BACKGROUND: Vertebrobasilar junction aneurysms occur rarely, but have a higher rupture rate than supratentoral aneurysms, and higher morbidity and mortality. Their location ventral to the neuroaxis makes them a challenging surgical lesion. METHODS: In this paper, we share our experience with the surgical technique for the management of these complex aneurysms. CONCLUSION: An in-depth understanding of the anatomy of these aneurysms, careful preoperative planning, and a meticulous surgical technique, including knowledge of every detail of the procedure-positioning, an advanced skull base technique, and careful aneurysm dissection and clipping-is essential for a successful outcome of the surgery...

Patients with rectal cancer have an increased risk of developing sexual disorders. These dysfunctions are caused by the disease itself (negative psychological impact, nerve compression in the pelvis), as well as by the treatments (radiotherapy, chemotherapy and surgery). Most sexual disorders are due to the surgery and can be attributed to injuries of the retroperitoneal nerves. Sexuality assessment of patients before and after treatment, a precise knowledge of the pelvic anatomy by the surgeon, and an appropriate care by specialists (gynaecologists, urologists and sexologists) are essential to reduce the risk of sexual disorders and to minimize their impact on overall quality of life...

The prevention and management of myocardial ischemia/reperfusion (MI/R) injury is an essential part of coronary heart disease surgery and is becoming a major clinical problem in the treatment of ischemic heart disease. Previous studies by our group have demonstrated that pigment epithelium‑derived factor (PEDF) improves cardiac function in rats with acute myocardial infarction and reduces hypoxia‑induced cell injury. However, the protective function and mechanisms underlying the effect of PEDF in MI/R injury remain to be fully understood...

Electrical stimulation mapping (ESM) of the brain remains a major procedure for guiding epilepsy and tumor surgeries. This article collates available experiences and data in ESM to develop a guide for conducting the procedure. There are many factors that influence the yield of ESM. The stimulation parameters offered in this article need to be adjusted within safe limits to address the factors. Each ESM procedure should be tailored to the patient's age and baseline mental or psychological capacity. Stimulation-induced seizures and EEG afterdischarges disrupt ESM procedure and render the interpretation of the results difficult...

Brain tissue analysis is highly desired in neurosurgery, such as tumor resection. To guarantee best life quality afterward, exact navigation within the brain during the surgery is essential. So far, no method has been established that perfectly fulfills this need. Optical coherence tomography (OCT) is a promising three-dimensional imaging tool to support neurosurgical resections. We perform a preliminary study toward in vivo brain tumor removal assistance by investigating meningioma, healthy white, and healthy gray matter...

RATIONALE: Retrograde gastroesophageal intussusception (RGEI) is a relatively rare gastrointestinal (GI) disorder in which a portion of the stomach wall invaginates into the esophagus. More recently, peroral endoscopic myotomy (POEM) has emerged as an endoscopic alternative to surgical myotomy for achalasia, and, to the best of our knowledge, our case is the first RGEI after POEM to be reported. PATIENT CONCERNS: A 22-year-old male was presented with a history of vomiting, intractable retching and hematemesis for 3 days...

Recently, the incidence and prevalence of inflammatory bowel disease (IBD) have been increasing in worldwide, especially in Asian area. IBD is a chronic and progressive disease eventually causing bowel damage. The advance in the treatment of IBD over the past several decades has been achieved with the development of biologics. Furthermore, goals for management of IBD have been evolving from symptom-based management to mucosal healing, which can reduce the surgery rate and hospitalization. To treat the patients with IBD properly, identification of risk factors of patients should be preceded...

TMPRSS3 (Trans-membrane Serine Protease 3) is a type II trans-membrane serine protease that has proteolytic activity essential for hearing. Mutations in the gene cause non-syndromic autosomal recessive deafness (DFNB8/10) in humans. Knowledge about its cellular distribution in the human inner ear may increase our understanding of its physiological role and involvement in deafness, ultimately leading to therapeutic interventions. In this study, we used super-resolution structured illumination microscopy for the first time together with transmission electron microscopy to localize the TMPRSS3 protein in the human organ of Corti...

