The common cavity vs incomplete partition type I conundrum: Decision making and management with the cochlear implant form electrode

Abstract Objective To determine the effect of cochlear dimensions on cochlear implant selection in cochlear hypoplasia patients. Methods Temporal bone computed tomography images of 36 patients diagnosed with cochlear hypoplasia between 2010 and 2016 were retrospectively reviewed and compared with those of 40 controls without sensorineural hearing loss. Results Basal turn length and mid-modiolar height were significantly lower in the cochlear hypoplasia patients with subtypes I, II and III than in the control group (p < 0.001). Mid-scalar length was significantly shorter in subtype I–III patients as compared with the control group (p < 0.001). In addition, cochlear canal length (measured along the lateral wall) was significantly shorter in subtype I–IV patients than in the control group (subtypes I–III, p < 0.001; subtype IV, p = 0.002) Conclusion Cochlear hypoplasia should be considered if basal turn length is less than 7.5 mm and mid-modiolar height is less than 3.42 mm. The cochlear implant should be selected according to cochlear hypoplasia subgroup. It is critically important to differentiate subtype II from incomplete partition type I and subtype III from a normal cochlea, to ensure the most appropriate implant electrode selection so as to optimise cochlear implantation outcomes.

Incomplete Partition

Background: Patients with cochlear malformations were long considered poor candidates for cochlear implantation (CI), and surgical approaches different than the standard facial recess approach were used to access the inner ear. There is no previous long-term follow-up of a patient with significantly malformed inner ear operated through an untraditional route and requiring a revision surgery. Purpose: This case provides a long-term follow-up from the initial surgery, a short-term follow-up from the revision surgery, and it illustrates the evolving classification of inner ear malformations as well as the potential problems associated with nonstandard approaches to the cochlea. Research Design: A case report. Intervention: Herein, we report a case of revision CI in a patient with incomplete partition type I, through the round window via a facial recess approach, 18 yr after an initial implantation via a transmastoid labyrinthotomy approach. Results: The patient had an uncomplicated surgery, and after activation, she noted auditory perception on all electrodes without facial stimulation. A sound field sound awareness threshold was obtained at 15 dB HL. Conclusions: As the prior generation of cochlear implant recipients ages, the probability of a revision surgery for various causes increases. Cochlear implant surgeons should be aware of the potential pitfalls associated in these often challenging cases.

Subject. The study addresses the improvement of risk management efficiency and the quality of lending decisions made by banks. Objectives. The aim is to present the bank management with a fair algorithm for risk management motivation on the one hand, and the credit management (business) on the other hand. Within the framework of the common goal to maximize risk-adjusted income from loans, this algorithm will provide guidelines for ‘risk management’ and ‘business’ functions on how to improve individual and overall efficiency. Methods. The study employs the discriminant analysis, type I and II errors, Lorentz curve modeling, statistical analysis, economic modeling. Results. The paper offers a mechanism for assessing the quality of risk management decisions as opposed to (or in support of) decisions of the lending business when approving transactions. The mechanism rests on the approach of stating type I and II errors and the corresponding classical metric of the Gini coefficient. On the ‘business’ side, the mechanism monitors the improvement or deterioration of the indicator of changes in losses in comparison with the market average. Conclusions. The study substantiates the stimulating ‘rules of the game’ between the ‘business’ and ‘risk management’ to improve the efficiency of the entire business, to optimize interactions within the framework of internal competition. It presents mathematical tools to calculate corresponding indicators of the efficiency of internally competing entities.

Abstract The changes to the Irish exclusionary rule introduced by the judgment in People (DPP) v JC mark an important watershed in the Irish law of evidence and Irish legal culture more generally. The case relaxed the exclusionary rule established in People (DPP) v Kenny, one of the strictest in the common law world, by creating an exception based on ‘inadvertence’. This paper examines the decision through the lens of legal culture, drawing in particular on Lawrence Friedman's distinction between ‘internal’ and ‘external’ legal culture to help understand the factors contributing to the decision. The paper argues that Friedman's concept and, in particular, the dialectic between internal and external legal culture, holds much utility at a micro as well as macro level, in interrogating the cultural logics at work in judicial decision-making.

