Microkeratome chronicles: Management of a free flap

Background: In LASIK (laser in situ keratomileusis), a hinged corneal flap is made, which enables the flap to be lifted and the excimer laser to be applied to the stromal bed. If the hinge of the corneal flap detaches from the cornea, the flap is called a free cap. A free cap is a rare intra-operative complication of LASIK most commonly associated with the use of a microkeratome on corneas with flat keratometry, which predisposes to a small flap diameter. Free caps are preventable and treatable. Rarely does the complication lead to a severe or permanent decrease in visual acuity. Purpose: As free caps are avoidable, prevention is critical. Our video gives some tips and tricks on how to avoid a free flap and also focuses on how to manage a cut through a free flap. Synopsis: If a free cap is created, the surgeon must decide whether to continue with excimer laser ablation or to abort the procedure. When to abort: If the stromal bed is irregular, the flap is replaced without applying laser ablation. Without ablation, generally, there is no change in refractive error or significant loss of visual acuity. When to continue: If the stromal bed is regular and the cap is of normal thickness, the surgeon may proceed with ablation. To prevent desiccation, the free cap should be handled with caution and should be placed on a drop of balanced salt solution. The free cap should be placed epithelial facing up, along with a bandage contact lens. The endothelial cell pump mechanism typically allows the cap to re-adhere tightly. Highlights: Risk factors for a free cap are generally anatomic or mechanical. Especially in flat corneas, an appropriate ring and stop size should be chosen looking at the nomogram on the basis of the keratometry values. Deep orbits and deep-seated eyes should be looked for as PRK is a better option in such cases. Inadequate suction should be dealt with a lot of care, and once this is done, the vacuum should be stopped. Re-docking of the microkeratome with suction can be done again. Prior testing of the microkeratome and a good verbal anesthesia are a few more such important points to be pondered upon. This video gives us such tips and is a comprehensive video for a novice surgeon performing microkeratome LASIK

Determination of a cut-off value for the serological diagnosis of scrub typhus by detecting anti-Orientia tsutsugamushi immunoglobulin M

Background & objectives: The diagnosis of scrub typhus (ST) is usually done using enzyme-linked immunosorbent assay (ELISA) due to its ease of performance and reading objectivity. The cut-off value for ELISA needs to be calculated for each geographical location as it depends on zonal endemicity of the disease. This study was, therefore, undertaken to calculate the pan-India cut-off for anti-Orientia tsutsugamushi (OT) immunoglobulin M (IgM) by ELISA. Methods: Samples from cases (cases of ST) and controls (voluntary, consenting, healthy adults) were collected by a network of 29 laboratories across India and tested for anti-OT IgM by immunofluorescence assay (IFA), the considered gold standard test. These samples were retested by ELISA for anti-OT IgM and their optical densities (ODs) were used for cut-off estimation by receiver operating characteristic (ROC) curve. Results: Anti-OT IgM ELISA ODs from 273 controls and 136 cases were used for the cut-off estimation. The ODs of the anti-OT IgM ELISA on healthy individuals and those of confirmed ST cases ranged from 0.1 to 0.75 and 0.5 to 4.718, respectively. ROC curve-based cut-off for ELISA was calculated as 0.554 at a sensitivity of 95.2 per cent and specificity of 95.1 per cent. A value of >1 was noted to have a specificity of 100 per cent in diagnosing ST. Interpretation & conclusions: The cut-off calculated for India was similar to the previous cut-off that was used until now.

Clinical characteristics, etiological profile, treatment and long term outcomes in patients with non ischemic systolic heart failure; Himachal Pradesh heart failure registry (HP–HF registry)

Background: The data on clinical characteristics, treatment practices and out comes in patients with Nonischemic Systolic Heart Failure (NISHF) is limited. We report clinical characteristics, treatment and outcomes in patients with NISHF. Methods: 1004 patients with NISHF were prospectively enrolled and their demographics, clinical characteristics, and treatment were recorded systematically. Patients were followed annually for a median of 3 years (1 year to 8 years) for allcause death, major adverse cardiovascular events (MACE); composite of all-cause death, hospitalization of heart failure, and or for stroke. Results: Patients of NISHF were middle-aged (58.8±16.2 years) population with severely depressed left ventricular ejection fraction (29.3±7.02%) and 31.1% had symptoms of advanced Heart failure. Hypertension (43.6%), obesity and or overweight (28.0%), Diabetes (15.0%), and valvular heart disease (11.8%) were the common risk factors. The guideline directed medical treatment was prescribed in more than 80% of the study cohort. Incidence of all cause death and MACE was 7 (6.8, 8.8) per 100 person years and 11(10, 13) per 100 person years respectively. The cumulative incidence of deaths and MACE was 35% (30%, 40%) and 49% (44%, 53%) at 8 years of follow-up. Conclusions: Patients of NISHF were middle-aged population with severely depressed LV systolic function with significant incident morbidity and mortality. Early detection of risk factors and their risk management and enhancing the use of guideline directed treatment may improve the outcomes. Keywords: Non-ischemic systolic heart failure, risk factors, outcomes, guideline directed treatment

