RIPASA versus Alvarado score in the assessment of acute appendicitis: A prospective study.

Objectives: This study aimed to compare Raja Isteri Pengiran Anak Saleha Appendicitis (RIPASA) and Alvarado scoring to accurately identify acute appendicitis. Material and Methods: A cross-sectional prospective study was carried out in the department of surgery. Patients were enrolled and scored using RIPASA and Alvarado scoring systems. Appendectomy was done, and the specimen was sent for histopathology examination, which was used as the gold standard for diagnosis. Among 400 recruits, 11 patients were lost to follow-up, giving us a sample size of 389 patients. The cut-off value for RIPASA and Alvarado scores was 7.5 and 7.0, respectively. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy in diagnosing acute appendicitis of both scores were analyzed using SPSS. Results: Among 389 patients, 256 (66%) were males, and 277 (71%) were under the age of 40 years. RIPASA was more than 7.5 in 345 cases, while Alvarado was more than 7.0 in 261 patients. RIPASA score had a sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 95.8%, 87.9%, 98.9%, and 65.9%, respectively. In contrast, the ALVARADO score was 71.1% sensitive and 75.8% specific. RIPASA had a diagnostic accuracy of 95.12%, while Alvarado was only 71.46% accurate in diagnosing acute appendicitis. Conclusion: Compared to the Alvarado scoring system, RIPASA is a better tool in terms of accuracy, sensitivity, and specificity for diagnosing acute appendicitis.

Comparison Of Intraoperative Wound Irrigation With Aqueous Povidone-Iodine Solution To Normal Saline In Preventing Surgical Site Infections.

BACKGROUND: A surgical site infection (SSI) is a wound infection caused by pathogens, particularly bacteria, that occurs within 30 days of the surgery. Various methods have been employed to minimise infection rates of infection one of which is intra-operative wound irrigation. This study aims to compare the frequency of surgical site infections after wound irrigation of contaminated and dirty wounds with normal saline and aqueous povidone-iodine solutions. METHODS: This randomized controlled trial was carried out in the surgical department of Federal Government Polyclinic Hospital from January to December 2022. A total of 180 patients were randomly divided into two equal groups using blocked randomization. Group A had normal saline irrigation while Group B had aqueous povidone-iodine irrigation before surgical incision closure. Patients were followed till 30th post-operative day. Data was collected, entered and analyzed using SPSS 20.0. RESULTS: A total of 180 patients were recruited in this study, equally divided into Group A and Group B with 90 patients each. Fifty-three patients (58.9%) from group-A and 58 patients (64.4%) from group-B were having contaminated wounds and 37 patients (41.1%) and 32 patients (35.6%) had dirty wounds respectively. Surgical site infection was found in 29 patients (32.2%) of group-A and 26 patients (28.8%) of group-B (p=0.627). there was no significant difference between the two groups concerning surgical site infection. CONCLUSIONS: Irrigation of surgical wounds with aqueous povidone-iodine solution before primary closure was statistically similar to normal saline in preventing surgical site infections in contaminated and dirty wounds.

Haematological profile abnormalities; and its relationship with severity and outcome of COVID-19 infection.

Background: Corona virus disease (Covid-19) caused by corona virus (SARS Cov-2) has affected millions of people around the world. Many diagnostic modalities have been tested but the blood complete picture remains the initial and most easily accessible investigation in Covid-19. Objectives: The objective of this study was to find out the haematological abnormalities in relation to Covid-19 severity and outcome. Methods: This cross-sectional study was carried out from April 2020 to July 2020. One--hundred and fifty polymerase chain reaction (PCR) confirmed Covid-19 patients were inducted by random sampling. Haematological profile at admission was recorded. Data thus obtained was analyzed with respect to Covid-19 severity and outcome. The data was entered and analyzed using Statistical Package for Social Sciences (SPSS) version 19. Results: Out of a total of 150 patients included in the study, 77(51.3%) patients had mild disease at the time of admission, 42 (28%) had moderate disease while 31 (20.7%) had critical disease at the time of admission. Medians (interquartile range) of total leucocyte count (TLC), neutrophils, lymphocytes, neutrophils to lymphocytes ratio (NLR), platelets to lymphocytes ratio (PLR), neutrophils to monocyte ratio (NMR), monocyte to lymphocyte ratio (MLR) were 8.11 (IQR=4.88), 5.95 (IQR=4.58), 1.66 (IQR=1.10), 3.48 (IQR=4.20), 146.24 (IQR=130.75), 18.87 (IQR=14.07), 0.16 (IQR=0.13). Median NLR was higher in patients with critical illness 11.23 (IQR=10.70) as compared to those with stable 2.51 (IQR=1.77) and moderate 3.22 (IQR=3.60) disease (p< 0.000). Similarly TLC (p< 0.000), neutrophils (p< 0.000), lymphocytes (p< 0.000), NLR (p< 0.000), PLR (p< 0.000, p=0.001), MLR (p< 0.000), NMR (p< 0.000) had significant relationship with the severity and outcome of Covid-19 infection. Conclusion: Many haematological parameters are significantly different and can be used to predict the severity and outcome of Covid-19 infection.

