Tik Tok is an emerging social media platform that provides a novel opportunity for health practitioners such as dermatologists to disseminate accurate health information.

This study systematically evaluated and ranked the efficacy of first- and second-line antibiotics antibiotic options for the clinical management of cellulitis and erysipelas through a network meta-analysis approach. From inception to July 04, 2024, a search for relevant randomized clinical trials (RCTs) was carried out using several databases. Antibiotics including azithromycin, cefaclor, cephalexin, cloxacillin, erythromycin, cephalexin plus trimethoprim-sulfamethoxazole, cephalexin plus placebo, flucloxacillin, clindamycin, ceftriaxone, penicillin, roxithromycin, and pristinamycin were assessed regarding cure rate, the eradication of baseline pathogens, diarrhea or vomiting, and rash. In total, 10 RCTs with 1,936 cellulitis or erysipelas patients were eligible for inclusion. There were no significant differences in the cure rates for cellulitis among the antibiotics analysed, with cefaclor demonstrating the most favorable profile for curative outcomes. In terms of side effects, ceftriaxone was identified as the least likely to induce diarrhea or vomiting. For erysipelas, pristinamycin showed the most promising results in achieving cure rates. Although a comparison of the three antibiotics revealed no significant differences in rash as a side effect in erysipelas, pristinamycin was observed to carry the highest risk for rash. Our findings indicate no significant differences in cure rates among antibiotics for cellulitis. However, ceftriaxone had the fewest gastrointestinal side effects. Pristinamycin showed the highest cure rates for erysipelas but with a higher risk of rash. Future research should focus on optimizing antibiotic selection for cellulitis and erysipelas.

Skin and soft tissues are among the most common sites of infections. Infections can involve the superficial epidermis to deep muscles and bones. Most infections spread through contiguous structures, although hematogenous spread can occur in the setting of an immunocompromised state and with atypical infections. While clinical diagnosis of infections is possible, it often lacks specificity, necessitating the use of imaging for confirmation. Cross-sectional imaging with US, CT, and MRI is frequently performed not just for diagnosis, but to delineate the extent of infection and to aid in management. Nonetheless, the imaging features have considerable overlap, and as such, it is essential to integrate imaging features with clinical features for managing soft tissue infections. Radiologists must be aware of the imaging features of different infections and their mimics, as well as the pros and cons of each imaging technique to properly use them for appropriate clinical situations. In this review, we summarize the most recent evidence-based features of key soft tissue infections. [ABSTRACT FROM AUTHOR]

In modern practice, imaging plays an integral role in the diagnosis, evaluation of extent, and treatment planning for lower extremity infections. This review will illustrate the relevant compartment anatomy of the lower extremities and highlight the role of plain radiographs, CT, US, MRI, and nuclear medicine in the diagnostic workup. The imaging features of cellulitis, abscess and phlegmon, necrotizing soft tissue infection, pyomyositis, infectious tenosynovitis, septic arthritis, and osteomyelitis are reviewed. Differentiating features from noninfectious causes of swelling and edema are discussed. [ABSTRACT FROM AUTHOR]

Musculoskeletal infections in the ER are not an uncommon presentation. The clinical context is critical in determining the suspicion for infection and degree of tissue involvement which can involve all layers from the skin to bones. The location, extent, and severity of clinically suspected infection directly relate to the type of imaging performed. Uncomplicated cellulitis typically does not require any imaging. Localized and superficial infections can mostly be evaluated with ultrasound. If there is a diffuse site (an entire extremity) or suspected deeper involvement (muscle/deep fascia), then CT is accurate in diagnosing, widely available, and performed quickly. With potential osseous involvement, MRI is the gold standard for diagnosing acute osteomyelitis; however, it has the drawbacks of longer scan times, artifacts including patient motion, and limited availability.

