“…Further studies are required to explore the link between diabetes mellitus, as the phenotype of a pathological condition, and causative pathogens, while it is also important to determine whether such pathogens act independently or as members of the overall flora. Recently, Sakanaka et al have reported that Strepto- coccus gordonii ArcD plays crucial roles in mediating arginine uptake and promoting bacterial growth, particularly under low-arginine conditions (30). It has also been suggested that metabolic cross-feeding occurs in complex biofilms, enabling the bacterial community to function cooperatively and resist the effects of antimicrobial agents to a degree up to 1,000 times greater than is possible for individual planktonic cells (31).…”

Over 700 bacterial species have been detected in the oral cavity. Several studies have suggested that periodontitis is associated with systemic disorders such as diabetes mellitus, indicating a key role for oral microbiota in human health. However, the relationship between oral microbiota and diabetes has not been well clarified. Therefore, we conducted microbiome analysis of saliva samples obtained from 15 elderly residents (3 with type 2 diabetes mellitus [DM] and 12 without diabetes [non-DM]) at three different nursing homes, as well as 9 young healthy controls (HC). Genomic DNA was extracted from each sample, and then the V4 region of the 16S rRNA gene was amplified and sequenced.Alpha diversity, in terms of operational taxonomic unit richness, was significantly higher in samples from the non-DM group than in those from the HC group. Weighted UniFrac distance analysis showed that salivary microbial communities in the DM group were separately clustered. Furthermore, in the DM group, Actinomyces and Selenomonas showed significantly higher abundance, whereas Alloprevotella showed significantly lower abundance, relative to the non-DM group. Although our findings were limited by the small sample size, oral bacterial diversity in the DM group was clearly different from that in the non-DM group.

“…18 Koshiyama et al presented pelvic actinomycosis which was treated with neoadjuvant chemotherapy, carboplatin, doxorubicin and cyclophosphamide, because it was misdiagnosed as an advanced ovarian cancer. 19 Since cultures of Actinomyces species show very low yield, it is difficult to distinguish a solid mass of pelvic actinomycosis from a malignant tumor before surgery. Our patient did not present with fever, leukocytosis or elevated ESR although anemia was present.…”

Pelvic actinomycosis with hydronephrosis and colon stricture simulating an advanced ovarian cancer

et al. 2008

Pelvic actinomycosis is an uncommon disease in humans. It has nonspecific and variable clinical features, and thus it is difficult to diagnose. Moreover, appropriate management is delayed or overlooked because it can sometimes simulate advanced ovarian cancer. We report a case of pelvic actinomycosis which manifested with hydronephrosis and bowel stricture, lymph node enlargement and increased level of tumor marker caused by a large pelvic mass. Since this case showed clinical findings mimicking an advanced ovarian carcinoma, it was surgically diagnosed as actinomycosis after neoadjuvant chemotherapy.

“…Die eigene Beobachtung eines tiefen Rektumtumors, der nach laparoskopischer Kontinuitätsresektion zur histologischen Verifizierung führte, ist Veranlassung, dieses seltene Krankheitsbild zu beschreiben. [2,4,5,7,16,17]. Nach Ausschöpfung der präoperativen Diagnostik besteht die Indikation zur Laparotomie mit einer Probeexzision [14,15] oder einer resezierenden Maßnahme [3,4,6,7,11,17].…”

“…Hier handelte es sich um einen isolierten Befall des unteren Mesorektums und Rektums. Das chirurgische Vorgehen reicht von Hysterektomien mit Salpingo-Oophorektomie [4,11,15,17] bis zu komplexen multiviszeralen Resektionen einschließlich abdominoperinealer Resektionen und Kolostomaanlagen [3,5,6,16,20]. Mit der Laparoskopie ergeben sich neue und wenig invasive diagnostische Möglichkeiten, einschließlich der Probeexzision.…”

Aktinomykose des Rektums: Die Imitation einer malignen Neubildung – Fallbericht zur laparoskopischen Rektumresektion

Actinomycosis of the Rectum: Imitation of a Malignant Neoplasia – Case Report of a Laparoscopic Rectum Resection Background: Actinomycosis of the rectum is rare. The diagnosis of this condition is a challenge. Particularly in cases without fistula, there may be difficulties to differentiate actinomycosis from carcinoma. Case Report: We report the case of a 54-year-old woman with a tumor of the lower rectum. Ultrasonography, computed tomography, and endoscopic ultrasonography suspected rectal malignancy with lymph node metastases. However, this could not be proved by histology. We performed a laparoscopic low anterior resection. Histopathological evaluation showed unexpectedly actinomycosis. The patient received in addition antibiotics (cephalosporine, metronidazole), and could be discharged on the 12th postoperative day. Ten months later, there was no recurrence.
