RESUMEN
Abstract: Neurofibromatosis type 1 (NF1), is a rare genetic disorder that may involve almost every organ system in the body such as cutaneous, ophthalmologic and central and peripheral nervous system. Cutaneous findings are usually the first sign of the disease. In this study, we investigate the real prevalence of xanthogranulomas juvenile (JXG) and possible correlation with lymphoproliferative diseases. This is a retrospective study conducted on a population with NF1 followed by February 1983 to February 2022 at the "Sapienza" University of Rome, Italy. We investigate the real prevalence of juvenile xanthogranuloma in NF1 and possible correlation with lymphoproliferative diseases. JXG was present in 39 cases (3.1%). JXG is more frequent in NF1 than in the general population while the possible association with lymphoproliferative diseases in NF1 remains controversial.

Objective: To investigate the risk and pattern of tumors in italian neurofibromatosis type 1 (NF1) patients. Materials and Methods: A retrospective single institution case review of 711 patients (seen between March 1992 and February 2018) with NF1 was conducted to identify individuals with diagnoses of both NF1 and neoplasm. NF1-associated tumors have been collected and analyzed. Results: We identified 221 tumors in 191 subjects with a percentage of 26.9%, diagnosed at a median age of 32.5 years (range, 0.6-70.1 years); 111 of these patients were females (58%) and all were fol-lowed up for a median of 5.3 years. The cumulative risks for tumor in patients with NF1 by the ages of 30 and 60 years were 10% and 42.5%, respectively. In our patients with tumor, overall survival at 70 years was significantly shorter than in those without it (50% vs 95%, P<0.0001). We found an unequivocally increased incidence for breast cancer in females (33 cases observed). Conclusions: Tumors that develop in patients with NF1 are heterogeneous, our data are consistent with other reports suggesting an increase in some cancers risk among these individuals, therefore systematic medical follow-up in people with NF1 is important.

Pyemotes ventricosus is a free-living mite feeding on larvae or nymphs of insects, including moths, beetles, wasps and bees, that are usually found in grain, straw and firewood. When present in great number or when its food is lacking, it could accidentally bite mammals, including humans, causing a highly pruritic self-limiting dermatitis, sometimes followed by a lymphangitis known as "comet sign".We present a singular case of mite lymphangitis that surrounds and delimitates breast prosthesis in a 30-year-old Caucasian woman. Other bite in the lower abdomen did not present comet sign. The patient got the infestation in her vacation home in the South of Italy, uninhabited for 10 months since COVID-19 confinement. We hypothesize that the previous surgery made the lymphatic vessels more prone to inflammation and we compare other insect bites that can occur vacationing in a long period uninhabited room.A delayed diagnosis of comet sign implies a retarded fumigation allowing new mite bites and, in this case, extends the patient's preoccupation about the prosthesis rejection.

ABSTRACT: Madelung's disease is a rare syndrome characterized by the pre-sence of multiple masses of unencapsulated adipose tissue, symme-trically distributed throughout different regions. It predominantly affects middle-aged men of Mediterranean origin with a history of alcoholism. The pathogenesis is still unknown. Diagnosis is essentially established through clinical history and physical examination. We report two cases for their unusual presentation and to emphasize the importance of early diagnosis.

PURPOSE: This study aims to identify in patients with neuroendocrine neoplasia (NEN) the potential correlation between FDG-PET findings and responses to everolimus therapy to identify predictors of long-term efficacy. METHODS: Retrospective analysis of patients with sporadic, advanced, progressive NEN treated with everolimus was performed based on the available data on FDG-PET patients obtained before commencing therapy. Data are expressed as the median (25-75th IQR). Risk factor analysis and survival analysis were performed by logistic regression and Cox proportional hazard regression and the determination of Kaplan-Meier curves, as appropriate. RESULTS: Sixty-six patients were evaluated (NET G1 19.7%, NET G2 75.7%, and NET G3 4.6%), including 45.4% with positive FDG-PET findings. Overall, disease stabilization and a partial response were achieved for 71.2% and 6% of patients, respectively. A long-term response (> 24 months) was observed in 33% of patients. Ki67 was the only predictor of tumor progression (p = 0.03). No significant difference in clinical outcomes was observed between patients with positive or negative FDG-PET findings (median PFS was 24 months and 18 months, respectively, p = 0.337; the disease control rate was 83.3% and 70%, respectively, p = 0.245). CONCLUSIONS: Everolimus is a valid therapeutic option for advanced, progressive, well-differentiated NEN, even in patients with positive FDG-PET findings.

