X-ray interpretation is a fundamental skill in emergency practice. Post-operative eyes with implants may sometimes pose clinical challenges on post-traumatic event diagnosis and differentiation from organ wasting. Recommended by authorities and guidelines, computed tomography is indicated for evaluation of head injury cases, yet incidental abnormal findings such as radiopacity in the eyeball might create dilemma to diagnosis. History taking and clinical examinations are essential for the interpretation of the radiopacity in orbital imaging. Subtle and uncommon radiological findings of the eye will be discussed.

Abstract Background: Calcitonin gene-related peptide (CGRP) has only recently emerged as a potential target in posttraumatic headache. To our knowledge this is the first description of a patient with persistent posttraumatic headache following severe traumatic head injury who has been treated with the CGRP-receptor-monoclonal antibody erenumab.Case presentation: A 56-year-old man presented with a 30-year history of frequent migraine-like posttraumatic headaches following a high-voltage head injury that he treated with an excessive intake of peripheral analgesics. Although amitriptyline was reasonably effective, it had to be discontinued when the patient developed restless legs syndrome in the second year of treatment. Under therapy with erenumab he achieved a rapid and stable reduction in his symptoms down to only 2–3 headache days per month without adverse events.Conclusions: This case demonstrates that the inhibition of the CGRP-receptor with erenumab could be an effective treatment option in migraine-like post-traumatic headache even decades after the traumatic event.

Ehlers and Clark (2000) recently published a rigorous cognitive behavioural model of PTSD. Part of the model explains how the phenomenon of “affect without recollection” can emerge in PTSD. This happens when the re-experiencing phenomena occur without explicit or conscious recall of the parts of the traumatic event from whence the phenomena originated. The following paper presents a case study of a man with PTSD and head injury in which there was complete organic amnesia for the trauma but where re-experiencing of the event occurred via implicit conditioned responses to reminders of the event. It provides elegant supportive evidence for the phenomenon of “affect without recollection” where both PTSD and severe head injury are present.

The use of x-ray and computed tomography scan is critical in the management of traumatic conditions, particularly head injuries. This study was carried out to assess the level of awareness and attitude of Emergency physicians towards the use of CT in cases of head injury. A cross-sectional study was done among emergency physicians working in five different government hospitals in Anambra State. Among the respondents were 29% males and 4% females: mean age was 35.7 years while their modal age was 31-40 years. All the respondents, 33 (100%) stated they find CT scan as a useful diagnostic medical imaging modality. However less than half of them, 15 (45.5%) stated they refer patients for CT scan for those patients that need it. Whereas most of them, 20 (64.5%) stated that head injury patients should undergo both X-Ray and CT scan virtually all of them 32 (97%), responded that computed tomography, (CT) is better than skull x-ray in the examination of head injury. Though majority of the respondents 31 (93%), stated that CT scan subject the patient to some risks. All those who responded and thought that CT scan should continue to be used as medical diagnostic imaging modality were 33 (100%). The result of the study showed that most of the emergency physicians are aware of the usefulness of CT in the examination of patients presenting with head injury, but the non- availability and cost of services of the CT imaging equipment greatly affected the rate of request for the examination and has affected their attitude towards the use of this imaging modality in the examination of this category of patients in need of it.

Background: Pulmonary Tuberculosis (PTB) is a major public health problem in Nepal. Diag­nosis of pulmonary tuberculosis is done by bacteriological confirmation of respiratory speci­men however Negative smear needs clinical and radiological evaluation for the diagnosis in suspected patient. This study focuses on radiological findings in both Pulmonary bacterio­logically confirmed (PBC) and pulmonary clinically diagnosed (PCD) Tuberculosis. Methods: This observational study was conducted at Chitwan Medical College between Feb 2019 to July 2019. 45 Patient diagnosed with PTB were enrolled. Chest X-ray (CXR) and High Resolution Computed Tomography (HRCT) chest reports were analysed for the presence of findings that suggest active infection like cavity, consolidation, tree in bud, etc in PBC and PCD. Results: A total of 45 PTB patients with mean age: 54.60 ± 19 years were included. 53.3 % were PBC and 46.7 % were PCD tuberculosis, CXR findings in PBC and PCD tuberculosis was nodular infiltrate 45.8% versus 2.4%, consolidation 45% versus 42.9%, cavity 8.3% versus 14.3% respectively however 12.5% PBC tuberculosis patient had a normal chest x-ray. HRCT chest in PBC and PCD showed cavity in 45.8% versus 23%, tree in bud 25% versus 52.4%, con­solidation 62.5 versus 57.1%, ground glass opacity 29.2% versus 23.8% respectively and none of the HRCT chest was normal. In comparison to the CXR, HRCT chest shows more cavitary lesions in PBC and tree in bud was more common in PCD. Conclusions: This study has found that radiological findings suggestive of active PTB was more obvious in HRCT than CXR. Presence of cavity, lobar consolidation and tree in bud lesion in HRCT chest were more frequently observed in both PBC and PCD Tuberculosis.

Three Dimensional Images

We have developed a new X-ray microscope which produces complete three dimensional images of samples. The microscope operates by performing X-ray tomography with unprecedented resolution. Tomography is a non-invasive imaging technique that creates maps of the internal structure of samples from measurement of the attenuation of penetrating radiation. As conventionally practiced in medical Computed Tomography (CT), radiologists produce maps of bone and tissue structure in several planar sections that reveal features with 1mm resolution and 1% contrast. Microtomography extends the capability of CT in several ways. First, the resolution which approaches one micron, is one thousand times higher than that of the medical CT. Second, our approach acquires and analyses the data in a panoramic imaging format that directly produces three-dimensional maps in a series of contiguous stacked planes. Typical maps available today consist of three hundred planar sections each containing 512x512 pixels. Finally, and perhaps of most import scientifically, microtomography using a synchrotron X-ray source, allows us to generate maps of individual element.

Abstract—The type material on which the fossil genus name Ampelocissites was established in 1929 has been reexamined with the aid of X-ray micro-computed tomography (μ-CT) scanning and compared with seeds of extant taxa to assess the relationships of these fossils within the grape family, Vitaceae. The specimens were collected from a sandstone of late Paleocene or early Eocene age. Although originally inferred by Berry to be intermediate in morphology between Ampelocissus and Vitis, the newly revealed details of seed morphology indicate that these seeds represent instead the Ampelopsis clade. Digital cross sections show that the seed coat maintains its thickness over the external surfaces, but diminishes quickly in the ventral infolds. This feature, along with the elliptical chalaza and lack of an apical groove, indicate that Ampelocissites lytlensis Berry probably represents Ampelopsis or Nekemias (rather than Ampelocissus or Vitis) and that the generic name Ampelocissites may be useful for fossil seeds with morphology consistent with the Ampelopsis clade that lack sufficient characters to specify placement within one of these extant genera.
