BACKGROUND: Pyoderma gangrenosum (PG) is a rare, difficult-to-treat neutrophilic ulcerative cutaneous condition that severely impacts those affected. Treatment options for PG are limited, and disease remission is not guaranteed. Hyperbaric oxygen treatment is a potential therapeutic option for treating various ulcerative conditions not frequently utilized for PG.
METHODS: We present a case of a patient with treatment-resistant PG who achieved remission with adjunctive HBOT, and then later had difficulty achieving remission without HBOT during a future flare.
CONCLUSIONS: HBOT should be more readily considered as a treatment option for those with PG.

Infected skin ulcers represent a frequent and intricate clinical challenge, necessitating prompt and comprehensive multidisciplinary interventions to avert complications. Anti-infective therapy constitutes a cornerstone in the therapeutic paradigm. This manuscript delineates our approach to anti-infective management of infected ulcers, encompassing insights into clinical classifications, diagnostic features, exampless of early clinical decision-making in anti-infective treatment, comprehensive evaluation of infectious diseases encompassing host clinical considerations and potential interventions, determination of antibiotic therapy duration, methodologies for assessing clinical response, identification of potential causes for lack of clinical response, as well as strategies for outpatient parenteral antibiotic therapy and a diagnostic and therapeutic algorithm.

OBJECTIVE: To compare the recently proposed Capsule Endoscopy-Crohn\'s Disease index (CE-CD) to pre-existing capsule endoscopy (CE) scores, to measure its precision and accuracy to predict adverse clinical outcomes in children with Crohn\'s disease (CD).
METHODS: Children with CD who underwent CE at diagnosis and had, at least, 1-year follow-up postprocedure were selected. Capsule study was viewed and the different indices were independently scored by two trained paediatric gastroenterologists. The relationship between pre-existing scores and CE-CD was assessed by linear regression analysis. Clinical outcomes prediction assessment was based on receiver operating characteristics curves, survival analysis and Cox regression. Finally, interobserver agreement was measured.
RESULTS: Fifty-nine patients were finally included. CE-CD showed a strong positive correlation with the Lewis score (ρ = 0.947) and the Capsule Endoscopy Crohn\'s Disease Activity Index (CECDAI) (ρ = 0.982). Both CE-CD and CECDAI were significant predictors of treatment escalation (hazard ratio 1.07 and 1.09, respectively, with both p-values < 0.01). However, no score predicted risk of hospital admission, surgery or clinical/endoscopic relapse. The presence of moderate-to-severe small bowel (SB) inflammation, defined as a score of ≥9 on CE-CD, provided a hazard ratio of treatment escalation of 2.6 (95% confidence interval: 1.3-5.3). This cut-off provided the optimal sensitivity/specificity pair: 48.4%/89.3%. No interobserver misclassification among inflammation categories given by CE-CD were observed (kappa 100%).
CONCLUSIONS: CE-CD is a useful tool to document SB inflammation in children with CD. It correlates strongly with classical scores, can better predict need for treatment escalation and shows good interobserver agreement.

BACKGROUND: The presence of a wound can be anywhere from non-problematic to life-threatening on a severity spectrum, with bacterial infection and resistance playing a major role in the development of chronicity, delaying wound healing. Wound colonization with multiple organisms and the limited number of effective antibiotics place a heavy burden on the healthcare system, with patients going through multiple surgeries during a prolonged hospitalization time. By analyzing the resistance patterns of pluri-bacterial populations and the approach used in managing complex cases, we aim to improve the protocols applied in caring for chronic wounds in our practice and share our experiences and observations.
METHODS: We designed a retrospective study on 212 diabetic and non-diabetic patients, aiming to evaluate the course of chronic wound treatment in our practice. We focused on the impact that MDR bacteria and diabetes have on surgical outcomes and their role in the healing process.
RESULTS: Patients who received empiric antibiotic therapy before being admitted eventually presented with multiple MDR bacteria compared to those who did not receive antibiotics (p = 0.014). The presence of at least one MDR bacteria in the wound bed was associated with ulcers reaching bone (p = 0.02) and was positively correlated with the number of surgeries performed (p < 0.001). Diabetes played a significant role in surgery-related complications (p = 0.02) and hospitalization time (p < 0.001).
CONCLUSIONS: Proper management of chronic wounds requires a comprehensive, multidisciplinary approach and a thorough understanding of antibiotic usage. To address this need, we have developed and implemented a chronic wound treatment protocol in our clinic, with the goal of discharging patients once their ulcers have been treated and closed. A key summary of the protocol presented is to reduce the incidence of MDR bacteria and improve the patient\'s quality of life.