Perforated diverticulitis is an emergent clinical condition and its management is challenging and still debated. The aim of this position paper was to critically review the available evidence on the management of perforated diverticulitis and generalized peritonitis in order to provide evidence-based suggestions for a management strategy. Four Italian scientific societies (SICCR, SICUT, SIRM, AIGO), selected experts who identified 5 clinically relevant topics in the management of perforated diverticulitis with generalized peritonitis that would benefit from a multidisciplinary review. The following 5 issues were tackled: 1) Criteria to decide between conservative and surgical treatment in case of perforated diverticulitis with peritonitis; 2) Criteria or scoring system to choose the most appropriate surgical option when diffuse peritonitis is confirmed 3); The appropriate surgical procedure in hemodynamically stable or stabilized patients with diffuse peritonitis; 4) The appropriate surgical procedure for patients with generalized peritonitis and septic shock and 5) Optimal medical therapy in patients with generalized peritonitis from diverticular perforation before and after surgery. In perforated diverticulitis surgery is indicated in case of diffuse peritonitis or failure of conservative management and the decision to operate is not based on the presence of extraluminal air. If diffuse peritonitis is confirmed the choice of surgical technique is based on intraoperative findings and the presence or risk of severe septic shock. Further prognostic factors to consider are physiological derangement, age, comorbidities, and immune status. In hemodynamically stable patients, emergency laparoscopy has benefits over open surgery. Options include resection and anastomosis, Hartmann's procedure or laparoscopic lavage. In generalized peritonitis with septic shock, an open surgical approach is preferred. Non-restorative resection and/or damage control surgery appear to be the only viable options, depending on the severity of hemodynamic instability. Multidisciplinary medical management should be applied with the main aims of controlling infection, relieving postoperative pain and preventing and/or treating postoperative ileus. In conclusion, the complexity and diversity of patients with diverticular perforation and diffuse peritonitis requires a personalized strategy, involving a thorough classification of physiological derangement, staging of intra-abdominal infection and choice of the most appropriate surgical procedure.

OBJECTIVE: To better understand the real prevalence of cutaneous manifestations, in Neurofibromatosis type 1. MATERIALS AND METHODS: We reviewed all clinical charts of 1102 NF1 patients followed by February 1983 to February 2020 at the "Sapienza" University of Rome, Italy. NF1 patients are seen usually every year by a dermatologist. RESULT: Café-au-lait macules were shown in 1063 patients (96.5%), axillary and inguinal freckling in 991 (90%) and neurofibromas in 861 (78.1%). Other skin manifestations included: lipoma (6.2%), nevus anemicus (3.9%), psoriasis (3.4%), spilus nevus (3.2%), juvenile xanthogranuloma (3.2%), vitiligo (2.3%), Becker's nevus (1.9%), melanoma (0.7%) and poliosis (0.5%). CONCLUSION: Neurofibromatosis type 1 is a multisystem disorder primarily involving the skin and nervous system. The clinical manifestations are extremely variable even within a family. This study was performed to delineate the prevalence of cutaneous manifestations in NF1.

