Triple Threat: A Case of Erysipelothrix rhusiopathiae Septicemia Complicated by Multi-Valvular Endocarditis, Spinal Osteomyelitis, and Septic Embolic Stroke.

Erysipelothrix rhusiopathiae is a Gram-positive rod associated with zoonotic infections, most commonly the soft tissues. It can be present in several ways, though most commonly as erysipeloid. Rarely, it may manifest systemically with septic organ involvement such as endocarditis or osteomyelitis. Here, we present the case of a 71-year-old male who presented to the hospital with back pain and neurological deficits. He was found to be bacteremic with E. rhusiopathiae, and imaging demonstrated the presence of multi-valvular endocarditis, spinal osteomyelitis with epidural abscess, and septic embolic stroke. Though such complications of E. rhusiopathiae septicemia have been documented in the literature, this is the first reported case of all three manifestations in one patient.

Worldwide vaccine inequality threatens to unleash the next COVID-19 variant.

The emergence of the Omicron variant (B.1.1.529 BA.1) near Johannesburg heralded the development of an unprecedented number of new COVID-19 infections across South Africa in November 2021. Omicron and its subvariants would soon become the dominant strains across Africa, Europe, and the United States. As with the Delta variant (B.1.617.2), Omicron emerged from an industrialized nation with one of the lowest vaccination rates of any well-developed country. The emergence of variants from undervaccinated regions is a direct consequence of the virus replicating unchecked through an unprotected population. Despite this, the United States and other higher-income nations have adopted a strategy of preferentially inoculating their citizens with multiple and booster doses, whereas lower-income nations struggle with vaccine availability, infrastructure, and their own vaccine manufacturing capability. Much more needs to be done to address worldwide vaccine inequities and prevent the emergence of the next devastating variant. The persistence of the pandemic anywhere remains an ongoing threat to citizens everywhere.

Conquering COVID: How Global Vaccine Inequality Risks Prolonging the Pandemic.

The development of effective vaccines during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has been deemed a towering achievement in modern science. Since the end of 2020, the vaccine rollout has offered the promise of vanquishing the pandemic in the United States and other developed countries. Even as the United States and other wealthier nations encounter both setbacks and successes in their coronavirus disease 2019 (COVID-19) eradication efforts, developing countries around the world are likely to face far less fortunate fates. With much of the world's vaccine production and distribution capacity reserved by wealthier nations, impoverished countries stand to face devastating financial, social, and health-related impacts. The consequences of this disparity will resonate deeply into the collective fabric of these countries, ensuring that the economic and geopolitical imbalance between developed and developing nations will widen even more substantially. Wealthier countries must do more to eliminate the inequality that exists in widespread SARS-CoV-2 vaccine availability in less-developed nations. Like HIV, tuberculosis, malaria, and other global epidemics, COVID-19 cannot be forgotten just because the pandemic is eventually contained from the shores of wealthier nations. For as long as the pandemic rages in any corner of the globe, the world will never be truly rid of COVID-19. And all nations, rich or poor, will suffer the consequences.

On Measles, Vaccination, Social Media Activism, and How to Win Back Our Role as Our Patients' Best Advocates.

Once declared transmission free in the United States less than 20 years ago, measles and other vaccine-preventable diseases have made a spectacular comeback. Waning public support for childhood immunization and subsequent recent outbreaks of vaccine-preventable diseases have been spawned by several technological and social factors, including the erosion of the provider-patient relationship, the emergence of internet-based patient resources and social media sites, and the rise of online healthcare activism. New tools are needed for physicians and healthcare providers to reverse this trend and regain our role as our patients' best advocates.

Sticks and bones: Traumatic phaeohyphomycosis presenting as an epidural scalp abscess and cranial osteomyelitis.

The pigmented molds can cause soft tissue and invasive disease (phaeohyphomycosis) in immunocompetent patients. We describe a 76-year-old male patient who developed a Cladophialophora bantiatum posterior scalp abscess and cranial osteomyelitis following an incidental scalp exposure with a tree branch. Management requires extensive surgical debridement followed by prolonged antifungal therapy.

Infectious diseases resources for the iPhone.

Modern technology has revolutionized the clinician's ability to have vast information resources available literally at one's fingertips. The advent of the smartphone--an integration of the mobile phone with an ultraportable computer, web browser, multimedia player, and camera, has given clinicians the capability to merge their information and communication resources into one compact handheld instrument. Apple's iPhone, and its sister device, the iPod touch, with a combined customer base of more than 50 million users and more than 100,000 downloadable applications, are now the leading handheld platforms for medical personnel to access personal information, medical reference, clinical data, and medically oriented "apps" on the go. The purpose of this article is to provide an overview of some of the diverse infectious diseases-oriented resources available to the iPhone/iPod touch user.

Bite-related and septic syndromes caused by cats and dogs.

Bite infections can contain a mix of anaerobes and aerobes from the patient's skin and the animal's oral cavity, including species of Pasteurella, Streptococcus, Fusobacterium, and Capnocytophaga. Domestic cat and dog bite wounds can produce substantial morbidity and often require specialised care techniques and specific antibiotic therapy. Bite wounds can be complicated by sepsis. Disseminated infections, particularly those caused by Capnocytophaga canimorsus and Pasteurella multocida, can lead to septic shock, meningitis, endocarditis, and other severe sequelae. An emerging syndrome in veterinary and human medicine is meticillin-resistant Staphylococcus aureus (MRSA) infections shared between pets and human handlers, particularly community-acquired MRSA disease involving the USA300 clone. Skin, soft-tissue, and surgical infections are the most common. MRSA-associated infections in pets are typically acquired from their owners and can potentially cycle between pets and their human acquaintances.

An HIV-infected patient with fever, pancytopenia, and renal failure: is this end-stage AIDS?

Histoplasmosis is a fungal infection caused by Histoplasma capsulatum. Although immunocompetent persons with H. capsulatum infections are usually asymptomatic, several clinical syndromes can manifest in immunocompromised patients. We report a case of a 61-year-old man with advanced HIV infection who presented with weight loss, anorexia, and renal failure. His symptoms were initially attributed to end-stage AIDS, but a more specific diagnosis was pursued. Bone marrow biopsy resulted in the discovery of disseminated histoplasmosis. This case illustrates the importance of actively pursuing the diagnosis of an opportunistic infection in persons with end-stage AIDS, treating the opportunistic infection aggressively, and maximizing the effectiveness of antiretroviral therapy.
