RESUMO
BACKGROUND: Perianal abscess is common. Traditionally, postoperative perianal abscess cavities are managed with internal wound packing, a practice not supported by evidence. The aim of this randomized clinical trial (RCT) was to assess if non-packing is less painful and if it is associated with adverse outcomes. METHODS: The Postoperative Packing of Perianal Abscess Cavities (PPAC2) trial was a multicentre, RCT (two-group parallel design) of adult participants admitted to an NHS hospital for incision and drainage of a primary perianal abscess. Participants were randomized 1:1 (via an online system) to receive continued postoperative wound packing or non-packing. Blinded data were collected via symptom diaries, telephone, and clinics over 6 months. The objective was to determine whether non-packing of perianal abscess cavities is less painful than packing, without an increase in perianal fistula or abscess recurrence. The primary outcome was pain (mean maximum pain score on a 100-point visual analogue scale). RESULTS: Between February 2018 and March 2020, 433 participants (mean age 42 years) were randomized across 50 sites. Two hundred and thirteen participants allocated to packing reported higher pain scores than 220 allocated to non-packing (38.2 versus 28.2, mean difference 9.9; P < 0.0001). The occurrence of fistula-in-ano was low in both groups: 32/213 (15 per cent) in the packing group and 24/220 (11 per cent) in the non-packing group (OR 0.69, 95 per cent c.i. 0.39 to 1.22; P = 0.20). The proportion of patients with abscess recurrence was also low: 13/223 (6 per cent) in the non-packing group and 7/213 (3 per cent) in the packing group (OR 1.85, 95 per cent c.i. 0.72 to 4.73; P = 0.20). CONCLUSION: Avoiding abscess cavity packing is less painful without a negative morbidity risk. REGISTRATION NUMBER: ISRCTN93273484 (https://www.isrctn.com/ISRCTN93273484).

Perianal abscess is a common, painful condition due to infection and swelling around the anus caused by blockage of the anal glands. The treatment of perianal abscess has stayed the same for over 50 years. An operation is performed under general anaesthetic to cut the skin and drain the infection. This is followed by continued internal dressing (packing) of the remaining cavity (hole) until the skin has healed over. Packing changes are needed multiple times a week for several weeks. Packing is the accepted treatment as it is believed to reduce the chance of the abscess coming back, and also reduces the chance of perianal fistula forming. There are no medical studies to support this idea. Perianal fistula (an abnormal passage between the skin around the anus, and the inside of the anal canal or rectum) is a long-term condition, which causes pain, and pus (and sometimes faeces) discharge, and often needs another operation (or multiple operations) to fix it. This trial was performed to demonstrate if no packing of a perianal abscess would result in a reduction of pain, with no increase in unwanted abscess recurrences and fistulas, in comparison to the standard treatment of packing. The trial recruited 433 people, who were randomly chosen to enter one of two groups; one to have their wound packed and the other to have no packing of the wound. After being discharged from hospital following surgery, the patients attended or were visited by a community nurse for the dressing to be changed or wound packed. Each patient provided information on pain from their wound, including worst pain each day and pain before, during, and after the changing of their dressing or packing. This and other information was gathered for the first 10 days after surgery and periodically until 6 months after surgery. The no-packing group experienced much less pain than the packing group. There was no difference in abscess recurrence and fistula formation between the non-packing and packing groups. The findings demonstrate that no packing of perianal abscess wounds after drainage operation is the best treatment.

Nosocomial transmission of COVID-19 puts patients with other medical problems at risk of severe illness and death. Of 662 inpatients with COVID-19 at an NHS Trust in South London, 45 (6.8%) were likely to have acquired COVID-19 in hospital. These patients had no evidence of respiratory or influenza-like illness on admission and developed symptoms, with positive SARS-CoV-2 PCR test results, more than 7 days after admission (>14 days for 38 [5.7%] patients). Forty (88.9%) of these patients had shared a ward with a confirmed COVID-19 case prior to testing positive. Implementation of a triage system combining clinical assessment with rapid SARS-CoV-2 testing facilitated cohorting so that fewer susceptible patients were exposed to COVID-19 on shared wards. With hospital service resumption alongside the possibility of future waves of COVID-19 related admissions, strategies to prevent nosocomial transmission are essential. Point-of-care diagnostics can complement clinical assessment to rapidly identify patients with COVID-19 and reduce risk of transmission within hospitals.

