Abstract
BACKGROUND Incisional hernia (IH) is a common complication after abdominal surgery. Prevention of IH is matter of intense research. Prophylactic mesh reinforcement (PMR) has been shown to be promising in the minimization of IH risk after elective midline laparotomy. METHODS Systematic review and meta-analysis of randomized controlled trials (RCTs) comparing PMR vs. primary suture closure (PSC). Risk ratio (RR) and standardized mean difference (MD) were used as pooled effect size measures whereas 95% confidence intervals (95%CI) were used to assess relative inference. RESULTS Fourteen RCTs (2332 patients) were included. Overall, 1280 (54.9%) underwent PMR while 1052 (45.1%) PSC. Postoperative follow-up ranged from 12 to 67 months. The incidence of IH was reduced for PMR vs. PSC (13.4% vs. 27.5%). The estimated pooled IH RR for PMR vs. PSC is 0.38 (95% CI 0.24-0.58; p < 0.001). Stratified subgroup analysis according to mesh location shows a risk reduction for intraperitoneal (RR = 0.65; 95% CI 0.48-0.89), preperitoneal (RR = 0.18; 95% CI 0.04-0.81), retromuscular (RR = 0.47; 95% CI 0.24-0.92) and onlay (RR = 0.24; 95% CI 0.12-0.51) compared to PSC. The seroma RR was higher for PMR (RR = 2.05; p = 0.0008). No differences were found for hematoma (RR = 1.49; p = 0.34), surgical site infection (SSI) (RR = 1.17; p = 0.38), operative time (OT) (MD = 0.27; p = 0.413), and hospital length of stay (HLOS) (MD = -0.03; p = 0.237). CONCLUSIONS PMR seems effective in reducing the risk of IH after elective midline laparotomy compared to PSC in the medium-term follow-up. While the risk of postoperative seroma appears higher for PMR, hematoma, SSI, HLOS and OT seems comparable.

Abstract
BACKGROUND Hernia recurrence after laparoscopic repair is a perplexing problem. In an effort to reduce anatomical and clinical recurrences, different type of meshes have been used to bolster the esophageal hiatus. OBJECTIVE The aim of this study was to assess safety, medium-term efficacy, and quality of life improvement after laparoscopic repair of hiatal hernia reinforced with a biosynthetic absorbable mesh (Phasix-ST®). METHODS Observational single-center retrospective single-arm cohort study (November 2015-February 2021). We included all adult patients (> 18 years old) who underwent laparoscopic paraesophageal hernia repair with Phasix-ST® mesh and Toupet fundoplication. RESULTS Sixty-eight patients were included. The median postoperative stay was 3.2 days (range 2-9) and the postoperative complication rate was 11.7%. The median follow-up time was 27 months (range 1-53). No mesh-related complications were detected. Hernia recurrence was diagnosed in six patients (8.8%). The recurrence-free probability at 34 months was 0.89 (95% CI 0.807-0.988) while at 60 months was 0.86 (95% CI 0.76-0.97). Hernia recurrences were mostly observed between 21 and 36 months after the operation. None of the patients required surgical revision and all were managed with PPI. Postoperative dysphagia requiring endoscopic balloon dilatation occurred in 2.9% of patients. Compared to baseline, both the GERD-HRQL (15.2 ± 6.2 vs. 3.2 ± 3.1; p = 0.026) and all SF-36 items were significantly improved (p < 0.001). CONCLUSIONS Laparoscopic crura augmentation with Phasix-ST® mesh combined with a Toupet fundoplication is safe and seems effective in the medium-term follow-up. Phasix-ST® crural reinforcement resulted in low hernia recurrence rate with a sustained symptoms and quality of life improvement.

Abstract
PURPOSE Diastasis recti abdominis (DRA) or rectus diastasis is an acquired condition in which the rectus muscles are separated by an abnormal distance along their length, but with no fascia defect. To data there is no consensus about risk factors for DRA. The aim of this article is to critically review the literature about prevalence and risk factor of DRA. METHOD A total of 13 papers were identified. RESULTS The real prevalence of DRA is unknown because the prevalence rate varies with measurement method, measurement site and judgment criteria, but it is certainly an extremely frequent condition. Numbers of parity, BMI, diabetes are the most plausible risk factors. We identified a new anatomical variation in cadaveric dissection and in abdominal CT image evaluation: along the semilunar line the internal oblique aponeurosis could join the rectus sheath with only a posterior layer, so without a double layer (anterior and posterior) as usually described. We conducted a retrospective review of abdominal CT images and the presence of the posterior insertion only could be considered as a risk factor for DRA. CONCLUSION Further studies with large sample size, including nulliparous, primiparous, pluriparous and men too, are necessary for identify the real prevalence.

