Introduction: Intravenous thrombolysis within 4.5 hours from symptom onset improves functional outcome in acute ischemic stroke patients. Repeated intravenous tissue plasminogen activator (IVtPA) is contraindicated in patients presenting with early recurrent stroke (ERS) within 3 months from the initial stroke because of a greater risk of intracranial hemorrhage.
Case Presentation: A 59-year-old man presented with ERS, National Institute of Health Stroke Scale of 16, 10 days after a previous stroke. Brain computed tomography (CT) showed a previous hypodensity with 4 cm volume. Angio-CT highlighted the left middle cerebral artery and left internal carotid occlusion. Perfusion CT showed small deep core and large penumbra. The patient underwent IVtPA. After 24 hours, the National Institute of Health Stroke Scale was 7, and CT scan showed an acute ischemic lesion in the left basal ganglia area and frontal lobe without hemorrhagic transformation.
Conclusion: This case report suggests that further randomized studies may evaluate whether repeated IVtPA may be safe and effective in ERS occurring shortly after a previous stroke when patients experience a period of complete neurological regression, minor disability, and a small infarct volume. Should the hypothesis be confirmed, small volume core and wide volume penumbra at perfusion CT may support the decision of adopting IVtPA repetition.

Electrolyte imbalance management is crucial in diverse clinical scenarios, with intravenous potassium repletion often required. High-concentration infusions can pose severe complications if extravasation occurs, leading to phlebitis, local tissue damage, or in severe cases, cutaneous necrosis. This risk is elevated in geriatric patients due to factors like reduced tissue elasticity and sensitivity.

Primary Hypertrophic Osteoarthropathy (PHOAR1) is characterized by autosomal recessive loss of function variants in 15-hydroxyprostaglandin dehydrogenase (HPGD) leading to digital clubbing, periostosis, pachydermia, and severe hyperhidrosis. HPGD catalyzes the first step of prostaglandin E2 (PGE2) degradation. Selective COX-2 inhibitors have proved beneficial in adults, though it is unknown if early initiation of COX-2 inhibitors can alter the natural history of PHOAR1.

Objectives: Neonatal severe hyperparathyroidism (NSHPT) is a rare condition characterized by inactivating mutations in the calcium-sensing receptor () gene, leading to significant hypercalcemia and related complications.
Case Presentation: We present a case of a six-day-old male infant with weakness, jaundice, and hypotonia, later diagnosed with NSHPT due to a known homozygous mutation (c.242T>A; p.

A 61-year-old male presented with hematemesis and melena. Biopsy and immunohistochemistry confirmed mucosa-associated lymphoid tissue (MALT) lymphoma in the posterior wall of the gastric antrum, prompting further evaluation with F-fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT). In addition to elevated uptake in the gastric antrum, F-FDG PET/CT showed diffuse uptake in multiple bone marrow, initially suspected to indicate bone marrow involvement by lymphoma.
