Aim： To investigate the causes and costs of flexible ureteroscope damage, and to develop recommendations to limit damage. Methods： The authors analysed repair figures and possible causes of damage to 35 instruments sent for repair to a leading UK supplier over a 1-year period, and calculated cost figures for maintenance of the instruments as opposed to repair and replacement costs. Results： All damages were handling-induced and therefore did not fall under the manufacturer＇s warranty： 28 % were damaged by misfiring of the laser inside the instrument; 72 %, mainly crushing and stripping of the ureteroscope shaft tube, were likely to have occurred during out-of-surgery handling, washing and disinfection. Seventeen （4 %） instruments were not repaired and consequently taken out of service due to the extensive costs involved. Eighteen （51%） ureteroscopes were repaired at an average cost of 10 833 USD. Conclusion： Damages to flexible ureteroscopes bear considerable costs. Most damages occur during handling between surgical procedures. Thorough adherence to handling procedures, and courses for theater staff and surgeons on handling flexible instruments may help to reduce these damages and prove a cost-saving investment. The authors provide a list of recommended procedural measures that may help to prevent such damages.

Al-Halabi is an intriguing ophthalmologist who invented numerous surgicalinstruments for treating various eye diseases. The illustrations of such instrumentsin his invaluable book “Kitab Al-Kafi fi Al-Kuhl” reflect his willingness toteach. Moreover, he included in his book a magnificent illustration of theanatomical structure of the eye. The book reflects Al-Halabi’s medical practice andteaching and shows several advanced medical techniques and tools. Hisinvaluable comments reflect his deep experimental observations in the field ofophthalmology. The current article provides proof that Al-Halabi is one of ourearly biomedical engineers from more than 800 years ago. Al-Halabi represents aring in the chain of biomedical engineering history. His surgical instrumentsrepresent the biomechanics field. Al-Halabi should be acknowledged among thebiomedical engineering students for his various contributions in the field ofsurgical instruments.

Objective:To investigate the relationship between serum electrolyte changes and cisplatin induced ***:We collected data from 18 patients undergoing cisplatin chemotherapy including serum electrolytes,creatinine,blood urea nitrogen(BUn) and urine potassium,sodium and pH levels before and after the cisplatin *** the patients had cancer and were treated with 40-50 mg/day *** injury was assessed by measuring serum electrolytes,creatinine,BUn levels and urine potassium,sodium and pH levels. Results:The five cycles of cisplatin based chemotherapy resulted in hypomagnesia(P=0.029), hypocalcaemia(P=0.001~*),hypophosphatemia(P=0.003*),hypokalemia(P=0.001~*)and increased serum creatinine(P=0.001~*)and BUn(P=0.292~*)*** urine analysis,decrease in potassium(P=0.024~*)was found,except potassium there was no significant changes in sodium and urine pH. Conclusions:The present study demonstrates that,acute nephrotoxicity was observed in patients with different types of cancers undergoing cisplatin based chemotherapy due to electrolyte disturbances,when no corrective measures were initiated.

在当今美国,电视作为一种传播媒介和科技产品,具有双重性。一方面,电视是反思考、反智力的,它将复杂的事物进行简单化、娱乐化的处理后再呈现给观众;另一方面,电视的图像化和直观化等特点又使它成为用于历史教学的一种重要方式。对于历史教学来说,电视是挑战,但更应成为机遇。电视提供了一个多媒体平台,通过图像、声音和表格等多元化的表达方式与观众形成互动,从而更加高效地传播历史知识。因此,更多的电视节目需要充分利用电视这一媒介来传播历史知识,历史学者也需要通过电视来传播他们最新的研究成果。

作者： Abhijit n Gurav Department of Periodontology Tatyasaheb Kore Dental College and Research Centre

Periodontitis is the commonest oral disease affecting population worldwide. This disease is notorious for the devastation of tooth supporting structures, ensuing in the loss of dentition. The etiology for this disease is bacterial biofilm, which accumulates on the teeth as dental plaque. In addition to the biofilm microorganisms, other factors such as environmental, systemic and genetic are also responsible in progression of periodontitis. Diabetes mellitus (DM) is metabolic disorder which has an impact on the global health. DM plays a crucial role in the pathogenesis of periodontitis. Periodontitis is declared as the “sixth” major complication of DM. Evidence based literature has depicted an enhanced incidence and severity of periodontitis in subjects with DM. A “two way” relationship has been purported between periodontitis and DM. Mutual management of both conditions is necessary. Periodontal therapy (PT) may assist to diminish the progression of DM and improve glycemic control. Various advanced technological facilities may be utilized for the purpose of patient education and disease management. The present paper clarifies the etio-pathogenesis of periodontitis, establishing it as a complication of DM and elaborating the various mechanisms involved in the pathogenesis. The role of PT in amelioration of DM and application of digital communication will be discussed. Overall, it is judicious to create an increased patient cognizance of the periodontitis-DM relationship. Conjunctive efforts must be undertaken by the medical and oral health care professionals for the management of periodontitis affected DM patients.
