Acute appendicitis in elderly during Covid-19 pandemic.

PURPOSE: During the past months, the Italian Government has reduced the restrictions and access to hospitals. Since then, up to 40% of non-traumatic abdominal emergencies have had unusual delayed treatment. Given the rapidly evolving situation and the absence of evidence to support recommendations during the pandemic, it is useful to assess how the current situation is influencing the management of elderly with acute appendicitis. METHODS: Between February 2020 and December 2020, all patients older than 68 years old undergone appendectomy were included. Surgical approach, hospital stay, post-operative complications, radiology reports, and histologic examination were included in the retrospective analysis and compared with a same sample of the same period before the pandemic. RESULTS: Twenty-seven patients underwent appendectomy for acute appendicitis during the pandemic and 34 patients in the pre-outbreak period. Laparoscopic approach was completed in 51.8% of the cases, while conversion to laparotomy in 22.3% of patients and open procedure in the 25.9%, before the pandemic 73.6%, 14.7%, and 11.7%, respectively. During the pandemic, complicated appendicitis occurred in 59.3% of the cases (26.5% before the outbreak). One patient was treated for a pelvic abscess, while no minor complications were detected. No mortality rate was reported, with a mean hospital stay of 5.64 days during the outbreak and 4.21 days before the pandemic. CONCLUSION: Our data highlighted a partial delay in diagnosis in the elderly group, and an increase in complicated appendicitis also demonstrated by the need for conversion to laparotomy.

Lift and VAAFT for high trans-sphincteric anal fistula: a single center retrospective analysis.

PURPOSE: The management of complex anal fistulas remains a challenge, mainly due to the considerable risk of incontinence. We compared LIFT and VAAFT in the treatment of complex anal fistulas in terms of healing time, recurrence, continence, morbidity, and postoperative pain, focusing also on patients with local abscess at the time of surgery. METHODS: We include all patients with high trans-sphincteric anal fistula even with abscess at the time of surgery. Anorectal manometry, endoanal ultrasound, Cleveland Clinic fecal incontinence score, VAS score, and number of previous fistula treatment were recorded. The clinical examination defined healing, insufficiency or recurrence of the fistula. RESULTS: Fifty-four consecutive patients are undergoing surgery: 26 patients underwent LIFT and 28 underwent VAAFT. During the 18 months of follow-up there were no differences in terms of AM, CCFIS and VAS scores. Days of healing, failure, and recurrence rate were comparable in both groups. The subgroup of patients with local abscess undergoing LIFT showed worse results in terms of failure and recurrence rate (p < 0.05). CONCLUSIONS: Both techniques are safe and effective and can offer long-term benefits. LIFT should not be used as a first treatment in high trans-sphincteric fistula with perianal abscess.

Sphinkeeper™ for faecal incontinence: a preliminary report.

AIM: A new artificial anal sphincter placed into the intersphincteric space, SphinKeeper™, has recently been proposed to improve outcomes in the treatment of faecal incontinence (FI). We report our preliminary results with short-term follow-up, comparing preoperative and postoperative data after implant of SphinKeeper™ in patients suffering from FI. METHODS: All patients older than 18 years were included with FI of at least 6 months, incontinence episodes occurring more than once a week and resistance to other conservative treatments. Anorectal manometry, endoanal ultrasound, Cleveland Clinic FI Score, FI Quality of Life score and total number of episodes of FI per week were recorded preoperatively and at the end of the 6-month follow-up period. RESULTS: Thirteen consecutive patients were treated with SphinKeeper™. No intra-operative nor postoperative complications were reported. Two cases of prosthesis extrusion occurred, and in one case an anterior dislocation was detected. Maximum resting pressure, total number of episodes of FI per week and Cleveland Clinic FI Score were improved after 6 months (P < 0.05). CONCLUSIONS: SphinKeeper™ could be a minimally invasive procedure for FI with good postoperative outcomes. If these results are confirmed by studies with more patients and longer follow-up, it could be a first-line approach in FI.

Complex anal fistula remains a challenge for colorectal surgeon.

