Removal of infected epicardial electrodes by traction.
Five patients who had infected cardiac pacemakers with epicardial electrodes have been managed by exteriorization of the pulse generator and placement of an endocardial unit. In each case the remaining electrode leads where detached from the myocardium and removed by simple traction, avoiding a surgical procedure. In 4 patients, sets of cables had been sutured to the myocardium through an anterior thoracotomy, in some instances using Teflon pledgets as buttresses. In one of these procedures a pericostal suture had been used to secure the leads from the thoracic cavity against the ribs. The remaining patient had received a subxiphoid pacemaker also implanted with sutures. This is a consecutive series, and we have had no failures so far. All pulse generator units were bipolar and located beneath either the pectoral or the rectus muscle. All of them were functioning properly when infection was diagnosed. This procedure constitutes an alternative method of management when more conservative techniques, such as closed irrigation and debridement, cannot be utilized.

Intraoperative placement of central venous pressure monitoring cannulas.
A method for placement of central venous pressure monitoring and fluid administration catheters is described which we have found quite useful in our practice for the past three years in patients undergoing sternotomy incisions, most commonly for cardiac procedures.

Retroclavicular route for electrode placement in endocardial pacemakers.
In order to avoid skin erosion and electrode infection in endocardial pacemakers placed through the external jugular vein, we direct the wires from their point of entry into the vessel to the pacing unit placed in the pectoral region by dissecting a retroclavicular tunnel. This can be done under general or local anesthesia, and so far we have not seen any injuries to the subclavian vein. In this way the entire pathway of the cables is deep enough so that they cannot be palpated through the skin, and the dangers of exposure through erosion are minimized.

Fine needle aspiration cytology of granulomatous prostatitis.
The fine needle aspiration (FNA) cytologic findings are presented for 18 cases of granulomatous prostatitis (12 nonspecific, 5 tuberculous and 1 eosinophilic cases). These cases represented 19% of all prostatitis cases and 2% of all prostatic aspirates examined from January 1986 to December 1987. The cytomorphologic differences between the three types of granulomatous prostatitis are described, with emphasis on the differentiation between the nonspecific and specific varieties. The differential diagnostic features between reactive changes and well-differentiated adenocarcinomas of the prostate are also presented. The findings in these cases indicate that FNA cytology is a reliable procedure for the morphologic diagnosis of granulomatous prostatitis, which can clinically mimic prostatic carcinoma when it presents as a diffuse or nodular enlargement with increased consistency.

Fine needle aspiration cytology of soft-tissue lesions.
The use of fine needle aspiration (FNA) cytology was reviewed in 117 cases of soft-tissue lesions: 23 non-neoplastic lesions, 34 benign mesenchymal tumors and 60 histologically proven soft-tissue sarcomas. The soft-tissue sarcoma aspirates were classified according to their cytomorphology into five groups of possible histologic diagnoses. Difficulties were experienced in the correct diagnoses. Difficulties were experienced in the correct assessment of aspirates from low-grade malignancies. On the other hand, in high-grade malignant sarcomas and in recurrent or metastatic soft-tissue sarcoma, FNA cytology was useful in both the initial diagnosis of a new lesion (22 patients) and in the confirmation or exclusion of a suspected treatment failure (38 patients with recurrence or metastases). In the latter, FNA cytology supported the clinical data and reduced the number of repeat open biopsies. However, the final diagnosis of soft-tissue sarcomas should be based upon the histologic study of tissue sections.
