ORBITAL PSEUDOTUMOR CAN MIMIC GRAVES’ OPHTHALMOPATHY

2016

CONTEXT: Orbital pseudotumor (OP) is a benign inflammatory process of the orbit with a large polymorphous lymphoid infiltrate, associated with fibrosis in variable amounts, localized or diffuse. Graves’ ophthalmopathy (GO) is the most common cause of proptosis, unilateral or bilateral. CASE REPORT: We report a patient with unilateral proptosis who was initially treated with antithyroid drugs for an euthyroid Graves disease, but the extension of the investigation infirmed this. The MRI findings (inflammation of fat, muscle and the left lacrimal gland) in conjunction with the biopsy infirmed the initial diagnostic and confirmed the OP. CONCLUSIONS: Orbital pseudotumor is a rare disorder that …

Depression subtyping based on evolutionary psychiatry: Proximate mechanisms and ultimate functions

2018

Major depressive disorder constitutes one of the leading causes of disability worldwide. However, it is not a unitary disease-it is a heterogeneous syndrome, with patients differing remarkably in symptom profile, pathophysiology and treatment responsiveness. Previous attempts to subtype major depressive disorder have showed limited clinical applicability. We present a classification of major depressive disorder episodes based on the proximate mechanisms that led to the original mood change that caused the depressive episode. We identify discrete depression subtypes that are induced by: 1) infection, 2) long-term stress, 3) loneliness, 4) traumatic experience, 5) hierarchy conflict, 6) grief…

MIGRAINE AND THE ROLE OF AUTONOMIC SYSTEM: A PRELIMINARY CLINICAL STUDY

2011

Mechanical activity of small and large intestine in normal and mdx mice: a comparative analysis.

1999

The aim of this study was to compare the motor pattern (recorded as changes in intraluminal pressure) of isolated duodenum and proximal colon between dystrophic mdx and normal mice. When duodenal recordings from control preparations were compared with mdx mice there was no significant difference in the spontaneous motor pattern, responses to electrical nerve stimulation or sensitivity to pharmacological agents. Colonic segments from mdx mice showed a more complex motor pattern, consisting of contractions with amplitude and frequency similar to those of controls and by additional contractions with lower amplitude and higher frequency. Moreover, 70% of the colonic preparations from mdx mice d…

Duodenal contractile activity in dystrophic (mdx) mice: reduction of nitric oxide influence.

2003

The present study was undertaken to analyse duodenal contractility in adult dystrophic (mdx) mice. The spontaneous changes of the isometric tension and the responses of longitudinal duodenal muscle to nonadrenergic, noncholinergic (NANC) nerve stimulation and to exogenous drugs were compared between normal and mdx mice. Duodenal segments from mdx mice displayed spontaneous contractions with higher frequency than normals. N omega-nitro-L-arginine methyl ester (L-NAME) increased the frequency of contractions in normals without affecting that in mdx mice. In normals, NANC nerve stimulation elicited a transient relaxation abolished by L-NAME. In mdx mice a frank relaxation was not observed, the…

Assetto territoriale e sfide della pandemia. Considerazioni sull’esperienza spagnola e tedesca

2021

Il contagio da SARS-CoV-2 ha generato una crisi sanitaria globale senza precedenti. Ciò ha riportato al centro delle riflessioni giuridiche l’antica questione della gestione dell’emergenza nello Stato di diritto, riproponendo quesiti irrisolti e nuove sfide per la tenuta dei regimi democratici contemporanei. Sotto questo profilo, il sistema federale tedesco ma anche la dimensione autonomica spagnola offrono due interessanti casi di studio sulla gestione dell’emergenza dal punto di vista dell’assetto territoriale. The SARS-CoV-2 has generated an unprecedented global health crisis. This has brought the age-old question of emergency management in the rule of law back to the centre of legal re…

Teachers’ situational physiological stress and affect

2023

Since teaching is a demanding and stressful profession, the study of teachers’ physiological stress in the classroom setting is an emerging field. In cross-sectional studies self-reported stress and affect are related, but less is known about the intraindividual relations between situational physiological stress and corresponding positive and negative affect. The aim of our study was to investigate the associations between situational physiological stress (six salivary cortisol samples per day) and self-reported situational affect (Positive and Negative Affect Schedule four times a day) among 61 Finnish primary school teachers over two workdays. We present a novel multilevel structural equa…
