ABSTRACT

INTRODUCTION: Osteoarthritis is a chronic, degenerative, and debilitating disease associated with significant long-term morbidity and disability. The pathogenesis of osteoarthritis is not completely understood but involves an interplay between environmental risk factors, joint mechanics, abnormal pain pathways and upregulation of inflammatory signaling pathways. Current therapeutic options for patients are limited to conservative management, minimal pharmacological options or surgical management, with significant caveats to all approaches. AREAS COVERED: In this review we have set out to investigate current phase II/III clinical trials by undertaking a pubmed search. Examined clinical trials have explored a myriad of potential therapeutics from conventional disease-modifying anti-rheumatic drugs and biologics usually used in the treatment of inflammatory arthritides, to more novel approaches targeting inflammatory pathways implicated in osteoarthritis, cartilage degeneration or pain pathways. EXPERT OPINION: Unfortunately, most completed phase II/III clinical trials have shown little impact on patient pain scores, with the exception of the traditional DMARD methotrexate and Sprifermin. Methotrexate has been shown to be beneficial when used in the correct patient cohort (MRI proven synovitis). Sprifermin has the longest follow-up data of 5 years and has been shown to reduce loss of MRI-measured cartilage thickness and pain scores.

ABSTRACT

Objectives: This study aimed to assess healthcare professionals' awareness and acceptance of telemedicine residing in Pakistan. Materials and Methods: A cross-sectional study was conducted across Pakistan from November 2021 to March 2022. Data entry was done through a self-administered questionnaire. In this survey, the non-probability purposive sampling method was adopted. Medical doctors from all specialties that fall into the age category of 20-60 years were included in this study. Statistical Package for Social Sciences (SPSS) version 22.0 was used for univariate data analysis. Results: Among the 860 healthcare professionals who received the survey, 198 responded (23.0% response rate). The mean ± SD age of the participants was 31.16 ± 8.56. The results were found to be statistically significant for knowledge about telemedicine among healthcare professionals workplace, that is, healthcare professionals working in the private sector indicated a high level of awareness regarding telemedicine as compared to those in the public sector (p = 0.03). A significant difference (p-value ⩽ 0.05) in knowledge was seen among doctors working in the public sector and those working in a private setup. Results indicate significant positive associations between telemedicine utilization and perceived benefits over disadvantages (ß = 1.03, p = 0.017), reliance among healthcare professionals (ß = 1.22, p = 0.008), and enhancement in healthcare quality (ß = 1.42, p = 0.001). Moreover, familiarity with telemedicine correlates strongly with its usage (ß = 2.56, p < 0.000). Conclusion: Overall, healthcare professionals exhibited satisfactory knowledge regarding telemedicine and showed an accepting attitude toward telemedicine. Our study recommends enhancing the importance of Telemedicine training at the Healthcare professionals' level to produce quality service delivery in healthcare organizations.


Facilitators and barriers in acceptance of telemedicine among healthcare providers in Pakistan: A Cross-sectional survey: The aim of this study, was to evaluate healthcare professionals' knowledge and acceptance of telemedicine in Karachi, Pakistan. A cross-sectional survey was carried out between November 2021 and March 2022, and 198 out of 860 healthcare professionals responded (representing a 23.0% response rate). The participants' average age was 31.16 years. The results showed that healthcare professionals in the public and private sectors differed significantly in their awareness of telemedicine, with the former group having higher awareness levels. Most of the medical professionals showed adequate understanding and acceptance of telemedicine. However, in order to improve service delivery in healthcare organizations, the study emphasizes the necessity for improved telemedicine awareness and training among healthcare providers, especially in the public sector. The findings highlighted how crucial it is to integrate telemedicine within medical education.

