recommended location was high. Left-sided catheters, patient weight, and sex were associated with malposition. Malpositioned catheters were not associated with increased harm.

During the 2013 to 2016 outbreak in the Pacific and Americas, Zika virus infection resulted not only in febrile and cutaneous manifestations but also in (severe) neurologic complications. These included both central and peripheral nervous system disorders. The most frequent was Guillain-Barré syndrome that typically developed 1 to 2 weeks after the acute infection. Later, other peripheral nervous system syndromes were recognized in association with the viral infection, broadening the spectrum of Zika virus-related peripheral nervous system syndromes. In the current article, the authors review all available clinical neurophysiology data on Guillain-Barré syndrome and other peripheral nervous system syndromes in an attempt to characterize the major patterns of involvement related to Zika virus. The authors also highlight the clinical usefulness of nerve conduction studies and needle EMG in the investigation of suspected Zika virus-related Guillain-Barré syndrome.

The congenital Zika syndrome is a new entity of a group of etiologies that can lead to microcephaly and other brain damages during pregnancy, such as toxoplasmosis, rubeola, cytomegalovirus, and herpes simplex. The Zika virus crosses the placental barrier and, predominantly, affects neuronal progenitor cells. selleck chemical This disruptive process results in severe cortical developmental disorder, calcifications, cortical and subcortical atrophies, and malformations of the cerebellum, brain stem, and spinal cord. Children with congenital Zika syndrome have a set of clinical findings, such as cerebral palsy, dysphagia, orthopedic deformities, visual and auditory impairment, and, rarely, hydrocephalus. Because of the severity of brain lesions, epilepsy is a common finding and a frequent cause of increased morbidity. The prevalence of epilepsy in different series of patients ranges from 37.7% to 71.4%. The aim of this study is to review the studies published so far regarding epilepsy and the EEG pattern in series of patients pattern in series of patients with congenital Zika syndrome.

Zika virus (ZIKV) has been shown to be highly neurotropic; neurologic disorders are a common complication of this infection. Encephalitis-an inflammation of the brain parenchyma associated with neurologic dysfunction-is a rare complication of ZIKV infections. It affects patients from young to elderly ages. Clinical presentation of ZIKV encephalitis may be heterogeneous, including altered mental status (decreased or altered level of consciousness, lethargy, or personality change), seizures, and focal deficits. Complementary diagnostic investigation should include neuroimaging, lumbar puncture, and EEG. Neuroimaging findings in ZIKV encephalitis are not specific and may be diverse, including normal findings, hyperintense lesions on MRI involving cortical or subcortical structures, symmetric or asymmetric lesions involving supra or infratentorial regions, and more widespread involvement such as brain swelling. A remarkable scarcity of neurophysiological data on ZIKV encephalitis was found in the literature.

A remarkable scarcity of neurophysiological data on ZIKV encephalitis was found in the literature. In line with other diagnostic examinations, there are no neurophysiological findings suggestive or specific of the disease. EEG in ZIKV encephalitis showed different results normal or diffuse disorganization of background activity, asymmetry with abnormal focal slow waves, focal epileptic discharges or generalized spike-wave and multispike-wave complexes, and periods of generalized voltage attenuation.Over the past decades, the treatment of ST-segment elevation myocardial infarction (STEMI) has been redefined with the incorporation of evidence from multiple clinical trials. Recommendations from guidelines are updated regularly to reduce morbidity and mortality. However, heterogeneous care systems, physician perspectives, and patient behavior still lead to a disparity between evidence and clinical practice. The quality of care has been established and become an integral part of modern healthcare in order to increase the likelihood of desired health outcomes and adhere to professional knowledge. For patients with STEMI, measuring the quality of care is a multifactorial and multidimensional process that cannot be estimated solely based on patients' clinical outcomes. The care of STEMI is similar to the concept of "the chain of survival" that emphasizes the importance of seamless integration of five links early recognition and diagnosis, timely reperfusion, evidence-based medications, control of cholesterol, and cardiac rehabilitation. Serial quality indicators, reflecting the full spectrum of care, have become a widely used tool for assessing performance. Comprehension of every aspect of quality assessment and indicators might be too demanding for a physician. However, it is worthwhile to understand the concepts involved in quality improvement since every physician wants to provide better care for their patients. This article reviews a fundamental approach to quality care in STEMI.

