[Simultaneous robotic-assisted radical prostatectomy and robot-assisted transabdominal preperitoneal inguinal hernia repair].

Introduction: An inguinal hernia is frequently identified in men with prostate cancer, which is likely due to similar risk factors, including age, gender and smoking.

Aim: To assess the safety and feasibility of performing concomitant robotic-assisted radical prostatectomy (RARP) and robotic-assisted transabdominal preperitoneal (TAPP) inguinal hernia repair.

Materials And Methods: We retrospectively analyzed the treatment outcomes of 23 patients who underwent RARP between January 2022 and June 2023.

[Minimizing the number of trocars during laparoscopic partial nephrectomy. Surgical technique].

Introduction: During last 20 years in urology there has been a number of significant advancements, which were due to the introduction into practice and improvement of minimally invasive techniques. Development of laparoscopic surgery allowed to actively introduce these procedures in various kidney disorders, including renal tumors. Laparoscopic partial nephrectomy is also undergoing changes in order to improve the technique.

[Robot-assisted left-side partial nephrectomy with a segmental resection of left lower ureter and Boari reconstruction].

Renal cell carcinoma (RCC) accounts for more than 90% of cases of malignant kidney tumors and represents 2-3% of all malignancies worldwide. Clear cell renal cell carcinoma (ccRCC), the most common type of RCC, comprising 70-80% of cases. RCC most commonly metastasizes to the lungs, bones, lymph nodes, liver, adrenal glands, and brain.

Velocity map imaging with no spherical aberrations.

Velocity map imaging (VMI) is a powerful technique to deduce the kinetic energy of ions or electrons that are produced from a large volume in space with good resolution. The size of the acceptance volume is determined by the spherical aberrations of the ion optical system. Here we present an analytical derivation for velocity map imaging with no spherical aberrations.

Cascade Infrared Thermal Photon Emission.

The later stages of cooling of molecules and clusters in the interstellar medium are dominated by emission of vibrational infrared radiation. With the development of cryogenic storage it has become possible to experimentally study these processes. Recent storage ring results demonstrate that intramolecular vibrational redistribution takes place within the cooling process, and an harmonic cascade model has been used to interpret the data.

Synergetic effect of Au nanoparticles and transition metal phosphides for enhanced hydrogen evolution from ammonia-borane.

The hydrogen evolution from ammonia borane is intriguing but challenging due to its sluggish kinetics. In this regard, the gold nanoparticles amalgamation with metal phosphides is speculated to be more efficient catalysts. Here, the catalysts Au/NiP and Au/CoP with the high synergetic effect of Au nanoparticles and metal phosphides were synthesized for ammonia borane hydrolysis.

Paratrigeminal, Paraclival, Precavernous, or All of the Above? A Circumferential Anatomical Study of the C3-C4 Transitional Segment of the Internal Carotid Artery.

Background: Although the term paraclival carotid pervades recent skull base literature, no clear consensus exists regarding boundaries or anatomical segments.

Objective: To reconcile various internal carotid artery (ICA) nomenclatures for transcranial and endoscopic-endonasal perspectives, we reexamined the transition between lacerum (C3) and cavernous (C4) segments using a C1-C7 segments schema. In this cadaveric study, we obtained a 360°-circumferential view integrating histological, microsurgical, endoscopic, and neuroradiological analyses of this C3-C4 region and identified a distinct transitional segment.

The Interlenticulostriate Approach to Very High-Riding Distal Basilar Trunk Aneurysms.

Background: Most high-riding distal basilar trunk aneurysms can be surgically approached via the transsylvian route and its orbitozygomatic variant. However, on rare occasions, the basilar bifurcation may be unusually high and an approach above the carotid terminus may be required.

Objective: In this cadaveric study, we sought to determine the feasibility and exposure limits of the interlenticulostriate approach (ILSA).

The Medial Extra-Sellar Corridor to the Cavernous Sinus: Anatomic Description and Clinical Correlation.

Objective: The zenith of surgical interest in the cavernous sinus peaked in the 1980s, as evidenced by reports of 10 surgical triangles that could access the contents of the lateral sellar compartment (LSC). However, these transcranial approaches later became marginalized, first by radiosurgery's popularity and lower morbidity, and then by clinical potential of endoscopic corridors noted in several qualitative studies. Our anatomic study, taking a contemporary look at the medial extra-sellar corridor, gives a detailed qualitative-quantitative analysis for its use with increasingly popular endoscopic endonasal approaches to the cavernous sinus.

[SURGICAL TREATMENT OF AN ACUTE MESENTERIAL ISCHEMIA].

Experience of surgical treatment of 143 patients, suffering an acute mesenterial ischemia, was summarized. Isolated intestinal resection was performed in 41 patients (lethality 65.9%), intestinal resection with the mesenterial vessels thrombembolectomy--in 9 (lethality 33.

Medial and Superior Orbital Decompression: Improving Access for Endonasal Endoscopic Frontal Sinus Surgery.

Objective: Visualization by Draf I-III endoscopic access to the frontal sinus via drainage pathways is sometimes inadequate. We compare lateral frontal sinus exposures by Draf approaches versus our modification of removing the medial-superior wall of the orbit while preserving the periorbita.

Methods: Twenty cadaveric heads dissected using Draf IIB, III, and modified Draf III with medial and superior orbital decompression (MSOD) underwent thin-cut computed tomography (CT) scanning.