Skin and soft tissue infections (SSTIs) are among the most common indications for antimicrobial prescribing in hospitals. Inappropriate antimicrobial use can lead to increased morbidity, unnecessary hospital re-admission and increased antimicrobial resistance. This study aimed to assess the quality of antimicrobial prescribing practices in SSTI management within Australian hospitals to provide guidance for future practice. A retrospective analysis was conducted with data from the National Antimicrobial Prescribing Survey (NAPS). SSTI prescribing data from Hospital NAPS (2013–2022) and surgical site infection data from Surgical NAPS (2016–2022) datasets were analysed. Variables assessed included guideline compliance, appropriateness as per the structured NAPS algorithm, and reasons for inappropriateness. From the Hospital NAPS dataset, 40,535 antimicrobial prescriptions for SSTIs were analysed. The most common indication was cellulitis (34.1%, N =13,822), and the most prescribed antimicrobial was flucloxacillin (18.8%, N =7,638). SSTI indications had a lower rate of guideline compliance but a higher rate of appropriateness compared with all other indications for antimicrobial prescriptions (guideline compliance 66.3%, N =21,035 vs 67.4%, N =156,285; appropriateness 75.6%, N =30,639 vs 72.7%, N =209,383). The most common reason for inappropriateness was incorrect dose or frequency (29.3%, N =2367). From the Surgical NAPS dataset, 5674 prescriptions for surgical site infections were analysed. Of these, 68.2% (N =3867) were deemed to be appropriate. The most common reason for inappropriateness was incorrect dose or frequency (27.7%, N =350). As SSTIs are a common indication for prescribing an antimicrobial in Australian hospitals, identifying effective antimicrobial stewardship strategies to optimize antimicrobial use for SSTI management is recommended to improve patient outcomes.

Background Methicillin-resistant Staphylococcus aureus (MRSA) sequence type (ST) 45 is a globally disseminated MRSA lineage. Herein, we investigated whether MRSA ST45 isolates from cellulitis and from osteomyelitis display distinctive phenotypic and genomic characteristics. Methods A total of 15 MRSA ST45 isolates from cellulitis (CL-MRSA; n = 6) or osteomyelitis (OM-MRSA; n = 9) were collected in a Taiwan hospital. These MRSA ST45 isolates were characterized for their antimicrobial susceptibility, biofilm-forming ability, cellular infectivity in vitro, and pathogenicity in vivo. Four CL-MRSA and 6 OM-MRSA ST45 isolates were selected for whole-genome sequencing (WGS). Results Antibiotic resistance tests showed that all OM-MRSA ST45 strains, but not CL-MRSA ST45 strains, were resistant to ciprofloxacin, levofloxacin, gentamicin, and doxycycline. Compared to the CL-MRSA ST45 isolates, the OM-MRSA ST45 isolates had stronger biofilm-forming ability and cellular infectivity and caused more severe disease in mice. WGS analysis revealed that these OM-MRSA ST45 isolates carry multiple common mutations or polymorphisms in genes associated with antibiotic resistance and virulence. Moreover, the transposable elements IS 256 and IS 257 R2 were found only in the OM-MRSA ST45 isolates. Conclusions The emergence and spread of the highly pathogenic and multidrug-resistant ST45 MRSAs identified from osteomyelitis may pose a serious threat on public health. [ABSTRACT FROM AUTHOR]

PurposeMethodsResultsConclusionTo characterize trends in orbital cellulitis (OC) severity and management from 2016 through 2022, including assessment of effects from the COVID-19 pandemic.A retrospective chart review was conducted at a tertiary care center using an electronic medical record search of OC from January 1 2016 to January 1 2023. Radiography was used to categorize patients into three cohorts – OC without abscess, OC with subperiosteal abscess (SPA), and OC with orbital abscess (OA). Infection cohort and age group [pediatric (<9 years old), adolescent (9–18 years), adult (>18 years)] were compared across years. Subgroup analysis was performed in the SPA cohort. Comparisons were made between the time periods prior to and after the start of the COVID-19 pandemic.From 2016–2022, there were 247 (67.3%) cases of OC, 103 (28.1%) SPA, and 17 (4.6%) OA. The year 2022 incurred higher rates of SPA and OA (p = 0.035), pediatric infections (p = 0.008), and co-morbid sinusitis (p = 0.005) compared to all preceding years. Rates were similar from 2016 through 2021. Within the SPA cohort, rates of surgical intervention and outcomes were similar across all years. Rate of abscess formation was significantly higher during the COVID-19 pandemic compared to the pre-pandemic era (p = 0.033).The severity of OC leading up to the COVID-19 pandemic appeared steady. After pandemic onset, a delayed increase in abscess formation, predominantly affecting pediatric patients and correlating with a greater rate of sinusitis, was observed in 2022.

