Survey on the radiology report at Chris Hani Baragwanath Academic Hospital: Clinician and radiologist perspectives.

Background: The radiology report is the primary means of conveying imaging findings between radiologists and clinicians. As a result, clinician satisfaction with the radiology report is an indicator of its quality and clinical relevance. It is crucial to identify factors that can enhance the radiology report in order to improve service delivery.

Diffusion-weighted imaging in addition to contrast-enhanced MRI in identifying complete response in HER2-positive breast cancer.

Objectives: The aim of this study is to investigate the added value of diffusion-weighted imaging (DWI) to dynamic-contrast enhanced (DCE)-MRI to identify a pathological complete response (pCR) in patients with HER2-positive breast cancer and radiological complete response (rCR).

Materials And Methods: This is a single-center observational study of 102 patients with stage I-III HER2-positive breast cancer and real-world documented rCR on DCE-MRI. Patients were treated between 2015 and 2019.

Breast DWI Analyzed Before and After Gadolinium Contrast Administration-An Intrapatient Analysis on 1.5 T and 3.0 T.

Objectives: Diffusion-weighted magnetic resonance imaging (MRI) is gaining popularity as an addition to standard dynamic contrast-enhanced breast MRI. Although adding diffusion-weighted imaging (DWI) to the standard protocol design would require increased scanning-time, implementation during the contrast-enhanced phase could offer a multiparametric MRI protocol without any additional scanning time. However, gadolinium within a region of interest (ROI) might affect assessments of DWI.

Predicting breast cancer types on and beyond molecular level in a multi-modal fashion.

Accurately determining the molecular subtypes of breast cancer is important for the prognosis of breast cancer patients and can guide treatment selection. In this study, we develop a deep learning-based model for predicting the molecular subtypes of breast cancer directly from the diagnostic mammography and ultrasound images. Multi-modal deep learning with intra- and inter-modality attention modules (MDL-IIA) is proposed to extract important relations between mammography and ultrasound for this task.

Habitat requirements of riparian arthropods on gravel bars: Implications for conservation and management of braided river floodplains.

In their pristine state, river landscapes consist of complex mosaics of aquatic and terrestrial habitats. They are highly dynamic and, with their harsh environments, offer living space for many specialists. In the present study, the habitat choice of specialists of the riparian arthropod community was studied on a near-natural stretch of the Upper Isar River.

Fatal non-accidental injury in South Africa: A Gauteng hospital's perspective on the incidence and fracture types in post-mortem skeletal surveys.

Background: In its severest form, non-accidental injury (NAI) in children is fatal. South Africa has been reported to have double the global average of child homicides. Autopsy is the main investigation in fatal NAI with post-mortem skeletal surveys (PMSS) playing an adjunctive role.

A randomized controlled trial comparing guided bone regeneration to connective tissue graft to re-establish buccal convexity at dental implant sites: Three-year results.

Objectives: To compare guided bone regeneration (GBR) to connective tissue graft (CTG) in terms of increase in buccal soft tissue profile (BSP) at three-year follow-up when applied at the buccal aspect of single implant sites demonstrating a minor horizontal alveolar defect.

Materials And Methods: Patients with a single tooth gap in the anterior maxilla and horizontal alveolar defect were enrolled in a single-blind RCT. All sites had a bucco-palatal bone dimension of at least 6 mm, received a single implant at least 3 months after tooth removal and were randomly allocated to the control (GBR) or test group (CTG) to re-establish buccal soft tissue convexity.

Soft tissue metric parameters, methods and aesthetic indices in implant dentistry: A critical review.

Objectives: The primary objective was to provide an overview of soft tissue metric parameters, methods, and aesthetic indices in implant dentistry. The secondary objective was to describe reliability and validity of aesthetic indices.

Materials And Methods: Two independent reviewers conducted an electronic literature search in Pubmed, Web of Science, Embase, and Cochrane databases up to October 2020 to identify studies on soft tissue metric parameters, methods, and aesthetic indices.

A 5 to 7-year case series on single angulated implants installed following papilla-sparing flap elevation.

Background: Bony concavities at the buccal aspect may cause a distortion between the implant axis and ideal prosthetic axis. Angulated implants can overcome this problem, yet long-term data are lacking. In addition, papilla-sparing incisions have been proposed to reduce tissue loss, yet aesthetic outcomes have not been published.

Analysis of patient safety risk management call data during the COVID-19 pandemic.

On March 11, 2020, the novel coronavirus disease, COVID-19, was declared a pandemic by the World Health Organization (WHO). The pandemic evolved rapidly, forcing providers to face previously unconsidered health care delivery scenarios. Medical and dental professionals sought guidance.

A 5-year cohort study on early implant placement with guided bone regeneration or alveolar ridge preservation with connective tissue graft.

Purpose: To assess on the one hand the 5-year outcome of early implant placement with guided bone regeneration (EIP/GBR) and on the other hand of alveolar ridge preservation with late implant placement and connective tissue graft (ARP/CTG).

