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 COPD

COPD, or chronic obstructive pulmonary disease, is a progressive inflammatory disease connecting the airways, lung parenchyma, and vasculature. It causes the damage and remodeling of the airways and lung tissue. Proper functioning of lungs is rejected continuously by COPD. Over a period of time, these changes result in more severe conditions such as pulmonary hypertension and right heart failure. The precise pathophysiology of COPD is unidentified. The inflammatory process is a driving aspect in the pathophysiology of COPD. Recent verification suggests that the inflammatory response results in a number of effects, including an arrival of inflammatory cells such as macrophages, neutrophils and lymphocytes. Thickened airways and structural changes such as increased smooth muscle and fibrosis may also be manifested. Cigarette smoking causes an inflammatory response in the lungs. This response does not cease with the removal of the stimulus, but progresses for an unlimited period of time

Pathophysiology of Typhoid Fever

Typhoid fever , also known as Typhoid , is a common worldwide illness, transmitted by the ingestion of food or water contaminated with the feces of an infected person, which contain the bacterium Salmonella enterica enterica, serovar Typhi. The bacteria then perforate through the intestinal wall and are phagocytosed by macrophages. The organism is a Gram-negative short bacillus that is motile due to its peritrichous flagella. The bacterium grows best at 37°C / 98.6°F – human body temperature. This fever received various names, such as gastric fever, abdominal typhus, infantile remittant fever, slow fever, nervous fever, pythogenic fever, etc. The name of "typhoid" was given by Louis in 1829, as a derivative from typhus . Pathophysiology of Typhoid Fever Transmission of Salmonella typhi can be transmitted through various ways, which is known with 5 M of the Food Fingers, Fomitus (vomiting), Fly, and through Faeces. Faeces and vomiting in patients with typhoid salmonel
