ABSTRACT
BACKGROUND: Human papillomavirus (HPV) is increasingly recognized as a significant risk factor in the development of head and neck cancers (HNCs), with varying prevalence and impact. This study aims to systematically review and analyze the prevalence of HPV in HNCs in India, providing insights into regional variations. METHODS: A comprehensive literature search was carried out using PubMed, Embase, and Web of Science up to November 10, 2023. Inclusion criteria focused on original research reporting HPV-positive cases among HNC patients in India. We used Nested-Knowledge software, for screening, and data extraction. The modified Newcastle-Ottawa Scale was used for quality assessment of included studies. We pooled the prevalence of HPV among HNC patients and performed a random-effects model meta-analysis using R software (version 4.3). RESULTS: The search yielded 33 studies, encompassing 4654 HNC patients. The pooled prevalence of HPV infection was found to be 33% (95% CI: 25.8-42.6), with notable heterogeneity (I² = 95%). Analysis of subgroups according to geographical location indicated varying prevalence rates. Specifically, the prevalence was 47% (95% CI: 32.2-62.4) in the eastern regions and 19.8% (95% CI: 10.8-33.4) in the western regions. No evidence of publication bias was detected. CONCLUSION: The observed considerable regional disparities on the prevalence of HPV in HNC patients in India emphasizes the need for integrated HPV vaccination and screening programs in public health strategies. The findings underline the necessity for further research to explore regional variations and treatment responses in HPV-associated HNCs, considering the impact of factors such as tobacco use and the potential benefits of HPV vaccination.

BACKGROUND: To discuss the impact of overactive bladder (OAB) on medical students. overactive bladder. is a chronic condition that causes sudden and intense urges to urinate, which can have significant physical and psychological effects on patients' lives. The prevalence of OAB among medical students is relatively high, with some studies reporting rates as high as 35.4%. This research aims to shed light on the prevalence rates and risk factors associated with OAB among medical students in Jordan. METHODS: A cross-sectional study was conducted using an online self-reported questionnaire as the study tool. The questionnaire collected the sociodemographic, health, and academic characteristics of medical students, as well as the new 7-item OABSS score. RESULTS: Out of the total sample of medical students surveyed (n = 525), 44.5% reported experiencing symptoms of OAB. Furthermore, the analysis also revealed that there was a significant difference in the prevalence of OAB between the ages of medical students. In addition, the study also found that there was a significant association between OAB symptoms and basic years, positive history of diagnostic UTI, positive history of recent trauma, high stress, and taking certain medications. CONCLUSIONS: The study highlights the need for further research in this area and emphasizes the possible implications of OAB for medical students, including the need for additional support and resources to manage the condition.

BACKGROUND: For healthcare delivery to be optimally effective, health systems must possess adequate levels and we must ensure a fair distribution of human resources aimed at healthcare facilities. We conducted a scoping review to map the current state of human resources for health (HRH) in India and the reasons behind its shortage. METHODS: A systematic search was conducted in various electronic databases, from the earliest available date till February 2024. We applied a uniform analytical framework to all the primary research reports and adopted the "descriptive-analytical" method from the narrative paradigm. Inductive thematic analysis was conducted to arrange the retrieved data into categories based on related themes after creating a chart of HRH problems. RESULTS: A total of 9675 articles were retrieved for this review. 88 full texts were included for the final data analysis. The shortage was addressed in 30.6% studies (n = 27) whereas 69.3% of studies (n = 61) addressed reasons for the shortage. The thematic analysis of data regarding reasons for the shortage yielded five kinds of HRH-related problems such as inadequate HRH production, job dissatisfaction, brain drain, regulatory issues, and lack of training, monitoring, and evaluation that were causing a scarcity of HRH in India. CONCLUSION: There has been a persistent shortage and inequitable distribution of human resources in India with the rural expert cadres experiencing the most severe shortage. The health department needs to establish a productive recruitment system if long-term solutions are to be achieved. It is important to address the slow and sporadic nature of the recruitment system and the issue of job insecurity among medical officers, which in turn affects their other employment benefits, such as salary, pension, and recognition for the years of service.

