Disseminated genital herpes and mode of delivery
Authors: Odak Zdravko , Roje Damir , Vulić Marko 
Published: August 2017

Abstract
Genital herpes in pregnancy is associated with increased perinatal morbidity and mortality. Maternal primary infection with herpes simplex virus (HSV) prior to labor usually does not affect the fetus (1/200,000 deliveries) The greatest risk associated with intrapartum HSV exposure is neonatal herpes infection. Neonatal risk occurs in the case of a primary or reccurent HSV infection. The risk of neonatal HSV infection in case of non-genital herpes is low. The American Congress of Obstetricians and Gynecologists (ACOG) recommends elective cesarean delivery for women with demonstrable genital herpes or prodromal symptoms in labor.
Genetic survey of alveolar and cystic echinococcoses in Romania: first molecular evidence of Echinococcus multilocularis in humans in the country

Published: August 2017

Summary
Cystic echinococcosis (CE) and alveolar echinococcosis (AE) are considered as one of the most important zoonotic diseases in Romania, where they are subject to mandatory reporting. To obtain more knowledge about the genetic diversity of Echinococcus causative agents of these diseases, 11 isolates from humans and ungulate intermediate hosts from the two regions of Romania were genotyped using mitochondrial markers. In clinical samples of five patients from north-eastern Romania (Iasi, Botosani, Vaslui counties), Echinococcus multilocularis was identified as causal agent by cox1 sequence analysis. To the best of our knowledge this finding presents the first molecular evidence of E. multilocularis in humans from Romania. Only two cases of AE in patients were previously documented in the country by serological methods. In our four patients the most widespread European variant E5 of E. multilocularis was recorded, whereas in isolate from Vaslui county three nucleotide substitutions were detected as compared to the most related E5 haplotype. One of these mutations (411T/G) matched N1 and N2 haplotypes described previously from North America. In six CE samples retrieved from western Romania (Caras-Severin and Timis counties), two human isolates were diagnosed as Echinococcus canadensis G7, one as E. granulosus s.s. G1 and one as E. granulosus s.s. G3 using atp6 and rrnS sequencing. In ungulates, the cattle isolate was allocated to E. granulosus s.s. G1 and pig isolate to E. canadensis G7. The two G7 findings in humans reinforced the recent view that G7 was underestimated as compared to the E. granulosus s.s. regarding human CE threat that can be further employed for identifying sources of infections and establishing suitable preventive measures.

Summary
The occurrence of parasitic infections among the children, dogs and its association with soil contamination in two villages with different hygiene level standards were analysed. Infections were present in both examined localities, but in the village with higher living standard, a better personal and communal hygiene level and better dogs care a lower occurrence of parasitic germs in soil was detected. High prevalence of protozoa and helminths was observed not only within canine population but also in children throughout the year in the village with lower hygiene and socio-economic standard. We have identified up to 12 taxa of parasites in 127 collected dogs’ excrements and mean prevalence was 71.65 %. The most frequent were eggs of family Ancylostomatidae and Ascaris spp., followed by Toxocara canis, Toxascaris leonina, Giardia duodenalis cysts, Isospora spp. oocysts, eggs of Capillaria aerophila, Trichuris vulpis, Taenia type eggs, Dipylidium caninum, oocysts of Sarcocystis spp. and larvae of Angiostrongylus vasorum. The soil samples collected near dwellings were highly contaminated. Two thirds of samples contained eggs for the most part of family Ancylostomatidae as well as genera Ascaris and Toxocara. Among the kids population helminth ova were present in 53.17 % of stool samples, where the eggs of Ascaris lumbricoides, Trichuris trichiura, Enterobius vermicularis, Hymenolepis diminuta and cysts of G. duodenalis were the most frequent. In contrast, parasitic diseases were not seen in children population living in the locality with common hygiene standard.

Authors: Babják M. , Königová A. , Urda-Dolinská M. , Várady M. 
Published: August 2017

Summary
The aim of this study was to identify the most common gastrointestinal (GI) parasites in flocks of dairy goats on 30 farms in Slovakia. A total of 944 adult goats were examined during the pasturing seasons for 2014 – 2016. Eggs from one or more species of gastrointestinal parasites were identified in 906 of the samples (95.90 %). Strongyle eggs were present in most of the samples (92.00 %), followed by Strongyloides papillosus (14.05 %), Trichuris spp. (7.84 %), Nematodirus spp. (3.98 %), and Moniezia spp. (2.65 %). The counts of strongyle eggs per gram of faeces ranged from 0 to 11 000. Subsamples from each farm were used to prepare faecal coprocultures to identify the genera of the nematodes. Third-stage larvae of Trichostrongylus spp. (100 %) and Teladorsagia/Ostertagia spp. (96.60 %) were present on most of the farms, followed by Oesophagostomum spp./Chabertia ovina (86.60 %) and Haemonchus contortus (76.60 %). Teladorsagia/Ostertagia spp. were the dominant genera on 60 % of the farms.
Helminth parasite communities of spotted rose snapper Lutjanus guttatus from the Mexican Pacific
Authors: Morales-Serna F. N. , García-Vargas F. , Medina-Guerrero R. M. , Fajer-Ávila E. J. 
Published: August 2017

