Celulitis eosinofílica (síndrome de Wells) en una paciente en edad pediátrica / Eosinophilic cellulitis (Wells' syndrome) in a female pediatric patient

El síndrome de Wells o celulitis eosinofílica es una enfermedad inflamatoria de origen desconocido, de aparición infrecuente en la edad pediátrica. Suele manifestarse clínicamente como placas eritematoedematosas, nódulos, pápulas, ampollas, entre otros. Se presenta una paciente en edad pediátrica con nódulos subcutáneos asintomáticos generalizados asociados a eosinofilia grave. El estudio histopatológico de las lesiones fue compatible con celulitis de Wells. Se realizó una evaluación interdisciplinaria en busca de la causa y trastornos eosinofílicos asociados, sin resultados positivos. Se indicó tratamiento sistémico con corticoides y presentó buena respuesta, pero, ante la recidiva de las lesiones tras su suspensión, se indicó dapsona como tratamiento de segunda línea, con mejoría posterior de las lesiones y de la eosinofilia. El objetivo del reporte es presentar una paciente con una manifestación atípica de síndrome de Wells y su desafío terapéutico.

Wells' syndrome, or eosinophilic cellulitis, is an inflammatory disease of unknown origin, uncommon in the pediatric age. It usually appears clinically as erythematous and edematous plaques, nodules, papules, blisters, among other symptoms. Here we describe the case of a female pediatric patient with generalized, asymptomatic subcutaneous nodules associated with severe eosinophilia. The histopathological examination of the lesions was compatible with Wells' syndrome. An interdisciplinary evaluation was performed to establish the cause and look for associated eosinophilic disorders; the results were negative. Systemic corticosteroids were indicated and the patient had a good response; however, in view of the recurrence of the lesions after treatment discontinuation, dapsone was indicated as a second-line treatment, with subsequent improvement of the lesions and eosinophilia. The aim of this report was to describe the case of a female patient with an atypical manifestation of Wells' syndrome and the resulting therapeutic challenge.

A Rare Occurrence of Methicillin-Resistant Staphylococcus aureus (MRSA) Pneumonia Complicated by Nasal Vestibulitis and Orbital Cellulitis: A Case Report.

We report the case of left lower lobe community-acquired methicillin-resistant Staphylococcus aureus (MRSA) pneumonia in an immunocompetent male in his 20s. His illness was complicated by the dramatic appearance of right nasal vestibulitis and right preseptal orbital cellulitis post-admission. The patient responded well to vancomycin and made a complete recovery. Community-acquired MRSA pneumonia in immunocompetent adults is a rare entity in India, and the combination with vestibulitis has not yet been reported. This hitherto unreported presentation sheds further light on the evolving pattern of MRSA infections in the community.

Continuous Ultrasound-Guided Lumbar Erector Spinae Plane Block for Thigh Cellulitis Analgesia: A Case Report.

The management of refractory acute medical pain can be challenging, especially if severe and decompensated systemic pathologies contraindicate neuraxial techniques and deep peripheral blocks. In this case report, we propose a continuous ultrasound-guided lumbar erector spinae plane block (ESPB) for multimodal analgesia of thigh cellulitis. The patient was an 80-year-old male, admitted to the intensive care unit due to septic shock originating from cellulitis of the right lower limb, associated with multiorgan dysfunction. To address refractory pain in the thigh, an ultrasound-guided lumbar ESPB at L3 was performed, with the placement of a perineural catheter and administration of 30 mL of 0.5% ropivacaine, followed by 30 mL boluses of 0.375% ropivacaine every six hours with progressive weaning. The patient maintained controlled pain without the need for rescue analgesia. Continuous ultrasound-guided lumbar ESPB is an effective and safe alternative for thigh analgesia in patients with refractory acute medical pain and systemic pathologies that contraindicate other regional techniques.

Bisphosphonate-Induced Orbital Cellulitis in a Patient With Suspected Parathyroid Carcinoma: A Case Report.

Bisphosphonates are widely used for a number of metabolic bone conditions. Orbital inflammation is a very rare side effect of bisphosphonate therapy that can risk permanent visual loss. We describe the complex case and successful treatment of a 79-year-old man who developed orbital cellulitis following the use of intravenous pamidronate disodium for severe hypercalcaemia. The challenges regarding the diagnosis of parathyroid carcinoma are also discussed.

Prophylactic Antibiotics are Unnecessary for Routine CO2 Laser Burn Scar Treatment.

