Radical trachelectomy is the treatment of choice in women with early-stage cervical cancer wishing to preserve fertility. Radical trachelectomy can be performed with a vaginal, abdominal, or laparoscopic/robotic approach. Vaginal radical trachelectomy (VRT) is generally not offered to patients with tumors 2 cm or larger because of a high recurrence rate. There are no conclusive recommendations regarding the safety of abdominal radical trachelectomy (ART) or laparoscopic radical trachelectomy (LRT) in such patients. Several investigators have used neoadjuvant chemotherapy in patients with tumors 2 to 4 cm to reduce tumor size so that fertility preservation may be offered. However, to our knowledge, no published study has compared outcomes between patients with cervical tumors 2 cm or larger who underwent immediate radical trachelectomy and those who underwent neoadjuvant chemotherapy followed by radical trachelectomy. We conducted a literature review to compare outcomes with these 2 approaches. Our main endpoints for evaluation were oncological and obstetrical outcomes. The fertility preservation rate was 82.7%, 85.1%, 89%; and 91.1% for ART (tumors larger than > 2 cm), ART (all sizes), NACT followed by surgery and VRT (all sizes); respectively. The global pregnancy rate was 16.2%, 24% and 30.7% for ART, VRT, and NACT followed by surgery; respectively. The recurrence rate was 3.8%, 4.2%, 6%, 7.6% and 17% for ART (all sizes), VRT (all sizes), ART (tumors > 2 cm), NACT followed by surgery, and VRT (tumors > 2 cm). These outcomes must be considered when offering a fertility sparing technique to patients with a tumor larger than 2 cm. © 2015 Elsevier Inc. All rights reserved.

Objectives: The objectives were to evaluate the diagnostic accuracy for sepsis in an emergency department (ED) population of the cluster of differentiation-64 (CD64) glycoprotein expression on the surface of neutrophils (nCD64), serum levels of soluble triggering receptor expressed on myeloid cells-1 (s-TREM-1), and high-mobility group box-1 protein (HMGB-1). Methods: Patients with any of the following as admission diagnosis were enrolled: 1) suspected infection, 2) fever, 3) delirium, or 4) acute hypotension of unexplained origin within 24 hours of ED presentation. Levels of nCD64, HMGB-1, and s-TREM-1 were measured within the first 24 hours of the first ED evaluation. Baseline clinical data, Sepsis-related Organ Failure Assessment (SOFA) score, Acute Physiology and Chronic Health Evaluation (APACHE II) score, daily clinical and microbiologic information, and 28-day mortality rate were collected. Because there is not a definitive criterion standard for sepsis, the authors used expert consensus based on clinical, microbiologic, laboratory, and radiologic data collected for each patient during the first 7 days of hospitalization. This expert consensus defined the primary outcome of sepsis, and the primary data analysis was based in the comparison of sepsis versus nonsepsis patients. The cut points to define sensitivity and specificity values, as well as positive and negative likelihood ratios (LRs) for the markers related to sepsis diagnosis, were determined using receiver operative characteristics (ROC) curves. The patients in this study were a prespecified nested subsample population of a larger study. Results: Of 631 patients included in the study, 66% (95% confidence interval [CI] = 62% to 67%, n = 416) had sepsis according with the expert consensus diagnosis. Among these sepsis patients, SOFA score defined 67% (95% CI = 62% to 71%, n = 277) in severe sepsis and 1% (95% CI = 0.3% to 3%, n = 6) in septic shock. The sensitivities for sepsis diagnosis were CD64, 65.8% (95% CI = 61.1% to 70.3%); HMGB-1, 57.5% (95% CI = 52.7% to 62.3%); and s-TREM-1, 60% (95% CI = 55.2% to 64.7%). The specificities were CD64, 64.6% (95% CI = 57.8% to 70.8%), HMGB-1, 57.8% (95% CI = 51.1% to 64.3%), and s-TREM-1, 59.2% (95% CI = 52.5% to 65.6%). The positive LR (LR+) for CD64 was 1.85 (95% CI = 1.52 to 2.26) and the negative LR (LR-) was 0.52 (95% CI = 0.44 to 0.62]; for HMGB-1 the LR+ was 1.36 (95% CI = 1.14 to 1.63) and LR- was 0.73 (95% CI = 0.62 to 0.86); and for s-TREM-1 the LR+ was 1.47 (95% CI = 1.22 to 1.76) and the LR- was 0.67 (95% CI = 0.57 to 0.79). Conclusions: In this cohort of patients suspected of having any infection in the ED, the accuracy of nCD64, s-TREM-1, and HMGB-1 was not significantly sensitive or specific for diagnosis of sepsis. © 2011 by the Society for Academic Emergency Medicine.

