Incidence and Preoperative Predictive Indicators of Incudal Necrosis in CSOM: A Prospective Study in a Tertiary Care Centre.

ABSTRACT: Both type of CSOM, tubotympanic which is considered safe as well as atticoantral which is considered unsafe may lead to erosion of the ossicular chain. Discontinuity of the ossicular chain is typically confirmed only during an operation. Knowing before surgery whether the patient has an ossicular discontinuity is important because it allows the surgeon to know the possibility of performing an ossiculoplasty and obtaining patient consent. The aims is to (1) study the incidence of incus necrosis in safe and unsafe CSOM. (2) Determine the preoperative predictive factors for incus necrosis. (3) Use angled otoscopes to determine the incidence of residual disease peroperative after conventional microscopic surgery. This is a prospective study carried out in the department of otorhinolaryngology, Govt Doon medical college, Dehradun from July 2014 to July 2016. A total of 100 patients who presented with CSOM and have not undergone any surgical procedure for the same were included in this study. Patients group was divided into cholesteatoma and non cholesteatoma group. Both groups were subdivided into intact and eroded incus group and were analysed in 11 parameters which were compared statistically. Incudal necrosis is more common in cholesteatoma group. In non cholesteatoma ears subtotal perforation with exposure of IS joint is reliable indicators of incudal necrosis. In non cholesteatoma group extension of cholesteatoma to tympanic sinus and mastoid and presence of persistent discharge are reliable indicators of necrosed incus. Moderate to moderately severe hearing loss indicate incudal necrosis in both groups therefore we conclude that these parameters can be reliably considered as predictors for incudal necrosis preoperatively.

Project description:Asymptomatic myocardial injury following noncardiac surgery (MINS) is an independent predictor of 30-day mortality and may go unrecognized based on standard diagnostic definition for myocardial infarction (MI). Given lack of published research on MINS in India, our study aims to determine incidence of MINS in patients undergoing noncardiac surgery at our tertiary care hospital, and evaluate the clinical characteristics including 30-day outcome.The prospective observational study included patients >65 years or >45 years with either hypertension (HTN), diabetes mellitus (DM), coronary artery disease (CAD), cerebrovascular accident (CVA), or peripheral arterial disease undergoing noncardiac surgery. MINS was peak troponin level of ?0.03 ng/dL at 12-hour or 24-hour postoperative. All patients were followed for 30 days postoperatively. Predictors of MINS and mortality were analyzed using multivariate logistic regression. Patients categorized based on peak troponin cut-off values determined by receiver operating characteristic curve were analyzed by Kaplan-Meir test to compare the survival of patients between the groups.Among 1075 patients screened during 34-month period, the incidence of MINS was 17.5% (188/1075). Patients with DM, CAD, or who underwent peripheral nerve block anaesthesia were 1.5 (P?<?.01), 2 (P?<?.001), and 12 (P?<?.001) times, respectively, more likely to develop MINS than others. Patients with heart rates ?96 bpm before induction of anesthesia were significantly associated with MINS (P?=?.005) and mortality (P?=?.02). The 30-day mortality in MINS cohort was 11.7% (22/188, 95% CI 7.5%-17.2%) vs 2.5% (23/887, 95% CI 1.7%-3.9%) in patients without MINS (P?<?.001). ECG changes (P?=?.002), peak troponin values >1 ng/mL (P?=?.01) were significantly associated with mortality. A peak troponin cut-off of >0.152 ng/mL predicted mortality among MINS patients at 72% sensitivity and 58% specificity. Lack of antithrombotic therapy following MINS was independent predictor of mortality (P?<?.001), with decreased mortality in patients who took post-op ASA (Aspirin) or Clopidogrel. Mortality among MINS patients with post-op ASA intake is 6.7% vs 12.1% among MINS patients without post-op ASA intake. Mortality among MINS patients with post-op Clopidogrel intake is 10.5% vs 11.8% among MINS patients without post-op Clopidogrel intake.A higher (17.5%, 95% CI 15-19%) incidence of MINS was observed in our patient cohort with significant association with 30-day mortality. Serial postoperative monitoring of troponin following noncardiac surgery as standard of care, would identify "at risk" patients translating to improved outcomes.

Project description:ObjectiveThe paucity of specialised care in the peripheral areas of developing countries necessitates the referral of sick neonates to higher centres. Organised interhospital transport services provided by a skilled and well-equipped team can significantly improve the outcome. The present study evaluated the transport characteristics and predictors of mortality among neonates referred to a tertiary care centre in North India.DesignProspective observational study.SettingsTertiary care teaching hospital in North India.Patients1013 neonates referred from peripheral health units.Main outcome measuresMortality among referred neonates on admission to our centre.ResultsOf the 1013 enrolled neonates, 83% were transferred through national ambulance services, 13.7% through private hospital ambulances and 3.3% through personal vehicles. Major transfer indications were prematurity (35%), requirement for ventilation (32%), birth asphyxia (28%) and hyperbilirubinaemia (19%). Hypothermia (32.5%, 330 of 1013), shock (19%, 192 of 1013) and requirement for immediate cardiorespiratory support (ICRS) (10.4%, 106 of 1013) on arrival were the major complications observed during transfer. A total of 305 (30.1%, N=1013) deaths occurred. Of these, 52% (n=160) died within 24 hours of arrival. On multivariate logistic analysis, unsupervised pregnancy (<4 antenatal visits; p=0.037), antenatal complications (p<0.001), prematurity ≤30 weeks (p=0.005), shock (p=0.001), hypothermia (p<0.001), requirement for ICRS on arrival (p<0.001), birth asphyxia (p=0.004), travel time >2 hours (p=0.005) and absence of trained staff during transfer (p<0.001) were found to be significant predictors of mortality.ConclusionThe present study depicts high mortality among infants referred to our centre. Adequate training of peripheral health personnel and availability of pre-referral stabilisation and dedicated interhospital transport teams for sick neonate transfers may prove valuable interventions for improved outcomes.

Project description:Birth centres are described as settings where women with uncomplicated pregnancies can give birth in a home-like environment assisted by midwives and maternity care assistants. If complications arise or threaten, the woman is referred to a maternity unit of a hospital where an obstetrician will take over responsibility. In the last decade, a number of new birth centres have been established in the Netherlands, based on the assumption that birth centres provide better quality of care since they offer a better opportunity for more integrated care than the existing system with independent primary and secondary care providers. At present, there is no evidence for this assumption. The Dutch Birth Centre Study is designed to present evidence-based recommendations for organization and functioning of future birth centres in the Netherlands. A necessary first step in this evaluation is the development of indicators for measuring the quality of the care delivered in birth centres in the Netherlands. The aim of this study is to identify a comprehensive set of structure and process indicators to assess quality of birth centre care.We used mixed methods to develop a set of structure and process quality indicators for evaluating birth centre care. Beginning with a literature review, we developed an exhaustive list of determinants. We then used a Delphi study to narrow this list, calling on experts to rate the determinants for relevance and feasibility. A multidisciplinary expert panel of 63 experts, directly or indirectly involved with birth centre care, was invited to participate.A panel of 42 experts completed two Delphi rounds rating determinants of the quality of birth centre care based on their relevance (to the setting) and feasibility (of use). A set of 30 determinants for structure and process quality indicators was identified to assess the quality of birth centre care in the Netherlands.We identified 30 determinants for structure and process quality indicators concerning birth centre care. This set will be validated during the evaluation of birth centres in the Dutch Birth Centre Study.
