We report a 40-year-old man with end-stage renal disease due to IgA nephropathy who underwent deceased donor kidney transplantation. The donor was diagnosed to be brain-dead due to cerebral hemorrhage after her second liver transplantation for non-viral liver cirrhosis. Intraoperative 1-hour biopsy of the graft kidney revealed moderate global glomerular sclerosis (22%) and interstitial fibrosis (40%) consistent with underlying nephrosclerosis or calcineurin inhibitor nephrotoxicity. Although hemodialysis was needed until the graft began functioning several days after the kidney transplantation, the postoperative clinical course thereafter was uneventful and the graft functioned well with stable serum creatinine levels around 2...

Inflammatory responses and innate immunologic reactions play an important role in the respiratory system. Ex vivo lung perfusion (EVLP) is considered a novel method in the evaluation and reconditioning of donor lungs prior to transplantation. However, EVLP's effect on inflammatory and metabolic markers of human lung tissue is unknown.  This study investigated how the performance of EVLP on brain-dead (BD) donor lungs affects the production and release of inflammatory cytokines (IL-6, IL-8, and TNF-a), inflammatory cells and toll-like receptors (TLR) -2, 4...

BACKGROUND: After a severe shortage of brain-dead donors, the demand for heart transplantation has never been greater. In an attempt to increase organ supply, abdominal and lung transplant programs have turned to the donation after circulatory-determined death (DCD) donor. However, because heart function cannot be assessed after circulatory death, DCD heart transplantation was deemed high risk and never adopted routinely. We report a novel method of functional assessment of the DCD heart resulting in a successful clinical program...

Panayiotis N Varelas, Ariane Lewis
People die either when their heart and respiration stop or when their brain irreversibly stops functioning. This latter mode of death by neurologic criteria (also called brain death) emerged after the development of ventilators and intensive care units in the late 1950s and 1960s. Brain death is universally accepted as a modern entity, but the complex process for declaring a patient brain dead is not uniformly followed across country and state lines or even hospital policies, creating unacceptable variability and risks for falsely pronouncing a patient dead...

The structure of the post-mortem human brain can be preserved by immersing the organ within a fixative solution. Once the brain is perfused, cellular and histological features are maintained over extended periods of time. However, functions of the human brain are not assumed to be preserved beyond death and subsequent chemical fixation. Here we present a series of experiments which, together, refute this assumption. Instead, we suggest that chemical preservation of brain structure results in some retained functional capacity...

Apoptosis is a widespread phenomenon that occurs in the brain in both physiological and pathological conditions. Dead cells must be quickly removed to avoid the further toxic effects they exert in the parenchyma, a process executed by microglia, the brain professional phagocytes. Although phagocytosis is critical to maintain tissue homeostasis, it has long been either overlooked or indirectly assessed based on microglial morphology, expression of classical activation markers, or engulfment of artificial phagocytic targets in vitro...

The objective of the present study was to examine the virulence of Toxoplasma gondii RH strain tachyzoites in embryonated eggs after continuous passage in Vero cell line. The first T. gondii tachyzoites was considered low passage (no passage) and then passaged for 80 times on Vero as high passage. Groups of 9-day-old embryonated eggs with ten eggs in each group were inoculated with 10(2),10(3) and 10(4) of low or high-passage T. gondii tachyzoites, and any mortality was recorded. Suitable samples from different tissues (liver, heart, and brain) of the dead embryos were collected for histopathological study...

INSTRUCTION: Inferior vena cava (IVC) thrombosis can be a life-threatening complication after liver transplantation (LT). Although this complication is usually related to technical problems associated with vascular anastomosis, we report a case of IVC thrombosis which developed from a ligated large mesenteric-caval shunt. PRESENTATION OF CASE: A 35-year-old man underwent LT from a brain-dead donor for primary sclerosing cholangitis. Enhanced computed tomography (CT) before LT showed a huge collateral vessel of the inferior mesenteric vein (IMV) draining into the infra-renal IVC directly...

