Infantile Digital Fibroma Treated With Mohs Micrographic Surgery 总被引:2,自引:0,他引:2
John G. Albertini MD Maj USAF MC Michael Jude Welsch MD CPT USA MC Leo A. Conger MD LTC USA MC Lester F. Libow MD COL USA MC Dirk M. Elston MD COL USA MC 《Dermatologic surgery》2002,28(10):959-961
BACKGROUND: Infantile digital fibroma (IDF) is a rare benign fibrous tumor of childhood that frequently recurs despite local excision. Conservative, nonsurgical management may result in regression and/or joint deformity. OBJECTIVE: To describe the histologic features of IDF and discuss a case excised using Mohs micrographic surgery (MMS). METHODS: Case report and review of the clinical, histologic, and ultrastructural features. RESULTS: Characteristic inclusion bodies of actin were identified with hematoxylin and eosin, Masson's trichrome, and rapid actin immunostain. The tumor was debulked and the majority was removed after one stage of MMS, except where the deep margin approached the joint space. The defect healed by secondary intention. At 2 years the patient had no recurrence or functional joint deformity. CONCLUSION: MMS is a surgical treatment option for IDF. 相似文献

Three unanesthetized rhesus monkeys, seated upright, were exposed to graded hypercarbia (30% carbon dioxide per hour) after 72 hours at 4 ± 0.5% CO2 in an environmental chamber with ambient pressure (4,300-foot elevation), oxygen tension, and temperature. Narcotic and lethal levels of CO2 were compared to those in three monkeys exposed to 30% CO2 per hour after 72 hours at ambient air in the same chamber. No significant difference was found between the two groups. When these data were compared to those in three monkeys from a previous study, restrained in the supine position, differences were significant for both narcosis and death, with upright animals more tolerant to CO2. These findings indicate that CO2 adaptation fails to extend tolerance to acute exposures to CO2; however, the upright position affords more protection than does the supine position. 相似文献

Summary We have presented an unusual case of benign lymphoid hyperplasia, which manifested as a cecal deformity in a 15-year-old boy.
The clinical manifestation may have been related to partial occlusion of the appendiceal orifice. In future cases of benign
lymphoid hyperplasia, colonoscopy may be diagnostic, and if it is used for continuing observation, may avert unnecessary surgical
procedures in children and young adults. 相似文献

Analysis of exercise-induced R wave amplitude changes in detection of coronary artery disease in asymptomatic men with left bundle branch block 总被引:1,自引:0,他引:1
Gregory S. Uhl USAF MC Major J.Andrew C. Hopkirk MRCP RAF Squadron Leader 《The American journal of cardiology》1979,44(7):1247-1250
The exercise electrocardiograms of 44 asymptomatic men with acquired left bundle branch block were analyzed for changes in R wave amplitude. Results were correlated with findings on selective coronary angiography. There were two subgroups: 7 men with significant angiographic coronary artery disease (Group I) and 37 with normal coronary angiograms (Group II). Exercise induced an increase in R wave amplitude in all seven men with coronary artery disease but in only 10 of the 37 men without significant coronary artery disease. This criterion thus had a sensitivity of 100 percent but a poor specificity of 73 percent, a predictive value of 41 percent and an accuracy rate of 77 percent for the diagnosis of coronary artery disease. The greater the increase in R wave amplitude the greater was the likelihood of some degree of left ventricular dysfunction as measured by wall motion abnormalities and elevated left ventricular end-diastolic pressure. The increase in R wave amplitude with exercise appears to be a sensitive test in identifying coronary artery disease in asymptomatic men with acquired left bundle branch block. 相似文献

Background. Surgery of the digit is facilitated with adequate hemostasis for visualization of the operative field. Several types of tourniquets have been used for this purpose, including glove fingers, Penrose drains, Marmed digital tourniquets, and standard pneumatic tourniquets.
Objective. To present a novel method to achieve hemostasis during surgery of the digit.
Materials. A slightly oversized sterile glove, a hemostat, and a pair of scissors.
Conclusion. We present a novel method to achieve hemostasis using a sterile glove and a hemostat, that allows the surgeon to methodically titrate the amount of compression necessary to attain a bloodless field while minimizing the risks of excessive pressures.
