XEN Glaucoma Implant with Mitomycin C 1-Year Follow-Up: Result and Complications

Purpose. To evaluate gel microstent (XEN, Aquesys, Inc) for treatment of primary open angle glaucoma (POAG). Methods. In this prospective interventional study, 13 eyes with POAG underwent XEN implantation with subconjunctival mitomycin-C. Of those eyes, 3 were pseudophakic and 10 underwent simultaneous phacoemulsification and XEN. Patients had uncontrolled IOP, had intolerance to therapy, or had maximal therapy but undergoing cataract extraction. Follow-up visits included IOP, number of medications, vision, and complications and lasted for 1 year. Complete success was defined as IOP reduction ≥20% from preoperative baseline at 1 year without any glaucoma medications while partial success as IOP reduction of ≥20% at 1 year with medications. Results. IOP dropped from 16 ± 4 mmHg pre-op to 9 ± 5, 11 ± 6, 12 ± 5, 12 ± 4, and 12 ± 3 mmHg at 1 week, 1, 3, 6, and 12 months (p=0.004, 0.026, 0.034, 0.01, and 0.01, Wilcoxon Signed Ranks) consecutively. BCVA (LogMAR) was 0.33 ± 0.34 and improved to 0.13 ± 0.11 at 1 year. Mean number of medications dropped from 1.9 ± 1 preoperatively to 0.3 ± 0.49 (p=0.003) at 1 year. 42% of eyes achieved complete success and 66% qualified success. Complications included choroidal detachment in 2 eyes, and implant extrusion in 1 eye, and 2 eyes underwent trabeculectomy. Conclusion. XEN implant is an effective surgical treatment for POAG, with significant reduction in IOP and glaucoma medications at 1 year follow-up

Treatment Algorithm in Proliferative Diabetic Retinopathy - From Protocols to the Real World

Diabetes mellitus is a global epidemic that leads to multiple macrovascular and microvascular complications. The complex interrelated pathophysiological mechanisms triggered by hyperglycemia underlie the development of diabetic retinopathy (DR). Proliferative diabetic retinopathy (PDR) is a microvascular complication, considered the main cause of irreversible blindness in patients of productive age in the world. On the other hand, diabetic macular edema (DME) remains the clinical feature most closely associated with vision loss. In general, both manifestations are due to an increase in inflammatory factors, such as specific pro-inflammatory prostaglandins, interleukins and angiogenic substances including vascular endothelial growth factor (VEGF). Laser photocoagulation and VEGF inhibitors have been shown to be effective in the treatment of PDR and DME. Currently, randomized protocols suggest that VEGF inhibitors therapy could displace laser photocoagulation in the treatment of PDR with and without the presence of DME. The ongoing discussion still prevails about the different treatment modalities for both retinal manifestations in real-world settings

Neurosurgery training camp for medical student: experience of the Turkish neurosugery academy and Bursa Uludag University

IntroductionTo highlight the importance of hands-on experiences and mentorship in shaping the future workforce of specialized medical professionals via a Neurosurgery Training Camp.MethodsResponses of the questionnaire regarding the Neurosurgery Training Camp organized by Bursa Uludag University's Faculty of Medicine and the Turkish Neurosurgery Academy were reviewed retrospectively. A one-day program was organized to introduce neurosurgery to medical students. During the camp, the students participated in interactive presentations delivered by faculty members, had lunch together, became acquainted with neurosurgical tools and technologies, and performed interventions. With pre and postworkshop questionnaire, student's expectations and thoughts about camp was evaluated.ResultsForty-one students from 10 medical schools, spanning every year of study, attended the camp. Approximately 39% of the attendees (n = 16) were women and 61% (n = 25) were men. The post-workshop survey results demonstrated that 73% of the students (n = 30) were inclined to pursue a career in neurosurgery after the camp, 21.9% (n = 9) remained undecided, and 4.8% (n = 2) chose not to pursue neurosurgery. Feedback from the post-workshop questionnaire highlighted that all students perceived the camp as beneficial in providing insights into their future careers and aiding in making a decision regarding their career paths.DiscussionThe neurosurgical training camp effectively inspired and educated medical students about the discipline of neurosurgery. Furthermore, the camp effectively altered the career aspirations and perceptions of neurosurgery among the participating students

Expanding the clinical and immunological phenotypes of PAX1-deficient SCID and CID patients

Paired box 1 (PAX1) deficiency has been reported in a small number of patients diagnosed with otofaciocervical syndrome type 2 (OFCS2). We described six new patients who demonstrated variable clinical penetrance. Reduced transcriptional activity of pathogenic variants confirmed partial or complete PAX1 deficiency. Thymic aplasia and hypoplasia were associated with impaired T cell immunity. Corrective treatment was required in 4/6 patients. Hematopoietic stem cell transplantation resulted in poor immune reconstitution with absent naïve T cells, contrasting with the superior recovery of T cell immunity after thymus transplantation. Normal ex vivo differentiation of PAX1-deficient CD34+ cells into mature T cells demonstrated the absence of a hematopoietic cell-intrinsic defect. New overlapping features with DiGeorge syndrome included primary hypoparathyroidism (n = 5) and congenital heart defects (n = 2), in line with PAX1 expression during early embryogenesis. Our results highlight new features of PAX1 deficiency, which are relevant to improving early diagnosis and identifying patients requiring corrective treatment

