Distribution of milled carbon fibers as a function of their length on S-glass fabric and its effect on the electromagnetic properties of S-glass epoxy composites
Authors: Ivaturi Srikanth , Baske Himanshu , Ghosal Partha
Published: December 2018

Milled carbon fibers added S-glass epoxy composites were fabricated using milled carbon fibers as fillers. Milled carbon fibers having five different lengths namely 7, 20, 60, 200 and 400 µm were used to fabricate five different S-glass epoxy composites. Optical microscope and scanning electron microscope studies of S-glass epoxy composites indicated that milled carbon fibers having 400 µm length settled at weave openings as large clusters besides spreading on the tow surfaces at the interfilament undulations. Milled carbon fibers having 200 µm length were found to form smaller clusters at weave openings with an array of interconnected network in the resin-rich grid zones on the tow surfaces at the interfilament undulations. Milled carbon fibers having 60 µm and further lower lengths were found to get arrested at the interfilament undulations with random orientations without interconnectivity. Electromagnetic properties namely permittivity, loss tangent, and reflection loss of the fabricated composites measured in the range of 8 GHz to 18 GHz indicated that controlled agglomeration of the milled carbon fibers with interconnectivity is required for observing increase in the electromagnetic properties. This study indicated that S-glass epoxy composites added with milled carbon fibers having 400 µm length can show better conductivity due to increased interconnectivity but cannot effectively absorb incident microwave energy due to their inability to confine within the resin-rich grid zones as well as increased reflections from the large clusters that are formed at weave openings.
Self-inflicted bilateral ocular and eyelid injuries in an unsuspected individual
Authors: Samia-Aly Emma , Ha Jerome , Sagili Suresh
Published: December 2018

Background and aims

This report aims to illustrate a case of self-inflicted ocular and orbital injury, resulting in severe tissue loss and ophthalmoplegia in a patient with no known history of mental illness.

Methods and results

A 71-year-old male initially presented to the emergency department with significant tissue loss from his left upper and lower lids, orbital tissue loss and complete ophthalmoplegia, after reportedly tripping and falling onto his desk. He subsequently attended the emergency department on two further occasions with similar injuries, affecting the same and contralateral eye, whilst maintaining a traumatic cause for his injuries. He was eventually admitted to a psychiatric ward for mental health assessment. This report covers his progress as well as illustrating his injuries with images.

Conclusion

Self-harm is an important differential diagnosis in cases where the mechanism of injury does not correspond to the extent of injury or tissue loss. It can, however, be difficult to differentiate from accidental injury and even with repeated assessments, a formal psychiatric diagnosis may not be possible.
Suitability of lyocell fiber for pillow fillings
Authors: Cafuta Danijela , Abu-Rous Mohammad , Jary Susanne , Scheffelmeier Miriam , Rijavec Tatjana
Published: December 2018

The choice of a comfortable pillow is essential for good sleep. The filling material for pillows should be bulky, resilient and comfortable. For reasons of price, availability and resilience, polyester is the most commonly used filling material. Its drawbacks, however, lie in poor moisture management and a lack of biodegradability. This is the first study of the physical and microclimate properties of pillows with carded filling containing lyocell fiber. Pillow samples were manufactured on an industrial production line. Their carded fillings were rolled and comprised either 30% or 50% lyocell, blended with polyester (virgin and recycled), high elastic triexta and biodegradable polylactide fibers. In simulated sleeping conditions, using a thermal sweating manikin, it was proven that pillows with fillings made of 50% lyocell blended with polyester demonstrated an enhanced microclimate through much better moisture management than pillows with fillings made from pure polyester. It was also found, under use and care conditions, that lyocell affected the sensorial properties of pillows. Pillow form stability and height regain correlated with lyocell’s linear density. A higher lyocell content (50%) improved the form-keeping characteristics of pillows after repeated washing and drying. The type of lyocell used had only a minor effect on the compression resilience of the filling and perception of pillow firmness. The evaluators perceived higher pillows as firmer. The developed new methods for the evaluation of pillow quality and the results of this study can be of practical relevance in the bedding industry, where the reduction of non-biodegradable raw material is strategically important.
Relevance of flexibility versus radial force in rigid versus more flexible venous stents?
Authors: van Vuuren Timme MAJ , de Wolf Mark AF , Wittens Cees HA
Published: December 2018

Introduction

Deep venous stenting has gained increasing interest. More flexible venous stents are thought to gain superior clinical outcomes. This research evaluated the patency and clinical outcomes between more rigid stents and more flexible stents.

