Rhino-Orbital Cerebral Mucormycosis in a Healthy Female Child: Case Report.

Mucormycosis is a potentially fatal condition with a high mortality rate, particularly when there is extra nasal involvement, and it is rare for patients with fungal brain disease to survive. It mostly affects patients who are metabolically or immunologically compromised, which constitutes one of the three classical stages of the progression of Rhino-Orbito-Cerebral Mucormycosis (ROCM). Stage I: infection of the nasal mucosa and paranasal sinuses; Stage II: orbital involvement; Stage III: cerebral involvement.Here, we report a case of rhino-orbital cerebral mucormycosis in a 14-year-old girl with no known risk factor who presented with periorbital edema, right eye proptosis, fever, and extreme facial pain, which progressively worsened to confusion and left leg weakness in 3 days after admission. The final diagnosis was rhino-orbital-cerebral mucormycosis. The infection was successfully treated using liposomal amphotericin and surgical debridement to remove infected orbital tissue. Mucormycosis is a potentially fatal disease that necessitates prompt diagnosis and treatment. Children are rarely infected with mucormycosis. The majority of studies show that people are typically between 40 and 50 years old. ROCM is typically diagnosed using clinical symptoms and histopathologic evaluation; however, imaging is critical in determining the presence of intracranial lesions. The standard treatment for ROCM is amphotericin B at a recommended dose of 1.0-1.5 mg/kg/day for weeks or months, depending on the clinical response and severity of adverse drug reactions, particularly nephrotoxicity.Rhino-orbital cerebral mucormycosis in a healthy female child is uncommon; early diagnosis and prompt treatment with Amphotericin B should be necessary. Devastating consequences will result from a delayed diagnosis.

Acute Paraplegia Caused by Spinal Epidural Empyema Following Infectious Cellulitis of the Hand: Case Report and Literature Review.

Background Spinal epidural abscess is a rare but serious condition that can cause spinal cord compression and neurological deficits. Case Description and Methods The article reports a case of a 31-year-old patient who presented with an infectious cellulitis in the left hand, which progressed to a spinal epidural abscess. The diagnosis was confirmed by clinical examination and magnetic resonance imaging. Treatment involved laminectomy, after which the patient had complete recovery of neurological deficits. This article is a case report with a literature review. Patient data and images were collected by the researchers who participated in the patient's care. The literature was reviewed by one of the researchers based on the search for articles in the PubMed database. For the research, the following keywords were inserted: "Spinal epidural empyema," "Spinal epidural abscess." Conclusion Spinal epidural abscess is often underdiagnosed, which can lead to delays in treatment and serious complications. The relationship between cellulitis and spinal epidural abscess may be related to the spread of infection through the lymphatic or blood system.

Severe cellulitis from methicillin-resistant Staphylococcus aureus (MRSA) in a couple of preterm twins: a case report.

BACKGROUND: Preterms are at risk of systemic infections as the barrier function of their immature skin is insufficient. The long period of hospitalization and the huge number of invasive procedures represent a risk factor for complications. Among the nosocomial infections of the skin, methicillin-resistant Staphylococcus aureus (MRSA) is associated with significant morbidity and mortality. We report a clinical case of cellulitis and abscess in two preterm twins caused by MRSA in a tertiary level Neonatal Intensive Care Unit (NICU). CASE PRESENTATION: Two preterm female babies developed cellulitis from MRSA within the first month of extrauterine life. The first one (BW 990 g) showed signs of clinical instability 4 days before the detection of a hyperaemic and painful mass on the thorax. The second one (BW 1240 g) showed signs of clinical instability contextually to the detection of an erythematous, oedematous and painful area in the right submandibular space. In both cases the diagnosis of cellulitis was confirmed by ultrasound. A broad spectrum, multidrug antimicrobial therapy was administered till complete resolution. CONCLUSIONS: Due to the characteristic antibiotic resistance of MRSA and the potential complications of those infections in such delicate patients, basic prevention measures still represent the key to avoid the spreading of neonatal MRSA infections in NICUs, which include hand hygiene and strict precautions, as well as screening of patients for MRSA on admission and during hospital stay, routine prophylactic topical antibiotic of patients, enhanced environmental cleaning, cohorting and isolation of positive patients, barrier precautions, avoidance of ward crowding, and, in some units, surveillance, education and decolonization of healthcare workers and visiting parents.

