Object Models

Ingested or penetrating foreign bodies are common in veterinary medicine. When they are radiolucent, these objects become a diagnostic challenge, but they can be investigated sonographically. However, successful object identification depends on the skill of the sonographer. Considering that these cases appear randomly during hospital routines, it is not always possible to train all students to identify them correctly. Therefore, the aim of this study was to produce homemade simulations of radiolucent foreign bodies for veterinary student demonstrations that could be identified sonographically and to evaluate the acceptability, applicability, and usefulness of these simulations according to a visual analog scale questionnaire and subjective questions. For this purpose, object models (a pacifier nipple, a toy ball, a sock, nylon thread, and a mango seed) were designed, produced, and immersed in gelatin. To simulate wood splinters in the integumentary and musculoskeletal system, a piece of meat punctured with a toothpick and ice cream stick splinters were used. The type of phantom had a determinant effect on the visualization (chi-square = 36.528, P < 0.0001) and recognition (chi-square = 18.756, P = 0.0021) capability of the students. All of the students answered that their experience with the models could help in real situations. The student responses to the questionnaire indicated that the project was well accepted, and the participants believed that this experience could be applicable to and useful in veterinary routines.

Modern Contraceptive Use

Despite the benefit of modern contraception, its use remains low in Nigeria. This study examined belief system as a barrier to the use of modern contraceptives among the Idoma of Benue State, North Central Nigeria. Questionnaire ( n = 1107), in-depth interview ( n = 6) and focus group discussion ( n = 52) were used to collect data from three local government areas (LGAs). The results showed high levels of knowledge (88.0%), however, only 37.8% used modern contraceptives. The male condom had the highest percentage use (56.7%). Chi-square results showed that LGA, education and occupation were significantly related to the use of modern contraceptives. Being of greater age increased the likelihood of use, whereas higher levels of education and income decreased the likelihood of modern contraceptive use ( p < 0.05). Qualitative data indicated that married women were expected to eschew modern contraceptives due to their belief in Alekwu, the community deity. Designing interventions that are culturally specific could promote use of modern contraceptives among the group.

Review Current

Foreign bodies can present a diagnostic challenge to even the experienced surgeon. In one review of 200 surgical cases involving retained foreign bodies, one-third of the cases had been initially missed.1 Wooden foreign bodies in particular pose a challenge to the physician. In the review cited above, only 15% of wooden foreign bodies were well visualized on plain radiographs.1 Acutely, on computed tomography (CT) scans, wooden foreign bodies will usually mimic air.2 However, with time, the attenuation value of a wooden foreign body may increase as moisture is absorbed from the surrounding tissues.3 Once this occurs, the wooden foreign body may mimic fat, water or muscle.2 We present an interesting case of a wooden foreign body in the parotid gland in order to illustrate a common presentation of such a foreign body, to review current guidelines for their clinical and radiologic diagnosis, and to suggest strategies for the management of their unique complications.

Background. Dentures are a common cause of inadvertent foreign body ingestion particularly in the elderly. Due to their radiolucent nature, they often present a diagnostic challenge to care providing physicians. Case Presentation. A 66-year-old female presented to our otolaryngology clinic with a 2-year history of dysphagia. Her physical examination was unremarkable. Computed tomography scan of the neck and barium swallow suggested Zenker diverticulum. She was planned for endoscopic diverticulotomy; however, during surgery, a foreign body was incidentally found and retrieved, which was a partial lower denture. The diverticulum resolved thereafter, and the patient's symptoms abated. Conclusion. The authors recommend evaluating the esophagus endoscopically first in cases of upper esophageal diverticular formation, even when planning an open repair approach, to rule out any concealed foreign bodies.

Unilateral Proptosis

Objective: To study epidemiology, presentation and management of cases with unilateral proptosis presenting at a tertiary care hospital. Study Design: Case series. Place and Duration of Study: Armed Forces Institute of Ophthalmology, Rawalpindi Pakistan, from Jan 2016 to Dec 2017. Methodology: Retrospective analysis of hospital record of patients with unilateral proptosis was carried out. Data was entered and analyzed in SPSS version 22. Chi square test was used for statistical analysis. Results: Thirty-three cases of unilateral proptosis with a mean age of 41.79 ± 3.87 years were included in the study. Pain was the most common association. Proptosis was mild in 42.4%, moderate in 48.5% and severe in 9.1% cases. In 61% cases, diagnosis was made on excisional or incisional biopsy and on the basis of radio imaging in 39% cases. Most common cause of proptosis found was pleomorphic adenoma (12%). Patients with axial and non-axial proptosis were 48.5% and 51.5% respectively. Fourteen cases (42.5%) were managed surgically and 2 cases (6%) were observed. Total of 22 cases (67%) improved after treatment, 8 cases (24%) went into remission, 2 (6%) deteriorated, and 1 (3%) died in the study period. Conclusion: Unilateral proptosis is a diagnostic challenge. Pertinent history taking and detail examination is the key, but associated signs or symptoms not always point towards correct diagnosis. Tissue biopsy provides a conclusive diagnosis especially where radio imaging is doubtful.

The coronavirus pandemic abruptly halted all in-person clerkships, or clinical rotations, for clinical veterinary students across the United States (US). Online clerkships in radiology offered the opportunity to expand the student’s ability to interpret medical images but did not allow for the development of physical hands-on imaging skills recognized as core competencies in veterinary medicine. The present report highlights the value of providing veterinary students with a smartphone-associated Butterfly iQ point-of-care ultrasound during a 3-week self-driven virtual clerkship. During the virtual rotation, the student was able to develop the skills required to generate sufficient quality images using three horses residing on her property. The affordability, portability, ease of use of the Butterfly iQ and availability of animals made it possible to develop hands-on imaging skills when distance learning was required.

This chapter is in the scope of static and dynamic discovery-driven explorations of a data cube. It presents different methods to facilitate the whole process of data exploration. Each kind of analysis (static or dynamic) is developed for either a count measure or a quantitative measure. Both are based on the calculation, on the fly, of specific statistical built-in indicators. Firstly, a global methodology is proposed to help a dynamic discovery-driven exploration. It aims at identifying the most relevant dimensions to expand. A built-in rank on dimensions is restituted interactively, at each step of the process. Secondly, to help a static discovery-driven exploration, generalized statistical criteria are detailed to detect and highlight interesting cells within a cube slice. The cell’s degree of interest is determined by the calculation of either test-value or Chi-Square contribution. Their display is done by a color-coding system. A proof of concept implementation on the ORACLE 10g system is described at the end of the chapter.

Radiographic Presentation

This paper describes a case of an intra-osseous foreign body impaction in the hard palate, a chicken bone fragment, in an adult male. The presentation mimicked that of an odontogenic lesion. Though palatal soft tissue foreign bodies in toddlers are well reported, the literature is sparse on cases involving adults. The location of the foreign body, and radiographic presentation, resulted in a diagnostic challenge to the attending clinician. This appears to be the first reported case of an animal bone presenting in this way in an adult. CPD/Clinical Relevance: The case highlights the importance of credible history reporting, 3D imaging and developing accurate differentials in the diagnostic pathway when faced with an atypical clinical presentation.
