Is detection of bacterial DNA in ascitic fluid of clinical relevance?

In patients with cirrhosis, bacterial DNA has been found in ascites reflecting bacterial translocation. However, the clinical relevance of this finding is ill-defined especially compared with the standard diagnostics for detection of spontaneous bacterial peritonitis (SBP). Furthermore, other DNA tests have not been sufficiently evaluated.

Posterior versus anterior circulation strokes: comparison of clinical, radiological and outcome characteristics

Physicians treating patients with posterior circulation strokes (PCS) tended to debate more on whether or not to introduce anticoagulation rather than performing investigations to identify stroke aetiology, as in patients with anterior circulation strokes (ACS). Recent findings suggest that stroke aetiologies of PCS and ACS are more alike than dissimilar, suggesting that PCS deserve the same investigations as ACS. The characteristics and current diagnostic evaluation between patients with PCS and ACS were compared.

Successful treatment of childhood high-risk hepatoblastoma with dose-intensive multiagent chemotherapy and surgery: final results of the SIOPEL-3HR study

The primary objective was to determine the efficacy of a newly designed preoperative chemotherapy regimen in an attempt to improve the cure rate of children with high-risk hepatoblastoma.

Phase I/IIa study of cilengitide and temozolomide with concomitant radiotherapy followed by cilengitide and temozolomide maintenance therapy in patients with newly diagnosed glioblastoma

Invasion and migration are key processes of glioblastoma and are tightly linked to tumor recurrence. Integrin inhibition using cilengitide has shown synergy with chemotherapy and radiotherapy in vitro and promising activity in recurrent glioblastoma. This multicenter, phase I/IIa study investigated the efficacy and safety of cilengitide in combination with standard chemoradiotherapy in newly diagnosed glioblastoma.

Intensified chemotherapy and dose-reduced involved-field radiotherapy in patients with early unfavorable Hodgkin's lymphoma: final analysis of the German Hodgkin Study Group HD11 trial

Combined-modality treatment consisting of four to six cycles of chemotherapy followed by involved-field radiotherapy (IFRT) is the standard of care for patients with early unfavorable Hodgkin's lymphoma (HL). It is unclear whether treatment results can be improved with more intensive chemotherapy and which radiation dose needs to be applied.

Impact of single nucleotide polymorphisms and of clinical risk factors on new-onset diabetes mellitus in HIV-infected individuals

Background. Metabolic complications, including cardiovascular events and diabetes mellitus (DM), are a major long-term concern in human immunodeficienc virus (HIV)-infected individuals. Recent genome-wide association studies have reliably associated multiple single nucleotide polymorphisms (SNPs) to DM in the general population. Methods. We evaluated the contribution of 22 SNPs identifie in genome-wide association studies and of longitudinally measured clinical factors to DM. We genotyped all 94 white participants in the Swiss HIV Cohort Study who developed DM from 1 January 1999 through 31 August 2009 and 550 participants without DM. Analyses were based on 6054 person-years of follow-up and 13,922 measurements of plasma glucose. Results. The contribution to DM risk explained by SNPs (14% of DM variability) was larger than the contribution to DM risk explained by current or cumulative exposure to different antiretroviral therapy combinations (3% of DM variability). Participants with the most unfavorable genetic score (representing 12% and 19% of the study population, respectively, when applying 2 different genetic scores) had incidence rate ratios for DM of 3.80 (95% confidenc interval [CI], 2.05–7.06) and 2.74 (95% CI, 1.53–4.88), respectively, compared with participants with a favorable genetic score. However, addition of genetic data to clinical risk factors that included body mass index only slightly improved DM prediction. Conclusions. In white HIV-infected persons treated with antiretroviral therapy, the DM effect of genetic variants was larger than the potential toxic effects of antiretroviral therapy. SNPs contributed significantl to DM risk, but their addition to a clinical model improved DM prediction only slightly, similar to studies in the general population.

