Most estimates in the literature for the economic cost of treating a diabetic foot ulcer (DFU) are from industrialized countries. There is also marked heterogeneity between the complexity of cases considered in the different studies. The goal of the present article was to estimate treatment costs and costs to patients in five different countries (Chile, China, India, Tanzania, and the United States) for two hypothetical, but well-defined, DFUs at the extreme ends of the complexity spectrum. A co-author, who is a treating physician in the relevant country, was asked to choose treatment plans that represented the typical application of local resources to the DFU. The outcomes were pre-defined as complete healing in case 1 and trans-tibial amputation in case 2, but the time course of treatment was determined by each investigator in a manner that would be typical for their clinic. The costs, in local currencies, for each course of treatment were estimated with the assistance of local hospital administrators. Typical reimbursement scenarios in each country were used to estimate the cost burden to the patient, which was then expressed as a percentage of the annual per capita purchasing power parity-adjusted gross domestic product. There were marked differences in the treatment plans between countries based on the availability of resources and the realities of local conditions. The costs of treatment for case 1 ranged from Int$102 to Int$3959 in Tanzania and in the United States, respectively. The cost for case 2 ranged from Int$3060 to Int$188,645 in Tanzania and in the United States, respectively. The cost burden to the patient varied from the equivalent of 6 days of average income in the United States for case 1 to 5.7 years of average annual income for case 2 in India. Although these findings do not take cost-effectiveness into account, they highlight the dramatic economic burden of a DFU for patients in some countries.  相似文献

Introduction

Malignant Pleural Effusion (MPE) is a common terminal clinical problem in patients with advance cancer. Treatment options for MPE include observation, thoracocentesis, or pleurodesis. In the current study, we compared the effectiveness and safety of combined mechanical and chemical pleurodesis by Video Assisted Thoracoscopic Surgery (VATS) with chemical pleurodesis via intercostals tube alone, using talc as pleurodesis agent in both.

Material and methods

In this prospective study, diagnosed patients of MPE having Eastern Cooperative Oncology Group (ECOG) performance score 3 or less 3, expected life expectancy of more than 3 months, and having lung re-expansion after drainage were selected for pleurodesis. Patients with ability to undergo general anesthesia were considered for VATS assisted combined mechanical & chemical pleurodesis (Group A). In the remaining chemical pleurodesis was performed at bedside (Group B).

Results

The duration of this study was 1 year. The total number of patients was 30. There were 15 patients each in both the groups. Pleurodesis was achieved in 4.47?±?0.92 days in group A and 6.33?±?0.90 days in group B. This difference was highly significant (p?<?0.0001). Post procedural complaints were more or less same in both the groups.

Conclusion

Combined mechanical and chemical pleurodesis (VATS assisted) appears to be superior to chemical pleurodesis, as it offers less morbidity, lesser hospital stay, and complete response in follow up. This modality may be used in patients of MPE for palliation, who are fit for general/ regional anesthesia.  相似文献

Introduction and study aim

Natural orifice translumenal endoscopic surgery (NOTES) is an emerging surgical technique that requires a cautious adoption approach to ensure patient safety. High-fidelity virtual-reality-based simulators allow development of new surgical procedures and tools and train medical personnel without risk to human patients. As part of a project funded by the National Institutes of Health, we are developing the virtual transluminal endoscopic surgery trainer (VTEST?) for this purpose. The objective of this study is to conduct a structured needs analysis to identify the design parameters for such a virtual-reality-based simulator for NOTES.

Methods

A 30-point questionnaire was distributed at the 2011 National Orifice Surgery Consortium for Assessment and Research meeting to obtain responses from experts. Ordinal logistic regression and the Wilcoxon rank-sum test were used for analysis.

Results

A total of 22 NOTES experts participated in the study. Cholecystectomy (CE, 68 %) followed by appendectomy (AE, 63 %) (CE vs AE, p = 0.0521) was selected as the first choice for simulation. Flexible (FL, 47 %) and hybrid (HY, 47 %) approaches were equally favorable compared with rigid (RI, 6 %) with p < 0.001 for both FL versus RI and HY versus RI. The transvaginal approach was preferred 3 to 1 to the transgastric. Most participants preferred two-channel (2C) scopes (65 %) compared with single (1C) or three (3C) or more channels with p < 0.001 for both 2C versus 1C and 2C versus 3C. The importance of force feedback and the utility of a virtual NOTES simulator in training and testing new tools for NOTES were rated very high by the participants.

Conclusion

Our study reinforces the importance of developing a virtual NOTES simulator and clearly presents expert preferences. The results of this analysis will direct our initial development of the VTEST? platform.  相似文献

Background

Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemoperfusion (HIPEC) are frequently used to treat appendiceal carcinomatosis. Some patients require multivisceral resection because of the volume of disease. It is unclear whether extent of CRS impacts survival in appendiceal carcinomatosis.

