Safety of a new biological adhesive after pancreatic resection.

AIM: Pancreatic fistula (PF) represents the main complication (10%-29%) after pancreatic surgery. Soft pancreatic texture with a not dilated pancreatic duct represent the major risk factors for PF. Mortality after pancreaticoduodenectomy (PD) is reported in several large series to be <5%. PF and local sepsis are the main causes of delayed arterial hemorrage with a high mortality rate (14-38%). Therefore, any effort should be implemented in order to reduce the incidence of PF. METHODS: In the present study we have extended the use of the biological adhesive Bioglue® to coat pancreatic resection surface after distal pancreasectomy (DP, N.=5) and pancreatico-jejunostomy (PJ) after PD (N.=18) in a RESULTS: Operative mortality was observed in 2 instances: one case after PJ leakage (1/18, 5.5%) and one case after DP not related to PF (1/5, 20%). PF has been documented in 7/23 (30,4%) after pancreatic resection, and in all cases after PD. In 3 cases PF has been successfully treated conservatively by NPO and octreotide. 2 patients required radiological percutaneous transhepatic biliary drainage and 2 patients required surgical drainage of multiple intrabdominal collections and radiological PTBD. CONCLUSION: On the basis of these observations Bioglue® can be safely utilized to coat pancreatic surface after DP and pancreatico-jejunostomy after PD. This experience warrants further larger controlled studies of the potential value of Bioglue® in reducing the incidence of PF after major pancreatic surgery.

Strengthening preparedness against global health threats: A paradigm shift based on One Health approaches.

The implementation of preparedness strategies to prevent and mitigate the impact of global health threats poses several challenges. It should promptly identify cross-cutting drivers of pandemic threats, assess context-specific risks, engage multiple stakeholders, and translate complex data from multiple sources into accessible information for action. This requires a coordinated, multidisciplinary and multisectoral effort engaging systems that, most of the time, work in isolation. The One Health (OH) approach promotes the collaboration and communication among different disciplines and sectors, and could be applied across the preparedness phases at national and international level. We discuss here gaps and needs in preparedness strategies, which can benefit from the OH approach, and a set of actionable recommendations, as shared with the G20-2021 with a dedicated Policy Brief. The discussion adds to the current debate about OH operationalization and promotes a paradigm shift towards coordinated prevention and preparedness strategies for early assessment and management of global health threats.

Syndromic surveillance of epidemic-prone diseases in response to an influx of migrants from North Africa to Italy, May to October 2011.

Following civil unrest in North Africa early in 2011, there was a large influx of migrants in Italy. A syndromic surveillance system was set up in April to monitor the health of this migrant population and respond rapidly to any health emergency. In the first six months, the system produced 67 alerts across all syndromes monitored and four alarms. There were no health emergencies, however, indicating that this migration flow was not associated with an increased risk of communicable disease transmission in Italy.

[Intestinal perforation due to accidental ingestion of foreign bodies]. / Perforazione intestinale da ingestione accidentale di corpo estraneo.

Usually the ingested foreign bodies (IFB) pass the gastrointestinal tract making no lesions. Sometimes IFB could lead to a gastrointestinal perforation. The most frequently perforating IFB are chicken or fish bones and toothpicks, while risks factors are mental retardation, alcohol or drug abuse, denture usage, quick eating or habitual chewing of toothpicks. The accidentally ingestion in a high risk patient with unclear symptoms, added to a low sensitive diagnostic imaging, lead to intraoperative diagnosis in one half cases of gastrointestinal perforation by IFB. Furthermore the surgical treatment range between the less minimal invasive laparoscopic IFB extraction and intraabdominal hole suture to a laparotomic bowel or colic resection. Herein we describe our experience in 3 cases of gastrointestinal perforation by IFB have been diagnosed at surgery and treated by IFB extraction and hole suture (in 2 patients; 1 laparoscopy, 1 laparotomy) or open right emicolectomy (1 patient).

EpiSouth: a network for communicable disease control in the Mediterranean region and the Balkans.

