Association between malocclusion and orofacial myofunctional disorders of pre‐school children in Latvia
2019
Objects Abnormal use of muscles of tongue and lips is called orofacial myofunctional disorders (OMD). In this study, we aimed to investigate the interrelation between occlusal findings and OMD in primary and mixed dentition and to find out the reasons for malocclusions, and the effect modification of these associations by the number of sources that parents used to receive the information on child oral health issues (NSI). Setting and sample population Cross-sectional study was performed in one kindergarten in Latvia (cluster sampling). The study sample comprised 141 children-mothers' pairs of pre-school children aged 4-7 years. Materials and methods Children' myofunctional situation, occlus…
Oropharyngeal dysphagia in elderly population suffering from mild cognitive impairment and mild dementia: Understanding the link
2020
Abstract Purpose To evaluate the prevalence of oropharyngeal dysphagia in elderly patients suffering from minimal or mild cognitive decline. Patients and methods We retrospectively collected the data of patients suffering from mild cognitive impairment or mild dementia and were undergoing management for suspected oropharyngeal dysphagia, in our department. All our patients were subjected to Mini Mental State Examination test, MD Anderson dysphagia inventory and caregiver mealtime and dysphagia questionnaire. We performed a mealtime observation study and endoscopic evaluation of swallowing in all our patients. Following evaluation, we then analysed the data statistically. Results Out of 708 …
Swallowing evaluation with videofluoroscopy in the paediatric population
2017
Valutazione della funzione deglutitoria in videofluoroscopia nei pazienti pediatrici.I disturbi della deglutizione in età pediatrica possono essere dovuti a diverse cause, dalla condizione di prematurità e patologie malformative sino al reflusso gastro-esofageo o a patologie infettive od infiammatorie del primo tratto gastroenterico. Nei neonati il processo della deglutizione è involontario e basato su meccanismi riflessi. In seguito, nell’ infanzia, la fase orale diventa volontaria , mentre le fasi faringea ed esofagea rimangono involontarie. I disordini della deglutizione possono severamente compromettere le capacità respiratorie e l’apporto nutrizionale dei pazienti pediatrici. La videof…
Der Stellenwert der Sepsis nach Laparotomie im Kindesalter
1984
Laparotomy was performed on 579 children at the University Clinic of Paediatric Surgery in Mainz from 1.1.1975 to 31.12.1982. The children were up to 15 years of age; appendicitis or inguinal and umbilical hernia cases were not included. Postoperative sepsis occurred in 74 patients (12.8% of all children with laparotomy); in 51 cases positive bacteriological findings were seen besides the clinical and clinicochemical ones. Sepsis morbidity was particularly high in children who had not yet completed their first year of life (postoperative sepsis occurring in approximately every fourth infant); among the disease patterns, the following were particularly prominent: Defects of the abdominal wal…
Out-of-the-box pelvic surgery including iliopsoas resection for recurrent gynecological malignancies: Does that make sense? A single-institution case…
2017
Abstract Objective To report morbidity and oncological outcomes in a consecutive series of lateral isolated recurrent gynecological cancer involving the pelvic side wall (PSW) including the iliopsoas muscle. Material and methods We retrospectively evaluated a consecutive series between 6/2013 and 12/2015 of lateral isolated recurrent gynecological malignancies treated with a lateral endopelvic resection (LEPR). LEPR was defined as an en-bloc lateral resection of a pelvic tumor with sidewall muscle, and/or bone, and/or major nerve, and/or major vascular structure. Post-surgical complications, quality of life (QoL) and survivals were computed. Results Seventy-four women with pelvic isolated r…
Muscle activity in upper and lower rectus abdominus during abdominal exercises.
1996
Abstract Objective: To compare the intensity of the upper versus lower rectus abdominis (RA) muscle activity provoked by each of two different abdominal exercises and to contrast the intensity of contraction elicited by two different abdominal exercises on each RA muscle portion. Design: Nonrandomized control trial. Setting: Kinesiology laboratory in a university medicine faculty. Participants: Convenience sample of 33 healthy volunteers. Subjects who had practiced endurance or strength training activities (1.5 hours 3 days a week for 3 years) and those who had not accomplished that criterion comprised a high and a low physical activity group, respectively. Each of these two groups was divi…
Magnetization dynamics in polycrystalline Permalloy and epitaxial Co platelets observed by time-resolved photoemission electron microscopy
2009
We studied the dynamic magnetization response in rectangular polycrystalline Permalloy and also epitaxial Co structures (lateral sizes comprised tens of microns at a thickness of tens of nanometers) during the action of a magnetic field pulse, using time-resolved X-ray photoemission electron microscopy with a time resolution of 10 ps. In the case of Permalloy platelets the restoring torque that is necessary for the stroboscopic image acquisition is provided by the Landau flux closure structure representing a minimum of the free energy. We investigated the dynamic response of 90° Neel domain walls. The main results are: the maximum velocity of the domain wall is 1.5 × 104 m/s, the intrinsic …
Domain wall pinning in ultra-narrow electromigrated break junctions
2014
The study of magnetic domain walls in constrained geometries is an important topic, yet when dealing with extreme nanoscale magnetic systems artefacts can often dominate the measurements and obscure the effects of intrinsic magnetic origin. In this work we study the evolution of domain wall depinning in electromigrated ferromagnetic junctions which are both initially fabricated and subsequently tailored in-situ in clean ultra-high vacuum conditions. Carefully designed Ni(80)Fe(20) (Permalloy) notched half-ring structures are fabricated and investigated as a function of constriction width by tailoring the size of the contact using controlled in-situ electromigration. It is found that the dom…
Domain-wall induced large magnetoresistance effects at zero applied field in ballistic nanocontacts
2013
We determine magnetoresistance effects in stable and clean Permalloy nanocontacts of variable cross section, fabricated by UHV deposition and in situ electromigration. To ascertain the magnetoresistance (MR) effects originating from a magnetic domain wall, we measure the resistance values with and without such a wall at zero applied field. In the ballistic transport regime, the MR ratio reaches up to 50% and exhibits a previously unobserved sign change. Our results can be reproduced by recent atomistic calculations for different atomic configurations of the nanocontact, highlighting the importance of the detailed atomic arrangement for the MR effect.

Scaling of intrinsic domain wall magneto-resistance with confinement in electromigrated nanocontacts
2018
In this work we study the evolution of intrinsic domain wall magnetoresistance (DWMR) with domain wall confinement. Clean permalloy notched half-ring nanocontacts are fabricated using a special ultra-high vacuum electromigration procedure to tailor the size of the wire in-situ and through the resulting domain wall confinement we tailor the domain wall width from a few tens of nm down to a few nm. Through measurements of the dependence of the resistance with respect to the applied field direction we extract the contribution of a single domain wall to the MR of the device, as a function of the domain wall width in the confining potential at the notch. In this size range, an intrinsic positive…