Simple Summary: Data collected during meat inspection in slaughterhouses are invaluable for monitoring and surveilling the welfare and health of broilers These inspections help to ensure that meat products meet regulatory standards for food safety and animal welfare. The objective of this study was to assess, in three different slaughterhouses, the health and welfare of different commercial broiler flocks based on welfare indicators observed from the animals. Emaciation, dirty feathers (DFs), footpad dermatitis (FPD), hock burn (HB), breast burn (BB), breast blister, breast ulcer, ascites, septicemia/abnormal color, cellulitis, extensive traumatisms (affecting at least two distinct body parts), dead on arrival (DoA) and condemnation rate were the indicators measured. The results were considered unsatisfactory if thresholds were exceeded for DoA (>0.5%), condemnation rate (>4%), or extensive traumatisms (>2%) or grades 1 or 2 were achieved for DFs, FPD, HB, BB, breast blister, and breast ulcer. Eleven houses exceeded the thresholds for at least two welfare indicators, leading to audits of those farms. During farm audits, the main weaknesses identified included environmental conditions such as house temperature, ventilation, lighting programs, high stocking densities, structural infiltrations, water leakage and litter quality. The objective of this study was to assess the health and welfare of 70 commercial broiler flocks (transport batches) in three distinct slaughterhouses based on various indicators including emaciation, dirty feathers (DFs), footpad dermatitis (FPD), hock burn (HB), breast burn (BB), breast blister, breast ulcer, ascites, septicemia/abnormal color, cellulitis, extensive traumatisms, dead on arrival (DoA) and condemnation rate. Assessment scales ranging from 0 (absence) to 2 (severe) were used for DFs, FPD, and HB, while a 0 (absence) to 1 (present) scale was applied to BB, breast blisters, and breast ulcers. The prevalence of total condemnation causes (emaciation, ascites, septicemia/abnormal color, cellulitis, and extensive traumatism) and DoA were recorded and presented in percentages. Three flocks presented condemnation rates higher than 4% and 11 flocks presented DoA rates higher than 0.5%. Twenty-one flocks achieved grade 1 (warning) for FPD and 14 achieved grade 2 for FPD (alarm). Extensive trauma was observed in 0.01% of the slaughtered animals, and no flock reached the threshold of 2%. Breast blisters and breast ulcers lesions were not observed in the studied flocks. The significant positive associations observed for the presence of severe footpad dermatitis (FPD2), severe hock burns (HB2), and breast burns (BB1) indicate simultaneous occurrences. Absences of hock burns (HB0) and breast burns (BB0) were also associated. Eleven houses that obtained the worst results for welfare indicators at slaughterhouses were audited. FPD, HB, DoA, and the condemnation rate were the most crucial indicators for identifying farms with inadequate welfare conditions. These indicators should be systematically integrated into the welfare monitoring of broilers in slaughterhouses. Audits conducted on farms detected some noncompliance with regulatory welfare standards and suggested improvements in environmental and structural conditions, as well as the reduction in stocking densities and improvements in the water systems.

Background: Orbital cellulitis is a severe, potentially life-threatening condition that often arises as a complication of sinusitis, trauma, or dental infections. Prompt diagnosis and effective management are crucial to prevent serious outcomes such as vision loss and intracranial complications. This case series explores the diverse clinical presentations, radiological findings, and management strategies for orbital cellulitis, with a particular focus on cases complicated by underlying systemic conditions and coexisting orbital pathologies. Methods: A retrospective analysis was conducted on five patients diagnosed with orbital cellulitis at a tertiary care center in India. The cases included orbital cellulitis secondary to sinusitis, trauma, dental infections, and in an immunocompromised patient with uncontrolled diabetes. Each case was evaluated based on clinical presentation, radiological imaging (CT and MRI), bacteriological findings, and treatment outcomes. The results were compared with findings from other studies to provide a comprehensive understanding of the condition. Results: Sinusitis was the most common etiology, consistent with global data, but trauma and dental infections also played significant roles. Radiological imaging, particularly CT scans, was essential in identifying abscess formation and guiding surgical intervention. MRI was crucial in cases with suspected intracranial extension. Complications such as intracranial abscess and prolonged recovery were observed, particularly in the immunocompromised patient. Multidisciplinary management, including intravenous antibiotics and timely surgical intervention, was vital in achieving favorable outcomes. Conclusion: This case series underscores the complexity of orbital cellulitis, particularly when complicated by systemic conditions or coexisting orbital pathologies. Accurate and timely diagnosis using radiological imaging, coupled with a multidisciplinary approach, is critical in managing this condition effectively. Future research should continue to explore the impact of emerging antibiotic resistance and refine treatment protocols for high-risk populations. [ABSTRACT FROM AUTHOR]

Background: In the absence of a gold-standard diagnostic modality for cellulitis, sterile inflammatory disorders may be misdiagnosed as cellulitis. Objective: To determine the utility of skin biopsy and tissue culture for the diagnosis and management of patients admitted with a diagnosis of presumed cellulitis. Design: Pilot single-blind parallel group randomized controlled clinical trial in 56 patients with a primary diagnosis of presumed cellulitis. In the intervention group only, skin biopsy and tissue culture results were made available to the primary care team to guide diagnosis and management. Length of hospital stay and antibiotic use were evaluated as outcome measures. Results: Length of stay showed the greatest opportunity for further study as a primary outcome (intervention: 4, IQR (2–6) vs. control: 5 IQR (3–8) days; p = 0.124). Limitations: The COVID-19 pandemic placed limitations on participant enrollment and study duration; in addition, data was collected from a single medical center. Conclusion: This study demonstrates that length of stay and anti-pseudomonal antibiotic de-escalation are endpoints that may be influenced by biopsy and tissue culture results in presumed cellulitis patients; these outcomes warrant further study.

