Intramuscular manifestation of non-hodgkin lymphoma and myeloma: Prevalence, clinical signs, and computed tomography features

Background: Intramuscular manifestations of malignant immunoproliferative diseases (IMMID) are very rare. Purpose: To determine the prevalence and the clinical features of IMMID in a large series of patients, and to analyze their radiological appearances. Material and Methods: Between 1997 and 2007, 20 patients with IMMID (non-Hodgkin lymphoma [NHL], n=14, and myeloma, n=6) were identified. All patients underwent computed tomography (CT). In five cases, magnetic resonance imaging (MRI) was additionally performed. Results: Clinically, 16 patients presented with local pain and soft-tissue swelling. In four patients, IMMID was found incidentally. The most common site was the erector spinae muscle, followed by the iliopsoas and pelvic muscles. In 13 cases of IMMID, diffuse mass-forming muscle infiltration was found. Focal intramuscular masses were identified in seven cases. Conclusion: NHL mostly manifests as diffuse muscle enlargement, whereas myelomas form focal intramuscular masses. Nevertheless, CT and MR appearances are nonspecific and can be misinterpreted as muscle sarcoma or inflammatory disease. Although rare, muscle involvement should be considered in the differential diagnosis of muscle disorders in patients with non-Hodgkin lymphoma and myeloma.
Alpha-thalassaemia and population health in Southeast Asia

Alpha-thalassaemia mutations are common. In Southeast Asia, they cause Hb H disease and Hb Barts hydrops fetalis. Fetuses with the devastating Hb Barts hydrops fetalis due to the complete lack of α-globin gene die in utero or shortly after birth, often during the second or third trimesters. Recent findings on patients with Hb H disease who have only one active α-globin gene suggest that it is not necessarily a benign disorder as previously thought. The disease burden of these syndromes and their public health importance have been largely neglected. We review the population carrier frequencies of α-thalassaemia, and summarize the clinical features, diagnostic approaches, counselling and management of these common genetic disorders. Several practical proposals are made that, if implemented, can begin to address the issues of collaboration and improvement for care of these common diseases in the region.
Compact eight-antenna array in the smartphone for the 3.5-GHz LTE 8 × 8 MIMO operation

A compact eight-antenna array in the smartphone for the 3.5-GHz band (3400 ∼ 3600 MHz) LTE 8 × 8 MIMO operation is presented. The eight-antenna array is formed by two quad-antenna arrays disposed along two long side edges of the system ground plane of the smartphone. The quad-antenna array occupies a small size of 1 × 60 mm2. For operating in an 8 × 8 MIMO system, the calculated channel capacity for the eight-antenna array can reach about 37 bps/Hz with 20-dB signal-to-noise ratio (SNR). Detailed results of the eight-antenna array and its MIMO performance are presented.
Self Amputation of Penis and Right Testis - A Case Report

Penile amputation is a rare urologic emergency but carries major functional and psychological consequences in regard to patient's overall quality of life. There is a paucity of case reports of traumatic penile amputation during circumcisions; however, most of the cases reported with self-mutilation are a result or severe substance-induced psychosis or underlying psychiatric disorder . We herein describe a case that resulted in a complete self-amputation of the patient's penis under the influence of alcohol and management methods when the amputated part of the penis is not available
Return to work after acquired brain injury: facilitators and hindrances observed in a sub-acute rehabilitation setting.

OBJECTIVES There is great variability in the rate of return to work for persons who have suffered from brain injury. The aims of this study was: 1) to describe employment status of persons with stroke or traumatic brain injury, one year after the incident and 2) to investigate the impact of injury/stroke severity, length of stay, the ability to perform activities of daily living and cognitive function on return to work. PARTICIPANTS AND METHODS Information was collected from 72 persons; 48 with a diagnosis of stroke and 24 with a traumatic brain injury. All patients had attended to a Rehabilitation Centre with inpatient and outpatient facilities. Data of the above mentioned variables was gathered retrospectively and information about employment status was retrieved from the medical records. RESULTS After one year, 13 persons (approximately 18%), 5 with a stroke and 8 with a traumatic brain injury (one with mild brain injury, 9 with moderate and 3 persons with severe injuries) had returned to work. They had significantly shorter length of stay at the rehabilitation hospital and were younger than those that did not return to work. Somewhat better results at the neuropsychological screening were seen among those that returned to work, although with a significant difference only in the subscale assessing affect. Some persons with severe injury returned to work, while a majority of those with mild brain injury did not. CONCLUSION Traumatic brain injury, younger age and less need of rehabilitation were associated with a higher rate of returning to work. Patients with stroke were older and seem to need more support in order to be successful in work return. It is of importance to reach primary rehabilitation goals, such as being ADL independent, as this was also favourable for work return. The impact of injury severity seemed complex and should to be further explored. Persons with mild brain injury should be followed-up with respect to work return. An important cognitive factor was ability to perceive and express affective responses, reflecting the need of social skills in today's work-life.
The Association of Salivary Calcium, Inorganic Phosphorus, Zinc and Copper in Children and Early Childhood Caries: A case-control study

