the case of a young white man with Charcot-Marie-Tooth disease type 1 that began at 4 years. At 15 years, he developed proteinuria, arterial hypertension, and renal insufficiency. Renal biopsy specimens studied by electron microscopy showed deposition of nonamyloidotic microfibrils. This is the first report of fibrillary glomerulopathy associated with this neurological disorder.

Impact of litigation on senior clinicians: implications for risk management.

OBJECTIVES: To investigate the impact of litigation on consultants and senior registrars and to establish their views on methods of reducing adverse events and litigation. DESIGN: Postal survey. SETTING: Acute hospitals in the North Thames (West) Regional Health Authority. SUBJECTS: 1011 consultants and senior registrars in acute hospitals. MAIN MEASURES: Perceived causes and effects of adverse events; views on methods of reducing litigation and adverse events. RESULTS: 769 (76%) doctors responded. 288 (37%) had been involved in litigation at some point during their career; 213 surgeons (49%) and 75 (23%) doctors in the medical specialties. Anger, distress, and feeling personally attacked were common responses to litigation. Clinicians' views on reducing litigation emphasised the need for change at the clinical level. Supervision of junior staff, workload, and training in communication skills were to the fore. CONCLUSIONS: The high frequency of doctors who have experienced litigation and the emotional responses described indicate that clinicians require support at several levels. At a personal level, support can be offered to clinicians going through the litigation process or after an adverse event. Also, managerial support is needed by offering financial and practical help in correcting the factors that have been consistently identified as producing high risk situations to minimise the possibility of a reoccurrence. Accidents in medicine are, by their very nature, costly in human and financial terms and the root causes must be tackled. Recommendations are made for clinicians and risk management teams.
