Treatment of Bilateral Recurrent Dislocation of Hip Pros-thesis with Malpositioned Well-Fixed Shell: A Case Report  [PDF]
Fernando Judas, Luis Maximino, Francisco Lucas
Open Journal of Orthopedics (OJO) , 2013, DOI: 10.4236/ojo.2013.33031
Abstract: Dislocations of total hip prostheses cause pain and patient dissatisfaction. Recurrent dislocations are difficult to treat mainly when the acetabular metal shell is well-fixed. The purpose of this article was to describe the surgical technique used for the treatment of a bilateral recurrent posterior dislocation after a cementless total hip prosthesis, caused by excessive inclination of acetabular components, in a 72-year-old patient. On both sides, acetabular metal shell, porouscoated, was well-fixed. Revision of the entire acetabular component could be an appropriate therapeutic option because it was malpositioned. Nevertheless, a conservative operation was performed. The metal shell was left in situ and the preexisting polyethylene liner was removed and replaced by a new undersized cross-linked polyethylene liner, then, cemented into the shell and properly oriented. An acetabular cemented augmentation reinforced by 3 cortical screws was associated with the reconstruction. This report suggests that cementation of new liner into a malpositioned well- fixed metal shell associated with an acetabular cemented augmentation is a simple and safe technique for the management of recurrent hip dislocation, for elderly patients in which it is advisable to avoid a major revision hip surgery by medical comorbidities. Nonetheless, further studies with medium-and long-term follow-up are needed to validate this technique.

Abstract: the personality disorders can be understood as theoretical constructs employed to represent different styles or patterns in which personality works maladapted to its environment. the personality styles theory of theodore millon is one of the models that aims to understand these disorders. from this theoretical model, different personality styles are proposed, as well as a tool for assessment of personality disorders, the millon clinical multiaxial inventory (mcmi), which is widely used worldwide in the research and clinical context, and a psychotherapeutic proposal, called synergistic psychotherapy.

Abstract: dysthymia is a chronic and incapacitating form of depression that affects a substantial portion of the population (3-6%) and increases the risk for major depressive disorder. it is associated with significant disabilities and high comorbidity. the nosological status of dysthymia has been associated with considerable controversy over the past decades: some investigators regard it as a mood disorder, and others as a personality disorder. currently classified among the mood disorders, dysthymia is now a treatable disorder and should receive more attention in view of its associated morbidity. the present article reviews the main historic aspects of dysthymia, its nosological features and its relationship with major depressive disorder. we conclude that further studies are necessary in order to validate the concept of dysthymia and the spectrum of chronic diseases, in order to provide a better understanding of the disorder as well as evidence-based guidelines.
Quadratic regular reversal maps
Francisco J. Solis,Lucas Jódar
Discrete Dynamics in Nature and Society , 2004, DOI: 10.1155/s1026022604311015
Abstract: We study families of quadratic maps in an attempt to understand the role of dependence on parameters of unimodal maps and its relationship with the computer-generated chaos observed in numerical simulations. Our specific goal is to give conditions on this dependence to avoid chaotic situations. We show several examples that describe in some generality the qualitative properties of quadratic maps.

Open Journal of Medical Psychology (OJMP) , 2016, DOI: 10.4236/ojmp.2016.51002
Abstract: The purpose of this survey was to investigate depressive symptoms in cancer patients and the differences based on gender, quality of life and social support. Sixty-eight patients diagnosed with cancer participated in the research, with ages varying between 25 and 83 years (A = 55.4; SD = 13.3) and 85.3% were female. The instruments used were Identification Questionnaire, Perceived Social Support Scale—adult version (EPSUS-A), Medical Outcomes Short-Form Health Survey (SF-36) and the Baptista Depression Scale Hospital—clinic version (EBADEP-HOSP-AMB). It was verified that most of the patients reported not having depression diagnosis before the cancer, nor in the current moment, besides not using anti-depressive medication. The scores obtained in the EBADEP-HOSP-AMB suggest light depressive symptoms. It is concluded that the depressive symptoms were mostly presented in women, in patients with worse mental health condition and in those less satisfied with the social support.

