Responses of Neural Elements in Experimentally InducedCarcinoma of the Hamster Tongue: An ImmunohistochemicalStudy Using Antibodies to Neurofilament Protein (NFP) andGlia-Specific S-100 Protein. Izumi K, Maeda T. Jpn J OralMaxillofac Surg 38:896, 1992

Innervation of carcinomas induced by application of9,10­dimethyl-I,2-benzanthracene (DMBA) was investigated inthe hamster tongue by using immunohistochemistry fordemonstration of neurofilament protein (NFP) and glia-spe­cific S·100 protein. The tumors were well-differentiatedsquamous cell carcinomas showing cordlike invasion of theunderlying fibrous tissue and muscle layer. The characteristicfeature of the innervation was the extreme scarcity of NFPand S-100 protein-irnmunopositive neural elements seen inthe stroma and around blood vessels of the carcinomas. Thefew NFP-positive neural elements that were observed in thecarcinoma invading zone were very fine and did not bearany relation to blood vesselsor tumor nests. Unlike calcitoningene-related peptide-positive nerves, which were intenselypositive in arterioles in the surrounding muscle layer, a densedistribution of S-100 protein-positive neural elements wasnot seen around .the abundant arterioles in the carcinoma­invading zone. The results suggest a high pain threshold andthe absence of an autoregulatory mechanism in the bloodvessels of the carcinoma tissue.-T. NAKAJIMA

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 re­ported in various series of major head and neck surgery pa­tients undergoing therapeutic cancer surgery. The role in theseinfections of facultative and aerobic gram-negative bacilli isuncertain. Even though these are common isolates in infec­tions in this group of patients, arninoglycoside prophylaxis,in addition to prophylaxis directed against anaerobes andgram-positive organisms, has resulted in an insignificantchange in infection rates. There have been a number ofstudieson the effect of prophylactic antibiotics in head and neckcancer surgery patients and, after review of these, there issome concern whether these antibiotics are therapeutic orprophylactic. There is no generally accepted practice of pro­phylaxis in patients undergoing cancer surgery of the upperaerodigestive tract . It has been well documented that pro­phylaxis is generally effective. A review of the literature re­vealed that single dose prophylaxis was of no effect whengiven more than 3 hours after bacterial inoculation subcu­taneously into rats, but was of maximum effect when ad­ministered immediately before the bacterial challenge. Thesestudies in rats were substantiated by studies in humans byStone, in which he showed ccfazolin given both preoperativelyand postoperatively was more effective than the same agentgiven postoperatively only. Other than this critical periop­erative period ofeffective antibiotic levels, several other prin­ciples apply to antibiotic prophylaxis in surgery. Tissue levels

of antibiotics should be maintained throughout the operation.Antimicrobial spectrum ofthe agent used should include mostall of the expected pathogens (the agent may not be the agentofchoice for therapy ofinfections at that given site.) It shouldbe nontoxic and inexpensive. It should be given sufficientlyclose in time to the surgery to preclude the development ofresistant flora preoperatively. The duration of prophylaxisshould be minimized for reasons of acquired resistance, ex­pense, and toxicity. The authors evaluated cefamandole inhead and neck cancer surgery patients in which the mucousmembrane of the aerodigestive tract was violated. The studywas placebo-controlled, double-blinded, and randomized.The initial dose of prophylaxis was given on call from theward to the operating room. The initial dose was 2 g, followedby I g 4 hours later, and I g 8 hours after the initial dose.Patients were evaluated for evidence of wound infection orrespiratory infection. Wounds were graded on a scale of0 to3, with the 0 being normal healing and 3 being purulentdischarge or dehiscence. A wound infection for the purposeof 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; butthe study was stopped at 20 patients for ethical reasons be­cause of significant differences between the two groups.Wound infection developed in 27% of the antibiotic groupand 55% of the placebo group. Microbiology revealed a mixedflora. The duration of use of prophylactic antimicrobials hasover the years diminished progressively from prolonged (Iweek or more) to relatively brief. Previous studies have givenprophylactic antibiotics in major head and neck surgery fora duration as brief as 24 hours. In this study, 8 hours oftherapy was effective.There was twice the incidence of woundinfections in the control group, but the small number pre­cluded statistical significance. The study was stopped becauseof excessive morbidity in the placebo group.-E.L. MOSBY

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
