Triad of death

Brande Brown, Levon Agdere, Cornelia Muntean, Karen David
BACKGROUND Allgrove syndrome, or triple "A" syndrome (3A syndrome), is a rare autosomal recessive syndrome with variable phenotype, and an estimated prevalence of 1 per 1,000,000 individuals. Patients usually display the triad of achalasia, alacrima, and adrenocorticotropin (ACTH) insensitive adrenal insufficiency, though the presentation is inconsistent. CASE REPORT Here, the authors report a case of Allgrove syndrome in a pediatric patient with delayed diagnosis in order to raise awareness of this potentially fatal disease as a differential diagnosis of alacrima...

Neuronal cell death in neurodegenerative diseases is not fully understood. Here we report that mutant huntingtin (Htt), a causative gene product of Huntington's diseases (HD) selectively induces a new form of necrotic cell death, in which endoplasmic reticulum (ER) enlarges and cell body asymmetrically balloons and finally ruptures. Pharmacological and genetic analyses revealed that the necrotic cell death is distinct from the RIP1/3 pathway-dependent necroptosis, but mediated by functional deficiency of TEAD/YAP-dependent transcription...

Multiple organ failure is a significant complication in traumatic injury, and can be exacerbated by a failure to adequately monitor and control trauma patients' core body temperature in emergency departments (EDs). Nearly half of trauma patients are hypothermic on arrival at emergency departments, often due to factors beyond the control of emergency service responders and during on-scene resuscitation attempts. This article examines the physiology of the 'triad of death' -hypothermia, metabolic acidosis and coagulopathy - to highlight the importance of monitoring and maintaining normothermia, or normal body temperature, which is between 36°C and 37...

: To effectively infect cells, Lassa virus needs to switch in endosomal compartment from its primary receptor α-dystroglycan to a protein termed LAMP1. A unique histidine triad on the surface of the receptor-binding domain from the glycoprotein spike complex of Lassa virus is important for LAMP1 binding. Here we investigate mutated spikes that have impaired ability to interact with LAMP1 and show that although LAMP1 is important for efficient infectivity it is not required for spike-mediated membrane fusion per se...

Prime-boost vaccination with recombinant (r) vaccinia(V)-CEA(6D)-TRICOM (triad of co-stimulatory molecules B7.1, ICAM-1 and LFA-3) and rFowlpox(F)-CEA(6D)-TRICOM infect antigen-presenting cells and direct expression of co-stimulatory molecules. We hypothesized that co-administration of vaccine with GM-CSF and interferon alpha (IFN-α) would have efficacy in CEA-expressing cancers. Patients with CEA-expressing cancers received the rV-CEA(6D)-TRICOM vaccine subcutaneously (s.c.) on day 1 followed by GM-CSF s...

INTRODUCTION: In the tropics, the triad of fever, thrombocytopenia, and AKI portends a grim prognosis with high mortality and a severe strain on already-stretched resources. Malaria, dengue, and leptospirosis account for most cases. We undertook a review of cases to determine factors accounting for adverse prognosis. METHODS: All patients presenting to the emergency room (ER) with a history of fever, thrombocytopenia, and renal failure were included in the study...

Plants protect themselves from pathogen attacks via several mechanisms, including hypersensitive cell death. Recognition of pathogen attack by the plant resistance gene triggers expression of carboxylesterase genes associated with hypersensitive response. We identified six transcripts of carboxylesterase genes, Vitis flexuosa carboxylesterase 5585 (VfCXE5585), VfCXE12827, VfCXE13132, VfCXE17159, VfCXE18231, and VfCXE47674, which showed different expression patterns upon transcriptome analysis of V. flexuosa inoculated with Elsinoe ampelina...

Huntington's disease (HD) is an autosomal dominant neurodegenerative disease characterized by a triad of progressive motor dysfunction, cognitive decline and psychiatric disturbances. The hallmark of HD is the distinctive choreiform movement disorder that typically has a subtle, insidious onset in the fourth to fifth decade of life and gradually worsens over 10 to 20 years until death. Notably, two-thirds of HD patients present with chorea and one third with mental changes. The prevalence of psychiatric symptoms is significantly higher than in the general population, and is estimated to be around 66-73%...

