Uncommon Culprit, Familiar Foe: A Case of Septic Thrombophlebitis of the Internal Jugular Vein Triggered by Klebsiella Bacteremia.

Septic thrombophlebitis of the internal jugular vein is characterized as Lemierre syndrome. Patients typically present with sore throat and fever and may present with a tender neck mass due to thrombophlebitis of the internal jugular vein. We present the case of a 57-year-old male with neck pain, fever, chills, and headaches who was diagnosed with internal jugular vein septic thrombophlebitis associated with catheter-related introduction of bacteria.

Brain Abscesses by Nocardia: An Interesting Case.

The successful management of disseminated Nocardia infection is not well described in medical literature. Immunocompetent individuals presenting with complicated and widespread Nocardia infection is an uncommon phenomenon. We describe an interesting case of a large Nocardia abscess in the brain in an immunocompetent patient that was aspirated. The patient clinically improved and was discharged home on a prolonged course of intravenous antibiotics and close outpatient follow-up. He successfully finished the antibiotic therapy for one year, and repeat imaging studies suggested the resolution of the abscess. With this case, we also intend to do a brief literature analysis about the management of brain abscess caused by Nocardia species.

The Clinical Value of Methicillin-Resistant Staphylococcus aureus Nasal Screening in the Management of Diabetic Foot Infections.

Nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA) remains an important risk factor for diabetic foot infections (DFIs). We explored herein the clinical value of MRSA-nasal screening in the management of DFIs. In this retrospective case-control study, patients admitted with a DFI between 1/1/2014-6/30/2020 were studied and divided into cases (positive MRSA-nasal screening) and controls (negative MRSA-nasal). We included 171 patients (22 cases and 149 controls). MRSA nasal screening had a negative predictive value (NPV) of 86%. Compared to controls, cases were treated with intravenous vancomycin for a longer duration: (median [IQR], 5[3,11] vs 2[2,6]) days, P = .037). In multivariate analysis, a negative MRSA nasal screening was associated with a 74% decreased risk of AKI (OR = 0.26, 95% CI = 0.07-0.89). MRSA nasal screening in patients admitted with DFI has a high NPV. Obtained early, it can shorten the duration of intravenous vancomycin, consequently preventing AKI.

Gemella endocarditis.

We herein present the case presenting to our facility complaining of a fever of two months duration, who underwent dental procedure. Patient was diagnosed with infective endocarditis secondary to an uncommon bacteria: Gemella haemolysans. Patient was found to have concomitant severe mitral valve regurgitation. Our patient did not have any comorbidity or risk factor beside his dental procedure. Our patient received intravenous antibiotic therapy for six weeks and was scheduled for mitral valve replacement.

Secondary Pneumothorax Induced by a Bronchopleural Fistula in a Patient With COVID-19 Pneumonia.

COVID-19 is a multi-system disease caused by severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2). One of the main highlights of the disease is the development of pneumonia complicated by adult respiratory distress syndrome. While spontaneous pneumothorax has been reported in some patients with COVID-19, bronchopleural fistula has seldom been reported as the primary cause in these cases. We describe the rare case of a young patient who developed a pneumothorax complicating COVID-19 and was found to have a bronchopleural fistula and empyema secondary to Staphylococcus aureus superinfection.

A Rare Case of Streptococcus Pneumoniae Causing Malignant Otitis Externa Complicated by Skull Base Osteomyelitis.

Skull base osteomyelitis is an aggressive infection involving bones of the skull. It is a rare complication of malignant otitis externa, caused by the contiguous spread of the infection. Patients are mostly elderly with comorbidities that compromise immunity. It is atypical for Streptococcus species to be encountered in basilar skull osteomyelitis. Here we present the case of an 80-year-old male with multiple comorbidities including diabetes mellitus with a two-month history of right ear pain associated with occasional discharge and diminished hearing who was found to have bacteremia and basilar skull osteomyelitis with Streptococcus pneumoniae isolated from blood and otorrhea fluid cultures. This unusual presentation of S. pneumoniae related skull base osteomyelitis could be attributed to an undiagnosed pancreatic cancer at the time of presentation. Malignant otitis externa can progress into invasive disease in the head and neck; almost all cases tend to be caused by Pseudomonas aeruginosa but unusual cases, such as this, can be caused by Streptococcus pneumoniae.

A Case of Primary Sternomanubrial Osteomyelitis With Oxacillin-Resistant Staphylococcus aureus (ORSA) Bacteremia.

We herein report the case of a previously healthy 26-year-old male patient who presented to our hospital with chest pain and fevers. Investigations revealed oxacillin-resistant Staphylococcus aureus (ORSA) osteomyelitis of the manubrium, for which no inciting event or background was identified, classifying it as primary sternomanubrial osteomyelitis (PSO). The patient was appropriately treated with intravenous antibiotics, resulting in clinical improvement. The sternomanubrial site without trauma has rarely been described in the literature.

Multivalvular infective endocarditis with Proteus mirabilis.

