OBJECTIVE: Varicose veins (VVs) are a common disorder of venous dilation and tortuosity, but the underlying mechanism is unclear. The functional integrity and phenotypic differences of VVs are also unclear. This study tested the hypothesis that phenotypic and functional differences exist between smooth muscle cells (SMCs) derived from VVs and normal veins. METHODS: SMCs were isolated from 28 samples of varicose great saphenous veins (VGSVs) and normal great saphenous (NGSVs) and cultured...

BACKGROUND: Lymphatic malformations (LMs) are low-flow congenital lesions that consist of cysts of varying size. Sclerotherapy with intralesional bleomycin and OK-432 has been reported to yield dramatically beneficial results for this disorder. However, inflammation-related symptoms are often seen after treatment with these sclerosing agents. On the other hand, polidocanol (POL) is reportedly associated with fewer allergic and inflammatory reactions. Up to now, however, very few reports have documented the use of POL microfoam for treatment of LMs...

OBJECTIVE: To evaluate central venous stenosis (CVS) etiologies and presentation within a vascular surgery practice. We evaluated endovascular treatment modalities and the patency rates of our interventions. METHODS: 5 year retrospective review of endovascular intervention for CVS. Patient demographics, medical comorbidities, and variables were collected including etiology, indwelling device, previous upper extremity (UE) deep venous thrombosis (DVT), long term UE indwelling device (defined as greater than 30 days), malignancy status, hypercoagulable disorders, history of radiation or mediastinal fibrosis or masses, and anticoagulation and/or antiplatelet therapy...

Activated protein C resistance (APCR) describes a hemostatic disorder characterized by a poor anticoagulant response to activated protein C (APC). This results in an increased risk of venous thrombosis, including deep vein thrombosis and pulmonary embolism. Protein C is a natural anticoagulant that is synthesized in the liver and is activated to APC via proteolysis. APC then degrades Factors Va and VIIIa. APCR describes the reduced inability of APC to cleave Factors Va and VIIIa, which therefore promotes increased thrombin generation and potentially leads to a prothrombotic state...

Venous thromboembolism, usually entailing deep vein thrombosis, pulmonary embolism, or both, is a complex and multifactorial disorder, in which a number of putative conditions interplay and finally contribute to propel the individual risk over a certain degree, so ultimately culminating in the development of venous occlusive disorders. Thrombophilia is commonly defined as a propensity to develop venous thromboembolism on the basis of an underlying hypercoagulable state attributable to inherited or acquired disorders of blood coagulation or fibrinolysis...

D-dimer has become one of the commonly requested coagulation tests, especially in the venous thromboembolism rule out setting. Appropriate D-dimer testing has significantly decreased the number of radiological investigations in this clinical scenario. D-dimer testing also plays an important role in the diagnostic process of the systemic coagulation disorders, especially disseminated intravascular coagulation in conjunction with other coagulation tests. However, widespread D-dimer testing without good understanding of the technical issues related to the test has recently caused some concerns...

BACKGROUND: Diabetes mellitus is a group of metabolic disorders that are caused by deficiency in insulin secretion or the decreased ability of insulin to act effectively on target tissues, particularly muscle, liver, and fat. As a result of insulin resistance in the target tissues, particularly in the adipocytes, free fatty acid flux is increased, leading to increased lipid synthesis in hepatocytes, which is responsible for diabetic dyslipidemia. OBJECTIVE: The objective of this study was to determine the prevalence and associated factors of dyslipidemia among diabetic patients in Durame General Hospital in Kembata Tembaro zone...

INTRODUCTION: Scoliosis is a complex three-dimensional spine deformity with the frontal plane deflexion (side-shift) of the series of vertebra from the midline and with torque deformity of vertebra, ribs, and the entire trunk towards the apex of curve. Chronic venous diseases present a group of pathological conditions caused by the increased venous pressure. The venous pressure may be increased due to genetics, ligament laxity, general obesity, injuries, and changes in biomechanics of spine and lower extremities, etc...

BACKGROUND: Ocular vascular occlusions following intraocular procedures are a rare complication. We report a case series of patients with retinal vascular occlusions or anterior ischemic optic neuropathy (AION) after anterior and posterior segment surgery and demonstrate possible risk factors. METHODS: Observational case series. RESULTS: In ten patients, vascular occlusions were observed within ten weeks after intraocular surgery: branch retinal arterial occlusion (BRAO) (n = 2), central retinal artery occlusion (CRAO) (n = 2), central retinal vein occlusion (CRVO) (n = 1), branch retinal vein occlusion (BRVO) (n = 1), anterior ischemic optic neuropathy (AION) (n = 3), and combined central artery and vein occlusion (n = 1)...

