Benign liver tumours (BLT) are increasingly diagnosed as incidentalomas. Clinical implications and management vary across and within the different types of BLT. High-quality clinical practice guidelines are needed, because of the many nuances in tumour types, diagnostic modalities, and conservative and invasive management strategies. Yet, available observational evidence is subject to interpretation which may lead to practice variation. Therefore, we aimed to systematically search for available clinical practice guidelines on BLT, to critically appraise them, and to compare management recommendations.

A scoping review was performed within MEDLINE, EMBASE, and Web of Science. All BLT guidelines published in peer-reviewed, and English language journals were eligible for inclusion. Clinical practice guidelines on BLT were analysed, compared, and critically appraised using the Appraisal of Guidelines, Research and Evaluation (AGREE II) checklist regarding hepatic haemangioma, focal nodular hyperplasia (FNH), ce standards and identify unmet needs in research. This may ultimately contribute to improved global patient care.

Recognising differences in recommendations can assist in harmonisation of practice standards and identify unmet needs in research. This may ultimately contribute to improved global patient care.We present a 73-year-old woman who presented with a pathological fracture of her right humerus. Further imaging and biopsy indicated a mucinous adenocarcinoma of the lung as the primary neoplasm. This represents the first published case of a mucinous adenocarcinoma of the lung presenting as a metastatic lesion of the humerus. Operative management of pathological fractures of the humerus has typically included either intramedullary nailing or the use of single-plating or double-plating techniques. The authors describe a novel technique using both intramedullary fixation augmented with a locking plate, steel cables and bone cement, with good outcome.We present a case of laparoscopic cholecystectomy with subarachnoid block (SAB) in an opioid-tolerant patient with chronic obstructive pulmonary disease (COPD). A 64-year-old woman presented to the emergency department with acute abdominal pain of biliary colic. Surgery was delayed in favour of conservative management given that she was considered high risk for general anaesthesia. Due to refractory pain, she successfully proceeded to have laparoscopic cholecystectomy with SAB. This case is a timely reminder that SAB is feasible and safe in patients with severe COPD, with the added benefit of increased analgesic effects, fewer postoperative pulmonary complications and quick recovery time.A 22-year-old woman was diagnosed with thyrotoxicosis 8 weeks after the diagnosis of a mild COVID-19 infection. She had reported significant unexplained weight loss after testing positive for COVID-19, but failed to seek medical attention. She recovered well from COVID-19, but presented to the emergency department with worsening symptoms of thyrotoxicosis after 2 months. In view of her known history of previously treated Graves' disease, a recurrence of Graves' thyrotoxicosis was suspected. A positive thyroid stimulating hormone receptor antibody confirmed the diagnosis. She was started on carbimazole and propranolol treatment with significant improvement of her symptoms.A 35-year-old Chinese man with no risk factors for stroke presented with a 2-day history of expressive dysphasia and a 1-day history of right-sided weakness. The presentation was preceded by multiple sessions of neck, shoulder girdle and upper back massage for pain relief in the prior 2 weeks. CT of the brain demonstrated an acute left middle cerebral artery infarct and left internal carotid artery dissection. MRI cerebral angiogram confirmed left carotid arterial dissection and intimal oedema of bilateral vertebral arteries. In the absence of other vascular comorbidities and risk factors, massage-induced internal carotid arterial dissection will most likely precipitate the near-fatal cerebrovascular event. The differential diagnosis of stroke in a younger population was consequently reviewed and discussed.Infected pancreatic necrosis is a postpancreatitis complication that is mainly caused by Enterobacteriaceae and Enterococci. Here, we have reported a very rare case of Lactobacillus paracasei bacteraemia associated with infected pancreatic necrosis and retroperitoneal abscess. In addition to the diagnosis of diabetic ketoacidosis, blood test results revealed a high inflammatory status. CT of the abdomen revealed pancreatic walled-off necrosis. Blood culture and aspiration fluid culture revealed positivity for L. paracasei, leading to the diagnosis of infected pancreatic necrosis. The abscess had spread in the retroperitoneal space later. The patient recovered after receiving antibiotic treatment and endoscopic and percutaneous drainage. L. paracasei can cause invasive infection, including infected pancreatic necrosis and retroperitoneal abscess, which requires aggressive therapy.We describe a case of a woman in her 80s with persistent atrial fibrillation (AF) despite being on flecainide who was admitted for AF with rapid ventricular response. Attempts with direct-current cardioversions were unsuccessful despite increased doses of the antiarrhythmic therapy. At atrioventricular (AV) nodal ablation, very high right ventricular capture thresholds resulted in abortion of the procedure as back-up ventricular pacing could not be assured with adequate margin for safety. Veliparib concentration Shortly following the electrophysiology (EP) study, the patient developed cardiogenic shock with new apical left ventricular regional wall motion abnormality suggestive of apical ballooning and a toxic-appearing wide QRS complex electrocardiogram (EKG). The patient was successfully treated with sodium bicarbonate infusion for presumed flecainide toxicity. The regional wall motion abnormality and EKG changes resolved along with normalisation of capture thresholds after 2 days of treatment. The patient underwent an uncomplicated successful AV nodal ablation several weeks later.Rectal laceration in the absence of concurrent anal sphincter injury at the time of parturition is not a frequently reported finding. This rarely encountered injury is also referred to as a buttonhole injury. It is a disruption of the vaginal and rectal tissue with resultant disruption of the anal epithelium in the setting of an intact external anal sphincter. A 30-year-old gravida 1 para 0 at 39 weeks presented for induction of labour due to chronic hypertension. During her labour course, she developed with superimposed preeclampsia with severe features and magnesium sulfate was initiated. She underwent a spontaneous vaginal delivery of an infant weighing 3840 g. Following delivery, stool was visualised in the vagina. A rectal examination revealed a rectovaginal defect separate from the second-degree perineal laceration, which extended proximally to the cervix. The anal sphincter was noted to be intact with good tone. Both defects were repaired, and she had an uncomplicated recovery.