Artificial intelligence (AI) has shown excellent diagnostic performance in detecting various complex problems related to many areas of healthcare including ophthalmology. AI diagnostic systems developed from fundus images have become state-of-the-art tools in diagnosing retinal conditions and glaucoma as well as other ocular diseases. However, designing and implementing AI models using large imaging data is challenging. In this study, we review different machine learning (ML) and deep learning (DL) techniques applied to multiple modalities of retinal data, such as fundus images and visual fields for glaucoma detection, progression assessment, staging and so on. We summarize findings and provide several taxonomies to help the reader understand the evolution of conventional and emerging AI models in glaucoma. We discuss opportunities and challenges facing AI application in glaucoma and highlight some key themes from the existing literature that may help to explore future studies. Our goal in this systematic review is to help readers and researchers to understand critical aspects of AI related to glaucoma as well as determine the necessary steps and requirements for the successful development of AI models in glaucoma.

BACKGROUND: Spontaneous idiopathic testicular hemorrhage is an extremely rare entity with few published reports in the literature. CASE PRESENTATION: We report a case of a 15-year-old boy who had been experiencing intense, left scrotal pain for the previous twelve hours. No previous history of trauma or bleeding disorders. The left testis was enlarged and tender. Left orchiectomy was performed. The entire testis was dusty and dark grossly. Microscopic sections show diffuse intratesticular bleeding with intact seminiferous tubules and spermatogenesis. CONCLUSIONS: Spontaneous idiopathic testicular hemorrhage should be considered when evaluating patients with acute scrotal pain. Clinical and ultrasonographic findings and histopathologic evaluation are mandatory to diagnose it.

Reverse pupillary block with intraocular pressure (IOP) elevation after cataract surgery with in-the-bag implantation of intraocular lens (IOL) is considered a very rare complication. We report the case of a 47-year-old female patient with bilateral high axial myopia and posterior staphyloma presented with left acute loss of vision and eye pain, headache, and vomiting 2 weeks after uneventful presenile cataract surgery with single-piece IOL implantation in the capsular bag 1 month and 2 weeks in the right and left eyes, respectively. Gonioscopy showed extremely wide angle in all quadrants compared to the other eye with Spaeth classification of E 60c + 2 (14). Ultrasound biomicroscopy of the left eye showed epithelial corneal edema, 4.56 mm-deep anterior chamber, abnormal iris configuration with posterior concavity, and angle opening ranging between 60° and 74°, with unremarkable posterior chamber IOL and ciliary body. We managed the patient with topical antiglaucoma medications and laser peripheral iridotomy. IOP returned to normal levels. The patient was followed for 12 consecutive months. Elevated IOP from the reverse pupillary block is a rare postoperative complication of cataract surgery. It was initially described in association with the ciliary sulcus implanted IOL. Elevated IOP from the reverse pupillary block was then reported associated with scleral sutured IOLs and Yamane technique, and most recently with in-the-bag implanted 3-piece-IOL. Herein, we report the first case of pseudophakic reverse pupillary block in association with in-the-bag implanted single-piece foldable acrylic IOL.
ABSTRACT
TOPIC: To determine the cumulative incidence and features of glaucoma in Vogt-Koyanagi-Harada (VKH) syndrome patients compared to non-glaucoma patients. CLINICAL RELEVANCE: Knowing the exact burden of secondary glaucoma in VKH could guide its screening and management in clinical practice as a part of the regular follow-up for VKH patients. METHODS: The review protocol was pre-registered on PROSPERO [CRD42023462794]. PubMed, Scopus, Web of Science, EBSCOhost, and Google Scholar were searched for studies reporting the cumulative incidence and features of glaucoma presentation in VKH. A manual search was also conducted to supplement the primary search. Subgroup analyses based on glaucoma type, VKH stage, and patients' age were conducted. All analyses were conducted using STATA. Fixed- and random-effects models were selected according to the observed heterogeneity. Studies' methodological quality was determined using the NIH tool. RESULTS: The analysis of 7084 eyes revealed a progressive increase in the cumulative incidence of secondary glaucoma over time. The cumulative incidence was lowest at VKH onset (7%) and highest at 15 years (26%). Open-angle (12%; 95%CI: 9-14%) is more common than angle-closure glaucoma (7%; 95%CI: 3-13%). Glaucoma cumulative incidence is highest in the chronic recurrent stage of VKH (33%; 95%CI: 12-59%) and among children <18 years of age (26%; 95%CI: 16-37%). Features associated with glaucoma occurrence in VKH showed comparable rates to non-glaucoma cases. However, a meta-analysis to determine risk factors of glaucoma development in VKH was not feasible secondary to the lack of adjusted risk measures in included studies. Studies' quality was questionable in 5 studies. The certainty of evidence was moderate-to-high. CONCLUSION: The cumulative incidence of glaucoma increases throughout VKH's course, with a higher tendency in children, chronic recurrent stages, and long-term follow-up. Future research should focus on examining risk factors of glaucoma development in VKH through adjusted multivariable regression models.
