Inappropriate administration of thrombolytic agents to acute type A aortic dissection patients with acute myocardial infarction could result in catastrophic outcomes. A 38-year-old female patient without any previous cardiac history visited the emergency room due to a severe acute onset of retrosternal chest pain. The ECG showed a complete heart block with a junctional escape rhythm at 33 beats/min and more than 2 mm of ST elevation in the inferior and anterior precordial leads. Because of an acute myocardial infarction, prompt thrombolytic agent (tPA) was administered. The patient had cardiogenic shock and persistent chest pain after the thrombolytic therapy. We performed the transthoracic echocardiography (TTE). The TTE showed a dissection flap just above the aortic valve and akinesia of the inferior wall of the left ventricle. She underwent an emergency surgical correction. However, the patient died due to the failure of weaning from the cardiopulmonary bypass machine.

3.Surgical Treatment of Chronic Lateral Ankle Instability: Repair versus Reconstruction
Journal of Korean Foot and Ankle Society 2019;23(1):1-5
Surgical treatment to restore stability in the ankle and hindfoot and prevent further degenerative changes may be necessary in cases in which conservative treatment has failed. Anatomical direct repair using native ligament remnants with or without reinforcement of the inferior retinaculum is the so-called gold standard operative strategy for the treatment of lateral ankle instability. Non-anatomical lateral ligament reconstruction typically involves the use of the adjacent peroneus brevis tendon and applies only those with poor-quality ligaments. On the other hand, anatomic reconstruction and anatomic repair provide better functional outcomes after the surgical treatment of chronic ankle instability patients compared to a non-anatomic reconstruction. Anatomical reconstruction using an autograft or allograft applies to patients with insufficient ligament remnants to fashion direct repair, failed previous lateral ankle repair, high body mass index, or generalized ligamentous laxity. These procedures can provide good-to-excellent short-term outcomes. Arthroscopic ligament repair is becoming increasingly popular because it is minimally invasive. Good-to-excellent clinical outcomes have been reported after short and long-term follow-up, despite the relatively large number of complications, including nerve damage, reported following the procedure. Therefore, further investigation will be needed before widespread adoption is advocated.

BACKGROUND AND OBJECTIVE: Mitral annulus velocity measured by doppler tissue imaging (DTI) has been used as a method of evaluation of the left ventricular diastolic function. This study was aimed to evaluate the left ventricular diastolic function using the mitral annulus velocity measured by DTI in the patients with hypertension. METHODS AND SUBJECTS: One hundered twenty nine patients with blood pressure above 140/90mmHg and age sex matched 123 normotensive subjects were studied. For measuring the mitral annulus velocities by DTI, we used the 2.5 MHz probe (Sequoia, Accuson) in apical four chamber view with the sample volume at the septal portion of the mitral annulus. RESULTS: Mitral annular velocities were easily obtained from all subjects. In the hypertension group, mitral annulus E'velocity was significantly lower than normotensive controls (5.4 1.3 cm/sec vs 6.5 1.8 cm/sec, p<0.001) and mitral annulus A' velocity was significantly higher than normotensive controls (8.6 1.4 cm/sec vs 7.9 1.1 cm/sec, p<0.001). In comparison with patients with normal LVML(IV mass index in hypertension group and subjects with normal LVMI in normotensive controls, mitral annulus E'velocity was reduced in patients with normal LVMI in hypertension group compared with subjects with normal LVMI in normotensive controls (5.6 1.4 cm/sec vs 6.7 1.8 cm/sec, p<0.001). CONCLUSION: Mitral annulus velocity measured by DTI could be used as one of the parameters in evaluating the early changes of left ventricular diastolic function in the patient with hypertension.

We experienced one case of pulmonary lymphangioleiomyomatosis in 26-year-old female patient. She had taken antituberculous medication under the impression of miliary tuberculosis on simple chest X-ray at peripartum period. On outpatient follow-up she complained of progressive exertional dyspnea in spite of medication. Through careful history taking and physical examination, high resolutional CT, and open lung biopsy she was diagnosed as pulmonary lymphangioleiomyomatosis combined with incomplete type of tuberous sclerosis. So, we presented the case with the brief review the literatures.

OBJECTIVE: The aim of this study is to investigate abnormal findings of social brain network in Korean children with autism spectrum disorder (ASD) compared with typically developing children (TDC). METHODS: Functional magnetic resonance imaging (fMRI) was performed to examine brain activations during the processing of emotional faces (happy, fearful, and neutral) in 17 children with ASD, 24 TDC. RESULTS: When emotional face stimuli were given to children with ASD, various areas of the social brain relevant to social cognition showed reduced activation. Specifically, ASD children exhibited less activation in the right amygdala (AMY), right superior temporal sulcus (STS) and right inferior frontal gyrus (IFG) than TDC group when fearful faces were shown. Activation of left insular cortex and right IFG in response to happy faces was less in the ASD group. Similar findings were also found in left superior insular gyrus and right insula in case of neutral stimulation. CONCLUSION: These findings suggest that children with ASD have different processing of social and emotional experience at the neural level. In other words, the deficit of social cognition in ASD could be explained by the deterioration of the capacity for visual analysis of emotional faces, the subsequent inner imitation through mirror neuron system (MNS), and the ability to transmit it to the limbic system and to process the transmitted emotion.

