ence-based medicine.

While there has been some improvement in the level of evidence in the craniomaxillofacial trauma literature over the past 2 decades, the current quality remains low, and further progress is needed to support the practice of evidence-based medicine.

To evaluate the effects of incremental doses of acepromazine on hemodynamics in isoflurane-anesthetized dogs.

Prospective, experimental study.

Healthy, adult, mixed-breed dogs (two male and four female) weighing 16.8 ± 5.1 kg (mean ± standard deviation).

Dogs were anesthetized with propofol (7 mg kg

) intravenously (IV) and isoflurane. Thermodilution and arterial catheters were placed for hemodynamic monitoring and arterial blood sampling for blood gas analysis. Baseline measurements were performed with stable expired concentration of isoflurane (Fe'Iso) at 1.8%. Each dog was then administered four incremental acepromazine injections (10, 15, 25 and 50 μg kg

) IV, and measurements were repeated 20 minutes after each acepromazine injection with Fe'Iso decreased to 1.2%. The four acepromazine injections resulted in cumulative doses of 10, 25, 50 and 100 μg kg

(time points ACP

, ACP

, ACP

and ACP

, respectively).

Compared with baseline, cardiac index (CI) increased significantly by 34%, whereaat ACP50 and ACP100. Under the conditions of this study, acepromazine administration did not change blood pressure.

The need for preservation(P) or removal(R) of articular cartilage during disarticulations remains unanswered.

Medline database was used to conduct a systematic review regarding all types of minor disarticulations and some types of major disarticulations in patients with diabetes mellitus, peripheral arterial disease or trauma related disarticulations. Fisher-exact statistical test was used to perform calculations for the entire group as for subgroups.

A total of 444 disarticulations at the Chopart joint, ankle and knee were included (P = 255 vs. R = 189). BAY218 There was no difference in wound healing, functionality and mortality. Reamputation rate was lower in the P-group (9.4% vs. 16.9%). Infection rate was not significantly different. Differences in reamputations (R = 10.6% vs. P = 1.0%) and infections (R = 4.4% vs. P = 22.6%) were only present for the ankle subgroup.

There is no difference in wound healing, functionality and mortality between the preservation and removal of articular cartilage in the lower limb.

With this study, we performed a systematic review of the literature and ongoing clinical trials on convalescent plasma therapy in pediatric patients with COVID-19. The electronic databases Medline PubMed, Scopus, and Web Of Science were searched. Also, clinical trials registries were searched for potentially eligible studies. A total of 90 records were retrieved after duplicate removal. Eight studies were case reports of children treated with convalescent plasma therapy (14 children, age range, 9 weeks to 18 years); 5 children had a chronic disease. During the hospital stay, 5 received drugs (e.g., remdesivir) in addition to convalescent plasma therapy. No convalescent plasma therapy-related adverse events were reported in 5 studies and 3 made no mention of adverse events. Seven studies concluded that convalescent plasma therapy is or could be a useful therapeutic option; one study made no claims. Only 3 of the 13 retrieved trials underway were planned exclusively for children. This is the first systematic review of the literature regarding convalescent plasma therapy for COVID-19 in children. We found insufficient clinical information on the safety and efficacy of convalescent plasma therapy in children. Nevertheless, the positive outcomes of the few case reports published to date suggest that convalescent plasma therapy may be of potential benefit. Further research with well-designed and powered clinical trials is needed.The room temperature storage used for platelets worldwide leads to platelet storage lesion (PSL) and risk of bacterial growth, limiting platelet shelf life and safety in transfusion. Thus, there is a need for an alternative storage method that can serve as effective temperature storage for platelet concentrates (PCs). In the previous investigation, we have shown that N-acetylcysteine (NAC) is a potential candidate for an additive solution to retain platelet characteristics during cold storage for up to 5 days. However, the study partially describes the efficacy and has drawbacks to address. Here, we used the apheresis platelet product with 50 mM NAC and stored up to 10 days under refrigerated condition (4 ± 1 °C). Stored platelet concentrates were analyzed for critical parameters such as platelet activation, annexin V binding, sialic acid, reactive oxygen species (ROS), neuraminidase activity, and in vivo efficacy using Prkdcscid mice. Investigation observations revealed that PCs with NAC showed reduced platelet activation, annexin V binding, ROS production, and sialic acid levels. in vivo recovery of PCs showed similar recovery rates stored PCs irrespective of treatment or storage condition. However, on the tenth day after 24 h, recovery in room temperature stored concentrates was about 32 %, whereas in NAC treated refrigerated concentrates, it stands at 47 %. These observations indicate that NAC addition protects refrigerated concentrates during long-term storage retaining the platelet integrity. The study also suggests that extending PC storage beyond 10 days is practically accomplishable with efficacy similar to room temperature (RT) stored PCs.

