Reggio Emilia (Northern Italy) Interdisciplinary Uveitis Clinic: What We Have Learned in the Last 20 Years.

PURPOSE: To analyze the referral patterns and the clinical and therapeutic features of patients diagnosed with uveitis in an Italian tertiary referral center to provide a comparison with previously published series from the same center. METHODS: Retrospective retrieval of data on all new referrals to the Ocular Immunology Unit in Reggio Emilia (Italy) between November 2015 and April 2022 and comparison with previously published series from the same center. RESULTS: Among the 1557 patients, the male-to-female ratio was 1:1.27. Anterior uveitis was the most common diagnosis (53.7%), followed by posterior (21.6%), pan- (18.5%), and intermediate (6.2%) uveitis. The most identifiable specific diagnoses were anterior herpetic uveitis (18.4%), Fuchs uveitis (12.8%), and tuberculosis (6.1%). Infectious etiologies were the most frequent (34.1%) and were more diffuse among non-Caucasian patients (p < 0.001), followed by systemic disease-associated uveitis (26.5%), and ocular-specific conditions (20%). Idiopathic uveitis accounted for 19.4% of cases. Fuchs uveitis presented the longest median diagnostic delay (21 months). Immunosuppressants were administered to 25.2% of patients. Antimetabolites, calcineurin inhibitors, and biologicals were prescribed to 18.4%, 3%, and 11.4% of cases, respectively. Compared to our previous reports, we observed a significant increase in foreign-born patients and in infectious uveitis, a decrease in idiopathic conditions, and an increasing use of non-biological and biological steroid-sparing drugs. CONCLUSIONS: The patterns of uveitis in Italy have been changing over the last 20 years, very likely due to migration flows. Diagnostic improvements and a more widespread interdisciplinary approach could reduce the incidence of idiopathic uveitis as well as diagnostic delay.

EACVI survey on radiation exposure in interventional echocardiography.

AIMS: The European Association of Cardiovascular Imaging (EACVI) Scientific Initiatives Committee performed a global survey on radiation exposure in interventional echocardiography. The survey aimed to collect data on local practices for radioprotection in interventional echocardiography and to assess the awareness of echocardiography operators about radiation-related risks. METHODS AND RESULTS: A total of 258 interventional echocardiographers from 52 different countries (48% European) responded to the survey. One hundred twenty-two (47%) participants were women. Two-thirds (76%) of interventional echocardiographers worked in tertiary care/university hospitals. Interventional echocardiography was the main clinical activity for 34% of the survey participants. The median time spent in the cath-lab for the echocardiographic monitoring of structural heart procedures was 10 (5-20) hours/month. Despite this, only 28% of interventional echocardiographers received periodic training and certification in radioprotection and 72% of them did not know their annual radiation dose. The main adopted personal protection devices were lead aprons and thyroid collars (95% and 92% of use, respectively). Dedicated architectural protective shielding was not available for 33% of interventional echocardiographers. Nearly two-thirds of responders thought that the radiation exposure of interventional echocardiographers was higher than that of interventional cardiologists and 72% claimed for an improvement in the radioprotection measures. CONCLUSION: Radioprotection measures for interventional echocardiographers are widely variable across centres. Radioprotection devices are often underused by interventional echocardiographers, portending an increased radiation-related risk. International scientific societies working in the field should collaborate to endorse radioprotection training, promote reliable radiation dose assessment, and support the adoption of radioprotection shielding dedicated to interventional echocardiographers.

Simultaneous speciation analysis of Hg and Se in fish by high-performance liquid chromatography and inductively coupled plasma-mass spectrometry following microwave-assisted enzymatic hydrolysis.

