Loop colostomy formation commonly involves temporary support over a plastic bridge. We describe a technique of loop colostomy using a permanent skin bridge. By joining two inter-digitating skin flaps raised from the margins of the stoma, an adjustable bridge is formed that can accommodate colon loops of any diameter. In a series of twenty cases, our technique has been complication free and well tolerated by patients.
A survey was made of the prevalence, diagnosis and treatment of dermatological conditions in small animals in general practice in the UK. Out of 3707 small animal consultations in general practice that were observed and recorded, 795 (21.4 per cent) involved animals that had a dermatological problem. In dogs and exotic species, pruritus was the most common presenting sign, accounting for 30 to 40 per cent of the dermatological consultations. In cats, cutaneous swellings were the most common presentation (36 per cent). A diagnosis or recommendation for treatment was made on the basis of the presenting clinical signs and physical examination alone in 576 (72 per cent) of the cases, and various diagnostic tests were performed in the other cases. In dogs, parasitic infestations, bacterial infections and neoplasia accounted for the majority of the diagnoses. In cats, parasites and bacterial infections were the most common. In exotic species, parasites accounted for over 80 per cent of the dermatological diagnoses. In dogs, the most common final diagnoses were otitis, pyoderma, anal sac impaction, flea infestation and atopic dermatitis. In cats, abscesses, flea infestation, and otitis were the most common diagnoses. In exotic species, the most common diagnosis was an unspecified mite infestation. Systemic antibiotics were prescribed in 196 cases (25 per cent), systemic glucocorticoids were prescribed in 162 cases (20 per cent) and treatment with an ectoparasiticide was prescribed in 167 cases (21 per cent).
BACKGROUND: Urinary incontinence can affect 40-60% of people admitted to hospital after a stroke, with 25% still having problems on hospital discharge and around 15% remaining incontinent at one year. OBJECTIVES: To determine the optimal methods for prevention and treatment of urinary incontinence after stroke in adults. SEARCH STRATEGY: We searched the Cochrane Incontinence and Stroke Groups specialised registers (searched 15 December 2004 and 26 October 2004, respectively), CINAHL (January 1982 to November 2004), national and international trial databases for unpublished data, and the reference lists of relevant articles. SELECTION CRITERIA: Randomised or quasi-randomised controlled trials evaluating the effects of interventions designed to promote continence in people after stroke. DATA COLLECTION AND ANALYSIS: Data extraction and quality assessment were undertaken by two reviewers working independently. Disagreements were resolved by a third reviewer. MAIN RESULTS: Seven trials with a total of 399 participants were included in the review. Participants were from a mixture of settings, age groups and phases of stroke recovery. No two trials addressed the same comparison. Four trials tested an intervention against usual care, including acupuncture, timed voiding, and two types of specialist professional intervention. One cross-over trial tested an intervention (oestrogen) against placebo. One trial tested a specific intervention (oxybutynin) against another intervention (timed voiding), and one trial tested a combined intervention (sensory-motor biofeedback plus timed voiding) against a single component intervention (timed voiding alone). Reported data were insufficient to evaluate acupuncture or timed voiding versus usual care, oxybutynin versus timed voiding, or sensory motor biofeedback plus timed voiding versus usual care. Evidence from a single small trial suggested that structured assessment and management of care in early rehabilitation may reduce the number of people with incontinence at hospital discharge (1/21 versus 10/13; RR 0.06, 95% CI 0.01 to 0.43), and have other benefits. Evidence from another trial suggested that assessment and management of care by Continence Nurse Practitioners in a community setting may reduce the number of urinary symptoms (48/89 versus 38/54; RR 0.77, 95% CI 0.59 to 0.99), and increase satisfaction with care. AUTHORS' CONCLUSIONS: There was suggestive evidence that specialist professional input through structured assessment and management of care and specialist continence nursing may reduce urinary incontinence after stroke. Data from trials of other physical, behavioural, complementary and anticholinergic drug interventions are insufficient to guide continence care of adults after stroke.
BACKGROUND: General practitioners (GPs) can be provided with effective training in the skills to manage depression. However, it remains uncertain whether such training achieves health gain for their patients. METHOD: The study aimed to measure the health gain from training GPs in skills for the assessment and management of depression. The study design was a cluster randomized controlled trial. GP participants were assessed for recognition of psychological disorders, attitudes to depression, prescribing patterns and experience of psychiatry and communication skills training. They were then randomized to receive training at baseline or the end of the study. Patients selected by GPs were assessed at baseline, 3 and 12 months. The primary outcome was depression status, measured by HAM-D. Secondary outcomes were psychiatric symptoms (GHQ-12) quality of life (SF-36), satisfaction with consultations, and health service use and costs. RESULTS: Thirty-eight GPs were recruited and 36 (95%) completed the study. They selected 318 patients, of whom 189 (59%) were successfully recruited. At 3 months there were no significant differences between intervention and control patients on HAM-D, GHQ-12 or SF-36. At 12 months there was a positive training effect in two domains of the SF-36, but no differences in HAM-D, GHQ-12 or health care costs. Patients reported trained GPs as somewhat better at listening and understanding but not in the other aspects of satisfaction. CONCLUSIONS: Although training programmes may improve GPs' skills in managing depression, this does not appear to translate into health gain for depressed patients or the health service.
