AI Article Synopsis

  • Acquired dental issues are common in pet rabbits, but early symptoms are often missed as rabbits can appear symptom-free at first.
  • Changes in anatomical reference lines in skull X-rays can indicate dental health issues, yet there are exceptions where these lines may not be applicable.
  • A study on 80 pet rabbits found that skull shape varies notably, with the palatal angle being a key factor; rabbits with a palatal angle greater than 18.8° may not be suitable for using the anatomical reference lines for diagnosing dental diseases.

Article Abstract

Acquired dental problems are among the most frequently encountered diseases in pet rabbits. However, early symptoms are often overlooked because the affected animals first appear completely asymptomatic. Alterations from anatomical reference lines according to Böhmer and Crossley applied to standard skull X-ray images, have been shown to be indicative of tooth health problems in pet rabbits. Despite its proven usefulness, there are exceptions in which the anatomical reference lines appear not to be suitable for application. We addressed this issue by quantifying the cranial morphology of a large data set of pet rabbit patients (N = 80). The results of the morphometric analyses revealed considerable diversity in skull shape among the typical pet rabbits, but variance in only a few parameters influences the applicability of the anatomical reference lines. The most substantial parameter is the palatal angle. Specimens in which the anatomical reference lines could not be applied, have a rather large angle between the skull base and the palatal bone. We recommend to measure the palatal angle before applying the anatomical reference lines for objective interpretation of dental disease. Pet rabbits with a palatal angle larger than 18.8° are not strictly suitable for the successful application of the anatomical reference lines.

Aim: This study investigated the accuracy of intraoral scanner (IOS) based on different image acquisition technologies in the field of presurgical-orthopedictreatment (PSOT) in neonates with cleft.

Methods: Dental cast models of clinical situations representing unilateral cleft-lip-palate(UCLP), bilateral cleft-lippalate( BCLP) and cleft-palate(CP) with reference PEEK-scanbodies (Cares RC Mono-Scankörper, Straumann, Switzerland) were scanned utilizing four IOS systems: CareStream-CS3600®(CS), Medit-i500®(MD), Cerec-Omnicam®(SO), 3Shape-Trios-3®(TS). One calibrated operator made 5 scans from each model using each IOS (N=60).

There has been an increased interest in standardized approaches to coding facial movement in mammals. Such approaches include Facial Action Coding Systems (FACS), where individuals are trained to identify discrete facial muscle movements that combine to create a facial configuration. Some studies have utilized FACS to analyze facial signaling, recording the quantity of morphologically distinct facial signals a species can generate.

Variations of the ankle anatomy are infrequent and exist as supernumerary muscles and tendons. Often understudied and overlooked, their presence can cause many complications of the lower extremity. These muscles, although often asymptomatic, can cause great pain and complications such as tenosynovitis, tarsal tunnel syndrome, lateral ankle instability, and ankle pain when they impinge on the normal anatomy of the patient.

Ventricular Depolarization Abnormalities and Their Role in Cardiac Risk Stratification - A Narrative Review.

Rev Cardiovasc Med

Department of Cardiovasculair Sciences, KU Leuven, 3000 Leuven, Belgium.

Ventricular depolarization refers to the electrical activation and subsequent contraction of the ventricles, visible as the QRS complex on a 12-lead electrocardiogram (ECG). A well-organized and efficient depolarization is critical for cardiac function. Abnormalities in ventricular depolarization may indicate various pathologies and can be present in all leads if the condition is general, or in a subgroup of anatomically contiguous leads if the condition is limited to the corresponding anatomic location of the heart.

Successful Mechanical Thrombectomy for Bilateral Anterior Cerebral Artery Occlusions in a Rare Anatomical Variant: A Case Report.

Int Med Case Rep J

Department of Cardiology, Rugao Affiliated Hospital of Nantong University, Rugao People's Hospital, Nantong, Jiangsu, People's Republic of China.

Background: Acute ischemic stroke (AIS) is usually caused by acute occlusion of the cerebral artery. Bilateral anterior cerebral arteries (ACAs) originating from the anterior communicating branch of the same internal carotid artery are a rare anatomical variation in clinical practice. Mechanical thrombectomy (MT) of simultaneous acute occlusion of the bilateral ACAs with this variation has rarely been reported.
