Authors: Ge Yihua , Cai Haiqing , Wang Zhigang 
Published: May 2016

Introduction Using limited MRI we evaluated the quality of closed reduction and prognosis in a group of patients with developmental dysplasia of the hip (DDH). Methods Limited MRI was performed on 28 DDH patients (41 hips) after closed reduction. All the hips were divided into deep and incomplete concentric reduction groups according to the femoral head-acetabular distance (FAD) and the shape of the labrum on limited MRI. The abduction angle of the hips, and the initial and final acetabular index (AI) were measured. Presence or absence of the ossification centre of the femoral head before treatment, the Tönnis classification and avascular necrosis of the femoral head and types (Bucholz and Ogden type) were recorded. The data of the 2 groups were analysed with SPSS software. Results We found no significant differences in age, gender, side, preoperative ossification centre of the femoral head, preoperative AI, decreased postoperative AI and abduction angles of hips between the 2 groups. There were significant statistical differences in the preoperative Tönnis grade, FAD after reduction, AI at the final follow-up, severe residual deformity and severe avascular necrosis of the femoral head (p<0.05). The cure rate showed a significant trend (p = 0.052). Conclusions Limited MRI enables effective determination of the quality of reduction immediately after closed reduction. The prognosis of the deep concentric reduction group was better than the group with incomplete concentric reduction.

Objective Compared to sagittal pelvic tilt, only a few studies have examined axial rotation on anteroposterior radiographs. We therefore quantified 3-D pelvic rotation using the width and height ratio of the obturator foramina under the various pelvic tilts. Methods Using CT reconstructions of 10 healthy pelvises, anterior pelvic planes (APPs) were rotated by 20° in 5° increments on the axial plane with various degrees of sagittal pelvic tilt. The correlation between the pelvic rotation angle and the width ratio (WR) in the axial plane and the height/width ratio (H/W) in the sagittal plane were examined. Results Axial pelvic rotation and WR showed a high linear correlation regardless of the sagittal tilt, with the correlation coefficient ranging from 0.93 to 0.98 in males and 0.87 to 0.95 in females. The angle that resulted in a WR of 1:2 was approximately 13° in males and 18° in females. H/W also showed a linear regression with sagittal tilt. Axial rotation was determined by the following equation incorporating pelvic tilts; axial rotation (male:female) = (19.9:24.2) + (2.1:3.6) × Hright/Wright + (0.9:1.5) × Hleft/Wleft - (23.2:25.1) × WR. Conclusions Pelvic tilt and rotation could be quantified by the equation using width and height ratios of the obturator foramina on a plain anteroposterior radiograph. Width and height ratios of the obturator foramina proved to be useful parameters in clinical practice for understanding pelvic rotation.

Background The aim of this study was to compare return to sport activity between a short femoral cementless stem and a conventional femoral cementless stem in total hip arthroplasty in patients 50 years old and younger. Methods We retrospectively reviewed 55 patients (61 hips) treated with a short femoral cementless stem and 28 patients (32 hips) treated with a conventional femoral cementless stem 50 years old and younger from December 2009 and December 2014. Their mean age was 39.86 (22-49) years and 38.68 (18-49) years, respectively. The mean follow-up was 54.1 (15-68) months and 52.7 (15-72) months, respectively. They were pre- and postoperatively evaluated by the clinical and radiological examination. Results No patients with the short stem had intraoperative fracture, but 1 patient with the conventional stem had intraoperative fracture. At final follow-up, there was no statistically significant difference in Harris Hip Score, and radiographic review level between 2 stems. No hip with the short stem had thigh pain, but 6 hips with the conventional stem had thigh pain at the final follow-up. No component was revised for aseptic loosening in either group. There were no differences observed in the return to sports activity between the 2 groups. Conclusions Our study demonstrated that both short cementless stem and conventional cementless stem provided stable fixation and achieved a satisfactory result in patients 50 years old and younger. There is no difference in return to sports activity level after the procedure.
HIP Osteochondral Lesions: Arthroscopic Evaluation
Authors: Fontana Andrea , Mancini Donato , Gironi Antonello , Acerbi Alberto 
Published: May 2016

