Conclusion: Patent processus vaginalis should always be kept in mind in evaluating patient with perforated appendicitis who develops acute scrotum, regardless the age of patients. We report a rare case of an adult patient who developed scrotal abscess as a complication of a perforated appendicitis. Keyword: patent processus vaginalis, perforated appendicitis, scrotal abscess, ultrasonography Background Patent processus vaginalis (PPV) may change the natural history of appendicitis, one of…

Pulmonary Hypertension is a condition that complicates virtually every level of patient care; from basic prehospital care to tertiary care in a hospital. Perhaps reason it remains as such a nuisance to health care providers is the fact that it is has a very gradual progression from chronic ailment to serious health problem sometimes taking a long time to develop more serious health problems. Pulmonary Hypertension in the most basic and literal sense is defined as increased blood pressure…

One candidate biological system that may function to optimize social connections is parasympathetic activity, often conceptualized as the functioning of the vagus nerve and measured as respiratory sinus arrhythmia (RSA) or high-frequency heart rate variability (HF-HRV) at rest. The longest autonomic nerve in the human body, the vagus contributes to the innervation of the viscera, including the heart. Measures of cardiac vagal function like RSA have been used as a proxy for the parasympathetic…

As a mammal, kangaroo has a respiratory system similar to human respiratory system. They breathe though their nose and mouth. They have a diaphragm and a pair of lungs which are sealed in pleural membranes inside the chest cavity and protected by ribcage. The lowering of diaphragm and expanding of ribcage create a negative pressure in lungs to draw air into lungs, so-called inspiration. Their breathing is linked to their hopping. During locomotion, the diaphragm move up to push out air of…

All tissues in the body rely on oxygen (O2) that is transported in the blood to meet their metabolic needs. O2 is carried in two ways: dissolved or bound to hemoglobin. About 98% of oxygen is transported bound to hemoglobin. And the remaining 2% is carried in the dissolved state. Dissolved oxygen is the only form that diffuses across the cell membranes and produces a partial pressure (PO2) which drives diffusion. The transport of O2 involves the transfer from the alveoli to the pulmonary…

Cardiopulmonary resuscitation (CPR) is a lifesaving technique that is useful in many emergency situations; including heart attack or near drowning, in which someone's breathing or heartbeat has stopped. When the heart stops, the lack of oxygenated blood can cause brain damage in only a few minutes. A person may die within 10 minutes. To be better prepared before giving CPR, it’s better to take a First-Aid class. Taking a First-Aid course will properly teach you the steps and health risks that…

The topic of the article that I found online is the cardiovascular anatomy and physiology, which revolves around the heart. Gross anatomy, diseases, and photos are shown for readers to learn more about as to how the system that is in charge of pumping thousands of gallons of blood each day allows bodily function and movement. Many diagrams are included to show what each structure looks like, as well as how it works with other structures or substances within the body. I chose this specific…

Congestive heart failure is a disease in which the heart is unable to adequately pump the blood of the heart to the rest of the body, and thus the blood is not circulated properly. The blood that is not circulated can do a backward overflow into the lungs, and create problems breathing. Congestive heart failure thus can create edema, shortness of breath, irregular heartbeat, coughing, and fatigue. The problem that a lot of the elderly congestive heart failure patients deal with is being…

Hemophilia is a medical condition that makes the blood in the bodies system to not be able to clot, casing the injury to bleed severely. The major effects of hemophilia are bleeding in the brain, bleeding in the joints, and excessive bleeding. Internal bleeding in the brain is a very serious difficulty in hemophilia. It can happen by the smallest bump on the head or something more serious. Bleeding in the joints can occur without obvious injury. The extent of the bleeding deepens on how severe…

Strongyloides stercoralis is the nematode parasite (round worm) , found in north America , Montreal ,Chicago and the various area in the world. The worm length is 2mm and cusses Strongyloidesis disease .The parasite have tow complex life cycle , free life cycle in the soil (without host) and parasite infection inside the host . The worm capable to causes the autoinfection and reproduction within the host . larva found in the stool from intestine , adult worm free livening . The parasite male…
