Diagnostic Laparoscopy in Patients With Peritoneal Carcinomatosis Is Safe and Does Not Delay Cytoreductive Surgery With Hyperthermic Intraperitoneal Chemotherapy

Background Outcomes of cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) among patients with peritoneal carcinomatosis (PC) depend largely on the extent of peritoneal disease. Since PC is not reliably evaluated with cross-sectional imaging, tumor burden is often evaluated with diagnostic laparoscopy (DLS). The aims of this study are to evaluate the safety of DLS in patients with peritoneal disease and determine if DLS delays time to CRS-HIPEC. Methods We performed an institutional retrospective review of 145 patients who underwent CRS-HIPEC between 2013 and 2020. Patients were divided into 2 groups: those who underwent an electively scheduled DLS prior to CRS-HIPEC and those who did not. Intraoperative and postoperative complications associated with DLS were determined from the surgeon’s operative report. Time from diagnosis of PC to CRS-HIPEC was compared between the 2 groups. Results Of the 145 patients available for analysis, 47% (68) underwent DLS and 44% (64) did not. Of all the diagnostic laparoscopies performed, there was 1 (1.5%) intraoperative complication. The duration between diagnosis of peritoneal carcinomatosis and surgery was 4.9 months among patients who underwent DLS prior to CRS-HIPEC and 4.3 months among patients who did not ( P = .79). Conclusion In this retrospective analysis, diagnostic laparoscopy prior to CRS-HIPEC demonstrated a comparable rate of DLS-associated complications compared to other gastrointestinal malignancies and does not prolong time from diagnosis to CRS-HIPEC. Thus, in patients undergoing evaluation for CRS-HIPEC, diagnostic laparoscopy provides significant value in patient selection without incurring perioperative risk or delay in CRS-HIPEC.

Prevalence and outcome of abdominal vascular injury in severe trauma patients based on a TraumaRegister DGU international registry analysis

This study details the etiology, frequency and effect of abdominal vascular injuries in patients after polytrauma based on a large registry of trauma patients. The impact of arterial, venous and mixed vascular injuries on patients’ outcome was of interest, as in particular the relevance of venous vessel injury may be underestimated and not adequately assessed in literature so far. All patients of TraumaRegister DGU with the following criteria were included: online documentation of european trauma centers, age 16–85 years, presence of abdominal vascular injury and Abbreviated Injury Scale (AIS) ≥ 3. Patients were divided in three groups of: arterial injury only, venous injury only, mixed arterial and venous injuries. Reporting in this study adheres to the STROBE criteria. A total of 2949 patients were included. All types of abdominal vessel injuries were more prevalent in patients with abdominal trauma followed by thoracic trauma. Rate of patients with shock upon admission were the same in patients with arterial injury alone (n = 606, 33%) and venous injury alone (n = 95, 32%). Venous trauma showed higher odds ratio for in-hospital mortality (OR: 1.48; 95% CI 1.10–1.98, p = 0.010). Abdominal arterial and venous injury in patients suffering from severe trauma were associated with a comparable rate of hemodynamic instability at the time of admission. 24 h as well as in-hospital mortality rate were similar in in patients with venous injury and arterial injury. Stable patients suspected of abdominal vascular injuries should be further investigated to exclude or localize the possible subtle venous injury.

Sedation Mode During Endovascular Stroke Treatment in the Posterior Circulation—Is Conscious Sedation for Eligible Patients Feasible?

Background and Purpose: To compare safety and efficacy of conscious sedation (CS) vs. general anesthesia (GA) in endovascular stroke treatment (EST) of the posterior circulation (PC).Methods: Retrospective single-center analysis of patients receiving EST for large-vessel occlusion (LVO) in PC between January 2015 and November 2020. Exclusion criteria were severe stroke syndromes (NIHSS > 20), decreased level of consciousness, intubation for transport, and second stroke within 3 months of follow-up. The primary endpoint was a favorable clinical outcome 90 days after stroke onset (mRS 0–2 or 3 if pre-stroke mRS 3). Secondary endpoints were the rate of EST failure and procedural complications.Results: Of 111 included patients, 45/111 patients (40.5%) were treated under CS and 60/111 (54.0%) under GA. In 6/111 cases (5.4%), sedation mode was changed from CS to GA during EST. Patients treated under CS showed a lower mRS 90 days after stroke onset [mRS, median (IQR): 2.5 (1–4) CS vs. 3 (2–6) GA, p = 0.036] and a comparable rate of good outcome [good outcome, n (%): 19 (42.2) CS vs. 15 (32.6) GA, p = 0.311]. There was no difference in complication rates during EST (6.7% CS vs. 8.3% GA) or intracranial bleeding in follow-up imaging [n (%): 4 (8.9) CS vs. 7 (11.7) GA), p = 0.705]. The rate of successful target vessel recanalization did not differ (84.4% CS vs. 85.0 % GA).Conclusions: In this retrospective study, EST of the posterior circulation under conscious sedation was for eligible patients comparably safe and effective to patients treated under general anesthesia.

