Aim of the study was to examine sensitivity of preputial and vaginal exfoliative cytological examination as a noninvasive alternative to lymph node, spleen and bone marrow cytology, for detection of Leishmania infantum amastigotes in dogs with leishmaniosis, as, in previous studies, the protozoa have been observed in the penis and prepuce of male dogs and in the vagina of female dogs with leishmaniosis. In total, 20 male  and 18 female dogs with confirmed leishmaniosis were included inthe study. Three cytology smears were prepared from different sites of the preputial cavity of males and one smear was prepared from the anterior vagina of females. Leishmania amastigotes were not observed in these samples after microscopic examination for 20 min at 1,000× magnification. Therefore, preputial and vaginal exfoliative cytology is not recommended for routine diagnosis of canine leishmaniosis.
Ovine small bowel “minute rhythm” intensity related to feeding and phase of migrating myoelectric complex
Authors: ROMAŃSKI K. W.
Published: February 2018

The presented study was performed to characterize further the ‘minute rhythm’ in the ovine small bowel, notably to assess the role of fasting and feeding as well as of the phase of the MMC upon the number and amplitude of the MR-containing spike bursts. In eight rams the electrodes were attached to the pyloric antrum, duodenal bulb, duodenum and upper jejunum. In the course of chronic experiments, the myoelectrical recordings were conducted in fasted and non-fasted rams, before and after feeding offered during phase 2a or 2b of the MMC. The phases of the MMC and the MR episodes were identified and the MR frequency, the number of the spike bursts in one MR episode and their amplitudes were calculated. 74 per cent of the MR episodes exhibited the propagated character. At the beginning of phase 2a, the MR often arrived exclusively in the duodenal bulb and was disorganized, while at the end of phase 2b of the MMC, the MR-related spike bursts were most prominent and propulsive. In the duodenal bulb, the giant-like spike bursts forming the pattern were observed occasionally. The MR episodes contained usually 1-2 spike bursts. The number of the MR episodes, each containing one spike burst was smaller after feeding mostly in the duodenum and jejunum and it was lower during phase 2b than during phase 2a of the MMC in the duodenal bulb, duodenum and jejunum. The number of the spike bursts in one MR episode increased after feeding and during phase 2b of the migrating myoelectric complex and it was the highest in the jejunum. The spike burst amplitudes of the MR episodes were the highest in the duodenal bulb. Feeding during phase 2b of the MMC decreased the amplitude of the MR-related spike bursts both in the duodenum and the jejunum. It is concluded that the intensity of the MR in the ovine small bowel is related to feeding and to the phase of the MMC and the high variability of the pattern comprises its character and strength that are apparently related to the intraluminal influences affecting the controlling mechanisms.

Aim of this study was to investigate presence of Besnoitia besnoiti infection in indigenous and imported cattle in Greece. A total of 450 bovine blood sera samples from 15 dairy herds of Northern Greece were tested using a commercially available kit to detect specific anti-B. besnoiti antibodies. Ninety-eight cows were found to be seropositive to B. besnoiti (22%). Seropositivity varied among herds from 0% to 35%. Results were analysed using a univariate analysis of variance. A full factorial model was developed, using as independent variables area of sampling (Thrace, Macedonia) and origin of cattle (local, imported). No significant effect was found of the variables included into the model (P > 0.05). It is concluded that seropositive dairy cows are present in Northern Greece; however, impact of this parasite on animal production in Greece remains a key topic for further investigation.
The diagnostic significance of cardiac biomarkers in veterinary medicine
Authors: POLIZOPOULOU (Ζ.Σ. ΠΟΛΥΖΟΠΟΥΛΟΥ) Z. S.
Published: February 2018

Cardiac biomarkers are a group of proteins that have been extensively studied in human and veterinary medicine during the past decades, regarding their diagnostic and prognostic importance in heart disease. Moreover, cardiac biomarkers have been evaluated for their efficacy in the assessment of clinical staging of heart disease, risk stratification of patients, selection of therapeutic regimens and prognosis of cases. Cardiac biomarkers are broadly classified, according to their role in the pathophysiology of heart failure, into markers of myocardial injury (cardiac troponins, creatine kinase MB isoenzyme), myocyte stress (natriuretic peptides), inflammation (acute phase proteins), cardiac remodelling (matrix metalloproteinases), neurohormonal and endothelial dysfunction (endothelin, aldosterone, rennin, norepinephrine). It is unlikely that all of the aforementioned biomarkers will eventually be applied in clinical practice. Nevertheless, some of them (cardiac troponins, natriuretic peptides) have already been available commercially and established as part of the diagnostic investigation in heart disease. This review article focuses on the role of both established and potential cardiac biomarkers in veterinary medicine.

