Abstract
BACKGROUND Previous studies showed that bacterial contamination of surgical drains was associated with higher morbidity and mortality following pancreaticoduodenectomy (PD). However, there is still no agreement on the routine use of fluid drainage cultures in the management of patients underwent PD. Therefore, we aimed to clarify the role of surgical drain bacterial contamination in predicting patients' postoperative course. METHOD Single-centre study including patients underwent PD at Humanitas Research Hospital (2010-2021). Preoperative, intraoperative and postoperative data were collected. Routinely performed fluid drain cultures on postoperative day (POD) 5 were analyzed and compared among patients throughout the cohort. RESULTS A total of 825 patients were analyzed. Bacterial contamination of surgical drains was observed in 420 (50.9 %) patients and it was found to be associated with a higher rate of B/C grade pancreatic fistula (POPF) (P < 0.001), Clavien-Dindo≥3 (P < 0.001), 30-day mortality (P = 0.011), wound infection (P < 0.001), relaparotomies (P = 0.003) and greater length of hospital stay (LOS) (P < 0.001). Also, E. coli surgical drain contamination was demonstrated to double the risk of B/C grade POPF development (OR = 1.628, 95 % IC = 1.009-2.625, P = 0.046). Finally, preoperative biliary drainage (OR = 2.474, 95 % IC = 1.855-3.298, P < 0.001), age ≥75 years old (OR = 1.492, 95 % IC = 1.077-2.067, P = 0.016) and isolated Roux-en-Y pancreaticojejunostomy (OR = 1.639, 95 % IC = 1.229-2.188, P < 0.001) were identified as risk factors for surgical drains bacterial contamination. CONCLUSION Bacterial contamination of surgical drains predicts the development of B/C grade POPF and other major complications after PD. Therefore, we suggest the routine use of fluid drain cultures following PD.

Abstract
BACKGROUND Laparoscopic lavage was proposed in the 1990s to treat purulent peritonitis in patients with perforated acute diverticulitis. Prospective randomized trials had mixed results. The aim of this study was to determine the success rate of laparoscopic lavage in sepsis control and to identify a group of patients that could potentially benefit from this treatment. METHODS This retrospective multicentre international study included consecutive patients from 24 centres who underwent laparoscopic lavage from 2005 to 2015. RESULTS A total of 404 patients were included, 231 of whom had Hinchey III acute diverticulitis. Sepsis control was achieved in 172 patients (74·5 per cent), and was associated with lower Mannheim Peritonitis Index score and ASA grade, no evidence of free perforation, absence of extensive adhesiolysis and previous episodes of diverticulitis. The operation was immediately converted to open surgery in 19 patients. Among 212 patients who underwent laparoscopic lavage, the morbidity rate was 33·0 per cent; the reoperation rate was 13·7 per cent and the 30-day mortality rate 1·9 per cent. Twenty-one patients required readmission for early complications, of whom 11 underwent further surgery and one died. Of the 172 patients discharged uneventfully after laparoscopic lavage, a recurrent episode of acute diverticulitis was registered in 46 (26·7 per cent), at a mean of 11 (range 2-108) months. Relapse was associated with younger age, female sex and previous episodes of acute diverticulitis. CONCLUSION Laparoscopic lavage showed a high rate of successful sepsis control in selected patients with perforated Hinchey III acute diverticulitis affected by peritonitis, with low rates of operative mortality, reoperation and stoma formation.

Abstract
BACKGROUND The aim of the work presented was to assess job satisfaction of a number of nurses from different departments working in public hospitals in Italy. The assessment was carried out through the combined use of questionnaires, which measured different aspects of job satisfaction, such as coping abilities, stress level and optimism/pessimism. The literature supports the fact that nurses' job dissatisfaction is closely connected with high levels of stress, burnout and physical and mental exhaustion, together with high workload levels and the complexity of care. The growing interest in measuring the levels of nurses' job satisfaction is attributable to a number of problems that have been raised worldwide, two of which are becoming ever so important: turnover and shortage of nurses. The research question is: Which are the main motivating factors of Italian nurses' job satisfaction/dissatisfaction? METHODS The study used a convenience (non probability) sample of 1,304 nurses from 15 different wards working in Italian public hospitals from a number of cities in northern, central and southern Italy. The survey instrument was a questionnaire consisting of 205 items which included 5 different questionnaires combined together. RESULTS The results show a low level of job satisfaction (IWS= 11.5, JSS=126.4). However, the participants were overall happy about their job and considered autonomy and salary important factors for job satisfaction. CONCLUSION Research has shown that the nurses' level of satisfaction in Italian hospitals is low. The results revealed dissatisfaction with task requirements, organizational policies and advance in career. Nurses interviewed did not feel stressed and showed to be optimistic overall. New research on the subject should be conducted by focusing on ward differences, North and South of Italy and on gender differences.

