Neutrophilic dermatosis: a new skin manifestation and novel pathogenic variant in a rare autoinflammatory disease.

Sideroblastic anaemia, B-cell immunodeficiency, periodic fever and developmental delay (SIFD) is caused by mutations of TRNT1, an enzyme essential for mitochondrial protein synthesis, and has been reported in 23 cases. A 6-month-old girl was evaluated with recurrent fever, failure to thrive, skin lesions and anaemia. She received blood transfusions and empirical antibiotics. Skin lesions, previously interpreted as insect bites, consisted of numerous firm asymptomatic erythematous papules and nodules, distributed over trunk and limbs. Skin histopathology revealed an intense dermal neutrophilic infiltrate extending to the subcutaneous, with numerous atypical myeloid cells, requiring the diagnosis of leukaemia cutis, to be ruled out. Over the follow-up, she developed herpetic stomatitis, tonsillitis, lobar pneumonia and Metapneumovirus tracheitis, and also deeper skin lesions, resembling panniculitis. Hypogammaglobulinaemia was diagnosed. An autoinflammatory disease was confirmed by whole exome sequencing: heterozygous mutations for TRNT1 NM_182916 c.495_498del, p.F167Tfs * 9 and TRNT1 NM_182916 c.1246A>G, p.K416E. The patient has been treated with subcutaneous immunoglobulin and etanercept. She presented with developmental delay and short stature for age. The fever, anaemia, skin neutrophilic infiltration and the inflammatory parameters improved. We describe a novel mutation in SIFD and the first to present skin manifestations, namely neutrophilic dermal and hypodermal infiltration.

Sleep, quality of life and mood of nursing professionals of pediatric intensive care units.

OBJECTIVE: To assess sleep, quality of life and mood of nursing professionals of pediatric intensive care units. METHOD: Quantitative, cross-sectional and descriptive study. Professionals grouped by morning, afternoon and evening shifts were assessed by means of the instruments: Morningness-Eveningness Questionnaire; Pittsburgh Sleep Quality Index; Epworth Sleepiness Scale; Generic questionnaire for the assessment of quality of life (SF-36); Beck Depression Inventory; Beck Anxiety Inventory; State-Trait Anxiety Inventory. RESULTS: Sample consisted of 168 professionals, with prevalence of neutral typology (57.49%). There was no statistical significance regarding sleep, despite scores showing a poor quality of sleep and excessive daytime sleepiness for the three shifts. Quality of life did not reveal any statistical significance, but in the field "social role functioning" of the evening shift, a lower score was observed (p<0.007). There was no statistical significance regarding levels of anxiety and depression. CONCLUSION: The results suggest that these professionals may present sleeping problems, but they do not have lower scores of quality of life or mood disorders. Likely explanations for these findings may include an adaptation to their work type over time and the fact that working with children is rewarding. OBJETIVO: Avaliar sono, qualidade de vida e humor em profissionais de enfermagem em Unidades de Terapia Intensiva Infantil. MÉTODO: Estudo quantitativo, transversal e descritivo. Profissionais agrupados por turnos matutino, vespertino e noturno foram avaliados pelos instrumentos: Questionário de identificação Matutinidade-Vespertinidade; Índice de qualidade do sono de Pittsburgh; Escala de sonolência Epworth; Questionário genérico de avaliação de qualidade de vida - SF-36; Inventário de depressão de Beck; Inventário de ansiedade de Beck; Inventário de ansiedade Traço-Estado. RESULTADOS: Amostra composta por 168 profissionais, predominando tipologia neutra, 57,49%. Não houve significância estatística quanto ao sono, apesar dos escores mostrarem qualidade ruim e sonolência diurna excessiva para os três turnos. A qualidade de vida não denotou diferença estatística, mas no domínio "aspecto social" do turno noturno, observou-se escore pior (p<0,007). Não houve significância estatística nos níveis de ansiedade e depressão. CONCLUSÃO: Os resultados sugerem que estes profissionais podem apresentar problemas no sono, entretanto não apresentam escores mais baixos de qualidade de vida ou transtornos do humor. Possíveis explicações para estes achados são que haja uma adaptação ao regime de trabalho ao longo do tempo e que trabalhar com crianças seja recompensador.