BACKGROUND: International medical graduates (IMGs) contribute significantly towards the NHS care provision. No standardised clinical orientation programme (COP) for IMGs new to the NHS exists. OBJECTIVE: Our objective was to describe recruitment and retention strategies for junior doctors (JDs) in general medicine and develop a framework to anticipate outcomes of these interventions using the realist evaluation methodology. METHODS: We performed quality improvement interventions of recruitment and COP for new entrant IMGs in our organisation employed between December 2017 and April 2019. RESULTS: Twenty-three IMGs were recruited, 96% successfully completed the COP with a mean contract duration of 13±5 months. From the academic year 2017/18 to 2018/19, mean JD post occupancy increased from 54±3 to 73±4 JDs (p<0.001) and JD locum spend fell by £1.9 million. CONCLUSION: Our structured COP provides a stable, trained and financially sustainable JD workforce. Application in broader NHS settings is recommended.
RESUMO
Since their introduction in 2006, the tyrosine kinase inhibitors (TKI) Sunitinib and Sorafenib have become the standard of care for many patients with renal cancer. They are generally well tolerated and have not been significantly implicated in renal toxicity. We report the first biopsy confirmed occurrence of acute interstitial nephritis in a patient receiving treatment with Sunitinib for metastatic renal cell cancer. However, two previous descriptions of interstitial nephritis related to treatment with TKIs, combined with this current report suggest that TKI therapy could be associated with this rare but life-threatening complication.

BACKGROUND: Carboxyl-ester lipase (CEL) contributes to fatty acid ethyl ester metabolism, which is implicated in alcoholic pancreatitis. The CEL gene harbours a variable number of tandem repeats (VNTR) region in exon 11. Variation in this VNTR has been linked to monogenic pancreatic disease, while conflicting results were reported for chronic pancreatitis (CP). Here, we aimed to investigate a potential association of CEL VNTR lengths with alcoholic CP. METHODS: Overall, 395 alcoholic CP patients, 218 patients with alcoholic liver cirrhosis (ALC) serving as controls with a comparable amount of alcohol consumed, and 327 healthy controls from Germany and the United Kingdom (UK) were analysed by determination of fragment lengths by capillary electrophoresis. Allele frequencies and genotypes of different VNTR categories were compared between the groups. RESULTS: Twelve repeats were overrepresented in UK ACP patients (P = 0.04) compared to controls, whereas twelve repeats were enriched in German ALC compared to alcoholic CP patients (P = 0.03). Frequencies of CEL VNTR lengths of 14 and 15 repeats differed between German ALC patients and healthy controls (P = 0.03 and 0.008, respectively). However, in the genotype and pooled analysis of VNTR lengths no statistical significant association was depicted. Additionally, the 16-16 genotype as well as 16 repeats were more frequent in UK ALC than in alcoholic CP patients (P = 0.034 and 0.02, respectively). In all other calculations, including pooled German and UK data, allele frequencies and genotype distributions did not differ significantly between patients and controls or between alcoholic CP and ALC. CONCLUSIONS: We did not obtain evidence that CEL VNTR lengths are associated with alcoholic CP. However, our results suggest that CEL VNTR lengths might associate with ALC, a finding that needs to be clarified in larger cohorts.

AIM: To investigate beta-catenin expression in patients with intestinal metaplasia, and to look for a possible relationship between beta-catenin expression and either epithelial proliferation values or Helicobacter pylori (H pylori) infection. METHODS: Twenty patients with complete type intestinal metaplasia were studied. beta-Catenin expression and epithelial cell proliferation in antral mucosa were assessed using an immunohistochemical analysis. H pylori infection was detected by histology and a rapid urease test. RESULTS: Reduced beta-catenin expression on the surface of metaplastic cells was detected in 13 (65%) out of 20 patients. Moreover, in eight (40%) patients intranuclear expression of beta-catenin was found. When patients were analyzed according to H pylori infection, the prevalence of both beta-catenin reduction at the cell surface and its intranuclear localization did not significantly differ between infected and uninfected patients. Cell proliferation was higher in patients with intranuclear beta-catenin expression as compared to the remaining patients, although the difference failed to reach the statistical significance (36+/-8.9 vs 27.2+/-11.4, P = 0.06). On the contrary, a similar cell proliferation value was observed between patients with reduced expression of beta-catenin on cell surface and those with a normal expression (28.1+/-11.8 vs 26.1+/-8.8, P = 0.7). H pylori infection significantly increased cell proliferation (33.3+/-10.2% vs 24.6+/-7.4%, respectively, P = 0.04). CONCLUSION: Both cell surface reduction and intranuclear accumulation of beta-catenin were detected in intestinal metaplasia. The intranuclear localization of beta-catenin increases cell proliferation. H pylori infection does not seem to play a direct role in beta-catenin alterations, whilst it significantly increases cell proliferation.
