Abstract
INTRODUCTION proximal perigraft endoleak (PPE) and graft migration are associated with significant morbidity and mortality. Objective data establishing correlation between neck anatomy and these complications are lacking. The aim of this study was to analyse the anatomy of the neck in order to find which variables were significantly associated with PPE and graft migration. METHODS one hundred and eighty-four patients underwent endovascular repair (EVR) of infrarenal AAA using an in-house custom-made stent graft (Gianturco stents plus Dacron). Thirty-one patients had PPE and fifteen had graft migration. Neck diameter was measured at the level of renal arteries and lower limit of the neck. Necks were classified according to shape. Neck angulation was measured from spiral computed tomography (CT) or magnetic resonance imaging (MRI) reconstructions, or angiograms. Thrombus or atheroma lining and presence of calcifications were recorded. RESULTS neck angulation was significantly greater in patients who had PPE (50+/-16, p=0. 0005) or graft migration (54+/-20, p=0.003), compared to patients who had none of these two complications (37+/-18). Neck diameter was significantly greater in patients with PPE (p=0.05). Incidence of PPE or graft migration was not significantly higher in the presence of a conical shape, thrombus or atheroma lining and calcifications. CONCLUSION neck angulation was the risk factor most significantly related to PPE and graft migration.

Abstract
BACKGROUND The sentinel lymph node is the first node or nodes to drain a cutaneous melanoma. Sentinel lymph node biopsy is performed to determine whether regional metastases are present. The authors' experience with the new technique of sentinel lymph node biopsy for melanoma of the head and neck is reported. PATIENTS AND METHODS During the period of January of 1992 to December of 1995, 58 consecutive patients were identified from the melanoma database who had localization of the sentinel lymph node for primary cutaneous melanoma of the head and neck. Techniques for identification of the sentinel node(s) include preoperative lymphoscintigraphy and intraoperative Lymphazurin dye (vital blue dye) and technetium-99m-labeled sulfur colloid injection around the primary tumor site with Neoprobe mapping. RESULTS Fifty-eight patients (13 female, 45 male), mean age 61 years, with melanoma of the head and neck with a mean Breslow thickness of 2.21 mm. (range, 0.82-6.87 mm.) and no regional lymphadenopathy underwent sentinel node mapping. The sentinel node was successfully identified in 55 patients (95 percent). Blue dye was visualized in 85 of 126 sentinel nodes excised (67 percent), whereas the remainder of the sentinel nodes were localized with the Neoprobe. Forty-nine patients who had successful mapping and sentinel node biopsy had no evidence of metastatic disease in the sentinel node or other nodes in the basin. Six of the fifty-five patients (11 percent) had evidence of micrometastatic disease, and all six had the sentinel node as the only site of metastasis. Five of six patients with micrometastases had a subsequent neck dissection and/or superficial parotidectomy. None of these patients had evidence of "skip metastases" with a negative sentinel node and higher level nodes positive for metastases. In total, 6 of the 18 sentinel nodes (33 percent) identified in these six patients contained micrometastatic disease, whereas none of the 139 other nodes sampled had any evidence of metastases. The exact probability that all six unpaired observations would consist of involvement of only the sentinel nodes is p = 0.0312. CONCLUSIONS By combining the two mapping techniques in patients with melanoma of the head and neck, the sentinel node(s) can be mapped and identified individually, similar to melanoma in other locations. The sentinel nodes have been shown to contain the first evidence of regional metastatic melanoma. This staging information can be used to plan therapeutic node dissections and adjuvant therapy that may have a survival benefit in patients with stage III melanoma of the head and neck. Lymphatic mapping can be used to make the surgical care of the melanoma patient more conservative, so that only those patients with solid evidence of regional node metastases are subjected to the morbidity and expense of a complete node dissection and the toxicities of adjuvant therapy.

