Long-term outcomes of intestinal penetrating Crohn's disease following successful nonoperative management.

There is a paucity of data on the surgical or medical treatment for abscess/fistula complicating Crohn's disease after successful nonsurgical management. We conducted a cohort study to investigate the long-term outcomes and the risk factors for the requirement of subsequent surgical intervention in Crohn's disease patients with complicating fistulas/abscess following successful nonsurgical management. Data were collected on penetrating Crohn's disease experiencing successful nonsurgical treatment between December 2012 and December 2021. Long-term outcomes and risk factors of surgery were assessed by univariate and multivariate analysis, and subgroup analysis was performed based on penetrating phenotype including abscess, fistula, and phlegmon. A total of 523 penetrating Crohn's disease patients; there were 390, 125, and 60 patients complicated with fistulas, abscess, and phlegmon, respectively. Long-term outcomes showed that BMI < 18.5 (kg/m 2 ), the recurrent abscess, and stricture were independent risk factors of surgery. Biologics and resolution of abscess were independent protective factors of surgery. Furthermore, in 399 patients undergoing early surgery, stricture and BMI < 18.5 (kg/m 2 ) were independent risk factors, and biologics and abscess resolution were protective of the early surgery. Subgroup analysis based on fistula, abscess, and phlegmon phenotype also demonstrated that concomitant stricture was an independent risk factor and the use of biologics was protective of surgical resection. Our data indicate that biologics can delay the requirement of surgery and may be given to patients with penetrating complicating Crohn's disease who have been successfully treated nonoperatively, but surgical resection should be considered in the setting of malnutrition and stenosis formation.

Parapharyngeal and retropharyngeal infections in children: Kawasaki disease needs vigilance.

OBJECTIVE: Kawasaki Disease (KD) may mimic Parapharyngeal (PPI) and Retropharyngeal Infections (RPI), leading to misdiagnosis as Deep Neck Infections (DNIs). The treatment plans for the two diseases are different, and delayed treatment can lead to serious complications. Therefore, prompt diagnosis and management are necessary. This study was performed to evaluate the clinical features of KD mimicking DNIs and explore the treatment options. METHODS: Children with cellulitis or abscess in parapharyngeal or retropharyngeal space in neck CT were included in this study. The medical records of enrolled children were retrospectively reviewed. RESULTS: In total, 56 children were diagnosed with PPI or/and RPI. Twenty-two (39.3%) participants were eventually diagnosed with KD, and 34 (60.7%) were diagnosed with DNIs. Compared with the DNIs group, the KD group had a higher body temperature (p=0.007), and higher levels of AST (p=0.040), ALT (p=0.027), and ESR (p=0.030). Deep cervical cellulitis (p=0.005) were more common in the KD group. However, deep neck abscess often occurred in the DNIs group (p=0.002), with parapharyngeal abscess being the most common type of abscess (p=0.004). The KD mimicking DNIs cases did not respond to antibiotic treatment, but symptoms significantly improved after the use of Immunoglobulin (IVIG) and aspirin. CONCLUSION: Children with KD may exhibit retropharyngeal or parapharyngeal inflammation in the early stages. KD should be considered a differential diagnosis for children with DNIs, high fever, and no response to antibiotic therapy. Surgery in KD mimicking deep neck abscess requires caution.

Modifiable Preoperative Risk Factors to Mitigate Postoperative Site Infection Following Pediatric Gastrostomy.

