ACQUIRED NEONATAL SEVERE FACTOR II DEFICIENCY- TWO CASES REPORT

In present study two cases of transient acquired and isolated factor II deficiency associated with severe bleeding are reported. Two infants were involved in severe coagulopathy. The blood clot time (CT) in case 2 was excessively prolonged over 16 hours. One-stage prothrombin time (PT) was remarkable prolonged. Haemostatic markers analysis showed an isolated deficiency of factor II at 2.5% and 4.5% respectively. No inhibitory activity against factor II could be detected. We successfully treated the deficiency with vitamin K1 during 15 days. It was interesting that in the case 2 female baby the cause of vitamin K deficiency might be breast feed problem (nutrition deficiency) and/or poor absorption from bowel. Physiopathological laboratory results and therapeutic aspects of two patients were presented.

Prognostic indicators associated with progresses of severe dengue

Background Dengue usually progress abnormally, especially in the critical phase. The main causes of death were shock, severe bleeding and organ failure. The aim of our study was to evaluate prognostic indicators of severe dengue according to the phases of the disease progression. Methods A cross-sectional study was conducted from July to December 2017 at the National Hospital for Tropical Diseases and the Hospital for Tropical Diseases of Ho Chi Minh City. 326 patients, aged 6 years and over, including 99/326 patients with severe dengue and 227/326 patients with non-severe dengue, hospitalized in the first 3 days of illness, confirmed Dengue virus by the RT-PCR assay have been registered for the study. Clinical manifestations were monitored daily. The hematocrit, white blood cells, platelet, serum albumin, ALT, AST, bilirubin, prothrombin time (PT%, PTs), fibrinogen, aPTT, INR and creatinine were evaluated at two times: febrile phase and critical phase. Results Independent factors associated with severe dengue were identified on multivariate logistic regression models. During the first 3 days of the disease, the prognostic indicators were platelet count ≤ 100 G/L (OR = 2.2; 95%CI: 1.2–3.9), or serum albumin < 35 g/L (OR = 3.3; 95%CI: 1.8–6.1). From day 4–6, the indicator were AST > 400 U/L (OR = 3.0; 95%CI: 1.1–7.9), ALT > 400 U/L (OR = 6.6; 95%CI: 1.7–24.6), albumin < 35 g/L (OR = 3.0; 95%CI: 1.5–5.9), and bilirubin total >17 μmol/L (OR = 4.6; 95%CI: 2.0–10.4). Conclusion To predict the risk of patients with severe dengue, prognostic laboratory indicators should be indicated consistent with the progression of the disease. During the first 3 days of illness, prognostic indicators should be platelet count, or serum albumin. From the 4th - 6th day of illness, prognostic indicators should be AST, ALT, albumin, or bilirubin total.

Management of Pediatric Tumors With Vascular Extension

Background: Pediatric tumors can present with vascular extension to the inferior vena cava and right atrium, which impacts the surgical strategy and can be challenging during surgical treatment. Wilms tumor (WT) is the most common retroperitoneal tumor that can present with vascular extension, but also adrenal tumors, clear cell tumors from the kidney, and hepatoblastomas can present with this situation. Surgical aims include obtaining complete tumor resection without risk for patients, to avoid severe bleeding, cardiac arrest, and embolization, and to avoid cardiac bypass if possible.Objective: To describe and discuss the surgical strategies to deal with pediatric tumors with vascular extension and propose a protocol.Method: Retrospectivly review the experience of treating patients with vascular extension in a single institution, describing different scenarios and a decision making fluxogram based on the preoperative evaluation regarding the surgical techniques and the need for cardiac bypass that are adequate for each situation. Image studies are important to guide the surgical strategy. Depending on the quality of image available, computerized tomography (CT) or magnetic resonance imaging (MRI) can be enough to give the information needed for surgical decisions. Ultrasonography (US) with Doppler is helpful to confirm diagnosis and describes factors to guide the adequate surgical strategy, like the upper level extension and presence or absence of blood flow around the thrombus. Neoadjuvant chemotherapy is indicated in most cases, in order to reduce the upper level of extension (and avoid the need for cardiac bypass) and to lower the risk of embolization. The approach is based on the upper level of the thrombus and can include cavotomy or cavectomy, sometimes with cardiac bypass and cardiac arrest with hypothermia, when the thrombus reaches the diaphragmatic level or above. Pathology analysis of the thrombus can guide staging and the need for radiotherapy postoperatively.Results: A decision making fluxogram protocol is presented focusing on the surgical treatment of such condition.Conclusion: Surgery strategy is highly impacted by the presence of vascular extension in pediatric tumors. Surgeons should be aware of potential complications and how to prevent them. Such cases should be treated in reference centers.

