Anxiety and self-consciousness in patients with minor facial lacerations

BACKGROUND: Although minor facial injuries are relatively common, their psychological impact is an area neglected in the literature. For physiologically major injuries (such as facial cancers, burns and fractures), the face has been suggested to be a psychologically significant area of the body and disfigurement has been found to have numerous potential social consequences for patients. AIMS: This paper reports the findings of an inquiry that explored the psychological impact of minor facial injuries and the influence of patient and scar characteristics in relation to self-consciousness and anxiety levels. METHOD: Data were collected in 2001 in an accident and emergency unit from patients with a visible laceration over 1.5 cm that was treatable in an outpatient setting. The Derriford Appearance Scale (with general and social self-consciousness subscales) and the State-Trait Anxiety Inventory were administered to 63 patients 1 week later; data on 50 patients were also available 6 months after the injury. RESULTS: Larger scar size, living alone and aetiology of injury were significantly related to self-consciousness and anxiety levels, although gender, age, socio-economic group, location of scar, satisfaction with appearance and number of scars were not. General self-consciousness improved at 6 months but social self-consciousness and anxiety remained the same. Patient factors were not related to changes in general self-consciousness over time. CONCLUSIONS: Minor facial scars can have significant psychological impact for some people. Awareness training for health professionals, social skills training for affected patients and a patient information leaflet are recommended.     

Sun exposure may protect against non-Hodgkin lymphoma: a case-control study

Ultraviolet radiation is a hypothesised risk factor for non-Hodgkin lymphoma (NHL) but no epidemiological study has examined this association using direct measures of sun exposure in individuals. Adults aged 20-74 years living in NSW and ACT, Australia, were the study population. Cases (704 of 829 invited to take part, 85%) were diagnosed January 2000 to August 2001. Controls (694 of 1,136 invited to take part, 61%) were randomly selected from state electoral rolls and frequency-matched to cases by age, sex and state of residence. A self-administered questionnaire and telephone interview measured outdoor hours on working and nonworking days and vacations at 10, 20, 30, 40, 50 and 60 years of age. Logistic regression models of NHL and sun exposure contained the 3 matching variables, ethnicity and sun sensitivity measures as covariates. Contrary to expectations, risk of NHL fell with increasing reported sun exposure hours. Relative to 1.0 for the lowest quarter of total sun exposure hours, the odds ratios (ORs) for successively higher quarters were 0.72 (95% CI 0.53-0.98), 0.66 (0.48-0.91) and 0.65 (0.46-0.91) (p(trend)=0.01). The association of sun exposure on nonworking days with NHL was stronger; OR for highest quarter 0.47 (0.34-0.66) (p(trend)=0.0001). Risk also fell with sun exposure on vacations; OR for highest quarter 0.60 (0.43-0.85) (p(trend)=0.003). These associations appeared strongest in women and in childhood. There was little evident trend in risk with exposure on working day. Our results provide strong statistical evidence for an inverse association between sun exposure and NHL. Increasing evidence that vitamin D may protect against cancer makes UV-mediated synthesis of vitamin D a plausible mechanism whereby sun exposure might protect against NHL.     

Spatial-frequency- and contrast-dependent visible persistence and reading disorder: no evidence for a basic perceptual deficit

Summary. The aetiology of dyslexia is still unclear, the most widely and controversially discussed theory is the magnocellular deficit hypothesis. One of the first and most influential paradigms used to investigate this visual deficit in dyslexia is the visible persistence (VP). However results on VP are decisively influenced by the method measuring VP. Lovegrove et al. (1986) repeatedly found a longer VP in reading disabled children which is significantly influenced by spatial frequency and contrast. However, these results were not investigated with the same method to date. Seventy-six unselected 2^nd grade students (41 boys, 35 girls) of a rural primary school were investigated with an identical experimental design comparable to the Lovegrove et al. (1986) studies. Comparing reading disabled (n=17) with controls (n=34) no evidence for a longer VP in the reading disabled group was found. Additionally, correlation analysis revealed no evidence for a significance of VP for spelling, phoneme awareness and speech discrimination. This study does not encourage either a magnocellular nor parvocellular deficit in dyslexia.     

Safety issues in assisted reproduction technology. A rebuttal

As part of an ongoing debate on safety in assisted reproduction, this paper supports the notion that assisted reproductive technologies must be applied responsibly, while rebutting previously expressed opinions and interpretations of history.     

Differences in reasons for smoking between younger and older smokers

The reasons why older people smoke have not been examined in the literature. This paper attempted to examine the differences in motivation and maintenance factors of elderly and young smokers using the Horn-Waingrow Why do you smoke questionnaire. One hundred and thirteen clinical patients and 112 non-patient controls were used in this study. The clinical group was divided into an elderly group (n = 58) and a younger group (n = 55). The results of a discriminant analysis showed that patients significantly differed from non-patients on 'automatic habit and stimulation', and 'crutch/tension reduction' factors. Elderly patients were found to be significantly differentiated from both younger patients and the control group on the 'pleasurable relaxation' factor. These findings offer support for the US Surgeon Generals' report that elderly smokers do have different motivating factors for their smoking behaviours from younger smokers.     

