First-in-Human Randomized Controlled Pilot Trial of a Maxillofacial Drug Delivery Platform for Low-Dose Systemic Delivery. (PubMed, Cureus) - "Methods In this parallel-group, pilot RCT (n = 20), patients undergoing maxillary first molar endodontic therapy received either 400 mg of oral metronidazole (control group; n = 10) or 5 mg of metronidazole administered using the maxillofacial platform (study group; n = 10)...No local or systemic AEs were observed in either group. Conclusion The maxillofacial drug delivery platform demonstrates potential for safe and rapid systemic drug delivery at low doses."

Hematogenous Fusobacterium Infection Presenting as Multifocal Brain Abscesses Without Contiguous Source (AAN 2026) - "Head CT revealed multiple right-hemispheric lesions with vasogenic edema and 4 mm midline shift; MRI demonstrated multiple ring-enhancing supratentorial abscesses, largest in the right parietal and parieto-occipital regions.He received empiric vancomycin, cefepime, and metronidazole, followed by right parietal craniotomy with evacuation of purulent material; cultures remained sterile...Diagnostic studies were negative for co-infection, including HIV, and showed no evidence of immunocompromise.He was discharged at his neurologic baseline with symptom resolution, on a three-week course of IV ceftriaxone and oral metronidazole, with outpatient follow-up. This case describes a rare hematogenous Fusobacterium infection in an immunocompetent patient, presenting with multifocal brain abscesses and no contiguous source. The absence of typical predisposing factors, including head or neck infection, trauma, or instrumentation, makes this presentation particularly uncommon."

Pharmacokinetic analysis and steady-state predictions of different preparations of metronidazole administered per rectum in adult horses. (PubMed, J Vet Intern Med) - "With the tested preparations, rectal administration of metronidazole at a standard dosage of 20 mg/kg yielded subtherapeutic plasma concentrations. Administering a 4-fold higher dose rectally in water might overcome these limitations. Oral and intravenous routes remain the preferred methods for administering metronidazole in horses."

Fulminant Clostridioides difficile Infection During Repeated High-Dose Cytarabine Consolidation for Acute Myeloid Leukemia: A Fatal Case. (PubMed, Cureus) - "The initial episode was mild diarrhea during myelosuppression and was managed by oral metronidazole. This case illustrates the unpredictable severity of recurrent CDI during intensive chemotherapy. It highlights the critical importance of guideline-adherent antimicrobial therapy, particularly the use of fidaxomicin or vancomycin rather than metronidazole in high-risk patients."

CONCURRENT CLOSTRIDIUM DIFFICILE COLITIS AND CYTOMEGALOVIRUS INFECTION AS A CAUSE OF PERSISTENT DIARRHEA AFTER AUTOLOGOUS HEMATOPOIETIC STEM CELL TRANSPLANTATION FOR NON-HODGKIN LYMPHOMA FOLLOWING BENDAMUSTINE-BASED CONDITIONING. (PubMed, Acta Clin Croat) - "After treatment with oral metronidazole, vancomycin and fidaxomicin, diarrhea persisted despite undetectable C. difficile toxin, with elevation of hepatic enzymes. Eventually, CMV infection was diagnosed by real-time polymerase chain reaction and treated with ganciclovir and valganciclovir...Bendamustine-induced colitis and prior rituximab treatment may have been additional risk factors in this patient. Therefore, more comprehensive workup of diarrhea is needed in ASCT recipients treated with these agents."

METABOLIC ACTIVITY OF CERVICAL IMMUNE CELLS DECREASES AFTER SUCCESSFUL TREATMENT OF BACTERIAL VAGINOSIS (WRMC 2026) - "Cervical biopsy samples were collected from women before vs after successful treatment of BV with a standard course of oral metronidazole... This increase in puromycin incorporation indicates increased translation and activation of CD4+ and CD8+ in the presence of BV. Despite limited sample size, consistent increases in CD4+ and CD8+ cell metabolism during BV infection indicates that BV metabolically influences cervical immune cells and this effect can be reversed by successful BV treatment. This finding suggests a unique mechanism by which BV may increase HIV susceptibility and may inform novel therapeutics for BV."

Anaerobic pericarditis due to Clostridium ramosum: First known case report. (PubMed, IDCases) - "He was treated with intravenous ampicillin-sulbactam followed by oral metronidazole, with resolution of the effusion and no recurrence on follow-up. Importantly, routine anaerobic cultures of pericardial fluid should be considered to avoid missed diagnoses. Recognition of rare anaerobic pathogens in pericardial infections expands the understanding of their pathogenic potential and informs future diagnostic and therapeutic approaches."

From the Ear to the Brain: Otitis Externa Complicated by Coalescent Mastoiditis Leading to Temporal Lobe Abscess and Wernicke's Aphasia. (PubMed, Cureus) - "Given the small size of the abscess and absence of mass effect, she was managed nonoperatively with intravenous cefepime and vancomycin and oral metronidazole, alongside intensive glycemic optimization. She completed a six-week antimicrobial regimen and achieved full neurological recovery with near-complete radiographic resolution. This case highlights that inadequately treated otitis externa may serve as a suspected otogenic source of intracranial abscess in patients with uncontrolled diabetes and emphasizes the importance of early MRI evaluation when neurologic symptoms arise, even when CT imaging and laboratory findings are initially reassuring."

Revisiting the Disulfiram-Like Reaction Between Alcohol and Oral Metronidazole. (PubMed, Sex Transm Dis) - "While all four case reports and one older clinical trial reported a potential link between some oral 5-nitroimidazoles and DLR, 3 clinical trials, one cross-sectional chart review, and 2 experimental animal studies did not. Thus, the available evidence does not strongly support a clinically significant interaction between alcohol and oral MTZ, calling into question the need for strict alcohol abstinence during treatment."

Male Partner Treatment and the Potential Sexual Transmission of Bacterial Vaginosis: Considerations for Patient Counseling and Clinical Application in the United States. (PubMed, Am J Obstet Gynecol) - "However, for the first time, an open-label, randomized controlled trial in Australia showed a decrease in BV recurrences in women whose male partners were treated with a combination of oral metronidazole and topical clindamycin cream over 12 weeks. This has resulted in increasing questions from patients regarding both MPT and the sexual transmissibility of BV. Here, we review evidence regarding the sexual transmission of BV, discuss complexities with potential implementation of MPT, and provide a framework from which to counsel patients."
