Bronchiectasis is an abnormal dilation of the proximal and medium-sized bronchi (>2 mm in diameter) caused by weakening or destruction of the muscular and elastic components of the bronchial walls. Affected areas may show a variety of changes, including transmural inflammation, edema, scarring, and ulceration, among other findings. Distal lung parenchyma may also be damaged secondary to persistent microbial infection and frequent postobstructive pneumonia. Bronchiectasis can be congenital but is most often acquired.[9] Congenital bronchiectasis usually affects infants and children. These cases result from developmental arrest of the bronchial tree. Acquired forms occur in adults and older children and require an infectious insult, impairment of drainage, airway obstruction, and/or a defect in host defense. The tissue is also damaged in part by the host response of neutrophilic proteases, inflammatory cytokines, nitric oxide, and oxygen radicals. This results in damage to the muscular and elastic components of the bronchial wall. Additionally, peribronchial alveolar tissue may be damaged, resulting in diffuse peribronchial fibrosis.[12] The result is abnormal bronchial dilatation with bronchial wall destruction and transmural inflammation. The most important functional finding of altered airway anatomy is severely impaired clearance of secretions from the bronchial tree. Impaired clearance of secretions causes colonization and infection with pathogenic organisms, contributing to the purulent expectoration commonly observed in patients with bronchiectasis. The result is further bronchial damage and a vicious cycle of bronchial damage, bronchial dilation, impaired clearance of secretions, recurrent infection, and more bronchial damage
This is an example of a surgery to fix a femur (thigh bone) fracture utilizing an intramedullary nail. This is a minimally invasive way of fixing this surgical problem and allows for immediate range of motion and full weight-bearing.
The veins around your anus tend to stretch under pressure and may bulge or swell. Swollen veins (hemorrhoids) can develop from an increase in pressure in the lower rectum. Factors that might cause increased pressure include: Straining during bowel movements.
Expand Section. Pulmonary edema is often caused by congestive heart failure. When the heart is not able to pump efficiently, blood can back up into the veins that take blood through the lungs. As the pressure in these blood vessels increases, fluid is pushed into the air spaces (alveoli) in the lungs.
The objectives of hemodialysis are to extract toxic nitrogenous substances from the blood and to remove excess water. In hemodialysis, the blood, laden with toxins and nitrogenous wastes, is diverted from the patient to a machine, a dialyzer, in which the blood is cleansed and then returned to the patient. Diffusion, osmosis, and ultrafiltration are the principles on which hemodialysis is based.
The toxins and wastes in the blood are removed by diffusion—that is, they move from an area of higher concentration in the blood to an area of lower concentration in the dialysate. The dialysate is a solution made up of all the important electrolytes in their ideal extracellular concentrations.
The electrolyte level in the patient’s blood can be brought
under control by properly adjusting the dialysate bath. The semipermeable membrane impedes the diffusion of large molecules,
such as red blood cells and proteins.

Esophageal atresia is an abnormality, or birth defect, of the esophagus that occurs early in pregnancy, as the baby is developing. The esophagus forms in the first few months of fetal life as a long, hollow, continuous tube joining the mouth to the stomach. In newborns with this birth defect, formation of this continuous esophageal tube is interrupted. esophageal-artresia-2In most cases, two separate tubes are formed, an upper (proximal) tube connected to the mouth and a lower (distal) tube connected to the stomach. This seperated tubes are sealed off creating a pouch on either side; the gap between these pounches can be short or very long. Saliva can accumulate in the upper pouch as it cannot drain into the stomach.
What are diverticula? Diverticula are outpouchings that most commonly happen in the sigmoid colon of the large intestine. The presence of a diverticulum is defined as diverticulosis, whereas diverticulitis describes an inflamed diverticulum
💥Patellar Tendon Pain AKA “Jumper’s Knee”👇
💥If you have this, it’s likely because your patellar tendon was over-stressed beyond what it can currently handle (due to loads that are too high or lack of recovery).
🔑 Try 5 reps of 45 second holds
🔑 2 min of rest in between each rep
🔑 Keep your knees at roughly 60 deg angle
🔑 7/10 intensity
🔑Should not increase pain during or after exercise
📚A research article found that this protocol using a knee extension machine provided significant short term pain relief. Most people don’t have a knee extension machine at home, so you could try out a wall sit instead!
🔑It may be useful during the season of competition to decrease pain and allow the athlete to compete, if needed.

Pulmonary fibrosis is a condition in which the tissue deep in your lungs becomes scarred over time. This tissue gets thick and stiff. That makes it hard for you to catch your breath, and your blood may not get enough oxygen. Causes of pulmonary fibrosis include environmental pollutants, some medicines, some connective tissue diseases, and interstitial lung disease. Interstitial lung disease is the name for a large group of diseases that inflame or scar the lungs. In most cases, the cause cannot be found. This is called idiopathic pulmonary fibrosis
The most common position of the uterus is anteverted (cervix angles forward) and anteflexed (body is flexed forward). The position of the uterus in the adult is liable to considerable variation, depending chiefly on the condition of the bladder and rectum. Adnexa: In gynecology, the appendages of the uterus, namely the ovaries, the Fallopian tubes, and the ligaments that hold the uterus in place.
At first, grasping the needle is difficult because it will have a tendency to want to jump around. What can oftentimes help is to get hold of the thread with the left-hand forceps at a point 2 to 3 cm away from the needle. Dangle the needle until it just comes to rest on the surface. This will then allow you to use the angulated needle holder to grab the needle easily. Your needle is in a stable position if it is set up to 90 degrees to the axis of the tips of the forceps. You can make minor corrections by touching the needle with your left-hand forceps, or by partially relaxing your grip and nudging the needle tip against another firm object. You should hold the needle just behind its midpoint (If you hold it too near the tip, it will point downward. If you hold it too near the thread end, it will point upward.).
A peak flow meter is an inexpensive, portable, handheld device for those with asthma that is used to measure how well air moves out of your lungs. Measuring your peak flow using this meter is an important part of managing your asthma symptoms and preventing an asthma attack.
