Paraneoplastic Autoimmunity Associated with Testicular Myeloid Sarcoma and Chronic Myelomonocytic Leukemia by Jeffrey W. Craig, Richard J. Lin

“…The clinical presentations of these malignant neoplasms are highly variable, ranging from asymptomatic to localized mass effect. Here, we report an unusual case of myeloid sarcoma of the testis found in association with chronic myelomonocytic leukemia where the presenting symptoms were autoimmune pericarditis and migratory arthralgias and myalgias that preceded testicular enlargement by nearly three months. …”

Hawking-Unruh Hadronization and Strangeness Production in High Energy Collisions by Paolo Castorina, Helmut Satz

“…In nucleus-nucleus collisions, where the quark density is much bigger, one has to introduce an average temperature (acceleration) which dilutes the quark mass effect and the strangeness suppression almost disappears.…”

Fast Transient Thermal Analysis of Non-Fourier Heat Conduction Using Tikhonov Well-Conditioned Asymptotic Waveform Evaluation by Sohel Rana, Jeevan Kanesan, Ahmed Wasif Reza, Harikrishnan Ramiah

“…To reduce the increased computational time by Tikhonov WCAWE using ML (TWCAWE-ML), another well-conditioned scheme, called mass effect (ME) T-WCAWE, is introduced. TWCAWE with ME (TWCAWE-ME) showed more stable and accurate temperature spectrum in comparison to asymptotic wave evaluation (AWE) and also partial Pade AWE without sacrificing the computational time. …”

Spontaneous Involution of a Presumably Rathke’s Cleft Cyst in a Patient with Slight Subclinical Hypopituitarism: A Case Report and Review of the Literature by Diaa Al Safatli, Rolf Kalff, Albrecht Waschke

“…However, spontaneous regression is possible and justifies the conservative therapy with regular clinical and radiological follow-up for asymptomatic patients or patients with symptoms not caused by the mass effect of these lesions.…”

Bleeding versus Clotting: A Complex Case of a Large Fibroid Uterus Causing Menorrhagia and a DVT by Sangeeta Ramanan, Jude Chapman-Wardy, Roy Watson

“…After initial stabilization with multiple blood transfusions and reversal of anticoagulation, the warfarin was ceased in favour of enoxaparin and she underwent inferior vena cava (IVC) filter insertion prior to a total abdominal hysterectomy. Mass effect from large uterine fibroids can cause venous thromboembolism (VTE). …”

Intracranial Gliofibroma: A Case Report and Review of the Literature by Patricia Gargano, Graciela Zuccaro, Fabiana Lubieniecki

“…Neuroimaging showed a hemispheric hyperdense tumor with little peritumoral edema and no mass effect. The tumor was totally removed. Histologically, the tumor consisted of a mixture of glial cells and collagen-rich stroma. …”

An Unusual Initial Presentation of Lupus Nephritis as a Renal Mass by Remi Goupil, Annie-Claire Nadeau-Fredette, Virginie Royal, Alexandre Dugas, Jean-Philippe Lafrance

“…No neoplastic cells were found in the biopsy specimen; however, the pathology findings were compatible with immune complex glomerulonephritis with a predominantly membranous distribution, a pattern suggestive of lupus nephritis. The mass effect was apparently due to a dense interstitial lymphocytic infiltrate resulting in a pseudotumor. …”

Bilateral Telencephalic Gliomatosis Cerebri in a Dog by Mario Ricciardi, Antonio De Simone, Pasquale Giannuzzi, Maria Teresa Mandara, Alice Reginato, Floriana Gernone

“…MRI revealed diffuse, bilateral, and symmetric T2 and FLAIR hyperintensities in the parieto-occipital white matter and corpus callosum. No mass effect or contrast enhancement was noted. Analysis of cerebrospinal fluid revealed normal protein content and mild mononuclear pleocytosis. …”
