The NOTA Study (Non Operative Treatment for Acute Appendicitis): prospective study on the efficacy and safety of antibiotics (amoxicillin and clavulanic acid) for treating patients with right lower quadrant abdominal pain and long-term follow-up of conservatively treated suspected appendicitis.

OBJECTIVES: To assess the safety and efficacy of antibiotics treatment for suspected acute uncomplicated appendicitis and to monitor the long term follow-up of non-operated patients. BACKGROUND: Right lower quadrant abdominal pain is a common cause of emergency department admission. The natural history of acute appendicitis nonoperatively treated with antibiotics remains unclear. METHODS: In 2010, a total of 159 patients [mean AIR (Appendicitis Inflammatory Response) score = 4.9 and mean Alvarado score = 5.2] with suspected appendicitis were enrolled and underwent nonoperative management (NOM) with amoxicillin/clavulanate. The follow-up period was 2 years. RESULTS: Short-term (7 days) NOM failure rate was 11.9%. All patients with initial failures were operated within 7 days. At 15 days, no recurrences were recorded. After 2 years, the overall recurrence rate was 13.8% (22/159); 14 of 22 patients were successfully treated with further cycle of amoxicillin/clavulanate. No major side effects occurred. Abdominal pain assessed by the Numeric Rating Scale and the visual analog scale; median Numeric Rating Scale score was 3 at 5 days and 2 after 7 days. Mean length of stay of nonoperatively managed patients was 0.4 days, and mean sick leave period was 5.8 days. Long-term efficacy of NOM treatment was 83% (118 patients recurrence free and 14 patients with recurrence nonoperatively managed). None of the single factors forming the Alvarado or AIR score were independent predictors of failure of NOM or long-term recurrence. Alvarado and AIR scores were the only independent predictive factors of NOM failure after multivariate analysis, but both did not correlate with recurrences. Overall costs of NOM and antibiotics were &OV0556;316.20 per patient. CONCLUSIONS: Antibiotics for suspected acute appendicitis are safe and effective and may avoid unnecessary appendectomy, reducing operation rate, surgical risks, and overall costs. After 2 years of follow-up, recurrences of nonoperatively treated right lower quadrant abdominal pain are less than 14% and may be safely and effectively treated with further antibiotics.

Changes in the outcomes of severe trauma patients from 15-year experience in a Western European trauma ICU of Emilia Romagna region (1996-2010). A population cross-sectional survey study.

BACKGROUND: Our experience in trauma center management increased over time and improved with development of better logistics, optimization of structural and technical resources. In addition recent Government policy in safety regulations for road traffic accident (RTA) prevention, such compulsory helmet use (2000) and seatbelt restraint (2003) were issued with aim of decreasing mortality rate for trauma. INTRODUCTION: The evaluation of their influence on mortality during the last 15 years can lead to further improvements. METHODS: In our level I trauma center, 60,247 trauma admissions have been recorded between 1996 and 2010, with 2183 deaths (overall mortality 3.6 %). A total of 2,935 trauma patients with ISS >16 have been admitted to Trauma ICU and recorded in a prospectively collected database (1996-2010). Blunt trauma occurred in 97.1 % of the cases, whilst only 2.5 % were penetrating. A retrospective review of the outcomes was carried out, including mortality, cause of death, morbidity and length of stay (LOS) in the intensive care unit (ICU), with stratification of the outcome changes through the years. Age, sex, mechanism, glasgow coma scale (GCS), systolic blood pressure (SBP), respiratory rate (RR), revised trauma score (RTS), injury severity score (ISS), pH, base excess (BE), as well as therapeutic interventions (i.e., angioembolization and number of blood units transfused in the first 24 h), were included in univariate and multivariate analyses by logistic regression of mortality predictive value. RESULTS: Overall mortality through the whole period was 17.2 %, and major respiratory morbidity in the ICU was 23.3 %. A significant increase of trauma admissions has been observed (before and after 2001, p < 0.01). Mean GCS (10.2) increased during the period (test trend p < 0.05). Mean age, ISS (24.83) and mechanism did not change significantly, whereas mortality rate decreased showing two marked drops, from 25.8 % in 1996, to 18.3 % in 2000 and again down to 10.3 % in 2004 (test trend p < 0.01). Traumatic brain injury (TBI) accounted for 58.4 % of the causes of death; hemorrhagic shock was the death cause in 28.4 % and multiple organ failure (MOF)/sepsis in 13.2 % of the patients. However, the distribution of causes of death changed during the period showing a reduction of TBI-related and increase of MOF/sepsis (CTR test trend p < 0.05). Significant predictors of mortality in the whole group were year of admission (p < 0.05), age, hemorrhagic shock and SBP at admission, ISS and GCS, pH and BE (all p < 0.01). In the subgroup of patients that underwent emergency surgery, the same factors confirmed their prognostic value and remained significant as well as the adjunctive parameter of total amount of blood units transfused (p < 0.05). Surgical time (mean 71 min) showed a significant trend towards reduction but did not show significant association with mortality (p = 0.06). CONCLUSION: Mortality of severe trauma decreased significantly during the last 15 years as well as mean GCS improved whereas mean ISS remained stable. The new safety regulations positively influenced incidence and severity of TBI and seemed to improve the outcomes. ISS seems to be a better predictor of outcome than RTS.

