From the time of conception, stress is present in human life (1).Stress either physical or psychological can induces neural, endocrine and behavioural responses and depends on personal relevance.generalized nociceptive hypersensitivity and alterations in pain sensitivity in stress is determined by pressure pain threshold ( PPT) measured by the algometer.aim and object of the study is to evaluate the relation of stress and painin healthy young medical girls students by observing the changes in the PPT (pressure pain threshold) of different groups of muscle of upper limb during the examination stress.. Materials and Methods :Sudy was conducted on 30 healthy young girls medical students of 1st year in the department of physiology ,Ruhscmsjaipur..subject group were examined 15 day before the examination and one day before the examination.PPT of the dominant upperb limb muscles egTricep, Biceps and dorsam of hand. RESULT: pressure pain threshold (PPT) of the biceps and hand muscles have a significantly positive correlation with the acute stress of examination than the triceps muscles which have a non significant correlation P value of biceps and hand muscles and triceps muscle is(003) and(.000)and (112).respectively.,Discussion :Increased pain sensititivity in the examinedmuscles isdue to disinhibiting central nervous system structures involved in regulation of attention eg:-ascending reticular activating system, HPAaxis,brain neuronal activity resulting in sensitization of nociceptive neurons and in enhanced pain sensitivity .conclusion: acute stress of examination modulates pain in humans and contributes to individual variability in pain affect and painrelated brain activity.

Maxillofacial injuries sustained through Road traffic accidents (RTAs) is one of the leading causes of hospitalization in India. Numerous factors such as ever increasing amount of two wheelers, assault conditions, lack of safety measures such as helmets, seat belts and lack of strict implementation of such rules, prevailing socioeconomic, cultural and environmental factors results in a substantial number of facial fractures from RTAs. By 2020, RTA injuries will rise as the 6th major cause of death worldwide. One of the most commonly employed means to thwart such RTAs include the use of helmet, following speed limits, obeying stop signs and traffic signals. Among two wheelers, the use of Helmets plays a crucial role in protecting the cranial vault and potentially the facial skeleton if a full face helmet is used. 25% of the RTAs are caused due to two wheelers rather than four wheelers. Pillion rider, who ride passenger behind the rider on a two wheelers more suspectible to morbid injuries due to lack of safety measures like not wearing a helmet, improper sitting patterns especially by females in India. A study showed injuries such as contusion and skull fractures are common when riding pillion. Here we report a case of mandibular symphysis fracture along with bilateral subcondylar fracture with medial displacement of the fractured segment sustained via RTA while riding pillion.