Obesity resistance and multiple mechanisms of triglyceride synthesis in mice lacking Dgat.

Triglycerides (or triacylglycerols) represent the major form of stored energy in eukaryotes. Triglyceride synthesis has been assumed to occur primarily through acyl CoA:diacylglycerol transferase (Dgat), a microsomal enzyme that catalyses the final and only committed step in the glycerol phosphate pathway. Therefore, Dgat has been considered necessary for adipose tissue formation and essential for survival. Here we show that Dgat-deficient (Dgat-/-) mice are viable and can still synthesize triglycerides. Moreover, these mice are lean and resistant to diet-induced obesity. The obesity resistance involves increased energy expenditure and increased activity. Dgat deficiency also alters triglyceride metabolism in other tissues, including the mammary gland, where lactation is defective in Dgat-/- females. Our findings indicate that multiple mechanisms exist for triglyceride synthesis and suggest that the selective inhibition of Dgat-mediated triglyceride synthesis may be useful for treating obesity.

An Inpatient Geriatrics Program with a Focus on Any Type of Cognitive Impairment Reduces Mortality.

BACKGROUND: No matter what type of cognitive impairment an older hospitalized patient has, the risk of mortality is increased. OBJECTIVES: To describe a hospital-based geriatrics program with a focus on any type of cognitive impairment and to determine whether this program was associated with reduced mortality over time. DESIGN, PARTICIPANTS AND SETTING: Retrospective chart review of all patients age 70+ admitted during a 3-year period (2017-2019, N=20,401), to a 500-bed community-based hospital (Level 1 Trauma Center and Stroke Center). INTERVENTION: A multicomponent geriatrics program was developed and implemented throughout 2018 and included: geriatric consultation, data collection, review of the data with hospital leaders, a geriatrics task force, clinician education and a Delirium Unit. MAIN OUTCOMES AND MEASURES: Monthly mortality rates for patients with and without cognitive impairment over the 3-year period. To control for other variables associated with mortality, pre-post implementation analyses were performed (2017 versus 2019). RESULTS: A linear regression analysis showed a significant downward trend in mortality over time for patients with cognitive impairment [R2=0.4, P<.0001, (correlation coefficient -0.6, 95% CI, -0.8 to -0.4)] but not among patients without cognitive impairment [R2=0.0, P=0.829, (correlation coefficient 0.0, 95% CI, -0.3 to 0.3)]. When controlling for other variables, there was still a decrease in mortality risk among patients with cognitive impairment. CONCLUSION: Although there are limitations to this study, a multicomponent geriatrics program with an emphasis on any type of cognitive impairment, may be associated with improved mortality.

EARLY DETECTION OF POOR ADHERENCE TO TREATMENT OF PEDIATRIC RHEUMATIC DISEASES: PEDIATRIC RHEUMATOLOGY ADHERENCE QUESTIONNAIRE - A PILOT STUDY.

OBJECTIVE: To develop a questionnaire that allows the early detection of patients at risk for poor adherence to medical and non-medical treatment in children and adolescents with chronic rheumatic diseases. METHODS: The Pediatric Rheumatology Adherence Questionnaire (PRAQ) was applied in recently diagnosed patients within a period of one to four months after confirmation of the rheumatic disease. After six months, the patients' adherence to the medical and non-medical treatment was assessed. An internal consistency analysis was conducted to eliminate redundant questions in the PRAQ. RESULTS: A total of 33 patients were included in the pilot study. Six months after the PRAQ had been applied, poor global adherence was observed in seven (21.2%) patients and poor adherence to medical treatment in eight (24.2%) patients. No correlation was observed between the PRAQ scores and the percentages of adherence, as well as the stratification for each index, except for a tendency to a correlation between socioeconomic index and poor adherence to medical treatment (p=0.08). A new PRAQ questionnaire with 25 of the 46 original questions was generated as a result of the reliability analysis. CONCLUSIONS: The usefulness of this questionnaire in clinical practice should be still evaluated. Due to the importance of a tool for the early detection of rheumatic patients at risk of poor adherence to treatment, the new PRAQ questionnaire should be reviewed and applied in a larger study to better define its validity and reliability.

