Common Benign Pain Syndromes--Symptoms and Etiology:
1. Non-specific musculoskeletal pain: This is the most common cause of back pain. Patients present with lumbar area pain that does not radiate, is worse with activity, and improves with rest. There may or may not be a clear history of antecedent over use or increased activity. The pain is presumably caused by irritation of the paraspinal muscles, ligaments or vertebral body articulations. However, a precise etiology is difficulty to identify.
2. Radicular Symptoms: Often referred to as "sciatica," this is a pain syndrome caused by irritation of one of the nerve roots as it exits the spinal column. The root can become inflamed as a result of a compromised neuroforamina (e.g. bony osteophyte that limits size of the opening) or a herniated disc (the fibrosis tears, allowing the propulsus to squeeze out and push on the adjacent root). Sometimes, it's not precisely clear what has lead to the irritation. In any case, patient's report a burning/electric shock type pain that starts in the low back, traveling down the buttocks and along the back of the leg, radiating below the knee. The most commonly affected nerve roots are L5 and S1.
3. Spinal Stenosis: Pain starts in the low back and radiates down the buttocks bilaterally, continuing along the backs of both legs. Symptoms are usually worse with walking and improve when the patient bends forward. Patient's may describe that they relieve symptoms by leaning forward on their shopping carts when walking in a super market. This is caused by spinal stenosis, a narrowing of the central canal that holds the spinal cord. The limited amount of space puts pressure on the nerve roots when the patient walks, causing the symptoms (referred to as neurogenic claudication). Spinal stenosis can be congenital or develop over years as a result of djd of the spine. As opposed to true claudication (pain in calfs/lower legs due to arterial insufficiency), pain resolves very quickly when person stops walking and assumes upright position. Also, peripheral pulses should be normal.
4. Mixed symptoms: In some patients, more then one process may co-exist, causing elements of more then one symptom syndrome to co-exist.

The Knee Exam
Observation:
1. Make sure that both knees are fully exposed. The patient should be in either a gown or shorts. Rolled up pant legs do not provide good exposure!
2. Watch the patient walk. Do they limp or appear to be in pain? When standing, is there evidence of bowing (varus) or knock-kneed (valgus) deformity? There is a predilection for degenerative joint disease to affect the medical aspect of the knee, a common cause of bowing. Varus Knee Deformity, more marked on the left leg. 3. Make note of any scars or asymmetry. Chronic/progressive damage, as in degenerative joint disease, may lead to abnormal contours and appearance. Is there obvious swelling as would occur in an effusion? Redness suggesting inflammation? 4. Is there evidence of atrophy of the quadriceps, hamstring, or calf muscle groups? Knee problems/pain can limit the use of the affected leg, leading to wasting of the muscles.

While both legs have well developed musculature,
the left calf and hamstring are bulkier than the right. 5. Look at the external anatomy, noting structures above and below the knee itself: 1. Patella 2. Patellar tendon 3. Quadriceps/Hamstring/Calf muscles 4. Medial and lateral joint lines. 5. Femur and Tibia 6. Tibial tuberosity


Ballotment (helpful if the effusion is large) 1. Slightly flex the knee which is to be examined.
2. Place one hand on the supra-pateallar pouch, which is above the patella and communicates with the joint space. Gently push down and towards the patella, forcing any fluid to accumulate in the central part of the joint.
3. Gently push down on the patella with your thumb.
4. If there is a sizable effusion, the patella will feel as if it's floating and "bounce" back up when pushed down.

Maintaining sufficient blood flow to the gastric tube after a subtotal esophagectomy for esophageal cancer is crucial for decreasing the esophagogastric anastomotic leakage. After subtotal esophagectomy for esophageal cancer, to additionally revascularize the gastric tube using the splenic artery a...nd vein, external carotid artery, and internal jugular vein, the supercharge technique was performed in esophageal reconstruction patients. Operative results of these patients (supercharge group) were retrospectively compared with those of patients not receiving the technique (control group). Both operation time and operative blood loss in the supercharge group were significantly longer and larger than those of the control group. However, the incidence of anastomotic leakage was significantly lower in the supercharge group than in the control group, and a 30-day reduction in the mean postoperative hospital stay was achieved with the supercharge group. This practical supercharge technique could be a breakthrough less to reduce leakage during esophageal anastomosis.
