What you need to know about common skin problems in older adults.

Skin ageing is a multifaceted process impacted by both intrinsic and extrinsic factors. Drier and less elastic skin with declining sebum levels in older age makes ageing skin more vulnerable to various skin conditions, including infections, inflammatory dermatoses, and cancers. Skin problems are common among older adults due to the effects of ageing, polypharmacy and multimorbidity impacting not only physical health but wellbeing and quality of life. In the UK, older adults in geriatric medicine wards may present with various skin conditions. Hospitalised older individuals may have undiagnosed skin problems unrelated to their admission, making hospitalisation an opportunity to manage unmet needs. Asteatotic eczema, incontinence associated dermatitis, seborrhoeic dermatitis, chronic venous insufficiency, and cellulitis are common disorders clinicians encounter in the geriatric medicine wards. This article outlines the importance of performing comprehensive skin assessments to help diagnose and commence management for these common conditions.

"Demodicosis" Mimicking PreSeptal Cellulitis: Severe Periocular and Facial Inflammation Caused by "Normal" Skin Flora.

Due to their relatively high prevalence and commensalism, the pathogenicity of Demodex mites has been debated. Recent data, however, show Demodex to be associated with skin and ocular surface diseases such as rosacea, blepharitis, and keratitis. Here the authors report the first known case, to the best of the their knowledge, of Demodex infestation mimicking preseptal cellulitis in an adult human. A 29-year-old male bilaterally blind from advanced retinopathy of prematurity presented with a 2-month history of right-greater-than-left upper eyelid and periocular/cheek swelling, redness, and ocular discharge that did not resolve with oral antibiotics or oral steroids. Based on MRI findings, biopsies of the right lacrimal gland, right orbital fat, and right upper eyelid preseptal skin were obtained which revealed marked intrafollicular Demodex mite density and budding yeasts in the upper eyelid skin. This case serves to alert clinicians to this entity that may not otherwise be usually considered in ophthalmic clinical practice.

Validation of Thermal Imaging and the ALT-70 Prediction Model to Differentiate Cellulitis From Pseudocellulitis.

Importance: Cellulitis is misdiagnosed in up to 30% of cases due to mimic conditions termed pseudocellulitis. The resulting overuse of antibiotics is a threat to patient safety and public health. Surface thermal imaging and the ALT-70 (asymmetry, leukocytosis, tachycardia, and age ≥70 years) prediction model have been proposed as tools to help differentiate cellulitis from pseudocellulitis. Objectives: To validate differences in skin surface temperatures between patients with cellulitis and patients with pseudocellulitis, assess the optimal temperature measure and cut point for differentiating cellulitis from pseudocellulitis, and compare the performance of skin surface temperature and the ALT-70 prediction model in differentiating cellulitis from pseudocellulitis. Design, Setting, and Participants: This prospective diagnostic validation study was conducted among patients who presented to the emergency department with acute dermatologic lower extremity symptoms from October 11, 2018, through March 11, 2020. Statistical analysis was performed from July 2020 to March 2021 with additional work conducted in September 2023. Main Outcomes and Measures: Temperature measures for affected and unaffected skin were obtained. Cellulitis vs pseudocellulitis was assessed by a 6-physician, independent consensus review. Differences in temperature measures were compared using the t test. Logistic regression was used to identify the temperature measure and associated cut point with the optimal performance for discriminating between cellulitis and pseudocellulitis. Diagnostic performance characteristics for the ALT-70 prediction model, surface skin temperature, and both combined were also assessed. Results: The final sample included 204 participants (mean [SD] age, 56.6 [16.5] years; 121 men [59.3%]), 92 (45.1%) of whom had a consensus diagnosis of cellulitis. There were statistically significant differences in all skin surface temperature measures (mean temperature, maximum temperature, and gradients) between cellulitis and pseudocellulitis. The maximum temperature of the affected limb for patients with cellulitis was 33.2 °C compared with 31.2 °C for those with pseudocellulitis (difference, 2.0 °C [95% CI, 1.3-2.7 °C]; P < .001). The maximum temperature was the optimal temperature measure with a cut point of 31.2 °C in the affected skin, yielding a mean (SD) negative predictive value of 93.5% (4.7%) and a sensitivity of 96.8% (2.3%). The sensitivity of all 3 measures remained above 90%, while specificity varied considerably (ALT-70, 22.0% [95% CI, 15.8%-28.1%]; maximum temperature of the affected limb, 38.4% [95% CI, 31.7%-45.1%]; combination measure, 53.9% [95% CI, 46.5%-61.2%]). Conclusions and Relevance: In this large diagnostic validation study, significant differences in skin surface temperature measures were observed between cases of cellulitis and cases of pseudocellulitis. Thermal imaging and the ALT-70 both demonstrated high sensitivity, but specificity was improved by combining the 2 measures. These findings support the potential of thermal imaging, alone or in combination with the ALT-70 prediction model, as a diagnostic adjunct that may reduce overdiagnosis of cellulitis.

