Various anomalous origins of the vertebral arteries (VAs) have been reported. However, anomalous origins of the bilateral VAs arising directly from the aortic arch are extremely rare. We encountered a 60-year-old male who developed sudden-onset right hemiparesis with an incidentally discovered rare origins of the bilateral VAs from aortic arch. CT angiography demonstrated the right VA originating from the aortic arch distal to the left subclavian artery and left VA originating from the aortic arch between the left common carotid artery and the left subclavian artery. The possible embryological mechanism of this variant was also reviewed. If the VA can not be found in the usual position during the procedure, a rare variant of the VA with anomalous origin should be considered. Understanding these variations is important to avoid unexpected events during endovascular procedures or surgery.

A 40-year-old female visited our clinic for visual disturbance of the right eye, in which a few creamy-yellow retinal lesions and visual field constrictions were noted. She had been treated for primary CNS lymphoma and was in complete remission. After failure to follow-up for three months, she lost vision in the right eye, at which time active panuveitis was seen. Decreased vision and field constriction was observed in the left eye. Her left eye showed a granular pattern and dye leakage from the vessels and disc on fluorescein angiography and small RPE humps were seen in optical coherence tomography (OCT). Diffuse large malignant B-cells with strong immunoreactivities with CD20 immunostaining were seen in the epiretinal membrane biopsy specimen. Intravitreal injections of methotrexate (MTX) (800 microgram/0.1 ml in the right eye, 400 microgram/0.05 ml in the left eye) were performed twice weekly for one month, once weekly for the following month, once every two weeks for the next month, followed by nine monthly injections. Both eyes were free from malignant cells on vitreous biopsy six months later. There was no leakage seen by angiography, but the granular pattern persisted. Visual field constriction was slightly improved, and the small RPE humpsdetachments seen in OCT disappeared. EOG Arden ratio was decreased in both eyes, and b wave amplitude of scotopic ERG was decreased in the left eye. She was free from recurrence until six months later. No ocular complications except minimal opacity of the crystalline lenses were noted in both eyes.

Osteoporotic vertebral compression fractures have become common in aging societies and can lead to a decreased quality of life with severe back pain and neurological deficits.Traditional direct decompression and stabilization surgeries can produce sufficient decompression and provide good results. However, after surgical treatment, some elderly patients with numerous chronic diseases often experience severe postoperative complications owing to the long surgery duration and massive bleeding. Therefore, to prevent perioperative morbidity, other surgical methods that simplify the surgical process and reduce the operation time are required. Herein, we describe a case of indirect decompression using ligamentotaxis and sequential anabolic agents. To examine their effectiveness during surgery, we monitored intraoperative motor-evoked potentials. The patient’s neurological symptoms improved postoperatively. After the operation, the anabolic agent “romosozumab” was injected monthly to treat osteoporosis, prevent additional fractures, and accelerate posterolateral fusion. On serial follow-up, the anterior body height of the fractured vertebra improved significantly, demonstrating the importance of osteoporosis treatment using anabolic agents.Indirect decompression surgery may have early effects, whereas sequential anabolic agent use may consolidate the long-term effects of surgical treatment.

Dapagliflozin is a recently developed oral anti-diabetic drug and SGLT2 inhibitor with well-known cardioprotective and renoprotective effects. Although a reduction of the glomerular filtration rate is induced by volume depletion and tubule-glomerular feedback during the early period after administering a SGLT2 inhibitor, the renal prognosis improves more with a decrease of proteinuria. However, the risk of acute kidney injury increases in heart failure and hypovolemia patients, and in those taking certain drugs, such as non-steroidal anti-inflammatory drugs, angiotensin-converting enzyme inhibitor/angiotensin II receptor blockers, or diuretics. We report acute kidney injury after dapagliflozin administration in a diabetic patient with acute cerebral infarction accompanied by right hemiplegia, motor aphasia, and dysphagia.

Background/Aims: The SAMe-TT2R2 score is used for assessing anticoagulation control (AC) quality with warfarin. However, it is hard to apply SAMe-TT2R2 score in Asian patients with atrial fibrillation (AF), because it has not been proven in those populations. This study aimed to validate the SAMe-TT2R2 score in Asian patients with AF and suggest a modified SAMe- TT2R2 score for this population. Methods: We analyzed 710 Korean patients with AF who were using warfarin. The AC quality was assessed as the mean time in therapeutic range (TTR). Each component of SAMe-TT2R2 score was evaluated for the relationship with AC. Further clinical factors that predict AC were analyzed. Identified factors were re-assorted and constructed as SA2Me-TTR scoring system. Results: Of the components of the SAMe-TT2R2 score, female, age, and rhythm control were associated with AC. Heart failure and renal insufficiency were newly identified factors associated with AC. The modified SA2Me-TTR score was reconstructed with the relevant risk factors (S, female gender, 1 point; A, age < 60 yr, 2 points; Me, medical history of heart failure, 1 point; T, treatment for rhythm control, 1 point; T, history of stroke or transient ischemic attack, 1 point; R, renal insufficiency, 1 point). The modified SA2Me-TTR score demonstrated an excellent relationship with the grading of AC. The modified SA2Me-TTR score ≤ 1 identified patients with good AC (hazard ratio 2.46, 95% CI 1.75–3.47). Conclusions The modified SA2Me-TTR score was useful for guiding oral anticoagulants selection in Asian patients with AF.

This study aimed to investigate the status of primary liver cancers found through a routine health check-up. The data of subjects who were diagnosed with primary liver cancer for the first time through a routine health check-up during a period of 8-yr were analyzed. Primary liver cancers were detected for the first time in 34 subjects among 91,219 routine health check-up subjects. Only 11.8% of primary liver cancer subjects had been under previous surveillance. Of them, 55.8% were positive for HBsAg, 17.7% were positive for anti-HCV, and 8.8% were heavy alcohol comsumers. However, 17.7% of the subjects were neither heavy alcohol consumers nor positive for both HBsAg and anti-HCV. Of the subjects, 50.0% had a single nodular tumor, 23.5% had multi-nodular tumors, and 26.5% had an infiltrative tumor. A routine health check-up may provide beneficial opportunities to detect a liver cancer in a very early stage. It is beneficial to start surveillance in high-risk subjects for liver cancer or to detect any liver cancer in subjects without risk factors of chronic viral hepatitis or heavy alcohol consumption.