IBD management has been significantly affected during the COVID-19 lockdown with potential clinical issues.

The aim of this study was to analyse the impact of COVID-19 pandemic on the Italian paediatric IBD cohort.

This was a multicentre, retrospective, cohort investigation including 21 different Italian IBD referral centres. An electronic data collection was performed among the participating centres including clinical characteristics of IBD patients, number of COVID-19 cases and clinical outcomes, disease management during the lockdown and the previous 9 weeks.

2291 children affected by IBD were enrolled. We experienced a significant reduction of the hospital admissions [604/2291 (26.3%) vs 1281/2291 (55.9%); p<0.001]. More specifically, we observed a reduction of hospitalizations for new diagnosis (from n = 44 to n = 27) and endoscopic re-evaluations (from n = 46 to n = 8). Hospitalization for relapses and surgical procedures remained substantially unchanged. Biologic infusions did not significantly vary [393/2291 (17.1%) vs 368/2291 (16%); p = 0.3]. Telemedicine services for children with IBD were activated in 52.3% of the centres. In 42/2291(1.8%) children immunosuppressive therapies were adapted due to the concurrent COVID-19 pandemic.

Due to the several limitations of the lockdown, cares for children with IBD have been kept to minimal standards, giving priorities to the urgencies and to biologics' infusions and implementing telemedicine services.

Neoadjuvant therapy prior to resection of adenocarcinoma of the pancreatic head increases time to surgery and thus the possibility of biliary complications. We hypothesized that biliary complications during neoadjuvant therapy negatively impact clinical outcomes.

We completed a retrospective study of a cohort of borderline resectable patients consistently treated with neoadjuvant therapy from May 2014 through March 2019. Biliary complications were defined as new-onset biliary obstruction, existing stent failure, cholecystitis, and cholangitis.

Of 59 patients that met inclusion criteria, 34 (57.6%) went on to resection. Biliary complications affected 16 patients (27%); 8 (50%) of these patients went on to surgical resection. Of those 43 patients who did not have a biliary intervention, 26 went on to surgical resection (60.4%). There was no significant effect of a biliary complication on total number of chemotherapy cycles (p=0.12), proceeding to surgical resection (p=0.56) or on median survival (p=0.23). Among patients who did proceed to surgery, there was a notable difference in median survival for patients who required a biliary intervention (17.9 vs 31.0 months) that did not reach significance (p=0.35).

The need for further biliary interventions during neoadjuvant therapy for pancreatic adenocarcinoma is common, but does not appear to have a significant effect on number of cycles of neoadjuvant therapy or proceeding to surgical resection. Larger studies are necessary to determine if these events compromise overall survival.

Extrahepatic portal vein obstruction (EHPVO) causes portal hypertension in noncirrhotic children. Among surgical treatments, it is unclear whether the meso-Rex shunt (MRS) or portosystemic shunt (PSS) offers lower post-operative morbidity and superior patency over time. Our objective was to evaluate long-term outcomes comparing MRS and PSS for pediatric patients with EHPVO.

A systematic review was conducted of articles reporting children undergoing surgical shunts for EHPVO from 1/2000-2/2020. Of 87 articles screened, 22 were eligible for inclusion. The primary outcome was shunt thrombosis and secondary outcomes included non-operative complications, stenosis, and re-operation.

Eighteen of 22 studies were of good quality and four had fair quality. Of 461 patients included, 340 underwent MRS and 121 underwent PSS. MRS were associated with a higher rate of post-operative thrombosis when compared to PSS (14.1% vs 5.8%, p=0.021). There were 40/340 MRS patients (11.8%) that required at least one re-operation for either shunt thrombosis or stenosis, versus 5/121 PSS patients (4.1%), p=0.019.

Both MRS and PSS result in acceptable long-term patency rates, but the more technically demanding MRS is associated with higher post-shunt thrombosis, often requiring further operative intervention. This study suggests that PSS may offer advantages for pediatric patients with EHPVO.

The aim of this review was to explore the demographics, types of injury, and complications of traumatic maxillofacial and brain injuries, in order to contribute to comprehensive health strategies. The PubMed and Scopus databases were systematically searched. Inclusion criteria were clinical studies investigating combined traumatic maxillofacial and brain injuries. Exclusion criteria were duplicates, non-English publications, non-full-text publications, publication date before 1990, and studies with insufficient data. Of the 754 articles identified, 15 eligible articles representing 1421 cases were included. The mean age was 38.3 years. Most cases were male (79%). The most common mechanism of injury was traffic accidents (53.4%). The most common fracture pattern was middle third fractures (52.4%). Seven studies had an explicit definition for TBI, using the Glasgow Coma Score (GCS), radiological evidence, and/or specific symptoms.
