Introduction: Hyponatremia is a commonly associated with atypical pneumonia. One of its pathophysiological mechanisms is inappropriate antidiuretic hormone secretion(SIADH). We describe the case of a patient presenting an SIADH caused by COVID19 infection.Observation: We report a case of a 70-year-old man, known to have well-controlled hypertension, with a medical history of cavum’s neoplasia treated with radiotherapy and hypothyroidism post thyroid...

High protein diets are highly satiating but hard to maintain. By understanding the mechanisms underlying these effects we may be able to identify new anti-obesity therapies. Protein is broken-down into amino acids in the gut which are detected by a series of nutrient sensors. The calcium sensing receptor (CaSR) is primarily activated by calcium ions, but is positively allosterically modulated by aromatic amino acids, especially L-phenylalanine. Sti...

Introduction: Pituitary adenomas are the most common pituitary tumours, but in 18% of cases we can find other rare tumours like: Rathke’s cleft cyst, craniopharingyomas, chordomas, meningiomas, infiltrative or infectious disease. Meningeal melanocytoma is a benign neoplasm of central nervous system, commonly located in the base of the brain, cerebellopontine angle and the pineal body, difficult to differentiate from a nonfunctional p...

Paragangliomas are rare neuroendrocrine tumours arising from extra-adrenal paraganglia of the autonomic nervous system and excess catecholamine secretion is associated with higher cardiovascular morbidity and mortality. We present the case of a 56-year old male referred to our outpatient clinic with symptoms of sympathetic-hyperactivity, including excessive sweating, palpitations and diastolic hypertension (140/100 mmHg). He had undergone...

The ability of thyroid hormones to regulate body temperature is well established. While the active hormone T3 can act peripherally to induce thermogenesis in fat and muscle, it also acts centrally in the brain to increase body temperature through the sympathetic nervous system. Most remarkably, recent studies show that T3 treatment in mice causes an elevated body temperature even at 10°C, far below thermoneutrality, suggesting that the T3 effect constitutes pyrexia rather...

Adrenocortical carcinoma (ACC) is a rare endocrine tumour with a generally poor prognosis. Mitotane is the only approved drug for treatment of advanced ACC (“palliative” setting). However, response is relatively poor with up to 20% of patients experiencing objective response (Megerle 2018). Moreover, adjuvant treatment with mitotane is frequently recommended for patients at high risk of disease recurrence after surgery (Terzolo 2007, Fassnacht 2018). Of note, mitotan...

Insulinomas are neuro-endocrine tumours of the pancreas with an incidence of 0.7-4 cases per 1,000,000 population per year. Type 1 diabetes has an incidence of >20 cases per 100,000 per population per year. Cases of insulinoma with diabetes are lower than in the general population with a type 2 preponderance. This report is the seventh of insulinoma with type 1 diabetes suggesting the latter inhibits the development of the former. A 31 year old female with a 20 year histor...
