The management practices of liver abscess (LA) have evolved over time. The precise diagnosis of etiology and complications is pivotal for appropriate management.

Descriptive analyses of consecutive patients treated for LA using electronic medical records at a liver unit between years 2010 and 2020 and investigate relationships between clinical, imaging, laboratory and microbiological findings, treatment strategies and mortality.

Of 1630 LA patients, the most common aetiologies were amoebic liver abscess (ALA; 81%) and pyogenic liver abscess (PLA; 10.3%, mainly related to biliary disease and/or obstruction). Abdominal pain (86%) and fever (85.3%) were the commonest presenting symptoms (median duration-10 days). Almost 10% had jaundice at presentation, 31.1% were diabetic, 35.5% had chronic alcohol use and 3.3% had liver cirrhosis. Nearly 54% LA were solitary, 77.7% localized to the right liver lobe (most commonly segment VII/VIII). Patients with large LA (>10cm, 11.9%) had more frequent jaundice and aich if given early improve treatment outcomes. Presence of jaundice, liver cirrhosis and septic encephalopathy were independent predictors of mortality.
The commonest presentation was middle age male with right lobe solitary ALA. Patients with large, bilobar and/or pyogenic abscess had more complications. Nearly 70% patients require percutaneous interventions, which if given early improve treatment outcomes. Presence of jaundice, liver cirrhosis and septic encephalopathy were independent predictors of mortality.
Percutaneous ablation is an important part of management strategy for liver tumors. While radiofrequency ablation and microwave ablation are the most widely used ablative techniques, cryoablation (CA) has several technical advantages but has been underused till recently. In this study, we report the initial experience with percutaneous CA of liver tumors.

This was a retrospective evaluation of consecutive patients with liver tumors who underwent percutaneous CA between October 2018 and August 2019. The ablation procedures were performed under combined ultrasound and computed tomography guidance using argon-helium-based CA systems. The baseline tumor characteristics (including size and location), Barcelona Clinic Liver Cancer stage, and Child-Pugh score were recorded. Each patient underwent a follow-up after 1 month and at 3 months subsequently. Technical success, complete response, local tumor progression, and overall survival were evaluated.

Nine patients (mean age, 62.4 years, median age, 66 years, fi safe and effective ablative technique.
Transarterial chemoembolization (TACE) is the most common locoregional therapy for hepatocellular carcinoma (HCC). Postembolization syndrome is not an uncommon complication. At present, there is no specific treatment for management of this complication. We aimed to study the role of N-acetyl cysteine (NAC), an antioxidant, in management of this complication.

In a prospective observational study, consecutive patients with HCCundergoing TACE from January 2016 to January 2017 were included. Patients with postembolization syndrome, defined as an elevation of transaminase levels more than 3-4 times the upper limit of normal, were administered intravenous NAC for 72h (150mg/kg for 1h, then 12.5mg/kg/h for 4h, and continuous infusion 6.25mg/h for the remaining 67h). The other group received only supportive standard of care. The primary end point was reduction in post-TACE transaminitis.

Of 112 patients with HCC, 53 (47.3%) received NAC. The majority were cirrhotics in both the groups. Both groups were well matched in demographic, laboratory, and tumor characteristics. In the NAC group, there was significant reduction in Aspartate transaminase (AST) and Alanine transaminase (ALT) levels from day 1 to day 3 (p= 0.000) compared with the non-NAC group, with no significant change in bilirubin or international normalized ratio levels. The duration of hospital stay was similar in both the groups. None had any major adverse events to NAC.

This is a prospective, single-center experience, showing that early initiation of N-acetyl cysteine in those with post-TACE embolization syndromereduces the transaminase level significantly.

Etiology of and outcomes following idiosyncratic drug-induced liver injury (DILI) vary geographically. We conducted a prospective study of DILI in India, from 2013 to 2018 and summarize the causes, clinical features, outcomes and predictors of mortality.

We enrolled patients with DILI using international DILI expert working group criteria and Roussel Uclaf causality assessment method. Follow-up was up to 3 months from onset of DILI or until death. Multivariate logistics regression was carried out to determine predictors of non-survival.

