Efficacy of Platelet Rich Fibrin in Myringoplasty.

OBJECTIVE: To determine the efficacy of usage of topical autologous platelet rich fibrin (PRF) in improving outcomes of myringoplasty regarding graft uptake and hearing improvement. METHODS: This study was conducted in the ENT department of Holy Family Hospital, Rawalpindi, over a period of six months from August 2019 to January 2020. It was designed as a prospective single blinded randomized controlled trial. The study involved a total of 50 participants in whom myringoplasty was done through post auricular approach using underlay technique. In 25 patients topical drops of PRF were used. Outcomes were compared after three months with the control group (n=25), who underwent myringoplasty without PRF. RESULTS: After three months follow-up, graft uptake was reported 78% and 52% in cases and controls, respectively (P=0.070). Mean hearing improvement was 18 dB and 6 dB in cases and controls, respectively (P=0.014). Postoperative infection occurred in 8% of the cases, and in 32% controls (P=0.037). CONCLUSION: Topical use of Platelet-Rich Fibrin during myringoplasty results in improved graft uptake. Hence, resulting in much improved hearing, significant reduction in infection rates and decrease in perforation sizes.

Frequency of otitis media with effusion among children aged 1-5 years presenting to immunization center of tertiary care hospitals, Rawalpindi.

Objective: We conducted this study to assess the etiopathogenic relation of otitis media with effusion (OME) in a group of children aged 1-5 years among the local population of Rawalpindi. Methods: This was a cross-sectional retrospective study. Study was conducted among the children presenting to the immunization center of three tertiary care hospitals of Rawalpindi. Otitis media was assessed by clinical examination and tympanometry from August 2019 to January 2020. Multi-factor regression analysis was then applied to recognize the statistical significance and association of various risk factors to OME. Results: Out of 400 children enrolled in this study, 108 (27.0%) had OME, out of which 65 (60.2%) were males and 30 (27.8%) were of age group 2-3 years. Multivariable regression analysis of risk factors associated with OME showed it was strongly associated with snoring (P < 0.001), last year symptoms (attack of ear aches with hearing loss [P = 0.002]), drugs (URTI antibiotics [P = 0.026], All 3 drugs [P = 0.013]). Conclusions: We found out that OME is a common disease which if not identified or treated timely can lead to other hard to cure health problems. Control of its etiopathogenic factors can play a major role in its prevention.

Diagnostic Accuracy of Right Bronchial Infiltration on Chest X-rays in Diagnosing COVID-19 Patients in the Early Stage of the Disease.

Purpose SARS-CoV-2 has been a diagnostic challenge for healthcare setups worldwide since 2019 due to its proximity to a myriad of pathological processes. Although reverse transcription - polymerase chain reaction (RT-PCR) and high-resolution computed tomography (HRCT) have helped in the diagnosis of the disease, they are not as widely available as chest X-rays. This study aims to investigate the diagnostic accuracy of right bronchial infiltration in chest X-ray in diagnosing COVID-19. Material and methods This was a validation study conducted in a single center in Riyadh, Saudi Arabia. A total of 114 patients were enrolled according to the selection criteria of the study. Consent was waived off on the condition of confidentiality maintenance as per the ethical review board. X-rays of suspected patients were viewed and analyzed by two blinded consultant radiologists. Patients were followed for their RT-PCR reports. Data were entered and analyzed in SPSS Statistics v.23.0 (IBM Corp., Armonk, USA). Results Among the 114 patients, the mean age was 46.2±17.3 years and 85 (74.6%) were males. The total number of COVID-19-positive patients were 82 (71.9%) while the patients presenting with right bronchial infiltration (RBI) were 94 (82.5%). RBI was significantly associated with the presence and absence of COVID-19 on PCR (p<0.001) and the presence of comorbidities (p<0.001). The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the sign were 84.04%, 85.00%, 96.34%, 53.12%, and 84.21%, respectively. Conclusions RBI can be used as a diagnostic sign in X-rays for early identification of COVID-19 positive patients. This feature can be used in the triage of patients. This would decrease the spread of disease by providing early time to intervene to isolate patients.

Prevalence and Biochemical Associations of Fever in Adults With Reverse Transcription Polymerase Chain Reaction Proven Coronavirus Disease Presenting at Tertiary Care Hospitals in Rawalpindi.