We conducted a prospective study of 159 cases of Streptococcus dysgalactiae subspecies equisimilis (SDSE) bacteremia in 157 patients at 2 hospitals in Finland during November 2015–November 2019. Cellulitis was associated with nonsevere disease (p = 0.008); necrotizing fasciitis was associated with severe disease (p = 0.004). Fifty percent of patients had >1 clinical characteristic associated with risk for death. The case-fatality rate was 6%, and 7% of patients were treated in an intensive care unit. Blood leukocyte counts on days 2 (p = 0.032) and 3 (p = 0.020) and C-reactive protein levels on days 3 (p = 0.030) and 4 (p = 0.009) after admission were predictors of severe disease. The Pitt bacteremia score was an accurate predictor of death. Using the Pitt bacteremia score, leukocyte counts, and CRP responses during initial treatment can improve treatment strategies and survival for patients with SDSE. [ABSTRACT FROM AUTHOR]

Nasal natural killer/T-cell lymphoma (NK/TCL) is a rare form of malignant non-Hodgkin lymphoma (NHL) with a far more rare involvement of orbit. The orbital involvement has a highly variable clinical presentation. Here, we report one such case of a 40-year-old male patient who presented with swelling in the right upper and lower eyelids with the diminution of vision for 12 days. He had a history of blocked nose for two months. Clinical examination and CT scan of the orbit and paranasal sinuses suggested a diagnosis of right orbital cellulitis with pansinusitis. A combination of intravenous antibiotics was started, and functional endoscopic sinus surgery was done. Histopathology was a suggestive of nasal NK/TCLl NHL. After proper staging, the patient was given chemotherapy and radiotherapy. There was a complete resolution of mass with no recurrence over a follow-up of 10 months. [ABSTRACT FROM AUTHOR]

Ocular dirofilariasis is no longer a rare disease as more cases are being reported across the world and in India as awareness about this disease among health care professionals has increased. It is a helminthic infection which is caused by filarial parasite of the genus dirofilaria. It has a varied clinical presentation and the definitive diagnosis is based on microbiological and histopathological examination of the parasite. Herein, we report a unique case of ocular dirofilariasis in which a patient initially presented with features mimicking orbital cellulitis. Subsequently, the patient developed a subconjunctival lesion when orbital cellulitis subsided after three days of broad-spectrum antibiotics. The live worm was found when the lesion was incised, which was removed in toto and sent for microbiological examination. The nematode in our case was identified as dirofilaria repens. There was complete resolution of symptoms following surgical extraction of worm and no sign of recurrence was seen at 6 months follow-up. [ABSTRACT FROM AUTHOR]

Objective: There is substantial practice variation in the management of cellulitis with limited prospective studies describing the course of cellulitis after diagnosis. We aimed to describe the demographics, clinical features (erythema, warmth, swelling and pain), patient‐reported disease trajectory and medium‐term follow‐up for ED patients with cellulitis. Methods: Prospective observational cohort study of adults diagnosed with cellulitis in two EDs in Southeast Queensland, Australia. Patients with (peri)orbital cellulitis and abscess were excluded. Data were obtained from a baseline questionnaire, electronic medical records and follow‐up questionnaires at 3, 7 and 14 days. Clinician adjudication of day 14 cellulitis cure was compared to patient assessment. Descriptive analyses were conducted. Results: Three‐hundred patients (mean age 50 years, SD 19.9) with cellulitis were enrolled, predominantly affecting the lower limb (75%). Cellulitis features showed greatest improvement between enrolment and day 3. Clinical improvement continued gradually at days 7 and 14 with persistent skin erythema (41%) and swelling (37%) at day 14. Skin warmth was the feature most likely to be resolved at each time point. There was a discrepancy in clinician and patient assessment of cellulitis cure at day 14 (85.8% vs. 52.8% cured). Conclusions: A clinical response of cellulitis features can be expected at day 3 with ongoing slower improvement over time. Over one third of patients had erythema or swelling at day 14. Patients are less likely than clinicians to deem their cellulitis cured at day 14. Future research should include parallel patient and clinician evaluation of cellulitis to help develop clearer definitions of treatment failure and cure. [ABSTRACT FROM AUTHOR]

Here, we report the simultaneous isolation of Pseudomonas straminea from blood cultures and from a skin ulcer in an elderly woman who suffered from atopic dermatitis and psoriasis and developed acute cellulitis of both arms requiring hospital treatment. To the best of our knowledge, P. straminea has not been previously reported to cause invasive infections in humans. This case highlights how chronic diseases and older age increase the susceptibility to bacterial infections with environmental bacteria of low virulence. Our study describes the microbiological identification of the blood culture isolate, including morpho-molecular characterization and virulence demonstration in a Galleria mellonella model.

