Abstract
Disease-modifying therapies (DMT) administered to patients with multiple sclerosis (MS) can influence immune responses to SARS-CoV-2 and vaccine efficacy. However, data on the detailed phenotypic, functional and metabolic characteristics of antigen (Ag)-specific cells following the third dose of mRNA vaccine remain scarce. Here, using flow cytometry and 45-parameter mass cytometry, we broadly investigate the phenotype, function and the single-cell metabolic profile of SARS-CoV-2-specific T and B cells up to 8 months after the third dose of mRNA vaccine in a cohort of 94 patients with MS treated with different DMT, including cladribine, dimethyl fumarate, fingolimod, interferon, natalizumab, teriflunomide, rituximab or ocrelizumab. Almost all patients display functional immune response to SARS-CoV-2. Different metabolic profiles characterize antigen-specific-T and -B cell response in fingolimod- and natalizumab-treated patients, whose immune response differs from all the other MS treatments.

Abstract
Background The aim of this randomized clinical trial (RCT) was to compare immunological changes in virally suppressed people living with HIV (PLWH) switching from a three-drug regimen (3DR) to a two-drug regimen (2DR). Methods An open-label, prospective RCT enrolling PLWH receiving a 3DR who switched to bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) or dolutegravir/lamivudine (DTG/3TC) was performed. Blood was taken at baseline and months 6 and 12. The primary outcome was the change in CD4+ or CD8+ T-cell counts and CD4/CD8 ratio over time points. The secondary outcomes were the changes in immunological and inflammatory parameters. Parametric mixed-linear models with random intercepts and slopes were fitted separately for each marker after controlling for potential confounders. Results Between the two arms (33 PLWH each), there was no difference in CD4+ or CD8+ T cells, CD4/CD8 ratio, and IL-6 trajectories. PLWH switching to DTG/3TC had increased levels of both transitional memory and terminally differentiated CD4+ T cells (arm-time interaction p-value = 0.02) and to a lesser extent for the corresponding CD8+ T-cell subsets (p = 0.09). Significantly lower levels of non-classical monocytes were detected in the B/F/TAF arm at T6 (diff = -6.7 cells/mm3; 95% CI; -16, +2.6; p-value for interaction between arm and time = 0.03). All differences were attenuated at T12. Conclusion No evidence for a difference in absolute CD4+ and CD8+ T-cell counts, CD4/CD8 ratio, and IL-6 trajectories by study arm over 12 months was found. PLWH on DTG/3TC showed higher levels of terminally differentiated and exhausted CD4+ and CD8+ T lymphocytes and non-classical monocytes at T6. Further studies are warranted to better understand the clinical impact of our results. Clinical Trial Registration https://clinicaltrials.gov, identifier NCT04054089.

Abstract
Introduction A growing number of evidences suggest that the combination of hyperinflammation, dysregulated T and B cell response and cytokine storm play a major role in the immunopathogenesis of severe COVID-19. IL-6 is one of the main pro-inflammatory cytokines and its levels are increased during SARS-CoV-2 infection. Several observational and randomized studies demonstrated that tocilizumab, an IL-6R blocker, improves survival in critically ill patients both in infectious disease and intensive care units. However, despite transforming the treatment options for COVID-19, IL-6R inhibition is still ineffective in a fraction of patients. Methods In the present study, we investigated the impact of two doses of tocilizumab in patients with severe COVID-19 who responded or not to the treatment by analyzing a panel of cytokines, chemokines and other soluble factors, along with the composition of peripheral immune cells, paying a particular attention to T and B lymphocytes. Results We observed that, in comparison with non-responders, those who responded to tocilizumab had different levels of several cytokines and different T and B cells proportions before starting therapy. Moreover, in these patients, tocilizumab was further able to modify the landscape of the aforementioned soluble molecules and cellular markers. Conclusions We found that tocilizumab has pleiotropic effects and that clinical response to this drug remain heterogenous. Our data suggest that it is possible to identify patients who will respond to treatment and that the administration of tocilizumab is able to restore the immune balance through the re-establishment of different cell populations affected by SARS-COV-2 infection, highlighting the importance of temporal examination of the pathological features from the diagnosis.

Abstract
The formation of a robust long-term antigen (Ag)-specific memory, both humoral and cell-mediated, is created following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection or vaccination. Here, by using polychromatic flow cytometry and complex data analyses, we deeply investigated the magnitude, phenotype, and functionality of SARS-CoV-2-specific immune memory in two groups of healthy subjects after heterologous vaccination compared to a group of subjects who recovered from SARS-CoV-2 infection. We find that coronavirus disease 2019 (COVID-19) recovered patients show different long-term immunological profiles compared to those of donors who had been vaccinated with three doses. Vaccinated individuals display a skewed T helper (Th)1 Ag-specific T cell polarization and a higher percentage of Ag-specific and activated memory B cells expressing immunoglobulin (Ig)G compared to those of patients who recovered from severe COVID-19. Different polyfunctional properties characterize the two groups: recovered individuals show higher percentages of CD4+ T cells producing one or two cytokines simultaneously, while the vaccinated are distinguished by highly polyfunctional populations able to release four molecules, namely, CD107a, interferon (IFN)-γ, tumor necrosis factor (TNF), and interleukin (IL)-2. These data suggest that functional and phenotypic properties of SARS-CoV-2 adaptive immunity differ in recovered COVID-19 individuals and vaccinated ones.

Abstract
Immunological memory is the basis of protection against most pathogens. Long-living memory T and B cells able to respond to specific stimuli, as well as persistent antibodies in plasma and in other body fluids, are crucial for determining the efficacy of vaccination and for protecting from a second infection by a previously encountered pathogen. Antigen-specific cells are represented at a very low frequency in the blood, and indeed, they can be considered "rare events" present in the memory T-cell pool. Therefore, such events should be analyzed with careful attention. In the last 20 years, different methods, mostly based upon flow cytometry, have been developed to identify such rare antigen-specific cells, and the COVID-19 pandemic has given a dramatic impetus to characterize the immune response against the virus. In this regard, we know that the identification, enumeration, and characterization of SARS-CoV-2-specific T and B cells following infection and/or vaccination require i) the use of specific peptides and adequate co-stimuli, ii) the use of appropriate inhibitors to avoid nonspecific activation, iii) the setting of appropriate timing for stimulation, and iv) the choice of adequate markers and reagents to identify antigen-specific cells. Optimization of these procedures allows not only determination of the magnitude of SARS-CoV-2-specific responses but also a comparison of the effects of different combinations of vaccines or determination of the response provided by so-called "hybrid immunity," resulting from a combination of natural immunity and vaccine-generated immunity. Here, we present two methods that are largely used to monitor the response magnitude and phenotype of SARS-CoV-2-specific T and B cells by polychromatic flow cytometry, along with some tips that can be useful for the quantification of these rare events. © 2023 Wiley Periodicals LLC.