OBJECTIVE: Sporadic Creutzfeldt-Jakob disease (CJD) is a human prion disease, rapidly progressive and fatal, characterized by spongiform encephalopathy. The characteristic triad of signs - rapidly progressive dementia, myoclonus and periodic sharp wave complexes (PSWC) on electroencephalography (EEG) - usually appear in the late stages of the disease. The clinical diagnosis of CJD ante-mortem involves the exclusion of the rapidly progressive non-prionic dementias, the definitive diagnosis requiring brain tissue confirmation...

BACKGROUND: Hemolytic-uremic syndrome (HUS) is a clinical triad of microangiopathic hemolytic anemia, impaired renal function and thrombocytopenia, primarily affecting pre-school-aged children. HUS can be classified into diarrhea-associated HUS (D(+)HUS), usually caused by Shiga toxin-producing Escherichia coli (STEC), and non-diarrhea-associated HUS (D(-)HUS), both with potentially serious acute and long-term complications. Few data exists on the clinical features and long-term outcome of HUS in Norway...

OBJECTIVE: We created a system using a triad of change management, electronic surveillance, and algorithms to detect sepsis and deliver highly sensitive and specific decision support to the point of care using a mobile application. The investigators hypothesized that this system would result in a reduction in sepsis mortality. METHODS: A before-and-after model was used to study the impact of the interventions on sepsis-related mortality. All patients admitted to the study units were screened per the Institute for Healthcare Improvement Surviving Sepsis Guidelines using real-time electronic surveillance...

Squamous cell carcinomas (SCC) arising in upper parts of the aerodigestive tract are among the leading causes of death worldwide. EGFR has been found to play an essential role in driving the malignancy of SCC of the upper aerodigestive tract (SCCUAT), but, despite this, clinical results using a range of different EGFR-targeted agents have been disappointing. Cetuximab is currently the only EGFR-targeted agent approved by the FDA for treatment of SCCUAT. However, intrinsic and acquired cetuximab resistance is a major problem for effective therapy...

BACKGROUND: An abdominal aortic aneurysm (AAA) is the pathological enlargement of the aorta and can develop in both men and women. Progressive aneurysm enlargement can lead to rupture. The rupture of an AAA is frequently fatal and accounts for the death from haemorrhagic shock of at least 45 people per 100,000 population. The outcome of people with ruptured AAA varies among countries and healthcare systems, with mortality ranging from 53% to 90%. Definitive treatment for ruptured AAA includes open surgery or endovascular repair...

Burkholderia cenocepacia is an opportunistic pathogen of the cystic fibrosis lung that elicits a strong inflammatory response. B. cenocepacia employs a type VI secretion system (T6SS) to survive in macrophages by disarming Rho-type GTPases, causing actin cytoskeletal defects. Here, we identified TecA, a non-VgrG T6SS effector responsible for actin disruption. TecA and other bacterial homologs bear a cysteine protease-like catalytic triad, which inactivates Rho GTPases by deamidating a conserved asparagine in the GTPase switch-I region...

In this study, we identify signaling network of necrotic cell death induced by transcriptional repression (TRIAD) by α-amanitin (AMA), the selective RNA polymerase II inhibitor, as a model of neurodegenerative cell death. We performed genetic screen of a knockdown (KD) fly library by measuring the ratio of transformation from pupa to larva (PL ratio) under TRIAD, and selected the cell death-promoting genes. Systems biology analysis of the positive genes mapped on protein-protein interaction databases predicted the signaling network of TRIAD and the core pathway including heterogeneous nuclear ribonucleoproteins (hnRNPs) and huntingtin (Htt)...

Child abuse or nonaccidental trauma is a major problem worldwide; in Spain, there are about 12,000 victims per year. The detection of specific lesions or findings that are incongruent with the reported mechanism of trauma mean that radiologists are often the physician responsible for sounding the alarm in cases of abuse. The triad consisting of subdural hematoma, metaphyseal fracture, and posterior rib fractures is very characteristic of the battered child syndrome. The finding of acute and chronic lesions in the same patient is highly specific for nonaccidental trauma...

Dengue virus is a major issue of tropical and sub-tropical regions. Dengue virus has been the cause behind the major alarming epidemics in the history with mass causalities from the decades. Unavailability of on-shelf drugs for the prevention of further proliferation of virus inside the human body results in immense number of deaths each year. This issue necessitates the design of novel anti-dengue drug. The protease enzyme pathway is the critical target for drug design due to its significance in the replication, survival and other cellular activities of dengue virus...
