st both for target coverage and OARs sparing. Standard IMRT plans were less robust than proton plans in regards to high doses to neurological OARs. However, robust optimization applied to IMRT resulted in improved robustness in both target coverage and high doses to OARs. Robustness evaluation may be considered as a part of plan evaluation procedure even in IMRT. Based on the five cases presented in the current study, all proton planning techniques (SFO, MFO and HB-MFO) were robust both for target coverage and OARs sparing. Standard IMRT plans were less robust than proton plans in regards to high doses to neurological OARs. However, robust optimization applied to IMRT resulted in improved robustness in both target coverage and high doses to OARs. Robustness evaluation may be considered as a part of plan evaluation procedure even in IMRT. This study aims to derive simple yet robust formula(s) for the calculation of cranial tumor volume using linear tumor dimensions in anterioposterior (AP), mediolateral (ML) and craniocaudal (CC) directions and also propose a reproducible methodology for tumor dimension measurements. Magnetic resonance images (MRI) of 337 patients planned for Gammaknife Stereotactic Radiosurgery for different types of brain tumors were analyzed using Leksell Gamma Plan (LGP) software. Tumor volume in three dimensional was outlined and maximum tumor diameters were measured in three orthogonal directions AP, ML, and CC on the MRI. Formulas were derived to calculate tumor volume from AP, ML, and CC diameters using linear regression technique. An agreement between the calculated volume and standard volume observed from LGP software was determined using Bland Altman (B-A) plot. A comparison was made between the volume calculated using traditionally used formula of ellipsoid, standard volume obtained from LGP software and volumeimple and reproducible.The Family Stress Model (FSM) is an influential family process model that posits that socioeconomic disadvantage impacts child outcomes via its effects on parents. Existing evaluations of the FSM are constrained by limited measures of socioeconomic disadvantage, cross-sectional research designs, and reliance on non-population-based samples. The current study tested the FSM in a subsample of the Fragile Families and Child Wellbeing Study (N = 2,918), a large population-based study of children followed from birth through age 9. We employed a longitudinal framework and used measures of socioeconomic disadvantage beyond economic resources. Although the hypothesized FSM pathways were identified in the longitudinal model (e.g., economic pressure at age 1 was associated with maternal distress at age 3, maternal distress at age 3 was associated with parenting behaviors at age 5), the effects of socioeconomic disadvantage at childbirth on youth socioemotional outcomes at age 9 did not operate through all of the hypothesized mediators. In longitudinal change models that accounted for the stability in constructs, multiple indicators of socioeconomic disadvantage at childbirth were indirectly associated with youth externalizing behaviors at age 9 via either economic pressure at age 1 or changes in maternal warmth from ages 3 to 5. Greater economic pressure at age 1, increases in maternal distress from ages 1 to 3, and decreases/increases in maternal warmth/harshness from ages 3 to 5 were also directly associated with increases in externalizing behaviors from ages 5 to 9. Results provide partial support for the FSM across the first decade of life.How do we define the beginnings of human life? Images, science, and culture have offered insight into this question. The early modern period (1500-1800) is particularly rich for examining the understanding of the human fetus. Using the 1712 Essay on the Possibility and Probability of a Child's Being Born Alive, and Live, in the Latter End of the Fifth Solar, or in the Beginning of the Sixth Lunar Month, this paper argues that evolving knowledge of the fetus failed to modify cultural norms for defining the beginning of human life. https://www.selleckchem.com/products/ru-521.html This compares with contemporary 21st century observations and how our definition of the beginning of human life has not been modified.External cephalic version (ECV) has been successfully utilized to reduce breech presentations at term and offers an alternative to elective cesarean delivery. Unfortunately, there is not a consensus on which type of regional anesthesia conveys the highest chances for a successful ECV. This case report describes the use of the epidural volume extension technique to provide surgical anesthesia for ECV with a reduced dose of local anesthetic, with the goals of minimizing motor block and hypotension in the setting of an outpatient procedure.Achondroplasia is a genetic condition caused by disordered endochondral ossification, which leads to rhizomelic dwarfism and midfacial hypoplasia. Additionally, several morphologic changes in the temporal bone are thought to at least partially contribute to hearing loss in these patients. We present a patient with achondroplasia who presented with hearing loss and was referred to radiology for temporal bone imaging. High-resolution computed tomography of temporal bones demonstrated several interesting morphological abnormalities characteristic of achondroplasia.Penile calciphylaxis is a rare cause of penile gangrene and is typically associated with multiple comorbidities, most commonly diabetes mellitus and hyperparathyroidism. It demonstrates a high mortality rate of 64% and is seen almost exclusively in patients with end-stage renal disease on hemodialysis. Underreporting of this disease likely occurs, contributing to a paucity of data and lack of formal therapeutic guidelines and approved treatments. Conflicting guidance exists regarding effective treatment strategies, with most formal literature existing in the form of case reports. Herein, we describe a 44-year-old man with end-stage renal disease on hemodialysis who presented with a 2-month history of nonhealing wounds on his penis and lower extremities.Thermal burn injuries are a known complication of forced-air warming devices but rarely occur when the device is used in accordance with the manufacturer's instructions. Here we present a case of a 3-year-old girl who in the immediate postoperative period was found to have prominent linear, evenly spaced vesicles and bullae in a pattern that distinctly matched the air-exit perforations of the Bair Hugger device. Clinicians should be aware of potential complications arising from even proper use of a medical device and take all necessary precautions to prevent such incidents.
