Twenty four cases of subdural empyema are reviewed. The overall mortality was 17%, 18 patients were managed by burr hole and five by craniotomy or craniectomy. Antibiotic therapy was commenced once pus had been evacuated. Infection of the paranasal and mastoid sinuses was the commonest aetiological factor. Aspiration of pus through burr holes is the recommended surgical procedure with low morta...

over the whole of the hepatic area was swollen, red and shining, and distinct fluctuation was detected. The patient's low condition contra-indicated any severe or prolonged operation; so I contented myself with puncturing the fifth intercostal space, and drew off three pints of offensivesmelling pus, mixed with debris of hepatic tissue through an aspirator needle. She became very prostrate from...

retained surgical gauze is occasionally observed in general practice. herein, we report a case with surgical gauze retained for over 13 years that created a fistula which drained pus into the stomach.

  Actinnomycetoma is a relatively rare chronic pustular infection. Thirty four cases have been reported from various geographic locations in  Iran. In this case report, a fifty year old male patient with Actinomycotic mycetoma lesions in his right foot was studied. Studies of the direct smear and culturing of the specimens ( both pus and & exudate, collected from the lesions), revealed that No...

In most economic sectors organizations face rapid environmental changes like regulations. Such changes can force them to adjust both their organizational and operational structure. For instance, in the energy utility sector numerous developments moved German Public Utilities (PUs) towards a liberalized market. Nowadays PUs have to stay competitive while managing a heterogeneous information tech...

We study the performance of an opportunistic spectrum access (OSA) system with a general number of channels and imperfect spectrum sensing. The OSA system consists of a primary system serving primary users (PUs) and a secondary system serving secondary users (SUs). The PUs have strict priority over the SUs and the SUs opportunistically access the channels not occupied by the PUs temporarily. Th...

Due to limited cooperation among users and erratic nature of wireless channel, it is difficult for secondary users (SUs) to obtain exact values of system parameters, which may lead to severe interference to primary users (PUs) and cause communication interruption for SUs. In this paper, we study robust power control problem for spectrum underlay cognitive radio networks with multiple SUs and PU...

Little is known about the changes in gut resident flora during amebic colitis and amebic liver abscess (ALA) caused by Entamoeba histolytica infection. Fecal samples from ALA patients, from healthy E. histolytica negative and positive (asymptomatic) individuals, and from pre- and post-metronidazole-treated healthy volunteers and pus samples from ALA patients were tested for the presence of vari...

Multiple-input multiple-out (MIMO) and cognitive radio (CR), can both effectively participate in the transmission interference among links and thus increase the network throughput in wireless communications. The goal of this work is to develop a distributed algorithm that can concurrently exploit the agility of CR and MIMO to benefit from both the opportunities of spare spectrum channels and sp...

PURPOSE We present a case of orbital abscess following porous orbital implant infection in a 73-year-old woman with rheumatoid arthritis. METHODS Just one month after a seemingly uncomplicated enucleation and porous polyethylene (Medpor) orbital implant surgery, implant exposure developed with profuse pus discharge. The patient was unresponsive to implant removal and MRI confirmed the presenc...