ABSTRACT
BACKGROUND: Hypertension impacts nearly one billion individuals and is a primary health challenge. While traditional perspectives have focused on individual behavior and genetics as principal risk factors, recent research underscores the profound influence of socioeconomic factors within neighborhoods on the risk of hypertension. This systematic review and meta-analysis is aimed to elucidate the association between neighborhood deprivation and the risk of hypertension. METHODS: A comprehensive literature search was conducted across PubMed, Embase, and Web of Science from inception until December 25, 2023. Observational studies defining neighborhood deprivation and reporting hypertension incidence were included. Nested Knowledge software was used for screening and data extraction, with study quality assessed using the Newcastle-Ottawa Scale. Statistical analysis was performed with R software (V 4.3), using a random-effects model to calculate the pooled relative risk (RR). RESULTS: Twenty-six studies were included in the qualitative analysis and 22 in the meta-analysis, covering over 62 million participants. The pooled RR was 1.139 (95% CI: 1.006 - 1.290), p=0.04, indicating a higher hypertension risk in deprived neighborhoods. Subgroup analyses showed variability by country and deprivation assessment methods. RR varied from 1.00 in Japan (95% CI: 0.93-1.08) to 1.60 (95% CI: 1.07-2.39) in France and 1.57 (95% CI: 0.67-3.70) in Germany, with significant heterogeneity observed in measures of neighborhood deprivation. CONCLUSION: Our analysis confirms a significant association between neighborhood deprivation and hypertension, underscoring the importance of socioeconomic factors in public health. It highlights the need for targeted local assessments and interventions. Future research should explore the causal mechanisms and effectiveness of interventions addressing neighborhood deprivation.

PURPOSE: To review all studies reporting the occurrence of white dot syndromes (WDSs) following SARS-COV-2 infection. METHODS: On May 12, 2023, we registered our protocol on PROSPERO [registration number: CRD42023426012]. Five different databases including PubMed, Scopus, Web of Science, Google Scholar, and Science Direct were searched up to May 2023. We included all studies that reported the symptoms of WDSs following SARS-COV-2 infection. The data was extracted using a uniform Excel extraction sheet. All statistical tests were conducted with a 95% confidence interval and a 5% error margin. A p-value of less than 0.05 was considered statistically significant. The publication bias of included studies was assessed using JBI Critical Appraisal Checklist for Case Reports and IHE Quality Appraisal Checklist for Case Series studies. RESULTS: This review included thirty-two studies involving forty-eight patients. Acute macular neuroretinopathy was the most common disease (70.8%) followed by multiple evanescent white dot syndrome (14.6%) with 58.3% of WDS after their first SARS-COV-2 infection, and paracentral acute middle maculopathy (4.1%). They were mostly unilateral (56.2%). The presenting symptoms were blurred vision (70.8%), visual field disturbance (68.7%), and photopsia (20.8%). About 35.4% of the patients improved by their treatment and future complications were persistent scotoma (4.2%) and macular edema (2.1%). CONCLUSION: White dot syndromes are very rare entities. Our findings suggest a possible association between white dot syndrome onset and SARS-COV-2 infection. We recommend ophthalmologists should be aware of this suggested association to deliver better management and patients' care.
