Background In patients undergoing major liver resection, portal vein embolization (PVE) has been widely used to induce hypertrophy of the non-embolized liver in order to prevent post-hepatectomy liver failure. PVE is a safe and effective procedure, but does not always lead to sufficient hypertrophy of the future liver remnant (FLR). Hepatic vein(s) embolization has been proposed to improve FLR regeneration when insufficient after PVE. The sequential right hepatic vein embolization (HVE) after right PVE demonstrated an incremental effect on the FLR but it implies two different procedures with no time gain as compared to PVE alone. We have developed the so-called liver venous deprivation (LVD), a combination of PVE and HVE during the same intervention, to optimize the phase of liver preparation before surgery. The main objective of this randomized phase II trial is to compare the percentage of change in FLR volume at 3 weeks after LVD or PVE. Methods Patients eligible to this multicenter prospective randomized phase II study are subjects aged from 18 years old suffering from colo-rectal liver metastases considered as resectable and with non-cirrhotic liver parenchyma. The primary objective is the percentage of change in FLR volume at 3 weeks after LVD or PVE using MRI or CT-Scan. Secondary objectives are assessment of tolerance, post-operative morbidity and mortality, post-hepatectomy liver failure, rate of non-respectability due to insufficient FLR or tumor progression, per-operative difficulties, blood loss, R0 resection rate, post-operative liver volume and overall survival. Objectives of translational research studies are evaluation of pre- and post-operative liver function and determination of biomarkers predictive of liver hypertrophy . Sixty-four patients will be included (randomization ratio 1:1) to detect a difference of 12% at 21 days in FLR volumes between PVE and LVD. Discussion Adding HVE to PVE during the same procedure is an innovative and promising approach that may lead to a rapid and major increase in volume and function of the FLR, thereby increasing the rate of resectable patients and limiting the risk of patient’s drop-out. Trial registration This study was registered on clinicaltrials.gov on 15th February 2019 ( NCT03841305 ).

There are limited data on clinical profile of adolescent patients with Budd–Chiari syndrome (BCS). We studied clinical, radiological, thrombophilia profile and treatment outcomes in adolescent patients with BCS.MethodsForty-three consecutive patients of BCS with onset of symptoms during adolescence (10–19 years) were enrolled in the study. 129 randomly selected adult patients with BCS and 36 children with BCS formed the two control groups. The clinical history, physical examination, laboratory tests, thrombophilic disorders, radiological features and treatment outcomes of adolescents were compared to adults and children.ResultsIn adolescents, ascites (25/43 vs. 110/129, p = 0.0004) and thrombophilic disorders (16/43 vs. 93/129 p < 0.0001) were less frequent than adults. More adolescents (14/43) presented with hepatomegaly alone without ascites than adults (9/129, p < 0.001) or children (1/36, p = 0.005). Adolescents had lower Clichy scores [3.75 (1.2)] than adults [4.72 (1.3), p < 0.0001) or children [4.43 (1.7), p = 0.041]. JAK-2 V617F mutation was the most common thrombophilic disorder in adolescents (5/43) and more common than children (0/36, p = 0.043). Response to therapy was better in adolescents (74.4%) than children (52.8%, p = 0.038), but similar to adults (63.56%, p = 0.13).ConclusionDuring adolescence, patients with BCS present less commonly with ascites and may present with hepatomegaly alone. JAK-2 V617F mutation is the most common thrombophilic disorder during adolescence; though thrombophilic disorders are less common in adolescents than adults. Response to therapy is similar to adults, but better than children.

