[A Case of CA19-9-Producing Gastric Cancer with Recurrence of Lymph Node Metastasis That Achieved Clinical CR in Fourth-Line CapeOX Therapy].

A 74-year-old man underwent a distal gastrectomy for advanced gastric cancer. After surgical treatment, lymph node metastasis was observed during postoperative adjuvant S-1 chemotherapy. Weekly PTX plus RAM as second-line therapy and nivolumab as third-line therapy was administered, but lymph node enlarged and CA19-9 remained high.

Flow alteration therapy for impending rupture of intracranial giant aneurysm after flow diverter placement.

Background: Flow diverter (FD) placement is generally effective for intractable internal carotid artery (ICA) aneurysms. However, salvage treatment for the aneurysm enlarging even after FD placement remains to be elucidated. Additional overlapping FD placement is considered the first-line treatment for residual or recurrent aneurysms.

Impact of subcallosal artery origin and A1 asymmetry on surgical outcomes of anterior communicating artery aneurysms.

Background: Surgical clipping of anterior communicating artery (ACoA) aneurysms remains challenging due to their complex anatomy. Anatomical risk factors for ACoA aneurysm surgery require further elucidation. The aim of this study is to investigate whether proximity of the midline perforating artery, subcallosal artery (SubCA), and associated anomaly of the ACoA complex affect functional outcomes of ACoA aneurysm surgery.

The Cervical Spine as a Predominant Site of Cerebrospinal Fluid Leak: Preliminary Results Using the Overflow Leak Test.

Background: Cerebrospinal fluid (CSF) hypovolemia is usually treated via an epidural blood patch (EBP). Accurate placement of the EBP at the site of CSF leakage is required for successful treatment of CSF hypovolemia. The thoracolumbar spine is evidently a common site of leakage, but because rates of detection of the leakage site via conventional imaging have historically not been high, there may be other common leakage sites.

[Preliminary Experience of a Biplane Flat Panel and Tailor-made Operating Table-equipped Hybrid Operating Room].

A hybrid operating room(Hybrid OR), where operative equipment and flat panel angiography are both available, is becoming common for complex cerebrovascular surgery. However, the current Hybrid OR remains suboptimal as it is not cost-effective and contains uncomfortable operating beds, and a single-plane flat panel. Therefore, we introduced a novel Hybrid OR system, which has a biplane flat panel detector and three mutually exchangeable tailor-made operating beds.

Correction to: Risk of gastric cancer in the second decade of follow-up after Helicobacter pylori eradication.

In the original publication of the article, the figure 3 was published with errors. The corrected figure 3 should appear as in this correction.

Risk of gastric cancer in the second decade of follow-up after Helicobacter pylori eradication.

Background And Aims: Eradication of Helicobacter pylori reduces the risk of gastric cancer. In this study, we investigated the risk beyond 10 years after eradication of H. pylori.

[Failed Surgical Clipping of a Posterior Communicating Artery Aneurysm with Oculomotor Nerve Palsy due to Ventricular Tachycardia:Validity of Endovascular Coiling in the Hybrid Operating Room].

Unruptured posterior communicating artery aneurysms with oculomotor nerve palsy are at high risk of rupture, and early intervention is recommended to prevent aneurysm bleeding and to improve oculomotor function. Both surgical clipping and endovascular coiling are available, and either of them is applied according to the anatomical condition and patient's comorbidity. In this article, we describe a case of an unruptured posterior communicating artery aneurysm with oculomotor nerve palsy, which was initially treated with surgical clipping.

Impact of temperature decline from the previous day as a trigger of spontaneous subarachnoid hemorrhage: case-crossover study of prefectural stroke database.

Objective: Several environmental factors have been reported to correlate with incidence of spontaneous subarachnoid hemorrhage (SAH). However, because of different patient selection and study designs among these studies, meteorological factors that trigger the incidence of SAH in a short hazard period remain unknown. Among meteorological factors, daily temperature changes may disrupt and violate homeostasis and predispose to cerebrovascular circulatory disturbances and strokes.

Surgical case of intracranial osteoma arising from the falx.

Intracranial osteomas completely unrelated to osseous tissues are extremely rare. In the present study, the case of a 40-year-old female who presented with persistent headache is reported. Computed tomography (CT) and bone window CT revealed an ossified lesion in the frontal area.

Seventeen-year effects of eradicating Helicobacter pylori on the prevention of gastric cancer in patients with peptic ulcer; a prospective cohort study.

Background: We previously reported that eradication of Helicobacter pylori in our cohort of patients with peptic ulcer disease reduced their risk of developing gastric cancer to approximately one-third after a mean follow-up period of 3.4 years (up to 8.6 years).
