[PMID: 23917893 DOI: 10.1007/s00101-013-2207-5] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2013] [Revised: 06/17/2013] [Accepted: 06/20/2013] [Indexed: 10/26/2022]
Abstract
BACKGROUND Primary care physicians and specialists often refer patients to the emergency department with a specific diagnosis and request for admission. Such an external diagnosis frequently influences the initial evaluation in the emergency department. The present study aimed to evaluate the accuracy of such external diagnoses and to assess the consequences of incorrect diagnoses on length of stay and number of specialty consultations in the emergency department. MATERIAL AND METHODS This was a prospective observational study over the course of 3 months in the emergency department of a tertiary care center. External admission diagnoses made by primary care physicians and specialists were categorized as "accurate", "partially accurate" and "inaccurate". A special analysis of the external admission diagnosed was performed for patients admitted directly to an intermediary care unit and intensive care unit or patients who were transferred directly from the emergency department to the operating room. RESULTS Data for 784 patients were analyzed. Patients were on average 63.1 ± 19.5 years old (minimum-maximum 18-97 years, median 68 years) and 54 % were male. After emergency department evaluation and treatment 57.8 % of external diagnoses were categorized as accurate, 23.6 % as partially accurate and 18.6 % as inaccurate. Patients with partially accurate and inaccurate diagnoses had a 3 and 6.5 times higher rate of specialty consultations in the emergency department, respectively, when compared with patients with an accurate diagnosis (number of specialty consultations n = 0: 77.3 % vs. 54.1 % vs. 92.9 %, p < 0.05; n = 1: 20.0 % vs. 40.4 % vs. 6.2 %, p < 0.05; n = 2: 2.7 % vs. 5.5 % vs. 0.9 %, p < 0.05, respectively. Patients with an accurate diagnosis had a shorter total length of stay than patients with a partially accurate or inaccurate diagnosis [mean ± SD (min-max; median): 192 ± 108 min (10-707 min; 181 min) vs. 246 ± 126 min (27-1,026 min; 214 min) vs. 258 ± 138 min (22-700 min; 232 min), p < 0.001], respectively. Out of 85 patients admitted directly to an intermediary care unit, intensive care unit and patients who were transferred directly from the emergency department to the operating room the diagnosis was accurate, partially accurate and inaccurate in 56.5 %, 24.7 % and 18.8 %, respectively. CONCLUSIONS Admission diagnoses made by primary care physicians and specialists who subsequently refer patients to the emergency department are subject to certain inaccuracies. Inaccurate admission diagnoses are associated with an increased length of stay and a considerably higher rate of specialty consultation in the emergency department. Standardized operating procedures, treatment algorithms and triage systems are important to identify such incorrect diagnoses so that these patients can undergo appropriate diagnostic investigation and treatment.

Abstract
The accumulation of aggregated mutant huntingtin (mHtt) inclusion bodies is involved in Huntigton’s disease (HD) progression. Medium sized-spiny neurons (MSNs) in the corpus striatum are highly vulnerable to mHtt aggregate accumulation and degeneration, but the mechanisms and pathways involved remain elusive. Here we have developed a new model to study MSNs degeneration in the context of HD. We produced organotypic cortico-striatal slice cultures (CStS) from HD transgenic mice mimicking specific features of HD progression. We then show that induction of autophagy using catalytic inhibitors of mTOR prevents MSNs degeneration in HD CStS. Furthermore, disrupting autophagic flux by overexpressing Atg4b in neurons and slice cultures, accelerated mHtt aggregation and neuronal death, suggesting that Atg4b-dependent autophagic flux influences HD progression. Under these circumstances induction of autophagy using catalytic inhibitors of mTOR was inefficient and did not affect mHtt aggregate accumulation and toxicity, indicating that mTOR inhibition alleviates HD progression by inducing Atg4b-dependent autophagic flux. These results establish modulators of Atg4b-dependent autophagic flux as new potential targets in the treatment of HD.

