Abstract
Interventional radiology brings extensive benefits to patients. Nevertheless, certain procedures may result in high doses of radiation, leading to health risks to occupationally exposed individuals (OEIs). Therefore, a more comprehensive risk analysis is essential to ensuring safety and minimising radiation exposures for all OEIs. The Toolkit for Safety Assessment (TOKSA) tool performs risk assessments based on the concepts described in 'General Safety Requirements' Part 3 (Radiation Protection and Safety of Radiation Sources: International Basic Safety Standards) and Part 4 (Safety Assessment for Facilities and Activities). This tool was developed based on the 'Ibero-American Forum of Radiological and Nuclear Regulatory Agencies' risk models and can promote the use of the risk assessment processes by OEIs. The aim of this study was to experimentally analyse the applicability of the TOKSA tool in interventional radiology with the use/support of probabilistic risk assessment techniques. The results were used to reduce the risks associated with a hemodynamics room in a hospital in Belo Horizonte, Brazil.

Abstract
Abstract
Background
Statins are a cornerstone therapy for management of hypercholesterolaemia in primary and secondary prevention of cardiovascular disease, however there is individual variation regarding efficacy of therapy and adverse side-effects experienced.
Purpose
Polymorphisms of the SLCO1B1 gene have shown correlation with the risk of statin side-effects and efficacy of treatment, however in real-world clinical practice, their utility remains to be established.
Methods
We carried out retrospective multiple linear regression analysis using robust standard errors of 129 individuals undergoing genetic testing for the SLCO1B1 polymorphisms rs4149056 and rs2306283 to investigate for an association to statin side effects and efficacy respectively. In addition, logistic regressions which account for the binary nature of the outcomes were performed. The rs4149056 gene has 3 outcomes: T/T (considered least associated with statin intolerance), C/C (considered most associated with statin intolerance) and T/C (considered intermediately associated with statin intolerance). The rs2306283 gene has 3 outcomes: A/A (considered least associated with statin response), G/G (considered most associated with statin response) and A/G (considered intermediately associated with statin response).
Results
According to multiple regression and logistic regression analyses SLCO1B1 rs4149056 genotypes (C/C and T/C relative to the base type T/T) do not predict the incidence of myalgia, myopathy, creatine kinase rise, liver function derangement or gastrointestinal side effects at 5% significance. SLCO1B1 rs2306283 (G/G and A/G relative to the base type A/A) do not predict LDL response to statins (p-values 0.33 and 0.52 respectively).
Conclusions
The presence of rs4149056 C/C and T/C genotypes was not associated with an increased risk of statin side-effects. Similarly rs2306283 genotypes did not correlate with the efficacy of statin treatment. These genotype predictors were primarily based on Simvastatin – an earlier generation statin, whereas the majority of the patients in this cohort were treated with more contemporary and widely used statins such as Atorvastatin and Rosuvastatin. We therefore conclude that these genotypic markers may have limited application in modern day clinical practice and that substantial investment of limited resources towards them may not be justified.

Abstract
BackgroundPatients with rheumatoid arthritis (RA) on methotrexate have reduced vaccine responses. Temporary discontinuation has improved immunogenicity of anti-influenza vaccine, but this strategy has not been evaluated in anti-SARS-CoV-2 vaccines.ObjectivesTo evaluate the effect on immunogenicity and safety of 2-week methotrexate (MTX) discontinuation after each dose of the Sinovac-CoronaVac vaccine versus MTX maintenance in rheumatoid arthritis (RA) patients.MethodsThis was a single-center, prospective, randomized, investigator-blinded, intervention study (#NCT04754698, CoronavRheum), including adult RA patients (stable CDAI≤10, prednisone ≤7.5mg/day), randomized (1:1) to withdraw MTX (MTX-hold) for 2 weeks after each vaccine dose or maintain MTX (MTX-maintain), evaluated at D0, D28 and D69. Co-primary outcomes were anti-SARS-CoV-2 S1/S2 IgG seroconversion(SC) and neutralizing antibody (NAb) positivity at D69. Secondary outcomes were geometric mean titers (GMT) and flare rates. For immunogenicity analyses, we excluded patients with baseline positive IgG/NAb, and, for safety reasons, those who flared at D28 (CDAI>10) and did not withdraw MTX twice.ResultsRandomization included 138 patients with 9 exclusions (5 COVID-19, 4 protocol violations). Safety evaluation included 60 (MTX-hold) and 69 (MTX-maintain) patients. Further exclusions: 27 patients [13 (21.7%) vs. 14 (20.3%), p=0.848] with positive baseline IgG/NAb and 10 patients (21.3%) in MTX-hold with CDAI>10 at D28. At D69, MTX-hold (n=37) had a higher rate of seroconversion than MTX-maintain (n=55) group [29 (78.4%) vs 30 (54.5%), p=0.019], with parallel augmentation in GMT [34.2 (25.2-46.4) vs 16.8 (11.9-23.6), p=0.006]. No differences were observed for NAb positivity [23 (62.2%) vs 27 (49.1%), p=0.217]. At D28 flare, rates were comparable in both groups (CDAI, p=0.122; DAS28-CRP, p=0.576), whereas CDAI>10 was more frequent in MTX-hold at D69 (p=0.024).Figure 1.ConclusionWe provide novel data that 2-week MTX withdrawal after each Sinovac-CoronaVac vaccine dose improves anti-SARS-CoV-2 IgG response. The increased flare rates after second MTX withdrawal may be attributed to the short-term interval between vaccine doses. This strategy requires close surveillance and shared decision making due to the possibility of flares.References[1]Jara A, Undurraga EA, González C, et al.

