In venous leg ulcers (VLU), risk factors and comorbidities may affect prognosis and recurrence. Aim of this paper was to assess risk factors and most frequent medical conditions in venous ulcers....
This a single center retrospective study from January 2017 to December 2020 on 172 patients with VLU admitted at our Center for Ulcer therapy in San Filippo Neri Hospital in Rome; data about medical h...
Incidence of VLU in patients over 65 was twice that in patients under 65 and woman were affected by VLU more than men (59.3% vs. 40.7%; P<0.001); more significant comorbidities were arterial hypertens...
Age, female sex, arterial hypertension, heart disease and COPD were significant risk factors. Thinking "globally" to the patient rather than only taking the ulcer into account is the key for a long-la...
Solitary rectal ulcer syndrome (SRUS) is a benign and chronic disorder well known in young adults that is characterized by a series of symptoms such as rectal bleeding, copious mucus discharge, prolon...
To define the clinical characteristics of oral ulceration (OU) in Behçet's disease (BD), to allow differentiation from other causes of OU, including aphthous ulcers, by an International Delphi consult...
Round 1. 40 clinical images of OU in BD, recurrent aphthous stomatitis (RAS), inflammatory bowel disease (IBD) and mucous membrane pemphigoid (MMP) were shown. Participants answered, independently, wh...
This study has shown clear differentiation between BD, IBD and MMP ulcers when defining them by phenotype through clinical images only. On the other hand, no differentiation between RAS and BD ulcers ...
New clinical guidance for Health Care Professionals (HCP) on how to recognise a BD ulcer has been proposed. This should elucidate an earlier diagnosis, quicker access to treatment and control of the d...
Marginal ulcer bleeding (MUB) is a complication that can occur following several types of surgery. However, few studies exist on it. Therefore, this study aimed to compare the clinical outcomes of MUB...
Between January 2013 and December 2017, 5,076 patients underwent emergent esophagogastroduodenoscopy for suspected upper gastrointestinal bleeding. We retrospectively reviewed and analyzed the medical...
A total of 64 and 678 patients were diagnosed with MUB and PUB, respectively, on emergent esophagogastroduodenoscopy, and 62 and 124 patients with MUB and PUB, respectively, were selected after PSM. R...
MUB showed a severe clinical course than PUB. Therefore, MUB should be managed more cautiously, especially for large ulcers and pancreatic surgery. Prophylactic PPI administration may be helpful in re...
Increased C-reactive protein (CRP) is used to diagnose and predict response to treatment in acute severe ulcerative colitis (UC)....
To investigate the connection between CRP elevation and deep ulcers in UC....
Patients with active UC were enrolled in a multicenter prospective cohort and a retrospective cohort of consecutive patients undergoing colectomy from 2012 to 2019....
Forty-one (9 (22%) with deep ulcers) patients were included in the prospective cohort: 4/5 (80%) patients with CRP > 100 mg/L, 2/10 (20%) patients with CRP between 30 and 100 mg/L and 3/26 (12%) patie...
CRP elevation is a robust surrogate marker for presence of deep ulcers in UC. Elevated CRP or presence of deep ulcers could influence the choice of medical therapy in acute severe UC....
A 74-year-old woman presented herself at the outpatient clinic for dermatology with three temporoparietal ulcers on her scalp which are diagnosed as complications of temporal arteritis. The core sympt...
The appropriate location for biopsy collection in ulcerative colitis is unknown....
We aimed to determine the location for biopsy collection in the presence of ulcers which yields the highest histopathological score....
This prospective cross-sectional study enrolled patients with ulcerative colitis and ulcers in the colon. Biopsy specimens were obtained at the edge of the ulcer; at a distance of one open forceps (7-...
A total of 19 patients were included. Decreasing trends with distance from the ulcer edge ( P < 0.0001) were observed. Biopsies procured from the edge of the ulcer (location 1) yielded a higher histop...
Biopsies from the ulcer edge yield higher histopathological scores than biopsies next to the ulcer. In clinical trials with histological endpoints, biopsies should be obtained from the ulcer edge (if ...
The myriad presentations of ulcerative sexually transmitted infections, other than genital herpes and syphilis, challenge even the most astute clinician given the considerable overlap in clinical pres...

To assess the effects of hydrogel wound dressings on the healing of venous leg ulcers in any care setting....
In May 2021, we searched the Cochrane Wounds Specialised Register, CENTRAL, Ovid MEDLINE, Ovid Embase and EBSCO CINAHL Plus. We also searched clinical trials registries for ongoing and unpublished stu...

We included four RCTs (10 articles) in a qualitative analysis. Overall, 272 participants were randomised, in sample sizes ranging from 20 to 156 participants. The mean age of the included population i...
There is inconclusive evidence to determine the effectiveness of hydrogel dressings compared with gauze and saline, alginate dressing, manuka honey or hydrocolloid on venous leg ulcer healing. Practit...
