New imaging of the anterior male urethra.

Retrograde urethrography is the method commonly employed in the detection of anterior male urethra pathology. Ultrasonography and magnetic resonance imaging have been proposed recently as new methods that can replace conventional radiography. Normal urethral anatomy can be easily studied after saline distention of the urethra, which creates high contrast relative to adjacent structures such as mucosa and corpus spongiosum. Sonourethrography with high-frequency probes has a high spatial resolution and has proved to be sensitive, specific, and accurate in the diagnosis of anterior urethral pathologies such as strictures, syringocele, tumors, and trauma. It has a major role in the selection of therapy in patients with bulbar strictures. Magnetic resonance imaging with a surface coil with a small field of view can detect penile and bulbar stenoses and tumor extension. After contrast administration, the activity of the inflammatory process in the spongiosum can be assessed and used to modify the urethroplasty technique. The clinical use of the new imaging modalities in the male anterior urethra is limited despite their demonstrated accuracy in diagnosis and presurgical staging of different diseases.

Isolated tenosynovitis associated with psoriasis triggered by physical injury.

A 60-year-old man who had been suffering from psoriasis for 20 years developed finger dactylitis and inflammatory swelling with pitting edema over the dorsum of the hand one week after a contusive trauma to the left hand. These were not followed by any other clinical manifestations of PsA.

Magnetic resonance imaging in the diagnosis of PMR.

The cause of musculoskeletal symptoms in polymyalgia rheumatica (PMR) is not clearly defined because joint synovitis may only partially explain the diffuse discomfort. MRI imaging of the shoulders, hip and extremities of patients with PMR has been analyzed. MRI showed that subacromial and subdeltoid bursitis of the shoulders and iliopectineal bursitis and hip synovitis are the predominant and most frequently observed lesions in active PMR. The inflammation of the bursae associated with glenohumeral synovitis, bicipital tenosynovitis and hip synovitis may explain the diffuse discomfort and morning stiffness.

Distal extremity swelling with pitting edema in psoriatic arthritis: a case-control study.

OBJECTIVE: To evaluate the frequency and the clinical characteristics of distal extremity swelling with pitting edema in patients with psoriatic arthritis (PsA). METHODS: This was a case-control study of consecutive outpatients with PsA (old and new diagnosis) observed over a 3-month period in three secondary referral centers in Italy. As controls we used the two consecutive rheumatic outpatients, excluding those with spondylarthropathies, observed after a PsA patient. The demographic and clinical features were assessed by clinical examination and review of the medical records. RESULTS: A total of 183 patients with PsA and 366 controls were evaluated. Distal extremity swelling with pitting edema was recorded in 39/183 (21%) PsA patients and in 18/366 (4.9%) controls (p < 0.0001). In 8/39 (20%) patients this feature presented as a first, isolated manifestation of PsA, and in 8 others it was associated with other features of PsA at diagnosis. The upper and lower extremities were affected, predominantly asymmetrically, in 40% and 60% of the cases respectively. In patients with pitting edema compared to those without this feature, the frequency of Achilles enthesitis and plantar fasciitis, calculated together, was higher (p < 0.05) and the duration of arthritis was significantly lower (p = 0.02). In 7 patients the clinical evidence of a predominant involvement of tenosynovial structures was confirmed by MRI. CONCLUSION: Upper or lower distal extremity swelling with pitting edema due to tenosynovitis, usually unilateral, is a common feature in PsA patients and may represent the first, isolated manifestation of the disease.

Evaluation by captopril renal scintigraphy and echo-Doppler flowmetry of hypertensive patients at high risk for renal artery stenosis.

Sixty-three hypertensive patients with probability of obstructive renal artery disease underwent both Captopril renal scintigraphy (CRS) and echo-Doppler flowmetry (EDF) before undergoing renal angiography. Angiography revealed renal artery stenosis (RAS) in 42 patients (unilaterally in 26 and bilaterally in 16). The sensitivity and specificity in the identification of RAS > or = 50% were 90% and 94%, respectively for Captopril renography, and 85% and 78% for echo-Doppler flowmetry. Captopril renography correctly identified stenoses greater than 50%, which is usually held to be the limit of hemodynamic significance. While the Doppler examination was more sensitive than Captopril renography (sensitivity 79% versus 64%) in the detection of all degrees of RAS, less information on the functional significance of RAS was provided. Both CRS and EDF could be usefully employed to assess kidney perfusion, but their appropriate clinical use must take into account inherent differences between the two techniques.

[Rounded atelectasis of the lung].

Rounded atelectasis is an uncommon but increasingly recognized form of pulmonary collapse that often mimics a pulmonary neoplasm. It is suggested that these lesions can occur many years after exposure to asbestos or exudative pleural effusions. The authors report 16 cases of rounded atelectasis seen during a period of over 10 years, 9 of which in the last 18 months. They describe the plain film, tomographic and CT appearances of the lesion. The radiographic features that allow a diagnosis are rounded or oval shadows lying along the posterior surface of the lower lobe, adjacent to thickened pleura. Lateral tomography and CT show the blood vessels and bronchi curving toward the mass and converging on one edge, like a comet tail. Differentiation of rounded atelectasis from neoplastic disease is essential in avoiding unnecessary thoracotomy.