Psychological characteristics of caregivers of pediatric patients with chronic rheumatic disease in relation to treatment adherence.

BACKGROUND: Adherence to treatment for chronic diseases is lower in children than in adults, less extensively studied in children and is associated with multiple related factors. The aim of this study is to perform a descriptive analysis of psycho-cognitive aspects of primary caregivers of pediatric patients with chronic rheumatic diseases, as well as socioeconomic and clinical factors, family functioning and treatment satisfaction. METHODS: Primary caregivers of 90 patients were included. Pairs (caregiver plus patient) were grouped as presenting good adherence (n = 50) or poor adherence (n = 40) according to the Morisky Adherence Test. Psycho-cognitive aspects were evaluated by Adult Self-Report and Wechsler Adult Intelligence Scale tests. For statistical comparisons, quantitative variables with normal distribution were analyzed by Student's t test, and those with non-Gaussian distribution with the Mann Whitney test. Categorical variables were analyzed by Chi square test. A multivariate logistic regression analysis was performed to estimate the contribution of the independent variables to adherence. RESULTS: Compared to caregivers in the good adherence group, caregivers in the poor adherence group were more likely to be classified as clinical on the scales for attention problems and externalizing problems, which include impulsiveness and aggressiveness. They also scored higher on the depressive problem scale. In addition, the average number of children per caregiver and the mean age of caregivers and patients were significantly higher in the poor adherence group, while the proportion of caregivers with higher education was lower. The poor adherence group also included a higher incidence of pediatric patients assuming sole responsibility for managing medications. Economic status, clinical factors, treatment satisfaction, family functioning and caregiver cognitive profile were not related to adherence, except for working memory index. CONCLUSION: Older patients, patients as the one solely responsible for medication management, and caregivers with externalizing problems, were observed to be the most strongly associated to poor adherence. Interventions aimed at adolescent patients are needed. Also, psychological programs and interventional studies to better determine caregivers' behavioral/emotional status, and parent-child relationships are recommended.

Patients with juvenile idiopathic arthritis in clinical remission with positive power Doppler signal in joint ultrasonography have an increased rate of clinical flare: a prospective study.

BACKGROUND: Ultrasonography (US) studies carried out on joints of juvenile idiopathic arthritis (JIA) patients in clinical remission demonstrate the presence of subclinical synovitis. The significance of subclinical synovitis and the positive power Doppler (PD) signal on US in JIA in clinical remission is not well understood. The objectives of this study were to assess whether the changes detected by US in patients with JIA in clinical remission can predict disease flare and to evaluate factors associated with flare and joint damage over 30 months of follow-up. METHODS: A prospective study was performed with clinical and ultrasound evaluation in 34 joints of JIA patients in clinical remission. Clinical evaluation including physical exam, functional capacity and inflammatory markers was performed at baseline and every six months thereafter, for a total period of 30 months. US evaluation included presence of synovitis, PD signal and erosion at baseline and every 12 months thereafter. Subclinical synovitis was defined when there was synovitis with or without positive PD signal in US joints of patients in clinical remission. Flare was defined as any joint presenting clinical arthritis requiring therapy modification. RESULTS: We evaluated a total of 35 patients, 28 (80%) girls, 14 (40%) persistent oligoarticular subtype, 12 (34.3%) oligoarticular extended and 9 (25.7%) polyarticular and 26 (74.3%) in remission on medication. Twenty (57.1%) patients flared. The risk of flare was five times higher in patients with positive PD signal and 14 times higher in patients in remission on medication. Regarding the assessment of joints after 6 months and 12 months of US evaluation, 70/3162 (2.2%) joints and 80/2108 (3.8%) joints flared, respectively. Joints with subclinical synovitis with positive PD signal flared more after 6 and 12 months. Twenty five of 2108 (1.2%) joints showed erosion over time. Joints with subclinical synovitis with or without positive PD signal showed more erosion. CONCLUSIONS: Patients in remission on medication with subclinical synovitis with positive PD signal on US have a higher risk of flare, therefore they should be monitored closely during treatment. In the same way, joints with subclinical synovitis with or without positive PD signal should be monitored due to the risk of flare and joint damage.

