A non-randomized direct comparison of cognitive-behavioral short- and long-term treatment for binge eating disorder

Background: To compare treatment outcomes of a cognitive-behavioral long-term (CBT-L) and short-term (CBT-S) treatment for binge eating disorder (BED) in a non-randomized comparison and to identify moderators of treatment outcome. Methods: 76 female patients with BED participated in the study: 40 in CBT-L and 36 in CBT-S. Outcome values were compared at the end of the active treatment phase (16 sessions for CBT-L, 8 sessions for CBT-S) and at 12-month follow-up. Results: Both treatments produced significant reductions in binge eating. At the end of active treatment, but not at the end of follow-up, effects of primary outcomes (e.g. remission from binge eating, EDE shape concern) were better for CBT-L than for CBT-S. Dropout rates were significantly higher in CBT-L (35%) than in CBT-S (14%). Moderator analyses revealed that treatment efficacy for rapid responders and individuals exhibiting high scores on the mixed dietary negative affect subtype differed between the CBT-L and CBT-S with respect to objective binges, restraint eating and eating concern. Conclusion: Findings suggest that CBT in general represents an effective treatment for BED, but that subgroups of patients might profit more from a prolonged treatment. Short, lessintensive CBT treatments could nevertheless be a viable option in the treatment of BED.

Occurrence of adults and biological aspects of Geniates borelli Camerano (Coleoptera, Scarabaeidae, Rutelinae) in Aquidauana, MS, Brazil

Occurrence of adults and biological aspects of Geniates borelli Camerano (Coleoptera, Scarabaeidae, Rutelinae) in Aquidauana, Mato Grosso do Sul, Brazil. Due to the importance of Geniates borelli Camerano as a pest in many crops, studies were developed at Universidade Estadual de Mato Grosso do Sul, Aquidauana campus, MS, Brazil. Adults were collected with a light trap from January 2006 to December 2007. 3,320 adults were collected, and the highest quantities were obtained in October 2006 and November 2007, with 1,548 and 802 adults recorded, respectively. Collected adults were kept in plastic containers with soil and Brachiaria decumbens seedlings for oviposition. 535 eggs measuring 2.30 × 1.60 mm were obtained. As the embryonic development progressed, eggs increased in size to 3.00 × 2.70 mm, and this change occurred between 6 and 10 days after oviposition. The embryonic period lasted 17.9 days. The first, second, and third instars lasted 37.6, 49.7, and 74 days, respectively. The prepupal stage lasted 65.9 days and the pupal stage lasted an average of 18.5 days. The biological cycle is completed in 315.8 days, which characterizes the species as univoltine. The average longevity of females was 35.4 days and 28.5 days for males.

Safety and accuracy of robot-assisted versus fluoroscopy-guided pedicle screw insertion for degenerative diseases of the lumbar spine: a matched cohort comparison.

