A Rare Case of Sitagliptin‐Induced Oral Ulceration

ABSTRACTIntroductionThere is a spectrum of adverse drug reactions in the oral cavity, ranging from drug‐induced xerostomia to the development of severe mucosal disorders including extensive ulceration and mucositis. In relation to drug‐induced ulcerations, there are previously established adverse effects of some medications such as nicorandil and low‐dose methotrexate. There are however, limited reports on the effects of DD4 Inhibitors (Gliptins) on the oral cavity.AimThe aim of this case report is to highlight the rare finding of oral ulceration as an adverse effect of sitagliptin therapy. This case will add to the literature and promote awareness to our colleagues about the implications of gliptin therapy.MethodsThe case details an 87‐year‐old male who attended our oral surgery clinic with a persistent ulcer of 6 weeks on the lateral border of the tongue. The patient was started on Sitagliptin for management of his diabetes mellitus 4 months prior to the development of the lesion. Haematinic investigations also revealed a diagnosis of iron deficiency anaemia. The sitagliptin was stopped and the patient was treated for iron deficiency anaemia. This resulted in complete resolution of the ulcer. We also conducted a literature search which reveals only four reported incidences of gliptin induced oral ulceration.ConclusionThis case highlights that oral ulceration, or mucosal changes are likely adverse effects of sitagliptin therapy. This emphasises the importance of undertaking thorough history and correlating their systemic conditions to clinical findings to achieve an accurate diagnosis.

A Rare Presentation of Type 2 Lepra Reaction: Necrotizing Erythema Nodosum Leprosum with Extensive Ulceration

Background: Leprosy, primarily caused by Mycobacterium leprae, is a chronic infectious disease that mainly affects the skin and peripheral nerves. Type 2 leprosy reaction (ENL) is an immune complex-mediated complication characterized by inflammation of the skin, nerves, and other organs. A less common manifestation of ENL is necrotizing ENL, which presents with extensive skin necrosis and ulceration. This case report describes a rare presentation of necrotizing ENL with extensive ulceration in a young woman with borderline lepromatous leprosy. Case presentation: A 20-year-old female presented with multiple, progressively enlarging, painless ulcers on her right leg and painful reddish nodules on her left arm and left leg. She had a history of borderline lepromatous leprosy. Dermatological examination revealed madarosis, infiltration, nodules, hyperpigmentation macules, ulcers, and blackish crusts. Sensory testing showed hypoesthesia in the abdomen and back, and anesthesia in both lower arms and legs. Histopathological examination confirmed the diagnosis of necrotizing ENL. Conclusion: Necrotizing ENL is a rare and severe complication of leprosy. This case highlights the importance of early diagnosis and appropriate management with multi-drug therapy and corticosteroids to prevent significant morbidity and disability.

Bacteroides fragilis capsular polysaccharide A ameliorates ulcerative colitis in rat by recovering intestinal barrier integrity and restoring gut microbiota.

Bacteroides fragilis (B. fragilis) is a Gram-negative, obligate anaerobic, commensal bacterium residing in the human gut and holds therapeutic potential for ulcerative colitis (UC). Previous studies have indicated that capsular polysaccharide A (PSA) of B. fragilis is a crucial component for its effectiveness, possessing various biological activities such as anti-inflammatory, anti-tumor, and immune-modulating effects. We previously isolated and characterized the B. fragilis strain ZY-312 from the feces of a healthy breastfed infant, and extracted its PSA, named TP2. In this study, we explored the impact of TP2 on colonic inflammation and delved into its potential mechanisms. Initially, we used 2,4,6-trinitrobenzenesulfonic acid (TNBS) to induce colitis in rats and found that TP2 treatment significantly ameliorated TNBS-induced weight loss, increased clinical scores, extensive ulcers, and intestinal epithelial damage in UC rats. Further analysis revealed that TP2 effectively restored the intestinal barrier integrity in UC rats by regulating the expression of Muc-2, tight junction proteins (ZO-1, occludin, claudin-1, and claudin-2), as well as apoptosis-related proteins Bcl-2, BAX, and Cleaved-Caspase-3. Additionally, TP2 suppressed the expression of pro-inflammatory cytokines TNF-α, IL-1β, IL-6, and IL23, while promoting the secretion of anti-inflammatory cytokines IL-10 and IL-22, thereby inhibiting the occurrence of inflammation. TP2 also downregulated the phosphorylation levels of AKT and PI3K, effectively inhibiting the abnormal activation of the PI3K/AKT signaling pathway. More interestingly, 16S rRNA sequencing results showed that TP2 restored the ecological imbalance of the rat intestinal microbiota, with an increase in beneficial bacteria such as Lactobacillus and Limosilactobacillus observed in the treatment group. In conclusion, TP2 through the regulation of intestinal barrier-related cells and proteins, inhibition of apoptosis, modulation of inflammation-related cytokine levels, and control of abnormal activation of the PI3K/AKT signaling pathway, restores intestinal barrier integrity. Additionally, by reshaping the ecological imbalance of the gut microbiota, TP2 ultimately alleviates ulcerative colitis in rats.