Correlation of biochemical profile at admission with severity and outcome of COVID-19.

BACKGROUND: COVID-19 was detected in China in December 2019. The rapid dissemination and novelty of the disease resulted in an epidemic. This study aimed to identify biochemical parameters at admission that can be used to categorize severity and outcome of COVID -19 infection. MATERIALS AND METHODS: This cross-sectional study was conducted at Allied Hospitals of RMU from April 2020 to July 2020. It included 128 randomly selected confirmed COVID-19 patients. At admission, biochemical profile (total bilirubin, alanine aminotransferases {ALT}, aspartate aminotransferases {AST}, urea, creatinine, uric acid, sodium, potassium, and chloride were correlated with severity and outcome of COVID-19 by employing t-tests and ANOVA where required. Cut-off values to predict disease severity and outcome were calculated using ROC curve. RESULTS: The study comprised 46.1% non-severe, 29.7% severe, and 24.2% critical COVID-19 patients. 84.4% patients improved and 15.6% expired. Urea was increased in critical disease patients (p < 0.000). Higher ALT (p 0.030) and AST (p 0.004) levels were noted in severe and critical disease. Sodium (p 0.001) and chloride (p 0.026) were decreased in critical disease. Patients who expired had increased urea (p 0.000), ALT (p 0.040) and AST (p 0.002). At admission, urea >42.7 mg (sensitivity of 64.7%, specificity of 87.5%), AST >43.5 IU/L (64% sensitivity, 60% specificity), and sodium <136.9 mmol/L (sensitivity of 70.6%, specificity of 71.2%) predicted critical COVID-19 infection. CONCLUSION: At admission, increased urea, AST, and ALT along with decreased sodium can help in identifying COVID-19 patients with severe illness and poor outcome.

RESULTS: Of the total 212 patients, 36(16.9%) had some complication. There were significantly more complications in people aged 40 years or above compared to those <40 years (p<0.05). Of the total surgeries, 126(59.43%) were in the abdomino-pelvic region. CONCLUSIONS: Peri-operative complications were found to be significantly related with age of the patient and the type of surgery.

Assessment of Knowledge, Attitude, and Practices Regarding Self-medication for Acne Among Medical Students.

Introduction Acne is one of the most common skin conditions worldwide. Self-medication for acne is a fairly common practice among medical students. The objective of our study was to identify the prevalence of self-medication and to assess its knowledge, attitude, and practices among medical students. Materials and methods This descriptive cross-sectional study was conducted at Rawalpindi Medical University, Rawalpindi, Pakistan, from January 2019 to June 2019. Data were collected by using the convenient sampling technique. Students were asked to fill a semi-structured questionnaire. Students of all the medical years studying in our university were included in the study. Data were entered and analyzed using the Statistical Package for Social Sciences (SPSS) version 23.0 (IBM Corp., Armonk, US). Results Out of 349 students, 244 (69.9%) suffered from acne and self-medication was practiced by 123 (50.4%) acne sufferers. The practice of self-medication was significantly higher in students having acne lesions on the face (52.2%). The most common source of information was reported to be acquaintances (55.8%). Most of the students had knowledge of the dosage of drugs (46.3%) and precautions for their use (41.5%). Sixty-three percent of the students were of the opinion that self-medication is part of self-care. Most of the students read the expiration date on the drug label (88.6%). Conclusion Acne is a highly prevalent condition among medical students and the practice of self-medication among acne sufferers is high. The practice of self-medication and visits to dermatologists were both significantly more common in the students with lesions on the face. The knowledge of students regarding self-medication of acne was not adequate.

Preoperative and Operative Risk Factors for Conversion of Laparoscopic Cholecystectomy to Open Cholecystectomy in Pakistan.