ABSTRACT

INTRODUCTION: Significant progress has been made in the diagnosis and management of axial spondyloarthritis (AxSpA) over recent decades. A greater understanding of the immunopathogenesis of the disease has paved the way for the development of targeted treatments. Their efficacy has been demonstrated in randomized controlled trials, meta-analyses and one head-to-head study of biologic DMARDs. Treatment decisions in AxSpA are currently influenced by patient choice, co-morbidity, clinician familiarity and cost. AREAS COVERED: We review the clinical trials that underpin the evidence base for treatments in AxSpA. We also cover the meta-analyses and head-to-head data that seek to support clinicians in personalizing treatment decisions. Further, we discuss the recent international guidelines that provide clinicians with treatment pathways and guidance. EXPERT OPINION: We conclude that treatment decisions in managing both radiographic and non-radiographic AxSpA should be based on shared decision-making with patients, the clinical effectiveness of drug class, co-morbidity and cost. At present, we have limited head-to-head data to prioritize one drug class over another for first-line treatment but can recommend tumor necrosis factor (TNF), interleukin 17 (IL17) and JAK inhibition as being comparable in terms of clinical, structural and patient-reported outcome measures. Further real-world data may guide treatment decision-making in individual patients.

ABSTRACT

Triboelectric nanogenerators (TENGs) are devices that efficiently transform mechanical energy into electrical energy by utilizing the triboelectric effect and electrostatic induction. Embroidery triboelectric nanogenerators (ETENGs) offer a distinct prospect to incorporate energy harvesting capabilities into textile-based products. This research work introduces an embroidered triboelectric nanogenerator that is made using polyester and nylon 66 yarn. The ETENG is developed by using different embroidery parameters and its characteristics are obtained using a specialized tapping and friction device. Nine ETENGs were made, each with different stitch lengths and line spacings for the polyester yarn. Friction and tapping tests were performed to assess the electrical outputs, which included measurements of short circuit current, open circuit voltage, and capacitor charging. One sample wearable embroidered energy harvester collected 307.5 µJ (24.8 V) of energy under a 1.5 Hz sliding motion over 300 s and 72 µJ (12 V) of energy through human walking over 120 s. Another ETENG sample generated 4.5 µJ (3 V) into a 1 µF capacitor using a tapping device with a 2 Hz frequency and a 50 mm separation distance over a duration of 520 s. Measurement of the current was also performed at different pressures to check the effect of pressure and validate the different options of the triboelectric/electrostatic characterization device. In summary, this research explains the influence of embroidery parameters on the performance of ETENG (Embroidery Triboelectric Nanogenerator) and provides valuable information for energy harvesting applications.

ABSTRACT

INTRODUCTION: IL-17 has been described as a pro-inflammatory cytokine that is relevant in the seronegative spondylarthritides with IL-17 targeted therapies being licensed for their treatment.There is evidence to demonstrate that IL-17 is found in RA joints and contributes to the pro-inflammatory cascade. This results in synovial hyperplasia and osteoclastogenesis thus causing joint destruction and bony erosions. AREAS COVERED: This review article summarizes trials that have studied the use of IL-17 targeted therapies in RA patients who have failed conventional synthetic disease-modifying therapy (C-DMARDS) and biologic DMARDS. EXPERT OPINION: The trials that have studied IL-17 inhibitors in RA patients have only shown a modest improvement in disease activity. In several trials, the primary endpoint was not achieved whilst in others, when comparing with existing licensed biologics for RA, did not demonstrate any superiority.Tissue Necrosis Factor-alpha (TNF-α) likely plays more of a pivotal role in the pathogenesis of RA with IL-17 having a synergistic effect. Therefore, in our opinion, IL-17 inhibitors as an independent therapy for RA are less likely to provide a cost-effective benefit. There may be scope to potentially combine it with TNF-α-inhibitors (TNF-i), but this requires further research especially with the potential concerns related to increased immunosuppression.

