Hyperthyroidism after parathyroid exploration.

BACKGROUND: We hypothesized that hyperthyroidism after parathyroid exploration may be an underreported phenomenon with a course more severe than recognized previously. METHODS: We examined pre- and postoperative thyroid function and outcomes in 199 consecutive patients who, since March 2000, had parathyroid exploration for primary sporadic hyperparathyroidism (HPTH). We excluded patients with prior thyroid or parathyroid surgery, preoperative thyroid medication, concurrent total thyroidectomy, or follow-up <5 months. RESULTS: Of 125 patients with normal preoperative serum thyroid-stimulating hormone levels, 39 (31.2%) were hyperthyroid postoperatively. Mean thyroid-stimulating hormone levels (mean +/- SD) dropped with operation from 2.0 +/- 1.1 microIU/mL to 1.2 +/- 1.4 microIU/mL (P < .0001). Nineteen patients (15%) reported symptoms 1 to 2 weeks after operation. The clinical course of hyperthyroidism typically was short, but 5 patients (4%) had symptomatic hyperthyroxinemia requiring medical therapy. Hyperthyroidism was independent of age, severity of HPTH, anatomic/pathologic features, operative time, and other measures of operative difficulty, but was associated with lithium therapy, bilateral exploration, and absence of concurrent thyroid lobectomy. CONCLUSIONS: Risk of hyperthyroidism may be underappreciated after routine parathyroid surgery for HPTH. Use of lithium and degree of dissection appear contributory. Patients undergoing parathyroid exploration need counseling and surveillance for hyperthyroidism, which may be reduced by minimizing the extent of parathyroid surgery.

The management of osteoporosis following hip fracture: have we improved our care?

To determine if physicians have improved the recognition and treatment of osteoporosis in patients with an acute hip fracture, we performed a retrospective analysis of discharge data from 1995 and 2000 at the University of Pittsburgh Medical Center, a large tertiary care, academic institution. We examined patients admitted with an acute hip fracture in 1995 and 2000 and age- and sex-matched patients admitted with community acquired pneumonia in 2000. Outcomes included age, gender, race, discharge diagnoses (from ICD-9 codes) and discharge medications (from discharge summaries) in all patients. There were 136 acute hip fracture patients (mean age 73+/-18 years) in 1995, 117 acute hip fracture patients (mean age 76+/-16 years) in 2000 and 116 patients with community-acquired pneumonia (mean age 78+/-7 years). Patients admitted in 2000 with an acute hip fracture were more likely to be diagnosed with osteoporosis (18% vs. 4%, P<0.02), more likely to be discharged on calcium (17% vs. 7%, P<0.02) and more likely to be discharged on antiresorptive therapy (15% vs. 2%, P<0.001) than those admitted in 1995. Moreover, patients admitted with community-acquired pneumonia were just as likely to receive calcium, vitamin D or antiresorptive agents at the time of discharge as those with an acute hip fracture in 2000. Patients with a diagnosis of osteoporosis in 2000 were older and more likely to receive antiresorptive agents than those without a diagnosis (29% vs. 11%, P<0.05). None of the patients received a bone mineral density examination while in the hospital. Although there was an improvement in the management of osteoporosis after an acute hip fracture from 1995 to 2000, there was no difference in management of patients with hip fracture versus pneumonia in the year 2000. However, patients with a "diagnosis" of osteoporosis in 2000 were more likely to be discharged on appropriate therapeutic options. We conclude that although we have improved our care of osteoporosis for elderly in general from 1995 to 2000, patients with an acute hip fracture are not receiving any additional treatment unless they have a diagnosis of osteoporosis. Further studies are needed to determine which factors are needed to target patients for appropriate diagnosis and treatment.