Fungal rhinosinusitis (FRS) includes non-invasive and invasive subtypes with the latter having significant morbidity and mortality. This systematic review aims to identify the imaging features most correlated with invasive fungal rhinosinusitis (IFRS) and present a checklist of these features to aid diagnosis. PubMed, Embase, CENTRAL, and Science Direct were searched from inception to May 2023, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. Primary research articles published in English describing the imaging features of IFRS were included. The systematic review was conducted in accordance with the PRISMA guidelines. Forty-eight articles were identified for inclusion. Six studies examined radiological features in acute invasive fungal rhinosinusitis (AIFRS), and 9 studies of chronic invasive fungal rhinosinusitis (CIFRS). A majority of studies did not specify whether IFRS cases were acute or chronic. On CT, bony erosion and mucosal thickening were the most common features. Other features include nasal soft tissue thickening, nasal cavity opacification, opacification of the affected sinus, and perisinus soft tissue infiltration. Extra-sinus extension was commonly observed on MRI, most often invading intraorbitally and intracranially. Other sites of extra-sinus extension included the cavernous sinus, pterygopalatine fossa, infratemporal fossa, masticator space, and facial soft tissue. IFRS is a condition with potential for high morbidity and mortality. Several radiological features are highly suggestive of IFRS. Early identification of high-risk radiological features using a checklist may aid prompt diagnosis and early treatment. Future research investigating the radiological differentiation between IFRS and other significant pathology including bacterial orbital cellulitis would be beneficial. [ABSTRACT FROM AUTHOR]

The Hong Kong Journal of Emergency Medicine has collaborated with international emergency medicine journals to share important research studies. One study from the African Journal of Emergency Medicine examined the assessment and reassessment of injured patients in non-tertiary hospitals in Ghana. The study found that while initial assessments were generally adequate, reassessment rates were very low, even for seriously injured patients. Another study from the Annals of Emergency Medicine discussed the dangers of xylazine, a veterinary sedative, being associated with opioid overdose deaths in the United States. The study emphasized the importance of providing ventilatory support and naloxone in overdose management. This article focuses on a randomized controlled trial conducted at an Australian level 1 trauma center, which investigated the effects of integrating pharmacists into trauma response teams to enhance analgesia delivery and medication management. The trial involved 82 patients, and the primary outcome was the proportion of patients who received the first dose of analgesia within 30 minutes. The results demonstrated that the inclusion of an emergency medicine pharmacist in the trauma response team improved the time to analgesia and optimized medication management. This intervention may enable other team members to concentrate on life-saving interventions. [Extracted from the article]

A 75-year-old immunocompetent male presented with a right orbital cellulitis after a foreign body penetrating injury. He was taken for orbitotomy with foreign body removal and started on broad-spectrum antibiotics. Intra-operative cultures were positive for Cladophialophora bantiana, a mold known for causing brain abscesses with no prior reports of orbital invasion in the literature. Following culture results, the patient was managed with voriconazole and required multiple orbitotomies and washouts for infection control. [ABSTRACT FROM AUTHOR]

PurposeMethodsResultsConclusionTo evaluate the results of a minimally invasive combined endoscopic and eyelid crease/medial suprabrow incision approach in collaboration with oculoplastic and sinus surgeons for the treatment of recurrent/recalcitrant sino-orbital mucoceles.Eighteen cases of recurrent/recalcitrant sino-orbital mucoceles, treated in collaboration with oculoplastic and sinus surgeons at the University of Michigan, were retrospectively reviewed. The recurrence of mucocele, reduction in proptosis, and complications were evaluated.The mean age at the time of surgery was 49 years (range: 17–76 years). All cases had a history of previous sinus or orbital surgeries for mucoceles. Among 18 cases, eight were due to chronic sinus infections, six due to trauma, three due to Schneiderian papilloma, and one case was secondary to an inflammatory sinus disease. Thirteen cases (72%) presented with orbital or facial cellulitis, while five cases (38%) experienced periocular swelling and limited extraocular motility. Following a mean follow-up of 19 months (range: 1–76 months)), recurrence was observed in two cases (11%): one in a cystic fibrosis patient with chronic sinusitis, and the other in a case of Schneiderian papilloma. The mean pre-operative proptosis in the affected eye was 2.78 mm, with an average decrease of 2.33 mm after surgery. Complications occurred in two cases, including one case of hypoesthesia in the forehead and one case of post-operative strabismus.Our series of 18 cases of recurrent/recalcitrant mucoceles, with only two cases of recurrence, demonstrates that this minimally invasive approach can be successfully employed for advanced sino-orbital disease, with a low rate of adverse outcomes and aesthetically pleasing results.

