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.

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. LEVEL OF EVIDENCE: I.

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.

Phenotypic and molecular characterization and complete genome sequence of a Corynebacterium diphtheriae strain isolated from cutaneous infection in an immunized individual.

Diphtheria is an infectious disease potentially fatal that constitutes a threat to global health security, with possible local and systemic manifestations that result mainly from the production of diphtheria toxin (DT). In the present work, we report a case of infection by Corynebacterium diphtheriae in a cutaneous lesion of a fully immunized individual and provided an analysis of the complete genome of the isolate. The clinical isolate was first identified by MALDI-TOF Mass Spectrometry. The commercial strip system and mPCR performed phenotypic and genotypic characterization, respectively. The antimicrobial susceptibility profile was determined by the disk diffusion method. Additionally, genomic DNA was sequenced and analyzed for species confirmation and sequence type (ST) determination. Detection of resistance and virulence genes was performed by comparisons against ResFinder and VFDB databases. The isolate was identified as a nontoxigenic C. diphtheriae biovar Gravis strain. Its genome presented a size of 2.46 Mbp and a G + C content of 53.5%. Ribosomal Multilocus Sequence Typing (rMLST) allowed the confirmation of species as C. diphtheriae with 100% identity. DDH in silico corroborated this identification. Moreover, MLST analyses revealed that the isolate belongs to ST-536. No resistance genes were predicted or mutations detected in antimicrobial-related genes. On the other hand, virulence genes, mostly involved in iron uptake and adherence, were found. Presently, we provided sufficient clinical data regarding the C. diphtheriae cutaneous infection in addition to the phenotypic and genomic data of the isolate. Our results indicate a possible circulation of ST-536 in Brazil, causing cutaneous infection. Considering that cases of C. diphtheriae infections, as well as diphtheria outbreaks, have still been reported in several regions of the world, studies focusing on taxonomic analyzes and predictions of resistance genes may help to improve the diagnosis and to monitor the propagation of resistant clones. In addition, they can contribute to understanding the association between variation in genetic factors and resistance to antimicrobials.

Whole-genome sequencing and functional annotation of pathogenic Paraconiothyrium brasiliense causing human cellulitis.

BACKGROUND: A pathogenic filamentous fungus causing eyelid cellulitis was isolated from the secretion from a patient's left eyelid, and a phylogenetic analysis based on the rDNA internal transcribed spacer region (ITS) and single-copy gene families identified the isolated strain as Paraconiothyrium brasiliense. The genus Paraconiothyrium contains the major plant pathogenic fungi, and in our study, P. brasiliense was identified for the first time as causing human infection. To comprehensively analyze the pathogenicity, and proteomics of the isolated strain from a genetic perspective, whole-genome sequencing was performed with the Illumina NovaSeq and Oxford Nanopore Technologies platforms, and a bioinformatics analysis was performed with BLAST against genome sequences in various publicly available databases. RESULTS: The genome of P. brasiliense GGX 413 is 39.49 Mb in length, with a 51.2% GC content, and encodes 13,057 protein-coding genes and 181 noncoding RNAs. Functional annotation showed that 592 genes encode virulence factors that are involved in human disease, including 61 lethal virulence factors and 30 hypervirulence factors. Fifty-four of these 592 virulence genes are related to carbohydrate-active enzymes, including 46 genes encoding secretory CAZymes, and 119 associated with peptidases, including 70 genes encoding secretory peptidases, and 27 are involved in secondary metabolite synthesis, including four that are associated with terpenoid metabolism. CONCLUSIONS: This study establishes the genomic resources of P. brasiliense and provides a theoretical basis for future studies of the pathogenic mechanism of its infection of humans, the treatment of the diseases caused, and related research.

Acute cellulitis with Shewanella algae bacteremia.

Shewanella algae are gram-negative bacteria commonly found in aquatic environments. Infections caused by this agent are rarely documented; however, they are increasingly reported, mainly in countries with warm to temperate climates. Herein, we present a case of a 46-year-old immunocompetent woman with acute cellulitis and S. algae bacteremia (the first isolation culture performed at our hospital). To better understand the epidemiology, clinical outcomes, and treatment possibilities for S. algae bacteremia, we searched literature for similar cases; however, we did not find any cases of infections caused by this microorganism reported in Portugal or the Azores.

Complicated Cellulitis is an Independent Predictor for Increased Length of Stay in the Neonatal Intensive Care Unit.

OBJECTIVE: To assess cellulitis in the neonatal intensive care unit (NICU) setting and identify risk factors for its disease severity and whether cellulitis influences length of stay (LOS). STUDY DESIGN: In this retrospective study, patients with cellulitis were identified using the electronic health record while admitted to the NICU at Massachusetts General for Children from January 2007 to December 2020. Demographic and clinical data were extracted from patient records. Two multivariable logistic regression models were constructed to assess for independent predictors for increased LOS (≥30 days) and complicated cellulitis in the hospital. RESULTS: Eighty-four patients met the study criteria; 46.4% were older than 14 days at the time of diagnosis of cellulitis, 61.9% were non-White, and 83.3% were born prematurely; 48.8% had complicated cellulitis as defined by overlying hardware (41.7%), sepsis (7.1%), requirement for broadened antibiotic coverage (7.1%), bacteremia (4.8%), and/or abscess (3.6%). The mean hospital LOS was 58.5 ± 36.1 days SD, with 72.6% having a LOS greater than 30 days. Independent predictors of increased LOS were extreme prematurity (<28 weeks' gestation) (OR: 14.7, P = .03), non-White race (OR: 5.7, P = .03), and complicated cellulitis (OR: 6.4, P = .03). No significant predictors of complicated cellulitis were identified. CONCLUSIONS: This study identifies complicated cellulitis in the NICU as an independent predictor of increased hospital LOS in neonates. Implementation of strategies to mitigate the development of cellulitis may decrease LOS among this high-risk population.

