TEO: Minimálisan invazív rectumsebészet. Rövid áttekintés
Authors: Zaránd Attila 
Published: February 2014

Absztrakt
Buess az 1980-as évek elején dolgozta ki a transanalis endoscopos mikrosebészeti technikát, és kifejlesztette a műtéthez használt speciális eszközparkot is. A technika azóta finomodott, sőt a javallati indikációs kör is bővült. Megfelelően kiválasztott betegeknél kitűnő onkológiai eredmények érhetők el, a műtéti terhelés kisebb, a szövődmények előfordulása pedig a hagyományos technikákhoz képest igen alacsony. Napjainkban a jóindulatú, illetve az alacsony malignitású T1-es daganatok kezelésében „gold standard” a transanalis endoscopos mikrosebészeti technika.

Absztrakt
Az autoimmun pancreatitis (AIP) egy ritka és pathomechanismusát tekintve ismeretlen betegség, amely az IgG4-asszociált betegségek családjába tartozik. Jól kezelhető steroiddal, bár a relapsus aránya a 20–30%-ot is elérheti. Komoly differenciáldiagnosztikai problémát jelenthet azonban az elkülönítése a jóval gyakoribb pancreasdaganattól. Az esetek mintegy 20%-ában csak a műtét utáni szövettani vizsgálat során derül ki az AIP. A számtalan vizsgálóeljárás mindegyike hozzátesz valamit a definitív diagnózishoz, kérdés, hogy elkerülhetőek-e a felesleges resectiók. Eset­ismertetésünk segítségével kívánjuk bemutatni az AIP és a pancreasdaganat differenciáldiagnosztikai lehetőségeit, illetve a kérdés irodalmi hátterét. Konklúzióként megfogalmazhatjuk, hogy focalis pancreaselváltozás esetén gondolnunk kell az AIP lehetőségére is.
STRESS-MODULATED DRIVING FORCE FOR LITHIATION REACTION IN HOLLOW NANO-SPHERICAL ANODES
Authors: Jia Zheng , Li Teng 
Published: February 2014

ABSTRACTRecent experimental evidence on nano-particle and nano-wire silicon anodes showed an initial rapid velocity of reaction front at the initial stage of lithiation, followed by an apparent slowing or even halting of the reaction front propagation. This intriguing phenomenon is attributed to the lithiation-induced mechanical stresses across the reaction front which is believed to play an important role in the kinetics of reaction at the front. Here, through theoretical formulation, we presented a comprehensive study on lithiation-induced stress field and its contribution to the driving force of lithiation in hollow spherical anodes with different boundary conditions at the inner surface of the particle. Our results reveal that hollow spherical silicon anodes can be lithiated more easily than solid spherical silicon particles and thus may serve as an optimal design of high performance anodes of lithium-ion battery.

Published: February 2014

Objective This study explored posterior nasopharyngeal augmentation with an acellular dermal matrix sheeting. Design Evaluation of the persistence and safety of a submucosal implant of rolled acellular dermis over a 3-month period in a piglet model. Setting Institute Hills Facility, part of the Mayo Clinic Rochester health care facility. Participants Fifteen 5-week-old domestic piglets of unspecified gender. Interventions Twelve piglets were implanted at age 5 weeks with a rolled sheet of acellular dermal matrix (Strattice). Implants were inserted in a submucosal pocket in the soft palate. Three piglets underwent sham operations, with creation of submucosal pockets without implantation. After a 3-month observation period, the palates were harvested for evaluation. Results Grossly, persistence of bulk at the surgical site in 5 of the 12 implanted piglets was noted at 3 months. Histologically, no persistence of the dermal matrix could be observed. Incorporation and/or resorption of the dermal matrix occurred with minimal to no host inflammatory response. Conclusion This experiment demonstrated the safety of a rolled acellular dermal implant in a submucosal location in a pig model, without surgical complication, host inflammatory reaction, or rejection. Minimal, if any, bulk of the implant persisted in the implanted location after 3 months. Although acellular dermal matrix sheeting appears to be safe and well-tolerated, it does not offer a long-term treatment option for posterior pharyngeal augmentation.

