There have been many reports regarding complications associated with cardiopulmonary resuscitation(CPR) and it may be true that there are many unrevealed complications. Although it is used to say that 'any CPR is better than no CPR', inadvertent or inadequate CPR may insult in serious organ injury. This report describes a 64-year-old woman who suffered Mallory-Weiss tear resulting from inadvertent cardiopulmonary resuscitation by a bystander who had never been trained. Possible mechanisms of gastric injuries caused by CPR are suggested, and importance of adequate CPR training are emphasized in this report.

Renal dysplasia results from aberrant histogenesis in metanephric differentiation. It is characterized morphologically by abnormal organization and a persistence of primitive structures, such as cartilage, undifferentiated mesenchyme, and immature tubules. Six cases of renal dysplasia from five children and one adult are reviewed. Five patients were female and one patient was male. The chief complaint was urinary incontinence in four patients, dysuria in one patient, and the sixth patient suffered from vesicoureteral reflux. No evidence of family history of renal dysplasia in any patient was seen. According to Risdon's classification, three cases were hypoplastic dysplasia, one case was dysplasia in a duplex system, one case was dysplasia in a triplex system, and one case was dysplasia with vesicoureteral reflux. The ipsilateral ectopic ureteral orifice was identified in four patients, two of which drained into a Gartner's duct cyst, and the orifice was suggested in one patient. On histologic examination, all cases showed primitive ducts surrounded by concentrically arranged primitive mesenchyme. Nests of metaplastic cartilage were observed within the stroma in three of the six cases.

Synchronous neoplams are uncommon condition but the incidence is now being increased. The situation is rare when these tumors comes from different origin. We experienced the case with synchronous sigmoid colon cancer and anal squamous cell carcinoma with rectal mucosal metastasis. The patient was 61 years old male. He complained of intermittent hematochezia since 3~4 months ago. The patient underwent anterior resection for colon cancer and wide excision for anal squamous cell carcinoma. After surgical operation, postoperative adjuvant chemotherapy (5-FU + Leucovorin) and radiotherapy were done. In this case, we could preserve the anal sphincter using combined therapy. We think that this type of management may be useful treatment in patients with colon cancer and anal squamous cell cancer simultaneously.

The most frequently reported neurological complication of a wasp sting is ischemic stroke. We treated a patient with wasp sting with unusual complications. A 52-year-old man was hospitalized for anaphylactic shock after multiple wasp stings. Although the patient recovered consciousness after 2 days, he had global aphasia and right hemiparesis. Brain magnetic resonance imaging and angiography revealed high-intensity signals in the left basal ganglia and cerebral cortex and stenosis of the left middle cerebral artery. After 2 days, the middle cerebral artery stenosis improved. After 5 days, diffusion-weighted imaging showed an enlarged lesion in the left frontal cortex. The infarct in this case was due to a predominantly unilateral vasoconstrictive hypoxic brain injury from wasp stings.

Objective: Peripheral arterial disease (PAD) reduces functional activity and increases the rate of cardiovascular death in the elderly. Our study aimed to determine whether the presence of PAD in stroke patients affected the progression of disability or death one year after discharge. Methods: From April 2012 to March 2013, consecutive first stroke patients above 50 years of age without known PAD were enrolled. PAD was defined as a low ankle-brachial index (less than 0.9) measured by an automatic device. Clinical data associated with the stroke were collected from medical records. Disability in stroke patients was evaluated with the modified Rankin scale (mRS) on discharge day and one year after the index stroke. Progression of disability was defined as an increase in mRS more than one level at one year. Results: Among the 526 patients, 238 had ischemic strokes and underwent ankle-brachial index (ABI) measurement. Of them, 192 patients were included. In univariate analysis, age, dyslipidemia, discharge mRS, low-density lipoprotein cholesterol, D-dimer, homocysteine, internal carotid artery stenosis, posterior cerebral artery stenosis, and PAD were factors associated with worsening mRS. After adjustment for these factors in the logistic regression analysis, PAD was an independent factor associated with worsening mRS. In the analysis of one-year mortality, patients with PAD had a higher death rate, but PAD was not an independent factor after adjusting for other variables. Conclusions: The presence of PAD in stroke patients suggests a chance of disability progression, but may not be a predictor of death after one year.

Background & Objective: The number of ischemic stroke is increasing steadily. The recent stroke prevention strategies have targeted risk factors for preventing ischemic stroke. Community-based data that quantify the prevalence of these risk factors are needed to develop effective stroke prevention strategies. This study was performed aiming to establish customized prevention strategies by investigating vascular risk factors of ischemic stroke among the healthy adults in an urban population in Korea. Methods: The Prevention of Stroke and Dementia (PRESENT) survey collected data associated with stroke risk factors between 2007 and 2009 in Ansan city, Korea. Of 46,537 people, 2,843 were selected by random sampling, and final population included 358 men and 422 women over 50 years old. We checked modifiable risk factors, such as hypertension, diabetes mellitus, smoking, hyperlipidemia, atrial fibrillation, cardiovascular disease, obesity, and physical inactivity. Results: The mean age of study subjects was 60.1±8.2 years; 55.5% had hypertension, 18.6% had diabetes mellitus, 17.7% were current smoker, 44.9% had hyperlipidemia, 1.7% had atrial fibrillation, and 4.5% had cardiovascular disease. Men had more risk factors for stroke, and higher rates of diabetes mellitus and current smoking. However, women had higher cholesterol and obesity rates and lower physical activity. The proportion of individuals with >1 risk factor for stroke increased with age. Hypertension, diabetes mellitus, and cardiovascular diseases also increased with age, but low-density lipoprotein levels and current smoking decreased. Conclusions: This study provides valuable information to develop customized strategic policies for primary and secondary stroke prevention.

