Introduction: Post-hospital syndrome (PHS) is defined as a period of vulnerability during the first 30 days after a patient is discharged from hospital, in which multiple factors come into play. Hyponatremia is the most frequent hydroelectrolytic disorder in hospitalized patients and may be related to the appearance of PHS. Objective: The objective is to estimate the prevalence of PHS that is assessed as the rate of readmissions in the first 30 days after discharge, in patients with hyponatremia. Material and Methods: It is a descriptive observational study of patients with hyponatremia who were discharged from 1 September 2010 to 2 February 2020 at the Internal Medicine Service of the Hospital University of San Juan (Alicante, Spain). Results: Of the 25 included patients, 5 (20%) were readmitted within a month of discharge, after a mean of 11.4 days (standard deviation [SD] 5.1). The overall mortality of the study was 20% (n = 5), with one case of death in the first 30 days post-hospitalization (4%). In 12 patients (48%)

In response to the case of a patient with mesenteric panniculitis (MP) and proliferative disease, we reviewed the literature on their possible association and associations with other neoplasms. MP is a non-specific chronic inflammation of the mesenteric fat, with low prevalence and unknown etiology; patients may be asymptomatic or present predominantly gastrointestinal complaints. The disease can be either primary or secondary to other pathologies, including neoplastic ones. Diagnosis is made via computed tomography (CT) and confirmed by biopsy. Currently, there is no established treatment for MP. The literature contains series of variable sample sizes, case reports, reviews of other published studies, and some series after a 5-year follow-up. Papers tend to be relatively consistent when it comes to prevalence data and clinical manifestations. However, there is still controversy regarding the role that secondary MP could play in a paraneoplastic picture. From the diagnostic point of view, the incorporation and use of positron emission tomography (PET), together with CT, has been helpful for the approach and the diagnostic focus in this field. Nevertheless, its usage and the discrimination cut point between inflammatory pathology and tumor pathology (maximum standard uptake value: SUVmax) are not clearly defined in neoplastic cases.