Abstract
BACKGROUND Hospitals performing surgery in Italy underwent important transformations in recent years, with decreasing economic resources and higher expected standards of care. Regional authorities acted differently across the country to adapt to the new scenario, generating heterogeneous outcomes. The Rizzoli Orthopedic Institute (ROI) in the Emilia-Romagna region started its reorganization in 2017, after the issue of new regional regulations about surgical activity. Aim of this paper is to describe the actions taken at ROI and discuss their outcomes. STUDY DESIGN Action-research. METHODS From 2017 to 2019 an action-research project was developed to introduce organizational changes within ROI and close the existing gaps between regional requirements and actual features of the Institute. Four areas of intervention were identified: surgical scheduling, appropriateness of surgical setting, monitoring and management of the surgical path and accountability. Progress was monitored through the collection of performance indicators and qualitative investigation of the organizational culture. RESULTS Changes were implemented in all areas of intervention. Key features were the introduction of Operating Room Management (ORM) skills and the establishment of multiprofessional teams to drive the changes. Performance indicators showed a positive trend in the comparison between 2017 and 2018. Improvements were observed in terms of productivity, scheduling, and respect of standard waiting time, while case-mix did not significantly change. CONCLUSIONS Effective ORM and collaborative practices can successfully drive the change towards a more efficient surgical process without increasing resources consumption.

Abstract
BACKGROUND Somatic mutations in coding regions of the genome may result in non-functional proteins that can lead to cancer or other diseases, however cancer mutations in the non-coding regions have rarely been studied and the interpretation of their effects is difficult. Non-coding mutations might act by breaking or creating transcription factor binding motifs in promoters, enhancers or silencers resulting in altered expression of target gene(s). A high number of mutations have been reported in coding and non-coding regions in cells of liver cancer. Hepatocyte nuclear factor 4α is a transcription factor that regulates the expression of several genes in liver cells, while the motifs it binds are frequently mutated in promoters and enhancers in liver cancer. AIM The aim of the study is to evaluate the genetic effects of a non-coding somatic mutation frequently observed in liver cancer. MATERIALS AND METHODS We evaluated experimentally the effects of a somatic mutation frequently reported in liver cancer as a motif-breaker for the binding of hepatocyte nuclear factor 4α. The effects of the mutation on protein binding and enhancer activity were studied in HepG2 cells via electrophoresis mobility shift assay and dual luciferase reporter assays. We also studied genome-wide promoter-enhancer interactions performing targeted chromosome conformation capture in liver tissue to identify putative target genes whose expression could be altered by the mutation. RESULTS We found that the mutation leads to reduced protein binding and a decrease in enhancer activity. The enhancer harboring the mutation interacts with the promoters of ANAPC13, MAP6D1 and MUC13, which have been implicated in liver cancer. CONCLUSIONS The study highlights the importance of non-coding somatic mutations, vastly understudied, but likely to contribute to cancer development and progression.

Abstract
Understanding the evolution of sediment connectivity associated with different land use and topographic changes is a prerequisite for a better understanding of sediment budgets and sediment transport processes. We used the Index of Sediment Connectivity (IC) developed by Cavalli et al. (2013) based on the original approach by Borselli et al. (2008) to study the effects of decadal-scale land use and topographic changes on sediment connectivity in mountain catchments. The input variables of the IC (i.e. land cover and topography) were derived from historical aerial photos using Structure from Motion-Multi View Stereo algorithms (SfM-MVS). The method was applied in different sub-catchments of the Upper River Cinca Catchment (Central Pyrenees), representative of three scenarios: (a) Land cover changes; (b) Topographic changes in agricultural fields (terracing); and (c) Topographic changes associated with infrastructure (road construction). In terms of land cover changes, results show that although connectivity is increased in some areas due to the establishment of new field crops, for most of the study area connectivity decreased due to afforestation caused by rural abandonment. Topographic changes due to the establishment of agricultural terraces affected connectivity to a larger degree than land cover changes. Terracing generally reduced connectivity due to the formation of flat areas in step-slopes, but in certain points, an increase in connectivity caused by the topographic convergence produced by terraces was observed. Finally, topographic changes associated with road construction greatly modified surface flow directions and the drainage network, resulting in changes in connectivity that may affect erosional processes nearby. The methodology used in this paper allows to study the effects of real decadal-scale land use and topographic changes on sediment connectivity and also evaluating and disentangling those changes. Furthermore, this approach can be a useful tool to identify potential risks associated with morphological and land use changes, involving road infrastructures.

