Psychosocial factors related to long-term survival with HIV/AIDS

Only a few studies of long-term survivors of AIDS (those who survive more than twice the median expected time) have been done but these reveal a constellation of psychological characteristics including, but not limited to, those with active coping, social support, life involvement, ability to communicate, and active collaboration with one's doctor. Another related literature consists of longitudinal studies following people infected with the HIV virus to determine whether psychological characteristics are related to disease progression. These studies have focused on coping, depression, negative expectancies and social support as predictors. This article reviews and integrates the two bodies of literature combining the variables identified into four psychosocial strategies related to longer survival with HIV/AIDS: following healthy self care; maintaining connectedness; having a sense of meaning or purpose in life; and maintaining perspective. Affect, beliefs, and behaviour are all seen as important. Biological variables, SES and psychological resources that the person brings to the situation and external stresses are seen as important variables to consider in prediction studies. The pathways through which these four strategies may operate (both psychological and biological) to impact on health are discussed. Psychological pathways include distress and behavioural disengagement, while biological pathways involve the sympathetic nervous system, neuroendocrine and immune mediation. Finally suggestions for future research are given.     

Normal cerebrospinal fluid pressure in the newborn

Lumbar CSF pressure (CSFP) was measured on 61 occasions, in 49 babies undergoing lumbar puncture as part of a septic screen, by means of Gaeltec pressure transducers. In normal circumstances, intracranial pressure (ICP) has the same value. Measurements were made when the baby was horizontal and quiet, with the head deflexed. For acceptance of the measurement, it was essential for the CSF to be clear and to show pressure pulses with respiration, heartbeat and jugular occlusion. The mean CSFP and standard deviation were 2.8 +/- 1.4 mm Hg (3.8 +/- 1.9 cm water), with a normal range of 0 to 5.7 mm Hg (0 to 7.6 cm water). This value is similar to previous reports of CSFP measured invasively in infants, but is much lower than the "ICP" established noninvasively. No relationship was found between birthweight, gestational age, current weight, postmenstrual age, or postnatal age and CSFP.

Total Hip Arthroplasty in Patients With Osteoarthritis Associated With Legg-Calve-Perthes Disease: Perioperative Complications and Patient-Reported Outcomes

BackgroundComplications and patient-reported outcomes (PROs) of total hip arthroplasty (THA) in patients with Legg-Calve-Perthes disease (LCPD) have demonstrated variable results. The purpose of this study was to use a validated grading scheme to analyze complications associated with THA in patients with residual LCPD deformities. Second, we report PROs and intermediate-term survivorship in this patient population.MethodsA retrospective, single-center review was performed on 61 hips in 61 patients who underwent THA for residual Perthes disease. Average patient age was 42 years and 26% of hips had previous surgery. Complications were determined and categorized using a validated grading scheme that included five grades based on the treatment required to manage the complication and on persistent disability. PROs were compared from preoperative to most recent follow-up time points.ResultsMajor complications (grade III) occurred in three patients (5%) which each required a second surgical intervention. The most common minor grade I or II complications (11.5%) were asymptomatic heterotopic ossification (3.3%). Patients were lengthened on the surgical side an average of 1.4 cm with no nerve palsies. All patient PROs improved from preoperative to postoperative time points with the modified Harris Hip Score improving from 46.9 preoperatively to 85.4 postoperatively (P < .01). Patients free from revision for any reason at final follow-up (5.6 years; range 2-13 years) was 98.4% with one patient needing a revision of their femoral component.ConclusionsTHA for the sequelae of the LCPD has an acceptable complication rate and provides excellent patient reported outcomes at mid-term follow-up.     

Spinal anaesthesia but not general anaesthesia enhances neutrophil biocidal activity in hip arthroplasty patients

The purpose of this study was to compare neutrophil cidal activity during general or spinal anaesthesia. Assays were performed on neutrophils extracted from the blood of patients after surgery had been under way for one hour. First, the ability of the neutrophils to kill a standard laboratory strain of S. aureus was examined. Neutrophils extracted from the blood during surgery in the spinal anaesthetic group and incubated with the staphylococci for one hour killed twice as many bacteria than those from two groups of patients that received halothane or isoflurane general anaesthesia (P < 0.05). This effect persisted, to a lesser extent, in the spinal group neutrophils after two hours of incubation with the bacteria. Second, neutrophils from patients under the same conditions of surgery and anaesthesia were tested to examine the effect of the different anaesthetic techniques on neutrophil biocidal mechanisms. Neutrophils extracted during surgery in the spinal group released more superoxide in response to phorbol-12-myristate-13-acetate (PMA) than those from both groups of patients that received general anaesthesia (P < 0.05). It is concluded that there is an increased state of reactivity of the neutrophil cell membrane NADPH oxidase system in patients receiving spinal anaesthesia than in patients receiving general anaesthesia.     

Relating health education research to health policy

This paper argues that research in health education is being driven by a set of implicit values that emphasize formality, rigor and objectivity, and that relatively little attention is being paid to the ways in which research findings are subsequently used. A critique of a detached and formal research perspective is developed around the problems of 'pure' knowledge and the potential incompatibility between this and policy-making processes. In this light, it is suggested that the pursuit of academic research rigor at the expense of practical utility is hindering the development of a stronger research-policy link. The paper then goes on to suggest that in adopting a sharper political orientation, health education research could legitimately become less concerned with the restrictive nature of academic formalism with research. The nature of this type of research, the potential it has as well as its limitations are subsequently explored.     

Manic Psychosis and Catatonia Stemming from Systemic Lupus Erythematosus: Response to ECT

A 27-year-old woman with severe psychosis and mania associated with systemic lupus erythematosus was successfully treated with electroconvulsive therapy. Cyclophosphamide was given as an adjuvant. The use of electroconvulsive therapy in patients with lupus and psychiatric disorders is discussed.     

Assessment issues involving the families of trauma victims

This paper reviews the empirical literature on the clinically significant problems found within families containing a member with post-traumatic stress disorder. Recommendations are made regarding specific instruments that can be useful for evaluating marital and familial adjustment. Assessment issues concerning the need to weigh historical relationship factors vis-á-vis the influences of a traumatized family member are discussed. A multiple-gating model is presented for assessing different aspects of family dysfunction, and suggestions for future research and clinical directions are offered.