Object Recent years have been marked by efforts to improve the quality and safety of pedicle screw placement in spinal instrumentation. The aim of the present study is to compare the accuracy of the SpineAssist robot system with conventional fluoroscopy-guided pedicle screw placement. Methods Ninety-five patients suffering from degenerative disease and requiring elective lumbar instrumentation were included in the study. The robot cohort (Group I; 55 patients, 244 screws) consisted of an initial open robot-assisted subgroup (Subgroup IA; 17 patients, 83 screws) and a percutaneous cohort (Subgroup IB, 38 patients, 161 screws). In these groups, pedicle screws were placed under robotic guidance and lateral fluoroscopic control. In the fluoroscopy-guided cohort (Group II; 40 patients, 163 screws) screws were inserted using anatomical landmarks and lateral fluoroscopic guidance. The primary outcome measure was accuracy of screw placement on the Gertzbein-Robbins scale (Grade A to E and R [revised]). Secondary parameters were duration of surgery, blood loss, cumulative morphine, and length of stay. Results In the robot group (Group I), a perfect trajectory (A) was observed in 204 screws (83.6%). The remaining screws were graded B (n = 19 [7.8%]), C (n = 9 [3.7%]), D (n = 4 [1.6%]), E (n = 2 [0.8%]), and R (n = 6 [2.5%]). In the fluoroscopy-guided group (Group II), a completely intrapedicular course graded A was found in 79.8% (n = 130). The remaining screws were graded B (n = 12 [7.4%]), C (n = 10 [6.1%]), D (n = 6 [3.7%]), and E (n = 5 [3.1%]). The comparison of "clinically acceptable" (that is, A and B screws) was neither different between groups (I vs II [p = 0.19]) nor subgroups (Subgroup IA vs IB [p = 0.81]; Subgroup IA vs Group II [p = 0.53]; Subgroup IB vs Group II [p = 0.20]). Blood loss was lower in the robot-assisted group than in the fluoroscopy-guided group, while duration of surgery, length of stay, and cumulative morphine dose were not statistically different. Conclusions Robot-guided pedicle screw placement is a safe and useful tool for assisting spine surgeons in degenerative spine cases. Nonetheless, technical difficulties remain and fluoroscopy backup is advocated.

Chronic rejection of allogenic dermal grafts in 73 % TBSA burn patient

Rationale: Allogenic grafts are an excellent way to temporarily cover a wound. It prevents the loss of electrolytes and water, reduces the risk of infection and diminishes pain. Another advantage of the allograft is in circumventing problems such as the morbidity of skin graft donor sites. We present here the case of a patient grafted in 1991 with cultured epidermal autografts (CEA) and allogenic skin transplants on his legs, outlining the risks and potential long-term complications. Methods: The 40-year-old male patient was treated with allogenic Split Thickness Skin Graft (STSG) transplantations, CEA and Cyclosporine-A therapy. Allogenic STSG for lower extremities were harvested from a female HIV-negative organ donor. They were transplanted, de-epithelialized and subsequently covered with CEAs. Cyclosporine-A was administered systemically from the first day following transplantation until three weeks after the last CEAs were placed on the allogenic dermis. Results: Immediate results showed a 90% successful grafting under cyclosporine therapy. However, some lesions were still present 16 months later. The skin was hard with little or no elasticity. Five years after the transplantation there were no more lesions. However, a 10-year follow-up showed new ulcers on both lower extremities. All the skin of the right leg was removed and replaced by STSG from the patient's back. Postoperative results were excellent with a 100% graft take. The anatomopathology showed dermo-hypodermic tissue with fibrosis of the dermis, vasculopathy and chronic ulcers compatible with chronic rejection. Conclusion: While early functional results of the allografts may seem encouraging, their long-term evolution remains uncertain and, in this case, presents complications. The apparent antigenic effect of the dermal tissue may be controlled with long-term immunosuppression which may cause important secondary effects. Even with such treatments, 15 years after organ transplantation, about 35% of a transplant is no longer functional. It is therefore important to take these long-term observations into consideration when treating sensitive areas such as hands or a face.

Traitement chronique de l'hypertension arterielle par un inhibiteur de l'enzyme de conversion de l'angiotensine. [Chronic treatment of hypertension by an inhibitor of angiotensin converting enzyme]

Captopril, or SQ 14,225 an orally active inhibitor of angiotensin-converting enzyme, produced a significant blood pressure reduction in 26 hypertensives. This new drug, alone or combined with a diuretic, has normalized the blood pressure of the 22 patients on long-term treatment.

Sauerstoffsättigung der retinalen Gefässe bei hereditären Netzhauterkrankungen Retinal Vessel Oxygen Saturation in Patients Suffering from Inherited Diseases of the Retina.

