In-office testing
As part of clinical decision-making, a simple, minimally invasive, in-office procedure may be performed, the rotator cuff impingement test. A small amount of a local anesthetic and an injectable corticosteroid are injected into the subacromial space to block pain and to provide anti-inflammatory relief. If pain disappears and shoulder function remains good, no further testing is pursued. The test helps to confirm that the pain arises from the shoulder primarily rather than referred from the neck, heart, or gut. If pain is relieved, the test is considered positive for rotator-cuff impingement, of which tendinitis and bursitis are major causes. However, partial rotator-cuff tears may also demonstrate good pain relief, so a positive response cannot rule out a partial rotator-cuff tear. However, with demonstration of good, pain-free function, treatment will not change, so the test is useful in helping to avoid overtesting or unnecessary surgery. Classification
Tears of the rotator cuff tendon are described as partial or full thickness, and full thickness with complete detachment of the tendons from bone. Partial-thickness tears often appear as fraying of an intact tendon. Full-thickness tears are "through-and-through". These tears can be small pinpoint, larger buttonhole, or involve the majority of the tendon where it still remains substantially attached to the humeral head and thus maintains function. Full-thickness tears may also involve complete detachment of the tendon(s) from the humeral head and may result in significantly impaired shoulder motion and function.Shoulder pain is variable and may not be proportional to the size of the tear.
Retained antrum syndrome or retained gastric antrum syndrome is one of the rare postgastrectomy syndromes. It happens after Billroth II surgery and the mechanism involved is the inadequate removal of the distal antrum and pylorus during resection of the antrum and gastrojejunostomy.Lack of the usual acid-secreting gastric glands makes the antral segment continually exposed to the alkaline environment of the duodenum, which causes it to secrete excessive acid and be prone to form ulcers. == References ==