Treatment of grade four hemorrhoids in a patient with acute myeloid leukemia with severe thrombocytopenia by laser hemorrhoidopexy: A case report

Here, we present the case of a 66-year-old female patient with acute myeloid leukemia and severe thrombocytopenia who came with the complaints of painful per anal mass and bleeding per rectum for 1 year. The patient is a known case of hypertension, and diabetes mellitus and has received three cycles of chemotherapy with decitabine. On examination, she was found to have fourth-degree hemorrhoids at 3, 7, and 11 oclock positions with acute edematous changes. We successfully treated this patient with laser hemorrhoidopexy, whereby laser energy was delivered to each hemorrhoidal cushion. While lasers for the successful treatment of grade 2 and 3 hemorrhoids are well documented in the literature, we successfully treated this patient with prolapsing fourth-degree hemorrhoids with just laser energy delivery. With these results, we would also like to consider laser hemorrhoidopexy as an effective treatment option for four-degree hemorrhoids for which open Milligan–Morgan hemorrhoidectomy and stapler hemorrhoidectomy are currently considered treatment options

Incidence, determinants, and outcomes of recovered left ventricular ejection fraction (LVEF) in patients with non-ischemic systolic heart failure; a hospital-based cohort study

Background: The data on incidence of recovered Left Ventricular Ejection Fraction (LVEF) and outcome in patients with non ischemic systolic heart failure is limited. We report the incidence, determinants and mortality in patients with recovered LVEF. Methods: The 369 patients with HFrEF with LVEF of less than 40% of non ischemic etiology with available follow up echocardiography study at one year were enrolled. The baseline data of clinical characteristics and treatment was recorded prospectively and were followed up annually for mean of 3.6 years (range 2 to 5 years) to record all cause death and LVEF measured echocardiographically. The recovered, partially recovered and no recovery of LVEF was defined based on increase in LVEF to 50% and more, 41% to 49% and to persistently depressed LVEF to 40% or lower respectively. Results: The LVEF recovered in 36.5%% of the cohort at 5 years. The rate of recovery of LVEF was slower in patients with no recovery of LVEF at one year compared to cohort with partially recovered LVEF (18% vs.53%) at five year. The Baseline LVEF was significantly associated with recovered LVEF, odd ratio (95% C.I.) 1.09(1.04, 1.14). The cumulative mortality at five years was significantly lower in cohort with recovered LVEF (18.1% vs. 57.1%). Conclusions: One third of the patients had recovered LVEF and was significantly associated with baseline LVEF and lower mortality rate.

Slit-lamp assisted TORic Marker (STORM): A novel corneal axis marker

Background: Toric Intraocular lenses (IOLs) are supposed to be aligned at a particular axis for spectacle?free vision for distance. The evolution of topographers and optical biometers has made it quite achievable for us to aim the target. However, the result sometimes remains unpredictable. A big aspect of this depends on the preop axis marking for toric IOL alignment. Errors in axis marking have been reduced recently with the array of different toric markers in the market, but still we see postoperative refractive surprises due to faulty marking. Purpose: In this video, we present a novel slit lamp–based toric marker innovation, STORM, which gives us a hands?free approach to a reliable and accurate axis marking on the cornea. The axis marker is a simple modification to our age?old marker, with the advantage of no touch and slit?lamp assistance, which will make it error free and easy to use. Synopsis: The present innovation answers the problem statement of stable, economical, and accurate marking solution. Many a times, hand?holding devices create inaccurate and stressed condition while marking the cornea before corneal surgery. Highlights: The invention can be used for marking of accurate and easy astigmatic axis of a toric IOL preoperatively, that is, before the surgery. If the appropriate device is used to mark the cornea, it would impact the outcome of surgery. This device also makes the patient and the surgeon comfortable to mark the cornea with accuracy and without hesitation