Pharmaceutics

The purpose of this study is to evaluate the visual acuity (VA) gain profiles between patients with drug-naive diabetic macular edema (DME) treated by dexamethasone implant (DEX-implant) and assess the baseline anatomical and functional factors that could influence the response to the treatment in real-life conditions. A retrospective, multi-center observational study included 129 eyes with drug-naive DME treated by DEX-implant. The Median follow-up was 13 months. Two groups of VA gain trajectories were identified-Group A, with 71% (n = 96) of patients whose average VA gain was less than five letters and Group B, with 29% (n = 33) of patients with an average gain of 20 letters. The probability of belonging to Group B was significantly higher in patients with baseline VA \textbackslashtextless 37 letters (p = 0.001). Ellipsoid zone alterations (EZAs) or disorganization of retinal inner layers (DRILs) were associated with a lower final VA (53.0 letters versus 66.4, p = 0.002) but without a significant difference in VA gain (4.9 letters versus 6.8, p = 0.582). Despite a low baseline VA, this subgroup of patients tends to have greater visual gain, encouraging treatment with DEX-implant in such advanced-stage disease. However, some baseline anatomic parameters, such as the presence of EZAs or DRILs, negatively influenced final vision

Risk Factors for COVID-19 Associated Mucormycosis: The Ophthalmologist’s Perspective

The COVID-19 pandemic has led to a dramatic rise in the incidence of rhino-orbito-cerebral mucormycosis (ROCM) in India. The purpose of our report is to describe the prevalence of ROCM in the context of SARS-CoV-2 infection during the second Indian COVID-19 wave, as well as its diagnostics proceeding, and to discuss the challenges met in the time frame from the suspected diagnosis to the therapeutic decision in such patients. We conducted a retrospective multicentre case series study at six centres of Sudhalkar and Raghudeep group of hospitals in India. ROCM was confirmed in 38 (2.5%) of the 1546 patients admitted with SARS-CoV-2 infection. The average time to establish a diagnosis was 16 days. In total, 19 (50%) patients suffered from type 2 diabetes and were mostly treated with hypoglycaemic agents (in 90% of cases). The standard of care for SARS-CoV-2 management included systemic steroids therapy, intravenous remdesivir for 5 days, and concomitant prophylactic antibiotic therapy following admission. The median (IQR) blood glucose levels in all patients during the course of hospitalisation was 320 (250.5–375) mg/dl. A total of 16% of patients had an irreparable functional loss, and the mortality was 5%. We may hypothesise that excessive administration of antibiotics that profoundly affects human microbiota, coupled with poorly controlled glycaemia and unprotocolised haphazard steroid administration, contribute to a favourable setting for mucormycosis infections

Minimal surgery for tractional retinal detachment secondary to branch retinal vein occlusion: a case report

Abstract Background Tractional retinal detachment secondary to retinal vein occlusion is a complex entity that can be extremely difficult to manage due to an intricate association of the retinal tissue with the fibrovascular proliferation, making vitreous dissection an extraordinarily difficult procedure. Minimal surgery without endo-tamponade can reduce recovery time and avoid complications of surgery, which in some cases can lead to blindness and even phthisis. Case presentation A 64-year-old Indian woman presented with progressive worsening of vision (right eye) due to fovea involving tractional retinal detachment secondary to supero-temporal branch retinal vein occlusion. After anterior, core and peripheral vitrectomy, the epicenter of the fibrous bridge causing foveal split was identified and released. The corrected distance visual acuity improved from 6/60 pre-operatively to 6/12 post-operatively. At the 5-year follow-up, the patient remains stable both anatomically and visually. Conclusions This case illustrates how careful identification of the epicenter of traction helps maximize visual gain in patients with minimal risk of iatrogenic retinal tears and eliminates the need for endo-tamponade with either gas or silicone oil. Minimal surgery for tractional detachment provides excellent visual gains with minimal risks in select cases

A Rare Case Of Maxillary Hepatocellular Carcinoma Metastasis Mimicking Pyogenic Granuloma In A Geriatric Patient

Metastasis to the oral region is an uncommon characteristic of hepatocellular carcinoma. As such, diagnosis of these malignancies can be challenging due to clinical similarities with benign lesions. This report describes a 70-year-old woman with a rare case of oral metastasis of hepatocellular carcinoma that manifested in the anterior maxilla. The diagnosis of hepatitis Band C-related hepatocellular carcinoma was made one year before presentation to the authors' clinic. At the time of admission, the patient was undergoing medication with Sorafenib. An erythematous, haemorrhagic, painless lesion exhibited rapid growth in the maxilla over a two-month period. Based on clinical characteristics, the lesion was considered a pyogenic granuloma before pathological examination. After surgical intervention, the healing process in the eight-month follow-up period was uneventful, with no evidence of recurrence. This report highlights the importance of meticulous clinical and pathological evaluations in patients with suspected oral metastatic lesions that may mimic benign conditions.WoSScopu
