Intussusception in an infant as a manifestation of COVID-19

Gastrointestinal manifestations of COVID-19 are rare and have primarily been limited to diarrhea or vomiting. Intussusception is the most common cause of bowel obstruction in infants, with up to 30% of pediatric intussusception cases having a preceding viral illness. We present the rare case of intussusception in a SARS-CoV-2 positive infant. This is the first documented case of survival in a SARS-CoV-2 positive patient presenting with intussusception as the primary manifestation. As our knowledge of this disease evolves, surgeons need to remain suspicious for possible gastrointestinal manifestations of COVID-19

Amoebic liver abscess: Outcomes of percutaneous needle aspiration vs drain placement in paediatric population

Objective: To compare the effectiveness of percutaneous catheter drain placement with percutaneous needle aspiration in terms of hospital stay, time to resolution of symptoms and cost of intervention performed.Methods: The retrospective cohort study was conducted at Aga Khan University Hospital, Karachi, and comprised data of patients with amoebic liver abscess from, January 2006 to December 2016 which was collected using non-probability purposeful sampling. Primary outcome included length of hospital stay, time to resolution of symptoms and cost of intervention. Secondary outcomes included development of complications, need for re-intervention and abscess resolution. SPSS 22 was used for data analysis. .Results: Of the 62 patients, 36(58%) underwent percutaneous needle aspiration Group A, and 26(42%) were treated with percutaneous catheter drain placement Group B. Both groups were malnourished and anaemic at presentation. Overall, 56(90.3%) patients had single abscess and 44(71%) had it in the right lobe. Mean duration of symptoms was less in Group B compared to Group A (11.2±4.5 versus 16.4±3.2 days). Mean abscess size was 6.13cm ± 9.75cm in Group A and 7.40cm ± 8.40cm in Group B. The mean length of hospital stay Group A was shorter than in Group B (p=0.047) with earlier resolution of symptoms (p=0.027).Conclusion: Both methods were found to be effective in treating amoebic liver abscess in children, but percutaneous needle aspiration was more effective

Simulation-based training in the paediatric surgery population: A review of current trends and future direction

In recent years, simulation-based training in surgery has emerged as a viable accompaniment to traditional teaching methods. Multiple studies have highlighted the benefits of simulation-based training in both learning and teaching aspects of surgical training, with a particular emphasis on the honing of technical skills. However, multiple issues still exist in widespread implementation of simulation-based training, especially in the developing countries. Furthermore, the existing literature needs to be expanded upon in both quantity and quality domains to ensure a more evidence-based transition to simulation-based training in surgery. The current review article was planned to take a look at the existing literature on the current state of simulation-based training in paediatric surgery, its potential to revolutionise paediatric surgical training, and to propose solutions to the issues that are delaying wider implementation

Infantile haemangioendothelioma of the parotid gland: Case report and review of literature

Haemangioendotheliomas (HAE), although rare but are the most common parotid gland tumours in children. We report a 4-month-old girl who presented with a progressively enlarging right sided facial swelling overlying the angle of the mandible. An Ultrasound of the lesion and a computed tomography (CT) scan of the head and neck was carried out which revealed a large lesion within the right parotid gland. CT scan further demonstrated a direct communication with the right external carotid artery and external jugular vein. Considering the clinical course and radiological findings, there was sufficient evidence to avoid any invasive testing. Due to the self-limiting nature of the disease, patient was managed expectantly