Abstract
Whole-body cryotherapy (WBC) consists of short exposure (up to 2–3 min) to dry air at cryogenic temperatures (up to -190 °C) and has recently been applied for muscle recovery after injury to reduce the inflammation process. We aimed to determine the impact of cryotherapy on immunological, hormonal, and metabolic responses in non-professional soccer players (NPSPs). Nine male NPSPs (age: 20 ± 2 years) who trained regularly over 5 consecutive days, immediately before and after each training session, were subjected to WBC treatment (WBC-t). Blood samples were collected for the evaluation of fifty analytes including hematologic parameters, serum chemistry, and hormone profiles. Monocytes phenotyping (Mo) was performed and plasmatic markers, usually increased during inflammation [CCL2, IL-18, free mitochondrial (mt)DNA] or with anti-inflammatory effects (IL2RA, IL1RN), were quantified. After WBC-t, we observed reduced levels of ferritin, mean corpuscular hemoglobin, mean platelet volume, testosterone, and estradiol, which however remain within the normal ranges. The percentage of the total, intermediates and non-classical Mo increased, while classical Mo decreased. CXCR4 expression decreased in each Mo subset. Plasma IL18 and IL2RA levels decreased, while IL1RN only exhibited a tendency to decrease and CCL2 showed a tendency to increase. Circulating mtDNA levels were not altered following WBC-t. The differences observed in monocyte subsets after WBC-t may be attributable to their redistribution into the surrounding tissue. Moreover, the decrease of CXCR4 in Mo subpopulations could be coherent with their differentiation process. Thus, WBC through yet unknown mechanisms could promote their differentiation having a role in tissue repair.

Abstract
Aging is a major risk factor for developing severe COVID-19, but few detailed data are available concerning immunological changes after infection in aged individuals. Here we describe main immune characteristics in 31 patients with severe SARS-CoV-2 infection who were >70 years old, compared to 33 subjects <60 years of age. Differences in plasma levels of 62 cytokines, landscape of peripheral blood mononuclear cells, T cell repertoire, transcriptome of central memory CD4+ T cells, specific antibodies are reported along with features of lung macrophages. Elderly subjects have higher levels of pro-inflammatory cytokines, more circulating plasmablasts, reduced plasmatic level of anti-S and anti-RBD IgG3 antibodies, lower proportions of central memory CD4+ T cells, more immature monocytes and CD56+ pro-inflammatory monocytes, lower percentages of circulating follicular helper T cells (cTfh), antigen-specific cTfh cells with a less activated transcriptomic profile, lung resident activated macrophages that promote collagen deposition and fibrosis. Our study underlines the importance of inflammation in the response to SARS-CoV-2 and suggests that inflammaging, coupled with the inability to mount a proper anti-viral response, could exacerbate disease severity and the worst clinical outcome in old patients. Patients over the age of 70 show inflammaging and a weaker anti-viral response to SARS-CoV-2, pointing at the immunological changes associated with COVID-19 severity and outcome for aged patients.

Abstract
Renal‐cell carcinoma (RCC) is responsible for the majority of tumors arising from the kidney parenchyma. Although a progressive improvement in median overall survival has been observed after the introduction of anti‐PD‐1 therapy, many patients do not benefit from this treatment. Therefore, we have investigated T cell dynamics to find immune modification induced by anti‐PD‐1 therapy. Here, we show that, after therapy, RCC patients (5 responders and 14 nonresponders) are characterized by a redistribution of different subsets across the memory T cell compartment.

Abstract
Although it is now widely accepted that host inflammatory response contributes to COVID-19 immunopathogenesis, the pathways and mechanisms driving disease severity and clinical outcome remain poorly understood. In the effort to identify key soluble mediators that characterize life-threatening COVID-19, we quantified 62 cytokines, chemokines and other factors involved in inflammation and immunity in plasma samples, collected at hospital admission, from 80 hospitalized patients with severe COVID-19 disease who were stratified on the basis of clinical outcome (mechanical ventilation or death by day 28). Our data confirm that age, as well as neutrophilia, lymphocytopenia, procalcitonin, D-dimer and lactate dehydrogenase are strongly associated with the risk of fatal COVID-19. In addition, we found that cytokines related to TH2 regulations (IL-4, IL-13, IL-33), cell metabolism (lep, lep-R) and interferons (IFNα, IFNβ, IFNγ) were also predictive of life-threatening COVID-19.

Abstract
To better understand the mechanisms at the basis of neutrophil functions during SARS-CoV-2, we studied patients with severe COVID-19 pneumonia. They had high blood proportion of degranulated neutrophils and elevated plasma levels of myeloperoxidase (MPO), elastase, and MPO-DNA complexes, which are typical markers of neutrophil extracellular traps (NET). Their neutrophils display dysfunctional mitochondria, defective oxidative burst, increased glycolysis, glycogen accumulation in the cytoplasm, and increase glycogenolysis. Hypoxia-inducible factor 1α (ΗΙF-1α) is stabilized in such cells, and it controls the level of glycogen phosphorylase L (PYGL), a key enzyme in glycogenolysis. Inhibiting PYGL abolishes the ability of neutrophils to produce NET. Patients displayed significant increases of plasma levels of molecules involved in the regulation of neutrophils' function including CCL2, CXCL10, CCL20, IL-18, IL-3, IL-6, G-CSF, GM-CSF, IFN-γ. Our data suggest that metabolic remodelling is vital for the formation of NET and for boosting neutrophil inflammatory response, thus, suggesting that modulating ΗΙF-1α or PYGL could represent a novel approach for innovative therapies.