Material and methods

The Venous Clinical Severity Score, Villalta, complication rates and patency rates were evaluated. The more rigid stents included the Sinus XL, the Veniti VICI and the Sinus Obliquus. The flexible group included the Zilver Vena or the Sinus Venous stents.

Results

Differences in Venous Clinical Severity Score (p = 0.09) and Villalta score were found (p = 0.28). Tapering (0 versus 5, p = 0.03) and bad alignment were found (0 versus 5, p = 0.03). The rigid stents showed patency rates of 80, 86 and 92% compared to 88, 96 and 98% in the flexible group.

Conclusion

Dedicated venous stents show good patency outcomes and clinical results. Tapering and bad alignment between connecting stents are more frequently seen in more rigid stents.
Experimentally examining the mechanical behaviour of nap-core sandwich material – A novel type of structural composite
Authors: Ha Giap X , Bernaschek Andreas , Zehn Manfred W
Published: December 2018

Experimental investigation of the nap-core sandwich is presented in detail, in which the nap-core is based on knitted fabric, being impregnated with a thermoset resin, formed to create cup-shaped naps, and stabilized to assume a permanent 3D contour. The material is a novel type of lightweight sandwich-structured composite which has good specific strengths and possesses various properties crucial for engineering applications, but its exploitation is still restricted due to insufficient research and understanding. The sample preparation is first described, being followed by the test implementation and outcomes. The results obtained from typical tests demonstrate high performance of the nap-core sandwich samples under different cases of loading. They also reveal the sandwich’s essential behaviours which are similar to those of a common shell structure, giving it a great potential of being computationally modelled with finite element software.

Authors: Featherston Rebecca Jean , Shlonsky Aron , Lewis Courtney , Luong My-Linh , Downie Laura E. , Vogel Adam P. , Granger Catherine , Hamilton Bridget , Galvin Karyn
Published: December 2018

Purpose:

This systematic review synthesized evidence supporting interventions aimed at mitigating cognitive bias associated with the decision-making of social work professionals.

Methods:

A systematic search was conducted within 10 social services and health-care databases. Review authors independently screened studies in duplicate against prespecified inclusion criteria, and two review authors undertook data extraction and quality assessment.

Results:

Four relevant studies were identified. Because these studies were too heterogeneous to conduct meta-analyses, results are reported narratively. Three studies focused on diagnostic decisions within mental health and one considered family reunification decisions. Two strategies were reportedly effective in mitigating error: a nomogram tool and a specially designed online training course. One study assessing a consider-the-opposite approach reported no effect on decision outcomes.

Conclusions:

Cognitive bias can impact the accuracy of clinical reasoning. This review highlights the need for research into cognitive bias mitigation within the context of social work practice decision-making.
Ethnic reindeer herders: Groupness among reindeer-herding Sámi in Northwest Finnish Lapland
Authors: Nykänen Tapio , Valkeapää Leena
Published: December 2018

In the article, we examine the ethnic groupness among Sámi reindeer herders in Northwest Finnish Lapland. According to our results, reindeer herders recognize different groupnessess. Sáminess is perceived as an ethnic and often local, family-related groupness. Moreover, Sámi ethnicity is closely bound to the local herding life on the fells, in the cultural landscape of nomadism. Finnishness, on the other hand, involves meanings relating to the state and nation in particular. The interviews provide indications of the general rise of Sámi culture, the long-term influence of Finnish culture and the state and the multidimensional nature of ethnicities in everyday life, that is, an overlapping and richness of ethnicities and identifications.
Knockdown of TRPV2 channels in sensory neurons increases limb use and weight bearing but does not affect spontaneous flinching behavior in a mouse model of bone cancer

Published: December 2018

Bone cancer pain is a complex pain state involving ongoing pain and movement-related pain, which are thought to be caused by different mechanisms. Transient receptor potential vanilloid subfamily 1 (TRPV1) is involved in ongoing pain but not movement-related pain. The purpose of this study was to investigate the role of transient receptor potential vanilloid subfamily 2 (TRPV2) in bone cancer pain.

