Use of the Internet by Patients Undergoing Elective Hernia Repair or Cholecystectomy

INTRODUCTION

Patient-directed information available on the internet is not always regulated; it may be confusing and sometimes just overwhelming. We aimed to establish the proportion of patients undergoing two common surgical procedures, who searched the internet for information about their operations and to assess the usefulness of the information they received.

PATIENTS AND METHODS

A total of 105 consecutive patients undergoing elective abdominal wall hernia repair (n = 54) or laparoscopic cholecystectomy (n = 51) in a single surgical firm were included in the study. Patients were counselled about their operation in pre-operative assessment clinics and standard trust information leaflets were provided without any mention of this study. Patients were then asked to complete a questionnaire on the morning of their operation.

RESULTS

All patients completed the questionnaire. Of the patients, 59% stated that they had access to the internet and 77% of these accessed the internet over 2 h a week. Of the patients with internet access, 31% used it to acquire additional information about their operations and 58% used internet search engines. Of the patients who searched the internet regarding their operations, 26% were confused and/or worried by the information they received.

CONCLUSIONS

A significant proportion of patients undergoing common surgical procedures used the internet and about one-third of them specifically sought information about their operation on the internet. Such information can cause worry and confusion in patients. Our study highlights the need for regulated, comprehensible, patient information on hospital websites to which patients should be directed.     

Acoustic monitoring (RFM) of total hip arthroplasty results of a cadaver study

Introduction

At present there are no reliable non-traumatic and non-invasive methods to analyse the healing process and loosening status after total hip replacement. Therefore early as well as late loosening of prosthesis and interface component problems are difficult to be found or diagnosed at any time.

Methods

In a cadaver study the potential application of Resonance Frequency Monitoring (RFM) will be evaluated as a non-invasive and non-traumatic method to monitor loosening and interface problems in hip replacement. In a 65 year old female cadaver different stability scenarios for a total hip replacement (shaft, head/modular head and cup, ESKA, Luebeck, Germany) are simulated in cemented and cement less prosthesis and then analysed with RFM. The types of stability vary from secure/press-fit to interface-shaft disruption.

Results

The RFM shows in cemented as well as cement less prosthesis significant intra-individual differences in the spectral measurements with a high dynamic (20 dB difference corresponding to the factor 100 (10000%)), regarding the simulated status of stability in the prosthesis system.

Conclusion

The results of the study demonstrate RFM as a highly sensitive non-invasive and non-traumatic method to support the application of RFM as a hip prosthesis monitoring procedure. The data obtained shows the possibility to use RFM for osteointegration surveillance and early detection of interface problems, but will require further evaluation in clinical and experimental studies.     

Care related pain in hospitalized patients: A cross‐sectional study

Context: Care‐related pain includes pain occurring during transportation, movement, diagnostic imaging, physical examination, or treatment. Its prevalence has never been assessed in a large adult inpatient population. Objective: To identify the procedures likely to induce or increase pain in hospital patients, attempting to separate the most painful from those reported as most frequently inducing pain. Design: A single‐day cross‐sectional survey conducted in two large French teaching hospitals, including all hospitalized patients, free of communication problems. One third was randomly selected and interviewed about the painful episodes that had occurred or were associated with the procedures performed during the previous two weeks. Patients were interviewed using a structured questionnaire. Results: Six‐hundred‐eighty‐four patients were randomly selected. Six‐hundred‐seventy‐one painful events were reported in 55% of the patients, with an average of 1.8events/patient. Fifty‐two percent of the painful events were associated with procedures performed by non‐medical staff; 38% of the painful episodes occurred during procedures involving vascular puncture and 24% during patients’ mobilization. In 57% of painful procedures, pain was rated as severe or extremely severe. The most painful procedures were invasive procedures, other than vascular and non vascular punctures (74% of severe and extremely severe painful episodes). Maximum pain intensity was rated higher for procedures that were repeated than for those experienced only once (62% versus 53%, p=0.02). Conclusion: This survey gives new insight into our daily practice. Proper management of care‐related pain should be a major concern of all hospital staff to improve the quality of our health care.     

Clinical applications of molecular monitoring in leukemia

Molecular analyses of the leukemias have been able to identify unique markers that can be used as "molecular signatures" for the various diseases. In acute promyelocytic leukemia, qualitative polymerase chain reaction (PCR) has helped define the clinical syndrome and has been used to guide therapy. Quantitative modifications of the PCR technique have been investigated in chronic myelogenous leukemia and acute lymphocytic leukemia and found to correlate with clinical outcomes. These assays may soon be incorporated into standard clinical management and may result in a new definition of response.     

