A Comparative Study on Efficacy of Intraocular Pressure Lowering of Two Fixed-Dose Antiglaucoma Drug Combination Brinzolamide-Brimonidine Versus Latanoprost-Timolol in Primary Open-Angle Glaucoma and Ocular Hypertension

Purpose: To compare the efficacy of Brinzolamide-Brimonidine (BB) (1%+0.2%) with the gold standard Latanoprost-Timolol (LT) (0.005%+0.5%) in treating primary open-angle glaucoma (POAG) and ocular hypertension (OHT). Methods: A 1-year prospective study, spanning from May 2022 to May 2023, conducted at a tertiary eye-care hospital. Participants, aged 40-60, with a baseline intraocular pressure (IOP) >21 mm Hg, requiring a >30% reduction, were enrolled. Group A (n = 100) received BB, and Group B (n = 100) received LT. Outcomes were assessed at 1 month (IOP difference from baseline), 3 and 6 months (mean diurnal variations). Results: The mean age at presentation was 55.5 ± 4.5 years in Group A and 54.7 ± 4.2 years in Group B. At 1 month, Group A exhibited a mean IOP of 18.7 mm Hg, while Group B had 17.6 mm Hg, with no statistically significant difference (P = 0.53). No significant diurnal variation was observed in either group (P = 0.07). Target pressure was achieved in 88% of patients in Group A and slightly higher at 92% in Group B. Moreover, no serious side effects were reported, and compliance was higher in Group B (98%) compared to Group A (96%). Conclusion: Although LT showed slightly better and sustained IOP reduction, the difference was not statistically significant. Both BB and LT demonstrated comparable outcomes for managing POAG and OHT.

Ophthalmic manifestations as the first presenting feature in dengue fever: a 10-year study

Purpose: To report patients who first presented with various ocular manifestations and eventually ascertained to have underlying dengue. Methods: A prospective study was conducted at multiple tertiary eye-care centers in India from 2012 to 2022. Cases reporting initially with ocular features along with fever/past history of fever over the last two weeks or with clinical features of dengue were selected. After an ophthalmological examination, patients underwent complete serological and biochemical analysis and those with reduced platelet counts were evaluated for dengue. Results: Out of 564 cases, 15 patients were verified to be afflicted with dengue eventually. A rising trend of cases was seen every year and out of 15 cases, eight cases were reported during the Covid-19 pandemic (from 2020 to 2022), but were COVID-negative. 9 cases presented with acute redness followed by diminished vision. Seven cases presented a history of fever over the last few days and one had traveled from dengue endemic area. The various ocular presentations included subconjunctival hemorrhage, viral keratitis, anterior uveitis, sixth-nerve palsy, and vitreous hemorrhage. On serological examination, all 15 patients were detected to have low platelets. All cases responded well with supportive treatment and the ocular features subsided in all within a couple of weeks with good visual recovery. Conclusion: In a tropical nation, such as India, with endemic dengue zones and increasing figures of dengue lately, ophthalmologists must include dengue fever among the differential diagnoses in various ocular presentations like subconjunctival hemorrhage, viral keratitis, anterior uveitis, sixth nerve palsy, and vitreous hemorrhage. Abbreviations: DHF = dengue hemorrhagic fever, PCR = polymerase chain reaction, RT-PCR = real-time automated reverse transcriptase (RT-PCR), SD = standard deviation, MAC-ELIS = IgM antibodies capture enzyme-linked immunosorbent assay, RE = right eye, LE = left eye, CECT = Contrast-enhanced computed tomography.

A Survey on Relation of Menopause to Metabolic Syndrome - SAFOMS STUDY (South Asian Federation of Menopause Societies) - Interim Analysis

Background

Metabolic syndrome (MS) is a spectrum of disorders that includes dysglycemia, dyslipidemia, central obesity, and hypertension. South Asian Indians are more prone to harbor MS at a younger age compared to Caucasians. However, there is a lack of large-scale data correlating menopause to MS in South Asian settings.

Aims and Objectives

The study aimed to determine the prevalence of MS and its components in pre- and postmenopausal women. It also assessed the relationship of age, menopausal status, personal and family history, anthropometric parameters, and biochemical markers to MS.

Materials and Methods

It was an interim analysis of a multicountry cross-sectional study in the South Asian Federation of Menopause Society (SAFOMS) countries: India, Pakistan, Bangladesh, Nepal, and Sri Lanka conducted through both online and physical methods. The survey questionnaire consisted of questions about details of personal history, demographics, and family history related to MS. Anthropometric measurements such as height, weight, basal metabolic index (BMI), waist circumference, and blood pressure readings were noted. Relevant history, history of polycystic ovarian syndrome, hypertensive disorders of pregnancy, and vasomotor symptoms were enquired. Biochemical evaluation of markers associated with MS was undertaken.

Results

In this interim analysis, 638 women were recruited. Out of them, 406 (63.6%) women were premenopausal and 232 (36.4%) were postmenopausal. 392 (61.4%) women had MS, while 246 (38.6%) women did not have MS. Increasing age, BMI, and visceral adiposity (waist circumference) were significantly correlated with incidence of MS. Raised fasting blood sugar, hemoglobin A1C, total cholesterol, low-density lipoprotein, serum triglyceride, and reduced high-density lipoprotein levels were significantly associated with the incidence of MS in both pre- and postmenopausal women. Peri- and postmenopausal hot flashes, night sweats, and sleep disturbances were also significantly associated with MS. Personal history of hypertension, diabetes, and dyslipidemia were the strongest factors to be associated with MS with a significantly high odds ratio.

Conclusion

The study has highlighted the role of BMI and waist circumference as the first warning signs, which will encourage to go for regular biochemical screening through lipid profile and fasting blood glucose measurements. Our study is a stepping stone for all future studies for relation of menopause to MS.