Purpose: The aim of this study was to evaluate the oxygen saturation in patients with inherited diseases of the retina. Methods: Fundus oximetry images were taken using a retinal vessel analyser (IMEDOS Systems UG, Jena, Germany). Retinal vessel oximetry was performed in 53 eyes of 27 patients suffering from inherited retinal diseases and compared to 22 eyes of 11 healthy controls. The oxygen saturation in all four major retinal arterioles (A-SO2) and venules (V-SO2) were measured and their difference (A - V SO2) was calculated. The data were compared within groups and to controls. Results: Based on V-SO2 values, the rod-cone dystrophy group (66.46 %; SD, ± 5.09) could well be differentiated from controls 54.02 % (SD, ± 3.04), from cone-rod dystrophies 57.56 % (SD, ± 5.66), as well as from inherited maculopathies 58.42% (SD, ± 4.74). The mean A-SO2 in the rod-cone dystrophy group was increased to 98.96 % (SD, ± 6.06, p < 0.014), while in the cone-rod group and in the maculopathy group it was 92.75 % (SD, ± 3.75), respectively 94.44 % (SD ± 4.85), closer to the normal values (92.68 %; SD, ± 3.53, p > 0.05). The A - V SO2 difference, as an indirect indicator for retinal oxygen use, was reduced in the rod-cone patients, however only when the controls were taken into account (p = 0.01). Conclusion: This is to our knowledge the first study which proposes the retinal vessel oximetry to be a sensitive measure for differentiating rod-cone dystrophy patients not only from controls, but also from patients with other inherited retinal dystrophies.

Collaborative quality improvement to manage pain in acute care hospitals.

Objective. Collaborative quality improvement programs have been successfully used to manage chronic diseases in adults and acute lung complications in premature infants. Their effectiveness to improve pain management in acute care hospitals is currently unknown. The purpose of this study was to determine whether a collaborative quality improvement program implemented at hospital level could improve pain management and overall pain relief. Design.To assess the effectiveness of the program, we performed a before-after trial comparing patient's self-reported pain management and experience before and after program implementation. We included all adult patients hospitalized for more than 24 hours and discharged either to their home or to a nursing facility, between March 1, 2001 and March 31, 2001 (before program implementation) and between September 15, 2005 and October 15, 2005 (after program implementation). Setting.A teaching hospital of 2,096 beds in Geneva, Switzerland. Patients.All adult patients hospitalized for more than 24 hours and discharged between 1 to 31 March 2001 (before program) and 15 September to 15 October 2005 (after program implementation). Interventions.Implementation of a collaborative quality improvement program using multifaceted interventions (staff education, opinion leaders, patient education, audit, and feedback) to improve pain management at hospital level. Outcome Measures.Patient-reported pain experience, pain management, and overall hospital experience based on the Picker Patient Experience questionnaire, perceived health (SF-36 Health survey). Results.After implementation of the program only 2.3% of the patients reported having no pain relief during their hospital stay (vs 4.5% in 2001, P = 0.05). Among nonsurgical patients, improvements were observed for pain assessment (42.3% vs 27.9% of the patients had pain intensity measured with a visual analog scale, P = 0.012), pain management (staff did everything they could to help in 78.9% vs 67.9% of cases P = 0.003), and pain relief (70.4% vs 57.3% of patients reported full pain relief P = 0.008). In surgical patients, pain assessment also improved (53.7.3% vs 37.6%) as well as pain treatment. More patients received treatments to relieve pain regularly or intermittently after program implementation (95.1% vs 91.9% P = 0.046). Conclusion.Implementation of a collaborative quality improvement program at hospital level improved both pain management and pain relief in patients. Further studies are needed to determine the overall cost-effectiveness of such programs.

Daily energy expenditure in free-living conditions in obese and non-obese children: comparison of doubly labelled water (2H2(18)O) method and heart-rate monitoring.