The aim of the present study was to report detection of Nocardia sp. from cutaneous lesions of sheep. Abscess material was collected from submandibular and parotid lesions in sheep for identification of Nocardia sp., which is well known as a causative agent for cutaneous or subcutaneous abscesses, disseminated disease, mastitis, and pneumonia. Nocardia sp. are Gram-positive, delicate, non-motile, branching filamentous bacteria that found in soil, dust, organic materials, water and aquatic environmental. Nocardia species generally yield a large variety of diseases in both normal and immunocompromised humans and animals. In the present study, bacterial staining methods and biochemical identification methods were applied for identification of Nocardia sp. in four sheep in Aydin. All cases had superficial abscesses in the submandibular and parotid region, mostly invading the head and neck regions. Neutrophilic leukocytosis was evident in three out of four sheep, and there was evidence of moderate anemia in two of the sheep. Samples were stained with Gram and modified Ziehl-Neelsen staining and streaked onto sheep blood agar, incubated at 37°C for 48-72 hours under aerobic condition, Sabouraud Dextrose Agar, incubated for one week under aerobic condition. Nocardia sp. was isolated from based on bacteriological investigation confirming numerous thin, Gram-positive, filamentous and nonacid fast organisms, and biochemical tests. Nocardia sp. strains were confirmed with 16s Rrna PCR method. Based on clinical appearance, hematological findings, and molecular analysis a definitive diagnosis cutaneousNocardiosis was made in the sheep. Initial therapy involving danofloxacin, with regard to antibiogram, for 10 days and local iodine solutions, resulted in clinical recovery on 35-45 days post-treatment. This is the first reported case of cutaneous Nocardiosis and its effective danofloxacin therapy in sheep in Turkey.

The effect of short-term instead of long-term progestagen treatment on fertility of Karagouniko and Chios ewes, after natural mating or artificial insemination, was investigated. Two experiments were performed during the transition period from anοestrous to the breeding season. In the 1st experiment (natural mating, NM), Karagouniko and Chios ewes were randomly allocated into 3 groups, that were KLM (long-term progestagen treatment; n=35), KSM (short-term progestagen treatment; n=34), KSP (short-term progestagen treatment; prostaglandin; n=35) and CLM (n=40), CSM (n=35), CSP (n=38), respectively. In the 2nd experiment (intracervical artificial insemination, AI) Karagouniko and Chios ewes were randomly allocated into 3 groups, that were KLA (long-term progestagen treatment; AI at 54h; n=50), KSA1 (short-term progestagen treatment; AI at 54h; n=20), KSA2 (short-term progestagen treatment; AI at 48h; n=28) and CLA (n=40), CSA1 (n=16), CSA2 (n=20), respectively. At sponges’ removal (d0) all ewes received 400 IU eCG. Ten rams served NM, while for AI fresh diluted semen was used. Pregnancy diagnosis was performed, 45-50 days later. Ιn the 1st experiment, blood samples were collected, daily for 5 days, starting on d0, for serum progesterone assessment. Conception rate in Karagouniko ewes after NM was higher (P<0.05) in KSM (35.29%) compared to KLM (17.14%) group, but did not differ with KSP (28.57%) group, while after AI it was higher (P<0.05) in KLA (42.00%) or KSA1 (40.00%) compared to KSA2 (14.29%) group. In Chios ewes no significant differences were observed between groups either after NM [CLM (45.00%), CSM (36.84%), CSP (34.29%)] or after AI [CSA1 (50.00%), CSA2 (50.00%), CLA (45.00%)]. No significant differences were observed after NM or after AI in the litter size in both breeds. These results indicate that short-term progestagen treatment for oestrus synchronization could be applied in indigenous Greek sheep breeds, resulting in equal (Chios) or improved fertility (Karagouniko) than the common long-term one. Also, the fertility rate in ewes subjected to short-term progestagen treatment depends on the time of AI in relation to breed.