Surgical Outcomes and Feasibility of Transvaginal Sacrospinous Ligament Fixation through Anterior Approach for Women with Pelvic Organ Prolapse

Introduction

Supporting vaginal vault or apex is a central component of primary therapy and to prevent recurrence of prolapse. This study aims to review the surgical outcomes and feasibility of the anterior approach following both sacrospinous fixation (SSF) and sacrospinous hysteropexy (SSHP) in a single center over a specific period. And also to review its impact on quality of life.

Materials and Methods

This was a retrospective study that included all women who underwent unilateral SSF or SSHP through anterior approach for pelvic organ prolapse (POP) from May 2021 to May 2023 after institutional ethical approval for the study. The anterior approach was undertaken in 47 patients which were included in final review. A retrospective case note review to assess urinary symptoms was undertaken at baseline and 3 months by urinary distress inventory 6 score. The main outcome measure was recurrence of prolapse, predominant compartment for prolapse, presenting complaints, concomitant surgeries performed, and associated urinary complaints.

Results

The mean age was 56.17 ± 11.95 years and the average body mass index was 26.12 ± 3.11 kg/m2. Except for 4 cases of SSHP, remaining women were postmenopausal at the time of surgery. Ten women presented with urinary complaints as their chief complaint. On examination, POP Quantification evaluation, 35 cases have Ba as leading point, 10 have Ap as their leading point and in two cases C was the leading point.

Conclusion

Anterior unilateral sacrospinous ligament fixation is a safe, effective strategy to treat POP and other concomitant surgery can also be well combined with it.

Prevent, curtail and mitigate ocular injuries: Proposal for designing an eye injury registry model for the Indian Armed Forces

This article aims to propose a design for Eye Injury Registry (EIR) model for Indian Armed Forces, to make ophthalmologists and non-ophthalmologists aware about the existence as well as the usefulness of such a registry. This is a perspective study. The EIR model for Armed Forces was designed based on the relevant sources in PubMed, Scopus and Embase including registries of pioneering countries like United States and Canada. A questionnaire based on the model dimensions was developed (Cronbach's alpha>0.7) and filled by 04 senior ophthalmologists in Armed Forces, all of who had a significant experience in dealing with various types of ocular trauma, to give expert opinions, which were then applied to the proposed model to finalize it. In Armed Forces, a registry and reporting on eye injury along with a systematic collection of standard data on eye injuries will help ophthalmologists in the successful prevention. Such a registry and its large database once formed will permit elaborate epidemiologic investigations, highlighting preventable sources of injury, emerging patterns of trauma in our services, and the best possible treatment protocols to be adopted, for successful outcomes. EIR in Armed Forces can help in the collection of eye injury data, thereby improving the quality-of-care and expansion of prevention strategies for ocular injuries. It is a step to make a truly effective data bank, which will be instrumental in combating such preventable ocular injuries and in turn go a very long way in achieving the final goal of preventing up to 90% of such injuries.

Universal slit-lamp-mounted mobile adapter with 20 D lens for fundus photography: "Litter to glitter"

Fundus photography is an arduous task as it involves using 90 D in one hand and a smartphone attached on an eyepiece of a slit-lamp biomicroscope in the other hand. Similarly, with a 20 D lens, the filming distance is adjusted by moving the lens or mobile forward or backward, which makes it difficult to adjust and focus the image in busy ophthalmology outpatient departments (OPDs). Moreover, fundus camera costs thousands of dollars. Authors describe a novel technique of performing fundus photography with a 20 D lens and a universal slit-lamp-mounted mobile adapter made from trash. By the use of this simple, yet frugal innovation, primary care physicians or ophthalmologists without a fundus camera can easily snap a fundus photo and subject it to digital analysis by retina specialists across the world. This will help in simultaneous ocular examination and fundus photos taken via mounted 20 D on a slit lamp itself and also reduce the need for unnecessary retina referrals to tertiary eye care centers.

An observational study on the presence of perilimbal conjunctival pigmentation in vernal keratoconjunctivitis

Purpose

To evaluate presence of perilimbal pigmentation (PLP) in Indian patients with vernal keratoconjunctivitis (VKC). Methods: A cross sectional study was conducted from 2019 to 2020 at a tertiary eye care center in Western Maharashtra, India. In this study, 152 cases of VKC were identified. The presence, type, color, and extent of PLP were recorded. The incidence of presence of PLP was calculated. Its correlations with severity and duration of VKC were analyzed using Wilcoxon-Mann-Whitney U test and Chi square test.

Results

Of 152 cases, 79.61% were males. Mean age at presentation was 11.4 ± 5.6 years. The characteristic PLP was present in 81 cases (53.29%; 95% confidence interval [CI]: 45.03%-61.42%; P < 0.001), of which 15 cases (18.5%) had this pigmentation in all the four quadrants. There was a significant difference between the groups with respect to quadrants involvement in terms of the extent of PLP in clock hours (χ² = 73.85, P < 0.001). However, the extent did not correlate with age (rho = 0.08, P = 0.487), sex (P = 0.115), time since onset in months (rho = 0.03, P = 0.77), duration of VKC and type or color of PLP (P = 0.12).

Conclusion

Perilimbal pigmentation seems to be a consistent clinical finding seen in a significant number of VKC cases. It may benefit ophthalmologists in treating VKC cases when the palpebral/limbal signs are elusive.

Pattern and distribution of neovascularization in proliferative diabetic retinopathy on fundus fluorescein angiography: A growing paradigm

Background

The objective of this study was to evaluate pattern and distribution of neovascularization of optic disc (NVD) and elsewhere (NVE) in proliferative diabetic retinopathy (PDR).

Methods

A cross-sectional study was conducted among freshly detected cases of PDR. Fundus fluorescein angiographic images of 61 eyes were assessed. Parameters studied for NVD were their number and location and for NVE were their number, location, type of leak, and distance from center of optic disc.