Background Hip arthroscopy has allowed the diagnosis and treatment of chondral injuries. Methods We retrospectively analysed the intraoperative data of 359 patients treated with hip arthroscopy from January 2012 to December 2013. We estimated the frequency, location and extension of acetabular cartilage (AC) injuries and their correlation to femoroacetabular impingement (FAI). Results Grade 1 and 2 acetabular chondral lesions were not statistically significant in incidence, location and extension. Chondral lesions were absent on the acetabulum in 3.9% of cases, significantly lower compared to the femoral head (32.0%). 101 (28.1%) were affected by an acetabular chondral lesion. In 244 (68.0%) the chondral lesion was located on both acetabulum and femoral head. On the acetabulum, peripheral superior and superior-posterior area were frequently involved. Grade 4 acetabular chondral defects showed a significant high location on the superior-anterior, superior and superior-posterior area, involving both the peripheral and central surface. Delamination was present in 113 (31.5%) patients. Patients affected by acetabular delamination showed a reduced injury extension if compared to grade 3 or 4. 81 patients (25%) revealed acetabular chondral lesions grade 2a, 3 and 4 without any radiological, clinical or arthroscopic sign of FAI. Conclusions Location, extension and degree of hip chondral lesions show a progression toward a progressive degeneration. The high percentage of chondral delamination in the hip must be taken in consideration. The presence of symptomatic chondral lesion in cases with no radiological evidence of FAI, suggests that their aetiopathogenesis could be related to biomechanical alterations.

Published: May 2016

Introduction Femoroacetabular impingement (FAI) has been proposed as a possible cause of early osteoarthritis of the hip. The treatment of this condition and its related lesions can be performed by 3 methods: surgical dislocation of the hip; pure arthroscopic; and anterior mini-open technique with or without arthroscopic assistance. Methods We describe the anterior mini-open technique and report our experience over the last decade in the treatment of FAI and different associated pathologies of the hip. Results This technique was found to be safe and reliable, allowing tissue preservation and providing a clinical improvement similar to the purely arthroscopic-treated patient, even in complex cases. Discussions According to our experience there are several presentations of FAI and associated hip conditions, where other authors advocate surgical dislocation, which can be conducted through a mini-open approach when increased surgical skills are reached. Moreover, this technique was found to be useful as an additional tool to consider, even for surgeons involved in the arthroscopic learning curve.

Purpose Adult granulosa cell tumor (AGCT) of ovary is a rare tumor and usually has a benign course. Due to its indolent nature, recurrences are observed in a wide period and data on management of recurrences in AGCT are relatively sparse. We aimed to evaluate the clinical features, management, and survival of patients with recurrent AGCT. Methods The data of 144 patients with AGCT treated in Etlik Zubeyde Hanim Teaching and Research Hospital between 1990 and 2013 were retrospectively evaluated. Patients with radiologic or pathologic recurrences were included in the analysis. Results A total of 18 patients (12.5%) with recurrent AGCT were included. Median follow-up was 97.5 months (range 6-255 months). A total of 16 patients underwent salvage surgery and maximal debulking was achieved in 13 patients. Ten patients had unifocal and 8 had multifocal tumors. Maximal debulking could be achieved in all patients with unifocal recurrence. On the other hand, maximal debulking could only be obtained in 3 patients (37%) with multifocal recurrence (p = 0.031). Multifocality of recurrent disease and the presence of residual tumor after surgery were associated with diminished progression-free survival and overall survival (31 vs 207 months, p = 0.031; and 22 vs 220 months, p = 0.005, respectively). Conclusions Multifocal recurrence and suboptimal surgery were related with poor survival outcomes in patients with AGCT recurrence. Surgical treatment of recurrent AGCT should aim to achieve no visible disease.

Ductal adenocarcinoma is a rare subtype of prostate cancer with a worse prognosis. Histologically, it is characterized by the presence of tall, pseudostratified columnar epithelium with abundant cytoplasm organized in a papillary or cribriform-papillary pattern. Several clinical differences distinguish this subtype of prostate cancer by the conventional acinar adenocarcinoma: exophytic growth into the prostatic urethra, different clinical presentation, different sites of metastasis and more aggressiveness. The rarity of this tumour forced to base our knowledge on small case series or on individual case reports, and does not help to establish appropriate guidelines. Therefore, the diagnosis of this tumour masks clinical implications that are still not well-understood. We report the case of a 69-year-old Caucasian man with a diagnosis of pure prostate ductal adenocarcinoma that early developed multiple metastases after radical prostatectomy. The patient started hormonal therapy with a fast biochemical and radiologic (positron emission tomography–computed tomography, PET-CT) hormonal escape. Therefore, we took the decision to perform chemotherapy with Taxotere along with prednisolone with a relative stability of prostate-specific antigen (PSA) level, but a new PET-CT scan showed a further progression of the disease. Finally, the patient underwent therapy with Abiraterone acetate that did not stop the cancer progression. No therapeutic options available showed a good control of disease progression. PSA proved to be a poor marker while, on the contrary, PET-CT scan has proved to be particularly useful in the management of the disease progression. More efforts are required to add new knowledge about this tumour and assess what is known until now.

