Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) is a rare primary headache disorder characterized by severe intractable stabbing headache and accompanying tearing and conjunctival injections. In this report, we present a case of a patient with SUNCT who achieved sustained remarkable improvement more than 6 months following successful treatment with a single session of botulinum toxin A, after being refractory or intolerant to several preventives for 4 months.

Purpose: To compare the structural features of the optic nerve head (ONH) in moderate glaucoma patients with single-hemispheric and bi-hemispheric visual field (VF) defects. Methods: Patients with open-angle glaucoma (OAG) and a VF mean deviation between -6 and -12 dB were retrospectively enrolled. Based on VF defect patterns, eyes were classified into two groups: those with single-hemispheric VF defects and those with bi-hemispheric VF defects. Structural features analyzed included Bruch’s membrane opening area, lamina cribrosa (LC) thickness, temporal β-zone parapapillary atrophy with and without Bruch's membrane (βPPA+BM, βPPA-BM, respectively), and peripapillary retinal nerve fiber layer thickness using spectral-domain optical coherence tomography. Results: Out of 137 eyes from 124 patients, 80 eyes had single-hemispheric VF defects and 57 eyes had bi-hemispheric VF defects. The bi-hemispheric group exhibited longer axial length (p = 0.038), thinner central corneal thickness (p = 0.003), thinner LC (p < 0.001), and larger temporal βPPA+BM (p = 0.002) compared to the single-hemispheric group. Conclusions Among Korean OAG patients with moderate VF defects, those with bi-hemispheric VF defects showed more structurally vulnerable optic discs characterized by longer axial lengths, thinner central corneal thickness, thinner LC, and larger β PPA+BM compared to those with single-hemispheric VF defects. These findings underline the importance of evaluating ONH structures in monitoring glaucoma progression particularly in patients with extensive VF damage.

Gastric cancer is one of the most common cancers in Korea and the world. Since 2004, this is the 4th gastric cancer guideline published in Korea which is the revised version of previous evidence-based approach in 2018. Current guideline is a collaborative work of the interdisciplinary working group including experts in the field of gastric surgery, gastroenterology, endoscopy, medical oncology, abdominal radiology, pathology, nuclear medicine, radiation oncology and guideline development methodology. Total of 33 key questions were updated or proposed after a collaborative review by the working group and 40 statements were developed according to the systematic review using the MEDLINE, Embase, Cochrane Library and KoreaMed database. The level of evidence and the grading of recommendations were categorized according to the Grading of Recommendations, Assessment, Development and Evaluation proposition. Evidence level, benefit, harm, and clinical applicability was considered as the significant factors for recommendation. The working group reviewed recommendations and discussed for consensus. In the earlier part, general consideration discusses screening, diagnosis and staging of endoscopy, pathology, radiology, and nuclear medicine. Flowchart is depicted with statements which is supported by meta-analysis and references. Since clinical trial and systematic review was not suitable for postoperative oncologic and nutritional follow-up, working group agreed to conduct a nationwide survey investigating the clinical practice of all tertiary or general hospitals in Korea. The purpose of this survey was to provide baseline information on follow up. Herein we present a multidisciplinary-evidence based gastric cancer guideline.
