A case of accidental self-enucleation caused by obstructive sleep apnea.

A novel form of injury associated with obstructive sleep apnea (OSA) that was comorbid with obesity hypoventilation syndrome and severe daytime somnolence is reported in a 55-year-old woman, manifesting as severe ocular and extraocular muscle injuries sustained from suddenly falling asleep and colliding with a sharp object, resulting in surgical enucleation of the right eye and orbital implant. The literature on injuries (falls, motor vehicle accidents) related to OSA and excessive day time sleepiness is reviewed, along with the literature on injuries from OSA-related parasomnias. The diverse health hazards, including physical injury, associated with OSA-excessive daytime sleepiness, are emphasized, further encouraging the need to educate primary care providers on early detection of OSA with prompt treatment intervention.

Nicotine-induced survival signaling in lung cancer cells is dependent on their p53 status while its down-regulation by curcumin is independent.

BACKGROUND: Lung cancer is the most lethal cancer and almost 90% of lung cancer is due to cigarette smoking. Even though nicotine, one of the major ingredients of cigarette smoke and the causative agent for addiction, is not a carcinogen by itself, several investigators have shown that nicotine can induce cell proliferation and angiogenesis. We observed that the proliferative index of nicotine is different in the lung cancer cell lines H1299 (p53-/-) and A549 (p53+/+) which indicates that the mode of up-regulation of survival signals by nicotine might be different in cells with and without p53. RESULTS: While low concentrations of nicotine induced activation of NF-κB, Akt, Bcl2, MAPKs, AP1 and IAPs in H1299, it failed to induce NF-κB in A549, and compared to H1299, almost 100 times higher concentration of nicotine was required to induce all other survival signals in A549. Transfection of WT-p53 and DN-p53 in H1299 and A549 respectively, reversed the mode of activation of survival signals. Curcumin down-regulated all the survival signals induced by nicotine in both the cells, irrespective of their p53 status. The hypothesis was confirmed when lower concentrations of nicotine induced NF-κB in two more lung cancer cells, Hop-92 and NCI-H522 with mutant p53 status. Silencing of p53 in A549 using siRNA made the cells susceptible to nicotine-induced NF-κB nuclear translocation as in A549 DN-p53 cells. CONCLUSIONS: The present study reveals a detrimental role of nicotine especially in lung cancer patients with impaired p53 status and identifies curcumin as a potential chemopreventive.

Remifentanil/Thiopental combination and seizure length in electroconvulsive therapy.

In an effort to see if use of high-potency opioid combined with lower-than-usual dose barbiturate results in longer seizure length in electroconvulsive therapy, we retrospectively examined data from 56 patients. For each case, 1 seizure with thiopental alone and 1 with thiopental combined with remifentanil were compared. Longer mean electroencephalographic seizure length with the combination slightly missed statistical significance, whereas motor seizure duration was not statistically significantly different between the 2 strategies. We conclude that if thiopental is used for anesthetic induction in electroconvulsive therapy in the dose range described herein, modest dose reduction and combination with remifentanil does not reliably prolong seizure duration.

A Case of Buspirone Demonstrating Immediate and Sustained Benefit in a Man With Lifelong Non-Rapid-Eye-Movement Parasomnias.

BACKGROUND: Non-rapid-eye-movement (NREM) parasomnias are disorders of sleep ranging from confusional arousals to sleepwalking and sleep-related eating disorders. Historically, antidepressants and benzodiazepines were recommended in treatment of NREM parasomnias. In this case report, we are reporting the use of buspirone in a patient with NREM parasomnias, which produced substantial resolution of symptoms. CASE PRESENTATION: A 38-year-old man presented with confusional arousals and somnambulism. In addition, the patient had significant anxiety with work-related stress. Given the patient's concerns of side effect profile of other medications indicated in NREM parasomnias and the patient's history of anxiety, we started the patient on buspirone. The patient had significant improvement in his symptoms immediately after starting the medication with sustained relief from symptoms. CONCLUSION: Buspirone can be considered an effective alternate treatment option for NREM parasomnias when other medications are not preferred or cannot be prescribed.

Two Cases of Sleep-Related Eating Disorder Responding Promptly to Low-Dose Sertraline Therapy.

ABSTRACT: We report two cases of adult males with sleep-related eating disorder (SRED), with durations of 3 and 7 years, and without associated psychiatric history. In both cases, the use of low-dose (25 mg) sertraline taken at bedtime resulted in immediate, full and sustained resolution of symptoms at the latest follow-ups. The sertraline efficacy was of particular benefit for the patient reported on in case 2 who was a commercial airline pilot subjected to a highly restricted list of Federal Aviation Administration-approved medications. Risk factors for SRED included smoking cessation and work-related stress in case 1, and a history of sleepwalking and work-related circadian disruptions and partial sleep deprivations in case 2. Sertraline therapy of SRED is considered within a review of all current pharmacologic therapies of SRED.

