Psychological and social factors in reconstructive surgery for hemi-facial palsy.

This paper examines the psychological and social impact of reconstructive surgery for hemi-facial palsy and considers psychosocial factors which may be associated with patient satisfaction. It reports a retrospective study in which 106 adults were assessed using primarily qualitative methods. All participants had undergone two-stage reconstruction using vascularised free muscle grafts, with all procedures having been carried out by the same surgeon. The participants were all at least 12 months post-surgery. They were assessed using demographic questionnaires, the hospital anxiety and depression scale (HADS) and the facial paralysis evaluation measure (FPEM). In addition, all participants were interviewed using a semi-structured format, the interviews were recorded verbatim and the transcripts were analysed using thematic analysis. Of the total study group, 67% had acquired facial palsy. The mean age of the total group was 44.7 years and 67.9% were female. As a group they were rather less depressed than the normal population with similar levels of anxiety to population norms. The primary motivation for surgery was appearance rather than function. Using interview data in addition to the FPEM, satisfaction with the process and outcome of surgery was assessed. Thirty five percent were very satisfied with both process and outcome, 34% were satisfied with the outcome but found the treatment process stressful, 15.1% were not entirely satisfied with process or outcome but felt surgery had been worthwhile as there had been some improvement. The remainder were very dissatisfied with both process and outcome and regretted having undergone surgery. There was no significant association between dissatisfaction and anxiety, the cause of the acquired palsy, longevity prior to surgery, gender nor whether the condition was acquired or congenital. There was a significant relationship with depression, in that those who were suffering from depression were more likely to be dissatisfied with surgery. Participants were asked in interview about social pressures and comments or remarks made by others about their condition. The majority (89.6%) of the total study group reported intrusive questions by acquaintances and strangers, with more than half of these being distressed by such questions. Following surgery, there was a significant reduction in the incidence of these questions. There was no relationship between distress in response to these questions prior to surgery and dissatisfaction with surgery. However, 27.4% also reported aggressive hurtful comments before surgery with a minimal improvement in incidence following surgery. These participants also reported consistent patterns of social avoidance and social isolation before and after surgery, and were more likely to be depressed than the rest of the study group. They were significantly more likely to be dissatisfied with surgery (p=.016). It is recommended that patients are screened and counseled prior to surgery to identify such problems and referred for psychological treatment in order to ensure they gain maximum benefit from reconstructive surgery.

Cost-benefit model comparing two alternative immunisation programmes against serogroup C meningococcal disease: for Quebec residents aged 2 months to 20 years.

OBJECTIVE: To evaluate the most efficient approach to managing an outbreak of serogroup C meningococcal disease. An early planned mass immunisation programme (MIP) was compared with a delayed programme implemented at the peak of a meningococcal outbreak. DESIGN AND SETTING: A cost-benefit model was constructed of meningococcal cases reported in Quebec, Canada, from 1990-1993, before and after the MIP, during the winter of 1992-1993, when 84% of residents aged 6 months to 20 years were vaccinated. Epidemiological data from 1990-1993 were transposed to 2002-2003 under the assumption that Quebec is on the brink of an identical outbreak cycle. All Quebec residents aged 2 months to 20 years were assumed to be vaccinated, which required a total of 1.7 million doses of conjugated vaccine. Clinical and economic outcomes of both vaccination scenarios were compared. All costs were transformed to 2001 Canadian dollars ($Can), at an annual inflation rate of 3%. Future earnings due to premature death were discounted at 5% per year with a 3% increase in wages per year and a 9% unemployment rate. PERSPECTIVE: Ministry of Health and society. MAIN OUTCOME MEASURES: The number of new cases avoided and the prevention of hospital and societal costs due to meningococcal disease-attributed premature mortality and morbidity, and direct costs associated with implementation of a MIP. RESULTS: When compared with a delayed MIP over a 14-month period, an early planned MIP would have prevented 112 new cases of meningococcal disease (16 deaths, 21 major complications) while saving $ Can 37.1 million in total direct costs to the Ministry of Health and an additional $ Can 17.4 million in societal costs in the province of Quebec. CONCLUSION: An early planned MIP implemented in Quebec in September 2001, should be cost beneficial compared with delaying mass immunisation until a meningococcal outbreak is underway. Although this conclusion is limited by the assumption that epidemiological trends in 2001 in absence of a MIP would have been similar to that observed in the early 1990s prior to the MIP, the analysis still indicates that an early MIP in the 1990s would have been cost beneficial compared with a delayed MIP.

Assessing pain in elderly patients who cannot respond verbally.

Many patients cannot respond verbally and there is noted to be an increase in disorientation and confusional states in advanced age. The problem of pain assessment for this group is therefore not only a large problem but potentially a growing one. A pilot study was carried out to validate a chart for the assessment and control of pain using observed pain behaviours. The researchers studied elderly patients with a variety of medical problems on three wards. The study was done by observing pain behaviours, carrying out pain intervention and re-observing later to verify the effectiveness or otherwise of the intervention. If this had been successful in moderating the behaviours it could reasonably be inferred that a method of monitoring and comforting verbally unresponsive patients had been found.

Differentiation of human motion data using combined spline and least squares concepts.

A differentiation method, which combines the concepts of least squares and splines, has been developed to analyze human motion data. This data smoothing technique is not dependent on a choice of a cut-off frequency and yet it closely reflects the nature of the phenomenon. Two sets of published benchmark data were used to evaluate the new algorithm.

The incidence and outcome of asymptomatic herpes simplex genitalis in an obstetric population.

In a prospective study of an obstetric population, 28 of 488 (4%) routine asymptomatic patients had positive cultures for herpes simplex virus from their genital tract. Cesarean section was carried out if the virus was present in the genital tract at the time of delivery. In one instance, a culture which had reverted to negative became positive again. No cases of neonatal herpes were reported in the time of the study. As yet, the infectivity of these subclinical cases is unclear, and the incidence of neonatal herpes is not as high as would be expected from the study. Further studies need to be carried out to evaluate the exact risk of the asymptomatic herpesvirus shedder to the infant at birth.