Management and outcome of 308 cases of liver trauma in Bologna Trauma Center in 10 years.

INTRODUCTION: Management of Liver Trauma may vary widely from NOM +/- angioembolization to Damage Control Surgery. Multidisciplinary management is essential for achieving better outcomes. MATERIAL AND METHODS: During 2000-2009 period 308 patients with liver injury were admitted to level 1 trauma center and recorded in Trauma Registry. Collected data are demographics, AAST grade, initial treatment (operative or non-operative treatment) and outcome (failure of NOM), death. All patients were initially assessed according to ATLS guidelines. In case of haemodynamic instability and FAST evidence of intra-abdominal free fluid, the patients underwent immediate laparotomy. Hemodynamically stable patients, underwent CT scan and were admitted in ICU for NOM. RESULTS: Two hundred fourteen patients (69.5%) were initially managed with NOM. In 185 patients this was successful. Within the other 29 patients, failure of NOM was due to liver-related causes in 12 patients and non-liver-related causes in 17 Greater the grade of liver injury, fewer patients could be enrolled for NOM (85.8% in I-II and 83.3% in III against 39.8% in IV-V). Of those initially treated non-operatively, the likelihood of failure was greater in more severely injured patients (24.4% liver-related failure rate in IV-V against the 1.3% and 1.0% in I-II and III respectively). One hundred twenty-three patients (40% of the whole population study--308 patients) underwent laparotomy: 94 immediately after admission, because no eligible for NOM; 29 after NOM failure . In the 81 patients in which liver bleeding was still going on at laparotomy, hemostasis was attempted in two different ways: in the patients affected by hypothermia, coagulopathy and acidosis, perihepatic packing was the treatment of choice. In the other cases a "direct repair" technique was preferred. "Early mortality" which was expected to be worse in patients with such metabolic derangements, was surprisingly the same of the other group. This proves efficacy of the packing technique in interrupting the "vicious cicle" of hypothermia, coagulopathy and acidosis, therefore avoiding death ("early death" in particular) from uncontrollable bleeding. CONCLUSION: NOM +/- angioembolization is safe and effective in any grade of liver injury provided hemodynamic stability. DCS is Gold Standard for hemodynamically unstable patients.

Exploring the Efficacy of a Mindfulness Program for Boys With Attention-Deficit Hyperactivity Disorder and Oppositional Defiant Disorder.

Objective: This study was the first attempt to explore the efficacy of a mindfulness protocol for children with attention-deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD), and their parents. Method: Fifty male children with ADHD and ODD diagnosis, aged 8 to 12, were randomly assigned to the mindfulness intervention (n = 25) or the wait-list (n = 25) group. Outcome measures included children, parents', and teachers' reports and objective measures of attention. Results: Children from the intervention group had a greater reduction in hyperactive behaviors in the school context (effect size [ES] = 0.59) and a greater improvement in visual sustained attention (ES = 0.77) and in Avoidance and Fusion Questionnaire scores (ES = 0.43) than those in the wait-list control group. No significant effect of the intervention on aggressive behaviors was revealed. Conclusion: A mindfulness intervention for children and their parents showed partial beneficial effects in children with ADHD + ODD.

[The Elhers-Danlos syndrome: an insidious pathology. Presentation of a familiary group]. / La sindrome di Elhers-Danlos: una patologia insidiosa. Presentazione di un gruppo familiare.