Proportions of TRPV1- and TRPV2-immunoreactive neurons in lumbar dorsal root ganglia innervating the femurs of male mice were examined by using Fluoro-Gold. Mice were intrathecally injected with small interfering RNA (siRNA) against TRPV2 or scrambled siRNA for three consecutive days from day 14 after sarcoma injection into the left femur. In the mice with bone cancer, the number of spontaneous flinches was quantified for assessment of ongoing pain, and limb use and weight bearing were assessed as indications of movement-related pain. Changes in TRPV2 protein levels in dorsal root ganglion were evaluated by Western blotting. We also examined the effects of intrathecal administration of siRNA against TRPV2 or scrambled siRNA on thermal and mechanical sensitivities in normal mice without tumors.

The proportions of TRPV1-immunoreactive and TRPV2-immunoreactive neurons were 21% and 22% of neurons in dorsal root ganglia innervating the femur, respectively. Tumor-bearing mice exhibited an increased number of spontaneous flinches and impaired limb use and weight bearing at day 13 after sarcoma injection. TRPV2 protein level in dorsal root ganglia at day 13 was comparable to that at baseline. siRNA against TRPV2 significantly improved limb use and weight bearing but did not affect the number of spontaneous flinches compared to those in the group treated with scrambled siRNA. siRNA against TRPV2 did not affect thermal or mechanical sensitivity in normal mice.

The results suggest that TRPV2 is involved in movement-related pain but not ongoing pain in mice with bone cancer.
Genetics of Human Primary Hypertension: Focus on Hormonal Mechanisms
Authors: Manosroi Worapaka , Williams Gordon H
Published: December 2018

Increasingly, primary hypertension is being considered a syndrome and not a disease, with the individual causes (diseases) having a common sign—an elevated blood pressure. To determine these causes, genetic tools are increasingly employed. This review identified 62 proposed genes. However, only 21 of them met our inclusion criteria: (i) primary hypertension, (ii) two or more supporting cohorts from different publications or within a single publication or one supporting cohort with a confirmatory genetically modified animal study, and (iii) 600 or more subjects in the primary cohort; when including our exclusion criteria: (i) meta-analyses or reviews, (ii) secondary and monogenic hypertension, (iii) only hypertensive complications, (iv) genes related to blood pressure but not hypertension per se, (v) nonsupporting studies more common than supporting ones, and (vi) studies that did not perform a Bonferroni or similar multiassessment correction. These 21 genes were organized in a four-tiered structure: distant phenotype (hypertension); intermediate phenotype [salt-sensitive (18) or salt-resistant (0)]; subintermediate phenotypes under salt-sensitive hypertension [normal renin (4), low renin (8), and unclassified renin (6)]; and proximate phenotypes (specific genetically driven hypertensive subgroup). Many proximate hypertensive phenotypes had a substantial endocrine component. In conclusion, primary hypertension is a syndrome; many proposed genes are likely to be false positives; and deep phenotyping will be required to determine the utility of genetics in the treatment of hypertension. However, to date, the positive genes are associated with nearly 50% of primary hypertensives, suggesting that in the near term precise, mechanistically driven treatment and prevention strategies for the specific primary hypertension subgroups are feasible.

