Published: September 2015

CelCelem badania było ustalenie, czy pacjenci chorzy na typ przeczyszczający bulimii i / lub nie - bulimii, leczeni inhibitorem wychwytu zwrotnego serotoniny, SI- 5 -HT (fluoksetyna), mają erozję zębów i zmiany w wybranych składnikach buforowych śliny przyusznej (wodorowęglany, fosforany, mocznik), w stosunku do zdrowej populacji.MetodaKontrolowane badanie kliniczne zostało zaprojektowane dla trzech, dopasowanych co do wieku i płci (młode kobiety) grup 94 pacjentek: z bulimią otrzymujących fluoksetynę 40 mg/dzień, niebulimicznych pacjentek z diagnozą afektywnych zaburzeń dwubiegunowych otrzymujących fluoksetynę 20 mg/dzień i zdrowej grupy kontrolnej. Ślinę ze ślinianki przyusznej pobierano od pacjentów za pomocą kapsuły Lashley’a w spoczynku i po stymulacji chemicznej 3% roztworem kwasu cytrynowego. W badaniu klinicznym określono erozję jako utratę powierzchni zębów poprzez wskaźnik (TWI). W wyselekcjonowanej ślinie oznaczono całkowite stężenia fosforanów nieorganicznych, wodorowęglanów, mocznika i pH.WynikiU pacjentów z bulimią stwierdzono wyższy indeks TWI (24%) oraz niższy poziom pH, wodorowęglanów i fosforanów w ślinie. Nie było istotnych różnic w stężeniu mocznika.WnioskiUtrata tkanek zęba o typie erozyjno – abrazyjnym wydaje się być istotnym narzędziem diagnostycznym w bulimii. Występowanie zmian w strukturze zębów może być związana z utratą ochronnej funkcji śliny, czego dowodem jest zmniejszenie wartości pH i stężeń jonów buforujących. U osób z żarłocznością psychiczną o typie przeczyszczającym, leczonych długoterminowo lekami z grupy SI-5-HT wskazany jest monitoring parametrów ślinowych, takich jak szybkość wydzielania śliny, pH, składniki buforowe oraz regularna stomatologiczna kontrola stanu tkanek jamy ustnej.

CelAnaliza powiązań pomiędzy oceną bieżących relacji rodzinnych w rodzinach pacjentek z diagnozą zaburzeń odżywania się a oceną relacji w rodzinach pochodzenia ich rodziców.Metoda54 pacjentki z anoreksją restrykcyjną, 22 pacjentki z anoreksją żarłoczno-wydalającą, 36 pacjentek z bulimią. Uwzględniono 2 grupy kontrolne: 36 pacjentek z zaburzeniami depresyjnymi oraz 85 uczennic ze szkól krakowskich. Badaniem objęci byli również rodzice dziewcząt.
Metoda: Skala Rodziny Pochodzenia oraz Kwestionariusz Oceny Rodziny FAM (wersja polska).WynikiW rodzinach uczennic szkół krakowskich lepsza ocena doświadczeń autonomii i bliskości z rodzin pochodzenia rodziców badanych dziewcząt wiązała się z ich oraz ich dzieci korzystniejszą percepcją relacji w obecnej rodzinie nuklearnej. Szczególnie znacząca okazała się transgeneracyjna percepcja doświadczeń ojców. We wszystkich grupach klinicznych zaobserwowano jedynie kilka istotnych statystycznie korelacji. U rodziców badanych pacjentek widoczny jest nikły związek oceny bieżących relacji małżeńskich z doświadczeniami transgeneracyjnymi, oraz istotny związek doświadczeń transgeneracyjnych z oceną relacji z córkami.WnioskiStwierdzono brak specyficznych powiązań pomiędzy oceną relacji transgeneracyjnych rodziców i percepcją bieżących relacji w rodzinie nuklearnej w grupie zaburzeń odżywania się. Wyniki w grupie zaburzeń odżywania się sugerują, że relacje rodziców z córkami charakteryzują się większą intensywnością niż relacje małżeńskie.
Hypercalcaemia following the use of antibiotic-eluting absorbable calcium sulphate beads in revision arthroplasty for infection
Authors: Kallala R. , Haddad F. S. 
Published: September 2015

Periprosthetic joint infection (PJI) is a devastating complication for patients and results in greatly increased costs of care for both healthcare providers and patients. More than 15 500 revision hip and knee procedures were recorded in England, Wales and Northern Ireland in 2013, with infection accounting for 13% of revision hip and 23% of revision knee procedures. We report our experience of using antibiotic eluting absorbable calcium sulphate beads in 15 patients (eight men and seven women with a mean age of 64.8 years; 41 to 83) as part of a treatment protocol for PJI in revision arthroplasty. The mean follow-up was 16 months (12 to 22). We report the outcomes and complications, highlighting the risk of hypercalcaemia which occurred in three patients. We recommend that serum levels of calcium be routinely sought following the implantation of absorbable calcium sulphate beads in orthopaedic surgery.

