Abstract
There is a strong correlation between SARS-CoV-2 and the onset of autoimmune neurological disease with atypical clinical presentation, characterized by limited response to medical therapy, likely caused by the underlying mechanism of the virus itself. In situations like these, after the failure of pharmacological therapy, therapeutic apheresis, including immunoadsorption, can be pursued. Treatments with IMMUSORBA TR-350 columns have proven to be particularly effective in managing refractory forms of post-Covid-19 nephropathies, leading to complete recovery of disability and elimination of neurological signs and symptoms. We discuss the case of a patient with chronic inflammatory polyradiculopathy post-Covid-19, resistant to medical therapy, effectively treated with immunoadsorption.

Abstract
Aims and background The phenotypic expression of different APC mutations in familial adenomatous polyposis (FAP) is variable: two to three variants of the disease have been defined based on the severity of colonic manifestations. Age of onset and number of polypectomies per person-year of postsurgical follow-up were compared in two FAP families with very close mutation sites in the APC gene, in order to ascertain mutation-specific variation of expressivity. Families and APC mutations Family A (5 patients) carried a newly characterized mutation, a four bp deletion at codon 843. Family B (5 patients) carried a previously identified mutation at codon 835. Results Mean age of onset was 49.7 years in family A and 30.5 years in family B; number of polypectomies per person-year of follow-up was 1.05 for family A and 10.1 for family B (P <0.001). Conclusions There is significant variation of expressivity (allelic heterogeneity) in FAP between two mutations separated by only eight codons, located at the 5’ extremity of APC gene exon 15.

Abstract
PURPOSE Hypertension is considered an important cardiovascular (CV) risk for uremic patients on hemodialysis (HD). Its main pathogenetic factor is the extracellular fluid volume increase. METHODS This study aimed to evaluate the water distribution by electric bioimpedence (BIA) in hypertensive uremic patients treated with convective hemodialysis (HD) (group A) and with diffusive HD (group B). The patients were on antihypertensive therapy: angiotensin-converting enzyme (ACE)-inhibitors, beta blockers, calcium antagonists and angiotensin II (ATII) antagonists. RESULTS The BIA analysis demonstrated that the total and extracellular body water had the same distribution in the two groups with no statistical differences (Student's t-test); although the interdialytic weight gain was higher in group B than in group A. CONCLUSIONS Blood pressure (BP) was treated by less drug use in patients on convective HD than in patients on diffusive HD.

Abstract
Over the last few years emerging evidence indicate the involvement of herpes viruses in the pathogenesis of several medical complications in transplanted patients. Herpes viruses are transmitted via inter-human contact and cause a primary infection, which commonly fails to give clinical signs and may persist even for years in a latent state in healthy subjects. In transplanted patients, herpes viruses may be transmitted through the transplanted organ or may be reactivated because of the use of powerful immunosuppressive drugs. Moreover, the persistence of immunosuppression greatly favours the clinical expression and severity of virus infection. Thus, herpes viruses seem to be involved in both acute and chronic deterioration of graft function, in the pathogenesis of post-transplant lymphoproliferative disorders and Kaposi sarcoma, and even in vessel atherosclerosis. This review will focus on relevant clinical aspects of herpes-virus infection, namely cytomegalovirus, EBV, herpes simplex 1 and 2, varicella zoster virus, HHV-6, HHV-7 and HHV-8, in kidney transplanted patients.

