BACKGROUND
Different fibula osteocutaneous free flap (FOCFF) configurations have been described with a double-skin paddle (DSP) to address composite through-and-through oromandibular defects: division of the skin paddle using different perforators (div-FOCFF) or a de-epithelialized DSP FOCFF (deEpi-FOCFF). This study aimed to compare the surgical outcomes using these two methods (deEpi-FOCFF/div-FOCFF).
METHODS
Patients who underwent segmental mandibulectomy and reconstruction with a DSP FOCFF between 2011 and 2014 were included. We compared postoperative outcomes of patients undergoing reconstruction with deEpi-FOCFF versus div-FOCFF implementing propensity score matching.
RESULTS
Of the 245 patients, 156 cases (78 pairs) were 1:1 matched. Demographic and oncologic variables were comparable between groups. The average age was 57.68 years. A higher number of perforators per flap was evident in the div-FOCFF group (p < 0.001). The deEpi-FOCFF group exhibited a higher total flap loss rate when compared to the div-FOCFF group (15 % versus 5 % p = 0.03). On multivariate analysis, number of perforators per flap (OR 0.31, p = 0.02), using the deEpi-FOCFF (OR 3.88, p = 0.03), and an increased reconstructive time (OR 1.01, p = 0.01) independently affected the likelihood of free flap failure.
CONCLUSION
If the number and location of perforators are optimal, div-FOCFF improves reconstructive outcomes for composite oromandibular defects versus the deEpi-FOCFF.

INTRODUCTION
Colon volvulus is the twisting of a segment of colon on its mesenteric axis, which can lead to the obstruction of the lumen and the blood supply. Colon volvulus is common in "volvulus belt" countries and can involve the sigmoid (60-70%) and cecum (25-40%).
CASE PRESENTATION
We report a case of a 47-year-old male, Alawites, who presented with bowel obstruction and dilated abdomen without any specific abdominal pain. Abdominal laparotomy showed both sigmoid and cecum volvulus with no signs of perforation or ischemia.
DISCUSSION AND CONCLUSION
One of the possible risk factors of sigmoid colon volvulus is the length of the rectum and sigmoid, while mobile cecum is considered as a possible reason for cecum volvulus. The management remains controversial and is specific for every case, depending mainly on the vitality of the colonic walls and the general condition of the patient.

INTRODUCTION
The incidence of osteoporotic pelvic fractures is increasing. The broken anterior pelvic ring is preferentially fixed with long intramedullary screws, which require a good understanding of the patient-specific anatomy to prevent joint perforation. The aim of this study was to assess the variability of the superior pubic ramus and the supra acetabular corridors' length and width using statistical shape modelling.
MATERIALS AND METHODS
A male and female statistical shape model was made based on 59 forensic CT scans. For the superior pubic ramus and the supra acetabular corridor the longest and widest completely fitting cylinder was created for the first 5 principal components (PC) of both models, male and female pelvises separately.
RESULTS
A total of 59 pelvises were included in this study of which 36 male and 23 female. The first 5 principal components explained 75% and 79% of the pelvic variation in males and females, respectively. Within 3 PCs of the female statistical shape model (SSM) a superior pubic ramus corridor of < 7.3 mm was found, 5.5 mm being the narrowest linear corridor measured. Both corridors in all PCs of the male SSM measured > 7.3 mm.
CONCLUSION
Within females a 7.3 mm and 6.5 mm screw won't always fit in the superior pubic ramus corridor, especially if a flat sacrum, a small pelvis or a wide subpubic angle are present. The supra acetabular corridor did not seem to have sex-specific differences. In the supra-acetabular corridor there was always enough space to accommodate a 7.3 mm screw, both in males and females.

Introduction The role of endoscopic submucosal dissection (ESD) in the treatment of Barrett's associated neoplasia (BEN) has been evolving. We examined the efficacy and safety of ESD and EMR for BEN. Methods A database search was performed for studies reporting efficacy and safety outcomes of ESD and EMR for BEN. Pooled proportional and comparative meta-analyses were performed. Results 47 studies (23 ESD, 19 EMR, and 5 comparative) were included. Mean lesion size for ESD and EMR were 22.5 mm and 15.8 mm respectively. Majority of lesions were Paris type IIa. Pooled analysis for ESD showed en-bloc resection, R0 resection, curative resection, and local recurrence rates of 98%, 78%, 65%, and 2%, respectively. Complete eradication of dysplasia (CE-D) and complete eradication of intestinal metaplasia (CE-IM) were achieved in 94% and 59% of cases. Pooled rates of perforation, intraprocedural bleeding (IPB), delayed bleeding (DB), and stricture were 1%, 1%, 2%, and 10%, respectively. Pooled analysis for EMR showed en-bloc resection, R0 resection, curative resection, and local recurrence rates of 37%, 67%, 62%, and 6%, respectively. CE-D and CE-IM were achieved in 94% and 76% of cases. Pooled rates of perforation, IPB, DB, and stricture were 0.1%, 1%, 0.4%, and 7.7%, respectively. The mean procedure time for ESD and EMR were 111.3 and 22.3 mins respectively. Comparative analysis showed higher en-bloc and R0 resection rates with ESD compared to EMR, with comparable adverse events. Conclusion ESD and EMR both can be employed to treat BEN depending on the lesion type, size, and expertise.

