Timely administration of prophylactic antibiotics for major surgical procedures.
BACKGROUND: Prophylactic antibiotics (PA) given within 60 minutes before surgical incision decrease risk of subsequent surgical site infection. Nationwide quality improvement initiatives have focused on improving the proportion of patients who receive timely prophylactic antibiotics. STUDY DESIGN: This is a cohort study of major surgical procedures performed in 108 Veterans Affairs hospitals between January and December 2005. Using data from the External Peer Review Program and the National Surgical Quality Improvement Program, we examined factors associated with timely PA administration. Univariate and multivariable analyses were performed. RESULTS: There were 8,137 major surgical procedures: cardiac (2,664), hip and knee arthroplasty (3,603), colon (1,142), arterial vascular (606), and hysterectomy (122). Timely PA occurred in 76.2% of patients, 18.2% received them too early, and 5.4% received them too late. Early administration accounted for 79% of untimely PA. Differences in timeliness were seen by procedure type (68% to 87%; p < 0.0001), admission status (67% to 80%; p < 0.0001), and antibiotic class (65% to 89%; p < 0.0001). PA administration occurred in the operating room for 63.5% of patients. When PA administration occurred in the operating room, they were timely in 89% of patients, compared with 54% of patients where administration was outside the operating room (odds ratio, 7.74; 95% CI = 6.49 to 9.22). CONCLUSIONS: Early PA administration accounted for the majority of inappropriately timed PA. Efforts to improve performance on this measure should focus on administering antibiotics in the operating room.

Decision analysis of prophylactic mastectomy and oophorectomy in BRCA1-positive or BRCA2-positive patients.
PURPOSE: Young Ashkenazi Jewish women or those from high-risk families who test positive for BRCA1 or BRCA2 mutant genes have a significant risk of developing breast or ovarian cancer by the age of 70 years. Many question whether they should have prophylactic surgical procedures, ie, bilateral mastectomy and/or oophorectomy. METHODS: A Markov model was developed to determine the survival, quality of life, and cost-effectiveness of prophylactic surgical procedures. The probabilities of developing breast and ovarian cancer were based on literature review among women with the BRCA1 or BRCA2 gene and mortality rates were determined from Surveillance, Epidemiology, and End Results (SEER) data for 1973 to 1992. The costs for hospital and ambulatory care were estimated from Health Care Financing Administration (HCFA) payments in 1995, supplemented by managed care and fee-for-service data. Utility measures for quality-adjusted life-years (QALYs) were explicitly determined using the time-trade off method. Estimated risks for breast and ovarian cancer after prophylactic surgeries were obtained from the literature. RESULTS: For a 30-year-old woman, according to her cancer risks, prophylactic oophorectomy improved survival by 0.4 to 2.6 years; mastectomy, by 2.8 to 3.4 years; and mastectomy and oophorectomy, by 3.3 to 6.0 years over surveillance. The QALYs saved were 0.5 for oophorectomy and 1.9 for the combined procedures in the high-risk model. Prophylactic surgeries were cost-effective compared with surveillance for years of life saved, but not for QALYs. CONCLUSION: Among women who test positive for a BRCA1 or BRCA2 gene mutation, prophylactic surgery at a young age substantially improves survival, but unless genetic risk of cancer is high, provides no benefit for quality of life. Prophylactic surgery is cost-effective for years of life saved compared with other medical interventions that are deemed cost-effective.

Prophylactic antibiotics for cesarean section and surgical procedures.
Although prophylactic antibiotics are used frequently on women undergoing pelvic surgery, including cesarean section, they should be reserved for patients who have a significant risk of infection. Among such patients are those who have undergone vaginal hysterectomy or cesarean section after having been in labor with ruptured membranes. Prophylaxis should be limited to one to three doses of antibiotic, with the newer broad-spectrum antibiotics and combination antimicrobial agents reserved for more serious, established infections.