Background Dental caries in children is the most common disease worldwide. It remains the most prevalent chronic disease in young children in some developing countries. Objectives This study was carried out to evaluate the levels of calcium (Ca), inorganic phosphorus (P), zinc (Zn) and copper (Cu) in the saliva of pre-school children aged 4-5 years and to evaluate their plausible association with Early Childhood Caries (ECC). Materials and Methods Sixty children were divided into two groups; thirty children with ECC and thirty children without dental caries experience. Two milliliters of unstimulated whole saliva were collected from each child using spitting method. The Atomic Absorption Spectrometer (AAP) was used to measure the levels of Ca, Zn, and Cu in saliva while Molybdenum Vanadate method was used to estimate the level of salivary P. Descriptive statistics, bivariate, and Pearson’s correlation analysis were done. Results Children with ECC demonstrated a higher Ca levels than caries-free children with a highly significant difference (P<0.001) whereas higher levels of P, Zn and Cu were found in caries-free children compared to children with ECC. A positive correlation to ECC was observed in salivary Ca while the correlation was negative in salivary P, Zn, and Cu. Conclusions Considerable variations in the levels of salivary elements between ECC and caries free children were noted. The correlation between salivary P, Zn, and Cu and ECC was negative and more studies are needed to determine the maximum efficacy of these elements in preventing ECC in children.
Effects of Supplemental Levels of Saccharomyces cerevisiae Fermentation Product on Lactation Performance in Dairy Cows under Heat Stress

The objectives of this study were to evaluate the effects of different supplemental levels of Saccharomyces cerevisiae fermentation product (SCFP; Original XP; Diamond V) on lactation performance in Holstein dairy cows under heat stress. Eighty-one multiparous Holstein dairy cows were divided into 27 blocks of 3 cows each based on milk yield (23.6±0.20 kg/d), parity (2.88±0.91) and day in milk (204±46 d). The cows were randomly assigned within blocks to one of three treatments: 0 (control), 120, or 240 g/d of SCFP mixed with 240, 120, or 0 g of corn meal, respectively. The experiment was carried out during the summer season of 2014, starting from 14 July 2014 and lasting for 9 weeks with the first week as adaption period. During the experimental period, average daily temperature-humidity index (measured at 08:00, 14:00, and 20:00) was above 68, indicating that cows were exposed to heat stress throughout the study. Rectal temperatures tended to decrease linearly (p = 0.07) for cows supplemented with SCFP compared to the control cows at 14:30, but were not different at 06:30 (p>0.10). Dry matter intake was not affected by SCFP supplementation (p>0.10). Milk yield increased linearly (p<0.05) with increasing levels of SCFP. Feed efficiency (milk yield/dry matter intake) was highest (p<0.05) for cows fed 240 g/d SCFP. Cows supplemented with SCFP gained (p<0.01) body weight, while cows in the control lost body weight. Net energy balance also increased linearly (p<0.01) with increasing levels of SCFP. Concentrations of milk urea nitrogen (p<0.01) decreased linearly with increasing levels of SCFP, while no difference (p>0.10) was observed among the treatments in conversion of dietary crude protein to milk protein yield. In summary, supplementation of SCFP alleviated the negative effect of heat stress in lactating Holstein dairy cows and allowed cows to maintain higher milk production, feed efficiency and net energy balance. Effects of SCFP were dose-dependent and greater effects were observed from higher doses.
Trade Unions and the Effectiveness of Worker Representation in Health and Safety in Britain

A feature of British legislation on employee representation in health and safety is its restriction to recognized trade unions. This has made British provisions unique within the European Union. New legislative provisions are under consultation and are likely to widen the existing Safety Representatives and Safety Committees Regulations. The approach of the proposed regulations raises a number of questions about the determinants of effectiveness of worker representation in health and safety that are discussed in this article. The significance of trade union support for representation in health and safety is shown to play an important role in determining the effectiveness of health and safety representatives, both through the role of trade unions within the workplace and through their ability to provide support for representation through training and information. Trends in national economies and employment patterns in Europe mean that trade unions' influence is diminishing, but their supportive role in health and safety representation has not been replaced by any alternative form of employee organization. The proposed new British Regulations are discussed in the light of these observations.
An intelligent support system for teaching three or more degrees-of-freedom robotic manipulator