Results

Of 61 eyes, 29 eyes (47.5%) had NVD with a total of 49 leaks. Of these 49 NVD leaks, the maximum was concentrated in the superotemporal quadrant with 21 leaks (42.9%; 95%CI 28.8-57.8%). Of 61 eyes, 50 eyes (82%) had NVE with 97 leaks. Of 97 NVE leaks, 41 were found in the superotemporal quadrant (42.3%; 95%CI 32.3-52.7%). Maximum NVE was found within the circle of radius 3-6 mm centered on optic disc (p value = 0.001) with no leaks in central macula. Of 29 eyes with NVD, only 7 eyes had >1/3 area of disc involvement. Also, of 18 eyes with concurrent NVD and NVE, only 2 eyes had >1/3 area of disc involvement which is a high-risk characteristic of PDR.

Conclusion

Neovascular lesions have a predilection for superotemporal part for both NVD and NVE. NVE leaks were almost double the number of NVD leaks. Maximum NVE leaks were found at posterior pole with no central macular involvement. This study provides comprehensive data and further adds to knowledge of neovascularization for early diagnosis and management of PDR.

Eight years' experience in mobile teleophthalmology for diabetic retinopathy screening

Background

Screening for diabetic retinopathy in the community without compromising the routine work of ophthalmologists at hospitals is the essence of teleophthalmology. This study was aimed at investigating the efficacy of teleophthalmology practice for screening diabetic retinopathy from 2012 to 2020. It was also aimed at comparing the 2-year prevalence of camps organized by a district hospital in South India, as well as the footfall, reporting, follow-up, patient response, and diagnostic efficacy at these camps.

Methods

All patients with diabetes and unexplained vision deterioration attending the mobile camp units underwent non-dilated fundus photography. Patients underwent teleconsultation with the ophthalmologist at the district hospital, and those requiring intervention were called to the district hospital. Trends were studied for the number of patients reporting to the hospital. Patient satisfaction was recorded based on a questionnaire.

Results

A total of 682 camps were held over 8 years, and 30 230 patients were examined. Teleconsultation was done for 12 157 (40.21%) patients. Patients requiring further investigations, intervention for diabetic retinopathy, or further management of other ocular pathologies were urgently referred to the district hospital (n= 3293 [10.89%] of 30 230 examined patients). The severity and presence of clinically significant macular edema increased significantly with an increased duration of diabetes mellitus (P < 0.001). The percentage of teleconsultations showed an increasing trend over the years (P = 0.001). Similarly, considering trends of patients reporting to the hospital, the attrition rate decreased over the years (P < 0.05). A total of 10 974 of 12 157 (90.27%) patients who underwent teleophthalmic consultation were satisfied with the service.

Conclusions

Teleconsultations over the years showed an increasing trend, and the attrition rate decreased over the years. Teleophthalmology is achieving success in providing high-quality service, easy access to care, and in increasing patient satisfaction. Future studies on the role of teleophthalmology for other leading preventable causes of blindness seem possible and necessary.

Intrastromal voriconazole as successful adjunctive approach for recalcitrant deep fungal keratitis

Aim: To assess efficacy of intrastromal voriconazole (ISV) in the treatment of fungal keratitis non-responding to conventional antifungals. Methods: Eighteen patients with smear positive fungal keratitis, not responding to conventional topical/ systemic antifungal therapy up to 2 weeks, were included in the study. Afterwards, they were given ISV (50 µg in 0.1 ml) around the ulcer and continued to receive conventional antifungal therapy. Responses to treatment (decrease in size of the ulcer and infiltrates) were recorded daily for 3-days, at 1-week and every 2 weeks for 3-months, or until the ulcer had healed completely. Results: The mean age at presentation was 51 ± 17.83 years. The most common organism isolated was Fusarium (17/ 18), followed by Aspergillus (1/ 18). All the patients were successfully treated in terms of corneal healing, but one case did not improve in vision due to the existence of diabetic macular oedema. 6 patients improved after a single injection, 7 had to receive 2 and 5 improved after 3 injections. The mean number of injections in 17 treated patients was 1.94 ± 0.78. Moreover, the mean resolution time was 18.50 ± 6.25 days. The size of ulcer and height of hypopyon at presentation were noteworthy risk-factors linked to management outcomes. Deeper ulcers required a greater number of injections when compared to superficial ulcers. The mean best-corrected visual acuity improved from 0.94 to 0.25 at 3 months follow-up in all the patients. Conclusion: Intrastromal Voriconazole (50 µg/ 0.1 mL) appears to be an effective adjunct therapy in cases of recalcitrant deep fungal keratitis non-responding to conventional antifungals. Though, some may require repeated injections, timely ISV administration certainly reducing the need for tectonic/ therapeutic keratoplasty. Abbreviations: ISV = Intrastromal Voriconazole, AS-OCT = anterior-segment optical coherence topography, KOH = potassium hydroxide, BCVA = best-corrected visual acuity.

Vision related quality-of-life among patients with traumatic or non-traumatic ocular disease and its association with the Rights of Persons with Disabilities Act: Unveiling-the-hidden

Purpose

To assess vision-related quality of life (VrQoL) in cases with visual loss after ocular trauma (OT) or non-traumatic ocular disease (NTOD) using the National Eye Institute's 25-Item Visual Function Questionnaire 25 (VFQ-25) and its association with visual disability % (VD%) based on the Rights of Persons with Disabilities (RPwD) Act, 2016.

Methods

This was a prospective observational study conducted among cases with ocular morbidity in either or both eyes with a visual acuity of ≤6/24. VFQ-25 questionnaire was administered to measure QoL scores. Statistical analysis was done using the Statistical Package for the Social Sciences (SPSS) version 23. P < 0.05 was taken as significant.

