    Abstract We present a mathematical study for the development of Multiple Sclerosis in which a spatio-temporal kinetic model describes, at mesoscopic level, the dynamics of a high number of interacting agents. We consider both interactions among different populations of human cells and motion of immune cells, stimulated by cytokines. Moreover, we reproduce the consumption of myelin sheath due to anomalously activated lymphocytes and its restoration by oligodendrocytes. Successively, we fix a small time parameter and assume that the considered processes occur at different scales. This allows to perform a formal limit, obtaining macroscopic reaction-diffusion equations for the number densities with a chemotaxis term. A natural step is then to study the system, inquiring about the formation of spatial patterns through a Turing instability analysis of the problem and basing the discussion on microscopic parameters of the model. In particular, we get spatial patterns oscillating in time that may reproduce brain lesions characteristic of different phases of the pathology.

    Abstract Phyllodes tumor is an extremely rare tumor of the breast. It occurs in females in the third and fourth decades. The difficulty in distinguishing between phyllodes tumors and benign fibroadenoma may lead to misdiagnosis. Lymph node involvement is rarely described in phyllodes tumors; for this reason, sentinel node biopsy may be warranted. We present a case of a 33-year-old woman affected by huge tumor of the right breast with ulceration in the skin with a rapid tumor growth and with omolateral axillary metastasis.

    Abstract Gynecomastia is characterized by benign progressive enlargement of the male breast. A pharmacologic origin is identified in 10-20% of cases. Several case reports have associated this condition to the use of statins. However, to our knowledge, no case of rosuvastatin-induced gynecomastia has been reported in the literature. We describe a 57-year-old man who developed bilateral gynecomastia after 2 months of rosuvastatin therapy. After switching to a different statin, atorvastatin, his symptoms resolved within 1 month. Use of the Naranjo adverse drug reaction probability scale indicated a possible relationship between the patient's development of gynecomastia and rosuvastatin therapy. The relatively strong effect of rosuvastatin on inhibiting steroidogenesis might have explained why our patient's gynecomastia occurred only with this agent. Clinicians should be aware of the possibility of adverse endocrine reactions when statins are prescribed, including newer agents such as rosuvastatin.

    Abstract The development and validation of a self-reported measure of obesity-related quality of life, the Obesity Related Well-Being (ORWELL 97), were undertaken to examine the intensity and the subjective relevance of physical and psychosocial distress. The questionnaire was validated in a sample of 147 obese patients (99 females, 48 males). The Eating Disorder Examination 12.0D interview, a structured diagnostic interview for DSM-III-R (DSM-IV criteria for binge eating disorder), Beck Depression Inventory, Binge Eating Scale, and the State-Trait Anxiety Inventory 1 and 2 scales were also applied. Internal consistency and test-retest reliability were satisfactory. Factor analysis allowed the identification of two subscales: ORWELL 97-1 related to psychological status and social adjustment, and ORWELL 97-2 related to physical symptoms impairment. Obese female patients showed a lower quality of life, and the severity of obesity appeared to interfere with physical functioning rather than psychological status and social adjustment. The ORWELL 97 questionnaire appears to be a simple and reliable measure of obesity-related quality of life, which can be used in current clinical practice.

    Abstract Background: The aim of this pilot trial was to study the feasibility of sentinel node percutaneous preoperative gamma probe-guided biopsy as a valid preoperative method of assessment of nodal status compared to surgical sentinel lymph node biopsy.
    Material/methods: This prospective study enrolled 10 consecutive patients without evidence of axillary lymph node metastases at preoperative imaging. All patients underwent sentinel node occult lesion localization (SNOLL) using radiotracer intradermic injection that detected a "hot spot" corresponding to the sentinel node in all cases. Gamma probe over the skin detection with subsequent ultrasonographically guided needle biopsy of the sentinel node were performed. The percutaneous needle core histopathological diagnosis was compared to the results of the surgical biopsy.
    Results: Preoperative sentinel node identification was successful in all patients.
    Conclusions: The combination of preoperative gamma probe sentinel node detection and ultrasound-guided biopsy could represent a valid alternative to intraoperative sentinel node biopsy in clinically and ultrasonographically negative axillary nodes, resulting in shorter duration of surgery and lower intraoperative risks.

