The amputees and quality of life

The application of highly sophisticated computer technology and high technology materials allows production of quality prosthetic replacements both in the functional and esthetic sense. The basic prerequisite for successful use of prostheses is an adequately shaped stump, which can be achieved using new operative technique used for extremity amputation. In this way, the possibilities of prosthetic device usage are enlarged to fulfill not only basic daily needs but also highly active work-related, sports-related or recreational needs of the modern man. However, the adequate and successfully performed operative procedure and the implementation of a quality prosthetic device do not guarantee that all patient requirements for improved quality of life are fulfilled. The aim of this study was to examine therapeutic effects of the applied method of surgical and prosthetic treatment, with a special focus on the improvement of patient's quality of life. The research was conducted in a sample of healthy and active patients with trauma-related lower extremity amputation. Following a positive objective evaluation by the physician, who stated that surgical and prosthetic treatment was satisfactory, the subjective evaluation was performed by the patient using a specially designed questionnaire. The factors possibly influencing the overall satisfaction of the patient with therapy were analyzed. The satisfaction with prosthesis function was evaluated as very good by 63.5% of the patients, excellent by 9.6% and good by 26.9% of the patients.     

The satisfaction with the removable partial denture therapy in the Croatian adult population

Little is known about the outcomes of treatment and patient's satisfaction with removable partial dentures in adult Croatian population. Therefore patient's satisfaction with their partial dentures in relation to some socio-economic variables was studied. Patient's satisfaction with denture retention, speech, aesthetics, comfort of wearing dentures, chewing ability was also studied in relation to different denture classification, construction, material, denture base shape (major connectors), denture support and the number of missing teeth. A total of 165 patients, 59 males and 105 females between 38 and 87 years took part in this study. A questionnaire, devised for a purpose of the study, was divided into three parts. In the first part, patients answered questions about age, gender, marital status, education, general health, socio-economic status, self-supporting life, period of tooth loss and number of previous denture experiences and in the second part, patients graded their partial dentures, depending on the level of satisfaction, by using a scale from 1 to 5. In the third part a dentist determined Kennedy classification and their modifications, denture material and denture support, denture base shape and the number of missing teeth and graded a denture construction. Influence of these factors on patient's satisfaction was analyzed. A majority of the examined patients were satisfied with the partial prosthesis, but a small amount of dissatisfaction existed. More then half of them scored all the examined parameters to the best score category. Considering chewing with lower partial dentures, women were more satisfied than men (p < 0.05). Patients with more missing teeth gave lower grades for the comfort of wearing dentures (p < 0.05). Patients of higher education gave lower grades (p < 0.05) for the aesthetics. Patients were not satisfied with speech if the dentist graded a construction of a lower partial denture low (p < 0.05). Dissatisfaction was related to mastication, aesthetics, number of missing teeth and ability of speech. These findings can aid a clinician in discussing a treatment plan and help a patient understand the risk of dissatisfaction in the presence of certain factors.     

Kinetics of individual limbs during level and slope walking with a unilateral transtibial bone-anchored prosthesis in the cat

Ongoing animal preclinical studies on transcutaneous bone-anchored prostheses have aimed to improve biomechanics of prosthetic locomotion in people with limb loss. It is much less common to translate successful developments in human biomechanics and prosthetic research to veterinary medicine to treat animals with limb loss. Current standard of care in veterinary medicine is amputation of the whole limb if a distal segment cannot be salvaged. Bone-anchored transcutaneous prostheses, developed for people with limb loss, could be beneficial for veterinary practice. The aim of this study was to examined if and how cats utilize the limb with a bone-anchored passive transtibial prosthesis during level and slope walking. Four cats were implanted with a porous titanium implant into the right distal tibia. Ground reaction forces and full-body kinematics were recorded during level and slope (±50%) walking before and 4–6 months after implantation and prosthesis attachment. The duty factor of the prosthetic limb exceeded zero in all cats and slope conditions (p < 0.05) and was in the range of 45.0–60.6%. Thus, cats utilized the prosthetic leg for locomotion instead of walking on three legs. Ground reaction forces, power and work of the prosthetic limb were reduced compared to intact locomotion, whereas those of the contralateral hind- and forelimbs increased (p < 0.05). This asymmetry was likely caused by insufficient energy generation for propulsion by the prosthetic leg, as no signs of pain or discomfort were observed in the animals. We concluded that cats could utilize a unilateral bone-anchored transtibial prosthesis for quadrupedal level and slope locomotion.     