Abstract
Laparoscopic nephrectomy is gaining popularity. Improved instrumentation is making surgery easier with fewer complications. Our first three laparoscopic nephrectomies using the Harmonic Scalpel were performed on two women and one man. The surgical indications were nonfunctioning kidneys (two left, one right) with hypertension in one patient and stone disease in two. The three patients had a mean age of 46.3 years. The average hospital stay was 4 days, the average operative time 3.7 hours, and the average blood loss 160 mL. No complications occurred. Patients resumed oral intake within 8 hours postoperatively. We found the Harmonic Scalpel easy and safe to use. It saved time, was cost effective, and was capable of easily controlling small-vessel bleeding. In conclusion, the Harmonic Scalpel could be used effectively for both dissection and bleeding control without suction or other instrumentation.

Abstract
OBJECTIVE To perform a cost analysis of the emerging technology of lymphatic mapping for patients with malignant melanoma. DESIGN A retrospective, computer-aided chart and financial cost and charge review of consecutive patients with the diagnosis of melanoma registered at a cancer center from December, 1995 to March, 1996. PARTICIPANTS 73 consecutive patients with the diagnosis of Stage 1 and 2 melanoma (cutaneous disease only) had nodal staging of their disease with either a sentinel node (SLN) biopsy or an elective complete node dissection (ELND). This was determined largely by patient choice and the protocol in operation at the time of the presentation of the patient to the clinic. OUTCOMES MEASURED There were no deaths in the series. Patient morbidity endpoints included rates of infection, incidence of extremity lymphedema, development of a seroma in the regional nodal basin wound and wound healing. Clinical outcome was measured by the ability to obtain complete nodal staging information with the new lymphatic mapping technology, and recurrence rates in the nodal basin after a negative SLN biopsy. Total charges, direct costs and total costs were calculated from all hospital, OR, pathology and lab charges. Professional fees were included in the analysis. RESULTS Group 1 patients (50) had melanomas greater than 0.76 mm in thickness treated with a wide local excision (WLE), lymphatic mapping and SLN biopsy under general anesthesia. Five patients (Group 2) had their procedure performed under a straight local anesthesia. Group 3 patients (18) had nodal staging performed with an elective node dissection. In Groups 1 and 2, if the SLN was positive for micrometastases, the patients were taken back to the OR for a complete node dissection. The total charges per patient were $13,835, $6,853 and $19,285, respectively. Significant dollar savings were achieved if the nodal staging could be accomplished with the lymphatic mapping technology (p = 0.001). Morbidity was significantly less in Groups 1 and 2 compared to Group 3. After a mean follow-up of three years, only one patient has recurred in a SLN negative basin. CONCLUSIONS With 38,300 new cases of melanoma diagnosed each year in the United States, a projected savings of $172 million per year (general anesthesia) and $350 million per year (local anesthesia) could be realized if this new mapping technology could be incorporated into the care of the melanoma patient. Patient morbidity is minimized, nodal staging is complete and patients return to work sooner. Recently approved adjuvant therapy can be applied in a selective fashion, treating only those patients in which a documented benefit has been obtained, saving the health care system more dollars. Initial investment in defining the technology was minimal.

Abstract
BACKGROUND Once individuals are diagnosed with malignant melanoma, they are at an increased risk of developing another melanoma when compared with the normal population. METHODS To determine the impact of an intensive follow-up protocol on the stage of disease at diagnosis of subsequent primary melanomas, a retrospective query was performed of an electronic medical record database of 2,600 consecutively registered melanoma patients. RESULTS Sixty-seven patients (2.6%) had another melanoma diagnosed at the time of presentation to the clinic or within 2 months (synchronous) and another 44 patients (1.7%) developed a second primary melanoma during the follow-up period (metachronous). For the 44 patients diagnosed with metachronous lesions, the Breslow mean tumor thickness for the first invasive melanoma was 2.27 mm compared with 0.90 mm for the second melanoma. The first melanomas diagnosed are thicker by an average of 3.8 mm (p = 0.008). The mean Clark level for the initial melanoma was greater than the mean level for subsequently diagnosed melanomas (p = 0.002). Twenty-three percent of the initial melanomas were ulcerated, whereas only one of the second primary lesions showed this adverse prognostic factor (p = 0.002). CONCLUSIONS Once individuals are diagnosed with melanoma, they are in a high-risk population for having other primary site melanomas diagnosed and should be placed in an intensive follow-up protocol consisting of a complete skin examination.

