Am J Ophthalmol Case Rep 2021 Sep 14;23:101111. Epub 2021 May 14.

Department of Ophthalmology, Byers Eye Institute, Stanford University School of Medicine, Palo Alto, CA, USA.

Purpose: To study post-interventional findings in patients with dysthyroid optic neuropathy (DON) treated with teprotumumab.

Integrating Patient Reported Outcome Measures (PROMs) into routine nurse-led primary care for patients with multimorbidity: a feasibility and acceptability study.

Health Qual Life Outcomes 2021 Apr 26;19(1):133. Epub 2021 Apr 26.

Health Services and Policy Research, Exeter Collaboration for Academic Primary Care (APEx), University of Exeter, Magdalen Campus, Smeall Building, Room JS02, Exeter, EX1 2LU, UK.

Background: The use of Patient Reported Outcome Measures (PROMS) in clinical practice has the potential to promote patient-centred care and improve patients' quality of life. Individualized PROMs may be particularly helpful in identifying, prioritizing and monitoring health problems of patients with multimorbidity. We aimed to develop an intervention centred around PROMs feedback as part of Primary Care annual reviews for patients with multimorbidity and evaluate its feasibility and acceptability. Read More

Biology (Basel) 2021 Jan 10;10(1). Epub 2021 Jan 10.

Department of Endodontology, The Goldschleger School of Dental Medicine, Tel Aviv University, Tel Aviv 69978, Israel.

This clinical trial focused on collating the instrumentation time and quality of root canal obturation in primary molars treated with three instrumentation techniques: adaptive, rotary, and manual. A triple-armed, randomized controlled clinical trial was performed on 75 primary molars requiring pulpectomy treatment, divided into three groups ( = 25 per group). The teeth in Group 1 were instrumented with an adaptive technique (XP-endo Shaper, FKG Dentaire, La Chaux-de-Fonds, Switzerland), Group 2 with pediatric rotary files (Kedo-S; D1 and E1), and Group 3 with a manual technique (hand K-files).

Apical extrusion of debris with different rotary and reciprocating single-file endodontic instrumentation systems: a systematic review and meta-analysis protocol.

BMJ Open 2020 09 14;10(9):e038502. Epub 2020 Sep 14.

Department of Conservative Sciences, College of Dentistry, Qassim University, Buraydha, Saudi Arabia.

Outcomes of a Telephone-Based Questionnaire for Follow-up of Patients Who Have Completed Curative-Intent Treatment for Oral Cancers.

JAMA Otolaryngol Head Neck Surg 2020 12;146(12):1102-1108

Department of Head & Neck Oncology, Tata Memorial Centre, Homi Bhabha National Institute, Mumbai, India.

Importance: Follow-up assessment of patients who had treatment for head and neck cancer is critical and an important part of the overall treatment program. During each visit to the hospital, patients are evaluated by a physician and may undergo additional tests. Because it has been observed that the symptoms mentioned by patients often guide the treating clinicians in identifying cancer recurrence, an appropriately constructed questionnaire can help clinicians determine which patients need further testing as a result of a recurrence and which patients can continue to be monitored remotely.

Improving the Efficacy of the Data Entry Process for Clinical Research With a Natural Language Processing-Driven Medical Information Extraction System: Quantitative Field Research.

JMIR Med Inform 2019 Jul 16;7(3):e13331. Epub 2019 Jul 16.

Pediatric Translational Medicine Institute, Shanghai Children's Medical Center, Shanghai Jiao Tong University School of Medicine, Shanghai, China.

Background: The growing interest in observational trials using patient data from electronic medical records poses challenges to both efficiency and quality of clinical data collection and management. Even with the help of electronic data capture systems and electronic case report forms (eCRFs), the manual data entry process followed by chart review is still time consuming.

Objective: To facilitate the data entry process, we developed a natural language processing-driven medical information extraction system (NLP-MIES) based on the i2b2 reference standard. Read More

Status of Mandibular Third Molar Development as Evidence in Legal Age Threshold Cases.

J Forensic Sci 2019 May 8;64(3):680-697. Epub 2018 Oct 8.

Institute of Dentistry, Barts and the London School of Medicine and Dentistry, Queen Mary University of London, London, E1 2AD, U.K.

The completion of the third molar roots has played an important role in ascertaining whether individuals may be at or over a legal threshold of age, often taken as 18 years. This study demonstrates that root apex completion in the third molar is relatively uninformative regarding the threshold of age 18 years in a sample of 1184 males, where mean age-of-attainment of root apex completion for third mandibular molars is about 19.4 years.

Clinical Findings of a Cantilever Iliac Bone Graft for Secondary Correction of Cleft Lip-Nose Deformities.

J Craniofac Surg 2018 May;29(3):741-746

Department of Oral-Maxillofacial Surgery, University of Tokyo Hospital, Tokyo.

The authors performed a cantilever iliac bone graft for the secondary correction of severe cleft lip-nose deformities after the completion of growth. For the purpose of clarifying effects of the cantilever iliac bone grafts and the adverse events with regard to their time course changes after this procedure, the authors retrospectively surveyed long-term morphologic changes in 65 cleft lip, alveolus, and palate patients in whom cleft lip-nose deformities were treated with a cantilever iliac bone graft (age at surgery: 14-45 years old). All postsurgical documents of facial photographs and radiologic images were reviewed to evaluate the effects and adverse events. Read More

Intracranial Ewing sarcoma: four pediatric examples.

Childs Nerv Syst 2018 03 28;34(3):441-448. Epub 2017 Dec 28.

Department of Neurosurgery, The University of Colorado School of Medicine, 12605 E. 16th Avenue, Aurora, CO, 80045, USA.

Background: Ewing sarcoma typically arises in bone and is unrelated to intraparenchymal small blue cell embryonal central nervous system (CNS) tumors previously designated primitive neuroectodermal tumors (PNETs). When the CNS is impacted, it is usually secondary to local extension from either the epidural space, skull, or intracranial or spinal metastases. Primary examples within the cranial vault are rare, usually dural-based, and are largely case reports in the literature. Read More

Oil sands tailings pond sediment toxicity to early life stages of northern pike (Esox lucius).

Sci Total Environ 2018 May 19;624:567-575. Epub 2017 Dec 19.

Environment and Climate Change Canada, 867 Lakeshore Road, Burlington, ON L7S 1A1, Canada.

The Athabasca River in Alberta flows through natural sources of eroding oil sands bitumen and oil sands mining operations that may result in low level contamination of surface waters. Northern pike (Esox lucius) are apex predators and important food and game fish species native to the Athabasca River system. This species has the potential to be exposed to both natural and anthropogenic sources of contamination from oil sands related materials throughout its life cycle. Read More

Sexual reproduction in plagiogrammacean diatoms: First insights into the early pennates.

PLoS One 2017 16;12(8):e0181413. Epub 2017 Aug 16.

Institut de biologie intégrative et des systèmes, Université Laval, Québec, Québec, Canada.

The genera Plagiogramma and Dimeregramma are members of a small, but evolutionarily important group of diatoms, the "basal" araphids. They are sister to all other pennates, both araphid and raphid taxa. Thus, their phylogenetic position carries the potential for providing insights into the earliest pennates. Read More