The countries around the Mediterranean Sea share epidemiological characteristics and public health problems. In 2006 the EpiSouth Project was started as a framework for collaboration for communicable diseases surveillance and training in the Mediterranean Basin. As of December 2008, 26 countries from southern Europe, the Balkans, North Africa and the Middle-East are members of EpiSouth and several international organisations and institutions collaborate: the European Commission (EC), the European Centre for Disease Prevention and Control (ECDC), the Italian Ministry of Work, Health and Social Policies and the World Health Organization (WHO). The project is coordinated by the Italian national public health institute and three work packages (WPs) Cross-border epidemic intelligence, vaccine preventable diseases and migrants and Cross-border emerging zoonoses are operated by the national institutes of France, Bulgaria and Greece. These WPs constitute technical pillars on which the project develops. Networking and Training are WPs dedicated to capacity building and are run by the Padua Teaching Hospital (Italy) and the Spanish national public health institute. A steering committee guides EpiSouth's activities while all countries collaborate through WP steering teams and focal points. A number of outcomes have been accomplished and documents with results are available from the EpiSouth website which hosts a public website and a restricted area for direct sharing of information among the participants. Five electronic bulletins were published, two trainings for 63 participants performed, national epidemic intelligence systems were evaluated, a preliminary survey on vaccine-preventable diseases and migrants performed, and a list of priorities for emerging zoonoses in the Mediterranean area was selected. Overall the network succeeded in creating cohesion, mutual trust and concrete collaboration on cross-border public health issues in a geographical area that is not addressed as a whole by any other initiative or organisation.

Heterotopic thyroid tissue is described to usually lie at the tongue base, while the 10% at the hyoid bone. We report a case of incidental diagnosis of a true mediastinal goitre with preoperative chest X-ray in a 35-year old woman with a multinodular cervical goitre.

[Hepatic resections for hepatocarcinoma in the XXI century]. / Le resezioni epatiche per epatocarcinoma nel XXI secolo.

Hepatic resection is today the treatment of choice for cirrhotic patients affected by hepatocellular carcinoma (HCC). Short term results are now definitely satisfactory, with a mortality rate in the referral centers lower than 5%. However, long term results are affected by a high recurrence rate, between 50% and 100%, due to the underlying cirrhosis. Notwithstanding the high recurrence rate, the hepatic resection guarantees a five years survival between 40% and 60%, comparable to the one offered by liver transplantation. The aim of this paper is to review the results of studies on resected cirrhotic patients affected by HCC.

[Bleeding caused by pseudoaneurysm rupture after pancreaticoduodenectomy]. / Emorragia da rottura di pseudoaneurisma post-duodenocefalopancreatectomia.

The Authors describe two cases of delayed hemorrhage due to ruptured gastroduodenal artery pseudoaneurysm, after pancreatoduodenectomy. The first case underwent surgical treatment, the second underwent interventional radiological procedure. The Authors analyze diagnostic and therapeutic options for early diagnosis in high risk patients, supporting preventive treatment of asymptomatic pseudoaneurysms.

HIV, malaria parasites, and acute febrile episodes in Ugandan adults: a case-control study.

BACKGROUND: In sub-Saharan Africa, co-infection with HIV and malaria is probably very common. Although an interaction between the two infections is biologically plausible, it has not been investigated thoroughly. OBJECTIVES: To evaluate the association firstly between co-infection with HIV and malaria parasites and the occurrence of acute fever, and secondly between HIV infection and clinical malaria, defined as the presence of acute fever and malaria parasites. METHODS: A hospital-based case-control study was conducted in Gulu District (northern Uganda), an area endemic for malaria and with a high HIV prevalence. HIV testing and malaria parasite quantification were performed on 167 consecutive adult out-patients with acute fever and no signs or symptoms of localized infection, and on 134 consecutive adult in-patients without fever who were admitted for non-HIV-related trauma or elective surgery. RESULTS: No significant association with acute fever was observed for single infection with either malaria parasites [adjusted odds ratio (AOR), 1.75; 95% confidence interval (CI), 0.73-4.21] or HIV (AOR, 1.01; 95% CI, 0.51-2.03), whereas a significant association was observed for co-infection (AOR, 9.75; 95% CI, 1.19-80.00). An association was found between HIV infection and clinical malaria (AOR, 2.34; 95% CI, 0.89-6.17); the association became statistically significant when the definition of clinical malaria included a cut-off for parasite density (50th percentile; i.e., 586 parasites/microl; AOR, 3.61; 95% CI, 1.04-12.52). CONCLUSIONS: Despite the limited statistical power, the results of our study show an association between HIV infection and clinical malaria; if confirmed, this finding could be important for public health in sub-Saharan Africa.