Cellulitis and bacteremia caused by the fish pathogen,Streptococcus iniae, in an immunocompromised patient: Case report and mini-review of zoonotic disease, lab identification, and antimicrobial susceptibility.

Streptococcus iniae is a fish pathogen that can also infect mammals including dolphins and humans. Its prevalence in farmed fish, particularly tilapia, provides potential for zoonotic infections, as documented by multiple case reports. Systematic clinical data beyond cellulitis for S. iniae infection in humans, including antimicrobial susceptibility data, are unfortunately rare. Here, we present a case of cellulitis progressing to bacteremia caused by Streptococcus iniae in a functionally immunocompromised patient based on CDK4/CDK6 inhibitor and endocrine therapy, and we discuss risk factors, identification, and antimicrobial susceptibility of this rare pathogen.

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.

Necrotising cellulitis of the breast associated with a fungating mucinous adenocarcinoma.

Breast necrotising soft tissue infections (NSTIs) are rare surgical emergencies with limited cases described in the literature. Here, we discuss a unique case of a woman in her 70s who presented with newly diagnosed diabetes and a neglected right breast cancer associated with breast erythema, skin necrosis, crepitus on examination and breast soft tissue gas seen on CT requiring emergent total mastectomy with partial pectoralis muscle excision. Pathology revealed a 15 cm invasive mucinous adenocarcinoma and necrotising polymicrobial cellulitis with a large abscess cavity. She recovered from her surgery with strict glycaemic control and a 10-day course of antibiotics. Multidisciplinary tumour board recommended adjuvant anastrozole, abemaciclib and postmastectomy radiation to complete her oncological treatment. Although exceedingly rare, it is important that clinicians be aware of, promptly recognise and properly treat NSTIs of the breast, as correct care can be life-saving from both infection and malignancy.

Role of Acute Rhinosinusitis in Periorbital Infections in Children.

OBJECTIVE: Periorbital cellulitis in children are commonly caused by acute rhinosinusitis (ARS). This study investigated the association of ARS and the severity of periorbital cellulitis in children. STUDY DESIGN: Retrospective case-control study of children with periorbital cellulitis with ARS versus periorbital cellulitis without ARS. SETTING: Patients were seen at West Virginia University Children's Hospitals between August 2011 to August 2022. METHODS: Patients were divided into cases and controls based on presence or absence of ARS. ARS was defined based on clinical symptoms with objective presence of disease on CT scan. Patients' characteristics, treatment, hospital length of stay, and readmission were collected. RESULTS: The sample consisted of 118 pediatric patients with orbital cellulitis. Patients with ARS were younger than patients without ARS (6.3 vs 8.5, p = 0.025), however there were no sex differences between two groups (p = 0.540). The ARS group had higher incidence of postseptal cellulitis (51.5% vs 9.6%, p < 0.001). As compared to patients without ARS, patients with ARS were more likely to be admitted (p < 0.001), have a longer length of stay (median of 3.5 days vs 0.5 days, p < 0.001), require IV antibiotics (95.3% vs 54.9%, p < 0.001), and require surgical intervention (23.1% vs 5.8%, p < 0.001). Readmission rate was similar between the two groups. CONCLUSION: Children presenting with acute periorbital cellulitis who have ARS tend to have more severe infection requiring higher level of care. ARS should be assessed and incorporated into the plan of care of pediatric patients with periorbital infections.