ABSTRACT
BACKGROUND: Post-traumatic stress disorder (PTSD) is increasingly recognized for its effects beyond mental health, with emerging evidence suggesting a significant association with cardiovascular diseases (CVD). This systematic review and meta-analysis aimed to synthesize available evidence on the association between PTSD and various cardiovascular outcomes. METHODS: We conducted a comprehensive literature search in databases until March 15, 2024. Studies were included if they were observational in design and assessed the association between PTSD and cardiovascular outcomes. Data were extracted on study characteristics, participant demographics, PTSD assessment, cardiovascular outcomes, and effect estimates. Meta-analyses were performed using random-effects models, and heterogeneity was assessed using the I² statistic. All statistical analyses were conducted using R software version 4.3. RESULTS: Twenty studies met the inclusion criteria, encompassing a total of over 335,000 participants. The pooled analyses demonstrated a statistically significant increased risk of any CVD (HR = 1.417, 95 % CI: 1.313-1.522), MI (HR = 1.415, 95 % CI: 1.331-1.500), and stroke (HR = 2.074, 95 % CI: 1.165-2.982) associated with PTSD. Substantial heterogeneity was observed across the studies for stroke and MACE, and evidence of publication bias was noted. CONCLUSION: This meta-analysis confirms a significant association between PTSD and an increased risk of several cardiovascular outcomes, indicating the importance of integrating cardiovascular risk management with psychiatric care for PTSD patients to mitigate the heightened risk of CVDs. Future research should focus on exploring the underlying mechanisms and potential interventions to manage both PTSD and its associated cardiovascular risks effectively.

Background: Proton pump inhibitors (PPIs) are among the most commonly prescribed medications worldwide for acid-related disorders. While their short-term efficacy and safety are well-established, concerns regarding their long-term effects on bone health have emerged. This umbrella review aimed to synthesize the available findings on the associations between PPI use and bone metabolism outcomes. Methods: An electronic search was conducted using PubMed, Web of Science, Embase, and the Cochrane Database up to September 16, 2023. Systematic reviews and meta-analyses of randomized controlled trials (RCTs) and observational studies that evaluated the relationship between PPIs and bone metabolism outcomes were included. Data extraction, quality appraisal, and synthesis were performed in line with the Joanna Briggs Institute and PRISMA guidelines. The strength of the evidence was graded using the GRADE criteria. Statistical analysis was performed in R version 4.3. Results: Out of 299 records, 27 studies met the inclusion criteria. The evidence indicated a statistically significant increased risk of fractures, notably hip, spine, and wrist fractures, in PPI users. PPI use was associated with changes in Bone Mineral Density (BMD) across various bones, though the clinical relevance of these changes remains uncertain. Furthermore, PPI-induced hypomagnesemia, which can influence bone health, was identified. A notable finding was the increased risk of dental implant failures in PPI users. However, the certainty of most of the evidence ranged from very low to low based on GRADE criteria. Conclusion: The long-term use of PPIs may be associated with adverse bone health outcomes, including increased fracture risk, alterations in BMD, hypomagnesemia, and dental implant failure. While these findings highlight potential concerns for long-term PPI users, the current evidence's low certainty underscores the need for robust, high-quality research to clarify these associations.
ABSTRACT
BACKGROUND: The association of homocysteine with coronary artery disease (CAD) has been explored previously with mixed findings. The present Systematic Review and Meta-Analysis (SRMA) has assessed the pooled estimate of association between homocysteine (Hcy) and CAD, and its variation over the period and geography. METHODS: Systematic literature search was done in PubMed, Scopus and Cochrane to identify the observational studies that have reported mean Hcy among cases (CAD) and control. The SRMA was registered in PROSPERO (ID-CRD42023387675). RESULTS: Pooled standardized mean difference (SMD) of Hcy levels between the cases and controls was 0.73 (95% CI 0.55-0.91) from 59 studies. Heterogeneity was high (I2 94%). The highest SMD was found among the Asian studies (0.85 [95% CI 0.60-1.10]), while the European studies reported the lowest SMD between the cases and controls (0.32 [95% CI 0.18-0.46]). Meta-regression revealed that the strength of association was increasing over the years (Beta = 0.0227, p = 0.048). CONCLUSIONS: Higher homocysteine levels might have a significant association with coronary artery diseases, but the certainty of evidence was rated low, owing to the observational nature of the studies, high heterogeneity, and publication bias. Within the population groups, Asian and African populations showed a greater strength of association than their European and American counterparts, and it also increased over the years.
