Authors: Gajapriya M  , Lavanya Govindaraju  
Published: December 2023

Background: Pediatric patients going through dental systems and who are incredibly uncooperative, unfortunate, restless, or actually safe without any assumption for conduct improvement are gone through for general anaesthesia (GA) to do the treatment. Changes in the training and advancement of general sedative medications have impacted the utilization of muscle relaxants and inversion specialists in pediatric patients. Aims: The aim of the review was to survey the commonly used muscle relaxant and reversal agents for pediatric patients treated under general anesthesia in Saveetha dental college from March 2020 to February 2021. Setting and Design: A retrospective study was conducted on pediatric patients treated under general anesthesia to determine the commonly used muscle relaxants and reversal agents. Materials and Methods: From pediatric patients visiting private dental hospital, those who are treated under general anesthesia from March 2020 to February 2021 considered as inclusion . Exclusion criteria involve those who are not treated under general anesthesia. The final sample size 100. The age , gender, muscle relaxants and reversal agents prescribed were considered and tabulated and SPSS (Statistical Package for the Social Sciences, Chicago,USA) was used to analyze the data. The results were compared using descriptive statistics and Chi-square-test. Then 0.05 was set to be a P value for the level of significance. Results: From the results of the study, atracurium(99%) and vecuronium(1%) were the commonly used muscle relaxants and neostigmine + glycopyrrolate(100%) was the commonly used reversal agents for pediatric patients treated under general anesthesia. Conclusions: From the study , there were only a few standard drugs like atracurium and vecuronium used as muscle relaxant and neostigmine + glycopyrrolate reversal agents were used for pediatric patients who were treated under general anesthesia .

Yetişme ortamları bitkilerden elde edilen ürünlerin kalitesine birçok yönden etkileyebilir. Farklı oranlarda kimyasal madde içeren meyveler, özelliklerin farklı olmasına neden olabilir. Bu çalışmada, Isparta Orman Bölge Müdürlüğü yetki alanındaki dört farklı coğrafi bölgeden toplanan Çilek Ağaçlarından (Arbutus andrachne L.) toplanan meyvelerin bazı özellikleri incelenmiştir.
Meyve örnekleri arasında önemli fizikokimyasal farklılıklar bulunmuştur. Numuneler arasında en yüksek renk farklı numune IV (ΔE: 15,4) ile ve daha sonra sırasıyla numune I (ΔE: 15,1), numune III (ΔE: 7,6) ve numune II (ΔE: 3,6) de gözlemlenmiştir. Ancak meyvelerin boyut özellikleri (çap ve ağırlık) bazı farklılıklar göstermektedir. En yüksek ortalama çap (12,42 mm) ve ağırlık (1,13 g) ile birlikte şeker içeriği 33,81 °Bx ile numune I'de hesaplanmıştır. Numuneler arasında şeker oranı, fark edilebilir olarak daha düşük çapa sahip fakat daha yüksek ağırlığa sahip meyvelerde hesaplanmış, çap artışı ile ağırlık azalması arasında ilişki gözlemlenmiştir. Ayrıca, numune I için 43 ve numune IV için 35 uçucu yağ bileşiği tespit edilmiş, bunlardan 31'inin her iki meyve örneklerinde de olduğu anlaşılmıştır. Bu ortak bileşikler, toplam uçucu yağ oranının numune I için %97.07’ini numune IV için ise %91,78’ini oluşturduğu hesaplanmıştır. Bu çalışmada elde edilen verilerden, A. andrachne meyvelerinin fizikokimyasal özelliklerinin, coğrafi yetişme ortamlarının açıklanması bakımından bir gösterge olabileceği olarak değerlendirilmiştir.
Determination of Phenolic Contents and Antioxidant Activities in Different Solvents of Hatila Valley and Macahel Bee Products in Artvin, Turkey
Authors: BOZKUŞ Tuğba Nigar 
Published: December 2023

