RESUMO
BACKGROUND: Inverted-bearing reverse shoulder arthroplasty (IB-RSA) is characterized by a polyethylene glenosphere and a metallic humeral liner to minimize PE wear and debris secondary to impingement between the humerus and glenoid neck. IB-RSA long-term survivorship, complication and revision rates, as well as clinical and radiographic outcomes have not been reported yet. METHODS: This is a monocentric retrospective study on a consecutive series of 151 patients who underwent primary IB-RSA from January 2009 to September 2015 and were evaluated clinically and radiologically at minimum 8 years follow-up. All complications and reoperations were recorded. Survivorship analysis with any revision surgery as endpoint was done using Kaplan-Meier survival curves. RESULTS: Seventy-eight patients (follow-up rate 51.7%) were reviewed at a mean follow-up of 10.1 ± 1.9 years. At 10 years the revision-free survival was 98.7% (95% CI: 94.8-99.7). Sixteen complications (10.6%) were observed: 2 axillary nerve injuries, 2 infections, 2 glenoid loosenings (which stabilized within one year), 2 cases of otherwise unexplained painful stiffness, 4 acromial fractures, 1 post-traumatic scapular pillar fracture and 3 post-traumatic humeral periprosthetic fractures. Two patients were revised due to infection. No cases of late glenoid loosening and humeral loosening were observed. The revision rate was 1.3%. All the clinical scores and range of motion significantly improved at the last follow-up compared with preoperative status: final Constant score was 66.1 ± 17.4, SSV 79.1 ± 20.9, ASES 82.2 ± 17.7. Scapular notching was observed in 51.4% of patients: only 1 case of grade 3 notching was observed in an early glenoid subsidence case. CONCLUSIONS: Primary IB-RSA appears to be a safe and effective procedure and does not present specific implant-associated complications at long-term follow-up. Radiographic analysis showed that inverting the biomaterials leads to a distinct kind of notching with mainly mechanical features.
RESUMO
The outbreak of SARS-CoV-2 pandemic highlighted the worldwide lack of surgical masks and personal protective equipment, which represent the main defense available against respiratory diseases as COVID-19. At the time, masks shortage was dramatic in Italy, the first European country seriously hit by the pandemic: aiming to address the emergency and to support the Italian industrial reconversion to the production of surgical masks, a multidisciplinary team of the University of Bologna organized a laboratory to test surgical masks according to European regulations. The group, driven by the expertise of chemical engineers, microbiologists, and occupational physicians, set-up the test lines to perform all the functional tests required. The laboratory started its activity on late March 2020, and as of the end of December of the same year 435 surgical mask prototypes were tested, with only 42 masks compliant to the European standard. From the analysis of the materials used, as well as of the production methods, it was found that a compliant surgical mask is most likely composed of three layers, a central meltblown filtration layer and two external spunbond comfort layers. An increase in the material thickness (grammage), or in the number of layers, does not improve the filtration efficiency, but leads to poor breathability, indicating that filtration depends not only on pure size exclusion, but other mechanisms are taking place (driven by electrostatic charge). The study critically reviewed the European standard procedures, identifying the weak aspects; among the others, the control of aerosol droplet size during the bacterial filtration test results to be crucial, since it can change the classification of a mask when its performance lies near to the limiting values of 95 or 98%.
RESUMO
Epidermolysis bullosa (EB) is a rare inherited genetic disease characterized by an abnormal response of the skin and mucosa to mechanical trauma. Dystrophic EB (DEB) is very often associated with many extra cutaneous complications. Those complications involve either epithelial associated tissues or other organs. In particular, several renal complications have been described for DEB in the recessive form, such as amyloidosis, post-infection glomerulonephritis, upper and lower urinary tract obstruction and IgA-Nephropathy (IgAN). In the cases reported below we have two patients diagnosed with DEB that showed compromised renal function and proteinuria. The switch of the normal diet toward a gluten free diet resulted beneficial for both patients, since renal function was rescued and proteinuria cured. Moreover, a general health status improvement was recognised, given that nutritional condition was ameliorated and bone growing enhanced. Furthermore, in both patients the presence of autoantibodies anti-COL7 indicating an autoimmune form of the disease. Therefore, patients received low doses of betametasone useful to reduce inflammatory state and to control immune system function. In conclusion, our results prompt us to hypothesized that in these patients, due to the fragility of the intestinal mucosa, the absence in the diet of gluten may be beneficial.