INTRODUCTION: Elhers-Danlos Syndrome (EDS) is an hereditary disease of the connective tissue, which may have clinical appearances varying in its severity from subclinical asymptomatic forms up to dramatic uncontrollable haemorrhage. MATERIALS AND METHODS: We have observed three siblings who were carriers of vascular type EDS. They were otherwise healthy at the time of the disease presentation and have become symptomatic since then, developing severe and uncontrollable haemorrhage. RESULTS: We have reported the clinical presentation of this syndrome, the clinical and laboratory characteristics, the treatment and the outcome. CONCLUSIONS: Although the severity of this disease, Elhers-Danlos Syndrome becomes symptomatic lately and suddenly in its course, often during emergency surgery for haemorrhagic shock. Several issues are raised such as the possibility for early diagnosis of this disease, the psychological features of a genetic counseling, the need for the patients to have adequate lifestyle and last but not least the risk of genetic transmission of the disease.

[Penetrating abdominal trauma: 20 years experience in a Western European Trauma Center]. / Traumi penetranti dell'addome. Esperienza di 20 anni in Trauma Center dell'Europa Occidentale.

BACKGROUND: The incidence of penetrating abdominal trauma in Western Europe is low. While non-operative management of blunt trauma has become the gold standard, the management of penetrating trauma is still controversial. Nonoperative management (NOM) and laparoscopy are currently used in selected patients, reducing the rate of unnecessary laparotomy. METHODS: We retrospectively reviewed a 20-years period from the Trauma Registry of our Trauma Center. 6523 patients were admitted for thoraco-abdominal trauma (5861 blunt vs 662 penetrating). We sorted the 114 patients with penetrating abdominal trauma in 2 groups for period (1989-2000 vs 2001-08, before and after the establishment of dedicated trauma unit) analyzing their demographics, clinical, therapeutic characteristics and the outcome in comparison. RESULTS: In the latest period a significant increase in the incidence of penetrating trauma has been observed (doubled from 4.17/year up to 8.53/year, accounting now for 13.95% of all trauma laparotomies vs 7.8% in the past decade). A reduction of GSW (30% vs 12.5%, p = ns) occurred while no differences have been recorded in sex, age, prognostic parameters at arrival such as mean GCS (11.8 vs 13.2), ISS (22 vs 18), pH, BE and blood transfusion (6.4 vs 4.3 U) requirement. Interestingly a markedly significant change has been observed in the demographics of the victims (67.2% were of extra-EU origin vs 8% in the previous decade, p < 0.01). Recently the use of NOM spread widely in selected stable patients (21.9%). The failure rate of NOM was 14.3%. The percentage of unnecessary laparotomies decreased from 36% to 21.1% (p = ns). The introduction of laparoscopy was helpful in achieving a reliable, less invasive exploration, allowing detection of the peritoneal penetration and complete visceral exploration. Two GSW (4%) vs 3 (5.8%) cases of the latest years required Damage Control Surgery. A recent significant reduction in mortality and morbidity rate has been recorded (respectively 3.85% vs 18%, p < 0.05; 20% vs 39%, p = ns). CONCLUSION: The recent immigration phenomenon and social changes contributed towards a significant rise in the incidence of penetrating trauma in Italy in the last decade associated to changes in the mechanism of injury. The increased use of NOM and laparoscopy contributed in decreasing the incidence of unnecessary laparotomies as well as overall morbidity and mortality.

[The damage control surgery]. / Damage control surgery: orientamenti attuali.

AIM OF THE STUDY: To evaluate our experience in the treatment of complex abdominal injuries with the principles of Damage Control Surgery (DCS). METHOD: A retrospective review was conducted of 55 patients with multiple abdominal injuries and severe haemorrhage induced hypothermia and acidosis admitted to the "Ospedale Maggiore Trauma Center" in Bologna from 1989 to June 2005. RESULTS: All the patients but one had major blunt trauma. Mean age was 40.1; mean ISS 42; mean RTS 4.11; extimated loss of blood was greater than 4000 ml. Packing provide definitive control of bleeding in 44 patients but 10 had recurrent bleeding or bleeding from different injuries such as bone fractures and required further surgery (2) or arterial embolization (8). Twenty eights patients (50.9%) died. Survival was strongly associated with the ISS, GCS, the loss of blood and acidosis. CONCLUSION: The Authors concluded that in selected circumstances the traditional approach to severe abdominal injuries is not appropiate. In this situation, alternative and aggressive treatment such as the Damage Control Surgery has been recommended as the procedure of choice.

