Critical care medicine in the hospital: lessons from the EURICUS-studies.

We have performed a retrospective analysis of the EURICUS-studies using their database at the Foundation for Research on Intensive Care in Europe (FRICE) and other related documents, among which the various reports produced to the European Union which granted the studies, with the following purposes: a) to select and describe the most relevant observational and experimental results of the EURICUS studies; b) to inventory the main obstacles to the appropriate organization of intensive care medicine in the Hospital and c) to highlight amid the acquired knowledge those subjects which could have a direct and primary impact for improving the organization and management of intensive care units (ICUs). The EURICUS-studies have shown a rather non-systematic variation on the variables of the organization and management, resulting in a significant waste of resources and in a generally perceived insufficient performance of ICUs in Europe. Three major roadblocks were found: a) the lack of a clear concept of Critical Care Medicine; b) the lack of defined objectives both regarding the planning of the facilities and the activities to be developed in the ICU and c) the lack of a purposeful organization and management of work in the ICU. The further development and integration of each ICU in the Hospital should consider the following: a) the system approach to the analysis and standardization of processes of care; b) the redefinition of all jobs in each ICU; c) the definition of patient/nurse ratios in each ICU and sibling departments and d) to professionalize the organization and management of the ICU.

Adolescent melanoma: risk factors and long term survival.

AIMS: To report the adolescent melanomas with focus on differences in clinical characteristics, prognostic factors, disease free (DFS) and overall survival (OS) in comparison with adults. METHODS: A single institution retrospective study in which 49 adolescent patients were compared to an adult group of 972 patients. The 10-year DFS, 10-year OS and prognostic factors were calculated for both groups. RESULTS: The median age for the adolescent patients was 17 (range 12-19) years and 49 (range 20-93) years for the adult patients. Median follow-up time was 92 (range 4-366) months. Adolescent patients presented more often with locally advanced melanoma (p<0.01). The median Breslow thickness was 1.6 vs 2.0mm for the adults (p=0.075). Increasing age, ulceration, Breslow thickness, tumour location, male gender and stage at diagnosis were calculated to be negative prognostic factors for the adult group. In the adolescent group, only the stage at diagnosis was a significant negative predictor. The 10-year DFS and OS for the adolescent patients and adult group were not significantly different regarding AJCC stages I-III. CONCLUSION: Although adolescent patients presented more often with locally advanced disease, there are no significant differences in the 10-year DFS and OS between adolescent and adult patients. In our series, we could not confirm the prognostic factors found in the adult group for the adolescent patients, except for the stage at diagnosis.

Surgical treatment of recurrent pleomorphic adenoma of the parotid gland: a clinical analysis of 52 patients.

BACKGROUND: Surgical management of recurrent pleomorphic adenoma of the parotid gland has a considerable risk of facial nerve injury and a high re-recurrence rate. To obtain more insight into this issue we evaluated our experiences. METHODS: Medical records and histologic material of all these patients (31 women and 21 men), who had been treated from 1976-1995 were reviewed. Median interval between initial treatment and commencement of recurrences was 3 (0.8-18) years. Last surgery consisted of parotidectomy in 48 patients (92%), including 19 (40%) total procedures and wide local excision with involved skin in four patients. RESULTS: At a median follow-up of 9 years, eight patients (8/52; 15%) had re-recurrences develop, including 4 of 21 patients (19%) after a previous parotidectomy (group I) and 4 of 31 patients (13%) without prior parotidectomy (group II). The chance of re-recurrence in a group of patients with a minimal follow-up of 10 years after salvage surgery was 17% (4 of 24). The risk of a new relapse was, respectively, 4% and 8% at 1 and 5 years after treatment of recurrent disease. Acceptable N.VII function was preserved in 45 of the 49 (92%) nerves at risk. The risk of N.VII injuy was higher and more serious in group I (29% vs 10% in group II). The function of four of the five (80%) reconstructed zygomaticotemporal branches of the N.VII was adequate. CONCLUSION: Surgical treatment of recurrent pleomorphic adenoma of the parotid gland, usually consisting of a parotidectomy with wide extent and eventually facial nerve reconstruction, demonstrates favorable results with acceptable morbidity. The risk of new relapse and N.VII injury was higher after previous parotidectomy.
