The Mirror Theory: Parallels between Open Angle and Angle Closure Glaucoma.

Glaucoma is a widespread ophthalmological disease, with a high impact and frequent visual morbidity. While the physiopathology of the two types of primary glaucoma (open angle and angle closure) has been studied, there seems to be little relationship between the two. In this study, we gather clinical and preclinical data to support the idea that the two primary glaucomas are "mirrored" in terms of morphological parameters and disease physiopathology.

Diagnostic Performance of an Artificial Intelligence Model Based on Contrast-Enhanced Ultrasound in Patients with Liver Lesions: A Comparative Study with Clinicians.

Contrast-enhanced ultrasound (CEUS) is widely used in the characterization of liver tumors; however, the evaluation of perfusion patterns using CEUS has a subjective character. This study aims to evaluate the accuracy of an automated method based on CEUS for classifying liver lesions and to compare its performance with that of two experienced clinicians. The system used for automatic classification is based on artificial intelligence (AI) algorithms.

The Clinical Value of Multimodal Ultrasound for the Differential Diagnosis of Hepatocellular Carcinoma from Other Liver Tumors in Relation to Histopathology.

Recent advances in the field of ultrasonography offer promising tools for the evaluation of liver tumors. We aim to assess the value of multimodal ultrasound in differentiating hepatocellular carcinomas (HCCs) from other liver lesions. We prospectively included 66 patients with 72 liver tumors.

Cervical intranodal schwannoma - a rare diagnosis.

Intranodal schwannoma is a rare benign tumor, which originates from the peripheral nerve sheath (Schwann cells), fewer cases being reported with lymphatic involvement. We present the case of a middle-aged female patient, with one-year growing mass in the lateral-cervical area, in intimate relation with the vascular package of the neck. Preoperative cervical computed tomography examination showed the tumor features.

Role of Contrast-Enhanced Ultrasonography in Hepatocellular Carcinoma by Using LI-RADS and Ancillary Features: A Single Tertiary Centre Experience.

Clinical utility of ancillary features (AFs) in contrast-enhanced ultrasound (CEUS) Liver Imaging Reporting and Data System (LI-RADS) is yet to be established. In this study, we assessed the diagnostic yield of CEUS LI-RADS and AFs in hepatocellular carcinoma (HCC). We retrospectively included patients with risk factors for HCC and newly diagnosed focal liver lesions (FLL).

EndoCuff-Assisted Colonoscopy Versus Standard Colonoscopy in Colonic Polyp Detection-Experience from a Single Tertiary Centre.

Background: Standard colonoscopy fails to visualize the entire colon mucosa and consequently a significant amount of polyps are still being missed. New device, such as EndoCuff, have been developed to improve mucosal visualisation, hence the quality in colonoscopy. The aim of this study was to assess the diagnostic yield of EndoCuff-assisted colonoscopy in comparison with standard colonoscopy by taking into consideration several quality indicators.

Ultrasound biomicroscopy as a vital tool in occult phacomorphic glaucoma.

Ultrasound is a fundamental tool used in all medical specialties, including ophthalmology. Nowadays, ultrasound biomicroscopy (UBM), a method with higher resolution, allows the investigation of in vivo details of the anterior segment of the eye at microscopic resolution. The examination is especially useful in patients with secondary glaucoma that involves a lens component such as phacomorphic glaucoma and occult phacomorphic glaucoma (OPG).

Issues and controversies in esophageal inlet patch.

The proximal esophagus is rarely examined, and its inspection is often inadequate. Optical chromoendoscopy techniques such as narrow band imaging improve the detection rate of inlet patches in the proximal esophagus, a region in which their prevalence is likely underestimated. Various studies have reported correlations between these esophageal marks with different issues such as Barrett's esophagus, but these findings remain controversial.

Current strategies for malignant pedunculated colorectal polyps.

