Facts about the brain: The brain contains around billion neurons. We have all our neurons when we are babies, but they aren’t yet connected as in an adult. Further, the brain is not fully myelinated until age years. This probably explains most developmental milestones, including those of Piaget. The brain has a great deal to do with our learning, thinking, mood, speech and behavior. See the end of this unit if you are philosophically inclined; many scientists are, and there are many different ideas. This leaves a lot of room for unrecognized syndromes and explanations for personality and interest variables. Skinner was a good person who was right about many things, but he tended to overlook the fact that we’re born different.

Cardiac Inflammatory Myofibroblastic Tumor: We report a series of 10 intracavitary polypoid myofibroblastic proliferations in children and young adults emphasizing gross, histologic, and clinical features. There were 6 females and 4 males, with a mean age of 10 years range 5 wk to 21 y. Symptoms included shortness of breath or dyspnea 3 , syncope 2 , chest pain 1 , transient ischemic attacks 1 , and fever with myalgias 1.
All tumors were surgical resections, except 1 tumor that resulted in sudden coronary death and that was diagnosed at autopsy, and 1 tumor that embolized into the coronary artery and was treated by cardiac transplant. Two tumors, present in the aortic and mitral valves, respectively, caused cardiac ischemia. The tumors were polypoid or filiform and histologically resembled inflammatory myofibroblastic tumors of extracardiac sites, with loose spindle cell growth with sparse inflammation.
Although there were frequent collagen bundles interspersed among the tumor cells, there were no large areas of dense fibrosis. Surface fibrin was present on the polypoid projections in 7 cases. Symptoms resulted from prolapse into coronary ostia or embolization, but no patient developed metastasis. Long-term follow-up in 2 patients demonstrated no evidence of disease or recurrence. Although metastatic potential was not identified, these tumors may result in serious symptoms, including myocardial infarct, syncope, and sudden death.
These cardiac myofibroblastic tumors are readily distinguished from other endocardial-based cardiac tumors, including papillary fibroelastoma and myxoma, which may present clinically in the same manner.
Coronary artery disease occurs from atherosclerosis, when arteries become narrow or hardened due to cholesterol plaque build-up. Further narrowing may occur from thrombi blood clots that form on the surfaces of plaques. Myocardial infarction occurs when a coronary artery is so severely blocked that there is a significant reduction or break in the blood supply, causing damage or death to a portion of the myocardium heart muscle. Depending on the extent of the heart muscle damage, the patient may experience significant disability or die as a result of myocardial infarction.
CBN is a helpful histological sign when dating myocardial infarctions. It is usually observed in the myocardium within the first hours of irreversible injury. Along with coagulative necrosis and colliquative myocytolysis, CBN in one of the 3 distinct structural patterns of myocardial .

European Cardiology – Volume 6 Issue 2; There are considerably fewer studies from living HCM patients with histopathological evaluation of surgical myectomy specimens or studies of endomyocardial biopsies from the right side of the interventricular septum. In this brief article, the relationship between histopathological features and clinical findings and outcome in patients with HCM will be discussed. Myocyte Disarray Myocyte disarray is characterised by regions of architectural disorganisation of hypertrophied myocytes and distinct nuclear changes.
Adjacent myocytes are arranged obliquely or perpendicularly to each other around foci of interstitial collagen plexiform fibrosis in a pinwheel or herringbone pattern. Myocyte disarray is not specific for HCM. This architectural disorganisation of the myocytes has been found, although to a lesser extent, in patients with dilated CM, alcoholic CM, various congenital heart diseases and cardiovascular diseases systemic hypertension, coronary artery disease and cor pulmonale and in normal hearts.
High incidences of SCD are associated with some troponin T mutations. Only myocardial disarray was found to correlate with left atrial volume index and diastolic dysfunction grade.

PY – Y1 – N2 – Infarct expansion is acute regional dilatation and thinning of the infarct zone. There are several possibilities for the mechanism of this alteration in cardiac shape: To determine the relative contributions of these cellular mechanisms of wall thinning and dilatation, detailed study of transverse histological sections of rat hearts with infarct expansion was performed 1, 2, and 3 days after coronary ligation. The number of cells across the wall was determined in six regions within, adjacent to, and remote from the infarct.
Cell counting was performed so that the total number of cells across the wall and the number of cells per unit length cell density across the wall were determined. The transmural cell count and the cell density were correlated with the wall thickness in each region. Myocyte cross-sectional areas and sarcomere lengths were also measured. The results from the infarct expansion hearts were compared with those of sham-operated control hearts that had been similarly analyzed.
To ensure that mechanisms identified in the rat were applicable to human infarct expansion, five hearts from patients who died within 3 days of infarction and two hearts from patients without coronary disease were studied histologically in a similar fashion.
Histopathological Changes and Clinical Implications in Patients with Hypertrophic Cardiomyopathy
It is an opportunity for us to reflect on the language and ideas that represented each year. So, take a stroll down memory lane to remember all of our past Word of the Year selections.

What Makes You Sick? On a blustery and frigid evening in early December, Professor Paul Ewald is huddled inside an auditorium with a group of 30 Amherst College students. Another suggests the seasonal variation in births of autistic children is a reason to suspect that an infection during pregnancy induces the disease. Like most students of science, I was taught that statistical associations are soft science: To back up his arguments, Ewald goes beyond curious associations such as those found for multiple sclerosis and autism, and argues his case from an evolutionary point of view: Diseases such as cancer, heart disease, and even schizophrenia and obsessive-compulsive disorder are too common to be caused primarily by bad genes, Ewald claims.
Natural selection, he says, should have weeded those genes out of the population long ago. Instead, some genes might merely be making people more susceptible to infectious organisms, which are the true culprits of chronic disease … But Ewald is more like a lone wolf than the leader of a pack. Any mammal would have a selective disadvantage if it tended to destroy itself when invaded by micro-organisms.
The increasing number of people who are color blind to various degrees can be pointed to as an example of the survival of defects, but this does not apply to our response to parasites:
A History: ’s Word of the Year
Open ppt At present the diagnosis of HCM is primarily made by the identification of one or more hypertrophied segments by a cardiac imaging modality. CMR cine imaging enables accurate and reproducible assessment of the extent and location of hypertrophy when considering a diagnosis of HCM. Extracellular matrix expansion is one of the histological hallmarks of the disease process, and can be detected using quantitative T1 and ECV mapping techniques.
Results demonstrate a good correlation with histological fibrosis quantification from specimens taken at the time of surgical myomectomy. Several groups have also shown that both native T1 value and ECV are elevated in subjects with a mutation known to cause HCM without sufficient phenotypic expression to diagnose the disease on current imaging criteria.
Cardiac Amyloidosis Cardiac amyloidosis is associated with progressive infiltration of the heart by extracellular amyloid protein resulting in hypertrophy of the left and right ventricles, interatrial septum and the atrioventricular valves.
