#1
Asmaa Gaber Abdou, Doha MaherTaie
Langerhans cell histiocytosis (LCH) is a rare disease characterized by a proliferation of cells that show immunophenotypic and ultrastructural similarities with antigen-presenting Langerhans cells of mucosal sites and skin. LCH in adults is rare, and there are still many undiagnosed/misdiagnosed patients. We describe LCH involvement of the perianal region of a 33-year-old male with a previous history of diabetes insipidus. The differential diagnosis and all the reported cases of LCH of the perianal skin involvement since its description in 1984 till 2016 are discussed...

We report the development of optical coherence tomography- (OCT) based angiography (OCTA) to image blood flow within microcirculatory tissue beds in human oral cavity in vivo with a field of view at 10 mm × 10 mm. Three-dimensional (3D) structural and vascular images of labial mucosa tissue are obtained at a single 3D acquisition. Pathologic mucosal sites with mouth ulcers are examined using the OCT tomograms and angiograms, upon which to monitor the lesion healing process over a period of 2 weeks. Quantitative metrics of the capillary loop density within the lamina propria layer are evaluated, providing statistically significant difference between healthy and diseased conditions over time...

OBJECTIVE: An accurate and reliable method for measuring venous leg ulcer (VLU) area is important in assessing treatment effects. The new three-dimensional (3D) LifeViz digital imaging system (QuantifiCare S.A., Valbonne, France) combines a compact, easy to use stereovision camera and image management software to provide 3D medical images. The aim of this prospective study was to investigate whether the 3D LifeViz digital imaging system could be considered a suitable alternative to manual transparent wound tracing for the measurement of VLU area and 4-week healing rates...

A 73-year-old female was admitted to our hospital with abdominal pain and diarrhea. Computed tomography detected distension of the small intestine. A palmar erythema, multiple oral ulcers, and desquamation of the fingers appeared after hospitalization. Small-bowel endoscopic images showed multiple ulcers. We attributed this case to infection with Yersinia pseudotuberculosis based on the changes in Y. pseudotuberculosis antibody titers throughout the course of the illness. This report is valuable, as it illustrates the endoscopic characteristics of a Y...

Background -Acute aortic syndromes (AAS) are rare and severe cardiovascular emergencies with unspecific symptoms. For AAS, both misdiagnosis and over-testing are key concerns, and standardized diagnostic strategies may help physicians to balance these risks. D-dimer (DD) is highly sensitive for AAS, but is inadequate as a standalone test. Integration of pre-test probability assessment (PPA) with D-dimer (DD) testing is feasible, but the safety and efficiency of such diagnostic strategy are currently unknown...

BACKGROUND: Understanding immune phenotypes and human gastric disease in situ requires an approach that leverages multiplexed immunohistochemistry (mIHC) with multispectral imaging to facilitate precise image analyses. METHODS: We developed a novel 4-color mIHC assay based on tyramide signal amplification that allowed us to reliably interrogate immunologic checkpoints, including programmed death-ligand 1 (PD-L1), cytotoxic T cells (CD8(+)T) and regulatory T cells (Foxp3), in formalin-fixed, paraffin-embedded tissues of various human gastric diseases...

INTRODUCTION: True hepatic artery aneurysms (HAAs) are rare, and when complicated by gastrointestinal haemorrhage, it becomes an even rarer disease entity. The mortality is high and imaging may fail to provide the diagnosis. We present a case of a true hepatic artery aneurysm complicated by a fistula to the duodenum which was first recognised during surgery. PRESENTATION OF CASE: A 77-year-old man presented with upper gastrointestinal haemorrhage. Upper endoscopy revealed an ulceration in the duodenal bulb, which was refractory to endoscopic treatment...

For wheelchair users, a common injury is a sitting-acquired pressure ulcer (PU) which typically onsets near the interface between the ischial tuberosity (IT) and the overlying soft tissues. The risk of developing PUs can be reduced considerably if an adequate cushion is placed on the wheelchair in order to protect tissues from PUs by minimising interface mechanical loads between the body and cushion and also, exposure to internal soft tissue loads. In this work, we studied the biomechanical performances of an off-loading (OL) cushion with limited adjustability, in comparison to a standard foam cushion and a fully adjustable air-cell-based (ACB) cushion...