PURPOSE: To develop and validate an Artificial Intelligence (AI) model based on texture analysis of high-resolution T2 weighted MR images able 1) to predict pathologic Complete Response (CR) and 2) to identify non-responders (NR) among patients with locally-advanced rectal cancer (LARC) after receiving neoadjuvant chemoradiotherapy (CRT). METHOD: Fifty-five consecutive patients with LARC were retrospectively enrolled in this study. Patients underwent 3 T Magnetic Resonance Imaging (MRI) acquiring T2-weighted images before, during and after CRT. All patients underwent complete surgical resection and histopathology was the gold standard. Textural features were automatically extracted using an open-source software. A sub-set of statistically significant textural features was selected and two AI models were built by training a Random Forest (RF) classifier on 28 patients (training cohort). Model performances were estimated on 27 patients (validation cohort) using a ROC curve and a decision curve analysis. RESULTS: Sixteen of 55 patients achieved CR. The AI model for CR classification showed good discrimination power with mean area under the receiver operating curve (AUC) of 0.86 (95% CI: 0.70, 0.94) in the validation cohort. The discriminatory power for the NR classification showed a mean AUC of 0.83 (95% CI: 0.71,0.92). Decision curve analysis confirmed higher net patient benefit when using AI models compared to standard-of-care. CONCLUSIONS: AI models based on textural features of MR images of patients with LARC may help to identify patients who will show CR at the end of treatment and those who will not respond to therapy (NR) at an early stage of the treatment.

OBJECTIVE: The objective of this study was to identify possible biopsychosocial predictors of organizational complexity in patients referred to the consultant psychiatrist for assessment before liver transplantation. METHODS: This was a case-control study. All psychiatric consultations performed before and after liver transplantation from January 1, 2008 to December 31, 2013 were included. Complexity was operationalized as "undergoing two or more psychiatric consultations". Controls were defined as patients who were assessed only once by the consultant. Cases were represented by patients who underwent two or more consultations. Statistical analysis was performed with STATA 13.1, using logistic regressions. RESULTS: In this study, 515 consultations were requested for 309 patients potentially eligible for liver transplantation. Controls were 209 (67.6%); cases were 100 (32.4%). Positive psychiatric history (odds ratio [OR] = 2.44; 95% confidence interval [CI], 1.43-4.16), viral or toxic (alcohol- or drug-related) liver disease (OR = 1.93; 95% CI, 1.09-3.42), use of psychotropic medications at the baseline (OR = 2.15; 95% CI, 1.14-4.07), and female gender (OR = 1.77; 95% CI, 1.01-3.11) were significantly associated with an increased probability of being cases. CONCLUSIONS: Positive psychiatric history, viral or toxic liver disease, use of psychotropic medications at the index referral, and female gender are possible biopsychosocial predictors of complexity in patients eligible for liver transplantation.

PURPOSE: To analyze diffusion-weighted magnetic resonance imaging (DW-MRI) for treatment response assessment in locally advanced rectal cancer (LARC). PATIENTS AND METHODS: Patients with histologically proven rectal adenocarcinoma, stage II-III disease, were enrolled and underwent surgery following neoadjuvant chemoradiotherapy (nCRT). All patients were referred for a DW-MRI protocol on a 3 Tesla MR-system, consisting of axial T2-weighted and DWI sequences prior (I), during (II) and after (III) nCRT. Corresponding apparent diffusion coefficient (ADC) values were calculated. RESULTS: Between February 2011 and June 2015, 37 patients participated in the study. All patients completed programmed treatment. Overall, 11 patients (29.7%) had pathologic complete response (pCR). No correlation between the mean pre- (ADC-I), during (ADC-II), post- (ADC-III) ADC and the reduction in tumor size after nCRT was recorded. No substantial difference in the ADC distribution was found between pCR and no-pCR patients. The ADC-II level significantly increased in the pCR cases (T = 1.675; p < 0.05). CONCLUSION: ADC value could be useful for discriminating between the pCR patients and the no-pCR patients. Further studies are necessary to identify the optimal MRI parameters combination to predict tumor response to nCRT. It is hoped that these data will provide the basis for a more solid scientific evidence.