Clinical determinants of patient satisfaction with breast reconstruction

The main objective of this study was to examine the relationship between specific treatment variables and patient satisfaction with breast reconstruction. A questionnaire was developed that included questions on population demographics and satisfaction with the reconstruction. Of 206 women who completed the questionnaire, 23 (11.2 percent) responded that they were not satisfied, whereas 183 (88.8 percent) indicated that they were satisfied overall. A detailed retrospective chart review permitted a comparison of the treatment received by these two groups. Variables analyzed included patient age, time since surgery, reason for surgery, method and timing of reconstruction, additional surgical procedures received (mound revisions and nipple-areola complex reconstruction), and postoperative complications. Data analysis showed that the treatment received by the two groups was similar in many respects. There was no statistical association between the method or timing of reconstruction and a patient's satisfaction with the results. Furthermore, there was no difference in the number of mound revisions or nipple reconstructions performed on satisfied versus dissatisfied patients. However, the latter group experienced a substantially higher incidence of postsurgical complications (27 percent versus 61 percent, p = 0.0015). Patients were also asked to provide a written response explaining their feelings on breast reconstruction. Satisfied patients described benefits from reconstruction such as improved appearance or feelings of normalcy and wholeness. Conversely, unsatisfied patients were displeased because of poor cosmetic results, complications with the reconstructed breast, or abdominal problems. Although overall satisfaction with breast reconstruction is undoubtedly determined by multiple and complex clinical, emotional, and psychological factors, this study suggests that postoperative complications are a particularly important indicator of dissatisfaction with reconstruction.     

Thrombosis of Bj?rk-Shiley aortic valve prosthesis: report of three cases.

Thrombotic malfunction of a Björk-Shiley aortic valve prosthesis occurred in three patients 6 to 16 months postoperatively. None of the patients had been taking anticoagulants. Although the presentation was acute, prodromal symptoms could be identified retrospectively in two of the patients. Two patients survived thrombectomy. Postoperative anticoagulant therapy is recommended in patients with these prostheses despite factors that may make such therapy riskier in specific patients. Attention to the character of murmurs and of the closure sound of the prosthetic valve must be part of the routine follow-up. In the emergency situation, when delay must be avoided, catheterization and angiography are unnecessary. The operative approach consists of complete thrombectomy without replacement of the valve or any of its components unless there is obvious periprosthetic leak or prosthetic wear.

Replantation versus Prosthetic Fitting in Traumatic Arm Amputations: A Systematic Review

Background

Traumatic arm amputations can be treated with replantation or surgical formalization of the stump with or without subsequent prosthetic fitting. In the literature, many authors suggest the superiority of replantation. This systematic review compared available literature to analyze whether replantation is functionally and psychologically more profitable than formalization and prosthetic fitting in patients with traumatic arm amputation.

Methods

Functional outcome and satisfaction levels were recorded of patients with amputation levels below elbow, through elbow, and above elbow.

Results

Functional outcomes of 301 replantation patients and 172 prosthesis patients were obtained. In the replantation group, good or excellent functional scores were reported in 39% of above elbow, 55% of through elbow, and 50% of below elbow amputation cases. Nearly 100% of patients were satisfied with the replanted limb. In the prosthesis group, full use of the prosthesis was attained in 48% of above elbow and in 89% of below elbow amputation patients. Here, 29% of patients elected not to use the prosthesis for reasons including pain and functional superfluity. In both replantation patients and prosthesis wearers, a below elbow amputation yielded better functional results than higher amputation levels.

Conclusions

Replantation of a traumatically amputated arm leads to good function and higher satisfaction rates than a prosthesis, regardless of the objective functional outcome. Sensation and psychological well-being seem the two major advantages of replantation over a prosthesis. The current review of the available literature shows that in carefully selected cases replantation could be the preferred option of treatment.     

Breast reconstruction using modified tissue expansion

Inadequate chest-wall skin following mastectomy for carcinoma continues to be a problem in many breast reconstructions. To avoid extensive surgery, serial tissue expansion has been advocated. Since 1977, one of the authors has used a simple method of tissue expansion that we have termed "modified tissue expansion", defined as the creation of an adequate breast mound in one or two stages using a permanent prosthesis. Ninety percent of patients undergoing breast reconstruction between 1978 and 1983 were reconstructed using this method. A retrospective analysis of these 208 patients is presented. There were no mortalities, and only a 6.3 percent complication rate. Skin necroses related directly to the prosthesis occurred once, and there were no prosthetic deflations. Eighteen percent had first-step reconstruction only. The initial prosthesis averaged 400 cc in size. Selected Halsted radical mastectomy and postradiotherapy patients were successfully reconstructed. Seventy-eight percent felt their results were excellent at 1 year. Two percent were dissatisfied. Multiple office visits and the potential problems of serial expansion were avoided. Modified tissue expansion is a simple and viable method and should be considered among the options for breast reconstruction following mastectomy.     