Abstract

Learning Objectives
Describe the quality of life changes that can occur during neoadjuvant therapy for esophageal cancer. Explain the use of esophageal stenting during neoadjuvant therapy for esophageal cancer.

Purpose.
To determine whether self-expanding plastic stent (SEPS) placement significantly improves quality of life and maintains optimal nutrition while allowing full-dose neoadjuvant therapy (NAT) in patients with esophageal cancer.

Patients and Methods.
A prospective, dual-institution, single-arm, phase II (http://ClinicalTrials.gov: 00727376) evaluation of esophageal cancer patients undergoing NAT prior to resection. All patients had a self-expanding polymer stent placed prior to NAT. The European Organisation for Research and Treatment of Cancer QLQ-C30 and QLQ-OG25, Functional Assessment of Cancer Therapy–Anorexia, and Functional Assessment of Cancer Therapy–General surveys were administered prior to stenting, within 1 week post-stent placement, and at the completion of neoadjuvant therapy.

Results.
Fifty-two patients were enrolled; 3 (5.8%) had stent migrations requiring replacement. There were no instances of esophageal erosion or perforation. All patients received some form of neoadjuvant therapy. Thirty-six (69%) received chemoradiation; 34 (93%) of these patients received the planned dose of chemotherapy, and 27 (75%) received the full planned dose of radiotherapy. There were 16 (31%) patients receiving chemotherapy alone; 12 (74%) of patients in the chemotherapy-alone group completed the planned dose of therapy.

Conclusion.
Placement of SEPS appears to provide significant improvement in quality of life related to dysphagia and eating restriction in patients with esophageal cancer undergoing neoadjuvant therapy. Consideration of SEPS instead of percutaneous feeding tube should be initiated as a first line in dysphagia palliation and NAT nutritional support.
Codification of the Economic Substance Doctrine and the Gregory Case
Authors: Flesher Tonya K. , Quinn Tina Steward 
Published: February 2014

ABSTRACT
Gregory v. Helvering is a landmark case in the area of corporate reorganizations. The concepts that evolved from Gregory include the business purpose test, continuity of business, the taxpayer's right to minimize tax liability, step transaction doctrine, and the economic substance doctrine. The Treasury Department sought a codification of the economic substance doctrine as a necessary weapon to curb the growth of corporate tax shelters. While the doctrine had been part of the fabric of our tax system since Gregory, it had been eroded by some confusing and conflicting case law. In 2010 (the 75th anniversary of Gregory), Congress codified the economic substance rules. In order to understand this new legislation it is necessary to explore the long and grand history of the Gregory case as a backdrop for consideration of the merits and demerits of the codification of the economic substance doctrine.
Spontaneous regression of lumbar Hansen type 1 disk extrusion detected with magnetic resonance imaging in a dog
Authors: Steffen Frank , Kircher Patrick R. , Dennler Matthias 
Published: February 2014

Abstract
Case Description—A 3-year-old French Bulldog was evaluated because of acute signs of back pain and spastic paraparesis.
Clinical Findings—Neuroanatomic localization indicated a lesion in the T3-L3 spinal cord segment. Magnetic resonance imaging revealed extradural spinal cord compression at the ventral right aspect of the intervertebral disk space L3–4. On the basis of these findings, a diagnosis of sequestrated Hansen type 1 disk extrusion without extradural hemorrhage was made.
Treatment and Outcome—The dog was treated conservatively with cage rest, restricted exercise on a leash, and NSAIDs. Results of follow-up examination 5 weeks later indicated complete resolution of clinical signs, and results of repeated MRI indicated a 69% reduction in the volume of the herniated disk material.
Clinical Relevance—Findings for the dog of this report indicated spinal cord compression attributable to extruded intervertebral disk material resolved. Functional improvements in dogs with such problems may be partly attributable to spontaneous regression of intervertebral disk extrusions.
Spectrin and phospholipids — the current picture of their fascinating interplay