This study reports the development and validation of a new analytical method for simultaneous speciation analysis of Se and Hg in fish muscle. For this purpose, four Se species (selenite/Se(IV), selenate/Se(VI), selenomethionine/SeMet, and selenocysteine/SeCys) and two Hg species (inorganic mercury/iHg and methylmercury/MeHg) were extracted simultaneously by microwave-assisted enzymatic hydrolysis and then separated by HPLC in less than 15 min by using a column with both anion and cation exchange mechanisms and a mobile phase consisting of a mixture of methanol 5% (v/v), 45 mM HNO3, 0.015% 2-mercaptoethanol, and 1.5 mM sodium 3-mercapto-1-propanesulfonate. The separated species of Hg and Se were detected online by inductively coupled plasma-mass spectrometry (ICP-MS). The speciation analysis method was validated by means of the accuracy profile approach by carrying out three series of measurements in duplicate on three different days over a time-span of 3 weeks. The limits of quantification (LOQ) are in the range of 0.010-0.013 mg/kg wet weight (ww) for all selenium species, except for Se(IV) (0.15 mg/kg ww), while the coefficient of variation in terms of intermediate reproducibility (CVR) was < 7%. The LOQ for MeHg was 0.006 mg/kg ww, while the CVR was 3%. The method was successfully applied to the analysis of muscle samples from four different fish species: rainbow trout, tuna, swordfish, and dogfish.

Prognostic utility of the assessment of diastolic function in patients undergoing cardiac resynchronization therapy.

Conflicting data exist about the relationship between cardiac resynchronization therapy (CRT) and diastolic function. Aims of the study are to assess diastolic patterns in patients undergoing CRT according to the 2016 recommendations of the American Society of Echocardiography/European Association of Cardiovascular Imaging and to evaluate the prognostic value of diastolic dysfunction (DD) in CRT candidates. METHODS AND RESULTS: One-hundred ninety-three patients (age: 67 ± 11 years, QRS width: 167 ± 21 ms) were included in this multicentre prospective study. Mitral filling pattern, mitral tissue Doppler velocity, tricuspid regurgitation velocity, and indexed left atrial volume were used to classify DD from grade I to III. CRT-response, defined as a reduction of left ventricular (LV) end-systolic volume > 15% at 6-month follow-up (FU), occurred in 132 (68%) patients. The primary endpoint was a composite of heart transplantation, LV assisted device implantation, or all-cause death during FU and occurred in 29 (15%) patients. CRT was associated with a degradation of DD in non-responders. At multivariable analysis corrected for clinical variables, QRS duration, mitral regurgitation, CRT-response and LV dyssynchrony, grade I DD was associated with a better outcome (HR 0.37, 95% CI: 0.14-0.96). Non-responders with grade II-III DD had the worse prognosis (HR 4.36, 95%CI: 2.10-9.06). CONCLUSIONS: The evaluation of DD in CRT candidates allows the prognostic stratification of patients, independently from CRT-response.

Environmental risk assessment of the anionic surfactant sodium lauryl ether sulphate in site-specific conditions arising from mechanized tunnelling.

Sodium lauryl ether sulphate (SLES) is the anionic surfactant commonly utilized as the main synthetic chemical component in most foaming agents used in mechanized tunnelling. This produces huge amounts of soil debris which can contain residual concentrations of SLES. The absence of environmental quality standards for soil and water and the limited information about SLES persistence in real excavated soils do not facilitate any re-use of soil debris as by-products. The environmental risk assessment (ERA) of foaming agents containing SLES can be a valid tool for this purpose. In this study, an ERA analysis of SLES in 12 commercial formulations (cf) used for tunnelling excavation was performed. Various soils from different tunnel excavation sites were conditioned with the selected foaming agents containing SLES. Predicted or measured environmental concentrations (PECs, MECs) were determined and then compared with the Predicted No Effect Concentrations (PNECs) for both the terrestrial and aquatic compartments. The results indicate a reduction of the potential risk over time for these ecosystems, with differences depending on both the commercial foaming formulation and the spoil material characteristics. However, because potential threats to the natural environment cannot be excluded, some risk management and mitigation actions are discussed.

Atopic Dermatitis Phenotypes in Preschool and School-Age Children: A Latent Class Analysis.

