Rheumatoid nodules in the thyroid bed following total thyroidectomy: a case report.

INTRODUCTION: Rheumatoid nodules occur in 30 percent of patients with active rheumatoid arthritis. Common sites include the buttocks or the extensor surface of the forearm, with one group documenting their presence in the thyrohyoid membrane. To the best of our knowledge, rheumatoid nodules have not been described in the thyroid bed. CASE PRESENTATION: We present the case of a 46-year-old Caucasian woman with active rheumatoid arthritis and Hashimoto's thyroiditis who presented with compressive neck symptoms. An ultrasound scan revealed that both lobes of her thyroid were enlarged. The right lobe measured 7.9×3.4×3.3cm and the left 8.3×3.3×3.1cm. A solitary 1.0×0.6×0.8cm nodule was seen in the right lower lobe. Her thyroid-stimulating hormone level was 4.22uU/mL (0.34 to 5.60). A total thyroidectomy was performed due to her symptoms and the possible growth of a nodule when on levothyroxine. A postoperative ultrasound scan showed no remaining thyroid tissue. The pathology revealed several small neoplasms ranging from a well-encapsulated adenoma to highly atypical follicular and papillary Hurthle cell lesions in the setting of Hashimoto's thyroiditis. Low-dose radioactive iodine (33.4mCi) was given. Four months later, our patient complained of a feeling of fullness in her neck. A solid nodule of mixed echogenicity (5.6×3.3×2.3cm) was seen in the right level VI of the neck, and solid tissue of mixed echogenicity (2.9×2.3×1.7cm) on the left. Following repeat surgery, the pathology from the right specimen showed Hashimoto's thyroiditis. The left specimen had areas of granuloma formation with fibrinoid necrosis and palisading histiocytes, consistent with the histology of rheumatoid nodules. No evidence of malignancy was seen. The patient continues to do well and remains disease-free. CONCLUSIONS: Rheumatoid nodules have not been reported in the thyroid bed. Their pathogenesis is not clear. Postoperative release of tumor necrosis factor alpha and local vascular damage may have triggered the nodule formation in this case. Rheumatoid nodules must be kept in the differential diagnosis of an enlarging thyroid in the setting of active rheumatoid arthritis. A fine-needle aspiration biopsy may show granuloma formation and be the most cost-effective initial diagnostic step, especially if there is a concern for malignancy. Early identification of these nodules will help decrease morbidity from unnecessary interventions and result in treatment that is both timely and appropriate.

Hypertension in the postpartum woman: clinical update for the hypertension specialist.

Hypertension can persist from pregnancy or present de novo in the postpartum period and continue to pose a risk to maternal well-being. These risks are magnified as many patients present after hospital discharge and go unrecognized because of decreased medical surveillance after delivery. Guidelines for the management of postpartum hypertension are lacking, often resulting in imprecise diagnoses and incorrect treatment strategies. As hypertension specialists are called upon to provide advice to obstetricians regarding the management of hypertension in the postpartum period, it becomes important for the hypertension specialist to develop expertise in the evaluation and treatment of hypertensive women during the postpartum period. The purpose of this clinical review article is to provide an approach to the management of postpartum hypertension.

Primary hyperaldosteronism associated with hypertensive emergencies.

There is growing awareness of primary hyperaldosteronism as a cause of secondary hypertension. Usually, it manifests as hypertension and hypokalemia, or as resistant hypertension. Much less often, primary hyperaldosteronism may be detected after a hypertensive emergency has developed. We highlight this association by reporting on eight patients with a clinical diagnosis of primary hyperaldosteronism whose course was complicated by a hypertensive crisis. In all patients, an elevated serum aldosterone, was accompanied by a suppressed plasma renin activity despite the presence of a hypertensive crisis. A good outcome was obtained either with laparoscopic adrenalectomy (1 patient) or with an antihypertensive drug regimen that included an antialdosterone agent (7 patients). The differential diagnosis of hypertensive emergencies should include primary hyperaldosteronism.

Blood pressure control in the hypertension clinic.

BACKGROUND: One effort to improve hypertension care in the United States is the development of the "Hypertension Specialist" program with appropriate training and certification of individual physicians. METHODS: We examined the impact of a hypertension clinic on blood pressure (BP) levels and control. RESULTS: By one year, BP declined 18/9 mm Hg, (P =.001) and BP control rates increased from 26% to 55% (P <.001) for systolic BP, from 47% to 82% (P <.001) for diastolic BP and from 18% to 52% (P <.001) for both. Age and systolic BP were significantly higher in uncontrolled patients. CONCLUSIONS: Attendance in a hypertension clinic significantly impacts BP control.

Stroke associated with alpha blocker therapy for benign prostatic hypertrophy.

Benign enlargement of the prostate is a malady of older males, reaching an estimated prevalence of 90% in patients aged over 70 years. Many of these patients are treated with alpha blockers, which can lower blood pressure significantly. We report on a 64-year-old man who developed a right hemiparesis after taking one dose of doxazosin 4 mg for prostatic symptoms. A CT scan of the brain and carotid ultrasound studies were normal. He recovered most of his neurological function within a few days. Ambulatory blood pressure monitoring on doxazosin 2 mg revealed a striking sleep blood pressure reduction.
