Severe Upper Airway Obstruction in a Patient With Infectious Mononucleosis.

Infectious mononucleosis (IM) is a clinical disease caused by the Epstein-Barr virus (EBV). Common presenting symptoms include sore throat, lymph node enlargement, fever, and malaise. Although severe upper airway obstruction is uncommon, it is a potentially fatal complication that requires immediate intervention. We describe the case of an 18-year-old Hispanic man who presented with a progressive sore throat and difficulty speaking, requiring endotracheal intubation for airway protection. CT images showed diffuse swelling of Waldeyer's tonsillar ring, multiple enlarged lymphadenopathies, and splenomegaly. Acute EBV infection was confirmed considering clinical presentation and using the heterophile antibody, anti-nuclear and anti-viral capsid antigens, and quantitative PCR. The patient was managed with ventilatory support, empirical antibiotic therapy, and systemic corticosteroids, achieving a positive outcome. Our case illustrates the use of corticosteroids in managing severe upper airway obstruction complicating IM.

A Rare Case of Streptococcus agalactiae Ventriculitis and Endocarditis.

Streptococcus agalactiae infection is typically seen in specific populations, including neonates, pregnant women, and the elderly. These patients have immature, lower, and waning immune systems, which makes them more susceptible to infections. Typical S. agalactiae infections manifest as cellulitis, bacteremia, endocarditis, meningitis, ventriculitis (a rare complication of meningitis), and osteomyelitis. In rare cases, a patient can present with two or more of these typical infection manifestations. The authors present a case of a 48-year-old female with a past medical history of hypothyroidism and chronic back pain who presented to the emergency department with altered mental status. The patient developed nausea and vomiting two days prior to presentation after a family gathering, followed by occipital headache and agitation. On arrival at the emergency department, the patient did not follow commands and was drowsy. The initial examination showed positive for Brudzinski and Kernig signs. The patient was tachycardic, tachypneic, and hypertensive. Initial computed tomography (CT) head without contrast was negative for any acute pathology. Neurology was consulted, and a bedside lumbar puncture was performed, which was significant for elevated opening pressure of 32 cm H2O. The patient was initially started on ceftriaxone, ampicillin, vancomycin, acyclovir, and dexamethasone. Magnetic resonance imaging (MRI) of the brain with and without contrast showed acute ventriculitis, mild leptomeningeal enhancement, and a right posterior corona radiata acute lacunar infarct. Meningitis panel, BioFire (BioFire Diagnostics, Salt Lake City, UT), was positive for S. agalactiae, and the patient was de-escalated to ceftriaxone. Cerebrospinal fluid and blood cultures returned positive for S. agalactiae. A transthoracic echocardiogram was negative for endocarditis, but a transesophageal echocardiogram was significant for a 0.7 × 0.4 cm mobile echodensity attached to the posterior leaflet of the mitral valve (P1/P2 scallop). Repeat blood cultures, additional cerebrospinal fluid analysis, and infectious workup remained negative. Cardiology was consulted and recommended medical treatment. The patient improved clinically, continued ceftriaxone, and was discharged to complete a total of six weeks of treatment with outpatient follow-up evaluations. This case depicts a rare presentation of endocarditis, meningitis, and ventriculitis S. agalactiae infection and the need for a definite treatment algorithm in the management of complicated conditions such as the one presented.

A Case Report of Cytarabine-Induced Red Ear Syndrome.

Cytarabine is an antimetabolite used in the treatment of acute myeloid leukemia which acts by inhibiting DNA synthesis and subsequently cell division. It works on rapidly dividing cells, for that reason, it affects cancer cells, bone marrow and skin cells. Cytarabine has variable cutaneous side effects, the most common one is palmar-plantar erythema which usually presents with a tingling sensation around 5-7 days after cytarabine initiation, followed by erythema and tenderness. Auricular erythema is a rare subtype involving bilateral ears which often presents as ear redness and tenderness as described in the presented case. It is unclear if the skin side effects are related to cytarabine dose or plasma concentration. Most cases of auricular erythema have a benign course and resolve spontaneously. Treatment is mainly conservative. Steroids and antihistamines can be used to speed up recovery given that the pathophysiology is thought to be immediate or due to a delayed hypersensitivity reaction to cytarabine.

Escherichia coli: A Rare Cause of Prosthetic Valve Endocarditis.