Published: February 2014

AbstractThe spectrin-based membrane skeleton is crucial for the mechanical stability and resilience of erythrocytes. It mainly contributes to membrane integrity, protein organization and trafficking. Two transmembrane protein macro-complexes that are linked together by spectrin tetramers play a crucial role in attaching the membrane skeleton to the cell membrane, but they are not exclusive. Considerable experimental data have shown that direct interactions between spectrin and membrane lipids are important for cell membrane cohesion. Spectrin is a multidomain, multifunctional protein with several distinctive structural regions, including lipid-binding sites within CH tandem domains, a PH domain, and triple helical segments, which are excellent examples of ligand specificity hidden in a regular repetitive structure, as recently shown for the ankyrin-sensitive lipid-binding domain of beta spectrin. In this review, we summarize the state of knowledge about interactions between spectrin and membrane lipids.

Published: February 2014

AbstractThe metazoan parasite assemblage of the head of 30 specimens of the Atlantic chub mackerel (Scomber colias) from the western Mediterranean Sea was analysed. Eight species of parasites were found, four mazocraeid monogeneans: Grubea cochlear (prevalence = 10%), Kuhnia scombercolias (59%), K. scombri (52%), Pseudokuhnia minor (86%); three didymozoid trematodes: Nematobothrium cf. faciale (21%), N. filiforme (41%), N. scombri (7%); and one laerneopodid copepod: Clavelissa scombri (7%). Results were compared with previously published data from 14 localities of the eastern Mediterranean Sea and the Atlantic Ocean, using non-parametric univariate and multivariate analyses, and the whole parasite fauna of S. colias was compared with that of the congeners (S. australasicus, S. japonicus and S. scombrus). Parasites showed to reflect the biogeographical and phylogenetic history of host. From a methodological point of view, the use of both non-parametric univariate and multivariate techniques proved to be effective tools to detect dissimilarities between parasite assemblages.
Larval trematodes infecting the South-American intertidal mud snail Heleobia australis (Rissooidea: Cochliopidae)
Authors: Alda Pilar , Martorelli Sergio 
Published: February 2014

AbstractLarval trematodes infecting the snail Heleobia australis (Cochliopidae) from the Bahía Blanca estuary, Argentina were surveyed for two years. A total of 7,504 snail specimens was dissected and the larval stages of 15 different trematodes were recovered and examined morphologically. These larvae included four species that had previously been reported from H. australis in Brazil, Uruguay, and Argentina: the heterophyid Ascocotyle (Phagicola) longa and the microphallids, Maritrema bonaerense, Maritrema orensense, and Microphallus simillimus. Three other species, the echinostomatid Stephanoprora uruguayensis, the microphallid Levinseniella cruzi, and the psilostomid Psilochasmus oxyurus are reported here for the first time as parasites of H. australis. Eight other trematodes found in H. australis are described and placed in the appropriate superfamilies, families or genera (Cryptogonimidae, Apocreadiidae, Aporocotylidae, Notocotylidae, Haploporidae, Renicolidae, Himasthla, and Renicola). The prevalence of the trematode taxa infecting H. australis in the Bahía Blanca estuary was low (<3%) with a single exception (M. simillimus; >20%). Microphallidae were the richest and the most prevalent family, probably because of the high abundance of crabs — the second-intermediate hosts of certain microphallid species — and the considerable diversity of gulls. Here we compare the parasite assemblage found in the H. australis from Bahía Blanca estuary with other parasite assemblages infecting Heleobia spp. and other rissooids from the rest of the world.