Only a small proportion of women infected with Human Papillomavirus (HPV) develop cervical cancer. Host immune response seems to play a role eliminating the viral infection and preventing progression to cancer. Characterization of tumor infiltrating lymphocytes (TILs) in cervical pre-neoplastic lesions and cervical cancer may be helpful to understand the mechanisms that mediate this protection. The aim of this study was to determine if there are differences in the localization and density (cells/mm2) of CD8+ T-cells, CD4+ T-cells and Tregs (CD25 + Foxp3+) in cervical pre-neoplastic lesions and cervical cancer. Immunohistochemical analysis of sections of 96 (26 CIN1, 21 CIN2, 25 CIN3, and 24 SCC) samples revealed that regardless of CIN grades, CD8+ T-cells are more abundant than CD4+, CD25+ and Foxp3+ cells in both the stroma and epithelium. There was a higher density of CD8+ cells in the stroma of cervical cancer compared to CIN3 (OR = 4.20, 95% CI 1.2-15), CIN2 (OR = 7.86, 95% CI 1.7-36.4) and CIN1 (OR = 4.25, 95% CI 1.1-17). Studies evaluating whether these cells are recruited before or after cancer progression will be helpful to understand the role of these cells in the natural history of HPV-induced lesions. © 2012 Springer Science+Business Media B.V.

Excessive beta oscillations (15-25Hz) in the basal ganglia have been linked to the akineto-rigid symptoms of Parkinson's disease (PD) although it remains unclear whether the underlying mechanism is causative or associative. While a number of studies have reported beta activity in the subthalamic nucleus and globus pallidus internus, relatively little is known about the beta rhythm of the motor thalamus and its relation to movement disorders. To test whether thalamic beta oscillations are related to parkinsonian symptoms, we examined the spectral properties of neuronal activity in the ventral thalamic nuclei of five Parkinson's disease patients (two female, age range 50-72years) and compared them to five essential tremor (three female, aged 41-75) and four central pain patients (one female, aged 38-60). Spike and local field potential recordings were obtained during microelectrode-guided localization of thalamic nuclei prior to the implantation of deep brain stimulating electrodes. A total of 118 movement-related neurons in the region of the ventral intermediate nucleus (Vim) were analyzed across all patient groups. Eighty of these neurons (68%) displayed significant oscillatory firing in the beta range with the limbs at rest. In contrast, only 5.7% of the ventral oral posterior (Vop) (χ2 test, p<0.05) and only 7.2% of the ventral caudal (Vc) neurons fired rhythmically at beta frequency (χ2 test, p<0.05). Beta power was significantly decreased during limb movements (ANOVA, p<0.05) and was inversely related to tremor-frequency power during tremor epochs in ET and PD (r2=0.44). Comparison between patient groups showed that Vim beta power was significantly higher in ET patients versus pain and PD groups (ANOVA, p<0.05). The findings suggest that beta oscillations are found predominantly in Vim and are involved in movement but are not enhanced in tremor-dominant Parkinson's patients. © 2014 Elsevier Inc.

Background: Given the acknowledged problems in sepsis diagnosis, we use a novel way with the application of the latent class analysis (LCA) to determine the operative characteristics of C-reactive protein (CRP), D-dimer (DD) and Procalcitonin (PCT) as diagnostic tests for sepsis in patients admitted to hospital care with a presumptive infection.Methods: Cross-sectional study to determine the diagnostic accuracy of three biological markers against the gold standard of clinical definition of sepsis provided by an expert committee, and also against the likelihood of sepsis according to LCA. Patients were recruited in the emergency room within 24 hours of hospitalization and were follow-up daily until discharge.Results: Among 765 patients, the expert committee classified 505 patients (66%) with sepsis, 112 (15%) with infection but without sepsis and 148 (19%) without infection. The best cut-offs points for CRP, DD, and PCT were 7.8 mg/dl, 1616 ng/ml and 0.3 ng/ml, respectively; but, neither sensitivity nor specificity reach 70% for any biomarker. The LCA analysis with the same three tests identified a " cluster" of 187 patients with several characteristics suggesting a more severe condition as well as better microbiological confirmation. Assuming this subset of patients as the new prevalence of sepsis, the ROC curve analysis identified new cut-off points for the tests and suggesting a better discriminatory ability for PCT with a value of 2 ng/ml.Conclusions: Under a " classical" definition of sepsis three typical biomarkers (CRP, PCT and DD) are not capable enough to differentiate septic from non-septic patients in the ER. However, a higher level of PCT discriminates a selected group of patients with severe sepsis. © 2013 Jaimes et al.; licensee BioMed Central Ltd.

