Occiput or cephalic — the baby's head is down, and the baby is facing the mother's abdomen. This position results in back pain and a prolonged labor. Transverse — the baby is lying crosswise in the uterus, side-to-side over the mother's pelvis, in a horizontal position rather than vertical.

Plantar warts are hard, grainy growths that usually appear on the heels or balls of your feet, areas that feel the most pressure. This pressure also may cause plantar warts to grow inward beneath a hard, thick layer of skin (callus). Plantar warts are caused by the human papillomavirus (HPV). The virus enters your body through tiny cuts, breaks or other weak spots on the bottom of your feet. Most plantar warts aren't a serious health concern and may not require treatment. But plantar warts can cause discomfort or pain. If self-care treatments for plantar warts don't work, you may want to see your doctor to have them removed.

People with serious comprehension difficulties have what is called Wernicke’s aphasia and: Often say many words that don’t make sense. May fail to realize they are saying the wrong words; for instance, they might call a fork a “gleeble.” May string together a series of meaningless words that sound like a sentence but don’t make sense. Have challenges because our dictionary of words is shelved in a similar region of the left hemisphere, near the area used for understanding words.

Alcoholic liver disease is a term that encompasses the liver manifestations of alcohol overconsumption, including fatty liver, alcoholic hepatitis, and chronic hepatitis with liver fibrosis or cirrhosis. It is the major cause of liver disease in Western countries.

Vascular dementia is a general term describing problems with reasoning, planning, judgment, memory and other thought processes caused by brain damage from impaired blood flow to your brain. You can develop vascular dementia after a stroke blocks an artery in your brain, but strokes don't always cause vascular dementia. Whether a stroke affects your thinking and reasoning depends on your stroke's severity and location. Vascular dementia also can result from other conditions that damage blood vessels and reduce circulation, depriving your brain of vital oxygen and nutrients

Laparoscopy in acute bowel obstruction following previous surgery is a difficult procedure and avoided by most of the surgeons due to the difficulty in obtaining pneumoperitoneum, port placement, lack of working space, adhesions and risk of bowel injury.
Here is a patient who had a previous laparotomy for trauma with a midline incision from xyphysternum to pubis; after unsuccessful conservative management he underwent a laparoscopy; a prior CT scan showed adhesions in the left side and a distal-mid small bowel obstruction. The pneumoperitoneum was obtained with the Visiport placed in the right lower quadrant; although the abdomen was grossly distended, under significant tension and distended loops of small bowel were occupying most the peritoneal cavity, with muscle relaxation there is usually enough space to perform a thorough inspection of the abdominal cavity. Port placement has to be done with special care as there is no room to push and usually a blunt trocar directed away from the bowel is employed in my practice. The collapsed loops of small bowel point quickly to the site of obstruction -- it is better to avoid manipulating the distended bowel as it is heavy, oedematous and prone to be lacerated with the instruments; once the pathology is identified, in this case the obstructive band, light packing is performed in order to expose the working space and protect the bowel from instruments like scissors or diathermy. In this case the band adhesion was slightly more difficult to separate from the bowel and required a combination of sharp and gentle blunt dissection.
Once the obstruction is release and the transit of contents is confirmed in the collapsed bowel the procedure is terminated. No abdominal drainage is usually necessary.

Your body needs bile, but if it has too much cholesterol in it, that makes gallstones more likely. It can also happen if your gallbladder can't empty properly. Pigment stones are more common in people with certain medical conditions, such as cirrhosis (a liver disease) or blood diseases such as sickle cell anemia.
