Abstract A male child born at 27 weeks, weighting 1305 g and presenting with a right-sided abdominal tumor. Computed tomography scan demonstrated the presence of a solid mass compressing the right kidney. Puncture biopsy revealed congenital mesoblastic nephroma. The patient underwent total right nephroureterectomy, and died on the second day after surgery.

INTRODUCTION: The main clinical manifestations of Whipple's disease are weight loss, arthropathy, diarrhea and abdominal pain. Cardiac involvement is frequently described. However, endocarditis is rare and is not usually the initial presentation of the disease. To the best of our knowledge, this is the first reported case of a patient with Tropheryma whipplei tricuspid endocarditis without any other valve involved and not presenting signs of arthralgia and abdominal involvement. CASE PRESENTATION: We report a case of a 50-year-old Caucasian man with tricuspid endocarditis caused by Tropheryma whipplei, showing signs of severe shock and an absence of other more classic clinical signs of Whipple's disease, such as arthralgia, abdominal pain and diarrhea. Tropheryma whipplei was documented by polymerase chain reaction of the blood and pleural fluid. The infection was treated with a combined treatment of doxycycline, hydroxychloroquine and sulfamethoxazole-trimethoprim for one year. CONCLUSION: Tropheryma whipplei infectious endocarditis should always be considered when facing a blood-culture negative endocarditis particularly in right-sided valves. Although not standardized yet, treatment of Tropheryma whipplei endocarditis should probably include a bactericidal antibiotic (such as doxycycline) and should be given over a prolonged period of time (a minimum of one year).

Infectious diseases in wild animals have been increasing as a result of their habitat alterations and closer contact with domestic animals. Canine distemper virus (CDV) has been reported in several species of wild carnivores, presenting a threat to wildlife conservation. We described the first case of canine distemper virus infection in lesser grison (Galictis cuja). A free-ranging individual, with no visible clinical sigs, presented sudden death after one day in captivity. Molecular diagnosis for CDV infection was performed using whole blood collected by postmortem intracardiac puncture, which resulted positive. The virus phylogeny indicated that domestic dogs were the probable source of infection.

Griscelli syndrome (GS) is a rare autosomal recessive disorder caused by mutation in the MYO5A (GS1, Elejalde), RAB27A (GS2) or MLPH (GS3) genes. Typical features of all three subtypes of this disease include pigmentary dilution of the hair and skin and silvery-gray hair. Whereas the GS3 phenotype is restricted to the pigmentation dysfunction, GS1 patients also show primary neurological impairment and GS2 patients have severe immunological deficiencies that lead to recurrent infections and hemophagocytic syndrome. We report here the diagnosis of GS2 in 3-year-old twin siblings, with silvery-gray hair, immunodeficiency, hepatosplenomegaly and secondary severe neurological symptoms that culminated in multiple organ failure and death. Light microscopy examination of the hair showed large, irregular clumps of pigments characteristic of GS. A homozygous nonsense mutation, C-T transition (c.550C>T), in the coding region of the RAB27A gene, which leads to a premature stop codon and prediction of a truncated protein (R184X), was found. In patient mononuclear cells, RAB27A mRNA levels were the same as in cells from the parents, but no protein was detected. In addition to the case report, we also present an updated summary on the exon/intron organization of the human RAB27A gene, a literature review of GS2 cases, and a complete list of the human mutations currently reported in this gene. Finally, we propose a flow chart to guide the early diagnosis of the GS subtypes and Chédiak-Higashi syndrome.

The article discusses the present status of weblogs and examines whether legal standards applicable to traditional press and media should be applied to that specific forum. The analysis is based on two key documents: the Draft Report on the concentration and pluralism in the media in European Union (2007/2253(INI)) of the European Parliament Committee on Culture and Education presented in March 2008 and a landmark decision of the Polish Supreme Court from July 26, 2007 (IV KK 174/07) in the light of present judicial tendency in other European countries. The first of the mentioned documents calls for the “clarification of the legal status of different categories of weblog authors and publishers as well as disclosure of interests and voluntary labelling of weblogs”. It emphasizes that the “undetermined and unindicated status of authors and publishers of weblogs causes uncertainties regarding impartiality, reliability, source protection, applicability of ethical codes and the assignment of liability in the event of lawsuits”. The position of the European Parliament, expressed in the document, raises serious questions on the limits of freedom of thought and speech on the Internet and on the degree of acceptable state control. A recent Polish Supreme Court decision, which caused quite a stir in the Polish Internet community, seems to head in the very direction recommended by the EP Culture Committee. In a case of two editors of a web journal (“czasopismo internetowe”) called “Szyciepoprzemysku”, available on-line, accused of publishing a journal without the proper registration, the Polish Supreme Court stated that “journals and periodicals do not lose the character of a press release due solely to the fact that they appear in the form of an  Internet transmission”, and that ‘’the publishing of press in an electronic form, available on the Internet, requires  registration”. The decision was most surprising, as prior lower courts decisions declined the possibility to register Internet periodicals. The accused were acquitted in the name of the constitutional principle of the rule of law (art. 7 of the Polish Constitution) and the ensuing obligation to protect the trust of a citizen to the state (a conviction in this case would break the collateral estoppel rule), however the decision quickly awoke media frenzy and raised the fear of a need to register all websites that were regularly updated. The spokesman of the Polish Supreme Court later explained that the sentence of the Court was not intended to cause a mass registration of all Internet “periodicals” and that neither weblogs nor Internet sites, that were regularly updated, needed registration. Such an interpretation of the Polish press law did not appear clear based only on the original text of the judgment and the decision as such still raises serious practical questions. The article aims to examine the status of Internet logs as press and seeks the compromise between the concerns expressed by European authorities and the freedom of thought and speech exercised on the Internet.

One thousand, two hundred and sixty four samples of individually quick-frozen (IQF) peeled and deveined raw and 914 samples of cooked ready to eat shrimp samples produced from farm raised black tiger (Penaeus monodon) obtained from a seafood unit working under HACCP concept were analysed for total aerobic plate count (APC), coliform count, Escherichia coli, coagulase positive Staphylococci and Salmonella. The overall bacteriological quality of the product was found to be good. Of the frozen raw shrimp, 96% of samples showed APC below 105 while 99% of the frozen cooked ready-to-eat samples showed APC less than 104. The APC ranged from 1·0´102 to 4·2´106 cfu/gm in frozen raw shrimp and from 1·0´102 to 6·4´104 cfu/gm in the frozen cooked shrimp. Prevalences of coliforms in raw shrimp and cooked shrimp samples were 14·4% and 2·9% respectively. The coliform count in raw products ranged from 1·0´101 to 2·5´103 cfu/gm and in the cooked products, from 1·0 ´101 to 1·8´102 cfu/gm. Although all the cooked shrimp samples were free of coagulase positive staphylococci, E. coli and Salmonella, 1·0, 2·0 and 0·1% of the frozen raw shrimp samples tested positive for coagulase positive Staphylococci, E. coli and Salmonella respectively. The Salmonella strain was identified as Salmonella typhimurium. The results of the present study highlight the importance of implementation of HACCP system in the seafood industry to ensure consistent quality of frozen seafood