BACKGROUND: The aim of this study was to determine the occurrence of gluten sensitivity (GS) in a group of allergic patients and to assess the efficacy of a gluten-free diet (GFD) on the improvement of the symptomatology in those who were diagnosed with GS. METHODS: 262 unrelated allergic patients with gastrointestinal symptoms of obscure origin were tested for GS condition by biopsy. All patients were also genotyped for the typical celiac DQ2 and DQ8 molecules and investigated for several hematological parameters such as antigliadin and antiendomysial antibodies. Patients displaying mucosal lesions were invited to follow a GFD. RESULTS: Seventy-seven of the 262 allergic patients were positive to mucosal lesions, but negative to the antiAGA, antiEMA and to DQ2 and DQ8 molecules. We found, instead, a prevalence of the DQA1*05 allele, whereas anemia of inflammatory origin represented the predominant complaint in our subjects. The positive patients, who, after the GS diagnosis, followed a GFD, exhibited control of symptoms as well as stabilization of the hematological parameters even if allergic manifestations were not abated. CONCLUSIONS: A nonceliac gluten-sensitive enteropathy (NCGSE) commonly occurs in allergic patients. Based on the high prevalence of NCGSE in allergy, it is recommended that biopsy should be part of the routine investigation of allergic disease to offer the benefits of treatment with a GFD to the patients.

Some patients affected by nickel-contact allergy present digestive symptoms in addition to systemic cutaneous manifestations, falling under the condition known as systemic nickel allergy syndrome (SNAS). A nickel-related pro-inflammatory status has been documented at intestinal mucosal level. The aim of the present study is to evaluate the prevalence of lactose intolerance in patients affected by SNAS compared to a healthy population. Consecutive patients affected by SNAS referring to our departments were enrolled. The control population consisted of healthy subjects without gastrointestinal symptoms. All subjects enrolled underwent lactose breath test under standard conditions. One hundred and seventy-eight SNAS patients and 60 healthy controls were enrolled. Positivity of lactose breath test occurred in 74.7% of the SNAS group compared to 6.6% of the control group. Lactose intolerance is highly prevalent in our series of patients affected by SNAS. Based on our preliminary results, we can hypothesize that in SNAS patients, the nickel-induced pro-inflammatory status could temporarily impair the brush border enzymatic functions, resulting in hypolactasia. Further trials evaluating the effect of a nickel-low diet regimen on lactase activity, histological features and immunological pattern are needed.

Some patients with nickel (Ni) allergic contact dermatitis suffer from systemic (intestinal or cutaneous) symptoms after ingestion of Ni-rich foods and experience symptoms reduction with low-Ni diet, a condition termed Systemic Ni Allergy Syndrome (SNAS). We aimed at evaluating whether oral administration of low nickel doses improved clinical conditions and modulated immunological aspects of SNAS, without significant side effects. Thirty-six SNAS patients were enrolled. Treatment started after 1-month of low-Ni diet and consisted in an incremental oral NiOH dose phase (0.3ng to 1.5 microg/week) followed by a 12-months maintenance phase (1.5 microg/week). Randomly, twenty-four patients added Ni therapy to low-Ni diet and 12 remained with diet alone. All patients were allowed rescue medications (antihistamines and topical steroids). After 4 months, Ni-rich foods were gradually reintroduced. In vitro allergen-driven IL13, IL5 and IFN-gamma release by peripheral blood mononuclear cells was evaluated before and after treatment. Twenty-three patients receiving NiOH and the 12 control patients completed the study. Evaluation of SNAS clinical severity (by VAS and drug consumption) showed a significant difference in favor of NiOH-treated patients compared to controls. Twenty of 23 patients in the NiOH group and none in the control group tolerated Ni-rich food reintroduction. Release of all studied cytokines in culture supernatants was significantly lower after NiOH treatment. In conclusion NiOH is effective in reducing symptoms and drug consumption in SNAS and is able to modulate inflammatory parameters.