ABSTRACT

Background Diagnostic delay of axial spondyloarthritis (axSpA) is a widely recognized issue worldwide, providing a great burden for patients with this disease. AxSpA is present in a significant proportion of patients with inflammatory bowel disease (IBD). This UK study primarily aims to identify the presence of inflammatory back pain (IBP) in patients attending IBD clinic. Further aims of this study include investigating if participants had received further referrals and diagnoses for their IBP and considering factors contributing to diagnostic delay. Methods Patients were recruited from a Royal Free London NHS Trust hospital's IBD clinic. Each participant completed a 23-question survey. The Berlin criteria were applied to the questions to investigate the presence of IBP. Further questions were asked about their IBD diagnosis and treatment, the healthcare professionals they had seen for their back pain, and other extra-articular features associated with axSpA. Results Seventy-five patients completed the online survey sent out via email. Forty percent (n = 30) of participants were female and 60% (n = 45) were male. Sixty-one percent (n = 36) of participants from the colitis clinic reported they had back pain, and 41% of the participants reported back pain for over three months. Of these, 39% (12) of participants fulfilled the Berlin criteria for IBP. Of patients experiencing back pain for over three months, we found that 10% (3) fulfilled the Berlin criteria but had not received a diagnosis for their IBP. All patients who had fulfilled the Berlin criteria but had not received a diagnosis for their IBP had seen their general practitioner (GP) and an allied healthcare professional, but not a rheumatologist. Conclusions This study highlights the presence of possibly undiagnosed axSpA in patients with IBD. The reasons for the diagnostic delay of axSpA are multifactorial. We consider specific patient characteristics, lack of awareness and education of the condition, and issues in the referral process. There is a need to improve education and awareness of axSpA, reconsider referral processes, and consider new initiatives such as joint specialty clinics to identify and treat axSpA on time.

ABSTRACT

Background In the United Kingdom, diagnostic delay remains a challenge in axial spondyloarthritis (axSpA). Psoriasis is a frequently identified extra-musculoskeletal manifestation associated with axSpA. In this study, we aimed to determine the prevalence of inflammatory back pain (IBP) in psoriasis patients at a specialized psoriasis dermatology clinic in a London NHS Trust. Our primary goal was to identify psoriasis patients with IBP who were not referred to a rheumatologist, potentially leading to axSpA diagnostic delays. Additionally, we aimed to investigate factors contributing to these delays and strategies to address them. Methodology A patient survey consisting of 22 questions was used to assess the prevalence of IBP among 66 psoriasis patients attending a weekly specialized psoriasis dermatology clinic within a London NHS Trust between May and July 2023. The survey comprised patient demographic information along with inquiries about the existence of back pain exceeding three months. The Berlin Criteria was utilized to identify IBP among patients who reported experiencing back pain for over three months. Additionally, the survey sought information on prior diagnosis of axSpA and whether participants had consulted healthcare professionals regarding their back pain. Results Of the 66 patients invited, 51 (77%) completed the survey. The average age of the patients was 50 years (range = 19-74 years), with 58.8% being female. The mean duration of psoriasis was 15.7 years (range = 2-44 years). Overall, 45% (23/51) reported back pain lasting over three months. Among the patients who reported back pain for more than three months, 13 met the Berlin Criteria for IBP (25% of the total surveyed), and only four of these patients had a diagnosis of axSpA. Notably, seven patients (14% of the total surveyed) potentially had undiagnosed axSpA. General practitioners (GPs) were commonly consulted for back pain, yet only 39% of those with prolonged back pain had seen a rheumatologist. Despite experiencing prolonged back pain, 17% of patients had not sought healthcare advice for their symptoms. Conclusions This study highlights that IBP is a common yet underdiagnosed comorbidity in psoriasis patients. Dermatologists, GPs, and other allied healthcare professionals play a crucial role in detecting early axSpA. However, limited awareness of IBP hinders its identification in psoriasis patients and subsequent referral to rheumatologists. This highlights the need for improving awareness and education regarding axSpA among dermatologists and allied healthcare professionals as well as the public and patients to ensure timely diagnosis. The development of simple and easy-to-administer screening questionnaires to aid non-rheumatologists in identifying patients with IBP together with simplified referral pathways would increase onward referrals of appropriate patients to rheumatologists.

