Cerebral Radiation-Induced Vasculopathy Mimicking Primary Central Nervous System Vasculitis.

Cranial irradiation is one of the main treatment modalities for tumors of the CNS. However, it can lead to significant damage to the treated region. Among the late complications of radiation therapy to the brain is vasculopathy of the small and/or large arteries.

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy: Atypical clinical presentation with isolated frontotemporal dementia.

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a hereditary syndrome caused by heterozygous mutations in the gene that manifests in adulthood and is characterized by recurrent transient ischemic attacks and strokes, migraine-like headaches, psychiatric disturbance, and progressive dementia. The current study reports an interesting case of CADASIL in a Saudi patient with a heterozygous mutation in exon 18 of the gene presenting only with cognitive decline without migraine or stroke. The diagnosis was suspected mainly because of the typical brain magnetic resonance imaging (MRI) features that led to performing genetic testing to confirm the diagnosis.

Acute Disseminated Encephalomyelitis Post COVID-19 Pneumonia.

Acute disseminated encephalomyelitis (ADEM) is a monophasic condition characterized by inflammation of the central nervous system. Besides multiple sclerosis, optic neuropathy, acute transverse myelitis, and neuromyelitis optica spectrum disorder, ADEM is a primary inflammatory demyelinating disorder of the central nervous system. It is estimated that approximately three-quarters of cases of encephalomyelitis occur after an infection or immunization, where the onset of neurological disease is coincident with a febrile event.

Temporal Muscle Cavernous Hemangioma: A Case Report and Literature Review.

Hemangiomas are nonmalignant vascular lesions commonly seen in both the skin and mucosa that rarely occur in skeletal muscles. According to the type of vessel, a hemangioma can be differentiated into capillary, cavernous, or mixed types. The following report describes a case of temporalis muscle hemangioma in a 45-year-old female who presented with painful swelling in the left outer orbital wall, which had been growing in size over the past 12 months.

Atypical Familial Amyotrophic Lateral Sclerosis Secondary to Superoxide Dismutase 1 Gene Mutation With Coexistent Axonal Polyneuropathy: A Challenging Diagnosis.

Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a neurodegenerative disease that involves both the upper and lower motor neurons. Familial ALS, including superoxide dismutase 1 (SOD1) mutation, accounts for 5-10% of all cases of ALS. Typically, the symptoms of ALS are purely motor, though coexistent sensory symptoms have been reported in rare cases.

Knowledge, attitude, and practices regarding dietary habits among medical and non-medical university students.

Background: Medical students even though being aware of the importance of well-balanced nutrition do tend to have laxity in practicing it themselves leading to poor nutrition. The aim of this study was to compare the awareness and knowledge of dietary habits among medical and non-medical students.

Methods: This cross-sectional study was carried out in two universities in the Jeddah province, King Saud bin Abdulaziz University for Health Sciences (KSAU-HS) and King Abdulaziz University (KAU), Jeddah over 6 months.

The influence and impact of smoking on red blood cell morphology and buccal microflora: A case-control study.

Background: Tobacco smoking is a major health issue worldwide. In addition to several health problems, smoking can also cause buccal cavity ulcers and buccal cavity cancer in case of chronic smoking. Tobacco smoking may also lead to deranged morphology of red blood cells (RBCs), which results in reduced oxygen carrying capacity of the blood.