AIM: To investigate the correlation between conventional computed tomography (CT) features, quantitative texture analysis (QTA), epidermal growth factor receptor (EGFR) mutations, and survival rates in patients with lung adenocarcinoma. MATERIALS AND METHODS: Sixty-eight patients were evaluated for conventional CT features and QTA in this retrospective study. A multiple logistic regression analysis and receiver operating characteristics (ROC) curve analysis versus death and EGFR status was performed for CT features and QTA in order to assess correlation between CT features, QTA, EGFR mutations, and survival rates. A p-value <0.05 was regarded to indicate a statistically significant association. RESULTS: An EGFR mutation was identified in 26/68 tumours (38.2%). A negative association was found between EGFR mutation and emphysema (p < 0.0001) whereas a positive correlation was found with necrosis (p=0.017), air bronchogram (p=0.0304), and locoregional infiltration (p=0.0018). Mean, standard deviation, and skewness were found to have significant correlation with EGFR mutation (p=0.0001; p=0.0001; p=0.0459; Fig 3). The only parameter correlated with the event death was entropy (r=0.2708; p=0.0329). CONCLUSION: Both qualitative and quantitative analysis disclosed potential associations between CT features and QTA parameters, EGFR mutations and prognosis; these correlations need to be confirmed in larger studies to be used as imaging biomarkers in the management of patients affected by lung adenocarcinoma.

OBJECTIVES: To develop guidelines describing a standardised approach to patient preparation and acquisition protocols for magnetic resonance imaging (MRI), computed tomography (CT) and ultrasound (US) of the small bowel and colon, with an emphasis on imaging inflammatory bowel disease. METHODS: An expert consensus committee of 13 members from the European Society of Gastrointestinal and Abdominal Radiology (ESGAR) and European Society of Paediatric Radiology (ESPR) undertook a six-stage modified Delphi process, including a detailed literature review, to create a series of consensus statements concerning patient preparation, imaging hardware and image acquisition protocols. RESULTS: One hundred and fifty-seven statements were scored for agreement by the panel of which 129 statements (82 %) achieved immediate consensus with a further 19 (12 %) achieving consensus after appropriate modification. Nine (6 %) statements were rejected as consensus could not be reached. CONCLUSIONS: These expert consensus recommendations can be used to help guide cross-sectional radiological practice for imaging the small bowel and colon. KEY POINTS: ⢠Cross-sectional imaging is increasingly used to evaluate the bowel ⢠Image quality is paramount to achieving high diagnostic accuracy ⢠Guidelines concerning patient preparation and image acquisition protocols are provided.

OBJECTIVE: The aim of this study was to evaluate the clinical usefulness of computed tomography colonography (CTC) in the preoperative staging in patients with abdominal pain for occlusive colorectal cancer (CRC) and to compare the results of CTC with the surgical ones. PATIENTS AND METHODS: 127 patients with abdominal pain, iron deficiency anemia and occlusive CRC underwent a CTC examination in prone position without intravenous contrast agent and in prone position after administration of intravenous contrast medium. All the patients underwent surgery after CTC. Two radiologists with different experience analyzed the images first independently and then by consensus. They evaluated the location of the lesion, the depth of the invasion of the colon-rectal wall (T stage), lymph node involvement (N stage) and the presence or absence of distant metastasis (M stage). CTC findings were correlated with surgical outcomes. RESULTS: The overall accuracy values for tumour localization according to consensus reading of CTC examinations in comparison to surgical results were 100% (K = 1, p = 0.0001). The overall accuracy values of agreement for T staging of reader 1, reader 2 and consensus reading of CTC examinations in comparison to surgical results were respectively 95.5% (K = 0.876, p = 0.0035), 93.3% (K = 0.858, p = 0.0037) and 97.7% (K = 0.926, p = 0.0014) for ≤ T2; 91.3% (K = 0.839, p = 0.0027), 88.3% (K = 0.817, p = 0.0031), and 92.9% (K = 0.894, p = 0.0025) for T3; 89.6% (K = 0.825, p = 0.0037), 86.2% (K = 0.837, p = 0.0032) and 89.6% (K = 0.821, p = 0.0023) for T4. The overall accuracy values for N staging for reader 1, reader 2 and consensus reading was 90.2% (K = 0.865, p = 0.0029). The overall accuracy values for M staging of reader 1, reader 2 and consensus reading was 92% (K = 0.875, p = 0.0019). CONCLUSIONS: CTC with is a very useful tool for accurate pre-treatment staging and localization of occlusive CRC.

