Abstract

Abstract Background Cataract and glaucoma are the major causes of blindness in Nepal. Bhaktapur is one of the three districts of Kathmandu valley which represents a metropolitan city with a predominantly agrarian rural periphery. This study was undertaken to determine the prevalence of visual impairment, cataract surgery and awareness of cataract and glaucoma among subjects residing in this district of Nepal. Methods Subjects aged 40 years and above was selected using a cluster sampling methodology and a door to door enumeration was conducted for a population based cross sectional study. During the community field work, 11499 subjects underwent a structured interview regarding awareness (heard of) and knowledge (understanding of the disease) of cataract and glaucoma. At the base hospital 4003 out of 4800 (83.39%) subjects underwent a detailed ocular examination including log MAR visual acuity, refraction, applanation tonometry, cataract grading (LOCSΙΙ), retinal examination and SITA standard perimetry when indicated. Results The age-sex adjusted prevalence of blindness (best corrected Conclusion The low prevalence of visual impairment and the high cataract surgical coverage suggests that cataract intervention programs have been successful in Bhaktapur. Awareness and knowledge of cataract and glaucoma was very poor among this population. Eye care programs needs to be directed towards preventing visual impairment from refractive errors, screening for incurable chronic eye diseases and promoting health education in order to raise awareness on cataract and glaucoma among this population.

Abstract

To find out the outcome of laser photocoagulation in clinically significant macular edema (CSME) by optical coherence tomography (OCT) METHODS: It was a prospective, non-controlled, case series study enrolling 81 eyes of 64 patients with CSME between August 2008 and January 2010. All patients received modified grid photocoagulation with frequency doubled Nd: YAG laser. Each patient was evaluated in terms of best-corrected visual acuity (BCVA) and regression or progression of maculopathy after laser therapy at 1, 3 and 6 months. Spearman's correlation test was used to show the correlation between BCVA and total macular volume (TMV). Analysis of variance (ANOVA) was used to compare among groups and independent t-test was used to compare in each group.There is high correlation between BCVA and TMV (P≤0.001). BCVA improved in 50.6 %, remained static in 39.5% and deteriorated in 9.9% patients after 6 month of treatment. The Baseline TMV (mean and SD) were 9.26±1.83, 10.4±2.38), 11.5±3.05), 8.89±0.75 and 9.47±1.98mm(3) for different OCT patterns, ST (sponge like thickening), CMO (cystoid macular edema), SFD (subfoveal detachment), VMIA (Vitreo macular interface abnormality) and average TMV respectively (P=0.04). After 6 months of laser treatment, the mean TMV decreased from 9.47±1.98mm(3) to 8.77±1.31mm(3) (P=0.01). In ST there was significant decrease in TMV, P=0.01, Further within these groups at 6 months, they were significantly different, P=0.01.OCT showed the different morphological variant of CSME while the response of treatment is different. TMV decreased the most and hence showed the improvement in vision after 6 months of laser treatment. In the era of Anti vascular endothelial growth factors (VEGFs), efficacy of laser seems to be in shadow but it is still first line of treatment in developing nation like Nepal where antiVEGFs may not be easily available and affordable.

Abstract

Background: The purpose of this study was to evaluate the outcome of pterygium excision with inferior conjunctival autografting for primary pterygium. Methods: This was a prospective noncomparative interventional case series study enrolling 50 eyes of 50 patients with primary pterygium between November 1, 2010 and October 30, 2011. All patients underwent the standard surgical technique for pterygium excision with inferior conjunctival autografting. The sampling method was purposive. The study variables were complications of surgery and recurrence rates during a follow-up period of 6 months. Results: The mean age of the patients was 43 ± 7.97 (range 26-64) years. Grade 1 pterygium comprised 64% while grade 2 pterygium comprised 36% of cases. The mean size of pterygium was 3.2 ± 0.60 mm. Minor complications did occur, but only 4% required resuturing. Recurrence occurred in two eyes (4%) which we detected 3 months after surgery in both cases. We observed conjunctival scarring at the donor site in four eyes (8%); however, there was no symblepharon formation or restriction of upgaze. Conclusion: Inferior conjunctival autografting is an effective technique with a low recurrence rate. This is a useful technique when it is not possible or desirable to use the superior conjunctiva as a donor source. It is an especially good option for preserving the glaucoma filtration site for the future. [ABSTRACT FROM AUTHOR]

Abstract

Background: Multi-drug resistance (MDR) and extensive-drug resistance (XDR) associated with extended-spectrum beta-lactamases (ESBLs) and carbapenemases in Gram-negative bacteria are global public health concerns. Data on circulating antimicrobial resistance (AMR) genes in Gram-negative bacteria and their correlation with MDR and ESBL phenotypes from Nepal is scarce. Methods: A retrospective study was performed investigating the distribution of ESBL and carbapenemase genes and their potential association with ESBL and MDR phenotypes in E. coli, Klebsiella spp., Enterobacter spp. and Acinetobacter spp. isolated in a major tertiary hospital in Kathmandu, Nepal, between 2012 and 2018. Results: During this period, the hospital isolated 719 E. coli, 532 Klebsiella spp., 520 Enterobacter spp. and 382 Acinetobacter spp.; 1955/2153 (90.1%) of isolates were MDR and half (1080/2153) were ESBL producers. Upon PCR amplification, blaTEM (1281/1771; 72%), blaCTXM-1 (930/1771; 53%) and blaCTXM-8 (419/1771; 24%) were the most prevalent ESBL genes in the enteric bacilli. BlaOXA and blaOXA-51 were the most common blaOXA family genes in the enteric bacilli (918/1771; 25%) and Acinetobacter spp. (218/382; 57%) respectively. Sixteen percent (342/2153) of all isolates and 20% (357/1771) of enteric bacilli harboured blaNDM-1 and blaKPC carbapenemase genes respectively. Of enteric bacilli, Enterobacter spp. was the most frequently positive for blaKPC gene (201/337; 60%). The presence of each blaCTX-M and blaOXA were significantly associated with non-susceptibility to third generation cephalosporins (OR 14.7, p < 0.001 and OR 2.3, p < 0.05, respectively).The presence of each blaTEM, blaCTXM and blaOXA family genes were significantly associated with ESBL positivity (OR 2.96, p < 0.001; OR 14.2, p < 0.001 and OR 1.3, p < 0.05 respectively) and being MDR (OR 1.96, p < 0.001; OR 5.9, p < 0.001 and OR 2.3, p < 0.001 respectively). Conclusions: This study documents an alarming level of AMR with high prevalence of MDR ESBL- and carbapenemase-positive ESKAPE microorganisms in our clinical setting. These data suggest a scenario where the clinical management of infected patients is increasingly difficult and requires the use of last-resort antimicrobials, which in turn is likely to intensify the magnitude of global AMR crisis.