This study determines the extracts of bee products prepared with different solvents in terms of phenolic content and antioxidant activity of the Hatila Valley and Macahel region of Artvin, Turkey. For this purpose, water and ethanol extracts of royal jelly and honey; water, ethanol, 70% ethanol, propylene glycol and 70% propylene glycol extracts of pollen and propolis were analyzed by total polyphenol and flavonoid content, and ferric reducing power.
The results of the analyzes indicated that Macahel honey and propolis had higher phenolic content and antioxidant activity than Hatila honey and propolis. Hatila bee products were ranked as propolis > pollen > royal jelly > honey in terms of phenolic content and antioxidant activity. The antioxidant activities of Hatila Valley and Macahel bee products vary depending on the amount of phenolic compounds in their structures. Furthermore, when Hatila, Macahel, and Hatila + Macahel propolis were compared in terms of polyphenol and flavonoid content and ferric reducing power, the order was Macahel propolis > Hatila + Macahel propolis > Hatila propolis. A statistically significant difference was found between 70% ethanol and 70% propylene glycol and water, and although these solvents had higher solubility, the lowest solubility was in water. These differences vary depending on the geographical location, botanical and climatic variations of the region where the bee products are collected, and the solvent used for the extraction. Therefore, rather than using a single propolis sample for various sectors such as the food, medical and cosmetic industries, propolis mixtures may be suitable for different applications.

Published: December 2023

Appearance of unexpected masses in the chambers of the heart during cardiac surgery can be intriguing. We report the case of a mass in the left ventricle that appeared at the time of separation from cardiopulmonary bypass in a child after a complex intracardiac repair. The child presented for surgery to a tertiary care hospital in Muscat, Oman, in 2022. Prior to the surgical repair the mass was not appreciated by echocardiography. An intraventricular baffle was used to divert left ventricular blood flow towards the outflow tract, after which an intraventricular “mass” was observed. Intraoperative transoesophageal echocardiography identified the mass as a portion of the interventricular septum that was located between the inlet and outlet ventricular septal defects.

Published: December 2023

Sinus venosus atrial septal defects present a wide variety of anatomical features and are frequently associated with partial anomalous pulmonary venous drainage of one or more right pulmonary veins. Surgical correction used to be the standard treatment. In recent times, transcatheter correction of superior sinus venosus atrial septal defects has come into vogue. The transcatheter closure of these defects with covered stents at a tertiary care centre in Oman between 2018 and 2023 is reported.

Published: December 2023

Objectives: There is limited data published from outside North America and Europe comparing the outcomes of a modified Blalock-Taussig shunt (MBTS) and ductal stenting as the first palliative procedure for infants with duct-dependent pulmonary circulation. This study reports the National Heart Center’s, in Muscat, Oman, experience in comparing the outcomes of these 2 interventions. Methods: This retrospective study included all infants with duct-dependent pulmonary circulation who received either a MBTS or ductal stenting from 2016–2019. The primary outcomes were death or re-interventions. Secondary outcomes included death, subsequent re-interventions, survival to subsequent surgical intervention, survival to hospital discharge, post-procedural mechanical ventilation and duration of intensive care unit stay. Results: A total of 71 patients were included in the study, 33 (46%) of whom received ductal stenting. The prevalence of the primary outcome (death or re-intervention) in the patent ductus arteriosus (PDA) stent group was 54.5% versus 31.6% in the MBTS group but this was not statistically significant (P = 0.06). There was no difference between the 2 groups in terms of time to next surgical intervention (P = 0.233). The PDA stent group had shorter post-procedural, mechanical ventilation and intensive care unit stay durations (P <0.05). Syndromic patients were at higher risk of mortality compared to non-syndromic patients. Conclusion: MBTS and ductal stenting are both acceptable modalities as a palliative intervention for infants with duct-dependant pulmonary circulation. Syndromic patients are at higher risk of mortality. This can be considered an important factor for patient selection.

