Three types of hyperfunctioning PA were seen: prolactinoma, somatotroph adenoma, and corticotroph adenoma. Five types of hypofunctioning PA were seen: panhypopituitarism, secondary hypogonadism, growth hormone deficiency, central hypothroidism and central adrenal insufficiency. Non-functioning PA were within normal laboratory hormonal values in 2% of cases.</p><p><strong>Conclusion: </strong>Our study showed that the prevalence of PA was greater than previously reported. This increased prevalence may have important implications when prioritizing funding for research and treatment of PA.</p><p><strong>Limitations: </strong>Clustering of cases within the study region might have affected estimates and limited study sample size.</p>","PeriodicalId":93875,"journal":{"name":"Annals of Saudi medicine","volume":"36 5","pages":"341-345"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/0d/ea/asm-5-341.PMC6074317.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41160253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
