High on-treatment platelet reactivity (HOPR) is associated with increased risk of cardiovascular events in patients undergoing percutaneous coronary intervention (PCI). We randomised post-PCI patients with HOPR after 5 days of standard dual antiplatelet therapy (DAPT) to intensified therapy with aspirin 100 mg once daily in combination with either clopidogrel 150 mg once daily, clopidogrel 75 mg once daily plus cilostazol 100 mg twice daily, ticagrelor 90 mg twice daily, or standard therapy with clopidogrel 75 mg once daily (STD) for 1 month, after which all patients were switched to standard DAPT for a further 11 months. The primary outcome was residual HOPR rate at 1 month. We screened 1724 patients with light transmission aggregation studies and randomised 434 with HOPR. At 1 month the proportion of patients with persistent HOPR was significantly lower in the intensified therapy groups compared with STD group. Compared to the group receiving STD therapy, those receiving intensified therapy had significantly lower rate of major adverse cardiovascular events (MACE) at both 1 month and 12 months with no significant increase in bleeding. In patients with post-PCI HOPR, 1 month of intensified antiplatelet therapy provides greater platelet inhibition and improves outcomes without increasing bleeding.

Introduction COVID-19 was declared a pandemic by the World Health Organization on the 11th of March 2020 with the NHS deferring all non-urgent activity from the 15th of April 2020. The aim of our study was to assess the impact of COVID-19 on Trauma and Orthopaedic trainees nationally. Methods Trauma and Orthopaedic (T&O) specialty trainees nationally were asked to complete an electronic survey specifically on the impact of COVID-19 on their training. This UK based survey was conducted between May 2020 and July 2020. Results A total of 185 out of 975 (19%) T&O specialty trainees completed the survey. Redeployment was experienced by 25% of trainees. 84% of respondents had experienced a fall in total operating numbers in comparison with the same time period in 2019. 89% experienced a fall in elective operating and 63% experienced a fall in trauma operating. The pandemic has also had an effect on the delivery of teaching, with face to face teaching being replaced by webinar-based teaching. 63% of training programmes delivered regular weekly teaching, whilst 19% provided infrequent sessions and 11% provided no teaching. Conclusion This study has objectively demonstrated the significant impact of the COVID-19 pandemic on all aspects of T&O training.

Lateral epicondylitis, or ’tennis elbow’, is a common condition that usually affects patients between 35 and 55 years of age. It is generally self-limiting, but in some patients it may continue to cause persistent symptoms, which can be refractory to treatment. This review discusses the mechanism of disease, symptoms and signs, investigations, current management protocols and potential new treatments. Cite this article: Bone Joint J 2013;95-B:1158–64.

In our series of 710 consecutive laparoscopic total-extra-peritoneal hernia repairs over a period of 10 years (2001–2010), the authors report a rare case of delayed mesh infection developing 7 years postoperatively. A 56-year-old patient presented with diarrhoea and fullness in right iliac fossa region. Radiological imaging confirmed a floating mesh in a fluid-containing cavity. Subsequent exploration revealed a large preperitoneal cavity containing 550 ml of pus with a floating mesh in it. The mesh was removed and the patient was discharged after making a good recovery.

Management of rectal cancer has evolved over the years. In this condition preoperative investigations assist in deciding the optimal treatment. The relation of the tumor edge to the circumferential margin (CRM) is an important factor in deciding the need for neoadjuvant treatment and determines the prognosis. Those with threatened or involved margins are offered long course chemoradiation to enable R0 surgical resection. Endoanal ultrasound (EUS) is useful for tumor (T) staging; hence EUS is a useful imaging modality for early rectal cancer. Magnetic resonance imaging (MRI) is useful for assessing the mesorectum and the mesorectal fascia which has useful prognostic significance and for early identification of local recurrence. Computerized tomography (CT) of the chest, abdomen and pelvis is used to rule out distant metastasis. Identification of the malignant nodes using EUS, CT and MRI is based on the size, morphology and internal characteristics but has drawbacks. Most of the common imaging techniques are suboptimal for imaging following chemoradiation as they struggle to differentiate fibrotic changes and tumor. In this situation, EUS and MRI may provide complementary information to decide further treatment. Functional imaging using positron emission tomography (PET) is useful, particularly PET/CT fusion scans to identify areas of the functionally hot spots. In the current state, imaging has enabled the multidisciplinary team of surgeons, oncologists, radiologists and pathologists to decide on the patient centered management of rectal cancer. In future, functional imaging may play an active role in identifying patients with lymph node metastasis and those with residual and recurrent disease following neoadjuvant chemoradiotherapy.

A 52-year-old woman was admitted with neutropenic sepsis, 3 days following the final cycle of adjuvant chemotherapy for breast cancer. Her condition deteriorated with progressive abdominal distension, bilious vomiting and diarrhoea. Abdominal examination revealed a mild degree of peritonism. Five days later she passed a small bowel cast per rectum, showing gross fungal contamination on histology. She was managed conservatively with antibiotics and antifungal medications and nutritional support.