In this paper, we propose a smart teaching system for many complex tasks achieved by a seven degrees-of-freedom robotic manipulator. In this system, we basically use a sliced 2-D configuration plane because of no occlusion. In general, an enormous number of such planes exist in seven dimensional configuration space. To select some fruitful planes from all the planes, we develop a human support system based on efficient path finding and obstacle evaluating algorithms in each 2-D plane. The efficiency of this human computer cooperation system is compared with that of the model-based path-planning algorithm A*. Selecting a near-optimal path in our system is absolutely faster than calculating its optimal path by A*. This means that a human ability understanding a task is quite powerful especially for a seven-degrees-of-freedom robotic manipulator.
Current status of brucellosis in dairy cows of Chiang Rai province, Thailand

Current status of brucellosis in dairy cows have an impact on livestock development in Chiang Rai due to transmission and creating infertile cows. Livestock development particularly in dairy cows have been hampered by low production including milk and meat production due to many pathogens including Brucella abortus, a gram negative bacteria, is the causative agent of brucellosis recognized as a major cause of bovine abortion around the world and known to have a detrimental effect on bovine pregnancy outcome and on milk production. Currently, there is no effective method for control of brucellosis. The objective of this study was to investigate the seroprevalence of brucellosis in dairy cows in Chiang Rai, Thailand. From January to June in 2007, the sera of 392 cows in 29 small holder farms from Chiang Rai were collected. Antibodies to B. abortus were determined by c-ELISA (SVANOVIR, Sweden) and 13 (3.3 %) samples were revealed seropositive. Cows between age of 1 and 5 years had the highest seroprevalence (3.8%) compared to cows with more than 5 years (2.8%). Phan district was the highest endemic area for B. abortus infections in dairy cows (60%). A total of dairy farm infections was 24.1% (7/29). The prevalence of individual B. abortus infections on cows was not high but the number of positive farms were rising. This result indicated the factor associated with dairy cow’s infertility in dairy farms. This will be beneficial for control strategy of brucellosis such food safety program of food animals in Chiang Rai.
INHIBITORY EFFECT OF SODIUM BICARBONATE AND SODIUM CARBONATE ON SPORE GERMINATION OF BACILLUS SUBTILIS

phates. In this work, to adjust pH of media, sodium bicarbonate was used. Since then it has been noticed that this substance and also sodium carbonate have a marked inhibitory effect on spore germination of B. subtilis. The results are shown in tables 1 and 2. From these it is obvious that sodium bicarbonate and sodium carbonate inhibit germination. In this case, it may be possible to say that HCO3 and CO3 act
Theoretical studies of atomic emission and defect formation by electronic excitation at the (100) surface of NaCl.

The F and H centers and self-trapped excitons near the (100) surface of NaCl have been simulated using the embedded-cluster Hartree-Fock calculation technique. An F center in the ground state in the top surface layer is shown to be stable. The activation energy of 1.94 eV is needed to emit a neighboring Na atom, while a Na atom can be emitted spontaneously when an F center is excited to the lowest excited state. The H center in the first two surface layers is found to be decomposed into a Cl- ion on the lattice site and a Cl0 atom physisorbed on an anion with a binding energy of 0. 14 eV. The H center located below the third layer is stable. The self-trapped exciton in the top and second layers is found to be unstable and decomposes into an F center and a Cl0 atom in the vacuum, while that below the third layer is relaxed similarly to those in the bulk. Existing experimental results on photoinduced emission of alkali and halogen atoms are discussed based on the results of calculations.
The incidence of venous thromboembolism following total knee arthroplasty: a prospective study by using computed tomographic pulmonary angiography in combination with bilateral lower limb venography

Venous thromboembolism (VTE), presenting as deep vein thrombosis (DVT) and pulmonary embolism, is one of the major complications following total knee arthroplasty (TKA). We conducted this prospective observational study to identify the prevalence of VTE among patients undergoing TKA by using computed tomographic pulmonary angiography in combination with bilateral lower limb venography. We enrolled consecutive patients admitted to our institution for primary unilateral TKA from September 2013 to July 2014. All participants underwent a standard surgical procedure of TKA. Computed tomographic pulmonary angiography and bilateral lower limb venography were performed within a week after the operation. We compared age, sex, BMI, comorbidities, data of laboratory tests, operation time and thromboprophylaxis between VTE group and non-VTE group to identify the risk factors. A total of 109 patients were enrolled in this study. The incidence of symptomatic DVT, asymptomatic DVT, symptomatic pulmonary embolism and asymptomatic pulmonary embolism following TKA was 4.6, 18.3, 1.8 and 1.8%, respectively. Elevated level of D-dimer was significantly associated with postoperative VTE. The incidence of VTE following TKA was high despite thromboprophylaxis, and asymptomatic DVTs accounted for a large proportion of thrombotic events.
Effect of Helicobacter pylori Infection on the Activity of Class I, III and IV Alcohol Dehydrogenase in the Human Stomach

