| 1 | Meckel's diverticulum masked by a long period of intermittent recurrent subocclusive episodes显示文摘Meckel's diverticulum(MD) is the most frequent congenital abnormality of the small bowel and it is often diff icult to diagnose.It is usually asymptomatic but approximately 4% are symptomatic with complications such as bleeding,intestinal obstruction,and inflammation.The authors report a case of a 7-year-old boy with a one-year history of recurrent periumbilical colicky pain with associated alimentary vomiting,symptoms erroneously related to a cyclic vomiting syndrome but not to MD.The clinical features and the differential diagnostic methods employed for diagnosis of MD are discussed. | Daniela Codrich Andrea Taddio Jurgen Schleef Alessandro Ventura Federico Marchetti | 2009 | World Journal of Gastroenterology2009，15，22： | 3 |
| 2 | Crohn's disease and Takayasu's arteritis: An uncommon association显示文摘Takayasu’s arteritis(TA)and Crohn’s disease(CD)are two rare autoimmune disorders;however some reports describe the presence of both diseases in the same patient.This finding has suggested the possibility that both diseases could share some common etiologic origin.We describe a case of a 13-year-old male affected by CD characterized by fever,diarrhea,weight loss,abdominal pain and elevation of inflammatory markers.Clinical and histological features from colonic specimens were consistent with CD.Treatment with steroids and azathioprine was started,however disease flared every time steroids were tapered.One year later,while still on treatment,he came back to our attention for dyspnea at rest and at night,tiredness and weakness.At physical examination a diastolic heart murmur was found as well as a left carotid artery bruit.A transthoracic echocardiography showed mild aortic valve insufficiency,left ventricular hypertrophy and a dilated ascending aorta with same findings at the aortic arch.A computed tomography scan showed abdominal aortathickening,dilated thoracic aorta and the presence of a thoracic aortic aneurysm.TA associated with CD was diagnosed and medical treatment with cyclophosphamide,steroids and aminosalicylic acid was started,with good clinical response at 6 mo follow-up.We discuss the presence of possible common causes for the two diseases and the importance of differential diagnosis in those patients characterized for intractable disease. | Andrea Taddio Massimo Maschio Stefano Martelossi Egidio Barbi Alessandro Ventura | 2013 | World Journal of Gastroenterology2013，19，35： | 3 |
| 3 | Failure of interferon-γ pre-treated mesenchymal stem cell treatment in a patient with crohn's disease显示文摘Mesenchymal stem cells(MSC) are cells of stromal origin which exhibit unlimited self-renewal capacity and pluripotency in vitro.It has recently been observed that MSC may also exert a profound immunosuppressive and anti-inflammatory effect both in vitro and in vivo with consequent potential use in autoimmune disorders.We present the case of a patient suffering from childhood-onset, multidrug resistant and steroiddependent Crohn's disease who underwent systemic infusions of MSC, which led to a temporary reduction in CCR4, CCR7 and CXCR4 expression by T-cells, and a temporary decrease in switched memory B-cells, In addition, following MSC infusion, lower doses of steroids were needed to inhibit proliferation of the patient's peripheral blood mononuclear cells.Despite these changes, no significant clinical benefit was observed, and the patient required rescue therapy with infliximab and subsequent autologous hematopoietic stem cell transplantation.The results of biological and in vitro observations after MSC use and the clinical effects of infusion are discussed, and a brief description is provided of previous data on MSC-based therapy in autoimmune disorders. | Andrea Taddio Alberto Tommasini Erica Valencic Ettore Biagi Giuliana Decorti Sara De Iudicibus Eva Cuzzoni Giuseppe Gaipa Raffaela Badolato Alberto Prandini Andrea Biondi Alessandro Ventura | 2015 | World Journal of Gastroenterology2015，21，14： | 2 |