Response of Starter Broiler Chickens to Feed Diets Treated with Organic Acids

Background: Organic acids contain one or more carboxylic acid groups which are linked with covalent bond and  have acidic properties that can enhance the reservation of protein and some other nutrients in birds. Antibiotic growth promoters have been banned due to their residues that remain in the meat and effects the human beings. Therefore, the organic acids are used as their alternatives. The present study is aimed to inspect the outcome of organic acids on uptake of feed, feed gain ratio, and live weight gain in broiler chickens.Methods: A total of 150 unsexed broiler chickens were used for this experiment which were having five categories of treatment as T1, T2, T3, T4, and T5. Each category had thirty birds. T1 was treated with a standard diet, T2was treated with acetic acid, T3 with butyric acid, T4 with citric acid and T5 with formic acid.  The duration of this experiment was 28 days. After the specified time of this experiment, the data of uptake of feed and body weight was gathered on weekly basis.  Comparison of all the five treatments was done by using the Duncan's multiple range test.Results: Feed Conversion Ratio (FCR) was found lower in T5 than other treatments. T5 group showed the highest average value of final body weight of broilers in contrast to the T3 group which showed the lowest final body weight.  Feed intake was found significantly different within the treatments. T3 showed significantly lower value as compared to other treatments. The lowest value of average regular uptake of grains was found in T3 treatment group. Broilers fed on formic acid have shown a better protein efficiency ratio than that of butyric acid and citric acid. Broilers treated with citric acid have a significant difference which indicates more water consumption as compared to other treatments.Conclusion: Organic acids have a productive effect on the growth of animals and broiler chickens. Organic acids including butyric acid, acetic, citric, formic, fumaric, and propionic acid vary in their biochemical actions in the system of animals. Organic acid affects the final weight gain, average regular gain in weight, total uptake of feed, and feed to gain ratio, daily intake of protein, protein efficiency ratio, total water uptake, average water intake, and water feed ratio. Based on the present study, further analysis is required to look over the impacts of addition of organic acid on the growth accomplishment of broiler chicks.Keywords: Broiler chicks; Organic acid; Butyric acid; Citric acid; Acetic acid; Formic acid 

A Systematic Review on Clinical Safety and Efficacy of Vancomycin Loading Dose in Critically Ill Patients

Background: The clinical significance of utilizing a vancomycin loading dose in critically ill patients remains unclear. Objective: The main aim of this systematic review is to evaluate the clinical safety and efficacy of the vancomycin loading dose in critically ill patients. Methods: We performed a systematic review using PRISMA guidelines. PubMed, the Web of Science, MEDLINE, Scopus, Google Scholar, the Saudi Digital Library and other databases were searched. Studies that reported clinical outcomes among patients receiving the vancomycin LD were considered eligible. Data for this study were collected using PubMed, the Web of Science, MEDLINE, Scopus, Google Scholar and the Saudi Digital Library using the following terms: “vancomycin”, “safety”, “efficacy” and “loading dose” combined with the Boolean operator “AND” or “OR”. Results: A total of 17 articles, including 2 RCTs, 11 retrospective cohorts and 4 other studies, met the inclusion/exclusion criteria out of a total 1189 studies. Patients had different clinical characteristics representing a heterogenous group, including patients in critical condition, with renal impairment, sepsis, MRSA infection and hospitalized patients for hemodialysis or in the emergency department. Conclusions: The study shows that the target therapeutic level is achieved more easily among patients receiving a weight-based LD as compared to patients received the usual dose without an increased risk of new-onset adverse drug reactions

The medical and biochemical knowledge of health care professionals regarding the management of MERS-CoV: lessons from 2019 pilgrimage season in Al-Madinah, Saudi Arabia: A cross-sectional study