Authors: Erwin Erwin , Pusparohmana Widar Ristiyani , Sari Indah Permata , Hairani Rita , Usman Usman
Published: December 2018

Background: Tampoi (Baccaurea macrocarpa) is a tropical rainforest plant that produces edible fruit and is native to Southeast Asia, especially East Kalimantan, Indonesia. Previous research showed that Tampoi potentially can be developed as a drug. It was reported that the extract of Tampoi fruit displayed antioxidant activity, which was correlated with its phenolic and flavonoid substances. There is no information about the antioxidant activity of other parts of this plant, such as the bark, which might also have this kind of activity. Therefore, the aim of this study was to evaluate the phytochemical, toxicity, and antioxidant activity of the bark of Tampoi.

Methods: The bark of Tampoi was extracted with methanol and concentrated using rotary evaporator to obtain the methanol extract of the bark. Secondary metabolites of this extract was determined using phytochemical analysis. Afterward, the methanol extract was tested for its toxicity using brine shrimp lethality test and antioxidant activity using the 2,2-diphenyl-1-picrylhydrazyl method.

Results: Phytochemical evaluation results showed that the methanol extract of bark of this plant contains several secondary metabolites including alkaloids, flavonoids, phenolics, steroids, and triterpenoids. The toxicity test displayed no toxic property due to a LC50 value above 1000 ppm. For antioxidant activity, the result exhibited that the methanol extract of bark of this plant could be categorized as an active extract with IC50 value of 11.15 ppm. Moreover, based on gas chromatography-mass spectrometer analysis, there are 37 isolated compounds from the bark, one of which is methylparaben, a phenolic predicted to act as an antioxidant.

Conclusion: The results obtained in this research demonstrated that the bark of Tampoi (B. macrocarpa) has potential as an antioxidant.

In this sophisticated era, teenagers tend to close to technology for their communication. One of the communication technology they use is LINE. Beside for communication, LINE also has several services for entertainment, and one of them is webtoon. Webtoon provides online comics to be enjoyed by everyone. Webtoon is an application from Korea which spreads around the world and each country can create domestic comics to be published in webtoon. In Indonesia, webtoon is more and more popular, especially for young generation. It published many comics, either in Indonesian language or mixed with regional languages. Some comics are created in mixed Indonesian and Javanese language, for example Jamu Mbok De. The use of Javanese in that comic helps a lot in the Javanese maintenance. By reading that comic, the Javanese young generation becomes more familiar with Javanese. In which nowadays, they prefer to use Indonesian rather than Javanese because of the environment. Therefore, there are less and less effort to maintain the Javanese language which impacts to Javanese daily usage. By publishing comics in Webtoon using mixed Indonesian and Javanese, it can be one of the way to maintain the regional language.

Children in US military families share common experiences and unique challenges, including parental deployment and frequent relocation. Although some of the stressors of military life have been associated with higher rates of mental health disorders and increased health care use among family members, there are various factors and interventions that have been found to promote resilience. Military children often live on or near military installations, where they may attend Department of Defense–sponsored child care programs and schools and receive medical care through military treatment facilities. However, many families live in remote communities without access to these services. Because of this wide geographic distribution, military children are cared for in both military and civilian medical practices. This clinical report provides a background to military culture and offers practical guidance to assist civilian and military pediatricians caring for military children.

Published: December 2018

Infantile hemangiomas (IHs) occur in as many as 5% of infants, making them the most common benign tumor of infancy. Most IHs are small, innocuous, self-resolving, and require no treatment. However, because of their size or location, a significant minority of IHs are potentially problematic. These include IHs that may cause permanent scarring and disfigurement (eg, facial IHs), hepatic or airway IHs, and IHs with the potential for functional impairment (eg, periorbital IHs), ulceration (that may cause pain or scarring), and associated underlying abnormalities (eg, intracranial and aortic arch vascular abnormalities accompanying a large facial IH). This clinical practice guideline for the management of IHs emphasizes several key concepts. It defines those IHs that are potentially higher risk and should prompt concern, and emphasizes increased vigilance, consideration of active treatment and, when appropriate, specialty consultation. It discusses the specific growth characteristics of IHs, that is, that the most rapid and significant growth occurs between 1 and 3 months of age and that growth is completed by 5 months of age in most cases. Because many IHs leave behind permanent skin changes, there is a window of opportunity to treat higher-risk IHs and optimize outcomes. Early intervention and/or referral (ideally by 1 month of age) is recommended for infants who have potentially problematic IHs. When systemic treatment is indicated, propranolol is the drug of choice at a dose of 2 to 3 mg/kg per day. Treatment typically is continued for at least 6 months and often is maintained until 12 months of age (occasionally longer). Topical timolol may be used to treat select small, thin, superficial IHs. Surgery and/or laser treatment are most useful for the treatment of residual skin changes after involution and, less commonly, may be considered earlier to treat some IHs.

