Abstract:

Key content: Antenatal imaging is a screening tool integral to ensuring women are cared for in the most appropriate setting. The pretest probability of PAS should be considered before any imaging is performed. PAS is an iatrogenic disease. Any process which disrupts the endometrium increases the risk. Caesarean birth is the most common cause. Specialist placental assessment in asymptomatic women should be offered between 24 and 28 weeks. Ultrasound and MRI have similar diagnostic value, and MRI should only be used as an adjunct following ultrasound assessment by a specialist in placental imaging. Learning objectives: To understand the pathophysiology of PAS. To understand the distinction between screening for and diagnosis of PAS. To increase confidence in the interpretation of sonographic features of PAS. To provide a rationale for PAS care being provided in centres of excellence. Ethical issues: If women increasingly prefer caesarean section over vaginal birth, it is likely that this trend will result in increasing numbers of complex caesarean deliveries and PAS cases. Many studies have shown decreased morbidity and mortality if PAS cases are managed by an experienced multi-disciplinary team (MDT) in a PAS centre of excellence; therefore, accurate screening and timely referral are vital to improve patient care for women with risk factors.

Abstract:

Despite the implementation of latex-free gloves, the issue of natural rubber latex hypersensitivity persists within medical practice, posing challenges for both patients and health care professionals. A comprehensive understanding of the demographic groups susceptible to this condition is essential, along with the establishment of robust perioperative assessment and management protocols aimed at minimising complications and enhancing safety. This article endeavours to delve into the intricacies of perioperative management concerning latex hypersensitivity among patients, while also elucidating its ramifications for health care practitioners.

Abstract:

In 2008 the Postgraduate Medical Education and Training Board (PMETB) Review of Oral and Maxillofacial Surgery (OMFS) recommended that OMFS specialty training should start with second-degree studies. This recommendation has not yet happened. Currently, no OMFS controlled places at medical/dental schools are directly linked to OMFS Specialty Training (ST) posts. 'OMFS controlled' in this paper refers to dedicated places on shortened second degree courses to which OMFS specialists/trainers have the key role in selection. Freedom of Information requests were sent to 14 medical schools known to have OMFS 'controlled' second-degree MB places: Aberdeen, Birmingham, Bristol, Cambridge, Cardiff, Glasgow, Leeds, Liverpool, Manchester, London-Kings, London-QMUL, Newcastle, Plymouth and York/Hull. Information was also requested from the London-Kings BDS Dental Programme for Medical Graduates (DPMG). These data were supplemented by information from consultants and trainees with experience of the processes. Replies were received from six medical schools in Birmingham, Cambridge, Glasgow, Liverpool, London-Kings, and London-QMUL, plus the dental school of London – Kings DPMG. These seven programmes provide approximately 30 OMFS controlled places per year. The application ratios, between 5:1 and 29:1, are significantly more competitive than selection to ST1 and ST3 places. There are more OMFS controlled second degree places than presented in this paper which only details universities from whom replies were received. If all students in OMFS controlled second-degree places progressed to ST without loss, there are more than sufficient to fill all available OMFS ST places. Linking OMFS controlled second degree places through to OMFS ST posts would deliver the key PMETB recommendation in a process which would be more competitive than current ST selection. For OMFS trainees whose first degree was medicine, OMFS selected places at shortened dental courses are needed outside London.

Abstract:

INTRODUCTION: Direct laryngoscopy and biopsy is the gold standard for obtaining a tissue diagnosis in patients with suspected laryngeal cancer. In patients with advanced disease or other medical comorbidities, this may come with significant anaesthetic risks, including tracheostomy. Ultrasonography-guided biopsy has been widely used in the diagnosis of malignancy involving cervical lymph nodes but it is not commonly employed in the diagnosis of laryngeal tumours. A systematic review was undertaken to assess the literature looking at whether ultrasonography-guided transcutaneous fine needle aspiration cytology (FNAC) is an adequate method in diagnosing laryngeal malignancy.

METHODS: Two independent researchers conducted a systematic review of the literature using the MEDLINE and Cochrane Library databases in accordance with the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines.

RESULTS: A total of 568 studies were identified from the search, of which 3 met the inclusion criteria, resulting in 162 patient episodes. The pooled accuracy of transcutaneous FNAC in acquiring a sample adequate for histological diagnosis was 74.9%. Data on complications were limited, with a few cases of mild haemoptysis being recorded.

CONCLUSIONS: Transcutaneous FNAC can be considered a safe and quick method for establishing a histological diagnosis of laryngeal lesions, particularly in patients who may be severely comorbid, and it could therefore could reduce the risks of general anaesthesia and tracheostomy prior to commencing definitive treatment.

Abstract:

