Introduction: Intracranial empyema is a rare but serious and life-threatening infection. It is an accumulation of purulent material in the subdural or extradural space leading to development of subdural empyema or intracranial epidural abscess, respectively. The incidence of morbidity and mortality is high because the diagnosis is often unsuspected.

Article Synopsis
- * A rare case is presented where a wooden splinter became lodged in this area after a patient experienced an eyelid injury and an orbital floor fracture, with imaging not clearly showing the foreign body.
- * Rapid surgical exploration is crucial, as unidentified foreign bodies can lead to serious complications, and treatment should be customized based on individual circumstances.
Segmental Series and Size: Clade-Wide Investigation of Molar Proportions Reveals a Major Evolutionary Allometry in the Dentition of Placental Mammals.

Iterative segments such as teeth or limbs are a widespread characteristic of living organisms. While their proportions may be governed by similar developmental rules in vertebrates, there is no emerging pattern as regards their relation to size. Placental mammals span eight orders of magnitude in body size and show a wide spectrum of dietary habits associated with size and reflected in their dentitions, especially molars.

Investigating the molecular basis for tooth shape variation provides an important glimpse into the evolution of tooth function. We recently showed that loss of mesenchymal BMP7 is sufficient to alter morphology and function of the toothrow. Here we report on the underlying mechanism.

We describe the partial cranium and skeleton of a new diprotodontian marsupial from the late Oligocene (~26-25 Ma) Namba Formation of South Australia. This is one of the oldest Australian marsupial fossils known from an associated skeleton and it reveals previously unsuspected morphological diversity within Vombatiformes, the clade that includes wombats (Vombatidae), koalas (Phascolarctidae) and several extinct families. Several aspects of the skull and teeth of the new taxon, which we refer to a new family, are intermediate between members of the fossil family Wynyardiidae and wombats.
