Stain normalization in digital pathology: Clinical multi-center evaluation of image quality.

In digital pathology, the final appearance of digitized images is affected by several factors, resulting in stain color and intensity variation. Stain normalization is an innovative solution to overcome stain variability. However, the validation of color normalization tools has been assessed only from a quantitative perspective, through the computation of similarity metrics between the original and normalized images.

Total embedding of spermatic cord and hilar soft tissue in orchiectomy for seminoma: does the extensive sampling improve pathologic risk factors?

Pure seminomas represent the majority of testicular germ cell tumors and accurate diagnosis and staging require an accurate sampling of radical orchiectomy specimens. The aim of our study is to find the most informative gross sampling method for orchiectomy specimens. We performed the extensive sampling of 88 radical orchiectomy specimens embedding in their entirety testicular hilum, rete testis, hilar soft tissue, and spermatic cord.

Sinonasal teratocarcinosarcoma treated with surgery and proton beam therapy: clinical, histological aspects and differential diagnosis of a new case.

Sinonasal teratocarcinosarcoma is a rare aggressive malignant tumor with a primary setting involving the nasal cavity followed by the ethmoid sinus and maxillary sinus. It accounts for approximately 3% of all head and neck cancers and less than 1% of all tumors. Nasal obstruction, recurrent epistaxis and headache represent the typical clinical presentation.

Generalized Arterial Calcification of Infancy Type 1 (GACI1): Identification of a Novel Pathogenic Variant (c.1715T>C (p.Leu572Ser)).

Generalized Arterial Calcification of Infancy (GACI) is a rare disease inherited in a recessive manner, with severe and diffuse early onset of calcifications along the internal elastic lamina in large and medium size arteries. The diagnosis results are from clinical manifestations, imaging, histopathologic exams, and genetic tests. GACI is predominantly caused by biallelic pathogenic variant in the gene (GACI1, OMIM#208000) and, to a lesser extent, by pathogenic variants in the gene (GACI2, OMIM#614473).

How Can We Treat Vulvar Carcinoma in Pregnancy? A Systematic Review of the Literature.

According to our systematic literature review (PRISMA guidelines), only 37 vulvar squamous cell carcinomas (VSCCs) were diagnosed during pregnancy (age range: 17-41 years). The tumor size range was 0.3-15 cm.

Prospective validation of the International Warfarin Pharmacogenetics Consortium algorithm in high-risk elderly people (VIALE study).

We assessed the predictive accuracy of the Warfarin Pharmacogenetics Consortium (IWPC) algorithm in a prospective cohort of 376 high-risk elderly patients (≥65 years) who required new treatment with warfarin for either medical (non valvular atrial fibrillation) or surgical conditions (heart valve replacement), had ≥1 comorbid conditions, and regularly used ≥2 other drugs. Follow-up visits were performed according to clinical practice and lasted for a maximum of 1 year. Two hundred and eighty-three (75%) patients achieved a stable maintenance dose.
