Investigating the comparative effect of vitamin D level with the type of complications in Henoch Schönlein purpura and Kawasaki disease.

INTRODUCTION AND OBJECTIVES: Henoch Schönlein purpura (HSP) and Kawasaki disease (KD) are two main inflammatory diseases among childhood vasculitis. Considering the anti-inflammatory effects of 25-hydroxyvitamin D3, we decided to investigate the association of serum 25-hydroxy vitamin D3 level with the type and severity of these conditions. MATERIALS AND METHODS: The present study was performed as a historical cohort of 254 affected children with KD and HSP vasculitis. The required data were extracted, using a researcher-made questionnaire from patients' electronic file, and then they were analyzed after collecting information of the patients. RESULTS: In HSP group, 54% of participants were boys. Similarly, in KD group, boys were more affected than girls. The comparative 25-hydroxyvitamin vitamin D3 level in HSP patients with and without renal involvement (P=0.02), hematuria (P=0.14), and in two groups with and without heart disease, and also with and without coronary artery dilatation in KD patients (P<0.001) were significant. DISCUSSION AND CONCLUSIONS: The findings showed that insufficient level of vitamin D3 were significantly associated with the exacerbation of complications of both diseases, and therefore it seems that vitamin D deficiency can be an effective predictive factor of severity in HSP and KD patients.

Introducción y objetivos: La púrpura de Henoch-Schönlein (HSP) y la enfermedad de Kawasaki (EK) son dos patologías inflamatorias principales entre las vasculitis infantiles. Teniendo en cuenta los efectos antiinflamatorios de la 25-hidroxivitamina D3, decidimos investigar la asociación del nivel sérico de esta con el tipo y la gravedad de dichas afecciones. Materiales y métodos: El presente estudio se realizó como una cohorte histórica de 254 niños afectados con vasculitis por EK y HSP. Los datos requeridos se extrajeron mediante un cuestionario elaborado por un investigador del expediente electrónico de los pacientes y se analizaron después de recopilar la información de los usuarios. Resultados: En el grupo HSP, 54 y 46% de los participantes eran niños y niñas, respectivamente. De manera similar, en el grupo KD, los varones se vieron más afectados. El nivel comparativo de 25-hidroxivitamina D3 en pacientes con HSP con y sin afectación renal (p = 0,02), hematuria (p = 0,14), y en dos grupos con y sin enfermedad cardiaca, y en dos con y sin dilatación de la arteria coronaria en usuarios con EK (p < 0,001) fueron significativos. Discusión y conclusiones: Los hallazgos mostraron que los niveles insuficientes de vitamina D se asociaron significativamente con la exacerbación de las complicaciones de ambas enfermedades, por lo que parece que la deficiencia de vitamina D puede ser un factor predictivo eficaz de la gravedad en pacientes con HSP y EK.(AU

A dual H-type tracheoesophageal fistula; why not being repaired simultaneously? A case report and review of literature.

BACKGROUND: H-type Tracheoesophageal Fistula (TEF) is a particular type of congenital esophageal anomalies, in which patients present with non-specific symptoms that can result in delayed diagnosis. Here, we report two pediatric cases with a rarer variant called ?dual H-type TEFË®. CASE PRESENTATION: We present two cases of H-type TEF. The first was a 45-day-old boy with feeding problem and cyanosis while feeding, and the second was a three-month-old girl with cough and choking after feeding from the first day of birth. In both cases, two separate TEFs were detected during diagnostic evaluation by flexible bronchoscopy. Both were repaired simultaneously through a cervical incision. The first patient deteriorated 13 days after the surgery, disturbancing in acid-base balance and expired unfortunately. CONCLUSION: Hence, it is necessary to consider the possibility of double TEF in any newly diagnosed H-type TEF.

Midfoot Arthritis in Children: Is There Any Relation With Malignancy?

