To assess the role of cataract extraction in glaucoma management by its intraocular pressure lowering effect.

OBJECTIVE: To measure the mean change of intraocular pressure in glaucoma patients with cataract after uncomplicated phacoemulsification surgery with intraocular lens implanted in capsular bag. METHODS: The quasi-experimental study was conducted at the Ophthalmology Department of Pakistan Institute of Medical Sciences Shaheed Zulfiqar Ali Bhutto Medical University, Islamabad, Pakistan, from June 11 to December 10, 2018, and comprised patients who had uncomplicated cataract extraction by phacoemulsification with intraocular lens implant in the capsular bag in glaucomatous eyes of age 30-80 years. Visual acuity, intraocular pressure, slit lamp examination, fundoscopy, visual fields, details about topical medication and relevant history were recorded not more than 5 days before cataract extraction. Intraocular pressure was recorded using Goldman's applanation tonometer one day before surgery, and post-surgery 1 month and 3 months. Data was analysed using SPSS 20. RESULTS: Of the 40 patients, 19(47.50%) were males and 21(52.50%) were females. The overall mean age was 52.23±9.44 years. Mean pre-operation intraocular pressure was 20.42±1.69mmHg, while at 1 month post-surgery it was 18.55±0.90mmHg and at 3 months it was 17.03±1.19mmHg (p=0.0001). CONCLUSIONS: There was a significant change in intraocular pressure readings in glaucoma patients with cataract after uncomplicated phacoemulsification surgery with intraocular lens implanted in capsular bag.

The association between ethnicity, environmental and lifestyle factors and chronic disease in the development of pseudoexfoliation syndrome.

OBJECTIVES: To determine the association between ethnicity, environmental factors, lifestyle factors, chronic diseases and pseudoexfoliation syndrome (PEX). METHODS: A case control study conducted at four major hospitals in Pakistan from January to November 2019, with 241 cases and 294 controls, aged ≥ 40 years, who were administered a questionnaire assessing demographics, lifestyle factors, chronic diseases and ethnicity. Multivariate binary logistic regression was applied to calculate the odds ratio between cases and controls. RESULTS: PEX was found to be positively associated with ethnicity (p<0.001), time spent outdoors (p<0.001), educational status (p<0.001), asthma (p<0.001), mean age (p<0.001), daily tea intake (p=0.003), weighted maximum temperature (p<0.001) and weighted mean temperature (p=0.004). Poor association was found with weighted latitude (p=0.526) and weighted minimum temperature (p=0.079). Odds ratios for patients with asthma (OR=7.366, regression coefficient=1.993, p<0.001) Pathan ethnicity (OR=1.616, regression coefficient=0.48, p=0.016) and mean weighted temperature (OR=0.907, regression coefficient-0.097, p=0 .000) were significant in diagnosed cases of PEX. CONCLUSION: Individuals with Pathan ethnicity and asthmatics should be made aware of the risk of developing PEX and the importance of periodic screening. Limiting exposure to sunlight and cold and reducing the intake of tea may help in reducing in the chances of developing PEX.

Assessment of red cell distribution width, glycaemic control and diabetes related complications - the ARDENT Study.

OBJECTIVE: To assess the association of red cell distribution width with glycaemic control and the presence of complications in diabetes patients. METHODS: The cross-sectional study was done at the Pakistan Institute of Medical Sciences, Islamabad, Pakistan, from September to November 2017, and comprised patients with type 2 diabetes. Clinical and demographical characteristics were documented and they were subjected to complete blood count, red cell distribution width, glycated haemoglobin, fasting and random blood glucose, lipid profile, urea and creatinine. The presence of complications were assessed during clinical examination. SPSS 20 was used for data analysis.. RESULTS: There were 349 patients with a mean age of 53.14±11.77 years. The mean duration of diabetes was 8.36±6.64 years and mean glycated haemoglobin was 9.05±1.93. Red cell distribution width was significantly associated with the duration of diabetes, hypertension, macrovascular and microvascular complications and extent of glycaemic control (p<0.0001 each). A statistically significant linear relationship was observed between red cell distribution width and the number of macrovascular and microvascular complications (p<0.0001) and glycated haemoglobin (p<0.0001). Mean red cell distribution width was 13.94±1.66, 14.72±1.38, and 15.76±1.55 for optimal control, borderline control and poor control respectively. This linear incremental pattern was statistic ally significant (p<0.0001). CONCLUSIONS: The linear association of red cell distribution width with glycated haemoglobin may enable its use as a measure of the extent of hyperglycaemia.