Proteus species belong to the Enterobacteriaceae family and are gram-negative-rods, commonly known to cause urinary tract infections and asymptomatic bacteriuria in elderly patients with risk factors such as diabetes mellitus and urinary catheterization. However, Proteus species are rarely known to cause infective endocarditis. We present a case of an 85-year-old female who presented due to decreased responsiveness with urine and blood cultures growing Proteus mirabilis. While she was being treated for her urinary tract infection, her echocardiogram showed vegetation on the left coronary cusp of the aortic valve and left pulmonic valve leaflet. Uncontrolled tachyarrhythmias and new-onset atrial fibrillation complicated the hospital course. Later, she became bradycardic during the hospital stay, and all rate-control medications were held. Unfortunately, she went into cardiac arrest and spontaneous circulation could not be established with resuscitation attempts and she expired. To our knowledge, this is a rare case of native valve infective endocarditis secondary to Proteus mirabilis, leading to uncontrolled tachyarrhythmias and death.

Babesiosis and the human immune system.

Immunological phenomena have been described in infections such as infective endocarditis. However, none has been reported in the context of Babesiosis. Babesiosis is a tick-borne illness caused by the protozoa of the genus Babesia and causes infections that range from asymptomatic to severe and sometimes are fatal. This report presents the first case of ANCA/ANA positive severe babesiosis in an asplenic patient treated with repeated red blood cell exchange transfusion.

Catastrophic right-sided Candida empyema from spontaneous esophageal perforation.

Right-sided empyema secondary to esophageal rupture are rare but reported in the medical literature. We describe an atypical CASE of right-sided empyema with Candida Tropicalis, Candida Glabrata, and Staphylococcus lugdenensis leading to a diagnosis of spontaneous esophageal rupture. We concluded that pleural effusion with fungal and multi-organism growth should immediately raise suspicion for underlying missed esophageal perforation. Prompt diagnosis of esophageal perforation can prevent fatal complications like pleuritis, pneumothorax, hydrothorax, pneumomediastinum, mediastinitis, acute respiratory distress syndrome, and septic shock.

First case report of pulmonary embolism with Zoster Sine Herpete.

BACKGROUND: Varicella-Zoster Virus (VZV) infection is known to cause coagulation abnormalities leading to pulmonary embolism and ischemic strokes. The incidence of vascular and thrombotic complications with Zoster Sine Herpete has been reported very infrequently in the medical literature. CASE PRESENTATION: A 32-year-old man with no significant past medical history presented to Emergency Room with right-sided facial weakness and headache. We saw no rash on physical examination. A sub-segmental pulmonary embolus was found on C.T. angiography of the chest. VZV was detected on Lumbar Puncture studies. The patient responded well to anti-viral treatment and was discharged home without any complications. CONCLUSION: The suspicion of thrombo-embolic complications should be high with Zoster Sine Herpete. Screening for coagulopathies and timely initiation of anticoagulation should be carried out in appropriate clinical settings.

Case report: aseptic meningitis secondary to varicella-zoster virus (VZV) without an exanthem post MMR vaccination.

BACKGROUND: Varicella-zoster virus (VZV) is a known cause of aseptic meningitis, with a predisposition for an immunocompromised population. A dermatomal rash usually accompanies aseptic meningitis secondary to VZV. CASE PRESENTATION: We report the case of a 31-year-old male with a history of chickenpox in childhood and recent shingles who presented with severe frontal headaches secondary to VZV meningitis. The patient had also recently received the measles-mumps-rubella (MMR) vaccine. He recovered without any neurological sequala. CONCLUSION: This case report describes an immunocompetent patient with recent MMR vaccination who developed aseptic meningitis secondary to VZV without any dermatomal involvement (Zoster Sine Herpete).

First case report of acute cholangitis secondary to Cronobacter sakazakii.

INTRODUCTION: Cronobacter sakazakii is an opportunistic Gram-negative, rod-shaped bacterium which may be a causative agent of meningitis in premature infants and enterocolitis and bacteremia in neonates and adults. While there have been multiple cases of C. sakazakii infections, there have been no acute cholangitis cases reported in humans. CASE PRESENTATION: An 81-year-old male with a past medical history of basal cell carcinoma, alcoholic liver cirrhosis, transjugular intrahepatic portosystemic shunt procedure, complicated by staphylococcus bacteremia, pituitary tumor, glaucoma, and hypothyroidism presented to the emergency room with the complaint of diffuse and generalized 10/10 abdominal pain of 1 day's duration. There was a concern for pancreatitis, acute cholangitis, and possible cholecystitis, and the patient underwent a percutaneous cholecystostomy tube placement. Blood cultures from admission and biliary fluid cultures both grew C. sakazakii. The patient was treated with a carbapenem and clinically improved. CONCLUSIONS: The case study described a patient with multiple medical comorbidities that presented with C. sakazakii bacteremia and cholangitis. While this bacterium has been implicated in other infections, we believe this is the first time the bacteria is being documented to have caused acute cholangitis.

Case report: Epiglottitis in the setting of COVID-19.