Abstract
Patients with multiple trauma presenting with apnea or a gasping breathing pattern (respiratory rate < 6/min) require prehospital endotracheal intubation (ETI) and ventilation. Additional indications are hypoxia (S(p)O(2) < 90% despite oxygen insufflation and after exclusion of tension pneumothorax), severe traumatic brain injury [Glasgow Coma Scale (GCS) < 9], trauma-associated hemodynamic instability [systolic blood pressure (SBP) < 90 mmHg] and severe chest trauma with respiratory insufficiency (respiratory rate > 29/min). The induction of anesthesia after preoxygenation is conducted as rapid sequence induction (analgesic, hypnotic drug, neuromuscular blocking agent). With the availability of ketamine as a viable alternative, the use of etomidate is not encouraged due to its side effects on adrenal function. An electrocardiogram (ECG), blood pressure measurement and pulse oximetry are needed to monitor the emergency anesthesia and the secured airway. Capnography is absolutely mandatory to confirm correct placement of the endotracheal tube and to monitor tube dislocations as well as ventilation in the prehospital and hospital setting. Because airway management is often complicated in trauma patients, alternative devices need to be available preclinical and a fiber-optic endoscope should be available within the hospital. Use of these alternative measures for airway management and ventilation should be considered at the latest after a maximum of three unsuccessful endotracheal intubation attempts. Emergency medical service (EMS) physicians should to be trained in emergency anesthesia, ETI and alternative methods of airway management on a regular basis. Within hospitals ETI, emergency anesthesia and ventilation are to be conducted by trained and experienced anesthesiologists. When a difficult airway or induction of anesthesia is expected, endotracheal intubation should be supervised or conducted by an anesthesiologist. Normoventilation should be the goal of mechanical ventilation. After arrival in the resuscitation room the ventilation will be controlled and guided with the help of arterial blood gas analyses. After temporary removal of a cervical collar, the cervical spine needs to be immobilized by means of manual in-line stabilization when securing the airway.

Abstract
The overall incidence of severe head, face and neck injuries as seen from the German Trauma Registry of the National Association of German Trauma Surgeons is 81.3%. The leading causes of death among these patients are hemorrhage and severe traumatic brain injury. The aim of prehospital emergency medical care is to stabilize vital functions in order to ensure primary survival and to reduce morbidity with appropriate prehospital treatment of the individual injuries within the overall injury pattern. In this review, special aspects as well as pitfalls of the prehospital management of patients with head, face and neck injuries are demonstrated. Prehospital airway management concepts as well as concepts for stopping bleeding in the head, face and neck region are discussed in detail.

Abstract
BACKGROUND Emergency treatment and resuscitation within hospitals are managed by so-called medical emergency teams (MET). The present study examined the circumstances, number, initial treatment and further hospital course of in-hospital emergency cases at a level 1 university hospital. METHODS A retrospective study of in-hospital emergencies on the surgical wards of a university hospital including all non-intensive care areas from January 2007 to June 2010 was carried out. A self-developed documentation protocol which was introduced in 2006 was used by the MET to document general patient characteristics and details of the emergency treatment. These data included the place where the emergency situation arose, the patient's assignment to a surgical discipline, a detailed description of the emergency situation, the effectiveness of basic life support measures as well as the further hospital course of the patient. RESULTS A total of 235 emergency cases were documented within the study period of 3.5 years. The frequency of in-hospital emergencies was 4/1,000 admitted patients per year. Cardiac arrest was encountered in 31,5%. Out of all patients 54,5% were admitted to an intensive care unit. CONCLUSION The tasks of a MET at a surgical university hospital go beyond mere cardiopulmonary resuscitation. Emergency cases within the full spectrum of perioperative complications are encountered. Further multicenter studies with standardized protocols are required to analyze the management of German in-hospital emergencies.

Abstract
In recent years the number of interdisciplinary emergency departments (ED) at hospitals in Germany has increased. The model of decentralized first contact units for each medical discipline has been abandoned, last but not least due to economic considerations. While decentralized units could be staffed with personnel from each discipline there is much controversy surrounding the question of which kind of doctor is best suited for a centralized ED. The development of programs providing the necessary qualification for German ED physicians in the future by working groups of several specialties is still nascent and has not yet produced concrete results. However, even without these special training programs, the management of critically ill or severely injured patients in the ED is paramount. The smooth operation of centralized EDs is therefore important. Therefore, taking into account economical aspects, qualification and number of available personnel, this article introduces a staffing concept as a rational basis for an optimized patient management in centralized EDs in Germany. Taking the patient characteristics, the specific treatment modalities and the number of admissions to the ED into account, this paper will determine treatment time per patient and the necessary number of physicians, as well as an optimized staffing model for EDs.

Abstract
Aortic aneurysms are frequent in the elderly who often suffer from relevant co-morbidities. In Germany it is estimated that approximately 250,000 patients suffer from an aortic aneurysm. Due to the high risk of cardiac or pulmonary complications operative management poses a challenge to the anesthesiologist. Especially hemodynamic management during aortic cross-clamping requires anesthesiologic know-how and an anticipatory use of vasodilators and catecholamines. Furthermore, the anesthesiologist has to protect renal function. In order to avoid paraplegia due to spinal ischemia cerebrospinal fluid drainage may be necessary in patients with aneurysms of the thoracic aorta. In recent years endovascular repair of aortic aneurysms has been established in addition to conventional open surgery. As a consequence in some patients aortic surgery can be performed under regional or local anesthesia. In special cases thoracic endovascular repair requires a medicinal induction of heart arrest or the reduction of aortic blood flow by overpacing.