1. The antigenic function of a pneumococcus vaccine made from the intact cell was compared with that derived fron a watery extract of the cell free from formed elements. In each instance, the immunity produced was dependent upon type-specific protective substance and not upon the elaboration of the common protein antibody. 2. The vaccine made from the intact cell resulted in both active and passive immunity which began on the 3rd day, increased markedly to the 5th, and remained approximately stationery to the 7th day. In the case of the Berkefeld filtrate of the shaken bacteria and the filtrate of the broth culture, the immunity began on the 4th day, increased to the 5th, and remained approximately stationery to the 7th day. The immunity produced by Pneumococcus Type I vaccine is greater than that produced by Type II. On the 3rd day, mice vaccinated with Type I vaccine resisted 100,000 minimal lethal doses, whereas mice immunized with Type II resisted 10,000 minimal lethal doses. On the 5th day, a larger percentage of mice survived these doses than on the 3rd day. 3. Certain factors related to the preparation and dosage of the vaccine are discussed. 4. As far as the time interval and the degree of immunity produced are concerned, these results suggest the possibility of employing pneumococcus vaccine in suitable doses in the treatment of lobar pneumonia. That an earlier activity of the immunity mechanism could actually be initiated in a patient with lobar pneumonia has still to be demonstrated.

Ear Anomalies

Abstract Background Hearing loss management using cochlear implants in patients with inner ear anomalies has long been discussed in the otology community. Magnetic resonances imaging (B,/IRI) and Computed tomography (CT) play important roles in the preoperative assessment of inner ear abnormalities such as cochlear nerve deficiency and variant anatomy as these abnormalities may not only affect the decision of the implantation procedure or the patient's prognosis regarding auditory improvement, but also the risk of complications. Objective To examine the prevalence of inner ear anomalies among cochlear implant recipients in patients with congenital sensorineural hearing loss among the pediatric age group in the Demerdash hospital, Ain Shams university using High resolution computed tomography (HRCT) and MRI imaging. Methods A retrospective descriptive study over the course of 9 months that included all patients that are candidates for cochlear implant referred to the Radiology department, Ain Shams University Hospitals for a preoperative imaging in the form of CT and VIRI scans. Results CT and MRI scans of 33 patients who had congenital hearing loss and were candidates for cochlear implantation with total 66 ears were reviewed. Inner ear anomalies were identified in 8 patients representing a prevalence (24.2%) with 14 ear diseased. Anomalies were seen bilaterally in 6 patients and unilaterally in 2 patients. Among the 14 diseased ear, 9 ears (64.3%) were seen with incomplete partition Il, 7 ears (50%) were seen with enlarged vestibular aqueduct, 4 ears (28.6%) were seen with cochlear hypoplasia, 3 ears (21.4%) were seen with semicircular canal aplasia, 2 ears (14.3%) were seen with incomplete partition type I, 2 ears (14.3%) were seen with cochlear nerve aplasia, 2 ears with cochlear aplasia (14.3%), I ear (7.1%) was seen with common cavity ear (7.1%) with complete labyrinthine aplasia. Conclusion Prevalence of inner ear anomalies among cochlear implant candidates was 24.2%. This result is consistent with results worldwide and the most common anomalies were Incomplete partition Il and large vestibular aqueduct.

Of late years, while the structure of the skull has greatly occupied me, the rest of the skeleton has been neglected in comparison. A quarter of a century ago, or more, the whole skeleton, in Birds especially, occupied much of my thought; and from an even earlier period I have never ceased to gather together embryos and young Birds of all kinds, which should some day serve for a renewal of the work. In this short paper, dealing with a single region, and that principally in a single type, I give the first-fruits of a revised study of the Bird’s skeleton. Many recent workers have dealt with the development of one part or other of the Bird’s wing ; but it seemed to me that we had from none of them a minute account of the successive changes in any one form. And now, having made such a study, I think I have not failed to draw some new facts from it.
