granulomatous amebic encephalitis |
Granulomatous amebic encephalitis is a life-threatening infection of the brain caused by the free-living amoebae Acanthamoeba spp., Balamuthia mandrillaris and Sappinia pedata. Acanthamoeba species, are commonly found in lakes, swimming pools, tap water, and heating and air conditioning units. The disease affects immunocompromised peple and is very serious. Symptoms include mental status changes, loss of coordination, fever, muscular weakness or partial paralysis affecting one side of the body, double vision, sensitivity to light and other neurologic problems. The diagnosis is difficult and is often made at advanced stages. Tests useful in the diagnosis include brain scans, biopsies, or spinal taps and in disseminated disease, biopsy of the involved sites and testing by the laboratory experts. Early diagnosis is important for the prognosis. No single drug is effective; hence multiple antibiotics are needed for successful treatment. A combination of surgical and medical interventions involving multiple specialty experts is required to prevent death and morbidity in survivors. |

Hypoparathyroidism is is an endocrine disorder in which the parathyroid glands in the neck do not produce enough parathyroid hormone (PTH). Common signs and symptoms includeabdominal pain, brittle nails, cataracts, dry hair and skin,muscle cramps,tetany, pain in the face, legs, and feet, seizures, tingling sensation,and weakened tooth enamel (in children). It may be caused byinjury to the parathyroid glands (e.g., during surgery). Other causes, include low blood magnesium levels, a side effect of radioactive iodine treatment for hyperthyroidism, metabolic alkalosis, DiGeorge syndrome, and type I polyglandular autoimmune syndrome. The goal of treatment is to restore the calcium and mineral balance in the body. |

protein S deficiency |
Protein S deficiency is a disorder that causes abnormal blood clotting. When someone bleeds, the blood begins a complicated series of rapid chemical reactions involving proteins called blood coagulation factors to stop the bleeding. Other proteins in the blood, such as protein S, usually regulate these chemical reactions to prevent excessive clotting. When protein S is missing (deficient), clotting may not be regulatednormally and affected individuals havean increased risk of forming a blood clot called a thrombosis. People at risk to haveprotein S deficiencyare those with an individual or family history of multiple blood clots in the veins. Treatment may include taking medication known as blood thinners to decrease the chance of developing a blood clot. |

partial duplication of the short arm of chromosome 6 |
Chromosome 6p duplication is a chromosome abnormality that occurs when there is an extra copy of genetic material on the short arm (p) of chromosome 6. The severity of the condition and the signs and symptoms depend on the size and location of the duplication and which genes are involved. Features that often occur in people with chromosome 6p duplication include developmental delay, intellectual disability, behavioral problems and distinctive facial features. This condition can occur sporadically or be inherited from aparent who is either mildy affected (has the deletion) or carries a balanced translocation. Treatment is based on the signs and symptoms present in each person. |

sickle cell-beta-thalassemia disease syndrome |
Sickle beta thalassemia is an inherited condition that affects hemoglobin, the protein in red blood cells that carries oxygen to different parts of the body.It is a type of sickle cell disease. Affected people havea differentchange (mutation) in each copy of their HBB gene: onethat causes red blood cells to form a 'sickle' or crescent shape and a second that is associated with beta thalassemia, a blood disorder that reduces the production of hemoglobin. Depending on the beta thalassemia mutation, people may have no normal hemoglobin (called sickle beta zero thalassemia) or a reduced amount of normal hemoglobin (called sickle beta plus thalassemia). The presence of sickle-shaped red blood cells, which often breakdown prematurely and can get stuck in blood vessels, combined with the reduction or absence of mature redblood cells leadsto the many signs and symptoms of sickle beta thalassemia. Features, which may include anemia (low levels of red blood cells), repeated infections, and frequent episodes of pain, generally develop in early childhood and vary in severity depending on the amount of normal hemoglobin made. Sickle beta thalassemia is inherited in an autosomal recessive manner. Treatment is supportive and depends on the signs and symptoms present in each person. |

It is frequently associated with an initial precipitating event, such as febrile seizures, hypoxia, intracranial infection or head trauma, most often occurring in the first five years of life, followed by a latent period without seizures. Typical seizures consist of a characteristic aura that is frequently a rising epigastric sensation associated with emotional disturbances, illusions, and autonomic symptoms (widened pupils, palpitations), progressive impairment of consciousness, oro-alimentary automatisms (lip smacking, chewing, licking, tooth grinding), behavioral arrest, head deviation, dystonic postures, hand and verbal automatisms. Seizures are followed by postictal dysfunction. Initially, seizures are easily controlled with antiepileptic drugs, later they frequently become refractory and associated with progressive behavioral changes and memory deficits. |

alcoholic ketoacidosis |
An acute disease characterized by severe ketoacidosis in the absence of diabetes mellitus and occuring in individuals with a history of prolonged excessive alcohol consumption. Disease manifestations include nausea, intractable vomiting, and abdominal pain. When treated, AKA resolves rapidly and completely with no apparent sequelae. |

Mac-Leod-Swyer-James-Syndrome |
A rare lung condidtion characterized by often predominantly unilateral lung hyperlucency and air trapping. The condition is a post-infectious form of bronchiolitis obliterans and typically follows a viral respiratory infection in infancy and childhood. Adenovirus infection is considered the most usual epidemiology. In SJS, the involved lung or portion of the lung does not grow normally and is slightly smaller than the opposite lung: in particular, peripheral branches of the pulmonary vessels do not develop, and vasculature is arreseted at the stage at which the infection occurred. Patients respond well to management with bronchodilators, even though this is not primarily a bronchial abnormality. |

retained medullary cord |
A rare closed dysraphism with terminal stalk characterized by persistant rudimentary spinal cord below conus. It contains non-functional neural tissue and is typically isolated. The diagnostic is suggested by attenuated conus without fat, further confirmed by pathological analysis (glioneuronal core with ependyma-lined lumen, nerve roots, and dorsal root ganglia). Differential diagnostic with intraoperative neurophysiological monitoring is mandatory as neuroimaging fails to distinguish it from functional conus. |
