Morphologic characteristics of primary nonperforative intestinal blast injuries in rats and their evolution to secondary perforations.

Five hundred and fifty Wistar rats were investigated to determine the frequency of secondary intestinal perforations after exposure to nonperforating blasts and the evolution of the morphological changes from hematoma through to necrosis and gangrene. The animals were observed at different times for a period of 14 days from the moment that the injury was inflicted. Microscopic findings showed that alterations began in the mucosal layer where they were most extensive, then spread to the submucosal layer, muscular layer, and serosal layer, respectively. Examination of the intestinal wall revealed an evolution of the injury from hematoma to necrosis to gangrene, resulting in secondary intestinal perforation. The secondary wounds had centrifugal patterns, opposite those of the original wound pathways. Based on these observations, the mechanism of evolution of primary nonperforating intestinal blast injury into secondary intestinal perforations is presented.

[A compound odontoma].

Compound odontoma is a malformation manifested as a localized lesion before a non-erupted or displaced tooth consisting of numerous small tooth-like components. The lesion develops asymptomatically. The recognition of its clinical features helps the prevention of deformities and caries in the adjacent teeth by an on time and adequate surgical treatment.

[Idiopathic histiocytosis of the jaw].

Principal features of Idiopathic Histiocytosis (IH) are discussed in relation to five cases treated in the Department of Maxillofacial Surgery VMA. Clinical symptoms of the disease are known. Radiology of the bones and bone scintiscans are of most importance for evaluation of extension of the disease. Surgery is treatment of choice. The major problem with IH in the jaws is, however, progressive mutilation of dental apparatus.

[Intraosseous schwannoma].

Neurogenic tumors, primary bone tumors, are rather exceptional; about 50 cases have been reported so far. The study reports a case of intraosseous schwannoma, a primary bone tumor, in a 20-year-old male patient, localized in the distal end of the right tibia.

Experimental soft tissue wounds caused by standard military rifles.

Soft tissue wounds were caused by penetration of a bullet through both thighs in 42 pigs, fired from N48, M70, M16A1 and FAL rifles at 50 meter range. Four comparable groups of wounds, consisting mainly of injured muscle, were examined. Primary debridement was carried out 5-6 hours following wounding, multiple muscle biopsies up to 40 mm sidewise of permanent wound channel were taken for HE and histochemistry. Primary contamination was traced using marker aerobic bacteria. Bullet velocities at impact and exit were measured and transfer of energy to liver tissue calculated when feasible. The condition of the bullet after exit was precised. The surgical estimation of tissue injury, the mass of excised tissue and microsections have served to evaluate the extent of tissue injury. For 22.5 cm mean channel length the most injury was caused by the FAL, followed by M16, M70 and M48 rifles in declining order. Local effects are ascribed to bullet tumbling, break-up and energy transfer of corresponding missiles. Correlation of surgical and pathology methods is discussed.

[Ochronosis--an autopsy case report].

The authors have presented a case of ochronosis, as the incidental finding during the autopsy of a female patient, aged 59 years. It was the case of suicidal drug poisoning. Ochronosis is a rare disease, with chronic benign course, but frequently followed by complications. Histopathological criteria for the diagnosis of this disease are described in detail.

[Myositis ossificans in recurrent synovial hemangioma of the knee].

A case of myositis ossificans in 15-year old boy that occurred as a complication of the recurrent synovia hemangioma of the left knee was presented. The alteration was diagnosed as: osteosarcoma, chondrosarcoma and chondromyxoid fibroma by the pathologists from other institutions. The diagnosis of myositis ossificans was established using numerous histochemical and immunochemical methods (PAS, PAS diastasis, Alcian blue, Masson trichrom, von Kossa, Azur A, Toluidin blue, Goldner, method by Peris, Citokeratin, S-100, NSE and Vimentin). The presence of zonal phenomenon, as the one observed in the presented case, is one of the most significant criteria for differentiation of myositis ossificans from osteosarcoma.