Abstract
One way to improve students' access to and retention in post-secondary degree progams is to assess their readiness for such programs accurately. To place deaf and hard-of-hearing students in preparatory courses and to determine their readiness for degree programs more accurately, a direct measure of writing was developed for deaf and hard-of-hearing students at a large technical university. The purpose of this study was to estimate the concurrent and predictive validity of this measure. The Test of Written English (Educational Testing Service, 1992) served as the criterion in the concurrent validity study, and student success in the university's gateway freshman composition course served as the criterion in the predictive validity study. Results provide evidence of the concurrent and predictive validity of the measure, supporting its use for course placement and early planning purposes.

Abstract
In semistructured interviews, 20 men and 20 women (10 deaf and 10 hearing) between the ages of 18 and 28 recalled instances of instrumental, social, and expressive writing from their childhood. In contrast to earlier research, we found that instrumental writing occurred as frequently between deaf children and their hearing parents as between deaf children and their deaf parents and that all homes with a deaf family member had telecommunication devices for the deaf(TTYs). Whereas all respondents engaged in some form of social writing, deaf respondents did less personal or expressive writing than their hearing peers. Implications for literacy instruction and further research are that (a) teachers should take advantage of the writing experience that students bring to the classroom, (b) writing should be used as a tool for learning and classroom communication, and (c) the effects of experience, genre, school setting, and technology on the writing of deaf students should be examined.

Abstract
Approximately 20 per cent of melanomas greater than 0.76 mm in thickness will metastasize to the regional lymph nodes if treated with wide local excision alone (WLE). Elective lymph node dissection (ELND) is associated with significant morbidity, which includes lymphedema, wound complications, and paresthesias of the extremity. An alternative operative approach uses selective lymphadenectomy with the identification of the sentinel node, defined as the first node in the lymphatic basin that drains the primary cutaneous site. This study consisted of 132 patients with melanomas greater than 0.76 mm. One hundred nine patients (83%) had histologic negative sentinel nodes, and 23 patients (17%) had one or more sentinel nodes positive for disease. In patients with metastatic disease, 30/35 (86%) sentinel nodes were positive, and 25/357 (7%) nonsentinel nodes were positive (P < 0.001). In 18 patients (78%) of the 23 patients with metastatic disease, the sentinel node was the only node positive, strongly suggesting that there is an orderly progression of metastases. Two patients developed metastatic nodal disease after removal of a negative sentinel node (false negative rate = 1.5). The mean follow-up was 1 year. Sentinel node histology reflects the histology of the remainder of the nodes in the lymphatic basin and "skip" metastases, defined as a negative sentinel node but positive nodes higher in the regional chain positive for metastases or an axillary recurrence after a negative sentinel node biopsy, are rare for malignant melanoma. Harvesting the sentinel node in patients with intermediate or greater thickness melanoma will, therefore, identify a subset of patients with metastatic disease who have the most to benefit from a complete node dissection. This surgical approach allows for complete pathological staging and therapeutic management of patients while significantly reducing expense and overall morbidity.

Abstract
Indirect tests of writing competency are often used at the college level for a variety of educational, programmatic, and research purposes. Although such tests may have been validated on hearing populations, it cannot be assumed that they validly assess the writing competency of deaf and hard-of-hearing students. This study used a direct criterion measure of writing competency to determine the criterion validity of two indirect measures of writing competency. Results suggest that the validity of indirect writing tests for deaf and hard-of-hearing baccalaureate-level students is weak. We recommend that direct writing tests be used with this population to ensure fair and accurage assessment of writing competency.