Published: February 2014

AbstractMonitoring parasitic infections in the red fox is essential for obtaining baseline knowledge on the spread of diseases of veterinary and medical importance. In this study, screening for cardiopulmonary and intestinal helminths and sarcoptic mange (Sarcoptes scabiei) was done on 118 foxes originating from two distinct localities in Denmark, (Copenhagen) greater area and southern Jutland. Fifteen parasite species were recorded in 116 foxes (98.3%), nine parasitic species are of zoonotic potential. Parasite diversity was greater in foxes of Copenhagen in terms of overall parasite species richness and species richness of all helminth groups individually: trematodes; cestodes; and nematodes. Six parasite species were recovered from foxes of Copenhagen, but not from foxes of Southern Jutland: Echinochasmus perfoliatus; Echinostoma sp.; Pseudamphistomum truncatum; Dipylidium caninum; Angiostrongylus vasorum; and Sarcoptes scabiei, but Toxascaris leonina was only recorded in foxes of southern Jutland. A high prevalence and abundance of A. vasorum in foxes of Copenhagen was observed. The prevalence of four nematode species; Eucoleus (Capillaria) aerophilus, Uncinaria stenocephala, Toxocara canis, and Crenosoma vulpis, in foxes of both localities were comparable and ranging from 22.9% to 89%. The prevalence of Mesocestoides sp. was significantly higher in foxes of Copenhagen. Taenia spp. were detected using morphological and molecular analysis, which revealed the dominance of T. polyacantha in foxes of both localities. Infections with sarcoptic mange were evident only among foxes of Copenhagen (44.9%), which significantly affected the average weight of the infected animals. Further remarks on the zoonotic and veterinary implications of the parasites recovered are given.
Parasites communities in the clingfish Gobiesox marmoratus from central Chile
Authors: Muñoz Gabriela 
Published: February 2014

AbstractThis study investigated the factors (i.e., season, locality, sampling year, total length and maturity stage of the hosts) that might influence the structure of parasite populations and communities in the clingfish Gobiesox marmoratus. The parasite community was described and analyzed using numerical descriptors, such as prevalence, intensity and species richness, between factors previously mentioned. A total of 260 clingfish were collected from 2 localities of central Chile, four seasons and during 3 year cycles (from July 2006 to July 2009). In the whole clingfish sample, 668 parasites were found, which belonged to 14 parasite taxa; 9 of them were new records in G. marmoratus. Parasite infracommunity richness ranged 0–3 species, although 1 trematode species, Helicometrina nimia, represented 80% of all parasites collected and was the most abundant and prevalent parasite species. The average of parasite abundance and intensity (± SD) was 2.5 ± 8.2 and 7.5 ± 12.7, respectively. Generalized linear model showed that parasite communities were influenced by season, locality, sampling year, and maturity stage when considering the abundance and intensity of parasites. For the parasite richness, only the locality and maturity of fish was determinant for explaining the differences. The populations and communities of the parasite variations were variable due to differences in fish body length because prevalence, abundance and intensity of parasites significantly correlated with the fish body length. Concordantly, maturity fish were longer than immature fish. Thus, clingfish from El Tabo were longest and mature, which harbored higher parasite richness than those fish from Las Cruces.
Oral inoculation of live or dead third-stage larvae of Anisakis simplex in rats suggests that only live larvae induce production of antibody specific to A. simplex
Authors: Abe Niichiro , Teramoto Isao 
Published: February 2014

AbstractLive Anisakis simplex third-stage larvae (L3) penetrate gastrointestinal mucosa after they are ingested in raw or undercooked seafood, thereafter causing gastrointestinal manifestations and allergic manifestations such as urticaria and anaphylaxis. These allergic reactions are mediated by specific IgE to L3 allergens, especially excretory-secretory (ES) allergens. Recent evidences suggest that only live larvae can cause allergic reactions, although cases attributable to ingestion of cooked, frozen seafood have been reported. Therefore the risk of Anisakis-associated hypersensitivity by ingestion of properly cooked and frozen fish remains controversial. No prior report describes the kinetics of antibody production in experimental animals after oral inoculation with dead L3. This study used ELISA to assess antibody production in rats inoculated orally with dead L3. Positive absorbance value in IgG, IgM, and IgE specific to ES antigen from L3 were found in rats inoculated with live L3 but not with dead L3 (frozen, heated, cut, or homogenized). At one week post re-inoculation with live or frozen L3 to the initially sensitized rats, the absorbance value of the specific IgM and IgE to ES antigen elevated quickly and highly in rats that had been re-inoculated with live L3, but they decreased slightly or did not change in rats inoculated with frozen L3. These results suggest that only ingestion of live L3 can produce the specific antibody and induce initial and secondary sensitizations to L3.
New species of Orientatractis (Nematoda: Atractidae), new species of Rondonia (Nematoda: Atractidae) and other helminths in Austrochaperina basipalmata (Anura: Microhylidae) from Papua New Guinea
Authors: Bursey Charles , Goldberg Stephen , Kraus Fred 
Published: February 2014

