Predictive Value of Calcium Test for Preoperative Diagnosis of Medullary Thyroid Carcinoma in Patients With Moderately Elevated Basal Calcitonin.

Objective: Medullary thyroid carcinoma (MTC) can be very aggressive, and early diagnosis is based on routine measurement of serum calcitonin (CT) and RET genetic testing for hereditary forms. Basal serum CT (bCT) concentrations are useful in the early detection of MTC, although it is still unclear whether they can also be used for the differential diagnosis between MTC and C-cell hyperplasia (CCH). Since false-positive results can be obtained with the basal measurement of CT, a provocative test to evaluate stimulated CT (sCT) is often needed.

Case report of parathyroid carcinoma in a pediatric patient.

Parathyroid carcinoma is extremely rare in pediatric population. The authors report a case of 15-year-old girl with extremely elevated serum calcium (4.1 mmol/L) and parathyroid hormone (1170 pg/mL), with palpable neck mass.

Risk Factors for Intraoperative Hypertension during Surgery for Primary Hyperparathyroidism.

Objective: To investigate the incidence and identify risk factors for the occurrence of intraoperative hypertension (IOH) during surgery for primary hyperparathyroidism (pHPT).

Subjects And Methods: The study included 269 patients surgically treated between January 2008 and January 2012 for pHPT. IOH was defined as an increase in systolic blood pressure ≥20% compared to baseline values which lasted for 15 min.

Surgical treatment of concomitant thyroid and parathyroid disorders: analysis of 4882 cases.

The thyroid gland disease incidence in hyperparathyroidism (HPT) is higher than the incidence of thyroid disease in general population. Likewise, HPT is more frequent in patients primary admitted due to thyroid disease, than in general population. The aim of this study was to determine the incidence and clinical characteristics of concomitant HPT and thyroid disease, based on a single center experience.

Surgical treatment and dilemmas in the treatment of basal cell carcinomas with intracranial propagation.

Background/aim: Basal cell carcinoma (BCC) is one of the most common malignant skin tumors on the head in 90% of cases and is characterized by a high local infiltrating potential and destructive growth. The aim of this study was to show the characteristics of a correlation between pathohistological types of basal cell carcinoma and the size of this lesion, aggressiveness and infiltration of basal cell carcinoma, and its effect on the course of the therapy.

Methods: We analyzed 27 patients operated on for BCC that affected the scalp and the bone.
