The Role of Vitamin C in Wound Healing in Surgically Managed Diabetic Foot Disease

Background: Diabetic foot ulcers (DFUs) represent a significant cause of morbidity in diabetic patients, with surgical management frequently required in advanced cases. This study examines the association between preoperative vitamin C levels and wound-healing outcomes in patients with diabetic foot disease (DFD) requiring surgical debridement. Methods: A retrospective cohort study was conducted at a tertiary referral centre, with the study including diabetic patients who had undergone surgical debridement for forefoot and midfoot diabetic foot infections between January 2020 and July 2024. Patients with ISDA grades 3 and 4 ulcers and preoperative measurements of vitamin C, albumin, HbA1c, and BMI were included. The primary outcome was time to wound healing, defined as the duration from surgery to discharge from the orthopaedic diabetic foot clinic. Data were analysed using generalized linear models to assess the impact of preoperative vitamin C levels on healing time, controlling for confounding variables. Results: In the 61 patients included in the multivariable regression analysis, higher preoperative vitamin C levels were significantly associated with faster wound healing (p = 0.01). Other significant factors included albumin levels and ulcer location, with midfoot ulcers healing more slowly than forefoot ulcers. The mean time to healing was 3 months, with vitamin C levels showing a statistically significant effect on wound-healing outcomes. Conclusions: Our study demonstrates that higher preoperative vitamin C levels were associated with faster wound healing in surgically treated diabetic foot ulcers. Future prospective randomized controlled trials are needed to confirm these findings and assess the role of vitamin C supplementation in the management of surgically treated DFUs.

Dogs receiving cyclooxygenase-2-sparing nonsteroidal anti-inflammatory drugs and/or nonphysiologic steroids are at risk of severe gastrointestinal ulceration.

To report the incidence and characteristics of gastrointestinal ulceration lesions in dogs receiving an NSAID and/or corticosteroid. 33 dogs. Medical records of dogs with gastrointestinal ulceration receiving NSAIDs and/or corticosteroids within 30 days of diagnosis between January 2012 and July 2022 at multiple referral institutions were reviewed. Diagnosis was confirmed via endoscopy, surgery, or necropsy. Clinical data were collected from the medical record, including the dose and reason for administration of NSAIDs or steroids. Dogs received a single NSAID (n = 22, most commonly carprofen [9], meloxicam [4], and deracoxib [3]), 2 NSAIDs (5), a single steroid (5: prednisolone [2], prednisone [2], or dexamethasone SP [1]), or an NSAID and steroid (1). Eleven dogs receiving a single cyclooxygenase (COX)-2-sparing NSAID at an appropriate dose had ulcerations. All dogs receiving 2 NSAIDs concurrently experienced full-thickness perforation (5 of 5). The most common ulcer locations were duodenum (n = 18) and pylorus (11). Abdominal ultrasound correctly identified the site of ulceration in 5 of 24 dogs. Dogs receiving COX-2 sparing NSAIDs at recommended doses are at risk of severe GI ulceration. Carprofen was the most common NSAID resulting in ulceration; however, it is one of the most prescribed NSAIDs. Adding another NSAID and steroid could increase this risk. Careful monitoring is crucial for dogs on NSAIDs, regardless of duration.

Digital ulcers in systemic sclerosis are strongly associated with digital arterial disease: a finger-by-finger analysis of Finger Brachial Pressure Index Measurements.

