Comparative Study[Procalcitonin in comparison to C-reactive protein as markers of the course of sepsis in severely immunocompromised children after bone marrow transplantation].
PCT has recently drawn attention as a quite specific marker for bacterial, fungal, and parasitic origin of severe sepsis-syndrome. These specific properties could make PCT to an important tool for sepsis monitoring in severely immunocompromised children. The clinical value of PCT in comparison to CrP was investigated in children after bone marrow transplantation (BMT). ⋯ (1) Measuring PCT levels in the sera of children undergoing BMT improves the possibility of diagnosing severe infection and gives an important prognostic tool. (2) Measuring PCT can be recommended if severe sepsis-syndrome is suspected and there is an additional need for differential diagnosis and prognostic evaluation.

Case Reports[Surveillance of nosocomial infections: prospective study in a pediatric intensive care unit. Background, patients and methods].
BACKGROUND, PATIENTS AND METHODS: From November 1997 through May 1998, the incidence of nosocomial infections was studied prospectively in a 10-bed multidisciplinary pediatric intensive care unit in Germany. A standardized surveillance [SEKI] system based on the National Nosocomial Infection Surveillance [NNIS] System of the Centers for Disease Control and Prevention [CDC] was used. The CDC definitions for nosocomial infections were adapted to the current practice of pediatric intensive care in Germany. Infection rates were calculated as infections per 100 patients, per 1000 patient-days, and per 1000 device-days (central venous catheters, urinary-catheters, and mechanical ventilation). ⋯ Surveillance data are indispensable for internal and external quality control, and prospective surveillance of nosocomial infections should become an essential component of hospital infection control programs in pediatric intensive care in Germany. The standardized calculation of (device utilization ratios and) device-specific infection rates yields results which can be compared with national and international surveillance data. SEKI meets the criteria of a practice oriented, prospective and standardized surveillance system. Considerable efforts for collecting and interpreting the required data should be balanced against the benefit of prevention of nosocomial infections in this population of critically ill persons.

[Verbal and nonverbal intelligence in children with language development disorders].
Difficulties in language acquisition seem to be serious, if there are additional problems like intellectual and/or emotional/social impairment, which are often reported [10]. These additional problems and the definition of specific language impairment as a developmental disorder, restricted to language acquisition seem to be contradictory [17]. ⋯ These additional cognitive problems indicate that there may be a more basic cognitive defect underlying specific language impairment [15]--at least for a group of specific language impaired children. Furthermore the nonverbal and verbal intellectual difficulties emphasize to general developmental support of specific language impaired children for optimal improvement in language acquisition.

Clinical Trial[Neoadjuvant therapy for localized osteosarcoma of extremities. Results from the Cooperative osteosarcoma study group COSS of 925 patients].
Owing to twenty years of multicentric interdisciplinary cooperation, the COSS group has been able to collect data on a large group of osteosarcoma patients treated by neoadjuvant therapy. This paper reviews results achieved in patients with localized extremity tumors. ⋯ Intensive multiagent chemotherapy and delayed surgery for localized extremity osteosarcoma led to excellent oncologic results in the COSS-studies. Tumor-size, -site, and -response as well as the intensity of upfront chemotherapy correlated with outcome. Giving doxorubicin and cisplatin by continuous infusions did not result in discernible prognostic disadvantages.

Currently, several clinical studies explore the therapeutic potential of tumor vaccines which are genetically modified to produce immunostimulatory molecules as a complementary approach for conventional cancer therapy. In this review the immunological basis and the preclinical design of such vaccine strategies are described with particular emphasis to acute leukemia and neuroblastoma. The role of cytokines, chemokines and costimulatory surface molecules for generation of tumor vaccines is summarized, and the advantages and disadvantages of autologous, allogenic and dendritic cell vaccines are discussed. Finally, combination-immunogens are introduced as a potent means of enhancing the anti-tumor response.
