Secondary microkeratome-induced flap interference with the pathway of the primary flap

PURPOSE: To report a flap-related complication that occurs when a secondary microkeratome pass interferes with the pathway of a complicated first microkeratome pass. DESIGN: Small, retrospective, noncomparative, interventional case series. PARTICIPANTS: Three patients. METHODS: In three cases, each patient experienced a different flap-related complication with the original surgery, followed by interference of a secondary flap with the primary. The first patient experienced a free cap, followed by an interference of the secondary flap at the nasal portion of the free cap. The second patient experienced a buttonhole, followed by secondary flap interference in the superior quadrant adjacent to the buttonhole. The third patient experienced a decentered flap originally, followed by secondary flap interference temporally. MAIN OUTCOME MEASURES: Visual result after secondary microkeratome-induced flap-related complications. RESULTS: All three patients had poor best spectacle-corrected visual acuity on the first postoperative day, with subsequent visual recovery. All three patients had induced flattening on keratometry along the axis where stromal tissue was removed. In addition, two patients required multiple enhancements to achieve desired visual outcomes. CONCLUSIONS: Complications related to the primary microkeratome pass add further risk for complications to arise during a second microkeratome pass. A secondary microkeratome pass should be attempted only if the original flap cannot be identified, if it is the result of primary flap complication, or if the desired treatment zone is notably larger than the diameter of the original flap. Intraoperative pachymetry of the residual stromal bed should be performed routinely. It is important to examine the stromal bed closely for loose or displaced slivers of tissue and to remove them before excimer treatment.     

Usefulness of Transesophageal Echocardiography in Diagnosing Valve Leakage of Left Ventricular Assist Device

In this case report, we present the utility of transesophageal echocardiography in the detection of two uncommon complications of left ventricular assist devices: regurgitation of the bioprosthetic valve in the inflow conduit and a tear of a Dacron conduit with hematoma formation and compression of the right ventricular free wall.     

Meeting employees where they are: The rise of workplace mental health services

Many key organizations have called attention to the importance of addressing workplace mental health. In this Open Forum piece, two academic psychiatrists present recommendations from their experiences providing psychiatric care in a corporate setting. A literature review using the PubMed database was performed. The search found no peer review articles that discuss the topic of employer-sponsored mental health services outside of traditional employee assistant programs. Based on first-hand experience, the authors of this forum describe key issues and best practices to ensure employer-sponsored mental health services are a successful treatment for patients and mental health providers alike.     

Live/Real Time Three‐Dimensional Transthoracic Echocardiography in the Evaluation of Post Traumatic Acquired Thoracic Aortic Coarctation

We report a young patient with post traumatic acquired thoracic aortic coarctation in whom three‐dimensional transthoracic echocardiography (3DTTE) demonstrated incremental value over two‐dimensional transthoracic echocardiography (2DTTE). 3DTTE showed (1) en face views of the obstruction site that showed a markedly narrowed, roughly circular orifice measuring 0.33 cm² in area, (2) echogenic tissue encroaching on the graft lumen consistent with fibrosis/thrombus, and (3) no graft protrusion into the aortic lumen, only hypermobility of the medial portion of the graft. These important findings were not detected by 2DTTE. (Echocardiography 2010;27:470‐472)     

Augmentation–Mastopexy Using an Autologous Parenchymal Sling

Background  

Mastopexy–augmentation is an important treatment to address breast deflation. Combining these two procedures is technique-sensitive, with a reported high revision rate and propensity for complications. We describe an approach to achieve aesthetic breast correction in an effective, reproducible, and safe manner while minimizing untoward sequela.     

Associations Between Abortion Services and Acceptance of Postabortion Contraception in Six Indian States

Women receiving induced abortions or postabortion care are at high risk of subsequent unintended pregnancy, and intervals of less than six months between abortion and subsequent pregnancy may be associated with adverse outcomes. This study highlights the prevalence and attributes of postabortion contraceptive acceptance from 2,456 health facilities in six major Indian states, among 292,508 women who received abortion care services from July 2011 through June 2014. Eighty‐one percent of the women accepted postabortion contraceptive methods: 53 percent short‐term, 11 percent intrauterine devices, and 16 percent sterilization. Postabortion contraceptive acceptance was highest among women who were aged 25 years and older, received first‐trimester services, received induced abortion, attended primary‐level health facilities, and had medical abortions. Doctors receiving post‐training support were more likely to offer contraceptives, but no association was observed between such support and acceptance of IUDs or sterilization. Comprehensive service‐delivery interventions, including ensuring availability of skilled providers and contraceptive commodities, offering clinical mentoring for providers, identifying and addressing provider bias, and improving provider counseling skills, can increase postabortion contraceptive acceptance and reduce unintended pregnancy.     

A latent variable approach in simultaneous modeling of longitudinal and dropout data in schizophrenia trials

Dropouts impact clinical trial outcome analyses. Ignoring missing data is not an acceptable option when planning, conducting or interpreting the analysis of a clinical trial. Treatment related efficacy and safety data observed in the trial may not always be sufficient in explaining the dropouts' mechanism. Nevertheless, these dropout data may carry important treatment-related information and present as an outcome by itself. Traditional analyses involve the use of the time-to-event approach assuming that the dropouts' hazard is solely related to the efficacy or safety profiles observed in a study. A latent variable approach was developed to generalize this approach and to implement a more flexible dropout hazard function in a schizophrenia trial. This unobserved latent variable was used to jointly model the longitudinal efficacy data and dropout profiles across treatments. The analysis provides a framework to model informative dropouts simultaneously with primary efficacy outcomes and make intelligent decisions in drug development.