OBJECTIVES: Campylobacter jejuni enteritis can lead to musculoskeletal, neuropathic or other health sequelae. We investigated the coexistence, seasonal occurrence, strain-type associations and impact on work capacity of different health problems following C. jejuni enteritis in a Lancashire population during 1999 and 2001. METHODS: A semistructured questionnaire was used to characterize health problems that occurred in the community after laboratory-confirmed episodes of C. jejuni enteritis. The questionnaire was posted to all adults in the Preston and Chorley area who developed C. jejuni enteritis in 1999 or 2001. All Campylobacter isolates from this population were serotyped. RESULTS: Several types of sequelae occurred consistently in both years, including the coexistence of musculoskeletal and neuropathic problems. There was no evidence of C. jejuni strain-type associations or seasonal preponderance for any type of sequela. The overall health impact of C. jejuni enteritis, as measured by workdays lost, was high in this population. CONCLUSIONS: A variety of health problems occur consistently following C. jejuni enteritis and substantially increase morbidity due to campylobacteriosis in the community.

INTRODUCTION: Lateral sphincterotomy is now the standard surgical treatment for fissure-in-ano. Healing is achieved in 90% of cases, however, sphincterotomy also carries a significant risk of incontinence. Traditional sphincterotomy comprises of division of the internal sphincter up to the level of the dentate line, a more conservative division could lead to a lower incontinence rate, with an equivalent healing rate. MATERIALS AND METHODS: A total of 65 patients undergoing conservative lateral sphincterotomy under a single operator between January, 1996 and January, 2002 were reviewed. Specific questions were asked regarding overall success of the operation, leakage of fluid, faeces or flatus and recurrence of fissure symptoms. Supplemental data was obtained from a retrospective analysis of the patients' case notes to ascertain demographics, length of hospital stay and complication rate. RESULTS: Sixty of 65 patients responded to our postal questionnaire. The male to female ratio was 1:1 and the mean age 40.3 years of age. No complications were recorded and 97% of patients had achieved fissure healing by the time of their out-patient follow-up (mean 6.9 weeks). Two patients reported new incontinence following their procedure; one patient experienced incontinence of fluid and flatus (1.7%) and the remaining patient complained of incontinence to flatus only. No patients experienced incontinence of faeces. Eleven patients experienced persistent symptoms of pain and bleeding but only 6 of these patients required treatment from their general practitioner which consisted of stool softeners and topical analgesia. No patients required re-operation. CONCLUSION: A conservative division of the internal anal sphincter results in adequate fissure healing and a much lower incontinence rate than that previously recorded in the literature for more traditional divisions of the internal anal sphincter.
The most common surgical treatment for fibroids is hysterectomy and approximately 30,000 are carried out annually in the UK for this condition. The operation, however, carries a significant complication rate. Since the first case was carried out in 1989 there has been increasing interest in the interventional radiological procedure called fibroid embolization where angiographic techniques are used to occlude the vascular supply of fibroids. This article is a review of the world experience of fibroid embolization, its development, techniques, indications, results and complications. So far evidence indicates very promising mid-term results but more long-term comprehensive data is needed from large trials.
The booster effect varies between populations, but has not been studied in the UK. The aim of this study was to investigate the effect of repeat tuberculin tests at 1 wk in BCG-vaccinated healthy subjects (all hospital employees) in the UK; we have assessed whether a booster effect is present 48 and 72 h after injection. Twenty-six subjects received two tuberculin tests (both 10 units) administered by the Mantoux technique-Tests 1 and 2. At Test 2 there was a significant increase in induration at 48 h (mean, 7.8 mm; p < 0.001), no difference at 72 h (mean, 0.2 mm; p = 0.93), and a reduction at 96 h (mean, -4.2 mm; p = 0.02). There were more positive results (> 15 mm induration) at Test 2 compared with Test 1 at 48 h (19 vs. 9, respectively; p = 0.002), but similar numbers at 72 h (11 vs. 10, respectively). These results show that repeat tuberculin testing in this BCG-vaccinated population caused a booster effect that varied with the time of measurement and was maximal at 48 h.

Forty patients due to undergo endometrial ablation as a treatment for dysfunctional uterine bleeding were recruited to assess the efficacy and safety of endometrial laser intrauterine thermo-therapy using the gynelase. At 12 months the average menstrual score reduction was 88%, the amenorrhoea rate was 70%, and the hypomenorrhoea rate 16%. Four women (10%) have had a hysterectomy for persistent menorrhagia, and one (3%) for pelvic pain. One patient (3%) has had a further endometrial laser ablation. There were no major complications. and 34 patients (85%) were most satisfied with the treatment. The system is easy to use and has a short learning curve.
