In conclusion, we report the case of tunneled hemodialysis catheter-related complete obstruction of the right brachiocephalic vein in a lupus nephritis patient undergoing hemodialysis. Clinicians should be aware of this potential complication when tunneled hemodialysis catheters are used and consider the next vascular access type before a tunneled hemodialysis catheter has been indwelled for the long term.Purpose To evaluate whether ‘invisible’ liver tumors on CT can be treated by stereotactic radiofrequency ablation (SRFA) using fusion of pre-ablation MRI.Methods In this retrospective case-control study, 60 patients (14 with Hepatocellular carcinoma (HCC) and 46 with metastatic liver tumors) with CT ‘invisible’ lesions underwent SRFA using MRI-fusion between June 2005 and June 2018 (‘fusion group’). For comparison, 60 patients who underwent SRFA without image fusion were selected using nearest neighbor propensity score matching (‘control group’). Endpoints consisted of local tumor control, safety, overall and disease-free survival.Results Major complications occurred in 6/69 ablations (8.7%) in the fusion group and in 6/89 ablations (6.7%) in the control group (p = 0.434). Primary technical efficacy rate (i.e., successful initial ablation) was 96.6% (28/29) for HCC and 97.9% (166/170) for metastatic disease in the fusion group and 100% (33/33) and 93.3% (184/194) in the control group, respectively (p = 0.468 and 0.064). Local recurrence (LR) was observed in 1/29 (3.5%) HCCs and in 6/170 metastases (4.0%) in the fusion group and 1/33 (3.0%) and 21/196 (10.7%) in the control group, respectively. The LR rate of metastasis in the control group was significantly higher (p = 0.007), although differences in OS and DFS did not reach statistical significance.Conclusions Image fusion using pre-procedural MRI allows for ablation of CT-‘invisible’ liver tumors that are otherwise untreatable. Moreover, local oncological control was higher in metastatic liver tumors versus matched controls which suggests it could be useful tool for all stereotactic radiofrequency ablation procedures.Background Gonadotropin-releasing hormone (GnRH) analogs represent the treatment of choice in patients with central precocious puberty (CPP). Recently, GnRH analogs that can be administered every 3 months have been developed and appear to be as safe and effective as one-monthly formulations. However, there are limited data regarding its long term safety and efficacy profile. We aimed to evaluate the long-term safety and efficacy treatment of CPP with GnRH analogs every 3 months. Methods We prospectively studied all patients who were diagnosed with CPP in our center between January 2015 and December 2019. All patients were treated with intramuscular leuprolide acetate 11.25 mg every 3 months. Results Twenty-four patients with CPP were included in the study. Mean follow-up was 3.1 years. Height gain ranged between 4 and 6 cm. Bone mineral density (BMD) was not affected. Body mass index (BMI) increased in all subjects but none was obese at the end of follow-up. Conclusions Treatment of patients with CPP with GnRH analogs every 3 months induces substantial increases in height and does not affect BMI or BMD. Therefore, it represents an attractive option for these young patients.Peripheral intravenous catheters are frequently used devices in emergency departments. Many patients now present with difficult anatomy and are labeled as difficult intravenous access patients. A common technology to address this challenge is ultrasound. While studies have examined the ability to train emergency staff, few have addressed how this should be done and the outcomes associated with such training. NCT-503 No studies were found with dedicated vascular access specialist teams in emergency departments. An emergency department vascular access specialist team was formed at a hospital in Bangor, Maine, United States to train, validate, and proctor clinicians with ultrasound-guided peripheral intravenous devices. A quality review of this process was compiled and determined that appropriate clinicians with dedicated training and guidance can achieve higher levels of procedural success. Furthermore, evidence substantiates that frequent practice is linked to a higher quality of care and that a significant need for such teams is present. This review examines how a team was implemented and its impact both department- and facility-wide. It is possible that hospitals benefit from the services of vascular access specialists to provide higher quality care. Successful implementation of such specialist teams requires foundational knowledge and skills in vascular access with ongoing quality measures to ensure competency and compliance with evidence-based practices.Difficulties with social communication and interaction are a hallmark feature of autism spectrum disorder. These difficulties may be the result of problems with explicit social cognition (effortful and largely conscious processes) such as learning and recalling social norms or rules. Alternatively, social deficits may stem from problems with implicit social cognition (rapid and largely unconscious processes) such as the efficient integration of social information. The goal of this study was to determine how problems in explicit and implicit social cognition relate to social behavior in 34 youth with autism spectrum disorder. We measured aspects of implicit and explicit social cognition abilities in the laboratory using behavioral, cognitive, and brain (electrophysiological) measures. We then used those measures to predict “real-world” social behavior as reported by parents, clinicians, and independent observers. Results showed that overall better aspects of implicit and explicit social cognition predicted more competent social behavior. In addition, the ability to fluidly integrate social information (implicit social cognition) was more frequently related to competent social behavior that merely knowing what to do in social situations (explicit social cognition). These findings may help with the development of interventions focusing on improving social deficits.