Background Clinically most apparent symptoms of COVID-19 include fever and cough, which in some patients show a worsening trend but are completely non-apparent in patients who present with an asymptomatic course of the disease. The aim of this study was to identify clinical and biochemical differences among polymerase chain reaction (PCR) positive patients who are either febrile or afebrile. Methods This study was conducted in Rawalpindi Medical University and Allied Hospitals between September and December 2020. All patients who tested positive for reverse transcription polymerase chain reaction (RT-PCR) COVID-19 were included in the study. After evaluation of 146 patients, 100 were selected, and with a response rate of 97%, a total of 97 patients were included in the final analysis. Depending on the presence of fever, the participants were divided into two groups. Both groups were then compared for baselines vitals and laboratory investigations. Data was entered and analyzed in SPSS v23.0 (IBM Inc., Armonk, New York). Results Among the 97 patients, 66 (68%) of the participants were male, and 31 (32%) were females. The mean age of the study participants was 45.23±18.08 years. Fever was present in 39 (40.2%) of the participants. When compared with patients with no fever, the patients with fever had greater severity of disease (p<0.001), higher heart rate (p<0.001), decreased oxygen saturation (p<0.001). Among the laboratory investigations, the fever group had a greater tendency of having deranged alanine aminotransferase (ALT) (70.82±29.23 vs. 32.83±16.22, p=0.010), Lymphocytes (1.56±0.54 vs. 2.12±0.94, p=0.003) and serum total bilirubin (1.06±0.36 vs. 0.55±0.21, p=0.009). Based on multiple regression analysis, the presence of fever is a predictor of derangement in ALT (OR=1.034, CI=1.001-1.068 p=0.025) and total bilirubin (OR=4.38, CI=2.14-6.78, p=0.021). Conclusion Fever may not be present among all patients presenting with COVID-19 infection, but those who have a fever have a greater risk of having deranged liver function tests. Hence, it is important to monitor liver function tests (LFTs) in COVID-19 patients presenting with fever.

Frequency of transfusion transmissible infections among blood donors of Rawalpindi District, Pakistan.

Background: Transmissible Infections (TTI's) are a cause of significant burden on health care facilities by imposing a threat of infection transmission through disease reservoirs in asymptomatic donors. This eventually leads to a serious challenge in acquiring blood bags in a country like Pakistan where transfusion dependent disease are of high prevalence. The objective of this study is to determine the seroprevalence of TTI's in blood donors in Rawalpindi District through a multi-center approach. Materials and Methods: This is an observational descriptive retrospective study based on 6 transfusion centers in the Rawalpindi District. The time frame of the study was from January 2015 to December 2018. A total of 223,242 donors were consecutively included and data on donor type, the purpose of transfusion, and seroprevalence (HBV, HCV, HIV, Syphilis, and Malaria) were collected through a structured questionnaire and laboratory investigation results. The collected data were entered in SPSS version 21.0 for analysis. Results: The seroprevalence of blood borne infections was 7,897 (3.537%) of which HBV, HCV, HIV, Syphilis and Malaria accounted for 2410 (1.080%), 3105(1.391%), 0(0.000%), 2017 (0.933%) and 365 (0.171%), respectively. Reactive samples reduced from 4.850% to 3.537% over 4 years, while there was a rise of 37.478% of blood donors from 2015 to 2018. The total number of voluntary donors and replacement donors was 22079 (9.890%) and 201156 (90.107%), with a rising incidence in voluntary donors from 2015 to 2018. A considerable number of donor bags were transfused to Thalassemia, Anemia, Leukemia and Hemophilia patients, 28156 (12.612%). This number also showed increasing rates from 11.654% to 14.017%. Conclusion: In conclusion, our study suggests that the risk of transmission through transfusion is still considerable. Targeting donors with a low-risk profile, a screening questionnaire, an ample supply of quality screening tests, and awareness campaigns for the diseases in question must be carried to further decrease the risk of transmission of TTIs in Pakistan.

Comparison of Ultrasonic Dissection and Suture Ligation for Mesoappendix in Laparoscopic Appendectomy.