The digital ulcers of systemic sclerosis are disabling and frequent· Their pathogenesis involves a capillary microangiopathy and a digital arterial disease that few studies were able to quantify up to now. A multicentre observational study about the predictive value of capillaroscopy in systemic sclerosis offered us the opportunity to evaluate further the complementary information provided by both capillary and arterial evaluations. During the SCLEROCAP study, five out of the nine centers performed a systematic evaluation of the finger brachial pressure index (FBPI) in the last four fingers of both hands at baseline, using the same laser-doppler device. In the present work, FBPI measurements were compared between fingers with vs without digital ulcers or scars, before and after adjusting for the capillaroscopic pattern and systemic factors. FBPI measurements were performed in 2537 fingers from 326 patients. Active ulcers or scars were found in 10·8% of those fingers, more often on the right hand, and in the second and third fingers. FBPI was lower than 0·70 in 26% of all fingers and in 57·5% of those with ulcers. A strong association was found between a low FBPI and the presence of digital ulcers, even after adjusting for capillaroscopic pattern, ulcer location and the patient himself. These results confirm the importance of digital arterial disease in the pathogenesis of digital ulcers of systemic sclerosis, which is independent from the microangiopathy. FBPI measurements complement the information provided by capillaroscopy and might have an important predictive value for subsequent digital ulcers.

Analyzing Recurrence Rates in Pyoderma Gangrenosum

Pyoderma Gangrenosum (PG) is a rare skin disease characterized by rapid development of painful skin ulcers with violaceous borders that is often associated with inflammatory disorders.1,2 Treatment involves systemic immunosuppression alongside wound care management.2,3 Despite clinicians’ best efforts in implementing appropriate therapy, PG ulcers can recur, and there is minimal data regarding recurrence rates. We systematically reviewed Embase, MEDLINE, and Cochrane library for cases, case series, and clinical studies of confirmed PG to evaluate for recurrence rates. Recurrence was defined as the appearance of new ulcerations after complete initial healing. Our analysis found 269 studies with 351 patients. Among this cohort, 34 cases (10%) described one or more recurrence episodes. Within these 34 cases, ulcer locations were as follows: 20 (56%) on the lower extremities, 12 (33%) on the trunk, 1 (3%) on the upper extremities, 1 (3%) on the head, and 2 (5%) in unspecified areas. When analyzing the time of recurrence from initial healing, we found that 11 cases (29%) recurred in 3 months or less, 5 (14%) from 3 to 6 months, 1 (3%) from 6 to 12 months, and 7 (19%) after 12 months. 13 cases (35%) did not specify a timeline for recurrence, and 3 cases reported two recurrence episodes. In conclusion, our study investigates PG recurrence patterns and suggests that about 10% of patients with PG might experience recurrence after healing, which supports previously reported data.4 Future directions include the impact of treatment duration and treatment type (topical versus systemic) on recurrence rates.

Transcatheter embolization for duodenal ulcer bleeding originating from cystic artery erosion

BackgroundUlcer erosion into the cystic artery is a rare cause of bleeding in duodenal ulcers, with only a limited number of cases described in the literature. Historically, treatment has predominantly involved surgical intervention. We present three cases of duodenal ulcer bleeding due to cystic artery erosion, which were successfully managed with cystic artery embolization.Case presentationThis case series includes three male patients with duodenal ulcer bleeding, aged 90, 81, and 82 years, respectively, and no prior history of biliary system disorders. The ulcer locations were identified as two in the post-bulbar region and one in the anterior bulb. After the failure of medical and endoscopic treatment, transcatheter arterial embolization was adopted. Initial angiography did not reveal any contrast medium extravasation. Empirical embolization of the gastroduodenal artery using gelatin sponge particles and coils failed to achieve hemostasis. Super-selective cystic artery angiography confirmed the source of bleeding as the cystic artery. One patient was embolized with gelatin sponge particles and coils, while the other two patients were embolized with N-butyl-cyanoacrylate. All patients achieved successful hemostasis without gallbladder infraction.ConclusionsCystic artery embolization proved to be a minimally invasive technique for achieving hemostasis in these cases, indicating that it may be a safe and effective alternative to surgery for this uncommon cause of upper gastrointestinal bleeding. Validation through further studies is warranted.