AIM: Anal fistula is a common proctological problem to both patient and physician throughout surgical history. Several surgical and sphincter-sparing approaches have been described for the management of fistula-in-ano, aimed to minimize the recurrence and to preserve the continence. We aimed to systematically review the available studies relating to the surgical management of anal fistulas. MATERIAL AND METHODS: A Medline search was performed using the PubMed, Ovid, Embase, and Cochrane databases to identify articles reporting on fistula-in-ano management, aimed to find out the current techniques available, the new technologies, and their effectiveness in order to delineate a gold standard treatment algorithm. RESULTS: The management of low anal fistulas is usually straightforward, given that fistulotomy is quite effective, and if the fistula has been properly evaluated, continence disturbance is minimal. On the contrary, high complex fistulas are challenging, because cure and continence are directly competing priorities. CONCLUSIONS: Conventional fistula surgery techniques have their place, but new technologies such as fibrin glues, dermal collagen injection, the anal fistula plugs, and stem cell injection offer alternative approaches whose long-term efficacy needs to be further clarified in large long-term randomized trials.

A critical review and meta-analysis of the perceptual pseudoneglect across psychiatric disorders: is there a continuum?

The phenomenon known as "perceptual pseudoneglect" refers to the leftward bias in visuospatial attention in non-clinical samples, possibly as a consequence of right hemisphere dominance for visuospatial attention. The degree of such a lateralized visuospatial attention bias is often assessed using the line bisection task. Interestingly, various psychiatric disorders may influence the expression of this phenomenon. The aim of this paper was to perform a critical appraisal of the literature on the expression of the perceptual pseudoneglect across all psychiatric disorders accompanied by meta-analytical evaluation of the data. Moreover, we will discuss whether this phenomenon may be considered as a trait marker across different psychiatric disorders.

A Structured Training for Trans Anal Irrigation in Pediatric Patients Improves Outcomes and Reduce Failures: Results of an Interventional Multicenter Prospective Study.

BACKGROUND: Continence issues due to organic causes including previous colorectal surgery or neurological issues might benefit from Transanal irrigation (TAI) that proved to be highly effective but with a number of limitations including a relatively high discontinuation rates. Our study was aimed at evaluating the efficacy of an advanced protocol tailored to each patient to prevent dropout and increase satisfaction, independence, and quality of life. MATERIALS AND METHODS: This was a prospective, interventional, multicenter, nonrandomized study involving children aged 4-18 years with bowel dysfunction unresponsive to conventional treatments who required TAI. TAI was performed in accordance to the best standards of care with a total irrigation volume that was determined based on low emission X-Ray barium enemas performed at the very beginning of the study. All patients underwent training and assessments of continence, patients' perspectives and quality of life were performed at different timepoints from enrollment (T0) up to 6 months since TAI was introduced (T3). RESULTS: A total of 78 patients were enrolled. Male to female ratio was 1.4:1. Mean age at enrollment was 106.1 ± 42.8 months. Discontinuation was reported by 3 patients (3.8 %). Continence, satisfaction and a number of other outcome measures increased from baseline (T0) to the last visit (T3). In particular, mean Rintala total score increased linearly from 7.8 to 14.8 during the study period (T0 to T3 timepoints). On a multivariate analysis, the only parameter that proved to be inversely associated with continence as well as with other outcome measures was the use of laxatives at enrollment and during the study. CONCLUSIONS: This study has demonstrated the high efficacy of this innovative patient-tailored TAI protocol across all assessed scores. Of note, given the negative impact of laxatives, our findings suggest limiting their use in this patient population to further increase the efficacy of the procedure.

Invasive meningococcal disease in Italy: from analysis of national data to an evidence-based vaccination strategy.

INTRODUCTION: Invasive meningococcal disease (IMD) is one of the most severe vaccine-preventable disease not yet under control. In Italy, although different anti-meningococcal vaccines are available, their offer among regions is heterogeneous. The aim of this study is to describe the epidemiology of IMD in Italy based on analysis of national surveillance data for 2011-2017 to optimize the vaccination strategy. METHODS: IMD surveillance data from the Italian National Health Institute were analysed. Microsoft Excel was used to present trend analysis, stratifying by age and serogroups. RESULTS: In Italy, during the period 2011-2017, the incidence of IMD increased from 0.25 cases/100,000 inhabitants in 2011 to 0.33 cases/100,000 in 2017. Most cases after 2012 were caused by non-B serogroups. The number of cases in subjects aged 25-64 years increased steadily after 2012 (36 cases in 2011, 79 in 2017), mostly due to non-B serogroups, representing more than 65% of cases in those aged 25+ years. CONCLUSIONS: In the period from 2011 to 2017, the incidence of IMDs increased in Italy. The increase, probably due also to a better surveillance, highlights the importance of the disease in the adult population and the high level of circulation of non-B serogroups in particular after 2012. Our analysis supports an anti-meningococcal vaccination plan in Italy that should include the highest number of preventable serogroups and be aimed at vaccinating a wider population through a multicohort strategy.