Primordial germ cells (PGCs) were isolated from blood samples of chicken embryos. We established four PGC lines: two males (FS-ZZ-101, GFP-ZZ-4ZP) and two females (FS-ZW-111, GFP-ZW-5ZP). We could not detect a significant difference in the marker expression profile, but there was a remarkable difference between the proliferation rates of these PGC lines. We monitored the number of PGCs throughout a three-day period using a high-content screening cell imaging and analysing system (HCS). We compared three different initial cell concentrations in the wells: ~1000 cells (1×, ~4000 (4× and ~8000 (8×. For the GFPZW- 5ZP, FS-ZZ-101 and FS-ZW-111 PGC lines the lowest doubling time was observed at 4× concentration, while for GFP-ZZ-4ZP we found the lowest doubling time at 1× concentration. At 8× initial concentration, the growth rate was high during the first two days for all cell lines, but this was followed by the appearance of cell aggregates decreasing the cell growth rate. We could conclude that the difference in proliferation rate could mainly be attributed to genotypic variation in the established PGC lines, but external factors such as cell concentration and quality of the culture medium also affect the growth rate of PGCs.

Published: December 2018

The Lusitano horse is an autochthonous Portuguese breed with a growing worldwide expansion. Our objective was to establish reference intervals for haematological parameters using the haematological cell counter LaserCyte (IDEXX). For this purpose, blood samples from 100 healthy adult horses (13 females and 87 males, ranging from 3 to 25 years of age) were analysed. The reference intervals were estimated following the ASVCP guidelines with the Reference Value Advisor software. The obtained reference intervals were 6.4–10.1 × 1012/L for red blood cells, 30.6–45.1% for haematocrit, 11.6–17.1 g/dL for haemoglobin, 42.8–53.2 fL for mean corpuscular volume (MCV), 15.5–20.8 pg for mean corpuscular haemoglobin (MCH), 33.7–39.4 g/dL for mean corpuscular haemoglobin concentration, 17.8–20.3% for red cell distribution width (RDW), 4.5–10.1 × 109/L for white blood cells, 2.2–6.0 × 109/L for neutrophils, 0.9–4.9 × 109/L for lymphocytes, 0.2–0.5 × 109/L for monocytes, 0.1–0.6 × 109/L for eosinophils, 0.0–0.1 × 109/L for basophils, 78.5–172.2 K/mL for platelets, 4.3–9.4 fL for mean platelet volume, 18.8–24.2% for platelet distribution width, and 0.06–0.12% for plateletcrit. LaserCyte equine reference intervals are transferable to the Lusitano horse for 18 of the 22 analytes studied. Regarding age, significant statistical differences were observed for MCV, RDW, neutrophils and lymphocytes between the mean values of young (3–6 years old), middle-aged (7–14 years old) and old (< 15 years old) age groups. MCH means were statistically significantly different between the three age groups. The haematological reference intervals established in this study might represent a valuable and applicable tool for haematological assessment of adult Lusitano horses, providing useful information that helps clinicians to interpret clinical data.