BACKGROUND: Atopic dermatitis (AD) is the most common chronic inflammatory skin disease in childhood. Few data are available about AD phenotypes and their nationwide distribution. METHODS: We performed a cross-sectional multicenter study involving some of the main Italian pediatric allergy centers from 9 Italian cities. A structured questionnaire was administered to 371 children with AD. Patients were divided in 2 groups: preschool children (aged ≤5 years) and schoolchildren (aged 6-14 years). A latent class analysis was used to detect AD phenotypes and to investigate their association with risk factors and other atopic diseases. RESULTS: Latent class analysis identified 5 AD phenotypes in preschoolers ("moderate-severe AD, high comorbidity", 8%; "moderatesevere AD, low comorbidity", 35%; "mild AD, low comorbidity", 20%; "mild AD, respiratory comorbidity", 32%; "mild AD, food-induced comorbidity", 5%) and 4 AD phenotypes in schoolchildren ("moderate-severe AD, high comorbidity", 24%; "moderate-severe AD, low comorbidity", 10%; "mild AD, low comorbidity", 16%; "mild AD, respiratory comorbidity", 49%). Parental history of asthma and eczema, early day-care attendance, and exposure to molds were significantly associated with the "moderate-severe AD, high comorbidity" phenotype in preschool children (P<.05). The "moderate-severe AD" phenotypes were also associated with the highest burden in terms of medication use and limitations in daily activities. CONCLUSIONS: The detection of different AD phenotypes highlights the need for a stratified approach to the management of this complex disease and for further studies to predict the course of AD and to develop more efficient therapeutic strategies.

Avalanches and criticality in self-organized nanoscale networks.

Current efforts to achieve neuromorphic computation are focused on highly organized architectures, such as integrated circuits and regular arrays of memristors, which lack the complex interconnectivity of the brain and so are unable to exhibit brain-like dynamics. New architectures are required, both to emulate the complexity of the brain and to achieve critical dynamics and consequent maximal computational performance. We show here that electrical signals from self-organized networks of nanoparticles exhibit brain-like spatiotemporal correlations and criticality when fabricated at a percolating phase transition. Specifically, the sizes and durations of avalanches of switching events are power law distributed, and the power law exponents satisfy rigorous criteria for criticality. These signals are therefore qualitatively and quantitatively similar to those measured in the cortex. Our self-organized networks provide a low-cost platform for computational approaches that rely on spatiotemporal correlations, such as reservoir computing, and are an important step toward creating neuromorphic device architectures.

Current therapeutic paradigm in pediatric atopic dermatitis: Practical guidance from a national expert panel.

INTRODUCTION AND OBJECTIVES: Atopic dermatitis (AD) is the most common cutaneous inflammatory disease in both adults and children. Although emerging therapeutic approaches are being investigated for the management of pediatric AD, it still needs to be managed with conventional treatments. This consensus document is aimed at providing an update on general management and therapies of pediatric AD, defining practical recommendations for using both topical and systemic agents. MATERIAL AND METHODS: A panel of experts consisting of dermatologists and pediatricians were convened in order to define statements, through a Delphi process, standardizing the management of AD in pediatric subjects in a real-world setting. RESULTS: A set of practical recommendations obtaining an at least 75% agreement was presented. CONCLUSIONS: This set of practical recommendations represents a simple and fast snapshot on the pediatric use of common anti-AD therapeutics.

Cirugía ortognática para el tratamiento de las anomalías dentoesqueletales / Orthognathic surgery for the treatment of dentoskeletal abnormalities

Las anomalías dentoesqueletales se presentan en el 2-3% de la población. Las mismas afectan el complejo maxilomandibular como también la relación entre las arcadas dentarias. Estas alteraciones producen problemas fonéticos, deglutorios, respiratorios y estéticos. Existe una tendencia en corregir las alteraciones dentarias sin tratar las discrepancias esqueletales, dificultando la corrección quirúrgica, si esta fuera necesaria. Actualmente, la cirugía ortognática ha tenido mayor aceptación como el tratamiento ideal para pacientes con estas anomalías. Se presentará una revisión de la literatura sobre las características que esta alteración presenta, junto a la resolución de casos clínicos (AU)

Long-term treatment with low-dose medicine in chronic childhood eczema: a double-blind two-stage randomized control trial.

