A brief tool to assess capacity to consent for medical care among homeless individuals with problematic substance use: study protocol. Arch Public Health 2013; 71:11. [PMID: 23651056 PMCID: PMC3651044 DOI: 10.1186/0778-7367-71-11] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2012] [Accepted: 05/06/2013] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Public health care increasingly uses outreach models to engage individuals who are marginalized, many of whom misuse substances. Problematic substance use, together with marginalization from the health care system, among homeless adults makes it difficult to assess their capacity to consent to medical care. Tools have been developed to assess capacity to consent; however, these tools are lengthy and unsuitable for outreach settings. The primary objective of this study is to develop, validate, and pilot a brief but sensitive screening instrument which can be used to guide clinicians in assessing capacity to consent in outreach settings. The goal of this paper is to outline the protocol for the development of such a tool. METHODS/DESIGN A brief assessment tool will be developed and compared to the MacArthur Competency Assessment Tool for Treatment (MacCAT-T). As list of 36 possible questions will be created by using qualitative data from clinician interviews, as well as concepts from the literature. This list will be rated by content experts according to the extent that it corresponds to the test objectives. The instrument will be validated with 300 homeless adult volunteers who self-report problematic substance use. Participants will be assessed for capacity using the MacCAT-T and the new instrument. A combination of Classical Test Theory and advanced psychometric methods will be used for the psychometric analysis. Corrected Item-Total correlation will be examined to identify items that discriminate poorly. Guided exploratory factor analysis will be conducted on the final selection of items to confirm the assumptions for a unidimensional polytomous Rasch model. If unidimensionality is confirmed, an unstandardized Cronbach Alpha will be calculated. If multi-dimensionality is detected, a multidimensional Rasch analysis will be conducted. Results from the new instrument will be compared to the total score from the MacCAT-T by using Pearson's correlation test. The new instrument will then be piloted in real-time by street outreach clinicians to determine the acceptability and usefulness of the new instrument. DISCUSSION This research will build on the existing knowledge about assessing capacity to consent and will contribute new knowledge about assessing individuals whose judgment is impaired by substance use.

The use of thoracoscopy to enhance medical students' interest and understanding of thoracic anatomy. Ann Thorac Med 2012; 7:145-8. [PMID: 22924072 PMCID: PMC3425046 DOI: 10.4103/1817-1737.98847] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/31/2011] [Accepted: 03/30/2012] [Indexed: 11/20/2022] Open
Abstract
AIM: To develop a video-based educational tool designed for teaching thoracic anatomy and to examine whether this tool would increase students’ stimulation and motivation for learning anatomy. METHODS: Our video-based tool was developed by recording different thoracoscopic procedures focusing on intraoperative live thoracic anatomy. The tool was then integrated into a pre-existing program for first year medical students (n = 150), and included cadaver dissection of the thorax and review of clinical problem scenarios of the respiratory system. Students were guided through a viewing of the videotape that demonstrated live anatomy of the thorax (15 minutes) and then asked to complete a 5-point Likert-type questionnaire assessing the video's usefulness. Apart from this, a small group of entirely different set of students was divided into two groups, one group to view the 15-minute video presentation of thoracoscopy and chest anatomy and the other group to attend a 15-minute lecture of chest anatomy using radiological images. Both groups took a 10-item pretest and post-test multiple choice questions examination to assess short-term knowledge gained. RESULTS: Of 150 medical students, 119 completed the questionnaires, 88.6% were satisfied with the thoracoscopic video as a teaching tool, 86.4% were satisfied with the quality of the images, 69.2% perceived it to be beneficial in learning anatomy, 96.2% increased their interest in learning anatomy, and 88.5% wanted this new teaching tool to be implemented to the curriculum. Majority (80.7%) of the students increased their interest in surgery as a future career. Post-test scores were significantly higher in the thoracoscopy group (P = 0.0175). CONCLUSION: Incorporating live surgery using thoracoscopic video presentation in the gross anatomy teaching curriculum had high acceptance and satisfaction scores from first year medical students. The video increased students’ interest in learning, in clinically applying anatomic fact, and in surgery as a future career.