Abstract
BackgroundWe recently reported an attenuate immunogenicity in patients with autoimmune rheumatic diseases. However, the effect of spondyloarthritis (SpA) and its treatment on COVID-19 vaccine immunogenicity remains to be determined for this group of patients. We therefore aimed to evaluate humoral immune responses to inactivated SARS-CoV-2 vaccine (CoronaVac) in patients with SpA (axial spondyloarthritis and psoriatic arthritis) taking DMARDs and commonly used targeted biological therapies, compared with a control group(CG).ObjectivesEvaluate immunogenicity and safety of CORONAVAC (Sninovac, Beijing) in Spondyloarthritis (SpA) patients.MethodsProspective observational cohort patients diagnosed with 194 SpA and 183 CG were vaccinated with CoronaVac in two doses with a 28-days interval. 194 patients completed the study and could be paired with CG for immunogenicity analysis. Blood samples were collected in the days 0, 28 and 69 (D69) to evaluate anti-SARS-CoV-2 IgG seroconversion(SC) and presence of neutralizing antibodies (NAb) in participants with negative IgG and NAb at baseline.ResultsPatients and GC were comparable regarding age (p=0.93) and sex (p=1.00). Immunogenicity at D69 showed a moderate/high SC (80.2% vs. 95.7%, p<0.0001) and Nab positivity (61.6% vs. 82.7%, p<0.0001) in SpA but lower than CG. Factors associated with lower immunogenicity were older age (56.8 vs. 51.4;p=0.03318) and higher frequencies of prednisone (25.7% vs 4.2%; p=0.0004), methotrexate (51.4% vs 40.1%, p=0.0016) and TNF inhibitor (TNFi) (62.9% vs 34.5%, p=0.0035). Likewise, prednisone (17.6% vs. 2.8%, p=0.0013) and TNFi (50% vs 33.9%; p=0.0408) were associated with diminished NAb positivity. Sulfasalazine was associated with higher SC rates (8.6% vs. 26.8%, p=0.0246) and NAb positivity (13.2% vs. 29.4%, p=0.0168). The multivariate analysis revealed that older age (p=0.037), prednisone (p=0.001), TNFi (p=0.016), and methotrexate(p=0.017) were independently associated with lower SC while prednisone (p=0.006) and TNFi (p=0.027) were also associated with reduced NAb response.ConclusionOur finding of an excellent safety and moderate/high SC rate in SpA supports the recommendation of CoronaVac vaccination. The impaired immune response in the minority of patients under immunosuppressive and biological therapy requires novel strategies to enhance antibody response in this subgroup of patients.References[1]Weaver A, Troum O, Hooper M, Koenig AS, Chaudhari S, Feng J, et al.

