Demographic and Clinical Characteristics of Patients Presenting With Angiotensin-converting Enzyme Inhibitors Induced Cough.

Introduction Angiotensin-converting enzyme inhibitors (ACEi) induced cough is still the greatest challenge in the continued utilization of ACEi for management of hypertension. The clinical pattern and related risk factors predisposing patients to ACEi-induced cough have not been studied in Pakistani hypertensive patients as yet. Hence, this study was conducted. Methods In this prospective, observational study individuals of both genders, of age 18 years or more, known cases of hypertension, taking ACEi, and having a chronic cough (>14 days) without any respiratory etiology were included. Their demographic and clinical characteristics were recorded. All data were managed using SPSS for Windows version 20.0 (IBM Corp., Armonk, NY). Results Enalapril was the most frequently prescribed ACEi (n=58; 47.2%) in patients with ACEi-induced cough followed by captopril (n=28; 22.7%), lisinopril (n=23; 18.7%), and ramipril (n=14; 11.4%). Higher body mass index (p=0.002), smoking (p=0.008), and longer time from the start of ACEi to the occurrence of cough (p=0.04) were the significant determinants of ACEi-induced cough. There were 33 (26.8%) participants who planned to request their physician to prescribe them an alternate medication due to their cough. Conclusions Enalapril was the most commonly ACEi prescribed among patients with ACEi-induced cough. Higher BMI, smoking, and longer time from the start of ACEi to the occurrence of cough related to ACEi-induced cough.

Comparison of the Efficacy of Duloxetine and Pregabalin in Pain Relief Associated with Diabetic Neuropathy.

Introduction Painful diabetic peripheral neuropathy (PDPN) complicates 25% of type II diabetes mellitus. It has a profound impact on diabetes-related morbidity and worsens the quality of life. Both pregabalin and duloxetine may be indicated for PDPN. In this study, the efficacy of duloxetine and pregabalin was compared in patients with PDPN. Methods It was a single-centre open-label study conducted with patients of diabetes mellitus type II diagnosed with PDPN. Patients were randomized to receive 60 mg/daily duloxetine or 300 mg/daily pregabalin. Pain scores were recorded using visual analogue scale (VAS) on day 0, week 4, and week 12. Data was entered and analysed using SPSS version 22.0 (IBM Corp., Armonk, NY). Results In the duloxetine group, the mean VAS score decreased from 6.81 ± 0.91 to 4.01 ± 1.12 with 12 weeks of therapy (p <0.0001). In the pregabalin group, the mean VAS score decreased from 6.99 ± 1.12 to 4.91 ± 0.82 with 12 weeks of therapy (p <0.0001). At 12 weeks, duloxetine showed lower VAS scores than pregabalin (p <0.0001). In the duloxetine group, the mean change in VAS score over time was - 2.80 and in the pregabalin group, the mean change was - 2.80. Adverse events were reported in 17.9% of the participants. Lethargy/somnolence (8.1%) and peripheral edema (3.4%) were commonly reported in the pregabalin group and constipation (6.9%) and orthostatic hypotension (4.6%) were commonly reported in the duloxetine group. Conclusions Duloxetine at a daily fixed dose of 60 mg is efficacious in the relief of neuropathic pain. Pregabalin also showed a comparable outcome. Both duloxetine and pregabalin have a promising safety profile and are well-tolerated.

Sensorineural Hearing Loss and Its Relationship with Duration of Chelation Among Major ß-Thalassemia Patients.

Introduction Thalassemia is a common genetic disorder worldwide, also occurring frequently in Karachi, Pakistan. Beta (ß)-thalassemia major patients need repeated transfusions which cause iron overload. Patients are treated with chelating agents to reduce the high serum ferritin level and to decrease morbidity and mortality due to increased iron levels. This combined therapy also leads to some complications. One of them is the sensorineural hearing loss (SNHL). To date, no data is available in Pakistan regarding SNHL among major ß-thalassemia patients on chelating therapy.  Methods A cross-sectional study was performed in collaboration with the Thalassemia Center and Dr. Ruth Pfau at the Department of Ear, Nose, and Throat, Civil Hospital, Karachi, Pakistan. The variable to detect hearing was pure tone air and bone conduction thresholds at the frequencies of 250 - 4,000 Hz. Clinical data, such as chelating agent dose, duration, and hearing status, were recorded. Demographic characteristics, like age, gender, height, and weight, were noted. The hemoglobin and serum ferritin levels of the subjects were also included. Results Forty-five percent of cases of thalassemia were suffering from SNHL. In the right ear, the Pearson correlation of chelating agent dose (mg) with SNHL was mildly positive and statistically significant (r = 0.261, p < 0.001), (r = 0.337, p < 0.001), (r = 0.198, p = 0.005), and (r = 0.207, p = 0.003) at the frequencies of 250, 500, 1,000, and 2,000 Hz, respectively, and the Pearson correlation of chelating agent used (in months) with SNHL was mildly positive and statistically significant (r = 0.232, p = 0.001), and (r = 0.301, p < 0.001) at frequencies 250 to 500 Hz, respectively. In the left ear, the Pearson correlation of chelating agent dose (mg) with SNHL was mildly positive and statistically significant, (r = 0.191, p = 0.007), (r = 0.202, p = 0.004), (r = 0.297, p < 0.001), (r = 0.183, p = 0.010) and (r = 0.221, p = 0.002) at frequencies 250, 500, 1,000, 2,000, and 4,000 Hz, respectively, and Pearson correlation of chelating agent used (months) with SNHL was mildly positive and statistically significant only at the frequency of 2,000 Hz (r = 140, p = 0.049).  Conclusion Chelation therapy and regular blood transfusions, apart from prolonging the life of thalassemic patients, also leads to some complications. With this survey, it was concluded that almost half of the patients had normal hearing, while the other half had sensorineural hearing loss after the use of deferasirox. It is inferred that the incidence of SNHL is not only dose-related but the duration of use of a chelating agent is also a contributing factor.

