Deficits in Explicit Language Problem Solving Rather Than in Implicit Learning in Specific Language Impairment: Evidence From Learning an Artificial Morphological Rule
Authors: Ferman Sara , Kishon-Rabin Liat , Ganot-Budaga Hila , Karni Avi 
Published: September 2019

Purpose
The purpose of this study was to delineate differences between children with specific language impairment (SLI), typical age–matched (TAM) children, and typical younger (TY) children in learning and mastering an undisclosed artificial morphological rule (AMR) through exposure and usage.

Method
Twenty-six participants (eight 10-year-old children with SLI, 8 TAM children, and ten 8-year-old TY children) were trained to master an AMR across multiple training sessions. The AMR required a phonological transformation of verbs depending on a semantic distinction: whether the preceding noun was animate or inanimate. All participants practiced the application of the AMR to repeated and new (generalization) items, via judgment and production tasks.

Results
The children with SLI derived significantly less benefit from practice than their peers in learning most aspects of the AMR, even exhibiting smaller gains compared to the TY group in some aspects. Children with SLI benefited less than TAM and even TY children from training to judge and produce repeated items of the AMR. Nevertheless, despite a significant disadvantage in baseline performance, the rate at which they mastered the task-specific phonological regularities was as robust as that of their peers. On the other hand, like 8-year-olds, only half of the SLI group succeeded in uncovering the nature of the AMR and, consequently, in generalizing it to new items.

Conclusions
Children with SLI were able to learn language aspects that rely on implicit, procedural learning, but experienced difficulties in learning aspects that relied on the explicit uncovering of the semantic principle of the AMR. The results suggest that some of the difficulties experienced by children with SLI when learning a complex language regularity cannot be accounted for by a broad, language-related, procedural memory disability. Rather, a deficit—perhaps a developmental delay in the ability to recruit and solve language problems and establish explicit knowledge regarding a language task—can better explain their difficulties in language learning.

Published: September 2019

Context.The study of noble gas compounds has gained renewed interest thanks to the recent detection of ArH+in the interstellar medium (ISM). The analysis of physical-chemical conditions in the regions of the ISM where ArH+is observed requires accurate collisional data of ArH+with He, H2, electrons, and H.Aims.The main goals of this work are to compute the first three-dimensional potential energy surface (PES) to study the interaction of ArH+with He, analyze the influence of the isotopic effects in the rate coefficients, and evaluate the rovibrational relaxation rates.Methods.Two ab initio grids of energy were computed at the coupled cluster with single, double, and perturbative triple excitations (CCSD(T)) level of theory using the augmented correlation consistent polarized quadruple, and quintuple zeta basis sets (aug-cc-pVQZ, and aug-cc-pV5Z) and a grid at the complete basis set limit was determined. The analytical representation of the PES was performed using the reproducing kernel Hilbert space (RKHS). The dynamics of the system was studied using the close coupling method.Results.The differences in the rate coefficients for the isotopes36ArH+,38ArH+, and40ArH+in collision with He are negligible. However, the rotational rates for the collision of ArD+with He cannot be estimated from those for ArH++He. Comparison with previous rates for the36ArH++He collision showed discrepancies for ∣ Δj ∣ > 2, and in the case of high initial rotational states of36ArH+differences were found even for ∣ Δj ∣ = 1. The rates for transitions between different vibrational states were also examined. Finally, new sets of rotational rates for36ArH++He and36ArD++He are reported.
Ernährung bei Gewichtsverlust – Vitalität stärken mit Genuss
Authors: Weis Nicole , Bihlmaier Susanne 
Published: September 2019

ZusammenfassungEs gibt zunehmend Evidenz, dass bei Krebspatient*innen während und nach der Krebstherapie einem zu starken Gewichtsverlust vorzubeugen ist. Welche Maßnahmen im Sinne der Sekundärprävention zu empfehlen sind, hängt stark vom Einzelfall und der vorliegenden Tumorerkrankung ab. Bei hormonabhängigen Tumoren, wie zum Beispiel Brustkrebs, ist bei adipösen Patientinnen nach erfolgter Primärtherapie eine Gewichtsreduktion sinnvoll. Unter stark belastenden Therapien und bei fortgeschrittener Tumorerkrankung hingegen sind die wichtigsten Ziele das Halten des Gewichts bzw. der Gewichtsaufbau. Gesundheitliche Beschwerden, die die Nahrungsaufnahme zusätzlich beeinträchtigen, sollten so früh wie möglich gelindert werden. Komplementärmedizinische Möglichkeiten werden anhand der Mukositis erläutert.