The terminal branches of the medial femoral circumflex artery
Authors: Lazaro L. E. , Klinger C. E. , Sculco P. K. , Helfet D. L. , Lorich D. G. 
Published: September 2015

This study investigates and defines the topographic anatomy of the medial femoral circumflex artery (MFCA) terminal branches supplying the femoral head (FH). Gross dissection of 14 fresh–frozen cadaveric hips was undertaken to determine the extra and intracapsular course of the MFCA’s terminal branches. A constant branch arising from the transverse MFCA (inferior retinacular artery; IRA) penetrates the capsule at the level of the anteroinferior neck, then courses obliquely within the fibrous prolongation of the capsule wall (inferior retinacula of Weitbrecht), elevated from the neck, to the posteroinferior femoral head–neck junction. This vessel has a mean of five (three to nine) terminal branches, of which the majority penetrate posteriorly. Branches from the ascending MFCA entered the femoral capsular attachment posteriorly, running deep to the synovium, through the neck, and terminating in two branches. The deep MFCA penetrates the posterosuperior femoral capsular. Once intracapsular, it divides into a mean of six (four to nine) terminal branches running deep to the synovium, within the superior retinacula of Weitbrecht of which 80% are posterior. Our study defines the exact anatomical location of the vessels, arising from the MFCA and supplying the FH. The IRA is in an elevated position from the femoral neck and may be protected from injury during fracture of the femoral neck. We present vascular ‘danger zones’ that may help avoid iatrogenic vascular injury during surgical interventions about the hip. Cite this article: Bone Joint J 2015;97-B:1204–13.

Published: September 2015

Infection is a leading indication for revision arthroplasty. Established criteria used to diagnose prosthetic joint infection (PJI) include a range of laboratory tests. Leucocyte esterase (LE) is widely used on a colorimetric reagent strip for the diagnosis of urinary tract infections. This inexpensive test may be used for the diagnosis or exclusion of PJI. Aspirates from 30 total hip arthroplasties (THAs) and 79 knee arthroplasties (KA) were analysed for LE activity. Semi-quantitative reagent strip readings of 15, 70, 125 and 500 white blood cells (WBC) were validated against a manual synovial white cell count (WCC). A receiver operating characteristic (ROC) curve was constructed to determine the optimal cut-off point for the semi-quantitative results. Based on established criteria, six THAs and 15 KAs were classified as infected. The optimal cut-off point for the diagnosis of PJI was 97 WBC. The closest semi-quantitative reading for a positive result was 125 WBC, achieving a sensitivity of 81% and a specificity of 93%. The positive and negative predictive values of the LE test strip were 74% and 95% respectively. The LE reagent strip had a high specificity and negative predictive value. A negative result may exclude PJI and negate the need for further diagnostic tests. Cite this article: Bone Joint J 2015;97-B:1232–6.
Implant-associated mycobacterium tuberculosis infection following surgical management of fractures
Authors: Mahale Y. J. , Aga N. 
Published: September 2015

In this retrospective observational cohort study, we describe 17 patients out of 1775 treated for various fractures who developed mycobacterium tuberculosis (MTB) infection after surgery. The cohort comprised 15 men and two women with a mean age of 40 years (24 to 70). A total of ten fractures were open and seven were closed. Of these, seven patients underwent intramedullary nailing of a fracture of the long bone, seven had fractures fixed with plates, two with Kirschner-wires and screws, and one had a hemiarthroplasty of the hip with an Austin Moore prosthesis. All patients were followed-up for two years. In all patients, the infection resolved, and in 14 the fractures united. Nonunion was seen in two patients one of whom underwent two-stage total hip arthroplasty (THA) and the other patient was treated using excision arthoplasty. Another patient was treated using two-stage THA. With only sporadic case reports in the literature, MTB infection is rarely clinically suspected, even in underdeveloped and developing countries, where pulmonary and other forms of TB are endemic. In developed countries there is also an increased incidence among immunocompromised patients. In this paper we discuss the pathogenesis and incidence of MTB infection after surgical management of fractures and suggest protocols for early diagnosis and management.

