Les transformations du secteur de la pêche dans l'ancienne U.R.S.S (Changes of the fishing industry in the Former Soviet Union)
Authors: Carré François 
Published: May 2015

Résumé. - Grâce au lancement d'une puissante flotte de pêche dans les années 1960-1970, qui opérait partout dans l'Océan Mondial, l'URSS s'était hissée au tout premier rang des producteurs mondiaux de poisson. Mais la création des zones de 200 milles, l'épuisement de certaines ressources et surtout l'effondrement du système soviétique ont fortement perturbé ce secteur économique qui reposait pour l'essentiel sur de grosses entreprises d'Etat fortement subventionnées et tournées vers l'approvisionnement d'un marché intérieur quasiment fermé.
L'introduction de l'économie de marché a révélé la lourdeur et le vieillissement de l'outil de production, inadapté à un marché ouvert à la concurrence. L'éclatement territorial de l'URSS est une raison supplémentaire de désorganisation, puisque les républiques maritimes qui s'étaient spécialisées dans la pêche à l'époque où elles devaient ravitailler l'ensemble de l'Union, se retrouvent à la tête d'un potentiel de production disproportionné à leur marché (Républiques Baltes par exemple).
DNA Barcoding of the parasitoid wasp subfamily Doryctinae (Hymenoptera: Braconidae) from Chamela, Mexico
Authors: Gutiérrez-Arellano Daniela , Gutiérrez-Arellano Claudia , Zaldívar-Riverón Alejandro 
Published: May 2015

Background and aims. The Doryctinae is a considerably diverse, poorly studied group of parasitoid wasps and one of the most diverse subfamilies within Braconidae. Taxonomic knowledge of this group remains highly incomplete, specially in the tropics. In Mexico, it has been reported as the subfamily with the highest number of recorded genera. A preliminary Barcoding study carried out in the Chamela region, located near the Mexican pacific coast in Jalisco, identified 185 barcoding species of Dorytinae assigned to 19 identified doryctine genera. This work updates the later study, representing a three years effort to assess the species richness of this subfamily for the Chamela region.
Materials and methods. Ten collecting field trips of 5 to 10 days each were carried out from June 2009 to May 2011. A 2% divergence criterion using the BIN system implemented in BOLD was followed in order to establish species boundaries among the specimens that were collected.
Results and conclusions. A total of 961 specimens were collected, from which 883 COI sequences were obtained. The sequences generated corresponded to 289 barcoding species and 30 identified genera. The most speciose genera were Heterospilus Haliday (170 spp.), Ecphylus Förster (19 spp.), Allorhogas Gahan (15 spp.) and Callihormius Ashmead (14 spp.). Addition of previously collected material increased the diversity of the subfamily in the region to 34 genera and 290 species. Paraphyly of Heterospilus with respect to Neoheterospilus and Heterospathius was again recovered. Twenty new species and two new genera (Sabinita Belokobylskij, Zaldívar-Riverón et Martínez, Ficobolus Martínez, Belokobylskij et Zaldívar-Riverón) have been described so far from the material collected in this work.
A new checklist of lichenised, lichenicolous and allied fungi reported from South Africa
Authors: Fryday Alan M. 
Published: May 2015

Background: The last comprehensive list of lichenised, lichenicolous and allied fungi reported from South Africa was published in 1950. A checklist is important to provide basic information on the extent of the diversity, and to provide the most recent name and classification.Objective: To present a list of all the lichenised, lichenicolous and allied fungi reported from South Africa.Methods: The list presented is entirely literature based and no attempt has been made to check the report of any taxa or their status by checking the specimens upon which they are based. Firstly, all taxa that were not reported from within the modern boundaries of South Africa were excluded. Next, the Recent literature on lichens database was searched for literature on South African lichens since 1945 and all references checked for new species or new reports, which were then added to the list. These names were then checked against Index Fungorum to ensure that the most current name was being used. Finally, the list was rationalised by excluding all synonyms and dubious infraspecific taxa.Results: The current list includes 1750 taxa in 260 genera from mainland South Africa, with an additional 100 species and 23 genera from the sub-Antarctic Prince Edward Islands, which are treated separately. The replacement name Verrucaria dagolavii Fryday is proposed for Verrucaria umbilicata Øvstedal.Conclusion: It is estimated that, when fully explored, the lichen biota of South Africa will consist of somewhere between 2500 and 3000 taxa.