The impact of perioperative care on complications and short term outcome in ARM type rectovestibular fistula: An ARM-Net consortium study.

BACKGROUND: The impact of perioperative care interventions on postreconstructive complications and short-term colorectal outcome in patients with anorectal malformation (ARM) type rectovestibular fistula is unknown. METHODS: An ARM-Net consortium multicenter retrospective cohort study was performed including 165 patients with a rectovestibular fistula. Patient characteristics, perioperative care interventions, timing of reconstruction, postreconstructive complications and the colorectal outcome at one year of follow-up were registered. RESULTS: Overall complications were seen in 26.8% of the patients, of which 41% were regarded major. Differences in presence of enterostomy, timing of reconstruction, mechanical bowel preparation, antibiotic prophylaxis and postoperative feeding regimen had no impact on the occurrence of overall complications. However, mechanical bowel preparation, antibiotic prophylaxis ≥48 h and postoperative nil by mouth showed a significant reduction in major complications. The lowest rate of major complications was found in the group having these three interventions combined (5.9%). Multivariate analyses did not show independent significant results of any of the perioperative care interventions owing to center-specific combinations. At one year follow-up, half of the patients experienced constipation and this was significantly higher among those with preoperative mechanical bowel preparation. CONCLUSIONS: Differences in perioperative care interventions do not seem to impact the incidence of overall complications in a large cohort of European rectovestibular fistula-patients. Mechanical bowel preparation, antibiotic prophylaxis ≥48 h, and postoperative nil by mouth showed the least major complications. Independency could not be established owing to center-specific combinations of interventions. TYPE OF STUDY: Treatment study. LEVEL OF EVIDENCE: III.

Prevalencia del Estrés Postraumático en médicos residentes, expuestos al SARS-COV-2 / Prevalence of posttraumatic stress in resident doctors, exposed to SARS-COV-2

Objetivo: Determinar la prevalencia del trastorno de estrés postraumático (TEPT) en una muestra de médicos residentes del Hospital de Clínicas, José de San Martín, Buenos Aires, Argentina, un año después del cierre total durante la cuarentena por COVID-19. Materiales y métodos: Se administraron los siguientes cuestionarios autoadministrados: una encuesta demográfica, el cuestionario de la Escala de Trauma de Davidson y la Escala de Experiencias Disociativas (EED). Se excluyeron a los residentes de primer año de especialidades básicas, a aquellos que por su especialidad no tienen contacto con pacientes y a los médicos con licencia fueron excluidos. Resultados: La prevalencia de TEPT fue de 24.3% (n=25). Las medianas de las puntuaciones de DES fueron mayores en los participantes con puntaje positivo para TEPT en comparación con los que no lo presentaban (Mann-Whitney U:13.30, p = 0.001). Se encontraron asociaciones entre el género (X2:6.074, p = 0.013), el TEPT y el tipo de especialidad (prueba exacta de Fisher, p = 0.017). No se encontraron otras asociaciones entre las demás variables analizadas y el TEPT. Conclusion: La prevalencia del TEPT fue similar a los informes previos. Se hallaron asociaciones entre este desorden, el género y el tipo de especialidad. Estos resultados deberían llamar la atención de los sistemas de salud para establecer medidas preventivas y terapéuticas para manejar esta situación.