PREVALENCE, SURGICAL MANAGEMENT, AND OUTCOME OF PERFORATION OF THE GASTER ASSOCIATED WITH LONG TERM CORTICOSTEROID USE : A COMPREHENSIVE SYSTEMATIC REVIEW

Background: In the general population, gastroduodenal perforation can occur as a complication of pre-existing peptic ulcer disease (PUD). In this scenario, the morbidity and mortality are already well documented. The lifetime risk of perforation is approximately 2–10 in cases of untreated PUD, and despite an improvement in resuscitation, and intensive and surgical care, the mortality rate remains around 25. The aim: The aim of this study to show about prevalence, surgical management, and outcome of perforation of the gaster associated with long term corticosteroid use. Methods: By the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) 2020, this study was able to show that it met all of the requirements. This search approach, publications that came out between 2014 and 2024 were taken into account. Several different online reference sources, like Pubmed, SagePub, and Google Scholar were used to do this. It was decided not to take into account review pieces, works that had already been published, or works that were only half done. Result: In the PubMed database, the results of our search get 28 articles, whereas the results of our search on SagePub get 9 articles, on Google Scholar 1680 articles. Records remove before screening are 759, so we get 958 articles fos screening. After we screened based on record exclude, we compiled a total of 10 papers. We included five research that met the criteria. Conclusion: The location of ulcers within the stomach affects the surgical procedure. They may appear with a smaller sac abscess, commonly linked with peritonitis or retroperitoneal abscess. Gastric perforation is a serious and fatal disorder, especially in those who are underweight. Early diagnosis, basic care, primary management, stabilization, nutrient diet, and surgical exploration are all part of initial management.

The diabetic sausage toe: Prevalence, presentation and outcomes.

Osteomyelitis (OM) in diabetic foot infection could have many presentations such as an infected ulcer spreading to the bone or superimposed to Charcot neuroarthropathy. However, the sausage toe as a diabetic OM presentation was very rarely investigated; therefore, this study aims to assess the prevalence and signs of this presentation along with treatment modalities and outcomes. This is a retrospective series of patients presenting a sausage toe on admission. Several methods were conducted to diagnose OM, and three treatment modalities were applied. Two groups were compared: acute and chronic sausage toes. Outcomes were defined as sausage toe prevalence, ulcer location, OM prevalence, and comparative treatment results. Out of 82 diabetic toe infection cases, 24 (30%) presented as 'sausage toe'. The side of the proximal interphalangeal joint of the lateral toes was the most frequent ulcer location (50%), mostly on the dorsal aspect followed by the side aspect. There were 15 (62.5%) acute cases and 9 (37.5%) chronic cases. MRI showed signs of OM in 21 (87.5%) cases and signs of septic arthritis in 3 (12.5%) cases. At the final follow-up, a successful treatment was recorded in five (20%) cases with antibiotics alone. Out of the 19 (42%) procedures, conservative surgery was performed successfully in 8 (58%) cases while amputation was needed in 11 (45.8%) cases. There was no significant difference in amputation frequency between acute and chronic groups. This is the first study documenting the sausage toe as a prevalent presentation of diabetic toe infection. The deformity is conclusive of deep infection with a very high osteomyelitis frequency. Surgery is often required for infection control and healing, mainly for chronic cases, and treatment outcomes did not differ between acute and chronic sausage toe groups. It could be beneficial to include this entity in the diabetic wound classification systems.

Analysis of factors influencing the recurrence of diabetic foot ulcers.