Introduction: Burn injuriess affect the quality of life of the injured as a consequence of deformities and loss of bodily function. Objective: Changes in the quality of life related to the health were described in the people who had been affected by burns. Materials and methods: A cross-sectional descriptive study conducted in Medellín, Colombia, enrolled 130 people who suffered burns in the period 2001-2005. A standard quality-of-life survey consisting of 36 questions (the SF-36 scale) was administered. Statistical data were tested with Mann Whitney-U, Student-t, ANOVA, and Kruskal Wallis. Ethical considerations were met within the framework of resolution 8430/93 of the Colombian Ministry of National Health. Results: The number of burns showed an increasing trend each year. Men were most often affected (66.9%) and severe burns were the most common (58%). The main burn sources were the fire flames, targeted attacks and gunpowder burns. The component of change of health upper obtained the average (55.3±19.2) and those of emotional performance (30.2±42.9), and physical performance (31.1±43.6) lowest, finding significant differences in those of physical performance (p=0.039) and general health (p=0.034) according to burn degree. Conclusion: In spite some inconsistency, the most affected quality-of-life components were the physical and emotional performance, with an overall presentation of a low quality-of-life related to health.

Introduction: TP53 is a tumor suppressor gene located on chromosome 17p13.1. This gene is essential for the control of cell cycle and has been found altered in about 50% of all tumor types. Objective: The presence of aneuploidy of chromosome 17 and TP53 gene deletion at 17p13.1 locus was determined in primary solid tumors using the dual-color FISH (fluorescence in situ hybridization). Materials and methods: Thirty-eight samples consisted of several types of primary solid tumors. All samples were mechanically and enzymatically disaggregated with 0.2% collagenase prior to obtaining interphase nuclei. The dual-color FISH was performed using direct fluorescent labeling probes for the chromosome 17 centromere (green signal) and for the TP53 gene locus-specific (orange signal). Results: Characteristic aneuploidy on chromosome 17 was found in 63% (24/38) of the samples. Monosomy occurred most frequently (75%, 18/24), followed by trisomy (17%, 4/24); nullisomy and tetrasomy were less frequent. TP53 gene deletion was found in 89.5% (34/38) of cases. Only four tumors were normal for copy number of chromosome 17 and TP53 gene. The histopathologic study showed that most of the samples were malignant tumors. Conclusions: Aneuploidy of chromosome 17 and deletion at 17p13.1 locus of TP53 gene were genetic alterations found to be very frequent in solid tumors. The dual-color FISH was able to detect both numerical and structural chromosomal abnormalities in interphase nuclei.

Alcoholism was a real problem in Medellín (Colombia) during the first three decades of the XX century. It was focused as a habit that finally dominated people who assumed it. According to the medical knowledge at that time, alcoholism was a social disease with moral, physical, and mental connotations. Therapeutic options for alcoholic patients were limited, and the only mental institution in the city lacked adequate facilities. Consequently, the probability of cure was low, and the prognosis, poor. This article presents the results of a historic investigation about the early diagnosis of alcoholic psychosis in the department of Antioquia (Colombia) between 1900 and 1930. The different clinical approaches to alcoholism and the resources available for treatment are included. We aimed at evaluating the medical knowledge on alcoholism at the beginning or the XX century, and to describe the early steps of the main regional psychiatric center.

Purpose: The aim of the study was to determine whether C-reactive protein (CRP), procalcitonin (PCT), and d-dimer (DD) are markers of mortality in patients admitted to the emergency department (ED) with suspected infection and sepsis. Basic Procedures: We conducted a prospective cohort in a university hospital in Medellín, Colombia. Patients were admitted between August 1, 2007, and January 30, 2009. Clinical and demographic data and Acute Physiology and Chronic Health Evaluation II and Sepsis Organ Failure Assessment scores as well as blood samples for CRP, PCT, and DD were collected within the first 24 hours of admission. Survival was determined on day 28 to establish its association with the proposed biomarkers using logistic regression and receiver operating characteristic curves. Main Findings: We analyzed 684 patients. The median Acute Physiology and Chronic Health Evaluation II and Sepsis Organ Failure Assessment scores were 10 (interquartile range [IQR], 6-15) and 2 (IQR, 1-4), respectively. The median CRP was 9.6 mg/dL (IQR, 3.5-20.4 mg/dL); PCT, 0.36 ng/mL (IQR, 0.1-3.7 ng/mL); and DD, 1612 ng/mL (IQR, 986-2801 ng/mL). The median DD in survivors was 1475 ng/mL (IQR, 955-2627 ng/mL) vs 2489 ng/mL (IQR, 1698-4573 ng/mL) in nonsurvivors (P =.0001). The discriminatory ability showed area under the curve-receiver operating characteristic for DD, 0.68; CRP, 0.55; and PCT, 0.59. After multivariate analysis, the only biomarker with a linear relation with mortality was DD, with an odds ratio of 2.07 (95% confidence interval, 0.93-4.62) for values more than 1180 and less than 2409 ng/mL and an odds ratio of 3.03 (95% confidence interval, 1.38-6.62) for values more than 2409 ng/mL. Principal Conclusions: Our results suggest that high levels of DD are associated with 28-day mortality in patients with infection or sepsis identified in the emergency department. © 2012 Elsevier Inc.
