OBJECTIVE: This review aimed to familiarize pediatricians with the natural history, clinical manifestations, diagnosis, and management of AHEI.
METHODS: A PubMed search was conducted in February 2020 in Clinical Queries using the key terms "acute hemorrhagic edema of infancy" OR "Finkelstein disease" OR "Seidlmayer disease". The search strategy included meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews published within the past 10 years. Only papers published in the English literature were included in this review. The information retrieved from the above search was used in the compilation of the present article.
RESULTS: AHEI, a rare cutaneous leukocytoclastic small-vessel vasculitis, typically presents with palpable purpura, peripheral acral edema, and frequently with fever, most often in children between 4 and 24 months of age. A significant number of children experience prodromal symptoms of an upper respiratory infection. Fever is typically low grade and is present in approximately 50% of cases. The cutaneous lesions are characterized by rapid onset of small erythematous macules or papules that progress to well demarcated, annular, rosette, medallion-like, or targetoid purpuric plaques or ecchymosis in 24 to 48 hours. The skin lesions are typically palpable, nonpruritic, and symmetrically distributed. Sites of predilection include the face, auricles, and extremities. Edema is typically nonpitting and asymmetrical and occurs primarily on the dorsum of the hands and feet, the face, and the auricles. In spite of the acuteness and extent of the cutaneous findings, the child looks well and nontoxic. Systemic and/or visceral involvement are rare. The differential diagnosis is broad and includes, among others, Henoch-Schönlein purpura. It is crucial to distinguish AHEI from the other diseases since the management of these diseases is quite different. The clinical features of mimickers of AHEI are reviewed and clues to differentiate AHEI from these mimickers are highlighted..AHEI is a benign, self-limited disease with complete spontaneous recovery in one to three weeks in the majority of cases.
CONCLUSION: Recognizing this rare disease is important for the pediatrician to rapidly differentiate AHEI from other potentially serious diseases that require prompt therapy and monitoring. With rapid recognition of AHEI, unnecessary investigations and inappropriate interventions can be prevented and parental anxiety can be avoided.
METHODS: A cross-sectional diagnostic study was performed on patients who had undergone nasal endoscopy and allergy testing. Allergy status was determined by positive serology or epicutaneous testing. Endoscopy was reviewed by blinded assessors for middle turbinate head edema. Appearance was graded as either normal, focal, multifocal, diffuse, or polypoid edema. Receiver-operator (ROC) analysis, likelihood ratio (LR), sensitivity, specificity, and positive predictive value (PPV) were determined.
RESULTS: One hundred eighty-seven patients representing 304 nasal cavities were assessed (42% female, age 39.74 ± 14.7 years, 57% allergic). Diffuse edema (PPV 91.7%/LR = 8) and polypoid edema (PPV 88.9%/LR = 6.2) demonstrated the strongest association with inhalant allergy. Multifocal edema was used as a cut-off to represent inhalant allergy from ROC analysis, which demonstrated 94.7% specificity and 23.4% sensitivity. The PPV for multifocal was 85.1% and LR = 4.4.
CONCLUSION: Middle turbinate edema is a useful nasal endoscopic feature to predict presence of inhalant allergy and, although not sensitive, has excellent PPV.
MATERIALS AND METHODS: Snakebite patients were prospectively recruited between 2017 and 2019. All patients were examined with POCUS to locate edema and directly visualize and measure the arterial flow in the compressed artery. The presence of DRAF in the compressed artery is suggestive of ACS development because when compartment space restriction occurs, increased retrograde arterial flow is observed in the artery.
RESULTS: Twenty-seven snakebite patients were analyzed. Seventeen patients (63%) were bitten by Crotalinae snakes, seven (26%) by Colubridae, one (4%) by Elapidae, and two (7%) had unidentified snakebites. All Crotalinae bit patients received antivenom, had subcutaneous edema and lacked DRAF in a POCUS examination series.
DISCUSSION: POCUS facilitates clinical decisions for snakebite envenomation. We also highlighted that the anatomic site of the snakebite is an important factor affecting the prognosis of the wounds. There were limitations of this study, including a small number of patients and no comparison with the generally accepted invasive evaluation for ACS.
CONCLUSIONS: We are unable to state that POCUS is a valid surrogate measurement of ACS from this study but see this as a starting point to develop further research in this area. Further study will be needed to better define the utility of POCUS in patients envenomated by snakes throughout the world.
DESIGN: A questionnaire containing 47 questions was developed which encompassed clinical scenarios such as treatment response to anti-vascular endothelial growth factor and steroid, treatment side effects, as well as cost and compliance/reimbursement in the management of DME using a Dephi questionnaire as guide.
METHODS: An expert panel of 12 retinal specialists from Singapore, Malaysia, Philippines, India and Vietnam responded to this questionnaire on two separate occasions. The first round responses were compiled, analyzed and discussed in a round table discussion where a consensus was sought through voting. Consensus was considered achieved, when 9 of the 12 panellists (75%) agreed on a recommendation.
RESULTS: The DME patients were initially profiled based on their response to treatment, and the terms target response, adequate response, nonresponse, and inadequate response were defined. The panellists arrived at a consensus on various aspects of DME treatment such as need for classification of patients before treatment, first-line treatment options, appropriate time to switch between treatment modalities, and steroid-related side effects based on which recommendations were derived, and a treatment algorithm was developed.
CONCLUSIONS: This consensus article provides comprehensive, evidence-based treatment guidelines in the management of DME in Asian population. In addition, it also provides recommendations on other aspects of DME management such as steroid treatment for stable glaucoma patients, management of intraocular pressure rise, and recommendations for cataract development.
