1/4. Recognizing the faces of hypothyroidism.physicians may not recognize hypothyroidism if they rely on the stereotypical picture of the disorder. The age of the patient, stage of the disease, and other illnesses or conditions such as pregnancy can change the clinical presentation. The signs and symptoms of hypothyroidism are remarkably diverse. Instead of a single picture, physicians need a mental gallery.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
2/4. myxedema coma of both primary and secondary origin, with non-classic presentation and extremely elevated creatine kinase.myxedema coma is a rare, often fatal endocrine emergency that concerns elderly patients with long-standing primary hypothyroidism; myxedema coma of central origin is exceedingly rare. Here, we report a 37-year-old woman in whom classical symptoms of hypothyroidism had been absent. Six years earlier, she had severe obstetric hemorrhage and, shortly after, two subsequent episodes of pericardial effusion. On the day of admission, pericardiocentesis was performed for the third episode of pericardial effusion. Because of the subsequent grave arrhythmias and unconsciousness, she was transferred to our ICU. Prior to the endocrine consultation, a silent myocardial infarction had been suspected, based on the extremely high serum levels of creatine kinase (CK) and isoenzyme CK-MB. However, based on thyroid sonography, pituitary computed tomography, elevated titers of antithyroid antibodies and pituitary stimulation tests, the final diagnosis was myxedema coma of dual origin: an atrophic variant of Hashimoto's thyroiditis and post-necrotic pituitary atrophy (Sheehan syndrome). Substitutive therapy caused a prompt clinical amelioration and normalization of CK levels. Our patient is the first case of myxedema coma of double etiology, and illustrates how its presentation deviates markedly from the one endocrinologists and physicians at ICU are prepared to encounter. In addition, cardiac problems as those of our patient should not discourage from substitutive treatment (using L-thyroxine and the gastrointestinal route of absorption), if the age is relatively low.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
3/4. The rare presentation to the cosmetic and plastic surgeon of a patient with myxedema.myxedema results from hypofunction of the thyroid gland. Symptoms include dry skin, loss of and dryness of hair, mental apathy, drowsiness, and sensitivity to cold. Ocular complications associated with myxedema may be the symptoms that first prompt patients to seek a physician or cosmetic surgeon, however, though other symptoms may be present before eyelid myxedema occurs. The case reported here illustrates the value of a correct diagnosis and appropriate medical treatment, and demonstrates how surgical intervention to correct remaining eyelid problems can succeed when it is part of a comprehensive treatment plan.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
4/4. Diagnostic reasoning of high- and low-domain-knowledge clinicians: a reanalysis.thinking-aloud protocols provided by Joseph and Patel were reanalyzed to determine the extent to which their conclusions could be replicated by independently developed coding schemes. The data set consisted of protocols from four cardiologists (low domain knowledge = LDK) and four endocrinologists (high domain knowledge = HDK), individually working on a diagnostic problem in endocrinology. The two analyses agree that the HDK physicians related data to potential diagnoses more than did the LDK group and were more focused on the correct diagnostic components. However, the reanalysis found no meaningful difference between the groups in diagnostic accuracy, speed of diagnosis, or the breadth of the search space used to seek a solution. In the reanalysis, the HDK physicians employed more single-cue inference and less multiple-cue inference. The generalizability of results of protocol-analysis studies can be assessed by using several complementary coding schemes.- - - - - - - - - - ranking = 2keywords = physician (Clic here for more details about this article) |
