A psychoanalytic reading of Peter Høeg's novel Miss Smilla's Feeling for Snow.

The author presents a psychoanalytic reading of the Danish author Peter Høeg's masterpiece 'Miss Smilla's Feeling for Snow', focusing on the special linguistic style of the novel. Further, the author puts forward an interpretation of the heroine, seeing her as a literary example of female bisexuality. Investigating the heroine's fate, the author discusses Miss Smilla's phallic defence and identity. The narrative technique in Høeg's novel is analysed through Lacan's concepts of the Real, the Imaginary and the Symbolic. The main figure is interpreted as an imaginary example of female bisexuality. Miss Smilla has neither an unambiguous gender identity nor ethnicity. The heroine is pictured in a conflict between two cultures: the Greenlandish and the western European, and her bisexuality both reflects this and is part of it. The author proposes to interpret a significant memory from Smilla's early childhood as an example of a castration phantasy, which retroactively gives new significance to the little girl's pre-oedipal frustration.

Pad-weighing test performed with standardized bladder volume.

The result of the one-hour pad-weighing test proposed by the International Continence Society has been demonstrated to depend on the urine load during the test. To increase reproducibility of the pad-weighing test by minimizing the influence of variation in urine load the test was done with a standardized bladder volume (50% of the cystometric bladder capacity). Twenty-five female patients with stress or mixed incontinence underwent two separate tests. Test-retest results were highly correlated (r = 0.97, p less than 0.001). Nonetheless, analysis of test-retest differences revealed a variation up to +/- 24 g between two tests. It is concluded that this setup (i.e., standardized bladder volume) of the one-hour pad-weighing test allows for a more reliable assessment of urinary incontinence for quantitative purposes.

Acute unilateral obstruction of ureter. Disparity in divided renal function calculated from 131I-hippuran and 99mTc-DTPA renography.

Fifteen patients with acute unilateral obstruction of ureter and 30 control patients were studied with simultaneous 131I-Hippuran and 99mTc-DTPA gamma camera renography. In severe outflow obstruction the relative function of the obstructed kidney was higher when calculated with Hippuran than with DTPA. No difference was found in the control subjects. This means that the glomerular filtration rate of an obstructed kidney may be relatively more reduced than the renal blood flow. Therefore, measurement of the single kidney fraction of total glomerular filtration rate has to be calculated with a glomerular filtered tracer, e.g., 99mTc-DTPA.

Subclavian vein catheterization for acute and chronic haemodialysis. A safe temporary vascular access.

The technique and use of a percutaneous subclavian vein catheter for haemodialysis in 20 patients are reported. The catheterization procedure carried a very low morbidity, and blood flow rates of 200-250 ml/min were achieved through the catheters. Use of this angioaccess saves future possible sites for permanent vascular access. Infectious complications were not encountered. Subclavian vein catheterization is a favourable alternative to external Silastic Teflon shunt.

Transabdominal dynamic ultrasonography in detection of bladder tumors.

The accuracy of dynamic transabdominal ultrasonography in the detection of bladder tumors is examined. Of 49 bladder tumors 34 between 2 mm. and several centimeters in size could be demonstrated ultrasonographically. Ultrasound failed to visualize tumors less than 5 mm. in size in 14 patients. Dynamic transabdominal ultrasonography cannot replace cystoscopy in the diagnosis or followup of patients with bladder tumors but it may be used instead of cystoscopy in some selected cases.

Differential diagnosis of jaundice: a pocket diagnostic chart.