Published: December 2018

The authors studied the present status of Hungarian indigenous sheep breeds based on the genetic background of scrapie resistance. The aim of this investigation was to estimate the relative frequency of prion haplotypes, genotypes and risk categories, as well as to reveal the efficiency of the scrapie eradication programme achieved over the last decade. A novel approach in the characterisation of prion by using its genic variation was also implemented. The authors established that the proportion of deleterious sites (%) can be a useful indicator of the eradication programme. Based on a large sample size, it was confirmed that the scrapie resistance of the Cikta breed is low, and the classification of this breed according to risk category has not improved. However, the frequent genotype ARQ and risk category 3 can also be considered characteristic of the breed. The careful use of these genotypes is permitted and will contribute to the maintenance of breed diversity. The response of prion genic variation to selection for scrapie resistance in the other breeds (Tsigai, Milking Tsigai, White Racka, Black Racka and Gyimes Racka) was definitely successful.
Young people’s recall and perceptions of gambling advertising and intentions to gamble on sport
Authors: Nyemcsok Christian , Thomas Samantha L. , Bestman Amy , Pitt Hannah , Daube Mike , Cassidy Rebecca
Published: December 2018

Background

There has been an increased international policy focus on the factors that may contribute to, and prevent, the normalization of gambling for young people. However, there is still limited research, which investigates the role of advertising in shaping young people’s gambling attitudes and consumption intentions.

Methods

Mixed methods study of 111 young people aged 11–16 years recruited from community basketball stadiums in Victoria, Australia, between May and July 2018. Interviewer-assisted surveys investigated recall and awareness of sports betting brands, perceptions of promotional strategies, intention to gamble, and reasons for betting on particular sports. Quantitative data were analyzed using descriptive statistics and χ2tests. Thematic analyses were used to interpret qualitative responses.

Results

Young people had high recall and awareness of advertising, with most able to name at least one betting brand (n = 90, 81.1%), and many demonstrating a high awareness of the distinct characteristics (such as colors and appeal strategies) of different brands. A fifth of young people (n = 25, 22.5%) expressed intentions to gamble at 18 years, with boys significantly more likely than girls to state they would gamble (χ2 = 10.90,p = .001). Young people perceived that advertising strategies associated with inducement promotions would be the most influential in encouraging individuals to gamble. While many young people took promotions at face value, there was evidence that some were able to critically engage with and challenge the messages within marketing.

Discussion and conclusions

Current regulatory structures appear to be ineffective in limiting young people’s recall and awareness of gambling advertising. Lessons from tobacco control support the application of precautionary approaches as a more effective way to limit young people’s development of positive gambling attitudes and behaviors.
Suicidal ideation and history of suicide attempts in treatment-seeking patients with gambling disorder: The role of emotion dysregulation and high trait impulsivity

Published: December 2018

Background and aims

Gambling disorder (GD) presents high rates of suicidality. The combined influences of emotion dysregulation and trait impulsivity are crucially important (albeit understudied) for developing strategies to treat GD and prevent suicide attempts. The aim of this study is to investigate the association between trait impulsivity, emotion dysregulation, and the dispositional use of emotion regulation (ER) strategies with suicidal ideation and psychopathological symptom severity in GD.

Methods

The sample composed of 249 patients with GD (166 with suicidal ideation) who underwent face-to-face clinical interviews and completed questionnaires to assess psychopathological symptoms, impulsive traits, and ER.

Results

Patients with GD who presented suicidal ideation were older and had a later age of GD onset and higher GD severity. Analyses of variance showed higher comorbid symptoms, emotion dysregulation, and trait impulsivity in patients with suicidal ideation. Still, no significant differences were found in the use of ER strategies. SEM analysis revealed that a worse psychopathological state directly predicted suicidal ideation and that both emotion dysregulation and GD severity indirectly increased the risk of suicidal ideation through this state. High trait impulsivity predicted GD severity. Finally, a history of suicide attempts was directly predicted by suicidal ideation.

Conclusions

Patients with GD are at risk of presenting suicidal behaviors. The results of this study revealed the importance of comorbid psychopathology in the occurrence of suicidal ideation and the indirect effect of trait impulsivity and emotion dysregulation on suicidality. Thus, suicidal rates in GD could possibly be reduced by specifically targeting these domains during treatment.
Allantoin improves histopathological evaluations in a rat model of gastritis
Authors: Eslami-farsani M , Moslehi A , Hatami-shahmir A
Published: December 2018

Purpose

Gastritis is found to be one of the most common gastrointestinal diseases worldwide. However, current therapeutic agents cause side effects, interaction, and recurrence. Allantoin has anti-inflammatory and wound healing properties. In this study, the therapeutic effect of allantoin has been assessed on the histopathological indices and gastric mucosal barrier of male rats.