Intra-articular injection in patients with juvenile idiopathic arthritis: factors associated with a good response. / Infiltração intra-articular em pacientes com artrite idiopática juvenil: fatores associados à boa resposta.

INTRODUCTION: Intra-articular injection of corticosteroids (IIC) for treatment of patients with juvenile idiopathic arthritis (JIA) is increasingly used in Pediatric Rheumatology. OBJECTIVES: To describe the clinical course of patients undergoing IIC in our Pediatric Rheumatology Unit. METHODS: Retrospective study of patients with JIA undergoing IIC from January 2008 to December 2012, with a minimum follow-up of six months after the injection. Good response to IIC was set as the presence of inactivity on the infiltrated joint by at least six months. RESULTS: Eighty-eight patients underwent a total of 165 IICs. Of these, 75% were girls and 35.2% had persistent oligoarticular JIA. The mean age at diagnosis was 6.8 years, and when IIC was carried out, 12.2 years. Regarding patients, younger age at diagnosis (p=0.037) and the occurrence of uveitis in the course of the disease (p=0.015) were associated with good response to IIC. From 165 IICs, 63% had a good response and joints remained inactive for a median of 18.1 months. The type of joint injection (p=0.001), lesser values stated in the overall visual analogue scale by the physician (p=0.015) and by parents/patient (p=0.01) have been associated with a good response to IIC. Nine adverse events (5.4%) were observed. CONCLUSION: In our study, more than half of the joints showed a good response to IIC. Younger patients at diagnosis and uveitis during the course of the disease had good response to IIC. Knees, wrists and elbows were the joints that best responded to IIC. IIC proved to be a safe procedure.

Hemodynamic evaluation by Doppler echocardiography of small (less than or equal to 21 mm) prostheses and bioprostheses in the aortic valve position.

To assess resting hemodynamics of an unselected group of patients with prostheses or bioprostheses sized less than or equal to 21 mm implanted into the aortic valve position during a 7-year period, 46 of 50 eligible patients were examined by Doppler echocardiography. The valves were Carpentier-Edwards (CE) supraannular 21 mm (n = 8), Medtronic-Hall (MH) 20 mm (n = 8) and 21 mm (n = 21), and the rest (n = 9) were other valves with only 1 to 3 patients in each group. Gradients, valve areas and dimensionless obstruction indexes (ratio of subvalvular/valvular velocities and velocity time integrals) were compared. By analysis of variance, gradients did not differ significantly between the CE supraannular 21 mm, the MH 20 and 21 mm prostheses (peak/mean 25 +/- 8/14 +/- 5, 31 +/- 13/16 +/- 6 and 25 +/- 10/13 +/- 5 mm Hg; p = not significant). Only 2 patients had a mean gradient greater than 25 mm Hg. The valve area was slightly larger for the MH 21 mm group compared with the CE supraannular 21 mm group (1.34 +/- 0.15 vs 1.16 +/- 0.14 cm2, p less than 0.05). The dimensionless obstruction indexes did not differ (CE supraannular 21 mm 0.36 +/- 0.07/0.40 +/- 0.07 (velocities/velocity time integrals), MH 20 mm 0.40 +/- 0.12/0.47 +/- 0.12, MH 21 mm 0.38 +/- 0.05/0.44 +/- 0.06; p = not significant).(ABSTRACT TRUNCATED AT 250 WORDS)

Leptin levels vary significantly during the menstrual cycle, pregnancy, and in vitro fertilization treatment: possible relation to estradiol.