AIM: To compare two regimens of reduced bowel preparation and faecal tagging for CT colonography. MATERIALS AND METHODS: Single centre, prospective, randomized, noninferiority study, in which 52 consecutive adults underwent routine CT colonography. Patients, following a three-day low-fibre diet, received one of the two reduced preparations: 1-L polyethylene glycol and four tablets of bisacodyl in association with 90 mL of Iopamidol for faecal tagging administered on the same day as CTC examination (group 1); or a standard "iodine-only" preparation, consisting in 180 ml of Iopamidol the day before the examination (group 2). Primary outcome was the overall quality of bowel preparation. RESULTS: Twenty-six patients per group were included. Per segment analysis showed preparation of diagnostic quality in 97.4% of segments in group 1 and in 95.5% in group 2 (p = ns). Per-patient analysis showed optimal quality of preparation in 76.9% of patients in group 1 and in 84.6% in group 2 (p = ns). Patient tolerability to both preparations was not different. CONCLUSION: A limited bowel preparation consisting of 1-L PEG and four tablets of bisacodyl in association with 90 mL of Iodine for faecal tagging administered on the same day as CTC examination is feasible and offers bowel cleansing comparable to "iodine-only" preparation. KEY POINTS: ⢠Low-dose PEG bisacodyl and Iopamidol preparation is feasible, providing adequate bowel cleansing. ⢠Faecal tagging is not different from the two limited preparations. ⢠Patient tolerability to the two colon cleansing regimens is similar.

This is an official guideline of the European Society of Gastrointestinal Endoscopy (ESGE) and the European Society of Gastrointestinal and Abdominal Radiology (ESGAR). It addresses the clinical indications for the use of computed tomographic colonography (CTC). A targeted literature search was performed to evaluate the evidence supporting the use of CTC. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system was adopted to define the strength of recommendations and the quality of evidence. Main recommendations 1 ESGE/ESGAR recommend computed tomographic colonography (CTC) as the radiological examination of choice for the diagnosis of colorectal neoplasia. ESGE/ESGAR do not recommend barium enema in this setting (strong recommendation, high quality evidence). 2 ESGE/ESGAR recommend CTC, preferably the same or next day, if colonoscopy is incomplete. Delay of CTC should be considered following endoscopic resection. In the case of obstructing colorectal cancer, preoperative contrast-enhanced CTC may also allow location or staging of malignant lesions (strong recommendation, moderate quality evidence). 3 When endoscopy is contraindicated or not possible, ESGE/ESGAR recommend CTC as an acceptable and equally sensitive alternative for patients with symptoms suggestive of colorectal cancer (strong recommendation, high quality evidence). 4 ESGE/ESGAR recommend referral for endoscopic polypectomy in patients with at least one polyp â≥ â6â mm in diameter detected at CTC. CTC surveillance may be clinically considered if patients do not undergo polypectomy (strong recommendation, moderate quality evidence). 5 ESGE/ESGAR do not recommend CTC as a primary test for population screening or in individuals with a positive first-degree family history of colorectal cancer (CRC). However, it may be proposed as a CRC screening test on an individual basis providing the screenee is adequately informed about test characteristics, benefits, and risks (weak recommendation, moderate quality evidence).