Methods

Male rats were equally divided into control, ethanol-induced gastritis, and allantoin groups. The therapeutic groups consisted of gastritis plus 12.5 mg/kg allantoin, gastritis plus 25 mg/kg allantoin, and gastritis plus 50 mg/kg allantoin groups. After 5 days of allantoin administration, the rats were sacrificed and a part of their gastric tissue was maintained at −70 °C for prostaglandin E2 (PGE2) and non-protein sulfhydryl (NP-SH) measurements. Another part was stained with hematoxylin and eosin and Masson’s trichrome.

Results

We found that Allantoin increased parietal and mucosal cell counts and mucosal thickness after gastritis induction. In addition, the number of leukocytes and vessels decreased in both of the mucosal and the submucosal layers. Allatoin improved gastric ulcer in all treatment groups. Gastric levels of PGE2 and NP-SH increased after allantoin treatment.

Conclusion

This study indicated that allantoin had a considerable effect on gastritis treatment, which seems to result from the reinforcement of gastric mucosal barrier.

Abstract:

Introduction: Endonasal dacryocystorhinostomy (EDCR) has good results. Aim: To perform a prospective histological investigation of the removed lacrimal sacs’ walls. Method: Between 2016 and 2017, we carried out 21 operations in two groups: inflammatory (11 patients) and non-inflammatory (10 patients) lacrimation groups. The mean age was 60.5 years. Histological samples were investigated after staining them with hematoxylin-eosin. Results: In the non-inflammatory group, histology revealed the incipient metaplasia of the ciliated goblet cells. In the lacrimal sac’s wall, there is a chronic inflammation with mucinous metaplasia of the serous glands. In the inflammatory group, the metaplasia of the ciliated goblet cells is more pronounced. Chronic fibrotic inflammation destroys the lacrimal sac’s wall, which is dilated, ruptured. The mucinous metaplasia of the serous glands is pronounced. Conclusions: The results of histological investigations of the lacrimal sacs removed in the course of EDCR are much alike in the inflammatory and non- inflammatory groups.

Published: December 2018

Abstract:

Gastrointestinal tract duplications (GSD) are rare congenital abnormalities. Eighty percent of GSDs are diagnosed before the age of two. These lesions can be seen anywhere from the oral cavity to the anus, but ileum is the most commonly affected site. Their clinical presentation is widely variable and unspecific, making the differential diagnosis really hard. Thus despite performing a long line of radiological scans, the diagnosis can be made during a surgery and by the pathologist. A 23-year-old female patient presented at the emergency room (ER) with abdominal cramps. Examinations revealed an unidentified intraabdominal mass. This could not been identified through the next years despite having tons of examinations: intravaginal and abdominal ultrasonographies, CT and MRI scans, colonoscopies, laparoscopies, surgical, gynecological and gastroenterological visits. Amongst the diagnoses were: ovarian cyst, bowel enlargement, Crohn’s disease. Due to the latter, she received therapy which temporarily eased her symptoms. But after these, because of abdominal pain, fever and an ultrasonography that showed an intramural abscess in her abdomen, she went through a surgery having an ileocecal resection. Pathological examination showed a duplication of the ileum that might have caused her symptoms all through the years. Despite facing this rare abnormality, it is important to keep this in mind in differentiating abdominal symptoms. It is true that in no case there could be a diagnosis made without surgery, it raises attention to the importance of precise medical history taking and also cooperation between specialties.