Abstract
BACKGROUND The ideal treatment of perforated diverticulitis and the indications for elective colon resection remain controversial. Considering the significant morbidity and mortality rates related to traditional resection, efforts have been made to reduce the invasiveness of surgery in recent decades. Laparoscopic peritoneal lavage has emerged as an effective alternative option. We retrospectively investigated the effectiveness of laparoscopic peritoneal lavage for perforated diverticulitis and the possibility that it could be a definitive treatment. METHODS We included patients treated with laparoscopic peritoneal lavage for perforated diverticulitis. The inclusion criteria were all emergency patients with generalized peritonitis due to Hinchey III perforated diverticulitis and some cases of Hinchey II and IV. RESULTS Sixty-three patients were treated with laparoscopic peritoneal lavage. Six patients (9.5 %) had Hinchey II diverticulitis; 54 patients (85.7 %) had Hinchey III; and three patients (4.8 %) had Hinchey IV. The mean operative time was 87.3 min (±25.4 min), and the overall morbidity rate was 14.3 %. One patient died because of pulmonary embolism, and there were six early reinterventions because of treatment failure. Delayed colon resection was performed in four of the remaining 57 patients (7 %) because of recurrent diverticulitis. In the other 53 patients (93 %), we saw no recurrence of diverticulitis and no intervention was performed after a median follow-up period of 54 months (interquartile range 27-98 months). CONCLUSIONS Laparoscopic peritoneal lavage for perforated diverticulitis can be considered a safe and effective alternative to traditional surgical resection, and using this approach, most elective colon resection might be avoided.

Abstract
OBJECTIVES To review the normal and pathological development of the posterior membranous area (PMA) in the fetal brain, to define sonographic criteria with which to diagnose a Blake's pouch cyst (BPC) in the fetus and to review the ultrasound features, associations and outcome of 19 cases of BPC seen at our center over the last 5 years. METHODS We conducted a MEDLINE search using the terms 'Blake's pouch', with or without 'fourth ventricle' or '4(th) ventricle', with or without 'roof' and identified articles describing normal and/or abnormal development of the PMA, whether or not they were cited in the limited clinical literature on BPC. A description of the normal and abnormal development of BPC was derived by collating these articles. The clinical retrospective study included 19 cases of posterior fossa anomalies with a final diagnosis of BPC seen at our institution. The following variables were assessed: referral indication, gestational age at diagnosis, ultrasound and magnetic resonance imaging (MRI) findings, associated anomalies, natural history and pregnancy and neonatal outcome. A transvaginal three-dimensional (3D) ultrasound examination was performed in all cases and 15 cases underwent MRI. To confirm the diagnosis, postnatal MRI, transfontanellar ultrasound or autopsy were available in all cases. RESULTS Among the 19 cases reviewed, referral indications were: suspicion of vermian abnormality in 11 (58%) cases and other non-central nervous system anomaly in eight (42%) cases. Sonographically, all cases showed the following three signs: 1) normal anatomy and size of the vermis; 2) mild/moderate anti-clockwise rotation of the vermis; 3) normal size of the cisterna magna. On 3D ultrasound, the upper wall of the cyst was clearly visible in 11/19 cases, with choroid plexuses on the superolateral margin of the cyst roof. On follow-up, the BPC had disappeared by 24-26 gestational weeks in six of the 11 cases which did not undergo termination of pregnancy (TOP), and remained unaltered until birth in the other five cases. There were associated anomalies in eight (42%) cases, in five of which this consisted of or included congenital heart disease. Karyotype was available in 14 cases, two of which were abnormal (both trisomy 21). Regarding pregnancy outcome, there were eight (42%) TOPs, two (10%) neonatal deaths and nine (48%) survivors. One neonate, in whom the BPC had disappeared by the time of birth, had obstructive hydrocephaly confirmed. Another neonate was diagnosed with Down syndrome after birth. Excluding the Down syndrome baby, neurodevelopmental outcome was normal at the time of writing in all eight cases. CONCLUSIONS Based on our analysis of ultrasound features, we propose that for BPC to be diagnosed in a fetus the following three criteria should be fulfilled: 1) normal anatomy and size of the vermis; 2) mild/moderate anti-clockwise rotation of the vermis; 3) normal size of the cisterna magna. Furthermore, we found that BPC can undergo delayed fenestration at 24-26 weeks in more than 50% of cases. Finally, it seems that BPC shows a risk of association with extracardiac anomalies (heart defects in particular) and, to a lesser extent, trisomy 21.