OBJECTIVE: To evaluate the influence of sex steroids on leptin levels in patients with conditions in which the steroid levels are increased. DESIGN: Prospective study. SETTING: A hospital unit for reproductive medicine and a maternal care unit affiliated with the hospital and hospital staff. PATIENT(S): Thirteen women with regular menstrual cycles, 29 women with normal pregnancies, and 25 women undergoing IVF treatment. INTERVENTION(S): Blood samples were obtained during days 1-3, 6-8, 13-15, and 22-25 of the menstrual cycle in regularly cycling women and during gestational weeks 13, 20, 28, 32, and 36 and 7-13 weeks after birth in pregnant women. In women undergoing IVF treatment, blood samples were collected after E2 suppression, after ovarian stimulation, and at the time of ovum pickup. MAIN OUTCOME MEASURE(S): Serum levels of leptin, E2, and progesterone. RESULT(S): Leptin levels varied during the menstrual cycle and were elevated during pregnancy, with a peak during week 28. In the IVF group, leptin levels increased throughout the treatment cycle. Body mass index correlated positively with leptin levels in all three groups, and the maternal weight gain from weeks 13-32 tended to correlate with the rise in leptin levels. Estradiol levels correlated positively with leptin levels during E2 suppression. Negative correlations existed between the pregnancy-induced increases in E2 and leptin levels from weeks 13-32, and between the levels after birth. Leptin levels and progesterone levels did not correlate in any of the groups. CONCLUSION(S): Modest elevations of leptin levels were observed during IVF treatment and pregnancy. The increase in the IVF group indicates that factors other than body fat mass (possibly E2) also are of importance for the regulation of leptin levels.

Thrombotic disc impediment in a Medtronic-Hall aortic valve prosthesis diagnosed by Doppler echocardiography followed by successful reoperation.

A case with impeded disc movement caused by thrombus formation in a Medtronic-Hall aortic valve prosthesis is reported. A correct diagnosis, including both mechanism and severity of the prosthesis failure, was established by Doppler echocardiography. The patient was promptly referred for surgery without invasive or other supplementary investigations.

Anterior perforations in lumbar discectomies. A report of four cases of vascular complications and a CT study of the prevertebral lumbar anatomy.

Four cases of vascular complications to anterior perforations during discectomy prompted a CT study to measure lumbar disc diameters and to evaluate the prevertebral anatomy. Fifty young adults who had been referred for low-back pain and/or sciatica but had not undergone operation were included. In five additional patients, prone versus supine CT examinations were compared. Six typical configurations of the vascular anatomy could be classified to explain the type of vascular complications occurring at the L3-4 and L4-L5 disc levels. The sagittal diameter of the three lowest lumbar discs varied from 33 to 56 mm, indicating the importance of this parameter as an intraoperative guideline for the spine surgeon. Air-filled intestines were observed anterior to the L5-S1 disc predominantly in the prone position. The possible relationship between this finding and postoperative discitis is discussed.

Early detection of poor adherence to treatment of pediatric rheumatic diseases: pediatric rheumatology adherence questionnaire - a pilot study / Detecção precoce da má adesão ao tratamento em doenças reumáticas pediátricas: questionário de adesão em reumatologia pediátrica - estudo piloto

RESUMO Objetivo: Desenvolver um questionário que permitisse a detecção precoce de pacientes em risco de má adesão ao tratamento medicamentoso e não medicamentoso para crianças e adolescentes com doenças reumáticas crônicas. Métodos: O Questionário de Adesão em Reumatologia Pediátrica (QARP) foi aplicado em pacientes recentemente diagnosticados, de um a quatro meses após a confirmação da doença reumática. Seis meses depois, foi avaliada a adesão do paciente ao tratamento medicamentoso e não medicamentoso. Foi realizada uma análise de consistência interna para eliminar questões redundantes no QARP. Resultados: Ao todo, 33 pacientes foram incluídos no estudo-piloto. Seis meses após a aplicação do QARP, observou-se baixa adesão global em sete pacientes (21,2%) e baixa adesão ao tratamento medicamentoso em oito (24,2%) pacientes. Não foi encontrada correlação entre os escores QARP e as porcentagens de adesão, bem como a estratificação para cada indicador, com exceção de uma tendência a uma correlação entre o indicador socioeconômico e a baixa adesão ao tratamento medicamentoso (p=0,08). Um novo questionário QARP com 25 das 46 perguntas originais foi gerado como resultado da análise de confiabilidade. Conclusões: A utilidade deste questionário na prática clínica ainda deve ser avaliada. Devido à importância de uma ferramenta para a detecção precoce de pacientes reumáticos em risco de má adesão ao tratamento, o novo questionário QARP deve ser revisado e aplicado em um estudo maior para que sua validade e confiabilidade sejam mais bem definidas.

