Possible bite-induced abscess and osteomyelitis in Lufengosaurus (Dinosauria: sauropodomorph) from the Lower Jurassic of the Yimen Basin, China.

We report an osseous abnormality on a specimen of the sauropod dinosaur Lufengosaurus huenei from the Fengjiahe Formation in Yuxi Basin, China. A gross pathological defect occurs on the right third rib, which was subjected to micro-computed tomographic imaging as an aid in diagnosis. The analysis of pathological characteristics and the shape of the abnormality is incompatible with impact or healed trauma, such as a common rib fracture, and instead suggests focal penetration of the rib, possibly due to a failed predator attack. The identification of characteristics based on gross morphology and internal micro-morphology presented by the specimen, suggests an abscess with osteomyelitis as the most parsimonious explanation. Osteomyelitis is a severe infection originating in the bone marrow, usually resulting from the introduction of pyogenic (pus-producing) bacteria into the bone. Micro-tomographic imaging of the lesion suggests a degree of healing and bone remodelling following post-traumatic wound infection with evidence of sclerotic bone formation at the site of pathological focus, indicating that L. huenei survived the initial trauma. However, as osteomyelitis can express through widespread systemic effects, including a lowering of immune response and overall condition, this disease may have been a contributing factor to the eventual death of the individual.

Isolation of presumptive Streptobacillus moniliformis from abscesses associated with the female genital tract.

We report three cases in which Streptobacillus moniliformis was isolated from abscesses. Abscess material in each case contained small, pleomorphic, gram-negative to gram-variable bacilli. Anaerobic blood agar cultures yielded pinpoint colonies adjacent to small gray-white colonies. The pinpoint colonies did not gram stain, and the gray-white colonies varied from gram-variable coccobacilli to long, curly, gram-variable rods. The pinpoint colonies microscopically resembled L-forms on Dienes-stained agar preparation. Subculture to serum-supplemented thioglycolate broth demonstrated "puff ball" colonies. Fatty acid profiles obtained with use of gas chromatography coupled with mass spectrometry showed major peaks for C16:0, C18:2, C18:1, and C18:0 fatty acids, a profile characteristic of S. moniliformis. Results of biochemical testing of each isolate were equivocal. S. moniliformis, bacterial L-forms, and common isolates from genital tract abscesses are discussed.

[Hyperbaric oxygen therapy in case of the neck diffuse phlegmon with very hard clinical course]. / Leczenie hiperbaria tlenowa w przypadku rozleglej ropowicy szyi o bardzo ciezkim przebiegu klinicznym.

A case of 56 year old woman, diabetic (non-diagnosed before), suffering from diffuse phlegmon of the neck and acute submucosal laryngitis as a peritonsillar abscess complication is presented. Tracheotomy, abscess tonsillectomy with evacuation of peritonsillar abscess and extensive skin incisions of the neck with separation of tissue layers followed by drainage were performed at the beginning of hospitalization. This was regarded as responsible for stopping the violent development of the disease and saving the life of patient. Pathological bacteria were Streptococci (anaerobic and aerobic). Apart from the application of antibiotics (piperacyl, amikin, metronidazole) the patient was treated by hyperbaric oxygen (pressure 2,5 ata, one hour per day, on 6-9 day of treatment). Furthermore she was treated with oxygen applied through the tracheotomy tube during 5 days. In the authors' opinion the early performance of surgical procedure is necessary in the phlegmon of the neck as in the presented case. It is to be remembered, that these patients may suffer from other diseases like diabetes, non-diagnosed earlier. It has been noticed that significant improvement may be obtained by using the hyperbaric oxygen in the treatment of such cases.

[The exceptional way of spreading of the parapharyngeal space abscess]. / Wyjatkowa droga szerzenia sie ropnia przestrzeni przygardlowej.

The authors described the exceptional way of spreading of the parapharyngeal space abscess. Succession of this process were hypostatic abscesses of the lumbo-sacral region. Incision and drainage parapharyngeal abscess and as well hypostatic abscesses pointed out the usefulness in treatment.