Zusammenfassung
Einleitung Die kardialen Troponine sind die bevorzugten kardialen Biomarker in der Diagnostik eines akuten Myokardinfarkts. Sie sind jedoch bei jeglichen Myokardzellschäden, egal welcher Pathophysiologie, nachweisbar. Das Ziel dieser Studie ist, zu beurteilen, wie die Gütekriterien des Troponin-Tests in der Diagnose des akuten Myokardinfarkts im Alltag sind und ob klinische Leitsymptome einen Einfluss darauf haben.
Methode Es handelt sich um eine retrospektive Querschnittsstudie, in welche alle Patienten, die sich in der Notaufnahme des Klinikums Lippe-Detmold zwischen dem 01.01.2014 und dem 31.05.2014 vorstellten und einen Troponin-Test hatten, eingeschlossen wurden. Die Diagnose akuter Myokardinfarkt bezog sich auf den Myokardinfarkt Typ I und wurde durch den diensthabenden Kardiologen gestellt. Die Patienten wurden in 4 Subgruppen entsprechend der Leitsymptome unterteilt. Die Gütekriterien des Troponin-Tests wurden berechnet.
Ergebnisse 1046 Patienten wurden eingeschlossen. Bei 15 % lag ein akuter Myokardinfarkt vor, 97 % von diesen hatten thorakale Schmerzen. Die Sensitivitäten und die negativen prädiktiven Werte lagen über 90 %. Die Spezifitäten lagen zwischen 56 % und 81 %. Die positiven prädiktiven Werte waren bescheiden und am besten bei den thorakalen Schmerzen mit 58 %.
Schlussfolgerung Bei allen klinischen Leitsymptomen hatte der Troponin-Test einen guten negativen prädiktiven Wert. Ein akuter Myokardinfarkt konnte somit mit hoher Präzision ausgeschlossen werden. Der positive prädiktive Wert war hingegen niedrig. Lediglich bei dem Leitsymptom Thoraxschmerz konnten akzeptable Werte erreicht werden.

Published: September 2019

ResumoA porfiria aguda intermitente é uma doença genética rara, autossômica dominante, com penetrância variável, que ocasiona erro no metabolismo hepático da via do heme, com acúmulo de intermediários tóxicos ao organismo. Manifesta-se por crises de sintomatologia multissistêmica com diagnóstico muitas vezes difícil. Os achados principais são dor abdominal intensa, polineuropatia motora, disautonomia, e distúrbios neuropsiquiátricos. Varia de quadros leves a muito graves, com arritmia maligna e paralisia bulbar, e às vezes com insuficiência ventilatória, que causa necessidade de ventilação mecânica e internação em unidade de terapia intensiva. A confirmação diagnóstica é bioquímica e genética. O tratamento da crise é feito afastando-se fatores precipitantes e especificamente com dieta rica em carbohidratos e hematina, com efeito positivo na via de biossíntese do heme. Dentro da equipe multidisciplinar, sobressai o papel do médico nutrólogo, que avalia e orienta a terapia nutrológica, tanto nas crises como no acompanhamento ambulatorial desses pacientes.

Published: September 2019

ABSTRACTSinus floor augmentation (SFA) is one of the techniques that has been proposed for improving the long-term retention of dental implants. The procedure involves the creation of a submucoperiosteal pocket in the floor of the maxillary sinus for placement of a graft consisting of autogenous, allogenic, or alloplastic material. Complications of the SFA predominantly consist of disturbed wound healing, hematoma, sequestration of bone, and transient maxillary sinusitis. In this report, we presented an acute maxillary sinusitis complication following internal sinus lifting in a patient with chronic maxillary sinusitis. (Eur J Dent 2008;2:69-72)

ABSTRACTObjectives: The aim of this study was to investigate the effects of fiber-reinforced resin burs on
the surface roughness of a nanofilled composite.Methods: Average surface roughness values (Ra, �m) were measured using a surface profilometer and surface textures after finishing procedures were evaluated using a scanning electron microscope (SEM). Thirty cylindrical specimens were prepared using sectional teflon molds. A nanofilled composite was chosen. After the preparation specimens were divided into three subgroups randomly. After profilometric measurements, representative samples of the mentioned finishing procedures were selected and SEM analyses were carried out.Results: Mylar strip group was statistically different from the other two groups (P<.05). The smoothest surfaces occurred when composite resin samples were light cured against the strips. On the other hand there was no statistical difference between fiber-reinforced resin burs and Sof-Lex discs (P>.05). For fiber-reinforced resin burs scratches and pitting which may be due to plucking of
the filler particles during finishing were observed on the surface topography of the composite resin material. On the other hand, for the Sof-Lex discs although scratches were noticed on the surface topography, no pitting was observed.Conclusions: Fiber-reinforced resin burs can be preferred for the grinding of composite surplus
in interproximal surfaces, where the use of Sof-Lex discs can be harmful to soft tissues. (Eur J Dent

