Cutaneous Horn Presentation in Porokeratotic Eccrine Ostial and Dermal Duct Nevus. A Brief Review and Case Report.

ABSTRACT: Porokeratotic eccrine ostial and dermal duct nevus is a rare adnexal hamartoma characterized by the presence of a cornoid lamella exclusively overlying eccrine acrosyringia. Different clinical presentations have been reported in the literature. Here, we report a case of a 6-year-old girl diagnosed with porokeratotic eccrine ostial and dermal duct nevus confirmed by histopathologic study. Atypical lesions are described as whitish, warty-looking neoformations located in the anterolateral region of the right hip (cutaneous horn).

Galectin-9 Expression is Correlated to Cervical Squamous Cell Carcinoma Progression and Overall Survival.

Purpose: To determine whether galectin-9 gene (LGALS9) expression is correlated with cervical cancer progression, clinicopathological characteristics, and overall survival. To determine the biological processes and the abundance of tumour infiltrating immune cells related to the expression of LGALS9. Patients and Methods: The study was conducted in two phases: 1) The expression level of LGALS9 was determined using the data of 193 squamous cell carcinoma (SCC) samples from The Cancer Genome Atlas (TCGA) database. Biological processes and tumour infiltrating cells associated to LGALS9 expression were evaluated using gene set enrichment analysis (GSEA) and tumour immune estimation resource (TIMER). 2) Independently, galectin-9 was identified in 40 SCC samples by immunohistochemistry and optical density quantified using ImagePro® software. Results: The LGALS9 gene showed increased expression in cervical cancer samples. A higher expression level in SCC was related to better overall survival and to early clinical stages. GSEA showed that tumours with higher expression of LGALS9 were enriched in immune pathways such as interferon_alpha_response, and complement, the analysis of TIMER database showed a positive correlation between the expression level of LGALS9 and the abundance of tumour infiltrating immune cells. In addition, higher expression of galectin-9 was found in biopsies of SCC patients at early clinical stages, showing a trend of better survival. Conclusion: Higher expression levels of LGALS9 and galectin-9 in SCC were related to early clinical stages and better prognosis. GSEA and TIMER analysis suggested that galectin-9 could play an antitumor role in cervical SCC.

Acral Melanoma Is Infiltrated with cDC1s and Functional Exhausted CD8 T Cells Similar to the Cutaneous Melanoma of Sun-Exposed Skin.

Acral melanoma (AM) is the most common melanoma in non-Caucasian populations, yet it remains largely understudied. As AM lacks the UV-radiation mutational signatures that characterize other cutaneous melanomas, it is considered devoid of immunogenicity and is rarely included in clinical trials assessing novel immunotherapeutic regimes aiming to recover the antitumor function of immune cells. We studied a Mexican cohort of melanoma patients from the Mexican Institute of Social Security (IMSS) (n = 38) and found an overrepresentation of AM (73.9%). We developed a multiparametric immunofluorescence technique coupled with a machine learning image analysis to evaluate the presence of conventional type 1 dendritic cells (cDC1) and CD8 T cells in the stroma of melanoma, two of the most relevant immune cell types for antitumor responses. We observed that both cell types infiltrate AM at similar and even higher levels than other cutaneous melanomas. Both melanoma types harbored programmed cell death protein 1 (PD-1+) CD8 T cells and PD-1 ligand (PD-L1+) cDC1s. Despite this, CD8 T cells appeared to preserve their effector function and expanding capacity as they expressed interferon-γ (IFN-γ) and KI-67. The density of cDC1s and CD8 T cells significantly decreased in advanced stage III and IV melanomas, supporting these cells' capacity to control tumor progression. These data also argue that AM could respond to anti-PD-1-PD-L1 immunotherapy.

