Periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis syndrome - PFAPA syndrome.

Periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) syndrome is a complex autoinflammatory disease with a clinical phenotype characterised by recurrent episodes of fever, systemic inflammation and symptoms and signs depicted in disease acronym. Although PFAPA is the most common autoinflammatory disease among children in many parts of the world, the condition is still an enigma, which include the regular episodes, the prompt responses to corticosteroids, the genetic bases for the familial clustering and therapeutic effects of tonsillectomy. This review explores PFAPA syndrome with the aim of describing the current clinical and scientific understanding of the condition.

[Familial Mediterranean fever – an important disease in a globalised world].

Familial Mediterranean fever - an important disease in a globalised world Familial Mediterranean fever (FMF) is characterized by recurrent febrile attacks during 1/2-3 days associated with peritonitis, pleuritis and arthritis. FMF is the most common monogenic autoinflammatory disease in the world, with over 100 000 affected individuals. It is particularly common in individuals with an origin in the eastern Mediterranean Basin, where the disease has a prevalence of 100-200 per 100 000.

Review of autoinflammatory diseases, with a special focus on periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis syndrome.

Unlabelled: There have been remarkable developments in the field of autoinflammatory diseases over the last 20 years. Research has led to definitions of new conditions, increased understanding of disease mechanisms and specific treatment. The polygenic autoinflammatory condition of periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis (PFAPA) is the most common autoinflammatory disorder among children in many parts of the world.

Survival of Anisakis simplex in arrowtooth flounder (Atheresthes stomia) during frozen storage.

Survival of naturally occurring larvae of Anisakis simplex in fresh arrowtooth flounder (Atheresthes stomia) was determined after storage for specified periods at four freezing temperatures. All larvae were killed by 96, 60, 12, and 9 h at temperatures of -15, -20, -30, and -40 degrees C, respectively. The average percentages of live larvae per fillet at the next shortest holding time were as follows: 72 h at -15 degrees C, 0 to 3%; 48 h at -20 degrees C, 11 to 30%; 9 h at -30 degrees C, 5%; and 6 h at -40 degrees C, 0 to 3%.

Survival of Anisakis simplex in microwave-processed arrowtooth flounder (Atheresthes stomias).

The purpose of this study was to define the relationship between survival and temperature of nematodes of the species Anisakis simplex in microwave-processed arrowtooth flounder (Atheresthes stomias). Ten fillets (each 126 to 467 g, 0.5 to 1.

Concentration and dispersal of a Pseudo-nitzschia bloom in Penn Cove, Washington, USA.

A bloom of the pennate diatom Pseudo-nitzschia, several species of which are associated with the production of the potent excitotoxin domoic acid, was observed in a Puget Sound, Washington embayment in July and August of 1997. Penn Cove, which receives nutrients from the nearby Skagit River and abundant sunshine during summer months due to its location in the rain shadow of the Olympic Mountains, is the home of a commercial mussel farm which supplies shellfish to many coastal areas of the USA. Levels of domoic acid in mussels increased to 3 ppm on 6 and 10 July, corresponding to the observation of a brown algal bloom in Penn Cove.

Template preparation for PCR and RFLP of amplification products for the detection and identification of Cyclospora sp. and Eimeria spp. Oocysts directly from raspberries.

Raspberries were epidemiologically associated with cyclosporiasis outbreaks during 1996 and 1997. The 18S rRNA genes of Cyclospora cayetanensis and several species of a closely related genus, Eimeria, were sequenced and primers for a nested PCR developed in a previous study. The ability to distinguish amplified products of Cyclospora sp.

[Children in poor countries also have right to good health care. A new care program will reduce child mortality].

According to the WHO (World Health Organization), 12 million children die annually before reaching the age of five. Seventy per cent of the deaths are related to one or more of five common diseases: acute respiratory tract infection, diarrhoea, measles, malaria and malnutrition. Consequently, drawing on international experience and expertise, the WHO and UNICEF (United Nations International Children's Emergency Fund) have compiled and developed guidelines for the primary care of Third World children.

Comparison of Template Preparation Methods from Foods for Amplification of Escherichia coli O157 Shiga-Like Toxins Type I and II DNA by Multiplex Polymerase Chain Reaction.

Escherichia coli O157:H7 has been responsible for several recent food-borne outbreaks in the United States. To protect the public health, it is essential that rapid and sensitive methods be developed for detection of this pathogen in foods. Methods were compared for preparation of template DNA for the polymerase chain reaction (PCR) from enrichments of food homogenates seeded with E.

Anisakid Parasites, Staphylococcus aureus and Bacillus cereus in Sushi and Sashimi from Seattle Area Restaurants.

Samples of salmon, tuna, mackerel, and rockfish sushi were analyzed for parasites from 32 of the approximately 50 restaurants in the Seattle area that prepare sushi. The restaurants were sampled up to three times over a 19-month period. Some specialty grocery stores providing restaurants and consumers with sashimi were also sampled.

Selective determination of histamine by flow injection analysis.

A flow injection analysis (FIA) method for the determination of histamine is described. Control of reaction timing allows exploitation of a transient, chemical-kinetic increase in selectivity that occurs when o-phthalaldehyde reacts with histamine. The molar fluorescence ratio (selectivity) of histamine/histidine reaches a maximum value of 800 in 32 s, precluding the need for separation of histamine from histidine, spermidine, and other potential interferences in biological samples.

Incidence of increased numbers of Clostridium perfringens in the intestinal tract of rats fed xylitol.

Sprague-Dawley rats were fed diets containing up to 20% xylitol for 49 days. When the rats were fed a xylitol regimen intended to produce adaptation to xylitol, approximately half of the animals adapted to xylitol and remained free from diarrhea during the feeding regimen. The other half did not adapt to xylitol and developed severe and persistent diarrhea accompanied by large volumes of intestinal gas.
