Uncommon Streptococcus Constellatus Meningitis Leading to Pulmonary Abscess and Brainstem Infarct in an Immunocompetent Patient.

BACKGROUND Except for neonates, streptococci other than Streptococcus pneumoniae are a rare cause of acute bacterial meningitis. Streptococcus constellatus is a member of the Streptococcus anginosus group of gram-positive streptococci. It is a commensal microbe of the mucosae of the oral cavity, gastrointestinal tract, and urogenital tract. Rarely, it becomes pathogenic and causes contiguous or distant infections after mucosal damage. This report describes a 19-year-old immunocompetent man who developed bacterial meningitis, lung abscess, and brainstem infarct secondary to Streptococcus constellatus. CASE REPORT A 19-year-old immunocompetent man presented to the Emergency Department with a 4-week history of headache and neck pain. He was febrile on arrival. Physical examination revealed ataxia, upper-limb discoordination, and a positive Brudzinski sign. Cerebrospinal fluid and blood cultures were positive for Streptococcus constellatus, identified by matrix-assisted laser desorption ionization - time of flight mass spectrometry. Computed tomography of the chest demonstrated a lung abscess measuring 7×3.5×3 cm. A magnetic resonance imaging scan of the head revealed a 1.8×0.7 cm acute infarct in the right pons. The patient was treated initially with intravenous ceftriaxone and vancomycin before culture and sensitivity results, in addition to intravenous dexamethasone. After culture and sensitivities resulted, antibiotics were transitioned to a 4-week course of intravenous penicillin. The patient survived with no neurological consequences upon discharge. CONCLUSIONS Streptococcus constellatus should be suspected as an etiological agent for bacterial meningitis and other rare complications such as brainstem infarction and lung abscess, even in immunocompetent patients.

Angiotensin-Converting Enzyme (ACE) Inhibitor-Induced Angioedema in an African American Male With Coronavirus Disease 2019 (COVID-19).

Angioedema is a condition characterized by non-pitting swelling of the subcutaneous or submucosal tissues in particular the face, lips, and oral cavity. Angiotensin-converting enzyme (ACE) inhibitors are known to contribute to the development of angioedema by increasing the levels of bradykinin and its active metabolites. Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is hypothesized to contribute to the development of angioedema by modifying ACE II levels and further increasing the level of bradykinin in patients taking ACE inhibitors. African Americans may be at particular risk of developing angioedema with concomitant SARS-CoV-2 infection and ACE inhibitor use. This case involves a 31-year-old African American male diagnosed with coronavirus disease 2019 (COVID-19) who developed angioedema while taking an ACE inhibitor.

Arteriovenous Fistula for dialysis - Let's Google it. Readability and quality of online information.

BACKGROUND: This study evaluated the readability and quality of information regarding arteriovenous (AV) fistula for dialysis on the Internet in the English language. STUDY DESIGN: Using Google© search, the keywords "AV Fistula for dialysis" were searched. The top 75 ranking sites were analyzed. One website was excluded due to repetition. Each landing page was assessed independently by two authors (RB, LR) for readability using the Flesch Reading Ease Score (FRES) and Gunning Fog Index (GFI). Web site quality was assessed using the DISCERN instrument. The individual position of the top 15 websites in the search engine ranking order list was noted. The country of origin, organization type and issuance of Health on the Net (HoN) Certification was recorded. Statistical analyses were performed using unpaired t-tests and ANOVA variance. RESULTS: The mean GFI score was 9.2 and the mean FRES score was 50.6, indicating poor readability. The mean DISCERN score was 48.4, indicating weak quality of websites. Website quality was influenced by the academic/healthcare organization type (p = 0.012). Organization type was not found to impact GFI and FRES scores. Presence of a HoN Certification was not found to impact the quality of information. The majority of sites originated from the United States (61%). CONCLUSION: Our study demonstrates that internet information pertaining to AV fistula for dialysis is of poor quality necessitating improvements to readability and overall website quality to improve the patient experience. Further research into how to improve healthcare web information is needed.
