Challenges In Diagnosing Staphylococcal Scalded Skin Syndrome In Children With Kwashiorkor: A Case Report, Christie Hamdali, Sondang Sirait, Adria Rusvita, Bawono Bhakti

Journal of General - Procedural Dermatology & Venereology Indonesia

Staphylococcal scalded skin syndrome (SSSS) is a type of exfoliating skin disease with high incidence in children. This condition can cause serious morbidity and even mortality with certain comorbid diseases such as malnutrition. Malnutrition could mask the diagnosis of SSSS because of its similarity to numerous differential diagnoses. Accuracy of clinical diagnosis is then essential to determine the proper initial management. This case report presents a 6-month-old male baby with staphylococcal scalded skin syndrome and kwashiorkor. The patient presented with complaints of multiple erythematous plaques and widespread vesicular lesions that subsequently ruptured, resulting in erosions. Physical examination revealed edema, coarse …

A Novel Gardnerella, Prevotella, And Lactobacillus Standard That Improves Accuracy In Quantifying Bacterial Burden In Vaginal Microbial Communities, Jacob H. Elnaggar, Caleb M.

Bacterial vaginosis (BV) is the most common vaginal dysbiosis. In this condition, a polymicrobial biofilm develops on vaginal epithelial cells. Accurately quantifying the bacterial burden of the BV biofilm is necessary to further our understanding of BV pathogenesis. Historically, the standard for calculating total bacterial burden of the BV biofilm has been based on quantifying Escherichia coli 16S rRNA gene copy number. However, E. coli is improper for measuring the bacterial burden of this unique micro-environment. Here, we propose a novel qPCR standard to quantify bacterial burden in vaginal microbial communities, from an optimal state to a mature BV biofilm. …

Posttreatment Lyme Disease Syndrome And Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: A Systematic Review And Comparison Of Pathogenesis, Natalie Bai, Christie Richardson

Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship

Lyme disease is the most common vector-borne illness in the United States and has been causing significant morbidity since its discovery in 1977. It is well-documented that about 10% of patients properly treated with antibiotics never fully recover, but instead go on to develop a chronic illness dubbed, posttreatment Lyme disease syndrome (PTLDS) characterized by severe fatigue, cognitive slowing, chronic pain, and sleep difficulties. This review includes 18 studies that detail the symptoms of patients with PTLDS and uses qualitative analysis to compare them to myalgic encephalitis/chronic fatigue syndrome (ME/CFS), a strikingly similar syndrome. In the majority of the PTLDS …

Stewardship Opportunities For Cervical Lymphadenitis And Deep Neck Space Abscesses, Aaron Shaw, Brian R. Lee, Lauren Kazmaier, Emily Baker, Tina Dao, Sandra Arnold, Angela Myers

Research Days

Background: Cervical lymphadenitis (LAD) and deep neck space abscesses (DNSA) are common pediatric infections caused by similar bacteria. We sought to determine differences in presentation, diagnosis, and treatment between LAD and DNSA to identify antimicrobial and diagnostic stewardship opportunities.

Methods: Charts were obtained using ICD9/10 codes for retropharyngeal and parapharyngeal abscessed (DNSA), and LAD between 1/1/10-12/31/20 from two pediatric centers. 1981 charts were identified. Charts were excluded if the diagnosis was not a bacterial infection (e.g. Kawasaki disease), if the LAD was not in the neck, or if caused by less common bacteria (e.g. tuberculosis). Data on presenting signs, symptoms, …

Elucidating The Impact Of Sos-Response Timing In On Escherichia Coli Survival Following Treatment With Fluoroquinolone Topoisomerase Inhibitors, Stephanie Schofield

Honors Scholar Theses

Antibiotic treatment failure is a public health crisis, with a 2019 report stating that roughly 35,000 deaths occur in the United States yearly due to bacterial infections that are unresponsive to antibiotics (1). One complication in the treatment of bacterial infection is antibiotic persistence which further compromises our battle to effectively treat infection. Bacterial persisters can exist in clonal bacterial cultures and can tolerate antibiotic treatment by undergoing reversible phenotypic changes. They can survive drug concentrations that their genetically identical kin cannot. Some persisters remain in a slow growing state and are difficult to target with current antibiotics. A specific …

The Angiovac® Device Limits Lethal Complications Of Sepsis And Severe Infective Endocarditis With A Large Tricuspid Valve Vegetation: A Case Report, Dua Xiao, Raeann Dalton, Adam Fineman, Michael Benz, Antonios Tsompanidis

Rowan-Virtua Research Day

Introduction: Infectious endocarditis of the tricuspid valve is a common complication of intravenous drug use. Endocarditis caused by viridans streptococci can lead to heart valve vegetations which may be life threatening due to the potential for embolism and obstruction. Management of large valvular vegetations is often difficult due to the risks involved with open heart surgery, especially in patients with comorbid conditions. The AngioVac® device has been shown in rare cases to be effective at debulking vegetations without the need for invasive surgery.