Efficacy and safety of knotless barbed sutures in capsular closure following distal femur fracture fixation / Eficácia e segurança das suturas farpadas sem nós no fechamento capsular após fixação de fratura distal do fêmur

ABSTRACT Introduction: Good wound closure is an important step in management of distal femur fracture to prevent infection and faster rehabilitation. Knotless barbed sutures can save time and distribute wound tension evenly. However, its role in terms of functional outcome, closure time, and postoperative complications has not been studied in a distal femur fracture. Material and methods: A total of 47 patients aged more than 18 years of distal femur fracture treated with distal femur locking plate were randomized either into either barbed or traditional suture groups. in the barbed group, capsular wound closure was carried out with 2-0 bidirectional barbed knotless sutures (Quill SRS® PDO, Angiotech, Vancouver, BC, Canada). In patients assigned to group B, capsular closure was done with 1-0 Vicryl® (Ethicon inc. Somerville, NJ) and 5-0 Ethibond® alternatively. Results: The mean flexion at the knee joint was 105.7±15.6 degrees in the study group while it was 110.4±13.7 in the control group (p= 0.2133). Mean estimated closure time was significantly shorter in the study group as compared to the control group (p<0.05). Cases of needle prick injury were higher in traditional suture group. Patients developed stitch abscess and superficial infection in both groups. However, the difference in incidence between the two was not statistically significant Conclusion: Barbed suture is an efficient method of wound closure. It reduces wound closure time with similar complication rate as with use of conventional sutures. Evidence Level II; Randomized Clinical Trial.

RESUMO Introdução: O fechamento adequado da ferida é um passo importante no manejo da fratura distal do fêmur a fim de evitar infecção e permitir uma rápida reabilitação. Suturas farpadas sem nós podem poupar tempo e distribuir uniformemente a tensão da ferida. Entretanto, seu papel em termos de resultado funcional, tempo de fechamento e complicações pós-operatórias não tem sido analisado em casos de fratura distal do fêmur. Material e métodos: Um total de 47 pacientes com mais de 18 anos de idade com fratura distal do fêmur tratados com placa de fixação distal do fêmur foram aleatorizados em grupos de sutura farpada ou tradicional. No grupo de farpados, o fechamento da ferida capsular foi feito com suturas sem nós farpados bidirecionais 2-0 (Quill SRS® PDO, Angiotech, Vancouver, BC, Canadá). Em pacientes designados para o grupo B, o fechamento capsular foi feito com Vicryl®1-0 (Ethicon inc. Somerville, NJ) e Ethibond® 5-0 respectivamente. Resultados: A flexão média na articulação do joelho foi de 105,7±15,6 graus no grupo de estudo e 110,4±13,7 no grupo controle (p= 0,2133). O tempo médio estimado de fechamento foi significativamente menor no grupo de estudo em comparação com o grupo controle (p<0,05). Os casos de ferimento por perfuração da agulha foram maiores no grupo de sutura tradicional. Os pacientes desenvolveram abscesso de pontos e infecção superficial em ambos os grupos. Entretanto, a diferença na incidência entre os dois não foi estatisticamente significative Conclusão: A sutura farpada é um método eficiente para o fechamento de feridas. Ele reduz o tempo de fechamento das feridas com uma taxa de complicação semelhante à utilização de suturas convencionais. Evidência Nível II; Ensaio Clínico Randomizado.

Serum estradiol levels decrease after oophorectomy in transmasculine individuals on testosterone therapy / 亚洲男科学杂志(英文版)

Transmasculine individuals, considering whether to undergo total hysterectomy with bilateral salpingectomy, have the option to have a concomitant oophorectomy. While studies have evaluated hormone changes following testosterone therapy initiation, most of those patients have not undergone oophorectomy. Data are currently limited to support health outcomes regarding the decision to retain or remove the ovaries. We performed a retrospective chart review of transmasculine patients maintained on high-dose testosterone therapy at a single endocrine clinic in Vancouver, British Columbia, Canada. Twelve transmasculine individuals who underwent bilateral oophorectomy and had presurgical and postsurgical serum data were included. We identified 12 transmasculine subjects as controls, who were on testosterone therapy and did not undergo oophorectomy, but additionally matched to the first group by age, testosterone dosing regimen, and body mass index. There was a statistically significant decrease in the estradiol levels of case subjects postoophorectomy, when compared to presurgical estradiol levels (P = 0.02). There was no significant difference between baseline estradiol levels between control and case subjects; however, the difference in estradiol levels at follow-up measurements was significant (P = 0.03). Total testosterone levels did not differ between control and case subjects at baseline and follow-up (both P > 0.05). Our results demonstrate that oophorectomy further attenuates estradiol levels below what is achieved by high-dose exogenous testosterone alone. Correlated clinical outcomes, such as impacts on bone health, were not available. The clinical implications of oophorectomy versus ovarian retention on endocrinological and overall health outcomes are currently limited.