Published: September 2019

ABSTRACTObjectives: The primary goal of prosthetic obturation is closure of the maxillectomy defect and separation of the oral cavity from the sino-nasal cavities by use of different bulb designs. The aim of this study was to evaluate the articulation performance of obturator patients with three different buccal extension designs.Methods: Five patients with palatal defects of comparable sizes at ages ranging from 42 to 74 were evaluated. Starting at postoperative 4 months, speech intelligibility (SI) was assessed without a prosthetic obturator and with an obturator of buccal extensions 15 mm (high), 10 mm (medium) and 5 mm (low), respectively. Assessments were performed at four week intervals for adaptation. The articulation performance of patients with different buccal extension designs were evaluated on speech intelligibility. The data tested using Friedman test.Results: The mean SI score without an obturator was 45.04%±5.86%. SI was found to be significantly increased with obturators of any buccal extensions with the mean values 90.50, %94.24% and 91.20% for high, medium, and low buccal extensions respectively. When the SI score was compared between three buccal extension types medium was found to be significantly higher compared to others (P<.05).Conclusions: Obturators improve speech intelligibility irrespective of their buccal extension levels. Nevertheless, medium size buccal extension enables the optimum sealing for better articulation. (Eur J Dent 2009;3:185-190)

Published: September 2019

ABSTRACTGeminated teeth are the consequences of developmental anomalies leading to the eruption of joined elements. According to current definitions, gemination occurs when one tooth bud tries to divide, while fusion occurs if two buds unite. Clinical experience shows, however that diagnosis can be complicated due to superimposed anomalies. This report describes a unique case of bilateral gemination of permanent maxillary central incisors. The esthetic rehabilitation of the geminated incisors accomplished utilizing all ceramic crowns. It is important that in these types of cases, reaching to the available esthetics and avoiding the complication of caries and periodontal problems with prosthetic application is satisfactory.

ABSTRACTSubmerged primary molars can be difficult to manage due to the developing dentition. Rarely in some severe cases, may the surgical interventions be required while ensuring the vital structures are protected. Therefore these cases require sophisticated imaging techniques in order to locate the vital structuresIn this case report, a 17 year old girl who had a retained and submerged deciduous molar which caused impaction of the second premolar and tipping of the first molar was presented. In addition, value of computed tomography (CT) for locating the vital anatomic structures was discussedIn our case, CT has been supplied effective information about localization of the vital structures and amount of bone volume during the diagnosis and treatment planning period in addition to the routine dental radiographies.

Published: September 2019

ABSTRACTAcute streptococcal gingivitis is an acute inflammation of the oral mucosa and also may be seen with the other oral diseases as aggressive periodontitis that is characterized by a considerable attachment loss over a relatively short period of time. Streptococcal infections of gingiva are seen rarely; also the origin of this gingival inflammation is occasionally different from that of routine plaque-associated gingivitis. The clinical features and treatment methods of these diseases are already reported in previous literatures. This case report describes a patient who presented with severe gingival inflammation and attachment loss that was diagnosed as an acute streptococcal infection associated with aggressive periodontitis. In this study a supportive treatment option was demonstrated based on these data and antacid treatment as adjunctive to the recommended treatment modalities was used for streptococcal gingivitis.