PURPOSE: Men with high-risk prostate cancer (PCa) are treated with androgen deprivation therapy (ADT) and radiotherapy, but the disease reoccurs in 30% of patients. Biochemical recurrence of PCa after treatment is influenced by tumour hypoxia. Tumours with high levels of hypoxia are aggressive, resistant to treatment, and have increased metastatic capacity. Gene expression signatures derived from diagnostic biopsies can predict tumour hypoxia and radiosensitivity, but none are in routine clinical use, due to concerns about the applicability of these biomarkers to new patient cohorts. There has been no or limited testing in cohorts of high-risk PCa. METHODS AND MATERIALS: We generated transcriptomic data for cohorts of high-risk PCa patients. Patients were treated with ADT followed by external beam radiotherapy with or without a brachytherapy boost. Biomarkers curated from the literature were calculated from pre-treatment biopsy gene expression data. The primary endpoint for survival analyses was biochemical recurrence-free survival (bRFS) and the secondary endpoints were distant metastasis-free survival (DMFS) and overall survival. RESULTS: The performance of the selected biomarkers was poor, with none achieving prognostic significance for bRFS or DMFS in any cohort. The brachytherapy boost cohort received shorter durations of ADT than the conventionally fractionated or hypofractionated cohorts (Wilcoxon rank sum test, p=2.1×10-18 and 2.3×10-10 respectively) and had increased risk of distant metastasis (log-rank test, p=8×10-4). There were no consistent relationships between biomarker score and outcome for any of the endpoints. CONCLUSIONS: Hypoxia and radiosensitivity biomarkers were not prognostic in high-risk PCa patients treated with ADT plus radiotherapy. We speculate that the lack of prognostic capability could be caused by the variable hypoxia-modifying effects of the ADT that these high-risk patients received before and during definitive treatment with radiotherapy. A deeper understanding of biomarker construction, performance and inter-cohort transferability in relation to patient characteristics, sample handling and treatment modalities is required before hypoxia biomarkers can be recommended for routine clinical use in the pre-treatment setting.

Abstract:

BACKGROUND: While surgery plays a pivotal role in the management of ileal Crohn's disease, the risk of endoscopic recurrence following an ileocaecal resection can be greater than 65% within 12 months of surgery. More than 90% of patients with Crohn's disease have a concomitant diagnosis of bile acid diarrhea following an ileal resection. This pilot study aimed to assess whether the use of bile acid sequestrants in patients with Crohn's disease who have undergone a primary terminal ileal resection with concomitant bile acid diarrhea can alter the microbiome and prevent disease recurrence. METHODS: Patients with Crohn's disease who underwent a primary terminal ileal resection and had symptoms of diarrhea within 1-3 months of surgery underwent 75SeHCAT testing for bile acid diarrhea. If positive (75SeHCAT <= 15%), patients were treated with colesevelam and stool samples were collected at 4 weeks, 8 weeks, and 6-12 months posttreatment. If negative (75SeHCAT > 15%), treatment was not given and were reviewed in the clinic as per local guidelines. All patients underwent a 6-12 month postoperative colonoscopy where further stool samples and mucosal biopsies were taken. Disease activity was established using the endoscopic Rutgeert's score, with disease remission defined as Rutgeert's score <i2 and disease recurrence >=i2. 16S ribosomal RNA gene analysis was undertaken for the collected fecal and mucosal samples to assess alpha/beta-diversity and microbial composition. RESULTS: A total of 14 patients who completed the study, 10 of whom had a   75SeHCAT positive diagnosis of bile acid diarrhea and were started on   treatment with colesevelam. Four patients did not require treatment as 3 were asymptomatic and 1 had a negative 75SeHCAT scan. Three of the fourteen patients had disease recurrence at their 6-12 month postoperative colonoscopy assessment, of which 1 patient was taking colesevelam and 2 patients were not taking colesevelam. A total of 44 fecal samples and 44 mucosal biopsies underwent 16S ribosomal RNA gene analysis to assess alpha/beta-diversity and microbial composition. In the colesevelam treated patients there was no significant difference in alpha/beta-diversity pre- and posttreatment. Pretreatment, the 3 most abundant bacterial classes in all patients were Bacteroidia, Clostridia, and Gammaproteobacteria. Following 6-12 months of treatment, out of the 9 patients on colesevelam, 5/9 (55.6%) had a reduction in Bacteroidia, 9/9 (100%) had an increase in Clostridia, and 7/9 (77.8%) had a reduction in Gammaproteobacteria. Of the 2 patients not given colesevelam, one showed a reduction in Bacteroidia, increase in Clostridia and a reduction in Gammaproteobacteria. CONCLUSIONS: This small pilot study demonstrated that patients who were given colesevelam, were more likely to be in disease remission at their 6-12 months colonoscopy review compared with those not treated. Furthermore, treatment with colesevelam may have a role in altering the microbiome to help maintain remission states in postoperative Crohn's disease. Larger mechanistic studies are now needed to confirm these findings and demonstrate statistical significance as well as investigate whether this benefit may be present even in those patients with 75SeHCAT negative disease.

Abstract:
INTRODUCTION: The aim of this study was to investigate the safety of day-case laparoscopic cholecystectomy, and the association between day-case rates and, post the COVID-19 pandemic, recovery of activity to prepandemic levels for integrated care boards (ICBs) in England. METHODS: This was a retrospective observational study of the Hospital Episodes Statistics (HES) data set. Elective laparoscopic
cholecystectomies for the period 1 January 2019 to 31 December 2022 were identified. Activity levels for 2022 were compared with those for the whole of 2019 (baseline). Day-case activity was identified where the length of stay recorded in the HES was zero days. RESULTS: Data were available for 184,252 patients across the 42 ICBs in England, of which 120,408 (65.3%) were day-case procedures. By December
2022, activity levels for the whole of England had returned to 88.2% of prepandemic levels. The South West region stood out as having recovered activity levels to the greatest extent, with activity at 97.3% of
prepandemic levels during 2022. The South West also had the highest postpandemic day-case rate at 74.9% of all patients seen as a day-case during 2022; this compares with an England average of 65.3%. At an ICB level, there was a significant correlation between day-case rates and postpandemic activity levels (r = 0.362, p = 0.019). There was no strong or consistent evidence that day-case surgery had poorer patient outcomes than inpatient surgery. CONCLUSIONS: Recovery of elective laparoscopic cholecystectomy activity has been better in South West England than in other regions. Increasing day-case rates may be important if ICBs in other regions are to increase activity levels up to and beyond prepandemic levels.
