ABSTRACT
Parathyroid carcinoma is an uncommon cause of primary hyperparathyroidism; however, when this condition is severe, cancer must be suspected. We report on a 28-year-old male with severe hypercalcemia, cachexia, acute pancreatitis, urolithiasis, anemia and a severe skelletal involvement with multiple fractures. The patient had a 4-cm parathyroid tumor, that was surgically excised, along with the ipsilateral thyroid lobe. During the postoperative period, he had a severe and prolonged hungry bone syndrome, with a slow recovery of fractures, with functional and anatomical sequelae in the extremities. PTH levels were adequate for the serum calcium during the 16 months of follow-up.

Background: The prevalence of periodontal diseases, gingivitis and periodontitis, is higher in diabetic patients and can have severe functional and esthetic consequences early in their lives. Aim: To evaluate the prevalence of periodontal disease in type 1 diabetics, aged between 18 and 30 years old, living in Santiago de Chile. Subjects and methods: One hundred male and female type 1 diabetics were examined. Glycated hemoglobin A1c, microalbuminuria, and fundoscopy were assessed in a sample of 52 subjects, separated in two groups according to the presence of periodontal disease. Results: The prevalence of gingivitis was 22 percent, periodontitis 41 percent. Only 37 percent of subjects were free of periodontal disease. When compared with patients without periodontal disease, in the group of patients with the disease there was a higher proportion of subjects with diabetes lasting more than 10 years (28 and 55 percent respectively) and a higher proportion of patients with chronic complications of diabetes (42 and 58 percent respectively). Conclusions: A high prevalence of periodontal diseases was observed in this sample of diabetic patients. A long history of diabetes and the presence of chronic complications were risk factors for these diseases in the analyzed sample

Subjects and methods: Serum calcium was measured in 731 subjects participating in a preventive medical examination, using an automated colorimetric method. Serum albumin was also measured. In 31 randomly chosen serum samples, calcium was also measured by atomic absorption spectrometry. Normal serum calcium ranges were established as the mean ñ 1.34 SD of the sample. Results: Mean serum calcium was 9 ñ 0.7 mg/dl, serum albumin was 4.3 ñ 0.5 g/dl and albumin corrected calcium levels were 8.7 ñ 0.7 mg/dl. Excluding lipemic sera, colorimetric calcium measurement had a correlation of 6.0 with atomic absorption spectrometry and a reliability of 17.9 percent. Using the proposed normal ranges (7.3 - 10.6 mg/dl), the frequency of hypercalcemia and hypocalcemia was 0.14 and 0.4 percent respectively. Conclusions: Most subjects found to have hyper or hypocalcemia in this study were asymptomatic