Limited benefit of additional contrast-enhanced CT to end-of-treatment PET/CT evaluation in patients with follicular lymphoma

Despite follicular lymphoma (FL) is frequently characterized by a moderate increase of glucose metabolism, PET/CT examinations provides valuable information for staging and response assessment of the disease. The aim of the study was to assess and compare the diagnostic performance of PET/ldCT and PET/ceCT, respectively, in evaluating FL patients at the end of treatment. Fifty FL consecutive patients who underwent end-of-therapy PET/CT with both ldCT and ceCT were analyzed. Two blinded observers independently assessed PET/ldCT and PET/ceCT applying the Deauville score (DS) and Lugano classification criteria. PET imaging obtained after the end-of-treatment (EoT) was classified as showing PET and ce-CT matched response (concordant imaging group, CIG) or PET and ce-CT unmatched response (discordant imaging group, DIG). Relapse rate and Event-Free Survival (EFS) were compared between CIG and DIG patients. Overall, no differences in metabolic response classification were observed between PET/ldCT and PET/ceCT. In 13 (26%) patients PET/ceCT identified additional FDG-negative nodal lesions in mesenteric, retroperitoneal and iliac regions. However, in all cases, final DS remained unchanged and the additional results did not modify the following therapeutic decision. Among patients, who obtained complete metabolic response a comparable rate of relapse was registered in DIG 3/13 (23%) and CIG subgroups 5/20 (25%) [p = 0.899]. In all 3 DIG cohort patients who relapsed the recurrent disease involved also, but not exclusively, PET negative lymph nodes detected by ceCT. In overall population metabolic response defined by PET/ldCT predicted EFS [76% (group of patients with metabolic response) vs 35% (group of patients with residual disease), p = 0.0013] significantly better than ceCT-Based response assessment [75% (group of patients with complete response) vs 53% (group of patients with residual disease), p = 0.06]. Our study demonstrates a negligible diagnostic and predictive value of ceCT performed in addition to standard 18FDG PET/ldCT for EoT response evaluation in FLs. PET/ldCT should be performed as first-line imaging procedure, also in patients with prevalent abdominal and pelvic involvement, limiting the acquisition of ceCT in selected cases. This tailored approach would contribute to avoid useless radiation exposure and preserve renal function of patients.

Fracture fixation in extremity trauma with carbon fiber-reinforced polyetheretherketone (CFR-PEEK) plates: evidence today

Purpose To compare the CFR-PEEK plates with conventional plates in fracture fixation with regards to clinical and radiological outcomes and complications. Methods A systematic literature search was conducted in four online databases independently by two reviewers using the Cochrane methodology for systematic reviews. The identified relevant studies were assessed against predetermined inclusion/exclusion criteria. Independent data extraction and assessment of risk of bias and study quality was carried out. Results Nine studies (patient n = 361) out of 6594 records were included for analysis: 2 RCTs (n = 63), 3 prospective cohort studies (n = 151), and 4 retrospective cohort studies (n = 147). Studies were grouped per anatomic area of fixation. Four studies (n = 200) examined fixation of proximal humerus fractures. Two studies (n = 74) examined fixation of distal radius fractures. Two studies (n = 53) assessed outcomes of fixation of distal femur fractures. One study (n = 87) assessed the outcomes of fixation of ankle fractures. All nine studies reported very high union rates (from 91% in distal femur to 100% in upper limb) for the CFR-PEEK plate groups and low complication rates. There was no significant difference in clinical outcomes, and rate of complications as compared to the conventional plate groups. Conclusion CFR-PEEK plates have high union rates in extremity fracture fixation similar to conventional plates with comparable good clinical outcomes and a very low and comparable rate of complications. Considering their advantages, CFR-PEEK plates seem to be valid alternative to conventional plating.

101 Paediatric Burns and The Coronavirus Pandemic: Were Children Staying Safe in Lockdown or Did The Virus Increase Burns Admissions?

Aim We aimed to identify if there was a change in the number of paediatric burns during the coronavirus pandemic and whether there was a change in the management of said burns. Method Data on ten parameters for all burns assessed on the Burns Unit at Alder Hey Children’s Hospital from April to May of 2020 was collected and compared to the same period from 2019. Results There was a decrease in the number of patients presenting to hospital, down to 24 from 32 in 2019. Scald injuries increased to 67% compared to 44%, while all other mechanisms of injuries decreased. Fewer very small burns (<1% TBSA) presented to hospital (28%) compared to 50% the previous year. There was an overall increase in the presentation of burns greater than 1% TBSA (1-5% TBSA increased to 47% from 31%; 5-10% TBSA increased to 19% from 3%; 10-20% TBSA increased to 6% from 3%). A comparable rate of burns was managed conservatively as an outpatient (89% vs 88%), admitted for dressing changes (81% vs 78%), and managed surgically (11% vs 13%). Conclusions The coronavirus pandemic resulted in a decrease in the number of children experiencing burns, while at the same time causing an increase in the number of scald injuries. Our data showed no significant change in the management of burns indicating that regardless of the pandemic, paediatric burns were managed appropriately as per national guidelines.

