Massive Presentation of a Neglected Basal Cell Ulcer on the Forehead and Outcome With Radiation Therapy: A Case Report and Literature Review.

Basal cell carcinoma (BCC) of the scalp is the most common cancer of the skin and is locally invasive. The patched/hedgehog intracellular signaling pathway is responsible for regulating cell growth and tumor formation by inactivating mutation of protein patched homolog 1 (PTCH1) or activating mutation of Smoothened (SMOm). BCC can cause significant morbidity from local destruction if neglected.

COVID-19-associated familial acute disseminated encephalomyelitis (ADEM): A case report.

Background: Several neurological complications are being reported in hospitalized patients with severe COVID-19 infection. This is presumed due to direct spread of infection or due to immunological response. Acute disseminated encephalomyelitis (ADEM) is a rare inflammatory and demyelinating disorder of the central nervous system that is often preceded by infection or vaccination.

Cerebral Cavernous Malformations, Developmental Venous Anomaly, and Its Coexistence: A Review.

Background: Cerebral cavernous malformations (CCMs) are intracranial vascular malformations that can exist as a single lesion or mixed vascular lesions. The most common mixed form is the coexistence of CCM with an associated developmental venous anomaly (DVA). In this paper, we aim to give a comprehensive review of CCM, DVA, and their coexistence as mixed lesions.

Glucose-Regulated Protein 78 Autoantibodies Are Associated with Carotid Atherosclerosis in Chronic Obstructive Pulmonary Disease Patients.

Atherosclerosis prevalence is increased in chronic obstructive pulmonary disease (COPD) patients, independent of other risk factors. The etiology of the excess vascular disease in COPD is unknown, although it is presumably related to an underlying (if cryptic) systemic immune response. Autoantibodies with specificity for glucose-regulated protein 78 (GRP78), a multifunctional component of the unfolded protein response, are common in COPD patients and linked to comorbidities of this lung disease.

Perforated Jejunal Diverticulitis.

Small intestinal diverticula are very rare; their incidence ranges from 0.06 to 1.3%, with a higher prevalence after the 6th decade of life.
