Recurrent haemorrhagic venous infarct in a patient with sickle cell disease.

Cerebrovascular accidents are uncommon but devastating complications of sickle cell disease (SCD). Notably, cerebral sinovenous thrombosis is rarely reported in SCD and poses a therapeutic dilemma regarding anticoagulation. Herein, we describe a challenging case of a patient with sickle thalassaemia admitted to the hospital with recurrent haemorrhagic infarct secondary to cerebral sinus thrombosis.

Haemodynamic effects of intravenous acetaminophen in critically ill paediatric patients: a retrospective chart review.

Objectives: Haemodynamic changes following intravenous acetaminophen are well studied in adults. Limited data are published in critically ill paediatric patients, especially from the Middle East. We aim to investigate haemodynamic effects and incidence of hypotension with intravenous acetaminophen in critically ill children, with a focus on understanding factors influencing these effects.

Abdominal compartment syndrome secondary to chronic constipation in MECP2 duplication syndrome.

Abdominal compartment syndrome (ACS) is an infrequently encountered life-threatening disorder characterised by elevated abdominal pressure with evidence of new organ dysfunction. It is rarely reported in paediatrics. We describe an extremely unusual presentation of a 13-year-old boy with long-standing constipation who developed ACS complicated by refractory septic shock and multiorgan failure.

Clinical course of COVID-19 among immunocompromised children: a clinical case series.

Infection with SARS-CoV-2 represents a great source of concern and a new threat for immunocompromised patients. Limited studies are available on COVID-19 in immunocompromised children. This case series aimed to evaluate the clinical and laboratory characteristics, management and outcomes of COVID-19 in five children immunocompromised due to different underlying conditions.

Diagnosing inborn error of immunity following the presentation of a complicated acquired infection after MMRV vaccine administration.

Live vaccine-acquired infection should attest for the occurrence of inborn errors of immunity. Autosomal recessive immunodeficiency 31B, a result of a signal transducer and activator of transcription 1 genetic mutation, results in defected interferon pathways: interferon alpha/beta and interferon gamma. These interferons are crucial for the defence against viral and mycobacterial infections.

Adenovirus as a rare cause of acute necrotising encephalitis.

Adenovirus is a common cause of upper and lower respiratory tract infections. Rarely, neurological manifestations may occur, ranging from mild aseptic meningitis to potentially fatal acute necrotising encephalopathy (ANE). Very little is known in regards to the exact pathogenesis of ANE in association with adenovirus.

United Arab Emirates' Future Perspective: Converting Potential Organ Donors Into Actual Organ Donors in an Academic Setting.

Objectives: The wide gap between organ demand and supply has been exponentially increasing worldwide, resulting in longer wait lists for patients. In response, a few countries have started deceased-donor programs. Thus, establishing national self-sufficiency and optimizing the deceased donation process are crucial steps.

Thrombocytopenia-associated multiple-organ failure (TAMOF): recognition and management.

Thrombocytopenia-associated multiple-organ failure (TAMOF) is an increasingly fatal phenomenon that may be associated with sepsis. TAMOF results from immune dysregulation and impaired activity of A Disintegrin And Metalloproteinase with ThromboSpondin type 1 motif, member 13. Early recognition of this premorbid condition and specific management results in a significantly improved outcome.

A Retrospective Evaluation of Echocardiograms to Establish Normative Inferior Vena Cava and Aortic Measurements for Children Younger Than 6 Years.

Objectives: The ability to plot the inferior vena cava (IVC) size on a normal curve for pediatric patients may prove beneficial. First, in patients with normal cardiac anatomy who present in shock, assessing IVC size may be valuable for evaluating the degree of dehydration. Second, in children with heart disease, understanding how a child's IVC size compares to normal could be particularly beneficial for patients with right heart disease.

Inhaled β2-Agonist Therapy Increases Functional Residual Capacity in Mechanically Ventilated Children With Respiratory Failure.

Objectives: To test the hypothesis that in mechanically ventilated children with respiratory failure, aerosolized albuterol modifies functional residual capacity, lung mechanics, oxygen consumption, and hemodynamics.

Design: Prospective, self-control clinical trial.

Setting: A 24-bed PICU in a quaternary care, academic children's hospital.

Haemophagocytic lymphohistiocytosis associated with coccidiomycosis.

Haemophagocytic lymphohistiocytosis (HLH) is a rapidly fatal disease caused by dysregulated histiocytes leading to an excessive inflammatory reaction. While genetic forms of HLH exist, the most common form is acquired, frequently associated with infection. Here we report the first case of HLH associated with a coccidiomycosis infection.

Severe lactic acidosis and multiorgan failure due to thiamine deficiency during total parenteral nutrition.

A 16-year-old perioperative paediatric patient presented with refractory lactic acidosis and multiorgan failure due to thiamine-deficient total parenteral nutrition during a recent national multivitamin shortage. Urgent empiric administration of intravenous thiamine resulted in prompt recovery from this life-threatening condition. Despite readily available treatment, a high index of suspicion is required to prevent cardiovascular collapse and mortality.