Case Report: Upper gastrointestinal bleeding and multiorgan injury caused by ethylicin poisoning

Ethylicin is a pesticide with excellent bactericidal ability. The incidence of poisoning has increased in recent years with the widespread use of ethylicin in green agriculture, but reports are lacking. In this study, we described three cases of oral ethylicin poisoning. Patients developed severe upper gastrointestinal bleeding after oral administration of ethylicin. Gastroscopy showed extensive mucosal erosions and ulcerations in the esophagus, stomach, and duodenum. Impaired consciousness, multiorgan injury, irreversible shock, and cardiac arrest were observed in cases where larger doses of ethylicin were ingested. Patients were treated with comprehensive therapeutic measures, including total gastrointestinal decontamination, medications such as proton pump inhibitors and somatostatin to reduce gastric bleeding. Endoscopic hemostasis was performed when pharmacologic hemostasis was not effective. Parenteral nutritional support and organ function support were given. In patients’ follow up, esophageal stenosis and dysphagia during feeding was noted, which severely affected the quality of life. Ethylicin poisoning has been a public health problem and the awareness should be raised.

A Novel Intersection: Cytomegalovirus Gastritis Following Cemiplimab and Talimogene Laherparepvec in a Patient With Advanced Cutaneous Squamous Cell Carcinoma.

Cytomegalovirus (CMV) reactivation is a rare complication in patients treated with immune checkpoint inhibitors (ICIs), typically occurring after immunosuppressive therapy for immune-related adverse events (irAEs). Here, we report a unique case of severe CMV gastritis in a patient receiving cemiplimab, an anti-PD-1 antibody, and talimogene laherparepvec (T-VEC), an oncolytic virus, without prior irAEs or immunosuppressive treatment. A 63-year-old man with advanced cutaneous squamous cell carcinoma received cemiplimab for one year and a single T-VEC injection for recurrent disease. He presented with progressive dyspepsia, significant weight loss, and malnutrition requiring total parenteral nutrition. Endoscopy revealed extensive gastric ulceration, and biopsies confirmed CMV gastritis. Initial treatment with intravenous ganciclovir improved his viral load but provided minimal symptomatic relief. After six weeks of therapy, biopsies showed resolution of CMV infection, and the patient transitioned to oral valganciclovir for prophylaxis while resuming cancer treatment. This case highlights the potential for CMV reactivation in patients undergoing ICI therapy, even without prior immunosuppression or irAEs. Notably, the concurrent use of T-VEC raises questions about the interplay between oncolytic viruses, ICIs, and immune modulation. Although T-VEC is not known to directly cause CMV reactivation, its role in amplifying immune responses warrants further investigation. As ICIs and oncolytic viruses become increasingly integral in oncology, clinicians must remain vigilant for rare infectious complications like CMV reactivation. Further research is needed to elucidate mechanisms, identify risk factors, and optimize management strategies for these events.

Buruli Ulcer Transmission: Environmental Pathways and Implications for Dermatologic Care.

