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.

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.
METHODS: 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.
CONCLUSIONS: 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.

Non-O1 and non-O139 Vibrio cholerae (NOVC) are serogroups that do not produce cholera toxin and are not responsible for epidemics. Even though rarely encountered in clinical practice, they can cause a spectrum of different conditions ranging from mild gastrointestinal syndrome to extraintestinal diseases, of which bacteremia and wound infections are the most severe. Risk factors for severe disease are cirrhosis, neoplasms, and diabetes mellitus. The mortality rate of NOVC bacteremia in hospitalized patients ranges from 24 to 61.5%. Incidence of NOVC infections is still rare, and consensus recommendations on treatment are not available. We report a case of NOVC bacteremia associated with severe cellulitis in an immunocompetent 75-year-old man who had eaten raw seafood in a location by the northern Adriatic Sea (Italy). Twenty-four hours after intake, he developed a high fever and vomiting. Afterwards, he started noticing the appearance of cellulitis in his right leg, which worsened in a matter of hours. The patient had a history of compensated type 2 diabetes mellitus. NOVC was isolated from both blood cultures and the leg ulcer. The non-O1, non-O139 serogroup was confirmed, and the detection of the cholera toxin gene was negative. Both tests were performed by the Reference National Laboratory of Istituto Superiore di Sanità (ISS). Multiple antimicrobial regimens were administered, with complete recovery. In conclusion, considering the severity of NOVC-associated manifestations, it is of pivotal importance to reach etiological diagnosis for a target antimicrobial therapy and to consider V. cholerae infection in the differential diagnosis in the presence of risk factors and potential exposure.

UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.

Acute bacterial skin and skin-structure infections (ABSSSI) are a significant cause of morbidity in pediatric patients, requiring timely and effective treatment. Dalbavancin, a long-acting lipoglycopeptide antibiotic recently approved for pediatric use, offers advantages such as excellent bactericidal activity against Gram-positive bacteria (including multidrug-resistant pathogens) and high tissue penetration. We present a case series of pediatric patients with ABSSSI treated with dalbavancin. Five cases were described demonstrating the efficacy of dalbavancin in different clinical scenarios. Patients with complex skin conditions, including cellulitis and deep abscesses, benefited from dalbavancin therapy, achieving significant clinical improvement. Notably, dalbavancin facilitated early discharge, improving quality of life and reducing healthcare costs. These cases highlight the potential of dalbavancin as a valuable treatment option for ABSSSI in pediatric patients, particularly in settings where conventional therapies fail to achieve optimal clinical outcomes or prolonged hospitalization is not feasible. Further research is needed to clarify its role and optimize its use in pediatric patients with ABSSSI.

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.
OBJECTIVE: To report cost savings and admission avoidance through first-line intravenous use of dalbavancin for cellulitis in one health board in Wales.
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.

UNASSIGNED: Necrotizing Fasciitis (NF) is a life-threatening, rapidly progressive infection of the skin and underlying soft tissues. Bacterial pathogens induce a toxic-shock reaction that reduces vascular flow, causing thrombosis, sepsis, and tissue necrosis. Treatment consists of immediate IV antibiotics and oftentimes surgical intervention. We present a case of acute NF that was misdiagnosed as cellulitis.
METHODS: A 17-year-old male was transferred to an emergency department from a rural hospital for further management of right lower extremity cellulitis and suspected sepsis. On examination, there was an ulcerated lesion on his right lower leg. Within 4 h, the patient underwent fasciotomy and debridement. The patient was hospitalized for 10 days, received a 3-week-course of Cefazolin, and underwent a meshed split-thickness skin graft. By the end of his hospital stay, he showed significant clinical improvement.
UNASSIGNED: Misdiagnosis of NF will almost always lead to a poorer prognosis. The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score is used to differentiate NF from other soft tissue infections. Yet, other diagnostic clues such as presentation or pain out of proportion to physical findings may be more relevant clinical indicators for a NF diagnosis. Moreover, though imaging findings of NF may be relevant, surgical fascial examination must not be delayed for the purpose of imaging. It is also important to note that cellulitis and NF do share a disease spectrum.
CONCLUSIONS: A life-threatening NF infection may seem to be a benign-appearing case of cellulitis, and thus early detection is vital.
