Efficacy of Repeated Courses of Rituximab as Treatment for Pemphigus Vulgaris.

Rituximab targets the B-lymphocyte antigen CD20, providing pemphigus vulgaris patients with long-term remissions. However, the effects of repeated courses have not yet been established. This study aimed to evaluate the effect of repeated rituximab courses on remission length in pemphigus vulgaris. A total of 73 patients with pemphigus vulgaris treated with rituximab at a single centre were retrospectively analysed. Of 73 study participants (28 men, 45 women), 42 (58%) received a 2nd course of rituximab, 24 (33%) received a 3rd course, 4 (6%) received a 4th course, and one (1%) received a 5th course. Rituximab remained efficacious in each course, irrespective of previous treatments (complete remission 75-81%). Following the 2nd and 3rd courses, the results indicated longer remissions with reduced flare-ups, and the remission length increased with each subsequent course. We conclude that rituximab serves as a disease-modifying agent, notably for patients with moderate-to-severe pemphigus vulgaris.

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.

Examining the Correlation between Objective Injury Parameters, Personality Traits, and Adjustment Measures among Burn Victims.

BACKGROUND: Burn victims experience immense physical and mental hardship during their process of rehabilitation and regaining functionality. We examined different objective burn-related factors as well as psychological ones, in the form of personality traits that may affect the rehabilitation process and its outcome. OBJECTIVE: To assess the influence and correlation of specific personality traits and objective injury-related parameters on the adjustment of burn victims post-injury. METHODS: Sixty-two male patients admitted to our burn unit due to burn injuries were compared with 36 healthy male individuals by use of questionnaires to assess each group's psychological adjustment parameters. Multivariate and hierarchical regression analysis was conducted to identify differences between the groups. RESULTS: A significant negative correlation was found between the objective burn injury severity (e.g., total body surface area and burn depth) and the adjustment of burn victims (p < 0.05, p < 0.001, Table 3). Moreover, patients more severely injured tend to be more neurotic (p < 0.001), and less extroverted and agreeable (p < 0.01, Table 4). CONCLUSION: Extroverted burn victims tend to adjust better to their post-injury life while the neurotic patients tend to have difficulties adjusting. This finding may suggest new tools for early identification of maladjustment-prone patients and therefore provide them with better psychological support in a more dedicated manner.

Microincisions in cataract surgery.

UNLABELLED: Improvements in phacoemulsification technology and instrumentation and intraocular lens materials and design have enabled cataract surgery to be performed through incisions smaller than 2.0 mm in external width. This evolution has occurred over time, with new challenges arising at each step of the decrease in incision size. This article reviews the current trend of using increasingly smaller incisions to perform phacoemulsification. Specifically, each facet of phacoemulsification is briefly reviewed from a historical context and then evaluated predominantly from a current perspective to better understand the development of the microincision in cataract surgery. The goal is to help the operating surgeon recognize the potential benefits as well as the potential weaknesses of the smaller incision.

Serious ocular complications of cosmetic iris implants in 14 eyes.

PURPOSE: To report the presentation and subsequent management of a series of patients presenting with cosmetic iris implants. SETTING: New York Eye and Ear Infirmary, New York, New York, USA. DESIGN: Case series. METHODS: In this evaluation of patients with NewColorIris cosmetic iris implants, data collected included patient demographics, visual acuity, intraocular pressure (IOP), endothelial cell count, and slitlamp examination findings at presentation. Medical and surgical interventions and the postoperative course were recorded. RESULTS: Fourteen eyes of 7 patients (ages 22 to 60; 71% men) were identified. Nine eyes (64%) presented with decreased visual acuity, 7 (50%) had elevated IOP, 5 (36%) had corneal edema, and 5 (36%) had anterior uveitis. All 14 eyes had explantation of the iris prosthesis (range 4 to 33 months after placement). The minimum follow-up after implant removal in all eyes was 2 months (range 2 to 28 months). Intraoperative complications included suprachoroidal hemorrhage during explantation in 1 eye. Postoperative complications included corneal edema (8 eyes), cataract (9 eyes), and increased IOP/glaucoma (7 eyes). Secondary surgeries included Descemet-stripping automated endothelial keratoplasty (5 eyes), cataract extraction with intraocular lens placement (7 eyes), trabeculectomy (3 eyes), glaucoma drainage implant placement (3 eyes), and penetrating keratoplasty (1 eye). CONCLUSIONS: The cosmetic iris implants may result in severe ocular morbidity. Complications in our series included uveitis, glaucoma, corneal edema, and decreased visual acuity. Although explantation helped stabilize symptoms, additional medical and surgical intervention to control IOP and corneal decompensation was required in many cases.

Role of Orbscan II in screening keratoconus suspects before refractive corneal surgery.

OBJECTIVE: To evaluate the relationship between videokeratographic keratoconus screening programs and Orbscan II topography. DESIGN: Prospective, observational case series and instrument validation study. PARTICIPANTS: Sixty consecutive eyes with suspicious videokeratography (TMS-1, Tomey Technology, Waltham, MA) were evaluated before undergoing laser in situ keratomileusis (LASIK) surgery. A control group of 50 consecutive eyes without suspicious features by videokeratography was also evaluated. METHODS: Keratoconus screening programs, using the Rabinowitz and Klyce/Maeda methods and Orbscan II (Bausch & Lomb, Claremont, CA) topographies were performed on these patients. MAIN OUTCOME MEASURES: Specific parameters evaluated on the Orbscan II topographies were anterior elevation, posterior elevation, and thinnest pachymetry. RESULTS: Compared with a control group of patients without suspicious videokeratography, there was a statistically significant difference in the mean posterior elevation and mean anterior elevation in the groups with positive keratoconus testing with the Rabinowitz or Klyce/Maeda methods. For patients who met both the Rabinowitz and Klyce/Maeda criteria for keratoconus, the mean posterior elevation was 44 +/- 2.5 micro m compared with a posterior elevation of 21 +/- 0.6 micro m for the control group. There was no statistically significant difference in the mean thinnest pachymetry between the control group and all keratoconus suspect groups. CONCLUSIONS: Patients with positive keratoconus screening tests have higher anterior and posterior elevation on Orbscan II topography. When used in combination with videokeratography, the Orbscan II topography system may be helpful in identifying patients who are potentially at high risk for developing ectasia after LASIK.