BACKGROUND: Quality of life (QOL) is an important issue in allergic rhinitis and has been evaluated in a number of studies that have shown how it is impaired in untreated patients and improved by effective treatment. However, there are no data concerning QOL after sublingual immunotherapy (SLIT) in polysensitized patients. OBJECTIVE: To evaluate the effect, in real-life clinical practice, of SLIT on QOL in a population of polysensitized patients with allergic rhinitis. METHODS: We prospectively evaluated 167 consecutively enrolled polysensitized patients with allergic rhinitis. QOL was measured in all cases with the Rhinoconjunctivitis Quality of Life Questionnaire at baseline and after 1 year of SLIT (performed in approximately 70% of cases using single allergen extracts provided by the same manufacturer). RESULTS: The most frequent causes of sensitization were grass pollen, Parietaria, and house dust mites. The mean number of sensitizations per patient was 3.65. SLIT was performed with 1 extract in 123 patients (73.6%), with 2 extracts in 31 patients (18.6%), and with more than 2 extracts in 13 patients (7.8%). The mean values of all the QOL items improved significantly (P < .01 in all cases), with the following reductions noted: activities, 3.96 to 2.89; sleep, 2.07 to 1.56; general problems, 2.16 to 1.5; practical problems, 3.69 to 2.58; nasal symptoms, 3.57 to 2.50; eye symptoms, 2.92 to 1.83; and emotional aspects, 2.2 to 1.44. CONCLUSIONS: This study provides evidence that QOL can be improved in polysensitized patients treated with SLIT, and that the use of just 1 or 2 allergen extracts seems to be sufficient and effective in terms of improving QOL.

Polysensitization is very common in allergic patients and was previously reported to be associated with more severe symptoms and impaired quality of life. Polysensitization is often considered as a contraindication for specific immunotherapy (SIT). This study is aimed at evaluating the allergist attitude for decision making in choosing SIT in a cohort of Italian polysensitized patients. Moreover, the 1-year effectiveness of the prescribed sublingual immunotherapy (SLIT) in this cohort was evaluated. The study was performed on 244 patients (109 males, 135 females, mean age 28.7 years, S.D. 12.0) with allergic rhinitis (assessed by ARIA criteria) and/or mild to moderate asthma (assessed by GINA criteria) treated with SLIT for 1 year. The kind and the number of prescribed allergen extracts, type of diagnosis, severity of symptoms, use of drugs, and adverse events were evaluated at baseline and after 1 year. A total of 230 patients were treated with SLIT: 165 with a single extract, and 65 with two different extracts (mix). SLIT treatment significantly improved disease staging, and reduced symptom severity and drug use. No systemic reaction was reported. In conclusion, these findings provide preliminary evidence that SIT is effective and safe in polysensitized patients after 1 year of treatment also using single extracts, and thus does not represent an obstacle for prescribing SIT.

BACKGROUND: The natural history of respiratory allergy is commonly characterized by a worsening of symptom severity, frequent comorbidity of rhinitis and asthma, and polysensitization to aeroallergens. The polysensitization phenomenon starts since childhood and is rare to find monosensitized adult patients. However, there are few studies investigating the characteristics of polysensitized patients. METHODS: This study was performed on a large cohort of patients with allergic rhinitis (assessed by ARIA criteria) and/or mild to moderate asthma (assessed by GINA). The kind and the number of sensitizations, their patterns, and the relation with quality of life (QoL) measured by the Juniper's RQLQ guestionnaire, were evaluated. RESULTS: Globally 418 patients (50.2% males, 49.8% females, mean age 26.4 years, range 3.5-65 years, 64 smokers, 371 non-smokers) were enrolled: 220 had allergic rhinitis alone, and 198 allergic rhinitis and asthma. The mean number ofsensitizations was 2.6. Three hundred-five patients (73%) had persistent rhinitis (PER), 220 of them with moderate-severe form. There was no significant derence in rate of rhinitis and asthma in monosensitized or polysensitized patients. Most patients were sensitized to pollens, whereas only 24.2% of them were sensitized to perennial allergens. Polysensitization was significantly associated with some issues of QoL, confirming previous findings, but not with number ofsensitizations. CONCLUSIONS: This study provides data confirming for poly-sensitized patients the relevance of ARIA classification of AR. PER is the most common form of AR in this cohort, symptoms are frequently moderate-severe, and asthma is present in about the half of patients with AR.