Results

Eighty-eight respondents completed the questionnaire. Mean age of participants was 40.272 ± 9.35 years (range: 23-55 years). Forty-three (48.9%) and 45 (51.1%) participants had OT and NTOD, respectively. The most common cause was traumatic optic neuropathy (21.6%) followed by corneal causes (19.4%). Low visual QoL scores were reported in all the cases (57.52 ± 16.08). Between OT and NTOD, a significant difference in terms of age (P = 0.001) and general vision (P = 0.03) was seen. Lowest scores were for driving. Based on VD%, 77 cases had ≤40 and the rest had >40% VD with a significant difference in overall mean scores (P = 0.03), specifically in domains of general vision (P = 0.00), near activities (P = 0.00), and driving (P = 0.007). QoL was decreased in each subscale of ≤40%VD group, who faced the same predicament everywhere as by the cases with more disability.

Conclusion

Ocular morbidity is associated with low QoL, predominantly in domains like general vision, near activities and driving. The RPwD Act leaves out a huge population with VD without any government benefits. One might need to consider other vision-related factors also to provide them with social, psychological, and employment benefits.

Pattern of astigmatism using partial coherence interferometry in patients of different age groups undergoing cataract surgery

BACKGROUND

Astigmatism is a refractive error that accounts for 70% of refractive errors in the elderly population. It is important to be aware of the distribution, extent, and type of astigmatism in patients undergoing cataract surgery to guide in reducing postoperative spectacle dependency.

AIM

To study the demography, amount, and pattern of astigmatism using partial coherence interferometry in patients of different age groups undergoing cataract surgery.

MATERIALS AND METHODS

A cross-sectional observational study. Keratometry and demography data were collected for patients planned for cataract surgery at a tertiary care center between January 2018 and December 2019. It was done with noncontact partial coherence interferometry in patients above 50 years undergoing cataract surgery.

RESULTS

Out of 385 patients, 216 (56%) were males and 169 (44%) were females. Astigmatism was more common in males than females (P = 0.00). Against-the-rule (ATR) astigmatism was found in 262 cases (68%), while with-the-rule (WTR) astigmatism was seen in 87 cases (23%). ATR was more common than WTR (P = 0.00). The number of patients with ATR seems to be increased with aging eyes and was more common between 61 and 70 years of age group (P = 0.00). The total amount of astigmatism increased with increasing age (P = 0.00029) which was found to be significant. Frthermore, there was a gradual change of WTR to ATR astigmatism with aging eyes.

CONCLUSION

Two hundred and sixty-two cases (68%) had ATR astigmatism mainly seen in the age group of 61-70 years. Majority had astigmatism up to 1.0 D that can be easily managed by simple cost-effective keratorefractive procedures like on-axis incision, opposite clear corneal incision, and limbal relaxing incisions.

Neuromyelitis optica spectrum disorder with negative aquaporin-4 antibodies and positive anti-myelin oligodendrocyte glycoprotein antibodies: A case report

Neuromyelitis optica spectrum disorders (NMOSDs) are rare autoimmune-mediated chronic inflammatory disorders involving the central nervous system. The concept of NMOSDs has widened up recently. Its diagnostic criteria have broadened the knowledge of this particular disease including the atypical cases where antiaquaporin-4 antibody is negative and anti-myelin oligodendrocyte glycoprotein (MOG) antibody is positive. Myelin oligodendrocyte glycoprotein is a protein expressed on the outer surface of myelin sheath and oligodendrocytes of the central nervous system. The detection of anti-MOG-Ab is emerging evidence, and thus, research on the role of this antibody in such seronegative cases is still underway. Early diagnosis and adequate therapy is essential in such cases. Here, we report an eight-year-old girl who was diagnosed with NMOSDs and found to have anti-MOG antibodies in place of AQP-4 antibodies.

Impact on corneal morphology after cataract surgery with intracameral moxifloxacin in neglected hard cataracts

AIM

To evaluate corneal morphology after use of 0.5% intracameral moxifloxacin (ICM) in cataract surgery in patients who presented late with hard cataracts.

METHODS

Cross-sectional study conducted from June-2021 to December-2021 at a tertiary eye-care center. 90 patients over 60 years with high-risk characteristics for Covid-19, who presented late with higher grades of nuclear-sclerosis (NS), were included. They underwent phacoemulsification and 0.5%moxifloxacin (0.1 ml) was injected intracamerally at the end of surgery. Best-corrected visual acuity (BCVA), intraocular pressures (IOP), endothelial cell density (ECD), coefficient of variation in cell-area (CoV), hexagonality (Hex) and central corneal thickness (CCT) were measured preoperatively and postoperatively on day1, day7 and day30. Statistical analysis was done by Anova test. p-value<0.05 was considered significant.

RESULTS

Mean age of presentation was 65.26±8.3 years. Mean preoperative BCVA (1/60-to-6/60), IOP (16.7±2.3 mm of Hg), CCT (523.93±39.6µ), ECD (2547±302.08cells/mm2), Hex (47.04±5.7%) and CoV (37.57±3.9) changed to BCVA (6/9-to-6/6), IOP (17.5±2.1 mm of Hg), CCT (538.42±36.9µ), ECD (2388.40±339.25cells/mm2), Hex (44.44±5.6%) and CoV (39.09±4.5) at day30 postoperative. Average rate of change at day30 was increase in CCT (2.89%), ECD loss (6.4%), decrease in Hex (4.9%) and increase in CoV (4.6%), though clinically insignificant. No case of endophthalmitis or toxic-anterior segment syndrome seen.

CONCLUSION

0.5% moxifloxacin (0.1 ml) is safe as intracameral antibiotic to prevent postoperative infection in high-risk patients. The reported changes in the corneal parameters were within the range of any routine surgeries of hard senile cataracts. No specific effect could be attributed to ICM.

Outcomes of Descemet stripping endothelial keratoplasty in cases of corneal endothelial dysfunction

BACKGROUND

Automated microkeratome is commonly used to get donor lenticules for Descemet stripping endothelial keratoplasty (DSEK); however, manual dissection of donor lenticules is also being done with good outcomes.