BACKGROUND: The efficacy of low-dose medicine (LDM) in childhood mild/moderate eczema is not known. We conducted a double-blind, two-stage, randomized, placebo-controlled clinical trial, lasting 23 months, to address this issue. METHOD: Eighty children with chronic mild/moderate eczema were randomly allocated to Group A (placebo) or Group B (treatment group; Galium-Heel®, a low-dose multicomponent medicine based upon natural substances; Guna-Interleukin 12 and Guna-Interferon-γ administered twice a day for six non-consecutive months for each stage). LDM is characterized by the use of biological molecules, such as cytokines, neuropeptides, growth factors, hormones at very low concentrations, which correspond to physiological levels within the human body. The dosage of the cytokines used in this trial (IFN-γ and IL-12) is 10 fg/ml. The SCORAD index was evaluated by the same operator: subjects with a SCORAD index below 20 were considered to have mild eczema (61/80; mean: 10.79), whereas a SCORAD index between 20-50 indicated moderate eczema (19/80; mean: 26.84). The data of 66/80 children were analyzed in stage 1 and those of 62/66 children in stage 2. The primary outcome measure was reduction of eczema severity assessed by the SCORAD index. Secondary outcomes were disease-free interval, and treatment safety and tolerability. RESULTS: The decrease in disease severity was greater in Group B than in Group A already in stage 1 (a decrease 63.9% versus 53.2%), but the difference was not significant (p = 0.16). Moreover, subjective symptoms (itching and sleep disturbances) initially decreased and then worsened in Group A, whereas itching decreased linearly and sleep disturbances decreased significantly (p=0.049) in Group B. CONCLUSIONS: Preliminary evidence suggests potential benefit, but further work is needed to validate this approach. TRIAL REGISTRATION: The trial was registered with EudraCT number 2010-018640-13 through the database of the National Clinical Trials Monitoring Centre Database (Osservatorio delle Sperimentazioni Cliniche, OsSC) of the Italian Medicines Agency.

P697New indices for a best quantification of left ventricular function in heart valve diseases.

Aims.The Assessment of left ventricular (LV) function remains a clinical challenge especially in patients with preserved LV ejection fraction (EF) and valvular heart diseases (VHD). Mechanical dispersion is supposed to be a strong predictor of events and, to be related to the extent of fibrosis. Regional cardiac work is a new validated and very promising approach to quantify LV-function.We investigated the differences in mechanical dispersions and global LV work (totW) and wasted work fraction (WWF) in normal subjects and in patients with severe primary mitral regurgitation (MR) and severe aortic stenosis (AS). METHODS AND RESULTS: A complete transthoracic echocardiography was performed in 21 normal subject, 97 patients with severe valvulopathy (47 AS, 50 MR) and preserved LV EF. Segmental strain analysis was performed in all patients and the dispersion of regional LV strain curves was computed automatically considering peaks and integrals. The LV-pressure was estimated non-invasively using a standard waveform fitted to valvular events and scaled to systolic blood pressure. Using pressure-strain loops, regional cardiac work indices were computed.LVEF was 66±12 in controls, 65±9 in MR and 65±4% in AS (p=0.125). Global longitudinal strain was -23±2.7 in controls, -24±2.9 in MR and -18±3.2% in AS (p < 0.001). The mechanical dispersion was 38±7.9 in controls, 36±11 in MR, and much higher in the hypertrophied LV of the AS: 60±19ms (p < 0.001). Cardiac work was 2200±260 in controls, 2100±270 in MR, and much lower in AS: 1700±280 mmHg.% (p < 0.001). The wasted work fraction (WWF) was even more describing how different the LV systolic function is in the 3 groups (figure1). CONCLUSION: Longitudinal strain data are robusted and new indices might be calculated based on them. These seem especially promising for a more pathophysiological driven analyzing of LV-functions.

Prognostic value of left atrial reservoir function in patients with severe aortic stenosis: a 2D speckle-tracking echocardiographic study.

AIMS: The aim of this article is to assess the left atrial (LA) reservoir function in patients with severe aortic stenosis (AS) and to evaluate its impact on the recurrence of major adverse cardiac events (MACEs). METHODS AND RESULTS: About 128 patients (mean age 79 ± 9 years) with severe AS were included in the study. Global peak LA strain (PLAS) measured by two-dimensional speckle-tracking echocardiography (STE) during left ventricular (LV) systole represented the LA reservoir function. Overall death, hospitalization for cardiac cause, and worsening heart failure were defined as MACEs. With respect to the values observed in a control group of 20 healthy patients, PLAS resulted significantly reduced in AS. According to the multivariate linear regression analysis, LV global longitudinal strain, mitral E/e' ratio, and systolic pulmonary arterial pressure (sPAP) were the best correlates to PLAS. During follow-up, the predefined MACEs occurred in 39 patients. According to the multivariate Cox regression analysis, a PLAS <21% was a significant predictor of MACEs [hazard ratio (HR) 2.88, P = 0.04], as was coronary artery disease (HR 2.68, P = 0.004) and the New York Heart Association functional class (HR 2.08, P = 0.03). CONCLUSION: In patients with severe AS, a global PLAS <21% is an independent predictor of prognosis. Given the combined influence of LV diastolic and systolic function and of LA performance on sPAP, the decline of PLAS might be considered a marker of global myocardial impairment in AS. Further studies are needed to confirm the critical role of LA relaxation in prognosis and to validate its relevance in routine clinical practice.

