Diversity, distribution and antibiotic resistance of Enterococcus spp. recovered from tomatoes, leaves, water and soil on U.S. Mid-Atlantic farms.
MEDLINE, EMBASE, and Cochrane databases were searched from their inception dates to March 30, 2016. Screening by 2 authors resulted in 6626 abstracts, of which 50 articles met the inclusion criteria. Study quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool or American College of Cardiology Foundation/American Heart Association methodology.
Pyoderma gangrenosum is a rare neutrophilic dermatosis that affects 4% of children. It is characterized by its association in half of the cases with an underlying disease. The association with Behçet's disease is exceptional and may have a very poor prognosis. We report 2 pediatric observations with fatal outcome.
We present a case of interstitial nephritis and nephrogenic diabetes insipidus (NDI) in a patient treated with pemetrexed (500 mg/m(2)) for non-small cell lung cancer. Renal impairment and diabetes insipidus appeared after the first treatment cycle while he totally received four cycles of chemotherapy. There was not any significant myelosuppression and the patient was on regular supplementation with folic acid and vitamin B(12). He was not on any other medications and he did not receive any nephrotoxic agents. Kidney biopsy showed acute tubular necrosis together with interstitial inflammatory infiltrate of mononuclear cells and interstitial fibrosis occupying 25% of the cortex. There was not any improvement of renal function after a 2-week trial of oral prednisone. In the present case report, we review the literature for pemetrexed-induced renal toxicity and the possible mechanisms involved.
In this case report, we describe the successful implantation of multiple trabecular micro-bypass iStents in a patient with necrotizing scleritis.
Tyrosine-kinase inhibitors (TKIs) represent the only hopes for long-term survival for patients with chronic myeloid leukaemia (CML) and gastrointestinal stromal tumours. Thus, uninterrupted use of TKIs is of importance in such patients. Pure red cell aplasia (PRCA) is a rare disorder, not previously known to be associated with TKIs. We present, to the best of our knowledge, the first case of a patient with CML who developed PRCA secondary to both imatinib and nilotinib. Although PRCA was controlled on withdrawal of TKI, TKI continuation in the patient with CML is important. So we treated him with prednisone, but his haemoglobin started to drop on resumption of imatinib. He was changed to nilotinib but again developed PRCA, which did not improve with steroids. We treated him with cyclosporine and were able to reintroduce nilotinib at a reduced dose without further complications. This case report makes physicians aware of this rare complication of TKIs and also provides encouragement that PRCA could be controlled and TKI continued.
The aim of this article is to summarise the main management options suggested by American College of Rheumatology and discusses the role of the general practitioner in the diagnosis and early management of PMR.
Gene expression profiling and pathway impact analyses were done from pretreatment lymphoma tissue of 24 patients. The findings were validated immunohistochemically in an independent cohort of 81 patients. All patients were treated with the combination of rituximab and cyclophoshamide-doxorubicin-vincristine-prednisone chemotherapy. In addition, microarray was used to screen the genes differentially expressed between control and rituximab-stimulated B-cell lymphoma cells in culture.
Between 2000 and 2004, 492 evaluable patients (ages 1 to 18 years) enrolled; 473 patients (96%) achieved CR. Four hundred eight patients (86%) participated in the corticosteroid randomization and 384 patients (81%) in the EC-Asnase randomization. With 4.9 years of median follow-up, dexamethasone was associated with superior 5-year event-free survival (EFS; 90% v 81% for prednisone; P = .01) but higher rates of infection (P = .03) and, in older children, higher cumulative incidence of osteonecrosis (P = .02) and fracture (P = .06). ID EC-Asnase had superior 5-year EFS (90% v 82% for FD; P = .04), but did not reduce the frequency of asparaginase-related toxicity. Multivariable analysis identified both dexamethasone and ID EC-Asnase as independent predictors of favorable EFS.
IR and R-CHOP therapy achieved a complete remission (CR). CR has continued for 14 months at the time of writing. The maximum level of EBV DNA was 259 copies/μg DNA, but 2 months after these therapies, the level had decreased to normal. The patient had no impairment of pancreas and kidney graft functions.
We report a case of a 27-year-old man who presented with a slowly growing left testicular swelling associated with mild pain over a period of 3 months. He was evaluated by his family physician with scrotal ultrasound and testicular tumour markers. He was diagnosed and treated as epididymo-orchitis and managed with antibiotics. When he later presented to us, he had an enlarged left testis with normal spermatic cord. Scrotal Doppler evaluation showed a globally enlarged left testis and epididymis with increased vascularity in the left testis, with the right testis being normal. Testicular tumour markers were normal. Fine-needle aspiration cytology of the left testis was suggestive of lymphoma. Exploration through an inguinal approach was carried out and a Chevassu manoeuvre with frozen section study was performed, which was reported as non-Hodgkin's lymphoma. Left radical orchidectomy was performed. Histopathology reported diffuse large B-cell lymphoma, of a germinal centre type. Contrast CT of the abdomen, chest and brain were normal. Sperm cryopreservation was carried out. The patient was started on chemotherapy with cyclophosphamide, hydroxydaunorubicin, oncovin, prednisone (CHOP) regime.
