Urachal carcinoma is an extremely rare malignant tumor arising from the urachus in the fetus. We report a patient who developed urachal carcinoma 18 years after kidney transplantation. A 59-year-old man was admitted because of abdominal pain and massive ascites. He had undergone kidney transplantation 18 years earlier and had end-stage renal disease requiring dialysis. Abdominal CT showed massive ascites and an abdominal wall cystic mass separated from the peritoneal cavity. Hemodialysis was started, and paralytic ileus was diagnosed and treated...

Synaptic transmission is dynamic, plastic, and highly regulated. Drosophila is an advantageous model system for genetic and molecular studies of presynaptic and postsynaptic mechanisms and plasticity. Electrical recordings of synaptic responses represent a wide-spread approach to study neuronal signaling and synaptic transmission. We discuss experimental techniques that allow monitoring synaptic transmission in Drosophila neuromuscular and central systems. Recordings of synaptic potentials or currents at the larval neuromuscular junction (NMJ) are most common and provide numerous technical advantages due to robustness of the preparation, large and identifiable muscles, and synaptic boutons which can be readily visualized...

In the paralytic disease botulism, the botulinum neurotoxin (BoNT) passes through the bloodstream to reach and inactivate neuromuscular junctions. Monoclonal antibodies (mAbs) may be useful BoNT countermeasures, as mAb combinations can rapidly clear BoNT from the blood circulation. We have previously shown that the BoNT-neutralizing potency of mAbs can be improved through red blood cell (RBC) immunoadherence. For example, a fusion protein (FP) that adheres biotinylated mAbs to the RBC surface enabled a pair of mAbs to neutralize 5000 LD50 BoNT/A in the mouse protection assay...

Several marine microalgae produce dangerous toxins very damaging to human health, aquatic ecosystems and coastal resources. These Harmful Algal Blooms (HABs) in recent decades seem greatly increased regarding frequency, severity and biogeographical level, causing serious health risks as a consequence of the consumption of contaminated seafood. Toxins can cause various clinically described syndromes, characterised by a wide range of symptoms: amnesic (ASP), diarrhoetic (DSP), azaspirazid (AZP), neurotoxic (NSP) and paralytic (PSP) shellfish poisonings and ciguatera fish poisoning...

REVIEW
Philipp Hess
This paper presents a short summary of the knowledge on marine biotoxins. As toxins are known for their acute effects, they have been classified here according to the effects they cause in acute human poisoning incidents. Toxins may thus be distinguished into those that affect the nervous system (paralytic and other neurotoxins), memory (amnesic poisons), and the digestive system (diarrhetic toxins). Furthermore, newly emerging toxins, such as ciguatoxins or shark toxins, and factors that lead to the introduction of toxins in new areas, are presented...

The article discusses the effects of diosmin and hesperidin on capillary blood flow in patients with secondary Raynaud's syndrome (RS). Raynaud's syndrome a difficult problem of modern angiology, since in its development there is a large range of disorders of the capillary blood flow of the limbs. Currently, the main way of therapy in patients with secondary Raynaud's syndrome is the use of either calcium channel blockers (if angiospastic stage of the disease), or prostaglandins of group E1 (with tropho-paralytic stage of secondary RS)...

The diagnosis ileus is one of the most common indications for an emergency laparotomy. In 70% of the cases, the small intestine is affected, and in 30% it is the colorectum. While stuck hernias are a major cause in developing countries, the most common causes in western countries are postoperative adhesions that lead to an acute bowl obstruction. The timeframe for treatment of a complete mechanical obstruction is short as acute ischemia can lead to necrosis with bowl perforation within 6 h. The perioperative lethality for an emergency laparotomy due to an ileus ranges from 5-15%...

Saxitoxin (STX) is a potent marine toxin that causes paralytic shellfish poisoning (PSP) which can result in significant morbidity and mortality in humans. Low lethal doses, rapid onset of PSP symptoms, and brief STX half-life in vivo require sensitive and rapid diagnostic techniques to monitor human exposures. Our laboratory has validated an enzyme-linked immunosorbent assay (ELISA) for quantitative detection of STX from 0.020 to 0.80 ng/mL in human whole blood and from 0.06 to 2.0 ng/mL in dried human blood which is simple, sensitive, rapid, and cost-effective...

