Application of deep learning algorithms in classification and localization of implant cutout for the postoperative hip.

Objective: This study aims to explore the feasibility of employing convolutional neural networks for detecting and localizing implant cutouts on anteroposterior pelvic radiographs.

Materials And Methods: The research involves the development of two Deep Learning models. Initially, a model was created for image-level classification of implant cutouts using 40191 pelvic radiographs obtained from a single institution.

Application of a deep learning algorithm in the detection of hip fractures.

This paper describes the development of a deep learning model for prediction of hip fractures on pelvic radiographs (X-rays). Developed using over 40,000 pelvic radiographs from a single institution, the model demonstrated high sensitivity and specificity when applied to a test set of emergency department radiographs. This study approximates the real-world application of a deep learning fracture detection model by including radiographs with sub-optimal image quality, other non-hip fractures, and metallic implants, which were excluded from prior published work.

Acute Hemiballismus as the Initial Manifestation of Ischemic Stroke: A Case Report.

Introduction: Cerebrovascular disease often presents with "negative" symptoms such as weakness with reduced movement of body parts or sensory loss. Rarely do "positive" symptoms such as abnormal movements manifest in acute stroke, with hemichorea being a very rare manifestation.

Case Report: This is a case report of a 62-year-old chronic smoker with no known past medical history who presented with choreatic movements of his arm and leg.

Factors associated with inappropriate attendances at the emergency department of a tertiary hospital in Singapore.

Introduction: Inappropriate attendances (IAs) at emergency departments (ED) are contributed by patients with mild or moderate medical conditions that can be effectively managed by primary care physicians. IAs strain limited ED resources and have an adverse impact on efficiency. This study aimed to identify factors associated with IA at the ED of a tertiary hospital in Singapore.

Spinal abscess: a case series.

Objective: Spinal abscess is a rare but potentially devastating condition. We present a case series, looking into its presentation, risk factors, management and outcome.

Methods: Five patients over a 10 year period were identified, with a discharge diagnosis code of 'spinal abscess, 324.

Utilization of a Glidescope videolaryngoscope for orotracheal intubations in different emergency airway management settings.

Objective: To describe the initial experience of a group of emergency department (ED) physicians, utilizing a Glidescope videolaryngoscope (GVL) for orotracheal intubations in the ED.

Methodology: A 6-month, single center, prospective observational study from 19 Feb 2007 to 18 Aug 2007 was conducted on all orotracheal intubations, which involved utilization of the original GVL in different emergency airway management scenarios.

Results: Overall success of GVL intubation was 15 out of 21 (71.

Monteggia 'fracture'-dislocation with bowing of the ulna: a pitfall for the unwary emergency physician.

We recently encountered a child who fell on the left outstretched hand. She complained of left elbow pain subsequently and radiographs showed a supposedly isolated radial head dislocation. This was spontaneously reduced when the left forearm was extended for another radiograph.

Disaster preparedness: Experience from a smoke inhalation mass casualty incident.

Objective: We describe a modified triage system used in managing a smoke inhalation mass casualty incident that we recently encountered at our community hospital.

Materials And Methods: The patients were triaged as priority 1, 2 or 3 on the basis of their symptoms, signs and circumstances at scene. In addition, the use of fibre-optic examinations of the upper airway, chest radiography and carboxyhaemoglobin levels with arterial blood gas analyses were used to aid in disposal plans.

Sigmoid volvulus: diagnostic twists and turns.

Objective: The purpose of this study was to describe the clinical profile of patients with sigmoid volvulus and highlight the diagnostic difficulties and pitfalls.

Methods: This was a retrospective descriptive study of patients with sigmoid volvulus seen at a community hospital over a 5-year period from July 1999 to July 2004.

Results: Twenty-eight cases of sigmoid volvulus were identified, of which 16 were male and 12 female.

Clinical predictors of bleeding esophageal varices in the ED.

Objectives: Some authors have found that thrombocytopenia (<118,000/mm3), splenomegaly, and ascites are useful predictors of large esophageal varices in cirrhotic patients. We decide to see whether these factors could also be used to predict bleeding esophageal varices in patients known to have chronic liver disease in the ED.

Methods: A case record review was done of all patients admitted to the ED of Changi General Hospital with upper gastrointestinal bleeding from esophageal varices from October 1999 to April 2004.

Radiologic screening for midfacial fractures: a single 30-degree occipitomental view is enough.

Background: The standard radiologic screening views for maxillofacial trauma in the accident and emergency department have been the Waters (30-degree occipitomental [OM]) view, the Caldwell (posteroanterior) view, and the lateral view. We wanted to see if a single 30-degree occipitomental view would be sufficient to screen for maxillofacial trauma (excluding nasal fractures).

Methods: Over a 1-year period, each of 730 patients had three radiologic views obtained for maxillofacial trauma at our emergency department.