Association between the ultrasonographic and clinical findings in the hips of patients with juvenile idiopathic arthritis.

OBJECTIVE: To describe the ultrasonographic (US) findings in the hips of patients with juvenile idiopathic arthritis (JIA) and the association between these findings and the signs, symptoms, and activity of the disease. MATERIALS AND METHODS: The present retrospective study included 92 patients with JIA. The disease subtypes, age at disease onset, length of disease progression, disease activity, and clinical manifestations of the hip pathology were assessed. US examinations were routinely performed, and the images were analysed by two ultrasonographers who were blinded to the patients' clinical conditions. RESULTS: Of the 92 patients included in the study, 69.6% were girls, and the average age was 12.4 ± 5.1 years. Thirty-three (35.9%) participants exhibited the persistent oligoarticular subtype, and 30 (32.6%) exhibited the rheumatoid factor (RF)-negative polyarticular subtype. Forty-four participants exhibited signs and/or symptoms of hip pathology. Twenty-nine (31.5%) participants exhibited abnormal US findings, and 34.4% exhibited subclinical synovitis. The US alterations exhibited an association with subclinical synovitis in 34.4% of the cases. The US alterations bore a correlation with the presence of hip-related signs and/ or symptoms (P = 0.021), particularly joint limitations (P = 0.006), but were not correlated with the disease activity (P = 0.948) or subtype (P = 0.108). Clinical synovitis was associated with polyarticular involvement (P = 0.002) and disease activity (P = 0.017). Subclinical synovitis was not correlated with the investigated variables. CONCLUSION: Clinical affection of the hip in JIA, particularly joint limitation, is associated with synovitis (revealed by US assessment) independently of the activity and subtype of the disease. Therefore, healthcare professionals should consider the possible occurrence of silent disease and subclinical synovitis, which might contribute to hip deterioration.

RESUMO Introdução: A infiltração intra-articular de corticosteroides (IIC) para tratamento de pacientes com artrite idiopática juvenil (AIJ) é cada vez mais usada em reumatologia pediátrica. Objetivos: Descrever a evolução clínica dos pacientes submetidos à IIC em nosso setor de reumatologia pediátrica. Métodos: Estudo retrospectivo de pacientes com AIJ submetidos à IIC de janeiro/2008 a dezembro/2012, com seguimento mínimo de seis meses após a infiltração. Boa resposta à IIC foi definida como inatividade na articulação infiltrada por, no mínimo, seis meses. Resultados: Foram submetidos a 88 pacientes a 165 IICs. Desses, 75% eram meninas e 35,2% apresentavam AIJ oligoarticular persistente. A média de idade ao diagnóstico foi de 6,8 anos e à IIC de 12,2 anos. Em relação aos pacientes, a menor idade ao diagnóstico (p = 0,037) e a ocorrência de uveíte no curso da doença (p = 0,015) foram associados à boa resposta à IIC. Das 165 IICs, 63% apresentaram boa resposta e as articulações permaneceram inativas por um tempo médio de 18,1 meses. O tipo de articulação infiltrada (p = 0,001), menores valores na escala visual analógica global do médico (p = 0,015) e dos pais/paciente (p = 0,01) foram associados a uma boa resposta à IIC. Nove efeitos adversos (5,4%) foram observados. Conclusão: Em nosso estudo, mais da metade das articulações mostrou boa resposta à IIC. Os pacientes com menor idade ao diagnóstico e uveíte durante o curso da doença tiveram boa resposta à IIC. Os joelhos, punhos e cotovelos foram as articulações que mais bem responderam à IIC. A IIC mostrou ser um procedimento seguro.