Abstract
In patients infected by SARS-CoV-2 who experience an exaggerated inflammation leading to pneumonia, monocytes likely play a major role but have received poor attention. Thus, we analyzed peripheral blood monocytes from patients with COVID-19 pneumonia and found that these cells show signs of altered bioenergetics and mitochondrial dysfunction, had a reduced basal and maximal respiration, reduced spare respiratory capacity, and decreased proton leak. Basal extracellular acidification rate was also diminished, suggesting reduced capability to perform aerobic glycolysis. Although COVID-19 monocytes had a reduced ability to perform oxidative burst, they were still capable of producing TNF and IFN-γ in vitro. A significantly high amount of monocytes had depolarized mitochondria and abnormal mitochondrial ultrastructure. A redistribution of monocyte subsets, with a significant expansion of intermediate/pro-inflammatory cells, and high amounts of immature monocytes were found, along with a concomitant compression of classical monocytes, and an increased expression of inhibitory checkpoints like PD-1/PD-L1. High plasma levels of several inflammatory cytokines and chemokines, including GM-CSF, IL-18, CCL2, CXCL10, and osteopontin, finally confirm the importance of monocytes in COVID-19 immunopathogenesis.

Abstract
Studies on the interactions between SARS-CoV-2 and humoral immunity are fundamental to elaborate effective therapies including vaccines. We used polychromatic flow cytometry, coupled with unsupervised data analysis and principal component analysis (PCA), to interrogate B cells in untreated patients with COVID-19 pneumonia. COVID-19 patients displayed normal plasma levels of the main immunoglobulin classes, of antibodies against common antigens or against antigens present in common vaccines. However, we found a decreased number of total and naïve B cells, along with decreased percentages and numbers of memory switched and unswitched B cells. On the contrary, IgM+ and IgM- plasmablasts were significantly increased. In vitro cell activation revealed that B lymphocytes showed a normal proliferation index and number of dividing cells per cycle. PCA indicated that B-cell number, naive and memory B cells but not plasmablasts clustered with patients who were discharged, while plasma IgM level, C-reactive protein, D-dimer, and SOFA score with those who died. In patients with pneumonia, the derangement of the B-cell compartment could be one of the causes of the immunological failure to control SARS-Cov2, have a relevant influence on several pathways, organs and systems, and must be considered to develop vaccine strategies.

Abstract
The immune system of patients infected by SARS-CoV-2 is severely impaired. Detailed investigation of T cells and cytokine production in patients affected by COVID-19 pneumonia are urgently required. Here we show that, compared with healthy controls, COVID-19 patients' T cell compartment displays several alterations involving naïve, central memory, effector memory and terminally differentiated cells, as well as regulatory T cells and PD1+CD57+ exhausted T cells. Significant alterations exist also in several lineage-specifying transcription factors and chemokine receptors. Terminally differentiated T cells from patients proliferate less than those from healthy controls, whereas their mitochondria functionality is similar in CD4+ T cells from both groups. Patients display significant increases of proinflammatory or anti-inflammatory cytokines, including T helper type-1 and type-2 cytokines, chemokines and galectins; their lymphocytes produce more tumor necrosis factor (TNF), interferon-γ, interleukin (IL)-2 and IL-17, with the last observation implying that blocking IL-17 could provide a novel therapeutic strategy for COVID-19.

Abstract
The pandemic caused by severe acute respiratory syndrome coronavirus 2 heavily involves all those working in a laboratory. Samples from known infected patients or donors who are considered healthy can arrive, and a colleague might be asymptomatic but able to transmit the virus. Working in a clinical laboratory is posing several safety challenges. Few years ago, International Society for Advancement of Cytometry published guidelines to safely analyze and sort human samples that were revised in these days. We describe the procedures that we have been following since the first patient appeared in Italy, which have only slightly modified our standard one, being all human samples associated with risks. © 2020 International Society for Advancement of Cytometry.

Abstract
Introduction: The activity and regulation of inflammasome is receiving increasing attention in septic shock. Moreover, there is a growing body of evidence suggesting that mitochondrial DNA (mtDNA) can play a role as biomarker of disease severity and even mortality both in adults and children in critically ill setting. However, no data are available on the amount of circulating mtDNA and inflammasome gene expression in multi-drug resistant (MDR) bacteria septic shock. For this reason, the aim of this study was to determine whether plasma mtDNA levels and inflammasome gene expression in monocytes could be related to severity in patients admitted to intensive care unit (ICU) with septic shock due to MDR pathogens. Materials and Methods: Peripheral blood mononuclear cells (PBMC) and plasma were isolated from up to 20 ml of venous blood by density gradient centrifugation in patients admitted to ICU with the diagnosis of septic shock due to MDR-bacteria. Then, CD14+ monocytes were sorted, and RNA and DNA were extracted. NLRP3, PYCARD, AIM2 and NAIP expression level was analyzed by RT-PCR. Plasma circulating mtDNA levels were quantified by digital droplet PCR. Basal and outcome characteristics of the patients were collected. Age-matched healthy subjects were chosen as controls. Results: Nineteen patients with septic shock and 20 healthy subjects were enrolled in the study. A small trend toward an increased expression of inflammasome genes was observed in septic shock patients, who also displayed a marked tendency to an increased expression of IL-18 and IL-1β genes. Circulating mtDNA levels were significantly higher in septic shock patients if compared to healthy subjects, and patients who died in ICU were characterized by higher level of mtDNA if compared to those who were dismissed after 7 days. No correlations were found between mtDNA and inflammasome level and other clinical variables. Conclusion: Despite many limitations, our data suggest that in patients with septic shock caused by MDR pathogens the expression of main inflammasome genes was comparable to that of healthy patients without infection. Furthermore, our data evidence a possible role of mtDNA as a prognostic marker of severity in septic shock from MDR.

Abstract
BACKGROUND Macrodontia is a rare dental anomaly, and isolated macrodontia is even more infrequent. The aim of this article is to report on a young male patient with macrodontia of the mandibular premolars. CASE REPORT We herein present a case report of a young male patient receiving pharmacological growth hormone therapy for 10 years, who was diagnosed with macrodontia of the mandibular premolars. The patient underwent surgical treatment at the School of Dentistry of the University of Buenos Aires and was followed-up for more than 3 years. CONCLUSION Macrodontia is a rare condition. Early diagnosis and treatment of this anomaly favors adequate formation of the dental arches. In the light of this case report, a review of paediatric patients who received growth hormone therapy during the tooth formation stage would seem relevant.

