From posts to protection: Ethical considerations regarding forensic psychiatrists and a duty to warn based on social media.

Increasing use of social media in forensic mental health evaluations will lead to new challenges that must be resolved by forensic practitioners and the legal system. One such dilemma is the discovery of information that would typically trigger a legal duty and professional ethics obligation for mental health professionals to breach doctor-patient confidentiality to promote public safety and prevent harm to vulnerable third parties. Although the law and professional organizations offer clear guidance for practitioners in the treatment role, there is currently no clarity from the law or instruction from professional organizations on what mental health professionals should do if they discover such information during a confidential forensic evaluation. For example, a forensic evaluator may find evidence on social media of an evaluee's threats to seriously harm others, abuse of children and the elderly, or severely impaired driving. There are no clear guidelines for how a forensic psychiatrist should respond in these complicated situations. We review the legal concepts and historical evolution of confidentiality, privilege, and mandated reporter duties that forensic practitioners should consider in these legally ambiguous situations. Finally, we discuss ethics frameworks practitioners can implement to determine their most ethical course of action when faced with such dilemmas.

Cataract surgery using two 3D visualization systems: Complication rates, surgical duration & comparison with traditional microscopes.

PURPOSE: To compare the complication rates and surgical duration of cataract surgery using two 3D visualization systems and a traditional binocular microscope among experienced and inexperienced surgeons. METHODS: This retrospective case series included 571 eyes that received cataract surgery using either heads up cataract surgery, via a 3D head mounted system (N = 148-Group 1) or a 3D display screen (N = 338 eyes-Group 2), or traditional binocular microscope (N = 85 eyes-Group 3). The surgical records of consecutive patients who underwent cataract surgery by two groups of surgeons (experienced and inexperienced) were reviewed. Patients in all groups received either femtosecond laser assisted cataract surgery (FLACS) or traditional phacoemulsification. Complication rate, as well as duration of cataract surgery were evaluated between all three visualization approaches, between experienced and inexperienced surgeons. RESULTS: There was no statistically significant difference in duration of surgery between all 3 visualization approaches for both experienced and inexperienced surgeons (p < 0.05). Furthermore, the type of surgical technique (manual or FLACS) did not affect the surgical duration for both experienced and inexperienced surgeons (p < 0.05). No intraoperative complications were demonstrated in the current cohort. CONCLUSIONS: The implementation of heads up-3D visualization either through a screen or a head mounted platform for cataract surgery seems to offer similar safety and efficiency as the traditional binocular microscope, and both experienced and inexperienced surgeons demonstrate the same outcomes in terms of safety and efficiency.

Forensic neurology: a distinct subspecialty at the intersection of neurology, neuroscience and law.

Neurological evidence is increasingly used in criminal cases to argue that a defendant is less responsible for their behaviour, is not competent to stand trial or should receive a reduced punishment for the crime. Unfortunately, neurologists are rarely involved in such cases despite having the expertise to help to inform these decisions in court. In this Perspective, we advocate for the development of 'forensic neurology', a subspecialty of neurology focused on using neurological clinical and scientific expertise to address legal questions for the criminal justice system. We review literature suggesting that the incidence of criminal behaviour is higher in people with certain neurological disorders than the general public and that undiagnosed neurological abnormalities are common in people who commit crimes. We discuss the need for forensic neurologists in criminal cases to provide an opinion on what neurological diagnoses are present, the resulting symptoms and ultimately whether the symptoms affect legal determinations such as criminal responsibility or competency.

Work Intensity of Postoperative Care Following Implantation of Presbyopia-Correcting versus Monofocal Intraocular Lenses.

