A small spontaneous pneumothorax may resolve without treatment; a pneumothorax arising as a result of lung disease or injury requires immediate treatment. Treatment may include insertion of a chest tube or aspiration of the free air in the chest cavity.

Whereas it is true that no operation has been profoundly affected by the advent of laparoscopy than cholecystectomy has, it is equally true that no procedure has been more instrumental in ushering in the laparoscopic age than laparoscopic cholecystectomy has. Laparoscopic cholecystectomy has rapidly become the procedure of choice for routine gallbladder removal and is currently the most commonly performed major abdominal procedure in Western countries.[1] A National Institutes of Health consensus statement in 1992 stated that laparoscopic cholecystectomy provides a safe and effective treatment for most patients with symptomatic gallstones and has become the treatment of choice for many patients.[2] This procedure has more or less ended attempts at noninvasive management of gallstones. The initial driving force behind the rapid development of laparoscopic cholecystectomy was patient demand. Prospective randomized trials were late and largely irrelevant because advantages were clear. Hence, laparoscopic cholecystectomy was introduced and gained acceptance not through organized and carefully conceived clinical trials but through acclamation. Laparoscopic cholecystectomy decreases postoperative pain, decreases the need for postoperative analgesia, shortens the hospital stay from 1 week to less than 24 hours, and returns the patient to full activity within 1 week (compared with 1 month after open cholecystectomy).[3, 4] Laparoscopic cholecystectomy also provides improved cosmesis and improved patient satisfaction as compared with open cholecystectomy. Although direct operating room and recovery room costs are higher for laparoscopic cholecystectomy, the shortened length of hospital stay leads to a net savings. More rapid return to normal activity may lead to indirect cost savings.[5] Not all such studies have demonstrated a cost savings, however. In fact, with the higher rate of cholecystectomy in the laparoscopic era, the costs in the United States of treating gallstone disease may actually have increased. Trials have shown that laparoscopic cholecystectomy patients in outpatient settings and those in inpatient settings recover equally well, indicating that a greater proportion of patients should be offered the outpatient modality

The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. The brain and spinal cord together make up the central nervous system (CNS).

Ventricular tachycardia is a type of heart rhythm disorder (arrhythmia) in which the lower chambers of your heart (ventricles) beat very quickly because of a problem in your heart's electrical system. In ventricular tachycardia, your heart may not be able to pump enough blood to your body and lungs because the chambers are beating so fast that they don't have time to properly fill. Ventricular tachycardia may be brief — lasting for just seconds and often not causing symptoms — or it can last for much longer, and you can develop symptoms such as dizziness or lightheadedness, or you can even pass out. This condition usually occurs in people with other heart conditions, such as coronary artery disease, cardiomyopathy and some types of valvular heart disease. Ventricular tachycardia may lead to a condition in which your lower heart chambers quiver (ventricular fibrillation), which may cause your heart to stop (sudden cardiac arrest) and lead to death if not treated immediately. Ventricular tachycardia can also cause your heart to stop, especially if the heart is beating very quickly, if it's lasting for a long period, and if you have an underlying heart condition.

Atrial flutter (AFL) is a type of abnormal heart rate, or arrhythmia. It occurs when the upper chambers of your heart beat too fast. When the chambers in the top of your heart (atria) beat faster than the bottom ones (ventricles), it complicates your heart rhythm

Menstruation is the time of month when the womb (uterus) sheds its lining and vaginal bleeding occurs. This is known as a menstrual period. Periods vary widely from woman to woman. Some periods are punctual, some are unpredictable. On average, a woman gets her period every 24 to 38 days. A period usually lasts about two to eight days. Irregular periods may require treatment. What Are Irregular Periods? You may have irregular periods if: The time between each period starts to change. You are losing more or less blood during a period than usual. The number of days that your period lasts varies significantly. There are different terms for different types of irregular periods: Irregular Menstrual Bleeding (IrregMB): Bleeding of more than 20 days in individual cycle lengths over a period of one year. Absent Menstrual Bleeding (amenorrhea): No bleeding in a 90-day period. Heavy Menstrual Bleeding (HMB): Excessive menstrual blood loss that interferes with the woman’s physical, emotional, social, and material quality of life and can occur alone or in combination with other symptoms. Heavy and Prolonged Menstrual Bleeding (HPMB): Less common than HMB. It is important to make a distinction from HMB given they may have different etiologies and respond to different therapies. Light Menstrual Bleeding: Based on patient complaint, rarely related to pathology.

Chronic pancreatitis is a long-standing inflammation of the pancreas that alters the organ's normal structure and functions. It can present as episodes of acute inflammation in a previously injured pancreas, or as chronic damage with persistent pain or malabsorption.

This is an introduction to ventilator settings like FIO2, PEEP, Flow rate,trigger,TV, and RR. I also discuss how these settings relate to CO2 and O2 control and to complications like oxygen toxicity and barotrauma with an emphasis on physiology.

Most people start smoking when they are in their teens and are addicted by the time they reach adulthood. Some have tried to quit but have returned to cigarettes because smoking is such a strong addiction. It is a habit that is very difficult to break. There are many different reasons why people smoke.

Inner Workings tells the story of the ceaseless pull of the human heart — even as it works against the very stoic realism of the brain.

Zinc deficiency symptoms include growth and development problems, hair loss, diarrhea, impotence, eye and skin conditions, and loss of appetite. Other symptoms may include weight loss, delayed wound healing, taste changes, and mental slowness.

Cardioversion takes minutes. The patient is sedated (for a few minutes) and then a shock is delivered. The heart nearly always goes back to regular sinus rhythm. ... Patients without prior ablation or heart surgery rarely develop non-right atrial flutter.

Angina results from a reduction in the oxygen supply/demand ratio. Therefore, in order to alleviate the pain, it is necessary to improve this ratio. This can be done either by increasing blood flow (which increases oxygen delivery or supply), or by decreasing oxygen demand (i.e., by decreasing myocardial oxygen consumption).

An enlarged spleen can be caused by infections, cirrhosis and other liver diseases, blood diseases characterized by abnormal blood cells, problems with the lymph system, or other conditions. Other causes of an enlarged spleen include: Inflammatory diseases such as sarcoidosis, lupus, and rheumatoid arthritis.

The protein inside red blood cells (a) that carries oxygen to cells and carbon dioxide to the lungs is hemoglobin (b). Hemoglobin is made up of four symmetrical subunits and four heme groups. Iron associated with the heme binds oxygen.
