An Empirical Evaluation of Eye Movement Desensitization and Reprocessing (EMDR) with Survivors of a Natural Disaster

Controlled studies of treatments effective with victims of natural disasters are almost nonexistent. This is a small study conducted under difficult conditions to test the effectiveness of Eye Movement Desensitization and Reprocessing (EMDR) in treating trauma related reactions following Hurricane Andrew. The results were positive in that EMDR produced significant improvement over wail list controls in perceived posttraumatic avoidance behaviors and thoughts as measured by changes in the Impact of Event Scale and significant improvement in subjective aversive reactions to representative experiences of the hurricane. These results suggest and support other studies that EMDR can be an effective therapeutic intervention for trauma reactions.     

Sever-L'Episcopo transfers in obstetrical palsy: a retrospective review of twenty cases

Since 1963, 25 patients have undergone Sever-L'Episcopo transfers for obstetrical birth palsy at the St. Louis Unit of the Shriners Hospital for Crippled Children. A follow-up of 2-6 years was possible with a retrospective review of 16 patients. Substantial improvement in shoulder external rotation as well as subjective functional improvement was obtained by all patients. Three transient and one permanent axillary nerve palsies resulting from this procedure are reported.     

Comparison of detection of antibody to the acquired immune deficiency syndrome virus by enzyme immunoassay, immunofluorescence, and Western blot methods.

There was 100% agreement between enzyme immunoassay (EIA) (Abbott Laboratories), Western blot, and indirect immunofluorescence (IF) when these three methods were used to measure antibody to the acquired immune deficiency syndrome (AIDS) virus in sera from 142 high-risk individuals, indicating that IF was a sensitive alternative method for detecting antibody to this agent. Thirty-two (64%) of 50 EIA-positive plasma specimens from a blood bank and 6 (21%) of 28 EIA-positive sera from alternative testing sites were negative by IF. In addition, two EIA-negative sera from the latter group were positive by IF. Western blotting agreed with IF on those 40 specimens which gave discrepant results by EIA and IF. The IF method was determined to be equal to Western blotting in sensitivity and specificity for detection of AIDS antibody, and it was found to be useful for confirming positive EIA results, especially in specimens from individuals in low-risk groups.     

A noradrenergic and serotonergic hypothesis of the linkage between epilepsy and affective disorders

Noradrenergic and/or serotonergic deficits, as well as other abnormalities, may contribute to predisposition to some epilepsies and depressions. Evidence for this hypothesis stems from several sources. Epidemiological investigations are intriguing but incomplete. Pharmacological studies show that noradrenergic and/or serotonergic transmission are both anticonvulsant and antidepressant. Therapeutically pertinent investigations show that antidepressant drugs have anticonvulsant properties, whereas antiepileptic drugs are effective in the management of affective disorders. Additional investigations demonstrate that seizures, whether spontaneously occurring or therapeutically induced, protect against depression. Through studies of innate pathophysiology, noradrenergic and serotonergic deficits have been identified in individuals with depression and in animal models of epilepsy, as well as in some humans with epilepsy. Vagal nerve stimulation, a treatment already known to be effective in the epilepsies, is presently under investigation for effectiveness in affective disorder. New evidence suggests that vagal nerve stimulation exerts at least some of its therapeutic effects through its capacity to increase noradrenergic and serotonergic transmission. Finally, emerging evidence supports the concept that some genetic mammalian models of the human epilepsies exhibit analogous manifestations of depression.     

Transconjunctival frontalis suspension (TCFS).

We have devised a frontalis suspension technique originally described in an article entitled, "Transconjunctival frontalis suspension for blepharoptosis" (Trans Am Acad Ophthal Otolaryngol 83:684-92), by Swan and Tongue in 1977. This modified transconjunctival frontalis suspension (TCFS) procedure is described. It has been used at the Oregon Health Sciences University in its original or modified form since 1970. To better understand how this procedure successfully corrects blepharoptosis in patients with poor levator function, a study was undertaken to discern the anatomic relationship of the suspension material to important ocular adnexal structures. The findings are based on gross anatomic dissection and histologic examination of a cadaver eyelid after postmortem transconjunctival fascia lata frontalis suspension. The distal, horizontal limb of the fascia suspends the central portion of the levator aponeurosis in a hammock-type fashion. The two vertical limbs pierce the aponeurosis at the level of Whitnall's ligament and incorporate this ligament. The fascia then exits the orbit through the orbital septum near the arcus marginalis and is incorporated into the frontalis muscle near the junction of the medial one-third and lateral two-thirds of the brow, temporal to the supraorbital neurovascular bundle. This anatomic location is not only relatively easily and safely attained, but also maximizes the principles of more traditional frontalis suspensions while minimizing the effort and surgical manipulation.     

Selective radiofrequency ablation of the slow pathway for the treatment of atrioventricular nodal reentrant tachycardia. Evidence for involvement of perinodal myocardium within the reentrant circuit.