Impact of insecurity, the AIDS epidemic, and poverty on population health: disease patterns and trends in Northern Uganda.

A retrospective analysis of the discharge records of 186,131 inpatients admitted to six Ugandan hospitals during 1992-1998 was performed to describe the disease patterns and trends among the population of Northern Uganda. In all hospitals, malaria was the leading cause of admission and the frequency of admissions for malaria showed the greatest increase. Other conditions, such as malnutrition and injuries, mainly increased in the sites affected by civil conflict and massive population displacement. Tuberculosis accounted for the highest burden on hospital services (approximately one-fourth of the total bed-days), though it showed a stable trend over time. A stable trend was also observed for acquired immunodeficiency syndrome (AIDS), which is in contrast to the hypothesis that AIDS patients have displaced other patients in recent years. In conclusion, preventable and/or treatable communicable diseases, mainly those related to poverty and poor hygiene, represent the leading causes of admission and death, reflecting the socioeconomic disruption in Northern Uganda.

Marginal adaptation of crowns: a scanning electron microscopic investigation.

Most studies on marginal adaptation have been performed in vitro; only a few studies have investigated in vivo marginal adaptation and microleakage of crowns. In this study, gold crowns were prepared and cemented on abutments, and their marginal discrepancies were analyzed by scanning electron microscopy according to the impression-replica and cross-section methods. Three observers measured the marginal discrepancies of each crown. Interobserver variance of accuracy was 10 microns by the impression-replica and 15 microns by the cross-section method. The mean values were 124.16 microns by the impression-replica and 129.79 microns by the cross-section method. The two methods tested showed similar results.

Laparoscopic dual mesh repair of a diaphragmatic hernia of Bochdalek in a symptomatic elderly patient.

Bochdalek hernia is a congenital posterolateral diaphragmatic defect. It is usually diagnosed in newborns and children; the mortality rate is high due to further congenital anomalies such as pulmonary hypoplasia and pulmonary hypertension. In adulthood, the diagnosis is often incidental, while sometimes it is related to gastrointestinal or respiratory symptoms, or to herniated viscera complications. Thus, surgical treatment is advocated. We herein report a case of an 86-year-old woman with dyspnea and dysphagia. After the diagnosis by barium enema and CT scan of the herniated stomach and the greater omentum through a left side foramen of Bochdalek, she underwent a successful laparoscopic dual mesh repair and was discharged on the 6th postoperative day.

Prospective validation of a proposal for diagnosis and management of patients attending the emergency department for mild head injury.

BACKGROUND: In mild head injury, predictors to select patients for computed tomography (CT) and/or to plan proper management are needed. The strength of evidence of published recommendations is insufficient for current use. We assessed the diagnostic accuracy and the clinical validity of the proposal of the Neurotraumatology Committee of the World Federation of Neurosurgical Societies on mild head injury from an emergency department perspective. METHODS: In a three year period, 5578 adolescent and adult subjects were prospectively recruited and managed according to the proposed protocol. Outcome measures were: (a) any post-traumatic lesion; (b) need for neurosurgical intervention; (c) unfavourable outcome (death, permanent vegetative state or severe disability) after six months. The predictive value of a model based on five variables (Glasgow coma score, clinical findings, risk factors, neurological deficits, and skull fracture) was tested by logistic regression analysis. FINDINGS: At first CT evaluation 327 patients (5.9%) had intracranial post-traumatic lesions. In 16 cases (0.3%) previously undiagnosed lesions were detected after re-evaluation within seven days. Neurosurgical intervention was needed in 71 patients (1.3%) and an unfavourable outcome occurred in 39 cases (0.7%). The area under the ROC curve of the variables in predicting post-traumatic lesions was 0.906 (0.009) (sensitivity 70.0%, specificity 94.1% at best cut off), neurosurgical intervention was 0.926 (0.016) (sensitivity 81.7%, specificity 94.1%), and unfavourable outcome was 0.953 (0.014) (sensitivity 88.1%, specificity 95.1%). INTERPRETATION: The variables prove highly accurate in the prediction of clinically meaningful outcomes, when applied to a consecutive set of patients with mild head injury in the clinical setting of a 1st level emergency department.

Early gastric cancer: prognostic factors in 223 patients.