Apalutamide for metastatic castration-sensitive prostate cancer: final analysis of the Asian subpopulation in the TITAN trial / 亚洲男科学杂志(英文版)

The final analysis of the phase 3 Targeted Investigational Treatment Analysis of Novel Anti-androgen (TITAN) trial showed improvement in overall survival (OS) and other efficacy endpoints with apalutamide plus androgen deprivation therapy (ADT) versus ADT alone in patients with metastatic castration-sensitive prostate cancer (mCSPC). As ethnicity and regional differences may affect treatment outcomes in advanced prostate cancer, a post hoc final analysis was conducted to assess the efficacy and safety of apalutamide in the Asian subpopulation. Event-driven endpoints were OS, and time from randomization to initiation of castration resistance, prostate-specific antigen (PSA) progression, and second progression-free survival (PFS2) on first subsequent therapy or death. Efficacy endpoints were assessed using the Kaplan-Meier method and Cox proportional-hazards models without formal statistical testing and adjustment for multiplicity. Participating Asian patients received once-daily apalutamide 240 mg ( n = 111) or placebo ( n = 110) plus ADT. After a median follow-up of 42.5 months and despite crossover of 47 placebo recipients to open-label apalutamide, apalutamide reduced the risk of death by 32% (hazard ratio [HR]: 0.68; 95% confidence interval [CI]: 0.42-1.13), risk of castration resistance by 69% (HR: 0.31; 95% CI: 0.21-0.46), PSA progression by 79% (HR: 0.21; 95% CI: 0.13-0.35) and PFS2 by 24% (HR: 0.76; 95% CI: 0.44-1.29) relative to placebo. The outcomes were comparable between subgroups with low- and high-volume disease at baseline. No new safety issues were identified. Apalutamide provides valuable clinical benefits to Asian patients with mCSPC, with an efficacy and safety profile consistent with that in the overall patient population.

True Hermaphroditism in a Goat – A case report

A four-month-old prepubertal female goat was presented to RVP IVRI Bareilly, with the history of an abnormal growth in the vulva. On clinical examination the growth was found as prominent clitoris, and two peanut sized soft structures were palpable at the subcutaneous in inguinal region. Transabdominal B mode real time ultrasound of inguinal region revealed testis like morphology and presence of uterus and ovaries structures subcutaneously. The case was subsequently diagnosed as hermaphrodism.

Comparison of different endophthalmitis prophylactic measures in cataract surgery - An analysis of 2.4 lakh cases

Purpose: To compare different endophthalmitis prophylaxis methods adopted in cataract surgery (manual small-incision cataract surgery and phacoemulsification) between the years 2013 and 2021 in the community eye care section of a tertiary eye care hospital in South India and report their outcomes. Methods: All cataract surgeries performed from January 2013 to December 2021 (2,46,874 surgeries) at a single center were included in this retrospective study. The different endophthalmitis rates with each regimen were analyzed and evaluated. Results: 70,081 surgeries were performed from January 2013 to February 2015, where Tobramycin was added to Balanced Salt Solution (BSS) (Group A). From March 2015 to January 2017, 63,245 surgeries were performed when intracameral Moxifloxacin was given (Group B). From February 2017 to December 2021, 1,13,548 surgeries were performed were Amikacin was added to BSS (Group C). In total, 42 cases of postoperative endophthalmitis were reported during the study period (0.02%). There was no significant difference in the endophthalmitis rates between groups A and B (P = 0.4152); however, there was a significant decrease in endophthalmitis rates in group C when compared with group A (P = 0.04) and group B (P = 0.006). Conclusion: There was a significant reduction in the rates of endophthalmitis following the addition of amikacin in irrigating BSS. Nocardia was one of the predominant organisms isolated from these endophthalmitis patients. This is the first single-center study to report a comparative analysis of different endophthalmitis prophylactic measures in a community eye care set up with a high incidence of Nocardia endophthalmitis prevented with amikacin in BSS irrigating solution.