The role of laparoscopic ultrasound (LUS) during staging laparoscopy for pancreatic cancers is established but remains debatable in evaluating oesophagogastric cancers.A retrospective consecutive case series consisting of patients undergoing staging laparoscopy in two centres (centre A and B) was carried out over a 5-year period (2000-2005). Patients in centre B underwent LUS following laparoscopic assessment using a 7.5-MHz probe. Staging laparoscopy in both centres was performed using a standardised three-port protocol using a 30 degrees laparoscope. All suspicious lesions were sent for histological assessment for confirmation of malignancy.There were 201 patients in centre A (83 gastric, 138 lower oesophageal/junctional cancers) and 119 patients in centre B (51 and 68, respectively). There were no differences between the two centres for patient demographics and tumour site. There was no difference between the two centres for the detection of metastatic disease using laparoscopic assessment alone (A 13% versus B 20%, p = 0.12). However, there was a significant difference (13% versus 28%, p = 0.001) with the additional use of LUS in centre B. The findings in the additional 8% (n = 9) were para-aortic lymphadenopathy (n = 5), liver metastasis (n = 3) and local extension (n = 1). Five had gastric and four lower oesophageal/junctional cancers. The negative predictive value was 6.4% for centre A and 4.5% for centre B.The addition of LUS increased the detection rate of metastasis by 8% but there was little impact on the false-negative rate. LUS is useful in detecting metastatic lymphadenopathy beyond the limits of curative resection and liver metastasis.

AIM To describe a CT technique for guiding diagnostic and therapeutic injections in the hind- and mid-foot. MATERIALS AND METHODS Over a period of 50 months, 28 individuals were referred for diagnostic and therapeutic hind- and mid-foot injections before possible arthrodesis. A CT technique was developed that allowed entry into the various joints using a vertical approach. Numbers of joints injected were as follows: posterior subtalar, 21; talonavicular, 4; calcaneonavicular, calcaneocuboid, navicular-cuneiform and 5th metatarsocuboid joints, 1 each. RESULTS All injections but one were technically successful. Significant relief of symptoms was noted by 16 participants, whereas for 9 there was no improvement and for 3 a partial response was achieved. CONCLUSION CT is a simple and safe alternative to fluoroscopy for guiding diagnostic and therapeutic foot injections, and may be the technique of choice in cases of disordered anatomy.

Mucosa-associated lymphoid tissue (MALT) is a type of extra nodal malignant lymphoma seen in organs such as the stomach, thyroid and salivary glands. Furthermore, occurrence of colorectal MALT lymphoma is extremely rare. We report a case of a solitary rectal MALT lymphoma treated by surgical resection and radiotherapy. Lymphoma should be considered as a rare differential diagnosis when dealing with large bowel pathology. We would advocate the use of surgery as a primary treatment option for a medically fit patient.

Appendicitis in a remaining duplicate appendix is a rare phenomenon and we report such a case. The unusual presentation of this anomaly can cause diagnostic dilemmas. Awareness of this condition is important because failure to recognise the condition may lead to errors in diagnosis and subsequent management. A young woman was admitted with a 3 day history of sudden onset, severe, central abdominal pain radiating towards the right iliac fossa, anorexia, rigors and vomiting. Her only significant past history was open appendectomy 4 years previously for a gangrenous appendix. The patient was pyrexial on admission but haemodynamically …

Introduction and aim of study: there is recent evidence that the immune system plays an essential role in the pathogenesis of atherosclerosis, with both cellular and humoral mechanisms being involved. Heat-shock proteins (HSPs) have been detected in atherosclerotic lesions, and antibodies to HSPs have also been found to be raised in patients with carotid stenoses. The aim of our study was to examine the level of anti-HSP70 antibodies in patients with other vascular diseases. Materials and methods: a questionnaire was designed for the subjects in the study, with documentation of clinical details and ankle–brachial pressure index. Patients with concomitant infection, malignancy, hepatorenal failure, or recent surgery were excluded. Enzyme-linked immunosorbent assay (ELISA) was used to identify anti-HSP70 antibodies in the sera in different dilutions. Graphs of optical density (OD) vs. negative log dilution were plotted, the gradient of which was taken to be the estimated optical density for each subject (proportional to antibody level). Our groups consisted of controls (n =21, mean age 59.0±19.2), lower limb claudicants ( n =19, mean age 60.0±12.6), patients with lower-limb critical ischaemia ( n =22, mean age 68.5±10.07), and patients with abdominal aortic aneurysms ( n =20, mean age 69.9±6.2). Results: we found no correlation between age and the estimated OD in our subjects (Spearman's correlation coefficient ( r )=0.123, one-tailed p value was 0.135). Patients with intermittent claudication, critical lower limb ischaemia, and aneurysms had higher estimated OD, and therefore higher anti-HSP70 antibody levels, than controls (Mann–Whitney test p =0.0127, 0.0037, 0.0008, respectively). Conclusions: our data provide the first evidence of a correlation between anti-HSP70 antibodies and different types of vascular diseases, suggesting that HSP70 might be involved in the pathogenesis and propagation of atherosclerosis. Since the immune response to HSPs can be modulated, this opens up the possibility of new therapeutic approaches.