Abstract
During pregnancy, the maternal immune system is challenged to tolerate a semi-allogenic fetus. A shift toward a tolerogenic profile is essential to ensure a healthy fetal and placental development. One of the most important mechanisms involved in the maternal immune tolerance towards the fetal antigens is expressed in the activity of the regulatory T (Treg) and Th17 cells. The behavior and equilibrium of these two T lymphocyte populations were rarely studied in normal healthy pregnancies through the beginning of gestation to the postpartum period. We conducted a prospective longitudinal observational study where peripheral blood lymphocyte subsets were analyzed in each trimester of pregnancy and postpartum period in a group of healthy pregnant women. Our study observed a consistent reduction in peripheric Treg cell count through all pregnancy while the Th17 cell count remained stable. The Th17/Treg ratio increases significantly throughout pregnancy to the postpartum period. These changes could be justified by the migration of the immunotolerant Treg cells to the maternal decidua and lead to the establishment of a systemic pro-inflammatory profile by the end of pregnancy. This data could explain why systemic syndromes like preeclampsia develop in susceptible women during the second half of pregnancy or why many autoimmune disorders flourish in the first weeks postpartum.

Abstract
Background:Abatacept (ABA) can induce decrease in gamma-globulins, but the long-term safety of such reduction is unknown. Moreover, it is suggested that such decrease is dissociated from disease activity response.Objectives:To evaluate ABA-induced gamma-globulins reduction and its correlation with disease activity control and the risk of infection in rheumatoid arthritis(RA) patients.Methods:This is a retrospective inception cohort of RA patients undergoing ABA for the first time in a large single tertiary cohort (2007 to 2019). Patients were evaluated regarding clinical and inflammatory data, total and specific (IgG, IgM, IgA) gamma-globulins assessed before, at 3 and 6 months, and then every 6 months up to discontinuation/censoring. The occurrence of severe or recurrent infections as cause of discontinuation of treatment was recorded. All patients were submitted to a systematic infectious screening protocol before and during treatment.Results:One hundred seventy-nine RA patients were included. They were predominantly female (93%;n=167) and had a positive rheumatoid factor (RF, 84%; n=151). Median(range) age and disease duration were 55.1(17-81.3) and 14(1.6-39.8) years, respectively. ABA was used in median as the 3rd(1-8) bDMARD. Most patients (74.3%, n=134) had already used a TNFi previously and 34.1% (n=61) had failed to rituximab. Baseline DAS28 [median(range)] was 4.9 (2-8.62), CDAI 27(5-66), HAQ 1.5 (0-3), ESR 18(2-111), and CRP 8.1(0.1 -135.7). Levels of total gamma-globulins(TGG) were 1.2 (0.5-2.8g/dL), IgG 1,094(422-2,785mg/dL), IgM104(19-405 mg/dL), and IgA 324 (100-739mg/dL). Forty-five patients (25.1%) had low IgG before ABA, but only 8(4.5%) had IgG<600mg/dL and low TGG. At 3 months, remarkable decreases were observed in total gamma-globulin(1.2vs.1.1g/dL), IgG(1,094vs.992mg/dL), IgM(104vs.93mg/dL), and IgA(324vs.302mg/dL), in comparison to baseline(p<0.05). Longitudinal measurements demonstrated that levels of gamma-globulins remained stable for subsequent evaluations(p>0.05). At baseline, TGG, IgG, IgM and IgA correlated positively to all disease activity parameters: DAS28(r=+0.33; r=+0.31;r=+0.24 and r=+0.37, respectively; p<0.02 for all), SDAI (r=+0.35; r=+0.37; r=+0.43; r=+0.34, respectively; p<0.04 for all), CDAI (r=+0.32; r=+0.29; r=+0.39; r=+0.31, respectively; p<0.03 for all, except IgA), swollen joints (r=+0.24; r=+0.23; p<0.01 only for TGG and IgG, respectively); tender joints (r=+0.18; r=+0.21; p<0.04 only for IgG and IgM respectively), ESR (r=+0.35; r=+0.24; r=+0.41; p<0.02 for TGG, IgG and IgA, respectively) and CRP (r=+0.20; r=+0.16; r=+0.27; p<0.05 for TGG, IgG and IgA, respectively). Longitudinally, most of these correlations were lost(p>0.05). Moreover, at 6 months, 25 patients (14%) achieved DAS28 ≤ 2.6 and 49 (27.4%) had low disease activity (DAS28 ≤ 3.2). Baseline or longitudinal measures of TTG and subtypes were similar among patients who responded and those who did not, regardless of the cut-off used(p>0.05. Only 14 patients (9.4%) had the medication discontinued due to infections: 3 due to recurrent infections and 11 to severe infections. One patient died. The frequencies of low IgG (under the normal limit of normality) at baseline and all time points(p>0.05) were similar among patients with and without severe/recurrent infections. None of these patients had low TGG or very low IgG(<600mg/dL) at baseline or during treatment and the levels of TGG and all subtypes were comparable at all time points (p>0.05).Conclusion:This cohort of real-world RA patients shows that reduction in gamma-globulin levels induced by ABA is safe, non-progressive and not associated to a higher risk of infection, even in patients with low IgG or TGG. Additionally, it is not associated to clinical response.Disclosure of Interests: None declared