Abstract
Landfills in Venezuela have serious problems regarding their location, design and operation. In fact, basic waste disposal is one of the main weaknesses of the municipal waste management in this country. The Venezuelan Ministry of Environment and Renewable Resources has studied and identified the negative impacts of operating landfills, but no program has been implemented to determine the cause-effect relation of these impacts or to design strategies to counteract with the serious environmental and health risks generated. This paper describes how EVIAVE methodology can be successfully used for landfill diagnosis, and shows how this type of landfill diagnosis was applied in Venezuela. For our research study, we carried out both a quantitative and qualitative evaluation of the environmental problems generated by 22 landfills in Venezuela. Our study was based on the following environmental indexes: Landfill Environment, Environmental Risk, Environmental Value, and Probability of Contamination. For the purposes of our study, it was first necessary to adapt EVIAVE to the legal system and social context in Venezuela. The results obtained confirmed the applicability of this methodology to Venezuelan landfills. EVIAVE was found to be an effective planning tool that provided crucial information for the development of action plans, which would improve landfill operation, and help make decisions pertaining to their closure, sealing and eventual recovery.

Abstract
AIMS We must pay attention to character formation of Medical Doctors because it could build a good or bad relationship with colleagues and patients: it is not a merely "humanistic" goal but a necessary component of professional excellence. The first endpoint of this study is to identify how to improve the quality of the outpatient visit. MATERIALS AND METHODS We tested a user-friendly questionnaire, distributed to 100 patients. RESULTS AND CONCLUSIONS The most important behavioral characteristics desired by patients from physicians are: 1. to have the physician's attention without feeling hurried (such as without the physician answering a phone call during the office visit); 2. to have continuity of care even in the ambulatory setting; 3. to find a relationship of empathy, participation and sharing; 4. to have a peaceful relationship of collaboration with the nurses and other health care personnel; 5. to find the physician appropriately groomed and dressed; 6. to receive the full diagnosis with clarity and at the most appropriate moment of communication.

Abstract
A multidisciplinary study was conducted on water from two rivers in the Abruzzo region of Italy. The study highlighted the importance of histopathological investigations in the evaluation of the environmental impact on fish. Brown trout (Salmo trutta fario) from the Aterno river and chub (Leuciscus cephalus) from the Vomano river were sampled in winter and then again in spring. Histopathological investigations of gills, kidneys and livers revealed inflammatory and degenerative lesions, early warning signals of environmental stress. Lesions were evaluated semi-quantitatively and findings were ranked. The histopathological features were compared with results obtained from the analysis of water samples and macroinvertebrates collected in the two rivers (extended biotic index). All results confirmed alterations of the environment.

Abstract
Photobacterium damsela subsp. piscicida (Phdp) is the aetiological agent of fish pasteurellosis, causing heavy losses in intensive mariculture plants. The present work compares the protective efficacy of five different vaccine formulation: oral, intraperitoneal, immersion, bivalent immersion (Vibrio anguillarum) and immersion associated with immunostimulants. Each of these vaccine formulations containing whole cells of Phdp formalin inactivated (FKC), was administered to 100 sea bass weighing approximately 2 g; 100 non-vaccinated sea bass were used as controls. Protection against pasteurellosis was tested for 40 days after vaccination by intraperitoneal challenge: each fish was inoculated with Phdp cells at a concentration of 2.75 x 10(4) cfu/ml. Mortality was recorded over the following 14 days, vaccine protection was evaluated using a relative percentage survival (RPS) index. The intraperitoneal formulation gave excellent protection (RPS 82.4%). The most effective immersion form was that followed by simple immersion (RPS 23.1%) followed by the group vaccinated with bivalent vaccine (RPS 18.7%). Protection conferred orally (RPS 28.6%) is of interest for practical purposes.

Abstract
After a careful revision of the various papers and on the basis of their personal experience, the persons responsible for this project analyse the factors that, today, influence the development of an adenocarcinoma in the region of the gastro-esophageal junction. They also study therapeutic strategies on the basis of new findings in anatomic-physiological matters of this region. From this analysis, specialists notice an increase in adenocarcinomas which affect the gastric region of the cardia, in comparison with carcinomas which affects the gastric region in toto. By considering Barrett, Hayward, Riedel and Ruol's studies, they maintain that the fundamental factor which causes the development of cardial adenocarcinoma is the gastroesophageal reflux. This reflux acts as a chronic irritative stimulus on the esophageal wall and therefore it provokes an increase in mucous secretion and the formation of metaplasia. This metaplasia is initially mucosecreting, acid-secreting and in the end it becomes intestinal. This also leads to the appearance of absorbent calciform cells; the absorption of toxic or mutagenic substance for the cell itself, will be the next step for the development of an adenocarcinoma. Nowadays the therapy of intestinal metaplasia provides for different therapeutic levels: from the endoscopic monitoring (which is used for the most serious cases of dysplasia), to the PPI medical treatment(today in disuse), to the surgical laparoscopic treatment with non-refluxing plasty (Nissen, Toupet). This last treatment is today associated with endoscopic esophageal mucosectomy in order to achieve a better effectiveness. This happens through the use of various methodologies, for example the multipolar electrocoagulation.

Abstract
BACKGROUND Until now therapy of carcinoma of the esophagus has presented an aura of pessimism, resulting in an attitude among physicians that cure was impossible. Presently the overall 5-year survival is between 38.3% and 55% thanks to new radical surgical techniques. The aim of this work is to evaluate lymph node dissection in treatment of esophageal carcinoma by analyzing morbidity, mortality, survival and quality of life. METHODS From 1975 to 1995, 170 patients with carcinoma of the esophagus and cardia underwent operation, of whom 165 underwent 2-field lymphadenectomy and four 3-field lymphadenectomy; one patient was submitted to self-transplanting jejunal loop to neck. One hundred and twenty-two patients had standard resection and 47 en bloc resection. RESULTS Lymph node involvement is often found in patients with superficial carcinoma and it greatly influences outcome after esophagectomy. In 2-field lymphadenectomy morbidity and mortality are more frequent in en bloc resections; global 3-year survival was better in patients with early lesions. Three-field lymphadenectomy was performed in only few cases, not sufficient to express a definitive opinion. CONCLUSIONS On the basis of our experience, we conclude that the better survival is particularly dependent on early diagnosis, histological type of neoplasia and following surgical treatment, especially on the type of resection with 2 or 3-field lymphadenectomy.

