We report a case with an isolated single coronary artery originating from the ascending aorta, which to our knowledge has never been described before. A 51-year-old man presented for evaluation of atypical chest pain, suffering from a short resting chest pain for 3 days. However, serial electrocardiogram showed no change during chest pain. Cardiac enzymes such as CK-MB, Troponin-I, and myoglobin were within normal limit. Aortography and coronary angiography revealed a single coronary artery originating from the postero-lateral wall of the ascending aorta above the left coronary siuns. However, this anomaly was not of clinical significance based on the atypical nature of the chest pain, negative exercise echocardiography and an absence of obstruction of the coronary artery.

Posterior reversible encephalopathy syndrome is a clinicoradiological syndrome characterized by a unique reversible pattern on imaging and total regression of clinical symptoms and signs. Hypertensive brainstem encephalopathy (HBE), a brainstem variant of posterior reversible encephalopathy syndrome, is rare. In addition, a concomitant occurrence of acute ischemic stroke and HBE is even more rare. We here report three patients with HBE accompanied by acute cerebral infarction detected by brain magnetic resonance imaging and the importance of initial blood pressure control.

A 48-year-old man came with a left-sided headache that was compatible with diagnostic criteria of cluster headache. Left oculomotor nerve palsy developed 2 weeks after headache onset. Magnetic resonance imaging showed wall thickening and enhancement by contrast material in the lateral aspect of the left cavernous sinus, consistent with a possible inflammatory lesion. The patient reported the almost complete remission of the pain and diplopia after steroid therapy. We speculate that Tolosa-Hunt syndrome should be included as a cause of cluster-like headaches.

Background:
The importance of establishing a regional stroke safety net for the treatment of acute stroke is increasingly emphasized. In this study, we analyzed effectiveness of transferring the suspected acute ischemic stroke (AIS) patients through the 1899-0215 hotline system from 119 ambulances and nearby hospitals.
Methods:
From July 2015 to July 2022, we analyzed data from 632 suspected acute stroke patients through the hotline. Furthermore, we investigated the proportion of patients in the target population who were eligible for reperfusion therapy and compared cases transferred by 119 emergency services (EMS) with those transferred from nearby hospitals.
Results:
Six hundred thirty-two suspected acute stroke patients were transferred to our stroke center through the 1899-0215 hotline system. The accuracy of diagnosing acute stroke among transferred patients is 81.0% for 119 EMS and 80.5% for cases transferred from nearby hospitals. Of the 200 patients transferred from hospitals, they were transferred from 47 nearby hospitals with an average transfer distance of 38.2 km and an average transfer time of 65 minutes. Among 291 patients diagnosed with AIS, The onset-to-door time was significantly shorter (p<0.01) for patients transferred by 119 EMS. The proportion of patients who received reperfusion therapy was significantly higher (p<0.01) for those transferred by 119 EMS.
Conclusions
The hotline service will become a useful tool for establishing a regional stroke network in the Busan area, and its effectiveness will be particularly useful for 119 EMS. Measures are needed in the Busan metropolitan region to ensure the speediness of transferring acute stroke patients between hospitals.

Acute encephalopathies can be defined as an acute central nervous system (CNS) insult, due to an underlying pathology. The clinical symptoms almost always include an acute state of confusion and cognitive impairment. Toxic encephalopathies can occur acutely or chronically depending on the toxic drugs and other substances as well as the individual metabolism of the drug. The organs acutely affected include the heart, lung and kidneys. However, the brain, spinal cord and sympathetic nerves can be affected chronically. If the toxic substance passes through the bloodbrain barrier into the hypothalamus and the posterior pituitary gland, the result can be diabetes insipidus. If the substance affects the anterior pituitary gland, the result can include hormone dysfunction, impaired immune function and altered cognition or personality. We report a patient that developed acute toxic encephalopathy after the prescribed dose of oxycodone was exceeded.