AIM

The aim of this study was to describe the results of manual DSEK performed in cases of corneal endothelial dysfunction caused due to pseudophakic bullous keratopathy, iridocorneal endothelial syndrome, and postpenetrating keratoplasty graft failure.

MATERIALS AND METHODS

This was a retrospective observational study. The medical records of all patients with corneal decompensation who underwent DSEK at a tertiary care center performed by the same surgeon were reviewed. A standard DSEK with manually dissected donor lenticules was performed in all cases with the exception of the Descemet membrane not being removed in two cases. A comprehensive ophthalmic examination was performed preoperatively and at each postoperative visit in all patients.

RESULTS

Eight eyes of seven patients (four males and three females) were included. The mean age was 64.8 years (range, 49-74 years). The average follow-up was 10.9 months (range, 5-22 months). There was one case of primary graft failure which was managed by repeat DSEK. In the rest, corneas remained clear at the last follow-up. No rebubbling was done as none of the cases showed graft detachment. The preoperative best-corrected visual acuity (BCVA) was 20/2000 or less, and postoperatively, BCVA attained was 20/30 in four eyes and one eye achieved 20/80.

CONCLUSIONS

Manual DSEK performed in eyes with corneal decompensation allowed rapid restoration of corneal clarity while minimizing intraoperative and postoperative complications.

Lane-Hamilton syndrome - Is it really a needle in a haystack?

Introduction

The association of pulmonary hemosiderosis with celiac disease (Lane-Hamilton syndrome) is extremely rare.

Case Details

A five-year-old female child presented with fever, cough, breathlessness, and pallor for 20 days, without any previous history of recurrent lower respiratory tract infections, tuberculosis, or cardiac disease. There was no history of pica, chronic diarrhea, bleeding, or personal or family history of repeated blood transfusions. She had tachycardia, tachypnea, severe pallor, stunting, rickets, and bilateral fine lung crepitations. Peripheral smear and blood indices revealed dimorphic anemia. Anti-tissue transglutaminase IgA antibody levels were high (>200 U/mL) and the upper gastrointestinal endoscopy with duodenal biopsy confirmed the diagnosis of celiac disease. The child was discharged on a gluten-free diet (GFD) and oral hematinic, but her dietary compliance was poor. Interestingly, the child had persistent bilateral pulmonary infiltrates, which was initially attributed to congestive cardiac failure (CCF), which persisted even despite treatment. HRCT chest revealed interstitial thickening and bilateral alveolar shadows and bronchoalveolar lavage showed a few inflammatory cells. The child was readmitted four times with similar complaints and was given packed red cell transfusions. In the fourth admission, a lung biopsy was done, which revealed extensive pulmonary hemosiderosis. The patient was given a course of oral steroids for 6 weeks, with a gluten-free diet, following which both the anemia and the pulmonary infiltrates resolved.

Conclusion

Pulmonary hemosiderosis is an important cause of anemia in cases of celiac disease and may be misdiagnosed as CCF due to severe anemia. A strict GFD, with or without corticosteroids, can reverse the clinical and radiological picture.

Tuberculosis and neuromyelitis optica spectrum disorder: A conundrum

Purpose: Infectious atypical optic neuritis (AON), like tubercular, is a vision threatening condition with phenotypic overlap with Neuromyelitis Optica Spectrum Disorder (NMOSD). The overlapping neurological manifestations and negative AQP4-Ab-assay make it difficult to discover the primary cause of neuritis. Case presentation: We report two paediatric cases with NMOSD that did not fulfil the diagnostic criteria. Moreover, associated undiagnosed tuberculosis at the time of presentation and negative AQP4-Ab clouded the diagnosis and delayed the treatment. The first case was initially diagnosed with infectious optic neuropathy. By the time steroids were started, optic atrophy had already set in. The second case had optic neuritis, LETM, and intracranial-tuberculomas with no signs of pulmonary-tuberculosis with negative CSF-analysis. So, systemic steroids were started promptly. The history of LETM in both cases raised the suspicion of NMOSD. Conclusion: The importance of accurate clinical diagnosis and early intervention in cases of AON was emphasized in a limited resource country, that could potentially result in salutary visual outcomes, especially in the paediatric age group Abbreviations: AON = atypical optic neuritis, TB = tuberculosis, NMOSD = neuromyelitis optica spectrum disorder, LETM = longitudinal extensive transverse myelitis, AQP4-Ab = anti-Aquaporin-4 Antibodies, RE = right eye, LE = left eye, MRI = magnetic resonance imaging, CSF = cerebrospinal fluid, ATT = anti-tubercular treatment, DOV = diminution of vision.

Understanding esports industry and impact of Covid-19 on it: a review of literature

COVID-19 brought the whole world to a halt suddenly and forced it to go on social distancing & lockdown. COVID-19 has impacted every industry worldwide differently and mostly negatively, so we wanted to look at its impact on the ‘esports industry,’ especially in the Indian context. To understand the impact, we did a detailed literature review of academic papers, articles, industry reports to determine the current trend and predict possibility in the future. Our findings indicate that although the industry is facing issues, COVID-19 actually might have helped the esports industry in the long term and expedite its progress among the young generation. Once everything was done, we analyzed the complete literature review, and based on that; we listed out our findings, and based on our findings, we did a final evaluation. We reviewed the existing work of academicians, business reports, industry reports, trends captured by news/media organizations, and the current state of video games to find the trends & reasons which could help us solve our question.