Abstract
BACKGROUND Our objective is to ascertain if preoperative and perioperative treatments affect the short- and long-term symptom frequency or symptom scores for dysphagia, regurgitation, and heartburn in patients with laparoscopic Heller myotomy for achalasia. METHODS From 1994 to 2008, 261 patients undergoing laparoscopic esophageal myotomy were enrolled prospectively. The diagnosis of classic achalasia was made on clinical history, barium swallow, endoscopy, and manometry. A validated symptom questionnaire and history was taken for each patient at the preoperative visit and at each postoperative visit. RESULTS In all, 261 patients had laparoscopic Heller myotomy during the study period. Preoperatively, 137 patients (62.3%) tried medications, 101 (38.7%) were treated with pneumatic dilation, and 29 (11.1%) were treated initially with at least one injection of botulinum toxin into the lower esophageal sphincter. In all, 134 patients (51.3%) received a Dor anterior fundoplication. On multivariate regression controlling for age and sex, preoperative dilation (p = 0.031), injection of botulinum toxin (p = 0.044), and a fundoplication (p = 0.005) were associated with significantly worse early postoperative dysphagia, with odds ratios of 2.11, 2.56, and 2.80, respectively; previous botulinum toxin injection was associated with worse late postoperative dysphagia (p = 0.001), regurgitation (p = 0.031), and heartburn (p = 0.049), with odds ratios of 5.24, 2.87, and 2.52, respectively. There was a trend for no fundoplication to be associated with late postoperative heartburn (p = 0.077) with an odds ratio of 1.80. CONCLUSIONS Many patients presenting for Heller myotomy have previously undergone a different form of treatment. Early postoperative dysphagia was affected by dilation, botulinum toxin injection, and fundoplication. Only botulinum toxin injection was associated with late symptoms.

Abstract
Platinum microcoils were placed in porcine lungs to determine the feasibility for use as a lung nodule marker. Using computed tomography (CT) guidance, the microcoils were successfully deployed in 17 out of 19 attempts. Coil deployment depth ranged from 7 mm to 34 mm below the pleural surface. Moderate pneumothorax was detected after 3 of 19 microcoil insertions. No hemothorax or significant pulmonary hemorrhage was noted. Fluoroscopic guided thoracoscopic resection was successful in 10 of 12 attempts. Platinum microcoils can be safely and easily deployed into the lung parenchyma with minimal complication risk, and can be used to guide subsequent thoracoscopic wedge resection.

A change in clinical practice: a partially stapled cervical esophagogastric anastomosis reduces morbidity and improves functional outcome after esophagectomy for cancer. Dis Esophagus 2008; 21:422-9.

Abstract
Cervical esophagogastric anastomoses are commonly used for reconstruction after esophagectomy because of the lower mortality rate associated with an anastomotic leak compared to intrathoracic anastomoses. However, cervical esophagogastric anastomoses have been criticized for their higher leak rates, stricture formation and greater need for later dilatations when compared with intrathoracic anastomoses. Multiple studies have looked at varying techniques to improve the outcome of the cervical esophagogastric anastomosis. This study was performed to determine whether a partially stapled (posterior stapled wall and anterior hand-sewn wall) anastomosis reliably reduced leaks and the need for later dilatation. From January 2001 to March 2006, 168 patients who underwent cervical esophagogastric anastomosis following esophagectomy (transhiatal or three-hole) for cancer were identified. Beginning in September 2003, the partially stapled technique was introduced and used in 79 patients. Clinical outcomes were compared to patients in whom hand-sewn technique was used (n = 89). Outcomes related to anastomotic leak, other hospital complications, length of stay, postoperative dilatations and survival were compared using Student's t-tests and chi-square tests (P < 0.05), as well as multiple regression analyses. An anastomotic leak occurred in 10 (12.7%) patients who received a partially stapled anastomosis. A hand-sewn anastomosis was complicated by an anastomotic leak in 24 patients (27.0%). This difference was statistically significant (P = 0.021). This lowered incidence of leak was associated with an earlier initiation of oral feeds (median 7 vs. 9.5 days, P < 0.001) and a reduction in hospital stay (median 10 vs. 15 days, P < 0.001). Furthermore, dysphagia associated with stricture requiring postoperative dilatations was markedly diminished in the stapled anastomosis [23 (31.3%) vs. 49 (55.1%), P = 0.001]. The partially stapled cervical esophagogastric anastomosis significantly decreased the incidence of postoperative anastomotic leaks and the need for postoperative dilatation to treat strictures compared to the hand-sewn anastomosis.