Outcomes from a proof-of-concept specialist lymphoedema clinic in the community.

The Health and Safety Execultive lymphoedema model of care was published in 2018 highlighting the lack of dedicated lymphoedema services in Ireland. This led to the introduction of a proof-of-concept primary care specialist lymphoedema clinic. The clinic was responsible for all patients from their county. A comprehensive dataset was gathered which included the patient's history for 1 year prior to their presentation at clinic and then 6 monthly. A quality of life tool (LymQoL) and a patient satisfaction survey were completed. Completed 1-year data showed a significant reduction in GP and public health nurse visits as well as a reduction in the occurrence of cellulitis and associated hospital admissions. All areas of quality of life were improved and patient satisfaction was either excellent (89%) or very good (11%). The 1-year findings strongly support the roll-out of specialist clinics to all regional health areas.

Development of real-time PCR assay for quantitative detection of Clostridium septicum.

Cellulitis is an important disease in commercial turkey farms associated with significant economic loss. Although the etiology of cellulitis is not fully elucidated, Clostridium septicum (C. septicum) is one of the main causes of this infectious disease. In this study, we report the development of a quantitative real-time PCR (qRT PCR) assay targeting the alpha-toxin gene (csa), which involves a prior 15-cyle PCR using a nested pair of primers to increase the detection sensitivity. Additionally, the TaqMan probe was employed to increase the target-specificity of the assay. The performance of our nested qRT-PCR assay was evaluated using Clostridium isolates from turkey farms, representing both septicum and non-septicum species, as well as sponge swab samples from turkey farms. Our step-by-step development of the assay showed that the csa gene is a suitable target for specific detection of C. septicum strains and that the inclusion of nested PCR step significantly increased the detection sensitivity of the final qRT PCR assay. The performance of the assay was also validated by a high correlation of the threshold cycle numbers of the qRT PCR assay with the relative abundance of C. septicum read counts in 16S rRNA gene microbiota profiles of the C. septicum-containing samples from turkey farms.

Molecular characterization of Escherichia coli isolates recovered from broilers with cellulitis.

Avian cellulitis in broilers, caused by avian pathogenic Escherichia coli, is a major cause for carcass rejections during meat inspection, resulting in significant economic losses. In this study, we analysed E. coli isolates obtained from broiler chickens affected by cellulitis for their genetic relatedness and antimicrobial resistance phenotype and genotype. The objective was to determine whether there is a clonal spread or whether these clinical isolates differ. For this purpose, E. coli was isolated from swab samples collected from diseased broilers across 77 poultry farms in Germany, resulting in 107 isolates. These isolates were subjected to serotyping, PCR-based phylotyping and macrorestriction analysis with subsequent pulsed-field gel-electrophoresis for typing purposes. In addition, the presence of virulence genes associated with avian pathogenic E. coli (APEC) was investigated by PCR. Antimicrobial susceptibility of the isolates was examined by the disk diffusion method according to CLSI guidelines and subsequently, the presence of corresponding resistance genes was investigated by PCR. Typing results revealed that a significant proportion of the isolates belonged to serotype O78:K80, which is one of the major APEC serotypes. Phylogenetic grouping showed that phylogenetic group D was most commonly represented (n = 49). Macrorestriction analysis showed overall heterogenous results, however, some clustering of closely related isolates was observed. The level of antimicrobial resistance was high, with 83.8% of isolates non-susceptible to at least one class of antimicrobial agents and 40% of isolates showing resistance to at least three classes. The most frequently observed resistance was to ampicillin, mediated by blaTEM (n = 56). However, few isolates were non-susceptible to ciprofloxacin (n = 8) and none of the isolates was resistant to 3rd generation cephalosporins or carbapenems. Overall, the results show that genetically diverse APEC associated with avian cellulitis can be found among and within German poultry farms. While most isolates were antimicrobial resistant, resistance levels to high(est) priority critically important antimicrobials were low.

Systemic Lupus Erythematosus and Lupus Nephritis Presenting as Severe Constitutional Symptoms.

Systemic lupus erythematosus (SLE) is a remitting-relapsing systemic autoantibody and immune complex disease with a similar clinical presentation to that of malignancy and infection. The authors report a case of newly diagnosed SLE and lupus nephritis in a 48-year-old woman with constitutional symptoms and unintentional weight loss. Her presentation was further complicated by pericardial effusion and methicillin-resistant Staphylococcus aureus (MRSA) facial cellulitis and bacteremia. In the context of nonspecific symptoms and a wide initial differential diagnosis, the early consideration of rheumatologic etiologies and the involvement of consultant services led to appropriate diagnostic testing and a timely diagnosis.