Neurologic and cutaneous infection by Clostridium piliforme in a kitten with systemic Tyzzer disease.

Tyzzer disease (TD) is a highly fatal condition of animals caused by Clostridium piliforme and characterized pathologically by enteritis, hepatitis, myocarditis, and occasionally encephalitis. Cutaneous lesions have been reported only rarely in animals with TD, and infection of the nervous system has not been described in cats, to our knowledge. We describe here neurologic and cutaneous infection by C. piliforme in a shelter kitten with systemic manifestations of TD and coinfection with feline panleukopenia virus. Systemic lesions included necrotizing typhlocolitis, hepatitis, myocarditis, and myeloencephalitis. The cutaneous lesions consisted of intraepidermal pustular dermatitis and folliculitis, with necrosis of keratinocytes and ulceration. Clostridial bacilli were identified within the cytoplasm of keratinocytes by fluorescence in situ hybridization, and a PCR assay was positive for C. piliforme. C. piliforme can infect keratinocytes leading to cutaneous lesions in cats with the location suggesting direct contact with contaminated feces as a route of infection.

Skin infection by Mycobacterium marinum - diagnostic and therapeutic challenge.

The number of skin infections caused by atypical mycobacteria has increased in recent decades. They usually appear after contact with wounds and interruptions in the integrity of the skin. The present report describes a case of cutaneous infection by Mycobacterium marinum, in a young, immunocompetent patient, with a prolonged evolution, diagnosed through a skin lesion culture (from a spindle biopsy of the skin). The patient was treated with multidrug therapy, including clarithromycin, doxycycline, and rifampicin, due to the lesion extent, with satisfactory results. A brief review of the literature is also provided.

Role of systemic corticosteroids in orbital cellulitis: a meta-analysis and literature review / Papel dos corticosteroides sistêmicos na celulite orbitária: uma metanálise e revisão da literatura ,

Abstract Introduction: The standard management of orbital cellulitis is to administer a combination of intravenous broad-spectrum antibiotics along with treatment of associated sinusitis. Objective: The purpose of this study was to evaluate whether the addition of corticosteroids could lead to earlier resolution of inflammation and improve disease outcome. Methods: We independently searched five databases (PubMed, SCOPUS, Embase, the Web of Science, and the Cochrane database) for studies published as recent as December 2019. Of the included studies, we reviewed orbital cellulitis and disease morbidity through lengths of hospitalization, incidence of surgical drainage, periorbital edema, vision, levels or C-reactive protein, and serum WBC levels in order to focus on comparing steroid with antibiotics treated group and only antibiotics treated group. Results: Lengths of hospitalization after admission as diagnosed as orbital cellulitis (SMD = −4.02 [−7.93; −0.12], p -value = 0.04, I2 = 96.9%) decrease in steroid with antibiotics treated group compared to antibiotics only treated group. Incidence of surgical drainage (OR = 0.78 [0.27; 2.23], p -value = 0.64,I2 = 0.0%) was lower in the steroid with antibiotics treated group compared to the antibiotics only treated group. Conclusion: Use of systemic steroids as an adjunct to systemic antibiotic therapy for orbital cellulitis may decrease orbital inflammation with a low risk of exacerbating infection. Based on our analysis, we concluded that early use of steroids for a short period can help shorten hospitalization days and prevent inflammation progression.

Resumo Introdução: O tratamento padrão da celulite orbitária inicia-se com uma combinação de antibióticos intravenosos de amplo espectro concomitante ao tratamento do seio comprometido. Objetivos: O objetivo deste estudo foi avaliar se a adição de corticosteroides poderia levar a uma resolução mais precoce da inflamação e melhorar o desfecho da doença. Método: Fizemos uma pesquisa independente em cinco bancos de dados (PubMed, SCOPUS, Embase, Web of Science e o banco de dados Cochrane) em busca de estudos publicados até dezembro de 2019. Dos estudos incluídos, revisamos a celulite orbitária e a morbidade da doença através dos períodos de internação, incidência de drenagem cirúrgica, edema periorbital, visão, níveis de proteína C-reativa e níveis séricos de leucócitos com foco na comparação do grupo tratado com esteroides e antibióticos e do grupo tratado apenas com antibióticos. Resultados: Os tempos de internação após a admissão dos diagnosticados com celulite orbitária (SMD = -4,02 [-7,93; -0,12], p-valor = 0,04, I2 = 96,9%) diminuíram no grupo tratado com esteroides e antibióticos em comparação ao grupo tratado apenas com antibióticos. A incidência de drenagem cirúrgica (OR = 0,78 [0,27; 2,23], p-valor = 0,64, I2 =0,0%) foi menor no grupo tratado com esteroides e antibióticos em comparação com o grupo tratado apenas com antibióticos. Conclusão: O uso de esteroides sistêmicos como adjuvante da antibioticoterapia sistêmica para celulite orbitária pode diminuir a inflamação orbitária com baixo risco de agravar a infecção. Com base em nossa análise, concluímos que o uso precoce de esteroides por um curto período pode ajudar a encurtar os dias de internação e prevenir a progressão da inflamação.