Among 1288 patients with idiosyncratic DILI, 51.4% were male, 68% developed jaundice, 68% required hospitalization and 8.2% had co-existing HIV infection. Concomitant features of skin reaction, ascites, and encephalopathy (HE) were seen in 19.5%, 16.4%, and 10% respectively. 32.4% had severe disease. Mean MELD score at presentation was 18.8±8.8. Overall mortality was 12.3%; 65% in those with HE, 17.6% in patients who fulfilled Hy's law, and 16.6% in those that developed 3-month mortality was approximately 12%. Hy's law, presence of jaundice or MELD were predictors of mortality.
In India, ATD, CAM, AED, anti-metabolites and ART account for the majority of cases of DILI. The 3-month mortality was approximately 12%. Hy's law, presence of jaundice or MELD were predictors of mortality.Coronavirus disease 2019 (COVID-19) is associated with a significant morbidity and mortality in patients with cirrhosis. There is a significantly higher morbidity and mortality due to COVID-19 in patients with decompensated cirrhosis as compared to compensated cirrhosis, and in patients with cirrhosis as compared to non-cirrhotic chronic liver disease. The fear of COVID-19 before or after liver transplantation has lead to a significant reduction in liver transplantation numbers, and patients with decompensated cirrhosis remain at risk of wait list mortality. The studies in liver transplantation recipients show that risk of mortality due to COVID-19 is generally driven by higher age and comorbidities. The current review discusses available literature regarding outcomes of COVID-19 in patients with cirrhosis and outcomes in liver transplant recipients.
Use of a relatively larger glenosphere with some larger overhang helps to minimize posterior impingement and some degree of glenoid lateralization is also beneficial in reverse shoulder arthroplasty (RSA). The optimal amounts of inferior overhang and lateralization are not agreed upon. The purpose of this in-vitro biomechanical study is to analyze the effect of glenosphere size and glenoid lateralization on deltoid load, focusing on differences in its three distinct heads.

Reverse shoulder arthroplasty (DeltaXtend, Fa. Depuy/Synthes) was performed on six cadaveric specimens. The load on each head of the deltoid muscle (spinalis, acromialis, and clavicularis) was measured indirectly by transferring deformation (μm/m) via strain gauges (Fa. Vishay) with stepwise lateralization +0mm (subgroup I), +5mm (subgroup II), +10mm (subgroup III). Each scenario was done with a 38mm (group A) and a 42mm (group B) glenosphere.

In group A as well in group B, the mean measured deformation in the respective titanium omega increased with lateralization in the clavicular (AI 119.6μm/m, AIII 307.3μm/m; BI 173.3μm/m, BIII 358.5μm/m), in the spinal (AI 85.3μm/m, AIII 188.5μm/m; BI 138.8μm/m, BIII 261.2μm/m) and in the acromial head (AI 340.5 μm/μ; AIII 454.2μm/m; BI 388.5μm/m, BIII 538.8μm/m). A significant difference between the subgroups in the spinal (p=.048) and clavicular heads (p=.028) was found. buy Bay K 8644 The use of a 42mm glenosphere increased significantly the load in each segment.

Lateralization and glenosphere size increased significantly deltoid muscle loading, especially in the clavicular head. According to these in-vitro data, the high variability in the amount of lateralization influences thesoft-tissue balance in reverse shoulder arthroplasty.

the increasing number of joint arthroplasties and high-activity patients led to progressive developments of bearing surfaces to improve performance and durability. Different strategies such as crosslinking UHMWPE (HXLPE) and the addition of vitamin-E (HXLPE) have been tested to improve wear and oxidation resistance.

Recent innovations about UHMWPE showed improvements either for hip and knee, with the potential of long-term survivorship.

We clarify the functional and the clinical anatomy of obturator externus. We performed cadaveric studies and investigated clinically in primary THA cases. The location, trajectory, and size of the muscular tendon was recorded. The trajectory of the obturator externus ran orthogonal to the femoral axis with the hip in 90° flexion whereas that of the obturator internus muscle ran parallel. Because the trajectory of obturator externus and the obturator internus differ, their functions also differ.For septic arthritis of the knee, we attempted to determine the preferred surgical technique in the United-States (US), the believed "gold-standard" treatment among others. This was performed by an electronic-survey distributed to all academic orthopaedic faculty throughout the US. The preferred method was arthroscopy (69.8%). Arthroscopy is believed to be the gold-standard in 27.0%, arthrotomy in 29.4%, while 43.5% believe no gold-standard exists. In conclusion the majority of surgeons prefer arthroscopy when managing a native, septic knee in an adult patient. However, there is no national consensus on a gold-standard treatment or the role of synovectomy.
Currently there is significant controversy regarding which fixation method is most effective for the treatment of syndesmotic ankle injuries.

This meta-analysis was designed to compare the metal screw, dynamic, and bioabsorbable screw fixation methods for treatment of syndesmotic ankle injuries.

An online search for RCT and prospective/retrospective clinical comparison studies between January 1998 and December 2018 on syndesmotic fixation was conducted. The main parameters collected include functional scores, mean time to full weightbearing, postoperative tibiofibular clear spaces, tibiofibular overlap, medial clear spaces, and complication rates. Statistical analysis was conducted using One Way ANOVAs and Chi-Squared tests using Review Manager and Excel.

A total of 18 comparison studies, with 509 patients in the metal screw fixation group, 275 in the dynamic fixation group, and 226 in the bioabsorbable screw fixation group, were included in this meta-analysis. For the metal screw group, dynamic fixation group, and bioabsorbable screw group, the mean AOFAS score were 83.
