A Cesarean section (C-section) is surgery to deliver a baby. The baby is taken out through the mother's abdomen. In the United States, almost one in three women has their babies this way. Some C-sections are planned, but many are done when unexpected problems happen during delivery. Reasons for a C-section may include Health problems in the mother The mother carrying more than one baby The size or position of the baby The baby's health is in danger Labor is not moving along as it should
Part 2 of this educational video shows the dilatation and curettage (D&C) procedure, a gynecological operation used to sample or clear the uterine lining. It demonstrates the instruments and steps involved for clinicians and students. Procedure education only — not personal medical advice.
Breast cancer is a malignant tumor that develops from the cells of
the breast. It is the most common type of cancer among women in
the United States. It is most often curable when found early. The
normal breast consists of three main components: the lobules
(milk-producing glands), the ducts (thin tubes that connect the
lobules to the nipple) and the stroma (fatty tissue and ligaments
surrounding the ducts and lobules, blood vessels, and lymphatic
vessels). About 80% of breast cancers start in the ducts.

ectal exam is an internal examination of the rectum such as by a physician or other healthcare professional.
The digital rectal examination (DRE, Latin palpatio per anum or PPA) is a relatively simple procedure. The patient is placed in a position where the anus is accessible and relaxed (lying on the side, squatting on the examination table, bent over the examination table, etc). The physician inserts a gloved and lubricated finger into the rectum through the anus and palpates the insides.
The DRE is inadequate as a screening tool for colorectal cancer because it examines less than 10% of the colorectal mucosa; colonoscopy is preferred. However, it's an important part of a general examination, as many tumors or other diseases are made manifest in the distal part of the rectum.
This examination may be used: * for the diagnosis of rectal tumors and other forms of cancer; * in males, for the diagnosis of prostatic disorders, notably tumors and benign prostatic hyperplasia; * for the diagnosis of appendicitis or other examples of an acute abdomen (i.e. acute abdominal symptoms indicating a serious underlying disease); * for the estimation of the tonicity of the anal sphincter, which may be useful in case of fecal incontinence or neurologic diseases, including traumatic spinal cord injuries; * in females, for gynecological palpations of internal organs * for examination of the hardness and color of the feces (ie. in cases of constipation, and fecal impaction); * prior to a colonoscopy or proctoscopy. * to evaluate haemorrhoids
The DRE is frequently combined with an FOBT (fecal occult blood test), which may be useful for diagnosing the etiology of an anemia and/or confirming a gastrointestinal bleed.
Sometimes proctoscopy may also be part of a rectal examination.
Function and Anatomy: The hip is a ball and socket type joint, formed by the articulation of the head of the femur with the pelvis. Normal range of motion includes: abduction 45 degrees, adduction 20-30 degrees, flexion 135 degrees, extension 30 degrees, internal and external rotation. Hip pathology can cause symptoms anywhere around the joint, though frequently pain is anterior and radiates to the groin region. Additionally, pathology outside of the hip can be referred to this region. History and exam obviously help in making these distinctions.
Function and Anatomy:
Hinge type joint formed by the articulation of the Ulna and Radius (bones of the forearm), and Humerus (upper arm). Full extension is equal to 0 degrees, full flexion to ~ 150 degrees. Maximum supination (turning hand palm up so that it can hold a bowl of "soup") and pronation (palm down) are both 90 degrees
Shoulder Exam
I think that the most daunting aspect of the shoulder exam is appreciating the functional anatomy of this incredibly mobile joint. The primary benefit of the ball and socket arrangement is that it allows the hand to be positioned precisely in space, maximizing our ability to function. In terms of functionality, the shoulder might be best described as having a golf ball-on-a-tee design.
Location Of The Muscle Groups Is Approximated In The Pictures Above.
Start by looking at the normal (or more normal) side. Note any scars, obvious asymmetry, discoloration, swelling, or muscle asymmetry.
Palpation
Gently palpate around the shoulder, touching each of the landmarks noted above. Make note of pain.
Normal Heart Sounds With the aid of a stethoscope you can hear the characteristic sounds of the normal heartbeat, typically described as a "lub-dub." These sounds are produced by the closure of the heart valves. The first heart sound or "lub" results from closure of the tricuspid and mitral valves. It is a rather low-pitched and a relatively long sound which, as indicated in, represents the beginning of ventricular systole. The second heart sound, or "dub," marks the beginning of ventricular diastole. It is produced by closure of the aortic and pulmonary (pulmonic) semilunar vanes when the intraventricular pressure begins to fall. This "dub" sound is typically heard as a sharp snap because the semilunar valves tend to close much more rapidly than the AV valves. Because diastole occupies more time than systole, a brief pause occurs after the second heart sound when the heart is beating at a normal rate. Therefore, the pattern that one hears is one of: "lub-dub" pause, "lub-dub" pause, and so on. Sometimes, especially in young normal individuals, a third heart sound can be heard. This sound is produced by the very rapid influx of blood into the partially filled ventricle. It is typically very faint and as such difficult to hear.
Anoscopy performed with the patient in the jackknife position is demonstrated in this educational video. Anoscopy uses a short, lighted instrument to examine the anal canal and lower rectum. A clinical-skills resource for students of colorectal examination. Educational only — not medical advice.