Systemic therapy for psoriasis and the risk of cutaneous infections.

Systemic treatments are important for patients with moderate-to-severe psoriasis; however, they may occasionally cause adverse infectious events. Although the risk of severe infections with psoriatic treatments is well established, little is known about cutaneous infections. Therefore, we studied the frequency of cutaneous infections in patients with psoriasis who underwent biologic treatment. A total of 878 patients (237 females and 641 males) were analyzed in this follow-up survey conducted in 2020 and based on the Western Japan Psoriasis Registry. The observed skin phenotypes were psoriasis vulgaris (83.3%), pustular psoriasis (7.5%), and psoriatic arthritis (28.9%). The most frequently prescribed systemic drug was apremilast (11.3%), followed by ixekizumab (11.0%), risankizumab (10.9%), and secukinumab (10.4%). The incidence of cutaneous bacterial infections was 12 (1.37% of the total patients), with cellulitis being the most common (8/12, 67%). The incidence of viral infections was 11 (1.25%) including the most common, herpes zoster (9/11, 82%); and that of fungal infections was 45 (5.13%) including 33 (73%) and seven (16%) patients with trichophytosis and oral candidiasis, respectively. Multivariate analysis revealed that cutaneous bacterial infections were frequently observed in patients receiving tumor necrosis factor-α (odds raio [OR] 9.917, 95% confidence interval [CI] 2.069-47.572, p = 0.004) and interleukin (IL)-17 (OR 10.798, 95% CI 2.35-49.616, p = 0.002) inhibitor treatments. A history of otitis media and treatment with oral medications (OR 4.50, 95% CI 1.281-15.804, p = 0.019 and OR 3.80, 95% CI 1.141-12.679, p = 0.03 respectively) were associated with a higher ORs for cutaneous viral infections. Furthermore, age and use of IL-17 inhibitors were associated with elevated ORs for fungal infections. In conclusion, our study reveals that systemic therapies may increase the risk of cutaneous viral infections. Therefore, dermatologists should exercise caution in this regard.

Qualitative and Quantitative Magnetic Resonance Imaging in Bacterial Orbital Cellulitis.

PURPOSE: To summarise the qualitative and quantitative parameters of bacterial orbital cellulitis (OC) on magnetic resonance imaging (MRI) and explore their clinical correlations. METHODS: Multi-centre retrospective study with inclusion of patients of all ages with OC who underwent MRI. Patients with isolated pre-septal cellulitis, bilateral disease and poor-quality scans were excluded. An enlargement ratio for extraocular muscles (EOMs) was calculated by dividing maximal EOM measurements from the affected side by the contralateral side. RESULTS: Twenty MRI scans from twenty patients (Mean age: 40.8 ± 24.3 years old, M: F = 15:5) between 2011 and 2022 were analysed. Three (15.0%) cases were paediatric patients (<18 years old). All cases had both pre-septal and orbital fat involvement. The EOM were affected in nineteen cases, with the superior muscle complex (18/19, 94.7%) most commonly affected. Mean enlargement ratio (1.30, Range: 1.04-1.82) was greatest for the medial rectus on axial views on T1 and fat-suppressed contrast-enhanced T1 (FS CE T1). Optic peri-neuritis was present in eleven (55.0%) patients, whilst two (9.5%) cases had optic neuritis. A greater degree of proptosis was observed in patients with optic neuropathy and those who underwent surgical intervention compared to those without (p = .002 and p = .002, respectively). CONCLUSION: MRI remains an important imaging modality for evaluating complicated OC. However, qualitative features may lack accuracy and is not a reproducible means of analysis. Simple quantitative parameters, such as proptosis and EOM measurements, correlate with high-risk clinical features and may have utility in predicting clinical course.

Severe Shewanella Cellulitis Following Saltwater Exposure in an Elderly Patient.

