Published: June 2020

Abstract
Context: Adrenal tumors can arise either from cortex or from medulla; both the regions being structurally and functionally different. Current knowledge on childhood adrenocortical tumors (ACTs), the management approach, and the outcome is limited due to limited number of cases and studies. Neuroblastoma is a neoplasm of the neural crest origin and 50% arise from adrenal medulla. Pheochromocytoma (PCC) is an exciting and rare neoplasm in childhood. Aims: To evaluate the clinical presentation, spectrum of pathology, and management of adrenal tumors in children. Subjects and Methods: The study was conducted in a tertiary care pediatric institute over 5 years on children with intra-abdominal solid tumors. Adrenal tumors were diagnosed on radiological studies and postoperatively confirmed by histopathology. Results: Sixty-three patients were operated for intra-abdominal solid tumors, and Wilms tumor (39) was the most common finding. Of 11 cases of adrenal tumors confirmed by histopathology, eight were adrenal neuroblastoma, one 14-month-old female baby was detected as PCC, while two female children presented with the features of Cushing syndrome and virilization at the age of 3 and 7 years. Postoperatively, one of them was found to be adrenal adenoma and one was found to be adrenocortical carcinoma. Conclusions: ACTs are rare and potentially fatal in childhood. Complete surgical resection is the mainstay of therapy in adrenal tumors and is curative for associated hypertension. Neuroblastoma was the third common intra-abdominal solid tumor after Wilms tumor and retroperitoneal teratoma. The patient with PCC contributed to “Rule of 10s” because of the absence of hypertension and childhood occurrence.

Published: June 2020

AbstractPapillary tumor of the pineal region (PTPR) is a rare neuroepithelial tumor first described in 2003. It is a newly recognized entity and introduced in the WHO classification of central nervous system tumors in 2007. Till date, about 70 cases have been described in literature. Herein, we report an additional case of PTPR in a 25-year-old male with emphasis on immunohistochemistry and ultrastructural features. Interestingly, this case showed a unique membranous as well as dot-like Golgi zone keratin (AE1/AE3 and CK18) expression pattern.

Published: June 2020

AbstractPleuroparenchymal fibroelastosis (PPFE) is a rare progressive interstitial lung disease presenting with predominantly upper-lobe pleural thickening and pulmonary fibrosis. While most cases are idiopathic, it is rarely seen as a complication of infection or following chemotherapy, radiation therapy, and bone marrow transplant. We describe a case of early onset and rapidly progressive PPFE as a complication of cyclophosphamide chemotherapy.

Authors: Sakthisankari S , Kumar Prasanna N , Syed Tabbu 
Published: June 2020

AbstractAnaplastic multiple myeloma (AMM) is a rare and aggressive variant of plasma cell neoplasm. It is relatively treatment resistant when compared to conventional myeloma. It can arise de novo or transform from a preexisting plasma cell myeloma. Morphologically, AMM is recognized by the presence of immature plasma cells and pleomorphic, multilobated cells. Here, we present three cases of AMM.

Objectives:
The objective of this study is to determine the subclinical vestibular dysfunction of patients with vestibular migraine (VM) in the interattack period who had no vestibular symptoms. We assessed ascending utricular and descending saccular pathways using cervical vestibular-evoked myogenic potentials (cVEMP) and ocular vestibular-evoked myogenic potentials (oVEMP) in patients with VM and a healthy control group and then compared the electrophysiologic findings with each other.

Materials and Methods:
Between January 2017 and January 2018, 116 patients (aged 18–62 years) were enrolled in the study. The study group consisted of 68 women with VM and the control group comprised 48 healthy women.

Results:
For cVEMP findings, the mean left ear P1 latency of the VM group was statistically significantly longer than that of the control group (P = 0.024; P < 0.05). No statistical significance was found in left ear N1 latency, P1-N1 interpeak intervals and mean amplitudes between the VM and the control groups (P > 0.05). Amplitude asymmetry ratios (AARs) were not statistically significantly different between the two groups in cVEMP (P > 0.05). In terms of oVEMP findings, no statistically significant difference was found in the right ear parameters of N1, P1, P1-N1 intervals, and amplitudes of the VM and the control groups (P > 0.05). The left ear oVEMPs of the VM group showed absent responses in 12 cases and were statistically significant compared with the control group (P = 0.037; P < 0.05). The AARs were significantly greater for the the VM group than the control group in oVEMP (P = 0.006; P < 0.05).