INTRODUCTION: Enfortumab vedotin is an antibody drug conjugate approved for management of pretreated locally advanced or metastatic urothelial carcinoma, which is associated with a rare risk of drug extravasation and soft tissue reactions. CASE REPORT: We report two cases of EV extravasation with subsequent development of bullae and cellulitis. MANAGEMENT AND OUTCOME: They were both treated for cellulitis and had conservative management without surgical intervention and were able to resume treatment with Enfortumab vedotin without subsequent adverse events. DISCUSSION: We propose that EV acts as a vesicant upon extravasation, highlight measures to prevent extravasation events, and encourage appropriate measures when dealing such as attempt of aspiration, removal of catheter, application of compresses, and thorough documentation with photographic evidence.

Background: Many patients with cellulitis are treated with oral antibiotics as outpatients, but some require hospital admission for intravenous antibiotics. During the coronavirus disease 2019 pandemic, Betsi Cadwaladr University Health Board in Wales approved use of dalbavancin as first-line intravenous antibiotic from April to December 2020 to facilitate early discharge and prevent hospital admission. Objectives: To report cost savings and admission avoidance through first-line intravenous use of dalbavancin for cellulitis in one health board in Wales. Patients and methods: Patients with cellulitis who presented to the emergency department or medical assessment unit at Betsi Cadwaladr University Health Board's two hospitals between April and December 2020 were identified for treatment with dalbavancin, because they had not responded to oral antibiotics or their initial presentation warranted intravenous antibiotics. Patients received 1500 mg dalbavancin by intravenous infusion according to prescribing information and were sent home without being admitted. Outcomes were admission within 30 d of dalbavancin and cost savings from avoiding admission. Results: 31 patients were treated with dalbavancin for cellulitis in the emergency department or medical assessment unit. No patient was admitted within 30 d of receiving dalbavancin. Use of dalbavancin is estimated to have saved 248 bed-days over the study period, with an estimated saving of $120,444.23 based on avoidance of admission. The cost of dalbavancin for these 31 patients was $69,959.08, giving an overall cost saving of $50,485.15 ($1529.95 per patient). Conclusions: Prescribing dalbavancin as first-line intravenous antibiotic for cellulitis prevents admission, saving bed-days and admission-related costs.

Abstract Purpose Despite a known risk of cellulitis recurrence, the management of the wider impact and risk factors has been neglected. The innovative National Cellulitis Improvement Programme (NCIP) addresses this by providing evidence-based and individualised care to improve patient reported outcomes and reduce the risk of recurrence. The aim of this paper is to examine the longer-term impact of cellulitis and to identify a suitable and clinically relevant Patient Reported Outcome Measure (PROM). Methods A review of existing cellulitis-specific PROMs was undertaken, alongside literature detailing the patient-focused impact of cellulitis, to identify a suitable PROM for clinical use. A group of expert therapists and patient representatives (n = 14) shared their individual and collective experiences over a series of events to discuss and debate the impact of cellulitis and review available PROMs. CELLUPROM© is introduced with anonymised PROM data and case study information reported to establish the impact of CELLUPROM© within usual NCIP care. Results No cellulitis-specific PROMs were identified. Literature focused on the signs and symptoms of an acute episode of cellulitis, with outcome measures primarily used to evidence the impact of an intervention. An enduring physical, social and emotional impact of cellulitis was identified in this study, providing the basis for the new cellulitis-specific PROM (CELLUPROM©), which has been implemented with good effect in clinical care. Conclusion This study has highlighted the lasting impact of cellulitis. Using CELLUPROM© within the risk-reduction NCIP has helped develop Value-Based Healthcare and support programme evaluation.

