An intraoperative irrigation regimen to reduce the surgical site infection rate following adolescent idiopathic scoliosis surgery.

INTRODUCTION: The aim of this study was to compare the efficacy of a gentamicin antibiotic intraoperative irrigation regimen (regimen A) with a povidone-iodine intraoperative irrigation regimen (regimen B) and to evaluate the ability of adjunctive local vancomycin powder (regimen C) to reduce the surgical site infection (SSI) rate following idiopathic scoliosis correction. METHODS: This was a retrospective, single centre, two-surgeon cohort study of paediatric scoliosis procedures involving 118 patients under the age of 18 years who underwent correction for idiopathic scoliosis over a period of 42 months. Patients' baseline characteristics, pseudarthrosis and rates of SSI were compared. RESULTS: Baseline characteristics were comparable in all three groups, with the exception of sex distribution. Over a quarter (27%) of patients with regimen B were male compared with 13% and 6% for regimens A and C respectively. Patients were mostly followed up for a minimum of 12 months. The SSI rate for both superficial and deep infections was higher with regimen A (26.7%) than with regimens B and C (7.0% and 6.3% respectively). The SSI rates for regimens B and C were comparable. No patients developed complications related to vancomycin toxicity, metalwork failure or pseudarthrosis. CONCLUSIONS: Wound irrigation with a povidone-iodine solution reduces SSIs following adolescent idiopathic scoliosis surgery. The direct application of vancomycin powder to the wound is safe but does not reduce the SSI rate further in low risk patients. Additional studies are needed to elucidate whether it is effective at higher doses and in high risk patient groups.

Survey of campylobacter, salmonella and mycoplasmas in house crows (Corvus splendens) in Malaysia.

House crows (Corvus splendens) in Selangor, Malaysia were examined for the presence of Campylobacter species, Salmonella species, Mycoplasma gallisepticum and Mycoplasma synoviae by serology, culture and pcr. For the detection of Campylobacter and Salmonella species swabs were taken either from the intestine or cloaca. For the detection of mycoplasmas, swabs were taken either from the choanal cleft or trachea for culture and pcr and serum samples were tested by the rapid serum agglutination (rsa) and monoclonal antibody-blocking elisa (mbelisa) for antibodies to M gallisepticum and M synoviae. For campylobacter, 25.3 per cent of the crows were positive by culture, and the species identified were Campylobacter jejuni and Campylobacter coli. No Salmonella species were isolated. Four of 24 swabs were positive for M gallisepticum dna but none gave positive results for M synoviae dna. No M gallisepticum or M synoviae antibodies were detected by rsa but 60 per cent of the sera gave positive reactions for M gallisepticum and 13 per cent gave positive reactions for M synoviae by mbelisa.

Does topical GTN on the sphincter of Oddi facilitate ERCP? A double-blind randomized control trial.

BACKGROUND: Endoscopic retrograde cholangio pancreatography (ERCP) is a technically challenging procedure. Glyceryl trinitrate (GTN) has been shown to reduce tone in the sphincter of Oddi (SO), cannulation of which is a rate-limiting factor. A double-blind randomized control trial was performed to assess whether topical GTN on the SO would facilitate cholangiography and/or bile duct cannulation. METHODS: 104 patients requiring ERCP for biliary symptoms were randomized into two groups, 52 controls pretreated with 5 ml 0.9% normal saline (NS) and 52 pretreated with 5 ml GTN (concentration 1 mg/ml). RESULTS: There was no significant between the control group and the GTN group in primary cannulation rate (p = 0.76), time taken to cholangiography (p = 0.58), or time to cannulation (p = 0.43). CONCLUSION: Topically administered GTN to the SO does not aid in obtaining a cholangiogram or cannulation during an ERCP.

Psychological therapies for adults with anorexia nervosa: randomised controlled trial of out-patient treatments.

BACKGROUND: Currently, without systematic evidence, psychotherapy for anorexia nervosa in adults draws on psychodynamic, cognitive and systemic theories. AIMS: To assess effectiveness of specific psychotherapies in out-patient management of adult patients with anorexia nervosa. METHOD: Eighty-four patients were randomised to four treatments: three specific psychotherapies - (a) a year of focal psychoanalytic psychotherapy; (b) 7 months of cognitive-analytic therapy (CAT); (c) family therapy for 1 year - and (d) low contact, 'routine' treatment for 1 year (control). RESULTS: At 1 year, there was symptomatic improvement in the whole group of patients. This improvement was modest, several patients being significantly undernourished at follow-up. Psychoanalytic psychotherapy and family therapy were significantly superior to the control treatment; CAT tended to show benefits. CONCLUSIONS: Psychoanalytic and family therapy are of specific value in the out-patient treatment of adult patients with anorexia.

