The implant survival rate was 100%. The prosthetic success was 93.3%.
CSS seems to represent a viable option for capturing accurate intraoral digital impressions for the fabrication of precise long-span implant-supported restorations.

We conducted a population-based case-control study (145 cases and 405 controls). We used logistic regression models to estimate adjusted odds ratios (OR) and their 95% confidence intervals (CI). Two-way interactions were assessed on both multiplicative and additive scales. Current smoking (OR = 11.6, 95% CI = 6.7-20.1), drinking more than five glasses of alcohol per day (OR = 2.7, 95% CI = 1.2-4.7), and oral infection with High-risk HPV (OR = 2.4, 95% CI = 1.1-5.0) were significantly associated with HNSCC. The combined exposure to tobacco and alcohol produced a significant synergistic effect on the incidence of HNSCC. Oral infection with High-risk HPV increased the risk of HNSCC in never smokers and nondrinkers. The effects of tobacco, alcohol, and of the combined exposure of tobacco and alcohol were substantially lower in HPV-positive than in HPV-negative HNSCC. This is the first case-control study to investigate the role of tobacco smoking, alcohol drinking and oral HPV infection in an Afro-Caribbean population. Although each of these risk factors has a significant effect, our findings indicate that tobacco and alcohol play a less important role in Hr-HPV-positive HNSCC. Further investigations are warranted notably on the interaction of these three risk factors by cancer site.
We identified a novel de novo SCN2A variant (M1879T) associated with infantile-onset epilepsy that responded dramatically to sodium channel blocker antiepileptic drugs. We analyzed the functional and pharmacological consequences of this variant to establish pathogenicity, and to correlate genotype with phenotype and clinical drug response.
The clinical and genetic features of an infant boy with epilepsy are presented. We investigated the effect of the variant using heterologously expressed recombinant human Na
1.2 channels. We performed whole-cell patch clamp recording to determine the functional consequences and response to carbamazepine.
The M1879T variant caused disturbances in channel inactivation including substantially depolarized voltage dependence of inactivation, slower time course of inactivation, and enhanced resurgent current that collectively represent a gain-of-function. Carbamazepine partially normalized the voltage dependence of inactivation and produced use-dependent block of the variant channel at high pulsing frequencies. Carbamazepine also suppresses resurgent current conducted by M1879T channels, but this effect was explained primarily by reducing the peak transient current. Molecular modeling suggests that the M1879T variant disrupts contacts with nearby residues in the C-terminal domain of the channel.
Our study demonstrates the value of conducting functional analyses of SCN2A variants of unknown significance to establish pathogenicity and genotype-phenotype correlations. We also show concordance of in vitro pharmacology using heterologous cells with the drug response observed clinically in a case of SCN2A-associated epilepsy.

In this study, we aim to present the clinical outcomes of radiotherapy (RT) in clinical pelvic lymph node-positive prostate cancer (cN1) patients. this website We also analyze the prognostic factors with focus on RT dose escalation to metastatic lymph nodes (LN).
We retrospectively analyzed the data from cN1 patients who were treated with definitive RT and androgen deprivation therapy (ADT) between June 2004 and February 2016. All patients received localized irradiation to the prostate region and whole pelvis irradiation. Some patients received intensity-modulated radiation therapy with RT dose escalation to metastatic LN. Univariate analyses using log-rank test were performed to find prognostic factors between patient subgroups.
Fifty-one consecutive patients were identified. The median follow-up period for all patients was 88 (range 20-157) months. Primary Gleason pattern and LN RT dose were statistically significant prognostic factors for relapse-free survival (RFS) and distant metastasis-free survival (DMFS). Especially, RT dose escalation (60Gy or more) to metastatic LN significantly improved RFS and DMFS compared with standard dose RT (4-year RFS 90.6% vs 82.1%, 7-year RFS 90.6% vs 58.0%, P=.015; 4-year DMFS 90.6% vs 82.1%, 7-year DMFS 90.6% vs 62.8%, P=.023). The following factors were all statistically significant for biochemical relapse-free survival (BRFS) T stage, LN RT dose, local RT dose, and ADT duration period. Any significantly different toxicity was not seen for each LN or local RT dose except for the incident rate of grade 2 or more acute urinary retention, which was significantly higher in the higher LN RT dose (60Gy or more) group by the Chi-square test.
RT dose escalation to metastatic LN in cN1 patients improves BRFS, RFS, and DMFS at 4 and 7years, without increasing severe adverse events.

Whether patients with end-stage renal disease (ESRD) have a higher risk of idiopathic polyneuropathy (IPN) than those without ESRD remains unclear. We hypothesised that carpal tunnel syndrome (CTS) is a prodrome of IPN in patients with ESRD.
Data were collected from the Taiwan National Health Insurance research database (NHIRD) for the 2000-2011 period. Two matching strategies, age- and sex-matching and propensity matching, were used, which yielded 2596 age- and sex-matched patients with ESRD and 2210 propensity-matched patients with ESRD. The comparison cohort was chosen in a 14 ratio for the age- and sex-matched method and in a 11 ratio for the propensity-matching method. The primary outcome was the incidence of IPN. Cox proportional hazards modelling was used.
In the age- and sex-matched cohort, the IPN incidence was 7.64 and 2.88 per 1000 person-years for the ESRD and controls cohorts, respectively. After we adjusted for age, sex, comorbidities and medications relative to controls, having ESRD was significantly associated with increased risk of IPN (hazard ratio [HR]=2.