Polyalanine polymorphism in the signal peptide of Glutathione peroxidase 1 (GPX1) gene & its association with osteoporosis

Background & objectives: Osteoporosis is a systemic skeletal disease, characterized by a low bone mass leading to increased bone fragility and hence, a greater susceptibility to the risk of fracture. Since age-related oxidative stress is one of the factors that has been implicated in developing low bone mineral density (BMD), leading to osteoporosis, this study wanted to explore the expression of antioxidant enzymes in individuals with osteoporosis. The present study focused on mapping polymorphism in an important antioxidant enzyme glutathione peroxidase 1 (GPx1) among osteoporosis and healthy Asian Indians. Methods: Dual-energy X-ray absorptiometry was used to assess BMD of individuals and was classified into normal (n=96) and osteoporotic (n=88) groups. Biochemical parameters such as vitamin D, total oxidant status (TOS), and GPx1 enzyme activity were estimated from plasma samples of recruited individuals. Quantitative real-time qRT-PCR was carried out using GAPDH as an endogenous control. Genomic DNA was isolated from whole blood, and polymorphisms were evaluated by sequencing. Results: The BMD was lower in osteoporotic individuals, and further analysis of biochemical parameters indicated significantly low 25-hydroxy vitamin D and GPx1 with higher TOS levels in osteoporotic as compared to healthy individuals. Furthermore, qRT-PCR revealed low expression of GPX1 in osteoporotic individuals. GPX1 sequence analysis of the promoter and two exons revealed the lower frequency of five alanine repeats in the osteoporotic individuals. Interpretation & conclusions: In this study, the in silico analysis revealed the lower frequency of five alanine repeats in exon 1 of GPX1 and high TOS to be associated with osteoporosis. However, no polymorphism was found in exon 2 of GPX1 among the two study groups.

Ten commandments for biometry in tricky situations

Background: Recently, the number of litigations on cataract surgeons has increased. Because of the increasing ambitions of surgeons and demands for a spectacle?free life, the incidence of unhappy patients is at an all?time high. To an ophthalmologist, the fruits of a good surgery are dependent largely on their skills. However, more importantly, the roots of good results of a surgery are laid by a perfect IOL (intraocular lens) power calculation. Inaccurate biometry is one of the major reasons for unhappy patients, especially in some challenging scenarios. Purpose: To hit the bull’s eye, as far as target refraction is concerned, it is necessary to understand the benefits and limitations of currently available cutting?edge technology and formulae and apply them to the cataract surgery practice. The aim of the video is to familiarize modern?day ophthalmologists to these situations to achieve a perfect IOL power calculation. Synopsis: Using a step?by?step approach, we decoded biometry in special scenarios like poor cornea, ocular surface disorders, dry eyes, toric IOL calculation, cases with posterior corneal astigmatism, irregular corneas like keratoconus, pellucid marginal degeneration, post Lasik ectasia and penetrating keratoplasty. In this video we tried to address the solution to these special conditions and how to attain target refraction in such cases. A few more issues are addressed like biometry post retina surgery, very dense cataract where it is difficult to obtain axial length, and cases with extreme axial lengths. Highlights: In this case?based approach, with relevant example, we tried to provide solutions for biometry in tricky scenarios like poor cornea, biometry post refractive surgery, dense cataracts, and cataract post retinal surgery. On following these commandments, not only will the litigations stop but our patients will be happier as well

Insight into strigolactone hormone functions in plant parasitic weeds: a regulatory perspective

The strigolactones (SLs) are plants hormones that have multiple functions in architecture and development. The roles of SLs in shoot branching and stem secondary growth of autotrophic plants are established. SL is also involved in the interaction between root parasitic plants and their host plants. SLs are exudates by the root of the host plant in search of a fungal partner for symbiotic association, while parasitic plants utilize this facility to detect the host root. The first formed tubercle of Philapanhche, whose germinations are driven by host-derived SLs, exudates parasitic derived SLs (PSLs) and could encourages germination of the adjacent parasitic seeds, resulting in parasite cluster formation. The existence of aboveground spikes in clusters suggests an intriguing approach for increasing parasite population by amplifying PSLs, which result in massive parasitic seed germination. PSLs probably have a role in the increased branching of Broomrapes opposing the host plant, resulting in the parasites' clustered appearance aboveground. This review highlights the distinct roles of SLs and PSLs, and their potential role in host-parasitic interaction.