Association between vitamin D levels and adolescent idiopathic scoliosis / Associação entre os níveis de vitamina D e a escoliose idiopática do adolescente / Asociación entre los niveles de vitamina D y la escoliosis idiopática do adolescente

Objective: To compare the levels of 25-hydroxyvitamin D in patients with AIS and a control group. Methods: The patients were recruited from the outpatient clinic of our institution during the year of 2013. Children diagnosed with scoliosis before 10 or after 18 years of age, and those suffering from neurological or muscular disorders, congenital malformations or genetic syndromes were excluded. The 25-OHD levels were determined by a fully automated electrochemiluminescence test. The appropriate level of 25-OHD was defined as greater than 30 ng/mL. The results were compared to a group of healthy individuals. Results: In group 1 (control) 63,3% showed abnormal vitamin D levels, while 91% of patients with AIS presented a low level of vitamin D. The mean BMI was 19.6 kg/m2 for controls and 20.3 kg/m2 for group 2. Statistical analysis showed significant difference (p<0.0001) between the levels of vitamin D. The average and minimum levels of vitamin D were respectively 27 and 13.6 ng/mL for group 1 and 18.8 and 3.13 ng/mL for AIS group. Conclusions: Patients with AIS had statistically significant lower levels of 25-OHD than healthy patients. Further research should be conducted to investigate the actual impact of serum vitamin D levels on the pathophysiology of AIS. .

Objetivo: Comparar os níveis de 25-hidroxivitamina D em pacientes com EIA e um grupo controle. Métodos: Os pacientes foram recrutados no ambulatório de nossa instituição durante 2013. Crianças com escoliose diagnosticada antes de 10 ou após 18 anos de idade, portadoras de distúrbios neurológicos ou musculares, deformidades congênitas ou síndromes genéticas foram excluídas. Os níveis de 25-OHD foram determinados por teste de eletroquimioluminescência totalmente automatizado. O nível adequado de 25-OHD foi definido como acima de 30 ng/ml. Os resultados foram comparados a um grupo de indivíduos saudáveis. Resultados: No grupo 1 (controle), 63,3 % apresentaram níveis anormais de vitamina D, enquanto 91% dos pacientes portadores de EIA apresentaram baixo nível de vitamina D. A média do IMC foi de 19,6 kg/m2 para os controles e 20,3 kg/m2 no grupo 2. A análise estatística demonstrou diferença relevante (p < 0,0001) entre os níveis de vitamina D. A média e os valores mínimos de vitamina D foram respectivamente 27 e 13,6 ng/ml para o grupo 1 e 18,8 e 3,13 ng/ml para o grupo EIA. Conclusões: Pacientes portadores de EIA tinham níveis de 25-OHD mais baixos do que os pacientes saudáveis, com significância estatística. O presente ...

Objetivo: Comparar los niveles de 25-hidroxivitamina D en pacientes con EIA y un grupo control. Métodos: Los pacientes fueron reclutados en el ambulatorio de nuestra institución durante el año de 2013. Se excluyeron los niños diagnosticados con escoliosis antes de 10 años o después de 18 años, y quienes sufren de trastornos neurológicos o musculares, malformaciones congénitas o síndromes genéticos. Los niveles de 25-OHD se determinaron mediante un ensayo de electroquimiolumniscencia totalmente automatizado. El nivel apropiado de 25-OHD se define como mayor que 30 ng/ml. Los resultados se compararon con un grupo de individuos sanos. Resultados: En el grupo 1 (control), 63,3% tenían niveles anormales de vitamina D, mientras que el 91% de los pacientes con EIA mostraron bajo nivel de vitamina D. El IMC promedio fue 19,6 Kg./m2 para los controles y 20,3 Kg./m2 para el grupo 2. El análisis estadístico mostró diferencias significativas (p < 0,0001) entre los niveles de vitamina D. Los valores medios y mínimos de vitamina D fueron respectivamente 27 y 13,6 ng/ml para el grupo 1 y 18,8 y 3,13 ng/ml para el grupo EIA. Conclusiones: Los pacientes con EIA tenían niveles más bajos de 25-OHD que los pacientes sanos, con significación estadística. Este estudio sugiere que la deficiencia ...