AbstractTwo new nematode species, Orientatractis hamabatrachos sp. nov. and Rondonia batrachogena sp. nov. (Nematoda: Atractidae), from the gastrointestinal tract of Austrochaperina basipalmata (Anura: Microhylidae) collected in Papua New Guinea are described. Orientatractis hamabatrachos sp. nov. is characterized by the presence of the cephalic end armed with 4 wellsclerotized structures, consisting of 2 “horns” extending outward and downward and immediately below a single well-sclerotized spine. It differs from 5 congeners in spicule lengths and caudal papillae arrangements. Rondonia batrachogena sp. nov. is characterized by the presence of a female cloaca. It differs from 2 congeners primarily in body size. Orientatractis hamabatrachos sp. nov. and Rondonia batrachogena sp. nov. represent the first species assigned to either genus found to infect anurans or to occur in the Australo-Papuan region.

AbstractThe adaptation and immunogenisity of Cryptosporidium parvum isolated from Siberian chipmunks (SC1 strain) in immunocompetent (ICR) mice were examined. The oocysts were received to the severe combined immunodeficiency (SCID) mice by repeated passage. The oocysts collected from the 18th SCID mice were inoculated to 5 ICR mice. The mice began to shed oocysts from 6 days after inoculation, the patency was 5 days, and the maximum oocysts per gram of feces (OPG) value was 104. The maximum of OPG value was gradually increased by successive passage, and finally that in the 22nd mice reached 106 (patency: 11 days). It is considered that these results indicate completion of their adaptation to ICR mice. To examine the immunogenicity of C. parvum to ICR mice, 8 groups of 5 mice each were inoculated with 1.3 × 106 oocysts of SC1 strain, which were collected after adaptation to SCID mice. All groups shed oocysts from 6th day, and their patency was from 8 to 12 days. On the 21st day after the primary infection, these mice were challenged with 1.3 × 106 oocysts. No oocysts shed from any groups, although 2 control groups shed oocysts from the 6th day, and their OPG values were more than 106. These results suggest that this strain has strong immunogenicity against ICR mice. Therefore, the immunological healthy mice were considered a useful experimental model to investigate immunological and drug treatments in the strain of C. parvum.
Molecular analysis of lungworms from European bison (Bison bonasus) on the basis of small subunit ribosomal RNA gene (SSU)
Authors: Pyziel Anna 
Published: February 2014

AbstractDictyocaulosis (Nematoda: Trichostrongyloidea) is a widespread parasitosis of the European bison (Bison bonasus) inhabiting Bialowieza Primeval Forest. Bearing in mind the current coexistence of bison with wild cervids, and with domestic ruminants in the 19th and 20th century, the need arose for molecular identification of lungworm species. Molecular analysis was done on adult lungworms that were obtained from the respiratory track of four free-roaming bison euthanized as a part of the population health control program. As the result of the study four identical small subunit-ribosomal RNA gene sequences from the lungworms were obtained and deposited in GenBank as sequence, 1708 bp long (GenBank KC771250). Comparative analysis of the SSU rRNA sequences revealed the European bison to be a host for the bovine lungworm Dictyocaulus viviparus.

AbstractIn the present study 5 grey seals (Halichoerus grypus), 3 common seals (Phoca vitulina) and 1 ringed seal (Pusa hispida) bycaught or stranded on the Polish Baltic Sea coast in years 2000-2006 were investigated for the infestation of parasitic anisakid nematodes. 749 of anisakids were found. The most common were: Contracaecum osculatum (59.3%) and Pseudoterranova decipiens (31.0%). There were also small numbers of Anisakis simplex (0.8%). After performing RFLP three sibling species were found. C. osculatum was identified as C. osculatum C, P decipiens was identified as P. decipiens sensu stricto and A. simplex — A. simplex sensu stricto. Nematodes found in seals were mostly in L4 and adult life stage — both of them were equal with some minor variations among the specimens. Sex ratio was also equal, but there was slight excess of males in some cases. There was a minority of L3 larvae belonging to A. simplex species (0.8%).