Summary
The helminth communities of L. guttatus from Mazatlan Bay (MB) and Banderas Bay (BB), on the Pacific coast of Mexico, were studied during two consecutive years. A total of 536 fish were collected and 19 parasite taxa registered (six digeneans, two cestodes, nine nematodes, and two monogeneans). Infection levels of common helminth species (Helicometrina nimia, Siphodera vinaledwardsii, Tetraphyllidea gen. sp., Pseudoterranova sp., Ancyrocephalidae gen. sp. and Microcotyloides incisa) as well as the infracommunity indices varied significantly between MB and BB, and among dry and rainy seasons; however, no clear seasonal patterns were observed. Pseudoterranova larvae appeared frequently in MB, possibly because of the presence of the California sea lion in this locality. Similarity analysis did not show a clear separation of parasite species composition between both localities, which suggest that fish samples came from a single population of L. guttatus.
Morphological and molecular characteristics of foliar nematode attacking silver birch (Betula pendula Roth) in Poland

Published: August 2017

Summary

Aphelenchoides fragariae (Ritzema Bos, 1890) Christie, 1932 was isolated from leaves of silver birch (Betula pendula Roth) seedlings proving that the source of infection was anemones plants. This is the first report to our best knowledge showing that the source of nematode infection of a woody plant could be a perennial plant. A. fragariae was identified by morphometric and molecular analyses. Morphological diagnosis based on the bending shape of the tail of males and pronounced apex and rostrum proved to be the most accurate reliable characteristic. On the opposite, the high variability of the mucron shape in female tails made the identification by microscopic analyses difficult. Identification of the species was confirmed by analysis of 28S rDNA sequences. The morphometric data of adults extracted from silver birch was compared with that of nematodes isolated from Anemone hupehensis (Lemoine) Lemoine. Males body length varied highly in samples collected from both host plant species.
The functional significance of 14-3-3 proteins in cancer: focus on lung cancer
Authors: Khorrami Afshin , Sharif Bagheri Mahyar , Tavallaei Mahmood , Gharechahi Javad 
Published: August 2017

Abstract
The 14-3-3 family proteins are phosphoserine/phosphothreonine binding proteins constituting a conserved class of proteins which are detected in all eukaryotic cells. In mammalians, 14-3-3 proteins have seven distinct isoforms (β, γ, ε, η, ζ, σ and τ/θ) which are involved in various cellular processes including signal transduction, cell cycle, cell proliferation, apoptosis, differentiation and survival. 14-3-3 proteins do not have a distinct catalytic activity and often regulate the activity, stability, subcellular localization and interactions of other proteins. The 14-3-3 family proteins function through interacting with their client proteins or facilitating the interaction of other proteins likely as adaptor proteins. The versatile functions of these proteins in the regulation of cell growth, cell division, cell death and cell migration make them candidate proteins for which an important role in cancer development could be envisioned. Indeed, analysis of cancer cell lines and tumor-derived tissues have indicated the differential abundance or post-translational modification of some 14-3-3 isoforms. In this review, we aimed to show how deregulation of 14-3-3 proteins contributes to initiation, establishment and progression of cancers with a particular emphasis on lung cancer. The role of these proteins in cancer-relevant processes including cell cycle, cell migration, cell-cell communication and programmed cell death will be discussed in detail.

Published: August 2017

AbstractCytochromes P450 (CYPs) are important for bone homeostasis, but only limited information is available on their expression in human bone cells. We analyzed the expression levels of eight CYPs in osteoblasts cultured in human bone pieces, in osteoblasts differentiated from human periosteum mesenchymal stem cells, in primary human osteoblasts and in the human osteoblast cell line MG63, respectively. Our results confirm previous reports about the presence of CYP11A1, CYP17A1, CYP24A1 and CYP27B1, while demonstrating expression of CYP2E1, CYP26A1, CYP39A1 and CYP51A1 for the first time. However, expression patterns in the four models were remarkably different from each other.
Determination of Listeria monocytogenes numbers at less than 10 cfu/g
Authors: Hunt K. , Vacelet M. , Jordan K. 
Published: August 2017