Megújulás az alsó végtagi varicositas műtéti kezelésében
Authors: Bihari Imre
Published: December 2018

Abstract:

During the 20th century, continuous development of classic varicose vein surgery was carried out. From the beginning of the 21st century, however, new endovascular interventions were introduced. Compared to classic surgery, their main benefit is that no incision and dissection is necessary. Only catheters are used to scar the saphenous stems, which are introduced via punctures. Before and during the intervention, ultrasound is used. Laser surgery is the most popular option, and its outcomes have improved a lot with the introduction of laser crossectomy. Radiofrequency surgery is another intervention which is widely performed. A further heat ablation method is the steam operation. One newer technique is the cyanoacrylate tissue adhesive operation. The well-known practice of sclerotherapy has developed by turning the liquid sclerosant into foam, and by causing mechanical damage to the intimal layer of the vein. The new methods have fewer complications because these avoid incisions and dissections during the interventions. Orv Hetil. 2018; 159(52): 2195–2201.

Published: December 2018

У статті розглядаються основні теоретико-методичні аспекти оцінки рівня ризикованості діяль-ності підприємств. Кількісна оцінка ризиків в цілому передбачає розв’язання двох завдань: вибір мето-ду оцінки ризиків та визначення міри та ступеня ризику у вигляді показника, або групи показників. Ве-лика кількість показників, яка використовується в практиці управління ризиками, вимагає їх системати-зації, що і було проведено автором.Вибір кількісних показників, які доцільно застосовувати в кожній конкретній ситуації, залежитьвід певних чинників, серед яких ключовими є наявність інформації щодо кількісних характеристик ри-зику, виду ризику, обмеження ресурсів, в тому числі часу, вимог щодо повноти вихідної інформації дляприйняття управлінських рішень.

Published: December 2018

В статті розкрито сутність глобальної та географічної моделі соціальної відповідальності. Від-мічено, що глобальна модель соціальної відповідальності базується на етичній поведінці бізнесу, гео-графічна модель представлена трьома теоріями: корпоративного егоїзму, корпоративного альтруїзмута розумного егоїзму. До основних національних моделей соціальної відповідальності віднесено аме-риканську, європейську, японську. Доведено, що американська модель суспільної відповідальностібазується на потужних активностях бізнесу при слабкому впливу центральних органів держави тагромадських організацій. В європейській моделі бізнес при вирішенні соціальних проблем активно вза-ємодіє з державою, некомерційними організаціями та іншими громадськими інститутами. В японськіймоделі підприємство асоціюється з «виробничою сім’єю», де працівник несе відповідальність і корис-тується правами, виходячи далеко за рамки трудових обов’язків. Дано авторське визначення термінудля українських реалій полягає в доповненні і набуває наступного значення «соціальна відповідаль-ність» – це спроба вирішити соціальні проблеми, які повністю або частково спричинені діяльністю під-приємств та непрофесійними і безвіподальними діями владних структур держави.

Introduction. Sleep problems are frequent in patients with attention deficit hyperactivity disorder (ADHD), but often underestimated in clinical settings. Objective. To describe the main characteristics of sleep habits in an ADHD outpatient population using the Children Sleep Habits Questionnaire-Abbreviated (CSHQ-A) to compare ADHD groups according to the presence of comorbidity and the presence of current treatment, and to determine sleep profiles by using latent class analysis (LCA). Method. A sample of 228 ADHD patients (Mage = 11.5 years old, (IR = 9 - 15) were enrolled. ADHD comorbidities and treatments were registered. Parents/caregivers filled out the questionnaire. Participants groups were compared, and LCA was used to classify profiles of similar sleep patterns. Results. The ADHD group with treatment had a higher score in the CSHQ-A than the group without treatment. Four classes emerge: Class 1 only children, males, half with comorbid ADHD, many with treatment, and with many sleep problems (CSHQ-A mean: 25.98). Class 2: mostly adolescents, female, with comorbid anxiety disorder, and who did not show sleep problems (CSHQ-A mean: 12.78). Class 3: only adolescents, males, comorbid with major depressive disorder and CSHQ-A who showed many sleep problems. Class 4: only children, males, the majority with treatment, with some sleep problems. Discussion and conclusion. In this ADHD sample, patients with psychopharmacological treatment have a greater report of sleep problems by the CSHQ-A compared to those who do not receive treatment.