Abstract
OBJECTIVE Our primary objective was to evaluate demographic and causal factors of inhospital mortality for significant firearm-related injuries (i.e., those with an Injury Severity Score [ISS] > 12) in Canadian trauma centres. METHODS We analyzed data submitted to the Canadian Institute for Health Information (CIHI) in the National Trauma Registry for all firearm-injured patients for fiscal years 1999-2003. Univariate and bivariate adjusting for ISS and multivariate logistic regression were performed. RESULTS Men accounted for 94% of the 784 injured. In all patients, the percentages of self-inflicted, intentional, unintentional and unknown injuries were 27.8%, 60.3%, 6.1% and 5.7%, respectively. The inhospital fatality rate was 39.8%, with 83% of fatalities occurring on the first day. Two-thirds of patients were discharged home. Univariate and adjusted analysis found that ISS, first systolic blood pressure (BP), first systolic BP under 100, first Glasgow Coma Scale (GCS) score, age over 45 years, self-inflicted injury, intentional injury and injury at home significantly worsened the odds ratio of death in hospital and that police shooting was relatively beneficial. BP under 100, age over 45 years and a low GCS score had an adjusted odds ratio of death of 4.12, 1.99 and 0.64 per point increase, respectively. The multivariate model showed that ISS, BP under 100, first GCS score, sex and self-inflicted injury were significant in predicting inhospital death. CONCLUSION A predominance of young men are injured intentionally with handguns in Canada, whereas older patients suffer self-inflicted injuries with long guns. The significant number of firearm deaths, largely in the first day, highlights the importance of preventative strategies and the need for rapid transport of patients to trauma centres for urgent care.

Abstract
OBJECTIVE The purpose of this study was to determine the satisfaction of members of an academic department who are funded by a Clinical Academic Service Contract (CASC), compared with those who are not. METHODS We mailed a satisfaction questionnaire designed to examine surgeons' perceived effect of CASCs on their participation in their division or department and on professional activities (research, teaching, clinical) to members of the surgery department who perform operative interventions. We analyzed responses from CASC and non-CASC members, using t tests for continuous variables and chi-square tests for categorical variables. RESULTS Four of 9 operative divisions (cardiac, thoracic, neurosurgery, pediatric surgery) are CASC-funded, and 5 are not (general, plastic, otolaryngology, urology, vascular). The response rate after 3 mailings was 59%. CASC responders agreed on the need for the following: improved focus and resolution of issues (p < 0.001, p < 0.02); focus on developmental and future planning (p < 0.001); flexibility to change the level of participation in research, teaching and clinical activities (p < 0.001); recognition for academic and administrative activities (p < 0.002); opportunities to achieve career path goals (p < 0.002); more autonomy in research (p < 0.04); compensation for professional activities (p < 0.001); and increased leisure time (p < 0.004). Responders disagreed that morale was low (p < 0.001). They were satisfied with the following: professional activities (p < 0.019), increased research activities (p < 0.001), quality of research (p < 0.001), more presentations (p < 0.025), increased teaching time (p < 0.004) and ability to care for their patients (p < 0.001). CONCLUSION CASC responders were significantly more satisfied with their professional activities and more optimistic in their divisional roles than were non-CASC responders. Based on these results, all departmental members who perform operative interventions should consider being on a CASC.