PURPOSE: There are limited studies assessing modifiable preoperative risk factors for pediatric laparoscopic gastrostomy tubes (LGT) and percutaneous endoscopic gastrostomy (PEG) tubes. We sought to evaluate the effect of demographics and surgical/infectious history on the superficial infection rate following gastrostomy tube (GT) placement. METHODS: After IRB approval, we conducted a single-institution retrospective cohort study from 2015 to 2021 of pediatric patients undergoing LGT or PEG tube. The primary outcome was cellulitis or abscess formation within 30-days and 90-days postoperatively. Statistical analyses were performed with t-tests, Chi-squared, and logistic regression(p ≤ 0.05). RESULTS: There were 382 patients, with 181 (47%) LGT and 201 (53%) PEGs. LGT patients were younger (5.9 vs. 12.3 months, p < 0.001) and more likely to be admitted to the neonatal or cardiac intensive care unit prior to their GT. There were similar rates of prior surgical intervention (58% vs. 66%, p = 0.29) and previous infection (37% vs. 38%, p = 0.87) in both LGT and PEG patients. Within 30-days postoperatively, LGT patients had a higher superficial infection rate (12% vs. 6%, p = 0.04). On multivariate regression, Black race (Odds Ratio 0.10, p = 0.03) was protective and prior Staphylococcus colonization (OR 2.35, p = 0.04) increased the odds of infection. In those patients colonized with Staphylococcus, 21% developed a superficial site infection compared to 9% in those not colonized (p = 0.01). CONCLUSION: These data suggest prior Staphylococcus colonization is a significant risk factor for superficial infection following GT. Further work into preoperative decolonization strategies may provide an avenue to decrease the high infection rate in this common pediatric procedure. LEVEL OF EVIDENCE: Level III.

Perichondritis and auricular cellulitis related to piercings as first manifestation of monkeypox.

INTRODUCTION: Pinna infections are usually due to Staphylococcus aureus infection. It is common for the patient to have had an earring in the area of infection. Monkeypox infection has gone from being an endemic infection to a worldwide health emergency. CASE SUMMARY: In this article we present five cases of monkeypox earring infection of the pinna and what common features we have seen that differentiate them from Staphylococcus aureus infection. DISCUSSION: Symptoms of monkeypox include general malaise, fever with uni- or bilateral lymphadenopathy, and then the appearance within one or two days of skin lesions, we want to alert he otolaryngologist and the medical society to the possibility the diagnostic possibility of monkeypox in patients with an auricular perichondritis.

Incomplete Kawasaki disease presenting with a cellulitis-like plaque: Lessons from an unusual presentation.

Kawasaki disease (KD) is an acute small to medium-vessel vasculitis that primarily affects children under the age of 5 years. The cause of KD is unknown, but it is hypothesized to be a systemic inflammatory illness triggered by infections in genetically predisposed individuals. Diagnosis of incomplete KD is made in patients with prolonged fever without a source who do not meet diagnostic criteria but have some findings consistent with KD such as elevated inflammatory markers, transaminitis, and echocardiographic findings. We present a 7-year-old boy who developed 10 days of fevers and rash that began 3 days after his first dose of hepatitis A vaccination and had notable features of a peculiar cellulitis-like plaque and peripheral eosinophilia.

Tattoo-induced allergic contact dermatitis presents diagnostic challenge as a cellulitis mimic.

Allergic contact dermatitis (ACD) is a prevalent condition associated with numerous potential allergen exposures. Tattoo ink is variable and may contain allergens that can be overlooked in patient education and diagnosis. We present a 27-year-old female with ACD following a new tattoo. The patient was repeatedly misdiagnosed with cellulitis by three different clinicians and treated with multiple antibiotics without improvement. The correct diagnosis was eventually made in the emergency department (ED). Although the patient was aware of her allergies to nickel and cobalt from patch testing, she was not aware of the potential for tattoo ink to contain these allergens because prior tattoos had not provoked an allergic reaction. Consequently, the appropriate care was delayed by a month, resulting in significant morbidity. This case demonstrates the potential for ACD to present similarly to cellulitis in an ED setting and the need for clinical vigilance in diagnosis of ACD. It also highlights the importance of detailed patient education on potential allergen sources particularly in the context of tattooing, which is performed with unregulated and variable ink products.

Textured versus Smooth Tissue Expanders: A Comparison of Complications in 3526 Breast Reconstructions.