Clinical diagnosis and outcome of cervicofacial cellulitis in pyrexic rabbits: six cases (2014-2021).

OBJECTIVES: To assess the signalment, history, exam findings, diagnostics, treatment and outcome of rabbits diagnosed with pyrexia and concurrent cervicofacial cellulitis. MATERIALS AND METHODS: Retrospective evaluation of medical records of rabbits diagnosed with cervicofacial cellulitis and pyrexia based on physical exam, contrast-enhanced CT, clinicopathology and microbiology findings. RESULTS: Six out of 1588 rabbits met the study inclusion criteria. Rabbits presented with a median age of 6 years (range, 8 months to 8 years) with a presenting complaint of anorexia or hyporexia. All rabbits had a rectal temperature >40.2°C (104.4°F). Physical exam and contrast-enhanced CT revealed unilateral submandibular and ipsilateral cervical diffuse soft tissue swelling in five of six rabbits. No antemortem evidence of periodontal or dental disease was found on physical exam or CT. Leucopenia was present in five of six rabbits. A left shift with marked toxic changes was present in all four rabbits, for which blood smears were reviewed. Bacterial cultures of the aspirated subcutaneous soft tissue swelling cultured Escherichia coli, Pasteurella multocida, Granulicatella adiacens, Streptococcus species, Haemophilus species and Bacteroides species. Treatment was pursued in five rabbits, where all rabbits received supportive care and four of five rabbits received systemic antibiotics. One rabbit was euthanased following a diagnosis of cervicofacial cellulitis. Three out of five rabbits continued to decline clinically despite medical management, and thus, euthanasia was pursued within 24 hours of starting treatment. Two rabbits responded to initial treatment and developed subsequent multi-focal abscessation. One rabbit was euthanased due to client cost constraints, and one rabbit died shortly after achieving clinical resolution of cervicofacial cellulitis. CLINICAL SIGNIFICANCE: Cervicofacial cellulitis should be considered a differential diagnosis in pyrexic rabbits with facial or cervical swelling with medical and surgical management pursued for therapy.

Diagnosing, assessing and managing cellulitis.

Cellulitis is an acute bacterial infection that affects the deep dermis and surrounding subcutaneous tissue. Although it is a common condition, it is often misdiagnosed because it can mimic a range of conditions that also cause inflamed, red, irritated and painful skin. Such misdiagnoses may lead to unnecessary hospital admissions and antibiotic overuse, with most alternative diagnoses being non-infectious. Undertaking a holistic patient assessment, skin assessment and thorough clinical history is important in the diagnosis of cellulitis, and it is vital to use a collaborative multidisciplinary approach in its acute management and to prevent recurrence. This article defines the term cellulitis and explores its presenting features. The author also discusses the associated risk factors, clinical assessment techniques and effective management strategies, as well as outlining the actions that nurses can take to prevent recurrence.

The critical role of phlebolymphedema in cellulitis associated with lymphedema: Its incidence and economic impact in a large real-world population.