Role of Montelukast in Improving Quality of Life in Patients with Persistent Asthma.

Introduction Maintenance therapy of asthma has a crucial role in keeping the disease dormant and preventing frequent acute exacerbations. Asthma control may be achieved by inhaled corticosteroids (ICS) and/or long-acting beta-agonists (LABA). Leukotriene receptor antagonist - montelukast - may be added as an add-on to ICS/LABA or may also be given in monotherapy. The aim of this study was to evaluate the role of montelukast monotherapy as asthma control and its impact on the quality of life of these patients. Methods In this prospective, open-label, interventional study, montelukast 10 mg once daily was given to patients with mild to moderate persistent asthma for four weeks. Quality of life (QOL) was assessed on the Asthma Quality of Life Questionnaire - Standard (AQLQ-S) questionnaire. Asthma control was assessed on the Asthma Control Test (ACT). Data was entered and analyzed using SPSS version 23.0. Results On AQLQ-S, overall QOL improved with one month of montelukast therapy significantly. On sub-scales, except for emotional function, all other three sub-scales including symptoms, activity limitation, and environmental function improved significantly. Asthma control score also significantly improved with one month of montelukast therapy. Conclusion Montelukast has an effective role in asthma control and improvement of QOL in patients with mild to moderate persistent asthma.

Risk Factors Associated with Surgical Site Infections: A Retrospective Report from a Developing Country.

Introduction Any infection occurring at the site of a surgical incision superficially or deep within the fascia, within 30 days of a surgical procedure is termed as a surgical site infection (SSI). Due to limited resources, non-adherence to infection control guidelines and substandard sterilization practices, the incidence is higher in developing countries. The aim of this study is to estimate the incidence of surgical site infections in general surgeries at a tertiary care hospital in Pakistan and identify the predisposing risk factors. Methods This was a retrospective analysis that included all surgical records from June 1, 2018, to December 31, 2018. After exclusion, 882 records were included. The incidence of SSI and predisposing risk factors were noted. Data were entered and analyzed using SPSS v. 22.0 (IBM Corp, Armonk, NY, US). Results The incidence of SSI was 8.84% (n=78). SSIs were more common in older participants (11.4% vs. 6.4%; p=0.009), in patients with more than 24 hour of preoperative hospital stay (11.2% vs. 64%; p=0.013), in procedures of longer duration (1.53 ± 0.35 vs 2.57 ± 0.17; p<0.0001), and in emergency surgeries (19.2% vs. 7.5%; p=0.0001). The combined incidence of SSIs in American Society of Anesthesiologists (ASA) index III and above was 37 (47.4%) and that in I and II was 41 (52.6%) (p<0.00001). Conclusion This study has revealed a very high incidence of surgical site infections. These infections are more common in elderly patients, patients undergoing emergency surgeries, those with longer preoperative hospital stay and longer surgical duration, and patients with a high ASA index.

Frequency of Medication Non-compliance in Hypertensive Patients Presenting with Stroke: A Case-control Study.

Introduction Medication compliance (MC) is essential for optimum control and delaying disease progression and complications in chronic illnesses. Patients with hypertension have been repeatedly studied for their pattern of MC in the literature. However, whether or not lack of MC is an issue grave enough to cause medical complications of hypertension is still not clear. The aim of this study was to evaluate if the lack of MC is related to hypertension-related stroke. Methods In this case-control, observational study, 100 hypertensive patients admitted with hypertensive stroke were included. These cases were compared with 200 hypertensive patients without any major hypertensive complication recruited from outpatient clinics. Medication compliance was calculated using the Morisky Medication Adherence Scale (MMAS). Data was entered and analysed using SPSS v. 22.0. Results High compliance patients were more in the control group than the cases (34.5% vs. 27%), similar was with medium (41.5% vs. 30%). and low compliance patients (43% vs. 24%; p = 0.003). In both high compliant and moderate-to-low compliant group, mean systolic and diastolic blood pressure was higher among the cases (p <0.05). Among high compliant patients, cases were taking more pills per day than the controls (p = 0.032). Among moderate-to-low compliant patients, 80% perceived themselves to be highly compliant and only 20% perceived to be low complaint in the cases, as compared to 60% controls perceiving themselves compliant and 40% as low complaint (p = 0.001). Conclusion The incidence of low medication adherence is significantly higher in patients with major hypertensive complications such as stroke as compared to hypertensive patients without any major complication.

