Purpose.This study retrospectively analyzed cataract surgeries to examine the usefulness of Surgical Media Center (SMC) (Abbott Medical Optics Inc.), a new cataract surgery recording device, for training of cataract surgery.Methods.We studied five hundred cataract surgeries conducted with a phacoemulsification system connected to the SMC. After surgery, the surgical procedures were reviewed, with changes in aspiration rate, vacuum level, and phaco power displayed as graphs superimposed on the surgical video. We examined whether use of SMC is able to demonstrate the differences in technique between experienced and trainee operators, to identify inappropriate phacoemulsification techniques from analyzing the graphs, and to elucidate the cause of intraoperative complications.Results. Significant differences in the time taken to reach maximum vacuum and the speed of increase in vacuum during irrigation and aspiration were observed between experienced and trainee operators. Analysis of the graphs displayed by SMC detected inappropriate phacoemulsification techniques mostly in cases operated by trainee operators.Conclusions. Using SMC, it was possible to capture details of cataract surgery objectively. This recording device allows surgeons to review cataract surgery techniques and identify the cause of intraoperative complication and is a useful education tool for cataract surgery.

Purpose. To evaluate intraoperative complications and utilization of adjunctive devices between microscope and intracameral illuminations during cataract surgery in the elderly over 75 years. Design. A retrospective, consecutive, interventional case series Participants. Two hundred eighty-six eyes of 184 patients older than 75 years who underwent cataract surgery using microscope and intracameral illuminations. Methods. A chart review was performed on an advanced cataract surgery group of 141 consecutive cases in which the intracameral illumination was used and on a standard cataract surgery group of 145 consecutive cases in which the intracameral illumination was not used. Main Outcome Measures. Intraoperative complications (posterior capsule rupture, radial tear of the anterior capsule, dropped nucleus, or sulcus-implanted/sclera-fixated IOL) and utilization of adjunctive devices (pupil expansion device or anterior capsule staining). Results. The frequency of use of the pupil expansion device was lower in the advanced cataract surgery group than that in the standard cataract surgery group (0.7% vs 6.9%; p=0.007). Furthermore, the rates of a posterior capsule rupture and at least one intraoperative complication were lower in the advanced cataract surgery group than those in the standard cataract surgery group (0.7% vs 4.8%; p=0.067) (0.7% vs 7.6%; p=0.004). Conclusions. In the current cohort of patients over 75 years, the rate of intraoperative complications was lower when using the intracameral illumination than that when using the conventional method. Cataract surgery using intracameral illumination would be good option for elderly people.

Background: Cataract surgery is the most common operation performed in ophthalmology. It is the commonest cause of reversible blindness globally, in Sub-Saharan Africa and Nigeria. The study examined some factors affecting the outcome of cataracts surgery measured by Visual acuity after 6 weeks. Methods: Data was collected from the records of ophthalmic patients who had cataract surgery at LAUTECH Teaching Hospital Ogbomoso, from the period of January 2013 to December 2018. Two hundred and twenty-seven patients’ records were retrieved for the study. Logistic Regression was used to investigate factors associated with the outcome of Cataracts Surgery. The goodness of fit test was used to determine the fit of the model to the data. Results: Two variables; intraoperative complication, and unaided visual acuity on the fir st postoperative day were statistically significant (p-value < 0.05). The outcome of surgery using unaided visual acuity after six weeks of surgery showed that 47.1% of the patients had a good visual outcome (6/18) or better and 52.9% had a poor outcome (worse than 6/60). Factors such as complications within six weeks, presence of ocular and systemic comorbidity, and presence of intraoperative complications were found to increase the likelihood of poor outcomes in cataract surgery. Conclusion: This study has shown that Intraoperative complications and unaided visual acuity on the first postoperative day are important to the outcome of cataract surgery. Therefore, the two factors should be given attention during cataract surgery

Objectives: The three dimensional (3D) endoscope is considered as a new surgical tool which used in different approaches in intranasal and anterior skull base surgical procedures. There are many advantages of the 3D endoscopy over the two dimensional (2D) one that have been demonstrated along clinical applications, surgical training and different experimental studies. Our study aimed to show the difference between using the 3D & 2D endoscopes during endonasal and anterior skull base surgery and its importance specially when used by novice users. Design: Our study is divided into two phases (clinical & cadaveric phases).In the clinical study we have done 52 endonasal & anterior skull base surgical procedures (26 study cases and 26 control cases).We recorded accuracy, duration and intraoperative complication for each case. The cadaveric study was performed on three cadavers, difference in accuracy and dissection time were recorded using 3D & 2D endoscopy for each side chosen by randomization. Results: In the clinical study, the cases done by 3D endoscope were significantly faster and more accurate with less intraoperative complications compared to cases done using 2D endoscope. In cadaveric dissection while using 3D endoscope there was better depth of perception regarding the anatomical landmarks compared to 2D endoscope. Conclusion: 3D endoscopy is an advanced instrument that allows better training for the coming generation of ENT surgeons. Both clinical and cadaveric studies offer a promising outcomes in both endonasal and anterior skull base surgery.

