[A patient with Wegener's granulomatosis who worked in a foundry: a case for a causal association with silicon dioxide].

The diagnosis Wegener's granulomatosis was made in a 42-year-old man. Occupational history revealed prolonged exposure to large amounts of silicon dioxide in dust during work in a foundry. The illness was stabilized with immunosuppressive treatment, but after one year the patient developed aseptic necrosis in both hips, which ultimately led to essential total hip arthroplasty on the left side. The patient was unable to work since the diagnosis. Similar case reports have been described, as well as a limited number of case-control studies. These indicate an association between Wegener's granulomatosis and exposure to silicon. There is growing evidence for a causal role of silicon dioxide in the pathogenesis of auto-immune disease.

A pulmonary infection caused by Coprinus cinereus (Hormographiella aspergillata) diagnosed after a neutropenic episode.

In a patient treated for a non-Hodgkin's lymphoma, a lung abscess caused by Hormographiella aspergillata (stat. anamorph. Coprinus cinereus) was diagnosed using an ultrasound-guided puncture of the lesion. The patient appeared to respond to amphotericin B, but at the same time was also recovering from her neutropenic episode. The extent to which each of these two factors explains the complete resolution of the infection is unclear. Expert classical morphological examination and molecular typing methods were needed to identify this filamentous basidiomycetous fungus.

Sonographic detection of multiple Staphylococcus aureus hepatic microabscesses mimicking Candida abscesses.

We report the sonographic, CT, and clinical findings in a patient presenting with clinical sepsis and multiple Staphylococcus aureus hepatic microabscesses. Although contrast-enhanced CT has had a higher sensitivity than sonography in detecting hepatic microabscesses in some studies, this examination was negative in our patient. On sonography, numerous small hypoechoic lesions were present. Some target-like lesions had a striking similarity to Candida albicans microabscesses. The hepatic lesions were believed to be pyogenic liver microabscesses, as several blood cultures were positive for S. aureus. Following prolonged intravenous antibiotic therapy, all the hypoechoic hepatic lesions disappeared, along with the clinical and biochemical signs of sepsis.

Value of axillary ultrasonography and sonographically guided puncture of axillary nodes: a prospective study in 144 consecutive patients.

The value of axillary sonography in 144 consecutive patients was prospectively studied. Abnormal lymph nodes were demonstrated in 72 axillae, only half (36 of 72) of which were clinically detected. In comparison with intraoperative findings in 47 patients with breast carcinoma, the sensitivity of sonography in detecting malignant nodes was 92%, the specificity 95%, and the positive and negative predictive value 96% and 91%, respectively. In 42 patients a sonographically guided node puncture was performed. Evidence of malignancy was found in 38 (90.5%). In 14 (33%) of them, cyto-histology pointed to a clinically undetected primary malignancy.

Mucocele of the appendix.

We describe a case of mucocele of the appendix, observed incidentally in a 42-year-old man. The plain film, ultrasound and CT features are reviewed. Adequate diagnosis and resection are important because of the risk of rupture and development of pseudomyxoma peritonei.

Transition of renal arteriovenous fistula to arteriocalyceal fistula during embolization.

Selective and superselective renal embolization is a generally accepted technique for treating traumatic or iatrogenic renal arteriovenous fistulas or arteriocalyceal fistulas. Only a minority are pure arteriocalyceal fistulas. During embolization, an arteriovenous fistula may become a frankly bleeding arteriocalyceal fistula, causing massive haematuria and necessitating further embolization.

Parathyroid aspiration biopsy under ultrasonographic guidance.

Localization of hyperfunctioning parathyroid glands is difficult. We examined 16 patients with biochemically proven primary or secondary hyperparathyroidism, using a 5-MHz 90 degrees real-time sector transducer. In those 16 patients, ultrasonographically guided fine-needle aspiration biopsy of 26 hypoechogenic retrothyroid nodules was performed. Hyperplastic parathyroid tissue was obtained from 24 retrothyroid nodules in 14 patients. In the other two patients, normal thyroid tissue was obtained. Both specificity and sensitivity of the aspiration biopsy technique were 100%. No complications occurred. We concluded that this technique is safe, simple, and very helpful in the localization of parathyroid tumors before surgery or before alcoholization.

Complications of subclavian catheter hemodialysis: a 5 year prospective study in 257 consecutive patients.

The complications related to the use of subclavian catheters for hemodialysis were prospectively studied in 257 consecutive acute and chronic renal failure patients. Using 394 catheters, 3006 single needle dialyses were performed. Indications for starting catheter dialysis were mainly the absence or disappearance of an adequate vascular access. Most hazardous complications were sepsis (9), malposition (6), hemothorax (3), bleeding (2), vena cava thrombosis (2) and pneumothorax (2). A number of mechanical problems occurred, where the obstructed catheter could easily be replaced by a modified Seldinger technique. No mortal complications occurred. Patient tolerance was excellent. It is concluded that single needle subclavian hemodialysis is a valuable alternative vascular access method in acute situations. It enables the continuation of hemodialysis on an ambulatory basis.
