Antiphospholipid syndrome (APS) is a systemic autoimmune disorder characterized by arterial and/ or venous thrombosis accompanied by persistently elevated levels of antiphospholipid antibodies (aPLs). The aim of this study is to evaluate the pulmonary manifestations of APS and compare the levels of aPLs in patients with and without pulmonary involvement. We retrospectively reviewed the files of patients with the diagnosis of APS between October 2010 and May 2017. Demographic data, clinical, radiological and laboratory findings were recorded. The study included 67 patients (56 female/11 male) with a mean age of 39?±?13 years. Pulmonary manifestations such as parenchymal and/or vascular involvement were seen in 12 (17.9%) patients. The patients with and without pulmonary manifestations were not significantly different in terms of age (p?=?0.46), comorbidities (p?=?0.48) and APS duration (p?=?0.66). Acute pulmonary thromboembolism (PE) was determined in 11 (16.4%), alveolar hemorrhage in 2 (3%) patients. Four patients with acute PE (36%) developed chronic thromboembolic pulmonary hypertension (CTEPH). One patient developed both CTEPH and diffuse alveolar hemorrhage after acute PE during follow up. Antiphosholipid antibody IgM was highly positive in patients with PE compared to patients without PE (p?=?0.005). Other antibodies and lupus anticoagulant were not significantly different in patients with and without PE. None of the patients were deceased due to pulmonary manifestations of APS. PE was the most common pulmonary manifestation of APS. The development of CTEPH was high among APS patients. Patients with APS should be closely followed for the onset of PE and CTEPH.

Diaphragmatic hernias are the most common abnormalities of gastrointestinal system especially in elderly patients. The radiographic findings of diaphragmatic hernias on esophagram are well known, but when incidentally found in an asymptomatic patient on axial computed tomography (CT) sections, the appearance of diaphragmatic hernia may mimic many other conditions. Our purpose is to present the CT findings of sliding hernia in an incidentally found asymptomatic patient, and to differentiate it from the other abnormalities that can be located in the distal paraesophageal area with the same appearance characteristics. 相似文献

Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal tract, and the majority contain KIT or PDGFRA-activating mutations. However, up to 10% of GISTs are c-kit-negative. Antibodies with increased sensitivity and specificity for the detection of c-kit-negative GIST cases may be of value, especially because some of these cases may also benefit from tyrosine kinase inhibitor therapy. 相似文献
Leukocyte adhesion deficiency is an autosomal recessive primary immunodeficiency that has been divided into three types: LAD1 (beta-2 integrin (CD18) family deficiency/defect), LAD2 (absence of fucosylated carbonhydrate ligands for selectins) and LAD3 (defective activation of all beta integrins). However, recently LAD4 has been described in cystic fibrosis patients, with a defect in integrin activation reported in monocytes. LAD-I is the most common type and prevalence of 1 in 1,000,000 live births. Clinical features of LAD patients are recurrent bacterial and fungal infections, omphalitis with delayed umbilical stump separation, significant leukocytosis especially neutrophilia during infection periods, impaired pus formation, and delayed traumatic or surgical wound healing. Flow cytometry is considered a useful tool for rapid diagnosis of the disease. The study of CD18 and CD11 (a, b, c) expression patterns in peripheral blood leukocytes helps to distinguish different phenotypes of LAD-I. In general, patients with ≥ 2% CD18 expression tend to have a less severe infection and often survive until adulthood, whereas < 2% CD18 expression often results in death in infancy. In this case report, three siblings, 10, 15, and 17 years old, diagnosed with leukocyte adhesion defect type 1 in adolescence age group, are presented.
IntroductionPassive antibody therapy has been used to immunize vulnerable people against infectious agents. In this study, we aim to investigate the efficacy of convalescent plasma (CP) in the treatment of severe and critically ill patients diagnosed with COVID-19.MethodThe data of severe or critically ill COVID-19 patients who received anti-SARS-CoV-2 antibody-containing CP along with the antiviral treatment (n = 888) and an age-gender, comorbidity, and other COVID-19 treatments matched severe or critically ill COVID-19 patients at 1:1 ratio (n = 888) were analyzed retrospectively.ResultsDuration in the intensive care unit (ICU), the rate of mechanical ventilation (MV) support and vasopressor support were lower in CP group compared with the control group (p = 0.001, p = 0.02, p = 0.001, respectively). The case fatality rate (CFR) was 24.7 % in the CP group, and it was 27.7 % in the control group. Administration of CP 20 days after the COVID-19 diagnosis or COVID-19 related symptoms were associated with a higher rate of MV support compared with the first 3 interval groups (≤5 days, 6?10 days, 11?15 days) (p=0.001).ConclusionCP therapy seems to be effective for a better course of COVID-19 in severe and critically ill patients. 相似文献
The aim of this study is to investigate postoperative complications, mortality rates, and to determine the factors affecting mortality on the patients receiving warfarin therapy preoperatively, as well as comparing the results obtained from emergency and elective surgeries. Surgical outcomes of 61 patients on long-term oral anticoagulation with warfarin who underwent surgery in our center were retrospectively reviewed over an 8-year period. Thirty-three (54.1%) patients were female, with a mean age of 53 years. Mitral valve replacement (62.3%) was the most frequent indication for chronic anticoagulation therapy. Twelve out of 61 (19.2%) patients underwent emergency surgery; 59 (96.7%) operations were classified as major surgery. We did not observe any thromboembolic events on patients receiving our bridging therapy protocol. Cardiopulmonary dysfunction (CPD; 19.7%) and hemorrhage (16.4%) were the most encountered postoperative complications. Presence of CPD, bleeding, endocarditis, and mortality were statistically significant for emergency surgeries when compared with the results obtained from elective surgeries. There were 5 (8.2%) deaths observed during follow-up. It was found that advanced age, prolonged duration of operations, and presence of CPD had a statistically significant effect on mortality (P < 0.05). The patients receiving oral anticoagulant had high postoperative complication and mortality rates. This case was more evident in emergency surgeries. It is recommendable that as mortality is more apparent in the patients who undergo emergency surgeries—being older, having long duration of operations as well as CPD. Therefore during the postoperative follow-up process, the patients should be closely monitored.Key words: Emergency, Postoperative complications, Morbidity, Mortality, WarfarinThromboembolism is a major global health concern contributing to more than 0.5 million deaths in Europe and up to 300,000 deaths in the United States each year.1 Versatile arrays of anticoagulant and/or anti-aggregant agents are available. They are used to treat and prevent thrombosis occurring as a result of venous stasis, valvular heart disease, prosthetic valves, atrial fibrillation, or myocardial infarction. After using these medications, patients who require elective or emergency surgery represent a specific population; moreover, they are prone to developing either excessive bleeding or thrombosis.The annual incidence of major bleeding as a result of oral anticoagulant (OAC) use is reported between 2 and 5%.2 Patients on OAC may require elective or sometimes emergency surgical or invasive procedures. There is no consensus on standard protocol to follow for those who require perioperative management.3In the current literature, there are limited numbers of studies regarding the discussions about the operations in general surgery patient population receiving warfarin treatments. In this retrospective study, our aim was to document the complications and outcomes of general surgical procedures implemented on patients receiving warfarin. Along with the comparison of the emergency and elective surgeries performed, we also aimed to determine the factors affecting mortality. 相似文献
Metastasis from prostate to thyroid gland is very uncommon. Here we report a 77-year-old man who was admitted to the hospital because of a nodular goiter. A fine-needle aspiration biopsy of the nodule showed metastatic prostatic adenocarcinoma. This is the second case of a metastatic prostate carcinoma to the thyroid gland. 相似文献
