Clinical and dermographics profile of glaucoma patients in Hebron - Palestin...Riyad Banayot
ABSTRACT
BACKGROUND: The purpose of the study was to describe the clinical profile of glaucoma types, treatment modalities, visual outcomes, and intraocular pressure (IOP) control for patients in Palestine.MATERIAL AND METHODS: Data collection was done through the hospital record review, which included basic demographics including file number, age, sex, family history of glaucoma, history of anti-glaucoma and steroid medication, history of ocular trauma or surgery, etiology of secondary glaucoma and history of systemic illness. All the patients had a comprehensive eye examination, including visual acuity, intraocular pressure, vertical cup-disc ratio, and gonioscopy. Data were obtained, tabulated, and organized using Microsoft Excel, and statistical analyses were done using Wizard Version 1.9.49 by Evan Miller.RESULTS: There were 100 females with a mean age of 53 and 101 males with a mean age of 67. Primary open-angle glaucoma and its variants represented 45.3% of all patients, while secondary glaucoma represented 40.3% and primary angle closure glaucoma represented 10.4%. The prevalence of glaucoma increased with age, and the last visual acuity (VA) showed that 39.2% of eyes had Normal/near normal VA. The highest average IOP of 25 mm Hg was recorded among secondary glaucoma patients. Of all glaucoma eyes studied, 64% were on one or two medications, and the most common surgical procedures performed were peripheral iridectomy 18.2% followed by trabeculectomy 15.5%. CONCLUSION: Primary open-angle glaucoma (POAG) was the predominant glaucoma. Glaucoma increased significantly with advancing age. Pseudoexfoliation and neovascular glaucoma comprised the majority of secondary glaucoma.
Acute ocular chemical injury: a descriptive assessment and management review ...Riyad Banayot
Background: The purpose of the study was to assess caregivers’ compliance with the management protocol for
chemical injury at St. John Eye Hospital, Jerusalem.
Materia l and methods: Charts of all new chemical injury patients who presented to St. John Eye Hospital,
Jerusalem, between January and December 2019 were retrospectively reviewed. Data categories collected included:
Presentation, age, sex, injury, irrigation, lids, visual acuity, slit-lamp examination (SLE), management plan, and
medications given. Data were stored and analysed using Excel.
Results: Patients’ presentation date and time, sex, and age were recorded in over 90% of cases. The mechanism of
injury and type of offending chemical were recorded in 65% of cases. The irrigating solution was identified in 50%
of cases. Corrected visual acuity was recorded in both eyes in almost 50% of cases. Limbal ischemia was documented
in 45% of cases, and intraocular pressure (IOP) was recorded in 25%. The management plan and explanation of the
condition to patients were documented in less than 50% of cases. Antibiotics and steroids (drops/ointment) were
prescribed in 92.5% of cases.
Conclusi ons: The results of this study reveal that our documentation needs improvement for several parameters.
Several recommendations were formulated:
1. Emphasize to caregivers that irrigation must be done first.
2. Corrected visual acuity should be attempted for both eyes in all cases, and reasons for not recording it should be
documented.
3. It is important to document and record limbus details, iris details, and IOP in all cases.
open-globe injuries in palestinePalestine: epidemiology and factors associate...Riyad Banayot
Background: The purpose was to describe the epidemiology of open-globe injury (OGI) in Palestine and identify
the prognostic factors associated with profound visual loss.
Materia l and methods: The current study is a retrospective review of hospital files for 83 consecutive patients
with OGI who presented to St. John Eye Hospital, Jerusalem, within 5 years, between 2009 and 2013. Demographic
details included age, gender, wound characteristics, and visual acuity (VA). The Ocular Trauma Classification Group
was used for wound location, classification, and scoring for each case.
Results: We identified 83 OGI that presented to St. John eye hospital. The study group included 62 males and
21 females. The mean age was 16.66 years ± 3.216. The most frequent injuries were playground injuries (59%),
followed by workplace injuries (26.5%). Penetrating injuries represented 45.8% of injuries, and rupture globes
occurred in 39.8% of cases. The most frequent objects causing injury were metal (31.3%) and stone (20.5%). Kinetic
impact projectiles were a statistically significant poor prognostic factor for the visual outcome. Variables that
were statistically significant poor prognostic factors for visual outcome included: retinal detachment, macular scar,
vitreous hemorrhage.
Conclusi on: This study showed that the act of demonstration, street injuries, kinetic impact projectiles, zone III
injuries, globe disruption, retinal detachment, vitreous hemorrhage, and a poor VA at the first visit are poor prognostic
factors for OGI. Recognition of these prognostic factors will help the ophthalmologist evaluate the injury
and its prognosis.
Use of digital retinal camera to detect prevalence and severity of diabetic ...Riyad Banayot
ABStrAct
BAckGround: The purpose of this study was to determine the prevalence of diabetic retinopathy among Palestinian
refugees serviced by the Diabetic Retinopathy Screening Program in the Occupied Palestinian Territories (DRS-
-OPT).