Objective To compare the use of ultrasonic dissector and suture ligation for mesoappendix in laparoscopic appendectomy in terms of mean operative time and per-operative bleed. Methodology This was a randomized controlled trial conducted at Surgical Unit II, Holy Family Hospital over a period of six months. All patients with the diagnosis of acute appendicitis who presented in the emergency department of Holy Family Hospital on the call days of Surgical Unit II undergoing laparoscopic appendectomy were included in the study. After taking informed consent about the respective procedure, patients were allocated to two groups using computer-generated random numbers. Group A was operated using harmonic scalpel and in Group B suture ligation was done. Total time required to ligate the mesoappendix or to cauterize it using the harmonic scalpel was measured in minutes. Data was entered and analyzed in SPSS version 21.0 (IBM Corp., Armonk, NY). Results A total of 110 patients were enrolled in the study according to the inclusion criteria of the study. Patients were randomly divided into two equal groups. Patients in Group A were operated using harmonic scalpel whereas patients in Group B were operated by suture ligation for dealing the mesoappendix in laparoscopic appendectomy. Mean operative time to ligate the mesoappendix for Group A patients was 1.56 (SD = 0.68) minutes while that of Group B was 21.07 (SD = 2.84) minutes. There was no per-operative bleeding in case of Group A while its incidence was 24% of patients in Group B. Results were statistically significant. Conclusion The conclusion of the study is that the use of harmonic scalpel was better than suture ligation for ligating the mesoappendix in laparoscopic appendectomy in terms of mean operative time and per operative bleed, hence it's preferable over the later in laparoscopic appendectomy.

Diagnostic Value of High-Resolution Computed Tomography Scan in COVID-19: Do We Need to Think Outside the Box?

Background and objective The ambiguous nature and high infectivity of the coronavirus disease 2019 (COVID-19) have caused soaring morbidity and mortality worldwide. Real-time polymerase chain reaction (RT-PCR) is preferred for detecting COVID-19. However, its poor sensitivity and the emerging use of high-resolution CT (HRCT) scan for disease severity make the use of RT-PCR quite obsolete. In light of this, our study aimed to explore the beneficial role of HRCT and compare the HRCT findings across various patient demographics and parameters. Methods This cross-sectional study included 100 patients with clinical suspicion of COVID-19. All patients underwent a chest HRCT scan preceded by RT-PCR testing. We used the CT severity score (CTSS) of the chest to calculate disease severity. Demographical data and results of radiological findings were tabulated and compared across RT-PCR positivity, age, and gender. Independent samples t-test and chi-square test were used to analyze the data. Results Glass ground opacity was the most prevalent finding in 99% of the patients, followed by lymph node involvement, consolidation, and crazy-paving pattern. Pleural effusion was observed in only 10% of the patients while pericardial effusion and hiatal hernia were present in 5%. In RT-PCR-positive patients, the posterior basal segment of the lower lobe of the right and left lungs were found to be dominantly involved; however, the upper and middle lobes of the right lung were more commonly involved than the left lung. The mean CTSS was significantly higher in patients aged above 50 years (p<0.001). The mean CTSS of RT-PCR-negative patients was higher than that of RT-PCR-positive patients (15.18 vs. 14.31, p=0.537). Conclusion RT-PCR has a limited role in the diagnosis of COVID-19. The HRCT scan can detect typical COVID-19 findings even in patients with negative RT-PCR results. Moreover, the use of HRCT scan in determining the disease severity and extent of lung damage can lead to a better assessment of critically ill patients.

Investigating the Role of Ferritin in Determining Sexual Underdevelopment in Beta-Thalassemia Major Patients: A Cross-Sectional Analysis From Pakistan.

Background Beta-thalassemia major, a genetic disorder, delineates a vast spectrum of hematological and endocrinological complications. Elevated serum ferritin levels in beta-thalassemia patients represent various transfusion-related complications including infection, hemochromatosis, and severe iron overload that might lead to endocrinopathies such as hypogonadism leading to sexual underdevelopment. Our study, thus, aims to explore the role of ferritin in determining sexual underdevelopment in such patients.  Methods This multicentric cross-sectional study included a total of 120 beta-thalassemia patients. The sexual development of the patients was assessed using the Tanner staging system. Serum ferritin levels and other demographical parameters of the patients were collected. Independent-samples t-test, chi-square test, and receiver operating characteristic (ROC) curve were used to analyze the data. Results Out of 120 patients, 70 patients were males with a mean age of 18.95 ± 4.21 years. According to the Tanner staging system, 48 patients were sexually underdeveloped while 72 patients achieved sexual maturity. ROC curve analysis showed that ferritin levels at a cutoff value of 4900 mg/dL were 73.7% sensitive and 71.1% specific to predict sexual underdevelopment in beta-thalassemia patients. Conclusions Elevated serum ferritin levels were moderately sensitive and specific in predicting sexual underdevelopment in beta-thalassemia patients. This can serve as a low-cost parameter in determining sexual underdevelopment in such patients. More prospective cohort studies are needed to establish the association between elevated serum ferritin levels and sexual underdevelopment.