The aim of this study is to investigate the factors influencing the recurrence of diabetic foot ulcers (DFU) and provide guidance for reducing the recurrence rate. A total of 211 patients diagnosed with DFU who were hospitalized and discharged from the hospital from October 2015 to January 2020 were included as the study cohort. Participants were divided into two groups according to whether the foot ulcer recurred during the 2-year follow-up period: a recurrence group (n=84) and a non-recurrence group (n=127). The following data were collected and analyzed for the two groups of patients: general information, foot information, laboratory indicators, diabetes comorbidities, and complications. (1) The overall recurrence rate of diabetic foot ulcers (DFU) within 2 years was 39.8%, indicating a high recurrence rate. (2) Significant differences were observed between the two patient groups in terms of BMI, HbA1c, TBIL, CRP, financial situation, foot deformity, first ulcer on the sole of the foot, previous amputation history, Wagner grade of the first ulcer, osteomyelitis, DFU duration(>60 days), lower limb vascular reconstruction, peripheral arterial disease (PAD), and diabetic peripheral neuropathy (DPN) (t=2.455; Z=-1.988, -3.731, -3.618; χ2=7.88, 5.004, 3.906, 17.178, 16.237, 5.007, 24.642, 4.782, 29.334, 10.253). No significant differences were found for the other indicators. (3) Logistic regression analysis revealed that TBIL (OR=0.886, p=0.036) was a protective factor against ulcer recurrence. In contrast, PAD, previous amputation history, DPN, and the first ulcer on the sole of the foot (OR=3.987, 6.758, 4.681, 2.405; p<0.05 or p<0.01) were identified as risk factors for ulcer recurrence. Early screening and preventive education targeting high-risk factors such as DPN, PAD and the initial ulcer location on the sole of the foot are essential to mitigate the high long-term recurrence rate of DFU. Furthermore, the protective role of TBIL in preventing ulcer recurrence underscores the importance of monitoring bilirubin levels as part of a comprehensive management strategy for DFU patients.

Effect of probiotics on pain and ulceration in patients undergoing fixed orthodontic treatment.

Ulcers caused by mucosal irritation of fixed orthodontic appliances remain an unsolved problem, and more research is needed to improve the pain caused by orthodontic appliances to provide more comfortable treatment for these patients. This study investigated the effect of probiotic Lactogum on pain and ulceration in patients undergoing fixed orthodontic treatment. In this study, 64 patients over 12 years of age and candidates for fixed orthotic treatment were divided into case and control groups (n=32). The control group received orthodontic waxes, and the case group received the same orthodontic waxes and "Lactogum" probiotic lozenges from the beginning of the treatment. The number of ulcers, the amount of pain, and the location of the ulcer were recorded and compared between the two groups. An independent-sample t-test was used to compare the pain level and number of ulcers between the two groups. A significance level of 0.05 was considered for all tests. SPSS 17 was used for data analysis. The mean number of ulcers in the case group was significantly lower than the control group (P<0.001). The mean pain in the case group was significantly lower than in the control group (P<0.001). The most frequent location of ulcers was the buccal mucosa, followed by the labial mucosa. Lactogum probiotic lozenges can reduce traumatic oral ulcers and pain levels in patients undergoing fixed orthodontic treatment. However, larger clinical trials are encouraged to confirm these findings.

Effects of ON101 for Hard-to-Heal Diabetic Foot Ulcers in a Randomized Phase III Trial: A Post Hoc Analysis.

Objective: Hard-to-heal diabetic foot ulcers (DFUs) are associated with higher mortality rates and an increased medical burden for patients. ON101, a new topical cream, exhibited better healing efficacy than the control dressing in a Phase III trial. In this post hoc analysis, we further identify whether ON101 can improve the healing of ulcers with hard-to-heal risk factors in this cohort of DFU patients. Approach: To compare the efficacy of ON101 with absorbent dressing among various hard-to-heal wounds in patients with DFU, a post hoc analysis of a randomized Phase III trial that included 276 DFU patients was performed by subgrouping those patients based on ulcer depth, location, size, duration, and patients' glycated hemoglobin (HbA1c) levels and body mass index (BMI). Results: In the full analysis set, the proportion of patients achieving healing was 61.7% in the ON101 group and 37.0% in the comparator (p = 0.0001). In subgroup analysis according to risk factors, ON101 demonstrated superior healing capacity on Wagner grade 2 ulcers (p < 0.0001); plantar ulcers (p = 0.0016), ulcer size ≥5 cm2 (p = 0.0122), ulcer duration ≥3 months (p = 0.0043); for patients with HbA1c ≥9% (p = 0.0285); and patients with BMI ≥25 (p = 0.0005). Innovation: ON101, a novel therapeutic drug, can modulate the functions of macrophages and demonstrate superior healing rates to conventional absorbent dressing in patients with hard-to-heal DFUs. Conclusions: The results of this post hoc study suggest that ON101 is a better therapeutic option than conventional dressing used in treatment for DFU patients with higher HbA1c, BMI, or ulcers with complex conditions such as longer duration, deeper wounds, larger size, and plantar location.

