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.

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.

[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.