ABSTRACT
PURPOSE: Intraocular pressure (IOP) control is paramount during ophthalmic surgeries to ensure successful outcomes and prevent complications. Intravenous mannitol has been explored for its ability to manage IOP fluctuations in both vitrectomized and non-vitrectomized eyes. This meta-analysis aimed to assess the efficacy of mannitol in controlling IOP across these patient groups. DESIGN: Systematic review and meta-analysis METHODS: A literature search was conducted across PubMed, EMBASE, Scopus and Web of Science from inception up to 01 March 2024, focusing on studies investigating mannitol's impact on IOP in vitrectomized and non-vitrectomized eyes. Randomized controlled trials, cohort studies, and case-control studies were included, while case reports and review articles were excluded. The primary outcome was the change in IOP following mannitol administration. Meta-analysis was performed using a random-effects model. R software (V 4.3) was used for statistical analysis. RESULTS: Our search included five studies of both vitrectomized (145 eyes) and non-vitrectomized eyes (91 eyes). The meta-analysis demonstrated significant IOP reductions following mannitol administration across multiple time points. Three studies were included at 30 minutes and 2 studies at all other time points in the analysis. In vitrectomized eyes, notable decreases were observed: at 30 minutes, the Ratio of Means (ROM) was 0.81 (95% CI: 0.53; 1.24), indicating a 19% reduction; at 60 minutes, the ROM of 0.833 (95% CI: 0.77; 0.89) showed a 16.7% reduction; at 90 minutes, the ROM of 0.757 (95% CI: 0.755; 0.758) corresponded to a 24.3% reduction; at 2 hours, the ROM of 0.726 (95% CI: 0.642; 0.820) reflected a 27.4% reduction; at 3 hours, the ROM of 0.692 (95% CI: 0.600; 0.797) resulted in a 30.8% reduction; and at 4 hours, the ROM of 0.700 (95% CI: 0.363; 1.350) indicated a 30% reduction. No significant changes were observed on IOP with mannitol administration when comparing vitrectomized versus non- vitrectomized eyes. CONCLUSION: Intravenous mannitol effectively reduces IOP in both vitrectomized and non-vitrectomized eyes, demonstrating its utility in the acute management of elevated IOP during and after ophthalmic surgeries. These findings support the integration of mannitol into perioperative care protocols. However, further research, particularly randomized controlled trials and studies with broader demographic representation, is needed to optimize mannitol's usage and fully understand its long-term safety and efficacy.
ABSTRACT
PURPOSE: The optimal management of pediatric traumatic macular holes (TMH) is unclear from lack of prospective randomized trials. The literature is divided into early (≤1month post-trauma), delayed (>1 month) pars plana vitrectomy (PPV), and observation. Our aim is to find which group can achieve best-superior spectacle corrected visual acuity (VA), visual gain, and time for hole closure. DESIGN: Systematic review. METHODS: This systematic review was registered with PROSPERO (ID:CRD42022383134). The databases searched from inception until July 31, 2023, were MEDLINE OVID, Scopus, Web of Science, Embase, and Google Scholar. The articles were screened for title and abstract then for full text. Risk of bias was also assessed. Three outcome measures were analyzed: final VA, visual gain, and time to closure of macular hole (MH). MH size was divided into small (≤250 µm), medium (>250-500 µm), and large (>500 µm). RESULTS: Ninety eight (98) studies with 234 patients in the PPV group and 87 patients in the observation group were included in the review. Final VA (logarithm of the minimum angle of resolution) and visual gain were respectively in PPV vs observation groups: (1) small MH 0.37 ± 0.52 vs 0.42 ± 0.56 (P = .484) and -0.96 ± 0.83 vs -0.49 ± 0.40 (P = .005); (2) medium MH 0.58 ± 0.39 vs 0.34 ± 0.34 (P = .06) and -0.36 ± 0.42 vs -0.74 ± 0.44 (P < .001); (3) large MH 0.62 ± 0.42 vs 0.59 ± 0.35 (P = .337) and -0.31 ± 0.48 vs -0.62 ± 0.37 (P = .11). Small TMH had comparable closure time: 3.21 ± 2.52 months vs 3.49 ± 4.43 (P = .954) in the PPV and observation groups. Early and late PPV yielded comparable final VA 0.67 ± 0.66 vs 0.54 ± 0.35 (P = .576) and visual gain -0.58 ± 0.69 vs -0.49 ± 0.48 (P = .242) in the PPV and observation groups. CONCLUSIONS: PPV was very effective in closing TMH and VA gain in children throughout a wide range of hole size. Early and delayed PPV yielded similar anatomic and visual results. Observation and PPV yielded comparable final VA and closure time. Clinicians can choose either early PPV or delayed PPV when healing biomarkers are absent on periodic optical coherence tomography.
