ABSTRACT

Chronic eustachian tube dysfunction is a condition that affects a large number of adults every year. While many cases can be managed pharmacologically, there is a significant portion that does not respond to medical treatment alone. Invasive methods from the aural side like grommet or tympanic tube insertion have complications associated with it and often cannot address the underlying condition of the nasopharyngeal side of the eustachian tube. Balloon eustachian tuboplasty (BET) is a minimally invasive intervention that has been used successfully in countries like Germany and USA in the past decade. This paper presents the experience of a new clinical user of BET in India by retrospectively looking at the outcomes of the first 10 patients on which the procedure was performed. A marketed product EustaCare was used for the cases. There was a 90% procedural success rate within 4 weeks with one patient showing no improvement in symptoms even after 8 weeks. There were no adverse events associated with the procedure nor technical issues with the product. The product is easy to learn and use. Further study is needed to draw any conclusions on long term safety and efficacy, though historical records and preliminary results for this procedure described in this paper seem promising.

ABSTRACT

Eustachian tube dysfunction (ETD) is a common condition afflicting 1% of the adult population and is said to be higher in the pediatric population. Currently, it is primarily managed with medical therapy. However, newer management techniques like balloon tuboplasty have been introduced. To systematically review the available evidence on eustachian tube balloon dilation for treating chronic ETD covering indications, efficacy, safety, short term, and long term outcomes, a literature search was conducted on Google Scholar and Pubmed. 21 publications met the inclusion criteria. Based on the literature review the procedure was found to be effective in alleviating symptoms in adult and pediatric patients immediately postoperatively and long term, up to 5 years. The adverse event rate was 3% and these were mostly minor self-resolving complications. The perioperative protocol varies from center to center. Balloon tuboplasty was found to be safe and efficacious in the short and long term post operatively in select patients with chronic ETD.

ABSTRACT

BACKGROUND: Status epilepticus is a life-threatening, time-sensitive emergency. Acquiring an electroencephalogram (EEG) in the emergency department (ED) could impact therapeutic and disposition decisions for patients with suspected status epilepticus. OBJECTIVES: The objective of this study is to estimate the proportion of EEGs diagnostic for seizures in patients presenting to an ED with a complaint of seizures. METHODS: This retrospective chart review included adults presenting to the ED of an urban, academic, tertiary care hospital with suspected seizures or status epilepticus, who received an EEG within 24 hours of hospital admission. Data abstraction was performed by a single, trained, nonblinded abstractor. Seizures were defined as an epileptologist's diagnosis of either seizures or status epilepticus on EEG. The proportion of patients with seizures is given with confidence interval95 (CI95). RESULTS: Of 120 included patients, 67 (56%) had a history of epilepsy. Mean age was 52 years (SD, 16), 58% were White, and 61% were male. Within 24 hours, 3% had an EEG diagnostic for seizures. Electroencephalogram was obtained in the ED in 32 (27%) of 120 (CI95, 19%-35%), and 2 (6%) of 32 (CI95, 1%-19%) had seizures. Electroencephalogram was performed inpatient for 88 (73%) of 120 (CI95, 65%-81%), and 2 (2%) of 88 (CI95, 0.5%-7.1%) had seizures. CONCLUSION: Only 3% of ED patients with suspected seizures or status epilepticus had EEG confirmation of seizures within 24 hours. Early EEG acquisition in the ED may identify a group of patients amenable to ED observation and subsequent discharge from the hospital.

ABSTRACT

Many professions place significant mental and/or physical strain on their workers. Some professionals (such as firefighters, soldiers, and pilots) have an inherent responsibility for the safety of others. Making sure that workers in these remain fit for duty is an important health/safety concern for the workers and those they serve. This paper explores the viability of using EEG as a non-invasive, cost efficient method for assessing fatigue, sleep deprivation, physical exertion and stress. Specifically, P300 evoked potentials are generated in response to certain stimuli. Variations in the response characteristics (magnitude, shape, and peak shift) are explored in relation to sleep deprivation, caffeine usage, and physical exertion. Preliminary data suggests that there are quantifiable changes to the P300 response that may be attributed to fatigue.

ABSTRACT

BACKGROUND: Pulmonary surfactant is required for lung function at birth and throughout life. Lung lipid and surfactant homeostasis requires regulation among multi-tiered processes, coordinating the synthesis of surfactant proteins and lipids, their assembly, trafficking, and storage in type II cells of the lung. The mechanisms regulating these interrelated processes are largely unknown. RESULTS: We integrated mRNA microarray data with array independent knowledge using Gene Ontology (GO) similarity analysis, promoter motif searching, protein interaction and literature mining to elucidate genetic networks regulating lipid related biological processes in lung. A Transcription factor (TF)-target gene (TG) similarity matrix was generated by integrating data from different analytic methods. A scoring function was built to rank the likely TF-TG pairs. Using this strategy, we identified and verified critical components of a transcriptional network directing lipogenesis, lipid trafficking and surfactant homeostasis in the mouse lung. CONCLUSIONS: Within the transcriptional network, SREBP, CEBPA, FOXA2, ETSF, GATA6 and IRF1 were identified as regulatory hubs displaying high connectivity. SREBP, FOXA2 and CEBPA together form a common core regulatory module that controls surfactant lipid homeostasis. The core module cooperates with other factors to regulate lipid metabolism and transport, cell growth and development, cell death and cell mediated immune response. Coordinated interactions of the TFs influence surfactant homeostasis and regulate lung function at birth.