Detection of Mycoplasma synoviae in clinically normal pheasants.

Mycoplasma synoviae was isolated from the tracheas of seven clinically normal pheasants found in the vicinity of a chicken farm infected with M synoviae, but not from 120 pheasants and partridges with respiratory disease. When specimens were examined by the polymerase chain reaction only two additional pheasants infected with M synoviae were identified, one healthy and one diseased.

Mycoplasmas and respiratory disease in pheasants and partridges.

Pheasants and partridges with signs of upper respiratory disease were cultured for mycoplasmas and were also examined for Mycoplasma gallisepticum and Mycoplasma synoviae using commercial polymerase chain reaction (PCR) kits. Sixty-two incidents of disease were investigated in pheasants and 12 in partridges. M. gallisepticum was detected by culture in only four and three incidents in pheasants and partridges, respectively, but with PCR a further 15 M. gallisepticum-positive incidents were detected in pheasants and another five in partridges. Several fast-growing Mycoplasma species, in particular Mycoplasma glycophilum, Mycoplasma gallinaceum and Mycoplasma pullorum, were isolated frequently and were thought to be impeding the isolation of M. gallisepticum by outgrowing it. Samples yielding M. gallisepticum isolates contained significantly fewer "contaminating" species and were exclusively from specimens submitted as whole heads rather than as swabs or as cultures from other laboratories. M. synoviae was not isolated and was detected in only one specimen by PCR.

Family therapy for adolescent anorexia nervosa: the results of a controlled comparison of two family interventions.

This paper reports the results of a randomised treatment trial of two forms of outpatient family intervention for anorexia nervosa. Forty adolescent patients with anorexia nervosa were randomly assigned to "conjoint family therapy" (CFT) or to "separated family therapy" (SFT) using a stratified design controlling for levels of critical comments using the Expressed Emotion index. The design required therapists to undertake both forms of treatment and the distinctiveness of the two therapies was ensured by separate supervisors conducting live supervision of the treatments. Measures were undertaken on admission to the study, at 3 months, at 6 months and at the end of treatment. Considerable improvement in nutritional and psychological state occurred across both treatment groups. On global measure of outcome, the two forms of therapy were associated with equivalent end of treatment results. However, for those patients with high levels of maternal criticism towards the patient, the SFT was shown to be superior to the CFT. When individual status measures were explored, there were further differences between the treatments. Symptomatic change was more marked in the SFT whereas there was considerably more psychological change in the CFT group. There were significant changes in family measures of Expressed Emotion. Critical comments between parents and patient were significantly reduced and that between parents was also diminished. Warmth between parents increased.

The assessment of expressed emotion in a standardised family interview.

This study compared the expressed emotion (EE) scores obtained using individual interviews with parents with the scores obtained in whole family interviews. Interviews were carried out with 31 parents of 16 adolescents referred because of an eating disorder. There was moderate correlation of scores between the two interviews regarding critical comments, emotional overinvolvement, and warmth, but it was low for positive remarks. The study suggests that the whole family interview, which is time saving, is useful in assessing expressed emotion. The levels of expressed emotion, particularly the relatively low levels of critical comments and emotional overinvolvement, are similar to those of previous studies.

Family and individual therapy in anorexia nervosa. A 5-year follow-up.

BACKGROUND: There is evidence that specific psychological treatments are effective in patients with eating disorders. Our goal was to determine by means of a controlled trial whether psychological treatments, previously found to be effective in anorexia nervosa, gave rise to enduring benefits. METHODS: A 5-year follow-up was conducted on patients who had participated in a previous trial of family therapy for anorexia and bulimia nervosa. Family therapy or individual supportive therapy had been administered to 80 outpatients for 1 year beginning on discharge from hospital after weight restoration. The 80 patients had been subdivided into 4 prognostically homogeneous groups of which 2 turned out to be the most important: patients with early onset and short history of anorexia nervosa, and patients with late-onset anorexia nervosa. At the 5-year follow-up, the efficacy of the outpatient therapies was again assessed by the maintenance of weight, and the categories of general outcome and dimensions of clinical functioning defined by the Morgan-Russell scales. RESULTS: Significant improvements were found in the group of 80 patients as a whole, mainly attributable to the natural outcome of anorexia nervosa, and most evident in the early onset and short history group, as expected. Within 2 of the prognostic groups, significant benefits attributable to previous psychological treatments were still evident, favoring family therapy for patients with early onset and short history of anorexia nervosa and favoring individual supportive therapy for patients with late-onset anorexia nervosa. CONCLUSIONS: Much of the improvements found at a 5-year follow-up can be attributed to the natural outcome of the illness. Nevertheless, it was still possible to detect long-term benefits of psychological therapies completed 5 years previously.