ABSTRACT
INTRODUCTION: Cases of Guillain-Barré Syndrome (GBS) have been believed to be associated with the novel COVID-19 infection, and also with the following vaccines developed against the infection. Our work aims to investigate the incidence of GBS after COVID-19 vaccination, and describe its clinical characteristics and potential confounders. METHODS: An electronic search was conducted through four databases: PubMed, Scopus, medRxiv, and Google Scholar for all case reports and case series describing after COVID-19 vaccine administration. All published articles from inception until November 1st, 2022 were included. Differences between groups were assessed using Pearson chi-square test. Modified Erasmus GBS Outcome Score (mEGOS) for the ability to walk after GBS was calculated for all cases with sufficient clinical data, and Kaplan-Meier survival analysis was performed to study the effect of vaccine type on the relationship between vaccination time and complication of GBS. RESULTS: About 103 studies describing 175 cases of GBS following COVID-19 vaccination were included. The Acute Inflammatory Demyelinating Polyradiculoneuropathy subtype was the most reported subtype with 74 cases (42.29%). The affected age group averaged around 53.59 ±18.83 years, with AMSAN occurring in a rather older group (63.88 ±20.87 years, p=0.049). The AstraZeneca vaccine was associated with AIDP (n=38, 21.71%) more than other vaccines, p=0.02. The bilateral facial palsy subtype was mostly linked to adenoviral vector vaccinations, accounting for an average of 72% of the total BFP cases. Dysesthesias was the most reported sensory complication (60%, p=0.349). Most GBS patients survived (96%, p=0.036), however, most patients had low mEGOS scores (4 ±3.57, p<0.01). On average, patients developed GBS at 13.43 ±11.45 days from vaccination (p=0.73), and survival analysis for complication of GBS into mechanical ventilation or walking impairment yielded a severely increased probability of complication after 25 days (p<0.01). Intravenous immunoglobulins (p=0.03) along with rehabilitation (p=0.19) were the most commonly used treatment. CONCLUSION: This work investigates the incidence of Guillain-Barré Syndrome after COVID-19 vaccination. Most cases occurred after receiving the AstraZeneca or Pfizer vaccines, and despite low mortality rates, ambulation was compromised in most patients. A higher risk of GBS complication is associated with an onset later than 12-13 days, particularly with Pfizer, AstraZeneca, and Moderna vaccines. No specific predisposing or prognostic factor was identified, and the relation between the COVID-19 vaccines and GBS remain unclear.

Congenital dyserythropoietic anemias (CDA) is a heterogeneous class of anemia of varying degrees of ineffective erythropoiesis and secondary hemochromatosis. We reported a case of CDA and showed our approach to reaching a diagnosis, highlighting the importance of the typical morphological appearance of bone marrow erythroblasts to reach the diagnosis.