Antiphospholipid syndrome (APS) is an autoimmune disorder characterized by recurrent arterial and venous thrombosis, habitual fetal miscarriages, often accompanied by mild to moderate thrombocytopenia, and persistent moderate-to-high titer positivity for antiphospholipid antibodies (aPLs). However, patients with antiphospholipid antibodies may also present with several nonthrombotic clinical manifestations, such as thrombocytopenia, cardiac valve disease, nephropathy, skin ulcers, or cognitive dysfunction, which are collectively referred to as nonstandard manifestations of APS. Of these, for APS with predominantly cutaneous ulcers, previous reports have focused on APS with combined cutaneous vasculitis, and its medical treatment, rather than cutaneous ulcers with predominantly fatty inflammatory lesions, and the associated surgical treatment. Here, we admitted a relatively rare case of primary APS with extensive skin ulceration of the right lower extremity, without cutaneous vasculitis, in the presence of extensive and severe inflammatory lipoatrophy, carrying anti-β2-glycoprotein I and lupus anticoagulant, which is reported as follows, with a view to raising awareness of this disease.

BACKGROUND: Trigeminal trophic syndrome (TTS) is a rare condition caused by damage to the trigeminal nervous system, resulting in sensory disturbances and ulcers on the face. Treating TTS is complex and often requires medical or surgical intervention like flap reconstruction. However, there is limited research on surgical treatments for TTS ulcers.
METHODS: We report the case of a 19-year-old man with TTS. We employed an innovative surgical technique involving dual cross-face nerve grafts. In the initial procedure, corneal neuralization was accomplished using supraorbital and cross-face infraorbital nerve graft. The subsequent operation utilized auricular composite tissue flap transplantation repair and cross-face mental nerve graft.
RESULTS: This procedure led to rapid and sustained healing, as well as aesthetic improvement.
CONCLUSIONS: Cross-face nerve grafts is a promising tool in the treatment of refractory ulcers caused by diseases such as TTS.

BACKGROUND: Ankylosing spondylitis (AS) and Behçet\'s disease (BD) are distinct inflammatory disorders, but their coexistence is a rare clinical entity. This case sheds light on managing this complex scenario with Janus kinase (JAK) inhibitors.
METHODS: A 42-year-old woman presented with a decade-long history of lower back pain, nocturnal spinal discomfort, recurrent eye issues, oral and genital ulcers, hearing loss, pus formation in the left eye, and abdominal pain. Multidisciplinary consultations and diagnostic tests confirmed AS (HLA-B27 positivity and sacroiliitis) and BD (HLA-B51). Elevated acute-phase markers were observed.
CONCLUSIONS: This case fulfills diagnostic criteria for both AS and BD, emphasizing their coexistence. Notably, treatment with upadacitinib exhibited promising efficacy, underscoring its potential as a therapeutic option in patients with contraindications for conventional treatments. Our findings illuminate the intricate management of patients presenting with these two diverse systemic conditions and advocate for further exploration of JAK inhibitors in similar cases.

UNASSIGNED: Wound healing is severely compromised in patients with diabetes owing to factors such poor blood circulation, delayed immune response, elevated blood sugar levels, and neuropathy. Although the development of new wound healing products and prevention of serious complications such as infections in wounds have received substantial interest, wound healing remains a challenge in regenerative medicine. Burn wounds, especially third-degree burns, are difficult to treat because they are associated with immune and inflammatory reactions and distributive shock. Wound care and treatment that protects the burn site from infection and allows wound healing can be achieved with bioengineered wound dressings. However, few studies have reported effective dressings for third-degree burn wounds, making it important to develop new dressing materials.
UNASSIGNED: In this study, we developed an artificial amniotic membrane (AM) using epithelial and mesenchymal cells derived from human amnion as a novel dressing material. The artificial AM was applied to the wound of a diabetic third-degree burn model and its wound healing ability was evaluated.
UNASSIGNED: This artificial amnion produced multiple growth factors associated with angiogenesis, fibroblast proliferation, and anti-inflammation. In addition, angiogenesis and granulation tissue formation were promoted in the artificial AM-treated mouse group compared with the control group. Furthermore, the inflammatory phase was prolonged in the control group.
UNASSIGNED: Our preliminary results indicate that the artificial AM might be useful as a new dressing for refractory ulcers and third-degree burns. This artificial AM-based material represents great potential for downstream clinical research and treatment of diabetes patients with third-degree burns.