This study compared the clinical outcomes following mini-open rotator cuff repair (MORCR) between early mobilisation and usual care, involving initial immobilisation. In total, 189 patients with radiologically-confirmed full-thickness rotator cuff tears underwent MORCR and were randomised to either early mobilisation (n = 97) or standard rehabilitation (n = 92) groups. Patients were assessed at six weeks and three, six, 12 and 24 months post-operatively. Six-week range of movement comparisons demonstrated significantly increased abduction (p = 0.002) and scapular plane elevation (p = 0.006) in the early mobilisation group, an effect which was not detectable at three months (p > 0.51) or afterwards. At 24 months post-operatively, patients who performed pain-free, early active mobilisation for activities of daily living showed no difference in clinical outcomes from patients immobilised for six weeks following MORCR. We suggest that the choice of rehabilitation regime following MORCR may be left to the discretion of the patient and the treating surgeon. Cite this article: Bone Joint J 2015;97-B:1257–63.
Do you have an infection problem?
Authors: Patel A. , Pavlou G. , Ahmad R. A. , Toms A. 
Published: September 2015

In England and Wales more than 175 000 hip and knee arthroplasties were performed in 2012. There continues to be a steady increase in the demand for joint arthroplasty because of population demographics and improving survivorship. Inevitably though the absolute number of periprosthetic infections will probably increase with severe consequences on healthcare provision. The Department of Health and the Health Protection Agency in United Kingdom established a Surgical Site Infection surveillance service (SSISS) in 1997 to undertake surveillance of surgical site infections. In 2004 mandatory reporting was introduced for one quarter of each year. There has been a wide variation in reporting rates with variable engagement with the process. The aim of this article is to improve surgeon awareness of the process and emphasise the importance of engaging with SSISS to improve the quality and type of data submitted. In Exeter we have been improving our practice by engaging with SSISS. Orthopaedic surgeons need to take ownership of the data that are submitted to ensure these are accurate and comprehensive.

Published: September 2015

This study compared the quality of reduction and complication rate when using a standard ilioinguinal approach and the new pararectus approach when treating acetabular fractures surgically. All acetabular fractures that underwent fixation using either approach between February 2005 and September 2014 were retrospectively reviewed and the demographics of the patients, the surgical details and complications were recorded.A total of 100 patients (69 men, 31 women; mean age 57 years, 18 to 93) who were consecutively treated were included for analysis. The quality of reduction was assessed using standardised measurement of the gaps and steps in the articular surface on pre- and post-operative CT-scans.There were no significant differences in the demographics of the patients, the surgical details or the complications between the two approaches. A significantly better reduction of the gap, however, was achieved with the pararectus approach (axial: p = 0.025, coronal: p = 0.013, sagittal: p = 0.001).These data suggest that the pararectus approach is at least equal to, or in the case of reduction of the articular gap, superior to the ilioinguinal approach.This approach allows direct buttressing of the dome of the acetabulum and the quadrilateral plate, which is particularly favourable in geriatric fracture patterns.Cite this article: Bone Joint J 2015;97-B:1271-8.
Challenges in reporting surgical site infections to the national surgical site infection surveillance and suggestions for improvement
Authors: Singh S , Davies J , Sabou S , Shrivastava R , Reddy Srinivasulu 
Published: August 2015

Introduction Mandatory orthopaedic surgical site infection (SSI) data in England are used as a benchmark to compare infection rates between participating hospitals. According to the national guidelines, trusts are required to submit their data for at least one quarter of the year but they are free to report for all quarters. Owing to this ambiguity, there is a concern about robust reporting across trusts and therefore the accuracy of these data. There is also concern about the accuracy of collection methods. The aim of this five-year retrospective study was to assess the accuracy of SSI reporting at two hospitals in South East England under the same trust. Methods A retrospective review was carried out of five years of electronic medical records, microbiology data and readmission data of all patients who underwent hip and knee replacement surgery at these hospitals. These data were validated with the data submitted to Public Health England (PHE) and any discrepancy between the two was noted. Results A significant difference was found in the SSI rates reported by the surveillance staff and our retrospective method. Conclusions Our study confirms the findings of a national survey, which raised concerns about the quality of SSI reporting and the usefulness of PHE SSI data for benchmarking purposes. To our knowledge, there are no previously published studies that have looked at the accuracy of the English orthopaedic SSI surveillance. In the light of our findings, there is an urgent need for external validation studies to identify the extent of the problem in the surveillance scheme. The governing bodies should also issue clear guidelines for reporting SSIs to maintain homogeneity and to present the true incidence of SSI. We suggest some measures that we have instituted to address these inadequacies that have led to significant improvements in reporting at our trust.

