As a curious child, you might remember staring at an older relative's thick stockings at the blue, gnarled veins lying under the skin like bumpy snakes. Known as varicose veins, these blood vessels, which return blood from the legs to the heart, are actually a more superficial system. The real, working venous system for the legs lies deeper, says to Robert A. Weiss, MD, assistant professor of dermatology at the Johns Hopkins School of Medicine in Baltimore. This is good news, because it means that if the surface veins begin to clump up and bulge, they can be removed or destroyed without ruining circulation to the leg. The National Institutes of Health estimates that 60% of all men and women suffer from some form of vein disorder. A quarter of varicose vein sufferers are men, although Weiss notes that it is almost always women who seek help for spider veins.

Getting the right diagnosis often isnโt easy for psychiatric conditions. In our field, we donโt yet have biologic tests that can easily define one condition from another. If your blood pressure is 140 over 90, you have hypertension or high blood pressure. In mental health, we have to rely on a description of patterns or symptoms to makes diagnoses. This model is fraught with challenges. Without a clear biological model to work from, and given the complexity of the human brain, the field has settled upon dividing these descriptions of symptoms into syndromes.

Hyponatremia is defined as a serum sodium of less than 135 Meq per litre and occurs in upto 22 % of hospitalised patients. The causes of hyponatremia may be understood based on the pre-existing volume status of the patient which may either be hypovolemic, euvolemic or hypervolemic hyponatremia. This presentation discusses in detail, the causes of these underlying conditions. Also mentioned are the clinical features and management options and therapeutic sodium targets in patients with hyponatremia. Drugs such as demeclocycline and vaptans (Tolvaptan, Conivaptan) are also mentioned as management options which may be used on a case to case basis. Finally, the all important targets of sodium correction over 24 hours are also mentioned, along with a practical formula for calculation of sodium deficit which is explained with an example.

The biceps muscle is located in the front of your upper arm. It is attached to the bones of the shoulder and elbow by tendons โ strong cords of fibrous tissue that attach muscles to bones. Tears of the biceps tendon at the elbow are uncommon. They are most often caused by a sudden injury and tend to result in greater arm weakness than injuries to the biceps tendon at the shoulder. Once torn, the biceps tendon at the elbow will not grow back to the bone and heal. Other arm muscles make it possible to bend the elbow fairly well without the biceps tendon. However, they cannot fulfill all the functions of the elbow, especially the motion of rotating the forearm from palm down to palm up. This motion is called supination. To return arm strength to near normal levels, surgery to repair the torn tendon is usually recommended. However, nonsurgical treatment is a reasonable option for patients who may not require full arm function.

The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells. The basic function of the cell membrane is to protect the cell from its surroundings. It consists of the phospholipid bilayer with embedded proteins.
Eosinophilic granulomatosis with polyangiitis (EGPA)โor, as it was traditionally termed, Churg-Strauss syndromeโis a rare systemic necrotizing vasculitis that affects small-to-medium-sized vessels and is associated with severe asthma and blood and tissue eosinophilia. [1] Like granulomatosis with polyangiitis (Wegener granulomatosis), and the microscopic form of periarteritis (ie, microscopic polyangiitis), EGPA is an antineutrophil cytoplasmic antibody (ANCA)โassociated vasculitide. [2, 3, 4, 5] In 1951, Churg and Strauss first described the syndrome in 13 patients who had asthma, eosinophilia, granulomatous inflammation, necrotizing systemic vasculitis, and necrotizing glomerulonephritis. [3] In 1990, the American College of Rheumatology (ACR) proposed the following six criteria for the diagnosis of Churg-Strauss syndrome [6] : Asthma (wheezing, expiratory rhonchi) Eosinophilia of more than 10% in peripheral blood Paranasal sinusitis Pulmonary infiltrates (may be transient) Histological proof of vasculitis with extravascular eosinophils Mononeuritis multiplex or polyneuropathy

Parkinson disease (PD) is a common neurodegenerative condition. Typically beginning in the sixth or seventh decade of life, it is characterized by the unilateral onset of resting tremor in combination with varying degrees of rigidity and bradykinesia. PD was originally described by James Parkinson (1755-1824), a man of many talents and interests. Parkinson published works on chemistry, paleontology, and other diverse topics. Early in his career he was a social activist championing the rights of the disenfranchised and poor. His efforts in this area were enough to result in his arrest and appearance before the Privy Council in London on at least one occasion. In collaboration with his son, who was a surgeon, he also offered the first description in the English language of a ruptured appendix. His small but famous publication, "Essay on the Shaking Palsy," was published in 1817, seven years before his death. The clinical descriptions of 6 cases was remarkable in part because he never actually examined the people he described. Instead, he had simply observed these people on the streets of London.

Diabetic ketoacidosis is a serious complication of diabetes that occurs when your body produces high levels of blood acids called ketones. The condition develops when your body can't produce enough insulin. Insulin normally plays a key role in helping sugar (glucose) โ a major source of energy for your muscles and other tissues โ enter your cells. Without enough insulin, your body begins to break down fat as fuel. This process produces a buildup of acids in the bloodstream called ketones, eventually leading to diabetic ketoacidosis if untreated. If you have diabetes or you're at risk of diabetes, learn the warning signs of diabetic ketoacidosis โ and know when to seek emergency care.