Abstract
Large floods may produce remarkable channel changes, which determine damages and casualties in inhabited areas. However, our knowledge of such processes remains poor, as is our capability to predict them. This study analyses the geomorphic response of the Nure River (northern Italy) and nine tributaries to a high-magnitude flood that occurred in September 2015. The adopted multi-disciplinary approach encompassed: (i) hydrological and hydraulic analysis; (ii) analysis of sediment delivery to the stream network by means of landslides mapping; (iii) assessment of morphological modifications of the channels, including both channel width and bed elevation changes. The spatial distribution of rainfall showed that the largest rainfall amounts occur in the upper portions of the catchment, with cumulative rainfall reaching 300 mm in 12 h, and recurrence intervals exceeding 100-150 years. The unit peak discharge ranged between 5.2 and 25 m3 s-1 km-2. Channel widening was the most evident effect. In the tributaries, the ratio between post-flood and pre-flood channel width averaged 3.3, with a maximum approaching 20. Widening was associated with channel aggradation up to 1.5 m and removal of riparian vegetation. New islands formed due to the fragmentation of the former floodplain. In the Nure River, the average width ratio was 1.7, and here widening occurred mainly at the expenses of islands. Bed level dynamics in the Nure were varied, including aggradation, incision, and overall stability. The flood geomorphic effectiveness was more pronounced in the middle-higher portions of the basin. Planimetric and elevation changes were well correlated. Regression analysis of the relationship between widening and morphological/ hydraulic controlling factors indicated that unit stream power and confinement index were the most relevant variables. The study provides useful insights for river management, especially with regard to the proportion of the valley floor subject to erosion and/or deposition during large events.

Abstract
INTRODUCTION The high-throughput era remarkably changed molecular laboratory practice. Actually, the increasing number of processed samples requires to reduce the risk of operator biases, by automating or simplifying as much as possible both the analytical and the pre-analytical phases. Minimal residual disease (MRD) studies in hematology often require a simultaneous processing of many bone marrow and peripheral blood samples from patients enrolled in prospective, multicenter, clinical trials, monitored at several planned time points. METHODS In this study, we demonstrate that red blood cell lysis (RBL) pre-analytical procedure can replace the time-consuming Ficoll stratification as cell recovering step. Here, we show a MRD comparison study using both total white blood cells and mononuclear cells recovered by the 2 procedures from 46 follicular lymphoma (FL), 15 multiple myeloma (MM), and 11 mantle cell lymphoma (MCL) patients enrolled in prospective clinical trials. RESULTS The experiments were performed in the 4 laboratories of the Fondazione Italiana Linfomi (FIL) MRD Network and showed superimposable results, in terms of good correlation (R = 0.87) of the MRD data obtained by recovering blood cells by the 2 approaches. CONCLUSION Based on these results, the FIL MRD Network suggests to optimize the pre-analytical phases introducing RBL approach for cell recovery in the clinical trials including MRD analysis.

