Esophageal cancer is a malignancy that develops in tissues of the hollow, muscular canal (esophagus) along which food and liquid travel from the throat to the stomach. Esophageal cancer usually originates in the inner layers of the lining of the esophagus and grows outward. In time, the tumor can obstruct the passage of food and liquid, making swallowing painful and difficult. Since most patients are not diagnosed until the late stages of the disease, esophageal cancer is associated with poor quality of life and low survival rates.

A hangman’s fracture is a bilateral fracture traversing the pars interarticularis of cervical vertebrae 2 (C2) with an associated traumatic subluxation of C2 on cervical vertebrae 3 (C3). It is the second most common fracture of the C2 vertebrae following a fracture of the odontoid process. In the acute setting, a rigid cervical collar should be immediately placed. The majority of Hangman’s fractures may be successfully treated with external orthosis alone. Vascular imaging should be performed in all C1 to C3 fractures. Management options vary depending on the specifics of the injury. This activity describes the presentation, evaluation, and management of hangman's fracture and highlights the interprofessional team's role in the care of affected patients.

Pemphigus - any of a group of diseases characterized by successive crops of large bullae (“water blisters”). Although rare, they are serious and require prompt treatment. The cause is unknown; they seem to occur only in adults and can occur in acute or chronic form. The term is often used alone to refer to pemphigus vulgaris.

Anal atresia is a congenital abnormality in which there is no opening at the end of the digestive tract, where the anus normally is. It is part of a wider spectrum of abnormalities involving the anus and last part of the bowel, the rectum. Anorectal malformations (ARMs) can range from mild abnormalities with only a thin membrane covering the anus to more severe abnormalities with the rectum ending high up in the belly. The rectum may be connected to the skin or other parts of the body, such as the bladder or the vagina, through a channel, called a fistula.

A ventricular septal defect happens during pregnancy if the wall that forms between the two ventricles does not fully develop, leaving a hole. A ventricular septal defect is one type of congenital heart defect. Congenital means present at birth. In a baby without a congenital heart defect, the right side of the heart pumps oxygen-poor blood from the heart to the lungs, and the left side of the heart pumps oxygen-rich blood to the rest of the body.

Dandy–Walker syndrome (DWS), is a rare congenital brain malformation in which the part joining the two hemispheres of the cerebellum (the cerebellar vermis) does not fully form, and the fourth ventricle and space behind the cerebellum (the posterior fossa) are enlarged with cerebrospinal fluid. Most of those affected develop hydrocephalus within the first year of life, which can present as increasing head size, vomiting, excessive sleepiness, irritability, downward deviation of the eyes and seizures

Restless legs syndrome (RLS) is a condition that causes an uncontrollable urge to move the legs, usually because of an uncomfortable sensation. It typically happens in the evening or nighttime hours when you're sitting or lying down. Moving eases the unpleasant feeling temporarily. Restless legs syndrome, also known as Willis-Ekbom disease, can begin at any age and generally worsens as you age. It can disrupt sleep, which interferes with daily activities.

Canavan disease is a gene-linked neurological disorder in which the brain degenerates into spongy tissue riddled with microscopic fluid-filled spaces. Canavan disease has been classified as one of a group of genetic disorders known as the leukodystrophies. Recent research has indicated that the cells in the brain responsible for making myelin sheaths, known as oligodendrocytes, cannot properly complete this critical developmental task.

Beta blockers, also known as beta-adrenergic blocking agents, are medications that reduce blood pressure. Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. Beta blockers cause the heart to beat more slowly and with less force, which lowers blood pressure. Beta blockers also help widen veins and arteries to improve blood flow.

B cells, also known as B lymphocytes, are a type of white blood cell of the lymphocyte subtype. They function in the humoral immunity component of the adaptive immune system. B cells produce antibody molecules which may be either secreted or inserted into the plasma membrane where they serve as a part of B-cell receptors. When a naïve or memory B cell is activated by an antigen, it proliferates and differentiates into an antibody-secreting effector cell, known as a plasmablast or plasma cell.

The connecting peptide, or C-peptide, is a short 31-amino-acid polypeptide that connects insulin's A-chain to its B-chain in the proinsulin molecule. In the context of diabetes or hypoglycemia, a measurement of C-peptide blood serum levels can be used to distinguish between different conditions with similar clinical features. In the insulin synthesis pathway, first preproinsulin is translocated into the endoplasmic reticulum of beta cells of the pancreas with an A-chain, a C-peptide, a B-chain, and a signal sequence. The signal sequence is cleaved from the N-terminus of the peptide by a signal peptidase, leaving proinsulin. After proinsulin is packaged into vesicles in the Golgi apparatus (beta-granules), the C-peptide is removed, leaving the A-chain and B-chain bound together by disulfide bonds, that constitute the insulin molecule. -

Primary adrenal insufficiency (AI), also called Addison's disease, is a rare condition where the adrenal glands do not work properly and cannot make enough cortisol (a “stress” hormone). Usually, production of aldosterone and androgens (the two other types of steroid hormones made by the adrenal glands) is also low. Secondary AI is the far more common type of AI. It results when the pituitary gland, a small gland near the brain, does not signal the adrenal glands to make cortisol. Production of aldosterone is normal in secondary AI. The adrenal glands do not get “adrenal fatigue” or lose function because of mental or physical stress. True AI is a rare health problem. Only an endocrinologist, an expert in hormones, should diagnose AI using standard tests.

A genetic disease caused by a mutation in the GLA gene, resulting in a deficiency of the enzyme alpha-galactosidase A, also known as ceramide trihexosidase. This enzyme is essential to the metabolism of a fat compound known as globotriaosylceramide. Without alpha-galactosidase A, this fatty substance accumulates in the walls of blood vessels, leading to narrowing and decreased blood flow to the tissues normally supplied by these vessels. Small vessels in the skin, kidneys, heart, and nervous system are preferentially affected, impairing function of these organs. Males with Fabry disease are more severely affected than females with it because the gene for Fabry disease is on the X chromosome. Males have only one X, whereas females have a second X and therefore some enzyme activity. Females with partial enzyme activity may not show any symptoms, or may have symptoms as severe as affected males. Diagnosis is made by determining the level of alpha-galactosidase A in blood plasma or through genetic testing.

The abnormal formation of the hip joint in which the ball at the top of the thighbone (the femoral head) is not stable within the socket (the acetabulum). The ligaments of the hip joint may also be loose and stretched.
The degree of instability or looseness varies. A baby born with this condition may have the ball of the hip loosely in the socket (subluxed) or the ball of the hip may be completely dislocated at birth.
Untreated, the condition may cause legs of different lengths and a "duck-like" walk and lead to pain on walking and early osteoarthritis. There is a familial tendency. It usually affects the left hip and is more common in girls than boys, in first-born children and in babies born in the breech position. It is more common in Native Americans than in whites and is rarely seen in African-American children.

Asystole is also known as flatline. It is a state of cardiac standstill with no cardiac output and no ventricular depolarization, as shown in the image below; it eventually occurs in all dying patients.
Pulseless electrical activity (PEA) is the term applied to a heterogeneous group of dysrhythmias unaccompanied by a detectable pulse. Bradyasystolic rhythms are slow rhythms; they can have a wide or narrow complex, with or without a pulse, and are often interspersed with periods of asystole. When discussing pulseless electrical activity, ventricular fibrillation (VF) and ventricular tachycardia (VT) are excluded.
