The face provides an important channel for communicating affect valence, the positive or negative emotional charge of an experience. This paper addresses the challenging pattern recognition problem of assigning affect valence labels (positive, negative or neutral) to facial action sequences obtained from unsegmented videos coded using the Facial Action(More)

As predicted by the dual systems theory of want/should conflict, uncertainty about what the future may bring increases(More)

Clinical forms of leishmaniasis are particularly diverse representing a complex of diseases. We present a case of lingual Leishmaniasis in an immunocompetent man. The lesions were caused by Leishmania donovani/infantum(More)
The common sites for metastasis of renal cell carcinoma are lung, kidney, adrenal glands, liver, and contralateral kidney. We report an unusual case of cutaneous metastasis of renal cell carcinoma in a 68-year-old woman who was treated for renal cell carcinoma with partial right nephrectomy and multikinase angiogenesis inhibitor (sunitinib) 10 years ago.
Ohnishi in 1975 first described temporomandibular joint (TMJ) arthroscopy. Along with its extensive use, a range of complications has emerged. We describe a patient who experienced parapharyngeal swelling after undergoing arthroscopy. Prolonged intubation up to 1 hour postoperatively was required. The swelling resolved completely over 6 h without further(More)
KEY CLINICAL MESSAGE The routine way to access the uncomplicated airway is via direct laryngoscopy. When this is not possible, there are a number of other techniques to help visualization such as the video laryngoscopy. These require a degree of mouth opening. With almost complete trismus, the clinician should resort to awake fibreoptic nasal intubation to(More)
KEY CLINICAL MESSAGE Not all orbital fractures are associated with clinical signs of swelling, ecchymosis, and subconjunctival hemorrhage. The "white-eyed" blowout fracture is more commonly seen in children and is associated with entrapment of the extraocular muscles. Early surgical intervention is indicated and it must have been in the differential(More)