Abstract
OBJECTIVE Undernutrition is an important cause of morbidity and mortality in infants and children worldwide. The aim of this study was to evaluate the nutritional status and their predictors in children from 0 to 5 years of age in São Tomé. STUDY DESIGN A cross-sectional study was conducted in São Tomé Island. METHODS A total of 1285 individuals were enrolled between January and May 2011. Children were measured, and height for age (HAZ), weight for height (WHZ) and body mass index (BAZ) Z-score were computed. Global acute undernutrition is defined as weight for height <-1 Z-score (wasting < -2 Z-scores) and global chronic undernutrition as length/height for age <-1 Z-score (stunting < -2 Z-scores). Relevant information was collected from individual health bulletins, namely gestational age and birth weight, as well as weight at 6, 12, 18 and 24 months for all individual above these ages. Mothers were invited to answer a specific questionnaire. RESULTS A high percentage of global acute undernutrition (30.9% in <24 months and 21.9% in ≥24 months) and global chronic undernutrition (32.5% in <24 months and 41.1% in ≥24 months) was observed. Appropriate birth weight for gestational age (AGA) is significantly associated with lower odds for both acute (OR 0.485 [95% CI 0.299-0.785]) and chronic undernutrition (OR 0.427 [95% CI 0.270-0.675]) in children >12 months. Weight gain above 0.67 Z-score in the first semester of life was strongly related to lower odds for both acute (OR 0.109 [95% CI 0.040-0.291]) and chronic undernutrition (OR 0.379 [95% CI 0.187-0.770]) in children >12 months of age. Similarly, mother's education seems to protect against acute (>12 months: OR 0.448 [95% CI 0.244-0.825]; >24 months: OR 0.186 [95% CI 0.064-0.540]) and chronic undernutrition (>12 months: OR 0.389 [95% CI 0.232-0.653]; >24 months: OR 0.324 [95% CI 0.171-0.625]). All logistic regressions were adjusted for all children (gender, age, gestational age, birth weight, breastfeeding, begin consumption alcohol), mothers (age, height, body mass index, educational level, number of previous pregnancies, smoking during pregnancy, alcohol consumption during pregnancy) and household (number of siblings and persons at home) variables included in the protocol. CONCLUSIONS Birth weight, nutritional status, and the mother's education and weight gain particularly in the first year of life were important factors protecting against undernutrition during infancy and childhood. These results emphasize the importance of women's nutrition and of adequate birth weight and particularly weight gain during the first year of life in order to prevent wasting and stunting in childhood.

Abstract
The aim of this study was to determine the presence of virulence genes and antibiotic resistance profiles in 164 Escherichia coli strains isolated from birds (feral pigeons, hybrid ducks, house sparrows and spotless starlings) inhabiting urban and rural environments. A total of eight atypical enteropathogenic E. coli strains were identified: one in a house sparrow, four in feral pigeons and three in spotless starlings. Antibiotic resistance was present in 32.9% (54) of E. coli strains. The dominant type of resistance was to tetracycline (21.3%), ampicillin (19.5%) and sulfamethoxazole (18.9%). Five isolates had class 1 integrons containing gene cassettes encoding for dihydrofolate reductase A (dfrA) and aminoglycoside adenyltransferase A (aadA), one in a feral pigeon and four in spotless starlings. To our knowledge, the present study constitutes the first detection of virulence genes from E. coli in spotless starlings and house sparrows, and is also the first identification worldwide of integrons containing antibiotic resistance gene cassettes in E. coli strains from spotless starlings and pigeons.