SOCIOECONOMIC FACTORS AND HEALTHCARE ACCESS: THEIR ROLE IN THE MANAGEMENT AND OUTCOMES OF DIABETIC FOOT ULCERS

Objective: Diabetic foot ulcers (DFUs) are a significant complication of diabetes mellitus, affecting millions globally and presenting considerable challenges to healthcare systems. While clinical aspects of DFUs are well-documented, socioeconomic factors and healthcare access play crucial roles in their management and outcomes. This study investigates how socioeconomic status (SES), healthcare accessibility, and patient education influence DFU prevention, treatment, and prognosis. Methods: A prospective, cross-sectional observational study was conducted over 13 mo at the Department of General Surgery, Command Hospital (Western Command), Chandimandir. Fifty patients with DFUs were enrolled based on specific inclusion and exclusion criteria. Data were collected on demographic details, lifestyle habits, comorbidities, and specifics of diabetes and DFU. Ulcer characteristics, wound cultures, and outcomes were analyzed using SPSS version 21.0. Results: The study population had a mean age of 60.10 y, with a predominance of males (78%). Smoking and obesity emerged as significant risk factors, with smoking more prevalent among males and obesity more common in females. The distribution of ulcer locations and the microbial profile, dominated by Staphylococcus aureus, underline the complexity of DFU management. These findings highlight the influence of socioeconomic factors and healthcare access on DFU outcomes. Conclusion: Effective DFU management requires a holistic approach that extends beyond clinical treatment to address socioeconomic factors and healthcare access. Tailored interventions that consider these broader determinants of health are essential for improving DFU outcomes and patient quality of life. Addressing healthcare disparities can significantly reduce the burden of DFUs, creating a more equitable and effective framework for diabetes care.

Challenging the angiosome concept: Delineating peripheral arterial disease patterns in diabetic foot ulcers.

The angiosome concept has significantly impacted diabetic foot ulcer management by highlighting the vascular anatomy's role in wound healing. However, its clinical applicability and validity remain debated due to complexities in foot blood supply and ulcer location determination. A cross-sectional study was conducted on 84 individuals with diabetic foot ulcers undergoing lower limb angiography. Demographics, ulcer characteristics, and angiographic data were collected and analyzed using descriptive statistics and relevant tests. Digital subtraction angiography assessed 89 limbs with diabetic foot ulcers; males comprised 54.8%, primarily type 2 diabetes (96.4%), averaging 64.36 ± 10.09 years. Of 129 angiosomes, angiosome 2 (40.3%) had the highest ulcer incidence. Posterior tibial artery (PTA) involvement was predominant (72.9%), while external iliac artery (EIA) and profunda femoris artery (PFA) were least affected (2.4% each). Posterior tibial artery showed 46.5% complete occlusion. Angiosome 2 correlated notably with anterior tibial artery (ATA), peroneal artery (CPA), and PTA, but categorizing angiosomes by supply patterns showed no significant artery correlation (p > .05). The research indicates inconsistent support for below-the-knee artery involvement correlating with foot ulcer locations in angiosomes. While aiding vascular comprehension, the angiosome concept may not fully elucidate lower limb vascular complexities and ulcer genesis. Factors like collateral circulation should be noticed to understanding ulcer localization and severity, extending beyond angiosomal arterial supply.