Abstract
Lung surgery in the elderly, once considered a major risk, to be avoided if possible has become more popular in recent years as a result of many factors. First: lung cancer incidence has increased significantly in every age group but mostly in the elderly. Second: diagnosis at an early stage of the disease is higher in patients over 70 due to more frequent medical control in old subjects. Third: we now have more and more humans over 80 and a life expectancy increasing over the years. Fourth: preoperative, operative and postoperative medical supports are now safer and more reliable than previously. Operability criteria in the elderly are substantially the same as in younger group of patients for lung cancer. There are no reasons to refuse surgery in a subject over 80 because he is old. Lobectomy is the procedure of choice for lung cancer even in the elderly. Pneumonectomy must be avoided preferring a less radical procedure (wedge resection) so avoiding the risk of a postoperative respiratory failure that is often fatal for a patient with in border line functional respiratory tests, as often happens in the elderly. Thoracoscopic atypical resections must be considered in patients when a wedge resection is indicated preoperatively and almost always metastatic pulmonary lesion.

Abstract
Thyroid microcarcinomas (TMC) are histologically malignant diseases, despite their limited dimensions and non-aggressive behaviour; frequent multifocality of the disease and local recurrence is really possible after conservative resection. Modern therapeutic approaches to thyroid microcarcinoma include both radical surgical treatment, influenced by the frequent locoregional diffusion of TMC, consisting of a total thyroidectomy with an eventual central and/or functional unilateral lymphadenectomy, depending on the clinical evidence of lymh node metastases and conservative treatment based on more limited resections which take into account the slow clinical progression of this type of tumour. The aim of our work is to examine the therapeutic guidelines for surgical treatment of TMC which, in our experience, are closely dependent on clinical presentation type. From 1991 to 2000, more than 400 patients with thyroid disease were referred to the Department of Surgical Science and Applied Medical Technologies "F. Durante". Threehundred-seventythree patients received surgical treatment: in 311 patients a benign disease was diagnosed, while in 62 neoplasia was present. In total we observed 30 TMC, consisting of 28 papillary and 2 follicular microcarcinomas. On the basis of clinical presentation we divided patients in three groups: A--patients with a clinically suspicious neoplastic lesion before surgical treatment; B--patients in whom histological diagnosis of cancer was "incidental" after an operation performed for benign disease; C--patients in whom a neck lymph node metastases were clinically found before diagnosis of an "occult" papillary carcinoma in the thyroid gland. 27 total thyroidectomies and 3 conservative resections, that required successive total exeresis, were performed. In 5 cases a central neck lymph node dissection was carried out and in 5 + 1 cases functional modified lateral neck dissections was deemed necessary. Our data suggest that an evaluation of tumor's malignancy cannot be carried out on the basis of its dimensions alone. Indeed, biological aggressivity, whether local or at a distance, is a prerogative of both large and small tumours. Therefore a microcarcinoma must be considered a full-blown form of thyroid cancer and as such must be treated. Total thyroidectomy may be followed by identification of possible local metastases. "Whole body" scintigraphy allows to identify and treat with radioiodine therapy, possible recurrent lesions. Therefore in conclusion, total resection is not only a useful, but also a necessary treatment for the correct diagnostic and therapeutic follow-up of these patients.

Abstract
A case report of a 44 year-old white man admitted to the surgical unit for a bilateral simultaneous pneumothorax is presented. The pneumothorax occurred on day one after a surgical operation for discal hernia; in the past the patient already presented a right spontaneous pneumothorax at 32 years of age and a left pneumothorax at 37 years of age, both treated with a pleural drainage. A thoracic drain was bilaterally positioned with a good result only in the right side. The persistence of the left pneumothorax induced the authors to perform a postero-lateral thoracotomy bullae excision and pleurectomy with a good postoperative course. After a few months a new right pneumothorax occurred and the patient was treated with a right postero-lateral thoracotomy, bullae resection and pleurectomy. On the basis of the case reported, the authors consider the different opportunities in the treatment of spontaneous pneumothorax in relation to the present knowledges and technologies. Surgical procedure is to be preferred in case of persistence of pneumothorax despite a pleural drain and in case of pneumothorax in high risk subjects. Even if thoracoscopy seems to give better results regarding postoperative pain, it is not always possible with such a method to perform a careful pleurectomy neither to obtain it in all cases (above all in secondary pneumothorax). Every case must then be carefully studied to choose the best treatment at present available.

Abstract
BACKGROUND Duodeno gastric reflux (DGR) is still a not well-defined condition, even though it has been the subject of different studies for many years. METHODS The authors examine its relation with gallstones before and after the surgical removal of the gallbladder. After examining various study techniques, they present their experience of DRG. In this work the methodology used in a group of 40 patients suffering from gallstones and operated by laparotomic cholecystectomy is presented. All patients have been subjected to a clinical questionnaire in order to evaluate their symptoms, before and after cholecystectomy, and at the same time they have been subjected to an endoscopic exam. It s not easy to comment the RESULTS. RESULTS Actually, of 32 patients (80%) showing DGR symptoms before surgical treatment, 20 showed their persistence, worsening, or the appearance of new symptoms after cholecystectomy, while 12 were completely asymptomatic. Of 8 patients with no symptoms before cholecystectomy, 3 developed a typical DGR symptomatology while 5 were asymptomatic. CONCLUSIONS So 57% of patients were DGR symptomatic after surgical treatment. The compromised function of cholecystitis with calculi, antrum-pyloric-duodenal motility, continuous bile flux in the duodenum, surgical trauma all interact in determining DGR.

Abstract
BACKGROUND The authors analyse gastroduodenal reflux (GDR) in the light of the progress made over the past ten years. The good results achieved using mini-invasive techniques in cholecystectomy prompted the authors to compare laparotomic and laparoscopic cholecystectomy in order to evaluate the influence of both techniques in determining GDR and clinical symptoms. METHODS Symptoms were evaluated before and after surgery in 30 patients operated using a laparotomic technique and in 30 patients operated using a laparoscopic technique. Two groups of 10 patients, operated respectively using laparotomic and laparoscopic techniques, were studied both clinically and endoscopically before and after surgery. RESULTS The analysis of the results shows a lower incidence of GDR and typical symptoms of GDR in patients undergoing laparoscopic surgery. The rationale underlying the lower incidence of GDR and its symptoms in these patients compared to the more conventional group is not completely clear. CONCLUSIONS These results may be influenced by reduced surgical trauma and the careful selection of case or the laparoscopic technique, hence the exclusion of cases complicated by severe cholecystitis.