Serum Vitamin D levels and Vitamin D supplementation do not correlate with the severity of chronic eczema in children.

BACKGROUND: Eczema is one of the most common chronic inflammatory skin diseases, affecting about 20% of children. The pathogenic mechanisms of eczema are still not fully understood, and current treatment of moderate-severe eczema is often difficult. Recently, it has been suggested that Vitamin D plays a key role in this disease, even if mechanisms are only partially known. OBJECTIVE: The purpose of our study was to assess the 25-Hydroxyvitamin D serum levels in a pediatric population suffering from chronic eczema (IgE-mediated and non-IgE-mediated), and to correlate these phenotypes with the SCORAD severity and selected clinical and biological parameters. Moreover, we aimed to evaluate whether a supplementation of Vitamin D3 could affect the same clinical and laboratory parameters. METHODS: 89 children with chronic eczema were enrolled in the study. Severity of eczema was assessed with the SCORAD index. Past and present history was taken, and patients were divided into two groups according to the state of sensitization. According to a randomization schedule, the enrolled children were assigned to the following groups: supplementation group, which received a daily oral Vitamin D3 supplementation (2000 IUs) for 3 months; control group which received no supplementation. RESULTS: Vitamin D concentrations in patients with moderate and severe eczema were not statistically different from Vitamin D concentration detected in the serum of patients with mild eczema. Furthermore, we did not find any correlation between Vitamin D levels, total IgEs and SCORAD index, both in the Sensitized and in the Not-Sensitized group. The Vitamin D3 supplementation did not influence the SCORAD severity or the total IgEs concentration. CONCLUSION: To our knowledge, our study is the first one that shows no correlation between serum levels of Vitamin D, eczema severity and IgE sensitization in a pediatric population suffering from chronic eczema.

Role of two sequence motifs of mesencephalic astrocyte-derived neurotrophic factor in its survival-promoting activity.

Mesencephalic astrocyte-derived neurotrophic factor (MANF) is a prosurvival protein that protects the cells when applied intracellularly in vitro or extracellularly in vivo. Its protective mechanisms are poorly known. Here we studied the role of two short sequence motifs within the carboxy-(C) terminal domain of MANF in its neuroprotective activity: the CKGC sequence (a CXXC motif) that could be involved in redox reactions, and the C-terminal RTDL sequence, an endoplasmic reticulum (ER) retention signal. We mutated these motifs and analyzed the antiapoptotic effect and intracellular localization of these mutants of MANF when overexpressed in cultured sympathetic or sensory neurons. As an in vivo model for studying the effect of these mutants after their extracellular application, we used the rat model of cerebral ischemia. Even though we found no evidence for oxidoreductase activity of MANF, the mutation of CXXC motif completely abolished its protective effect, showing that this motif is crucial for both MANF's intracellular and extracellular activity. The RTDL motif was not needed for the neuroprotective activity of MANF after its extracellular application in the stroke model in vivo. However, in vitro the deletion of RTDL motif inactivated MANF in the sympathetic neurons where the mutant protein localized to Golgi, but not in the sensory neurons where the mutant localized to the ER, showing that intracellular MANF protects these peripheral neurons in vitro only when localized to the ER.

C4 -consumers in southern Europe: the case of Friuli V.G. (NE-Italy) during early and central Middle Ages.

Isotope variations were studied in necropolises of the early (6th to 7th century CE) and central (10th to 11th century CE) medieval period located in Fruili-Venezia Giulia (Northeastern Italy). The two periods each shortly followed two great barbarian invasions that changed the politics and economy of Italy: the arrivals of Langobards in 578 CE and the Hungarian incursions from the end of the 9th to the first half of the 10th century. These events had a tragic effect on the economy of Friuli-Venezia Giulia: severe depopulation and the partial abandonment of the countryside with fall of agricultural production.

Association of KIF3A, but not OVOL1 and ACTL9, with atopic eczema in Italian patients.