BACKGROUND: Musculoskeletal symptoms are a presenting manifestation in a number of lymphoproliferative disorders including leukemia, especially in children. Among these primary symptoms, midfoot arthritis seems to be an important alarm for malignancy in children. The aim of this study is evaluation association of midfoot arthritis with malignancy in children. METHOD: In this cross-sectional study, all medical records of patients with arthritis were identified and reviewed. All clinical and laboratory data were recorded in the information form and data were analyzed by SPSS 25 software. RESULTS: A total of 557 cases of arthritis were evaluated, of which 18 (3.2%) cases have primary symptoms of midfoot arthritis. Four of 18 patients (22.2%) had B-cell precursor acute lymphoblastic leukemia, that midfoot arthritis was their first manifestation. Also, their laboratory findings confirmed that platelet, lactic acid dehydrogenesis, and uric acid values were significantly higher in these children. Based on statistical evaluation, there was no significant difference between age and sex in these patients. CONCLUSION: According to the findings of the present study, it can be concluded that "midfoot arthritis" may be the first manifestation of leukemia in children even with a near-normal hematologic values.

Determination of diagnostic value (validity) leukocyte esterase (urine dipstick strip) in differentiating inflammatory arthritis from bacterial arthritis

Abstract Background: The current diagnostic cornerstone for septic arthritis contains gram stains, bacterial culture, and cell count with a differential of aspirated synovial fluid. Recently, a synovial leukocyte esterase (LE) test has been used for diagnosing septic arthritis. Since this test measures the esterase activity of leukocytes, there is always a dilemma for using this test in patients with inflammatory arthritis. Methods: We collected the synovial fluid specimens as part of the general diagnostic protocol for patients suspected of Juvenile Idiopathic Arthritis (JIA) or Septic Arthritis (SA). Each group included 34 patients. We compared the result of the synovial LE test with the result of the culture of each patient. Results: The mean ages of patients were 64.14 ± 31.27 and 50.88 ± 23.19 months in the JIA group and septic arthritis group, respectively. The LE test results were positive in 30 specimens, trace in 3 and negative in one in the first-time test and were positive in 31 specimens and trace in 3 in the second-time test, while it was negative in all patients with JIA. Hence, the sensitivity of the synovial LE test was 80.8%, the specificity, PPV, and NPV were 78.6, 70.0, 86.8% respectively based on a positive culture. Conclusion: The leukocyte esterase strip test can be used as a rapid, bedside method for diagnosing or excluding bacterial infections in different body fluids. The synovial LE test can be used as an accurate test to rapidly rule in or out an acute articular bacterial infection, even in patients with concurrent inflammatory arthritis.(AU)

Peripheral gangrene: A rare presentation of systemic lupus erythematosus in a child.

PATIENT: Female, 12 FINAL DIAGNOSIS: Antiphospholipid positive SLE Symptoms: Gangrene • Raynaud's phenomenon • autoamputation of the terminal phalanx of the second left hand finger MEDICATION: Prednisolone • mycophenolate mofetil • captopril Clinical Procedure: Renal Biopsy • treatment of lupus nephritis • control of hypertension Specialty: Pediatric rheumatology. OBJECTIVE: Unusual clinical course. BACKGROUND: SLE in children has many manifestations. In several studies on SLE in children, gangrene and Raynaud phenomenon have been described as a rare manifestation of SLE during its course in children. CASE REPORT: We present the case of a 12-year-old girl referred to our center, presenting with peripheral gangrene plus Raynaud's phenomenon, who proved to have SLE. Our patient was treated with steroids and mycophenolate mofetil. She appeared to respond to this combination judging by the disappearance of the digital cyanosis, appearance of extremity pulses, and return of renal function. CONCLUSIONS: This case highlights the importance of precise management and awareness of very rare manifestations of a common disease like SLE. Gangrene can be initial symptom of SLE in children. We recommend SLE evolution in all children with gangrene symptom.