[The education of the trauma surgeon: the "trauma surgery course" as advanced didactic tool]. / Modelli educazionali in chirurgia del trauma: il "Corso Teorico-Pratico di Chirurgia del Politrauma" come proposta di didattica avanzata.

BACKGROUND: The consequences of low incidence of penetrating injuries in Europe and of the increasing in nonoperative management of blunt trauma are a decrease in surgeons' confidence for managing traumatic injuries. The Corso Teorico Pratico di Chirurgia del Politrauma was developed as model for teaching operative trauma techniques. The aim of this retrospective study is to evaluate the effectiveness of the course and compare it with other similar courses. METHOD: The Corso Teorico Pratico di Chirurgia del Politrauma is a two day course and consists of lecture on trauma topics and porcine operative experience. Data on the first 124 participants were collected and analyzed. RESULTS: One hundred twenty general surgeons and 2 pediatric surgeons had participated at the course. All the participants judged the course an efficient model to improve knowledge on surgical treatment of trauma. CONCLUSION: A two days course, focused on trauma, with didactic lectures and operative life-like situations, can be a model for simulated education and useful to improve surgeons' confidence in trauma patients.

[Diagnosis and treatment of retroperitoneal traumatic injuries. Our experience on 221 patients]. / Le lesioni traumatiche del retroperitoneo: inquadramento diagnostico e terapeutico. Nostra esperienza su 221 pazienti.

BACKGROUND: The management of traumatic retroperitoneal injuries is still confusing to many surgeons. The presence of injuries of retroperitoneum generally worsens the prognosis in trauma patients and need more attention both the diagnosis and treatment and mortality is high comparated to abdominal traumati injuries. METHOD: A retrospective review was conducted of 221 patients with retroperitoneal injuries admitted to the Ospedale Maggiore Trauma Center in Bologna from 1989 to March 2005. RESULTS: Two hundred seven were blunt traumas and 14 penetrating. Mean age was 40.3; 25 patients died in operating room and 25 were treated with Damage Control Surgery for both abdominal and retroperitoenal injuries. The mortality rate was 15%. Data about surgical treatments, associate treatments for abdominal injuries, and need of reoperation are reported. CONCLUSION: Retroperitoneal traumatic injuries are challenging emergencies and need of attention and expertise by the suorgeon. Only with a careful judgement on the tactics and the procedure to carry on it is possible to gain valid results, which often means to safe the patients life.

Trauma-induced "Macklin effect" with pneumothorax and large pneumomediastinum, disguised by allergy.

A 56-year-old man presented spontaneously to the Emergency Department complaining of facial and neck oedema after assumption of nonsteroidal anti-inflammatory drugs (NSAIDS). The triage nurse assigned the patient to Accident & Emergency (A&E) doctor as probable allergic reaction to NSAIDS. Chest X-ray (CXR), ordered after 24 hours, revealed a huge subcutaneous chest and neck emphysema without clearly visible pneumothorax. Subsequent chest CT scan showed a small left pneumothorax and a large amount of air in the mediastinum. The patient was conservatively treated since he was eupnoeic and hemodynamically stable. The pathophysiology of pneumomediastinum was first described by Macklin in 1939. The Macklin effect involves alveolar ruptures with air dissection along bronchovascular sheaths to the mediastinum. In this case the patient did not report in his history a recent blunt thoracic trauma and the initial suspicion of an allergic reaction has prevented physicians to immediately achieve the correct diagnosis.

Dyspnea and large bowel obstruction: a misleading Chilaiditi syndrome.

Chilaiditi sign is named after the Greek radiologist Demetrius Chilaiditi who first described it when he was working in Vienna In (1910), and it is an incidental radiographic finding. This sign can be more frequently mistaken for pneumoperitoneum which is usually an indication of bowel perforation and can lead to needless surgical intervention. There are several case report reported in literature that describe the association between colonic volvulus and Chilaiditi syndrome that underline the frequent association between these anatomical condition instead no previous report described the association between Chilaiditi syndrome and large bowel obstruction secondary to a malignant sigmoid stenosis in a man presenting with symptoms and signs of upper respiratory distress combined with subacute bowel obstruction.

