Normative Values for 18-30 Age Group of Benton Visual Retention Test Scores and Pre-morbid Intelligence Quotients: New Data Comparisons for Diagnosing Memory and Visual Spatial Deficits in Alzheimer's Disease and Stroke
The Benton Visual Retention Test (BVRT) is a well known test used to assess visual memory deficits and visual spatial abilities in patients. Normative data for the 18-30 age group is not presently covered thoroughly; hence, this study continues the work of previous series that examined data comprising BVRT scores, intelligence quotients (IQ), anxiety and depression levels, and gender effects. Correlations between pre-morbid estimates of IQ across different BVRT administrations were examined and discussed in order to compile a database of new data comparisons for this age group

Normative Values for 18-30 Ages of Benton Visual Retention Test Correct Scores and Intelligence Quotients: A Short Report for Clinical Comparison
The Benton Visual Retention Test (BVRT) is a well known test used to assess visual memory deficits and visual spatial abilities in patients. There is normative data available for the 18-30 age range though it is not comprehensive and does not cover the higher intelligence quotient ranges. Findings from two studies are presented in combination for use as normative correct score values

Scoping Review of the development of artificial eyes throughout the years
Losing an eye following trauma can lead to profound psychosocial difficulties making it imperative for the wearer to be fitted with an aesthetically pleasing custom-made artificial eye. Despite recent technological advancements, current design and manufacturing processes have remained unchanged in over 55 years. With the aim of portraying current knowledge regarding the development of artificial eyes in order to aid future development, a scooping review was conducted. Six online search engines were used: Scopus, PubMed, MedLine Complete, Web of Science, Science Direct and Google Scholar. Thirty-eight articles met the inclusion criteria and underwent numerical and thematic analysis with three thematic themes emerging. History and the current process of artificial eyes has been well documented, however, the impact of wearing artificial eyes is sparse. On-going research and development into the design and manufacturing processes of artificial eyes and the psychosocial impact of wearing an artificial eye is needed

Are Mock Jurors Influenced by the Defendants Gender, Socio-Economic Status and Emotional State in Forensic Medicine?
The aim of this study was to investigate whether mock jurors’ decisions were affected by the defendant’s gender, socio-economic status and emotional state in mock cases. The implications are far reaching, especially in trials that involve forensic medicine. An experimental design was used where a total of 24 participants from Bournemouth University took part, and were assigned to one of four groups. In these groups, the three independent variables were manipulated. Participants were presented with two murder/manslaughter cases. The results suggest male defendants received harsher judgements than female defendants. More female defendants were found not guilty than male defendants. Male defendants from a high socio-economic background received harsher judgements than male defendants from a low socio-economic background. Female defendants from a low socio-economic background received harsher judgements than female defendants from a high socio-economic background. Female defendants were found to be more trustworthy than male defendants. These findings are discussed are discussed in the context of the jury’s verdict, sentence length and personal opinion of the defendant

Retinoblastoma: Identifying the Diagnostic Signs for Early Treatment
Retinoblastoma is a rare but significant cause of childhood eye cancer world-wide. The prognosis depends upon early diagnosis and treatment but also upon accurate classification of the tumours. Unilateral incidence is normally non-hereditary compared with bilateral incidence where secondary tumours are more common. Survivorship is much better for unilateral compared with bilateral and trilateral retinoblastoma. Early signs are important to detect and photography can assist in identifying no return of “red-eye” during flash photography and yellow appearance of the tumour. Treatment options are discussed together with new psycho-oncology approaches that address potential trauma in the survivor as well as in the family of the survivor

The importance of incorporating technological advancements into the artificial eye process: a perspective commentary
Application of technology into healthcare has typically been targeted to high demand illnesses and treatments. However, with an increasing need to meet patient’s expectations combined with increased accessibility and reduced costs, smaller healthcare fields are starting to investigate its function and usability. Services have historically been led by skills and expertise, and recent developments are being seen by ocularists in the field of prosthetic eyes who acknowledge the potential benefit from technological advancement. Utilising the technologies recently investigated in maxillofacial prosthesis can start the evolutionary process where products are continually re-designed and re-developed to achieve excellent patient outcome and satisfaction levels

Establishing normative values for 18-35 years age in neuropsychological tests used with head and brain injury patients during cognitive rehabilitation: Benton Visual Retention Test and National Adult Reading Test
The Benton Visual Retention Test (BVRT) is a neuropsychological assessment of visuo-spatial and visuo-memory ability. Claims of high reliability and validity are based on solitary samples representative of a wide age range. This study validated theBVRTagainst the National Adult Reading Test (NART), a highly validated and reliable test of estimated pre-morbid IQ in an age-specific group of participants (18-35 years).
Using Between-subjects factorial design, fifty-three participants (24 female, 29 male) aged 18-35 years (inclusive) were administered the NART and 3 administrations of the BVRT.
Significant positive correlations were found betweenBVRTError scores and NART Error scores for administrations B and C of theBVRTwhich is when presented stimuli are followed by a short time delay before allowing respondents to recall. Significant negative correlations were found over these administrations forBVRTCorrect scores and NART Error scores. No significant relationship was found between depression and performance on theBVRT. However, a weak, non-significant relationship was found between anxiety andBVRTperformance.
The BVRTis a well-validated and highly reliable neuropsychological test of visuo-spatial and visuo-memory abilities. Findings provide new data for the 18-35 years age group as well as providing a cautionary note on the possible influence of anxiety on performance levels in light of the frequent occurrence of anxiety post-neurological injury
Gravity changes from a stress evolution earthquake simulation of California
The gravity signal contains information regarding changes in density at all depths and
can be used as a proxy for the strain accumulation in fault networks. A stress evolution
time-dependent model was used to create simulated slip histories over the San Andreas
Fault network in California. Using a linear sum of the gravity signals from each fault
segment in the model, via coseismic gravity Green's functions, a time-dependent gravity
model was created. The steady state gravity from the long-term plate motion generates
a signal over 5 years with magnitudes of ±~2 μGal; the current limit of portable
instrument observations. Moderate to large events generate signal magnitudes in the
range of ~10 to ~80 ÎĽGal, well within the range of ground-based observations. The
complex fault network geometry of California significantly affects the spatial extent of the
gravity signal from the three events studied.Peer reviewe
Rapunzel syndrome: A South African variety
Trichobezoars are intraluminal accretions of ingested hair. Rapunzel syndrome is a rare and extreme presentation, with the trichobezoar extending into the small intestine. It is most frequently reported in children and psychiatric patients. We report a South African series of 5 patients who presented with trichobezoars. Each patient was retrospectively reviewed and analysed with regard to background, demographics, clinical presentation, diagnosis, surgical management and complications. Five female patients with a median age of 19 (range 12 - 27) years presented with clinical symptoms, including early satiety, intermittent vomiting with gastric outlet obstruction, abdominal pain and weight loss. The diagnosis was made by endoscopy, abdominal computed tomography (CT) imaging, barium meal examination or plain abdominal radiography. Two patients presented with sealed/contained gastric perforations, and 1 patient with a small-bowel perforation. All 5 bezoars, 2 of which consisted entirely of artificial hair extensions, extended into the jejunum, the longest measuring 1.4 m. All were removed by laparotomy. While trichobezoars are a rare entity, they may present with significant complications, such as obstructions and perforations. In view of the infection risk and considerable size of many of these bezoars, an open removal is probably safer than any minimally invasive attempt
