The Irish Rover: Phil Lynott and the Search for Identity

Phil Lynott, the lead singer of the rock band Thin Lizzy, was a complex character. An illegitimate black child who grew up in a working-class, Catholic district of Dublin, Ireland in the 1950s, Lynott spent his life searching for a sense of belonging, something which he explored through rock and roll. This study uses Lynott’s song lyrics to investigate his quest for identity. In particular, it identifies the many recurring themes and archetypes in his music that offered multifaceted self-portraits of his internal conflict between being black, Irish, illegitimate, a rockstar, a Lothario, a son, a father, and a husband, all at the same time

Global Retinoblastoma Presentation and Analysis by National Income Level

Importance: Early diagnosis of retinoblastoma, the most common intraocular cancer, can save both a child's life and vision. However, anecdotal evidence suggests that many children across the world are diagnosed late. To our knowledge, the clinical presentation of retinoblastoma has never been assessed on a global scale. Objectives: To report the retinoblastoma stage at diagnosis in patients across the world during a single year, to investigate associations between clinical variables and national income level, and to investigate risk factors for advanced disease at diagnosis. Design, Setting, and Participants: A total of 278 retinoblastoma treatment centers were recruited from June 2017 through December 2018 to participate in a cross-sectional analysis of treatment-naive patients with retinoblastoma who were diagnosed in 2017. Main Outcomes and Measures: Age at presentation, proportion of familial history of retinoblastoma, and tumor stage and metastasis. Results: The cohort included 4351 new patients from 153 countries; the median age at diagnosis was 30.5 (interquartile range, 18.3-45.9) months, and 1976 patients (45.4) were female. Most patients (n = 3685 84.7%) were from low-and middle-income countries (LMICs). Globally, the most common indication for referral was leukocoria (n = 2638 62.8%), followed by strabismus (n = 429 10.2%) and proptosis (n = 309 7.4%). Patients from high-income countries (HICs) were diagnosed at a median age of 14.1 months, with 656 of 666 (98.5%) patients having intraocular retinoblastoma and 2 (0.3%) having metastasis. Patients from low-income countries were diagnosed at a median age of 30.5 months, with 256 of 521 (49.1%) having extraocular retinoblastoma and 94 of 498 (18.9%) having metastasis. Lower national income level was associated with older presentation age, higher proportion of locally advanced disease and distant metastasis, and smaller proportion of familial history of retinoblastoma. Advanced disease at diagnosis was more common in LMICs even after adjusting for age (odds ratio for low-income countries vs upper-middle-income countries and HICs, 17.92 95% CI, 12.94-24.80, and for lower-middle-income countries vs upper-middle-income countries and HICs, 5.74 95% CI, 4.30-7.68). Conclusions and Relevance: This study is estimated to have included more than half of all new retinoblastoma cases worldwide in 2017. Children from LMICs, where the main global retinoblastoma burden lies, presented at an older age with more advanced disease and demonstrated a smaller proportion of familial history of retinoblastoma, likely because many do not reach a childbearing age. Given that retinoblastoma is curable, these data are concerning and mandate intervention at national and international levels. Further studies are needed to investigate factors, other than age at presentation, that may be associated with advanced disease in LMICs. © 2020 American Medical Association. All rights reserved

Mucosal Repair of Posterior Perforation of Duodenal Diverticulitis Using Roux Loop Duodenojejunostomy

Perforation of duodenal diverticulum is a rare occurrence but has a potentially fatal outcome. It is a difficult surgical problem because of delayed diagnosis and the attendant risk of duodenal fistula following primary repair. We present a case of posterior perforation of duodenal diverticulitis, diagnosed on computed tomography and successfully repaired with a Roux loop duodenojejunostomy. We also discuss the rare pathology, diagnosis and surgical options with special reference to this alternative form of mucosal repair

Movement Disorders in Patients with Genetic Developmental and Epileptic Encephalopathies

Background and Objectives: Movement disorders (MDs) are underrecognized in the developmental and epileptic encephalopathies (DEEs). There are now more than 800 genes implicated in causing the DEEs; relatively few of these rare genetic diseases are known to be associated with MDs. We identified patients with genetic DEEs who had MDs, classified the nature of their MDs, and asked whether specific patterns correlated with the underlying mechanism.Methods: We classified the type of MDs associated with specific genetic DEEs in a large international cohort of patients and analyzed whether specific patterns of MDs reflected the underlying biological dysfunction.Results: Our cohort comprised 77 patients with a genetic DEE with a median age of 9 (range 1-38) years. Stereotypies (37/77, 48%) and dystonia (34/77, 44%) were the most frequent MDs, followed by chorea (18/77, 23%), myoclonus (14/77, 18%), ataxia (9/77, 12%), tremor (7/77, 9%), and hypokinesia (6/77, 8%). In 47% of patients, a combination of MDs was seen. The MDs were first observed at a median age of 18 months (range day 2-35 years). Dystonia was more likely to be observed in nonambulatory patients, while ataxia was less likely. In 46% of patients, therapy was initiated with medication (34/77, 44%), deep brain stimulation (1/77, 1%), or intrathecal baclofen (1/77, 1%). We found that patients with channelopathies or synaptic vesicle trafficking defects were more likely to experience dystonia; whereas, stereotypies were most frequent in individuals with transcriptional defects.Discussion: MDs are often underrecognized in patients with genetic DEEs, but recognition is critical for the management of these complex neurologic diseases. Distinguishing MDs from epileptic seizures is important in tailoring patient treatment. Understanding which MDs occur with different biological mechanisms will inform early diagnosis and management.</p

Seminal vesicle inter- and intra-fraction motion during radiotherapy for prostate cancer: A review

A review of studies on seminal vesicle motion was performed to improve the understanding of these treatment uncertainties. This will aid planning target volume margin reduction, which is necessary for hypofractionation of high-risk prostate cancer. Embase, Medline, Web of science Core collection, Cochrane CENTRAL register of trials and Google scholar were searched for publications including 3D information on seminal vesicle motion. In total 646 publications were found of which 22 publications were eligible for inclusion. The mean, systematic and random error of inter- and intra-fraction translations are reported, as well as rotations. The translations of the seminal vesicles is smallest in the left–right direction, whereas the rotation was largest around this axis. Although rectal and bladder filling status were the main cause for seminal vesicle motion, no apparent effect on magnitude of motion was seen when different bladder and rectal preparation protocols were used. Inter- and intra-fraction motion of the seminal vesicles is significant. In the studies, systematic and random errors range between 1–7 mm and 1–5 mm respectively, and are largely uncorrelated to prostate motion. The maximum correlation between seminal vesicle and prostate motion was reported with an R2 of 0.7, while 3 other studies report lower and/or non-significant correlations. Five studies report a planning target volume margin of approximately 8 mm. This margin is in line with the results of four relevant dosimetric studies. Mitigating the inter- and intra-fraction motion of the seminal vesicles, including prostate tracking, has the potential to reduce planning target volume margins