Despite significant advances in imaging techniques, the incidence of colorectal cancer has been increasing in recent years, with many cases still being diagnosed in advanced stages. Early detection and accurate staging remain the main factors that lead to a decrease in the cost and invasiveness of the curative techniques, significantly improving the outcome. However, the diagnosis of pedunculated early colorectal malignancy remains a current challenge.

Narrow band imaging endoscopy for detection of precancerous lesions of upper gastrointestinal tract.

Gastric cancer (GC) is an important health problem despite the advances in surgery and chemotherapy and although the incidence is decreasing, GC is still considered the second most common cause of deceases produced by cancer. Survival rates in gastric cancer are low, mainly because most patients are often diagnosed in late stages. The current interest in the diagnostic of GC is the detection of early gastric cancer.

Severe asymptomatic coronary obstruction in chronic hemodialysed patient - a case report.

Arterial stiffness and vascular calcifications are independent predictors of cardiovascular morbidity and mortality in the chronic kidney disease (CKD) stage 5D population. According to the guidelines, patients on renal replacement therapy represent a very high cardiovascular risk class. We report the case of a 67-year-old hypertensive male patient, known with CKD stage 5D on hemodialysis (three times per week), secondary bone mineral disease, admitted for progressive right leg pain.

Narrow band imaging with near-focus mode for colorectal polyps' characterization.

Conventional white light endoscopy is far from being an ideal tool to detect, characterize, and confirm the nature of colorectal lesions in order to indicate targeted biopsies or polyp resections only when necessary. Minimally invasive imaging techniques have gradually emerged to reveal previously unseen abnormalities to the operator during endoscopic examination. In this respect, technology and applications of narrow band imaging (NBI) are rapidly evolving.

Confocal laser endomicroscopy in ulcerative colitis: a longitudinal study of endomicroscopic changes and response to medical therapy (with videos).

Background And Aims: Confocal laser endomicroscopy enables real-time in vivo microscopy during endoscopy and can predict relapse in patients with inflammatory bowel disease in remission. However, little is known about how endomicroscopic features change with time. The aim of this longitudinal study was to correlate colonic confocal laser endomicroscopy (CLE) in ulcerative colitis with histopathology and macroscopic appearance before and after intensification of medical treatment.

Tumor neoangiogenesis detection by confocal laser endomicroscopy and anti-CD105 antibody: Pilot study.

Aim: To evaluate neoangiogenesis in patients with colon cancer by two fluorescently labeled antibodies on fresh biopsy samples imaged with confocal laser endomicroscopy (CLE).

Methods: CLE is an imaging technique for gastrointestinal endoscopy providing in vivo microscopy at subcellular resolution. An important question in validating tumor angiogenesis is what proportion of the tumor vascular network is represented by pre-existing parent tissue vessels and newly formed vessels.

Synergistic approach to patient dialysate.

The stress a patient is subjected to during dialysis treatment can be reduced by using a synergetic approach by the medical team. The integration into therapy of the positive psychical resources such as: active positive coping mechanisms, individual or family mental resilience, improvement of the image and self-esteem, better tolerance to frustration can represent an important part in the improvement of the patient's quality of life, determination of a positive approach of the situations both for him and close friends and relatives.

Determining factors of diuresis in chronic kidney disease patients initiating hemodialysis.

Background: Patients with stage 5 chronic kidney disease (CKD) begin chronic hemodialysis with variable diuresis levels correlated to a comparable low glomerular filtration rate. Residual diuresis influences long-term evolution of the hemodialyzed patient, modifying the prognosis even if optimal Kt/ V is achieved.

Aim Of The Study: The present study emphasizes the main determining factors of diuresis in a cohort of stage 5 CKD subjects at the beginning of hemodialysis.

Endomicroscopy with Fluorescent CD105 Antibodies for "In Vivo" Imaging of Colorectal Cancer Angiogenesis.

