As cases of magnesium oxide pill aspiration are rare, the associated airway proinflammatory properties and appropriate analytic strategies remain unclear. An 81-year-old woman presenting with dyspnea was diagnosed with magnesium oxide pill aspiration. Computed tomography, a "mixing test" with levodopa, and a magnesium content analysis revealed a similar density between the foreign body and her prescribed magnesium oxide pill.

Article Synopsis
  • Spontaneous hemostasis in adrenal injuries is common due to Gerota's fascia, leading to conservative treatment without major complications in most cases.
  • An 85-year-old man experienced a right adrenal injury and stable vital signs after blunt trauma but developed severe abdominal pain and hypotension 20 days later due to a delayed adrenal rupture.
  • This case highlights that delayed adrenal rupture is extremely rare and emphasizes the importance of timely diagnosis and treatment to prevent serious outcomes.

We retrospectively evaluated the safety and effectiveness of an external carotid arterial sheath (ECAS) for intra-arterial chemotherapy (IACT) for locally advanced tongue cancer. Thirty-one patients with the Union for International Cancer Control's 8th TNM stage III-IV tongue cancer underwent IACT using the ECAS combined with RT and systemic chemotherapy with either cisplatin and fluorouracil (FP) or docetaxel, cisplatin, and fluorouracil (TPF) between October 2015 and February 2021. The ECAS was inserted retrogradely via the superficial temporal artery, and the tip was placed in the external carotid artery between the maxillary and facial arteries.

Massive hemoptysis may originate from injured pulmonary arteries, such as from pulmonary artery pseudoaneurysms (PAPs). A 93-year-old man, diagnosed with pneumonia, was hospitalized; he later developed a lung abscess (controlled with intravenous antibiotics). On post-hospitalization day 29, he suddenly developed hemoptysis.

It remains unknown which surrogate markers can predict diagnostic test results for primary hyperaldosteronism (PA). The Secondary Hypertension Registry Investigation in Mie Prefecture (SHRIMP) study has sequentially and prospectively recruited 128 patients with hypertension with an aldosterone-to-renin ratio (ARR) greater than 20, evaluated the differences among essential hypertension (EHT), idiopathic hyperaldosteronism (IHA), and aldosterone-producing adenoma (APA), and analyzed the predictors for the confirmatory tests. The patients underwent saline-loading, captopril-challenge, and upright furosemide-loading tests.

Article Synopsis
  • This study assessed the safety and effectiveness of radiofrequency ablation with a multiple-electrode system in patients with malignant bone tumors larger than 3 cm.
  • Out of 20 patients, 95% experienced no adverse effects, while most reported significant pain relief, and 88.9% showed positive tumor response on follow-up imaging.
  • The procedure demonstrated a 1-year survival rate of 60.9%, indicating that RF ablation is a safe option for managing large bone tumors.

Purpose: The purpose of this study was to evaluate the efficacy of portal venous (PV) stent placement and find groups who benefit from this procedure among patients with symptomatic PV hypertension caused by malignant tumors.

Materials And Methods: From October 2001 to January 2013, 13 patients underwent PV stent placement because of PV stenosis or occlusion caused by bile duct cancer (n = 7), pancreatic cancer (n = 5), or nodal metastasis (n = 1). Technical success, changes in PV pressure gradient and palliative prognostic index (PPI) scores before and after stent placement, clinical outcomes, and complications were evaluated.

The aim of this study was to elucidate the importance of three tumor markers, alpha-fetoprotein (AFP), Lens culinaris agglutinin A-reactive fraction of AFP (AFP-L3), and des-gamma-carboxy prothrombin (DCP), for detecting and predicting the recurrence of hepatocellular carcinomas (HCCs). A total of 108 patients with initial non-advanced HCC who underwent curative radiofrequency ablation (RFA) in our hospital were enrolled in this study. The effectiveness of the three tumor markers for detecting recurrence and recurrence-free survival was analyzed.