PURPOSE: The association between liver enzymes and death from external causes has not been examined. We investigated the association between serum aminotransferase levels and external-cause mortality in a large prospective cohort study. MATERIALS AND METHODS: A total of 142322 subjects of 35-59 years of age who completed baseline examinations in 1990 and 1992 were enrolled. Mortalities were identified using death certificates. Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were categorized into quintiles. Sub-distribution hazards ratios and 95% confidence intervals (CIs) were estimated using a competing risks regression model in which deaths from other causes were treated as competing risks. RESULTS: Of 8808 deaths, 1111 (12.6%) were due to external causes. Injury accounted for 256 deaths, and suicide accounted for 255. After adjusting for covariates, elevated ALT and AST were significantly associated with an increased risk of all external-cause mortalities, as well as suicide and injury. Sub-distribution hazards ratios (95% CIs) of the highest versus the lowest quintiles of serum ALT and AST were, respectively, 1.57 (1.26-1.95) and 1.45 (1.20-1.76) for all external causes, 2.73 (1.68-4.46) and 1.75 (1.15-2.66) for suicide, and 1.79 (1.10-2.90) and 1.85 (1.21-2.82) for injury. The risk of external-cause mortality was also significantly higher in the fourth quintile of ALT (21.6-27.5 IU/L) than in its first quintile. CONCLUSION: Elevated aminotransferase levels, even within the normal range, were significantly associated with increased risk of all external-cause mortalities, including suicide, and injury.

BACKGROUND: With mitral valvular heart disease, chronic atrial fibrillation(AF) is not likely to return to sinus rhythm after the operation. We evaluate the long term results and factors in recurrence of AF after modified Maze operation with mitral valve surgery. MATERIAL AND METHOD: From 1990 to 1996, 35 patients with chronic AF underwent modified Maze operation with mitral valve procedure in patients with chronic AF. The mean duration of AF was 7.7 +/-4.5 years. The concomitant operations were 34 mitral valve replacement(with 4 tricuspid annuloplasty and 3 tricuspid valve replacement)and 1 mitral valve repair. We analyzed the long term results and factors in recurrence of AF. RESULT: At immediate postoperatively, 33 of the 35 patients(93.9%) were converted to sinus rhythm. There was one operative death. However, AF recurred in 12 out of 35 patients during hospitalization and AF in these 12 patients were treated with antiarrhythmic drugs and electrical defibrillation 2-3 months later. Two out of twelve patients were failed in conversion to sinus rhythm after cessation of medication with side effects. During follow-up(71.1 +/-17.5 months, range 3-9 years), AF recurred in 9 patients and overall conversion rate to sinus rhythm was 73.5%. Predictors of postoperative AF included: duration of preoperative AF(maintenance group: recurrence group=6.3 years VS. 10.3 years, p=0.008) and cardiothoracic ratio on preoperative chest X-ray(0.58 VS. 0.72, p=0.009). CONCLUSION: AF surgery with mitral valve procedure increase the chance of recovery into sinus rhythm, reduce the incidence of atrial arrhythmia, and reduce the left atrial size with decreasing wall stress simultaneously. In order to decrease the incidence of postoperative arrhythmia, proper modification of the surgery with medical therapy should be considered.

PURPOSE: Although inconsistent, reports have shown fibrinogen levels to be associated with atherosclerosis. Accordingly, since cigarette smoking is associated with increased levels of fibrinogen and atherosclerosis, it may also affect the association between fibrinogen and atherosclerosis. We investigated the associations between fibrinogen and carotid intima-media thickness (IMT) according to smoking status in a Korean male population. MATERIALS AND METHODS: Plasma fibrinogen levels were measured in 277 men aged 40-87 years without a history of myocardial infarction or stroke. High-resolution B-mode ultrasonography was used to examine the common carotid arteries. IMT level was analyzed both as a continuous (IMT-max, maximum value; IMT-tpm, 3-point mean value) and categorical variable (higher IMT; presence of plaque). Serial linear and logistic regression models were employed to examine the association between fibrinogen and IMT according to smoking status. RESULTS: Fibrinogen levels were positively associated with IMT-max (standardized beta=0.25, p=0.021) and IMT-tpm (standardized beta=0.21, p=0.038), even after adjusting for age, body mass index, systolic blood pressure, fasting glucose, and total cholesterol to high-density lipoprotein cholesterol ratio in current smokers (n=75). No significant association between fibrinogen and IMT, however, was noted in former smokers (n=80) or nonsmokers (n=122). Adjusted odds ratios (95% confidence interval) for having plaque per one standard deviation higher fibrinogen level were 2.06 (1.09-3.89) for current smokers, 0.68 (0.43-1.10) for former smokers, and 1.06 (0.60-1.87) for nonsmokers. CONCLUSION: Our findings suggest that cigarette smoking may modify the association between fibrinogen and carotid atherosclerosis. Further studies are required to confirm this finding in different populations.