Loosening of cementless femoral stems: a biomechanical analysis of immediate fixation with loading vertical, femur horizontal

Large joint implants must have immediate fixation to be successful. Unfortunately, the magnitude and consistency of achieving this remains largely unknown. For cementless femoral components it is being increasingly appreciated that torsional loading as occurs during stair climbing or rising from a chair leads to loosening and thigh pain in some cases. A biomechanical test was developed to evaluate fixation in this position. Twelve pairs of human cadaveric femora were press-fit with an AML stem. Each femur was secured in a horizontal position, and the prosthetic head cyclically loaded in a vertically downward direction. The offset of the prosthetic head resulted in a combined torsional and compressive load being applied to the stem within the proximal femur. Loosening was found to consistently occur and rapidly accelerate when the head subsided more than 0.2 mm during 100 cycles. For the AML stem, loosening developed at loads from 62 to 171% of body weight and after as few as 800 cycles. This is within the physiologic range of normal daily activities as measured by others with instrumented prostheses. This poses a challenge to the ability of press-fit stems to tolerate torsional loads in vivo. Patients with a cementless prosthesis should be protected from torsional loading until porous ingrowth and/or bone remodelling have had time to occur. Testing the same stem in paired femora demonstrated no right vs left difference (p greater than 0.6).     

Implant prosthetic rehabilitation of the patients with mandibular resection following oral malignoma surgery

Patient underwent mandibular resection due to surgical therapy of oropharingeal malignoma. Facial asymmetry and cosmetic distortion are frequent consequences of such interventions, which may also include deviation and intrusion of the mandible, motor and sensory disorders, abnormal intermaxillary relations and malocclusion. Implant-supported prosthesis could be an optimal solution to prosthodontic treatment of such patients. However, there is a problem in determination of stable (interocclusal) intermaxillary relations. This article describes the choice of therapy and procedures undertaken in prosthetic rehabilitation of a patient who underwent mandibular resection and radiotherapy with supported prosthesis retained with four implants.     

Influences on control in diabetes mellitus: patient,doctor, practice,or delivery of care?

OBJECTIVE--To assess patient, doctor, practice, and process of care variables for their effect on glycaemic control in diabetes mellitus, and to quantify their relative effects. DESIGN--Search of general practice medical records, patient questionnaires and examination, doctor questionnaire, videotaping and analysis of consultations, and practice questionnaire. SETTING--12 practices with 32 participating general practitioners in Nottinghamshire. SUBJECTS--318 patients randomly selected from those with diabetes in each practice, 10 for each participating doctor. MAIN OUTCOME MEASURE--Glycaemic control as measured by random glycated haemoglobin A1c estimation (random haemoglobin A1 measurement). RESULTS--Glycaemic control was significantly related to the disease process as measured by years since diagnosis, treatment group, and number of diabetes related clinical events. Females had significantly worse control than males. Other patient factors, such as age, social class, lifestyle, attitudes, satisfaction, and knowledge, had no association with glycaemic control. Of all the doctor factors examined, only doctors who professed a special interest in diabetes achieved significantly better glycaemic control. Bigger and better equipped practices and those with a diabetic miniclinic had patients with significantly better glycaemic control, as did those with access to dietetic advice. Patients attending hospital clinics had worse glycaemic control, but this seemed to be attributable to the case mix and practice characteristics. Shared care did not contribute to the multiple linear regression model. CONCLUSION--Glycaemic control among diabetic patients in the community is related to such factors as treatment group, sex, and years since diagnosis; it is also related to the organisation and process of care. The findings support concentrating diabetic care on partners with special interests in diabetes in well equipped practices with adequate dietetic support.     