Buruli ulcer (BU) is a necrotizing skin and soft tissue disease caused by Mycobacterium ulcerans that is common in hot and humid climates. Mycobacterium ulcerans is a nontuberculous mycobacterium and ubiquitous acid-fast gram-positive bacillus known to thrive in aquatic environments and water insects. The mode of transmission to humans is poorly understood and varies by geography. Aquatic insects and mosquitoes have been studied as possible vectors for the transmission of M ulcerans and the development of BUs. Treatment involves a long course of antibiotics with possible surgical debridement with wide margins for extensive ulceration. In this article, we provide an overview of the etiology, pathogenesis, transmission, clinical presentation, prevention, and treatment of BUs.

Effect of past extensive ulcers on fecal calprotectin in ulcerative colitis

BackgroundUlcerative colitis (UC) causes extensive ulceration attributable to intestinal inflammation. This study investigated the effect of past extensive ulcers (PEUs) on fecal calprotectin (FC).MethodsThis retrospective, single-center, observational study included patients with UC with a Mayo endoscopic subscore of 0. UC with scarring or pseudopolyposis was defined as PEU and FC and fecal immunochemical occult blood test (FIT) values were compared. The marker levels of patients in the PEU and non-PEU groups were examined to assess clinical relapse within 12 months.ResultsOf the 61 included patients, 27 had UC with PEUs and 34 had UC without PEUs. Albumin, hemoglobin, and FIT values between groups were not significantly different; however, the C-reactive protein and FC values of the PEU group were significantly higher than those of the non-PEU group. The FC values of the clinical relapse and remission groups within 12 months differed significantly. The cutoff values for the prediction of relapse within 12 months for all patients (area under the curve [AUC], 0.709; 95% confidence interval [CI], 0.512–0.907) and the non-PEU group (AUC, 0.893; 95% CI, 0.724–1.000) were both 118 mg/kg.ConclusionsUC patients with PEUs have higher FC values than those without PEUs, even in remission. Additionally, FC values do not predict relapse in PEU patients. Therefore, FC may not be a sufficiently accurate biomarker for patients with PEUs.

Multidisciplinary Approach to Direct Segmental Artery Revascularization to Prevent Spinal Cord Ischemia Associated With Endovascular Thoracoabdominal Aortic Repair.

Despite advances in complex endovascular aortic repair techniques, spinal cord ischemia (SCI) remains a devastating complication following endovascular thoracoabdominal aortic repairs. Novel strategies to preserve key intercostal/lumbar arteries have been described. We report our early results of patients who underwent direct intercostal/lumbar artery revascularization using endovascular incorporation of fenestrations/branches or extra-anatomic approaches for fenestrated-branched endovascular aortic repairs (FBEVARs). A retrospective review of consecutive patients who underwent FBEVAR with intercostal/lumbar artery revascularization from 2018 to 2022 was performed. Patient characteristics, intraoperative details, and outcomes including SCI and branch occlusions were evaluated. Among 317 patients who underwent FBEVAR during the study period, 12 patients were included. Aortic pathologies consisted of degenerative aneurysms (33%), postdissection aneurysms (33%), extensive penetrating aortic ulcers with intramural hematoma (25%), and visceral patch pseudoaneurysm (8%). Full thoracoabdominal coverage was required in 8 patients and supraceliac coverage >10 cm was required in 4. Nine patients received endovascular incorporation, including directional branches (5/9), unstented fenestrations (2/9), and stented fenestration (2/9). Three patients received extra-anatomic subcutaneous femoral-to-radicular artery bypass using a composite graft of polytetrafluoroethylene (PTFE) and venous conduit. Our institutional SCI prevention protocol, consisting of prophylactic cerebral spinal fluid drain (CSFD) for high-risk patients, hemodynamic augmentation, and oxygen supplementation, was followed. Prophylactic CSFD was placed in 9 patients. One patient had unsuccessful drain placement attempts. The other 2 patients had previous unsuccessful attempts at CSFD placement. Median number of target vessels for FBEVAR was 4 with fluoroscopy time 66±31 minutes, contrast usage 109±51 ml. There were no in-hospital mortalities. Tarlov grade II SCI (ASIA grade D) were seen in 2 patients (1 endovascular and 1 extra-anatomic bypass), which resolved before discharge. At mean follow-up of 472±447 days, 3 patients had thrombosed intercostal/lumbar branches (1 extra-anatomic bypass and 2 endovascular branches) with no new SCI symptoms. In patients at high risk for SCI undergoing FBEVAR, direct revascularization of an intercostal or lumbar artery is feasible using endovascular or extra-anatomic bypass approach. Further studies are planned to identify key contributing segmental arteries and optimization of revascularization strategies. This study demonstrates the feasibility of Endovascular and extra-anatomic bypass to preserve segmental artery flow, aimed at reducing the risk of spinal cord ischemia during endovascular thoracoabdominal aortic repairs.