CO2 ablative fractional laser (CO2 AFL) therapy is a safe and effective procedure when used in the treatment of hypertrophic scars for burn patients. It has a high patient satisfaction rate and a minimal side effect profile, typically consisting of postoperative pain, irritation, surgical site inflammation, and, in rare cases, infection. Although prophylactic antibiotics have historically been recommended, there is a paucity of literature on the topic and recent studies indicate that they may be unnecessary in routine cases. In this retrospective, single center descriptive study, 230 cases in patients with hypertrophic burn scars treated with CO2 AFL therapy were compared. 28 cases were with the use of prophylactic antibiotics and 201 cases were without the use of prophylactic antibiotics. We found that there was no significant association between the use of antibiotics and the prevention of topical skin infection in cases treated with CO2 AFL therapy (p=1). Therefore, we conclude that the omission of prophylactic antibiotics is not associated with an increased risk of infection and recommend that prophylactic antibiotics should not be indicated in the setting of routine CO2 AFL therapy for patients with hypertrophic burn scars.

Wells syndrome following vaccination: A pediatric case with positive patch test to gelatin.

We report a 12-month-old boy with a skin eruption that developed 15 days after receiving the measles, mumps, rubella (MMR), pneumococcal, and meningococcal vaccines, consistent with the diagnosis of Wells syndrome. Patch testing showed a positive reaction to gelatin, which is used as a stabilizer for both live and inactivated vaccines. Gelatin was only present in the MMR vaccine.

Quantitative analysis of the impact of infectious disease physicians on patients in the emergency department fast-track parenteral antibiotics program.

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.

VEXAS syndrome as a cause for multifocal, relapsing head and neck inflammation.

VEXAS syndrome (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) is a novel autoinflammatory syndrome. We describe a case of VEXAS syndrome with upper airway and oral cavity involvement which are not well described in the literature.

Septic embolism due to periorbital cellulitis caused by pimple drainage.

Everyone has used homemade pimple drainage at some point in their lives, particularly in their adolescent and early adult years. However, pimple drainage should always be considered a mild medical procedure, especially in cases where the patient has serious skin diseases. We present the case of a 22-year-old female patient who, in the course of her routine, made a home pimple drainage that resulted in periorbital cellulitis and a septic embolism, despite the fact that these types of clinical cases are uncommon in routine medical practice. This case emphasizes how crucial it is to identify periorbital cellulitis early and treat it appropriately in order to stop a septic embolism from developing.

Radiological differentiation between bacterial orbital cellulitis and invasive fungal sino-orbital infections.

PURPOSE: Invasive fungal orbital infections (IFOI) may be difficult to differentiate from sinogenic bacterial orbital cellulitis (OC). This study investigates the features differentiating OC from IFOI on magnetic resonance imaging (MRI). METHODS: Retrospective study of adult patients with sinogenic OC and IFOI with pre-intervention MRI. Patients without post-septal involvement, non-sinogenic OC (e.g.: secondary to trauma) and poor-quality scans were excluded. Independent Sample's t test and Fisher's exact test were conducted with p < 0.05 deemed statistically significant. RESULTS: Eleven cases each of OC (Mean age: 41.6 ± 18.4 years-old, Male: 10) and IFOI (Mean age: 65.0 ± 16.6 years-old, Male: 9) between 2006 and 2023. IFOI patients were older, more likely immunocompromised and had a lower mean white-cell count (p value = 0.005, 0.035 and 0.017, respectively). The ethmoid and maxillary sinuses were most commonly involved in both entities. Pre-septal and lacrimal gland involvement were more common in OC (p = 0.001 and 0.008, respectively). Infiltrative OC orbital lesions were poorly demarcated, whilst those in IFOI were expansile/mass-like invading the orbit from the adjacent paranasal sinuses. Specific IFOI features included loss-of-contrast-enhancement (LoCE) of paranasal sinus tissues with orbital extension. Extra-orbital and -sinonasal extension indicative of IFOI included contiguous skull base or pterygopalatine fossa involvement, retro-antral and masticator space stranding and vasculitis. CONCLUSION: This study describes the key MRI features of IFOI including differentiating markers from OC. These specific features, such as LoCE of the paranasal and orbital soft tissues, the location and pattern of contiguous soft-tissue involvement, provide expedient identification of IFOI which necessitate early surgical intervention for microbiological confirmation of an invasive fungal pathology.

Cerebritis, optic ischemia, and cavernous sinus thrombosis arising from sinonasal mucormycosis.

