Severe hypothyroidism induced by amiodarone in a dialysis patient.

A 54-year-old man on regular haemodialysis developed severe amiodarone-induced hypothyroidism after an unusually short latency period. The iodide accumulation and/or the derangement in thyroid function associated with chronic renal failure may predispose uraemic patients to this serious side effect of amiodarone. Although the pharmacokinetics of amiodarone are not altered by renal failure, caution is advised in prescribing this drug to uraemic patients.

Hyperchloraemia: a non-specific finding in chronic renal failure.

To determine the prevalence of hyperchloraemia (plasma chloride concentration of 107 mmol/l or above) in chronic renal failure (CRF), we retrospectively analysed the acid-base and electrolyte status of 102 Italian and 53 English patients with impaired renal function. Hyperchloraemia was a frequent finding at all stages of CRF with a prevalence ranging from 30 to 50%. It was common both in tubulointerstitial nephropathies (45%) and chronic glomerulonephritis (39%). Hyperchloraemic patients were more acidotic than the normochloraemic.

The effect of dialysate temperature on haemodialysis leucopenia.

We assessed the influence of dialysate temperature on intra-dialytic leucopenia. Lowering dialysate temperature from 38 degrees C to 20.5 degrees C caused a decrease in the dialysis associated white blood cell reduction from 82 +/- 6 per cent to 32 +/- 19 per cent. The degree of leucopenia bore a highly significant relationship with dialyser blood temperature suggesting that a further lowering of blood temperature (to about 20 degrees C) would almost entirely prevent intra-dialytic leucopenia.

High-resolution CT angiography of the abdomen.

Multislice computed tomographic angiography (MSCTA) is a versatile technique that combines speed, excellent contrast, superb spatial resolution, and extreme simplicity. It has a wide range of applications in the abdomen including all vascular pathologies, occlusive or dilative, with excellent demonstration of atherosclerotic plaques in large or smaller branches. MSCTA is the method of choice in the follow-up of patients undergoing endovascular procedures for aneurysms. It provides excellent results in assessing vascular involvement by neoplasms arising from the liver, biliary tract, pancreas, kidneys, and all other abdominal organs. MSCTA can be used successfully in potential living donors and in the follow-up of recipients. Although MSCTA is a brand new technique, several developments are under investigation, which should allow further advancements in speed and spatial resolution.

Restorative proctocolectomy: morphological and functional study with coronal CT.

BACKGROUND: Restorative proctocolectomy with ileal pouch has become the surgical treatment of choice for patients with ulcerative colitis (UC) and familial polyposis of the colon. Defecography is the radiological technique commonly employed to obtain detailed information on function and morphology of the ileal pouch; it allows the direct visualization of the ileal pouch and the anal canal, but it does not provide the visualization of the pelvis. METHODS: In all patients, computed tomography (CT) on coronal planes was performed to determine its possibilities as an alternative to defecography; 10 patients with UC submitted to restorative proctocolectomy and were examined. RESULTS: Coronal CT images provided a panoramic vision of the pelvis and demonstrated the morphology of the ileal pouch, the thickness of its walls, and its correlation with the surrounding tissues. Coronal CT also allowed the evaluation of the continence of ileo-anal and ileo-ileal anastomosis and the functional changes of the perineal muscles at rest and during squeezing. CONCLUSION: CT images acquired on coronal planes allows an easy and clear detection of the major postoperative complications, such as stenosis or dehiscences of the anastomosis, pelvic phlogosis, and fistulae.

CT of Nissen's fundoplication.

The aim of this work is to describe the computed tomographic (CT) anatomy in patients who underwent Nissen's fundoplication. Forty patients (mean age = 61 years) with peptic esophagitis (nine cases), refractory gastroesophageal reflux (11 cases), and hiatal hernia (20 cases) were studied. Examinations were performed by third-generation CT equipment, with patients in the prone position after the ingestion of gastrovison and barium paste. In 34 patients, the examination demonstrated anatomical variations related to surgery, that is, the presence of a soft tissue mass at the level of the distal third of the esophagus. In four patients, a functional incompetence of the fundoplication (three cases) and a recurrent hiatal hernia (one case) were demonstrated. Our results suggest a possible application for CT study in postoperative follow up of patients who undergo Nissen's fundoplication, complementary to endoscopy and functional exams.

Diabetes and renal failure: a southern Italian perspective.

The authors carried out a retrospective survey assessing the total proportion of diabetic patients and relative proportion of patients with Type I and Type II diabetes among patients receiving renal replacement therapy and those evaluated for chronic renal failure in a southern Italian renal unit during the period 1972-1986. The proportion of diabetics among patients accepted for renal replacement therapy was 10% (34/336); of the 34 diabetic patients, only one was clearly affected by Type I diabetes, 26 had Type II diabetes, and the classification was uncertain in four patients. Similar relative proportions of Types I and II diabetes were observed among patients referred during the same period for evaluation of chronic renal failure.

Pancreatic beta-cell tumors: MRI.

Ten consecutive patients with surgically proven beta-islet cell tumors, strongly suspected clinically because of positive laboratory findings, were studied by MRI at 0.5 T. Results were correlated with CT and angiography. MRI detected all 10 insulinomas, with the location confirmed at surgery. Lesion size was < 1 cm in three cases, between 1 and 2 cm in five cases, and between 2 and 3 cm in two cases. A false-negative diagnosis was obtained with CT in 6 of 10 and with angiography in 3 of 10 cases. Our results suggest that if motion artifact can be controlled or reduced, MRI can be employed to localize insulinomas in patients with positive clinical and laboratory findings.