Anti-GBM nephritis in the mouse: severe proteinuria in the heterologous phase

Summary Highly reproducible anti glomerular basement membrane (GBM) nephritis has been induced in the mouse after a single injection of rabbit or goat antibody against purified homologous GBM. The severity of albuminuria was closely related to the amount of antibody given. With doses of 4 mg or more, low serum albumin concentrations, sometimes accompanied by ascites and oedema, were observed after 1 week. Glomerular injury was characterized by an initial accumulation of polymorphonuclear granulocytes followed by thrombosis and necrosis, the extent of which defined the outcome of the glomerulonephritis. With high doses of antibody the exudative lesions entered a chronic phase, while at doses lower than 2 mg remission of the lesions occurred. Immunofluorescence studies showed prompt linear fixation of the injected anti-bodies to the glomerular capillary wall, accompanied by immediate binding of C3 in a fine granular pattern. Fibrin deposits appeared at 2 h in some glomeruli, increased thereafter, and were present after one day in more than 90% of the glomeruli in mice that had received 4 mg of antibody. This new reproducible model in the mouse is suited for the study of the relationship between activation of mediator systems, histological lesions, and proteinuria.     

Serological status: a predictor of response to intensive therapy in rheumatoid arthritis

BackgroundRheumatoid arthritis is the most common chronic inflammatory disease in the UK. Serological status such as rheumatoid factor (RF) and anti-citrullinated peptide antibody (ACPA) positivity predict poor outcomes. Early intensive treatment regimens targeting remission reduce disease activity, structural damage, and long-term disability. However, we do not know whether all patients with active disease should have such intensive treatment regimens. Can serological status be used to predict the need for intensive therapy?MethodsWe analysed samples from a published randomised controlled trial which compared four treatment regimens in patients with early active rheumatoid arthritis (disease duration <2 years): methotrexate monotherapy, double therapy (methotrexate plus either ciclosporin or prednisolone), and triple therapy (methotrexate plus ciclosporin plus prednisolone). The trial randomised 467 patients (68% female, median age 54 years [IQR 46–63]). Disease activity was assessed with the disease activity score of 28 joints (DAS28). Remission was defined as DAS28 less than 2·6 at 24 months. RF isotypes (IgM and IgA) and ACPA levels were measured with commercial ELISA kits. Statistical analysis used Pearson's chi-squared test.Findings402 (86%) patients were positive for IgM RF, 346 (74%) for IgA RF, and 346 (74%) for ACPA. 98 (21%) patients achieved remission at 24 months. In RF IgM negative cases (n=65) the proportion of patients achieving remission at 24 months was similar in all treatment groups (25%, 22%, and 30% for monotherapy, double therapy, and triple therapy, respectively). In RF IgM positive cases, significantly fewer patients achieved remission with monotherapy (13/65, 17%) and double therapy (24/157, 15%) than with triple therapy (27/80, 34%) (p=0·001). There were similar, consistent findings with IgA RF and ACPA, with significantly more seropositive patients achieving remission with triple therapy than with monotherapy.InterpretationContemporary treatment of rheumatoid arthritis emphasises the use of intensive therapy to achieve remission. However, we have shown that not all patients require such an aggressive approach to therapy. Given the heterogeneity of the diease, treatment should be personalised to the individual, which would minimise costs of treatment as well as potentially toxic side-effects. Our study shows that only seropositive patients with rheumatoid arthritis should be given more intensive therapies.FundingNational Institute for Health Research.     

Bone marrow transplantation for patients with Philadelphia chromosome- positive acute lymphoblastic leukemia

We report the treatment outcome of allogeneic bone marrow transplantation in ten patients with Philadelphia chromosome-positive acute lymphoblastic leukemia. Six patients are alive and well for 6 to 30 months (median 19 months) after transplantation. Four patients died with transplant related complications. In view of the poor prognosis associated with this disease, marrow ablation followed by allogeneic or syngeneic marrow grafting may be the preferred treatment modality if a suitable marrow donor is available.     

Comparison of clinical and self-reported diagnoses for participants on a community-based arthritis self-management programme

OBJECTIVE: With the advent of community-based arthritis education programmes, it is important to determine the accuracy of participants' self-reported diagnoses. The purpose of this study was to determine the level of agreement between general practitioner (GP)-recorded and self- reported diagnoses of participants attending an Arthritis Self- Management Programme (ASMP). METHODS: Participants enrolling on the ASMP were asked to (a) identify their type of arthritis via a self- administered postal questionnaire and (b) obtain a written confirmation of their diagnosis from their GP. The sample (n = 613) comprised mainly women (83%) with a mean age of 58.8 yr (S.D. 12.6) and a mean disease duration of 15.4 yr (S.D. 12.5). RESULTS: Participants' self-reported diagnoses were confirmed by GPs in 534 cases [87.1%, 95% confidence interval (CI): 84.4 89.8%]. Confirmed diagnoses were reported by 86.9% (95% CI: 83.1-90.7%) of those with osteoarthritis (OA) and 96.1% (95% CI: 93.6 98.6%) of those with rheumatoid arthritis (RA). The concordance rate for all other types of arthritis combined was lower at 60.5% (95% CI: 49.5-71.5%). There were no significant differences with respect to age, gender, education, physical functioning, duration of disease and number of GP visits between those who correctly identified their type of arthritis and those who did not. CONCLUSIONS: This study suggests that the majority of RA and OA participants attending an arthritis education programme can correctly identify their specific type of arthritis.
