Non-infectious complications of continuous ambulatory peritoneal dialysis: evaluation with peritoneal computed tomography.

The purpose of the study was to evaluate the non-infectious complications of continuous ambulatory peritoneal dialysis (CAPD) using peritoneal computed tomography (PCT). Twenty symptomatic patients were included in the study. Initially 2000 ml of dialysate fluid was infused into the peritoneal cavity and standard peritoneal computed tomography (SPCT) serial scans with 10 mm thickness were performed from the mid-thoracic region to the genital organs. Afterwards, 100 ml of non-ionic contrast material containing 300 mg/ml iodine was injected through the catheter and was distributed homogeneously in the intra-abdominal dialysate fluid by changing the positions of the patients; after waiting 2-4 h, the CT scan was released as peritoneal contrast computed tomography (PCCT). In patients (n = 20) both SPCT and PCCT revealed 90% (n = 18) pathological findings. But PCCT showed 60% (n = 12) additional pathological findings. We believe that PCT is beneficial for evaluation of non-infectious complications of CAPD. But PCCT is superior to SPCT in evaluating non-infectious complications encountered in patients on CAPD treatment.

Manometric study of complete ostial occlusion in chronic maxillary atelectasis.

The effect of complete ostial occlusion on static pressure within the human maxillary sinus has not been previously studied. In this study, a novel way to directly determine maxillary sinus pressure is described. Maxillary sinus pressures were measured in five patients with chronic maxillary atelectasis (CMA); these values were compared to values obtained from the contralateral side and from patients with chronic sinusitis. Measurements were made by introducing an 18-gauge needle probe through the membranous fontanel of the maxillary sinus and recording the pressure value with an amplified, pressure-sensitive transducer. The average value recorded in five patients with atelectasis of the maxillary sinus and complete ostial occlusion was -8.4 +/- 2.6 cm H20 (mean +/- standard deviation). Static pressure measurements of the contralateral antrum were isobaric, as were measurements found in patients with chronic sinusitis. This study reports for the first time the sinus pressure of completely occluded maxillary ostia in patients with CMA. These results may improve our understanding of the development of ostial occlusion and its role in the pathogenesis of CMA and sinusitis.

Tolerance to bilateral subcutaneous access nephrostomy in dogs.

Subcutaneous nephrostomy is a technique which allows access to the renal pelvis for physiological study in the experimental animal over a prolonged period of time without the complications attendant upon an externally draining appliance. One end of an 8 Fr. polyvinyl tube was placed in the renal pelvis at open surgery and the other end was capped and buried in the subcutaneous space for subsequent access by percutaneous needle puncture. This procedure is preferable to surgically created vesical exstrophy, exteriorization of the renal pelvis or conventional nephrostomy, techniques which have been proposed for such purposes. Tolerance to subcutaneous access nephrostomy was investigated in a group of 10 dogs followed for periods ranging from six months to two years. It was found that bilateral subcutaneous access nephrostomy did not alter kidney function but was associated with altered peristalsis. It was also associated frequently with bacteriuria, but not pyelonephritis. Neither calcific deposits nor calculi were seen as a consequence of the tube, and the procedure was well tolerated by the animal although, in some, progressive weight loss was observed. In general, this technique proved to be an excellent procedure for prolonged physiological studies of the urinary tract in dogs, and might similarly find some clinical application in humans.

Juvenile hyaline fibromatosis: two new patients and review of the literature.

We report on a sister and a brother (born to normal consanguineous parents) with joint contractures and osteolytic lesions of bones. The sister had also gingival hyperplasia and skin lesions consisting of multiple tumors of the face, nose, palate, ears, and neck. Histologic examination showed findings of juvenile hyaline fibromatosis. The literature is reviewed, and 15 cases already reported are summarized.
