[The role of PCR in detection of cytomegalovirus in blood and urine of transplanted patients].

Rapid and reliable laboratory diagnosis of cytomegalovirus (CMV) infection in transplanted patients becomes more significant considering possible prevention or moderation of CMV disease. The aim of this study was comparison of CMV isolation in cell culture and CMV detection by PCR in blood and urine samples of transplanted patients. The study comprised 21 patients undergoing immunosuppressive therapy after renal or bone marrow transplantation. MRC-5 cell culture was used for viral isolation. Inoculated cultures were maintained for 4 weeks or until appearance of specific cytopathic effect (CPE). Primers used in PCR were specific for the sequence within egzon 4 of immediate-early 1 (IE-1) gene. Presence of anti-CMV IgG and IgM antibodies was determined by ELISA. PCR was more sensitive for blood (4/21) and urine samples (3/19) than cell culture method--blood (0/21) urine (2/19). Statistically significant correlation was not shown between presence of CMV(determined by PCR) in blood and urine of the same patient.

[Myomectomy by vaginal route].

Myomectomy by vaginal route is the least invasive of all methods for myoma removal. Compared to classical, abdominal myomectomy, it has numerous advantages, especially in cases of fundal and posterior wall myomas, but still it is relatively rarely performed. This study provides an analysis of operative and postoperative course of patients subjected to myomectomy by vaginal route in the period from 01/01/2003 to 01/11/2005 as well as the corresponding control group of patients which had undergone classical, abdominal myomectomy. The study points out to significance and advantages of application of surgical technique for removal of myoma through the posterior wall of the vagina as opposed to classical, abdominal myomectomy. Transvaginal myomectomy eliminates trauma of laparotomy, intraoperative blood loss is reduced, postoperative complications are down to minimum, postoperative recovery is shorter, and so is the number of days spent in hospital. Thus, by performing this type of surgery, a positive cost-benefit effect is obtained not only for the patient but for health authorities as well.

[Correlation of diagnostic procedure with surgical findings in carotid stenosis].

Authors are discussing dilemma about necessary diagnostic procedure in making decision for surgical treatment of the carotid disease. Attitudes are changing and the old opinion of the necessity for angiogram of extra cranial blood vessels is substituted by the opinion that CDS (Color Duplex Scan) is satisfactory in the majority of cases to indicate of the surgical treatment. Comparing the invasive and noninvasive diagnostic's with operative findings, authors empirically confirm the given hypotheses, looking back to the cases where angiogram is necessary. The following issues were discussed: Estimate of the locaton of maximal shrinking, degree of shrinking, length of shrinking and characteristics of plaque as the most important parameters for indication and operative tactics. Diagnostics with CDS is shown as reliable with high degree of matching with operative findings.

[Eleven years of registration of congenital anomalies in Croatia associated with the EUROCAT international project].

Results of the eleven-year registration of congenital anomalies in Croatia are presented. Zagreb Registry as a part of international EUROCAT (European Registration of Congenital Anomalies) project covers four regional centers (Varazdin Rijeka, Pula and Koprivnica). The ascertainment, calculation of prevalence rates and statistical methods are based on EUROCAT method of investigation. Mean prevalence rate of 18.86/1000 births (1228 children with congenital anomalies per 65,100 births) was registered in the 1983-1993 period. The most frequently registered anomalies were congenital heart diseases, a heterogenous group of limb defects, oral clefts, central nervous system anomalies and chromosomal aberrations. The most frequent structural anomalies expressed as rates per 1000 births are ventricular septal defect (1.8), cleft lip +/- palate (1.1), atrial septal defect (0.8) polydactyly (0.8) and limb reduction defects (0.5). Statistical analysis shows a fluctuation of Down's syndrome prevalence rates during the monitored period. Statistically significant differences (p < 0.01) in prevalence rates among four regions of Croatia were established. The prevalence rates of marker anomalies (Down's syndrome, polydactyly, oral clefts) are tenfold higher compared to routine statistical data of Republic of Croatia. Acquired experience, collaboration and results obtained in this project represent a good basis for more rational planning of medical care and further investigation of this significant medical and public health problem.

[Monitoring the nutritional status in patients on hemodialysis].

In order to monitor changes of the nutritive status of hemodialyzed patients, antropometric and laboratory parameters of the population of hemodialyzed patients in 1988 vs. 1994 have been compared. Antropometric parameters were measured by the same investigator. The results show absence of significant difference between antropometric parameters (body weight after hemodialysis, body mass index, triceps fold, circumference of upper arm and percentage of fat) in the patients hemodialyzed in 1988. The laboratory parameters (albumin and transferrin), however, show significant increase in the 1994 group. In the group of patients subjected to hemodialysis in 1988 as well, albumin was significantly elevated. Nevertheless, no differences in laboratory parameters in healthy populations of 1988 and 1994 were noted (controls). It was concluded that no significant changes in the nutritive status were present among either the population or the same patients, while elevation of laboratory parameters necessitate further investigation.

[Analysis of data on hemodialyzed patients for the development of a data base].

Needs for state-of-the-art records on haemodialyzed patients implies abandoning of conventional paper work and development of a computer data base on haemodialyzed patients. Thus, data on haemodialyzed patients were analyzed. Since haemodialysis is a specific mode of treatment and differs from out-patient and in-patient management, the records also differ from conventional files and histories. The analysis has shown that the data can be groupedinto two sets: dialysis list and history of a haemodialyzed patient. The list contains the data at the onset of dialysis, and the end of the process, and in hourly intervals. The history contains mainly relatively permanent data (personal data and basal medical parameters), annual (records and primary data) and monthly (dialysis records, history and current condition, laboratory analyses and therapy). Most of the data are systematic, i.e. periodic and necessitate tabular presentation. It has been concluded that due to the tabular presentation and predominance of systematic information, the data base will be superior to conventional records.

