4% peri-implantitis. Furthermore, when severity leveling was applied, peri-implantitis prevalence changed markedly and ranged from 14.5 to 31.0% at the subject level and from 10.0 to 22.0% at the implant level. Subgingival restoration margins were observed in 70.6% of patients for implants with PM and in 44% patients for implants with peri-implantitis. Most of the implants with peri-implantitis were with platform match (71.5%). CONCLUSIONS  Applying different thresholds to the peri-implantitis definition yielded different prevalence rates ranging from 10 to 31%. As no established diagnostic criteria are being used today, results from clinical studies may not reflect the true disease prevalence.OBJECTIVE  This study aimed to investigate growth among neonates with gastrointestinal disorders. STUDY DESIGN  Inclusion criteria included neonates with gastroschisis, omphalocele, intestinal atresia, tracheoesophageal fistula, Hirschsprung’s disease, malabsorption disorders, congenital diaphragmatic hernia, and imperforate anus born between 2010 and 2018. Anthropometrics were collected for the first 30 months, and a subgroup analysis was performed for gastroschisis infants. RESULTS  In 61 subjects, 13% developed severe growth failure within the first month. One-, four-, and nine-month weight and length z-scores were less than birth weight in all infants (p  less then  0.05). Selleck NEM inhibitor In infants with gastroschisis, a similar pattern was observed for weight z-scores only (p  less then  0.05). From birth to 15 months, head circumference z-score increased over time in all infants (p = 0.001), while in gastroschisis infants, weight, length, and head circumference z-scores increased over time (p  less then  0.05). CONCLUSION  In a cohort of infants with gastrointestinal disorders, growth failure was followed by catch-up growth.

STUDY DESIGN  This retrospective cohort study used data from the children’s database (2000-2012) of the National Health Insurance Research Database (1996-2012) in Taiwan. We included neonates who were born between 2000 and 2004 and aged less then 1 month diagnosed with and without hyperbilirubinemia. The primary outcome was physician-diagnosed ASD. At the end of 2012, multivariate Cox’s regression analysis was used to estimate hazard ratios (HRs). RESULTS  A total of 67,017 neonates were included. The neonates with hyperbilirubinemia were associated with 1.28-fold increased risk of ASD (HR = 1.28, 95% confidence interval [CI] 1.05-1.57) compared with those without hyperbilirubinemia. In subanalysis to determine how phototherapy and exchange transfusion treatment for hyperbilirubinemia were associated with ASD showed no association between treatment and ASD, suggesting the lack of a dose-response effect of hyperbilirubinemia on the risk of ASD. Boys had a nearly six-fold higher risk of ASD than girls (HR = 5.89, 95% CI 4.41-7.86). Additionally, neonates born with preterm birth and low birth weight were associated with a risk of ASD (HR = 1.46, 95% CI 1.00-2.13). CONCLUSION  We did not observe a dose-response effect of hyperbilirubinemia on ASD, but neonatal hyperbilirubinemia may be an independent risk factor for ASD if there is a residual confounding by other perinatal complications. Therefore, this study does not support a causal link between neonatal hyperbilirubinemia exposure and the risk of ASD.

Some novel data show that the expression of some microRNAs is altered in primary aldosteronism, and some of these appear to have pathogenic relevance, as well. Differences in the circulating microRNA expression profiles between the two major forms of primary aldosteronism, unilateral aldosterone-producing adenoma and bilateral adrenal hyperplasia have also been shown. Here, we present a brief synopsis of these findings focusing on the potential relevance of microRNA in primary aldosteronism. © Georg Thieme Verlag KG Stuttgart · New York.Primary aldosteronism (PA) is the most common form of endocrine hypertension. Agonistic autoantibodies against the angiotensin II type 1 receptor (AT1R-Abs) have been described in transplantation medicine and women with pre-eclampsia and more recently in patients with PA. Any functional role of AT1R-Abs in either of the two main subtypes of PA (aldosterone-producing adenoma or bilateral adrenal hyperplasia) requires clarification. In this review, we discuss the studies performed to date on AT1R-Abs in PA. © Georg Thieme Verlag KG Stuttgart · New York.Fine-needle aspiration (FNA) is not necessary in adults with nodules ≤ 1 cm without apparent extrathyroidal extension (ETE) or lymph node (LN) involvement on ultrasonography (US). In the absence of FNA and serum calcitonin (Ctn) measurement, medullary thyroid microcarcinomas (microMTC) are not diagnosed. The aim of this prospective study was to evaluate Ctn levels in adults with a low clinical risk of MTC and nodules ≤ 1 cm without ETE or LN involvement on US. A total of 506 consecutively seen adults who had nodules with two or more suspicious features were included. Patients with elevated basal Ctn underwent a calcium stimulation test and FNA. Basal Ctn was normal in 490 patients (96.8%). In the 16 patients with elevated basal Ctn, FNA revealed MTC in only one patient and MTC was not suspected in the 15 patients with elevated basal Ctn. Three patients with stimulated Ctn100 pg/ml had MTC. Ctn was undetectable 6 months after surgery in two patients with MTC. Although uncommon, even subjects without a suspicious history and with nodules ≤ 1 cm without ETE or LN involvement on US, but with suspicious findings, can have microMTC. The measurement of Ctn permits the diagnosis of these cases. © Georg Thieme Verlag KG Stuttgart · New York.