Understanding how medical scribes impact care delivery can inform decision-makers who must balance the cost of hiring scribes with their contribution to alleviating clinician burden.

The objective of this study was to understand how scribes impacted provider efficiency and satisfaction.

This was mixed-methods study.

Internal and family medicine clinicians were included.

We administered structured surveys and conducted unstructured interviews with clinicians who adopted scribes. We collected average days to close charts and quantity of after-hours clinical work in the 6 months before and after implementation using electronic health record data. We conducted a difference in difference (DID) analysis using a multilevel Poisson regression.

Three themes emerged from the interviews (1) charting time is less after training; (2) clinicians wanted to continue working with scribes; and (3) scribes did not reduce the overall inbox burden. In the 6-month survey, 76% of clinicians endorsed that working with a scribe improved work satisfaction versus 50% at 1 month. After implementation, days to chart closure decreased [DID=0.38 fewer days; 95% confidence interval (CI) -0.61, -0.15] the average minutes worked after hours on clinic days decreased (DID=-11.5 min/d; 95% CI -13.1, -9.9) as did minutes worked on nonclinical days (DID=-24.9 min/d; 95% CI -28.1, -21.7).

Working with scribes was associated with reduced time to close charts and reduced time using the electronic health record, markers of efficiency. Increased satisfaction accrued once scribes had experience.

The purpose of this study was to explore the surgical treatment of intraspinal rib head dislocation (IRH) in children with dystrophic scoliosis secondary to type 1 neurofibromatosis (NF1-DS).

From 2006 to 2019, 32 of 128 patients with NF1-DS were found to have IRH and enrolled in this study. There were 19 boys and 13 girls with an average age of 8.8±2.6 years. Patients were divided into 2 groups group A (n=25) without IRH resection and group B (n=7) with IRH resection. The intraspinal rib proportion (IRP), apical vertebra rotation, apical vertebral translation, main thoracic curve Cobb angle, trunk shift and thoracic kyphosis, lumbar lordosis, and sagittal vertebral axis were measured before and after the operation. Spinal injury was graded based on the American Spinal Injury Association (ASIA) Impairment Scale.

The study group had a total of 42 IRH. The mean follow-up duration was 46.1±28.7 months. The preoperative IRP in both groups was similar (35.5±14.3% vs. 31.2±15.3%, P=0.522). The postoperative IRP was lower in group B (18.5±11.2% vs. 0%, P=0.002). The IRP in group A decreased from preoperative (31.2±15.3%) to postoperative (18.5±11.2%) (P<0.05). There was no significant difference in the apical vertebra rotation, apical vertebral translation, main thoracic curve Cobb angle, trunk shift, thoracic kyphosis, lumbar lordosis, and sagittal vertebral axis between the 2 groups before surgery and after surgery. Four patients with nerve injury caused by the IRH had full neurological recovery postoperatively. All patients were ASIA grade E at the last follow-up.

The surgical treatment of IRH in children with NF1-DS should be determined on the basis of the presence of preoperative neurological symptoms. This study supports the practice of correcting spinal deformities only in patients with mild or no spinal cord injury. If there are obvious neurological symptoms, IRH resection is necessary to relieve spinal cord compression to recover nerve function.

Thread delamination associated with cannulated screws have been reported but likely represent an under-recognized complication in the orthopaedic literature. The purpose of this study is to report the occurrence of repeated hardware failures through thread delamination in the setting of a commonly used orthopaedic cannulated screw implant in a small cohort involving pediatric fracture care at a single academic level I trauma center.

Between August 2015 and December 2020, 9 cases of hardware failure associated with 4.5 mm arbeitsgemeinschaft für osteosynthesefragen cannulated stainless-steel screws were identified within a pediatric orthopaedic division at a single academic level I trauma center. Three cases were excluded, and 6 cases of thread delamination were retrospectively reviewed.

Six cases of thread delamination comprised a cohort of patients with a mean age of 13.7 years (range 12 to 15 y). All cases involved 4.5 mm arbeitsgemeinschaft für osteosynthesefragen cannulated screws, including 5 partially threaded and 1 fully threaded screw.