Background. Phacoemulsification is the most important cataract surgical procedure performed by ophthalmology residents. There is an increasing and consistent trend in international studies on decreased complication rates and more efficient surgical techniques with more surgeries performed. The data collected from this study can be used to quantitatively assess the cataract surgery training of Ophthalmology residents in the country and can help to improve the quality of cataract surgeries taught and performed in the training programs. Objectives. To analyze outcomes of phacoemulsification cataract surgeries and to determine the intraoperative complication rates of third-year residents of the University of the Philippines - Philippine General Hospital (UP-PGH). Methods. Retrospective chart review of phacoemulsification cases done by eight third-year ophthalmology residents at the UP-PGH from January 1 to December 31, 2017. Outcomes measured included postoperative best corrected visual acuity (BCVA), intraoperative complications (posterior capsular rent and vitreous loss), and adjusted phacoemulsification times (total phacoemulsification time multiplied by phacoemulsification power used). Results. Four hundred ninety-two (492) cases were analyzed. Postoperative mean BCVA was 20/25. There were no significant differences in visual acuity outcomes over the course of training. Intraoperative complications occurred in 33 cases, with fewer cases with posterior capsule rent and vitreous loss later in training after the first 50 cases. There was a downward trend of adjusted phacoemulsification time throughout training, with a significant difference between the first 50 and 100 cases. Conclusion. Good visual outcomes are achievable throughout the resident’s phacoemulsification learning curve. Surgical competency in phacoemulsification, as measured by complication rates and phacoemulsification efficiency, still improves significantly with an increasing number of cases and experience beyond the first 100 cases.

Abstract Introduction. Cataract surgery is one of the most important surgical procedures in ophthalmology. Aim. The aim of this study is to compare cataract surgeries performed in 1994 and 2014. Material and methods. A retrospective analysis of 100 cataract procedures in 1994, as well as a total of 100 cataract procedures performed in 2014. The authors considered the following factors: age, sex, vision acuity, cataract type, preoperative patient preparation, intra- and postoperative complications, and total hospitalization time. Results. Back in 1994, extracapsular cataract extraction (ECCE) was the most common treatment technique. It caused more intraoperative complications (46) and postoperative complications (38) and longer total hospitalization time (9.25 days±3.25 SD). In 2014, all procedures were performed using phacoemulsification. As a result, the number of intraoperative (20) and postoperative (14) complications has dropped significantly. Total hospitalization time was also reduced (1.53 days±1.08 SD). Conclusions. Phacoemulsification significantly improved cataract treatment. This method is much safer and more effective than ECCE.

Abstract The use of podcasting is incredibly widespread, with experts estimating that 60 million Americans will be using podcasting in some form by 2010. The use of podcasting has grown beyond entertainment to become an educational tool, showing promise as a way to disseminate information and create networks of professional learners. However, despite the growing clinical and educational uses of podcasting in other professional disciplines, podcasting is being used primarily as a continuing education tool for speech-language pathologists and audiologists at this time. This article provides guidelines and examines the potential applications for use of podcasting in teaching and learning in communication sciences and disorders.

Objective: The primary objective of this study was to review the complication rate of percutaneous tracheostomies performed by a single surgeon in a community teaching hospital. Methods: This retrospective study reviewed the patients who underwent percutaneous tracheostomy with bronchoscopic guidance in a community hospital setting between 2009 and 2017. Patients older than the age of 18 requiring percutaneous tracheostomy were chosen for this retrospective study. Patients who were medically unstable, had no palpable neck landmarks, and inadequate neck extension were excluded. Indications for percutaneous tracheostomy included patients who had failed to wean from mechanical ventilation, required pulmonary toileting, or in whom airway protection was required. Results: Of the 600 patients who received percutaneous tracheostomy, 589 patients were included in the study. Intraoperative complication (2.6%) and postoperative complication rates (11.4%) compared similarly to literature reported rates. The most common intraoperative complications were bleeding, technical difficulties, and accidental extubation. Bleeding, tube obstruction, and infection were the most common postoperative complications. Overall burden of comorbidity, defined by Charlson Comorbidity Index, and coagulopathy were also found to be associated with higher complication rates. The decannulation rate at discharge was 46.3%. Conclusion: Percutaneous tracheostomy is a safe alternative to open tracheostomies in the community setting for appropriately selected patients.

