RESUMO
Mitoviruses were initially known for their presence in the mitochondria of fungi and were considered exclusive to these organisms. However, recent studies have shown that they are also present in a large number of plant species. Despite the potential impact that mitoviruses might have on the mitochondria of plant cells, there is a lack of information about these ancient RNA viruses, especially within the Cannabaceae family. Cannabis sativa has been in the spotlight in recent years due to the growing industrial applications of plant derivatives, such as fiber and secondary metabolites. Given the importance of Cannabis in today's agriculture, our study aimed to expand the knowledge frontier of Mitoviruses in C. sativa by increasing the number of reference genomes of CasaMV1 available in public databases and representing a larger number of crops in countries where its industrial-scale growth is legalized. To achieve this goal, we used transcriptomics to sequence the first mitoviral genomes of Colombian crops and analyzed RNA-seq datasets available in the SRA databank. Additionally, the evolutionary analysis performed using the mitovirus genomes revealed two main lineages of CasaMV1, termed CasaMV1_L1 and CasaMV1_L2. These mitoviral lineages showed strong clustering based on the geographic location of the crops and differential expression intensities.

San Andrés and Providencia are Colombian islands in the Caribbean Sea. San Andrés has 68,283 inhabitants and has registered cases of leprosy in immigrants from continental Colombia. Providencia has 5,037 inhabitants and historically health programs did not have records of the disease, but in 2009 two cases of multibacillary histoid leprosy were confirmed and, subsequently, another two, which represents a prevalence of 8 cases per 10,000 inhabitants and places the island as a hyperendemic site for leprosy. Initially, a 14-year-old girl with histoid leprosy was diagnosed and, exploring this case, her father was diagnosed with the same clinical form of leprosy. Recently, a new intrafamilial patient with multibacillary leprosy and an extrafamilial case of a girl with undetermined leprosy were detected. The objective of this study was to present to the scientific community and the public health officers these clinical cases and to draw the attention of the sanitary authorities on the necessity of establishing continuous programs of leprosy epidemiological surveillance on the island using the new tools available in the Programa de Control de la Lepra (Leprosy Control Program).
San Andrés y Providencia son islas colombianas en el mar de las Antillas. San Andrés tiene 68.283 habitantes y allí se han registrado casos de lepra en inmigrantes provenientes del interior colombiano. Providencia tiene 5.037 habitantes e, históricamente, los programas de salud no tenían registros de la enfermedad; no obstante, en el 2009 se confirmaron dos casos de lepra multibacilar histioide y, posteriormente, otros dos, lo cual representa una prevalencia de 8 casos por 10.000 habitantes y la la convierte en un sitio hiperendémico para lepra. Inicialmente, se diagnosticó lepra histioide en una niña de 14 años y, durante su estudio, se encontró la misma forma clínica de la enfermedad en su padre. Recientemente, se detectó lepra multibacilar en otro miembro de la misma familia y, lepra indeterminada, en una niña de otro núcleo familiar. El objetivo de este trabajo fue presentar estos casos clínicos ante la comunidad científica y los entes de salud pública, y llamar la atención de las autoridades de salud sobre la necesidad de establecer programas de vigilancia epidemiológica continua en la isla, incorporando las nuevas herramientas disponibles en el Programa de Control de la Lepra.

Bone is a dynamic biological tissue that acts as the primary rigid support of the body. Several systemic factors are responsible for pathologies that negatively affect its structural attributes. Although the bone is in continuous renewal by osteogenesis, metabolic diseases are the most common affectations that alter its natural equilibrium. Different techniques based on ionizing radiation are used for the bone diagnosis restrictively. However, if these are not used adequately, the application could present risks for human health. In this paper, it is proposed and explored a new technique to apply an early-stage diagnosis of bone variations. The technique evaluates bone structural conditions from the teeth (used as probes) by applying a structural health monitoring (SHM) methodology. An experimental procedure is described to identify the stiffness variations produced by mechanical drillings done in prepared bone samples. The identification is carried out applying the electromechanical impedance technique (EMI) through a piezo-actuated device in the frequency spectrum 5-20kHz. Three bone samples with incorporated teeth (three teeth, two teeth, and one tooth) were prepared to emulate a mandibular portion of alveolar bone-PDL (periodontal ligament)-tooth system. Piezo-device was attached to the crown of the tooth with an orthodontic bracket allowing the teeth to act as probes. The electrical resistance measurements were computed with an electrical decoupling approach that improved the detection of the drillings; it was due to the increment of the sensitivity of the signals. The results showed that the bone mass reduction is correlated with statistical indices obtained in specific frequency intervals of the electrical resistance. This work suggests the possibility of a future application addressed to a bone diagnosis in a non-invasive way.