Immune response to CagA protein is associated with improved platelet count after Helicobacter pylori eradication in patients with idiopathic thrombocytopenic purpura

BACKGROUND: Improvement in platelet counts has been reported after eradication of Helicobacter pylori in patients with idiopathic thrombocytopenic purpura (ITP). We examined the levels of serum markers of gastritis and anti-CagA (cytotoxin-associated gene A) IgG antibody in patients with ITP to investigate whether these factors are associated with the platelet response after H. pylori eradication therapy. MATERIALS AND METHODS: One hundred and sixteen consecutive patients with ITP were assessed for H. pylori infection by (13)C-urea breath test and serum H. pylori antibody test. Patients with H. pylori infection received eradication therapy. Before and after eradication therapy, we evaluated serum levels of gastrin, pepsinogen (PG)-I, and PG-II and the anti-CagA IgG antibody titer. RESULTS: H. pylori infection was found in 67 (58%) of the 116 patients with ITP. Fifty-two infected patients received eradication therapy, which was successful in 44 patients (85%). Twenty-seven patients (62%) showed an increased platelet count and were identified as responders. The duration of ITP was shorter in responders than in nonresponders (p = .017). There was no difference of the levels of gastrin and PGs between responders and nonresponders. Before eradication therapy, the serum anti-CagA antibody titer did not differ significantly between responders and nonresponders. However, reduction in the anti-CagA antibody titer after eradication therapy was significantly greater in responders than in nonresponders (p = .013). CONCLUSIONS: H. pylori eradication therapy improves the platelet count in H. pylori-positive patients with ITP of short duration. Immune response of hosts to CagA protein of H. pylori may play a role in the pathogenesis of ITP.     

Nipple-areola reconstruction: satisfaction and clinical determinants

After performing a chart review, the authors identified 120 patients who underwent breast cancer-related reconstruction. All charts were evaluated with regard to breast mound reconstruction type, nipple-areola reconstruction type, the interval between breast mound and nipple-areola reconstruction, the number of procedures needed to achieve nipple-areola reconstruction, patient history of radiation therapy, and complications. A questionnaire was then developed and mailed to all of the patients who underwent both breast mound and nipple/areola reconstruction (n = 105) to evaluate their level of satisfaction. Of the 43 patients who returned the questionnaire, 41 completed all portions correctly. The questionnaire evaluated patient satisfaction with breast mound reconstruction; patient satisfaction with nipple-areola reconstruction; what the patient disliked most about the nipple-areola reconstruction; and whether or not the patient would choose to have breast reconstruction again. Several parameters were then tested statistically against the reported patient satisfaction.A review of all patients who underwent breast reconstruction revealed that their breast mound reconstructions were done using either a TRAM flap (59 percent), a latissimus dorsi flap and an implant (19 percent), an expander followed by an implant (9 percent), an implant only (4 percent), or other means (9 percent). The nipple-areola was reconstructed in these patients with either a star flap (36 percent), nipple sharing (10 percent), a keyhole flap (9 percent), a skate flap (9 percent), an S-flap (8 percent), a full-thickness skin graft (6 percent), or by another means (22 percent). The number of procedures needed to achieve nipple-areola reconstruction was either one (in 66 percent of the patients), two (in 32 percent of the patients), or three or more (2 percent of the patients). Eleven percent of the patients experienced the complication of nipple necrosis.Satisfaction with breast mound reconstruction was reported by 81 percent of patients to be excellent/good, by 14 percent of patients to be fair, and by 5 percent of patients to be poor. Reported satisfaction with nipple-areola reconstruction was excellent/good for 64 percent of patients, fair for 22 percent of patients, and poor for 14 percent of patients. The factors patients disliked most about their nipple-areola reconstruction were, in descending order, lack of projection, color match, shape, size, texture, and position. Statistical analysis of the data revealed inferior patient satisfaction when there was a longer interval between breast mound and nipple areola reconstruction (p = 0.003). No significant difference was observed in nipple/areola reconstruction satisfaction ratings when compared with breast mound reconstruction type (p = 0.46), nipple-areola reconstruction type (p = 0.98), and history of radiation therapy (p = 0.23). There was also no significant difference when breast mound reconstruction was compared with technique (p = 0.51) and history of radiation therapy (p = 0.079). Overall, there was a greater satisfaction with breast mound reconstruction than with nipple-areola reconstruction (p = 0.0001).

Variables affecting denture satisfaction in Israeli elderly:a one year follow-up

The purpose of this study was to investigate patient satisfaction with complete dentures after one year of use and several potential mitigating factors in Israeli elderly. Eighty–four patients who were 54 years of age or older and who were rehabilitated with complete dentures were recalled for examination 12-15 months later; 84.5% (n=70) were interviewed and reexamined by calibrated examiners who judged all prostheses to be clinically acceptable. The mean age of participants was 71.90 years and two-thirds were females. Over 73 % reported that they wore their dentures “always.” Nearly 79% indicated that they were pleased with their denture appearance. Difficulties were reported by 28.2%, while 46.5% reported difficulties with chewing. Chewing problems were significantly related to swallowing problems (P<.001); food enjoyment “as much now as you did five years ago” (P<.001); difficulties speaking (P<.00105) and “having sores under your dentures” (P<.00101) which affected 28.2% of the survey group. Married elderly expressed higher satisfaction with denture comfort as compared to “single” patients, and patients suffering from any systemic chronic diseases were more dissatisfied with appearance. A summary satisfaction scale of 7 items was constructed (Cronbach alpha reliability 0.6834) and logistic regression performed to identify key model variables for overall satisfaction. Stat sign findings included: 1) immigration year; 2) neurological or psychological disorder; and 3) age. The model correctly classified 92.75%. Findings suggest that a variety of factors may influence denture satisfaction. Gathering detailed information by means of a questionnaire before new denture fabrication may be an important tool for the dentist in predicting and consequently enhancing patient satisfaction with complete dentures.     

