The capillary changes at the initial stage of diabetes may show an angioarchitecture clearly different from those of later stages and/or very severe glomerular change. However, the onset of alterations in the early phases is unclear. This study attempts to determine the structural alterations of the glomerular wall and vessels in the early stage of diabetes. ⋯ In early stages of diabetes mellitus in rats, there was an increase in the diameter of glomerular vessels. In later stages of the disease, the reverse was seen, but insulin treatment had a positive role in reversing these changes in the study subjects.

Medical research and publications are the back-bone for advancing the medical field. We identified the Pubmed medical publications that are affiliated with Libya to shed some light on the contribution of this country's medical community to the PubMed database. All publications affiliated with Libya in the PubMed were counted over a five year period ending December 2006. We also used the same method to obtain data on the PubMed medical publications from Tunisia, Morocco and Yemen. Tunisia had the largest number of PubMed publications among the studied countries: 20.4 publications per million population per year and 7.2 publications per year per one billion US$ GDP. Libya had much fewer publications: 2.4 publications per million population per year and 0.4 publications per one billion US$ GDP. The citation frequency for Libyan published research was very low compared to Tunisian and Moroccan related research. ⋯ This preliminary analysis shows that medical research output in Libya is about twenty times less than in other countries with similar backgrounds, and that it needs to be enhanced.

Cemento-ossifying fibroma occurring in an elderly patient. A case report and a review of literature.
Cemento-ossifying fibromas (COF) are benign lesions affecting the jaws and other craniofacial bones. They commonly affect adults between the third and fourth decade of life. Radiographically, they appear as well-defined unilocular or multilocular intraosseous masses, commonly in the premolar/molar region of the mandible. ⋯ The patient continued to be asymptomatic with minimum changes. Occurrence of cemento-ossifying fibroma in patients over 60 years of age is unusual and had not been reported. The clinical, radiographic, histopathology and literature review are discussed.