ABSTRACT

Background: Routine vaccination has remained historically low in major urban pockets of Pakistan, and now lags behind rural vaccination rates. Grossly insufficient publicly funded primary healthcare infrastructure, heterogeneous mix of providers and multi-ethnicity of populations pose challenges in the delivery of essential health services. This paper ascertains factors associated with uptake of routine childhood vaccination, using Pentavalent-3 vaccine, as a proxy indicator for completion of age-appropriate vaccines in urban slums of Karachi, at high risk of Polio and vaccine preventable disease outbreaks. Methods: Data was drawn from baseline assessment of an urban immunization delivery pilot project in urban slums of Karachi, Pakistan. The study sample comprised of 2,097 households with children aged 4-12 months, sampled through a cross-sectional cluster survey, applying a structured questionnaire. Multivariable logistic regression was used to determine the association between Penta-3 vaccination, as the outcome variable, and predictor variables including socio-demographic characteristics and healthcare access factors. Results: The findings showed that the likelihood of being immunized with Penta-3 was higher for non-Pashtun ethnicity [adjusted odds ratio (aOR) 1.69; 95% CI 1.33-2.14], children of educated mothers, secondary or higher [aOR 2.95, 95% CI 2.34-3.71], and those whose fathers were formally employed (aOR 1.53; 95% CI 1.19-1.97). No association was seen by gender of child [aOR 0.89; 95% CI 0.73-1.08], and place of new born delivery [aOR 1.01; 95% CI 0.83-1.24]. Conclusion: Pockets of critically low under-vaccinations within the urban slums of Karachi are associated with Pashtun ethnicity, distance to the vaccination centre, lack of mothers' education and lack of stable family income as in the case of unemployed and daily wage-earning fathers. Recognition of these factors is required in designing contextually appropriate strategies to address vaccine inequity in urban settings.

ABSTRACT

INTRODUCTION: GCA (giant cell arteritis) and PMR (polymyalgia rheumatica) are two overlapping inflammatory rheumatic conditions that are seen exclusively in older adults, sharing some common features. GCA is a clinical syndrome characterized by inflammation of the medium and large arteries, with both cranial and extracranial symptoms. PMR is a clinical syndrome characterized by stiffness in the neck, shoulder, and pelvic girdle muscles. Both are associated with constitutional symptoms. AREAS COVERED: In this review, we assess the established and upcoming treatments for GCA and PMR. We review the current treatment landscape, completed trials, and upcoming trials in these conditions, to identify new and promising therapies. EXPERT OPINION: Early use of glucocorticoids (GC) remains integral to the immediate management of PMR and GCA but being aware of patient co-morbidities that may influence treatment toxicity is paramount. As such GC sparing agents are required in the treatment of PMR. Currently there are limited treatment options available for PMR and GCA, and significant unmet needs remain. Newer mechanisms of action, and hence therapeutic options being studied include CD4 T cell co-stimulation blockade, IL-17 inhibition, IL-12/23 inhibition, GM-CSF inhibition, IL-1ß inhibition, TNF-α antagonist and Jak inhibition, among others, which will be discussed in this review.

ABSTRACT

BACKGROUND: Enthesitis is a key feature of spondyloarthropathy (SpA). In recent years, JAK inhibitors have emerged as efficacious drugs in the landscape of advanced therapies for patients with SpA. METHOD: The aim of this scoping literature review was to search the published literature for studies on JAK inhibitors and their effects on enthesitis in patients with SpA and evaluate the data and summarise the findings. The clinical trials reviewed used the Leeds Enthesitis Index, Spondyloarthritis Research Consortium of Canada Enthesitis Index, and Maastrich Ankylosing Spondylitis Enthesitis Score as outcome measures. RESULTS: Tofacitinib, upadacitinib, and filgotinib had numerically greater reductions in the enthesitis scores when compared with placebo. CONCLUSION: While the JAK inhibitors are therapeutic options for enthesitis in SpA, head-to-head studies are needed to compare the JAK inhibitors against the biological drugs (targeting TNF, IL-17, and IL-12/23) as well as studies showing the effects of JAK inhibitors on enthesitis imaging.

