[Differential diagnosis of urinary retention: aneurysm of the iliac artery].

A 69-year old male presented with anuric acute renal failure. Abdominal ultrasound at admission revealed a mass in the pelvis thought to be the urinary bladder and the diagnosis of urinary retention was made. When placement of an urinary catheter did not induce urine flow, digital rectal examination was done. Palpation of a pulsating mass finally led to the diagnosis of aneurysm of the iliac artery. Based on this case, the general problem of diagnosing an iliac artery aneurysm is discussed.

[Fatal amnioinfusion with previous choriocarcinoma in a parturient woman].

The case of 36-year-old tercipare is described who developed choriocharcinoma in a previous pregnancy. During the first term labour the patient developed cardiac arrest, so reanimation and sectio cesarea was performed. A male new-born was delivered in good condition, but even after intensive therapy and reanimation occurred death of parturient woman with picture of disseminate intravascular coagulopathia (DIK). On autopsy and on histology there was no sign of malignant disease, so it was not possible to connect previous choricarcinoma with amniotic fluid embolism. Maybe was place of choriocarcinoma "locus minoris resistentiae" which later resulted with failure in placentation what was hard to prove. On autopsy we found embolia of lung with a microthrombosis of terminal circulation with punctiformis bleeding in mucous, what stands for DIK.

Renoprotective role of nifedipine during gentamicin therapy: randomized controlled trial.

AIM: To investigate the protective effect of nifedipine, a dihydropyridine calcium-channel blocker, on renal function (glomerular and tubular) in patients treated with gentamicin, an aminoglycoside antibiotic. METHODS: Thirty-two patients with gentamicin sensitive upper urinary tract infection have been screened and randomized to two groups. The placebo group was given gentamicin and placebo, and the intervention group gentamicin and nifedipine. Gentamicin was given in slow intravenous injection every 12 hours for 10 days, and nifedipine 10 mg orally, 3 times a day. RESULTS: Nifedipine administration during gentamicin therapy promoted primarily the glomerular filtration. In 62% of the patients treated with nifedipine creatinine clearance increased significantly by the end of the study. In the placebo group, 69% of the patients had a creatinine clearance significantly below the baseline at the end of the study. The decrease in creatinine clearance by more than 50% from the initial values was found in 2 patients (1 in each group). There was a significant increase in gammaGT/creatinine clearance ratio in both groups at the end of therapy, indicating that nifedipine did not prevent the brush-border membranous enzyme release caused by gentamicin. CONCLUSION: Nifedipine has positive effects on renal hemodynamics in patients treated with gentamicin. Most likely, the mechanism of action is an increase in glomerular filtration caused by preglomerular vasodilatation.

Influence of betaxolol and timolol on the venous tone in glaucoma patients.

The aim of this study was the assessment of physiological venous reflexes in 40 glaucoma patients treated with topically applied timolol maleate 0.50% and betaxolol HCL 0.50%. They were divided into two groups of twenty each; one group being given timolol and the other betaxolol. The assessment of the venous tone was performed by testing venous reflexes. We found no statistically significant difference between timolol and betaxolol; however, when the influence of circulating catecholamines and the other vasoactive substances was excluded by suprasphygmatic insufflation of a pediatric cuff, a significant difference was found in the Valsalva's maneuver (125.5 +/- 8.1 vs 85.0 +/- 34.3 venoconstrictive units VCUs, p = 0.03). The IOP was significantly decreased in both treatment group, although the pressure reduction effect was more pronounced in the timolol group. Our study suggests that timolol and betaxolol have a slightly different mode of action on the venous side of circulation under topical medications. It is possible that the use of betaxolol topically may reduce a systemic venoconstriction.

Peripheral nerve war injuries.

OBJECTIVE: The purpose of this study is to evaluate peripheral nerve war injuries sustained during the war in southern Croatia and Bosnia and Herzegovina. PATIENTS AND METHODS: During the war in Croatia, 713 patients (99% male and 1% female) with wounds inflicted by firearms were examined at the Laboratory of Neurophysiology, University Hospital, Split. The patients, soldiers and civilians alike, ranged in age from 6 to 73 years (average, 28 years). All patients with firearm nerve war injuries underwent detection by electromyography and plurisegmental examination of the damaged peripheral nerve (neurography). The patients were examined and controlled on three occasions: within 2 months after wounding; up to 6 months after wounding; and more than 6 months after wounding. RESULTS: Single peripheral nerve lesions were present in 80% of the patients, and multiple peripheral nerve or plexus lesions were present in 20% of the patients. Peroneal and ulnar nerves were most often involved (20.9% and 19.8%, respectively). Associated massive injuries to the muscles, large blood vessels, or vital organs were present in 45% of the patients. Wounds were inflicted by shell fragments in 80% of the patients and by projectiles in 20% of the patients. CONCLUSION: According to our results, better recovery was achieved with conservative treatment and when physical therapy was initiated early with maximal patient cooperation. Electromyoneurographic findings were the most valid in the prognostic classification of war-inflicted peripheral nerve injuries.