AbstractBACKGROUNDCombined testing of high-sensitivity cardiac troponin T (hs-cTnT) and copeptin at presentation provides a very high—although still imperfect—negative predictive value (NPV) for the early rule-out of acute myocardial infarction (AMI). We hypothesized that a second copeptin measurement at 1 h might further increase the NPV.METHODSIn a prospective diagnostic multicenter study, we measured hs-cTnT and copeptin concentrations at presentation and at 1 h in 1439 unselected patients presenting to the emergency department with suspected AMI. The final diagnosis was adjudicated by 2 independent cardiologists blinded to copeptin concentrations. We investigated the incremental value of 1-h copeptin in the rule-out setting (0-h hs-cTnT negative and 0-h copeptin negative) and the intermediate-risk setting (0-h hs-cTnT negative and 0-h copeptin positive).RESULTSThe adjudicated diagnosis was AMI in 267 patients (18.6%). For measurements obtained at presentation, the NPV in the rule-out setting was 98.6% (95% CI, 97.4%–99.3%). Whereas 1-h copeptin did not increase the NPV significantly, 1-h hs-cTnT did, to 99.6% (95% CI, 98.7%–99.9%, P = 0.008). Similarly, in the intermediate-risk setting (NPV 92.8%, 95% CI, 88.7%–95.8%), 1-h copeptin did not significantly increase the NPV (P = 0.751), but 1-h hs-cTnT did, to 98.6 (95% CI, 96%–99.7%, P &lt; 0.001).CONCLUSIONSOne-hour copeptin increased neither the safety of the rule-out process nor the NPV in the intermediate-risk setting. In contrast, the incremental value of 1-h hs-cTnT was substantial in both settings. ClinicalTrials.gov/NCT00470587

Strategic Delay in Global Games
Authors: Larson Nathan 
Published: September 2015

AbstractWe study strategic uncertainty in an investment coordination game when players have the option to delay acting. Absent the option to delay, the global games literature shows that efficient equilibrium outcomes are possible only when they are also risk dominant. In contrast, we show that when delay is not too costly, strategic uncertainty can encourage delay in such a way that efficient investment occurs whenever it is “worth waiting for.”
Chiral separation of α-cyclohexylmandelic acid enantiomers using ionic liquid/salt aqueous two-phase system
Authors: Chen Lei-Lei , Li Fen-Fang , Tan Zhi-Jian 
Published: September 2015

AbstractIn this paper, an ionic liquid-based aqueous two-phase system (ILATPS) was applied to the chiral separation of α-cyclohexylmandelic acid (α-CHMA) enantiomers with hydroxypropyl-β- cyclodextrin (HP-β-CD) as the chiral selector. Several influencing parameters were investigated including the types and concentration of ionic liquids, the amount of phase-forming salt, temperature, mixing time, pH, and the content of HP-β-CD. The results showed that not all ILATPS had the ability to chirally recognise the selected enantiomers and that [C
Transgranular corrosion fatigue crack growth in age-hardened Al-Zn-Mg (-Cu) alloys
Authors: Lynch Stan P. , Knop Mark , Byrnes Rohan T. 
Published: September 2015

Abstract
The mechanisms of transgranular corrosion fatigue in age-hardened Al-Zn-Mg (-Cu) alloys are reviewed, with an emphasis on accounting for fractographic observations. The effects of cycle frequency, solution composition, temperature, and electrode potential on crack-growth rates (and striation spacing and appearance) at intermediate to high ΔK are discussed in particular. It is concluded that corrosion fatigue, resulting in cleavage-like {100} <110> cracking with extensive slip on {111} planes intersecting crack fronts, can best be explained by an adsorption-induced dislocation emission mechanism (involving weakening of interatomic bonds at crack tips by adsorbed hydrogen). Solute hydrogen ahead of cracks appears to play little, if any, role in facilitating cleavage-like cracking, and the mechanisms based on decohesion are at odds with the locally high strains around cracks and the formation of nanovoids ahead of cracks.
