Tetralogy of Fallot tetralogy of Fallot, a congenital heart defect which classically understood to involve four anatomical abnormalities wikipedia bronchiectasis bronchiectasis, a disease that causes localized, irreversible dilatation of part of the bronchial tree wikipedia mitral regurgitation mitral regurgitation, a valvular heart disease also known as mitral insufficiency, an abnormal leaking of blood through the mitral valve, from the left ventricle into the left atrium of the heart wikipedia eosinophilia Eosinophilia, a state of having a high concentration of eosinophils in the blood wikipedia Gaucher's disease Gaucher's disease, a most common of the lysosomal storage diseases wikipedia ventricular septal defect ventricular septal defect, a defect in the ventricular septum, a wall dividing the left and right ventricles of the heart wikipedia paroxysmal nocturnal hemoglobinuria Paroxysmal nocturnal haemoglobinuria (disorder characterized by intravascular hemolysis and hemoglobinuria) wikipedia Schistosoma mansoni Schistosoma mansoni (a species of trematode blood flukes of the family Schistosomatidae) wikipedia bronchopulmonary dysplasia Bronchopulmonary dysplasia, a chronic lung disorder that is most common among children who, a born prematurely, with low birthweights and who received prolonged mechanical ventilation to treat respiratory distress syndrome wikipedia Schistosoma japonicum Schistosoma japonicum (schistosomiasis caused by Schistosoma japonicum) wikipedia Wolman disease Wolman disease, a rare lipid storage disease that is usually fatal at a very young age wikipedia Multiple lentigines syndrome Leopard syndrome, a rare autosomal dominant, multisystem disease caused by a mutation in the protein tyrosine phosphatase, non-receptor type 11 gene wikipedia cor triatriatum Cor triatriatum, a congenital heart defect where the left atrium is subdivided wikipedia Fetal circulation, persistent Persistent fetal circulation, the condition caused by a failure in the systemic circulation and pulmonary circulation to convert from the antenatal circulation pattern to the "normal" pattern wikipedia Idiopathic pulmonary haemosiderosis Idiopathic pulmonary haemosiderosis, a condition affecting the lungs which results in bleeding from tiny alveolar capillaries wikipedia ostium primum atrial septal defect ostium primum atrial septal defect, a defect in the atrial septum at the level of the tricuspid and mitral valves wikipedia Idiopathic spinal scoliosis Idiopathic spinal scoliosis, the cause and medical condition with DiseasesDB code "6666" Obstructive sleep apnoea Obstructive sleep apnoea (a disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts) Coal worker pneumoconiosis Coal worker pneumoconiosis (a diffuse parenchymal lung disease caused by accumulation of inhaled carbon or coal dust) Altitude sickness, chronic Altitude sickness, chronic, the cause and medical concept with DiseasesDB code "29615" Diethylpropion Diethylpropion (a appetite depressant considered to produce less central nervous system disturbance than most drugs in this therapeutic category) Monocrotaline Monocrotaline (a pyrrolizidine alkaloid and a toxic plant constituent that poisons livestock and humans through the ingestion of contaminated grains and other foods) Indian familial childhood cirrhosis Indian familial childhood cirrhosis, the cause and medical concept with DiseasesDB code "32651" Pulmonary alveolar microlithiasis Pulmonary alveolar microlithiasis, the cause and medical concept with DiseasesDB code "33028" Pulmonary veno-occlusive disease Pulmonary veno-occlusive disease (pathological process resulting in the fibrous obstruction of the small- and medium-sized pulmonary veins and pulmonary hypertension) Pulmonary capillary hemangiomatosis Pulmonary capillary hemangiomatosis, the cause and medical concept with DiseasesDB code "34470" Pulmonary fibrosis Pulmonary fibrosis (a process in which normal lung tissues are progressively replaced by fibroblasts and collagen causing an irreversible loss of the ability to transfer oxygen into the bloodstream via pulmonary alveoli).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