Abstract
The authors report their study on gastro-esophageal reflux disease, a pathology that has become increasingly common over the past years reflecting both a real increase and the use of new and more sophisticated and reliable diagnostic methods and tests. It can be included in the group of pathologies absorbing the largest proportion of financial resources, even exceeding biliary lithiasic disease according to American studies. The authors start by analysing the symptoms of gastroesophageal reflux disease, drawing a distinction between typical (heartburn, epigastric pain and postprandial regurgitation) and atypical symptoms (laryngotracheal symptoms, bronchopulmonary symptoms and esophageal motor incoordination). They outline the diagnostic iter and tests most widely used today to achieve a correct diagnosis. Lastly, they report their experience of 160 patients attending their esophageal diagnostic unit since January 1999 who underwent a number of different instrumental tests, the results of which are compared. Three different aspects are compared: the presence of symptoms, 24-hour pH-metry and endoscopic tests. All these are necessary for a correct diagnosis of gastroesophageal reflux disease and to evaluate the possibility and efficacy of surgery. They emphasise the diagnostic importance of 24-hour pH-measurement as the only test that can directly reveal gastroesophageal reflux. Positive pH results represent a discriminating element in deciding whether the patient should undergo surgery.

Abstract
The A.A. present a case report of retroperitoneal spontaneous hematoma and put in evidence the difficulties in making an etiopathogenetic diagnosis of spontaneous renal cyst rupture. The patient was a 72 years old man admitted to the hospital in emergency for a painful ipogastric syntomatology and biliary vomit. The ecography showed a distanced gallbladder and the endoscopy evidenced a duodenal stenosis with compression of the gastric posterior wall, so that we were initially directed towards a pancreatic tumor even if the modest increase of the serum bilirubinemy and mostly the fact that direct component was almost normal, gave us strong doubts. The spiral TC gave finally the diagnosis of retroperitoneal hematoma and the presence of a bilateral polycystic kidney with several subcapsular cyst, let us suggest, as well as the anamnestic report of a physical stress, a renal origin of the bleeding. A wild literature review did not evidence other similar cases, but the ecclusion of other possible causes of retroperitoneal hematoma, suggested this conclusion.

Abstract
A type of malignant neoplasm of not frequent observation is reported and the difficulties concerning the distinction from the benign counterpart are underlined, for which a detailed instrumental study is made necessary, integrated with pre and, above all, postoperative histologic analysis. A white male patient of 83, affected by plurirecidivant chondromyxoma of the rib, was admitted for local recurrence. The lesion objectively appeared not dissimilar from the preceding ones, as an ovalar mass fixed on the underlying plains. Radiologic and ultrasonographic examinations seemed to confirm the admission diagnosis; at the end the patient underwent a new intervention. Histologic examination of the lesion yielded a diagnosis of chondromyxosarcoma. The clinical case is made even more interesting by the finding, through the TC technique, preoperatively performed, of a metastatic repetition on the opposite side. The authors examine the problem of the early recognition of a malignant neoplasm developing, in a patient with a clinical history of recidival chondromyxoma. Physical examination and laboratory analysis are not useful in the assessment of the occurring transformation. At molecular level chondromyxosarcoma is characterized by several genomic rearrangements and mutations. Though primitive chondromyxosarcoma often involves the ribs, chondromyxoma's transformation into its malignant counterpart is not a common event. The development of distant metastasis characterizes long term cases. Given the lack of encouraging results about chemo and radio-therapy efficacy in influencing the natural course of the disease, a systematic approach will be made necessary in patient management.

Abstract
The authors present a case report of an intestinal obstruction due to a relatively big coprolite migrated from a large Meckel's diverticulum to the distal Ileum. The patients apparently healthy and a vegetarian, complained on admission of the absence of emission of faeces and gas since four days before with noticeable abdominal distension. In the physical examination he presented intestinal meteorism, a hard abdomen, painful on deep palpation in the median quadrants, especially in the epigastric and mesogastric ones. The abdominal X-RAY in the standing position confirms: an occlusive state with numerous liquid levels in the Ileum. Because of a worsening of the symptomatology and the appearance of generalized comprimission, two days later an exploratory laparotomy was performed. The intervention showed the presence of a Meckel's diverticulum with approximately 10 cm in length, with an ample neck, the distal Ileum for approximately 15 cm in dilation returned rapidly to a normal calibre, after a pastous endoluminal formation borne in the Meckel's diverticulum (Meckel resection presented actually a large niche at the fundus level with a eroded wall) and migrated in the distal Ileum where it could cause the obstruction. In the present case it is probably useful to perform a preoperative CT scan in order to get a precise etiology and perform an ascending Colonscopy, so avoiding a surgical procedure. According to the authors a CT scan is indicated in all cases of intestinal occlusion of unknown case, in order to have a more precise definition of the physiopathology of the occlusion.

Abstract
BACKGROUND The surgical treatment of large wall defects conventionally defined as an extension over 10 cm is discussed. The difficulty to contain the bowels that have lost law of domicile in the abdominal hollow, constitutes motive for notable increase of the endo-abdominal Pressure with serious consequences in the postoperative course and this leads to the use of prothesis meshes that allow the closing of the abdominal hollow with the Tension-Free technique. METHODS Personal experience embraces 45 patients, with large wall defects, divided into 21 patients with overumbilical location, 14 with umbilical location, 10 with periumbelical location; a simple suture has been used in 7 cases, the reconstruction of the wall according to Stoppa in 36 cases and the apposition of Goretex net internally and Marlex net externally in 2 cases. RESULTS There have been neither mortality, neither recidivists of illness, but only some complications: 9 cases of superficial infection, 1 case of intestinal occlusion and 2 of subcutaneous seroma. CONCLUSIONS According to their experience and wide literature review, the authors draw some conclusions: an accurate toilet and a careful evaluation of the respiratory functionality are fundamental; it's necessary to postpone surgical intervention in presence of local inflammation and, where this is improrogable it's opportune to avoid the use of prothesis meshes or refold on readsorbible prothesis; special care must be taken to the hemostasis and an aspirative drain for 24-48 hrs preserves from the risk of postoperative hematomas and following local infections. The submuscular mesh permits a Tension-Free suture and for this reason it would have nowdays a more extensive use. Finally it's pointed out the choice of a PTFEe mesh in contact with the intestinal skein.

