Brucellosis is an intracellular bacterial infection contracted by consuming raw milk or by contact with infected cattle. Neurobrucellosis is a rather rare manifestation of brucellosis and has protean clinical presentations characterized by meningoencephalitis, myelitis, myelopathies, subarachnoid hemorrhage and psychiatric manifestations. A depressed immune status is believed to be a risk factor for developing neurobrucellosis. We report a case of neurobrucellosis in a patient 13 years after a cadaveric renal transplantation. Even though a Brucella organism was not isolated from body fluids she satisfied other criteria for establishing the diagnosis. Treatment with doxycycline and rifampin led to a clinical cure as well as to marked improvement in the Brucella titer.

Eight patients (3 male and 5 female) were treated in this study by Endovenous Laser Ablation (EVLA); Mathematical models are proposed to estimate the applied laser power and to assess the recovery period. The estimations of the applied laser power and recovery period in these models will be depended mainly on the diameter of the incompetent vein.  In addition, Excel Program was utilized to find the proposed models.  A 1470 nm diode laser up to 15W continuous power (CW) was used in the treatment of venous ulcers by EVLA procedure. Following up by duplex ultrasound was started in the 1st week after the first session until the vein is completely closed. The present study concluded that the relationship both between the applied laser power and recovery period with diameter is directly linear. The mathematical results obtained from the two mathematical proposals are consistent with the clinical results