    Abstract Objective: Aim of this study was the assessment of the prevalence of eating disorders, and of eating disorder symptoms, in obese patients with type 2 diabetes, compared to non-diabetic subjects.
    Design: Three samples of individuals were studied: a series of 156 (76 male, 80 female) overweight and obese type 2 diabetic patients, aged 30-65 y, with a body mass index (BMI)>28 kg/m(2) (DM); a series of 192 (20 male, 172 female) obese (BMI>30 kg/m(2)) non-diabetic patients aged 30-65 y seeking treatment for weight loss (OC); and a non-clinical sample of 48 (22 male, 26 female) obese (BMI>30 kg/m(2)) subjects aged 30-65 y selected from the lists of two general practices (OP). Eating behavior was assessed using the Eating Disorder Examination (EDE 12.0D).
    Results: The prevalence of Binge Eating Disorder was lower than 5% in all the three samples. Median EDE scores in females were significantly higher in OC (3.0) and OP (3.4) than in DM (1.7), while diabetic patients showed higher scores on Restraint than both non-diabetic samples. Among diabetic patients, a significant correlation of EDE scores with HbA(1)c was observed.
    Conclusions: Type 2 diabetes is unlikely to induce relevant eating disturbances in obese patients, apart from an increase in restraint. Abnormalities of eating attitudes and behavior are associated with an impairment of metabolic control.

    Abstract Clonidine, an imidazoline derivative, is an antihypertensive agent which reduces sympathetic tone by acting in the central nervous system to stimulate alpha-2 adrenoceptors. There is evidence that dopamine and norepinephrine modulate the secretion of GH. Stimulation of GH release is a well-known effect of clonidine in man. Obesity is characterized by an impairment of GH release in response to various stimuli. The aim of this work is to study GH release in response to alpha-2 adrenoceptors stimulation by clonidine in obesity. 12 volunteer obese subjects were studied. 10 normal weight subjects, sex and age matched, were controls. The GH responsiveness was tested with a single oral dose of clonidine (0.15 mg). Blood was sampled for GH radioimmunoassay at 0', 30', 60', 90', 120', 150', 180'. Serum GH basal levels were not significant different in obese subjects compared to controls. In obese subjects, no significant changes occurred in blood GH concentration after clonidine. In normal weight controls, instead, a significant increase of GH values was reached at 90' (P less than 0.05) and at 120' (P less than 0.05) after clonidine. The impairment of GH release after clonidine in obese subjects might be in a reduced serotonin release or in a failure of the hypothalamic-pituitary system to stimulate plasma GH caused by a diminished GH releasing factor stimulatory effect or by an excessive endorphin or somatostatin secretion in obesity.

    Abstract Background: Results of a clinical trial recently completed in the United States indicate that administration of tamoxifen (20 mg/day) to women at risk can reduce breast cancer incidence by approximately 50% but is associated with an increased risk of developing endometrial cancer and venous thromboembolic events. Since these adverse effects may be dose related, we investigated the effect of tamoxifen on several biomarkers when the drug was given at doses lower than those currently in use.
    Methods: In two sequential experiments, 127 healthy hysterectomized women aged 35-70 years were randomly assigned to one of the following four treatment arms: placebo (n = 31) or tamoxifen at 20 mg/day (n = 30) (first experiment); or tamoxifen at 10 mg/day (n = 34) or tamoxifen at 10 mg/ alternate days (n = 32) (second experiment). Baseline and 2-month measurements of the following parameters were compared: 1) total cholesterol (primary end point) and other surrogate markers of cardiovascular disease, e.g., low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, and lipoprotein(a); 2) blood cell count; 3) fibrinogen; 4) antithrombin III; 5) osteocalcin; and, 6) in a subgroup of 103 women, insulin-like growth factor-I (IGF-I), a possible surrogate marker for breast cancer.
    Results: After adjustment for the baseline values, there were reductions in circulating levels of total cholesterol and IGF-I of the same magnitude in all three tamoxifen treatment arms. A similar pattern was observed for most of the other parameters. In the placebo arm, fibrinogen level, which showed a decrease, was the only parameter exhibiting change.
    Conclusions: Up to a 75% reduction in the conventional dose of tamoxifen (i.e., 20 mg/day) does not affect the activity of the drug on a large number of biomarkers, most of which are surrogate markers of cardiovascular disease. This study was hypothesis generating, and larger studies are warranted to assess the efficacy of tamoxifen at low doses.