Introduction The currently available literature suggests a wide range of conversion (4.9-20%) from laparoscopic cholecystectomy (LC) to open cholecystectomy (OC) despite the increase in surgical expertise. Open cholecystectomy is important as the last resort for safe surgical practice in complicated cases. Increased number of pre-operative and perioperative risk factors need to be identified to pre-empt conversion. However, there has been a significant decrease in conversion rates over the past few decades. This study was conducted to determine conversion rates in our population and to identify any significant risks for conversion. Methods This prospective study was conducted at the Shifa International Hospital, Islamabad, Pakistan, including 1081 cholecystectomies, performed over a two-year period from January 2017 to January 2019. Comparison of risk factors between the two groups; laparoscopic cholecystectomy (LC) group and conversion to open cholecystectomy (OC) group was done. Statistical analysis was done using SPSS 24.0.1. P<0.05 were considered significant. Results In our study, the overall conversion rate was 7.78%. Factors of conversion to open cholecystectomy (OC) included age ≥65, morbid obesity, diabetes mellitus, and previous abdominal surgery. Deranged alkaline phosphatase (ALP), increased total bilirubin, increased common bile duct (CBD) diameter, and multiple stones in ultrasonography showed a statistically significant association with the conversion. Per-operative findings of increased adhesions >50%, empyema gallbladder (GB), perforated GB, and scleroatrophic GB showed a higher risk of conversion too (p <0.05). However, there was no statistical association with preoperative endoscopic retrograde cholangiopancreatography (ERCP) to OC in our population. Conclusion An open cholecystectomy is a safe approach for patients with complicated gallbladder disease. No doubt laparoscopic cholecystectomy is the gold standard having its outstanding benefits. This study identifies predictors of choice for OC in addition to the decision to convert to OC. In view of the raised morbidity and mortality associated with open cholecystectomy, distinguishing these predictors will serve to decrease the rate of OC and to address these factors preoperatively.

Assessment of Knowledge of Symptoms of Ischemic Heart Disease in Population Visiting a Tertiary Care Hospital in Pakistan.

Introduction Cardiovascular diseases are an important cause of mortality in Pakistan. Developing nations like Pakistan with poor literacy rates and the majority of the population living in rural areas seem to be insufficient in their knowledge of symptoms. A study indicated that about half of the cardiac deaths occur within one hour of onset of symptoms, thus it is necessary to have adequate knowledge of symptoms to identify the sufferer and to pursue medical services as early as possible. The aim of our study was to assess the knowledge of ischemic heart disease (IHD) symptoms in the population and to investigate the relationship of age, gender, socio-economic status, education, and occupation with knowledge. Materials and Methods This was a descriptive cross-sectional study carried out in the Holy Family Hospital, Rawalpindi, Pakistan over a period of four months from May 2018 to August 2018. The study population comprised of people visiting the hospital. Individuals aged 18 and above were included while medical professionals were excluded. An interviewer-assisted semi-structured questionnaire was used as the data collection tool. After taking consent, 225 participants were asked about their demographic profile and to enlist as many symptoms of IHD as possible. Reference was made to the seven typical symptoms of IHD as recognized by the World Health Organization (WHO). Statistical Package for Social Sciences (SPSS), v23.0 (IBM SPSS Statistics, Armonk, NY) was used for the analysis. Independent samples t-test and one-way ANOVA test were applied; p ≤ 0.05 was considered significant.  Results Out of the seven symptoms endorsed by WHO, chest pain was most frequently identified (42%), followed by pain in the arm (23%), diaphoresis (19%), weakness and fainting (16%), dyspnea (15%), paleness (8%), and sickness and vomiting (5%). Mean score, out of seven symptoms, was 1.28 ± 1.19. Among the total participants, 34% could not enlist any symptom. Participants with higher education, skilled workers, and those having relatives who suffered from IHD showed significantly higher knowledge about IHD symptoms. Conclusions The study showed a paucity of knowledge about IHD symptoms among the participants. Hence it provides grounds for future awareness campaigns to educate the masses.

Comparison of Open Appendectomy and Laparoscopic Appendectomy in Perforated Appendicitis.