Safety and discontinuation rate of immune checkpoint inhibitors used in patients with solid and hematological malignancies. A population based retrospective analysis

Background The discovery of immune checkpoint inhibitors caused a paradigm shift in cancer treatment and led to a major improvement in clinical outcomes. However, they may induce inflammatory side effects that are known as immune-related adverse effect (iRAE). This study aimed to assess the safety profile and discontinuation rate of immune checkpoint inhibitors in cancer patients. Methods Adult cancer patients ≥18 years who received at least one dose of immune-checkpoint inhibitor (ICI) were included. The primary endpoint was the rate of permanent discontinuation of immune checkpoint inhibitors due to immune-related adverse effects. The secondary endpoints were rate and type of specific organ iRAEs, interventions used to treat specific organ iRAEs, and discontinuation rate of immune checkpoint inhibitors due to disease progression. Results A total of 75 patients were included in the study with a median age of 60 years [IQR: 46-72 years]. Of 75 patients, 7 patients (9.33%) have permanently discontinued ICIs due to immune-related adverse effects. Seven iRAEs occurred in the 7 patients who have permanently discontinued ICIs. Steroids were the main treatment used for 8 patients, followed by levothyroxine for 2 patients and one patient did not receive any medication. The discontinuation rate due to disease progression was reported in 32 patients (42.66%). Conclusion Immune checkpoint inhibitors were well tolerated in the majority of our patient population with a comparable rate of immunerelated adverse effects in comparison to the published data. Corticosteroids were fundamentally used to treat immune-related adverse effects.

Thromboembolic and Bleeding Events in COVID-19 Patients receiving Extracorporeal Membrane Oxygenation

Background Extracorporeal membrane oxygenation (ECMO) is a potential treatment option in critically ill COVID-19 patients suffering from acute respiratory distress syndrome (ARDS) if mechanical ventilation (MV) is insufficient; however, thromboembolic and bleeding events (TEBE) during ECMO treatment still need to be investigated. Methods We conducted a retrospective, single-center study including COVID-19 patients treated with ECMO. Additionally, we performed a univariate analysis of 85 pre-ECMO variables to identify factors influencing incidences of thromboembolic events (TEE) and bleeding events (BE), respectively. Results Seventeen patients were included; the median age was 57 years (interquartile range [IQR]: 51.5–62), 11 patients were males (65%), median ECMO duration was 16 days (IQR: 10.5–22), and the overall survival was 53%. Twelve patients (71%) developed TEBE. We observed 7 patients (41%) who developed TEE and 10 patients (59%) with BE. Upper respiratory tract (URT) bleeding was the most frequent BE with eight cases (47%). Regarding TEE, pulmonary artery embolism (PAE) had the highest incidence with five cases (29%). The comparison of diverse pre-ECMO variables between patients with and without TEBE detected one statistically significant value. The platelet count was significantly lower in the BE group (n = 10) than in the non-BE group (n = 7) with 209 (IQR: 145–238) versus 452 G/L (IQR: 240–560), with p = 0.007. Conclusion This study describes the incidences of TEE and BE in critically ill COVID-19 patients treated with ECMO. The most common adverse event during ECMO support was bleeding, which occurred at a comparable rate to non-COVID-19 patients treated with ECMO.

Neonatal and Pediatric Emergency Room Visits in a Tertiary Center during the COVID-19 Pandemic in Italy

The COVID-19 pandemic is affecting healthcare services worldwide. We investigated the impact of a strict lockdown policy on the characteristics of neonatal and pediatric attendances to our pediatric emergency department (PED). The clinical features of PED visits in March–April 2020 (COVID-19) and March–April 2019 (non-COVID-19) were analyzed. During the COVID-19 lockdown period, visits reduced by 67%, from 3159 to 1039. Neonatal access decreased from 78 to 59, mainly due to fewer pathological conditions, with a complete disappearance of respiratory infections. On the other hand, minor neonatal clinical conditions rose from 44 (56.4%) to 48 (81.4%), mostly due to feeding-related issues. Communicable diseases, particularly respiratory infections and gastroenteritis, dropped from 1552 (49.1%) to 288 (27.7%). Accident-related visits also decreased during COVID-19, from 535 (16.9%) to 309 (29.7%), becoming the most common cause of PED access. Hospital admissions reduced from 266 to 109, while PICU (pediatric intensive care unit) admissions decreased from 27 to 11, with a comparable rate of 10.1% in both periods. The lockdown due to COVID-19 had a substantial impact on our PED visits, which markedly decreased, mainly due to fewer respiratory infections. Unexpectedly, neonatal visits for minor conditions did not decline, but rather slightly increased. Among the children admitted to the PICU, none had respiratory disease.
