Do the physical discomforts from breast cancer treatments affect the sexuality of women who underwent mastectomy?

The objective of this integrative review is to analyze the scientific production addressing the sexuality of women with breast cancer following mastectomy, focused on the effects that the physical discomfort due to cancer treatments have on their sex life. The search included articles published in the period between 2000 and 2009 on the MEDLINE, LILACS and PsycINFO databases, using the following descriptors: mastectomy, breast neoplasms, sexuality, sexual behavior, amputation, psychosexual development, and marital relations. Nine articles were selected, which addressed the effects of the physical discomfort from cancer treatments on the patients' sexuality. The findings revealed that, even when the patient's sex life is intense and fulfilling before the disease, factors such as stress, pain, fatigue, insult to body image, and low self-esteem due to the treatments may alter the sexual functioning of the affected woman. Healthcare professionals must be sensitized in order to welcome and include the topic in policies as well as in preventive, diagnostic, and therapeutic strategies.

FOLLOW-UP OF TREATED OSTEOSARCOMA PATIENT

Objective: To evaluate the value of post-treatment follow-up in osteosarcoma patients. Methods: Data were collected through a clinical record, with socio-demographic and clinical data, and information relating to the medical appointment. Descriptive analysis of the data was carried out. The Chi-squared test was used to associate the independent variables with attendance at scheduled follow-up appointments. Results: We found a recurrence in 59.6% of cases, of which 58% were lung related; 44% presented clinical complaints and arrived on the scheduled date of the appointment. There was no statistically significant association between the demographic characteristics and early attendance of follow-up visits. 81.3% of the cases who came for the appointment earlier than originally scheduled presented complaints compared to those who did not (p=0.005). Of the cases who presented recurrence, 12.9% attended an appointment late and those who did not present recurrence, 47.6% were late for the appointment (p=0.006). Conclusion: It is seen that the patients who came for an earlier appointment presented more complaints and were associated with the positive result of the exams carried out. The patients who had recurrence and came for an earlier appointment did not present a statistically significant difference in recurrence-free survival. It was observed that distance was not a predominant factor in late attendance at appointments. Level of Evidence II, Retrospective Study.

Effects of a combined strengthening, stretching and functional training program versus usual-care on gait biomechanics and foot function for diabetic neuropathy: a randomized controlled trial

Background: Polyneuropathy is a complication of diabetes mellitus that has been very challenging for clinicians. It results in high public health costs and has a huge impact on patients' quality of life. Preventive interventions are still the most important approach to avoid plantar ulceration and amputation, which is the most devastating endpoint of the disease. Some therapeutic interventions improve gait quality, confidence, and quality of life; however, there is no evidence yet of an effective physical therapy treatment for recovering musculoskeletal function and foot rollover during gait that could potentially redistribute plantar pressure and reduce the risk of ulcer formation. Methods/Design: A randomised, controlled trial, with blind assessment, was designed to study the effect of a physiotherapy intervention on foot rollover during gait, range of motion, muscle strength and function of the foot and ankle, and balance confidence. The main outcome is plantar pressure during foot rollover, and the secondary outcomes are kinetic and kinematic parameters of gait, neuropathy signs and symptoms, foot and ankle range of motion and function, muscle strength, and balance confidence. The intervention is carried out for 12 weeks, twice a week, for 40-60 min each session. The follow-up period is 24 weeks from the baseline condition. Discussion: Herein, we present a more comprehensive and specific physiotherapy approach for foot and ankle function, by choosing simple tasks, focusing on recovering range of motion, strength, and functionality of the joints most impaired by diabetic polyneuropathy. In addition, this intervention aims to transfer these peripheral gains to the functional and more complex task of foot rollover during gait, in order to reduce risk of ulceration. If it shows any benefit, this protocol can be used in clinical practice and can be indicated as complementary treatment for this disease.

Differential cellular FGF-2 upregulation in the rat facial nucleus following axotomy, functional electrical stimulation and corticosterone: a possible therapeutic target to Bell's palsy