Introduction Laparoscopic appendectomy for nonperforated appendicitis is associated with improved outcomes. This study compares laparoscopic appendectomy and open appendectomy in cases of a perforated appendix by assessing surgical site infection, mean operating time, and length of hospital stay. Materials and methods This study was a prospective randomized study conducted at the Department of Surgery, Holy Family Hospital, Rawalpindi, Pakistan, from January 2016 to January 2017, by randomly allotting the laparoscopic or the open appendectomy technique to 130 patients by the lottery method. Patients having a perforated appendix were included after they provided informed consent. Data were entered and analyzed using IBM SPSS Statistics for Windows, Version 20.0 (IBM Corp., Armonk, NY, US). Results The frequency of wound site infection was significantly higher in open appendectomy (27.69%) than in the laparoscopic approach (10.77%; p=0.01). Mean hospital stay was slightly longer in the laparoscopic approach (4.38 ± 1.09 days) than in open appendectomy (4.18 ± 0.77 days; p=0.23). Mean operating time for laparoscopic appendectomy and open appendectomy was 46.98 ± 2.99 minutes and 53.02 ± 2.88 minutes, respectively (p<0.000). Conclusion Laparoscopic appendectomy was associated with fewer surgical site infections and shorter mean operating time than an open appendectomy.

Bacteriological Profile and Antibiogram of Cultures Isolated from Tracheal Secretions.

Background Respiratory infections are associated with high morbidity and mortality, especially in critically ill patients. The excessive use of broad-spectrum antibiotics has led to the development of drug resistance, thus resulting in the emergence of pathogens which are difficult to treat. The aim of this study was to identify common pathogens in tracheal secretions and to study the patterns of their sensitivity and resistance to various antibiotics. Materials and methods This descriptive cross-sectional study was conducted in the Department of Pathology and Microbiology, Holy Family Hospital, Rawalpindi, Pakistan, from August 2017 to December 2017, using the convenient sampling technique. Tracheal secretions from patients in the intensive care unit (ICU), tested in the Pathology and Microbiology Department of Holy Family Hospital, were included in the study. The culture was done on blood and MacConkey agar and the sensitivity pattern was performed on Muller Hinton agar. Data were analyzed using SPSS v.23.0. Results Out of the bacteria isolated from positive growth cultures, Acinetobacter (45; 53.6%) was the most common isolate followed by Klebsiella (11; 13.1%). Acinetobacter was most sensitive to tigecycline (94.7%), and gram-negative bacteria such as Acinetobacter, Klebsiella, and Pseudomonas showed resistance to higher generation cephalosporins. Conclusion Acinetobacter was the most common gram-negative bacilli isolated. Tigecycline was found to be effective against Acinetobacter.

Epidemiology, Bacteriological Profile, and Antibiotic Sensitivity Pattern of Burn Wounds in the Burn Unit of a Tertiary Care Hospital.

INTRODUCTION:  Burn wounds are commonly infected by organisms which delay wound healing. Therefore, it is necessary to evaluate the flora obtained from wounds of burn patients in order to determine the most effective treatment. The aim of this study was to determine the frequencies of various bacteria isolated from burn wounds and to determine their antimicrobial susceptibility.  Materials and methods: This descriptive cross-sectional study was conducted from January 2018 to November 2018 which included consecutive samples of burn wounds from patients admitted to the burn ward of a tertiary care hospital. Bacteria and their antimicrobial susceptibility were determined by swab cultures and sensitivity tests by standard aseptic techniques. Data were analysed via the Statistical Package for Social Sciences (SPSS), v23.0 (IBM SPSS Statistics, Armonk, NY). Chi-square tests were applied between qualitative variables, while the Kruskal-Wallis test was applied to compare the means of asymmetrical data. Bacterial isolates and their susceptibility pattern were represented as frequencies and pie charts. RESULTS:  A total of 178 samples were obtained from 109 patients from burn wounds. One hundred and twenty-two wounds (68.5%) showed growth and 56 (31.4%) showed no growth after 24 hours of incubation. Positive cultures were significantly more frequent in wounds of greater than one-week duration (p < 0.002). Out of 158 bacterial isolates, the most common isolate was Pseudomonas aeruginosa - 41 specimens (24.91%), followed by Staphylococcus aureus - 38 specimens (24.05%), Acinetobacter - 27 (17.09%), Klebsiella - 24 (15.19%), Escherichia coli - 13 (8.23%), Proteus - 7 (4.43%), other coliforms - 6 (3.8%), Enterococcus - 1 (0.63%), and Enterobacter - 1 (0.63%). Drug resistance to penicillin G, ampicillin, Augmentin, ceftazidime, cefotaxime, ceftriaxone, meropenem, and piperacillin+tazobactam was exceptionally high. CONCLUSION:  The most common bacterial isolates are Pseudomonas aeruginosa and Staphylococcus aureus. Piperacillin+tazobactam against Pseudomonas aeruginosa and vancomycin and linezolid against Staphylococcus aureus are highly effective and can be used as empirical therapies.