Objective: Determine the prevalence of posttraumatic stress disorder (PTSD) in a sample of resident doctors of the Hospital de Clínicas, José de San Martín, Buenos Aires, Argentina, one year after the total closure during the quarantine by COVID-19. Materials and Methods: The following self-administered questionnaires were dispensed: a demographic survey, the Davidson Trauma Scale questionnaire, and the Scale of Dissociative Experiences (EED). First year residents of basic specialties were excluded, those who for their specialty do not have contact with patients and licensed doctors were excluded. Results: PTSD prevalence was 24.3% (n = 25). The medium-sized ones were greater in the participants with positive score for PTSD compared to those who did not present it (Mann-Whitney U: 13.30, p = 0.001). Associations between the genre were found (X2: 6,074, p = 0.013), the PTSD and the type of specialty (Fisher's exact test, p = 0.017). No other associations were found between the other variables analyzed and the PTSD. Conclusion: The prevalence of the PTSD was similar to the previous reports. Associations between this disorder, gender and type of specialty were found. These results should draw the attention of health systems to establish preventive and therapeutic measures to handle this situation

Selective upregulation of cardiac endothelin system in patients with ischemic but not idiopathic dilated cardiomyopathy: endothelin-1 system in the human failing heart.

Only scarce information is available on the activity and modifications of the cardiac endothelin (ET)-1 system in heart failure due to ischemic (ICM) or idiopathic dilated (DCM) cardiomyopathy. The activity of the ET-1 system was investigated by measuring cardiac ET-1 and big ET-1 formation and quantifying cardiac mRNA for prepro-ET-1 (ppET-1), ET-converting enzyme-1, and ET(A) and ET(B) receptors both in myocardium and in isolated myocytes using Northern blot, reverse transcription-polymerase chain reaction, and in situ hybridization in 22 patients with DCM and 20 with ICM who underwent cardiac transplantation and in 7 potential heart transplant donors (nonfailing hearts). Notwithstanding a similar increase of plasma ET-1 in the 2 groups, cardiac ET formation, mRNA levels for ppET-1, and ET(A) and ET(B) receptors were higher on both the myocardium and isolated myocytes from ICM than on those from DCM hearts (P<0.001 for all). ppET-1 and ET-converting enzyme-1 mRNAs were expressed on myocytes and endothelial and interstitial cells in ICM, whereas in DCM and nonfailing hearts they were mainly expressed on nonmyocyte cells. In both ICM and DCM, the ET(A) mRNA signal was expressed on both myocytes and nonmyocyte cells, whereas ET(B) mRNA was almost exclusively localized on nonmyocyte cells. ET(A)- and ET(B)-specific receptor binding was increased on both myocytes and cardiac membranes, showing a positive correlation with left ventricular ejection fraction in ICM (r=0.78 and 0.70) but not in DCM patients. The present results show that human ventricular myocytes express all of the components of the ET-1 system, which is selectively upregulated in ICM patients and appears to be functionally important in the maintenance of cardiac function.

Longitudinal Strain Stress-Echo Evaluation of Aged Marginal Donor Hearts: Feasibility in the Adonhers Project.

BACKGROUND: The Adonhers (aged donor heart rescue by stress-echo protocol) Project was created to resolve the current shortage of donor hearts. One of the great limits of stress echo is the operator dependency. Speckle-tracking echocardiography (STE), offering a quantitative objective analysis of myocardial deformation, may help to overcome this limit. This study aimed to verify feasibility of a stress-strain echo analysis in selection of aged donor hearts for heart transplant. METHODS: From February 2014 to October 2015, 22 marginal candidate donors (16 men) ages 58 ± 4 years were initially enrolled. After legal declaration of brain death, all marginal donors underwent bedside echocardiography, with baseline and (when resting echocardiography was normal) dipyridamole (0.84 mg/kg in 6 minutes) stress echo. In all patients, left ventricular (LV) longitudinal myocardial deformation was obtained by STE in the 4-, 2-, and 3-chamber views, obtaining the average global longitudinal strain (GLS). GLS was assessed at baseline and at the peak of stress echo. RESULTS: Baseline echocardiography showed wall motion abnormalities in 9 patients (excluded from donation). Stress echocardiography was performed in the remaining 13 patients. Results were normal in 8, who were uneventfully transplanted in marginal recipients. Stress results were abnormal in 5 (excluded from donation). STE was obtained in all cases (100% feasibility) and ΔGLS was significantly different between normal and pathological stress-echo (+13.2 ± 5.2 versus -6.1% ± 3.1%, P = .0001, respectively). CONCLUSIONS: STE showed an excellent feasibility in analysis of LV myocardial longitudinal strain at baseline and at the peak of stress echo of marginal heart donors. Further experience is needed to confirm STE as a valuable additional mean to better interpret stress echo in marginal donors.