Refractive and visual outcomes of plate-haptic toric intraocular lens implantation for astigmatic correction after uncomplicated microincision cataract surgery

Objective: To evaluate visual and refractive outcomes with plate-haptic toric intraocular lens implantation (ph-toric) after uncomplicated microincision cataract surgery (MICS) to correct moderate-to-severe astigmatism. Design: Prospective cross-sectional study. Methods: The study was conducted at a tertiary eye care center in New Delhi, India, on patients with visually-significant cataract and moderate-to-severe astigmatism (>1.00 diopters [D]). Preoperative parameters like visual-acuity, keratometry and astigmatism values and lens power calculation were noted. After MICS via 1.8 mm incision, a ph-toric IOL was implanted. The outcome measures noted were uncorrected and corrected distant visual-acuity (UDVA, CDVA), decrease in astigmatism and rotational stability. Follow-up was done on day 1, day 7, 1-month and 3-months postoperative. Results: This study involved 30 eyes of 30 patients. 27 patients (90%) gained UDVA of 6/ 9 or better. Out of these, 27 patients (90%) achieved CDVA of 6/ 6. Mean CDVA changed from 0.967 ± 0.101 postoperative to 0.176 ± 0.82 preoperatively (p<0.001). The mean preoperative astigmatism was 2.08 ± 0.59 D and the mean postoperative astigmatism was 0.35 ± 0.39 D. The mean correction achieved was 1.28 ± 0.32 D. Statistically significant (p<0.001) correction of astigmatism was observed by use of ph-toric IOL. The mean reduction in astigmatism was 84.16 ± 10.61 with excellent reduction in 43.3%. IOL rotation was <10 degrees in all the eyes. No complications were observed. Patients had satisfaction with the procedure and visual outcomes. Conclusion: Implantation of a plate-haptic toric IOL after uncomplicated MICS via 1.8 mm incision is a feasible and safe option in cataract cases with astigmatism to provide good visual and refractive outcomes. No major drawbacks were observed attributable to ph-toric IOL. Abbreviations: SIA - surgically induced astigmatism, D - diopters, MICS - microincision cataract surgery, ph-toric IOL - plate-haptic toric IOL, IOL - intraocular lens, UDVA - uncorrected distant visual acuity, CDVA - corrected distant visual acuity.

Unilateral simultaneous optic nerve and choroidal infiltration - unusual presentation of metastatic disease in breast carcinoma

Breast carcinoma metastasis can involve any ocular structures, but involvement of the optic nerve is extremely rare. Choroidal metastasis is usually multifocal as well as bilateral and occurs late. We report an unusual initial presentation of metastasis from breast cancer; unilateral infiltrative optic neuropathy with concurrent choroid metastatic deposits in an adequately treated middle-aged female. Our present case, wherein for the first time in the literature, we illustrated unilateral infiltrative optic neuropathy and choroidal metastatic deposits secondary to breast carcinoma, will increase our knowledge about the various potential ocular presentations of this relatively common malignant disease.

Minimally invasive techniques as a first line approach in the management of emphysematous pyelonephritis - A single centre experience

Context:

Emphysematous pyelonephritis (EPN) is a dangerous necrotizing infection of the kidney involving the diabetics with a high case fatality rate. Recent medical literature has shown shifting of treatment strategy from conventional radical approach to minimally invasive approach.

Aims:

The aim of our study was to assess the role of minimally invasive stepwise decompression techniques in the management of EPN and preservation of the renal unit.

Settings and Design

: This was a retrospective observational study conducted from June 2017 to April 2020 at a tertiary care centre.

Material and Methods:

We reviewed the hospital online records of 18 patients diagnosed with EPN for patient demographics, clinical profiles, co-morbidities, laboratory and, radiological investigations, surgical interventions performed and the outcomes. The severity of EPN was graded as per the Huang classification. Patients underwent surgical interventions as per the treatment protocol and response was assessed.

Statistical Analysis Used:

Descriptive statistics was applied.

Results:

Diabetes mellitus was present in 15 (83.3%) patients along with urinary tract obstruction in 8 (44.4%) patients. Flank pain (77.7%) was the most common presenting clinical feature while Escherichia coli (55.5%) were the most common causative organism. Most patients (50%) had Type- II EPN, all of which were managed successfully by minimally invasive procedures. In total seventeen patients (94.4%) responded well while one patient (5.5%) underwent nephrectomy with no mortality.

Conclusions:

Renal salvage in EPN requires multidisciplinary approach including the initial medical management followed by properly selected stepwise decompressive surgical techniques. Conservative management and decompression techniques have shown to improve patient's outcome, reducing the traditional morbidity associated with nephrectomy.

Effects of plant age on performance of the tropical perennial fodder grass, Cenchrus ciliaris L. subjected to elevated ultraviolet-B radiation

Abiotic stress, notably high ultraviolet-B (eUV-B), limit growth and productivity of many crop plants, but information on response of forage grasses to eUV-B radiation is rather limited. The present study was therefore conducted to increase our understanding of differential age-related responses on growth, metabolism and fodder quality of Cenchrus ciliaris-3108 (Buffel grass) to elevated UV-B (eUV-B: 7.2 kJ·m^-2 ·day^-1 ). Plant growth at both growth stages was notably reduced in response to eUV-B, except for the number of nodes and tillers at vegetative and reproductive stages. At anthesis, tillering increased due to the perennial habit of this plant, but leaf senescence reduced the number of leaves per tiller. Unlike ambient UV-B, eUV-B at the vegetative stage resulted in diversion of photosynthate for the formation of secondary metabolites (tannins and phenolics), providing dual protection from photooxidative damage and from herbivory. The forage biomass as well as quality showed a marked decline under eUV-B and relative nutritive value was reduced at both growth stages.

Comparative evaluation of a single 2.0-mm AO locking reconstruction plate with conventional miniplate osteosynthesis for treatment of linear non-comminuted fractures of symphysis and parasymphsis region of the mandible

The objective of the study was to evaluate and compare the relative efficacy of treating linear non-comminuted mandibular fracture of symphysis and parasymphysis region using single 2.0-mm AO locking reconstruction plate or using two conventional miniplates. In this study, 80 patients of symphysis or parasymphysis fracture were divided randomly in two equal groups and treated with open reduction and internal fixation using two 2.5-mm miniplates or with a single 2.0-mm AO locking reconstruction plate. Operating time in case of open reduction and fixation using a single 2.0-mm locking reconstruction plate was significantly less when compared to open reduction and fixation using two conventional miniplates. Both groups showed satisfactory fracture reduction and healing. No postoperative malocclusion was noted, and both groups showed comparable improvement in masticatory efficiency. In conclusion, fracture fixation using a single 2.0-mm AO locking reconstruction plate without use of a second plate at the superior border for treatment of linear non comminuted mandibular fracture in symphysis and parasymphysis region gives comparable results as with treatment by conventional miniplate system and provides significant savings in operating time, ease of use and decrease in amount of hardware incorporated in the body.