Abstract Background The etiology of Bell's palsy can vary but anterograde axonal degeneration may delay spontaneous functional recovery leading the necessity of therapeutic interventions. Corticotherapy and/or complementary rehabilitation interventions have been employed. Thus the natural history of the disease reports to a neurotrophic resistance of adult facial motoneurons leading a favorable evolution however the related molecular mechanisms that might be therapeutically addressed in the resistant cases are not known. Fibroblast growth factor-2 (FGF-2) pathway signaling is a potential candidate for therapeutic development because its role on wound repair and autocrine/paracrine trophic mechanisms in the lesioned nervous system. Methods Adult rats received unilateral facial nerve crush, transection with amputation of nerve branches, or sham operation. Other group of unlesioned rats received a daily functional electrical stimulation in the levator labii superioris muscle (1 mA, 30 Hz, square wave) or systemic corticosterone (10 mgkg-1). Animals were sacrificed seven days later. Results Crush and transection lesions promoted no changes in the number of neurons but increased the neurofilament in the neuronal neuropil of axotomized facial nuclei. Axotomy also elevated the number of GFAP astrocytes (143% after crush; 277% after transection) and nuclear FGF-2 (57% after transection) in astrocytes (confirmed by two-color immunoperoxidase) in the ipsilateral facial nucleus. Image analysis reveled that a seven days functional electrical stimulation or corticosterone led to elevations of FGF-2 in the cytoplasm of neurons and in the nucleus of reactive astrocytes, respectively, without astrocytic reaction. Conclusion FGF-2 may exert paracrine/autocrine trophic actions in the facial nucleus and may be relevant as a therapeutic target to Bell's palsy.

Reimplantes nas amputações por mecanismo de avulsão: táticas e técnicas para o sucesso

OBJETIVOS: Avaliação retrospectiva criteriosa de casos de reimplantes após amputação por avulsão. Avaliação de técnicas e táticas utilizadas que determinaram evolução satisfatória e bom resultado funcional. METÓDOS: Foram avaliados, retrospectivamente, prontuários de 43 pacientes que tiveram membros amputados por mecanismo de avulsão e reimplantados nos últimos 21 anos. RESULTADOS: A maior parte dos casos envolvia homens adultos jovens. A localização de amputação mais frequente foi do polegar. As técnicas e táticas cirúrgicas utilizadas isoladas ou conjuntamente incluem: enxertos de nervo, enxertos vasculares (veia ou artéria), transposição de feixe vascular digital, encurtamento do membro e reimplante heterotópico. A técnica mais frequentemente utilizada foi o emprego de enxertos venosos. A taxa de sobrevida dos reimplantes foi alta (93%), assim como a satisfação dos pacientes. CONCLUSÃO: Os reimplantes por mecanismo de avulsão dependem do correto diagnóstico de viabilidade anatômica e utilização de técnicas e táticas cirúrgicas apropriadas para cada caso. A experiência da equipe cirúrgica e estrutura hospitalar adequada são fundamentais para obtenção de bons resultados. Existem poucos relatos na literatura sobre indicação, tática, técnicas e resultados de procedimentos de reimplantes em amputações por avulsão. Acreditamos que a avaliação retrospectiva desta série de casos possa trazer novas informações e contribuições no atendimento desta situação de alta complexidade.

Wertigkeit der Magnetresonanzangiographie der Fußgefäße unter Verwendung eines intravaskulären Kontrastmittels

