Prevalence of active Charcot disease in the East Midlands of England.

AIMS: To undertake a prospective point prevalence study of the prevalence of active Charcot neuro-inflammatory osteoarthropathy (Charcot disease) in a circumscribed part of England and to audit the time elapsing between disease onset and first diagnosis. METHODS: The prevalence of active Charcot disease of the foot during a single month was assessed by specialist foot care teams at seven secondary care services in the East Midlands region of England. RESULTS: A total of 90 cases were identified, representing 4.3 per 10 000 of the 205 033 total diabetes population of the region. The time elapsed from first presentation to any healthcare professional until diagnosis was also assessed. While the diagnosis was suspected or confirmed in one-third of patients within 2 weeks, it was not made for 2 months or more in 23 patients (24%). CONCLUSIONS: Non-specialist professionals should have greater awareness of the existence of this uncommon complication of diabetes in the hope that earlier diagnosis will lead to lesser degrees of deformity.

Female gender and diabetes mellitus increase the risk of recurrence after laparoscopic incisional hernia repair.

BACKGROUND: Laparoscopic hernia repair is used widely for the repair of incisional hernias. Few case studies have focussed on purely 'incisional' hernias. This multicentre series represents a collaborative effort and employed statistical analyses to provide insight into the factors predisposing to recurrence of incisional hernia after laparoscopic repair. A specific hypothesis (ie, laterality of hernias as well as proximity to the xyphoid process and pubic symphysis predisposes to recurrence) was also tested. METHODS: This was a retrospective study of all laparoscopic incisional hernias undertaken in six centres from 1 January 2004 to 31 December 2010. It comprised a comprehensive review of case notes and a follow-up using a structured telephone questionnaire. Patient demographics, previous medical/surgical history, surgical procedure, postoperative recovery, and perceived effect on quality of life were recorded. Repairs undertaken for primary ventral hernias were excluded. A logistic regression analysis was then fitted with recurrence as the primary outcome. RESULTS: A total of 186 cases (91 females) were identified. Median follow-up was 42 months. Telephone interviews were answered by 115/186 (62%) of subjects. Logistic regression analyses suggested that only female sex (odds ratio (OR) 3.53; 95% confidence interval (CI) 1.39-8.97) and diabetes mellitus (3.54; 1-12.56) significantly increased the risk of recurrence. Position of the defect had no statistical effect. CONCLUSIONS: These data suggest an increased risk of recurrence after laparoscopic incisional hernia repair in females and subjects with diabetes mellitus. These data will help inform surgeons and patients when considering laparoscopic management of incisional hernias. We recommend a centrally hosted, prospectively maintained national/international database to carry out additional research.

Pain after laparoscopic antireflux surgery.

INTRODUCTION: The benefits of antireflux surgery are well established. Laparoscopic techniques have been shown to be generally safe and effective. The aim of this paper was to review the subject of pain following laparoscopic antireflux surgery. METHODS: A systematic review of the literature was conducted using the PubMed database to identify all studies reporting pain after laparoscopic antireflux surgery. Publications were included for the main analysis if they contained at least 30 patients. Operations in children, Collis gastroplasty procedures, endoluminal fundoplication and surgery for paraoesophageal hernias were excluded. The frequency of postoperative pain was calculated and the causes/management were reviewed. An algorithm for the investigation of patients with pain following laparoscopic fundoplication was constructed. RESULTS: A total of 17 studies were included in the main analysis. Abdominal pain and chest pain following laparoscopic fundoplication were reported in 24.0% and 19.5% of patients respectively. Pain was mild or moderate in the majority and severe in 4%. Frequency of pain was not associated with operation type. The authors include their experience in managing patients with persistent, severe epigastric pain following laparoscopic anterior fundoplication. CONCLUSIONS: Pain following laparoscopic antireflux surgery occurs in over 20% of patients. Some have an obvious complication or a diagnosis made through routine investigation. Most have mild to moderate pain with minimal effect on quality of life. In a smaller proportion of patients, pain is severe, persistent and can be disabling. In this group, diagnosis is more difficult but systematic investigation can be rewarding, and can enable appropriate and successful treatment.

Long term follow-up and risk of breast cancer after a radial scar or complex sclerosing lesion has been identified in a benign open breast biopsy.

AIMS: Radial scars (RS)/complex sclerosing lesions (CSL) are rare, benign breast lesions of unknown aetiology. Associations with breast cancer have been suggested particularly with larger lesions. This study aims to identify the risk of developing subsequent breast cancer after excision of a benign RS/CSL with respect to lesion size and compared to expected rates in the normal UK population. METHODS: A prospective cohort analysis was performed on patients diagnosed with RS/CSL in benign, open breast biopsy specimens over a 20-year period. The rate of subsequent breast cancer development was compared to expected rates in the normal UK population. Subjects were divided into two groups according to lesion size and the rates of subsequent breast cancer compared. RESULTS: 149 women without proliferative breast disease were followed for an average of 68 months. Five women developed subsequent cancer, equating to a rate of 0.84% per year. This compares to 0.32% per year in the normal population (RR 2.6, 95% CI 0.86-6.0). There were two subsequent cancers in the RS group and three subsequent cancers in the CSL group, P = 0.64. CONCLUSIONS: The study finds no evidence to suggest that lesions greater than 10 mm (CSL) have any greater risk of developing cancer after excision than those below 10 mm (RS). Women treated for RS/CSL do not need any additional follow-up beyond routine mammographic breast screening. Additional surveillance should only be performed if there is associated pathology indicating an increased risk of subsequent malignancy.