Epiglottitis is an uncommon, potentially fatal infection of the epiglottis that can lead to complete upper airway obstruction. Isolated pathogens are usually nasopharyngeal bacteria, most commonly Haemophilus influenzae type b (Hib). While the incidence of epiglottitis has diminished significantly over the years due to widespread vaccination against Hib, the proportion of epiglottitis caused by other pathogens has increased. In this report, we introduce an unseen presentation of acute epiglottitis associated with severe acute respiratory distress syndrome--coronavirus2 (SARS-CoV-2), who presented to the emergency department with throat pain and odynophagia that quickly resulted in respiratory distress. Clinicians should be aware of airway edema's concomitant presence in patients with acute epiglottitis and COVID-19 and maintain a low threshold for intubation. The rapidly progressive nature of COVID-19 and its complications may preclude intubation later on in the patient's clinical course, potentially necessitating an emergent surgical airway.

A Curious Case of MRSA Bacteremia and Septic Pulmonary Embolism Secondary to Peripheral Venous Catheter.

BACKGROUND: Central venous catheters (CVCs) have been frequently associated with septic thrombophlebitis, bacteremia, and septic emboli. Right-sided infective endocarditis is seen concurrently in patients with septic pulmonary emboli. A case of methicillin-resistant Staphylococcus aureus (MRSA) bacteremia and septic pulmonary emboli secondary to infected peripheral venous catheter (PVC) is reported. Transesophageal echocardiogram (TEE) showed no evidence of infective endocarditis. Case Presentation. A 44-year-old female presented to E.R. with left upper extremity pain and swelling at the previously inserted peripheral 18-gauge intravenous catheter site. She also had chest pain, which worsened with inspiration. The patient was found to be in septic shock. Her clinical condition deteriorated acutely. Right upper extremity deep venous thrombosis (DVT) and pulmonary emboli were seen on imaging. Blood cultures grew MRSA. Transthoracic and transesophageal echocardiograms showed no vegetations. The patient responded well to appropriate antibiotics and anticoagulation. CONCLUSION: Peripherally inserted catheters are an important portal for pathogen entry and need periodic site assessment and frequent evaluation of their need for insertion. Septic pulmonary emboli can also be seen without any evidence of right-sided infective endocarditis.

Co-infection of hepatitis E virus and Plasmodium falciparum malaria: A genuine risk in sub-Saharan Africa.

BACKGROUND: There is a high prevalence of malaria and viral hepatitis in South Africa. Co-infection with Plasmodium malaria (leading to cerebral malaria) and hepatitis E virus (HEV) is a rare phenomenon. CASE PRESENTATION: A 33-year-old African American male with no past medical history developed altered mental status on his return from Ivory Coast. His blood tests were significant for renal and liver failure and a high Plasmodium parasite burden of 33% on the blood smear. Interestingly, he also had a positive result for hepatitis E IgM. The patient was effectively treated with aggressive hydration and intravenous (IV) artesunate. CONCLUSION: Our report is the first to our knowledge in the cerebral malaria literature on a patient with hepatitis E co-infection. This exciting case emphasizes the importance of considering all kinds of endemic infectious diseases when evaluating sick returning travelers presenting to the emergency department.

Carbapenemase producing Klebsiella pneumoniae (KPC) meningitis from chronic otitis media.

Meningitis and brain abscess caused by carbapenemase-producing Klebsiella pneumoniae (KPC) is rarely described in the medical literature. Such infections have been described after neurosurgical medium or post-trauma. We describe an unusual case of KPC meningitis originating from with long term intravenous antibiotics.

Erysipelothrix rhusiopathiae endocarditis.

Erysipelothrix rhusiopathiae is a zoonotic gram positive coccobacillus. It is rarely found in humans as an occupational pathogen that mainly infects animal handlers. There are three forms of human infection: localized erysipeloid, diffuse cutaneous form and lastly, bacteremia that could progress to infective endocarditis. We present a case of a 59-year-old male who was found to have E. rhusiopathiae bacteremia that was diagnosed as aortic valve endocarditis with severe aortic regurgitation. The patient was treated with ampicillin-sulbactam then transitioned to six weeks of intravenous ampicillin. This report summarizes a rare organism that causes a serious human infection and discusses its epidemiology, clinical presentation, diagnosis and treatment options.

Secondary encephalocele in an adult leading to subdural empyema.

Brain abscesses are an uncommon but potentially fatal infection. They can spread directly from an adjacent source or hematogenously from a distant source. Encephaloceles represent a rare form of neural tube defects that can potentially be complicated by the development of meningitis or brain abscess. We report a case of a 63-year-old female who presented with bilateral lower extremity weakness and was ultimately found to have a Streptococcus pneumoniae subdural empyema and an associated frontal lobe encephalocele extending through the left frontal sinus. She was treated with surgical drainage, intravenous antimicrobials, and ultimately surgical repair of the encephalocele. This report highlights a unique presentation of brain abscess. Clinicians should be aware of this potential infectious complication of a neural tube defect.