In der vorliegenden Arbeit soll der Stellenwert der ce-MRA unter Verwendung von MS-325, einem neuen intravaskulären Kontrastmittel, bei der Untersuchung der Fußgefäße im Vergleich zur DSA bewertet, und das Übereinstimmen der Befunde zweier unterschiedlich erfahrener Untersucher untersucht werden. Im Rahmen einer klinischen Phase-III-Studie wurden 18 Patienten mit pAVK und / oder diabetischem Fußsyndrom rekrutiert. Die ce-MRA-Untersuchungen wurden in einem 1,5-Tesla-Magnetom durchgeführt. Dabei wurden dynamische Serien und eine hochaufgelöste Steady-state-Sequenz des zu untersuchenden Fußes akquiriert. Als Kontrastmittel wurde MS-325 in einer an das Körpergewicht adap-tierten Dosis appliziert. Die DSA-Untersuchung enthielt eine komplette Becken-Bein-Angiographie mit selektiver Darstellung der Fußgefäße. Vor der Befundung wurden die Bilddaten der MR-Angiographie nachbearbeitet und MIP-Projektionen erstellt. Zwei Untersucher befundeten unabhängig voneinander und in zufälliger Reinfolge die MRA, die DSA wurde in einem Konsensusverfahren beider Unter-sucher beurteilt. In eine qualitative Analyse gingen die Bewertung der Bildquali-tät, die Sichtbarkeit von sieben Gefäßsegmenten und deren hämodynamisch relevanter Stenosegrad ein. Quantitativ wurde das Signal-Rausch-Verhältnis und das Kontrast-Rausch-Verhältnis untersucht. Die Bildqualität beider Modalitäten wurde im Median mit gut bewertet. Hinsichtlich der Sichtbarkeit der Gefäßsegmente zeigte sich die ce-MRA der DSA überlegen. Von insgesamt 126 Gefäßsegmenten waren nur 80 in der DSA sichtbar, dagegen waren 106 Gefäßsegmente in der ce-MRA sichtbar (p-Wert <0,001, McNemar-Test). Die Übereinstimmung zwischen beiden Untersuchern der ce-MRA war sehr gut, beide erkannten 105 von 126 Gefäßsegmenten (Kappa-Maß κ=0,97). Beide Modalitäten werteten übereinstimmend 46 Gefäßsegmente als hämodynamisch relevant stenosiert. 16 Gefäßstenosen wurden durch die ce-MRA im Gegensatz zur DSA überbewertet. Zwischen Untersucher 1 und Untersucher 2 der ce-MRA fand sich erneut eine sehr gute Übereinstimmung (Kappa-Maß к = 0,89). Die Messungen des SNR und des CNR ergaben sowohl in den dynamischen Se-quenzen als auch in der später akquirierten hochaufgelösten Steady-state Unter-suchung hohe Werte. Die Bildqualität der hochaufgelösten Steady-state ce-MRA war hervorragend, jedoch beeinträchtigt venöse Überlagerung die Interpretation. In der Literatur wird die ce-MRA als ein geeignetes Verfahren zur Darstellung von Fußgefäßen beschrieben. Zahlreiche Studien zeigen, dass mit der ce-MRA mehr Gefäßsegmente dargestellt werden können. Dieses Ergebnis konnte in der vor-liegenden Arbeit bestätigt werden. Eine mit MS-325 verstärkte Magnetresonanz-angiographie der Fußgefäße ist der selektiven DSA überlegen. Die Tatsache, dass mit der ce-MRA mehr Gefäßsegmente dargestellt werden können, hat den Begriff des angiographisch „verborgenen“ Blutgefäßes initiiert. In vielen klini-schen Zentren hat die ce-MRA die DSA weitgehend verdrängt. Aus diesem Grund wird in der Literatur vorgeschlagen, dass die ce-MRA die DSA als einen „verbes-serten Goldstandard“ ersetzten könnte. Kann mit der DSA kein passendes An-schlussgefäß für eine Revaskularisationsmaßnahme mittels Bypass gefunden werden, so sollte auf jeden Fall eine ce-MRA der Fußgefäße durchgeführt wer-den, um eine Amputation zu verhindern. In der Literatur wird von der Änderung der Behandlungsstrategie nach der Durchführung der ce-MRA berichtet. Bei der Klassifikation von Gefäßstenosen wertet die ce-MRA öfter höher als die DSA, diese Überbewertung ist in der Literatur bekannt und konnte ebenfalls in der vorliegenden Arbeit bestätigt werden. Diese Überschätzung resultiert aus „Spin-Dephasierung“ durch turbulente Blutströmung im Bereich einer Stenose oder besteht auf Grund von Partialvolumeneffekten. Die Verwendung eines intravaskulären Kontrastmittels, wie bsw. MS-325, zur MR-Angiographie bringt den Vorteil, dass sowohl dynamische als auch Steady-state Untersuchungen aller vaskulären Strukturen im menschlichen Körper durchge-führt werden können. Da eine hohe Signalintensität über einen langen Zeitraum besteht, können auch mehrere Körperregionen während einer einzigen Untersu-chung dargestellt werden. Nachteilig ist jedoch die Beeinträchtigung der Bildge-bung durch venöse Überlagerung. Mittels computergestützter Bildnachbearbeitung ist es jedoch möglich, Venen in Steady-state-Sequenzen zu unterdrücken und daraus ergibt sich die Möglichkeit, hochaufgelöste, überlage-rungsfreie Datensätze zu erhalten. Diese könnten dann der erste Schritt in Rich-tung einer Perfusionsbildgebung am Fuß sein, um bsw. den Erfolg von Revaskularisationsmaßnahmen auch auf Kapillarebene beurteilen zu können.

Reconstructive Microsurgery and Tissue Engineering in Musculo-Skeletal Oncology - Innovative Techniques

Tumors involving bone and soft tissues are extremely challenging situations. With the recent advances of multi-modal treatment, not only the type of surgery has moved from amputation to limb-sparing procedures, but also the survivorship has improved considerably and reconstructive techniques have the goal to allow a considerably higher quality of life. In bone reconstruction, tissue engineering strategies are the main area of research. Re-vascularization and re-vitalisation of a massive allograft would considerably improve the outcome of biological reconstructions. Using a rabbit animal model, in this study we showed that, by implanting a vascular pedicle inside a weight bearing massive cortical allograft, the bone regeneration inside the allograft was higher compared to the non-vascularized implants, given the patency of the vascular pedicle. Improvement in the animal model and the addition of Stem Cells and Growth factors will allow a further improvement in the results. In soft tissue tumors, free and pedicled flaps have been proven to be of great help as reconstruction strategies. In this study we analyzed the functional and overall outcome of 14 patients who received a re-innervated vascularized flap. We have demonstrated that the use of the innovative technique of motor re-innervated muscular flaps is effective when the resection involves important functional compartments of the upper or lower limb, with no increase of post-operative complications. Although there was no direct comparison between this type of reconstruction and the standard non-innervated reconstruction, we underlined the remarkable high overall functional scores and patient satisfaction following this procedure.

