Eurasian J Med. 2017 Jun;49(2):137-141. doi: 10.5152/eurasianjmed.2017.16102. Epub 2017 Apr 28.
The buildings, working personnel, and patients and their relatives may directly or indirectly be affected by the disasters. Here we will discuss evacuation, establishing a field hospital, communication, the role of the media in disasters, and defending against sabotage. The affected individuals should be evacuated and transferred to secure zones safely and rapidly. How the decision for evacuation should be made and how the evacuation triage should be performed are important issues. Field hospitals should be established within the bounds of possibility for continuation of the treatments of evacuated people. The standards for the field hospitals and its sections that may be created according to the needs will be explained. Undoubtedly, since one of the most important subjects in disasters is communication, the types of communication in disasters and their significance will be mentioned. How the relationships with the media should be an aspect of communication and how they can be beneficially used will also be mentioned. As in all organizations and institutions, sabotage attempts may also be present concerning health facilities. For this reason, during the preparation of the hospital disaster plan, defending against sabotage will be discussed, and what should be done at that stage will be mentioned.

Comprensión de la detección de animales de los sonidos precursores del terremoto.
Understanding Animal Detection of Precursor Earthquake Sounds.
Animals (Basel). 2017 Aug 31;7(9). pii: E66. doi: 10.3390/ani7090066.
Abstract
We use recent research to provide an explanation of how animals might detect earthquakes before they occur. While the intrinsic value of such warnings is immense, we show that the complexity of the process may result in inconsistent responses of animals to the possible precursor signal. Using the results of our research, we describe a logical but complex sequence of geophysical events triggered by precursor earthquake crustal movements that ultimately result in a sound signal detectable by animals. The sound heard by animals occurs only when metal or other surfaces (glass) respond to vibrations produced by electric currents induced by distortions of the earth's electric fields caused by the crustal movements. A combination of existing measurement systems combined with more careful monitoring of animal response could nevertheless be of value, particularly in remote locations.

Desastres naturales e indicadores de cohesión social.
Natural disasters and indicators of social cohesion.
PLoS One. 2017 Jun 7;12(6):e0176885. doi: 10.1371/journal.pone.0176885. eCollection 2017.
Abstract
Do adversarial environmental conditions create social cohesion? We provide new answers to this question by exploiting spatial and temporal variation in exposure to earthquakes across Chile. Using a variety of methods and controlling for a number of socio-economic variables, we find that exposure to earthquakes has a positive effect on several indicators of social cohesion. Social cohesion increases after a big earthquake and slowly erodes in periods where environmental conditions are less adverse. Our results contribute to the current debate on whether and how environmental conditions shape formal and informal institutions.

Thrombocytopenia in pregnancy - pathogenesis and diagnostic approach.

Abstract
Thrombocytopenia (TP) affects 7-10% of pregnant women. It occurs 4 times more frequently in pregnancy than in the non-pregnant women population. Women with thrombocytopenia in pregnancy are a heterogeneous and poorly known group. There are several possible causes of thrombocytopenia in pregnancy. The most common are: gestational thrombocytopenia (GE) (60-75%), preeclampsia (PE) and HELLP(hemolysis, elevated liver enzymes, low platelets) syndrome associated TP (21%), and idiopathic immune thrombocytopenia (ITP) (3-10%). Although thrombocytopenia diagnosed in pregnancy in most cases has a mild course, it has also been reported to be associated with a higher rate of preterm birth and premature detachment of the placenta. Some cases of severe thrombocytopenia with systemic involvement are associated with high risk of serious perinatal complications and require early diagnosis, careful clinical monitoring and medical treatment. The differential diagnosis and proper assessment of clinical risk of TP during pregnancy may be of great concern. The article discusses these issues, focusing on pathophysiology of TP in pregnancy.