BACKGROUND AND PURPOSE: The systemic inflammatory response syndrome(SIRS), as defied recently by critical-care specialists, may result from various etiologies including infection, bum, or trauma. The purpose of this study was to determine whether TNF- alpha is associated with the development of systemic inflammatory response syndrome caused by multiple trauma. METHODS: The study population consisted of 21 patients with multiple trauma presented emergency department within 2 hours after insult were enrolled in this study Multiple blood samples were serially drawn to measure seam TNF-alpha level on admission, 12 hours, 24 hours, and every day until 5 days after injury. Serum TNF-alpha was measured by ELISA ("Sandwich type"). Blood samples of fifteen volunteers were used as a reference value far serum TNF-alpha. RESULTS: Serum TNF-alpha. levels of SIRS group were persistency elevated above reference value until 3 days after on admission. Peak seam TNF-alpha level at 12 hours after admission was higher in SIRS group than non-SIRS group(p< 0.05). There was no significant correlation between injury severity score and TNF-alpha levels on regression analysis, all patients with ISS higher than 16 had SIRS. No one had SIRS among patients with ISS less than 16. CONCLUSION: the result of this study suggests that persistent elevation of TNF-alpha and degree of injury severity are associated with the development of systemic inflammatory response syndrome in multiple trauma.

BACKGROUND: Current guidelines of advanced trauma life support recommend open thoracotomy when pericardiocentesis reveals bloody pericardial effusion in patients with blunt chest trauma. However, open thoracotomy may not be always required for treating patients alive until arriving emergency department, because rapid accumulation of the blood into pericardial space results in immediate death at scene. We report our experiences of treating traumatic pericardial effusion, and discuss the therapeutic modality in patients with traumatic pericardial effusion. METHODS: The study consisted of 37 patients(20 males and 17 females with the mean age 42) sustaining traumatic pericardial effusion. The patients were divided according to treatment modality into 3 groups(group I : patients receiving conservative management, group II : patients treated with pericardiocentesis, group III : patients required emergency thoracotomy). We compared clinical presentations, hemodynamic profiles and echocardiographic findings among three groups. RESULTS: Cardiac tamponade was present in 14 of 37 patients. Pericardiocentesis was performed in 13 patients, and open thoracotomy in 4 patients. Pericardiocentesis was curative in 9 patients. Thoracotomy was performed in only 3(24%) of 13 patients required pericardiocentesis. 3(75%) of 4 patients having moderate or severe pericardial effusion from penetrating injury were required open thoracotomy. CONCLUSION: In selected patients who have traumatic pericardial effusion by blunt chest injury, pericardiocentesis may be curative, and thoracotomy may not be inquired as long as bleeding via indwelling pericardial catheter is not sustained after pericardiocentesis.

BACKGROUND AND OBJECTIVES: No existing device for cardiopulmonary resuscitation(CPR)isdesignedto exploit both the "cardiac pump" and the "thoracic pump" simultaneously. This study was designed to assess the hemodynamic effects of simultaneous sterno-thoracic CPR (SST-CPR) vs. standard CPR (S-CPR) using a mechanical resuscitator in a canine model of cardiac arrest. DEVICE DESCRIPTION: We have built a device that depresses the sternum and circumferentially constricts the thorax simultaneously. This device has two components. The first component is a piston, which depresses the sternum. The second is a circumferential strap that constricts the thorax as the piston is pushed down on the sternum. MATERIALS AND METHODS: Twelve domestic dogs were enrolled in this study. After catheterizations to measure pressures from the aorta and the right atrium, ventricular fibrillation was induced by passing AC current to the right ventricle. After 4 minutes of cardiac arrest, S-CPR and SST-CPR were performed alternatively. Aortic pressure, right atrial pressure, cardiac output, and end tidal CO2 were measured while each method of CPR was performing. RESULTS: SST-CPR resulted in significantly higher mean arterial pressure than S-CPR (68.9+/-16.1 vs 30.5+/-10.0 mmHg, p<0.01). SST-CPR could generate higher coronary perfusion pressure than S-CPR (47.0+/-11.4 vs 17.3+/-8.9 mmHg, p<0.01). End tidal CO2 tension was also higher during SST-CPR than S-CPR (11.6+/-6.1 vs 2.17+/-3.3 mmHg, p<0.01). CONCLUSION: Simultaneous sternothoracic cardiopulmonary resuscitation is a new method of cardiopulmonary resuscitation, which can generate better hemodynamic effects than standard cardiopulmonary resuscitation.