Systemic lupus erythematosus (SLE) is a complex autoimmune disease where the body loses tolerance to its own antigens, particularly nuclear antigens. Abnormal responses from T and B cells lead to the production of autoantibodies and the formation of immune complexes in tissues, triggering complement activation, inflammation, and irreversible organ damage. SLE can affect any part of the body, resulting in diverse clinical symptoms. One rare manifestation of SLE is lupus mesenteric vasculitis (LMV), which presents with vague symptoms, abnormal laboratory findings, and specific imaging features. LMV, although uncommon, can progress to severe complications such as bowel perforation, haemorrhage, and even mortality. Here, we report a case of LMV with the involvement of multiple organ systems (including mucocutaneous, musculoskeletal, serosal cavities, and haematological systems), presenting initially with life-threatening intractable gastrointestinal bleeding, and complicated by severe pulmonary infection. By sharing this case, we aim to enhance clinicians' confidence in managing critical SLE cases and raise awareness about disease surveillance.

Emergency surgeries are linked with increased morbidity and reduced life expectancy, often associated with low socioeconomic status, limited access to healthcare, and delayed hospital admissions. While the influence of socioeconomic status on elective surgery outcomes is well-established, its impact on emergency surgeries, including ostomy creation and closure, is less clear. This study aimed to explore how the pandemic and socioeconomic status affect emergency ostomy procedures, seeking to determine which has a greater effect. It emphasizes the importance of considering socioeconomic factors in patient care pathways for ostomy procedures. A total of 542 patients who underwent emergency ostomy formation between 2016 and 2022 were retrospectively analyzed and divided into pre-pandemic and pandemic periods. The pre-pandemic and pandemic periods were compared between themselves and against each other. Demographic data (age and sex), comorbidities, socioeconomic status, etiology of the primary disease, type of surgery, stoma type, length of hospital stay, ostomy closure time, and postoperative complications were retrospectively analyzed for all patients. In total, 290 (53%) patients underwent surgery during the pandemic period, whereas 252 (47%) underwent surgery during the pre-pandemic period. Emergency surgery was performed for malignancy in 366 (67%) patients. The number of days patients underwent ostomy closure was significantly higher in the low-income group (P = .038, 95% CI: 293,2, 386-945). The risk of failure of stoma closure was 3-fold (95% CI: 1.8-5.2) in patients with metastasis. The risk of mortality was 12.4-fold (95% CI: 6.5-23.7) when there was failure of stoma closure. When compared to pandemic period, the mortality risk was 6.3-fold (95% CI: 3.9-10.2) in pre-pandemic period. Pandemic patients had a shorter hospital stay than before the pandemic (P = .044). A high socioeconomic status was significantly associated with early hospital admission for ostomy closure, and lower probability of mortality. More metastases and perforations were observed during the pandemic period and mortality was increased during pandemic and in patients without ostomy closure. The socioeconomic status lost its effect in cases of emergency ostomy creation and had no impact on length of hospital stay in either the pre-pandemic or pandemic period.

The free radical and cytokine statuses of the cornea during its thermal burn and the possibility of its correction by lactoferrin have been studied in Soviet Chinchilla rabbits. The development of a corneal thermal burn was accompanied by the development of oxidative stress (increased levels of TBA-reactive substances and carbonyl derivatives of proteins, decreased activity of SOD and GPx enzymes) and a pronounced inflammatory reaction with increased levels of TNF-1α, IL-10, TGF-1β. The use of lactoferrin had a pronounced therapeutic effect, which was manifested by accelerated healing, prevention of the development of complications (corneal perforations), a decrease in the severity of oxidative stress, an increase in the concentrations of TNF-1α (in the early stages), IL-10 (in the later stages), TGF-1β (throughout the experiment). At the same time, by the end of regeneration more severe corneal opacification was recognized compared to the control group. This may be associated with an increased level of anti-inflammatory cytokines, especially TGF-1β.

