Background: Attention-deficit/hyperactivity disorder (ADHD) is now acknowledged as a significant public health concern, a persistent neurodevelopmental disorder. It poses challenges across various life domains, persisting into adulthood, and is often undiagnosed. From July 2023 to December 2023, this study investigated the prevalence, types, participants' knowledge and perceptions, and demographic determinants of undiagnosed adult ADHD among undergraduate medical students in Pakistan.

Article Synopsis
  • * While echocardiography is effective for native valve infections, its accuracy drops for prosthetic valves and devices like pacemakers, leading to interest in advanced imaging techniques such as CT, MRI, and PET for better diagnosis.
  • * This article reviews existing research on the diagnostic value of these advanced imaging methods for prosthetic valve endocarditis and device infections, highlighting inconsistencies and the need for further evaluation in clinical management.

Coronary embolism (CE) is an infrequent etiology of myocardial infarction secondary to embolization of occlusive thrombi within the coronary arteries, typically arising in patients with pre-existing atrial fibrillation. Clinical presentation is similar to atherosclerotic myocardial infarction, however the condition is likely underrecognized. The simultaneous presence of other embolic manifestations may assist with diagnosis, although definitive therapy, medical or interventional, remains inconclusive.

Article Synopsis
  • Clear and trustworthy information is essential for increasing COVID-19 vaccination acceptance among pregnant women, particularly due to their heightened risk for severe complications from the virus.
  • A study conducted in Jeddah, Saudi Arabia, compared pregnant women who received the COVID-19 vaccine to those who did not, assessing adverse events and pregnancy-related complications.
  • Results showed that women who were vaccinated (Group B) experienced higher instances of certain complications but had lower COVID-19 rates post-vaccination, indicating the vaccine's potential benefits despite some risks.

Article Synopsis
  • - Granulomatosis with polyangiitis (GPA) is a rare vasculitis that primarily impacts small to medium blood vessels, often affecting the airways and kidneys.
  • - Cardiac involvement in GPA is uncommon and typically doesn't present as the first symptom, making this case noteworthy.
  • - A 44-year-old man experienced a heart issue that led to the diagnosis of GPA, showcasing vasculitis in the coronary arteries and myocarditis; he was treated with steroids, rituximab, and avacopan.

Patients with atrial fibrillation/atrial flutter (AF) are notoriously predisposed to thromboembolic events secondary to the development of thrombi within the left atrium of the heart. AF accompanied by a fairly decent CHA2DS2-VASc score is a known indication for full anticoagulation, frequently with direct oral anticoagulants (DOACs), such as apixaban. Following extensive studies weighing the benefits of anticoagulation versus risks of major bleeding, patients meeting two or more of the dose-reduction criteria (age ≥80 years, weight ≤60 kg, and/or creatinine ≥ 1.

Dynamins are an essential superfamily of mechanoenzymes that remodel membranes and often contain a "variable domain" important for regulation. For the mitochondrial fission dynamin, dynamin-related protein 1, a regulatory role for the variable domain (VD) is demonstrated by gain- and loss-of-function mutations, yet the basis for this is unclear. Here, the isolated VD is shown to be intrinsically disordered and undergo a cooperative transition in the stabilizing osmolyte trimethylamine N-oxide.

Pulmonary embolism is a significant complication of N-butyl-2-cyanoacrylate, commonly known as histoacryl, used to sclerose bleeding gastroesophageal varices. We present a 50-year-old female with seronegative chronic liver disease who was managed with endoscopic histoacryl injection sclerotherapy for bleeding gastric fundal varices. Following treatment, the patient developed sudden respiratory distress due to multiple pulmonary glue emboli, requiring inpatient supportive care along with close monitoring for a week.

The coronavirus disease 2019 (COVID-19) pandemic has deteriorated the healthcare system and economy worldwide. Globally, by making the primary vaccination against the coronavirus necessary, the surge in cases waned, but as the effects of this vaccination decreased after some time, to prevent another pandemic, vaccination was still necessary. As a result, receiving a COVID-19 booster shot can boost immunity against the coronavirus.

Dynamins are an essential superfamily of mechanoenzymes that remodel membranes and often contain a "variable domain" (VD) important for regulation. For the mitochondrial fission dynamin, Drp1, a regulatory role for the VD is demonstrated by mutations that can elongate, or fragment, mitochondria. How the VD encodes inhibitory and stimulatory activity is unclear.

Objective: To assess the outcome of endovascular treatment of intracranial aneurysm over 15 years.

Methods: The retrospective study was conducted at the at Radiology Department of Aga Khan University Hospital, Karachi, and comprised medical records from April 2003 to April 2018 of patients who received endovascular treatment for intracranial aneurysm. Multiple variables reviewed included demographics, clinical presentation, aneurysm morphology, technique used, technique outcome and clinical outcome.

Background Acute kidney injury (AKI) is a commonly recognized clinical problem after congenital heart disease (CHD) surgery. Increased perioperative morbidity, development of chronic kidney disease, and increased mortality are the major concerns. We investigated frequency, risk factors, and outcomes of AKI after CHD surgery at our hospital.

Background And Purpose: There is a paucity of literature related to the neuroimaging of CNS tuberculosis (TB) and largely covers pediatric CNS TB. The objective of this study was to determine the frequency of different forms of CNS TB and its associated complications and to study longitudinal disease course using computed tomography (CT) and MRI.

Methods: Retrospective chart and imaging review of patients diagnosed with CNS TB in a tertiary care hospital in Pakistan over a 10-year period.