Activation of cardiac renin-angiotensin system in unstable angina.

OBJECTIVES: The aim of this study was to investigate the activity of the cardiac renin-angiotensin system (RAS) in unstable angina (UA). BACKGROUND: Angiotensin (Ang) II locally produced by continuously operating cardiac RAS may affect the pathophysiology of UA. METHODS: In 35 patients with UA, 32 with stable effort angina (SA) and 21 with atypical chest pain (controls), cardiac RAS was investigated during coronary angiography after five days of Holter monitoring by combining the measurement of aorta-coronary sinus gradient for Ang I and Ang II with the kinetics study of 125I-Ang I. Messenger RNAs (mRNA) for all the components of RAS were also quantified with the reverse transcriptase-polymerase chain reaction (RT-PCR) and localized by in situ hybridization in myocardial biopsy specimens from patients who underwent aorta-coronary bypass surgery. RESULTS: Cardiac Ang II generation was higher in patients with UA than it was in patients with SA or in controls (p < 0.001) due to increased de novo cardiac Ang I formation and its enhanced fractional conversion rate to Ang II. Messenger RNA levels for angiotensinogen (AGTN), angiotensin-converting enzyme (ACE) and Ang II type 1 (AT1) subtype receptors were higher in patients with UA (p < 0.01) than they were in patients with SA or in control hearts. Messenger RNAs for AGTN and ACE were almost exclusively expressed on endothelial and interstitial cells. Angiotensin II formation was correlated with ischemia burden (p < 0.001). However, the amount of Ang II formed and the expression levels of mRNAs for AGTN, ACE and AT1 were not related to the time that had elapsed since the last anginal attack. CONCLUSIONS: In patients with UA, cardiac RAS is activated, resulting in increased Ang II formation. Myocardial ischemia is essential for RAS activation, but it is unlikely to be a direct and immediate cause of RAS activation.

C2 and C0 values for monitoring cyclosporine therapy in stable heart transplant recipients.

INTRODUCTION: We sought to evaluate the behavior of C2 values and their correlation with acute rejection episodes and cyclosporine (CyA) side effects in heart transplant patients whose immunosuppressive therapy, was monitored with C0 trough levels. METHODS: Sixty stable patients who had received heart transplants from 3 months to 60 months prior were randomly observed from September 2001 to June 2004. Four area under the concentration-time curves (AUC) were performed on each patient, a total of 240 AUC curves. RESULTS: Regarding the variability of CyA absorption, two groups of patients were distinguished: group A, "constant absorbers," namely, low variability (<15%) of CyA absorption; group B, "inconstant absorbers" patients with higher (>15%) variability of absorption. Group B patients showed more acute rejection episodes (41%) than group A (19%). CyA side effects were more serious in patients with higher variability of absorption: systemic hypertension, neurological disorders, hyperlipidemia, and gum hyperplasia; Group B patients who developed CyA side effects showed higher maximum and mean C2 levels (P < .05) than group A patients. No differences were found with regard to renal dysfunction between the two groups: all patients showed a mean increase of serum creatinine by at least 50% compared to the baseline value. CONCLUSION: Higher C2 levels were not sufficient to predict acute rejection compared to lower but constants, C2 levels. Patients with inconstant absorption were more often overexposed to CyA than underexposed, developing more side effects than patients with lower variability of absorption. Monitoring CyA therapy with C0 and C2 may prevent over- or underexposure to the drug.

Bilateral Ureteral Obstruction in Children after Appendectomy.

Acute renal failure due to bilateral ureteral obstruction is a rare complication after appendectomy in children. We report a case of bilateral ureteric obstruction in a 14-year-old boy nine days after surgery for an acute appendicitis. After saline-filling of the urinary bladder, transabdominal ultrasound demonstrated bilateral hydronephrosis of moderate degree. No abscess was found with CT but presence of millimetric stones on both distal ureters was shown, with bilateral calyceal dilatation. Cystoscopy revealed inflammatory changes in the bladder base. Following introduction of bilateral ureteric stents, there was rapid normalisation of urinary output and serum creatinine.