There is an urgent need to assess the impact of immunosuppressive therapies on the immunogenicity and efficacy of SARS-CoV-2 vaccination.

Serological and T-cell ELISpot assays were used to assess the response to first-dose and second-dose SARS-CoV-2 vaccine (with either BNT162b2 mRNA or ChAdOx1 nCoV-19 vaccines) in 140 participants receiving immunosuppression for autoimmune rheumatic and glomerular diseases.

Following first-dose vaccine, 28.6% (34/119) of infection-naïve participants seroconverted and 26.0% (13/50) had detectable T-cell responses to SARS-CoV-2. Immune responses were augmented by second-dose vaccine, increasing seroconversion and T-cell response rates to 59.3% (54/91) and 82.6% (38/46), respectively. B-cell depletion at the time of vaccination was associated with failure to seroconvert, and tacrolimus therapy was associated with diminished T-cell responses. Reassuringly, only 8.7% of infection-naïve patients had neither antibody nor T-cell responses detected following second-dose vacciner serological non-responders should be investigated as means to induce more robust immunological response.

Despite growing interest, there is no guidance or consensus on how to conduct clinical trials and observational studies in populations at risk of rheumatoid arthritis (RA).

An European League Against Rheumatism (EULAR) task force formulated four research questions to be addressed by systematic literature review (SLR). The SLR results informed consensus statements. One overarching principle, 10 points to consider (PTC) and a research agenda were proposed. Task force members rated their level of agreement (1-10) for each PTC.

Epidemiological and demographic characteristics should be measured in all clinical trials and studies in at-risk individuals. Different at-risk populations, identified according to clinical presentation, were defined asymptomatic, musculoskeletal symptoms without arthritis and early clinical arthritis. Study end-points should include the development of subclinical inflammation on imaging, clinical arthritis, RA and subsequent achievement of arthritis remission. Risk factors should bek of RA.

To compare the treatment efficacy and safety of tofacitinib (TOF) versus methotrexate (MTX) in Takayasu arteritis (TAK).

Fifty-three patients with active disease from an ongoing prospective TAK cohort in China were included in this study. Twenty-seven patients were treated with glucocorticoids (GCs) and TOF, and 26 patients were treated with GCs with MTX. The observation period was 12 months. Complete remission (CR), inflammatory parameter changes, GCs tapering and safety were assessed at the 6th, 9th and 12th month. Vascular lesions were evaluated at the 6th and 12th month, and relapse was analysed during 12 months.

The CR rate was higher in the TOF group than in the MTX group (6 months 85.19% vs 61.54%, p=0.07; 12 months 88.46% vs 56.52%, p=0.02). During 12 months' treatment, patients in the TOF group achieved a relatively lower relapse rate (11.54% vs 34.78%, p=0.052) and a longer median relapse-free duration (11.65±0.98 vs 10.48±2.31 months, p=0.03). Average GCs dose at the 3rd, 6th and 12th month was lower in the TOF group than that in the MTX group (p<0.05). A difference was not observed in disease improvement or disease progression on imaging between the two groups (p>0.05). Prevalence of side effects was low in both groups (3.70% vs 15.38%, p=0.19).

TOF was superior to MTX for CR induction, a tendency to prevent relapse and tapering of the GCs dose in TAK treatment. A good safety profile for TOF was also documented in patients with TAK.

A good safety profile for TOF was also documented in patients with TAK.Systemic therapy of Gram-negative sepsis remains challenging. Polymyxin B (PMB) is well suited for sepsis therapy due to the endotoxin affinity and antibacterial activity. However, the dose-limiting toxicity has limited its systemic use in sepsis patients. For safe systemic use of PMB, we have developed a nanoparticulate system, called D-TZP, which selectively reduces the toxicity to mammalian cells but retains the therapeutic activities of PMB. D-TZP consists of an iron-complexed tannic acid nanocapsule containing a vitamin D core, coated with PMB and a chitosan derivative that controls the interaction of PMB with endotoxin, bacteria, and host cells. D-TZP attenuated the membrane toxicity associated with PMB but retained the ability of PMB to inactivate endotoxin and kill Gram-negative bacteria. Upon intravenous injection, D-TZP protected animals from pre-established endotoxemia and polymicrobial sepsis, showing no systemic toxicities inherent to PMB. These results support D-TZP as a safe and effective systemic intervention of sepsis.