Cerebral vasospasm after subarachnoid haemorrhage of unknown aetiology: A clinical and transcranial Doppler study

Summary Sixteen patients (6 women, 10 men; mean age: 52.5 years) suffering from spontaneous subarachnoid haemorrhage (SAH) of unknown origin underwent a protocol of initial and then weekly computed tomography (CT), initial four-vessel digital subtraction angiography (DSA) and at least one control pancerebral DSA. Fourteen patients had magnetic resonance imaging before undergoing first control DSA. All patients had calcium-antagonists (Nimodipine) via a central venous catheter, were kept on the neurosurgical intensive care unit and followed daily with transcranial Doppler ultrasonography (TCD). One patient (6.3%) developed moderate and 5 (31.1%) developed severe cerebral vasospasm as documented with TCD and exhibited deterioration of their level of consciousness. These 6 patients were treated with induced hypertension, hypervolaemia and haemodilution. Their blood flow velocities were elevated for a mean of 8 (5–17) days with a peak after 12.5 (9–17) days following SAH. No complications due to treatment were noted. One patient of the non-vasospastic group died of pulmonary embolism, another patient had an ischaemic incident during angiography, which has led to permanent disability. On follow-up 2–24 months after SAH 14 patients had returned to their premorbid state. It is concluded that patients suffering from SAH of unknown origin should undergo repeated angiographic investigation and subsequent daily monitoring of their neurologic status including daily TCD recordings so that haemodynamic treatment can be established in the event of cerebral vasospasm, which may occur in up to one third of these patients.

Performance-related stress symptoms in simulated patients

INTRODUCTION: During the first 4 years of the 6-year undergraduate medical curriculum at Maastricht University, the Netherlands, students practise clinical skills in simulated patient (SP) encounters at the Skillslab. Generally, these encounters are instructive and enjoyable for both students and SPs. However, in conversations with SP trainers, some SPs have mentioned experiencing adverse symptoms due to performing a patient role. Some published studies have reported similar findings in SPs. We explored the seriousness of this problem by surveying SPs on the occurrence and severity of stress symptoms related to performing patient roles. We also examined by which variables the symptoms were influenced. METHODS: An anonymous questionnaire was developed to investigate factors related to stress symptoms and the frequency and severity of stress symptoms. A burnout scale was also included in the questionnaire. All SPs who had performed between March 2000 and March 2001 were asked to participate. RESULTS: The response rate was 84%. Of the SPs, 73% were found to have experienced stress symptoms, with a mean of 4 symptoms per SP. No significant correlations were found between the occurrence of symptoms on the one hand and factors that might influence symptoms or the burnout scale on the other hand. DISCUSSION: An unexpectedly high number of SPs reported symptoms. Fortunately, the symptoms were relatively mild (2.2 on a 5-point scale). Future studies should address the connection between work as an SP and symptoms, and measures should be taken to prevent and treat the symptoms. Debriefing sessions might play a role in this respect.     

Changes in causes of low vision between 1988 and 2009 in a Dutch population of children

Purpose: Causes of low vision in the Netherlands may have changed over time. The purpose of this study is to assess trends over the last two decades. Methods: Socio‐demographic and medical data, including ophthalmic diagnosis and inheritance patterns for 2843 children with low vision (0–21 years; 50% representation) referred to a Dutch institute for low vision (Bartiméus) over a 21‐year period between 1988 and 2009, were included in the analysis. For the 19 most common diagnoses, inheritance and presence of mental impairment, trend analyses were performed with logistic regression models; odds ratios (OR) for a 10‐year time span were reported. Results: Cerebral visual impairment (CVI) was found in 27.2% (97% mental impairment), albinism in 8.0%. Over time, nystagmus (6.6%; OR = 1.42), retinitis pigmentosa (2.9%; OR = 1.61), cone‐rod dystrophy (2.6%; OR = 1.98) and hyperopia (2.0%; OR = 3.66) increased significantly. Cataract (4.9%; OR = 0.64), aniridia (1.6%; OR = 0.42) and retinopathy of prematurity (ROP; 2.0%; OR = 0.45) decreased significantly. There was a significant increase in genetic disorders (41.0%; OR = 1.49) and in co‐occurrence of mental impairment (52.2% OR = 1.16). Conclusion: In the last two decades, treatable or preventable disorders (such as cataract and ROP) have become a less common cause of low vision in children. However, the prevalence of complex (genetic) and untreatable disorders (CVI) has taken its place, as a result of increased survival of preterm and low birth weight children and improved diagnostic possibilities. Knowledge of the prevalence of low vision, its causes and trends over time may help policy makers to define effective intervention strategies and to monitor its impact.