BACKGROUND
Cocaine is the second most consumed drug worldwide, more than 0.4% of the global population, and has become a real public health problem in recent years. Its inhalation causes significant centrofacial lesions, grouped under the name cocaine-induced midline destructive lesion (CIMDL). These destructions are due to the conjunction of the vasoconstrictor, local prothrombogenic effects, and cytotoxic effects of cocaine. The ischemia produced by this substance is due to vasoconstriction that leads to nasal tissue necrosis and perforation of the nasal septum secondary to chondral necrosis. . A 36-year-old man, previously grappling with cocaine addiction, was hospitalized to undergo comprehensive clinical, microbiological, and radiological examinations because he was suffering from the emergence of crusts and ulceration in the nasal mucosa, accompanied by a palate perforation, a 39°C fever, and chills. Standard bacteriological culture was positive for coagulase-negative staphylococci and , while mycological culture was positive for . The CT scan images of the sinuses confirmed the presence of palatal perforation and total destruction of the nasal septum, cartilaginous portion, maxillary sinus medial wall, lower and middle turbinates, and middle meatus. Nasal endoscopy revealed an exposition of the bony wall and displayed the exposition of the occipital bone's clivus. A diagnosis of CIMDL was confirmed. Antibiotic therapy was decided based on antibiogram results by the consulting microbiologist. Debridement of necrotic tissue was done by nasal endoscopy with local cleaning and was repetitive during the first week to maintain the best cleanliness possible. The patient was discharged with oro-nasal hygiene instructions and referred for prosthetic rehabilation. As for the cocaine addiction, the patient was in follow-up with a psychologist in a specialized centre.
CONCLUSION
The care is multidisciplinary. Psychological help and assistance are essential to guide patients to become cocaine free and to avoid a relapse. Weaning is a prerequisite for surgery. Rehabilitation of speech and swallowing is necessary. Many local flaps or micro-anastomoses are possible.

Acquired reactive perforating collagenosis is a rare cutaneous disorder characterised by the extrusion of abnormal connective tissue trough epidermidis and/or follicular units. Reactive perforating collagenosis is often associated with systemic diseases in which pruritus is a common symptom (e.g., diabetes and chronic kidney disease). Less commonly, it has been associated with chronic inflammatory dermatoses, including atopic dermatitis, as in this case. In this report, we describe the exceptional case of a 35-year-old man affected by acquired reactive perforating collagenosis associated with atopic dermatitis who was resistant to conventional topical and systemic treatment and experienced complete resolution of clinical signs and symptoms after 12 weeks of treatment with dupilumab. In our patient, the severe pruritus induced by atopic dermatitis likely contributed to the development of acquired perforating collagenosis lesions, which are thought to be a reactive response to chronic scratching and repetitive injury to the skin. Chronic pruritus in atopic dermatitis is known to be driven by type 2 cytokines, including IL-4 and IL-13, and dupilumab, a monoclonal antibody inhibiting IL-4 and IL-13 signalling, has been shown to be effective in the treatment of moderate to severe atopic dermatitis as well as other type 2-driven pruritic dermatological conditions. This case supports the potential use of dupilumab for the treatment of reactive perforating dermatosis.

BACKGROUND
Minimally invasive beaded electrosurgical dissectors ("BEED devices") provide simultaneous sharp dissection, blunt dissection, and electrosurgical coagulation while performing 100 cm porcine tissue plane dissections in 0.8 to 3 min with minimal bleeding and no perforations.
OBJECTIVES
The aim of the study was to report the basic science and potential clinical applications and to video document the speed and quality of planar dissections in in vivo and ex vivo porcine models with thermal damage quantified by thermal and histopathologic measurements. Additionally, in vivo porcine specimens were followed for 90 days to show whether adverse events occurred on a gross or macroscopic basis, as evidenced by photography, videography, physical examination, and dual ultrasonography.
METHODS
Ex vivo porcine models were subjected to 20, 30, and 50 W in single-stroke passages with BEED dissectors (granted FDA 510(k) clearance (K233002)) with multichannel thermocouple, 3 s delay recordation combined with matching hematoxylin and eosin (H&E) histopathology. In vivo porcine models were subjected to eight 10 × 10 cm dissections in each of 2 subjects at 20, 30, and 50 W and evaluated periodically until 90 days, wherein histopathology for H&E, collagen, and elastin was taken plus standard and Doppler ultrasounds prior to euthanasia.
RESULTS
Five to 8 mm width dissectors were passed at 1 to 2 cm/s in ex vivo models (1-10 cm/s in vivo models) with an average temperature rise of 5°C at 50 W. Clinically evidenced seromas occurred in the undressed, unprotected wounds, and resolved well prior to 90 days, as documented by ultrasounds and histopathology.
CONCLUSIONS
In vivo and ex vivo models demonstrated thermal values that were below levels known to damage subcutaneous adipose tissue or skin. Tissue histopathology confirmed healing parameters while Doppler ultrasound demonstrated normal blood flow in posttreatment tissues.