Authors: Al-Kindi Saba , Al-Hajriy Mahmood , Al-Jabri Adil 
Published: December 2023

Angiomyolipoma is a common benign solid tumour that accounts for up to 3% of all renal tumours; most of the cases are sporadic. However, it can be part of other diseases. Angiomyolipomas are usually found incidentally through unrelated clinically indicated images but also, they can be diagnosed after complications have occurred. We report the case of retroperitoneal haemorrhage following the rupture of renal angiomyolipoma post-fibrinolysis, we are highlighting such a rare condition, the management options and the follow-up plan. The management of angiomyolipomas ranges from conservative treatment to surgical intervention depending on the patient’s condition and the tumour’s radiological features. Following-up on patients with angiomyolipomas depends on the symptoms and the tumour size. Till date, there is no reported cases of renal angiomyolipoma rupture post-fibrinolysis therapy as a treatment for myocardial infarction in non-percutaneous intervention capable facility.

The Sinus Venosus Veno-Venous Bridge

Published: December 2023

This review provides an update on the morphology of the sinus venosus defect. It was earlier believed that a 'common wall' separated the right pulmonary veins from the superior caval vein. In the sinus venosus defects, this wall was absent. Current evidence shows that the superior rim of the oval fossa, rather than forming a second septum or representing a common wall, is an infolding between the walls of the caval veins and the right pulmonary veins. The sinus venosus defect is caused by the anomalous connection of one or more pulmonary veins to a systemic vein. However, the pulmonary vein(s) retain their left atrial connections, leading to a veno-venous bridge that allows interatrial shunting outside the oval fossa. True atrial septal defects are located within the oval fossa or in the anteo-inferior buttress, while sinus venosus defects, ostium defects and coronary sinus defects are morphologically distinct from them.

Published: December 2023

Objectives: Post-infarction ventricular septal defect (VSD) is one of the known complications after acute myocardial infarction. This study investigated the clinical results after surgical repair of VSD. Methods: This retrospective study included all patients undergoing surgical repair of VSD from 1996 to 2020 in Oman. Results: Out of a total of 75 patients, 62.5% were men, with a mean age of 59 years. The mean follow-up was 17.2 (7.5) years. Of the 75 patients, 34 (45.3%) patients died within 30 days. Total survival was 41.3% at 5 years, while the 10-year survival rate was 33.3%. Outcomes and predictors for 30 days mortality were the number of concomitant coronary involvement and anastomoses performed, residual postoperative shunt and postoperative dialysis. Conclusion: Even with surgical repair, early mortality of post-infarction septal defect is still considerably high. Early repair and the anatomically posterior rupture are predictors of early mortality. In patients surviving the immediate postoperative period, long-term survival is limited by pre-existing coronary artery disease, postoperative renal failure and the presence of a residual postoperative shunt.

Published: December 2023

Objectives: This study aimed to identify angiographic features that would predict myocardial viability after coronary intervention for ST elevation myocardial infarction (STEMI). Methods: This retrospective study included patients who attended Sultan Qaboos University Hospital, Muscat, Oman, between January and December 2019 with a STEMI. Results: A total of 72 patients (61 male; mean age = 54.9 ± 12.7 years) were included in the study; 11 patients had evidence of non-viability on echocardiography. There were 13 patients with viable myocardium and 3 with non-viable myocardium who had a myocardial blush grade (MBG) of 2 or lower. Similarly, 10 patients with viability and 1 with non-viable myocardium had thrombolysis in myocardial infarction (TIMI) flow of 2 or lower in the infarct related artery (IRA). However, none of these were statistically significant. The TIMI flow in the IRA at the end of the procedure correlated with the MBG. Conclusion: There were no clear angiographic features during primary angioplasty that could predict myocardial viability.