Abstract
The aim of this study was to evaluate the efficacy and safety of risedronate and pamidronate in 30 patients (mean age = 57.86 +/- 8.90 years) with severe Paget's disease of bone (PDB), showing acquired resistance to intravenous (IV) clodronate treatment. Fifteen patients were treated with oral risedronate (30 mg/day for 8 weeks). Treatment was repeated in patients without evidence of PDB remission [total alkaline phosphatase (tALP) serum levels in the normal range] at day 120. Fifteen patients were treated with IV pamidronate (30 mg/day for 3 days). Pamidronate treatment (60 mg/day for 3 days) was repeated in patients without evidence of PDB remission at day 120. At day 60, a significant decrease in tALP serum levels was obtained in all pagetic patients. At day 360, 13 (86.6%) patients treated with risedronate achieved PDB remission, 9 patients during the initial treatment and 4 after retreatment. Two patients showed a significant decrease in tALP serum levels without clinical remission after two risedronate treatments. At the same time, 12 (80%) patients treated with pamidronate achieved PDB remission, 6 patients during the first treatment and 6 after retreatment. Three patients showed a significant decrease in tALP serum levels but no clinical remission after two pamidronate courses. Two of these patients showed a relapse during the study. The incidence of minor side effects and transient hyperparathyroidism related to bisphosphonate treatment was significantly lower after risedronate therapy. In patients with resistant PDB, oral risedronate therapy has comparable efficacy to IV pamidronate with a lower incidence of treatment-related side effects.

Abstract
OBJECTIVES The purpose of this study was to compare the results of physical examinations (PEs) performed by board-certified cardiologists with the results of point-of-care (POC) echocardiography in a group of patients with cardiovascular disease. BACKGROUND Although cardiovascular PE is crucial in the evaluation of patients with suspected heart disease, the skills required to diagnose abnormal cardiovascular findings have been declining. Echocardiography is a powerful noninvasive cardiovascular diagnostic tool; however, echocardiographic evaluation of patients is not performed at the time of patient encounter (POC echocardiography), beacuse current platforms are cumbersome and expensive for individual physician use. The development of miniaturized echocardiographic equipment has the potential to overcome some of these limitations. METHODS Thirty-six subjects had a complete cardiovascular examination by four board-certified cardiologists. The physicians subsequently imaged each patient using a miniaturized echocardiographic platform. The yield of PE and POC echocardiography were compared using a complete echocardiographic study as the gold standard, performed on an upper-end platform. RESULTS Cardiac examination failed to detect 59% of the overall cardiovascular findings. Physician-performed echocardiography with the prototype device missed 29% of the overall cardiovascular pathology. When considering only the major cardiovascular findings, the cardiologists' PEs still failed to correctly detect 43%. Point-of-care echocardiography reduced this to 21% without significant interphysician variation. CONCLUSIONS Point-of-care echocardiography using a miniaturized echocardiographic platform substantially improved the detection of important cardiovascular pathology compared with PE. Use of this device by a cardiovascular specialist with training in echocardiography as a routine adjunct to PE appears to be useful.

Abstract
In patients with non-obstructive azoospermia, testicular sperm extraction (TESE) is a method of choice to recover spermatozoa as a male therapeutic approach in intracytoplasmic sperm injection (ICSI) programmes. However, the efficacy of TESE in this indication is burdened by a frequent failure of sperm recovery, which renders useless both the invasive testicular intervention and ovarian stimulation of the patient's spouse. One of the most frequent pathological pictures characterizing complete absence of spermatozoa is germinal aplasia (Sertoli cell- only syndrome or SCOS). Two different histological patterns of SCOS have been already described during the past five decades. These two patterns can be characterized as the congenital (pure) and the secondary (mixed) forms. Both patterns, with different prognosis to retrieve spermatozoa by therapeutic testicular biopsy, are frequently confused when TESE is performed during ICSI programmes. Useful criteria to predict the absence of spermatozoa can be obtained by a definite recognition of the two typical histological patterns during the diagnostic testicular biopsy. The diagnosis of congenital or acquired SCOS can be refined by endocrine, chemical, immunohistochemical and molecular biology aids. Reduction of both sperm retrieval failure and unnecessary ovarian stimulation can be achieved by combination of these methods.