Background/Aims: In the human stomach various alcohol dehydrogenase (ADH) isoenzymes exist. The gastric ADH activity is affected by a number of factors including also the infection of Helicobacterpylori. The objective was to investigate the activity of alcohol dehydrogenaseisoenzymes of class I, III and IV in endoscopic specimens of gastric mucosa from the different parts of the stomach of men and women, considering the H. pylori infection. Method: Biopsy samples of gastric mucosa were taken from the corpus and antrum of 68 patients (42 of men and 26 of women) suspected for gastric ulcer. The colonization of H. pylori was present in 22 samples of men and 13 samples of women. The activity of class I isoenzyme was measured by the fluorimetric method with a specific substrate (4-methoxy-1-naphthaldehyde) and the activity of class III and IV by the photometric method with n-octanol and m-nitrobenzaldehyde as a substrates, respectively. Results: In infected samples from the antrum and corpus of men’s and women’s stomachs the activity of class IV isoenzyme was decreased as compared to non-infected specimens. The activity of class III isoenzyme was decreased in the infected samples from the corpus of male patients, but the activity of class I does not significantly differ between infected and noninfected specimens from both sexes. Conclusion:H. pylori infection leads to significant decrease in the activity of class IV ADH in the stomach of men and women.
Online Identification of Power System Dynamic Signature Using PMU Measurements and Data Mining

This paper proposes a two-stage methodology for online identification of power system dynamic signature using phasor measurement unit (PMU) measurements and data mining. Only transient stability status is usually predicted in the literature to assist with corrective control, without the dynamic behavior of generators in the event of instability. This paper uses traditional binary classification to identify transient stability in the first stage, and then develops a novel methodology to predict the nature of unstable dynamic behavior in the second stage. The method firstly applies hierarchical clustering to define patterns of unstable dynamic behavior of generators, and then applies different multiclass classification techniques, including decision tree, ensemble decision tree and multiclass support vector machine to identify characterized unstable responses. The proposed methodology is demonstrated on a multi-area transmission test system. High prediction accuracy at both stages of identification is demonstrated.

Guideline Watch (August 2012): Practice Guideline for the Treatment of Patients With Eating Disorders, 3rd Edition

This guideline watch reviews new evidence and highlights salient developments since the 2006 publication of APA’s Practice Guideline for the Treatment of Patients With Eating Disorders, 3rd Edition. The authors of this watch constituted the work group that developed the 2006 guideline. We find the guideline to remain substantially correct and current in its recommendations. The sole exception is a recommendation (with moderate-level confidence) for sibutramine for binge-eating disorder. In 2010, the U.S. Food and Drug Administration (FDA) withdrew approval for sibutramine because clinical trials showed increased risk of heart attack and stroke, and the manufacturer, Abbott Laboratories, subsequently withdrew this medication from the U.S. market. Noteworthy recent publications about the treatment of eating disorders include systematic reviews by the Agency for Healthcare Research and Quality (Berkman et al. 2006; Bulik et al. 2007); practice guidelines from international groups, including the Catalan Agency for Health Information, Assessment and Quality (Working Group of the Clinical Practice Guideline for Eating Disorders 2009), the World Federation of Societies of Biological Psychiatry (Aigner et al. 2011), and the German Society of Psychosomatic Medicine and Psychotherapy and the German College for Psychosomatic Medicine (Herpertz et al. 2011); and a 2011 guidance statement by the Academy for Eating Disorders, which was written by some of the authors of this
The occurrence and nature of electrochemical activity in milk from a herd of dairy cows

Amperometric sensors may be used in milk analysis but electrochemical interference from compounds other than the analyte is an on-going problem. A survey was made of the level of electrochemical activity (potential interference) in milk from a herd of dairy cows grazing on summer pasture. It was a ubiquitous feature of the aqueous phase of whey and de-proteinized milk over about 3 months. The nature of the interference was studied by differential pulse voltammetry and responses to ascorbic acid oxidase and uricase. The principal source of interference appeared to be uric acid.