Abstract: This paper aims to study the efficiency of two short-term progestagen (FGA vs. MAP) + eCG treatments in estrus synchronization and artificial insemination (AI) with fresh or chilled semen in Assaf ewes fertility rate. All ewes received a subcutaneous implant of exogenous melatonin 45 days before been treated with short-term progestagens + eCG. By June 1st, ewes were divided in two groups: half was treated with an intravaginal sponge impregnated with 20 mg of FGA and the other half with an intravaginal sponge impregnated with 60 mg of MAP. Progestagen treatments lasted for 6 days. At sponge withdraw, all ewes were injected with 750 IU of eCG. Ovarian activity was assessed by plasmatic progesterone levels before and after progestagens + eCG treatment. Semen was collected by electro ejaculation and extended with Andromed or OviXcell. AI was performed 55 hours after eCG administration with fresh or chilled semen. During AI several factors were assessed: vagina mucosa color and lubrication, external cervical Os type, cervical mucous viscosity, semen deposition place and seminal cervix outflow. Semen was deposited as deep as possible without distress or trauma cervix mucosa. All Assaf ewes presented cyclic activity before progestagen + eCG treatments (2nd fortnight of May). Short-term progestagen + eCG treatments were equally efficient (100.0%). About 76.5% of Assaf ewes were pregnant 41 days after AI. Fertility rate was influenced by external Os type, semen deposition place and seminal cervix outflow. However, this rate was not conditioned by vaginal color or lubrication, cervical mucus viscosity, semen preservation technic and semen extender.
A technique to remove a well-fixed titanium-coated rm acetabular cup in revision hip arthroplasty
Fernando MJ Judas, Rui F Dias, Francisco M Lucas
Journal of Orthopaedic Surgery and Research , 2011, DOI: 10.1186/1749-799x-6-31
Abstract: In the following case report, we removed a well-fixed polyethylene titanium-coated RM acetabular cup with 20 years of follow-up, by significant wear of the polyethylene layer. The isoelastic femoral stem was also removed by mechanical failure.We report a technique for removal of the cementless acetabular cup using powered acetabular reamers. The RM cup was sequentially reamed and when the polyethylene layer was thin enough, the remaining cup was removed easily by hand tools. The acetabular bone stock is preserved and the risks of bone fractures and bleeding are minimized. To our knowledge, these principles were applied only in cemented cups.We have used this technique in 10 cases with excellent results and no complications were noted. This is a simple, reproducible, non-costly, non-timing consuming, safe and successful technique to remove well-fixed titanium-coated RM acetabular cups.The purpose of revision hip arthroplasty is to reconstruct the hip to reproduce, as closely as possible, the form and function of the native joint. The indications for revision include significant polyethylene wear, fractures of the components, component malposition, hip instability, severe thigh pain, excessive damage to the femoral Morse taper, and severe infection [1-3].In revision hip surgery, the removal of well-fixed cementless components can be extremely demanding, time consuming, and requiringes patience and caution to limit the amount of host bone destruction. Many surgeons opt to retain a well-fixed acetabular cup unless it is malpositioned or shows signs of impingement or severe wear. Fortunately, indications for implant removal are scarce, and most of the contemporary cementless components perform very well through improved bony ingrowth [4-6].Because of the diversity of the components and the methods used to secure them, an equal diversity of approaches and tools are necessary for component extraction. Component removal in total hip arthroplasty revision is a crucial and es

Abstract: the outcome questionnaire (oq-45) is an instrument designed to measure client's progress in therapy, repeatedly, during psychotherapy. it is not a theoretically oriented, and can be applied to psychotherapy of different theoretical approaches. it shows evidence of validity and internal consistency, in its original version. the aim of this work was to translate and culturally adapt the oq-45 to the context of brazilian culture. the process consists of five stages: translation, synthesis, back-translation, review by experts and pre-test. it was based on two versions: the original, in english and the portuguese. the results suggest that the oq-45 is an easy test to understand and to apply, even in people with low educational level. validity and reliability studies will be needed for the brazilian version, comparing clinical with non-clinical samples.

Abstract: objective: to determine the prevalence of depressive and anxiety symptoms in patients with rheumatoid arthritis (a chronic inflammatory disease) in comparison to a control group with osteoarthritis (a chronic non-inflammatory degenerative disease) and to identify the sociodemographic and clinical variables associated with depressive symptoms in these patients. method: sixty-two rheumatoid arthritis patients and 60 osteoarthritis patients participated in the study. sociodemographic and clinical data were collected and the hospital anxiety and depression scale and the disability index of the health assessment questionnaire were applied. results: the prevalence of depressive symptoms was of 53.2% in rheumatoid arthritis and 28.3% in osteoarthritis (p = 0.005). the prevalence of anxiety symptoms was of 48.4% in rheumatoid arthritis and 50.0% in osteoarthritis (p = 0.859). the mean (and standard deviation) scores in the disability index of the health assessment questionnaire were 1.4 (0.8) in rheumatoid arthritis and 1.4 (0.6) in osteoarthritis (p = 0.864). rheumatoid arthritis patients with depressive symptoms had lower education and higher disease activity and functional disability. conclusion: although these two rheumatic diseases are similar in terms of the pain and functional disability that they cause, a significantly higher prevalence of depressive symptoms was found in rheumatoid arthritis patients. this difference might be explained by the hypothesis of a neuroimmunobiological mechanism related to cytokines in inflammatory diseases, which has been considered as a candidate to the development of depressive symptoms.

Abstract: the aims of the study were to determine whether different glucose loads at the start of peritoneal dialysis could be negative for survival of the technique or of the patients, and to find out what factors affect them and how nursing staff can act in this regard. a retrospective study was carried out from 2004 to 2008. the sample comprised 63 patients, classified in 3 groups according to the glucose concentration. epidemiological, analytical, peritoneal transport and rinsing, comorbility and dialysis dose data were compiled. the results show that the three groups were differentiated by the total glucose weight (p=0.001), average concentration (p<0.001), serum albumin (p<0.05), and the dialysate/creatinine plasma quotient (p=0.036). there were 15 deaths, with no significant differences found for the survival of the patients between the groups (p=0.163), although first-year survival was 95.2%, 94.1% and 78.4%. the factors that influenced survival were age, cardiovascular disease, total kt/v, diuresis and albumin. failure of the technique occurred in 8 patients and there were no differences between the groups (p=0.769), nor any independent factors affecting the survival of the technique. in conclusion, we have been unable to prove that a higher initial glucose load affects the survival of the patients or of the technique.
