Fabrizio Romano, Mattia Garancini, Arianna Libera Ciravegna, Fabio Uggeri, Luca Degrate, Matteo Maternini, Franco UggeriDepartment of General Surgery (Chirurgia I), San Gerardo Hospital, University of Milan-Bicocca, Monza, ItalyAbstract: Splenectomy has been performed for a heterogeneous group of hematologic diseases with a therapeutic or diagnostic purpose or as part of the staging process in Hodgkin's disease. Most patients undergoing therapeutic splenectomy are chronically ill with significant splenomegaly. This scenario can be associated with a high risk of postoperative morbidity and mortality due to the prolonged course of disease for patients with myelofibrosis; their susceptibility to infection, thrombosis, and hemorrhage; and the severe enlargement of their spleens. We have reviewed the main papers published about postoperative complications after splenectomy, analyzing the risk factors, prevention measures, and respective treatments. Great care must be taken in the management of patients presenting malignant diseases, splenomegaly, and hemostasis disorder. Moreover, despite the faster discharge that new surgical techniques now allow, close attention should be paid to symptoms reported by patients, in order to avoid potentially life-threatening complications such as portal vein thrombosis, pancreas injuries, and overwhelming postsplenectomy infection.Keywords: hematologic disease, complications, postoperative, laparoscopi

Extensive Sclerosing Mesenteritis of the Rectosigmoid Colon Associated with Erosive Colitis

Sclerosing mesenteritis is a rare, idiopatic, usually benign, inflammatory process of the mesenteric adipose tissue. The most common site of involvement is the small bowel mesentery. We present a case of sclerosing mesenteritis of the rectosigmoid colon as a cause of severe abdominal pain, abdominal obstruction, and ischemic colic mucosal lesions. Contrast enema, colonoscopy, angiography, and CT were the imaging modalities used. A 20 cm diameter, fibrotic mass causing extensive compression of rectosigmoid colon was found at laparotomy. Histological examination showed extended fibrosis, inflammatory cells infiltration, lipophages, and granulomas within the mesenteric adipose tissue associated with erosive colitis. Clinical presentation and treatment are discussed

Global overview of the management of acute cholecystitis during the COVID-19 pandemic (CHOLECOVID study)

Background: This study provides a global overview of the management of patients with acute cholecystitis during the initial phase of the COVID-19 pandemic. Methods: CHOLECOVID is an international, multicentre, observational comparative study of patients admitted to hospital with acute cholecystitis during the COVID-19 pandemic. Data on management were collected for a 2-month study interval coincident with the WHO declaration of the SARS-CoV-2 pandemic and compared with an equivalent pre-pandemic time interval. Mediation analysis examined the influence of SARS-COV-2 infection on 30-day mortality. Results: This study collected data on 9783 patients with acute cholecystitis admitted to 247 hospitals across the world. The pandemic was associated with reduced availability of surgical workforce and operating facilities globally, a significant shift to worse severity of disease, and increased use of conservative management. There was a reduction (both absolute and proportionate) in the number of patients undergoing cholecystectomy from 3095 patients (56.2 per cent) pre-pandemic to 1998 patients (46.2 per cent) during the pandemic but there was no difference in 30-day all-cause mortality after cholecystectomy comparing the pre-pandemic interval with the pandemic (13 patients (0.4 per cent) pre-pandemic to 13 patients (0.6 per cent) pandemic; P = 0.355). In mediation analysis, an admission with acute cholecystitis during the pandemic was associated with a non-significant increased risk of death (OR 1.29, 95 per cent c.i. 0.93 to 1.79, P = 0.121). Conclusion: CHOLECOVID provides a unique overview of the treatment of patients with cholecystitis across the globe during the first months of the SARS-CoV-2 pandemic. The study highlights the need for system resilience in retention of elective surgical activity. Cholecystectomy was associated with a low risk of mortality and deferral of treatment results in an increase in avoidable morbidity that represents the non-COVID cost of this pandemic

Interpreting neonatal hip sonography: intraobserver and interobserver variability.

OBJECTIVES: The purpose of this study is to state the reliability of neonatal hip ultrasound interpretation, defining the intra and interoperator variability in the evaluation of the scans. METHODS: We considered a sample of 2071 scans (coming from 798 patients who attended the screening programme for hip dysplasia), which were interpreted by the operator who obtained and read the images at the screening time and then by a different operator who saw the images for the first time. RESULTS: Both the intra and interoperator variability of α and β angles' values resulted statistically not significative (intraclass correlation coefficient > 0.8) and determining a class shift (according to the Graf's classification) in a nonstatistically significative number of cases (agreement percentage >91% and Cohen's κ >0.8). CONCLUSION: Hip sonography can reliably detect hip dysplasia and the intra and interoperator variability in the interpretation of the exam is NS when the examination is correctly executed

Cognitive stimulation in cognitively impaired individuals and cognitively healthy individuals with a family history of dementia: short-term results from the “Allena-Mente” randomized controlled trial.

Objective We evaluated the short-term efficacy of a protocol of cognitive stimulation (CS), compared with a sham intervention, on cognitive performance in cognitively healthy individuals with a family history of dementia (NDFAM) and in non-demented individuals with cognitive impairment (CI). Methods We performed a randomized controlled trial of CS in NDFAM and CI. CS consisted in 10 twice weekly meetings of CS focused on a specific cognitive area. CS was compared with a sham intervention (CT) using Mini-mental state examination (MMSE), Montreal Cognitive Assessment (MoCA), and the Corsi test. All study participants were typed for the presence of apolipoprotein E (APOE)-Ɛ4. Results Cognitively healthy NDFAM showed a higher net cognitive gain after CS, as reflected in their MoCA score, and a borderline significant net increase in visuospatial memory (Corsi test) compared with those receiving the CT. APOE-Ɛ4 carriers showed a less significant improvement on the Corsi test with respect to APOE-Ɛ4 non-carriers. In the CI sample, the MoCA and Corsi test results did not differ between the cognitively stimulated subjects and the controls. No changes in MMSE scores were found in either sample of subjects. Conclusions These findings suggest that CS as structured in this study is an effective treatment in cognitively healthy individuals, whereas it is less effective in individuals with CI. Moreover, evaluation of APOE-Ɛ4 status provided evidence of a substantial genetic contribution to the efficacy of CS on visuospatial memory as measured using the Corsi test