Authors: Mattioli Stefano , Picinotti Alessandro , Burgio Andreina 
Published: May 2016

Introduction The primary bladder neck obstruction (PBNO) has been recognized in 41-45% of young men suffering from a chronic lower urinary tract symptom (LUTS). Few studies are published in the literature about the use of laser devices in the surgical treatment of PBNO and none about the use of Thulium laser. The aim of our study is to report the results of our follow-up in the endoscopic treatment of PBNO with Thulium laser. Materials and methods From January 2012 to January 2015, we treated 214 patients using Thulium laser for primary bladder neck sclerosis. All patients had symptoms suggestive of LUTS or prostatism: filling or irritative symptoms and voiding or obstructive symptoms. In 157 patients, the incision was performed unilaterally at 7 o'clock of the bladder neck. In 57 cases, bilateral incision was performed at 5 and 7 o’ clock without vaporizing the tissue between the two incisions. We chose to make the incision bilaterally in cases wherein a single incision was not enough to solve the obstruction from the bladder neck and prevent a recurrence. Bladder irrigation was used overnight in all cases, and the catheter was removed after 24 hours. Results One hundred ninety-six patients enrolled completed 1-year follow-up: 157 patients underwent unilaterally incision and 39 bilateral incision. In 179 cases (91.3%), there was unchanged antegrade ejaculation, while reduced semen volume was reported by 14 men (7.1%) and retrograde ejaculation by only 3 (1.5%), but these patients underwent bilateral incision. The quality of orgasm and sexual satisfaction was not permanently changed by the operation. Conclusions In patients with PBNO, it is possible to perform endoscopic treatment with Thulium laser that we think is an effective and safe procedure, not affecting sexual functioning and particularly retrograde ejaculation.
Review of non-Welsh residents' unintentional injuries presenting to an Emergency Department in South Wales: A nine-year retrospective study
Authors: Battle Ceri E , Evans Vanessa , Evans Phillip A 
Published: May 2016

Background: Non-residents visiting an area often have limited local knowledge of the natural environmental conditions, exacerbating their risk of unintentional injuries. The aim of this study was to determine the impact of unintentional injuries of non-Welsh residents presenting to the Emergency Department of a regional trauma unit in South Wales. Methods: A retrospective hospital database review was undertaken from 2006 to 2014. All patients presenting to the ED with a non-Welsh postcode, with a diagnosis of unintentional injury were included in the study. Data collected included age, sex, time of year of presentation, injury mechanism, body part injured and patient outcome. Descriptive data were recorded and analysed. Results: From 2006 to 2014, overall attendance of non-Welsh residents to the ED was 4323. A total of 2961 (68%) patients were male, with a median age of 28 (IQR: 18–47). The most common time of year for non-Welsh resident presentations to the ED was the summer. A mechanical fall was the most commonly reported mechanism of injury. There was a significantly higher prevalence of mechanical falls and alleged assaults in the non-resident cohort, when compared to residents presenting with unintentional injuries (both p < 0.001). Conclusions: This is the first study to investigate unintentional injuries of non-Welsh residents and their impact on an ED in the UK. Further prospective research is needed in order to investigate whether the introduction of new public health policies impact on ED services in tourist areas in the UK.

Published: May 2016

Regional blocks provide adequate analgesia in trauma patients. The aim of this study was to review the current practice of emergency department physicians in the use of regional blocks.
A cross-sectional survey was conducted among emergency department physicians and anesthesiologists. The response rate was 100% (n = 107). 79% (n = 57) of the anesthesiologists were found to provide regional blocks however, 48.5% (n = 17) of emergency physicians administer local blocks. Only 2.8% of emergency physicians held a formal qualification in regional anesthesia.
There is a need to train ED physicians in regional blocks so that the pain in trauma patients can be managed early.
A questão técnica e a condição humana em Hannah Arendt e Karl Marx
Authors: Vieira Júlia Lemos 
Published: May 2016

resumo: A crítica de Hannah Arendt a Karl Marx perpassa a questão da técnica. Arendt sugerira que Marx contribuíra para a elevação do animal laborans à condição humana moderna quando indicou que a emancipação humana estaria na vitória dos trabalhadores. Empreenderemos uma refutação à crítica de Arendt, indicando que Marx recusa a tradicional cisão entre vida ativa e vida contemplativa, para se opor à alienação do homem no labor, e não o contrário. Indicaremos, assim, que Marx estava mais próximo de Arendt do que ela imaginava, dado ter criticado justamente a redução do homem a uma atividade que acaba por dar a todas as demais atividades uma forma meramente utilitária. Para ambos é preciso evitar empreender uma inversão hierárquica do pensar sobre o agir.abstract: Hannah Arendt’s critique to Karl Marx permeates the question of technique. Arendt suggested that Marx had contributed to elevate the animal laborans to the modern human condition when he indicated that human emancipation would lie in the workers’ victory. This text affords a rebuttal to this criticism of Arendt, indicating that Marx refuses the traditional split between vita activa and vita contemplativa in order to oppose the alienation of man to labor. We will indicate that Marx was closer to Arendt than she imagined, since he rightly criticized the reduction of man to an activity that ends up giving to all other activities a purely utilitarian form. To both of them it is necessary to avoid undertaking a hierarchical reversal of thinking over acting.
Intencionalidade e técnica(s)
Authors: A. Baldissera Márcia 
Published: May 2016