Prognostic significance of the markers IDH1 and YKL40 related to the subventricular zone.

Glioblastoma multiforme (GBM), a highly aggressive brain cancer characterized by uncontrolled proliferation, resistance to cell death, angiogenesis, and vascular edema, remains one of the deadliest types of cancer. The subventricular zone (SVZ) harbors cells with great proliferative potential, and the microenvironment within the SVZ is permissive to growth and proliferation. This neurogenic niche is suspected to be a vulnerable site for the origin of subtypes of GBM.

The extended transorbital craniotomy: an anatomic study.

Background: Supra-/transorbital approaches are mostly limited to suprasellar and anterior fossa pathologies, whereas lateral supraorbital approaches provide less retrosellar exposure and less overall operative volume, especially in the temporal region.

Objective: Our cadaveric study proposes removal of the lesser and greater wings of the sphenoid bone to increase both the lateral angle typically achieved with pterional approaches and exposure to the temporal lobe and perisellar region.

Methods: In 5 cadaveric specimens, our 3 steps to expand transorbital exposures included the following: step 1, standard transorbital craniotomy via a 3-cm supra-eyebrow incision; step 2, removal of the lesser sphenoid wing completed extradurally; and step 3, partial removal of the greater sphenoid wing.

Comparing operative exposures of the le fort I osteotomy and the expanded endoscopic endonasal approach to the clivus.

Objectives We compare surgical exposures to the clivus by Le Fort I osteotomy (LFO) and the expanded endoscopic endonasal approach (EEEA). Methods Ten cadaveric specimens were imaged with 1.25-mm computed tomography.

Endoscopic, endonasal variability in the anatomy of the internal carotid artery.

Background: Classic three-dimensional schemas of the internal carotid artery (ICA) for transcranial approaches do not necessarily apply to two-dimensional endoscopic views. Modifying an existing ICA segment classification, we define endoscopic orientation for the lacerum (C3) to clinoid (C5) segments through an endonasal approach.

Methods: In 20 cadaveric heads, we classified endoscopic appearance based on shape and angulation of C3 to C5 segments.

Endoscopic endonasal approach to the maxillary strut: anatomical review and case series.

Objectives/hypothesis: The maxillary strut is the bone that separates the foramen rotundum and superior orbital fissure. Tumors involving the lateral wall of the sphenoid sinus, posterior ethmoid, or posterior maxillary sinus may invade this region. The authors detail the anatomy of the strut and present a case series that emphasizes the importance and utility of this useful landmark during an endoscopic endonasal approach to lesions in this region.

The carotid siphon: a historic radiographic sign, not an anatomic classification.

Background: After the term carotid siphon was introduced by Moniz in 1927 to describe the radiographic appearance of the intracranial internal carotid artery (ICA), the concept gained popularity in decades following in both the anatomic and the medical literature. However, as conflicting definitions persist in the delineation of proximal and distal sites, does the term carotid siphon provide the precision needed for current anatomic and clinical studies?

Methods: A PubMed search of "carotid siphon" detected >400 articles from the anatomic and medical literature during the past 6 decades. Moniz's text and figures in his original Lancet article and a compilation of other seminal historical articles and references were reviewed to trace the use of the term carotid siphon during this period.

[Efficacy of the immunomodulating therapy in complex treatment of gastric cancer complicated by acute hemorrhage using radical operations].

The results of radical operative treatment of 10 patients, suffering gastric cancer, complicated by an acute hemorrhage, using immunomodulating therapy, were presented. The immunomodulator application have promoted the natural cells-killers cytological activity raising, the tumoral antigens (AG) elimination, as well as to enhance the neutrophils bactericidal and phagocytic activity, the circulating immune complexes (AG+IgG), (AG+IgM) formation and their deducing from an organism.

A comparison of cryopreserved vein allografts and prosthetic grafts for hemodialysis access.

In hemodialysis patients with insufficient vasculature for creation of a native arteriovenous fistula (AVF), a polytetrafluoroethylene (PTFE) graft is commonly utilized. Because of PTFE complications, our group and others have used cryopreserved cadaver femoral vein allografts (Synergraft [SYN], CryoLife, Marietta, GA) in selected patients. Based on our experience with these allografts, we hypothesized that they were more resistant to thrombosis than PTFE grafts.

Experience with cryopreserved cadaveric femoral vein allografts used for hemodialysis access.

The purpose of this study was to review the patency and complications of cryopreserved vein allografts used for hemodialysis access, and to compare them to a group with polytetrafluoroethylene (PTFE) grafts. Patients without adequate vasculature for native fistula were implanted with vein allografts or PTFE grafts at the surgeon's discretion. Only cryopreserved (CRY) veins were used until January 2001, when decellularized, cryopreserved Synergraft (SYN) veins became available.

Decellularized cadaver vein allografts used for hemodialysis access do not cause allosensitization or preclude kidney transplantation.

Background: Dimethyl sulfoxide-cryopreserved (CRY) cadaver vein allografts used for hemodialysis access in patients with renal failure recently have been shown to cause broad recipient allosensitization, measured by panel reactive antibody (PRA) assay. Synergraft (SYN) processing is a novel method of treating tissue that decellularizes the graft (including mismatched major histocompatibility antigens) and potentially should prevent allosensitization.

Methods: Twenty hemodialysis patients underwent placement of an SYN-processed cadaver vein allograft.
