We revised 16 patients submitted to epilepsy surgery using a new method of digital, real-time, portable electrocorticography. Patients were operated upon over a period of 28 months. There were no complications. The exam was useful in 13 cases. The low installation and operational costs, the reliability and simplicity of the method, indicate it may be useful for defining the epileptogenic regions in a variety of circumnstances, including surgery for tumors, vascular malformations, and other cortical lesions associated with seizure disorders.

The practice of maxillofacial surgery commonly entails working in anatomically confined boundaries with restricted access that can easily lead to instrument and foreign body slippage into deeper tissue planes and, rarely, be aspirated. The use of postoperative adjunctive radiographic techniques has long been used to locate any such misplaced foreign bodies to attempt removal or track their passage through the alimentary tract. The use of intraoperative computed tomography scanning has recently gained momentum; but the set up may not be easily available in all the operation theaters. As such, a definitive cost-effective technique to locate such objects remains elusive. The authors intend to share their experience with the use of the C-Arm fluoroscope for the purpose of real-time intraoperative location and attempted removal of foreign bodies in three patients. The C-Arm fluoroscope can thus be used as a cost-effective technique for real-time intraoperative imaging, compared with more expensive techniques.

Micro Structuring

Laser interference micro-structuring is a relatively efficient and cost-effective technique for fabricating periodical micro-nano-structuring surfaces. The direct fabrication of sub-micron sized dot array on silicon was performed by four interfering nanosecond laser beams with a diffractive beam splitter. The mechanism to form the dot array was analyzed and it was found that the obtained conical dot array had a negative shape of the interference pattern of four laser beams. A second-order peak between two first-order peaks also occurred due to the liquid-solid expansion.

Ocular Pressure

Glaucoma is one of the most common causes of blindness in the Western world and a major risk factor is increased intra-ocular pressure. We therefore used telemedicine in its control. Patients measured their intra-ocular pressure several times a day with a portable instrument and the values were then entered into a portable digital assistant. These data were transmitted by a modem to a central server. If the intra-ocular pressure was pathologically high, an email message was automatically sent to the ophthalmologist. The pressure curve, including a statistical analysis, was displayed in an easily readable chart format. Ten patients with glaucoma participated in a trial. Self-tonometry with telemedicine enabled continuous evaluation of the patient by the ophthalmologist. This approach offered the advantage of controlling the treatment remotely. Advantages for the patient were that the measurements were easily done at home under normal conditions, and the patient could control when the measurement and data transmission would be performed. Telemedicine is a cost-effective technique enabling the early diagnosis of pathologically increased intra-ocular pressure.

Castor bean (Ricinus communis) seeds contain ricinine, an alkaloid with insecticidal and insectistatic activities. Elicitation with salicylic acid (SA) has proven to stress R. communis and might modify the ricinine concentration. The aim of this study was to evaluate the concentration of ricinine in the bagasse of seeds from R. communis elicited with exogenous SA under greenhouse conditions. Plants were grown and divided into five groups, which were sprayed with SA and drench with 50 mL 60 days after sowing with concentrations of SA (0, 100, 300, 600 and 900 µM). Clusters were mixed and separated according to the treatment, and dried. The seeds were ground, the oil was extracted by Soxhlet with hexane, and then the bagasse was extracted with methanol. Ricinine was determined by HPLC. Elicitation did not change the plant height or diameter; the control group had 9.17 µg mL−1 of ricinine; and the concentrations followed a hormesis curve with the peak at 300 µM of SA that had a ricinine concentration of 18.25 µg mL−1. Elicitation with SA might be a cost-effective technique to increase ricinine from R. communis bagasse.

AbstractObjective:We report the use of triamcinolone injections to correct severe nasal deformity due to sarcoidosis, as an alternative to formal surgical rhinoplasty.Case report:A 30-year-old woman with a long-standing history of sarcoidosis presented to a tertiary referral rhinology clinic complaining of breathing difficulty and nasal deformity. Flexible nasoendoscopy revealed red nasal plaques typical of nasal sarcoidosis, together with significant widening of the nasal bridge. Triamcinolone, a long-acting corticosteroid, was injected both intralesionally and subcutaneously over the nasal dorsum, at zero, three and eight months, resulting in long-lasting improvement of the nasal shape.Conclusion:Sarcoidosis is a non-caseating, granulomatous, epithelioid inflammation. Otorhinolaryngological manifestations occur in approximately 10 per cent of patients; however, there is little published experience of nasal reconstruction in such patients. We describe a quick, simple and relatively cost-effective technique, with little or no co-morbidity, with which to improve the aesthetic and symptomatic outcomes of nasal sarcoidosis.