Abstract
BACKGROUND A wide variety of meshes are available for surgical treatment of abdominal wall defects. These meshes are constructed with different materials with different biological properties. METHODS A prospective database was instituted (January 2009-December 2010) to register biological prostheses (BPs) implanted in Italy. RESULTS A total of 193 cases were registered. The mean age of the patients was 53.1 years (SD ±7.4). The ratio of males to females was 1.3 to 1. The mean body mass index was 28.2 (SD ±4.1). The breakdown of American Society of Anesthesiologists (ASA) scores was as follows: ASA I, 35.7%; ASA II, 27.5%; ASA III, 31.6%, and ASA IV, 5.2%. For ventral-incisional hernias, the mean duration of surgery was 101.1 min (SD ±25.3), while for inguinal-femoral hernias it was 49.2 min (SD ±19.1). The rate of urgent procedures was 36.7%. The surgical field was clean in 57.4% of cases, clean-contaminated in 21.3%, contaminated in 12.3% and dirty in 9%. Techniques used for inguinal-femoral hernias were as follows: Lichtenstein in 66.7%, plug and mesh in 3.8%, transabdominal-preperitoneal in 25.7% and intraperitoneal onlay mesh in 3.8%. The following prostheses were used: swine intestinal submucosa in 54.9%, porcine dermal collagen in 39.9% and bovine pericardium in 5.2%. In 45.1% of cases the prostheses were cross-linked. Techniques used for ventral-incisional hernias were as follows: onlay in 3.6%, inlay in 5.5%, sublay in 62.7% and underlay via laparoscopy in 28.2%. The mean overlap was 4.1 cm (SD ±1.2). No intestinal anastomosis was necessary in 65.3% of cases; however, small/large bowel resection and anastomoses were necessary in 22.3 and 12.4% of cases, respectively. Intraoperative blood transfusion was necessary in 10.4% of procedures. The skin was completely closed in 84% of procedures. At the 1-month follow-up, there were no complications in 54.4% of cases. Among the cases with complications, 10 patients (5.8%) experienced recurrence, and the postoperative readmission rate was 12.9%. The average visual analog scale (VAS) score for pain was 2.9 (SD ±1.2) at rest. At the 1-year follow-up, there were no complications in 96.4% of cases. Two patients experienced recurrence, and the postoperative readmission rate was 3.6%. The average VAS score for pain was 1.8 (SD ±0.8) at rest. CONCLUSIONS This register shows that BPs are highly versatile and can be used in either open or laparoscopic surgery in all kinds of patients and in contaminated surgical fields. However, due to the very good outcomes of synthetic meshes and the high costs of BPs, the latter should only be used in selected cases.

Abstract
BACKGROUND Chronic groin pain is defined as pain arising 3-6 months after inguinal hernia repair that can compromise the patient's quality of life. Many articles in the literature report clinical presentation, but there are no well-defined indications and protocols of treatment. METHODS Forty-six patients underwent surgical treatment for chronic groin pain that consisted of a simultaneous double approach, anterior and posterior, to the inguinal region, with 44 triple neurectomies and 2 iliohypogastric neurectomies. Ilio-inguinal and ilio-hypogastric nerves were resected by anterior approach, while genitofemoral trunk was resected by a posterior pre-peritoneal approach. Mesh was removed in 24 cases, and mesh and plug were removed in 16 cases. A new mesh repair was performed in 42 cases. All the patients were examined 1 week, 1 month and 1 year postoperatively. RESULTS In 40 patients, the surgical treatment has obtained good response with improvement or complete resolution of the pain. Two patients referred persistent groin pain different from preoperative and in 4 cases the pain persisted without substantial benefit. Mean VAS value was 7.89 before surgery and 1.89 after surgery. CONCLUSIONS Choice of the adequate therapy of chronic groin pain after inguinal hernia repair is still controversial. Our surgical approach turned out to be a safe and effective procedure. In this way, an accurate exploration of the whole inguinal region can be performed along with the identification of the nerves involved. Anyway in a certain number of cases, the resolution of pain cannot be achieved; this suggests a possible involvement of differences in the single personality and tolerances of pain in the different patients.

Abstract
BACKGROUND A combination of bortezomib (1.3 mg/m(2)), melphalan (5 mg/m(2)), and dexamethasone (40 mg) (BMD), with all three drugs given as a contemporary intravenous administration, was retrospectively evaluated. PATIENTS AND METHODS Fifty previously treated (median 2 previous lines) patients with myeloma (33 relapsed and 17 refractory) were assessed. The first 19 patients were treated with a twice-a-week (days 1, 4, 8, 11, 'base' schedule) administration while, in the remaining 31 patients, the three drugs were administered once a week (days 1, 8, 15, 22, 'weekly' schedule). RESULTS Side-effects were predictable and manageable, with prominent haematological toxicity, and a better toxic profile in 'weekly' schedule (36% versus 66% in 'base' schedule). The overall response rate was 62%. After median follow-up of 24.5 months (range 2.7-50 months), the median progression-free survival (PFS) was 21.6 with no difference between the two schedules and the median overall survival (OS) was 33.8 months. Independently from the adopted schedule, we found that also in a cohort of relapsed/refractory patients achieving at least partial remission improved PFS (35.2 versus 9 months) and OS (unreached median versus 18 months). CONCLUSION Taken together, our observations suggest that BMD is an effective regimen in advanced myeloma patients with acceptable toxicity.

