SILICON-CONTROLLED RECTIFIER (SCR) DEVICE FOR HIGH-VOLTAGE ELECTROSTATIC DISCHARGE (ESD) APPLICATIONS

A silicon controlled rectifier (SCR) device having a high holding voltage includes a PNP transistor and an NPN transistor, each transistor having both p-type and n-type dopant regions in their respective emitter areas. The device is particularly suited to high voltage applications, as the high holding voltage provides a device which is more resistant to latchup subsequent to an electrostatic discharge event compared to devices having a low holding voltage

Hairy Leukoplakia

Oral hairy leukoplakia (OHL) is a disease of the mucosa first described in 1984. This pathology is associated with Epstein-Barr virus (EBV) and occurs mostly in people with HIV infection, both immunocompromised and immunocompetent, and can affect patients who are HIV negative. [1, 2] The first case in an HIV-negative patient was reported in 1999 in a 56-year-old patient with acute lymphocytic leukemia. Later, many cases were reported in heart, kidney, and bone marrow transplant recipients and patients with hematological malignancies. [3, 4

Hyperbaric pressure – laser assisted chemical vapor deposition of ceramic Si-based fibers

A method of growing ceramic fibers for CMC’s directly from the gas phase, called hyperbaric pressure laser-assisted chemical vapor deposition (HP-LCVD), has been investigated using SiC as a case study. In this process, a laser is focused onto a substrate whereupon the gas precursor decomposes under the focal point into its constituent species. Those species are deposited as a solid onto a substrate, nucleating a fiber which continues to grow parallel to the beam as the laser focus is withdrawn from the surface. This unique processing technique can be used to grow many fibers simultaneously using an array of beams as well as three-dimensional shapes by changing the orientation of the laser beam with respect to the tip. Depending on system pressure, laser energy, and tip retraction speed from the laser’s focus, a range of fiber diameters, surface morphologies, stable or meta-stable phases, and micro/nano-structures can be achieved. These features have been assembled into a process-structure map for SiC fabrication by this method. To gain further insights into the variables that drive the thermodynamics of nucleation and growth, an in situ two-color pyrometry technique has been employed to measure the temperature in the reaction zone during the fiber’s growth.

Acceptance of Behavior Guidance Techniques Used in Pediatric Dentistry by Parents From Diverse Backgrounds

Objective. To investigate if parental background affects acceptance of behavior guidance techniques. Background. Behavior guidance techniques are used for the safe and effective treatment of pediatric patients. Acceptance of these techniques may vary by racial and ethnic background. Methods. A total of 142 parents were recruited and asked to rate videos showing: active restraint/protective stabilization (AR), general anesthesia (GA), nitrous oxide sedation (N2O), oral premedication/sedation (OP), passive restraint/protective stabilization (PR), tell-show-do (TSD), and voice control (VC) techniques. Results. Hispanic parents rated VC most acceptable, followed by TSD, PR, and pharmacologic techniques. Black and white parents rated TSD, followed by N2O, as most acceptable, and AR and PR as least favorable. Hispanics found GA significantly less acceptable than whites or blacks. Hispanics were less accepting of AR than blacks; but more accepting of PR than whites. TSD was highly rated among all 3 cohorts. Parental background affected acceptance of the techniques in this study

Fluoride in the diet of 2-years-old children

Objectives This study aimed to calculate the fluoride concentrations of commonly consumed foods and beverages for 2-years-old children utilizing market basket information for the US Midwest region. Methods Total Diet Study food lists were cross-referenced with National Health and Nutrition Examination Survey—What We Eat in America data to determine the foods and beverages to be included. Fluoride concentrations were determined using a modification of the hexamethyldisiloxane microdiffusion technique. Fluoride concentrations were summarized for each of the food categories. Daily dietary fluoride intake was estimated using a simulation analysis. Results Food and beverage fluoride concentrations varied widely, ranging from nondetectable for some oils and dairy products to more than 3.0 μgF/g food for some processed meats, fish and fruits. The estimated mean (±SD) daily dietary fluoride intake, excluding dentifrice and supplements, was 412±114 μgF/d. The estimated average ingestion for a 2-years-old weighing 12.24 kg was 0.034±0.009 mg/kg/d. A diet based on foods and beverages in the fifth percentile of fluoride intake distribution for an average child would result in 247 μgF/d or 0.020 mg/kg/d, while a diet with foods and beverages in the 95th percentile would result in a total intake of 622 μgF/d or 0.051 mg/kg/d. Conclusions The fluoride concentrations of foods and beverages vary widely, and, if items in the 95th percentile of fluoride intake distribution are ingested, children could consume more fluoride than the recommended 0.05 mg/kg/d. Fluoride intake calculated in this study was higher than historically reported dietary levels