Cocktail Inferno – Multiple Sclerosis with Type 2 Diabetes Mellitus in a Patient with Lepromatous Leprosy

Co-occurrence of multiple sclerosis with type 2 diabetes mellitus with lepromatous leprosy is rare. We hereby report a case of multiple sclerosis with type 2 diabetes mellitus with lepromatous leprosy in a middle-aged female. She was clinically diagnosed as having multiple sclerosis with type 2 diabetes mellitus and presented with fever, ENL and neuritis. Her MRI reports were normal but she had a positive slit-skin smear and skin biopsy as lepromatous leprosy. Proceeding with this diagnosis, she was treated with baclofen for spastic bladder, antibiotics for urinary tract infection, oral hypoglycemic agents and oral steroids with multibacillary treatment for leprosy with type 2 reactions. She responded well and currently is being followed-up.

Histological Spectrum of Clinical Kidney Disease in Type 2 Diabetes Mellitus Patients with special Reference to nonalbuminuric Diabetic Nephropathy: A Kidney Biopsy-based Study

Background: Diabetic nephropathy (DN) is an important and catastrophic complication of diabetes mellitus (DM). Kidney disease has heterogeneity in histology in diabetes patients and includes both diabetic kidney disease (DKD) (albuminuric or nonalbuminuric) and nondiabetic kidney disease (NDKD) either in isolation or in coexistence with DN. Diabetic nephropathy is hard to overturn. While NDKD is treatable and reversible. Materials and methods: We enrolled a total of 50 type 2 diabetes mellitus (T2DM) patients with clinical kidney disease, of both genders and age >18 years, who underwent kidney biopsy from October 2016 to October 2018. Patients with proteinuria <30 mg per day were excluded from the study. The indications of the renal biopsy were nephrotic syndrome (NS), active urinary sediment, rapid decline in renal function, asymptomatic proteinuria, and hematuria. Result: A total of 50 (males: 42 and females: eight) patients with T2DM who underwent kidney biopsy were enrolled. The clinical presentation was: NS 26 (52%), chronic kidney disease (CKD) 11 (22%), asymptomatic proteinuria and hematuria six (12%), acute kidney injury (AKI) four (8%), and acute nephritic syndrome (ANS) three (6%). Diabetic retinopathy (DR) was noted in 19 (38%) cases. Kidney biopsy revealed isolated DN, isolated NDKD, and NDKD superimposed on DN in 26 (52%), 14 (28%), and 10 (20%) cases, respectively. Idiopathic membranous nephropathy (MN) (4) and amyloidosis (2) were the most common forms of NDKD, whereas diffuse proliferative glomerulonephritis (DPGN) was the main form of NDKD superimposed on DN. Diabetic nephropathy was observed in 15 (79%) cases in presence of DR and also in 11 (35.5%) cases even in absence of DR. Of eight patients with microalbuminuria four (50%) cases have biopsy-proven DN. Conclusion: About 48% of patients had NDKD either in isolation or in coexistence with DN. Diabetic nephropathy was found in absence of DR and in patients with a low level of proteinuria. The level of proteinuria and presence of DR does not help to distinguish DN vs NDKD. Hence, renal biopsy may be useful in selected T2DM patients with clinical kidney disease to diagnose NDKD.

Hocus pocus: Breaking the curse of presbyopia

Background: Research and awareness on refractive solutions for presbyopia, commonly known as the “Curse of the 40’s,” is essential as a large population in the world suffer from vision impairments. Population-based surveys have shown that one billion people in the world are in presbyopic age. Purpose: Many structural and physiological changes occur in the eye with the onset of presbyopia, including the decrease in amplitude of accommodation. At present, various static and dynamic techniques have been attempted to give presbyopes good vision at near-, intermediate-, and far-viewing distances. The aim of the video is to familiarize the modern-day ophthalmologists to these modalities. Synopsis: In this video, we tried to summarize the indications and contraindications of presbyopic laser. Preoperative investigations like dominance testing and micro monovision testing are described. The role of neuroadaptation and patient counselling is emphasized. Static techniques described in the video include spectacles, contact lenses, surgical options like corneal inlays and onlays, corneal laser ablation, conductive keratoplasty, corneal implant lenses, INTRACOR and IOLs. Dynamic presbyopia correction (accommodative) is always surgical. This is split into lenticular (accommodating IOLs, piggyback, lens refilling, lentotomy) and scleral treatment (laser-assisted presbyopia reversal and scleral expansion bands). Highlights: The types of corneal laser ablation, which is otherwise very confusing, is elaborated in a step-wise manner here. The difference in approach of PresbyLasik (Nidek), Presbyond (Zeiss) - Laser Blended Vision, PresbyMax (Schwind), INTRACOR (Technolas) are explained with examples. Each approach has its pros and cons. Our challenge as a surgeon is to identify the best combination for the patient. This video illustrates the treatment options which can help break the curse of presbyopia

