[Expression of p-AKT and p-mTOR in pediatric Burkitt lymphoma and their correlation with prognosis].

Objective: To evaluate the expression of p-AKT and p-mTOR, the key proteins in PI3K/AKT/mTOR pathway in pediatric Burkitt lymphoma (BL), and to investigate the clinical and prognostic significance. Methods: Fifty-eight cases of pediatric BL and thirty cases of reactive hyperplastic lymphadenitis (RH) were collected at Children's Hospital of Fudan University from September 2011 to July 2018. Paraffin sections of tissues were immune stained for p-AKT and p-mTOR, and the expression was assessed and correlated with the clinical features and prognosis. Results: A total of 58 cases were diagnosed an…

Yield of workup for patients with idiopathic presentation of the syndrome of inappropriate antidiuretic hormone secretion.

PURPOSE: To determine the proportion of patients for whom the syndrome of inappropriate antidiuretic hormone secretion (SIADH) is the presenting symptom of an underlying disorder, to describe the yield of different diagnostic modalities for patients with SIADH and an unknown etiology, and to define patients for whom such a workup is indicated. METHODS: A single center retrospective study including all patients diagnosed with SIADH without an apparent etiology in a large community hospital and tertiary center between 1.1.07 and 1.1.13. Two physicians reviewed every patient's medical file for p

Could familial Mediterranean fever gene mutations be related to PFAPA syndrome?

BACKGROUND: The cause and pathophysiology of PFAPA syndrome is unknown. The aim of this study was to determine all MEFV gene variants relevant to familial Mediterranean fever in children with PFAPA syndrome. METHODS: All MEFV gene variants were analyzed in patients with PFAPA syndrome. All patients were evaluated using the Gaslini scoring system. Serum immunoglobulin levels were also determined upon admission. RESULTS: We evaluated 64 patients with PFAPA syndrome. The median age at diagnosis was 37.5 (min-max: 6-96) months, and the percentage of male patients was 55.0%. The Gaslini diagnosti

[Protein expressions of Fas and FasL in B-cell lymphoma and their significances].

BACKGROUND & OBJECTIVE: Fas and FasL have been proved to be the inductional genes of cell apoptosis. Genesis of many tumors relates with functional disorder and abnormal expressions of Fas and FasL. This study was designed to detect protein expressions of Fas and FasL in B-cell non-Hodgkin's lymphoma (B-NHL) and benign lymphoid tissue, and to provide new markers for diagnosis of lymphoma. METHODS: Immunohistochemistry was used to detect protein expressions of Fas and FasL in 92 specimens of B-NHL, and 20 specimens of benign lymphoid tissue. RESULTS: Fas mostly expressed on membrane. FasL mos

Listeria monocytogenes and recurrent mycobacterial infections in a child with complete interferon-gamma-receptor (IFNgammaR1) deficiency: mutational analysis and evaluation of therapeutic options.

We describe the history of a girl with interferon-gamma-receptor (IFNgammaR1) deficiency and studies performed to identify the molecular and clinical characteristics of this recently discovered disorder. This is the first report of a child from Northern Europe with IFNgammaR1 deficiency. The patient, now 7 years old, first presented with swelling and reddening at the Bacille Calmette-Guerin (BCG) vaccination site, swelling of lymph nodes, hepatomegaly, and an unusually severe varicella rash at the age of 4 months. At that time, she was diagnosed with BCG histiocytosis without typical granuloma

Электронная добыча медицинских карт свидетельствует о воздействии иммунного состояния пациента на клинические результаты имплантации биоматериалов после повреждения мышечной ткани скелета.

Имплантация медицинских устройств и биоматериалов может помочь восстановить форму и функцию отсутствующей или поврежденной ткани. Известно, что иммунная система играет важнейшую роль как в позитивном, так и в негативном исходе этих имплантированных материалов. Реакция иностранного организма характеризуется осаждением белка и свертыванием, за которым следуют макрофагенное воспаление, расстройство фагоцитоза, образование гигантских клеток и, в конечном счете, фиброз. Это может препятствовать функционированию имплантированных устройств (например. Инсулиновые насосы), а также космезис (например, к

Clinical and genetic characterization of Japanese sporadic cases of periodic Fever, aphthous stomatitis, pharyngitis and adenitis syndrome from a single medical center in Japan.

PURPOSE: To investigate clinical presentation, genetic background and cytokine profile of Japanese sporadic cases of periodic fever, aphthous stomatitis, pharyngitis and adenitis (PFAPA) syndrome. METHODS: Nine PFAPA syndrome patients were recruited. DNA sequence analysis of auto inflammatory disorder susceptibility genes, MEFV, MVK, NLRP3, and TNFRSF1A, were performed. Serum cytokine levels and monocyte IL-1β levels were measured by ELISA. RESULTS: The study population consisted of six males and three females (mean age of onset 26.8 months). Febrile episodes lasted 3-6 days with symptom-fre

[Basic and clinical studies on tazobactam/piperacillin in pediatric field].

A drug susceptibility test of the combination drug TAZ/PIPC, which consists of a newly developed beta-lactamase inhibitor, tazobactam (TAZ), and one of penicillin antibiotics, piperacillin (PIPC), with combination ratio of 1:4 in potency, was conducted with stock strains and clinical isolates. The clinical efficacy and safety of its injection was also evaluated in children with a variety of infectious diseases. The results were as follows: 1. In susceptibility test, 114 strains from 4 species of stock strains were treated with 8 drugs, that is, TAZ/PIPC, PIPC, penicillin G (PCG), ampicillin (A

[Pseudotumoral abdominal granuloma concomitant with immune reconstitution after antiretroviral treatment].

BACKGROUND: Use of powerful multiple-drug antiretroviral regimens can significantly raise CD4+ counts restoring immune function, but in certain cases, leading to inflammatory reactions. CASE REPORT: An HIV-infected patient developed a mycobacteriosis of the digestive tract when his CD4 count fell below 5/mm3. He was given antimycobacterial treatment in combination with an effective triple antiretroviral regimen. At two years, the clinical situation was controlled with persistent optimal response (CD4 = 338/mm3 HIV-RNA < 500 copies/ml); the antimycobacterial regimen was discontinued. One year

Sensitivity and specificity of the individual CT signs of appendicitis: experience with 200 helical appendiceal CT examinations.

PURPOSE: Our goal was to determine the sensitivity, specificity, and diagnostic value of individual signs at helical appendiceal CT. METHOD: Two hundred helical appendiceal CT scans (100 appendicitis and 100 normal appendix cases) were interpreted for individual signs of appendicitis. Scan findings were correlated with appendectomy or clinical follow-up results. RESULTS: Individual CT signs identified and their sensitivity and specificity, respectively, included fat stranding (100%, 80%), enlarged (> 6 mm) unopacified appendix (93%, 100%), focal cecal apical thickening (69%, 100%), adenopath
