[Correlation of urography, ultrasonography and computer tomography with clinical findings in examinations of the kidneys and retroperitoneum. Possibilities of diagnostic errors].

The authors prospectively and retrospectively mutually compared the diagnostic value of urography, ultrasonography (USG), and computer tomography (CT) in four patients, with the diagnosis misstated prior to operation. The most valuable findings were provided by CT. Mere utilization of these methods does not exclude the possibility of diagnostic misstatements. In three patients the ultimate diagnosis was assessed on the basis of operative revision and in one patient, by means of cytologic examination of the renal punctate. Owing to retrospective evaluation of examinations, diagnostically valuable symptoms which could have lead to the correct diagnosis, were distinguished. Hence, examinations must necessarily be evaluated in complex with the general clinical state. (Fig. 6, Ref. 14.).

[Atrial-triggered and ventricular-inhibited ventricular VDD pacing with atrial and ventricular single catheter electrodes--the Phymos MPS pacemaker].

Optimal treatment from the haemodynamic aspect in complete atrioventricular block is dual-chamber DDD pacing. It makes possible atrioventricular sequence and adaptability of the frequency of ventricular pacing to the load under the control of the sinoatrial node. DDD pacing calls, however, for an atrial and ventricular electrode on two leads. Italian authors developed in 1984 a pacemaker (PM) PHYMOS (MEDICO ITALIA) which makes possible atrial triggered ventricular VDD pacing by means of a single pass lead with a tripolar electrode. As the first ones in the post-communist countries the authors implanted to six patients a PM PHYMOS MPS. They confirmed that the advantages of the VDD system, as compared with DDD, are the use of a single pass lead. This makes the implantation quicker, simpler and safer and reduces the time of X-ray irradiation and the incidence of electrodes dislocations. Another advantage is the lower incidence of atrial fibrillation and probably also pacemaker mediated tachycardias. The disadvantages of the VDD system are that atrial stimulation is impossible and that the diameter of the single pass lead is somewhat larger. According to data in the literature and the so far small experience of the authors, when the indication is correct--atrioventricular block grade III or II with intact function of the sinoatrial node--the advantages of VDD pacing with a single pass lead, as compared with DDD pacing, predominate over disadvantages.

[The genetic contribution of cows to the prevalence of mastitis in the following generation].

Investigations of mastitis prevalence were performed in 1227 dam-daughter pairs during 1985-1988. From the records of the last 10 years, the findings concerning mammary gland were obtained. Six herds of agricultural co-operatives in the Brno region were investigated. In the early period the Bohemian Pied breed, later the crosses of this breed with Red Holstein and a low genetic proportion of Ayrshire cattle, dominated in the set of cows. Udder health was assessed using the clinical and bacteriological findings in individual udder quarters and the results of the rapid mastitis test NK. Based on this data, the cows were divided into two groups--resistant and susceptible. The lactation order in which the disease appeared for the first time was of great importance. The occurrence of the disease in daughters and udder health in dams were in a significant relation (P less than or equal to 0.01). While nearly 50% of daughters of susceptible dams were affected, it was only 25% in daughters of the resistant group. The assessment of heritability of resistance to mastitis was carried out on the principle of dam-daughter regression. The index of heritability ĥ2 = 0.52 +/- 0.06 was calculated. The results show that the genetic contribution of dams to the susceptibility of daughters to mastitis is significant.

Extracorporeal shock wave lithotripsy for ureteral stones: a retrospective analysis of 417 cases.

We treated 417 patients with upper ureteral stones with extracorporeal shock wave lithotripsy. All patients with obstructing stones underwent retrograde manipulation, which was successful in 57 per cent. Management of obstructing stones in situ (215 patients) with and without decompression of the collecting system required additional treatments in 13 per cent and ancillary procedures in 25 per cent. Nonocclusive ureteral stones were not manipulated. Treatment of these stones in situ slightly increased the need for postoperative ancillary procedures, compared to successful repositioning into the kidney (5.9 versus 3 per cent). Secondary treatments, however, were necessary as often as with occlusive stones. The main reason for failure of extracorporeal shock wave lithotripsy was the lack of fluid around an impacted stone. An energy absorptive effect of muscle tissue for stones projecting on the psoas muscle could not be demonstrated. The best and most consistent results were obtained when the stone was manipulated successfully into the renal collecting system.

[Does human fibrin glue improve results in tympanoplasty?].

Human fibrin tissue adhesive diminishes the rate of recurrent perforations in tympanoplastic on a statistical base (n = 1051). The postoperative air-bone gap (1000 cps) was not influenced in a substantial amount by using tissue adhesive. The reconstruction of the lateral attic wall by endogenous conchal cartilage was facilitated by the application of fibrin tissue adhesive. In animal experiments with guinea pigs ("attic" of bulla tympanica) human fibrin tissue adhesive is superior to free muscle transplants in reconstruction of the bony bulla wall. Fibrin adhesive induces scar formation, therefore a very sparing use is necessary.