METHODS: The cross-sectional study was conducted at Pakistan Institute of Medical Sciences, Islamabad, Pakistan, from July to December 2017, and comprised patients of diabetes type 2. After noting down demographic and clinical parameters, diabetes distress of the subjects was measured by applying the 17-item diabetes distress scale which also assesses sub domains like emotional burden, physicianrelated distress, regimen-related distress and interpersonal distress. SPSS 20 was used to analyse data. RESULTS: There were 349 subjects with a mean age of 53.14±11.77 years, mean diabetes duration of 8.36±6.64 years and a mean glycated haemoglobin value of 9.05±1.93%. Mean overall diabetes distress score was 2.55±0.75, signifying moderate distress. Overall, prevalence of diabetes distress was found among 266(76.2%) subjects;164(47%) moderate and 102(29.2%) high level distress. Emotional burden was most substantially elevated, with 296(84.8%) patients reporting moderate to high levels. Total diabetes distress was significantly related to demographic background (p<0.0001), education level (p=0.015), monthly income, frequency of administration of medication, adherence to medical treatment (p<0.05), number of complications (p<0.05) and overall glycaemic control (p<0.001). CONCLUSIONS: Modifiable factors, such as frequency of medication and compliance to treatment, should be addressed with the aim of decreasing diabetes distress and improve glycaemic control..

Association of dyslipidaemia in patients with varying degrees of Vitamin D deficiency in the Asian population.

OBJECTIVE: To investigate the associations of dyslipidaemia with varying levels of 25 hydroxy vitamin D3 deficiency. METHODS: This cross-sectional study was conducted at the Pakistan Institute of Medical Sciences, Islamabad, Pakistan, from July 2016 to January 2017, and comprised patients having varying levels of 25 hydroxy vitamin D3 deficiency. Patients were stratified according to the severity of deficiency and had their serum fasting lipid profiles measured. SPSS 20 was used for data analysis. RESULTS: Of the 175 participants, 124(70.9%) were female and 51(29.1%) were male. The overall mean age of the patients was 47.7±12.2 years (range: 18-65 years). A very strong inverse correlation was found between vitamin D levels and low-density lipoprotein cholesterol (p<0.001) and a similar trend was obtained for vitamin D and total cholesterol (p<0.001). With regards to triglycerides, a modest inverse correlation was found (p=0.05). No significant association was documented between 25 hydroxy vitamin D3 levels and high-density lipoprotein cholesterol (p=0.3). CONCLUSIONS: An inversely proportional relationship was found between total cholesterol, low-density lipoprotein cholesterol and triglycerides against varying levels of vitamin D deficiency.

Evolving Spectrum of Dengue: A Two-Year Experience From a Tertiary Care Hospital in Pakistan.

OBJECTIVE: This study focused on examining the clinical manifestations, disease severity, and outcomes among cases of dengue fever (DF) confirmed through serological testing. The study specifically targeted individuals admitted to a tertiary care hospital in Islamabad, Pakistan. METHODOLOGY: This prospective observational study at the Pakistan Institute of Medical Sciences, Islamabad, Pakistan, tracked 1,003 patients from admission to discharge or death between August 2022 and November 2023. Patients were monitored, and admission criteria were established based on the identification of warning signs. The data collection process encompassed gathering demographic information, documenting clinical symptoms, and utilizing a severity classification system for the disease. Outcome measures comprised the duration of critical illness, length of hospital stay, overall outcomes (discharge or mortality), and the assessment of complications. The collected data were analyzed using IBM Statistical Package for the Social Sciences (SPSS) software version 22.0 (IBM Corp., Armonk, NY). RESULTS: Baseline characteristics revealed a male predominance (67.8%), with an average age of 35.77 years, and common comorbidities such as hypertension (9.3%) and diabetes mellitus (7.3%). Dengue fever was most prevalent among patients whose blood group was B+ (15.0%). Nonstructural protein 1 (NS1) was positive in 73.4% of the cases. Fever was the predominant complaint in 98.0% of instances. Common bleeding manifestations included epistaxis, gum bleeding, and hematemesis. About 52.20% of cases were observed to have severe thrombocytopenia at admission. Hospital-related aspects demonstrated a mean stay of 3.35 days, a critical phase lasting 1.68 days, and rare complications like expanded dengue syndrome (2.2%). Encouragingly, 98.9% of patients were discharged, 0.4% were shifted, and 0.7% succumbed to the disease. CONCLUSION: This study comprehensively analyzes the demographic and clinical aspects of DF, emphasizing a male predominance and the fact that fever was the most common presenting complaint. The duration of hospitalization revealed a brief mean stay, a short critical phase, and low complication rates, with a high discharge rate suggesting positive outcomes.