Comparison of deep wound infection rates using a synthetic dural substitute (neuro-patch) or pericranium graft for dural closure: a clinical review of 1 year.
OBJECTIVE: The need to repair dural defects has prompted the use of dura mater substitutes. Many synthetic materials have been used for dural closure. Neuro-Patch (B. Braun Médical S.A., Boulogne, France) is a nonabsorbable microporous fleece composed of polyester urethane that has been approved for human use by the European Union since 1995. To the best of our knowledge, no clinical series with Neuro-Patch have been published thus far, particularly with regard to septic complications. The aim of our study was to compare the safety of Neuro-Patch with that of pericranium graft with regard to postoperative wound infections. METHODS: This is a retrospective study of 1 year's experience including all patients who underwent dural plasty with a Neuro-Patch (n = 61) or pericranium graft (n = 63). The follow-up period was at least 12 months after surgery. Before wound infection rates in the two groups were compared, factors suspected of being risks for neurosurgical site infection were evaluated. RESULTS: Patient characteristics (mean age, neurological diagnosis), surgical procedures, prophylactic antibiotics, and risk factors for surgical infections (including duration of surgery, emergency, contaminated operations, and external cerebrospinal fluid drainage) were similar in the Neuro-Patch and pericranium groups. Deep wound infection rates in the Neuro-Patch and pericranium groups were 15 and 5%, respectively (P = 0.06), and cerebrospinal fluid leaks were significantly more frequent in the Neuro-Patch group (13 versus 1.6%, P < 0.05). CONCLUSION: The results of our investigations show that Neuro-Patch raised the risk of wound infection, as do foreign materials implanted in the body. Synthetic dural grafts should be reserved for when autologous grafts are not sufficient or possible. An extensive prospective multicenter randomized trial is needed to confirm our results.

Arguments against routine contralateral mastectomy or undirected biopsy for invasive lobular breast cancer.
BACKGROUND: Management of the contralateral normal-appearing breast in a patient with ipsilateral invasive lobular carcinoma (ILC) is controversial. METHODS: The case histories of patients with histologically proven ILC who underwent definitive surgery at our institution from 1978 to 1991 were retrospectively reviewed. RESULTS: Of the 419 women with ILC, 36 (8.6%) had bilateral cancer, with a cumulative risk of 10% at 10 years. Twenty-five (69%) of these cancers were suspected before operation. From 105 contralateral prophylactic surgical procedures, seven (64%) in-situ and four (36%) invasive cancers were detected. The age at presentation and multifocality of the index cancer were significantly different between patients with unilateral and those with bilateral cancers. No survival difference was noted between patients whose contralateral cancers were suspected clinically and those whose cancers were detected prophylactically. Survival rates between patients with unilateral versus bilateral cancers were also not different. However, patients with contralateral prophylactic surgery had a better prognosis than those with unilateral tumors and no prophylaxis. CONCLUSIONS: Ten percent of patients with ILC experienced bilateral cancers during a period of 10 years. Survival was not influenced by the development of a second cancer, but it improved with surgical prophylaxis.

[Prevention in familial breast cancer susceptibility].
First retrospective data show that hereditary Breast cancer risk can be positively influenced by prophylactic surgical procedures and hereby a thorough consultation seem to be an option for mutant gene carriers. A first evaluation of the women of 1050 high-risk families by the German Consortium "Hereditary Breast and Ovarian Cancer promoted by the German Cancer Aid (Deutsche Krebshilfe)" has shown that approximately 80% of the women concerned decide to participate in an intensive early detection--programme and only 5% of the women have decided to submit themselves to prophylactic surgical measures. This again shows how absolutely necessary the elaboration and evaluation of early detection measures within the different investigation projects are.

Factors associated with postoperative infection.
OBJECTIVE: We have developed and analyzed a large surgical prophylaxis database and now report the factors significantly associated with early infection, readmission due to infection, and death within 28 days of surgery. This study is intended to be a stepping-stone for further studies using our clinical database. DESIGN AND SETTING: A computerized database of 9,016 surgical patients from a 400-bed community hospital was examined. Multivariate logistic regression and tree-based modeling were used to identify factors associated with the outcomes. Factors considered included surgical procedure, prophylactic antibiotic, age, gender, serum creatinine, and albumin. RESULTS: 12.6% had an early infection, 2.5% were readmitted due to infection, and 2.5% died within 28 days. Most combination prophylactic antibiotics were associated with an increased probability of an early infection. Decreased albumin and increased age were associated with an increased probability of an early infection. Tracheostomy and amputations were associated with an increased probability of an early infection, whereas gallbladder and orthopedic procedures involving the arm were associated with a decreased probability. Factors associated with readmission due to infection included dialysis shunt, vascular repair, and an early infection. Factors associated with increased probability of death within 28 days included age, albumin, serum creatinine, and an early infection. Gallbladder procedures and obstetric-gynecologic procedures were associated with a decreased probability of death within 28 days. DISCUSSION: Older patients and those with a decreased albumin were most likely to have an early infection. To the extent that an early infection was a significant risk factor for readmission due to infection, the impact of age and albumin on the probability of readmission due to infection is demonstrated by their effects on early infections. Interestingly, albumin and age were significantly associated with death within 28 days, in addition to early infection, showing the predictive association between these factors and early death.