Purpose: To compare the work intensity of postoperative care following implantation of presbyopia-correcting intraocular lenses (IOLs) to that of standard monofocal IOLs. Patients and Methods: This open-label, multicenter, comparative study retrospectively reviewed the case records of cataract surgery patients who underwent bilateral implantation of either presbyopia-correcting IOLs (presby-IOL group; N=177) or standard monofocal IOLs (monofocal group; N=177). Outcome measures included the total time the patient spent in the office, number of visits, mean duration of visits, and the number of procedures and diagnostic tests during the first postoperative year. Outcome measures were compared between the first 90 days and days 91-365 after surgery. Results: Mean (±SD) time spent in the office during the first postoperative year was 5:50 ± 3:35 hours (H:MM) over 6.6 ± 2.9 visits in the presby-IOL group, compared to 3:38 ± 1:36 hours over 4.9 ± 1.6 visits in the monofocal IOL group (p <0.001). During the first 90 days, a presby-IOL patient spent 40 minutes longer in the office than a monofocal IOL patient (3:39 ± 1:38 hours vs 2.59 ± 1:13 hours) (p <0.001). During days 91-365, time in the office was 1:32 hours longer (p <0.001), and the mean visit duration was 8 minutes longer for the presby-IOL patients (p=0.002) than those with monofocal IOL. In addition, the presby-IOL patients underwent more procedures and diagnostic tests (p ≤0.001) as compared with standard monofocal cataract surgery patients. Conclusion: Patients implanted with presbyopia-correcting IOLs require significantly more clinic time, diagnostic testing, and procedures postoperatively as compared with standard monofocal cataract surgery patients.

Pragmatic Approaches to COVID-19 Related Ethics Dilemmas for Psychiatrists.

Psychiatrists face complex ethics dilemmas in the COVID-19 pandemic era when assessing dangerousness in patients or forensic evaluees who threaten to purposely infect others or spread the virus. Understanding local public health and medical quarantine laws for their jurisdictions can help guide treating psychiatrists in how to handle some of these situations; however, challenges occur when what is ethically best conflicts with the action that will confer the greatest protection against legal liability. Additionally, the calculus of weighing competing ethics considerations changes based on how relevant it is to the duties of a particular role (e.g., treatment, forensic, research, managed care, etc.) as well as the contextual factors of the situation. We present dialectical principlism as a framework to help psychiatrists resolve such ethics dilemmas related to the COVID-19 and future pandemics, illustrating how it can be applied in different roles (i.e., treatment versus forensic) and situations (i.e., when it is clear the danger of viral transmission is secondary to a delusion versus a delusion-like belief) to come to the best outcome that balances patient welfare, legal considerations, and societal safety. Occasionally, the most ethical action may entail small liability risks.

Real-World Experience with Intracapsular Administration of Dexamethasone Intraocular Suspension 9% for Control of Postoperative Inflammation.

Corticosteroids and non-steroidal anti-inflammatory drugs are commonly used prophylactically to control inflammation after ocular surgery. When prescribed as eye drops, as has been longstanding tradition, anti-inflammatory success is out of surgeons' hands, dependent on patient compliance and proper instillation technique. Sustained-release, intraoperatively administered anti-inflammatory drugs are emerging as another option. DEXYCU (dexamethasone intraocular suspension) 9% is the first and only intraocular corticosteroid FDA-approved for postoperative inflammation, whose sustained-release formulation provides a high initial release of drug, followed by a gradual tapering. Administration of the drug directly into the capsular bag following cataract surgery enables reliable placement proximal to target tissues, ensuring surgeon control and visibility of delivery, safety, and efficiency. This technique also minimizes contact with metabolically active tissues such as the corneal endothelium, iris, and ciliary body. In this paper, we review the available literature on dexamethasone intraocular suspension and summarize surgeons' consensus on best practices for intracapsular administration.

First Real-World, Multicenter, Post-Marketing, Retrospective Study of Dexamethasone Intraocular Suspension for Inflammation After Cataract Surgery.

Purpose: To evaluate dexamethasone intraocular suspension 9% (intraocular DXM) in real-world clinical use to manage inflammation associated with cataract surgery. Setting: Patients who underwent cataract surgery and received intraocular DXM at 22 outpatient eye surgery centers in the US. Design: Retrospective, observational chart review. Methods: Records of all patients who received intraocular DXM from March to December 2019 at participating centers were reviewed. Main Outcome Measures: Outcomes included anterior chamber cell (ACC) grades, anterior chamber flare (ACF) grades, and visual acuity, as well as intraocular pressure (IOP) and adverse events (AEs) at postoperative days (PODs) 1, 8, 14, 30. Descriptive statistics were generated. Results: The study population included 527 patients (641 eyes), with glaucoma history in 66 patients (80 eyes). Among eyes with recorded ACC grades, the percentage with grade 0 increased from 40% at POD 1 to 89.7% at POD 30, with similar results in eyes with glaucoma history. Among eyes with recorded ACF grades, the percentage with grade 0 increased from 78.4% at POD 1 to 97.1% at POD 30. At POD 30, 96.6% eyes with recorded results achieved target acuity. Mean IOP was 18.6 mmHg at POD 1 but declined to ≤15.2 mmHg thereafter. Investigators reported 22 AEs in 20 patients, all reported mild or moderate, the most common: IOP increase (7 events). Conclusion: Patients undergoing cataract surgery and treated with intraocular DXM showed favorable inflammatory and visual outcomes, without unanticipated safety problems, consistent with results of previous controlled clinical trials.