The safety of electroconvulsive therapy in patients with severe aortic stenosis.

Little is known about the safety of electroconvulsive therapy (ECT) in patients with severe aortic stenosis and depression and other psychiatric syndromes. We conducted a retrospective review of the medical records of 10 patients with severe aortic stenosis who underwent ECT at Mayo Clinic, Rochester, MN, between January 1, 1995, and June 30, 2006. Of the 10 patients, 6 (60%) were women. The median age was 79.5 years (range, 65-93 years). All patients had an aortic valve area of 1.0 cm2 or less (median, 0.9 cm2). The median aortic transvalvular pressure gradient was 43.5 mm Hg (range, 32-58 mm Hg). The 10 patients underwent a total of 144 ECT sessions (range, 1-37 sessions per patient). Despite this large number of sessions, only 2 patients experienced single episodes of blood pressure perceived to be low 1 minute after an electroshock; these episodes were successfully treated. Hypertensive systolic blood pressure (Greater than 180 mm Hg) and tachycardia (greater than 100 beats/min) in response to ECT prompted treatment in 7 patients during 70 ECT sessions (49%). None of the patients died within 24 hours after dismissal from the postanesthesia care unit (95% confidence interval for death rate per person, 0%-26%). Hence, ECT was safe in 10 patients with severe aortic stenosis treated at our institution. Our findings may be informative to clinicians who manage the care of patients with severe aortic stenosis who are undergoing ECT.

Total sleep time obtained from actigraphy versus sleep logs in an academic sleep center and impact on further sleep testing.

BACKGROUND: While actigraphy has been deemed ideal for the longitudinal assessment of total sleep time (TST) by select groups, endorsement has not been universal and reimbursement is lacking, preventing its widespread use in clinical practice. This study compares longitudinal TST data obtained by actigraphy and logs preceding a clinical evaluation, and secondarily ascertains whether longitudinal TST impacts clinicians' decisions to proceed with further sleep testing. METHODS: This was a retrospective, consecutive chart review spanning about 4 months in an academic sleep center. Eighty-four patients wore actigraphs in anticipation of clinical evaluations. Concomitant completion of sleep logs is routinely requested in this setting. Longitudinal TST data available in complete form was reviewed in a blinded fashion among a subset of these patients. A review of text from clinical notes of an expanded cohort with complete actigraphy data (regardless of the degree of completion of logs) enabled determination of the frequency and rationale for cancellation of prescheduled sleep testing. RESULTS: Of 84 actigraphy recordings, 90% produced complete data, and 30% produced fully completed logs. Among the subset with both available in complete form, significant mean TST differences were observed on weekends (7.06 ± 2.18 hours versus 8.30 ± 1.93 hours, P = 0.009), but not on weekdays (7.38 ± 1.97 hours versus 7.72 ± 1.62 hours, P = 0.450) for actigraphy and logs, respectively. Further analyses revealed poor agreement between the two measures, with predominantly increased TST estimation with logs. Among those with complete actigraphy data (±logs), testing was cancelled in 11 (15%), eight of whom (73%) presented with hypersomnia and three of whom (27%) presented with insomnia. Determination of insufficient sleep time was cited as the primary reason for cancellation (64%). CONCLUSION: Actigraphy and sleep logs provided discrepant mean TST data on weekends only, and the latter predominantly estimated increased TST. Actigraphy was completed more reliably than logs. Longitudinal TST information influenced clinicians' decisions to proceed with further testing, particularly among patients presenting with hypersomnia.

Maxillomandibular advancement in the management of obstructive sleep apnea.

Maxillomandibular advancement (MMA) is a surgical option for obstructive sleep apnea (OSA). MMA involves forward-fixing the maxilla and mandible approximately 10 mm via Le Fort I maxillary and sagittal split mandibular osteotomies. We retrospectively reviewed outcomes from 24 consecutive OSA patients who underwent MMA at our institution. MMA resulted in an 83% reduction in the group mean apnea-hypopnea index (AHI) per polysomnography an average of 6.7 months after surgery. Forty-two percent of patients achieved a post-MMA AHI of less than 5 events/hour sleep and 71% achieved an AHI less than or equal to 10 events/hour sleep. The Epworth Sleepiness Scale score decreased by an average of 5 post-surgery. No parameters predictive of cure for OSA by MMA were identified.

Electrode placement and ictal EEG indices in electroconvulsive therapy.

The authors determine whether quantitative electroencephalography (EEG) indices in electroconvulsive therapy (ECT) seizures correlate with stimulus electrode placement. The authors analyzed data from ECT seizures involving three electrode placements on 37 different quantitative EEG measures. Though there were a few statistically significant comparisons, no consistent pattern of differences was discerned among the three electrode placements. Though many different EEG analytical indices are available on modern ECT machines, the clinical or neurophysiologic relevance has yet to be established. These data provide a groundwork for future research on the neurophysiological aspects of ECT.
