Abnormal cell proliferation and differentiation is responsible for the growth several different tumors.

Focal Nodulary Hyperplasia of the Liver Due to Congenital Portosystemic Shunt: A Rare Condition Mimicking Hepatocellulary Carcinoma.

Congenital portosystemic shunts are rare vascular malformations that lead to several complications including liver tumors, pulmonary hypertension, and metabolic encephalopathy. We describe a rare case of a 17-year-old girl with an extrahepatic portosystemic shunt presenting recurrent syncope episodes and a liver mass mimicking hepatocellulary carcinoma.

The successful non-invasive management of pulmonary thromboembolism in a child with acute lymphoblastic leukemia.

In childhood, pulmonary thromboembolism (PTE) is an uncommonbut potentially life-threatening disease. The greater numbers of venous thromboembolism (VTE) are complications of underlying risk factors such as malignancies, chemotherapy (L-asparaginase), and central venous catheter. We report a patient with acute lymphoblastic leukemia and PTE, who presented with near-syncope, and was successfully treated with low molecular weight heparin and calcium channel blockers.

Cementless total hip arthroplasty in developmental dysplasia of the hip with end stage osteoarthritis: 2-7 years' clinical results.

Between 2006 and 2011, 102 hips of 78 patients with end-stage osteoarthritis secondary to developmental dysplasia of the hip (DDH) underwent cementless total hip arthroplasty (THA). According to the Crowe's classification, 22 hips (21%) were type 1, 19 hips (18%) were type 2, 22 hips (21%) were type 3 and 39 hips (38%) were type 4 respectively. Functional and clinical analyses were performed by Harris Hip Scores (HHS).

Evaluation of cardiotoxicity by tissue Doppler imaging in childhood leukemia survivors treated with low-dose anthracycline.

Improvement in long-term survival in patients with acute childhood leukemia has led to the need for monitorization of chemotherapy-related morbidity and mortality. This study included 60 patients with acute lymphoblastic leukemia that were in remission for at least 2 years and 30 healthy controls. Systolic and diastolic function of myocardium was evaluated using conventional echocardiography and tissue Doppler imaging of the left ventricle, interventricular septum and right ventricle.

Outcomes for revision total knee replacement after unicompartmental knee replacement.

Objective: The aim of this retrospective, observational study was to describe the outcomes of total knee replacement (TKR) after failed Oxford phase 3 medial unicompartmental knee replacement (UKR).

Methods: The study included 24 revision TKRs (20 females, 4 males; mean age: 61 years) performed following failed aseptic UKR. Outcomes were assessed using the Knee Society Score (KSS).

Bradycardia related to ribavirin in four pediatric patients with Crimean-Congo hemorrhagic fever.

Crimean-Congo hemorrhagic fever (CCHF) is a potentially fatal fever due to infection with the CCHF virus, which belongs to the genus Nairovirus in the Bunyaviridae family and causes severe disease in humans, with reported mortality rates of 15-70% (Centers for Disease Control and Prevention 1983 ). Humans become infected through the bites of ticks, by contact with blood or tissue from viremic livestock, or by contact with a patient with CCHF during the acute phase of infection (Khan et al. 1997 ).

Native aortic valve endocarditis complicated by pseudoaneurysm of mitral-aortic intervalvular fibrosa.

Pseudoaneurysm of mitral-aortic intervalvular fibrosa (PA-MAIVF) is a rare complication of native aortic valve endocarditis. This region is a relatively avascular area and prone to infection during endocarditis and subsequent aneurysm formation. The rupture into the pericardial cavity and left atrium or aorta, systemic embolism, myocardial infarction secondary to left coronary compression, and sudden death are the reported complications.

Cemented versus Uncemented Oxford Unicompartmental Knee Arthroplasty: Is There a Difference?

Purpose. The use of uncemented unicompartmental knee prostheses has recently increased. However, few studies on the outcomes of uncemented unicompartmental knee prostheses have been performed.