Abstract
BACKGROUND A novel surgical technique based on selective lymphadenectomy was used to stage 132 patients with intermediate and thick cutaneous malignant melanoma. Preoperative and intraoperative lymph node mapping techniques were used to ascertain regional lymph node basins at risk for metastasis, and to identify the first node(s) the afferent lymphatics encounter in the basin, defined as the "sentinel" node(s). It has been shown that the histology of the sentinel node reflects the histology of the rest of the nodal bain, and according to preliminary studies using this technique, the likelihood of bypassing the sentinel node(s) to "higher" level nodes is less than 2%. Epidemiologic studies indicate that the long-term survival of patients with melanomas of intermediate thickness or greater is significantly compromised if regional lymph nodes are involved. Yet, the utility of performing lymph node dissections for the purposes of staging only is controversial, not only because of the morbidity and expense of the procedure, but the lack of proven survival benefit. OBJECTIVE In the present study, we performed preoperative and intraoperative lymphatic mapping, harvested clinically normal sentinel nodes, and examined them for micrometastasis by light microscopy. Both conventional stains and immunocytochemistry for S-100 protein and HMB-45 antibodies were performed, and only those patients with documented micrometastasis received complete lymph node dissections. RESULTS The sentinel node(s) was identified in each of the patients. Micrometastatic disease was detected in 31 (23%) of the patients by selective lymphadenectomy, and the sentinel node(s) was the only node involved in 83% of the cases upon subsequent complete nodal dissection. CONCLUSION Our preliminary results suggest that selective lymphadenectomy following lymphatic mapping is an effective procedure for staging melanoma patients with lesions of intermediate thickness or greater. Our results indicate that sentinel lymph nodes may be successfully identified and harvested in the majority of patients, and that they may be examined for the first evidence of micrometastasis without the need of a complete nodal dissection. Information as to whether micrometastases are present in the sentinel node would be valuable in staging patients, and identifying candidates for complete nodal dissections. We are participating in a National Cancer Institute-sponsored multicenter trial to ascertain whether this surgical approach can impact on the recurrence rate and survival of patients with stage 1 and 2 melanoma.

Abstract
The incidence of malignant melanoma is increasing at a faster pace than that of any other cancer in the United States. It is estimated that people born in the year 2000 will have a 1:75 risk of developing melanoma sometime during his or her lifetime. Stimulated by novel lymphatic mapping techniques, the surgical care of the melanoma patient is evolving toward more conservative resections that can provide the same staging information but without the added morbidity of more radical surgeries. This approach promises to yield positive results in the age of health care reform, outcome measurements, and cost:benefit considerations.

Abstract
Traditionally, stab wounds violating the abdominal wall fascia led to exploratory celiotomy that was often nontherapeutic. In an attempt to limit the number of nontherapeutic celiotomies (NTC), we devised a protocol to prospectively study stab wounds violating the anterior abdominal wall fascia. Through protocol, abdominal stab wounds were explored in stable adults. If the anterior fascia was violated, paracentesis and, if necessary, peritoneal lavage was undertaken in the absence of previous abdominal surgery. If evisceration was noted, it was reduced and the patient lavaged. Fascial penetration was noted in 72 patients. 46 patients underwent celiotomy: because of shock/peritonitis in 8 (2 NTC), fascial penetration with a history of previous celiotomy in 7 (5 NTC), positive paracentesis in 20 (5 NTC), or positive lavage in 10 (4 NTC). One patient underwent late celiotomy without ill-effect after a negative lavage because she subsequently developed fever and localized peritonitis (ice pick injury to cecum). Eleven patients had evisceration; nine underwent celiotomy. Patients with abdominal stab wounds can be selectively managed safely. More than one-third with fascial penetration, some with evisceration, avoided exploration. Only one patient underwent delayed celiotomy and did so without detriment. Nontherapeutic celiotomy rates were highest in patients with previous abdominal surgery who, thereby, could not undergo paracentesis/lavage; excluding these patients, the nontherapeutic celiotomy rate was 17% (11/65) for those with fascial penetration.