BACKGROUND: The presence of persistent mild inflammation is widely considered to provide the immunopathogenic basis for bronchial, nasal, or sinusal inflammation between critical phases and in asymptomatic periods. Exhaled nitric oxide (NO) is currently the most reliable marker of rhinobronchial inflammation, but its routine assessment is difficult as the test is available only in highly specialized centers. OBJECTIVE: The aim of this study was to evaluate the agreement between a new diagnostic method (extracellular electrical impedance tomography) and immunological and clinical symptom scores, anterior rhinomanometry, peak expiratory flow rate (PEFR), serum eosinophil cationic protein (ECP) level, and blood eosinophil count in the clinical monitoring of respiratory tract inflammation before and after treatment of asthma or rhinitis. PATIENTS AND METHODS: Eighty-seven patients were studied; 73 had mild persistent asthma (PEFR > or = 20% below predicted) and 14 had rhinitis. At baseline (TO), the patients underwent a medical examination to record symptom scores, PEFR, anterior rhinomanometry, an extracellular electrolytic conductivity test (bioimpedance tomography), serum ECP level and blood eosinophil count. Appropriate treatment was prescribed, following the guidelines of the Global Initiative for Asthma and the Allergic Rhinitis and Its Impact on Asthma. After 21 days of therapy (T1), the patients were re-evaluated for the same parameters. RESULTS AND CONCLUSIONS: This study demonstrates the good agreement (Cohen's kappa = 0.689) between the symptom scores of patients with rhinitis and the findings of extracellular tomography and very good agreement (kappa = 0.846) between symptom scores of asthma patients and extracellular tomography. These findings validate the use of this new technique for the real-time monitoring and adjustment of treatment in these clinical settings.

The current burden of allergic diseases, estimated by both direct and indirect costs, is very relevant. In fact the cost estimation for rhinitis amount globally to 4-10 billion dollars/year in the U.S. and to an average annual cost of 1089 euros per child/adolescent and 1543 euros per adult in Europe. The estimated annual costs in Northern America for asthma amounted to 14 billion dollars. Consequently, preventive strategies aimed at reducing the clinical severity of allergy are potentially able to reduce its costs. Among them, specific immunotherapy (SIT) joins to the preventive capacity the carryover effect once treatment is discontinued. A number of studies, mainly conducted in the US and Germany demonstrated a favourable cost-benefit balance. In the nineties, most surveys on patients with allergic rhinitis and asthma reported significant reductions of the direct and indirect costs in subjects treated with SIT compared to those treated with symptomatic drugs. This is fully confirmed in recent studies conducted in European countries: in Denmark the direct cost per patient/year of the standard care was more than halved following SIT; in Italy a study on Parietaria allergic patients demonstrated a significant difference in favor of SIT plus drug treatment for three years versus drug treatment alone, with a cost reduction starting from the 2nd year and increasing to 48% at the 3rd year, with a highly statistical significance which was maintained up to the 6th year, i.e. 3 years after stopping immunotherapy, corresponding to a net saving for each patient at the final evaluation of 623 euros per year; in France a cost/efficacy analysis comparing SIT and current symptomatic treatment in adults and children with dust mite and pollen allergy showed remarkable savings with SIT for both allergies in adults and children.