ABSTRACT

Background  In the UK, diagnostic delays remain a challenge in axial spondyloarthritis (axSpA). Studies have shown that acute anterior uveitis is the most common extra-articular manifestation associated with axSpA. As part of a National Axial Spondyloarthritis Society (NASS) Aspiring to Excellence quality improvement project, this study aimed to ascertain the burden of inflammatory back pain (IBP) in patients attending a uveitis clinic and to establish the number of these patients who had not been referred to a rheumatologist, thereby contributing to the diagnostic delay. The secondary aims were to explore the factors contributing to the diagnostic delay. Methods  A 22-question patient survey was created to identify the burden of back pain in patients attending a specialist uveitis clinic at a London NHS Trust. Participants were recruited when attending their clinic appointments. Survey content included patient demographics and whether they had experienced back pain for longer than three months. The Berlin Criteria was used to identify the presence of inflammatory back pain, and it was also ascertained whether participants had a previous diagnosis of axSpA. Participants were asked if they had seen any healthcare professionals regarding their back pain and the total number of consultations they had had with each profession. Results  A cohort of 50 patients who attended the uveitis clinic at the Royal Free London NHS Trust completed the survey between February and July 2022. The mean age of the respondents was 52 years with a mean length of time with uveitis of 6.57 years. Of them, 64% were female and 36% were male. Forty per cent (40%) of participants (20 respondents) reported experiencing back pain for more than three months and 12% (six respondents) had a diagnosis of axSpA. Of those who reported back pain for more than three months, the mean age of onset of back pain was 28.6 years. Of the 14 participants (28%) who had back pain and were not diagnosed with axSpA, nine (18%) fulfilled the Berlin criteria for IBP. All participants had seen a GP or allied health professional specifically for their back pain. On average, respondents had seen two allied healthcare professionals, but only 40% (eight) of respondents with back pain had been seen by a rheumatologist. Conclusions  In this study, the data highlights that inflammatory back pain is common in patients with uveitis and the majority of patients with inflammatory back pain had not been referred to a rheumatology service and potentially have undiagnosed axSpA. Contributing factors to this potential delay in diagnosis include a lack of awareness of axSpA and its presenting features and associated conditions and a lack of onward referral for a specialist rheumatology opinion. This highlights the need for public, patient and healthcare professional education and the development of timely referral pathways to reduce delays in diagnosis.

ABSTRACT

BACKGROUND: Cotton dust is generated during various textile manufacturing processes. Only a few studies from Pakistan assessed cotton dust exposure and explored the relationship of duration of work in the textile industry with respiratory health outcomes. We aimed to assess cotton dust exposure and its association with lung function and respiratory symptoms among textile workers in Pakistan. METHODS: We report findings from the baseline survey of the larger study, MultiTex, among 498 adult male textile workers from six mills conducted between October 2015-March 2016 in Karachi, Pakistan. Data collection included the use of standardized questionnaires; spirometry, and area dust measurements through UCB-PATS. Multivariable logistic and linear regression models were developed to assess the association of risk factors with respiratory symptoms and illnesses. RESULTS: We found the mean age of workers to be 32.5 (±10) years; around 25% were illiterate. The prevalence of COPD, asthma, and byssinosis was 10%, 17%, and 2%, respectively. The median cotton dust exposure was 0.33 mg/m3 (IQR: 0.12-0.76). Increased duration of work among non-smokers was associated with a decline in lung function, FVC (-245 ml; 95% CI: -385.71, -104.89) and FEV1 (-200 ml; 95% CI: -328.71, -841.1). Workers with certain job titles (machine operators, helpers, and jobbers), those with greater duration of work, and higher dust exposure, were more likely to report respiratory symptoms and illnesses. CONCLUSIONS: We report a high prevalence of asthma and COPD and a low prevalence of byssinosis. Cotton dust exposure and duration of employment were associated with respiratory health outcomes. Our findings highlight the need for preventive interventions in the textile industry in Pakistan.