Case Presentation: We present a patient with a history of intravenous heroin use disorder, hepatitis C, spinal …

The Vaginal Microbiome Post-Menopause And Urinary Tract Infections, Rifke Anolik, Julia Kiffel, Venkateswar Venkataman

Rowan-Virtua Research Day

Background: Urinary Tract Infection (UTI) is a condition where pathogens invade the urinary tract and can travel up the urethra and into the bladder. UTIs occur more commonly in females compared to males and in the post-menopausal population this rate increases significantly. While these infections may be asymptomatic, they can also cause severe discomfort and lead to serious and even life threatening complications. Recent investigation into the vaginal microbiome has opened the doors to a possible mechanism behind the increased incidence of UTIs after menopause. Understanding the pathogenesis behind the increased risk of UTIs in the postmenopausal state will allow …

When Constipation Becomes Lethal: Septic Shock Induced By Stercoral Colitis In A 77-Year-Old Female, Anna Delancy, Nicholas Tomasello, Joan Wiley, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Stercoral colitis is a form of colitis caused by fecal impaction distending the colon and causing fecaloma formation. Fecalomas lead to pressure necrosis of the colon and eventual perforation. The increased intraluminal pressure from the distention of the colon causes vascular compromise and ischemia. The most common locations of necrosis are in the sigmoid colon and rectum . When progressed to perforation, the mortality rate is as high as 60%. The most common cases of stercoral colitis occur in nursing home patients, mentally impaired patients, or those with chronic constipation. Here we describe an unusual case of stercoral colitis causing …

Characterization Of Antibiotic Susceptibility Profiles Of Extensively- And Pan-Drug Resistant Acinetobacter Baumannii Clinical Isolates, Rachel Carr, Justin Halim, Rebecca Fliorent, Henry Fraimow, Dejan Nikolic, Valerie Carabetta

Rowan-Virtua Research Day

Acinetobacter baumannii is an opportunistic pathogen common in intensive care units (ICUs), particularly among immunocompromised individuals. Nosocomial A. baumannii infections have become increasingly problematic in recent years, as these bacteria rapidly acquire antibiotic resistance, leading to the emergence of multidrug, extensively drug and pan drug-resistant (MDR, XDR, and PDR, respectively) isolates. Recently, Cooper University Hospital (CUH) experienced a large increase in highly drug-resistant A. baumannii infections, which had a mortality rate of 60%. Oftentimes, physicians had to turn to combinations of drugs with no experimental verification or historically shelved antibiotics, such as the polymyxins, in a desperate attempt to save …

Handheld Bedside Pocus In The Evaluation Of Neck Swelling: A Case Of Ludwig's Angina, Alex Gechlik, Frank Wheeler, James Espinosa, Alan Lucerna, Henry Schuitema

Rowan-Virtua Research Day

Ludwig's angina is a rare and life threatening cellulitic infection, first described by German physician, Wilhelm Frederick Von Ludwig in 1836, as a gangrenous infection of the soft tissue floor of the mouth and neck. The potential to spread rapidly to contiguous tissues surrounding the upper airways, notably the glottis, resulted in Ludwig's angina carrying a high mortality rate near 50% in the pre- antibiotic era. It necessitates rapid detection and management to assure respiratory compromise does not occur. This case study is novel as it illustrates handheld bedside POCUS utilization in diagnosing Ludwig’s Angina.

New Onset Lichen Planus And Back Pain Leading To Discovery Of A Peri Aortic Abscess, Monica Diep, Wayne Tamaska, Philip Carhart, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Back pain is a common chief complaint in the emergency department. With the differential ranging from musculoskeletal pain to cauda equina, there are a plethora of diagnoses. Differentiating between benign back pain and back pain that warrants further evaluation and even possible emergent surgical intervention is often a challenge in the acute setting. In this case report, a strange combination of all new symptoms including lichen planus, fevers, chills and atraumatic back pain lead to the eerie and very unexpected diagnosis of a peri-aortic abscess.