Allergic rhinitis and asthma constitute a global health problem because of their very high prevalence and the consequent burden of disease, concerning medical and economical issues. Among the treatments of allergy, specific immunotherapy has the capacity to favourably alter the natural history of the disease both during and after its performance and thus to reduce the direct and indirect costs of allergic rhinitis and asthma. A number of studies reported such cost reduction for traditional, subcutaneous immunotherapy and recent data demonstrate that also sublingual immunotherapy (SLIT) is associated to economic advantages and/or monetary savings, specifically in terms of reduction of disease economic burden. Only few formal economic assessments of SLIT have been carried out so far, this article will present and discuss the published studies addressed to this issue. The data obtained, although the number of studies is still limited, provide preliminary evidence supporting a SLIT effect on sparing costs for respiratory allergy.

The efficacy and safety of sublingual immunotherapy (SLIT) are currently supported by clinical trials, meta-analysis and post-marketing surveys. Practice parameters for clinical use of SLIT are proposed here by a panel of Italian specialists, with reference to evidence based criteria. Indications to SLIT include allergic rhinoconjunctivitis, asthma, and isolated conjunctivitis (strength of recommendation: grade A). As to severity of the disease, SLIT is indicated in moderate/severe intermittent rhinitis, persistent rhinitis and mild to moderate asthma (grade D). SLIT may be safely prescribed also in children aged three to five years (grade B), and its use in subjects aged more than 60 years is not prevented when the indications and contraindication are ascertained (grade D). The choice of the allergen to be employed for SLIT should be made in accordance with the combination of clinical history and results of skin prick tests (grade D). Polysensitisation, i.e. the occurrence of multiple positive response does not exclude SLIT, which may be done with the clinically most important allergens (grade D). As to practical administration, co-seasonal, pre co-seasonal, and continuous schedules are available, being the latter recommended for perennial allergens or for pollens with particularly prolonged pollination, such as Parietaria (grade D). For pollens with relatively short pollination, such as grasses and trees (cypress, birch, alder, hazelnut, olive) the pre co-seasonal and perennial schedules are preferred (grade C). The build-up phases suggested by manufacturers can be safely used (grade A), but they can be modified according to the patient's tolerance (grade C). A duration of SLIT of 3-5 years is recommended to ensure a long-lasting clinical effect after the treatment has been terminated (grade C).

The B72.3 reactive antigen, TAG-72, has been purified and a series of second generation monoclonal antibodies (MAbs), designated CC (colon cancer), have been characterized by a range of in vitro immunological assays. Six CC MAbs (CC11, CC30, CC46, CC49, CC83, and CC92) were chosen for analyses of the in vivo binding to a human colon carcinoma xenograft. All 6 MAbs were previously shown to be distinct from B72.3 and each other by a series of reciprocal competition radio-immunoassays, and all were shown to have a Ka higher than that of B72.3. In this study we demonstrate that all six CC MAbs evaluated are superior to B72.3 in an in vivo tumor targeting model, using human colon carcinoma (LS-174T) xenografts in athymic mice, in terms of both the percentage of the injected dose of radiolabeled MAb delivered per g of tumor and tumor:normal tissue ratios. Differences in the in vivo binding patterns and pharmacokinetics among the CC MAbs are also evaluated. Thus, in light of the fact that B72.3 has been shown to successfully target approximately 75% of primary and metastatic carcinoma lesions in a variety of different carcinoma types in over 300 patients, these studies serve as further evidence to support the clinical evaluation of the second generation CC MAbs, either alone or in combination with B72.3.

Adjuvant trastuzumab (AT) dramatically improved HER2-positive breast cancer prognosis. Relapsed disease after AT has different patterns and information is available from observational studies. In this Review Chemotherapy regimens combined to anti-HER2 blockade are discussed, focusing in particular the role of anthracyclines, taxanes and capecitabine. The use of trastuzumab beyond progression and the role of other anti-HER2 agents like lapatinib, pertuzumab and T-DM1 are explored, as also dual blockade and in trastuzumab resistant Patients. Metastatic "de novo" HER2 Luminal (co-expression of HER2 and hormone receptors) Patients are eligible for anastrozole and trastuzumab but if pretreated with trastuzumab they are also eligible for lapatinib and letrozole. In any case endocrine treatment plays a complementary role to chemotherapy which remains pivotal. The last topic explored is treatment options for patients with brain metastases where both trastuzumab given concurrent with radiotherapy or lapatinib and capecitabine appear as potentially active.

