Narouze The concept that headache might stem from the neck is an Diagnostic Criteria by the International old one. The term “cervicogenic headache” was coined in Classifications of Headache Disorders, 1983.

Osteoarthritis of the glenohumeral joint may be idiopathic or follow avascular necrosis 150mg fildena amex erectile dysfunction treatment in thailand, or radionecrosis following radiotherapy for carcinoma of the breast purchase fildena once a day erectile dysfunction pre diabetes. Infammatory Rheumatoid arthritis is more common than osteoarthritis in the shoulder joint cheap fildena 100 mg amex erectile dysfunction causes and solutions. Infective The patient presents with a painful, red, swollen joint with limited movement. There are systemic symptoms of malaise and fever and there is usually wasting of the muscle around the shoulder joint. Neoplastic Secondary deposits may occur in the upper end of the humerus, giving rise to pain. Check for a history of carcinoma of the bronchus, breast, thyroid, prostate or kidney. Cervical spondylosis often results in referred pain to the upper part of the shoulder. Irritation of the diaphragm may refer pain to the dermatome C4 at the shoulder tip. A history of chest problems should be sought if Pancoast’s tumour is suspected, especially if Horner’s syndrome is present. Carrying heavy loads on the shoulders over a prolonged period of time may also be responsible. Acquired Traumatic With dislocation of the shoulder, the patient supports the arm. With acromioclavicular dislocation, there will be a palpable lump at the site of dislocation. With fracture of the surgical neck of the humerus, there will be pain and tenderness, and inability to abduct the arm due to pain. With fractures of the clavicle, the patient supports the weight of the arm with the other hand. With frozen shoulder and osteoarthritis, there is limitation of active and passive movements. With osteoarthritis of the acromioclavicular joint, there is usually obvious prominence of the joint, with localised tenderness and a high painful arc. Neoplastic There may be little to fnd on examination or there may be a pathological fracture with pain, local tenderness and limitation of movement. With referred pain from the diaphragm, examine the abdomen for tenderness, guarding and rigidity. Note the winging of the scapula when the patient pushes the hand against a wall with the arm forward fexed to 90° (protraction of the scapula). There is a history of a fall on the outstretched hand followed by pain and swelling around the elbow. Fractures of the olecranon may result as a fall on the point of the elbow or by sudden contraction of the triceps. With myositis ossifcans, there will be a history of a supracondylar fracture or dislocation of the elbow. It may follow ill-advised physiotherapy with passive stretching of the joints after trauma or after surgery. Degenerative Osteoarthritis of the elbow may occur in heavy manual workers or following complicated fractures involving the joint. Osteochondritis dissecans may cause elbow pain and restrict movement because of a loose body in the joint. If there is gross disorganisation of the joint with deformity, the ulnar nerve may be involved and there may be symptoms of ulnar nerve palsy. Symptoms may present in the distribution of ulnar, median or posterior interosseous nerves. Other Olecranon bursitis results in painful or painless swelling over the olecranon. It is common in carpet layers and students (students rest their heads in their hands, while studying late into the night with their elbows resting on the desk). It affects tennis players and anyone whose job involves extending and twisting the forearm. The patient complains of pain and tenderness over the medial epicondyle and also of pain on hyperextending the fngers and wrists. Cubitus valgus may progressively stretch the ulnar nerve, with a slowly developing ulnar nerve palsy. The olecranon, medial epicondyle and lateral epicondyle preserve their normal relationship with one another in an equilateral triangle. With posterior dislocation at the elbow, the triangular relationship referred to above is lost. It is important to check the distal circulation and to assess for median and radial nerve palsies. With a fracture of the olecranon, there is swelling and tenderness directly over the olecranon. With damage to the medial epicondyle, it is important to test the integrity of the ulnar nerve. With myositis ossifcans, a calcifed mass occurs in front of the elbow joint and there will be limitation of fexion. With radial head fractures, the patient will be focally tender over the radial head and there will be lack of full extension. With osteochondritis dissecans, there may be restriction in movement, crepitus and locking of the joint due to a loose body. In longstanding arthritis, there will be a swollen, disrupted joint with deformity. Neurological Examine carefully in the distribution of the median, ulnar and radial nerve. Dislocations of the carpus are rare, the most common being dislocation of the lunate. Fracture of the scaphoid results from a fall on the 284 Joint DisorDers outstretched hand or a blow to the palm of the hand. Degenerative Osteoarthritis of the wrist is uncommon and usually a sequel to injury, e. The patient complains of pain on movement of the wrist and a weakness of the grip. Extensor ‘tenosynovitis crepitans’ follows excess activity and may affect all or only one of the extensor tendons. The patient usually complains of pain and tenderness over the dorsum of the wrist occurring with activity.

Clinical characteristics suggestive of adenocarcinoma of the breast rather than phyllodes tumor include skin invasion, ulcera- tion, or peau d’orange. Shiny thin skin is a characteris- tic of phyllodes tumors, but this is due to pressure necrosis rather than actual skin invasion. On mam- mography, phyllodes tumors are often smooth or lob- ulated, with well-defined margins. Ultrasound will oc- casionally demonstrate fluid-filled, elongated clefts within a solid mass, a classic sign of phyllodes tumors. Although many of these are present in the patient in this case, one aspect of her presentation that was not suggestive of phyllodes tumor was the presence of Figure 52.

Current recommendations for the treatment of ■ Mammogram locally advanced breast carcinoma are multimodal and include combinations of induction chemother- apy, surgery, and radiation therapy. Although pa- tients with inoperable disease (T4, N2, or N3) re- quire neoadjuvant chemotherapy or hormone therapy prior to local treatments, even those with operable disease at the time of diagnosis can benefit from induction chemotherapy if tumor shrinkage will not allow them to undergo breast-conserving surgery. This patient had a large unicentric tumor, and wished to preserve her breast if possible. Discussion A clinical response to initial anthracycline-based chemotherapy occurs in about 72% to 97% of cases. The majority of these are partial responses, with complete pathologic response seen in fewer than 15% of patients in most series. Characteristics pre- dictive of a good response to induction chemother- apy include high histologic grade, estrogen receptor negativity, and ductal rather than lobular histology, all of which were present in this patient. In studies of neoadjuvant therapy for large operable breast cancers, breast conservation is reported in 63% to 90% of cases.