Methods

We analyzed 282 patients undergoing attempted CRS/HIPEC for appendiceal carcinomatosis. Patients were defined as having undergone Extensive CRS (n = 60) if they had >3 organ resections or >2 anastomoses; a subgroup of Extreme CRS patients (n = 10) had ≥5 organ resections and ≥3 anastomoses. Kaplan–Meier survival curves and multivariate Cox-regression models were used to identify prognostic factors affecting outcomes.

Results

Relative to the comparison group, patients undergoing Extensive CRS had a higher median peritoneal carcinomatosis index, operative duration, blood loss, and length of stay. No difference in completeness of cytoreduction, severe morbidity, or 60-day mortality was evident. Subgroup analysis of 10 patients undergoing extreme CRS likewise revealed no increase in severe morbidity or mortality. Median progression-free (PFS) and overall survival (OS) were 23.5 and 74 months in the comparison group; 18.5 (p = 0.086) and 51 (p = 0.85) months in the Extensive CRS group; and 40 months and not reached in the Extreme CRS subgroup. In a multivariable analysis, extent of CRS was not independently associated with PFS or OS.

Conclusions

Extensive CRS is associated with greater OR time, blood loss, and length of stay, but is not associated with higher morbidity, mortality, or inferior oncologic outcomes in patients with appendiceal carcinomatosis.  相似文献

Introduction

Penile strangulation from constricting metallic objects disorders is an uncommon urological emergency which requires prompt intervention to prevent complications. The treatment modalities are diverse and characterized by lack of consensus.

Material and Methods

Three cases with penile incarceration due to constricting metallic objects who presented to our department were included in this study. All 3 patients required different management options highlighting the diversity of clinical presentation and need for customization of treatment as per the clinical scenario.

Results

The 3 patients required different approach for treatment. First patient could be managed by degloving of penile skin while second patient required mechanical removal of the foreign body and debridement of local necrotic tissues. The third patient had to undergo excision of gangrenous penile skin and skin grafting.

Conclusion

The study emphasizes the diversity of clinical presentations and the need for employing different surgical techniques to achieve the desired results.Key Words: Penile strangulation, Constricting objects, Penile amputation  相似文献

Abstract

Background/Objective: To determine whether 9 weeks of locomotor training (LT) results in changes in muscle strength and alterations in muscle size and activation after chronic incomplete spinal cord injury (SCI). Study Design: Longitudinal prospective case series.

Methods: Five individuals with chronic incomplete SCI completed 9 weeks of LT. Peak isometric torque, torque developed within the initial 200 milliseconds of contraction (Torque200), average rate of torque development (ARTD), and voluntary activation deficits were determined using isokinetic dynamometry for the knee-extensor (KE) and plantar-flexor (PF) muscle groups before and after LT. Maximum muscle crosssectional area (CSA) was measured prior to and after LT.

Results: Locomotor training resulted in improved peak torque production in all participants, with the largest increases in the more-involved PF (43.9% ± 20.0%), followed by the more-involved KE (21.1% ± 12.3%). Even larger improvements were realized in Torque200 and ARTD (indices of explosive torque), after LT. In particular, the largest improvements were realized in the Torque200 measures of the PF muscle group. Improvements in torque production were associated with enhanced voluntary activation in both the KE and ankle PF muscles and an increase in the maximal CSA of the ankle PF muscles.

Conclusion: Nine weeks of LT resulted in positive alterations in the KE and PF muscle groups that included an increase in muscle size, improved voluntary activation, and an improved ability to generate both peak and explosive torque about the knee and ankle joints.  相似文献

Objective

Extensive surgical subcutaneous emphysema (ESE) albeit a benign condition could cause patients distress and in many cases temporary vision impairment. We describe the role and value of early subcutaneous drain insertion (SCD) in the management of ESE and patients’ experience in this cohort study.

Methods

Extensive surgical subcutaneous emphysema is that which extends to the neck and/or the peri-orbital region. A cohort study of a prospectively collected data was conducted between December 2009 and January 2012. All patients with extensive post-operative surgical emphysema who had SCD (size ≥24 French gauge) were included.

Results

1069 thoracic procedures were performed. 21 patients (1.96 %) were diagnosed with extensive surgical emphysema, there were 16 males, median age was 65 (54–82 years). There were 16 VATS and 5 open procedures. All patients had chest surgical emphysema, 16 patients had peri-orbital and neck swelling and 5 had neck swelling. Surgical emphysema occurred within a median of 3 days post-operatively. 14 (67 %) patients had 1 subcutaneous drain inserted, and 7 (33 %) had bilateral SCD insertion (1 drain each side). 19 (90 %) patients experienced improvement of their symptoms with resolution of neck and peri-orbital swelling within 1 day of SCD insertion, 2 patients had their symptoms improved within 2 days. All patients were satisfied with the outcome following insertion of SCD.

Conclusions

ESE should always be investigated and treated promptly. Early SCD insertion has a valuable role in the management of ESE with improvement of patients’ experience.  相似文献