Abstract
PURPOSE To investigate pain and other complications following inguinal hernioplasty performed by the Lichtenstein technique with mesh fixation by fibrin glue or sutures. METHODS Five hundred and twenty patients were enrolled in this 12-month observational multicenter study and received either sutures or fibrin glue (Tissucol(®)/Tisseel(®)) based on the preference of the surgeon. Pain, numbness, discomfort, recurrence, and other complications were assessed postoperatively and at 1, 3, 6, and 12 months. Pain intensity was assessed by a visual analog scale (VAS; 0 [no pain] to 10 [worst pain]). RESULTS One hundred and seventy-one patients received sutures and 349 received fibrin glue. During the early postoperative phase, 87.4% of patients in the fibrin glue group and 76.6% of patients in the sutures group were complication-free (P = 0.001). Patients who received fibrin glue were also less likely to experience hematoma/ecchymosis than those in the suture group (both P = 0.001). The mean pain score was significantly lower in the fibrin group than the sutures group (2.5 vs. 3.2, P < 0.001). At 1 month, significantly fewer patients in the fibrin glue group reported pain, numbness, and discomfort compared with patients in the sutures group (all P < 0.05). Fibrin glue patients also experienced less intense pain (0.6 vs. 1.2; P = 0.001). By 3 months, the between-group differences had disappeared, except for numbness, which was more prevalent in the sutures group. By 12 months, very few patients reported complications. CONCLUSIONS Tissucol fibrin glue for mesh fixation in the Lichtenstein repair of inguinal hernia shows advantages over sutures, including lower incidence of complications such as pain, numbness, and discomfort, and should be considered as a first-line option for mesh fixation in hernioplasty.

Abstract
We reviewed case reports, updated to January 2005, of 2,468 operations for groin hernia in 2,350 patients, including 277 recurrent hernias. The data obtained, following a simple anatomo-clinical classification into three types that could be used to orient surgical strategy, were: type R1--first recurrence of "high" oblique external reducible hernia with small (<2 cm) defect in non-obese patients after pure tissue or mesh repair; type R2--first recurrence of "low" direct reducible hernia with small (<2 cm) defect in non-obese patients after pure tissue or mesh repair; and type R3--all other recurrences, including femoral recurrences, recurrent groin hernia with large defect (inguinal eventration), multi-recurrent hernias, non-reducible contralateral primary or recurrent hernia, and situations compromised by aggravating factors (e.g. obesity) or otherwise not easily included in R1 or R2 after pure tissue or mesh repair.

Abstract
We report on the inhibitory activity of the NSAIDs meloxicam, carprofen, phenylbutazone and flunixin, on blood cyclooxygenases in the horse using in vitro enzyme-linked assays. As expected, comparison of IC50 indicated that meloxicam and carprofen are more selective inhibitors of COX-2 than phenylbutazone and flunixin; meloxicam was the most advantageous for horses of four NSAIDs examined. However at IC80, phenylbutazone (+134.4%) and flunixin (+29.7%) had greater COX-2 selectivity than at IC50, and meloxicam (-41.2%) and carprofen (-12.9%) had lower COX-2 selectivity than at IC50. We therefore propose that the selectivity of NSAIDs should be assessed at the 80% as well as 50% inhibition level.

Abstract
The contractile effects of PGF2alpha and its cloprostenol analogs (D-enantiomer and racemate) were examined on isolated smooth muscle preparations (uterine, tracheal, ileal and arterial) from rat, guinea-pig and horse. DL- and D-cloprostenol were potent contractors of myometrium, but had negligible secondary effects on other types of smooth muscle, except artery whose response to the D-enantiomer may give rise to some concern.

Abstract
Despite assays on ring preparations in vitro confirmed that the vasoconstrictor sympathetic control in the horse common digital artery mainly depends on alpha(1)-adrenoceptors stimulation, selective alpha(2)-adrenoceptor agonists were investigated under the same experimental conditions. Both detomidine (DET) and UK 14304 differed from noradrenaline (NA) and phenylephrine (PHE) in provoking contractile effects which were slowly onsetting, concentrations-unrelated and unremovable by repeated washings. While prazosin (PRA) clearly antagonized the effects of NA and PHE, neither pre- nor post-treatments of the preparations with alpha(2)-antagonists succeeded in antagonizing or removing the effects of the two alpha(2)-agonists tested, which moreover were unaffectable either by lowering the organ bath temperature or by depriving the nutritive medium of Ca(2+). To explain this unusual behavior of alpha(2)-adrenoceptors stimulation it has been hypothesized that a Ca(2+) mobilization from the endoplasmic reticulum of the smooth muscle cell occurs which is followed by a hindered reuptake of them.

