RESUMEN
Polycystic ovary syndrome (PCOS) is a multifactorial and polygenic endocrine-metabolic disorder in women of reproductive age. SNPs in the THADA gene have been identified as PCOS risk loci. In this study, we evaluated the frequency of five polymorphisms in a sample of Colombian women with PCOS, and their association with clinical and endocrine-metabolic parameters. Forty-nine women with PCOS and forty-nine healthy women were included. Allelic discrimination was performed in the THADA gene by iPLEX and the MassARRAY system (Agena Bioscience). Haploview software was conducted to analyze the linkage disequilibrium (LD) and haplotypes of polymorphisms. There was an association between the genotypes TT of rs12468394, CC + AA of rs12468394, and GG of rs6544661 and an increase in the levels of free testosterone. The CC + AA of rs12468394 genotype also was associated with an increase of androstenedione levels. THADA gene SNPs were not associated with PCOS risk. There was very strong LD among the SNPs. No significant differences in the frequency of haplotypes between groups were observed. The statistical power of this analysis is low because of the small number of samples analyzed. Additional studies involving large populations of Colombian women with PCOS are needed to verify the role of the THADA gene in this disorder.
RESUMEN
Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is an uncommon form of non-Hodgkin lymphoma (cancer of the immune system) that can develop around breast implants. Breast implants are among the most commonly used medical devices for cosmetic or reconstructive purposes. In the past few years, the number of women with breast implants diagnosed with anaplastic large cell lymphoma (ALCL) has increased, and several studies have suggested a direct association between breast implants and an increased risk of this disease. Although it has been hypothesized that chronic stimulation of the immune system caused by implant materials and biofilms as well as a possible genetic predisposition play an important role in this disease, the cellular and molecular causes of BIA-ALCL are not fully understood. This review aims to describe the current understanding around the environmental and molecular drivers of BIA-ALCL as well as the genetic and chromosomal abnormalities identified in this disease to date.

Normal-weight obesity (NWO) syndrome has been shown to be associated with cardiometabolic dysfunction. However, little is known regarding this potential relationship in Latin American children and adolescents. The aim of this study was two-fold: (i) to investigate whether Colombian youth with NWO syndrome have a poorer cardiometabolic profile and physical fitness performance than normal-weight lean (NWL) peers; and (ii) to determine if physical fitness levels are related to prevalence of normal-weight obesity in youth. This was an analytical cross-sectional study of 1919 youths (9-179 years old, 53.0% girls) in the capital area of Colombia. NWO was defined as a body mass index < 25 kg/m2 and a validated body fat percentage above the sex-age-specific 90th percentile for Colombian children and adolescents. Body fat was estimated using bioelectrical impedance analysis, cardiorespiratory fitness (CRF) was estimated using the 20-meter shuttle run test, and muscular fitness with the handgrip test. Biochemical profile blood samples were collected for cardiometabolic risk factors. After adjusting for chronological age, pubertal stage, and Mediterranean diet adherence, the NWO group (boys and girls) had significantly higher values for cardiometabolic risk factors, and waist circumference (WC) than the NWL group. The prevalence of NWO was lower in youth classified with healthy CRF (boys, odds ratio (OR) = 0.54, 95% confidence interval (CI) 0.37 to 0.78; girls, OR = 0.35, 95% CI 0.24 to 0.50), p < 0.001. Our findings indicate that using only body mass index for the assessment of cardiometabolic risk likely misrepresents true adiposity and suggest the need to include the assessment of body fat in the routine clinical evaluation of individuals during childhood and adolescence.