Abstract
Laparoscopic hepatectomy carries a high risk of gas embolism due to the extensive hepatic transection plane and large hepatic vena cava. Here, we compared the influence of inhaled and intravenous anesthetics on gas embolism during laparoscopic hepatectomy. Fifty patients undergoing laparoscopic hepatectomy were divided into two groups to receive sevoflurane anesthesia (group S, n = 25) or intravenous propofol anesthesia (group p, n = 25). During the operation, gas emboli were detected by transesophageal echocardiography and graded according to their size. Venous CO2 emboli were detected in all patients, and the embolism grades did not differ between the two groups. However, the mean embolism episode duration was longer in group S than group P (51.24±23.59 vs. 34.00±17.13 sec, p < 0.05). At the point of the most severe gas embolism, the PTCO2 was higher in group S than group p (44.00±4.47 vs. 41.36±2.77 mmHg, p < 0.05), while the PO2/FiO2 (450.52±54.08 vs. 503.80±63.18, p < 0.05) and pH values (7.35±0.05 vs. 7.38±0.02, p < 0.05) were lower in group S than group P. Patients with a history of abdominal surgery or liver cirrhosis had higher gas embolism grades. Thus volatile anesthetics may lengthen the duration of embolism episodes and worsen hemodynamics and pulmonary blood gas exchange during surgery.

Complicaciones circulatorias y respiratorias en la insuflación con dióxido de carbono
Circulatory and respiratory complications of carbon dioxide insufflation.

Abstract
BACKGROUND: Although providing excellent outcome results, laparoscopy also induces particular pathophysiological changes in response to pneumoperitoneum. Knowledge of the pathophysiology of a CO(2) pneumoperitoneum can help minimize complications while profiting from the benefits of laparoscopic surgery without concerns about its safety. METHODS: A review of articles on the pathophysiological changes and complications of carbon dioxide pneumoperitoneum as well as prevention and treatment of these complications was performed using the Medline database. RESULTS: The main pathophysiological changes during CO(2) pneumoperitoneum refer to the cardiovascular system and are mainly correlated with the amount of intra-abdominal pressure in combination with the patient's position on the operating table. These changes are well tolerated even in older and more debilitated patients, and except for a slight increase in the incidence of cardiac arrhythmias, no other significant cardiovascular complications occur. Although there are important pulmonary pathophysiological changes, hypercarbia, hypoxemia and barotraumas, they would develop rarely since effective ventilation monitoring and techniques are applied. The alteration in splanchnic perfusion is proportional with the increase in intra-abdominal pressure and duration of pneumoperitoneum. CONCLUSION: A moderate-to-low intra-abdominal pressure (<12 mm Hg) can help limit the extent of the pathophysiological changes since consecutive organ dysfunctions are minimal, transient and do not influence the outcome.
Efectos de los diferentes niveles de presión expiratoria final en la hemodinámica, la mecánica respiratoria y la respuesta al estrés sistémico durante la colecistectomía laparoscópica.
Effects of different levels of end-expiratory pressure on hemodynamic, respiratory mechanics and systemic stress response during laparoscopic cholecystectomy.

Abstract
OBJECTIVE: General anesthesia causes reduction of functional residual capacity. And this decrease can lead to atelectasis and intrapulmonary shunting in the lung. In this study we want to evaluate the effects of 5 and 10cmH2O PEEP levels on gas exchange, hemodynamic, respiratory mechanics and systemic stress response in laparoscopic cholecystectomy. METHODS: American Society of Anesthesiologist I-II physical status 43 patients scheduled for laparoscopic cholecystectomy were randomly selected to receive external PEEP of 5cmH2O (PEEP 5 group) or 10cmH2O PEEP (PEEP 10 group) during pneumoperitoneum. Basal hemodynamic parameters were recorded, and arterial blood gases (ABG) and blood sampling were done for cortisol, insulin and glucose level estimations to assess the systemic stress response before induction of anesthesia. Thirty minutes after the pneumoperitoneum, the respiratory and hemodynamic parameters were recorded again and ABG and sampling for cortisol, insulin, and glucose levels were repeated. Lastly hemodynamic parameters were recorded; ABG analysis and sampling for stress response levels were taken after 60minutes from extubation. RESULTS: There were no statistical differences between the two groups about hemodynamic and respiratory parameters except mean airway pressure (Pmean). Pmean, compliance and PaO2; pH values were higher in 'PEEP 10 group'. Also, PaCO2 values were lower in 'PEEP 10 group'. No differences were observed between insulin and lactic acid levels in the two groups. But postoperative cortisol level was significantly lower in 'PEEP 10 group'.
CONCLUSION: Ventilation with 10cmH2O PEEP increases compliance and oxygenation, does not cause hemodynamic and respiratory complications and reduces the postoperative stress response.
