Background: Fine-needle aspiration (FNA) of adrenal masses is a method currently indicated in lesions suspected of being extra-adrenal in origin; even though its diagnostic reliability has already been determined in many studies, few have used histological examination obtained after adrenalectomy for diagnostic confirmation. Aim: To analyze the diagnostic performance of adrenal FNA in subjects with an available histological confirmation. Subjects and methods: Fifty subjects (26 benign adrenal lesions, 9 primary malignant lesions, and 15 metastatic lesions) who had undergone ultrasound (US)-guided adrenal FNA and then adrenalectomy were re-analyzed retrospectively. Results: FNA guaranteed a sensitivity of 85.7% and a specificity of 100% in all subjects; after having divided the subjects into oncologic and non-oncologic groups, the sensitivity of the test in oncologic patients (100%) increased significantly compared to non-oncologic (57.1%) with no difference in specificity (100% in both groups). Considering also non-diagnostic samples in our analysis (no.=11; 22% of all samples studied), FNA correctly diagnosed malignancy only in 75% of the cases and benignancy only in 66.6%; however, even after including nondiagnostic samples, the percentage of correct malignancy diagnosis remained significantly higher in oncologic (93.3%) than in non-oncologic patients (44.4%) without significant statistical difference between the 2 groups regarding the percentage of correct benignancy diagnosis (respectively 100% and 63.6%). Conclusions: Our study, based on histological confirmation, underlines the low discriminant value of US-guided adrenal FNA, though the method may have value in oncologic patients. ©2012, Editrice Kurtis.

A large body of in vitro evidence shows that cytokines influence the hypothalamic-pituitary-adrenal axis both in physiological conditions and in Cushing's disease (CD). In order to study in vivo the role of intra-pituitary cytokines in CD, we assayed two cytokines known for their action on the pituitary, i.e. interleukin-1 beta (IL-1β) and interleukin-6 (IL-6), and also soluble interleukin-6 receptor (sIL-6R), important for the neural activities of IL-6, in a carefully selected sample of subjects affected by CD undergoing bilateral inferior petrosal sinus sampling. Similarly to ACTH, all cytokines basally showed a higher concentration in the ipsilateral sinus compared to the controlateral one and to that of peripheral blood; after CRH infusion, both ipsilaterally and controlaterally, IL-6 and sIL-6R values increased compared to basal ones, while IL-1β increased significantly up to 5 min after CRH and then decreased significantly compared to basal values in subsequent measurements; peripherically no significant variations in the cytokines were observed after CRH. Again similarly to ACTH, the three cytokines presented a higher increase ipsilaterally than controlaterally; moreover all three interleukins in the ipsilateral sinuses showed positive and significant correlations between their basal value and that of basal ACTH. These findings allow us to hypothesize that the central production of IL-1β and IL-6 could be involved in ACTH hypersecretion which occurs in CD: more specifically, we hypothesize that these cytokines are produced directly by the corticotroph adenoma and have the task of enhancing tumoral secretion of ACTH with an autocrine-paracrine mechanism. © Springer Science+Business Media, LLC 2010.

Background: Hirsutism is defined as the presence of excessive terminal hair in androgen-dependent areas of a woman's body. Regarding this it has been suggested that Lavender and Tea tree oils may have antiandrogenic activities. Aim: To evaluate therapy based on Lavender and Tea tree oils in women suffering from mild idiopathic hirsutism (IH). Subjects and methods: A prospective, open-label, placebo-controlled, randomized study was performed: women affected by mild IH were randomly assigned to receive oil spray containing Lavender and Tea tree oils (group T) (no.=12) or placebo (group P) (no.=12) twice a day for 3 months in areas affected by hirsutism. Evaluation of hirsutism was carried out at baseline and after 3 months by Ferriman-Gallwey score and by measuring hair diameter taken from some body areas. A hematological and hormonal evaluation was carried out at baseline and after 3 months. Results: No significant variations were found in any of the hormones studied in groups T and P between baseline and after 3 months. A statistically significant decrease of hirsutism total score and of hair diameter was found in group T, while no statistically significant difference in these two parameters was observed in group P; in group T percentual reduction of hair diameter was significantly greater than in group P. Conclusions: Lavender and Tea tree oils applied locally on skin could be effective in reducing mild IH; this treatment could represent a safe, economic and practical instrument in the cure of this disease. © 2013, Editrice Kurtis.

Context: The desmopressin (DDAVP) test has been proposed to discriminate Cushing's disease (CD) from pseudo-Cushing states (PC); however, current information on its value is scarce and contradictory. Objective: The aim of the study was to assess the ability of the DDAVP test in distinguishing between these conditions, with emphasis on subjects with mild hypercortisolism. Design and Setting: We conducted a retrospective/prospective study at the Division of Endocrinology, Polytechnic University of Marche, Ancona, Italy. Patients: The study included 52 subjects with CD, 28 with PC, and 31 control subjects (CT). Intervention(s): We performed the DDAVP test and standard diagnostic procedures for the diagnosis of Cushing's syndrome. Main Outcome Measure(s): The diagnosis/exclusion of CD was measured. Results: Interpretation of the DDAVP test based on percentage and absolute increment of cortisol and ACTH did not afford acceptable values of both sensitivity (SE) and specificity (SP). CD diagnosis based on simultaneous positivity for basal serum cortisol greater than 331 nmol/liter and absolute ACTH increment greater than 4 pmol/liter and its exclusion in subjects negative for one or both measures yielded an SE of 90.3% and an SP of 91.5%. The approach was also highly effective in distinguishing PC from: 1) CD with moderate values of urinary free cortisol (SE, 86.9%; SP, 92.8%); 2) CD with moderate values of serum cortisol after dexamethasone suppression (SE, 86.6%; SP, 92.8%); and 3) CD with moderate values of midnight serum cortisol (SE, 100%; SP, 92.8%). Conclusions: Interpretation of the DDAVP test through a combination of parameters allowed effective discrimination of CD from PC, even in subjects with mild hypercortisolism.

Background: Obesity is a complex multifactorial disease, which also has an impact on quality of life. The aim of this paper is to identify the correlates of perceived health related quality of life in obese, overweight and normal weight Italians older adults. Methods. 205 subjects at the age ≥ 60 yrs. were recruited into the Division of Endocrinology of the Polytechnic University of Marche Region, Ancona (Italy). A protocol of questionnaires was constructed for data collection, and included domains such as physical activity, quality of life, socio-psychological aspects. The association of the latter variables with SF-36 Health Survey physical component (PCS-36) were evaluated in the whole sample. Multiple linear regression models were used to assess the effect of independent variables on PCS-36 and the physical subscales of SF-36. Results: PCS-36 showed a lower score in the obese and overweight subjects than the normal weight group (post-hoc test, p < 0.001 and p < 0.05 respectively). Age, gender (male), Body Mass Index, years of education, Physical Activity Scale for the Elderly (PASE) total score, Hospital Anxiety and Depression Scale anxiety, Hospital Anxiety and Depression Scale depression, number of medications prescribed and number of diseases were included in the model. Negative and significant PCS-associated variables included depression (p = 0.009), BMI (p = 0.001), age in years (p = 0.007), whereas positive and significant PCS-associated independent variables were years of education (p = 0.022), physical activity (p = 0.026). BMI was negatively associated with all the physical subscales of SF-36 (p < 0.05). Conclusions: Research funding should be invested in the study of the benefits accruing from reducing obesity in the elderly. © 2014 Giuli et al.; licensee BioMed Central Ltd. Source