Materials And Methods: Patients who had been treated with a single implant in the anterior maxilla in 2014 were selected for reevaluation in 2019. In the EIP/GBR cohort, implants were installed 4 to 8 weeks following extraction and the buccal contour was overbuilt by means of GBR.

Long-Term Follow-up on Root Coverage with a Double Pedicle Flap and Connective Tissue Graft.

Partial-thickness double pedicle flap and connective tissue graft (CTG) is a procedure to treat single gingival recession in the anterior mandible. However, long-term data have not been reported. Patients who had been treated by the same periodontist in a private practice in Belgium between 2002 and 2009 were invited to return for a clinical examination in 2017.

The 2017-19 activity at Mount Agung in Bali (Indonesia): Intense unrest, monitoring, crisis response, evacuation, and eruption.

After 53 years of quiescence, Mount Agung awoke in August 2017, with intense seismicity, measurable ground deformation, and thermal anomalies in the summit crater. Although the seismic unrest peaked in late September and early October, the volcano did not start erupting until 21 November. The most intense explosive eruptions with accompanying rapid lava effusion occurred between 25 and 29 November.

The Mucosal Scarring Index: reliability of a new composite index for assessing scarring following oral surgery.

Objectives: A critical and uniform assessment of mucosal scarring following oral surgery is needed to refine surgical decision-making. For that purpose, the Mucosal Scarring Index (MSI) was developed.

Materials And Methods: The MSI is a composite index based on five parameters: width, height/contour, color, suture marks, and overall appearance.

The RESET Mindset Model applied on decreasing antibiotic usage in dairy cattle in the Netherlands.

Background: Prudent use of antibiotics is important to prevent antibiotic resistance in humans and in animals. For this reason politicians demanded a decrease of total antibiotic use and of use of critically important antibiotics in animal husbandry in the Netherlands. In the dairy sector the use of antibiotics almost halved in the years 2009-2015, with a decrease of the use of critically important antibiotics to very low levels.

Experimental Evidence Shows the Importance of Behavioural Plasticity and Body Size under Competition in Waterfowl.

When differently sized species feed on the same resources, interference competition may occur, which may negatively affect their food intake rate. It is expected that competition between species also alters behaviour and feeding patch selection. To assess these changes in behaviour and patch selection, we applied an experimental approach using captive birds of three differently sized Anatidae species: wigeon (Anas penelope) (~600 g), swan goose (Anser cygnoides) (~2700 g) and bean goose (Anser fabalis) (~3200 g).

A Necrotizing Enterocolitis-Associated Gut Microbiota Is Present in the Meconium: Results of a Prospective Study.

Background: Anomalous intestinal microbiota development is supposedly associated with development of necrotizing enterocolitis (NEC). Our aim in this study was to identify the intestinal microbiota of patients at risk for NEC.

Methods: In a prospective trial that investigated prognostic factors for development of NEC in high-risk neonates (NTR4153), 11 NEC cases were gestational age/birthweight matched with controls (ratio of 1:2).

Optical coherence tomography accurately identifies patients with penile (pre) malignant lesions: A single center prospective study.

Introduction: Currently, (multiple) biopsies are taken to obtain histopathological diagnosis of suspicious lesions of the penile skin. Optical coherence tomography (OCT) provides noninvasive in vivo images from which epidermal layer thickness and attenuation coefficient (μoct) can be quantified. We hypothesize that qualitative (image assessment) and quantitative (epidermal layer thickness and attenuation coefficient, μoct) analysis of penile skin with OCT is possible and may differentiate benign penile tissue from (pre) malignant penile tissue.

Learning curve and interobserver variance in quantification of the optical coherence tomography attenuation coefficient.

The learning curve and interobserver variance of attenuation coefficient (μOCT ) determination from optical coherence tomography (OCT) images were quantified. The μOCT of normal and diseased vulvar tissues was determined at five time points by three novice students and three OCT experts who reached consensus for reference. Students received feedback between time points.

CO2 laser treatment for regional cutaneous malignant melanoma metastases.

Background: Cutaneous in-transit and satellite metastases are distressing presentations of melanoma progression.

Objective: The purpose of this study was to analyze the efficacy of carbon dioxide (CO2) lasers in patients with melanoma with cutaneous in-transit and satellite metastases.

Materials And Methods: Results of CO2 laser therapy were retrospectively evaluated in 22 patients between January 2004 and January 2008.

The value of optical coherence tomography in determining surgical margins in squamous cell carcinoma of the vulva: a single-center prospective study.

Background: Vulvar squamous cell carcinoma (VSCC) is treated with wide local excision. The challenge is to remove as much skin as necessary to prevent recurrence, but meanwhile preserve genital skin to diminish morbidity. Optical coherence tomography (OCT) is a noninvasive imaging tool that produces cross-sectional images.

Functional optical coherence tomography of pigmented lesions.

Background: Cutaneous melanomas are diagnosed worldwide in 231,130 patients per year. The sensitivity and specificity of melanoma diagnosis expresses the need for an additional diagnostic method. Optical coherence tomography (OCT) has shown that it allows morphological (qualitative) description of image features and quantitative analysis of pathology related light scattering by means of the attenuation coefficient (μoct ).
