A 69-year-old man was admitted to our hospital with acute epigastric discomfort and subsequent paraplegia. Computed tomography revealed acute type B aortic dissection with a thrombosed false lumen. Magnetic resonance imaging did not reveal spinal cord infarction. Paraplegia resolved completely within 1 h. However, on the following day, the patient developed motor impairment in the left leg, sensory disorder of the bilateral legs and urinary retention. The symptoms gradually improved with conservative medical therapy...

OBJECTIVES: For a moderately dilated ascending aorta (diameter 35-54 mm), current guidelines recommend continuous annual or semi-annual examinations with computed tomography or magnetic resonance imaging. However, few data have shown the yield and benefit of such a protocol. This study aimed to investigate the fate of a moderately dilated ascending aorta and thereby determine the adequate imaging interval. METHODS: In our institutional database, we identified adult patients having an ascending aortic diameter ≥40 mm in contrast-enhanced computed tomography and follow-up imaging(s) after ≥1 year...

The strictly regulated unidirectional differentiation program in some somatic stem/progenitor cells has been found to be modified in the ectopic site (tissue) undergoing regeneration. In these cases, the lineage barrier is crossed by either heterotypic cell fusion or direct differentiation. Though studies have shown the role of coordinated genetic and epigenetic mechanisms in cellular development and differentiation, how the lineage fate of adult bone marrow progenitor cells (BMPCs) is reprogrammed during liver regeneration and whether this lineage switch is stably maintained are not clearly understood...

BACKGROUND: Management of ruptured arteriovenous malformations (AVMs) with a mass-producing intracerebral hematoma (ICH) represents a surgical dilemma. OBJECTIVE: To evaluate the clinical outcome and obliteration rates of microsurgical resection of AVM when performed concomitantly with evacuation of an associated space-occupying ICH. METHODS: Data of patients with AVM were collected prospectively. Cases were identified in which an AVM was resected and an associated space-occupying ICH was evacuated at the same time, and divided into "group 1," in which the surgery was performed acutely within 48 h of presentation (secondary to elevated intracranial pressure); and "group 2," in which selected patients were operated upon in the presence of a liquefying ICH in the "subacute" stage...

INTRODUCTION: Persistent or chronic intestinal ischemic injury (i3) can lead to severe malnutrition and acute mesenteric ischemia. Although recommended, revascularization of splanchnic arteries is sometimes unrealizable. MATERIAL AND METHODS: We report a case series of iloprost use in consecutive stable patients with persistent i3 unsuitable for revascularization followed in a tertiary care center. The feasibility of revascularization was discussed and ruled out by a multidisciplinary team, and informed consent was obtained prior to consideration of a vasoactive therapy...

We present the case of a 48-year-old woman with an acute type A aortic dissection that was treated with thoracic endovascular aortic repair at our institution. The patient was found to have a focal type A dissection with pericardial effusion but no tamponade physiology and no involvement of the aortic valve or root. We elected to treat the patient's type A aortic dissection with an endovascular stent because of the patient's favorable anatomy and no evidence of neurologic deficits or signs of distal malperfusion...

Astrocytes are the most abundant cell type of the central nervous system and cover a broad range of functionalities. We report here the generation of a novel monoclonal antibody, anti-astrocyte cell surface antigen-2 (Anti-ACSA-2). Flow cytometry, immunohistochemistry and immunocytochemistry revealed that Anti-ACSA-2 reacted specifically with a not yet identified glycosylated surface molecule of murine astrocytes at all developmental stages. It did not show any labeling of non-astroglial cells such as neurons, oligodendrocytes, NG2(+) cells, microglia, endothelial cells, leukocytes, or erythrocytes...

BACKGROUNDS/AIMS: To determine the importance of critical view of safety techniques in laparoscopic cholecystectomy. METHODS: A total of 120 patients were included in the study, between January 2015 to March 2016. Hydrodissection was performed for cases presenting with severe adhesions or cholecystitis. A critical view of safety was performed for all patients undergoing the procedure for isolation of cystic duct and cystic artery with cystic plate dissection. Demographic characteristics of the patients, as well as intraoperative and postoperative minor or major complications were recorded...

Acute aortic dissection is rare among young patients in the absence of connective tissue disorders. One of the risk factors associated with aortic dissection among young patients is amphetamine use. We report a case of a 37-year-old female with a past medical history of hypertension presenting with syncope and altered mental status who was found to have an acute DeBakey Type I aortic dissection after ingestion of 3,4-methylenedioxymethamphetamine (MDMA), commonly known as ecstasy. This is the second case in the literature describing aortic dissection in relation to MDMA use...