Analgesia of laboratory animals consists an important component in experimental studies where painful stimuli or procedures may take place. When choosing analgesics, the severity of pain along with the response to medication is among the factors that determine the choice of agent. Tramadol is a known synthetic opioid analgesic used to treat main acute or chronic pain including perioperative pain. The purpose of this study was to evaluate the analgesic response as well as the effect on locomotor activity in two different strains of mice after the intraperitoneal (i.p.) administration of tramadol. Subjects were 11-13 week-old male C57BL/6J (n=39) and BALB/cJ (n=38) mice, randomly assigned to receive either saline, tramadol 10 mg/kg or tramadol 40 mg/kg. Analgesia was measured using the hot-plate test, 30 or 60 minutes after drug administration while the open field test was used in order to assess locomotor activity. Both strains exhibited a significant increase of hot-plate latencies after administration of tramadol 40 mg/kg while the same dose induced significantly greater analgesia in BALB/cJ as compared with the C57BL/6J mice. BALB/cJ mice presented a dose-dependent decrease in locomotor activity following tramadol administration whereas C57BL/6J mice receiving 40 mg/kg tramadol showed hyperactivity. In conclusion, the lower dose of tramadol (10 mg/kg) has insufficient antinociceptive effects on acute thermal pain for both strains. The highest dose of tramadol used in this study (40 mg/kg) was greater than the one required for BALB/cJ mice, as they were under sedation for at least 60 minutes after drug administration. The same dose of tramadol appeared to be effective on C57BL/6J tramamice as latency times on the hot plate were significantly increased. Despite this fact, it is not a suitable choice as an analgesic, especially postoperatively, as it causes hyperactivity to this strain. Special concern should be given to the fact that tramadol’s analgesic and behavioral effects depend not only on its dosage, but also on the strain in which it is administered.
The effect of vitamin E on mast cells in small intestine of broilers under heat stress
Authors: YILDIZ M. , KUM S. , EREN U.
Published: February 2018

The aim of this study is to identify the effect of vitamin E (DL-α-tocopherol acetate) (300 IU/kg) on mast cells in the small intestine (duodenum, jejunum and ileum) under heat stress. In the study, 42 one-day-old Ross 308 male broiler chicks were used. The chicks were randomly separated into 3 groups as follows; control (22±2°C), heat stress (35°C, 5 hours/per day) and vitamin E (300 IU/kg/per day) + heat stress (35°C, 5 hours/per day). The applications of heat stress and vitamin E began on the fifteenth day and ended on the thirty-fifth day. Tissue samples were taken from animals in each group of four and five-week-old chickens. Tissue samples were fixed in BLA (Basic Lead Acetate) solution. The sections were stained with toluidine blue (TB) (pH 0.5) and alcian blue-critical electrolyte concentration (AB-CEC) (pH 5.8, 0.3 M MgCl2) / Safranin O (SO) (pH 1.0) combined method. It was determined that increasing of the exposure duration to heat stress increased the number of mast cells in the small intestine of the boilers. Also, it was revealed that vitamin E reduced mast cell population under heat stress. Consequently, heat stress may play a role in the pathogenesis of small intestine-associated with disorders and the supplementation of vitamin E can contribute to regulate small intestine functions of broilers by decreasing mast cell proliferation and activation under heat stress.

Secondary feeding with commercial lipids enrichments such as the microencapsulated diets Diet A (33.42±3.00%) and Diet B (55.88±3.5%) compared with the marine yeast type product Diet C(8.59±1.0%) as a method of increasing the total lipids and ω-3 PUFA content of rotifers, hence enhancing their nutritional value as live feed prey for fish larvae in hatcheries. The total lipids the rotifers was affected analogous to the levels of these components in the feeds showing its maximum percentage uptake within 4 hours from the enrichment (20.27±3.52, 26.64±3.91, 11.31±2.30 respectively). There was not any significant toxicity to the animals due to the diets during the 16 hours experiment. The DHA/EPA for Diet A(1.31), Diet B(0.42) and Diet C(absent) as well as the DHA/EPA/ARA ratios for Diet A(10.70 ± 1.60 / 8.18 ± 1.10 / 2.08 ± 0.20), Diet B(6.20 ± 2.30 / 14.60 ±1.00 / 1.12 ± 0.40) and Diet C (0 / 5.14 ± 3.40 / 1.30 ± 1.10) indicates that Diet A is closer to the suggested DHA/EPA/ARA optimal value 10/5/1 for marine fish larval growth.