La hemimelia tibial se puede presentar en una gran variedad de espectros, desde la hipoplasia tibial hasta la ausencia completa de la tibia con o sin compromiso adjunto cuadricipital, ligamentario, patelar, fibular y/o femoral; esto ha dado lugar a múltiples clasificaciones con implicaciones anatómicas y terapéuticas. Esta enfermedad se ha descrito desde 1841, sin embargo, es la deficiencia más rara en las extremidades inferiores, siendo la más común la deficiencia fibular. Presentamos un paciente con diagnóstico antenatal de pie equino varo bilateral, agenesia de la tibia izquierda y comunicación aurículo ventricular (CIA) con cariotipo normal. Al nacer presenta fascies normales. Se confirma con radiografías la ausencia del tercer rayo de la mano izquierda y la ausencia de la tibia izquierda con ensanchamiento del peroné, tipo 5C en la clasificación de Paley, y pie equino varo aducto bilateral. Nivel de Evidencia: IV
Tibial hemimelia is a broad spectrum disorder, from tibial hypoplasia to complete absence of the tibia with or without quadricipital, ligament, patellar, fibular and / or femoral attachment. This has led to multiple classifications, with their anatomical and therapeutic implications. Although this disorder has been described since 1841, it is the rarest deficiency in the lower extremities, with the most common being fibular deficiency. The case is presented on a patient with an antenatal diagnosis that included bilateral congenital talipes equinovarus, agenesis of the left tibia, and atrioventricular communication with normal karyotype. The facies were normal at birth. Radiographs confirmed the absence of the third ray of the left hand and the absence of the left tibia, with widening of the fibula, type 5C in Paley classification, and bilateral congenital talipes equinovarus. Evidence Level: IV

Resumen Los aneurismas pediátricos son raros y pueden se causados por infección al dañar la pared arterial formando una saculación ciega contigua a su lumen denominada pseudoaneurisma micótico. La mayoría de los casos reportados son de pacientes ancianos con comorbilidades y los agentes causantes más frecuentes son Staphylococcus spp, Salmonella spp, Streptococcus spp y raramente hongos. Se presenta el caso de un niño de 3 años con: diagnóstico reciente de leucemia linfoblástica aguda de precursores B en remisión; alto riesgo de recaída por tratamiento incompleto y antecedente de bacteremia por Staphylococcus epidermidis y fungemia por Cándida tropicalis; vegetaciones cardiacas que hacen embolismo a hígado, bazo, pulmón y cerebro, y pseudoaneurisma micótico parcialmente trombosado de la arteria ilíaca común y externa. El diagnóstico temprano de esta entidad es de vital importancia por el riesgo de ruptura y el manejo quirúrgico dependerá de la localización, el tamaño y las complicaciones asociadas.
Abstract Pediatric aneurysms are rare and can be caused for damaging of the arterial wall secondary to an infection, forming a blind sacculation contiguous to its lumen called mycotic pseudoaneurysm. The majority of reported cases are from elderly patients with comorbidities. The most frequent involucre microorganisms are Staphylococcus spp, Salmonella spp, Streptococcus spp and rarely fungi. We present the case of a 3-year-old boy, with a recent diagnosis of acute lymphoblastic leukemia of B precursors in remission, with a high risk of relapse due to incomplete treatment and a history of bacteremia due to Staphylococcus epidermidis and fungemia due to Candida tropicalis; with cardiac vegetations that produce liver, spleen, lung and brain embolism, in whom a partially thrombosed mycotic pseudoaneurysm of the common and external iliac artery is found. The early diagnosis of this entity is of vital importance because of the risk of rupture. Surgical management will depend on the location, size and associated complications.

Patients with mutations in tubulin-related genes usually present with brain malformations, intellectual disability, epilepsy, microcephaly and ocular abnormalities. In these patients the diagnosis can be suggested by neuroimaging findings. We report a 5-year-old patient with characteristic magnetic resonance imaging findings including malformation of cortical development, fused basal ganglia, large head of the caudate nuclei, absent anterior limbs of the internal capsules, corpus callosum dysgenesis and dysplastic cerebellar vermis. Sequencing of the TUBB2B gene confirmed a heterozygous mutation: c. 260C>A (p. Pro87Gln).

BACKGROUND: Acute respiratory infections are a major cause of morbidity in children and are often caused by viruses. However, the relative severity of illness associated with different viruses is unclear. The objective of this study was to evaluate the risk of hospitalization from different viruses in children presenting with an influenza-like illness (ILI). METHODS: Data from children 5 years old or younger participating in an ILI natural history study from April 2010 to March 2014 was analyzed. The adjusted odds ratio for hospitalization was estimated in children with infections caused by respiratory syncytial virus (RSV), metapneumovirus, bocavirus, parainfluenza viruses, rhinovirus/enterovirus, coronavirus, adenovirus, and influenza. RESULTS: A total of 1486 children (408 outpatients and 1078 inpatients) were included in this analysis. At least one virus was detected in 1227 (82.6%) patients. The most frequent viruses detected as single pathogens were RSV (n = 286), rhinovirus/enterovirus (n = 251), parainfluenza viruses (n = 104), and influenza A or B (n = 99). After controlling for potential confounders (age, sex, recruitment site, days from symptom onset to enrollment, and underlying illnesses), children with RSV and metapneumovirus infections showed a greater likelihood of hospitalization than those infected by parainfluenza viruses (OR 2.7 and 1.9, respectively), rhinovirus/enterovirus (OR 3.1 and 2.1, respectively), coronaviruses (OR 4.9 and 3.4, respectively), adenovirus (OR 4.6 and 3.2, respectively), and influenza (OR 6.3 and 4.4, respectively). CONCLUSIONS: Children presenting with ILI caused by RSV and metapneumovirus were at greatest risk for hospitalization, while children with rhinovirus/enterovirus, parainfluenza, coronavirus, adenovirus, and influenza were at lower risk of hospitalization.