The surgical management of acute upper gastrointestinal bleeding: a 12-year experience.

INTRODUCTION: Acute upper gastrointestinal bleeding (AUGIB) is a common reason for admission to gastroenterologists, with only 2% of patients requiring surgical intervention. The aim of this study was to review the surgical management of patients with non-variceal AUGIB in a single institution over a 12-year period and compare practice with recognised regional and national standards. MATERIALS AND METHODS: Data was collected retrospectively for all patients undergoing surgery for AUGIB between September 1995 and September 2007. Audit standards included the local hospital protocol, British Society of Gastroenterology Endoscopy Committee guidelines and the UK Comparative Audit of AUGIB and the Use of Blood. RESULTS: 53 patients were identified, of which 41 case notes were available. Mean (range) age of the patients was 75.8 (45-92) years. 56% had pre-existing cardiorespiratory comorbidity and 63% were taking anti-inflammatory drugs. Pre-operative Rockall score was >or=7 in 46% and ASA score was >or=3 in 65% of patients. 56% of operations were performed by the registrar, compared with 20% reported nationally. All cases after 2004 were performed by the consultant. No operations were performed after midnight beyond 1999. 23 (56%) patients suffered post-operative complications compared with 55% reported nationally; cardiorespiratory (n = 16), wound infection (n = 7) and rebleed (n = 6). 37% required intensive care support and median length of hospital stay was 13 days. In-hospital mortality rate was 10%, compared with 30% reported nationally and this increased with rising Rockall, Blatchford, APACHE-2, P-POSSUM and Charlson scores. CONCLUSIONS: These findings highlight the high rate of morbidity and mortality associated with surgical treatment for AUGIB. The small volume of cases and reduction in registrar operating raises training issues. An integrated approach with greater use of interventional radiology is likely to play a greater role in the future.

Unusual diagnoses presenting as incarcerated inguinal hernia: a case report and review of the literature.

Many different pathological processes can present as an incarcerated inguinal hernia. We present an unusual case of sigmoid diverticular abscess presenting as a left incarcerated inguinal hernia and review the literature on this subject. This was treated with open drainage of the abscess cavity and laparotomy with segmental sigmoid resection and primary anastomosis.

Purified fusion protein vaccine protects against lower respiratory tract illness during respiratory syncytial virus season in children with cystic fibrosis.

OBJECTIVE: To test in a double blind, placebo-controlled study a purified fusion protein (PFP-2) vaccine against respiratory syncytial virus (RSV) in RSV-seropositive children with cystic fibrosis (CF). METHODS: Seventeen CF children, mean age 4.5 years, received PFP-2 vaccine and 17 CF children, mean age 5.8 years, received a saline vaccine. At enrollment the Shwachman clinical score, Brasfield radiographic score, oxygen saturation (SpO2), anthropometric indices and other variables were recorded. After vaccination the reactions were assessed daily for 7 days. During the RSV season weekly telephone interviews were performed and children with an acute respiratory illness were evaluated and cultured for RSV. Serum was drawn before vaccination, 1 month after vaccination and at the end of the RSV season and tested for antibodies to RSV. RESULTS: Other than age the baseline measurements at enrollment were similar between groups. The PFP-2 vaccine produced mild local reactions and induced a significant neutralizing antibody response in two-thirds of the vaccinees and a significant enzyme-linked immunosorbent assay-fusion glycoprotein antibody response in nearly all the PFP-2 vaccinees. Vaccine-enhanced disease was not observed in PFP-2 vaccines infected with RSV. Protection against RSV infection was not observed; however, a significant reduction (t test, P < 0.01) in mean number of lower respiratory tract illnesses (0.8 vs. 2.1), antibiotic courses (2.2 vs 4.5) and days ill (30.5 vs. 67) occurred among RSV-infected PFP-2 vaccinees. CONCLUSIONS: Efficacy of the PFP-2 vaccine against lower respiratory tract illness during the RSV season was shown in RSV-seropositive children with CF.

Stress protein synthesis by crayfish CNS tissue in vitro.

Some crustacean axons remain functional for months after injury. This unusual property may require stress proteins synthesized by those neurons or provided to them by glial cells. To begin to explore this hypothesis, we examined the conditions that stimulated stress protein synthesis by crayfish CNS tissue in vitro. Incubation for 1-15 h with arsenite or at temperatures about 15 degrees C higher than the acclimation temperature of 20 degrees C induced transient expression of several stress proteins. The heat stress response was blocked by Actinomycin D, suggesting that synthesis of new mRNA was required. In addition, the major crayfish 66 kD stress protein and its mRNA had sequence identities with the 70 kD stress proteins of mammals. Since the crayfish stress response has much in common with that of other organisms, the unique advantages of the crayfish nervous system can be used to study the impact of stress proteins on glial and neuronal function.