A retrospective study of 223 patients treated for early gastric cancer (EGC) is reported, representing 21.2 per cent of the 1051 patients with gastric cancer treated over the same period. Two main types of surgical procedure were used: subtotal resection of the stomach for EGC of the two lower thirds and total gastrectomy for lesions of the upper third. A lymphadenectomy of groups 1 and 2, according to the procedure of the Japanese Research Society for Gastric Cancer (R2 resection), was performed in all patients. The mean duration of follow-up was 7.5 years. Univariate analysis showed a significant difference in survival rates only between patients with and without involved nodes (log rank = 6.05, P = 0.0139). Other prognostic factors were not identified. A bivariate analysis was performed to evaluate the joint effect of node status and the Kodama classification: survival rates for patients with EGC of the penetrating (Pen) A type and node positive falls to around 57 per cent within 6 years. This group of patients has a tumour that should probably be considered as a 'non-early' lesion. To improve the survival of patients with a Pen A, node positive lesion, adjuvant chemotherapy may be appropriate.

Blood alcohol concentration and management of road trauma patients in the emergency department.

BACKGROUND: The effects of blood alcohol on injury after crash are controversial, and safe limits are not settled. We examined if a positive blood alcohol concentration, even in a nontoxic range, affects management and outcome of injured patients after road crashes. METHODS: In this prospective cohort study, we recruited all adult subjects admitted to an emergency department within 4 hours after a road crash. Outcomes were mortality or expected permanent disability, and data related to patients' management. RESULTS: Alcohol-positive trauma patients were more frequently critical at admission (odds ratio [OR], 1.89; 95% confidence interval [CI], 1.18-3.02), and had an increased risk of combined mortality or expected permanent disability (OR, 1.67; 95% CI, 1.08-2.58), need for intensive care (OR, 1.87; 95% CI, 1.01-3.46), surgery (OR, 1.91; 95% CI, 1.37-2.66) and blood transfusions (OR, 2.09; 95% CI, 1.20-3.64), and acute medical complications (OR, 1.94; 95% CI, 1.33-2.85). All these events were explained by higher trauma severity. Only the risk of unsuspected injuries, diagnosed only at final evaluation, was independently associated with a positive blood alcohol concentration (OR, 4.98; 95% CI, 3.62-6.87), in addition to trauma severity and preexisting chronic conditions. Blood alcohol measurement significantly improved the accuracy in predicting unsuspected injuries, from 81.3% to 86.2%. CONCLUSION: In injured patients after a road crash, a positive blood alcohol concentration increases the chance that the final diagnosis will include more injuries than initially documented. More careful monitoring is needed in alcohol-positive trauma patients, independent of clinical status, injury severity, and overt symptoms of alcohol intoxication.

Positive blood alcohol concentration and road accidents. A prospective study in an Italian emergency department.

STUDY OBJECTIVE: To examine if a positive blood alcohol concentration (BAC) at the time of crash (>or=0.50 g/l), independently of any clinical evidence and laboratory results indicating acute alcohol intoxication, is associated with specific features of patients involved, specific types of injury, and characteristics of the accident. METHODS: In this prospective cohort study, the BAC was measured in adult patients who had been injured and who were admitted to an Italian emergency department within four hours after a road accident. Altogether 2354 trauma patients were included between January to December 1998 out of 2856 eligible subjects. RESULTS: BAC exceeded 0.50 g/l in 425 subjects (18.1%), but was in a toxic range (>1.00 g/l) in only 179 subjects (7.6%). BAC positivity was significantly more common in men, in young subjects, in subjects driving cars or trucks, and in persons involved in a crash during night time and at weekends. It was associated with higher trauma severity, but no differences were found in injury body distribution according to vehicle type. In multivariate logistic regression analysis, the risk of a positive BAC in injured patients at the time of crash was independently associated with night time (odds ratio: 3.48; 95% confidence intervals: 2.46 to 4.91), male sex (3.08 (2.36 to 4.01)), weekend nights (1.21 (1.05 to 1.41)), and age (0.92 (0.86 to 0.99) per decades). CONCLUSION: In injured patients after a road accident, a BAC at the time of crash in a non-toxic range (>or=0.50 g/l) is associated with specific characteristics of crash, as well as increased risk of higher trauma severity. More careful monitoring is needed in young men during weekend nights for highest risk of BAC positivity after a road accident.
