Parry Romberg syndrome(PRS) is a rare acquired poorly understood neurocutaneous syndrome of unknown etiology characterized by slow progressive atrophic changes commonly affecting one half of the face. The exact incidence and etiology towards the syndrome remains unclear. Apart from the multifactorial etiology proposed, the possible primary cause is mainly attributed to the cerebral disturbance of the fat metabolism. The syndrome overlaps with “en coup de sabre” morphea, with an ill defined relationship existing between the two. Parry Romberg Syndrome is an invalidating lesion that may be associated with different neurological, cutaneous, ocular, dental and autoimmune abnormalities. This report presents one rare case of 22 years old female patient with Parry Romberg syndrome associated with localized scleroderma, accompanied by a brief review of literature with classical clinical, radiographic, histological findings and the treatment of progressive hemifacial atrophy. Key words:Parry Romberg syndrome, progressive facial hemiatrophy, morphea, localized scleroderma.

We present a novel predictive statistical framework to improve the performance of an EigenTracker. In addition, we use fast and efficient eigenspace updates to learn new views of the object being tracked on the fly. We also incorporate a new Importance Sampling mechanism which increases the robustness of the EigenTracker, and enables it to track nonconvex objects better. Our EigenTracker is flexible -it is possible to use it symbiotically with other trackers. We show its successful application in hand gesture analysis; and face and person tracking.

Temporomandibular disorders embrace a number of clinical conditions that involves the masticatory musculature, temporomandibular joint (TMJ) and associated structures. The most frequent cause of TMJ disorders are disc derangement disorders which involve progressive slipping or displacement of articular disc. Various conservative treatment strategies for disc derangement disorders includes pharmacologic therapy, psychological counselling, treatment of parafunctional habits, use of occlusal splints and acupuncture which gives short term relief only. Recently, a non traumatic introduction to dentistry can be represented by low level laser therapy or soft laser therapy. It has proved to be an effective treatment modality in management of disc derangement disorders through its analgesic and anti-inflammatory effect. Therefore, the goal of this review article is to explore the use of low level laser therapy as an emerging trend in the management of disc derangement disorders of TMJ. KEY WORDS: low level laser, disc derangement disorders, orofacial pain.