Survival Benefit of Anticoagulation Therapy in End Stage Kidney Disease Patients with Atrial Fibrillation: A Single Center Retrospective Study

Background and Objectives: Although the need for anticoagulation to prevent thromboembolism is increasing and non-vitamin K antagonist oral anticoagulants (NOACs) have been tried, there is still controversy about the efficacy of anticoagulation in patients with dialysis. Materials and Methods: We retrospectively analyzed the risk and benefit of anticoagulation in dialysis patients with atrial fibrillation (AF). We retrospectively analyzed all data of 89 patients who received dialysis therapy and were diagnosed with AF. Among them, 27 received anticoagulation (11 warfarin and 16 apixaban 2.5 mg twice a day), while 62 received no anticoagulation. Results: In multivariate Cox regression analysis, compared to no anticoagulation treatment, anticoagulation treatment was associated with a low incidence of all-cause mortality (hazard ratios (HR) 0.36; 95% confidence interval (CI) 0.15–0.88). Compared to no anticoagulation treatment, more anticoagulation treatment patients experienced severe bleeding (HR 4.67; 95% CI 1.26–17.25) and any bleeding (HR 2.79; 95% CI 1.01–7.74). Compared to no anticoagulation, warfarin treatment patients were associated with a low incidence of all-cause mortality (HR 0.26; 95% CI 0.09–0.81) and a high incidence of severe bleeding (HR 4.85; 95% CI 1.12–21.10). All-cause mortality and bleeding were not significantly different between no anticoagulation and apixaban treatment patients. Conclusions: In dialysis patients with AF, anticoagulation therapy is associated with an increased incidence of severe bleeding, but anticoagulation therapy is associated with a low incidence of all-cause mortality. Individualized anticoagulation therapy with careful bleeding monitoring is needed in dialysis patients with AF.

Lung Transplantation following Emergency Pneumonectomy in a Polytraumatized 18-Year-Old

Introduction. On rare occasions, a pneumonectomy needs to be performed after a severe polytrauma. Statistically, this procedure increases the mortality rate to 50%. One option to reduce this high rate could be an organ transplantation if a matching organ can be found. However, the current literature lacks any documentation of such a case. One reason for this stems from the fact that regulations for organ transplantation are very restricted and rarely allow exceptions. In addition, the chance for survival of polytraumatized patients in need of organs in the acute phase of the therapy is often quite unsure. Case Presentation. In this paper, we present the case of an 18-year-old patient who was involved in a serious motorcycle accident. His injury severity score was 29, but he suffered from severe bleeding in his lung which made a pneumonectomy necessary. The procedure led to a severe deterioration of his overall condition. An ECMO therapy was initiated, which effectively only slowed the aggravation. Therefore, he was transferred to our clinic where he was stabilized temporarily. A few days later, his situation turned worse. Since he had no other chance of survival, he was scheduled for a lung transplantation and was assigned an organ. After the transplantation, he stabilized quickly and recovered almost completely. Discussion. In this report, we want to show that an exception to the rules for organ transplantation might make sense on rare occasions. However, to increase the chance for any success, patients must be transferred to highly specialized clinics capable of treating patients with severe conditions. This might be the only chance for those patients to survive.

Use of the HAS-BLED Score in Risk Stratifying Patients on Dual Antiplatelet Therapy After Coronary Stent

Objectives: Use of the HAS-BLED score in risk stratifying patients on dual antiplatelet therapy after stent placement. Methods & Results: 304 patients who underwent stent placement from June, 2018 to December 2018. There is 6,57% patients with medium & severe bleeding. Area under the curve of HAS-BLED score (AUC); PRECISE-DAPT score and CRUSADE were sequential 0.59; 0,79 and 0,84 (p=0,0001) at post-PCI procedures; were sequential 0,72; 0,94 và 0,88 (p=0,00001) at less than 6 months after PCI procedures, and were sequential 0,87; 0,73 và 0,70 (p=0,0068) at more than 6 months after PCI procedures. Conclusion: the HAS-BLED score was most useful for predicting bleeding in patients on on dual antiplatelet therapy after stent placement at more than 6 months after PCI procedures. PRECISE-DAPT score was most useful for predicting bleeding at less than 6 months after PCI procedures and CRUSADE score was most useful for predicting bleeding at post procedure.

Diagnosis, Response Assessment and Treatment Outcomes in Acute Myeloid Leukemia (AML)

Leukemia occurs when a person's entire bone marrow tissue space is occupied by cancer cells or blasts that are young, dysfunctional, undifferentiated, and proliferating cells. In this situation, there is no space left for the bone marrow to be able to produce normal blood cells such as platelets, red and white blood cells. These patients suffer from severe bleeding due to decreased platelets or due to a decrease in white blood cells, which are often diagnosed with dangerous infections that cause death in these patients. The exact cause of leukemias is not yet known, but a number of factors have been identified that play a role in the development of these cancers, including high doses of radiation or atomic radiation, prolonged exposure to certain chemicals, and some Mentioned viruses and some genetic diseases such as Down syndrome or underlying diseases.