OBJECTIVES: To assess the long term outcome of laparoscopic supracervical hysterectomy. DESIGN: Retrospective study. SETTING: Minimal Access Surgical Unit, Department of Gynaecology, Royal Surrey County Hospital, Surrey. METHODS: Analysis of patient case records. POPULATION: Seventy consecutive women who had a laparoscopic supracervical hysterectomy. OUTCOME MEASURES Symptoms related to the cervical stump and the need for further surgery. RESULTS: The mean time of patient follow up was 66 months (range 52-84). The mean time from initial procedure to second treatment was 14 months (range 3-53). Seventeen women (24.3%) reported symptoms related to the cervical stump, and all required further surgery. The cervical stump was removed in 16 (22.8%). One patient had laparoscopic adhesiolysis only and two had a laparotomy and trachelectomy because the bowel was adherent to the cervical stump. Nine had a laparoscopically assisted cervical trachelectomy as the sole procedure. Five had laser treatment to endometriotic deposits, and laparoscopically assisted cervical trachelectomy. Histological analysis showed normal cervical tissue in six (35.3%). Endometriosis was detected in four cervical stumps (23.5 %), residual endometrium in another four (23.5 %) cases, and chronic cervicitis, mild CIN and a mucocoele in a further three patients. Of the 17 women who reported cervical stump symptoms, 14 (82.3%) had been treated for endometriosis in the past, compared with 17/53 (32%) who did not have symptoms (P < 0.0002, chi2 test). CONCLUSIONS: Symptoms related to the cervical stump requiring further surgery frequently occur following a laparoscopic supracervical hysterectomy.

This paper describes the efforts of the faculty of the Family Institute of New Jersey in recent years to develop a collaborative family training program that takes into account issues of gender, race, culture, class, and sexual orientation. We have come to realize how strongly traditional approaches have been skewed in the direction of the dominant culture--white, male, heterosexist, and prioritizing the needs and experience of the middle and upper classes. We have attempted to modify our teaching, supervision, reading lists, and overall training approach to challenge trainees and ourselves to move toward broader, strength-based, and equity-based multicultural perspectives in our training. We describe our vision, how we incorporate it into our program structure, and a few of our training initiatives.
pANCA is a marker antibody associated with inflammatory bowel disease (IBD), including most patients with ulcerative colitis and a subset with Crohn's disease. This study addressed the hypothesis that pANCA reacts with an antigen(s) of microbial agents potentially relevant to IBD pathogenesis. Using a pANCA monoclonal antibody, we have previously identified the C-terminal basic random-coil domain of histone H1 as a pANCA autoantigen. BLAST analysis of the peptide databases revealed H1 epitope homologues in open reading frames of the Mycobacterium tuberculosis genome. Western analysis of extracts from six mycobacterial species directly demonstrated reactivity to a single, conserved approximately 32-kDa protein. Direct protein sequencing, followed by gene cloning, revealed a novel 214-amino-acid protein, an iron-regulated protein recently termed HupB. Sequence analysis demonstrated its homology with the mammalian histone H1 gene family, and recombinant protein expression confirmed its reactivity with the 5-3 pANCA monoclonal antibody. Binding activity of patient serum immunoglobulin G (IgG) to HupB did not correlate with reactivity to histone H1 or pANCA, indicating the complex character of the pANCA antigen. However, anti-HupB IgA was strongly associated with Crohn's disease (P < 0.001). These findings indicate that the 5-3 pANCA monoclonal antibody detects a structural domain recurrent among mycobacteria and cross-reactive with a DNA-binding domain of histone H1. The association of HupB-binding serum IgA with IBD provides new evidence for the association of a mycobacterial species with Crohn's disease.
Experiments have been performed to screen eight microbial commercial products that, according to the manufacturers, are able to degrade crude oil. This study compared the crude oil biodegradation activity of commercial inocula with that of natural inocula (activated sludge and tropical aquarium water). Some of the latter were previously adapted to the crude oil as the only carbon source. Nutrients and sorbents in the commercial formulations were eliminated, and each inoculum was precultured on marine yeast extract medium. Crude oil biodegradability tests were conducted with close initial substrate concentration to initial bacterial concentration ratios (S0/X0) of 0.94 g of crude oil/10(9) CFU, which allowed a comparison of biodegradation activity. The inocula oxidized the crude oil after a short lag time of less than 3-18 days. After that time, the rate of oxidation varied between 45 and 244 mg O2/(L.day). Crude oil biodegradation after a 28-day test was effective only for 10 out of 12 inocula (from 0.1 to 25% in weight). Biodegradation mainly corresponded to the saturated fraction of the crude oil; the asphaltene fraction was never significantly biodegraded. Our results led to the conclusion that natural inocula, either adapted or not adapted to crude oil, were the most active (from 16 to 25% of loss in crude oil weight) and only one commercial inoculum was able to degrade 18% of the crude oil. Other inocula had a biodegradation activity ranging from 0.1 to 14%.