Purpose To investigate the prevalence of CYP1B1 mutations in Portuguese children with primary congenital glaucoma (PCG) and to study the possible correlations between the mutation status and clinical features of the disease. Methods DNA sequencing analysis of the CYP1B1 gene was used to screen 21 children with PCG followed on Paediatric Ophthalmology and Medical Genetics consultations at D. Estefania's Hospital (Centro Hospitalar de Lisboa Central, Portugal). The effect of mutations on the phenotype of the patients was also assessed. Presence and type of mutations in CYP1B1 gene, age at diagnosis, bilaterality, age at first surgery, postoperative intraocular pressure and corneal diameter, final visual acuity, number of surgical reinterventions, and number of antiglaucoma medications required postoperatively were noted. Results Mutations in the CYP1B1 gene in 6 patients (28.57%) were detected, all compound heterozygotes. Seven types of mutations were identified: c.182G>A, c.317C>A, c.535delG, c.1064_1076del, c.1159G>A, c.1310C>T, and c.1390dupT. All patients with these mutations developed bilateral PCG, whereas in the group without mutations only 7 (46.67%) showed bilateral disease. Age at diagnosis was lower in the group of patients with these mutations (0.0 ± 0.00 vs 4.5 ± 2.63 months, p<0.01). In the remaining variables (age at first surgery, postoperative intraocular pressure and corneal diameter, final visual acuity, number of surgical reinterventions and antiglaucoma medications required postoperatively), no significant differences between the groups were detected (p>0.05 for all comparisons). Conclusions This study is the first to report the variety of mutations in the CYP1B1 gene in a group of Portuguese children with PCG and to describe 2 new mutations. Genetic analysis of PCG must be carried out, although it has not yet been possible to establish a genotype-phenotype correlation, with the exception of bilaterality and early age at diagnosis.

Published: May 2015

Background and purpose The posterior soft tissue repair is 1 of the preventing factors for dislocation after total hip arthroplasty (THA). The aim of our study was to analyse THA patients with posterior soft tissue repair in terms of suture durability, time of suture failure and correlate the changes in leg length and offset postoperatively to suture durability. Methods A total of 37 consecutive THA patients operated for osteoarthritis were included in the study. The posterior repair included reattaching the piriformis, conjoined tendons and posterior capsule to the greater trochanter through 2, 2 mm drill holes with 2 grasping stitches. A metal indicator wire was stitched into the piriformis tendon at distance of 1 cm from the greater trochanter after the prosthesis had been implanted and the joint reduced. Anteroposterior radiographs were taken immediately after the patients returned from the operating theatre to the intensive care unit, the next day after mobilisation, and at the 5th day of stay and at 3 months postoperatively. Results Out of 37 THA hips, 6 (16%) had failed immediately after surgery, 25 (68%) at the 1st postoperative day after mobilisation, 2 (5%) at the 5th postoperative day, and 1 (3%) repairs had failed at 3 months after THA. In the remaining 3 hips no failure occurred. Interpretation We conclude that posterior soft tissue repair in THA often fails and suggest that new posterior soft tissue repair methods be developed.

Authors: Wang Yeming , Zhang Jianguo , Wei Wanfu 
Published: May 2015

Introduction Revision internal fixation for femoral neck nonunion in young patients can pose a surgical challenge. Hip salvage protocols include osteotomy and osteosynthesis using various implants and grafting techniques (muscle pedicle, vascularised or nonvascularised fibular graft). The purpose of this study was to evaluate the clinical outcomes of vascularised iliac grafting for femoral neck nonunion in patients younger than 50 years. Materials and methods A total of 22 patients underwent vascularised iliac grafting and internal fixations for femoral neck nonunion were retrospectively analysed. Their mean age was 36.6 years. The cases were evaluated radiographically and clinically. Results All the patients were followed-up for an average of 64.6 months. The mean time to union for all patients was 5.4 months. The mean Harris Hip Score had increased from 55.3 preoperatively to 85.2 at the latest follow-up. The average neck-shaft angle had changed from 127.4° preoperatively to 128.3° postoperatively. Postoperative progression of osteonecrosis of the femoral head was seen in 3 patients, 2 patients were pain free and 1 patient required total hip arthroplasty 9 years after the revision procedure. There was no further progression in 3 patients with preoperative radiological evidence of the femoral head osteonecrosis. Conclusions This study indicates that vascularised iliac grafting is a viable option in treatment of femoral neck nonunion in the young adult.
Correlation between the Level of Physical Activity as Measured by Accelerometer and the Harris Hip Score
Authors: Alvarez Alejandro , Domenech Julio , Valverde-Mordt Carlos , Lison Juan F. 
Published: May 2015

Background The most widely used method to assess the outcome of total hip arthroplasty (THA) is the Harris Hip Score (HHS). Patients’ expectations about the benefits of hip arthroplasty are increasing and are no longer limited to pain reduction. Patients believe they will be able to do recreational activity and sport after surgery. It is also essential to assess the level of physical activity after arthroplasty insofar as it is associated with early failure of the components. The purpose of this study is to explore correlation of the HHS with physical activity in patients with THA. Methods This is a cross-sectional study on 47 patients with THA. Correlation of HHS with the results of physical activity obtained objectively using accelerometer worn for a week and subjectively using the IPAQ questionnaire and the UCLA scale. Finding There was no correlation between the HHS and the activity measured using accelerometers, or with the IPAQ activity questionnaire. The HHS reported moderately significant correlations with the UCLA scale. Conclusions The HHS may not be as discriminatory as other instruments at assessing patient activity levels after THA.

