Acute adrenal insufficiency associated with tuberculous vertebral osteomyelitis and lymphadenopathy: case report.

A 51-year-old man developed anorexia, dizziness, nausea, vomiting, and weight loss. He had orthostatic hypotension, hyponatremia, hyperkalemia, and hypocortisolemia, and the diagnosis of adrenal insufficiency was made. Magnetic resonance imaging (MRI) showed asymmetrically enlarged adrenal glands. Biopsy of a hypoechoic, enlarged, inguinal lymph node showed caseating granulomas. Lumbar MRI showed vertebral body height loss and abnormal signal in L1 and L2; vertebral biopsy showed chronic, necrotic, caseating granulomatous inflammation consistent with tuberculous osteomyelitis. Clinical improvement occurred with isoniazid, rifampicin, pyrazinamide, and corticosteroids. The differential diagnosis of adrenal insufficiency should include tuberculosis, especially in geographic regions where tuberculosis is endemic.

A woman with thyrotoxicosis- and hyperemesis gravidarum-associated Wernicke's encephalopathy.

Although hyperthyroidism arising from primary thyroid disease is rare in pregnancy, transient gestational hyperthyroidism is not uncommon. This condition can be associated with hyperemesis gravidarum (HG), and Wernicke's encephalopathy. We present the case of a woman with toxic nodular goiter complicating HG-associated Wernicke's encephalopathy. A 38-year-old Caucasian woman, who had received a diagnosis of hyperthyroidism and HG early in her pregnancy, had intrauterine fetal death at Week 16 of gestation. One day after undergoing therapeutic abortion, she was admitted to our clinic with persistent thyrotoxicosis, nausea, and vomiting. A toxic thyroid nodule was detected. She was given antithyroid medication, total parenteral nutrition. On Day 10 of hospitalization, she developed ataxia, aphasia, and somnolence. Cranial magnetic resonance imaging showed increased bilateral thalamic signalization. She was given a diagnosis of Wernicke's metabolic encephalopathy, for which she received thiamine and multivitamin preparations. She responded dramatically on the second day of thiamine therapy. Her consciousness improved rapidly and she began to speak. Her muscle tone was slightly weak and she had paresthesias in both legs. Absorption of thiamine may be particularly impaired in pregnant women with hyperemesis and hyperthyroid disease. Wernicke's encephalopathy should be considered in hyperthyroid women with HG who develop neurological abnormalities.

Higher metabolic risk with National Institutes of Health versus Rotterdam diagnostic criteria for polycystic ovarian syndrome in Turkish women.

BACKGROUND: Polycystic ovary syndrome (PCOS) is a heterogeneous disease with well-established metabolic abnormalities in women of reproductive age. There are various diagnostic criteria to define and establish PCOS. However, data conflict regarding the optimal diagnostic criteria for PCOS and its metabolic consequences. We have evaluated the clinical, endocrine, and metabolic features between main PCOS phenotypes according to different diagnostic criteria. METHODS: In this prospective, case-control study, 175 consecutive women with PCOS, 41 ovulatory women with idiopathic hirsutism, and 109 healthy, nonhirsute, ovulatory controls were enrolled. The following diagnostic criteria were assessed: Hirsutism; ovulatory function; ovarian sonography; gonadotropin, testosterone, dehydroepiandrosterone (DHEA), 17-hydroxyprogesterone, fasting insulin, and lipid levels; oral glucose tolerance test; homeostasis model assessment for insulin resistance (HOMA-IR); body mass index (BMI); waist circumference; and the presence of metabolic syndrome. RESULTS: Of the 175 women meeting the Rotterdam criteria for PCOS, 121 (69%) had both androgen excess and ovulatory dysfunction, thus also meeting the National Institutes of Health (NIH) criteria. The other 54 (31%) had either androgen excess or ovulatory dysfunction. Women meeting the NIH criteria had the largest mean BMI, waist circumference, and HOMA-IR score; the highest mean testosterone, DHEA, triglyceride, and fasting insulin levels; the lowest mean progesterone level; and the greatest prevalence of insulin resistance (HOMA-IR score >3) among the groups. CONCLUSIONS: The NIH criteria identify women at high risk for insulin resistance and metabolic syndrome. The Rotterdam criteria include women who have less severe metabolic implications.