Abstract
BACKGROUND Para aminobenzoic acid (PABA) derivatives and cinnamate are chemical sunscreens that protect against UVB (290 to 320 nm). They may occasionally produce contact and photocontact sensitization. OBJECTIVE To report a sensitization to octyl-dimethyl-PABA and photosensitization to 2-ethylhexyl-p-metossicinnamate in a 31-year-old man. METHODS A patient with a 3-year history of a relapsing dermatitis involving the face, neck, legs, and knees is reported. The eruption had recurred every summer after sunlight exposure. Patch tests with International Contact Dermatitis Research Group (IC-DRG) standard series and the photopatch series (Hermal-Trolab, Reinbek, Germany) using Finn chambers on Scanpor (Norgesplaster A/S, Oslo, Norway) were carried out. RESULTS We found a positive reaction to Balsam of Peru, fragrance mix, Escalol 507, and Parsol MCX (Hermal-Trolab, Reinbek, Germany). Photopatch test revealed a positive reaction only for Parsol MCX. CONCLUSION The incidence of allergic contact dermatitis to sunscreens is considered low. Recently sunscreens patch test concentrations have been increased from 2% to 10%. These higher percentages will probably permit the identification of more cases of sunscreens allergy in the near future.

Abstract
The case of a 34-yr-old Caucasian male with Graves' disease presenting with a flaccid quadriplegia and severe hypokalemia is reported. The weakness was prevalent at the lower extremities and began during nocturnal sleep, after a strenuous physical exertion performed during the day. Correction of hypokalemia promptly reversed the quadriplegia. The occurrence of hypokalemic thyrotoxic periodic paralysis several months after the beginning of thyrotoxic symptoms, and the normal insulin serum levels on admission differentiate this patient from most of the previously reported cases.

Abstract
A technique whereby immune complexes (ICs) are detected in the CSF and serum from their inhibitory effect on the agglutination of IgG-coated latex particles by rheumatoid factor (RF) has been applied to patients with the following neurological diseases: multiple sclerosis (MS), inflammatory diseases, extradural peripheral neuropathies (EPN), CNS tumors, dementia, and a control group of other neurological diseases (OND). The groups did not differ significantly in respect of IC positivity either in CSF or serum. The MS group was tested for correlations between percentage of IC positives and CSF IgG/Albumin ratio on the one hand and presence of oligoclonal bands on isoelectric focusing on the other. The specificity of ICs to the dysimmune condition is discussed.

Abstract
Paroxysmal kinesigenic choreoathetosis is a rare disease of unknown origin, considered by some authors a reflex epilepsy, by some an extrapyramidal disorder and related recently to brainstem atrophy. Two patients, father and son, aged 52 and 22 years, are described suffering from this disease starting at age 40 and 13. In both patients the attacks consisted in slow flexion and extention movements starting in the foot and extending to the knee and the arm and were usually monolateral, but in the son some attacks were bilateral causing him to fall and involved also face muscles. In both patients neuroradiological investigations were normal. Neurophysiological studies including blink reflex, short latency somatosensory evoked potentials and brainstem acoustic evoked potentials did not show any involvement of the brainstem. In one case carbamazepine therapy, at low dosage, was tried and cured the patient.

Abstract
Forty right hemisphere-damaged patients and 35 normal controls were given five language tests, the Token test, a naming to description test, the Reporter's test, a word fluency test and a sentence anagram test. The sentence anagram test was the only measure on which right hemisphere patients performed significantly more poorly than control patients. It is surmised that this impairment may be indicative of a direct right hemisphere participation in linguistic performances.

Abstract
The treatment in vivo with anti-tumour drugs can induce an antigenic alteration of L1210 leukemia resulting in the rejection of an inoculum of 10 X 10(6) viable cells in syngeneic mice. As drug-induced antigens appeared in excess of any pre-existing tumour-associated transplantation antigens (TATA), viable altered cells have been used to sensitize syngeneic animals. Experiments showed that viable altered cells elicited stronger anti-TATA reaction than X-inactivated parental cells, as measured by host survival to a challenge of L1210 leukemia. TATA immunogenicity of parental cells has been preminent, in the strain of animals used, to determine the sensitizing effectiveness of 5-(3,3-dimethyl-1-triazeno)-imidazole-4-carboxamide (DTIC) cells. Host protection to an inoculum of parental tumours has been more proficient with the DTIC subline derived from highly immunogenic L1210Ha cells than from poorly immunogenic L1210Cr cells. Immunoprophylactic inocula, proper chemotherapeutic treatments and adoptive transfer of immune lymphocytes used in combination exerted a synergic host protection.