Anterior fundoplication decreases esophageal clearance in patients undergoing Heller myotomy for achalasia. Surg Endosc 2007; 21:2178-82. [PMID: 17514394 DOI: 10.1007/s00464-007-9327-4] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2006] [Revised: 10/16/2006] [Accepted: 12/04/2006] [Indexed: 12/13/2022]
Abstract
BACKGROUND Anterior fundoplication (AF) following laparoscopic Heller myotomy (LHM) for achalasia may prevent esophageal leaks and gastroesophageal reflux but cause dysphagia. Our study attempts to determine the effect of AF on esophageal leaks, nuclear medicine esophageal clearance (EC), symptom frequency (SF), and Van Trappen symptom scores (SS) for dysphagia, regurgitation, and heartburn. METHODS Between 1995 and 2004, pre- and postoperative (2-12 months) EC, SF, and SS scores were compared in 95 patients undergoing LHM for achalasia with AF (n = 71) and without (n = 24) AF. RESULTS There were no leaks or deaths. Laparoscopic Heller myotomy decreased the frequency of postoperative dysphagia, regurgitation, and heartburn with AF (96% preoperation versus 6% postoperation, 94% versus 3%, 58% versus 6%) (p = 0.001) and without AF (100% versus 0%, 83% versus 0%, 50% versus 4%) (p = 0.001). Laparoscopic Heller myotomy improved all SS in both groups. There was no difference between postoperative dysphagia (1.38 +/- 0.64 versus 1.17 +/- 38) p = 0.06, regurgitation (1.17 +/- 51 versus 1.04 +/- 0.20) p = 0.08, and heartburn (1.29 +/- 62 versus 1.53 +/- 0.80) p = 0.185 scores between the AF and no-AF group, respectively. There is a trend toward improvement in dysphagia and regurgitation in the no-AF group. Laparoscopic Heller myotomy improved EC in the supine and upright positions in both groups of patients (p = 0.001). There was an improved mean change in EC (10 min upright) in the no-AF group versus the AF group (50.7% +/- 30.8 versus 29.7% +/- 30.2) p = 0.004. CONCLUSIONS Laparoscopic Heller myotomy improves esophageal transit and the frequency and severity of dysphagia, heartburn, and regurgitation in a safe manner. Patients without AF show a statistically better upright EC with a trend toward improved dysphagia and regurgitation.

Defining the Optimal Treatment of Locally Advanced Esophageal Cancer: A Systematic Review and Decision Analysis. Ann Thorac Surg 2007; 83:1257-64. [PMID: 17383322 DOI: 10.1016/j.athoracsur.2006.11.061] [Citation(s) in RCA: 53] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/09/2006] [Revised: 11/09/2006] [Accepted: 11/13/2006] [Indexed: 10/23/2022]
Abstract
BACKGROUND The objective of this study was to combine systematic review and decision analytic techniques to determine the optimal treatment strategy for patients with locally advanced esophageal cancer. METHODS We performed a systematic review of all randomized trials of patients with locally advanced esophageal cancer that included one of the following strategies compared with surgery alone: chemoradiotherapy followed by surgery, chemotherapy followed by surgery, or surgery with adjuvant chemoradiotherapy. Using the estimates of relative risk for mortality and overall quality of life we constructed a decision model. The outcome of interest was expected quality-adjusted life-years (QALY). RESULTS The meta-analysis showed for the first year, the relative risk (95% confidence interval) of death for treatments compared with surgery were 0.87 (0.75 to 1.02) for chemoradiotherapy followed by surgery, 0.94 (0.82 to 1.08) for chemotherapy followed by surgery, and 1.33 (0.93 to 1.93) for surgery with adjuvant chemoradiotherapy. The QALYs gained for surgery alone, chemoradiotherapy followed by surgery, chemotherapy followed by surgery, and surgery with adjuvant chemoradiotherapy strategies were 2.07, 2.18, 2.14, and 1.99, respectively. If the reduction in utility for multimodality treatment was increased to 21%, the QALYs gained for surgery alone, chemoradiotherapy followed by surgery, chemotherapy followed by surgery, and surgery with adjuvant chemoradiotherapy were 2.07, 2.03, 1.99, and 1.85, respectively. CONCLUSIONS Chemoradiotherapy followed by surgery appears to be associated with the best survival and the largest expected gain in QALYs. However, the improvement in quality-adjusted life expectancy is modest at 40 days, and surgery alone becomes the preferred strategy if the reduction in utility associated with multimodality treatment is increased to 21%.

