  • A Rare Case of Pancreatic Actinomyces. [Case Reports]
    ACG Case Rep J. 2023 Jan; 10(1):e00956.Poche M, Liu K, … Sealock R
  • 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…
  • Urinary Actinomyces infection with a urachal remnant. [Case Reports]
    BMJ Case Rep. 2022 Dec 08; 15(12)Kashiwagi R, Watari T, … Kikuchi K
  • 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.
  • Pediatric pulmonary actinomycosis: A misdiagnosed case report. [Case Reports]
    Front Pediatr. 2022; 10:955554.Yilin Z, Xinyi L, … Hongwu Z
  • 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.
  • Choanal Polyps Originating from Unusual Sites: A Rural Tertiary Care Center Experience. [Journal Article]
    Int Arch Otorhinolaryngol. 2022 Oct; 26(4):e683-e687.Joseph L, Prasad KC, … Harshitha N
  • Introduction Choanal polyps are benign lesions arising from the sinonasal mucosa, extending through the choana into the nasopharynx. Though polyps arising from the maxillary sinus and extending to the choana are common, polyps arising from the sphenoid sinus ostium, posterior part of middle turbinate, and inferior and middle meatus are quite uncommon. Objective To document the site of origin of c…
  • Imaging of Uncommon Bacterial, Rickettsia, Spirochete, and Fungal Infections. [Review]
    Neuroimaging Clin N Am. 2023 Feb; 33(1):83-103.Saini J, Sankhe SS, Lee A
  • This article reviews uncommon bacterial (brucellosis, actinomycosis, neuromelioidosis, nocardiosis, whipple disease, and listeriosis), Rickettsia, spirochete (neurosyphilis and Lyme disease), and fungal (mucormycosis, aspergillosis, candidiasis, cryptococcosis, and Cladophialophora bantiana) diseases affecting central nervous system (CNS), focusing primarily on their cranial manifestations. These…
  • Clinical features and treatment outcomes of pulmonary actinomycosis. [Journal Article]
    Eur Rev Med Pharmacol Sci. 2022 11; 26(21):8064-8072.Hoca NT, Berktaş MB, … Tanrıkulu FB
  • 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.
  • [Clinical presentation and short-term treatment of pulmonary actinomycosis]. [Case Reports]
    Rev Med Suisse. 2022 Nov 16; 18(804):2177-2180.Abdulkarim A, Pouxe M, … Kokkinakis I
  • Actinomycosis is an uncommon disease caused by Actinomyces, a commensal of the oropharyngeal, digestive, and genital tract. Commonly, it manifests as cervicofacial infection and is often related to poor oral health, smoking, chronic alcoholism or immune deficiency. Pulmonary actinomycosis is a rare disease, characterized by unspecific clinical, biological, and radiological manifestations that may…
  • Colloid cyst with hyphal-like structures: A rarity that mimics actinomycosis of the third ventricle. [Journal Article]
    Clin Neuropathol. 2022 Nov 11 [Online ahead of print]Aldabek D, Deckert M, … Warnke JP
  • Colloid cysts are histologically well defined and consist of three main components, a capsule, with an underlying epithelial layer, and a mucinous heart. In our case, we present a 35-year-old female with acute deterioration of level of consciousness. An emergent CT scan showed a cystic lesion occluding the intraventricular foramen. The lesion was endoscopically excised through a transfrontal appr…
  • Massive hemoptysis as a complication of pulmonary actinomycosis: a case report. [Case Reports]
    Cir Cir. 2022; 90(5):689-692.Ibarra-Celaya JM, Leyva-Moraga E, … Castillo-Ortega G
  • Massive hemoptysis is a rare life-threatening complication of pulmonary actinomycosis that should be treated promptly due to the risk of asphyxiation and hemodynamic instability. We present the case of a 57-year-old female who was presented to our center with massive hemoptysis. Thoracic computed tomography scan revealed a cavitated lesion with perilesional ground-glass opacity. Right lower lobec…
  • Appendicular Actinomycosis: Behind the Curtains of Appendicitis. [Case Reports]
    Cureus. 2022 Sep; 14(9):e29709.Completo S, Veríssimo M, … Sande Lemos P
  • Actinomycosis is a rare, indolent, and multisystemic infection caused by Actinomyces, commensal bacteria of the oral and intestinal flora. It usually occurs due to tissue disruption. It affects the abdominal region in 20% of cases, and the most common presentation is a perforated appendix. Symptoms are nonspecific, which makes differential diagnosis a challenge. We present the case of a healthy, …
  • Endobronchial Actinomycosis: A Case Report. [Case Reports]
    Niger J Clin Pract. 2022 Oct; 25(10):1758-1761.Afsin E, Bacaksu E
  • An extremely rare disease with a slow course, actinomycosis has a high mortality risk when not properly treated. Pulmonary actinomycosis is clinically and radiologically analogous with tuberculosis, foreign body aspiration, lung abscess, or lung cancer. Therefore, it often causes misdiagnosis or delay in diagnosis. A 65-year-old male patient, being followed up with the diagnosis of chronic obstru…
  • Isolation and characterization of Buchananella hordeovulneris from feline pyothorax. [Case Reports]
    Braz J Microbiol. 2022 Dec; 53(4):2329-2334.Samoel GVA, Herbichi AP, … Cargnelutti JF
  • A 1-year-old female mixed-breed cat was admitted to a veterinary hospital in Southern Brazil with tachypnea, low thoracic amplitude, restrictive breathing pattern, and cyanotic mucous membranes 2 days after elective castration surgery. Radiography revealed pleural effusion, and approximately 100-200 mL of fluid was collected by thoracocentesis. The reddish purulent exudate contained large numbers…