Abstract
Purpose of the paper is to sum up the problem of surgery of idiopathic varicocele according to the present possibilities, both surgical and sclerotic. A wide review of the literature underlines a high rate of relapses and persistence of the disease (with a percentage from 10 to and 10%) following the two most used technique: retrograde sclerotic therapy under radioscopic control and surgical retroperitoneal or inguinal ligature of the internal spermatic vein; this technique was preferred by us until 1997. The percentage of failures, high with reference to the benign form of the disease (over 10% in our series of more than 100 patients submitted to clinical and flow-meter examinations) let the authors suggest a combined and simultaneous operation of ligature both internal and external of the spermatic vein at the level of the internal inguinal ring. Anatomical reasons confirm the opportunity of this procedure since the involvement of the system of the external spermatic vein is present in about the 20% of the cases of idiopathic varicocele in accordance with various flebografic studies. The possibility of escape through the external spermatic vein is eliminated in the case in which such vessel is preserved, and it seems frequent above all in 3rd degree idiopathic varicocele where many anastomotic vessels between the two systems are present. This procedure can be made both in general or local anaesthesia, it doesn't involve postoperative hospital stay and present the same acceptable postoperative complication of other proposed operations. The laparoscopic treatment even if easily performed at the level of the internal inguinal ring, doesn't seem justified for the higher cost and equal compliance for the patient. Besides, it is not possible to proceed laparoscopically under local anaesthesia.

Abstract
In the carcinoid tumours of the bronchopulmonary tract surgical resection is still the primary goal. Many problems are, however, unclear: the extent of resection, formal lymph node dissection or not, the role of Video-Assisted Thoracic Surgery (VATS) and of the multidisciplinary approach. In the Department of Surgical Sciences and Applied Medical Technologies, "La Sapienza", Rome's University, from 1969 to 1994, we observed 18 patients with carcinoid tumours of the lung: 13 typical carcinoid (TC) and 5 atypical carcinoid (AC). In our series, the choice of therapeutic procedure was made on the basis of histological criteria and TNM classification. We performed 3 conservative and 10 extensive resections on typical carcinoid and 5 extensive resections on atypical carcinoid tumours. In our series VATS played a minor therapeutic role. Formal lymph node dissection was carried out on all our patients except in the cases of those with typical carcinoid tumours without enlarged hilar and mediastinal lymph nodes. The efficacy of adjuvant chemotherapy in carcinoid tumours treatment is controversial and will be confirmed by further trials. In bronchial carcinoid tumours the long-term prognosis is excellent. In our series the ten-year survival rate is 77 per cent in typical carcinoid and 40 per cent in atypical carcinoid cases.

Abstract
The authors report their surgical experience relating to dysphagic diseases of the esophagus (349 cases). In the light of these results, they describe the different surgical techniques used in the various pathologies: 1) Esophageal diverticula: The value of a careful evaluation of subdiverticular spasm is emphasised using preoperative manometry in cervical and epiphrenic diverticula, leading to subdiverticular myotomy when present. 2) esophageal achalasia and intermediate motor disorder: A clear difference must be drawn between these two diseases owing to the different motor behaviour of the esophagus. Dilatation of the LES is only useful in intermediate motor disorder and should be avoided in esophageal achalasia where a gastroesophageal reflux is produced if dilatation fails. Intraoperative manometry is very useful during the extramucosa myotomy phases as an indication of the complete removal of the sphincteric barrier, thus avoiding the risk of persisting disease. 3) Non-neoplastic stenosis. In primary stenosis (caused by caustic agents, primary GER or associated with JE) a conservative approach is advisable, whereas in iatrogenic stenosis (mainly linked to dilatation or cardiac surgery), owing to the anatomic complexity of the esophagogastric junction, a more radical approach is often required in the form of esophagogastric resection or even sub-total esophagectomy. 4) Neoplastic stenosis: Leiomyomas, although unusual, represent a clear indication for thoracoscopic access, provided that the dimensions allow it. Esophageal cancers represent a major surgical problem. A radical approach is represented by TE and the subsequent use of the stomach, or more rarely, the colon to reconstruct the alimentary tract. In spite of the very low resectability rate owing to locoregional spreading, until recently palliative surgery was essential to allow patients to eat. The introduction of autoexpanding prostheses, positioned using endoscopic methods, has provided a better solution to this problem.

Abstract
In the last twenty years, medical studies have reported a significant increase in thyroid neoplasms among patients with hyperthyroidism. Aim of the present work is to reconsider the real incidence of this not uncommon association and to establish a model for surgical treatment of hyperthyroidism for a possible concurrence with thyroid carcinoma. At the Department of Surgical Sciences and Applied Medical Technologies "La Sapienza" Rome's University, during the period 1994 to 1999, an homogeneous group of 82 patients was surgically treated for hyperthyroidism. Of our patients, fifty-four (66%) had a "multinodular toxic goiter" (MTG), twenty (24%) a "functional autonomous nodule" (FAN) while the remaining patients were affected by Graves' disease. The surgical procedures adopted were: 1) total extracapsular ipsilateral lobectomies and isthmectomies in sixteen patients with FAN; 2) total extracapsular thyroidectomy in all patients with MTG and with Graves' disease and in the remaining four patients with FAN after a long time treatment with thyrostatic drugs. On six (7%) of our patients we found out a thyroid carcinoma: five with MTG and one with Graves' disease. However, no association with thyroid carcinoma was observed in anyone with FAN. The correct treatment of thyroid surgical diseases is a single definitive operative approach. The procedure must be a total thyroidectomy in MTG and Graves' disease. However, in patients with FAN it's possible, after careful evaluation, to carry out a total extracapsular ipsilateral lobectomy with isthmectomy, justified by the normal morphology of the remaining thyroid tissue. It is always possible, in these cases, a subsequent complete exeresis if a carcinoma is present in the removed lobe.