Abstract
AIM OF THE PAPER The aim of this paper is to examine individualized health visiting care and compare it to corporate working within a consensual management style. Corporate working has been discussed and used in many different ways since the idea first came to light at the end of the 1980s. Resource management makes it an appealing model, however, analysing how corporate working functions in the practice setting reveals the complexity of this method of service provision. BACKGROUND This paper is based on a method of practice developed by health visitors in Haywards Heath, West Sussex, who implemented the process. The article examines individualized health visiting care and compares it to corporate working within a consensual management style. Important in this analysis are the elements of reflexivity, active listening, reflection and the application of 'praxis' within the corporate caseload approach. METHODS Rogers' evolutionary concept model was used to illuminate and explain the different ways of delivering the health visiting service. FINDINGS There are benefits in working corporately: shared workload, increased professional support and improved accountability. Alongside the integrated supervision of this model is the opportunity offered to practitioners to innovate. This offsets any initial difficulty experienced in setting up this method and makes it a worthwhile change of style in health visiting practice. Improved service delivery, enhanced professional growth and increased opportunity for public health work can be demonstrated as outcomes of this model. For professionals this method may prevent 'burn-out', enhance practice and increase innovation in health visiting practice. Using this method as a blueprint, practitioners can develop their own style of corporate working that offers a service that is equitable, proactive, efficient and accessible to clients.

Abstract
Because the electrocardiograms (ECGs) of patients with symptoms suggesting an acute thrombotic coronary occlusion are typically read by physicians relatively inexperienced in this skill, it is important to develop automated decision support. A Thrombolytic Predictive Instrument (TPI) is now available along with the standard diagnostic software in a commercially available electrocardiograph. This study evaluates the performance of the predictive software in comparison to both an expert cardiologist and standard diagnostic software. True sensitivity and specificity cannot be determined because acute coronary angiography was not performed. The specificities determined by this study were excellent (98% and 99%), and the sensitivities were very good (72% and 78%). These results that the TPI will be only rarely applied to patients who do not indeed have an acute coronary thrombosis. However, the reasons for even this small number of presumably falsely TPI positive patients should be determined and analyzed. It is unlikely that alterations of the thresholds for TPI activation will significantly improve on this very good level of sensitivity, without prohibitively decreasing specificity.

Abstract
The standard method for performing electrocardiogram (ECG) recordings presents a challenge to technicians because of the need to correctly position the individual precordial electrodes according to 6 bony thoracic landmarks. A proposed new method using a 6-lead ECG BELT for precordial application was compared to the standard method to determine the level of agreement among automated interpretations. A comparison of automated interpretations from repeat standard recordings served as the control. Results indicate that BELT and standard automated interpretations disagreed significantly more frequently than repeat standard recording automated interpretations of the cardiac rhythm. The BELT's most obvious weakness was the inability to obtain a recording with a stable ECG baseline, triggering automated detection of "baseline artifact or wander," and requiring a repeat recording. These findings suggest that the ECG BELT is not adequate for clinical application in its current form.

Abstract
The objective of the study was to evaluate a shortened osteoporosis quality of life questionnaire (OQLQ) in osteoporotic women with back pain due to vertebral fractures. From the longer 30-item OQLQ (four to nine items per domain) we created the mini-OQLQ by choosing the two items with the highest impact in each of five domains (symptoms, physical function, activities of daily living, emotional function, leisure). We administered the OQLQ, the Sickness Impact Profile, the SF-36 and the Brief Pain Index to patients at baseline, after 2 weeks and after 6 months. The intraclass correlations between baseline and the 2-week follow-up for the five mini-OQLQ domains ranged from 0.72 to 0.86. Cross-sectional correlations between the domains of the mini-OQLQ and other health instruments were moderate to large (0.35-0.80) and greater than predicted. The mini-OQLQ items showed moderate to large correlations with items omitted from the shortened questionnaire (0. 44-0.88). Correlations between the OQLQ domains and the other three instruments were greater than those of the mini-OQLQ, and partial correlations between OQLQ items omitted from the mini-OQLQ and the other three instruments after considering mini-OQLQ items were substantial (0.19-0.71) and statistically significant. Sample sizes of less than 200 per group should be required to detect minimally important differences in parallel-group clinical trials. Longitudinal correlations between the mini-OQLQ and the other measures were often significant but generally lower than predicted (0.10-0.49). The partial correlations revealed that the omitted items explained a significant portion of the longitudinal variance in each domain. We conclude that in a selected group of patients with back pain caused by vertebral fractures, the mini-OQLQ demonstrated good discriminative and adequate evaluative properties. The mini-questionnaire should be useful in clinical settings.