VANISHING MOUNTAINS: A STUDY OF ILLEGAL MINING IN THE ARAVALLIS OF SOUTH-WESTERN DISTRICTS OF HARYANA AND ITS EFFECT ON THE PHYSICAL ENVIRONMENT AND HUMAN LIFE

Illegal mining activities have been rampant since decades. These activities have literally changed the face of the landscape. The mountains have disappeared, surface have been left dotted with deep mining pits, villagers have to live a substandard life due to the negative effects of mining in the form of decreased water quality, poor air quality, mining related accidents, damaged houses because of stone blasting and much more. The authorities have turned a blind eye towards the common man's problem and thus the residents of nearby villages are left with no choice but to live under silence. The unscientific and illegal mining practices in the south- west region of Haryana in the districts of Mehandargarh, Dadri and Bhiwani has altered the physical landscape and affected the socio cultural life of nearby villages to a great extent. The study is a step in the direction of describing how an anthropogenic activity if done without any rules and order and in unscientific manner can affect the environment to unimaginable

Management of Hypertension in Patients with Diabetes: A Comprehensive Review of the Perceptions and Practices of Health Care Providers in India

Objectives: This study evaluated the perception and practices of health care providers (physicians, diabetologists, and endocrinologists) regarding the treatment of hypertension in patients with diabetes in India. Methods: Health care providers throughout India who treated patients with diabetes and hypertension were invited to participate in an online survey and periodic 21 virtual meetings. They were questioned about their perception and practices in managing these patients, and strategies to improve blood pressure (BP). Results: The online survey was completed by 2,513 health care providers, and 344 participated in virtual meetings. More than 50% reported that 31–50% of their patients with diabetes also had hypertension. Home BP monitoring was recommended by 88%, and lifestyle modifications were consistently recommended. Choice of antihypertensive treatment varied based on comorbidities, and a renin–angiotensin system blocker plus a calcium channel blocker (CCB) was the most common combination for dual antihypertensive therapy. Suggested strategies to improve BP control included patient awareness/education, lifestyle modifications, better follow-up/monitoring, and optimization of therapy. Conclusion: Indian health care providers were aware of clinical recommendations and practices regarding treatment of patients with diabetes and hypertension, and generally make clinical decisions consistent with current guidelines. Optimization of care for these patients is essential to reduce cardiovascular disease risk and improve patient outcomes.

Evaluation of clinical profile and screening guidelines of retinopathy of prematurity in an urban level III neonatal intensive care unit

Purpose: To evaluate the clinical profile and screening guidelines of retinopathy of prematurity (ROP) in an urban level III neonatal intensive care unit (NICU). Methods: Infants with ?2000?gm birth weight or <34 weeks gestational age were prospectively screened for ROP in an urban level III NICU between January 2018 and December 2020, based on national screening guidelines. Standard guidelines were used for ROP classification and treatment. Results: In total, 211 infants completed screening; 46 (21.8%) infants developed ROP and 13 (6.2%) had type 1 (laser treatable) ROP. Of the 46 infants with ROP, 44 (95.65%) had zone 2 and two (4.34%) had zone 1 disease. In the 102 infants with ?1500?gm birth weight, the incidence of ROP and type 1 ROP were 41.18% and 11.76%, respectively. Out of the 109 infants with >1500?gm birth weight, four (3.67%) developed ROP and one (0.91%) infant (an outborn) required treatment. Conclusion: The majority of infants developing ROP in a level III urban NICU had ?1500?gm birth weight. Zone 1 ROP was uncommon. Incidence of ROP in heavier infants (>1500?gm birth weight) was low, and treatment was required in a rare instance. In an urban NICU, the burden of ROP screening and treatments shifts to small and low?birth?weight infants