Abstract
INTRODUCTION X-Linked agammaglobulinemia (XLA) is characterized by an arrest of B cell differentiation, leading to recurrent bacterial infections. Lifelong immunoglobulin replacement therapy (IRT) is indicated to prevent infections and their complications. MATERIAL AND METHODS A retrospective study of patients with XLA followed in a level three hospital was performed; data was collected retrospectively by review of clinical files. RESULTS XLA was diagnosed in 9 children. One (11%) had a positive family history with a prenatal diagnosis. Infection was the clinical presentation in all the others (89%), at an average age of 13 months; diagnosis was established at a mean age of 3.4 years. Acute otitis media (7/9) and pneumonia (5/9) were the most frequently observed. Seven (78%) presented serum immunoglobulin G (IgG) levels below 200mg/dL and all of them had CD19(+) B cells below 2%. Neutropenia was present at diagnosis in three patients (33%). Bruton tyrosine kinase (BTK) mutations were identified in all cases. Intravenous IRT was initiated, switched later to subcutaneous administration, in all. The mean time of follow-up was 10.7 years with cumulative time of 97 years. Eight children (89%) achieved IgG serum levels above 800 mg/dL. One presented lower values due to renal loss. No deaths occurred. After diagnosis the most frequent infections were acute otitis media (6/9). In spite of stable adequate IgG levels on IRT, two patients developed bronchiectasis. CONCLUSIONS XLA overall prognosis is good, as long as patients have an early and adequate treatment. However, bronchiectasis can occur even on adequate immunoglobulin replacement therapy.

Abstract
INTRODUCTION The accurate identification of sensitizing proteins in patients allergic to plant-derived foods is extremely important, allowing a correct dietary advice. We aimed to evaluate the diagnostic usefulness of skin prick tests (SPT) and specific IgE (sIgE) with single molecular allergen components in children with allergy to fruits and vegetables. METHODS Twenty children underwent SPT with a palm profilin (Pho d 2, 50 μg/mL); a Mal d 1-enriched apple extract (2 μg/mL) (PR-10 allergen); and a peach Lipid Transfer Protein (LTP) (Pru p 3, 30 μg/mL). Detection of sIgE to rBet v 1, rBet v 2, Phl p 12 and Pru p 3 was also measured. RESULTS Allergy to multiple fruits and vegetables was observed in 11 (55%) children. Sensitization by SPT to Pho d 2, Mal d 1, and Pru p 3 occurred in 5, 7, and 8 cases, respectively. LTP sensitization appeared to be associated with peach allergy but not with severe reactions, and profilins sensitization to melon and tomato allergy. Kiwi sensitization (12 cases), the plant-derived food that caused more allergic reactions, seemed mostly species-specific. The concordance of SPT extracts and sIgE to the corresponding pan-allergens was high for profilins (k=0.857) and LTP (k=0.706), while for PR-10 allergens it was absent (k=0.079). CONCLUSIONS Pan-allergen sensitization in children with allergy to fruits and vegetables was common and often multiple. There was no association of severe reactions to LTP sensitization. The introduction of routine SPT to pan-allergens can be a simple and feasible way of improving diagnostic and therapeutic efficacy.

Abstract
Microbial community composition was examined in two soil types, Anthrosols and adjacent soils, sampled from three locations in the Brazilian Amazon. The Anthrosols, also known as Amazonian dark earths, are highly fertile soils that are a legacy of pre-Columbian settlement. Both Anthrosols and adjacent soils are derived from the same parent material and subject to the same environmental conditions, including rainfall and temperature; however, the Anthrosols contain high levels of charcoal-like black carbon from which they derive their dark color. The Anthrosols typically have higher cation exchange capacity, higher pH, and higher phosphorus and calcium contents. We used culture media prepared from soil extracts to isolate bacteria unique to the two soil types and then sequenced their 16S rRNA genes to determine their phylogenetic placement. Higher numbers of culturable bacteria, by over two orders of magnitude at the deepest sampling depths, were counted in the Anthrosols. Sequences of bacteria isolated on soil extract media yielded five possible new bacterial families. Also, a higher number of families in the bacteria were represented by isolates from the deeper soil depths in the Anthrosols. Higher bacterial populations and a greater diversity of isolates were found in all of the Anthrosols, to a depth of up to 1 m, compared to adjacent soils located within 50-500 m of their associated Anthrosols. Compared to standard culture media, soil extract media revealed diverse soil microbial populations adapted to the unique biochemistry and physiological ecology of these Anthrosols.