ABSTRACT
We conducted this research to determine the prevalence rate and presentation patterns with microcystic macular oedema (MMO) in glaucoma patients. The protocol was pre-registered on PROSPERO ( CRD42022316367 ). PubMed, Scopus, Web of Science, EMBASE, ProQuest, EBSCOHost, CENTRAL, clinicaltrials.gov, and Google Scholar were searched for articles reporting MMO in glaucoma patients. The primary outcome was the prevalence of MMO, while secondary outcomes included the comparison between MMO and non-MMO in terms of patients' characteristics (age, gender), glaucoma stage, and ocular parameters (axial length (AL), intraocular pressure, mean deviation, spherical equivalent). Data are reported as mean difference (MD) or log odds ratio (logOR) along with their corresponding 95% confidence intervals (CI) for continuous and dichotomous outcomes, respectively. The quality of included studies was assessed using the NIH tool, and the certainty of evidence was assessed using GRADE framework. Ten studies (2128 eyes) were included, revealing an overall prevalence rate of MMO of 8% (95%CI: 5-12%). When compared to non-MMO group, MMO was associated with lower age (MD = -5.91; 95%CI: -6.02: -5.20), greater risk of advanced glaucoma stage (LogOR=1.41; 95%CI: 0.72: 2.09), and lower mean deviation of the visual field (MD = -5.00; 95%CI: -7.01: -2.99). No significant difference was noted between both groups in terms of gender, axial length, or spherical equivalent. Three studies had good quality while seven had poor quality. MMO is a prevalent observation in glaucoma patients and is associated with patients' age and stage of the disease. However, the certainty of evidence remains very low.

Objectives: The incidence of bladder cancer in the Middle East is increasing. Nevertheless, data on the young population with urothelial carcinoma (UC) of the urinary bladder in this region is scarce. Therefore, we evaluated clinical and tumor characteristics, in addition to treatment details in patients younger than 45 years old. Methodology: We reviewed all patients presenting with UC of the urinary bladder from July 2006 to December 2019. Clinical characteristics including demographics, stage at presentation, and treatment outcomes were extracted. Results: Out of 1272 new cases of bladder cancer, a total of 112 (8.8%) patients were ≤45 years old. Seven patients (6%) had nonurothelial histology and were excluded from the study. The remaining 105 eligible patients with UC had a median age at presentation of 41 years (35-43). Ninety-three patients (88.6%) were males. Tumor stage at presentation: nonmuscle invasive disease (Ta-T1), locally advanced muscle-invasive bladder cancer (MIBC) (T2-3), and metastatic disease were 84.7%, 2.8%, and 12.5%, respectively. All patients with MIBC received neoadjuvant cisplatin-based chemotherapy. Radical cystectomy was performed in 8 (7.6%) cases; three patients with MIBC and five with high-volume non-MIBC. Neobladder reconstruction was done in six patients. A total of 13 patients with metastatic disease (93%) received palliative chemotherapy (gemcitabine/cisplatin), and one (7%) was a candidate for best supportive care only. Conclusion: Bladder cancer is relatively rare in the young population, although the incidence at our region is higher than other reports in the literature. Most patients present with early disease. Early diagnosis and multidisciplinary approach are paramount for the management of these patients.
ABSTRACT
BACKGROUND: SARS-CoV-19 infection is associated with an increased risk of thrombotic events. We present a case of acute middle cerebral artery ischemic stroke in a patient with SARS-CoV-19 infection despite being on warfarin with supratherapeutic INR (International Normalized Ratio). CASE PRESENTATION: A 68-year-old Caucasian female with multiple comorbidities was admitted to the hospital with symptoms of upper respiratory tract infection. A rapid antigen test confirmed the diagnosis of COVID-19 pneumonia, and intravenous remdesivir was initiated. On the fifth day of admission, the patient experienced sudden onset confusion, slurred speech, left-sided hemiplegia, right-sided eye deviation, and left-sided facial droop. Imaging studies revealed an occlusion of the distal anterior M2 segment of the right middle cerebral artery, and an MRI of the brain confirmed an acute right MCA infarction. Notably, the patient was receiving warfarin therapy with a supratherapeutic INR of 3.2. CONCLUSIONS: This case report highlights the potential for thromboembolic events, including stroke, in patients with COVID-19 infection, even when receiving therapeutic anticoagulation therapy.

Balanced nutrition is crucial for a healthy eye and vision. Many nutritional deficiencies can result in vision impairment. This article reviews the ocular manifestations of vitamin deficiencies, including vitamin A, vitamin B1 and B12, vitamin C, vitamin D, and vitamin E, and minerals such as zinc. It discusses different ophthalmic symptoms and signs, including dry eye disease, corneal xerosis, decreased night vision, subconjunctival hemorrhage, and retinal changes similar to retinitis pigmentosa. We strongly recommend using multi-vitamin supplements for treating many diseases such as age-related macular degeneration.