Plasticity in body and peripersonal space representations

A successful interaction with objects in the environment requires integrating information concerning object-location with the shape, dimension and position of body parts in space. The former information is coded in a multisensory representation of the space around the body, i.e. peripersonal space (PPS), whereas the latter is enabled by an online, constantly updated, action-orientated multisensory representation of the body (BR) that is critical for action. One of the critical features of these representations is that both PPS and BR are not fixed, but they dynamically change depending on different types of experience. In a series of experiment, I studied plastic properties of PPS and BR in humans. I have developed a series of methods to measure the boundaries of PPS representation (Chapter 4), to study its neural correlates (Chapter 3) and to assess BRs. These tasks have been used to study changes in PPS and BR following tool-use (Chapter 5), multisensory stimulation (Chapter 6), amputation and prosthesis implantation (Chapter 7) or social interaction (Chapter 8). I found that changes in the function (tool-use) and the structure (amputation and prosthesis implantation) of the physical body elongate or shrink both PPS and BR. Social context and social interaction also shape PPS representation. Such high degree of plasticity suggests that our sense of body in space is not given at once, but it is constantly constructed and adapted through experience.

Preservation of Amputated Extremities by Extracorporeal Blood Perfusion; a Feasibility Study in a Porcine Model

Successful extremity transplantations and replantations have to be performed within 6 h of amputation to avoid irreversible tissue loss. This study investigates ex vivo the technical feasibility and the limb preservation potential of extracorporeal whole blood perfusion in a porcine model.

A case of Maffucci syndrome

The Maffucci syndrome consists of a combination of multiple enchondromas and haemangiomas. It appears in the first two decades of life, with no family history. In this case we are reporting about a 26-year-old female who had suffered from multiple enchondromas since the age of two. At the age of nine, the patient presented with additional haemangiomas, which facilitated making proper diagnosis. She now presents with a massive lesion of her left upper extremity. The patient had initially rejected operative treatment when the disease was at early stages. At later stages, a more complex reconstruction of the hand would have been necessary to secure hand function. This procedure that sometimes induces a risk related to potential necessity of blood transfusion was rejected by the patient for religious reasons. Amputation of the extremity was therefore the last resort procedure.

Results of the randomized, placebo-controlled clopidogrel and acetylsalicylic acid in bypass surgery for peripheral arterial disease (CASPAR) trial

OBJECTIVE: Dual antiplatelet therapy with clopidogrel plus acetylsalicylic acid (ASA) is superior to ASA alone in patients with acute coronary syndromes and in those undergoing percutaneous coronary intervention. We sought to determine whether clopidogrel plus ASA conferred benefit on limb outcomes over ASA alone in patients undergoing below-knee bypass grafting. METHODS: Patients undergoing unilateral, below-knee bypass graft for atherosclerotic peripheral arterial disease (PAD) were enrolled 2 to 4 days after surgery and were randomly assigned to clopidogrel 75 mg/day plus ASA 75 to 100 mg/day or placebo plus ASA 75 to 100 mg/day for 6 to 24 months. The primary efficacy endpoint was a composite of index-graft occlusion or revascularization, above-ankle amputation of the affected limb, or death. The primary safety endpoint was severe bleeding (Global Utilization of Streptokinase and Tissue plasminogen activator for Occluded coronary arteries [GUSTO] classification). RESULTS: In the overall population, the primary endpoint occurred in 149 of 425 patients in the clopidogrel group vs 151 of 426 patients in the placebo (plus ASA) group (hazard ratio [HR], 0.98; 95% confidence interval [CI], 0.78-1.23). In a prespecified subgroup analysis, the primary endpoint was significantly reduced by clopidogrel in prosthetic graft patients (HR, 0.65; 95% CI, 0.45-0.95; P = .025) but not in venous graft patients (HR, 1.25; 95% CI, 0.94-1.67, not significant [NS]). A significant statistical interaction between treatment effect and graft type was observed (P(interaction) = .008). Although total bleeds were more frequent with clopidogrel, there was no significant difference between the rates of severe bleeding in the clopidogrel and placebo (plus ASA) groups (2.1% vs 1.2%). CONCLUSION: The combination of clopidogrel plus ASA did not improve limb or systemic outcomes in the overall population of PAD patients requiring below-knee bypass grafting. Subgroup analysis suggests that clopidogrel plus ASA confers benefit in patients receiving prosthetic grafts without significantly increasing major bleeding risk.

