Whiplash Trauma

Whiplash trauma can result in injuries that are difficult to diagnose. Diagnosis is particularly difficult in injuries to the upper segments of the cervical spine (craniocervical joint [CCJ] complex). Studies indicate that injuries in that region may be responsible for the cervicoencephalic syndrome, as evidenced by headache, balance problems, vertigo, dizziness, eye problems, tinnitus, poor concentration, sensitivity to light and pronounced fatigue. Consequently, diagnosis of lesions in the CCJ region is important. Functional magnetic resonance imaging is a radiological technique that can visualize injuries of the ligaments and the joint capsules, and accompanying pathological movement patterns.Three severely injured patients that had been extensively examined without any findings of structural lesions were diagnosed by functional magnetic resonance imaging to have injuries in the CCJ region.These injuries were confirmed at surgery, and after surgical stabilization the medical condition was highly improved.It is important to draw attention to the urgent need to diagnose lesions and dysfunction in the CCJ complex and also improve diagnostic methods.

Silver nanoparticles with 5–10 nm diameters are synthesised using Couroupita guianensis flower extract. The synthesised silver nanoparticles found to show good antimicrobial activity against gram negative and gram positive bacteria. Poly(methyl methacrylate) nanofibers with pristine, surface roughened and coaxial hollow forms are prepared by electrospinning. The structural and morphological properties of these pure and structurally modified poly(methyl methacrylate) nanofibers are evidenced by various analytical techniques. The antimicrobial studies of poly(methyl methacrylate) nanofibers having different architectures incorporated with silver nanoparticles are carried out. It is found that, all the three forms of poly(methyl methacrylate) nanofibers incorporated with silver nanoparticles show antibacterial properties against both gram positive and gram negative bacteria. Among these, surface roughened poly(methyl methacrylate) nanofibers incorporated with silver nanoparticles show highest antibacterial activity than the other two structural forms. The present study offers an alternative to the existing optical lenses. People especially those who suffer from eye problems can protect their eyes in a better way from infectious agents by wearing optical lens made from C. guianensis stabilised silver nanoparticles incorporated poly(methyl methacrylate) nanofibers than that made from pure poly(methyl methacrylate) nanofibers or films.

Eye Examination

Vision screening and eye examination are important for the detection of conditions that distort or suppress the normal visual image and, ultimately, may lead to blindness in children. Examination of the eyes can and should be performed at any age, beginning in the newborn period. Vision screening should be performed at as early an age as is practicable. Conditions that interfere with vision are of grave import because visual stimuli are critical to the development of normal vision. Decreased visual acuity often contributes to inadequate school performance. In addition, retinal abnormalities, cataract, glaucoma, retinoblastoma, eye muscle imbalance, and systemic disease with ocular manifestations may all be identified by careful examination. Vision screening should be carried out as part of a regular plan of continuing care, beginning in the preschool years. Screening examinations may be effectively performed by paramedical personnel under appropriate medical supervision. As with other specialty areas, it is important for the pediatrician to establish contact with an area ophthalmologist in the same geographical area who is familiar with children's eye problems. A close working relationship with such a specialist will clarify questions about procedures for eye screening as well as indications for referral. TIMING OF EXAMINATION AND SCREENING Children should have age-appropriate assessment for eye problems in the newborn period and at subsequent health supervision visits. Vision screening can begin as early as 3 years of age. Infants at risk for eye problems, such as retrolental fibroplasia, or those with a family history of congenital cataracts, retinoblastoma, and metabolic and genetic diseases should have an ophthalmologic examination in the nursery.

Aims and MethodThe aim of this study was to examine visual problems among patients admitted to an inner city acute mental health unit. We measured visual acuity using a Snellen chart. Patients were also asked about perceived eye problems and access to services.ResultsOf 55 in-patients on five acute general adult wards at an inner city mental health unit over a 3-day period, 31 agreed to participate in the study. Twenty (65%) had impaired visual acuity and 19 (61%) had not been to an optician for 5 or more years. Seventeen patients (55%) reported experiencing difficulty with their eyesight. The main problems reported were blurring of vision and periorbital pain. Of these 17 patients, 15 (88%) had impaired visual acuity on Snellen testing. Half of those who had previously been prescribed glasses or contact lenses reported that they had been lost.Clinical ImplicationsVisual impairment appears to be another area of physical health which is underrecognised and undertreated in people with severe mental health problems. Although there are numerous issues that must be addressed by mental health staff, patients should be asked about eye problems and supported in accessing opticians.