Abstract
The btuB gene product from Escherichia coli is a 66.5-kDa integral outer membrane protein required for high-affinity uptake of cyanocobalamin and the translocation of E group colicins and colicin A. Efficient purification of overexpressed BtuB containing stoichiometric levels of bound lipopolysaccharide has been achieved through the extraction of the outer membrane with nonionic detergent followed by ion-exchange chromatography. Analysis of far UV circular dichroism spectra indicates a predominantly beta-sheet secondary structure (76 +/- 4%) with a low alpha-helical content (15 +/- 3%), providing the first direct evidence for secondary structure models derived from sequence and hydropathy analysis. Characterization of the octylglucoside-solubilized receptor by sedimentation equilibrium and sedimentation velocity analysis reveals a monodisperse protein-detergent complex of approximately 89 kDa with a sedimentation coefficient of 4.7 S which, after correction for bound detergent, indicates that BtuB is purified as a monomer. BtuB binds vitamin B12 with a stoichiometry of approximately 1:1, as observed by a shift in the sedimentation profile of the vitamin to the much faster velocity observed for the protein-detergent complex. The preincubation of colicin E3 with stoichiometric levels of BtuB protects susceptible strains from the lethal effects of the colicin and results in a complex with a sedimentation coefficient appropriate for a BtuB-detergent-colicin E3 complex, demonstrating that monomeric BtuB retains high affinity for this particular ligand after isolation.

Abstract
OBJECTIVE To evaluate the clinical utility of a new portable ultrasound device (PUD) in the management of intermittent catheter programs in patients with neuropathic bladder. DESIGN Intervention study using randomized control trial. SETTING Tertiary care center providing inpatient and ambulatory rehabilitation services to persons with neurologic disabilities. PARTICIPANTS Thirty-eight inpatients and outpatients with neuropathic bladders requiring intermittent catheterization. MAIN OUTCOME MEASURES Mean frequency of intermittent catheterization, mean number of episodes of overdistension, and patient satisfaction as measured with a Patient Satisfaction Questionnaire. RESULTS The mean frequency of catheterization per day was reduced in the PUD group in comparison with controls (2.99 vs 4.12, p = .026). The number of episodes of overdistension was also reduced in the PUD group but did not reach statistical significance (12.45 vs 14.76, p = .61). Subjects generally expressed satisfaction with the PUD, with 16 of 18 patients at least somewhat satisfied with the device. CONCLUSION The PUD is a useful tool for clinicians in patients undergoing intermittent catheterization programs that can reduce the number of required catheters. It is associated with a high degree of patient satisfaction.

Abstract
The authors present 20 microvascular flaps based on arteriovenous perfusion, harvested from the distal anterior forearm, and configured in three different designs. Indications were small palmar, dorsal, and commissural defects, when other conventional procedures were not available; problematic cases of open reduction internal fixation with skin defect; and when aggressive rehabilitation was needed. The follow-up varied between 6 and 28 months. Some degree of vascular congestion was observed in 100 percent of the flaps, and those changes were classified in a progressive form. Coverage was judged as stable, thin, and pliable in 75 percent of the cases in the series; aggressive rehabilitation was started promptly in all cases where this was possible. On average, an additional 2.4 hr were required for the original procedure. This flap demands little technical expertise for any microsurgical surgeon, and does not sacrifice any important donor vessel. The flap should not be followed-up by conventional monitoring methods instead, simple palpation of the pulse, Doppler auscultation, or PPG are required.