Snakebite is an important medical problem in Sri Lanka. Of the deadly venomous snakes, Russell's viper (Daboia russelii) is widely distributed and responsible for most of the fatalities of snakebite in the country. It is not uncommon to see atypical manifestations in Russell's viper bite. We report the events of intracranial haemorrhages and multiple ischemic brain infarcts following Russell's viper (Daboia russelii) bite of a previously healthy 43-years-old male who succumbed to envenoming.

OBJECTIVES: Deep brain stimulation (DBS) is a form of biotechnological surgery which has had considerable success for the motor improvement of Parkinson's disease and related disorders. Paradoxically, this observed motor improvement is not matched with improved psychosocial adjustment. This study contributes to a small but growing body of research aiming to understand this paradox. We conclude by discussing these aspects from a phenomenological and health psychology understanding of decision-making, human affectivity, and embodiment...

BACKGROUND The characteristics of liver donors have changed over the last decade owing to the shortage of organs and high mortality on the waiting list, leading to wider use of extended-criteria donors, including older donors. The aim of this study was to evaluate the effect of matching donor-recipient age on morbidity at 1 year post-transplant and on long-term patient and graft survival. MATERIAL AND METHODS Retrospective study from a prospectively-obtained database including adult patients who had received a primary liver transplant (LT) from whole graft of brain-dead donors...

The "brain death" standard as a criterion of death is closely associated with the need for transplantable organs from heart-beating donors. Are all of these potential donors really dead, or does the documented evidence of patients destined for organ harvesting who improve, or even recover to live normal lives, call into question the premise underlying "brain death"? The aim of this paper is to re-examine the notion of "brain death," especially its clinical test-criteria, in light of a broad framework, including medical knowledge in the field of neuro-intensive care and the traditional ethics of the medical profession...

: In recent years, there has been increasing evidence that the totally brain-dead patient is able to continue to live and to maintain some integrated functions, albeit with the necessary assistance of mechanical ventilation. Several years ago, the autopsy report of a totally brain-dead patient named TK who was kept on life support for nearly twenty years was published in the Journal of Child Neurology. He remains the individual kept on life support the longest after suffering total brain failure...

As the Japanese organ donor allocation system does not permit the allocation of lungs at a priority level to patients on extracorporeal membrane oxygenation (ECMO), many of these patients die before suitable donor lungs become available. We report our first experience with ECMO as a bridge to lung transplantation (LTx) from a brain-dead donor. A 40-year-old man with interstitial lung disease who was listed for LTx 3 years previously, experienced progressive deterioration of respiratory function. He was mechanically ventilated at another hospital and was transported to our hospital due to severe hypoxemia...

During a series of epizootics caused by Yellow fever virus in Brazil between 2007 and 2009, a monkey was found dead (May 2009) in a sylvatic area in the State of Paraná. Brain samples from this animal were used for immunohistochemical analysis and isolation of a wild-type strain of YFV. This viral strain was characterized, and sequence analyzes demonstrated that it is closely related with YFV strains of the recently identified subclade 1E of the South American genotype I. Further characterization included indirect-immunofluorescence of different infected cell lines and analysis of the kinetics of virus replication and infectivity inhibition by type I IFN...

CONTEXT: Pancreatic duct glands (PDGs) have been proposed as a source of regeneration in response to exocrine pancreas injury, and thus may serve as an organ stem cell niche. There is evidence to suggest ongoing beta-cell formation in longstanding type 1 diabetes (T1D), but the source is unknown. OBJECTIVE: To investigate the pancreatic duct gland (PDG) compartment of the pancreas in humans with T1D for evidence of an active regenerative signature (presence of progenitor cells and increased proliferation) and, in particular, as a potential source of beta-cells...

Background A decrease in fatty acid amide hydrolase (FAAH) activity increases the levels of endogenous analogues of cannabinoids, or endocannabinoids. FAAH inhibitors have shown analgesic and antiinflammatory activity in animal models, and some have been tested in phase 1 and 2 studies. In a phase 1 study, BIA 10-2474, an orally administered reversible FAAH inhibitor, was given to healthy volunteers to assess safety. Methods Single doses (0.25 to 100 mg) and repeated oral doses (2.5 to 20 mg for 10 days) of BIA 10-2474 had been administered to 84 healthy volunteers in sequential cohorts; no severe adverse events had been reported...