Biomechanics of the ankle-foot system during stair ambulation: implications for design of advanced ankle-foot prostheses

Unilateral lower limb prosthesis users display temporal, kinematic, and kinetic asymmetries between limbs while ascending and descending stairs. These asymmetries are due, in part, to the inability of current prosthetic devices to effectively mimic normal ankle function. The purpose of this study was to provide a comprehensive set of biomechanical data for able-bodied and unilateral transtibial amputee (TTA) ankle-foot systems for level-ground (LG), stair ascent (SA), and stair descent (SD), and to characterize deviations from normal performance associated with prosthesis use. Ankle joint kinematics, kinetics, torque-angle curves, and effective shapes were calculated for twelve able-bodied individuals and twelve individuals with TTA. The data from this study demonstrated the prosthetic limb can more effectively mimic the range of motion and power output of a normal ankle-foot during LG compared to SA and SD. There were larger differences between the prosthetic and able-bodied limbs during SA and SD, most evident in the torque-angle curves and effective shapes. These data can be used by persons designing ankle-foot prostheses and provide comparative data for assessment of future ankle-foot prosthesis designs.     

The infected or exposed breast implant: management and treatment strategies

Among the potential complications associated with the use of breast implants are the risks of periprosthetic infection and device extrusion. There is little published information about the effective management of these situations. Conservative recommendations include antibiotic therapy and removal of the implant until resolution of the infection or until the wound has healed. A retrospective review identified patients with periprosthetic infection or threatened or actual device exposure treated by the senior author. Twenty-four patients encompassing 26 affected prostheses were available for review and were classified into seven groups based on initial presentation as follows: group 1, mild infection (n = 8); group 2, severe infection (n = 4); group 3, threatened exposure without infection (n = 3); group 4, threatened exposure with mild infection (n = 3); group 5, threatened exposure with severe infection (n = 1); group 6, actual exposure without clinical infection (n = 5); and group 7, actual exposure with infection (n = 2). To salvage the prosthesis in these patients, various treatment strategies were utilized. All patients with a suspected infection or device exposure were started immediately on appropriate antibiotic therapy (oral antibiotics for mild infections and parenteral antibiotics for severe infections). Salvage methods included one or more of the following: antibiotic therapy, débridement, curettage, pulse lavage, capsulectomy, device exchange, primary closure, and/or flap coverage. Twenty (76.9 percent) of 26 threatened implants with infection or threatened or actual prosthesis exposure were salvaged after aggressive intervention. The presence of severe infection adversely affected the salvage rate in this series. A statistically significant difference exists among those patients without infection or with mild infection only (groups 1, 3, 4, and 6); successful salvage was achieved in 18 (94.7 percent) of 19 patients, whereas only two of seven of those implants with severe infection (groups 2, 5, and 7) were salvaged (p = 0.0017). Ten (90.9 percent) of 11 devices with threatened or actual exposure, not complicated by severe infection (groups 3, 4, and 6), were salvaged. Several treatment strategies were developed for periprosthetic infection and for threatened or actual implant exposure. Patients with infection were placed on oral or intravenous antibiotics; those who responded completely required no further treatment. For persistent mild infection or threatened or actual exposure, operative intervention was required, including some or all of the following steps: implant removal, pocket curettage, partial or total capsulectomy, débridement, site change, placement of a new implant, and/or flap coverage; the menu of options varied with the precise circumstances. No immediate salvage was attempted in five cases, due to either severe infection, nonresponding infection with gross purulence, marginal tissues, or lack of options for healthy tissue coverage. Based on the authors' experience, salvage attempts for periprosthetic infection and prosthesis exposure may be successful, except in cases of overwhelming infection or deficient soft-tissue coverage. Although an attempt at implant salvage may be offered to a patient, device removal and delayed reinsertion will always remain a more conservative and predictable option.