The aim of this case report was to evaluate the feasibility of in vivo acquisition of microscopic images using fluorescent CD105 antibodies for molecular imaging in human colorectal cancer. After excluding the presence of tissue autofluorescence, the antibody solution was topically administered through a spray-catheter. The targeted area was analyzed by eCLE and images were recorded.

Thromboangiitis obliterans - case report.

Thromboangiitis obliterans (Buerger'€™s disease) represents an inflammatory disease of limbs'€™ small arteries and veins causing vascular thrombosis, and partial or total obstruction. It affects mostly male gender aged 40 years old. The peculiarity of our case is underlined by presenting a 62 years, chronic tobacco user and not compliant female patient known with thromb oangiitisobliterans for almost 15 years.

Intra-peritoneal chronic loculation in peritoneal dialysis patients - a new medical management approach.

Peritoneal dialysis (PD) limitation as renal replacement therapy is mostly due to peritonitis and complications. Formation and persistence of intra-abdominal loculations is often under-diagnosed. Encapsulated peritoneal sclerosis (EPS) is a life-threatening complication, but malnutrition, recurrent peritonitis and early membrane failure are insidious enemies that need to be emphasized.

Evaluation of new morphometric parameters of neoangiogenesis in human colorectal cancer using confocal laser endomicroscopy (CLE) and targeted panendothelial markers.

The tumor microcirculation is characterized by an abnormal vascular network with dilated, tortuous and saccular vessels. Therefore, imaging the tumor vasculature and determining its morphometric characteristics represent a critical goal for optimizing the cancer treatment that targets the blood vessels (i.e.

Calcific uremic arteriolopathy in hemodialyzed patients.

In the present article, we discuss the case of 67-year-old female patient diagnosed with inferior limbs calciphylaxis and hemodialyzed since 2006. The clinical manifestations and pathological lab findings are typical for this rare and extremely severe complication in chronic hemodialyzed individuals. The favorable treatment response to sodium thiosulfate, not often used as elected therapy in international studies, represents the particularity of the case.

Oral treatment of metabolic acidosis in hemodialyzed patients and the implications on the hemodynamic status.

Unlabelled: Metabolic acidosis slowly develops during renal impairment natural evolution towards ESRD and represents an important contributing factor of CKD progression. Although, several clinical and experimental trials reported the major impact of metabolic acidosis on CKD evolution, the pathophysiology mechanism remains a matter of debate. Furthermore, international guidelines do not impose a specific treatment scheme for metabolic acidosis in CKD patients, and metabolic acidosis is not fully compensated once hemodialysis starts.

Confocal laser endomicroscopy for the morphometric evaluation of microvessels in human colorectal cancer using targeted anti-CD31 antibodies.

Introduction: Numerous anti-angiogenic agents are currently developed to limit tumor growth and metastasis. While these drugs offer hope for cancer patients, their transient effect on tumor vasculature is difficult to assess in clinical settings. Confocal laser endomicroscopy (CLE) is a novel endoscopic imaging technology that enables histological examination of the gastrointestinal mucosa.

Functional status of chronic renal replacement therapy in elderly patients--comparison between hemodialysis and peritoneal dialysis.

Unlabelled: Nowadays, nephrologists are confronted with an increasing number of elderly patients diagnosed with end-stage renal disease (ESRD) in need of dialysis. The benefits of renal replacement therapy are uncertain in this group of patients. Most studies show that the quality of life and survival of elderly dialyzed patients are worse than in younger patients because of multiple comorbidities.

Comparative evolution of hemodialysis vs. peritoneal dialysis in elderly.

Unlabelled: The prevalence of treated patients with end-stage renal disease (ESRD) has considerably increased in the last decade mainly in the elderly age groups. The type of optimal mode of dialysis therapy in elderly is difficult to establish and most studies comparing hemodialysis and peritoneal dialysis in elderly failed to demonstrate the superiority of one therapy versus the other. The present article uses Charlson Co morbidity Index to compare evolution of an elderly population in HD versus PD.