CT feature of irregular extensive ulceration as a predictor of liver metastasis in gastric gastrointestinal stromal tumours.

This study aimed to investigate whether the computed tomography (CT) finding of irregular extensive ulceration (IEU) can serve as a predictor of liver metastasis (LIM) in patients with gastric gastrointestinal stromal tumours (GISTs). This study retrospectively collected clinical and imaging data from 286 patients diagnosed with low-, intermediate-, or high-risk gastric GISTs, or primary lesions with LIM from three medical institutions. The patients were categorised into non-LIM and LIM groups according to whether they had synchronous or metachronous LIM. Multivariate logistic regression analyses were performed to identify significant predictors of LIM. Additionally, receiver operating characteristic (ROC) curve, subgroup, and pathologic-radiologic correlation analyses were conducted. A total of 124 patients were ultimately enroled. There were significant differences in sex, site, growth pattern, size, shape, ulceration and Ki-67 expression between LIM and non-LIM groups. ROC curve analysis demonstrated that IEU had the highest area under the curve for predicting LIM (AUC = 0.842; 95% CI: 0.760-0.924; p < 0.001). Multivariate analysis indicated that IEU was the most significant independent predictor of high LIM risk (OR = 88.62; 95% CI: 2.80-2803.54; p = 0.011). Subgroup analysis showed that IEU was more frequently associated with male sex, age ≤ 55 years, proximal sites, irregular shapes, mixed growth patterns, and a high Ki-67 expression. The CT feature of IEU serves as an independent predictor of LIM in gastric GISTs and is strongly associated with high Ki-67 expression. Question Accurate assessment of LIM risk in patients with gastric GISTs is crucial, yet current non-invasive predictors remain inadequate. Findings IEU on CT is an independent predictor of LIM, with high diagnostic accuracy and a significant association with elevated Ki-67 expression. Clinical relevance IEU on CT scans enables non-invasive risk stratification for LIM in gastric GISTs. Our study refined the assessment of ulceration types, highlighting significant heterogeneity, which may guide personalised treatment strategies.

Predictors of Successful Antibiotic Treatment of Osteomyelitis in Diabetic Forefoot Infection.

Osteomyelitis (OM) associated with diabetic foot ulceration (DFU) is a growing public health challenge worldwide. Since 2012 the number of patients presenting with DFU per year to our centre has doubled. This study aims to evaluate outcomes from outpatient antibiotic therapy (OPAT) in the management of OM in DFU patients. A retrospective analysis was performed of medical notes, radiology, and vascular laboratory reports for all DFU patients with OM treated from April 2016 to April 2020. Variables analyzed included age, gender, site of OM, WIfI Score (Wound Ischaemia and foot Infection Score), probe-to-bone test (PTB), imaging (X-ray/magnetic resonance imaging (MRI), co-morbidities (peripheral arterial disease (PAD), chronic kidney disease (CKD), hypertension (HTN), smoking, ischemic heart disease (IHD), and dyslipidaemia. Outcomes evaluated were healing, recurrent DFU, and freedom from amputation at 12months. 185 patients were admitted with 264 infected digits (Male 223; Female 41). The mean age was 66years. Only 168 (63.6%) were fully healed at 12months. Of the 96 patients who failed to heal, 43 underwent a repeat course of prolonged antibiotics without improvement. Factors associated with treatment failure were PAD, poorly controlled HbA1c and Deep or Extensive Ulcer or Gangrene. Extended outpatient antibiotic therapy (with an inpatient multidisciplinary approach) is an effective treatment for digital OM in DFU with a success rate of 63%. In recurrence, repeating prolonged antibiotics is unlikely to achieve healing. PAD, poorly controlled HbA1c and Deep or Extensive Ulcer or Gangrene are predictors of treatment failure.