Published: February 2018

The present study investigated the effects of attapulgite supplementation in sow diets during gestation and lactation on sow performance. The study comprised two reproductive phases (cycles) in two commercial farrow to finish farms: Farm A (capacity: 550 sows) and Farm B (capacity: 220 sows). The treatment groups were: a) control group (CN): the sows were fed a common gestation or lactation diet; b) attapulgite group (AT): the sows were fed the CN diet supplemented with attapulgite at 0,7% level; c) attapulgite plus group (AT+): the sows were fed the CN diet supplemented with attapulgite (0.7%) and a mix of enzymes, live yeast and amino acids (0.1%), at a total of 0.8% level. Within each cycle the sows included per treatment were: 24 for Farm A; 12 for Farm B. Initially data were analyzed per cycle and per each farm. Data from sows that completed both cycles within each farm, were analyzed by repeated measures analysis. Regarding sow parameters, sow body weight loss during lactation tended to be greater in AT sows compared to CN sows during cycle 1 in Farm B and was greater in AT and AT+ than CN sows in Farm A that completed both cycles (P=0.063 and P=0.023, respectively). A greater litter size 24h postpartum was observed in favour of AT compared to CN group during cycle 1 in Farm A and in sows that completed both cycles in Farm A (P=0.001 and P= 0.011, respectively). Litter size at weaning was greater in sows from the AT group than CN during cycle 1 and 2 in Farm A, in cycle 1 in Farm B and in sows that completed both cycles in Farm A (P=0.004, P=0.037, P=0.037, and P=0.022, respectively). Piglet weight at weaning and average daily gain during lactation were greater in AT group than CN and AT+ in sows that completed both cycles in Farm A (P=0.049 and P=0.040 respectively). Notable similar effects, although not statistically significant, were also observed in Farm B. This field study suggests that attapulgite supplementation in sow diets can improve performance indexes. Further research should investigate the underlying mechanisms involved.
Management of distal limb skin defects in dogs and cats

Published: February 2018

Skin defects on the lower limb are common and their management is usually challenging. All trauma patients should be initially assessed for concurrent injuries and stabilized. Debridement and cleansing is performed in all wounds. The most important factors for decision making on wound closure are the wound size, the extent of soft tissue damage, the presence of contamination and impaired perfusion. Primary closure is the preferred choice although; it is seldom applicable in wounds on the distal limbs. Delayed primary closure, secondary closure or second intention healing can be undertaken under certain circumstances in such wounds. When these options are not feasible local pedicle flaps, axial pattern flaps, distant flaps, grafts, muscle or myocutaneous flaps and microvascular free tissue transfer can provide coverage.

Authors: CHANIOTAKIS I. , SPYRLIADIS A. , KATSIMPOULAS M. , KOSTOMITSOPOULOS N.
Published: February 2018

The mouse and the rat are currently overwhelmingly preferred as laboratory animals. Surgical research on animals requires anesthesia and analgesia to obtain adequate immobility and to reduce stress and pain. Small rodent anesthesia is challenging for several reasons including the animals’ size, metabolic rate, high risk of hypothermia and difficulty in monitoring. The purpose of this study is to create an overview of the information in the anesthetic practices for small rodents, in particular mice and rats.

Published: February 2018

Post mortem inspection records of poultry carcasses at 11 abattoirs in West Azerbaijan province, from March 20, 2008 to March 20, 2015 were used to investigate the prevalence of poultry condemnation. The daily condemnation records were used as the sources of data. In this study 171,297,886 poultry were slaughtered and 1,580,570 (0.92 %) poultry carcasses were condemned. Septicemia (25.7%) and Cachexia (34.6%) were the most common reasons for the condemnation and included 60.3% of the total condemnation. The financial loss as a result of the condemnation of poultry carcasses was estimated as high as 3,731,905 USD within the present study. If the local producers get acquainted with these facts and via extension educational programs the carcass condemnation and economical losses in industrial slaughterhouses could be reduced.

Cortisol is the most common physiological parameter used to measure welfare in pigs. In field studies evaluating stress in individual pigs which are group housed, the collection of spontaneously voided urine is practical. The purpose of the study was to apply a liquid chromatography coupled to high-resolution mass spectrometry approach to observe the patterns of diurnal urinary cortisol excretion among loose sows of three herds. We applied the analytical method in spontaneously voided urine of thirty, repeatedly sampled within a day, multiparous sows of three Greek herds. We found the level of urinary cortisol being highest before morning feeding [geometric mean of urinary cortisol to creatinine ratio being 2.72 (95% confidence interval: 1.17, 6.30), 5.65 (3.15, 10.14) and 2.60 (1.50, 4.50) in sows of herds A, B, and C, respectively] and lowest at 19:00 h [0.56 (0.27, 1.18), 1.24 (0.74, 2.07), 0.88 (0.55, 1.44)]. However, the patterns of diurnal urinary cortisol excretion appeared different among herds.
The official veterinarian and his role in the supervision of experiments on animals in the Polish legislation
Authors: FELSMANN M. Z. , SZAREK J. , SZYNAKA B.
Published: February 2018

Polish legislation regulating the supervision of animals used for scientific purposes has undergone significant changes in the last several years. The most important achievement was delegating the supervision of laboratory animal breeding, supply and experiments to veterinarians employed by the Veterinary Inspectorate. Initially, pursuant to the first regulations dating back to 1928, veterinarians were not assigned any role in the supervision of animals used for scientific purposes. Minor modifications in this respect were introduced in 1960. The first supervisory powers were introduced by the Act of 1997 involving approvals to be issued by veterinarians in compliance with the legal requirements of entities carrying out experiments on animals and entities breeding laboratory animals. The Act of 2005 on experiments on animals did not bring about significant changes in the powers of veterinarians supervising animals used for scientific purposes. The above-mentioned legal acts did not provide the Veterinary Inspectorate with greater rights to supervise animals used for scientific purposes. When the Act on Freedom of Economic Activity was amended (in 2007), the supervision of economic operators became particularly difficult or sometimes even impossible. The Act on the Protection of Animals Used for Scientific or Educational Purposes that was passed in Poland on 15 January 2015 is a legal act that delegates the right to comprehensive supervision of animals used for scientific purposes to one public authority, namely, the Veterinary Inspectorate.