Psychological distress in adult survivors of childhood cancer: the Swiss Childhood Cancer Survivor study

Purpose To evaluate the degree of psychological distress in adult childhood cancer survivors in Switzerland and to characterize survivors with significant distress. Methods Childhood cancer survivors who were age younger than 16 years when diagnosed between 1976 and 2003, had survived more than 5 years, and were currently age 20 years or older received a postal questionnaire. Psychological distress was assessed using the Brief Symptom Inventory (BSI). Raw scores were transformed into T scores according to the German norm sample, and the proportion of participants being at increased risk for psychological distress was calculated (case rule: T ≥ 63). t tests and univariable and multivariable logistic regressions were used for statistical analyses. Results One thousand seventy-six survivors (63.% of eligible survivors, 71.9% of contacted survivors) returned the questionnaire, 987 with complete data on BSI. Comparison with the norm populations showed lower T scores (T < 50) in the Global Severity Index (GSI; T = 46.2), somatization (T = 47.6), obsessive-compulsive tendencies (T = 46.9), and anxiety (T = 48.4). However, more childhood cancer survivors (especially women) had increased distress for GSI (14.4%), interpersonal sensitivity (16.5%), depression (13.4%), aggression (16.9%), and psychotic tendencies (15.6%) than the expected 10% from the norm population. Caseness was associated with female sex, being a single child, older age at study, and self-reported late effects, especially psychological problems. Conclusion Results show that childhood cancer survivors, on average, have less psychological distress than a norm population but that the proportion of survivors at risk for high psychological distress is disproportionally large. Monitoring psychological distress in childhood cancer survivors may be desirable during routine follow-up, and psychological support should be offered as needed.

[Analysis of clinical forensic examination reports on sexually abused children]

Clinical forensic examinations of children suspected of having been sexually abused are increasingly part of the routine of medicolegal institutes. The findings collected from 2005 until 2007 at the Institute of Legal Medicine of the Hanover Medical School were analysed retrospectively. Altogether, 91 children (74 females, 17 males, mean age 8.7 years) were examined. In 87.9% of the cases, the examination had been ordered by the police. In 73.6%, the victim knew the suspected perpetrator well or he was a family member. 40.7% of the children were seen within 72 hours after the alleged abuse. 12.1% of the children had extragenital lesions. In 27% of the victims, marked anogenital injuries were found, which were characteristic of sexual abuse in 9%. In 18 cases (20.2%), swabs were taken for spermatozoa detection. 3 of 17 vaginal smears showed positive test results for sperm up to 21 hours after the incident. No spermatozoa could be detected in 4 anal and 2 oral swabs as well as in one swab taken from the skin of the victim's thigh. In summary, the evaluation shows that early clinical forensic examination of children suspected of having been sexually abused is crucial to document evidence that is highly significant for the investigation and court proceedings. Often suspected sexual child abuse cannot be proved by medical findings alone. Of course, the absence of anogenital injuries does nor rule out sexual abuse.

Analysis of clinical forensic examination reports on sexual assault

Medical-forensic examination of sexual assault victims and alleged offenders is a common task of many forensic institutes. In the current study, the results from samples taken at the Institute of Legal Medicine, Hanover Medical School, during a period from 2005 to 2007 were retrospectively evaluated. In total, 292 victims (283 females and nine males) and 88 suspects were examined. At the time of the assault, 41.8% of the victims and 43.2% of the alleged perpetrators were under the influence of alcohol. Injuries were found in 84.9% of the victims and 39.8% of the suspects. Thirty victims (10.3%) reported having been choked or strangled. Cytology was performed in 218 victims. In 81 cases (38.0%), sperm could be detected in vaginal swabs up to 3 days post-assault. In seven (18.9%) out of 37 anal samples, evidence of sperm could be found 24 h post-assault. None of 22 oral samples was positive for sperm. Out of 301 sexual assault cases, 171 could be proved by means of medical-forensic examination. In summary, our evaluation shows that an early medical-forensic examination of both victim and suspect can secure numerous medical findings. Furthermore, persons intoxicated by alcohol, handicapped persons and persons with psychiatric disorders are more vulnerable to become a sexual assault victim.
