18F-FDG and 68GA-Prostate-Specific Membrane Antigen PET/CT Perform Better Than CT Alone in Restaging Papillary Renal Cell Carcinoma Recurrence.

Renal cell carcinoma (RCC) shows variable FDG uptake; recently, PET/CT with prostate-specific membrane antigen (PSMA)-target radiotracers was demonstrated to be a promising tool in staging and restaging of RCC patients. We describe the case of a 77-year-old man with a lung metastasis of papillary RCC missed by CT scan who successfully underwent [18F]FDG PET/CT restaging. Targeted therapy with sunitinib was administered.

A Nodular Pink Lesion with an Uncommon Diagnosis: A Quiz.

Blue nevus of the nail: A case report and review.

Blue nevus (BN), in all its clinical variants, rarely affects the nail bed. This leads to difficulty in the diagnosis of BN within the nail bed as well as to challenges with regard to its treatment and follow-up management, not solely attributed to the intrinsic difficulty of the anatomical site. We present the first case in the literature of an acquired cellular BN entirely confined within the nail bed, in a female Caucasian patient.

Isolated fronto-ethmoidal allergic fungal rhinosinusitis: case report and review of the literature.

Background And Aim Of The Work: Fungal rhinosinusitis (FRS) is a clinical entity characterized by the presence of fungi within sino-nasal cavities that may occur in patients with normal or defective immunity. Allergic fungal rhinosinusitis (AFRS) is a form of non-invasive FRS that affects patients with an abnormal immuno-mediated response to fungal antigens. This article describes a case of isolated fronto-ethmoidal AFRS.

Osteonecrosis of the External Auditory Canal Associated With Oral Sorafenib Therapy: Sorafenib and Temporal Bone Osteonecrosis.

Objective: To present the first case of osteonecrosis of the external auditory canal associated with sorafenib treatment.

Patient: 58-year-old patient with right-sided otorrhea and otalgia was treated for otitis externa for 1 month without improvement. Otoscopic examination revealed a large defect in the inferior wall of the tympanic bone filled with skin debris and bony fragments.

Collagen proportionate area is an independent predictor of long-term outcome in patients with non-alcoholic fatty liver disease.

Background: Collagen proportionate area (CPA) measurement is a technique that quantifies fibrous tissue in liver biopsies by measuring the amount of collagen deposition as a proportion of the total biopsy area. CPA predicts clinical outcomes in patients with HCV and can sub-classify cirrhosis.

Aim: To test the ability of CPA to quantify fibrosis and predict clinical outcomes in patients with NAFLD.

Evaluating the association of serum ferritin and hepatic iron with disease severity in non-alcoholic fatty liver disease.

Background & Aims: Hyperferritinemia, with or without increased hepatic iron, represents a common finding in non-alcoholic fatty liver disease (NAFLD). However, it is unclear whether it reflects hepatic inflammation or true iron-overload and, in case the latter is confirmed, whether this influences disease progression. We therefore explored the association between serum ferritin, degree and pattern of hepatic iron deposition and liver disease severity in patients with NAFLD.

Immune Gene Expression Profile in Hepatocellular Carcinoma and Surrounding Tissue Predicts Time to Tumor Recurrence.

Background: The antitumor immune response may play a major role in the clinical outcome of hepatocellular carcinoma (HCC). We characterized the liver immune microenvironment by direct hybridization of RNA extracted from HCC and nontumorous tissues.

Methods: RNA was extracted from frozen liver tissue samples of HCC (T; = 30) and nontumorous tissues (NT; = 33) obtained from 38 patients.

Once in a Blue Moon … Rare Adnexal Tumor: From the Clinical and Videodermoscopical Aspects to the Mohs Surgery and the Histological Diagnosis.

The adnexal tumours are a very heterogeneous group of lesions, more and more studied in the literature. The squamoid eccrine ductal carcinoma (SEDC) is a rare malignant variant that combines ductal structures with squamous differentiation. We report a case of dermoscopic and histological diagnosis of SEDC, treated with Mohs Surgery and with no recurrence of a tumour after 12 months of follow up.

Transaminase abnormalities and adaptations of the liver lobule manifest at specific cut-offs of steatosis.

There is little documented evidence suggesting that liver fat is responsible for liver injury in the absence of other disease processes. We investigated the relationships between liver fat, aminotransferases and hepatic architecture in liver biopsies with simple steatosis. We identified 136 biopsies with simple steatosis from the Royal Free Hospital Archives with both clinical data and sufficient material.

Understanding the structural features of symptomatic calcific aortic valve stenosis: A broad-spectrum clinico-pathologic study in 236 consecutive surgical cases.

Background: With age, aortic valve cusps undergo varying degrees of sclerosis which, sometimes, can progress to calcific aortic valve stenosis (AVS). To perform a retrospective clinico-pathologic investigation in patients with calcific AVS.

Methods: We characterized and graded the structural remodeling in 236 aortic valves (200 tricuspid and 36 bicuspid) from patients with calcific AVS (148 males; average 72years); possible relationships between general/clinical/echocardiographic characteristics and the histopathologic changes were explored.

Inherited Structural Heart Diseases With Potential Atrial Fibrillation Occurrence.

Inherited cardiac diseases inducing structural remodeling of the myocardium sometimes develop arrhythmias of various kinds. Among these rhythm disturbances, atrial fibrillation is well known to frequently worsen the prognosis of the primary disorder by increasing morbidity and mortality, especially because of a higher rate of heart failure. In this manuscript, we have reviewed the literature on the most important inherited structural cardiac diseases in whose clinical history atrial fibrillation may occur fairly often.

Circulating IGF-I and IGFBP3 Levels Control Human Colonic Stem Cell Function and Are Disrupted in Diabetic Enteropathy.

The role of circulating factors in regulating colonic stem cells (CoSCs) and colonic epithelial homeostasis is unclear. Individuals with long-standing type 1 diabetes (T1D) frequently have intestinal symptoms, termed diabetic enteropathy (DE), though its etiology is unknown. Here, we report that T1D patients with DE exhibit abnormalities in their intestinal mucosa and CoSCs, which fail to generate in vitro mini-guts.