Introduction: Reactive angioendotheliomatosis (RAE) is a rare, benign, angioproliferative disorder with poorly understood aetiopathogenesis. It is characterised by vascular occlusion that occurs in patients with coexistent systemic or autoimmune disease. Case Presentation: A 60-year-old female presented with an 8-week history of a painful, non-healing, and non-traumatic ulcer on the left thigh. Her past medical history included smoking, peripheral vascular disease (PVD) and previously treated rectal squamous cell carcinoma. The diagnosis of pyoderma gangrenosum with superimposed cellulitis was considered and treatment with oral antibiotics was initiated. Following failure to improve, a biopsy was undertaken leading to the diagnosis of RAE. The patient was referred for urgent consideration of surgical correction of PVD, but was deemed unsuitable for surgical treatment due to a poor performance status. The patient was treated with conservative measures, but her condition rapidly deteriorated and she passed away a few weeks later. Conclusion: RAE is notorious for mimicking a wide spectrum of diseases. It is an important differential diagnosis to consider in patients with non-healing ulceration and underlying systemic or autoimmune disorders. Our case raises awareness of this rare condition and the mortality that it carries if left untreated. In an attempt to reverse disease progression and mortality, we urge clinicians to attempt surgical correction of PVD even when faced with multiple comorbidities and poor performance status.

Abstract Introduction The outpatient parenteral antibiotic therapy (OPAT) program of Vancouver General Hospital (VGH) was supervised by emergency physicians (EPs) until 2017 when infectious disease (ID) physicians began assisting in management. We designed a retrospective study to determine whether ID involvement led to improved outcomes. Methods This study analyzes the impact of ID involvement by comparing the mean days patients spent on OPAT with ID involvement versus EPs alone through a retrospective chart review. Secondary research objectives were to compare patient care decisions, e.g., antibiotic choice, tests ordered, and final diagnosis. Results There was no difference between the mean number of days on OPAT between physician types. Compared to historic patterns, patients seen in OPAT after increased ID consultation spent an average of 0.5 fewer days in the program. However, when grouped by the first day of ID assessment, the average total days in OPAT was closely aligned with the day of first ID assessment, implying that ID frequently discharged patients close to initial assessment. Patients seen by ID were less likely to return within one month of discharge compared to those not seen by ID. Secondary findings include ID physicians prescribing a greater range of antibiotics, providing more varied final diagnoses, prescribing antibiotics less frequently, as well as ordering more cultures, diagnostic imaging and specialist consults. Discussion The findings of this study support the hypothesis that ID involvement in OPAT programs leads to changes in care that may have beneficial outcomes for patients and the healthcare system.

Background Orbital complications arising from acute rhinosinusitis (ARS) are a major concern for clinicians and serve as important warning indicators of ARS. Prompt recognition and appropriate management are crucial for preventing potential vision-threatening sequelae. Orbital complications of rhinosinusitis are markedly more common in children than in adults. The aim of this study was to investigate the clinical characteristics and treatment outcomes of orbital complications of ARS in adult patients. Methods This retrospective observational cohort study analyzed the medical records of 176 patients admitted for orbital cellulitis/abscess (ICD code: H050) who underwent orbit or paranasal computed tomography from January 2001 to February 2022 at a tertiary hospital. Results Eighteen adults with a mean age of 53.2±18.9 years were diagnosed with orbital complications due to ARS: five (27.8%) had preseptal cellulitis, eight (44.4%) had orbital cellulitis, and five (27.8%) had subperiosteal orbital abscess. None of the patients had an orbital abscess or cavernous sinus thrombosis. All patients had unilateral orbital complications (7 right and 11 left) and were managed with intravenous antibiotics for an average of 10.3±6.6 days. Five patients with subperiosteal orbital abscesses underwent intranasal endoscopic drainage at an average of 1.4±1.9 days after admission, while two patients required additional external drainage. Complete recovery was observed in all patients. Conclusions Conservative antimicrobial therapy can be effective for treating orbital complications from ARS, and not all adult patients require immediate surgical intervention for subperiosteal abscesses. Nonetheless, careful monitoring is essential, and an ophthalmologist must check patients’ visual acuity to prevent irreversible blindness.

Abstract Background Cellulitis is defined as a bacterial infection of the skin and subcutaneous tissue that can cause multiple complications, such as sepsis and necrotizing fasciitis. In extreme cases, it may lead to multiorgan failure and death. We sought to analyze the clinical factors that contribute to the development of complicated disease, including demographics, clinical presentation, initial vital signs, and laboratory studies. Methods Our study is a retrospective cohort study carried out in a university-based tertiary care hospital in Bangkok, Thailand. Adult patients who presented with cellulitis from January 1, 2018, to December 31, 2022, were evaluated for eligibility and inclusion in this study. All related variables for both outcomes, bacteremia and necrotizing fasciitis, were gathered from electronic medical records and analyzed using multivariable logistic regression analysis. Results Of the 1,560 visits to this hospital, 47 cases reported at least one complication, with bacteremia noted in 27 visits (1.73%) and necrotizing fasciitis in 20 visits (1.27%). From the multivariable logistic regression analysis, six variables emerge as predictors of cellulitis complications. These are: Age ≥ 65 years, Body Mass Index ≥ 30 kg/m2, diabetes mellitus, body temperature ≥ 38 °C, systolic blood pressure ≤ 100 mmHg, and involvement of lower extremities. The predictive score was developed from these factors and was named the Ramathibodi Necrotizing Fasciitis/Bacteremia (RAMA-NFB) Prediction Score. Our predictive score has an accuracy of 82.93% (95% CI, 0.77–0.89). Patients in the high-risk group (RAMA NFB score > 6) have a likelihood ratio of 8.75 (95% CI, 4.41–18.12; p