Abstract
Primary motor disorders of LES causing dysphagia consist in cardial achalasia and intermedius motor disorder (IMD), the last one different from achalasia because of normal motor pattern of the esophageal body. In this paper diagnostic and therapeutic procedures are examined according to an experience of 94 surgically treated cases (22 rioperations for surgical failures). Cardial dilatation as treatment of choice is recognized only for IMD in which a normal peristaltic behaviour of the esophagus can avoid the high danger of GER. Surgical procedure, now laparoscopically performed, consisting in Heller's myotomy + Dor partial fundoplication is to be preferred in cases of true achalasia.

Abstract
This report is of 26 patients diagnosed with microcytoma of the lung in stages I, II, and IIIa. All patients received surgical treatment as well as postoperative chemoradiotherapy when indicated by stage. Mean survival rates were 16 months for stage 1, 10 months for stage II and 6 months for stage IIIa disease. For many years surgery was considered contraindicated in the treatment of pulmonary microcytoma. Now a multidisciplinary approach is being used in which surgery has a crucial role. Microcytoma of the lung has a poor prognosis due to its early metastasis and rapid growth. It is crucial to have early diagnosis and accurate, consistent staging as the basis for treatment. A review of literature shows that the use of surgery, chemotherapy and radiotherapy are all important in treatment of microcytoma. Chemotherapy is successfully utilized preoperatively to improve local control, decrease neoplastic mass, induce histological regression and as postoperative adjuvant therapy. Radiotherapy has been shown to be effective preoperatively to reduce local mass and prophylactically for cerebral metastasis. Surgery is crucial to irradicate the neoplastic mass, improve staging accuracy, decrease the possible selection of neoplastic clones resistant to postoperative therapy, decrease local recurrence and allow less aggressive chemoradiotherapy. We feel the most effective protocol for pulmonary microcytoma includes preoperative chemotherapy and radiotherapy when indicated followed by surgical intervention and finally successive adjuvant therapy. The limited number of our cases does not consent a statistically significative conclusion. Our data confirm the importance of the surgical procedure in stages I and II, where according also to other authors, the best results are obtained. Surgical indication in stage IIIa is still discussed due to precocius lymphnode dissemination that significantly affects long-term survival.

Abstract
Both surgery and dilatation are useful for the treatment of cardial achalasia. The authors make a wide review of the literature with particular attention to reports comparing results of these procedures. This review evidences that surgery gives better results than dilatations (84.4% of good results with surgery against 71.4% with repeated dilatations) and is certainly more stable over the years. Mini-invasive surgery points out even more strongly that surgery is nowadays to be preferred. Laparoscopy makes it possible to avoid postoperative pain, to discharge the patient in a couple of days and finally to eliminate surgical scars. Complications, even more frequent after surgery (5.5% against 2.1% of dilatation) are still acceptable in number and not heavy in quality.

Abstract
From 1973 to 1994, 21 patients with esophageal peptic stenosis were submitted to esophago-jejuno-gastroplasty with Merendino's technique. In 14 cases peptic stenosis developed after Heller's myotomy for achalasia, associated in 3 cases with fundoplication. In 3 patients the stenosis was secondary to fundoplication. Other 3 subjects presented a primary stenosis. One patient showed Barrett's esophagus with in situ carcinoma. Endoscopic esophageal dilatation was attempted in every patient with no satisfactory results. One patient died for a postoperative cardiopulmonary failure (4.7%). One patient developed a fistula of the esophago-jejunal anastomosis treated with enteral nutrition successfully (4.7%). In another subject splenectomy was performed following a iatrogenic injury (4.7%). Minor complications developed in 5 patients (23.7%). After one year from operation in 1 patient a severe stricture of esophago-jejunal anastomosis appeared; it was treated with anastomotic resection and reconstruction. After 8 years one patient was submitted to a partial resection of interposed jejunal loop, that was redundant. In 18 patients long term follow-up showed good results in 14 patients (78%), discrete in 2 (11%), unsatisfactory in 2 (11%). Our results show that Merendino's esophago-jejunal gastroplasty allows to achieve good results with acceptable rate of mortality and morbidity.

Abstract
Retrospective analysis of the results of esophagojejunogastrostomy in 21 patients with peptic stenosis after esophagomyotomy for achalasia is reported. All patients complained of severe dysphagia. The esophagogram showed the presence of a 2 to 3 cm long stenosis in the lower esophagus with a diameter < 10 mm. Endoscopic dilatation was possible in 18 cases and it was pursued until the passage of the endoscope was possible. Manometry confirmed the presence of an aperistaltic esophagus with incompetent LES in all cases examined. GERD was detected by 24 hour pH-metry in 15/21 patients (71.4%). One patient died because of postoperative cardiopulmonary failure. Other minor complications occurred in 6 patients. During an 11 year mean follow-up good results were achieved in 17 patients (85%), fair in 2 (10%) and poor in 1 (5%), in whom redundant jejunal loop was resected after 8 years. Resective surgery in peptic strictures after esophagomyotomy is the treatment that guarantees the best long-term results. Esophagojejunogastroplasty represents a valid technique. Careful selection of patients and an accurate surgical technique are fundamental to reduce mortality and morbidity.

Abstract
Even if the incidence of esophageal carcinoma is low (25% in comparison to rectal cancer) the total mortality of this disease is very high (superior to rectal cancer itself according to Am.Ca.SO. data). That's because of the high number of non resectable patients when they are first seen by the physician for dysphagia. The aim of the treatment in such cases is to permit a sufficiently good intake to the patient avoiding non-acceptable gastrostomy. The authors report their experience using esophageal prosthesis (27 cases). Mortality rate was 3.7% distal migration 7.4%. They report 3 cases of "minor" complication (11.1%). The mean survival was 5.3 months, the quality of life was satisfactory in all treated cases.

Abstract
The authors present their technique of local anaesthesia in the surgical treatment of phimosis using a cream composed of an eutectic mixture of lidocaine and prilocaine (Emla). This cream, unlike injectable local anaesthetics, allows surgical procedures to be performed on the prepuce without pain.

Abstract
A 9-year-old girl was diagnosed as having a linear sebaceous nevus syndrome (LSNS). The nevus sebaceus was located on the face, and the girl also had nevoid hypertrichosis on the neck, sensorineural deafness, partial anodontia, blocked tear ducts, labiopalatoschisis, and an area of micropolygyria in the left encephalic (cerebral) hemisphere. Electroencephalographic alterations were detected, but they were not accompanied by a history of seizures; furthermore, the child was not mentally retarded. This phenotypic pattern of LSNS is unusual for the rarity of associated abnormalities.