Evaluación de la movilidad del ácido 2,4-diclorofenoxiacético en suelos ándicos del departamento del Cauca, Colombia

El herbicida ácido 2,4 - diclorofenoxiacético (2,4-D) es un ácido selectivo y sistémico que, desde 1940, es ampliamente utilizado en suelo agrícolas, de todo el mundo. Su uso radica a su selectividad entre la vegetación de hoja ancha y cultivos de gramíneas y como regulador del crecimiento vegetal; sin embargo, este herbicida se puede acumular en el ambiente y, adicionalmente, puede ser transportado por lixiviación, a través del suelo, llegando a contaminar aguas subterráneas, lo que genera un alto riesgo para el ambiente y la salud del ser humano. El estudio de la movilidad del 2,4-D en suelos con alto contenido de materia orgánica permitió conocer, que no solo la materia orgánica se correlaciona indirectamente con la movilidad de este compuesto, sino que, también, influye la humedad, al reducir la lixiviación y el potencial de contaminación del recurso hídrico subterráneo, mientras que la conductividad hidráulica se relaciona, de manera directa, con la lixiviación de este herbicida.

The herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) is a selective and systemic acid that has been widely used in agricultural soils since 1940. Its use lies in its selectivity between broadleaf vegetation and grass crops, and as a regulator of plant growth. However, this herbicide can accumulate in the environment, and additionally, it can be transported by leaching through the soil, contaminating groundwater, which generates a high risk for the environment and human health. In this study, the mobility of 2,4-D in organic-matter-rich soils was assessed. The results revealed that not only the organic material is indirectly correlated with the mobility of this compound but also influences humidity and reduces leaching and potential pollution of groundwater resources, whereas hydraulic conductivity is directly related to herbicide leaching.

Serum Levels of Galectin-9 are Increased in Cervical Cancer Patients and are Higher in Advanced Clinical Stages.

Purpose: Cervical cancer (CC) is the second most frequent cancer in undeveloped countries. Serum biomarkers could be useful for evaluation of the treatment response and as a complementary means to improve diagnosis. The expression of galectin-9 is altered in cancer tissue, and higher concentrations are found in the serum of cancer patients. The objectives of this study were (a) to determine the serum galectin-9 concentration in patients with intraepithelial lesions and CC, (b) to determine if the concentration was related to the clinicopathological characteristics and (c) to determine if the galectin-9 concentration was related to its expression level in tumour tissue. Patients and Methods: In all, 222 serum samples from women with different diagnoses, including premalignant lesions and CC, as well as samples from women with normal cytology were included in the study. The serum galectin-9 concentration was determined by ELISA. To evaluate the expression level of galectin-9 in CC tissue, immunohistochemistry was performed in 34 CC biopsy specimens. Results: The galectin-9 concentration in the serum of CC patients (8.171 ng/mL) was increased compared with serum from women with normal epithelia (4.654 ng/mL) and those with low-grade (4.806 ng/mL) and high-grade (5.354 ng/mL) intraepithelial lesions (p value < 0.0001). The area under the ROC curve considering the CC group and the control group was 0.882. The optimal cut-off value was ≥6.88 ng/mL, the specificity obtained was 100%, and the sensitivity was 68.2%. In the CC group, the analysis of the clinical stage showed an increase of galectin-9 in the advanced stage IV group. Serum galectin-9 was not related to the level of galectin-9 expression in tissue, which suggests that galectin-9 is not secreted by tumour cells. Conclusion: The serum galectin-9 concentration is related to cancer progression, as the level of this protein is higher in patients with advanced-stage disease.

Primary hepatic gastrinoma, extremely rare case presentation and its surgical resolution, in a third level hospital in Mexico.

The gastrinomas are rare functional neuroendocrine neoplasms, most are localized to the duodenum (70-90%) or the pancreas (2-30%), but less common ectopic sites have been reported. The primary hepatic gastrinoma is extremely rare, with less tan 40 cases reported in the medical literature. Its low incidence and its non specific clinical presentation make it a difficult disease to diagnose. Providing a timely diagnosis the patient can be treated by surgical resection with high chances of success. The objective of this paper is to describe a case of primary hepatic gastrinoma in Mexico, successfully treated by right liver segmentectomy.

Hallmarks of glycogene expression and glycosylation pathways in squamous and adenocarcinoma cervical cancer.