BACKGROUND: Increased understanding of breast implant-associated anaplastic large-cell lymphoma has led to a shift away from textured breast devices. A few small studies have compared the complication rates of textured and smooth tissue expanders (TEs). The aim of this study was to compare complication profiles in patients undergoing two-stage postmastectomy breast reconstruction with either textured or smooth TEs. METHODS: The authors performed a retrospective review of female patients who underwent immediate breast reconstruction with textured or smooth TEs from 2018 to 2020 at their institution. Rates of seroma, infection/cellulitis, malposition/rotation, exposure, and TE loss were analyzed in the overall cohort and subgroups undergoing prepectoral and subpectoral TE placement. A propensity score-matched analysis was used to decrease the effects of confounders comparing textured and smooth TEs. RESULTS: The authors analyzed 3526 TEs (1456 textured and 2070 smooth). More frequent use of acellular dermal matrix, SPY angiography, and prepectoral TE placement was noted in the smooth TE cohort ( P < 0.001). Univariate analysis suggested higher rates of infection/cellulitis, malposition/rotation, and exposure in smooth TEs (all P < 0.01). Rates of TE loss did not differ. After propensity matching, no differences were noted in infection or TE loss. Prepectoral smooth expanders had increased rates of malposition/rotation. CONCLUSIONS: TE surface type did not affect rates of TE loss, although increased rates of expander malposition were noted in the smooth prepectoral cohort. Further research is needed to examine breast implant-associated anaplastic large-cell lymphoma risk with temporary textured TE exposure to improve decision-making.

Orbital abscess with white eye in patients treated with oral antibiotics for orbital cellulitis.

PURPOSE: To report a case series of seven patients with late presentation of orbital/subperiosteal abscess following oral treatment of orbital cellulitis. METHODS: A retrospective case series of all patients presented with orbital abscess following oral treatment of orbital cellulitis from two tertiary-care eye centres in Riyadh, Saudi Arabia, was conducted. Demographic profiles, risk factors, initial clinical presentation, management regimens, and final outcome were analysed. RESULTS: Patients presented mainly with proptosis and limitation of extraocular motility without external ophthalmic inflammatory signs. Most patients needed surgical evacuation despite the appropriate initiation of intravenous antibiotics following presentation to our hospitals. CONCLUSION: Treating orbital cellulitis with oral antibiotics may lead to delayed presentation of orbital abscess without external ophthalmic inflammatory signs.

Diabetic Soft Tissue Infections.

Diabetes is a systemic illness that can cause a broad range of physiologic effects. Infection rates and wound healing are both affected through multiple mechanisms. Other physiologic changes increase risk for wounds as well as complex soft tissue infections ranging from simple cellulitis to necrotizing soft tissue infections. Clinicians and surgeons need to have a low index of suspicion for severe infection in a patient presenting with diabetes, and even more so in patients with uncontrolled diabetes.

Celulitis facial por Staphylococcus aureus con metástasis infecciosas y evolución tórpida. Caso pediátrico / Facial cellulitis due to Staphylococcus aureus with metastatic infection and torpid course. A pediatric case report

La bacteriemia por Staphylococcus aureus se define como el aislamiento de dicho germen en al menos un cultivo de sangre. Las metástasis infecciosas se originan por diseminación hematógena y su posterior localización en un sitio distinto al órgano en donde se originó el proceso infeccioso. La prevalencia en la presentación de estos focos infecciosos secundarios es baja en la edad pediátrica, por lo que representa un desafío diagnóstico. Se presenta el caso de un paciente pediátrico con una celulitis facial por Staphylococcus aureus, con metástasis infecciosas y evolución tórpida.

Bacteremia due to Staphylococcus aureus is defined as the isolation of this microorganism in at least one blood culture. A metastatic infection is caused by the hematogenous dissemination and subsequent location of the microorganism in a site other than the one where the infection started. The prevalence of these secondary sources of infection is low in the pediatric population, which is a diagnostic challenge. Here we describe the case of a pediatric patient with facial cellulitis due to Staphylococcus aureus, with metastatic infection and torpid course.

Evaluation of the Risk Factors for Cellulitis among Patients with Peripheral Artery Disease.

