The immunohistochemical detection of peroxiredoxin 1 and 2 in canine spontaneous vascular endothelial tumors.

J Vet Med Sci 2022 May 19. Epub 2022 May 19.

Laboratory of Veterinary Pathology, Joint Graduate School of Veterinary Sciences, Gifu University.

Peroxiredoxin (PRDX) is an antioxidant enzyme family with six isoforms (PRDX1-6). The main function of PRDXs is to decrease cellular oxidative stress by reducing reactive oxygen species, such as hydrogen peroxide, to HO. Recently, it has been reported that PRDXs are overexpressed in various malignant tumors in humans, and are involved in the development, proliferation, and metastasis of tumors. Read More

Efficacy of intravenous propranolol for life-threatening diffuse neonatal hemangiomatosis.

Pediatr Dermatol 2022 May 16. Epub 2022 May 16.

Department of Pediatrics, Hamamatsu University School of Medicine, Hamamatsu, Japan.

Oral propranolol is recommended as the first-line agent for infantile hemangioma requiring systemic treatment. Life-threatening complications such as obstructive infantile hemangioma of the airway or infantile hepatic hemangioma associated with high-output congestive heart failure are major indications for the consideration of early treatment. We present the case of an infant with life-threatening diffuse neonatal hemangiomatosis, including airway obstruction due to subglottic hemangioma, heart failure due to multiple hepatic hemangiomas with portohepatic venous shunts, and severe anemia due to continuous gastrointestinal bleeding, in which treatment with intravenous propranolol proved successful.

Womens Health (Lond) 2022 Jan-Dec;18:17455057221099018

Department of Neurology, Louis Pasteur University Hospital, Kosice, Slovakia.

Vertebral haemangioma is a benign vascular tumour mostly seen in the thoracic region of the spine. Spinal haemangiomas are usually asymptomatic and are discovered incidentally. In a few patients, however, aggressive vertebral haemangiomas can cause local pain, radicular pain or neurologic deficits, which result from neural compression. Read More

Insights Into Vascular Anomalies, Cancer, and Fibroproliferative Conditions: The Role of Stem Cells and the Renin-Angiotensin System.

Front Surg 2022 27;9:868187. Epub 2022 Apr 27.

Gillies McIndoe Research Institute, Wellington, New Zealand.

Cells exhibiting embryonic stem cell (ESC) characteristics have been demonstrated in vascular anomalies (VAs), cancer, and fibroproliferative conditions, which are commonly managed by plastic surgeons and remain largely unsolved. The efficacy of the mTOR inhibitor sirolimus, and targeted therapies that block the Ras/BRAF/MEK/ERK1/2 and PI3KCA/AKT/mTOR pathways in many types of cancer and VAs, further supports the critical role of ESC-like cells in the pathogenesis of these conditions. ESC-like cells in VAs, cancer, and fibroproliferative conditions express components of the renin-angiotensin system (RAS) - a homeostatic endocrine signaling cascade that regulates cells with ESC characteristics.

A New Nonlinear Photothermal Iterative Theory for Port-Wine Stain Detection.

Int J Environ Res Public Health 2022 May 5;19(9). Epub 2022 May 5.

Shaanxi Key Laboratory of Ultrasound, School of Physics and Information Technology, Shaanxi Normal University, Xi'an 710062, China.

The development of appropriate photothermal detection of skin diseases to meet complex clinical demands is an urgent challenge for the prevention and therapy of skin cancer. An extensive body of literature has ignored all high-order harmonics above the second order and their influences on low-order harmonics. In this paper, a new iterative numerical method is developed for solving the nonlinear thermal diffusion equation to improve nonlinear photothermal detection for the noninvasive assessment of the thickness of port-wine stain (PWS).

Is Infantile Hemangioma a Neuroendocrine Tumor?

Int J Mol Sci 2022 May 5;23(9). Epub 2022 May 5.

BRIC, UMR 1312, Inserm, University Bordeaux, F-33076 Bordeaux, France.

Infantile hemangioma (IH) is the most common infantile tumor, affecting 5-10% of newborns. Propranolol, a nonselective β-adrenergic receptor (ADRB) antagonist, is currently the first-line treatment for severe IH; however, both its mechanism of action and its main cellular target remain poorly understood. Since betablockers can antagonize the effect of natural ADRB agonists, we postulated that the catecholamine produced in situ in IH may have a role in the propranolol response. Read More

Classification of hepatic cavernous hemangioma or hepatocellular carcinoma using a convolutional neural network model.

J Gastrointest Oncol 2022 Apr;13(2):787-791

Department of Interventional Radiology, Tangdu Hospital, Fourth Military Medical University, Xi'an, China.

Background: Computed tomography (CT) is a common imaging technique for diagnosis of liver tumors. However, the intensity similarity on non-contrast CT images is small, making it difficult for radiologists to visually identify hepatic cavernous hemangioma (HCH) and hepatocellular carcinoma (HCC). Recently, convolutional neural networks (CNN) have been widely used in the study of medical image classification because more discriminative image features can be extracted than the human eye.

Effect of an Ultrahigh b Value of 3000 s/mm and the Minimal Echo-time on Image Quality and the T2 Shine-through Effect in Diffusion-weighted Imaging of the Liver at 3T: Phantom and Clinical Pilot Studies.

Magn Reson Med Sci 2022 May 11. Epub 2022 May 11.

Department of Radiology, Faculty of Medicine, Kyorin University.

Purpose: To assess the effect of an ultrahigh b value of 3000 s/mm and the minimal TE of 53 ms on image quality and T2 shine-through effect in liver diffusion-weighted imaging (DWI) using a 3-Tesla MRI scanner with a peak gradient of 100 mT/m.

Methods: At b values of 1000 and 3000 s/mm and at the minimal (44-53 ms) and routine TEs (70 ms), DWI of our original phantom and liver DWI in 10 healthy volunteers and 26 patients with 35 hepatic hemangiomas were acquired with this scanner, and the quantified SNR of the phantom and the hepatic parenchyma in the volunteers and the contrast-to-noise ratio (CNR) of the hepatic hemangiomas were calculated; two independent readers qualitatively graded the overall image quality in the volunteers and determined the presence or absence of the T2 shine-through effect related to the hemangiomas in the patients. We compared the SNR and subjective overall image quality between the minimal and routine TEs and the CNR and incidence of the T2 shine-through effect between b values of 1000 and 3000 s/mm.
