Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the heart valves snap shut. In cardiac auscultation, an examiner may use a stethoscope to listen for these unique and distinct sounds that provide important auditory data regarding the condition of the heart. In healthy adults, there are two normal heart sounds often described as a lub and a dub (or dup), that occur in sequence with each heartbeat. These are the first heart sound (S1) and second heart sound (S2), produced by the closing of the atrioventricular valves and semilunar valves, respectively. In addition to these normal sounds, a variety of other sounds may be present including heart murmurs, adventitious sounds, and gallop rhythms S3 and S4.

Traumatic penile injury can be due to multiple factors. Penile fracture, penile amputation, penetrating penile injuries, and penile soft tissue injuries are considered urologic emergencies and typically require surgical intervention. The goals of treatment for penile trauma are universal: preservation of penile length, erectile function, and maintenance of the ability to void while standing. Traumatic injury to the penis may concomitantly involve the urethra.[1, 2] Urethral injury and repair is beyond the scope of this article but details can be found in Urethral Trauma. Penile fracture Penile fracture is the traumatic rupture of the corpus cavernosum. Traumatic rupture of the penis is relatively uncommon and is considered a urologic emergency.[3] Sudden blunt trauma or abrupt lateral bending of the penis in an erect state can break the markedly thinned and stiff tunica albuginea, resulting in a fractured penis. One or both corpora may be involved, and concomitant injury to the penile urethra may occur. Urethral trauma is more common when both corpora cavernosa are injured.[4] Penile rupture can usually be diagnosed based solely on history and physical examination findings; however, in equivocal cases, diagnostic cavernosography or MRI should be performed. Concomitant urethral injury must be considered; therefore, preoperative retrograde urethrographic studies should generally be performed. See the images below.

Tension pneumothorax develops when a lung or chest wall injury is such that it allows air into the pleural space but not out of it (a one-way valve). As a result, air accumulates and compresses the lung, eventually shifting the mediastinum, compressing the contralateral lung, and increasing intrathoracic pressure enough to decrease venous return to the heart, causing shock. These effects can develop rapidly, particularly in patients undergoing positive pressure ventilation.

Renal artery stenosis is a narrowing of arteries that carry blood to one or both of the kidneys. Most often seen in older people with atherosclerosis (hardening of the arteries), renal artery stenosis can worsen over time and often leads to hypertension (high blood pressure) and kidney damage.

Keyhole surgery can be helpful for patients with brain, pituitary and skull base tumors. With cutting edge technology and a proven track record in keyhole and endonasal endoscopic approaches, we make surgery safer, less invasive and more effective.

St. John's wort (Hypericum perforatum) is an over-the-counter herbal supplement used for its antidepressant, anti-inflammatory, and wound-healing properties. Although it has been prescribed in Europe for mild to moderate depression, negative clinical trials and multiple reports of adverse drug interactions have raised concern about its use. St. John's wort induces various P450 isozymes (CYP 1A2, 2C19, 2C9, and 3A4) and P-glycoprotein systems. Drug interactions with the herbal product can lead to treatment failures with many medications, including hormonal contraceptives, antiretrovirals, immunosuppressive agents, narcotics, anticoagulants, and antifungals. There is also a risk for serotonin syndrome when St. John's wort is used in combination with other serotonergic antidepressants. The lack of strict regulation of herbal products that results in variable quality and content (unknown toxic ingredients or inactive ingredients) is also a concern.

Transcatheter aortic valve replacement (TAVR) has recently emerged as a therapeutic option for patients with severe aortic stenosis

If it is not removed, tooth decay will begin. The acids in plaque damage the enamel covering your teeth. It also creates holes in the tooth called cavities. Cavities usually do not hurt, unless they grow very large and affect nerves or cause a tooth fracture.

The pituitary gland is often portrayed as the "master gland" of the body. Such praise is justified in the sense that the anterior and posterior pituitary secrete a battery of hormones that collectively influence all cells and affect virtually all physiologic processes. The pituitary gland may be king, but the power behind the throne is clearly the hypothalamus. As alluded to in the last section, some of the neurons within the hypothalamus - neurosecretory neurons - secrete hormones that strictly control secretion of hormones from the anterior pituitary. The hypothalamic hormones are referred to as releasing hormones and inhibiting hormones, reflecting their influence on anterior pituitary hormones.

Nuclear medicine is a branch of medical imaging that uses small amounts of radioactive material to diagnose and determine the severity of or treat a variety of diseases, including many types of cancers, heart disease, gastrointestinal, endocrine, neurological disorders and other abnormalities within the body.