Brain and ocular infections can be the worst and fatal consequences of sinonasal infections in immunomodulated or immunocompromised patients. We report a case of a 35-year-old female who received an allogenic hematopoietic stem cell transplantation for acute myeloid leukemia, suffering from maxillo-spheno-ethmoidal rhinosinusitis which was complicated by cavernous sinus thrombosis, orbital cellulitis, optic ischemia and cerebritis.

Demonstrating the benefit of a cellulitis-specific patient reported outcome measure (CELLUPROM©) as part of the National Cellulitis Improvement Programme in Wales.

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.

A Challenging Case of Reactive Angioendotheliomatosis.

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.

Non-O1 and non-O139 Vibrio cholerae Septicemia and Cellulitis: a Case Report.

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.

Odontogenic Orbital Cellulitis at the Crossroads of Surgeries: Multidisciplinary Management and Review.

This article examines two cases of odontogenic orbital cellulitis, highlighting the complexities and interdisciplinary approaches required for effective management. We present two cases and describe the clinical challenges and treatment strategies employed. We report the diagnosis, treatment, and follow-up of patients who developed orbital cellulitis as a complication of an odontogenic infection. Our objective is to report and discuss the clinical aspects and management of this pathology compared to those observed in the literature. This study underscores the necessity for collaboration among various specialties, including ophthalmology, otolaryngology, oral surgery, radiology, and infectious disease, to address the multifaceted challenges posed by this condition. Effective management of orbital abscesses of odontogenic origin requires a timely and multidisciplinary approach for successful outcomes. This article emphasizes the importance of early diagnosis and coordinated care to prevent serious complications, such as vision loss or intracranial infections.

The quality of antimicrobial prescribing in skin and soft tissue management in Australian hospitals: an analysis of the National Antimicrobial Prescribing Survey data.

BACKGROUND: 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 readmission and increased antimicrobial resistance. This study aims to assess the quality of antimicrobial prescribing practices in SSTI management within Australian hospitals to provide guidance for future practice. METHODS: 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. RESULTS: 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 to 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=2,367). From the Surgical NAPS dataset, 5,674 prescriptions for surgical site infections were analysed. 68.2% (n=3,867) were deemed appropriate. The most common reason for inappropriateness was incorrect dose or frequency (27.7%; n=350). CONCLUSIONS: As SSTIs are a common indication for prescribing an antimicrobial in Australian hospitals, identifying effective antimicrobial stewardship strategies to optimise antimicrobial use for SSTI management is therefore recommended to improve patient outcomes.

Assessment of Public Awareness of Cellulitis in Al-Qunfudhah Region, Saudi Arabia.

BACKGROUND: The term "cellulitis" is frequently used to describe a non-necrotizing inflammation of the skin and subcutaneous tissues that is typically caused by an acute infection and does not affect the muscles or fascia. Warmth, erythema, tenderness, swelling, and localized pain are the hallmarks of cellulitis. Life-threatening and debilitating outcomes from cellulitis include necrotizing fasciitis, necrotizing hypodermitis, abscess formation, septic shock, and, in extreme cases, death. The current study aimed to assess public awareness of cellulitis in the Al-Qunfudhah region, Saudi Arabia. METHODS: A descriptive cross-sectional study was conducted targeting all residents in Al-Qunfudhah, Saudi Arabia, during the period from January to March 2024. Data were collected using a pre-structured online questionnaire. The study questionnaire included participants' demographic data, cellulitis data, and knowledge and attitude towards cellulitis. The final questionnaire was uploaded online using social media platforms by the researchers and their friends until no more new participants were included. RESULTS: A total of 470 records were analyzed. Among the respondents, the majority were male (n=347, 73.8%), and the highest proportion fell within the age range of 18 to 25 years (n=174, 37.0%). The highest proportion of respondents correctly identified cellulitis as a medical condition affecting the skin and soft tissues underneath it, typically caused by infection or injury (n=278, 59.1%). Additionally, the majority acknowledged that cellulitis can cause pain, swelling, and redness in the affected area (n=240, 51.1%). As for factors associated with awareness of cellulitis, significant associations were found with age group (p=0.031), educational levels (p=0.003), and employment status (p=0.002). CONCLUSIONS: This study revealed a high level of awareness of cellulitis among participants, especially highly educated and employed participants. Participants believed that healthcare providers play a crucial role in raising population awareness of cellulitis health problems.

Chronic Cellulitis in the Unhoused: Case Study and Treatment Considerations.

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.
