Whole body content and turnover of Cs and K.

In persons who had accumulated radiocesium from the fallout of the Chernobyl nuclear reactor accident, the amount of radiocesium and radiopotassium was measured in the total body and in urine. The stable Cs content in the urine was determined at the same time by instrumental nuclear activation analysis. From the data obtained, the total body Cs pool was calculated to be 1500 micrograms, that of K 110 g. The Cs turnover rate was found to be 0.64%/d for men and 0.81 for women; the K turnover 2.4 and 2.7, respectively. The Cs:K ratio in the total body was 4 times higher than that in urine, demonstrating that, in relation to the intake, the body is able to accumulate more Cs than K.

Cerebral microembolus generation in different extracorporeal circulation systems.

Microemboli generated during extracorporeal circulation (ECC) are likely to induce neurological sequelae. This study examines whether the choice of a distinct type of ECC can reduce intracerebral emboli counts. Middle cerebral artery blood flow during coronary artery bypass grafting was monitored continuously by transcranial Doppler ultrasound in 45 patients. The ECC systems used were a roller pump (n = 16), a centrifugal pump (n = 18) and a combination of centrifugal pump and heparin-coated ECC system (n = 11). Patients' characteristics as well as surgical and anesthesiological procedure did not differ between the groups. Total counts did not differ significantly between the three groups. Intraoperative events in individual patients may lead to massive embolus generation overcoming positive properties of a distinct ECC system.

Psychopathological symptoms of depression in Parkinson's disease compared to major depression.

Parkinson's disease is frequently associated with depressive symptoms. When depression occurs at early stages and before the onset of characteristic motor symptoms of the disease, differential diagnosis of major depression may be difficult. Differences in psychopathological features of depression in Parkinson's disease and major depression have been reported by some authors. This study presents data of 49 patients with depression in Parkinson's disease and 38 patients with major depression. The severity of depressive symptoms was equivalent in both groups. Depressive features did not differ between the two groups with exception of affective flattening, delusional ideas and suicide attempts. In conclusion, this investigation gives support to the assumption of a common neurobiological origin of depression in Parkinson's disease and major depression.

Changes in patient perception and behavior following Mohs micrographic surgery.

BACKGROUND: Mohs micrographic surgery (MMS) is used for the removal of difficult or recurrent skin cancer. Little is known about the behavioral changes of patients who have undergone this procedure. OBJECTIVE: This study was conducted to document patients' long-term psychological and behavioral changes following MMS. METHODS: A survey was mailed to a sample of 260 persons who underwent the Mohs procedure in 1997. It included questions on sunscreen use, level of anxiety about cancer, patient confidence in MMS, and changes in high-risk habits. RESULTS: The study included 214 patients who responded to our mailed questionnaire. Trends showed an increase in some but not all preventative measures taken to avoid skin cancer recurrence post-MMS. Other healthy lifestyle changes, such as decreased cigarette smoking, were not noted. CONCLUSION: Mohs micrographic surgery has an impact on some aspects of patients' health-related behavior, especially skin cancer prevention. Other aspects which are not affected may be targets for extra patient education.

After the shaking stops. Catholic healthcare workers should prepare for seismic changes.

In an attempt to cap spiraling costs and remain competitive, both providers and insurers are going through a frenzy of consolidation. Experts are predicting these changes: The integrated delivery system (IDS) will be the prevailing type of healthcare organization. There will be fewer acute care beds and fewer hospitals. Hospitals will be subsidiary to IDSs. Catholic and non-Catholic providers will join together to form IDSs. Regional IDSs will join statewide networks. The Catholic healthcare ministry can survive in such an era of consolidation if its leaders (1) collaborate with others on a basis of shared values, (2) have a well-defined mission, (3) provide holistic care, and (4) ensure that the organization remains true to its mission and demonstrates core values in its decisions and behaviors. Sponsors will need to find ways to share management of IDSs with non-Catholic organizations; to collaborate in the formation of regional and statewide IDSs; to urge other Church leaders to support social justice, human dignity, and community service; to be mindful of the stresses these changes will place on physicians and employees; to encourage dialogue about other changes in religious life; and to prepare laypersons to be their successors in the leadership of Catholic healthcare.

Occult paravalvular leak in a clinically normal St. Jude's mitral valve presenting with life-threatening microangiopathic hemolytic anemia.

A case of microangiopathic hemolytic anemia associated with a St. Jude Medical prosthetic paravalvular valve leak, not detected by echocardiography or cardiac angiography and requiring thoracotomy for diagnosis and therapy is described. The importance of considering the presence of a paravalvular leak in a patient with MAHA and a prosthetic valve even with a negative invasive cardiac work-up is discussed.

[Perioperative CTG in cesarean section].

In 30 cases each of primary (intact amnion) and secondary (ruptured amnion) cesarean section continuous perioperative cardiographic monitoring of the fetus was performed. When primary cesarean section is performed, perioperative monitoring extending to delivery of the fetus is not generally necessary, provided the preoperative CTG is normal and the patient is positioned on her left on the operating table. In secondary cesarean section with normal CTG continuous perioperative monitoring of the fetus is also unnecessary. If secondary cesarean section is performed when the amnion is ruptured and the CTG is pathologic, the fetus should be cardiotocographically monitored up to delivery, to permit the speed of preparation and performance of the operation to be adapted to the condition of the fetus and any necessary preparations for reanimation to be made.

[Can premature birth rate be reduced by preventive cerclage? A retrospective statistical analysis on the effect and value of cerclage using the Bavarian Perinatal Survey 1978-1980].

There is no simple correlation between cerclage rates and premature birth-rates. This concludes that premature birth-rates cannot be reduced by extending the cerclage. In all comparable categories the premature birth-rate was higher in groups which used the cerclage than those ones which did not use the cerclage even though a) the risk of social economical premature birth-rates was reduced and b) care was intensified for pregnancy cases. Cerclage groups have a higher percentage of case history risks than the non-cerclage groups. There is a direct relationship between the social status and the premature births. The case history of premature birth risks cannot be reduced using the cerclage especially with women who have previously had 2 abortions or premature births. When placenta previa occurs the cerclage does not reduce premature births. In the case of cervix insufficiency and early labor the cerclage reduces the premature birth-rate. Extended prophylactic cerclage cannot be used to diminish premature births.

[Can by preventive cervix cerclage the premature birth rate in multiple pregnancy be reduced? A retrospective statistical analysis on effectiveness of cerclage using the Bavarian Perinatal Survey 1978-1980].

Through a retrospective statistical analyzation of 3081 multiple births with 907 cerclage of BPE from 1978-1980, among which included 77 multiple births and 61 Cerclage cases of the Amberg gynecology clinic, could be proved that the liberal use of prophylactic cerclages could not reduce the premature birth rate of multiple birth pregnancies.