Refinement in the technique of perihepatic packing: a safe and effective surgical hemostasis and multidisciplinary approach can improve the outcome in severe liver trauma.

BACKGROUND: since 2005, we refined the technique of perihepatic packing including complete mobilization of the right lobe and packing around the posterior paracaval surface, lateral right side, and anterior and posteroinferior surfaces. METHODS: two groups of patients with grade IV/V liver trauma underwent perihepatic packing before and after 2005. The study group included 12 patients treated with the new technique. The control group included 23 patients treated with the old technique. RESULTS: all 13 patients except one who died within 24 hours were treated with the old technique. The overall survival rate was 75% in the patients treated with the new technique (vs 30.4%, P < .02); the liver-related mortality was 8.3% versus 34.8% (P = not significant). The mean survival time in the intensive care unit was longer in the latest group (39.4 vs 22.3 days, P = not significant). The incidence of rebleeding requiring repacking was 16.7% in the patients who underwent new packing versus 45.5% in the patient who were treated with the old technique (P = not significant). The overall (81.8% vs 100%, P = not significant) and liver-related morbidity rate (18.2% vs 41.7%, P = not significant) and the incidence of abdominal sepsis (9.1% vs 41.7%, P = not significant) decreased. CONCLUSIONS: our refined technique of perihepatic packing seems to be safe and effective.

The NOTA study: non-operative treatment for acute appendicitis: prospective study on the efficacy and safety of antibiotic treatment (amoxicillin and clavulanic acid) in patients with right sided lower abdominal pain.

BACKGROUND: Case control studies that randomly assign patients with diagnosis of acute appendicitis to either surgical or non-surgical treatment yield a relapse rate of approximately 14% at one year. It would be useful to know the relapse rate of patients who have, instead, been selected for a given treatment based on a thorough clinical evaluation, including physical examination and laboratory results (Alvarado Score) as well as radiological exams if needed or deemed helpful. If this clinical evaluation is useful, the investigators would expect patient selection to be better than chance, and relapse rate to be lower than 14%. Once the investigators have established the utility of this evaluation, the investigators can begin to identify those components that have predictive value (such as blood analysis, or US/CT findings). This is the first step toward developing an accurate diagnostic-therapeutic algorithm which will avoid risks and costs of needless surgery. METHODS/DESIGN: This will be a single-cohort prospective observational study. It will not interfere with the usual pathway, consisting of clinical examination in the Emergency Department (ED) and execution of the following exams at the physician's discretion: full blood count with differential, C reactive protein, abdominal ultrasound, abdominal CT. Patients admitted to an ED with lower abdominal pain and suspicion of acute appendicitis and not needing immediate surgery, are requested by informed consent to undergo observation and non operative treatment with antibiotic therapy (Amoxicillin and Clavulanic Acid). The patients by protocol should not have received any previous antibiotic treatment during the same clinical episode. Patients not undergoing surgery will be physically examined 5 days later. Further follow-up will be conducted at 7, 15 days, 6 months and 12 months. The study will conform to clinical practice guidelines and will follow the recommendations of the Declaration of Helsinki. The protocol was approved on November 2009 by Maggiore Hospital Ethical Review Board (ID CE09079). Trial Registration ClinicalTrials.gov identifier: NCT01096927.

Initial evaluation of the "Trauma surgery course".

BACKGROUND: The consequence of the low rate of penetrating injuries in Europe and the increase in non-operative management of blunt trauma is a decrease in surgeons' confidence in managing traumatic injuries has led to the need for new didactic tools. The aim of this retrospective study was to present the Corso di Chirurgia del Politrauma (Trauma Surgery Course), developed as a model for teaching operative trauma techniques, and assess its efficacy. METHOD: the two-day course consisted of theoretical lectures and practical experience on large-sized swine. Data of the first 126 participants were collected and analyzed. RESULTS: All of the 126 general surgeons who had participated in the course judged it to be an efficient model to improve knowledge about the surgical treatment of trauma. CONCLUSION: A two-day course, focusing on trauma surgery, with lectures and life-like operation situations, represents a model for simulated training and can be useful to improve surgeons' confidence in managing trauma patients. Cooperation between organizers of similar initiatives would be beneficial and could lead to standardizing and improving such courses.
