Objective The decision to perform medical or mechanical therapy in patients with aborted sudden cardiac death (ASCD) due to coronary spasm is controversial. The Japanese Circulation Society guidelines for the diagnosis and treatment of patients with coronary spastic angina mentioned that implantable cardioverter-defibrillator (ICD) is one option in patients with ASCD due to coronary spasm. We investigated the usefulness of spasm provocation tests under medications in five patients with ASCD due to coronary spasm. ⋯ An ICD was implanted in two patients, including one with refractory spasm and one with left main trunk spasm. One patient died due to pulseless electrical activity without ventricular fibrillation, while the remaining four patients survived. Conclusion Spasm provocation tests under medication in patients with ASCD due to coronary spasm may be an option when deciding on medical or mechanical therapy.

Case Reports
Gap-related Pulmonary Vein and Left Atrial Flutter Mimicking Cavotricuspid Isthmus-dependent Atrial Flutter.
We herein report a 79-year-old man with recurrent atrial flutter (AFL) following catheter ablation for pulmonary vein (PV) isolation and block line of the cavotricuspid isthmus. An electrophysiological study and three-dimensional mapping results revealed left atrium (LA)-PV macroreentrant flutter caused by a conduction gap, possibly correlated to prior application, which mimicked cavotricuspid isthmus-dependent AFL. This LA-PV flutter was terminated after applying radiofrequency to the gap at the antrum near the bottom left inferior PV in the posterior LA wall. During follow-up, the patient did not present with atrial tachyarrhythmias; antiarrhythmic drugs were therefore not administered.

We herein report a 66-year-old woman with advanced lung adenocarcinoma [programmed cell death and its ligand 1 (PD-L1) tumor proportion score 60%] lacking driver oncogenes in whom meningeal carcinomatosis, along with sudden onset dizziness, deafness, and consciousness disturbance, appeared after second-line chemotherapy. Whole-brain radiation therapy (WBRT) and Pembrolizumab were subsequently administered, and third-line chemotherapy with Pembrolizumab is now ongoing. At the time of writing, the patient has achieved a 23-month survival without disease progression. Our findings suggest that the combination of WBRT and an immune checkpoint inhibitor is effective for non-small-cell lung cancer patients lacking driver oncogenes who develop meningeal carcinomatosis.

Anti-myelin oligodendrocyte glycoprotein (MOG) antibodies have been associated with steroid-responsive cortical encephalitis and comorbid generalized epilepsy. A 44-year-old woman developed repeated epilepsia partialis continua (EPC) without generalized seizures and was anti-MOG antibody-positive. Radiological abnormalities were detected in the bilateral medial frontoparietal cortices, but there were no cerebrospinal fluid abnormalities. ⋯ However, encephalitis recurred four months later when pleocytosis appeared, and steroid therapy was effective. Altogether, EPC without typical cerebrospinal fluid features can be an early sign of anti-MOG antibody-positive encephalitis. Thus, patients with EPC of unknown etiology need to be screened for anti-MOG antibodies.

We herein report a rare case of cutaneous and lymph node metastases that recurred 12 years after radical total gastrectomy for stage IIA gastric cancer. A 62-year-old man had undergone total gastrectomy for stage IIA gastric cancer 12 years earlier without postoperative adjuvant chemotherapy. ⋯ The lymph node specimens and cutaneous biopsies indicated late recurrence of the gastric cancer. Concurrent chemoradiotherapy was administered effectively, but after eight months, the patient died due to deterioration in his general condition.
