• A 40-year-old man presented to the emergency department with fatigue that had progressively worsened over a period of 3 months. He had recently emigrated from Mexico, where he had worked on a farm and eaten raw watercress. Examination revealed pallor of the oral mucosa. Laboratory studies showed severe anemia, an alkaline phosphatase level of 342 U per liter (reference range, 40 to 130), and an absolute eosinophil count of 1400 cells per cubic millimeter (reference range, 0 to 400). Ultrasonography of the abdomen revealed intrahepatic biliary ductal dilatation, and magnetic resonance cholangiopancreatography revealed a hilar stricture. Endoscopic retrograde cholangiopancreatography was then performed, and large flatworms were visualized emerging from the major duodenal papilla (see video). Worms were extracted and identified as the common liver fluke, Fasciola hepatica. Fasciola eggs in the feces of host animals (commonly sheep) contaminate fresh water; the larvae mature in snails and attach to vegetation. After the parasites are ingested by humans, they penetrate the intestine and invade the hepatobiliary tree. After treatment with blood transfusion and triclabendazole, the patient’s fatigue abated. Within 1 month, the patient’s anemia and eosinophilia resolved, and his elevated alkaline phosphatase level normalized.

• Video showing deep wrist laceration!
This was an accidental work related injury in a young man sustaining significant injury to most major structures in his wrist including vasculature, tendons, nerves and muscle.
9 tendons that pass through the wrist, 2 major nerves, muscles and major blood vessels required repair in a surgery lasting 8 hours!
Tendons are tissues that connect muscles to bone. When muscles contract, tendons pull on bones, causing parts of the body to move. Long tendons extend from muscles in the forearm and attach to the small bones of the fingers and thumb.
Most commonly, tendon injuries result from lacerations (cuts). A deep laceration to the forearm, hand or wrist can result in injury to the flexor tendons, which are quite close to the surface of the skin. Because tendons are under tension as they connect muscle to bone, the ends pull far apart when torn or cut, like a rubber band, making it impossible for the injured tendon to heal on its own.
Not all tendon injuries are due to lacerations. In some cases, the injury to a tendon can occur if the tendon end pulls away from bone, if the tendon ruptures due to wear, or if the tendon-muscle interface separates.
When a flexor tendon injury happens there can be inability to bend the fingers, thumb or wrist. It may also involve important nerves and blood vessels, resulting in numbness or inadequate blood supply.
Ruptured tendons are repaired by suturing the tendon stumps, and either tendon grafting or tendon transfer.
Ruptured nerves are sutured and repaired with a nerve graft.
Arteries and veins are mainly restored by primary repair, interposition grafting with autologous vein, or ligation. The ischemic limb is managed postoperatively with attention to reperfusion and compartment syndrome.
These types of injuries require significant amounts of occupational therapy to restore as much function to the hand as possible after the traumatic injury.

• The Process of Hearing
.
The process of #hearing involves sound waves creating mechanical motions that cause fluid in the #ear to move and waves and trigger nerve impulses that the brain interprets as sound.
.
The outer ear functions to funnel sound waves. The vibrations from these waves reach the middle ear and move the tympanic membrane also called the eardrum. This causes three bones called the auditory ossicles to also move. The bones make contact with a fluid-filled structure in the inner ear called the cochlea.
.
The mechanical movements of the auditory ossicles moved fluid inside the cochlea. Fluid waves move hair cells that line the cochlea. The movement of these cells activates nervous system receptors. Signals are carried through the vestibulocochlear nerve cranial nerve eight (CN VIII) to the temporal lobe of the brain where they're interpreted as sound.

• Laryngospasm notch!: Laryngospasm is a rare complication of procedural sedation, occurring in about 0.3% of ketamine sedations. The vocal cords spasm to a closed position. You’ll recognize it by stridor, which is the sound of upper airway obstruction. In severe cases, there may be lack of air movement and paradoxical abdominal breathing, where the chest drops and abdomen expands as the diaphragm tries to pull air in through a closed glottis. You can hear simulated stridor in this mannequin as the laryngospasm occurs. Let’s take a stepwise approach to management, starting with pinpoint pressure at the “laryngospasm notch”. It’s also called Larson’s point for the anesthesiologist who described it. Push at the base of the skull, between the mandibular condyle and the mastoid process, just inferior to the ear lobe. You can do this while simultaneously performing a jaw thrust. This may release the laryngospasm. It’s unclear how it works: it may be related to the painful stimulus, nerve stimulation, or just the jaw thrust. Step 2 is to provide positive pressure ventilation with a bag. Step 3 is to administer a paralytic like succinylcholine to relax the spasm. It’s a good idea to get the medication ready at the start of laryngospasm so you have it in case other maneuvers don’t work. (@med.guide)

• Ever heard of disc #herniation? This video #demonstrates what it is and how it happens.
-
A common cause of lower back and leg pain is a lumbar ruptured disc or herniated disc. Symptoms of a herniated disc may include dull or sharp pain, muscle spasm or cramping, sciatica, and leg weakness or loss of leg #function. Sneezing, coughing, or bending usually #intensify the #pain.

• Visible Intestinal Peristalsis in a Neonate!!
This male infant was delivered as the third trichorionic triamniotic triplet at 28 weeks of gestation by emergency cesarean section owing to growth arrest.
His birth weight was 1124 g, and the Apgar scores were 5 at 1 minute and 6 at 5 minutes. On the first day of life, he had bilious vomiting and abdominal distention with visible intestinal peristalsis, and he was unable to pass meconium. An abdominal radiograph showed distended bowel loops.
In such infants, this finding may be the result of any form of distal bowel obstruction, including meconium-related ileus, intestinal atresia, malrotation, and Hirschsprung’s disease. The administration of water-soluble contrast enemas can be not only diagnostic but also therapeutic.
However, surgical decompression is occasionally required. In this case, a diagnosis of meconium-related ileus was made. Repeated water-soluble contrast enemas were administered to clear the intestines of all plugs, and the vomiting and abdominal distention resolved. The patient was discharged on day 93 with full oral feeding.