Outcomes of toric IOL implantation guided by iris-registered femtosecond laser capsulotomy markings.

PURPOSE: To assess the accuracy and stability of iris-registered femtosecond laser-assisted anterior capsule axis markings (compensating cyclotorsion) along with refractive and visual outcomes after toric IOL implantation. METHODS: This prospective case series included eyes with visually significant cataracts and regular corneal astigmatism ranging from 1.25D to 4.0D, which received FLACS and toric IOL implantation, at The Eye Institute of West Florida, Largo, Florida, USA. Preoperative iris registration was used in conjunction with a femtosecond laser platform to create cyclotorsion corrected axis marks at the capsulotomy edge to facilitate toric IOL axial alignment. Patients were examined one, seven and thirty days after surgery to assess capsulotomy marks axis, toric IOL axis along with visual and refractive outcomes. RESULTS: Eighteen eyes of 13 patients aged 74.35 ± 8.65 years were included. Mean pre-op CDVA was 0.24 ± 0.16 LogMAR, while mean post-op UDVA was 0.09 ± 0.09 LogMAR. Mean pre-op corneal astigmatism was 1.85 ± 0.41 D, decreasing to 0.24 ± 0.41 D of refractive astigmatism postoperatively (p < 0.001). The capsular toric axis markings were visible in 100% of eyes throughout the follow-up; the mean difference between intended capsulotomy mark axis and measured capsulotomy mark axis was 1.6°, 1.7° and 1.3 o at the 1, 7 and 30 day intervals (p > 0.05), respectively. No capsule-related or any other type of complications was noted. CONCLUSIONS: Iris-registered femtosecond laser-assisted anterior capsule axis markings are safe and may be considered as an alternative option to the known axis marking techniques for toric IOL axial alignment at the time of cataract surgery.

Argentinian Flag Sign and Its Management during Femtosecond Laser-Assisted Cataract Surgery in a Case with Intumescent Cataracts.

We describe a case of radial extension and its management during femtosecond laser-assisted cataract surgery (FLACS) in a patient with intumescent cataracts. Radial extension was observed after injection of trypan blue into the anterior chamber. Management of the extension was achieved by separation of adhesions between the incomplete capsulotomy, along with manual completion at the areas of extensions. Careful observation during FLACS capsulotomy is advised in cases of intumescent cataracts due to the release of cortex into the anterior chamber which may interfere with the delivery of the laser treatment resulting in incomplete capsulotomy patterns. Furthermore, trypan blue staining is essential to identify possible incomplete capsulotomy patterns and extensions. The Argentinian flag sign may occur after femtosecond laser-assisted capsulotomy in cases of intumescent cataracts. Proper identification of incomplete capsulotomy patterns and radial extensions should be managed with careful manual completion of the capsulotomy.

Voluntary intoxication, homicide, and mens rea: Past, present, and future.

Voluntary, or intentional, acute intoxication does not qualify for an insanity defense. However, in many jurisdictions, voluntary intoxication can create a diminished capacity to form a specific intent necessary for a criminal offense. This is a type of mens rea defense. Homicide provides a clear example where the absence of a required specific intent can lead to a lesser included crime that does not require that specific intent. Thereby, a mens rea defense may lessen a first-degree murder charge to a lesser degree or even manslaughter, depending on the jurisdiction. After reviewing the history of mens rea defenses and voluntary intoxication, we performed a search of LexisNexis for state statutes and case law regulating the use of voluntary intoxication in mens rea defenses, focusing on homicide-related offenses. In this article, we compare the different approaches that have developed to address this complex issue. We discuss why knowledge of these different approaches is essential to the practicing forensic examiner in relevant jurisdictions and explore developing issues in the area.

Comparative Assessment of Ergonomic Experience with Heads-Up Display and Conventional Surgical Microscope in the Operating Room.