ObjectiveLeukaemia is the most common cancer of childhood, accounting for a third of cases. In order to assist clinicians in its early detection, we systematically reviewed all existing data on its clinical presentation and estimated the frequency of signs and symptoms presenting at or prior to diagnosis.DesignWe searched MEDLINE and EMBASE for all studies describing presenting features of leukaemia in children (0–18 years) without date or language restriction, and, when appropriate, meta-analysed data from the included studies.ResultsWe screened 12 303 abstracts for eligibility and included 33 studies (n=3084) in the analysis. All were cohort studies without control groups. 95 presenting signs and symptoms were identified and ranked according to frequency. Five features were present in >50% of children: hepatomegaly (64%), splenomegaly (61%), pallor (54%), fever (53%) and bruising (52%). An additional eight features were present in a third to a half of children: recurrent infections (49%), fatigue (46%), limb pain (43%), hepatosplenomegaly (42%), bruising/petechiae (42%), lymphadenopathy (41%), bleeding tendency (38%) and rash (35%). 6% of children were asymptomatic on diagnosis.ConclusionsOver 50% of children with leukaemia have palpable livers, palpable spleens, pallor, fever or bruising on diagnosis. Abdominal symptoms such as anorexia, weight loss, abdominal pain and abdominal distension are common. Musculoskeletal symptoms such as limp and joint pain also feature prominently. Children with unexplained illness require a thorough history and focused clinical examination, which should include abdominal palpation, palpation for lymphadenopathy and careful scrutiny of the skin. Occurrence of multiple symptoms and signs should alert clinicians to possible leukaemia.

The authors report on the clinical activity of a new oral inhibitor of Janus kinase 2 (JAK2) in patients with myelofibrosis. The drug improved a wide range of symptoms promptly, controlled them for >1 year, and appeared to inhibit disease progression to acute leukemia. Myelofibrosis is manifested as primary myelofibrosis, post–essential thrombocythemia myelofibrosis, or post–polycythemia vera myelofibrosis and is characterized by clinical signs (e.g., progressive anemia, bone marrow fibrosis, and splenomegaly) and a constellation of debilitating symptoms (fatigue, weakness, bone pain, a hypercatabolic state, and weight loss). 1 Survival in myelofibrosis is related to the number of risk factors and ranges from 2 to 4 years among patients with two or more risk factors (intermediate-2 or high risk) to 8 to 11 years among patients with no risk factors or one risk factor (intermediate-1 or low risk) (see Table 1A in the Supplementary Appendix, available with . . .

Soybean oil consumption is increasing worldwide and parallels a rise in obesity. Rich in unsaturated fats, especially linoleic acid, soybean oil is assumed to be healthy, and yet it induces obesity, diabetes, insulin resistance, and fatty liver in mice. Here, we show that the genetically modified soybean oil Plenish, which came on the U.S. market in 2014 and is low in linoleic acid, induces less obesity than conventional soybean oil in C57BL/6 male mice. Proteomic analysis of the liver reveals global differences in hepatic proteins when comparing diets rich in the two soybean oils, coconut oil, and a low-fat diet. Metabolomic analysis of the liver and plasma shows a positive correlation between obesity and hepatic C18 oxylipin metabolites of omega-6 (ω6) and omega-3 (ω3) fatty acids (linoleic and α-linolenic acid, respectively) in the cytochrome P450/soluble epoxide hydrolase pathway. While Plenish induced less insulin resistance than conventional soybean oil, it resulted in hepatomegaly and liver dysfunction as did olive oil, which has a similar fatty acid composition. These results implicate a new class of compounds in diet-induced obesity–C18 epoxide and diol oxylipins.

BackgroundThe association between COVID-19 infection and the development of autoimmune diseases is currently unknown, but there are already reports presenting induction of different autoantibodies by SARS-CoV-2 infection. Kikuchi-Fuimoto disease (KFD) as a form of histiocytic necrotizing lymphadenitis of unknown origin.ObjectiveHere we present a rare case of KFD with heart involvement after COVID-19 infection. To our best knowledge only a few cases of COVID-19-associated KFD were published so far. Based on presented case, we summarize the clinical course of KFD and its association with autoimmune diseases, as well we discuss the potential causes of perimyocarditis in this case.MethodsWe reviewed the literature regarding cases of “Kikuchi-Fujimoto disease (KFD)” and “COVID-19” and then “KFD” and “heart” or “myocarditis” by searching medical journal databases written in English in PubMed and Google Scholar.ResultsOnly two cases of KFD after COVID infection have been described so far.ConclusionSARS-CoV-2 infection can also be a new, potential causative agent of developing KFD.

