    Papillary thyroid carcinoma (PTC) is the most common endocrine malignancy, with a steadily increasing incidence in the last few decades worldwide. The predisposition to developing this carcinoma by the heterozygous state of rs2910164 within the precursor of the miR-146a has been reported, but recently not confirmed. Interestingly, on the same chromosome, almost 50 kb separate the pre-miR-146a from the pituitary tumor-transforming gene 1 (PTTG1), a proto-oncogene involved in several tumors, including thyroid cancers. In this study, we analyzed, using a case–control design, the genetic association between PTC and the genomic region encompassing pre-miR-146a rs2910164 and PTTG1 rs1862391 and rs2910202. We enrolled 307 affected patients and 206 healthy controls. The possible presence of thyroid nodules in controls was excluded by ultrasonography. All the cases were submitted to single- nucleotide polymorphism (SNP) genotyping of pre-miR-146a and PTTG1, and risk association analyses were carried out. The genotypic and allelic frequencies of pre-miR-146a rs2910164 were not statistically different in the patients and controls, and this SNP was not in linkage disequilibrium with the investigated PTTG1 SNPs. Consistently, meta-analyses, the first including all the affected cases published to date, did not confirm the previously reported association of the heterozygous CG genotype with PTC. The PTTG1 SNPs exhibited the same allelic frequency in the patients and controls and were not associated with the disease. In conclusion, in a well-selected Italian population, neither pre-miR-146a rs2910164 nor PTTG1 rs1862391 and rs2910202 were found to be associated with the risk of developing PTC

    Serum calcium to phosphorous ratio (Ca/P) as a simple, inexpensive screening tool in the diagnosis of primary hyperparathyroidism (PHPT)

    Background PHPT is often overlooked/underdiagnosed. Several strategies (biochemical markers alone or combined in complex algorithms) have been investigated to easily diagnose/screen PHPT, but PHPT diagnosis remains challenging at present, especially in asymptomatic patients. As serum calcium (Ca) and phosphorous (P) are inversely related in PHPT, the Ca/P ratio could be a good candidate tool for PHPT diagnosis. Surprisingly, no literature data on Ca/P ratio are available, despite they are very simple biochemical measurements largely available in any clinical lab setting. Aim To investigate the Ca/P ratio diagnostic value in the diagnosis of PHPT. Methods Data retrospectively obtained from review charts of 97 patients with documented PHPT (69 females; 28 males) [16 (17%) with severe hypercalcemia (O12 mg/dl); 44 (45%) mild hypercalcemia, 36 (38%) normocalcemic PHPT (NCHPT)] were compared with those of 96 controls (C) (44 females; 52 males). Exclusion criteria: age !18 years, severe chronic diseases, cancer, bone metabolic diseases, use of medications affecting serum Ca. Biochemical measurements: PTH, Vitamin D, serum Ca, P, albumin, and creatinine. Normal ranges: PTH (15–88 pg/ml), Ca (8.5–11 mg/dl), P (2.5–5.1 mg/dl). SPSS 19.0 and SigmaPlot 11.0 were used for statistics (group comparisons, ROC curves, cutoffs performance). Results Ca and PTH were significantly higher in PHPT [(Ca median:11; min-max:9.4– 15.5); (PTH 135.2; 57.6–1748)] than C [(Ca 9.4; 8.3–10.2); (PTH 32.1; 14–106.1) (P!0.0001). P was significantly lower in PHPT (2.4; 1.4–3.9) than in C (3.5; 2.1– 4.5) (P!0.0001). Ca/P ratio was significantly higher in PHPT than in C. ROC curves analyses identified a cutoff of 3.5 for both Ca/P ratio and Ca/P ratio obtained by using albumin corrected-Ca. The sensitivity and specificity were 86 and 87%, respectively for Ca/P ratio and 89 and 93%, respectively for corrected Ca/P ratio (P!0.0001). The diagnostic value of Ca/P ratio performed better than PTH and Ca used alone or in combination. Conclusions Ca/P ratio is a valuable highly sensitive, highly specific tool for the diagnosis of PHPT. Since Ca/P is simple to obtain, easily accessible in every clinical and lab setting worldwide, and inexpensive even when used in large sample size of patients, this diagnostic tool could be useful for screening PHPT, especially in patients accessing emergency rooms or in the general practitioner setting
