Izumi K, Maeda T. Jpn J Oral Maxillofac Surg 38:896, 1992 Innervation of carcinomas induced by application of9,10- dimethyl-I,2-benzanthracene (DMBA) was investigated in the hamster tongue by using immunohistochemistry for demonstration of neurofilament protein (NFP) and glia-spe- cific S·100 protein. The tumors were well-differentiated squamous cell carcinomas showing cordlike invasion of the underlying fibrous tissue and muscle layer. The characteristic feature of the innervation was the extreme scarcity of NFP and S-100 protein-irnmunopositive neural elements seen in the stroma and around blood vessels of the carcinomas. The few NFP-positive neural elements that were observed in the carcinoma invading zone were very fine and did not bear any relation to blood vesselsor tumor nests. Unlike calcitonin gene-related peptide-positive nerves, which were intensely positive in arterioles in the surrounding muscle layer, a dense distribution of S-100 protein-positive neural elements was not seen around .the abundant arterioles in the carcinoma- invading zone. The results suggest a high pain threshold and the absence of an autoregulatory mechanism in the blood vessels of the carcinoma tissue.-T.

Antibiotic Prophylaxis in Head and Neck Cancer Surgery. Saginur R, Odell TF, Poliquin JF. J Otolaryngol 17:2, 1988 Postoperative infection rates of 20% to 80% have been re- ported in various series of major head and neck surgery pa- tients undergoing therapeutic cancer surgery. The role in these infections of facultative and aerobic gram-negative bacilli is uncertain. Even though these are common isolates in infec- tions in this group of patients, arninoglycoside prophylaxis, in addition to prophylaxis directed against anaerobes and gram-positive organisms, has resulted in an insignificant change in infection rates. There have been a number of studies on the effect of prophylactic antibiotics in head and neck cancer surgery patients and, after review of these, there is some concern whether these antibiotics are therapeutic or prophylactic. There is no generally accepted practice of pro- phylaxis in patients undergoing cancer surgery of the upper aerodigestive tract . It has been well documented that pro- phylaxis is generally effective. A review of the literature re- vealed that single dose prophylaxis was of no effect when given more than 3 hours after bacterial inoculation subcu- taneously into rats, but was of maximum effect when ad- ministered immediately before the bacterial challenge. These studies in rats were substantiated by studies in humans by Stone, in which he showed ccfazolin given both preoperatively and postoperatively was more effective than the same agent given postoperatively only. Other than this critical periop- erative period of effective antibiotic levels, several other prin- ciples apply to antibiotic prophylaxis in surgery. Tissue levels 99 of antibiotics should be maintained throughout the operation. Antimicrobial spectrum of the agent used should include most all of the expected pathogens (the agent may not be the agent of choice for therapy of infections at that given site.) It should be nontoxic and inexpensive. It should be given sufficiently close in time to the surgery to preclude the development of resistant flora preoperatively. The duration of prophylaxis should be minimized for reasons of acquired resistance, ex- pense, and toxicity. The authors evaluated cefamandole in head and neck cancer surgery patients in which the mucous membrane of the aerodigestive tract was violated. The study was placebo-controlled, double-blinded, and randomized. The initial dose of prophylaxis was given on call from the ward to the operating room. The initial dose was 2 g, followed by I g 4 hours later, and I g 8 hours after the initial dose. Patients were evaluated for evidence of wound infection or respiratory infection. Wounds were graded on a scale of 0 to 3, with the 0 being normal healing and 3 being purulent discharge or dehiscence. A wound infection for the purpose of this study was defined as a wound with purulent drainage. Patients were followed for a minimum of 4 weeks postop- . eratively. The study was planned to include 40 patients; but the study was stopped at 20 patients for ethical reasons be- cause of significant differences between the two groups. Wound infection developed in 27% of the antibiotic group and 55% of the placebo group. Microbiology revealed a mixed flora. The duration of use of prophylactic antimicrobials has over the years diminished progressively from prolonged (I week or more) to relatively brief. Previous studies have given prophylactic antibiotics in major head and neck surgery for a duration as brief as 24 hours. In this study, 8 hours of therapy was effective.There was twice the incidence of wound infections in the control group, but the small number pre- cluded statistical significance. The study was stopped because of excessive morbidity in the placebo group.-E.L.

Cholesterol Granuloma of the Maxillary Antrum. GatlandDJ, Young RP, Jeffrey 11M. J Otolaryngol 17:131, 1988
"Cholesterol granula" is a histologic term, not a clinicaldiagnosis. It is not related in any way to cholesteatoma. It isa foreign body reaction to the presence ofcholesterol crystalsand shows no abnormal growth of epithelium. It is a lesionwhich is well recognized in the middle ear, mastoid area,testes, fallopian tube and arterial atheroma, and followinghemorrhage into thyroid'adenomas, Their behavior has beencharacterized as ranging from benign to destructive. Theredoes not appear to be any cause that has been demonstratedand they do not respond to conservative therapy. There doesnot appear to be any correlation between the duration oftheir symptoms and their benign or destructive behavior, assome patients have been asymptomatic while the majorityhave had symptoms that have ranged from 6 months to 6years. The symptoms occurring appear to be nonspecific,being predominantly nasal obstruction. The histologic appearance does not vary with the tissue in which it occurs.Review of the literature suggests that a closed space with
poor ventilation or drainage is the prime factor in their development. It is felt that a chronic effusion of hemorrhagethen leads to cholesterol precipitation. The traditional viewis that the cholesterol crystals are derived from the hemorrhage. Some feel that slow lymph drainage might also besignificant. The case report on this patient showed that thelesion occurred in a 70-year-old white male with a 6-weekhistory ofprogressive painless swelling ofhis right cheek, hischief complaint being that his denture no longer fit. Therewere no other symptoms and clinical examination, except aspertained to the area of the lesion, was within normal limits.There was a non tender spongy swelling of the right cheekand a cystic 5 X 3-cm swelling replacing the upper alveolusand hard palate on the right side. A plain film radiographshowed a large soft tissue mass occupying the right maxillaryantrum with thinning and ballooning out of the superior andlateral walls with destruction of the hard palate. These filmswere consistent with carcinoma. Tomograms were orderedthat showed that the bony margins of the antrum appearedto be intact. The patient was taken to surgery where aspirationproduced 60 mL of brown fluid and a biopsy of the soft tissueshowed typical features ofa cholesterol granuloma with numerous cholesterol clefts surrounded by foreign body-typegiant cells embedded in granulation tissue. The antrum wasfound to be filled with pallapoidal material and there wasinspissated mucus present on the inferior and medial walls.The wallswere found to bedeficient inferiorly and posteriorly.Contents of the antrum were completely stripped and anintranasal antrostomy created. Histologic examinationshowed similar features to that of the frozen biopsy and confirmed that the lesion had eroded bone. There was no reportedhistory of trauma as a source for the hemorrhage.-E.L.MOSBY
