Efficacy of Nasal Continuous Positive Airway Pressure versus Heated Humidified High-Flow Nasal Cannula as a Primary Mode of Respiratory Support in Preterm Infants with RDS

Objective: To determine the efficacy of nasal continuous positive airway pressure (NCPAP) versus heated humidified high-flow nasal cannula (HHHFNC) as a primary mode of respiratory support in preterm infants with respiratory distress. Methodology: This randomized controlled trial study was conducted at in-patient department of neonatology (Nursery & NICU) of Pakistan Insitute of Medical Sciences (PIMS) from July 2020 to Dec 2020. A total of 280 neonates randomly divided (140 in each study group) of both genders, with gestational age between 28-34 weeks and having mild-to-moderate respiratory distress within 1st 6 hours of birth requiring non-invasive ventilation were enrolled. Neonates in NCPAP Group (n=140) were given NCPAP whereas neonates in HHHFNC Group (n=140) were given HHHFNC. The efficacy of both groups were compared on the basis of treatment failure within 1st 3 days, total duration (hours) of non-invasive ventilator (NIV) required and total duration (hours) of supplementary oxygen required. Results: Overall, mean gestational age was noted to be 30.0+6.4 weeks. There were 144 (51.4%) neonates with birth weight between 1 to 1.4 kg, 90 (32.1%) between 1.5 to 1.9 kg and 46 (16.4%0 between 2.0 to 2.4 kg. Treatment failure was noted in 67 (47.6%) neonates in NCAP group while HHHFNC group reported 73 (52.4%) neonates with treatment failure (p=0.4733). No significant difference was observed in mean total duration of NIV support required (p=0.2598) or mean total duration of supplementary oxygen (p=0.1946) in between study groups. Conclusion: HHHFNC had similar efficacy when compared to NCPAP among neonates with RDS. In comparison to NCPAP, HHHFNC could be a simple, well-tolerated and effective alternative in terms of respiratory support. No major difference in terms of complication was observed between both treatment approaches.

Comparison of Radiation Dose in CT Examinations At PIMS with European Commission Reference Doses

OBJECTIVE - The purpose of this study was to assess the radiation dose levels from common computed tomography (CT) examinations performed in Radiology Department of Pakistan Institute of Medical Sciences (PIMS), and evaluate these according to diagnostic reference levels (DRLs) proposed by European Commission (EC) guidelines, and thus contributing towards the establishment of local and national DRLs. To the best of our knowledge, this is the first study of its kind to explore radiation doses from CT examinations in Pakistan. STUDY DESIGN - This was a quantitative study conducted at PIMS, Islamabad, spanning a duration of eight weeks. Scan parameters and dose profile data of 1506 adults undergoing examinations of head, neck, chest and abdomen-pelvis regions, comprising of single- and multi-phase, contrast-enhanced and unenhanced studies. Dose indicators utilized by EC guidelines for DRLs include volume CT dose index (CTDIvol) and Dose Length Product (DLP) for single slice and complete examination radiation doses, respectively. METHOD - Values of CTDIvol, DLP and scan lengths were extracted from the CT operators console. Other control variables included gender, contrast enhancement and phasicity of study. IBM SPSS package was used to obtain descriptive statistics such as mean and quartiles. RESULTS - DRLs calculated as 75th percentile of CTDIvol, DLP for various anatomical regions are by and far comparable to European DRLs. CONCLUSION – This study describes institutional diagnostic reference levels for common CT exams in Islamabad and provides benchmark values for future reference. Our DRL values are mostly comparable to European and international DRLs. Similar, albeit large scale, surveys are recommended for establishment of local and national DRLs, eventually contributing towards development of regional DRLs.

Comparison of Alveolar Osteitis (AO) occurrence after impacted mandibular third molar removal with and without post-extraction socket irrigation

Objective: We wanted to see whether impacted third mandibular molar extractions resulted in Alveolar Osteitis if post-extraction socket irrigation was used or not. Methodology: A randomized control experiment on 70 patients study was conducted from July 2019 to January 2020 at Islamabad Dental Hospital's OMFS department. Patients presenting with the mandibular third molars fulfilling the inclusion criteria had their teeth extracted with and without socket irrigation using the computer lottery method. In cases of dry socket, clinical diagnosis was made between the 3rd, 5th, and 7th postoperative days. Results: 70 patients/sockets were evaluated with 35 having been irrigated and 35 non-irrigated. The age range was 16-50years with a mean of 29.49 and most patients were between the 16-35 age group. There were 48.6% males and 51.4% females. Dry Socket was evaluated on the 3rd, 5th, and 7th day between groups (A=irrigation, B=Non-irrigation). On the 3rd postop day, 14 (40%) patients in group A and 15(42.9%) patients were diagnosed as dry Sockets. A similar number of patients in both groups (20%) exhibited symptoms of dry socket on the fifth and seventh postoperative days, as did 5 (14.3 %) in group A, 3 (8.6 %) in group B, and 1(2.9 %t) in group A, all on the fifth postoperative day. Conclusion: On the third, fifth, and seventh postoperative days, there was no significant difference in the result of Alveolar Osteitis between the groups.