ABSTRACT

INTRODUCTION: Over the last two decades, rituximab has become an increasingly popular drug in the treatment of a wide range of rheumatic diseases. However, with the advent of the COVID-19 pandemic, clinicians face challenges in weighing risk against benefit in its use. AREAS COVERED: A review of existing data was performed to examine the relationship between rituximab use, morbidity and mortality from COVID-19, and vaccine efficacy in patients with rheumatic diseases, aiming to guide clinicians in continued use of the medication and consider the direction of future research. A literature review was performed through a search of the PubMed database, using the terms ((SARS-CoV-2) OR (COVID-19)) AND (rituximab) AND (rheumatic), which generated an initial 55 results, with relevant articles then selected for inclusion. EXPERT OPINION: In order to safeguard patients with an ongoing need for rituximab therapy, vaccination remains the primary concern. A target of performing booster doses 6 months after last rituximab dose is a reasonable estimate, which may be made more precise by use of B cell counts, although primary immunization should not be delayed. In those patients who remain seronegative, the use of newer antivirals and broadly neutralizing antibody infusions may help provide further safeguards.

ABSTRACT

This research aims to validate an electrostatics characterization device to better understand the process of static charge generation in textile materials and to see how different factors affect it. This electrostatic device offers a variety of settings for controlling sample electrostatic activation and has a sample size range of up to one square meter. It can move in both horizontal and vertical directions in a controlled manner, providing a variety of possibilities for testing the effect of various movement features on electrostatic charge formation. Not only the textile polymer but also the motion characterizations influence the generation of electrostatic charges in textiles. The influence of frequency, pressure, dwell time between moves, test duration, effect of different sample sizes, and amplitude of movement on electrostatic charge generation was studied in greater detail. Two different parameters of the electrostatic waveform (peak voltage and peak-to-peak voltage) were investigated. The generation of electrostatic charges is proportional to the peak voltage and peak-to-peak voltage of the electrostatic waveform. Overall electrostatic charge generation increases with increasing frequency, stepping height, applied pressure at the same frequency, and sample size, but decreases with increasing dwell time between moves at the same frequency. The charge also increases with test duration until a saturation point is reached.

ABSTRACT

Background Brachial plexus injuries are frequently encountered in the domain of plastic surgery, mostly secondary to road traffic accidents, gunshot injuries, or falls from a height. Many modalities have been described in the management, depending on the level and duration of the injury. C5, C6 and C5, C6, C7 are two common patterns in which nerve repair and transfers are described. At our center, we practice spinal accessory to suprascapular nerve transfer in all patients with upper trunk brachial plexus injury. There are two described approaches for the spinal accessory nerve to suprascapular nerve transfer, i.e. anterior or dorsal. The rationale for doing the posterior approach is that this approach avoids damaging the suprascapular nerve at its entrance in the suprascapular notch under the suprascapular ligament during exploration due to traction. Materials and methods This is a retrospective study with a consecutive sampling of 23 patients presenting at Liaquat National Hospital, Karachi, with upper trunk brachial plexus injuries during the time period from January 2016 to December 2017, i.e. two years. We divided these 23 patients into two groups, one with the anterior approach and the other with a dorsal approach for spinal accessory to suprascapular nerve transfer for shoulder abduction. The mean duration of post-surgical follow-up was from 18 to 24 months and recovery and functional outcomes were assessed. Results Out of the 23 patients that were included, 10 patients were operated on with an anterior approach and 13 with a posterior approach. Fifty percent (50%) of patients operated with the anterior approach and 84% of patients with the posterior showed the best motor grade recovery of M4, respectively, with better performance in patients with the posterior approach as compared to the anterior approach. Conclusion We advocate taking a posterior approach for spinal accessory to suprascapular nerve transfer for shoulder abduction, as it has shown better results with reliable outcomes concerning shoulder abduction, angle of abduction, and range of motion.