OBJECTIVE: To investigate the effect of laryngopharyngeal neuromuscular electrical stimulation (NMES) on dysphonia in patients with dysphagia caused by stroke or traumatic brain injury (TBI). METHODS: Eighteen patients participated in this study. The subjects were divided into NMES (n=12) and conventional swallowing training only (CST, n=6) groups. The NMES group received NMES combined with CST for 2 weeks, followed by CST without NMES for the next 2 weeks. The CST group received only CST for 4 weeks. All of the patients were evaluated before and at 2 and 4 weeks into the study. The outcome measurements included perceptual, acoustic and aerodynamic analyses. The correlation between dysphonia and swallowing function was also investigated. RESULTS: There were significant differences in the GRBAS (grade, roughness, breathiness, asthenia and strain scale) total score and sound pressure level (SPL) between the two groups over time. The NMES relative to the CST group showed significant improvements in total GRBAS score and SPL at 2 weeks, though no inter-group differences were evident at 4 weeks. The improvement of the total GRBAS scores at 2 weeks was positively correlated with the improved pharyngeal phase scores on the functional dysphagia scale at 2 weeks. CONCLUSION: The results demonstrate that laryngopharyngeal NMES in post-stroke or TBI patients with dysphonia can have promising effects on phonation. Therefore, laryngopharyngeal NMES may be considered as an additional treatment option for dysphonia accompanied by dysphagia after stroke or TBI.

For treatment of the pressure sore, variable methods have been developed such as skin graft, local flap, myocutaneous or fasciocutaneous flap. The myocutaneous flap has been used commonly for the coverage and padding of the wound. However, sacrifice of the deep muscles causes some problems such as intraoperative bleeding, functional disabilities of donor sites, and difficulty in controling the volume of the flap for the skin reability of myocutaneous flaps. To overcome these disadvantages, we tried perforator-based myocutaeous island flaps for reconstruction of buttock area. During the dissection of the flap, we could control the volume and shape of the flap exactly depending on the perforator. And minimal morbidity of the donor site is expected because of significant volume of gluteus maximus muscle need not be sacrificed. The perforator-based flaps are especially indicated for ambulatory patients, and for paraplegic patients as well. Clinically, total of 20 cases were treated with 13 parasacral perforator-based myocutaneous island flaps and 7 parasacral perforator-based fasciocutaeous island flaps. The mean operating time was 84 minutes, and the mean flap size was 8x9.2 cm. In donor sites, primary closure were done in all cases, post operative complications were wound dishescence in 1 case, venous congestion in 3 cases, but immediately improved. Recurrence was not reported.

OBJECTIVE: To investigate the association of family history of stroke with functional outcomes in stroke patients in Korea. METHODS: A case-control study was conducted. A total of 170 patients who were admitted to a rehabilitation unit were included. Risk factors for stroke such as age, sex, diabetes mellitus, hypertension, atrial fibrillation, smoking, high blood cholesterol and homocysteine level, obesity, and family history of stroke were taken into account. Stroke subtypes were the following: large vessel infarct, small vessel infarct, embolic infarct, subarachnoid hemorrhage, and intracranial hemorrhage. Stroke severity as assessed with the National Institutes of Health Stroke Scale (NIHSS), functional outcomes using the Korean version of the Modified Barthel index (K-MBI), Functional Independence Measurement (FIM), and cognitive function using the Korean version of Mini-Mental State Examination (K-MMSE) were assessed at admission and discharge. RESULTS: Subjects with a family history of stroke were more likely to have an ischemic stroke (90.7%) than were those without a family history (70.9%). The K-MBI, FIM, NIHSS, and K-MMSE scores did not show significant differences between patients with or without family history. CONCLUSION: Family history of stroke was significantly associated with ischemic stroke, but not with functional outcomes. Other prognostic factors of stroke were not distributed differently between patients included in this study with or without a family history of stroke.

OBJECTIVES: Streptococcus mutans (S. mutans) is the major causative bacteria in dental caries. Xylitol is an effective anticarious natural sugar substitute by inhibiting the virulence of S. mutans. However, long-term xylitol consumption leads to the emergence of the xylitol-resistant S. mutans (XR). The aim of this study is to analyze the difference of gene expression profile of xylitol-sensitive S. mutans (XS) and XR in 0.5% glucose containing TYE media, using a DNA chip. METHODS: S. mutans KCTC3065 was maintained in 0.5% glucose and 1% xylitol containing TYE media, during 30 days at 37degrees C 10% CO2 to form XR. The same procedures without xylitol were repeated for the formation of XS. Both XS and XR were cultured in 0.5% glucose with or without 1% xylitol containing TYE media overnight and total RNA was extracted. RNA from XS was labeled with Cy-3 dye as control, and XR were labeled with Cy-5 as references. DNA chip was hybridized for 18-20 h at 42degrees C. RESULTS: A total of 277 genes of DNA chip data were significantly increased or decreased in XR. There is a total of 174 XR up-regulated genes in 0.5% glucose and 1% xylitol containing TYE media, and a total of 103 down-regulated genes. For compare with results of DNA chip, 11 in up-regulated genes and 10 in down-regulated were verified by RT-PCR. The most abundant increased genes in XR were related to cell envelope, cellular processes, DNA metabolism, transcription, and protein folding and stabilization. The decreased genes in XR were related to amino acid biosynthesis, toxin production and resistance, energy metabolism, ribosomal proteins synthesis, and signal transduction. CONCLUSIONS: These results indicate that the difference of gene expression profile of XS and XR may be in existence. In particular, results of this study for XR up-regulated genes have a lot of similarities with the already published xylitol-related researches and other functional studies.