Clinical Spectrum of Near-miss Cases in Obstetrics.

Introduction Near-miss obstetric cases are the ones which have survived childbirth after a life-threatening and complicated pregnancy. The aim of this study is to evaluate important characteristics and causes of near-miss cases, compare them with maternal deaths, and assess urgent interventions managing these patients. Materials and methods This prospective, cross-sectional study was conducted in the intensive care unit of the Obstetrics and Gynecology department. Clinical spectrum of near-miss patients was compared with that of maternal deaths. Data was entered and analyzed using Statistical Package for the Social Sciences (SPSS) Statistics for Windows, version 21.0 (IBM Corp., Armonk, NY). Results The incidence of near-miss events was 31.4/1,000 live births. The incidence of maternal mortality was 8.2/1,000 live births. The ratio of near-miss to maternal mortality was 3.8:1. Hemorrhage, hypertensive disorders, and puerperal sepsis were the leading causes of near-miss cases. Conclusion Evaluation of characteristics of near-miss cases helps in establishing severe maternal morbidity. These high-risk patients must be provided urgent interventions to prevent maternal mortality.

Barriers Experienced by Medical Students in Conducting Research at Undergraduate Level.

Introduction Undergraduate medical research is very important not only for scientific learning but also for career progress. However, there are barriers, especially in developing countries, that restrict undergraduate research. This study aims to evaluate the barriers experienced by medical students in conducting research at undergraduate level. Methods It was an observational, cross-sectional survey conducted with 687 clinical students of two public medical universities of Pakistan. A self-structured questionnaire consisting of seven items was administered to assess the barriers in conducting research at undergraduate level. Data was processed and analysed through SPSS v 22.0 (IBM Corp., Armonk, NY, USA). Results Lack of knowledge as a barrier was identified by 90.68% (n = 623) students. The second most common barrier identified by the students was lack of time (88.79%; n = 610), followed by lack of mentoring as the third most common barrier (85.74%; n = 572). Sub-group analysis showed that lack of knowledge, lack of mentoring, limited data base access, lack of time, and lack of finances were more crucial barriers for female gender (p < 0.05). Only lack of interest was a crucial barrier for male gender (p < 0.05). Conclusion A number of barriers need to be addressed in order to enhance students' participation in clinical research such as lack of interest, funding, and poor availability of research mentors and access to scientific databases to improve participation in clinical research. Substantial amendments in the medical undergraduate curriculum are needed.

Knowledge and Attitude of General Pakistani Population Towards Antibiotic Resistance.

Introduction The emergence and continuous spread of drug resistant bacteria has become one of the leading health concerns globally. Persistent failure to develop and/or discover new antibiotics along with irrational use of existing antibiotics is associated with rise in antibiotic resistance. There is poor understanding of antibiotics usage and their preciousness among the masses which result in careless utilization and hence, the emerging antibiotic resistance. The aim of this study is to evaluate the knowledge and attitude of Pakistanis towards antimicrobial resistance (AMR). Methods This observational cross-sectional survey was designed in the form of an online pro forma circulated in January 2019. It was a self-structured pro forma which included age, gender, and 10 questions - five to assess the knowledge and five to assess the attitude towards AMR. Each question was to be responded with a "Yes" or a "No." For knowledge assessing questions "do not know" was also an option. Data was entered and analysed using SPSS version 22 (IBM Corp., Armonk, NY). Results Of 1,132 participants, 837 (73.9%) thought that it was alright to stop antibiotics course whenever they felt better, 505 (44.6%) thought that frequent and unnecessary use of antibiotics actually decrease their effectiveness, and 208 (18.4%) participants thought it was correct to take antibiotics for cold and influenza. There were 157 (13.9%) participants who had not followed the duration of treatment as given in their doctor's prescription, 49 (4.4%) who had changed their antibiotic dose without doctor consultation, 467 (41.3%) who had reused leftover antibiotics from their previous prescription, 700 (61.8%) who had suggested it to their doctors to prescribe them antibiotics and 378 (33.4%) participants who had purchased antibiotics without any prescription in the last one year. Conclusion Pakistani individuals are not as knowledgeable about antibiotic resistance as severe the issue is in this region. Their attitude towards utilization of antibiotics is not very promising. It becomes essential to initiate antibiotic stewardship programs and educate the masses regarding efficacious and safe use of antibiotics in this region.