Tendon injuries are considered major causes of wastage in active Thoroughbred racehorses as they are among the most common musculoskeletal injuries in equine athletes. There has been considerable interest in the potential use of concentrated adipose tissue digest, such as stromal vascular fraction, in tendon overstrain injuries. It has been reported that the adipose-derived stem cells, which are present in stromal vascular fraction of adipose tissue, can promote neovascularization and improve healing process. The purpose of this study was to evaluate the potential effects of intralesional use of autologous adipose-derived stromal vascular fraction on tendon healing in three Thoroughbred active racehorses with moderate to severe superficial digital flexor tendonitis. Based on the results of this report it seems that intratendinous injection of autologous adipose-derived stromal vascular fraction leads to marked clinical improvement and reduction of rehabilitation period in racehorses suffering from superficial digital flexor tendonitis.

Published: February 2018

Cryopreservation negatively affects equine sperm quality post-thaw: an excessive release of reactive oxygen species (ROS) and increased protein tyrosine phosphorylation (known as cryocapacitation) have been demonstrated in frozenthawed equine sperm diminishing its lifespan. The objective of this study was to determine the possible beneficial effect of genistein addition (a ROS scavenger and protein tyrosine kinase inhibitor) to a commercial freezing extender. Equine sperm were frozen in the presence of different genistein concentrations ranging from 0 to 800 μM. After thawing, the sperm viability (eosinnigrosin), acrosome integrity using peanut agglutinin (PNA), protein tyrosine phosphorylation (PY) and motility were assessed at times 0 and 1 hr. In addition PY was studied in fresh and frozen sperm incubated in Modified Whitten’s (MW) medium with 25 mM Bicarbonate (MW+Bic). Genistein did not affect the viability, total or progressive motility or acrosome status of frozenthawed equine sperm. Immediately after thawing, positive PY staining in the equatorial band was observed and genistein addition did not exert any change in PY. Fresh sperm incubated in MW+Bic showed a significant increase in PY staining along the tail compared to frozen-thawed sperm. In our study sperm viability immediately post-thaw was 58.25% ± 5.35 and progressive motility 14.46% ± 5.7 (mean ± S.E.M.) and genistein did not improve the post-thaw quality of equine sperm. In addition, cryopreservation did not induce PY immediately post-thaw or enhanced frozen-thawed equine sperm susceptibility to PY induction.

Published: February 2018

Aims

The aim of this study was to evaluate the long-term inducible displacement of cemented tibial components ten years after total knee arthroplasty (TKA).

Patients and Methods

A total of 15 patients from a previously reported prospective trial of fixation using radiostereometric analysis (RSA) were examined at a mean of 11 years (10 to 11) postoperatively. Longitudinal supine RSA examinations were acquired at one week, one year, and two years postoperatively and at final follow-up. Weight-bearing RSA examinations were also undertaken with the operated lower limb in neutral and in maximum internal rotation positions. Maximum total point motion (MTPM) was calculated for the longitudinal and inducible displacement examinations (supine versus standing, standing versus internal rotation, and supine versus standing with internal rotation).

Results

All patients showed some inducible displacement. Two patients with radiolucent lines had greater mean standing-supine MTPM displacement (1.35; sd 0.38) compared with the remaining patients (0.68; sd 0.36). These two patients also had a greater mean longitudinal MTPM at ten years (0.64; sd 0.50) compared with the remaining patients (0.39; sd 0.13 mm).

Conclusion

Small inducible displacements in well-fixed cemented tibial components were seen ten years postoperatively, of a similar magnitude to that which has been reported for well-fixed components one to two years postoperatively. Greater displacements were found in components with radiolucent lines. Cite this article: Bone Joint J 2018;100-B:170–5.
Outcomes after extensive manual curettage and limited burring for atypical cartilaginous tumour of long bone
Authors: Kim W. , Lee J. S. , Chung H. W.
Published: February 2018

Aims

Adjuvant treatment after intralesional curettage for atypical cartilaginous tumours (ACTs) of long bones is widely accepted for extending surgical margins. However, evaluating the isolated effect of adjuvant treatment is difficult, and it is unclear whether not using such adjuvants provides poor oncological outcomes. Hence, we analyzed whether intralesional curettage without cryosurgery or chemical adjuvants provides poor oncological outcomes in patients with an ACT.