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare acquired disease characterized by clonal hematopoietic stem cell disorder, with increased mortality and morbidity. Venous thrombosis is the most common cause of mortality in PNH. The relationship between PNH and cerebrovascular disease is unclear; few cases are reported in the literature, most of them related to cerebral venous thrombosis; In PNH the involvement of intracranial and extracranial arterial sites is very rare. We report a case of a 49-year-old woman who has a medical history of diabetes mellitus, hypertension, and PNH and presented multiple lacunar strokes in a routine consultation with a hematologist...

The incidence of pediatric venous thromboembolism (VTE) has been increasing significantly in incidence over the past decade in part as a result of increased recognition of this serious disorder but more so due to the increased use of central venous catheters and other technological advancements involved in the care of ill children. Management of pediatric VTE is a complex undertaking considering that the vast majority of children who develop this complication have serious underlying medical disorders. Although the incidence is rising, compared to adults, this remains a relatively rare disorder and as such large scale clinical trials have not been completed rendering management decisions to be based upon extrapolation from adult data and the experience of the treating physician...

Background: Anemia is common in Congolese children, and inherited blood disorders may be a contributing cause. The presence of sickle cell variants, X-linked glucose-6-phosphate dehydrogenase (G6PD) deficiency and α-thalassemia, has been previously reported. G6PD A- deficiency is characterized by the co-inheritance of G6PD 376 and 202 variants and is common in sub-Saharan Africa.Objective: We aimed to measure the associations between inherited blood disorders and hemoglobin, ferritin, and soluble transferrin receptor (sTfR) concentrations in Congolese children...

Kimura's Disease (KD) is a rare chronic inflammatory disorder presenting as multiple painless solitary subcutaneous nodules, predominantly in the head and neck region and frequently associated with regional lymphadenopathy and/or salivary gland involvement. Because of painless nature and indolent course, there is usually a delay in the patient's presentation. KD may radiologically mimic other chronic inflammatory conditions like tuberculosis, vascular malformations and neoplasms. Clinical correlation and histological evaluation along with elevated peripheral eosinophil and serum IgE level are considered important for confirmatory diagnosis...

OBJECTIVE: Congenital prothrombin deficiency is one of the rarest clotting disorders. It is commonly subdivided in Type I defects or cases of 'true' prothrombin deficiency characterized by a concomitant decrease in FII activity and antigen and in Type II or dysprothrombinemias, in which FII activity is low but FII antigen is normal or near normal. A bleeding tendency, often a severe one, is the hallmark of the two-defects even though the bleeding is usually less severe in the Type 2 defects or dysprothrombinemias...

Holt-Oram syndrome is an autosomal dominant disorder, characterised by skeletal abnormalities of the upper limb associated with congenital heart defect, mainly atrial and ventricular septal defects. Skeletal defects exclusively affect the upper limbs in the preaxial radial ray distribution and are bilateral and asymmetrical. They range from clinodactyly, absent or digitalised thumb, hypoplastic or absent radii, and first metacarpal to hypoplastic ulna and carpal bone anomalies. Cardiac involvement ranges from asymptomatic conduction disturbances to multiple structural defects...

BACKGROUND: Acute heart failure (AHF) is a heterogeneous disorder, with most of the patients presenting with breathlessness along with varying degrees of peripheral edema. The presence of peripheral edema suggests that volume overload is the cause of decompensation leading to AHF, whereas breathlessness in the absence of edema may reflect a "vascular phenotype." This analysis investigated the characteristics, therapeutic response, and outcome of patients with AHF, with and without overt peripheral edema in the RELAX-AHF trial...

The autosomal dominant progeroid form of cutis laxa is a recently identified multiple congenital anomaly disorder characterized by thin, wrinkled skin, a progeroid appearance, intra-uterine growth retardation, postnatal growth restriction, psychomotor developmental delay, microcephaly, cataract, hypotonia and contractures. De novo heterozygous mutations in ALDH18A1 have been described in this condition. We present neuroimaging abnormalities in three patients. One patient had intracranial arterial and venous tortuosity, widened ventricular and extra-axial cerebrospinal fluid (CSF) spaces, wide perivascular spaces and increased T2 signal intensity in the cerebral white matter over time...

Status asthmaticus (SA) is a life-threatening disorder. Severe respiratory failure may require extracorporeal membrane oxygenation (ECMO). Previous reports have demonstrated utility of ECMO in SA in various patients with varying success. A 25-year-old man was admitted with status asthmatics and severe hypercapnic respiratory failure. Despite tailored ventilator therapies, such as pressure control ventilation and maximal pharmacological therapy, including general anaesthesia, the patient’s condition deteriorated rapidly...
