The dream space and countertransference.

The author describes some similarities in the psychoanalytic literature between the conceptualisation of the dream space and that of the analyst's function as a container of the patient's projections. He also notes the correspondence between the creative use of a dream and the use of an analytic session to further understanding. Detailed clinical material is then presented from the analysis of two male patients, both of whom were unable to complete a dream about a particular emotional dilemma. The way in which they created severe disturbance in the countertransference at the same time is reported. The analyst's struggle to work through this difficulty and the beneficial consequences of this for the patient are described. It is argued that this demonstrates the way in which patients may project into the analyst dilemmas that they are unable to dream about in order that the analyst's functioning may transform the dilemmas into ones that can be thought and dreamt about. It is further argued that some patients have a developmental need to engage the analyst in this way.

[Anti-proteinuria effects of nonsteroidal anti-inflammatory drugs in patients with nephrotic syndrome: an illusion or a read improvement?].

In order to examine the antiproteinuric effect of non-steroidal antiinflammatory drugs in patients with nephrotic syndrome, we performed a parallel determination of the daily proteinuria, strength of glomerular filtration and of the effective renal plasmatic flow in basal conditions and after a 7 day ibuprofen therapy at a daily dose of 1200mg (3 x 400mg) in a group of 12 patients with idiopathic glomerulonephritis. In all patients ibuprofen therapy induced a significant decrease of the existing proteinuria, but this decrease was accompanied by the decrease of clearance rate of 99mTc-DTPA and 131J-hipuran clearance, that is by decrease of strength of glomerular filtration (averagely 24.29%) and effective renal plasmatic flow (averagely 18.74%). It can be concluded that the decrease of proteinuria in patients with nephrotic syndrome after ibuprofen therapy (as well as other non-steroidal antiinflammatory drugs) is primarily the result of worsening of hemodynamic conditions in the kidney, that it is caused by the reduction of the renal blood flow and by the strength of glomerular filtration in conditions of cycloxygenetic activity inhibition in the kidney.

Effects of nonsteroidal antiinflammatory drugs on renal plasma flow and glomerular filtration rate in patients with glomerulonephritis.

We investigated the effects of NSAIDs (Ibuprofen) on renal plasma flow (RPF) and glomerular filtration rate (GFR) in patients with glomerulonephritis. The study included 98 patients (53 men and 45 women) with idiopathic glomerulonephritis. All of the patients received Ibuprofen 1200 mg (3x400) during 7 days. Before and after the treatment with Ibuprofen ERPF (clearance of 131I-Hippuran) and GFR (clearance of 99mTc-DTPA) were determined. In our patients administration of Ibuprofen was associated with a significant reduction in renal plasma flow and glomerular filtration rate. In patients with reduced renal function the decrease in RPF and GFR after Ibuprofen was significantly greater than in patients with normal renal function.

[Radionuclide functional tests in transplanted kidneys].

Results of 140 combined first-pass and dynamic functional renal studies were clinically evaluated in 50 patients with a transplanted kidney. The renal handling of three different nephroaffine radionuclides, namely the glomerular agent (99m Tc-DTPA), the predominantly tubular agent (99m TcMAG3) and combined glomerulo-tubular agent (99m Tc-PAHIDA) was also analysed in various dysfunctions of renal transplants. It has been concluded, that the clinically most useful information at all levels of the overall renal function has been given by 99m TcMAG3. However, the behaviour of glomerular and tubular agents in postischaemic acute tubular lesion was found to be discordant which in turn could be valuable differential-diagnostic information, and out of this reason their successive application is essential. The combined firstpass and dynamic functional renal studies have been judged as a helpful diagnostic tool in the follow-up of patients who have undergone kidney transplantation, provided that its results are interpreted in the light of clinical and other relevant findings.

[The importance of beta-2 microglobulin determination in the urine in the detection of tubular proteinuria].

In 38 patients with the positive finding of protein in the urine the determination of beta-2 microglobulin concentration was made in addition to the simultaneous determination of albumin, IgC and transfer in the urine and the calculation of differential protein clearance values for the identification of tubular proteinuria. Only 4 (10.53%) patients had proteinuria of tubular type, 16 patients had proteinuria of glomerular type, while proteinuria of the mixed glomerulo-tubular type was found in 18 (47.37%) patients. The safe separation of tubular proteinuria from that of glomerular type was made possible by the determination of beta-2 microglobulin concentration in the urine in the framework of detailed investigation.