Abstract
BACKGROUND Respiratory syncytial virus (RSV) remains a significant cause of morbidity, especially in premature infants and immunocompromised children, resulting in approximately 100 000 hospitalizations annually. A study was performed to evaluate the outcomes of those given palivizumab (Synagis; MedImmune, Inc., Gaithersburg, MD) during the 1998 to 1999 RSV season, its first season in general use. METHODS A retrospective chart review of 1839 patients from 9 United States sites was conducted, representing all patients given palivizumab at each site. Those evaluated were to have a gestational age of < or =35 weeks, were to be <2 years old at their first injection and were to have received at least one dose of palivizumab (humanized monoclonal antibody against RSV) between September, 1998, and May, 1999. Gestational age, comorbidities, frequency of injections, hospitalizations and length of hospital stays were assessed. RESULTS The antigen- or culture-positive RSV hospitalization rates for those given prophylaxis were 2.3% (42 of 1839) overall, 16/399 (4.0%) with chronic lung disease of infancy and 26 of 1227 (2.1%) born prematurely without chronic lung disease of infancy. Twenty-six patients had a gestational age of >35 weeks and were included in the analysis. CONCLUSIONS Only 2.3% of children receiving palivizumab prophylaxis were hospitalized with RSV lower respiratory infection. This compares favorably with the rates observed in the pivotal trial (IMpact-RSV trial in 1996 to 1997), in which prophylaxis reduced hospitalization from 10.6% in the placebo group to 4.8% in those children receiving prophylaxis.

Abstract
Ascidian and vertebrate nervous systems share basic characteristics, such as their origin from a neural plate, a tripartite regionalization of the brain, and the expression of similar genes during development. In ascidians, the larval chordate-like nervous system regresses during metamorphosis, and the adult's neural complex, composed of the cerebral ganglion and the associated neural gland is formed. Classically, the homology of the neural gland with the vertebrate hypophysis has long been debated. We show that in the colonial ascidian Botryllus schlosseri, the primordium of the neural complex consists of the ectodermal neurohypophysial duct, which forms from the left side of the anterior end of the embryonal neural tube. The duct contacts and fuses with the ciliated duct rudiment, a pharyngeal dorsal evagination whose cells exhibit ectodermic markers being covered by a tunic. The neurohypophysial duct then differentiates into the neural gland rudiment whereas its ventral wall begins to proliferate pioneer nerve cells which migrate and converge to make up the cerebral ganglion. The most posterior part of the neural gland differentiates into the dorsal organ, homologous to the dorsal strand. Neurogenetic mechanisms in embryogenesis and vegetative reproduction of B. schlosseri are compared, and the possible homology of the neurohypophysial duct with the olfactory/adenohypophysial/hypothalamic placodes of vertebrates is discussed. In particular, the evidence that neurohypophysial duct cells are able to delaminate and migrate as neuronal cells suggests that the common ancestor of all chordates possessed the precursor of vertebrate neural crest/placode cells.

Abstract
The authors report their experience about laparoscopic surgery in the treatment of adrenal tumours. Three laparoscopic right adrenalectomies were performed. From a comparison with five open adrenalectomies, microinvasive surgery is more advantageous than traditional management: recovery is earlier, incisions are smaller, post-operative discomfort is less, physiologic functions recover in a short time, return to full professional activity in one week.

Abstract
The solid papillary tumor of the pancreas is a relative rare neoplasm that often is unknown because of its diagnostic difficulties. It is frequent in young women. It has no typical clinical signs, sometimes produces abdominal mass, sometimes is found casually during investigations for other diseases. Instead the prognosis of this tumor is more typical: long-term survival is good. The natural history of the solid papillary is the same as neoplasm with a low malignancy potential. For this reason, it's important to make up a differential diagnosis between it and the other pancreatic tumors. Unlike the other malignancies, surgical conservative therapy is enough without making great demolitions of the pancreas. Lumpectomy gives a complete cure, decreasing surgical risk and dangerous functional complications. In the present paper, a case of solid papillary tumour of the pancreas is reported. It was diagnosed in a young woman and treated with simple lumpectomy. She is alive and disease free.

Abstract
A rare case of hemoperitoneum in a young man who performed a diagnostic colonoscopy is reported. The rupture of an epiploic appendix among rectum and colon sigma caused massive bleeding into the peritoneum cavity followed by haemorrhagic shock. Diagnostic and therapeutic colonoscopy has a low rate of morbility; perforation and bleeding are the most common events; hemoperitoneum following colonscopy is usually due to spleen rupture. Among other complications, ileal and cecal volvolus, incarceration of hernias and subcutaneous emphysema are reported.