Shewanella algae is an opportunistic Gram-negative bacillus primarily found in marine environments. It can cause a range of infections in humans, from superficial soft tissue infections to more severe conditions like bacteremia, otitis, and hepatobiliary infections. While infections are rare, they can be significant, leading to complications such as sepsis and tissue necrosis. We present the case of severe cellulitis caused by Shewanella in an 88-year-old patient with multiple comorbidities. Following a blue crab pinch and consequent saltwater exposure, the patient developed severe cellulitis, sepsis, delirium, and atrial fibrillation. Despite these complications and the patient's age, a prompt diagnosis and a combination of antibiotic treatments led to a successful recovery. This case is notable for its illustration of the potential severity and diverse clinical presentation of Shewanella infections. It highlights the importance of considering Shewanella as a possible pathogen in cases of saltwater exposure and teaches management in elderly, multi-morbid patients.

Facial Cellulitis and Skin Abscess: A Case of a Simple Bone Cyst in the Mandibular Bone.

Cellulitis, abscess, or both are among the most common skin and soft tissue infections. Typically, cellulitis arises due to bacterial penetration through breaches in the skin's protective barrier. However, in cases of facial cellulitis, it is necessary to consider not only the breakdown of the skin barrier but also to differentiate odontogenic cellulitis. A prompt and accurate diagnosis of facial infections stemming from dental issues, coupled with the administration of antibiotics and dental interventions, played a crucial role in resolving this condition. Odontogenic cellulitis often develops as a result of dental caries. However, we experienced a case of odontogenic cellulitis and skin abscess occurring due to a simple bone cyst in the mandible, even in the absence of dental caries. Proper imaging examinations are crucial for diagnosis.

Sarcoid-like reaction of the orbit in diffuse large B-cell lymphoma.

Sarcoid-like reaction (SLR) has been reported in patients with solid tumor malignancies, lymphomas, and patients receiving immunotherapy. SLR is often incidentally found during positron emission tomography/computed tomography scans as hilar and/or mediastinal lymphadenopathy. SLR has also been found in the lung, spleen, bone marrow, and skin. Biopsy of these lesions shows noncaseating granulomas. When systemic criteria are not met for sarcoidosis, these noncaseating granulomas are termed SLR. We present the first case in the literature of a case of orbital SLR in a patient with concomitant diffuse large B-cell lymphoma and inverted papilloma of the maxillary sinus. This case highlights the importance of including malignancy in the differential for the presence of a noncaseating granuloma in the orbit.

Effectiveness of antibiotic therapy for early recurrence of peritonsillar cellulitis and abscesses: A retrospective cohort study.

OBJECTIVE: Short-term recurrence is common in patients with peritonsillar cellulitis and abscesses, leading to socioeconomic problems. Early switching from intravenous to oral antibiotics is feasible for treating certain diseases. However, reports on early switching and total antibiotic administration duration in peritonsillar cellulitis and abscesses are limited. This study aimed to determine the appropriate antibiotic therapy duration and examine the impact of early oral switch therapy on peritonsillar cellulitis and abscesses. METHODS: We retrospectively identified 98,394 patients who received antibiotic therapy during hospitalization for peritonsillar cellulitis and abscesses between July 1, 2010, and December 31, 2019, using the Japanese Diagnosis Procedure Combination database. RESULTS: Propensity score matching analysis revealed no significant between-group difference in the rehospitalization rate (early oral switch therapy and long intravenous therapy: 1.7 % [198 of 11,621] vs. 2.0 % [234 of 11,621], odds ratio [OR] 0.84, 95 % confidence interval [CI] 0.70-1.02). A long total duration of antibiotic therapy (reference: 1-9 days) was associated with a low risk of rehospitalization (10-14 days: OR 0.86, 95 % CI 0.78-0.95; 15+ days: OR 0.51, 95 % CI 0.38-0.66). CONCLUSION: Early oral switch therapy may be a viable option for treating patients with peritonsillar cellulitis and abscesses in good condition who can tolerate oral intake. No less than 10 days of antibiotic therapy is desirable.

Regional odontodysplasia with facial cellulitis: a case report and literature review.

Regional odontodysplasia (ROD) is a localized developmental anomaly involving deciduous and permanent dentition, with a significant impact on patients. The affected teeth display unique ghost-like radiological characteristics, clinically manifesting as delayed tooth eruption, abnormal tooth morphology, and recurrent swelling of gingiva. In this paper, we report a case of a 2-year-old patient with ROD whose chief complaint was facial cellulitis. We analyze the medical history, clinical examination, radiographic findings, and histologic findings, and review the pathological features, pathogenesis, multidisciplinary diagnosis, and treatment of ROD. This rare case, which offers clinical samples for its further study, can provide a deeper study of ROD.

