- We report an interesting case of a post-traumatic actinomycotic oro-antral fistula of the left posterior maxilla, that was not salvageable via local flaps due to the size of the defect and was managed with the patient-specific titanium implant, fabricated by three-dimensional stereolithographic model planning followed by primary closure.

- Unusual gingival actinomycosis post allogeneic hematopoietic stem-cell transplant: case report. [Case Reports]
- CONCLUSIONS: Opportunistic infections with an unusual clinical appearance are confounding factors in therapeutic decision-making. We present for the first time a case of actinomycosis in the gingival papilla region following allo-HSCT. We also highlight how microbiota profiling through next-generation sequencing could be used to anticipate bacterial infection diagnosis.

- A Rare Case of Pancreatic Actinomyces. [Case Reports]ACG Case Rep J. 2023 Jan; 10(1):e00956.AC
- Actinomyces israelii is a filamentous, gram-positive anaerobic bacterium commonly found in the upper gastrointestinal tract, colon, and female genital tract. Rarely, actinomycosis can infect the pancreas most commonly after pancreatic instrumentation, often mimicking malignancy. We describe a case of a 26-year-old woman who presented with epigastric abdominal pain and nausea without prior pancrea…

- Actinomycosis is a rare opportunistic bacterial infection. It most commonly affects the cervicofacial area and is less common in the gastrointestinal area. Because of the ambiguous clinical pictures, there is a low preoperative diagnosis rate and a high rate of misdiagnoses.

- Urinary Gram staining is helpful in patients with complicated urinary retention, such as prolonged urinary retention and coexisting ureteral retention disease. If gram-positive rods are observed on urine Gram staining in a patient with urinary tract infection, an anaerobic culture of the urine may be helpful for early diagnosis and treatment of Actinomyces infection.

- CONCLUSIONS: Humoral immunogenicity of SARS-CoV-2 vaccines was not reduced in coeliac disease patients compared to controls, although it was in Whipple's disease and CVID patients. Post-vaccination humoral response should be monitored in patients with Whipple's disease and chronic enteropathies on immunosuppressive therapy in order to schedule vaccine booster doses.

- Pediatric pulmonary actinomycosis: A misdiagnosed case report. [Case Reports]
- CONCLUSIONS: Pulmonary actinomycosis is an uncommon bacterial illness that has a variety of clinical manifestations, particularly in young patients. A chest lump with nearby "lace-like" rib bone destruction was the distinguishing characteristic of our case. For appropriate treatment and diagnosis, infection with actinomycosis should be considered when observing a similar chest lump. Pathological biopsy, as a valuable diagnostic tool, can help to distinguish between infectious diseases and thoracic tumors. The pathological manifestations of actinomycosis are characterized by inflammatory lesions that range from purulent to granuloma-like inflammatory processes, and second-generation sequencing of alveolar lavage fluid can help to confirm pathogens.

- Clinical features and treatment outcomes of pulmonary actinomycosis. [Journal Article]Eur Rev Med Pharmacol Sci. 2022 11; 26(21):8064-8072.ER
- CONCLUSIONS: Pulmonary actinomycosis mimics other diseases, often lung cancer. Clinicians should consider the diagnosis of actinomycosis when they detect a mass or consolidation, especially with a low-attenuation center. PET/CT appears not to be useful for differential diagnosis. A shorter course of antibiotic therapy than traditionally recommended appears to be sufficient.
