Pathophysiology of Dengue Hemorrhagic Fever

Dengue hemorrhagic fever

Dengue hemorrhagic fever is a severe, potentially deadly infection spread by certain species of mosquitoes (Aedes aegypti).

Pathophysiology of Dengue Hemorrhagic Fever

Dengue viruses enter the body through the bite of aedes aegypti mosquito and then react with the antibody and virus-antibody complexes formed, the circulation will activate the complement system.

Dengue viruses enter the body through mosquito bites and infection first causes dengue fever. Body reaction is a reaction commonly seen in infection by the virus. A very different reaction would appear, if someone gets recurrent infections with different dengue virus type. And Dengue hemorrhagic fever can occur when a person after infection the first time, get recurrent infections other dengue virus. Re-infection will cause an anamnestic antibody response, causing the concentration of antigen-antibody complex is high.

Hematemesis Melena Pathophysiology

A history of dyspepsia, peptic ulcer is the initial allegations. So is a history of recurrent vomiting who initially did not bleed, excessive alcohol consumption leads to the suspicion of gastritis and peptic ulcer disease. A history of recurrent vomiting who initially did not bleed more towards Mallory-Weiss. Excessive alcohol consumption leads to allegations of gastritis (30-40%), peptic ulcer disease (30-40%), or sometimes varicose veins. Weight reduction leads to the suspicion of malignancy. Heavy bleeding accompanied by a clot and refractory shock treatment increases the likelihood of varicose veins. A history of previous abdominal aortic surgery increases the likelihood of fistula aortoenterik. At the young age of patients with a history of upper gastrointestinal bleeding brief repeated (often accompanied by hemodynamic collapse) and a normal endoscopy, should be considered Dieulafoy lesion (a submucosal artery, usually near the heart, which can cause intermittent gastrointestina...

Pathophysiology of Congestive Heart Failure (CHF)

Congestive Heart Failure (CHF) Congestive heart failure, or heart failure, is a condition in which the heart is unable to adequately pump blood throughout the body and/or unable to prevent blood from "backing up" into the lungs. In most cases, heart failure is a process that occurs over time, when an underlying condition damages the heart or makes it work too hard, weakening the organ. Heart failure is characterized by shortness of breath (dyspnea) and abnormal fluid retention, which usually results in swelling (edema) in the feet and legs. Pathophysiology of Congestive Heart Failure (CHF) Heart failure occurs, the body undergoes some adaptation, both in heart and systemically. If the stroke volume of both ventricles is reduced, because of pressure contractility, or afterload are greatly increased, the volume and pressure at the end of diastolic heart in two space will increase. This will increase the end diastolic myocardial fiber length, causing systolic time beco...

Pathophysiology of Meningitis

Pathophysiology of Meningitis Predisposing factors include upper airway infection, otitis media, mastoiditis, sickle cell anemia and other hemoglobinopatis, a new neurosurgical procedure, head trauma and immunological effects. Venous channels through the posterior nasopharynx, middle ear and mastoid tract to the brain and the veins near the channel meningen; all of these links that support the growth of bacteria. Organisms enter the bloodstream and cause an inflammatory reaction in the meningen and under the cortex, which can cause thrombus and decreased cerebral blood flow. Cerebral tissue due to impaired metabolism meningen exudate, vasculitis and hypoperfusion. Purulent exudate may spread to the base of the brain and spinal cord. Inflammation also spread to the wall membrane of the cerebral ventricles. Bacterial meningitis associated with intracranial physiological changes, which consisted of increased permeability of the blood, the defense area of the brain, cerebral edema an...