Based on extensive clinical and clinical chemical information (107 different items) from 1002 jaundiced patients, we developed a diagnostic algorithm which was evaluated on a test sample of another 110 jaundiced patients. A primary classification into categories of obstructive jaundice (probability of obstruction greater than or equal to 0.80), non-obstructive jaundice (probability of obstruction less than or equal to 0.20), and of doubtful causes of jaundice (probability of obstruction: 0.20-0.80) was attempted. Among 234 patients in the data base who were classified as obstructive, 220 (94%) proved to be so, as did 36 (97%) of 37 in the test sample. The corresponding figures for non-obstructive jaundice were 463 (96%) of 483 patients correctly classified in the data base and 47 (92%) of 51 patients in the test sample. Altogether 69% of the patients in the data base and 75% of those in the test sample were correctly classified, in 27% and 20% the cause of jaundice was doubtful, and only 4% and 5%, respectively, were misclassified. A slight majority of the patients in whom the algorithmic diagnoses were doubtful proved obstructive. A close correlation was found between the preliminary diagnoses made by the algorithm and by the clinicians. A secondary classification of the patients by the algorithm into benign versus malignant causes of obstructive jaundice performed equally well in the data base and the test sample.

Abdominal ultrasonic scanning versus lymphangiography in testicular cancer.

Abdominal ultrasonic scanning was compared to lymphangiography and intravenous urography in 50 patients with testicular cancer. In 25 lymphangiographic stage I patients, the ultrasonic scanning was normal in all cases, too. In 5 out of 25 lymphangiographic stage II patients, the ultrasonic examination demonstrated a wider extension of the retroperitoneal metastases than combined lymphangiography and urography. The ultrasonically demonstrated masses were proven to contain malignant cells through an ultrasonically-guided fine-needle puncture in all 5 cases. Sufficient planning of the radiation ports would not have been possible in these patients without the additional ultrasonic scanning. In monitoring of the therapeutic response, ultrasonic scanning was found superior to lymphangiography.

Endoluminal ultrasonic scanning in the evaluation of rectal cancer: a preliminary report of 13 cases.

In 13 patients with a verified tumor of the rectum, endoluminal ultrasonic scanning was performed to evaluate the degree of tumor infiltration in the muscular wall and the perirectal tissue. In 11 cases the degree of tumor infiltration found by ultrasonic scanning was in complete accordance with the histopathologic finding. In 2 cases the examination was incomplete because the ultrasonic probe could not pass the tumor. We believe that endoluminal ultrasonic scanning will further development of the equipment will be a valuable additional diagnostic tool in the evaluation of gastrointestinal tract tumors. It will make it possible to decide whether local excision of the tumor is possible, based on the diagnostic procedure.

Kidney function and size in type 1 (insulin-dependent) diabetic patients before and during growth hormone administration for one week.

Kidney function and size were studied in seven well-controlled male Type 1 (insulin-dependent) diabetic patients before and after administration of highly purified human growth hormone for one week. Glomerular filtration rate, renal plasma flow (steady state infusion technique with urinary collections using 125I-iothalamate and 131I-hippuran), kidney size (ultrasonic scanning) and urinary excretion rates of albumin and beta-2-microglobulin were measured. Highly purified growth hormone was injected subcutaneously, 2 IU in the morning and 4 IU in the evening. The growth hormone dosage applied induced an elevation in plasma growth hormone concentration from the normal level seen in these very well controlled diabetics to levels within the range previously demonstrated in normally controlled Type 1 diabetic patients. During the week of growth hormone administration, glycaemic control was maintained unchanged by increasing the insulin dose by 79 +/- 9% (mean +/- SEM). Glomerular filtration rate increased from 122 +/- 3 to 131 +/- 3 ml/min X 1.73 m2 (p less than 0.05) and renal plasma flow increased from 535 +/- 10 to 569 +/- 22 ml/min x 1.73 m2 (p less than 0.05). Kidney size changed from 128 +/- 5 to 133 +/- 5 ml/1.73 m2 (NS). Urinary excretion rates of albumin and beta-2-microglobulin were unchanged. The present findings suggest that the growth hormone elevation typically found in Type 1 diabetic patients with reasonable clinical control, contributes to the enhanced glomerular filtration rate and renal plasma flow present in that disease.