Vascular hospitalization rates and costs in patients with peripheral artery disease in the United States

BACKGROUND: Peripheral artery disease (PAD) is common and imposes a high risk of major systemic and limb ischemic events. The REduction of Atherothrombosis for Continued Health (REACH) Registry is an international prospective registry of patients at risk of atherothrombosis caused by established arterial disease or the presence of 3 atherothrombotic risk factors. METHODS AND RESULTS: We compared the 2-year rates of vascular-related hospitalizations and associated costs in US patients with established PAD across patient subgroups. Symptomatic PAD at enrollment was identified on the basis of current intermittent claudication with an ankle-brachial index (ABI) <0.90 or a history of lower-limb revascularization or amputation. Asymptomatic PAD was diagnosed on the basis of an enrollment ABI <0.90 in the absence of symptoms. Overall, 25 763 of the total 68 236-patient REACH cohort were enrolled from US sites; 2396 (9.3%) had symptomatic and 213 (0.8%) had asymptomatic PAD at baseline. One- and cumulative 2-year follow-up data were available for 2137 (82%) and 1677 (64%) of US REACH patients with either symptomatic or asymptomatic PAD, respectively. At 2 years, mean cumulative hospitalization costs, per patient, were $7445, $7000, $10 430, and $11 693 for patients with asymptomatic PAD, a history of claudication, lower-limb amputation, and revascularization, respectively (P=0.007). A history of peripheral intervention (lower-limb revascularization or amputation) was associated with higher rates of subsequent procedures at both 1 and 2 years. CONCLUSIONS: The economic burden of PAD is high. Recurring hospitalizations and repeat revascularization procedures suggest that neither patients, physicians, nor healthcare systems should assume that a first admission for a lower-extremity PAD procedure serves as a permanent resolution of this costly and debilitating condition.

One hundred fascia-sparing myocutaneous rectus abdominis flaps: An update

Major efforts have been undertaken to reduce donor-site morbidity after abdominal flaps, which eventually culminated in the introduction of the deep inferior epigastric perforator (DIEP) flap. However, due to anatomical variations (absence of dominant perforators) and the risk of ischaemic complications, the selection of patients qualifying for a DIEP flap is limited. Furthermore, DIEP flaps can only be used as free flaps. We present our long-term experience with a dissection technique of rectus abdominis myocutaneous (RAM) flaps that was developed to circumvent these drawbacks. The dissection is characterised by preventing to sacrifice any perforators nourishing the flap and by fully preserving the anterior rectus sheath, but not the muscle. The study comprises a consecutive series of prospectively assessed patients, treated between February 2000 and April 2008. A total of 100 fascia-sparing RAM flaps were operated on 97 patients (age 22-84 years, median 64 years). Free flaps were mainly used for breast reconstruction (47 flaps/24 patients), and cranially (34) or caudally (19) pedicled flaps for soft-tissue coverage after sternectomy, urogenital tumour resection or rectum amputation. Eighty patients had a total of 213 risk factors, such as cardiovascular diseases, obesity, hyperlipidaemia, diabetes mellitus, smoking or steroid medication. Partial tissue loss (skin or fat necrosis) occurred in 13 flaps, out of which seven required surgical revision. The ischaemic complications were evenly distributed between the patient subsets. At a follow-up of 2-89 months (median 20 months), one patient showed a flap harvest-related abdominal bulge after bilateral-free transverse rectus abdominis myocutaneous (TRAM) flap. We conclude that the present dissection technique provides maximal perforator-related perfusion and minimal donor-site morbidity even in pedicled flaps and high-risk patients. In free flaps, it may, therefore, be recommended as an alternative to the DIEP flap.

Insights on the role of diabetes and geographic variation in patients with critical limb ischaemia

Patients with critical limb ischaemia (CLI) unsuitable for revascularisation have a high rate of amputation and mortality (30% and 25% at 1 year, respectively). Localised gene therapy using plasmid DNA encoding acidic fibroblast growth factor (NV1FGF, riferminogene pecaplasmid) has showed an increased amputation-free survival in a phase II trial. This article provides the rationale, design and baseline characteristics of CLI patients enrolled in the pivotal phase III trial (EFC6145/TAMARIS).