Background Emergency stent placement in the extracranial internal carotid artery in combination with anterior circulation thrombectomy is a routine procedure. Yet, precise indications and clinical safety in this setting remains controversial. Present data for mechanical thrombectomy include few studies with acute stenting of tandem occlusions. We evaluated the feasibility, safety and clinical outcome of this endovascular treatment in a retrospective analysis of all consecutive cases at a comprehensive stroke centre...

Leukocyte recruitment is an important process in combatting pathogens. The largest class of circulating leukocytes are neutrophils, which rapidly invade inflamed tissue, followed by inflammatory Ly6C(+) monocytes. Ly6C(low) monocytes patrol the endothelial wall routinely in the steady state. We recently reported early luminal recruitment of Ly6C(low) monocytes, which preceded and orchestrated neutrophil arrival and extravasation in response to TLR7/8-mediated vascular inflammation. Here we dissected the kinetics of recruitment of monocytes and neutrophils and examined the dynamics of Ly6C(low) monocytes in response to several other Toll-like receptor (TLR) agonists, using intravital confocal microscopy...

Gastric carcinoid tumor is rarely diagnosed in children. We report a case of gastric carcinoid tumor that occurred after allogeneic HSCT. A 13-year-old girl with ETP acute lymphoblastic leukemia underwent allogeneic HSCT from a 7/8 HLA-matched unrelated donor. She presented with rashes, abdominal pain, and diarrhea, which were suggestive of GVHD, 7 months after HSCT. Immunosuppressive agents failed to resolve these symptoms well. After a series of evaluations, carcinoid syndrome caused by a gastric carcinoid tumor was diagnosed...

OBJECTIVES: Surgery for acute type A aortic dissection (ATAD) carries a high risk of operative mortality. We examined the surgeon volume-outcome relation with respect to in-hospital mortality for patients presenting with this pathology in the United Kingdom. METHOD: Between April 2007 and March 2013, 1550 ATAD procedures were identified from the National Institute for Cardiovascular Outcomes Research database. A total of 249 responsible consultant cardiac surgeons from the United Kingdom recorded 1 or more of these procedures in their surgical activity over this period...

Aortic dissection is a life-threatening condition in which early diagnosis, treatment and close follow up are critical for survival. Between 60% and 70% of patients with acute aortic dissection are affected at the ascending aorta, classified as Stanford type A (TAD). Preventive surgery of the aorta in asymptomatic patients on the basis of aortic size alone remains controversial among patient populations without known risk factors for aortic dissection. In fact, many dissection patients do not appear to have markedly dilated aortas at the time of presentation...

Pulmonary thromboendarterectomy (PTE), also referred to as pulmonary endarterectomy, is the definitive treatment for chronic thromboembolic pulmonary hypertension (CTEPH). The true incidence of CTEPH is unknown and difficult to ascertain; however, most experts agree that approximately 4% to 5% of all patients who have an acute episode of pulmonary embolism (PE) will continue to develop CTEPH. Based on an incidence rate of about 0.1% for acute PE, this translates into a CTEPH incidence of approximately 10,000 to 15,000 annually in the United States alone...

Acute neuronal tissue preparations, brain slices and retinal wholemount, can usually only be maintained for 6 - 8 h following dissection. This limits the experimental time, and increases the number of animals that are utilized per study. This limitation specifically impacts protocols such as calcium imaging that require prolonged pre-incubation with bath-applied dyes. Exponential bacterial growth within 3 - 4 h after slicing is tightly correlated with a decrease in tissue health. This study describes a method for limiting the proliferation of bacteria in acute preparations to maintain viable neuronal tissue for prolonged periods of time (>24 h) without the need for antibiotics, sterile procedures, or tissue culture media containing growth factors...

Vagus nerve stimulation (VNS) has been reported to be effective in the abortive treatment of both migraine and cluster headache. Using validated animal models of acute dural-intracranial (migraine-like) and trigeminal-autonomic (cluster-like) head pain we tested whether VNS suppresses ongoing and nociceptive-evoked firing of trigeminocervical neurons to explain its abortive effects in migraine and cluster headache. Unilateral VNS was applied invasively via hook electrodes placed on the vagus nerve. A single dose of ipsilateral or contralateral VNS, to trigeminal recording and dural-stimulating side, suppressed ongoing spontaneous and noxious dural-evoked trigeminocervical neuronal firing...

Blunt cerebrovascular injury (BCVI) to the carotid artery is a relatively rare injury that is difficult to identify even with imaging. Any symptoms or neurological deficits following blunt neck injury mandate evaluation and consideration of BCVI. In an effort to highlight this issue, we report the case of a 31-year-old male patient who presented with left-sided weakness consistent with transient ischemic attack (TIA) and concussion. The patient's symptoms occurred within 24 hours of a blunt neck injury sustained by a knee strike during a basketball game...