BACKGROUND. The circuit of atrioventricular (AV) nodal reentrant tachycardia may include perinodal atrial myocardium. Furthermore, in patients with dual AV nodal pathways, the atrial insertion of the slow pathway is likely to be located near the ostium of the coronary sinus, caudal to the expected location of the AV node. The present study was designed to evaluate the safety and efficacy of selective catheter ablation of the slow pathway using radiofrequency energy applied along the tricuspid annulus near the coronary sinus ostium as definitive therapy for AV nodal reentrant tachycardia. METHODS AND RESULTS. Among 34 consecutive patients who were prospectively enrolled in the study, the slow pathway was selectively ablated in 30, and the fast pathway was ablated in four. Antegrade conduction over the fast pathway remained intact in all 30 patients after successful selective slow pathway ablation. There was no statistically significant change in the atrio-His interval (68.5 +/- 21.8 msec before and 69.6 +/- 23.9 msec after ablation) or AV Wenckebach rate (167 +/- 27 beats per minute before and 178 +/- 50 beats per minute after ablation) after selective ablation of the slow pathway. However, the antegrade effective refractory period of the fast pathway decreased from 348 +/- 94 msec before ablation to 309 +/- 79 msec after selective slow pathway ablation (p = 0.005). Retrograde conduction remained intact in 26 of 30 patients after selective ablation of the slow pathway. The retrograde refractory period of the ventriculo-atrial conduction system was 285 +/- 55 msec before and 280 +/- 52 msec after slow pathway ablation in patients with intact retrograde conduction (p = NS). There were three complications in two patients, including an episode of pulmonary edema and the development of spontaneous AV Wenckebach block during sleep in one patient after slow pathway ablation and the late development of complete AV block in another patient after fast pathway ablation. Over a mean follow-up period of 322 +/- 73 days, AV nodal reentrant tachycardia recurred in three patients, all of whom were successfully treated in a second ablation session. CONCLUSIONS. Radiofrequency ablation of the slow AV pathway is highly effective and is associated with a low rate of complications.     

Pathways to Colonoscopy in the South: Seeds of Health Disparities

Objectives. We aimed to highlight sociodemographic differences in how patients access colonoscopy.Methods. We invited all eligible patients (n = 2500) from 2 academy-affiliated colonoscopy centers in Alachua County, Florida (1 free standing, 1 hospital based), to participate in a precolonoscopy survey (September 2011–October 2013); patients agreeing to participate (n = 1841, response rate = 73.6%) received a $5.00 gift card.Results. We found sociodemographic differences in referral pathway, costs, and reasons associated with obtaining the procedure. Patients with the ideal pathway (referred by their regular doctor for age-appropriate screening) were more likely to be Black (compared with other minorities), male, high income, employed, and older. Having the colonoscopy because of symptoms was associated with being female, younger, and having lower income. We found significant differences for 1 previously underestimated barrier, having a spouse to accompany the patient to the procedure.Conclusions. Patients’ facilitators and barriers to colonoscopy differed by sociodemographics in our study, which implies that interventions based on a single facilitator will not be effective for all subgroups of a population.Colorectal cancer (CRC), the second leading cause of US cancer deaths in 2013 (50 830),1 is not distributed equally. Nationally, it is estimated that incidence is 25% higher, and mortality from CRC 50% higher, in Black Americans than in Whites.2,3 Most CRC diagnoses follow evaluation by colonoscopy. Although consumers have a range of CRC screening tests, from least invasive (fecal occult blood test, fecal immunochemical test) to most invasive (sigmoidoscopy, colonoscopy),4 if polyps are indicated, a colonoscopy is required as follow-up. Thus, colonoscopy is both an entry point and a pivotal event in the process of preventing, detecting, and treating CRC. CRC can be prevented through the removal of precancerous polyps or detected at an early, easily treatable stage5; findings indicate6 that colonoscopy with polypectomy reduces mortality from CRC by 53%. Although rates of CRC screening have increased,3 there is need for improvement. More than one third of Americans are not in compliance with screening guidelines,7 with rates being lower in the southern United States.8In 2008, Etzioni et al.9 presented a model of patient and provider-level factors that influence decision-making in colon cancer and that can lead to health disparities in disease recurrence and survival. The Etzioni model identifies key points of vulnerability in the treatment process where the potential to achieve high-quality, guideline-recommended care can be lost. The model captures patients after surgery, beginning with the decision to refer patients to a medical oncologist for adjuvant treatment; it is relevant because there is considerable evidence of inequities in who receives adjuvant treatment based on older age,10,11 comorbidities,12,13 low income,7 coverage with Medicaid rather than Medicare,13 Black race,14 female gender,15,16 and being unmarried.9We propose that this model starts too late in the process; health disparities originate prior to colonoscopy and can increase at each decision point along a continuum. In an elaborated model (Figure 1), we suggest that CRC health disparities research should begin with an investigation of entry into the health care system and the subsequent pathways to colonoscopy. Referral patterns, costs, and patient demographics influence patient access to care, colonoscopy compliance, and postcolonoscopy decision-making.Open in a separate windowFIGURE 1—Pathways to colonoscopy, treatment, and outcomes.