Abstract
BACKGROUND Time plays a crucial role in treating multiple traumatized patients and delays in management worsen the prognosis. Furthermore, current studies show that trauma patients profit from primary delivery to a trauma center. Therefore, the goal of physician-staffed ground and air rescue services in Germany is to treat these patients as quickly as possible and deliver them to a suitable trauma center. The aim of the present study was to investigate prehospital treatment times for the air rescue team in terms of disposition and efficiency when a ground rescue team was already present at the scene. METHODS In a nationwide, multicenter analysis emergency missions carried out for traumatological emergencies in 2006 by 28 air rescue centers (ARC) of the TeamDRF and 6 ARC of the federal police were evaluated using the medical database MEDAT of the German Air Rescue Service. A distinction was made between combined missions with (MEDAT 1 group) and without (MEDAT 2 group) physician-staffed ground emergency medical services already being present at the emergency site and in particular the rescue helicopter treatment times for both groups were investigated. Furthermore, combined missions (MAN 1 group) and solo missions (MAN 2 group) for traumatological emergencies in the period 01.05.2006 to 31.01.2007 were investigated in a complementary prospective regional study at the ARC Heidelberg/Mannheim "Christoph 53". In both groups the total treatment times for all physician-staffed emergency systems involved in treatment at the scene were investigated. RESULTS Nationwide, 26,010 primary missions could be evaluated and of these, 11,464 missions were traumatological emergencies (44.1%) with 2,229 (19.4%) carried out by the MEDAT 1 group and 9,235 (80.6%) by the MEDAT 2 group. For both groups the helicopter treatment times depended on the severity of the injuries (NACA classification) and were between 17+/-12 min (NACA I) and 34+/-19 min (NACA VII) in MEDAT group 1 versus 21+/-10 and 36+/-19 min in MEDAT group 2 (p<0.05, p<0.001), respectively. In the MEDAT 1 group, the average treatment times were between 2.8 min (NACA VII) and 8.1 min (NACA VI) shorter compared with the MEDAT 2 group. Moreover, when taking the severity of the injury into consideration, a regular and significantly higher treatment effort (e.g. intubation, repositioning and chest tube insertion) and a greater proportion of patients who were transported to the clinic via rescue helicopter were observed for the MEDAT 1 group than for the MEDAT 2 group. In the regional study 670 primary missions were evaluated including 382 traumatological emergencies (57%). From these, 90 multiple trauma patients (NACA V) were not resuscitated or died at the scene, 58 from the MAN 1 group and 32 from the MAN 2 group, and were investigated more closely. The helicopter treatment times were comparable to those observed in the nationwide study and were found to be 26+/-12 min and 35+/-20 min (p<0.05), respectively. In the MAN 1 group the treatment times for the ground rescue services up to the time when the helicopter arrived was 22+/-11 min on average; the total treatment time was 48+/-15 min and 12+/-8 min longer than the time for the MAN 2 group, which was statistically significant. In the MAN 1 group the helicopter was alerted on average 17+/-15 min after the physician-staffed ground rescue services arrived at the emergency site. Treatment by the rescue helicopter teams was significantly more extensive in the MAN 1 group. CONCLUSIONS The treatment times for the helicopter were several minutes shorter when a physician-staffed ground rescue team had already arrived at the emergency site. However, it must be assumed that the total prehospital time is significantly longer for such missions. These results directly affect the disposition at the emergency dispatch center and indicate that when air rescue is required to transport a patient to hospital, the helicopter should be alerted at an early stage. In such settings, it is likely that initiating the operation in this way would improve the prognosis of severely injured patients and save costs.

Abstract
BACKGROUND Clarifying the cause of global developmental and speech delay is of considerable significance in pediatrics. We present the clinical phenotype of the 22q13 deletion syndrome - also known as Phelan-McDermid syndrome - and show the diagnostic options. PATIENT We report on a female patient with muscular hypotonia, tall stature, minor facial dysmorphism, retarded motor and mental development, and severe speech delay. METHOD Chromosomal analysis was performed first on peripheral lymphocytes on GTG-banded chromosomes. Fluorescence in situ hybridization (FISH) analysis was carried out using the dual-color LSI DiGeorge/VCFS Region Probe (TUPLE1, N25) (Vysis/Abbott) and the subtelomeric probe tel 22q13.3 (Tel Vysion 22q). RESULTS The analysis of metaphase chromosomes at 450 band resolution showed a normal female karyotype 46,XX. FISH analysis revealed a 22q13 deletion. CONCLUSION Muscular hypotonia and developmental delay are non-specific findings observed in many genetic syndromes. In association with severe speech delay and normal or advanced growth pediatricians should consider 22q13 deletion syndrome as a potential cause and initiate a genetic examination.