The efficacy and safety of long-term treatment with oral nitrendipine were evaluated in 34 patients with essential arterial hypertension. Nitrendipine alone significantly lowered systolic and diastolic blood pressure levels in 28 patients who completed the preliminary four-week dose-setting phase. Twenty-one patients completed the one-year treatment. Blood pressure control was maintained by nitrendipine alone in 11 patients. Ten patients not adequately controlled at the end of the dose-setting phase were successfully treated with nitrendipine combined with acebutolol or muzolimine. It is concluded that nitrendipine is a promising calcium antagonist for the treatment of arterial hypertension.

Epidemiological studies on the pollens responsible for allergic diseases throughout Italy are lacking. Routine diagnostic panels consist prevalently of grass, Parietaria, weeds, birch, olive and mugwort. Considering the great variety of Italian geographical areas and the observation of the growing allergological importance of new botanical species (e.g., ambrosia), a survey on pollen species considered "minor" was necessary. A panel of "emerging" pollens (birch, hazelnut, alder, hornbeam, cypress, ragweed) and a routine panel were used to skin prick test 2,934 consecutive outpatients with respiratory pathology of suspected allergic origin, in 21 centers across Italy. A specific questionnaire was compiled. It was found that 20.1% of patients did not react to allergens tested, 28.2% were positive for at least one emerging pollen and 51.7% did not react to emerging pollens but tested positive for at least one allergen from the routine panel. The prevalence of single pollen species was related to geographical areas. Ragweed pollen was shown to provoke asthma much more frequently than other pollens. Hitherto scarcely considered pollens play a considerable role in causing allergic diseases in Italy. In the great majority of patients, positivity for these pollens was associated with positivity to the better recognized group of pollen allergens, although in some cases they were the primary pathogenic agent. We suggest that these more recently considered allergens be included in routine diagnostic panels.

AIMS AND BACKGROUND: Doxifluridine (RO 21-9738, 5'-dFUR) is a fluoropyrimidine derivative with proven antitumor activity in different experimental models. On the basis of experimental evidence, several clinical trials have been carried out to define the optimal 5'-dFUR dose and route of administration. In general, the maximum monthly dose of 5'-dFUR was 36-38 g. According to these clinical data, we explored the feasibility of a combination of 5'-dFUR and interferon-alpha-2a (IFN-alpha-2a). The aim of the protocol was to confirm the maximum tolerated dose (MTD) of the drug in combination with a settled dose of IFN alpha 2a. METHODS: An open-label phase I study with intravenous 5'-dFUR was carried out in 12 patients with a histologically proven diagnosis of advanced gastrointestinal or breast cancer refractory to previous conventional hormone-chemotherapy. Escalating doses of 5'-dFUR were administered as a 2-h intravenous infusion, once a week for at least 4 weeks in groups of 3 patients. IFN-alpha-2a was administered as an intramuscular injection of 3 MU 3 times a week for 4 consecutive weeks. Physical and laboratory parameters were assessed at baseline and then weekly until the end of treatment. RESULTS: The treatment with 5'-dFUR was stopped at 5 g/m2, since this level corresponded to the maximum monthly dosage reported in the literature (36-38 g). No severe toxicity was recorded up to this drug level. CONCLUSIONS: The combination of 5'-dFUR plus IFN-alpha-2a was well tolerated at the level of 5 g/m2.

Primary non-Hodgkin's lymphomas (NHL) of the breast represent less than 3% of extranodal NHL; in comparison to extranodal NHL at other sites, they are characterized by rapid progression and worse prognosis. We report a case of primary NHL of the breast treated, after surgery, with a sequential combination of chemotherapy and radiotherapy. Literature data suggest that the most important factors in therapeutic decisions making are the initial stage of the disease and the histological subtype.

We report a case of primary squamous cell carcinoma of the breast in a 58 years old woman. The diagnosis of this rare tumor is possible after excluding a skin primary lesion or an epidermoid cancer of a distant site. In reviewing the reported cases we didn't find any significant prognostic difference between this form and the breast adenocarcinoma with squamous metaplasia.