ABSTRACT

Between September 2020 and March 2021, Mercy Corps piloted hybrid digital (CAPI) and paper-based (PAPI) data collection as part of its tuberculosis (TB) active case finding strategy. Data were collected using CAPI and PAPI at 140 TB chest camps in low Internet access areas of Punjab and Khyber Pakhtunkhwa provinces in Pakistan. PAPI data collection was performed primarily during the camp and entered using a tailor-performed CAPI tool after camps. To assess the feasibility of this hybrid approach, quality of digital records were measured against the paper "gold standard", and user acceptance was evaluated through focus group discussions. Completeness of digital data varied by indicator, van screening team, and month of implementation: chest camp attendees and pulmonary TB cases showed the highest CAPI/PAPI completeness ratios (1.01 and 0.96 respectively), and among them, all forms of TB diagnosis and treatment initiation were lowest (0.63 and 0.64 respectively). Vans entering CAPI data with high levels of completeness generally did so for all indicators, and significant differences in mean indicator completeness rates between PAPI and CAPI were observed between vans. User feedback suggested that although the CAPI tool required practice to gain proficiency, the technology was appreciated and will be better perceived once double entry in CAPI and PAPI can transition to CAPI only. CAPI data collection enables data to be entered in a more timely fashion in low-Internet-access settings, which will enable more rapid, evidence-based program steering. The current system in which double data entry is conducted to ensure data quality is an added burden for staff with many activities. Transitioning to a fully digital data collection system for TB case finding in low-Internet-access settings requires substantial investments in M&E support, shifts in data reporting accountability, and technology to link records of patients who pass through separate data collection stages during chest camp events.

ABSTRACT

Background Congenital ptosis not only results in an asymmetric facial appearance but can lead to permanent visual disturbances if not addressed at an appropriate time. Crawford used fascia lata for suspension of the eyelid to frontalis muscle, which remains a standard procedure for congenital ptosis correction to date, with an acceptable recurrence rate due to graft slippage. There are many modifications in this technique to reduce this complication; hence, in this study, we share our experience of a modification to improve the outcomes. Methodology This retrospective study was conducted at a private tertiary care hospital in Karachi for 10 years. In total, 26 patients fulfilled our inclusion criteria. All patients underwent a modified Crawford's procedure under general anesthesia. Results In this study, the male-to-female ratio was 1:1.5. In total, 17 (65%) patients had unilateral ptosis. The mean age of presentation was 7 ± 3 years. All of our patients had poor levator function (<5 mm excursion) with a mean of 3 mm and mean grade of ptosis of 4 ± 1.6 mm. The mean preoperative marginal reflex distance (MRD) was +1.8 ± 0.6 mm. In this study, the patients had a mean postoperative MRD of 4.2 ± 0.7 mm at the four-week follow-up. Conclusions Although Crawford's procedure gives promising results for ptosis correction, suturing the fascial sling to the tarsal plate ensures good anchorage and prevents relapse.

ABSTRACT

Globally, the surge in disease and urgency in maintaining social distancing has reawakened the use of telemedicine/telehealth. Amid the global health crisis, the world adopted the culture of online consultancy. Thus, there is a need to revamp the conventional model of the telemedicine system as per the current challenges and requirements. Security and privacy of data are main aspects to be considered in this era. Data-driven organizations also require compliance with regulatory bodies, such as HIPAA, PHI, and GDPR. These regulatory compliance bodies must ensure user data privacy by implementing necessary security measures. Patients and doctors are now connected to the cloud to access medical records, e.g., voice recordings of clinical sessions. Voice data reside in the cloud and can be compromised. While searching voice data, a patient's critical data can be leaked, exposed to cloud service providers, and spoofed by hackers. Secure, searchable encryption is a requirement for telemedicine systems for secure voice and phoneme searching. This research proposes the secure searching of phonemes from audio recordings using fully homomorphic encryption over the cloud. It utilizes IBM's homomorphic encryption library (HElib) and achieves indistinguishability. Testing and implementation were done on audio datasets of different sizes while varying the security parameters. The analysis includes a thorough security analysis along with leakage profiling. The proposed scheme achieved higher levels of security and privacy, especially when the security parameters increased. However, in use cases where higher levels of security were not desirous, one may rely on a reduction in the security parameters.