Objective: To present one case of Paget's disease (PD) of the breast without associated ductal carcinoma, and to conduct a review of the literature on its diagnosis and treatment. Materials and methods: 59-year-old woman with a two-year history of a chronic erythematous, ulcerated, itchy lesion in the left nipple, initially treated dermatologically with topical steroids with no improvement, finally visits a primary healthcare institution in the city of Tunja, Colombia for diagnosis. A biopsy and histochemical testing were performed to make the diagnosis and the lesion was then treated with central quadrantectomy. The post-operative pathology testing was negative for malignancy, without recurrence at one-year follow-up. A search was conducted in the PubMed, SciELO, ProQuest, ScienceDirect and Google Scholar databases using the terms "Paget´s Disease," "Breast Neoplasms," "Mammography," "Ultrasonography," Mammary," "Biopsy," and "Mastectomy," tracking bibliographic review articles, editorials, reports and clinical case series in English and Spanish, without time limitation. Results: Overall, 11 publications were included consisting of 5 case reports, 3 case series, 1 review of the literature based on a clinical case, and 2 letters to the editor describing cases related to Paget's disease of the nipple with no associated carcinoma. The diagnosis was based on the clinical suspicion of the disease and a biopsy of the lesion. Histochemistry was useful for the differential diagnosis: treatment options ranged from mastectomy to nipple-areolar complex resection. Radiotherapy has also been used. Conclusions: The diagnosis of Paget's disease with no associated ductal carcinoma is based on early clinical suspicion and histopathology of the nipple- areolar complex. There is no consensus regarding surgical management of this lesion. Follow-up studies of this subgroup of patients treated with radiotherapy or conservative surgery are required.
TITULO: ENFERMEDAD DE PAGET DE LA MAMA, SIN CARCINOMA DUCTAL ASOCIADO: REPORTE DE CASO Y REVISIÓN DE LA LITERATURA. Objetivo: Presentar un caso de enfermedad de Paget (EP) de la mama, sin carcinoma ductal asociado, y realizar una revisión de literatura respecto a su diagnóstico y tratamiento. Materiales y métodos: Mujer de 59 años, con lesión pruriginosa, eritematosa y ulcerada crónica, en pezón izquierdo, de 2 años de evolución, quien recibió inicialmente manejo dermatológico con corticoides tópicos sin mejoría clínica, que acude finalmente a una institución de atención primaria en Tunja (Colombia) para su diagnóstico, el cual se realizó por biopsia mediante inmunohistoquímica y posterior manejo por cuadrantectomía central con patología posquirúrgica negativa para malignidad, sin recurrencia al año de seguimiento.

Resumen OBJETIVO: Comparar el comportamiento clínico del parto vertical con el horizontal en embarazadas atendidas en dos centros de salud de Cusco, Perú. MATERIALES Y MÉTODOS: Estudio descriptivo, comparativo y prospectivo con un componente correlacional efectuado en dos centros de salud de la ciudad de Cusco, Perú, del 1 de septiembre del 2020 al 31 de enero del 2021, en mujeres embarazadas que tuvieron parto vertical u horizontal. El cálculo del tamaño de muestra se estableció con el programa estadístico EPIDAT mediante la comparación de medias de grupos independientes. RESULTADOS: Se estudiaron 212 pacientes (106 en parto vertical y 106 en posición de litotomía). En las pacientes con parto horizontal se registraron 3 casos de activación de código rojo (1.42%) con sangrado máximo de 2500 cc. El grado de desgarro vaginal más frecuente fue 1, en 103 mujeres (48.58%). La involución uterina en los dos grupos, a las 6 h, fue de 13 cm en 80 mujeres (37.74%), a las 12 h de 12 cm en 83 mujeres (39.15%) y para las 24 h de 11 cm en 84 mujeres (39.62%). Las horas mínimas de trabajo de parto fueron 2.38 h en el grupo de parto vertical; el puntaje Apgar más bajo fue 7 al primer minuto (1.42%) y al minuto 5 (0.47%). CONCLUSIONES: El parto vertical puede ofrecer ventajas significativas en comparación con el horizontal en algunas variables: trabajo de parto más corto, Apgar al minuto e involución uterina. Para las demás variables estudiadas no se encontraron diferencias estadísticamente significativas.
Abstract OBJECTIVE: To compare the clinical behavior of vertical delivery and delivery in the lithotomy position in pregnant women attended in two health centers in Cusco, Peru. MATERIALS AND METHODS: Descriptive, comparative and prospective study with a correlational component carried out in two health centers in the city of Cusco, Peru, from September 1, 2020 to January 31, 2021 in pregnant women who delivered vertically or horizontally. The sample size was calculated using the EPIDAT statistical program by comparing the means of independent groups. RESULTS: 212 patients were studied (106 in vertical delivery and 106 in lithotomy position). In horizontal delivery patients there were 3 cases of code red activation (1.42%) with maximum bleeding of 2500 cc. The most frequent vaginal tear grade was 1, in 103 women (48.58%). Uterine involution in the two groups, at 6 h, was 13 cm in 80 women (37.74%), at 12 h 12 cm in 83 women (39.15%) and by 24 h 11 cm in 84 women (39.62%). Minimum labor hours were 2.38 h in the vertical delivery group; the lowest Apgar score was 7 at 1 min (1.42%) and at 5 min (0.47%). CONCLUSIONS: Vertical delivery may offer significant advantages compared to horizontal delivery in some variables: shorter labor, Apgar at minute and uterine involution. For the other variables studied, no statistically significant differences were found.