Esophagitis in a Post-Liver Transplant Patient: A Case of Cytomegalovirus and Herpes Simplex Virus-1 Coinfection.

In post-liver transplant patients, esophagitis presents a diagnostic and management challenge due to the potential for opportunistic infections. This case describes a 59-year-old female with primary sclerosing cholangitis who underwent orthotopic liver transplantation six years prior. She presented with dysphagia, and her medical history included immunosuppression with prednisone, tacrolimus, and mycophenolate and a history of achalasia treated with esophageal peroral endoscopic myotomy. Esophagogastroduodenoscopy (EGD) revealed severe esophagitis with extensive ulcerations, raising suspicion for infectious etiologies such as cytomegalovirus (CMV) and herpes simplex virus-1 (HSV-1). The biopsy confirmed a rare coinfection of CMV and HSV-1, which was characterized histologically by viral cytopathic effects and immunohistochemical staining. Treatment with valganciclovir and temporary cessation of mycophenolate led to symptom resolution and viral clearance. Follow-up EGD demonstrated healing of esophageal ulcers, with subsequent findings of Candida esophagitis but no evidence of CMV or HSV recurrence. This case highlights the importance of early endoscopic evaluation and biopsy in immunocompromised patients with esophagitis. CMV and HSV-1 coinfection, while rare, should be considered in this population due to its association with severe complications such as perforation and bleeding. Timely antiviral therapy and immunosuppression adjustment are critical for favorable outcomes.

Long-term follow-up of children with Crohn's disease and small bowel mucosal lesions detected through video capsule endoscopy.

We report disease outcomes of pediatric Crohn's disease (CD) affecting the proximal small bowel (SB) and detected through video capsule endoscopy (VCE). We undertook a retrospective review of CD patients with VCE performed under age 18 between 2003 and 2017 and having received any biologics. We identified patients from our institutional registry. Eligible patients (n = 118) had their first VCE performed after a median of 0.1 years after diagnostic endoscopies at a median age of 12.2 years. The proximal SB disease group (Paris classification L4b inclusive) comprised 70 patients with extensive SB lesions in 81% and deep ulcers in 79%. Patients with Paris L1-3 disease with no findings in VCE or disease restricted to the terminal ileum comprised the control group. At first VCE, levels of albumin (34 g/L vs. 37 g/L) and hemoglobin (117 g/L vs. 127 g/L) were lower in SB patients (p < 0.02). After the first VCE, 68% were introduced to biologics, while 10% already received them. Follow-up VCE was performed after a median of 2.4 years (SB group n = 42; controls n = 21). Proximal SB findings had disappeared in 40% of SB patients, and extensive lesions and deep ulcers had decreased to 26% and 29%, respectively (p = 0.001). In the control group, one had progressed to proximal disease. During the clinical follow-up of a median of 4.7 years, one patient with SB underwent surgery for a jejunal stricture. Proximal SB disease detected through capsule endoscopy abated in most patients with biological medication.

Sterile pyogranuloma/granuloma syndrome in two dogs presenting with extensive ulceration and systemic illness

AbstractThis report describes two cases of canine sterile pyogranuloma/granuloma syndrome presenting with fulminant extensive ulcerations, pyrexia and systemic malaise; one case with concurrent unilateral uveitis. This presentation contrasts to typically reported cases, and due to the severity of signs, urgent distinction from aggressive infectious causes was required. Both cases required extended immunosuppressive treatments for resolution.

PRP improves the outcomes of autologous skin graft transplantation on the esophagus by promoting angiogenesis and inhibiting fibrosis and inflammation.