Ureaplasma urealyticum infection in newborns: three case reports.

We report three newborns with different manifestations of Ureaplasma urealyticum infection; a term newborn with acute neonatal pneumonia and two very low birth weight infants with bronchopulmonary dysplasia and osteomyelitis of the femur, respectively. The association of U. urealyticum with acute and chronic respiratory disease in term and preterm newborns has recently been reported. Our two cases are similar to other case reports from the literature, but we were unable to find any previous reports of osteomyelitis due to U. urealyticum in the premature babies. Isolation of U. urealyticum in pure culture from the blood was considered to be related to local infection in all three patients. All patients were cured by erythromycin.

Responses of Purkinje cells of cerebellar vermis to sinusoidal rotation of neck.

1. The response of Purkinje (P) cells located in the vermal cortex of the cerebellar anterior lobe to sinusoidal rotation of the neck was investigated in precollicular decerebrate cats. The head of the animal was fixed in a sterotaxic frame while the spinous process of the second cervical vertebra was held by a clamp rigidly fixed to the tilting table. It was then possible to elicit a selective neck input by rotating the neck and the body simultaneously along the longitudinal axis of the animal while maintaining the head in horizontal position. 2. Among the 95 P-cells tested for neck stimulation, 35 units showed a mossy fiber (MF) or a climbing fiber (CF) response to sinusoidal rotation of the axis vertebra at the frequency of 0.026 Hz and at the peak amplitude of displacement of 5--10 degrees. The response consisted in a periodic modulation of the discharge frequency during sinusoidal rotation of the neck. Most of these units were excited during side-down rotation of the neck, but were inhibited during side-up rotation. 3. The threshold amplitude of neck rotation responsible for the MF-induced responses varied in different units from 1 to 3 degrees at the frequency of 0.026 Hz. The sensitivity of the units, expressed in percentage change of the average firing rate per degree of displacement, either did not change or very slightly decreased as a result of increasing amplitude of stimulation from 1--3 degrees to 10--15 degrees at the frequency of 0.026 Hz or by increasing frequency of neck rotation from 0.015 to 0.15 Hz at the amplitude of neck displacement of 5--10 degrees. 4. Changes in amplitude or frequency of stimulation at the parameters reported above did not greatly modify the phase of the unit responses relative to the side-down position of the neck. These findings indicate that the MF and CF responses of P-cells to sinusoidal rotation of the neck depended on changes in neck position and not on changes in velocity of neck rotation. 5. The observation that the majority of responding P-cells located in the vermal cortex of the cerebellar anterior lobe increased their firing rate during side-down rotation of the neck is discussed in relation to the results of stimulation and lesion experiments, indicating that postural changes can be elicited either during asymmetric stimulation of neck receptors or by unilateral interruption of the neck afferents.

Responses of Purkinje cells of the cerebellar vermis to neck and macular vestibular inputs.

1. The dynamic analysis of the control exerted by neck and macular vestibular receptors on the cerebellar cortex has been investigated in precollicular decerebrate cats submitted to sinusoidal rotation along the longitudinal axis of the animal at the frequency of 0.026 Hz and at peak amplitudes up to 10 degrees for the neck input and 15 degrees for the macular input. 2. Purkinje (P) cells located in the vermal cortex of the cerebellar anterior lobe, particularly in the longitudinal parasagittal zone which projects to the ipsilateral lateral vestibular nucleus (LVN), showed a sinusoidal modulation of the firing rate in response to sinusoidal stimulation of the neck receptors or the vestibular receptors, the phase of the responses being in most units related to the extreme neck or head position. Mossy fiber (MF) and/or climbing fiber (CF) responses of the same or different P-cells to the two inputs were observed. 3. The sensitivity of the MF-response of the P-cells to the neck input, elicited by sinusoidal rotation of the neck and expressed in per cent of the average firing rate per degree of neck rotation, corresponded on the average to 2.71 +/- 1.67, S.D. This value was significantly higher than that of the MF-response of the P-cells to the macular input elicited by sinusoidal tilt along the longitudinal axis of the whole animal, which correspond to 1.71 +/- 1.01, S.D. 4. Most of the MF-responses of the P-cells to the neck input were characterized by an excitation during side-down rotation of the neck and by an inhibition during side-up rotation, whereas most of the MF-responses of the P-cells to the macular input showed just the opposite behavior, being inhibited by side-down tilt of the animal and excited by side-up tilt. 5. Units which received a convergent input from both neck and macular receptors and showed an antagonistic pattern of response to the two inputs were tested during rotation of the head alone, in order to excite simultaneously the two kinds of receptors. Due to the higher sensitivity of the neck over the macular response, the magnitude of the combined response tended to be similar to the difference between the individual ones. Moreover, the phase of the resulting response was always modified with respect to that of the response to the neck input alone, and became in some instances related to velocity of neck rotation rather than to neck position. 6. These findings indicate that opposite responses to neck and macular inputs occur at corticocerebellar level. However, a final integration of the two inputs, leading to suppression of the conflicting responses, may occur either at medullary (LVN) or at spinal cord level.
