Non-invasive and rapid diagnosis of type 2 diabetes mellitus based on the analysis of hair by front-face fluorescence spectroscopy.

Rapid and early detection of pathologies for screening purposes is not always easy with traditional methods. New low-cost optical techniques that are suitable for preventive detection and, more specifically, for developing countries must be developed. The objective of this work is to propose UV-VIS fluorescence of hair as a promising technique for a simple and rapid preliminary diagnosis of type II diabetes.

Fast diagnostic of osteoporosis based on hair analysis using LIBS technique.

Currently, the reference method for the diagnose of the osteoporosis pathology is the Dual energy X-ray Absorptiometry (DXA) technique which assesses Bone Mineral Density (BMD). As a major public health problem, classified as such by the World Health Organization, it is necessary to develop new techniques that are more accessible, especially for developing countries. The objective of this work is to propose a new technique based on laser-induced breakdown spectroscopy (LIBS) using calcium and sodium in hair as a biomarker for the detection of osteoporosis pathology.

[The role of piezosurgery in the treatment of a rare case of superinfected cemento-osseous dysplasia caused by actinomyces: a case report].

Cemento-osseous dysplasia is a benign fibro-osseous lesion affecting the alveolar bone. It is classified into three forms: periapical, focal or florid dysplasia. It is often asymptomatic and fortuitously discovered during a routine radiological examination.

Simple and fast diagnosis of osteoporosis based on UV-visible hair fluorescence spectroscopy.

The aim of this work is to propose a new analytical technique based on UV-visible fluorescence as an alternative to x-ray absorptiometry for diagnosing osteoporosis, as well as its early stage by identifying osteopenia. The equipment used consists of very cheap equipment compared to x-ray scanners with an LED as the excitation source. In this work, we analyzed 90 hair samples taken from volunteers of different ages at Habib Thameur Hospital in Tunis.

Muscular hypotonia as an onset manifestation of Tuberculosis meningitis in an HIV-negative patient.

Muscular hypotonia is considered as one of the rarest forms of initial onset signs of TBM, in addition to aphasia and hyponatremia, the awareness of those rare onset signs, a well-conducted diagnostic approach and early treatment can improve the outcome.

Expression profile of biomarkers altered in papillary and anaplastic thyroid carcinoma: Contribution of Tunisian patients.

Aims: The objective of this study was to compare the protein expression profile between well-differentiated (papillary) and undifferentiated (anaplastic) thyroid carcinoma in Tunisian patients.

Methods: This first Tunisian retrospective study concerned data of 38 thyroid cancer cases (19 papillary carcinoma PTC and 19 anaplastic carcinoma ATC) collected at Salah Azaiez Institute of Tunisia. Immunohistochemistry was used to evaluate tumor expression of different molecular markers (p53, Ki67, E-cadherin, cyclin D1, bcl2, S100 and Her-2).
