An Interesting Case Of Acute Disseminated Encephalomyelitis
Acute disseminated encephalomyelitis (ADEM) is an uncommon inflammatory demyelinating disease of the central nervous system. The disease typically occurs after infections or vaccinations. However, in many patients with ADEM, no evidence of prior infection or vaccination can be found. We are reporting a patient who developed clinical and radiological features of acute disseminated encephalomyelitis after trauma of repeated attempts at lumber puncture for spinal anesthesi
Decomposition Strategies for Constructive Preference Elicitation
We tackle the problem of constructive preference elicitation, that is the
problem of learning user preferences over very large decision problems,
involving a combinatorial space of possible outcomes. In this setting, the
suggested configuration is synthesized on-the-fly by solving a constrained
optimization problem, while the preferences are learned itera tively by
interacting with the user. Previous work has shown that Coactive Learning is a
suitable method for learning user preferences in constructive scenarios. In
Coactive Learning the user provides feedback to the algorithm in the form of an
improvement to a suggested configuration. When the problem involves many
decision variables and constraints, this type of interaction poses a
significant cognitive burden on the user. We propose a decomposition technique
for large preference-based decision problems relying exclusively on inference
and feedback over partial configurations. This has the clear advantage of
drastically reducing the user cognitive load. Additionally, part-wise inference
can be (up to exponentially) less computationally demanding than inference over
full configurations. We discuss the theoretical implications of working with
parts and present promising empirical results on one synthetic and two
realistic constructive problems.Comment: Accepted at the Thirty-Second AAAI Conference on Artificial

Open vertical sagittal fracture patella with fracture lateral condyle femur: approach to a rare injury
Patellar fracture is a relatively uncommon fracture especially the vertical sagittal type.
In cases of high energy trauma injury, it is usually associated with fracture of ipsilateral
distal femur or proximal tibia. However, the combination of vertical sagittal fracture
patella and ipsilateral fracture lateral condyle is very rare. This necessitates judicious
diagnosis and appropriate management to ensure optimal functional outcome. Open
reduction and internal fixation is the treatment of choice in managing these types of
injuries. This should be followed by gradual mobilization of the affected knee joint.
Weight bearing can be started once the fracture starts showing signs of union on X-rays.
Literature search shows only one case report describing this pattern. The aim of this
case report is to highlight the rarity of this injury, to understand the injury mechanism
and surgical approach used for these injuries. The knowledge of this combination will
help us manage these injuries so that good functional outcome is achieved.
