Clinical features of Kasabach-Merritt syndrome: an analysis of 16 neonates / 中国当代儿科杂志

OBJECTIVE@#To study the clinical features, treatment, and prognosis of neonates with Kasabach-Merritt syndrome (KMS), and to provide a reference for optimizing the diagnosis and treatment of this disease.@*METHODS@#A retrospective analysis was performed for the clinical and follow-up data of 16 neonates with KMS who were admitted to the Anhui Children's Hospital, Anhui Medical University, from January 2016 to December 2020.@*RESULTS@#Of the 16 neonates, there were 13 boys (81%) and 3 girls (19%), with an age of 1 hour to 10 days on admission. Among these neonates, 13 (81%) had cutaneous hemangioma (2 in the head and face, 5 in the trunk, and 6 in the extremities) and 3 (19%) had liver hemangioma. The main clinical manifestations of bleeding tendency and scattered petechiae and ecchymosis were observed in 10 neonates (62%). All the 16 neonates had varying degrees of thrombocytopenia and coagulation disorders. They all received glucocorticoid treatment after admission and 7 (44%) of them had response, among whom 4 experienced recurrence. Among the neonates with no response to glucocorticoid treatment, 3 received sirolimus treatment, among whom 1 had the tumor volume reduced by 58.8% after 4 weeks of treatment, with platelet count and coagulation function returning to normal, while 2 had no significant reduction in tumor volume or significant increase in platelet count and achieved a tumor volume reduced by (43.7±0.4)% after 4 weeks of combined treatment with bleomycin arterial embolization, with platelet count and coagulation function returning to normal. After 4 weeks of bleomycin arterial embolization alone for 4 neonates, tumor volume was reduced by (52.0±3.4)%, and platelet count and coagulation function returned to normal. Blunt and sharp dissection was performed for 2 neonates. The tumor was removed completely during surgery in the 2 neonates, with no infection or recurrence after surgery, and platelet count and coagulation function returned to normal. The postoperative pathological examination showed Kaposiform hemangioendothelioma in 1 out of the 2 neonates.@*CONCLUSIONS@#KMS has characteristic clinical manifestations, histopathological features, and laboratory examination results. The KMS neonates who are not sensitive to glucocorticoids can achieve a good curative effect through arterial embolization and sirolimus treatment.

Clinical significance of pain in patients with chronic heart failure / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>There is a paucity of studies investigating the clinical and biochemical characteristics of pain in chronic heart failure (CHF) patients. This study aimed to determine the clinical and biochemical characteristics and outcomes in Chinese patients with CHF and symptoms of pain.</p><p><b>METHODS</b>Sociodemographics, serum levels of creatinine, NT-proBNP, high-sensitivity C-reactive protein (hs-CRP), tumor necrosis factor (TNF)-α, interleukin (IL)-6 and IL-10, and two-dimensional echocardiographic left ventricular ejection fraction (LVEF) were determined in 305 patients with CHF. A questionnaire packet including the Brief Pain Inventory (BPI) and the Minnesota Living with Heart Failure Questionnaire (MLHFQ) was used to assess the degree of pain rated on a 0 - 10 scale and the quality of life (QOL). A six-minute walking test was performed during routine clinic visits. Major adverse cardiac events (MACE) were recorded; including all-cause or cardiac mortality and rehospitalization because of myocardial infarction, worsening heart failure or stroke at follow-up.</p><p><b>RESULTS</b>Pain occurred in 25.6% of CHF patients, and was more common when the New York Heart Association (NYHA) functional class was worse. More patients with pain were female in gender, and had more co-morbidities, lower LVEF, and shorter distance during the 6-minute walking test. Despite similar serum levels of creatinine, N-terminal prohormone of brain natriuretic peptide (NT-proBNP), IL-6 and IL-10, the TNF-α levels were higher and MLHFQ scores were greater in CHF patients with pain. At follow-up, CHF patients with moderate to severe pain (≥ 4 scale) had higher rates of all-cause and cardiac mortality and rehospitalization because of myocardial infarction, worsening heart failure or stroke. Multivariate regression analysis revealed that the presence of pain was an independent risk factor for MACE and reduced QOL in CHF patients.</p><p><b>CONCLUSIONS</b>Pain occurs in all stages of the CHF trajectory, and its incidence increases as clinical functional status is worsened. The presence of pain exerts a negative impact on clinical outcome and QOL in patients with CHF.</p>

Impact of potentially lethal ventricular arrhythmias on long-term outcome in patients with chronic heart failure / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Potentially lethal ventricular arrhythmias (PLVAs) occur frequently in survivors after acute myocardial infarction and are increasingly recognized in other forms of structural heart diseases. This study investigated the prevalence and prognostic significance of PLVAs in patients with chronic heart failure (CHF).</p><p><b>METHODS</b>Data concerning demographics, etiology of heart failure, NYHA functional class, biochemical variables, electrocardiographic and echocardiographic findings, and medical treatments were collected by reviewing hospital medical records from 1080 patients with NYHA II-IV and a left ventricular (LV) ejection fraction ≤ 45%. PLVAs were defined as multi-focal ventricular ectopy (> 30 beats/h on Holter monitoring), bursts of ventricular premature beats, and nonsustained ventricular tachycardia. All-cause mortality, sudden death, and rehospitalization due to worsening heart failure, or cardiac transplantation during 5-year follow-up after discharge were recorded.</p><p><b>RESULTS</b>The occurrence rate of PLVAs in CHF was 30.2%, and increased with age; 23.4% in patients < 45 years old, 27.8% in those between 45 - 65 years old, and 33.5% in patients > 65 years old (P = 0.033). Patients with PLVAs had larger LV size and lower ejection fraction (both P < 0.01) and higher all-cause mortality (P = 0.014) during 5-year follow-up than those without PLVAs. Age (OR 1.041, 95%CI 1.004 - 1.079, P = 0.03) and LV end-diastolic dimension (OR 1.068, 95%CI 1.013 - 1.126, P = 0.015) independently predicted the occurrence of PLVAs. And PLVA was an independent factor for all-cause mortality (RR 1.702, 95%CI 1.017 - 2.848, P = 0.031) and sudden death (RR 1.937, 95%CI 1.068 - 3.516, P = 0.030) in patients with CHF.</p><p><b>CONCLUSION</b>PLVAs are common and exert a negative impact on long-term clinical outcome in patients with CHF.</p>

Method selection from medical imaging examinations in evaluation of pelvic injury in forensic medicine / 法医学杂志

OBJECTIVE@#To table a proposal for select using the medical imaging methods to evaluate pelvic injury in forensic field, by studying the structure of pelvis and radiological methods in common use.@*METHODS@#A study of several cases of pelvic injury was done, in which biomechanics and classification of pelvic injury were analyzed, moreover imaging methods were compared with each other, such as fluoroscopy, X-ray photography, computerized tomography (CT) and so on.@*RESULTS@#Four cases of pelvic injury are all multiple injuries, confirmed by X-ray photography and CT examination approvingly.@*CONCLUSIONS@#Authors advocate that pelvic injury mechanism and biomechanics should be considered accordingly, multiple injuries should be attracted notice, so as to select suitable imaging methods to evaluate pelvic injury exactly.