Abstract
BACKGROUND IgE-mediated hypersensitivity reactions to Anisakis simplex have been described after ingestion of fish, suggesting that sensitisation to this parasite may induce acute urticaria and anaphylaxis. Anisakis simplex allergens are highly resistant to heat and freezing, and sensitisation may occur even in populations with low consumption of raw/undercooked fish. This study aimed to quantify the association between sensitisation to A. simplex and relapsing acute urticaria. METHODS This is the first case-control study on this topic. Cases (n = 200) were patients with a clinical diagnosis of relapsing acute urticaria, consecutively approached at the immunoallergology unit of Porto's largest paediatric hospital. Controls (n = 200) were consecutively selected at the surgery department of the same hospital, from subjects undergoing programmed orthopaedic, maxillofacial or general surgical procedures. Specific IgE measurements (Anisakis and Ascaris) were taken, and skin-prick tests (A simplex, common aeroallergens, fish, and Ascaris) were done. RESULTS Sensitisation to A simplex (OR 3.86, 95% CI 2.04% to 7.29%), Ascaris (OR 3.37, 95% CI 1.89% to 6.02%), fish (OR 4.62, 95% CI 1.85% to 11.52%), and at least one aeroallergen (OR 4.59, 95% CI 2.99% to 7.05%) were associated with increased risk of acute urticaria. Regarding the sensitisation to A simplex, the aeroallergen sensitisation-adjusted OR was 2.61 (95% CI 1.33% to 5.12%) for the whole sample, and 2.72 (95% CI 0.99% to 7.47%) for those not sensitised to Ascaris or fish. CONCLUSION Sensitisation to A simplex increases the risk of relapsing acute urticaria in subjects not sensitised to Ascaris or fish, and this is independent of aeroallergen sensitisation.

Abstract
We performed a serological study with sera from 92 patients with confirmed sporotrichosis registered between 1999 and 2004 in two hospitals in Rio de Janeiro State, Brazil. The clinical presentation of sporotrichosis was distributed as follows: lymphocutaneous, 67%; fixed cutaneous, 23%; disseminated cutaneous, 8%; and extracutaneous, 2%. Sera were assayed by ELISA against a cell wall antigen of Sporothrix schenckii, SsCBF, that we have previously described. The cross-reactivity was determined with 77 heterologous sera. The serological test showed a sensitivity of 90% and a global efficiency of 86%. A group of 55 patients with several clinical presentations of sporotrichosis was clinically and serologically followed-up for at least 6 months. We observed by ELISA data a decrease in the antibody serum titers which correlated with the progress in healing. An HIV-positive patient with meningeal sporotrichosis was serologically followed-up for over 2 years. Serum and cerebrospinal fluid specimens were examined and significant antibodies levels against the antigen SsCBF were detected. Our results strongly suggest that this serological test is valuable for the differential diagnosis and follow-up of all clinical forms of sporotrichosis.

Abstract
Prolidase deficiency is a rare, inherited disorder characterized by ulceration of the skin, mental retardation, and massive urinary excretion of imidodipeptides. Most patients also have recurrent infections, an unusual facial appearance, and splenomegaly. We describe a girl presenting with chronic dermatitis, recurrent respiratory tract infections since her first months of life, and facial features characteristic of prolidase deficiency. The diagnosis of prolidase deficiency was made at 4.5 months of age. The immunologic study in this patient showed an extreme and progressive increase of total immunoglobulin E (IgE) in serum (reaching the value of 77,600 IU/l) and defective chemotactic function of the neutrophils. Treatment with a hyper-proteic diet supplemented with ascorbic acid, manganese chlorite, and topical proline resulted in reduction of the frequency and severity of the infections and significant improvement of the skin lesions. The authors discuss the immunologic alterations and the favorable evolution with treatment in this patient.

Abstract
Spondylitis in childhood is rare, presenting a great variety of symptoms that are related to the child s age and to the site of the inflammatory process. We present the case of a nine-month-old infant, who presented to the emergency department with a torticollis of six weeks evolution. The diagnosis of spondylitis (C6-C7) was confirmed by MRI. Intravenous antibiotic therapy was administered. The patient showed complete regression of symptoms and imaging tests were normal. The rarity of this disease in patients in this age group, as well as the site and form of presentation are emphasised as is the importance of diagnosing this disease to prevent permanent neurological injuries or bone deformities.
