Abstract. The aim of the work is to develop forensic criteria for differential diagnosis traumatic hemorrhages (HTG), ischemic stroke (IS), and nontraumatic genesis (HNG) formation by 3D Mueller-matrix microscopy layers azimuthal-invariant images circular birefringence histological sections brain. Material methods. Native brain taken from 110 corpses were used study in case of: death coronary h...

Paraplegia is a well-defined state of complete motor deficit in lower limbs, regardless of sensory involvement. The cause of paraplegia usually guides treatment, however, some controversies remain about the time and benefits for spinal cord decompression in nontraumatic paraplegic patients, especially after 48 hours of the onset of paraplegia. The objective of this study was to evaluate the ben...

The authors report a case of nontraumatic, spontaneous dislocation of a polyethylene insert detected 1 year after total knee arthroplasty. The patient demonstrated initial improvement and returned to work 4 months postoperatively. At 6 months postoperatively, the patient developed pain and a clunking sensation with motion; however, he denied any traumatic precipitating events. An arthroscopic p...

We conducted a prospective study that tracked the frequency of potentially traumatic events (PTEs) and nontraumatic events among college students over a 4-year period using a weekly web-based survey. At the study’s completion, participants attempted to recall the number of events they had endorsed on the web surveys. Although participants underrecalled the frequency of all types of life events,...

Objective: To report a rare non traumatic fracture of femur after a partial secondarily generalized tonic seizure in a infant. Description – A 7-month-old female patient was referred to the Pediatric Hospital with two complaints: 1) frequent epileptic seizures since the age of 3 months and 2) intermittent crying when the left leg is moved or manipulated after last seizures. Computerized tomogra...

A case is reported of a Japanese female in whom acute right subdural hematoma due to the spontaneous rupture of the posterior branch of the right central artery occurred shortly after the onset of hypertensive subcortical hemorrhage of the right occipital lobe. Marked hypertension persisted. There was no evidence of subdural hematoma when a small collection of extravasated contrast medium from ...

High-field MR imaging was used to study structural and physiologic alterations involving the muscles of mastication in 46 patients. Muscular abnormalities were often detected incidentally in conjunction with lesions of the CNS, cranial nerves, facial bones, and/or temporomandibular joint (TMJ). Specific pathologic alterations observed included anomalies of musculoskeletal development, muscle hy...

Atraumatic splenic rupture (ASR) is an uncommon pathologic condition in which bleeding from the spleen occurs for a variety of nontraumatic reasons. While the current trend in traumatic splenic rupture is nonoperative management including transcatheter arterial embolization, the current recommendation for the treatment of most patients with ASR is splenectomy. In this report, we describe two ca...

Since posttraumatic stress disorder (PTSD) was first recognized as a psychiatric disorder, it has generated a great deal of scientific interest. Recent studies on the neurobiology of PTSD provide evidence that PTSD is biologically distinct from other types of traumatic and nontraumatic stress responses. This paper reviews three important directions of neurobiological research in PTSD: noradrene...

Acromioclavicular dislocation (AC dislocation) is a common injury of the shoulder. In contrast to a traumatic cause, nontraumatic dislocation is very rare. We report on a 17-year-old female that presented with voluntary recurrent dislocation of the right AC joint followed by recurrent pain without instability of the ipsilateral shoulder. Clinical examination showed crepitation as well as palpit...
