Multimodality imaging of thyroid-like follicular renal cell carcinoma with lung metastases, a new emerging tumor entity.

The International Society of Urological Pathology recently proposed classifying thyroid-like follicular renal cell carcinoma (TLF-RCC) as an emerging entity in renal epithelial tumors. Their entire proposal will be the framework for the next World Health Organization classification of renal tumors. Fewer than 15 cases of TLF-RCC have been reported in the literature up to date. We describe the multimodality imaging features of a patient with TLF-RCC. To our knowledge, this is the first case report in the literature commenting on the multimodality imaging appearance of this tumor.

[Yellow fever epidemic in the extreme North of Cameroon in 1990: first yellow fever virus isolation in Cameroon]. / L'épidémie de fièvre jaune de l'extrême nord du Cameroun en 1990: premier isolement du virus amaril au Cameroun.

Some two years ago, suspicious cases of yellow fever (YF) were reported in northern Cameroon. A deadly epidemic broke out during the second half of the rainy season (from 15 September to 22 December 1990) with 180 known cases, of which 125 died. The real figures could have been between 5000 and 20,000 cases with between 500 and 1000 deaths. The affected area was within the yellow fever belt, which is situated around latitude 11 degrees North and 14 degrees East. In this mountainous area (altitude, about 800 m) the rural inhabitants are scattered, with a high density of 200,000 people per 1000 km2. Investigations began at the start of the dry season and a strain of yellow fever virus was isolated for the first time in Cameroon. A study of 107 serum samples (23 families in 11 villages) was carried out by immunofluorescence and ELISA, which showed 20% IgM carriers for yellow fever virus and nothing for the three other flaviviruses, although these were largely present; there were up to 98% crossed reactions in IgG with dengue 2 and West Nile strains. The under-10 age group represented 63% of the IgM carriers. An entomological study was carried out at the same time. It permitted the capture of Aedes aegypti, A. furcifer, A. luteocephalus and the identification of numerous potential larval sites, at times still in the productive phase of A. aegypti which is considered to be the principal vector.(ABSTRACT TRUNCATED AT 250 WORDS)

[The combined measles-yellow fever vaccination in African infants aged 6 to 10 months]. / Etude de la vaccination combinée rougeole-fièvre jaune chez l'enfant African âgé de 6 à 10 mois.

The compared tolerance and immunogenicity of vaccines against yellow fever and measles, separately administered or combined, have been evaluated in a group of 319 children from North Cameroon, aged 6-10 months. The clinical tolerance was excellent for both the isolated and the combined vaccines. The seroconversion level is higher after administration of the combined vaccine: 89.9% against 83.5% for measles, 95.8% against 92.6% for yellow fever, but these results are not significantly different. 30 days after vaccination, the antibody titers are higher with the combined vaccine: 215.3 against 156.5 for measles (non significant difference), 34 against 22.6 for yellow fever (highly significant difference). Whatever the vaccination method is, the antibody levels are protecting. It becomes then possible to include the combined vaccination against yellow fever and measles in the EPI of yellow fever endemic countries.

[Isolation of Kluyvera ascorbata from Madagascan lemurs, healthy carriers of this unusual enterobacterium]. / Isolement de Kluyvera ascorbata chez des lémuriens malgaches, porteurs sains de cette entérobactérie inhabituelle.

Six strains of Kluyvera ascorbata--an unusual species in the family Enterobacteriaceae--were isolated from six healthy lemurs, located in Tananarive's zoological garden. Their bacteriological characters are reported and compared with those of Levinea and Escherichia coli. Their occurrence and significance in animals are discussed.

[A reservoir of Shigella of avian origin: herons and birds of prey of the zoological garden in Tananarive]. / Un réservoir de Shigella d'origine aviaire: les hérons et rapace du jardin zoologique de Tananarive.

The authors record the bacteriological characters of four Shigella strains: S. dysenteriae 2 and S. boydii 9, respectively isolated in a bird-of-prey and in three herons, kept in the zoological Garden in Antananarivo. The significance of this Malgasian avian reservoir of Shigella is discussed.

Normal pregnancy and delivery after cerebral metastases of choriocarcinoma: Case report.

Normal pregnancy and delivery after chemotherapy and radiation of cerebral metastases in a case of choriocarcinoma is presented. The need of surgical approach to these lesions as proposed by Stilp and his group is questioned.