AbstractListeria monocytogenes is a foodborne pathogen that causes a relatively rare foodborne disease called listeriosis, with a high mortality rate of 20%-30% and an undefined dose response. Current European Union regulations permit up to 100 colony-forming units (cfu)/g in food at the end of its shelf life, where the food has been shown not to support the growth of this pathogenic bacterium. Therefore, enumeration of L. monocytogenes at low numbers in food is important. The objective of this study was to reduce the detection limit of L. monocytogenes in food by a factor of 10. The International Organisation for Standardisation (ISO) 11290-2 method for enumeration of L. monocytogenes in food recommends spreading 0.1 mL of a 1:10 dilution of the food on the surface of an agar plate (detection limit 100 cfu/g), or 1.0 mL spread in equal parts on the surface of three agar plates (detection limit: 10 cfu/g). The pour-plate method (using 1 or 10 mL of an appropriate dilution) was compared to the spread-plate method using the ISO-approved chromogenic medium Agar Listeria according to Ottaviani and Agosti (ALOA). Using the pour-plate method, the colony morphology and halo formation were similar to the spread-plate method from pure cultures and inoculated foods. Using the pour-plate method in a 140 mm Petri dish, 10 mL of a 1:10 dilution of food allowed determination of numbers as low as 1 cfu/g. Applying this method, L. monocytogenes in naturally contaminated food samples were enumerated at numbers as low as 1-9 cfu/g.
Trichotillomania in celiac disease patient refractory to iron replacement
Authors: Kalyoncu Tuğba , Çıldır Deniz Argüz , Özbaran Burcu 
Published: August 2017

Abstract
Trichotillomania is characterized by recurring hair pulling behavior and repeated attempts to decrease or stop the behavior. This behavior can cause a trichobezoar, which is a mass of hair found in the stomach. Patients with diagnosed celiac disease may have an urge to swallow their hair due to iron or folat deficiency, which is called pica. We report a case of an 11-year old girl with celiac disease who has had trichotillomania for a duration of 2 years, and required an operation due to residual gastric hair mass. In this case trichotillomania was more likely caused by behavioral disorders secondary to celiac disease, rather than the iron deficiency due to malabsorption.
From child to grown up in a medical world: developing an adolescent transition programme at a Norwegian University hospital
Authors: Sirevåg Kjersti , Fløtten Kjersti J.Ø. , Nakstad Britt , Hvideberg Aud Inger , Odden Jan Petter , Roy Betty Van 
Published: August 2017

Abstract

Background
Akershus University Hospital has since 2012 worked systematically towards improving the process of transfer for adolescents from the Department for Paediatric and Adolescent Medicine (DPAM) to adult services in our hospital.

Objective
To improve the transfer process of adolescents we aimed at moving from a more administrative focus on transfers to a transition programme. The aim was both short-term and long-term gains, namely quality improvement of the healthcare we are providing and valued health promotion outcomes.

Methods
A guided transition programme for adolescents was developed, piloted and introduced. It was developed in close collaboration with our youth council. An e-learning programme and a handbook for health care professionals were developed for implementation.

Results
Data from the pilot testing the transition programme show that the adolescent participants found the information material to be relevant. They reported that it was used actively by the health professionals in their consultations and that they found this to be helpful. It was crucial that the management acknowledged and took responsibility for the programme. We experienced that a shared understanding of the adolescent patient in both sending and receiving departments was crucial.

Conclusion
Adolescent medicine should include competence and professionalism. Health care personnel must possess knowledge, skills and attitude that enable good, health promoting encounters. Further evaluation of pre- and post-implementation clinical outcomes, of patient empowerment and of satisfaction among employees will need to follow for evaluation of the effectiveness of this transition programme.
Attitudes and behaviors related to distracted driving in college students: a need for interventions in adolescence
Authors: Basch Corey H. , MacLean Sarah A. , Garcia Philip 
Published: August 2017

Abstract

Objective
One of the biggest contributors to distracted driving among young people in the United States is technology. The objective of this study was to describe distracted driving behaviors among college students, with a specific focus on attitudes towards and use of social media.

Methods
With written permission, a survey was adapted from the Distracted Driving Public Opinion Poll distributed by the National Safety Council. The survey comprised 43 questions assessing attitudes and behaviors. A total of 411 students enrolled in a personal health course were invited to complete the survey. In total 324 surveys were completed, resulting in a response rate of 79%.

