Comparative Study
Time to calcitonin normalization after surgery for node-negative and node-positive medullary thyroid cancer.
It remains unclear when postoperative serum calcitonin levels should be measured in patients with medullary thyroid cancer (MTC) and, specifically, whether this decision should be based on the preoperative calcitonin level or nodal status. ⋯ Calcitonin levels typically normalize within 1 week; and within a fortnight in those with node-positive MTC and preoperative calcitonin levels of 500·1-1000 pg/ml. With node-positive MTC and preoperative calcitonin levels exceeding 1000 pg/ml, and with more than ten nodal metastases, calcitonin normalization takes longer.

Comparative Study Observational Study
Population-based study of outcomes following an initial acute diverticular abscess.
Studies examining long-term outcomes following resolution of an acute diverticular abscess have been limited to single-institution chart reviews. This observational cohort study compared outcomes between elective colectomy and non-operative management following admission for an initial acute diverticular abscess. ⋯ Observation without elective colectomy following resolution of an initial diverticular abscess is a reasonable option with lower healthcare costs than operation.