Published: September 2019

ABSTRACT
Background and objectives: Bleeding from hemorrhoids is the commonest cause of rectal bleeding in adults. Injection sclerotherapy of internal hemorrhoids is one of the non-surgical treatments, and is simple, safe and feasible. Conventionally sclerotherapy is performed with rigid proctoscope which has limitations of maneuverability, narrower field of vision and documentation compared to flexible videoendoscope. Therefore, we assessed the efficacy and safety of video-colonoscopic sclerotherapy for bleeding internal hemorrhides.
Methods: Seventy-nine patients of bleeding internal hemorrhoids were subjected to colonoscopic sclerotherapy using 1.5% polidocanol in retroflexed or forward viewing positions. Success of treatment was defined as cessation of bleeding for six weeks. Patients were observed for complications and were followed up regularly for 3 months.
Results: A total of 79 evaluable patients, 61 had grade II and 18 had grade III hemorrhoids. There was no statistically significant differences in achieving excellent or good results for control of bleeding between patients with grade II and grade III hemorrhoids (100% vs 94,5%; p>0.05). The number of sessions of sclerotherapy required were significantly more in grade II than grade III hemorrhoids (1.1 ± 0.3 vs 1.3 ± 0.7; p = 0.04). No significant complications were noted except for bloating in ten patients (12.6 %) and rectal pain in 6 (7.6%) patients. Median time taken for the procedure was 30 minutes.
Conclusions: Video-endoscopic sclerotherapy is safe, well-tolerated and effective treatment for bleeding internal hemorrhoids.(J Dig Endosc 2011;2(1):1-5)

ABSTRACT
Background and objectives: Proton pump inhibitors are used widely for gastroesophageal reflux disease and ulcer type dyspepsia. Majority of the patients require long term medication. H2 receptor antagonist are also used for relief of symptoms. Though tachyphylaxis has been reported, symptom response is seen with long term use. The aim of the present study was to study the effects of long-term acid suppressants on gastric antral histology.
Methods: Patients who received long-term acid suppressants such as ranitidine and omeprazole for gastroesophageal reflux disease or dyspepsia were included. All of them had an antral biopsy for histology and H. pylori status at baseline, at 6 months and 12 months. Patients on acid suppressants for less than a year or on long-term non-steroidal anti inflammatory drugs were excluded from the study. The grading of gastritis was classified as chronic active gastritis, atrophic gastritis, intestinal metaplasia and dysplasia.
Results: Thirty patients received ranitidine and 28 omeprazole. In H. pylori positive group, the median duration of ranitidine and omeprazole were 3 years (1.5 to 8 years) and 4 years (1 to 10 years) respectively. Two thirds of patients had chronic active gastritis (ranitidine: 35.5% omeprazole:26.6%); 10 had gastric atrophy (ranitidine: 6.6% omeprazole:15.5%) and 7 had intestinal metaplasia (ranitidine4.4% omeprazole11.1%). Four of the 10 patients on omeprazole showed progression of histology as against only one of the 13 patients on ranitidine at one year of follow up. In omeprazole pylori negative patients, the median duration of ranitidine and omeprazole was 2.5 years (range 1 to 6 years) and 3 years (range 2 to 7 years) respectively. Irrespective of the acid suppressants, the baseline histology was either chronic active gastritis (78.5%) or gastric atrophy (21.5%). None had intestinal metaplasia. Also there was no progression in histology staging during the follow up.
Conclusions: Long-term acid suppressants irrespective of the H. pylori status are not associated with significant histological changes in gastric mucosa. Despite a significant drop out of cases, among the cases followed up no significant progression in histological staging was seen during a one year follow-up. (J Dig Endosc 2013;4(1):1–5)

Published: September 2019

ABSTRACT
Background and objectives: Helicobacter pylori (H. pylori) are considered to be the most common human infectious agents leading to gastritis, ulcer and probably stomach cancer. The aim of this study was to evaluate the prevalence of H. pylori infection and histologic gastritis in Oman using endoscopy biopsy of the stomach.
Methods: A total of 366 stomach biopsies (171 males and 195 females) were histologically analyzed at Sultan Qaboos University Hospital, Muscat, Sultanate of Oman, between 2007 and 2010, using haematoxylin and eosin, Giemsa and Alcian blue / periodic acid-Schiff stains.
Results: Out of 366 cases, 110 (30.1%) were positive for H. pylori infection. Out of 110, 76 cases were associated with active chronic gastritis, 32 cases with chronic gastritis and one case each with gastric carcinoma and normal histological features. The maximum number of H. pylori organisms was found among young (26 – 44 years) and middle age (45 – 59 years) groups, 34.5% and 30.9%, respectively. H. pylori was present in 36.9% females and in 22.2% of males. 40.9% of H. pylori was found in the gastric antrum site, and the gastric cardia was free of H. pylori.

Conclusion: H. pylori associated active chronic gastritis is the most common form of stomach diseases encountered in this study. In addition, female, young and middle age group and gastric antrum had the highest frequency of H. pylori organisms. J Dig Endosc 2013;4(2):29-32)