The Use Of Osteopathic Manipulative Medicine To Treat Common Pediatric Conditions: A Literature Review, Sonya Priven, Emily Meale, Danielle Cooley

Rowan-Virtua Research Day

Context: Doctors of Osteopathic Medicine (DOs) are physicians who are trained in the practice of osteopathic manipulative treatment (OMT). OMT is a form of manual manipulation that can be applied to the patient’s body to aid the body in its own healing properties. The overprescribing and overuse of medication is currently a problem, as it can result in adverse consequences such as antibiotic resistance. Exploring OMT as either an alternative or as a complementary therapy in the pediatric population is beneficial in potentially curbing antibiotic use and improving symptoms and disease-related processes.

Objective: To explore OMT as a therapy for …

An Unusual Ed Case: Spontaneous Necrotizing Fasciitis Presenting As Hypoxic Pneumonia, Chetna Thawani, Kishan Patel

Rowan-Virtua Research Day

We present a case of necrotizing fasciitis initially presenting as septic hypoxic pneumonia, and discuss imaging modalities and diagnostic evaluation. Necrotizing soft tissue infection (NSTI) is a rapidly progressive surgical emergency with a mortality rate of 30%. In approximately 80% of cases, it is introduced through a break in the skin. It can also occur after any invasive procedure or surgery. It is most commonly associated with skin flora including staph and strep, though polymicrobial infections are most common. It usually presents with signs of systemic infection, including fever, chills, sepsis, altered mental status - and signs of cutaneous involvement …

Case Report: Cavitary Pneumonia In A 28 Year Old Male, Dan Zaayenga, Katelyn Courtney

Rowan-Virtua Research Day

Cavitary pneumonia can be caused by several different mechanisms. Such causes include suppurative necrosis (pyogenic lung abscess), caseous necrosis (tuberculosis), ischemic necrosis (pulmonary infarction) cystic dilatation of lung structures (ball value obstruction and Pneumocystis pneumonia) as well as malignant processes. Causes are subject to both environmental factors and host susceptibility. The most common cause of infectious process is tuberculosis with its propensity to cause extensive caseous necrosis. The potential for secondary infection after an individual develops a cavitary pneumonia is also great as it provides a shelter for various pathogens the flourish in an environment otherwise usually well-guarded by host …

Sigmoid Perforation Extending Into The Abdominal Wall, Zamran Masih, Wayne Tamaska, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Sigmoid colon perforation and spread into the abdominal wall is a rare condition that can occur due to various causes such as diverticulitis, trauma, malignancy, or iatrogenic injury during surgery. Although rare, sigmoid colon perforation into the abdominal wall can result in significant morbidity and mortality if not promptly diagnosed and treated. Most common cause of diverticular disease leading to perforation is diverticulitis, accounting for 60% of all colonic perforations.

Purple Urine Bag Syndrome (Pubs) In A Patient With A Chronic Indwelling Foley, Kelsey Murray, Kishan Patel

Rowan-Virtua Research Day

Purple urine bag syndrome (PUBS) is a rare medical condition characterized by the appearance of purple discoloration in the urine collection bag of patients who use catheters for urinary drainage. PUBS is primarily seen in elderly, female, and institutionalized patients who have chronic indwelling catheters. The discoloration occurs due to the presence of certain bacteria that produce pigments, which react with the plastic materials of the catheter and urine collection bag, leading to the formation of a purple color. In addition to the aesthetic concerns, PUBS may also indicate an underlying urinary tract infection or other medical conditions that require …

Role Of Pseudomonas Aeruginosa Exoenzymes S, T, And Y In The Modulation Of Intrinsic Apoptosis In Pulmonary Microvascular Endothelial Cells, Andrea M. Vavrinek

Undergraduate Honors Theses

P. aeruginosa is the most common cause of ventilator-associated pneumonia in ICU patients. P. aeruginosa uses a type III secretion system to inject exoenzymes S, T, U, and Y into host cells, exhibiting unique effects. Pulmonary microvascular endothelial cells (PMVECs) are used to evaluate cellular changes caused by exoenzymes. ExoY infection of PMVECs leads to cell rounding but does not lead to cell death, unlike ExoS/T. The current study evaluated the exoenzyme-induced modulation of intrinsic apoptosis in endothelial cells. Strain PAK, producing ExoS, T, and Y, was compared to isogenic strains expressing either S, SY, T, TY, Y, or none …