Founder BRCA 1 and 2 mutations among a consecutive series of Ashkenazi Jewish ovarian cancer patients.
OBJECTIVE: The purpose of this study was to describe the incidence of the three Ashkenazi Jewish founder genetic BRCA 1 and 2 mutations among an unselected, consecutive group of Ashkenazi Jewish ovarian cancer patients. MATERIALS AND METHODS: From 7/30/96 to 4/12/99, 92 Ashkenazi Jewish patients with histologically confirmed epithelial ovarian cancer had surgery. All of these patients had DNA extracted from 5-microm sections of their paraffin-embedded surgical specimen tissue blocks using the Qiagen QIAamp tissue extraction kit. A multiplex (triplex) polymerase chain reaction was performed to amplify fragments for the 185delAG, 5382insC, and 6174delT mutations. The products were hybridized with normal and mutant probes for each of the three mutations. All clinical data were collected retrospectively and statistical significance was evaluated using the chi(2) test or a two-tailed Fisher's exact test, depending on the sample size. RESULTS: There were 23 patients positive for one of the three founder BRCA mutations. Fourteen patients were positive for the 185delAG mutation, 2 patients were positive for the 5382insC mutation, and 7 patients were positive for the 6174 delT mutation (61, 9, and 30%, respectively). This represented a 25% incidence (95% CI: 16-34%) of one of the three founder BRCA mutations among our 92 Ashkenazi Jewish ovarian cancer patients. None of the patients was positive for more than one mutation. There was no statistically significant difference in parity, histology, grade, or stage between the BRCA founder mutation positive and negative patients. The difference between the percentage of mutation carriers among patients with one affected first-degree relative (13/22 or 59%) compared to those without at least one affected first-degree relative (10/70 or 14%) was highly significant (P = 0.001). CONCLUSIONS: Ashkenazi Jewish ovarian cancer patients represent a group with a high likelihood of being carriers of BRCA 1 and 2 genetic mutations, regardless of family history. As a result, all ovarian cancer patients who are of Ashkenazi Jewish descent should be counseled regarding BRCA 1 and 2 genetic screening, as well as the potential implications of these results for the patient as well as her relatives in terms of prognosis, screening, chemoprevention, and consideration of prophylactic surgical procedures.

Communication in genetic counselling for breast/ovarian cancer.
Cancer genetic counselling represents a very special situation of interaction between the geneticist and the counselee, marked by a number of specificities that account for its complexity. Cancer genetic counselling has multiple repercussions, such as identification of a deleterious genetic mutation associated with a high probability of developing breast and/or ovarian cancer, the implementation of preventive measures ranging from close surveillance to the decision to perform mutilating prophylactic surgical procedures, or the impact of the information on the other members of the counselee's family also concerned by the genetic risk. This chapter is based on a review of the literature that has been rapidly growing over recent years and on our clinical expertise as psycho-oncologists and geneticists. We will first present the reasons that make the information so critical. These reasons are both objective (complexity of the genetic information per se, difficulties of understanding the concept of risk) and subjective (information given to people with an emotionally charged family history and a perception of risks closely linked to their representation of cancer). At the same time, the counsellees are charged with the transmission of this information to members of their own family. We will then discuss the various modalities of communication in this setting. While unidirectional transfer of information from the geneticist to the counselee has been the preferred method in cancer genetics for a long time, a model based on patient-centered communication is more adequate in predictive medicine and allows shared decision making. In all cases, the different professionals involved in the process have to learn how to work in a performing cohesion. We also present the main guidelines on the subject and the various underlying objectives with regard to information delivery and the subject's personal experience. Although the psychological impact of genetic counselling consultations raises a number of questions, the results of preliminary studies are reassuring, demonstrating psychological benefits. However, a number of aspects concerning communication in predictive medicine remain to be investigated and improved.