OBJECTIVE: The aims of this study were: to define the incidence of cellulitis in patients with lymphedema (LED) overall and relate this to the etiology of LED; to determine how this rate might be affected by recurrence of cellulitis; and to quantify the contemporary economic burden of treatment. Understanding these factors is essential in developing targeted cellulitis prevention strategies and reducing health care costs. METHODS: The IBM MarketScan Research Database was examined from April 2013 to March 2019 for patients with a new diagnosis of LED (n = 85,601). Based on International Classification of Diseases (ICD)-9/ICD-10 diagnosis codes, the incidence and cost of cellulitis were ascertained during the 3-year follow-up period. Incidence rates (per 100 patient-years [PYs]) and cost (per patient per year) of cellulitis were evaluated among all patients with LED and within subgroups of LED etiologies. RESULTS: Among the three most common morbidities associated with LED (breast cancer-related lymphedema [BCRL], n = 17,954 [20.97%]; gynecological cancer-related LED [GCRL], n = 1256 [1.47%]; and phlebolymphedema [PLED], n = 8406 [9.82%]), rates of cellulitis were markedly lower for BCRL (8.9; 95% confidence interval [CI], 8.7-9.2) and GCRL (14.8; 95% CI, 13.4-16.4) vs PLED (47.7; 95% CI, 46.7-48.8). Patients with a history of cellulitis had markedly higher cellulitis rates during follow-up than those without-overall, 74.0% vs 16.4%; BCRL, 42.9%; 95% CI, 39.7%-46.3% vs 7.6%; 95% CI, 7.3%-7.9%; GCRL, 67.5%; 95% CI, 56.4%-80.8% vs 11.0%; 95% CI, 9.8%-12.4%; and PLED, 81.7%; 95% CI, 79.4%-84.1% vs 30.4%; 95% CI, 29.4%-31.4%, respectively. The mean $/patient/year of cellulitis-related costs for a patient with PLED ($2836; 95% CI, $2395-$3471) was significantly greater than that for BCRL ($503; 95% CI, $212-$1387) and GCRL ($609; 95% CI, $244-$1314). CONCLUSIONS: The incidence of cellulitis associated with LED varies by the etiology of LED. PLED has the highest rates of both an initial cellulitis episode and recurrent cellulitis events. Additionally, PLED has one of the largest cellulitis-related total costs per patient per year. Prevention, as well as early identification and treatment of PLED-associated cellulitis, could significantly decrease health care costs and improve patient quality of life.

[Oto-rhino-laryngological and cervico-maxillofacial pathologies among hospitalized older patients: epidemiological, diagnostical and therapeutical aspects in Lomé, Togo]. / Pathologies ORL et cervico-maxillo-faciales du sujet âgé en hospitalisation : aspects épidémiologiques, diagnostiques et thérapeutiques à Lomé, Togo.

Introduction: In developing countries, 10% of the population is over 60 years old and this proportion is increasing rapidly. The general objective of this study was to describe the profile and management of the elderly subject aged 60 and over, hospitalized in the ENT (Ear, Nose and Throat) and Head/Neck surgery department of the Sylvanus Olympio University Hospital in Lomé, from 2012 to 2021. Method: Retrospective descriptive study. After reviewing the files, selection of patients aged 60 and over, regardless of sex, and hospitalized for an ENT pathology from January 2012 to December 2021. Not included in our study were files of elderly subjects hospitalized but whose age was imprecise, or empty or very incomplete files. Results: A total of 296 cases were included, representing 6.7% of the department's activities. The mean age of the patients was 72 ± 7.3 years with extremes of 60 and 95 years. The age group 6069 years represented 59.5%. The sex ratio M/F was 0.92. Infectious/inflammatory lesions were found in 138 patients (46.6%) including 38.9% of acute cellulitis of dental origin, and tumors were found in 135 patients (45.6%). Tumors were malignant in 59 patients (43.7%) and benign in 76 patients (56.3%). Thyroid was the site of 46 (60.5%) benign lesions and larynx of 29 (49.2%) malignant lesions. Poor oral hygiene, use of non-steroidal anti-inflammatory drugs, diabetes and the combination of smoking and alcohol were the factors favoring the occurrence of acute cellulitis of dental origin in 89.6%, 80.9%, 20.0% and 2.6% of cases respectively (p<0.001). The combination of smoking and alcohol was a factor favoring the occurrence of malignancy in 39% (p<0.001). Surgical treatment was performed in 234 patients (79.1%). With a case lethality rate of 21%, acute cellulitis of dental origin was the leading cause of death (p<0.001). Conclusion: The most frequent pathologies of the ENT sphere in the elderly in our tropical context were infectious and tumoral, largely dominated by acute cellulitis of dental origin, thyroid adenoma and squamous cell carcinoma of the larynx. Despite the tendency to balance infectious and tumoral pathologies, the proportion of acute cellulitis of dental origin remains twice as high as that of malignant tumors. It contrasts with data from other sub-Saharan series where tumoral pathology remains predominant in the elderly. It is important to provide dental care assistance to the elderly and to advocate for the development of geriatrics and access to universal health coverage for the elderly in Togo.

Cellulitis caused by Roseomonas mucosa in a child: a case report.