Background: Middle East respiratory syndrome coronavirus (MERS-CoV) epidemic was a serious healthcare concern not responding to conventional anti-viral therapies between 2012 and 2017 with high fatality rates. Saudi Arabia is still among the best world examples in combating both MERS-CoV and COVID-19 pandemics. Objectives: Investigating the medical and biochemical knowledge of healthcare professionals in Al-Madinah, Saudi Arabia on preventive, diagnostic and therapeutic measures against MERS-CoV epidemic. Subjects and methods: In 2019, this cross-sectional study included 416 healthcare personnel of which 402 participants answered the questions with a response rate of 96.7%. Specialties of participants were medical students (1.4%), physicians (64.4%), nurses (23.6%) and others (10.7%). Results: The vast majority of the investigated healthcare personnel gave the right answers. 96.7% of the participants answered that washing hands using water helps prevent MERS-CoV. 90.8% of the participants answered that wearing a clean non-sterile long-sleeved gown and gloves does helps prevent MERS-CoV infection. 94.7% of participants answered that using alcohol-based hand rub helps prevent MERS-CoV infection. 92.03% of the participants thought that wearing protective equipment does help preventing MERS-CoV infection. 86.1% answered that there is no vaccine available against MERS-CoV infection and 86.1% answered that taking vaccines is suitable for preventing MERS-CoV infection. 90.04% of the participants answered that MERS-CoV patients should be diagnosed using PCR and 84.3% thought that the highest levels of anti-CoV antibodies are in abattoir workers while 87.8% thought that isolation of suspected cases helps preventing MERS-CoV infection. Conclusion: The investigated healthcare workers had a satisfactory knowledge on the preventive and therapeutic measures and biochemical knowledge against MERS-CoV epidemic at mass gatherings as pilgrimage season

Effects of a high-dose 24-h infusion of tranexamic acid on death and thromboembolic events in patients with acute gastrointestinal bleeding (HALT-IT): an international randomised, double-blind, placebo-controlled trial

Background: Tranexamic acid reduces surgical bleeding and reduces death due to bleeding in patients with trauma. Meta-analyses of small trials show that tranexamic acid might decrease deaths from gastrointestinal bleeding. We aimed to assess the effects of tranexamic acid in patients with gastrointestinal bleeding. Methods: We did an international, multicentre, randomised, placebo-controlled trial in 164 hospitals in 15 countries. Patients were enrolled if the responsible clinician was uncertain whether to use tranexamic acid, were aged above the minimum age considered an adult in their country (either aged 16 years and older or aged 18 years and older), and had significant (defined as at risk of bleeding to death) upper or lower gastrointestinal bleeding. Patients were randomly assigned by selection of a numbered treatment pack from a box containing eight packs that were identical apart from the pack number. Patients received either a loading dose of 1 g tranexamic acid, which was added to 100 mL infusion bag of 0·9% sodium chloride and infused by slow intravenous injection over 10 min, followed by a maintenance dose of 3 g tranexamic acid added to 1 L of any isotonic intravenous solution and infused at 125 mg/h for 24 h, or placebo (sodium chloride 0·9%). Patients, caregivers, and those assessing outcomes were masked to allocation. The primary outcome was death due to bleeding within 5 days of randomisation; analysis excluded patients who received neither dose of the allocated treatment and those for whom outcome data on death were unavailable. This trial was registered with Current Controlled Trials, ISRCTN11225767, and ClinicalTrials.gov, NCT01658124. Findings: Between July 4, 2013, and June 21, 2019, we randomly allocated 12 009 patients to receive tranexamic acid (5994, 49·9%) or matching placebo (6015, 50·1%), of whom 11 952 (99·5%) received the first dose of the allocated treatment. Death due to bleeding within 5 days of randomisation occurred in 222 (4%) of 5956 patients in the tranexamic acid group and in 226 (4%) of 5981 patients in the placebo group (risk ratio [RR] 0·99, 95% CI 0·82–1·18). Arterial thromboembolic events (myocardial infarction or stroke) were similar in the tranexamic acid group and placebo group (42 [0·7%] of 5952 vs 46 [0·8%] of 5977; 0·92; 0·60 to 1·39). Venous thromboembolic events (deep vein thrombosis or pulmonary embolism) were higher in tranexamic acid group than in the placebo group (48 [0·8%] of 5952 vs 26 [0·4%] of 5977; RR 1·85; 95% CI 1·15 to 2·98). Interpretation: We found that tranexamic acid did not reduce death from gastrointestinal bleeding. On the basis of our results, tranexamic acid should not be used for the treatment of gastrointestinal bleeding outside the context of a randomised trial