| 4 | Neither hereditary periodic fever nor periodic fever, aphthae, pharingitis, adenitis: Undifferentiated periodic fever in a tertiary pediatric center显示文摘AIM To describe the frequency and clinical characteristics of patients with undifferentiated periodic fever(UPF) and to investigate whether a clinical classification of UPF based on the PRINTO-Eurofever score can help predicting the response to treatment and the outcome at follow-up.METHODS Clinical and therapeutic information of patients with recurrent fever who presented at a single pediatric rheumatology center from January 2006 through April 2016 were retrospectively collected. Patients with a clinical suspicion of hereditary periodic fever(HPF) syndrome and patients with clinical picture of periodic fever, aphthae, pharingitis, adenitis(PFAPA) who were refractory to tonsillectomy underwent molecular analysis of five HPF-related genes: MEFV(NM_000243.2), MVK(NM_000431.3), TNFRSF1 A(NM_001065.3), NLRP3(NM_001079821.2), NLRP12(NM_001277126.1). All patients who had a negative genetic result were defined as UPF and further investigated. PRINTO-Eurofever score for clinical diagnosis of HPF was calculated in all cases. RESULTS Of the 221 patients evaluated for periodic fever, twelve subjects with a clinical picture of PFAPA who were refractory to tonsillectomy and 22 subjects with a clinical suspicion of HPF underwent genetic analysis. Twenty-three patients(10.4%) resulted negative and were classified as UPF. The median age at presentation of patients with UPF was 9.5 mo(IQR 4-24). Patients with UPF had a higher frequency of aphthae(52.2% vs 0%, P = 0.0026) and musculoskeletal pain(65.2% vs 18.2%, P = 0.0255) than patients with genetic confirmed HPF. Also, patients with UPF had a higher frequency of aphthous stomatitis(52.2% vs 10.7%, P < 0.0001), musculoskeletal pain(65.2% vs 8,0%, P < 0.0001), and abdominal pain(52.2% vs 4.8%, P < 0.0001) and a lower frequency of pharyngitis(56.6% vs 81.3%, P = 0.0127) compared with typical PFAPA in the same cohort. Twenty-one of 23 patients with UPF(91.3%) received steroids, being effective in 16; 13(56.2%) were given colchicine, which was effective in 6. Symptoms resolution occurred in 2 patients with UPF at last follow-up. Classification according to the PRINTOEurofever score did not correlate with treatment response and prognosis. CONCLUSION UPF is not a rare diagnosis among patients with periodic fever. Clinical presentation place UPF half way on a clinical spectrum between PFAPA and HPF. The PRINTOEurofever score is not useful to predict clinical outcome and treatment response in these patients. | Silvia De Pauli Sara Lega Serena Pastore Domenico Leonardo Grasso Anna Monica Rosaria Bianco Giovanni Maria Severini Alberto Tommasini Andrea Taddio | 2018 | World Journal of Clinical Pediatrics2018，7，1： | 2 |
| 5 | Acute lobar nephritis in children: Not so easy to recognize and manage显示文摘Acute lobar nephritis(ALN) is a localized non-liquefactive inflammatory renal bacterial infection, which typically involves one or more lobes. ALN is considered to be a midpoint in the spectrum of upper urinary tract infection, a spectrum ranging from uncomplicated pyelonephritis to intrarenal abscess. This condition may be difficult to recognize due to the lack of specific symptoms and laboratory findings. Therefore the disease is probably underdiagnosed. Computed tomography scanning represents the diagnostic gold standard for ALN, but magnetic resonance imagine could be considered in order to limit irradiation. The diagnosis is relevant since initial intravenous antibiotic therapy and overall length of treatment should not be shorter than 3 wk. We review the literature and analyze the ALN clinical presentation starting from four cases with the aim to give to the clinicians the elements to suspect and recognize the ALN in children. | Cristina Bibalo Andrea Apicella Veronica Guastalla Pierluigi Marzuillo Floriana Zennaro Carmela Tringali Andrea Taddio Claudio Germani Egidio Barbi | 2016 | World Journal of Clinical Pediatrics2016，5，1： | 1 |
| 6 | Fever tree revisited:From malaria to autoinflammatory diseases显示文摘Over the centuries the idea of recurrent fevers has mainly been associated with malaria, but many other fevers, such as typhoid and diphtheria were cause for concern. It is only in recent times, with the more severe forms of fever from infectious origin becoming less frequent or a cause for worry that we started noticing recurrent fevers without any clear infectious cause, being described as having a pathogenesis of autoinflammatory nature. The use of molecular examinations in many cases can allow a diagnosis where the cause is monogenic. In other cases, however the pathogenesis is likely to be multifactorial and the diagnostic-therapeutic approach is strictly clinical. The old fever tree paradigm developed to describe fevers caused by malaria has been revisited here to describe today's periodic fevers from the periodic fever adenitis pharyngitis aphthae syndrome to the more rare autoinflammatory diseases. This model may allow us to place cases that are yet to be identified which are likely to be of multifactorial origin. | Serena Pastore Josef Vuch Anna Monica Bianco Andrea Taddio Alberto Tommasini | 2015 | World Journal of Clinical Pediatrics2015，4，4： | 1 |