Significantly reduced duration of antibiotic prescription for erysipelas subsequent to the 2019 French guidelines on skin and soft tissue infection: A before-after study.

BACKGROUND: New skin and soft tissue infections (SSTI) guidelines were published in 2019 in France, changing the recommended duration for antibiotic treatment. The objective of the present study was to assess the impact of the publication of the 2019 French guidelines on SSTIs on the duration of antibiotic prescription for erysipelas. METHODS: In a before-after study (a year before and a year after April 1st, 2019), we included all adult patients diagnosed with erysipelas in Reims University Hospital medical wards and the emergency department. We retrospectively retrieved antibiotic prescription duration in the patients' medical files. RESULTS: Among 50 patients in the "before" and 39 in the "after" group, the mean duration of antibiotic prescription was significantly shorter in the "after" group (9.4 ± 2.8 vs. 12.4 ± 3.8 days, p = 0.0001). CONCLUSIONS: A 25% decrease in the duration of antibiotic prescription for erysipelas was observed following the implementation of these guidelines, providing useful information for an antibiotic stewardship policy.

Osteomyelitis Masquerading as Cellulitis: A Case Report.

Osteomyelitis, a significant global healthcare issue, often results from infections related to open fractures, surgery, or conditions like diabetic foot ulcers. This report describes a case of osteomyelitis in a 62-year-old female with various pre-existing health conditions. The patient initially presented with swelling, pain, and difficulty walking in the right lower extremity, accompanied by systemic symptoms. Despite an initial diagnosis of cellulitis and treatment with ceftriaxone, a subsequent CT scan revealed a pretibial abscess and confirmed osteomyelitis caused by pan-sensitive Escherichia coli. Surgical debridement was performed, and the patient received six weeks of intravenous antibiotics. Hence, a heightened level of suspicion is essential to facilitate a timely diagnosis of osteomyelitis and enhance long-term prognosis. The case underscores the importance of a multidisciplinary approach, including meticulous surgical intervention and tailored antimicrobial therapy, in achieving positive outcomes for osteomyelitis patients.

Labial Necrotizing Fasciitis Caused by Pelvic Eggerthia catenaformis Infection.

A patient with comorbid diabetes mellitus, obesity, and hypertension acutely presented to the ED due to labial cellulitis with rapidly progressing symptoms of systemic inflammation. Clinical examination revealed fever and groin pain that was tender to palpation. Initial contrast-enhanced CT scans showed labial cellulitis extending to the inguinal canal, with later CT imaging findings of subcutaneous air indicative of necrotizing fasciitis (NF). Antimicrobial therapy was initiated empirically and later tailored to culture antibiogram. The patient underwent acute surgical abscess drainage and tissue debridement but was transferred to the surgical intensive care unit (SICU) due to postoperative blood loss and hypotension. Two additional surgical procedures were needed before sufficient drainage was achieved, and Eggerthia catenaformis (E. catenaformis) was isolated from all samples. Due to the extent of the infection, the patient was admitted for a total of 16 days, with five days spent in the SICU. They recovered completely due to adequate surgery and antimicrobial therapy for a total of 24 days. Here, we present the third reported case of NF due to E. catenaformiswhile emphasizing timely treatment with empiric antibiotics and surgical intervention.

A Case Report of Pseudomonas Infection in a Patient With Nasal Septum Perforation, Cocaine Use Disorder, and a Perinuclear Anti-neutrophil Cytoplasmic Antibody (p-ANCA)-Positive Assay.

Nasal septum perforation (NSP) occurs secondary to many underlying etiologies, including facial trauma, drug use, malignancy, infection, or autoimmune disease. We present the case of a 39-year-old female with a past medical history of cocaine use disorder who presented with symptoms concerning facial cellulitis unresponsive to antibiotic therapy. Physical exam and subsequent imaging revealed the presence of NSP. The patient underwent a full workup exploring potential etiologies of NSP in the setting of cocaine use disorder, with lab results indicating Pseudomonas aeruginosa and Pseudomonas putida cellulitis as well as a positive perinuclear anti-neutrophil cytoplasmic antibody (p-ANCA) assay. This case highlights the importance of maintaining a broad differential diagnosis for the etiology of NSP and avoiding anchoring bias.