Background: Essential tremor (ET) is among the most common neurological diseases and it often runs in families. How knowledgeable ET patients and their families are about their disease has been the subject of surprisingly little scholarship. Methods: To fill this gap in knowledge, we administered a comprehensive 32-item survey (i.e., questions about etiology, pathophysiology, symptoms and signs, natural history, and treatments) to 427 participants, including 76 ET probands, 74 affected relatives (AFRs), 238 unaffected relatives, and 39 spouses of unaffected relatives, all of whom were participating in two ET family studies...

BACKGROUND: Inadequate anatomic knowledge has been cited as a major contributor to declining surgical resident operative competence. We analyzed the impact of a comprehensive, procedurally oriented cadaveric procedural anatomy dissection laboratory on the operative performance of surgery residents, hypothesizing that trainees' performance of surgical procedures would improve after such a dissection course. MATERIALS AND METHODS: Midlevel general surgery residents (n = 9) participated in an 8 wk, 16-h surgery faculty-led procedurally oriented cadaver simulation course...

Introduction: Persons with paraplegia present complex challenges to anaesthetists. Complications experienced by these patients can require major orthoplastic surgery such as excision of infected bone and soft tissue due to pressure sores and soft tissue reconstruction. Anaesthetic strategies deemed both safe and acceptable to this population are essential. Case presentation: We report a case series of five procedures in four patients with complete chronic spinal cord injury (CSCI) who underwent operations in lateral position under standby anaesthesia and audio-visual distraction (AVD) with minimal sedation...

INTRODUCTION: Malignant pleural mesothelioma (MPM) is a quite rare cancer, but with increasing incidence, that is usually induced by previous asbestos exposure. Its prognosis is poor and there is no validated curative therapy to date. Surgery of MPM, done only by few expert teams within a multimodal treatment is of limited and still disputed value. The standard treatment of MPM, relying on first-line chemotherapy by combined cisplatin-pemetrexed is often poorly effective, even if combination with bevacizumab anti-VEGF antibodies has slightly improved the results...

Professor Zofia Umiastowska Sawicka laid the foundations for modern pediatric surgery in Poland, first in Bialystok, and subsequently in Kielce. She was a student of Prof. Jan Kossakowski from Warsaw Medical University to be counted among his most talented and skilled disciples. Professor Umiastowska became the head of the first Department of Pediatric Surgery in Bialystok, which was later incorporated into the Medical Academy of Bialystok. In 1977 she moved to Kielce to run the Department of Pediatric Surgery until her retirement in 1991...

BACKGROUND: Overconfidence is the tendency to overestimate the knowledge, capacity, or performance one really possesses. This cognitive bias could be potentially dangerous in medical decision-making, considering the impact it could have on patient health care. The aim of this study was to evaluate the incidence of overconfidence and underconfidence in medical student knowledge on general surgery by using traditional and new statistical approaches. METHODS: During the application of a multiple-choice examination, 251 next-to-graduate medical students were invited to express the accuracy of their responses by choosing their own perceived confidence level for a set of questions...

Critically ill acute high-risk abdominal surgery patients represent a major challenge to health care providers, with the typical patient being elderly and frail, and with severe and multiple comorbidities. The mortality rate in this population is high, and the postoperative course is characterized by complications, prolonged hospitalisation and considerable risk of permanent disability. With an ageing population, the number of elderly patients, as well as challenges concerning treatment will arise, calling for a coordinated effort both nationally and internationally to enhance treatment in this vulnerable patient group...

Our knowledge on intracranial pain-sensitive structures in humans comes essentially from observations during neurosurgical procedures performed in awake patients. It is currently accepted that intracranial pain-sensitive structures are limited to the dura mater and its feeding vessels and that small cerebral vessels and pia mater are insensitive to pain, which is inconsistent with some neurosurgical observations during awake craniotomy procedures. We prospectively collected observations of painful events evoked by mechanical stimulation (touching, stretching, pressure, or aspiration) of intracranial structures during awake craniotomies, routinely performed for intraoperative functional mapping to tailor brain tumour resection in the eloquent area...