Results
Among students with a driver’s license, 95.2% reported engaging in distracted driving behaviors. The use of social media while driving was common, with 30.7% reporting that they glance at, read, or post to social media while driving, most commonly on Snapchat or Instagram. It was common for students to make or answer phone calls (72.0%), review or send text messages (54.6%), or glance at or read automatic notifications (43.3%). Almost all students (91.5%) reported that they believed a hands-free solution is safer than holding the phone while driving, but only 67.9% reported that they usually used a hands-free device. Students in a health major and students who drive in urban areas were more likely to engage in distracted driving behaviors.

Conclusions
These findings suggest a need for interventions, particularly those which target adolescents in an attempt to deter these behaviors as they transition into adulthood.
Gastric cancer in a teenager: a case report
Authors: Ghersin Itai , Katz Lior H. 
Published: August 2017

Abstract

Background
Gastric cancer occurs mainly in older patients, with a peak incidence over 60 years of age. It is relatively rare among younger individuals. However, the frequency of gastric cancer in young patients appears to be on the rise worldwide.

Case presentation
We report the case of a 19-year-old female soldier who, after a considerable diagnostic delay, was diagnosed with gastric adenocarcinoma. She is one of the youngest gastric adenocarcinoma patients ever reported in Israel.

Conclusion
This case should serve as a reminder that gastric carcinoma is a possible diagnosis even in young patients. It also highlights the critical importance of obtaining a thorough medical history in the process of clinical decision making.
Spatiotemporal Assessment of Vegetation Indices and Land Cover for Erbil City and Its Surrounding Using Modis Imageries
Authors: Hussein Shwan O. , Kovács Ferenc , Tobak Zalán 
Published: August 2017

AbstractThe rate of global urbanization is exponentially increasing and reducing areas of natural vegetation. Remote sensing can determine spatiotemporal changes in vegetation and urban land cover. The aim of this work is to assess spatiotemporal variations of two vegetation indices (VI), the Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI), in addition land cover in and around Erbil city area between the years 2000 and 2015. MODIS satellite imagery and GIS techniques were used to determine the impact of urbanization on the surrounding quasi-natural vegetation cover. Annual mean vegetation indices were used to determine the presence of a spatiotemporal trend, including a visual interpretation of time-series MODIS VI imagery. Dynamics of vegetation gain or loss were also evaluated through the study of land cover type changes, to determine the impact of increasing urbanization on the surrounding areas of the city. Monthly rainfall, humidity and temperature changes over the 15-year-period were also considered to enhance the understanding of vegetation change dynamics. There was no evidence of correlation between any climate variable compared to the vegetation indices. Based on NDVI and EVI MODIS imagery the spatial distribution of urban areas in Erbil and the bare around it has expanded. Consequently, the vegetation area has been cleared and replaced over the past 15 years by urban growth.
Convexification of restricted Dirichlet-to-Neumann map
Authors: Klibanov Michael V. 
Published: August 2017

Abstract
By our definition, “restricted Dirichlet-to-Neumann (DN) map” means that the Dirichlet and Neumann boundary data for a coefficient inverse problem (CIP) are generated by a point source running along an interval of a straight line.
On the other hand, the conventional DN data can be generated, at least sometimes, by a point source running along a hypersurface.
CIPs with restricted DN data are non-overdetermined in the n-dimensional case, with

n
≥
2

{n\geq 2}

.
We develop, in a unified way, a general and radically new numerical concept for CIPs with restricted DN data for a broad class of PDEs of second order, such as, e.g., elliptic, parabolic and hyperbolic ones.
Namely, using Carleman weight functions, we construct globally convergent numerical methods.
Hölder stability and uniqueness are also proved.
The price we pay for these features is a well-acceptable one in the numerical analysis, that is, we truncate a certain Fourier-like series with respect to some functions depending only on the position of the point source.
At least three applications are imaging of land mines, crosswell imaging and electrical impedance tomography.
Coda: Ten Questions for a Diplomat
Authors: Weisbrode Kenneth 
Published: August 2017

AbstractThomas Niles served as a United States foreign service officer from 1962 to 1998. His service included three terms as ambassador: to Canada, the European Community, and Greece. He reflects here on the continuities in the diplomatic profession, and, in particular, on embassies, during a period of notable historic change. While many of the protocols and responsibilities of embassies remained more or less the same as they had been for over a century, there were hints that those, too, were about to change in unforeseen ways, even calling into question the central role of embassies as representing and serving the nation-state, as the other articles in this issue discuss. Nevertheless, to this ambassador, at least, even dramatic changes in technology, politics, and culture rarely happen all at once; and the institutions and the people adapting to them may be more cautious or durable than they sometimes appear in retrospect.