Abstract
The aim of this study was to evaluate the accuracy of dynamic CT in the preoperative staging of gastric cancer. One hundred seven patients affected by gastric cancer diagnosed by endoscopic biopsy were prospectively staged by dynamic CT prior to tumor resection. After an oral intake of 400-600 ml of tap water and an intravenous infusion of a hypotonic agent, 200 ml of non-ionic contrast agent were administered by power injector using a biphasic technique. The CT findings were prospectively analyzed and correlated with the pathological findings at surgery. The accuracy of dynamic CT for tumor detection was 80 and 99% in early and advanced gastric cancer, respectively, with overall detection rate of 96% (103 of 107). Three early (pT1) and one advanced (pT2) cancers were undetected. Tumor stage as determined by dynamic CT agreed with pathological findings in 83 of 107 patients with an overall accuracy of 78%. The accuracy of CT in detecting increasing degrees of depth of tumor invasion when compared with pathological TNM staging was 20% (3 of 15) and 87% (80 of 92) in early and advanced cancer, respectively. The sensitivity, specificity, and accuracy of CT in the preoperative staging (pT3-pT4 vs pT1-pT2) was 93, 90, and 91.6%, respectively. The sensitivity, specificity, and accuracy of CT in assessing metastasis to regional lymph nodes was 97.2, 65.7, and 87%, respectively. Computed tomography correctly staged liver metastases in 105 of 107 patients with an overall sensitivity of 87.5% and specificity of 99 %. The sensitivity of peritoneal involvement was 30% when ascites or peritoneal nodules were absent. Our findings show that dynamic CTcan play a role in the preoperative definition of gastric cancer stage. The results can be used to optimize the therapeutic strategy for each individual patient prior to surgery, thus avoiding unnecessary intervention and allowing careful planning of extended surgery in eligible patients.

Abstract
Acquired cystic kidney disease (ACKD) is characterized by the substitution of renal parenchyma with multiple cysts in patients either with end stage renal disease who are treated for uremia with dialysis (as on haemodialysis--HD--as on peritoneal dialysis--PD) due to non cystic kidney diseases. The aim of our study was to value the prevalence of ACKD in our haemodialysed patients (with exclusion of polycystic disease and obstructive nephropathy), its relationship between clinical and bioumoral parameters, and its complications in the follow-up. We have studied 56 uremic patients (32f and 24m) on bicarbonate HD three in a week. All our patients underwent renal echography using ECO B mode ALOKA SSD500 with electronic convex sector probe 3.5 MHz for to diagnose ACKD. We divided the population of the study in two groups: the group A includes 23 patients with ACKD; the group B includes 33 patients without ACKD. We analyzed in all patients body mass index (BMI), protein catabolic rate normalized (nPCR), dialitic adequacy index (KT/V), Hb, the serum levels of EPO by ELISA test (MEDAL GmbH, GE, Diagnostika, Hamburg; normal values 5 divided by 30 mUI/ml). We have found a prevalence of 42% for ACKD and statistical significance between the two groups for the duration of HD and BMI (Anova p < 0.01). The EPO serum concentration was higher in the group A (p < 0.05), while their rhuEPO requirement was lower. In two patients of group with ACKD we have found renal carcinoma. In conclusion, by our experience should be opportune to carry out a renal echography at the start of dialysis treatment and every six months for patients with ACKD and every year for those without ACKD. It is necessary to perform the echography of the kidney in all uremic patients before the start of haemo or peritoneal dialysis and report this examination in those patients with ACKD every six months and every year in those without ACKD.

Abstract
Systemic lupus erythematosus is a multisystem autoimmune disease characterized by the production of autoantibodies reacting with many different self antigens. The analysis of clinical expression and evolution of this disease is a milestone in the definition of therapeutic strategies. A parameter universally accepted as gold standard is lacking so far. About 60 indices for defining and measuring the activity of this disease have been proposed in the last 20 years. The most important of these are discussed in this review, focusing both on their role in the evaluation and outcome of patients and on the main studies assessing their validity and reliability.

Abstract
BACKGROUND Therapies of advanced melanoma patients with interleukin-2 (IL-2) and cytotoxic lymphocytes have produced interesting results, but a larger diffusion of these treatments is limited by the severe side effects due to IL-2 systemic infusion. A strictly regional administration of IL-2 and cells by an isolation perfusion (IP) in extracorporeal circulation (ECC) for the treatment of regional melanoma metastases could improve tolerability and efficacy of this specific modality of immunotherapy. METHODS Ten patients were submitted to adoptive immunotherapy with IL-2 and lymphokine-activated killer (LAK) cells by IP in ECC. The schedule of treatment included the first course of a 5-day systemic administration of IL-2 (Proleukin, EuroCetus 9-12 x 10(6) IU/m2/day continuous infusion); autologous LAK cells were obtained via leukapheresis and after in vitro activation were given (range 8-28 x 10(9)) along with IL-2 (120-2,400 IU/ml of perfusion priming) to the affected limb by IP; IL-2 (9-12 x 10(6) IU/m2/day) was also administered by systemic continuous infusion for 5 days starting on the day after IP. RESULTS All patients concluded the treatment without any major local or systemic toxicities. Clinical responses included one complete and six partial remissions; three patients had stable disease. All patients are alive. Follow-up after IP ranged from 12 to 35 months (median: 22). The analysis of circulating lymphocytes revealed the rapid disappearance of LAK cells, suggesting their extravasation and/or endothelial adhesion in perfused tissues. CONCLUSIONS IP with IL-2 and LAK cells is a new approach for the treatment of in-transit metastases due to cutaneous melanoma. The treatment appears to be feasible and reliable. Further biological and immunological studies should permit amelioration of the present modality of treatment.

