The recognition and nursing management of common oncological emergencies in children

An oncological emergency may be the initial presentation of a cancer, a sign of cancer progression, or a complication of cancer treatment. The most frequently encountered paediatric oncological emergencies include neutropenic sepsis, hyperleukocytosis, brain tumours presenting with raised intracranial pressure, tumour lysis syndrome and superior mediastinal syndrome. These are all life-threatening conditions that require urgent recognition and management. Health professionals working in an emergency department (ED) are likely to be involved in managing these children. This article brings together the current guidance and recommendations for these specific emergencies. It also includes two case studies that demonstrate the challenges health professionals can face while managing these situations. It is important that health professionals have an acute awareness of oncological emergencies. Confidence in recognising the presentations, diagnoses and initial management are essential because these conditions may be life-threatening and time critical.

Haemophagocytic Lymphohistiocytosis in a Malay infant: Rare, Old and Often Forgotten Disease

Haemophagocytic lymphohistiocytosis (HLH) is a rare disease but potentially life threatening clinical syndrome. It is caused by a multisystemic hyperinflammatory process secondary to severe hypercytokinemia with excessive and uncontrolled activation of the immune response. We report a case of familial HLH with no apparent causes in 6 months-old Malay girl presented with recurrent fever associated with severe anaemia and bleeding tendency requiring extensive treatment but refractory to the treatment which lead to mortality due to neutropenic sepsis indicating of poor prognosis of this disease. This familial type of HLH should be suspected in all children after excluding all the secondary causes with collective laboratory features and requiring extensive management as it associated with high mortality.

Intensive Care Antifungal Stewardship Programme Based on T2Candida PCR and Candida Mannan Antigen: A Prospective Study

Non-culture-based biomarkers may improve diagnosis and antifungal treatment (AFT) of invasive candidiasis (IC). We evaluated an antifungal stewardship programme (AFSP) in a prospective intensive care unit (ICU) study, which included T2Candida and Candida mannan antigen (MAg) screening of patients with sepsis and a high risk of IC. Patients with non-neutropenic sepsis and a high risk of IC from two large tertiary ICUs were prospectively included, during a one-year period. IC was classified as proven, likely, possible or unlikely. The AFSP, diagnostic values of T2Candida and MAg, and the consumption of antifungals were evaluated. An amount of 219 patients with 504 T2Candida/MAg samples were included. IC was classified as proven in 29 (13.2%), likely in 7 (3.2%) and possible in 10 (5.5%) patients. Sensitivity/specificity/PPV/NPV values, comparing proven/likely versus unlikely IC, were 47%/100%/94%/90% for BC alone, 50%/97%/75%/90% for T2Candida alone, and 39%/96%/67%/88% for MAg alone. For the combination of T2Candida/MAg taken ≤3 days after AFT initiation, sensitivity/specificity/PPV/NPV was 70%/90%/63%/93%. T2Candida/MAg contributed to early (<3 days) AFT initiation in 13%, early AFT discontinuation in 25% and abstaining from AFT in 24% of patients. No reduction in overall use of AFT during the study period compared with the previous year was observed. An AFSP based on T2Candida and MAg screening contributed to a reduction of unnecessary treatment, but not overall AFT use. The diagnostic performance of T2Candida was lower than previously reported, but increased if T2Candida was combined with MAg.

Does the introduction of a formal neutropenic sepsis protocol improve therapeutic radiographer confidence and competence at recognising sepsis within the radiotherapy department?

Aim: The aim of this service review was to review whether implementing a formal training package increased therapeutic radiographer confidence and competence in recognising neutropenic sepsis in radiotherapy patients. In addition, authors also investigated whether the introduction of a weekly National Early Warning Score (NEWS) protocol had been successful in identifying cases of neutropenic sepsis. Material and Methods: Therapeutic radiographer (n = 13) views on the new protocol were collected through an online questionnaire. A review of the clinical observation sheets of patients who received chemo-radiotherapy (n = 49) between 18 April 2019 and 31 October 2019 was undertaken. Information on disease site, NEWS scores, number of patients who had become neutropenic and action taken by therapeutic radiographers was collected. Results: The majority of respondents to the questionnaire found that training benefitted both professionals and patients. Some challenges were highlighted relating to increased workload. For patients receiving regular observations, NEWS scores ranged from 0 to 4. When a patient scored on NEWS, the most common score was 1 across all treatment sites except cervix. Findings: Implementing a neutropenic sepsis protocol appears to be beneficial to therapeutic radiographers as professionals, increasing their confidence in patient assessment and monitoring. Regular observations may help to identify deteriorating patients alongside clinical judgement and symptom reviews.

Do we overtreat patients with presumed neutropenic sepsis?

PurposeMany aspects of the management of neutropenic sepsis remain controversial. These include the choice of empiric antibiotic, the duration of antibiotic therapy and the possibility that very low-risk cases may be managed safely with oral rather than intravenous therapy.Study designRetrospective cohort study conducted in a district general hospital serving a population of 148 000 in south west Scotland.ResultsFifty one patients with cancer, whose neutrophil count was less than 1.0×109/L within 21 days of their last chemotherapy, were admitted as a medical emergency in 2019. All received antibiotic because of presumed neutropenic sepsis. A total of 4 patients had positive blood cultures (group 1), 12 patients had a clinical focus of infection but no clear pathogen (group 2), while 35 patients had neither (group 3). Group 3 patients were more likely to have a solid tumour, less likely to be febrile, had shorter time to neutrophil recovery and higher Multinational Association of Supportive Care in Cancer scores, though not all of these comparisons achieved statistical significance. Median intravenous plus oral antibiotic duration in group 3 patients was 9 days with median hospital stay of 7 days, raising the possibility of overtreatment. Retrospectively, 23 (66%) group 3 patients had MASSC Risk Index greater than 21 suggesting they were at low risk of complications.ConclusionsIt seems likely that many low-risk neutropenic cancer patients with solid tumours could be managed as effectively and as safely with shorter courses of antibiotic, with oral rather than intravenous antibiotic, as outpatients rather than inpatients and with an overall positive impact on antimicrobial stewardship.