Prognostic indicators of corneal ulcer clinical outcomes at a tertiary care center in the Bronx, New York

PurposeCorneal ulcers frequently result in ocular morbidity and may lead to permanent visual impairment if severe or untreated. This study aims to evaluate the association of patient factors and ocular exam findings on clinical outcomes for patients diagnosed with a corneal ulcer at a tertiary care center in the Bronx, New York.MethodsA retrospective chart review was conducted on all ambulatory and admitted patients diagnosed with a corneal ulcer (identified using ICD-10 code H16.0) at Montefiore Medical Center, Bronx, NY between 2016–2022. Patient demographics, presence of known risk factors, characteristics of subsequent clinical course, and microbiological studies were noted. Clinical outcomes following treatment were longitudinally evaluated and categorized based upon the following criteria: 1) ‘No Surgical Intervention’: No severe complications or surgery required after presentation, 2) ‘Surgical Intervention’: Decline in BCVA with surgery required for a severe complication.ResultsThe search criteria identified 205 patients (205 eyes) with the diagnosis of a corneal ulcer. Mean age was 55.3 ± 21.1 years (mean ± SD). Mean ulcer area at presentation was 7 ± 10.5 mm2. Mean LogMAR at presentation was 1.2 ± 1, and following treatment, improved to 1.0 ± 1. ‘Surgical Intervention’ outcome was associated with advanced age (p = 0.005), presence of ocular surface disease (p = 0.008), central location of ulcer (p = 0.014), greater ulcer area at presentation (p = 0.003), worse visual acuity at presentation (p < 0.001), and isolation of fungi (p = 0.004).ConclusionIdentification of risk factors associated with a poor clinical prognosis can guide treatment and inform expectations for patients diagnosed with a corneal ulcer. Our study highlights the importance of timely diagnosis, work-up, and initiation of appropriate management, particularly in vulnerable populations where access to specialty care is logistically challenging.

Pressure ulcer point prevalence, classification, locations, and preventive measures: Insights from a Norwegian nursing home survey.

To report data from a point pressure ulcer (PU) prevalence survey on prevalence, PU categories, locations and preventive interventions at one Norwegian nursing home. A cross-sectional research design was used. One nursing home in Norway participated in the prevalence survey in 2020. The data were collected on one selected day. A total of 74 out of 88 residents (84.1%) participated. Descriptive statistical analyses were run. The overall prevalence of PUs was 27% amongst all participants in the nursing home, who together had a total of 57 PUs categorised as category I-III. One major finding was that the most common site of the PUs was on the residents' toes. Interestingly, the prevalence of PUs in the residents' sacrum was considerably low. The most frequently used PU preventive interventions were foam chair cushions, nutritional supplements and pressure-reducing heel protection. This study identified a high prevalence of PUs, predominantly on residents' toes. Although preventive strategies were implemented, their application appeared limited. Implementing obligatory care packages and annual nationwide PU surveys might be worth considering in municipalities.

CT venography combined with ultrasound-guided minimally invasive treatment for recurrent varicose veins: a pilot paired-design clinical trial

AimTo compare 1-year outcomes of computed tomography venography (CTV) combined with ultrasound-guided minimally invasive treatment with ascending phlebography and ultrasound-guided treatment for recurrent varicose veins. Materials And MethodsConsecutive patients with unilateral recurrent varicose veins were matched by gender, age, C classification, and degree of obesity, and randomised in a 1:1 ratio to receive either CTV (CTV group) or ascending phlebography (control group) combined with ultrasound-guided minimally invasive treatment. Patients were followed up by clinical and ultrasound examination. Follow-up was scheduled at 1 week, and 3, 6, and 12 months. The primary outcome measure was the Venous Clinical Severity Score (VCSS) at 12 months. Measures of secondary outcome included Chronic Insufficiency Venous International Questionnaire-20 (CIVIQ-20) score, recurrence of varicose vein or ulcer during 12 months, ulcer healing time, detection and location of treated veins. ResultsEighty patients were enrolled. Median VCSS in the CTV group was lower than it in the control group (p=0.04) and the CIVIQ-20 score was higher than the control group (p=0.02). By 12 months, no symptomatically recurrent varicose veins or ulcers had occurred. The ulcer healing time in CTV group was shorter (p<0.01). A greater number of patients had treated veins detected using CTV than by ascending venography (p=0.01), especially among patients with recurrence reflux veins in the groin, perineum, and vulva (p<0.01). ConclusionCTV combined with ultrasound may be more helpful than ascending phlebography combined with ultrasound to improve treatment efficacy for recurrent varices. These results should be verified by an future study with more patients and long-term follow-up.