PURPOSE: Musculoskeletal pain issues are prevalent in ophthalmic surgeons and can impact surgeon well-being and productivity. Heads-up displays (HUD) can improve upon conventional microscopes by reducing ergonomic stress. This study compared ergonomic outcomes between HUD and a conventional optical microscope in the operating room, as reported by ophthalmic surgeons in the US. METHODS: An online questionnaire was distributed to a sample of surgeons who had experience operating with HUD. The questionnaire captured surgeon-specific variables, the validated Nordic Musculoskeletal Questionnaire, and custom questions to compare HUD and conventional microscope. A multivariable model was built to identify variables that were likely to predict improvement in pain-related issues. RESULTS: Analysis was conducted on 64 surgeons (37 posterior-segment, 25 anterior-segment, and two mixed) with a mean 14.9 years of practice and 2.3 years using HUD. Most surgeons agreed or strongly agreed that HUD reduced the severity (64%) and frequency (63%) of pain and discomfort, improved posture (73%), and improved overall comfort (77%). Of respondents who experienced headaches, or pain and discomfort during operation, 12 (44%) reported their headaches improved and 45 (82%) reported feeling less pain and discomfort since they started using HUD. The multivariable model indicated the odds of reporting an improvement in pain since introducing the HUD in the operating room were 5.12-times greater for those who used HUD in >50% of their cases (P=0.029). CONCLUSION: This study indicates that heads-up display may be an important tool for wellness in the operating room as it can benefit ophthalmic surgeons across several ergonomic measures.

Heads-up Cataract Surgery: Complication Rates, Surgical Duration, and Comparison With Traditional Microscopes.

PURPOSE: To compare the complication rates and surgical duration between a three-dimensional visualization system (heads-up surgery) and traditional binocular microscope in cataract surgery. METHODS: This retrospective case series included 2,320 eyes that received cataract surgery using either a three-dimensional display system (n = 1,673 eyes) (3D group) or a traditional binocular microscope (n = 647 eyes) (traditional group). The medical records of consecutive patients who underwent cataract surgery by a single surgeon in The Eye Institute of West Florida from August 2016 to July 2017 using either a three-dimensional display system or the traditional binocular microscope for visualization were reviewed. Patients in both groups received either femto-second laser-assisted cataract surgery (FLACS) or traditional phacoemulsification. Complication rate (posterior capsular rapture and vitreous prolapse) and duration of cataract surgery were evaluated. RESULTS: The 3D group had 12 (0.72%) complications and the traditional group had 5 (0.77%) complications (P > .05). Mean surgical time was 6.48 ± 1.15 minutes for the 3D group and 6.52 ± 1.38 minutes for the traditional group (P > .05). There was no statistically significant difference in complication rate and duration of surgery between the two groups (P > .05). CONCLUSIONS: The implementation of heads-up three-dimensional visualization for cataract surgery seems to offer similar safety and efficiency as the traditional binocular microscope.

The Effect of NSAID Pretreatment on Aqueous Humor Prostaglandin E2 Concentration in Eyes Undergoing Femtosecond Laser-Assisted Capsulotomy.

PURPOSE: To assess aqueous humor concentration of prostaglandin E2 (PGE2) after capsulotomy creation using a femtosecond laser (FLAC) in patients pretreated with short-term topical ketorolac versus patients without pretreatment. METHODS: This prospective study comprised consecutive patients scheduled to undergo cataract surgery using a femtosecond laser platform to perform only capsulotomies. An identical protocol for preoperative mydriasis was used for all the eyes included in the study, while aqueous humor was extracted from the anterior chamber of all patients immediately after the initial side port incision. ELISA was performed to quantify aqueous humor PGE2. The patients were divided into 2 groups; in group 1, the patients received short-term topical ketorolac preoperatively, while the patients in group 2 did not receive NSAID pretreatment. RESULTS: Twenty eyes of 20 patients were included in the study (10 eyes in each group). Mean concentration of aqueous humor PGE2 after FLAC was 392.16 ± 162.00 pg/ml and 622.63 ± 331.84 pg/ml for groups 1 and 2, respectively. A statistically significant difference in aqueous humor PGE2 concentration between the two groups (p < 0.05) was demonstrated, with the eyes that received ketorolac pretreatment demonstrating a lower concentration of PGE2. CONCLUSION: Short-term topical use of ketorolac prior to FLAC seems to prevent excessive release of PGE2 in the anterior chamber of the eyes that received NSAID pretreatment when compared to the eyes that did not receive NSAIDs preoperatively.