Redefining the psychosomatic family: family process of 26 eating disorder families.

This paper reports part of the data from a comparative trial of two forms of family intervention for the management of eating disorders in adolescents. Measures of family process at the beginning of treatment included Expressed Emotion (EE) and the Family Adaptability and Cohesion Evaluation Scales (FACES). EE in the families of both anorexic and bulimic patients were, on the whole, at low levels. The low levels of parental Critical Comments might be taken to represent the conflict avoiding character of the families of psychosomatic patients. However, the families showed low levels of Emotional Overinvolvement, which contradicts the clinical descriptions. The FACES scores revealed patterns that were superficially contradictory to the accepted clinical descriptions in that the patients appeared to have perceived their families as not close and as highly structured. The parents experienced their family structure as more similar to the clinical descriptions, scoring their families as more flexible and cohesive than do the patients. The FACES ideals for family organization scored by patients and parents more nearly equate with the clinical descriptions of enmeshment and lack of boundary structure. The relationship between the research findings and the clinical evaluation will be discussed.

The effects of tick-borne fever on the susceptibility of ovine polymorphonuclear cells to P. haemolytica cytotoxin.

Tick-borne fever predisposes sheep to secondary infections by Pasteurella haemolytica. Polymorphonuclear (PMN) cells obtained from sheep 2 to 7 days after the onset of parasitaemia due to Cytoecetes phagocytophila, the causative agent of tick-borne fever, were significantly more susceptible in vitro to the cytotoxin of P. haemolytica than PMN obtained from age-matched control sheep.

Purification of Cytoecetes phagocytophila, the causative agent of tick-borne fever, from infected ovine blood.

Cytoecetes phagocytophila, the causative agent of tick-borne fever, was successfully separated by Percoll and Renografin density gradient centrifugation and by cellular affinity chromatography, from the peripheral blood leucocytes of experimentally infected sheep. After centrifugation on Renografin or Percoll density gradients, infectious particles of C. phagocytophila banded at buoyant densities which ranged between 1.063 to 1.140. Rickettsiae separated by wheat germ lectin cellular affinity chromatography retained their morphology but often lost their infectivity. Cell-free C. phagocytophila remained infective to susceptible sheep for 6 months when kept at -114 degrees C in sucrose phosphate buffer with 10 per cent dimethylsulphoxide as a cryopreservative.

An evaluation of family therapy in anorexia nervosa and bulimia nervosa.

A controlled trial comparing family therapy with individual supportive therapy in anorexia nervosa and bulimia nervosa was undertaken. Eighty patients (57 with anorexia nervosa; 23 with bulimia nervosa) were first admitted to a specialized unit to restore their weight to normal. Before discharge, they were randomly allocated to family therapy or the control treatment (individual supportive therapy). After one year of psychological treatment, they were reassessed, using body weight, menstrual function, and ratings on the Morgan and Russell scales. Family therapy was found to be more effective than individual therapy in patients whose illness was not chronic and had begun before the age of 19 years. A more tentative finding was the greater value of individual supportive therapy in older patients. To our knowledge, this is the first controlled trial of family therapy in anorexia nervosa and clarifies the specific indications for this treatment.

Expressed emotion in individual and family settings: a comparative study.

Expressed emotion ratings were performed, in two separate settings, on the parents of 20 children suffering from anorexia nervosa. Ratings were made on conventional individual interviews and on videotapes of a family interview. Comparison of ratings in the two settings showed a very high correlation for 'critical comments'. Findings on the other scales were harder to interpret, but significant correlations as well as differences were noted. Expressed emotion rated in family interviews provides new possibilities for the study of families.

Important problems identified by patients with chronic arthritis.

To assess the impact of their illness on their whole life experience 345 patients with chronic arthritis were interviewed and completed a questionnaire. Four major sub-groups were identified--rheumatoid arthritis, gout, ankylosing spondylitis and osteo-arthritis. Taking into account definite inter-group differences, the commonest problems were pain (65%), stiffness (61%), inability to do everyday tasks (43%) and sexual difficulties (31%). The implications these problems raise in clinical practice are discussed and some suggestions for a rehabilitation programme made.