This report seeks to discuss sequelae of chronic cellulitis that is commonly treated in the ambulatory setting, as exacerbated by the conditions of living outside. Further we hope to identify etiologic factors that contribute to complication development. Additionally, this article will touch on unique treatment plan considerations for unhoused patients with the intention to educate providers and reduce mortality and morbidity relating to pedal skin and soft tissue infections in this population. This piece examines the case of a 52-year-old man with a history of chronic diseases, substance use disorder, and recurrent cellulitis. We highlight systemic issues in healthcare delivery for unhoused patients, including inadequate discharge planning, limited access to medication, and challenges in shelter placement. The discussion section emphasizes the importance of accurate diagnosis and tailored treatment plans for cellulitis in houseless individuals, the importance of a multidisciplinary approach incorporating social work services, and addressing chronic illnesses, substance use disorder, and housing issues. The report advocates for heightened awareness of bilateral cellulitis in unhoused populations, emphasizing the need for comprehensive, individualized treatment plans. [ABSTRACT FROM AUTHOR]

Background: Trigeminal trophic syndrome is a rare cranial and facial condition caused by damage to the central or peripheral branches of the trigeminal nerve. This syndrome consists of a triad of anesthesia, paresthesia, and crescent-shaped facial ulcer involving the ala nasi and sometimes extending to the upper lip. Although previous screening for human immunodeficiency virus in some patients with trigeminal trophic syndrome was negative, we present a unique case of trigeminal trophic syndrome who tested positive for human immunodeficiency virus with eye complications. Case presentation: We present a rare case of trigeminal trophic syndrome in a 44-year-old Black African woman who tested positive for human immunodeficiency virus. She presented with a 6-week history of progressive, persistent, and painless left sided facial and scalp ulcerations that started as small skin erosion. Diagnosis of trigeminal trophic syndrome was made on clinical grounds based on the triad of anesthesia, paresthesia, and unilateral crescent-shaped ulcer in the trigeminal dermatome and her past medical history. The ulcer healed completely after counseling and pharmacological therapy, but she later developed left periorbital cellulitis and left upper eyelid full-thickness defect. Conclusion: This is by far the first documented case of trigeminal trophic syndrome with a positive human immunodeficiency virus test. Testing for human immunodeficiency virus in patients with trigeminal trophic syndrome is necessary as this can help improve clinical management and treatment outcomes. Seeking the services of specialists remotely in resource constraint settings is beneficial for managing complications associated with trigeminal trophic syndrome. [ABSTRACT FROM AUTHOR]

Purpose: Despite a known risk of cellulitis recurrence, the management of the wider impact and risk factors has been neglected. The innovative National Cellulitis Improvement Programme (NCIP) addresses this by providing evidence-based and individualised care to improve patient reported outcomes and reduce the risk of recurrence. The aim of this paper is to examine the longer-term impact of cellulitis and to identify a suitable and clinically relevant Patient Reported Outcome Measure (PROM). Methods: A review of existing cellulitis-specific PROMs was undertaken, alongside literature detailing the patient-focused impact of cellulitis, to identify a suitable PROM for clinical use. A group of expert therapists and patient representatives (n = 14) shared their individual and collective experiences over a series of events to discuss and debate the impact of cellulitis and review available PROMs. CELLUPROM© is introduced with anonymised PROM data and case study information reported to establish the impact of CELLUPROM© within usual NCIP care. Results: No cellulitis-specific PROMs were identified. Literature focused on the signs and symptoms of an acute episode of cellulitis, with outcome measures primarily used to evidence the impact of an intervention. An enduring physical, social and emotional impact of cellulitis was identified in this study, providing the basis for the new cellulitis-specific PROM (CELLUPROM©), which has been implemented with good effect in clinical care. Conclusion: This study has highlighted the lasting impact of cellulitis. Using CELLUPROM© within the risk-reduction NCIP has helped develop Value-Based Healthcare and support programme evaluation.