A Rare Pigmented Lesion of the Eyelid

This study aims to report a rare case of melanoacanthoma of the eyelid. Melanoacanthoma is very rare variant of seborrheic keratosis presenting as a rare benign pigmented lesion composed of both melanocytes and keratinocytes usually presenting over the head, neck, and trunk of elderly people. A 61-year-old female presented with 8 mm × 4 mm × 3 mm brownish black mass in her right lower lid for the past 4 years associated with itching. Clinical differential diagnosis of seborrheic keratosis and nevus was offered. The patient underwent shave biopsy, and biopsy tissue was sent for histopathological examination. A diagnosis of melanoacanthoma was made on histopathology. Melanoacanthoma of the eyelid is a rare entity, and one should consider in differential diagnosis of pigmented lesion of the eyelid mass.

The evolution of artificial hair implantation

From the beginning, artificial hair implantation has aroused a lot of interest, sometimes controversial, in the field of hair restoration. The artificial fiber must be of high quality and biocompatible. Biofibre® is a very fine fiber having diameter of 80 m. The standard length of this fiber is 15 or 30 cm, to satisfy multiple patient requests. They are available in 13 colors and 3 different shapes (straight, wavy and curly). Artificial hair implant is indicated in all (male and female) cases of androgenetic alopecia, especially for those who show dismal response to medical therapies and have poor donor area supply for hair transplantation. It has also shown good results to treat scars. One hundred thirty-three cases of androgenetic alopecia were treated with Biofibre® and followed-up for 3 years. A clinical evaluation was carried out after 1 month, 4 months and every other 4 months after the implant. The fiber loss was no more than 10% per year in 91.4% of the cases, 15% in 7.8% of the cases and 20% in 0.8% of the cases. 96.2% of patients declared themselves to be satisfied with the result of the implant while 3.8% declared to be not satisfied. To conclude, modern artificial hair implantation can be considered a safe and easy mode of hair restoration, for male and female patients, especially in donor depleted cases or when an immediate aesthetic result is required.

When potion becomes poison! A case report of flecainide toxicity

We report a 48-day-old female infant, who developed cardiac conduction abnormalities and seizures secondary to supratherapeutic doses of oral flecainide. Flecainide was started in this infant for treatment of supraventricular tachycardia. The drug was withdrawn with successful normalization of the QRS complex and no further recurrence of seizures. The Naranjo probability score for adverse drug reaction was 8, making the causality “probable.” The case restates an important message that physicians should be aware of the side effects of the drugs that they prescribe, especially of those drugs which have a narrow therapeutic window.

Sphincter of Oddi disorder (SOD): Is it necessary to investigate and treat?

Sphincter of Oddi disorder (SOD) is a part of functional gastrointestinal disorder which is a non-calculous obstructive disorder. This disease is more common in middle-aged women with a prevalence of around 1.5% but in patients with post-cholecystectomy syndrome (PCS) the prevalence rate is markedly higher (9-55%). This high variability maybe attributed to lack of uniformity in patient selection criteria, definition of SOD, and the diagnostic method used. Abdominal pain is the most common symptom occurring due to obstruction at the SO leading to ductal hypertension, ischemia from spastic contraction and hypersensitivity of papilla. Clinical diagnosis of SOD can be achieved by Rome III criteria. Various classifications are used (Milwaukee billiary and modified Milwaukee group classification) for billiary and pancreatic SOD. Not a single non-invasive method is diagnostic. Sphincter of Oddimanometry (SOM) is the gold standard method for evaluating and deciding the management of an SOD patient. The symptomatic relief rate varies from 55% to 95%, so risk-benefit ratio should be evaluated with each patient.

A clinico-histopathological study on skin appendageal tumors

Background: Skin Appendageal tumors are a large and diverse group of tumors that are commonly classified according to their state of appendageal differentiation: follicular, sebaceous, eccrine and apocrine. Objectives of this study were to study the clinic-epidemiological profile of skin appendageal tumors and to correlate the clinico-histopathological diagnosis.Materials and Methods: This was a retrospective and prospective study which included all cases of skin adnexal tumours diagnosed histologically during the period of f

"FISHed" out the diagnosis: A case of DiGeorge syndrome

Our patient presented with congenital heart disease (CHD: Tetralogy of Fallot), hypocalcemia, hypoparathyroidism, and facial dysmorphisms. Suspecting DiGeorge syndrome (DGS), a fluorescence in situ hybridization (FISH) analysis for 22q11.2 deletion was made. The child had a hemizygous deletion in the 22q11.2 region, diagnostic of DGS. Unfortunately, the patient succumbed to the heart disease. DGS is the most common microdeletion syndrome, and probably underrecognized due to the varied manifestations. This case stresses the importance of a detailed physical examination and a high index of suspicion for diagnosing this genetic condition. Timely diagnosis can help manage and monitor these patients better and also offer prenatal diagnosis in the next pregnancy.