Associação entre achados ultrassonográficos e clínicos do quadril de pacientes com artrite idiopática juvenil / Association between the ultrasonographic and clinical findings in the hips of patients with juvenile idiopathic arthritis

OBJETIVO: Descrever os achados ultrassonográficos do quadril em pacientes com artrite idiopática juvenil (AIJ) e sua associação com sinais, sintomas e atividade da doença. MATERIAIS E MÉTODOS: Estudo retrospectivo com 92 pacientes com AIJ. Foram avaliados os subtipos da doença, a idade de início, o tempo de evolução, a atividade da doença e as manifestações clínicas do envolvimento do quadril. A avaliação ultrassonográfica foi realizada na rotina dos pacientes, e as imagens foram analisadas por dois ultrassonografistas cegos em relação às condições clínicas dos pacientes. RESULTADOS: Do total de 92 pacientes, 69,6% eram meninas, com média de idade de 12,4 ± 5,1 anos. Trinta e três (35,9%) apresentaram subtipo oligoarticular persistente e trinta (32,6%) poliarticular com fator reumatoide negativo. Quarenta e quatro (47,8%) apresentaram sinal e/ou sintoma relacionado ao quadril. Vinte e nove (31,5%) apresentaram alterações ultrassonográficas, com sinovite subclínica em 34,4%. As alterações ultrassonográficas se associaram com presença de sinais e/ou sintomas do quadril (P = 0,021), especialmente limitação articular (P = 0,006), mas não com atividade (P = 0,948) ou subtipo de doença (P = 0,108). Sinovite clínica se associou com comprometimento poliarticular (P = 0,002) e atividade de doença (P = 0,017). Não houve associação entre sinovite subclínica e as variáveis estudadas. CONCLUSÃO: O acometimento clínico do quadril na AIJ, especialmente a limitação articular, está associado à sinovite na avaliação por US, independente do subtipo e da atividade da doença. Os profissionais de saúde devem estar atentos à possibilidade de doença silenciosa com sinovite subclínica, que pode contribuir para a deterioração da articulação do quadril.

OBJECTIVE: To describe the ultrasonographic (US) findings in the hips of patients with juvenile idiopathic arthritis (JIA) and the association between these findings and the signs, symptoms, and activity of the disease. MATERIALS AND METHODS: The present retrospective study included 92 patients with JIA. The disease subtypes, age at disease onset, length of disease progression, disease activity, and clinical manifestations of the hip pathology were assessed. US examinations were routinely performed, and the images were analysed by two ultrasonographers who were blinded to the patients' clinical conditions. RESULTS: Of the 92 patients included in the study, 69.6% were girls, and the average age was 12.4 ± 5.1 years. Thirty-three (35.9%) participants exhibited the persistent oligoarticular subtype, and 30 (32.6%) exhibited the rheumatoid factor (RF)-negative polyarticular subtype. Forty-four participants exhibited signs and/or symptoms of hip pathology. Twentynine (31.5%) participants exhibited abnormal US findings, and 34.4% exhibited subclinical synovitis. The US alterations exhibited an association with subclinical synovitis in 34.4% of the cases. The US alterations bore a correlation with the presence of hip-related signs and/ or symptoms (P = 0.021), particularly joint limitations (P = 0.006), but were not correlated with the disease activity (P = 0.948) or subtype (P = 0.108). Clinical synovitis was associated with polyarticular involvement (P = 0.002) and disease activity (P = 0.017). Subclinical synovitis was not correlated with the investigated variables. CONCLUSION: Clinical affection of the hip in JIA, particularly joint limitation, is associated with synovitis (revealed by US assessment) independently of the activity and subtype of the disease. Therefore, healthcare professionals should consider the possible occurrence of silent disease and subclinical synovitis, which might contribute to hip deterioration.

Etiological misidentification by routine biochemical tests of bacteremia caused by Gordonia terrae infection in the course of an episode of acute cholecystitis.

Gordonia terrae has been reported to be a rare cause of bacteremia. We report the first case of bacteremia associated with acute cholecystitis. Commercial biochemical testing was not able to identify the strain at the genus level, classifying it instead as Rhodococcus sp. Definitive identification was obtained by sequencing of the 16S rRNA gene.

Intraoperative streptokinase in the treatment of superior mesenteric artery embolisation. Case report.

Two patients were treated with peroperative intra-arterial infusion of streptokinase in addition to embolectomy to improve blood perfusion and reduce the magnitude of bowel resection in embolism of the superior mesenteric artery. Perfusion of the bowel improved considerably during and after streptokinase infusion thereby avoiding major intestinal resection in both patients.
