Since 1976, 35 transnasal operations of the maxillary sinus with endoscopic control were performed in children as treatment for chronic sinusitis. After luxation of the inferior turbinate, a mucosal flap was developed to expose the lateral bony nasal wall. A sinus fenestra was then created to allow endoscopic control of the antrum during the operation. Gross pathological alterations of the mucosa were removed while most of the lining mucosa was preserved for recovery. 30 of the 35 children were followed from 4--18 months after surgery. 28 were without any discomfort. Although X-ray studies in many of the patients revealed mucosal swelling four weeks after surgery, the maxillary sinuses were well aerated 8 weeks after operation. Transnasal sinusotomy under endoscopic control is considered to be the treatment of choice for chronic sinusitis in adults and can now also be considered to be the treatment for similar disease in children. 相似文献

Abstract – Dental injuries are rather common during sport activities and at schools where children spend most of their time every day. The purpose of this study was to evaluate the knowledge of primary school teachers in Pilsen, Czech Republic, of how to provide first aid in cases of one of the most serious dental injuries, the tooth avulsion. To this end, a questionnaire which contained nine questions about avulsion of permanent teeth was prepared. The questionnaires were distributed in nine primary schools in Pilsen where almost 300 teachers are employed. Seventy‐four percent of the teachers replied. Sixty‐eight percent had never received any information about providing first aid in cases of dental injuries and 81% would place the avulsed tooth in a dry handkerchief until the transfer of the patient to dentist. Prevention of tooth injuries is very important, as they may result even in tooth loss. This demands an effort to properly inform and educate sport trainers and primary school teachers about providing first aid in dental trauma situations; this effort should be intensive and continuous. 相似文献

Objective : To quantify the amount of Total Volatile Organic Compounds (TVOCs) emitted from five dental substances commonly used in a dental clinic. Method : An assessment of the indoor air quality in two clinics of the Athens University Dentistry Faculty was conducted. Results : It was found that TVOC emissions from Kalocryl and Bacillol reached extremely high values affecting the air in the dental clinics at short and long distances from the source. Six pollutants TVOCs, CO2, PM10, PM2.5, SO2 and NOx were measured and indoor sources associated with dental activities were identified. Very high concentrations of TVOCs were found which exceeded the acceptable levels by a factor of 20, associated with the nature of the dental activities and the ventilation conditions. The CO2 concentration levels were high and the indoor conditions were considered unsatisfactory, associated with the number of occupants and the ventilation conditions. PM concentrations were high due to the nature of the dental activities and they exceeded the outdoor levels by a factor of 5 to 6. The concentrations of the gaseous pollutants NOx were low while the SO2 concentrations were hardly detectable. 相似文献

Background
Cancer, heart failure and stroke are among the most common causes of death worldwide. Investigation of the prognostic impact of each disease is important, especially for a better understanding of competing risks. Aim of this study is to provide an overview of long term survival of cancer, heart failure and stroke patients based on the results of large population- and hospital-based studies. 相似文献108.

Background
As periprosthetic joint infections (PJIs) can have tremendous health and socioeconomic implications, recognizing patients at risk before surgery is of great importance. Therefore, we sought to determine the rate of and risk factors for deep PJI in patients undergoing primary total hip arthroplasty (THA).Methods
Clinical characteristics of patients treated with primary THA between January 1999 and December 2013 were retrospectively reviewed. These included patient demographics, comorbidities (including the Charlson/Deyo comorbidity index), length of stay, primary diagnosis, total/allogeneic transfusion rate, and in-hospital complications, which were grouped into local and systemic (minor and major). We determined the overall deep PJI rate, as well as the rates for early-onset (occurring within 2 years after index surgery) and late-onset PJI (occurring more than 2 years after surgery). A Cox proportional hazards regression model was constructed to identify risk factors for developing deep PJI. Significance level was set at 0.05.Results
A deep PJI developed in 154 of 36,494 primary THAs (0.4%) during the study period. Early onset PJI was found in 122 patients (0.3%), whereas late PJI occurred in 32 patients (0.1%). Obesity, coronary artery disease, and pulmonary hypertension were identified as independent risk factors for deep PJI after primary THA.Conclusion
The rate of deep PJIs of the hip is relatively low, with the majority occurring within 2 years after THA. If the optimization of modifiable risk factors before THA can reduce the rate of this complication remains unknown, but should be attempted as part of good practice. 相似文献109.

Purpose: End‐to‐side (ETS) nerve repair allows for target‐muscle reinnervation, with simultaneous preservation of donor‐nerve function. Acetyl‐L‐carnitine (ALCAR) was shown to enhance axonal sprouting in early regeneration following transection and repair of the sciatic nerve in rodents. The purpose of this article was to determine the ability of ALCAR to enhance axonal regeneration in an ETS rodent model. Method: The right musculocutaneous nerve in 16 adult male Sprague‐Dawley rats was transected to induce biceps muscle paralysis. The distal stump was then coapted by ETS neurorrhaphy through a perineurial window to the ipsilateral median nerve. Experimental groups received ALCAR for 1, 2, 3, and 4 weeks whereas controls received placebo. Results: Weekly postoperative behavioral evaluations revealed increased functional return over control but the difference was not significant. Potentials from biceps were recorded from the third postoperative week in the experimental group and from the fourth week in the control group. Histomorphometric evaluations revealed higher musculocutaneous nerve axon counts, higher myelin thickness in the fourth postoperative week, and differences in the appearance and the number of motor‐end‐plates in the biceps in experimental versus control group. Conclusion: Intraperitoneal administration of ALCAR can expedite biceps muscle recovery in an ETS model by increasing the rate of axonal regeneration. Despite the morphological changes, no behavioral changes were noted and further studies are needed to confirm clinical efficacy of ALCAR for potential use in the development of therapeutic protocols. © 2009 Wiley‐Liss, Inc.
