AMH and INSL3 in testicular and extragonadal pathophysiology: what do we know?
No full textIt is commonly accepted that testicular function is prevalently regulated by the hypothalamic-pituitary-gonadal axis: The pulsatile secretion of GnRH by the hypothalamus induces pituitary expression of the two gonadotropins FSH and LH, which then stimulate Sertoli and Leydig cells, respectively, therefore regulating steroidogenesis and spermatogenesis. However, a growing body of evidence has recently suggested that other hormones act on the reproductive tract since the early phases of fetal development. Anti-Müllerian hormone and INSL3 are still largely used only for research purposes despite being increasingly recognized as markers of Sertoli and Leydig cells function, respectively

Which is first? The controversial issue of precedence in the treatment of male sexual dysfunctions.
No full textIntroduction In male sexual dysfunction (MSD), the presence of sexual comorbidities is relatively frequent. However, what is still a matter of controversy is what the first-line therapy in these patients should be. MethodsThree scientists and the editor of the Controversies section, all experts in the medical treatment of MSD, present different perspectives on the use of phosphodiesterase type 5 inhibitors (PDE5), testosterone and dapoxetine in erectile dysfunction (ED), hypogonadism, and premature ejaculation (PE). The psychological aspects are discussed by an outstanding expert in psychosexology. Main Outcome MeasureExpert opinion supported by the critical review of the currently available literature. ResultsTestosterone should be used before PDE5s in hypogonadal men with comorbid ED; PDE5s should be used before dapoxetine in PE patients with comorbid ED, and counseling should be offered to all subjects with MSD. Conclusions Although the answer to the question which should be first? is controversial in almost all MSDs, intuition, experience, and evidence should guide the choice of which treatment should be used first. This decision is highly critical in influencing the therapeutic outcome as well the patient's and couple's adherence to treatment. Jannini EA, Isidori AM, Aversa A, Lenzi A, and Althof SE.

Nonlinear Output Regulation: A Unified Design Philosophy
No full textIn this paper, we extend to the case of higher relative degree and uncertain high-frequency gain a recently proposed method for the solution of problems of output regulation for nonlinear systems. The method is applicable to systems with possibly unstable zero dynamics, in which case the problem at issue is addressed by rendering an appropriate auxiliary system stable, with a constrain on the gain. The dynamics of this auxiliary system only depend on the zero dynamics of the controlled plant, while the constraint on the gain only depends on some parameters of the exogenous input which have to be tracked. © 2010 Springer-Verlag Berlin Heidelberg
Pion-pion scattering and the decay amplitudes
No full textWe revisit the recently proposed method for the determination of the pi-pi scattering length combination a_{0}-a_{2}, based on the study of the pi0 pi0 spectrum in K+ -> pi+ pi0 pi0. In view of a precision measurement, we discuss here the effects due to smaller absorptive contributions to the K+ -> pi+ pi0 pi0 and K+ -> pi+ pi+ pi- amplitudes. We outline a method of analysis that can lead to a precision determination of a_{0}-a_{2} and is based on very general properties of the S matrix. The discussion of final-state rescattering and cusp effects is also extended to the two K_L -> 3pi coupled channels. Thanks to the present work, the theoretical error on the a_{0}-a_{2} combination extracted from the K+ -> pi+ pi0 pi0 spectrum is reduced to about 5%. A further reduction requires the evaluation of the effects arising from radiative corrections.We revisit the recently proposed method for the determination of the pi-pi scattering length combination a_{0}-a_{2}, based on the study of the pi0 pi0 spectrum in K+ -> pi+ pi0 pi0.

A case of incomplete and atypical kawasaki disease presenting with retropharyngeal involvement
No full textKawasaki disease (KD) is a childhood acute febrile vasculitis of unknown aetiology. The diagnosis is based on clinical criteria, including unilateral cervical lymphadenopathy, which is the only presenting symptom associated with fever in 12% of cases. A prompt di_erential diagnosis distinguishing KD from infective lymphadenitis is therefore necessary to avoid incorrect and delayed diagnosis and the risk of cardiovascular sequelae. Case presentation: We describe the case of a 4 years old boy presenting with febrile right cervical lymphadenopathy, in which the unresponsiveness to broad-spectrum antibiotics, the following onset of other characteristic clinical features and the evidence on the magnetic resonance imaging (MRI) of retropharyngeal inflammation led to the diagnosis of incomplete and atypical KD. On day 8 of hospitalisation (i.e., 13 days after the onset of symptoms), one dose of intravenous immunoglobulins (IVIG; 2 g/kg) was administered with rapid defervescence, and acetylsalicylic acid (4 mg/kg/day) was started and continued at home for a total of 8 weeks. Laboratory examinations revealed a reduction in the white blood cell count and the levels of inflammatory markers, thrombocytosis, and persistently negative echocardiography. Clinically, we observed a gradual reduction of the right-side neck swelling. Fifteen days after discharge, the MRI of the neck showed a regression of the laterocervical lymphadenopathy and a resolution of the infiltration of the parapharyngeal and retropharyngeal spaces. Conclusion: Head and neck manifestations can be early presentations of KD, which is frequently misdiagnosed as suppurative lymphadenitis or retropharyngeal infection. A growing awareness of the several possible presentations of KD is therefore necessary. Computed tomography (CT) or MRI can be utilised to facilitate the diagnosis