Inguinal hernia after radical retropubic prostatectomy for prostate cancer: a study of incidence and risk factors in comparison to no operation and lymphadenectomy.
PURPOSE: The incidence, mechanisms and risk factors of inguinal hernia after radical retropubic prostatectomy are sparsely elucidated in the literature. We determined the rate of inguinal hernia after radical retropubic prostatectomy and compared it to the incidence in patients with prostate cancer who did not undergo operation or underwent only pelvic lymph node dissection. MATERIALS AND METHODS: We followed 375, 184 and 65 men who underwent radical retropubic prostatectomy plus pelvic lymph node dissection, pelvic lymph node dissection only and no surgery with respect to inguinal hernia for a mean of 39, 47 and 45 months, respectively. The prostatectomy group was also evaluated in regard to the potential risk factors of previous hernia surgery and post-prostatectomy anastomotic stricture. RESULTS: The incidence of hernia was 13.6%, 7.6% and 3.1% in the prostatectomy, lymph node dissection and unoperated group, respectively. The difference was statistically significant in the prostatectomy and unoperated groups according to the Mantel-Cox log rank test and Cox proportional hazards rate. Previous hernial surgery and post-prostatectomy anastomotic stricture were more common in patients with an inguinal hernia after prostatectomy. CONCLUSIONS: The incidence of inguinal hernia is clearly increased in men who have undergone radical retropubic prostatectomy plus pelvic lymph node dissection compared with those who undergo no surgery for prostate cancer. Inguinal hernia appears to develop more often in men with prostate cancer who undergo radical retropubic prostatectomy and pelvic lymph node dissection than in those who undergo pelvic lymph node dissection only. While surgical factors trigger hernial development, previous hernial surgery and post-prostatectomy anastomotic stricture may be important risk factors. In fact, the latter may largely explain the difference in the incidence of inguinal hernia in our lymph node dissection and prostatectomy groups. Prophylactic surgical procedures must be evaluated to address this problem.

The thoracic outlet syndrome as a cause of aneurysm formation, thrombosis, and embolization.
The thoracic outlet syndrome may have a serious vascular component consisting of subclavian artery aneurysm with possible thrombosis and embolization which can result in severe ischemic symptoms in the upper extremity, gangrene, amputation, and even hemiplegia. Four cases of subclavian artery aneurysm in association with thoracic outlet syndrome are presented. Two of the patients required surgical intervention because of thrombosis and embolization, while the other two had prophylactic surgical procedure to prevent those complications.

BRCA susceptibility genes--a review of current conservative management of BRCA mutation carriers.
Three options for the management of a patient carrying a deleterious mutation in the BRCA gene exist: close surveillance, chemoprevention and prophylactic surgical procedures. We aimed at reviewing the current knowledge on the conservative management of patients who are found to be carriers of the BRCA susceptibility genes. Recent literature in the English language was reviewed for publications containing the conservative management of BRCA mutation-carriers. Close surveillance for the breasts includes breast self-examination, clinical examination by a specialist and breast imaging techniques--mammography and magnetic resonance imaging. Ovarian surveillance includes pelvic examination, transvaginal ultrasonography and blood CA-125 measurements. Age at beginning of examinations and their frequency are discussed. Chemoprevention includes tamoxifen and oral contraceptives for breast and ovarian cancer prevention, respectively.

[Lymph node failure in epithelioma of the glottic floor treated by partial laryngeal surgery. Apropos of 432 patients].
The authors assessed ganglionic failure in a series of 432 cases of N0 M0 epidermoid carcinomas of the glottic floor following partial laryngeal surgery. The overall of ganglionic failure was 7.8%. This rate of failure is related to 64.7% death rate, i.e. 5.1% of the 432 patients under study. This retrospective study differentiates between primary ganglionic failure and secondary ganglionic failure. Primary ganglionic failure is the first local/regional carcinologic event to develop after treatment of any glottic lesion. Secondary ganglionic failure is related to isolated local failures. The percentage of primary ganglionic failure was 5.1%. It was responsible for deaths occurring in 54.5% of cases. The percentage of secondary ganglionic failure was 2.7% and it was responsible for deaths occurring in 83.3% of cases. Factors promoting ganglionic failure (real tumor extension, tumor infiltration, altered laryngeal mobility, local control and efficacy of retakes of local failures) are discussed. The importance of prophylactic surgical procedures guarding from ganglionic failure, such as the ipsilateral jugular-carotid and recurrent nerve approaches is emphasized. Although such procedures can be of aid in cases of T2 or T3 N0 M0 epitheliomas of the glottic floor, they present no alternative in the course of retake operations of local failures.

Use of prophylactic antibiotics in surgical procedures: peer review guidelines as a method for quality assurance.
Concomitant with the development of guidelines for the use of prophylactic antibiotics in surgery, the Veterans Administration undertook a survey of its surgical chiefs in which the likelihood of peer review guidelines being an effective method of quality assurance was assessed. The scope of the present problem was also assessed in terms of the misuse of antimicrobial agents in surgical units. The implications of this study for quality assurance are:(1) Chiefs of surgery can be influenced by peer review guidelines, but other sources can also have impact. (2) The control practices used by chiefs to influence their staffs are limited. (3) The mechanisms used by chiefs to monitor adherence to their policies are mostly informal. The implications of this study in relation to surgical antibiotic prophylaxis are: (1) The practices of surgical chiefs differ significantly from peer review guidelines. (2) The problem is far more serious for certain surgical procedures than for others. (3) Most misuse errors are errors of commission rather than omission.