Prosthetic valve endocarditis (PVE) is a complication of valve replacement associated with high morbidity and mortality. Escherichia coli (E. coli) is rarely associated with infective endocarditis (IE), accounting for less than 1% of the cases reported. The low frequency is attributed to the organism's low affinity to adhere to the endocardial endothelium. Risk factors that may play a role in developing IE by E. coli include age above 70, diabetes mellitus, a genitourinary source of infection, female sex, healthcare contact, implanted endovascular devices, and immunosuppression. We present a 70-year-old Hispanic woman who arrived with constitutional symptoms and persistent urinary complaints. She had diabetes mellitus, recurrent urinary tract infections, and native mitral valve IE treated with antibiotic therapy and tissue valve replacement. The valve was replaced with a mechanical valve a second time due to malfunctioning. The patient was found to have E. coli bacteremia and ultimately diagnosed with PVE. She was treated solely with ceftriaxone and gentamicin combination therapy resulting in complete resolution of valve vegetations. Our case represents the 11th report of this uncommon disease and illustrates its epidemiology and associated risk factors. We summarize the previous 10 cases reported and highlight the lack of prospective trial data to define optimal therapy for managing PVE caused by E. coli.

An Unusual Case of Candida albicans Empyema in Patient With Gastric Cancer and Colon Metastasis.

Candida empyema is a rare presentation seen in immunocompromised patients, with a high mortality rate if not treated appropriately. We present a rare case of Candida albicans empyema in a patient with gastric cancer undergoing chemotherapy who recently underwent cholecystectomy, successfully treated with fluconazole and drainage. This case not only highlights an unusual presentation of a common pathogen but stresses the fact that when patients with malignancy, present with pleural effusion, candida should be in the differential. Early detection is key in such cases, as outcomes are poor if diagnosis and treatment are delayed.

Burkholderia multivorans: A rare yet emerging cause of bacterial meningitis.

Burkholderia multivorans is a member of the Burkholderia cepacia complex. Although it is usually associated with infections in patients with cystic fibrosis, chronic granulomatous disease, and immunosuppression, central nervous infections are not commonly reported. Moreover, management of these infections is difficult due to multiple mechanisms of bacterial resistance to antimicrobial agents. We report a 55-year-old-man who developed Burkholderia multivorans meningitis after two episodes of central line-associated bloodstream infections. The patient was successfully treated with intravenous trimethoprim/sulfamethoxazole. Burkholderia multivorans is an emerging cause of meningitis with limited antibacterial treatment options. However, trimethoprim/sulfamethoxazole remains an effective agent with excellent penetration into the central nervous system. To our knowledge, this is the first case reported of Burkholderia cepacia complex meningitis identified to the species level as Burkholderia multivorans.

A Case of Recurrent Skin Abscesses: A Conundrum Solved after Obtaining a Thorough Sexual History.

Background. Despite the improvement in patient-physician communication techniques, sexuality and sexual health continue to be challenging areas for discussion during a clinical encounter. Most people are not prepared to discuss sexual matters openly as it can be perceived as negative or inappropriate. Consequently, an incomplete health assessment can result in delayed diagnosis or misdiagnosis. Case Report. We present a 33-year-old woman who developed recurrent left breast abscesses. She required multiple incision and drainage procedures in the operating room followed by antimicrobial therapy. Although she always had an initial improvement with this approach, she continued to have recurrences and development of new abscesses in other body areas. The polymicrobial nature of her recurrences prompted an extensive and costly workup to determine the nature of her condition. The cause was finally elucidated when a thorough sexual history was obtained. Poor hygiene practices during her sexual encounters were considered the cause of her recurrent abscesses. After medical therapy and modification of her sexual practices, she has not developed new recurrences for more than two years. Conclusion. Discussions on sexuality and sexual health are important parts of any clinical encounter, yet frequently forgotten or avoided. Becoming aware of their importance would avoid delayed diagnosis or misdiagnosis.

Toluene inducing acute respiratory failure in a spray paint sniffer.

BACKGROUND: Toluene, formerly known as toluol, is an aromatic hydrocarbon that is widely used as an industrial feedstock and as a solvent. Like other solvents, toluene is sometimes also used as an inhalant drug for its intoxicating properties. It has potential to cause multiple effects in the body including death. CASE REPORT: I report a case of a 27-year-old male, chronic spray paint sniffer, who presented with severe generalized muscle weakness and developed acute respiratory failure requiring ventilatory support. Toluene toxicity was confirmed with measurement of hippuric acid of 8.0 g/L (normal <5.0 g/L). CONCLUSIONS: Acute respiratory failure is a rare complication of chronic toluene exposure that may be lethal if it is not recognized immediately. To our knowledge, this is the second case of acute respiratory failure due to toluene exposure.
