Clinicians must be able to recognize post-extraction complications and treat them in a timely manner; complications that may potentially be life-threatening require special attention. Although arteriovenous malformation (AVM) is a very rare disorder, it may induce life-threatening hemorrhage during surgical intervention in the pertinent site. The present article examines the diagnosis and treatment modalities of AVM based on the case of a patient who was diagnosed with AVM with continuous bleeding after tooth extraction and who was successfully treated.

Purpose: The purpose of this study was to identify the types of errors that occurred and were recovered in a simulated transfusion scenario by nursing students. Methods: Twenty-eight teams of a total of 89 nursing students participated in a transfusion simulation using a high fidelity simulator. Data were collected by observing rule based errors and built in errors recovered according to the framework of Eindhoven model. Reflective journaling was used to identify perceived safety-threatening errors and commitment to improvement. Data were analyzed using descriptive statistics. Results: All teams committed the rule based errors in the scenario. The most common errors occurred in the coordination category related to communication with physician. Most of students perceived the transfusion reaction as a safety-threatening error. Conclusion: The findings indicate that students lack patient safety competence. The simulation training to decrease errors and improve safe practice provides nursing students with an effective strategy to develop patient safety competence.

Traumatic pseudoaneurysms in the head and neck region are very rare. Particularyly, pseudoaneurysms of the internal maxillary artery are known to be very rare. The authors report a 20-year old male who was diagnosed as having a pseudoaneurysm of the internal maxillary artery. The cause was assumed to be a mandible ramus fracture. When he visited our emergency room, we did not consider a pseudoaneurysm because of his other life-threatening conditions. Fortunately, he re-visited our hosipital before the aneurysm ruptured. He was diagnosed with angiography and was treated by using embolization with glue. The rupture of the pseudoaneurysm could have caused a life-threatening hemorrhage.

Reexpansion pulmonary edema[ RPE ] with hypoxemia and hypotension is a very rare complication of the treatment of lung collapse secondary to pneumothorax and pleural effusion. We experienced two cases of RPE. One is a 29 year old male with complete right pneumothorax and the other is a 20 year old female with massive right pleural effusion. Life threatening pulmonary edema was developed soon after insertion of chest tube in both. Fortunately, RPE was detected early and intensive treatment was performed. They were discharged without complication. Although RPE with hypoxemia and hypotension is rare , it is very serious and occasionally life-threatening. So, chest surgeon treating lung collapse must be aware of the possibility of RPE and make an effort to prevent the occurence of this condition.

We focus on the Real time Fire Scheduling Problem (RFSP), the problem of determining the sequence of targets to be fired at, for the objective of minimizing threatening probability to achieve tactical goals. In this paper, we assume that there are m available weapons to fire at n targets (> m) and the weapons are already allocated to targets. One weapon or multiple weapons can fire at one target and these fire operations should start simultaneously while the finish time of them may be different. We suggest mathematical modeling for RFSP and several heuristic algorithms. Computational experiments are performed on randomly generated test problems and results show that the suggested algorithms outperform the firing method which is generally adopted in the field artillery.

In this paper, the authors introduced a new approach to find the optimal collision avoidance maneuver considering multi threatening objects within short period, while satisfying constraints on the fuel limit and the acceptable collision probability. A preliminary effort in applying a genetic algorithm (GA) to those kinds of problems has also been demonstrated through a simulation study with a simple case problem and various fitness functions. And then, GA is applied to the complex case problem including multi-threatening objects. Two distinct collision avoidance maneuvers are dealt with: the first is in-track direction of collision avoidance maneuver. The second considers radial, in-track, cross-track direction maneuver. The results show that the first case violates the collision probability threshold, while the second case does not violate the threshold with satisfaction of all conditions. Various factors for analyzing and planning the optimal collision avoidance maneuver are also presented.

A 12-year-old, intact female Jindo was referred to our clinic due to the enlargement of all lymph nodes, as well as severe dyspnea. All palpatible lymph nodes were highly swelling and enlargement. The dog was diagnosed as end stage of multicentric lymphoma with multi-organ metastasis. In addition, the dog was diagnosed as having a pulmonary thromboembolism via computed tomography (CT) and D-dimer concentrations and prothrombin time (PT) results. This case report describes that lymphoma can be associated with pulmonary thromboembolism which is life threatening complication in dogs. The present case was managed successfully with chemotherapy and antithrombotic treatment.

Congenital cystic adenomatoid malformation is a rare, but well-known disease. It can be managed conservatively in patients without symptoms or require surgical removal when symptomatic. The surgical option of choice is en bloc resection of the affected lesion. We report an experience of life-threatening congenital cystic adenoid malformation in a low-birth-weight (1,590 g) premature neonate who was successfully treated with a lobectomy of the lung.

Alexander the Great was a world-class leader with tremendous courage. He paid no heed to the dangers of the battlefield, so he was always in the front lines. However, his excessive courage put his life in danger. Herein, we present an analysis of the information contained in the chronicles about a very severe, life-threatening thoracic trauma that nearly killed the great stratelates. The detailed descriptions made by Arrianus allow us to conclude that Alexander the Great experienced a nearly fatal case of tension pneumothorax. Information on how he was managed is also presented.