Steady state temperature distribution in dermal regions of an irregular tapered shaped human limb with variable eccentricity

The investigators in the past have developed some models of temperature distribution in the human limb assuming it as a regular circular or elliptical tapered cylinder. But in reality the limb is not of regular tapered cylindrical shape. The radius and eccentricity are not same throughout the limb. In view of above a model of temperature distribution in the irregular tapered elliptical shaped human limb is proposed for a three dimensional steady state case in this paper. The limb is assumed to be composed of multiple cylindrical substructures with variable radius and eccentricity. The mathematical model incorporates the effect of blood mass flow rate, metabolic activity and thermal conductivity. The outer surface is exposed to the environment and appropriate boundary conditions have been framed. The finite element method has been employed to obtain the solution. The temperature profiles have been computed in the dermal layers of a human limb and used to study the effect of shape, microstructure and biophysical parameters on temperature distribution in human limbs. The proposed model is one of the most realistic model as compared to conventional models as this can be effectively employed to every regular and nonregular structures of the body with variable radius and eccentricity to study the thermal behaviour.

Responses of Beta vulgaris exposed to cadmium and zinc through soil drenching

The present study investigates the responses of Indian palak (Beta vulgaris L. cv. All Green H1) exposed to cadmium (Cd) and zinc (Zn) at growth, biochemical and physiological levels. The results revealed that Cd and Zn accumulation was higher in shoots as compared to the roots of B. vulgaris plants. The increased application rates of Zn in combination with Cd significantly reduced the accumulation of Cd in below and above ground parts of B. vulgaris, whereas it increased Zn accumulation. Treatments of B. vulgaris with Cd and Zn individually or in combination significantly reduced the leaf area, biomass, photosynthetic pigments, photosynthetic rate, Fv/Fm ratio and protein contents at p < 0.05. Contrary to this, lipid peroxidation, ascorbic acid, proline and thiol contents and peroxidase activity increased significantly as compared to control at p < 0.05. The results also revealed that the combined effectof Cd and Zn were more pronounced at higher concentrations as compared to other treatments. Thus, the present study suggests that Zn may be applied to Cd contaminated field to reduce Cd accumulation in plants. However, finding of a suitable dose and toxicity level of Zn must be worked out further its application.

MDR1 expression predicts outcome of Ph+ chronic phase CML patients on second-line nilotinib therapy after imatinib failure

In the face of competing tyrosine kinase inhibitors (TKIs), identification of chronic myeloid leukemia (CML) patients expecting favorable response to second-line treatment is warranted. At the time of imatinib resistance, the investigation of multidrug-resistance protein 1 (MDR1) and BCR-ABL yielded the following results: (i) Patients with high MDR1 transcript levels showed superior response at 48 months as compared with low-level MDR1 patients: major molecular response (MMR) in 41% vs 16% (P=0.014), complete cytogenetic response (CCyR) in 58% vs 39% (P=0.044), and progression-free survival (PFS) in 67% vs 46% (P=0.032). (ii) Patients with BCR-ABL(IS) <28% achieved higher MMR rates (48% vs 21%, P=0.009). (iii) PFS at 48 months was associated with in vitro resistance of BCR-ABL kinase domain mutations: 63% (no mutation) vs 61% (sensitive, intermediately sensitive or unknown IC50 (median inhibitory concentration)) vs 23% (resistant, P=0.01). (iv) Single-nucleotide polymorphisms (SNPs) at positions 1236 and 2677 were associated with higher MDR1 expression in comparison to wild type. (v) Nilotinib was able to impede proliferation of MDR1-overexpressing imatinib-resistant cells. High MDR1 gene expression might identify patients whose mode of imatinib resistance is essentially determined by increased efflux activity of MDR1 and therefore can be overcome by second-line nilotinib treatment.

Direct measurement of magnon temperature: new insight into magnon-phonon coupling in magnetic insulators

We present spatially resolved measurements of the magnon temperature in a magnetic insulator subject to a thermal gradient. Our data reveal an unexpectedly close correspondence between the spatial dependencies of the exchange magnon and phonon temperatures. These results indicate that if--as is currently thought--the transverse spin Seebeck effect is caused by a temperature difference between the magnon and phonon baths, it must be the case that the magnon temperature is spectrally nonuniform and that the effect is driven by the sparsely populated dipolar region of the magnon spectrum.

An unusual cause of central cyanosis in a nine-year-old boy

Pulmonary arteriovenous malformations are rare vascular anomalies which rarely present in childhood. We discuss a nine-year-old male child who presented with the classical triad of exertional dyspnea, cyanosis and clubbing since six years of age. Pulmonary arteriovenous malformation was suspected on chest radiography and was later confirmed on computed tomography scan. A bubble contrast echocardiography showed the presence of an extracardiac shunt. Pulmonary angiography was done to delineate the anatomy of the pulmonary vasculature and to plan embolization. The child has undergone two sittings of transcatheter coil embolization with improvement in oxygenation.

Growth, yield and tuber quality of Solanum tuberosum L. under supplemental ultraviolet-B radiation at different NPK levels

In many areas, decreases in the stratospheric ozone layer have resulted in an increase in ultraviolet-B (UV-B, 280-315 nm) radiation reaching the Earth's surface. The present study was conducted to evaluate the interactive effects of supplemental UV-B (sUV-B) and mineral nutrients on a tuber crop, potato (Solanum tuberosum L. var Kufri Badshah), under natural field conditions in a dry tropical environment. The nutrient treatments were the recommended dose of NPK (F(o)), 1.5 times the recommended dose of NPK (F(1)), 1.5 times the recommended dose of N (F(2)) and 1.5 times the recommended dose of K (F(3)). The response of potato plants to sUV-B varied with nutrient treatment and concentration. sUV-B adversely affected growth, yield and quality of tubers, causing an increase in reducing sugars in the tubers and thus reducing the economic value. Growth and fresh weight of tubers was maximal with sUV-B at 1.5 times recommended NPK, but the dry weight of tubers were highest with the recommended NPK dose. Reducing sugar content was lower in potato plants treated with sUV-B and the recommended NPK than with sUV-B and 1.5 times the recommended NPK. This study thus clearly shows that growing potato with 1.5 times the recommended NPK or 1.5 times the recommended dose of N/K does not alleviate the sUV-B induced changes in yield and quality of tubers compared to the recommended NPK dose.