MAterIAl And MethodS: This is a retrospective study of retinal images of 1891 diabetic patients in 15 urban
UNRWA clinics participating in the DRS-OPT program in Palestine over 12 months. A nonmydriatic Canon CR-2
fundus retinal camera was used to capture two 450 non-stereo fundus images for each eye. Qualified graders (nurses)
performed the grading based on the DRS-OPT grading system.
reSultS: Out of the 1891 diabetic patients screened, 1694 had at least one gradable eye. 16% of patients had
diabetic retinopathy (5.7% had mild nonproliferative diabetic retinopathy, 4.3% had moderate nonproliferative
diabetic retinopathy, 1.1% had severe, moderate nonproliferative diabetic retinopathy, and 1.7% had proliferative
diabetic retinopathy. Maculopathy without retinopathy amounted to 3%. Other findings included the identification
of blinding diseases such as age-related macular degeneration and optic disc glaucomatous cupping.
concluSIonS: The retinopathy screening program using a nonmydriatic fundus camera identified diabetic retino-
pathy in 16% of diabetic Palestinian refugees. A total of 72% of these patients were diabetics with nonproliferative
retinopathy. This program can be used to prevent progression by facilitating the education of patients and early
intervention.
Bilateral lens capsule rupture in a patient with previously undiagnosed alpor...Riyad Banayot
Ophthalmologists may be the first to consider the diagnosis of Alport’s Syndrome based on lens changes. Uncontrolled Blood pressure can delay surgery during which time IOP should be monitored closely. Results of lensectomies with foldable IOL implantation are successful. To our knowledge, this is the second report of a case of bilateral lens capsule rupture in a patient with previously undiagnosed Alport’s Syndrome.
Evaluating the optic nerve head in glaucomaRiyad Banayot
The best method readily available to the clinician for performing this examination is high plus lens fundus biomicroscopy. Optimal magnification can be achieved by using a +60D lens which provides 1.5 times the magnification of a 90D lens. During this examination the patient's pupils must be maximally dilated with a combination of mydriatic agents such as 1% Tropicamide and 2.5% Phenylephrine.

Medical Technology Tackles New Health Care Demand - Research Report - March 2...pchutichetpong
M Capital Group (“MCG”) predicts that with, against, despite, and even without the global pandemic, the medical technology (MedTech) industry shows signs of continuous healthy growth, driven by smaller, faster, and cheaper devices, growing demand for home-based applications, technological innovation, strategic acquisitions, investments, and SPAC listings. MCG predicts that this should reflects itself in annual growth of over 6%, well beyond 2028.
According to Chris Mouchabhani, Managing Partner at M Capital Group, “Despite all economic scenarios that one may consider, beyond overall economic shocks, medical technology should remain one of the most promising and robust sectors over the short to medium term and well beyond 2028.”
There is a movement towards home-based care for the elderly, next generation scanning and MRI devices, wearable technology, artificial intelligence incorporation, and online connectivity. Experts also see a focus on predictive, preventive, personalized, participatory, and precision medicine, with rising levels of integration of home care and technological innovation.
The average cost of treatment has been rising across the board, creating additional financial burdens to governments, healthcare providers and insurance companies. According to MCG, cost-per-inpatient-stay in the United States alone rose on average annually by over 13% between 2014 to 2021, leading MedTech to focus research efforts on optimized medical equipment at lower price points, whilst emphasizing portability and ease of use. Namely, 46% of the 1,008 medical technology companies in the 2021 MedTech Innovator (“MTI”) database are focusing on prevention, wellness, detection, or diagnosis, signaling a clear push for preventive care to also tackle costs.
In addition, there has also been a lasting impact on consumer and medical demand for home care, supported by the pandemic. Lockdowns, closure of care facilities, and healthcare systems subjected to capacity pressure, accelerated demand away from traditional inpatient care. Now, outpatient care solutions are driving industry production, with nearly 70% of recent diagnostics start-up companies producing products in areas such as ambulatory clinics, at-home care, and self-administered diagnostics.

Antibiotic Stewardship by Anushri Srivastava.pptxAnushriSrivastav
Stewardship is the act of taking good care of something.
Antimicrobial stewardship is a coordinated program that promotes the appropriate use of antimicrobials (including antibiotics), improves patient outcomes, reduces microbial resistance, and decreases the spread of infections caused by multidrug-resistant organisms.
WHO launched the Global Antimicrobial Resistance and Use Surveillance System (GLASS) in 2015 to fill knowledge gaps and inform strategies at all levels.
ACCORDING TO apic.org,
Antimicrobial stewardship is a coordinated program that promotes the appropriate use of antimicrobials (including antibiotics), improves patient outcomes, reduces microbial resistance, and decreases the spread of infections caused by multidrug-resistant organisms.
ACCORDING TO pewtrusts.org,
Antibiotic stewardship refers to efforts in doctors’ offices, hospitals, long term care facilities, and other health care settings to ensure that antibiotics are used only when necessary and appropriate
According to WHO,
Antimicrobial stewardship is a systematic approach to educate and support health care professionals to follow evidence-based guidelines for prescribing and administering antimicrobials
In 1996, John McGowan and Dale Gerding first applied the term antimicrobial stewardship, where they suggested a causal association between antimicrobial agent use and resistance. They also focused on the urgency of large-scale controlled trials of antimicrobial-use regulation employing sophisticated epidemiologic methods, molecular typing, and precise resistance mechanism analysis.
Antimicrobial Stewardship(AMS) refers to the optimal selection, dosing, and duration of antimicrobial treatment resulting in the best clinical outcome with minimal side effects to the patients and minimal impact on subsequent resistance.
According to the 2019 report, in the US, more than 2.8 million antibiotic-resistant infections occur each year, and more than 35000 people die. In addition to this, it also mentioned that 223,900 cases of Clostridoides difficile occurred in 2017, of which 12800 people died. The report did not include viruses or parasites