Abstract
BACKGROUND AND METHODS A comparison of total vs. partial laparoscopic fundoplication was conducted in 89 patients from July 92 to June 96. Parameters examined were operating room (OR) times, conversion rates, and perioperative complications. Patient satisfaction, control of symptoms, and late complications were assessed by follow-up at a mean of 6 and 15.4 months. RESULTS There were six conversions to open surgery resulting in 48 laparoscopic total (LTF) and 35 laparoscopic partial (25 anterior and 10 Toupet) fundoplications (LPF). The following results were obtained for each respectively: preop Demeester score 44 vs. 39; OR time 2.9 vs. 2.5 hours; length of stay 3.6 vs. 4.1 days; early morbidity 25% vs. 1%. There were no mortalities. At a mean follow-up of 6 months, new-onset dysphagia was present in 8 (17%) vs. 2 (8%), respectively (NS), and both total and partial fundoplications appeared successful in controlling symptoms (98% vs. 97%). At a mean follow-up of 15.4 months, heartburn was resolved or improved in 76% vs. 87% (NS); regurgitation was improved or resolved in 93% vs. 93%; and patient satisfaction with the procedure was present in 93% vs. 97% (NS). Persistent dysphagia was present in 7.3% vs. 10.3% (NS) of patients. Early satiety was present more often in the partial fundoplication group (56% vs. 83% P = .03). CONCLUSIONS Early follow-up suggests equal efficacy in controlling symptoms and in achieving patient satisfaction. A 6-month follow-up suggested a higher incidence of new dysphagia in the total fundoplication group; however, at 15-month follow-up there was no significant difference.

Abstract
BACKGROUND The frequency and causes of gastrointestinal complications following esophagectomy for malignancy are unknown. PATIENTS AND METHODS We reviewed 295 esophagectomies performed for malignancy between January 1980 and September 1994 in order to determine the frequency and causes of early and late gastrointestinal complications. RESULTS Compared to transhiatal and left thoracoabdominal esophagectomies, esophagectomies carried out through a right posterolateral thoracotomy with cervical esophagogastric anastomosis had a higher incidence of delayed gastric emptying (11%), pneumonia (26%), and hospital death (9%). The same operation had a higher incidence of gastroesophageal reflux (20%) and dysphagia requiring esophageal dilatation (53%). We found no independent effect of gastric drainage procedures, feeding jejunostomy, preoperative radiotherapy, pathology, or age on these outcomes. Women had no operative mortality, but a higher incidence of gastroesophageal reflux and diarrhea following esophagectomy. CONCLUSIONS Surgical techniques aimed at improving gastric emptying following esophagectomy for cancer should improve operative morbidity and mortality.

Abstract
OBJECTIVE To learn about the physical, emotional, and social limitations experienced by postmenopausal women who have back pain due to vertebral fractures resulting from osteoporosis. METHODS We conducted a cross-sectional survey of female patients with persistent pain due to vertebral fractures. RESULTS Respondents had a mean (+/- SD) bone density of 0.87 +/- 0.13 gm/cm2 and a mean (+/- SD) of 2.84 +/- 2.18 fractures. Disability was identified in pain, movement, activities of daily living, and emotion. There was a poor correlation between quality of life and findings on radiography or densitometry. CONCLUSION To evaluate the effects of osteoporosis on a patient's functional status, direct questioning is required.

Abstract
A series of (aminoalkoxy)chromones has been prepared, members of which bind potently (16-100 nM) at the sigma binding site and bind weakly (greater than 1000 nM) at the dopamine D2 receptor and 33 other receptors, second messenger systems, and ion channels. At the sigma receptor, the preferred position of attachment for the aminoalkoxy side chain to the chromone ring followed the rank order: 7-position greater than 5-position greater than 6-position. Chromones that contained a 2-substituent that was not coplanar with the chromone ring system showed improved binding over compounds with coplanar substituents. The most potent compound at the sigma site, 7-[[7-(4-hydroxypiperidyl)heptyl]oxy]-2-phenylchromone (74), had receptor affinities (IC50) of 16 nM at the [3H]DTG site, 19 nM at the [3H]-(+)-3-PPP site, and 4000 nM (Ki) at the dopamine D2 receptor. The most selective compound examined, 6-[[6-(4-hydroxypiperidyl)hexyl]-oxy]-2-cyclopentylchromone (58), exhibited IC50s of 51 nM at the [3H]DTG site, 55 nM at the [3H]-(+)-3-PPP site, and 21,000 nM (Ki) at the dopamine D2 receptor. Compound 44 (6-[[6-(4-hydroxypiperidyl)hexyl]oxy]-3-methylflavone, NPC 16377) was systemically effective (ip and po) in two behavioral models predictive of antipsychotic compounds and systemically active in animal models of ischemia.