Autologous skin graft (ASG) transplantation is a challenging approach but a promising option for patients to prevent postoperative esophageal stricture. Nonetheless, the current strategies require improvement. We aimed to investigate the effectiveness of the injection of platelet-rich plasma (PRP) before skin graft transplantation for extensive esophageal defects after endoscopic resection. Standardized complete circular endoscopic resection (5 cm in length) was performed in 27 pigs allocated into 3 groups. The artificial ulcers were treated with a fully covered esophageal stent (control group), ASG (ASG group), and submucosal injection of PRP with ASG (PRP-ASG group). Macroscopic evaluation and histological analysis of the remolded esophagus were performed 7, 14, and 28 days after surgery. The macroscopic evaluation indicated that submucosal injection of PRP before transplantation effectively promoted the survival rate of skin grafts and decreased the rate of mucosal contraction compared with those treated with ASG or stent alone. Histological analysis of submucosal tissue showed that this modified strategy significantly promoted wound healing of reconstructed tissues by enhancing angiogenesis, facilitating collagen deposition, and decreasing inflammation and fibrogenesis. These findings suggested that PRP might be used as a biological supplement to increase the esophageal skin graft survival rate and improve submucosal tissue remolding in a clinically relevant porcine model. With extremely low mucosal contraction, this novel combination strategy showed the potential to effectively prevent stenosis in extensive esophageal ulcers.

Vibrio ponticus and Vibrio harveyi infection in snubnose pompano, Trachinotus blochii, from marine aquarium

Vibriosis in a mixed community with Vibrio harveyi and Vibrio ponticus in adult snubnose pompano, Trachinotus blochii, is documented from a marine aquarium. The disease was clinically manifested by reduced feeding activity, lethargy, abnormal swimming behaviour, extensive and focal superficial ulceration in dorsal region, and mild opaque eye with haemorrhage. Histopathological examinations revealed moderate to severe epidermal necrosis and ulceration with scale pocket and dermal oedema. Scales were often displaced, distored or absent in skin sections. Cutaneous lesions were associated with a lymphocytic inflammatory infiltrate noted multifocally throughout the dermal layers. Grossly, the hepatopancreas had an area of pallor; on histological examination, the hepatopancreas displayed hepatocyte vacuolation and congestion.

Chronic osteoarthritis caused by Propionibacterium australiense infection in a captive sand gazelle.

Osteoarthritis is a common cause of morbidity and mortality in geriatric gazelles. Propionibacterium australiense has been reported as a cause of systemic granulomas in cattle, but there are no descriptions of this bacteria infecting other species nor causing osteoarthritis, to our knowledge. An 8-y-old, castrated male, sand gazelle (Gazella leptoceros leptoceros) was managed for chronic, intermittent, progressive osteoarthritis of the right tarsus. Serial biopsies revealed pyogranulomatous dermatitis with intralesional bacteria. Serial diagnostic imaging identified osseous and soft tissue proliferation with draining tracts. Treatments over 1 y included broad-spectrum antibiotics, anti-inflammatories, joint debridement, and infusion with platelet-rich plasma and stem cells. Despite therapy, lameness persisted, azotemia developed, and subsequently, the animal was euthanized. On postmortem examination, the periarticular tissue of the right tarsus was markedly expanded by pyogranulomas and fibrosis. Histologically, the synovium, joint capsule, and overlying soft tissues were markedly expanded by pyogranulomas and numerous gram-positive and acid-fast-negative filamentous bacteria surrounded by Splendore-Hoeppli material. Within the joint, there was regionally extensive cartilage ulceration, osteonecrosis, osteolysis, and pannus formation. PCR assay of affected formalin-fixed, paraffin-embedded tissue amplified segments of 16S rRNA and β subunit of bacterial RNA polymerase (rpoB) genes with 99.7% and 95.6% identity to P. australiense. This bacterium should be considered a differential for chronic pyogranulomatous osteoarthritis in gazelles.

Reconstructive Options for Pressure Ulcers in Pediatric Patients.