Objective: Mauriac syndrome (MS) is a rare condition linked to inadequate glycemic control in type 1 diabetes mellitus (T1DM) and has also rarely been reported in patients with neonatal diabetes. MS manifests as growth failure, delayed puberty, cushingoid features, and hepatomegaly. The condition can be associated with complications like dyslipidemia, retinopathy, and nephropathy. The main objective of this study was to describe the magnitude of the condition, clinical features, management, and outcome of Sudanese children and adolescents with MS due to inadequate control of diabetes in our center. Study Design and Methods: This is a cross‐sectional hospital‐based study. All medical records of patients with MS were reviewed. Data, including demographics, clinical features, investigations, management, and outcome, were obtained. Patients were re‐educated and management intensified then followed up. Results: Thirty‐seven MS patients were enrolled in this study, with a male predominance of 59.5%. Neonatal diabetes was diagnosed in 5.4% of the patients, while others had T1DM. The median age at diagnosis of MS was 12 years. The diagnosis was based solely on clinical findings, including a history of prolonged unsatisfactory glycemic control, short stature, and hepatomegaly. Regarding the outcome, eight children (21.6%) were lost to follow‐up, one patient died (2.7%), seven (18.9%) had a static condition, and those who showed improvement were 21 (56.8%). Signs of improvement were a decrease in liver size with or without an increase in growth velocity. Nephropathy was the most common associated complication; it was seen in 33.3% of our cohort. Some got it at a very young age. Conclusions: Despite many efforts that have been made to achieve better glycemic control in children with T1DM, MS still exists in our setting. Though liver biopsy is the gold standard for diagnosis, being invasive, the diagnosis could be made conservatively, based on clinical features and response to treatment. The condition can be reversed with good metabolic control.

Congenital SyphilisA preterm baby boy was noted to have hepatomegaly on the first day of life. Radiographs of the baby’s legs showed periostitis and alternating dense and radiolucent bands in the distal femur.

Familial chylomicronemia syndrome (FCS) is a rare autosomal recessive disorder caused by mutations in lipoprotein lipase, resulting in accumulation of chylomicrons in plasma and hypertriglyceridemia. Elevated triglycerides cause several complications in patients, the most serious being episodes of acute pancreatitis. This review focuses on expert guidance and opinion from an experienced lipidologist and endocrinologist as well as a current review of the literature, as there are no specific guidelines on FCS. Discussion of expert guidance and opinion review of current literature. To date, there is no pharmacologic treatment for affected patients, and management options primarily include adoption of an extremely restricted, very-low-fat diet, along with avoidance of certain medications and alcohol. Endocrinologists often diagnose and manage patients with metabolic disorders, including patients with high triglyceride levels, but rare diseases like FCS can be missed or poorly evaluated due to knowledge gaps about disease state. Given endocrinologists' role in the treatment of lipid disorders, it is important that they understand the clinical signs and symptoms of FCS to correctly diagnose patients. Patients with FCS can be identified based on a defined clinical criteria and a thorough review of medical history, after excluding differential diagnoses and secondary factors. Typical manifestations include hypertriglyceridemia characterized by lipemic serum, history of abdominal pain, and acute/recurrent pancreatitis. Secondary factors to be excluded are pregnancy, alcohol abuse, uncontrolled diabetes, and use of certain medications. FCS is a rare, inherited lipid disorder disease that often goes underdiagnosed and unmanaged. This review provides a summary of clinical characteristics of FCS that can be potentially used to screen patients in an endocrinologist's office and direct them to the appropriate standard of care. apoB = apolipoprotein B; apoC-III = apolipoprotein CIII; ASO = antisense oligonucleotide; FCS = familial chylomicronemia syndrome; HTG = hypertriglyceridemia; LPL = lipoprotein lipase; LPLD = lipoprotein lipase deficiency.

The clinical manifestations of coronavirus disease 2019 (COVID-19) are non-specific and multi-inflammatory. They vary from mild to severe manifestations that can be life-threatening. The association of SARS-CoV-2 infection and pseudoaneurysm formation or rupture of an already existing aneurysm is still unexplored. Several mechanisms may be involved, including the direct destruction to the artery by the viral infection or through the release of the inflammatory cytokines. We are presenting a case of a 13-year-old girl with a ruptured cerebral pseudoaneurysm of the left middle cerebral artery (M2 segment) with severe intracerebral hemorrhage as the earliest manifestation of COVID-19 infection.
