Gross total resection with fluorescence could lead to improved overall survival rates: a systematic review and meta-analysis.

INTRODUCTION: Glioblastoma cases are often treated with aggressive resection. Recent studies have suggested that extended surgical resection could improve survival. Improved extent of resection could be afforded by the use of fluorescence during surgery. We aimed to examine the effect of fluorescence on the results of gross total resection (GTR) and its impact on the overall survival (OS) and progression-free survival (PFS) rates. METHODS: We performed a literature search of studies published between 2000 and 2021. The study followed the PRISMA guidelines and focused on newly-diagnosed glioblastoma cases. The collected data were divided into two groups according to the fluorescence use: Group A (standard white-light use) and Group B (fluorescent-light use). RESULTS: The results showed a superiority of the fluorescence use during surgery for newly diagnosed glioblastoma cases concerning the procurement of GTR. Additionally, we highlighted the importance of GTR on the OS but not on the PFS rate. We found that the use of 5-aminolevulinic acid resulted in better OS rates compared to fluorescein sodium. CONCLUSION: GTR is a significant factor leading to improved OS; nevertheless, it was an apparently unrelated factor for estimating the PFS rate. Fluorescence use during surgery could lead to higher rates of complete resection and better OS rates.

A Custom-Made Treovance® Abdominal Aortic Aneurysm Endograft to Correct Late Failure of Trombone Technique with a Tube Endograft.

BACKGROUND: Unfavorable anatomy is one of the major limitations of endovascular aortic aneurysm repair (EVAR) with specifically adverse proximal neck morphology excluding many patients from receiving the standard endograft devices. Thoracic tube endografts have been used to overcome the issue of wide infrarenal necks, either as a sole device (single tubes or double tubes using the trombone technique) or as the proximal part of a bifurcated device fixed to the aortic bifurcation or infrarenally oriented. However, custom-made large proximal diameter bifurcated endograft designs have never been used. METHODS: We present the case of a 56-year-old man with Marfan syndrome, suffering abdominal aortic aneurysm (AAA) enlargement from a type Ib endoleak after previous EVAR with 2 Endofit tube endografts (trombone technique). He was considered unfit for open surgery while possible alternatives such as fenestrated endovascular AAA repair and chimney technique were excluded. RESULTS: The patient was treated with a custom-made 44-mm proximal diameter, bifurcated Bolton Medical Treovance device with technical and clinical success. No immediate or perioperative complications were noted. Follow-up after 6 months showed graft patency and no endoleak of any type. CONCLUSIONS: This alternative technique for hostile proximal neck management is promising and needs long-term follow-up; an issue which is discussed within the broader context of custom-made device regulations.

Positional Changes of an Endurant Endograft Leading to Simultaneous Ipsilateral Iliac Limb Obstruction and Contralateral Type IIIa Endoleak.

We report the case of a 79-year-old man who was admitted to our department with acute limb ischemia due to the occlusion of the left iliac limb of an Endurant endograft. The admission computed tomography angiography revealed also a type IIIa endoleak due to modular disconnection of the iliac extensions from the right iliac limb of the endograft main body. Interestingly, during the 4-year post-endovascular aneurysm repair period, an increased kinking of the right limb has been observed leading to an almost cross-limb configuration of the limbs at the time of complications. To our knowledge, this is the first case in the literature of the simultaneous presence of limb thrombosis and late type IIIa endoleak with this particular device. The ischemia was treated with a femoro-femoral cross-over bypass, and the endoleak was corrected with the position of 2 Endurant iliac limb extensions bridging the dislocated endograft pieces.

"Security dilemma": active immunotherapy before versus after radiation therapy alone or chemo-radiotherapy for newly diagnosed glioblastoma.

Management of glioblastoma should be aggressive and personalised to increase the quality of life. Many new therapies, such as active immunotherapy, increase the overall survival, yet they result in complications which render the search for the optimal treatment stra-tegy challenging.

Anatomical Localization of Traumatic Brain Injury Cases in Eastern Macedonia and Thrace, Greece: a 10-year Retrospective Observational Study.

OBJECTIVE: Brain trauma is an extremely important economical and social issue with increasing daily incidence. It is important to observe and report brain trauma, in order to provide better conditions for improvement of the trauma prevention and management. METHODS: A ten-year retrospective observational analysis was performed on 292 (fatal and non-fatal) incidents of traumatic brain injury among 2,847 totally examined cases in the records of the laboratory of forensic sciences at Democritus University of Thrace between January 1, 2007 and December 31, 2016. The results were further analyzed and classified into pertinent categories associated with the purpose of the study. RESULTS: The average age was estimated at 47.24 years with an obvious male domination. The most common cause of TBI, according to the results, is transport accidents (61.85%) followed by trauma inflicted by blunt instrument (22.49%), fall from height (11.65%) and occupational accidents (4.02%). Mortality rates were evaluated for each type, revealing extremely disturbing numbers. Regarding the anatomical localization on the skull, the most common region of cranial fractures is the cranial base (16.48%), followed by the frontal (12.87%), occipital (11.29%) and parietal bones (11.06%). In the majority of the cases, there were associated injuries. CONCLUSION: The management of traumatic brain injuries is difficult and sometimes impossible. Better prevention measures are required to minimize as much as possible the incidence of brain trauma.

Does Nationality Matter for the Gunshot Brain Injury? Ten-Year Retrospective Observational Cadaveric Comparative Study for Gunshot TBI between Greece and Bulgaria.

OBJECTIVE: Penetrating brain trauma (PBT) caused by gunshot is one of the most lethal traumatic brain injuries (TBIs) and its management and confrontation is of great importance. METHODS: The authors searched retrospectively the archives from 2 similar autonomous laboratories of forensic science and toxicology in the Balkan peninsula for a 10-year period of time and included only fatal penetrating brain injuries. RESULTS: The study is conducted in 61 cadavers with gunshot PBT. All of the cadavers were victims of suicide attempt. The most common anatomical localization on the skull were the facial bones, followed by skull base, temporal and parietal bone, conducting a trajectory of the gunshot. Additional findings were atherosclerosis of the blood vessels and chronic diseases such as chronic obstructive pulmonary disease, cancer and fatty liver. CONCLUSION: PBI has a high mortality rate. There are factors and findings from the collected data differing between the 2 aforementioned nations. Either way, better preventative measures, gun control and healthcare system are highly necessary.

The Clock Is Ticking - Brain Atrophy in Case of Acute Trauma?

OBJECTIVE: Brain atrophy and brain herniation are gaining a lot of attention separately, but a limited amount of studies connected them together, and because of this, we are going to review and examine the subject in the current meta-analysis. METHODS: The authors collected data reporting brain atrophy of alcoholic and schizophrenic cause, as well as data on control patients, all of which was published on MEDLINE between 1996 and 2018. The included 11 articles were processed with a statistical program. RESULTS: We found that the pericerebral space is unequal among the groups, while the intracranial volume is strongly correlated to the biggest foramen of the body. The effect of this inequality, however, is expressed in emergency cases, where the patients with brain atrophy will have more time before the final stage of brain herniation. CONCLUSION: The current study raises a controversial issue that requires careful investigation and high attention from the health care personnel.