OBJECTIVE: to evaluate the effects of increasing pressures on the cutaneous blood flow in the skin of pigs. METHODS: we conducted an experimental study in pigs submitted to subcutaneous magnetic implants (n=30). After healing, were applied external magnets with varying magnetic forces to the skin, generating compression. We evaluated the cutaneous circulation of the skin under compression by the Laser Speckle Contrast Imaging (LSCI) technique. We measured the depth of the implants by ultrasonography, and applied computational simulations to the calculation of the different pressure values, considering the different distances between implants and external magnets...

Long-standing intestinal inflammation in patients with inflammatory bowel disease (IBD) induces dysplastic change in the intestinal mucosa and increases the risk of subsequent colorectal cancer. The evolving endoscopic techniques and technologies, including dye spraying methods and high-definition images, have been replacing random biopsies and have been revealed as more practical and efficient for detection of dysplasia in IBD patients. In addition, they have potential usefulness in detailed characterization of lesions and in the assessment of endoscopic resectability...

OBJECTIVES: Differentiating ulcerative colitis (UC) and Crohn's disease (CD) can be clinically challenging, especially in children. Granulomatous inflammation has traditionally been attributed to CD. Crypt-associated giant cells and granulomas, however, have been observed in colonic biopsies of UC patients. This phenomenon has not been described in the upper gastrointestinal (UGI) tract with UC. METHODS: Seven pediatric UC patients with granulomatous UGI (gUGI) lesions were identified...

A 61-year-old male was referred with a week's history of a painful and swollen left eye. Examination revealed normal visual acuities, left proptosis and global restriction of ocular ductions, and subretinal fluid at the macula. CT imaging confirmed thickening of the posterior scleral coat, with an associated choroidal effusion. Serology revealed positive antinuclear antibodies with a centromere staining pattern; subsequent rheumatology review revealed extensive telangiectasia with digital ulceration in both hands, and a diagnosis of limited cutaneous systemic sclerosis was made...

INTRODUCTION: The most common cause of chronic hypercalcemia is primary hyperparathyroidism (PHPT). However, owing to the diverse presentation of hypercalcemia, the diagnosis often goes unnoticed culminating as a continuum of recurrence of symptoms. Nephrolithiasis, decreased bone mineral density and peptic ulcer disease are the main clinical sequelae. Among the causes of PHPT 80% are caused by parathyroid adenomas (PA). However, only rarely, these adenomas are found ectopically. PRESENTATION OF CASE: We present the case of a 66-year-old female with a history of recurrent renal stones and peptic ulcer disease...

Ulcer tissue segmentation is of immense importance in helping medical personnel to assess wounds. This paper introduces a new computational framework employing state-of-the-art image processing techniques to segment pressure ulcer tissue structures from color images. The framework integrates a visual appearance model of an observed input image with prior color information from an available database of previously stored color RGB images. The following four processing steps are performed. First, to minimize the execution time and enhance the segmentation accuracy, a region-of-interest (ROI) of the whole ulcer area is automatically identified based on contrast changes...

BACKGROUND AND AIMS: Patients with longstanding ulcerative colitis (UC) are at increased risk of developing colorectal neoplasia. Chromoendoscopy (CE) increases detection of lesions, and Kudo pit pattern classification I and II have been suggested to be predictive of benign polyps in UC. Little is known on the use of this classification in non-magnified high-definition (HD) (virtual) CE and narrow-band Imaging (NBI), or on the interobserver agreement. The aim of this pilot study was to assess the diagnostic accuracy and the interobserver agreement of the Kudo pit pattern classification in UC patients undergoing surveillance with methylene blue CE or NBI in a multicenter study...

Natural orifice transluminal endoscopic surgery (NOTES) is a novel surgical approach, currently performed for an array of conditions. Endoscopic procedures offer significant benefits, including lower cost, no surgical incisions, and shorter hospital stays. These advantages align with the current trends in health care, namely a push for "cost-effective care." There are a multitude of health issues which are now being addressed by the endoscopic surgical approach, including peroral endoscopic myotomy (POEM), which is a relatively new technique used in the treatment of achalasia...

PURPOSE: Most of the patients who receive myeloablative therapy prior to stem cell transplantation develop oral mucositis (OM). This adverse reaction manifests as oral mucosal erythema and ulcerations and may require high doses of morphine for pain alleviation. OM may also interfere with food intake and result in weight loss, a need for parenteral nutrition, and impaired quality of life. To date, there have been very few studies of evidence-based interventions for the prevention of OM...