Abstract
This randomized double-blind placebo-controlled study was designed to evaluate the effects on postoperative pain of the local anesthetic, 0.5% bupivacaine with epinephrine, sprayed hepatodiaphragmatically under the surgeon's direct view during laparoscopic cholecystectomy. Metabolic endocrine responses to surgery (glucose and cortisol) and nonsteroidal anti-inflammatory drug requirements were investigated, as well as the presence of nausea, vomiting, and sweating. Local anesthetics or placebo solutions were given as follows. Immediately following the creation of a pneumoperitoneum, surgeons sprayed the first 20 mL of solution (S1), and an additional 20 mL of solution (S2) was sprayed at the end of the operation. Patients were classified into three groups (14 patients per group). Group A received 20 mL of saline during both S1 and S2, group B received 20 mL of saline during S1 and 20 mL of bupivacaine during S2, and group C received 20 mL of bupivacaine during both S1 and S2. The degree of postoperative pain was assessed using the visual analogue scale (VAS) and the verbal rating scale (VRS) on arrival in the recovery room and subsequently at time intervals of 4 h, 8 h, 12 h, and 24 h. The results of this study indicate a significant decrease of postoperative pain in patients treated with local anesthetic. VAS and VRS pain scores, as well as respiratory rate and analgesic requirements, were significantly lower in group C. The postoperative plasma cortisol level in group C was significantly lower than in groups A and B.

Abstract
By restoring the balance between myocardial oxygen supply and demand, intra-aortic balloon counterpulsation can aid the ischemic or failing left ventricle. Rapid inflation and deflation of the balloon reduces afterload and improves coronary perfusion. Timing of inflation and deflation is adjusted according to the arterial pressure waveform. The balloon should inflate just after the aortic valve closes and deflate just before the aortic valve opens; early or late balloon inflation or deflation blunts the therapeutic effects. Discontinue the IABP support gradually; monitor the patient frequently for any signs of hemodynamic compromise, redevelopment of ischemic chest pain, or electrocardiographic changes.

Abstract
A case of positionally symptomatic right-to-left shunting across a patent foramen ovale with both platypnea and orthodeoxia despite normal pulmonary arterial pressures and normal right ventricular function is documented. When the patient was in a supine position, the calculated right-to-left shunt was 12.8 percent, and when seated 25 percent. Surgical closure of the patent foramen ovale relieved the symptoms and positionally induced shunting. The prevalence and associations of permanent and intermittent patency of the foramen ovale are discussed. It is recommended that those at risk of thromboembolism be screened for patency by contrast ultrasound or color flow techniques. If present, surgical closure needs to be considered to prevent paradoximal embolism and stroke.

Abstract
The major aspects of the antithrombogenic and antiatherogenic effects of polyunsaturated fatty acids (PUFA) have been outlined. After briefly relating on the biochemistry, the essentiality concept has been defined. Some of the many evidences of their effects both on men and animals have been reported. Eicosanoid metabolism is discussed and eicosanoid compounds derived from omega-6 and omega-3 fatty acids are compared with regard to their effects concerning atherosclerosis. Considerations about the correct amount of PUFA are reported as tentative strategies for a cardiovascular protective diet.

Abstract
Longitudinal observation of fasting triglyceride and total cholesterol levels throughout gestation in 16 type I, 13 type II, 11 GDM and 14 normal pregnant women was made. There were no significant differences between the groups examined, except the higher levels of triglycerides in GDM group during the second trimester (p less than 0.05). Probably these results are due to "good" metabolic compensation, achieved in diabetic pregnant women.

Abstract
Using immunohistochemical methods, we have determined the cellular localization of the enzymes, glutamine synthetase (GS) and carbonic anhydrase-C (CA-C), in mouse neural retina during development and in the mature tissue. GS is always confined exclusively to the Müller glial cells; it is first detectable in these cells post-natally on about day 12, i.e. shortly before the eyes open. Also CA-C in the mature retina is localized in the Müller cells but, in addition, it is found in certain amacrine neurons as well. CA-C is first detectable in the retina already several days before birth; at that time it is found in most of the cells, with the exception of the emerging ganglion cells. However, with advancing differentiation, CA-C becomes progressively restricted to Müller cells and to a sub-category of amacrine neurons, and persists only in these cells in the mature retina. The present results extend our previous studies on these enzymes in the avian retina; they demonstrate that also in mammalian retina, different temporal and cellular patterns of GS and CA-C expression and localization earmark distinct phases of structural and functional differentiation of the retina. The striking developmental changes in the cellular localization of CA-C, and the finding of this enzyme in certain amacrine neurons as well as in Müller cells, raise questions about the role of CA-C in the retina, and about mechanisms regulating its expression in specific cell types.