Conclusion:
These electrophysiologic findings suggest that peripheral vestibular structures such as the utricle, saccule and also other central vestibular structures might be affected in VM. Patients with VM had subclinical vestibular dysfunction despite being in the interattack period. To support the diagnosis of VM, VEMPs are easy and cost-effective tests.
Ring-theoretic (In)finiteness in reduced products of Banach algebras
Authors: Daws Matthew , Horváth Bence 
Published: June 2020

AbstractWe study ring-theoretic (in)finiteness properties—such as Dedekind-finiteness and proper infiniteness—of ultraproducts (and more generally, reduced products) of Banach algebras.While we characterise when an ultraproduct has these ring-theoretic properties in terms of its underlying sequence of algebras, we find that, contrary to the
$C^*$
-algebraic setting, it is not true in general that an ultraproduct has a ring-theoretic finiteness property if and only if “ultrafilter many” of the underlying sequence of algebras have the same property. This might appear to violate the continuous model theoretic counterpart of Łoś’s Theorem; the reason it does not is that for a general Banach algebra, the ring theoretic properties we consider cannot be verified by considering a bounded subset of the algebra of fixed bound. For Banach algebras, we construct counter-examples to show, for example, that each component Banach algebra can fail to be Dedekind-finite while the ultraproduct is Dedekind-finite, and we explain why such a counter-example is not possible for
$C^*$
-algebras. Finally, the related notion of having stable rank one is also studied for ultraproducts.
Deligne–Lusztig varieties and basic EKOR strata
Authors: Wang Haining 
Published: June 2020

AbstractUsing the axioms of He and Rapoport for the stratifications of Shimura varieties, we explain a result of Görtz, He, and Nie that the EKOR strata contained in the basic loci can be described as a disjoint union of Deligne–Lusztig varieties. In the special case of Siegel modular varieties, we compare their descriptions to that of Görtz and Yu for the supersingular Kottwitz-Rapoport strata and to the descriptions of Harashita and Hoeve for the supersingular Ekedahl–Oort strata.

Background: Intellectual disability (ID) is a neuro-developmental defect that is manifested by development delay and learning disability. Such defects may be caused due to chromosomal disorders (trisomy 18 or Down syndrome) or single gene mutation. Its worldwide prevalence is estimated to be 1-3%. The genetic etiology of non-syndromic ID is poorly understood. To date, more than 100 loci have been reported to be associated with non-syndromic ID. The objective of this study was to identify the causative genes for three Materials & Methods: This cross-sectional study was conducted in the Institute of Basic Medical Sciences, Khyber Medical University, Peshawar, Pakistan from March 2014 to August 2015. The inclusion criteria set for the families was consanguineous relation and more than two patients per family (including cousins). All the patients were tested individually in friendly atmosphere using IQ test to scale the ID on the basis of performance. Thereafter, blood samples were taken by aseptic method and DNA was extracted for the purpose of doing genetic analysis. In genetic analysis, exome sequencing was performed to find the pathogenic variants. Subsequently. Sanger sequencing was also done to see the segregation of pathogenic variants.
Results: Genetic analysis found mutation in AP4B1 in Family 1, in WDR62 in Family 2, while Family 3 was unremarkable.
Conclusion: The study involved genetic analysis of three consanguineous families and found mutation in AP4B1 in Family 1, in WDR62 in Family 2, while Family 3 was unremarkable. The present research will help in devising molecular diagnostic technics for pre-marital and pre-conception testing.

Authors: Cortez Azenón Manuel , Ayala Durán Carlos 
Published: June 2020

Se evidencia que existe en El Salvador estudios sobre fitomejoramiento de maíz que priorizan usualmente la investigación de maíces híbridos, dejando de lado variedades de polinización libre y criollas. Asimismo, numerosas investigaciones suelen centrarse generalmente en aspectos productivos de este cereal. Ante esta tendencia, el presente texto realiza un análisis de aspectos nutricionales de maíces criollos salvadoreños. Para ello, se realiza un análisis bromatológico mediante el método de fluorescencia de rayos X, identificando el porcentaje de proteína, el contenido de hierro y de zinc en seis maíces criollos salvadoreños y un testigo híbrido comercial. Los resultados muestran que los maíces criollos presentan en términos generales índices nutricionales similares y en algunos casos superiores al híbrido. Con ello, el testigo comercial no registra un desempeño superior en ninguno de los tres nutrientes evaluados, mostrando el peor índice en contenido de hierro y el penúltimo peor en contenido de zinc y porcentaje de proteína.
Estimating Mass Concentration Using a Low-cost Portable Particle Counter Based on Full-year Observations: Issues to Obtain Reliable Atmospheric PM2.5 Data