Індекс системного імунного запалення як корисний інструмент для прогнозування хронічного афтозного стоматиту

Relevance. Chronic recurrent aphthous stomatitis (RAS) is one of the most common chronic inflammatory diseases of the oral cavity, which affects approximately 5 to 25% of the population. RAS is a multifactorial disorder, and studies have pointed to several potential causes associated with its occurrence. The aim is to analyse the role of inflammatory markers in the development of chronic recurrent aphthous stomatitis. Materials and methods. The study involved 80 patients: 29 men (36.25%) and 51 women (63.75%) with RAS who sought help at the Department of Therapeutic Dentistry of the Bogomolets National Medical University. The ulcer severity score (USS) was used to assess and monitor the ulcers according to 6 clinical characteristics: number of ulcers, size of ulcers, duration of ulcers, period without ulcers, pain and location of ulcers. NLR, PLR and SII values were calculated from the results of a complete blood count. The measurements were compared statistically using SPSS software (version 23.0 for Windows). Study results and discussion. The mean USS score was 35.8±7.78 in patients with RAS. NLR values were significantly higher in patients with RAS than in the control group (3.59 ± 2.9 vs. 1.76 ± 2.4, p &lt; 0.001). The values of SII and PLR were statistically higher in patients with RAS compared with the control group (SII, 606.0 ± 2.9 vs. 409.8 ± 2.1 kl/l, p &lt; 0.001; PLR, 192.3 ± 1.9 vs. 105.9 ± 0.96, p = 0.01). Conclusions. NLR, SII, PLR are cheap and simple biomarkers that can be used as markers of inflammation or severity of inflammation in patients with RAS. Key words: chronic aphthous stomatitis, blood, neutrophils, leukocytes, platelets, inflammation, systemic immune inflammation index.

Healing of leprosy-associated chronic plantar wounds with a novel biomembrane containing latex proteins from Calotropis procera.

Pre-clinical assays demonstrated that a 1% polyvinyl alcohol biomembrane containing latex proteins (10%) from the medicinal plant Calotropis procera was biocompatible and stimulated healing of incisional and excisional wounds in murine models, and the mechanistic aspects were established. The efficacy of the biomembrane (BioMemCpLP) to promote healing of chronic ulcers in leprosy patients was investigated. The study started with 28 volunteers. Five were excluded later due to different disconformities. Ulcers from 15 patients were continuously treated with BioMemCpLP for 56 days. Five patients were treated only with silver sulfadiazine and three patients received plain hydrocolloid wound dressings with high absorption capacity. In all cases, wound dressings were renewed three times a week for 56 days and ulcers were evaluated weekly for contraction and healing progress. The extent of the healed area in the ulcers treated with BioMemCpLP was greater than in the control groups. Approximately 88% of ulcers treated with BioMemCpLP were fully healed before day 56, against 6% in both control groups. This result was not correlated with age/gender, duration or location of ulcers, deformity or whether or not the patient was cured of leprosy. The results showed that BioMemCpLP was beneficial for treatment of ulcers suffered by leprosy patients without noticeable side effects.