Crystalline lens endocapsular fragmentation using an elastic loop filament.

PURPOSE: To describe a novel mechanical endocapsular fragmentation technique of the crystalline lens during cataract surgery using a loop elastic-thin filament. METHODS: An alternative method to mechanically fragment the crystalline lens utilizing a nitinol loop is described. This device achieves lens sectioning in multiple pieces, decreasing ultrasonic energy expenditure during cataract surgery. RESULTS: Endocapsular fragmentation of crystalline lens was achieved using a nitinol loop filament, without the use of ultrasound energy. CONCLUSION: This surgical technique demonstrates that a micro loop filament may be used as an alternative surgical approach for energy-free mechanical endocapsular nucleus disassembly and fragmentation.

Cyclorotation during femtosecond laser-assisted cataract surgery measured using iris registration.

PURPOSE: To assess ocular cyclorotation of eyes having femtosecond laser-assisted cataract surgery using iris registration. SETTING: Eye Institute of West Florida, Largo, Florida, USA. DESIGN: Retrospective cases series. METHODS: Charts of patients who had femtosecond laser-assisted cataract surgery with preoperative and intraoperative iris registration in 1 or 2 eyes between November 2015 and March 2016 were reviewed. Cyclorotation was assessed via iris-registration acquired preoperatively using the Cassini topographer (patient in upright position) and intraoperatively using the iris registration option of the Lensar laser system (patient in supine position) acquired immediately before the laser treatment. RESULTS: The study comprised 241 patients (337 eyes). The mean age of the 107 men and 134 women was 68.0 years ± 9.0 (SD) (range 37 to 90 years). The mean absolute value of cyclorotation was 5.81 ± 4.20 degrees (range 0 to 17 degrees), which was statistically significant when comparing the preoperative axis with the intraoperative axis deviation (P < .0001). Overall, incyclorotation (67.4%) was more common than excyclorotation (30.9%). In patients having bilateral femtosecond laser-assisted cataract surgery, bilateral incyclorotation (47.37%) was the most common occurrence. CONCLUSIONS: During femtosecond laser-assisted cataract surgery, clinically significant cyclotorsion that might influence astigmatism correction outcomes can occur in patients having cataract extraction. Iris registration was useful in accounting for cyclorotation during this procedure when corneal or intraocular lens-based forms of astigmatic corrections will be used.

Dysfunctional tear syndrome: dry eye disease and associated tear film disorders - new strategies for diagnosis and treatment.

Dysfunctional tear syndrome (DTS) is a common and complex condition affecting the ocular surface. The health and normal functioning of the ocular surface is dependent on a stable and sufficient tear film. Clinician awareness of conditions affecting the ocular surface has increased in recent years because of expanded research and the publication of diagnosis and treatment guidelines pertaining to disorders resulting in DTS, including the Delphi panel treatment recommendations for DTS (2006), the International Dry Eye Workshop (DEWS) (2007), the Meibomian Gland Dysfunction (MGD) Workshop (2011), and the updated Preferred Practice Pattern guidelines from the American Academy of Ophthalmology pertaining to dry eye and blepharitis (2013). Since the publication of the existing guidelines, new diagnostic techniques and treatment options that provide an opportunity for better management of patients have become available. Clinicians are now able to access a wealth of information that can help them obtain a differential diagnosis and treatment approach for patients presenting with DTS. This review provides a practical and directed approach to the diagnosis and treatment of patients with DTS, emphasizing treatment that is tailored to the specific disease subtype as well as the severity of the condition.

Review of Top 10 Prescribed Drugs and Their Interaction with Dental Treatment.

The proportion of people over age 60 is growing faster than any other group. Many patients take several medications to manage multiple chronic medical conditions. Poor oral health is common and dental visits by patients over the age of 65 are increasing. The dentist must recognize that these medications may interact with dental treatment. This article reviews the top 10 prescribed drugs as listed in the IMS Institute national prescription audit in January 2015 and reviews the interactions between these medications and dental treatment. The medications reviewed include levothyroxine, acetaminophen/hydrocodone, lisinopril, metoprolol, atorvastatin, amlodipine, metformin, omeprazole, simvastatin, and albuterol.