Irreversible electroporation (IRE) is a nonthermal ablation modality employed to induce in situ tissue-cell death. This study sought to evaluate the efficacy of a novel high-frequency IRE (H-FIRE) system to perform hepatic ablations across, or adjacent to, critical vascular and biliary structures. Using ultrasound guidance H-FIRE electrodes were placed across, or adjacent to, portal pedicels, hepatic veins, or the gall bladder in a porcine model. H-FIRE pulses were delivered (2250 V, 2-5-2 pulse configuration) in the absence of cardiac synchronization or intraoperative paralytics...

Following heavy precipitation, we observed an intense algal bloom in the St. Lawrence Estuary (SLE) that coincided with an unusually high mortality of several species of marine fish, birds and mammals, including species designated at risk. The algal species was identified as Alexandrium tamarense and was determined to contain a potent mixture of paralytic shellfish toxins (PST). Significant levels of PST were found in the liver and/or gastrointestinal contents of several carcasses tested as well as in live planktivorous fish, molluscs and plankton samples collected during the bloom...

Unraveling the genetics of the paralytic strabismus syndromes known as congenital cranial dysinnervation disorders (CCDDs) is both informing physicians and their patients and broadening our understanding of development of the ocular motor system. Genetic mutations underlying ocular CCDDs alter either motor neuron specification or motor nerve development, and highlight the importance of modulations of cell signaling, cytoskeletal transport, and microtubule dynamics for axon growth and guidance. Here we review recent advances in our understanding of two CCDDs, congenital fibrosis of the extraocular muscles (CFEOM) and Duane retraction syndrome (DRS), and discuss what they have taught us about mechanisms of axon guidance and selective vulnerability...

Management of constipation in patients receiving cyclophosphamide, doxorubicin, vincristine and prednisolone (CHOP) or CHOP-like chemotherapy regimens is important for prevention of paralytic ileus. We reported earlier that the laxative action of magnesium oxide is reversed by the concomitant use of antacids in cancer patients receiving opioid analgesics. Here, we assessed the prevalence of prophylactic laxative medication for the control of constipation in patients receiving CHOP or CHOP-like regimens for non-Hodgkin's lymphoma...

Botulinum neurotoxin (BoNT) produced by neurotoxigenic clostridia is the most potent biological toxin known and the causative agent of the paralytic disease botulism. The nutritional, environmental, and genetic regulation of BoNT synthesis, activation, stability, and toxin complex (TC) formation are not well studied. Previous studies indicated that growth and BoNT formation was affected by arginine and glucose in C. botulinum types A and B. In the present study, C. botulinum ATCC 3502 was grown in toxin production medium (TPM) with different levels of arginine, glucose and three products of arginine metabolism, citrulline, proline and ornithine...

Botulinum neurotoxins (BoNTs) and tetanus neurotoxin (TeNT) are the causative agents of the paralytic diseases botulism and tetanus, respectively. Entry of toxins into neurons is mediated through initial interactions with gangliosides, followed by binding to a protein co-receptor. Herein, we aimed to understand the mechanism through which individual neurotoxins recognize the carbohydrate motif of gangliosides. Using cell-based and in vitro binding assays, in conjunction with structure-driven site-directed mutagenesis, a conserved hydrophobic residue within the BoNTs that contributes to both affinity and specificity toward Sia5-containing gangliosides was identified...

In recent years, evidence has grown for the presence of tetrodotoxin (TTX) in bivalve mollusks, leading to the potential for consumers of contaminated products to be affected by Tetrodotoxin Shellfish Poisoning (TSP). A single-laboratory validation was conducted for the hydrophilic interaction LC (HILIC) tandem MS (MS/MS) analysis of TTX in common mussels and Pacific oysters-the bivalve species that have been found to contain TTXs in the United Kingdom in recent years. The method consists of a single-step dispersive extraction in 1% acetic acid, followed by a carbon SPE cleanup step before dilution and instrumental analysis...

BACKGROUND: Enteroviral infections can cause acute flaccid paralysis secondary to anterior myelitis. Magnetic resonance imaging (MRI) is important in the diagnosis of this potentially devastating pediatric disease. Before the 2014 outbreak of Enterovirus D68 (EV-D68), the virus was considered a relatively benign disease. CASE REPORT: A fully immunized 8-year-old boy was brought to the emergency department complaining of a cough, headache, neck pain, and right arm pain and weakness...