Background and objectives: The objective of this study is to elucidate peripheral occlusion artery disease (PAOD) as a risk factor for cellulitis. Materials and Methods: This is a retrospective population-based cohort study. The database is the Longitudinal Health Insurance Database, which covers two million beneficiaries from the entire population of the 2010 registry for beneficiaries in Taiwan. The PAOD group is composed of patients who were newly diagnosed with PAOD from 2001 to 2014. The non-PAOD group is composed of patients who were never diagnosed with PAOD from 2001 to 2015. All patients were followed until the onset of cellulitis, death, or until the end of 2015. Results: Finally, 29,830 patients who were newly diagnosed with PAOD were included in the PAOD group, and 29,830 patients who were never diagnosed with PAOD were included in the non-PAOD group. The incidence densities (ID) of cellulitis were 26.05 (95% CI = 25.31-26.80) patients per 1000 person-years in the PAOD group and 49.10 (95% CI = 48.04-50.19) in the non-PAOD group. The PAOD group had an increased risk of cellulitis (adjusted HR = 1.94, 95% CI = 1.87-2.01) compared to the non-PAOD group. Conclusions: Patients with PAOD were associated with a higher risk of subsequent cellulitis compared to patients without PAOD.

Skin Reactions Following Primary Total Knee Arthroplasty With an Adhesive Superficial Closure System: A Case Series.

BACKGROUND: We investigated a skin adhesive closure device consisting of a self-adhesive polyester mesh placed over the surgical incision, followed by a liquid adhesive that is spread over the mesh and surrounding the skin. It is intended to reduce wound closure times, scarring, and skin complications associated with traditional closure with sutures or staples. The aim of this study was to report on skin reactions in patients who underwent primary total knee arthroplasty (TKA) using the skin adhesive closure system. METHODS: A retrospective review of patients who underwent TKA using adhesive closure between 2016 to 2021 at a single institute was performed. A total of 1,719 cases were analyzed. Patient demographics were collected. The primary outcome was any postoperative skin reaction. Skin reactions were classified as allergic dermatitis, cellulitis, or other. Treatment(s), duration of symptoms, and surgical infections were also collected. RESULTS: A total of 5.0% (86) of patients were found to have any type of skin reaction following their TKA. Of these 86, 39 (2.3%) had symptoms of allergic dermatitis (AD), 23 (1.3%) had symptoms of cellulitis, and 24 (1.4%) had other symptoms. A total of 27 (69%) allergic dermatitis patients were treated with a topical corticosteroid cream only; their symptoms resolved within an average of 25 days. There was only 1 case of superficial infection (<0.001%). No prosthetic joint infections were observed. CONCLUSION: Despite skin reactions appearing in 5.0% of cases, the rate of infection was low. A patient-specific preoperative workup and effective treatment strategies can minimize complications associated with adhesive closure system and increase patient satisfaction following TKA.

[Odontogenic infection as cause of orbital cellulitis]. / Een dentale oorzaak van orbitale cellulitis.

BACKGROUND: Orbital cellulitis is a potentially life-threatening condition. Compression of the optical nerve can cause total or partial loss of vision. Early diagnosis is crucial to prevent complications. In case of a unilateral sinusitis as cause of a unilateral orbital cellulitis complete clinical and dental examination combined with imaging are essential in diagnostics. CASE DESCRIPTION: A 53-year-old man presented with left eye movement impairment, intermittent diplopia and moderate swelling of the left lower eyelid. His diagnosis was post septal orbital cellulitis and despite administration of oral antibiotics no clinical improvement was observed. Orbital imaging by CT could not exclude a dental cause of his unilateral maxillary sinusitis. He was referred to the department of oral and maxillofacial surgery where clinical examination showed a dental cause. After removal of two decayed upper molars a complete recovery was accomplished. CONCLUSION: Odontogenic causes for unilateral orbital cellulitis should always be considered in diagnostics in adults. Clinical presentation and dental examination combined with adequate imaging can confirm the diagnosis.
