While the burden of COVID-19 in Rhode Island has diminished since 2020, Rhode Islanders' health continues to be severely impacted. We compared COVID-19 hospitalization rates among Rhode Islanders who did and did not receive the latest COVID-19 vaccination for the 2022-2023 and 2023-2024 COVID-19 seasons (November through March). Crude and age-adjusted rate ratios were calculated for each season comparing hospitalization rates of unvaccinated and vaccinated individuals. During the 2022-2023 season, individuals who were not vaccinated with the bivalent COVID-19 vaccine were 3.6 times (95% CI=2.8-4.6) more likely to be hospitalized for COVID-19 than individuals who received the vaccine, whereas during the 2023-2024 season, not receiving the updated vaccine was associated with a 2.4 times (95% CI=1.8-3.3) higher risk of hospitalization. The study provides the first assessment of the protection from hospitalization provided by COVID-19 vaccinations among Rhode Islanders and highlights the importance of continued vaccination for COVID-19.

Acute Myeloid Leukemia (AML) is a life-threatening illness that requires prompt diagnosis and often immediate treatment. It can present in a variety of manners but most commonly is associated with fevers, fatigue, shortness of breath, or infection. Extramedullary leukemia is a less common finding upon initial presentation, but includes dermatologic manifestations, including leukemia cutis, and rarely, large mass-like presentations known as myeloid sarcomas. While leukemic infiltration of organ systems is a well-described phenomenon, cardiac tamponade is a rare form of presentation. Herein we describe a 58-year-old man with a recent hospitalization for idiopathic cardiac tamponade who re-presented to the hospital with worsening dyspnea and fevers. He was found to have a recurrent pericardial effusion with features concerning for tamponade, as well as worsening thrombocytopenia and macrocytic anemia. Bone marrow biopsy revealed 24% myeloblasts, confirming the diagnosis of AML. Notably, his cardiac symptoms improved with treatment of his leukemia. To our knowledge, this is one of only a few cases of AML with cardiac tamponade as the initial presentation.

Syringocystadenoma papilliferum (SCAP) is a benign adnexal tumor commonly found on the scalp and face, and often associated with nevus sebaceous, with about half of cases appearing in early childhood. SCAP exhibits cystic invaginations with papillary structures and a double-layered glandular epithelium linked to the epidermal surface and stromal plasma cells. We are reporting a rare instance of intradermal SCAP in a 55-year-old male. He sought evaluation for a long-standing asymptomatic dark-pink papule in his left popliteal fossa, measuring 0.7 x 0.5 x 0.4 cm. A shave biopsy revealed papillary dermal fibrosis, glandular epithelium with apocrine secretion, and papillary projections without an epidermal connection. Infundibulofollicular keratinization was observed, along with stromal plasma cells. The patient chose local excision as the treatment option. This case highlights the rarity of intradermal SCAP, especially in the left popliteal fossa, with only one other reported case in the literature.

Raoultella ornithinolytica is a rare, gram-negative environmental enterobacterium. Although infections in humans caused by R. ornithinolytica are uncommon, there are increasing reports implicating it in urinary tract infections, hepatobiliary infections, and bacteremia, designating it as an emerging pathogen. Its habitat is primarily in aquatic environments and soil, with seafood frequently identified as a potential source of infection. While these infections have predominantly been described in immunocompromised patients previously, our case suggests that advanced age may be a significant risk factor. We describe a case of a 73-year-old man presenting with encephalopathy who then was found to have R. ornithinolytica bacteremia from a genitourinary source. Following antibiotic treatment, the infection resolved and the neurologic symptoms improved. To the best of our knowledge, this is the first documented case in the medical literature of R. ornithinolytica featuring a primary neurologic presentation.
