Pneumonia associated with contact with cyanobacteria.

Abstract

aplastic anaemia is characterised by anaemia, leucopenia, and thrombocytopenia. The defect is cellular with an increased tendency to infection and bleeding.4 Although prejudicial to the success of skin grafting, it is not a contraindication provided deficiencies are corrected perioperatively, haemostasis is achieved before grafting, and the formation of haematoma is avoided afterwards.Each of these children had a chronic cutaneous manifestation ofa haematological or immunodeficiency disease. Healing was assumed to be abnormal because of a defect in either humoral or cellular defence mechanisms. This assumption delayed referral for surgery by some months in each case, but debridement followed by split skin grafting produced rapid healing.We thank Professor J M Chessels and Dr D A Atherton for their permission to report on patients under their care. Case 2-A 16 year old army recruit was admitted on the same date with a four day history of malaise, vomiting, sore throat, blistering around the mouth, dry cough, and pleuritic pain on the left side. He had also developed central abdominal pain. On examination he had a fever, with a temperature of 39 2°C. Respiratory examination disclosed signs of left basal consolidation, which was confirmed by chest radiography, and abdominal examination showed epigastric and umbilical tenderness and tenderness in the right iliac fossa, with rebound tenderness. He was treated with penicillin and erythromycin, and his temperature settled within 24 hours. The tenderness in his right iliac fossa persisted for three days; the presumptive diagnosis was mesenteric adenitis. He was discharged after one week.

The effect of risk perception on public preferences and willingness to pay for reductions in the health risks posed by toxic cyanobacterial blooms

“…These include dermatological (Pilotto et al, 2004;Stewart et al, 2006), respiratory (Turner et al, 1990) and gastro-intestinal effects (Teixeira et al, 1993) as well as acute liver failure (Carmichael et al, 2001). While the most frequently reported ill health effects comprise relatively minor hay fever-like symptoms, pruritic skin rashes and gastroenteritis, several case reports also document incidences of acute (Turner et al, 1990) and lethal toxicoses (Carmichael et al, 2001;Stewart et al, 2006)}.…”

Research has also linked cyanotoxins to clusters of primary liver cancer (Svircev et al, 2009) and as possible potentiators of neurodegenerative disease (Amyotrophic Lateral Sclerosis: Motor Neurone Disease) (Ince and Codd, 2005;Metcalf and Codd, 2009)}.…”

Mathematical modeling of Microcystis aeruginosa growth and [D-Leu1] microcystin-LR production in culture media at different temperatures

“…Its blooms are frequently found in eutrophic waters, affecting fish (Gaete et al, 1994), zooplankton communities (Amé et al, 2010), aquatic plants and vertebrates (MacKintosh et al, 1990). They are detrimental to water quality and negatively affect the development of nautical sports and other recreational activities (Turner et al, 1990;Giannuzzi et al, 2011). Many Microcystis strains can produce the potent hepatotoxin microcystin (MC), of which there are more than 100 variants, causing liver damage as well as nephrotoxicity (Milutinovic et al, 2003;Merel et al, 2013;Niedermeyer, 2013).…”

“…Toxic freshwater cyanobacteria are very common worldwide and have been responsible for animal (1)(2)(3)(4) and human intoxications (5)(6)(7). In Portugal, cyanobacteria have been reported to commonly occur in natural lakes, reservoirs and large slow flowing rivers since the early 30s (8)(9)(10)(11).…”