Patients and Methods

A total of 24 patients (nine men, 15 women) (mean age 45 years; 18 to 62) were treated for ACTs of long bones and followed up for a median of 66 months (interquartile range 50 to 84). All patients were treated with extensive manual curettage and limited burring. Bone cement and grafts were used to fill bone defects in 16 and eight patients, respectively. No chemical adjuvants or cryosurgery were used.

Results

No local recurrence was detectable on plain radiographs and MRI or CT images. At the last follow-up, there were no distant metastases or disease-specific deaths. No procedure-related complications or postoperative fractures developed.

Conclusion

Intralesional curettage without cryosurgery or chemical adjuvants may provide excellent oncological outcomes for patients with ACTs of long bones, without the risk of complications related to adjuvant use. Our investigation suggests thorough curettage alone is a reasonable treatment option for ACT. However, we acknowledge the limited size of our investigation warrants a multicentre collaborative study to confirm our findings. Cite this article: Bone Joint J 2018;100-B:256–61.
A new and reliable classification system for fractures of the navicular and associated injuries to the midfoot
Authors: Petrie M. J. , Blakey C. M. , Chadwick C. , Davies H. G. , Blundell C. M. , Davies M. B.
Published: February 2018

Aims

Fractures of the navicular can occur in isolation but, owing to the intimate anatomical and biomechanical relationships, are often associated with other injuries to the neighbouring bones and joints in the foot. As a result, they can lead to long-term morbidity and poor function. Our aim in this study was to identify patterns of injury in a new classification system of traumatic fractures of the navicular, with consideration being given to the commonly associated injuries to the midfoot.

Patients and Methods

We undertook a retrospective review of 285 consecutive patients presenting over an eight- year period with a fracture of the navicular. Five common patterns of injury were identified and classified according to the radiological features. Type 1 fractures are dorsal avulsion injuries related to the capsule of the talonavicular joint. Type 2 fractures are isolated avulsion injuries to the tuberosity of the navicular. Type 3 fractures are a variant of tarsometatarsal fracture/dislocations creating instability of the medial ray. Type 4 fractures involve the body of the navicular with no associated injury to the lateral column and type 5 fractures occur in conjunction with disruption of the midtarsal joint with crushing of the medial or lateral, or both, columns of the foot.

Results

In order to test the reliability and reproducibility of this new classification, a cohort of 30 patients with a fracture of the navicular were classified by six independent assessors at two separate times, six months apart. Interobserver reliability and intraobserver reproducibility both had substantial agreement, with kappa values of 0.80 and 0.72, respectively.

Conclusion

We propose a logical, all-inclusive, and mutually exclusive classification system for fractures of the navicular that gives associated injuries involving the lateral column due consideration. We have shown that this system is reliable and reproducible and have described the rationale for the subsequent treatment of each type. Cite this article: Bone Joint J 2018;100-B:176–82.

Authors: Bovonratwet P. , Malpani R. , Ottesen T. D. , Tyagi V. , Ondeck N. T. , Rubin L. E. , Grauer J. N.
Published: February 2018

Aims

The aim of this study was to compare the rate of perioperative complications following aseptic revision total hip arthroplasty (THA) in patients aged ≥ 80 years with that in those aged < 80 years, and to identify risk factors for the incidence of serious adverse events in those aged ≥ 80 years using a large validated national database.

Patients and Methods

Patients who underwent aseptic revision THA were identified in the 2005 to 2015 National Surgical Quality Improvement Program (NSQIP) database and stratified into two age groups: those aged < 80 years and those aged ≥ 80 years. Preoperative and procedural characteristics were compared. Multivariate regression analysis was used to compare the risk of postoperative complications and readmission. Risk factors for the development of a serious adverse event in those aged ≥ 80 years were characterized.

Results

The study included 7569 patients aged < 80 years and 1419 were aged ≥ 80 years. Multivariate analysis showed a higher risk of perioperative mortality, pneumonia, urinary tract infection and the requirement for a blood transfusion and an extended length of stay in those aged ≥ 80 years compared with those aged < 80 years. Independent risk factors for the development of a serious adverse event in those aged ≥ 80 years include an American Society of Anesthesiologists score of ≥ 3 and procedures performed under general anaesthesia.

Conclusion

Even after controlling for patient and procedural characteristics, aseptic revision THA is associated with greater risks in patients aged ≥ 80 years compared with younger patients. This is important for counselling and highlights the need for medical optimization in these vulnerable patients. Cite this article: Bone Joint J 2018;100-B:143–51.

