Four domestic pet rabbits with dental pathology were presented at a university clinic. In addition to conducting physical examinations of the rabbits, radiographic and computed tomographic (CT) images of the rabbits' heads were obtained. Three rabbits were euthanized at the owners' request, and anatomic sections of the skulls were made. The observations of the anatomic sections, radiographs, and CT images are described. The abnormalities found on the radiographs and CT images were very similar to the findings on the anatomic sections. Compared to radiography, the CT images provided more details about the extent of the dental pathology, which is likely to be important for establishing a more precise prognosis and a more informed decision making process.

The anatomical innovation of sound-producing organs, which gives rise to a wide variety of sound signals, is one of the most fundamental factors leading to the explosive speciation of modern birds. Despite being a key clue to resolving the homology of sound-controlling muscles among birds, only few studies have explored the embryonic development of syringeal muscles. Using serial histological sections and immunohistochemistry, we described the three-dimensional anatomy and development of the cartilage, muscle, and innervation pattern of the tracheobronchi in three avian species: domestic fowls, cockatiels, and zebra finches.

Aneurysms of the interventricular membranous septum are a rare anatomical feature that can be detected incidentally on computed tomography or echocardiography. Such aneurysms can pose challenges in the treatment of patients with aortic valve stenosis. A case series of 2 patients with membranous septal aneurysms treated successfully with current-generation balloon-expandable and self-expanding transcatheter heart valves is presented here.

A 5-year-old male with xeroderma pigmentosum from Honduras presented with a rapidly growing mass on the left post-auricular neck, associated with left-sided hearing loss. MRI revealed a large mass with invasion of the external auditory canal, temporal bone, and metastasis to lymph nodes. Biopsy confirmed moderately differentiated squamous cell carcinoma (SCC).

Clinically, the rodent thorax is important because of the variety of problems that may affect the heart, lungs, and other thoracic structures. Syrian hamsters are the most common pet and experimental hamster species. Sectional imaging of small mammals is widely increasing in use for clinical and research settings; however, no reports on the thoracic sectional imaging anatomy in this species have been made.

The excessive buildup of neurotoxic α-synuclein plays a pivotal role in the pathogenesis of Parkinson's disease, highlighting the urgent need for innovative therapeutic strategies to promote α-synuclein clearance, particularly given the current lack of disease-modifying treatments. The glymphatic system, a recently identified perivascular fluid transport network, is crucial for clearing neurotoxic proteins. This review aims to synthesize current knowledge on the role of the glymphatic system in α-synuclein clearance and its implications for the pathology of Parkinson's disease while emphasizing potential therapeutic strategies and areas for future research.