Feces-contaminated water is a vehicle of transmission of potentially pathogenic microorganisms responsible for illnesses that represent main causes of death worldwide. A protocol for detection of intestinal parasites in great volumes of water was optimized. It includes: membrane filtration, mechanical agitation with detergent, centrifugation, chemical concentration with Mini Parasep® and microscopic examination. From samples of feces-contaminated water containing parasitic forms, a total recovery percentage of 85.7 percent of parasites was achieved after tests. This procedure provides a useful alternative method that could be subjected to validation as a routine methodology in the diagnosis of microbiological water quality(AU)

RATIONALE: Despite major advances in treatment, acute diarrhea continues to be a public health problem in children under five years. There is no systematic approach to treatment and most evidence is assembled comparing active treatment vs. placebo. OBJECTIVE: Systematic review of evidence on efficacy of adjuvants for treatment of acute diarrhea through a network meta-analysis. METHODS: A systematic search of multiple databases searching clinical trials related to the use of racecadotril, smectite, Lactobacillus GG, Lactobacillus reuteri, Saccharomyces boulardii and zinc as adjuvants in acute diarrhea was done. The primary endpoint was duration of diarrhea. Information is displayed through network meta-analysis.The superiority of each coadjutant was analyzed by Sucra approach. RESULTS: Network meta-analysis showed race cadotril was better when compared with placebo and other adjuvants. Sucra analysis showed racecadotril as the first option followed by smectite and Lactobacillus reuteri. INTERPRETATION: Considering a strategic decision making approach, network meta-analysis allows us to establish the therapeutic superiority of racecadotril as an adjunct for the comprehensive management of acute diarrhea in children aged less than five years.

OBJECTIVES: To evaluate whether daily administration of Lactobacillus reuteri DSM 17938 reduces the frequency and duration of diarrheal episodes and other health outcomes in day school children in Mexico. METHODS: Healthy children (born at term, aged 6-36 months) attending day care centers were enrolled in this randomized, double-blind, placebo-controlled trial. They received L reuteri DSM 17938 (dose 10(8) colony-forming unit; n = 168) or identical placebo (n = 168) by mouth, daily for 3 months, after which they were followed-up after a further 3 months without supplementation. RESULTS: Data from all children were included in the final analysis. L reuteri DSM 17938 significantly reduced the frequency and duration of episodes of diarrhea and respiratory tract infection at both 3 and 6 months (P < .05). Additionally, the number of doctor visits, antibiotic use, absenteeism from day school and parental absenteeism from work were significantly reduced in the L reuteri group (P < .05). A cost-benefit analysis revealed significant reductions in costs in the L reuteri-treated children. No adverse events related to the study product were reported. CONCLUSIONS: In healthy children attending day care centers, daily administration of L reuteri DSM 17938 had a significant effect in reducing episodes and duration of diarrhea and respiratory tract infection, with consequent cost savings for the community.

El propósito del estudio fue identificar los conocimientos y las practicas de cuidado bucal de las madres de niños menores de 6 años. Se entrevistaron con base en formulario estructurado, 243 madres o personas adultas responsables de niños menores de 6 años, de los estratos bajo y alto de las ciudades de Bogotá, Medellín, Cartagena y Manizales. Los resultados muestran que el 60.0 por ciento de las madres afirma haber recibido información sobre como cuidar los dientes primarios de su hijo (a). Cerca de la mitad de las mujeres (47.7 por ciento) considera que la higiene bucal es suficiente para evitar la caries, las demás creen que son necesarias otras prácticas como proporcionar una buena alimentación (65 por ciento), visitar al odontólogo (45 por ciento) y evitar el consumo de dulces (10 por ciento). El momento en que se inicio el cepillado difiere de manera significativa entre el estrato alto y el bajo (p = 0.009). Mientras el 56 por ciento de las madres del estrato alto empezaron a cepillar el niño antes de cumplir el primer año, el 59 por ciento de las del estrato bajo empezaron después del primer año. El 89.3 por ciento de los niños usa crema dental para cepillarse. El 35.5 por ciento empezó a usarla antes del primer año de vida y solo una baja proporción (10.8 por ciento) lo hizo a partir del tercer año. El 71 por ciento de las mujeres contestaron que nunca han recibido información sobre la cantidad y el tipo de la crema dental que debe usar para el cepillado del niño. El 14.0 por ciento de ellas no sabe para que sirve el flúor, el 86 por ciento considera que el flúor sirva para prevenir la caries, blanquear los dientes o como desinfectante. Se concluyen que aunque las madres manejan una buena cantidad de información sobre el cuidado bucal de sus hijos, falta mas claridad y comprensión de algunos conceptos de modo que puedan ponerlos en práctica conscientemente...