The Present as History' and the Theory of Monopoly Capital
Authors: Foster John Bellamy , Konat Grzegorz
Published: February 2018

The most important principle of the monopoly capital tradition is that of "the present as history"—a focus on the historical specificity that separates the various modes, stages, and phases of production and accumulation, and its application to our understanding of the present.Click here to purchase a PDF version of this article at the Monthly Review website.
Economic History and the 'East Wind': Challenges to Eurocentrism
Authors: Schmidt Johannes Dragsbaek , Hersh Jacques
Published: February 2018

The decline of Western dominance over the capitalist world system and the concurrent rise of Asia demand a deconstruction of the accepted wisdom of economic history. Understanding the legacy of Eurocentrism in both the rise of capitalism and its historiography is necessary if we are to challenge the dominant discourse and ideological assumptions of the so-called "European miracle."Click here to purchase a PDF version of this article at the Monthly Review website.
An Empirical Study of Uniform and Differential Pricing in the Movie Theatrical Market
Authors: Ho Jason Y.C. , Liang Yitian (Sky) , Weinberg Charles B. , Yan Jing
Published: February 2018

Movies vary widely in appeal, star power, cost, and other elements, and therefore, each might be expected to charge a different price. Multiplexes, however, typically charge the same price for all movies, except for such premium formats as 3D, a choice that has puzzled managers and researchers. Because of data limitations, minimal empirical work has directly addressed this issue. In Hong Kong, however, prices vary both within and across multiplexes. Using daily ticket prices and attendance by theater and movie, the authors empirically examine the potential gains from differentiated movie-specific pricing as well as the increasingly common two-tier (2D/3D) uniform pricing, as compared with a full uniform pricing strategy in which a theater charges the same price for all its movies. Their results show that differential pricing leads to higher profits than the two-tier uniform pricing practice, but that the improvement is limited. In contrast, the gains are substantial when compared with the full uniform pricing strategy, suggesting that only minimal differentiation (2D/3D) may obtain most of the gains available from fully differentiated prices.
Mongol Imperialism in the Southeast: Uriyangqadai (1201–1272) and Aju (1127–1287)
Authors: Fiaschetti Francesca
Published: February 2018

Son of the famous general Sübe’edei, Uriyanqadai followed in his father’s footsteps into the highest ranks of the Mongol military. Placed in charge of the keshig, or imperial bodyguard, under Möngke (r. 1251–1259), his fame was mostly due to his involvement—along with prince Qubilai (r. 1260–1294)— in the Mongol campaigns in Tibet, Yunnan and Đại Việt. Some of these campaigns are thoroughly described in his Yuanshi and other biographies. Other sources reflect the political relevance of this general as well. The same goes for Uriyangqadai’s son Aju, who accompanied him on campaigns in the South and built upon Uriyangqadai’s legacy after his death. An analysis of the various texts reporting the careers of the two generals provides important material regarding a decisive moment in the Mongol conquest of China, as well as information on numerous aspects of the military and political structures of the Mongol empire. Uriyangqadai’s and Aju’s lives provide an important case study of the role of political alliances and family relations in the formation of the military elite under Mongol rule. Furthermore, their careers depict an important moment of change in Mongol warfare. The campaigns in Yunnan and Đại Việt proved a challenge to Mongol strategies, leading to important innovations, changes which ultimately facilitated creation of a Yuan land –and maritime Empire.
Prince Manggala – The Forgotten Prince of Anxi
Authors: Shurany Vered
Published: February 2018

Manggala (忙哥剌 d. 1278）was the third son of Qubilai Qa’an (r. 1260–1294) and his chief wife, Chabi Qatun (察必 d. 1281). Although he was not the crown prince he ruled over a large and strategic territory between the frontiers of the Southern Song before it was fully conquered, and the northwestern frontier, where some of the Mongol princes still challenged Qubilai’s legitimacy as the Great Khan. In spite of this, Prince Manggala does not have a biography in the Yuanshi, and is mainly remembered as the father of Prince Ananda, Qubilai’s grandson, famous for embracing Islam. However, juxtaposing sources from different parts of the Mongol empire to compile Prince Manggala’s biography shows that he appears to have been a governor and capable military commander, who established his own princely administrative system, Wangxiangfu (王相府), showed interest in both Islam and Buddhism and addressed the various peoples and religions in his heterogeneous domain differently, thereby enhancing his legitimation. Manggala’s annotated biography can expand our knowledge of the role and status of princes in the Yuan dynasty (元代 1271–1368), as well as shed light on both administration and cross-cultural contacts in northwest China during the early Yuan era.
Kingship away from Kingdom: The Life of King Ch’ungsŏn (1275–1325)
Authors: Soyoung Choi
Published: February 2018