BACKGROUND Asthma is a common chronic disease in childhood. Globally, more than 339 million people are estimated to have asthma. The prevalence of childhood asthma in India is about 6 %. Even though childhood asthma is highly prevalent, the knowledge level among parents / caregivers about the disease, its risk factors, prevention and management is poor. Currently, in India there are no national or state level bodies to provide relevant information about the disease. The rationale of this study is to create a parent education tool that will provide the necessary details about the disease and to check the effectiveness by assessing the improvement in knowledge about childhood asthma among parents of wheezers after implementation of this self-prepared educational tool through a structured teaching programme. METHODS A pre-test post-test pre-experimental study was conducted among parents of children admitted to paediatric ward and intensive care unit of a tertiary care centre in North Kerala. A self-prepared questionnaire was used to assess the knowledge of parents before intervention. Intervention was done using an educational tool prepared by the researcher with the aid of power point presentation and hands on training on technique of using metered dose inhaler. Effectiveness of the tool was assessed after 10 days of intervention using the same questionnaire. Statistical analysis of collected data was done using Statistical Package for the Social Sciences (SPSS) version 26. RESULTS 51 parents were included in the study. The scoring of questionnaire before and after educational intervention was done as poor (< 10 score), average (11 - 20 score) and good (21 - 31 score). The mean score before intervention was 9.98 (SD = 3.14) and after intervention the score became 17.73 (SD = 2.562), and the difference was statistically significant (P = 0.00). Mean score of the knowledge regarding treatment and prevention of asthma improved to 10.18 (SD = 2.133) from 4.29 (SD = 2.212). CONCLUSIONS A well-developed parent education tool is a requirement for minor adjustments needed in the lifestyle of a child with asthma, which ensures proper prevention and treatment.

Cataract is a leading cause of blindness in the world, and cataract extraction is one of the most commonly performed surgeries. Preferred surgical techniques have changed over the past decades with associated improvements in outcomes and safety. Phacoemulsification is a highly successful technique first introduced over 40 years ago. It is the current method of cataract surgery, with a very low reported rate of major complications and a frequency of overall intraoperative complications of less than 2%. Application of the femtosecond laser evolved to now assist in cataract surgery and has been termed FLACS (femtosecond laser-assisted cataract surgery) and occurs in three steps: corneal incisions (including optional limbal relaxing incisions to reduce astigmatism), anterior capsulotomy, and lens fragmentation. The remaining surgical steps still require the surgeon’s hands. The FLACS technique may have some advantages compared with conventional phacoemulsification. It remains however unclear whether FLACS is globally more efficient and safer than conventional surgery. The popularity of FLACS may also be limited by its higher cost compared with conventional surgery. The potential advantages of laser-assisted surgery are yet to be determined as FLACS technology is relatively new and in continuous evolution. This chapter reports scientific data as well as our own experience with this new technology. All the platforms currently available are described.

Abstract Purpose: To report the incidence of posterior capsular rupture (PCR) of phacoemulsification and the contributing factors during the transitional period from in-patient model to ambulatory day surgery model. Method: The medical records and intraoperative complication reports were systemically reviewed during the period of August 2015 to October 2020. The PCR rate was analyzed according to the following factors: type of surgery (day surgery vs. in-patient surgery), gender, age, surgery performed in the month containing long holiday (Chinese New Year and National day), surgery performed in the first month of the residents’ rotation, increase of surgical volume comparing to the previous month, stage of the day surgery transition and whether it was before or after the implementation of safety recommendation based on clinical audit results in January 2018. The univariable logistic regression model was initially performed.Results: Within the study period, 29 493 cases of phacoemulsification surgery were enrolled in the study, 14 451 of them were performed as day surgery while 15 042 of them were inpatient surgery. The overall incidence of PCR was 1.17% (346 cases) among the 29 493 planned phacoemulsification surgery. The increase incidence of PCR was associated with older age and male gender. The incidence of PCR decreased significantly after the implementation of safety recommendations. Conclusion: The ambulatory day surgery for cataract patients could provide safe, efficient, and quality services. During the transitional period from in-patient to day surgery, careful planning and organization with dynamic clinical audit surveillance can further reduce the incidence of intraoperative complications, especially intraoperative PCR.