Abstract
Ten patients who underwent surgery (5 right hepatectomy and 5 colectomy) for cancer participated in a clinical controlled study. They were treated with buprenorphine (i.v. slow infusion) to relieve postsurgical pain. We found an increased urinary excretion of this drug in patients who underwent hepatectomy as compared with patients who underwent colectomy. However no differences in the occurrence of side-effects and/or in the therapeutic effect were observed between the two groups. We conclude that buprenorphine can be effectively and safely used also in patients with a resection of liver parenchyma.

Abstract
In six kidney donors with normal baseline urinary albumin excretion (UAE) we studied the behavior of the UAE after 150 g of a meat protein meal and after a carbohydrate meal of equal caloric (1,370 kcal), water (1 liter) and sodium content (51 mEq). The mean creatinine clearance (Ccr) increased significantly after a protein load at the first (p less than 0.01) and second hour (p less than 0.05), while it did not change after the carbohydrate meal. The mean UAE increased significantly after the protein meal at the first (p less than 0.05) and second hour (p less than 0.05), while after the carbohydrate meal the mean values were increased at the first (p less than 0.05), second (p less than 0.05) and third hour (p less than 0.05). Furthermore, the mean values of UAE after the protein meal were significantly higher (p less than 0.05) than those found at the same time after the carbohydrate meal. Diuresis and natriuresis increased significantly after both meals. These findings show that the increased UAE after the protein meal may be due to a further increase in Ccr in the hyperfiltering remaining kidney, while the smaller increase in the UAE observed after the carbohydrate meal may be due to water load and increased urine flow, which impairs albumin tubular reabsorption. The prognostic importance of microalbuminuria after either meal is therefore uncertain.

Abstract
Twenty nine patients with pure dysgerminoma of the ovary were referred to the Institute of Radiology of the University of Florence between 1960 and 1983. Twenty six patients received radiation therapy after surgery; three cases, classified as Stage IA, were not submitted to postoperative radiation therapy. Five patients relapsed 2 to 16 months after initial surgery, and three of them died because of their tumours. Sites of relapse were found to be outside the treated volume in four out of these five patients. The overall survival rate for this series is 90%. The survival rate seems to depend not only on the stage of the disease, but also on initial accurate staging and appropriate therapy. Criteria for selecting patients from whom post-operative radiotherapy may be withheld are discussed.

Abstract
Multiple daily fractionation (MDF) was compared, in a cooperative study, with conventional fractionation (CF) in the radiation treatment of brain metastases. The 103 patients treated by MDF and the 44 given CF showed a similar response, in terms of neurologic improvement, survival, quality of residual life, and treatment-related morbidity. The hypothesis that MDF might give a better therapeutic ratio than CF was not confirmed in the present series. The short time period required gives MDF advantages in clinical practice.

Abstract
Sonography, contrast radiography, and endoscopy of the small and large intestine were performed in 32 patients, who had already undergone one or more intestinal resections for Crohn disease, with the aim of detecting possible relapses. Eleven patients proved to have had relapses; sonography revealed nine cases, with two false negatives and no false positives. Sensitivity proved to be 82%, specificity 100%, and overall accuracy 93.7%. Sonography enables the operator to distinguish between inflammatory and neoplastic lesions by means of structural study of the thickened bowel wall, paying particular attention to integrity of its layers.