Resumo: A técnica é a ação de um agente Intencional, com uma determinada finalidade, sobre específicas propriedades físicas, ação que constitui um objeto técnico. O reconhecimento desta Intencionalidade da ação dos autores da técnica é necessário para o processo de compreensão desses objetos pelos receptores, principalmente para a compreensão dos objetos técnicos caracterizados também como suportes semióticos. A minha hipótese é que essa Intencionalidade pode vir “mascarada” pela própria ação técnica constituinte da forma do objeto, e também pelo discurso institucional, dificultando a compreensão desses objetos pelo público. Trata-se também de esclarecer quais as propriedades que são realmente ontológicas nos objetos técnicos.Abstract: A technique is an action of an Intentional agent, with a determined purpose, upon specific physical properties. This action constitutes a technical object. Identifying the Intentionality of authors' actions is necessary for the comprehension of these objects by receivers, particularly for the comprehension of technical objects which are also characterized as semiotic supports. My hypothesis is that this Intentionality can be “disguised” by the technical action itself, particularly in questions of form, and also by institutional discourse, which problematizes the comprehension of these same objects by the public. It will be a matter as well of clarifying the ontological properties of technical objects.
O Galo e a Coruja - a propósito de Para a Critica da Filosofia do Direito de Hegel (Introdução ) (1844), de Marx, e de algumas dificuldades originárias do projeto marxiano
Authors: Fausto Ruy 
Published: May 2016

O presente artigo – que se ocupa de um dos textos que Marx publicou em 1844, nos Anais Franco-alemães – é, em primeiro lugar (mas não só) uma análise de forma, que tem como objeto tanto a ordem de razões como a estrutura do texto de Marx – duas coisas que aqui se distinguem – como também certa contradição interna, que nele se manifesta, entre o projeto e a sua realização. O artigo dos Anais... está centrado nos problemas da revolução (da revolução na Alemanha, particularmente) e da filosofia (em particular, no da realização da filosofia, a qual seria ao mesmo tempo a sua “negação“). Esses temas, no centro dos quais está a noção de “critica“, são, no presente texto, objeto de um desenvolvimento tanto regressivo como progressivo, desenvolvimento que vai ao encontro, respectivamente, do pensamento de Feuerbach, no século XIX (com suas referências ao século XVIII), e dos frankfurtianos, no século XX. O que conduz, finalmente, a um balanço e a uma avaliação tanto do artigo dos Anais... como do projeto marxiano em geral, iluminada pela experiência de mais de um século e meio de história.
Uniaxial crystal growth in thin film by utilizing supercooled state of mesogenic phthalocyanine
Authors: Ramananarivo Mihary Fiderana , Higashi Takuya , Ohmori Masashi , Sudoh Koichi , Fujii Akihiko , Ozaki Masanori 
Published: May 2016

Abstract
A method of uniaxial crystal growth in wet-processed thin films of the mesogenic phthalocyanine 1,4,8,11,15,18,22,25-octahexylphthalocyanine (C6PcH2) is proposed. It consists of applying geometrically linear thermal stimulation to a supercooled state of liquid crystalline C6PcH2. The thin film showed highly ordered molecular stacking structure and uniaxial alignment over a macroscopic scale. An explanation of the crystal growth mechanism is suggested by taking into account the temperature range of crystal growth and the hysteresis property of C6PcH2 in the phase transition.

Published: May 2016

Abstract
The magnetic anisotropy of the Pt/Co system under ionic liquid gating was studied. A comparison of results obtained using samples under the gating and those subjected to mild oxidization by oxygen plasma ashing suggested that the anodic oxidization of the Co layer could be one of the causes of the large modulation observed in the magnetic anisotropy. However, the charge accumulation effect was probably dominant when the Co layer was on the cathode side. The experiments presented here are expected to aid in elucidating the mechanism by which electric fields affect magnetism.
Effects of annealing on the electrical characteristics of GaAs/GaAs junctions by surface-activated bonding
Authors: Chai Li , Liang Jianbo , Shigekawa Naoteru 
Published: May 2016

Abstract
The electrical properties of GaAs/GaAs junctions fabricated by surface-activated bonding (SAB) and annealing were examined on the basis of the charge neutral level model. The potential barrier height, the density of interface states, and the charge neutral level at GaAs/GaAs interfaces were estimated from the measured dependences of the electrical conductance of n-GaAs/n-GaAs and p-GaAs/p-GaAs junctions on ambient temperature. The barrier height and the density of interface states were lowered by increasing the annealing temperature to 400 °C, which suggested that the damage introduced during the SAB process was partly reduced.
