Falls could cause serious injuries in this vulnerable patient population and also lead to poor health outcomes such as increased morbidity, mortality and healthcare costs. The objective of this study is to characterize falls in hospitalized elderly people and analyze the implication of polypharmacy and inappropriate prescription of medications in a University Hospital in Argentina.Materials and methods: Descriptive, observational, retrospective study.Results: A sampling 226 patients was taken, the mean age was 74.7 SD: 12.9, range 69-91. The total number of falls was 237 (9 patients suffered more than one fall). Falls are associated with several factors including polypharmacy, cognitive status, advanced age, female sex, and inappropriate prescription of medications.Discussion: Incidents of falls are frequent, preventable and multi-causal. Some factors such as polypharmacy, cognitive impairment, among others, would be associated with its occurrence; the published literature confirms these concepts.","PeriodicalId":18419,"journal":{"name":"Medicina-buenos Aires","volume":"85 3","pages":"543-549"},"PeriodicalIF":0.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144512130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Echocardiograms were performed at 6, 12 and 18 months' post-transplantation. The mechanisms of tricuspid regurgitation described were atrial dilatation or bi-atrial technique, multiple endomyocardial biopsies, right ventricular dilatation and dysfunction, previous pulmonary hypertension and mismatch of the recipient cavity with the transplanted organ.Results: A total of 234 patients were included. The incidence of significant tricuspid regurgitation from 6 months post-transplantation was 12.8%. Right ventricular dilatation and dysfunction was the most prevalent mechanism in 67%, mismatch 17%, organic valve lesion and previous pulmonary hypertension 7% and atrial dilatation 3%. The 40% of patients who had right ventricular dysfunction also presented left ventricular dysfunction.Discussion: The incidence of tricuspid regurgitation in heart transplant patients was 12.8% during the follow-up.

Increased serum phosphate is a rare finding in this pathology. This hyperphosphatemia results from increased phosphate reabsorption in the proximal renal tubule via sodium-phosphate cotransporter type IIa: an effect mediated by insulin-like factor 1 (IGF-1) consequent to excess GH. We present the clinical case of a 66-year-old woman with persistent hyperphosphatemia 4.8 ng/dl (VN: 2.5-4.5) with elevated tubular phosphorus reabsorption (TPR) 95% (VN: 85-94) with subtle features of acromegaly. Acromegaly was diagnosed by IGF1 measurements and oral glucose tolerance test with GH measurement (OGTT/GH). In search of the source of GH hypersecretion, a pituitary MRI was requested, and the pituitary microadenoma was evident only in the third year of follow-up.

Conflicting or discordant results of interpretation of multiple variants in GLA were reported in literature. The aim of this article is to report the spectrum of GLA variants in Argentine population, as well as the revised interpretation of variants classification. Moreover, we intend to find a possible correlation between biochemical parameters, clinical manifestations and genetic variants of adult male Fabry patients that could be of help for interpretation of variants.Materials and methods: Blood samples from patients with clinical suspicion of Fabry disease were evaluated for specific laboratory tests: alfa-galactosidase A enzyme activity, LysoGb3 and GLA genetic test.Results: There are 44 males with pathogenic GLA variants which showed deficient enzyme activity. Among them, thirty-two presented the classic phenotype (72%) and twelve the late onset clinical features (28%). Mean percentage of enzyme activity was 0.9% for classical patients and 3.2% for later onset ones. LysoGb3 values were increased in all males, with classic patients showing considerable higher values than that of late onset.Discussion: Our results showed that the combined analysis of the clinical picture, leukocyte enzyme activity, globotriaosylsphingosine concentration and a detailed exhaustive study of the genetic variant lead to a definite diagnosis in those cases previously interpreted as of unknown significance, together with a revised interpretation of the phenotype.","PeriodicalId":18419,"journal":{"name":"Medicina-buenos Aires","volume":"85 2","pages":"322-330"},"PeriodicalIF":0.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143803734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