Published: June 2020

Abstract
Expanding the use of a recently introduced low-cost particle monitor (DC1700 Dylos Air Quality Monitor) for sensing atmospheric PM2.5 requires comparison with data obtained using a certified method for PM2.5 based on appropriate atmospheric observations. Full-year measurements of atmospheric aerosols were taken in Nagoya, Japan during March 2017-March 2018 using the DC1700 to measure the particle number concentrations of >0.5 and >2.5 μm diameter particles and to measure the PM2.5 mass concentration (M
dry, PM2.5) using an automated β attenuation mass monitor (PM712). The number-size distribution was measured using an optical particle counter (KC01D). The dried mass concentration of 0.5–2.5 μm particles (M
dry, 0.5–2.5) was estimated from the ambient relative humidity and the DC1700 number concentration. The values of M
dry, 0.5–2.5 were invariably less than those of M
dry, PM2.5. The coefficient of determination and slope of M
dry, 0.5–2.5 to M
dry, PM2.5 for the year were, respectively, 0.68 and 0.40. Slope values changed seasonally from 0.24 in July and August 2017 to 0.55 in May and April 2017. Light absorbing particles, smaller-fine particles, and the estimation method of M
dry, 0.5–2.5 were inferred as causes of the difference between M
dry, 0.5–2.5 and M
dry, PM2.5. Especially, we estimated a large contribution (ca. 54% underestimation of M
dry, 0.5–2.5 into M
dry, PM2.5) of particles smaller than the minimum detection diameter of DC1700. The seasonal variation of M
dry, 0.5–2.5/M
dry, PM2.5 was related to the volume fraction of particles smaller than 0.5 μm. Good correlation of M
dry, 0.5–2.5 to M
dry, PM2.5 suggests that data obtained using DC1700 with a correction factor are useful as a rough proxy of atmospheric PM2.5 within a season. However, precise estimation of PM2.5 from the DC1700 number concentrations should include appropriate corrections of the size distribution, not only hygroscopicity.
Gemein und ungleich

Die erste Gesellschaftsgeschichte der Essener Mark bei Osnabrück von der Reformation bis in den Vormärz.

Für die Geschichte der ländlichen Gesellschaft Nordwestdeutschlands spielten die gemeinen Marken über Jahrhunderte hinweg eine prägende Rolle. Dabei handelte es sich um ländliche Gemeingüter, in denen die Aneignung natürlicher Ressourcen von sozialen Kollektiven organisiert wurde. In den Osnabrücker Marken wirkten Akteure aus Landesherrschaft, Grundherrschaft und Bauernschaft an der gemeinschaftlichen Verwaltung und Nutzung von Wald, Weide und Heide mit. Die Fallstudie zur Essener Mark untersucht anhand archivalischer Quellen den kollektiven Umgang dieser ungleichen Akteure mit land- und waldwirtschaftlichen Ressourcen.
Jonas Hübner liefert damit erstmals eine Gesamtdarstellung ländlicher Gemeingüterverwaltung und -nutzung in einem frühneuzeitlichen Markenverband vom späten 16. bis ins frühe 19. Jahrhundert. Gegenstand der Analyse sind die Kooperationen und Konflikte im Spannungsfeld von Landesherrschaft, Gutsherren und bäuerlicher Selbstverwaltung. Dabei geht es auch um die Positionierung der ständischen Akteure im Prozess der Agrarreformen, die schließlich zur Auflösung der gemeinen Marken führten.
Amos y putos amos: nuevos lenguajes escénicos para nuevos Lazarillos

Published: June 2020

Con su particular Lázaro (Leam?k, 2019), Roberto Hoyo saca a escena el clásico narrativo del XVI como un pequeño canto en clave metadramática al oficio del teatro. Impulsora de un diálogo con las problemáticas sociales enraizadas en la generación Z, la obra constituye un camino de indagación hacia otros lenguajes. Las convenciones tradicionales abren paso a una inquietud por el ritmo que encuentra su cauce en la cultura hip hop, donde música y verso ofrecen nuevos vínculos con el patrimonio vivo de los Siglos de Oro.
Sister Mary Joseph Nodule in a Patient With Advanced Prostate Cancer
Authors: Chahin Michael , Kogler William , Stack Anthony , Lyons Brittany 
Published: June 2020

Abstract
Prostate cancer is the second most common cause of cancer death among US men. Metastasis typically occurs in the bone, lymph nodes, liver, and thorax. This case highlights a patient who was suspected of having prostate cancer several years before presenting to the emergency department with back pain and an umbilical hernia of increasing size. Gross examination revealed fixed masses on the abdominal wall that appeared malignant on computed tomographic imaging. The umbilical mass was a Sister Mary Joseph nodule (SMJN), which is sometimes found in patients with advanced, metastatic abdominal cancer. An SMJN is most commonly suggestive of gastrointestinal or gynecologic cancer, but it is a rarely reported finding in the context of prostate cancer. SMJN is a frequently missed finding that may delay further investigation for malignant neoplasms. This case reinforces the importance of this physical examination finding and provides evidence for adding prostate cancer to the list of possible diagnoses for patients who have an SMJN.
