Cases of cranial superficial epigastric vein (CSEV) phlebitis with subsequent septicemia were observed in dairy farms in Minas Gerais, Brazil. Autopsy on 4 affected cows, from 2 farms, revealed CSEV thrombophlebitis with perivascular abscesses, pulmonary abscesses, valvular endocarditis, arthritis, thromboembolic nephritis, and renal infarcts. Microscopic examination revealed fibrosing and lymphoplasmacytic phlebitis with occasional endothelial loss, subendothelial areas of necrosis, and abundant fibrin deposition. , and were isolated from lesions of 3 different cows. Thrombophlebitis of the CSEV is a rare condition in dairy cows; however, it has become more frequent in dairy farms in southeastern Brazil after repeated venipuncture of this vein, likely with contaminated needles used for administration of oxytocin.

Surgical Approaches to Pre-Auricular Cutaneous Squamous Cell Carcinomas Extending to the Temporal Bone.

Department of Otolaryngology, Head and Neck Surgery, Princess Alexandra Hospital, Queensland Skull Base Unit, Brisbane, Queensland, Australia.
Background: Standardized surgical approaches to advanced pre-auricular cutaneous squamous cell carcinomas (cSCC) are lacking.
Methods: Fifty-four patients who underwent lateral temporal bone resection (LTBR) for pre-auricular cSCC were grouped into "Levels" of increasing disease spread. Surgical approaches to achieve negative-margin resection were designed for each Level and replicated on cadaveric specimens.
Topographic Analysis of the Periorbital Region Including Orbicularis Oculi Muscle Based on Ultrasonography Interpretation.

Objective: Ultrasonographic examination is easy, fast, safe, and used in various fields; however, its application to the facial area has been limited. Complex anatomical structures are mixed within thin, soft tissues in the facial region; therefore, understanding their structural characteristics is crucial. This study aimed to use ultrasonography to obtain information on the layered structure and soft tissue thickness of the eye area around the orbicularis oculi muscle and provide guidance for clinical practice.

Objective: Transcranial electrical stimulation (TES) is an effective technique to modulate brain activity and treat diseases. However, TES is primarily used to stimulate superficial brain regions and is unable to reach deeper targets. The spread of injected currents in the head is affected by volume conduction and the additional spreading of currents as they move through head layers with different conductivities, as is discussed in [1].

Background: Approximately 25% of children in the United States experience child abuse or neglect, 18% of whom are physically abused. Physicians are often in a position to differentiate accidental trauma from physical child abuse. Therefore, the aim of this study was to review recent literature for risk factors associated with physical child abuse.

As lineages become separated in time, they are expected to accumulate mutational (or developmental-genetic) differences that influence the macroevolutionary trajectories of those lineages even under similar environmental conditions. Here, we compare the dynamics of phenotypic evolution in radiations of scincid lizards from Australia and Madagascar that are separated by more than 100 million years of independent evolution and show rampant phenotypic parallelism. We collected linear measurements of the skull, limbs, and limb girdles from micro-CT scans of 94 Australian and 29 Malagasy species.
