    Open-pollinated varieties (OPVs), such as beans, sorghum, and groundnuts, are important for increased income, job creation, food security, and nutrition of both urban and rural households in sub-Saharan Africa (SSA). However, the main constraint is underdeveloped seed systems, which contribute substantially to dwindling productivity among small-scale farmers due to limited access to reliable and quality planting materials. ACCELERATE is expected to accelerate varietal adoption and turnover in Tanzania by tapping into the power of large/small-scale or marketplace traders, and institutional seed buyers

    The authors present the first description of the electronmicroscopic appearance of eye lesions in a case of juvenile metachromatic leukodystrophy. They find the specific prismatic inclusions of sulfatidose in the ciliary nerves. They show other structures probably resulting from transformation of the myeline constituents in the optic and ciliary nerves. They insist on the absence of retinal lesions, although these have been described by most authors in the infantile form. (23 references)SCOPUS: NotDefined.jinfo:eu-repo/semantics/publishe

    A man who had suffered from celiac disease since infancy had been treated by a nonspecific diet during childhood, and for some years as an adult by a gluten free diet. At the age of 31 yr, laparotomy was performed for abdominal pains, with diarrhea and radiologically demonstrated duodenal stasis. No tumor was observed and a duodeno jejunostomy was performed. One yr later, the abdominal symptoms, recurred, and a jejunal biopsy now demonstrated severe atrophy of the mucosa. One mth later, an acute abdominal upset led to a 2nd laparotomy, which showed several tumors in the jejunum, with perforations. Histologic study demonstrated reticulosarcomas. Less than one yr later, the patient died from cachexra. The autopsy showed peritoneal tumors, adhering to the spleen, colon and stomach, gastric perforations communicating with the large intestine and a cavity bounded by the liver, diaphragm and abdominal wall. The histology of the tumor was identical with that seen at biopsy. The liver contained multiple hemangiomas. While many cases of the association of malabsorption syndromes with intestinal tumors have been reported, there are less than 40 cases of celiac disease of long duration in which, as a late complication, intestinal tumors developed. The lympho or reticulosarcomas were located on the proximal part of the jejunum, where the mucosal atrophy is most severe. The pathogenetic relations between intestinal atrophy and sarcoma formation are briefly discussed. (31 references)SCOPUS: ar.jinfo:eu-repo/semantics/publishe

    A case of tertiary hepatic syphilis is reported, allowing the authors to remind the rarity of this disease, though very anciently known, its poorly specific symptomatology, the necessity of a laparoscopic bioptic diagnosis, the debated response on the classical medical treatment and the probable absence of complications, other than portal hypertension. © 1983 Springer-Verlag.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

    La tumeur de grawitz chez l'enfant

    A Grawitz tumor was discovered in a five year old boy. Nephrectomy was performed. The child died four years later from generalized metastases. The clinical picture consisted mainly of a hematuria; radiographs disclosed a calcified tumor at the lower pole of the right kidney. The diagnosis was substantiated by histopathology; the autposy findings are described. Hypernephroma was thought to be very rare or non existent in childhood; however, 25 years ago, a few observations were made. In 1975, the literature quoted around 90 cases. The different features of Grawitz tumor in children, including clinical and histological aspects, are reviewed.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