Pressure ulcers pose significant challenges in terms of treatment, often exhibiting a low success rate and a propensity for recurrence. Children with neurological impairments such as myelomeningocele and those with spinal injuries are particularly vulnerable to developing pressure ulcers. Despite advancements, achieving successful reconstruction remains a formidable task. Common sites prone to pressure ulcer formation include the sacral and ischial regions, as well as areas over bony prominences. Additionally, pressure ulcers attributable to medical devices facilitating ambulation are observed. While many pressure sores resolve spontaneously, conservative management may prove ineffective for some, especially in cases of stage 3 and 4 ulcers, necessitating surgical intervention. Various surgical techniques are employed for the treatment of decubitus ulcers, yet there exists no universally accepted gold standard for their management. This paper presents our institutional experience in this domain, highlighting differences in surgical approaches, treatment outcomes, complication rates, and long-term follow-up. This study involved a retrospective analysis of medical records from 11 children, ranging in age from 10 to 17 years, who presented with extensive pressure ulcers that were unresponsive to conservative treatment measures. Data collection spanned from February 2017 to June 2022. The pressure ulcers affected various anatomical regions, including the ischial area (5/11 patients), sacral region (3/11 patients), lower limb (1/11 patients), elbow (1/11 patients), and perineal area (1/11 patients). Surgical intervention was the chosen approach for all cases, employing techniques such as reconstructive surgery utilizing perforator, pediculated flaps, and locoregional flaps. Eleven patients with sore ulcers (stage 3 and 4) were treated surgically. We present our experience of using surgical methods, including pedicled anterolateral flaps, pedicled gracilis musculocutaneous flaps, propeller flaps and locoregional flaps. In some cases, surgery was performed after 60 days of hospitalization or ten years after ulcer occurrence. We reviewed the length of hospital stay, surgical management and patient satisfaction. Patients were followed up to 5 years post-surgery. All flaps survived except for one flap where partial necrosis was observed. The recurrence rate was 9.01% (1/11). One patient underwent another surgery. The general outcome was satisfactory. Conclusions: Our findings underscore the efficacy of flap reconstruction surgical techniques in the management of pressure ulcers among pediatric patients. Based on our experience and the outcomes observed, we advocate for considering reconstructive surgery as a viable therapeutic option early in the treatment course, particularly for stage 3 and 4 ulcers. This approach not only addresses the immediate needs of patients but also holds promise for long-term wound healing and prevention of recurrence.

From the experience of more than 1000 glue ablation procedures for varicose veins: how to do it

Cyanoacrylate adhesive closure (CAC) is currently one of the main non-thermal ablation modalities of incompetent saphenous veins. High efficacy and safety of the method is supported by international clinical practice guidelines as well as the real-world practice. In contrast to thermal ablation, CAC is advantageous in terms of low periprocedural pain and bruising, fast procedure time and postprocedural recovery, high patient comfort and satisfaction rates as well as avoidance of postprocedural compression. This publication summarises the practical tips and tricks of glue ablation procedure based on 5-year experience (2019–2023) at the “SM-Clinic” Phlebology Centre, Moscow. Indications for the preferred use of CAC are formulated, such as: low pain threshold; contraindications (or unwillingness) to postprocedural compression; extensive comorbidity and fragile patients; concomitant morbid obesity; the presence of axial reflux along the saphenous veins; the need for simultaneous ablation of several incompetent truncal veins; below-the-knee incompetence of saphenous veins, including recurrent varicose veins; extensive lipodermatosclerosis and/or venous leg ulcer; patient’s HIV and viral hepatitis positive status. A step-by-step interventional protocol of glue ablation is described, including the modified protocols of the procedure. The immediate and long-term outcomes of the CAC according to current data are discussed. Special attention is paid to adverse events following CAC, as well as technical aspects of their prevention. Despite high efficacy and safety profile, today’s limitations for adoption and wider use of CAC are cost issues and lack of reimbursement.

