, a slow-growing non-tuberculous mycobacterium (NTM), presents diagnostic challenges due to its resemblance to and other NTMs. While NTM infections and tuberculosis share clinical and radiological features, their management strategies differ. Accurate differentiation is pivotal, as misdiagnosing NTM infections such as MDR-TB can lead to ineffective treatments.

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a rare genetic disorder caused by mutations in the NOTCH3 gene, resulting in subcortical infarctions and leukoencephalopathy. It predominantly affects the brain's small blood arteries, resulting in repeated ischemic episodes including transient ischemic attacks and strokes leading to cognitive impairment and mental symptoms. We provide a case study of a 25-year-old patient suspected of having meningoencephalitis.

We present a rare case of a 25-year-old woman who developed idiopathic portal hypertension and ascites four days after delivering a stillborn child at term. She had no previous liver illness or risk factors for portal vein thrombosis. Investigations revealed a dilated portal vein, esophageal varices, and high serum-albumin gradient ascites, all of which point to a presinusoidal etiology of portal hypertension.

Idiopathic basal ganglia calcification (IBGC), also known as Fahr's disease, is a rare neurological disorder characterized by metabolic, biochemical, neuroradiological, and neuropsychiatric alterations resulting from symmetrical and bilateral intracranial calcifications. In most cases, an autosomal dominant pattern of inheritance and genetic heterogeneity is observed. Neuropsychiatric symptoms with movement disorders account for 55% of the manifestations of this disease.

Superior mesenteric artery syndrome (SMAS) is a specific type of duodenal obstruction marked by a blockage of the inferior part of the duodenum as a result of compression between the superior mesenteric artery (SMA) and the aorta. Depletion of the mesenteric fatty pad causes this complication. In the current study, we describe a case of SMAS involving a 36-year-old lady who presented with postprandial pain, weight loss, and hematemesis.

Background: SARS-CoV-2 vaccination of all age-eligible populations is an important part of the COVID-19 pandemic response. In Ontario, vaccination coverage in 5-to-11-year-old children has remained lower than in other age groups. We sought to understand pediatricians' perception, practices, and barriers to SARS-CoV-2 vaccination in children, particularly children aged 5-to-11 years, to inform interventions and promote capacity of pediatricians as vaccinators and vaccination promoters.

Article Synopsis
  • Several studies have indicated a potential link between vitamin D levels in childhood and autism spectrum disorder (ASD), but this study aimed to investigate if lower vitamin D levels actually precede ASD diagnoses.
  • A prospective cohort study was conducted with 3,852 preschool-aged children, utilizing blood samples to measure vitamin D levels and tracking autism diagnoses through medical records over an average follow-up of 2.5 years.
  • The results showed no significant association between vitamin D concentration or supplementation in early childhood and the incidence of ASD, suggesting that vitamin D may not play a crucial role in the development of autism.
