BACKGROUND Treatment of soft tissue sarcomas (STS) should only be initiated once the diagnosis is fully established. Resection of tumors of unknown nature should be avoided. Nevertheless, specialized centers continue to face numbers of unplanned excisions (UPE) in STS. AIM To compare oncologic and functional outcomes, number of surgeries, length of hospital stay and treatment costs of UPE versus planned excision (PE) in STS. METHOD A retrospective single tertiary center study was performed on 201 patients. Survival, local and distant recurrence rates were compared between PE (n = 137) and UPE (n = 64). In a subgroup analysis of 60 patients, functional outcome (MSTS and TESS scores), and socio-economic impact (number of surgeries, length of hospital stay and treatment costs) in "functional planned excision" (fPE) group (n = 30) and "functional unplanned excision" (fUPE) group (n = 29) were compared. selleck chemicals RESULTS There was no significant difference in oncological outcome between PE and UPE. In the subgroup analysis, we found a non-significant difference in functional outcome. Patients in the fUPE had significantly more surgeries (3.5 vs. 1.4; p less then 0.00001) and costs of their management was 64% higher than fPE (p = 0.048). Hospital stay was longer after fUPE but not statistically significant (18.3 days vs. 11.8 days; p = 0.13). CONCLUSION Even though oncological and functional outcomes are comparable after PE and UPE of STS, the number of surgeries, length of hospital stay and treatment costs were higher in patients with UPE. Our data underscore the importance of specialized STS treatment centers including multidisciplinary management. BACKGROUND Air pollution is one of the major health risk factors in urban populations. Air pollution has been associated with asthma in children. Air pollution has also been suggested to be distributed unequally within the cities, something that can lead to urban health inequalities. AIM We aimed to estimate the number of childhood asthma cases attributable to three main air pollutants; Nitrogen dioxide (NO2), Particulate Matter (PM 2.5), and Black Carbon (BC) in the city of Barcelona, Spain. We also aimed to describe the distribution of those impacts depending on the social deprivation index in Barcelona. METHODS We estimated the number of childhood asthma cases in Barcelona by applying a quantitative Health Impact Assessment (HIA) approach. Air pollution (NO2, PM2.5, and BC) exposure assessment was estimated using a land-use regression model. Two scenarios were assessed and compared the current levels of air pollution with 1) achieving the World Health Organization (WHO) guideline on exposure levels for NO2 between less and more deprived areas. CONCLUSIONS This study estimated that up to 1230 (48%) of asthma cases in Barcelona could be attributable to air pollution each year. This study also found that in Barcelona, less socially deprived groups could be more affected by asthma-related to air pollution than those more socially deprived. Sentinel node is defined as the first node to receive drainage from a primary tumor and seems to reflect the nodal status in the lymphatic drainage of the tumor. Sentinel node technique has modified the pathological examination of lymph nodes, with intraoperative evaluation of sentinel node, allowing immediate lymph node dissection in case of positive sentinel node, and histological ultrastratification to detect occult metastases. This is a literature review of different histological protocols of sentinel node according to different organs. Except for sentinel node in breast cancer and melanoma, intraoperative examination of sentinel node is helpful using frozen section, more sensitive than touch imprint cytology. Sentinel node should be embedded in paraffin block entirely after gross sectioning at two millimeters intervals parallel to the long axis of the node. Histological ultrastaging with serial sections can be helpful, but the number of sections and the interval between them is not codified. Three sections at 200-250 microns can identify the majority of micrometastases (200 microns). Systematic immunohistochemistry of sentinel node is not necessary for breast cancers, since isolated tumor cells do not modify the therapeutic strategy, but remains useful in other organs. BACKGROUND Still, the genetic basis of a large number of cases of early-onset isolated dystonia continues to be a mystery. In recent years, many new candidate genes are being identified as putative pathogenic factors in children with isolated dystonia due to the easy availability of whole-exome sequencing. Recently biallelic mutations in the COL6A3 gene were identified as a cause of rare dystonia (DYT)-27 syndrome. Till date, only six cases of DYT27 have been reported in the literature. METHODS We report a new case of COL6A3 mutation associated early-onset isolated dystonia-DYT27. We did a review of the previously published cases of DYT27. Citations were identified through PubMed, Embase, Web of Science and Google scholar searches using the search terms (including variations), "Dystonia-27 or DYT27" or/and "COL6A3 mutation associated early-onset isolated dystonia", combined with study filters for original research, case reports and case series. RESULTS Next-generation sequencing in the index patient revealed two pathogenic compound heterozygous loss of function mutations in exon 10 and exon 12 of the COL6A3 gene coding for the alpha(α)3(VI) chain of type VI collagen. Together with the presented case, seven cases (five males) were available for analysis. The median age at onset was 22 years (range 6-61). Dystonic symptoms were started from hands in five and from the neck in the remaining two patients. Five patients had favorable outcomes with trihexyphenidyl and botulinum toxin while tetrabenazine and levodopa were ineffective. CONCLUSIONS Although it is a new entity that is only recently discovered, in future years many more new cases suffering from this particular entity are likely to be reported and the already heterogeneous clinical spectrum is likely to be further widespread in years to come.