BACKGROUND: Roseomonas mucosa (R. mucosa) is a pink-pigmented, Gram-negative short rod bacterium. It is isolated from moist environments and skin, resistant to multiple drugs, including broad-spectrum cephalosporins, and a rare cause of infection with limited reports. R. mucosa mostly causes catheter-related bloodstream infections, with even fewer reports of skin and soft tissue infections. CASE PRESENTATION: A 10-year-old boy received topical steroid treatment for sebum-deficient eczema. A few days before the visit, he was bitten by an insect on the front of his right lower leg and scratched it due to itching. The day before the visit, redness, swelling, and mild pain in the same area were observed. Based on his symptoms, he was diagnosed with cellulitis. He was treated with sulfamethoxazole/trimethoprim, and his symptoms improved. Pus culture revealed R. mucosa. CONCLUSIONS: We report a rare case of cellulitis caused by R. mucosa. Infections caused by rare organisms that cause opportunistic infections, such as R. mucosa, should be considered in patients with compromised skin barrier function and regular topical steroid use. Gram stain detection of organisms other than Gram-positive cocci should be considered.

Pseudomonas otitidis bacteremia in an immunocompromised patient with cellulitis: case report and literature review.

BACKGROUND: Pseudomonas otitidis belongs to the genus Pseudomonas and causes various infections, including ear, skin, and soft tissue infections. P. otitidis has a unique susceptibility profile, being susceptible to penicillins and cephalosporins but resistant to carbapenems, due to the production of the metallo-ß-lactamase called POM-1. This revealed genetic similarities with Pseudomonas aeruginosa, which can sometimes lead to misidentification. CASE PRESENTATION: We report the case of a 70-year-old Japanese male who developed cellulitis and bacteremia during chemotherapy for multiple myeloma. He was initially treated with meropenem, but blood culture later revealed gram-negative bacilli identified as P. otitidis using matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). Carbapenem resistance was predicted from previous reports; therefore, we switched to dual therapy with levofloxacin and cefepime, and favorable treatment results were obtained. CONCLUSION: This is the first reported case of P. otitidis cellulitis and bacteremia in an immunocompromised patient. Carbapenems are typically used in immunocompromised patients and P. otitidis is often resistant to it. However, its biochemical properties are similar to those of Pseudomonas aeruginosa; therefore, its accurate identification is critical. In the present study, we rapidly identified P. otitidis using MALDI-TOF MS and switched from carbapenems to an appropriate antimicrobial therapy, resulting in a successful outcome.

Management of Children With Uncomplicated Cellulitis in Emergency and Hospital Settings.

OBJECTIVE: The aim of the study is to establish consensus recommendations on features used to determine the route of antibiotic administration and disposition for children with uncomplicated cellulitis. METHODS: Modified Delphi methodology was performed with 2 rounds of confidential surveys of Emergency medicine and hospital medicine (HM) providers at Lurie Children's Hospital to assess cellulitis management in children (ages 6 months-18 years) without signs of sepsis or abscess formation. Using a 9-point Likert scale, emergency medicine providers ranked features by perceived level of importance when deciding initial antibiotic route and HM providers ranked features on importance when transitioning to oral antibiotics. Responses were grouped as not important (1-3), neutral (4-6), and important (7-9) and re-evaluated in the second round to reach consensus, defined as ≥70% agreement. RESULTS: Emergency medicine providers (n = 17) reached consensus on 15 of 16 features (93.8%), 10 deemed important. Participants reached greatest consensus (100%) on fevers/chills, lymphangitis, and functional impairment as considerations for initiating intravenous antibiotics. HM providers (n = 15) reached consensus on 9 of 11 factors (81.8%), with 7 considered important when deciding on readiness for oral antibiotics. Providers indicated that stability, rather than reduction, of erythematous margins is sufficient to consider transition and de-escalation of therapy at less than 24 hours if all other clinical improvement criteria are met. CONCLUSIONS: This study achieved consensus on important features for treatment and disposition of children with uncomplicated cellulitis in both emergency and inpatient contexts. These features have the potential to aid in decision making and improve standardization of clinical practice.