Ulcerative stomatitis associated with yellow bristle grass in New Zealand dairy cows

ABSTRACT Case history A line of 25 cull cows were all found to have ulcerative lesions of the tongue at post-mortem inspection in a New Zealand slaughter plant. A further 9 of 10 cows inspected at the farm of origin had similar oral lesions. There were no other clinical signs or indicators of ill-health observed at ante-mortem inspection in the abattoir or on the farm. The cows had been fed baleage for 3 weeks prior to slaughter, made from pasture in paddocks heavily contaminated with yellow bristle grass (Setaria pumila). Clinical findings There was extensive and deep transverse linear ulceration in the lingual fossa immediately rostral to the torus linguae. At histological examination, full-thickness ulceration of the stratified squamous epithelium was observed with a bed of disorganised collagenous tissue and extensive mixed inflammatory infiltrate extending into the sub-epithelial connective tissue and skeletal muscle. Barbed plant fragments were embedded in both the superficial and deeper areas of inflammation. Detailed examination of the baleage also found that yellow bristle grass seedheads were present. Diagnosis Based on the presence of barbed plant material in the tongue and yellow bristle grass seeds in the baleage, a diagnosis of ulcerative stomatitis associated with yellow bristle grass was made. Clinical relevance Clinicians should be aware of the potential for hay or baleage contaminated with yellow bristle grass to cause oral lesions in cattle.

Abstract PO5-26-01: Assessing the effect of multimodal therapy in massive fungating breast cancers without distant metastasis

Abstract Background: Massive fungating breast cancers (MFBCs), which comprise exudative, foul-smelling tumors, the size of a child’s head or involve extensive ulceration are classified as locally advanced breast cancers. The National Comprehensive Cancer Network guidelines recommend preoperative neoadjuvant chemotherapy in patients with locally advanced breast cancer without distant metastases. However, limited evidence is available regarding the successful treatment of fungating breast cancers. In clinical practice, many fungating breast cancer cases are treated as stage IV tumors. This study aimed to investigate whether multimodal therapy, including surgery for giant breast cancers, can improve survival rates and whether the survival rates are comparable to those of other stage III breast cancers. Subjects and methods: Out of 1480 cases of primary breast cancer diagnosed at our hospital between June 2012 and March 2020, 123 patients with clinical stages IIIA–IIIC were chosen for analysis. Furthermore, 29 of these patients with MFBC were selected. During multimodal therapy for selected patients with fungating breast cancer, difficulties were encountered in some patients with single-stage skin suturing and closure after standard neoadjuvant chemotherapy. These patients underwent surgery with an additional skin flap or skin grafting. Furthermore, radiation therapy was added as needed. We compared the survival rates of these patients with those of patients who received drug therapy only according to the therapeutic protocol for Stage IV. Survival rates of patients with MFBC and other stage III breast cancers were also compared. Statistical analyses were conducted using the Kaplan–Meier curve and the log-rank test. Results: Of the 29 patients with MFBC, 22 (75.9%) and seven (24.1%) were treated with multimodal and palliative therapies, respectively. The median age and follow-up period of the multimodal therapy group were 62 (range: 43–94) years and 67 (range, 32–131) months, respectively. The corresponding values for the palliative therapy group were 79 (range: 42–88) years and 31 (range: 2–96) months. All patients in the palliative treatment group were hormone receptor positive and HER2 negative, and treatment with hormone therapy was initiated. The 7-year survival rate was significantly higher in the multimodal therapy group than in the palliative treatment group (92.3% vs. 68.6%, p = 0.0317). Furthermore, the 5-year distant recurrence-free rate was higher in the multimodal treatment group (79.3% vs. 63.5%). Local recurrence did not occur in any patient in the multimodal treatment group. There was no significant difference in the 7-year survival rates between patients with MFBC and those with other stage III breast cancers (86.8% vs. 75.3%; p = 0.239). Triple-negative breast cancer accounted for 20.8% (20 96) of the other stage III breast cancers, but none of these were MFBCs. Conclusions: Clinically, MFBCs are often palliatively treated as stage IV tumors, even in the absence of distant metastasis. However, the survival rate was significantly higher in the multimodal therapy group than in the palliative treatment group. Furthermore, the survival and distant recurrence-free rates for MFBC were higher than those for other stage III breast cancers. Therefore, patients with MFBCs should be actively treated using curative treatments.