OBJECTIVE: To compare the heart-rate monitoring with the doubly labelled water (2H2(18)O) method to estimate total daily energy expenditure in obese and non-obese children. DESIGN: Cross sectional study of obese and normal weight children. SUBJECTS: 13 prepubertal children: six obese (4M, 2F, 9.1 +/- 1.5 years, 47.3 +/- 9.7 kg) and seven non-obese (3M, 4F, 9.3 +/- 0.6 years, 31.8 +/- 3.2 kg). MEASUREMENTS: Total daily energy expenditure was assessed by means of the doubly labelled water method (TEEDLW) and of heart-rate monitoring (TEEHR). RESULTS: TEEHR was significantly (P < 0.05) higher than TEEDLW in obese children (9.47 +/- 0.84 MJ/d vs 8.99 +/- 0.63 MJ/d) whereas it was not different in non-obese children (8.43 +/- 2.02 MJ/d vs 8.42 +/- 2.30 MJ/d, P = NS). The difference of TEE assessed by HR monitoring in the obese group averaged 6.2 +/- 4.7%. At the individual level, the degree of agreement (difference between TEEHR and TEEDLW +/- 2s.d.) was low both in obese (-0.36, 1.32 MJ/d) and in non-obese children (-1.30, 1.34 MJ/d). At the group level, the agreement between the two methods was good in nonobese children (95% c.i. for the bias:-0.59, 0.63 MJ/d) but not in obese children (0.04, 0.92 MJ/d). Duration of sleep and energy expenditure during resting and physical activity were not significantly different in the two groups. Patterns of heart-rate (or derived energy expenditure) during the day-time were similar in obese and non-obese children. CONCLUSION: The HR monitoring technique provides an estimation of TEE close to that assessed by the DLW method in non-obese prepubertal children. In comparison with DLW, the HR monitoring method yields a greater TEE value in obese children.

Diagnosis by imaging : the case of textbooks of diseases of the nervous system (1850-1920)