King Ch’ungsŏn 忠宣, called Wang Chang 王璋, the 26th King of the Koryŏ Dynasty, was a unique figure among Korean kings. Born to King Ch’ungnyǒl and Qubilai Qa’an’s daughter, he also married a Mongol princess, thereby becoming an imperial son-in-law (güregen). During his first reign (1298), he made efforts to reform Koryŏ politics but several months later was deposed by the Mongols and moved to the Mongol capital Dadu 大都. In Dadu, King Ch’ungsŏn served in the royal guard (keshig) for 10 years. In the succession struggle that followed Temür Qa’an’s demise in 1307 he distinguished himself in the service of Qaishan (武宗) and Ayurbarwada (仁宗) and rose to power at the Mongol court, and in 1308 was restored to the Korean throne in Koryŏ. Just after the coronation he returned to Dadu and remained there despite Korean and Mongol appeals. When his long sojourn in Dadu provoked criticism, he abdicated for his son but continued to be involved in Korean affairs from his Dadu residence. However, after the death of Ayurbarwada, Wang Chang was banished to Sakya, Tibet, for reasons that are still debated. The new Qa’an Yesün Temür (泰定帝), pardoned him after more than two years in exile. However, even then, he did not return to Koryŏ but ended his life in the Mongol capital, Dadu. Wang Chang’s life demonstrates the complicated relationship between the Mongols and their vassal dynasties.
Crossing Language Borders – as Shown by the Historical Dictionary of the Hungarian Language in Transylvania
Authors: Zsemlyei Borbála
Published: February 2018

Transylvania has always been a space of multiculturalism, which is reflected in the fact that the Hungarian regional standard contains more Romanian and German elements than the central standard. And that is not only peculiar to the present state of the language, but it is a historical phenomenon. During the process of editing the Historical Dictionary of the Hungarian Language in Transylvania, Attila Szabó T. and his co-workers realized that the language material gathered from Transylvanian archives contains a number of Hungarian words of Romanian origin that the literature has no knowledge of. Thus came the idea of a smaller dictionary which would present the Romanian loan words of Hungarian spoken in Transylvania in the period of the 16th–19th centuries. By the mid-1980s, the editorial work was finalized; however, it has never been published – the material is kept at the Department of Hungarian and General Linguistics, Babeş–Bolyai University, Cluj-Napoca. In my paper, I will attempt to present the words of Romanian origin listed in the Historical Dictionary of the Hungarian Language in Transylvania, which the general literature of loan words has no knowledge of in the context of crossing borders, in the sense that neighbouring languages always have a huge impact on each other even if they are completely different genetically.
Culture in Language Teaching
Authors: Kovács Gabriella
Published: February 2018

Learning a language means also the study of a different culture. This study focuses on the introduction of the topic of culture in language teaching into the curriculum of the subjectLanguage Teaching Methodologyfor teacher trainees studying atTranslation And Interpreting Studies, Sapientia Hungarian University of Transylvania, Faculty of Technical and Human Sciences, Târgu-Mureş. This topic has not been treated separately so far, it has only been discussed implicitly, included in other topics. But we believe that future teachers should have a more thorough theoretical and practical training in terms of what incorporating culture into language teaching implies. For this purpose, we are going to examine and discuss some of the recommendations and principles stated in the specialized literature regarding culture in foreign language teaching and reflect on what the ideal content of a course related to the teaching of this skill should be.
Zu theoretischen und praktischen Aspekten des Fachübersetzens
Authors: Seidl-Péch Olívia
Published: February 2018

In the past few decades, it has extensively been written about corpus linguistics, which has owned its upswing mainly to the use of electronic corpora since the 1960s (Brown Corpus). Meanwhile, an increasing number of fields within general and applied linguistics (e.g. computational linguistics, discourse analysis, contrastive linguistics, diachronic and synchronic linguistics, language teaching and learning research, lexicology and lexicography, psycholinguistics, sociolinguistics, translation studies) have been using corpus linguistic methods. In linguistic research, the empirical and descriptive character of corpus-based linguistic analysis has also been given an emphasis.

Thanks to the digital revolution of the 20th and 21st centuries the creation and provision of digital linguistic corpora is becoming accessible for smaller nations and language communities as well as for scientists. Nowadays, linguistic corpora cannot only be regarded as a tool to support language research and Translation Studies, but they also contribute to the enrichment of cultural diversity. The article focuses on international examples as well as on the most significant Hungarian corpora. The paper also discusses the criteria of corpus creation and several cultural aspects of corpus linguistics.