Published: May 2015

Introduction Radiostereometric analysis (RSA) is an accurate and precise measurement tool of migration and rotation of implants. We investigated if early migration measured with RSA can be used to predict the risk of later aseptic loosening in acetabular revision surgery. Patients and methods A total of 312 patients who underwent acetabular revision surgery were followed by RSA measurements for 2 to 20 years. The endpoint was either re-revision due to aseptic loosening or loosening on last available radiographic examination. Cox regression model was used to evaluate the predictive value of early migration. Results A total of 16 acetabular cups were re-revised due to aseptic loosening and 7 unrevised cups were radiographically loose. Every mm of proximal migration 2 years postoperatively increased the risk of aseptic loosening by 37% (hazard ratio (HR) 1.37, 95% confidence interval (CI) 1.18-1.58). Adjusting for differences in base line demographics, bone defects and surgical techniques in a Cox regression model, risk of aseptic loosening with every mm of proximal migration was even higher (HR 1.94, 95% CI 1.34-2.82, p<0.001). Conclusions We found a strong relationship between early migration measured by RSA and risk of late aseptic loosening in acetabular revision surgery. Monitoring proximal migration with RSA should be considered as an essential step in quality assessment when new implants and novel techniques are introduced in acetabular revision surgery.
The Anatomy and Function of the Obturator Externus

Published: May 2015

There is limited knowledge regarding the anatomic relationships and functional anatomy of the Obturator Externus muscle (OE). It is described as a muscle which originates from the external bony margin of the obturator foramen with a cylindrical tendon which passes like a sling under the femoral neck and inserts in the trochanteric fossa. The primary aim of this study is to describe the OE morphology and its anatomic relationship to the acetabulum. A secondary aim is to postulate its action. Eighteen fresh human cadaveric hips were dissected to investigate the anatomy of the OE. A plastic model of the pelvis and femur was used to create a string model based on a technique previously described by Beck et al. The plastic model was used to determine the function of the OE. We conclude that the Obturator externus muscle helps to stabilise the head of the femur in the socket. The mechanical model demonstrated that the primary action of the obturator externus muscle was to externally rotate the femur when the hip was in neutral position and flexed at 90°. Its secondary function was as an adductor when the hip was in flexion.

Published: May 2015

Introduction Acetabular component loosening is a leading cause for revision after metal-on-metal hip resurfacing arthroplasty (MMHRA). We aimed to identify potential risk factors and determine radiographic signs associated with this mode of failure. Methods From a series of 1375 hips treated with MMHRA, 21 (20 patients) underwent revision surgery secondary to aseptic loosening of the acetabular component and 6 patients had a radiographically loose acetabular component. A control group of 27 hips (26 patients) was selected among the patients that did not have a revision, and was matched for age, gender, component size and diagnosis. Results Mean time to revision in the loosening group was 103.0 months and the mean time of follow-up in the control group was 161.4 months. We found greater activity levels, range of motion scores, and cup abduction angles in the loosening group. The centre-edge (CE) angle of Wiberg was 10° lower in the loosening group compared with the control group. In addition, 11 of the hips from the study group presented a sclerotic halo superior to the cup on the last radiograph vs. none in the control group. There was no difference in the prevalence of postoperative reaming gaps or radiographic signs of neck-cup impingement between the 2 groups. Discussion Risk factors for acetabular loosening included hip dysplasia with low CE angle, and a large cup abduction angle. The patient's level of activity influences the appearance of symptoms and the time to revision. We recommend selecting patients with a sufficient CE angle and properly orienting the cup.

Purpose Tissue engineering techniques were used to study cartilage repair over a 12-month period in a rabbit model. Methods A full-depth chondral defect along with subchondral bone injury were originated in the knee joint, where a biostable porous scaffold was implanted, synthesized of poly(ethyl acrylate-co-hydroxyethyl acrylate) copolymer. Morphological evolution of cartilage repair was studied 1 and 2 weeks, and 1, 3, and 12 months after implantation by histological techniques. The 3-month group was chosen to compare cartilage repair to an additional group where scaffolds were preseeded with allogeneic chondrocytes before implantation, and also to controls, who underwent the same surgery procedure, with no scaffold implantation. Results Neotissue growth was first observed in the deepest scaffold pores 1 week after implantation, which spread thereafter; 3 months later scaffold pores were filled mostly with cartilaginous tissue in superficial and middle zones, and with bone tissue adjacent to subchondral bone. Simultaneously, native chondrocytes at the edges of the defect started to proliferate 1 week after implantation; within a month those edges had grown centripetally and seemed to embed the scaffold, and after 3 months, hyaline-like cartilage was observed on the condylar surface. Preseeded scaffolds slightly improved tissue growth, although the quality of repair tissue was similar to non-preseeded scaffolds. Controls showed that fibrous cartilage was mainly filling the repair area 3 months after surgery. In the 12-month group, articular cartilage resembled the untreated surface. Conclusions Scaffolds guided cartilaginous tissue growth in vivo, suggesting their importance in stress transmission to the cells for cartilage repair.