Les traités scientifiques ne font que depuis peu d'années l'objet d'études en histoire des sciences. Pourtant, ces traités ont énormément à apporter car ils renseignent sur la manière de raisonner des auteurs, ainsi que sur le développement d'une discipline. Dans ce travail de doctorat, différents traités des maladies du système nerveux ont été dépouillés, notamment le traité de Sémiologie des affections du système nerveux (1914) de Jules Dejerine (1849-1917). Ce traité a été analysé de trois manières différentes. Il a tout d'abord été comparé à une édition précédente publiée sous forme de chapitre (1901), révélant un large remodelage du contenu du traité, suggérant une évolution rapide de la discipline neurologique en l'espace de quelques années. Deuxièmement, l'analyse de la Sémiologie a permis de recréer un réseau de professionnels avec qui Jules Dejerine était en contact et, en parcourant les livres publiés par ces auteurs, il a été possible de décrire de quelle manière ces auteurs se citent mutuellement. Finalement, ces livres contiennent de nombreuses illustrations, qui sont associées à la notion de « preuve » : les auteurs utilisent des images sous forme de dessins, de photographies ou de schémas qui illustrent des patients ou des pièces anatomiques pour « montrer » la maladie ou la lésion. Chaque illustration a un rôle à jouer pour décrire la lésion, montrer la progression de la maladie et elle aide le médecin à poser le diagnostic. Grâce à ces trois axes de recherche, un traité devient un outil de travail dynamique, qui évolue au fil des rééditions, influencé par les critiques et commentaires retrouvés dans d'autres traités et articles, et par les progrès accomplis dans la discipline traitée. Des, passages et certaines images de l'ouvrage circulent également de traité en traité et véhiculent l'autorité de l'auteur de ces passages et images qui en viennent à représenter la maladie. Ce transfert d'images joue également un rôle dans la standardisation du diagnostic et dans l'unification de la neurologie à travers le monde occidental au début du XXe siècle, une période charnière pour l'histoire de la médecine. -- Au début du XXe siècle, la neurologie est une jeune spécialité médicale qui se développe rapidement. Les différents médecins publient des traités, communiquent entre eux et échangent leurs données. Un traité scientifique est un outil de travail dynamique qui évolue avec les rééditions et le développement d'une discipline. Ces ouvrages recèlent toutes sortes d'informations et leur analyse ne fait que depuis peu de temps l'objet d'études en histoire des sciences. Ces traités regorgent notamment d'illustrations qui sont associées à la notion de « preuve » : les auteurs utilisent des images sous forme de dessins, de photographies ou de schémas qui représentent des patients ou des pièces anatomiques afin de « montrer » la maladie ou la lésion. Chaque illustration a un rôle à jouer pour décrire la pathologie, montrer la progression de la maladie et elle aide le médecin à poser le diagnostic. Les auteurs des traités, qui viennent d'Europe et d'Amérique du Nord, se citent mutuellement, permettant au lecteur de recréer leur réseau de professionnels au niveau international. De plus, comme ces auteurs réutilisent les observations et les illustrations des autres, celles-ci circulent de traité en traité et en viennent à représenter la maladie. Ce transfert d'images joue également un rôle dans la standardisation du diagnostic et dans l'unification de la neurologie à travers le monde occidental au début du XXe siècle, une période charnière pour l'histoire de la médecine. -- Until recently, the study of textbooks has been neglected in the history of the sciences. However, textbooks can provide fruitful sources of information regarding the way authors work and the development of a particular discipline. This dissertation reviews editions of a single textbook, the Sémiologie des affections du système nerveux (1914) by Jules Dejerine (1849-1917). This textbook enabled the description of three axes of research. Firstly, by comparing the book to a first edition published as a chapter, one can acknowledge an extensive remodeling of the content of the book, suggesting a vast increase in knowledge over time. Secondly, by looking at the authors that Dejerine quotes repeatedly, it becomes possible to recreate his professional network, to review the works of these authors and to determine how they cross-reference each other. Thirdly, these textbooks contain numerous medical illustrations, which are linked with the concept of "proof;" the authors demonstrate a willingness to "show" the lesion or the pathology by publishing an image. Drawings, schematic representations, radiographies, or photographs of patients or of anatomical preparations all have their own purpose in describing the lesion and the progression of the disease. They assist in the diagnosis of the pathology. By looking at all of these aspects, it is therefore possible to conclude that a neurological textbook is a dynamic object that evolves through re-editions, comments and references found in other textbooks and by the circulations of parts of these books, such as the images. The illustrations also carry the author's authority, since their ongoing use claims that the work by the owner of the image has been endorsed by others. At the same time, it validates the borrowers' arguments. By using medical illustrations from different authors worldwide, the authors are also making a claim to a common language, to a similar way of examining patients, and about how much they depend on medical imagery to prove their points. In that sense, by focusing upon these textbooks, one can affirm that neurology already existed as a worldwide specialty at the turn of the twentieth century. Much more than mere accompaniments to the text, images were of paramount importance to the unification of neurology.

Clinical and videofluoroscopic diagnosis of dysphagia in chronic encephalopathy of childhood

Objective To evaluate the contribution of deglutition videofluoroscopy in the clinical diagnosis of dysphagia in chronic encephalopathy of childhood. Materials and Methods The study sample consisted of 93 children diagnosed with chronic encephalopathy, in the age range between two and five years, selected by convenience among patients referred to the authors' institution by speech therapists, neurologists and gastroenterologists in the period from March 2010 to September 2011. The data collection was made at two different moments, by different investigators who were blind to each other. Results The method presented low sensitivity for detecting aspiration with puree consistency (p = 0.04). Specificity and negative predictive value were high for clinical diagnosis of dysphagia with puree consistency. Conclusion In the present study, the value for sensitivity in the clinical diagnosis of dysphagia demonstrates that this diagnostic procedure may not detect any change in the swallowing process regardless of the food consistency used during the investigation. Thus, the addition of the videofluoroscopic method can significantly contribute to the diagnosis of dysphagia.