BACKGROUND: Atopic eczema (AE) (OMIM %603165) is the most common chronic inflammatory skin disease characterized by xerosis, pruritus, and erythematous lesions with increased transepidermal water loss. It's a complex disease due to the interaction between environmental and genetics factors. To date, different loci have been related to the disease. OBJECTIVES: To verify the association, between AE and rs479844, rs2164983, and rs2897442, target for OVOLI (11q13), ACTL9 (19p13.2), and in KIF3A (5q31) genes in the Italian population. Recently, these SNPs have been validated as associated to the disease. METHODS: A case-control study testing a cohort of 359 AE cases and 778 controls. RESULTS: We confirmed the association between rs2897442 in KIF3A gene and the disease at both allele and genotype level (P-value: 4.8 × 10(-4) and P-value: 6.3 × 10(-4), respectively). The C allele of the SNP showed an Odds Ratio (OR) of 1.46 (95% CI 1.18-1.82), moreover the CC genotype achieved an OR of 2.77 (95% CI 1.66-4.61). We failed to reveal association between AE and the other two SNPs tested. CONCLUSIONS: Our study indicated KIF3A as a novel gene implicated in the development of AE in the Italian population.

Hemophilic chronic synovitis: therapy of hemarthrosis using endovascular embolization of knee and elbow arteries.

PURPOSE: Congenital hemophilia is a hereditary bleeding disorder that affects 1 in 5,000 males and is characterized by repetitive musculoskeletal bleeding episodes. Selective embolization of the knee and elbow arteries can prevent bleeding episodes. To evaluate the long-term efficacy of these procedures, we assessed the outcomes of 30 procedures performed in our center. METHODS: We performed 30 procedures in 27 hemophilic patients, including 23 knee, and 7 elbow procedures. To evaluate the efficacy of selective embolization of knee and elbow arteries in people with hemophilia, we analyzed the number of bleeding episodes during 12 months before the procedure compared with the amount of episodes that occurred 3, 6, and 12 months after embolization. RESULTS: Twenty-nine of 30 procedures were classified as successful. The median of 1.25 episodes per month (range 0-3) observed before the procedure was reduced to 0 (range 0-1.67; p < 0.001) at 3 months, 0.17 (range 0-1.67; p < 0.001) at 6 months, and 0.33 (range 0-1.67; p = 0.024) at 12 months. Three patients remained free of bleeding events for more than 6 months. Additionally, after the procedure there was a significant reduction in factor FVIII usage that sustained up to 12 months after the procedures. No serious adverse events were observed. CONCLUSIONS: Selective angiographic embolization of knee and elbow arteries is a feasible procedure that can prevent repetitive bleedings, which would translate in better joint outcomes for these patients.

Oral desensitisation with food is food-specific and protein-specific.

The avoidance of food(s) is the main therapeutic approach to food allergy. Nevertheless, orally- or sublingually-administered food allergens have gained attention and a number of food-allergic children can tolerate gradually increasing amounts of cow's milk and hen's egg. Our purpose is to show that oral desensitisation with food is an allergen-specific therapeutic approach and for this, we describe 4 illustrative children with IgE-mediated food allergy. The first was allergic to cow's milk and hen's egg, the second to cow's milk, hen's egg and fish. Both underwent oral desensitisation to both cow's milk and hen's egg. The third child was allergic to cow's milk, hen's egg and fish and underwent oral desensitisation with cow's milk. The last child was allergic to raw but not to cooked/boiled hen's egg and underwent the oral desensitisation with hen's egg. The first 2 children reached the clinical tolerance to cow's milk after the cow's milk oral desensitisation, but reached the hen's egg tolerance only after the hen's egg oral desensitisation. Moreover, the second child did not tolerate fish after being desensitised to both cow's milk and hen's egg. The third child tolerated cow's milk, but not hen's egg and fish, at the end of the cow's milk oral desensitisation. The fourth child could tolerate the previously not tolerated raw hen's egg after the oral desensitisation with raw hen's egg. In conclusion, we indicate that oral desensitisation with food is allergen specific. The induction of the clinical tolerance to one food is not followed by the tolerance to the other food(s) that the patient is allergic to. To obtain a double or multiple food tolerance, separate desensitisation protocols, one for each food, have to be carried out. Oral desensitisation with food discriminates between raw and cooked proteins.
