Impact of group homes on the values of adjacent residential properties.

The economic impact of locating small group homes in various single-family residential neighborhoods was assessed. Sales within 229 m of 19 homes, which occurred 24 months prior and subsequent to licensing, were examined using a computer assisted mass appraisal model and an adaptive estimation procedure. The findings confirm earlier studies that refute the notion that such homes adversely impact real estate values of adjacent properties.

Hyperparathyroidism and parathyroid carcinoma.

A patient with hyperparathyroidism due to a functioning parathyroid carcinoma presented with distinctive clinical and laboratory features, including high serum calcium levels, roentgenographic signs of severe bone disease, a markedly elevated alkaline phosphatase level, a palpable cervical mass, and a high parathyroid hormone level. Treatment of parathyroid carcinoma requires en bloc resection of the ipsilateral thyroid lobe and isthmus for the primary tumor and ispilateral neck dissection for metastatic disease. Because the tumor grows slowly, recurrences should be resected to provide relief of hypercalcemia, the usual cause of death.