Significant Factors Related to Failed Pediatric Dental General Anesthesia Appointments at a Hospital-based Residency Program

Purpose: The purposes of this study were to: (1) evaluate the relationship between appointment failure and the factors of age, gender, race, insurance type, day of week, scheduled time of surgery, distance traveled, and weather; (2) investigate reasons for failure; and (3) explore the relationships between the factors and reasons for failure. Methods: Electronic medical records were accessed to obtain data for patients scheduled for dental care under general anesthesia from May 2012 to May 2015. Factors were analyzed for relation to appointment failure. Results: Data from 3,513 appointments for 2,874 children were analyzed. Bivariate associations showed statistically significant (P<0.05) relationships between failed appointment and race, insurance type, scheduled time of surgery, distance traveled, snowfall, and temperature. Multinomial regression analysis showed the following associations between factors and the reason for failure (P<0.05): (1) decreased temperature and increased snowfall were associated with weather as reason for failure; (2) the African American population showed an association with family barriers; (3) Hispanic families were less likely to give advanced notice; and (4) the "additional races" category showed an association with fasting violation. Conclusion: Patients who have treatment under general anesthesia face specific barriers to care

The effect of dynaCleft[R] on presurgical orthopedics in bilateral cleft lip and palate patients

Aims: The aim of this study was to determine the effects DynaCleft® has on patients with bilateral cleft lip and palate. Subjects and Methods: Comparative data were collected from a total of 46 infants diagnosed with bilateral cleft lip and palate between 1981 and 2017. Twenty-three infants were treated with DynaCleft® and an obturator and 23 infants received an obturator only. Maxillary impressions were taken at each infant's initial clinic visit and again on the day of his/her surgical cleft lip repair. Differences in maxillary retraction, sagittal repositioning, and cleft widths were compared between the two groups. Statistical Analysis Used: Paired t-tests were used to determine if there was significant change before and after DynaCleft® therapy, and two-sample t-tests were used to compare the data between the two study groups. Results: Clinically, DynaCleft® averaged more maxillary retraction and cleft size reduction on both the right and left sides compared to the control group. Within the DynaCleft® group, a statistically significant difference was found for premaxillary retraction on both the right and left sides. However, all the other comparisons between the two groups were not found to be statistically significant. Conclusions: DynaCleft® as a presurgical orthopedic therapy may help to limit uncontrolled physiological changes and reposition the premaxillary segment, while reducing cleft widths prior to definitive lip surgery

Benefit of continuous kidney replacement therapy for managing tumor lysis syndrome in children with hematologic malignancies

IntroductionTumor lysis syndrome (TLS) is often diagnosed in children with hematological malignancies and can be life threatening due to metabolic disturbances. Continuous renal replacement therapy (CKRT) can reverse these disturbances relatively quickly when conventional medical management fails. Our objective was to investigate the benefit of CKRT in the management of TLS in children admitted to the intensive care unit with hematologic malignancies. In addition, we sought to assess risk factors for acute kidney injury (AKI) in the setting of TLS.MethodsRetrospective review of all children admitted to the intensive care unit with TLS who received CKRT from January 2012 to August 2022.ResultsAmong 222 children hospitalized with TLS from January 2012 to August 2022, 20 (9%) underwent CKRT to manage TLS in the intensive care unit. The patients’ median age was 13 years (range 3-17 y), and most were males (18/20). T-cell acute lymphoblastic leukemia was the most common diagnosis (n=10), followed by acute myeloid leukemia (n=4), Burkitt lymphoma (n=4), and B-cell acute lymphoblastic leukemia (n=2). Five patients required mechanical ventilation, and 2 required vasopressors. The most common indication for CKRT was hyperphosphatemia, followed by, hyperuricemia, and hyperkalemia. All metabolic abnormalities corrected within 12 h of initiation of CKRT. CKRT courses were brief, with a median duration of 2 days (range 1-7 days). Having higher serum phosphorus levels 12 h preceding CKRT was significantly associated with severe acute kidney injury (AKI). The median phosphorus level was 6.4 mg/dL in children with no/mild AKI and 10.5 mg/dL in children with severe AKI (p=0.0375). Serum uric acid levels before CKRT were not associated with AKI. All children survived to hospital discharge, and the one-year survival rate was 90%.ConclusionCKRT is safe in children with hematologic malignancies with severe TLS and reverses metabolic derangements within 6-12 h. Most patients had AKI at the initiation of CKRT but did not require long-term kidney replacement therapy. Hyperphosphatemia before initiation of CKRT is associated with higher risk of AKI
