Management of gestational hypothyroidism: results of a Brazilian survey

Objectives Evaluate the management of hypothyroidism in fertile-aged and pregnant women and compare these practices to the recommendations of the Brazilian Society of Endocrinology and Metabolism (SBEM) and the Latin American Thyroid Society, published in 2013. Materials and methods In the first trimester of 2014, SBEM made available to all members an electronic questionnaire based on clinical scenarios in the management of gestational hypothyroidism. The responses of 406 physicians, most of them endocrinologists, were analyzed. Results Eighty-one per cent of the endocrinologists screen all their pregnant patients for thyroid dysfunction, mostly during the pregestational period or after the first prenatal visit. Following screening, 82% of the respondents initiate treatment when TSH levels are > 2.5 mIU/L while 67% monitor their pregnant patients even if TSH was normal on first trimester screening. For hypothyroid women who are planning pregnancy, 96% of the clinicians are aware of the importance of adjusting the levothyroxine (LT4) dose as soon as pregnancy is confirmed. However, opinions diverge with respect to adjusting the LT4 dose before or after reassessing thyroid function. The most widely used tests for monitoring pregnant women in use of LT4 are TSH and free T4 (62%) or TSH alone (21%). Unanimously, the treatment goal is to achieve the target TSH level for each trimester of gestation. Conclusion The recommendations of the consensus statements are incorporated into the respondents’ clinical practice. It is noteworthy that the great majority of the clinicians favor universal screening.

Detection of cognitive impairment in the elderly by general internists in Brazil

BACKGROUND: Cognitive impairment, from mild forms to dementia, is an important social and health concern, principally among older individuals. Elderly patients are usually followed by general internists, who may overlook this condition. OBJECTIVE: Our aim was to determine whether cognitive impairment diagnosed by specialists had been previously detected by general internists. SUBJECTS AND METHODS: A total of 248 elderly individuals randomly selected from a list of outpatients seen by general internists in a public university hospital in São Paulo, Brazil, were evaluated by a geriatrician. Patients were then classified as having probable cognitive impairment or not, based on their performance on the Mini-Mental State Examination and the Informant Questionnaire on Cognitive Decline in the Elderly. Cases of probable impairment were submitted to routine laboratory investigation, brain computed tomography, and neuropsychological evaluation. The final diagnoses were established by a consensus panel comprising two neurologists and the geriatrician who evaluated the patients using all available data. General internists' files for all cognitively impaired cases and for a selected sample of individuals without cognitive impairment were checked for any record of cognitive complaints or decline. RESULTS: Forty-three patients were classified as demented (n = 21) or as cognitively impaired but not demented (n = 22). The evaluation of the general internists' files revealed that information on cognitive complaints or decline was recorded for seven (16.3 percent) of the 43 patients with dementia or cognitive impairment without dementia. CONCLUSIONS: General internists seldom detected cognitive decline in elderly patients in Brazil. Further studies should be conducted to elucidate the reasons for this low rate of detection.