Evaluation of cardiac functions and atrial electromechanical delay in children with adenotonsillar hypertrophy.

Deterioration of the right ventricular (RV) functions and the increase in the pulmonary arterial pressure (PAP) of children with moderate to severe adenotonsillar hypertrophy (ATH) have been well described. In addition to these complications, this study aimed to investigate the influence of ATH on the conduction system. The study investigated 46 patients with a diagnosis of ATH and 46 healthy control subjects.

Three-dimensional echocardiographic evaluation of a patient with double-orifice mitral valve, bicuspid aortic valve, and coarctation of aorta.

A 16-year-old male patient was diagnosed with bicuspid aortic valve and coarctation of aorta, and had a history of a subclavian patch plasty operation at 1 year of age. In addition, we detected double-orifice mitral valve (DOMV) at a routine evaluation and demonstrated by both two-dimensional and three-dimensional (3D) echocardiographic examinations. DOMV should be kept in mind in cases with left ventricular obstructive lesions and 3D echocardiography may provide a more detailed assessment of mitral valve and subvalvular apparatus.

The effect of recombinant human growth hormone therapy on left-ventricular chamber size and function in children with growth hormone deficiency.

This study was designed to assess the effect of recombinant human growth hormone (rhGH) therapy on left-ventricular (LV) chamber size and function in children with idiopathic isolated growth hormone deficiency (GHD) using conventional echocardiography and tissue Doppler imaging (TDI). Thirty patients (19 boys and 11 girls) with idiopathic isolated GHD were followed-up for 12 months. Mean age of patients was 11.

The assessment of time-dependent myocardial changes in infants with perinatal hypoxia.

Objective: The aim of the study was to assess myocardial damage in infants due to perinatal hypoxia.

Methods: The findings of 29 infants with perinatal hypoxia and 20 healthy infants were compared. Blood gas analysis, serum lactate, cardiac troponin I (cTnI), troponin T (cTnT), creatine kinase-MB (CK-MB) and B-type natriuretic peptide (BNP) were evaluated.

Pulmonary hypertension and reopening of the ductus arteriosus in an infant treated with diazoxide.

Diazoxide is the main therapeutic agent for persistent hyperinsulinemic hypoglycemia. Generally, it is tolerated well, but rarely it can cause severe life-threatening complications. We report a neonate who was treated with diazoxide for hyperinsulinemic hypoglycemia.

Anti-neutrophil cytoplasmic antibodies (ANCA) in serum and bronchoalveolar lavage fluids of cystic fibrosis patients and patients with idiopathic bronchiectasis.

We investigated the presence of anti-neutrophil cytoplasmic antibodies (ANCA) in the serum and bronchoalveolar lavage fluid (BALF) of 21 cystic fibrosis (CF), 7 idiopathic bronchiectasis (IBR), and 11 control children and the relation between ANCA and any bacteria grown in BALF. Six of the CFs, but none of the IBRs or controls had positive serum cytoplasmic or perinuclear-ANCA (c-ANCA, p-ANCA). Serum autoantibodies against bactericidal/permeability increasing protein (BPI-ANCA) were positive in 2 CFs, 1 IBR and 1 control.

All-transretinoic acid (ATRA) treatment-related pancarditis and severe pulmonary edema in a child with acute promyelocytic leukemia.

Use of all-transretinoic acid (ATRA) with other chemotherapeutic agents in the treatment of acute promyelocytic leukemia (APL) has been shown to cause the differentiation of abnormally granulated specific blast cells into mature granulocytes by acting on the t(15; 17) fusion gene product. The complete remission rate is increased and survival time is prolonged in APL patients who receive chemotherapy plus ATRA, whereas ATRA syndrome and other ATRA-related adverse effects including pseudo tumor cerebri, headache, severe bone pain, mucosal and skin dryness, hypercholesterolemia, and cheilitis may be observed especially during induction phase of the treatment. In this paper, we report a 9-year-old girl with APL who developed pancarditis while receiving the APL-93 treatment protocol.