BACKGROUND: Dysregulation of glycogene expression in cancer can lead to aberrant glycan expression, which can promote tumorigenesis. Cervical cancer (CC) displays an increased expression of glycogenes involved in sialylation and sialylated glycans. Here, we show a comprehensive analysis of glycogene expression in CC to identify glycogene expression signatures and the possible glycosylation pathways altered. METHODS: First, we performed a microarray expression assay to compare glycogene expression changes between normal and cervical cancer tissues. Second, we used 401 glycogenes to analyze glycogene expression in adenocarcinoma and squamous carcinoma from RNA-seq data at the cBioPortal for Cancer Genomics. RESULTS: The analysis of the microarray expression assay indicated that CC displayed an increase in glycogenes related to GPI-anchored biosynthesis and a decrease in genes associated with chondroitin and dermatan sulfate with respect to normal tissue. Also, the glycogene analysis of CC samples by the RNA-seq showed that the glycogenes involved in the chondroitin and dermatan sulfate pathway were downregulated. Interestingly the adenocarcinoma tumors displayed a unique glycogene expression signature compared to squamous cancer that shows heterogeneous glycogene expression divided into six types. Squamous carcinoma type 5 (SCC-5) showed increased expression of genes implicated in keratan and heparan sulfate synthesis, glycosaminoglycan degradation, ganglio, and globo glycosphingolipid synthesis was related to poorly differentiated tumors and poor survival. Squamous carcinoma type 6 (SCC-6) displayed an increased expression of genes involved in chondroitin/dermatan sulfate synthesis and lacto and neolacto glycosphingolipid synthesis and was associated with nonkeratinizing squamous cancer and good survival. In summary, our study showed that CC tumors are not a uniform entity, and their glycome signatures could be related to different clinicopathological characteristics.

Caries de infancia temprana: diagnóstico e identificación de factores de riesgo / Early childhood caries: diagnosis and identification of risk factors

La caries de infancia temprana ha sido definida con múltiples denominaciones; en las últimas décadas se ha descrito como una enfermedad de origen multifactorial presente en infantes hasta los 71 meses de edad. El objetivo de esta revisión es describir la clasificación, características clínicas, epidemiología, etiología y factores condicionantes externos de la caries de infancia temprana, a través de una extensa revisión bibliográfica, realizada por un grupo de estudio de la Sociedad Peruana de Odontopediatría, durante seis meses (2013-2014); con el fin de brindar in- formación y herramientas, a los trabajadores de la salud en el Perú, útiles en el diagnóstico de la enfermedad y en la identificación de factores de riesgo asociados. La característica de la etiología de la caries de infancia temprana, radica en la influencia de factores únicos en los infantes, relacionados a la implantación temprana de los microorganismos cariogénicos, a la inmadurez del sistema de defensa del huésped, así como a los patrones del comportamiento asociados a la alimentación y la deficiente higiene oral en los infantes. De acuerdo a lo estudiado, la prevalencia de caries de infancia temprana en el Perú oscila entre 31.5% y 93%. Los factores socio culturales presentan una marcada influencia en la instauración, progresión y severidad de la enfermedad; adicionalmente, ciertos condicionan te s externos, como la conducta del niño, el nivel de conocimiento y actitud de los padres, malnutrición y la presencia de enfermedades crónicas o procesos infecciosos específicos como la otitis, se han relacionado con un mayor riesgo de caries dental en infantes...

Early childhood caries has been defined with multiple names; in recent decades has been described as a multifactorial origin disease, present in infants up to 71 months. The aim of this review is to describe the classification, clinical features, epidemiology, etiology and determinants external factors of early childhood caries, through an extensive literature review, conducted by a group of study of the Peruvian Society of Dentistry for six months (2013-2014); in order to provide information and tools to health workers in Peru, useful in the diagnosis of disease and identification of associated risk factors. The characteristic of the etiology of early childhood caries, lies in the influence of unique factors in infants, related to the early implementation of cariogenic microorganisms, to the immaturity of the host defense system, as well as behavioral patterns associated with food and poor oral hygiene in children. According to the study, the prevalence of early childhood caries in Peru varies between 31.5% and 93%. Socio- cultural factors have a marked influence on the onset, progression and severity of disease; additionally, certain external factors such as the child's behavior, the level of knowledge and parents attitude, malnutrition and the presence of chronic diseases or specific infectious conditions such as ear infections, have been associated with an increased risk of dental caries in infants...