Published: May 2015

Background Because of the numerous limitations of prostate-specific antigen (PSA), α-methylacyl-CoA racemase (AMACR) and hepsin have recently been suggested as potential biomarkers in prostate cancer (PC). This report presents a comparison study of the presence of AMACR and hepsin in urine collected before and after digital rectal examination (DRE) as a previously suggested diagnostic marker for PC. Methods Seventy-six urine samples (38 before and 38 after prostate massage) from patients with benign prostate hyperplasia (BPH) and 66 urine samples (33 before and 33 after prostate massage) from patients with PC were analyzed. PC was confirmed by prostate biopsy. Urinary levels of AMACR and hepsin were determined by ELISA and related to the tumor stage, Gleason score and PSA level. Results AMACR and hepsin levels in urine collected after prostate massage were higher only in the PC group. There were no correlations between AMACR levels, hepsin levels, tumor stage and Gleason score. AMACR and hepsin did not differentiate between BPH and PC with better true positive and false negative rates than serum PSA. Conclusions AMACR and hepsin were unable to diagnose PC with better true positive and false negative rates than PSA. An additional procedure combined with other markers should be applied for the reliable diagnosis of PC.

Purpose The purpose of this study is to evaluate the complications of peripherally inserted central catheters (PICCs) in orthopedic patients with chronic bone orthopedic infection. Materials and methods The institutional review board approved this retrospective study and informed consent was waived. Records of 180 consecutives PICCs placed in patients hospitalized in the orthopedic surgery department were reviewed. All patients had bones infections necessitating a long-term intravenous antibiotics therapy. All PICC complications were recorded during the patient hospitalization: infection [catheter-related bloodstream infection (CRBSI), central line associated bloodstream infection (CLABSI), exit-site infection, septic phlebitis], thrombosis, occlusion, mechanical complication (accidental withdrawal, malposition, median nerve irritation). Results One hundred and eighty PICCs were placed in 136 patients. Mean duration of catheterization was 21 days (total 3911 PICC-days). Thirty-six PICCs (20%) were removed due to complications (9.2 complications per 1000 PICC-days): 14 (8%) infections (one CRBSI ( Pseudomonas aeruginosa), one septic phlebitis ( P. aeruginosa), two exit-site infections and 10 CLABSIs), 11 (6%) occlusions, and 12 (7%) mechanical complications (10 accidental withdrawals, one malposition, one median nerve irritation). One patient had two complications simultaneously. After multivariate analysis, two risk factors were significantly associated with the overall occurrence of complications: age more than 70 years [OR = 2.89 (1.06-7.89], p = 0.04] and number of lumen at least two [OR = 2.64 (1.03-6.75), p = 0.04]. Conclusions Even in orthopedic patients with chronic orthopedic bone infection, PICCs have a low rate of complication. The increasing lumen number of the PICC is a potential risk factor in our series.

Aims To update smoking prevalence trends in Italy among adult and young populations; to determine the recent spread, particularly among young smokers, of roll-your-own (RYO) cigarettes (which cost approximately half the price of manufactured cigarettes); and to evaluate the effects of 2013 legislation increasing the minimum tobacco purchasing age from 16 to 18 years in Italy. Methods Two surveys on smoking were conducted in 2013 and 2014 in Italy, on a total sample of 6052 individuals, representative each year of the national population aged ≥15 years, where we collected data on type of tobacco most frequently smoked and on the perception of the enforcement of the tobacco sales-to-minors legislation. Results A total of 21.1% of the population surveyed were smokers (25.5% of men and 17.0% of women). Prevalence of current smoking among young participants (15-24 years) was 19.9% (21.7% of male participants and 18.0% of female participants). Overall, 6.9% of smokers, and 13.3% of young smokers, reported RYO cigarettes as the most frequently smoked tobacco product. More than 80% of Italian adults had never seen a tobacco retailer refuse to sell cigarettes to minors (i.e., aged <18 years) or request their identification or age. Conclusions Although adult and young smoking prevalence rates substantially decreased over the last few decades, neither of them have significantly changed since 2007. Use of RYO cigarettes is increasing, particularly among the young. Our study highlights the need to equalize the costs of different types of tobacco products and to improve the enforcement of the current tobacco sales-to-minors legislation.