Prevalence and distribution of recurrent aphthous stomatitis in 10-13 years old: observational study in elementary school

ABSTRACT Introduction: Recurrent aphthous stomatitis (RAS), better known as canker sore, is the most common soft tissue disease of the oral cavity and affects 5 to 66% of the world’s population. RAS often begins in childhood and the age group of 10-14 years has the highest proportion of RAS in children. The purpose of this study was to determine the prevalence and distribution of RAS according to gender and age, clinical characteristics, ulcer location, and predisposing factors in 10 to 13 years old students. Methods: This observational study used cross-sectional design with total sampling method. The data were collected by oral cavity examination using direct observation with a mouth mirror and by filling out 10 closed questions questionnaires about predisposing factors of RAS. The data that had been obtained was tabulated and presented in tabular form using SPSS 16.0. Results: With a total sample size of 79 students from 10-13 years old, this study showed that the prevalence of RAS was found in 16 students (20,25%). The distribution of RAS based on gender was found to be higher in females (11,39%), while based on age, it was found that 11 years of age was the age that suffered the most RAS (10,13%). Based on clinical examination, all of the subjects were categorized as minor, mostly found at labial mucosa and tongue (31,25%). Based on questionnaires, the highest predisposing factor was due to trauma in 11 people (68,75%). Conclusion: In our study, among 10 to 13 year old students with RAS, females were mostly found at 11 years of age, detected with minor clinical characteristics. The labial mucosa and tongue, and trauma were the highest predisposing factors.KEYWORDS: recurrent aphthous stomatitis, children, prevalence, distribution

A Guide to Perforator Flap Selection for Buttock Pressure Sore Reconstruction.

Perforator flaps have been increasingly used to repair stage IV buttock pressure ulcers. However, no one has proposed an approach for stage IV buttock pressure ulcers repairing based on the subregion of buttock pressure ulcers. This study aims to evaluate the effect of perforator flaps in the repair of stage IV buttock pressure ulcers, and flap selection was based on the location of the pressure ulcers. Over the past 5 years, we evaluated 65 cases of stage IV buttock pressure ulcers repaired using perforator flaps. Flap selection was based on the subregion of each buttock pressure ulcer, following our approach. A total of 87 perforator flaps were used for 65 cases, including 42 superior gluteal artery perforator flaps, 19 fourth lumbar artery perforator flaps, and 26 descending inferior gluteal artery perforator flaps. All patients showed satisfactory reconstruction. The authors' approach can support surgeons in selecting the appropriate flaps to repair stage IV buttock pressure ulcers and achieve excellent reconstructive outcomes. This method makes the selection of flaps for pressure ulcer repair systematic, simple, and highly feasible and thus is worthy of promotion.

Australian evidence-based guidelines for the prevention and management of diabetes-related foot disease: a guideline summary.

Diabetes-related foot disease (DFD) - foot ulcers, infection, ischaemia - is a leading cause of hospitalisation, disability, and health care costs in Australia. The previous 2011 Australian guideline for DFD was outdated. We developed new Australian evidence-based guidelines for DFD by systematically adapting suitable international guidelines to the Australian context using the ADAPTE and GRADE approaches recommended by the NHMRC. This article summarises the most relevant of the 98 recommendations made across six new guidelines for the general medical audience, including: prevention - screening, education, self-care, footwear, and treatments to prevent DFD; classification - classifications systems for ulcers, infection, ischaemia and auditing; peripheral artery disease (PAD) - examinations and imaging for diagnosis, severity classification, and treatments; infection - examinations, cultures, imaging and inflammatory markers for diagnosis, severity classification, and treatments; offloading - pressure offloading treatments for different ulcer types and locations; and wound healing - debridement, wound dressing selection principles and wound treatments for non-healing ulcers. For people without DFD, key changes include using a new risk stratification system for screening, categorising risk and managing people at increased risk of DFD. For those categorised at increased risk of DFD, more specific self-monitoring, footwear prescription, surgical treatments, and activity management practices to prevent DFD have been recommended. For people with DFD, key changes include using new ulcer, infection and PAD classification systems for assessing, documenting and communicating DFD severity. These systems also inform more specific PAD, infection, pressure offloading, and wound healing management recommendations to resolve DFD.