Published: December 2023

With the focus on an idiographic approach whereby the observations incorporated the various dimensions of individual functioning ‘top-down’ to ‘bottom-up’, this case report describes the successful management of a 14-year-old girl with Kearns-Sayre syndrome and Dyggve-Melchior-Clausen disease requiring a transvenous permanent pacemaker implantation for complete heart block. The patient presented to a tertiary care centre in Muscat, Oman, in 2023 seeking consultation. The current idiographic approach appears to have a heuristic value for 2 interrelated reasons. Firstly, it is unlikely that even tertiary care units can accrue such rare presentations and scrutinise them under nomothetic approach. Secondly, by employing the idiographic approach that is capable of examining each case in-depth, the aspiration for good health and well-being may come to the forefront. To the best of the authors’ knowledge this is the first published idiographic report in anaesthesia care.

Published: December 2023

Objectives: This study aimed to identify the incidence of sudden cardiac death (SCD0 in adult patients under the age of 49 years, including adolescents with an out-of-hospital cardiac arrest that presented to the emergency department of a tertiary care hospital. Methods: This retrospective cross-sectional study was conducted at the Royal Hospital, Muscat, Oman, between January 2015 and December 2019. All patients with out-of-hospital cardiac arrest were enrolled. The incidence of SCD was evaluated. Information about the patient's demographic data, the site of cardiac arrest, the mode of arrival, the duration of pre-arrest symptoms and if cardiopulmonary resuscitation was performed was gathered. Survival data at 3-year follow-up was obtained. Results: A total of 117 out of 769 (15%) patients met the criteria for SCD. Male gender was predominant, with a median age of 33 years. In about 79.5% of the patients, cardiac arrest was witnessed. Only 43 patients (36.8%) received cardiopulmonary resuscitation at the arrest site; 21 patients (17.9%) had a shockable rhythm and 96 patients (82.1%) had a non-shockable rhythm. Spontaneous circulation was returned in 15 patients (12.8%). Nine patients (7.7%) were discharged from the hospital and 8 (6.8%) survived at least 36 months. Conclusion: The study findings indicate the prevalence of SCD among patients who experienced a cardiac arrest outside the hospital. Unfortunately, only a small number of patients were able to survive in the long term. By implementing preemptive screening for individuals and their families, it may be possible to prevent SCD and improve outcomes for those affected.

Published: December 2023

Background
Current postpartum hemorrhage (PPH) risk stratification is based on traditional statistical models or expert opinion. Machine learning could optimize PPH prediction by allowing for more complex modeling.

Objective
We sought to improve PPH prediction and compare machine learning and traditional statistical methods.

Methods
We developed models using the Consortium for Safe Labor data set (2002-2008) from 12 US hospitals. The primary outcome was a transfusion of blood products or PPH (estimated blood loss of ≥1000 mL). The secondary outcome was a transfusion of any blood product. Fifty antepartum and intrapartum characteristics and hospital characteristics were included. Logistic regression, support vector machines, multilayer perceptron, random forest, and gradient boosting (GB) were used to generate prediction models. The area under the receiver operating characteristic curve (ROC-AUC) and area under the precision/recall curve (PR-AUC) were used to compare performance.

Results
Among 228,438 births, 5760 (3.1%) women had a postpartum hemorrhage, 5170 (2.8%) had a transfusion, and 10,344 (5.6%) met the criteria for the transfusion-PPH composite. Models predicting the transfusion-PPH composite using antepartum and intrapartum features had the best positive predictive values, with the GB machine learning model performing best overall (ROC-AUC=0.833, 95% CI 0.828-0.838; PR-AUC=0.210, 95% CI 0.201-0.220). The most predictive features in the GB model predicting the transfusion-PPH composite were the mode of delivery, oxytocin incremental dose for labor (mU/minute), intrapartum tocolytic use, presence of anesthesia nurse, and hospital type.

Conclusions
Machine learning offers higher discriminability than logistic regression in predicting PPH. The Consortium for Safe Labor data set may not be optimal for analyzing risk due to strong subgroup effects, which decreases accuracy and limits generalizability.
